Description

Technical Field

[0001] The present invention relates to the technical field of power exchange cabinets, and in particular to a power exchange cabinet unlocking device and method. Background Art

[0002] With the widespread use of electric two-wheeled vehicles, battery swap cabinets can facilitate users to quickly replace batteries, and have gradually become important equipment for providing battery replacement services. In order to ensure the safety of battery access and the convenience of operation, battery swap cabinets are usually equipped with unlocking devices for locking or unlocking batteries. However, the control accuracy and reliability of the unlocking device in the prior art are low, and it is easy for the battery swap cabinet to detect the return of the old battery, but the lock fails to connect with the old battery and reset to the locked state. At this time, the old battery is in an unlocked state and can still be pulled out, but the control system sends a signal that the battery has been locked. At this time, the user may be able to take away both the new and old batteries at the same time, resulting in battery theft. Summary of the invention

[0039] The embodiments of the present invention provide a battery swap cabinet unlocking device and method, which can help improve the anti-theft effect of the battery swap cabinet and help avoid the problem of battery theft.

[0040] like Figures 1 to 5 As shown, an embodiment of the present invention provides a power exchange cabinet unlocking device. The power exchange cabinet unlocking device includes: a main body 100, a locking module 200, a motor drive assembly 300 and a mechanical unlocking assembly 400, a battery position detection module 500 and a locking detection module 600. The locking module 200 is arranged in the main body 100, and the locking module 200 is used to lock or unlock the battery 800 in the power exchange cabinet. The locking module 200 has a first state of locking the battery 800 and a second state of unlocking the battery 800. The motor drive 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] like Figure 6 As shown, the motor drive assembly 300 includes a drive unit 310, a transmission assembly 320 and a sensor 330. The drive unit 310 can drive the transmission assembly 320 to rotate. Figure 1As shown, the transmission assembly 320 includes a first transmission wheel 321, a second transmission wheel 322 and a reduction gear 323 that mesh with each other. The first transmission wheel 321 is connected to the driving part 310, and the first transmission wheel 321, the reduction gear 323 and the second transmission wheel 322 are in transmission connection to achieve speed reduction and torque increase. Figure 6 to Figure 7 As shown, the second transmission wheel 322 can trigger the sensor 330. Preferably, the sensor 330 is a micro switch for detecting the rotation position of the second transmission wheel 322, thereby controlling the start and stop of the driving part 310. The O-ring is used for sealing between the second transmission wheel 322 and the lower shell 120.

[0042] like Figure 1 As shown, the second transmission wheel 322 includes: a wheel body 3221, a convex tooth structure 3223 and a protruding structure 3224. The wheel body 3221 includes an eccentric column 3222, and the eccentric column 3222 can drive the locking module 200 to switch between the first state and the second state. The convex tooth structure 3223 is arranged on the outer periphery of the wheel body 3221, and the second transmission wheel 322 is meshed and connected with the first transmission wheel 321 through the convex tooth structure 3223. The protruding structure 3224 is located outside the convex tooth structure 3223, as shown in FIG. Figure 6 to Figure 7 As shown, the protruding structure 3224 can trigger the sensor 330 so that the sensor 330 sends a position signal, and the driving part 310 receives the position signal and stops driving the first transmission wheel 321 to rotate.

[0043] In this embodiment, the battery position detection module 500 can sense the access status of the battery 800 and send an access signal, and the driving unit 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 unit 210 of the locking module 200 and send an action signal to determine whether the battery is locked or unlocked together with the sensor. Preferably, the battery position detection module 500 and the locking detection module 600 are reed switches. Figure 2 As shown, the locking detection module 600 further includes a magnet 610 , and the magnet 610 can feed back the position of the locking portion 210 to the locking detection module 600 .

[0044] The technical solution of the present invention is to set a locking module 200 in the unlocking device of the battery exchange cabinet. The locking module 200 can be separated from or connected to the battery 800 to unlock or lock the battery 800. The locking module 200 has a first state for locking the battery 800 and a second state for unlocking the battery 800. The battery 800 is directly locked by setting the locking module 200. No key is required for locking. The battery 800 can be directly pushed in, so that the battery 800 can be locked by snapping into the locking module 200. The operation is convenient.

[0045] By setting a battery position detection module 500 that can sense the access status of the battery 800 and send an access signal, and setting a locking detection module 600 that can detect the status of the locking part 210 of the locking module 200 and send an action signal to jointly determine whether the battery is locked or unlocked with the sensor, it is comprehensively judged whether the battery 800 is locked or unlocked based on the signals fed back by both the battery position detection module 500 and the locking detection module 600, thereby improving the accuracy of the judgment of the locked or unlocked status of the battery 800, thereby avoiding the phenomenon of "false locking" such as the locking part 210 failing to return to the locked position, further improving the anti-theft capability of the battery 800, and there is no need to wait for the battery exchange cabinet door to be opened before pushing the battery 800, so the operation is more convenient and more efficient.

[0046] By setting up a mechanical unlocking component 400, the mechanical unlocking component 400 can be pushed under the action of external force so that the mechanical unlocking component 400 can drive the locking module 200 to move, so that the locking module 200 is separated from the battery 800, so as to mechanically unlock the battery 800 in the power exchange cabinet, which is conducive to realizing the emergency unlocking function of the power exchange cabinet when the power is off, and the user can also smoothly remove the battery 800 when the power is off.

[0047] By setting the motor drive 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 status of the battery 800 and send an access signal, the drive unit 310 can receive the access signal and drive the transmission assembly 320 to rotate, the second transmission wheel 322 can trigger the sensor 330 so that the sensor 330 sends a position signal, and the drive unit 310 receives the position signal and stops driving the transmission assembly 320 to rotate. The motor drive assembly 300 can drive the locking module 200 to switch from the first state to the second state to unlock the new battery 800, which is conducive to realizing the automatic unlocking and locking operation of the motor, avoiding manual intervention, and improving the convenience and efficiency of operation. In this embodiment, the drive unit 310 includes a motor.

[0048] In this embodiment, if Figure 1 As shown, the main body 100 also includes an upper cover 110, a lower cover 120, a sealing gasket 130, and a protective coil 140. The upper cover 110 and the lower cover 120 can seal the interior of the main body 100 and play a dust-proof 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 to seal the interior of the main body 100. The protective coil 140 is used to protect the wires inside the main body 100.

[0049] like Figure 1 As shown, the locking module 200 is disposed on the lower housing 120. Figure 2As shown, the locking module 200 further includes: a locking portion 210, a pushing portion 220 and a first elastic member 230 for locking or unlocking the battery 800. The pushing portion 220 is connected to 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 to the locking portion 210 and provides an 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, if Figures 3 to 5 As shown, the locking module 200 further includes a sleeve 250, which is used to connect 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 conducive to reducing friction. A gasket 260 can also be provided between the locking portion 210 and the lower shell 120 to reduce the contact area between the locking portion 210 and the lower shell 120, which is conducive to reducing friction.

[0051] like Figures 3 to 5 As shown, the locking portion 210 is a barbed hook structure, which is helpful to avoid Figure 5 As shown, due to processing and assembly errors, the locking portion 210 and the battery 800 are not firmly engaged. Figure 3 As shown, the locking surfaces between the locking portion 210 and the battery 800 form an angle A, which is 0° to 10°, so that the locking portion 210 and the battery 800 are locked more securely.

[0052] like Figure 1 to Figure 2 As shown, the locking module 200 further includes a positioning pin 240. The positioning pin 240 is disposed on one side of the locking module 200, and the positioning pin 240 provides guidance and positioning for the battery 800 when the battery 800 is inserted.

[0053] like Figure 2 As shown, the mechanical unlocking assembly 400 includes: an unlocking paddle 410, a guide portion 430 and a second elastic member 420. Figures 8 to 9 As shown, under the action of external force, the unlocking paddle 410 can push the pushing part 220 to move through the guide part 430, so that the pushing part 220 can drive the locking part 210 to move. The second elastic member 420 is arranged on the guide part 430. Under the action of external force, the unlocking paddle 410 is pushed and the second elastic member 420 is compressed. When the external force leaves the unlocking paddle 410, the second elastic member 420 can provide elastic restoring force for the movement of the unlocking paddle 410. Preferably, the second elastic member 420 is a spring, which can provide good elastic restoring force for the unlocking paddle 410.

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

[0055] In this embodiment, when the operator uses the unlocking jig to push the unlocking paddle 410, the unlocking paddle 410 can squeeze the second elastic member 420 to drive the guide portion 430 to push the pushing portion 220 along the second guide channel 232, so that the pushing portion 220 can drive the locking portion 210 to move, so as to unlock the battery 800 and realize the emergency mechanical unlocking function. In other embodiments, other methods can also be used to toggle the unlocking paddle 410. This application does not limit the form of toggling the unlocking paddle 410. It can be a specially designed unlocking key, or an ordinary paddle, or the operator can directly manually toggle the unlocking paddle 410 with a finger. Emergency mechanical unlocking can be achieved by simply toggling the unlocking paddle 410. In the case of power failure or system failure in the power exchange cabinet, it is more convenient for users to quickly and conveniently toggle the mechanical unlocking assembly 400 to mechanically unlock the battery 800 in the power exchange cabinet, thereby improving the user experience.

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

[0057] like Figure 1 As shown, the unlocking device of the power exchange cabinet also includes a plug assembly 700 connected to the battery 800. The plug assembly 700 is arranged on the main body 100. The plug assembly 700 and the locking module 200 are integrally arranged. When the locking module 200 is ensured to be locked, it is beneficial to prevent the plug assembly 700 from loosening or coming loose from the socket due to external force collision, thereby helping to avoid the problem of poor charging contact caused by power interruption.

[0058] Next, the specific unlocking process of the unlocking device of the power swap cabinet is described.

[0059] When it is necessary to unlock the new battery 800 in the power exchange cabinet, the battery position detection module 500 detects that the old battery 800 is in place and sends an access signal, and the drive unit 310 receives the access signal and starts to rotate. The drive unit 310 drives the first transmission wheel 321 to rotate, and the rotation of the first transmission wheel 321 drives the reduction gear 323 to rotate, thereby driving the second transmission wheel 322 to rotate, and the eccentric column 3222 of the second transmission wheel 322 contacts the first guide channel 231 on the push part 220, so that the push 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, it sends a signal of arrival, and the drive unit 310 receives the signal of arrival and stops driving the transmission assembly 320 to rotate. The locking part 210 will stop at the unlocked position, and the power exchange cabinet unlocking device realizes the unlocking of the new battery 800.

[0060] After taking out the new battery 800, the battery position detection module 500 detects that the new battery 800 has been taken out, and the driving part 310 starts to rotate upon receiving the instruction, and the driving part 310 drives the first transmission wheel 321 to rotate, and the rotation of the first transmission wheel 321 drives the reduction gear 323 to rotate, thereby driving the second transmission wheel 322 to rotate, and the eccentric column 3222 on the second transmission wheel 322 contacts the first guide channel 231 on the pushing part 220, so that the pushing part 220 moves downward, and the first elastic member 230 resets the locking part 210, and when the protruding structure 3224 on the second transmission wheel 322 disengages from the sensor 330, the driving part 310 stops rotating upon receiving the instruction, and the locking part 210 stops in the locked position.

[0061] When replacing the old battery 800, push the old battery 800 into the battery 800 compartment of the power exchange cabinet along the preset channel, and the positioning pin 240 on the locking module 200 will guide the old battery 800 to a suitable position. When the old battery 800 contacts the locking part 210, the guide angle of the locking part 210 will open the locking part 210. When the old battery 800 passes through the guide angle of the locking part 210, the locking part 210 returns to the locked state under the action of the first elastic member 230, and the locking part 210 will lock the old battery 800 to achieve the locking of the old battery 800. The battery position detection module 500 detects whether the old battery 800 is in place, and the locking detection module 600 detects the state of the locking part 210 and sends an action signal. According to the signals fed back by the battery position detection module 500 and the locking detection module 600, it is comprehensively judged whether the battery 800 is locked or unlocked.

[0062] When emergency mechanical unlocking is required, open the front door of the power exchange cabinet, use a specific tool to pull the unlocking paddle 410, and the unlocking paddle 410 will push the locking part 210 to move to the unlocked state, thereby realizing the mechanical unlocking of the locking module 200. When the unlocking paddle 410 is withdrawn by external force, the second elastic member 420 will reset the unlocking paddle 410, and the unlocking paddle 410 will no longer contact the locking part 210, and the locking part 210 will return to the locked position.

[0063] like Fig.10 As shown, an embodiment of the present invention further provides a method for unlocking a power exchange cabinet, and the method for unlocking a power exchange cabinet is applied to the power exchange cabinet unlocking device of any of the aforementioned embodiments. The method for unlocking a power exchange cabinet includes:

[0064] The battery position detection module 500 detects the storage status of the inserted old battery 800 and obtains a storage signal. The locking detection module 600 detects the status of the locking part 210 and determines whether the old battery 800 is inserted and is in the preset position of the battery swap cabinet based on the storage signal and the action signal.

[0065] If it is determined that the old battery 800 is inserted and is in the preset position of the battery exchange cabinet, the control drive unit 310 drives the transmission assembly 320 to rotate, the transmission assembly 320 drives the locking module 200 to move, and the second transmission wheel 322 triggers the sensor 330 so that the sensor 330 sends an in-place signal. The drive unit 310 receives the in-place 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 removal status of the new battery 800 and obtains a removal signal. Based on the removal signal, the driving unit 310 is controlled to drive the transmission assembly 320 to rotate, and the transmission assembly 320 drives the locking module 200 to reset. The second transmission wheel 322 leaves the sensor 330, the driving unit 310 stops driving the transmission assembly 320, and the locking module 200 is locked.

[0067] The technical solution of the present invention can sense the access status of the battery 800 and send an access signal by setting a battery position detection module 500, and can detect the status of the locking part 210 of the locking module 200 and send an action signal by setting a locking detection module 600. It can comprehensively judge whether the battery 800 is locked or unlocked based on the signals fed back by both the battery position detection module 500 and the locking detection module 600, thereby improving the accuracy of judging the locked or unlocked status of the battery 800, thereby avoiding the phenomenon of "false locking" such as the locking part 210 failing to return to the locked position, further improving the anti-theft capability of the battery 800, and there is no need to wait for the battery exchange cabinet door to be opened before pushing the battery 800 in, which makes the operation more convenient and efficient.

[0068] like Fig.11As shown, the unlocking method of the power exchange cabinet also includes the step of preventing false locking. Based on the storage signal and the action signal, judging whether the old battery 800 is inserted and located at the preset position of the power exchange cabinet includes: 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 a closed-open-closed action signal, then it is judged that the old battery 800 is inserted and located at the preset position of the power exchange cabinet.

[0069] The technical solution of the present invention is conducive to solving the problem that although the battery exchange cabinet detects the return of the old battery 800, the locking part 210 fails to buckle with the old battery 800 and reset to the locked state. At this time, the old battery 800 is in an unlocked state and can still be pulled out, but the control system sends a signal that the battery 800 is locked. At this time, the user may be able to take away both the new and old batteries 800 at the same time, thereby causing the battery 800 to be stolen. By setting the locking detection module 600, it is possible to detect the state of the locking module 200 and send an action signal 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 comprehensively determined whether the battery 800 is locked or unlocked, thereby improving the accuracy of the judgment of the locked or unlocked state of the battery 800, thereby avoiding the phenomenon of "false locking" such as the locking part 210 failing to return to the locked position, and further improving the anti-theft ability of the battery 800. The plug assembly 700 is integrally arranged with the locking module 200. When the locking module 200 is locked, it is helpful to prevent the plug assembly 700 from loosening or coming loose from the socket due to external force collision, thereby helping to avoid the problem of poor charging contact caused by power interruption. There is no need to wait for the door of the power exchange cabinet to open before pushing the battery 800 in, which makes the operation more convenient and more efficient. Under the action of external force, the mechanical unlocking assembly 400 can be toggled so that the mechanical unlocking assembly 400 can drive the locking module 200 to move, so that the locking module 200 is separated from the battery 800, so as to mechanically unlock the battery 800 in the power exchange cabinet, which is conducive to realizing the emergency unlocking function of the power exchange cabinet in the power-off state, and the user can also smoothly remove the battery 800 in the power-off state.

[0070] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
