[0065] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0066] Example 1

[0067] like Figures 1 to 3FIG. 1 shows an embodiment of a battery box locking control system according to the present invention. The battery box locking control system is used to load a battery box 1 into a battery compartment 2. The battery box locking control system includes a tray pusher 3, a first controller 4, a second controller 5, and a first detection unit 6. The tray pusher 3 includes a tray pusher housing 31 and a suction cup 32. The suction cup 32 is retractably mounted on the surface of the tray pusher housing 31 and is adapted to engage with the battery box 1. The first controller 4 is adapted to drive the tray pusher 3 forward to allow the battery box 1 to enter the battery compartment 2. The second controller 5 is adapted to switch the tray pusher 3 and the battery box 1 between connected and disconnected states. The first detection unit 6 is adapted to send a first signal to the first controller 4 and the second controller 5 upon detecting that the suction cup 32 has retracted to a first predetermined position. The first controller 4 is further adapted to stop driving the tray pusher 3 forward upon receipt of the first signal. The second controller 5 is further adapted to control the tray pusher 3 to disconnect from the battery box 1 upon receipt of the first signal.

[0068] like Figure 1 As shown, the battery box 1 is placed on the platform and connected to the tray pushing box 3. The first controller 4 drives the tray pushing box 3 to move forward, thereby pushing the battery box 1 forward. Figure 2 As shown, the first controller 4 drives the disc pushing box 3 to advance until the battery box 1 enters the battery compartment 2. At this time, the disc pushing box 3 can also continue to advance, so that the suction cup 32 is retracted into the disc pushing box body 31.

[0069] The first predetermined position is set as the limit position of the suction cup 32 retraction. Figure 3 As shown, after detecting that the suction cup 32 has retracted to the first predetermined position, the first detection unit 6 sends a first signal to the first controller 4. Upon receiving the first signal, the first controller 4 stops driving the disc ejector 3 forward. The first signal from the first detection unit 6 is also sent to the second controller 5. Upon receiving the first signal, the second controller 5 controls the disc ejector 3 to separate from the battery box 1.

[0070] By providing a retractable suction cup 32 and a first detection unit 6 for detecting the limit position, the push-disc box 3 can continue to move forward and slowly stop after the battery box 1 enters the battery compartment 2, so that the push-disc box 3 has a buffer process before stopping, ensuring that the push-disc box 3 can stop smoothly and that the battery box 1 is installed in place in the battery compartment 2.

[0071] A specific method for the second controller 5 to control the tray ejector 3 to separate from the battery box 1 is as follows. The suction cup 32 is an electromagnetic suction cup, and the battery box 1 includes a magnetic disk 11. The magnetic disk 11 of the battery box 1 is configured to engage with the suction cup 32 of the tray ejector 3. The second controller 5 is configured to control the suction cup 32 to be de-energized upon receiving a first signal, thereby separating the tray ejector 3 from the battery box 1.

[0072] The first controller 4 is also used to control the disc pushing box 3 to return after stopping driving the disc pushing box 3. After the battery box 1 is installed in place in the battery compartment 2 and it is determined that the disc pushing box 3 is separated from the battery box 1, the first controller 4 controls the disc pushing box 3 to return.

[0073] The first detection unit 6 may be a sensor. The sensor's detection position is a first predetermined position. When the suction cup 32 retracts to the first predetermined position, the sensor detects the suction cup 32 and sends a first signal indicating that the suction cup 32 is in place. In addition to a sensor, the first detection unit 6 may also be another detection device capable of detecting the position of the suction cup 32.

[0074] Example 2

[0075] like Figure 4 As shown, the battery box locking control system of this embodiment is a further improvement of embodiment 1.

[0076] The battery box locking control system also includes a second detection unit 7, which is used to detect whether the disk pusher box 3 reaches the first limit position during the return process. If so, a first pause signal is sent to the first controller 4. The first controller 4 is also used to pause the return of the disk pusher box 3 after receiving the first pause signal.

[0077] The first limit position is the limit position that the disc pushing box 3 can reach during the return process. If the disc pushing box 3 reaches the first limit position, it means that an abnormality has occurred during the return process of the disc pushing box 3. The first controller 4 suspends the return of the disc pushing box 3 and enters the abnormality processing stage.

[0078] The second detection unit 7 may be a pair of an infrared receiver and an infrared transmitter. The infrared receiver is disposed on the movable platform of the disc ejector 3. The infrared receiver is located at the first extreme position during the return process of the disc ejector 3, and the infrared transmitter is disposed on the disc ejector 3. When the disc ejector 3 moves to the first extreme position, the infrared light emitted by the infrared transmitter is received by the infrared receiver. At this time, the infrared receiver sends a first pause signal to the first controller 4. When the first controller 4 receives the first pause signal, it indicates that the disc ejector 3 is at the first extreme position, indicating that an abnormality has occurred during the return process of the disc ejector 3. The first controller 4 then pauses the return of the disc ejector 3 and enters the abnormality handling stage.

[0079] Example 3

[0080] like Figures 5 and 6 As shown, the battery box locking control system of this embodiment is a further improvement of embodiment 1.

[0081] The battery box 1 further includes a lock tongue 12 and a button 13. The lock tongue 12 cooperates with the lock seat 21 of the battery compartment 2, and the button 13 is connected to the lock tongue 12. When the battery box 1 is loaded into the battery compartment 2, the lock tongue 12 of the battery box 1 is stuck in the lock seat 21 of the battery compartment 2.

[0082] like Figures 7 and 8 As shown, the disc ejector 3 further includes a push rod 33 and a third controller 34. The third controller 34 is used to control the extension and retraction of the push rod 33. The push rod 33 is used to move and reset the lock tongue 12 when the button 13 is pressed. The third controller 34 is in communication with the first controller 4. The first controller 4 is used to send a second signal to the third controller 34 when the disc ejector 3 is driven to the second predetermined position. The third controller 34 is used to control the push rod 33 to press the button 13 after receiving the second signal.

[0083] The second predetermined position is set before the battery box 1 enters the battery compartment 2. When the push tray box 3 pushes the battery box 1, the push rod 33 is controlled to press the button 13 to ensure that the lock tongue 12 is reset to the locking ready state.

[0084] Example 4

[0085] like Figure 9 As shown, the battery box locking control system of this embodiment is a further improvement of embodiment 1.

[0086] The battery box locking control system also includes a third detection unit 8, which is used to send a permission signal to the first controller 4 after detecting that the lock tongue 12 and the lock seat 21 are in a locked state. The first controller 4 is also used to determine whether the permission signal is received after stopping the advancement of the push disk box 3. If so, it controls the push disk box 3 to return.

[0087] Before the disc ejector 3 is returned, the third detection unit 8 first detects whether the lock tongue 12 and the lock seat 21 are in a locked state. Only when the lock tongue 12 and the lock seat 21 are in a locked state, that is, when the battery box 1 is properly installed in the battery compartment 2, can the disc ejector 3 be allowed to return.

[0088] The third detection unit 8 may be a sensor. When the sensor detects that the lock tongue 12 is located within the lock base 21, indicating that the lock tongue 12 and the lock base 21 are locked, the sensor sends a permission signal to the first controller 4 to allow the disk ejector 3 to return, allowing the first controller 4 to control the return of the disk ejector 3. In addition to a sensor, the third detection unit 8 may also be another detection device that can detect the position of the lock tongue 12.

[0089] Example 5

[0090] like Figure 10 As shown, the battery box locking control system of this embodiment is a further improvement of embodiment 1.

[0091] The battery box locking control system also includes a fourth detection unit 9, which is used to detect whether the disk pusher box 3 reaches the second limit position during its forward movement. If so, a second pause signal is sent to the first controller 4. The first controller 4 is also used to pause the forward movement of the disk pusher box 3 after receiving the second pause signal.

[0092] The second limit position is the limit position that the disc pushing box 3 can reach during its advancement. If the disc pushing box 3 reaches the second limit position, it indicates that an abnormality has occurred during its advancement. The first controller 4 pauses the advancement of the disc pushing box 3 and enters the abnormality handling stage.

[0093] The fourth detection unit 9 may be a pair of an infrared receiver and an infrared transmitter. The infrared receiver is disposed on the movable platform of the disc ejector 3. The infrared receiver is located at the second extreme position of the disc ejector 3 during its forward movement. The infrared transmitter is disposed on the disc ejector 3. When the disc ejector 3 moves to the second extreme position, the infrared light emitted by the infrared transmitter is received by the infrared receiver. At this time, the infrared receiver transmits a second pause signal to the first controller 4. When the first controller 4 receives the second pause signal, it indicates that the disc ejector 3 is at the second extreme position, indicating that an abnormality has occurred during the forward movement of the disc ejector 3. The first controller 4 then pauses the forward movement of the disc ejector 3 and enters the abnormality handling phase.

[0094] Example 6

[0095] like Figure 11 A battery box locking control method is shown, which can use the above-mentioned battery box locking control system. The battery box locking control method includes the following steps:

[0096] Step 100: The suction cup 32 of the tray pushing box 3 is attached to the battery box 1 and remains connected. The battery box 1 is located in front of the tray pushing box 3. The tray pushing box 3 is controlled to move forward until the battery box 1 is located in the battery compartment 2.

[0097] Step 200: When the battery box 1 is located in the battery compartment 2, the tray pusher 3 is controlled to continue to move forward so that the suction cup 32 is retracted into the tray pusher box 31;

[0098] Step 300: The first detection unit 6 detects whether the suction cup 32 is retracted to the first predetermined position. If so, step 400 is executed; if not, step 200 is executed.

[0099] Step 400: Control the disc pushing box 3 to stop moving forward, control the disc pushing box 3 to separate from the battery box 1, and control the disc pushing box 3 to return to a designated position.

[0100] After the battery box 1 is installed in the battery compartment 2, the tray pushing box 3 can continue to move forward and slowly stop, so that the tray pushing box 3 has a buffer process before stopping, ensuring that the tray pushing box 3 can stop smoothly and ensure that the battery box 1 is installed in place in the battery compartment 2.

[0101] Example 7

[0102] like Figure 12 As shown, the battery box locking control method of this embodiment is a further improvement of Example 6.

[0103] Step 100 of the battery box locking control method includes the following steps:

[0104] Step 101: The suction cup 32 of the tray pushing box 3 is attached to the battery box 1 and remains connected. The battery box 1 is located in front of the tray pushing box 3. The first controller 4 controls the tray pushing box 3 to move forward.

[0105] Step 102: When the first controller 4 drives the disk ejector 3 to advance to the second predetermined position, the first controller 4 sends a second signal to the third controller 34. The third controller 34 controls the push rod 33 to press the button 13 upon receiving the second signal, thereby activating and resetting the lock tongue 12.

[0106] Step 103: The fourth detection unit 9 detects whether the disc ejector 3 reaches the second limit position during its forward movement. If so, step 104 is executed; otherwise, step 105 is executed.

[0107] Step 104: the fourth detection unit 9 sends a second pause signal to the first controller 4. The first controller 4 pauses the advancement of the disc ejector 3 after receiving the second pause signal.

[0108] Step 105 : The first controller 4 controls the tray pushing box 3 to continue moving forward until the battery box 1 is located in the battery compartment 2 .

[0109] Through the above method, the push tray box 3 can push the battery box 1 until the battery box 1 is successfully installed in the battery compartment 2.

[0110] Example 8

[0111] like Figure 13 As shown, the battery box locking control method of this embodiment is a further improvement of Example 6.

[0112] Step 400 of the battery box locking control method includes the following steps:

[0113] Step 401: The first detection unit 6 sends a first signal to the first controller 4. After receiving the first signal, the first controller 4 stops driving the disc ejector 3 forward.

[0114] Step 402: The first detection unit 6 sends a first signal to the second controller 5. After receiving the first signal, the second controller 5 controls the ejector box 3 to separate from the battery box 1.

[0115] Step 403: The third detection unit 8 detects whether the lock tongue 12 and the lock seat 21 are in a locked state. If not, step 404 is executed; if yes, step 405 is executed.

[0116] Step 404: Enter the exception handling program and the process ends;

[0117] Step 405: The third detection unit 8 sends a permission signal to the first controller 4, and the first controller 4 controls the disk ejector 3 to return;

[0118] Step 406: The second detection unit 7 detects whether the disk ejector 3 reaches the first limit position during its return process. If so, step 407 is executed; otherwise, step 408 is executed.

[0119] Step 407: The second detection unit 7 sends a first pause signal to the first controller 4. After receiving the first pause signal, the first controller 4 pauses the return of the disc ejector 3. At this time, it is proved that the operation of the disc ejector 3 is abnormal, and the abnormality handling program is entered.

[0120] Step 408: The first controller 4 controls the disk pushing box 3 to return until the disk pushing box 3 reaches the designated position.

[0121] By using the above method, the disc ejector box 3 can be smoothly returned to the designated position.
