[0026] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0027] Reference below Figure 1-Figure 3 The bumper side bracket assembly 100 according to the embodiment of the utility model is described, which can integrate the energy absorption box bracket 2 with the bumper side bracket 1 into one body, thereby avoiding the problem of bending the bumper side bracket 1 when connecting it to the frame. This can also reduce the plate material to a certain extent and improve the molding efficiency of the product process.

[0028] Combination Figure 1-Figure 3 As shown, the bumper side bracket assembly 100 according to the first aspect of the utility model mainly includes a bumper side bracket 1 and an energy absorption box bracket 2. The bumper side bracket 1 is used to connect with the bumper 200 of the vehicle, and the energy absorption box bracket 2 is used to connect with the energy absorption box 300 and the longitudinal beam 400 of the vehicle respectively. The energy absorption box bracket 2 is connected to the bumper side bracket 1, wherein one end edge of the bumper side bracket 1 is overlapped with the edge of the energy absorption box bracket 2 to form a shape.

[0029] Specifically, the bumper side bracket 1 and the energy absorption box bracket 2 both extend in the lateral direction of the vehicle (that is, the left-right direction), and the two are connected to each other. For example, the energy absorption box bracket 2 is connected between the energy absorption box 300 and the longitudinal beam 400 of the vehicle along the longitudinal direction (that is, the front-to-back direction); in the transverse direction, one end of the bumper side bracket 1 is connected to one end of the energy absorption box bracket 2, and the other end of the bumper side bracket 1 can form a connection relationship with the bumper 200, so that the integrated effect of the bumper side bracket 1 and the energy absorption box bracket 2 can be achieved. Moreover, compared with the traditional independent bumper side bracket (which needs to be designed as a bending structure for installation with the frame, but it is easy to produce process defects at the bending position, affecting its bearing capacity), the embodiment in this case can avoid the problem of bending the bumper side bracket 1 when it is connected to the frame (such as the longitudinal beam 400 on the frame). This can reduce the material used in the plate to a certain extent, improve the molding efficiency of the product process, and avoid a series of process and cracking problems caused by bending, thereby improving the practicality and reliability of the bumper side bracket assembly 100.

[0030] Furthermore, a conventional bumper side bracket needs to be welded with a reinforcing plate at the bending area where it is connected to the longitudinal beam 400 for local reinforcement. However, since the reinforcing plate is close to the corner edge of the bumper side bracket, welding process problems may occur during the welding process, which may cause the edge of the sheet metal to be burned, thereby affecting the bearing performance of the overall structure and causing cracking. The bumper side bracket assembly 100 in this embodiment does not need to be designed to be bent, thereby avoiding this process defect and avoiding the burning edge problem caused by bending and welding.

[0031] In addition, the edge of one end of the bumper side bracket 1 and the edge of the energy absorption box bracket 2 are overlapped, and the overlap connection has the advantages of simple construction and firm connection, thereby improving the structural reliability of the bumper side bracket assembly 100.

[0032] Therefore, by integrating the energy absorption box bracket 2 with the bumper side bracket 1, the problem of bending the bumper side bracket 1 when connecting it to the frame can be avoided. This can also reduce the use of sheet materials to a certain extent, improve the molding efficiency of the product process, and thus improve the practicality and reliability of the bumper side bracket assembly 100.

[0033] According to some optional embodiments of the present invention, combined with Figure 1-Figure 3 As shown, a first flange 11 is provided at the edge of the bumper side bracket 1. In detail, the outer edge of the bumper side bracket 1 is bent with the first flange 11, which can increase the spatial mode of the bumper side bracket 1, thereby improving its bending and torsional rigidity; and can also prevent the vibration frequency of the bumper 200 from resonating with the ground excitation, thereby improving the vibration reduction performance of the bumper side bracket 1.

[0034] According to some optional embodiments of the present invention, combined with Figure 1-Figure 3 As shown, one end of the bumper side bracket 1 is connected to the energy absorption box bracket 2, and the upper side of the other end of the bumper side bracket 1 is connected to a supplementary bracket 500, and the supplementary bracket 500 is used to connect to the upper end of the bumper 200. Specifically, in the lateral direction, the upper side of the end of the bumper side bracket 1 away from the energy absorption box bracket 2 is connected to the supplementary bracket 500, and the supplementary bracket 500 is then connected to the upper end of the bumper 200, so that the bumper side bracket 1 can match the internal contour of the bumper 200 and extend its own structure, and then indirectly connected to the bumper 200 as a whole through the supplementary bracket 500, thereby increasing the connection reliability and fit between the bumper 200 and the bumper side bracket 1.

[0035] According to some optional embodiments of the present invention, combined with Figure 1-Figure 3As shown, the bumper side bracket assembly 100 also includes a reinforcing plate 3, one end of the bumper side bracket 1 is connected to the energy absorption box bracket 2, and the other end of the bumper side bracket 1 is used to connect to the bumper 200, and the reinforcing plate 3 is arranged on a side surface of the bumper side bracket 1, and the reinforcing plate 3 is arranged at one end of the bumper side bracket 1 adjacent to the other end of the bumper side bracket 1.

[0036] Among them, since the shear damage of the bumper side bracket 1 adjacent to the energy absorption box bracket 2 is the largest when subjected to external force, the reinforcement plate 3 installed on the bumper side bracket 1 is located at the end closer to the energy absorption box bracket 2 in the lateral direction. This can increase the structural strength of the weakly stressed area on the bumper side bracket 1, thereby improving the structural reliability of the bumper side bracket 1.

[0037] In addition, a reinforcing plate 3 is screwed onto one side surface of the bumper side bracket 1. This can, on the one hand, enhance the structural strength of each other, thereby improving the structural reliability of the bumper side bracket 1; on the other hand, it can increase the overall vibration frequency, thereby avoiding resonance between the vibration frequency of the bumper 200 and the ground excitation, thereby improving the vibration damping performance of the bumper side bracket 1.

[0038] Specifically, combined Figure 1-Figure 3 As shown, the reinforcing plate 3 and the bumper side bracket 1 are connected by fasteners. It is understandable that the fasteners connect the reinforcing plate 3 and the bumper side bracket 1 as a whole, which is easier to disassemble and replace compared to other connection methods, such as bonding, welding, etc., thereby improving installation flexibility.

[0039] Furthermore, combined with Figure 1-Figure 3 As shown, the bumper side bracket 1 is provided with a weight-reducing hole 12 penetrating along the thickness direction thereof. The weight-reducing hole 12 is formed in the middle of the bumper side bracket 1, so that the weight of the bumper side bracket 1 can be reduced on the basis of satisfying the structural strength of the bumper side bracket 1, and the vibration transmission can be reduced, thereby facilitating the lightweight effect and vibration reduction performance of the bumper side bracket 1.

[0040] Specifically, combined Figure 1-Figure 3 As shown, the edge of the weight-reducing hole 12 is provided with a second flange 121. The circumferential edge of the weight-reducing hole 12 is bent with the second flange 121, which can increase the spatial mode of the bumper side bracket 1, thereby improving its bending and torsional rigidity; it can also avoid the vibration frequency of the bumper 200 from resonating with the ground excitation, thereby improving the vibration reduction performance of the bumper side bracket 1.

[0041] According to some optional embodiments of the present invention, combined with Figure 1-Figure 3As shown, the bumper side bracket 1 is provided with a plurality of bumper mounting holes 13, and at least one bumper mounting hole 13 is set as an elliptical hole or an oblong hole. It is understandable that the bumper side bracket 1 is provided with a plurality of bumper mounting holes 13 for connecting with the bumper 200, and the opening directions of the bumper mounting holes 13 are different. For example, the bumper mounting holes 13 are formed along the longitudinal direction and the vertical direction (that is, the up and down direction of the vehicle) as shown in the figure, so that it is convenient for the fastener to establish a force connection relationship with the bumper 200 from different directions, thereby improving the connection tightness and reliability between the bumper 200 and the bumper side bracket 1.

[0042] In addition, at least one bumper mounting hole 13 can be set to an elliptical hole or an oblong hole, so as to avoid the problem of the bumper mounting hole 13 being difficult to install due to the installation tolerance between the integrated bumper side bracket assembly 100 and the bumper 200.

[0043] According to some optional embodiments of the present invention, combined with Figure 1-Figure 3 As shown, the edge of one end of the bumper side bracket 1 is welded to the edge of the energy absorption box bracket 2 that overlaps; and / or the energy absorption box bracket 2 is provided with a plurality of longitudinal beam mounting holes 21. Among them, the edge of one end of the bumper side bracket 1 in the transverse direction and the edge of one end of the energy absorption box bracket 2 in the transverse direction are overlapped and connected together by welding. Compared with other connection methods such as butt welding or screw connection, overlap welding has the advantages of simple structure, easy operation, fast welding speed, high welding quality and high weld strength. Therefore, the connection process in this embodiment can improve the overall connection reliability and convenience of the bumper side bracket assembly 100. In addition, the energy absorption box bracket 2 is provided with a plurality of longitudinal beam mounting holes 21 for connecting with the longitudinal beam 400, so that the connection strength between the energy absorption box bracket 2 and the longitudinal beam 400 can be improved.

[0044] The vehicle according to the embodiment of the second aspect of the utility model includes the bumper side bracket assembly 100 of the above embodiment. The vehicle having the bumper side bracket assembly 100 can improve the load-bearing capacity of the vehicle bumper 200 and can also improve the molding efficiency of the bumper side bracket 1 parts on the vehicle, thereby improving the vehicle reliability and reducing the vehicle manufacturing cost.
