Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, specifically a pull-out battery maintenance device for household energy storage equipment. Background Technology

[0002] Currently, there are risks associated with operating batteries while they are energized during energy storage device maintenance. Furthermore, the complexity of battery maintenance procedures leads to issues such as susceptibility to errors and low maintenance efficiency.

[0003] During the battery maintenance of some energy storage devices, cranes or forklifts are required, but they cannot be finely adjusted in a confined space and are prone to collision damage.

[0004] Therefore, it is necessary to design a pull-out battery maintenance device for home energy storage devices to provide dual safety protection and improve the convenience of battery maintenance operations. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pull-out battery maintenance device for household energy storage devices, which provides dual safety protection and improves the convenience of battery maintenance operations.

[0006] To achieve the above objectives, this utility model provides a pull-out battery maintenance device for household energy storage equipment, comprising a pushing mechanism, a battery pack, a battery housing, and a handle. The pushing mechanism is installed at the rear of the battery pack, which is slidably connected to the battery housing. The pushing mechanism includes a mechanical lock, a connecting piece, an indicator plate, a front gear cover, a rear gear cover, a limit switch, a rotary pushing shaft, a buckle, a driving gear, a driven gear, an indicator gear, a lock hole baffle, and a micro switch. A mechanical lock is installed on the upper end of the front gear cover. The upper end of the connecting piece is connected to a connecting block on the side of the mechanical lock. A connecting rod is located on the lower front side of the connecting piece. The connecting rod passes through one end of the lock hole baffle and the front gear cover, and then contacts the drive rod of the micro switch. The other end of the lock hole baffle covers the lock hole of the rear gear cover. Alternatively, the lock hole of the rear gear cover can be exposed. A driving gear, a driven gear, and an indicator gear are installed between the front gear cover and the rear gear cover. The center of the driving gear corresponds to the position of the lock hole of the rear gear cover. The front end of the driving gear is connected to the rotating drive shaft. The driving gear meshes with the driven gear, and the driven gear meshes with the indicator gear. The shaft of the indicator gear is connected to the center of the indicator plate. The indicator plate is located on the rear surface of the rear gear cover. A buckle is installed on each side of the rotating drive shaft. The rotating drive shaft, the buckles, and the connecting parts of the battery box are connected or separated. A limit switch is installed above the rotating drive shaft. The interlocking piece of the limit switch contacts or separates from the protrusion on the front surface of the indicator gear. When the lock hole of the rear gear cover is exposed, the end of the handle is connected to the center of the driving gear.

[0007] The battery pack contains batteries, and two baffles are installed at the rear of the battery pack. A push mechanism is installed between the two baffles, and the end of the handle passes through the through hole of the baffle and is connected to the center of the drive gear of the push mechanism.

[0008] The battery pack is provided with a sliding block and a stop block. The bottom surface of the battery box is provided with a slide rail, a rubber buffer pad, a base, and a snap-fit ​​seat. The sliding block is slidably connected to the slide rail, and the stop block is positioned corresponding to the rubber buffer pad.

[0009] When the battery pack slides to its limit position, the stop block is embedded in the rubber buffer pad, the rotating drive shaft of the push mechanism engages with the base, and the buckle of the push mechanism is inserted into the snap-fit ​​seat.

[0010] The rotary drive shaft is mounted on a fixed plate on the front side of the front gear cover.

[0011] When the interlocking plate contacts the protrusion on the front surface of the indicator gear, the limiting screw on the interlocking plate locks the indicator gear, and the spring clip installed on the top surface of the rear gear cover plate is embedded in the groove on the surface of the indicator gear.

[0012] The micro switch and limit switch are connected in series in the main circuit of the energy storage device.

[0013] The sign has a two-color area on its surface.

[0014] Compared with existing technologies, this utility model features a dual safety interlock structure combining a mechanical lock with a micro switch and a handle with a limit switch, preventing safety hazards caused by power being supplied when the battery pack is not in its proper position. An indicator shows the connection status, reducing the error rate by ≥90%. The pull-out structure shortens the maintenance time for home energy storage devices to within 3 minutes, improving maintenance efficiency. Attached Figure Description

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] See Figure 1 This utility model is a pull-out battery maintenance device for household energy storage equipment, including a pushing mechanism, a battery pack, a battery box, and a handle. The pushing mechanism 1 is installed at the rear of the battery pack 2, and the battery pack 2 is slidably connected to the battery box 3.

[0027] See Figure 2 The battery pack 2 contains a battery 23. Two baffles 24 are installed at the rear of the battery pack 2. The push mechanism 1 is installed between the two baffles 24. The end of the handle 4 passes through the through hole of the baffle 24 and is connected to the rotating push shaft 16 of the push mechanism 1.

[0028] The battery pack 2 is equipped with a sliding block 21 and a stop block 22. The bottom surface of the battery housing 3 is equipped with a slide rail 31 and a rubber buffer pad 32. The sliding block 21 is slidably connected to the slide rail 31 to realize the sliding of the battery pack 2. The stop block 22 corresponds to the position of the rubber buffer pad 32. When the battery pack 2 slides to the limit position, the stop block 22 is embedded in the rubber buffer pad 32 to prevent impact damage caused by misoperation. The rotational push shaft 16 of the push mechanism 1 engages with the base 33, and the buckle 17 of the push mechanism 1 is inserted into the locking seat 34 to lock the battery pack 2 and the battery housing 3.

[0029] See Figure 3 , Figure 4The driving mechanism 1 includes a mechanical lock 11, a connecting piece 12, an indicator plate 13, a front gear cover plate 14, a rear gear cover plate 18, a limit switch 15, a rotary drive shaft 16, a latch 17, a driving gear 19, a driven gear 110, an indicator gear 111, a lock hole baffle 112, and a micro switch 113. The mechanical lock 11 is mounted on the upper end of the front gear cover plate 14. The upper end of the connecting piece 12 is connected to the connecting block on the side of the mechanical lock 11. The lower part of the connecting piece 12 is front... The side has a connecting rod that passes through one end of the lock hole baffle 112 and the front gear cover plate 14, and then contacts the drive rod of the micro switch 113. The other end of the lock hole baffle 112 either covers or exposes the lock hole of the rear gear cover plate 18. A driving gear 19, a driven gear 110, and an indicator gear 111 are installed between the front gear cover plate 14 and the rear gear cover plate 18. The center of the driving gear 19 corresponds to the position of the lock hole of the rear gear cover plate 18. Figure 5 As shown, the front end of the drive gear 19 is connected to the rotary drive shaft 16. The drive gear 19 meshes with the driven gear 110, and the driven gear 110 meshes with the indicator gear 111. The shaft of the indicator gear 111 is connected to the center of the indicator plate 13. The indicator plate 13 is located on the rear surface of the rear gear cover 18. A buckle 17 is installed on each side of the rotary drive shaft 16. The rotary drive shaft 16, the buckle 17 and the connecting parts of the battery box 3 are connected or separated. A limit switch 15 is installed above the rotary drive shaft 16. The interlocking piece 151 of the limit switch 15 contacts or separates from the protrusion on the front surface of the indicator gear 111. When the lock hole of the rear gear cover 18 is exposed, the end of the handle 4 is connected to the center of the drive gear 19.

[0030] Microswitch 113 and limit switch 15 are connected in series in the main circuit of the energy storage device. The main circuit will only resume power supply when both microswitch 113 and limit switch 15 are triggered. Limit switch 15 serves as a secondary confirmation of the power-off state. Before the battery pack 2 is fully returned to its original position, limit switch 15 prevents the main circuit from being powered on, thus preventing safety hazards caused by power being supplied when the battery pack 2 is not in its original position.

[0031] The indicator 13 has a two-color area on its surface, which uses different colors, such as red and green, to indicate whether the battery pack is in a "disconnected" or "connected" state, intuitively reflecting the status of the home energy storage device.

[0032] See Figure 6The mechanical lock 11 is in the unlocked state, the connecting piece 12 is in the raised state, the micro switch 113 is not triggered, the main relay of the main circuit cannot close, and the lock hole baffle 112 exposes the lock hole of the rear gear cover plate 18. The battery pack 2 is placed in the slide rail 31. When the battery pack 2 is pushed to the bottom and a "click" is heard, the rotating push shaft 16 connects with the base 33. The end of the handle 4 is inserted into the drive gear 19. Rotating the handle 4 clockwise drives the drive gear 19 and the rotating push shaft 16 to rotate. The rotating push shaft 16 meshes with the base 33, thereby pushing the battery pack 2 inward. Simultaneously, the drive gear 19 drives the indicator gear 111 to rotate through the driven gear 110.

[0033] like Figure 7 As shown, as the indicator gear 111 rotates, the protrusion of the indicator gear 111 contacts the interlocking piece 151, triggering the limit switch 15. Figure 8 As shown, the limiting screw 152 locks the indicator gear 111, and the spring clip 153 is embedded in the groove on the surface of the indicator gear 111, achieving double limiting. At this time, the "connection" on the surface of the indicator plate 13 is exposed from the window of the baffle 24.

[0034] Next, remove handle 4 from the drive gear 19, insert the key into the mechanical lock 11 and rotate it clockwise. This causes the connecting piece 12 to fall and lock the battery pack 2. The hole stop plate 112 moves to the right, covering the lock hole of the rear gear cover plate 18, preventing handle 4 from being inserted again. Figure 9 As shown. At the same time, the connecting rod on the lower front side of the connecting piece 12 presses down the driving rod of the micro switch 113, triggering the micro switch 113 and restoring power supply to the main circuit.

[0035] See Figure 10 When it is necessary to remove battery pack 2, the key is inserted into mechanical lock 11 and rotated counterclockwise to the designated position. Connecting plate 12 lifts up and unlocks battery pack 2. Simultaneously, the force applied by the connecting rod to the drive rod of micro switch 113 decreases, micro switch 113 is not triggered, and the main relay of the main circuit is disconnected. Lock hole baffle 112 moves to the left, exposing the lock hole of rear gear cover 18. When the key is not rotated to the unlock position, the lower part of connecting plate 12 remains locked to battery pack 2, the lock hole of rear gear cover 18 is not fully exposed, the handle 4 cannot be inserted, and battery pack 2 cannot be shaken out, ensuring that battery pack 2 cannot be pulled out when the main circuit is not de-energized.

[0036] Insert the end of the handle 4 into the drive gear 19, and shake the handle 4 counterclockwise to drive the drive gear 19 and the rotating push shaft 16 to rotate. The rotating push shaft 16 meshes with the base 33, thereby pushing the battery pack 2 to move outward. At the same time, the drive gear 19 drives the indicator gear 111 to rotate through the driven gear 110.

[0037] As the indicator gear 111 rotates, the protrusion on the indicator gear 111 separates from the interlocking piece 151, and the limit switch 15 is not triggered. At this time, the "separation" mark on the surface of the indicator plate 13 is exposed through the window of the baffle 24, as shown. Figure 6 As shown.

[0038] This invention features a dual safety interlock structure, combining a mechanical lock with a micro switch and a handle with a limit switch, to prevent safety hazards caused by power being applied when the battery pack is not in its proper position. An indicator shows the connection status, reducing the error rate by ≥90%. The pull-out structure shortens the maintenance time for home energy storage devices to within 3 minutes, improving maintenance efficiency. This invention is suitable for energy storage devices requiring safe and efficient battery maintenance.
