Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle technology, and specifically relates to a new energy battery swapping station housing structure with a three-dimensional buffer function. Background Technology

[0002] Battery swapping stations for new energy vehicles are facilities that provide rapid battery replacement services for electric vehicles. With the promotion of battery swapping as a new energy vehicle model, the efficiency, land utilization, and operational reliability of swapping stations have become key factors restricting their large-scale commercial deployment.

[0003] Currently, a Chinese invention, CN116409174B, discloses a non-lifting battery swapping station for new energy vehicles. Existing battery swapping stations typically employ a linear storage layout, where battery packs are laid flat along fixed tracks or the sides of channels, requiring swapping robots to move back and forth within these long, straight channels to access and retrieve batteries. However, this method has certain problems. Firstly, it requires a dedicated movement channel running through the entire storage area for the robot, and since this channel itself does not have storage functionality, it occupies a significant amount of core space within the station, resulting in low space utilization within the station's interior.

[0004] Secondly, when it is necessary to increase the number of batteries stored, the only way is to extend the aisle and add battery buffer racks on both sides of the aisle. This further increases the travel distance of the battery swapping robot, making the waiting time for new energy vehicles to swap batteries longer. Although the number of batteries stored can be increased by adding multi-layer shelves, storage and retrieval equipment such as stacker cranes or elevators still need to move on fixed tracks. This does not completely eliminate the problem of wasted space caused by making way for movement, which in particular affects the cost of deploying new energy battery swapping stations in urban centers and areas with high land costs. Summary of the Invention

[0005] The purpose of this invention is to provide a battery swapping station housing structure with a three-dimensional buffer function. Its advantage is that multiple battery buffer racks are arranged in a circular array on the surface of the battery swapping robot. This central radial layout can convert more space into effective battery storage locations or shared working areas. This design maximizes the number of batteries that can be densely stored per unit area, and its space utilization rate is higher than that of the linear layout of traditional battery swapping stations.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a new energy battery swapping station housing structure with a three-dimensional buffer function, comprising a battery swapping housing and a battery storage housing, wherein the bottom of the battery swapping housing and the battery storage housing are bolted to a buried housing, the buried housing has a connecting groove inside that communicates with the bottom of the battery swapping housing and the battery storage housing, the battery storage housing has a battery buffer rack bolted to its interior, the battery buffer rack is installed in a circular array inside the battery storage housing, and the buried housing has a battery swapping mechanism and a rotating mechanism that cooperate with the battery buffer rack.

[0007] The above technical solution involves arranging multiple battery buffer racks in a circular array inside the storage housing to form a multi-layered, three-dimensional storage ring. The battery swapping robot, which serves as the core of the storage and retrieval system, and its lifting and rotating drive mechanisms are located at the center of this storage ring. This center-radial layout, compared to the long, straight aisles that traditional layouts require reserving space for the battery swapping robot without storing any batteries, can convert more space into effective battery storage locations or shared working areas. When any battery pack needs to be accessed, the central rotating mechanism can drive the battery swapping robot to rotate circumferentially, directly aligning it with the target compartment. Combined with vertical lifting, the operation can be completed with the shortest and most unique path. This design maximizes the number of batteries that can be densely stored per unit area. Even if more battery buffer racks are needed, this can be achieved by increasing the ring diameter and the number of battery buffer racks in the outer ring array of the rotating mechanism. More importantly, within the same three-dimensional space, this method obviously has a higher space utilization rate than a linear arrangement, making it more suitable for battery swapping station deployment in urban centers and areas with high land costs.

[0008] The present invention is further configured such that the battery swapping mechanism includes a first motor bolted to one side of the buried housing, a first one-way coupling bolted to the output end of the first motor, a second one-way coupling rotatably connected to the buried housing at the top of the first one-way coupling, bevel gears meshing with each other fixedly sleeved at the ends of the first and second one-way couplings near the first motor, and horizontal positive and negative lead screws and a first circular gear respectively bolted to the ends of the first and second one-way couplings away from the first motor, which are rotatably connected to the buried housing. A first lead screw sleeve is threaded to the surface of the horizontal positive and negative lead screws, and a sliding tray slidably connected to the connecting groove is bolted to the top of the first lead screw sleeve.

[0009] The above technical solution involves arranging multiple battery cache racks in a circular array inside the storage box to form a multi-layered three-dimensional storage ring. This centrally radiating layout, compared to the traditional layout which requires reserving long, straight channels for battery swapping robots that do not store any batteries, can convert more space into effective battery storage locations or shared work areas.

[0010] The invention is further configured such that a rotating ring is slidably connected to the buried housing at the bottom of the connecting groove of the battery storage box, and an annular rack meshing with the first circular gear is fixedly sleeved on the surface of the rotating ring, and the rotating ring is located on the outer surface of the sliding tray.

[0011] The above technical solution involves activating a first motor to drive two bevel gears to mesh, causing them to rotate in opposite directions. Both the first and second one-way couplings can only drive the horizontal lead screw or the first circular gear to rotate counter-clockwise. Therefore, when the first motor drives the bevel gear at one end of the horizontal lead screw to rotate counter-clockwise, the bevel gear at the bottom of the first circular gear will rotate clockwise, thus not driving the first circular gear to rotate. Conversely, when the first motor drives the bevel gear at one end of the horizontal lead screw to rotate clockwise, the horizontal lead screw will not rotate, while the bevel gear at the bottom of the first circular gear will rotate counter-clockwise, thus driving the first circular gear to rotate. This allows the first motor to control the reciprocating sliding of the sliding tray and the rotation of the rotating ring by changing the direction of rotation.

[0012] The invention is further configured such that the rotating mechanism includes a support column bolted to one side of the inner wall of the rotating ring, a vertical lead screw rotatably connected inside the support column, a rotating seat welded to the top of the support column and rotatably connected to the battery storage box, a second motor bolted to one side inside the rotating seat, a second circular gear meshing with each other bolted to the output end of the second motor and the top of the vertical lead screw, the second motor being bolted to the second circular gear via a coupling, a lifting tray threaded through the side of the vertical lead screw near the sliding tray, a vertical through groove slidably connected to the lifting tray on the side of the support column near the lifting tray, a battery swapping robot slidably connected to the top of the lifting tray and used in conjunction with the battery buffer rack, and a battery pack slidably connected to the top of the battery swapping robot.

[0013] The above technical solution allows for the increase in the number of battery buffer racks when the ring diameter needs to be expanded, thereby increasing the number of battery buffer racks in the outer ring array of the rotating mechanism. This eliminates the need for a long, straight channel for the battery swapping robot to transport the battery pack, resulting in higher space utilization within the same three-dimensional space.

[0014] The present invention is further configured such that a battery cache tray is bolted inside the battery cache rack and slidably connected to the battery pack; a support plate is bolted to the side of the battery cache tray away from the battery swapping robot; a battery charger for use with the battery pack is bolted to the side of the support plate near the battery cache tray; and a composite charging cable electrically connected to the battery charger is installed through the inside of the support plate.

[0015] The above technical solution is used to connect a battery charger to a power source, thereby charging the depleted battery pack that has slid to the top of the battery buffer disk.

[0016] The present invention is further configured such that battery push rollers are rotatably connected to both sides of the battery buffer disk and the top of the battery swapping robot, and a battery remover for use with the battery pack is rotatably connected to the top of the battery swapping robot. A drive motor is installed at the bottom of the battery remover and at one end of the battery push roller. The battery push roller and the battery remover are bolted to the output end of the drive motor via a coupling.

[0017] The above technical solution is adopted: by turning on the drive motor to drive the battery remover to rotate, the battery pack on top of the battery swapping robot and the battery buffer can slide.

[0018] The invention is further configured such that inclined push plates for use with the battery swapping robot and the battery charger are welded to both sides of the top of the battery buffer disk, and visual sensors for use with the battery pack are bolted to the four corners of the top of the battery swapping robot.

[0019] The above technical solution involves installing a slanted pusher plate to limit the sliding of the battery pack as it slides to the top of the battery buffer tray, ensuring accurate alignment and insertion of the battery pack with the battery charger. Furthermore, installing a vision sensor allows for the positioning of the battery swapping robot's lifting and sliding movements, enabling the first and second motors to accurately move and replace the battery pack on top of the robot.

[0020] The invention is further configured such that a battery lifting cylinder is bolted to the bottom of the battery swapping box, the top of the battery lifting cylinder is bolted to a lifting plate via a rigid coupling, and lifting through slots that are slidably connected to the lifting plate are provided on both sides inside the sliding tray.

[0021] The above technical solution is adopted: by activating the battery lifting cylinder to drive the lifting plate, the battery swapping robot can be lifted to the bottom of the new energy vehicle, so that the battery pack can be installed and removed. At the same time, a lifting slot is opened inside the sliding tray so that the lifting plate can pass through without interfering with the use.

[0022] The present invention is further configured such that the bottom of the battery swapping robot and the top of the lifting tray are integrally formed with trapezoidal protrusions, and the bottom of the battery swapping robot and the top of the sliding tray and the lifting plate are provided with trapezoidal grooves that cooperate with the trapezoidal protrusions.

[0023] The above technical solution is adopted because the trapezoidal protrusion on the top of the lifting tray has the same sliding direction as the horizontal positive and negative screws. Therefore, the sliding tray will not interfere with the displacement when it drives the battery swapping robot to move. Similarly, the trapezoidal groove on the top of the sliding tray is opposite to the sliding tray. Therefore, when the battery swapping robot moves down to the top of the sliding tray, the trapezoidal protrusion and the trapezoidal groove can engage with each other, thereby stably driving the battery swapping robot to slide, while not affecting the lifting tray driving the battery swapping robot to move up and down.

[0024] The invention is further configured such that a sliding cylinder is bolted to the bottom of the battery swapping box, and the output end of the sliding cylinder is bolted to a sealing plate that is slidably connected to the buried box via a rigid coupling.

[0025] The above technical solution involves opening the sliding cylinder to move the sealing plate, thereby opening and closing the bottom of the battery swapping box. This prevents the bottom of the battery swapping box from being sealed when the battery is not being swapped, thus preventing garbage from entering.

[0026] In summary, the present invention has the following beneficial effects: 1. When the first motor rotates counterclockwise, it directly drives the horizontal lead screw to rotate, converting it into horizontal linear motion of the pallet. When the motor rotates clockwise, the horizontal lead screw does not rotate, but the bevel gear at the bottom of the first circular gear rotates counterclockwise through meshing, thereby driving the first circular gear to rotate. This rotation further engages with the ring rack on the rotating ring, driving the entire battery swapping robot to rotate circumferentially, thus enabling both horizontal movement and circumferential rotation of the battery swapping robot. This allows for a continuous automated battery swapping process, shortening the battery swapping time for new energy vehicles and improving the efficiency of battery swapping stations. 2. By arranging multiple battery racks in a circular array inside the storage housing, a multi-layered three-dimensional storage ring is formed, with the battery swapping robot and its lifting and rotating drive mechanism located at the center of this storage ring. This center-radial layout, compared to the long, straight channels that traditional layouts require reserving for the battery swapping robot but do not store any batteries, can convert more space into effective battery storage locations or shared working areas. When any battery pack needs to be accessed, the central rotating mechanism can drive the battery swapping robot to rotate circumferentially, directly aligning it with the target compartment, and then combining this with vertical lifting to complete the operation—the shortest and only path. This design maximizes the number of batteries that can be densely stored per unit area. Even if more battery racks are needed, this can be achieved by increasing the ring diameter and the number of battery racks in the outer ring array of the rotating mechanism. More importantly, within the same three-dimensional space, this method obviously has a higher space utilization rate than a linear arrangement, making it more suitable for battery swapping station deployment in urban centers and areas with high land costs.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1: refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10A new energy battery swapping station enclosure structure with a three-dimensional buffer function includes a battery swapping enclosure 1 and a battery storage enclosure 2. The bottoms of the battery swapping enclosure 1 and the battery storage enclosure 2 are bolted to a buried enclosure 3. The buried enclosure 3 has a connecting groove 4 that communicates with the bottoms of the battery swapping enclosure 1 and the battery storage enclosure 2. Battery buffer racks 5 are bolted to the inside of the battery storage enclosure 2. The battery buffer racks 5 are arranged in a ring array inside the battery storage enclosure 2. The buried enclosure 3 houses a battery swapping mechanism 6 and a rotating mechanism 7 that work in conjunction with the battery buffer racks 5. By arranging multiple battery buffer racks 5 in a circular array inside the storage enclosure 2, a multi-layered three-dimensional storage ring is formed, with the battery swapping robot, which serves as the storage core, and its lifting and rotating drive mechanisms located at the center of this storage ring. This centrally radiating layout, compared to the traditional layout which requires reserving long, straight channels for the battery swapping robot that do not store any batteries, can convert more space into effective battery storage locations or shared working areas. When any battery pack needs to be accessed, the central rotating mechanism 7 rotates circumferentially to directly align with the target compartment, and then combines this with vertical lifting to complete the operation, achieving the shortest and only path. This design maximizes the number of batteries that can be densely stored per unit area. Even if more battery buffer racks 5 are needed, this can be achieved by increasing the annular diameter and increasing the number of battery buffer racks 5 in the outer array of the rotating mechanism 7. More importantly, within the same three-dimensional space, this method obviously has a higher space utilization rate compared to linear arrangements, making it more suitable for the deployment of battery swapping stations in urban centers and areas with high land costs.

[0031] refer to Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 The battery swapping mechanism 6 includes a first motor 601 bolted to one side inside the buried housing 3. The output end of the first motor 601 is bolted to a first one-way coupling 603. A second one-way coupling 604 rotatably connected to the buried housing 3 is provided on the top of the first one-way coupling 603. The ends of the first one-way coupling 603 and the second one-way coupling 604 near the first motor 601 are both fixedly fitted with meshing bevel gears 605. The ends of the first one-way coupling 603 and the second one-way coupling 604 away from the first motor 601 are respectively bolted to a horizontal positive and negative lead screw 606 and a first circular gear 609 rotatably connected to the buried housing 3. The surface of the horizontal positive and negative lead screw 606 is threaded with a first lead screw sleeve 610. The top of the first lead screw sleeve 610 is bolted to a sliding tray 602 slidably connected to the connecting groove 4. The buried box 3 is installed at the bottom of the battery swapping box 1 and the battery storage box 2. It can be accessed through the internal channels of the battery swapping box 1 and the battery storage box 2 to perform maintenance and repair on the internal parts.

[0032] refer to Figure 2 , Figure 3 , Figure 4 The connecting groove 4 is located at the bottom of the inner cavity of the battery storage box 2, and a rotating ring 607 is slidably connected to the buried box 3. A ring rack 608 that meshes with the first circular gear 609 is fixedly sleeved on the surface of the rotating ring 607. The rotating ring 607 is located on the outer surface of the sliding tray 602. By turning on the first motor 601, the two bevel gears 605 are driven to mesh with each other, causing the two bevel gears 605 to rotate in opposite directions; while the first one-way coupling 603 and the second one-way coupling 604 can only drive the horizontal forward and reverse lead screw 606 or the first circular gear 609 to rotate in a counterclockwise direction. Therefore, when the first motor 601 drives the bevel gear 605 at one end of the horizontal lead screw 606 to rotate counterclockwise, the bevel gear 605 at the bottom of the first circular gear 609 will rotate clockwise, thus not driving the first circular gear 609 to rotate; conversely, when the first motor 601 drives the bevel gear 605 at one end of the horizontal lead screw 606 to rotate clockwise, the horizontal lead screw 606 will not rotate, while the bevel gear 605 at the bottom of the first circular gear 609 will rotate counterclockwise, thereby driving the first circular gear 609 to rotate, so that the first motor 601 can control the reciprocating sliding of the sliding tray 602 and the rotating ring 607 respectively by changing the direction of rotation.

[0033] refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 10 The rotating mechanism 7 includes a support column 701 bolted to one side of the inner wall of the rotating ring 607. A vertical lead screw 702 is rotatably connected inside the support column 701. A rotating seat 703, which is rotatably connected to the battery storage box 2, is welded to the top of the support column 701. A second motor 704 is bolted to one side inside the rotating seat 703. A second circular gear 705 that meshes with each other is bolted to the output end of the second motor 704 and the top of the vertical lead screw 702. The second motor 704 is bolted to the second circular gear 705 through a coupling. A lifting tray 706 is threaded through the side of the vertical lead screw 702 near the sliding tray 602. A vertical through groove that is slidably connected to the lifting tray 706 is opened on the side of the support column 701 near the lifting tray 706. A battery swapping robot 707 that works with the battery buffer rack 5 is slidably connected to the top of the lifting tray 706. A battery pack 8 is slidably connected to the top of the battery swapping robot 707.

[0034] refer to Figure 5 , Figure 9The battery buffer rack 5 is internally bolted to a battery buffer tray 9 that is slidably connected to the battery pack 8. A support plate 10 is bolted to the side of the battery buffer tray 9 furthest from the battery swapping robot 707. A battery charger 11, which works with the battery pack 8, is bolted to the side of the support plate 10 closest to the battery buffer tray 9. A composite charging cable 24, electrically connected to the battery charger 11, is installed through the support plate 10. This cable connects the battery charger 11 to a power source, thereby charging the depleted battery pack that has slid to the top of the battery buffer tray 9. The composite charging cable 24 contains not only a charging cable connected to the power bus but also a data cable for connecting to the BMS system, allowing the battery charger 11 to rationally control charging based on battery status via the BMS system.

[0035] refer to Figure 5 , Figure 9 , Figure 10 , Figure 11 , Figure 12 Battery push rollers 12 are rotatably connected to both sides of the top of the battery buffer tray 9 and the battery swapping robot 707. A battery remover 13, which works in conjunction with the battery pack 8, is rotatably connected to the top of the battery swapping robot 707. A drive motor 14 is installed at the bottom of the battery remover 13 and at one end of the battery push roller 12. The battery push roller 12 and the battery remover 13 are bolted to the output end of the drive motor 14 via a coupling. By turning on the drive motor 14, the battery push roller 12 and the battery remover 13 are rotated respectively, allowing the battery swapping robot 707 and the battery pack 8 on top of the battery buffer tray 9 to slide. The position of the battery remover 13 can be customized according to the bolt position of the battery pack on the battery swapping robot 707. Its hexagonal end can be inserted into the internal hexagonal bolt, so that the bolt can be removed and installed during rotation.

[0036] refer to Figure 5 , Figure 9 , Figure 10 Both sides of the top of the battery buffer tray 9 are welded with inclined push plates 23 for use with the battery swapping robot 707 and the battery charger 11. Vision sensors 15 for use with the battery pack 8 are bolted to the four corners of the top of the battery swapping robot 707. The inclined push plates 23 limit the sliding of the battery pack 8 when it slides to the top of the battery buffer tray 9, ensuring accurate alignment and insertion of the battery pack 8 with the battery charger 11. The vision sensors 15 position the lifting and sliding of the battery swapping robot 707, enabling the first motor 601 and the second motor 704 to accurately move and replace the battery pack 8 on top of the battery swapping robot 707.

[0037] refer to Figure 3 , Figure 8 , Figure 13The inner cavity of the connecting groove 4 is bolted to the bottom of the battery swapping box 1 and is connected to a battery lifting cylinder 20. The top of the battery lifting cylinder 20 is bolted to a lifting plate 19 via a rigid coupling. Both sides of the sliding tray 602 have lifting slots 18 that are slidably connected to the lifting plate 19. By activating the battery lifting cylinder 20, the lifting plate 19 can be driven to lift the battery swapping robot 707 to the bottom of the new energy vehicle, thereby enabling the installation and removal of the battery pack. At the same time, the lifting slots 18 inside the sliding tray 602 allow the lifting plate 19 to pass through without interfering with its use.

[0038] refer to Figure 7 , Figure 8 , Figure 10 , Figure 13 The bottom of the battery swapping robot 707 and the top of the lifting tray 706 are both integrally formed with trapezoidal protrusions 16. The bottom of the battery swapping robot 707 and the top of the sliding tray 602 and the lifting plate 19 are all provided with trapezoidal grooves 17 that cooperate with the trapezoidal protrusions 16. Since the trapezoidal protrusions 16 on the top of the lifting tray 706 slide in the same direction as the horizontal positive and negative lead screws 606, the movement of the battery swapping robot 707 driven by the sliding tray 602 will not interfere with the displacement. Similarly, the trapezoidal grooves 17 on the top of the sliding tray 602 move in the opposite direction to the movement of the sliding tray 602. Therefore, when the battery swapping robot 707 moves downward to the top of the sliding tray 602, the trapezoidal protrusions 16 and the trapezoidal grooves 17 can engage with each other, thereby stably driving the battery swapping robot 707 to slide, while not affecting the up and down movement of the battery swapping robot 707 driven by the lifting tray 706.

[0039] refer to Figure 2 , Figure 3 , Figure 14 The inner cavity of the connecting groove 4 is bolted to the bottom of the battery swapping box 1, and a sliding cylinder 22 is bolted thereto. The output end of the sliding cylinder 22 is bolted to a sealing plate 21 that is slidably connected to the buried box 3 via a rigid coupling. By opening the sliding cylinder 22, the sealing plate 21 can be slid, thereby opening and closing the bottom of the battery swapping box 1, thus preventing the bottom of the battery swapping box 1 from being sealed when the battery is not being changed, and preventing garbage from entering.

[0040] Brief description of the usage process: First, the new energy vehicle is parked inside the battery swapping box 1, and the sealing plate 21 is opened by activating the sliding cylinder 22. Then, the first motor 601 is activated to drive the first one-way coupling 603 to rotate clockwise. Since the activation of the first motor 601 drives the two bevel gears 605 to mesh with each other, the two bevel gears 605 rotate in opposite directions; while the first one-way coupling 603 and the second one-way coupling 604 can only drive the horizontal forward and reverse lead screw 606 or the first circular gear 609 to rotate counterclockwise. Therefore, when the first motor 601 drives the bevel gear 605 at one end of the horizontal positive and negative lead screw 606 to rotate counterclockwise, the bevel gear 605 at the bottom of the first circular gear 609 will rotate clockwise (the direction of rotation is referenced to the meshing surface of the two bevel gears 605), thus not driving the first circular gear 609 to rotate; and through the thread engagement between the horizontal positive and negative lead screw 606 and the first lead screw sleeve 610, the battery swapping robot 707 on the top of the sliding tray 602 is driven to slide into the inside of the battery swapping box 1 by interlocking the trapezoidal protrusion 16 and the trapezoidal groove 17.

[0041] Then, by activating the battery lifting cylinder 20, the lifting plate 19 is pushed upwards, allowing it to pass through the lifting slot 18. This causes the battery swapping robot 707 on top of the sliding tray 602 to attach to the battery pack 8 at the bottom of the new energy vehicle. The drive motor 14 is then activated to rotate the battery remover 13, causing it to tighten the bolts around the battery pack 8, allowing the depleted battery pack 8 to be removed from the bottom of the new energy vehicle and onto the battery swapping robot 707. Next, the battery lifting cylinder 20 is activated to move the lifting plate 19 downwards and reset it. The first motor 601 is then activated again to rotate clockwise, causing the horizontal lead screw 606 to engage with the first lead screw sleeve 610. This engages the lead screw 606, causing the battery swapping robot 707 on top of the sliding tray 602 to slide and reset inside the connecting slot 4. The battery pack on top of the battery swapping robot 707 is then moved inside the battery storage box 2, at which point the lifting tray 706 is positioned on top of the sliding tray 602. The second motor 704 is activated to drive the second circular gear 705 to rotate and mesh, which in turn drives the vertical lead screw 702 to rotate inside the support column 701. This allows the lifting tray 706, which is located on top of the sliding tray 602, to move the battery swapping robot 707 upward under the threaded engagement of the second lead screw sleeve and the vertical lead screw 702. This allows the battery pack 8 on top of the battery swapping robot 707 to move to the top of the battery buffer tray 9, where there is still space. The drive motor 14 is activated to drive the battery push roller 12 to rotate, sliding the battery pack 8 to the top of the battery buffer tray 9. This aligns the charging interface of the battery pack 8 and allows it to slide into the battery charger 11 for automatic charging. At the same time, the fully charged battery pack 8 on top of the battery buffer tray 9 can also be slid to the top of the battery swapping robot 707 by the drive motor 14 driving the battery push roller 12.

[0042] If the fully charged battery pack 8 is on the other side, when the first motor 601 drives the bevel gear 605 at one end of the horizontal forward and reverse lead screw 606 to rotate clockwise, the horizontal forward and reverse lead screw 606 will not rotate, while the bevel gear 605 at the bottom of the first circular gear 609 will rotate counterclockwise. This will cause the top first circular gear 609 to mesh with the ring rack 608, thereby causing the rotating ring 607 to rotate. This allows the lifting tray 706 to engage with the trapezoidal protrusion 16 and trapezoidal groove 17, causing the battery swapping robot 707 to rotate directly inside the battery storage box 2, rotating the battery swapping robot 707 onto the battery buffer rack 5 in different positions (see...). Figure 10 The battery pack 8 can slide out from one end of the battery swapping robot 707 after rotation, with a larger opening that will not cause jamming, to the battery buffer rack 5 in different positions, so that the fully charged battery pack 8 on the top of the battery buffer tray 9 can be pushed onto the battery swapping robot 707.

[0043] Finally, by activating the second motor 704 to rotate the vertical lead screw 702, the lifting tray 706 can slide downwards and reset. Simultaneously, the first motor 601 is activated to rotate clockwise, causing the two bevel gears 605 to mesh. The bevel gear 605 at the bottom of the first circular gear 609 then meshes with the ring rack 608, rotating the support column 701 and resetting the battery swapping robot 707. After moving downwards, the battery swapping robot 707 can stop on top of the sliding tray 602, where the trapezoidal protrusion 16 and trapezoidal groove 17 are engaged. At this point, the first motor 601 is activated again to rotate counterclockwise, causing the horizontal forward and reverse lead screw 606 to engage with the first lead screw sleeve 610, moving the fully charged battery pack 8 from the top of the battery swapping robot 707 into the battery swapping box 1. The battery lifting cylinder 20 then lifts the battery swapping robot 707 to the bottom of the new energy vehicle, allowing the fully charged battery pack 8 to be re-bolted to the bottom of the vehicle.

[0044] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
