Description

Technical Field

[0001] This invention relates to the field of lithium battery energy storage technology, specifically to an energy storage device. Background Technology

[0002] With the rapid development of electric vehicles, addressing their safety issues has become a new topic and challenge for the automotive industry. Currently, lithium-ion batteries are the primary power source for electric vehicles, making their safety a major public concern. Lithium-ion batteries offer advantages such as high energy density, light weight, and long lifespan.

[0003] Generally, before a new energy electric vehicle's battery leaves the factory and is not used, the lithium battery supplier performs charging and discharging cycles to ensure the battery's normal operation. Charging time is typically 5-6 hours to fully charge the battery. When the battery is nearly depleted, a longer charge is performed, lasting 8-9 or even 10 hours, to allow the battery's chemical reaction to complete a full cycle. Current lithium battery production processes require the use of energy storage devices to charge the lithium batteries.

[0004] However, existing energy storage devices can only charge a single battery and cannot charge lithium batteries of different sizes. Furthermore, it is inconvenient to remove the lithium batteries after charging, which reduces working efficiency. Therefore, they do not meet the current needs.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention, by providing a placement slot, a clamping mechanism, and a transmission mechanism A, places a lithium battery on top of a placement plate. Under the action of gravity, the placement plate moves downward, causing the rack to move downward, which in turn causes gear B to rotate, thereby causing the crossbar to rotate, which in turn causes bevel gear A to rotate, which in turn causes bevel gear B to rotate. The rotating rod rotates, and the two threaded blocks move towards each other simultaneously, causing the clamping plates to move towards each other, thus limiting the lithium battery. The electrode plates contact the lithium battery, charging the lithium battery. This invention can charge lithium batteries of different sizes.

[0018] 2. This invention, through the installation of a horizontal transmission device and transmission mechanism B, allows the push plate to be pressed downwards under the weight of the lithium battery when it is positioned above the storage plate. An external thread is provided on the upper surface of the pin shaft. The threaded tube moves downwards, causing the pin shaft to rotate in the opposite direction, which in turn drives gear C to rotate. The conveyor belt drives gear D to rotate, which in turn drives the vertical shaft to rotate, which in turn drives gear A to rotate. This causes the rack to move backwards, thus moving the drawer backwards and retracting it into the storage slot. When charging is complete and the lithium battery needs to be removed, simply pull the drawer forward out of the storage slot using the handle. The drawer moves forward, causing the strip plate and sawtooth A to move forward. Sawtooth A meshes with gear A, causing gear A to rotate in the opposite direction, which in turn drives the vertical shaft to rotate in the opposite direction, which in turn drives gear D to rotate. The conveyor belt drives gear C to rotate, which in turn drives the pin shaft to rotate. The threaded tube spirals upwards outside the pin shaft, causing the push plate to pass through the through slot A and push the lithium battery upwards, facilitating the removal of the lithium battery from the storage slot. This invention allows for the quick removal of fully charged lithium batteries, improving work efficiency. Attached Figure Description

A supercapacitor 8 is installed in the rear of the cabinet 1 through a cavity 7. Four storage slots 2 are evenly arranged on the front face of the cabinet 1. A strip groove 4 is provided on both sides of the inner wall of the storage slot 2. A groove 16 is provided on the inner wall of the strip groove 4.

An ejection mechanism 13 is movably arranged on both sides of the placement slot 10 through a transmission mechanism B15. Square slots 12 are provided on both sides in front of the upper end face of the storage slot 2. The transmission mechanism B15 moves inside the square slots 12.

[0029] The clamping mechanism 11 includes a storage plate 1104. The lower end face of the storage plate 1104 is connected to the upper end face of the movable groove 17 by four springs 1106. Clamping plates 1101 are provided at both the front and rear of the upper end face of the storage plate 1104. Electrode plates 1102 are installed on the opposite side of the outer surface of the two clamping plates 1101. Slide plates 1103 are provided on both sides of the outer surface of the clamping plates 1101. Through grooves A1105 are provided on both sides of the upper end face of the storage plate 1104.

A gear B1404 is sleeved in the middle of the outer surface of the crossbar 1403. Bevel gears A1402 are sleeved on both sides of the outer surface of the crossbar 1403, and gears B1404 mesh with the rack 1401 to improve the stability of the connection between the rack 1401 and the shelf 1104. The up and down movement of the rack 1401 can drive the gear B1404 to rotate, thereby driving the bevel gears A1402 to rotate.

[0030] Rotating rods 1407 are provided on both sides of the shelf 1104. Each rotating rod 1407 includes a short shaft, and threaded rods are installed on the front and rear ends of the short shaft.

The vertical plate is fixedly connected to the slide plate 1103. The lower end face of the slide plate 1103 is slidably connected to the insert plate 1107 through the slide groove. The lower end face of the insert plate 1107 is fixedly connected to the upper end face of the threaded block 1406, thereby improving the stability of the shelf 1104 moving up and down.

[0032] The horizontal transmission device 5 includes a strip plate 501. One side of the outer surface of the strip plate 501 is fixedly connected to the drawer 3. Multiple saw teeth A502 are evenly installed on the front of the other side of the outer surface of the strip plate 501. A gear A503 is provided on one side of the strip plate 501, and the gear A503 meshes with the saw teeth A502. When the strip plate 501 moves, the saw teeth A502 move, thereby driving the gear A503 to rotate. The transmission mechanism B15 includes a vertical shaft 1501. The outer surface of the vertical shaft 1501 is fixedly connected to the inner ring of the gear A503 by welding. A gear D1506 is sleeved below the outer surface of the vertical shaft 1501. A gear C1505 is provided on the opposite side of the two gears D1506. A conveyor belt 1507 is sleeved on the outer surface of the gears C1505 and D1506. Multiple saw teeth B1502 are evenly installed on the inner surface of the conveyor belt 1507, and the saw teeth B1502 mesh with the gears C1505 and D1506. The rotation of the gear A503 drives the vertical shaft 1501 to rotate, thereby driving the gear D1506 to rotate, and the conveyor belt 1507 conveys.

[0033] The inner ring of gear C1505 is fixedly connected to a pin 1503 by welding. The ejection mechanism 13 includes a threaded tube 1301. An external thread is provided on the upper surface of the outer surface of the pin 1503. The threaded tube 1301 is screwed into the external thread. The upper end face of the threaded tube 1301 is rotatably connected to a push plate 1302 through a bearing. A through groove B1504 is provided on the front of both sides of the lower end face of the drawer 3. The conveyor belt 1507 drives the pin 1503 to rotate. The threaded tube 1301 is screwed upward on the outer surface of the pin 1503, raising the height of the push plate 1302.

[0034] One electrode 1102 is electrically connected to the positive electrode of the supercapacitor 8, and the other electrode 1102 is electrically connected to the negative electrode of the supercapacitor 8. Horizontal grooves are provided on both the front and back of the upper surface of the placement plate 1104. A locking block is installed in the middle of the lower surface of the clamping plate 1101, and the locking block is inserted into the inside of the horizontal groove. When the lithium battery contacts the electrode 1102, the lithium battery can be charged, improving the stability of the clamping plate 1101 moving back and forth.

[0035] A cooling fan 6 is installed on the rear end face of the cabinet 1. The cooling fan 6 is connected to the cavity 7 through several ventilation holes. Cooling grooves are provided on both sides of the outer surface of the cabinet 1. Dustproof nets are installed on the inner side of the cooling grooves to improve the heat dissipation effect of the cabinet 1.

[0036] When using this energy storage device, first connect the power supply, pull out drawer 3, and place the lithium battery on top of shelf 1104. Under the action of gravity, shelf 1104 moves downward, causing rack 1401 to move downward, which in turn causes gear B1404 to rotate, thereby causing crossbar 1403 to rotate, which in turn causes bevel gear A1402 to rotate, which in turn causes bevel gear B1405 to rotate. Rotating rod 1407 rotates, and two threaded blocks 1406 move towards each other simultaneously, causing clamping plate 110... 1. Moving towards each other, limiting the lithium battery, electrode 1102 contacts the lithium battery, charging the lithium battery. When the lithium battery is above the shelf 1104, push plate 1302 is pressed downward under the gravity of the lithium battery. The upper surface of pin 1503 has an external thread. The threaded tube 1301 moves downward, causing pin 1503 to rotate in the opposite direction, thereby driving gear C1505 to rotate. Conveyor belt 1507 drives gear D1506 to rotate. The vertical shaft 1501 rotates, which in turn rotates gear A503, causing rack 1401 to move backward. This causes drawer 3 to move backward and retract into the inner side of storage slot 2. When charging is complete and the lithium battery needs to be removed, simply pull drawer 3 forward out of storage slot 2 using the handle. Drawer 3 moves forward, causing strip plate 501 and sawtooth A502 to move forward. Sawtooth A502 meshes with gear A503, causing gear A503 to rotate in the opposite direction, which in turn causes vertical shaft 1501 to rotate in the opposite direction. The rotation of the belt drives gear D1506 to rotate, which in turn drives gear C1505 to rotate, thereby driving pin 1503 to rotate. Threaded tube 1301 rotates upwards on the outside of pin 1503, causing push plate 1302 to pass through slot A1105 and push the lithium battery upwards, making it easier for workers to remove the lithium battery from the placement slot 10. This invention can charge lithium batteries of different sizes and can quickly remove charged lithium batteries, improving work efficiency.
