The mounting component 102 is welded to the lower skirt plate 101, and then the buckle seat 103 is snapped onto the mounting component 102. Subsequently, the lower chuck 105 is operated so that the snap-fit ​​post 106 passes through the guide groove. Guided by 108, the clip is inserted into the buckle seat 103, and then the upper expansion clip 107 is assembled. The limiting spring 104 restricts the positions of the clip post 106, the lower chuck 105, and the upper expansion clip 107, ensuring they are always in the correct positions. If the battery pack frame hole shifts to the left during installation, the upper expansion clip 107 will push the limiting spring 104 to undergo elastic deformation, eliminating misalignment caused by the installation hole offset tolerance. This achieves effective connection under allowable tolerance offset conditions. By adding a spring structure in the double-layer clip mounting groove, the double-layer clip is limited to the correct position and can also avoid external force, ensuring that the two parts can be accurately and smoothly installed even with dimensional deviations.

[0022] Secondly, the welding frame 109 is fixedly connected to the lower skirt plate 101 and is located on one side of the lower skirt plate 101; a plurality of the buckle brackets 110 are fixedly connected to the welding frame 109 respectively and are located on one side of the welded part.

[0024] In addition, the expansion sleeve 112 is fixedly connected to the snap-fit ​​post 106 and is located on one side of the snap-fit ​​post 106; the upper chuck 113 is fixedly connected to the expansion sleeve 112 and is located on one side of the expansion sleeve 112. The expansion sleeve 112 is used to cooperate with the upper chuck 113 to snap the battery pack frame.

[0025] Furthermore, the expansion cylinder 114 is fixedly connected to the snap-fit ​​post 106 and is located on one side of the snap-fit ​​post 106; the two expansion buckles 115 are fixedly connected to the expansion cylinder 114 respectively and are located on both sides of the expansion cylinder 114. The expansion cylinder 114 cooperates with the expansion buckles 115 to expand and snap into the mounting holes of the battery pack frame, thereby completing the assembly of the lower skirt plate 101.

[0026] When using this utility model, the welding frame 109 is welded to the lower skirt plate 101, and then the buckle seat 103 is snapped into the welding frame 109 by snapping into the buckle slot 111 and the buckle bracket 110. Then, the lower chuck 105 is operated so that the buckle post 106, guided by the guide slot 108, is inserted into the buckle seat 103. The assembly of the upper expansion buckle 107 is then completed. The limiting spring 104 restricts the buckle post 106, the lower chuck 105, and the... The upper expansion clip 107 is positioned so that it is always in the correct position. If the battery pack frame hole shifts to the left during installation, the upper expansion clip 107 will push the limiting spring 104 to undergo elastic deformation, eliminating the misalignment caused by the offset tolerance of the mounting hole. This achieves effective connection under the condition of allowable tolerance deviation. By adding a spring structure in the double-layer buckle mounting groove, the double-layer buckle is limited to the correct position and can also avoid the action of external force, ensuring that the two parts can be accurately and smoothly installed even with dimensional deviations.
