Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and in particular to a rear bumper mounting structure; meanwhile, the utility model also relates to a vehicle provided with the rear bumper mounting structure. Background Art

[0002] The rear bumper on a vehicle is an important safety device that protects the vehicle body, passengers and pedestrians, as well as serves as a decorative feature. In the event of a collision, the rear bumper can absorb and mitigate external impact forces, thereby protecting the vehicle body and passengers from direct injury. Through its internal buffer material and crossbeam structure, it disperses and transmits the collision force to other vehicle body structures, reducing the impact on the vehicle body and passengers. Especially in low-speed collision accidents, the rear bumper can play a good buffering role, protecting the front and rear vehicle bodies from serious damage.

[0003] The rear bumper is installed by installing an integrated mounting bracket in the left-right direction or the up-down direction of the vehicle. When installing the mounting bracket in the up-down direction of the vehicle, it is necessary to open primary and secondary positioning holes set in the up-down direction of the vehicle for positioning the mounting bracket. The mounting bracket is installed by inserting the buckles into the mounting holes in the up-down direction of the vehicle. However, the mounting structure of this bumper makes it easy for the side panel to produce a negative stamping angle problem. At the same time, in low-speed collision tests, the rear side panel is easily invaded, resulting in a reduced safety level. In order to avoid such problems, the problem is solved by moving the sharp corners of the shape forward, but this solution of moving the angle forward often requires sacrificing the shape.

[0004] In addition, when installing the mounting bracket along the left and right directions of the vehicle, the side panel metal needs to open primary and secondary positioning holes along the left and right directions of the vehicle for positioning the mounting bracket. After the mounting bracket is positioned by the positioning pin, the buckle is inserted into the mounting hole to complete the installation. This structure requires opening holes on the flange of the side panel outer plate, and the flange needs to be lengthened to meet the welding space requirements, which increases the height difference of the wheel cover in the left and right directions of the vehicle, which is prone to the risk of stamping cracking.

[0048] Embodiment 1

[0049] The present embodiment relates to a rear bumper mounting structure to solve the problem in the prior art that the rear bumper mounting structure is not designed properly, which results in the side outer panel 1 being easily stamped with negative angles and cracks, thus causing poor collision safety.

[0050] In terms of overall structure, the rear bumper mounting structure in this embodiment includes a first mounting bracket 2 and a second mounting bracket 3 provided at the rear end of the side outer panel 1. The rear end of the side outer panel 1 has a first extension portion 101 and a second extension portion 102. The first extension portion 101 extends downward along the vertical direction of the vehicle, and the second extension portion 102 extends toward the inner side of the vehicle along the left-right direction of the vehicle. The first mounting bracket 2 is mounted on the first extension portion 101 along the left-right direction of the vehicle, and the second mounting bracket 3 is mounted on the second extension portion 102 along the vertical direction of the vehicle.

[0051] The rear bumper mounting structure described in this embodiment, by installing the first mounting bracket 2 on the first mounting portion along the left and right sides of the whole vehicle, and installing the second mounting bracket 3 on the second extending portion 102 along the up and down direction of the whole vehicle, is not only conducive to the installation of the mounting bracket on the side panel, but also conducive to meeting the stamping requirements of the side panel outer panel 1, thereby facilitating the improvement of the safety of the side panel outer panel 1, and also enabling the shape of the sharp corners on the side panel outer panel 1 to be set rearward without moving forward, thereby facilitating the diversification of vehicle shapes.

[0052] Based on the above overall introduction, an exemplary structure of the rear bumper mounting structure described in this embodiment is as follows: Figure 1 and Figure 2 As shown in . The lower edge of the rear end of the side outer panel 1 is extended along the front-to-back direction of the vehicle, the first extension portion 101 is located at the front side of the lower edge of the rear end of the side outer panel 1, and the front end of the first extension portion 101 is connected to the wheel house outer panel 4. The second extension portion 102 is located at the rear side of the lower edge of the rear end of the side outer panel 1, and the first extension portion 101 and the second extension portion 102 are arranged at intervals in the front-to-back direction of the vehicle, so that the first mounting bracket 2 and the second mounting bracket 3 are arranged in coordination in the front-to-back direction of the vehicle, thereby further improving the installation effect of the rear bumper.

[0053] As a preferred embodiment, the first mounting bracket 2 in this embodiment is clamped on the first extension part 101. The first mounting bracket 2 is installed on the first extension part 101 by means of a clamping assembly method, which is not only easy to operate but also saves tedious preparation work and waiting time, thereby improving installation efficiency.

[0054] The structure of the first mounting bracket 2 is as follows Figure 3 and Figure 6As shown in the figure, three mounting openings 1013 are arranged at intervals along the front-rear direction of the vehicle on the first extension part 101, and the clamping parts are respectively installed at the corresponding mounting openings 1013. The first mounting bracket 2 is provided with clamping holes 205 arranged one-to-one corresponding to each mounting opening 1013. The first mounting bracket 2 is mounted on the first extension part 101 by clamping the clamping parts and the corresponding clamping holes 205.

[0055] In this embodiment, the first extension part 101 is installed and matched with the first mounting bracket 2, which can ensure that the side outer panel 1 and the wheel house outer panel 4 can meet the stamping requirements and ensure that there will be no negative stamping angle and cracking problems. In addition, the side outer panel positioning hole 1015 can also be set on the first extension part 101 to ensure the reliability of the installation and positioning of the side outer panel 1. As a preferred arrangement, the three mounting openings 1013 are arranged in a triangle, which can take advantage of the good stability of the triangle and help ensure the clamping stability of the first mounting bracket 2 on the first extension part 101.

[0056] It should be noted that the clamping member in this embodiment can be a product in the prior art, as long as it can be clamped and matched with the clamping hole 205 to meet the installation requirements of the first mounting bracket 2. For example, the free end of the clamping member has an elastic clamping head, and the clamping heads can be close to each other in the process of clamping into the clamping hole 205 and smoothly pass through the clamping hole 205, and after passing through the clamping hole 205, they are clamped on the outside of the first mounting bracket 2, so that the first mounting bracket 2 is confined in the space limited between the first extension portion 101 and the clamping head of the clamping member.

[0057] In order to improve the clamping efficiency of the first mounting bracket 2 on the first extension portion 101, as shown in FIG. Figure 6 As shown in , a first main positioning column 204 is provided at one end of the first mounting bracket 2, a first secondary positioning column 203 is provided at the other end, and a first main positioning hole 1011 and a first secondary positioning hole 1012 are provided on the first extension portion 101. The first mounting bracket 2 can be positioned on the first extension portion 101 by inserting the first main positioning column 204 in the first main positioning hole 1011 and the first secondary positioning column 203 in the first secondary positioning hole 1012, and the buckle can be inserted into the corresponding clamping hole 205 by moving from the outside to the inside along the left-right direction of the vehicle, thereby completing the installation of the first mounting bracket 2 on the first extension portion 101.

[0058] As a preferred embodiment, the second mounting bracket 3 in this embodiment is screwed to the second extension portion 102. The second mounting bracket 3 is installed by screwing, which has the advantage of facilitating the installation and maintenance of the second mounting bracket 3. In addition, the installation of the second mounting bracket 3 on the second extension portion 102 can also ensure that the side outer panel 1 is not invaded by low-speed collisions, and solve the stamping problem of the side outer panel 1, so that the sharp corner position of the shape does not need to be moved toward the front of the vehicle to meet the production technology requirements, ensuring the diversification of the shape.

[0059] In terms of specific structure, Figure 4 , Figure 7 and Figure 8 As shown in , three projection welding nuts are arranged at intervals along the length direction of the second extension part 102 on the second extension part 102, and mounting holes 1023 are respectively provided on the second extension part 102 corresponding to each projection welding nut. Through holes 307 corresponding to each mounting hole 1023 are respectively provided on the second mounting bracket 3, and bolts are passed through the through holes 307 and the corresponding mounting holes 1023 and are threadedly connected with the corresponding projection welding nuts, so that the second mounting bracket 3 is installed on the second extension part 102. Among them, the projection welding nuts are waterproof projection welding nuts to ensure their sealing.

[0060] The three mounting holes 1023 in this embodiment are preferably arranged in a triangle, so that the triangle can be used to have good stability, which is conducive to ensuring the screw connection stability of the second mounting bracket 3 on the second extension portion 102. In addition, in order to improve the structural strength of the through hole 307, the second mounting bracket 3 is provided with annular reinforcing ribs arranged along the circumference of the through hole 307 and protruding from both sides of the thickness of the second mounting bracket 3.

[0061] As a preferred embodiment, a hook portion is provided between the second mounting bracket 3 and the second extension portion 102 in this embodiment, and the hook portion can pre-position the second mounting bracket 3 on the second extension portion 102. The installation station at the second extension portion 102 is a low station, and the installation worker cannot directly see and needs to squat to operate. The provision of the hook portion facilitates the pre-positioning of the second mounting bracket 3 on the second extension portion 102, which can improve the worker's operating convenience and installation efficiency.

[0062] In terms of specific structure, Figure 4 and Figure 7 As shown in , the hooking portion includes a hook body 305 provided on the second mounting bracket 3, and a hooking hole 1024 provided on the second extension portion 102. There are two hook bodies 305 arranged opposite to each other, and the hooking holes 1024 are arranged one by one corresponding to the hook bodies 305. In this embodiment, the structures of the hook body 305 and the hooking hole 1024 are simple, easy to arrange and implement, and the hooking and matching effect of the two is good.

[0063] In detail, the hook hole 1024 is arranged on the second extension part 102 close to the mounting hole 1023 in the middle, and the free ends of the two hook bodies 305 are provided with hook heads that are convex, and the hook heads are provided with guide surfaces that are inclined. The guide surfaces on the two hook heads can abut against the side walls of the hook hole 1024, so that the free ends of the two hook bodies 305 are close to each other and penetrate into the hook hole 1024, and after the two hook heads completely pass through the hook holes 1024, the two hook bodies 305 can be reset and the hook heads are hooked on the inner side of the second extension part 102, thereby completing the pre-positioning of the second mounting bracket 3 on the second extension part 102.

[0064] In addition, in order to improve the pre-positioning effect of the second mounting bracket 3 on the second extension portion 102, as shown in FIG. Figure 7 As shown in , a second main positioning column 304 is provided at one end of the second mounting bracket 3, a second secondary positioning column 303 is provided at the other end, and a second main positioning hole 1021 and a second secondary positioning hole 1022 are provided on the second extension portion 102. The second mounting bracket 3 can be positioned on the second extension portion 102 by inserting the second main positioning column 304 in the second main positioning hole 1021 and the second secondary positioning column 303 in the second secondary positioning hole 1022, and the second mounting bracket 3 is moved from bottom to top along the up-down direction of the vehicle, so that the bolts and the corresponding projection welding nuts are screwed together, thereby completing the installation of the second mounting bracket 3 on the second extension portion 102.

[0065] In this embodiment, in order to improve the performance of the installation structure, Figure 6 and Figure 8 As shown in the figure, a plurality of first reinforcing ribs 206 are respectively provided on the side of the first mounting bracket 2 away from the first extension portion 101, and a plurality of second reinforcing ribs 306 are respectively provided on the side of the second mounting bracket 3 away from the second extension portion 102. The first reinforcing ribs 206 and the second reinforcing ribs 306 each include a first portion extending in the thickness direction of the extension portion and in a cylindrical shape, and a plurality of second portions spaced apart along the circumference of the first portion, and the plurality of second portions are radially arranged along the radial direction of the first portion. Of course, in specific implementation, the structural form of the reinforcing ribs can still be determined according to the use requirements.

[0066] As a feasible implementation, the first mounting bracket 2 and the second mounting bracket 3 in this embodiment are injection molded. This is conducive to the price molding of each mounting bracket, and has the advantages of low processing cost and good modeling effect. In addition, the injection molded mounting bracket is also conducive to the lightweight design of the vehicle. Of course, the solution of injection molding only one of the first mounting bracket 2 and the second mounting bracket 3 is also feasible.

[0067] In this embodiment, the first mounting bracket 2 and the second mounting bracket 3 are provided with a clamping portion, and the clamping portion is used to be clamped and connected with the rear bumper. Here, the clamping portion is clamped and connected with the rear bumper, which is conducive to improving the installation convenience of the rear bumper. Figure 5 As shown in , the clamping portion on the first mounting bracket 2 is arranged at the top of the first mounting bracket 2, and the clamping portion specifically includes a plurality of first clamping heads 201 arranged at intervals along the length direction of the first mounting bracket 2, and the plurality of first clamping heads 201 are extended outwardly along the thickness direction of the first mounting bracket 2. The rear bumper is provided with first clamping holes arranged one-to-one corresponding to the plurality of first clamping heads 201.

[0068] Here, the rear bumper can be mounted on the first mounting bracket 2 by engaging the first clamping head 201 with the corresponding first clamping hole. In addition, a plurality of first limiting pieces 202 are arranged at intervals along the length direction of the first mounting bracket 2 on the top of the first mounting bracket 2. The plurality of first limiting pieces 202 and the plurality of first clamping heads 201 are arranged alternately in the length direction of the first mounting bracket 2. The first limiting piece 202 is "L"-shaped, and the vertical portion of the first limiting piece 202 is connected to the first mounting bracket 2, and the horizontal portion extends to the outside of the first mounting bracket 2. The first limiting piece 202 can abut against the top of the rear bumper, thereby limiting the upward displacement of the rear bumper in the installed state.

[0069] Reference Figure 7 As shown in , the clamping portion on the second mounting bracket 3 is arranged on the outer side of the top of the second mounting bracket 3, and the clamping portion specifically includes a plurality of second clamping heads 301 arranged at intervals along the length direction of the second mounting bracket 3, and the plurality of second clamping heads 301 are extended to the outer side of the second mounting bracket 3. The rear bumper is provided with second clamping holes arranged one-to-one corresponding to the plurality of second clamping heads 301.

[0070] Here, the rear bumper can be mounted on the second mounting bracket 3 by engaging the second clamping head 301 with the corresponding second clamping hole. In addition, a plurality of second limiting pieces 302 are arranged at intervals along the length direction of the second mounting bracket 3 on the top of the second mounting bracket 3. The plurality of second limiting pieces 302 and the plurality of second clamping heads 301 are arranged alternately in the length direction of the second mounting bracket 3. The second limiting piece 302 is "L"-shaped, and the vertical portion of the second limiting piece 302 is connected to the second mounting bracket 3, and the horizontal portion extends to the outside of the second mounting bracket 3. The second limiting piece 302 can abut against the top of the rear bumper, thereby limiting the upward displacement of the rear bumper in the installed state.

[0071] It is understandable that in this embodiment, it is also feasible to provide a clamping portion on one of the first mounting bracket 2 and the second mounting bracket 3. In this case, the mounting bracket without a clamping portion can be connected to the rear bumper using other connection methods as long as the usage requirements are met.

[0072] The rear bumper mounting structure described in this embodiment adopts a first mounting bracket 2 and a second mounting bracket 3 to be installed and matched in different installation directions, so that the side outer panel 1 can meet the production technology and safety performance requirements. At the same time, it can also move the sharp corner of the rear end of the side outer panel 1 backward, which is conducive to meeting different styling requirements, so as to achieve a more diversified vehicle appearance and enhance the competitiveness of the vehicle model.
