[0024] See also Figure 3 and Figure 4 The power-cutting mechanism 3 shown in the figure includes an insulating ring 301 installed on the outside of the positive pole connecting rod 7 and the positive pole connector 8. The ends of the positive pole connecting rod 7 and the positive pole connector 8 that are in contact are both arc-shaped structures. The insulating ring 301 is located between the positive pole connecting rod 7 and the positive pole connector 8. Two symmetrically distributed support plates 302 are fixedly connected to the outside of the insulating ring 301. A mounting plate 303 is fixedly connected between the two support plates 302. Two vertically symmetrical slide plates 304 are fixedly connected to the inside of the box body 1. A sliding hole for limiting the sliding of the slide plate 304 is provided on the surface of the mounting plate 303. The width of the sliding hole is greater than the width of the mounting plate 303. The mounting plate 303 can move along the outside of the slide plate 304. Two symmetrically distributed torsion springs 305 are rotatably installed between the inside of the box body 1 and the mounting plate 303.

[0025] When the electric vehicle receives a strong collision, the impact force causes the box body 1 to pull the torsion spring 305 to bend, and the torsion spring 305 pushes the mounting plate 303 to move along the outer side of the slide plate 304. The mounting plate 303 inserts the insulating ring 301 between the positive pole connecting rod 7 and the positive pole connector 8 through two support plates 302, cutting off the positive pole output of the battery body 2, providing a quick power-off for the electric vehicle, and improving the safety of the battery body 2.

[0027] When the insulating ring 301 is inserted between the positive electrode connecting rod 7 and the positive electrode connector 8, the positive electrode connector 8 can push the pressing plate 401 to move, so that the two sleeves 403 on the pressing plate 401 move along the outer side of the positioning rod 404 and stretch the spring 405.

[0028] Working principle: First, the user connects the motor wiring of the electric vehicle to the positive terminal 8 and the negative terminal 6 respectively, and the battery body 2 can supply power to the electric vehicle. When the electric vehicle receives a strong collision, the impact force causes the box body 1 to pull the torsion spring 305 to bend, and the torsion spring 305 pushes the mounting plate 303 to move along the outside of the slide plate 304. The mounting plate 303 inserts the insulating ring 301 between the positive pole 7 and the positive terminal 8 through two support plates 302. The positive terminal 8 pushes the pressing plate 401 to move, so that the two sleeves 403 on the pressing plate 401 move along the outside of the positioning rod 404 and stretch the spring 405. The insulating ring 301 can be inserted between the positive pole 7 and the positive terminal 8, cutting off the positive output of the battery body 2, and providing a quick power-off for the electric vehicle, thereby achieving the effect of improving the safety of the battery body 2.

The outer sides of the positive terminal 8 and the negative terminal 6 are both provided with annular wiring grooves, which are convenient for installing the power cord of the motor.

[0031] In this embodiment, the user can wrap the power cord of the motor through the installation groove on the box cover 5 and connect it to the annular wiring grooves of the positive terminal 8 and the negative terminal 6, so that the battery body 2 can power the motor and facilitate wiring.

[0032] Embodiment 3
