[0030] Specifically, the lock buckle 4 is used to lock the cover plate 3 on the side plate 2, the shock absorber 6 is composed of a spring and a damper, the shock absorber 6 is used for shock absorption of objects, the lower vibration-proof plate 5 is used to absorb the vibration of the battery 11 in the up and down directions, and after the battery 11 is placed on the lower vibration-proof plate 5, the two groups of long vibration-proof plates 8 and the two groups of short vibration-proof plates 10 are used to absorb the vibration of the battery 11 in the horizontal direction; the cover plate 3 is flipped open, driving the L rod 12 to rotate synchronously, and the power is transmitted through the connecting rod 13 to drive the power slot plate 14 to move downward, and the insertion slide rod 15 first slides in the oblique line segment of the power slide slot 141, driving the insertion slide rod 1 5 moves toward the direction of the lower anti-vibration plate 5, the insertion slide bar 15 drives the locking plate 16 to move synchronously, and the card slot of the locking plate 16 contacts the lower anti-vibration plate 5 to prevent the lower anti-vibration plate 5 from moving up and down. Therefore, after the cover plate 3 is opened, the lower anti-vibration plate 5 will release the up and down anti-sway function to avoid the lower anti-vibration plate 5 moving up and down when the battery 11 is replaced again, which is convenient for replacing the battery 11; after the cover plate 3 is opened to a certain angle, that is, after the insertion slide bar 15 finishes sliding in the oblique segment of the power slide groove 141, the anti-sway function of the lower anti-vibration plate 5 is released, and the cover plate 3 is then opened, and the insertion slide bar 15 slides in the straight segment of the power slide groove 141.

[0031] The upper sides of the long anti-vibration plate 8 and the short anti-vibration plate 10 are both provided with inclined surfaces, and the inclined surfaces of the long anti-vibration plate 8 and the short anti-vibration plate 10 are convenient for placing the battery 11.

[0032] Specifically, when the battery 11 is placed on the lower anti-vibration plate 5, the battery 11 first contacts the inclined surfaces of the long anti-vibration plate 8 and the short anti-vibration plate 10, so that the long anti-vibration plate 8 and the short anti-vibration plate 10 move outward. After the battery 11 contacts the lower anti-vibration plate 5, the long anti-vibration plate 8 and the short anti-vibration plate 10 clamp the battery 11, and the upper inclined surfaces of the long anti-vibration plate 8 and the battery 11 hook the battery 11.

[0033] The anti-sway device is also provided with a gear 19, which is rotatably provided at the bottom of the base 1. The gear 19 forms a gear match with two racks 18. The racks 18 are provided on a toothed plate 17, and the toothed plate 17 is slidably provided at the bottom of the base 1. The toothed plate 17 is provided below the slide rod 15.

[0034] Specifically, the first sliding rod 15 of the anti-sway device moves, driving the first tooth plate 17 to move synchronously, and power is transmitted through the gear 19 and the two racks 18, so that the other group of sliding rods 15 and tooth plate 17 move synchronously in the direction of the lower anti-vibration plate 5, even if the slot of the other locking plate 16 also clamps the lower anti-vibration plate 5, so the two locking plates 16 of each group of anti-sway devices can clamp the lower anti-vibration plate 5 synchronously, so that the lower anti-vibration plate 5 can be more stable.

[0035] A driving block 20 is provided on the upper part of the locking plate 16 , and the driving block 20 is used to drive the seesaw 21 to rotate. A slideway is provided in the seesaw 21 , and the slideway of the seesaw 21 forms a sliding fit with the support frame 22 , and the upper end of the seesaw 21 forms a rotational fit with the long anti-vibration plate 8 .

[0036] Specifically, when the lock plate 16 moves toward the lower anti-vibration plate 5 , it drives the driving block 20 to move synchronously. The driving block 20 drives the seesaw 21 to rotate around the support frame 22 , so that the two groups of long anti-vibration plates 8 move away from the battery 11 .

[0037] A lever 23 is provided on the side of the driving block 20 . A separation wedge 24 is fixed on the side of the short vibration-proof plate 10 . An inclined surface is provided at the end of the separation wedge 24 . The lever 23 is used to drive the inclined surface of the separation wedge 24 .

[0038] Specifically, the driving block 20 drives the lever 23 to move synchronously, and the lever 23 drives the inclined surface of the separation wedge 24 to move the separation wedge 24 and the short vibration-proof plate 10 away from the battery 11 .

[0039] A heat dissipation bar 25 is disposed on the sides of the side plate 2 . A heat dissipation fan 26 is disposed on the side plate 2 , and the heat dissipation fan 26 is located at the heat dissipation bar 25 .

[0040] Specifically, the battery 11 generates a large amount of heat when working, and the heat dissipation bar 25 discharges the heat generated by the battery 11 from the heat dissipation fan 26 .

[0041] The long inner sides of the side plate 2 are slidably provided with long shift rods 27, and the two short inner sides of the side plate 2 are slidably provided with short shift rods 28. The head and tail of the long shift rod 27 and the short shift rod 28 are rotatably connected by the two ends of the ring rod 29. The two ends of the spring 1 30 are respectively connected to the long shift rod 27 and the side plate 2. The long shift rod 27 is provided with a long drive port 271, and the short shift rod 28 is provided with a short drive port 281. The middle parts of the long anti-vibration plate 8 and the short anti-vibration plate 10 are both provided with explosion-proof drive plates 31. The explosion-proof drive plate 31 on the long anti-vibration plate 8 is used to drive the long drive port 271, and the explosion-proof drive plate 31 on the short anti-vibration plate 10 is used to drive the short drive port 281.

[0042] Specifically, when the car encounters a collision, the battery 11 vibrates greatly in the horizontal direction. Even if the long anti-vibration plate 8 or the short anti-vibration plate 10 is displaced greatly, the explosion-proof driving plate 31 is also displaced greatly. The explosion-proof driving plate 31 is used to drive the long drive port 271 or the short drive port 281 to move the long shift rod 27 or the short shift rod 28, and transmit power through the ring rod 29. When one explosion-proof driving plate 31 contacts the long drive port 271 or the short drive port 281, all the long shift rods 27 and the short shift rods 28 move.

[0043] A long hook 272 is provided on the long shift rod 27, a short hook 282 is provided on the short shift rod 28, four hook rods 32 are provided at the bottom of the square plate 33, the hook rods 32 on the long side of the square plate 33 are used to hook the long hook 272, the hook rods 32 on the short side of the square plate 33 are used to hook the short hook 282, a long blocking plate 34 is provided on the upper part of the long side of the square plate 33, the long blocking plate 34 is used to be inserted into the long side cooling fan 26, a short blocking plate 35 is provided on the upper part of the short side of the square plate 33, the short blocking plate 35 is used to be inserted into the short side cooling fan 26, the four corners of the square plate 33 form a sliding fit with the sliding rod 36, the sliding rod 36 is fixedly arranged on the side plate 2, and the two ends of the pull rod 37 are connected between the square plate 33 and the sliding rod 36.

[0044] Specifically, after the long shift rod 27 and the short shift rod 28 are moved, all the hook rods 32 are unhooked from the long hook openings 272 and the short hook openings 282, and the pull rod 37 provides pulling force to drive the square plate 33 to move upward along the slide rod 36, so the long blocking plate 34 and the short blocking plate 35 are inserted into the corresponding cooling fan 26 to block the corresponding cooling bar 25, and the long blocking plate 34, the short blocking plate 35 and the side plate 2 are tightly sealed, thereby ensuring that the explosion gas flame of the battery 11 does not leak out.

[0045] An anti-shift opening 273 is provided on the long shift rod 27, and a latch plate 39 is used to be inserted into the anti-shift opening 273. The latch plate 39 is slidably arranged on the side plate 2. Both ends of the spring 240 are respectively connected to the side plate 2 and the latch plate 39. A wedge block 38 is provided on the upper part of the driving block 20, and the inclined surface of the wedge block 38 is used to drive the latch plate 39 to move.

[0046] Specifically, the drive block 20 moves synchronously with the wedge block 38 in the direction of the lower vibration isolation plate 5, the inclined surface of the wedge block 38 drives the latch plate 39 to move upward, the spring 2 40 is stretched, and the latch plate 39 is inserted into the anti-displacement opening 273 to prevent the long displacement rod 27 from moving. Therefore, when the cover plate 3 is opened to replace the battery 11, the explosion-proof function is prevented from being activated.

[0047] Working principle: when replacing the battery 11, unlock the lock 4, open the cover 3, the cover 3 drives the L rod 12 to rotate synchronously, transmits power through the connecting rod 13, drives the power slot plate 14 to move downward, the insertion slide bar 15 first slides in the oblique line segment of the power slide slot 141, drives the insertion slide bar 15 to move in the direction of the lower anti-vibration plate 5, the insertion slide bar 15 drives the lock plate 16 to move synchronously, the card slot of the lock plate 16 contacts the lower anti-vibration plate 5 to prevent the lower anti-vibration plate 5 from moving up and down, the insertion slide bar 15 drives, so after the cover 3 is opened, the lower anti-vibration plate 5 will release the up and down anti-sway function to prevent the lower anti-vibration plate 5 from moving up and down when the battery 11 is replaced, which is convenient for replacing the battery 11; the insertion slide bar 15 drives the first tooth plate 17 to move synchronously, and transmits power through the gear 19 and the two racks 18, so that the other group of insertion slide bars 15 and tooth plates 17 move synchronously in the direction of the lower anti-vibration plate 5, even if the slot of the other locking plate 16 also clamps the lower anti-vibration plate 5, so the two locking plates 16 of each group of anti-sway devices can clamp the lower anti-vibration plate 5 synchronously, so that the lower anti-vibration plate 5 can be more stable.

[0048] The locking plate 16 drives the driving block 20 to move synchronously, and the driving block 20 drives the seesaw 21 to rotate around the support frame 22, so the two groups of long anti-vibration plates 8 move in the direction away from the battery 11, and the driving block 20 drives the lever 23 to move synchronously, and the lever 23 drives the inclined surface of the separation wedge 24, so that the separation wedge 24 and the short anti-vibration plate 10 move in the direction away from the battery 11, so the long anti-vibration plate 8 and the short anti-vibration plate 10 release the original battery 11, take out the original battery 11, and place a new battery 11 on the lower anti-vibration plate 5. If the battery 11 first contacts the inclined surfaces of the long anti-vibration plate 8 and the short anti-vibration plate 10, the long anti-vibration plate 8 and the short anti-vibration plate 10 are moved outward to facilitate the placement of the battery 11. After the battery 11 contacts the lower anti-vibration plate 5, the long anti-vibration plate 8 and the short anti-vibration plate 10 clamp the battery 11, and the upper inclined surfaces of the long anti-vibration plate 8 and the battery 11 hook the battery 11.

[0049] When the battery 11 is working, the battery 11 generates a large amount of heat, and the heat dissipation bar 25 discharges the heat generated by the battery 11 from the heat dissipation fan 26; at the same time, due to the vibration of the car, the lower vibration isolation plate 5 is used to absorb the vibration of the battery 11 in the vertical direction, and the two groups of long vibration isolation plates 8 and the two groups of short vibration isolation plates 10 are used to absorb the vibration of the battery 11 in the horizontal direction.

[0050] When the car encounters a collision, the battery 11 is at risk of explosion, and the battery 11 vibrates greatly in the horizontal direction. Even if the displacement of the long anti-vibration plate 8 or the short anti-vibration plate 10 is large, the explosion-proof driving plate 31 is driven to have a large displacement. The explosion-proof driving plate 31 is used to drive the long drive port 271 or the short drive port 281 to move the long shift rod 27 or the short shift rod 28, and transmit power through the ring rod 29. When one explosion-proof driving plate 31 contacts the long drive port 271 or the short drive port 281, all the long shift rods 27 and the short shift rods 28 move; therefore, all the hook rods 32 are unhooked from the long hook port 272 and the short hook port 282, and the pull rod 37 provides a pulling force to drive the square plate 33 to move upward along the slide rod 36. Therefore, the long blocking plate 34 and the short blocking plate 35 are inserted into the corresponding heat dissipation fan 26 to block the corresponding heat dissipation bar 25. The long blocking plate 34, the short blocking plate 35 and the side plate 2 are tightly sealed, so as to ensure that the explosion gas flame of the battery 11 does not leak out.

[0051] Taking into account that when the battery 11 is replaced, the long anti-vibration plate 8 and the short anti-vibration plate 10 may be displaced significantly, which may trigger the explosion-proof function by mistake. Therefore, when the cover 3 is opened, the drive block 20 moves synchronously with the wedge block 38 in the direction of the lower anti-vibration plate 5, and the inclined surface of the wedge block 38 drives the latch plate 39 to move upward, the spring 240 is stretched, and the latch plate 39 is inserted into the anti-displacement opening 273 to prevent the long displacement rod 27 from moving, ensuring that the hook rod 32 is not decoupled from the long hook opening 272 and the short hook opening 282. Therefore, when the cover 3 is opened to replace the battery 11, the explosion-proof function is avoided from being activated.

[0052] Any matters not described in the present invention are applicable to the prior art.
