Description

Battery swapping stations and battery swapping methods Technical Field

[0001] This application relates to the field of battery swapping technology, and more specifically, to a battery swapping station and a battery swapping method. Background Technology

[0002] With technological advancements, the battery industry has developed rapidly, and the market share and usage frequency of electric devices are increasing. Electric vehicles, such as electric cars, are gradually appearing in various application scenarios. At the same time, to improve the convenience of electric vehicles, battery swapping stations for rapid battery replacement have emerged in the market.

[0003] Because vehicles come into contact with various environments during operation, foreign objects may adhere to the battery surface. How to remove these foreign objects is a problem that urgently needs to be solved in the industry. Summary of the Invention

[0004] This application provides a battery swapping station and a battery swapping method that can clean foreign matter from the surface of a battery device.

[0005] In a first aspect, embodiments of this application provide a battery swapping station, comprising a battery swapping platform, a storage device, a battery swapping unit, a transfer device, and a cleaning device. The battery swapping platform is used to carry a vehicle. The storage device includes multiple storage compartments, each used to store and charge a battery device. The battery swapping unit is used to remove the battery device from the vehicle and to install the battery device stored in the storage compartment onto the vehicle. The transfer device is used to transfer the battery device between the storage device and the battery swapping unit. The cleaning device is disposed on the transfer device and is used to clean foreign matter from the surface of the battery device.

[0006] In the above technical solution, the cleaning device can remove foreign objects from the surface of the battery pack, reducing the risk of corrosion and interference with other components during battery pack removal and installation, thus lowering the risk of battery swapping failure. The cleaning device can also clean the battery pack during the transfer process, saving cleaning time and optimizing the battery swapping cycle to improve efficiency. Furthermore, the cleaning device on the transfer device can clean all battery packs removed from the vehicle, simplifying the structure of the battery swapping station and reducing its cost.

[0007] In some embodiments, the transfer device includes a frame and a support mechanism movably disposed on the frame, the support mechanism being used to support the battery device, and a cleaning device located above the support mechanism. The support mechanism is configured to move the battery device along a first direction, such that the cleaning device cleans the battery device during the movement of the battery device, the first direction being perpendicular to the vertical direction.

[0008] During the use of the battery device, foreign matter easily accumulates on its upper surface. Placing the cleaning device on top of the support mechanism helps clean this debris. The support mechanism can move the battery device along a first direction to pick up and place it. The cleaning device and the battery device can move relative to each other in the first direction to clean the battery device; the cleaning device can clean the battery device during the pick-up and drop process, saving cleaning time and improving battery swapping efficiency. The support mechanism provides power for the relative movement between the battery device and the cleaning device, thus eliminating the need for a separate power mechanism for the cleaning device and simplifying the structure of both the transfer and cleaning devices.

[0009] In some embodiments, the support mechanism is configured to move relative to the frame between a first position and a second position, the first and second positions being spaced apart along a first direction. The cleaning device is positioned between the first and second positions in the first direction to clean the battery device as it passes through. When the support mechanism moves between the first and second positions, the battery device can pass entirely through the cleaning device, which helps to increase the cleaning area of ​​the cleaning device and improve the cleaning effect.

[0010] In some embodiments, the first position is located inside the rack, and the second position is located outside the rack. When the carrier mechanism is in the second position, it can extend to the outside of the rack to facilitate gripping or placing the battery device; when the carrier mechanism is in the first position, it can move the battery device into the rack, thereby reducing the risk of interference between the battery device and the carrier mechanism and other components during the movement of the transfer device.

[0011] In some embodiments, the cleaning device includes a cleaning component and a rotating shaft connected to a frame. The cleaning component is rotatably connected to the rotating shaft, and the axis of the rotating shaft is parallel to a second direction, wherein the second direction, the first direction, and the vertical direction are perpendicular to each other. At least a portion of the cleaning component is located below the rotating shaft and positioned on the movement path of the battery device.

[0012] During the movement of the battery unit, the cleaning component can block foreign objects on the battery unit. When a small foreign object is blocked by the cleaning component, it will fall off under the action of the cleaning component as the battery unit moves. When there is a larger foreign object on the battery unit, the larger foreign object may be stuck by the protruding structure on the battery unit. In this case, the cleaning component can rotate around the pivot and pass over the larger foreign object, thus posing a risk of damage to the cleaning component and the battery unit. After passing over the larger foreign object, the cleaning component can drop back into position under the action of gravity and continue cleaning foreign objects in the area behind it.

[0013] In some embodiments, the cleaning component includes a connecting rod and a flexible component, the upper end of the connecting rod being rotatably connected to a pivot, and the flexible component being connected to the lower end of the connecting rod.

[0014] Using flexible components to clean the battery device reduces the risk of wear and tear during the cleaning process. The connecting rod has a certain weight and rigidity, preventing deformation or bending when foreign objects are blocked by the flexible component. The connecting rod restricts the movement of the flexible component, allowing it to effectively wipe the battery device and remove foreign objects from its surface. When larger foreign objects are stuck by protruding structures on the battery device, the connecting rod can rotate around its axis to allow the flexible component to pass over the larger object.

[0015] In some embodiments, the cleaning device further includes a detector for detecting the angle of rotation of the cleaning component. The detector can detect the angle of rotation of the cleaning component about a pivot axis to determine whether there are large foreign objects remaining on the surface of the battery device. If it is determined that there are large foreign objects remaining on the surface of the battery device, the battery swapping station can use other methods to remove the foreign objects.

[0016] In some embodiments, the cleaning device includes a cleaning component and a collection box. At least a portion of the cleaning component is disposed along the movement path of the battery device. The collection box has an opening on its upper side, the opening not exceeding the lower end of the cleaning component. In a second direction, the vertical projection of the cleaning component lies inside the vertical projection of the collection box; the second direction, the first direction, and the vertical direction are perpendicular to each other. During the movement of the battery device, the cleaning component can block foreign objects on the battery device; as the battery device moves, the foreign objects fall under the action of the cleaning component and fall into the collection box through the opening. The collection box can collect foreign objects to reduce their impact on the internal environment of the battery swapping station and reduce interference caused by foreign objects.

[0017] In some embodiments, two cleaning devices are provided on the same side of the frame along a first direction, and the two cleaning devices are spaced apart along a second direction, wherein the second direction, the first direction, and the vertical direction are perpendicular to each other. The two cleaning devices can clean both ends of the battery device along the second direction, which helps to increase the cleaning area of ​​the cleaning devices and improve the cleaning effect.

[0018] In some embodiments, the support mechanism is configured to be movable to both sides of the frame along a first direction. Cleaning devices are provided on both sides of the frame along the first direction. The cleaning devices located on both sides of the frame can clean the battery assembly, which helps to increase the cleaning area and improve the cleaning effect.

[0019] In some embodiments, the transfer device further includes a drive unit disposed on the frame. The drive unit includes a first drive member and a second drive member. The first drive member drives the carrier mechanism to move along a first direction, and the second drive member drives the carrier mechanism to move up and down in a vertical direction. The first drive member can drive the battery device through the carrier mechanism so that the battery device passes through the cleaning device. The second drive member provides power for the lifting and lowering of the carrier mechanism to facilitate the carrier mechanism in supporting or placing the battery device.

[0020] In some embodiments, the support mechanism and the cleaning device are configured to move up and down synchronously in the vertical direction. As the support mechanism moves up and down, the cleaning device moves up and down synchronously with it, enabling the cleaning device to clean the battery device placed on the support mechanism.

[0021] In some embodiments, the transfer device further includes a drive device, which includes a third drive member connected to the cleaning device and used to drive the cleaning device to rise and fall. By providing the third drive member, the rising and falling of the cleaning device can be controlled independently, thereby adapting to battery devices of different heights. In addition, the third drive member can also change the distance between the cleaning device and the support mechanism, thereby adjusting the friction between the cleaning device and the battery device and improving the cleaning effect.

[0022] In some embodiments, the battery swapping station further includes a buffer device comprising multiple buffer bits, each buffer bit for storing a battery device. The multiple buffer bits are used for transferring battery devices between the transfer device and the battery swapping device, and for transferring battery devices between the transfer device and the storage device. By setting multiple buffer bits, the time for the transfer device to transfer battery devices and the time for the battery swapping device to install and remove battery devices can partially overlap, which helps optimize the battery swapping cycle and improve battery swapping efficiency.

[0023] Secondly, embodiments of this application also provide a battery swapping method, which includes: driving a vehicle to a battery swapping platform; a battery swapping device removing the battery from the vehicle; a transfer device receiving the battery removed from the vehicle by the battery swapping device; a cleaning device cleaning foreign objects from the surface of the battery; and the transfer device placing the battery into a storage location of a storage device.

[0024] The cleaning device can remove foreign objects from the surface of the battery pack, reducing the risk of corrosion and interference with other components during battery assembly and disassembly, thus lowering the risk of battery swapping failure. The cleaning device can also clean the battery pack during the transfer process, saving cleaning time and optimizing the battery swapping cycle to improve efficiency.

[0025] In some embodiments, the step of the transfer device receiving the battery device removed from the vehicle by the battery swapping device includes: the carrying mechanism of the transfer device moving from a first position to a second position along a first direction and supporting the battery device removed from the vehicle by the battery swapping device.

[0026] The steps of the cleaning device for cleaning foreign objects from the surface of the battery device include: the carrying mechanism moves from a second position toward a first position, the battery device passes through the cleaning device, and the cleaning device cleans at least a portion of the upper surface of the battery device; after the carrying mechanism moves to the first position, the transfer device moves toward the storage device to a preset position; the carrying mechanism moves from the first position toward the second position, the battery device passes through the cleaning device, and the cleaning device cleans at least a portion of the upper surface of the battery device.

[0027] In this embodiment of the application, the battery device is cleaned twice during the transfer process, thereby improving the cleaning effect and reducing the risk of corrosion of the battery device. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0042] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0045] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0047] In the embodiments of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering.

[0048] With the development of new energy technologies, more and more devices are using battery devices. Taking vehicles as an example, when a vehicle's battery is depleted, it is usually replenished by connecting to a charging device. Charging takes a long time, affecting the user experience. Compared to charging, replacing the battery device can replenish the energy much faster.

[0049] During operation, vehicles come into contact with various environments, which can cause foreign objects such as dust, stones, coal, and coal powder to accumulate on the surface of the battery pack. Long-term adhesion of these foreign objects can corrode the battery pack, affecting its reliability and lifespan. Furthermore, accumulated foreign objects may interfere with the connection between the battery pack and the vehicle's chassis, impacting the efficiency of battery installation and removal, and increasing the risk of battery swapping failures.

[0050] In view of this, embodiments of this application provide a battery swapping station and a battery swapping method, which cleans the surface of the battery device during the battery swapping process by setting up a cleaning device, reducing foreign matter adhering to the surface of the battery device, reducing the risk of battery device corrosion, and improving battery swapping efficiency.

[0051] The battery swapping station and method disclosed in this application can be used, but are not limited to, for swapping vehicle batteries. The vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle; new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended vehicles, etc.

[0053] Referring to Figures 1 to 7, this application embodiment provides a battery swapping station, which includes a battery swapping platform 1, a storage device 2, and a battery swapping device 3. The battery swapping platform 1 is used to carry a vehicle 7. The storage device 2 includes a plurality of storage slots 21, each storage slot 21 being used to store a battery device 8 and to charge the battery device 8. The battery swapping device 3 is used to remove the battery device 8 from the vehicle 7 and to install the battery device 8 stored in the storage slot 21 onto the vehicle 7.

[0054] As an example, battery swapping stations can replace the battery devices of electric heavy-duty trucks, electric light-duty trucks, electric passenger cars, or other electric vehicles.

[0055] The battery swapping platform 1 is used to place the vehicle 7; after the vehicle 7 is placed on the battery swapping platform 1, the battery device 8 of the vehicle 7 can be replaced. The battery swapping platform 1 can be the ground or a support platform placed on the ground, etc.

[0056] As an example, the battery swapping platform 1 can be a fixed platform or a lifting platform. For example, the battery swapping platform 1 can lift the vehicle 7 placed on it.

[0057] Storage compartment 21 of storage device 2 can serve both to store battery device 8 and to charge battery device 8. As an example, battery device 8 removed from vehicle 7 can be stored in storage compartment 21, and storage compartment 21 can charge battery device 8; a fully charged battery device 8 located in another storage compartment 21 can be installed on the chassis of vehicle 7 to complete battery swapping.

[0058] One storage location 21 can store one battery device 8 or multiple battery devices 8. Optionally, one storage location 21 can store one battery device 8.

[0059] The battery swapping device 3 can be used to replace the battery device 8 of the vehicle 7.

[0060] As an example, the battery swapping station can replace the battery device 8 according to the following steps: I) After the vehicle 7 enters the battery swapping platform 1, the battery swapping device 3 can move to the underside of the vehicle 7 and remove the depleted battery device 8 from the chassis of the vehicle 7; II) The battery swapping device 3 transfers the depleted battery device 8 to a storage position 21 for charging and receives a fully charged battery device 8 stored in another storage position 21; III) The battery swapping device 3 moves the fully charged battery device 8 to the underside of the vehicle 7 and installs the fully charged battery device 8 onto the chassis; IV) The vehicle 7 leaves the battery swapping platform 1.

[0061] In some embodiments, the battery swapping station includes a transfer device 4 for transferring the battery device 8 between the storage device 2 and the battery swapping device 3.

[0062] The transfer device 4 can transfer the battery device 8 on the battery swapping device 3 to the storage device 2, or it can transfer the battery device 8 stored in the storage device 2 to the battery swapping device 3.

[0063] In some examples, after the battery swapping device 3 removes the battery device 8 from the chassis of the vehicle 7, the battery swapping device 3 transfers the battery device 8 to a set location; then, the transfer device 4 removes the battery device 8 and places it in a storage position 21 to charge the battery device 8.

[0064] The transfer device 4 can directly remove the battery device 8 from the battery swapping device 3. Alternatively, the battery swapping station also includes a buffer device 6, to which the battery swapping device 3 can transfer the battery device 8, while the transfer device 4 removes the battery device 8 from the buffer device 6.

[0065] In some examples, the transfer device 4 can remove a fully charged battery device 8 from a storage location 21 and then transfer the fully charged battery device 8 to a set location; then, the battery swapping device 3 removes the battery device 8 and installs the battery device 8 onto the chassis of the vehicle 7.

[0066] Optionally, the transfer device 4 can directly place the fully charged battery device 8 into the battery swapping device 3. Alternatively, the transfer device 4 can transfer the fully charged battery device 8 to the buffer device 6, and the battery swapping device 3 can remove the fully charged battery device 8 from the buffer device 6; alternatively, the battery swapping device 3 can first remove the fully charged battery device 8 that is pre-stored in the buffer device 6 and install the battery device 8 into the vehicle 7, and then the transfer device 4 can transfer another fully charged battery device 8 to the buffer device 6 for storage.

[0067] The structure of the transfer device 4 can be varied. For example, the transfer device 4 may include a robot, a palletizer, or other structures.

[0068] In some embodiments, the battery swapping platform 1 and the storage device 2 are arranged along a first direction X, which is perpendicular to the vertical direction Z.

[0069] In some embodiments, the transfer device 4 is disposed between the battery swapping platform 1 and the storage device 2 in the first direction X. In other embodiments, there are at least two storage devices 2, which are spaced apart along the first direction X; the transfer device 4 may be disposed between the two storage devices 2 in the first direction X.

[0070] In some embodiments, the battery swapping station is provided with a battery swapping channel 9, which extends along a first direction X. One end of the battery swapping channel 9 extends to the lower side of the battery swapping platform 1, and the other end extends to the lower side of the storage device 2. The battery swapping device 3 is disposed in the battery swapping channel 9 and is capable of moving within the battery swapping channel 9.

[0071] In some embodiments, the battery swapping device 3 includes an Automated Guided Vehicle (AGV).

[0072] In some embodiments, the battery swapping station includes a battery swapping platform 1, a storage device 2, a battery swapping device 3, a transfer device 4, and a cleaning device 5. The battery swapping platform 1 is used to carry a vehicle 7. The storage device 2 includes a plurality of storage compartments 21, each compartment 21 for storing and charging a battery device 8. The battery swapping device 3 is used to remove the battery device 8 from the vehicle 7 and to install the battery device 8 stored in the storage compartments 21 onto the vehicle 7. The transfer device 4 is used to transfer the battery device 8 between the storage device 2 and the battery swapping device 3. The cleaning device 5 is disposed on the transfer device 4 and is used to clean foreign matter from the surface of the battery device 8.

[0073] The cleaning device 5 can be fixedly installed on the transfer device 4 or it can be movably installed on the transfer device 4.

[0074] The cleaning device 5 can clean the battery device 8 in various ways. For example, the cleaning device 5 can remove foreign matter from the surface of the battery device 8 by blowing air, wiping, brushing, or other methods.

[0075] There can be one or more cleaning devices 5.

[0076] In this embodiment, the cleaning device 5 can clean foreign objects from the surface of the battery device 8, thereby reducing the risk of corrosion of the battery device 8, minimizing interference between foreign objects and other components during the disassembly and assembly of the battery device 8, and reducing the risk of battery swapping failure. The cleaning device 5 can also clean the battery device 8 during the transfer process by the transfer device 4, thus saving cleaning time, optimizing the battery swapping cycle, and improving battery swapping efficiency.

[0077] A cleaning device 5 is provided on the transfer device 4, which can clean all the battery devices 8 removed from the vehicle 7, thus simplifying the structure of the battery swapping station and reducing its cost. For example, compared to a scheme that provides a cleaning device 5 in each storage location 21, the embodiments of this application can reduce the number of cleaning devices 5, thereby reducing the cost of the battery swapping station.

[0078] In some embodiments, the transfer device 4 includes a frame 41 and a support mechanism 42 movably disposed on the frame 41. The support mechanism 42 is used to support the battery device 8, and the cleaning device 5 is located above the support mechanism 42. The support mechanism 42 is configured to move the battery device 8 along a first direction X, so that the cleaning device 5 cleans the battery device 8 during the movement of the battery device 8. The first direction X is perpendicular to the vertical direction Z.

[0079] The cleaning device 5 can be installed on the frame 41 or on the support mechanism 42.

[0080] As an example, "the cleaning device 5 is located above the support mechanism 42" can mean that the cleaning device 5 is higher than the support mechanism 42 in the vertical direction Z. In the vertical direction Z, the projection of the cleaning device 5 may or may not overlap with the support mechanism 42.

[0081] As an example, during the movement of the battery device 8 along the first direction X, the cleaning device 5 can move relative to the frame 41 in the first direction X, or it can be fixed relative to the frame 41 in the first direction X.

[0082] During the use of the battery device 8, foreign matter easily accumulates on its upper surface. Placing the cleaning device 5 on top of the support mechanism 42 helps clean this foreign matter. The support mechanism 42 can move the battery device 8 along the first direction X to pick up and place it. The cleaning device 5 and the battery device 8 can move relative to each other in the first direction X to clean the battery device 8. The cleaning device 5 can clean the battery device 8 during the pick-up and drop process by the support mechanism 42, thus saving cleaning time and improving battery swapping efficiency. The support mechanism 42 can provide power for the relative movement between the battery device 8 and the cleaning device 5; therefore, there is no need to set up a separate power mechanism for the cleaning device 5, thus simplifying the structure of the transfer device 4 and the cleaning device 5.

[0083] In some embodiments, the support mechanism 42 is configured to move relative to the frame 41 between a first position P1 and a second position P2, the first position P1 and the second position P2 being spaced apart along a first direction X. The cleaning device 5 is located between the first position P1 and the second position P2 in the first direction X to clean the battery device 8 as it passes by.

[0084] It should be noted that "the cleaning device 5 is located between the first position P1 and the second position P2 in the first direction X" does not require that the height of the cleaning device 5 in the vertical direction Z be the same as the height of the first position P1 in the vertical direction Z, nor does it require that the height of the cleaning device 5 in the vertical direction Z be the same as the height of the second position P2 in the vertical direction Z; for example, in the vertical direction Z, the cleaning device 5 may be higher than the first position P1 and the second position P2.

[0085] For example, in the first direction X, the cleaning device 5 may be entirely located between the first position P1 and the second position P2, or only a portion of it may be located between the first position P1 and the second position P2. For instance, in the first direction X, the lower end of the cleaning device 5 may be located between the first position P1 and the second position P2.

[0086] For example, the support mechanism 42 can move in other directions (vertical direction Z), and when the support mechanism 42 moves in other directions, the relative positions of the first position P1 and the second position P2 remain unchanged.

[0087] When the supporting mechanism 42 moves between the first position P1 and the second position P2, the battery device 8 can pass through the cleaning device 5 as a whole, which helps to increase the cleaning area of ​​the cleaning device 5 and improve the cleaning effect.

[0088] In some embodiments, when the support mechanism 42 is in the first position P1, the battery device 8 is in the first battery position; when the support mechanism 42 is in the second position P2, the battery device 8 is in the second battery position.

[0089] In the first direction X, the cleaning device 5 is positioned between the first battery position and the second battery position. The battery device 8 in the first battery position and the battery device 8 in the second battery position are spaced a certain distance apart in the first direction X.

[0090] In some embodiments, during the transfer of the battery device 8, the carrying mechanism 42 moves from the second position P2 to the first position P1, and the battery device 8 moves under the drive of the carrying mechanism 42 and passes through the cleaning device 5, where the cleaning device 5 cleans the upper surface of the battery device 8. During the transfer of the battery device 8, the carrying mechanism 42 moves from the first position P1 to the second position P2, and the battery device 8 moves under the drive of the carrying mechanism 42 and passes through the cleaning device 5, where the cleaning device 5 cleans the upper surface of the battery device 8 again. This embodiment of the application can perform two cleanings on the battery device 8, thereby improving the cleaning effect, reducing the risk of battery swapping failure, and improving battery swapping efficiency.

[0091] In some embodiments, the first position P1 is located inside the rack 41, and the second position P2 is located outside the rack 41.

[0092] When the carrying mechanism 42 is in the second position P2, the carrying mechanism 42 can extend to the outside of the frame 41 to facilitate gripping or placing the battery device 8; when the carrying mechanism 42 is in the first position P1, the carrying mechanism 42 can move the battery device 8 into the frame 41, thereby reducing the risk of interference between the battery device 8 and the carrying mechanism 42 and other components during the movement of the transfer device 4.

[0093] In some embodiments, the frame 41 has an opening on at least one side along the first direction X, and the support mechanism 42 can be moved outside the frame 41 through the opening, or moved inside the frame 41 through the opening.

[0094] In some embodiments, the frame 41 includes a plurality of beam structures 411, which are arranged circumferentially on the outside of the support mechanism 42 when the support mechanism 42 is in the first position P1.

[0095] In some embodiments, the transfer device 4 further includes a drive device 43. The drive device 43 can provide power for the movement of the support mechanism 42. Optionally, the drive device 43 is disposed on the frame 41.

[0096] In some embodiments, the drive device 43 includes a first drive member 431, which is used to drive the support mechanism 42 to move along a first direction X.

[0097] The first driving component 431 can be directly connected to the bearing mechanism 42, or it can be indirectly connected to the bearing mechanism 42 through other mechanisms.

[0098] In some embodiments, the first drive member 431 may include a telescopic fork. Exemplarily, the first drive member 431 includes a power member, a transmission member, and the fork, with the power member realizing the telescopic movement of the fork via the transmission member. For example, the power member may be a motor or a hydraulic system, and the transmission member may include a chain, rack and pinion, or other structures. A carrying mechanism 42 is disposed on the fork, and the telescopic movement of the fork enables the carrying mechanism 42 to move along a first direction X. In other embodiments, the carrying mechanism 42 may be integrated with the first drive member 431; for example, the carrying mechanism 42 may be part of the fork.

[0099] In some embodiments, the drive device 43 includes a second drive member 432, which is used to drive the support mechanism 42 to move up and down in the vertical direction Z.

[0100] The first driving member 431 can be directly connected to the bearing mechanism 42, or it can be indirectly connected to the bearing mechanism 42 through other mechanisms. For example, the second driving member 432 is connected to the first driving member 431, and drives the bearing mechanism 42 to move in the vertical direction Z through the first driving member 431.

[0101] The second drive unit 432 may include a motor, cylinder, hydraulic cylinder, or other structure capable of providing power.

[0102] The second drive member 432 provides power for the lifting and lowering of the support mechanism 42, so that the support mechanism 42 can support or place the battery device 8.

[0103] In some embodiments, the cleaning device 5 is configured to be vertically movable in the vertical direction Z.

[0104] In some embodiments, the support mechanism 42 and the cleaning device 5 are configured to move synchronously in the vertical direction Z.

[0105] For example, the support mechanism 42 and the cleaning device 5 can be raised and lowered by the same drive member or by different drive members.

[0106] When the support mechanism 42 is raised and lowered, the cleaning device 5 can be raised and lowered synchronously with the support mechanism 42, so that the cleaning device can clean the battery device 8 placed on the support mechanism 42.

[0107] In some embodiments, the transfer device 4 includes a transmission mechanism (not shown) that connects the cleaning device 5 and the carrying mechanism 42.

[0108] In some embodiments, the transmission mechanism connects the first drive member 431 and the cleaning device 5, and the second drive member 432 drives the bearing mechanism 42 to rise and fall through the first drive member 431 and drives the cleaning device 5 to rise and fall through the first drive member 431 and the transmission mechanism.

[0109] In some embodiments, the transmission mechanism includes a guide rail, a slider, and a connector. The guide rail can be fixed to the frame 41 and extends in the vertical direction Z. The first drive member 431 and the slider are slidably disposed on the guide rail, and the connector connects the slider and the first drive member 431.

[0110] In some embodiments, the drive device 43 can also drive the frame 41 to move along the second direction Y, where the second direction Y, the first direction X, and the vertical direction Z are perpendicular to each other. The drive device 43 can also drive the support mechanism 42 to move along the second direction Y via the frame 41.

[0111] The support mechanism 42 can move in the second direction Y, the first direction X and the vertical direction Z, which makes it easy for the support mechanism 42 to pick up and put in the battery device 8 in each storage position 21.

[0112] In some embodiments, at least a portion of the plurality of storage bits 21 are arrayed along the second direction Y and the vertical direction Z.

[0113] In some embodiments, the battery swapping station further includes a buffer device 6, which includes a plurality of buffer bits 61, each buffer bit 61 for storing a battery device 8. The plurality of buffer bits 61 of the buffer device 6 are used for transferring the battery device 8 between the transfer device 4 and the battery swapping device 3, and for transferring the battery device 8 between the transfer device 4 and the storage device 2.

[0114] For example, the battery swapping device 3 can place the depleted battery device 8 removed from the vehicle 7 into a buffer position 61, and then the battery swapping device 3 can remove the fully charged battery device 8 stored in another buffer position 61 and install the fully charged battery device 8 into the vehicle 7; the transfer device 4 can remove the depleted battery device 8 and transfer it to a storage position 21 for charging, and then the transfer device 4 can remove the fully charged battery device 8 stored in another storage position 21 and place the fully charged battery device 8 into a buffer position 61; the fully charged battery device 8 can be used for the next battery swap of the vehicle 7.

[0115] By setting multiple buffer bits 61 in this embodiment, the time for the transfer device 4 to transfer the battery device 8 and the time for the battery swapping device 3 to install and remove the battery device 8 can partially overlap, which is beneficial to optimize the battery swapping cycle and improve the battery swapping efficiency.

[0116] In some embodiments, a plurality of cache bits 61 are set along the second direction Y.

[0117] In some embodiments, the battery swapping device 3 can be moved to the underside of a buffer position 61.

[0118] In some embodiments, multiple buffer positions 61 can be moved along the second direction Y. For example, after the battery swapping device 3 removes the depleted battery device 8 from the vehicle 7, it moves to the bottom of an empty buffer position 61. Then, the battery swapping device 3 places the depleted battery device 8 into the empty buffer position 61. The multiple buffer positions 61 move together along the second direction Y a certain distance, so that the buffer position 61 containing the fully charged battery device 8 moves to the top of the battery swapping device 3, and the buffer position 61 containing the depleted battery device 8 moves to one side. Then, the battery swapping device 3 removes the fully charged battery device 8.

[0119] In some embodiments, the cache device 6 and the storage device 2 are integrated together to form a battery holder.

[0120] In some embodiments, the cleaning device 5 includes a cleaning member 51, at least a portion of which is disposed on the movement path. Optionally, as the battery device 8 passes under the cleaning member 51, the cleaning member 51 contacts the upper surface of the battery device 8.

[0121] During the movement of the battery device 8, the cleaning component 51 can block foreign objects on the battery device 8; as the battery device 8 moves, the foreign objects fall off the battery device 8 under the action of the cleaning component 51.

[0122] In some embodiments, the cleaning device 5 includes a collection box 52, the upper side of which has an opening 521, the opening 521 being no higher than the lower end of the cleaning member 51. In the second direction Y, the projection of the cleaning member 51 along the vertical direction Z is located inside the projection of the collection box 52 along the vertical direction Z, and the second direction Y, the first direction X, and the vertical direction Z are perpendicular to each other.

[0123] As an example, when the battery device 8 passes the cleaning member 51, the collection box 52 may be located on one side of the battery device 8 along the second direction Y.

[0124] It should be noted that "in the second direction Y, the projection of the cleaning component 51 along the vertical direction Z is located inside the projection of the collection box 52 along the vertical direction Z" can mean "in the second direction Y, the projection of the cleaning component 51 along the vertical direction Z is located on the side of the projection of the collection box 52 along the vertical direction Z that is closer to the projection of the battery device 8 along the vertical direction Z".

[0125] During the movement of the battery device 8, the cleaning component 51 can block foreign objects on the battery device 8; as the battery device 8 moves, the foreign objects fall off under the action of the cleaning component 51 and fall into the collection box 52 through the opening 521. The collection box 52 can collect foreign objects to reduce the impact of foreign objects on the internal environment of the battery swapping station and reduce the interference caused by foreign objects to the battery swapping station.

[0126] In some embodiments, in the vertical direction Z, the opening 521 of the collection box 52 is lower than the lower end of the cleaning member 51.

[0127] In some embodiments, in the first direction X, both ends of the opening 521 of the collection box 52 extend beyond the cleaning member 51. The collection box 52 has a large opening 521 to better collect foreign objects and reduce the contamination of the internal environment of the battery swapping station by foreign objects.

[0128] In some embodiments, the opening 521 of the collection box 52 is below the surface of the battery device 8 that needs to be cleaned.

[0129] In some embodiments, the frame 41 is provided with two cleaning devices 5 on the same side along the first direction X, and the two cleaning devices 5 are spaced apart along the second direction Y, wherein the second direction Y, the first direction X and the vertical direction Z are perpendicular to each other.

[0130] The two cleaning devices 5 can clean both ends of the battery device 8 along the second direction Y, which helps to increase the cleaning area of ​​the cleaning devices 5 and improve the cleaning effect.

[0131] In some embodiments, in the second direction Y, the distance between the collection boxes 52 of the two cleaning devices 5 is greater than the distance between the cleaning components 51 of the two cleaning devices 5.

[0132] In the second direction Y, there is a large distance between the collection boxes 52 of the two cleaning devices 5 so that the battery device 8 can pass between the collection boxes 52 of the two cleaning devices 5. In the second direction Y, there is a small distance between the cleaning parts 51 of the two cleaning devices 5 so that the two cleaning parts 51 can overlap with the battery device 8 in the vertical direction Z, thereby cleaning the upper surface of the battery device 8.

[0133] In some embodiments, the cleaning device 5 may clean the entire upper surface of the battery device 8 or only a portion of the upper surface of the battery device 8.

[0134] In some embodiments, the vehicle 7 has a battery support structure, and the battery device 8 is detachably mounted on the battery support structure.

[0135] In some embodiments, the battery device 8 includes a housing 81 and a locking mechanism 82 disposed on the housing 81, at least a portion of the locking mechanism 82 protruding from the upper surface of the housing 81 and used for locking to the battery support structure.

[0136] The cleaning device 5 can be used to clean at least a portion of the upper surface of the housing 81.

[0137] In some embodiments, the upper surface of the housing 81 needs to be in contact with the battery support structure. If foreign matter accumulates on the upper surface of the housing 81, it may affect the fit between the housing 81 and the battery support structure, potentially causing the locking mechanism 82 to fail to connect with the battery support structure. The cleaning device 5 can clean the upper surface of the housing 81 to reduce the risk of failure in the connection between the locking mechanism 82 and the battery support structure.

[0138] Optionally, the cleaning device 5 can be primarily used to clean the upper surface of the housing 81 in areas that need to be in contact with the battery-supporting structure.

[0139] In some embodiments, the upper surface of the housing 81 is provided with two edge regions 811 at both ends along the second direction Y, and each edge region 811 is provided with a locking mechanism 82.

[0140] The two cleaning devices 5 can be used to clean the two edge areas 811 respectively.

[0141] In some embodiments, the edge region 811 is used to fit with the battery support structure.

[0142] In some embodiments, the upper surface of the housing 81 includes a protruding region located between two edge regions 811 in the second direction Y.

[0143] In some embodiments, the battery device 8 further includes a positioning member 83 disposed on the housing 81, at least a portion of the positioning member 83 protruding from the edge region 811. Optionally, there are two positioning members 83, with the two positioning members 83 respectively disposed on two edge regions 811.

[0144] In some embodiments, the edge region 811 extends along the length direction of the battery device 8. Optionally, the edge region 811 extends from one end of the battery device 8 along the length direction to the other end of the battery device 8 along the length direction.

[0145] In some embodiments, when the support mechanism 42 moves the battery device 8 along the first direction X, the first direction X is parallel to the length direction of the battery device 8.

[0146] In some embodiments, when the support mechanism 42 moves from the first position P1 to the second position P2, the distance that the battery device 8 moves in the first direction X is greater than the length of the battery device 8.

[0147] When the support mechanism 42 moves between the first position P1 and the second position P2, the cleaning component 51 can clean the entire edge area 811 in the first direction X.

[0148] In some embodiments, the cleaning device 5 includes a cleaning element 51 and a rotating shaft 53. The rotating shaft 53 is connected to the frame 41, and the cleaning element 51 is rotatably connected to the rotating shaft 53. The axis of the rotating shaft 53 is parallel to the second direction Y, and the second direction Y, the first direction X, and the vertical direction Z are perpendicular to each other. At least a portion of the cleaning element 51 is located below the rotating shaft 53 and is disposed on the movement path of the battery device 8.

[0149] The rotating shaft 53 can be fixedly connected to the frame 41 or movably connected to the frame 41. For example, the rotating shaft 53 is movably connected to the frame 41 in the vertical direction Z.

[0150] During the movement of the battery device 8, the cleaning member 51 can block foreign objects on the battery device 8. When a small foreign object is blocked by the cleaning member 51, it will fall off under the action of the cleaning member 51 as the battery device 8 moves. When there is a large foreign object T on the battery device 8, the large foreign object T may be stuck by a protruding structure on the battery device 8 (such as a positioning member 83 or a locking mechanism 82). In this case, the cleaning member 51 can rotate around the pivot 53 and pass over the large foreign object T, thereby posing a risk of damage to the cleaning member 51 and the battery device 8. After passing over the large foreign object T, the cleaning member 51 can drop back into position under the action of gravity and continue cleaning foreign objects in the area behind it.

[0151] In some embodiments, during the transfer of the battery device 8, the carrying mechanism 42 moves back and forth between a second position P2 and a first position P1. If a large foreign object T becomes stuck and is not removed during the movement of the carrying mechanism 42 from the second position P2 to the first position P1, then during the movement of the carrying mechanism 42 from the first position P1 to the second position P2, the cleaning member 51 blocks the large foreign object T from the opposite direction, thereby removing the large foreign object T.

[0152] In some embodiments, the cleaning component 51 includes a connecting rod 511 and a flexible component 512, the upper end of the connecting rod 511 being rotatably connected to the rotating shaft 53, and the flexible component 512 being connected to the lower end of the connecting rod 511.

[0153] As an example, the flexible component 512 may be a brush, foam, sponge or other flexible structure.

[0154] Using the flexible component 512 to clean the battery device 8 reduces the risk of wear and tear during the cleaning process. The connecting rod 511 has a certain weight and rigidity, preventing deformation or bending when foreign objects are blocked by the flexible component 512. The connecting rod 511 restricts the movement of the flexible component 512, allowing it to wipe the battery device 8 and remove foreign objects from its surface. When a larger foreign object T is caught by a protruding structure on the battery device 8, the connecting rod 511 can rotate around the pivot 53, allowing the flexible component 512 to pass over the larger object T.

[0155] In some embodiments, the link 511 is made of a rigid material. Exemplarily, the link 511 may be made of metal, rigid plastic, or wood.

[0156] In some embodiments, the cleaning device 5 further includes a detector 54 for detecting the angle of rotation of the cleaning component 51.

[0157] The detector 54 can detect the angle of rotation of the cleaning component 51 around the shaft 53, thereby determining whether there are large foreign objects T remaining on the surface of the battery device 8. If it is determined that there are large foreign objects T remaining on the surface of the battery device 8, the battery swapping station can use other methods to remove the foreign objects.

[0158] For example, when the cleaning component 51 rotates at an angle exceeding a set angle (e.g., 25°, 30°, 35°, 40° or 45°), a large amount of foreign matter T remains on the surface of the battery device 8.

[0159] For example, when it is determined that a large foreign object T remains on the surface of the battery device 8, the battery swapping station can send an alarm to the station's maintenance personnel, who can then manually clean it.

[0160] For example, in its natural state, the connecting rod 511 can be parallel to the vertical direction Z. During the cleaning of the battery device 8, the cleaning member 51 can rotate about the axis 53 by an angle that is the angle between the connecting rod 511 and the vertical direction Z.

[0161] In some embodiments, during the transfer of the battery device 8, the support mechanism 42 moves back and forth between the second position P2 and the first position P1. If the cleaning component 51 exhibits significant rotation during both cleaning cycles, the detector 54 identifies a large foreign object T that was not removed during the two cleaning cycles.

[0162] In some embodiments, detector 54 includes an encoder.

[0163] In some embodiments, after the cleaning member 51 hangs down naturally, its lower end (e.g., flexible member 512) can contact the surface of the battery device 8 that needs to be cleaned.

[0164] In some embodiments, in the second direction Y, the lower end of the cleaning member 51 is located within the boundary of the area to be cleaned of the battery device 8.

[0165] In some embodiments, the cleaning device 5 includes an elastic element (not shown) connected to the cleaning member 51, the elastic element being used to apply elastic resistance to the cleaning member 51 when the cleaning member 51 rotates.

[0166] When a small foreign object is blocked by the cleaning member 51, the elastic force of the elastic member can limit the rotation range of the cleaning member 51, so that the small foreign object falls under the action of the cleaning member 51. When there is a larger foreign object T in the battery device 8, the larger foreign object T may be stuck by the protruding structure on the battery device 8 (such as the positioning member 83 or the locking mechanism 82). At this time, the cleaning member 51 overcomes the resistance of the elastic member and can rotate a large range around the pivot 53, thereby passing over the larger foreign object T. After passing over the larger foreign object T, the cleaning member 51 can be reset under the action of the elastic force and continue to clean the foreign objects in the subsequent area.

[0167] In some embodiments, the elastic element may include a torsion spring.

[0168] Figure 8 is a schematic diagram of a partial structure of a battery swapping station provided in some other embodiments of this application.

[0169] Referring to Figure 8, in some embodiments, the support mechanism 42 is configured to be movable to both sides of the frame 41 along the first direction X.

[0170] As an example, there are two second positions P2, which are located on either side of the first position P1.

[0171] The embodiments of this application can increase the movement range of the support mechanism 42, which helps the support mechanism 42 to pick up and put down the battery device 8.

[0172] In some embodiments, cleaning devices 5 are provided on both sides of the frame 41 along the first direction X. The cleaning devices 5 located on both sides of the frame 41 can clean the battery device 8, which helps to increase the cleaning area and improve the cleaning effect.

[0173] In some embodiments, there are two storage devices 2, which are respectively disposed on both sides of the rack 41 along the first direction X. The transfer device 4 can place the battery device 8 in one storage device 2 or in the other storage device 2.

[0174] Cleaning devices 5 are provided on both sides of the rack 41. No matter which storage device 2 the transfer device 4 places the battery device 8 in, the cleaning device 5 can clean the battery device 8.

[0175] In some embodiments, there are four cleaning devices 5. Two cleaning devices 5 are located on one side of the frame 41 along the first direction X and are spaced apart along the second direction Y. The other two cleaning devices 5 are located on the other side of the frame 41 along the first direction X and are spaced apart along the second direction Y.

[0176] Figure 9 is a schematic diagram of a partial structure of a battery swapping station provided in some embodiments of this application.

[0177] Referring to FIG9, in some embodiments, the transfer device 4 includes a drive device 43 disposed on the frame 41. The drive device 43 includes a third drive member 433, which is connected to the cleaning device 5 and is used to drive the cleaning device 5 to lift and lower.

[0178] The third drive unit 433 may include a cylinder, a motor, a hydraulic cylinder, or other drive units.

[0179] By providing a third drive component 433, the lifting and lowering of the cleaning device 5 can be independently controlled, thereby adapting to battery devices 8 at different heights. Furthermore, the third drive component 433 can also change the distance between the cleaning device 5 and the support mechanism 42, thereby adjusting the friction between the cleaning device 5 and the battery device 8 and improving the cleaning effect.

[0180] For example, when the cleaning component 51 encounters a large foreign object T that is stuck, the third driving component 433 can also drive the cleaning component 51 to rise so that the cleaning component 51 can pass over the foreign object; after passing over the large foreign object T, the third driving component 433 can drive the cleaning component 51 to fall so as to continue cleaning other areas.

[0181] Figure 10 is a schematic flowchart of a battery swapping method provided in some embodiments of this application.

[0182] Referring to Figures 1 to 7 and Figure 10, an embodiment of this application provides a battery swapping method, which includes:

[0183] S100, drive vehicle 7 to battery swapping platform 1;

[0184] S200, battery swapping device 3 removes battery device 8 from vehicle 7;

[0185] S300, the transfer device 4 receives the battery device 8 removed from the vehicle 7 by the battery swapping device 3;

[0186] S400, cleaning device 5 cleans foreign objects from the surface of battery device 8;

[0187] S500, the transfer device 4 places the battery device 8 into a storage position 21 of the storage device 2.

[0188] In step S300, the transfer device 4 can directly receive the battery device 8 from the battery swapping device 3. Alternatively, the battery swapping device 3 can transfer the battery device 8 to the buffer device 6, and the transfer device 4 can receive the battery device 8 from the buffer device 6.

[0189] In this embodiment, the cleaning device 5 can clean foreign objects from the surface of the battery device 8, thereby reducing the risk of corrosion of the battery device 8, minimizing interference between foreign objects and other components during the disassembly and assembly of the battery device 8, and reducing the risk of battery swapping failure. The cleaning device 5 can also clean the battery device 8 during the transfer process by the transfer device 4, thus saving cleaning time, optimizing the battery swapping cycle, and improving battery swapping efficiency.

[0190] In some embodiments, step S300 includes: the carrying mechanism 42 of the transfer device 4 moving from a first position P1 to a second position P2 along a first direction X, and supporting the battery device 8 removed from the vehicle 7 by the battery swapping device 3.

[0191] In some embodiments, step S300 includes:

[0192] S310, the battery swapping device 3 transfers the battery device 8 removed from the vehicle 7 to an empty buffer slot 61 of the buffer device 6;

[0193] S320, the carrying mechanism 42 of the transfer device 4 moves from the first position P1 to the second position P2 along the first direction X, so that the carrying mechanism 42 moves to the lower side of the battery device 8, and the carrying mechanism 42 lifts and supports the battery device 8.

[0194] For example, in step S320, the first position P1 and the second position P2 move upward synchronously.

[0195] In some embodiments, step S400 includes:

[0196] S410, the carrying mechanism 42 moves from the second position P2 toward the first position P1, the battery device 8 passes through the cleaning device 5, and the cleaning device 5 cleans at least a portion of the upper surface of the battery device 8.

[0197] S420. After the carrying mechanism 42 moves to the first position P1, the transfer device 4 moves toward the storage device 2 to the preset position.

[0198] S430, the carrying mechanism 42 moves from the first position P1 toward the second position P2, and the battery device 8 passes through the cleaning device 5, which cleans at least a portion of the upper surface of the battery device 8.

[0199] For example, in step S420, the transfer device 4 moves the battery device 8 to a position corresponding to an empty storage slot 21.

[0200] In this embodiment of the application, the battery device 8 is cleaned twice during the transfer process, thereby improving the cleaning effect and reducing the risk of corrosion of the battery device 8.

[0201] In some embodiments, step S500 includes:

[0202] Step S510: After the support mechanism 42 moves to the second position P2, the support mechanism 42 descends to place the battery device 8 into a storage position 21 of the storage device 2, and the storage position 21 charges the battery device 8.

[0203] In some embodiments, step S500 further includes S520: the carrying mechanism 42 of the transfer device 4 moves from the second position P2 to the first position P1.

[0204] In some embodiments, the battery swapping method further includes step S600: the transfer device 4 transfers the fully charged battery device 8 stored in the storage location 21 to the buffer device 6.

[0205] In some embodiments, step S600 includes:

[0206] S610, the transfer device 4 operates to move the carrying mechanism 42 to a position corresponding to a storage position 21, which holds a fully charged battery device 8.

[0207] S620, the carrying mechanism 42 of the transfer device 4 moves from the first position P1 to the second position P2, so that the carrying mechanism 42 moves to the lower side of the fully charged battery device 8, and the carrying mechanism 42 lifts and supports the fully charged battery device 8.

[0208] S630, the carrying mechanism 42 moves from the second position P2 to the first position P1, and the fully charged battery device 8 moves under the drive of the carrying mechanism 42. When the fully charged battery device 8 passes through the cleaning device 5, the cleaning device 5 cleans at least a portion of the upper surface of the fully charged battery device 8.

[0209] S640. After the carrying mechanism 42 moves to the first position P1, the transfer device 4 drives the fully charged battery device 8 to move to the position corresponding to an empty buffer position 61 of the buffer device 6.

[0210] S650, the carrying mechanism 42 moves from the first position P1 to the second position P2, and the fully charged battery device 8 moves under the drive of the carrying mechanism 42. When the fully charged battery device 8 passes the cleaning device 5, the cleaning device 5 cleans at least a portion of the upper surface of the fully charged battery device 8 again.
