Description

Technical Field

[0001] This invention relates to the field of vehicle battery swapping, and particularly to a battery mounting assembly and a battery swapping shuttle vehicle including the assembly. Background Technology

[0002] To accommodate heavier and more varied batteries, current battery swapping shuttles employ multi-layer reinforcement to increase the thickness of the battery-supporting structure. This results in the shuttle being quite thick in the height direction, severely limiting the thickness of the batteries it can support or the chassis height of the vehicle to be swapped. Furthermore, current battery swapping shuttles use multiple guiding structures to guide the battery-supporting device and the vehicle positioning device, making the structure complex. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the existing battery swapping shuttle vehicle, which has a non-compact structure, is thick and occupies a large area in the height direction, and has a complex guide structure, and to provide a battery installation component and a battery swapping shuttle vehicle containing the component.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A battery mounting assembly is disposed on a battery swapping shuttle vehicle. The battery mounting assembly includes a base and further includes:

[0006] A battery mounting plate, which is used to support the battery and can reciprocate along the unlocking direction;

[0007] A vehicle positioning plate, which is used for positioning and connecting with the vehicle to be swapped, and can reciprocate along the unlocking / unlocking direction;

[0008] The guidance module includes:

[0009] A guide rail extending along the unlocking / unlocking direction;

[0010] Two first sliders and two second sliders are disposed on the guide rail. The first sliders are connected to the battery fixing plate, and the second sliders are connected to the vehicle body positioning plate. Along the unlocking direction, the two first sliders are respectively disposed on the front and rear sides of the two second sliders.

[0011] The battery mounting assembly's guide module uses different sliders on a single guide rail to guide the vehicle body positioning plate and the battery fixing plate respectively, effectively reducing the number of guide rails in the guide module, saving space, and simplifying the structure.

[0012] The base simultaneously supports both the battery mounting plate and the vehicle positioning plate, resulting in a more compact overall battery mounting assembly structure. Both the two first sliders and two second sliders are located on guide rails, ensuring stable guidance for both the battery mounting plate and the vehicle positioning plate. The slider's positional arrangement ensures uninterrupted stroke.

[0013] Preferably, the battery mounting assembly further includes:

[0014] A first moving module is disposed on the base and is connected to and drives the battery fixing plate to reciprocate along the unlocking direction;

[0015] The second moving module is disposed on the base and is connected to and drives the vehicle positioning plate to reciprocate along the unlocking / unlocking direction;

[0016] The battery fixing plate is connected to the drive end of the corresponding first moving module via a first connector along a direction perpendicular to the unlocking / unlocking direction.

[0017] The vehicle positioning plate is arranged parallel to the bottom of the battery fixing plate, and an avoidance groove is provided on the vehicle positioning plate, through which the first connector passes.

[0018] The vehicle positioning plate is arranged parallel to the battery fixing plate below it, and a clearance groove is provided on the vehicle positioning plate to avoid the first connecting piece, so that the horizontal position relationship between the vehicle positioning plate and the battery fixing plate above it is more compact.

[0019] Preferably, the vehicle positioning plate is connected to the drive end of the corresponding second moving module via a second connector, and the second connector is respectively disposed on one side of the avoidance groove along the unlocking direction perpendicular to the unlocking direction.

[0020] By placing the second connector on the side of the vehicle positioning plate with the avoidance groove, the first connector and the second connector are distributed on the same side of the battery mounting assembly, so as to facilitate the installation arrangement of the first moving module and the second moving module relative to the base plate.

[0021] Preferably, the battery mounting assembly further includes:

[0022] Two first moving modules are disposed on the base and are jointly connected to and drive the battery fixing plate to reciprocate along the unlocking direction;

[0023] Two second moving modules are disposed on the base and are jointly connected to and drive the vehicle body positioning plate to reciprocate along the unlocking / unlocking direction;

[0024] Along a direction perpendicular to the unlocking / unlocking direction, the two first moving modules are arranged parallel to each other on the outer sides of the two second moving modules.

[0025] The first and second moving modules, which drive the battery fixing plate and the vehicle positioning plate on the base, are arranged relatively parallel to each other along the unlocking direction. The two first moving modules are arranged on the outside and the two second moving modules are arranged on the inside. This makes the connection structure of the base relative to the battery fixing plate and the vehicle positioning plate more compact, optimizes the position layout of the moving modules, and also avoids mutual interference between the battery fixing plate and the vehicle positioning plate during translation.

[0026] Preferably, the battery fixing plate is rectangular in shape, and a battery positioning part is provided in the center of the battery fixing plate. The battery fixing plate is connected to the driving end of the corresponding first moving module on both sides of the battery positioning part along the unlocking direction perpendicular to the unlocking direction through two first connectors.

[0027] The battery mounting assembly has a rectangular battery mounting plate, which improves the structural strength of the battery mounting plate while maintaining a thin overall thickness, thus meeting the design requirements of the battery mounting assembly in terms of compact structure and reduced height.

[0028] Meanwhile, by setting a battery positioning part in the center of the battery fixing plate and connecting the battery fixing plate to the first moving module on both sides of the battery positioning part, the driving force of the first moving module to drive the battery positioning part to move can be effectively transmitted to the battery through the battery positioning part, which helps the battery mounting assembly to carry the battery to move smoothly and reliably.

[0029] Preferably, there are three battery positioning parts, the distance between the first connector and the battery positioning parts located on the outer side and the battery positioning parts located in the center is 1:3, and the relative positions of each battery positioning part and the first connector are in a straight line relationship.

[0030] Preferably, the vehicle positioning plate is arranged parallel to the bottom of the battery fixing plate, and two clearance grooves are provided at the edge of the battery fixing plate, through which the two first connecting members pass respectively.

[0031] By setting a clearance groove on the vehicle positioning plate to avoid the first connector, the collision between the first connector and the vehicle positioning plate is avoided during the movement of the battery fixing plate.

[0032] Preferably, the vehicle positioning plate is connected to the drive end of the corresponding second moving module via two second connectors;

[0033] Along the direction perpendicular to the unlocking / unlocking direction, the two second connectors are respectively disposed on the inner side of the two clearance grooves.

[0034] The structural design scheme has a more compact layout.

[0035] Preferably, the vehicle positioning plate is provided with a vehicle positioning part, and the vehicle positioning plate is positioned and connected to the vehicle to be swapped through the vehicle positioning part. The vehicle positioning plate is located below the battery fixing plate, and the base is located below the vehicle positioning plate.

[0036] By setting a body positioning part on the body positioning plate to be positioned and connected with the vehicle to be swapped, the positioning effect of the body positioning plate relative to the vehicle to be swapped can be improved.

[0037] Meanwhile, the vehicle positioning plate and the battery mounting plate are staggered in the height direction, allowing them to overlap, thereby reducing the space occupied by the entire battery mounting assembly and making the battery mounting assembly more compact.

[0038] Preferably, the first slider is connected to the battery mounting plate via a pad.

[0039] By placing a pad between the first slider and the battery mounting plate, the height of the battery mounting plate relative to the guide rail is increased, thus offsetting the battery mounting plate and the vehicle positioning plate in the height direction and avoiding interference in height.

[0040] Preferably, the vehicle positioning plate is a flat plate, and the vehicle positioning plate is connected to the drive end of the corresponding second moving module on one side of the flat plate through two second connectors.

[0041] By setting a second connector on one side of the vehicle positioning plate and connecting it to the second moving module, the two second moving modules can output driving force evenly, so that the vehicle positioning plate can move stably and ensure that the battery swapping process is carried out smoothly.

[0042] Preferably, the vehicle positioning plate is trapezoidal, and the vehicle positioning part is disposed on the short side of the vehicle positioning plate along the unlocking direction. At least one end of the short side of the vehicle positioning plate has a clearance space, which is used to avoid the first slider of the two first sliders of the guide module that is closer to the vehicle positioning part.

[0043] The vehicle positioning plate adopts a trapezoidal structure design, which can withstand high loads and is structurally reliable. The drive end connected to the second moving module and the vehicle positioning part are set on both sides of the vehicle positioning plate, which can avoid interference between the vehicle positioning part and the battery fixing plate. At least one end of the short side of the vehicle positioning plate has a clearance space, which can avoid the first slider close to the vehicle positioning part when the vehicle positioning plate moves, preventing the movement of the vehicle positioning plate and the first slider from interfering with each other.

[0044] Preferably, there are two guide modules, located outside the two first moving modules along a direction perpendicular to the unlocking / unlocking direction; there are two clearance spaces at both ends of the short side of the vehicle body positioning plate, the clearance spaces being used to avoid the first slider in each group of guide modules that is close to the vehicle body positioning part.

[0045] The above structural setup allows for a more compact layout of components.

[0046] Preferably, the battery mounting assembly further includes:

[0047] The battery holder has two trays distributed above and on both sides of the battery fixing plate along the unlocking direction. A plurality of elastic elements are disposed between the trays and the battery fixing plate. The battery fixing plate carries the battery through the trays. The surface of the tray has clearance holes through which the battery positioning part passes. The elastic elements are evenly distributed along the periphery of the tray.

[0048] The above structural design effectively supports the battery and uses elastic elements to cushion the impact along the height direction during transportation. Furthermore, by increasing the number and evenly distributing the elastic elements, the battery mounting plate provides multi-point support to the pallet, ensuring that the battery weight is evenly transferred to the surface of the mounting plate.

[0049] By providing clearance holes on the surface of the tray, the tray and the battery positioning part can be arranged to overlap on the battery fixing plate, resulting in a more compact structure.

[0050] A battery swapping shuttle includes a battery mounting assembly as described above. The battery swapping shuttle also includes a shuttle frame, a traveling mechanism disposed on the shuttle frame, and a lifting mechanism. The lifting mechanism is connected to and drives the battery mounting assembly to lift and lower.

[0051] The battery installation components of this battery swapping shuttle have a more compact structure and a smaller overall height, which can reduce the overall height of the shuttle and leave more height space for batteries or vehicle chassis, so as to meet the battery swapping needs of different vehicle models.

[0052] Preferably, the lifting mechanism has a lifting guide, which guides the object by means of a scissor lift.

[0053] By using a scissor lift to guide the lifting mechanism, there is no need to arrange lifting guide rails in the vertical direction, thus further reducing the space occupied by components in the height direction.

[0054] Preferably, the shuttle frame includes a frame module formed by two opposing crossbeams and two opposing longitudinal beams. The frame module also includes two partition plates parallel to the longitudinal beams and connected to the crossbeams, arranged along the length of the frame module. The partition plates divide the frame module into a middle area and side areas symmetrically arranged on both sides of the middle area.

[0055] The walking mechanism includes multiple drive wheel sets arranged sequentially along the travel direction of the battery swapping shuttle. Each side area has at least two drive wheel sets, and each drive wheel set can be driven independently.

[0056] By setting at least two drive wheel sets in each side area of ​​the frame module, and by controlling the travel speed of each drive wheel set separately, the battery swapping shuttle can move in multiple directions, making it easy to adjust the attitude of the battery swapping shuttle relative to the vehicle, so that the battery swapping work can be completed even when the vehicle is parked crookedly.

[0057] The positive and progressive effects of this invention are as follows:

[0058] In the battery mounting assembly and the battery swapping shuttle containing it, the guiding module of the battery mounting assembly uses different sliders on a single guide rail to guide the vehicle body positioning plate and the battery fixing plate respectively. This effectively reduces the number of guide rails in the guiding module, saves space, and further meets the design requirements of the battery mounting assembly in terms of compact structure and reduced assembly height. The simplified structure using a single guide rail ensures stable guidance for both the battery fixing plate and the vehicle body positioning plate, and the positional layout of the sliders ensures that the travel of the battery fixing plate and the vehicle body positioning plate is not disturbed. The base simultaneously supports both the battery fixing plate and the vehicle body positioning plate, making the overall structure of the battery mounting assembly more compact.

[0092] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0093] like Figure 1 As shown, the present invention provides a battery swapping shuttle 100, which specifically includes a shuttle frame 20 and a battery mounting assembly 10, a traveling mechanism 30, and a lifting mechanism 40 disposed on the shuttle frame 20. The traveling mechanism 30 is used to drive the shuttle frame 20 to move horizontally. The two ends of the lifting mechanism 40 are respectively connected to the shuttle frame 20 and the battery mounting assembly 10. The lifting mechanism 40 rises, driving the battery mounting assembly 10 to rise and fall. The battery mounting assembly 10 is used to carry the battery. During the process of the lifting mechanism 40 driving it to rise, the battery is installed at the bottom of the vehicle to be swapped, so as to achieve the purpose of swapping the battery relative to the vehicle.

[0094] The specific structure of the battery mounting assembly 10 is as follows: Figure 2-9 As shown, it includes a base 1, a battery mounting plate 2, a vehicle body positioning plate 3, and a guide module 4. The battery mounting plate 2 carries the battery and can move back and forth along the unlocking direction A to connect or disconnect the battery from the corresponding structure of the vehicle chassis. The vehicle body positioning plate 3 positions and connects to the chassis of the vehicle to be swapped, ensuring smooth insertion of the battery mounting assembly 10 relative to the chassis. The positioning plate 3 can also move back and forth along the unlocking direction A to adjust its horizontal position relative to the chassis, ensuring successful positioning and connection.

[0095] In this embodiment, the guide module 4 specifically includes a guide rail 41 extending along the unlocking / unlocking direction A, and two first sliders 42 and two second sliders 43 disposed on the guide rail 41. The first sliders 42 and the second sliders 43 slide on the guide rail 41 respectively. The first sliders 42 are connected to the battery fixing plate 2, and the second sliders 43 are connected to the vehicle body positioning plate 3. Figure 3As shown, along the unlocking direction A, the two first sliders 42 are respectively located on the front and rear sides of the two second sliders 43, that is, the two second sliders 43 are on the inner side, while the two first sliders 42 are on the outer side.

[0096] The guide module 4 of the battery mounting assembly 10 uses different sliders on a single guide rail 41 to guide the vehicle positioning plate 3 and the battery fixing plate 2 respectively, effectively reducing the number of guide rails 41 in the guide module 4, saving space, and further meeting the design requirements of the battery mounting assembly 10 in terms of compact structure and reduced assembly height.

[0097] By having the base 1 simultaneously support the battery mounting plate 2 and the vehicle positioning plate 3, the overall battery mounting assembly 10 has a more compact structure.

[0098] like Figure 3 As shown, the battery mounting assembly 10 also includes a first moving module 5 and a second moving module 6 respectively disposed on the base 1. The first moving module 5 is used to connect and drive the battery fixing plate 2 to reciprocate along the unlocking direction A, while the second moving module 6 is used to connect and drive the vehicle body positioning plate 3 to reciprocate along the unlocking direction A. There are two guide modules 4, which are arranged perpendicular to the unlocking direction A, on the outside of the two first moving modules 5 to achieve a compact layout of the components on the base 1.

[0099] In this embodiment, both the first moving module 5 and the second moving module 6 consist of a motor, a lead screw, and a nut. The motor's drive shaft is connected to the lead screw to drive its rotation. The motor's threads engage with the lead screw's surface threads, causing the nut to reciprocate along the unlocking direction A during the lead screw's rotation. A connecting structure is provided on the nut's surface to serve as the drive end of the first moving module 5, connecting it to the battery mounting plate 2. The driving force generated by the lead screw and nut is greater than the torque in other driving directions, meeting the slow-speed, high-torque requirements of battery movement. Simultaneously, the lead screw and nut are self-locking to prevent unexpected situations.

[0100] Of course, to achieve the purpose of reciprocating movement along the unlocking / unlocking direction A, the first moving module 5 and the second moving module 6 can also adopt structures similar to those found in other existing technologies, such as cylinders and linear motors. Furthermore, using the same drive structure to achieve reciprocating movement along the unlocking / unlocking direction A also facilitates structural design, parts procurement, and installation and maintenance.

[0101] In this embodiment, as Figure 4 and Figure 5As shown, a battery positioning part 21 is provided on the battery fixing plate 2 for docking with the battery. In this embodiment, there are three battery positioning parts 21, one of which is located in the center of the battery fixing plate 2, and the other two are located on both sides of the central battery positioning part 21, perpendicular to the unlocking direction A. Figure 5 As shown, along the direction perpendicular to the unlocking / unlocking direction A, the battery positioning part 21 located in the center is provided with first connectors 22 on both sides, and the battery fixing plate 2 is connected to the driving end of the corresponding first moving module 5 through the first connectors 22.

[0102] By simultaneously positioning the battery with three battery positioning parts 21, the battery cannot be translated or rotated relative to the battery fixing plate 2 through multi-point positioning, thus improving the positioning capability of the battery fixing plate 2. Of course, in other embodiments, two or more battery positioning parts 21 can also be used to position the battery to achieve the same purpose of limiting the position of the battery relative to the battery fixing plate 2, so that the battery cannot move horizontally or rotate after being supported on the battery fixing plate 2.

[0103] In this embodiment, the battery positioning part 21 is a vertically upward extending positioning pin. By inserting the positioning pin into the pin hole at the bottom of the battery, the battery cannot move horizontally relative to the battery positioning plate. Positioning by inserting the positioning pin into the pin hole at the bottom of the battery is simple and reliable, and can meet the reliable positioning requirements of batteries with large weights.

[0104] More preferably, in this embodiment, such as Figure 4 and Figure 5 As shown, the three battery positioning parts 21 on the battery fixing plate 2 and the two first connecting parts 22 located below the battery fixing plate 2 are arranged in a straight line. By arranging the two battery positioning parts 21 other than the central one to correspond to the driving end of the first moving module 5, the horizontal driving force generated by the first moving module 5 is reliably transmitted to the battery, thereby better driving the battery to move.

[0105] Meanwhile, to balance the force relationship between each battery positioning part 21 and the first connecting member 22, the distance between the first connecting member 22 and the battery positioning part 21 located on the outer side and the battery positioning part 21 located in the center is 1:3. That is, as Figure 4 As shown, the horizontal distance between the first connector 22 and the outer battery positioning part 21 is L1, and the horizontal distance between the first connector 22 and the central battery positioning part 21 is L2, with a ratio of L1:L2 of 1:3. This spacing effectively balances the driving force generated by the first moving module 5 corresponding to each first connector 22, thus balancing the forces at each battery positioning part 21.

[0106] like Figure 6 and Figure 7 As shown, the vehicle positioning plate 3 is arranged parallel to the bottom of the battery fixing plate 2. A clearance groove 31 is provided on the vehicle positioning plate 3 so that the first connecting piece 22 located on the battery fixing plate 2 can pass downwards through the clearance groove 31 and connect with the driving end of the corresponding first moving module 5. Figure 8 As shown, by providing an avoidance groove 31 on the vehicle positioning plate 3, the horizontal position relationship between the vehicle positioning plate 3 and the battery fixing plate 2 located above it is made more compact.

[0107] from Figure 6 and Figure 8 As can be seen, a second connector 32 is provided on the lower surface of the vehicle positioning plate 3. The vehicle positioning plate 3 is connected to the drive end of the corresponding second moving module 6 through the second connector 32. Furthermore, along a direction perpendicular to the unlocking / unlocking direction A, the two second connectors 32 are arranged on one side of the two clearance grooves 31, i.e., the two clearance grooves 31 are located on the inner side, and the two second connectors 32 are located on the outer side. By respectively setting the second connectors 32 on the same side of the vehicle positioning plate 3 where the two clearance grooves 31 are located, the first connector 22 and the second connector 32 are distributed on the same side of the battery mounting assembly 10, facilitating the mounting arrangement of the first moving module 5 and the second moving module 6 relative to the base plate.

[0108] In this embodiment, as Figure 3 As shown, the base 1 is provided with two first moving modules 5 and two second moving modules 6. The two first moving modules 5 are arranged parallel to each other on the outer sides of the two second moving modules 6 along a direction perpendicular to the unlocking / unlocking direction A. By arranging the first moving modules 5 and the second moving modules 6 on the base 1, which drive the battery fixing plate 2 and the vehicle positioning plate 3, parallel to each other along the unlocking / unlocking direction A, with the two first moving modules 5 on the outer sides and the two second moving modules 6 on the inner sides, the connection structure of the base 1 relative to the battery fixing plate 2 and the vehicle positioning plate 3 becomes more compact, and the mutual interference between the battery fixing plate 2 and the vehicle positioning plate 3 during translation is also avoided.

[0109] In this embodiment, as Figure 4 and Figure 5 As shown, the battery fixing plate 2 is rectangular in shape, with a battery positioning part 21 located at the center of the rectangle. On both sides perpendicular to the unlocking direction A, the battery fixing plate 2 is connected to the driving end of the corresponding first moving module 5 via two first connectors 22. By making the battery fixing plate 2 rectangular, the structural strength of the battery fixing plate 2 can be improved while maintaining a thin overall thickness, thus meeting the design requirements of the battery mounting assembly 10 in terms of compact structure and reduced height.

[0110] Meanwhile, by setting a battery positioning part 21 at the center of the battery fixing plate 2 and connecting the battery fixing plate 2 to the first moving module 5 on both sides of the battery positioning part 21, the driving force of the first moving module 5 to drive the battery positioning part 21 to move can be effectively transmitted to the battery through the battery positioning part 21, which helps the battery mounting assembly 10 to carry the battery to move smoothly and reliably.

[0111] like Figure 8 As shown, the vehicle positioning plate 3 is arranged parallel to the bottom of the battery fixing plate 2. By setting two avoidance grooves 31 at the edge of the battery fixing plate 2, the corresponding first connector 22 is avoided, thereby preventing the first connector 22 from colliding with the vehicle positioning plate 3 during the movement of the battery fixing plate 2.

[0112] In addition, in this embodiment, the vehicle positioning plate 3 is connected to the driving ends of the corresponding two second moving modules 6 via two second connecting members 32. Furthermore, in a direction perpendicular to the unlocking / unlocking direction A, these two second connecting members 32 are respectively disposed inside the two clearance grooves 31. This structural layout allows for a more compact structure for the vehicle positioning plate 3.

[0113] like Figure 6 and Figure 7 As shown, a vehicle positioning part 33 is provided on the vehicle positioning plate 3. The vehicle positioning plate 3 is positioned and connected to the vehicle to be swapped through its vehicle positioning part 33. By providing a vehicle positioning part 33 on the vehicle positioning plate 3 for positioning and connection with the vehicle to be swapped, the positioning effect of the vehicle positioning plate 3 relative to the vehicle to be swapped can be improved. In this embodiment, there are two vehicle positioning parts 33.

[0114] With the above structural arrangement, the vehicle positioning plate 3 can be located below the battery fixing plate 2, and the base 1 can be located below the vehicle positioning plate 3. By offsetting the vehicle positioning plate 3 and the battery fixing plate 2 in the height direction, the vehicle positioning plate 3 and the battery fixing plate 2 can overlap, thereby reducing the space occupied by the entire battery mounting assembly 10 and making the battery mounting assembly 10 more compact.

[0115] In this embodiment, the vehicle positioning part 33 also uses a vertically extending positioning pin to achieve the positioning purpose. By inserting the positioning pin into the pin hole at the bottom of the vehicle, the vehicle cannot move horizontally relative to the vehicle positioning plate 3 during the battery swapping process. Positioning by inserting the positioning pin into the pin hole at the bottom of the vehicle is simple and reliable. Furthermore, the vehicle positioning part 33 and the battery fixing part use positioning pins of the same external dimensions and specifications, which facilitates structural design and mass production of parts.

[0116] In this embodiment, the battery fixing plate 2 is stacked relative to the vehicle positioning plate 3, meaning the battery fixing plate 2 is located above the vehicle positioning plate 3. Therefore, the first slider 42 needs to be raised using the pad 43 to increase the height of the battery fixing plate 2 relative to the guide rail 41, allowing the battery fixing plate 2 and the vehicle positioning plate 3 to be staggered in the height direction, thus achieving the purpose of connecting to the battery fixing plate 2. Of course, in other embodiments, a first slider 42 with a higher height can also be used to connect to the battery fixing plate 2, but this would result in different product models for the first slider 42 and the second slider 43, which is not conducive to structural design and parts procurement.

[0117] In this embodiment, the vehicle positioning plate 3 located below the battery fixing plate 2 is also a flat plate. The vehicle positioning plate 3 is connected to the drive end of the corresponding second moving module 6 on one side of this flat plate via two second connectors 32. By providing second connectors 32 on one side of the vehicle positioning plate 3 to connect with the second moving module 6, the two second moving modules 6 can output driving force evenly, enabling the vehicle positioning plate 3 to move stably and ensuring a smooth battery swapping process.

[0118] Meanwhile, the two vehicle positioning parts 33, which are provided on the upper surface of the vehicle positioning plate 3, are positioned on the side of the vehicle positioning plate 3 away from the second connecting member 32, such as... Figure 2 As shown, when the battery mounting plate 2 is stacked on top of the vehicle positioning plate 3, the vehicle positioning part 33 extends upward from the side of the battery mounting plate 2 to achieve positioning relative to the vehicle without obstructing the normal movement of the battery mounting plate 2.

[0119] like Figure 6 As shown, the vehicle positioning plate 3 in this embodiment is also trapezoidal in shape, with relatively parallel short sides 3a and long sides 3b. Two vehicle positioning parts 33 are arranged on the short side 3a side of the vehicle positioning plate 3 along the unlocking / unlocking direction A. At least one end of the short side 3a on which the vehicle positioning parts 33 are provided has a clearance space 34, such as... Figure 7 and Figure 8 As shown, the two clearance spaces 34 are used to avoid the first slider 42 of the two first sliders 42 of the guide module 4 that is close to the vehicle body positioning part 33. Since the vehicle body positioning plate 3 in this embodiment adopts a trapezoidal structure design, it can withstand a high load and has a reliable structure. At the same time, by placing the drive end connected to the second moving module 6 and the vehicle body positioning part 33 on both sides of the vehicle body positioning plate 3, interference between the vehicle body positioning part 33 and the battery fixing plate 2 can be avoided.

[0120] like Figure 2 and Figure 9As shown, the battery mounting assembly 10 in this embodiment also includes trays 7 and elastic members 8. Two trays 7 are distributed above and on both sides of the battery fixing plate 2 along the unlocking direction A. Six elastic members 8 are disposed between each tray 7 and the battery fixing plate 2. These six elastic members 8 are evenly distributed along the periphery of the tray 7, and their elasticity supports the tray 7. The battery fixing plate 2 actually carries the battery through these two trays 7. The elastic members 8 can compress when carrying the battery, thus buffering impact and reducing vibration. The surface of the tray 7 also has clearance holes 71 for the battery positioning part 21 to pass through, allowing the battery positioning part 21 to extend from the center of the tray 7 to position the battery.

[0121] By installing a tray 7 on the battery fixing plate 2, the battery can be supported more effectively and stably, and the elastic elements 8 can be used to cushion the impact of the battery along the height direction during transportation. At the same time, by increasing the number of elastic elements 8 and evenly distributing them, the battery fixing plate 2 provides multi-point support for the tray 7, ensuring that the weight of the battery is evenly transferred to the surface of the battery fixing plate 2. In addition, by providing clearance holes 71 on the surface of the tray 7, the tray 7 and the battery positioning part 21 can be arranged overlapping on the battery fixing plate 2, resulting in a more compact structure.

[0122] like Figure 10 , Figure 11 and Figure 12 As shown, in this embodiment, the lifting mechanism 40 of the battery swapping shuttle 100 is equipped with a lifting guide 401 to guide the battery mounting assembly 10 to move up and down in the vertical direction. Specifically, in this embodiment, the guide is guided by a scissor lift. Compared with other vertical guiding methods, guiding the lifting mechanism by a scissor lift eliminates the need to arrange lifting guide rails 41 vertically on the shuttle frame 20. Therefore, it reduces the occupancy of components in the height direction of the shuttle frame 20, further reducing the overall height of the battery swapping shuttle 100.

[0123] As for the shuttle frame 20 in this embodiment, it is specifically a frame module formed by two opposing crossbeams 201 and two opposing longitudinal beams 202. The frame module also includes two partition plates 203 that are parallel to the longitudinal beams 202 and connected to the two crossbeams 201. The two partition plates 203 are respectively arranged along the length direction of the frame module, and the frame module is divided into a middle area 20a and side areas 20b symmetrically arranged on both sides of the middle area 20a by the partition plates 203.

[0124] Based on this, the walking mechanism 30 in this embodiment includes multiple drive wheel sets 301, which are arranged sequentially along the travel direction of the battery swapping shuttle 100. At least one drive wheel set 301 is provided in each side area 20b of the frame module, and these drive wheel sets 301 can be driven individually.

[0125] By providing at least one drive wheel set 301 in each side area 20b of the frame module, and controlling the travel speed of each drive wheel set 301, multi-directional movement of the battery swapping shuttle 100 can be achieved. This facilitates adjustment of the shuttle's attitude relative to the vehicle, enabling battery swapping to be completed even when the vehicle is parked at an angle. Furthermore, to further improve the stability of the shuttle's horizontal operation, auxiliary wheels 302 are provided at the four corner positions for auxiliary support during horizontal movement.

[0126] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
