[0029] This utility model provides a rear bumper mounting structure and vehicle, which can reduce the processing difficulty of the rear bumper body and prevent water accumulation. The following detailed description is provided with reference to specific embodiments.

[0030] like Figure 1 and Figure 2 As shown in the figure, the rear bumper mounting structure provided by this utility model includes a rear bumper body 1 and a mounting bracket 2; the top of the rear bumper body 1 is provided with a first structural wall 11; the mounting bracket 2 is located on the front side of the rear bumper body 1, and the top of the mounting bracket 2 is provided with a second structural wall 21 connected to the first structural wall 11, and the second structural wall 21 and the first structural wall 11 together form a groove 4 adapted to the rotation trajectory 31 of the door 3.

[0031] It should be noted that the mounting bracket 2 can follow the contour of the rear bumper body 1 in the left-right direction of the vehicle. Figure 1 Extending along the Y-axis (as shown), both the second structural wall 21 and the first structural wall 11 extend along the left-right direction of the vehicle to form a groove 4 that adapts to the rotation trajectory 31 of the ground door 3. Specifically, the shapes of the second structural wall 21 and the first structural wall 11 are not limited; for example, they can be arc-shaped or bent. For the second structural wall 21 and the first structural wall 11 to jointly form the groove 4, it means that the second structural wall 21 and the first structural wall 11 respectively constitute different wall portions of the groove 4. For example, the first structural wall 11 constitutes the bottom wall and rear side wall of the groove 4, and the second structural wall 21 constitutes the front side wall of the groove 4. Or, for another example, the first structural wall 11 constitutes the rear side wall of the groove 4, and the second structural wall 21 constitutes the bottom wall and front side wall of the groove 4. The terms "front" and "rear" can be referenced... Figure 2The X-axis direction is shown. Specifically, the rotation trajectory 31 of the ground door 3 can be the rotation trajectory of the lower end of the ground door 3.

[0032] In this embodiment, since the first structural wall 11 at the top of the rear bumper body 1 is connected to the second structural wall 21 at the top of the mounting bracket 2 and together form the groove 4, that is, the groove 4 is spliced ​​together from two parts belonging to the rear bumper body 1 and the mounting bracket 2 respectively. Compared with the groove 4 being constructed entirely on the rear bumper body 1, the surface shape complexity of the rear bumper body 1 can be relatively reduced, thereby reducing the processing difficulty of the rear bumper body 1. In addition, since the first structural wall 11 and the second structural wall 21 are two independent structures, the connection between the two can realize the drainage function. After water enters the groove 4, it can flow out through the connection between the first structural wall 11 and the second structural wall 21, thereby avoiding water accumulation.

[0033] Optionally, such as Figure 2 , Figure 3 and Figure 4 As shown, the second structural wall 21 includes a first wall portion 211 and a second wall portion 212. The first wall portion 211 is horizontally arranged, and the second wall portion 212 is connected to the front end of the first wall portion 211 and is arranged at an angle to the first wall portion 211. The first structural wall 11 is connected to the rear end of the first wall portion 211 and is arranged at an angle to the first wall portion 211.

[0034] Specifically, the first wall portion 211 and the second wall portion 212 can be an integral structure for easy processing and forming. Additionally, it should be noted that in this embodiment, "horizontally arranged" means roughly horizontally positioned, with a small angle of inclination relative to the horizontal plane; "angled arrangement" means that the two are not parallel and have a certain angle of inclination.

[0035] In this optional embodiment, the first wall portion 211 is horizontally arranged, the second wall portion 212 is connected to the front end of the first wall portion 211, and the first structural wall 11 is connected to the rear end of the first wall portion 211. Thus, the first wall portion 211 forms the bottom wall of the groove 4, the second wall portion 212 forms the front side wall of the groove 4, and the first structural wall 11 forms the rear side wall of the groove 4. That is to say, the connection between the first structural wall 11 and the second structural wall 21 is exactly located at the intersection of the bottom wall and the rear side wall of the groove 4, which makes it easier for water to drain. Furthermore, the first structural wall 11 is only used to form one side wall of the groove 4, which can further reduce the processing difficulty of the rear bumper body 1.

[0036] Optionally, such as Figure 4 As shown, the first structural wall 11 and / or the second wall portion 212 gradually slope downwards in the direction toward the first wall portion 211.

[0037] It should be noted that "and / or" represents three options: first, the first structural wall 11 gradually slopes downwards in the direction towards the first wall portion 211; second, the second wall portion 212 gradually slopes downwards in the direction towards the first wall portion 211; and third, both the first structural wall 11 and the second wall portion 212 gradually slope downwards in the direction towards the first wall portion 211. This invention can choose any one of these three options, and no limitation is made here. Specifically, when both the first structural wall 11 and the second wall portion 212 gradually slope downwards in the direction towards the first wall portion 211, the resulting groove 4 is approximately a funnel shape with its opening facing upwards.

[0038] In this optional embodiment, by gradually tilting the first structural wall 11 and / or the second wall portion 212 downward in the direction toward the first wall portion 211, the opening of the enclosed groove 4 can be made larger, and the shape of the groove tends to be arc-shaped, so that it can better fit the rotation trajectory 31 of the ground door 3. While avoiding the rotation trajectory 31 of the ground door 3, the gap 5 between the groove wall surface of the groove 4 and the ground door 3 can be relatively reduced, which helps to improve the aesthetics.

[0039] Furthermore, the first structural wall 11 and / or the second wall portion 212 may also be curved in an arc shape so that the overall groove shape is closer to an arc surface.

[0040] Optionally, such as Figure 4 and Figure 5 As shown, a gap 5 is formed between the first wall portion 211 and the first structural wall 11 in the front-rear direction.

[0041] Specifically, gap 5 is a strip-shaped gap extending left and right, penetrating the bottom of groove 4 to facilitate the rapid drainage of water from groove 4. In addition, the width of gap 5 can be about 2mm. At this width, gap 5 is neither too small to affect drainage nor too large to affect aesthetics.

[0042] In this optional embodiment, the gap 5 formed between the first wall portion 211 and the first structural wall 11 in the front-rear direction can allow water to pass through, so as to help water drain quickly and improve the smoothness of drainage.

[0043] Furthermore, the first wall portion 211 is inclined downward from front to back, so that the rear end of the first wall portion 211 is lower than the front end, which facilitates the flow of water in the groove 4 to the gap 5 and out of the gap 5.

[0044] Optionally, such as Figure 4 and Figure 5As shown, the rear bumper mounting structure also includes a first water guide 12, which is located below the gap 5. One end of the first water guide 12 is connected to the first structural wall 11, and the other end of the first water guide 12 extends to the bottom of the first wall 211.

[0045] Specifically, a gap is formed between the upper end face of the first water guiding part 12 and the lower end face of the first wall part 211 to allow water to flow through.

[0046] In this optional embodiment, by providing a first water guiding part 12 below the gap 5, with one end of the first water guiding part 12 connected to the first structural wall 11 and the other end extending to the lower part of the first wall 211, the first water guiding part 12 can guide the water flow. After the water flows through the gap 5, it can flow along the upper surface of the first water guiding part 12 to the lower part of the first wall 211, so as to avoid the water from dripping directly down through the gap 5 and causing abnormal noise. In addition, the first water guiding part 12 can also shield the gap 5, preventing direct visibility into the gap 5, thereby improving the aesthetics.

[0047] Optionally, such as Figure 4 and Figure 5 As shown, the rear bumper mounting structure also includes a second water guide 22, which is located below the first water guide 12. The front end of the second water guide 22 bypasses the front end of the first water guide 12 and connects to the first wall portion 211.

[0048] Specifically, the second water guide section 22 and the first wall section 211 can be an integral structure. A gap is formed between the second water guide section 22 and the first water guide section 12 to allow water to flow through. In addition, a third reinforcing rib 25 can be provided at the lower end of the second water guide section 22 to improve the strength of the second water guide section 22. In this optional embodiment, by providing the second water guide section 22 below the first water guide section 12, and the front end of the second water guide section 22 bypassing the front end of the first water guide section 12 and connecting with the first wall section 211, the second water guide section 22 can also guide the water flow. After the water flows out from the upper end surface of the first water guide section 12, it can flow to the second water guide section 22 and flow down along the second water guide section 22, ultimately making the drainage path of the water flow below the gap 5 a U-shaped path. This can improve the guiding effect of the water flow and further improve the abnormal noise generated by drainage.

[0049] Optionally, such as Figure 4 As shown, the mounting bracket 2 further includes a first reinforcing rib 23, which includes a horizontal section 231 connected to the front end of the first wall portion 211 and a vertical section 232 connected to the front end of the horizontal section 231.

[0050] Specifically, the horizontal segment 231 is horizontally positioned, and the vertical segment 232 is vertically positioned. The horizontal segment 231, the vertical segment 232, and the first wall portion 211 can be an integrated structure for easy processing and forming. The first reinforcing rib 23 can be a strip structure extending in the left-right direction to enhance the structural strength of the mounting bracket 2.

[0051] In this optional embodiment, the first reinforcing rib 23 is formed by connecting a horizontal segment 231 and a vertical segment 232 in the front-back direction, making the first reinforcing rib 23 a bent structure as a whole. In this way, while improving the structural strength of the first wall portion 211, the front-back dimensions of the mounting bracket 2 are not excessively increased. In addition, when the reinforcing rib is injection molded on one side of the plate, a shrinkage mark may be formed on the other side of the plate, thus affecting the appearance. In this embodiment, the first reinforcing rib 23 is connected to the front end of the first wall portion 211 through the horizontal segment 231. That is, the first reinforcing rib 23 is formed at the corner where the first wall portion 211 and the second wall portion 212 are connected, rather than on the back of the first wall portion 211 or the second wall portion 212. This avoids the formation of a shrinkage mark on the front side (the side forming the groove) of the first wall portion 211 or the second wall portion 212, thereby avoiding affecting the appearance. Furthermore, by forming a first reinforcing rib 23 at the connection between the first wall portion 211 and the second wall portion 212, the connection between the first wall portion 211 and the second wall portion 212 can be strengthened, thereby effectively improving the structural strength of the second structural wall 21.

[0052] Optionally, such as Figure 4 As shown, the bottom surface of the first wall portion 211 is provided with a second reinforcing rib 24, and the thickness of the second reinforcing rib 24 is less than the thickness of the first reinforcing rib 23.

[0053] Specifically, the bottom (back) surface of the first wall portion 211 may be provided with a plurality of second reinforcing ribs 24, each of which may be a strip structure extending in the left-right direction, and the plurality of second reinforcing ribs 24 may be arranged sequentially at intervals in the front-back direction. The second reinforcing ribs 24 and the first wall portion 211 may also be an integral structure for easy processing and forming.

[0054] In this optional embodiment, during injection molding, the second reinforcing rib 24 may form a shrinkage mark on the top surface (front) of the first wall portion 211, affecting the appearance. Therefore, this solution sets the thickness of the second reinforcing rib 24 to be less than the thickness of the first reinforcing rib 23. Compared with the second reinforcing rib 24 having the same or greater thickness as the first reinforcing rib 23, the shrinkage mark formed on the top surface of the first wall portion 211 can be avoided or improved, thereby improving the aesthetics.

[0055] Optionally, such as Figure 4As shown, the mounting bracket 2 also includes a vertical plate 26 connected to the upper end of the second structural wall 21. The vertical plate 26 is vertically arranged, and a threaded sleeve 27 is provided on the side of the vertical plate 26 facing the rear bumper body 1. The end of the threaded sleeve 27 away from the vertical plate 26 is closed.

[0056] Specifically, the upright plate 26 and the second structural wall 21 can be an integrated structure for easy processing and forming. The upright plate 26 is generally vertically arranged to facilitate connection to the vehicle body via bolts. There are no restrictions on the specific implementation of the closed-end configuration of the threaded sleeve 27. For example, the threaded hole in the threaded sleeve 27 can be a blind hole to close one end of the threaded sleeve 27; or, for example, a sealing plate can be welded to one end of the threaded sleeve 27 to close that end. Furthermore, through holes 261 can be formed in the front and rear opposite portions of the upright plate 26 and the threaded sleeve 27. The through holes 261 are coaxial with the threaded sleeve 27, allowing the vehicle body to be bolted to the threaded sleeve 27 through the holes 261, thus connecting the vehicle body and the upright plate 26. Additionally, the two ends of the upright plate 26 along the left-right direction of the vehicle can be connected to the two ends of the rear bumper body 1 along the left-right direction of the vehicle, so that the rear bumper body 1 is fixed to the mounting bracket 2.

[0057] In this optional embodiment, the threaded sleeve 27 can be connected to the vehicle body via fasteners, thereby connecting the vehicle body and the upright plate 26 to each other, and finally fixing the mounting bracket 2 to the vehicle body; in addition, by making the end of the threaded sleeve 27 away from the upright plate 26 closed, when a fastener is screwed into the threaded sleeve 27, the rear end of the fastener will not be exposed, thereby improving the aesthetics.

[0058] Optionally, such as Figure 4 As shown, threaded sleeve 27 can be black, which further enhances its aesthetic appeal. Figure 4 As shown, the rear side of the upright plate 26 can be provided with a recessed groove 262, and the threaded sleeve 27 can be set in the recessed groove 262. This can prevent the threaded sleeve 27 from protruding outward from the rear side of the upright plate 26, thus further improving the aesthetics.

[0059] Optionally, such as Figure 4 As shown, the mounting bracket 2 has a textured surface on the side near the rear bumper body 1.

[0060] Specifically, the texture can be achieved through texture etching treatment.

[0061] In this optional embodiment, by providing a textured surface on the side of the mounting bracket 2 near the rear bumper body 1, the mounting bracket 2 can have a decorative function and improve its aesthetics.

[0062] Optionally, such as Figure 4As shown, since the rear side of the upright plate 26, the upper end face of the first wall portion 211, and the rear side of the second wall portion 212 are exposed in the mounting bracket 2, the texture can be provided only on the rear side of the upright plate 26, the upper end face of the first wall portion 211, and the rear side of the second wall portion 212. This can reduce the processing cost while ensuring the aesthetics.

[0063] This utility model provides a vehicle including the rear bumper mounting structure described above.

[0064] In this embodiment, since the vehicle includes the rear bumper mounting structure as described above, it possesses all the beneficial effects of all embodiments of the aforementioned rear bumper mounting structure, which will not be elaborated upon here.

[0065] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
