[0040] An embodiment of the present invention provides a lock body structure for a power exchange cabinet, which can be beneficial to improving the anti-theft effect of the power exchange cabinet, has high locking efficiency, and is conducive to realizing an emergency unlocking function in a power-off state.

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

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

[0043] like Figure 2 As shown, the lock assembly 300 is disposed in the main body 100, and the lock assembly 300 is used to lock the battery 600 in the power exchange cabinet 500. The lock assembly 300 has a first state of locking the battery 600 and a second state of unlocking the battery 600. The lock assembly 300 includes a lock 310 and a lock transmission part 320 capable of driving the lock 310 to move. In this embodiment, as Figure 3 to Figure 4 As shown, the lock structure includes two sets of locking components 300 arranged opposite to each other. The two sets of locking components 300 are respectively abutted against or separated 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 arranged in the main body 100, and the motor drive assembly 200 includes a driving part 210 and a first transmission gear 220. The driving part 210 can drive the first transmission gear 220 to rotate, and the lock transmission part 320 is connected to the first transmission gear 220. In this embodiment, the driving part 210 includes a motor, and the motor drive assembly 200 also includes a circuit board. The circuit board is electrically connected to the driving part 210, and the circuit board controls the stop and rotation of the driving part 210 through a signal. The motor drive assembly 200 also includes a driving part bracket 250, and the driving part bracket 250 installs the driving part 210 in the main body 100. When the driving part 210 receives an unlocking instruction, the driving part 210 drives the first transmission gear 220 to rotate, thereby driving the movement of the lock assembly 300 to unlock the battery 600.

[0045] like Figure 2 As shown, the mechanical unlocking assembly 400 is disposed in the main body 100 , and the unlocking key can move the mechanical unlocking assembly 400 so that the mechanical unlocking assembly 400 can drive the lock transmission part 320 to move.

[0046] In this embodiment, the motor drive assembly 200 and the mechanical unlocking assembly 400 can both drive the lock assembly 300 to switch from the first state to the second state. Figures 5 and 6 As shown, when the motor drive assembly 200 drives the lock assembly 300 to switch from the first state to the second state, the lock body structure is in the electronic unlocking mode, and the drive unit 210 drives the first transmission gear 220 and the lock transmission unit 320 to move in sequence, so that the lock 310 extends out and separates from the battery 600 to unlock the battery 600 in the power exchange cabinet 500; Figure 7 As shown, when the mechanical unlocking component 400 drives the lock component 300 to switch from the first state to the second state, the lock body structure is in the mechanical unlocking mode, and the mechanical unlocking component 400 drives the lock transmission part 320 to move, so that the lock 310 extends and separates from the battery 600 to unlock the battery 600 in the power exchange cabinet 500. By setting the mechanical unlocking component 400, it is beneficial to realize the emergency unlocking function of the power exchange cabinet 500 in the power-off state, and the user can also smoothly remove the battery 600 in the power-off state.

[0047] The technical solution of the present invention is to set a lock assembly 300 and a mechanical unlocking assembly 400 in the lock body structure of the power exchange cabinet. The lock assembly 300 includes a lock 310 and a lock transmission part 320. The lock transmission part 320 can drive the lock 310 to move. Figure 3 to Figure 4As shown, when the lock buckle 310 retracts inward, the lock buckle 310 contacts the bottom cover of the battery 600 to fasten the battery 600, thus realizing the locking function; when the lock buckle 310 extends outward, the bottom cover of the battery 600 no longer contacts the lock buckle 310, and the lock buckle 310 unlocks the battery 600, so that the battery 600 can enter and exit freely, thus realizing the unlocking function. By setting the lock buckle 310 to directly lock the battery 600, no key is required for locking, and the battery 600 can be directly pushed in after the battery replacement is completed to complete the locking, which is convenient to operate and helps to avoid the situation where a fake door lock is inserted into the battery replacement cabinet 500, or the door is falsely closed so that the system receives a false door closing signal, thereby causing the battery 600 to be stolen, and also helps to avoid the situation where the battery 600 is stolen due to forgetting to close the door after the battery replacement.

[0048] like Figure 8 As shown, the lock assembly 300 includes a mounting seat 330, the lock 310 is mounted on the mounting seat 330, and the lock transmission part 320 can slide in the mounting seat 330. Figure 1 As shown, the lock 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, and the conversion cam 321 is installed in the mounting hole. The conversion cam 321 moves synchronously with the first transmission gear 220. Figures 9 and 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 transmission-connected with the conversion cam 321. Figure 8 As shown, the guide member 322 is connected to the lock buckle 310 in a transmission manner along the first direction S1. The guide member 322 includes: a guide pin 3221 and a guide ball 3222. Figures 9 and 10 As shown, the guide ball 3222 is arranged in contact with the guide pin 3221, and the conversion cam 321 rotates so that the guide ball 3222 can be located in or out of the slot 3211, and the guide ball 3222 can drive the guide pin 3221 to slide. By changing the position of the guide ball 3222 in the slot 3211 or outside the slot 3211, the locking and unlocking states of the lock body structure are changed, and the automatic unlocking and locking of the lock assembly 300 is realized. When the guide ball 3222 is in the slot 3211 of the conversion cam 321, the first elastic member 323 pushes the lock buckle 310 into the main body 100, and the lock buckle 310 is in the locked state; when the guide ball 3222 is outside the slot 3211 of the cam, that is, the guide ball 3222 contacts the sliding surface 3212 of the cam, the guide ball 3222 pushes the lock buckle 310 out of the main body 100 through the guide pin 3221, and the lock buckle 310 is in the unlocked state.

[0049] like Figure 8As shown, the first elastic member 323 is connected to the lock buckle 310, and the first elastic member 323 can provide elastic restoring force for the lock buckle 310 to switch from the second state to the first state, and the first elastic member 323 is a spring. Figures 9 and 10 As shown, in the unlocked state, the guide ball 3222 leaves the slot 3211, and the guide pin 3221 drives the lock buckle 310 to move and squeeze the first elastic member 323, so that the lock buckle 310 is separated from the battery 600 to unlock the battery 600 in the power exchange cabinet 500. By rotating the conversion cam 321, the guide member 322 is located in the slot 3211 or contacts the sliding surface 3212, thereby pushing the lock buckle 310 out of the battery 600 or abutting against the battery 600, realizing the unlocking and locking functions.

[0050] like Figure 2 As shown, the main body 100 further includes a sliding hole 120, and the lock transmission part 320 further includes a sliding sleeve 324. Figure 8 As shown, the sliding sleeve 324 installs the lock buckle 310 on the sliding hole 120 along the second direction S2, and the sliding hole 120 is a waist-shaped hole. In the mechanical unlocking mode, the unlocking key toggles the mechanical unlocking assembly 400 so that the mechanical unlocking assembly 400 contacts the sliding sleeve 324 and can drive the sliding sleeve 324 to move, and the sliding sleeve 324 can drive the lock buckle 310 to move in the sliding hole 120. In this embodiment, the mounting seat 330 also includes a fourth boss 331, and the sliding sleeve 324 is installed on the fourth boss 331. The sliding sleeve 324 and the lock buckle 310 move simultaneously. The sliding sleeve 324 is an oil-containing bearing, which can not only limit the lock buckle 310 to reduce friction and wear, but also facilitate the lock buckle 310 to move along the guide direction of the guide pin 3221, avoiding the lock buckle 310 from deviating or getting stuck, and enhancing the stability and reliability of the movement of the lock buckle 310, thereby improving the response speed and efficiency of the lock body structure. In this embodiment, as Figure 2 As shown, the locking assembly 300 further includes: a first blocking cover 340 , which can close the sliding hole 120 and limit the sliding sleeve 324 .

[0051] In this embodiment, if Figure 2 As shown, the lock assembly 300 also includes a second blocking cover 350, and the first elastic member 323 is installed on the second blocking cover 350. The second blocking cover 350 seals the inside of the lock assembly 300, limits the position of the first elastic member 323, and prevents the automatic locking function of the lock assembly 300 from failing due to the first elastic member 323 being displaced and popped out. When the sliding sleeve 324 is driven by the mechanical unlocking assembly 400 and is located at the outer limit position of the main body 100, the first elastic member 323 is in a compressed state and accumulates force; when the sliding sleeve 324 is at the inner limit position of the main body 100, the first elastic member 323 pushes the lock 310 toward the mounting seat 330, realizing the automatic locking function of the lock 310.

[0052] like Figures 11 to 13 As shown, the main body 100 further includes a first boss 110, and the motor drive assembly 200 further includes: a second transmission gear 230, the first transmission gear 220, the second transmission gear 230, and the conversion cam 321 can be transmission-connected, and 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 a plurality of second bosses 231, and 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 the unlocking and locking modes. The second transmission gear 230 is limited by the mutual cooperation between the first boss 110 and the second boss 231, and the second transmission gear 230 can be meshed and connected 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 further includes: a protective cover 260 , which can protect the cooperation 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 the first transmission gear 220 and the second transmission gear 230 .

[0054] like Figure 2 As shown, a reset member 232 is also provided on the second transmission gear 230. In the motor unlocking mode, the first transmission gear 220 is meshed and connected with the second transmission gear 230, 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 separated, the reset member 232 can provide elastic restoring force for the second transmission gear 230. The reset member 232 is a reset torsion spring.

[0055] In this embodiment, the reset member 232 is installed on the second transmission gear 230. When the first transmission gear 220 and the second transmission gear 230 mesh and rotate, the reset member 232 enters a power storage state. After the unlocking is completed, when the first transmission gear 220 and the second transmission gear 230 are no longer in contact with each other, the reset member 232 releases the elastic force, drives the second transmission gear 230 to rotate, and makes the second transmission gear 230 rebound, thereby driving the lock catch 310 to re-lock the battery 600 and realize automatic locking. When the first boss 110 touches the second boss 231, the second transmission gear 230 stops rebounding. 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 matching design of the first transmission gear 220 and the second transmission gear 230 ensures that the second transmission gear 230 will automatically return to the initial position after each unlocking, avoiding the tooth-breaking phenomenon and improving the reliability of the locking.

[0056] In addition, the lock structure also has the function of delayed automatic locking after unlocking, ensuring that there is enough time to remove the battery 600 after unlocking. The time of delayed automatic locking depends on the power storage degree of the reset member 232 and the second transmission gear 230, and then the second transmission gear 230 automatically rebounds and locks, avoiding being in the unlocked state for a long time, ensuring that the lock structure automatically returns to the locked state after the battery 600 is removed, and improving safety.

[0057] like Figure 7 As shown, the mechanical unlocking assembly 400 includes an unlocking paddle 410, and the unlocking paddle 410 has an inclined surface 411 that can contact the sliding sleeve 324. In the mechanical unlocking mode, the inclined surface 411 can apply pressure to the sliding sleeve 324. Figure 2 As shown, the sliding sleeve 324 can push the lock 310 to move in the sliding hole 120 under the action of external force. In this embodiment, when the operator pushes the unlocking paddle 410 with the special unlocking key, the inclined surface 411 of the unlocking paddle 410 touches the sliding sleeve 324 in the lock assembly 300, and pushes the sliding sleeve 324 outward of the main body 100, thereby driving the lock 310 to extend outward, and the bottom cover of the battery 600 is no longer in contact with the lock 310, and the lock 310 unlocks the battery 600, and the battery 600 can move in and out freely, realizing the unlocking function.

[0058] like Figure 2As shown, the mechanical unlocking assembly 400 further includes a second elastic member 420. The second elastic member 420 is connected to the unlocking paddle 410. The unlocking key toggles the mechanical unlocking assembly 400 so that the unlocking paddle 410 compresses the second elastic member 420. When the unlocking key leaves the unlocking paddle 410, the second elastic member 420 can provide elastic restoring force for the unlocking paddle 410, so that the unlocking paddle 410 is separated from the sliding sleeve 324. The second elastic member 420 is a spring. In this embodiment, when the special unlocking key leaves the unlocking paddle 410, the second elastic member 420 pushes the unlocking paddle 410 upward, and the unlocking paddle 410 no longer touches the sliding sleeve 324 in the lock assembly 300. The first elastic member 323 pushes the lock 310 and the sliding sleeve 324 toward the inside of the main 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 further includes a third boss 221, and the motor drive assembly 200 further 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 position signal, and the driving unit 210 can receive the position 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, a signal to stop the rotation of the driving unit 210 is sent to the circuit board. The circuit board receives the signal to stop the rotation of the driving unit 210 and controls the driving unit 210 to stop rotating. The position sensor 240 is installed on the first transmission gear 220.

[0061] like Figure 2 As shown, the lock structure of the power exchange cabinet also includes: a plug assembly 700. The plug assembly 700 is installed on the front cover 130 and connected between the main body 100 and the battery 600. At the same time, the plug assembly 700 can sense the state of the battery 600 through the detection assembly 800 and send a signal to the control system. The plug assembly 700 monitors the state of the battery 600 in real time through the detection assembly 800. When the battery 600 is correctly inserted, the detection assembly 800 sends a signal to confirm that the battery 600 is in place; in abnormal circumstances, it can prevent the locking operation or sound an alarm.

[0062] In this embodiment, if Figure 2 As shown, the plug assembly 700 also includes: a male plug housing 710, a reed switch mounting housing 720, a plug pin 730 and a charging male plug assembly 740.

[0063] Next, the various unlocking processes of the lock body structure of the power exchange cabinet are described.

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

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

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

[0067] The design of the motor drive assembly 200 facilitates the realization of motor automatic unlocking and locking operations, avoids manual intervention, and improves the convenience and efficiency of operation. After unlocking is completed, the reset member 232 automatically restores the lock catch 310 to the locked state, preventing forgetting to lock or keeping the unlocked state for a long time, thereby increasing anti-theft security.

[0068] In the emergency mechanical unlocking mode, the unlocking paddle 410 is pushed by the special unlocking key, so that the inclined surface 411 of the unlocking paddle 410 contacts the sliding sleeve 324, and the sliding sleeve 324 drives the lock buckle 310 to move toward the outside of the mounting seat 330 in the sliding hole 120, and the lock buckle 310 is separated from the battery 600, so as to realize the emergency mechanical unlocking. After the unlocking is completed, when the special unlocking key is separated from the unlocking paddle 410, the second elastic member 420 pushes the unlocking paddle 410 and restores the unlocking paddle 410 to its original position, and the lock buckle assembly 300 returns to the initial locked state.

[0069] By setting the mechanical unlocking assembly 400, when the power exchange cabinet 500 is powered off or the system fails, the mechanical unlocking of the power exchange cabinet 500 can be achieved through the unlocking paddle 410, avoiding the problem that the battery 600 cannot be removed when the power exchange cabinet 500 is powered off, thereby increasing the safety and reliability of the power exchange cabinet 500. After unlocking, the cooperation of the second elastic member 420 and the first elastic member 323 is conducive to achieving the effect of automatically resetting the lock assembly 300 and re-locking the battery 600. The technical solution of the present invention has a simple structure and is easy to operate, and is suitable for the improvement and application of various types of power exchange cabinets 500.
