[0132] It can be seen from the above technical solution that the utility model has at least the following advantages and positive effects:

[0133] In the present application, the battery pack can be effectively fixed on the support frame through the cooperation between the first connecting plate and the second connecting plate of the connecting member, the locking member and the through holes on the edge of the battery pack, thereby preventing the battery pack from being displaced during movement and more effectively ensuring the safety and stability of the battery pack.

[0134] Further, the mounting plate is vertically connected to the first connecting plate and is located above the first connecting plate, and a mounting hole is provided on the mounting plate. The transition plate is vertically connected to the second connecting plate and is located above the second connecting plate, and a through hole is provided on the transition plate. The fastener is inserted into the mounting hole and the through hole to realize the connection between the first connecting plate and the second connecting plate.

[0135] Furthermore, the stop plate of the stop member cooperates with the limiting plate of the connector to limit the displacement of the battery pack along the second direction, which can effectively prevent the battery pack from being damaged due to vibration and impact during movement to ensure the safety of the battery pack.

[0136] The abutment plates of the two stoppers cooperate with each other to limit the displacement of the battery pack along the first direction, and can effectively prevent the battery pack from being damaged due to vibration and impact during movement, so as to ensure the safety of the battery pack.

[0137] Furthermore, the connection end of the pressing member is rotatably connected to the support frame so that the free end can move upward away from the connection member, or move downward toward the connection member and connect with the connection member, thereby pressing the battery pack against the support frame. This design can press and fix the edge of the battery pack against the support frame, and by connecting the pressing member to the connection member, the degree of pressing on the battery pack is increased, which can effectively prevent the battery pack from being damaged due to vibration and impact during movement, thereby ensuring the safety of the battery pack.

[0138] Furthermore, one end of the reinforcement piece along the first direction is connected and fixed to the outer side of the open end of the frame body, and the other end extends inward to abut against the top of the clamping piece, so as to strengthen the clamping effect of the clamping piece on the battery pack, so that the clamping piece can better limit the battery pack.
