The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0034] In the related art, since the connection between the shock absorber seat and the wheelhouse longitudinal beam is generally in the Z direction, for the position of the shock absorber seat, if there is a change, it will cause a large adjustment to the structures of the shock absorber seat and the wheelhouse longitudinal beam, greatly increasing the generalization degree of the shock absorber seat and the workload of development. Therefore, how to set a new form of shock absorber to reduce this full development work is the technical problem to be solved by this application.

[0035] The following refers to Figures 1 - 6 Describe a body assembly according to an embodiment of the present utility model.

[0036] The body assembly 1 according to the present utility model includes a shock absorber seat body 11. The shock absorber seat body 11 is formed with a longitudinal connection surface 111 extending in the vehicle height direction on the side surface. The longitudinal connection surface 11 is suitable for connecting to the vehicle body.

[0037] Specifically, a longitudinal connection surface 111 is formed on the side surface of the shock absorber seat body 11. The longitudinal connection surface 111 is suitable for connecting to the vehicle body. Among them, the longitudinal connection surface 111 extends along the height direction of the shock absorber seat body 11. The longitudinal connection surface 111 can be welded to the vehicle body structure. In the prior art, the shock absorber seat body 11 abuts against the vehicle body in the height direction. When the shock absorber seat body 11 is connected to different suspensions, it is necessary to re-develop the parts. In this solution, the shock absorber seat body 11 and the vehicle body are connected through the longitudinal connection surface 111. When the shock absorber seat body 11 is assembled with the vehicle body, if there is a problem of height difference between the shock absorber and the installation points of high and low suspensions, only the installation height of the shock absorber seat body 11 needs to be adjusted, and the welding edge height of the shock absorber seat body 11 needs to be adjusted, without changing the vehicle body structure, so as to improve the generalization of the shock absorber seat body 11, reduce the part development cost, and shorten the development cycle.

[0038] The body assembly 1 according to the present utility model is provided with a longitudinal connection surface 111 extending in the height direction on the shock absorber seat body 11. The shock absorber seat body 11 is overlapped with the vehicle body through the longitudinal connection surface 111. During the overlapping process, the overlapping position of the longitudinal connection surface 111 and the vehicle body is adjustable, so that the shock absorber seat body 11 can be installed to match a variety of suspension structures without adjusting the vehicle body structure, improving the generalization of the shock absorber, reducing the vehicle body development cycle, and reducing the vehicle body development cost.

[0039] According to some embodiments of the present utility model, the vehicle body assembly 1 further includes a wheelhouse longitudinal beam, which is disposed on the side of the shock absorber seat body 11, and at least part of the surface of the wheelhouse longitudinal beam is attached to and fixedly connected to the longitudinal connection surface 111.

[0040] Specifically, the wheelhouse longitudinal beam is disposed on the side of the shock absorber seat body 11, facilitating the fixed connection between the wheelhouse longitudinal beam and the longitudinal connection surface 111 on the shock absorber seat body 11, thereby fixing the wheelhouse longitudinal beam and the shock absorber seat body 11 in the width direction and height direction of the vehicle. When a vehicle collision occurs, since the shock absorber seat body 11 reserves a moving space for the wheelhouse longitudinal beam in the width direction, the longitudinal length of the wheelhouse longitudinal beam invading the cockpit is reduced. At the same time, by adjusting the installation height of the shock absorber seat body 11 and changing the welding point height, the matching installation of various suspensions can be realized, improving the versatility of the shock absorber and facilitating the reduction of development costs.

[0041] According to some embodiments of the present utility model, the shock absorber seat body 11 includes: a top plate 113; an inclined connection wall, which is disposed on at least part of the outer periphery of the top plate 113 and extends obliquely downward along the vehicle height direction relative to the top plate 113; and a side wall, which is connected to the inclined connection wall 113 and forms a longitudinal connection surface 111.

[0042] As Figure 4 shown, the top plate 113 is disposed on the top of the shock absorber seat body 11 for connecting and supporting the shock absorber. An inclined connection wall is disposed on at least part of the outer periphery of the top plate 113, which extends obliquely downward relative to the top plate 113 towards the vehicle bottom. There is a certain angle between the inclined connection wall and the longitudinal connection surface 111, and it is suitable for lap welding with the wheelhouse longitudinal beam. When it is necessary to cope with the height difference of different height suspension installation heights, only the height of the shock absorber seat body 11 needs to be raised, and the welding height of the top plate 113 and the inclined connection plate is increased, without changing the vehicle body structure, improving the versatility of the shock absorber seat; the side wall is connected to the inclined connection wall and forms a longitudinal connection surface 111. By setting the longitudinal connection surface 111 and the inclined connection surface to be welded with the front cover longitudinal beam, the welding area is increased, ensuring the stable welding of the shock absorber seat body 11 and the vehicle body, and facilitating the adjustment of the welding height of the shock absorber seat body 11, improving the versatility.

[0043] Among them, by setting the inclined connection wall and the side wall to be welded with the wheelhouse longitudinal beam, the adjustment amount of the shock absorber in the vehicle Z direction can be adjusted within the range of 10 mm - 30 mm. The preferred value of this application can be 15 mm. When it is necessary to cope with the difference in the height difference of 15 mm between the high and low suspension installation points, only the shock absorber installation surface needs to be raised, and the height of the welding edge between the shock absorber seat body 11 and the wheelhouse longitudinal beam is increased, without changing the vehicle body structure. Thus, the generalization rate of the shock absorber is maximally improved, the development cycle is reduced, and the requirements of platform development are met.

[0044] According to some embodiments of the present utility model, the wheelhouse longitudinal beam includes: a longitudinal beam body 121, and the longitudinal beam body 121 is adapted to be connected to the side wall; a lapping edge, and the lapping edge is arranged on one side of the longitudinal beam body 121 and is adapted to be connected to the inclined connecting wall.

[0045] Specifically, the longitudinal beam body 121 is adapted to be connected to the side wall and is welded to the longitudinal connecting surface 111 to enhance the structural strength of the side part of the vehicle body, provide stable support for the wheels and shock absorbers, and help disperse the forces and vibrations from these components; the lapping edge is arranged on one side of the longitudinal beam body 121 and is welded to the inclined connecting wall. By welding the inclined connecting wall at the top of the shock absorber seat body 11 to the lapping edge, the height of the inclined connecting wall can be adjusted by adjusting the height of the shock absorber seat body 11, so as to adjust the welding height between the shock absorber seat body 11 and the wheelhouse longitudinal beam, without changing the vehicle body structure and reducing the development cost. By welding the longitudinal beam body 121 and the lapping edge to the shock absorber seat body 11, the welding area is increased, and the welding in the vehicle width and height directions is realized, improving the welding strength.

[0046] According to some embodiments of the present utility model, the side wall includes a first side wall 1151 and a second side wall 1152. The first side wall 1151 and the second side wall 1152 are sequentially connected in the vehicle length direction, and the second side wall 1152 extends obliquely away from the wheelhouse longitudinal beam in the vehicle width direction relative to the first side wall 1151.

[0047] As Figure 5 shown, the first side wall 1151 and the second side wall 1152 are formed on the side surface of the shock absorber seat body 11. Longitudinal connecting surfaces 111 adapted to be welded to the wheelhouse longitudinal beam are respectively formed on the first side wall 1151 and the second side wall 1152, and the second side wall 1152 extends obliquely away from the wheelhouse longitudinal beam in the vehicle width direction relative to the first side wall 1151 to form a transverse inclined space between the first side wall 1151 and the second side wall 1152. When the vehicle collides, the second side wall 1152 provides transverse guidance for the movement of the wheelhouse longitudinal beam to increase the transverse displacement amount of the wheelhouse longitudinal beam, thereby reducing the longitudinal displacement amount of the wheelhouse longitudinal beam and reducing the intrusion amount of the wheelhouse longitudinal beam into the cockpit to protect the passengers in the vehicle.

[0048] According to some embodiments of the present utility model, the longitudinal beam body 121 includes: a first connecting section, and the first connecting section extends along the vehicle length direction and is adapted to be connected to the first side wall 1151; a second connecting section, and the second connecting section is connected to the first connecting section and is inclined towards the shock absorber seat body 11 in the width direction, and the second connecting section is adapted to be connected to the second side wall 1152.

[0049] Specifically, the first connecting section is correspondingly arranged with the first side wall 1151 and is adapted to be welded to the first side wall. The second connecting section is correspondingly welded to the second side wall 1152. The second connecting section is inclined in the direction away from the first connecting section and towards the shock absorber seat body 11 to ensure stable welding of the second connecting section and the second side wall 1152. When a vehicle collides, due to the certain angle between the first side wall 1151 and the longitudinal connecting surface 111, the second side wall 1152 can provide lateral guidance for the wheelhouse longitudinal beam, and the wheelhouse longitudinal beam can generate lateral displacement along the second side wall 1152, thereby reducing the longitudinal intrusion amount of the wheelhouse longitudinal beam and ensuring passenger safety.

[0050] In some embodiments, a third side wall 1153 is provided on the side of the first side wall 1151 facing away from the second side wall 1152. The third side wall 1153 is inclined in the direction away from the second side wall 1152 and towards the direction away from the first side wall 1151, so that a lateral angle is formed between the third side wall 1153 and the longitudinal connecting surface, providing lateral guidance for the wheelhouse longitudinal beam and facilitating the reduction of the longitudinal intrusion amount of the wheelhouse longitudinal beam.

[0051] According to some embodiments of the present invention, the angle between the first side wall 1151 and the second side wall 1152 is α1, and it satisfies: 15° < α1 < 30°.

[0052] Specifically, when a vehicle collides, the second side wall 1152 can provide a moving space for the wheelhouse longitudinal beam and reduce the intrusion amount of the wheelhouse longitudinal beam into the occupant compartment. The second side wall 1152 is arranged on the front side of the wheelhouse longitudinal beam. The angle between the second side wall 1152 and the first side wall 1151 is α1, and it satisfies 15° < α1 < 30°. Among them, when α1 > 15°, it can ensure that the second side wall 1152 can provide sufficient lateral component force for the wheelhouse longitudinal beam to guide the wheelhouse longitudinal beam to generate lateral displacement, which is beneficial to reducing the longitudinal length of the wheelhouse longitudinal beam invading the occupant compartment and ensuring passenger safety. When α1 < 30°, it can ensure that there is sufficient space between the second side wall 1152 and the first side wall 1151 for the movement of the wheelhouse longitudinal beam and reduce the intrusion amount of the wheelhouse longitudinal beam.

[0053] According to some embodiments of the present invention, the inclined connecting wall includes: a first extending wall 1141, the first extending wall 1141 is connected to the first side wall 1151 and extends obliquely from the top plate 113 towards the bottom; a second extending wall 1142, the second extending wall 1142 is connected to the second side wall 1152 and extends obliquely from the top plate 113 towards the bottom.

[0054] As Figure 5As shown, the first extension wall 1141 and the second extension wall 1142 are respectively inclined downward relative to the top plate to form two inclined welding surfaces on one side of the top plate 113 facing the wheelhouse longitudinal beam. The first extension wall 1141 is connected to the first side wall 1151 and is adapted to be welded to the wheelhouse longitudinal beam. The second extension wall 1142 is connected to the second side wall 1152 and is adapted to be welded to the wheelhouse longitudinal beam. By arranging the first extension wall 1141 and the second extension wall 1142 on one side of the top plate 113 facing the wheelhouse longitudinal beam to lap with the wheelhouse longitudinal beam, the shock absorber seat body 11 can adapt to the height difference between the high and low suspensions. By adjusting the height of the mounting surface of the shock absorber seat body 11, the heights of the first extension wall 1141 and the second extension wall 1142 are adjusted, so as to achieve the installation between the high and low suspensions without modifying the body structure, thereby reducing the body development cycle and cost.

[0055] According to some embodiments of the present invention, an avoidance notch 1223 is formed on the lapping edge to divide the lapping edge into a first lapping edge 1221 and a second lapping edge 1222. The first lapping edge 1221 is connected to the first extension wall 1141, and the second lapping edge 1222 is connected to the second extension wall 1142.

[0056] As Figure 3 shown, an avoidance notch 1223 is formed on the lapping edge. The first lapping edge 1221 and the second lapping edge 1222 are respectively formed on both sides of the avoidance notch 1223. The first lapping edge 1221 is welded to the first extension wall 1141, and the second lapping edge 1222 is welded to the second extension wall 1142. By adjusting the installation height of the shock absorber seat body 11, the heights of the first extension wall 1141 and the second extension wall 1142 are changed, so as to ensure the welding of the shock absorber seat body 11 with bodies of different heights, improving the versatility. By forming the avoidance notch 1223 on the lapping edge, it is beneficial to reduce the number of welding layers between the shock absorber seat body 11 and the wheelhouse longitudinal beam, and improve the welding strength between the wheelhouse longitudinal beam and the shock absorber seat body 11.

[0057] According to some embodiments of the present invention, a guiding surface 1131 is formed on the top plate 113. The guiding surface 1131 is connected to the inclined connecting wall and gradually decreases in height in the direction away from the center of the shock absorber seat body 11.

[0058] As Figure 4 shown, the guiding surface 1131 is formed on the top plate 113 of the shock absorber seat body 11 and is connected to the second extension wall 1142. The guiding surface 1131 gradually decreases in height in the direction away from the center of the shock absorber seat body 11, so that the guiding surface 1131 generates an inclined plane inclined relative to the height direction on the top of the shock absorber seat body 11, providing an avoidance space in the height direction for the connection between the shock absorber seat body 11 and the wheelhouse longitudinal beam, increasing the vehicle Z-direction space, and reducing the impact on the occupant's head.

[0059] According to some embodiments of the present utility model, the vehicle body assembly 1 further includes: reinforcing ribs 112, and the reinforcing ribs 112 are configured to be multiple and are arranged at intervals on the surface of the shock absorber seat body 11.

[0060] As Figure 5 shown, a plurality of reinforcing ribs 112 are arranged at intervals on the shock absorber seat body 11. By arranging the plurality of reinforcing ribs 112 at intervals, the stress distribution is optimized, local stress concentration is reduced, the overall strength of the shock absorber seat body 11 is ensured, so as to withstand more vibrations and impact forces, and the safety is improved.

[0061] In some embodiments, the shock absorber seat assembly 1 further includes a front longitudinal beam sealing plate 14, a support plate 15 and a reinforcing plate 16. The front longitudinal beam sealing plate 14 is arranged on one side in the width direction of the shock absorber seat body 11 and extends in the length direction; the support plate 15 is arranged at the end of the front longitudinal beam sealing plate 14 and the support plate 15 is connected to the wheelhouse longitudinal beam, and the reinforcing plate 16 is arranged on one side of the shock absorber seat body 11 in the length direction and connects the wheelhouse longitudinal beam and the front longitudinal beam sealing plate 14; wherein, a weight reduction hole is formed around between the support plate 15, the front longitudinal beam sealing plate 14, the wheelhouse longitudinal beam and the reinforcing plate 16, and an annular structure is constructed.

[0062] Specifically, an annular weight reduction hole is constructed between the support plate 15, the front longitudinal beam sealing plate 14, the wheelhouse longitudinal beam and the reinforcing plate 16 as Figure 2 shown. By combining the support plate 15, the front longitudinal beam sealing plate 14, the reinforcing plate 16 and the wheelhouse longitudinal beam into an annular structure, the number of parts of the intermediate connection structure of the vehicle front wheelhouse assembly is reduced, which is beneficial to reducing the weight of the vehicle front wheelhouse assembly, realizing vehicle body lightweight. At the same time, this annular structure can increase the collision resistance of the front wheelhouse assembly. By arranging the front longitudinal beam sealing plate 14 and the support plate 15, the structural strength of the front wheelhouse assembly is enhanced, and stable support is provided for the wheelhouse longitudinal beam.

[0063] The reinforcing plate 16 connects the wheelhouse longitudinal beam and the front longitudinal beam sealing plate 14 and is welded to the front wheelhouse 10. Multiple CO2 shielded weldings can be arranged between the reinforcing plate 16 and the front longitudinal beam sealing plate 14 to improve the connection strength. When the vehicle collides and the front wheelhouse 10 moves, the reinforcing plate 16 can pull the front wheelhouse 10 and limit the movement of the front wheelhouse 10, avoiding the failure and separation of the welding joint between the front wheelhouse 10 and the wheelhouse longitudinal beam, and improving the safety.

[0064] In some embodiments, a first connection area and a second connection area are arranged on the wheelhouse longitudinal beam. The first connection area is connected to the support plate 15, and the second connection area is arranged in a fitting manner with the longitudinal connection surface 111; wherein, a crush energy absorption part 134 is formed on the wheelhouse longitudinal beam, and the crush energy absorption part 134 is located between the first connection area and the second connection area.

[0065] Specifically, the first connection area and the support plate 15 can be connected by welding to ensure stable connection between the support plate 15 and the wheelhouse longitudinal beam. The second connection area is arranged in contact with the longitudinal connection surface 111 and can be connected by welding to ensure stable connection between the shock absorber seat body 11 and the wheelhouse longitudinal beam. A crush energy absorption part 134 is arranged between the first connection area and the second connection area. The crush energy absorption part 134 extends longitudinally along the wheelhouse longitudinal beam. When a vehicle collides, the crush energy absorption part 134 is bent to absorb energy, so as to avoid the failure of the welding points at the connection between the wheelhouse longitudinal beam and the vehicle body. Among them, if the middle part of the wheelhouse longitudinal beam is bent in the height direction, the support plate 15 applies a downward peeling force to the wheelhouse longitudinal beam. The welding points have weak ability to bear the peeling force and are prone to failure. By arranging the crush energy absorption part 134 between the first connection area and the second connection area, when the vehicle collides, the crush energy absorption part 134 intervenes in time and generates folding energy absorption in the height direction before the welding points fail, so as to change the component force at the welding points and avoid the generation of a large peeling force at the welding points and failure, thereby improving the safety of the vehicle.

[0066] In some embodiments, the wheelhouse longitudinal beam includes a longitudinal beam outer plate 131, a longitudinal beam inner plate 132 and a longitudinal beam rear section 133. The longitudinal beam outer plate 131 is attached to and welded to the longitudinal connection surface 111; the longitudinal beam inner plate 132 is arranged inside the longitudinal beam outer plate 131, and at least part of the longitudinal beam inner plate 132 overlaps with the longitudinal beam outer plate 131; the longitudinal beam rear section 133 is arranged at the rear side of the longitudinal beam inner plate 132, and the longitudinal beam rear section 133 is connected to the support plate 15.

[0067] Specifically, the wheelhouse longitudinal beam is composed of a longitudinal beam outer plate 131, a longitudinal beam inner plate 132 and a longitudinal beam rear section 133. The longitudinal beam outer plate 131, the longitudinal beam inner plate 132 and the reinforcement plate 16 together form the SHOTGUN structure of the vehicle to bear and transmit the collision impact force. Among them, the longitudinal beam outer plate 131 is attached to and welded to the longitudinal connection surface 111 of the shock absorber seat body 11. By adjusting the height of the welding points between the longitudinal connection surface 111 and the longitudinal beam outer plate 131, the shock absorber seat body 11 can be matched and installed with a variety of suspensions, and there is no need to change the structure of the wheelhouse longitudinal beam, realizing the universality of the shock absorber and reducing the part R & D cost; the longitudinal beam inner plate 132 is arranged inside the longitudinal beam outer plate 131, and at least part of the longitudinal beam inner plate 132 overlaps with the longitudinal beam outer plate 131 to increase the strength and stiffness of the wheelhouse longitudinal beam, so that it is not easy to deform when bearing loads. The longitudinal beam rear section 133 is arranged at the rear side of the longitudinal beam inner plate 132, and the longitudinal beam rear section 133 is connected to the support plate 15 to realize the connection between the wheelhouse longitudinal beam and the front wheelhouse assembly. By dividing the wheelhouse longitudinal beam into the longitudinal beam outer plate 131, the longitudinal beam inner plate 132 and the longitudinal beam rear section 133, and connecting the three components to each other, the overall strength of the wheelhouse longitudinal beam is improved to bear greater loads and impact forces, thereby improving safety.
