[0002] The charger utilizes high-frequency power supply technology and advanced intelligent dynamic adjustment charging technology. It employs a three-stage intelligent charging method: constant current, constant voltage, and low constant current. It features high charging efficiency, simple operation, light weight, and small size. The charger uses a microprocessor as its processing and control center, embedding complex hardware analog circuitry into the microprocessor to control the UPS operation via software programs. Therefore, its size and weight are significantly reduced, manufacturing costs are low, and the selling price is relatively low.

[0003] In the existing technology, the charger and the energy storage device are fixedly installed by bolts, screws and other connecting parts. After the energy storage device is fully charged, it is not easy to disassemble and replace it. The charger can only start charging again after the energy storage device has been discharged. The utilization efficiency is low. Moreover, the charger that is fixedly installed by bolts, screws and other connecting parts cannot prevent disassembly and damage by non-workers.

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Figures 1-7 In one embodiment of this utility model, a charger for easy replacement of an energy storage device includes a charger 1 and an energy storage device 2 located inside the charger 1. The charger 1 has a base 3, and a mounting base 4 is located above the base 3. The energy storage device 2 is located inside the mounting base 4. A telescopic mechanism 6 for adjusting the position of the mounting base 4 is provided between the base 3 and the mounting base 4. A lifting mechanism 5 for adjusting the positions of the base 3 and the mounting base 4 is provided below the base 3. The lifting mechanism 5 includes two sets of cross-distributed brackets 501, with sliders 502 rotatably mounted at both ends of each set of brackets 501. The brackets 501 are slidably connected to the charger 1 and the base 3 respectively via the two sets of sliders 502. The telescopic mechanism 6 includes two sets of first telescopic frames 601 slidably mounted inside the base 3, and a second telescopic frame 602 slidably mounted to the first telescopic frames 601. The mounting base 4 is fixedly connected to the second telescopic frame 602. The base 3 has two sets of symmetrically distributed... The fabric has a threaded rod 603, and threaded tubes 604 are rotatably installed inside both sets of first telescopic frames 601. The base 3 is provided with a locking mechanism 7 for fixing the card seat 4. A card block 701 is fixedly installed below the card seat 4. The card seat 4 is movably engaged with the base 3 through the card block 701. The locking mechanism 7 includes two sets of symmetrically distributed card rods 702. The two sets of card rods 702 are movably engaged with the card block 701 respectively. The position of the card seat 4 can be adjusted by the lifting mechanism 5 and the telescopic mechanism 6, which makes it convenient for staff to remove and replace the energy storage device 2 fixed inside the charger 1. After one energy storage device 2 is charged, the next energy storage device 2 can be charged, which improves the working efficiency of the charger 1. In addition, the card seat 4 and the base 3 in the charger 1 are fixedly connected by the locking mechanism 7, which completes the anti-theft protection of the charger 1 and the internal energy storage device 2, and avoids economic losses caused by unauthorized personnel disassembling the energy storage device 2.

[0029] In this embodiment, reference Figure 2 , Figure 3As shown, both the base 3 and the elevator are equipped with two sets of symmetrically distributed bidirectional lead screws 503. The two ends of the bidirectional lead screws 503 pass through the base 3 or the elevator and are rotatably connected to the base 3 or the elevator. The bidirectional lead screws 503 pass through two sets of corresponding sliders 502 and are threadedly connected to the two sets of sliders 502. The left end of each set of bidirectional lead screws 503 is sleeved with a synchronous pulley 504. Both the base 3 and the elevator are equipped with a synchronous belt 505, and the synchronous belt 505 is connected to the two sets of corresponding synchronous pulleys 504. After the energy storage device 2 in the charger 1 is fully charged, the motor in the base 3 and the charger 1 is started to drive the bidirectional lead screws 503 to rotate. Under the limiting action of the base 3 and the charger 1, the two sets of sliders 502 slide relative to each other or towards each other, changing the height of the two sets of supports 501. This causes the base 3 to move the upper card seat 4 and the energy storage device 2 downward, and the connection between the energy storage device 2 and the charger 1 is separated.

[0030] In this embodiment, reference Figure 4 and Figure 5 As shown, each of the two sets of threaded rods 603 has a transmission wheel 607 sleeved on its left end. A transmission belt 608 is provided inside the base 3, and the transmission belt 608 is connected to the two sets of transmission wheels 607 respectively. The right ends of the two sets of threaded rods 603 pass through the corresponding first telescopic frame 601 and are threadedly connected to the first telescopic frame 601. A threaded tube 604 passes through the second telescopic frame 602 and is threadedly connected to the second telescopic frame 602. Two sets of symmetrically distributed limiting grooves 605 are provided on the threaded rods 603, and two sets of symmetrically distributed limiting blocks 606 are provided inside the threaded tube 604, with the limiting blocks 606 corresponding to the limiting grooves 605. The threaded tube 604 is slidably connected to the threaded rod 603 via a limiting block 606. The motor inside the base 3 is started to drive the threaded rod 603 to rotate. Under the limiting action of the base 3, the two sets of first telescopic frames 601 slide within the base 3. Under the action of the limiting block 606 and the limiting groove 605, the threaded tube 604 inside the first telescopic frame 601 rotates synchronously with the threaded rod 603. Under the limiting action of the first telescopic frame 601, the second telescopic frame 602 drives the card seat 4 and the energy storage device 2 above the card seat 4 to slide out from the charger 1, thus completing the convenient retrieval of the energy storage device 2.

[0031] In this embodiment, reference Figure 6 , Figure 7As shown, each of the two sets of locking rods 702 is fitted with a first spring 703, and each of the two sets of locking rods 702 is fitted with a stop block 704. The two sets of locking rods 702 are slidably connected to the base 3 via the stop blocks 704. The two ends of the first spring 703 are fixedly connected to the base 3 and the stop block 704, respectively. Each of the two sets of locking rods 702 is fixedly mounted with a rack 705. The base 3 has a mounting block 709, and the mounting block 709 has a lock cylinder 706. The lock cylinder 706 passes through the base 3 and is rotatably connected to both the base 3 and the mounting block 709. A gear 707 is fitted onto the lock cylinder 706, and the gear 707 meshes with the two sets of racks 705. A torsion spring 708 is fitted onto the lock cylinder 706, and the two ends of the torsion spring 708 are fixedly connected to the lock cylinder 706 and the base 3, respectively. The mounting block 709 has multiple sets of equidistantly distributed first locking blocks 711 and second springs 710. The multiple sets of first locking blocks 711 are all... The mounting block 709 is slidably connected, and the lock cylinder 706 has multiple sets of equidistantly distributed second locking blocks 712. The two ends of the second spring 710 are fixedly connected to the first locking block 711 and the mounting block 709, respectively. The second locking blocks 712 are slidably connected to the lock cylinder 706, and the second locking blocks 712 are correspondingly set with the first locking blocks 711. When the correct key is inserted into the slot of the lock cylinder 706 in the mounting block 709, the key insertion pushes the multiple sets of second locking blocks 712 downward. The sliding of the second locking blocks 712 causes the first locking blocks 711 to slide downward until the upper end of the first locking block 711 and the lower end of the second locking blocks 712 are flush with the connecting surfaces of the lock cylinder 706 and the mounting block 709. Then, the lock cylinder 706 is rotated to drive the gear 707 to rotate. The gear 707 pushes the rack 705 to both sides. The two sets of racks 705 drive the two sets of latches 702 to slide to both sides simultaneously, releasing the base 3 from locking the latch 701.

[0032] In this embodiment, after the energy storage device 2 in the charger 1 has finished charging, the base 3 and the motor in the charger 1 are activated to drive the rotation of the bidirectional lead screw 503. Under the limiting action of the base 3 and the charger 1, the two sets of sliders 502 slide relative to or towards each other, changing the height of the two sets of supports 501. This causes the base 3 to move the upper card seat 4 and the energy storage device 2 downwards, separating the connection between the energy storage device 2 and the charger 1. The correct key is then inserted into the lock cylinder 706 slot of the mounting block 709. The insertion of the key pushes multiple sets of second lock blocks 712 downwards. The sliding of the second lock blocks 712 respectively causes the first lock blocks 711 to slide downwards until the upper end of the first lock block 711 and the lower end of the second lock block 712 are connected to the lock cylinder 706 and the mounting block 709. The connecting surfaces are flush. Then, the lock cylinder 706 is rotated to drive the gear 707 to rotate. The gear 707 pushes the rack 705 to both sides. The two sets of racks 705 drive the two sets of locking rods 702 to slide synchronously to both sides, releasing the base 3 from locking the locking block 701. The motor in the base 3 is started to drive the threaded rod 603 to rotate. Under the limiting action of the base 3, the two sets of first telescopic frames 601 slide in the base 3. Under the action of the limiting block 606 and the limiting groove 605, the threaded tube 604 in the first telescopic frame 601 rotates synchronously with the threaded rod 603. Under the limiting action of the first telescopic frame 601, the second telescopic frame 602 drives the card seat 4 and the energy storage device 2 above the card seat 4 to slide out from the charger 1, completing the convenient removal of the energy storage device 2.
