[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to patent application 202311032747.0, filed on August 16, 2023, entitled “Position Adjustment Device, Battery Exchange Station, and Battery Exchange Method,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The embodiments of the present application relate to the field of battery swapping technology, and more specifically, to a position adjustment device, a battery swapping station, and a battery swapping method. Background Art

[0004] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. In this context, electric vehicles, due to their energy-saving and environmentally friendly advantages, have become a crucial component of this sustainable development. Battery swapping is a crucial method for replenishing energy for electric vehicles, allowing them to quickly recharge when their batteries are running low.

[0005] Before replacing a vehicle's battery, it must be parked on a battery swap platform and positioned using a positioning device on the platform. However, existing positioning devices can only adjust for a single vehicle model and are difficult to achieve compatibility with multiple models. Therefore, finding a positioning device that is compatible with different vehicle models is a pressing technical issue.

[0006] Summary of the Invention

[0007] The present application provides a position adjustment device, a battery swap station and a battery swap method, which are compatible with different vehicle models and are conducive to the development and promotion of battery swap stations.

[0008] In a first aspect, a position adjustment device is provided, which is used for vehicle battery replacement. The position adjustment device includes at least one position adjustment mechanism, and the position adjustment mechanism is configured to be movable along at least one of a first direction or a second direction, wherein the first direction and the second direction are respectively the vehicle length direction and the vehicle width direction.

[0009] The embodiment of the present application provides a position adjustment device, which includes at least one position adjustment mechanism. By moving the position adjustment mechanism along at least one of the vehicle length direction or the vehicle width direction, when different types of battery-swapping vehicles need to be replaced, the position adjustment device can be compatible with and carry different types of battery-swapping vehicles, thereby adjusting the battery-swapping posture or position of different types of battery-swapping vehicles to facilitate subsequent battery-swapping operations. Therefore, the technical solution of the present application is compatible with different vehicle models and is conducive to the development and promotion of battery-swapping stations.

[0010] In one possible implementation, the position adjustment mechanism includes a first position adjustment mechanism that is movable along the first direction. By setting the first position adjustment mechanism movable along the first direction, the position of the first position adjustment mechanism can be adjusted according to the length of different battery-swapping vehicles, so that the battery-swapping vehicle or the wheels of the battery-swapping vehicle are positioned on the first position adjustment mechanism, thereby facilitating the first position adjustment mechanism to adjust the battery-swapping position of the battery-swapping vehicle.

[0011] In one possible implementation, the position adjustment mechanism further includes a moving assembly, which is connected to the first position adjustment mechanism and is used to move the first position adjustment mechanism to a target position along the first direction. By providing the moving assembly, the first position adjustment mechanism can be moved in the first direction, thereby achieving compatibility with battery-swap vehicles of different lengths.

[0012] In one possible implementation, the moving assembly includes a driving member and a connecting member, one end of the connecting member being connected to the driving member and the other end being connected to the first position adjustment mechanism, so as to drive the first position adjustment mechanism to move along the first direction under the drive of the driving member. In this way, the driving member can drive the connecting member to move, thereby driving the first position adjustment mechanism to move along the first direction.

[0013] In one possible implementation, the first position adjustment mechanism includes a first support platform, which is used to support the wheel of the battery-swap vehicle. In this way, the first support platform is movable along a first direction, so that the first support platform can be moved along the first direction to correspond to the wheel of the battery-swap vehicle.

[0014] In one possible implementation, the first support platform is configured to be liftable. Thus, after the battery swap vehicle is moved to the battery swap position by the first support platform, the wheels can be lifted by the first support platform to lift the battery swap vehicle, facilitating subsequent battery swap operations.

[0015] In one possible implementation, the first support platform includes wheel locating grooves. Thus, after the battery-swapping vehicle is moved to the battery-swapping position via the first support platform, the wheel locating grooves secure the vehicle to the first support platform, preventing the vehicle from moving during lifting, thereby improving the reliability of the battery-swapping process.

[0016] In one possible implementation, the first position adjustment mechanism can be moved in a range of 180 mm to 400 mm in the first direction, which facilitates adaptation to battery-swap vehicles of different lengths. Optionally, the first position adjustment mechanism can be moved in a range of 190 mm to 210 mm in the first direction, which facilitates adaptation to battery-swap vehicles of different lengths while reducing the cost increase caused by the large movable range of the first position adjustment mechanism in the first direction, thereby facilitating cost control.

[0017] In one possible implementation, the position adjustment mechanism further includes a second position adjustment mechanism, and the first position adjustment mechanism and the second position adjustment mechanism are sequentially arranged along the first direction, and the first position adjustment mechanism and the second position adjustment mechanism are respectively used to correspond to at least two wheels of the battery-swap vehicle at different positions along the first direction. In this way, the position adjustment device can be applicable to vehicles including two pairs of wheels and more than two pairs of wheels. By setting the first position adjustment mechanism and the second position adjustment mechanism, more types of battery-swap vehicles can be compatible.

[0018] In one possible implementation, the first position adjustment mechanism is used to correspond to the front wheel position of the battery-swap vehicle, and the second position adjustment mechanism is used to correspond to the rear wheel position of the battery-swap vehicle.

[0019] In the above solution, when the battery position in the battery-swap vehicle is positioned based on the front wheels, by adjusting the position of the first position adjustment mechanism in the first direction, the front wheels of the vehicle can be parked in a predetermined position, thereby facilitating battery swapping of the battery-swap vehicle at the predetermined position. In addition, when the first direction dimension of the first position adjustment mechanism is smaller than the first direction dimension of the second position adjustment mechanism, providing the first position adjustment mechanism with a movable shape along the first direction can help reduce production costs.

[0020] In a possible implementation, the position of the second position adjustment mechanism along the first direction is fixed, and the second position adjustment mechanism includes a second supporting platform, and the size of the second supporting platform along the first direction is larger than the size of the first supporting platform of the first position adjustment mechanism along the first direction.

[0021] In the above scheme, the first position adjustment mechanism includes a first load-bearing platform, and the second position adjustment mechanism includes a second load-bearing platform. After the first position adjustment mechanism moves to the target position, the battery-swap vehicle can be parked on the first load-bearing platform and the second load-bearing platform. The battery-swap vehicle is supported by the first load-bearing platform and the second load-bearing platform, and the position of the battery-swap vehicle in the second direction is adjusted on the first load-bearing platform and the second load-bearing platform. The first position adjustment mechanism is movable along the first direction, and the position of the second position adjustment mechanism along the first direction is fixed. The size of the second load-bearing platform along the first direction is larger than the size of the first load-bearing platform along the first direction. In this way, the structural complexity of the position adjustment device can be reduced while being compatible with multiple types of battery-swap vehicles, which is conducive to reducing production costs.

[0022] In one possible implementation, the second supporting platform is used to support at least two wheels of the battery-swapping vehicle along the first direction. In the case where the battery-swapping vehicle has three or more pairs of wheels, the second supporting platform can support at least two wheels of the battery-swapping vehicle in the first direction. In this way, through the provision of the second supporting platform, the position adjustment device can be compatible with more types of battery-swapping vehicles, such as non-passenger vehicles including three or more pairs of wheels.

[0023] In one possible implementation, along the first direction, the size of the second support platform is 1000mm to 1500mm; alternatively, along the first direction, the size of the second support platform is 1100mm to 1300mm. This makes it easier for the position adjustment device to be compatible with more battery-swap vehicles of different lengths.

[0024] In one possible implementation, the second position adjustment mechanism is movable along the first direction. Both the first and second position adjustment mechanisms are movable along the first direction. This helps further increase the adjustment range of the position adjustment mechanism in the first direction, making it applicable to more types of battery-swap vehicles. It also increases the flexibility of the position adjustment mechanism, facilitating flexible adjustment of the positions of the first and second position adjustment mechanisms in the first direction according to actual conditions.

[0025] In one possible implementation, the movable range of the first position adjustment mechanism is greater than the movable range of the second position adjustment mechanism. This allows the first position adjustment mechanism to have a larger movable range in the first direction, while the second position adjustment mechanism has a smaller movable range in the second direction. This can reduce production costs while ensuring compatibility with a wider range of battery-swap vehicles.

[0026] In one possible implementation, the position adjustment device further includes a position calibration mechanism configured to move the battery-swapping vehicle to a preset position along the second direction. After the battery-swapping vehicle enters the battery-swapping platform, the battery-swapping vehicle may deviate from the preset position. The position calibration mechanism can be used to move the battery-swapping vehicle to the preset position, thereby facilitating subsequent battery-swapping operations.

[0027] In one possible implementation, the position calibration mechanism includes a push rod mechanism, which is configured to push the battery swap vehicle to the preset position along the second direction. After the battery swap vehicle enters the battery swap platform, the battery swap vehicle may have a skewed body or a body biased toward one side of the second direction of the battery swap platform. The push rod mechanism can be used to straighten the body of the battery swap vehicle, or the battery swap vehicle can be moved along the second direction to the preset position, thereby facilitating subsequent battery swap operations.

[0028] In one possible implementation, the first position adjustment mechanism includes a first supporting platform, and the position adjustment device also includes a second supporting platform. The first supporting platform and the second supporting platform are respectively used to support the wheels of the battery-exchange vehicle at different positions along the first direction. At least one of the first supporting platform and the second supporting platform is provided with multiple rollers arranged along the second direction.

[0029] In the above solution, multiple rollers are arranged along the second direction. In this way, under the action of the push rod mechanism, the multiple rollers can transport the battery-swap vehicle to a preset position along the second direction.

[0030] In one possible implementation, the push rod mechanism is disposed on at least one of the first and second load platforms to push the battery-swap vehicle to the preset position on the first and / or second load platforms. This facilitates pushing the battery-swap vehicle and eliminates the need for additional installation space for the push rod mechanism on the battery-swap platform, thereby improving the space utilization of the battery-swap platform.

[0031] In one possible implementation, at least one of the first and second support platforms is provided with two rows of rollers facing each other along the first direction. The two rows of rollers are arranged at an angle relative to each other to form positioning grooves for securing the wheels. Thus, after the battery-swap vehicle moves to a preset position, the positioning grooves formed by the rollers can be used to position and secure the battery-swap vehicle.

[0032] In one possible implementation, the size of the first carrier along the second direction and / or the size of the second carrier along the second direction is 2000mm to 2300mm; optionally, the size of the first carrier along the second direction and / or the size of the second carrier along the second direction is 2000mm to 2200mm. This facilitates adaptation to battery-swap vehicles of different widths and wheel sizes.

[0033] In one possible implementation, the position adjustment device includes at least three position adjustment mechanisms, which are arranged sequentially along the first direction, and at least two of the at least three position adjustment mechanisms are used to correspond to wheels arranged at different positions of the battery-swapping vehicle along the first direction. In this way, it is convenient to select the corresponding position adjustment mechanism to adjust the battery-swapping position of the battery-swapping vehicle according to the length of the battery-swapping vehicle.

[0034] In one possible implementation, the position adjustment device further includes an adjustment mechanism configured to move the battery-swapping vehicle to a preset position along the second direction, where the second direction is perpendicular to the first direction. After the battery-swapping vehicle enters the battery-swapping platform, it may deviate from the preset position. The adjustment mechanism can be used to move the battery-swapping vehicle to the preset position, thereby facilitating subsequent battery-swapping operations.

[0035] In a second aspect, the present application provides a battery swap station, comprising the position adjustment device in the first aspect and any possible implementation thereof.

[0036] On the third aspect, the present application provides a battery swapping method, including: obtaining information of a battery swapping vehicle; and adjusting a position adjustment device according to the information of the battery swapping vehicle before the battery swapping vehicle enters a battery swapping platform.

[0037] The above solution can be applied to different types of battery-swap vehicles, and thus the position adjustment device can be adjusted according to the information of the battery-swap vehicle.

[0038] In one possible implementation, before the battery-swapping vehicle enters the battery-swapping platform, adjusting the position adjustment device based on the battery-swapping vehicle's information includes: moving the positions of several position adjustment mechanisms to correspond to the battery-swapping vehicle's information; or determining several position adjustment mechanisms corresponding to the battery-swapping vehicle's information. This facilitates adjusting the battery-swapping positions of different types of battery-swapping vehicles based on the specific settings of the position adjustment device and the battery-swapping vehicle's information.

[0039] In one possible implementation, the battery swap method further includes: after the battery swap vehicle is parked on the position adjustment device, controlling the position adjustment device to adjust the position of the battery swap vehicle. In this way, after the battery swap vehicle enters the battery swap platform, the position adjustment device is controlled to adjust the position of the battery swap vehicle to facilitate subsequent battery swap operations.

[0040] The present application provides a position adjustment device, which includes at least one position adjustment mechanism. By moving the position adjustment mechanism along at least one of the vehicle length direction or the vehicle width direction, when different types of battery-swapping vehicles need to be replaced, the position adjustment device can be compatible with and carry different types of battery-swapping vehicles, thereby adjusting the battery-swapping posture or position of different types of battery-swapping vehicles to facilitate subsequent battery-swapping operations. Therefore, the technical solution of the present application is compatible with different vehicle models and is conducive to the development and promotion of battery-swapping stations.

DETAILED DESCRIPTION

[0057] The following detailed description of the embodiments of the present application is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present application, but are not intended to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0058] In the description of this application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", "third", etc. are only used to distinguish different objects, and are not used to describe a specific order or a primary and secondary relationship. "Vertical" is not strictly perpendicular, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0059] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0060] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0061] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0062] With the increase in the number of electric vehicles, the requirements for electric vehicles are also getting higher and higher. During the driving process of electric vehicles, the power will gradually decrease. In current technology, it is necessary to regularly charge the battery in the vehicle through a charging pile to ensure that the battery has sufficient power to maintain the continuous operation of the vehicle. However, since the battery capacity is generally large, each charging time will be long. During this long charging time, the user cannot use the vehicle, which will seriously affect the user's driving experience. Therefore, battery swap stations came into being. They can directly replace the low-power battery in the vehicle with a fully charged battery. The entire battery swap process is short, which can greatly save battery charging time, will not affect the user's use of the vehicle, and greatly improve the user's driving experience.

[0063] Before replacing a vehicle's battery, it must be parked on a battery swap platform and positioned using the platform's position adjustment device. However, some position adjustment devices can only adjust for a single vehicle type, making it difficult to achieve compatibility with multiple models, hindering the development and promotion of battery swap stations.

[0064] In view of this, the present application provides a position adjustment device for vehicle battery swapping, the position adjustment device including at least one position adjustment mechanism that is movable along at least one of a first direction or a second direction, the first direction and the second direction being the vehicle length direction and the vehicle width direction, respectively. The moved position adjustment mechanism can correspond to the position of the battery swapping vehicle after entering the battery swapping station, so as to facilitate subsequent position adjustment of the battery swapping vehicle. In this way, the position adjustment device can be compatible with different types of battery swapping vehicles, which is conducive to the development and promotion of battery swapping stations.

[0065] FIG1 is a schematic structural diagram of a battery swap station 100 provided in one embodiment of the present application.

[0066] The battery swap station 100 may include a battery rack 101. The battery rack 101 may be configured with multiple batteries. The battery rack 101 may include a battery charging compartment and a battery buffer. Batteries may be stored in the battery charging compartment so that they can be charged. The battery buffer may be used to temporarily store depleted batteries that have been replaced from a vehicle.

[0067] In addition to the battery rack 101, the battery swap station 100 may also include a palletizer 102 and a mobile battery swap device (not shown in Figure 1). The mobile battery swap device can transport the depleted batteries replaced from the vehicle to the battery cache device, and the palletizer 102 transports the depleted batteries in the battery cache device to the battery rack 101, so that the battery rack 101 can charge the depleted batteries. In addition, the palletizer 102 can also transport the fully charged batteries on the battery rack 101 to the mobile battery swap device, which carries the fully charged batteries to the vehicle and installs the fully charged batteries on the vehicle. As an example, the mobile battery swap device can be a rail guided vehicle (RGV) or an automated guided vehicle (AGV).

[0068] The battery swap station 100 may also include a battery swap platform 200. Figure 2 shows a schematic diagram of a battery swap vehicle 1 traveling on the battery swap platform 200. On the battery swap platform 200, the mobile battery swap device can replace the battery on the battery swap vehicle 1. The x direction in Figures 1 and 2 can be the driving direction of the battery swap vehicle 1 on the battery swap platform 200 or the length direction of the battery swap vehicle 1, and the y direction can be the driving direction of the mobile battery swap device on the battery swap platform 200 or the width direction of the battery swap vehicle 1. The mobile battery swap device can be moved along the y direction to the vicinity of the battery swap vehicle 1 through the guide rails on the battery swap platform 200.

[0069] The battery swap station 100 may further include a position adjustment device 400 , which is used to adjust the battery swap vehicle 1 to the battery swap position and fix it after the battery swap vehicle 1 enters the battery swap platform 200 .

[0070] The battery swap station 100 may also include a vehicle lifting device 300, which is used to lift the battery swap vehicle 1 after the battery swap vehicle 1 is fixed at the battery swap position. In some application scenarios, the battery is installed on the chassis of the battery swap vehicle 1. During the battery swap process, the vehicle must first be lifted, and then the battery swap device must be moved to the bottom of the battery swap vehicle 1 to replace the battery in the chassis.

[0071] As an example, in the embodiment shown in Figures 1 and 2, the battery swap platform 200 may include a vehicle lifting device 300, a front ramp 104, a rear ramp 103, and a position adjustment device 400. The battery swap vehicle 1 can travel from the rear ramp 103 toward the front ramp 104, as shown in Figure 2. Along the driving direction of the battery swap vehicle 1, the position adjustment device 400 can be located between the front ramp 104 and the rear ramp 103. The position adjustment device 400 can be used to adjust and position the battery swap vehicle 1, thereby positioning the battery swap vehicle 1 in the x-direction and the y-direction so that the battery swap vehicle 1 can be fixed relative to the battery swap platform 200. When the battery swap platform 200 completes the positioning of the battery swap vehicle 1, the vehicle lifting device 300 can be triggered to lift the battery swap vehicle 1.

[0072] After the battery swap vehicle 1 is lifted, the mobile battery swap device can be moved to the bottom of the battery swap vehicle 1. After the mobile battery swap device is aligned with the battery in the chassis of the battery swap vehicle 1, the mobile battery swap device can remove the low-charged battery in the vehicle. Then, the mobile battery swap device moves to the vicinity of the battery cache device and places the low-charged battery in the battery cache device. The palletizer 102 obtains the fully charged battery from the battery rack 101 in advance and waits for the mobile battery swap device at the battery cache device. After the mobile battery swap device stores the low-charged battery in the battery cache device, the palletizer 102 places the fully charged battery into the mobile battery swap device that has no battery, and transports the low-charged battery in the battery cache device to the battery rack 101 for charging. Furthermore, the mobile battery swap device obtains the fully charged battery to be installed from the palletizer 102, and carries the fully charged battery to be installed to the bottom of the battery swap vehicle 1 again, and loads the battery to be installed into the chassis of the battery swap vehicle 1.

[0073] Optionally, a locking mechanism is provided in the chassis of the battery-swap vehicle 1, and a locking portion corresponding to the locking mechanism is provided in the battery. The locking mechanism can be used to lock the locking portion so that the battery can be locked and installed on the chassis of the battery-swap vehicle 1; correspondingly, the locking structure can also be configured to release the lock of the locking portion so that the battery can be unlocked and removed from the chassis of the battery-swap vehicle 1. During the process of removing and installing the battery by the above-mentioned mobile battery-swap device, the mobile battery-swap device can press the battery upward to unlock and lock the locking portion in the battery and the locking mechanism in the battery-swap vehicle 1, thereby completing the removal and installation of the battery.

[0074] After the battery-swapping vehicle 1 completes the battery swap, the mobile battery-swapping device exits the battery-swapping platform 200 , and the vehicle lifting device 300 can lower the battery-swapping vehicle 1 back to the battery-swapping platform 200 .

[0075] FIG3 is a schematic diagram of a battery swap platform according to an embodiment of the present application. As shown in FIG3 , the battery swap platform 200 includes a position adjustment device 400 .

[0076] As shown in FIG3 , an embodiment of the present application provides a position adjustment device 400, which is used for vehicle battery replacement. The position adjustment device 400 includes at least one position adjustment mechanism 400a, which is configured to be movable along at least one of a first direction or a second direction. The first direction and the second direction may be the vehicle length direction and the vehicle width direction, respectively. The position adjustment device 400 can adjust its position to correspond to carrying different types of battery replacement vehicles 1. The different types of battery replacement vehicles 1 may differ in at least one of the vehicle length and vehicle width dimensions, and are used for subsequent vehicle position adjustment.

[0077] The position of the position adjustment mechanism 400a is adjustable. For example, the position of the position adjustment mechanism 400a is adjustable along a first direction but not along a second direction. For another example, the position of the position adjustment mechanism 400a is adjustable along both the first direction and the second direction. For another example, the position of the position adjustment mechanism 400a is adjustable along the second direction but not along the first direction.

[0078] The first direction is different from the second direction. For example, the first direction may be perpendicular to the second direction.

[0079] The position adjustment mechanism 400a is configured to carry the battery-swapping vehicle 1. That is, after the battery-swapping vehicle 1 enters the battery-swapping platform, it can be parked on the position adjustment mechanism 400a. The position adjustment mechanism 400a can be used to adjust, position, and fix the position of the battery-swapping vehicle 1.

[0080] Different types of battery-swap vehicles 1 may differ in at least one of vehicle length and vehicle width. For example, different types of battery-swap vehicles 1 may include passenger vehicles and logistics vehicles, each with different vehicle lengths and vehicle widths. For another example, logistics vehicles may include multiple different types of logistics vehicles, each with different vehicle lengths, vehicle widths, and number of wheels, due to different uses or designs.

[0081] The position of the position adjustment mechanism 400a is adjustable, so the position adjustment mechanism 400a can carry different types of battery-swap vehicles 1.

[0082] Optionally, the position adjustment device 400 further includes a power mechanism, which can be used to provide a power source for the operation of some components in the position adjustment mechanism.

[0083] The embodiment of the present application provides a position adjustment device 400, including a position adjustment mechanism 400a that can be adjusted to correspond to carrying different types of battery-swap vehicles 1, and the different types of battery-swap vehicles 1 are different in at least one of vehicle length and vehicle width. In this way, when different types of battery-swap vehicles 1 need to be replaced, the position adjustment device 400 can be compatible with and carry different types of battery-swap vehicles 1, so that the battery-swap positions of different types of battery-swap vehicles 1 can be adjusted to facilitate subsequent battery-swap operations. Therefore, the technical solution of the embodiment of the present application can be compatible with different vehicle models, which is conducive to the development and promotion of battery-swap stations.

[0084] In some embodiments, the position adjustment mechanism 400 a includes a first position adjustment mechanism 410 , which is movable along a first direction.

[0085] The first direction is the length direction of the battery-swapping vehicle 1, and may also be the traveling direction of the battery-swapping vehicle 1. For example, in conjunction with Figures 1 to 3 , the first direction may be the x direction in the figure.

[0086] Because different types of battery-swap vehicles 1 have different lengths or widths, after the battery-swap vehicles 1 enter the battery-swap platform 200, their parking positions on the battery-swap platform 200 are different, and the positions of the corresponding position adjustment mechanisms 400a are also different. For example, as shown in Figures 1 to 3, after entering the battery-swap platform 200, the front wheels of the longer battery-swap vehicle 1 are closer to the front ramp 104 relative to the front wheels of the shorter battery-swap vehicle 1, and / or the rear wheels of the longer battery-swap vehicle 1 are closer to the rear ramp 104 relative to the rear wheels of the shorter battery-swap vehicle 1.

[0087] By setting the first position adjustment mechanism 410 movable along the first direction, the position of the first position adjustment mechanism 410 in the first direction can be adjusted according to the vehicle length of different battery-swap vehicles 1, so that the battery-swap vehicle 1 or the wheels of the battery-swap vehicle 1 can be located on the first position adjustment mechanism 410, thereby facilitating the first position adjustment mechanism 410 to adjust the battery-swap position of the battery-swap vehicle 1.

[0088] FIG4 is a schematic diagram of a position adjustment device according to an embodiment of the present application. In some embodiments, as shown in FIG4 , the position adjustment mechanism 400a includes a moving assembly 500 connected to the first position adjustment mechanism 410 and configured to move the first position adjustment mechanism 410 to a target position along a first direction.

[0089] 4 , the moving assembly 500 is located at the end of the first position adjustment mechanism 410 along the first direction. This facilitates installation of the moving assembly 500 and facilitates connection between the moving assembly 500 and the first position adjustment mechanism 410 to move the first position adjustment mechanism 410 along the first direction.

[0090] The target position of the first position adjustment mechanism 410 can be the position of the first position adjustment mechanism 410 obtained by the control system of the battery swap station 100 based on the vehicle information of the battery swap vehicle 1. When the first position adjustment mechanism 410 is at the target position, the battery swap vehicle 1 or the wheels of the battery swap vehicle 1 are located on the first position adjustment mechanism 410.

[0091] For example, when the first position adjustment mechanism 410 is used to support the wheels of the battery-swap vehicle 1, the target position of the first position adjustment mechanism 410 corresponds to the wheel position of the battery-swap vehicle 1 after it enters the battery-swap platform 200; when the first position adjustment mechanism 410 is used to support the chassis of the battery-swap vehicle 1, the target position of the first position adjustment mechanism 410 corresponds to the chassis position of the battery-swap vehicle 1 after it enters the battery-swap platform 200.

[0092] By setting up the moving component 500, the first position adjustment mechanism 410 can be moved in the first direction, thereby enabling the first position adjustment mechanism 410 to be compatible with battery-swap vehicles 1 of different vehicle lengths.

[0093] Figure 5 is an enlarged schematic diagram of area A in Figure 4. Figure 6 is a schematic diagram of a position adjustment device 400 from another perspective according to an embodiment of the present application. In some embodiments, as shown in Figures 5 and 6, the moving assembly 500 includes a driving member 510 and a connecting member 520. One end of the connecting member 520 is connected to the driving member 510, and the other end of the connecting member 510 is connected to the first position adjustment mechanism 410, so that the first position adjustment mechanism 410 is driven by the driving member 510 to move along the first direction.

[0094] Optionally, the connecting member 520 extends along the first direction. Along the first direction, one end of the connecting member 520 is connected to the first position adjustment mechanism 410 , and the other end is connected to the output end of the driving member 510 .

[0095] Optionally, the connecting member 520 includes a screw and a spiral transmission member, one end of the screw is connected to the driving member 510 via the spiral transmission member, and the other end is connected to the first position adjustment mechanism 410. When the driving member 510 rotates, it can drive the spiral transmission member to rotate, and the spiral rotation member can drive the screw to move in the first direction, and the screw can drive the first position adjustment mechanism 410 to move in the first direction.

[0096] The driving member 510 may be a motor, which provides a power source for the movement of the first position adjustment mechanism 410 .

[0097] Optionally, when the first position adjustment mechanism 410 moves to the target position, the driving member 510 stops rotating, and then the connecting member 520 stops moving, and the first position adjustment mechanism 410 can be fixed at the target position.

[0098] In this embodiment, the movement of the first position adjustment mechanism 410 in the first direction is achieved by disposing the driving member 510 and the connecting member 520 .

[0099] Optionally, the moving assembly 500 includes a guide rail, the first position adjustment mechanism 410 is disposed on the guide rail, and the driving member 510 is connected to the first position adjustment mechanism 410 to drive the first position adjustment mechanism 410 to move on the guide rail.

[0100] A guide rail can be provided on the battery swap platform 200 and extend along a first direction to facilitate movement of the first position adjustment mechanism 410 along the guide rail. The provision of the guide rail can reduce the risk of the first position adjustment mechanism 410 shifting during movement, thereby improving the accuracy of the position of the first position adjustment mechanism 410 and reducing the risk of the first position adjustment mechanism 410 shifting in a second direction during movement.

[0101] Optionally, a first locking portion is provided on the guide rail, and a second locking portion is provided on the first position adjustment mechanism 410. The first locking portion cooperates with the second locking portion to fix the first position adjustment mechanism 410 on the guide rail when the first position adjustment mechanism 410 moves to the target position.

[0102] Optionally, the first locking portion can be a groove provided on the wall of the guide rail facing the first position adjustment mechanism 410, and the second locking portion can be a stud provided on the wall of the first position adjustment mechanism 410 facing the sliding rail. During the movement of the first position adjustment mechanism 410, the stud is located inside the wall of the first position adjustment mechanism 410. After the first position adjustment mechanism 410 moves to the target position, the stud protrudes from the wall of the first position adjustment mechanism 410 and is inserted into the groove, thereby achieving the fixation of the first position adjustment mechanism 410 on the guide rail.

[0103] Optionally, a sensor is provided on the first position adjustment mechanism 410 to detect the current position of the first position adjustment mechanism 410 .

[0104] FIG7 is a schematic diagram of a position adjustment device according to an embodiment of the present application. In some embodiments, as shown in FIG5 and FIG7 , the first position adjustment mechanism 410 includes a first support platform 411 for supporting the wheels of the battery-swap vehicle 1 .

[0105] Optionally, the first supporting platform 411 is a flat platform for supporting the battery-swapping vehicle 1 .

[0106] Optionally, the first supporting platform 411 has a groove, and the wheel of the battery-swapping vehicle 1 is located in the groove.

[0107] Optionally, along the second direction, the dimension q1 of the first carrier 411 is less than or equal to the dimension q2 of the first position adjustment mechanism 410. For example, as shown in Figures 3 and 7 , along the second direction, the dimension q1 of the first carrier 411 is less than the dimension q2 of the first position adjustment mechanism 410. The dimension q1 of the first carrier 411 along the second direction and the dimension q2 of the first position adjustment mechanism 410 along the second direction may be their maximum dimensions in the second direction.

[0108] The first support platform 411 is used to support the wheels of the battery-swap vehicle 1. That is, after the battery-swap vehicle 1 enters the battery-swap platform 200, the wheels of the battery-swap vehicle 1 are located on the first support platform 411. For example, the two front wheels or the two rear wheels of the battery-swap vehicle 1 are located on the first support platform 411.

[0109] The first supporting platform 411 is movable along a first direction, so that the first supporting platform 411 can be moved along the first direction to correspond to the wheels of the battery-swapping vehicle 1. In addition, after the battery-swapping vehicle 1 travels to the first supporting platform 411, the wheels of the battery-swapping vehicle 1 can be adjusted along a second direction to adjust the position of the battery-swapping vehicle 1 on the first supporting platform 411.

[0110] In this embodiment, the wheels of the battery-swapping vehicle 1 are supported by the first supporting platform 411, thereby facilitating adjustment of the position of the battery-swapping vehicle 1 along the second direction by adjusting the position of the wheels of the battery-swapping vehicle 1 in the second direction on the first supporting platform 411.

[0111] Optionally, in some embodiments, the first load platform 411 is configured to be non-liftable. In this way, the battery-swap vehicle 1 can be lifted by the vehicle lifting device 300. For example, the chassis of the battery-swap vehicle 1 can be lifted by the vehicle lifting device 300.

[0112] In some embodiments, the first support platform 411 is configured to be liftable. Thus, after the battery swap vehicle 1 is moved to the battery swap position by the first support platform 411, the wheels can be lifted by the first support platform 411 to lift the battery swap vehicle 1, facilitating subsequent battery swap operations.

[0113] The first supporting platform 411 can lift the battery-swapping vehicle 1 along the height direction of the battery-swapping vehicle 1. The height direction of the battery-swapping vehicle 1 is perpendicular to the plane where the battery-swapping platform 200 is located.

[0114] Optionally, the liftable first load platform 411 can be used to lift the front wheels of the battery-swapping vehicle 1. For example, it can be used to lift the front wheels of some logistics vehicles. For another example, it can also be used to lift the front wheels of some passenger cars.

[0115] The battery swapping position of the battery swapping vehicle 1 may be the position of the battery swapping vehicle 1 after adjustment by the position adjustment device 400. After the battery swapping vehicle 1 is adjusted to the battery swapping position, the position of the battery swapping vehicle 1 in the x-direction and the y-direction of the battery swapping platform 200 is fixed.

[0116] Optionally, in combination with Figures 6 and 7, the first position adjustment mechanism 410 includes a lifting member 413, and the lifting member 413 is used to lift the first supporting platform 411 of the first position adjustment mechanism 410. The lifting member 413 may include a base 4131, a telescopic rod 4132, and a drive motor 4133. Among them, the base 4131 is fixedly connected to the battery exchange platform 200 or is a part of the battery exchange platform 200, and the connection between the drive motor 4133 and the telescopic rod 4132 drives the telescopic rod 4132 to extend and retract along a third direction (z direction in Figure 7), and the two ends of the telescopic rod 4132 along the third direction are respectively connected to the base 4131 and the first supporting platform 411. Driven by the drive motor 4133, the first supporting platform 411 can be lifted along the height direction of the battery exchange vehicle 1 to lift the battery exchange vehicle 1.

[0117] Optionally, the lifting height of the first supporting platform 411 can be set according to the ground clearance of the chassis of the battery-swapping vehicle 1 to reduce the situation where the battery-swapping device collides with the chassis or the battery during the battery-swapping process due to the low lifting height.

[0118] Optionally, the movable range of the first supporting platform 411 along the third direction is 250mm to 300mm, for example, 290mm. That is, through the first supporting platform 411, the wheel of the battery-swap vehicle 1 can be lifted to a height of 250mm to 300mm.

[0119] In some embodiments, as shown in combination with FIG. 5 and FIG. 7 , the first supporting platform 411 includes a wheel positioning groove 4111 .

[0120] Optionally, the wheel positioning groove 4111 is a groove on the first supporting platform 411 that is recessed along the third direction away from the battery-swap vehicle 1. Optionally, the depth of the recessed wheel positioning groove 4111 can be set according to the diameter of the wheel of the battery-swap vehicle 1.

[0121] In this way, after the battery-swapping vehicle 1 is moved to the battery-swapping position through the first supporting platform 411, the battery-swapping vehicle 1 is fixed on the first supporting platform 411 through the wheel positioning groove 4111, preventing the battery-swapping vehicle 1 from moving during the lifting process, which is beneficial to improving the reliability of the battery-swapping process.

[0122] In some embodiments, the first position adjustment mechanism 410 can move in the first direction within a range of 180 mm to 400 mm, such as 180 mm, 200 mm, 300 mm, or 400 mm.

[0123] When the movable range of the first position adjustment mechanism 410 in the first direction is less than 180 mm, the compatibility with battery-swap vehicles 1 of different lengths is poor; when the movable range of the first position adjustment mechanism 410 in the first direction is greater than 400 mm, the battery-swap station 100 occupies more space, resulting in waste of space and increased production costs.

[0124] In this embodiment, by setting the movable range of the first position adjustment mechanism 410 in the first direction to 180 mm to 400 mm, it can adapt to battery-swap vehicles 1 of various vehicle lengths and is beneficial to cost control.

[0125] Optionally, the first position adjustment mechanism 410 can be moved in the first direction within a range of 190 mm to 210 mm, for example, 190 mm, 200 mm, and 210 mm. This is beneficial for compatibility with more battery-swap vehicles 1 and is also beneficial for cost control.

[0126] Optionally, the movable range of the first position adjustment mechanism 410 in the first direction can be set according to the following information. For example, the first position adjustment mechanism 410 can be applicable to the first battery-swapping vehicle and the second battery-swapping vehicle, the first battery-swapping vehicle is the vehicle with the longest wheelbase that the first position adjustment mechanism 410 can be applied to, and the second battery-swapping vehicle is the vehicle with the shortest wheelbase that the first position adjustment mechanism 410 can be applied to, and the wheelbase is the distance between the wheel center of the front wheel and the wheel center of the rear wheel along the first direction. The minimum distance between the wheel center of the front wheel of the first battery-swapping vehicle and the battery along the first direction is d1, and the minimum distance between the wheel center of the front wheel of the second battery-swapping vehicle and the battery along the first direction is d2. The movable range of the first position adjustment mechanism 410 in the first direction is d1-d2.

[0127] In some embodiments, in combination with Figure 3, the position adjustment mechanism 400a also includes a second position adjustment mechanism 420, and the first position adjustment mechanism 410 and the second position adjustment mechanism 420 are arranged in sequence along the first direction. The first position adjustment mechanism 410 and the second position adjustment mechanism 420 are respectively used to correspond to at least two wheels of the battery-swap vehicle 1 at different positions along the first direction.

[0128] Along the first direction, the battery-swap vehicle 1 includes at least two wheels, such as front wheels and rear wheels. In the case where the battery-swap vehicle 1 includes only two pairs of wheels, namely front wheels and rear wheels, the first position adjustment mechanism 410 and the second position adjustment mechanism 420 correspond to the front wheels and the rear wheels, respectively, or the first position adjustment mechanism 410 and the second position adjustment mechanism 420 correspond to the rear wheels and the front wheels, respectively.

[0129] Optionally, the battery-swap vehicle 1 includes three or more wheels along the first direction. For example, for a medium-to-large logistics vehicle, the battery-swap vehicle 1 also includes multiple pairs of wheels located between the front and rear wheels. In this case, in addition to being respectively provided with the front and rear wheels, the first position adjustment mechanism 410 and the second position adjustment mechanism 420 can also be provided with the multiple pairs of wheels.

[0130] In this embodiment, by setting the first position adjustment mechanism 410 and the second position adjustment mechanism 420, different types of battery-swap vehicles 1 can be compatible.

[0131] In some embodiments, the first position adjustment mechanism 410 is used to be set corresponding to the front wheel position of the battery-swap vehicle 1, and the second position adjustment mechanism 420 is used to be set corresponding to the rear wheel position of the battery-swap vehicle 1.

[0132] Optionally, the battery position in the battery-swap vehicle 1 is positioned with the front wheel as a reference, and along the first direction, the size of the first position adjustment mechanism 410 is smaller than the size of the second position adjustment mechanism 420. By setting the first position adjustment mechanism 410 corresponding to the front wheel position of the battery-swap vehicle 1 to be movable along the first direction, the parking and positioning of the battery-swap vehicle 1 are facilitated, and the production cost is also reduced.

[0133] FIG8 is a schematic diagram of a second position adjustment mechanism according to an embodiment of the present application. In some embodiments, as shown in FIG3 and FIG8 , the second position adjustment mechanism 420 is fixed in position along the first direction. The second position adjustment mechanism 420 includes a second support 421. The dimension k2 of the second support 421 along the first direction is greater than the dimension k1 of the first support 411 of the first position adjustment mechanism 410 along the first direction.

[0134] The dimension k2 of the second carrying platform 421 along the first direction may be the maximum dimension of the second carrying platform 421 along the first direction, and the dimension k1 of the first carrying platform 411 along the first direction may be the maximum dimension of the first carrying platform 411 along the first direction.

[0135] The first position adjustment mechanism 410 includes a first load-bearing platform 411, and the second position adjustment mechanism 420 includes a second load-bearing platform 421. After the first position adjustment mechanism 410 is moved to the destination position, the battery-swap vehicle 1 can be parked on the first load-bearing platform 411 and the second load-bearing platform 421. The battery-swap vehicle 1 is supported by the first load-bearing platform 411 and the second load-bearing platform 421 and the position of the battery-swap vehicle 1 in the second direction is adjusted on the first load-bearing platform 411 and the second load-bearing platform 421.

[0136] The first position adjustment mechanism 410 is movable along the first direction, the second position adjustment mechanism 420 is fixed along the first direction, and the maximum dimension of the second support platform 421 along the first direction is larger than the maximum dimension of the first support platform 411 along the first direction. In this way, the structural complexity of the position adjustment device 400 can be reduced while being compatible with various types of battery-swap vehicles, which is conducive to reducing production costs.

[0137] Optionally, the second carrying platform 421 is configured to be liftable. The lifting structure of the second carrying platform 421 may be the same as the structure of the lifting member 413 of the first carrying platform 411, and will not be described in detail herein.

[0138] Optionally, the second supporting platform 421 can be lifted in a range of 150 mm to 200 mm, for example, 150 mm, 170 mm, 190 mm, and 200 mm.

[0139] In some embodiments, the second supporting platform 421 is used to support at least two wheels of the battery-swapping vehicle 1 along the first direction.

[0140] In the case where the battery-swap vehicle 1 has three or more pairs of wheels, the second support platform 421 can support at least two wheels in the first direction of the battery-swap vehicle 1. In this way, through the provision of the second support platform 421, the position adjustment device 400 can be compatible with more types of battery-swap vehicles 1, such as non-passenger vehicles including three or more pairs of wheels.

[0141] In some embodiments, along the first direction, the dimension k2 of the second carrying platform 421 is 1000 mm to 1500 mm; alternatively, k2 is 1100 mm to 1300 mm. For example, the dimension k2 of the second carrying platform 421 along the first direction is 1000 mm, 1100 mm, 1200 mm, 1300 mm, or 1500 mm.

[0142] Optionally, the size of the second position adjustment mechanism 420 along the first direction is the same as the size k2 of the second carrier 421 along the first direction. Optionally, the size of the first position adjustment mechanism 410 along the first direction is the same as the size k1 of the first carrier 411 along the first direction.

[0143] In this embodiment, the size of the second position adjustment mechanism 420 is 1000mm to 1500mm, and the wheels of various types of battery-swap vehicles can be located on the second position adjustment mechanism 420. For example, after a vehicle length of more than 4m, 6m, or even 8m is driven to the battery-swap platform, the rear wheels can be completely located on the second position adjustment mechanism 420. In addition, by moving the second position adjustment mechanism 420 a small distance in the first direction or not moving it at all, the position of battery-swap vehicles 1 of different lengths can be adjusted.

[0144] In some embodiments, the second position adjustment mechanism 420 is movable along a first direction.

[0145] In this embodiment, the first position adjustment mechanism 410 and the second position adjustment mechanism 420 are both movable along the first direction. This is conducive to further increasing the adjustment range of the position adjustment mechanism 400a in the first direction, and can be applicable to more types of battery-swap vehicles 1; at the same time, the flexibility of the position adjustment mechanism 400a is increased, which facilitates the flexible adjustment of the positions of the first position adjustment mechanism 410 and the second position adjustment mechanism 420 in the first direction according to actual conditions.

[0146] Optionally, the moving assembly 500 is connected to the second position adjustment mechanism 420 and is used to move the second position adjustment mechanism 420 to a target position along the first direction.

[0147] The target position of the second position adjustment mechanism 420 can be the position of the second position adjustment mechanism 420 obtained by the control system of the battery swap station 100 based on the vehicle information of the battery swap vehicle 1. When the second position adjustment mechanism 420 is at the target position, the battery swap vehicle 1 or the wheels of the battery swap vehicle 1 are located on the second position adjustment mechanism 420.

[0148] In some embodiments, the movable range of the first position adjustment mechanism 410 is greater than the movable range of the second position adjustment mechanism 420. In this way, the first position adjustment mechanism 410 has a larger movable range in the first direction, and the second position adjustment mechanism 420 has a smaller movable range in the second direction, which can reduce production costs while ensuring adaptability to more types of battery-swap vehicles 1.

[0149] In some embodiments, in combination with Figures 7 and 8, the position adjustment device 400 also includes a position calibration mechanism 460, which is used to move the battery-swap vehicle 1 to a preset position along a second direction, where the second direction is perpendicular to the first direction.

[0150] After the battery swap vehicle 1 enters the battery swap platform 200, the battery swap vehicle 1 may deviate from the preset position. The position calibration mechanism 460 can move the battery swap vehicle 1 along the second direction to the preset position, thereby facilitating subsequent battery swap operations.

[0151] The preset position is the position where the battery-swapping vehicle 1 performs battery swapping, that is, the battery swapping position.

[0152] In some embodiments, the position calibration mechanism 460 includes a push rod mechanism 461, which is used to push the battery-swap vehicle 1 to a preset position along the second direction.

[0153] After the battery swapping vehicle 1 enters the battery swapping platform, the battery swapping vehicle 1 may be tilted or tilted toward one side of the second direction of the battery swapping platform 200. The push rod mechanism 461 can be used to straighten the body of the battery swapping vehicle 1 or move the battery swapping vehicle 1 to a preset position along the second direction, thereby facilitating subsequent battery swapping operations.

[0154] In some embodiments, the first position adjustment mechanism 410 includes a first supporting platform 411, and the position adjustment device 400 also includes a second supporting platform 421. The first supporting platform 411 and the second supporting platform 421 are respectively used to support the wheels of the battery-swap vehicle 1 at different positions along the first direction. At least one of the first supporting platform 411 and the second supporting platform 421 is provided with multiple rollers 462 arranged along the second direction.

[0155] The multiple rollers 462 are arranged along the second direction, so that under the action of the push rod mechanism 461, the multiple rollers 462 can transport the battery-swap vehicle 1 to a preset position along the second direction.

[0156] In some embodiments, the push rod mechanism 461 is disposed on at least one of the first supporting platform 411 and the second supporting platform 421 to push the battery-swap vehicle 1 to a preset position on the first supporting platform 411 and / or the second supporting platform 421.

[0157] Optionally, as shown in Figures 7 and 8, the push rod mechanism 461 includes a push rod 4611 and a push rod driving member (not shown in the figures), the push rod 4611 and the push rod driving member are connected, and the push rod 4611 is a rod extending in a first direction. Driven by the push rod driving member, the push rod 4611 moves in a second direction, thereby pushing the battery-swap vehicle 1 to move in the second direction.

[0158] Optionally, after the push rod 4611 pushes the battery swap vehicle 1 to a preset position, the push rod 4611 returns to its initial position. Optionally, the initial position of the push rod 4611 is located at the first end of the first support platform 411 and / or the second support platform 421 along the second direction, which is the end close to the edge of the battery swap platform 200.

[0159] Optionally, the movable range of the push rod 4611 along the second direction is 300 mm to 500 mm, for example, 300 mm, 400 mm, 500 mm.

[0160] Optionally, the movable range of the wheels of the battery-swapping vehicle 1 along the second direction is 200mm to 400mm, for example, 200mm, 350mm, 400mm.

[0161] In this embodiment, the push rod mechanism 461 is arranged on at least one of the first load-bearing platform 411 and the second load-bearing platform 421. On the one hand, it is convenient to push the battery-swapping vehicle 1; on the other hand, there is no need to set up additional installation space for the push rod mechanism 461 on the battery-swapping platform 200, which is conducive to improving the space utilization of the battery-swapping platform 200.

[0162] In some embodiments, as shown in FIG7 , at least one of the first support platform 411 and the second support platform 421 is provided with two rows of rollers 462 facing each other along a first direction. The two rows of rollers 462 are arranged at an angle to each other to form positioning grooves for fixing the wheels. In this way, after the battery-swapping vehicle 1 moves to a preset position, the positioning grooves formed by the rollers 462 can be used to position and fix the battery-swapping vehicle.

[0163] Each column of rollers 462 includes a plurality of rollers 462 arranged along the second direction.

[0164] The two rows of rollers 462 are arranged to be inclined with respect to each other, that is, there is a certain angle between the two rows of rollers 462, thereby jointly defining a positioning groove for fixing the wheel.

[0165] Figure 9 is a schematic diagram of the first position adjustment mechanism according to an embodiment of the present application, and Figure 10 is a schematic cross-sectional diagram along the BB direction of Figure 9. Optionally, as shown in Figures 9 and 10, the angle between the two rows of rollers 462 is an obtuse angle, for example, the angle α between the two rows of rollers 462 is 148°.

[0166] Optionally, the distance m1 between the two rows of rollers 462 along the first direction is 80 mm to 90 mm, for example, 80 mm, 85 mm, or 90 mm.

[0167] Optionally, the diameter p1 of one roller 462 is 60 mm.

[0168] Optionally, the second supporting platform 421 includes two second sub-supporting platforms that are opposite to each other and spaced apart along the second direction. The minimum distance D between two adjacent second sub-supporting platforms is min It can be 250mm~300mm, such as 250mm, 290mm, 300mm; the maximum distance D max It can be 2000mm to 2300mm, for example, 2000mm, 2170mm, 2300mm.

[0169] Optionally, as shown in Figures 7, 8, and 10, the two rows of rollers 462 on the first platform 411 are tilted to form positioning grooves for fixing wheels, and the two rows of rollers 462 on the second platform 421 are horizontally arranged. In this way, it is convenient for the battery-swap vehicle to be parked on the first platform 411 and the second platform 421.

[0170] In some embodiments, the dimension q1 of the first support platform 411 along the second direction and / or the dimension q3 of the second support platform 421 along the second direction is 2000 mm to 2300 mm, optionally 2170 mm. This makes it easier to adapt to battery-swap vehicles 1 of different widths and wheel sizes.

[0171] In some embodiments, the position adjustment mechanism 400a also includes a third position adjustment mechanism.

The adjustment mechanism 490 can be used to move the battery-swapping vehicle 1 to the preset position, thereby facilitating subsequent battery-swapping operations.

[0180] Optionally, the structure of the adjustment mechanism 490 is the same as the structure of the position calibration mechanism 460 described above, and similar descriptions can be found above and in related drawings.

[0181] For example, the adjustment mechanism includes a push rod mechanism, which is used to push the battery swap vehicle 1 to a preset position along the second direction. After the battery swap vehicle 1 enters the battery swap platform 200, the battery swap vehicle 1 may have a body that is skewed or biased toward one side of the second direction of the battery swap platform 200. Through the push rod mechanism, the body of the battery swap vehicle 1 can be straightened, or the battery swap vehicle 1 can be moved to a preset position along the second direction, thereby facilitating subsequent battery swap operations.

[0182] Optionally, at least one of the at least three position adjustment mechanisms includes a supporting platform, which is used to support the wheels of the battery-swap vehicle 1. The structure of the supporting platform is the same as that of the first supporting platform or the second supporting platform mentioned above, and similar descriptions can be found above and in related drawings.

[0183] For example, a plurality of rollers arranged along the second direction are provided on the supporting platform, and the plurality of rollers are used to transport the battery-swap vehicle 1 along the second direction.

[0184] For another example, two rows of rollers are arranged on the support platform in a first direction and are arranged to be tilted relative to each other to form positioning grooves for fixing the wheels. In this way, after the battery-swapping vehicle 1 moves to a preset position, the positioning grooves formed by the rollers can be used to position and fix the battery-swapping vehicle.

[0185] For another example, the carrying platform is configured to be liftable.

[0186] The present application provides a battery swap station, comprising the position adjustment device 400 in any one of the embodiments described above.

[0187] Figure 12 is a schematic diagram of a battery replacement method according to an embodiment of the present application. As shown in Figure 12, the present application provides a battery replacement method 500, comprising the following steps.

[0195] The position adjustment device 400 includes a plurality of position adjustment mechanisms 400a that can adjust their positions along a first direction. In step 520, the positions of the plurality of position adjustment mechanisms 400a in the first direction can be adjusted to correspond to the information of the battery-swap vehicle 1 based on the information of the battery-swap vehicle 1. In this way, after the battery-swap vehicle 1 enters the battery-swap platform, the battery-swap vehicle 1 can be positioned on the corresponding position adjustment mechanism 400a.

[0196] For example, step 520 can be applied to a position adjustment device 400 including a first position adjustment mechanism 410. After obtaining the information of the battery-swapping vehicle 1, the first position adjustment mechanism 410 can be controlled to move to the destination position along the first direction according to the information of the battery-swapping vehicle 1. In this way, after the battery-swapping vehicle 1 enters the battery-swapping platform 200, the wheels of the battery-swapping vehicle 1 can be located on the first position adjustment mechanism 410, and then the position of the battery-swapping vehicle 1 can be adjusted by the first position adjustment mechanism 410.

[0197] The position adjustment device 400 includes a plurality of position adjustment mechanisms 400a fixed along a first direction. In step 520, the position adjustment mechanism 400a corresponding to the battery swapping vehicle 1 can be determined based on the information of the battery swapping vehicle 1. In this way, after the battery swapping vehicle 1 enters the battery swapping platform, it can be positioned on the corresponding position adjustment mechanism 400a.

[0198] For example, step 520 can be applied to a position adjustment device 400 including a fourth position adjustment mechanism 440, a fifth position adjustment mechanism 450, and a sixth position adjustment mechanism 460 that are sequentially arranged and fixed along a first direction. The sixth position adjustment mechanism 460 corresponds to the rear wheel of the battery-swap vehicle 1, the fourth position adjustment mechanism 440 corresponds to the front wheel of the battery-swap vehicle 1, and the fifth position adjustment mechanism 450 corresponds to the wheel between the front wheel and the rear wheel of the battery-swap vehicle 1.

[0199] In this embodiment, it is convenient to adjust the position adjustment device 400 to be compatible with different types of battery-swapping vehicles 1 according to the specific settings of the position adjustment device 400 and the information of the battery-swapping vehicle 1.

[0200] In some embodiments, the method 500 also includes: after the battery-swap vehicle 1 is parked on the position adjustment device 400 , controlling the position adjustment device 400 to adjust the position of the battery-swap vehicle 1 .

[0201] In this way, after the battery-swapping vehicle enters the battery-swapping platform 200, the corresponding position adjustment mechanism 400a in the position adjustment device 400 is controlled to adjust the position of the battery-swapping vehicle 1 in the second direction to facilitate subsequent battery-swapping operations.

[0202] It should be noted that the relevant technical solutions of the position adjustment device 400 not mentioned in the battery replacement method can refer to the technical solutions of the reference position adjustment device embodiment, and will not be elaborated here.

[0203] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application.
