Then the first electric push rod 303 moves downward, driving the second connecting frame 306 and corresponding components to move downward, so that the arc guide plate 312, the brushing roller 316 and the water absorption roller 317 can all contact the surface of the new energy vehicle. The brushing roller 316 first contacts the vehicle body near the battery module. At this time, the output shaft of the first motor 313 drives The water absorbing roller 317 rotates, and the water absorbing roller 317 drives the second transmission wheel 315 to rotate through the first transmission wheel 314, and then the second transmission wheel 315 drives the scrubbing roller 316 to rotate. When the scrubbing roller 316 rotates, the flexible paddles evenly distributed on its outer surface are used to scrub the surface of the vehicle body, thereby removing dust. At the same time, the arc-shaped guide plate 312 sprays atomized water obliquely downward at the position where the scrubbing roller 316 contacts the vehicle body, absorbing the dust, thereby preventing the dust from spreading in the air. Then the waste water flows downward to the arc-shaped guide plate 312, and then Afterwards, it is transferred to the collection box 309 for collection. Furthermore, after the dust removal is completed, the water absorption roller 317 is rotated to move downward to contact the previously cleaned car body. The water absorption roller 317 removes the water on the surface of the car body through the water-absorbing sponge on its outer surface. At the same time, the air blower 307 sends air obliquely downward to quickly dry the surface of the car body, thereby completing the drying work of the car body. Further, the two groups of the first electric push rods 303 drive the second connecting frame 306 to move upward to the initial position and further move upward, so that the water absorption roller 317 can be squeezed and contacted with the squeezing roller 304, thereby The water in the absorbent sponge on the absorbent roller 317 is squeezed out and falls onto the brushing roller 316, allowing the brushing roller 316 and the absorbent roller 317 to rotate, thereby completing the self-cleaning of the brushing roller 316 and the dewatering of the absorbent sponge of the absorbent roller 317. The baffle 305 is used for drainage. In this way, the dust on the surface of the new energy vehicle can be removed, and the dust can be adsorbed to prevent it from being transferred to the air, and the dust removal part can be dried, so that the battery module will not be stained with dust when it is taken out. At the same time, the cleaning parts can be self-cleaned and the drying parts can be self-dehydrated.

It can be understood that the third connecting frame 401 is connected to two groups of the cylinders 301 on one side facing the top plate 11 to support the cylinders 301. Two groups of second electric push rods 402 and two groups of third electric push rods 403 are connected to the side of the third connecting frame 401 facing away from the top plate 11. The second electric push rods 402 and the third electric push rods 403 are located on opposite side edges of the third connecting frame 401. The ends of the two groups of second electric push rods 402 away from the third connecting frame 401 are connected to the first pressure plate 404, and the ends of the two groups of third electric push rods 403 away from the third connecting frame 401 are connected to the second pressure plate 405. The loading plate 409 is arranged directly below the third connecting frame 401. The bottom plate 1 is bolted to two groups of symmetrically distributed third electric slide rails 406. The two groups of third electric slide rails 406 are located on opposite sides of the loading plate 409 and are respectively slidably connected to a group of first electric sliders 407. The two groups of first electric sliders 407 are connected to the fourth connecting frame 408. Four groups of springs 410 are fixedly connected to the four corners below the loading plate 409. , the four groups of springs 410 are fixedly connected to the third connecting plate 411 below, and the third connecting plate 411 is connected to two groups of distance sensors 412 on a side facing the loading plate 409. Preferably, the two groups of distance sensors 412 are located at opposite side edges of the third connecting plate 411, and the side of the third connecting plate 411 facing away from the loading plate is connected to the electric turntable 413. Preferably, the electric turntable 413 is located at the center of the third connecting plate 411, and the side of the electric turntable 413 facing away from the third connecting plate 411 is connected to the fourth connecting plate 414. Four groups of fourth electric push rods 415 are fixedly connected to the side of the fourth connecting plate 414 facing away from the third connecting plate 411. The four groups of fourth electric push rods 415 are located at the four corners of the fourth connecting plate 414. The four groups of fourth electric push rods 415 pass through the bottom plate 1 and are connected to the support plate 13. Twelve groups of openings are symmetrically provided on both sides of the fourth connecting frame 408.

[0054] The dismantling assembly used to remove the battery module is installed on the fourth connecting frame 408, with the working direction facing the posture correction system. The dismantling assembly is adapted to the type of the battery module that needs to be removed. First, the two groups of the third electric slide rails 406 drive the fourth connecting frame 408 to move through the two groups of the first electric sliders 407, and then drive the dismantling assembly to move. The dismantling assembly moves to the battery module of the new energy vehicle, and the battery module is taken out of the new energy vehicle. Then, the fourth connecting frame 408 is returned to its initial position, and the battery module is transferred to the top of the carrier plate 409. Further, the fourth connecting frame 408 is moved to the top of the carrier plate 409. The fourth electric push rod 415 of the group pushes the fourth connecting plate 414 upward at the same time, thereby driving the battery module to move upward and contact the middle part of the lower surface of the third connecting frame 401, and then the distance between the carrier plate 409 and the third connecting plate 411 is detected by the two groups of distance sensors 412 to determine whether the battery module is bulging or concave. If the battery module is bulging, the distance between the carrier plate 409 and the third connecting plate 411 is reduced. If the battery module is concave, the distance between the carrier plate 409 and the third connecting plate 411 is increased. The four groups of springs 410 cooperate to expand and contract, further After the inspection is completed, if the battery module is normal, the battery module is lowered to the working height of the secondary dust removal system. Further, the electric turntable 413 drives the third connecting plate 411 to rotate, and the third connecting plate 411 drives the loading plate 409 to rotate through the four groups of springs 410, thereby driving the upper battery module to rotate so that the connector side of the battery module can face the secondary dust removal system. Further, the two groups of the second electric push rods 402 drive the first pressure plate 404 to move obliquely downward, and the two groups of the third electric push rods 403 synchronously drive the second pressure plate 405 It moves obliquely downward, so that the two sides of the battery module are fixed downward by the first pressure plate 404 and the second pressure plate 405, thereby cooperating with the loading plate 409 to complete the fixation of the battery module. In this way, when the secondary dust removal system is working, the battery module will not move. Furthermore, when the charged battery module is placed in the new energy vehicle, the fourth connecting frame 408 drives the removal component to move toward the posture correction system, so that the charged battery module is inserted therein, and the new battery module is fixed in the new energy vehicle by removing the component, thereby realizing the disassembly, detection, and transfer of the battery module.

The outer annular surface of the fourth transmission wheel 506 is connected to the fifth transmission wheel 512 through a belt transmission, and the fifth transmission wheel 512 is sleeved on the second rotating rod 513, and the second rotating rod 513 is rotatably connected to the sixth connecting frame 510, the end of the second rotating rod 513 away from the fifth transmission wheel 512 is connected to the first bevel gear 514, the first bevel gear 514 is meshed and connected to the second bevel gear 515, the second bevel gear 515 is connected to the cleaner 516, and the fifth connecting frame 503 is fixedly connected to the optical rod 517 on the side facing the sixth connecting frame 510, and the outer surface of the optical rod 517 is connected to two groups of the sliding sleeves 518, the sliding sleeves 518 are slidably connected to the optical rod 517, and the two groups of the sliding sleeves 518 are fixedly connected to the sixth connecting frame 510.

[0056] The fourth electric slide rail 501 drives the fifth connecting frame 503 to move through the second electric slider 502, thereby driving the cleaner 516 to move to the dust removal position where it can dock with the connector of the battery module. The output shaft of the second motor 504 drives the third transmission wheel 505 to rotate, and the outer annular surface of the third transmission wheel 505 drives the fourth transmission wheel 506 to rotate through a belt. The fourth transmission wheel 506 drives the fifth transmission plate 508 to be transmitted through the first rotating rod 507, and then the fifth transmission plate 508 drives the sixth connecting frame 510 to reciprocate horizontally through the sixth transmission plate 509. At this time, the optical rod 517 and the two groups of the sliding sleeves 518 slide with each other for guidance. Further, when the sixth connecting frame 510 reciprocates horizontally, the outer annular surface of the fourth transmission wheel 506 drives the fifth transmission wheel 512 to rotate through a belt. The second rotating rod 513 drives the first bevel gear 514 to rotate, and the first bevel gear 514 drives the cleaner 516 to rotate through the second bevel gear 515, so that the cleaner 516 can also move back and forth while rotating, and then the cleaner 516 uses the fine brush on the outer surface to remove dust on the connector of the electric hammer module. Furthermore, the sixth connecting frame 510 moves back and forth in a small range, and the belt between the fourth transmission wheel 506 and the fifth transmission wheel 512 can still transmit power. The dust swept by the cleaner 516 is sucked away by the suction device 511, and the dust in the air is also sucked away. In this way, it can be ensured that there is no dust on the connector of the battery module, and the dust on the connector of the battery module is removed. At the same time, the dust in the air is removed, and the connector of the battery module is prevented from being stained with dust, thereby ensuring the safe use of the battery module.

[0058] When this system is working, the fifth electric slide rail 602 is driven to move up and down by the two groups of the fifth electric push rods 601, and the fifth electric slide rail 602 drives the electric clamp 604 to move horizontally through the third electric slider 603, so that the electric clamp 604 can move up and down and horizontally, and the battery module after dust removal is clamped by the electric clamp 604. At this time, the external connector of the battery module after changing its orientation again is facing the charging compartment 7, and the battery module is inserted into the charging compartment 7 through the electric clamp 604. The charged battery module in the charging compartment 7 is taken out by the electric clamp 604 and placed on the loading plate 409, thereby realizing the function of transferring the battery module.

[0059] The first limiting block 211 and the second limiting block 212 are both in the shape of an isosceles trapezoid. When the new energy vehicle runs over the first limiting block 211 and the second limiting block 212, they can protect the first limiting long plate 207 and the second limiting long plate 208. At the same time, they are elastic and can also protect themselves.

[0060] The first transverse bar group 209 and the second transverse bar group 210 are both composed of fourteen groups of long bars with semi-elliptical cross-sections. Blank areas are set in the middle of the first transverse bar group 209 and the second transverse bar group 210. The bottom plate 1 is grooved, and the grooves correspond to the positions of the blank areas, so that when the wheels of the new energy vehicle are parked, they can be better transferred to the grooves of the bottom plate 1. At the same time, when the wheels are moved laterally, the resistance they encounter is smaller.

[0061] The air outlet of the air blower 307 and the water outlet of the water blower 308 are both oriented obliquely downward. The water outlet of the water blower 308 is provided with an atomizer.

[0062] The outer surface of the scrubbing roller 316 is interlaced with flexible paddles, while the outer surface of the absorbent roller 317 is provided with a water-absorbing sponge. The flexible paddles scrub the vehicle body without damaging it, while the water-absorbing sponge absorbs water from the vehicle surface.
