Description

Technical Field

[0001] The present invention relates to the technical field of battery combination, and specifically to a battery pack combination device for new energy vehicles. Background Art

[0002] The battery pack of a new energy vehicle is the core component of an electric vehicle, directly affecting the vehicle's performance, cruising range, and safety. The battery pack of a new energy vehicle is usually composed of multiple battery modules. During the production process, the battery packs are usually sequentially placed into the battery housing, and then the battery packs are sequentially connected to form a battery pack. When the existing battery pack combination device for new energy vehicles is in use, the battery pack is usually directly clamped into the housing by a clamping structure. During the clamping process, after clamping and placing the previous battery pack, the clamping structure usually needs to be moved back to the conveying position of the battery pack and then clamp the next battery pack. In this way, each battery pack needs to be clamped and placed one by one, and the combination speed is relatively slow, which is not conducive to the rapid combination of battery packs.

When placing the battery pack into the battery housing, the connection boxes can be grouped in pairs, and two battery packs can be placed into the battery housing at the same time. When placing battery packs of different sizes and the distance between the two battery packs is small, the positioning screw rod can be screwed out, and then the sliding seat can be moved downward. After adjusting the distance between a group of two connection boxes, the sliding seat can be moved upward, so that the tooth engaging block is inserted into the tooth engaging belt again. Then, the positioning screw rod is screwed into the connection seat again, the connection seat is connected with the abutting seat, and the connection mechanism is reconnected to the transmission mechanism. In this way, the placement distance between adjacent two battery packs can be adjusted as needed, and the use is relatively flexible. Description of the Drawings

Detailed implementation manners

[0061] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0062] Please refer to Figures 1-14 , in the embodiment of the present invention, a battery pack combination device for a new energy vehicle includes a conveying module 100, two second conveyors 200, and a clamping module 300;

[0063] The conveying module 100 can convey battery boxes. The conveying module 100 includes a first conveyor 110 and two fixing frames 120. The bottoms of the two fixing frames 120 are fixedly connected to the top surface of the first conveyor 110. The two second conveyors 200 are respectively arranged on both sides of the conveying module 100. A limiting frame 130 is fixedly connected to the bottom of the opposite surfaces of the two fixing frames 120. The fixing frame 120 can support the limiting frame 130. A plurality of opening grooves are formed on the top surface of the limiting frame 130. A second guiding frame 132 and two first guiding frames 131 are fixedly connected to the inner side surface of the opening groove. The second guiding frame 132 is located between the two first guiding frames 131. The battery pack can be guided through the inclined surfaces on the first guiding frame 131 and the second guiding frame 132;

[0064] The clamping module 300 is arranged on the top of the two second conveyors 200. The clamping module 300 straddles the top of the conveying module 100. The clamping module 300 is located between the two fixing frames 120. The clamping module 300 includes a transmission mechanism 310 and a plurality of connecting boxes 320. A connecting mechanism 330 is arranged on the top of the connecting box 320. The connecting box 320 can be connected to the transmission mechanism 310 through the connecting mechanism 330. A sliding frame 340 is slidably connected to the inner side surface of the connecting box 320. Two clamping plates 350 are slidably connected to the inner bottom surface of the sliding frame 340. Two toothed plates 360 slidably connected to the inner side surface of the connecting box 320 are fixedly connected to the top surface of the sliding frame 340. Two rotating rods 370 are arranged inside the connecting box 320. A rolling gear 371 fixedly sleeved on the side surface of the rotating rod 370 and drivingly connected to the bottom of the adjacent toothed plate 360 is arranged between the two toothed plates 360.

[0065] Specifically, the battery shell can be transported by the conveyor 110, and the battery pack can be transported by the two conveyors 200, and the connecting box 320 can be circulated along the transmission mechanism 310 through the connecting mechanism 330. When the connecting box 320 moves to the top of a conveyor 200, the two clamping plates 350 can move toward each other, so that the two clamping plates 350 clamp the battery pack, and the connecting box 320 can continue to move along the transmission mechanism 310, and the conveyor 200 can continue to transport the battery pack. After the battery pack is separated from the conveyor 200, the battery pack can be clamped and continued to be transported by the clamping plates 350. When the battery pack is moved to the top of the battery shell, the transmission mechanism 310 can stop continuing to move the connecting box 320, so that the battery pack stays on the top of the battery shell. At this time, the two rotating rods 370 can be rotated, and the rotating rods 370 can drive the rolling gear 371 to rotate, thereby toggling the tooth plate 360 ​​to move downward, so that the slide The movable frame 340 and the clamping plate 350 move downward so that the battery pack is placed downward into the battery housing to assemble the battery pack, and then the two clamping plates 350 move away from each other to loosen the battery pack. After the assembly is completed, the sliding frame 340 can be moved upward to the original height, and then the connecting box 320 and the sliding frame 340 can continue to be moved through the transmission mechanism 310. When the connecting box 320 moves to the top of another conveyor 200, the clamping plate 350 can be used to clamp the battery pack on the other conveyor 200 to carry out the next combination. During the assembly, the battery pack can be clamped by the remaining clamping plates 350 located at the top of the conveyor 200, so that the combination and clamping of the battery pack are carried out simultaneously, and by circulating a plurality of connecting boxes 320 along the transmission mechanism 310, the battery packs on the two conveyors 200 can be clamped at the same time, which is beneficial to improve the battery pack combination speed and facilitate the rapid combination of battery packs.

[0066] Embodiment 1

[0067] like Figures 10-14As shown, in this embodiment, a first linkage shaft 321 is rotatably connected to the inner side surface of the connection box 320. One end of the first linkage shaft 321 is fixedly sleeved with a first connection gear 322. Two positioning frames 324 rotatably connected to the two rotating rods 370 are fixedly connected to the inner top surface of the connection box 320. The overall shape of the positioning frame 324 is U-shaped. Two toothed plates 360 are located between the two positioning frames 324. The positioning frame 324 can limit the rotating rod 370. The side surface of the first linkage shaft 321 is rotatably connected to the inner side surfaces of the two positioning frames 324. Two positioning rods 325 are fixedly connected to the bottom of the inner side surfaces of the two positioning frames 324. The bottoms of the two positioning frames 324 are connected to each other through the positioning rods 325. A connecting rod 326 is rotatably connected to the positioning rods 325. The positioning rods 325 can support the connecting rod 326. A first worm 323 is fixedly sleeved on the side surface of the first linkage shaft 321. A first worm gear 327 meshing with the first worm 323 is fixedly sleeved on the side surface of the connecting rod 326. Bevel gears 380 are fixedly sleeved at both ends of the connecting rod 326 and at the ends of the two rotating rods 370. And adjacent two bevel gears 380 are meshed and driven. The two rotating rods 370 are linked through the connecting rod 326 and the bevel gears 380. And the two rotating rods 370 rotate in opposite directions. The rotation of the connecting rod 326 is restricted by the first worm 323 and the first worm gear 327, so as to restrict the rotation of the rotating rod 370. Furthermore, the height of the toothed plate 360 is maintained through the rolling gear 371, and the heights of the sliding frame 340 and the clamping plate 350 are restricted;

[0068] An adjusting shaft 343 is rotatably connected to the inner bottom surface of the sliding frame 340. A strip-shaped groove is provided on the side surface of the sliding frame 340 corresponding to the first linkage shaft 321. The first linkage shaft 321 passes through the inside of the strip-shaped groove. A second worm gear 345 and an adjusting gear 346 are fixedly sleeved on the side surface of the adjusting shaft 343. Rack bars 351 meshing with the adjusting gear 346 are fixedly connected to the opposite surfaces of the two clamping plates 350. A second linkage shaft 341 is rotatably connected to the bottom of the inner side surface of the sliding frame 340. A second worm 344 meshing with the second worm gear 345 is fixedly sleeved on the side surface of the second linkage shaft 341. A second connection gear 342 is fixedly sleeved at one end of the second linkage shaft 341. The rotation of the adjusting shaft 343 is restricted by the second worm 344 and the second worm gear 345, so as to restrict the positions of the two clamping plates 350. The second connection gear 342 is located outside the sliding frame 340, and the first connection gear 322 is located outside the connection box 320.

[0069] During specific implementation, the second linkage shaft 341 can be rotated. The second linkage shaft 341 can drive the second worm 344 to rotate. The second worm 344 can drive the adjustment shaft 343 to rotate through the second worm gear 345. The adjustment shaft 343 can drive the adjustment gear 346 to rotate. The adjustment gear 346 can move two racks 351. Since the adjustment gear 346 is located between the two racks 351 and the moving directions of the two racks 351 are opposite, the two clamping plates 350 can move towards each other to clamp the battery pack. When it is necessary to lower the battery pack, the first linkage shaft 321 can be rotated. The first linkage shaft 321 can drive the first worm 323 to rotate. The first worm 323 can drive the connecting rod 326 to rotate through the first worm gear 327. The connecting rod 326 drives two rotating rods 370 to rotate through the bevel gears 380. The rotating rods 370 can drive the rolling gears 371 to rotate, thereby moving the toothed plate 360 and moving the sliding frame 340 downward, and then lowering the sliding frame 340 and the clamping plate 350. After the combination is completed, the first linkage shaft 321 can be rotated in the reverse direction to raise the sliding frame 340 and the clamping plate 350 again.

[0070] Two limit blocks can be fixedly arranged on the inner bottom surface of the sliding frame 340 corresponding to the adjustment shaft 343. The opposite surfaces of the two limit blocks are both slidably connected to the side surfaces of the adjacent racks 351, so as to limit the moving direction of the racks 351 through the limit blocks, make the racks 351 closely adhere to the adjustment gear 346. Limit boxes are fixedly arranged on both the outside of the connection box 320 and the sliding frame 340. The first connection gear 322 and the second connection gear 342 are both located in the corresponding limit boxes.

[0071] As Figures 5-6 shown, in this embodiment, two first driving mechanisms 140 are arranged inside the fixing frame 120, and a second driving mechanism 210 is arranged on the top of the second conveyor 200. The structure of the second driving mechanism 210 is the same as that of the first driving mechanism 140;

[0072] The first driving mechanism 140 includes a driving frame 141, two rotating frames 144, four connecting shafts 142, four driving gears 143, two driving motors 148, two fixed shafts 145, two limit frames 146, and two torsion springs 147;

[0073] The driving frame 141 is fixedly connected to the inner side surface of the fixed frame 120. Two rotating frames 144 are respectively arranged at the top and bottom of the driving frame 141. Four connecting shafts 142 are respectively rotatably connected to the inner side surfaces of the two rotating frames 144. Four driving gears 143 are respectively fixedly sleeved on the four connecting shafts 142. Adjacent two driving gears 143 are meshed. There are two connecting shafts 142 and two driving gears 143 arranged inside the rotating frame 144. The driving gears 143 are fixedly sleeved on the connecting shafts 142, and the two driving gears 143 located in the same rotating frame 144 are meshed. Two driving motors 148 are respectively fixedly connected to the top and bottom of the inner side surface of the driving frame 141. The output ends of the driving motors 148 are in transmission connection with the ends of the adjacent connecting shafts 142. Two fixed shafts 145 are respectively fixedly connected to the side surfaces of the two rotating frames 144. The inner side surface of the fixed shaft 145 is rotatably connected to the side surface of the adjacent connecting shaft 142. Two limiting frames 146 are respectively fixedly connected to the top and bottom of the inner side surface of the driving frame 141. The inner side surface of the limiting frame 146 is rotatably connected to the side surface of the adjacent fixed shaft 145. Two torsion springs 147 are respectively arranged inside the two limiting frames 146. The torsion springs 147 are located between the inner side surface of the adjacent limiting frame 146 and the side surface of the fixed shaft 145. Under the action of the torsion springs 147, the angle of the fixed shaft 145 can be maintained, so as to maintain the angle of the rotating frame 144, and further maintain the angle of the driving gear 143.

[0074] During specific implementation, when the connection box 320 moves to the top of the conveying module 100, under the action of the torsion spring 147, the first connection gear 322 can be kept meshed with one of the driving gears 143 at its top. At this time, the corresponding connecting shaft 142 can be driven to rotate by the driving motor 148 at the top. The connecting shaft 142 can drive the driving gear 143 thereon to rotate, and the two driving gears 143 can rotate synchronously. In this way, the first connection gear 322 can be toggled to rotate by the driving gear 143, so that the first linkage shaft 321 rotates, the sliding frame 340 and the clamping plate 350 are lowered, and the battery pack is lowered into the battery case. The sliding frame 340 can drive the second linkage shaft 341 to move downward, so that the second connection gear 342 moves downward to the position of the bottom rotating frame 144. Under the action of the torsion spring 147, the second connection gear 342 can be kept meshed with one of the driving gears 143 at its bottom. At this time, the corresponding connecting shaft 142 can be driven to rotate by the bottom driving motor 148, so that the two driving gears 143 at the bottom rotate, and thus the second connection gear 342 rotates. The second connection gear 342 can drive the second linkage shaft 341 to rotate. When the second linkage shaft 341 rotates, the two clamping plates 350 can move away from each other to loosen the battery pack. Then, the corresponding connecting shaft 142 can be driven to rotate reversely by the top driving motor 148, so that the first linkage shaft 321 rotates reversely, and the sliding frame 340 moves upward to its original position. Then, the connection box 320 can be continuously moved through the transmission mechanism 310. The first connection gear 322 can squeeze the driving gear 143 at its top, so that the top rotating frame 144 rotates around the fixed shaft 145. In this way, the first connection gear 322 can smoothly pass through the bottom of the driving gear 143;

[0075] The rotating frame 144 on the second driving mechanism 210 is arranged corresponding to the second connection gear 342 on the rising sliding frame 340, and only a set of rotating frame 144, driving motor 148, fixed shaft 145, etc. are arranged on the second driving mechanism 210. When the connection box 320 moves beside the second driving mechanism 210, the bottom of the second connection gear 342 can be meshed with the driving gear 143 on the second driving mechanism 210. Thus, the driving gear 143 on the second driving mechanism 210 is driven to rotate by the driving motor 148 on the second driving mechanism 210, so that the second connection gear 342 rotates, and the two clamping plates 350 move towards each other to clamp the battery pack.

Two transmission wheels 315 are respectively sleeved on the side surfaces of the two transmission shafts 314. The transmission belt 316 is drivingly connected between the two transmission wheels 315. The toothed belt 317 is arranged at the bottom of the transmission belt 316. Both first support frames 312 are fixedly connected to the top surface of the connection frame 311.

Both second support frames 313 are fixedly connected to the top surface of the connection frame 311. Both bottom ends of the second support frames 313 are fixedly connected to the top surfaces of the two fixing frames 120. The second conveyor 200 can support the connection frame 311 through the first support frames 312. The fixing frame 120 can support the connection frame 311 through the second support frames 313. The power box 319 is fixedly connected to the top of the connection frame 311. The power motor 318 is fixedly connected inside the power box 319. The power box 319 can shield the power motor 318. The output end of the power motor 318 is drivingly connected to the top end of one transmission shaft 314.

[0079] During specific implementation, the power motor 318 can drive one transmission shaft 314 to rotate. One transmission shaft 314 can drive the transmission wheel 315 to rotate, thereby causing the transmission belt 316 to move. The transmission belt 316 can drive the toothed belt 317 to move. The connection mechanism 330 can be driven to move through the toothed belt 317, so that a plurality of connection boxes 320 move cyclically along the bottom of the connection frame 311.

[0080] As Figures 10-11 shown, in this embodiment, the connection mechanism 330 includes a fixed seat 332, a sliding seat 334, two toothed blocks 337, a connection seat 331, an abutting seat 333, a positioning lead screw 335, a round block 336, and a plurality of round rods 338;

[0081] The fixed seat 332 is slidably connected to the top surface of the connection box 320. The sliding seat 334 is fixedly connected to the top surface of the fixed seat 332. The sliding seat 334 is slidably connected to the inner side surface of the connection frame 311. Both of the two cogs 337 are fixedly connected to the inner side surface of the sliding seat 334. Both of the two cogs 337 are engaged with the cog belt 317. The cog belt 317 passes through the inside of the sliding seat 334 and passes between two adjacent cogs 337. The connection seat 331 is slidably connected to the inner side surface of the fixed seat 332. The connection seat 331 can slide within the fixed seat 332. The bottom surface of the connection seat 331 is fixedly connected to the top surface of the connection box 320. The abutting seat 333 is slidably connected to the inner side surface of the connection seat 331. The positioning screw rod 335 passes through the inside of the abutting seat 333 and is screwed and connected to the inner side surface of the connection seat 331. The positioning screw rod 335 connects the abutting seat 333 to the connection seat 331. In this way, the abutting seat 333 and the connection seat 331 can be connected to the connection frame 311. The round block 336 is rotatably connected to the side surface of the connection seat 331. The side surface of the round block 336 contacts the side surface of the connection frame 311. A plurality of round rods 338 are all rotatably connected to the inner side surface at the top of the abutting seat 333. The bottom of the side surface of the round rod 338 contacts the top surface of the connection frame 311.

[0082] During specific implementation, when the transmission belt 316 drives the cog belt 317 to move, the cog belt 317 can drive the cogs 337 to move, so that the sliding seat 334 and the fixed seat 332 move. After the inner wall of the fixed seat 332 contacts the side surface of the connection seat 331, the fixed seat 332 can push the connection seat 331 to move, and further make the connection box 320 move along the bottom of the transmission mechanism 310. The connection boxes 320 can be grouped in pairs. Through a group of two connection boxes 320, two battery packs can be transported to the top of the battery housing, and then the two battery packs are placed in the battery housing at the same time. When lowering the battery pack, the battery pack can move downward between the guide frame one 131 and the guide frame two 132. The guide frame one 131 and the guide frame two 132 guide the battery pack, so that the connection seat 331 moves within the fixed seat 332, which is beneficial to accurately place the battery pack in the battery housing. When placing battery packs of different sizes and the distance between the two battery packs is small, the positioning screw rod 335 can be screwed out of the connection seat 331, and then the sliding seat 334 and the connection seat 331 are moved downward, so that the cogs 337 move downward relative to the cog belt 317. After the cogs 337 are disengaged from the cog belt 317, the position of the connection seat 331 can be adjusted, thereby adjusting the distance between a group of two connection boxes 320. Then the connection seat 331 and the sliding seat 334 are moved upward, so that the cogs 337 are inserted into the cog belt 317 again. Then the positioning screw rod 335 is screwed into the connection seat 331 again to connect the connection seat 331 and the abutting seat 333. In this way, the placement distance between adjacent two battery packs can be adjusted as needed.
