Description

Technical Field

[0001] This invention relates to the field of electric vehicle battery swapping technology, and particularly to a battery swapping platform, battery swapping equipment, and battery swapping station. Background Technology

[0002] 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.

[0003] Currently, for large vehicles, the battery swapping model mainly adopts the chassis-based battery swapping mode used in passenger cars. In the chassis-based battery swapping mode, the battery pack can be installed on the electric vehicle through battery pack replacement equipment. In order to facilitate the installation and removal of the battery pack, the battery pack replacement equipment needs to be initially positioned with the electric vehicle. After the initial positioning is completed, the battery swapping platform on the battery pack replacement equipment can perform relevant movement operations to remove the depleted battery pack from the electric vehicle and install the fully charged battery pack on the electric vehicle. Existing battery pack replacement equipment, such as the battery pack replacement equipment disclosed in application number 2017112442213 and invention titled "Shuttle Battery Pack Replacement Equipment and Battery Swapping Station Including the Same," only allows the battery swapping platform above it to move linearly along the length of the vehicle after the battery pack replacement equipment has moved to the bottom of the electric vehicle and completed its initial positioning. It lacks the function of adjusting movement in the width direction of the vehicle, resulting in a relatively limited adjustment direction and low positioning accuracy for the battery pack. At the same time, it has high requirements for the size of the battery pack and the overall vehicle compatibility, making it unable to meet the positioning and installation needs of different sized chassis and battery packs. This is not conducive to the battery swapping equipment being compatible with more vehicle models and battery pack specifications. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing battery swapping platform when replacing battery packs of electric vehicles, which has a single direction of adjustment and cannot meet the replacement needs of battery packs of different models and sizes. The present invention provides a battery swapping platform, battery swapping equipment and battery swapping station.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A battery swapping platform for installing and removing battery packs from electric vehicles, the battery swapping platform comprising:

[0007] Support section;

[0008] A battery mounting section is provided on the support section, and the battery mounting section is used to install and remove the battery pack on the electric vehicle;

[0009] The driving unit is used to drive the battery mounting part to move relative to the support part along a first direction and a second direction;

[0010] The first direction is perpendicular to the second direction.

[0011] In this solution, the support unit serves as the supporting structure for the battery swapping platform, providing stable support for the battery installation unit and ensuring sufficient stability during the battery pack installation and removal process. The battery installation unit can remove the depleted battery pack from the electric vehicle and install the fully charged battery pack onto it. The drive unit can drive the battery installation unit to move along a first and a second direction that are perpendicular to each other. This allows the battery installation unit to adjust its position within the plane containing the first and second directions when positioning itself relative to the battery pack on the electric vehicle. This avoids the shortcomings of traditional positioning methods, where the battery swapping platform can only move along a single linear direction and has a small positioning adjustment range. It improves the positioning adjustment range and positioning accuracy of the battery swapping platform and can adapt to more vehicle models and battery pack specifications.

[0012] Preferably, the driving unit includes a first driving unit and a second driving unit, wherein the first driving unit is used to drive the battery mounting unit to move along the first direction, and the second driving unit is used to drive the battery mounting unit to move along the second direction.

[0013] In this solution, the battery mounting section is driven to move along the first direction and the second direction by the first driving section and the second driving section respectively. The two driving sections are independent and flexible, and can also drive each other in coordination, so that the battery swapping platform can be accurately positioned in the plane containing the first direction and the second direction. This improves the adjustment range of the battery swapping platform and facilitates the positioning, unlocking and moving of the battery pack.

[0014] Preferably, the battery swapping platform further includes a moving part, the battery mounting part is disposed on the support part via the moving part, and the first driving part is used to drive the moving part to move along the first direction on the support part.

[0015] In this solution, the first driving unit drives the moving unit to move along the first direction, thereby causing the battery mounting unit on the moving unit to move along the first direction. The moving unit provides a moving platform for the battery mounting unit, thereby making the movement of the battery mounting unit along the first direction more stable.

[0016] Preferably, the first driving part includes a first driving motor and a first lead screw. One end of the first lead screw is connected to the power output end of the first driving motor, and the other end of the first lead screw is mounted on the support part through a first mounting seat. A first connecting block is sleeved on the first lead screw, and the first connecting block is connected to the moving part.

[0017] In this scheme, the first drive motor drives the first lead screw to rotate, the first connecting block is sleeved on the first lead screw, and converts the rotational motion of the first lead screw into the linear motion of the moving part connected to it along the axis of the first lead screw, thus ensuring the moving efficiency and smoothness of the moving part.

[0018] Preferably, the movable part is provided with a first guide part extending along the second direction, the first guide part being used to guide the battery mounting part to move along the second direction.

[0019] In this solution, the first guide section ensures that the battery mounting section does not deviate from the preset direction during its movement along the second direction, thereby guaranteeing the accuracy of the battery mounting section's movement and improving its efficiency.

[0020] Preferably, the movable part has a receiving groove recessed downward from the upper surface of the movable part, the receiving groove being used to receive the second driving part, the second driving part being connected to the battery mounting part, and the second driving part being used to drive the battery mounting part to move along the first guide part.

[0021] In this design, the recessed receiving groove of the moving part provides installation space for the second drive part, while reducing the overall height of the battery swapping platform, making the structure of the entire battery swapping platform more compact and easier to adapt to more models with lower chassis height; the second drive part can drive the battery mounting part to move along the first guide part on the moving part, realizing the movement of the battery mounting part in the second direction, which facilitates the positioning of the battery mounting part with the battery pack on the electric vehicle.

[0022] Preferably, the battery mounting part includes a vehicle positioning part and a battery positioning part. The vehicle positioning part is disposed on the support part and is used to position the vehicle positioning part with the electric vehicle. The battery positioning part is disposed on the support part and is used to position the battery pack. The receiving slot is provided with two second driving parts, which are respectively used to drive the vehicle positioning part and the battery positioning part to move along the first guide part.

[0023] In this solution, the vehicle positioning unit can achieve positioning between the battery swapping platform and the electric vehicle, ensuring that there is no relative displacement between them during the battery swapping process, thus providing a stable operating environment for the installation and removal of the battery pack. The battery positioning unit can achieve positioning between the battery swapping platform and the battery pack, facilitating the installation and removal of the battery pack. The two second drive units drive the vehicle positioning unit and the battery positioning unit to move along the second direction, respectively, so that the movement of the vehicle positioning unit and the battery positioning unit is both independent and coordinated, thereby achieving precise positioning of the battery swapping platform.

[0024] Preferably, each of the second drive units includes a second drive motor and a second lead screw. One end of the second lead screw is connected to the power output end of the second drive motor, and the other end of the second lead screw is mounted in the receiving groove through a second mounting seat. A second connecting block is sleeved on the second lead screw, and each of the second connecting blocks is connected to the vehicle positioning unit and the battery positioning unit respectively.

[0025] In this solution, the second drive motor can drive the second lead screw to rotate, and the second connecting block is sleeved on the second lead screw, converting the rotational motion of the second lead screw into linear motion of the vehicle positioning part and the battery positioning part connected to it along the axial direction of the second lead screw, thus ensuring the moving efficiency and smoothness of the vehicle positioning part and the battery positioning part.

[0026] Preferably, the first guide is a slide rail, and both the vehicle positioning part and the battery positioning part are provided with sliders at their bottoms, with the sliders of both the vehicle positioning part and the battery positioning part slidably disposed on the first guide.

[0027] In this solution, the sliding cooperation between the slide rail and the slider reduces the frictional resistance experienced by the vehicle positioning unit and the battery positioning unit during their movement on the first guide, resulting in smoother movement and improved movement efficiency. The shared use of the first guide by the vehicle positioning unit and the battery positioning unit simplifies the structure and reduces costs. The use of the same slide rail as the movement reference further enhances the relative positioning accuracy between the two units.

[0028] Preferably, in the second direction, at least two sliders are provided at the bottom of the vehicle positioning part and the bottom of the battery positioning part, respectively, and the two sliders of the vehicle positioning part are located between the two sliders of the battery positioning part.

[0029] In this solution, along the second direction, i.e. along the guiding direction of the first guide, at least two sliders are provided at the bottom of the vehicle positioning part and the bottom of the battery positioning part, respectively, which can make the movement of the vehicle positioning part and the battery positioning part more stable; the two sliders of the vehicle positioning part are located between the two sliders of the battery positioning part, so that the vehicle positioning part and the battery positioning part are independent of each other and do not affect each other during the movement of the shared first guide.

[0030] Preferably, the height of the slider of the vehicle positioning part is lower than the height of the slider of the battery positioning part, so that at least a portion of the vehicle positioning part is located below the battery positioning part.

[0031] In this solution, since the vehicle positioning unit and the battery positioning unit share the first guide unit, and the two sliders of the vehicle positioning unit are located between the two sliders of the battery positioning unit, the height of the slider of the vehicle positioning unit is set to be lower than the height of the slider of the battery positioning unit, so that the vehicle positioning unit is lower than the battery positioning unit in the height direction, which facilitates the vehicle positioning unit and the battery positioning unit to move separately in the second direction without interfering with each other.

[0032] Preferably, the moving part has sliding parts at both ends along the second direction, the sliding parts are disposed on the lower surface of the moving part, and the supporting part has a second guide part extending along the first direction, the sliding parts being used to slide along the second guide part.

[0033] In this solution, the sliding cooperation between the sliding part and the second guide part reduces the frictional resistance experienced by the moving part during movement, thereby improving the moving efficiency and stability of the moving part. The movement of the moving part drives the vehicle positioning part and the battery positioning part to move along the first direction, which improves the adjustment range and accuracy of the battery swapping platform positioning, and can be adapted to more vehicle models and more battery pack specifications.

[0034] Preferably, the bottom of the movable part extends downward and protrudes, and the bottom of the movable part is lower than the surface of the support part.

[0035] In this design, the bottom of the moving part protrudes downward to form a receiving groove, which in turn accommodates the second drive part. The bottom of the moving part is lower than the surface of the support part, which can reduce the height of the moving part relative to the support part, thereby reducing the height of the battery mounting part relative to the support part. This makes the structure of the entire battery swapping platform more compact and relatively lower, which is beneficial for adapting to more low-chassis vehicle models.

[0036] Preferably, the vehicle positioning unit is connected to a battery swapping positioning mechanism and / or an unlocking mechanism. The battery swapping positioning mechanism is used to position the vehicle positioning unit with the electric vehicle, and the unlocking mechanism is used to unlock the battery pack on the electric vehicle.

[0037] In this solution, the battery positioning mechanism on the vehicle positioning unit can be matched with the vehicle-side positioning mechanism on the electric vehicle to prevent relative displacement between the battery swapping platform and the electric vehicle during the battery pack installation and removal process, thereby ensuring the positioning accuracy of the battery pack and improving the installation and removal efficiency of the battery pack; the unlocking mechanism on the vehicle positioning unit can directly or indirectly act on the locking mechanism on the electric vehicle to unlock the battery pack.

[0038] Preferably, the vehicle positioning part is disposed between the battery positioning part and the moving part in the height direction, the vehicle positioning part includes an exposed area, the exposed area is exposed on the horizontal projection of the battery positioning part, and the battery swapping positioning mechanism and / or the unlocking mechanism is located in the exposed area.

[0039] In this design, the vehicle positioning unit is offset from the battery positioning unit and the moving unit in the height direction, which facilitates the separate movement of the three without interference. Furthermore, the projections of the three on the horizontal plane can partially overlap, saving the overall space occupied by the battery swapping platform in the horizontal projection. At the same time, the exposed area of ​​the vehicle positioning unit provides clearance for the battery swapping positioning mechanism and the unlocking mechanism, allowing the battery swapping positioning mechanism to act on the electric vehicle and the unlocking mechanism to act on the locking mechanism that fixes the battery pack, without being obstructed by the battery positioning unit above the battery swapping positioning unit.

[0040] Preferably, the vehicle positioning part has a receiving notch, and the bottom of the battery positioning part has a third connecting block connected to the second driving part. The receiving notch is used for the third connecting block to pass through and connect to the second driving part.

[0041] In this solution, the vehicle positioning unit and the battery positioning unit share the first guide unit, and the second drive unit that drives the two to move is located in the receiving groove. The battery positioning unit located above the vehicle positioning unit needs to be connected to the second drive unit below the vehicle positioning unit. The receiving notch provides clearance for this connection. The third connecting block connects the battery positioning unit and the second drive unit together, so that the battery mounting unit can move in the second direction under the drive of the second drive unit.

[0042] Preferably, the battery positioning part includes an upper plate, and the upper plate is provided with a battery positioning mechanism, which is used to position the battery pack.

[0043] In this design, the upper plate facilitates the battery swapping platform in supporting the battery pack, and the battery positioning mechanism facilitates the positioning of the battery pack, thereby ensuring the stability of the battery pack during the movement and lifting of the battery pack by the battery swapping platform.

[0044] Preferably, the upper plate has an exposed notch on one side in the first direction, the upper plate is located above the vehicle positioning part in the height direction, the vehicle positioning part is connected to a battery swapping positioning mechanism and / or an unlocking mechanism, and the battery swapping positioning mechanism and / or the unlocking mechanism are exposed in the exposed notch in the horizontal projection direction.

[0045] In this design, the upper plate is located above the vehicle positioning section. The exposed notch on the upper plate is designed to provide clearance for the battery swapping positioning mechanism and the unlocking mechanism on the vehicle positioning section, so that the battery swapping positioning mechanism can act on the electric vehicle and the unlocking mechanism can act on the locking structure that fixes the battery pack, without being obstructed by the battery positioning section above the battery swapping positioning section.

[0046] Preferably, the upper plate is provided with a plurality of elastic floating components, which are used to elastically support the battery pack to adjust the tilt of the battery pack relative to the chassis of the electric vehicle.

[0047] In this solution, the battery pack is supported by multiple elastic floating components, which allows the battery swapping platform to adaptively adjust according to the tilt of the battery pack. This enables the floating disassembly and installation of the battery pack, avoiding over-positioning that could cause difficulties in disassembly and installation or battery swapping failure. It also prevents the battery pack from being subjected to hard impacts when it comes into contact with the locking mechanism on the electric vehicle.

[0048] Preferably, the battery positioning part further includes a battery tray, which is mounted on the upper plate by the elastic floating component, and the battery tray avoids the battery positioning mechanism, the battery swapping positioning mechanism and the unlocking mechanism in the first direction.

[0049] In this solution, the battery pack is supported by a battery tray, which improves the stability of the battery pack during movement. The battery tray is elastically connected to the upper plate through an elastic floating component, so that the battery pack on the battery tray is in a flexible bearing state, avoiding hard collisions when the battery pack is placed on the battery tray. The battery tray also provides clearance for the battery positioning mechanism, the battery swapping positioning mechanism and the unlocking structure, so as to avoid interference with other components of the battery swapping platform.

[0050] Preferably, the vehicle positioning unit includes a first vehicle positioning unit and a second vehicle positioning unit, and the battery positioning unit includes a first battery positioning unit and a second battery positioning unit. The first vehicle positioning unit and the first battery positioning unit are disposed on the moving unit, and the first driving unit is used to drive the moving unit and move the first vehicle positioning unit and the first battery positioning unit along the first direction.

[0051] In this solution, the battery swapping platform is equipped with two vehicle positioning units, which enhances the positioning between the battery swapping platform and the electric vehicle. The positions of the second vehicle positioning unit and the second battery positioning unit are fixed, while the first vehicle positioning unit and the first battery positioning unit can move along the first direction with the moving plate, thereby improving the position adjustment range and positioning accuracy of the battery swapping platform and enabling it to adapt to more vehicle models and more battery pack specifications.

[0052] Preferably, the moving part includes a first moving part and a second moving part, the first vehicle positioning part and the first battery positioning part are disposed on the first moving part, the second vehicle positioning part and the second battery positioning part are disposed on the second moving part, and the first driving part simultaneously drives the first moving part and the second moving part to move along the first direction.

[0053] In this solution, the combination of two sets of moving parts, vehicle positioning parts, and battery positioning parts forms two moving systems. This facilitates the adjustment of the tilt angle of the battery swapping platform when it comes into contact with the battery pack, making the lifting and movement of the battery pack by the battery swapping platform more flexible. Moreover, compared with a single integrated moving system, the two moving systems reduce the space occupied by the moving parts, vehicle positioning parts, and battery positioning parts. The gap between the two moving systems facilitates the assembly and maintenance of the moving parts, vehicle positioning parts, and battery positioning parts.

[0054] A battery swapping device, the battery swapping device including the battery swapping platform described above.

[0055] In this solution, the battery swapping equipment can initially locate the battery pack at the installation / removal position on the electric vehicle, and then the battery swapping platform completes the precise positioning of the battery pack. The battery swapping platform allows the battery swapping equipment to adjust its position within the planes of the first and second directions, improving the positioning adjustment range and accuracy of the equipment, and enabling it to adapt to more vehicle models and battery pack specifications.

[0056] Preferably, the battery swapping equipment further includes a traveling mechanism and a base frame, the battery swapping platform is disposed on the base frame, and the traveling mechanism is used to drive the base frame to move along a preset track.

[0057] In this design, the base frame provides support for the battery swapping platform, ensuring its stability during movement. The walking mechanism can drive the base frame to move, thereby moving the battery swapping platform to a preset position, facilitating the installation and removal of battery packs on the battery swapping platform.

[0058] Preferably, the battery swapping equipment further includes a lifting mechanism for driving the support unit to move up and down in the vertical direction.

[0059] In this solution, the battery swapping equipment needs to be positioned with the battery pack not only on the horizontal plane, but also vertically. The lifting mechanism can adjust the vertical distance between the battery swapping equipment and the electric vehicle, facilitating the battery swapping equipment to install, remove, and move the battery pack.

[0060] A battery swapping station, the battery swapping station comprising the aforementioned battery swapping equipment.

[0061] In this solution, the battery swapping station achieves precise positioning of the battery pack along the first and second directions through the battery swapping equipment. This avoids the shortcomings of traditional positioning methods, where the battery swapping equipment can only move along a single linear direction and has a small positioning adjustment range. It improves the positioning adjustment range and positioning accuracy of the battery swapping equipment, enabling the battery swapping station to adapt to more vehicle models and more battery pack specifications.

[0062] The positive and progressive effects of this invention are as follows:

[0063] In this invention, the support unit serves as the supporting structure of the battery swapping platform, providing stable support for the battery installation unit and ensuring sufficient stability of the battery swapping platform during battery pack installation and removal. The battery installation unit can remove the depleted battery pack from the electric vehicle and install the fully charged battery pack onto the electric vehicle. The drive unit can drive the battery installation unit to move along a first direction and a second direction that are perpendicular to each other. This allows the battery installation unit to adjust its position within the plane containing the first and second directions when positioning itself with the battery pack on the electric vehicle. This avoids the shortcomings of traditional positioning methods, where the battery swapping platform can only move along a single linear direction and has a small positioning adjustment range. It improves the positioning adjustment range and positioning accuracy of the battery swapping platform and can adapt to more vehicle models and more battery pack specifications.

[0127] 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.

[0128] like Figures 1 to 12 As shown, this embodiment provides a battery swapping platform 101 for installing and removing battery packs on electric vehicles. The battery swapping platform 101 includes a support part 1, a battery mounting part 2, and a drive part 3. The battery mounting part 2 is disposed on the support part 1 and is used for installing and removing battery packs on electric vehicles. The drive part 3 is used to drive the battery mounting part 2 to move relative to the support part 1 along a first direction and a second direction. The first direction is perpendicular to the second direction.

[0129] The support part 1 serves as the support structure for the battery swapping platform 101, providing stable support for the battery mounting part 2 and ensuring sufficient stability of the battery swapping platform 101 during battery pack installation and removal. The battery mounting part 2 can remove the depleted battery pack from the electric vehicle and install the fully charged battery pack onto it. The drive part 3 can drive the battery mounting part 2 to move along a first direction and a second direction that are perpendicular to each other. This allows the battery mounting part 2 to adjust its position within the plane containing the first and second directions when positioning itself with the battery pack on the electric vehicle. This avoids the shortcomings of traditional positioning methods where the battery swapping platform 101 can only move along a single linear direction and has a small positioning adjustment range. It improves the positioning adjustment range and positioning accuracy of the battery swapping platform 101, and can adapt to more vehicle models and battery pack specifications. Specifically, in this embodiment, the first direction is the direction of the width of the electric vehicle body, and the second direction is the direction along the length of the electric vehicle body.

[0130] In this embodiment, the driving unit 3 includes a first driving unit 31 and a second driving unit 32. The first driving unit 31 is used to drive the battery mounting unit 2 to move along a first direction, and the second driving unit 32 is used to drive the battery mounting unit 2 to move along a second direction. By driving the battery mounting unit 2 along the first direction and the second direction respectively by the first driving unit 31 and the second driving unit 32, the two driving units 3 are independent and flexible in driving, while also being able to drive in coordination. This allows the battery swapping platform 101 to be accurately positioned in the plane containing the first and second directions, improving the adjustment range of the battery swapping platform 101's positioning, and thus facilitating the positioning, unlocking, and moving of the battery pack.

[0131] In this embodiment, the battery swapping platform 101 further includes a moving part 4. The battery mounting part 2 is mounted on the support part 1 via the moving part 4. The first driving part 31 drives the moving part 4 to move along a first direction on the support part 1. By driving the moving part 4 to move along the first direction via the first driving part 31, the battery mounting part 2 on the moving part 4 is moved along the first direction. The moving part 4 provides a moving platform for the battery mounting part 2, thereby making the movement of the battery mounting part 2 along the first direction more stable.

[0132] In this embodiment, the first driving unit 31 includes a first driving motor 311 and a first lead screw 312. One end of the first lead screw 312 is connected to the power output end of the first driving motor 311, and the other end of the first lead screw 312 is mounted on the support unit 1 via a first mounting base 313. A first connecting block 314 is sleeved on the first lead screw 312 and is connected to the moving unit 4. The first driving motor 311 drives the first lead screw 312 to rotate. The first connecting block 314 is sleeved on the first lead screw 312 and converts the rotational motion of the first lead screw 312 into linear motion of the moving unit 4 connected to it along the axial direction of the first lead screw 312, ensuring the moving efficiency and smoothness of the moving unit 4.

[0133] In this embodiment, the moving part 4 is provided with a first guide part 51 extending along the second direction. The first guide part 51 is used to guide the battery mounting part 2 to move along the second direction. The first guide part 51 ensures that the battery mounting part 2 does not deviate from the preset direction during the movement along the second direction, thus ensuring the accuracy of the movement of the battery mounting part 2 and improving the movement efficiency of the battery mounting part 2.

[0134] In this embodiment, the moving part 4 has a recessed receiving groove 41 extending downward from its upper surface. The receiving groove 41 is used to accommodate the second driving part 32, which is connected to the battery mounting part 2. The second driving part 32 is used to drive the battery mounting part 2 to move along the first guide part 51. The recessed receiving groove 41 of the moving part 4 provides installation space for the second driving part 32 and reduces the height of the entire battery swapping platform 101, making the structure of the entire battery swapping platform 101 more compact and easier to adapt to more vehicles with lower chassis height. The second driving part 32 can drive the battery mounting part 2 to move along the first guide part 51 on the moving part 4, realizing the movement of the battery mounting part 2 in the second direction, which facilitates the positioning of the battery mounting part 2 with the battery pack on the electric vehicle.

[0135] In this embodiment, the battery mounting part 2 includes a vehicle positioning part 21 and a battery positioning part 22. The vehicle positioning part 21 is mounted on the support part 1 and is used for positioning with the electric vehicle. The battery positioning part 22 is mounted on the support part 1 and is used for positioning with the battery pack. Two second driving parts 32 are provided in the receiving slot 41. The two second driving parts 32 are used to drive the vehicle positioning part 21 and the battery positioning part 22 to move along the first guide part 51. The vehicle positioning part 21 can realize the positioning between the battery swapping platform 101 and the electric vehicle, so that there is no relative displacement between the battery swapping platform 101 and the electric vehicle during the battery swapping process, providing a stable operating environment for the installation and removal of the battery pack. The battery positioning part 22 can realize the positioning between the battery swapping platform 101 and the battery pack, which facilitates the installation and removal of the battery pack. The two second driving parts 32 drive the vehicle positioning part and the battery positioning part 22 to move along the second direction, so that the movement of the vehicle positioning part 21 and the battery positioning part 22 is both independent and coordinated, thereby realizing the precise positioning of the battery swapping platform 101.

[0136] In this embodiment, each second drive unit 32 includes a second drive motor 321 and a second lead screw 322. One end of the second lead screw 322 is connected to the power output end of the second drive motor 321, and the other end of the second lead screw 322 is mounted in the receiving groove 41 through a second mounting base 323. A second connecting block 324 is sleeved on the second lead screw 322, and each second connecting block 324 is connected to the vehicle positioning unit 21 and the battery positioning unit 22 respectively. The second drive motor 321 can drive the second lead screw 322 to rotate. The second connecting block 324 is sleeved on the second lead screw 322 and converts the rotational motion of the second lead screw 322 into linear motion of the vehicle positioning unit 21 and the battery positioning unit 22 connected to it along the axial direction of the second lead screw 322, ensuring the moving efficiency and smoothness of the vehicle positioning unit 21 and the battery positioning unit 22.

[0137] In this embodiment, the first guide portion 51 is a slide rail, and both the vehicle positioning portion 21 and the battery positioning portion 22 are provided with sliders 52 at their bottoms. The sliders 52 of both the vehicle positioning portion 21 and the battery positioning portion 22 are slidably disposed on the first guide portion 51. Through the sliding cooperation of the slide rail and the sliders 52, the frictional resistance encountered by the vehicle positioning portion 21 and the battery positioning portion 22 during their movement on the first guide portion 51 is reduced, resulting in smoother movement and improved movement efficiency. The vehicle positioning portion 21 and the battery positioning portion 22 share the first guide portion 51, which simplifies the structure and reduces costs. The fact that both use the same slide rail as a movement reference results in higher relative positioning accuracy between them.

[0138] In this embodiment, in the second direction, two sliders 52 are respectively provided at the bottom of the vehicle positioning part 21 and the bottom of the battery positioning part 22, with the two sliders 52 of the vehicle positioning part 21 located between the two sliders 52 of the battery positioning part 22. Along the second direction, i.e., along the guiding direction of the first guide part 51, the provision of two sliders 52 at the bottom of the vehicle positioning part 21 and the bottom of the battery positioning part 22 makes the movement of the vehicle positioning part 21 and the battery positioning part 22 smoother. The location of the two sliders 52 of the vehicle positioning part 21 between the two sliders 52 of the battery positioning part 22 ensures that the vehicle positioning part 21 and the battery positioning part 22 move independently of each other during their shared movement along the first guide part 51, without affecting each other. In other embodiments, the number of sliders 52 at the bottom of the vehicle positioning part 21 and the bottom of the battery positioning part 22 is not limited to two; it can also be one, three, or more.

[0139] In this embodiment, the height of the slider 52 of the vehicle positioning part 21 is lower than the height of the slider 52 of the battery positioning part 22, so that at least a portion of the vehicle positioning part 21 is located below the battery positioning part 22. Since the vehicle positioning part 21 and the battery positioning part 22 share the first guide part 51, and the two sliders 52 of the vehicle positioning part 21 are located between the two sliders 52 of the battery positioning part 22, the height of the slider 52 of the vehicle positioning part 21 is set lower than the height of the slider 52 of the battery positioning part 22, so that the vehicle positioning part 21 is lower than the battery positioning part 22 in the height direction, which facilitates the vehicle positioning part 21 and the battery positioning part 22 to move separately in the second direction without interfering with each other.

[0140] In this embodiment, the moving part 4 has sliding parts 53 at both ends along the second direction. The sliding parts 53 are located on the lower surface of the moving part 4, and the support part 1 has a second guide part 54 extending along the first direction. The sliding parts 53 are used to slide along the second guide part 54. Through the sliding cooperation of the sliding parts 53 and the second guide part 54, the frictional resistance experienced by the moving part 4 during movement is reduced, improving the moving efficiency and smoothness of the moving part 4. The movement of the moving part 4 drives the vehicle positioning part 21 and the battery positioning part 22 to move along the first direction, improving the adjustment range and accuracy of the battery swapping platform 101 positioning, and enabling it to adapt to more vehicle models and more battery pack specifications. Specifically, in this embodiment, the moving part 4 has two sliding parts 53 on each side along the second direction to make the movement of the moving part 4 smoother. In other embodiments, the number of sliding parts 53 can be other values ​​and is not limited to this embodiment.

[0141] In this embodiment, the bottom of the movable part 4 extends downward and protrudes, and the bottom of the movable part 4 is lower than the surface of the support part 1. The downward protrusion of the bottom of the movable part 4 forms a receiving groove 41, which in turn accommodates the second drive part 32. The fact that the bottom of the movable part 4 is lower than the surface of the support part 1 reduces the height of the movable part 4 relative to the support part 1, thereby reducing the height of the battery mounting part 2 relative to the support part 1. This makes the structure of the entire battery swapping platform 101 more compact and its height relatively lower, which is beneficial for adapting to more low-chassis vehicle models.

[0142] In this embodiment, the vehicle positioning unit 21 is connected to a battery swapping positioning mechanism 211 and an unlocking mechanism 212. The battery swapping positioning mechanism 211 is used to position the vehicle positioning unit 21 relative to the electric vehicle, and the unlocking mechanism 212 is used to unlock the battery pack on the electric vehicle. The battery positioning mechanism 223 on the vehicle positioning unit 21 can match the vehicle-side positioning mechanism on the electric vehicle, preventing relative displacement between the battery swapping platform 101 and the electric vehicle during the battery pack installation and removal process, thereby ensuring the positioning accuracy of the battery pack and improving the installation and removal efficiency of the battery pack. The unlocking mechanism 212 on the vehicle positioning unit 21 can directly or indirectly act on the locking mechanism on the electric vehicle to unlock the battery pack. In other embodiments, the vehicle positioning unit 21 may also be equipped with only one of the battery swapping positioning mechanism 211 or the unlocking mechanism 212.

[0143] In this embodiment, the vehicle positioning unit 21 is positioned vertically between the battery positioning unit 22 and the moving unit 4. The vehicle positioning unit 21 includes an exposed area 213, which is exposed above the battery positioning unit 22 in a horizontal projection. The battery swapping positioning mechanism 211 and the unlocking mechanism 212 are located in the exposed area 213. The vehicle positioning unit 21 is offset vertically from the battery positioning unit 22 and the moving unit 4, facilitating their separate movement without interference. Furthermore, the projections of the three components on the horizontal plane can partially overlap, saving the overall space occupied by the battery swapping platform 101 in a horizontal projection. At the same time, the exposed area 213 of the vehicle positioning unit 21 provides clearance for the battery swapping positioning mechanism 211 and the unlocking mechanism 212, allowing the battery swapping positioning mechanism 211 to act on the electric vehicle and the unlocking mechanism 212 to act on the locking mechanism that secures the battery pack, without being obstructed by the battery positioning unit 22 above the battery positioning unit.

[0144] In this embodiment, the vehicle positioning part 21 has a receiving notch 214, and the bottom of the battery positioning part 22 has a third connecting block 221 connected to the second driving part 32. The receiving notch 214 is used for the third connecting block 221 to pass through and connect to the second driving part 32. The vehicle positioning part 21 and the battery positioning part 22 share the first guide part 51. The second driving part 32 that drives the movement of both is provided in the receiving groove 41. The battery positioning part 22 located above the vehicle positioning part 21 needs to be connected to the second driving part 32 below the vehicle positioning part 21. The receiving notch 214 provides clearance for this connection. The third connecting block 221 connects the battery positioning part 22 and the second driving part 32 together, so that the battery mounting part 2 can move in the second direction under the drive of the second driving part 32.

[0145] In this embodiment, the battery positioning unit 22 includes an upper plate 222, which is provided with a battery positioning mechanism 223 for positioning the battery pack. The upper plate 222 facilitates the battery swapping platform 101 in supporting the battery pack, and the battery positioning mechanism 223 facilitates the positioning of the battery pack, so as to maintain the stability of the battery pack during the movement and lifting of the battery pack by the battery swapping platform 101.

[0146] In this embodiment, the upper plate 222 has an exposed notch 224 on one side in the first direction. The upper plate 222 is located above the vehicle positioning part 21 in the height direction. The vehicle positioning part 21 is connected to a battery swapping positioning mechanism 211 and an unlocking mechanism 212. The battery swapping positioning mechanism 211 and the unlocking mechanism 212 are exposed in the exposed notch 224 in the horizontal projection direction. The upper plate 222 is located above the vehicle positioning part 21. The exposed notch 224 of the upper plate 222 is set to leave clearance space for the battery swapping positioning mechanism 211 and the unlocking mechanism 212 on the vehicle positioning part 21, so that the battery swapping positioning mechanism 211 can act on the electric vehicle and the unlocking mechanism 212 can act on the locking structure that fixes the battery pack, without being blocked by the battery positioning part 22 above the battery swapping positioning part.

[0147] In this embodiment, the upper plate 222 is provided with multiple elastic floating components 225. The elastic floating components 225 are used to elastically support the battery pack to adjust the tilt of the battery pack relative to the chassis of the electric vehicle. By supporting the battery pack with multiple elastic floating components 225, the battery swapping platform 101 can adaptively adjust according to the tilt of the battery pack, enabling floating disassembly and installation of the battery pack. This avoids over-positioning that could cause difficulties in disassembly and installation, or battery swapping failure, and also prevents the battery pack from being subjected to hard impacts when it comes into contact with the locking mechanism on the electric vehicle.

[0148] In this embodiment, the battery positioning unit 22 further includes a battery tray 226. The battery tray 226 is mounted on the upper plate 222 via an elastic floating component 225. The battery tray 226 avoids the battery positioning mechanism 223, the battery swapping positioning mechanism 211, and the unlocking mechanism 212 in a first direction. By supporting the battery pack, the stability of the battery pack during movement is improved. The battery tray 226 is elastically connected to the upper plate 222 via the elastic floating component 225, so that the battery pack on the battery tray 226 is in a flexible bearing state, avoiding hard collisions during the placement of the battery pack on the battery tray 226. The battery tray 226 also provides clearance for the battery positioning mechanism 223, the battery swapping positioning mechanism 211, and the unlocking mechanism, avoiding interference with other components of the battery swapping platform 101.

[0149] In this embodiment, the vehicle positioning unit 21 includes a first vehicle positioning unit and a second vehicle positioning unit, and the battery positioning unit 22 includes a first battery positioning unit and a second battery positioning unit. The first vehicle positioning unit and the first battery positioning unit are disposed on the moving unit 4. The first driving unit 31 is used to drive the moving unit 4 and move the first vehicle positioning unit and the first battery positioning unit along a first direction. The battery swapping platform 101 is provided with two vehicle positioning units 21, which enhances the positioning between the battery swapping platform 101 and the electric vehicle. The positions of the second vehicle positioning unit and the second battery positioning unit are fixed, while the first vehicle positioning unit and the first battery positioning unit can move along the first direction with the moving plate, thereby improving the position adjustment range and positioning accuracy of the battery swapping platform 101 and enabling it to adapt to more vehicle models and more battery pack specifications.

[0150] In this embodiment, the moving part 4 includes a first moving part and a second moving part. A first vehicle positioning part and a first battery positioning part are disposed on the first moving part, and a second vehicle positioning part and a second battery positioning part are disposed on the second moving part. The first driving part 31 simultaneously drives the first moving part and the second moving part to move along a first direction. The combination of the two sets of moving parts 4, the vehicle positioning part 21 and the battery positioning part 22 forms two sets of moving systems, which facilitates the adjustment of the tilt angle of the battery swapping platform 101 when contacting the battery pack, making the lifting and movement of the battery pack by the battery swapping platform 101 more flexible. Moreover, compared with a single integral moving system, the two sets of moving systems reduce the space occupied by the moving parts 4, the vehicle positioning part 21 and the battery positioning part 22. The gap between the two sets of moving systems facilitates the assembly and maintenance of the moving parts 4, the vehicle positioning part 21 and the battery positioning part 22.

[0151] like Figures 13 to 18 As shown, this embodiment also provides a battery swapping device 100, which includes the aforementioned battery swapping platform 101. The battery swapping device 100 can initially position itself relative to the battery pack's mounting / removing location on the electric vehicle, and then the battery swapping platform 101 completes the precise positioning of the battery pack. The battery swapping platform 101 allows the battery swapping device 100 to adjust its position within the plane containing the first and second directions, improving the positioning adjustment range and accuracy of the battery swapping device 100, and enabling it to adapt to more vehicle models and battery pack specifications.

[0152] In this embodiment, the battery swapping device 100 further includes a traveling mechanism 102 and a base frame 103. The battery swapping platform 101 is mounted on the base frame 103, and the traveling mechanism 102 drives the base frame 103 to move along a preset track. The base frame 103 provides support for the battery swapping platform 101, ensuring the stability of the battery swapping platform 101 during movement. The traveling mechanism 102 can drive the base frame 103 to move, thereby moving the battery swapping platform 101 to a preset position, facilitating the battery swapping platform 101 to install and remove battery packs.

[0153] In this embodiment, the battery swapping device 100 also includes a lifting mechanism 104, which drives the support unit 1 to move up and down in the vertical direction. The battery swapping device 100 needs to be positioned with the battery pack not only horizontally but also vertically. The lifting mechanism 104 can adjust the vertical distance between the battery swapping device and the electric vehicle, facilitating the battery swapping device 100's disassembly, assembly, and movement of the battery pack.

[0154] Specifically, in this embodiment, the lifting mechanism 104 includes a third drive motor 1041, a transmission shaft 1042, a drive wheel 1043, and a cam assembly 1044. The cam assembly 1044 includes a driven wheel 1045, a cam body 1046, and a connecting part 1047. The driven wheel 1045 is connected to the cam body 1046 and the driven wheel 1045 and the cam body 1046 are coaxially arranged. The connecting part 1047 is connected to the support part 1 and has a groove 1048. The protrusion of the cam body 1046 is disposed in the groove 1048. The main lifting process is as follows: the third drive motor 1041 drives the transmission shaft 1042 to rotate, the transmission shaft 1042 drives the drive wheel 1043 to rotate, the drive wheel 1043 drives the driven wheel 1045 of the cam assembly 1044 to rotate, the driven wheel 1045 drives the protrusion of the cam body 1046 to slide in the slide groove 1048, thereby driving the connecting part 1047 to move in the vertical direction, so as to realize the lifting of the support part 1.

[0155] This embodiment also provides a battery swapping station, which includes the aforementioned battery swapping equipment 100. The battery swapping station achieves precise positioning of the battery pack along a first direction and a second direction through the battery swapping equipment 100. This avoids the shortcomings of traditional positioning methods where the battery swapping equipment 100 can only move along a single linear direction and has a small positioning adjustment range. It improves the positioning adjustment range and positioning accuracy of the battery swapping equipment 100, enabling the battery swapping station to adapt to more vehicle models and more battery pack specifications.
