Description

Technical Field

[0001] This invention relates to the field of battery swapping cabinet technology, specifically a moisture-proof battery swapping cabinet for logistics stations. Background Technology

[0002] Currently, a battery swapping cabinet is a facility used to store and replace batteries for electric equipment (such as electric vehicles, electric forklifts, etc.). It allows users to quickly replace batteries when needed, thereby improving the efficiency and range of the equipment. The battery swapping cabinet is usually designed with battery storage racks, battery charging systems, and mechanized or automated battery replacement devices.

[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: To prevent moisture inside the battery swapping cabinet from affecting battery charging and the overall use of the cabinet, dehumidifying and moisture-proofing materials such as quicklime and activated carbon are added inside. These materials can absorb moisture and can be heated and dried for repeated use. However, since there is no heating device inside the cabinet, staff must manually collect moisture frequently. This inconvenience of frequent collection and unified heating leads most vendors to discard the materials and replace them with new ones, resulting in unnecessary waste of resources. Some vendors even avoid replenishing the moisture-absorbing materials to reduce maintenance costs, which is harmful to both the equipment and the users. Summary of the Invention

[0004] The purpose of this invention is to provide a moisture-proof battery swapping cabinet for logistics stations to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a moisture-proof battery swapping cabinet for logistics stations, comprising a battery swapping cabinet, wherein a plurality of battery swapping slots for charging batteries are provided on one side of the battery swapping cabinet, and each battery swapping slot has a moisture-proof component on its innermost side for preventing moisture inside the battery swapping slot, and each moisture-proof component has a circulation component on one side for automatically drying and dehumidifying the moisture-proof component, wherein a driving component for moving the moisture-proof component is provided inside the battery swapping slot, and the moisture-proof component includes a moisture-absorbing plate disposed inside the battery swapping slot and a first sliding plate fixedly installed on both sides of the moisture-absorbing plate. Each of the first sliding strips has a second sliding strip slidably fitted on one side, and a connecting block is fixedly installed on one side of each of the moisture-absorbing plates. Both of the second sliding strips are fixedly installed to the inner wall of the adjacent battery swapping tank. Multiple connecting ports are opened on both sides of the battery swapping cabinet, and each connecting port is connected to the adjacent battery swapping tank. One end of each second sliding strip passes through the adjacent connecting port. The circulation component includes two third sliding strips arranged on one side of the battery swapping cabinet and a protective plate fixedly installed on one side of the two third sliding strips and having a heating groove. A heating wire is fixedly installed inside the heating groove.

[0006] Once the moisture-absorbing time of the moisture-proof component is reached, the drive component will start, and the moisture-proof component will be pushed into the circulation component. The circulation component will heat the moisture-proof component, thereby drying it so that it can absorb moisture again. After the drying time is reached, the moisture-proof component will be reset by the drive component, thereby absorbing the moisture inside the battery swapping cabinet again.

[0007] Preferably, the third sliding bar has the same structure as the second sliding bar, and each of the third sliding bars is rotatably engaged with the adjacent second sliding bar;

[0008] The third sliding bar and the second sliding bar have the same structure, which allows the first sliding bar to move back and forth on the third and second sliding bars with the moisture-absorbing plate without getting stuck.

[0009] Preferably, one end of each heating wire is electrically connected to a controller, one side of each controller is electrically connected to a first contact switch, one side of each first contact switch is provided with a second contact switch, multiple mounting holes are provided on both sides of the battery swapping cabinet, each second contact switch is installed inside an adjacent mounting hole, and each first contact switch is adapted to an adjacent second contact switch.

[0010] When the third sliding bar rotates, the first contact switch and the second contact switch come into contact, and the controller will control the heating wire to heat the damp moisture-absorbing plate.

[0011] Preferably, a sliding groove is provided on the inner wall of each of the battery swapping troughs, and a push plate is fixedly installed on one side of each of the moisture-absorbing plates. One side of each push plate passes through the sliding groove and extends into the interior of the battery swapping cabinet.

[0012] The push plate moves along the sliding groove, which pushes the moisture-absorbing plate, allowing the moisture-absorbing plate to move inside the battery swapping tank.

[0013] Preferably, a push rod is fixedly installed on one side of each push plate, a first connecting plate is fixedly installed at one end of each push rod, and a push block is fixedly installed at both ends of each first connecting plate. Multiple push ports are opened on both sides of the battery swapping cabinet, each push port is connected to the inside of the battery swapping cabinet, and one end of each push block passes through the adjacent push port.

[0014] When the push plate moves, it causes the push rod to push the first connecting plate, thereby pushing the first connecting plate and the push block out of the push port. This causes the push block to push the adjacent third sliding bar, allowing the first sliding bar to move smoothly onto the third sliding bar.

[0015] Preferably, the drive assembly includes a servo motor disposed inside the battery swapping cabinet, a drive rod fixedly mounted on the output end of the servo motor, a plurality of first bevel gears fixedly sleeved on the drive rod, and second bevel gears meshing with both sides of each first bevel gear. A threaded post is fixedly mounted on one side of each second bevel gear. One end of each threaded post is threaded through an adjacent push plate and rotatably mounted to the inner wall of the battery swapping cabinet. A support plate fixedly mounted to the inner wall of the battery swapping cabinet is rotatably sleeved on each threaded post.

[0016] The rotation of the drive rod causes the first bevel gear to drive the second bevel gear to rotate, and finally the rotation of the threaded column causes the push plate to move with the moisture-absorbing plate, thus completing the drying of the moisture-absorbing plate.

[0017] Preferably, multiple protection plates are evenly distributed from top to bottom on both sides of the battery swapping cabinet. A synchronization block is fixedly installed between two adjacent protection plates. Elastic bands are fixedly installed on the sides of the uppermost and lowermost protection plates. The end of the elastic band away from the protection plate is fixedly connected to the inner wall of the battery swapping cabinet.

[0018] The elastic band will pull the protective plate to close, and the synchronization block will make all the protective plates on the same side close synchronously.

[0019] Each of the protective plates is provided with a sealing plate at one end near the second sliding strip, and two first moving grooves are opened on one side of each sealing plate. Each first moving groove is slidably fitted with a limiting strip that is fixedly installed with the battery swapping cabinet.

[0020] The sealing plate will move along the limit strip to prevent deviation.

[0021] Each of the protective plates and each of the sealing plates is fixedly installed with a U-shaped mounting plate on one side. A first limiting rod is installed between the two mounting plates, and the two ends of the first limiting rod are rotatably connected to the two mounting plates through a rotating shaft.

[0022] When the protective plate is pushed open or closed, the first limit rod will push or pull the sealing plate, thereby allowing the sealing plate to close or open the connection.

[0023] Preferably, the bottom of the inner cavity of the battery swapping cabinet has two rotating slots, each of which is equipped with a small motor, and each of the small motors has multiple fan blades fixedly installed on its output shaft;

[0024] When the small motor starts, the fan blades will rotate, thereby expelling the hot air inside the battery swapping cabinet. This can both accelerate the drying of the moisture-absorbing plates and expel moisture from the air outlet pipe.

[0025] Each of the rotating slots has a first fixing block fixedly installed on its inner wall. A third contact switch is fixedly installed on one side of each first fixing block. A fourth contact switch is provided on one side of each third contact switch. A second fixing block is fixedly installed on one side of each fourth contact switch. A second limiting rod is fixedly installed on one side of each second fixing block. A second connecting plate is slidably sleeved on one end of each second limiting rod. One end of each second connecting plate is fixedly installed to one side of an adjacent push plate. A push spring is sleeved on each second limiting rod.

[0026] When the push plate moves, it causes the second connecting plate to push the second limit rod, thereby making the third contact switch and the fourth contact switch contact, allowing the small motor to be powered on and started.

[0027] Each of the rotating slots has a second moving slot on its inner wall, and each of the second moving slots has a sliding block that is slidably fitted inside. Each of the sliding blocks is fixedly installed with an adjacent second fixed block.

[0028] The sliding block, in conjunction with the second moving slot, can restrict the movement direction of the second fixed block and prevent the second fixed block from shifting.

[0029] Preferably, protective covers are fixedly installed on both sides of the battery swapping cabinet, and each protective cover has a maintenance door on one side;

[0030] The protective cover will protect the equipment from rain.

[0031] Each of the protective covers has an air outlet at the top of its inner cavity, an air outlet pipe is installed on each air outlet, and a check valve is installed inside each air outlet pipe.

[0032] Moisture will be discharged through the vent pipe, and the check valve will prevent outside air from entering the protective cover.

[0033] Preferably, each of the battery swapping slots is fixedly installed with a baffle, and each baffle is provided with a plurality of ventilation holes for ventilation.

[0034] The baffle will prevent the battery from accidentally hitting the moisture-absorbing plate during replacement.

[0035] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:

[0036] 1. The moisture-proof component inside the battery swapping trough absorbs the moisture inside the battery swapping cabinet. Furthermore, the moisture-absorbing plate in the moisture-proof component can repeatedly absorb moisture after drying, achieving the purpose of recycling and reducing maintenance costs.

[0037] 2. The moisture-proof component works in conjunction with the circulation component. When the moisture-proof component absorbs moisture, the circulation component heats the moisture-proof component, causing the moisture inside the moisture-proof component to evaporate. Once the moisture-proof component is dry, it can continue to absorb moisture from inside the battery swapping cabinet, thus keeping the inside of the battery swapping cabinet dry.

[0038] 3. The drive component moves the moisture-proof component, and in conjunction with the drying of the circulation component, the damp moisture-proof component can be automatically pushed onto the circulation component for drying without human intervention. After drying, it can return to the inside of the battery swapping cabinet to continue absorbing moisture. This eliminates the need for manual drying operations and allows the drying process to be carried out automatically according to the set time, thus achieving automated drying.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please see Figures 1 to 8 This invention provides a technical solution: a moisture-proof battery swapping cabinet for logistics stations, including a battery swapping cabinet 1. Multiple battery swapping slots 2 for charging batteries are provided on one side of the battery swapping cabinet 1. Each battery swapping slot 2 has a moisture-proof component on its innermost side to prevent moisture inside. Each moisture-proof component has a circulation component on one side that allows it to automatically dry and circulate moisture. Inside the battery swapping cabinet 1 is a drive component that moves the moisture-proof components. When the moisture absorption time of the moisture-proof components is reached, the drive component is activated, and the moisture-proof components are pushed into the circulation component. The circulation component heats the damp moisture-proof components, making them dry and able to absorb moisture again. After the drying time is reached, the moisture-proof components are reset by the drive component, thereby absorbing moisture from inside the battery swapping cabinet 1 again.

[0050] Please see Figure 6The moisture-proof component includes a moisture-absorbing clamp 301 set inside the battery swapping tank 2, first sliding strips 302 fixedly installed on both sides of the moisture-absorbing clamp 301, a second sliding strip 303 slidably fitted on one side of each first sliding strip 302, a connecting block fixedly installed on one side of each moisture-absorbing clamp 301, and two second sliding strips 303 fixedly installed to the inner wall of the adjacent battery swapping tank 2. Multiple connecting ports are opened on both sides of the battery swapping cabinet 1. The moisture-absorbing clamp 301 has three layers: two high-temperature resistant clamping mesh layers, which can be made of metals such as iron; and a moisture-absorbing layer between the two clamping mesh layers, which is made of quicklime, activated carbon, or other substances that can absorb moisture and can be reused after being heated to remove moisture. The moisture-absorbing clamp 301 is installed on one side of the connecting block and can be disassembled for replacement. The first sliding strip 302 can slide the moisture-absorbing clamp 301 out of the battery swapping tank 2 through the connecting port to facilitate heating and drying.

[0051] Please see Figure 2 , Figure 3 , Figure 6 and Figure 7 Each connecting port is connected to the adjacent battery swapping tank 2. One end of each second sliding bar 303 passes through the adjacent connecting port. The circulation component includes two third sliding bars 401 set on one side of the battery swapping cabinet 1 and a protective plate 402 fixedly installed on one side of the two third sliding bars 401 and having a heating groove. A heating wire 403 is fixedly installed inside the heating groove. The third sliding bars 401 and the second sliding bars 303 have the same structure. Each third sliding bar 401 is rotatably engaged with the adjacent second sliding bar 303. The third sliding bars 401 and the second sliding bars 303 have the same structure, which allows the first sliding bar 302 to move back and forth on the third sliding bar 401 and the second sliding bar 303 without being stuck. When the first sliding bar 302 slides onto the third sliding bar 401 with the moisture-absorbing plate 301, the heating wire 403 will heat and dry the damp moisture-absorbing plate 301.

[0052] Please see Figure 6 and Figure 7 Each heating wire 403 is electrically connected to a controller 6 at one end, and each controller 6 is electrically connected to a first contact switch 7 on one side. Each first contact switch 7 is provided with a second contact switch 8 on one side. Multiple mounting holes are provided on both sides of the battery swapping cabinet 1. Each second contact switch 8 is installed inside an adjacent mounting hole. Each first contact switch 7 is matched with an adjacent second contact switch 8. After the first contact switch 7 and the second contact switch 8 come into contact, the controller 6 will control the heating wire 403 to heat and dry the damp moisture-absorbing plate 301.

[0053] Please see Figure 3 , Figure 4 and Figure 6Each battery swapping trough 2 has a sliding groove on its inner wall. Each connecting block has a push plate 9 fixedly installed on one side. One side of each push plate 9 passes through the sliding groove and extends into the inside of the battery swapping cabinet 1. The push plate 9 moves along the sliding groove and pushes the moisture-absorbing plate 301, allowing the moisture-absorbing plate 301 to move inside the battery swapping trough 2.

[0054] Please see Figure 3 , Figure 4 and Figure 6 Each push plate 9 has a push rod 10 fixedly installed on one side, a first connecting plate 11 fixedly installed at one end of each push rod 10, and a push block 12 fixedly installed at both ends of each first connecting plate 11. Multiple push ports are opened on both sides of the battery swapping cabinet 1. Each push port is connected to the inside of the battery swapping cabinet 1. One end of each push block 12 passes through the adjacent push port. When the push plate 9 moves, the push rod 10 will push the first connecting plate 11, thereby pushing the first connecting plate 11 and the push block 12 out of the push port. This will allow the push block 12 to push the adjacent third sliding bar 401, so that the first sliding bar 302 can move smoothly onto the third sliding bar 401.

[0055] Please see Figure 3 and Figure 4 The drive assembly includes a servo motor 501 installed inside the battery swapping cabinet 1, a drive rod 502 fixedly installed on the output end of the servo motor 501, multiple first bevel gears 503 fixedly sleeved on the drive rod 502, and second bevel gears 504 meshing with both sides of each first bevel gear 503. Each second bevel gear 504 has a threaded post 505 fixedly installed on one side. One end of each threaded post 505 is threaded through the adjacent push plate 9 and rotatably installed with the inner wall of the battery swapping cabinet 1. Each threaded post 505 has a support plate rotatably sleeved on it and fixedly installed with the inner wall of the battery swapping cabinet 1. When the drive rod 502 rotates, the first bevel gear 503 drives the second bevel gear 504 to rotate. Finally, the rotation of the threaded post 505 causes the push plate 9 to move with the moisture-absorbing clamp 301, thus completing the drying of the moisture-absorbing clamp 301.

[0056] Please see Figure 2 and Figure 3 Multiple protective plates 402 are evenly distributed from top to bottom on both sides of the battery swapping cabinet 1. A synchronization block 14 is fixedly installed between two adjacent protective plates 402. Elastic bands 13 are fixedly installed on the sides of the uppermost and lowermost protective plates 402. The end of the elastic band 13 away from the protective plate 402 is fixedly connected to the inner wall of the battery swapping cabinet 1. After the first connecting plate 11 and the pushing block 12 retract into the battery swapping cabinet 1, the elastic band 13 will pull the protective plate 402 to make the third sliding strip 401 fit against the battery swapping cabinet 1.

[0057] Each protection plate 402 is provided with a sealing plate 15 at one end near the second sliding strip 303. Two first moving grooves are opened on one side of each sealing plate 15. A limiting strip 16 fixedly installed with the battery swapping cabinet 1 is slidably fitted inside each first moving groove. The sealing plate 15 will be pulled by the protection plate 402 to seal the connection port and prevent external moisture from entering the battery swapping cabinet 1.

[0058] Each protective plate 402 and each sealing plate 15 are fixedly installed with a U-shaped mounting plate 17 on one side. A first limiting rod 18 is installed between the two mounting plates 17. The two ends of the first limiting rod 18 are rotatably connected to the two mounting plates 17 through a rotating shaft. When the protective plate 402 moves, the first limiting rod 18 will push and pull the sealing plate 15, so that the sealing plate 15 can seal or open the communication port.

[0059] Please see Figure 3 , Figure 4 and Figure 5 Two rotating slots are opened at the bottom of the inner cavity of the battery swapping cabinet 1. Each rotating slot is equipped with a small motor 19. Multiple fan blades 20 are fixedly installed on the output shaft of each small motor 19. When the small motor 19 is started, the fan blades 20 will rotate, so that airflow will be generated inside the battery swapping cabinet 1, allowing the airflow containing water vapor to pass through the connecting port and exhaust pipe and be discharged.

[0060] Each rotating slot has a first fixing block fixedly installed on its inner wall. A third contact switch 21 is fixedly installed on one side of each first fixing block. A fourth contact switch 22 is provided on one side of each third contact switch 21. A second fixing block is fixedly installed on one side of each fourth contact switch 22. A second limiting rod 23 is fixedly installed on one side of each second fixing block. A second connecting plate 24 is slidably sleeved on one end of each second limiting rod 23. One end of the second limiting rod 23 passes through the second connecting plate 24 and is fixedly connected to the limiting ring. The limiting ring limits the second limiting rod 23 to prevent it from separating from the second connecting plate 24. One end of each second connecting plate 24 is fixedly installed on one side of the adjacent push plate 9. A push spring is sleeved on each second limiting rod 23. When the push plate 9 moves, the second connecting plate 24 pushes the push spring, thereby making the fourth contact switch 22 contact the third contact switch 21, thus starting the small motor 19.

[0061] Each rotating groove has a second moving groove on its inner wall. Each second moving groove has a sliding block that is slidably fitted inside. Each sliding block is fixedly installed with the adjacent second fixed block. The sliding block, in conjunction with the second moving groove, can restrict the movement of the second fixed block and prevent the movement of the second fixed block from causing deviation.

[0062] Please see Figure 1 and Figure 8 Both sides of the battery swapping cabinet 1 are fixedly equipped with protective covers 25. Each protective cover 25 has a maintenance door 26 on one side. The protective covers 25 will prevent external rainwater and moisture from entering the battery swapping cabinet 1.

[0063] Each protective cover 25 has an air vent at the top of its inner cavity, and each air vent is equipped with an air vent pipe 27. Each air vent pipe 27 is equipped with a check valve. The check valve prevents external moisture from entering the protective cover 25, while also allowing moisture inside the protective cover 25 to escape.

[0064] Please see Figure 2 Each battery swapping slot 2 has a baffle 28 fixedly installed inside. Each baffle 28 has multiple ventilation holes for ventilation. The baffle 28 will prevent the battery from accidentally hitting the moisture-absorbing plate 301 during replacement.

[0065] Working principle: The interval time for each start of the servo motor 501 to dry is set in advance. The drying time is the total time for the servo motor 501 to rotate forward after starting, then stop for a period of time and then rotate in the reverse direction. There will be a relatively long interval between each cycle to facilitate the absorption of moisture by the moisture-absorbing plate 301.

[0066] The servo motor 501 is a very mature existing technology. Through programming and servo controller settings, users can control the start and stop of the servo motor 501, and the rotation angle after starting can be set.

[0067] Once the servo motor 501 is set, you need to wait for a period of time for the moisture-absorbing plate 301 to absorb the moisture. This waiting time needs to be set.

[0068] After the moisture-absorbing clamp 301 becomes damp, the servo motor 501 starts and the drive rod 502 rotates. This causes the first bevel gear 503 to drive the second bevel gear 504 to rotate, which in turn causes the threaded column 505 to rotate. The rotation of the threaded column 505 causes the push plate 9, which is threaded with it, to move. When the push plate 9 moves, it pushes the moisture-absorbing clamp 301 and pushes it out of the communication port.

[0069] When the pusher plate 9 pushes the moisture-absorbing clamp 301, it also pushes the first connecting plate 11 and the two push blocks 12, pushing the first connecting plate 11 and the two push blocks 12 out from the adjacent push port. In this way, before the moisture-absorbing clamp 301 moves out of the power exchange tank 2, the push block 12 will first contact the third sliding bar 401, thus pushing the third sliding bar 401 in advance. The third sliding bar 401 is rotatably connected to the second sliding bar 303, so after being pushed, it will dock with the second sliding bar 303, so that the first sliding bar 302 can carry the moisture-absorbing clamp 301 back and forth on the second sliding bar 303 and the third sliding bar 401 without being stuck. Because the connecting port has a width, the moisture-absorbing clamp 301 has enough movement stroke. After the third sliding bar 401 docks with the second sliding bar 303, the moisture-absorbing clamp 301 will be pushed out.

[0070] After the third sliding bar 401 is pushed, the protective plate 402 will push the first limiting rod 18, causing the first limiting rod 18 to move, thereby opening the blocked connection port, allowing the moisture-absorbing plate 301 to pass through the connection port.

[0071] When the third sliding bar 401 is connected to the second sliding bar 303, not only will the moisture-absorbing plate 301 be pushed onto the third sliding bar 401, but the first contact switch 7 and the second contact switch 8 will also come into contact. When the controller 6 is powered on, the heating wire 403 will be heated. At this time, the moisture-absorbing plate 301 has moved to the side of the heating wire 403 and is waiting to be heated.

[0072] As the push plate 9 moves, it also moves the second connecting plate 24. The movement of the second connecting plate 24 causes the push spring to move, thereby pushing the second fixed block. This causes the fourth contact switch 22 on the second fixed block to contact the third contact switch 21 on the first fixed block. When they contact each other, the small motor 19 is started, which causes the fan blade 20 to rotate. This generates airflow inside the battery swapping cabinet 1, sending the hot air from the internal battery charging into the protective cover 25 through the connecting port. This not only speeds up the drying of the moisture-absorbing plate 301 but also cools the inside of the battery swapping cabinet 1 to a certain extent. Finally, the hot air is discharged from the air outlet pipe 27, and the check valve does not block the outward flow of internal air.

[0073] After heating is complete, the servo motor 501 starts to reverse, so the push plate 9 pulls the moisture-absorbing plate 301 back to its original position to continue absorbing moisture. The first connecting plate 11 and the two push blocks 12 are also retracted into the battery swapping cabinet 1. The third sliding bar 401 loses its resistance, and the two elastic bands 13 pull the adjacent protection plate 402. Since all the protection plates 402 on the same side are fixed by the synchronization block 14, all the protection plates 402 on the same side will rotate, eventually causing the third sliding bar 401 to rotate and stick tightly to the outer shell of the battery swapping cabinet 1. With the pull of the first limit rod 18, the sealing plate 15 can be pulled to the connection port to seal and block the connection port, preventing external moisture from entering the battery swapping cabinet 1.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
