Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a battery swapping engineering vehicle. Background Technology

[0002] Driven by factors such as energy conservation, environmental protection, and low operating costs, the electrification of construction machinery is an inevitable trend. Electric construction machinery is characterized by high power consumption, long required continuous operating time, and inadequate refueling facilities for off-peak conditions. This is especially true for tracked excavators, which have lower travel speeds and smaller operating ranges, making refueling particularly difficult. Therefore, rapid battery swapping for various electric construction machinery used in mining, port, municipal, and tunnel construction scenarios has become a pressing issue that technical personnel in the field need to address and optimize.

[0003] In existing technologies, battery swapping for construction machinery can be achieved using cranes with mobile capabilities. Specifically, the crane can lift depleted batteries out of the battery compartment and install fully charged batteries inside. However, existing lifting equipment only handles the lifting of batteries; other vehicles or manual labor are required for battery transport and site loading / unloading.

[0028] Beneficial effects:

[0029] This utility model provides a battery swapping vehicle comprising a vehicle body, a main platform, and a swapping assembly. The main platform is mounted on the vehicle body and includes an upper loading tray and an lower loading tray. The upper loading tray holds fully charged batteries to be swapped onto the construction machinery, while the lower loading tray holds depleted batteries removed from the construction machinery. The main platform can rotate relative to the vehicle body, thereby adjusting the position of the upper and lower loading trays relative to the construction machinery, so that either tray faces the machinery. The swapping assembly includes a transfer mechanism mounted on the main platform and a gripping mechanism mounted on the transfer mechanism. The gripping mechanism is driven by the transfer mechanism to move, enabling it to grip depleted batteries in the construction machinery's battery compartment and transfer them to the lower loading tray, or to grip fully charged batteries on the upper loading tray and transfer them to the construction machinery's battery compartment.

[0030] Specifically, when using this battery swapping vehicle for battery swapping operations, firstly, after placing a fully charged battery on the loading tray, multiple outriggers extend to reliably support and stabilize the vehicle. The swapping equipment then moves to one side of the vehicle, with its battery compartment facing the unloading tray, and opens the compartment to expose the depleted battery to be replaced. At this point, the unloading tray of the main platform faces the battery compartment. Subsequently, the transfer mechanism drives the gripping mechanism to move, allowing the gripping mechanism to pick up the depleted battery from the battery compartment, continue moving, and finally transfer the depleted battery to the unloading tray, reliably placing it on the tray. After replacing the depleted battery, the main platform rotates relative to the vehicle body, adjusting its orientation so that the loading tray faces the battery compartment. Once the main platform position is adjusted, the transfer mechanism continues to drive the gripping mechanism to move, allowing the gripping mechanism to pick up the fully charged battery from the loading tray and transfer it into the battery compartment, thus installing the fully charged battery. Once the fully charged battery is installed and its placement is confirmed to be accurate, the battery compartment is closed, completing the battery swapping process for the construction machinery. Using this method, the battery swapping vehicle enables rapid and reliable battery replacement for construction machinery. Both the fully charged battery to be replaced and the depleted battery are transported directly within the vehicle, eliminating the need for manual or other intervention in battery transport after replacement. Furthermore, the entire replacement process minimizes manual handling, reducing labor costs and effectively improving battery swapping efficiency. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0046] This embodiment provides a battery swapping vehicle. (Refer to...) Figures 1 to 5 As shown, the battery swapping vehicle includes a vehicle body 1, a main platform 2, and a swapping assembly 3. The main platform 2 is mounted on the vehicle body 1 and has a loading tray 21 and a unloading tray 22. The swapping assembly 3 includes a transfer mechanism 31 and a gripping mechanism 32. The transfer mechanism 31 is mounted on the main platform 2, and the gripping mechanism 32 is mounted on the transfer mechanism 31. The main platform 2 can rotate relative to the vehicle body 1, so that the loading tray 21 or the unloading tray 22 of the main platform 2 faces the engineering machinery 100 to be swapped. The transfer mechanism 31 is used to drive the gripping mechanism 32 to move, so that the gripping mechanism 32 grabs the depleted battery 200 in the battery 200 compartment of the engineering machinery 100 and transfers it to the unloading tray 22, or grabs the fully charged battery 200 on the loading tray 21 and transfers it to the battery 200 compartment of the engineering machinery 100.

[0047] This embodiment also provides a battery swapping method for the battery swapping vehicle. This method utilizes the aforementioned battery swapping vehicle, and the beneficial effects of this method on the vehicle will be described in detail below.

[0048] Reference Figures 1 to 6 As shown, the battery swapping method includes the following steps:

[0049] S100 After the fully charged battery 200 is placed on the loading base 21, the vehicle body 1 is kept fixed. The construction machinery 100 waiting to replace the battery 200 drives to one side of the vehicle body 1, and the battery 200 compartment faces the unloading base 22, and then the battery 200 compartment is opened.

[0050] S200, the transfer mechanism 31 drives the gripping mechanism 32 to move, so that the gripping mechanism 32 grips the depleted battery 200 in the battery 200 compartment and transfers it to the unloading base 22.

[0051] S300 and main platform 2 rotate on vehicle body 1 so that loading base 21 faces battery 200 compartment;

[0052] S400, the transfer mechanism 31 drives the gripping mechanism 32 to move, so that the gripping mechanism 32 grips the fully charged battery 200 on the loading base 21 and transfers it into the battery 200 compartment.

[0053] After confirming that the fully charged battery 200 is placed in the correct position, close the battery 200 compartment to complete the battery swap.

[0054] In this embodiment, the battery swapping vehicle includes a vehicle body 1, a main platform 2, and a swapping assembly 3. The main platform 2 is mounted on the vehicle body 1 and includes a loading tray 21 and a unloading tray 22. The loading tray 21 holds a fully charged battery 200 to be swapped onto the engineering machinery 100, while the unloading tray 22 holds a depleted battery 200 removed from the engineering machinery 100. The main platform 2 can rotate relative to the vehicle body 1, thereby adjusting the position of the loading tray 21 and the unloading tray 22 relative to the engineering machinery 100, so that either the loading tray 21 or the unloading tray 22 faces the engineering machinery 100. The swapping assembly 3 includes a transfer mechanism 31 mounted on the main platform 2 and a gripping mechanism 32 mounted on the transfer mechanism 31. The gripping mechanism 32 is driven by the transfer mechanism 31 to move, so that the gripping mechanism 32 can grip the depleted battery 200 in the battery 200 compartment of the construction machinery 100 and transfer it to the unloading base tray 22, or grip the fully charged battery 200 on the loading base tray 21 and transfer it to the battery 200 compartment of the construction machinery 100.

[0055] Specifically, when using this battery swapping vehicle for battery swapping operations, firstly, after placing a fully charged battery 200 on the loading tray 21, multiple outriggers of the vehicle body 1 extend to reliably support and fix the vehicle body 1. The engineering machinery 100 to be swapped then moves to one side of the vehicle body 1, with its battery 200 compartment facing the unloading tray 22, and opens the battery 200 compartment to expose the depleted battery 200 to be swapped. At this time, the side of the unloading tray 22 of the main platform 2 faces the battery 200 compartment. Subsequently, the transfer mechanism 31 drives the gripping mechanism 32 to move, causing the gripping mechanism 32 to grab the depleted battery 200 from the battery 200 compartment, continue moving, and finally transfer the depleted battery 200 to the unloading tray 22, reliably placing the depleted battery 200 on the unloading tray 22. After replacing the depleted battery 200, the main platform 2 rotates relative to the vehicle body 1, adjusting its orientation so that the loading tray 21 faces the battery 200 compartment. Once the main platform 2 is positioned, the transfer mechanism 31 continues to drive the gripping mechanism 32, causing it to grab the fully charged battery 200 from the loading tray 21 and transfer it into the battery 200 compartment, thus installing the fully charged battery 200. After the fully charged battery 200 is installed and its placement is confirmed to be accurate, the battery 200 compartment is closed, completing the entire battery swapping operation for the construction machinery 100. Using this method, the battery swapping vehicle can quickly and reliably replace the battery 200 in the construction machinery 100. Both the fully charged battery 200 to be replaced and the depleted battery 200 are transported via the vehicle body 1, avoiding the need for manual or other interventions in battery transportation after replacement. In addition, the entire replacement process reduces manual handling, thus reducing manpower consumption and effectively improving the efficiency of battery swapping operations.

[0056] For example, when multiple construction machines 100 need to have their batteries swapped, the above operation can be repeated.

[0057] For example, the main platform 2 may have multiple loading bases 21 and unloading bases 22, which can hold multiple fully charged batteries 200 and depleted batteries 200 at one time.

[0058] In this embodiment, the transfer mechanism 31 includes a first transfer component, a second transfer component, a third transfer component, and a fourth transfer component connected in sequence. The first transfer component is mounted on the main platform 2, and the gripping mechanism 32 is mounted on the fourth transfer component. The first transfer component drives the second transfer component to rotate on the main platform 2; the second transfer component drives the third transfer component to move vertically; the third transfer component drives the fourth transfer component to move horizontally; and the fourth transfer component drives the gripping mechanism 32 to rotate. Specifically, the transfer mechanism 31 enables the gripping mechanism 32 to revolve, rotate, move vertically up and down, and move horizontally forward and backward, ensuring flexible movement of the gripping mechanism 32.

[0059] Specifically, in this embodiment, the first transfer assembly includes a first base 311, a first rotating part 312, and a first driving member 313. The first base 311 is fixed to the main platform 2, the first rotating part 312 is rotatably connected to the first base 311, and the first driving member 313 is used to drive the first rotating part 312 to rotate around the first base 311. The second transfer assembly includes at least two first arm sections 314 nested sequentially in a vertical direction, and also includes a second driving member 315. The outermost first arm section 314 is fixed to the first rotating part 312, and the second driving member 315 is used to drive the first arm sections 314 to rotate together. The third transfer assembly includes at least two second arm sections 316 nested sequentially in the horizontal direction, and also includes a third drive member. The outermost second arm section 316 is fixedly connected to the innermost first arm section 314. The third drive member is used to drive the extension and retraction between the second arm sections 316. The fourth transfer assembly includes a second base 317, a second rotating part 318 and a fourth drive member 319. The second base 317 is located on the innermost second arm section 316, the gripping mechanism 32 is located on the second rotating part 318, and the fourth drive member 319 is used to drive the second rotating part 318 to rotate on the second base 317.

[0060] Specifically, the first transfer assembly is similar to a rotary mechanism. The first base 311 is fixed to the main platform 2, and the first rotating part 312 is rotatably connected to the first base 311. The first driving member 313 enables relative rotation between the first rotating part 312 and the first base 311, thereby controlling all components above the first transfer assembly and the gripping mechanism 32 to rotate around an axis, i.e., realizing the revolution of the gripping mechanism 32. The axis of rotation of the first rotating part 312 relative to the first base 311 is perpendicular to the main platform 2. When the main platform 2 is in a horizontal state, this axis extends in the vertical direction. Optionally, the first driving member 313 can be a motor. The motor housing is fixed to the first base 311, and the motor output shaft is connected to the first rotating part 312. Rotation of the motor output shaft can drive the first rotating part 312 to rotate relative to the first base 311.

[0061] Specifically, in the second transfer assembly, at least two first arm sections 314 extend vertically and are nested sequentially. The second drive member 315 can drive the first arm sections 314 to extend and retract, so that the inner first arm section 314 can extend and retract relative to the outer first arm section 314 among two adjacent first arm sections 314. This drives all components above the second transfer assembly and the gripping mechanism 32 to achieve vertical movement, i.e., realizes the vertical lifting and lowering movement of the gripping mechanism 32. Optionally, the second drive member 315 is configured as a telescopic cylinder. The cylinder body of the telescopic cylinder is fixed to the outermost first arm section 314, and the cylinder rod of the telescopic cylinder is fixed to the innermost first arm section 314. The extension and retraction of the cylinder rod relative to the cylinder body of the telescopic cylinder realizes the lifting and lowering control between the first arm sections 314.

[0062] For example, in this embodiment, the number of first arm segments 314 is set to two.

[0063] Specifically, in the third transfer assembly, at least two second arm sections 316 extend horizontally and are nested sequentially. The third drive member can drive the extension and retraction of the second arm sections 316, so that the inner second arm section 316 can extend and retract relative to the outer second arm section 316 among two adjacent second arm sections 316, thereby driving the fourth transfer mechanism 31 and the gripping mechanism 32 to achieve horizontal movement, that is, to realize the horizontal forward and backward movement of the gripping mechanism 32. Optionally, the third drive member is set as a telescopic cylinder, with the cylinder body of the telescopic cylinder fixed to the outermost second arm section 316 and the cylinder rod of the telescopic cylinder fixed to the innermost second arm section 316. The extension and retraction of the cylinder rod of the telescopic cylinder relative to the cylinder body can realize the lifting and lowering control between the second arm sections 316.

[0064] For example, in this embodiment, the number of second arm segments 316 is set to two.

[0065] Specifically, the fourth transfer assembly is similar to a rotary mechanism. The second base 317 is fixed to the innermost second arm section 316, i.e., the telescopic end of the second arm section 316. The second rotating part 318 is rotatably connected to the second base 317. The relative rotation between the second rotating part 318 and the second base 317 can be achieved through the fourth driving member 319, thereby controlling the gripping mechanism 32 to rotate around its axis, i.e., realizing the rotation of the gripping mechanism 32. The axis of rotation of the second rotating part 318 relative to the second base 317 is perpendicular to the main platform 2. When the main platform 2 is in a horizontal state, this axis extends in the vertical direction. Optionally, the fourth driving member 319 can be a motor. The motor housing is fixed to the second base 317, and the motor output shaft is connected to the first rotating part 312 through a transmission assembly. The rotation of the motor output shaft can drive the first rotating part 312 to rotate around the first base 311 through the transmission assembly.

[0066] Specifically, in steps S200 to S400, the specific movement process of the transfer mechanism 31 is as follows:

[0067] Step S200 specifically involves: the third driving member driving the second arm sections 316 to extend outward relative to each other, thereby driving the gripping mechanism 32 to move horizontally above the battery 200 compartment, so that the gripping mechanism 32 is directly opposite the depleted battery 200 in the battery 200 compartment. The gripping mechanism 32 then grips the depleted battery 200. During this process, the angle of the gripping mechanism 32 can be adjusted by controlling the rotation of the second rotating part 318 relative to the second base 317, thereby finely adjusting the relative position between the gripping mechanism 32 and the depleted battery 200 to achieve effective gripping of the depleted battery 200. Subsequently, the second driving member 315 drives the first arm sections 314 to extend outward relative to each other, thereby driving the gripping mechanism 32 to rise vertically to the target height, and then gripping the depleted battery 200 out of the battery 200 compartment. Subsequently, the third drive unit drives the second arm sections 316 to retract relative to each other. During this process, the gripping mechanism 32 maintains its grip on the depleted battery 200, thereby horizontally moving the depleted battery 200 from above the battery 200 compartment and placing it above the unloading base 22 of the main platform 2. Next, the second drive unit 315 drives the first arm sections 314 to retract relative to each other, thereby driving the gripping mechanism 32 to descend vertically and placing the gripped depleted battery 200 above the unloading base 22. During this process, the angle of the gripping mechanism 32 can be adjusted by controlling the rotation of the second rotating part 318 relative to the second base 317, thereby finely adjusting the relative position between the depleted battery 200 and the unloading base 22 to achieve precise placement of the depleted battery 200.

[0068] Next, the installation of the fully charged battery 200 is carried out. Step S300 involves rotating the main platform 2 relative to the vehicle body 1 and adjusting its orientation so that the loading base 21 faces the battery 200 compartment. Step S400 involves the second drive member 315 driving the first arm sections 314 to extend outwards relative to each other, thereby driving the gripping mechanism 32 to rise vertically to the target height. The first drive member 313 controls the first rotating part 312 to rotate relative to the first base 311, causing the gripping mechanism 32 to move above the loading base 21. Subsequently, the second drive member 315 drives the first arm sections 314 to retract relative to each other, thereby driving the gripping mechanism 32 to descend vertically and grip the fully charged battery 200 located on the loading base 21. During this process, the angle of the gripping mechanism 32 can be adjusted by controlling the rotation of the second rotating part 318 relative to the second base 317, thereby finely adjusting the relative position between the gripping mechanism 32 and the loading base 21 to achieve precise gripping of the fully charged battery 200. Subsequently, the second drive member 315 drives the first arm sections 314 to extend outward relative to each other, thereby driving the gripping mechanism 32 to rise vertically to the target height, and then gripping the depleted battery 200 onto the loading base 21. Then, the third drive member drives the second arm sections 316 to extend outward relative to each other, during which the gripping mechanism 32 maintains its grip on the fully charged battery 200, thereby moving the fully charged battery 200 horizontally from above the loading base 21 and moving it above the battery 200 compartment. Next, the second drive member 315 drives the first arm sections 314 to retract outward relative to each other, thereby driving the gripping mechanism 32 to descend vertically, and then placing the gripped fully charged battery 200 into the battery 200 compartment. During this process, the angle of the gripping mechanism 32 can be adjusted by controlling the rotation of the second rotating part 318 relative to the second base 317, thereby finely adjusting the relative position between the fully charged battery 200 and the battery 200 compartment to achieve precise placement of the fully charged battery 200.

[0069] In this embodiment, a rotary drive 11 is provided between the main platform 2 and the vehicle body 1. The rotary drive 11 is used to drive the main platform 2 to rotate on the vehicle body 1. Specifically, the rotary drive 11 can be configured as a motor. The motor housing is fixed to the vehicle body 1, and the output shaft of the motor is connected to the main platform 2. The rotation of the motor output shaft can drive the main platform 2 to rotate on the vehicle body 1.

[0070] For example, the loading base 21 and the unloading base 22 are located at opposite ends of the main platform 2, and the transfer mechanism 31 is located between the loading base 21 and the unloading base 22. Each time the main platform 2 rotates, it can rotate 180° to change direction and switch between the loading base 21 and the unloading base 22.

[0071] In this embodiment, each first arm segment 314 is provided with a wiring hole 3141, and a reinforcing rib is provided on the outer edge of the wiring hole 3141. Specifically, the reinforcing rib includes a first reinforcing rib 31411 and a second reinforcing rib 31412. The first reinforcing rib 31411 protrudes from the outer edge of the wiring hole 3141, and the second reinforcing rib 31412 is horizontally attached to the outer edge of the wiring hole 3141. A third reinforcing rib 31413 is provided circumferentially on the first arm segment 314. The third reinforcing rib 31413 enables the connection between the first reinforcing rib 31411 and the first arm segment 314, as well as between the second reinforcing rib 31412 and the first arm segment 314, further enhancing the strength of the first arm segment 314 and improving its reliability. The wiring hole 3141 is provided for external wire harnesses to pass through into the first arm segment 314 and connect with related equipment inside the first arm segment 314, avoiding interference with the wiring.

[0072] Furthermore, the second base 317 and the second arm segment 316 are hinged together via a hinge shaft 3110. By providing the hinge shaft 3110, a hinged relationship is established between the second base 317 and the second arm segment 316, allowing the third transfer assembly and the fourth transfer assembly to swing relative to each other, further improving the mobility of the gripping mechanism 32. For example, the hinge shaft 3110 is connected to a damping element, which provides damping for the swinging connection between the second base 317 and the second arm segment 316. The damping element can be a mechanical friction device or a hydraulic cylinder damping device.

[0073] In this embodiment, the gripping mechanism 32 includes a base plate 321, a lifting plate 322, a hook 323, and a lifting drive. The base plate 321 is disposed on the transfer mechanism 31, the lifting plate 322 is disposed below the base plate 321, and the lifting plate 322 is connected to the base plate 321 via the lifting drive. The hook 323 is disposed on the lifting plate 322 and is used to hook the battery 200. The lifting drive is used to drive the lifting plate 322 to rise and fall above the base plate 321. Specifically, the lifting drive drives the lifting plate 322 to descend relative to the base plate 321, causing the hook 323 to descend and ultimately connect with the connection structure on the battery 200. For example, the connection structure on the battery 200 can be configured as a lifting lug, and the hook 323 can be hooked to the lifting lug.

[0074] Specifically, in this embodiment, the lifting drive includes a drive cylinder 3241, a first rope 3242, and a second rope 3243. The first end of the first rope 3242, the first end of the second rope 3243, and the cylinder body of the drive cylinder 3241 are all fixed to the first end of the base plate 321. The base plate 321 is provided with a first pulley 3251, a second pulley 3252, and a third pulley 3253 in sequence from the first end to the second end. The cylinder rod of the drive cylinder 3241 is provided with a fourth pulley 3254 and a fifth pulley 3255. The second end of the first rope 3242 is connected to the first end of the lifting plate 322 after passing through the fourth pulley 3254 and the first pulley 3251 in sequence. The second end of the second rope 3243 is connected to the second end of the lifting plate 322 after passing through the fifth pulley 3255, the second pulley 3252, and the third pulley 3253 in sequence. Specifically, the first end of the base plate 321 is at the same end as the first end of the lifting plate 322, and the second end of the base plate 321 is at the same end as the second end of the lifting plate 322. Specifically, the fourth pulley 3254 and the fifth pulley 3255 are set to have different diameters. This arrangement allows the first rope 3242 and the second rope 3243 to be misaligned, preventing mutual interference.

[0075] Specifically, the cylinder rod of the drive cylinder 3241 extends outward relative to the cylinder body, causing the second end of the first rope 3242 and the second end of the second rope 3243 to gradually approach the substrate 321, that is, the lifting plate 322 gradually approaches the substrate 321 and finally fits against the substrate 321; the cylinder rod of the drive cylinder 3241 retracts outward relative to the cylinder body, causing the second end of the first rope 3242 and the second end of the second rope 3243 to gradually move away from the substrate 321, that is, the lifting plate 322 gradually moves away from the substrate 321, so that the lower part of the lifting plate 322 allows the carding member to approach the battery 200 and finally connect with the battery 200.

[0076] For example, multiple sets of lifting drive components can be provided at intervals, preferably two sets, so as to ensure that the lifting plate 322 is subjected to uniform tension and to prevent the lifting plate 322 from overturning.

[0077] For example, both the first rope 3242 and the second rope 3243 are made of steel wire rope, which is highly reliable and not easily broken.

[0078] In this embodiment, the base plate 321 is provided with a guide rail 3211 along the extension and retraction direction of the drive cylinder 3241, and the cylinder rod of the drive cylinder 3241 is provided with a guide plate 3212, which is slidably connected to the guide rail 3211. Specifically, the sliding cooperation between the guide plate 3212 and the guide rail 3211 further strictly limits the extension and retraction direction of the cylinder rod of the drive cylinder 3241, preventing deviation of the extension and retraction direction of the cylinder, thereby ensuring the reliability and effectiveness of the control over the raising and lowering of the first rope 3242 and the second rope 3243, and ensuring the reliable raising and lowering of the lifting plate 322.

[0079] In this embodiment, the drive cylinder 3241, the first pulley 3251, the second pulley 3252, the third pulley 3253, the fourth pulley 3254, the fifth pulley 3255, the guide plate 3212, and the guide rail 3211 are all disposed in the base plate 321. The base plate 321 has a first through hole and a second through hole. The first through hole allows the second end of the first rope 3242 to pass through, and the second through hole allows the second end of the second rope 3243 to pass through.

[0080] In this embodiment, a guide positioning head 328 is provided on the side of the lifting plate 322 facing away from the substrate 321. Multiple guide positioning heads 328 are provided to jointly provide contact positioning for the battery 200. Specifically, the multiple guide positioning heads 328 can jointly form a limiting area. During the descent of the lifting plate 322, the upper end of the battery 200 enters the limiting area, and the guide positioning head 328 contacts the corresponding side wall of the battery 200, i.e., the battery 200 is inserted into the limiting area, ensuring a reliable and stable position between the lifting plate 322 and the battery 200.

[0081] In this embodiment, the substrate 321 is provided with a guide sleeve 326, and the lifting plate 322 is provided with a limiting head 327 on the side facing the substrate 321. The limiting head 327 is used to insert into the guide sleeve 326. Specifically, as the lifting plate 322 rises, the limiting head 327 gradually approaches the guide sleeve 326 and can finally insert into the guide sleeve 326. After the limiting head 327 is inserted into the guide sleeve 326, the lifting plate 322 and the substrate 321 remain relatively fixed. This allows for relative fixation between the lifting plate 322 and the substrate 321 after the battery 200 is grasped, preventing the lifting plate 322 from moving. Before grasping the battery 200, the limiting head 327 can disengage from the guide sleeve 326, allowing the lifting plate 322 to swing relative to the substrate 321. This allows for fine adjustment of the position of the lifting plate 322, ensuring that the lifting plate 322 faces the battery 200 for easy grasping and connection.

[0082] For example, a position sensor 329 is also provided on the side of the lifting plate 322 facing away from the base plate 321. The position sensor 329 is used to detect the position of the battery 200 grasped by the lifting plate 322. When the hook 323 of the lifting plate 322 hooks the battery 200 into place, the position sensor 329 can detect the position signal of the battery 200, ensuring that the battery 200 is grasped in place.
