Description

[0001] This application claims priority to Chinese patent application CN202111444383.8, filed on November 30, 2021. The entire contents of the aforementioned Chinese patent application are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of electric vehicle battery swapping technology, and in particular to a battery installation device and a battery swapping shuttle. Background Technology

[0003] Currently, electric vehicle battery packs are generally configured in two ways: fixed and swappable. Fixed battery packs are typically mounted directly on the vehicle, serving as the charging source. Swappable battery packs, on the other hand, are usually attached to the vehicle via a removable mounting system. The battery pack can be removed for individual replacement or charging. After charging, the removed battery pack is reinstalled on the vehicle.

[0004] However, for large vehicles, such as heavy-duty or light-duty trucks, the large vehicle body and cargo weight result in high demands for battery pack capacity. Sufficiently large electrical capacity is required to support the vehicle's range of hundreds of kilometers. Therefore, in current technology, large new energy vehicles typically use a top-mounted method to fix a large battery container to the vehicle's frame, with the battery container positioned close to the cab. This creates significant safety hazards for the driver and the vehicle itself during driving and the top-mounted battery swapping process. Furthermore, battery malfunctions can directly cause personal injury to the driver. Additionally, the top-mounted method requires a large enough area for the battery swapping station to operate the hoisting equipment, transfer batteries, and store them, leading to high construction costs.

[0005] Therefore, a safer, more reliable, and easier-to-adopt battery swapping mode is urgently needed for large vehicles. For example, a chassis-based battery swapping mode similar to that used in passenger cars could be adopted. In this mode, battery packs can be installed onto the swapping vehicle using a battery swapping shuttle. The battery swapping shuttle requires two main operations during the swapping process: first, positioning the shuttle and the swapping vehicle to prevent relative displacement and ensure a smooth swap; second, the shuttle needs to perform related movement operations to remove depleted battery packs from the swapping vehicle and install fully charged battery packs. However, both of these operations suffer from drawbacks such as unstable battery pack replacement by the shuttle, low success rate, and low efficiency. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of unstable battery pack replacement, low success rate and low efficiency of battery swapping shuttle in the prior art, and to provide a battery installation device and a battery swapping shuttle.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] A battery installation device, mounted on a battery swapping shuttle, includes:

[0009] The first movable plate has a positioning element for positioning the battery pack. The first movable plate is configured to reciprocate along a first direction. The first movable plate has a groove on one side perpendicular to the first direction. The first movable plate also includes battery tray mounting areas disposed on both sides of the groove. The first movable plate is used to support and drive the battery pack to move.

[0010] The second movable plate is configured to reciprocate along the first direction. The second movable plate is at least partially located in the inner region of the groove. The second movable plate has a limiting portion for limiting the battery mounting device on the battery swapping vehicle. The first direction is the direction of movement of the battery pack during the locking and unlocking process.

[0011] In this design, the first movable plate carries and moves the battery pack to be installed along a first direction, thereby installing the battery pack on the battery swapping vehicle. The second movable plate moves in the same direction as the first movable plate. The spatial arrangement of the first and second movable plates reduces the space occupied when they are installed separately, making the use of space more rational. The limiting part of the second movable plate is used to limit the battery installation device on the battery swapping vehicle, avoiding relative displacement between the battery swapping shuttle and the battery swapping vehicle during the battery pack installation process, which would affect the installation accuracy and efficiency of the battery pack.

[0012] Preferably, the upper surface of the first movable plate and the upper surface of the second movable plate are located on the same plane.

[0013] In this design, the first and second movable plates are arranged on the same plane, which reduces the space occupied in the vertical direction.

[0014] Preferably, the first moving plate and the second moving plate are not coplanar, and the second moving plate is partially located within the groove along the vertical direction.

[0015] In this design, the first and second moving plates are not coplanar, which facilitates their staggered movement. The vertical portion of the second moving plate is located within the groove, reducing the space occupied by the first and second moving plates in the horizontal direction.

[0016] Preferably, the second movable plate includes an upper plate and a lower plate stacked together, the upper plate and the lower plate being fixedly connected, the upper plate being located above the first movable plate, and the lower plate being located below the first movable plate.

[0020] Along the first direction, the end of the connecting plate away from the first moving plate is flush with the side of the lower plate away from the first moving plate.

[0021] In this solution, the connecting plate connects the upper body and the lower plate in a staggered manner, so that the upper plate can reach the designated position by moving the lower plate along a shorter path.

[0022] Preferably, the upper plate is provided with weight-reducing holes, and the limiting part is provided on the side of the upper plate away from the first moving plate.

[0023] In this design, the weight-reducing holes not only save materials but also reduce the weight of the upper plate, making the battery mounting device lighter. The limiting part is used to fix the battery mounting device to the battery swapping vehicle to prevent relative displacement between the two, which would affect the battery swapping efficiency and accuracy.

[0024] Preferably, the first movable plate has a battery pack fixing area corresponding to the inner edge of the groove, and the battery pack fixing area is provided with the positioning member, which is a rod-shaped structure.

[0025] In this design, the positioning component can be inserted into the positioning hole in the battery pack, ensuring the stability of the battery pack during movement and lifting.

[0026] Preferably, the first movable plate has battery tray mounting areas on both sides, and the battery pack fixing area is located between the two battery tray mounting areas.

[0027] In this design, battery tray mounting areas are provided on both sides of the first movable plate to jointly support the battery pack, facilitating the transfer of force from the battery pack to the tray, which in turn transfers the force to the first movable plate, making the movement of the battery pack more stable.

[0028] Preferably, the battery mounting device further includes a tray and an elastic mechanism, the tray being used to support the battery pack, and the tray being movably connected to the first movable plate via the elastic mechanism.

[0029] In this solution, a tray is used to support the battery pack, which ensures the stability of the battery pack during disassembly and installation, and helps to improve the efficiency of disassembly and installation.

[0038] The lower end of the outer casing is connected to the power unit, the upper end of the outer casing is connected to the sleeve device, and the internal space of the outer casing is used to accommodate a part of the sleeve device and at least a part of the power unit.

[0039] In this design, the power unit and the sleeve device are housed in the same outer casing, resulting in a compact structure and reasonable layout. The pre-compression device provides an upward preload force. In the working state, the pre-compression device can continuously provide an upward restoring force; in the non-working state, the pre-compression device can maintain the stability of the sleeve device within a certain force range.

[0040] Preferably, the limiting part is a positioning pin, which is used to limit the battery mounting device on the battery swapping vehicle.

[0041] In this solution, the positioning pins are designed to work in conjunction with the positioning holes on the battery swapping vehicle, ensuring that the battery installation device can be stably positioned on the battery swapping vehicle. This prevents relative displacement between the battery swapping shuttle and the battery swapping vehicle during the battery pack installation process, which would affect the installation accuracy and efficiency of the battery pack.

[0042] Preferably, the battery mounting device further includes two sets of first drive mechanisms and two sets of second drive mechanisms;

[0045] The two sets of second drive mechanisms are located inside the two sets of first drive mechanisms.

[0046] In this solution, the first and second moving plates are driven to move along the first direction by the first driving mechanism and the second driving mechanism respectively, which makes the movement of the first and second moving plates more flexible and improves the movement efficiency; the first driving mechanism and the second driving mechanism are provided in two sets, which improves the load-bearing capacity of the first and second moving plates and makes the movement of the first and second moving plates more stable.

[0047] Preferably, both the first drive mechanism and the second drive mechanism include a driver, a power output shaft, and a transmission part;

[0048] The power output shaft is fitted with the transmission part and is threadedly engaged with the transmission part; the transmission part is connected to the first moving plate or the second moving plate.

[0049] The driver is used to drive the power output shaft to rotate;

[0050] The battery mounting device also includes a base, and the bottom of the driver is fixedly mounted on the base.

[0051] In this design, the driver drives the power output shaft to rotate, and the transmission unit converts the rotational motion of the power output shaft into linear motion of the first and second moving plates along the axial direction of the power output shaft, ensuring the moving efficiency and smoothness of the first and second moving plates. The base ensures the stability of the driver.

[0052] Preferably, the battery mounting device further includes a first guiding mechanism and a second guiding mechanism;

[0053] The first movable plate is slidably connected to the first guide mechanism, and the second movable plate is slidably connected to the second guide mechanism;

[0054] Both the first guide mechanism and the second guide mechanism include a sliding part. The sliding part of the first guide mechanism is used to support the first moving plate, and the sliding part of the second guide mechanism is used to support the second moving plate.

[0055] The battery mounting device also includes a base, and the base bottoms of the first guide mechanism and the second guide mechanism are both fixedly mounted on the base;

[0056] Alternatively, the base of the first guide mechanism may be disposed on the base, and the second guide mechanism may be disposed on the first movable plate;

[0057] Alternatively, the base of the second guide mechanism may be disposed on the base, and the first guide mechanism may be disposed on the second movable plate.

[0058] In this scheme, the first guide mechanism and the second guide mechanism guide the movement of the first moving plate and the second moving plate respectively, ensuring that the first moving plate and the second moving plate can move along the preset direction during the movement process and avoid deviation.

[0059] Preferably, the first driving mechanism and the first guiding mechanism are disposed below the first moving plate;

[0060] The second drive mechanism and the second guide mechanism are located below the second movable plate.

[0061] In this design, the first drive mechanism is located below the first movable plate, which facilitates the placement of the battery pack above the first movable plate; the first guide mechanism and the second guide mechanism are respectively located below the first movable plate and the second movable plate, which simultaneously serve as guides and supports for the first movable plate and the second movable plate.

[0062] Preferably, there are two sets of the first guiding mechanism, and the two sets of the first guiding mechanism are respectively located on opposite sides of the first moving plate;

[0063] The second guide mechanism has two sets, and the two sets of the second guide mechanism are located inside the two sets of the first guide mechanism.

[0064] In this design, the arrangement of two sets of first guide mechanisms and two sets of second guide mechanisms makes the movement of the first and second moving plates more stable; the two sets of second guide mechanisms are located inside the two sets of first guide mechanisms, making reasonable use of the installation space.

[0065] Preferably, both the first guiding mechanism and the second guiding mechanism include a guide rail and a sliding part, one end of the sliding part is slidably engaged with the guide rail, and the other end of the sliding part is connected to the first moving plate or the second moving plate.

[0066] In this solution, the sliding cooperation between the guide rail and the sliding part reduces the frictional resistance experienced by the first moving plate on the first guide mechanism and the second moving plate on the second guide mechanism, resulting in smoother movement and improved movement efficiency.

[0067] Preferably, the guide rail is arranged along the first direction, and the guide rail extends from one side of the battery swapping shuttle to the opposite side of the battery swapping shuttle.

[0069] Preferably, each guide rail is provided with a guide rail mounting base at its bottom, and the guide rail is fixedly connected to the guide rail mounting base.

[0070] In this design, the guide rail mounting base makes the installation of the guide rail more secure, further ensuring the stability of the first and second moving plates as they run on the first and second guiding mechanisms, respectively.

[0071] Preferably, the guide rail mounting base includes at least a first base plate, a first reinforcing rib plate, and a second reinforcing rib plate;

[0072] One side of the first reinforcing rib and one side of the second reinforcing rib are respectively connected to the two sides of the first substrate, and the other side of the first reinforcing rib and the other side of the second reinforcing rib are fixedly connected to the first substrate.

[0073] Both the first reinforcing rib and the second reinforcing rib include a horizontal bending portion and a vertical bending portion, wherein the horizontal bending portion is connected to the base and the vertical bending portion is connected to the first substrate;

[0074] The guide rail is mounted on the first base plate.

[0075] In this design, the arrangement of the first base plate, the first reinforcing rib, and the second reinforcing rib gives the guide rail mounting base a Z-shaped cross-section, resulting in greater load-bearing capacity and higher stability, thereby enhancing the stability of the guide rail.

[0076] Preferably, the battery mounting device further includes a positioning detection device and an origin detection device. The positioning detection device is used to detect whether the first moving plate and the second moving plate have reached a preset position, and the origin detection device is used to detect whether the first moving plate and the second moving plate are located at the origin position.

[0077] The positioning detection device includes two first proximity switches and two first triggers. The two first proximity switches are respectively disposed on the side walls of the mounting chambers of the first moving plate and the second moving plate, and the two first triggers are respectively disposed on the first moving plate and the second moving plate.

The two second proximity switches are respectively disposed on the side walls of the mounting chambers of the first moving plate and the second moving plate, and the two second triggers are respectively disposed on the first moving plate and the second moving plate.

[0079] In this solution, the positioning detection device can detect whether the first and second moving plates have reached the preset position, ensuring the accuracy of the movement of the first and second moving plates, thereby ensuring the accuracy of the movement of the battery pack and improving the battery swapping efficiency. The origin detection device is used to detect whether the first and second moving plates are located at the origin position. When the first and second moving plates need to be reset, the origin detection device can be used to determine whether the reset has been completed, improving the accuracy of the reset of the first and second moving plates.

[0149] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments described herein.

[0150] like Figures 1 to 4As shown, this embodiment provides a battery installation device, mounted on a battery swapping shuttle 100, which includes a first movable plate 1 and a second movable plate 2. The first movable plate 1 has a positioning member 11 for positioning a battery pack 200. The first movable plate 1 is configured to reciprocate along a first direction. The first movable plate 1 has a groove 12 on one side perpendicular to the first direction. The first movable plate 1 also includes battery tray mounting areas 13 disposed on both sides of the groove 12. The first movable plate 1 is used to carry and drive the battery pack 200 to move. The second movable plate 2 is configured to reciprocate along the first direction. The second movable plate 2 is at least partially located in the inner area of ​​the groove 12. The second movable plate 2 has a limiting part 21, which is used to limit the battery installation device on the battery swapping vehicle. The first direction is the direction of movement of the battery pack 200 during the locking and unlocking process. Figure 1 The X direction is shown in the diagram.

[0151] The first movable plate 1 is used to carry and move the battery pack 200 to be installed along the first direction, thereby installing the battery pack 200 on the battery swapping vehicle; the second movable plate 2 moves in the same direction as the first movable plate 1. The spatial arrangement of the first movable plate 1 and the second movable plate 2 reduces the space occupied when they are set separately, making the use of space more reasonable; the limiting part 21 of the second movable plate 2 is used to limit the battery installation device on the battery swapping vehicle, avoiding relative displacement between the battery swapping shuttle 100 and the battery swapping vehicle during the installation of the battery pack 200, which would affect the installation accuracy and efficiency of the battery pack 200.

[0152] In this embodiment, the first moving plate 1 and the second moving plate 2 are not coplanar, which facilitates the staggered movement of the first moving plate 1 and the second moving plate 2; the second moving plate 2 is partially located in the groove 12 along the vertical direction, which reduces the space occupied by the first moving plate 1 and the second moving plate 2 in the horizontal direction.

[0153] In other embodiments, the upper surfaces of the first movable plate 1 and the second movable plate 2 may also be located on the same plane. The coplanar arrangement of the first movable plate 1 and the second movable plate 2 can reduce the space occupied in the vertical direction.

[0154] In this embodiment, the second movable plate 2 includes an upper plate 22 and a lower plate 23 stacked together. The upper plate 22 and the lower plate 23 are fixedly connected. The upper plate 22 is located above the first movable plate 1, and the lower plate 23 is located below the first movable plate 1. The upper plate 22 and the lower plate 23 are connected as a whole by a connecting plate 24 and move together. The upper plate 22 is provided with a limiting part 21 for limiting the battery mounting device on the battery swapping vehicle. The lower plate 23 is connected to a guide mechanism to facilitate driving the second movable plate 2.

[0155] In this embodiment, the second movable plate 2 further includes a connecting plate 24, which is connected between the upper plate 22 and the lower plate 23 along a first direction. Specifically, in this embodiment, two connecting plates 24 are provided between the upper plate 22 and the lower plate 23, and the two connecting plates 24 are respectively located on the two sides of the upper plate 22 along the first direction. The connecting plate 24 passes through the groove 12 in a direction perpendicular to the first movable plate 1, that is, in the vertical direction, the connecting plate 24 passes through the groove 12, so that the upper plate 22 connected to the connecting plate 24 is located above the first movable plate 1, and the lower plate 23 connected to the connecting plate 24 is located below the first movable plate 1. Along the first direction, the end of the connecting plate 24 near the first movable plate 1 is flush with the side of the upper plate 22 near the first movable plate 1. Along the first direction, the end of the connecting plate 24 away from the first movable plate 1 is flush with the side of the lower plate 23 away from the first movable plate 1. The connecting plate 24 connects the upper body and the lower plate 23 in a staggered manner, so that the upper plate 22 can reach the designated position by moving the lower plate 23 along a shorter path.

[0156] In this embodiment, the upper plate 22 is provided with a weight-reducing hole 221, and a limiting part 21 is provided on the side of the upper plate 22 away from the first moving plate 1. The weight-reducing hole 221 not only saves materials, but also reduces the weight of the upper plate 22, making the battery installation device lighter; the limiting part 21 is used to limit the battery installation device and the battery swapping vehicle to prevent relative displacement between the two, which would affect the battery swapping efficiency and accuracy.

[0157] In this embodiment, the first movable plate 1 has a battery pack 200 fixing area 14 corresponding to the inner edge of the groove 12, that is, along the first direction, the area adjacent to the groove 12 is the battery pack 200 fixing area 14; the battery pack 200 fixing area 14 is provided with a positioning member 11, which is a rod-shaped structure. The positioning member 11 can be inserted into the positioning hole in the battery pack 200, ensuring the stability of the battery pack 200 during movement and lifting.

[0158] In this embodiment, the first movable plate 1 has battery tray mounting areas 13 on both sides perpendicular to the first direction, and a battery pack 200 fixing area 14 is located between the two battery tray mounting areas 13. The two battery tray mounting areas 13 are located on both sides of the groove 12. The battery tray mounting areas 13 on both sides of the first movable plate 1 are used to jointly support the battery pack 200, so that the battery pack 200 can transfer force to the tray 3, and the tray 3 can transfer force to the first movable plate 1, making the movement of the battery pack 200 more stable.

[0159] In this embodiment, the battery installation device further includes a tray 3 and an elastic mechanism 4. The tray 3 supports the battery pack 200, and the tray 3 is movably connected to the first movable plate 1 through the elastic mechanism 4. Using the tray 3 to support the battery pack 200 ensures the stability of the battery pack 200 during disassembly and installation, which is beneficial to improving the efficiency of disassembly and installation of the battery pack 200. The elastic mechanism 4 makes the tray 3 more stable during lifting, providing a certain buffering effect and preventing the battery pack 200 on the tray 3 from being subjected to hard impacts.

[0160] In this embodiment, the battery installation device further includes a lifting mechanism 5, a base 6, and an unlocking component 7. The base 6 is disposed on the lifting mechanism 5, and the first movable plate 1 is disposed on the base 6. The unlocking component 7 is disposed on the first movable plate 1 and passes through the tray 3. The unlocking component 7 is used to unlock the battery pack 200 from the battery swapping vehicle when the battery pack 200 is lifted. The lifting mechanism 5 can lift the base 6 and the first movable plate 1 to move vertically. The unlocking component 7 can trigger the lifting rod 202 in the battery pack 200, and the lifting rod 202 further triggers the locking mechanism 10 on the battery swapping vehicle, thereby unlocking or locking the battery pack 200.

[0161] In some other embodiments, the unlocking element 7 is a torque unlocking element, such as... Figure 8 As shown, the torque unlocking component is used to apply torque to cooperate with the unlocking mechanism to achieve unlocking. The torque unlocking component includes a sleeve device 71, a power unit 72, a pre-compression device 73, and a housing 74; the upper end of the sleeve device 71 is connected to the lifting rod 202 in the battery pack 200, and the sleeve device 71 can rotate to transmit torque to the lifting rod 202 in the battery pack 200; the power output end of the power unit 72 is connected to the power input end of the sleeve device 71, and is used to output power to drive the sleeve device 71 to rotate; one end of the pre-compression device 73 abuts against the sleeve device 71, and the other end abuts against the power unit 72, and the pre-compression device 73 is in a pre-compression state, used to provide an upward pre-tightening force to the sleeve device 71; the lower end of the housing 74 is connected to the power unit 72, and the upper end of the housing 74 is connected to the sleeve device 71, and the internal space of the housing 74 is used to accommodate a part of the sleeve device 71 and at least a part of the power unit 72. The power unit 72 and the sleeve device 71 are housed in the same outer casing 74, making the structure compact and the layout reasonable. The preload device 73 provides an upward preload force. In the working state, the preload device 73 can continuously provide an upward restoring force. In the non-working state, the preload device 73 can maintain the stability of the sleeve device 71 within a certain force range.

[0162] The unlocking process of the aforementioned torque unlocking component is as follows:

[0163] When the battery swapping shuttle performs the operation of removing the vehicle battery pack 200, the shuttle first moves to directly below the battery pack 200 via the walking mechanism, and then the lifting mechanism 5 raises the first moving plate 1. At this time, the torque unlocking component on the first moving plate 1 engages with the locking mechanism 10 on the vehicle via the sleeve device 71. Further, the power unit 72 of the torque unlocking component outputs torque, which is transmitted to the locking mechanism 10 on the vehicle via the sleeve device 71. The locking mechanism 10 on the vehicle is unlocked, and the vehicle battery pack 200 falls naturally. Subsequently, the lifting mechanism 5 lowers the entire battery swapping unit, and the walking mechanism moves the battery swapping shuttle out of the working position, completing the removal process of the vehicle battery pack 200.

[0164] When the battery swapping shuttle performs the installation of the vehicle battery pack 200, the traveling mechanism first adjusts the position of the shuttle carrying the vehicle battery pack 200 to directly below the vehicle battery pack 200, and then the lifting mechanism 5 raises the first moving plate 1 carrying the vehicle battery pack 200. At this time, the torque unlocking component on the first moving plate 1 is engaged with the locking mechanism 10 on the vehicle through the sleeve device 71. Further, the power unit 72 of the torque unlocking component outputs torque, which is transmitted to the locking mechanism 10 on the vehicle through the sleeve device 71. The locking mechanism 10 on the vehicle is unlocked, and the vehicle battery pack 200 falls naturally, completing the removal of the vehicle battery pack 200.

[0165] When the unlocking element 7 is a torque-activated unlocking element, the corresponding locking mechanism 10 can be a threaded lock. Specifically, such as... Figure 9 As shown, the locking mechanism 10 includes a first lock base 1001, which has a first opening 1002 extending vertically. A first threaded portion 1003, which is an internal thread, is provided within the first opening 1002. A locking connection structure 700 is provided on the battery pack for engaging with the locking mechanism 10 on the vehicle body longitudinal beam to achieve locking. The locking connection structure 700 includes a mounting base 701 and an unlocking member 7. A second opening 702 extending vertically is provided within the mounting base 701. The unlocking member 7 is vertically disposed within the second opening 702 and is movable vertically relative to the mounting base 701. The unlocking member 7 has a second threaded portion 703 that engages with the first threaded portion 1003, thereby achieving locking and unlocking of the locking mechanism 10 and the locking connection structure 700.

[0166] When the unlocking element 7 is a torque-activated unlocking element, the locking mechanism 10 can also be a T-type lock. Specifically, as shown in the figure... Figure 10As shown, the locking mechanism 10 includes a first lock base 1001, which has a first opening 1002 extending vertically. The first opening 1002 is a square hole, and a first limiting portion 1004 is located above the first opening 1002. The lock connection structure 700 includes an unlocking member 7, above which is a locking rod 704 extending horizontally. The locking rod 704 is a columnar body and is horizontally positioned on top of the unlocking member 7. The locking rod 704 and the unlocking member 7 together form a T-shaped structure. When the locking rod 704 is at a first angle, it can pass through the first opening 1002 and enter the first limiting portion 1004 of the first lock base 1001. When the locking rod 704 is rotated to a second angle, it can be restricted within the first limiting portion 1004, thereby fixing the locking mechanism 10 and the lock connection structure 700 relative to each other.

[0167] In this embodiment, the limiting part 21 is a positioning pin, which is used to limit the battery installation device on the battery swapping vehicle. By cooperating with the positioning hole on the battery swapping vehicle, the positioning pin ensures that the battery installation device can be stably limited on the battery swapping vehicle, avoiding relative displacement between the battery swapping shuttle 100 and the battery swapping vehicle during the installation of the battery pack 200, which would affect the installation accuracy and efficiency of the battery pack 200.

[0168] In this embodiment, the battery mounting device further includes two sets of first driving mechanisms 81 and two sets of second driving mechanisms 82. The two sets of first driving mechanisms 81 are respectively disposed on opposite sides of the first movable plate 1 and are used to drive the first movable plate 1 to move along a first direction. The two sets of second driving mechanisms 82 are respectively disposed on opposite sides of the second movable plate 2 and are used to drive the second movable plate 2 to move along the first direction. The two sets of second driving mechanisms 82 are located inside the two sets of first driving mechanisms 81, which improves space utilization. By driving the first movable plate 1 and the second movable plate 2 to move along the first direction by the first driving mechanisms 81 and the second driving mechanisms 82 respectively, the movement of the first movable plate 1 and the second movable plate 2 is more flexible and the movement efficiency is improved. The first driving mechanism 81 and the second driving mechanism 82 are provided in two sets, which improves the load-bearing capacity of the first movable plate 1 and the second movable plate 2 and makes the movement of the first movable plate 1 and the second movable plate 2 more stable.

[0169] In this embodiment, both the first driving mechanism 81 and the second driving mechanism 82 include a driver 801, a power output shaft 802, and a transmission part 803. The transmission part 803 is sleeved on the power output shaft 802 and threadedly engaged with it. The transmission part 803 is connected to the first moving plate 1 or the second moving plate 2. The driver 801 is used to drive the power output shaft 802 to rotate. The bottom of the driver 801 is fixedly mounted on the base 6. The driver 801 drives the power output shaft 802 to rotate, and the transmission part 803 converts the rotational motion of the power output shaft 802 into linear motion of the first moving plate 1 and the second moving plate 2 along the axial direction of the power output shaft 802, ensuring the moving efficiency and smoothness of the first moving plate 1 and the second moving plate 2. The base 6 ensures the stability of the driver 801.

[0170] In this embodiment, the battery mounting device further includes a first guiding mechanism 91 and a second guiding mechanism 92; a first movable plate 1 is slidably connected to the first guiding mechanism 91, and a second movable plate 2 is slidably connected to the second guiding mechanism 92; both the first guiding mechanism 91 and the second guiding mechanism 92 include a sliding portion 901, the sliding portion 901 of the first guiding mechanism 91 is used to support the first movable plate 1, and the sliding portion 901 of the second guiding mechanism 92 is used to support the second movable plate 2; the base of the first guiding mechanism 91 and the base of the second guiding mechanism 92 are both fixedly disposed on the base 6. The first guiding mechanism 91 and the second guiding mechanism 92 respectively guide the movement of the first movable plate 1 and the second movable plate 2, ensuring that the first movable plate 1 and the second movable plate 2 can move along a preset direction during the movement process, avoiding deviation.

[0171] In other embodiments, the base of the first guide mechanism 91 may be disposed on the base 6, and the second guide mechanism 92 may be disposed on the first movable plate 1; or the base of the second guide mechanism 92 may be disposed on the base 6, and the first guide mechanism 91 may be disposed on the second movable plate 2.

[0172] In this embodiment, the first driving mechanism 81 and the first guiding mechanism 91 are disposed below the first movable plate 1; the second driving mechanism 82 and the second guiding mechanism 92 are disposed below the second movable plate 2. The first driving mechanism 81 is disposed below the first movable plate 1, thereby facilitating the placement of the battery pack 200 above the first movable plate 1; the first guiding mechanism 91 and the second guiding mechanism 92 are respectively disposed below the first movable plate 1 and the second movable plate 2, serving to guide and support the first movable plate 1 and the second movable plate 2 simultaneously.

[0173] In this embodiment, there are two sets of first guide mechanisms 91, located on opposite sides of the first movable plate 1; there are also two sets of second guide mechanisms 92, located inside the two sets of first guide mechanisms 91. The arrangement of the two sets of first guide mechanisms 91 and the two sets of second guide mechanisms 92 makes the movement of the first movable plate 1 and the second movable plate 2 more stable; the placement of the two sets of second guide mechanisms 92 inside the two sets of first guide mechanisms 91 makes efficient use of the installation space.

[0174] In this embodiment, both the first guiding mechanism 91 and the second guiding mechanism 92 include a guide rail 902 and a sliding part 901. One end of the sliding part 901 is slidably engaged with the guide rail, and the other end of the sliding part 901 is connected to the first moving plate 1 or the second moving plate 2. Through the sliding engagement of the guide rail 902 and the sliding part 901, the frictional resistance experienced by the first moving plate 1 on the first guiding mechanism 91 and the second moving plate 2 on the second guiding mechanism 92 is reduced, resulting in smoother movement and improved movement efficiency.

[0175] In this embodiment, the guide rail 902 is arranged along the first direction and extends from one side of the battery swapping shuttle 100 to the opposite side of the battery swapping shuttle 100, so that the first moving plate 1 and the first moving plate 1 have a large moving stroke, which is convenient for adapting to vehicle models.

[0176] In this embodiment, each guide rail 902 is provided with a guide rail mounting seat 903 at its bottom, and the guide rail 902 is fixedly connected to the guide rail mounting seat 903. The guide rail mounting seat 903 makes the installation of the guide rail 902 more secure, and further ensures the stability of the first moving plate 1 and the second moving plate 2 running on the first guide mechanism 91 and the second guide mechanism 92 respectively.

[0177] In this embodiment, the guide rail mounting base 903 includes at least a first base plate 9031, a first reinforcing rib plate 9032, and a second reinforcing rib plate 9033. One side of the first reinforcing rib plate 9032 and one side of the second reinforcing rib plate 9033 are respectively connected to both sides of the first base plate 9031, and the other side of the first reinforcing rib plate 9032 and the other side of the second reinforcing rib plate 9033 are both fixedly connected to the first base plate 9031. Both the first reinforcing rib plate 9032 and the second reinforcing rib plate 9033 include a horizontal bending portion 9034 and a vertical bending portion 9035. The horizontal bending portion 9034 is connected to the base 6, and the vertical bending portion 9035 is connected to the first base plate 9031. The guide rail 902 is disposed on the first base plate 9031. Through the arrangement of the first base plate 9031, the first reinforcing rib plate 9032, and the second reinforcing rib plate 9033, the guide rail mounting base 903 has a Z-shaped cross-section, resulting in greater load-bearing capacity and higher stability, thereby enhancing the stability of the guide rail 902.

[0178] In this embodiment, the battery installation device further includes a positioning detection device and an origin detection device. The positioning detection device is used to detect whether the first moving plate 1 and the second moving plate 2 have reached the preset position, ensuring the accuracy of the movement of the first moving plate 1 and the second moving plate 2, thereby ensuring the accuracy of the movement of the battery pack 200 and improving the battery swapping efficiency. The origin detection device is used to detect whether the first moving plate 1 and the second moving plate 2 are located at the origin position. When the first moving plate 1 and the second moving plate 2 need to be reset, the origin detection device can be used to determine whether the reset has been completed, improving the accuracy of the reset of the first moving plate 1 and the second moving plate 2.

[0179] The positioning detection device includes two first proximity switches and two first triggers. The two first proximity switches are respectively located on the side walls of the mounting chambers of the first moving plate 1 and the second moving plate 2. The two first triggers are respectively located on the first moving plate 1 and the second moving plate 2. When the first moving plate 1 and the second moving plate 2 move to the designated position, the first triggers on the first moving plate 1 and the second moving plate 2 can trigger the corresponding first proximity switches, thereby issuing a positioning signal.

[0180] The origin detection device includes two second proximity switches and two second triggers. The two second proximity switches are respectively located on the side walls of the mounting chambers of the first moving plate 1 and the second moving plate 2, and the two second triggers are respectively located on the first moving plate 1 and the second moving plate 2. When the first moving plate 1 and the second moving plate 2 move to the origin position, the second triggers on the first moving plate 1 and the second moving plate 2 can trigger the corresponding second proximity switches, thereby sending a reset signal.

[0181] A battery swapping shuttle 100 includes the aforementioned battery mounting device.

[0182] The battery swapping shuttle 100 connects the limiting part 21 with the battery swapping vehicle by moving the second moving plate 2, thereby positioning itself and the battery swapping vehicle and avoiding relative displacement between the battery swapping shuttle 100 and the battery swapping vehicle, thus ensuring the installation accuracy and efficiency of the battery pack 200; the battery pack 200 is moved to the designated position by moving the first moving plate 1 and installed on the battery swapping vehicle.

[0183] The battery pack 200 and locking mechanism 10 in this embodiment will be described below.

[0184] like Figures 5 to 6As shown, the battery pack 200 is provided with a mounting bracket 201, which is located at the top of the battery pack 200 corresponding to the locking mechanism 10 on the vehicle body longitudinal beam. The battery pack 200 is locked by inserting the mounting bracket 201 into the locking mechanism 10. Inside the battery pack 200, at the position corresponding to the locking mechanism 10, there is a lifting rod 202. The lifting rod 202 is used to lift the locking linkage 1013 of the locking mechanism 10. The lifting rod 202 is vertically arranged and can move along the vertical direction.

[0185] like Figure 7 As shown, the locking mechanism 10 on the battery swapping vehicle has a through slot for the mounting pieces 201 to pass through. Specifically, the through slot extends along the width direction of the locking mechanism 10. The locking mechanism 10 includes a primary lock 101, which includes three primary lock bases 1011, three primary lock tongues 1012, and a locking link 1013. The through slot includes a primary lock groove 1014. The primary lock bases 1011 have horizontally penetrating, inverted L-shaped primary lock grooves 1014. The primary lock bases 1011 and primary lock tongues 1012 are arranged in a one-to-one correspondence. The primary lock bases 1011 are set on the side wall of the vehicle's longitudinal beam. The first end of the primary lock tongue 1012 is rotatably connected to the primary lock base 1011, and the second end of the primary lock tongue 1012 is rotatably connected to the locking link 1013. The three mounting pieces 201 on the electric vehicle battery pack 200 pass through the primary lock grooves 1014. When the locking link 1013 is subjected to the unlocking mechanism of the battery swapping equipment, the locking link 1013 drives the primary locking tongue 1012 to rotate and open the opening of the primary locking groove 1014. The hook 201 enters and exits the primary locking groove 1014 through the opening of the primary locking groove 1014.

[0186] The battery swapping process for electric vehicles using a battery swapping shuttle is as follows:

[0187] The battery swapping shuttle has a traveling mechanism. The shuttle moves via this mechanism to a position directly beneath the battery pack 200 of the battery swapping vehicle. A first driving mechanism 81 drives a first moving plate 1 to move along a first direction, positioning it directly beneath the battery pack 200. A second driving mechanism 82 drives a second moving plate 2 to move along the first direction, aligning the limiting portion 21 on the second moving plate 2 with the vehicle body positioning hole of the battery swapping vehicle. A lifting mechanism 5 lifts the moving plate assembly, inserting the limiting portion 21 into the vehicle body positioning hole, ensuring no relative displacement between the shuttle and the vehicle. Simultaneously, the first moving plate 1 is lifted by the lifting mechanism 5, inserting its positioning member 11 into the positioning hole of the battery pack 200. In other embodiments, the limiting portion 21 may be positioned before the positioning member 11. Furthermore, the unlocking element 7 on the first moving plate 1 contacts and lifts the lifting rod 202 in the battery pack 200, and the lifting rod 202 acts on the locking linkage 1013 of the locking mechanism 10.

[0188] When locking: the lifting mechanism 5 drives the unlocking component 7 to push the lifting rod 202, which in turn pushes the locking link 1013, opening the locking mechanism 10. The mounting component 201 on the battery pack 200 is then pushed into the first-level lock groove 1014 of the locking mechanism 10. The lifting mechanism 5 then lowers the first moving plate 1, causing the locking link 1013 to descend, thus locking the device.

[0189] During unlocking: After the plate moving assembly moves the battery pack 200 to the inside of the inverted L-shaped primary lock groove 1014 of the locking mechanism 10, the lifting mechanism 5 drives the unlocking component 7 to push the lifting rod 202, which in turn pushes the locking linkage 1013, thus opening the locking mechanism 10. The plate moving assembly then moves the battery pack 200 to the outside of the unlocking opening of the L-shaped groove, exiting the vehicle-side locking mechanism 10 and achieving unlocking.

[0190] 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.
