Description

Technical Field

[0002] Amid the rapid growth of the new energy vehicle industry, efficient replacement and maintenance of battery packs, core components of vehicle powertrains, have become a key focus of the industry. Currently, battery pack designs for new energy vehicles produced by different manufacturers exhibit significant differences, particularly in the spacing of battery pack mounting bolts, which vary significantly depending on the vehicle platform, battery capacity, and structural layout.

[0003] Traditional disassembly mechanisms often utilize fixed brackets or single-drive screw structures, making it difficult to flexibly adjust the lateral position based on the actual bolt spacing. For example, some devices restrict the movement of the disassembly head via fixed guide rails. This results in the device being unable to accurately align the bolts when the bolt spacing exceeds the preset range, making the disassembly operation impossible. This limitation forces repair companies or automakers' after-sales departments to equip multiple sets of specialized replacement equipment with varying specifications to accommodate diverse vehicle models. This not only consumes significant storage space but also significantly increases equipment procurement and maintenance costs. Summary of the Invention

[0030] As can be seen from the above, by setting four hydraulic cylinders 201, the height of the support plate 202 can be adjusted to adapt to the height of the battery pack installation position of different vehicle models; the servo motor 204 drives the first bidirectional screw 205 to rotate, and at the same time, cooperates with the synchronous pulley 208 and the belt 209 to drive the second bidirectional screw 206 to rotate, and then realizes the synchronous rotation of the first bidirectional screw 205 and the second bidirectional screw 206, so that the movable plate 210 moves left and right under the guidance of the limit rod 207, thereby adjusting the spacing between the movable plates 210, and the first electric push rod 213 can push the disassembly component 3 again, providing the disassembly component 3 with a lateral position adjustment function, thereby being able to adapt to the different spacings of the battery pack fixing bolts in the vertical and horizontal directions.

[0033] As can be seen from the above, the output ends of the four hydraulic cylinders 201 are moved upward to align the hexagonal groove 304 on the top of the rotating column 303 with the hexagonal head of the battery pack bolt, and then the electric motor 302 drives the rotating column 303 to rotate to achieve the removal or installation of the bolt; in the anti-drop component 4, the second electric push rod 402 pushes the second fixed seat 403 to move downward, and drives the clamping jaw 404 to rotate around the shaft 406 through the connecting rod 405, so that the clamping jaw 404 clamps the bolt head to prevent the bolt from falling during the disassembly process, thereby improving the safety and reliability of the operation.

[0034] Example 3:

[0035] Please refer to Figure 1 and Figure 6 As shown, the cleaning assembly 5 includes a long plate 501 and a U-shaped frame 502 fixedly connected to both sides of the inner wall of the square groove 101. The inner cavity of the U-shaped frame 502 is fixedly connected to a rotating motor 503 and a guide rod 504. The output end of the rotating motor 503 is covered with a reciprocating screw 505 through a coupling. The outer rings of the reciprocating screw 505 and the guide rod 504 are covered with a square seat 506. The middle of the square seat 506 is penetrated by a hole for connecting to the reciprocating screw 50 5 and the guide rod 504 are adapted to the screw hole 507 and the guide hole 508, one side of the square seat 506 is rotatably connected to the cleaning roller 509 through a bearing, the top of the long plate 501 is fixedly connected to the blower 510 and the booster blow pump 511, a delivery pipe 512 is sleeved between the booster blow pump 511 and the blower 510, the air outlet end of the booster blow pump 511 is sleeved with a pipe body 513, and the top of the pipe body 513 is sleeved with multiple nozzles 514.

[0036] As can be seen from the above, the rotating motor 503 drives the reciprocating screw 505 to rotate, so that the square seat 506 moves back and forth along the reciprocating screw 505 under the guidance of the guide rod 504, driving the cleaning roller 509 to roll and clean the surface of the battery pack installation position to remove dust and debris; the blower 510 conveys air to the booster blower pump 511 through the delivery pipe 512, and the booster blower pump 511 pressurizes the air. After pressurization, high-pressure gas is formed and ejected through the pipe body 513 and the nozzle 514, further blowing away small debris that has not been removed by the cleaning roller 509, ensuring that the installation surface is clean, and providing a good installation environment for battery pack replacement.

[0037] Working principle: The first bidirectional lead screw 205 is driven to rotate by the servo motor 204, and the second bidirectional lead screw 206 is driven to rotate synchronously by the synchronous pulley 208 and the belt 209. Since the threads on the first bidirectional lead screw 205 and the second bidirectional lead screw 206 have opposite rotation directions, the movable plate 210 can be guided by the limit rod 207 and moved to the sides or the middle along the first bidirectional lead screw 205 and the second bidirectional lead screw 206, thereby adjusting the vertical spacing between the movable plates 210. At the same time, the output end of the first electric push rod 213 can push and adjust the disassembly component 3 horizontally, so that it can adapt to the battery pack The spacing of the fixing bolts in the vertical and horizontal directions is different. At this time, the four hydraulic cylinders 201 are started, and the support plate 202 is pushed up and down through its output end, driving the upper disassembly component 3 to rise and fall as a whole to adapt to the installation height of the battery pack of different models. The hexagonal groove 304 on the top of the rotating column 303 is inserted into the hexagonal head of the battery pack bolt. After the electric motor 302 is started, the rotating column 303 is driven to rotate through the coupling to realize the disassembly of the bolt. After the disassembly is completed, the second electric push rod 402 pushes the second fixing seat 403 downward, and drives the clamping claw 404 to rotate around the shaft 406 through the connecting rod 405, so that the clamping claw 404 By tightening the bolt head, the clamping claw 404 can prevent the bolt from falling even if it is loose, avoiding unnecessary impact caused by the loss of the bolt. After the bolt is removed, the old battery pack falls from the battery slot on the bottom of the new energy vehicle onto the carrier plate 102, and then the four hydraulic cylinders 201 drive it downward to remove the old battery pack, and then the new battery pack is placed on the carrier plate 102 at the position corresponding to the battery slot on the bottom of the new energy vehicle, and the four hydraulic cylinders 201 drive it upward again to push the new battery pack and the bolt into the battery slot and the bolt hole respectively, and then release the clamping claw 404, and the electric motor 302 reverses to fix the bolt in the bolt hole. The new battery pack is fixedly installed in the battery slot. After installation, the rotating motor 503 drives the reciprocating screw 505 to rotate. The square seat 506 moves back and forth along the reciprocating screw 505 under the restriction of the guide rod 504, driving the cleaning roller 509 to roll on the surface of the battery pack installation position, removing dust, debris and larger debris through friction. The air generated by the blower 510 enters the booster blowing pump 511 through the delivery pipe 512, and after being pressurized, high-pressure air flow is ejected through the tube body 513 and the nozzle 514 to blow away the fine particles not removed by the cleaning roller 509, ensuring that the installation surface is clean and preventing debris from affecting the use effect of the battery pack.
