The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0030] Nowadays, vehicles widely use battery packs as one of their power sources. In the process of assembling the battery pack to the vehicle body, it is necessary to assemble the welded battery pack by superimposing the gasket on the embedded block of the battery pack mounting bracket. The prior art generally adopts a threaded connection, that is, inserting part of the gasket into the embedded nut so that the threaded parts of the gasket and the embedded nut contact each other to form a connection. However, this will reduce the wall thickness of the embedded nut, and the embedded nut becomes a weak point in the bolt fastening structure. In addition, the processing cost of the threaded parts of the embedded nut and the gasket is relatively high.

[0031] The present application proposes an assembly component, a battery pack and a vehicle. Compared with the prior art, the inlay block and the pad block of the assembly component have a simple structure, small processing volume, low cost, and ensure that the inlay block has sufficient wall thickness and good strength. The assembly component of the present application can ensure that the battery pack is stably assembled on the vehicle.

Figure 1 , the assembly component 1 may include a cushion block 2, an inlay block 3, a covering member 4 and a connector 5. The assembly component 1 may be used to connect a battery pack and a vehicle body. The cushion block 2 may be cylindrical, and the cushion block 2 may include a first contact surface 21, and the cushion block 2 may have a first channel 22, and the first channel 22 may pass through the cushion block 2. The inlay block 3 may be cylindrical, and the inlay block 3 may include an outer side wall 31 and a second contact surface 32, and the inlay block 3 may have a second channel 33, and the outer side wall 31 may be arranged along the circumference of the inlay block 3, and the second contact surface 32 may abut against the first contact surface 21, and the second channel 33 may pass through the inlay block, and the first channel 22 may be connected with the second channel 33 along the first direction. The covering member 4 may be located on the cushion block 2 and may be connected to the outer side wall 31 to fix the cushion block 2 and the inlay block 3. The connector 5 may be used to pass through the battery pack, the second channel 33, the first channel 22 and the vehicle body to connect the battery pack and the vehicle body.

[0033] In a possible implementation, the covering member 4 may be an annular structure, and the covering member 4 is convexly disposed on the first contact surface 21 along the axial direction of the cushion block 2, and the covering member 4 may be in contact with the outer side wall 31. Figure 1In the assembly component 1, the first contact surface 21 of the cylindrical pad 2 can be abutted against the second contact surface 32 of the cylindrical mosaic block 3. At this time, the first channel 22 of the cylindrical pad 2 can be connected with the second channel 33 of the cylindrical mosaic block 3 along the first direction. Schematically, the first direction can be the axial direction of the cylindrical pad 2 and the cylindrical mosaic block 3. The first contact surface 21 and the second contact surface 32 can both be circular, and the diameter length of the first contact surface 21 can be greater than the diameter length of the second contact surface 32. On this basis, the annular covering member 4 can be protruded on the first contact surface 21 along the axial direction of the cylindrical pad 2, and the annular covering member 4 can contact the outer wall 31. Therefore, the embodiment of the present application can avoid using the threaded structure in the prior art to generate the connection strength between the pad 2 and the mosaic block 3, thereby simplifying the structure of the assembly component 1. While the mosaic block 3 has sufficient wall thickness and good strength, the connection strength between the pad 2 and the mosaic block 3 can be guaranteed.

On this basis, at least two covering members 4 can be spaced apart along the circumferential direction on the outer wall 31 of the cushion block 2, and there can be a gap between at least two covering members 4. The gap cooperates with the opening 41 of the covering member 4 itself to facilitate deformation of the covering member 4 under the clamping pressure of the tool, so that the covering member 4 can be at least partially located in the first groove 34 and can abut against the inner wall of the first groove 34, so that the mosaic block 3 can have sufficient wall thickness and good strength while effectively increasing the connection strength between the cushion block 2 and the mosaic block 3.

While the mosaic block 3 has sufficient wall thickness and good strength, the connection strength between the cushion block 2 and the mosaic block 3 can be guaranteed.

[0039] In a possible implementation, the covering member 4 may be in contact with both the cushion block 2 and the inlay block 3 .
