[0045] Currently, radar systems, as important driver assistance devices, typically require specialized brackets to be mounted to the vehicle body to ensure their stability and accuracy. Meanwhile, bumpers, as a crucial component of the vehicle's appearance, also require independent brackets to ensure a secure connection to the body. However, the separate nature of radar and bumper brackets results in a wide variety of bracket types, potentially reducing overall assembly efficiency.

[0046] To solve this technical problem, this utility model proposes a bumper assembly applied to a vehicle, the vehicle including a body 10.

[0047] Please see Figures 1 to 9In one embodiment of this utility model, the bumper assembly includes an integrated bracket 20 and a bumper 30; the integrated bracket 20 is installed on the vehicle body 10, and the integrated bracket 20 includes an integrally formed radar bracket 21 and a bumper support frame 22, the radar bracket 21 being used to install a radar 40; the bumper 30 is connected to the integrated bracket 20; thereby improving the overall assembly efficiency of the vehicle.

[0048] In the technical solution of this utility model, the radar bracket 21 and the bumper support frame 22 are fixed into a whole by integral molding, and the integrated bracket 20 is installed as a whole onto the vehicle body 10. The radar 40 and the bumper 30 are then installed onto the integrated bracket 20 in sequence. In this way, the integrated bracket 20 has the function of supporting the bumper 30 and installing the radar 40. Compared with the radar bracket 21 and the bumper support frame 22 being independent and interconnected through an additional connecting structure, the integral molding of the radar bracket 21 and the bumper support frame 22 helps to reduce the types and number of brackets, reduce development and maintenance costs, simplify the structure, and improve the overall assembly efficiency and disassembly convenience of the vehicle.

[0049] It should be noted that there are two integrated brackets 20, which are respectively located on the left and right sides of the vehicle body 10 to adaptively support the bumper 30 and improve the structural uniformity and overall balance of the bumper 30. The bumper 30 can be selectively configured as a front bumper or a rear bumper depending on its installation position on the vehicle body 10.

[0050] Optionally, in one embodiment, the radar 40 is a millimeter-wave radar 40. Compared to lidar 40, millimeter-wave radar 40 has stronger anti-interference capabilities in complex environments, meeting all-weather usage requirements and providing reliable environmental perception for the vehicle. Furthermore, millimeter-wave radar 40 achieves a good balance between performance and cost, offering a significant cost-performance advantage compared to other sensors such as lidar 40. Of course, other types of radar 40 can also be mounted on the integrated bracket 20.

[0051] Optionally, in one embodiment, the integrated bracket 20 is a plastic bracket, which is lightweight, low-cost, and easy to manufacture. Specifically, the integrated bracket 20 can be made of PP material to ensure that it has good rigidity and strength, thereby providing good support for the bumper 30.

[0052] Please see Figures 2 to 3 , Figures 5 to 7In this embodiment of the invention, one end of the radar bracket 21 is connected to the bumper support frame 22, and the other end is gradually inclined away from the bumper 30. This allows the integrated bracket 20 to fit the bumper 30 and the vehicle body 10, increasing the contact area, ensuring the fit and connection between the structures, strengthening the bumper 30 and the vehicle body 10, thereby enhancing the vehicle's safety and performance. It also improves the overall structural stability of the integrated bracket 20, thus improving the overall assembly reliability of the vehicle. Of course, in other embodiments, while fitting the vehicle body 10, the radar bracket 21 and the bumper support frame 22 may not be angled; for example, they may be coplanar.

[0053] Please see Figures 2 to 4 In an embodiment of this utility model, the radar bracket 21 is provided with a mounting groove 211 on the side facing the bumper 30, and the radar 40 is snapped into the mounting groove 211. In this way, the radar 40 can be quickly installed into the mounting groove 211 by snapping, which also facilitates the quick disassembly of the radar 40, thereby helping to improve the overall disassembly and assembly efficiency.

[0054] When the radar 40 is mounted in the mounting slot 211, since the mounting slot 211 is located on the side of the radar bracket 21 facing the bumper 30, the radar 40 can be positioned between the bumper 30 and the integrated bracket 20. Furthermore, the mounting slot 211 provides protection for the radar 40 without affecting its normal operation, thereby improving its safety and reliability. Simultaneously, it reduces the size of the radar 40 protruding from the integrated bracket 20, achieving a compact connection between the integrated bracket 20 and the radar 40, which helps to reduce the overall space occupied by the integrated bracket 20 and the radar 40, thus improving the miniaturization level of the vehicle body 10, the integrated bracket 20, the radar 40, and the bumper 30. Of course, in other embodiments, the mounting slot 211 is located on the side of the radar bracket 21 facing the vehicle body 10.

[0055] Please see Figure 4 In this embodiment of the invention, the radar 40 is at least partially disposed in the mounting groove 211; that is, a portion of the radar bracket 21 is allowed to protrude from the opening of the mounting groove 211, providing a position for applying force, thereby improving the ease of disassembly and assembly of the radar 40 to a certain extent, facilitating the quick disassembly and installation of the radar 40. Of course, in other embodiments, the radar 40 is entirely built into the mounting groove 211.

[0056] Optionally, in an embodiment of this utility model, the mounting groove 211 has a mounting buckle 212 along its groove edge, and the radar 40 has a latching protrusion 41 that cooperates with the mounting buckle 212 on its side wall. It is understood that when the mounting groove 211 has a lateral opening away from the bumper support frame 22, such as... Figure 8 and Figure 9 As shown, a groove is formed between the mounting buckle 212 and the groove opening of the mounting slot 211. Both the openings of the groove and the mounting slot 211 are located away from the bumper support frame 22. When the radar 40 is installed onto the radar bracket 21, the radar 40 enters the mounting slot 211 laterally through the opening. Guided by the groove wall of the mounting slot 211, the radar 40 moves closer to the connection point between the radar bracket 21 and the bumper support frame 22. During this process, the locking protrusion 41 can enter the groove through the opening of the groove, such as... Figure 5 and Figure 8 As shown, the radar 40 and the radar bracket 21 are connected by a snap-fit ​​mechanism.

[0057] The radar 40 has locking protrusions 41 on both opposite side walls, with multiple protrusions spaced apart on each side. This increases the limiting points between the radar 40 and the radar bracket 21, improving the connection strength between them. The radar 40 can be vertically installed into the mounting groove 211 first, and then the locking protrusions 41 can slide laterally into the grooves formed by the mounting buckles 212, thus securing the radar 40. The locking protrusions 41 can be located away from the bottom of the mounting groove 211, specifically in the middle or top of the side wall. In other embodiments, the radar 40 and radar bracket 21 can also be connected by screws 50, snap-fit ​​installation, or plug-in connection. In other embodiments, the mounting groove 211 may not have a lateral opening; or the radar 40 may enter the mounting groove 211 vertically through its opening, and during entry, the mounting buckles 212 engage with the locking protrusions 41. In this case, the locking protrusions 41 may have a locking hole structure for the mounting buckles 212 to insert into.

[0058] Please see Figure 8 and Figure 9 In this embodiment of the present invention, an elastic piece 213 is provided on the side wall of the mounting groove 211 near the bumper support frame 22. The elastic piece 213 is used to elastically abut against the radar 40. In this way, through the elastic holding force of the elastic piece 213, combined with the snap-fit ​​setting of the mounting buckle 212 and the snap-fit ​​protrusion 41, the stable assembly of the radar 40 on the integrated bracket 20 can be ensured, the possibility of the radar 40 shaking in the mounting groove 211 can be reduced, thereby improving the installation stability of the radar 40. It can also make the radar bracket 21 adaptable to radars of different sizes or types, improving the compatibility of the integrated bracket 20.

[0059] The elastic sheet 213 is manufactured using a continuous bending process, which improves its structural strength and ensures that its elastic holding force can act on the radar 40. Furthermore, the elastic sheet 213 includes an elastic connecting section and an elastic holding section. The elastic holding section is connected to the radar bracket 21 via the elastic connecting section, and it can be adapted to the side wall of the radar 40 so that it fits snugly against the radar 40, increasing the effective contact area between the radar 40 and the elastic sheet 213 and improving the holding effect of the elastic sheet 213.

[0060] Optionally, in an embodiment of this utility model, the bottom of the mounting groove 211 is provided with a clearance hole 214 to avoid the elastic sheet 213; this provides space for the elastic sheet 213 to deform elastically, improving the deformation reliability of the elastic sheet 213. The clearance hole 214 can be a through hole or a blind hole.

[0061] Optionally, in an embodiment of the present invention, the bottom of the mounting groove 211 is provided with a first clearance groove 215 to avoid the radar 40, which can reduce the effective contact area between the radar 40 and the bottom wall of the mounting groove 211, and help improve the smoothness of the radar 40's movement on the integrated bracket 20.

[0062] In addition, when the clearance hole 214 is a through hole, the clearance hole 214 can extend to the first clearance groove 215, which makes it convenient for other components to extend out of the first clearance groove 215.

[0063] Optionally, in an embodiment of the present invention, the bottom of the mounting groove 211 is provided with a second clearance groove 216, and the edge of the groove opening of the second clearance groove 216 contacts the bottom wall of the radar 40. In this way, the radar 40 is reliably supported, and the effective contact area between the radar 40 and the bottom wall of the mounting groove 211 is reduced, which helps to improve the smoothness of the movement of the radar 40 on the integrated bracket 20.

[0064] like Figure 6 As shown, the bottom of the mounting groove 211 is also provided with a first clearance groove 215 to avoid the radar 40, and two sets of second clearance grooves 216 are provided, which are respectively located on opposite sides of the first clearance groove 215. This helps to further reduce the effective contact area between the radar 40 and the bottom wall of the mounting groove 211, and further improve the smoothness of the movement of the radar 40 on the integrated bracket 20.

[0065] Please see Figures 6 to 9In an embodiment of this utility model, the integrated bracket 20 is provided with a reinforcing rib 23 extending toward the bumper 30 along its upper edge. The reinforcing rib 23 extends from the bumper support frame 22 to the radar bracket 21, thereby helping to improve the connection strength and connection stability of the radar bracket 21 and the bumper support frame 22, thus ensuring the supporting and connecting function of the integrated bracket 20 for the bumper 30.

[0066] See also Figure 2 In this embodiment of the present invention, the upper edge of the integrated bracket 20 is adapted to the upper edge of the bumper 30; the engagement and positioning of the auxiliary buckle 242 facilitates the connection between the integrated bracket 20 and the bumper 30.

[0067] The upper edge of the integrated bracket 20 and the upper edge of the bumper 30 are engaged through a locking structure 241 and a fastener 242. The locking structure 241 can be a locking hole or a locking protrusion on the bumper 30 or the integrated bracket 20. The fastener 242 is located on the integrated bracket 20 or the bumper 30. Therefore, after the integrated bracket 20 is installed on the vehicle body 10, the bumper 30 can be assembled onto the integrated bracket 20 through the engagement of the locking structure 241 and the fastener 242. Of course, in other embodiments, the bumper 30 and the integrated bracket 20 can also be connected by screws, plug-in connections, or other methods.

[0068] Please see Figures 6 to 7 In an embodiment of this utility model, the bumper support frame 22 has a first mounting surface 221 and a second mounting surface 222 that are smoothly connected. Both the first mounting surface 221 and the second mounting surface 222 are provided with mounting positions 223 that are connected to the vehicle body 10, thereby realizing the connection between the bumper support frame 22 and the vehicle body 10.

[0069] Depending on the shape of the vehicle body 10, the first mounting surface 221 and the second mounting surface 222 can be coplanar or staggered, connecting to form a smoothly transitioning stepped structure. This provides better positioning and support, effectively disperses stress at the connection point, reduces the risk of tearing caused by stress concentration, and improves the overall strength and durability of the structure.

[0070] When the integrated bracket 20 is connected to the vehicle body 10 by screws 50, the radar bracket 21 is provided with a screw-in position 217 for connection to the vehicle body 10; and / or, the bumper support bracket 22 is connected to the vehicle body 10 by screws 50, that is, a nut 51 can be pre-installed on the mounting position 223 to be configured as the screw-in position 217; the design of the relative position between the first mounting surface 221 and the second mounting surface 222 can ensure the stability and reliability of the bolt connection. In addition, the detachability of the bolt connection also makes the installation and maintenance of the integrated bracket 20 more convenient.

[0071] Furthermore, in embodiments of this utility model, the number of mounting positions 223 on the first mounting surface 221 and the second mounting surface 222 may be different, such as... Figure 6 As shown, since the area of ​​the first mounting surface 221 is larger than that of the second mounting surface 222, it can withstand greater force. By setting two mounting positions 223 on the first mounting surface 221, the stress can be distributed more evenly, reducing the risk of excessive force at a single point and enhancing the reliability of the connection. At the same time, the two mounting positions 223 can make the first mounting surface 221 fit more firmly against the vehicle body 10, avoiding shaking or twisting due to force at a single point. In addition, if one mounting position 223 becomes loose or damaged, the other can provide redundant protection.

[0072] The second mounting surface 222 is subjected to relatively less force, and a single screw connection 217 is sufficient for support. In this way, the mechanical performance requirements are met, while also taking into account the convenience of assembly or cost.

[0073] This utility model also proposes a vehicle that includes a bumper assembly. The specific structure of the bumper assembly is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
