Description

Technical Field

[0001] This invention relates to the field of battery swapping cabinet technology, and in particular to a lock body structure for a battery swapping cabinet. Background Technology

[0002] With the widespread use of electric two-wheelers, battery swapping cabinets, which allow users to quickly and conveniently replace batteries, have gradually become important equipment for providing battery replacement services. Therefore, the locking device of the swapping cabinet is particularly important for protecting the safety and reliability of the battery. Currently, the locking devices of swapping cabinets on the market are easily deceived by false electrical signals during the locking process, leading to battery loss, or they cannot perform emergency unlocking when the system is powered off, preventing users from successfully removing the battery in a power outage. Summary of the Invention

[0003] This invention provides a lock body structure for a battery swapping cabinet, which can improve the anti-theft effect of the cabinet, has high locking efficiency, and facilitates emergency unlocking in the event of a power outage.

[0004] This invention provides a lock body structure for a battery swapping cabinet, comprising: a main body, a latch assembly, a motor drive assembly, and a mechanical unlocking assembly. The latch assembly is disposed within the main body and is used to lock the battery inside the cabinet. The latch assembly has a first state of locking the battery and a second state of unlocking the battery. The latch assembly includes a latch and a latch transmission part capable of driving the latch to move. The motor drive assembly is disposed within the main body and includes a drive part and a first transmission gear. The drive part can drive the first transmission gear to rotate, and the latch transmission part is drively connected to the first transmission gear. The mechanical unlocking assembly is disposed within the main body, and an unlocking key can actuate the mechanical unlocking assembly, causing the mechanical unlocking assembly to drive the latch transmission part to move. Both the motor drive assembly and the mechanical unlocking assembly can drive the latch assembly to switch from the first state to the second state.

[0005] This invention provides a locking assembly and a mechanical unlocking assembly within the lock body structure of the battery swapping cabinet. The locking assembly includes a latch and a latch transmission part. The latch transmission part drives the latch to extend and separate from the battery or retract and connect to the battery, thereby unlocking or locking the battery. By directly locking the battery with the latch, no key is required. After battery swapping, simply pushing the battery in completes the locking process. This convenient operation helps prevent theft of batteries caused by using a false lock or falsely closing the door to send a false closing signal to the system. It also helps prevent battery theft caused by forgetting to close the door after battery swapping. In this invention, both the motor drive assembly and the mechanical unlocking assembly can drive the locking assembly to switch from a first state to a second state to lock or unlock the battery inside the battery swapping cabinet. The mechanical unlocking assembly also facilitates emergency unlocking of the battery swapping cabinet in the event of a power outage, allowing users to easily remove the battery even when the power is off.

[0006] According to the foregoing embodiments of the present invention, the latch transmission part includes: a conversion cam, a guide member, and a first elastic member. The conversion cam includes a wheel body and a groove disposed on the outer periphery of the wheel body, and a first transmission gear is drivenly connected to the conversion cam. The guide member is drivenly connected to the latch in a first direction, and the rotation of the conversion cam allows at least a portion of the structure of the guide member to be located in or away from the groove. The first elastic member is connected to the latch and provides elastic restoring force for the latch to switch from a second state to a first state. When at least a portion of the structure of the guide member is away from the groove, the guide member drives the latch to move and squeezes the first elastic member, causing the latch to separate from the battery, thereby unlocking the battery in the battery swapping cabinet.

[0007] According to the foregoing embodiments of the present invention, the guide member includes a guide pin and a guide ball. The guide ball is disposed in contact with the guide pin, and the rotation of the switching cam allows the guide ball to be positioned within or away from the slot.

[0008] According to the aforementioned embodiments of the present invention, the main body further includes a first boss, and the motor drive assembly further includes a second transmission gear. The first transmission gear, the second transmission gear, and the conversion cam are capable of transmission connection. The outer periphery of the second transmission gear also includes a second boss. During the rotation of the second transmission gear, the first boss and the second boss abut against each other, which can restrict the rotation of the second transmission gear.

[0009] According to the aforementioned embodiments of the present invention, the first transmission gear and the second transmission gear are both incomplete gears.

[0010] According to the aforementioned embodiments of the present invention, a reset member is further provided on the second transmission gear. The first transmission gear is meshed with the second transmission gear, and the second transmission gear rotates to compress the reset member. In the state where the first transmission gear and the second transmission gear are separated, the reset member can provide an elastic restoring force to the second transmission gear.

[0011] According to the aforementioned embodiments of the present invention, the main body further includes a sliding hole, and the latch transmission part further includes a sliding bushing. The sliding bushing mounts the latch in the sliding hole along the second direction. The unlocking key actuates the mechanical unlocking assembly, causing the mechanical unlocking assembly to contact the sliding bushing and drive the sliding bushing to move. The sliding bushing can drive the latch to move within the sliding hole.

[0012] According to the foregoing embodiments of the present invention, the mechanical unlocking assembly includes an unlocking paddle with an inclined surface capable of contacting the sliding bushing. In the mechanical unlocking state, the inclined surface can apply pressure to the sliding bushing, and the sliding bushing can push the latch to move within the sliding hole under the action of external force.

[0013] According to the foregoing embodiments of the present invention, the mechanical unlocking assembly further includes a second elastic member. The second elastic member is connected to the unlocking paddle. When the unlocking key moves the mechanical unlocking assembly, the unlocking paddle compresses the second elastic member. When the unlocking key is removed from the unlocking paddle, the second elastic member provides an elastic restoring force to the unlocking paddle, causing the unlocking paddle to separate from the sliding bushing.

[0014] According to the foregoing embodiments of the present invention, the battery swapping cabinet lock body structure further includes: a plug assembly and a detection assembly. The plug assembly is connected between the main body and the battery. The detection assembly is disposed on the plug assembly, and the detection assembly is capable of detecting the battery status and sending a detection signal.

[0015] According to the aforementioned embodiment of the present invention, the outer periphery of the first transmission gear further includes a third boss, and the motor drive assembly further includes a position sensor. During the rotation of the first transmission gear, the position sensor can sense the position signal of the third boss and send a position signal, and the drive unit can receive the position signal and stop driving the rotation of the first transmission gear.

[0040] This invention provides a lock body structure for a battery swapping cabinet, which can improve the anti-theft effect of the cabinet, has high locking efficiency, and facilitates emergency unlocking in the event of a power outage.

[0041] like Figure 1 As shown, this embodiment of the invention provides a battery swapping cabinet lock body structure, which is installed in the battery swapping cabinet 500 to lock or unlock the battery 600 inside the battery swapping cabinet 500.

[0042] like Figure 2 As shown, the lock body structure of the battery swapping cabinet includes: a main body 100, a latch assembly 300, a motor drive assembly 200, and a mechanical unlocking assembly 400.

[0043] like Figure 2 As shown, the locking assembly 300 is disposed within the main body 100. The locking assembly 300 is used to lock the battery 600 inside the battery swapping cabinet 500. The locking assembly 300 has a first state of locking the battery 600 and a second state of unlocking the battery 600. The locking assembly 300 includes a latch 310 and a latch transmission part 320 capable of driving the latch 310 to move. In this embodiment, as... Figures 3 to 4 As shown, the lock body structure includes two sets of latching assemblies 300 arranged opposite to each other. The two sets of latching assemblies 300 respectively abut against or separate from one side of the bottom cover of the battery 600 to lock or unlock the battery 600.

[0044] like Figure 2As shown, the motor drive assembly 200 is disposed within the main body 100. The motor drive assembly 200 includes a drive unit 210 and a first transmission gear 220. The drive unit 210 can drive the first transmission gear 220 to rotate, and the latching transmission unit 320 is connected to the first transmission gear 220 in a transmission connection. In this embodiment, the drive unit 210 includes a motor, and the motor drive assembly 200 also includes a circuit board. The circuit board is electrically connected to the drive unit 210, and the circuit board controls the stop and rotation of the drive unit 210 through signals. The motor drive assembly 200 also includes a drive unit bracket 250, which mounts the drive unit 210 within the main body 100. When the drive unit 210 receives an unlocking command, the drive unit 210 drives the first transmission gear 220 to rotate, thereby driving the movement of the latching assembly 300 to unlock the battery 600.

[0045] like Figure 2 As shown, the mechanical unlocking component 400 is disposed inside the main body 100. The unlocking key can move the mechanical unlocking component 400 so that the mechanical unlocking component 400 can drive the latch transmission part 320 to move.

[0046] In this embodiment, both the motor drive assembly 200 and the mechanical unlocking assembly 400 can drive the latch assembly 300 to switch from the first state to the second state. For example... Figures 5 to 6 As shown, when the motor drive assembly 200 drives the latch assembly 300 to switch from the first state to the second state, the lock body structure is in electronic unlocking mode. The drive unit 210 sequentially drives the first transmission gear 220 and the latch transmission unit 320 to move, causing the latch 310 to extend and separate from the battery 600, thereby unlocking the battery 600 inside the battery swapping cabinet 500; Figure 7 As shown, when the mechanical unlocking component 400 drives the latch component 300 to switch from the first state to the second state, the lock body structure is in mechanical unlocking mode. The mechanical unlocking component 400 drives the latch transmission part 320 to move, so that the latch 310 extends and separates from the battery 600, thereby unlocking the battery 600 in the battery swapping cabinet 500. By setting the mechanical unlocking component 400, it is beneficial to realize the emergency unlocking function of the battery swapping cabinet 500 in the power failure state, and the user can also easily remove the battery 600 in the power failure state.

[0047] The technical solution of this invention provides a latch assembly 300 and a mechanical unlocking assembly 400 in the lock body structure of the battery swapping cabinet. The latch assembly 300 includes a latch 310 and a latch transmission part 320, which can drive the latch 310 to move. Figures 3 to 4As shown, when the latch 310 retracts inward, it contacts the bottom cover of the battery 600, securing the battery 600 and achieving the locking function. When the latch 310 extends outward, the bottom cover of the battery 600 no longer contacts the latch 310, unlocking the battery 600, allowing it to move freely in and out, thus achieving the unlocking function. By directly locking the battery 600 with the latch 310, no key is needed. After battery swapping, simply pushing the battery 600 in completes the locking process. This convenient operation helps prevent the use of false locks in the battery swapping cabinet 500 or the system from receiving a false closing signal, which could lead to theft of the battery 600. It also helps prevent the battery 600 from being stolen if the door is forgotten to be closed after swapping.

[0048] like Figure 8 As shown, the latch assembly 300 includes a mounting base 330, a latch 310 mounted on the mounting base 330, and a latch drive part 320 capable of sliding within the mounting base 330. Figure 1 As shown, the locking transmission part 320 includes: a conversion cam 321, a guide member 322, and a first elastic member 323. The main body 100 includes a conversion cam mounting hole, in which the conversion cam 321 is mounted, and the conversion cam 321 moves synchronously with the first transmission gear 220. Figures 9 to 10 As shown, the conversion cam 321 includes a wheel body and a slot 3211 disposed on the outer periphery of the wheel body, and the first transmission gear 220 is connected to the conversion cam 321 for transmission. Figure 8 As shown, the guide member 322 and the latch 310 are connected in a driving direction S1. The guide member 322 includes a guide pin 3221 and a guide ball 3222. Figures 9 to 10 As shown, the guide ball 3222 abuts against the guide pin 3221. The rotation of the conversion cam 321 allows the guide ball 3222 to be positioned within or away from the slot 3211. The guide ball 3222 can drive the guide pin 3221 to slide. By changing the position of the guide ball 3222 within or outside the slot 3211, the locking and unlocking states of the lock body structure are changed, realizing the automatic unlocking and locking of the latch assembly 300. When the guide ball 3222 is within the slot 3211 of the conversion cam 321, the first elastic element 323 pushes the latch 310 inward toward the main body 100, and the latch 310 is in the locked state. When the guide ball 3222 is outside the slot 3211 of the cam, that is, when the guide ball 3222 contacts the sliding surface 3212 of the cam, the guide ball 3222 pushes the latch 310 outward toward the main body 100 through the guide pin 3221, and the latch 310 is in the unlocked state.

[0049] like Figure 8As shown, the first elastic element 323 is connected to the latch 310. The first elastic element 323 provides elastic restoring force for the latch 310 to switch from the second state to the first state. The first elastic element 323 is a spring. Figures 9 to 10 As shown, in the unlocked state, the guide ball 3222 leaves the slot 3211, and the guide pin 3221 drives the latch 310 to move and press the first elastic element 323, causing the latch 310 to separate from the battery 600, thereby unlocking the battery 600 in the battery swapping cabinet 500. The rotation of the conversion cam 321 causes the guide element 322 to be positioned in the slot 3211 or in contact with the sliding surface 3212, thereby pushing the latch 310 to disengage from or abut against the battery 600, achieving the unlocking and locking functions.

[0050] like Figure 2 As shown, the main body 100 also includes a sliding hole 120, and the locking transmission part 320 also includes a sliding bushing 324. For example... Figure 8 As shown, the sliding sleeve 324 installs the latch 310 into the sliding hole 120 along the second direction S2. The sliding hole 120 is an oblong hole. In the mechanical unlocking mode, the unlocking key moves the mechanical unlocking component 400, causing the mechanical unlocking component 400 to contact the sliding sleeve 324 and drive the sliding sleeve 324 to move. The sliding sleeve 324 can drive the latch 310 to move within the sliding hole 120. In this embodiment, the mounting base 330 also includes a fourth boss 331. The sliding sleeve 324 is mounted on the fourth boss 331. The sliding sleeve 324 and the latch 310 move simultaneously. The sliding sleeve 324 is an oil-impregnated bearing, which not only limits the latch 310, reducing friction and wear, but also facilitates the movement of the latch 310 along the guiding direction of the guide pin 3221, preventing the latch 310 from deviating or getting stuck. This enhances the stability and reliability of the latch 310's movement, thereby improving the response speed and efficiency of the lock body structure. In this embodiment, as shown... Figure 2 As shown, the locking assembly 300 also includes a first cover 340, which can close the sliding hole 120 and limit the sliding bushing 324.

[0051] In this embodiment, as Figure 2 As shown, the locking assembly 300 also includes a second cover 350. The first elastic element 323 is mounted on the second cover 350. The second cover 350 seals the interior of the locking assembly 300, restricting the position of the first elastic element 323 and preventing the automatic locking function of the locking assembly 300 from failing due to the first elastic element 323 being displaced and popped out. When the sliding bushing 324 is at its outer limit position of the main body 100 under the action of the mechanical unlocking assembly 400, the first elastic element 323 is in a compressed state and stores force; when the sliding bushing 324 is at its inner limit position of the main body 100, the first elastic element 323 pushes the latch 310 inward toward the mounting base 330, realizing the automatic locking function of the latch 310.

[0052] like Figures 11 to 13 As shown, the main body 100 also includes a first boss 110, and the motor drive assembly 200 also includes a second transmission gear 230. The first transmission gear 220, the second transmission gear 230, and the conversion cam 321 are capable of transmission connection. The outer periphery of the second transmission gear 230 also includes a second boss 231. During the rotation of the second transmission gear 230, the first boss 110 and the second boss 231 abut against each other, which can limit the rotation of the second transmission gear 230. The outer periphery of the second transmission gear 230 includes multiple second bosses 231. The second bosses 231 at different positions on the outer periphery of the second transmission gear 230 can abut against the first boss 110 respectively, so that the lock body mechanism switches between locking and unlocking modes. The first boss 110 and the second boss 231 cooperate with each other to limit the second transmission gear 230. The second transmission gear 230 can mesh with the first transmission gear 220. The second transmission gear 230 drives the conversion cam 321 to rotate through the power transmitted by the first transmission gear 220.

[0053] like Figure 2 As shown, the motor drive assembly 200 also includes a protective cover 260, which can protect the engagement between the first transmission gear 220 and the second transmission gear 230, and at the same time play a role in dust prevention and fixing of the first transmission gear 220 and the second transmission gear 230.

[0054] like Figure 2 As shown, the second transmission gear 230 is also provided with a reset member 232. In the motor unlocked mode, the first transmission gear 220 and the second transmission gear 230 are engaged, and the second transmission gear 230 rotates to compress the reset member 232. When the first transmission gear 220 and the second transmission gear 230 are disengaged, the reset member 232 can provide an elastic restoring force to the second transmission gear 230. The reset member 232 is a reset torsion spring.

[0055] In this embodiment, the reset member 232 is mounted on the second transmission gear 230. When the first transmission gear 220 meshes and rotates with the second transmission gear 230, the reset member 232 enters a storage state. After unlocking, when the first transmission gear 220 and the second transmission gear 230 are no longer in contact, the reset member 232 releases its elastic force, causing the second transmission gear 230 to rotate and spring back, thereby driving the latch 310 to relock the battery 600, achieving automatic locking. When the first boss 110 touches the second boss 231, the second transmission gear 230 stops springing back. By setting the reset member 232, the first boss 110, and the second boss 231, the automatic reset of the second transmission gear 230 after unlocking is ensured. The cooperative design of the first transmission gear 220 and the second transmission gear 230 ensures that the second transmission gear 230 automatically returns to its initial position after each unlocking, avoiding gear grinding and improving the reliability of locking.

[0056] Furthermore, the lock body structure also features a delayed automatic locking function after unlocking, ensuring sufficient time for removing the battery 600 after unlocking. The delayed automatic locking time depends on the storage capacity of the reset component 232 and the second transmission gear 230. Subsequently, the second transmission gear 230 automatically springs back to lock, avoiding prolonged unlocking and ensuring that the lock body structure automatically returns to the locked state after removing the battery 600, thus improving security.

[0057] like Figure 7 As shown, the mechanical unlocking assembly 400 includes an unlocking paddle 410, which has an inclined surface 411 capable of contacting the sliding sleeve 324. In the mechanical unlocking mode, the inclined surface 411 can apply pressure to the sliding sleeve 324, such as... Figure 2 As shown, the sliding bushing 324 can push the latch 310 to move within the sliding hole 120 under external force. In this embodiment, when the operator uses a special unlocking key to push the unlocking lever 410, the inclined surface 411 of the unlocking lever 410 contacts the sliding bushing 324 in the latch assembly 300, and pushes the sliding bushing 324 outward from the main body 100, thereby causing the latch 310 to extend outward. The bottom cover of the battery 600 no longer contacts the latch 310, the latch 310 unlocks the battery 600, and the battery 600 can freely enter and exit, realizing the unlocking function.

[0058] like Figure 2As shown, the mechanical unlocking assembly 400 also includes a second elastic element 420. The second elastic element 420 is connected to the unlocking lever 410. When the unlocking key moves the mechanical unlocking assembly 400, the unlocking lever 410 compresses the second elastic element 420. When the unlocking key leaves the unlocking lever 410, the second elastic element 420 provides an elastic restoring force to the unlocking lever 410, causing the unlocking lever 410 to separate from the sliding bushing 324. The second elastic element 420 is a spring. In this embodiment, when the special unlocking key leaves the unlocking lever 410, the second elastic element 420 pushes the unlocking lever 410 upward, and the unlocking lever 410 no longer contacts the sliding bushing 324 in the latch assembly 300. The first elastic element 323 pushes the latch 310 and the sliding bushing 324 into the body 100, realizing the automatic locking function after emergency mechanical unlocking.

[0059] like Figures 11 to 13 As shown, the outer periphery of the first transmission gear 220 also includes a third boss 221, and the motor drive assembly 200 also includes a position sensor 240. During the rotation of the first transmission gear 220, the position sensor 240 can sense the position signal of the third boss 221 and send a positioning signal. The drive unit 210 can receive the positioning signal and stop driving the rotation of the first transmission gear 220. In this embodiment, the position sensor 240 includes a micro switch. When the first transmission gear 220 contacts the micro switch, it sends a stop-rotation signal to the circuit board. The circuit board receives the stop-rotation signal and controls the drive unit 210 to stop rotating. The position sensor 240 is mounted on the first transmission gear 220. When the first transmission gear 220 rotates, the position sensor 240 can sense the rotation angle of the first transmission gear 220 and send a signal to indicate whether the latch 310 is in position, ensuring accurate and reliable unlocking and locking operations, effectively improving the reliability of the system.

[0060] like Figure 2 As shown, in this embodiment, the main body 100 also includes a front cover 130 and a rear cover 140. The front cover 130 and the rear cover 140 can seal the interior of the main body 100 and provide dust protection. Figures 5 to 6 As shown, the lock body structure of the battery swapping cabinet also includes a detection component 800. The detection component 800 is located within the plug assembly 700. The detection component 800 can detect the status of the battery 600 and send a detection signal. The detection component 800 includes a Hall switch, which sends a detection signal to the control system by detecting the magnet at the bottom of the battery 600. By detecting the magnetic characteristics of the battery 600 through the Hall switch, it ensures that there are characteristic signals from the battery 600 during locking and unlocking processes, such as confirming that the battery 600 is correctly inserted or that the battery 600's status meets the locking or unlocking conditions. This prevents the battery 600 from being lost and improves anti-theft security.

[0061] like Figure 2 As shown, the lock body structure of the battery swapping cabinet also includes a plug assembly 700. The plug assembly 700 is mounted on the front cover 130 and connected between the main body 100 and the battery 600. It can also sense the status of the battery 600 through the detection component 800 and send a signal to the control system. The plug assembly 700 monitors the status of the battery 600 in real time through the detection component 800. When the battery 600 is correctly inserted, the detection component 800 sends a signal to confirm that the battery 600 is in place; in abnormal situations, it can prevent locking operations or issue an alarm.

[0062] In this embodiment, as Figure 2 As shown, the plug assembly 700 also includes: a male plug housing 710, a reed switch mounting housing 720, a pin 730, and a charging male connector assembly 740. The male plug housing 710 is mounted on the front cover 130 and is used to secure and protect the other parts of the plug assembly 700. The reed switch mounting housing 720 is used to mount a Hall switch; the reed switch mounting housing 720 is fixed inside the male plug housing 710 and fits tightly with the Hall switch, providing protection and support. The pin 730 is mounted on the male plug housing 710. When the battery 600 is inserted into the battery compartment, the pin 730 guides the battery 600 into the correct position by inserting into the bottom cover of the battery 600, thus guiding the battery 600 and securing it to prevent loosening. The charging male connector assembly 740 is mounted on the male plug housing 710 and connects to the charging port at the battery 600 end for charging the battery 600, achieving electrical connection and charging functions.

[0063] The following describes the locking and unlocking processes of the lock body structure of the battery swapping cabinet.

[0064] When the battery 600 is pushed into the battery compartment of the battery swapping cabinet 500, the battery 600 contacts the latch 310, and the latch assembly 300 locks the battery 600 under the action of the first elastic element 323. At this time, the guide ball 3222 is located in the slot 3211 of the conversion cam 321, and the guide element 322 presses against the latch 310 to ensure that the battery 600 is fixed and realize the locking function.

[0065] In motor unlocking mode, when the control system receives an unlocking signal, the drive unit 210 starts, drives the first transmission gear 220 to rotate, the first transmission gear 220 then drives the second transmission gear 230 to rotate, the second transmission gear 230 drives the latch transmission unit 320 to move, the conversion cam 321 pushes the guide ball 3222 to be outside the slot 3211, the guide 322 pushes the latch 310 to move towards the outside of the mounting base 330, the latch 310 disengages from the battery 600, and electronic unlocking is achieved.

[0066] When the first transmission gear 220 rotates to a certain angle, it contacts the micro switch. The micro switch sends a stop signal to the drive unit 210 to the circuit board. The circuit board receives the stop signal and controls the drive unit 210 to stop rotating. The reset member 232 provides a springback force to the second transmission gear 230, and the locking assembly 300 returns to the initial locked state.

[0067] The design of the motor drive component 200 facilitates automated unlocking and locking of the motor, eliminating manual intervention and improving operational convenience and efficiency. After unlocking, the reset component 232 automatically restores the latch 310 to the locked state, preventing forgetting to lock or leaving it in the unlocked state for an extended period, thus increasing anti-theft security.

[0068] In the emergency mechanical unlocking mode, the unlocking lever 410 is pushed by a special unlocking key, causing the inclined surface 411 of the unlocking lever 410 to contact the sliding bushing 324. The sliding bushing 324 drives the latch 310 to move outward from the mounting base 330 within the sliding hole 120, disengaging the latch 310 from the battery 600, thus achieving emergency mechanical unlocking. After unlocking is completed, when the special unlocking key disengages from the unlocking lever 410, the second elastic element 420 pushes the unlocking lever 410 back to its original position, and the latch assembly 300 returns to the initial locked state.

[0069] By incorporating a mechanical unlocking component 400, in the event of a power outage or system malfunction, the battery swapping cabinet 500 can be mechanically unlocked via the unlocking lever 410. This avoids the problem of being unable to remove the battery 600 when the cabinet is powered off, thus increasing the safety and reliability of the cabinet. After unlocking, the cooperation between the second elastic element 420 and the first elastic element 323 facilitates the automatic reset of the locking component 300 and relocks the battery 600. This invention features a simple structure and convenient operation, making it suitable for the improvement and application of various battery swapping cabinets 500.
