Description

Technical Field

[0001] This utility model relates to the field of charging cabinet technology, and in particular to a lithium battery charging cabinet with adjustable spacing for layered storage. Background Technology

[0002] A lithium battery charging cabinet is a device used to store and charge lithium batteries. It provides a safe storage and charging environment for lithium batteries and is commonly used in commercial and industrial settings, as well as public places such as airports and train stations.

[0003] A lithium battery safety charging cabinet is disclosed in Chinese utility model patent application number CN202420051748.3. It uses multiple temperature measuring devices to detect the temperature near multiple lithium batteries. When the temperature is too high, a blower is activated. The blower generates air and exhausts it through multiple air outlets to dissipate heat evenly from the multiple lithium batteries, which facilitates heat dissipation for each lithium battery and improves the performance.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the internal compartments have fixed sizes, which cannot accommodate the charging of lithium batteries of different specifications, reducing the practicality of the structure. Furthermore, the operation of moving lithium batteries up and down requires manual labor. For charging chambers at higher positions, it requires considerable effort to place and remove lithium batteries, resulting in greater charging intensity and difficulty, which is not conducive to more labor-saving use, and the overall use effect is not ideal. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a lithium battery charging cabinet with adjustable spacing for layered storage.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a lithium battery charging cabinet with adjustable spacing for layered storage, comprising a cabinet body and support legs, a partition plate is fixedly installed in the middle of the cabinet body, limit grooves are symmetrically opened on both sides of the cabinet body, slots are symmetrically provided at both ends of the partition plate, a drive plate is slidably connected between the slots and the limit grooves, a hydraulic cylinder is installed in the middle of the drive plate, the hydraulic cylinder is located inside the partition plate, a bearing groove is symmetrically opened on the top surface of the drive plate, second friction pads are symmetrically installed on both sides inside the bearing groove, a plurality of sets of second rollers are installed between the second friction pads, and plug-in plates are installed on the surface of the partition plate and on the inner wall of the cabinet.

[0007] By adopting the above technical solution, the cabinet is constructed from cold-rolled steel sheet, with a hollow interior forming a charging chamber. Support legs are bolted to the bottom. Symmetrical limiting grooves, which are vertical elongated slots, are opened on both sides of the cabinet to restrict the movement trajectory of the drive plate. The partition is horizontally fixed to the middle of the cabinet (by welding or bolts), dividing the cabinet into symmetrical upper and lower charging areas. Slots are opened at both ends of the partition, aligned with the limiting grooves, forming a sliding channel for the drive plate. A cavity is reserved inside the partition for installing a hydraulic cylinder. The hydraulic cylinder body is bolted to the bottom surface of the partition, and the piston rod passes upward through the partition and is threaded to the center of the bottom surface of the drive plate. The drive plate... The device consists of a rectangular metal plate with its two edges embedded in limiting grooves to form a sliding fit. A bearing groove (rectangular groove) is opened on the top surface of the drive plate. The two sides of the groove are fixed with second friction pads (rubber material) by adhesive or screws to increase the friction between the lithium battery and the bearing groove and prevent slippage. A second roller (hinged to the drive plate by bearings) is evenly installed between the two friction pads. The axis of the roller is perpendicular to the direction of movement of the drive plate to facilitate the lateral pushing of the lithium battery. The power strip is installed on the top edge of the partition and the inner wall of the cabinet (by buckles or screws) to connect to the power cord inside the cabinet and provide a charging interface. The position corresponds to the top of the adjustment plate for easy insertion and removal of the lithium battery.

[0008] Furthermore, several sets of sliding grooves are symmetrically opened on both sides of the partition and on both sides of the interior of the cabinet, and several sets of adjusting plates are inserted into the interior of the sliding grooves.

[0009] By adopting the above technical solution, the sliding groove is formed by evenly opening multiple sets of horizontal long grooves on both sides of the partition and the inner wall of the cabinet. The groove cross-section is T-shaped or dovetail-shaped, which is used to limit the vertical movement of the adjustment plate. The adjustment plate is a rectangular flat plate with raised sliders on both sides that match the sliding groove. After being inserted into the sliding groove, it can slide and be positioned in the horizontal direction. The first friction pad (rubber material) is pasted on the outer side of the top surface of the adjustment plate to prevent slipping and fix it when in contact with the inner wall of the cabinet / partition. The first roller (with the axis aligned with the depth direction of the cabinet) is installed on the inner side through a bearing to facilitate the horizontal pushing of the lithium battery into the charging position.

[0010] Furthermore, a first friction pad is installed on the outer side of the top of the adjusting plate, and a plurality of first rollers are installed on one end of the first friction pad on the inner side of the top of the adjusting plate.

[0011] By adopting the above technical solution, the first roller and the second roller form a continuous rolling surface, which reduces the frictional resistance when the lithium battery is pushed and pulled (compared to traditional planar sliding). At the same time, the first friction pad and the slide groove cooperate to provide lateral support and prevent the adjustment plate from shaking.

[0012] Furthermore, a control panel is installed on one side surface of the cabinet.

[0013] By adopting the above technical solution, the control panel is installed on the right side of the front of the cabinet, and is connected to the hydraulic cylinder and the cooling fan through wires. The panel integrates buttons (lifting control), display screen (displaying the current floor height and temperature) and emergency stop button. The operation interface is ergonomically designed (1.2m from the ground).

[0014] Furthermore, several sets of cooling fans are symmetrically installed on both sides of the cabinet.

[0015] By adopting the above technical solution, the cooling fan has symmetrical ventilation holes on both sides of the cabinet. The cooling fan (axial fan) is fixed to the inside of the hole with screws and is connected to the lithium battery charging area. It exhausts heat through forced convection to ensure heat dissipation efficiency.

[0016] Furthermore, support legs are symmetrically installed on both sides of the bottom of the cabinet.

[0017] By adopting the above technical solution, the support legs are made of metal and have rubber anti-slip pads at the bottom. They are adjustable to the bottom of the cabinet by bolts (e.g., screw-type lifting structure), which can finely adjust the level of the cabinet to adapt to uneven ground.

[0018] Furthermore, the partition has receiving slots on both sides located inside the cabinet.

[0019] By adopting the above technical solution, the receiving slot is a cavity located between the two sides of the partition and the inner wall of the cabinet. It is used to hide the hydraulic cylinder pipeline and heat dissipation air duct, keep the interior clean, and avoid the pipeline from contacting the lithium battery and causing wear.

[0020] Furthermore, a back panel is installed on the back of the cabinet, and the back panel is fixed to a fastening block by bolts. The fastening block is located on one side of the back of the cabinet.

[0021] By adopting the above technical solution, the back panel and fastening block are as follows: the back panel is a detachable metal plate, which is connected to the fastening block (welded to the cabinet) on the back of the cabinet by bolts. After disassembly, internal components such as the adjustment plate and power strip can be accessed, which is convenient for maintenance and spacing adjustment. The bolt fixing method ensures airtightness.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. In this application, the use of a drive plate and a hydraulic cylinder can assist personnel in raising and lowering lithium batteries. During the lithium battery charging process, personnel only need to place the lithium battery on the drive plate from a low position and push it at the corresponding height. After charging, the lithium battery is pulled up to move to the drive plate. The lithium battery can then be easily removed from a low position by lowering the drive plate. Compared with the traditional manual lifting and lowering method, this can effectively reduce the labor intensity of personnel and make it easier to use. It has the advantage of saving effort when charging.

[0024] 2. In this application, the cabinet has a back panel on the side. By opening the back panel, it is convenient for personnel to move the adjustment plate. By inserting the adjustment plate into the slide groove at different positions, the spacing between the adjustment plates can be adjusted, thereby meeting the charging needs of lithium batteries of different sizes, expanding the applicability of the device, improving the overall practicality, and making it easier to use. It has the advantages of adjustable cabinet spacing and strong practicality. Attached Figure Description

Detailed Implementation

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-4As shown in the embodiment of this application, a lithium battery charging cabinet with adjustable spacing for layered storage is disclosed, including a cabinet body 1 and support legs 19. A partition 3 is fixedly installed in the middle of the interior of the cabinet body 1. Limiting grooves 7 are symmetrically opened on both sides of the surface of the cabinet body 1. Slots are symmetrically provided at both ends of the surface of the partition 3. A drive plate 11 is slidably connected between the slots and the limiting grooves 7. A hydraulic cylinder 13 is installed in the middle of the surface of the drive plate 11. The hydraulic cylinder 13 is located inside the partition 3. A bearing groove 5 is symmetrically opened on the top surface of the drive plate 11. Second friction pads 12 are symmetrically installed on both sides inside the bearing groove 5. Several sets of second rollers 16 are installed between the second friction pads 12. The surface of the partition 3 and All inner walls of cabinet 1 are equipped with power strips 4. Cabinet 1 is made of cold-rolled steel plate and welded together. The interior is hollow to form a charging chamber. The bottom is fixed with support legs 19 by bolts. The front of cabinet 1 is open to facilitate the charging of lithium batteries. The two sides of cabinet 1 are symmetrically provided with limiting grooves 7, which are vertical elongated grooves used to limit the movement trajectory of drive plate 11. Partition 3 is horizontally fixed in the middle of cabinet 1 (by welding or bolts), dividing cabinet 1 into upper and lower symmetrical charging areas. The two ends of partition 3 are provided with slots that are aligned with the limiting grooves 7 to form a sliding channel for drive plate 11. The interior of partition 3 has a reserved cavity for installing hydraulic cylinder 13. The cylinder body of hydraulic cylinder 13 is fixed to the bottom surface of partition 3 by bolts, and the piston rod moves towards The upper part passes through the partition 3 and is threaded to the center of the bottom surface of the drive plate 11; the drive plate 11 is a rectangular metal plate with its two side edges embedded in the limiting grooves 7 to form a sliding fit. The top surface of the drive plate 11 has a bearing groove 5 (rectangular groove). The two sides of the groove are fixed with second friction pads 12 (rubber material) by adhesive or screws to increase the friction between the lithium battery and the bearing groove 5 and prevent slippage. The two friction pads are evenly installed with second rollers 16 (hinged to the drive plate 11 by bearings). The roller axis is perpendicular to the moving direction of the drive plate 11 to facilitate the lateral pushing of the lithium battery; the power strip 4 is installed on the top edge of the partition 3 and the inner wall of the cabinet 1 (by buckles or screws) to connect to the power cord inside the cabinet 1 and provide power. The charging port is located above the adjustment plate 8 for easy insertion and removal of lithium batteries. The lifting drive logic is as follows: the control panel 18 sends commands to the hydraulic cylinder 13, causing the piston rod to extend and retract, moving the drive plate 11 up and down along the limiting groove 7. For example, when placing a lithium battery, the drive plate 11 descends to the bottom of the cabinet 1, and personnel push the battery into the carrying groove 5. Then, the hydraulic cylinder 13 rises to the target shelf height, and the battery is pushed onto the adjustment plate 8 by the rolling of the second roller 16, completing the shelving process. The low-labor-intensity design ensures that the vertical lifting of the lithium battery is mechanically driven, requiring only horizontal pushing and pulling of the battery (using the rollers to reduce friction), avoiding the traditional manual vertical lifting action. This is especially suitable for large batteries, reducing the risk of lower back strain.

[0032] like Figure 1 and Figure 3As shown, several sets of sliding grooves 6 are symmetrically opened on both sides of the partition 3 and on both sides of the interior of the cabinet 1. Several sets of adjusting plates 8 are inserted into the sliding grooves 6. The sliding grooves 6 are: multiple sets of horizontal long grooves are evenly opened on both sides of the partition 3 and the interior wall of the cabinet 1. The groove cross-section is T-shaped or dovetail-shaped, which is used to limit the vertical movement of the adjusting plates 8. The adjusting plates 8 are: rectangular flat plates with raised sliders on both sides that match the sliding grooves 6. After being inserted into the sliding grooves 6, they can slide and be positioned in the horizontal direction. The first friction pad 9 (rubber material) is pasted on the outer side of the top surface of the adjusting plate 8 to prevent slipping and fix it when in contact with the interior wall of the cabinet 1 / partition 3. The first roller 10 (with the axis aligned with the depth direction of the cabinet 1) is installed on the inner side through a bearing to facilitate the horizontal pushing of the lithium battery into the charging position. By inserting the adjusting plates 8 into the sliding grooves 6 at different heights, the upper and lower layer spacing can be freely combined (for example: a lower layer spacing of 15cm is used to place large batteries, and an upper layer spacing of 10cm is used to place small batteries). After the back panel 14 is removed, the position of the adjusting plates 8 can be adjusted in batches from the back of the cabinet 1, which is convenient to operate.

[0033] like Figure 1 and Figure 3 As shown, a first friction pad 9 is installed on the outer side of the top of the adjustment plate 8. Several sets of first rollers 10 are installed on one end of the first friction pad 9 on the inner side of the top of the adjustment plate 8. The first rollers 10 and the second rollers 16 form a continuous rolling surface, which reduces the frictional resistance when the lithium battery is pushed and pulled (compared to traditional flat sliding). At the same time, the first friction pad 9 and the slide 6 cooperate to provide lateral support and prevent the adjustment plate 8 from shaking. Lithium battery loading: The control panel 18 is operated to lower the drive plate 11 to the bottom and push the lithium battery horizontally into the bearing groove 5. The second rollers 16 assist in sliding. The hydraulic cylinder 13 rises to the target height of the adjustment plate 8, and the personnel push the battery along the first rollers 10 into the charging position and connect the power strip 4 for charging. Charging and heat dissipation: During the charging process, the cooling fan 15 guides the airflow from the inside of the cabinet 1 to the outside, accelerates the gas flow, and avoids the charging temperature from being too high. Lithium battery unloading: After charging is completed, the drive plate 11 rises to the corresponding layer height, and the personnel pull the battery back to the bearing groove 5. The hydraulic cylinder 13 descends to the bottom and the battery is directly removed. No lifting action is required throughout the process.

[0034] like Figure 1 As shown, a control panel 18 is installed on one side of the cabinet 1. The control panel 18 is installed on the right side of the front of the cabinet 1 and is connected to the hydraulic cylinder 13 and the cooling fan 15 through wires. The panel integrates buttons (lifting control), display screen (displaying the current floor height and temperature) and emergency stop button. The operation interface is ergonomically designed (1.2m from the ground).

[0035] like Figure 1As shown, several sets of cooling fans 15 are symmetrically installed on both sides of the cabinet 1. Cooling fans 15: Cooling holes are symmetrically opened on both sides of the cabinet 1. The cooling fans 15 (axial fans) are fixed to the inside of the holes with screws and are connected to the lithium battery charging area. They exhaust heat through forced convection to ensure heat dissipation efficiency.

[0036] like Figure 1 As shown, support legs 19 are symmetrically installed on both sides of the bottom of the cabinet 1. The support legs 19 are made of metal and have rubber anti-slip pads on the bottom. They are adjustable to the bottom of the cabinet 1 by bolts (e.g., screw-type lifting structure) so that the level of the cabinet 1 can be finely adjusted to adapt to uneven ground.

[0037] like Figure 1 As shown, the partition 3 has a receiving groove 2 on both sides inside the cabinet 1. The receiving groove 2 is a cavity between the two sides of the partition 3 and the inner wall of the cabinet 1. It is used to hide the hydraulic cylinder 13 pipeline and heat dissipation air duct, keep the interior clean, and avoid the pipeline from contacting the lithium battery and causing wear.

[0038] like Figure 1 As shown, a back panel 14 is installed on the back of the cabinet 1. The back panel 14 is fixed to the fastening block 17 by bolts. The fastening block 17 is located on one side of the back of the cabinet 1. The back panel 14 is a detachable metal plate, which is connected to the fastening block 17 (welded to the cabinet 1) on the back of the cabinet 1 by bolts. After disassembly, internal components such as the adjustment plate 8 and the power strip 4 can be accessed, which is convenient for maintenance and spacing adjustment. The bolt fixing method ensures airtightness. Device effect: Labor-saving operation: Vertical lifting is mechanically driven, and horizontal movement is achieved by rollers, which reduces labor intensity and is especially suitable for single-person operation of heavy batteries. Flexible layering and adaptation: The spacing of the adjustment plates 8 can be freely adjusted within the range of 5-30cm, which is compatible with various specifications such as 18650 battery packs and energy storage batteries, improving equipment utilization. Safe heat dissipation design: Forced convection heat dissipation ensures that the battery temperature will not be too high during charging, reducing the risk of thermal runaway.

[0039] The working principle of the adjustable-spacing, layered lithium battery charging cabinet in this embodiment is as follows: During use, personnel can drive the extension and retraction of the hydraulic cylinder 13 via the control panel 18, thereby moving the drive plate 11 to a suitable position. When it is necessary to place and charge the lithium battery, the drive plate 11 can be moved to a lower position, and then personnel can place the lithium battery into the corresponding bearing groove 5 on the drive plate 11. Then, by reversing the movement of the hydraulic cylinder 13, the drive plate 11 can be raised to the height of the corresponding chamber. Then, personnel can push the lithium battery, so that it moves to the adjusting plate 8 by the rotation of the first roller 10 and the second roller 16, realizing the placement operation of the lithium battery. Then, personnel can charge the lithium battery through the power strip 4 and the power cord. Similarly, when the lithium battery is fully charged... After completion, personnel can pull the lithium battery and move it onto the drive plate 11. Then, by lowering the drive plate 11, the battery can be quickly removed. Since the lithium battery's up and down operations are assisted by the drive plate 11, it effectively reduces the labor intensity of personnel compared to the traditional manual lifting and lowering method, making it easier to use. At the same time, the cabinet 1 has a back panel 14 on its side. By opening the back panel 14, personnel can easily move the adjustment plate 8. By inserting the adjustment plate 8 into the slide groove 6 at different positions, the spacing between the adjustment plates 8 can be adjusted, thereby meeting the charging needs of lithium batteries of different sizes, expanding the applicability of the device, improving the overall practicality, and facilitating better use. The device as a whole has the advantages of labor-saving charging, adjustable spacing of the cabinet 1, and strong practicality.
