Description

Technical Field

[0001] This utility model relates to the field of vehicle battery swapping technology, and in particular to a battery swapping device and a battery swapping station including the same. Background Technology

[0002] In existing battery swapping stations, battery packs are installed and removed from electric vehicles using swapping equipment, which is then used to transport the battery packs. This equipment requires mechanisms for movement within the station, adjustments in the X, Y, and Z directions during swapping, and a battery pack unlocking mechanism. This results in a complex mechanical structure that is prone to malfunctions.

[0003] In addition, for battery swapping stations that use multiple battery compartments, each battery compartment needs a separate battery swapping device for battery retrieval and delivery. Furthermore, multiple battery swapping devices need to have adjustment mechanisms in the XYZ directions and battery pack unlocking mechanisms, which leads to a certain degree of functional redundancy and generates additional costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of existing battery swapping equipment, which has a complex mechanical structure, is prone to failure, and has a high cost, and to provide a battery swapping equipment and a battery swapping station including the same.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A battery swapping device for replacing battery packs of electric vehicles at a battery swapping station, comprising:

[0007] A battery swapping platform, the battery swapping platform including an unlocking mechanism, the unlocking mechanism being used to unlock the locking mechanism of the battery pack;

[0008] A battery transport device capable of transporting battery packs to or away from the battery swapping platform;

[0009] An adjustment device is available to drive the battery swapping platform and / or the unlocking / unlocking mechanism to move in the X-axis and / or Y-axis directions.

[0010] A lifting device is used to drive the battery swapping platform to move in the Z-axis direction.

[0011] In this solution, the aforementioned structure is adopted. The battery swapping equipment includes a battery transport device and a battery swapping platform. The battery pack transfer is carried out on the battery transport device, which only has the function of battery transfer and does not participate in the loading and unloading of battery packs. The loading and unloading function of battery packs is integrated into the battery swapping platform. The adjustment device can adjust the battery swapping platform to make fine adjustments for alignment or to adapt to different models of battery packs. By separating the transport and loading / unloading functions into two separate devices, the structures of each become simpler, and the number of mechanisms with repetitive functions is reduced, which helps to reduce the cost of the entire equipment.

[0012] Preferably, the battery transport device includes a vertical through-hole. When the battery swapping platform loads or unloads the battery pack, the battery pack and the battery swapping platform are located on the upper and lower sides of the battery transport device, respectively, and the battery swapping platform unlocks or unlocks the battery pack through the through-hole.

[0013] In this solution, the above structure allows the battery swapping platform to directly contact the battery transport device from below through the port to complete the locking and unlocking process, without the need for additional position adjustments, thus shortening the battery swapping process.

[0014] Preferably, the battery swapping platform can be driven to rise by the lifting device and extend into the opening to contact the battery pack above the battery transport device.

[0015] In this solution, the above-mentioned structure is adopted. The battery transport device is a frame structure with a hollow center so that the battery swapping platform can extend into and contact the battery pack during battery swapping to complete the loading and unloading of the battery pack, which is more convenient.

[0016] Preferably, the battery swapping platform includes a first positioning part, and the battery transport device is correspondingly provided with a second positioning part, wherein the first positioning part can be aligned and cooperate with the second positioning part when the battery swapping platform is raised.

[0017] In this solution, the above structure enables the battery transport device to be positioned with the battery swapping platform during assembly operations, allowing them to be positioned with each other without additional position adjustments when handing over battery packs, thus saving steps.

[0018] Preferably, the lifting device can drive the battery swapping platform and the battery transport device to move synchronously in the Z-axis direction and drive the battery pack to move synchronously in the Z-axis direction.

[0019] In this solution, the aforementioned structure is adopted, with the battery swapping platform and battery transport device aligned and interconnected. During battery swapping operations, they rise and fall synchronously, forming a unified battery pack carrier to jointly achieve battery pack loading and unloading. This avoids the cumbersome process of transferring the battery pack from the battery transport device to the battery swapping equipment and then having the swapping equipment carry the battery pack, and also reduces the possibility of errors caused by increased stress and battery pack displacement.

[0020] Preferably, the battery swapping platform includes a support frame that can contact and support the battery transport device and drive the battery transport device to move synchronously when the battery swapping platform is raised.

[0021] Preferably, when the support frame contacts the battery transport device, the upper surface of the battery swapping platform is higher than the upper surface of the battery transport device.

[0022] In this solution, the above structure is adopted. When the bottom surface of the battery transport device contacts the support beam of the battery swapping platform, there is a certain step difference between the upper surface of the battery transport device and the battery swapping platform. The purpose of the step difference is to ensure that the battery transport device does not affect the unlocking process when the unlocking screw module is unlocked.

[0023] Preferably, the adjustment device is capable of driving the battery transport device and the lifting device to move along the X-axis and / or Y-axis.

[0024] In this solution, the aforementioned structure is adopted, with the battery swapping platform and battery transport device aligned and interconnected. During battery swapping operations, they rise and fall synchronously, forming a unified battery pack carrier to facilitate loading and unloading. During loading and unloading, an adjustment device can simultaneously adjust both components, ensuring the electric positions of the battery swapping platform and battery transport device are aligned with the locking structure of the battery pack by the unlocking device. After the battery swapping is completed, the position of the battery transport device is adjusted to return it to the correct travel track.

[0025] Preferably, the adjustment device includes an X-axis adjustment section and a Y-axis adjustment section, wherein the X-axis adjustment section and / or the Y-axis adjustment section are disposed on the battery swapping platform or the lifting device;

[0026] The X-axis adjustment unit can drive the battery swapping platform and / or the lifting device to move along the X-axis direction;

[0027] The Y-axis adjustment unit can drive the battery swapping platform and / or the lifting device to move along the Y-axis direction.

[0028] In this solution, the aforementioned structure is adopted, and the adjustment device is divided into an X-axis adjustment section capable of adjusting the position in the X-axis direction and a Y-axis adjustment section capable of adjusting the position in the Y-axis direction. These two sections can respectively adjust the position of the battery swapping equipment or the unlocking / unlocking mechanism. They can be positioned in different locations to avoid structural conflicts. Furthermore, the two adjustment sections can be configured to drive the lifting device to move the entire battery swapping equipment, or they can be configured to drive only the unlocking / unlocking mechanism to perform corresponding movements.

[0029] Preferably, the X-axis adjustment part is an adjustment platform, and the lifting device is disposed on the adjustment platform and can move along the X-axis direction;

[0030] and / or

[0031] The Y-axis adjustment unit is mounted on the battery swapping platform and drives the unlocking / unlocking device to move along the Y-axis.

[0032] In this solution, the aforementioned structure is adopted, with the two motion modes positioned in two different locations. This minimizes the conflict between their motion mechanisms. The X-axis adjustment unit can drive the lifting device, allowing it to adjust the overall movement of the battery swapping platform. The Y-axis adjustment unit only needs to adjust the position of the unlocking mechanism, making it compact and easy to integrate into the battery swapping platform.

[0033] Preferably, the unlocking mechanism includes a first mechanism and a second mechanism, and the Y-axis adjustment part includes a first adjustment part capable of driving the first mechanism to move and / or a second adjustment part capable of driving the second mechanism to move;

[0034] The first adjustment unit can drive the first mechanism to move closer to or away from the second mechanism; and / or the second adjustment unit can drive the second mechanism to move closer to or away from the first mechanism.

[0035] In this solution, the above structure is adopted. The unlocking mechanism has two parts. The Y-axis adjustment part can adjust the relative position of these two parts, so that it can be adapted to more battery packs.

[0036] Preferably, the battery swapping platform includes a tray, the tray including a first tray and a second tray, and the first mechanism and the second mechanism are respectively installed between the first tray and the second tray;

[0037] The first adjustment part is capable of driving the first tray to move; and / or, the second adjustment part is capable of driving the second tray to move.

[0038] In this solution, the above structure is adopted. The first adjustment part and the second adjustment part adjust the position of the unlocking mechanism by adjusting the tray. In this way, while adapting to the unlocking position of different battery pack models, the bearing area of ​​the tray can also be adjusted to improve stability.

[0039] Preferably, the lifting device can drive the battery swapping platform to perform a first lifting motion and a second lifting motion. The first lifting motion is used to realize the first half of the travel of the battery swapping platform during the assembly or disassembly of the battery pack, and the second lifting motion is used to realize the second half of the travel of the battery swapping platform during the assembly or disassembly of the battery pack. The adjusting device can drive the battery swapping platform to perform an adjusting motion, which is between the first lifting motion and the second lifting motion.

[0040] And / or,

[0041] The battery transport device includes a skid plate, which is a polyurethane gasket.

[0042] In this scheme, the above structure is adopted. During the installation and disassembly process of battery swapping, the lifting device first drives the battery pack to perform the first lifting motion. After moving a certain distance in the Z-axis direction, it ensures that the battery pack is out of contact with other structures. Then, it is aligned and adjusted by the adjustment motion. After the alignment and adjustment are completed, the second lifting motion is performed to complete the second half of the stroke. Finally, the installation and disassembly are completed and the battery pack is transported.

[0043] A battery swapping station includes a charging compartment and a battery swapping compartment, which includes the battery swapping equipment as described above, a battery swapping platform, an adjustment device and a lifting device disposed in the battery swapping compartment, and a battery transport device capable of shuttling between the charging compartment and the battery swapping compartment.

[0044] In this scheme, the above-described structure is adopted. The battery swapping equipment at the battery swapping station includes a battery transport device and a battery swapping platform. The transfer of battery packs takes place on the battery transport device, which only has the function of battery transfer and does not participate in the loading and unloading of battery packs. The loading and unloading function of battery packs is integrated into the battery swapping platform. The adjustment device can adjust the battery swapping platform to make fine adjustments for alignment or to adapt to different models of battery packs. By separating the transport and loading / unloading functions into two separate devices, the structures of each become simpler, and the number of mechanisms with repetitive functions is reduced, which helps to reduce the overall cost of the equipment.

[0045] Preferably, the charging compartment includes a first charging compartment and a second charging compartment, and the battery transport device is capable of shuttling between the first charging compartment and the battery swapping compartment.

[0046] In this solution, the aforementioned structure is adopted. The battery swapping station includes multiple battery compartments, each capable of holding battery packs of different specifications. Using this solution, only one swapping device is needed to swap batteries across multiple compartments. The battery transport device only performs battery transfer functions and does not participate in battery pack loading and unloading. Loading and unloading functions are integrated into the swapping platform. The battery transport device can move between different battery compartments to transport batteries of various specifications. The swapping platform is fixed at the swapping location for swapping and has XYZ directional adjustment devices. After functional decomposition, the individual structures become simpler, and the number of mechanisms with repetitive functions is reduced, helping to reduce the overall equipment cost and lower the failure rate.

[0047] The positive and progressive effects of this utility model are as follows: This utility model discloses a battery swapping device and a battery swapping station including the same. The battery swapping device includes a battery transport device for transfer and a battery swapping platform. The transfer of battery packs is carried out on the battery transport device, which only has the function of battery transfer and does not participate in the loading and unloading of battery packs. The loading and unloading function of battery packs is integrated into the battery swapping platform. The adjustment device can adjust the battery swapping platform to make fine adjustments for alignment or to adapt to different models of battery packs. After separating the transport and loading / unloading functions into two separate devices, the structure of each becomes simpler, and the number of mechanisms with repetitive functions is reduced, which helps to reduce the cost of the entire equipment.

[0080] Guide rail 101 Detailed Implementation

[0081] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0082] This embodiment first provides a battery swapping station, which is as follows: Figure 10As shown, the station includes a charging compartment and a battery swapping compartment 120. The charging compartment stores and charges the battery pack 5, while the battery swapping compartment 120 is used to replace the battery pack 5 for electric vehicles that have exited the battery swapping compartment 120. The battery swapping station is equipped with battery swapping equipment for transporting and replacing the battery pack 5. In this embodiment, the battery swapping station includes two battery compartments 110 to accommodate two different sizes of battery packs 5 for one or more electric vehicles. The battery swapping equipment can simultaneously install and remove the two types of battery packs 5 between the two battery compartments 110. In other embodiments, the number of battery compartments 110 may be only one or more.

[0083] The battery swapping equipment disclosed in this embodiment is as follows: Figure 1 As shown, it is used in, for example Figure 10 A battery swapping station for replacing battery packs 5 of electric vehicles includes a battery swapping platform 2, a battery transport device 1, an adjusting device 4, and a lifting device 3. The battery swapping platform 2 includes an unlocking mechanism for engaging and disengaging the locking mechanism of the battery pack 5. The battery transport device 1 can transport the battery pack 5 to or from the battery swapping platform 2. The adjusting device 4 can drive the battery swapping platform 2 and the unlocking mechanism in the X and Y axis directions. The lifting device 3 is used to drive the battery swapping platform 2 in the Z axis direction.

[0084] The battery swapping equipment includes a battery transport device 1 and a battery swapping platform 2 for transfer. The transfer of battery packs 5 takes place on the battery transport device 1, which only has the function of battery transfer and does not participate in the loading and unloading of battery packs 5. The loading and unloading function of battery packs 5 is integrated into the battery swapping platform 2. The adjustment device 4 can adjust the battery swapping platform 2 to make fine adjustments for alignment or to adapt to different models of battery packs 5. After separating the transport and loading / unloading functions into two separate devices, the structure of each becomes simpler, and the number of mechanisms with repetitive functions is reduced, which helps to reduce the cost of the entire equipment.

[0085] The adjustment mechanism is used for alignment. In this embodiment, the adjustment mechanism can adjust the position of the entire battery swapping platform 2 in both the X and Y axes to achieve alignment. In other embodiments, adjustment can be performed only in one direction, while the other direction is achieved using other mechanisms. Furthermore, the adjustment mechanism is only used to adjust the locking and unlocking mechanisms to achieve alignment without adjusting the entire battery swapping platform 2.

[0086] In this embodiment, as Figure 3 As shown, the battery transport device 1 is a shuttle vehicle that moves within the battery swapping station via its own walking mechanism 14 and guide rails 101 installed within the station. This battery transport device 1 can carry batteries on it and move them to the battery swapping platform 2 for swapping.

[0087] In other embodiments, the battery transport device 1 may not be equipped with a track but may use other conventional means such as wheels to achieve movement. In addition, multiple battery transport devices 1 may be set up to cooperate with a battery swapping platform 2, depending on the layout of the battery swapping station.

[0088] like Figure 3 As shown, the battery transport device 1 includes a vertical through-hole 11. When the battery swapping platform 2 loads or unloads the battery pack 5, the battery pack 5 and the battery swapping platform 2 are located on the upper and lower sides of the battery transport device 1, respectively. The battery swapping platform 2 unlocks or unlocks the battery pack 5 through the through-hole 11.

[0089] During battery swapping, the battery transport device 1 first moves to directly above the battery swapping platform 2, which is the first state. Figure 7 As shown. The battery swapping platform 2 can be lifted from below the battery transport device 1 to the height of the battery transport device 1 via the lifting device 3, and directly contact the battery transport device 1 through the port 11 to complete the unlocking / unlocking process. This is the second state, as shown. Figure 8 As shown. After alignment, the lifting device 3 can lift the battery swapping platform 2 and the battery pack 5 transport device together, which is the third state as shown. Figure 9 As shown. The entire process does not require any adjustment to the position of the battery pack 5. The battery swapping platform 2 directly operates the battery on the battery transport device 1, shortening the battery swapping process.

[0090] like Figure 2 , Figure 8 As shown, the battery swapping platform 2 can be driven to rise by the lifting device 3 and extend into the opening 11 to contact the battery pack 5 above the battery transport device 1. The battery transport device 1 has a frame structure with a hollow center for battery swapping. When the battery swapping equipment is swapping batteries, the battery swapping platform 2 extends into the battery transport device 1 and contacts the battery pack 5. The two are interlocked to form a whole to complete the loading and unloading of the battery pack 5, which is more convenient.

[0091] In this embodiment, during battery swapping, the tray of the battery swapping platform 2 directly contacts the battery transport device 1 through the port 11 and the battery pack 5.

[0092] In other embodiments, the battery swapping platform 2 may also be designed to pass through the battery transport device 1 and contact the battery pack 5 only through the unlocking mechanism, while other parts of the battery swapping platform 2 do not need to contact the battery pack 5, and the battery pack 5 is still carried by the battery transport device 1.

[0093] like Figures 2 to 4As shown, the battery swapping platform 2 includes a first positioning part 22, which is a recess located in the middle of the battery swapping platform 2. A corresponding second positioning part 12 is provided on the battery transport device 1, which is a limiting structure located in the center of the through hole of the battery transport device 1. The first positioning part 22 can align and engage with the second positioning part 12 when the battery swapping platform 2 rises. When the battery swapping platform 2 rises and extends into the through hole, the second positioning part 12 engages with the first positioning part 22. This structure allows the battery transport device 1 to be positioned with the battery swapping platform 2 during assembly operations, enabling them to be positioned relative to each other without additional position adjustments when transferring the battery pack 5, saving steps.

[0094] like Figure 2 , Figure 6 and Figure 8 As shown, the lifting device 3 can drive the battery swapping platform 2 and the battery transport device 1 to move synchronously in the Z-axis direction, and also drive the battery pack 5 to move synchronously in the Z-axis direction. The battery swapping platform 2 and the battery transport device 1 are aligned and connected to each other, rising and falling synchronously during battery swapping operations. The two form an integrated carrier for the battery pack 5, jointly realizing the loading and unloading of the battery pack 5. This avoids the cumbersome process of transferring the battery pack 5 from the battery transport device 1 to the battery swapping equipment and then having the battery swapping equipment carry the battery pack 5 for movement, and reduces the possibility of errors caused by the increased displacement of the battery pack 5 and the increased displacement of the battery pack 5.

[0095] The lifting device 3 has a scissor-shaped lifting arm, which can be lifted by common structures such as hydraulics or electric motors, and it supports the battery swapping platform 2.

[0096] like Figure 5 As shown, the battery swapping platform 2 includes a support frame 23. The support frame 23 is capable of contacting and supporting the battery transport device 1 and driving the battery transport device 1 to move synchronously when the battery swapping platform 2 rises. The support frame 23 is a horizontal bar that can contact the ground of the battery transport device 1 and lift it up when it rises. The state at this time is as follows... Figure 9 As shown, this is the third state. When the support frame 23 contacts the battery transport device 1, the upper surface of the battery swapping platform 2 is higher than the upper surface of the battery transport device 1. When the bottom surface of the battery transport device 1 contacts the support beam of the battery swapping platform 2, there is a certain step difference between the upper surface of the battery transport device 1 and the battery swapping platform 2. The purpose of this step difference is to ensure that the battery transport device 1 does not affect the unlocking process when the screw module is unlocked.

[0097] like Figure 5 , Figure 6As shown, the adjusting device 4 can drive the battery transport device 1 and the lifting device to move along the X and Y axes. The battery swapping platform 2 and the battery transport device 1 are aligned and connected to each other, rising and falling synchronously during battery swapping operations. They form an integrated battery pack 5 carrier, jointly realizing the loading and unloading of the battery pack 5. During loading and unloading, the adjusting device 4 can adjust both simultaneously, adjusting the positions of the battery swapping platform 2 and the battery transport device 1 during battery swapping so that the unlocking device can align with the locking structure of the battery pack 5. After battery swapping is completed, the position of the battery transport device 1 is adjusted to return it to the correct travel track.

[0098] The adjustment device 4 of the battery swapping equipment includes an X-axis adjustment section 41 and a Y-axis adjustment section 42, which can be mounted on either the battery swapping platform 2 or the lifting device 3. The X-axis adjustment section 41 can drive the battery swapping platform 2, or the lifting device 3 and the battery swapping platform 2 together, to move along the X-axis. The Y-axis adjustment section 42 can drive the battery swapping platform 2, or the lifting device 3 and the battery swapping platform 2 together, to move along the Y-axis. The adjustment device 4 is divided into an X-axis adjustment section 41, which enables X-axis position adjustment, and a Y-axis adjustment section 42, which enables Y-axis position adjustment. These two sections can respectively adjust the position of the battery swapping equipment or the unlocking / unlocking mechanism. They can be mounted in different positions to avoid structural conflicts. Furthermore, the two adjustment sections can be configured to drive the lifting device 3 to move the entire battery swapping equipment, or they can be configured to drive only the unlocking / unlocking mechanism to perform corresponding movements.

[0099] In this embodiment, as Figure 6 As shown, the X-axis adjustment section 41 is an adjustment platform, and the lifting device 3 is mounted on the adjustment platform and can move along the X-axis direction of the battery swapping platform 2 above it under the drive of the X-axis adjustment section 41. The Y-axis adjustment section 42 is as follows... Figure 5 As shown, the locking / unlocking device is mounted on the battery swapping platform 2 and drives the locking / unlocking mechanism to move along the Y-axis. The two movement modes are located in two different positions to minimize conflicts between their mechanisms. The X-axis adjustment unit 41 can drive the lifting device 3, allowing it to adjust the overall movement of the battery swapping platform 2. The Y-axis adjustment unit 42 only needs to adjust the position of the locking / unlocking mechanism, making it smaller and easier to integrate into the battery swapping platform 2.

[0100] In other embodiments, both can be mounted on the lifting device 3 or the battery swapping platform 2, or their installation positions can be reversed compared to this embodiment.

[0101] like Figure 4 , Figure 5As shown, the unlocking mechanism includes a first mechanism 211 and a second mechanism 212. The Y-axis adjustment part 42 includes a first adjustment part 421 capable of driving the first mechanism 211 to move and a second adjustment part 422 capable of driving the second mechanism 212 to move. The first adjustment part 421 can drive the first mechanism 211 to move closer to or further away from the second mechanism 212. The second adjustment part 422 can drive the second mechanism 212 to move closer to or further away from the first mechanism 211. The unlocking mechanism has two parts, and the Y-axis adjustment part 42 can adjust the relative positions of these two parts to accommodate more battery packs 5 of various specifications. In other embodiments, one of the first adjustment part 421 and the second adjustment part 422 can also be made movable, which can also achieve a certain degree of adjustment.

[0102] like Figure 5 As shown, the battery swapping platform 2 includes a tray, which comprises a first tray 221 and a second tray 222. A first mechanism 211 and a second mechanism 212 are respectively installed between the first tray 221 and the second tray 222. A first adjustment part 421 can drive the first tray 221 to move. A second adjustment part 422 can drive the second tray 222 to move. The first adjustment part 421 and the second adjustment part 422 adjust the position of the unlocking mechanism by adjusting the tray. In this way, while adapting to the unlocking position of different models of battery packs 5, the bearing area of ​​the tray can also be adjusted to improve stability.

[0103] In this embodiment, the X-axis adjustment part 41 and the Y-axis adjustment part 42 are motor-driven gear and rack structures. In other embodiments, other common drive structures may also be selected.

[0104] like Figure 3 As shown, the battery transport device 1 includes a skid plate 13, which is a polyurethane gasket.

[0105] During the battery swapping process, the lifting device 3 can drive the battery swapping platform 2 to perform a first lifting motion and a second lifting motion. The first lifting motion is used to realize the first half of the stroke of the battery swapping platform 2 when the battery pack 5 is assembled or disassembled. The second lifting motion is used to realize the second half of the stroke of the battery swapping platform 2 when the battery pack 5 is assembled or disassembled. The adjusting device 4 can drive the battery swapping platform 2 to perform an adjusting motion between the first lifting motion and the second lifting motion.

[0106] During the installation and dismantling of the battery swapping operation, the lifting device 3 first drives the battery pack 5 to perform the first lifting motion. After moving a certain distance in the Z-axis direction, it ensures that the battery pack 5 is out of contact with other structures. Then, it is aligned and adjusted by adjusting the movement. After the alignment and adjustment are completed, the second lifting motion is performed to complete the second half of the stroke, and finally, the installation, dismantling, and transfer are achieved.

[0107] Specifically:

[0108] 1. When installing the battery, the battery transport device 1 will first move to the battery swapping platform 2, so that the entire battery swapping equipment is in the first state. Figure 7 At this point, the lifting device 3 will perform the first lifting motion to raise the battery swapping platform 2 to lift the battery transport device 1 and the battery pack 5, and it will be in the third state. Figure 9 After lifting the battery pack 5 and battery transport device 1, the battery swapping equipment performs an adjustment movement. At this time, the X-axis adjustment unit 41 and the Y-axis adjustment unit 42 drive the battery swapping platform 2, battery transport device 1, and battery pack 5 to move together to align with the electric vehicle. After the adjustment movement is completed, a second lifting movement is performed to install the battery pack 5 onto the electric vehicle.

[0109] 2. During battery removal, the battery swapping platform 2 first detaches the battery transport device 1 and the battery pack 5 from the electric vehicle. After removing the battery pack 5 from the electric vehicle, the battery swapping equipment undergoes an adjustment movement. At this time, the X-axis adjustment unit 41 and the Y-axis adjustment unit 42 drive the battery swapping platform 2, the battery transport device 1, and the battery pack 5 to move together to align with the track. After the adjustment movement is completed, a second lifting movement is performed to install the battery transport device 1 onto the track.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
