[0035] The loading and unloading mechanism includes: a connection box 5 fixedly installed at the bottom of the box 2, a plug rod 7 installed through the battery box body 1 and the side wall of the connection box 5, a linkage component that drives the plug rod 7 to move, and a positioning component for positioning the box 2 when it is installed; the linkage component includes: a rotating rod rotatably installed on the side wall of the box 2 and the connection box 5, a rotating plate 3 fixedly installed on the top of the rotating rod, a disc 4 fixedly sleeved on the outer edge of the rotating rod, a guide groove provided on the side wall of the disc 4, a linkage rod 6 installed through the inner cavity of the guide groove, a fixing ring 8 fixedly sleeved on the outer edge of the plug rod 7, and a linkage spring 9 sleeved on the outer edge of the plug rod 7; one end of the plug rod 7 is fixedly installed on the outer edge of the linkage rod 6, one end of the linkage spring 9 is fixedly installed on the inner wall of the connection box 5, and the other end is fixedly installed on one side of the fixing ring 8;

[0036] By rotating the rotating plate 3, the rotating rod is driven to rotate through the rotating plate 3, and the disc 4 is driven to rotate through the rotating rod, and the linkage rod 6 is driven to move through the guide groove on the disc 4. Since the guide groove is in an arc shape and moves from the edge of the disc 4 to the center of the disc 4, the linkage rod 6 can be driven to move closer to or away from the center of the disc 4 under the action of the guide groove.

[0037] There are four groups of guide grooves, which are evenly distributed in a ring shape on the side wall of the disc 4. The four groups of guide grooves control the movement of the four groups of linkage rods 6, and then control the movement of the four groups of plug-in rods 7. The four groups of plug-in rods 7 correspond to the four side walls of the battery box body 1 respectively. When the four groups of plug-in rods 7 are respectively plugged into the side walls of the adjacent battery box body 1, the box 2 can be stably fixed on the top of the battery box body 1, avoiding the box 2 from falling off from the top of the battery box body 1, and improving the firmness of the connection between the battery box body 1 and the box 2;

[0039] When the box 2 needs to be installed on the top of the battery box body 1, after the box 2 is attached to the top of the battery box body 1, the rotating plate 3 is loosened. At this time, the elastic force of the linkage spring 9 can drive the fixing ring 8 to reset, and the fixing ring 8 drives the plugging rod 7 away from the center of the disc 4, so that the plugging rod 7 is plugged into the inner wall of the battery box body 1 again, so that the box 2 can be easily fixed on the top of the battery box body 1;

[0042] When installing the box 2, the positioning plates 10 at the bottom of the box 2 are respectively inserted into the adjacent positioning groove cavities, thereby playing a positioning role when installing the box 2, so that the box 2 and the battery box body 1 are quickly aligned, avoiding displacement during installation of the box 2, and improving the installation efficiency of the battery box body 1 and the box 2. At the same time, when the battery box body 1 and the box 2 are positioned, the four groups of plug-in rods 7 are respectively inserted into the inner wall of the battery box body 1 and inserted into the adjacent positioning hole cavities. Through the mutual cooperation of the plug-in rods 7 and the positioning plates 10, the box 2 can be locked on the top of the battery box body 1, further improving the firmness of the fixation of the battery box body 1 and the box 2.
