Description
Technical Field
[0001] The utility model relates to the technical field of automobile body structures, and particularly relates to a front bumper mounting assembly and a vehicle. Background Art
[0002] An automobile bumper is a device that absorbs and reduces external impact forces and plays a safety protection role for the front and rear parts of the vehicle body. With the development of new energy vehicles, more and more vehicle models have cancelled the traditional upper grille of the front bumper and covered this part to serve as the outer surface of the shape. However, from the perspective of ensuring the overall outer surface quality and the aesthetic appearance of the overall outer surface, it is not suitable to set various strengthening structures on the outer surface. This has led to relatively thin structures in some parts of the front bumper body, insufficient structural strength in the flanging part, and at the same time, the front bumper body is prone to dropping, and even the flanging part is cracked and damaged.
[0003] Although in the prior art, there is a structure of the front bumper mounting assembly that increases the structural strength of the flanging part of the front bumper body by setting a support skeleton on the flanging of the front bumper body to prevent the flanging part from breaking, but such a structure cannot solve the problems of the front bumper flipping and dropping; and another structure of the front bumper mounting assembly strengthens the connection strength between the front bumper assembly and the vehicle body structure by setting a strengthening skeleton above the lower grille of the front bumper body and overlapping the strengthening skeleton with the front collision beam. However, this type of strengthening skeleton is only set in the middle of the front bumper body, and there are no other connection structures at the left and right ends, resulting in a relatively weak overall connection structure. Therefore, after driving for a period of time, there is still a situation where the front bumper assembly drops. Summary of the Utility Model
[0004] In view of this, the utility model provides a front bumper mounting assembly and a vehicle. By setting a front bumper strengthening skeleton inside the front bumper body and strengthening ribs on the front bumper strengthening skeleton, the structural strength of the flanging part of the front bumper body is strengthened and the front bumper body is supported to prevent the front bumper body from flipping; and by respectively setting mounting components for connecting with the vehicle body anti-collision beam at both ends of the inner side of the front bumper strengthening skeleton in the vehicle body width direction, the connection strength between the front bumper assembly and the vehicle body structure is strengthened to prevent the front bumper assembly from dropping due to insufficient connection strength.
[0005] The front bumper mounting assembly provided by the utility model includes a front bumper body and a front bumper strengthening skeleton installed inside the front bumper body. Mounting components for connecting with the vehicle body anti-collision beam are respectively arranged at both ends of the front bumper strengthening skeleton in the vehicle body width direction. The mounting components include a mounting bracket arranged on the front bumper strengthening skeleton and a connecting bracket arranged on the vehicle body anti-collision beam. After the mounting bracket and the connecting bracket overlap, they are connected and fixed through a connecting piece.
[0006] Furthermore, a flanging part connected to the vehicle body structure is formed by extending backward along the vehicle body length direction at the top of the front bumper body. A reinforcing rib in the same direction as the flanging part is formed on the inner side of the front bumper reinforcement frame in the vehicle body length direction, and the reinforcing rib is used to support the flanging part in the vehicle body height direction.
[0007] Furthermore, a front bumper lower grille installed below the front bumper reinforcement frame is further included. The top of the front bumper lower grille is snap-connected to the front bumper body and is fixedly connected to the front bumper reinforcement frame.
[0008] Furthermore, the upper end of the mounting bracket is fixedly connected to the front bumper reinforcement frame, and the lower end of the mounting bracket is fixedly connected to the front bumper lower grille.
[0009] Furthermore, the cross-section of the overlapping mating surface of the mounting bracket and the connecting bracket in the vehicle body width direction is a stepped structure.
[0010] Furthermore, the cross-section of the overlapping mating surface of the connecting bracket and the mounting bracket in the vehicle body width direction is an L-shaped structure.
[0011] Furthermore, the reinforcing rib is located outside the mounting assembly in the vehicle body width direction and extends from the top to the bottom of the front bumper reinforcement frame in the vehicle body height direction.
[0012] Furthermore, a first mounting hole is provided on the mounting surface of the mounting bracket, and a second mounting hole is provided on the mounting surface of the connecting bracket. The positions of the first mounting hole and the second mounting hole on the mounting surface are both triangularly distributed.
[0013] Furthermore, the distance between the two sets of mounting assemblies in the vehicle body width direction is set to be greater than two-thirds of the vehicle body width.
[0014] A vehicle is also provided, including the above-mentioned front bumper mounting assembly.
[0015] The beneficial effects of the present utility model are as follows: The front bumper mounting assembly provided by the present utility model strengthens the structural strength of the flanging part of the front bumper body and supports the front bumper body by arranging a front bumper reinforcing skeleton inside the front bumper body and arranging reinforcing ribs on the front bumper reinforcing skeleton, preventing the front bumper body from flipping; and by arranging mounting components for connecting with the vehicle body anti-collision beam at both ends in the vehicle body width direction inside the front bumper reinforcing skeleton, the connection strength between the front bumper assembly and the vehicle body structure is strengthened, preventing the front bumper assembly from dropping due to insufficient connection strength; after the mounting assembly is applied to the vehicle, it can effectively improve the structural strength of the front bumper itself, effectively ensure the DTS requirements of the whole vehicle front face during installation, and significantly strengthen the connection strength between the front bumper assembly and the vehicle body structure.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] As shown in the figure, the front bumper mounting assembly provided by the present utility model includes a front bumper body 1 and a front bumper reinforcement frame 2 installed inside the front bumper body 1. At both ends of the front bumper reinforcement frame 2 in the vehicle body width direction, there are respectively provided mounting components for connecting with the vehicle body anti-collision beam. The mounting components include a mounting bracket 3 provided on the front bumper reinforcement frame 2 and a connecting bracket 4 provided on the vehicle body anti-collision beam. After the mounting bracket 3 and the connecting bracket 4 are overlapped, they are connected and fixed by a connecting member 5. Among them, the front bumper reinforcement frame 2 is arranged inside the front bumper body 1 and is connected and fixed to the front bumper body 1 at multiple points by bolts. At the same time, the front bumper reinforcement frame 2 covers a large area inside the front bumper body 1, thereby improving the structural strength of the front bumper body 1 itself. The mounting components are composed of the mounting bracket 3 and the connecting bracket 4 that are overlapped and matched with each other. Among them, the mounting bracket 3 is provided on the front bumper reinforcement frame 2 and is connected and fixed to the front bumper reinforcement frame 2. The connecting bracket 4 is provided on the vehicle body anti-collision beam and is installed and fixed at the front end of the vehicle body anti-collision beam. After the mounting bracket 3 and the connecting bracket 4 are overlapped, they are finally connected and fixed by the connecting member 5 passing through both of them. The connecting member 5 can use screws or snaps. By respectively arranging mounting components for connecting with the vehicle body anti-collision beam at both ends of the inside of the front bumper reinforcement frame 2 in the vehicle body width direction, the connection strength between the front bumper assembly and the vehicle body structure is strengthened, and the requirements for supporting the front bumper are met, ensuring the stable performance of the front bumper and effectively preventing the front bumper from falling off.
[0025] In this embodiment, a flanging portion 6 for connecting with the vehicle body structure extends backward along the vehicle body length direction at the top of the front bumper body 1. An intensifying rib 7 in the same direction as the flanging portion 6 is formed inside the front bumper reinforcement frame 2 in the vehicle body length direction. The intensifying rib 7 is used to support the flanging portion 6 in the vehicle body height direction; combined Figure 1 、 Figure 2 and Figure 4 As shown, the flanging portion 6 at the top of the front bumper body 1 is mainly used to connect and fix with the front engine compartment structure on the vehicle body. Due to the structure, the overall strength of the connection between the flanging portion 6 and the front bumper body 1 is weak, and it is easy to break. Therefore, by setting the front bumper reinforcement frame 2 and the intensifying rib 7 on the front bumper reinforcement frame 2, the structural strength of the connection between the flanging portion 6 and the front bumper body 1 is strengthened, and the flanging portion 6 is supported in the vehicle body height direction. At the same time, the intensifying rib 7 can also prevent the front bumper body from flipping.
[0026] In this embodiment, it further includes a front bumper lower grille 8 installed below the front bumper reinforcement frame 2. The top of the front bumper lower grille 8 is snap-connected to the front bumper body 1 and is connected and fixed to the front bumper reinforcement frame 2; combined Figure 1 andFigure 4 As shown, the lower grille 8 of the front bumper is initially installed and positioned with the front bumper reinforcement frame 2 and the front bumper body 1 respectively by snap connection, and then is connected and fixed to the front bumper reinforcement frame 2 and the front bumper body 1 respectively by bolts, so as to strengthen the connection stability of the lower grille 8 of the front bumper. At the same time, compared with directly installing and fixing the lower grille 8 of the front bumper to the front bumper body 1, the installation is carried out through the cooperation of multiple components to adjust the installation gap between components, thereby ensuring the DTS requirements of the whole vehicle front face during installation.
[0027] In this embodiment, the upper end of the mounting bracket 3 is connected and fixed to the front bumper reinforcement frame 2, and the lower end of the mounting bracket 3 is connected and fixed to the lower grille 8 of the front bumper; combined Figure 3 As shown, the mounting bracket 3 is connected and fixed to the front bumper reinforcement frame 2 and the lower grille 8 of the front bumper respectively by bolts. And there is a connection structure between the lower grille 8 of the front bumper and the front bumper reinforcement frame 2 itself at the installation position of the mounting bracket 3. Therefore, the mounting bracket 3 can also strengthen the connection strength of the connection structure at this place.
[0028] In this embodiment, the cross-section of the overlapping mating surface between the mounting bracket 3 and the connecting bracket 4 in the vehicle body width direction is in a stepped structure; the cross-section of the overlapping mating surface between the connecting bracket 4 and the mounting bracket 3 in the vehicle body width direction is in an L-shaped structure; combined Figure 5 and Figure 6 As shown, the initial overlapping is realized in the form of mutual engagement between the mounting bracket 3 and the connecting bracket 4, and then the connection and fixation are realized through the connecting piece 5 penetrating through both of them; since the front bumper assembly needs to be overlapped on the vehicle body frame first and then connected and fixed during the later assembly process, the cross-section of the overlapping mating surface of the mounting bracket 3 in the vehicle body width direction is made into a stepped structure, and the cross-section of the overlapping mating surface on the connecting bracket 4 in the vehicle body width direction is made into an L-shaped structure, and the overlapping mating surface on the connecting bracket 4 is arranged at the end head in a U-shaped structure, so that the mounting bracket 3 and the connecting bracket 4 can perform initial overlapping mating during assembly, which is convenient for the workers to install quickly and improves the assembly efficiency.
[0029] In this embodiment, the reinforcing rib 7 is located outside the mounting assembly in the vehicle body width direction and extends from the top of the front bumper reinforcement frame 2 to the bottom of the front bumper reinforcement frame 2 in the vehicle body height direction; combined Figure 1 and Figure 4As shown, the position of the reinforcing rib 7 is mainly related to the installation and tightening points of the flanging part 6 and the vehicle body structure and the structural strength of the flanging part 6. Therefore, in this solution, the reinforcing rib 7 is arranged outside the installation component; and the reinforcing rib 7 extends from the top of the front bumper reinforcing skeleton 2 to the bottom of the front bumper reinforcing skeleton 2 in the vehicle body height direction, which is beneficial to improving the support strength of the front bumper reinforcing skeleton 2 for the flanging part in the vehicle body height direction.
[0030] In this embodiment, a first mounting hole 9 is provided on the mounting surface of the mounting bracket 3, and a second mounting hole 10 is provided on the mounting surface of the connecting bracket 4. The positions of the first mounting hole 9 and the second mounting hole 10 on the mounting surface are both triangularly distributed; combined with Figure 3 and Figure 4 as shown, the mounting surfaces of the mounting bracket 3 and the connecting bracket 4 are both connected and fixed by bolts; the first mounting hole 9 on the mounting surface of the mounting bracket 3 and the second mounting hole 10 on the mounting surface of the connecting bracket 4 are both triangularly distributed to improve the stability and connection strength of the mounting bracket 3 and the connecting bracket 4 during installation.
[0031] In this embodiment, the distance between the two groups of the mounting components in the vehicle body width direction is set to be greater than two-thirds of the vehicle body width; combined with Figure 1 and Figure 4 as shown, when the front bumper assembly is installed, the upper part of the flanging part 6 is connected to the front engine compartment frame of the vehicle body, and the middle and lower parts are mainly connected and fixed by the mounting components. Therefore, in order to ensure the stability between the front bumper assembly and the front engine compartment frame of the vehicle body, it is necessary to set the distance between the mounting components in the vehicle body width direction to be greater than two-thirds of the vehicle body width.
[0032] This embodiment also provides a vehicle, including the above-mentioned front bumper mounting assembly; after this mounting assembly is applied to the vehicle, it can effectively improve the structural strength of the front bumper itself, effectively ensure the DTS requirements of the whole vehicle front face during installation, and significantly strengthen the connection strength between the front bumper assembly and the vehicle body structure.
