    [0002] Coupling device
    [0004] Object of the invention
    [0006] The subject of the present invention is a coupling device. More particularly, the present invention can be applied to the coupling of a vehicle accessory (such as a pilot light) to a structural element or sheet metal of the vehicle.
    [0008] The coupling device object of the present invention allows the accessory to be coupled to a sheet metal of the vehicle in a simple and reliable way, and which ensures the absorption of the dimensional tolerances of the elements that intervene in said coupling.
    [0010] The coupling device object of the present invention has special application in the field of the automobile industry and, more specifically, in the field of accessories that are fixed to the body of a vehicle, such as exterior lighting devices that a vehicle incorporates. .
    [0012] Background of the invention and technical problem to be solved
    [0014] In a vehicle there are many elements and accessories that must be attached to a structural element, by fixing a bolt or projection of the accessory housing to a hole in the structural element.
    [0016] An example is the attachment of the front or rear indicator lights to the vehicle. The pilot lights comprise a casing from which two or more bolts usually come out for fixing to a structural element or plate located in a housing in the body or under the body of the vehicle.
    [0018] Traditionally, the bolt is inserted into a hole in the sheet metal and fixed by means of fastening.
    [0019] The problem appears when, due to inaccuracies (which in many cases are unavoidable) in the manufacturing process, the manufactured elements (bolts, housings, etc.) do not have the exact design measurements, but instead have dimensional tolerances. These tolerances can cause the accessories to be installed in the vehicle not fitting correctly, presenting deviations in the axes of the bolt, or deviations in size or position, which can cause the elements to have to fit in a forced way in the sheet or structural element of the vehicle. This forced fit can end up producing vibrations or even cracks and breaks in the elements of the vehicle and / or in the accessory installed in the vehicle.
    [0021] Description of the invention
    [0023] In order to solve the aforementioned drawbacks, the present invention relates to a device for coupling to a structural element.
    [0025] Said structural element is typically a sheet metal, and preferably a sheet metal of a vehicle. Thus, the coupling device makes it possible to retain a third component to the sheet. Advantageously, the present invention makes it possible to absorb or compensate for tolerances in the aforementioned retention of the third component to the sheet. The tolerances are the result of the dimensional variabilities of the production processes, the dimensional variabilities that are introduced in the assembly and fixation of the parts, which can make these parts not fit correctly in the conventional assembly processes. In order to guarantee a correct nominal position between the different parts, it is necessary to absorb or compensate for these tolerances.
    [0027] The coupling device makes it possible to couple a fixing bolt (for example, one of the bolts of the housing of a vehicle light) to the structural element, through the coupling device.
    [0029] The coupling device comprises a main body. Said main body in turn comprises:
    [0031] - a cap, where the cap generates a hollow space, with at least one side wall, where the hollow space is suitable to receive the fixing bolt; the geometry of the cap can be with a single curved surface or revolution, either prismatic or truncated-pyramidal with a plurality of side walls, defining said hollow space;
    [0033] - a base located at a first end of the cap, where the base defines an opening suitable for receiving the fixing bolt in the hollow space of the main body;
    [0035] - fixing means suitable for fixing the coupling device to the structural element;
    [0037] - Retaining means, arranged on the inner surface of the side wall, where the retaining means are able to retain the fixing bolt in the cap, once said fixing bolt has been inserted into the hollow space generated by the cap.
    [0039] The main body is formed of plastic material and comprises means for compensating tolerances, said means being substantially deformable, in such a way as to make it possible to adjust at least one dimension in the mounting of the fixing bolt with respect to the structural element.
    [0041] By cap is understood the part of the main body formed by a single piece of deformable plastic material or rubber, which generates the hollow space destined to house the bolt.
    [0043] The at least one side wall of the cap connects the first end of the cap with a second end end of the cap.
    [0045] The tolerance compensating means allows a longitudinal or transverse dimension to be adjusted in the mounting of the fixing bolt.
    [0047] The different elements that intervene in the assembly (pilot light housing, housing bolt, sheet metal or structural element, hole in the sheet, etc.) have dimensions manufactured with certain degrees of tolerance, in such a way that, in the at the time of assembly, it may happen that the elements do not fit with all the slack or separation that would be desirable between the different elements. This can make the assembly process difficult, causing the elements to be forced against each other, and even causing deviations at the time of fitting some elements with each other. This generates an aesthetic and even structural problem, due to poorly absorbed vibrations that can occur while driving the vehicle, and that could lead to cracks in the elements that intervene in the assembly.
    [0049] By means of the coupling device object of the present invention, these tolerances are allowed to be absorbed, both in a transverse axis (Y or Z) and in a longitudinal axis (X) of the bolt and of the device, by means of the controlled deformation of the means. tolerance compensation, while allowing the bolt to be retained in the coupling device and thus retaining the casing to the structural member.
    [0051] Preferably, the base of the main body comprises a lip arranged on the perimeter of said base. This lip is substantially deformable and is configured to contact a surface of the structural element (typically with a surface surrounding a hole in the sheet or structural element). This lip makes it possible to provide sealing at the junction between the coupling device and the structural element, by means of a contact around the entire perimeter of the base.
    [0053] According to a possible embodiment of the invention, the retaining means comprise at least one projection, wherein said at least one projection is configured to be inserted into at least one corresponding recess of the bolt. Alternatively, the retaining means could comprise at least one recess into which at least one shoulder of the bolt would be inserted.
    [0055] By means of these retaining means, a correct longitudinal fixation of the bolt in the device is ensured, preventing the bolt from accidentally coming out through the opening of the cap.
    [0057] According to a first embodiment of the coupling device, which does not form part of the invention, the tolerance compensation means are arranged connecting the at least one side wall of the cap with the base, where the tolerance compensation means comprise a plurality of folds distributed in an annular manner in the at least one side wall of the cap, in transverse planes of the cap, as one advances in the longitudinal direction from the first end, where the base of the main body is located, to the second terminal end of the cap. These folds thus build a geometry in the shape of an accordion or bellows, which makes it possible to absorb longitudinal and transverse tolerances.
    [0059] Preferably, the pleats comprise a greater thickness in the zones substantially perpendicular to the longitudinal direction than the thickness of the zones substantially parallel to said longitudinal direction. In this way, the side wall is reinforced in those areas most susceptible to being stretched when tolerances are absorbed during assembly, facilitating a transverse deformation of the tolerance compensation means and hindering a longitudinal deformation thereof. By regulating the thickness and / or the material of the tolerance compensation means, its deformation capacity is regulated and, therefore, the adjustability of the at least one dimension or dimension in the mounting of the fixing bolt with respect to the structural element.
    [0061] Preferably, according to the first embodiment of the coupling device, the device is obtained by a single injection process, consisting of a deformable soft plastic or rubber.
    [0063] Preferably, according to this first embodiment of the coupling device, the fixing means comprise a perimeter groove arranged in an outer fold of the tolerance compensation means, and where the perimeter groove of the base and the perimeter lip cooperate to fix the coupling device to the structural element or sheet. This makes it possible to facilitate the mounting of the coupling device on the sheet, adjusting to a flange or perimeter wall of the layer that defines the hole in the sheet.
    [0065] In a second embodiment of the coupling device, which does not form part of the invention, the device additionally comprises an auxiliary body made of plastic material, where the auxiliary body comprises a support, capable of being supported on the base of the main body, where The auxiliary body consists of a rigid or semi-rigid plastic that covers the second terminal end of the cap and at least a part of the at least one side wall of the cap.
    [0066] The auxiliary body is obtained through an injection process, independent of the injection process by which the main body is manufactured.
    [0068] This auxiliary body makes it possible to increase the rigidity of the coupling device, limiting the maximum deformations that the device can undergo to absorb tolerances during assembly, and also increasing the fixing action of the fixing means of the base of the device, by preventing them from may deform excessively and the device may loosen from the structural member.
    [0070] Preferably, the auxiliary body covers the main body only in one transverse direction (Y or Z), not covering the other transverse direction. By covering is meant to be arranged adjacent and parallel to the outer surface of the side walls of the cap. There may be a clearance between said outer surface of the side walls and the auxiliary body or there may be direct contact between the two, depending on whether a greater or lesser degree of tolerance compensation is desired in said transverse direction. When direct contact occurs between the outer surface of the main body side wall and the auxiliary wall, the movement of the cap is blocked. Tolerance compensation will only be carried out by deformation of the side wall, which is made of a soft plastic material.
    [0072] Preferably in this second embodiment, said auxiliary body is configured to make contact with the second terminal end of the cap and / or make contact with one or more of the recesses of the tolerance compensation means, so that the auxiliary body makes it possible to limit a displacement of the main body in the longitudinal direction.
    [0074] Initially (before mounting the bolt) there would be a certain air gap between the second terminal end and / or the recesses of the cap and the auxiliary body. After the movement of the cap at the time of mounting / inserting the bolt into the cap, the aforementioned contact would occur between the second terminal end and / or the recesses of the cap and the auxiliary body. In this way, the auxiliary body limits (but allows) a certain degree of deformation of the cap.
    [0076] Also in this second embodiment, preferably, the fixing means comprise at least one groove arranged on an outer surface of the auxiliary body, and where the at least one groove of the auxiliary body and the perimeter lip of the base cooperate to fix the coupling device to the structural element or sheet. This makes it possible to facilitate the mounting of the coupling device on the sheet, by fitting into a flange of a hole in the sheet.
    [0078] In a third embodiment of the coupling device, the tolerance compensation means do not comprise the set of tucks.
    [0080] According to this third embodiment, the coupling device comprises an auxiliary body of plastic material, where the coupling device is made by means of a bi-injection procedure, consisting of a double injection of a first plastic or soft rubber material, forming the main body, and a second rigid or semi-rigid plastic material, forming the auxiliary body, where the auxiliary body comprises a support that contacts the base of the main body, where the auxiliary body covers the second terminal end of the cap and at the least a part of the at least one side wall of the cap.
    [0082] According to this third embodiment of the coupling device, the tolerance compensation means are arranged on the at least one side wall of the cap that defines the hollow space, where said side wall is made of soft plastic or rubber material and is capable of deformation. by a pressure exerted by the fixing bolt, said deformation being limited by the rigid or semi-rigid plastic of the auxiliary body that covers the side wall of the cap.
    [0084] Thus, both the hardness of the material of the main body and its thickness define the degree of adjustment of the at least one dimension in the mounting of the fixing bolt with respect to the structural element. Additionally, in order to control the maximum deformation and, therefore, the maximum desirable tolerance in the joint between both components, the auxiliary body made of rigid material contacts the main body, defining said position. As mentioned above, the coating only occurs between the auxiliary body and the outer surface of the main body in a transverse direction.
    [0086] Also according to this third embodiment, preferably the fixing means comprise at least one groove arranged on an outer surface of the auxiliary body, and where the at least one groove of the auxiliary body and the perimeter lip of the base cooperate to fix the coupling device to the structural element or sheet. This makes it possible to facilitate the mounting of the coupling device on the sheet, by fitting into a flange of a hole in the sheet.
    [0088] The present invention also refers to a motor vehicle that comprises at least one lighting module, where the lighting module (or pilot light) comprises at least one fixing bolt to a structural element (or sheet metal) of the vehicle, where the at at least one fixing bolt is retained to the structural element of the vehicle by means of at least one coupling device as described above according to any of the indicated embodiments, and where the cap of the coupling device is configured to be inserted into a hole of the structural element and to be fixed to a flange of said hole by means of the fixing means, where the coupling device makes it possible to adjust at least one dimension in the mounting of the fixing bolt with respect to the structural element, by means of the compensation means of substantially deformable tolerances.

    [0109] Detailed description
    [0111] The present invention relates, as mentioned above, to a coupling device (100), more specifically, a coupling device (100) to a structural element (300), and more specifically, a device (100) for coupling a fixing bolt (200) to a structural element (300).
    [0113] The device (100) makes it possible to couple and mount, by way of example, a pilot light of a vehicle to a structural element (300) or mounting plate of the vehicle.
    [0115] The coupling device (100) comprises a main body with a cap (101) or cap, configured to receive a bolt (200) from the pilot light housing.
    [0117] The main body comprises fixing means (102) to the structural element (300) or plate of the vehicle.
    [0119] Specifically, the cap (101) is configured to be arranged in a hole (301) of the structural element (300) or plate of the vehicle, and the fixing means (102) are configured to allow the cap (101) to be fixed to the edge of said hole (301) of the structural element (300) or sheet of the vehicle. The cap (101) comprises a side wall (104).
    [0121] The main body of the device (100) comprises a base (105) located in correspondence with a first end (106) of the cap (101). The fixing means (102) may be located at the base (105) of the main body.
    [0122] In correspondence with the first end (106) of the cap (101) there is an opening (108) configured to receive the fixing bolt (200). The cap (101) also comprises a second terminal end (107) opposite the first end (106). Preferably, the second terminal end (107) is closed.
    [0124] Thus, the cap (101) is configured to be inserted into said hole (301) of the structural element (300) or sheet and receive, through the opening (108) and in correspondence with the inner or concave surface (inner surface from the side wall (104)) of the cap (101), to the fixing bolt (200).
    [0126] The main body of the device comprises retaining means (109) arranged on the inner surface of the side wall (104). These retaining means (109) allow to retain the bolt (200) inside the cap (101).
    [0128] Preferably, the retaining means (109) comprise an internal projection of the cap (101), where said projection is configured to be inserted into a corresponding recess (201) existing in the bolt (200). This internal projection allows that, once the bolt (200) has been inserted into the cap (101), the bolt (200) is retained inside the cap (101) preventing its longitudinal movement out of the cap (101).
    [0130] The main body comprises tolerance compensation means (110), these tolerance compensation means being substantially deformable, to allow absorbing the manufacturing tolerances of the bolt (200) and of the structural element (300), thus allowing to adjust at least one dimension in the mounting of the bolt (200) with respect to the structural element (300).
    [0132] The tolerance compensation means (110) can allow to absorb dimensional tolerances in the longitudinal direction of the bolt (200) and of the cap (101) (along the X axis), or in any of the transverse directions of the bolt (200) and of the cap (101) (Y axis or Z axis), as explained below.
    [0134] According to a first embodiment of the device (100) shown in Figure 1 and Figure 2, which does not form part of the invention, the tolerance compensation means (110) comprise a set of folds distributed in an annular manner on the side wall of the cap (101), in transverse planes of the cap (101).
    [0136] According to a second embodiment of the device (100) shown in Figure 3, Figure 4 and Figure 5, which does not form part of the invention, the tolerance compensation means (110) also comprise said set of folds.
    [0138] These folds form a geometry that resembles the geometry of a bellows or accordion. By means of this bellows structure, if the inserted bolt (200) is not perfectly aligned with the longitudinal axis (X axis) of the cap (101), the tolerance compensation means (110) allow its position to be adjusted to ensure correct positioning of the mounting between the bolt (200) and the structural element (300).
    [0140] Thus, there are three cases where the mounting of the fixing bolt (200) with respect to the structural element (300) is not optimal, so that it is necessary to adjust a transverse dimension by means of the tolerance compensation means (110):
    [0142] a) longitudinal axis (X axis) of the bolt is not parallel to the longitudinal axis (X axis) of the cap (101), that is, there is a misalignment between axes. To compensate for said alignment deficiency and adjust the transverse mounting dimensions between both components, the lower zone of the tolerance compensation means (110) contracts and the upper zone extends (and vice versa at the opposite transverse end of the tolerance compensation means). tolerances (110)) according to the direction of said misalignment.
    [0143] b) longitudinal axis (X axis) of the bolt is parallel to the longitudinal axis (X axis) of the cap (101) but they are not coincident. Thus, to compensate for said displacement, a first end of the tolerance compensating means (110) is compressed, with less distance between the pleats, and the second end opposite the first end in the transverse direction extends, widening the distance between the pleats. .
    [0144] c) Combination of both cases previously exposed.
    [0145] The base (105) of the main body comprises a perimeter contour or lip (111), made of soft material. Said perimeter lip (111) is configured to completely cover the perimeter edge of the hole (301) of the structural element (300) or sheet, ensuring a perfect seal that prevents the passage of water or other liquids between the structural element (300) or sheet metal and the perimeter lip (111).
    [0147] In both the first and second embodiments, the cap (101) of the coupling device (100) is obtained with a single injection process, consisting of a deformable soft plastic or rubber.
    [0149] The folds that make up the tolerance compensation means (110) have greater thickness in the areas perpendicular to the longitudinal direction (direction along the X axis), thus seeking greater ease of movement of the cap (101) in transverse directions (Y or Z) and a greater difficulty of movement of the cap (101) in a longitudinal direction (Z).
    [0151] The perimeter lip (111) is configured to be arranged on the rim of the hole (301) of the structural element (300) or plate, in correspondence with a first side (or outer side) of the structural element (300) or plate. The rest of the volume of the cap (101) is configured to be inserted in the hole (301) and protrude through a second side (or inner side) of the structural element (300) or sheet.
    [0153] According to the first and second embodiments of the coupling device (100), the fixing means (102) comprise a perimeter groove (103) arranged in an outer recess of the tolerance compensation means (110). This perimeter groove (103) is located in correspondence with the base (105) of the main body and cooperates with said perimeter lip (111) to fix the coupling device (100) to the structural element (300) or sheet.
    [0155] Thus, the perimeter lip (111) is configured to be on the first side (or outer side) of the structural element (300) or plate, while the edge of the hole (301) of the structural element (300) or plate remains inserted into the slot (103).
    [0157] According to the second embodiment of the coupling device (100) shown in Figure 3, Figure 4 and Figure 5, the device (100) comprises a body auxiliary (112) of rigid or semi-rigid plastic material. This auxiliary body (112) has a support (113) located on the base (105) of the main body, and has an area that covers the second end (107) of the cap (101), and another area that covers a part of the side wall (104) of the cap (101).
    [0159] This auxiliary body (112) of the second embodiment of the device (100) is manufactured according to an injection process independent of the injection process of the cap (101).
    [0161] Preferably, the auxiliary body (112) of the second embodiment of the coupling device (100) is configured to contact the second end end (107) of the cap (101) and / or with one or more of the pleats of the tolerance compensation means (110). This contact takes place before the deformation that the cap (101) undergoes by the introduction of the bolt (200) and the absorption of dimensional tolerances, in such a way that the auxiliary body (112) limits the maximum deformation that the cap (101 ) at those points of contact. Thus, the introduction of the bolt (200) in the hollow space defined by the cap (101) in the longitudinal direction (X) tends to move the cap (101) in said longitudinal direction (X), especially in the contact of the bolt ( 200) with the retaining means (109), and especially when the bolt (200) is not in its nominal mounting position with respect to the cap (101). Thus, said pressure exerted by the bolt (200) to the cap (101) tends to undo the folds of the tolerance compensation means (110). Thus, the auxiliary body (112) contacts the main body limiting said displacement, thus allowing a tolerance compensation in the Z axis but guaranteeing the correct operation of the tolerance compensation means (110).
    [0163] Preferably, the auxiliary body 112 of the second embodiment of the coupling device 100 covers the main body laterally, especially in a transverse direction. In the example shown in figure 3, the auxiliary body (112) covers the main body essentially in the Z direction. Thus, the maximum displacement of the tolerance compensation means (110) in said transverse direction is limited, thus limiting the maximum displacement of the cap (101) in said direction. Thus, a maximum dimensional fit in the transverse direction is established in the mounting of the fixing bolt (200) with respect to the structural element (300).
    [0164] According to a third embodiment of the coupling device (100) shown in Figure 6, Figure 7 and Figure 8, the tolerance compensation means (110) do not comprise the set of tucks.
    [0166] In the third embodiment, the tolerance compensation means (110) consist of the side wall (104) of the cap (101) itself. Thus, the choice of the soft and deformable material that constitutes the side walls of the cap (101) and its thickness define the deformation capacity of the tolerance compensation means (110). Thus, when the longitudinal axis (Z axis) of the bolt is displaced or misaligned with respect to the longitudinal axis (Z axis) of the cap (101), it causes pressure and compression of the side walls of said cap (101). Said deformation makes it possible to adjust the dimension in the mounting of the fixing bolt (200) with respect to the structural element (300). The existence of the auxiliary body (112) in contact with the outer surfaces of the side walls of the main body (covering the side walls in the transverse direction Z) defines a maximum deformation of the cap (101) and, therefore, a maximum compensation in said transverse direction.
    [0168] Furthermore, according to this third embodiment of the coupling device (100), the device (100) comprises an auxiliary body (112) made of rigid or semi-rigid plastic material. In this third embodiment, the coupling device (100) is made in a single bi-injection process, consisting of a double injection of a first plastic or soft rubber forming the cap (101) of the main body, and a second rigid plastic or semi-rigid forming the auxiliary body (112).
    [0170] According to this third embodiment of the invention, the auxiliary body (112) has a support (113) that contacts the base (105) of the main body, the auxiliary body (112) covering the second end (107) of the cap (101) and at least a part of the side wall (104) of the cap.
    [0172] In the third embodiment, it is observed how the bolt (200) is inserted into the cap (101) in a tight manner (see Figure 8) in one of the transverse directions (along the Z axis in correspondence with the auxiliary body), and is loose (see Figure 7) in the other transverse direction (along the Y axis) as well as in the longitudinal direction (along the X axis). The auxiliary body (112) limits the deformation of the main body in the direction transverse along the Z axis, ensuring that the retaining means (109) retain the fixing bolt (200) in the cap (101).
    [0174] Also according to this third embodiment, the fixing means (102) comprise a perimeter groove (103) arranged on an outer surface of the auxiliary body (112). This perimeter groove (103) is located in correspondence with the base (105) of the main body and cooperates with the perimeter lip (111) to fix the coupling device (100) to the structural element (300) or plate.
    [0176] According to the third embodiment, the fixing means (102) are located in the auxiliary body, in correspondence with the base (105) of the main body, and said fixing means (102) comprise a clip made of semi-rigid material, that exerts a certain resistance when the cap (101) is inserted through the hole (301) of the structural element (300) or sheet. However, once said deformed resistance of the clip for the introduction of the cap (101) has been overcome, the clip recovers its initial geometry, protruding outside the edge of the hole (301), in correspondence with the second side (inner side) of the element. structural (300) or sheet metal. This arrangement of the clip prevents the cap (101) from coming out of the hole (301) of the structural element (300) or plate on the first side (outer side) of the structural element (300) or plate, where the cap ( 101) into hole (301). The perimeter lip (111) prevents the cap (101) from coming out of the hole (301) on the second side (inner side) of the structural element (300) or sheet.
