Description

Technical Field

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

[0002] The installation of batteries in existing electric vehicles is generally divided into fixed and swappable types. For swappable batteries, a movable installation method is generally used, which allows the battery to be removed at any time for replacement or charging, and then installed back onto the vehicle body after replacement or charging is completed.

[0003] Currently, for trucks, especially light trucks, batteries are typically located on both sides of the vehicle. Therefore, battery swapping in light trucks requires two separate swapping units on each side of the vehicle. This places high demands on the swapping station's space, requiring a large area. Furthermore, the need for two sets of swapping equipment significantly increases costs and reduces efficiency. Additionally, placing the batteries on both sides of the vehicle requires brackets for mounting, complicating the vehicle structure and hindering swapping. Therefore, a swapping device that can swap batteries from the bottom of a light truck could be considered. This would allow a single swapping unit to complete the entire swap. In this scenario, the battery, located under the vehicle, can be directly attached to the chassis frame, simplifying the vehicle structure and facilitating swapping. However, considering the relatively large size and weight of light truck batteries, the overall structure of the swapping device would also be correspondingly large. Additionally, the limited space due to the battery's location under the vehicle necessitates the design of a swapping device specifically tailored to the needs of light trucks to achieve bottom-mounted battery swapping. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology of complex dual-side battery swapping operation, high battery swapping cost and low efficiency, and to provide a modular battery swapping device.

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

[0006] A modular battery swapping device for chassis-based battery swapping of battery swapping vehicles, comprising:

[0007] The frame module includes two lifting modules and two moving modules arranged opposite each other, and the area between the lifting modules and the moving modules forms a central receiving area. The moving modules can drive the frame module to move along a first direction.

[0008] A battery swapping platform is located in the central accommodating area. The battery swapping platform is connected to two lifting modules respectively, so that the battery swapping platform can be lifted to move up and down relative to the frame module.

[0009] This solution employs a modular design, with the frame module comprising a moving module and a lifting module. By positioning the moving module, lifting module, and battery swapping platform in different locations, each module can be assembled independently, improving the overall production efficiency of the battery swapping device. The battery swapping platform, located in the central storage area with two opposing lifting modules and two opposing moving modules, results in a more compact structure. The modules and frame do not overlap in the vertical direction, reducing the overall height of the battery swapping device. Furthermore, it enables bottom-mounted battery swapping for light trucks, allowing for the complete battery removal and installation using a single swapping device, significantly reducing the cost and increasing the efficiency of battery swapping for light trucks.

[0010] Preferably, the battery swapping platform includes a platform base plate, a battery swapping module and multiple support modules disposed on the platform base plate, the platform base plate being connected to the lifting module so that the platform base plate can be lifted by the lifting module, the battery swapping module being used to install the battery onto the vehicle or remove the battery from the vehicle, and the support modules being disposed on both sides of the battery swapping module so that the support modules and the battery swapping module can jointly support the battery.

[0011] In this solution, the platform base plate is connected to the lifting module, which can drive the battery replacement module to rise and fall to cooperate with the vehicle chassis for battery swapping. The platform base plate provides a mounting frame for the battery replacement module. The battery replacement module and the support module together provide a load-bearing surface for the battery, making the contact surface of the battery wider during the replacement process, thus meeting the needs of replacing large-size batteries, and making the battery replacement process more stable.

[0012] Preferably, the plurality of support modules are respectively disposed on both sides of the battery replacement module along the first direction, and the support modules and the battery replacement module are spaced apart by a predetermined distance to form a double-extending receiving area, so that the double extension of the battery transfer mechanism can lift the battery from under the battery for transfer.

[0013] In this solution, the battery swapping platform is equipped with a double-extended receiving area. By arranging this area on both sides of the battery replacement module, it facilitates the double-extended battery transfer mechanism to pick up and place batteries relative to the battery replacement module, and provides reasonable operating space.

[0014] Preferably, the battery replacement module includes a base and an unlocking mechanism and a tray disposed on the base. The base is connected to the platform base plate and can move relative to the platform base plate in a second direction perpendicular to the first direction. The unlocking mechanism is located below the tray, and the tray has a through hole so that the unlocking mechanism can pass through the through hole to unlock the battery during operation.

[0015] In this design, the tray provides a support surface for the battery. The tray has through holes, which provide unlocking space for the unlocking mechanism when it is locking or unlocking the battery. At the same time, when the unlocking mechanism is not in operation, it returns to the bottom of the tray, thus protecting the unlocking mechanism from damage.

[0016] Preferably, there are two unlocking mechanisms, which are fixed to the base on both sides along the second direction.

[0017] In this solution, two unlocking structures are set up, corresponding to two unlocking points in the battery, which results in high unlocking efficiency and a high success rate.

[0018] Preferably, the base is further provided with a vehicle positioning post for positioning with the vehicle, the vehicle positioning post being located on the first side of the battery replacement module, and the tray is provided with a battery positioning post for positioning with the battery, the battery positioning post being located at least on the second side of the battery replacement module, the first side and the second side being the two sides of the battery replacement module along the first direction, respectively.

[0019] In this solution, the vehicle positioning post is used to determine the position between the battery swapping device and the battery swapping vehicle, while the battery positioning post is used by the battery swapping device to locate the battery of the battery swapping vehicle. The dual positioning method makes the positioning more accurate, which in turn helps to improve the unlocking success rate.

[0020] Preferably, the tray is buoyantly connected to the base, and the support module is buoyantly connected to the platform base plate. When the battery swapping platform is not carrying a battery, the bearing surface of the tray and the bearing surface of the support module are at the same height.

[0021] In this design, the tray is buoyantly connected to the base, and the support module is buoyantly connected to the platform base. When carrying a battery, the tray and support module can act as a buffer, while increasing the contact area between the battery and the tray and support module, resulting in higher stability. Furthermore, when not carrying a battery, both are at the same height, and when carrying a battery, the system is more stable.

[0022] Preferably, each side of the battery replacement module is provided with at least two support modules, and the support modules are spaced apart along the second direction.

[0023] In this solution, multiple support modules can distribute the force when supporting the battery, increase the contact points with the battery, and thus improve the battery's load-bearing stability, which is beneficial for replacing larger batteries.

[0024] Preferably, the lifting module includes a lifting frame extending along a second direction perpendicular to the first direction and a lifting mechanism mounted on the lifting frame. The lifting mechanism includes a lifting motor and a lifting member disposed on the side wall of the lifting frame facing the battery swapping platform. The lifting member is connected to the battery swapping platform so that the lifting motor can drive the lifting member to move and drive the battery swapping platform to rise and fall.

[0025] In this solution, the lifting frame provides installation space for the lifting mechanism, which enables the battery swapping platform to be raised and lowered.

[0026] Preferably, the lifting frame has a hollow cavity, and the lifting motor is disposed within the cavity.

[0027] In this design, the lifting motor is housed within the cavity, which helps save space and results in a more compact structure.

[0028] Preferably, there are two lifting components, which are spaced apart on the side wall of the lifting frame along the second direction. The lifting mechanism also includes a transmission assembly connected to the lifting motor. The transmission assembly is located on the side of the lifting frame facing the battery swapping platform and is connected to both lifting components, so that the lifting motor can drive both lifting components simultaneously.

[0029] In this solution, through the transmission assembly, the motor inside the lifting frame can simultaneously drive two lifting components located on the same lifting frame. The two lifting components can move synchronously, eliminating the need for two separate motors, thus saving resources. By using two lifting components, the lifting force is more balanced, and the lifting process is more stable.

[0030] Preferably, the moving module includes a moving frame extending along the first direction and at least two walking components spaced apart along the first direction below the moving frame. Each lifting module has an end receiving area on the side opposite to the battery swapping platform. The end receiving area is provided with a walking drive motor to drive the walking components to move the frame module.

[0031] In this design, the drive motor is located in the end housing area, which maximizes space utilization and makes the overall structure more compact.

[0032] Preferably, the mobile frame is provided with a walking component at both the head and tail ends along the first direction, and the mobile frame is also provided with a walking drive motor at both the head and tail ends, with each walking drive motor driving two walking components located at the head or tail ends.

[0033] In this design, walking components are installed at both ends of the mobile frame. Structurally, the force points of the mobile frame are located at both ends when it moves, which makes it more stable and helps to increase the load-bearing capacity. In addition, the walking drive motors installed at both ends help to control the accuracy of the battery swapping equipment's movement.

[0034] Preferably, a synchronization component is provided between the two traveling components located at the head or tail end. The synchronization component is connected to the traveling drive motor through a gear set. The gear set includes a first gear connected to the traveling drive motor and a second gear connected to the synchronization component. The first gear and the second gear are arranged and meshed vertically from top to bottom.

[0035] In this solution, the walking drive motor provides power to the walking components through a synchronization assembly and gear set, achieving stable operation of the battery swapping device while saving space resources. The walking components can maintain synchronous operation, improving the reliability and stability of the mobile module during operation.

[0036] Preferably, one of the movable frames is further provided with a guide member below it, the guide member being located between the two walking members at the front and rear ends; the other movable frame is further provided with a support member below it, the support member being located between the two walking members at the front and rear ends and being correspondingly provided with the guide member.

[0037] In this solution, by setting a guide under one frame, the movement of the battery swapping device can be guided, ensuring that the battery swapping device moves along a preset trajectory. By setting a support under another moving frame, the overall load-bearing capacity of the battery swapping device can be provided, increasing the weight it can bear.

[0038] Preferably, the movable frame includes a first region, a second region, and a third region connected along one side of the first direction. The first region and the third region have a first height in the vertical direction that is higher than the second height of the second region in the vertical direction. The length of the second region extending along the first direction is not less than the distance between the outermost edges of the two support modules arranged along the first direction.

[0039] In this design, the second area is lower than the first and third areas, providing more space and ensuring a more ample installation space for the battery swapping platform. This helps to reduce the overall height of the battery swapping device, enabling it to meet the battery swapping needs of light trucks with limited space at the bottom.

[0040] Preferably, the battery swapping platform includes a platform base plate, a battery replacement module and multiple support modules disposed on the platform base plate, the battery replacement module includes a base and a tray disposed on the base, the bearing surface of the tray and the bearing surface of the support module are both lower than the first height and higher than the second height.

[0041] In this design, both the bearing surface of the tray and the bearing surface of the support module are lower than the first height and higher than the second height, which helps to reduce the overall height of the battery swapping device, while the second area of ​​the moving frame will not interfere with the battery.

[0042] Preferably, the battery swapping platform includes a battery replacement module, the battery replacement module includes a base, the base is provided with a vehicle positioning post for positioning with the vehicle, and the base on the side provided with the vehicle positioning post extends outward at least to above the movable frame in the second region.

[0043] In this solution, the base on the side where the vehicle positioning column is located extends outward at least to the top of the movable frame in the second region. The height of the second region is relatively low, and the base extends to this location to meet the needs of large-size battery installation and removal and to ensure that the overall structure of the battery swapping equipment is not too large, thus making the battery swapping equipment structure compact.

[0044] Preferably, a sliding assembly is provided between the mobile module and the battery swapping platform. The sliding assembly includes a guide rail and a slider that cooperate with each other. The mobile frame is provided with one of the guide rail and the slider in both the first region and the third region, and the battery swapping platform is provided with the other of the guide rail and the slider in the corresponding location.

[0045] In this solution, the stability of the battery swapping platform during ascent and descent is ensured by the cooperation of the guide rail and the slider. Furthermore, the limiting effect of the guide rail and the slider ensures that the battery swapping platform will not deviate in any other direction during ascent and descent.

[0046] Preferably, the movable frame is further provided with a first cable groove extending along the first direction. The first cable groove is provided with a first inlet and a first outlet. The first inlet is used to allow a first cable to enter the first cable groove, and the first outlet is provided at the first end and the last end of the movable frame to allow the first cable in the first cable groove to be led out to supply power to the device in the frame module.

[0047] In this design, the first cable tray is located inside the movable frame, providing ample space for cable routing. Running the cables from inside the movable frame not only avoids occupying external space and results in a compact structure, but also prevents the cables from colliding with external components, making it safer.

[0048] Preferably, the battery swapping platform is further provided with a second cable trough extending along the first direction. The second cable trough is provided with a second inlet and a second outlet. The second inlet is used to allow a second cable to enter the second cable trough, and the second outlet is located in the middle of the battery swapping platform to allow the second cable in the second cable trough to be led out to supply power to the equipment in the battery swapping platform.

[0049] In this design, the second cable tray provides space for the second cable, which is more regularly laid out and will not interfere with other moving parts, making the power supply of the battery swapping device more stable.

[0050] Preferably, the second cable tray is adjacent to the first cable tray, and the second inlet is correspondingly provided to the first outlet, so that the second cable is laid in the first cable tray and enters the second cable tray from the first outlet and the second inlet.

[0051] In this scheme, the second cable tray is arranged adjacent to the first cable tray and the second cable inlet corresponds to the first cable outlet, so that the cable can pass through the first cable tray and then into the second cable tray, thus extending the cable arrangement space.

[0052] Preferably, an arched connector is provided between the second inlet and the first outlet, the arched connector being hollow to allow the second cable to pass through.

[0053] In this solution, the arched connector provides a transition for the second cable to pass through the first and second cable troughs, which can protect the second cable. Especially during the raising and lowering of the battery swapping platform, it facilitates the second cable to move or return to its original position and prevents the cables from getting tangled or being pulled or bent, which could lead to problems such as damage to the cable sheath or breakage of the wire core.

[0054] Preferably, each of the lifting modules has an end receiving area on the side opposite to the battery swapping platform. The frame module also includes a first junction box, which is disposed in the end receiving area and located above the synchronization component. The first junction box has a first inlet terminal and a plurality of first outlet terminals. The first inlet terminal is used to connect to a first low-voltage cable in the first cable, and the plurality of first outlet terminals are respectively used to connect to low-voltage equipment in the frame module.

[0055] And / or, the battery swapping platform further includes a second junction box, which is disposed between two support modules on one side of the battery swapping module. The second junction box has a second inlet terminal and multiple second outlet terminals. The second inlet terminal is used to connect to the second low-voltage cable in the second cable, and the multiple second outlet terminals are respectively used to connect to the low-voltage equipment in the battery swapping platform.

[0056] Using the first and second junction boxes as relays can reduce the number of incoming lines, facilitate the connection of low-voltage equipment and cables in different locations, reduce the overall wiring difficulty, improve wiring neatness, and also save on cable length and reduce costs.

[0057] A battery swapping station includes a modular battery swapping device as described above, which can travel within a pre-set battery swapping channel of the station and to a battery swapping point to swap batteries for vehicles.

[0058] In this solution, the aforementioned battery swapping device is used, and the battery swapping station can meet the battery swapping requirements of light trucks.

[0059] Preferably, the battery swapping channel is provided with limiting mechanisms at both ends, so that the battery swapping device can only move within the battery swapping channel.

[0060] In this solution, the limiting mechanism ensures that the battery swapping device will not deviate from the battery swapping channel, thereby protecting the battery swapping device from collision with nearby objects.

[0061] The positive and progressive effects of this invention are as follows: This invention adopts a modular design, with the frame module including a moving module and a lifting module. By positioning the moving module, lifting module, and battery swapping platform at different locations, each module can be assembled independently, which improves the overall production efficiency of the battery swapping device. With two opposing lifting modules and two opposing moving modules, the battery swapping platform is located in the central accommodating area, resulting in a more compact structure. The modules and frame do not overlap in the height direction, which helps reduce the overall height of the battery swapping device. Simultaneously, it enables bottom-mounted battery swapping for light trucks, allowing for the entire vehicle's battery to be installed and removed using a single swapping device, significantly reducing the cost of battery swapping for light trucks and improving swapping efficiency.

[0110] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0111] This embodiment provides a modular battery swapping device, such as... Figure 1 , Figure 2 and Figure 7 As shown, the chassis-based battery swapping system used for battery swapping vehicles includes:

[0112] The frame module includes two lifting modules 100 and two moving modules 300 arranged opposite to each other, and the area between the lifting modules 100 and the moving modules 300 forms a central receiving area 500. The moving modules 300 can drive the frame module to move along the first direction A.

[0113] The battery swapping platform is located in the central housing area 500. The battery swapping platform is connected to two lifting modules 100 respectively, so that the battery swapping platform can be lifted and moved up and down relative to the frame module.

[0114] Specifically, such as Figure 1As shown, along the first direction A, both ends of the battery swapping device are also provided with housings 400 to protect the lifting module 100 and the equipment installed on the side of the lifting module 100 away from the battery swapping platform, such as... Figure 2 and 7 As shown, the lifting module 100 and the moving module 300 are set at 90°.

[0115] This solution employs a modular design, with the frame module comprising a mobile module 300 and a lifting module 100. By positioning the mobile module 300, lifting module 100, and battery swapping platform at different locations, each module can be assembled independently, improving the overall production efficiency of the battery swapping device. The battery swapping platform, located in the central accommodating area 500, utilizes two opposing lifting modules 100 and two opposing mobile modules 300, resulting in a more compact structure. The modules and frame do not overlap in the height direction, reducing the overall height of the battery swapping device. Furthermore, it enables bottom-mounted battery swapping for light trucks, allowing for the complete battery removal and installation using a single swapping device, significantly reducing the cost and improving the efficiency of battery swapping for light trucks.

[0116] In this embodiment, as Figure 2 , Figure 5 and Figure 6 As shown, the battery swapping platform includes a platform base plate 210, a battery swapping module 200, and multiple support modules 250 mounted on the platform base plate 210. The platform base plate 210 is connected to a lifting module 100 so that the platform base plate 210 can be lifted by the lifting module 100. The battery swapping module 200 is used to install the battery onto the vehicle or remove the battery from the vehicle. The support modules 250 are located on both sides of the battery swapping module 200 so that the support modules 250 and the battery swapping module 200 can jointly support the battery. Specifically, there are four support modules 250, distributed on both sides of the platform base plate 210, with two support modules spaced apart on each side, so that they are approximately located at the four corners for optimal performance. The platform base plate 210 is connected to the lifting module 100 and can drive the battery replacement module 200 to rise and fall to cooperate with the vehicle chassis for battery swapping. The platform base plate 210 provides a mounting frame for the battery replacement module 200. The battery replacement module 200 and the support module 250 together provide a load-bearing surface for the battery, so that the battery has a wider contact surface during the replacement process, which can meet the needs of replacing large-size batteries and make the battery replacement process more stable.

[0117] In this embodiment, support modules 250 are respectively disposed on both sides of the battery replacement module 200 along the first direction A. Specifically, two support modules are disposed at intervals on each side, and a predetermined distance is spaced between the support modules 250 and the battery replacement module 200 on each side to form a double-extending receiving area 260. This allows the double extensions of the battery transfer mechanism to lift the battery from under the battery for transfer. The preset width of the double-extending receiving area 260 is not less than the width of the double extensions of the battery transfer mechanism. The battery swapping platform is provided with the double-extending receiving area 260. By arranging this area on both sides of the battery replacement module 200, it facilitates the double extensions of the battery transfer mechanism in picking up and placing batteries relative to the battery replacement module 200, and provides reasonable operational space.

[0118] In this embodiment, the battery replacement module 200 includes a base 220, an unlocking mechanism 230, and a tray 240 disposed on the base 220. The base 220 is connected to the platform base plate 210 and can move relative to the platform base plate 210 along a second direction B perpendicular to the first direction A. The unlocking mechanism 230 is located below the tray 240. The tray 240 has a through hole so that the unlocking mechanism 230 can pass through the through hole to unlock or unlock the battery during operation. The tray 240 provides a supporting surface for the battery. The through hole on the tray 240 provides unlocking space for the unlocking mechanism 230 when unlocking or unlocking the battery, and returns to its original position below the tray 240 when the unlocking mechanism 230 is not in operation, thereby protecting the unlocking mechanism 230 from damage.

[0119] In this embodiment, there are two unlocking mechanisms 230, which are fixed to the base 220 on both sides along the second direction B. By setting two unlocking structures, corresponding to two unlocking points in the battery, the unlocking efficiency is high and the unlocking success rate is high. At the same time, the two unlocking structures correspond to two locking structures on the battery or the vehicle body, making the installation of the battery on the vehicle body more secure and stable.

[0120] In this embodiment, the base 220 is further provided with a vehicle positioning post 280 for positioning the battery. The vehicle positioning post 280 is located on the first side of the battery replacement module 200, and the tray 240 is provided with a battery positioning post 290 for positioning the battery. The battery positioning post 290 is located on the second side of the battery replacement module 200. The first side and the second side are respectively the two sides of the battery replacement module 200 along the first direction A. The vehicle positioning post 280 is used to determine the position between the battery swapping device and the battery swapping vehicle, and the battery positioning post 290 is used for the battery swapping device to position the battery of the battery swapping vehicle. The dual positioning method makes the positioning more accurate, thereby improving the unlocking success rate.

[0121] In another embodiment, the battery positioning posts 290 may also be located on the first side and the second side of the battery replacement module 200, respectively, and the battery positioning posts 290 on the first side and the second side position the battery from the first direction A and the second direction B, respectively.

[0122] In this embodiment, the tray 240 is buoyantly connected to the base 220, and the support module 250 is buoyantly connected to the platform base plate 210. When the battery swapping platform is not carrying a battery, the bearing surfaces of the tray 240 and the support module 250 are at the same height. The buoyant connection of the tray 240 to the base 220 and the buoyant connection of the support module 250 to the platform base plate 210 provides a buffering effect when carrying a battery, while also increasing the contact area between the battery and the tray 240 and support module 250, resulting in higher stability. Furthermore, when not carrying a battery, both are at the same height, and when carrying a battery, the platform is more stable.

[0123] Specifically, the tray 240 can be connected to the base 220 via an elastic element, such as a spring, and the support module 250 can be connected to the platform base plate 210 via an elastic element, such as a spring.

[0124] In this embodiment, the battery replacement module 200 has two support modules 250 on each side, and the support modules 250 are spaced apart along the second direction B. Each support module 250 has a disc-shaped structure. When the battery is supported, the multiple support modules 250 can distribute the force and increase the contact points with the battery, thereby improving the load-bearing stability of the battery and facilitating the replacement of larger batteries.

[0125] In other embodiments, multiple support modules 250 can be flexibly provided on each side of the battery replacement module 200 as needed, or only one support module 250 can be provided on each side. The support module 250 can be disc-shaped or elongated, extending in the second direction B to provide sufficient support surface to the battery. In actual use, the number of support modules 250 is not limited to this.

[0126] As shown in the figure, Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the lifting module 100 includes a lifting frame 110 extending along the second direction B and a lifting mechanism mounted on the lifting frame 110. The lifting mechanism includes a lifting motor 130 and a lifting member 120 disposed on the side wall of the lifting frame 110 facing the battery swapping platform. The lifting member 120 is connected to the battery swapping platform so that the lifting motor 130 can drive the lifting member 120 to move, thereby raising and lowering the battery swapping platform. The lifting frame 110 provides installation space for the lifting mechanism, which enables the raising and lowering of the battery swapping platform.

[0127] In this embodiment, the lifting frame 110 has a hollow cavity, and the lifting motor 130 is disposed within the cavity. Disposing the lifting motor 130 within the cavity helps save space and results in a more compact structure.

[0128] In this embodiment, there are two lifting members 120, which are spaced apart along the second direction B on the side wall of the lifting frame 110. The lifting mechanism also includes a transmission assembly 140 connected to the lifting motor 130. The transmission assembly 140 is located on the side of the lifting frame 110 facing the battery swapping platform and is connected to both lifting members 120, so that the lifting motor 130 can drive both lifting members 120 simultaneously. Through the transmission assembly 140, the lifting motor 130 in the lifting frame 110 can simultaneously drive the two lifting members 120 located on the same lifting frame 110 as the lifting motor 130. The two lifting members 120 can achieve synchronous movement, eliminating the need for two motors for driving, saving resources. By setting two lifting members 120, the lifting force is more balanced, and the lifting process is more stable.

[0129] Among them, such as Figure 3 , Figure 4 As shown, in this embodiment, the transmission assembly 140 includes a slide connected to the lifting motor 130. The lifting motor 130 drives the slide to perform reciprocating linear motion. The slide is connected to a chain, and the chain performs reciprocating selective motion through a sprocket, thereby driving the lifting member 120 to perform reciprocating rotational motion, thus driving the battery swapping platform to rise and fall. To demonstrate the external structure of the sprocket coaxially connected to the lifting member 120 in the transmission assembly 140, Figure 2 , Figure 3 , Figure 7 and Figure 9 In the diagram, the chain of the transmission assembly 140 is not fully shown. In the actual design, the chain of the transmission assembly 140 is fitted onto the sprocket.

[0130] In this embodiment, as Figure 2 , Figure 7 and Figure 8 As shown, the mobile module 300 includes a mobile frame 310 extending along a first direction A and two traveling members 320 spaced apart below the mobile frame 310 along the first direction A. Each lifting module 100 has an end receiving area on the side opposite to the battery swapping platform. The end receiving area is equipped with a traveling drive motor 351 to drive the traveling members 320 to move the frame module. The traveling drive motor 351 is located in the end receiving area, which improves space utilization and makes the overall structure more compact.

[0131] In other embodiments, the number of walking components 320 is not limited to this, and more than two can be provided as needed.

[0132] In this embodiment, the mobile frame 310 has a traveling member 320 at both its head and tail ends along the first direction A. A traveling drive motor 351 is also provided at each of the head and tail ends of the mobile frame 310. Each traveling drive motor 351 drives two traveling members 320 located at the head or tail end. By providing traveling members 320 at both ends of the mobile frame 310, structurally, the force points of the mobile frame 310 are located at both ends during movement, making it more stable and improving its load-bearing capacity. Furthermore, providing traveling drive motors at both ends facilitates control over the accuracy of the battery swapping equipment's movement.

[0133] In this embodiment, as Figure 8 As shown, a synchronization component 353 is provided between two traveling components 320 located at the head or tail end. The synchronization component 353 is connected to the traveling drive motor 351 via a gear set 352. The gear set 352 includes a first gear connected to the traveling drive motor 351 and a second gear connected to the synchronization component 353. The first and second gears are arranged vertically from top to bottom and mesh with each other. The traveling drive motor 351 provides power to the traveling components 320 through the synchronization component 353 and the gear set 352, achieving stable operation of the battery swapping device while saving space resources. The traveling components 320 can maintain synchronous operation, improving the reliability and stability of the mobile module 300 during operation.

[0134] In this embodiment, as Figure 7 As shown, a guide member is provided below one of the moving frames 310, located between the two traveling members 320 at the front and rear ends; a support member (not shown in the figure) is also provided below the other moving frame 310, located between the two traveling members 320 at the front and rear ends and corresponding to the guide member. By providing a guide member below one frame, the movement of the battery swapping device can be guided, ensuring that the battery swapping device moves along a preset trajectory. By providing a support member below the other moving frame 310, the overall load-bearing capacity of the battery swapping device can be improved, increasing the weight it can bear.

[0135] In this embodiment, as Figure 7As shown, the mobile frame 310 includes a first region 371, a second region 372, and a third region 373 connected along one side of a first direction A. The first height of the first region 371 and the third region 373 in the vertical direction is higher than the second height of the second region 372 in the vertical direction. The length of the second region 372 extending along the first direction A is not less than the distance between the outermost edges of the two support modules 250 arranged along the first direction A. The height of the second region 372 is lower than that of the first region 371 and the third region 373. The second region 372 can provide more height space than the first region 371 and the third region 373, ensuring more sufficient installation space for the battery swapping platform. This helps to reduce the overall height of the battery swapping device, thereby enabling the battery swapping equipment to meet the battery swapping needs of light trucks with limited bottom space.

[0136] In this embodiment, as Figure 2 and Figure 7 As shown, the battery swapping platform includes a platform base plate 210, a battery replacement module 200 mounted on the platform base plate 210, and multiple support modules 250. The battery replacement module 200 includes a base 220 and a tray 240 mounted on the base 220. The bearing surfaces of the tray 240 and the support modules 250 are both lower than a first height and higher than a second height. This lower height and higher height of the bearing surfaces of the tray 240 and the support modules 250 helps to reduce the overall height of the battery swapping device, while ensuring that the second area of ​​the moving frame does not interfere with the battery.

[0137] In this embodiment, the battery swapping platform includes a battery replacement module 200, which includes a base 220. The base 220 has a vehicle positioning post 280 for positioning with the vehicle. The side of the base 220 with the vehicle positioning post 280 extends outwards to above the movable frame 310 of the second region 372. Since the height of the second region 372 is relatively low, extending the base 220 to this location results in higher space utilization and a more compact overall structure. This meets the requirements for large-size battery installation and removal while ensuring the overall structure of the battery swapping equipment is not excessively large, thus making the battery swapping equipment structure compact.

[0138] Specifically, in this embodiment, the base 220 includes two relatively independent shelves, namely a first shelf and a second shelf, which are connected to the platform base plate 210 via linear movement mechanisms. The first shelf is floatingly connected to the tray 240 via a spring and is used for positioning and supporting the battery, while the second shelf is equipped with a vehicle positioning post 280 and an unlocking mechanism 230 for positioning the vehicle. The two relatively independent shelves move horizontally under the drive of their respective linear movement mechanisms to complete the installation and removal of the battery relative to the vehicle.

[0139] In this embodiment, as Figure 9 As shown, a sliding assembly is provided between the moving module 300 and the battery swapping platform. The sliding assembly includes a guide rail and a slider 275 that cooperate with each other. The moving frame 310 is provided with guide rails in both the first region 371 and the third region 373, and the battery swapping platform is provided with sliders 275 at the corresponding locations. Through the cooperation of the guide rails and sliders 275, the stability of the battery swapping platform during ascent and descent can be ensured. Furthermore, due to the limiting effect of the cooperation between the guide rails and sliders 275, it can be ensured that the battery swapping platform will not deviate in other directions during ascent and descent.

[0140] In other embodiments, a sliding assembly is provided between the mobile module 300 and the battery swapping platform. The sliding assembly includes a guide rail 360 and a slider 275 that cooperate with each other. The mobile frame 310 is provided with sliders 275 in both the first region 371 and the third region 373, and the battery swapping platform is provided with guide rails 360 in the corresponding locations.

[0141] In this embodiment, as Figure 7 and Figure 10 The mobile frame 310 is also provided with a first cable trough 380 extending along the first direction A. The first cable trough 380 is provided with a first inlet and a first outlet. The first inlet is used to allow the first cable 381 to enter the first cable trough 380. The first outlet is located at the beginning and end of the mobile frame 310 to allow the first cable 381 in the first cable trough 380 to be led out to supply power to the equipment in the frame module.

[0142] In this design, the first cable tray 380 is located inside the movable frame 310, providing ample space for cable routing. Cables running from inside the movable frame 310 do not occupy external space, resulting in a compact structure. Furthermore, the cables will not collide with external parts, making the design safer.

[0143] In this embodiment, as Figure 10 As shown, the battery swapping platform also includes a second cable trough 295 extending along the first direction A. The second cable trough 295 has a second inlet and a second outlet. The second inlet allows the second cable 296 to enter the second cable trough 295, and the second outlet, located in the middle of the battery swapping platform, allows the second cable 296 within the second cable trough 295 to be led out to supply power to the equipment within the battery swapping platform. The second cable trough 295 provides space for the second cable 296, resulting in a more organized layout that avoids interference with other moving parts, and a more stable power supply to the battery swapping device.

[0144] In this embodiment, as Figure 10As shown, the second cable tray 295 is adjacent to the first cable tray 380, and the second inlet port is correspondingly arranged to the first outlet port, so that the second cable 296 is laid in the first cable tray 380 and enters the second cable tray 295 from the first outlet port and the second inlet port. The second cable tray 295 is adjacent to the first cable tray 380 and the second inlet port is corresponding to the first outlet port, so that the cable can pass through the first cable tray 380 and then into the second cable tray 295, thus extending the cable arrangement space.

[0145] In this embodiment, as Figure 2 and Figure 10 As shown, an arched connector is provided between the second inlet and the first outlet. The arched connector is hollow to allow the second cable to pass through. The arched connector 600 provides a transition for the second cable 296 to pass through the first cable tray 380 and the second cable tray 295, thus protecting the second cable 296. In this embodiment, the arched connector 600 is a cable chain.

[0146] In this embodiment, Figure 10 As shown, each lifting module 100 has an end receiving area on the side away from the battery swapping platform. The frame module also includes a first junction box 700, which is disposed in the end receiving area and located above the synchronization component 353. The first junction box 700 has a first inlet terminal and multiple first outlet terminals. The first inlet terminal is used to connect to the first low-voltage cable in the first cable 381, and the multiple first outlet terminals are respectively used to connect to the low-voltage equipment in the frame module.

[0147] In this embodiment, Figure 10 As shown, the battery swapping platform also includes a second junction box 297, which is located between two support modules 250 on one side of the battery swapping module 200. The second junction box 297 has a second inlet terminal and multiple second outlet terminals. The second inlet terminal is used to connect to the second low-voltage cable in the second cable 296, and the multiple second outlet terminals are used to connect to the low-voltage equipment within the battery swapping platform. The first junction box 700 and the second junction box 297 facilitate the connection of low-voltage equipment and cables in different locations.

[0148] Of course, in other embodiments, the first junction box 700 or the second junction box 297 may be preferably set at other locations on the battery swapping platform to meet the needs of cable access and positioning.

[0149] This embodiment also provides a battery swapping station that employs the modular battery swapping device described above. The battery swapping device can travel within a pre-defined battery swapping channel within the station and proceed to a swapping point to swap batteries for vehicles. By employing the aforementioned battery swapping device, the station can meet the battery swapping requirements of light trucks, thereby enhancing product competitiveness.

[0150] In this embodiment, limiting mechanisms are provided at both ends of the battery swapping channel to ensure that the battery swapping device can only move within the battery swapping channel. These limiting mechanisms ensure that the battery swapping device does not deviate from the battery swapping channel, thereby protecting it from collisions with nearby objects.
