[0038] Embodiment 1

[0039] Please see attached Figures 1 to 12 The present embodiment provides a bracket 1, which is used to connect the functional module 2 to the carrier 3, and comprises: a bracket body, the bracket body is provided with a plug-in cavity 12 and a plug-in interface 13 connected to the plug-in cavity 12, and the functional module 2 is plugged into the plug-in cavity 12 through the plug-in interface 13; wherein, the bracket body is also provided with at least two welding positioning parts 111, and the bracket 1 is welded to the carrier 3 by the welding positioning parts 111.

[0040] Among them, the above-mentioned functional module 2 includes but is not limited to functional units such as UWB (ultra-wideband antenna) unit, sensor unit, camera unit, communication unit, etc. In this embodiment, the functional module 2 is described as an ultra-wideband antenna unit. The carrier 3 includes a carrier structure to which the above-mentioned functional module 2 may be connected. In this embodiment, the carrier 3 is a bumper of a vehicle body. The functional module 2 includes an outer shell 21, an interface part 22 connected to the outer shell 21, and a control circuit board arranged in the outer shell 21. The bottom edge of the outer shell 21 is provided with a plurality of second limit portions 211, and the outer side of the rear end is provided with a first limit portion 212.

[0041] The welding positioning portion 111 is a groove concavely arranged on the bracket body. Specifically, the welding positioning portion 111 is a groove concavely arranged on the main body of the bracket body. Fig.11 or Fig.12 As shown, the welding positioning portion 111 can be a groove concave downward or a groove concave upward. Correspondingly, when the carrier 3 is processed, the corresponding positioning groove 31 is punched at the preset connection position. When the bracket 1 is connected to the carrier 3, the corresponding welding positioning portion 111 is aligned with the positioning groove 31, and then welding is performed at the welding positioning portion 111 to connect and fix the two. It can be seen that the above-mentioned welding positioning portion 111 has two functions, one is to realize the initial positioning of the welding position of the bracket 1 and the carrier 3, and the other is to form the welding position of the two so that the surface of the welding position will not bulge and affect the overall appearance.

[0042] In this embodiment, the functional module 2 is connected to the carrier 3 by using a bracket 1 with a specific structure. Compared with the existing method of directly welding the functional module 2 to the carrier 3, its positioning is simpler and faster, and the operation difficulty is reduced. At the same time, the use of a bracket 1 structure that can be quickly plugged in significantly improves the assembly efficiency. The worker only needs to slide the functional module 2 from the plug-in interface 13 to the plug-in cavity 12 to achieve reliable assembly of the two.

[0043] At least two welding positioning portions 111 are provided and are arranged close to the edge of the bracket body, so that the positioning is more accurate and welding is more convenient.

[0044] Further, such as Fig. 9 and Fig.10 The bracket body is also provided with a stopper 14, which locks the functional module 2 in the insertion cavity 12 in the opposite direction of its insertion direction. The stopper 14 is an arbitrary structure provided on the bracket body, which can form a force in the opposite direction of the insertion direction, so that the functional module 2 will not be loosened from the insertion cavity 12 after being inserted into the bracket 1.

[0045] Specifically, the stopper 14 is arranged on the inner wall of the plug cavity 12 and close to the plug port 13. The stopper 14 is arranged at a position of the plug cavity 12 close to the plug port 13 to concentrate various structures near the plug cavity 12 for easy integrated molding.

[0046] In this embodiment, the outer shell of the functional module 2 is provided with a first limiting portion 212, and the stop portion 14 is an elastic buckle protruding from the inner cavity wall of the plug-in cavity 12. When the functional module 2 is plugged in by the plug interface 13, the elastic buckle is squeezed and deformed. When the functional module 2 is plugged into the plug-in cavity 12, the elastic buckle is elastically reset and locks the functional module 2. When the functional module 2 is connected to the plug-in cavity 12, the stop portion 14 is elastically reset and just abuts against the first limiting portion 212 of the functional module 2. The elastic buckle is a V-shaped spring sheet structure inclined toward the plug-in cavity 12, and its surface forms an inclined guide surface, so that the functional module 2 can be smoothly plugged into the plug-in cavity 12 from this guide surface. In other embodiments, the elastic buckle can also be a plug-in column combination structure supported by an elastic member, which can be elastically deformed, so that the functional module 2 forms two forms from the plug-in state to the locked state.

[0047] There are at least two elastic buckles, which are arranged on opposite side walls of the plug-in cavity 12. The two elastic buckles act on opposite side walls of the functional module 2 respectively, making the locking more reliable and stable.

[0048] Please refer again Fig.12, the bottom of the plug-in cavity 12 is a hollow structure 121. The hollow structure includes a fully open opening and a mesh structure with a plurality of holes. In this embodiment, the hollow structure 121 is a fully open opening structure. Setting the bottom of the plug-in cavity 12 of the bracket 1 as a fully open opening structure has the following advantages: first, it is convenient for one-piece molding and saves materials; second, the bottom hollowing can facilitate the heat dissipation of the functional module 2; third, it prevents the functional module 2 from being directly hit, reserves a buffer space, and protects the functional module 2.

[0049] Furthermore, a step portion 16 is provided on the side of the side wall of the plug-in cavity 12 close to the hollow structure 121, so that a preset gap is formed at the bottom of the plug-in cavity 12 when the functional module 2 is plugged into the plug-in cavity 12. The step portion 16 can not only limit the functional module 2, but also ensure that a certain gap is reserved at the bottom of the functional module 2. After assembly, the bottom of the functional module 2 will not directly contact the surface of the carrier 3. Correspondingly, a plurality of second limit portions 211 are also provided on the outer shell of the functional module 2, and the second limit portions 211 are hung on the step portion 16 when the two are connected.

[0050] The top of the plug cavity 12 is an open structure, and the open structure is also provided with at least one spanning anti-detachment beam 15. The open top structure with the anti-detachment beam 15 structure can save materials and provide more ventilation and heat dissipation holes to facilitate heat dissipation of the functional module 2. In this embodiment, two anti-detachment beams 15 are provided, and the two anti-detachment beams 15 are arranged roughly parallel to each other.

[0051] A number of reinforcing ribs 171 are further provided on the side wall of the insertion cavity 12 .

[0052] Specifically, in this embodiment, the bracket body includes: a bottom plate portion 11, a side plate portion 17 protruding from the middle of the bottom plate portion 11, the side plate portion 17 enclosing the plug-in cavity 12, and the welding positioning portion 111 is arranged on the bottom plate portion 11. The cavity shape of the plug-in cavity 12 is adapted to the external structure of the functional module 2 to be connected.

[0053] Embodiment 2

[0054] See also Figures 1 to 12 This embodiment provides an ultra-wideband antenna module 10 , which includes a bracket 1 and an ultra-wideband antenna, and the ultra-wideband antenna is connected to the bracket 1 .

[0055] The plug-in port 13 is disposed on a side wall of the plug-in cavity 12 , so that the ultra-wideband antenna and the carrier 3 are slidably engaged in parallel with the plug-in cavity 12 .

[0056] The bracket 1 and its ultra-wideband antenna module 10 of this embodiment are provided with a plurality of welding positioning parts 111 on the bracket body. The bracket 1 can be quickly positioned on the vehicle body through the welding positioning parts 111 and welded and fixed at the corresponding positions. When assembling the UWB unit, it only needs to be inserted into the plug cavity 12 from the plug interface 13 and locked by the stopper 14. The positioning is simple and the operation is convenient, which significantly improves the assembly efficiency.
