Description

Technical Field

[0001] This application relates to the field of battery swapping station technology, and in particular to a skid-mounted battery swapping station. Background Technology

[0002] In response to the global call for energy conservation and emission reduction, fuel-powered machinery has been gradually replaced by electric machinery in recent years. Battery swapping stations have emerged in the market, providing direct battery exchange for electric vehicles. These stations store multiple fully charged battery packs. Vehicles with depleted batteries can drive to the station, unload the depleted battery pack into the station's battery compartment, and load the fully charged battery pack into the vehicle. However, many battery swapping stations do not have charging facilities for the battery packs. When the fully charged batteries in the battery compartment are depleted, a battery transport vehicle is needed to deliver fully charged batteries, and the depleted batteries need to be transported to a designated location for centralized charging. This undoubtedly increases transportation costs and is not conducive to energy conservation.

[0003] In view of this, the present invention is hereby proposed. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0050] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] See Figure 7 and Figure 8 As shown, a skid-mounted battery swapping station includes:

[0052] The charging compartment 200 includes a charging base box and an upper shell, the upper shell being detachably connected to the charging base box; the charging base box has a cavity, and an exhaust duct is provided inside the cavity;

[0053] A battery swapping compartment 100 is disposed near the charging compartment. The battery swapping compartment includes a base frame and a compartment shell, and the compartment shell is detachably connected to the base frame.

[0054] The driving lane 300 is located close to the battery swapping compartment and has space to accommodate battery swapping vehicles.

[0055] The skid-mounted battery swapping station in this solution has a detachable and quick-assembly structure, enabling rapid assembly and disassembly in different ground environments.

[0056] The charging compartment 200 and the battery swapping compartment 100 are described in detail below.

[0057] See Figures 1 to 6As shown in the illustration, this application provides a charging compartment 200, including: a charging base box 210, an upper casing 230, and multiple chargers 220. The charging base box 210 has multiple lifting legs 211 for leveling the charging base box 210. Multiple battery bases 212 are disposed on the top of the charging base box 210. Each charger 220 is disposed inside the charging base box 210 and is electrically connected to the battery base 212 to charge the battery box mounted on the battery base 212. For example, the battery base 212 has a charging terminal for charging the battery box, and the charger is directly electrically connected to this charging terminal. A power connection terminal is provided at the bottom of the battery box; when the battery box is mounted on the battery base, the charging terminal and the power connection terminal are directly electrically connected to achieve charging. The upper casing 230 is detachably connected to the charging base box 210 and covers each of the battery bases 212.

[0058] The charging compartment 200 of this application can not only temporarily store depleted battery boxes removed from the battery swapping vehicle, but also charge the removed depleted battery boxes without having to be transported to other stations for charging, thus reducing transportation costs. The upper casing 230 can cover each battery base 212, providing protection for the battery box and charger 220.

[0059] In one possible implementation, see Figure 3 and Figure 4 As shown, the upper housing 230 and the charging base 210 enclose a battery storage cavity. A battery swapping clearance opening 233 communicating with the battery storage cavity is provided on one side of the upper housing 230. The upper housing 230 has a top wall 231, which is inclined. The side of the top wall 231 located near the battery swapping clearance opening 233 is higher, while the side of the top wall 231 furthest from the battery swapping clearance opening 233 is lower.

[0060] In this implementation scheme, the top wall 231 is inclined to facilitate drainage and prevent rainwater from seeping into the charging compartment 200. The battery swapping station also has a battery swapping compartment, in which a battery swapping robot is installed, and a battery swapping avoidance opening 233 connects to the battery swapping compartment. In this application, the top wall 231 is positioned higher on one side of the battery swapping avoidance opening 233, preventing rainwater from flowing into the gap between the charging compartment 200 and the battery swapping compartment, thus avoiding a large amount of rainwater entering the battery swapping station and pouring onto the battery swapping robot performing its task, thereby improving safety.

[0061] In one possible implementation, see Figure 4 As shown, a water collection trough 2312a is provided on the top wall 231, and the water collection trough 2312a is located on the side of the top wall 231 away from the battery swapping avoidance opening 233.

[0062] During rainy or snowy weather, rainwater will flow along the top wall 231 into the water collection trough 2312a, which facilitates the smooth discharge of rainwater.

[0063] In one possible implementation, see Figure 3 and Figure 4 As shown, the upper housing 230 has side walls, and the top wall 231 includes a main body 2311 and a water collection plate 2312. The main body 2311 is connected to the side wall, and the battery swapping clearance opening 233 is formed between the main body 2311 and the side wall. The water collection plate 2312 is connected to the side wall, and the water collection plate is located on the side of the main body 2311 away from the battery swapping clearance opening 233. The water collection plate 2312 has the water collection groove 2312a. The main body 2311 is inclined from the side of the battery swapping clearance opening 233 towards the side of the water collection plate 2312.

[0064] In one possible implementation, the charging compartment 200 further includes a drain pipe 240 connected to the water collection tank 2312a. Liquid accumulated in the water collection tank 2312a can be drained through the drain pipe 240.

[0065] In one possible implementation, the upper housing 230 is provided with adapter boxes 250 at both ends of the water collection tank 2312a, the adapter boxes 250 are connected to the water collection tank 2312a, and the drain pipe 240 is connected to the adapter boxes 250.

[0066] In this implementation scheme, the adapter box 250 serves as a buffer and confluence point. The design of the adapter box 250 facilitates the connection of the drain pipe 240 to the water collection tank and makes the connection and assembly of the drain pipe 240 easier.

[0067] In one possible implementation, see Figure 4 As shown, the upper housing 230 is provided with a plurality of fasteners 260 for fixing the drain pipe 240, and each fastener 260 is arranged at intervals along the length of the drain pipe 240. The two ends of the fasteners are fixed to the upper housing 230, and the middle part is pressed against the drain pipe 240.

[0068] In one possible implementation, see Figure 1 and Figure 2 As shown, the charging base box 210 is provided with a guide component 213. During the process of the upper box shell 230 being installed into the charging base box 210, the upper box shell 230 slides along the guide component 213 until it is supported by the charging base box 210.

[0069] In this implementation scheme, the guide component 213 facilitates accurate assembly of the upper housing. A lifting ring can be installed on the upper housing for lifting and lowering using hoisting equipment.

[0070] In one possible implementation, the guide component 213 has an upwardly convex arc-shaped guide surface, and the bottom of the upper housing 230 is provided with a guide mating hole 232. During the process of installing the upper housing 230 onto the charging base box 210, the guide component 213 can be inserted into the guide mating hole 232.

[0071] In one possible implementation, the charging base 210 has an upper wall, and the lifting leg 211 has a supporting shell with a flat top wall that is higher than the upper wall. When the upper shell 230 is installed in the charging base 210, the upper shell 230 is supported by the flat top wall, and there is a gap between the upper shell 230 and the upper wall. The gap between the bottom surface of the upper shell 230 and the top surface of the upper wall prevents manufacturing errors from affecting assembly.

[0072] In one possible implementation, see Figure 5 and Figure 6 As shown, the charging compartment 200 also includes an exhaust duct 215. The charging base box 210 has a cavity, the exhaust duct 215 is disposed in the cavity, and each of the chargers 220 is disposed in the cavity. Each of the chargers 220 is connected to the exhaust duct 215.

[0073] The heat generated by the charger 220 enters the exhaust duct 215 and is eventually discharged from the charging base box 210, ensuring that the charging base box 210 operates at a low temperature, so that the charger 220 can maintain good working conditions.

[0074] In one possible implementation, each charger 220 is disposed on both sides of the exhaust duct 215, and the chargers 220 are arranged sequentially along the length of the exhaust duct 215. The chargers 220 are disposed on both sides of the exhaust duct 215 and are arranged neatly, making full use of the internal space.

[0075] Multiple battery bases are arranged along the length of the top of the charging base box 210, and each charger inside the charging base box 210 is electrically connected to each of the battery bases via a power supply cable.

[0076] In one possible implementation, see Figure 6 As shown, the bottom of the exhaust duct 215 is connected to a bracket 216, which supports the exhaust duct 215. The exhaust duct 215 has a bottom wall with multiple connecting ports, and each charger 220 is connected to a corresponding connecting port on the bottom wall.

[0077] In this implementation scheme, the exhaust pipe is suspended by the bracket 216, which facilitates the connection of the charger 220 to the connection port on the bottom wall through the pipe. The width dimension of the battery swapping station occupied by all the chargers 220 and exhaust pipes 215 is small, which helps to reduce the width of the charging box 210.

[0078] In one possible implementation, the charging compartment 200 includes two exhaust ducts 215, which are arranged sequentially along the length of the charging base box 210. Each exhaust duct 215 is equipped with an air outlet and a fan. By providing two exhaust ducts 215, the extension length of each exhaust duct is shortened, which facilitates faster airflow under the same fan drive.

[0079] In one possible implementation, the charging base box 210 is provided with a grid window 214 corresponding to each of the exhaust ducts 215, and each of the exhaust ducts 215 extends to the corresponding grid window 214 and is provided with the air outlet at its end.

[0080] In this implementation scheme, the design of the grid window 214 facilitates the direct discharge of hot air to the outside through the air outlet at the end of the exhaust pipe.

[0081] See Figures 9 to 13 As shown in the illustration, this application provides a battery swapping bay 100, including: a base frame 8, a bay shell 1, a battery storage seat 7, and a battery swapping robot 9. The bay shell 1 is detachably connected to the base frame 8, and the bay shell 1 has a cavity. The battery storage seat 7 is disposed within the cavity. The battery swapping robot 9 is movably disposed within the bay shell 1, and the battery swapping robot 9 can grasp battery boxes and temporarily store them in the battery storage seat 7.

[0082] The skid-mounted battery swapping station includes a battery swapping compartment 100 and a charging compartment. The charging compartment contains multiple battery box mounting brackets for securing the battery boxes and charging them. In this embodiment, a battery box storage seat 7 is provided within the casing 1 of the battery swapping compartment 100 to temporarily store depleted battery boxes removed from vehicles awaiting battery swapping. This eliminates the need to reserve empty space within the charging compartment of the skid-mounted battery swapping station, allowing the charging compartment to maintain a fully loaded battery box state, thus fully utilizing the space of the battery swapping compartment 100 and increasing the battery box loading capacity of the charging compartment.

[0083] In one possible implementation, see Figure 9 and Figure 13As shown, the battery swapping compartment 100 includes two battery storage seats 7. The compartment shell 1 has a side wall 11 and a top wall 13. The side wall 11 extends along the edge of the bottom frame 8. The top wall 13 is connected to the side wall 11. A doorway 12 is provided on the side wall 11. The two battery storage seats 7 are located in the cavity and are respectively located on both sides of the doorway 12.

[0084] The battery swapping compartment 100 and the charging compartment are arranged parallel to each other. A doorway 12 is provided on the side of the battery swapping compartment 100 facing away from the charging compartment, and the side of the battery swapping compartment 100 facing the charging compartment is an open side, which is connected to the charging compartment. The battery swapping robot 9 has a gripping mechanism for grasping battery boxes. The gripping mechanism includes a multi-stage telescopic arm 91 and a gripper 92. The gripper 92 is connected to the end of the multi-stage telescopic arm 91, which can extend and retract along the width of the battery swapping compartment 100. During the battery swapping process, the multi-stage telescopic arm 91 of the battery swapping robot 9 extends out of the doorway 12, allowing the gripper 92 to contact and grasp the depleted battery box on the vehicle to be swapped. Then, the battery swapping robot 9 controls the multi-stage telescopic arm 91 to retract the battery box from the doorway 12 into the cavity for storage in the battery box temporary storage seat 7. Subsequently, the battery swapping robot 9 moves horizontally along the length of the battery swapping compartment to the target position and controls the multi-stage telescopic boom 91 to extend to one side of the charging compartment to grab the target battery box inside the charging compartment using a gripper. Then, the multi-stage telescopic boom 91 drives the fully charged battery box to retract into the cavity. The battery swapping robot moves to the position between the two battery box temporary storage seats 7, that is, the position directly opposite the doorway 12, which can also be used as a power supply station. At this position, the battery swapping robot controls the multi-stage telescopic boom 91 to extend the fully charged battery box out of the doorway to load the battery box onto the battery swapping vehicle. Finally, the battery swapping robot grabs the depleted battery box stored on the battery box temporary storage seat and loads it into the battery box fixing seat in the charging compartment to charge the battery box.

[0085] By setting up temporary battery storage seats on both sides of the battery swapping station, the battery swapping robot can place the battery box it grabs from the vehicle to be swapped onto the corresponding temporary storage seat, based on the location of the target fully charged battery box. For example, when the battery swapping robot needs to grab a fully charged battery box located on the left side of the battery swapping station, it can first grab a depleted battery box from the vehicle to be swapped and place it on the temporary storage seat on the right side of the battery swapping station, without obstructing the robot's subsequent movement path. This facilitates the smooth completion of the battery swapping task by the battery swapping robot.

[0086] In one possible implementation, the housing 1 has a bottom wall 15, the side wall 11 is connected to the bottom wall 15, and the battery storage seat 7 is fixed to the bottom wall 15.

[0087] A door 2 is provided on the side wall 11, and the door 2 is slidably connected to the side wall 11 to open or close the door opening 12.

[0088] The bottom wall 15 has multiple first-direction bottom beams, which can extend along the length of the battery swapping compartment. Adjacent first-direction beams are connected by second-direction beams, which are perpendicular to the first-direction beams. The battery storage seat 7 is positioned perpendicular to the first-direction beams, supported on the first-direction beams, and fixed to the second-direction beams by fasteners. A panel layer covers the bottom wall 15 on the first and second-direction beams, and fasteners pass through the panel layer and are connected to the second-direction beams.

[0089] The battery swapping compartment 100 also includes two guide rails 16, which are spaced apart on the bottom wall 15. The battery storage seat 7 is located between the two guide rails 16, and the battery swapping robot 9 is slidably connected to the two guide rails 16. The battery storage seat 7 does not interfere with the operation of the battery swapping robot.

[0090] Optionally, the sidewall 11 includes a first sidewall and two second sidewalls, located at both ends of the battery swapping compartment along its length. The first sidewall connects to the two second sidewalls, and the top wall 13 connects to both the first sidewall and the two second sidewalls. The side of the compartment shell 1 opposite to the first sidewall is an open side. The battery swapping robot 9 has a gripping mechanism that can extend and retract bidirectionally along a direction perpendicular to the first sidewall to extend or retract the open side / doorway 12.

[0091] The battery swapping compartment 100 also includes a cover 14, and a hoisting clearance hole 132 is provided on the top wall 13. The cover 14 is detachably connected to the top wall 13 to close or open the hoisting clearance hole 132.

[0092] The battery swapping compartment 100 of this application has a lifting clearance hole 132 on its top wall 13, which facilitates the assembly of the battery swapping robot 9. A lifting rope is connected to the battery swapping robot, passing through the lifting clearance hole 132 and connecting to a lifting device. The operator uses a translation mechanism to first insert one long side of the battery swapping robot 9 into the cavity, positioning it below the lifting clearance hole 132. The lifting device then lifts the battery swapping robot 9, rotates it 90 degrees to make it upright (when the battery swapping robot 9 is in the upright position, its long side is perpendicular to the length direction of the battery swapping compartment 100). The lifting device then lowers the battery swapping robot 9 to complete its assembly. The cover 14 can close the lifting clearance hole 132 after the battery swapping robot 9 is assembled to prevent rainwater from seeping into the battery swapping compartment 100.

[0093] In one possible implementation, a light-transmitting groove is formed in the middle of the cover 14, and a light-transmitting plate is connected to the cover 14, covering the light-transmitting groove. Through the design of the light-transmitting plate, sunlight can pass through it and illuminate the battery swapping compartment 100, resulting in better lighting inside the compartment.

[0094] Optionally, the base frame 8 is provided with a guide component (not shown). During the process of the compartment shell 1 being installed into the base frame 8, the compartment shell 1 can slide along the guide component until it is supported by the base frame 8. Optionally, the guide component has an upwardly convex arc-shaped guide surface, and the bottom of the compartment shell 1 is provided with a guide mating hole (not shown). During the process of the compartment shell 1 being installed into the base frame 8, the guide component can be inserted into the guide mating hole.

[0095] In this implementation scheme, guide components are provided to facilitate accurate assembly of the silo shell 1. Lifting rings can be installed on the silo shell 1 for lifting and lowering using lifting equipment.

[0096] The battery swapping robot 9's gripping mechanism also includes a lifting mechanism, which is located at the end of the multi-stage telescopic boom 91. The gripper 92 is connected to the lifting mechanism, which drives the gripper 92 to move up and down, enabling it to grip or release the battery box. When gripping a battery box, the multi-stage telescopic boom 91 extends and retracts, positioning the gripper 92 directly above the battery box. Then, the lifting mechanism lowers the gripper 92 to contact and grip the battery box. Subsequently, the lifting mechanism raises the gripper 92 to lift the battery box. When transferring the battery box to the battery box mounting base or battery box temporary storage base 7, the multi-stage telescopic boom 91 first retracts the battery box. Then, the entire battery swapping robot 9 moves along the track to the target position. The multi-stage telescopic boom 91 extends again, positioning the gripper 92 directly above the corresponding battery box temporary storage base 7 or battery box mounting base. Then, the lifting mechanism lowers the gripper 92 to load the battery box into the battery box temporary storage base 7 or battery box mounting base, and the gripper 92 releases the battery box.

[0097] It should be noted that the battery swapping robot has been patented and published, and its specific structure will not be described in detail here. Furthermore, various forms of battery swapping robots are applicable to this application, and this application does not limit the specific structure of the battery swapping robot.

[0098] In one possible implementation, see Figure 4 As shown, the battery storage holder 7 has a horizontal frame 71 and a guide assembly protruding from the horizontal frame 71. The battery box can slide along the guide assembly onto the horizontal frame 71.

[0099] The battery swapping robot 9 is also equipped with a lifting mechanism, and the gripper 92 is connected to the lifting mechanism. The lifting mechanism can drive the gripper 92 to move up and down. When it is necessary to put the battery box into the battery box temporary storage seat 7, the multi-stage telescopic boom 91 is first in the retracted state. The lifting mechanism (which may include a lifting rope) gradually lowers the gripper 92 to contact the battery box with the guide assembly and gradually falls along the guide body 72 until it is stably supported on the battery box temporary storage seat 7.

[0100] In one possible implementation, the guiding assembly includes a plurality of guide bodies 72, each guide body 72 being distributed at different positions on the frame body, and each guide body 72 having an inclined guiding surface. The battery box can slide down the bottom periphery along the guiding surface until it is stably supported by the horizontal frame 71 of the battery box temporary storage seat 7. In addition to its guiding function, the guide body 72 also serves a limiting function, preventing the battery box from shifting or tilting.

[0101] In another embodiment,

[0102] See Figure 14 As shown in the illustration, this application provides a skid-mounted battery swapping station, comprising: a support unit (which may be a charging base box 210 as described below), a guide rail 16, and a battery swapping robot 9. The support unit has multiple battery mounting seats 2120 along its length. The guide rail 16 is disposed on one side of the support unit along its width direction and extends along the length direction of the support unit. The battery swapping robot 9 is slidably connected to the guide rail 16. The battery swapping robot 9 has at least two bidirectional telescopic mechanisms 91, each of which is sequentially arranged along the length direction of the guide rail 16, and each of the bidirectional telescopic mechanisms 91 has a gripper 92 at its end. The bidirectional telescopic mechanisms 91 can extend and retract bidirectionally in a direction perpendicular to the guide rail 16 to transfer the battery box between the support unit and the battery swapping vehicle. The skid-mounted battery swapping station of this application has two bidirectional telescopic mechanisms 91 on its battery swapping robot 9. One bidirectional telescopic mechanism 91 is used to grab the depleted battery box on the battery swapping vehicle and transfer it to the battery mounting base 2120. The other bidirectional telescopic mechanism 91 is used to grab the fully charged battery box on the battery mounting base 2120 and load it into the battery swapping vehicle. Through the coordinated operation of the two bidirectional telescopic mechanisms 91, the battery swapping efficiency is significantly improved.

[0103] Furthermore, by setting two bidirectional telescopic mechanisms 91 on the battery swapping robot 9, the robot can grab the depleted battery box and the fully charged battery box respectively. This eliminates the need to reserve empty battery fixing seats 2120 on the support part during the battery swapping process, allowing each battery fixing seat 2120 on the support part to maintain a full load of battery boxes, thereby increasing the battery box loading capacity of the charging compartment.

[0104] In one possible implementation, the guide rail 16 has a main guide rail 161 and an extension guide rail 162, the main guide rail 161 and the area on the support where the battery holder is mounted are of equal length, the extension guide rail 162 is disposed at both ends of the main guide rail 161 along the length direction, and the length of the extension guide rail 162 is not less than the extension length of the battery holder 2120.

[0105] In this implementation scheme, when the battery swapping robot 9 is an integrated structure, its length is approximately equal to that of the two battery mounting bases 2120. When the left gripper 92 of the battery swapping robot 9 has grasped a fully charged battery box, while the right gripper 92 needs to grasp a depleted battery box from the battery swapping vehicle, the battery swapping robot 9 needs to move horizontally so that the left gripper 92 faces the battery swapping vehicle to facilitate the loading of the fully charged battery box into the vehicle. When it is necessary to load a depleted battery box into the end of the support section, the battery swapping robot 9 can move to the end of the guide rail 16, that is, the left gripper 92 is located on one side of the extended guide rail 162, and the right gripper 92 is located at the end of the main guide rail 161, making it convenient for the right gripper 92 to load the depleted battery box into the battery mounting base 2120 at the end of the support section. Thus, it can be seen that by setting the extended guide rail 162, it is possible to grasp a fully charged battery box at any position on the support section, facilitating the loading of a depleted battery box into the battery mounting base 2120 at the end of the support section.

[0106] In one possible implementation, the battery swapping robot 9 is provided with a corresponding battery box channel for each of the bidirectional telescopic mechanisms 91. Each battery box channel extends in a direction perpendicular to the guide rail 16, and the bidirectional telescopic mechanism 91 can drive the battery box to move bidirectionally along the battery box channel. The battery box will not collide or interfere with the battery swapping robot 9 during its passage through the corresponding battery box channel.

[0107] In one possible implementation, the battery swapping robot 9 has multiple frame bodies 93, with a battery compartment channel formed between adjacent frame bodies 93. Each of the bidirectional telescopic mechanisms 91 is connected to two adjacent frame bodies 93.

[0108] In another embodiment,

[0109] See Figure 15As shown, Embodiment 2 of this application provides a skid-mounted battery swapping station. The skid-mounted battery swapping station in Embodiment 2 is similar to the skid-mounted battery swapping station in Embodiment 1 in that it also includes a support unit, a guide rail 16, and a battery swapping robot 9. The support unit has multiple battery mounting bases 2120 along its length. The guide rail 16 is located on one side of the support unit along its width direction and extends along the length direction of the support unit. The battery swapping robot 9 is slidably connected to the guide rail 16. The difference is that the battery swapping robot 9 is a separate component, comprising a first battery swapping robot and a second battery swapping robot, which are independent of each other. Both the first and second battery swapping robots are movably mounted on the guide rail 16 and can translate along the guide rail 16. Each battery swapping robot 9 is provided with a bidirectional telescopic mechanism 91. Each bidirectional telescopic mechanism 91 has a gripper 92 at its end. The bidirectional telescopic mechanism 91 can extend and retract bidirectionally along the direction perpendicular to the guide rail 16 to transfer battery boxes between the support and the battery swapping vehicle. One bidirectional telescopic mechanism 91 on the battery swapping robot 9 is used to grab a depleted battery box from the battery swapping vehicle and transfer it to the battery mounting base 2120. The other bidirectional telescopic mechanism 91 on the battery swapping robot 9 is used to grab a fully charged battery box from the battery mounting base 2120 and load it into the battery swapping vehicle. The coordinated operation of the two bidirectional telescopic mechanisms 91 significantly improves the battery swapping efficiency.

[0110] In one possible implementation, both the first and second battery swapping robots have two frame bodies 93, which are spaced apart and form a battery compartment channel between them. The bidirectional telescopic mechanism 91 connects the two frame bodies 93 respectively.

[0111] By setting up two independent battery swapping robots 9, the two robots 9 can operate independently during the battery swapping process, significantly improving work efficiency. For example, the first battery swapping robot can first travel to the battery swapping station in an unloaded state to grab the depleted battery box from the battery swapping vehicle. During this process, the second battery swapping robot can grab the fully charged battery box. After the first battery swapping robot finishes its work, it leaves the battery swapping station, and the second battery swapping robot can travel to the battery swapping station to load the fully charged battery box onto the battery swapping vehicle.

[0112] In another embodiment,

[0113] This application provides a battery swapping method for the skid-mounted battery swapping station described in Embodiments 1 and 2 above, including:

[0114] Step S101: After the skid-mounted battery swapping station receives the battery swapping request from the battery swapping vehicle, it determines the charging position of the fully charged battery box.

[0115] Each battery holder 2120 can hold a battery box, and each battery holder 2120 can charge the battery box mounted on it, that is, each battery holder 2120 provides a charging position.

[0116] Step S102: The skid-mounted battery swapping station drives the first bidirectional telescopic mechanism to grab the fully charged battery box located at the charging position according to the charging position of the fully charged battery box, and drives the second bidirectional telescopic mechanism to grab the depleted battery box located on the battery swapping vehicle.

[0117] Step S103: The skid-mounted battery swapping station drives the first bidirectional telescopic mechanism to store the fully charged battery box onto the battery swapping vehicle, and drives the second bidirectional telescopic mechanism to store the depleted battery box onto the charging position.

[0118] The skid-mounted battery swapping station includes: a charging compartment with multiple charging positions; and a battery swapping compartment for the first and second bidirectional telescopic mechanisms to move laterally along a guide rail 16. The guide rail 16, located within the battery swapping compartment, extends beyond the support portion within the charging compartment by the length of one charging position at each end. Alternatively, the charging compartment may have an empty space of the same size as a charging position at each end, without a battery mounting bracket 2120, and the charging compartment and the battery swapping compartment have the same length.

[0119] This embodiment of the application, after the skid-mounted battery swapping station determines the charging position of the fully charged battery box, further includes: the skid-mounted battery swapping station determining whether the first bidirectional telescopic mechanism and the second bidirectional telescopic mechanism are configured in a separate mode or a combined mode; wherein, the separate mode means that the first bidirectional telescopic mechanism is mounted on the first battery swapping robot, and the second bidirectional telescopic mechanism is mounted on the second battery swapping robot. The combined mode means that both the first bidirectional telescopic mechanism and the second bidirectional telescopic mechanism are mounted on the third battery swapping robot.

[0120] The skid-mounted battery swapping station drives a first bidirectional telescopic mechanism to grab a fully charged battery box located at the charging position of the fully charged battery box, and drives a second bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle. This includes: when the skid-mounted battery swapping station determines that the first and second bidirectional telescopic mechanisms are configured in a split mode, the battery swapping robot 9 closest to the charging position of the fully charged battery box is designated as the first battery swapping robot, and the battery swapping robot 9 not closest to the charging position of the fully charged battery box is designated as the second battery swapping robot. A first instruction is sent to the first battery swapping robot, and a second instruction is sent to the second battery swapping robot. The first battery swapping robot then drives the second battery swapping vehicle according to the first instruction. The first bidirectional telescopic mechanism grabs a fully charged battery box located at the charging position, while the second battery swapping robot, according to a second instruction, drives the second bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle; or, after the first battery swapping robot, according to the first instruction, drives the first bidirectional telescopic mechanism to grab a fully charged battery box located at the charging position, the second battery swapping robot, according to the second instruction, drives the second bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle; or, after the second battery swapping robot, according to the second instruction, drives the second bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle, the first battery swapping robot, according to the first instruction, drives the first bidirectional telescopic mechanism to grab a fully charged battery box located at the charging position.

[0121] The skid-mounted battery swapping station's control of the first bidirectional telescopic mechanism to store a fully charged battery box onto the battery swapping vehicle, and its driving of the second bidirectional telescopic mechanism to store a depleted battery box onto the charging position, includes: the skid-mounted battery swapping station sending a third command to the first battery swapping robot and a fourth command to the second battery swapping robot; the first battery swapping robot driving the first bidirectional telescopic mechanism to store a fully charged battery box onto the battery swapping vehicle according to the third command, while the second battery swapping robot driving the second bidirectional telescopic mechanism to store a depleted battery box onto the charging position according to the fourth command. The battery box is stored at the charging position; or, after the first battery swapping robot drives the first bidirectional telescopic mechanism according to the third instruction to store the fully charged battery box on the battery swapping vehicle, the second battery swapping robot drives the second bidirectional telescopic mechanism according to the fourth instruction to store the depleted battery box on the charging position; or, after the second battery swapping robot drives the second bidirectional telescopic mechanism according to the fourth instruction to store the depleted battery box on the charging position, the first battery swapping robot drives the first bidirectional telescopic mechanism according to the third instruction to store the fully charged battery box on the battery swapping vehicle.

[0122] The skid-mounted battery swapping station drives a first bidirectional telescopic mechanism to grab a fully charged battery box located at the charging position of the fully charged battery box, and drives a second bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle. This includes: when the skid-mounted battery swapping station determines that the first and second bidirectional telescopic mechanisms are configured as a combined mode, it uses the bidirectional telescopic mechanism 91 closest to the charging position of the fully charged battery box as the first bidirectional telescopic mechanism, and simultaneously uses the bidirectional telescopic mechanism 91 not closest to the charging position of the fully charged battery box as the second bidirectional telescopic mechanism, and sends a fifth instruction to the third battery swapping robot; after the third battery swapping robot drives the first bidirectional telescopic mechanism to grab a fully charged battery box located at the charging position according to the fifth instruction, it drives the second bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle; or after the third battery swapping robot drives the second bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle according to the fifth instruction, it drives the first bidirectional telescopic mechanism to grab a fully charged battery box located at the charging position.

[0123] The skid-mounted battery swapping station's control of the first bidirectional telescopic mechanism to store a fully charged battery box onto the battery swapping vehicle, and its driving of the second bidirectional telescopic mechanism to store a depleted battery box onto the charging position, includes: the skid-mounted battery swapping station sending a sixth instruction to the third battery swapping robot; the third battery swapping robot, according to the sixth instruction, driving the first bidirectional telescopic mechanism to store a fully charged battery box onto the battery swapping vehicle, and then driving the second bidirectional telescopic mechanism to store a depleted battery box onto the charging position; or the third battery swapping robot, according to the sixth instruction, driving the second bidirectional telescopic mechanism to store a depleted battery box onto the charging position, and then driving the first bidirectional telescopic mechanism to store a fully charged battery box onto the battery swapping vehicle.

[0124] The battery swapping vehicle is used to send a battery swapping request to the skid-mounted battery swapping station. The skid-mounted battery swapping station, upon receiving the request, determines the charging position of a fully charged battery box. Based on the charging position of the fully charged battery box, it drives a first bidirectional telescopic mechanism to grab the fully charged battery box located at the charging position, and drives a second bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle. It also drives the first bidirectional telescopic mechanism to store the grabbed fully charged battery box on the battery swapping vehicle, and drives the second bidirectional telescopic mechanism to store the grabbed depleted battery box at the charging position.

[0125] In another embodiment,

[0126] In this embodiment, the skid-mounted battery swapping station has two battery swapping robots 9, namely a primary battery swapping robot 9 and a backup battery swapping robot 9. When only one of the primary battery swapping robot 9 and the backup battery swapping robot 9 performs the battery swapping task, it is usually necessary to reserve a battery mounting base 2120 as an empty space to facilitate the storage of the depleted battery box taken out from the battery swapping vehicle.

[0127] The battery swapping methods used in this skid-mounted battery swapping station include:

[0128] Step S101: After the skid-mounted battery swapping station receives the battery swapping request from the battery swapping vehicle, it determines the charging position of the fully charged battery box and judges whether the current main battery swapping robot 9 can work normally.

[0129] Step S102: When the skid-mounted battery swapping station determines that the current main battery swapping robot 9 can work normally, it generates a first battery swapping instruction and sends the first battery swapping instruction to the main battery swapping robot 9, so that the main battery swapping robot 9 completes the battery swapping operation of the battery swapping vehicle according to the first battery swapping instruction.

[0130] Step S103: When the skid-mounted battery swapping station determines that the current primary battery swapping robot 9 cannot work properly, it generates a second battery swapping instruction and sends the second battery swapping instruction to the backup battery swapping robot 9, so that the backup battery swapping robot 9 completes the battery swapping operation of the battery swapping vehicle according to the second battery swapping instruction.

[0131] Specifically, the main battery swapping robot 9 completes the battery swapping operation of the battery swapping vehicle according to the first battery swapping instruction, including: the main battery swapping robot 9 obtains the charging position of the fully charged battery box from the first battery swapping instruction; the main battery swapping robot 9, according to the charging position of the fully charged battery box, grabs the depleted battery box of the battery swapping vehicle to a temporary storage position, grabs the fully charged battery box of the charging position to the battery swapping vehicle, and grabs the depleted battery box of the temporary storage position to the charging position, thereby completing the battery swapping operation of the battery swapping vehicle. The charging position is provided by a battery mounting base 2120, and the temporary storage position can be provided by a battery mounting base 2120 or by a support structure different from the battery mounting base 2120.

[0132] Specifically, the backup battery swapping robot 9 completes the battery swapping operation of the battery swapping vehicle according to the second battery swapping instruction, including: the backup battery swapping robot 9 obtains the charging position of the fully charged battery box from the second battery swapping instruction; the backup battery swapping robot 9 grabs the depleted battery box of the battery swapping vehicle to a temporary storage position according to the charging position of the fully charged battery box, grabs the fully charged battery box of the charging position to the battery swapping vehicle, and grabs the depleted battery box of the temporary storage position to the charging position, thereby completing the battery swapping operation of the battery swapping vehicle.

[0133] The process includes, after determining the charging position of the fully charged battery box, the skid-mounted battery swapping station further includes: detecting whether the temporary storage position for temporarily storing the depleted battery box is available; when the skid-mounted battery swapping station detects that the temporary storage position is unavailable, it generates a third battery swapping instruction and simultaneously sends the third battery swapping instruction to the primary battery swapping robot 9 and the backup battery swapping robot 9, so that the primary battery swapping robot 9 and the backup battery swapping robot 9 complete the battery swapping operation of the battery swapping vehicle according to the third battery swapping instruction.

[0134] The battery swapping operation of the main battery swapping robot 9 and the backup battery swapping robot 9, according to the third battery swapping instruction, includes: the main battery swapping robot 9 and the backup battery swapping robot 9 respectively obtaining the charging position of a fully charged battery box from the third battery swapping instruction; the main battery swapping robot 9, according to the charging position of the fully charged battery box, first grabs a depleted battery box from the battery swapping vehicle and then stores the depleted battery box in the charging position; simultaneously, the backup battery swapping robot 9, according to the charging position of the fully charged battery box, first grabs a fully charged battery box from the charging position and then stores the fully charged battery box in the battery swapping vehicle; or the backup battery swapping robot 9, according to the charging position of the fully charged battery box, first grabs a depleted battery box from the battery swapping vehicle and then stores the depleted battery box in the charging position; simultaneously, the main battery swapping robot 9, according to the charging position of the fully charged battery box, first grabs a fully charged battery box from the charging position and then stores the fully charged battery box in the battery swapping vehicle.

[0135] After determining the charging position of the fully charged battery box at the skid-mounted battery swapping station, the embodiment of the present invention further includes: the skid-mounted battery swapping station determining a battery swapping robot 9 that matches the charging position of the fully charged battery box, and using the swapping robot as the main battery swapping robot 9.

[0136] The skid-mounted battery swapping station, upon receiving a battery swapping request from a battery swapping vehicle, determines the charging position of a fully charged battery box and checks whether the primary battery swapping robot 9 is functioning correctly. If the primary battery swapping robot 9 is functioning correctly, a first battery swapping instruction is generated and sent to the primary battery swapping robot 9. If the primary battery swapping robot 9 is not functioning correctly, a second battery swapping instruction is generated and sent to the backup battery swapping robot 9. The primary battery swapping robot 9 completes the battery swapping operation of the battery swapping vehicle according to the first battery swapping instruction. The backup battery swapping robot 9 completes the battery swapping operation of the battery swapping vehicle according to the second battery swapping instruction.

[0137] The skid-mounted battery swapping station is also used to detect whether the temporary storage space for temporarily storing the depleted battery box is available. When the temporary storage space is detected to be unavailable, a third battery swapping instruction is generated and simultaneously sent to the primary battery swapping robot 9 and the backup battery swapping robot 9, so that the primary battery swapping robot 9 and the backup battery swapping robot 9 can complete the battery swapping operation of the battery swapping vehicle according to the third battery swapping instruction.

[0138] In another embodiment,

[0139] See Figure 14 , Figure 15 , Figure 17 and Figure 18 As shown in the embodiments, this application provides the structure of the bidirectional telescopic mechanism 91 in Embodiments 1 and 2 above. The bidirectional telescopic mechanism 91 includes multiple telescopic frames, adjacent telescopic frames are slidably connected, and a telescopic drive member is connected between adjacent telescopic frames. The telescopic drive member may include a telescopic cylinder, and the telescopic movement of the telescopic cylinder can drive two adjacent telescopic frames to move away from each other or closer together. The telescopic frame at the head end is fixedly connected to two adjacent frame bodies 93, and the gripper 92 is provided on the telescopic frame at the tail end. The gripper 92 has the function of gripping or releasing the battery box.

[0140] In one possible implementation, a lifting mechanism is provided on the telescopic frame at the end, and the gripper is connected to the lifting mechanism, which can drive the gripper to move up and down.

[0141] The bidirectional telescopic mechanism is equipped with a lifting mechanism at its end, and the gripper is connected to the lifting mechanism. The lifting mechanism is used to lift or lower the battery box grasped by the gripper.

[0142] In one possible implementation, the lifting mechanism includes a flexible element, a sliding frame, and a second steering wheel. The sliding frame is slidably connected to the top frame, and a first steering wheel is mounted on the sliding frame. The second steering wheel is fixedly connected to the top frame. One end of the flexible element is fixed to the top frame, such as to a fixed base on the top frame. The flexible element passes around the first and second steering wheels and is then connected to the gripper. The top frame has a clearance hole corresponding to the second steering wheel, through which the flexible element passes. The sliding frame slidably drives the flexible element to lift or lower the gripper. The flexible element can be a lifting rope, wire rope, etc. In this implementation, the lifting or lowering of the gripper can be controlled by controlling the movement of the sliding frame.

[0143] In order to reduce the lifting load of the flexible components and extend their service life, and to facilitate smooth lifting of the battery box, multiple flexible components can be provided in this embodiment. Each flexible component is equipped with a corresponding first steering wheel and a second steering wheel, and the end of each flexible component is connected to a gripper.

[0144] The lifting mechanism also includes a second telescopic component, which is connected to the sliding frame and drives the sliding frame to slide, thereby lifting or lowering the gripper. The second telescopic component can be a telescopic hydraulic cylinder. When the second telescopic component extends, the segment of the flexible member located between the first and second steering wheels becomes longer, while the segment of the flexible member extending downwards vertically from the top frame becomes shorter, thus lifting the gripper. Conversely, when the second telescopic component shortens, the segment of the flexible member extending vertically from the top frame becomes longer, thus lowering the battery box.

[0145] See Figure 14 and Figure 15 As shown, the frame 93 includes two columns 931 spaced apart sequentially along the width of the guide rail. The columns 931 on the same side of the guide rail in any one of the battery swapping robot, the first battery swapping robot, and the second battery swapping robot are connected by a sliding beam 932. The sliding beam 932 is slidably connected to the guide rail. The design of the sliding beam 932 allows for sliding cooperation with the guide rail while also enhancing the structural strength between the two columns 931, resulting in good structural stability of the two frame bodies.

[0146] The sliding beam 932 is equipped with a driving component and multiple rollers, each of which is supported on the guide rail. The driving component and some of the rollers are velocarily connected to drive the battery swapping robot to move along the guide rail. The driving component may include a motor and a gearbox. The input ends of the motor and the gearbox are velocarily connected, and the output end of the gearbox is velocarily connected to at least one of the rollers, driving the rollers to rotate and move the electric battery swapping robot.

[0147] In another embodiment,

[0148] In one possible implementation, see Figures 17 to 25 As shown, the skid-mounted battery swapping station includes a battery swapping compartment 100, which has the aforementioned guide rails and battery swapping robot. The battery swapping compartment 100 also includes side walls, a top wall 13, and a cover 14. The top wall 13 is connected to the side walls, and the top wall 13 and the side walls enclose a cavity, within which the guide rails and battery swapping robot are housed. The top wall 13 is provided with a lifting clearance hole 132 communicating with the cavity. The cover 14 is detachably connected to the top wall 13 to close or open the lifting clearance hole 132.

[0149] A hoisting clearance hole 132 is provided on the top wall 13 of the battery swapping compartment 100 to facilitate the assembly of the battery swapping robot. A hoisting rope is connected to the battery swapping robot, passing through the hoisting clearance hole 132 and connecting to the hoisting equipment. The operator uses a translation mechanism to first insert one long side of the battery swapping robot into the cavity below the hoisting clearance hole. The hoisting equipment lifts the battery swapping robot, rotates it 90 degrees to make it upright (when the battery swapping robot is in the upright position, its long side is perpendicular to the length direction of the battery swapping compartment 100). Then, the hoisting equipment lowers the battery swapping robot to complete the assembly. The cover 14 can close the hoisting clearance hole 132 after the battery swapping robot is assembled to prevent rainwater from seeping into the battery swapping compartment 100.

[0150] In one possible implementation, the top wall 13 has a top frame and a cover plate assembly, the cover plate assembly covering the top frame, and the lifting clearance hole 132 is formed between the cover plate assemblies.

[0151] The cover plate assembly may have a central opening to form the lifting clearance hole 132. Alternatively, the cover plate assembly includes a first side cover plate 133 and a second side cover plate 134. Both the first side cover plate 133 and the second side cover plate 134 cover the top frame. The lifting clearance hole 132 is formed between the first side cover plate 133 and the second side cover plate 134. The first side cover plate 133 and the second side cover plate 134 may both be integral plates. Alternatively, the first side cover plate 133 and the second side cover plate 134 may both be formed by splicing multiple plates.

[0152] In one possible implementation, the top wall 13 has a cover fitting frame 135, which is disposed along the edge of the lifting clearance hole 132, and the cover 14 is detachably connected to the cover fitting frame 135. The design of the cover fitting frame 135 facilitates the assembly and disassembly of the cover 14.

[0153] In one possible implementation, the top wall 13 has a top frame comprising two spaced-apart main beams 131a. The cover fitting frame 135 has two first fitting beams 1351 and two second fitting beams 1352. The two first fitting beams 1351 are vertically connected to the two main beams 131a, and the two second fitting beams 1352 are respectively disposed on the two main beams 131a, with their ends respectively connected to the two first fitting beams 1351. The cover 14 is supported on the first fitting beams 1351 and the second fitting beams 1352. In this implementation, the two first fitting beams 1351 and the two second fitting beams 1352 of the cover fitting frame enclose a U-shaped opening. The fitting beams in both directions provide a stable supporting position for the cover.

[0154] In one possible implementation, the top frame includes a plurality of crossbeams 131b, each of which is connected to two of the main beams 131a. The first mating beam 1351 and one of the crossbeams 131b are fitted together.

[0155] In this embodiment, the first mating beam 1351 can be directly connected and fixed to the crossbeam 131b, which improves the structural strength of the first mating beam 1351. The first mating beam 1351 can be fixed to the crossbeam 131b by welding. Alternatively, the first mating beam 1351 can be fixed to the crossbeam 131b by fasteners.

[0156] In one possible implementation, the cover fitting frame 135 has an upper extension plate 135a. For example, upper extension plates 135a are provided on both the first fitting beam 1351 and the second fitting beam 1352. A lower extension plate (not shown) is provided along one periphery of the cover 14. When the cover 14 is installed on the cover fitting frame 135, the lower extension plate and the upper extension plate 135a are in contact.

[0157] In this embodiment, with the cover 14 installed on the cover fitting frame 135, the lower extension plate can be sleeved on the outside of the upper extension plate 135a. The fit between the upper extension and the lower extension plate defines the position of the cover 14 and prevents the cover 14 from shifting.

[0158] In one possible implementation, a connecting seat 1353 is provided on the cover fitting frame 135. A connecting ear 141 is provided on the edge of the cover 14. The connecting ear 141 is supported on the connecting seat 1353, and the connecting ear 141 and the connecting seat 1353 are detachably connected.

[0159] For example, a fixing hole is provided on the connector 1353, and a through groove is provided on the connector ear 141. One end of the fastener passes through the through groove and is connected to the fixing hole.

[0160] The through groove can be elongated, which solves the problem of misalignment between the through groove and the fixing hole caused by manufacturing errors.

[0161] In one possible implementation, a light-transmitting groove is formed in the middle of the cover 14, and a light-transmitting plate 142 is connected to the cover 14, covering the light-transmitting groove. Through the design of the light-transmitting plate 142, sunlight can pass through it and illuminate the battery swapping compartment 100, resulting in better lighting inside the battery swapping compartment 100.

[0162] In one possible implementation, see Figure 11As shown, the cover 14 is provided with a lifting engagement part 143, which facilitates lifting the cover 14 by lifting equipment. The lifting engagement part may include multiple handles provided on the cover 14.

[0163] In one possible implementation, see Figure 10 As shown, the sidewall includes a first sidewall 111 and two second sidewalls 112, which are spaced apart. The first sidewall 111 connects to the two second sidewalls 112. The top wall 13 connects to the first sidewall 111 and the two second sidewalls 112. The first sidewall 111 and the second sidewalls 112 enclose the cavity. The side of the battery swapping compartment 100 opposite to the first sidewall 111 is an open side. The open side is used to connect to the charging compartment, which is used to load battery boxes and chargers for charging the battery boxes. A doorway is provided on the first sidewall 111. The telescopic arm of the battery swapping robot can extend out of the open side to grab the battery boxes in the battery swapping compartment 100, and can retract and extend further out of the doorway to load the battery boxes onto the battery swapping vehicle. The battery swapping robot can transfer battery boxes from the battery swapping vehicle to the charging compartment for charging, and transfer fully charged battery boxes from the charging compartment to the battery swapping vehicle. The battery swapping robot has a telescopic arm and a gripper at the end of the telescopic arm. The telescopic arm can drive the gripper to extend and retract to grab or release the battery box.

[0164] In another embodiment

[0165] See Figures 26 to 32 As shown in the illustration, this application provides a more detailed description of the battery swapping compartment of a skid-mounted battery swapping station. The compartment includes a casing 1, a door 2, and a battery swapping robot (not shown). The casing 1 encloses a cavity and has a side wall 11 with a doorway 12 communicating with the cavity. The doorway 2 is connected to the side wall 11 and is used to open or close the doorway 12. The battery swapping robot is movably disposed within the casing 1. The battery swapping compartment provided in this application has a casing 1 to protect the internal battery swapping robot, preventing it from being exposed to the environment, and protecting the battery boxes gripped by the robot's grippers. The doorway 12 on the casing 1 facilitates the battery swapping robot's bidirectional telescopic mechanism extending out of the casing 1 to grip or unload the battery boxes. The side of the battery swapping compartment facing away from the doorway is an open side, communicating with a charging compartment, which has a support and a battery mounting base. The charging compartment stores the battery boxes, and a charger is installed inside for charging the battery boxes. The battery swapping robot transports the battery boxes from the battery swapping vehicle to the charging compartment for charging, and then transports the fully charged battery boxes from the charging compartment back to the battery swapping vehicle. The battery swapping robot is equipped with a bidirectional telescopic mechanism and a gripper located at the end of the telescopic arm. The bidirectional telescopic mechanism can drive the gripper to extend and retract, grabbing or releasing the battery boxes.

[0166] In one possible implementation, see Figure 27 As shown, the housing 1 is provided with a slide rail 3, and the door 2 is slidably connected to the slide rail 3. The door 2 can slide along the slide rail 3 to open or close the door opening 12.

[0167] The sliding rail 3 can extend along the length of the side wall. Part of the sliding rail 3 is located at the top or bottom of the doorway, and part extends to other positions on the side wall. The door body slides along the sliding rail 3 to open or close the doorway. The door body 2 can be a single door or a double door structure.

[0168] In one possible implementation, slide rails 3 are respectively provided on the upper and lower sides of the door opening 12 on the shell 1, and the upper and lower sides of the door 2 are slidably connected to the two slide rails 3 respectively.

[0169] In this implementation scheme, slide rails 3 are installed at both the upper and lower parts of the casing 1 to improve the support stability of the door 2. This facilitates the smooth opening or closing of the doorway 12.

[0170] In one possible implementation, a roller assembly 21 is provided on the door body 2, and the slide rail 3 has a guide rail groove, in which the roller assembly 21 is accommodated.

[0171] In this implementation scheme, the roller assembly 21 on the door 2 is slidably supported in the guide rail groove, which defines the position of each roller assembly 21, preventing the roller assembly 21 from disengaging from the slide rail 3. The design of the roller assembly 21 reduces the sliding resistance of the door 2.

[0172] In one possible implementation, the roller assembly 21 includes a bracket 211, a first roller 212, and a second roller 213. The bracket 211 is connected to the door body 2, and both the first roller 212 and the second roller 213 are connected to the bracket 211. The rotation axes of the first roller 212 and the second roller 213 are perpendicular to each other. The rolling surface of the first roller 212 contacts the bottom wall of the guide rail groove, and the rolling surface of the second roller 213 contacts the side wall 11 of the guide rail groove.

[0173] In this implementation scheme, the rotation axes of the first roller 212 and the second roller 213 are perpendicular to each other. The first roller 212 is supported on the bottom wall of the guide rail groove, and the second roller 213 is supported on the side wall 11 of the guide rail, thereby limiting the door body 2 in two directions. The door body 2 has a stable assembly structure and is not easy to shake. During the opening and closing process, the noise generated by the sliding of the door body 2 is small.

[0174] In one possible implementation, both the slide rail 3 and the door 2 are located inside the cavity, making the external structure of the housing 1 flat and preventing external debris from easily entering the guide groove of the slide rail 3. The door 2 and the slide rail 3 can maintain a good sliding fit.

[0175] In one possible implementation, see Figure 28 As shown, the battery swapping compartment also includes a drive mechanism 4, which is connected to the door 2 and drives the door 2 to open or close the door opening 12.

[0176] In this implementation scheme, the drive mechanism 4 can automatically drive the door 2 to open or close, and the degree of automation is high.

[0177] In one possible implementation, the door body 2 is provided with a hinge seat 22 along one side edge of the sliding direction, and the drive mechanism 4 has a telescopic end that is hinged to the hinge seat 22.

[0178] The driving component may include a telescopic cylinder, the end of which is hinged to a hinge seat 22 at the end of the door body 2. The telescopic cylinder extends and retracts, electrically moving the door body 2 along the slide rail 3. Of course, other driving mechanisms may also be used.

[0179] In one possible implementation, the drive mechanism 4 is connected to the side wall 11, which facilitates direct connection to the door body 2 and simplifies the connection structure.

[0180] In one possible implementation, the sidewall 11 has reinforcing longitudinal ribs and a skin covering the reinforcing longitudinal ribs. The drive mechanism 4 also includes a fixing beam 41, which is vertically connected to a plurality of the reinforcing longitudinal ribs. The fixing beam 41 and the plurality of reinforcing longitudinal ribs are connected and fixed, improving the stability of the assembled structure. The fixing beam 41 and the reinforcing longitudinal ribs can be fixed by welding or by fasteners, such as screws.

[0181] In one possible implementation, the telescopic mechanism includes a fixed part 42 and a telescopic part 43. The fixed part 42 is connected to the fixed beam 41, and the telescopic part 43 is connected to the door body 2. The telescopic mechanism may include a telescopic cylinder. The fixed part 42 may be the cylinder barrel of the telescopic cylinder, and the telescopic part 43 may be a telescopic rod connected to the cylinder barrel. The cylinder barrel may be fixed parallel to the fixed beam 41, and the end of the telescopic part is connected to a hinge seat 22 on the door body 2.

[0182] In one possible implementation, see Figures 30 to 32As shown, the casing 1 is equipped with a closed-position sensor 5 and an open-position sensor 6, which can be located on opposite sides of the doorway. The door body 2 is equipped with a first trigger 23 and a second trigger 24. The door body 2 has a closed position (closing the doorway 12) and an open position (opening the doorway 12). When the door body 2 slides to the closed position, the first trigger 23 triggers the closed-position sensor 5. When the door body 2 slides to the open position, the second trigger 24 triggers the open-position sensor 6. In this embodiment, automatic control of opening and closing the door body 2 can be achieved by setting two triggers and two position sensors. The control module is electrically connected to the drive mechanism 4, the closed-position sensor 5, and the open-position sensor 6. Upon receiving an opening command, the control module controls the retraction cylinder of the drive mechanism 4 to retract, moving the door body 2 until the second trigger 24 triggers the open-position sensor 6, at which point the control module controls the drive mechanism 4 to stop moving. Upon receiving a closing command, the control module controls the extension cylinder of the drive mechanism 4 to extend, moving the door 2 until the first trigger 23 triggers the closing position sensor. At this point, the control module stops the drive mechanism 4. The closing position sensor 5 and the opening position sensor 6 can be proximity switches or photoelectric switches. When both sensors are proximity switches, the trigger 2 is activated when it approaches the proximity switch, at which point the control module determines whether the door 2 has accurately reached the closed or open position. When both sensors are photoelectric switches, each sensor can include a transmitter and a receiver. The transmitter emits a signal, and the receiver receives the signal. When the trigger 2 moves between the transmitter and receiver, it blocks the receiver from receiving the signal, at which point the control module determines whether the door 2 has accurately reached the closed or open position.
