[0031] 3. This invention is composed of a dustproof net 21, a first bevel gear 16, a second bevel gear 28, a screw rod 29, a guide rod 31 and other components. This structure can ensure that dust and impurities will not enter the interior of the device, thereby increasing the service life of the battery.

[0032] 4. In summary, this device can increase the service life of the battery, has strong shock and drop resistance, improves the safety performance of the electric vehicle power source, increases the service life of the electric vehicle, and improves the cost performance of the electric vehicle.

[0033] Working principle: when external force touches the electric vehicle, it drives the movable plate 6 to move, and the movable plate 6 drives the sliding rod 12 to move, and the movable plate 6 causes the rubber block 13 to deform. Due to the action of the rubber block 13, part of the impact force is reduced, and the sliding rod 12 drives the third spring 10 to be in a compressed state. The sliding rod 12 drives the rotating rod 8 to move, and the rotating rod 8 moves the first spring 7 to be in a compressed state. Under the joint action of the rubber block 13, the first spring 7, and the third spring 10, the external punching force is reduced by more than half, protecting the safety of the battery 3. The second inclined plate 17 is fixed to the surface of the first inclined plate 15 by bolts passing through the second through hole, the third through hole and the fourth through hole. Due to the presence of the water trough 23, when rainwater enters the inside of the device body 1, it will flow out of the device body 1 from the water trough 23, so that the battery 23 is not eroded by rainwater, and the second fixed plate 16 is pulled. The second fixed plate 16 drives one end to pass through the fifth fixed plate 34 opposite to the second fixed plate 16, and the knob 24 is rotated. The knob 24 drives the first bevel gear 26 to rotate, and the first bevel gear 26 drives the second bevel gear 28 to rotate. The second bevel gear 28 drives the screw 32 to rotate, and the screw 32 drives the screw 29 to move downward. When one end of the screw 29 passes through the through hole on one side of the second fixed plate 16, the dustproof net is fixed directly above the battery 23 to block the dust.
