[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0042] The battery swapping device 100 of this utility model is described below with reference to the accompanying drawings. The battery swapping device 100 can be applied to battery swapping stations, but this application is not limited thereto. The battery swapping device 100 can be applied to other equipment that requires the installation of the battery swapping device 100. In this utility model, the application of the battery swapping device 100 to a battery swapping station is used as an example for illustration.

[0043] like Figures 1-6 As shown, the battery swapping device 100 according to the first aspect embodiment of the present invention includes: a support member 1, a positioning and locking mechanism 2, and a lifting member 3. The support member 1 is used to place the battery pack 200 and is provided with a first clearance hole. The lifting member 3 is provided on the support member 1 and is located on the side of the support member 1 away from the battery pack 200. The positioning and locking mechanism 2 is fixedly provided on the lifting member 3. The lifting member 3 is movable relative to the support member 1 along the first direction X of the battery swapping device 100 so that the positioning and locking mechanism 2 passes through the first clearance hole and extends into the mounting sleeve of the battery pack 200. The positioning and locking mechanism 2 includes a first limiting member 21, which has a locking position and an unlocking position. In the locking position, the first limiting member 21 is adapted to abut against the mounting sleeve to lock the positioning and locking mechanism 2 in the mounting sleeve. In the unlocking position, the positioning and locking mechanism 2 is adapted to move out of the mounting sleeve.

[0044] Specifically, with Figure 1Taking the placement direction of the battery swapping device 100 as an example, the support member 1 can be constructed as a support plate with a support plane on top. The battery pack 200 is placed on the support plane. Furthermore, the lifting member 3 can be constructed as a lifting plate. The lifting member 3 is located below the support member 1 and is parallel to the support member 1. The lifting member 3 can move up and down relative to the support member 1 along the first direction X. Furthermore, the battery swapping device 100 also includes a positioning and locking mechanism 2, wherein the positioning and locking mechanism 2 is fixedly connected to the lifting member 3. The fixed connection method includes, but is not limited to, bolt connection. With this configuration, the lifting member 3 can drive the positioning and locking mechanism 2 to move up and down relative to the support member 1 along the first direction X.

[0045] As a specific example, when the battery pack 200 needs to be disassembled for battery swapping, the battery swapping device 100 is driven to move to a suitable position, such as so that the support member 1 of the battery swapping device 100 is in contact with the battery pack 200 and the first clearance hole of the support member 1 is aligned with the mounting sleeve of the battery pack 200. Then, the lifting member 3 is driven to move upward along the first direction X, so that the positioning locking mechanism 2 passes through the first clearance hole and extends into the mounting sleeve of the battery pack 200, thereby achieving the positioning of the battery pack 200. Furthermore, the positioning and locking mechanism 2 includes a first limiting member 21, which can move to a locked position or an unlocked position. When the positioning and locking mechanism 2 extends into the mounting sleeve of the battery pack 200, it can also drive the first limiting member 21 to move to the locked position, thereby achieving abutment and engagement between the first limiting member 21 and the inner wall of the mounting sleeve to fix the positioning and locking mechanism 2 inside the mounting sleeve. With this configuration, the positioning and locking mechanism 2 can provide a pulling force to the battery pack 200 during disassembly, preventing jamming during disassembly and facilitating the disassembly of the battery pack 200. It should be noted that the positioning sleeve of the battery pack 200 can be provided with a slot, allowing the first limiting member 21 to engage in the slot to improve the fixing effect.

[0046] After the battery pack 200 is disassembled, the first limiting member 21 is driven to move to the unlocked position. The first limiting member 21 no longer abuts against the mounting sleeve. Then the lifting member 3 is driven to move downward along the first direction X, so that the positioning locking mechanism 2 moves out of the mounting sleeve and moves through the first clearance hole to the bottom of the support member 1 to prevent interference with the battery pack 200.

[0047] According to the battery swapping device 100 of this utility model embodiment, the battery swapping device 100 uses a positioning and locking mechanism 2 to position the battery pack 200 during the battery swapping process. The positioning and locking mechanism 2 is also provided with a first limiting member 21. When the first limiting member 21 is in the locked position, it can lock the battery pack 200, thereby providing a pulling force for the battery pack 200 during the disassembly process to prevent jamming during disassembly. At the same time, when the first limiting member 21 is in the unlocked position, it facilitates the separation of the positioning and locking mechanism 2 from the battery pack 200, thus meeting the disassembly requirements of the battery pack 200, reducing the risk of manual intervention, and improving the user experience.

[0048] In some embodiments of this utility model, such as Figures 3-5 As shown, the positioning and locking mechanism 2 further includes: a positioning member 22, which is fixed to the lifting member 3, and the side wall of the positioning member 22 is provided with a limiting hole 221. The first limiting member 21 is provided in the limiting hole 221 and is adapted to move along the axial direction of the limiting hole 221 to move to the locking position or the unlocking position.

[0049] Specifically, the positioning and locking mechanism 2 is fixedly installed on the lifting member 3 via the positioning element 22. It should be noted that the positioning element 22 can be directly installed on the lifting member 3, or indirectly installed on the lifting member 3 via other components. For example, ... Figure 4 As shown, a mounting block 25 is fixedly provided on the outer peripheral wall of the positioning component 22. The mounting block 25 is fixedly connected to the lifting component 3 by bolts or other fasteners, thereby realizing the fixed connection between the positioning component 22 and the lifting component 3. When the lifting component 3 moves up and down along the first direction X, the positioning component 22 can move up and down with the lifting component 3. When it is necessary to replace the battery pack 200, the lifting component 3 is driven to move upward along the first direction X, so that the positioning component 22 passes through the first clearance hole and extends into the mounting sleeve of the battery pack 200, thereby realizing the positioning of the battery pack 200.

[0050] Furthermore, such as Figure 5 As shown, the first limiting member 21 can be constructed as a spherical structure. The first limiting member 21 is disposed in the limiting hole 221 of the positioning member 22. The first limiting member 21 can move along the axial direction of the limiting hole 221 to move to the locked position or the unlocked position. It can be understood that when the first limiting member 21 is in the locked position, at least a part of the first limiting member 21 moves to the outside of the limiting hole 221 to abut against the inner sidewall of the mounting sleeve. When the first limiting member 21 is in the unlocked position, the first limiting member 21 is completely located in the limiting hole 221 to avoid abutting against the inner sidewall of the mounting sleeve, thereby stopping the abutment and limiting of the mounting sleeve. It should be noted that the locking position and unlocking position of the first limiting member 21 are not unique, as long as they can achieve locking and unlocking of the mounting sleeve.

[0051] Furthermore, when the positioning member 22 extends into the mounting sleeve of the battery pack 200, the first limiting member 21 is driven to move along the axial direction of the limiting hole 221 to the locking position, so that the first limiting member 21 abuts against the inner wall of the mounting sleeve to fix the positioning locking mechanism 2 inside the mounting sleeve. This provides a pulling force to the battery pack 200 during disassembly, preventing jamming during disassembly. After the battery pack 200 is disassembled, the first limiting member 21 is driven to move along the axial direction of the limiting hole 221 to the unlocking position, that is, the first limiting member 21 moves into the limiting hole 221 and no longer abuts against the inner wall of the mounting sleeve. The lifting member 3 is driven to move downward along the first direction X, so that the positioning member 22 moves out of the mounting sleeve and passes through the first clearance hole to the bottom of the support member 1 to prevent interference with the battery pack 200.

[0052] It should be noted that there can be multiple first limiting members 21, and multiple first limiting members 21 are all set in the corresponding limiting holes 221. The limiting holes 221 are arranged sequentially along the circumferential direction of the positioning member 22. This arrangement can provide greater pulling force to the battery pack 200 during the disassembly process, and further prevent jamming when the battery pack 200 is disassembled.

[0053] In some embodiments of this utility model, along the axial direction of the limiting hole 221, the end of the limiting hole 221 has a tapered limiting section, which is adapted to limit the first limiting member 21 to limit the first limiting member 21 within the limiting hole 221.

[0054] Specifically, the first limiting member 21 has a spherical structure, and the tapered limiting section can be constructed as an arc structure corresponding to the first limiting member 21. No specific restrictions are made here. The limiting hole 221 has a tapered limiting section at its end near the mounting sleeve. This tapered limiting section of the limiting hole 221 can limit the first limiting member 21, confining it within the limiting hole 221 and preventing it from falling out during operation. Furthermore, the end of the limiting hole 221 away from the mounting sleeve does not have a tapered limiting section, allowing the first limiting member 21 to be installed from this end within the limiting hole 221, facilitating its installation. The overall installation process is simple and convenient.

[0055] In some embodiments of this utility model, such as Figure 5 As shown, the positioning and locking mechanism 2 further includes a push rod 23. The positioning member 22 has a mounting groove 222 communicating with the limiting hole 221. At least a portion of the push rod 23 is movably disposed in the mounting groove 222, and the push rod 23 is adapted to drive the first limiting member 21 to move to the locking position so that the first limiting member 21 abuts against the inner wall of the mounting sleeve.

[0056] Specifically, such asFigure 5 As shown, the positioning member 22 has a mounting groove 222, which communicates with the limiting hole 221, allowing the first limiting member 21 to be installed from the mounting groove 222 into the limiting hole 221. The installation method is simple and convenient. Furthermore, a push rod 23 is provided within the mounting groove 222. The push rod 23 has a driving inclined surface 231, and the push rod 23 is movable along the axial direction of the mounting groove 222. Figure 5 Taking the orientation of the positioning and locking mechanism 2 as an example, during the process of the positioning member 22 extending into the mounting sleeve of the battery pack 200, the drive push rod 23 moves upward along the axial direction of the mounting groove 222, so that the drive inclined surface 231 of the push rod 23 drives the first limiting member 21 to move away from the mounting groove 222, that is, drives the first limiting member 21 to abut against the inner wall of the mounting sleeve to reach the locking position, thereby fixing the positioning and locking mechanism 2 in the mounting sleeve, which helps to prevent jamming during the disassembly of the battery pack 200; furthermore, when it is necessary to separate the positioning and locking mechanism 2 and the battery pack 200, the drive push rod 23 moves downward along the axial direction of the mounting groove 222, and the drive inclined surface 231 of the push rod 23 separates from the first limiting member 21. At the same time, refer to Figure 1 As shown, the drive positioning and locking mechanism 2 moves downward as a whole. Since the drive inclined surface 231 of the push rod 23 stops limiting the first limiting member 21, the first limiting member 21 moves towards the mounting groove 222 under the action of the inner wall of the mounting sleeve. That is, the first limiting member 21 no longer abuts against the inner wall of the mounting sleeve, thereby driving the positioning and locking mechanism 2 to move out of the mounting sleeve of the battery pack 200, realizing the disassembly of the positioning and locking mechanism 2 and the battery pack 200. The disassembly process is simple and reliable.

[0057] In some embodiments of this utility model, such as Figure 5 As shown, the positioning and locking mechanism 2 further includes: a second limiting member 24, a push rod 23 having a limiting groove 233, the second limiting member 24 being disposed in the limiting groove 233, and the push rod 23 being movable relative to the second limiting member 24 through the limiting groove 233.

[0058] Specifically, the second limiting member 24 can be constructed as a cylindrical structure. The second limiting member 24 is disposed within the limiting groove 233 of the push rod 23, and the second limiting member 24 can move relative to the push rod 23 within the limiting groove 233. The second limiting member 24 has a first limiting position and a second limiting position, so as to… Figure 5Taking the positioning and locking mechanism 2 shown as an example, the first limiting position is when the second limiting member 24 moves to the uppermost position relative to the limiting groove 233, and the second limiting position is when the second limiting member 24 moves to the lowermost position relative to the limiting groove 233. When the push rod 23 moves upward along the axial direction of the mounting groove 222, the second limiting member 24 moves towards the first limiting position relative to the limiting groove 233, so that the push rod 23 drives the first limiting member 21 to abut against the inner wall of the mounting sleeve to reach the locking position. When it is necessary to separate the positioning and locking mechanism 2 and the battery pack 200, the push rod 23 is driven to move downward along the axial direction of the mounting groove 222, and the second limiting member 24 moves towards the second limiting position relative to the limiting groove 233. When the second limiting member 24 moves to the second limiting position, the limiting groove 233 limits the second limiting member 24 to prevent the push rod 23 from continuing to move downward out of the mounting groove 222.

[0059] In some embodiments of this utility model, such as Figures 1-3 As shown, it also includes: a movable member 4, which is disposed on the lifting member 3 and located on the side of the lifting member 3 away from the supporting member 1. The movable member 4 is movable relative to the lifting member 3 along the second direction Y of the battery swapping device 100. The movable member 4 is adapted to drive the push rod 23 to move along the axial direction of the mounting groove 222, so as to move the first limiting member 21 to the locking position, wherein the first direction X is perpendicular to the second direction Y. That is to say, the battery swapping device 100 also includes a movable member 4, so as to... Figure 1 Taking the placement of the battery swapping device 100 as an example, the movable component 4 is set on the lifting component 3 and located below the lifting component 3. Figure 1 and Figure 5 As shown, the movable member 4 is movable relative to the lifting member 3 along the second direction Y. During the movement of the movable member 4, it drives the push rod 23 to move along the axial direction of the mounting groove 222, so as to drive the first limiting member 21 to move to the locking position through the push rod 23. For example, when the movable member 4 moves to the left along the second direction Y, it drives the push rod 23 to move upward so that the first limiting member 21 moves to the locking position. When the movable member 4 moves to the right along the second direction Y, it drives the push rod 23 to move downward so that the first limiting member 21 moves to the unlocking position. It should be noted that the movable member 4 can also adopt other driving methods. This is only an example and will not be described in detail.

[0060] In some embodiments of this utility model, such as Figure 6 As shown, the moving member 4 has a first guide portion 41, and the lifting member 3 has a second guide portion 31 that mates with the first guide portion 41. Through the guiding engagement of the first guide portion 41 and the second guide portion 31, the moving member 4 moves relative to the lifting member 3 along the second direction Y. Specifically, as... Figure 6As shown, the moving part 4 includes a first guide part 41, and the lower surface of the lifting part 3 is provided with a second guide part 31 that is fitted and assembled with the first guide part 41. Under the guidance of the first guide part 41 and the second guide part 31, the moving part 4 can move relative to the lifting part 3 along the second direction Y. For example, one of the first guide part 41 and the second guide part 31 can be constructed as a guide rail, and the other can be constructed as a slider. The guide rail extends along the second direction Y, and the slider can slide along the extension direction of the guide rail. Thus, through the cooperation of the first guide part 41 and the second guide part 31, the moving part 4 can be ensured to move smoothly in the second direction Y, avoiding directional deviation during the movement. Moreover, the guide rail and slider have simple structures and are easy to assemble.

[0061] In some embodiments of this utility model, such as Figures 1-3 As shown, the moving part 4 has a first inclined surface driving part 42, and the push rod 23 is provided with a first drive wheel 232 that is fitted and assembled with the first inclined surface driving part 42. Through the sliding cooperation of the first inclined surface driving part 42 and the first drive wheel 232, the moving part 4 is driven to move the push rod 23 along the axial direction of the mounting groove 222 when it moves relative to the push rod 23.

[0062] Specifically, such as Figure 1 As shown, the first inclined surface driving part 42 can move along the second direction Y following the moving part 4. During the left and right movement of the moving part 4 along the second direction Y, the first inclined surface driving part 42 selectively contacts the first driving wheel 232 of the push rod 23. For example, assuming that the first inclined surface driving part 42 does not contact the first driving wheel 232 at the initial position, the moving part 4 is driven along the second direction Y to make the first inclined surface driving part 42 gradually approach the first driving wheel 232. As the first inclined surface driving part 42 approaches, the first driving wheel 232 first contacts the lowest point of the inclined surface of the first inclined surface driving part 42, and as the first inclined surface driving part 42 moves, the first driving wheel 232 slides upward along the inclined surface of the first inclined surface driving part 42, thereby driving the push rod 23 to move upward along the axial direction of the mounting groove 222. Figure 5As shown, during the upward movement of push rod 23, the first limiting member 21 is driven to move away from the mounting groove 222, that is, the first limiting member 21 is driven to abut against the inner wall of the mounting sleeve to reach the locking position, thereby fixing the positioning and locking mechanism 2 inside the mounting sleeve; when the driving moving member 4 moves along the second direction Y to make the first inclined surface driving part 42 gradually move away from the first driving wheel 232, push rod 23 gradually loses the support of the first inclined surface driving part 42, and push rod 23 moves downward along the inclined surface of the first inclined surface driving part 42 under its own gravity. The drive ramp 231 of the push rod 23 stops limiting the first limiting member 21, and the first limiting member 21 can move to the unlocked position. At this time, the drive positioning and locking mechanism 2 moves downward as a whole, which can remove it from the mounting sleeve of the battery pack 200, realizing the disassembly of the positioning and locking mechanism 2 and the battery pack 200. Thus, through the cooperation of the first ramp drive part 42 and the first drive wheel 232, the locking and unlocking of the positioning and locking mechanism 2 are realized. The structure is simple and the drive is reliable. It is relatively easy to add this function to old battery swapping equipment, which is conducive to saving costs.

[0063] In some embodiments of this utility model, such as Figure 6 As shown, the moving member 4 has a second inclined surface driving part 43, and the support member 1 is provided with a second driving wheel 11 that is fitted and assembled with the second inclined surface driving part 43. By sliding the second inclined surface driving part 43 and the second driving wheel 11 together, the moving member 4 is driven to move the lifting member 3 relative to the support member 1 along the first direction X when it moves relative to the support member 1.

[0064] Specifically, such as Figure 1 As shown, the moving part 4 is provided with a second inclined surface driving part 43. The inclined surface of the second inclined surface driving part 43 has a certain angle with the support part 1. The support part 1 is provided with a second drive wheel 11 that is fitted and assembled with the second inclined surface driving part 43. The second drive wheel 11 is located below the inclined surface of the second inclined surface driving part 43 to support the moving part 4. Furthermore, the lifting part 3 is installed above the moving part 4. Therefore, the second drive wheel 11 can provide a certain support for the lifting part 3. During the process of the moving part 4 moving left and right along the second direction Y, the second inclined surface driving part 43 moves along the second direction Y with the moving part 4. At the same time, the second inclined surface driving part 43 slides relative to the second drive wheel 11. With this configuration, the linear motion of the moving part 4 relative to the support part 1 is converted into the relative lifting motion of the moving part 4 and the support part 1, that is, the lifting part 3 is driven to move relative to the support part 1 along the first direction X. Furthermore, the positioning and locking mechanism 2 is fixedly connected to the lifting part 3, thereby driving the positioning and locking mechanism 2 to move up and down relative to the support part 1 along the first direction X.

[0065] It should be noted that, in order to realize the positioning and locking function of the positioning and locking mechanism 2, the moving part 4 can be simultaneously provided with a first inclined surface driving part 42 and a second inclined surface driving part 43, so as to realize the overall movement of the positioning and locking mechanism 2 and the movement of the first limiting part 21 inside the positioning and locking mechanism 2. As a specific example, assuming that in the initial position, the first inclined surface driving part 42 is not in contact with the first driving wheel 232, and the second driving wheel 11 is located at the lowest point of the inclined surface of the second inclined surface driving part 43, such as... Figure 1 and Figure 3 As shown, when the second drive wheel 11 moves to the highest position relative to the second inclined drive section 43, that is, when the lifting member 3 moves to the highest position, the first drive wheel 232 also moves to the top of the first inclined drive section 42.

[0066] When the battery pack 200 needs to be disassembled for battery replacement, the driving moving part 4 moves along the second direction Y, so that the lifting part 3 moves upward along the first direction X through the relative sliding of the second inclined driving part 43 and the second driving wheel 11, so that the positioning locking mechanism 2 passes through the first clearance hole and extends into the mounting sleeve of the battery pack 200, thereby achieving the positioning of the battery pack 200. As the moving part 4 moves, the first inclined driving part 42 gradually approaches the first driving wheel 232. As the first inclined driving part 42 approaches, the first driving wheel 232 first contacts the lowest point of the inclined surface of the first inclined driving part 42, and as the first inclined driving part 42 moves, the first driving wheel 232 slides upward along the inclined surface of the first inclined driving part 42, thereby driving the push rod 23 to move upward, so as to drive the first limiting part 21 to abut against the inner wall of the mounting sleeve to reach the locking position, thereby positioning and locking the mechanism. The mechanism 2 is fixed inside the mounting sleeve of the battery pack 200. After the battery pack 200 is disassembled, the driving moving part 4 moves in the opposite direction along the second direction Y, so that the first inclined driving part 42 gradually moves away from the first driving wheel 232. The push rod 23 moves downward along the inclined surface of the first inclined driving part 42 under its own gravity. The driving inclined surface 231 of the push rod 23 stops limiting the first limiting part 21. The first limiting part 21 can move to the unlocked position. At the same time, the lifting part 3 and the moving part 4 drive the second inclined driving part 43 to slide relative to the second driving wheel 11 and move downward under its own gravity. At this time, the positioning locking mechanism 2 moves downward as a whole and moves out of the mounting sleeve of the battery pack 200, realizing the disassembly of the positioning locking mechanism 2 and the battery pack 200. Thus, the synchronous positioning and locking function of the positioning locking mechanism 2 is realized, which greatly simplifies the structural complexity and ensures reliable operation.

[0067] In some embodiments of this utility model, such as Figure 1As shown, it also includes a drive component 5, which is fixed to the lifting component 3 and is adapted to drive the moving component 4 to move relative to the lifting component 3 along the second direction Y. Specifically, the drive component 5 can be a drive motor or a drive cylinder. The drive component 5 is fixedly installed on the lower surface of the lifting component 3. The fixed installation method includes, but is not limited to, bolt connection. The drive component 5 is fixedly connected to the moving component 4 through a transmission component 51, so that the transmission component 51 drives the moving component 4 to move left and right relative to the lifting component 3 along the second direction Y. With this configuration, the drive component 5 helps to improve the automation level of the battery swapping device 100, thereby realizing automatic battery swapping of the battery swapping device 100 and improving the user experience.

[0068] In some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the support member 1 has a third guide portion 12, and the lifting member 3 has a fourth guide portion 32 that mates with the third guide portion 12. Through the guiding engagement of the third guide portion 12 and the fourth guide portion 32, the lifting member 3 moves relative to the support member 1 along the first direction X. Specifically, as... Figure 6 As shown, the support member 1 has a third guide portion 12, and the lifting member 3 has a fourth guide portion 32 that cooperates with the third guide portion 12. Under the guidance of the third guide portion 12 and the fourth guide portion 32, the lifting member 3 can move relative to the support member 1 along the first direction X. For example, one of the third guide portion 12 and the fourth guide portion 32 can be constructed as a guide sleeve, and the other can be constructed as a guide pin. The guide pin extends along the first direction X and can slide along the guide sleeve. Thus, through the cooperation of the third guide portion 12 and the fourth guide portion 32, the lifting member 3 can be ensured to move smoothly in the first direction X, avoiding directional deviation during the movement, thereby ensuring the smoothness of the movement of the positioning and locking mechanism 2. Moreover, the guide pin and the guide sleeve have simple structures and are easy to assemble.

[0069] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 6 As shown, it also includes: an unlocking structure 6, which is fixed to the lifting member 3. The lifting member 3 is adapted to drive the unlocking structure 6 to move to a first position or a second position. When the unlocking structure 6 is in the first position, it is adapted to lock or unlock the battery pack 200. The support member 1 has a support surface that supports the battery pack 200. When the unlocking structure 6 is in the second position, it is located on the side of the support surface away from the battery pack 200.

[0070] Specifically, the battery swapping device 100 also includes an unlocking structure 6, which is fixedly installed on the lifting member 3 so that the unlocking structure 6 can move up and down along the first direction X with the lifting member 3. The lifting member 3 drives the unlocking structure 6 to move to a first position or a second position. The first position is where the lifting member 3 drives the positioning and locking mechanism 2 to position and lock the battery pack 200. After the lifting member 3 moves to the first position, the unlocking structure 6 is suitable for locking or unlocking the battery pack 200. For example, when it is necessary to disassemble the battery pack 200, the unlocking structure 6 is driven to lock the battery pack 200 to achieve the disassembly of the battery pack 200. After the battery pack 200 is disassembled, for example, when it is necessary to place the battery pack 200 back into the charging dock... In the electrical equipment, the unlocking structure 6 is driven to unlock the battery pack 200 to allow the battery pack 200 to be placed. Then, the lifting component 3 drives the unlocking structure 6 to move from the first position to the second position. At this time, the positioning locking mechanism 2 no longer locks and fixes the battery pack 200. When the unlocking structure 6 is in the second position, it is located on the side of the support surface away from the battery pack 200, that is, it is located below the support plane. This can avoid interference between the battery pack 200 and the unlocking structure 6 during the transfer, which would cause the transfer of the battery pack 200 to fail. At the same time, during the replacement of the battery pack 200, locking the battery pack 200 by the unlocking structure 6 can also prevent the battery pack 200 from falling.

[0071] By providing the aforementioned battery swapping device 100, the battery swapping device 100 uses the positioning and locking mechanism 2 to position the battery pack 200 during the battery swapping process. The positioning and locking mechanism 2 is also provided with a first limiting member 21. When the first limiting member 21 is in the locked position, it can lock the battery pack 200, thereby providing a pulling force for the battery pack 200 during the disassembly process to prevent jamming during disassembly. At the same time, when the first limiting member 21 is in the unlocked position, it facilitates the separation of the positioning and locking mechanism 2 from the battery pack 200, thus meeting the disassembly requirements of the battery pack 200, reducing the risk of manual intervention, and improving the user experience.

[0072] According to the embodiment of the present utility model, the battery swapping station is equipped with the above-mentioned battery swapping device 10. During the battery swapping process, the battery swapping device 100 uses the positioning and locking mechanism 2 to position the battery pack 200. The positioning and locking mechanism 2 is also equipped with a first limiting member 21. When the first limiting member 21 is in the locked position, it can lock the battery pack 200, thereby providing a pulling force for the battery pack 200 during the disassembly process, preventing jamming during disassembly. At the same time, when the first limiting member 21 is in the unlocked position, it facilitates the separation of the positioning and locking mechanism 2 from the battery pack 200, meeting the disassembly requirements of the battery pack 200, reducing the risk of manual intervention, and improving the user experience.
