[0076] The utility model can provide X - direction and Y - direction supports for the A - pillar cavity 400, form a better force - transmission structure, and is more helpful for keeping the A - pillar cavity intact and reducing the deformation amount during a collision; when higher stiffness and strength are required for safety performance, it is not necessary to increase the thickness of the side wall reinforcement plate and the inner side wall panel as a whole, which can reduce costs and the weight of the whole vehicle; the utility model can reduce the number of parts. Only one part (the front door upper hinge reinforcement plate) provides screw connection points for the front door upper hinge, and also enhances the collision energy absorption of the upper A - pillar, realizing fewer parts.

[0086] After the box structure is formed and trimmed, a connecting plate process is carried out to solve the problem of the forming of the nut projection welding surface; it is designed as a self-welding structure to solve the problem of difficult forming of "box-shaped" parts; the self-welding structure also improves the strength of the part itself and can better withstand the force from the X direction during a collision.
[0087] The difference between this embodiment and the second embodiment lies in:
[0088] Both the rear connecting plate 105 and the front connecting plate 106 are in a "U" - shaped structure. The upper and lower sides of the "U" - shaped structure are respectively connected to the upper connecting plate 103 and the lower connecting plate 104 to form a box - body structure.

[0097] The utility model can provide X-direction and Y-direction support for the A-pillar cavity 400, form a better force transmission structure, and is more helpful for maintaining the integrity of the A-pillar cavity and reducing the deformation amount during a collision; when higher stiffness and strength are required for safety performance, it is not necessary to increase the thickness of the side wall reinforcement plate and the inner side wall panel as a whole, which can reduce costs and the weight of the whole vehicle; the utility model can reduce the number of parts. Only one part (the front door upper hinge reinforcement plate) provides a screw connection point for the front door upper hinge, and also enhances the collision energy absorption of the upper A-pillar, realizing fewer parts.
[0098] Hinge mounting holes for connecting the upper hinge are provided on the hinge mounting surface 101. The number of hinge mounting holes is two, which can strengthen the firm connection between the upper hinge and the front door upper hinge reinforcement plate 100.
[0099] The box structure is an axisymmetric structure with uniform stress, which can better absorb collision energy.
[0100] The box structure includes a connecting plate extending from the hinge mounting surface 101 towards the inner side wall panel 300. The connecting plate includes an upper connecting plate 103, a lower connecting plate 104, a front connecting plate 106, and a rear connecting plate 105 respectively connected to the upper, lower, front, and rear of the hinge mounting surface 101. The hinge mounting surface 101 is connected to the upper connecting plate 103, the lower connecting plate 104, the front connecting plate 106, and the rear connecting plate 105 to form a hinge reinforcement cavity 109, and one side of the hinge reinforcement cavity 109 facing the inner side wall panel 300 is open.
[0101] It should be noted that the "front and rear" in the present utility model are defined according to the front and rear directions of the vehicle.
[0102] The front connecting plate 106 is connected to the front wall of the side wall reinforcement plate 200, preferably by welding; the rear connecting plate 105 is connected to the rear wall of the side wall reinforcement plate 200 by welding; the length direction of the box structure is parallel to the X direction of the vehicle. The front door upper hinge reinforcement plate fills the entire A-pillar cavity 400 in the X direction. During a collision, it can more effectively support the A-pillar cavity 400, enhance the strength of the A-pillar, and absorb more collision energy.
[0103] Specifically, the upper connecting plate 103 and the lower connecting plate 104 are connected to the inner side panel 300 by bolts arranged along the vehicle Y direction. The inner side panel is connected to the front door upper hinge reinforcing plate in the Y direction, which better connects the side panel reinforcing plate and the inner side panel, forming a complete box-shaped load-bearing structure during a collision and improving the collision performance.
[0104] The box structure further includes flanges extending upward from the upper connecting plate 103 and downward from the lower connecting plate 104. The flanges are connected to the inner side panel 300, and the flanges can increase the connection area with the inner side panel 300 and enhance the connection stability.
[0105] A plurality of bolt mounting holes are formed in the flanges, and nuts are projection welded on one side of the bolt mounting holes facing the side panel reinforcing plate.
[0106] Specifically, 2-4 nuts are projection welded on the flanges. After the side panel assembly and the lower body assembly are assembled, the above-mentioned flanges are attached to the inner side panel 300, and bolts are driven in from the inside of the vehicle to complete the connection between the inner side panel 300 and the front door upper hinge reinforcing plate 100.
[0107] After the box structure is formed and trimmed, the connecting plate process is carried out, which solves the problem of the forming of the nut projection welding surface; it is designed as a self-welding structure, which solves the problem of difficult forming of "box-shaped" parts; the self-welding structure also improves the strength of the part itself and can better withstand the force from the X direction during a collision.
[0108] The difference between this embodiment and the second embodiment is as follows:
[0109] Counterbore holes 107 are provided on the upper connecting plate 103 and the lower connecting plate 104, which not only reduces the product weight but also minimizes the performance weakening caused by the opening.
[0110] Electrophoresis holes 108 are provided on the upper connecting plate 103 and the lower connecting plate 104 to ensure the fluidity of the electrophoresis liquid during electrophoresis.
[0111] Specifically, the shape of the electrophoresis hole 108 is circular.
[0112] As Figure 3 shown, a first receiving groove 201 matching the front door upper hinge reinforcing plate 100 is formed on the side panel reinforcing plate 200 to strengthen the connection firmness between the box structure and the side panel reinforcing plate 200.
[0113] A second receiving groove 301 for receiving the upper connecting plate 103 and the lower connecting plate 104 is provided on the inner side panel 300 to strengthen the connection firmness between the reinforcing box structure and the inner side panel 300.
[0114] The rear connecting plate 105 is provided with a second mating surface 110, the second mating surface 110 is connected to the rear side of the hinge mounting surface 101, and the shape of the second mating surface 110 is adapted to the shape of the side wall reinforcing plate 200, facilitating the positioning of the box body structure.
