[0062] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0063] like Figures 1 to 4As shown, the present invention provides an unlocking device, which is used to match the locking mechanism on the electric vehicle to unlock the battery pack. The unlocking device includes an unlocking rod 1, a driving mechanism 2 and a controller. The unlocking rod 1 includes a rod head 11 matched with the unlocking point 101 of the locking mechanism. The driving mechanism 2 is connected to the unlocking rod 1. The driving mechanism 2 is used to drive the unlocking rod 1 to move to the locking position and the unlocking position; when the unlocking rod 1 is in the unlocking position, the unlocking rod 1 is aligned with the unlocking point 101 of the locking mechanism; when the unlocking rod 1 is in the locking position, the unlocking rod 1 does not hinder the action of the locking mechanism; the controller is used to control the action of the driving mechanism 2 to move the unlocking rod 1 to the locking position and the unlocking position.

[0064] The unlocking device described above can be applied to the locked state or unlocked state of the battery pack by setting the locked position and the unlocked position of the unlocking lever 1 and controlling the unlocking lever 1 to move between the locked position and the unlocked position.

[0065] like Figures 1 to 3 As shown, the driving mechanism 2 includes a guide rail 21, a slider 22, a transmission component 23 and a driving component 24. The guide rail 21 is fixed on the base plate 7; the slider 22 slides on the guide rail 21, and the unlocking rod 1 is fixed on the slider 22. When the slider 22 slides on the guide rail 21, the unlocking rod 1 passes through a locking position and an unlocking position; the transmission direction of the transmission component 23 is parallel to the extension direction of the guide rail 21, and the transmission component 23 is connected to the slider 22; the driving component 24 is connected to the transmission component 23, and the driving component 24 is connected to the controller signal, and the driving component 24 drives the slider 22 to slide on the guide rail 21 through the transmission component 23.

[0066] The slider 22 slides on the guide rail 21, driving the unlocking rod 1 to move in the direction of the guide rail 21. During the sliding of the slider 22 on the guide rail 21, the unlocking rod 1 passes through the locking position and the unlocking position; so that when the battery pack is unlocked, the unlocking rod 1 is located in the unlocking position, and the unlocking rod 1 is aligned with the unlocking point 101 of the locking mechanism; and when the battery pack is locked, the unlocking rod 1 is located in the locking position, and the unlocking rod 1 does not hinder the action of the locking mechanism.

[0067] The driving mechanism 2 further includes a connecting assembly 25, and the transmission assembly 23 is connected to the slider 22 via the connecting assembly 25. A specific structure of the connecting assembly 25 is as follows: the connecting assembly 25 includes a baffle 251 and a paddle 252, the baffle 251 is fixedly connected to the transmission assembly 23; the paddle 252 is fixedly connected to the unlocking rod 1, and the paddle 252 has a limiting end 254 extending toward the baffle 251, and the limiting end 254 can abut against the edge of the paddle 252.

[0068] In order to ensure that the limiting end 254 can always abut against the edge of the paddle 252 without being subjected to external force, the connecting assembly 25 further includes a first restoring member 253, one end of which is connected to the paddle 252, and the other end of which is a fixed end, the fixed end of which is fixed to the first support frame 8, the first support frame 8 is fixed to the bottom plate 7, and the first restoring member 253 maintains a pulling force on the paddle 252; the fixed end of the first restoring member 253 and the limiting end 254 of the paddle 252 are respectively located on both sides of the baffle 251 along the conveying direction of the conveying assembly 23. The first restoring member 253 always applies a pulling force to the paddle 252 to make the limiting end 254 abut against the baffle 251, and under the action of an external force in the opposite direction greater than the pulling force of the first restoring member 253, the limiting end 254 can be away from the baffle 251.

[0069] The unlocking device further includes a buffer component, which is connected to the unlocking rod 1 and applies a pulling force to the unlocking rod 1. When the connecting component 25 is a structure of a baffle 251 and a paddle 252, the buffer component is a second reset member 255. One end of the second reset member 255 is connected to the paddle 252, and the other end of the second reset member 255 is a fixed end. The fixed end of the second reset member 255 is fixed to the second support frame 9, and the second support frame 9 is fixed on the bottom plate 7. The second reset member 255 maintains a pulling force on the paddle 252; the fixed end of the second reset member 255 and the limiting end 254 of the paddle 252 are located on the same side of the baffle 251 along the conveying direction of the conveying assembly 23. When the limiting end 254 of the paddle 252 is away from the baffle 251 and the external force disappears instantly, the second reset member 255 will slow down the speed of the paddle 252 returning to avoid damage to the baffle 251 and the conveying assembly 23 due to excessive reaction force of the paddle 252.

[0070] A specific connection structure between the baffle 251 and the paddle 252 is as follows: Figure 2 As shown, the edge of the baffle 251 facing the paddle 252 forms a groove 256 for accommodating the limit end 254, and the limit end 254 can be abutted against the groove 256. Figure 2 In addition to the connection structure between the baffle 251 and the paddle 252 shown, the baffle 251 and the paddle 252 can also be connected in other ways, such as the baffle 251 and the limiting end 254 of the paddle 252 are snap-fitted; or, a protrusion is formed on the edge of the baffle 251 facing the paddle 252, and a concave limiting groove is formed on the edge of the baffle 251 facing the limiting end 254, and the protrusion can rest in the limiting groove.

[0071] The unlocking device further includes a first sensor 3, which is used to detect whether the unlocking rod 1 reaches the locked position. The first sensor 3 is also used to send a first in-position signal when the unlocking rod 1 reaches the locked position. The controller is also used to control the driving mechanism 2 to stop the movement of the unlocking rod 1 when receiving the first in-position signal. Figures 1 to 3 As shown, the first sensor 3 is arranged on one side of the transmission component 23; when the unlocking rod 1 reaches the locking position, the first sensor 3 can detect the connecting component 25; the first sensor 3 is also used to send a first in-position information when the connecting component 25 is detected, and the controller is also used to control the driving component 24 to stop rotating when receiving the first in-position signal.

[0072] The unlocking device also includes a second sensor 4, which is used to detect whether the position of the unlocking rod 1 reaches the unlocking position. The second sensor 4 is also used to send a second in-position signal when the unlocking rod 1 reaches the unlocking position. The controller is also used to control the driving mechanism 2 to stop the movement of the unlocking rod 1 when receiving the second in-position signal.

[0073] When the driving mechanism 2 is Figures 1 to 3 As shown, the second sensor 4 is arranged on one side of the transmission component 23; when the unlocking rod 1 reaches the unlocking position, the second sensor 4 can detect the connecting component 25; the second sensor 4 is also used to send a second in-position information when the connecting component 25 is detected, and the controller is also used to control the driving component 24 to stop rotating when receiving the second in-position signal.

[0074] The first sensor 3 and the second sensor 4 are arranged on a fixing frame 5, and an adjustment slot 51 is arranged on the fixing frame 5. The fixing frame 5 is mounted on the bottom plate 7 by a fixing bolt 6 passing through the adjustment slot 51, and the position of the fixing frame 5 on the bottom plate 7 can be adjusted by adjusting the position of the fixing bolt 6 in the adjustment slot 51.

[0075] like Figures 1 to 3 As shown, a specific structure of the transmission component 23 is as follows: the transmission component 23 includes a transmission belt 231, a driving wheel 232, and a driven wheel 233. The transmission belt 231 is connected to the slider 22. The driving wheel 232 and the driven wheel 233 are located at both ends of the transmission belt 231. The driving wheel 232 and the driven wheel 233 tighten the transmission belt 231. The extension direction of the transmission belt 231 is the transmission direction of the transmission component 23. The driving component 24 drives the driving wheel 232 to rotate around the axis. The driving component 24 includes a driving motor 241 and a transmission box 242. The rotating shaft of the driving motor 241 is axially connected to the input shaft of the transmission box 242, and the output shaft of the transmission box 242 is axially connected to the rotating shaft of the driving wheel 232.

[0076] In order to ensure the tension of the conveyor belt 231, the conveyor assembly 23 also includes a moving seat 234, a base 235 and an elastic connector 236. The rotating shaft of the driven wheel 233 is fixed on the moving seat 234, the base 235 is fixed on the bottom plate 7, the moving seat 234 is connected to the base 235 through the elastic connector 236, and the elastic connector 236 applies a pulling force to the moving seat 234 to keep the driven wheel 233 away from the driving wheel 232. Since the elastic connector 236 applies a pulling force to the moving seat 234, the driven wheel 233 always keeps away from the driving wheel 232. When the conveyor belt 231 is stretched due to aging, the elastic connector 236 automatically adjusts the position of the driven wheel 233 to keep the conveyor belt 231 in a tensioned state.

[0077] A specific structure of the elastic connecting member 236 is as follows: a slide groove 237 is formed in the moving seat 234, the extension direction of the slide groove 237 is parallel to the transmission direction of the conveyor belt 231, and the driven wheel 233 is installed at one end of the slide groove 237; the elastic connecting member 236 includes a connecting bolt 238, a limit block 239 and a compression spring 2310, the connecting bolt 238 passes through the base 235 and the moving seat 234, the threaded end of the connecting bolt 238 is located in the slide groove 237 of the moving seat 234, and the axis of the connecting bolt 238 is parallel to the transmission direction of the conveyor belt 231; the limit block 239 is installed at the threaded end of the connecting bolt 238, the limit block 239 cooperates with the inner circumference of the slide groove 237, and the limit block 239 can slide in the slide groove 237; the compression spring 2310 is sleeved on the connecting bolt 238, and the two ends of the compression spring 2310 are respectively against the limit block 239 and the end of the slide groove 237 away from the driven wheel 233. When the conveyor belt 231 is stretched due to aging, the compression spring 2310 applies a thrust to the movable seat 234 to move the movable seat 234 away from the driving wheel 232 , so that the conveyor belt 231 is always kept in a tensioned state.

[0078] like Figure 4 As shown, the unlocking rod 1 also includes a supporting tube 12 and a reset spring 13. The supporting tube 12 is connected to the driving mechanism 2. The reset spring 13 is placed in the supporting tube 12. The two ends of the rod head 11 are respectively a mating end 111 and a mounting end 112. The mating end 111 of the rod head 11 is used to match the unlocking point 101 of the locking mechanism. The mounting end 112 of the rod head 11 is installed in the supporting tube 12, and the mounting end 112 of the rod head 11 abuts against the end of the reset spring 13.

[0079] When the unlocking rod 1 abuts against the unlocking point 101 of the locking mechanism, the rod head 11 of the unlocking rod 1 first partially retracts into the support tube 12. When the unlocking rod 1 continues to push up, the reset spring 13 is compressed to the limit state, and then the rod head 11 of the unlocking rod 1 can push up the unlocking point 101 of the locking mechanism to activate the locking mechanism. By providing the reset spring 13, the rod head 11 of the unlocking rod 1 has a certain degree of buffering when it contacts the unlocking point 101 of the locking mechanism.

[0080] The battery pack of an electric vehicle is fixed in a fixed seat, and a shuttle vehicle can be used to install and remove the battery pack. During the installation of the battery pack, the battery pack needs to be locked in the fixed seat, and during the removal of the battery pack, the battery pack needs to be unlocked from the fixed seat. The above unlocking device is applied to the shuttle vehicle to achieve locking and unlocking of the battery pack.

[0081] A lock structure for locking a battery pack in a fixed seat of an electric vehicle Figure 5 As shown. The lock structure is arranged on the inner circumference of the fixing seat, and the lock structure includes a lock base 103 and a lock link 102. The lock base 103 is provided with a lock slot 104 and a lock tongue 105 arranged in the lock slot 104, and the lock link 102 can drive the lock tongue 105 to rotate. A lock shaft is arranged on the circumference of the battery pack. When the battery pack is installed in the fixing seat, the lock shaft of the battery pack is fixed in the lock base 103; specifically, the lock shaft is inserted into the lock slot 104 from the entrance of the lock slot 104 until the locking position, and the lock tongue 105 is lowered to lock the lock shaft in the lock slot 104. When the battery pack needs to be removed from the fixing seat, the lock shaft of the battery pack needs to be removed from the lock slot 104 of the lock base 103; specifically, the lock link 102 is actuated to drive the lock tongue 105 to rotate, so that the lock tongue 105 is retracted, and the lock shaft of the battery pack can be removed from the lock slot 104. The lock link 102 is provided with an unlocking point 101. During the disassembly of the battery pack, the unlocking rod 1 of the unlocking device presses against the unlocking point 101 of the lock link 102 to retract the lock tongue 105.

[0082] The method for unlocking a battery pack using a shuttle vehicle having the unlocking device comprises the following steps:

[0083] S1. Move the shuttle so that the battery tray of the shuttle is directly under the battery pack;

[0084] S2, move the unlocking rod 1 to the unlocking position, so that the rod head 11 of the unlocking rod 1 is aligned with the unlocking point 101 of the lock link 102;

[0085] S3, the battery tray and the unlocking device are raised, the rod head 11 of the unlocking rod 1 presses against the unlocking point 101 of the lock link 102, and the battery tray lifts the battery pack; at this time, the rod head 11 of the unlocking rod 1 is compressed, and the lock link 102 remains in the locked position;

[0086] S4, the battery tray and the unlocking device continue to rise, and the rod head 11 of the unlocking rod 1 lifts the lock connecting rod 102, so that the lock base 103 is in the unlocking state;

[0087] S5. Move the battery tray and the unlocking device horizontally, so that the battery tray drives the battery pack to move horizontally together, and the lock shaft of the battery pack moves toward the exit of the lock slot 104; at this time, the rod head 11 of the unlocking rod 1 always presses against the unlocking point 101 of the lock link 102, and drives the lock link 102 to move, so that the lock tongue 105 retracts, and the lock shaft of the battery pack can reach the exit of the lock slot 104; in this process, since the action of the unlocking rod 1 lags behind the action of other components of the unlocking device, the first reset member 253 will be stretched;

[0088] S6. When the lock shaft of the battery pack reaches the exit of the lock slot 104, the electric vehicle is raised as a whole to allow the battery pack to fall into the battery tray, and the rod head 11 of the unlocking rod 1 is separated from the unlocking point 101 of the lock link 102; at this time, the unlocking rod 1 is reset, and the second reset member 255 will pull the unlocking rod 1 to delay the reset of the unlocking rod 1. The instantaneous reaction force of the unlocking rod 1 separating from the lock link 102 is alleviated by the second reset member 255, thereby avoiding the instantaneous reaction force of the unlocking rod 1 and damaging other components of the unlocking device, such as the conveyor belt 231, etc.

[0089] When the shuttle with the unlocking device is used to lock the battery pack, the unlocking rod 1 of the unlocking device moves to the locking position, avoiding the position of the lock link 102, so that the unlocking rod 1 will not hinder the movement of the lock link 102 during the entire locking process.
