[0045] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0047] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0048] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] This embodiment provides a bracket assembly for installing a radar, which can simplify the installation steps and reduce the entry of dust or water into the interior of the vehicle frame through the opening of the vehicle body trim 400. Figure 1 and Figure 2 As shown, the bracket assembly includes a first bracket 11 and a second bracket 12. The first bracket 11 is fixedly connected to the vehicle body trim 400, and the first bracket 11 is a double-layer structure; the second bracket 12 is detachably connected to the lower layer of the first bracket 11, one end of the second bracket 12 is attached to the vehicle body trim 400 and forms a accommodating space 121 with the vehicle body trim 400, the vehicle body trim 400 is provided with a wire hole 410 facing the accommodating space 121, and the radar 20 is connected to the side of the second bracket 12 facing away from the first bracket 11. The above-mentioned bracket assembly is achieved by fixing the first bracket 11 to the body trim panel 400 so that the first bracket 11 and the body trim panel 400 are integrated during the manufacturing stage of the body trim panel 400, thereby eliminating the tedious assembly steps of the first bracket 11 and the body trim panel 400. At the same time, the second bracket 12 is provided with the accommodating space 121 so that the accommodating space 121 covers the wire hole 410, and the wire hole 410 is no longer exposed to the outside, thereby preventing dust or water from entering the body trim panel 400 through the wire hole 410, thereby ensuring the smooth operation of the internal parts of the body trim panel 400. Furthermore, the detachable setting of the second bracket 12 and the first bracket 11 makes it possible to first install the radar 20 and the second bracket 12 on the outside, and then install the second bracket 12 on the first bracket 11, which is convenient for installation. If the radar 20 needs to be disassembled, the second bracket 12 can be removed from the first bracket 11, thereby achieving the effect of convenient disassembly and assembly.

[0050] It can be understood that the radar 20 is connected to the connecting wire 30 to transmit signals or make electrical connections, and the connecting wire 30 is arranged through the wire hole 410.

[0051] In addition, the double-layer structure of the first bracket 11 improves the structural strength of the first bracket 11 on the one hand, and facilitates the installation of the second bracket 12 on the other hand.

[0052] Optionally, the first bracket 11 is connected to the body trim panel 400 by welding, and the first bracket 11 and the body trim panel 400 are both made of sheet metal. Since the body trim panel 400 and the first bracket 11 are made of the same material, and since welding is also required in the process of making the body trim panel 400, during the process of making the body trim panel 400, the operator can weld the first bracket 11 at the same time. Moreover, compared with the plastic material in the prior art, the sheet metal material has low cost and is easy to obtain.

[0053] In other embodiments, the vehicle body trim panel 400 and the first bracket 11 may also be integrally formed, which is not limited here.

[0054] Specifically, if Figure 3 As shown, the first bracket 11 includes an upper plate 111, a first reinforced vertical wall 112 and a lower plate 113, wherein a portion of the edge of the upper plate 111 is welded to the periphery of the vehicle body trim 400; the first reinforced vertical wall 112 is formed by extending downward from another portion of the edge of the upper plate 111, and both ends of the first reinforced vertical wall 112 are welded to the vehicle body trim 400; the lower plate 113 is connected to one end of the first reinforced vertical wall 112 away from the upper plate 111, and the second bracket 12 is detachably connected to the lower plate 113. It can be understood that the upper plate 111 and the first reinforced vertical wall 112 are both welded to the vehicle body trim 400, and there are enough welding positions to improve the stability of the connection between the first bracket 11 and the vehicle body trim 400.

[0055] Alternatively, if Figure 3 As shown, the first bracket 11 further includes a reinforcement member 114, the two ends of which are respectively connected to the vehicle body trim panel 400 and the first reinforcement vertical wall 112, and the top of the reinforcement member 114 is connected to the upper plate 111. Through the above arrangement, on the one hand, the reinforcement member 114 supports the large surface of the relatively flat upper plate 111 to prevent deformation, and on the other hand, further increases the welding area between the first bracket 11 and the vehicle body trim panel 400, thereby improving the connection stability between the two.

[0056] Furthermore, in another embodiment, in order to further increase the support strength of the upper plate 111, Figure 3 A reinforcing beam is additionally provided on the basis of the reinforcing member 114, and the reinforcing beam is cross-arranged with the reinforcing member 114.

[0057] Alternatively, if Figure 4As shown, the position where the radar 20 is installed on the second bracket 12 is the connecting plate 122. The radar 20 includes a connected mounting seat 21 and a transmitter 22. A threaded hole is provided on the side of the mounting seat 21 away from the transmitter 22. The second locking member 14 passes through the connecting plate 122 and is threadedly connected to the threaded hole to fix the mounting seat 21 on the connecting plate 122. At this time, the second locking member 14 protrudes from the connecting plate 122, which will affect the close setting of the connecting plate 122 and the first bracket 11.

[0058] In order to solve the above problems, combined Figure 3 and Figure 4 The lower plate 113 includes a first plate 1131 and a second plate 1132. The first plate 1131 is connected to the end of the first reinforcing wall 112 away from the vehicle body trim 400; the second plate 1132 is spaced apart from the first plate 1131 and connected to the first reinforcing wall 112 to avoid the installation position of the radar 20 on the second bracket 12. It can be understood that the installation position of the radar 20 on the second bracket 12 is the protruding position of the second locking member 14. The above arrangement can not only realize the connection between the lower plate 113 and the connecting plate 122, but also ensure the close connection between the lower plate 113 and the connecting plate 122, and the connection is more stable.

[0059] Alternatively, if Figure 6 As shown, at least three connecting members 1133 are protruding from the lower plate 113 toward the second bracket 12. In this embodiment, two connecting members 1133 are provided on the first plate 1131, and one connecting member 1133 is provided on the second plate 1132. In other embodiments, if space permits, the number of connecting members 1133 can be appropriately increased, which is not limited here.

[0060] In this embodiment, see Figure 5 and Figure 6 The connecting member 1133 is a stud, which passes through the through hole 1222 opened on the connecting plate 122. The first locking member 13 is connected to the free end of the connecting member 1133 and presses the second bracket 12 against the first bracket 11. The first locking member 13 is a nut. In other embodiments, the connecting member 1133 can also be a column with a slot, and the first locking member 13 is a buckle, which is not limited here.

[0061] Optionally, a side of the second bracket 12 facing the first bracket 11 is provided with an oblong hole 1221 corresponding to each connecting member 1133, and the connecting member 1133 is provided through the oblong hole 1221. Through the above arrangement, compared with the round hole, the oblong hole 1221 makes the insertion tolerance of the connecting member 1133 larger when the connecting plate 122 is buckled onto the first bracket 11, making it easier to install the connecting plate 122 and reducing the difficulty of assembly.

[0062] Alternatively, see Figure 5 and Figure 6The second bracket 12 has a double-layer structure. The bracket assembly 10 further includes a cover plate 16. The cover plate 16 is connected to the lower layer of the second bracket 12 to cover the accommodating space 121. The mounting seat 21 is installed on the upper layer of the second bracket 12 away from the first bracket 11 and is located in the accommodating space 121. The emitting element 22 is connected to the mounting seat 21 and protrudes from the cover plate 16. The cover plate 16 is provided with an avoidance hole 161 for avoiding the emitting element 22. The double-layer structure of the second bracket 12 ensures the structural strength of the second bracket 12. At the same time, the setting of the cover plate 16 makes the accommodating space 121 relatively closed except for the avoidance hole 161, further improving the dustproof and waterproof effect of the bracket assembly 10.

[0063] Alternatively, if Figure 5 and Figure 6 As shown, the second bracket 12 also includes a second reinforcing wall 124 and a connecting flange 123. The second reinforcing wall 124 is formed by a portion of the connecting plate 122 extending downward. The connecting flange 123 is parallel to the connecting plate 122 and connected to the second reinforcing wall 124. The covering plate 16 is connected to the connecting flange 123. The second reinforcing wall 124 can not only improve the strength of the second bracket 12, but also form a accommodating space 121 of a certain height.

[0064] In this embodiment, two connecting flanges 123 are provided, and the two connecting flanges 123 are at both ends of the length direction of the second bracket 12. In other implementations, more connecting flanges 123 can be provided, which is not limited here. It should be noted that the setting position of the connecting flange 123 needs to avoid the radar 20.

[0065] In order to realize the connection between the connecting flange 123 and the cover plate 16, as shown in FIG. Figure 5 and Figure 6 As shown, a connecting nut 1231 is fixedly connected to the side of the connecting flange 123 facing away from the covering plate 16 , and the third locking member 15 is threadedly connected to the connecting nut 1231 and abuts against the covering plate 16 to connect the third connecting member 1133 to the second bracket 12 .

[0066] In other embodiments, the connection method between the second bracket 12 and the cover plate 16 may also be set with reference to the connection method between the first bracket 11 and the second bracket 12 , which will not be described in detail herein.

[0067] Optionally, the emitting element 22 is hemispherical, so that the emitting element 22 can emit both downward and circumferentially, thereby increasing the sensing range of the emitting element 22 .

[0068] Optionally, the second bracket 12 and the cover plate 16 are also sheet metal parts, that is, the entire bracket assembly 10 is a sheet metal part, which is easy to obtain, saves costs, and is easy to ensure structural strength.

[0069] Optionally, the positions where the second bracket 12 and the cover plate 16 are attached to the body trim 400 are coated with sealant, which can further improve the sealing between the entire bracket assembly 10 and the body trim 400, better prevent dust and the like from entering the interior of the bracket assembly 10, and further prevent dust and other debris from entering the interior of the body trim 400.

[0070] This embodiment also provides an unmanned vehicle, which includes a vehicle body trim panel 400 and the bracket assembly, wherein the first bracket 11 is fixedly connected to the vehicle body trim panel 400. By adopting the bracket assembly, the unmanned vehicle has fewer installation steps, and water or dust is not easily entered into the interior of the unmanned vehicle, thereby reducing the probability of internal failure.

[0071] It should be noted that the unmanned vehicle can be any automated vehicle such as a cleaning vehicle, a logistics vehicle, an express delivery vehicle, etc., and is not limited here.

[0072] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
