The locking module 200 is arranged in the main body 100, and the locking module 200 is used to lock or unlock the batteries 800 in the battery replacement cabinet. The locking module 200 has a first state of locking the batteries 800 and a second state of unlocking the batteries 800. The motor driving assembly 300 and the mechanical unlocking assembly 400 are both arranged in the main body 100, and both can drive the locking module 200 to switch from the first state to the second state.

[0041] As shown in Figure 6 The motor driving assembly 300 comprises a driving part 310, a transmission assembly 320 and a sensor 330, and the driving part 310 can drive the transmission assembly 320 to rotate. As shown in Figure 1As shown, the transmission assembly 320 comprises a first transmission wheel 321, a second transmission wheel 322 and a reduction gear 323 which are engaged with each other. The first transmission wheel 321 is connected with the driving part 310, and the first transmission wheel 321, the reduction gear 323 and the second transmission wheel 322 are drivingly connected to realize speed reduction and torque increase. Figures 6 to 7 As shown, the second transmission wheel 322 can trigger the sensor 330. Preferably, the sensor 330 is a micro switch for detecting the position of the rotation of the second transmission wheel 322, so as to control the start and stop of the driving part 310. An O-ring is used for sealing between the second transmission wheel 322 and the lower shell 120.

[0042] As shown, Figure 1 As shown, the second transmission wheel 322 comprises a wheel body 3221, a protruding tooth structure 3223 and a protruding structure 3224. The wheel body 3221 comprises an eccentric column 3222 which can drive the locking module 200 to switch between the first state and the second state. The protruding tooth structure 3223 is arranged on the outer periphery of the wheel body 3221, and the second transmission wheel 322 is engagedly connected with the first transmission wheel 321 through the protruding tooth structure 3223. The protruding structure 3224 is located outside the protruding tooth structure 3223, and as shown, Figures 6 to 7 As shown, the protruding structure 3224 can trigger the sensor 330 to make the sensor 330 send a to-position signal, and the driving part 310 receives the to-position signal and stops driving the first transmission wheel 321 to rotate.

[0043] In the embodiment, the battery position detection module 500 can sense the access state of the battery 800 and send an access signal, and the driving part 310 can receive the access signal and drive the transmission assembly 320 to rotate. The locking detection module 600 can detect the state of the locking part 210 of the locking module 200 and send an action signal to jointly judge with the sensor whether the battery is locked or unlocked. Preferably, the battery position detection module 500 and the locking detection module 600 are dry reed tubes respectively. As shown, Figure 2 As shown, the locking detection module 600 further comprises a magnetic steel 610 which can feedback the position of the locking part 210 to the locking detection module 600.

[0044] The technical scheme of the present application sets the locking module 200 in the battery unlocking and locking device, the locking module 200 can be separated from the battery 800 or connected with the battery 800 to unlock or lock the battery 800, the locking module 200 has a first state of locking the battery 800 and a second state of unlocking the battery 800, and by setting the locking module 200 to directly lock the battery 800, the locking does not need a key, and the battery 800 is directly pushed into the locking module 200 to complete the locking by buckling the battery 800 with the locking module 200, so that the operation is convenient.

[0045] By setting the battery position detection module 500, the access state of the battery 800 can be sensed and an access signal is sent out. By setting the locking detection module 600, the state of the locking part 210 of the locking module 200 can be detected and an action signal is sent out to jointly determine with the sensor whether the battery is locked or unlocked. According to the signals fed back by the battery position detection module 500 and the locking detection module 600, it is comprehensively determined whether the battery 800 is locked or unlocked, the accuracy of the state determination of the battery 800 is improved, and the phenomenon of "false locking" that the locking part 210 fails to return to the locking position is avoided, the anti-theft capability of the battery 800 is further improved, and the battery 800 does not need to be pushed in after the battery exchange cabinet door is opened, the operation is more convenient, and the efficiency is higher.

[0046] By setting the mechanical unlocking assembly 400, under the action of an external force, the mechanical unlocking assembly 400 can be actuated to drive the locking module 200 to move, so that the locking module 200 is separated from the battery 800, and the battery 800 in the battery exchange cabinet is mechanically unlocked. This is beneficial to realize the emergency unlocking function of the battery exchange cabinet in a power-off state, and the user can also smoothly take out the battery 800 in a power-off state.

[0047] By setting the motor driving assembly 300, when it is necessary to unlock the new battery 800 in the battery exchange cabinet, the battery position detection module 500 can sense the access state of the battery 800 and send out an access signal. The driving part 310 can receive the access signal and drive the transmission assembly 320 to rotate. The second transmission wheel 322 can trigger the sensor 330 to make the sensor 330 send a to-position signal. The driving part 310 receives the to-position signal and stops driving the transmission assembly 320 to rotate. The motor driving assembly 300 can drive the locking module 200 to switch from the first state to the second state to unlock the new battery 800. This is beneficial to realize motor automatic unlocking and locking operation, avoids manual intervention, and improves the convenience and efficiency of operation. In this embodiment, the driving part 310 includes a motor.

[0048] In this embodiment, as shown in Figure 1 The main body 100 further includes an upper cover 110, a lower cover 120, a sealing gasket 130, and a wire protection ring 140. The upper cover 110 and the lower cover 120 can close the inside of the main body 100 and play a dustproof role. The upper cover 110 is used to isolate the electronic component compartment from the outside. The sealing gasket 130 is arranged between the upper cover 110 and the lower cover 120 and is used to seal the inside of the main body 100. The wire protection ring 140 is used to protect the wires in the main body 100.

[0049] As shown in Figure 1 The locking module 200 is arranged in the lower shell 120. As shown in Figure 2As shown, the locking module 200 further comprises a locking portion 210 for locking or unlocking the battery 800, a pushing portion 220, and a first elastic member 230. The pushing portion 220 is connected with the locking portion 210, the eccentric column 3222, and the mechanical unlocking assembly 400, and can drive the locking portion 210 to move to lock or unlock the battery 800. The first elastic member 230 is connected with the locking portion 210 and provides elastic restoring force for the movement of the locking portion 210. Preferably, the first elastic member 230 is a torsion spring, which can provide good elastic restoring force.

[0050] Preferably, as Figures 3 to 5 As shown, the locking module 200 further comprises a shaft sleeve 250 for connecting the pushing portion 220 and the locking portion 210, so that the contact surface of the locking portion 210 and the pushing portion 220 is in rolling contact, which is beneficial to reduce the friction. A gasket 260 can also be arranged between the locking portion 210 and the lower shell 120 to reduce the contact area of the locking portion 210 and the lower shell 120, which is beneficial to reduce the friction.

[0051] As Figures 3 to 5 As shown, the locking portion 210 is in the form of a barb, which is beneficial to avoid the situation as Figure 5 As shown, the locking portion 210 and the battery 800 are not securely engaged due to machining and assembly errors, as Figure 3 As shown, the locking portion 210 and the battery 800 form an included angle A, and the included angle is 0° to 10°, so that the locking of the locking portion 210 and the battery 800 is more secure.

[0052] As Figures 1 to 2 As shown, the locking module 200 further comprises a positioning pin 240. The positioning pin 240 is arranged on one side of the locking module 200, and the positioning pin 240 provides guiding and positioning functions for the battery 800 when the battery 800 is inserted.

[0053] As Figure 2 As shown, the mechanical unlocking assembly 400 comprises an unlocking tab 410, a guide portion 430, and a second elastic member 420. As Figures 8 to 9 As shown, under the action of an external force, the unlocking tab 410 can move the pushing portion 220 through the guide portion 430, so that the pushing portion 220 can drive the locking portion 210 to move. The second elastic member 420 is arranged in the guide portion 430, and under the action of an external force, the unlocking tab 410 is actuated and the second elastic member 420 is compressed. When the external force is removed from the unlocking tab 410, the second elastic member 420 can provide elastic restoring force for the movement of the unlocking tab 410. Preferably, the second elastic member 420 is a spring, which can provide good elastic restoring force for the unlocking tab 410.

[0054] As Figures 3 to 5As shown, the pushing part 220 includes a first guide channel 231 and a second guide channel 232 which are arranged to avoid each other, the eccentric column 3222 drives the locking part 210 to move through the first guide channel 231, and the guide part 430 of the unlocking tab 410 drives the locking part 210 to move through the second guide channel 232.

[0055] In this embodiment, after the unlocking jig is used to push the unlocking tab 410, the unlocking tab 410 can drive the guide part 430 to push the pushing part 220 to move along the second guide channel 232 by extruding the second elastic member 420, so that the pushing part 220 can drive the locking part 210 to move to unlock the battery 800, thereby realizing the emergency mechanical unlocking function. In other embodiments, the unlocking tab 410 can also be actuated in other ways, and the application does not limit the form of the unlocking tab 410. It can be a specially designed unlocking key, or it can be a common tab, or it can be manually actuated by the operator directly with the fingers. As long as the unlocking tab 410 can be actuated, the emergency mechanical unlocking can be realized. In the case of power failure or system failure of the battery replacement cabinet, it is more convenient for the user to actuate the mechanical unlocking assembly 400 to mechanically unlock the battery 800 in the battery replacement cabinet, thereby improving the user experience.

[0056] When the unlocking jig leaves the unlocking tab 410, the second elastic member 420 can provide elastic restoring force for the unlocking tab 410, and the second elastic member 420 will reset the unlocking tab 410. The unlocking tab 410 is no longer in contact with the locking part 210, and the locking part 210 returns to the locked position, thereby realizing the automatic locking function after the emergency mechanical unlocking.

[0057] As shown in Figure 1 The battery replacement cabinet unlocking and locking device also includes a plug assembly 700 connected to the battery 800. The plug assembly 700 is arranged in the main body 100, and the plug assembly 700 is arranged integrally with the locking module 200. In the state of ensuring that the locking module 200 has been locked, it is beneficial to prevent the plug assembly 700 from being in contact with the socket due to external force impact and loosening or loosening, thereby preventing the problem of poor charging contact caused by power interruption.

[0058] Next, the specific unlocking and locking process of the battery replacement cabinet unlocking and locking device will be described.

[0059] When the new battery 800 in the battery swap cabinet needs to be unlocked, the battery position detection module 500 detects that the old battery 800 is in place and sends an access signal, and the driving part 310 receives the access signal to start rotating. The driving part 310 drives the first transmission wheel 321 to rotate, the first transmission wheel 321 drives the speed reduction gear 323 to rotate, thereby driving the second transmission wheel 322 to rotate, the eccentric column 3222 of the second transmission wheel 322 contacts the first guide channel 231 on the pushing part 220, the pushing part 220 moves upward, and the locking part 210 opens. When the protruding structure 3224 on the second transmission wheel 322 contacts the sensor 330, a to-position signal is sent, the driving part 310 receives the to-position signal and stops driving the transmission assembly 320 to rotate, and the locking part 210 stops at the unlocking position. The battery swap cabinet unlocking and locking device realizes unlocking of the new battery 800.

[0060] After the new battery 800 is taken out, the battery position detection module 500 detects that the new battery 800 has been taken out, the driving part 310 receives the instruction to start rotating, the driving part 310 drives the first transmission wheel 321 to rotate, the first transmission wheel 321 drives the speed reduction gear 323 to rotate, thereby driving the second transmission wheel 322 to rotate, the eccentric column 3222 on the second transmission wheel 322 contacts the first guide channel 231 on the pushing part 220, the pushing part 220 moves downward, the first elastic member 230 resets the locking part 210, and when the protruding structure 3224 on the second transmission wheel 322 is separated from the sensor 330, the driving part 310 receives the instruction to stop rotating, and the locking part 210 stops at the locking position.

[0061] When the old battery 800 is replaced, the old battery 800 is pushed into the battery 800 compartment of the battery swap cabinet along the preset channel, and the positioning pin 240 on the locking module 200 guides the old battery 800 to the appropriate position. When the old battery 800 contacts the locking part 210, the locking part 210 is supported by the locking part 210, and when the old battery 800 passes through the locking part 210, the locking part 210 is reset under the action of the first elastic member 230. The locking part 210 locks the old battery 800, realizing the locking of the old battery 800. The battery position detection module 500 detects whether the old battery 800 is in place, the locking detection module 600 detects the state of the locking part 210 and sends an action signal, and the battery 800 is locked or unlocked according to the signals fed back by the battery position detection module 500 and the locking detection module 600.

[0062] When emergency mechanical unlocking is needed, the front door of the battery swap cabinet is opened, and a specific tool is used to pull the unlocking tab 410, which will push the locking part 210 to move to the unlocked state, realizing the mechanical unlocking of the locking module 200. When the external force acting on the unlocking tab 410 is removed, the second elastic member 420 will reset the unlocking tab 410, and the unlocking tab 410 will no longer be in contact with the locking part 210, and the locking part 210 will return to the locking position.

[0063] As shown in Figure 10 The present application also provides a battery swap cabinet unlocking and locking method, which is applied to the battery swap cabinet unlocking and locking device of any of the preceding embodiments. The battery swap cabinet unlocking and locking method comprises:

[0064] The battery position detection module 500 detects the storage state of the inserted old battery 800 and obtains a storage signal, and the locking detection module 600 detects the state of the locking part 210. Based on the storage signal and the action signal, it is determined whether the old battery 800 is inserted and located at the preset position of the battery swap cabinet.

[0065] If it is determined that the old battery 800 is inserted and located at the preset position of the battery swap cabinet, the control driving part 310 drives the transmission assembly 320 to rotate, the transmission assembly 320 drives the locking module 200 to move, the second transmission wheel 322 triggers the sensor 330 to make the sensor 330 send a to-position signal, and the driving part 310 receives the to-position signal and stops driving the transmission assembly 320 to rotate, and the locking module 200 unlocks the new battery 800.

[0066] The battery position detection module 500 detects the taking state of the new battery 800 and obtains a taking signal. Based on the taking signal, the control driving part 310 drives the transmission assembly 320 to rotate, the transmission assembly 320 drives the locking module 200 to reset, the second transmission wheel 322 leaves the sensor 330, the driving part 310 stops driving the transmission assembly 320, and the locking module 200 is locked.

[0067] The technical scheme of the present application can sense the storage and taking state of the battery 800 and send a storage and taking signal by setting the battery position detection module 500, can detect the state of the locking part 210 of the locking module 200 and send an action signal by setting the locking detection module 600, can comprehensively determine whether the battery 800 is locked or unlocked according to the signals fed back by the battery position detection module 500 and the locking detection module 600, can improve the accuracy of the locking or unlocking state determination of the battery 800, can avoid the phenomenon of "false locking" that the locking part 210 fails to return to the locking position, can further improve the anti-theft capability of the battery 800, and can push the battery 800 without waiting for the battery swap cabinet door to be opened, which is more convenient and efficient.

[0068] As shown in Figure 11As shown, the battery replacement cabinet unlocking and locking method further comprises a step of preventing false locking. Based on the storage signal and the action signal, it is determined whether the old battery 800 is inserted and located at the preset position of the battery replacement cabinet, comprising: if the battery position detection module 500 detects that the battery 800 is inserted, and the locking detection module 600 detects that the state of the locking part 210 is the action signal of closing-opening-closing, it is determined that the old battery 800 is inserted and located at the preset position of the battery replacement cabinet.

[0069] The technical scheme of the present application is advantageous to solve the problem that although the battery replacement cabinet detects that the old battery 800 is returned, the locking part 210 fails to reset to the locking state with the old battery 800 buckle, at this time the old battery 800 is in an unlocked state, the old battery 800 can still be pulled out, but the control system sends a signal that the battery 800 is locked, at this time the user can take away the new and old batteries 800 at the same time, thereby causing the problem of battery 800 theft. By setting the locking detection module 600, the state of the locking module 200 can be detected and an action signal can be sent to jointly determine whether the battery is locked or unlocked with the sensor, according to the signals fed back by the battery position detection module 500 and the locking detection module 600, it is determined whether the battery 800 is locked or unlocked, the accuracy of the battery 800 locking or unlocking state determination is improved, thereby avoiding the phenomenon of "false locking" that the locking part 210 fails to return to the locking position, and further improving the anti-theft capability of the battery 800. The plug assembly 700 is integrally arranged with the locking module 200, which is advantageous to prevent the plug assembly 700 from being loose or detached due to external force collision with the socket under the condition of ensuring that the locking module 200 is locked, thereby being advantageous to avoid the problem of poor charging contact caused by power supply interruption. Without waiting for the battery replacement cabinet door to open to push in the battery 800, the operation is more convenient and efficient. Under the action of external force, the mechanical unlocking assembly 400 can be actuated to move the locking module 200, so that the locking module 200 is separated from the battery 800, and the battery 800 in the battery replacement cabinet is mechanically unlocked, which is advantageous to realize the emergency unlocking function of the battery replacement cabinet in the power-off state, and the user can also smoothly take out the battery 800 in the power-off state.
