[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] As Figure 1 and Figure 4 shown, a protection structure includes a battery protection box 1, a fixed frame 2 arranged on the left side of the battery protection box 1, a battery body 3 and a clamping and installation mechanism 4 arranged inside the battery protection box 1.

A filter screen plate 503 is arranged on the right side of the heat dissipation fan 502. Chutes 504 are opened on both sides of the inner wall of the fan frame 501. The external gas can be filtered by the filter screen plate 503 and introduced into the interior of the battery protection box 1 through the heat dissipation fan 502, and discharged through a plurality of air holes 6, so that the gas circulates inside the battery protection box 1, which can be used to provide heat dissipation treatment for the battery body 3.

[0030] As Figure 1 and Figure 4As shown, a movable pressure rod 505 is provided on the right side of the filter screen plate 503. Both ends of the movable pressure rod 505 are connected with locking screws 508. One end of the locking screw 508 extending into the interior of the movable pressure rod 505 is connected with a "T"-shaped shaft. Grooves 507 are formed on both sides of the filter screen plate 503. Inside the grooves 507, there are inserted blocks 506. The inserted blocks 506 are adapted to the grooves 507. The two sides of the filter screen plate 503 and the movable pressure rod 505 can be correspondingly inserted into the interior of the sliding groove 504, and the movable pressure rod 505 can be pressed against the filter screen plate 503. By rotating the locking screw 508, the movable pressure rod 505 is pushed to move, so that the inserted blocks 506 at both ends of the movable pressure rod 505 are correspondingly inserted into the grooves 507 on both sides of the filter screen plate 503, thereby restricting the position of the filter screen plate 503. By rotating the locking screw 508 in the reverse direction, the inserted block 506 can be separated from the groove 507, and the filter screen plate 503 can be pulled out through the interior of the fan frame 501, thus improving the convenience of disassembling and assembling the filter screen plate 503.

[0031] As Figure 1 , Figure 2 and Figure 3As shown, the clamping and mounting mechanism 4 includes movable push plates 401 and clamping plates 402 located on both sides of the battery body 3. The movable push plate 401 is connected with a fixed column 406. Inside the fixed column 406 is connected a lead screw sleeve 407. Inside the lead screw sleeve 407 is inserted a support lead screw 408. The input end of the support lead screw 408 is connected with a coaxial worm gear 409. At the rear end of the coaxial worm gear 409 is arranged a horizontal worm 410. The input end of the lower horizontal worm 410 is connected with a servo motor 414. Inside the fixed frame 2 is arranged a transmission shaft 413. Both ends of the transmission shaft 413 are connected with transmission bevel gears 412. On one side of the transmission bevel gear 412 is arranged a fixed bevel gear 411. The transmission shaft 413 is fixedly connected with the transmission bevel gear 412. The transmission bevel gear 412 meshes with the fixed bevel gear 411. The fixed bevel gear 411 is fixedly connected with the horizontal worm 410. The horizontal worm 410 meshes with the coaxial worm gear 409. The coaxial worm gear 409 is fixedly connected with the support lead screw 408. The support lead screw 408 passes through the inside of the lead screw sleeve 407. The lead screw sleeve 407, the fixed column 406 and the movable push plate 401 are fixedly connected. The servo motor 414 can drive the coaxial worm gear 409 and the support lead screw 408 to rotate synchronously through the horizontal worm 410. The support lead screw 408 can push the lead screw sleeve 407 and the fixed column 406 to move synchronously. Since the fixed column 406 is fixedly connected with the movable push plate 401, it can push the movable push plate 401 to move. The lower horizontal worm 410 can drive the transmission shaft 413 to rotate through the fixed bevel gear 411 and the transmission bevel gear 412 at the bottom. The transmission shaft 413 can drive the upper horizontal worm 410 to rotate through the fixed bevel gear 411 and the transmission bevel gear 412 at the top. It can make the upper horizontal worm 410 push the upper fixed column 406 and the movable push plate 401 to move through the support lead screw 408, so that the two movable push plates 401 approach each other and clamp the battery body 3.

[0032] As Figure 1 and Figure 2 shown, a rubber pad 403 is adhesively bonded to the surface of the movable push plate 401. Between the movable push plate 401 and the clamping plate 402 are arranged a number of support springs 404. Inside the support spring 404 is inserted a guide slide bar 405. The movable push plate 401 and the clamping plate 402 are elastically connected through the support spring 404.

[0033] Working principle: Firstly, during use, the servo motor 414 can drive the coaxial worm gear 409 and the support lead screw 408 to rotate synchronously through the horizontal worm 410. The support lead screw 408 can drive the lead screw sleeve 407 and the fixed column 406 to move synchronously. Since the fixed column 406 is fixedly connected to the movable push plate 401, it can drive the movable push plate 401 to move. The bottom horizontal worm 410 can also drive the transmission shaft 413 to rotate through the fixed bevel gear 411 and the transmission bevel gear 412 at the bottom. The transmission shaft 413 can drive the horizontal worm 410 at the top to rotate through the fixed bevel gear 411 and the transmission bevel gear 412 at the top, so that the horizontal worm 410 at the top can drive the fixed column 406 and the movable push plate 401 at the top to move through the support lead screw 408, making the two movable push plates 401 approach each other and clamp the battery body 3.

[0034] Secondly, the two sides of the filter screen plate 503 and the movable pressure rod 505 can be correspondingly inserted into the inside of the sliding groove 504, and the movable pressure rod 505 can be pressed against the filter screen plate 503. By rotating the locking screw 508 to drive the movable pressure rod 505 to move, the insertion blocks 506 at both ends of the movable pressure rod 505 can be correspondingly inserted into the grooves 507 on both sides of the filter screen plate 503, thereby restricting the position of the filter screen plate 503.

[0035] Then, the external gas can be filtered by the filter screen plate 503 and introduced into the inside of the battery protection box 1 by the cooling fan 502, and discharged through a plurality of air holes 6, so that the gas circulates inside the battery protection box 1, which can be used to provide heat dissipation treatment for the battery body 3.
