    Technological Field
    [001] The present invention relates to a pressure release structure for a battery box installed in an electric vehicle as a source of propulsion energy for the vehicle. Existing Technology
    [002] Vehicle battery boxes in which the opening of a case member is covered with a cover member, a sealing member is interposed between the case member and the cover member, and a case chamber is hermetically sealed sealed, are known in the prior art (for example, with reference to patent document 1). Prior Art Documents Patent Documents Patent Document 1: Publicly Available Patent Application JP 2010-232330. Patent Document 2: Publicly Available Patent Application JP 2006-236775 Disclosure of the Invention Problems to be solved by the invention
    [003] However, although the case chamber can be hermetically seen in these battery boxes installed in conventional vehicles, there is a problem that the units do not have a function so that when the internal pressure of the camera chamber box has gone up due to gas production, internal gases are discharged to the outside.
    [004] Specifically, in the case of a battery box installed in the vehicle, when an adverse event such as overload occurs, gases are produced from the battery module which is located inside the box chamber and which includes multiple cells battery, in some cases leading to increased internal pressure from the housing chamber. As indicated, for example, in Publicly Available Patent Application JP 2006-236755 (Patent Document 2), the production of gas from a battery module occurs when gases are produced inside the battery cells, and as the internal pressure increases, a relatively thin section of the sealing member on the inner side of the cell breaks, causing the gases to be discharged to the outside (inside the case chamber).
    [005] In view of the problem described above, it is an objective of the present invention to provide a pressure release structure for a battery pack installed in a vehicle, whereby when the internal pressure of the case chamber has increased due to the production of gases, the Internal gases are discharged to the outside through a separable opening of a portion with a weak junction. Means Used to Solve the Above-mentioned Problems
    [006] To achieve the above objective, according to the present invention, a battery case includes a lower battery case structure and an upper battery case cover, and a battery module is arranged in the lower case structure. battery box.
    [007] In this vehicle-mounted battery box, the top cover of the battery box is securely attached to the bottom structure of the battery box by a sealing member that extends continuously around the entire perimeter along the respective edge portions outer peripherals.
    [008] The top cover of the battery box has a scalable, deformable portion with a difference in height at least in the vertical direction.
    [009] In an area corresponding to the deformable stepped portion within the sealing member extending continuously around the entire perimeter, a weak junction portion is established. Effects of the Invention
    [010] As described above, the top cover of the battery box is provided with a deformable stepped portion having a difference in height at least in the vertical direction. Then, in an area of the sealing member that extends continuously around the entire perimeter, the area corresponding to the deformable staggered portion, a weak junction portion of less joint strength is established than in the rest of the joined portion.
    [011] Consequently, when gases are produced from the battery module disposed inside the box chamber, and the internal pressure of the box chamber increases, the internal pressure is concentrated in a section that protrudes farther to the side. from the center of the box within the box structure, specifically the deformable staggered portion of the top cover of the battery pack. Due to this concentration of internal pressure, in the deformable staggered portion, the top cover of the battery box undergoes deformation in a direction that eliminates the height difference of the step in the vertical direction, that is, in the vertical direction from the bottom step to the direction of the highest step. Due to this deformation of the lid, the joint of the portion with weak junction that was established in the area corresponding to the deformable staggered portion opens, the peripheral edge portion of the upper cover of the battery box separates from the peripheral edge portion ex- end of the bottom structure of the battery box, and an opening is formed in the portion with weak junction. For this reason, when the internal pressure of the case chamber has increased due to the production of gases, the internal gases are discharged to the outside through the opening in the weak junction portion, without inducing rupture or opening of the top cover of the battery box.
    [012] Thus, the internal pressure concentrated in the deformable staggered portion of the upper cover of the battery box induces deformation of the upper cover of the battery box, and associated with the deformation of the cover, the weak junction portion opens, forming a opening through which the case chamber communicates with the outside air. For this reason, when the internal pressure of the case chamber has increased due to production and gases, the internal gases can be discharged out through the separable opening of the weak junction portion.

Detailed configuration of pressure release structure provided for the battery box
    [047] Figures 4 to 10 show the detailed configuration of the pressure release structure provided for the battery box of the first modality. The detailed configuration of the pressure release structure provided for the battery box is described below based on Figures 4 to 10.
    [048] The pressure release structure provided for the BP battery case of the first embodiment is provided with a strong strong adhesive sealing member 81 (sealing member), a weak adhesive sealing member 82 (sealing member), portions deformable staggered 83, a pair of weak junction portions 84, and a pair of indented areas 85.
    [049] As shown in Figure 4, in the BP battery box, the battery box case 1 includes the lower battery box structure 11 and the upper battery box cover 12, and the battery module 2 is arranged in the bottom frame of the battery box 11 (Figure 3). The lower battery box structure 11 and the upper battery box cover 12 are both formed of a metallic material such as iron.
    [050] The top cover of the battery box 12 is firmly joined to the bottom structure of the battery box 11 by the weak adhesive sealing member 82 and the strong adhesive sealing member 81 that extends continuously around the entire perimeter along of the respective outer peripheral edge portions 11a, 12a (Figure 5).
    [051] As shown in Figure 4, the top cover of the battery box 12 is provided with the deformable stepped portions 83, which have a difference in height in the vertical direction. As shown in Figure 5, the weak junction portions 84, in which the strength of the junction is lower than that of other joined portions, are positioned in areas within the weak adhesive sealing member 82 and the strong adhesive sealing member 81 that extends continuously around the entire perimeter, the areas corresponding to the deformable staggered portions 83.
    [052] The detailed constitution of the deformable staggered portions 83 will be described based on Figure 4.
    [053] In the upper surface sections of the upper lid of the baffle box 12, a first flat portion 12b is formed, a second flat portion 12c which is smaller than the first flat portion 12b, and a first inclined surface 12d connecting the first flat portion 12b and the second flat portion 12c. A third flat portion 12e is formed which is smaller than the first flat portion 12b, but higher than the second flat portion 12c, and a second inclined surface 12f connecting the third flat portion 12e and the second flat portion 12c.
    [054] In the left and right surface sections of the battery cover top cover 12, a left inclined side surface 12g and a right inclined side surface 12h are formed that extend diagonally downwards from end portions transversal to the vehicle the first flat portion 12b, the second flat portion 12c, the first inclined surface 12d, the third flat portion 12e, and the second inclined surface 12f.
    [055] The basic constitution of the deformable stepped portions 83 is formed by a first edge line 83a in which side surfaces inclined to the left and right 12g, 12h and the first flat portion 12b intersect, one second from the line of edge 83b on which left and right angled side surfaces 12g, 12h and the first flat portion 12d intersect, and a third edge line 83c on which left and right angled side surfaces 12g, 12h and the second flat portion 12c intersect. A fourth edge line 83d is also formed on which the left and right sloping side surfaces 12g, 12h and the second sloping portion 12f intersect, and a fifth edge line 83e on which the left and right sloping side surfaces 12g, 12h and the third flat portion 12e intersect.
    [056] The strong adhesive sealing member 81 and the weak adhesive sealing member 82 are adhesive sealing members made of a urethane based adhesive. As a strong adhesive sealing member 81, an adhesive sealing member having an adhesion resistance that satisfies certain environmental conditions and reported loading conditions is employed. Here, environmental conditions are conditions that ensure the sealing capacity as to the impermeability to water inhibiting the infiltration of water into the case chamber during washing of cars with high pressure or travel on flooded roads, and to be impermeable to the air keeping the interior of the case chamber in an airtight state in the face of changes in ambient temperature. The reported loading conditions are conditions of resistance such that the occurrence of breakage or breakage in response to impact information during a frontal collision or side collision, or to vibration information coming from the road surface, is inhibited.
    [057] As a weak adhesive seal member 82, an adhesive seal member is employed which, although it has an adhesive resistance that satisfies the environmental conditions and the load conditions reported, has an ink seal having an adhesive resistance lower than the strong adhesive sealing member 81. The weak adhesive sealing member 82 has a property by which, when an intense force is applied in a direction that separates the adherent after curing, the adhesive fragments themselves (failure in cohesion), rather than a property by which the adhesive and the adherent separate (interfacial rupture) (see Figure 12).
    [058] As shown in Figure 5, the weak adhesive sealing member 82 fills the recessed areas 85 that have been provided for areas with symmetry on the left and right in the transverse direction of the vehicle, corresponding to the deformable stepped portions 83, in the edge position outer peripheral 11a of the bottom structure of the battery box 11. Specifically, as shown in Figure 6, the weak adhesive sealing member 82 is interposed for the purpose of securing the weak junction portions 84 having a lower joining force than others joined portions, in areas corresponding to the deformable stepped portions 83 (the edge lines 83a, 83b, 83c, 83d, 83e), whose areas are sandwiched between two of the corner pins 72, 72.
    [059] As shown in Figure 5, the strong adhesive sealing member 81 is continuously interposed around the entire perimeter along the outer peripheral edge portion 11a, including the recessed areas 85, of the lower battery box structure 11. The joined structures of the lower battery box structure 11 and that of the upper battery box cover 12 will be described in more specific terms here.
    [060] As shown in Figure 7, the joint structure in a normal jointed portion is one in which only the strong adhesive sealing member 81 is interposed within a SS sealing space between the respective outer peripheral edge portions 11a, 12a .
    [061] As shown in Figure 8, the structure joined in a corner portion pinned is one in which only the strong adhesive sealing member 81 is interposed within the SS sealing space, in a slightly inwardly facing position. with respect to the corner pin 72, in the respective outer peripheral edge portions 11a, 12a.
    [062] As shown in Figure 9, the joint structure on a grounding portion secured by a stud is one in which only the strong adhesive sealing member 81 is interposed within the SS sealing space, in an internal position away from the stud. grounding 71, in the respective outer peripheral edge portions 11a, 12a. In the position secured by the grounding pin 71, the outer peripheral edge portions 11a, 12a are arranged in contact, thus providing a spacer function that ensures the sealing space SS.
    [063] Comparatively, in the structure that joins the weak junction portions 84, as shown in Figure 10, the strong adhesive sealing member 81 and the weak adhesive sealing member 82 are interposed within the SS sealing space between the respective portions of outer peripheral edges 11a, 12a. That is, the upper surface of the weak adhesive sealing member 82 that fills the recessed areas 85 is positioned on the same plane as the normal surface (the outer edge surface excluding the recessed areas 85) of the outer peripheral edge portion 11a of the lower battery box structure 11, and the strong adhesive sealing member 81 whose shape when seen in section is similar to that in the normal joined portions and in the pinned portions is interposed overlapping the upper surface of the weak adhesive sealing member 82.
    [064] In the following, the operation will be described.
    [065] The description of the operation in the pressure relief structure of the battery box installed in the vehicle of the first modality will be divided into “Operation of attaching and securing the battery box”, “Action of sealing the battery box”, and “Operation of pressure release in the battery box in times of high internal pressure ”. Battery box joining and securing operation
    [066] When joining and attaching the top cover of the top cover of the battery box 12 to the bottom structure of the battery box 11, the operation goes through: (a) a filling step with a weak adhesive seal (b) a filling step filling with strong adhesive seal (c) a spacer and clamp adjustment step (d) a step of securing the grounding pin (e) a step of securing the corner pin
    [067] In the weak adhesive seal filling step, the recessed areas 85 of the outer peripheral edge portion 11a of the lower battery box structure 11 are filled with the weak adhesive seal member 82, in amounts equal to the volume of depression of indented areas 85.
    [068] In the strong adhesive seal filling step, the strong adhesive seal member 81 is applied continuously along the outer peripheral edge portion 11a of the lower structure of the battery box 11, while maintaining a section in high built section.
    [069] In the spacer and clamp positioning step, a plurality of spaces to maintain the seal spacing within the applied strong adhesive sealing member 81 are attached, and clamps are positioned respectively in the positions where the spacers have been attached. positioned.
    [070] In the step of securing the grounding screw, the grounding screws 71 to maintain the seal spacing are secured and retained in the four corners. Through the spacer described above and the step of adjusting the clamp and the step of securing the grounding pin, a constant sealing spacing is maintained around the entire perimeter of the case.
    [071] In the step of securing the corner screw, after waiting for the strong adhesive seal member 81 and the weak adhesive seal member 82 to heal to a certain point while maintaining constant seal spacing around the entire perimeter of the case, the clips are removed, and the six corner pins 72 are secured and secured.
    [072] Consequently, the strong adhesive sealing member 81 is constructed in such a way that it has a fixed width and thickness around the entire perimeter, and the weak adhesive sealing member 82 is treated in such a way that its upper surface is on the same plane as the normal surface of the outer peripheral edge portion 11a of the bottom structure of the battery box 11. Sealing the battery case
    [073] The BP battery box, which is installed below the floor of the vehicle body, is subject to warned environmental conditions and charging conditions, and it is necessary to ensure sufficient strength to overcome these conditions. A battery box sealing action reflecting this is described below.
    [074] In the first modality, a constitution was adopted for the sealing members by nailing the strong adhesive sealing member 81 and the weak adhesive sealing member 82 made of a urethane-based adhesive having adhesive strength meeting certain environmental conditions and informed loading conditions (Figures 7-10).
    [075] Therefore, in normal moments, in the absence of internal pressure, the adhesive sealing members 81, 82, because they have an adhesive resistance that is sufficient only to reach selected environmental conditions, inhibit the infiltration of water into the interior of the case chamber during car wash with high pressure or travel on flooded roads, and ensure the water impermeability inside the case chamber. In addition, an air tightness is ensured so that the interior of the chamber is maintained in an airtight state despite fluctuations in the internal pressure of the case within a predetermined range due to changes in the external temperature of the case. air or internal temperature of the case. In addition, adhesive sealing members 81, 82, because they have sufficient adhesive strength only to meet the selected informed loading conditions, inhibit the occurrence of seal breakage or seal breakage in response to frontal impact or side impact information. , or vibration information coming from the road surface or similar, and ensure the resistance of the vehicle. Specifically, the required sealing performance of the BP battery box that will be installed below the floor of the vehicle body is ensured.
    [076] Normally, a gasket is employed as the part arranged between two case members to provide reliable sealing performance. However, in the case of large case parts, such as the battery case, gaskets, which are made from elastic materials, are subject to deformation during assembly, thus requiring a laborious effort to arrange the gasket in the pre-position -specified, and decreasing the ease of the joining procedure. In addition, it is necessary to prepare large gaskets from which defects have been eliminated through quality control in order to provide a reliable seal around the entire perimeter, and this leads to an increased cost.
    [077] In comparison, in the case of adhesive sealing members 81, 82, the sealing members can be arranged through the filling procedure of the weak adhesive sealing member 82 and the procedure of applying the strong adhesive sealing member 81 as described above, and therefore the efficiency of the joining procedure is higher than with gaskets. In addition, it is sufficient to prepare just one urethane-based adhesive in a container for the procedure, and since a liquid adhesive can be used without waste, the cost is lower than with gaskets.
    [078] In the first embodiment, the adhesive seal members are formed by the strong adhesive seal member 81, and the weak adhesive seal member 82 having a lower adhesive resistance than the strong adhesive seal member 81. A constitution is adopted in which the recessed areas 85 provided in the areas corresponding to the deformable stepped portions 83 in the outer peripheral edge portion 11a of the lower battery box structure 11 are filled by the weak adhesive sealing member 82, and the strong adhesive sealing member 81 is interposed from continuously around the entire perimeter along the outer peripheral edge portion 11a, including the recessed areas 85 (Figure 5).
    [079] Specifically, by interposing the strong adhesive sealing member 81 continuously around the entire perimeter of the outer peripheral edge portion 11a of the lower battery box structure 11, variations in water impermeability and performance in terms of Informed strength is minimized around the entire perimeter where the seal is interposed, and the required sealing performance described above is ensured. As shown in Figure 10, a constitution is adopted for the joints in the recessed areas 85 in which the strong adhesive seal member 81 overlaps the weak adhesive seal member 82 located on the underside, and the weak joint portion 84 is positioned by this section.
    [080] Consequently, by using, as adhesive sealing members, the strong adhesive sealing member 81 for the entire perimeter and the weak adhesive sealing member 82 which is partially overlapped by the strong adhesive sealing member 81, it is possible to both ensure the sealing performance required when adjusting the weak junction 84.
    [081] In the first embodiment, a configuration is adopted in which the upper surface of the weak adhesive sealing member 82 that fills the recessed areas 85 is positioned on the same plane as the normal surface of the outer peripheral edge portion 11a of the structure bottom of battery box 11 (Figure 10).
    [082] Consequently, the strong adhesive sealing member 81, which has a consistent cut shape, can be interposed continuously around the entire perimeter of the outer peripheral edge portion 11a of the lower structure peripheral edge of the structure bottom of battery box 11, to create a uniform water-impermeable performance and reported resistance performance, and to ensure the required sealing performance. Pressure release operation in the battery box in times of high internal pressure
    [083] In the manner described above, although sealing performance is required under normal circumstances, when the internal pressure has risen due to the production of gases inside the case, a phase function is required whereby the sealing function is interrupted, and the internal gases are discharged to the outside of the case. A pressure release operation from the battery case in moments reflecting this is described below based on Figures 11 and 12.
    [084] In the first embodiment, the top cover of the battery box 12 is provided with the deformable stepped portions 83 having a height difference in the vertical direction. Within the adhesive sealing members 81, 82 that extend continuously around the entire perimeter, the weak junction portions 84 of lesser resistance than other joined portions are positioned in areas that correspond to the deformable stepped portions 83 (Figure 6).
    [085] Consequently, when gases are produced by the battery module 2 disposed inside the case chamber, and the internal pressure of the case chamber increases, the internal pressure is concentrated on sections of the case of the case structure that protrude even further. to the center of the case within the case structure, i.e., the deformable stepped portions 83 of the upper battery box cover 12, as shown by the arrow G in Figure 11.
    [086] The reason why the internal pressure is concentrated in the deformable scaled portions 83 will now be described in detail. It is assumed that, when the pressure of confined gases inside increases, the pressure (internal pressure) that affects the internal surfaces of the case is constant for all internal surfaces of the case. That is, in an extreme scenario, pressure acts to transform the case into a sphere (all internal surfaces are at the same distance from the center when transformed into a sphere). However, as the stiffness of the foam is not so low as to allow transformation into a sphere by such internal pressures, the deformation does not exceed a small level at which the basic shape is maintained. Therefore, sections that do not approach a sphere (sections that differ greatly from internal surfaces of a hypothetical case located at the same distance from a hypothetical center when the case is transformed into a sphere) are subjected to lower pressures. In fact, as the shape of the case is complex, the pressure distribution is also complex, but in terms of the general concept, the distribution is no different from one in which sections do not approach a sphere and are compressed more tightly . This action of pressing hard is called the concentration of internal tension. Thus, the internal tension is concentrated in the deformed staggered portions 83, which are sections that are recessed towards the central side (the inside side) of the case (or, to put it another way, that extend towards the side of the case). center).
    [087] Due to this concentration of internal tension, the upper cover of the battery box 12 undergoes deformation in a direction of reducing the height difference in the vertical direction of the step in the deformable staggered portions 83 (the direction of the hypothetical line shown by H in Figure 11), that is, from the lowest step in the direction of the highest step in the vertical direction. Due to this deformation of the cover, the joint of the weakly connected portion 84 that was positioned in the area corresponding to the deformable stepped portion 83 opens, the outer peripheral edge portion 12a of the upper cover of the battery box 12 (the upper cover after deformation in Figure 11) separates from the outer peripheral edge portion 11a of the lower battery box structure 11, and an opening I forms in the weak junction portion 84. Therefore, when the internal pressure of the case chamber has risen due to the production of gases, the internal gases are discharged out through the opening I of the weak junction portion 84 as shown by the arrow J in Figure 12, without inducing the rupture or breaking of the upper battery box cover 12.
    [088] Thus, the internal pressure concentrated in the deformable staggered portion 83 of the upper cover of the battery box 12 induces the deformation of the cover, the weak junction portion 84 opens, forming the opening I through which the case chamber communicates with the outside air. For that reason, when the internal pressure of the case chamber has risen due to the production of gases, the internal gases can be discharged to the outside through the separable opening of the weak junction portion 84.
    [089] In the first embodiment, the first flat portion 12b, the second flat portion 12c, the first inclined surface 12c, the third flat portion 12e, and the second inclined surface 12f are formed in the upper surface sections of the top cover of battery box 12, and the left side slope 12g and the right side slope 12h are formed in left and right side surface sections. A constitution in which the deformable stepped portions 83 are formed by the first edge line 83a, the second edge line 83b, the third edge line 83c, the fourth edge line 83d, and the fifth edge line 83e on which upper surface sections and the crossing of left and right surface sections is adopted (Figure 4).
    [090] Specifically, the deformable stepped portion 83 is a section in which the second edge line 83b, the third edge line 83c, and the fourth edge line 83d enter in the downward direction of the vehicle with respect to a line connecting a end of the first edge line 83a and an end of the fifth edge line 83e as shown by H in Figure 11, the deformable stepped portion 83 projecting further towards the center of the case in the case structure. Therefore, when the internal pressure in the case chamber has risen, the internal pressure is concentrated on the second edge line 83b, the third edge line 83c, and the fourth edge line 83d entering through the downward direction of the vehicle. Due to this concentration of internal pressure, the top cover of the battery box 12 undergoes considerable deformation in order to eliminate the degree to which the second edge line 83b, the third edge line 83c, and the fourth edge line 83d which they enter by the downward direction of the vehicle.
    [091] Therefore, when forming the deformable staggered portions 83 that undergo considerable deformation of the lid in response to an increase in the internal pressure in the case chamber, when the internal pressure of the case chamber increases due to the production of gases, the pressure is reliably released from the weakly joined portions 84 due to deformation of the lid.
    [092] The first flat portion 12b, the second flat portion 12c, and the first inclined surface 12d are formed in upper surface sections of the upper cover of the battery case 12, and the left-side sloping surface 12g and the side-sloping surface 12 o'clock on the right are formed in surface sections on the left and on the right. The deformable stepped portions 83 can be formed by the first edge line 83a, second edge line 83b, and third edge line 83c, in which the upper surface sections and the left and right surface sections intersect.
    [093] In this case, the deformation of the top cover of the battery box 12 due to the concentration of internal stress would be caused in a direction that extends to the polygonal line angle of the first edge line 83a and the second edge line 83b, and the angle polygonal line of the second edge line 83b, and the third edge line 83c.
    [094] Therefore, when forming the deformable stepped portions 83 which are subjected to sufficient cover deformation in response to an increase in the internal pressure in the case chamber, when the internal pressure of the case chamber increases due to production of gases, pressure is released from the weak junction portions 84 due to deformation of the cap.
    [095] Advantageous effects are described below.
    [096] The advantageous effects mentioned below can be obtained with the pressure release structure of the battery box installed in the vehicle of the first modality.
    [097] (1) A battery box installed in a vehicle in which a battery box case 1 includes a lower battery box structure 11 and an upper battery box cover 12, a battery box module 2 being arranged on the lower battery box structure 1, where the upper battery box cover 12 is securely joined on the lower battery box structure 11 by a sealing member (a strong adhesive sealing member 81 and a weak adhesive sealing member 82) extending continuously around the entire perimeter of respective outer peripheral edge portions 11a, 12a; the upper lid of the battery box 12 is provided with a deformable stepped portion 83 having a height difference at least in the vertical direction; and 59.4 a weak joint portion 84 with less joint strength than other joined portions is positioned in an area of the sealing member (a strong adhesive sealing member 81 and a weak adhesive sealing member 82) that extends continuously in around the entire perimeter, the area corresponding to the deformable staggered portion 83 (Figure 6).
    [098] Thus, the constitution is such that the internal pressure concentrated in the deformable staggered portion of the upper cover of the battery box 12 induces the deformation of the upper cover of the battery box 12, and, in association with the deformation, When the lid is removed, the weak junction portion 84 opens, forming the opening I through which the case chamber communicates with the outside air. For this reason, when the internal pressure of the case chamber has risen due to the production of gases, the internal gases can be discharged outwardly through the separable opening of the weak junction 84.
    [099] (2) A first flat portion 12b, a second flat portion 12c less than that of the first flat portion 12b, and a first inclined surface 12d connecting the first flat portion 12b and the second flat portion 12c are formed. in the upper surface sections of the upper battery box cover 12, a left-facing side surface 12g and a right-facing side surface 12h extending diagonally downwardly from end portions transversely to the vehicle of the first flat portion 12b, the second flat portion 12c, and the first inclined surface 12d are formed into surface sections to the left and right of the upper battery box lid 12, and the deformable stepped portion 83 is formed so as to have a first line of edge 83a on which the left and right sloping side surfaces 12g, 12h and the first flat portion 12b intersect, and a third edge line 83c on which the sloping side surfaces left and right 12g, 12h and the second flat portion 12c intersect (Figure 4).
    [0100] Therefore, in addition to the advantageous effect of (1), by the formation of the deformable stepped portion 83 which is subject to sufficient cover deformation in response to an increase in the internal pressure in the case chamber, when the internal pressure of the case chamber increases due to gas production, pressure can be released from the weak junction portion 84 due to deformation of the cap.
    [0101] (3) A third flat portion 12e which is lower than the first flat portion 12b, but higher than the second flat portion 12c, and a second inclined surface 12f connecting the third flat portion 12e and the second flat portion 12c , are added to upper surface sections of the upper cover of the battery box 12, and 61.1 the deformable stepped portion 83 is formed while being added to the first edge portion 83a, the second edge portion 83b, and the third edge portion 83c, a fourth edge portion 83d on which left and right angled side surfaces 12g, 12h and the second angled surface 12f intersect, and a fifth edge line 83e on which angled left and right side surfaces 12g, 12h and the third flat portion 12e intersect (Figure 4).
    [0102] Therefore, in addition to the advantageous effect of (2), by increasing the deformation capacity of the cover by the deformable stepped portion 83, when the internal pressure of the housing chamber has increased due to the production of gases, the pressure can be released of the weak junction portion 84 by deforming the lid, with good response and reliably.
    [0103] (4) Adhesive seal member (a strong adhesive seal member 81 and a weak adhesive seal member 82) made of a urethane-based adhesive having an adhesive resistance that meets the environmental conditions and reported loading conditions are used as the sealing members (Figures 7 - 10).
    [0104] Therefore, in addition to the advantageous effects of (1) - (3), the required sealing performance of the BP battery box can be ensured, and, additionally, compared to the case of using a gasket as a sealing member, the the joining procedure is easier, and a reduction in costs can be achieved.
    [0105] (5) The adhesive sealing member includes a strong adhesive sealing member 81, and a weak adhesive sealing member 82 having less adhesive strength less than the strong adhesive sealing member 81, a recessed area 85 provided in an area corresponding to the deformable stepped portion 83 within an outer peripheral edge portion 11a of the lower battery box structure 11 is filled by the weak adhesive seal member 82, and a strong adhesive seal member 81 is continuously interposed around the entire perimeter along the peripheral edge portion 11a, including the recessed area 85, of the lower battery box structure 11 (Figure 5).
    [0106] In this way, using the strong adhesive seal member 81 around the entire perimeter, and the weak adhesive seal member 82 that partially overlaps the strong adhesive seal member 81, as adhesive seal members, in addition from the advantageous effect of (4), the required sealing performance can be ensured, at the same time as the weak junction portions 84 are positioned.
    [0107] (6) An upper surface of the weak adhesive seal member 82 filling the recessed area 85 is positioned on the same plane as a normal surface of the outer peripheral edge portion 11a of the lower battery box structure 11 (Figure 10).
    [0108] Therefore, in addition to the advantageous effect of (5), the sealing performance can be made uniform around the entire perimeter where the sealing is interposed, and the required sealing performance can be ensured.
    [0109] Although the pressure release structure for a battery box installed in the vehicle of the present invention has been described above based on the first modality, the specific constitution is not limited to that of the first modality, and several design modifications and additions to the even are acceptable within the scope of the invention as described in the claims.
    [0110] In the first embodiment, an example was shown in which the deformable staggered portions 83 are formed by the first edge line 83a, by the second edge line 83b, by the third edge line 83c, by the fourth edge line 83d, by the fifth edge line 83c, in which surface sections to the left and right of edge lines and upper surface sections of the battery box top cover 12 intersect. However, an example in which the deformable scaled portions are formed, for example, by a first edge line, a second edge line, and a third edge line, edge lines in which sections of the left side surface and to the right and upper surface sections of the top cover of the battery box intersect, would be acceptable as well. Specifically, considering that the deformable staggered portion is a structure made up of a section having a height difference at least in the vertical direction, and is adapted to induce deformation of the upper cover of the battery box when the internal pressure of the chamber increases and the internal pressure if it becomes concentrated, its specific format is not limited to that of the first modality.
    [0111] In the first embodiment, an example has been shown in which the strong adhesive sealing member 81 and the weak adhesive sealing member 82 made of a urethane based adhesive are employed as sealing members. However, it would be acceptable to use a gasket sealing member, or a combination of gasket sealing member and adhesive sealing member, as sealing members, and the specific material for the sealing members is not limited to the adhesive based in urethane of the first modality.
    [0112] In the first embodiment, an example was shown in which the weak junction portions 84 are positioned within the strong adhesive sealing member 81 that extends continuously around the entire perimeter, by overlapping the weak adhesive sealing member 82 in the even in partial areas corresponding to the deformable stepped portions 83. However, depending on the material, combination, and the like of the sealing member, the specific way in which the weak junction portions are positioned is not limited to that of the first modality. provided that sections with lower adhesive strength than other sections are determined as the weak junction portions.
    [0113] In the first embodiment, an example was shown in which the pressure release structure of the present invention is applied to a minivan-type electric car having a propulsion engine as the only propulsion energy source. However, the pressure release structure for a vehicle-mounted battery box of the present invention can naturally be applied to electric cars of various types in addition to the minivan type, such as sedan type, wagon type, SUV type, or the like. The structure can also be applied to hybrid vehicles having a propulsion engine and an onboard engine as power sources for propulsion. That is, the structure can be applied to any battery box installed in an electric vehicle. References to Related Orders
