During battery swapping, this equipment needs to first grab the depleted battery box from the swapping vehicle, then place the depleted battery box into the charging compartment, and then grab the fully charged battery box from the charging compartment and place the fully charged battery box into the swapping vehicle. It is evident that when battery swapping equipment uses only one telescopic arm gripper, it needs to perform numerous sequential steps, resulting in low swapping efficiency, long waiting times for swapping vehicles, and a poor swapping experience.

[0077] Example 1

[0078] See Figure 1 As shown in the illustration, this application provides a battery swapping device, including a charging base, a guide rail 16, and a battery swapping robot 9. The charging base has multiple battery mounting seats 2120 along its length. The guide rail 16 is located on one side of the charging base along its width direction and extends along its length. 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 of the guide rail 16. Each bidirectional telescopic mechanism 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 pack between the charging base and the battery swapping vehicle. The battery swapping robot 9 of this application is equipped with two bidirectional telescopic mechanisms 91. 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.

[0079] 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 mounting seats 2120 on the charging base during the battery swapping process, allowing each battery mounting seat 2120 on the charging base to maintain a full load of battery boxes, thereby increasing the battery box loading capacity of the charging compartment.

[0080] 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 charging base where the battery mounting bracket is installed 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 mounting bracket 2120.

[0081] 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 the depleted battery box into the end of the charging base, 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, so that the right gripper 92 can load the depleted battery box into the battery mounting base 2120 at the end of the charging base. Thus, it can be seen that by setting the extension guide rail 162, a fully charged battery box can be grabbed from any position on the charging base box, making it convenient to install a depleted battery box onto the battery fixing seat 2120 at the end of the charging base box.

[0082] 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.

[0083] 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.

[0084] Example 2

[0085] See Figure 2As shown, Embodiment 2 of this application provides a battery swapping device. The battery swapping device in Embodiment 2 is similar to that in Embodiment 1 in that it also includes a charging base, a guide rail 16, and a battery swapping robot 9. The charging base has multiple battery mounting seats 2120 along its length. The guide rail 16 is located on one side of the charging base along its width direction and extends along the length direction of the charging base. 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 charging base 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.

[0086] 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.

[0087] 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.

[0088] Example 3

[0089] This application provides a method for swapping the power of the power swapping equipment described in Embodiments 1 and 2 above, including:

[0090] Step S101: After the battery swapping equipment receives the battery swapping request from the battery swapping vehicle, it determines the charging position of the fully charged battery box.

[0091] 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.

[0092] Step S102: The battery swapping equipment 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.

[0093] Step S103: The battery swapping equipment 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.

[0094] The battery swapping device 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, has a length at both ends that is longer than the charging base box located within the charging compartment by one charging position. Alternatively, the charging compartment has a free space at each end with the same size as a charging position, without a battery mounting bracket 2120, and the charging compartment and the battery swapping compartment have the same length.

[0095] This embodiment of the application, after the battery swapping device determines the charging position of the fully charged battery box, further includes: the battery swapping device determining whether the arrangement mode of the first bidirectional telescopic mechanism and the second bidirectional telescopic mechanism is a separate mode or a combined mode; wherein, the separate mode means that the first bidirectional telescopic mechanism is arranged on the first battery swapping robot, and the second bidirectional telescopic mechanism is arranged on the second battery swapping robot. The combined mode means that both the first bidirectional telescopic mechanism and the second bidirectional telescopic mechanism are arranged on the third battery swapping robot.

[0096] The battery swapping device 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 battery swapping device determines that the first and second bidirectional telescopic mechanisms are configured in a split mode, it designates the battery swapping robot 9 closest to the charging position of the fully charged battery box as the first battery swapping robot, and designates the battery swapping robot 9 not closest to the charging position of the fully charged battery box 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 bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle according to the first instruction. A 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.

[0097] The process of the battery swapping equipment controlling the first bidirectional telescopic mechanism to store a fully charged battery box onto the battery swapping vehicle, and driving the second bidirectional telescopic mechanism to store a depleted battery box onto the charging position includes: the battery swapping equipment sending a third instruction to the first battery swapping robot and simultaneously sending a fourth instruction 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 instruction, and the second battery swapping robot driving the second bidirectional telescopic mechanism to store a depleted battery box according to the fourth instruction. The battery pack is placed in the charging position; or, after the first battery swapping robot drives the first bidirectional telescopic mechanism according to the third instruction to place the fully charged battery pack onto the battery swapping vehicle, the second battery swapping robot drives the second bidirectional telescopic mechanism according to the fourth instruction to place the depleted battery pack onto the charging position; or, after the second battery swapping robot drives the second bidirectional telescopic mechanism according to the fourth instruction to place the depleted battery pack onto the charging position, the first battery swapping robot drives the first bidirectional telescopic mechanism according to the third instruction to place the fully charged battery pack onto the battery swapping vehicle.

[0098] The battery swapping device 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 battery swapping device determines that the first and second bidirectional telescopic mechanisms are in 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 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.

[0099] The process of the battery swapping device controlling the first bidirectional telescopic mechanism to store a fully charged battery box onto the battery swapping vehicle and driving the second bidirectional telescopic mechanism to store a depleted battery box onto the charging position includes: the battery swapping device 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.

[0100] The battery swapping vehicle is used to send a battery swapping request to the battery swapping equipment. The battery swapping equipment is used to, upon receiving the battery swapping request from the battery swapping vehicle, determine the charging position of a fully charged battery box; drive a first bidirectional telescopic mechanism to grab a fully charged battery box located at the charging position, and drive a second bidirectional telescopic mechanism to grab a depleted battery box located on the battery swapping vehicle; drive the first bidirectional telescopic mechanism to store the grabbed fully charged battery box on the battery swapping vehicle, and drive the second bidirectional telescopic mechanism to store the grabbed depleted battery box at the charging position.

[0101] Example 4

[0102] In this embodiment, the battery swapping equipment 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.

[0103] The battery swapping method of this battery swapping equipment includes:

[0104] Step S101: After the battery swapping equipment 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.

[0105] Step S102: When the battery swapping device 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.

[0106] Step S103: When the battery swapping device 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.

[0107] 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.

[0108] 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.

[0109] The process includes, after determining the charging position of the fully charged battery box, the battery swapping equipment further includes: the battery swapping equipment detecting whether the temporary storage position for temporarily storing the depleted battery box is available; when the battery swapping equipment 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.

[0110] 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.

[0111] After the battery swapping device determines the charging position of the fully charged battery box, the embodiment of the present invention further includes: the battery swapping device determines a battery swapping robot 9 that matches the charging position of the fully charged battery box, and uses the battery swapping robot as the main battery swapping robot 9.

[0112] The battery swapping equipment, 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 normally. If the primary battery swapping robot 9 is functioning normally, it generates a first battery swapping instruction and sends it to the primary battery swapping robot 9. If the primary battery swapping robot 9 is not functioning normally, it generates a second battery swapping instruction and sends it 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.

[0113] The battery swapping equipment 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 sent to the main battery swapping robot 9 and the backup battery swapping robot 9 at the same time, so that the main 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.

[0114] Example 5

[0115] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, Embodiment 5 of this application provides the structure of the bidirectional telescopic mechanism 91 described 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 connects adjacent telescopic frames. The telescopic drive member may include a telescopic cylinder, whose telescopic movement can drive two adjacent telescopic frames to move away from or towards each other. 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] See Figure 1 and Figure 2 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.

[0122] 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.

[0123] Example 6

[0124] In one possible implementation, see Figures 4 to 12 As shown, the battery swapping equipment includes a battery swapping compartment 100, which has the aforementioned guide rail and battery swapping robot. The battery swapping compartment 100 also includes a side wall, a top wall 13, and a cover 14. The top wall 13 is connected to the side wall, and the top wall 13 and the side wall together form a cavity, within which the guide rail 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.

[0125] 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 upright, 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] The through groove can be elongated, which solves the problem of misalignment between the through groove and the fixing hole caused by manufacturing errors.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] Example 7

[0141] See Figures 13 to 19 As shown in the illustration, this application provides a more detailed description of the battery swapping compartment for a battery swapping device. The compartment includes a casing 1, a door 2, and a battery swapping robot (not shown). The casing 1 forms 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 box grasped by the gripper on the battery swapping robot. The doorway 12 on the casing 1 facilitates the bidirectional telescopic mechanism of the battery swapping robot extending out of the casing 1 to grasp or unload the battery box. The side of the battery swapping compartment facing away from the doorway is an open side, communicating with a charging compartment, which has a charging base and a battery mounting base. The charging compartment stores the battery box, and a charger is installed inside for charging the battery box. 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.

[0142] In one possible implementation, see Figure 14 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] In one possible implementation, see Figure 15 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] In one possible implementation, see Figures 17 to 19As 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.

[0159] Example 8

[0160] See Figures 20 to 25As shown in Embodiment 5 of this application, the charging compartment 200 of the battery swapping equipment is described in detail. The charging compartment 200 includes a charging base 210, an upper housing 230, and multiple chargers 220. Each battery holder 2120 is located on the top of the charging base 210. The charging base 210 has multiple lifting legs 2110 for leveling the charging base 210. Multiple battery holders 2120 are located on the top of the charging base 210. Each charger 220 is located inside the charging base 210 and is electrically connected to the battery holder 2120 to charge the battery boxes mounted on the battery holder 2120. For example, the battery holder 2120 has a charging terminal for charging the battery boxes, and the charger is directly electrically connected to this charging terminal. A power connection terminal is located at the bottom of the battery box. When the battery box is mounted on the battery holder, the charging terminal and the power connection terminal are directly electrically connected to achieve charging. The upper housing 230 is detachably connected to the charging base 210, and the upper housing 230 covers each of the battery mounting brackets 2120.

[0161] The charging compartment 200 of this application can not only temporarily store the depleted battery boxes removed from the battery swapping vehicle, but also charge the depleted battery boxes without having to be transported to other stations for charging, thus reducing transportation costs. The upper shell 230 can cover each battery mounting bracket 2120, providing protection for the battery boxes and charger 220.

[0162] In one possible implementation, see Figure 22 and Figure 23 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.

[0163] In this implementation, the top wall 231 is inclined to facilitate drainage and prevent rainwater from seeping into the charging compartment 200. The battery swapping device also has a battery swapping compartment, in which a battery swapping robot is installed. A battery swapping avoidance opening 233 (or a second battery swapping avoidance opening) 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. This avoids a large amount of rainwater entering the battery swapping device and pouring onto the battery swapping robot performing its task, thus improving safety.

[0164] In one possible implementation, see Figure 23As 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.

[0165] 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.

[0166] In one possible implementation, see Figure 22 and Figure 23 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] In one possible implementation, see Figure 23 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.

[0171] In one possible implementation, see Figure 20 and Figure 21 As shown, the charging base box 210 is provided with a guide component 2130. 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 2130 until it is supported on the charging base box 210.

[0172] In this implementation scheme, the guide component 2130 facilitates accurate assembly of the upper housing. A lifting ring can be installed on the upper housing for lifting and lowering using hoisting equipment.

[0173] In one possible implementation, the guide component 2130 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 2130 can be inserted into the guide mating hole 232.

[0174] In one possible implementation, the charging base 210 has an upper wall, and the lifting leg 2110 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.

[0175] In one possible implementation, see Figure 24 and Figure 25 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.

[0176] 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.

[0177] 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.

[0178] Multiple battery mounting brackets 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 mounting brackets via a power supply cable.

[0179] In one possible implementation, see Figure 25As 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.

[0180] 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 occupied by all the chargers 220 and exhaust pipes 215 in the battery swapping equipment is small, which helps to reduce the width of the charging base box 210.
