[0041] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] like Figures 1-6 As shown, according to the battery quick-disassembly system 100 for a vehicle described in an embodiment of the present invention, the battery quick-disassembly system 100 is arranged on the vehicle, and the battery quick-disassembly system 100 is used to fix the battery pack 200 on the vehicle, and when the battery quick-disassembly system 100 unlocks the battery pack 200, the battery pack 200 can be removed from the vehicle and replaced, so as to achieve the technical effect of quickly replacing the battery pack 200 on the vehicle.

[0044] The battery quick-release system 100 according to an embodiment of the present invention includes a hydraulic locking mechanism 10, a drive mechanism 40, and a plurality of pipelines 50. The hydraulic locking mechanism 10 includes a drive unit 20 and a clamping structure 30. The clamping structure 30 is movably mounted on the drive unit 20 and has a locked position and an unlocked position. In the locked position, the clamping structure 30 is adapted to lock the battery pack 200 to the vehicle, and in the unlocked position, the clamping structure 30 unlocks the battery pack 200. The drive unit 20 can drive the clamping structure 30 from the locked position to the unlocked position, or vice versa. The battery pack 200 is used to power the vehicle to enable the vehicle to travel on the road.

[0045] When the battery pack 200 is installed in place on the vehicle, the driving unit 20 drives the clamping structure 30 to move from the unlocked position to the locked position. The clamping structure 30 can lock the battery pack 200 to the vehicle, which can prevent the battery pack 200 from falling off the vehicle during driving, thereby ensuring normal use of the vehicle. When the battery pack 200 is exhausted or the battery pack 200 is damaged, the driving unit 20 drives the clamping structure 30 to move from the locked position to the unlocked position. The clamping structure 30 can unlock the battery pack 200 from the vehicle, and the battery pack 200 can be quickly removed from the vehicle, which helps the vehicle to quickly replace a fully charged or normal battery pack 200. Therefore, by using the hydraulic locking mechanism 10 to selectively lock the battery pack 200, the vehicle can quickly install or remove the battery pack 200, thereby improving the efficiency of replacing the battery pack 200 in the vehicle.

[0046] Furthermore, there may be multiple hydraulic locking mechanisms 10, at least one hydraulic locking mechanism 10 and the other hydraulic locking mechanisms 10 are arranged on different sides of the vehicle, and the multiple hydraulic locking mechanisms 10 are respectively suitable for locking different sides of the battery pack 200 to ensure that the battery pack 200 is reliably fixed to the vehicle. Figure 1 In the embodiment shown, there may be twelve hydraulic locking mechanisms 10, of which six hydraulic locking mechanisms 10 may be arranged on the first side of the vehicle, i.e. Figure 1 The six hydraulic locking mechanisms 10 provided on the first side of the vehicle are all suitable for locking the battery pack 200 to the first side of the vehicle, and the other six hydraulic locking mechanisms 10 can be provided on the second side of the vehicle, i.e. Figure 1 On the right side of the figure, the six hydraulic locking mechanisms 10 provided on the second side of the vehicle are suitable for locking and fixing the battery pack 200 to the second side of the vehicle, thereby preventing the battery pack 200 from falling off from the first side or the second side of the vehicle, thereby ensuring the normal use of the vehicle.

[0047] In addition, the driving mechanism 40 has a storage unit, which stores a pressure medium. In some specific embodiments, the storage unit can be an oil can or an oil tank, and the pressure medium can be a liquid medium such as hydraulic oil or a gaseous medium. Multiple pipelines 50 are connected between the storage unit and the driving part 20, and each pipeline 50 is selectively opened to allow the pressure medium to flow into or out of the driving part 20, so that the driving part 20 drives the clamping structure 30 to move to a locked position or an unlocked position.

[0048] When the pipeline 50 is open and pressure medium flows into the driver unit 20, the pressure of the pressure medium can drive the driver unit 20 to drive the clamping structure 30 to move, and the clamping structure 30 can move from the unlocked position to the locked position to lock the battery pack 200. When the pipeline 50 is blocked to restrict the flow of pressure medium into or out of the driver unit 20, a certain amount of pressure medium remains in the driver unit 20. Under the pressure of the pressure medium, the pressure medium can maintain the driving force of the driver unit 20, so that the driver unit 20 can drive the clamping structure 30 to remain in the locked position to lock the battery pack 200. When the pipeline 50 is open and the pressure medium flows out of the driver unit 20, the driver unit 20 can drive the clamping structure 30 to move, and the clamping structure 30 can move from the locked position to the unlocked position to unlock the battery pack 200. At this time, the assembler or robotic arm can remove the battery pack 200 from the vehicle.

[0049] In addition, when the vehicle is collided during driving and the battery pack 200 catches fire, multiple pipes 50 can be opened and the pressure medium can flow out of the drive unit 20. The battery quick release system 100 can actively unlock the battery pack 200 so that the battery pack 200 can be separated from the vehicle under the action of gravity. The flame generated when the battery pack 200 burns has less impact on the vehicle, thereby reducing the scope of the vehicle's fire, which is beneficial to reducing the user's property loss and protecting the user's personal safety, thereby further improving the vehicle's user experience.

[0050] It should be noted that when there are multiple hydraulic locking mechanisms 10, each pipeline 50 can be connected to the drive units 20 of one or more hydraulic locking mechanisms 10. That is, each pipeline 50 is suitable for simultaneously directing the pressure medium into or out of multiple drive units 20, thereby driving the multiple drive units 20 to drive the clamping structure 30 to move to the locked position or unlocked position. If one or more of the pipelines 50 are damaged, the pressure medium in the damaged pipeline 50 will leak, resulting in a loss of pressure in the damaged pipeline 50, and the clamping structure 30 will move from the locked position to the unlocked position. Since the remaining pipeline 50 is intact and pressure medium remains in the remaining pipeline 50, the battery quick-disassembly system 100 can control the clamping structure 30 to remain in the locked position through the pipeline 50 in good condition so that the clamping structure 30 continues to lock the battery pack 200 on the vehicle, thereby ensuring the normal driving of the vehicle. At the same time, the battery quick-disassembly system 100 can send a signal to the vehicle's controller (such as the vehicle controller, etc.) to enable the vehicle's controller to control the vehicle's alarm device to send an alarm prompt to the people in the vehicle. The user can repair the pipeline 50 in time. Before the pipeline 50 is repaired, the vehicle can be used normally, thereby effectively improving the working reliability of the vehicle.

[0051] Preferably, each pipeline 50 can be communicated with the driving portion 20 of at least one hydraulic locking mechanism 10 provided on the first side of the vehicle and the driving portion 20 of at least one hydraulic locking mechanism 10 provided on the second side of the vehicle. Figure 1 In the illustrated embodiment, when there are two pipelines 50, the two pipelines 50 can be respectively connected to the driving parts 20 of the three hydraulic locking mechanisms 10 provided on the first side of the vehicle and the driving parts 20 of the three hydraulic locking mechanisms 10 provided on the second side of the vehicle, and the multiple hydraulic locking mechanisms 10 connected to one of the pipelines 50 and the multiple hydraulic locking mechanisms 10 connected to the other pipeline 50 are arranged angularly symmetrically on both sides of the vehicle. In this way, when one of the pipelines 50 is damaged and the hydraulic locking mechanism 10 corresponding to the damaged pipeline 50 fails, the locking force generated by the hydraulic locking mechanism 10 corresponding to the other pipeline 50 in good condition can lock and fix the battery pack 200 to the first side and the second side of the vehicle, and the battery pack 200 is difficult to fall off from the first side or the second side of the vehicle, thereby further improving the working reliability of the vehicle.

[0052] Therefore, by setting multiple pipelines 50 between the storage unit and the drive unit 20, when some pipelines 50 are damaged and the pressure medium leaks, the remaining pipelines 50 can work normally to avoid failure of the hydraulic locking mechanism 10. Compared with the existing technology, the battery quick release system 100 can reliably fix the battery pack 200, thereby preventing the battery pack 200 from falling from the vehicle, and thus improving the working reliability of the vehicle.

[0053] It should be noted that when multiple pipelines 50 of the battery quick release system 100 are damaged and the pipelines 50 lose pressure, the battery quick release system 100 can quickly fill the pipelines 50 with pressure medium. At this time, the speed at which the battery quick release system 100 injects pressure medium into the pipelines 50 is not less than the leakage rate of the pressure medium in the pipelines 50. In this way, the driving force of the driving unit 20 can be maintained, thereby preventing the battery pack 200 from falling off the vehicle immediately. The battery pack 200 will fall off the vehicle after the pressure medium is completely exhausted, that is, the time required for the battery pack 200 to fall off the vehicle is extended, which increases the user's reaction time to deal with abnormalities in the battery quick release system 100.

[0054] In some embodiments of the present invention, Figure 1As shown, the battery quick-disassembly system 100 may further include a control unit 60. Each pipeline 50 may be provided with an electromagnetic manual integrated valve 70. The electromagnetic manual integrated valve 70 in each pipeline 50 is in communication with the control unit 60. The control unit 60 is configured to control the opening or closing of the corresponding electromagnetic manual integrated valve 70. The control unit 60 may be configured as a controller, etc. The control unit 60 may independently control the opening or closing of each electromagnetic manual integrated valve 70 to control the conduction or blocking of the corresponding pipeline 50.

[0055] In addition, the electromagnetic manual integrated valve 70 and the control unit 60 can be communicated with each other by means of a wired communication connection, thereby ensuring the reliability of the communication connection between the electromagnetic manual integrated valve 70 and the control unit 60. Of course, in some other embodiments, the electromagnetic manual integrated valve 70 and the control unit 60 can be communicated with each other by means of a wireless communication connection. The wireless communication connection can reduce the wiring harness between the electromagnetic manual integrated valve 70 and the control unit 60, which is beneficial to the arrangement of the battery quick release system 100 on the vehicle, and at the same time can make the arrangement positions of the electromagnetic manual integrated valve 70 and the control unit 60 on the vehicle more flexible.

[0056] At the same time, the electromagnetic manual integrated valve 70 is located between the storage unit and the drive unit 20. When the control unit 60 controls the electromagnetic manual integrated valve 70 to open, the electromagnetic manual integrated valve 70 can connect the corresponding pipeline 50, the pipeline 50 can be connected to the storage unit, and the drive unit 20 can be connected to the storage unit through the pipeline 50. The pressure medium in the storage unit can flow into the drive unit 20 through the pipeline 50, or the pressure medium in the drive unit 20 can flow out to the storage unit through the pipeline 50. The pressure in the pipeline 50 changes, and the drive unit 20 can drive the clamping structure 30 to move to the locked position or unlocked position according to the pressure change of the pressure medium in the drive unit 20, so that the clamping structure 30 can lock or unlock the battery pack 200. After the battery pack 200 is installed on the vehicle, the control unit 60 can simultaneously open multiple electromagnetic manual integrated valves 70 to open multiple pipelines 50. Pressure medium can flow through the multiple pipelines 50 into the drive unit 20 to drive the clamping structure 30 to the locked position. In other words, the multiple hydraulic locking mechanisms 10 can jointly lock the battery pack 200. This can improve the connection strength between the battery pack 200 and the vehicle, prevent the battery pack 200 from falling from the vehicle, and improve the operating reliability of the vehicle. Furthermore, when the battery pack 200 needs to be removed from the vehicle, the control unit 60 can simultaneously open multiple electromagnetic manual integrated valves 70 to open multiple pipelines 50. Pressure medium can flow out of the drive unit 20 through the multiple pipelines 50 to drive the clamping structure 30 to the unlocked position. In other words, the multiple hydraulic locking mechanisms 10 can jointly unlock the battery pack 200, freeing the battery pack 200 from the locking force and preventing the battery pack 200 from being hindered when removed from the vehicle.

[0057] When the control unit 60 controls the electromagnetic manual integrated valve 70 to close, the electromagnetic manual integrated valve 70 can block the corresponding pipeline 50, the pipeline 50 is not connected to the storage unit, and the drive unit 20 is not connected to the storage unit, and the storage unit and the drive unit 20 cannot exchange pressure medium through the pipeline 50. When the clamping structure 30 is in the locked position, the electromagnetic manual integrated valve 70 is closed, and pressure medium remains in the pipeline 50 and the drive unit 20, the remaining pressure medium can enable the drive unit 20 to drive the clamping structure 30 to remain in the locked position, so that the drive mechanism 40 does not need to inject pressure medium into the pipeline 50 for a long time, thereby reducing the energy consumed by the battery quick disassembly system 100. Therefore, by setting an electromagnetic manual integrated valve 70 and a control unit 60 in the battery quick disassembly system 100, the technical effect of selectively connecting multiple pipelines 50 is achieved. The control unit 60 can automatically unlock or lock the battery pack 200 by controlling the opening and closing of the electromagnetic manual integrated valve 70. The assembler does not need to manually assemble the battery pack 200 to the vehicle, which can reduce the vehicle's assembly time and battery replacement time, thereby improving the vehicle's assembly efficiency and battery replacement efficiency.

[0058] Of course, when the battery pack 200 catches fire, the control unit 60 can also automatically open the electromagnetic manual integrated valve 70 to release the battery pack 200 from the vehicle, thereby improving the driving safety of the vehicle and reducing the degree of damage to the vehicle, thereby improving the user experience of the vehicle. Furthermore, the control unit 60 can be connected to the vehicle's controller, for example, the control unit 60 can be connected to the vehicle's vehicle controller, and the vehicle's controller can be connected to the vehicle's instrument panel, center control panel, etc. The user can control the control unit 60 through the instrument panel, center control panel, etc. to control the electromagnetic manual integrated valve 70 to open and close, which helps assemblers replace the battery pack 200 on the vehicle through the battery quick disassembly system 100, thereby improving the vehicle's battery replacement efficiency.

[0059] In some embodiments of the present invention, the electromagnetic manual integrated valve 70 can be set in the passenger compartment of the vehicle. Specifically, by setting the electromagnetic manual integrated valve 70 in the passenger compartment of the vehicle, the personnel in the passenger compartment can manually operate the electromagnetic manual integrated valve 70 to open. When the vehicle is completely powered off and / or the battery pack 200 is on fire and / or the control unit 60 fails, the control unit 60 cannot control the electromagnetic manual integrated valve 70 to open. By manually opening the electromagnetic manual integrated valve 70, the electromagnetic manual integrated valve 70 can conduct the pipeline 50. The pressure medium in the pipeline 50 and the drive unit 20 can flow out to the storage unit through the electromagnetic manual integrated valve 70. The pressure in the pipeline 50 is reduced, and the drive unit 20 can be opened. By driving the latching structure 30 to move from the locked position to the unlocked position, the battery pack 200 can be unlocked and the battery pack 200 can fall from the vehicle on its own, so that the assembler or rescuer can remove the battery pack 200 from under the vehicle, so that the assembler can manually replace the battery pack 200, or prevent the burning battery pack 200 from igniting other areas of the vehicle, reducing the burning area of ​​the vehicle, avoiding the battery pack 200 from causing harm to the occupants in the vehicle, and facilitating the rescue of the occupants in the vehicle, thereby improving the safety of the vehicle and helping to improve the vehicle's user experience.

[0060] Furthermore, the electromagnetic manual integrated valve 70 may include: a valve body 701, a manual safety pin 702, and an electromagnetic controller. The electromagnetic controller is disposed in the valve body 701 and is in communication with the control unit 60. The valve body 701 is provided with a valve having a first connection port and a second connection port. One of the first connection port and the second connection port can be connected to the storage unit, and the other of the first connection port and the second connection port can be connected to the drive unit 20. When the first connection port and the second connection port are connected, pressure medium can flow between the storage unit and the drive unit 20. The valve is movably disposed in the valve body 701 and has a communication hole connecting the first connection port and the second connection port. When the communication hole moves to connect with both the first connection port and the second connection port, pressure medium can flow between the first connection port and the second connection port. When the valve moves to disconnect from at least one of the first connection port and the second connection port, pressure medium cannot flow between the first connection port and the second connection port.

[0061] In addition, the control unit 60 is used to control the electromagnetic controller to control the valve to open or close, so as to connect or isolate the first connection port and the second connection port. Specifically, the electromagnetic controller can drive the valve to move in the valve body 701. The electromagnetic controller can adjust the movement direction and movement distance of the valve to adjust the opening and closing conditions and the opening degree between the first connection port and the second connection port, and the control unit 60 can control the electromagnetic controller to drive the valve to move so that the valve opens or closes the electromagnetic manual integrated valve 70 according to the requirements of the control unit 60.

[0062] A manual safety pin 702 is provided on the valve body 701 and connected to the valve, and the valve is opened or closed by the manual safety pin 702. The manual safety pin 702 is detachably mounted on the valve to manually open or close the valve. The provision of the manual safety pin 702 enables manual disassembly and assembly of the battery. For example, when the vehicle is completely powered off and the battery catches fire, a person in the passenger compartment can remove the manual safety pin 702 mounted on the valve, manually open the valve, and allow the medium in the locking mechanism to flow back to the storage unit, thereby enabling the battery to be disassembled, allowing the battery in danger to be separated from the vehicle, and protecting the people in the cockpit from damage by the battery.

[0063] In some embodiments of the present invention, Figure 1 As shown, each pipeline 50 includes a first pipeline section 501 and a second pipeline section 502. The first pipeline section 501 is connected between the first connection port and the storage unit, and the second pipeline section 502 is connected between the second connection port and the drive unit 20. When the pipeline 50 is open, the pipeline 50 can guide the pressure medium. Pressure medium flows through both the first pipeline section 501 and the second pipeline section 502. The first pipeline section 501 and the second pipeline section 502 can jointly guide the pressure medium from the storage unit to the drive unit 20. After the pressure medium flows into the drive unit 20, it can drive the locking structure 30 to lock the battery pack 200. Alternatively, the first pipeline section 501 and the second pipeline section 502 can jointly guide the pressure medium from the drive unit 20 to the storage unit. After the pressure medium flows out of the drive unit 20, it can drive the locking structure 30 to unlock the battery pack 200. When the clamping structure 30 locks the battery pack 200 and pressure medium remains in the first pipeline section 501 and the second pipeline section 502, the valve is closed by controlling the electromagnetic controller, and the valve cannot connect the first connection port and the second connection port. The pressure medium will be blocked in the second pipeline section 502. The second pipeline section 502 can maintain the pressure of the pressure medium, so that the driving force of the pressure medium acting on the drive unit 20 can be stable. The drive unit 20 can drive the clamping structure 30 to reliably lock the battery pack 200, thereby achieving the technical effect of the hydraulic locking mechanism 10 locking the battery pack 200 for a long time, and can improve the working stability of the battery quick disassembly system 100.

[0064] In some embodiments of the present invention, Figure 1As shown, the drive mechanism 40 further includes a drive pump 401. Multiple pipelines 50 are connected to the drive pump 401, and the drive pump 401 is also connected to the storage unit. The drive pump 401 is in communication with a control unit 60, which is used to control the operation of the drive pump 401. The drive pump 401 can generate negative pressure. When the pipelines 50 are open, the control unit 60 controls the drive pump 401 to operate. The drive pump 401 can draw the pressure medium in the storage unit into the pipelines 50. The drive pump 401 can pressurize the pressure medium and direct it to the drive unit 20. The pressure generated by the pressure medium can cause the drive unit 20 to drive the locking structure 30 to lock the battery pack 200.

[0065] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the driving part 20 includes: a fixing part 201, a connecting part 202 and a transmission rod 203. The fixing part 201 and the connecting part 202 are connected. The fixing part 201 is suitable for installation on a vehicle. In some specific examples of the present invention, the body assembly of the vehicle may include a battery mounting bracket 300, and the fixing part 201 is installed at the lower end of the battery mounting bracket 300. In other embodiments of the present application, the body assembly includes a crossbeam, a longitudinal beam or a door sill beam, etc., and the fixing part 201 can be installed at the lower end of the crossbeam, the longitudinal beam or the door sill beam. Optionally, the fixing part 201 can be installed by bolt connection, clamping, etc., and no specific limitation is made here.

[0066] The connecting portion 202 is suitable for being installed in the battery pack 200, wherein the battery pack 200 is provided with a mounting flange 210, and the mounting flange 210 has a through hole that penetrates the mounting flange 210 in the up-down direction, and the connecting portion 202 is installed in the through hole, and the fixing portion 201 has a hydraulic cavity 204, and the hydraulic cavity 204 is connected with a plurality of pipelines 50. Specifically, the driving portion 20 of each hydraulic locking mechanism 10 is respectively connected with at least one pipeline 50, and the pressure medium in the pipeline 50 is suitable for flowing into the hydraulic cavity 204, and the accommodating space 205 is connected with the hydraulic cavity 204. The transmission rod 203 is movably arranged in the hydraulic cavity 204 and a part of the structure extends into the accommodating space 205. The transmission rod 203 is connected with the clamping structure 30. Figure 3 In the illustrated embodiment, the lower end of the transmission rod 203 is rotatably connected to the clamping structure 30. Pressure medium flows into and out of the hydraulic chamber 204, generating pressure within the hydraulic chamber 204 that drives the transmission rod 203, thereby driving the clamping structure 30 to reciprocate between a locked and unlocked position. The provision of the drive unit 20 enables control of the clamping structure 30, thereby enabling flexible control over the removal and installation of the battery pack 200, thus facilitating both removal and installation of the battery pack 200.

[0067] Furthermore, if Figure 3 、 Figure 4As shown, the clamping structure 30 can be movably installed in the accommodating space 205. Specifically, the clamping structure 30 can be rotatably installed in the accommodating space 205. When the clamping structure 30 is in the unlocked position, the clamping structure 30 is stored in the accommodating space 205, the clamping structure 30 does not contact the battery pack 200, and the battery pack 200 can move relative to the vehicle. When the clamping structure 30 is in the locked position, the clamping structure 30 extends out of the accommodating space 205 to be clamped with the battery pack 200, wherein the clamping structure 30 can be clamped with the bottom of the mounting flange 210 provided on the battery pack 200; refer to the attached Figure 2 、 Figure 3 As shown, mounting flanges 210 are provided on the left and right sides of the battery pack 200. The mounting flanges 210 can be mounted on the battery pack 200 by welding, screw connection, etc. The clamping structure 30 clamps the mounting flanges 210 fixedly connected to the battery pack 200, thereby achieving the installation and fixation of the battery pack 200, so that the battery pack 200 is installed at the lower end of the battery mounting bracket 300; when the battery pack 200 needs to be disassembled, the clamping structure 30 rotates to the retracted position and retracts into the accommodating space 205 of the connecting portion 202. At this time, the clamping structure 30 no longer clamps the mounting flanges 210. The mounting flange 210 and the battery pack 200 are both in an unconnected state. Since the battery pack 200 is hoisted to the lower end of the battery mounting bracket 300 by a quick disassembly structure, under the action of gravity, the mounting flange 210 and the battery pack 200 will be separated from the connecting piece, thereby completing the automatic disassembly of the battery pack 200; when the battery pack 200 needs to be installed, first the connecting piece is matched with the through hole of the mounting flange 210, and then the snap-fit ​​structure 30 is rotated to the extended position, and finally the snap-fit ​​structure 30 is snapped with the mounting flange 210 to fix the battery pack 200, thereby completing the assembly of the battery pack 200.

[0068] In some embodiments of the present invention, Figure 3 、 Figure 4 As shown, the drive unit 20 may further include an elastic member 206. The transmission rod 203 has a limiting wall, which is located within the hydraulic chamber 204. The elastic member 206 is located within the hydraulic chamber 204 and is installed between the limiting wall and the inner wall of the hydraulic chamber 204. The elastic member 206 is used to drive the transmission rod 203 to move the clamping structure 30 from the locked position to the unlocked position. When the pressure medium flows out of the drive unit 20, the elastic member 206 is adapted to drive the limiting wall so that the clamping structure 30, which is linked to the transmission rod 203, moves upward under the action of the elastic force after the pressure medium flows back to the storage unit. In this specific embodiment, the provision of the elastic member 206 can impart a certain upward restoring force to the limiting wall, so that when the limiting wall is not under pressure from the pressure medium, the elastic member 206 can return the transmission rod 203 to its pre-pressure position, thereby maintaining the clamping structure 30 in the unlocked position.

[0069] In some embodiments, the elastic member 206 may be a spring, a spring sheet, or other structures with elastic deformation capability, which is not specifically limited here.

[0070] In some embodiments, for example Figure 1 、 Figure 3 As shown, when the battery pack 200 needs to be installed, the control unit 60 can control the driving mechanism 40 to provide pressure medium to the driving part 20 through the pipeline 50, and the pressure medium can flow into the hydraulic chamber 204. The pressure medium in the hydraulic chamber 204 gradually fills the space and exerts pressure on the limiting wall in the hydraulic chamber 204, thereby driving the limiting wall to move. At the same time, the elastic member 206 between the transmission rod 203 and the inner wall of the transmission rod 203 is compressed, and the transmission rod 203 also moves with the movement of the limiting wall, and then drives the clamping structure 30 to rotate to the locking position, so that the clamping structure 30 is clamped with the mounting flange 210, thereby realizing the installation and fixation of the battery pack 200. When the battery pack 200 needs to be removed, the control unit 60 controls the multiple electromagnetic manual integrated valves 70 to open so that the pressure medium flows out from the hydraulic chamber 204 through the pipeline 50 to the storage unit. At this time, the limiting wall is no longer subjected to the pressure of the pressure medium, and the compressed elastic member 206 applies a thrust to the limiting wall, pushing the limiting wall back to the position before compression. At the same time, the pushed limiting wall drives the transmission rod 203 to move, thereby driving the clamping structure 30 to rotate to the unlocked position, so that the clamping structure 30 is disengaged from the mounting flange 210 and is no longer clamped and connected, thereby realizing the disassembly of the battery pack 200.

[0071] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the latching structure 30 includes at least one latching hook 301. A rotating shaft 302 is disposed within the receiving space 205, and the at least one latching hook 301 is rotatably mounted on the rotating shaft 302. In this embodiment, the latching hook 301 can rotate about the rotating shaft 302 to switch between a locked position and an unlocked position, thereby completing the removal and installation of the battery pack 200.

[0072] Furthermore, the hook 301 includes a driving section 303 and a hook head 304, which are respectively located on both sides of the radial direction of the rotating shaft 302. The driving section 303 is formed with a strip groove 305, and the end of the transmission rod 203 is formed with a transmission shaft 207 that cooperates with the strip groove 305. In this specific embodiment, the transmission shaft 207 is inserted into the strip groove of the driving part 20, thereby realizing the transmission connection between the transmission rod 203 and the hook 301, for example Figure 3As shown, the transmission shaft 207 is located above the rotating shaft 302 and is parallel to the rotating shaft 302. When the transmission rod 203 moves, the transmission shaft 207 moves synchronously between the two ends of the strip groove. Since the movement stroke of the piston is greater than the distance between the two ends of the strip groove, when the transmission shaft 207 moves from one end of the strip groove to the other end, it will continue to move forward with the movement of the transmission rod 203. At this time, the transmission shaft 207 will apply a thrust or pull force to the hook 301, so that the hook 301 rotates around the rotating shaft 302 and moves to a locked position or an unlocked position, thereby achieving the clamping fixation or disconnection of the battery pack 200, causing the battery pack 200 to automatically slide off, completing the rapid disassembly of the battery pack 200. This design is simple and ingenious, and can achieve rapid disassembly and assembly of the battery pack 200, saving time and improving disassembly and assembly efficiency.

[0073] Furthermore, the inner wall of the through hole is formed with a groove that cooperates with the hook head 304, or the hook head 304 is adapted to abut against the bottom wall of the mounting flange 210. The hook head 304 of the hook 301 and the mounting flange 210 can be mated using a groove or a direct abutment method. Both methods are applicable to different vehicle body structures, making it more applicable.

[0074] In some embodiments of the present invention, Figure 1 As shown, the battery quick release system 100 may further include: a collision detection unit 80. In some specific embodiments, the collision detection unit 80 may be constructed as a side collision acceleration sensor, and the side collision acceleration sensor may be installed in the B-pillar area on the left and right sides of the vehicle and other areas on both sides of the vehicle. The collision detection unit 80 is used to detect the collision state of the vehicle, and the collision detection unit 80 is communicatively connected with the control unit 60. When the vehicle is hit from the side, the collision detection unit 80 may detect the lateral acceleration of the vehicle body. The collision detection unit 80 may obtain the lateral acceleration of the vehicle body detected by the collision detection unit 80, thereby determining the degree of damage to the vehicle when it is hit from the side, and then the control unit 60 is adapted to control the corresponding electromagnetic manual integrated valve 70 to open or close according to the detection signal of the collision detection unit 80.

[0075] Specifically, when the lateral acceleration of the vehicle body is less than the preset acceleration threshold, the control unit 60 can determine that the vehicle is subjected to a slight collision or vibration, the degree of collision suffered by the vehicle is relatively light, and the battery pack 200 is not easily damaged. At this time, the control unit 60 can control the electromagnetic manual integrated valve 70 to remain closed, and the electromagnetic manual integrated valve 70 can block the pipeline 50, and then the clamping structure 30 can be maintained in the locked position to lock the battery pack 200, and the battery pack 200 will not fall off the vehicle. When the lateral acceleration of the vehicle body is greater than the preset acceleration threshold, the control unit 60 can determine that the vehicle has been severely collided and the battery pack 200 is likely to be damaged and catch fire. At this time, the control unit 60 can determine whether the battery pack 200 has caught fire after the vehicle has been collided based on the detection signal of the collision detection unit 80 and other data detected by the battery quick release system 100. When the control unit 60 determines that the battery pack 200 has caught fire after the vehicle has been collided, the control unit 60 can control the electromagnetic manual integrated valve 70 to open, and the electromagnetic manual integrated valve 70 can connect the pipeline 50, and then the clamping structure 30 can move from the locked position to the unlocked position to unlock the battery pack 200. After being unlocked, the battery pack 200 can fall from the vehicle, thereby reducing the impact of the battery pack 200 fire on other areas of the vehicle.

[0076] In some embodiments of the present invention, Figure 1 As shown, the battery quick disassembly system 100 may further include: a pressure detection unit 90. In some specific embodiments, the pressure detection unit 90 may be constructed as a pressure sensor, which may extend into the pipeline 50. The pressure detection unit 90 is used to detect the pressure in each pipeline 50, and the pressure detection unit 90 is communicatively connected with the control unit 60. The control unit 60 may obtain the pressure change in the corresponding pipeline 50 based on the detection signal of the pressure detection unit 90, so that the control unit 60 may determine whether the pressure medium in the corresponding pipeline 50 is leaking, and then the control unit 60 is suitable for controlling the corresponding electromagnetic manual integrated valve 70 to open or close according to the detection signal of the pressure detection unit 90.

[0077] Specifically, when the control unit 60 detects a decrease in pressure in the corresponding pipeline 50 through the pressure detection unit 90, the control unit 60 can control the electromagnetic manual integrated valve 70 corresponding to the pipeline 50 to open, and the driving mechanism 40 can add a small amount of pressure medium to the pipeline 50 to increase the pressure in the pipeline 50, thereby increasing the locking force of the hydraulic locking mechanism 10 and preventing the battery pack 200 from accidentally falling off the vehicle.

[0078] When the control unit 60 detects through the pressure detection unit 90 that the pressure in the corresponding pipeline 50 does not change significantly within a preset time after the pressure medium is replenished, the control unit 60 can determine that the pipeline 50 corresponding to the pressure detection unit 90 is not damaged and the pressure medium has not leaked. When the control unit 60 detects through the pressure detection unit 90 that the pressure in the corresponding pipeline 50 changes significantly within a preset time after the pressure medium is replenished, and the pressure drop in the pipeline 50 is not less than a preset pressure drop threshold, the control unit 60 can determine that the pipeline 50 is damaged and the pressure medium has leaked. At this time, the control unit 60 can control the electromagnetic manual integrated valve 70 corresponding to the pipeline 50 to reopen, allowing the pressure medium to flow out of the drive unit 20 of the hydraulic locking mechanism 10 corresponding to the damaged pipeline 50, thereby reducing the loss of the pressure medium in the battery quick release system 100. The hydraulic locking mechanism 10 connected to the normal pipeline 50 can lock the battery pack 200 to prevent the battery pack 200 from falling from the vehicle, thereby ensuring good operating stability of the vehicle. At the same time, the control unit 60 can report the abnormality to the occupants of the vehicle through the vehicle, so that the user can replace the damaged pipe 50 in time.

[0079] In addition, when the control unit 60 detects through the pressure detection unit 90 that the pressures in multiple pipelines 50 have all decreased, and the pressures in multiple pipelines 50 have all changed significantly within a preset time after the pressure medium is replenished, and the pressure drop in the pipelines 50 is not less than the preset pressure drop threshold, the control unit 60 can determine that multiple pipelines 50 are damaged and the pressure medium has leaked. At this time, the control unit 60 can control the electromagnetic manual integrated valves 70 corresponding to the multiple pipelines 50 to reopen, and the drive mechanism 40 can quickly fill the multiple pipelines 50 with pressure medium at the same time, and the speed at which the drive mechanism 40 injects pressure medium into the pipelines 50 is not less than the leakage speed of the pressure medium in the corresponding pipelines 50. In this way, the driving force of the drive unit 20 can be maintained, thereby preventing the battery pack 200 from falling off the vehicle immediately. The battery pack 200 will fall off the vehicle after the pressure medium is completely exhausted, that is, the time required for the battery pack 200 to fall off the vehicle is extended, which increases the user's reaction time to deal with abnormalities in the battery quick disassembly system 100.

[0080] Furthermore, the control unit 60 can be communicatively connected with the vehicle's controller (e.g., the vehicle's whole vehicle controller). When the battery quick-disassembly system 100 determines that multiple pipelines 50 are damaged through the detection signal of the pressure detection unit 90, the control unit 60 can send a battery quick-disassembly system 100 abnormality signal to the vehicle's controller. After receiving the abnormality signal, the vehicle's controller can send a warning to the driver through the vehicle's central control panel, instrument panel, and other devices, and the vehicle's controller can control the vehicle to automatically brake and / or turn on the hazard lights and / or sound the horn, etc., so as to ensure that the vehicle reduces its speed before the battery pack 200 falls, thereby avoiding the vehicle from losing power at high speed and causing serious traffic accidents. At the same time, the vehicle's controller can warn surrounding vehicles by controlling the vehicle to turn on the hazard lights, sound the horn, etc., thereby further reducing the probability of the vehicle being involved in a traffic accident.

[0081] In some embodiments of the present invention, Figure 1 As shown, the battery quick disassembly system 100 may further include: a temperature detection unit 110 and / or a smoke detection unit 120. In some specific embodiments, the temperature detection unit 110 may be constructed as a temperature sensor, and the temperature sensor is suitable for being arranged close to the battery pack 200. When the battery pack 200 is installed on the vehicle, the temperature detection unit 110 may detect the temperature of the battery pack 200, and the temperature detection unit 110 is communicatively connected with the control unit 60. The control unit 60 may obtain the temperature of the battery pack 200 based on the detection signal of the temperature detection unit 110, so that the control unit 60 may determine whether the battery pack 200 is on fire based on the temperature of the battery pack 200, and further the control unit 60 is suitable for controlling the corresponding electromagnetic manual integrated valve 70 to open or close according to the detection signal of the temperature detection unit 110.

[0082] Specifically, when the temperature of the battery pack 200 exceeds a preset temperature threshold, the control unit 60 can determine that the battery pack 200 is on fire. At this time, the control unit 60 can control the electromagnetic manual integrated valves 70 corresponding to multiple pipelines 50 to be opened. The electromagnetic manual integrated valves 70 can conduct the pipelines 50, and then the snap-fit ​​structure 30 can move from the locked position to the unlocked position to unlock the battery pack 200. After being unlocked, the battery pack 200 can fall from the vehicle, thereby reducing the impact of the battery pack 200 fire on other areas of the vehicle.

[0083] In some specific embodiments, the smoke detection unit 120 can be constructed as an infrared smoke sensor, and the infrared smoke sensor is suitable for being arranged near the battery pack 200. When the battery pack 200 is installed on the vehicle, the smoke detection unit 120 can detect whether there is smoke in the battery pack 200, and the smoke detection unit 120 is communicatively connected with the control unit 60. The control unit 60 can obtain whether there is smoke around the battery pack 200 based on the detection signal of the temperature detection unit 110, so that the control unit 60 can judge whether the battery pack 200 is on fire based on whether the battery pack 200 generates smoke, and then the control unit 60 is suitable for controlling the corresponding electromagnetic manual integrated valve 70 to open or close according to the detection signal of the smoke detection unit 120.

[0084] Specifically, when the amount of smoke around the battery pack 200 exceeds a preset smoke threshold, the control unit 60 can determine that the battery pack 200 is on fire. At this time, the control unit 60 can control the electromagnetic manual integrated valves 70 corresponding to multiple pipelines 50 to be opened. The electromagnetic manual integrated valves 70 can conduct the pipelines 50, and then the snap-fit ​​structure 30 can move from the locked position to the unlocked position to unlock the battery pack 200. After being unlocked, the battery pack 200 can fall from the vehicle, thereby reducing the impact of the battery pack 200 fire on other areas of the vehicle.

[0085] Furthermore, in some embodiments, the battery quick-disassembly system 100 may be provided with one of the temperature detection unit 110 and the smoke detection unit 120. In some preferred embodiments, the battery quick-disassembly system 100 may be provided with both the temperature detection unit 110 and the smoke detection unit 120. This allows the control unit 60 to more accurately determine whether the battery pack 200 is on fire, thereby reducing the probability that the battery quick-disassembly system 100 mistakenly locks the battery pack 200 due to an erroneous judgment by the control unit 60. Figure 1 As shown, the temperature detection unit 110 and the smoke detection unit 120 can be integrated together, which can reduce the number of components of the battery quick release system 100, thereby improving the assembly speed of the battery quick release system 100. At the same time, it can reduce the space occupied by the temperature detection unit 110 and the smoke detection unit 120 on the vehicle, making it easier to arrange the battery quick release system 100 on the vehicle.

[0086] Furthermore, the temperature detection unit 110 and the smoke detection unit 120 can be used in conjunction with other detection units of the battery quick release system 100. For example, the temperature detection unit 110 and the smoke detection unit 120 can be used in conjunction with the collision detection unit 80. When the control unit 60 determines that the vehicle has suffered a serious collision, the control unit 60 can jointly determine whether the battery pack 200 has caught fire after the vehicle was hit based on the detection signal of the collision detection unit 80, the detection signal of the temperature detection unit 110, and the detection signal of the smoke detection unit 120. When the control unit 60 determines that the battery pack 200 has caught fire after the vehicle was hit, the control unit 60 can control the electromagnetic manual integrated valve 70 to open, and the electromagnetic manual integrated valve 70 can connect the pipeline 50, and then the clamping structure 30 can move from the locked position to the unlocked position to unlock the battery pack 200. After being unlocked, the battery pack 200 can fall from the vehicle, thereby reducing the impact of the battery pack 200 fire on other areas of the vehicle.

[0087] The vehicle according to the embodiment of the present invention includes the battery quick-release system 100 described in the above embodiment. The battery quick-release system 100 is arranged on the vehicle, and the battery quick-release system 100 is used to fix the battery pack 200. By arranging multiple pipelines 50 between the storage unit and the driving unit 20 of the battery quick-release system 100, when some pipelines 50 of the battery quick-release system 100 are damaged and the pressure medium leaks, the remaining pipelines 50 can operate normally to avoid failure of the hydraulic locking mechanism 10. Compared with the prior art, the battery quick-release system 100 can reliably fix the battery pack 200, thereby preventing the battery pack 200 from falling from the vehicle, thereby improving the working reliability of the vehicle.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
