Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] The battery box mounting assembly, battery swapping device, and vehicle provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, in some embodiments of this application, a battery box mounting assembly is proposed, including: a locking mechanism 1 and a support member 2. The support member 2 is used to mount the battery box 3, and the locking mechanism 1 is disposed on the support member 2. The locking mechanism 1 includes a locking member 11, a mounting base 12, a transmission arm 13, and a driving member 14. The locking member 11 includes a first end 111 and a second end 112 disposed opposite to each other, and a connecting portion 113 located between the first end 111 and the second end 112. The first end 111 is rotatably connected to the mounting base 12. One end of the transmission arm 13 is rotatably connected to the connecting portion 113, and the other end of the transmission arm 13 is connected to the driving member 14. The driving member 14 is used to drive the transmission arm 13 to move, so as to drive the locking member 11 to rotate relative to the mounting base 12, so as to lock or unlock the battery box 3.

[0037] In this embodiment, one end of the transmission arm 13 is rotatably connected to the connecting part 113, and the other end of the transmission arm 13 is connected to the driving member 14. The first end 111 of the locking member 11 is rotatably connected to the mounting base 12. The driving member 14 drives the transmission arm 13 to move, and the transmission arm 13 drives the locking member 11 to rotate relative to the mounting base 12. In this way, the transmission arm 13 increases the distance between the driving member 14 and the rotation center of the locking member 11, so that the locking member 11 has a larger torque when locking, and the locking effect is better, which improves the reliability of the battery box mounting assembly. At the same time, the stroke of the locking member 11 is smaller, making the structure of the entire locking mechanism 1 more compact.

[0038] It should be explained that the drive component 14 can be a cylinder, hydraulic cylinder, electric actuator, etc. Those skilled in the art can configure it according to actual needs, and this application does not impose any limitations on this. The drive component 14 is preferably a cylinder, in which case the power source for the cylinder can be provided by onboard compressed air.

[0039] Understandably, the first end 111 of the locking member 11 is rotatably connected to the mounting base 12. This can be because the first end 111 is provided with a rotating pin, the mounting base 12 is provided with a rotating hole, and the rotating pin is rotatably connected to the rotating hole; or the first end 111 is provided with a rotating hole, the mounting base 12 is provided with a rotating pin, and the rotating pin is rotatably connected to the rotating hole.

[0040] It should be explained that the locking member 11 includes a first end 111 and a second end 112 disposed opposite to each other, and a connecting part 113 located between the first end 111 and the second end 112. The first end 111 is used to be rotatably connected to the mounting base 12, and the second end 112 is used to abut against the battery box 3 to lock the battery box 3. The connecting part 113 is used to be rotatably connected to the transmission arm 13, so that the driving member 14 drives the transmission arm 13 to move. The transmission arm 13 drives the locking member 11 to rotate relative to the mounting base 12 through the connecting part 113, thereby realizing the locking or unlocking of the battery box 3.

[0041] like Figure 2 As shown, in some embodiments of this application, a third rotating shaft 4 is also included. The first end 111 is rotatably connected to the mounting base 12 via the third rotating shaft 4, thereby facilitating installation and simplifying the processing of the locking member 11, reducing the cost of the battery box mounting assembly. The first end 111 and the mounting base 12 are provided with through holes that mate with the third rotating shaft 4. Of course, both ends of the third rotating shaft 4 are also provided with limiting components, such as washers, gaskets, and pins, to ensure the stability of the connection.

[0042] like Figure 7 and Figure 8 As shown, in some embodiments of this application, the battery box 3 includes a bracket 31 and an abutment block 32. The abutment block 32 is disposed on the bracket 31, and the second end 112 of the locking member 11 abuts against the surface of the abutment block 32 to lock the battery box 3. The number of abutment blocks 32 corresponds to the number of locking mechanisms 1. For example, if there are 2, 3, 4, or 5 locking mechanisms 1, the number of abutment blocks 32 should be the same as the number of locking mechanisms 1.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the mounting base 12 is provided with a receiving space 120, the receiving space 120 has an opening 121, and the locking member 11 is disposed in the receiving space 120; the locking member 11 has a first state and a second state. When the locking member 11 is in the first state, the second end 112 is exposed outside the opening 121 to lock the battery box 3; when the locking member 11 is in the second state, the second end 112 is retracted into the receiving space 120 to release the locking of the battery box 3.

[0044] In this embodiment of the application, by providing a receiving space 120 in the mounting base 12, the locking member 11 is placed in the receiving space 120, which further reduces the overall size of the locking mechanism 1. At the same time, it can protect the rotating parts of the locking member 11 and reduce the risk of the locking mechanism 1 being damaged and failing due to external force.

[0045] In practical applications, the first state of the locking member 11 is the locked state. When the locking member 11 is in the locked state, the second end 112 of the locking member 11 is exposed in the opening 121 and can lock the battery box 3. The second state of the locking member 11 is the unlocked state. When the locking member 11 is in the unlocked state, the second end 112 of the locking member 11 is stored in the receiving space 120, thereby releasing the lock on the battery box 3 so as to facilitate the replacement of the battery box 3.

[0046] It should be explained that the opening 121 is located on the side of the mounting base 12 facing the abutment block 32 of the battery box 3, so that the second end 112 of the locking member 11 can abut against the abutment block 32 after extending out of the opening 121.

[0047] Understandably, the locking element 11 is configured as an arc-shaped structure, so that the second end 112 can be extended from the opening 121 by rotation, and the first end 111 is rotatably connected to the mounting base 12.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of this application, the transmission arm 13 includes a first connecting rod 131 and a first rotating shaft 132. The connecting part 113 is provided with a slot 1131. One end of the first connecting rod 131 extends into the slot 1131 and is rotatably connected to the connecting part 113 through the first rotating shaft 132. The other end of the first connecting rod 131 is rotatably connected to the driving member 14.

[0049] In this embodiment, one end of the first connecting rod 131 extends into the slot 1131 and is rotatably connected to the connecting part 113 via the first rotating shaft 132. That is, the first rotating shaft 132 passes through the groove wall of the slot 1131 on the connecting part 113 and also passes through the first connecting rod 131, forming a hinge. The other end of the first connecting rod 131 is rotatably connected to the driving member 14, so that the driving member 14 drives the other end of the first connecting rod 131 to move, thereby causing one end of the first connecting rod 131 to rotate in the slot 1131 and causing the locking member 11 to rotate around the first end 111, so that the second end 112 extends out of the opening 121 or rotates back into the accommodating space 120.

[0050] It should be explained that the connecting part 113 is provided with a slot 1131, and a through hole corresponding to the first rotating shaft 132 is provided on the groove wall of the slot 1131, so that the first connecting rod 131 passes through the through hole on the groove wall of the slot 1131 and the through hole of the first connecting rod 132, so as to realize the rotatable connection of the first connecting rod 131 to the connecting part 113. Of course, the two ends of the first rotating shaft 132 are also provided with limiting members, such as washers, gaskets and pins, to ensure the stability of the connection.

[0051] Please refer to Figure 2 and Figure 3 In some embodiments of this application, when the locking member 11 is in the first state, the first link 131 at least partially abuts against the groove wall of the slot 1131 to restrict the rotation of the locking member 11.

[0052] In this embodiment, when the locking member 11 is in the first state, that is, when the locking member 11 is in the locked state, the first connecting rod 131 at least partially abuts against the groove wall of the slot 1131, thereby forming a "dead point" between the first connecting rod 113 and the locking member 11, so that the locking member 11 can no longer rotate, ensuring the possibility of the locking member 11 failing to lock the battery box 3, and improving the reliability of the battery box mounting assembly.

[0053] It should be explained that the "dead point" specifically refers to the first link 131 and the locking member 11 being in a certain angle of a limited position. At this time, the first link 131 restricts the position of the locking member 11 through the slot 1131, that is, the locking member 11 is restricted by the first link 131, and the locking force on the battery box 3 will not decrease.

[0054] like Figure 4 and Figure 5 As shown, in some embodiments of this application, the transmission arm 13 includes a first rotating shaft 132, a second connecting rod 133 and a third connecting rod 134. The second connecting rod 133 and the third connecting rod 134 are disposed on both sides of the locking member 11. One end of the second connecting rod 133 and the third connecting rod 134 is rotatably connected to the connecting part 113 through the first rotating shaft 132, and the other end of the second connecting rod 133 and the third connecting rod 134 is rotatably connected to the driving member 14.

[0055] In this embodiment, the second link 133 and the third link 134 are located on both sides of the locking member 11. One end of the second link 133 and the third link 134 is rotatably connected to the connecting part 113 via the first rotating shaft 132. That is, the first rotating shaft 132 passes through one end of the second link 133 and the third link 134 and passes through the connecting part 113 to form a hinge. The other end of the second link 133 and the third link 134 is rotatably connected to the driving member 14. Thus, the driving member 14 drives the other end of the second link 133 and the third link 134 to move, and then drives the locking member 11 to rotate relative to the mounting base 12 via the first rotating shaft 132. The second link 133 and the third link 134 can ensure that the locking member 11 is subjected to more balanced force and will not be biased. At the same time, the structure has higher strength and better reliability.

[0056] In specific applications, the connecting part 113 of the second link 133, the third link 134 and the locking member 11 is provided with a through hole that mates with the first rotating shaft 132, so that the first rotating shaft 132 passes into the through hole to realize the rotational connection of the connecting part 113 of the second link 133, the third link 134 and the locking member 11. Of course, the two ends of the first rotating shaft 132 are also provided with limiting members, such as washers, gaskets and pins, to ensure the stability of the connection.

[0057] like Figures 1-6 As shown, in some embodiments of this application, the locking mechanism 1 further includes a second rotating shaft 15 and a roller 16; the mounting base 12 includes two oppositely arranged side plates 122, and the two side plates 122 are provided with corresponding sliding grooves 123. The output end 141 of the driving member 14 is connected to the other end of the transmission arm 13 through the second rotating shaft 15. The second rotating shaft 15 is rotatably connected to the sliding groove 123 through the roller 16. The movement direction of the output end 141 is consistent with the extension direction of the sliding groove 123.

[0058] In this embodiment, the output end 141 of the drive member 14 is connected to the other end of the transmission arm 13 via a second rotating shaft 15. That is, the second rotating shaft 15 passes through the output end 141 of the drive member 14 and the other end of the transmission arm 13, forming a hinge. The second rotating shaft 15 is tactilely connected to the slide groove 123 via a roller 16. The roller 16 is sleeved on the outer circumferential surface of the second rotating shaft 15 and tactilely connected to the slide groove 123. The movement direction of the output end 141 is consistent with the extension direction of the slide groove 123. Thus, when the output end 141 of the drive member 14 drives the other end of the transmission arm 13 to move, the second rotating shaft 15 and the roller 16 roll in the slide groove 123, which can guide and limit the movement of the transmission arm 13. This ensures that when the transmission arm 13 drives the locking member 11 to rotate, it conforms to the preset movement trajectory, so as to achieve the effect of locking the battery box 3. At the same time, the roller 16 rolls in the slide groove 123, which makes the movement smoother and prevents jamming.

[0059] It should be explained that the movement direction of the output end 141 of the drive component 14 is consistent with the extension direction of the slide 123, that is, the movement direction of the output end 141 is parallel to the extension direction of the slide 123. For example, the output end 141 moves in the vertical direction, and the extension direction of the slide 123 is also set in the vertical direction, thereby ensuring smooth movement.

[0060] In specific applications, there are two rollers 16, corresponding to the slide grooves 123, which are respectively fitted onto the two ends of the second rotating shaft 15.

[0061] like Figures 1-5 As shown, in some embodiments of this application, the drive member 14 is installed on the side of the mounting base 12 away from the battery box 3, thereby utilizing the space between the mounting base 12 and the support member 2 to make the locking mechanism 1 more compact and occupy less area.

[0062] like Figure 6 As shown, in some embodiments of this application, the battery box mounting assembly further includes a base 19, which is disposed on the support member 2. The base 19 is spaced apart from the mounting base 12, and the slide groove 123 extends obliquely toward the base 19. The drive member 14 is mounted on the base 19. This allows for configuration according to actual conditions, so that the locking mechanism 1 can adapt to different working conditions, thereby improving the applicability of the battery box mounting assembly.

[0063] It needs to be explained that, such as Figure 6 As shown, the extension direction of the slide groove 123 forms a certain angle with the vertical direction, and the movement direction of the output end 141 of the drive member 14 is consistent with the extension direction of the slide groove 123.

[0064] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments of this application, the battery box mounting assembly further includes a sensing element 17, which is disposed on the mounting base 12 and is used to sense the position of the locking element 11.

[0065] In this embodiment of the application, by setting the sensing element 17, the position of the locking element 11 can be sensed, which improves the operability of the locking mechanism 1. There is no need for manual detection of the locking status of the battery box 3. The sensing element 17 can monitor the state of the locking element 11 to ensure that the locking element 11 is in the locked state when the vehicle is driving, thereby ensuring the safety of vehicle driving.

[0066] In specific applications, the sensing element 17 can be a proximity switch, limit switch, Hall sensor, etc. The position of the locking element 11 when it is in the locked state is different from the position of the locking element 11 when it is in the unlocked state.

[0067] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments of this application, a support base 171 is also included. The support base 171 is detachably connected to the mounting base 12, and the sensing element 17 is disposed between the support base 171 and the mounting base 12, thereby installing the sensing element 17 through the support base 171, which improves convenience.

[0068] In some embodiments of this application, the sensing element 17 includes a Hall sensor, which is disposed on the mounting base 12 near the opening 121. A magnet is disposed in the second end 112 of the locking element 11, and the Hall sensor is used to detect the second end 112 of the locking element 11.

[0069] A magnet is an object that can generate a magnetic field, and a Hall sensor is used to sense the strength of the magnetic field generated by the magnet. When the position of the magnet relative to the Hall sensor changes, the strength of the magnetic field sensed by the Hall sensor also changes, and the output signal of the Hall sensor changes accordingly. Therefore, the position of the second end 112 of the locking member 11 can be determined based on the output signal of the Hall sensor.

[0070] like Figure 9 As shown, in some embodiments of this application, multiple locking mechanisms 1 are provided, and the multiple locking mechanisms 1 are arranged at intervals around the support member 2.

[0071] In this embodiment of the application, by providing multiple locking mechanisms 1 at intervals around the support member 2, the locking effect of the battery box mounting assembly on the battery box 3 is improved, preventing the battery box 3 from moving during vehicle operation and improving vehicle safety.

[0072] In specific applications, the number of locking mechanisms 1 can be set to any value such as 1, 2, 3, 4, 5, 6, etc. Those skilled in the art can set it according to their needs, and this application does not impose any restrictions on it.

[0073] like Figure 9 As shown, in some embodiments of this application, the battery box mounting assembly further includes a guide 18, which is disposed on the side of the support 2 facing the battery box 3.

[0074] In this embodiment, by providing a guide 18 on the side of the support 2 facing the battery box 3, the installation of the battery box 3 is made more convenient, and the ease of use of the battery box installation assembly is improved.

[0075] In specific applications, the number of guide members 18 can be set to multiple, and multiple guide members 18 can be arranged around the support member 2 at intervals.

[0076] The following is based on Figures 1-3 Taking the locking mechanism 1 shown as an example, the working principle of the locking mechanism 1 will be briefly introduced:

[0077] When the locking member 11 is switched from the second state (unlocked state) to the first state (locked state), the output end 141 of the control drive member 14 extends. At this time, the roller 16 on the second rotating shaft 15 connected to the output end 141 of the drive member 14 rolls along the lower end of the slide groove 123 to the upper end of the slide groove 123. When the second rotating shaft 15 moves upward, it drives the connection end of the first connecting rod 131 and the connection part 113 of the locking member 11 to move upward, so that the first connecting rod 131 drives the locking member 11 to rotate downward around the first end 111. The second end 112 extends out of the opening 121 and abuts against the abutting block 32 on the battery box 3, thus locking the battery box 3. At this time, the sensing member 17 sends the position signal to the host computer, and the host computer knows that the locking is completed by judging the position.

[0078] When the locking member 11 is switched from the first state (locked state) to the second state (unlocked state), the actions of the driving member 14, the transmission arm 13, and the locking member 11 are reversed, thereby retracting the second end 112 from the opening 121 and accommodating it in the receiving space 120 to avoid the battery box 3.

[0079] The host computer specifically refers to the vehicle's central control system. When the central control system detects that the vehicle needs to replace the battery box 3, after the vehicle arrives at the designated location of the battery swapping station, the central control system issues a command to the control component. The control component controls the drive component 14 to perform corresponding actions to release the locking mechanism 1 from locking the battery box 3.

[0080] In some embodiments of this application, a battery swapping device is also proposed, including a battery box 3 and a battery box mounting assembly as described in any of the above embodiments, wherein the battery box 3 is mounted on a support member 2.

[0081] In this embodiment, the battery box mounting assembly includes a locking mechanism 1 and a support member 2. The support member 2 is used to mount the battery box 3, and the locking mechanism 1 is disposed on the support member 2. The locking mechanism 1 includes a locking member 11, a mounting base 12, a transmission arm 13, and a driving member 14. The locking member 11 includes a first end 111, a second end 112 disposed opposite to each other, and a connecting portion 113 located between the first end 111 and the second end 112. The first end 111 is rotatably connected to the mounting base 12. One end of the transmission arm 13 is rotatably connected to the connecting portion 113, and the other end of the transmission arm 13 is connected to the driving member 14. The driving member 14 is used to drive the transmission arm 13 to move, so as to drive the locking member 11 to rotate relative to the mounting base 12, so as to lock or unlock the battery box 3. This increases the distance between the drive member 14 and the rotation center of the locking member 11 by the transmission arm 13, resulting in a larger torque when the locking member 11 locks, a better locking effect, and improved reliability of the battery box mounting assembly; at the same time, the stroke of the locking member 11 is smaller, making the structure of the entire locking mechanism 1 more compact.

[0082] In some embodiments of this application, a vehicle is also proposed, including a battery box mounting assembly as described in any of the above embodiments, or a battery swapping device as described in any of the above embodiments.

[0083] In this embodiment, the battery box mounting assembly includes a locking mechanism 1 and a support member 2. The support member 2 is used to mount the battery box 3, and the locking mechanism 1 is disposed on the support member 2. The locking mechanism 1 includes a locking member 11, a mounting base 12, a transmission arm 13, and a driving member 14. The locking member 11 includes a first end 111, a second end 112 disposed opposite to each other, and a connecting portion 113 located between the first end 111 and the second end 112. The first end 111 is rotatably connected to the mounting base 12. One end of the transmission arm 13 is rotatably connected to the connecting portion 113, and the other end of the transmission arm 13 is connected to the driving member 14. The driving member 14 is used to drive the transmission arm 13 to move, so as to drive the locking member 11 to rotate relative to the mounting base 12, so as to lock or unlock the battery box 3. This increases the distance between the drive member 14 and the rotation center of the locking member 11 by the transmission arm 13, resulting in a larger torque when the locking member 11 locks, a better locking effect, and improved reliability of the battery box mounting assembly; at the same time, the stroke of the locking member 11 is smaller, making the structure of the entire locking mechanism 1 more compact.
