DETAILED DESCRIPTION

[0036] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0037] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but merely as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0038] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0039] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0040] It should also be understood that although the present application has been described with reference to certain specific examples, those skilled in the art will be able to implement many other equivalent forms of the present application that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0041] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0042] Specific embodiments of the present application will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments described are merely examples of the present application and may be implemented in a variety of ways. Familiar and / or repetitive functions and structures are not described in detail to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details described herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to variously utilize the present application with substantially any suitable detailed structure.

[0043] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0044] Figures 2 to 9 The schematic diagram of the bumper mounting structure provided in the embodiment of the present application is shown. Figures 2 to 9 As shown, the first embodiment of the present application provides a bumper mounting structure, including a mounting bracket 1 connected between the bumper 10 and the body sheet metal 20, one end of the mounting bracket 1 is connected to the middle and lower part of the bumper 10, and the other end of the mounting bracket 1 extends along the length direction of the vehicle to the bottom of the body sheet metal 20.

[0045] The bumper 10 may be a front bumper or a rear bumper, and the mounting bracket 1 is connected between the front bumper and the front panel, or the mounting bracket 1 is connected between the rear bumper and the rear panel.

[0046] One end of the mounting bracket 1 is connected to the middle and lower part of the bumper 10, and the other end extends to be connected to the bottom of the body sheet metal 20, which can reduce the cavity area of the first energy absorption cavity 40 formed by the bumper 10, the mounting bracket 1 and the body sheet metal 20, thereby improving the supporting strength of the bumper 10, improving the vehicle assembly strength of the bumper assembly and improving the bumper driving mode. In addition, the first energy absorption cavity 40 can be used to effectively absorb energy to ensure vehicle driving safety.

[0047] In some embodiments, a height D of the mounting bracket 1 from the bottom of the bumper 10 is 1 / 3 to 1 / 2 of a height H of the bumper 10 .

[0048] like Figure 5As shown, the height D1 between the top of the mounting bracket 1 and the bottom of the bumper 10 is 1 / 2H, and the height D2 between the bottom of the mounting bracket 1 and the bottom of the bumper 10 is 1 / 3H. This avoids the mounting bracket 1 from being too low, resulting in the cavity area of the first energy absorption cavity 40 being too large and the modal improvement of the bumper 10 being not obvious; at the same time, it also avoids the mounting bracket 1 from being too high, resulting in the lower part of the bumper 10 being suspended too much and the lower part being insufficiently strong.

[0049] It should be noted that, in the following embodiments, the X direction refers to the vehicle length direction (vehicle front-to-back direction), the Y direction refers to the vehicle width direction (vehicle left-to-right direction), and the Z direction refers to the vehicle height direction.

[0050] In some embodiments, as Figures 5 to 9 As shown, a first slot 2 is provided on the bumper 10 , and one end of the mounting bracket 1 is engaged in the first slot 2 to improve the connection strength between the two, and the other end of the mounting bracket 1 is used to connect to the body sheet metal 20 .

[0051] One end of the mounting bracket 1 can be provided with a connecting portion 11 specifically engaged with the first slot 2. The connecting portion 11 is integrally engaged in the first slot 2. The top and bottom walls of the first slot 2 can limit the connecting portion 11 in the Z direction, thereby improving the supporting strength of the bumper 10.

[0052] Furthermore, a support member 111 is provided on a side of the mounting bracket 1 facing the first slot 2 and abutting against the first slot 2. The support member 111 is provided on a side of the connecting portion 11 facing the first slot 2.

[0053] A plurality of support members 111 are provided on one side of the connecting portion 11 facing the first slot 2 . The plurality of support members 111 are spaced apart along the Z direction of the vehicle to effectively support the first slot 2 while reducing the overall weight of the connecting portion 11 .

[0054] In some embodiments, a first limiting portion 21 is provided at the notch of the first slot 2 toward the connecting portion 11 . The first limiting portion 21 is provided at the upper and lower sides of the notch to limit the connecting portion 11 in the X direction and improve the X-direction support strength of the bumper 10 .

[0055] In some embodiments, as Figure 8 and Figure 9 As shown, the connecting portion 11 is provided with a second limiting portion 112 on a first side (eg, the left side) along the Y direction of the vehicle to limit the first card slot 2 in the Y direction.

[0056] The connecting portion 11 and the first slot 2 can limit each other from different directions through the second limiting portion 112, the inner wall of the first slot 2, and the first limiting portion 21 on the first slot 2, thereby improving the connection strength and connection reliability between the two, and thereby improving the supporting strength of the bumper assembly.

[0057] Furthermore, the second limiting portion 112 is formed by extending upward from the top of the connecting portion 11 , and / or the second limiting portion 112 is formed by extending downward from the bottom of the connecting portion 11 .

[0058] In this embodiment, the top and bottom of the connecting portion 11 are respectively provided with second limiting portions 112 to effectively limit the left or right side of the first card slot 2 .

[0059] In some embodiments, as Figure 6 、 Figure 8 and Figure 9 As shown, the connecting part 11 is provided with a second card slot 113 on the second side along the Y direction of the vehicle, and the first card slot 2 is provided with a card protrusion 22 that is engaged with the second card slot 113. After the connecting part 11 is engaged with the first card slot 2, the second card slot 113 can be reliably engaged with the card protrusion 22 in the first card slot 2, further improving the connection strength between the two.

[0060] Optionally, the connecting portion 11 is provided with a protrusion 114 protruding toward the first slot 2 along the second side edge of the vehicle in the Y direction, and a second slot 113 is formed between the protrusion 114 and one side of the support member 111. While ensuring the connection strength between the two, the side wall of the snap-fit protrusion 22 can be used to limit the support member 111 in the Y direction, thereby limiting the connecting portion 11 in the Y direction.

[0061] Furthermore, a first guide portion 115 is provided on an edge of the connecting portion 11 close to the second slot 113 to facilitate the connection and guidance between the connecting portion 11 and the first slot 2 .

[0062] In this embodiment, the first guide portion 115 is an inclined guide surface provided on the outer edge of the protruding portion 114 , and has a simple structure and a reasonable arrangement.

[0063] In some embodiments, as Figure 6 As shown, a second guide portion 23 is provided at the front end of the clamping protrusion 22. The second guide portion 23 can be an arc-shaped guide portion provided at the connection between the front end of the clamping protrusion 22 and the side wall, or an inclined guide surface provided at the front end of the clamping protrusion 22.

[0064] The mounting bracket 1 further includes a support portion 12 extending from the connecting portion 11 toward the vehicle body sheet metal 20 . The support portion 12 is connected to the vehicle body sheet metal 20 via the L-shaped bracket 3 .

[0065] The L-shaped bracket 3 is disposed at the end of the support portion 12 , with one side wall of the L-shaped bracket 3 welded or screwed to the vehicle body sheet metal 20 , and the other side wall of the L-shaped bracket 3 welded to the support portion 12 .

[0066] Preferably, the L-shaped bracket 3, serving as a vehicle body connection bracket, is pre-welded to the vehicle body sheet metal 20 and then screwed to the support portion 12 via bolts 5. This facilitates installation of the bumper 10 on the vehicle body. Furthermore, a larger welding area can be provided between the L-shaped bracket 3 and the vehicle body sheet metal 20 to increase the connection strength between the two, thereby increasing the connection strength between the bumper 10 and the vehicle body sheet metal 20. The connection area between the L-shaped bracket 3 and the support portion 12 can also be provided larger to increase the connection strength between the two, thereby increasing the overall support strength of the bumper assembly.

[0067] In this embodiment, the length of the L-shaped bracket 3 can be set to be relatively short. The mounting bracket 1 and the L-shaped bracket 3 securely connect the bumper 10 to the vehicle body sheet metal 20. This avoids the problem in the prior art where the bumper 10 is connected to the vehicle body sheet metal 20 using a longer L-shaped bracket 3. This results in weak support strength (softness) when the bumper 10 is pressed, leading to poor overall vehicle assembly strength and driving performance. The mounting bracket 1 is positioned in the middle region of the bumper 10, effectively improving the support strength in this region.

[0068] In some embodiments, the support portion 12 is provided with reinforcements to increase the support strength of the support portion 12. The reinforcements are arranged in different directions on the support portion 12, thereby increasing the support strength of the support portion 12 in different directions. The reinforcements are provided on the upper and lower sides of the support portion 12 to further increase the support strength of the support portion 12.

[0069] In some embodiments, as Figure 8 and Figure 9 As shown, the reinforcement includes multiple first reinforcements 121 and multiple second reinforcements 122. The first reinforcement 121 is arranged near the connecting portion 11. The first reinforcement 121 is a longitudinal reinforcement extending along the vehicle X direction, and multiple longitudinal reinforcements are arranged at intervals along the vehicle Y direction; the second reinforcement 122 is a transverse reinforcement extending along the vehicle Y direction, and multiple transverse reinforcements are connected in sequence along the vehicle X direction, and there is an angle between adjacent transverse reinforcements.

[0070] Multiple longitudinal reinforcements located near the connecting portion 11 effectively strengthen the connection between the connecting portion 11 and the support portion 12. Multiple transverse reinforcements are sequentially folded back and connected between the lateral sides of the support portion 12, thereby reinforcing different locations of the support portion 12 along the vehicle's X-axis. These multiple transverse reinforcements are sequentially connected to ensure the overall support reliability of the support portion 12. The first reinforcement 121 and the second reinforcement 122 are preferably vertically arranged reinforcing ribs.

[0071] like Figures 7 to 9As shown, the support portion 12 is provided with a bracket mounting position 123 for mounting the L-shaped bracket 3 at one end close to the vehicle body sheet metal 20 , and a mounting hole 124 for mounting the bolt 5 is opened on the bracket mounting position 123 .

[0072] In some embodiments, the bumper 10 includes an upper bumper 101 and a lower bumper 102 connected up and down, the lower part of the upper bumper 101 is connected to the upper part of the lower bumper 102, and the lower part of the upper bumper 101 is provided with a connecting frame 4, one side of the connecting frame 4 (for example, the rear side) is connected to the lower bumper 102, and the other side of the connecting frame 4 (for example, the front side) is provided with a first card slot 2, which facilitates the connection between the bumper 10 and the mounting bracket 1 and facilitates the positioning of the installation position of the mounting bracket 1.

[0073] The connecting frame 4 is provided with a first engaging position 41, and the lower bumper 102 is provided with a first engaging member 1021 engaged with the first engaging position 41. The first engaging position 41 is a engaging hole or an engaging groove.

[0074] In some embodiments, as Figure 5 As shown, a second clamping member 1023 is further provided on the top of the lower bumper 102, and a second clamping position 1011 is provided in the middle of the upper bumper 101 to be clamped with the second clamping member 1023, thereby ensuring a reliable connection between the upper and lower bumpers.

[0075] In this embodiment, Figure 5 and Figure 7 As shown, the first engaging position 41 is a first engaging hole. The end of the first engaging member 1021 is provided with a first engaging portion 1022. The back side of the first engaging hole is provided with a second engaging portion 411. After the first engaging member 1021 passes through the first engaging hole, the first engaging portion 1022 and the second engaging portion 411 engage with each other, thereby reliably connecting the bottom of the upper bumper 101 and the lower bumper 102. In this case, the size of the first engaging member 1021 can be set to be smaller than the first engaging hole to facilitate positioning of the two during assembly. In other embodiments, the size of the first engaging member 1021 can also match the size of the first engaging hole, and the two can be plugged together. However, positioning the two during assembly may require time.

[0076] like Figure 4 and Figure 6As shown, the connecting frame 2 is arranged at the bottom of the upper bumper 101 and connected to the lower bumper 102. The connecting frame 2 is connected to the body sheet metal 20 through the mounting bracket 1 and the L-shaped bracket 3. Compared with the prior art, the bottom of the bumper 10 (the bottom of the lower bumper 102) is connected to the body sheet metal 20. The Z-direction distance between the upper mounting point and the bottom mounting point of the bumper 10 is large, and a large area of the cavity between the bumper 10 and the body sheet metal 20 is unsupported. The present application can reduce the area of the cavity enclosed by the bumper 10, the mounting bracket 1, the L-shaped bracket 3 and the body sheet metal 20, which can greatly improve the connection strength between the bumper 10 and the body sheet metal 20 and improve the support strength of the bumper 10.

[0077] Optional, such as Figure 6 and Figure 7 As shown, a third reinforcement 24 is connected between the upper bumper 101 and the top of the connecting frame 2 to improve the overall strength of the upper bumper 101 and the connecting frame 2. The third reinforcement 24 is preferably a triangular rib. The upper bumper 101 and the connecting frame 2 can be an integrally formed structure.

[0078] In some embodiments, the connecting frame 4 is connected to the lower bumper 102 to form a second energy absorbing cavity 50 , which can absorb energy from the lower area of the mounting bracket 1 to ensure the collision performance of the vehicle.

[0079] There are multiple mounting brackets 1, which are spaced apart along the width direction of the vehicle. The connecting brackets 4 are arranged one-to-one corresponding to the mounting brackets 1 along the width direction of the upper bumper 101. Each connecting bracket 4 is provided with a first card slot 2, which can reliably support the middle area of the bumper along the Y direction of the vehicle.

[0080] In some embodiments, as Figure 5 As shown, the bumper 10 further includes a trim panel 60 disposed at the lower portion of the bumper 10. The trim panel 60 is connected to the lower bumper 102, and a third energy-absorbing cavity 70 is formed therebetween to ensure support strength and collision performance near the bottom of the lower bumper 102. A second embodiment of the present application provides a vehicle including the aforementioned bumper mounting structure. The vehicle corresponds to the bumper mounting structure of the aforementioned embodiment. Any optional features described in the bumper mounting structure embodiment are also applicable to the vehicle embodiment and will not be further described herein.

[0081] The vehicle may be a sedan, an off-road vehicle, a truck, etc. The bumper mounting structure may connect the rear bumper to the rear panel, or may connect the front bumper to the front panel.
