    DESCRIPTION
    System and assembly procedure between subsets of a vehicle body.
    The present invention relates to a system and an assembly method between subsets of a body of a vehicle, in particular, between a side liner and a water channel assembly of a car.
    Background of the invention
    In a vehicle many subsets of its body are assembled. One of these subsets is formed by the side linings or flanks of the vehicle with the so-called water channel. In the area adjacent to the union between both parts, the existence of internal reinforcements that allow stiffening of specific and specific areas of the vehicle is common. By way of example, a type of reinforcement common in these areas is the reinforcement of a gas spring, a gas spring being the component that assists in the maneuver of opening and closing the tailgate of the vehicle. As a clarification, the present invention focuses on resolving the joint and coupling in the rear area of the vehicle, to the sides of the vehicle's gate. Specifically, the area of interference between the outer side lining, the gate's water channel and the reinforcement that stiffens the point of attachment of the gate's gas spring to the water channel.
    In this area it is also usual to place a trim element, usually plastic, that is housed in a cavity or housing made in the side lining of the vehicle body.
    Document FR2675107 describes a gas spring reinforcement located in the area of the water channel and joined by welding points. This reinforcement is seen in the area of the water channel, and can be dangerous for the user and favoring the accumulation of dirt in the area of the water channel, which is not desired.
    Therefore, an objective of the present invention is to provide an assembly system between subsets of a vehicle body, in particular, between a side liner and a car waterway assembly, which increases stiffness and reinforces the coupling area of the gas spring to the water channel.

    Description of the invention
    With the system they manage to solve the aforementioned problems, presenting other advantages that will be described below.
    As mentioned, the present invention focuses on resolving the interference zone between the outer side covering, the gate water channel and a reinforcement, for example a reinforcement that stiffens a point of attachment of a gas spring of a gate to the water channel. In addition, another important component is the existence of an external trim that is superimposed on the side lining. It is a trim that is adjacent to the interference zone between the side lining or flank and the gate water channel.
    This bezel is positioned in a cavity of the side liner, so that the side liner and the bezel form a substantially flush surface. The realization of this cavity or housing in the lateral lining implies that there is a zone of union or coupling between the lateral lining and the water channel assembly with a reduced surface, with a minimized overlap, which weakens the docking area of the spring of gas to the water channel.
    Thus, the assembly system between sub-assemblies of a body of a vehicle according to the present invention, where the body of the vehicle comprises a side liner and a water channel assembly of a vehicle door, where the side liner and the assembly The water channel is connected to each other, where the body comprises a reinforcing element, and where the side lining comprises a first outer surface and a second sunken surface with respect to the first surface, so that the second surface forms a concavity to accommodate a trim element, wherein the reinforcing element comprises a main body and a fin, where the main body is attached to the water channel assembly and the fin contacts the second sunken surface of the side lining.
    In this way, the reinforcement fin is a support surface and energy transmission to the lateral lining, providing a second support surface that improves the stiffness of the reinforcement.
    In addition, the first outer surface and the trim element form a surface

    substantially contiguous and flush, in order to improve the aerodynamics of the vehicle. Even so, as mentioned earlier, the need to create a cavity by drawing results in the reduction of the overlapping fins between the lateral lining and the water channel. Hence the need to increase the stiffness of the area and facilitate the union between both pieces, making use of a second support of the reinforcement to the lateral lining.
    Preferably, the fin is a surface substantially parallel to the second sunken surface, which maximizes contact between them, thus improving support and energy transmission between both components.
    In the assembly system according to the present invention, a joint between the fin of the reinforcing element and the side liner is preferably at least one weld point applied on the substantially parallel surface of the fin and on the side liner. It is thus observed that the existence of the embellishing element that covers the second sunken surface plays a prominent role since it allows that, in that determined area, the lateral lining is not seen. The fact that it is hidden is advantageous since it allows the support of second pieces and even the realization of welding points. Without the existence of trim elements covering the side lining, it would not be possible to join by welding points, since the side lining is a cosmetic piece, that is, exterior and design, so that its appearance and quality of finishes should be optimal
    According to a preferred embodiment, the main body and the fin form an angle to each other, so that a cross section of the reinforcing element is in the shape of L. For example, the angle formed between the main body and the fin is substantially perpendicular . Thus, the stiffness of the lateral reinforcement is improved by being composed of at least two surfaces that form an angle to each other. Advantageously, the thickness of the reinforcement can be reduced.
    In addition, the flap comprises a portion of the length of the reinforcing element, which is, for example, a reinforcement of a gas spring fixing area of the vehicle's gate to the vehicle body.
    In accordance with a preferred embodiment, the fixing of the gas spring to the body is through a projection of the through gas spring through a first hole of the assembly of
    5

    35
    water channel, of a second hole of the lateral lining and of a third hole of the reinforcing element, the first, second and third consecutive holes being. As can be seen, the main body of the reinforcement is the one that allows the gas spring to be attached to the body subset described. Therefore, the stress transmission is from the main body to the reinforcement fin. For this it is beneficial that the fin and main body of the reinforcement are comprised in different planes, forming an angle to each other.
    The fin is, for example, substantially in the form of a trapezoid, being joined by its parallel side greater than the rest of the reinforcing element.
    According to a second aspect, the present invention also relates to a method for an assembly between subsets of a vehicle body, where the vehicle body comprises:
    - a side covering,
    - a water channel assembly of a vehicle gate,
    - a reinforcing element, where the reinforcing element comprises a main body and a fin,
    where the procedure for assembly includes the following stages:
    - fix the main body of the reinforcement element to the water channel assembly;
    - position the lateral lining with respect to the water channel, through a support on the reinforcement element; Y
    - assemble the side lining and the water channel assembly together.
    It is thus observed that the reinforcing element acts as a positioning reference for the assembly of the side covering. Thus, the support of the lateral lining on the reinforcement element performs the pre-assembly function, so that the water channel assembly and the lateral lining are correctly positioned for final assembly.
    Advantageously, the step of fixing the main body of the reinforcement element to the water channel assembly comprises the application of at least one welding point, and additionally an adhesive can be applied.
    Furthermore, the step of positioning the lateral lining with respect to the water channel comprises applying at least one welding point on the fin of the reinforcing element and the lateral lining, preferably applying a single welding point. Thus,
    5
    10
    fifteen

    25
    30
    35
    At the end of this stage, the three components remain together. This welding point allows to have the three components pre-assembled and allows a change of work station within the assembly sequence without any movement between the pieces. Thus, the three components are positioned and prepared for the definitive union of the body subset.
    Additionally, the side covering preferably comprises a first outer surface and a second sunken surface with respect to the first outer surface, where the assembly process is characterized in that the step of assembling the side covering and the water channel assembly comprises:
    - applying at least one welding point on a first joint surface between the side lining and the water channel assembly, where the first joint surface is located adjacent to the first outer surface, and
    - Apply a joint cord on a second joint surface between the side liner and the water channel assembly, where the second joint surface is located adjacent to the second sunken surface.
    Preferably, the joint bead is a cold metal transfer welding or by applying an adhesive bead, since spot welding is not applicable to this area due to lack of overlap. As previously mentioned, the existence of a drawing in the lateral lining for the positioning of an exterior trim element implies a significant reduction of the surfaces or overlapping areas for the assembly between the lateral lining and the water channel assembly. This requires a different type of joint to the application of welding points.
    For a correct application of the joint cord, it is required that both parts be properly overlapped and in contact. The finned reinforcement of the present invention plays an important role in this section. Because the reinforcement is located in the area adjacent to said area of application of the joint cord and has already been previously attached to both the lateral liner and the water channel assembly, said reinforcement acts as a positioning element between the lateral lining and the channel channel assembly. waters, forcing its correct overlap since both components do not move during the final assembly process.
    The method according to the present invention may comprise an additional step of coupling a trim element in a concavity formed by the second

    sunken surface, so that the weld point applied to the first joint surface is hidden by an external observer.

    For a better understanding of how much has been exposed, some drawings are attached in which, schematically and only by way of non-limiting example, a practical case of realization is represented.

    Description of a preferred embodiment
    The assembly system according to the present invention serves for the assembly of a water channel assembly 1 to a side lining 2 in a vehicle.
    Figure 4 shows where the water channel 1 and the side lining 2 are placed in a vehicle.
    The side lining 2 comprises a first outer surface 22 and a second sunken surface 23, this second surface 23 defining a housing or concavity for receiving a trim element (not shown in the figures) which, for example, is made of plastic material. Due to the creation of said concavity in an area close to the
    5
    10
    fifteen
    twenty
    25
    30
    35
    overlap zone between the side lining 2 and the water channel assembly 1, the problem appears that there is not enough overlap surface between the two components to make a robust and reliable connection.
    More specifically, the side lining 2 comprises a first joint surface 21, which will be overlapped with a second joint surface 11 of the water channel assembly 1. As noted, the overlap in said second joint surface 11 is insufficient.
    As can be seen in Figure 1, due to the concavity defined by the second sunken surface 23, the overlapping area of contact between the first joint surface 21 and the second joint surface 11 is reduced. In order to improve the assembly of the presented body elements, a reinforcement element 3 is designed, located between said joining surface 11, 21, which comprises some particularities described below. Said reinforcing element 3 is represented in figures 2 and 3.
    Said reinforcing element 3 is formed from a main body 30 which, in the embodiment shown, defines a cross-section in a L-shape. In addition, said reinforcing element 3 comprises a fin 31, substantially trapezoidal in shape that protrudes substantially perpendicularly with respect to one of the portions of said L. According to the embodiment shown, said fin 31 covers only a portion of the length of said main body 30, and said fin 31 is fixed to the second sunken surface 23 of the side lining 2, by its lower part. On the other hand, the main body 30 is connected to the water channel assembly 1.
    As can also be seen in the figures, the water channel assembly 1, the side lining 2 and the reinforcement element 3 comprise holes 12, 24 and 32, respectively, for a gas spring (not shown in the figures). This gas spring is used for opening and closing a tailgate of a vehicle.
    These holes 12, 24 and 32 coincide with each other when assembling the water channel assembly 1, the side lining 2 and the reinforcing element 3 to allow the passage of the gas spring. It is emphasized that said reinforcement element 3 is, in particular, the reinforcement of the gas spring, which reinforces the present subset of the bodywork in the face of the efforts transmitted in the opening and closing of a gate of a vehicle.

    According to a second aspect, the present invention also relates to a process for assembling the side lining 2 and the water channel assembly 1 by interposing the reinforcing element 3. This procedure includes the following steps:
    First, the main body 30 of the reinforcing element 3 is fixed to the water channel assembly 1; the lateral lining 2 is then positioned with respect to the water channel 1 through a support on the reinforcing element 3; and the side lining 2 and the water channel assembly 1 are assembled together.
    The fixing of the main body 30 of the reinforcement element 3 to the water channel assembly 1 is preferably done by applying at least one welding point, although the fixing could be carried out in any other suitable way, for example, by means of adhesive or combination of both.
    In addition, at least one welding spot is preferably applied to the flange 31 of the reinforcing element 3 and the lateral lining 2 in the positioning of the lateral lining 2, although it could also be carried out in any other suitable manner. , for example, by adhesive. In particular, at least one weld point is applied that joins the second sunken surface 23 of the side lining 2 with the fin 31 of the reinforcing element 3.
    It should also be noted that the assembly stage of the side lining 2 and the water channel assembly 1 is preferably performed by applying at least one welding point on a first joint surface 21 between the side lining 2 and the water channel assembly 1 , where the first joint surface 21 is located adjacent to the first outer surface 22, and subsequently applying a joint cord on a second joint surface 11 between the side lining 2 and the water channel assembly 1, where the second surface junction 22 is located adjacent to the second sunken surface 23. In this way, welding points are applied in the area where there is sufficient overlapping surface between the side lining 2 and the water channel assembly 1 (area adjacent to the first outer surface 22), and a welding bead in the area where the overlapping surface is insufficient (area adjacent to the second sunken surface 23). Thus both components are correctly assembled and capable of supporting the specific efforts of said area.
    Finally, the coupling of a trimming element in the concavity is carried out

    formed by the second sunken surface 23, so that the at least one weld point applied between the second sunken surface 23 and the fin 31 is hidden from view of a user.
