Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology for transportation, and in particular to a mechanism for assisting in the insertion and removal of batteries in a transfer vehicle. Background Technology

[0002] Battery swapping for new energy vehicles is a necessary situation that new energy vehicles need to face after long-term use. When the battery capacity of a new energy vehicle decreases to less than 70% of its initial capacity, and it is not due to human-caused quality problems, the new energy vehicle can go to a battery swapping station for battery maintenance or replacement, thereby maintaining the lifespan of the new energy vehicle and increasing its value, allowing the vehicle's range to be restored to near the level of a new car.

[0003] With the surge in the number of new energy vehicles, the number of vehicles choosing battery swapping services is also increasing, bringing new challenges to the operation of battery swapping stations. In the future, we may see queues at some battery swapping stations, primarily due to the instantaneous imbalance between supply and demand between different stations. Therefore, our company has designed a containerized cellular energy storage cabinet. However, existing containerized cellular energy storage cabinets require rapid insertion and removal of battery assemblies. Therefore, in response to these challenges, there is an urgent need to develop a transfer vehicle to assist in battery insertion and removal mechanisms to meet practical application needs.

[0016] For this embodiment, please refer to Figures 1-4 The specific implementation of this transfer vehicle-assisted battery insertion and removal mechanism includes a cabinet 1 and a carrier box 2 for storing and transporting the cabinet 1. The top surface of the carrier box 2 and its two side walls form an "L"-shaped side wall structure 3. The L-shaped side wall structure is hinged and flipped at the middle of the top surface of the carrier box 2. The top surface of the cabinet 1 is provided with a cable reel 6, and the inside of the cable reel 6 is provided with a wound steel cable 7. The corner of the "L"-shaped side wall structure 3 is provided with a rotatable guide wheel 14. Structure 3 has a rotatable guide sleeve 15 near the inner wall of cabinet 1. The guide sleeve 15 is a cylindrical hollow structure. One end of the steel cable 7 extends around the guide wheel 14 to the outside of one end of the guide sleeve 15. The end of the steel cable 7 near the end away from the winding frame 6 is provided with a buckle 8. The top surface of the carrying box 2 is provided with a telescopic cylinder 5. The telescopic end of the telescopic cylinder 5 is rotatably connected to the top surface of the "L"-shaped side wall structure 3. The end of the telescopic cylinder 5 away from the telescopic end is rotatably connected to the top surface of the carrying box 2.

[0017] Specifically, such as Figure 3-4 As shown, by setting a cable reel 6, a guide wheel 14 and a guide sleeve 15 for adjusting the horizontal extension position of the steel cable 7 inside the carrier box 2, the steel cable 7 can extend to the side of the cabinet 1 near the storage port 4, and the battery handle 10 can be fixed and pulled out by the latch 8. This structure can form the main rigid structure of the "mechanical arm" through the "L"-shaped side wall structure 3 on both sides of the carrier box 2, integrating the existing battery pulling structure into the carrier box 2. Its structure is simple and convenient, which is conducive to the transfer vehicle pulling out the battery at the carrier box 2.

[0018] Specifically, such as Figure 2 As shown, a number of storage slots 4 are provided on one side of the cabinet 1. The storage slots 4 are arranged in a linear array. A rotatable latch 8 is provided on one side of the storage slot 4. One end of the latch 8 can swing to the front of the storage slot 4.

[0019] Specifically, such as Figure 3As shown, the top surface of the cabinet 1, the corner of the "L"-shaped side wall structure 3, and the side wall of the "L"-shaped side wall structure 3 are respectively provided with a first guide rail 11, a second guide rail 12, and a third guide rail 13.

The cable reel 6 is slidably set on the top of the cabinet 1 via the first guide rail 11. The guide wheel 14 is slidably set on the corner of the "L"-shaped side wall structure 3 via the second guide rail 12. The guide sleeve 15 is movably connected to the third guide rail 13 via the steering knuckle 16. The guide sleeve 15 is slidably set on the side wall of the "L"-shaped side wall structure 3 via the third guide rail 13.

[0020] When the battery needs to be removed from different storage slots 4 in the carrier box 2, the positions of the winding rack 6, guide wheel 14 and guide sleeve 15 can be moved by the first guide rail 11, the second guide rail 12 and the third guide rail 13 respectively, so that the winding rack 6, guide wheel 14 and guide sleeve 15 are moved to the same plane as the storage slot 4, so as to keep the battery stable when it is held.

[0021] The working process of a transfer vehicle assisting in battery insertion and removal mechanism: The "L"-shaped side wall structure 3 of the carrier box 2 near the storage port 4 of the cabinet 1 is lifted by rotating the telescopic cylinder 5; Next, swing the steering knuckle 16 to the vertical position of the guide sleeve 15, and move the positions of the winding frame 6, guide wheel 14 and guide sleeve 15 through the first guide rail 11, the second guide rail 12 and the third guide rail 13 respectively, and pull the lock 8 to fasten and fix the battery handle 10. Finally, the winding frame 6 is driven by a motor or other internal or external drive components to retract the steel cable 7. The steel cable 7 can then pull out the battery stored in the socket 4 along the guide sleeve 15 and guide wheel 14.
