[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A battery pack replacement device for new energy vehicles includes a mounting plate 1 and a fixing frame 3. An electric rotating seat 2 is mounted at the top center of the mounting plate 1, and the fixing frame 3 is fixedly connected to the top of the electric rotating seat 2. A fixing seat 9 is provided below the fixing frame 3, and the bottom two ends of the fixing seat 9 are provided with picking and placing components for gripping and placing new energy battery packs. The picking and placing components include a first electric telescopic rod 10, a moving groove 11, a moving block 12, and an L-shaped clamping plate 13. The first electric telescopic rod 10 is fixedly installed on both sides of the fixing seat 9. The bottom two ends of the fixing seat 9 have moving grooves 11 at their centers. The output end of the first electric telescopic rod 10, which passes through the moving groove 11, is equipped with a moving block 12. The moving block 12 is slidably connected in the moving groove 11, and the bottom of the moving block 12 is fixedly installed with an L-shaped clamping plate 13.

[0027] This utility model, through the coordinated use of the above-mentioned pick-and-place components, facilitates the picking and placing of new energy battery packs, thereby improving their efficiency.

[0028] By activating the first electric telescopic rod 10, its output end drives the moving block 12 to move left and right within the moving slot 11 for adjustment, so that the moving block 12 with the L-shaped clamping plate 13 can grip and clamp new energy battery packs of different sizes. After gripping and clamping, the lifting cylinder 7 is raised, and then the electric rotating seat 2 is activated, so that its rotating end drives the fixing frame 3 to rotate to the area where the battery pack is placed and then locks it.

[0029] The bottom end of the L-shaped clamping plate 13 is provided with a support assembly for supporting the battery pack during gripping. The support assembly includes a second electric telescopic rod 19, a mounting base 20, a third electric telescopic rod 21, a locking rod 22, a support plate 23, and an anti-slip pad 24. The second electric telescopic rod 19 is fixedly installed at the bottom end of the L-shaped clamping plate 13, and the second electric telescopic rod 19 is arranged in two symmetrical sets. The output end of the second electric telescopic rod 19 is fixed with the mounting base 20. The third electric telescopic rod 21 is installed at both ends of the outer side of the mounting base 20. The output end of the third electric telescopic rod 21, which extends through the mounting base 20, is fixed with a locking rod 22. The outside of the locking rod 22 is provided with a support plate 23. The inside of the support plate 23 is provided with sleeve interfaces, and the locking rod 22 is sleeved inside the sleeve interfaces. The top of the support plate 23 is provided with an anti-slip pad 24.

[0030] This utility model utilizes components such as a second electric telescopic rod 19, a mounting base 20, a third electric telescopic rod 21, a clamping rod 22, a support plate 23, and an anti-slip pad 24 to improve the stability of the L-shaped clamping plate 13 when gripping the new energy battery pack, thereby increasing the efficiency of placing the gripped new energy battery pack. It also improves the efficiency of battery pack replacement. Furthermore, the anti-slip pad 24 helps to prevent slippage when the new energy battery pack is gripped and held.

[0031] Furthermore, after the L-shaped clamping plate 13 clamps and fixes the new energy battery pack, the second electric telescopic rod 19 is activated to drive the mounting base 20 to descend so that the support plate 23 is lowered below the bottom of the battery pack. At this time, the third electric telescopic rod 21 is activated so that its output end drives the support plate 23 to move to the bottom of the battery pack. Then, by controlling the second electric telescopic rod 19, the support plate 23 is raised so that it contacts the bottom of the battery pack and locks.

[0032] The top end of the fixed frame 3 has a slot, and the front and back sides of the slot have first sliding grooves 4. A dual-axis cylinder 5 is installed inside the slot, and a slide block 6 is installed at the output end of the dual-axis cylinder 5. The slide block 6 is slidably connected to the first sliding groove 4. A lifting cylinder 7 is fixedly installed on the top of the slide block 6, and a connecting seat 8 is fixedly installed at one end of the lifting cylinder 7 that passes through the fixed frame 3. A fixed seat 9 is fixedly installed at the bottom of the connecting seat 8.

[0033] By using components such as slots, first sliding grooves 4, dual-axis cylinders 5, and sliding blocks 6 in combination, the picking and placing assembly can easily move the new energy battery pack closer to the placement area after it has picked it up.

[0034] By activating the dual-axis cylinder 5, its output end drives the slide block 6 to move left and right inside the first slide groove 4, so that the grabbed battery pack can be quickly moved from the placement area to the placement position. At this time, the lifting cylinder 7 drives the fixed seat 9 to descend, so that the battery pack on the fixed seat 9 contacts the placement position.

[0035] Slider 14 is fixedly installed at both ends of the top of the L-shaped clamping plate 13, and the slider 14 is slidably connected to the corresponding second slide groove 15 on the bottom of the fixed base 9. The second slide groove 15 and the slider 14 are adapted to each other. By setting the slider 14 and the second slide groove 15, the stability of the L-shaped clamping plate 13 when moving to clamp the new energy battery pack is improved.

[0036] The L-shaped clamping plate 13 has slots 16 around its inner perimeter, and a locking block 17 is engaged inside the slots 16. The slots 16 and the locking block 17 are compatible, and a rubber protective pad 18 is fixedly connected to one end of the locking block 17. By setting up components such as the slots 16, the locking block 17, and the rubber protective pad 18, the L-shaped clamping plate 13 can effectively protect the new energy battery pack when clamping and gripping it.

[0037] In practical use, firstly, start the lifting cylinder 7, so that its output end drives the fixed seat 9 to descend and approach the new energy battery pack through the connecting seat 8. Then, start the first electric telescopic rod 10, so that its output end drives the moving block 12 to move left and right in the moving slot 11 for adjustment, so that the moving block 12 with the L-shaped clamping plate 13 can grasp and clamp new energy battery packs of different sizes. After grasping and clamping.

[0038] After the L-shaped clamping plate 13 clamps and fixes the new energy battery pack, the second electric telescopic rod 19 is activated to drive the mounting base 20 to descend so that the support plate 23 is lowered below the bottom of the battery pack. At this time, the third electric telescopic rod 21 is activated so that its output end drives the support plate 23 to move to the bottom of the battery pack. Then, by controlling the second electric telescopic rod 19, the support plate 23 is raised so that it contacts the bottom of the battery pack and locks.

[0039] At this point, the lifting cylinder 7 is raised, and then the electric rotating seat 2 is activated, causing its rotating end to drive the fixing frame 3 to rotate to the area where the battery pack is placed and lock it. Then, the dual-axis cylinder 5 is activated, causing its output end to drive the slide 6 to move left and right inside the first slide groove 4, so that the grabbed battery pack can be quickly moved above the placement position. At the same time, the lifting cylinder 7 drives the fixing seat 9 to descend, so that the battery pack on the fixing seat 9 contacts the placement position. At the same time, the first electric telescopic rod 10 retracts back to its original position, and the third electric telescopic rod 21 and the second electric telescopic rod 19 also retract back to their original positions, thereby lowering the new energy battery pack.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
