[0030] A spring-loaded locking device is applied to a self-locking battery compartment assembly as described above. It includes a push plate 15 slidably connected inside a third rectangular groove 17. Two symmetrically arranged first springs 16 (piano wire SWP-B, k = 2 N / mm) are fixedly connected between one side of the push plate 15 and one inner wall of the third rectangular groove 17. Two symmetrically arranged rectangular holes 10 (0.5 mm chamfered to prevent jamming) are provided at the bottom of the third rectangular groove 17, communicating with the third rectangular groove 17. Two symmetrically arranged sliding grooves 18 are provided at the bottom of the push plate 15, with vertical plates 14 slidingly passing through the inner walls of both sides of the sliding grooves 18. The top of the vertical plates 14 is connected to the sliding grooves. A tension spring 22 is fixedly connected between the top inner walls of the vertical plate 14 and the vertical plate 15. A protruding plate 11 is fixedly connected to one side of the vertical plate 14. The protruding plate 11 engages with the first rectangular groove 6. A clearance groove 24 is provided on the top of the protruding plate 11. The clearance groove 24 engages with the stop block 7. When it is necessary to open the cover plate 2, the two levers 3 can be moved. The two levers 3 drive the two horizontal plates 20 to move closer to each other. At this time, the second spring 19 (spring constant 1.2 N / mm) is compressed. The horizontal plate 20 drives the triangular plate 21 to move laterally. The triangular plate 21 moves vertically downward before the vertical plate 14. The vertical plate 14 drives the protruding plate 11 to move downward and stretch the tension spring 22.
