[0033] Referring to Figures 1 to 5 , a schematic structural diagram of a bracket structure according to an embodiment of the present application is shown. The bracket structure may specifically include: a bracket body 10 and a plurality of buffer energy absorption parts 20; the buffer energy absorption parts 20 are connected to the bracket body 10, and the buffer energy absorption parts 20 protrude along a first direction X. The plurality of buffer energy absorption parts 20 are arranged at intervals along a second direction Y, wherein the first direction X is the length direction of the vehicle, and the second direction Y is the width direction of the vehicle.

[0034] In the embodiment of the present application, when the vehicle is subjected to a low-speed collision, the bracket structure is subjected to an impact force along the length direction of the vehicle. In the present application, buffer energy absorption parts 20 protruding along the first direction X, that is, the length direction of the vehicle, are provided on the bracket body 10. The buffer energy absorption parts 20 can deform, reduce the stiffness of the bracket structure in the thickness direction, absorb the impact force received by the bracket structure along the length direction of the vehicle, buffer the impact force received by the outer panel of the rear enclosure, and reduce the impact damage received by the outer panel of the rear enclosure. Thereby, the buffer energy absorption effect of the bracket structure is enhanced, the damage risk of the outer panel of the rear enclosure is reduced, and the maintenance cost is reduced.

[0035] Specifically, in the embodiment of the present application, the bracket structure may be a rear bumper middle bracket, which is located between the outer panel of the vehicle rear enclosure and the rear bumper assembly 50, and is used to provide a clamping structure 60 and a supporting function for the rear bumper assembly 50, so that the rear bumper assembly 50 is firmly clamped, and assist in controlling the gap surface difference between the rear bumper assembly 50 and the vehicle tailgate. Moreover, the rear bumper middle bracket is within the low-speed collision assessment area, and the rear bumper middle bracket also plays a role in buffering deformation and absorbing energy to reduce the damage degree of the outer panel of the rear enclosure, so that the outer panel of the rear enclosure can be repaired under low-speed collision conditions and is exempt from replacement.

[0036] Traditionally, the stiffness of the rear bumper middle bracket in the first direction X, i.e., the length direction of the vehicle, is generally close to the stiffness in the height direction of the vehicle. When the rear bumper middle bracket is within the low-speed collision assessment area, in order to meet the requirements of the gap surface difference between the rear bumper assembly 50 and the tailgate, the overall stiffness of the rear bumper middle bracket is relatively strong, resulting in insufficient deformation buffering and energy absorption of the rear bumper middle bracket under low-speed collision conditions, and a large degree of damage to the outer panel of the rear enclosure, making it unable to be repaired. However, in the embodiment of the present application, a buffer energy absorption portion 20 protruding along the first direction X is provided on the bracket body 10, so that the buffer energy absorption portion 20 can reduce the stiffness of the bracket structure in the vehicle length direction through deformation, absorb the collision received by the vehicle rear bumper assembly 50, thereby reducing the damage degree of the outer panel of the rear enclosure, being exempt from replacement, and reducing the maintenance cost.

[0037] Exemplarily, in the embodiment of the present application, the number of the buffer energy absorption portions 20 may be 5, 6, 8, 10, etc., and can be set according to the size of the bracket body 10, the buffer requirements, etc., according to the actual situation. The specific number of the buffer energy absorption portions 20 in the embodiment of the present application may not be limited.

[0038] Optionally, in the embodiment of the present application, the bracket body 10 includes a first side 11 and a second side 12 arranged in opposite directions. The first side 11 is used to connect the outer panel of the rear enclosure, and the second side 12 is used to connect the rear bumper assembly 50. The buffer energy absorption portion 20 is connected to the second side 12. Specifically, when the rear of the vehicle is collided, the collision force first acts on the rear bumper assembly 50, and then is transmitted to the rear side enclosure outer panel through the bracket structure. The second side 12 of the bracket structure is used to connect the rear bumper assembly 50 and is the side that is first affected by the collision force. Therefore, compared with the buffer energy absorption portion 20 being arranged on the first side 11, connecting the buffer energy absorption portion 20 to the second side 12 enables the buffer energy absorption portion 20 to buffer and absorb the collision force received by the bumper assembly first, having a better buffer energy absorption effect.

[0039] In an embodiment of the present application, optionally, a plurality of mating points 30 are provided on the bracket body 10, and the plurality of mating points 30 are spaced apart along the second direction Y; at least one buffer and energy absorption part 20 is provided between two adjacent mating points 30. Specifically, the mating point 30 is used to realize the screw connection and mating between the bracket structure and the outer panel of the rear enclosure. By providing the buffer and energy absorption part 20 between two adjacent mating points 30, interference between the buffer and energy absorption part 20 and the mating point 30 can be avoided, and the connection between the bracket structure and the outer panel of the rear enclosure can be prevented from being affected.

[0040] For example, in an embodiment of the present application, one buffer and energy absorption part 20 can be provided between two adjacent mating points 30, or two buffer and energy absorption parts 20 can be provided, or three buffer and energy absorption parts 20, etc. It can be set according to the actual needs according to the distance between two adjacent mating points 30 and the buffer and energy absorption requirements. The specific number of the buffer and energy absorption parts 20 provided between two adjacent mating points 30 in the embodiment of the present application may not be limited.

[0041] Optionally, in an embodiment of the present application, the buffer and energy absorption part 20 is a shelled box body 21 with a hollow structure. In this way, since the shelled box body 21 has a hollow structure, the buffer and energy absorption part 20 can undergo a large deformation and has a good energy absorption and buffering effect.

[0042] In an embodiment of the present application, optionally, the shelled box body 21 is provided with a plurality of first weight reduction holes 22, and the plurality of first weight reduction holes 22 are distributed on both sides of the shelled box body 21. For example, Figure 1 As shown, the plurality of first weight reduction holes 22 can be distributed on both sides of the shelled box body 21 along the height direction of the vehicle. By the first weight reduction holes 22, the weight of the shelled box body 21 is reduced, which is beneficial to the lightweight design of the bracket structure. During the preparation process, the first weight reduction holes 22 can be obtained by reducing the glue on the shelled box body 21, or larger-sized openings can be opened on the shelled box body 21, and then the parts to be connected are connected by supplementing the material thickness, so that the shelled box body 21 has a relatively complete structure after the glue is reduced.

[0043] For example, in an embodiment of the present application, the plurality of first weight reduction holes 22 can be symmetrically distributed on both sides of the shelled box body 21. In addition, the plurality of first weight reduction holes 22 can also be staggeredly distributed on both sides of the shelled box body 21, and the embodiment of the present application may not limit this. For example, the number of the first weight reduction holes 22 can be 4, 6, 7, 8, etc., and can be set according to actual needs. The specific number of the first weight reduction holes 22 provided in the embodiment of the present application may also not be limited.

[0044] Optionally, in the embodiment of the present application, the bracket structure further includes a support rib 40, which is connected to the outer top surface of the shelled box body 21 and is used to support the rear bumper assembly 50. Specifically, the top surface of the shelled box body 21 is the side close to the vehicle roof. When connecting the bracket structure to the rear bumper assembly 50, the top surface of the bracket structure is usually supported on the rear bumper assembly 50. Therefore, a support rib 40 is provided outside the top surface of the shelled box body 21 to be clamped and supported on the flanging structure of the rear bumper assembly 50, improving the connection reliability and stability of the bracket structure to the rear bumper assembly 50.

[0045] Optionally, in the embodiment of the present application, the number of the support ribs 40 is multiple, and the multiple support ribs 40 are spaced apart along the second direction Y outside the top surface of the shelled box body 21; the shelled box body 21 is further provided with a plurality of second weight reduction holes 23, and the plurality of second weight reduction holes 23 are distributed between two adjacent support ribs 40. By way of example, as Figure 2 shown, each shelled box body 21 can be provided with a plurality of support ribs 40 to improve the support reliability of the bracket structure to the rear bumper assembly 50. Since the support ribs 40 have a good support effect, second weight reduction holes 23 are provided between two adjacent support ribs 40, which can further reduce the weight of the shelled box body 21 on the basis of ensuring good support strength of the support structure, facilitating the lightweight design of the bracket structure.

[0046] By way of example, in the embodiment of the present application, the second side 12 of the bracket body 10 is further provided with a clamping structure 60, such as a buckle or other structures, for clamping the rear bumper assembly 50. The number of the clamping structures 60 can be multiple, and the multiple clamping structures 60 are spaced apart along the second direction Y. By way of example, the number of the clamping structures 60 can be 5, 6, 8, 9, etc., which can be set according to actual needs, and the specific number of the clamping structures 60 in the embodiment of the present application may not be limited.

[0047] Optionally, the bracket body 10 and the buffer energy absorption part 20 are integrally formed structures. In this way, the connection strength between the bracket body 10 and the buffer energy absorption part 20 is relatively high, and material loss and manufacturing processes are reduced.

In this way, in the case of a low-speed collision of the vehicle, the bracket structure is subjected to an impact force along the length direction of the vehicle. In the present application, buffer and energy absorption parts protruding along the first direction, that is, the length direction of the vehicle, are arranged on the bracket body. The buffer and energy absorption parts can deform, reduce the stiffness of the bracket structure in the thickness direction, absorb the impact force received by the bracket structure along the length direction of the vehicle, buffer the impact force received by the rear outer panel, and reduce the impact damage received by the rear outer panel. Thereby, the buffer and energy absorption effect of the bracket structure is enhanced, the damage risk of the rear outer panel is reduced, and the maintenance cost is reduced.
