Description

Technical Field

[0001] This application relates to the field of battery swapping technology for new energy electric vehicles, and in particular to a power battery storage rack suitable for battery swapping stations for new energy electric vehicles. Background Technology

[0002] Currently, new energy electric vehicles are experiencing explosive growth, with some functional electric vehicles developing rapidly and facing enormous social demand. For example, intensive charging and battery swapping stations for new energy electric buses and sanitation vehicles are convenient for large-scale application due to their timed, location-based, and route-based characteristics, clear ownership, and ease of use. Therefore, it is foreseeable that battery swapping has significant potential for large-scale and networked development in my country's future new energy electric vehicle development. Battery swapping is also in a rapid development phase, serving as a crucial energy replenishment method for new energy vehicles. Battery swapping is mainly divided into centralized charging and charging / swapping modes. As a highly efficient energy replenishment method, its development will help promote the growth in demand for new energy vehicles.

[0003] Battery swapping stations are energy stations that provide charging and rapid battery swapping for electric vehicles. New energy electric vehicles need to have their batteries swapped through dedicated battery swapping stations.

[0004] To reduce their footprint, most battery swapping stations use stacked storage for power batteries, which limits the space available for them. This means that when drivers need to retrieve batteries from under the battery storage rack, they have to use external tools to move them. Sometimes, the batteries are too heavy to be safely retrieved, resulting in a poor user experience for new energy electric vehicles during battery swapping. Summary of the Invention

[0005] Therefore, it is necessary to provide a power battery storage rack suitable for new energy electric vehicle battery swapping stations that reduces the difficulty of retrieving batteries from under the battery storage rack, addressing the issues that car owners need to use external tools to move the power battery when retrieving it from under the battery storage rack, or even that the battery is too heavy to be safely retrieved.

[0006] A power battery storage rack suitable for battery swapping stations for new energy electric vehicles, comprising:

[0007] The housing has an inner cavity for accommodating the power battery; the bottom side of the housing is provided with an inlet and outlet communicating with the inner cavity;

[0008] A platform is disposed below the inlet and outlet; the platform is spaced apart from the inlet and outlet, and a pick-and-place station is formed between the platform and the inlet and outlet;

[0009] A push plate is slidably disposed relative to the platform in a horizontal direction; the sliding path of the push plate extends at least partially to the pick-and-place station; the sliding path of the push plate also extends at least partially to one side of the pick-and-place station; and

[0010] A push drive is connected to the push plate and forms a transmission engagement with the push plate that enables the push plate to slide relative to the platform.

[0011] The aforementioned battery storage rack for new energy electric vehicle battery swapping stations operates as follows: When a battery with insufficient charge needs recharging, the user first places the battery horizontally into the pick-and-place station from the other side. Before this, a pusher plate slides to one side of the pick-and-place station, thus not affecting the battery's entry. A platform supports the battery in the pick-and-place station. Subsequently, the battery rises from the platform and enters the inner cavity of the housing via the inlet / outlet. When the battery is housed within the inner cavity, its electrodes are electrically connected to the output of the charging power supply, and the battery enters a charging state. After the battery is charged to the required capacity, it descends from the inlet / outlet onto the platform. Then, a pusher drive moves the pusher plate, which pushes the battery from one side of the pick-and-place station to the other side relative to the platform, pushing it away from the other side of the station. When the user or new energy vehicle is on the other side of the battery swapping station, this design avoids the need for the user to reach through a narrow space and around to the back of the battery to pull it, or to use external tools to move the battery. The pushing force of the push plate reduces the force required by the user during battery removal, which is beneficial for safe battery removal and improves the user experience of new energy electric vehicles during battery swapping operations.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0037] This application provides a battery swapping station.

[0038] In some implementations, the battery swapping station can accommodate new energy vehicles. Furthermore, the station can charge the power batteries removed from the new energy vehicles. The station can also supply fully charged power batteries to the new energy vehicles. Specifically, the power batteries can be used to power the drive motors of the new energy vehicles.

[0039] In some implementations, combined Figure 1 As shown, the battery swapping station is equipped with a power battery storage rack 100 suitable for new energy electric vehicle battery swapping. The power battery storage rack 100 provides storage space for the power battery and inputs charging current to it. Furthermore, the power battery storage rack 100 is installed on the ground. Multiple power battery storage racks 100 are provided, spaced apart from adjacent racks to allow new energy vehicles to pass through and to allow them to unload the power battery near the rack, thus reducing the distance the power battery travels after being removed from the vehicle.

[0040] In some embodiments, the battery swapping station includes a control system for controlling the permissible modes of the power battery storage rack 100 suitable for the new energy electric vehicle battery swapping station and for monitoring the operation of the power battery storage rack 100 suitable for the new energy electric vehicle battery swapping station.

[0041] Combination Figures 1 to 8 As shown, this application also provides a power battery storage rack 100 suitable for battery swapping stations for new energy electric vehicles.

[0042] In some implementations, combined Figure 1 and Figure 2 As shown, a power battery storage rack 100 suitable for a new energy electric vehicle battery swapping station includes: a housing 20, a platform 30, a pusher plate 40, and a pushing drive component 50. The housing 20 has an inner cavity for accommodating the power battery. An inlet / outlet communicating with the inner cavity is provided on the bottom side of the housing 20. The platform 30 is disposed below the inlet / outlet. The platform 30 is spaced apart from the inlet / outlet, and a pick-and-place station 31 is formed between the platform 30 and the inlet / outlet. The pusher plate 40 is slidably disposed relative to the platform 30 in a horizontal direction. The sliding path of the pusher plate 40 extends at least partially to the pick-and-place station 31. The sliding path of the pusher plate 40 also extends at least partially to one side of the pick-and-place station 31. The pushing drive component 50 is connected to the pusher plate 40 and forms a transmission engagement with the pusher plate 40 that allows the pusher plate 40 to slide relative to the platform 30.

[0043] Specifically, when a low-powered battery needs charging, the user first places the battery horizontally into the pick-up and place station 31 from the other side. Before this, the push plate 40 slides to one side of the pick-up and place station 31, thus not affecting the battery's entry into the station. The platform 30 supports the battery in the pick-up and place station 31. Then, the battery rises away from the platform 30 and enters the inner cavity of the housing 20 through the inlet and outlet. When the battery is housed in the inner cavity of the housing 20, its electrodes are electrically connected to the output of the charging power supply, and the battery enters the charging state. After the battery is charged to the required capacity, it descends from the inlet and outlet onto the platform 30. Subsequently, the pusher 50 drives the pusher plate 40 to move. As the pusher plate 40 slides along one side of the pick-up and drop-off station 31 towards the other side relative to the platform 30, it pushes the power battery, causing it to leave the other side of the pick-up and drop-off station 31. When the user or new energy vehicle is on the other side of the pick-up and drop-off station 31, this avoids the need for the user to reach through a narrow space and around to the back of the power battery to pull it, or the need to use external tools to move the power battery. The pushing force of the pusher plate 40 reduces the force required by the user during the removal of the power battery, which is beneficial for safe removal and improves the user experience of new energy electric vehicles during battery swapping operations.

[0044] In some embodiments, the power battery storage rack 100 suitable for new energy electric vehicle battery swapping stations includes a lifting and traction device for moving the power battery up and down. In one embodiment, the lifting and traction device is used to lift the power battery from the pick-and-place station 31 into the inner cavity of the housing 20. In another embodiment, the lifting and traction device is used to lower the power battery from the inner cavity of the housing 20 onto the platform 30.

[0045] In some embodiments, after the push plate 40 pushes the power battery out of the pick-and-place station 31, the push drive 50 drives the push plate 40 to move, and the push plate 40 resets along the other side of the pick-and-place station 31 to one side of the pick-and-place station 31 and leaves the pick-and-place station 31, so that the power battery can be put into the pick-and-place station 31 from the other side of the pick-and-place station 31, or so that the power battery in the housing 20 can continue to descend to the platform 30.

[0046] In some implementations, combined Figure 2 As shown, the sliding path of the push plate 40 is parallel to arrow F1.

[0047] In some implementations, multiple power batteries are stacked from top to bottom within the cavity.

[0048] In some implementations, combined Figures 2 to 4 As shown, the system also includes a substrate 21 and a slider 22. The substrate 21 is fixedly disposed relative to the stage 30 in a horizontal direction. The slider 22 is slidably inserted into the substrate 21. A push plate 40 is connected to the slider 22. A threaded transmission relationship is formed between the output shaft 51 of the push drive 50 and the slider 22. Specifically, since the substrate 21 is fixedly disposed relative to the stage 30 in a horizontal direction, when the slider 22 slides horizontally relative to the substrate 21, the push plate 40 can slide horizontally relative to the stage 30. When a threaded transmission relationship is formed between the output shaft 51 of the push drive 50 and the slider 22, when the output shaft 51 of the push drive 50 rotates circumferentially, the slider 22 can slide horizontally relative to the substrate 21 due to the threaded relationship, thereby driving the push plate 40 to slide relative to the stage 30.

[0049] In some implementations, combined Figure 4 and Figure 8 As shown, the substrate 21 has an inner groove 211 and an outer groove 212, with the outer groove 212 located between the outer surface of the substrate 21 and the inner groove 211. The width of the inner groove 211 is greater than the width of the outer groove 212. The slider 22 has an inner strip portion 221 and an outer strip portion 222 connected to the inner strip portion 221. The inner strip portion 221 is movably disposed in the outer groove 212, and the outer strip portion 222 is movably disposed in the inner groove 211. The width of the outer strip portion 222 is greater than the width of the inner strip portion 221. Specifically, in conjunction with... Figure 8As shown, the slider 22 also includes a slide cylinder 223, which forms a threaded transmission relationship with the output shaft 51 of the push drive 50. An inner strip 221 is connected between the slide cylinder 223 and the outer strip 222. Further, the slide cylinder 223, the inner strip 221, and the outer strip 222 are arranged parallel to each other in their length directions. The width of the outer groove 212 is greater than the width of the inner strip 221 and less than the width of the outer strip 222, thereby confining the outer strip 222 within the inner groove 211, maintaining a sliding fit between the slider 22 and the substrate 21. In one embodiment, combined with... Figure 8 As shown, the cross-sections of the inner strip 221 and the outer strip 222 are T-shaped.

[0050] In some implementations, combined Figure 2 and Figure 6 As shown, the side of the pusher plate 40 used to push the power battery is covered with a flexible layer 23 to prevent the pusher plate 40 from scratching the surface of the power battery. More specifically, the flexible layer 23 is a sponge layer.

[0051] Furthermore, combined Figure 2 and Figure 6 As shown, a baffle 24 is connected to the upper end of the push plate 40, and the baffle 24 is located on the side of the push plate 40 facing away from the power battery. The push plate 40 is connected to the sliding member 22 through the baffle 24, which helps to improve the stability of the push plate 40.

[0052] In some implementations, combined Figure 2 , Figure 6 and Figure 7 As shown, the system also includes a cleaning component 60 and a transmission component 70. The cleaning component 60 is slidably disposed relative to the housing 20, and the cleaning component 60 is in contact with the surface of the housing 20. The push drive component 50 forms a transmission engagement with the cleaning component 60 via the transmission component 70, enabling the cleaning component 60 to slide relative to the housing 20. Specifically, when the cleaning component 60 is in contact with the surface of the housing 20, the sliding of the cleaning component 60 relative to the housing 20 allows for contact with a larger surface area of ​​the housing 20, thereby effectively cleaning dust or dirt from the outside of the housing 20. Since the driving force of the push drive component 50 drives the cleaning component 60 to slide relative to the housing 20, a separate power source for the cleaning component 60 is avoided, thus simplifying the overall structure of the power battery storage rack 100 suitable for new energy electric vehicle swapping stations. Furthermore, by setting up the cleaning component 60, automatic cleaning of the outer wall of the housing 20 is achieved, eliminating the need for regular cleaning by personnel and greatly reducing manual labor intensity.

[0053] In some implementations, combined Figure 6As shown, the transmission assembly 70 includes a first wheel 71, a linkage 72, and a second wheel 73. The first wheel 71 is connected between the push drive 50 and the push plate 40. The linkage 72 is connected between the first wheel 71 and the second wheel 73. The second wheel 73 and the cleaning assembly 60 form a transmission fit that allows the cleaning assembly 60 to slide relative to the housing 20. Specifically, the output shaft 51 of the push drive 50 is connected to the first wheel 71 and the push plate 40. When the output shaft 51 of the push drive 50 rotates, the first wheel 71 rotates with the output shaft 51 of the push drive 50. The first wheel 71 drives the second wheel 73 to rotate through the linkage 72. Finally, the second wheel 73 drives the cleaning assembly 60 to slide relative to the housing 20. By adjusting the outer diameter relationship between the first wheel 71 and the second wheel 73, the movement range of the cleaning assembly 60 relative to the housing 20 can be adjusted.

[0054] In some implementations, combined Figure 6 As shown, the first wheel 71 and the second wheel 73 form a friction transmission engagement through the linkage 72. Specifically, the first wheel 71 and the second wheel 73 are pulleys, and the linkage 72 is a transmission belt. The linkage 72 is respectively sleeved on the first wheel 71 and the second wheel 73.

[0055] In some embodiments, the first wheel 71 is engaged with the second wheel 73 via a linkage 72 to form a gear transmission connection. Specifically, the first wheel 71 and the second wheel 73 are gears, and the linkage 72 meshes with the first wheel 71 and the second wheel 73 respectively.

[0056] In some implementations, combined Figure 2 and Figure 6 As shown, the transmission assembly 70 includes a first transmission rod 74, which is rotatably disposed relative to the housing 20 in the circumferential direction. A transmission engagement is formed between the push drive member 50 and the first transmission rod 74, enabling the first transmission rod 74 to rotate circumferentially. The length direction of the first transmission rod 74 is parallel to the surface of the housing 20, and the first transmission rod 74 forms a threaded engagement with the cleaning assembly 60. Specifically, since the length direction of the first transmission rod 74 is parallel to the surface of the housing 20, when the first transmission rod 74 rotates in its own circumferential direction, the cleaning assembly 60 moves relative to the housing 20 in the length direction of the first transmission rod 74, and the cleaning assembly 60 can remain in contact with the surface of the housing 20 during the movement. In one embodiment, the first transmission rod 74 is a lead screw.

[0057] In some implementations, combined Figure 6 and Figure 7As shown, the transmission assembly 70 further includes a second transmission rod 75, which forms a motion transmission engagement with the pushing drive member 50. The second transmission rod 75 and the first transmission rod 74 form a transmission engagement that allows the first transmission rod 74 to rotate circumferentially. The included angle between the first transmission rod 74 and the second transmission rod 75 is less than 180°. Specifically, by providing the second transmission rod 75, the positional difference or angle between the first transmission rod 74 and the pushing drive member 50 can be accommodated, allowing the driving force of the pushing drive member 50 to be transmitted to the first transmission rod 74. In one embodiment, the end of the first transmission rod 74 near the second transmission rod 75 meshes with the end of the second transmission rod 75 near the first transmission rod 74, forming a stable transmission engagement between the second transmission rod 75 and the first transmission rod 74. More specifically, bevel teeth are distributed at the ends of the first transmission rod 74 and the second transmission rod 75, respectively. In another embodiment, the driving force is transmitted between the first transmission rod 74 and the second transmission rod 75 via bevel gears.

[0058] In some embodiments, the transmission assembly 70 further includes a bracket, on which the first transmission rod 74 and the second transmission rod 75 are respectively mounted. Within the bracket's constraints, the first transmission rod 74 can rotate circumferentially, and the second transmission rod 75 can rotate circumferentially.

[0059] In some implementations, combined Figure 6 As shown, the second transmission rod 75 is connected to the second wheel body 73. Further, the axis of the second transmission rod 75 coincides with the axis of the second wheel body 73. In other embodiments, the driving force of the driving device can be transmitted to the first transmission rod 74 through other structures. In one embodiment, the length direction of the first transmission rod 74 is perpendicular to the length direction of the second transmission rod 75.

[0060] In some implementations, combined Figure 6 and Figure 7 As shown, the transmission assembly 70 also includes a screw 76, which is connected to the output shaft 51 of the push drive member 50. The screw 76 is also threaded through the slide portion 223 of the slider 22, thereby forming a threaded transmission relationship between the slide portion 223 and the output shaft 51 of the push drive member 50. When the screw 76 rotates circumferentially, the slider 22 can move linearly. In one embodiment, the output shaft 51 of the push drive member 50 is connected to one side of the first wheel body 71, and the screw 76 is connected to the other side of the first wheel body 71. Furthermore, the centerlines of the output shaft 51 of the push drive member 50, the first wheel body 71, and the screw 76 are aligned.

[0061] In some implementations, combined Figure 2 and Figure 6As shown, the cleaning assembly 60 includes a main scraper 61, with a threaded connection between the first transmission rod 74 and the main scraper 61. The cleaning assembly 60 also includes a brush body 62, which can be connected to the side of the main scraper 61 facing the surface of the housing 20, thereby enabling the brush body 62 to clean the surface of the housing 20. Specifically, the cleaning assembly 60 includes a side scraper 63 connected to the main scraper 61, with the brush body 62 connected to the side of the side scraper 63 facing the surface of the housing 20. The side scraper 63 and the main scraper 61 can form a certain angle. Specifically, the size of the angle between the main scraper 61 and the side scraper 63 is determined according to the surface shape of the housing 20. By providing the side scraper 63, a larger area of ​​the housing 20 surface can be cleaned.

[0062] In one implementation, combined Figure 2 As shown, the main scraper block 61 is connected to a connecting ring 64 and a connecting block 65. The connecting ring 64 is threaded onto the first transmission rod 74. The connecting block 65 is connected between the main scraper block 61 and the connecting ring 64.

[0063] In some implementations, combined Figures 2 to 4 As shown, the power battery storage rack 100 suitable for new energy electric vehicle battery swapping stations also includes a base 32, with a platform 30 disposed on the upper side of the base 32. Specifically, the base 32 provides support for the platform 30. In some embodiments, the power battery storage rack 100 suitable for new energy electric vehicle battery swapping stations also includes a mounting frame 33, which is connected between the base 32 and the housing 20 to fix the base 32 and the housing 20 relatively.

[0064] In some implementations, combined Figures 2 to 4 As shown, the power battery storage rack 100 suitable for new energy electric vehicle battery swapping stations also includes a buffer assembly 80. The platform 30 is vertically mounted on the upper side of the base 32 under the guidance of the buffer assembly 80. The buffer assembly 80 also elastically abuts against the base 32 and the platform 30. Specifically, since the platform 30 has vertical movement space relative to the base 32, when the power battery presses down onto the platform 30, the platform 30 descends. The elasticity of the buffer assembly 80 suppresses the descent of the platform 30, thereby providing stable support for the power battery and reducing the impact between the power battery and the platform 30, preventing damage to the bottom of the power battery.

[0065] In some implementations, combined Figure 4 and Figure 5As shown, the buffer assembly 80 includes a linear telescopic member 81, one end of which is connected to the base 32, and the other end is connected to the lower surface of the platform 30. Specifically, the length of the linear telescopic member 81 can extend and retract, and the carrier is raised and lowered relative to the base 32 by limiting the direction of extension and retraction of the linear telescopic member 81. In one embodiment, the linear telescopic member 81 is formed by two tubular members nested together.

[0066] In some implementations, combined Figure 4 and Figure 5 As shown, the buffer assembly 80 includes an elastic element 82, which is connected to the platform 30 and transmits a spring force to the platform 30 to suppress its descent. Specifically, when the platform 30 descends relative to the base 32, the deformation amplitude of the elastic element 82 increases, and at the same time, the spring force acting on the platform 30 increases, thereby enabling the platform 30 to maintain a stable height after descending a certain distance relative to the base 32.

[0067] Furthermore, the elastic element 82 is a compressible elastic element 82, with one end abutting against the base 32 and the other end abutting against the lower surface of the platform 30. Furthermore, the compressible elastic element 82 is sleeved on the outer periphery of the linear telescopic element 81, reducing the space occupied by the linear telescopic element 81 and the elastic element 82, and improving the structural compactness of the buffer assembly 80.

[0068] In some implementations, combined Figure 2 and Figure 4 As shown, the base 32 has a recess 321 located on the underside of the stage 30. The recess 321 is used to accommodate the buffer assembly 80, thereby improving the compactness between the base 32 and the stage 30. More specifically, the stage 30 can be partially accommodated within the upper opening of the recess 321.

[0069] Furthermore, combined Figures 2 to 4 As shown, the base 32 has a limiting groove 322 around the groove 321, and the outer periphery of the platform 30 is connected to a limiting protrusion 34. The position of the limiting groove 322 corresponds to the position of the limiting protrusion 34. When the platform 30 descends until the limiting protrusion 34 is just positioned to accommodate the limiting groove 322, the platform 30 is simultaneously positioned relative to the base 32 at a predetermined position, which facilitates the pusher plate 40 accurately abutting against the predetermined part of the power battery. At the same time, the cooperation between the limiting groove 322 and the limiting protrusion 34 restricts the platform 30 from moving with the bottom of the power battery, ensuring that the power battery can smoothly leave the upper surface of the platform 30.

[0070] In some implementations, combined Figure 2 and Figure 4 As shown, the substrate 21 is fixedly connected to the upper side of the base 32.

[0071] In some implementations, combined Figure 4 and Figure 6 As shown, the power battery storage rack 100 suitable for new energy electric vehicle battery swapping stations also includes a mounting plate 25 connected to the base plate 21. The main body of the push drive 50 is connected to the mounting plate 25. The output shaft 51 of the push drive 50 passes through the mounting plate 25 and is connected to the first wheel body 71.

[0072] In some embodiments, the push drive 50 is a motor. By rotating the output shaft 51 of the push drive 50 in both directions, the push plate 40 or the cleaning assembly 60 can be moved back and forth.

[0073] In some implementations, combined Figures 2 to 5 As shown, the power battery storage rack 100 suitable for new energy electric vehicle battery swapping stations also includes a limiting component 90. The limiting component 90 has limiting members 91, with at least two limiting members 91 being relatively movable between each other. The pick-and-place station 31 is located between at least two limiting members 91. The change in the distance between the limiting members 91 is coordinated with the lifting and lowering of the platform 30. Specifically, the lifting and lowering of the platform 30 causes a change in the distance between the limiting members 91. When the platform 30 descends due to the gravity of the power battery, the distance between the two limiting members 91 decreases, and they move closer to both ends of the power battery. When both ends of the power battery are abutted by the limiting members 91, the power battery can only move relative to the platform 30 in a predetermined direction, thereby improving the stability of the power battery movement process.

[0074] In some implementations, combined Figure 4 and Figure 5 As shown, the limiting assembly 90 also includes a crossbar 92, a toothed ring 93, and a rack 94. The crossbar 92 is rotatably mounted on the base 32. The toothed ring 93 is connected to the outer periphery of the crossbar 92. The rack 94 is connected to the platform 30. The rack 94 meshes with the toothed ring 93. The crossbar 92 is threadedly engaged with at least one limiting member 91. Specifically, the rack 94 moves up and down relative to the base 32 as the platform 30 moves. The outer periphery of the toothed ring 93 has protruding teeth. When the platform 30 moves up and down, the rack 94 drives the toothed ring 93 to rotate. Since the crossbar 92 is fixed circumferentially relative to the toothed ring 93, the crossbar 92 rotates with the toothed ring 93. When the circumferential position of the limiting member 91 relative to the crossbar 92 is limited, the rotation of the crossbar 92 can cause the limiting member 91 to move axially along the crossbar 92 through the thread. More specifically, the upper end of the rack 94 is connected to the lower surface of the platform 30.

[0075] In one implementation, combined Figures 2 to 4As shown, each end of the crossbar 92 is fitted with a limiting member 91. The pick-and-place station 31 is located between these two limiting members 91, and the threads at both ends of the crossbar 92 are in opposite directions. When the crossbar 92 rotates circumferentially, the two limiting members 91 move simultaneously toward or away from the pick-and-place station 31. In one embodiment, the toothed ring 93 may be integrally formed with the crossbar 92.

[0076] In some implementations, combined Figure 2 and Figure 3 As shown, the limiting member 91 includes a clamping plate portion 911, a support rod portion 912, and a collar portion 913. The clamping plate portion 911 is used to contact the power battery. The width of the clamping plate portion 911 is greater than that of the support rod portion 912 or the collar portion 913. The support rod portion 912 is connected between the clamping plate portion 911 and the collar portion 913. The collar portion 913 is threaded onto the crossbar 92. Further, a groove can be formed using a plate component, the extension direction of which is parallel to the length direction of the crossbar 92. The support rod portion 912 is slidably disposed in the groove, thereby limiting the circumferential position of the limiting member 91 relative to the crossbar 92. Further, the side of the clamping plate portion 911 near the pick-and-place station 31 is covered with a flexible plate 914 to prevent the clamping plate portion 911 from scratching the surface of the power battery. More specifically, the flexible plate 914 is a sponge plate.
