Description

Technical Field

[0001] This invention relates to the field of battery swapping technology for electric vehicles, and particularly to a battery swapping platform and battery swapping equipment including the same. Background Technology

[0002] Currently, in the fast-swapping technology of new energy vehicles, the batteries are fixed to the vehicle chassis. Therefore, when replacing the battery pack, specialized battery swapping equipment needs to be moved to the bottom of the vehicle for battery removal or installation. Since the space under electric vehicles is very limited, and the battery itself has a certain thickness, the height of the battery swapping platform affects the swapping operation space and the capacity of the battery that can be installed. Generally, the larger the battery capacity, the larger its volume.

[0003] In existing technologies, the height of battery swapping platforms is too high, which limits the space for battery swapping operations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that the battery swapping platform is too high in the existing battery swapping technology for electric vehicles, which restricts the battery swapping operation space, and to provide a battery swapping platform and battery swapping equipment including the same.

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

[0006] A battery swapping platform includes a base plate and a battery positioning component and a vehicle body positioning component disposed on the base plate. The battery positioning component is used to drive the battery to move horizontally, and the vehicle body positioning component is used to move horizontally to determine the position of the battery swapping platform relative to the vehicle body. The projections of the battery positioning component and the vehicle body positioning component on the base plate do not overlap.

[0007] In this solution, the battery swapping platform, through the above-mentioned configuration, allows two horizontally moving positioning components (battery positioning component and vehicle body positioning component) to be arranged on the same horizontal plane, eliminating the need for a height difference arrangement. This reduces the overall height of the battery swapping platform and increases the operating space for battery swapping.

[0008] Preferably, the battery positioning assembly includes a battery positioning plate having a receiving space and a battery positioning actuator for driving the battery positioning plate to move, and the vehicle positioning assembly includes a vehicle positioning plate having a receiving space extending into the battery positioning plate and a vehicle positioning actuator placed in the receiving space and for driving the vehicle positioning plate to move.

[0009] In this solution, the vehicle positioning plate is extended to the accommodating space included in the battery positioning plate, and the vehicle positioning driver is placed in the accommodating space, forming an interlaced and non-overlapping arrangement between the battery positioning plate and the vehicle positioning plate on the horizontal plane. The components of the battery positioning assembly and the vehicle positioning assembly are distributed, making the layout on the horizontal plane more compact and making it easier to reduce the overall height of the battery swapping platform.

[0010] Preferably, the battery positioning assembly includes two battery positioning plates that are spaced apart from each other and independent of each other, and the area between the two battery positioning plates or the outer edge area forms the receiving space; the two battery positioning plates are driven and connected by independent battery positioning drivers.

[0011] In this design, the battery positioning assembly uses two spaced-apart, independent battery positioning plates instead of a single, integral plate, which simplifies manufacturing. Each of the two positioning plates is driven by an independent battery positioning driver, allowing for a smaller driver and reducing its overall height. Furthermore, when the components supported by the battery positioning plate are heavy and require two drivers, the independent drivers prevent damage caused by inconsistent movement when two drivers simultaneously operate on the same plate, effectively protecting the drivers' normal operation. By creating a accommodating space between the two positioning plates and at their outer edges—space that can accommodate the extension of the vehicle body positioning plate to the battery positioning plate, the vehicle body positioning driver, and other components—the design further increases the space available for the battery positioning assembly and the vehicle body positioning assembly to be arranged in an interleaved manner, optimizing the layout and thus contributing to a reduction in the overall height of the battery swapping platform.

[0012] Preferably, the vehicle positioning plate includes a first protrusion extending into a receiving space between the two battery positioning plates, and the vehicle positioning actuator is disposed between the two battery positioning plates and connected to the bottom surface of the first protrusion.

[0013] In this design, the first protrusion of the vehicle positioning plate and the vehicle positioning driver are placed and connected within the receiving space between the two battery positioning plates. This effectively utilizes the space between the two independent battery positioning plates, optimizes the layout, and helps reduce the overall height of the battery swapping platform. The connection point between the vehicle positioning driver and the first protrusion is located on the bottom surface of the first protrusion, rather than the top surface. This ensures that the vehicle positioning plate and the battery positioning plate do not overlap along their projections, while the vehicle positioning plate can be slightly higher than the battery positioning plate. This allows for more horizontal movement space when the first protrusion moves without interfering with the battery positioning plate. In other words, the vehicle positioning plate does not need to increase its spacing to avoid interference with the battery positioning plate when the first protrusion moves. Therefore, the battery swapping platform does not need to be very large in the direction of movement of the battery positioning plate.

[0014] Preferably, the vehicle positioning driver and the battery positioning plate at least partially overlap in the height direction.

[0015] In this solution, the space occupied by the vehicle positioning drive in the vertical direction is reduced by the above settings, which helps to reduce the overall height of the battery swapping platform.

[0016] Preferably, the battery positioning plate has a receiving groove, the battery positioning driver is disposed in the receiving groove and is connected from above to the top surface of the battery positioning plate via a connector.

[0017] In this design, the battery positioning driver is housed in a recessed slot on the battery positioning plate, reducing the space occupied by the battery positioning driver in the vertical direction and thus lowering the overall height of the battery swapping platform. Connecting the battery positioning driver to the top surface of the battery positioning plate from above eliminates the need for the connection structure between the two (battery positioning driver and battery positioning plate) to occupy the space below the battery positioning plate. Instead, it utilizes the existing space above the battery positioning plate (the existing space for supporting the battery), further reducing the overall height of the battery positioning assembly.

[0018] Preferably, the battery positioning assembly further includes a battery positioning guide mechanism that is guided by both sides of each battery positioning plate. The battery positioning guide mechanism includes at least two guide rails disposed on the substrate and a plurality of first sliders disposed on the bottom surface of the battery positioning plate and slidingly engaged with the guide rails.

[0019] In this design, the sliding engagement of the guide rail and the first slider enables the movement and guidance of the battery positioning plate. The battery positioning guide mechanism is positioned on both sides of the battery positioning plate, staggered from the component located between the two battery positioning plates, thus optimizing the layout on the horizontal plane.

[0020] Preferably, the outer edge of each battery positioning plate near the end of the vehicle body positioning plate is recessed inward to form a clearance area as the receiving space, and the guide rail of the battery positioning guide mechanism located at the outer edge of each battery positioning plate serves as a common guide rail, which extends through the clearance area to the bottom of the vehicle body positioning plate.

[0021] The vehicle positioning plate includes a second protrusion extending toward the avoidance area. The vehicle positioning assembly also includes a vehicle positioning guide mechanism. The vehicle positioning guide mechanism includes a second slider disposed on the bottom surface of the second protrusion. The second slider is slidably connected to the common guide rail.

[0022] In this design, the avoidance zone and the second protrusion at the aforementioned locations cooperate to form an interlaced arrangement structure, ensuring that the outer edge of the battery positioning plate does not overlap with the vehicle body positioning plate along the projection direction. A common guide rail is positioned at the outer edge of the battery positioning plate to connect the battery positioning plate and the vehicle body positioning plate, without occupying the space inside the battery positioning plate or between the two battery positioning plates. This optimizes the horizontal layout and achieves consistent guidance between the battery positioning assembly and the vehicle body positioning assembly through the common guide rail, improving guidance accuracy and precision. Specifically, the sliding engagement of the second slider with the common guide rail enables the movement and guidance of the vehicle body positioning plate.

[0023] Preferably, the battery swapping platform further includes a tray assembly that is floatingly connected above the battery positioning assembly. The tray assembly is used to carry the battery. The tray assembly is connected to the battery positioning plate through a plurality of spring floating members disposed on the battery positioning plate. The plurality of spring floating members are evenly disposed in the outer edge area of ​​the two battery positioning plates.

[0024] In this design, the tray assembly is connected to the battery positioning plate via spring-loaded floating components, facilitating battery position adjustment during battery swapping. Multiple spring-loaded floating components are evenly distributed along the outer edges of the two battery positioning plates, making it easier to inspect the drive located in the central area of ​​the tray assembly.

[0025] Preferably, each of the battery positioning plates has a snap-fit ​​groove on the plate body located in front of the battery positioning driver along its direction of movement, the snap-fit ​​groove being used to engage with a snap-fit ​​plate on the bottom surface of the tray assembly.

[0026] In this solution, the battery positioning plate and the tray assembly are detachably connected by the snap-fit ​​groove and snap-fit ​​plate as described above. The snap-fit ​​structure is a rigid connection, which, in conjunction with the floating connection achieved by the spring floating component, enables the floating adjustment and locking of the battery position.

[0027] Preferably, the tray assembly includes two horizontal plates arranged along the moving direction of the battery positioning assembly, and the two horizontal plates are fixedly connected to each other by a plurality of vertical plates; the horizontal plates are embedded in the spring floating member one by one by a plurality of protrusions; the battery positioning driver and the vehicle positioning driver are arranged to avoid the plurality of vertical plates.

[0028] In this design, the horizontal and vertical plates position the tray and battery positioning plate from two directions. The horizontal plate uses multiple protrusions embedded in the spring-loaded floating components to achieve a floating connection between the tray assembly and the battery positioning plate. This allows the carried battery to be repositioned as needed, facilitating guidance during battery removal and installation. The battery positioning actuator and the vehicle body positioning actuator are designed to avoid conflict with the multiple vertical plates, facilitating maintenance by avoiding their installation locations. Furthermore, the battery positioning actuator and the vehicle body positioning actuator do not occupy additional space in the height direction, thus reducing the overall height of the battery swapping platform.

[0029] Preferably, an unlocking device and a vision sensor are installed on the lower surface of the cross plate. The unlocking device cooperates with the locking mechanism of the battery under the vehicle to unlock or lock the battery. The vision sensor is used to detect whether the locking mechanism of the battery under the vehicle is locked in place. The unlocking device and the vision sensor are located in the receiving space of the outer edge area of ​​the two battery positioning plates.

[0030] In this solution, the space at the outer edge of the battery positioning plate is fully utilized to house the unlocking device and the vision sensor. The unlocking device and the vision sensor overlap with the battery positioning plate in the height direction, which helps to reduce the height of the tray assembly and thus the overall height of the battery swapping platform.

[0031] A battery swapping device, the battery swapping device comprising the battery swapping platform as described above.

[0032] In this solution, by adopting the aforementioned battery swapping platform, the overall height of the battery swapping equipment is reduced, the operating space for battery swapping is increased, and the battery capacity that the battery swapping equipment can carry is improved.

[0033] The positive and progressive effects of the present invention are as follows: the battery swapping platform and the battery swapping equipment therein adopt a design in which the projections of the battery positioning component and the vehicle positioning component on the base plate do not overlap, so that the two horizontally moving positioning components can be arranged on the same horizontal plane without the need for an arrangement with a height difference, thereby reducing the overall height of the battery swapping platform and increasing the operating space for battery swapping.

[0071] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0072] Example 1

[0073] like Figure 1-5 As shown, this embodiment provides a battery swapping platform 1, installed on a battery swapping trolley, to provide a platform for replacing the battery of an electric vehicle from the bottom. During battery swapping, the battery swapping trolley moves to the bottom of the vehicle, removes the depleted battery from the bottom of the vehicle, and places it on the battery swapping platform 1; or the battery swapping platform 1 is raised, and a fully charged battery placed on it is installed on the bottom of the vehicle.

[0074] The battery swapping platform 1 includes a base plate 2 and a battery positioning component 3 and a vehicle positioning component 4 disposed on the base plate 2. The battery positioning component 3 is used to drive the battery to move horizontally, and the vehicle positioning component 4 is used to move horizontally to determine the position of the battery swapping platform 1 relative to the vehicle body. The projections of the battery positioning component 3 and the vehicle positioning component 4 on the base plate 2 do not overlap.

[0075] The battery swapping platform 1 adopts a design that allows the two horizontally moving positioning components (battery positioning component 3 and vehicle positioning component 4) to be arranged on the same horizontal plane without the need for a height difference arrangement, thereby reducing the overall height of the battery swapping platform 1 and increasing the operating space for battery swapping.

[0076] Among them, such as Figure 2As shown, the battery positioning assembly 3 includes a battery positioning plate 31 with a receiving space 310 and a battery positioning actuator 32 for driving the battery positioning plate 31 to move. The vehicle body positioning assembly 4 includes a vehicle body positioning plate 41 with a receiving space 310 extending into the battery positioning plate 31 and a vehicle body positioning actuator 42 placed within the receiving space 310 and used to drive the vehicle body positioning plate 41 to move. In this embodiment, the battery positioning actuator 32 and the vehicle body positioning actuator 42 are specifically two drive motors.

[0077] The battery swapping platform 1 extends the vehicle positioning plate 41 to the accommodating space 310 included in the battery positioning plate 31, and places the vehicle positioning driver 42 in the accommodating space 310, forming an interlaced and non-overlapping arrangement between the battery positioning plate 31 and the vehicle positioning plate 41 on the horizontal plane. The components of the battery positioning assembly 3 and the vehicle positioning assembly 4 are distributed, making the layout on the horizontal plane more compact and making it easier to reduce the overall height of the battery swapping platform 1.

[0078] There are many structural forms that can achieve the non-overlapping projections of the battery positioning component 3 and the vehicle positioning component 4 on the substrate 2. In other embodiments, depending on the specific arrangement of each component on the battery swapping platform 1, the battery positioning plate 31 and the vehicle positioning plate 41 can have different shapes and structures, and are not limited to the structural forms of this embodiment.

[0079] The battery positioning assembly 3 includes two battery positioning plates 31 that are spaced apart and independent of each other. The area 311 or the outer edge area 312 between the two battery positioning plates 31 forms a receiving space 310; that is, the receiving space 310 includes two areas: one is the middle area 311 between the two battery positioning plates 31, and the other is the outer edge area 312 located on the two battery positioning plates 31. The two battery positioning plates 31 are driven and connected by independent battery positioning drivers 32.

[0080] The battery positioning assembly 3 uses two spaced-apart, independent battery positioning plates 31, instead of a single integral battery positioning plate 31, which facilitates manufacturing. Each of the two battery positioning plates 31 is driven by an independent battery positioning driver 32, allowing the battery positioning driver 32 to be smaller, thus reducing its height. Furthermore, smaller drive motors are less expensive and easier to procure. Moreover, when the components supported by the battery positioning plate 31 are heavy and require two battery positioning drivers 32, the independent drive connection between the two battery positioning plates 31 avoids the possibility of inconsistent movement that could damage the drivers if two drivers simultaneously drive the same battery positioning plate, effectively protecting the drivers for normal operation. By forming a receiving space 310 in the area between the two battery positioning plates 31 and the outer edge area, which can be used to accommodate the part of the vehicle positioning plate 41 extending to the battery positioning plate 31 (i.e. the first protrusion 411), the vehicle positioning driver 42 and other components, the space for the battery positioning assembly 3 and the vehicle positioning assembly 4 to be arranged in an interlaced manner is further improved, the layout is optimized, and thus it is beneficial to reduce the overall height of the battery swapping platform 1.

[0081] Provided that the projections of the battery positioning plate 31 and the vehicle positioning plate 41 on the substrate 2 do not overlap, the battery positioning plate 31 and the vehicle positioning plate 41 can have different shapes and structural forms according to the structural fit requirements. For example, in other embodiments, the battery positioning plate 31 can also be a single plate, with a receiving space 310 carved out at the middle position and outer edge of the single plate to accommodate the vehicle positioning actuator 42 or other components; or the battery positioning plate 31 can also be divided into more plates. Similarly, the vehicle positioning plate 41 can be a single plate in this embodiment, or it can be two separate plates.

[0082] The vehicle positioning plate 41 includes a first protrusion 411 extending into the receiving space 310 between the two battery positioning plates 31, and the vehicle positioning driver 42 is disposed between the two battery positioning plates 31 and connected to the bottom surface of the first protrusion 411.

[0083] In other embodiments, the vehicle positioning plate 41 may also omit the first protrusion 411, and instead extend the output end of the vehicle positioning driver 42 to other areas outside the accommodating space 310 and connect it to the vehicle positioning plate 41. However, this structure is not as effective as the battery swapping platform 1 of this embodiment, which places the first protrusion 411 of the vehicle positioning plate 41 and the vehicle positioning driver 42 in the accommodating space 310 between the two battery positioning plates 31 and connects them, thus effectively utilizing the space between the two independent battery positioning plates 31, optimizing the layout, and helping to reduce the overall height of the battery swapping platform 1. The connection position between the vehicle positioning driver 42 and the first protrusion 411 is set on the bottom surface of the first protrusion 411, rather than on the top surface. This allows the vehicle positioning plate 41 and the battery positioning plate 31 to not overlap along the projection, while the vehicle positioning plate 41 can be slightly higher than the battery positioning plate 31. As a result, when the first protrusion 411 moves, there is more horizontal movement space without interfering with the battery positioning plate 31. That is, the vehicle positioning plate 41 does not need to increase the distance to avoid interference with the battery positioning plate 31 when the first protrusion 411 moves. In this way, the battery swapping platform 1 does not need to be made very large in the direction of movement of the battery positioning plate 31 (i.e., the direction of movement A of the battery positioning assembly).

[0084] In this embodiment, the vehicle positioning component 4 includes two vehicle positioning actuators 42, which are arranged side by side and positioned between the two battery positioning plates 31. Using two vehicle positioning actuators 42, instead of a single large one, allows for smaller vehicle positioning actuators 42, reducing their overall height. Similar to the two smaller battery positioning actuators 32, the vehicle positioning actuators 42 utilize smaller drive motors, which are less expensive and easier to procure.

[0085] In this embodiment, the vehicle positioning driver 42 and the battery positioning plate 31 at least partially overlap in the height direction. Specifically, in this embodiment, the vehicle positioning driver 42 is mostly placed within the receiving space 310 between the two battery positioning plates 31, achieving partial overlap in the height direction. In other embodiments, depending on the structure, the vehicle positioning driver 42 and the battery positioning plate 31 may partially overlap or completely overlap in the height direction. This arrangement reduces the space occupied by the vehicle positioning driver 42 in the height direction, which helps to reduce the overall height of the battery swapping platform 1.

[0086] The battery positioning plate 31 has a receiving groove 314, and the battery positioning driver 32 is disposed in the receiving groove 314 and connected to the top surface of the battery positioning plate 31 from above by a connector 33. In this embodiment, the connector 33 is a block, with both ends of the block spanning the receiving groove 314 and connected to the top surface of the battery positioning plate 31.

[0087] By placing the battery positioning driver 32 in the receiving slot 314 opened on the battery positioning plate 31, the space occupied by the battery positioning driver 32 in the height direction is reduced, which helps to reduce the overall height of the battery swapping platform 1. By connecting the battery positioning driver 32 to the top surface of the battery positioning plate 31 from above, the connection structure between the two (battery positioning driver 32 and battery positioning plate 31) does not occupy the space below the battery positioning plate 31, but utilizes the existing space above the battery positioning plate 31 (the existing space for carrying the battery), thus reducing the overall height of the battery positioning assembly 3.

[0088] The battery positioning assembly 3 further includes battery positioning guide mechanisms 34 that are respectively guided from both sides of each battery positioning plate 31. Each battery positioning guide mechanism 34 includes at least two guide rails 341 disposed on the base plate 2 and a plurality of first sliders 342 disposed on the bottom surface of the battery positioning plate 31 and slidingly engaged with the guide rails 341. The sliding engagement of the guide rails 341 and the first sliders 342 enables the movement and guidance of the battery positioning plate 31. By placing the battery positioning guide mechanisms 34 on both sides of the battery positioning plate 31 and staggering them from components located between the two battery positioning plates 31, the layout on the horizontal plane is optimized.

[0089] like Figure 2 As shown, the outer edge of each battery positioning plate 31 near the vehicle body positioning plate 41 is recessed inward to form a clearance area 313 serving as a receiving space 310. The guide rail 341 of the battery positioning guide mechanism 34 located on the outer edge of each battery positioning plate 31 serves as a common guide rail 341, which extends through the clearance area 313 to the underside of the vehicle body positioning plate 41. Each of the two battery positioning plates 31 has a battery positioning guide mechanism 34 on its outer edge, thus there are two common guide rails 341 on the left and right sides. The vehicle body positioning plate 41 includes a second protrusion 412 extending toward the clearance area 313. The vehicle body positioning assembly 4 also includes a vehicle body positioning guide mechanism 43, which includes a second slider 44 disposed on the bottom surface of the second protrusion 412. The second slider 44 is slidably connected to the common guide rail 341.

[0090] In this structure, the avoidance area 313 and the second protrusion 412 cooperate to form an interlaced arrangement, ensuring that the outer edge of the battery positioning plate 31 does not overlap with the vehicle body positioning plate 41 along the projection direction. A common guide rail 341 is positioned at the outer edge of the battery positioning plate 31 to connect the battery positioning plate 31 and the vehicle body positioning plate 41, without occupying the space inside the battery positioning plate 31 or between the two battery positioning plates 31. This optimizes the layout on the horizontal plane and achieves consistent guidance between the battery positioning assembly 3 and the vehicle body positioning assembly 4 through the common guide rail 341, improving guidance accuracy and precision. The sliding engagement of the second slider 44 with the common guide rail 341 enables the movement and guidance of the vehicle body positioning plate 41.

[0091] Among them, such as Figure 1 and Figure 4 , Figure 5 As shown, the battery swapping platform 1 also includes a tray assembly 5 that is floatingly connected above the battery positioning assembly 3. The tray assembly 5 is used to carry the battery. The tray assembly 5 is connected to the battery positioning plate 31 through a plurality of spring floating members 35 provided on the battery positioning plate 31. The plurality of spring floating members 35 are evenly provided in the outer edge area of ​​the two battery positioning plates 31.

[0092] The tray assembly 5 is connected to the battery positioning plate 31 via spring-loaded floating elements 35, facilitating battery position adjustment during battery swapping. Multiple spring-loaded floating elements 35 are evenly distributed along the outer edge areas of the two battery positioning plates 31, facilitating maintenance of the driver located in the central area of ​​the tray assembly 5.

[0093] like Figure 2 , Figure 5 As shown, each battery positioning plate 31 has a snap-fit ​​groove 36 on its plate body located in front of the battery positioning driver 32 along its moving direction (i.e., the moving direction A of the battery positioning assembly). The snap-fit ​​groove 36 is used to cooperate with the snap-fit ​​plate 53 on the bottom surface of the tray assembly 5. Through the connection and cooperation of the snap-fit ​​groove 36 and the snap-fit ​​plate 53, the battery positioning plate 31 and the tray assembly 5 are detachably connected. Moreover, this snap-fit ​​structure is a rigid connection, which cooperates with the floating connection achieved by the spring floating member 35 to realize the floating adjustment and locking position of the battery.

[0094] like Figure 4 and Figure 5 As shown, the tray assembly 5 includes two horizontal plates 51 arranged along the moving direction of the battery positioning assembly 3 (i.e., the moving direction A of the battery positioning assembly). The two horizontal plates 51 are fixedly connected to each other by multiple vertical plates 52. The horizontal plates 51 are embedded in the spring floating member 35 one-to-one by multiple protrusions 54. The battery positioning driver 32 and the vehicle positioning driver 42 are arranged to avoid the multiple vertical plates 52. In this structure, the horizontal plates 51 and the vertical plates 52 position the tray and the battery positioning plate 31 from two directions respectively. The horizontal plates 51 are embedded in the spring floating member 35 one-to-one by multiple protrusions 54 to realize the floating connection between the tray assembly 5 and the battery positioning plate 31, so that the battery can be adjusted in position as needed, which facilitates guidance when removing and installing the battery. The battery positioning driver 32 and the vehicle positioning driver 42 are arranged to avoid the installation positions of the multiple longitudinal plates 52, which facilitates maintenance; at the same time, the battery positioning driver 32 and the vehicle positioning driver 42 do not occupy extra space in the height direction, which helps to reduce the overall height of the battery swapping platform 1.

[0095] like Figure 5 As shown, an unlocking device 55 and a vision sensor 56 are installed on the lower surface of the horizontal plate 51. The unlocking device 55 is used to cooperate with the locking mechanism of the battery under the vehicle to unlock or lock the battery. The vision sensor 56 is used to detect whether the locking mechanism of the battery under the vehicle is locked in place. The unlocking device 55 and the vision sensor 56 are located in the receiving space 310 of the outer edge area of ​​the two battery positioning plates 31.

[0096] The battery swapping platform 1 makes full use of the accommodating space 310 of the outer edge area of ​​the battery positioning plate 31 to house the unlocking device 55 and the vision sensor 56. The unlocking device 55 and the vision sensor 56 overlap with the battery positioning plate 31 in the height direction, which helps to reduce the height of the tray assembly 5, and thus helps to reduce the overall height of the battery swapping platform 1.
