Description

Technical Field

[0001] 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

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. In this case, electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages of energy conservation and environmental protection. For electric vehicles, battery replacement is an important way to supplement electric energy, which can quickly replenish energy for electric vehicles that are insufficient in energy.

[0003] Before replacing the battery of a vehicle, it is necessary to park the vehicle on the battery swap platform and adjust and position the vehicle through the position adjustment device on the battery swap platform. However, the existing position adjustment device can only adjust a single vehicle model and it is difficult to achieve compatibility with multiple vehicle models. Therefore, how to provide a position adjustment device to be compatible with different vehicle models is a technical problem that needs to be solved urgently. Summary of the invention

[0004] 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.

[0005] 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 a vehicle length direction and a vehicle width direction.

[0006] The embodiment of the present application provides a position adjustment device, which includes at least one position adjustment mechanism. Through the movement of 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 replacement posture or position of different types of battery swapping vehicles to facilitate subsequent battery replacement operations. Therefore, the technical solution of the present application can be compatible with different vehicle models, which is conducive to the development and promotion of battery swapping stations.

[0007] In a possible implementation, the position adjustment mechanism includes a first position adjustment mechanism, and the first position adjustment mechanism 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 wheel of the battery swapping vehicle is located on the first position adjustment mechanism, thereby facilitating the first position adjustment mechanism to adjust the battery swapping position of the battery swapping vehicle.

[0008] In a possible implementation, the position adjustment mechanism further includes a moving component, 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 setting the moving component, the first position adjustment mechanism can be moved in the first direction, thereby achieving compatibility of the first position adjustment mechanism with battery-swap vehicles of different vehicle lengths.

[0009] In a possible implementation, the moving assembly includes a driving member and a connecting member, one end of the connecting member is connected to the driving member, and the other end is 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, so as to drive the first position adjustment mechanism to move along the first direction.

[0010] In a possible implementation, the first position adjustment mechanism includes a first bearing platform, and the first bearing platform is used to bear the wheel of the battery-swapping vehicle. In this way, the first bearing platform is movable along a first direction, so that the first bearing platform can be moved along the first direction to correspond to the wheel of the battery-swapping vehicle.

[0011] In a possible implementation, the first load platform is configured to be liftable. Thus, after the battery swapping vehicle is moved to the battery swapping position by the first load platform, the wheels can be lifted by the first load platform to lift the battery swapping vehicle, facilitating subsequent battery swapping operations.

[0012] In a possible implementation, the first support platform includes a wheel positioning groove. Thus, after the battery swapping vehicle is moved to the battery swapping position by the first support platform, the wheel positioning groove is used to fix the battery swapping vehicle on the first support platform, thereby preventing the battery swapping vehicle from moving during the lifting process, which is beneficial to improving the reliability of the battery swapping process.

[0013] In a possible implementation, the movable range of the first position adjustment mechanism in the first direction is 180 mm to 400 mm, so that it is easy to adapt to battery-swap vehicles of different lengths. Optionally, the movable range of the first position adjustment mechanism in the first direction is 190 mm to 210 mm, so that it is easy to adapt to battery-swap vehicles of different lengths while reducing the increase in cost caused by the large movable range of the first position adjustment mechanism in the first direction, which is conducive to cost control.

[0014] In one possible implementation, the position adjustment mechanism also 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.

[0015] In a 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.

[0016] In the above scheme, when the battery position in the battery swapping vehicle is positioned based on the front wheel, by adjusting the position of the first position adjustment mechanism in the first direction, it is convenient to park the front wheel of the vehicle at a predetermined position, thereby facilitating battery swapping of the battery swapping vehicle at a 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, setting the first position adjustment mechanism to be movable along the first direction is conducive to reducing production costs.

[0017] In a possible implementation, the position of the second position adjustment mechanism along the first direction is fixed, 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.

[0018] 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 is moved to the target position, the battery-swap vehicle can be parked on the first load-bearing platform and the second load-bearing platform, and the battery-swap vehicle is carried 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.

[0019] In one possible implementation, the second load-bearing platform is used to carry 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 load-bearing platform can carry at least two wheels of the battery-swapping vehicle in the first direction. In this way, through the setting of the second load-bearing 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.

[0020] In a possible implementation, along the first direction, the size of the second load platform is 1000 mm to 1500 mm; optionally, along the first direction, the size of the second load platform is 1100 mm to 1300 mm. In this way, the position adjustment device is compatible with more battery-swap vehicles of different lengths.

[0021] In a possible implementation, the second position adjustment mechanism is movable along the first direction. Both the first position adjustment mechanism and the second position adjustment mechanism are movable along the first direction, which is conducive to further increasing the adjustment range of the position of the position adjustment device in the first direction and can be applied to more types of battery-swap vehicles; at the same time, the flexibility of the position adjustment device is increased, which is convenient for flexibly adjusting the positions of the first position adjustment mechanism and the second position adjustment mechanism in the first direction according to actual conditions.

[0022] In a possible implementation, the movable range of the first position adjustment mechanism is greater than the movable range of the second position adjustment mechanism. In this way, the first position adjustment mechanism has a larger movable range in the first direction, and the second position adjustment mechanism has a smaller movable range in the second direction, which can reduce production costs while ensuring compatibility with more types of battery-swap vehicles.

[0023] In a possible implementation, the position adjustment device further includes a position calibration mechanism, and the position calibration mechanism is configured to move the battery swap vehicle to a preset position along the second direction. After the battery swap vehicle enters the battery swap platform, the battery swap vehicle may deviate from the preset position, and the position calibration mechanism can be used to move the battery swap vehicle to the preset position, thereby facilitating subsequent battery swap operations.

[0024] In a possible implementation, the position calibration mechanism includes a push rod mechanism, and the push rod mechanism 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 the body may be biased toward one side of the second direction of the battery swap platform. Through the push rod mechanism, the body of the battery swap vehicle can be straightened, or the battery swap vehicle can be moved to the preset position along the second direction, thereby facilitating subsequent battery swap operations.

[0025] In a possible implementation, the first position adjustment mechanism includes a first load-bearing platform, and the position adjustment device also includes a second load-bearing platform. The first load-bearing platform and the second load-bearing platform are respectively used to support the wheels of the battery-swap vehicle at different positions along the first direction, and at least one of the first load-bearing platform and the second load-bearing platform is provided with a plurality of rollers arranged along the second direction.

[0026] In the above scheme, the plurality of rollers are arranged along the second direction, so that under the action of the push rod mechanism, the plurality of rollers can transport the battery-swap vehicle to a preset position along the second direction.

[0027] In a possible implementation, the push rod mechanism is provided on at least one of the first load platform and the second load platform, so as to push the battery swap vehicle to the preset position on the first load platform and / or the second load platform. In this way, on the one hand, it is convenient to push the battery swap vehicle; on the other hand, there is no need to set up additional installation space for the push rod mechanism on the battery swap platform, which is conducive to improving the space utilization rate of the battery swap platform.

[0028] In a possible implementation, at least one of the first load platform and the second load platform is provided with two rows of rollers opposite to each other along the first direction, and the two rows of rollers are arranged to be inclined with respect to each other to form positioning grooves for fixing wheels. In this way, after the battery-swapping vehicle moves to a preset position, the positioning grooves formed by the rollers can be used to position and fix the battery-swapping vehicle.

[0029] In a possible implementation, the size of the first load platform along the second direction and / or the size of the second load platform along the second direction is 2000mm-2300mm; optionally, the size of the first load platform along the second direction and / or the size of the second load platform along the second direction is 2000mm-2200mm. In this way, it is easy to adapt to battery-swap vehicles with different vehicle widths and different wheel sizes.

[0030] In a possible implementation, the position adjustment device includes at least three position adjustment mechanisms, which are arranged in sequence 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 a corresponding position adjustment mechanism to adjust the battery swapping position of the battery swapping vehicle according to the length of the battery swapping vehicle.

[0031] In a possible implementation, the position adjustment device further includes an adjustment mechanism, and the adjustment mechanism is used to move the battery swap vehicle to a preset position along the second direction, and the second direction is perpendicular to the first direction. After the battery swap vehicle enters the battery swap platform, the battery swap vehicle may deviate from the preset position, and the battery swap vehicle can be moved to the preset position by the adjustment mechanism, thereby facilitating subsequent battery swap operations.

[0032] 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.

[0033] In a 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.

[0034] The above scheme can be applicable 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.

[0035] In a possible implementation, before the battery swapping vehicle enters the battery swapping platform, adjusting the position adjustment device according to the information of the battery swapping vehicle includes: moving the positions of several position adjustment mechanisms to correspond to the information of the battery swapping vehicle; or determining several position adjustment mechanisms corresponding to the information of the battery swapping vehicle. In this way, it is convenient to adjust the battery swapping positions of different types of battery swapping vehicles according to the specific settings of the position adjustment device and the information of the battery swapping vehicle.

[0036] In a 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.

[0037] The present application provides a position adjustment device, which includes at least one position adjustment mechanism. Through the movement of 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 replacement posture or position of different types of battery swapping vehicles to facilitate subsequent battery replacement operations. Therefore, the technical solution of the present application can be compatible with different vehicle models, which is conducive to the development and promotion of battery swapping stations.

DETAILED DESCRIPTION

[0054] The following detailed description and drawings of the embodiments of the present application are used to illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0055] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating the orientation or positional relationship are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship. "Vertical" is not strictly vertical, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0056] 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.

[0057] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those 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.

[0058] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0059] With the increase in the number of electric vehicles, the requirements for electric vehicles are getting higher and higher. During the driving process of electric vehicles, the power will gradually decrease. In the current technology, it is necessary to regularly charge the battery in the vehicle through the 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 car, which will seriously affect the user's car experience. Therefore, battery swap stations came into being, which 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 the battery charging time, will not affect the user's use of the car, and greatly improve the user's experience of the vehicle.

[0060] Before replacing the battery of a vehicle, it is necessary to park the vehicle on the battery swap platform and adjust and position the vehicle through the position adjustment device on the battery swap platform. However, some position adjustment devices can only adjust a single vehicle model and are difficult to achieve compatibility with multiple vehicle models, which is not conducive to the development and promotion of battery swap stations.

[0061] In view of this, the present application provides a position adjustment device for vehicle battery replacement, the position adjustment device includes at least one position adjustment mechanism, the position adjustment mechanism is movable along at least one of a first direction or a second direction, the first direction and the second direction are the vehicle length direction and the vehicle width direction respectively. The moved position adjustment mechanism can correspond to the position of the battery replacement vehicle after entering the battery replacement station, so as to facilitate the subsequent position adjustment of the battery replacement vehicle. In this way, the position adjustment device can be compatible with different types of battery replacement vehicles, which is conducive to the development and promotion of battery replacement stations.

[0062] Figure 1 It is a structural schematic diagram of a battery swap station 100 provided in one embodiment of the present application.

[0063] The battery swap station 100 may include a battery rack 101. The battery rack 101 may be configured with a plurality of batteries. The battery rack 101 may include a battery charging compartment and a battery cache device. The battery may be stored in the battery charging compartment so that the battery may be charged. The battery cache device may be used to temporarily store a depleted battery replaced from a vehicle.

[0064] In addition to the battery rack 101, the battery swap station 100 may also include a palletizer 102 and a mobile battery swap device ( Figure 1 (not shown). The mobile battery exchange 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 charges the depleted batteries. In addition, the palletizer 102 can also transport the fully charged batteries on the battery rack 101 to the mobile battery exchange device, and the mobile battery exchange device carries the fully charged batteries to the vehicle and installs the fully charged batteries on the vehicle. As an example, the mobile battery exchange device can be, for example, a rail guided vehicle (RGV) or an automated guided vehicle (AGV).

[0065] The battery swap station 100 may further include a battery swap platform 200 . Figure 2 A schematic diagram of a battery swap vehicle 1 traveling on a battery swap platform 200 is shown. On the battery swap platform 200, a mobile battery swap device can replace the battery on the battery swap vehicle 1. Figure 1 and Figure 2 The x direction 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 move along the y direction to the vicinity of the battery swap vehicle 1 through the guide rails on the battery swap platform 200.

[0066] 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 .

[0067] 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 be lifted first, 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.

[0068] As an example, in Figure 1 and Figure 2In the embodiment shown, 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. Figure 2 As shown. Along the travel 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.

[0069] When the battery swap vehicle 1 is lifted, the mobile battery swap device can be moved to the bottom of the battery swap vehicle 1. When 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 fully charged batteries 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.

[0070] 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. In 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.

[0071] After the battery swapping vehicle 1 completes the battery swapping, 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 .

[0072] Figure 3 Schematic diagram of a battery swap platform according to an embodiment of the present application. Figure 3 As shown, the battery swap platform 200 includes a position adjustment device 400 .

[0073] Combination Figure 3 As shown, 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, and the first direction and the second direction can be the vehicle length direction and the vehicle width direction, respectively. The position adjustment device 400 can adjust the position to correspond to carrying different types of battery replacement vehicles 1, and the different types of battery replacement vehicles 1 can be different in at least one of the vehicle length and vehicle width dimensions, and are used for subsequent vehicle position adjustment.

[0074] The position of the position adjustment mechanism 400a can be adjusted, for example, the position of the position adjustment mechanism 400a is adjustable along the first direction, but not adjustable along the 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 adjustable along the first direction.

[0075] The first direction is different from the second direction, for example, the first direction may be perpendicular to the second direction.

[0076] 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, and the position of the battery swapping vehicle 1 can be adjusted, positioned and fixed through the position adjustment mechanism 400a.

[0077] Different types of battery swapping vehicles 1 differ in at least one of vehicle length and vehicle width. For example, different types of battery swapping vehicles 1 may include passenger vehicles and logistics vehicles, and passenger vehicles and logistics vehicles have different vehicle lengths and vehicle widths. For another example, logistics vehicles include multiple different types of logistics vehicles, and due to their different uses or designs, different logistics vehicles have different vehicle lengths, vehicle widths, number of wheels, etc.

[0078] 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.

[0079] 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.

[0080] 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 swapping vehicles 1, and the different types of battery swapping vehicles 1 are different in at least one of the vehicle length and vehicle width. In this way, when different types of battery swapping vehicles 1 need to be replaced, the position adjustment device 400 can be compatible with and carry different types of battery swapping vehicles 1, so that the battery replacement position of different types of battery swapping vehicles 1 can be adjusted to facilitate subsequent battery replacement 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 swapping stations.

[0081] In some embodiments, the position adjustment mechanism 400 a includes a first position adjustment mechanism 410 , which is movable along a first direction.

[0082] The first direction is the length direction of the battery swapping vehicle 1, or may be the driving direction of the battery swapping vehicle 1. Figures 1 to 3 As shown, the first direction may be the x direction in the figure.

[0083] Because different types of battery swapping vehicles 1 have different lengths or widths, after the battery swapping vehicle 1 enters the battery swapping platform 200, the position of the battery swapping vehicle 1 on the battery swapping platform 200 is different, and the position of the corresponding position adjustment mechanism 400a is also different. Figures 1 to 3 As shown, after entering the battery swap platform 200, the front wheels of the battery swap vehicle 1 with a longer vehicle length are closer to the front ramp 104 relative to the front wheels of the battery swap vehicle 1 with a shorter vehicle length, and / or the rear wheels of the battery swap vehicle 1 with a longer vehicle length are closer to the rear ramp 104 relative to the rear wheels of the battery swap vehicle 1 with a shorter vehicle length.

[0084] 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 swapping vehicles 1, so that the battery swapping vehicle 1 or the wheels of the battery swapping vehicle 1 can be located on the first position adjustment mechanism 410, thereby facilitating the first position adjustment mechanism 410 to adjust the battery swapping position of the battery swapping vehicle 1.

[0085] Figure 4 Schematic diagram of a position adjustment device according to an embodiment of the present application. Figure 4 As shown, the position adjustment mechanism 400a includes a moving assembly 500, which is connected to the first position adjustment mechanism 410 and is used to move the first position adjustment mechanism 410 to a target position along a first direction.

[0086] Alternatively, if Figure 4As shown, the moving assembly 500 is located at the end of the first position adjustment mechanism 410 along the first direction. In this way, it is convenient to install the moving assembly 500 and to connect the moving assembly 500 with the first position adjustment mechanism 410 so that the first position adjustment mechanism 410 moves along the first direction.

[0087] 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.

[0088] 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 the battery swap vehicle 1 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 the battery swap vehicle 1 enters the battery swap platform 200.

[0089] By setting the moving component 500, the first position adjustment mechanism 410 can be moved in the first direction, so that the first position adjustment mechanism 410 can be compatible with battery-swap vehicles 1 of different vehicle lengths.

[0090] Figure 5 for Figure 4 An enlarged schematic diagram of area A in FIG. Figure 6 FIG. 4 is a schematic diagram of another perspective of a position adjustment device 400 according to an embodiment of the present application. Figure 5 and Figure 6 As shown, 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 as to drive the first position adjustment mechanism 410 to move along the first direction under the drive of the driving member 510.

[0091] Optionally, the connecting member 520 extends along the first direction, and 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 .

[0092] 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 through the spiral transmission member, and the other end is connected to the first position adjustment mechanism 410. When the driving member 510 rotates, the spiral transmission member can be driven to rotate, 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.

[0093] The driving member 510 may be a motor, which provides a power source for the movement of the first position adjustment mechanism 410 .

[0094] 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.

[0095] 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 .

[0096] 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.

[0097] The guide rail can be arranged on the battery exchange platform 200 and extend along the first direction, so that the first position adjustment mechanism 410 can move along the guide rail. By setting the guide rail, the risk of the first position adjustment mechanism 410 being offset during movement can be reduced, which is conducive to improving the accuracy of the position of the first position adjustment mechanism 410 and reducing the risk of the first position adjustment mechanism 410 being offset in the second direction during movement.

[0098] 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, and 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.

[0099] Optionally, the first locking portion may be a groove provided on the wall of the guide rail facing the first position adjustment mechanism 410, and the second locking portion may 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 in 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 fixing the first position adjustment mechanism 410 on the guide rail.

[0100] Optionally, a sensor is disposed on the first position adjustment mechanism 410 to detect the current position of the first position adjustment mechanism 410 .

[0101] Figure 7 Schematic diagram of a position adjustment device according to an embodiment of the present application. Figure 5 and Figure 7As shown, the first position adjustment mechanism 410 includes a first supporting platform 411, and the first supporting platform 411 is used to support the wheels of the battery-swap vehicle 1.

[0102] Optionally, the first supporting platform 411 is a flat platform for supporting the battery-swap vehicle 1 .

[0103] Optionally, the first supporting platform 411 has a groove, and the wheel of the battery-swap vehicle 1 is located in the groove.

[0104] 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. Figure 3 and Figure 7 As shown, along the second direction, the dimension q1 of the first carrier 411 is smaller 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 the maximum dimension in the second direction.

[0105] 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.

[0106] The first support platform 411 is movable along the first direction, so that the first support 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 support platform 411, the wheels of the battery-swapping vehicle 1 can be adjusted along the second direction to adjust the position of the battery-swapping vehicle 1 on the first support platform 411.

[0107] In this embodiment, the wheels of the battery swap vehicle 1 are supported by the first supporting platform 411, so that the position of the battery swap vehicle 1 along the second direction can be adjusted by adjusting the position of the wheels of the battery swap vehicle 1 in the second direction on the first supporting platform 411.

[0108] 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 is lifted by the vehicle lifting device 300.

[0109] In some embodiments, the first load platform 411 is configured to be liftable. Thus, after the battery swapping vehicle 1 is moved to the battery swapping position by the first load platform 411, the wheels can be lifted by the first load platform 411 to lift the battery swapping vehicle 1, so as to facilitate subsequent battery swapping operations.

[0110] The first support 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.

[0111] Optionally, the first liftable 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.

[0112] 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.

[0113] Optionally, combined Figure 6 and Figure 7 As shown, the first position adjustment mechanism 410 includes a lifting member 413, and the lifting member 413 is used to lift the first support 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. The base 4131 is fixedly connected to the battery exchange platform 200 or is a part of the battery exchange platform 200, and the drive motor 4133 is connected to the telescopic rod 4132 to drive the telescopic rod 4132 along the third direction ( Figure 7 The two ends of the telescopic rod 4132 along the third direction are respectively connected to the base 4131 and the first support platform 411. Driven by the drive motor 4133, the first support platform 411 can be lifted along the height direction of the battery swap vehicle 1 to lift the battery swap vehicle 1.

[0114] Optionally, the lifting height of the first support 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.

[0115] Optionally, the movable range of the first support platform 411 along the third direction is 250 mm to 300 mm, for example, 290 mm. That is, through the first support platform 411, the wheel of the battery-swap vehicle 1 can be lifted to a height of 250 mm to 300 mm.

[0116] In some embodiments, in combination Figure 5 and Figure 7 As shown, the first supporting platform 411 includes a wheel positioning groove 4111 .

[0117] Optionally, the wheel positioning groove 4111 is a groove on the first support 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.

[0118] In this way, after the battery swap vehicle 1 is moved to the battery swap position through the first supporting platform 411, the battery swap vehicle 1 is fixed on the first supporting platform 411 through the wheel positioning groove 4111 to prevent the battery swap vehicle 1 from moving during the lifting process, which is beneficial to improving the reliability of the battery swap process.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] Optionally, the first position adjustment mechanism 410 can be moved in the first direction within a range of 190 mm to 210 mm, such as 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.

[0123] 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-exchange vehicle and the second battery-exchange vehicle, the first battery-exchange vehicle is the vehicle with the longest wheelbase that the first position adjustment mechanism 410 can be applied to, and the second battery-exchange 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-exchange 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-exchange 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.

[0124] In some embodiments, in combination Figure 3As shown, the position adjustment mechanism 400a also includes a second position adjustment mechanism 420. 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.

[0125] 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.

[0126] Optionally, along the first direction, the battery-swap vehicle 1 includes three or more wheels. For example, for a medium or large logistics vehicle, the battery-swap vehicle 1 also includes multiple pairs of wheels located between the front wheels and the rear wheels. In this case, in addition to being respectively arranged corresponding to the front wheels and the rear wheels, the first position adjustment mechanism 410 and the second position adjustment mechanism 420 can also be arranged corresponding to the multiple pairs of wheels.

[0127] In this embodiment, by providing the first position adjustment mechanism 410 and the second position adjustment mechanism 420 , different types of battery-swap vehicles 1 can be compatible.

[0128] 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 .

[0129] 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 is facilitated, and the production cost is also reduced.

[0130] Figure 8 Schematic diagram of a second position adjustment mechanism according to an embodiment of the present application. Figure 3 and Figure 8 As shown, the position of the second position adjustment mechanism 420 along the first direction is fixed, and the second position adjustment mechanism 420 includes a second carrier 421 , and the dimension k2 of the second carrier 421 along the first direction is greater than the dimension k1 of the first carrier 411 of the first position adjustment mechanism 410 along the first direction.

[0131] 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.

[0132] 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. The battery swapping vehicle 1 can be parked on the first load-bearing platform 411 and the second load-bearing platform 421 after the first position adjustment mechanism 410 is moved to the target position. The battery swapping vehicle 1 is supported by the first load-bearing platform 411 and the second load-bearing platform 421, and the position of the battery swapping vehicle 1 in the second direction is adjusted on the first load-bearing platform 411 and the second load-bearing platform 421.

[0133] 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 greater 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.

[0134] 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, which will not be described in detail.

[0135] 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, or 200 mm.

[0136] In some embodiments, the second support platform 421 is used to support at least two wheels of the battery-swap vehicle 1 along the first direction.

[0137] 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 setting 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.

[0138] In some embodiments, along the first direction, the dimension k2 of the second carrying platform 421 is 1000 mm to 1500 mm; optionally, 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.

[0139] 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.

[0140] In this embodiment, the size of the second position adjustment mechanism 420 is 1000mm to 1500mm, and the wheels of various types of battery swapping vehicles can be located on the second position adjustment mechanism 420. For example, after a vehicle with a length of more than 4m, 6m or even 8m drives to the battery swapping platform, the rear wheels can be completely located on the second position adjustment mechanism 420. In addition, the second position adjustment mechanism 420 can achieve position adjustment of battery swapping vehicles 1 of different lengths by moving a small distance or not moving in the first direction.

[0141] In some embodiments, the second position adjustment mechanism 420 is movable along the first direction.

[0142] In this embodiment, the first position adjustment mechanism 410 and the second position adjustment mechanism 420 are both movable along the first direction, which is beneficial to further increase 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 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.

[0143] 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.

[0144] 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.

[0145] 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 that more types of battery-swap vehicles 1 are adapted.

[0146] In some embodiments, in combination Figure 7 and Figure 8As shown, 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, and the second direction is perpendicular to the first direction.

[0147] 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.

[0148] The preset position is the position where the battery-swapping vehicle 1 performs battery swapping, that is, the battery swapping position.

[0149] In some embodiments, the position calibration mechanism 460 includes a push rod mechanism 461, and the push rod mechanism 461 is used to push the battery-swap vehicle 1 to a preset position along the second direction.

[0150] After the battery swapping vehicle 1 enters the battery swapping platform, the battery swapping vehicle 1 may be skewed, or the body may be biased toward one side of the second direction of the battery swapping platform 200. Through the push rod mechanism 461, the body of the battery swapping vehicle 1 can be straightened, or the battery swapping vehicle 1 can be moved to a preset position along the second direction, so as to facilitate subsequent battery swapping operations.

[0151] In some embodiments, the first position adjustment mechanism 410 includes a first load-bearing platform 411, and the position adjustment device 400 also includes a second load-bearing platform 421. The first load-bearing platform 411 and the second load-bearing platform 421 are respectively used to support the wheels of the battery-swap vehicle 1 at different positions along the first direction, and at least one of the first load-bearing platform 411 and the second load-bearing platform 421 is provided with a plurality of rollers 462 arranged along the second direction.

[0152] 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.

[0153] 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 .

[0154] Optionally, combined Figure 7 and Figure 8 As shown, the push rod mechanism 461 includes a push rod 4611 and a push rod driving member (not shown in the figure), the push rod 4611 and the push rod driving connection, and the push rod 4611 is a rod extending along the first direction. Driven by the push rod driving member, the push rod 4611 moves along the second direction, thereby pushing the battery swap vehicle 1 to move along the second direction.

[0155] Optionally, after the push rod 4611 pushes the battery swap vehicle 1 to a preset position, the push rod 4611 returns to the 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, and the first end is an end close to the edge of the battery swap platform 200.

[0156] 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, or 500 mm.

[0157] Optionally, the movable range of the wheels of the battery-swap vehicle 1 along the second direction is 200 mm to 400 mm, for example, 200 mm, 350 mm, or 400 mm.

[0158] 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 swap 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 swap platform 200, which is conducive to improving the space utilization of the battery swap platform 200.

[0159] In some embodiments, in combination Figure 7 As shown, at least one of the first support platform 411 and the second support platform 421 is provided with two rows of rollers 462 opposite to each other in a first direction, and the two rows of rollers 462 are arranged to be inclined with each other to form a positioning groove for fixing the wheel. In this way, after the battery-swapping vehicle 1 moves to a preset position, the positioning groove formed by the rollers 462 is used to position and fix the battery-swapping vehicle.

[0160] Each column of rollers 462 includes a plurality of rollers 462 arranged along the second direction.

[0161] 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.

[0162] Fig. 9 is a schematic diagram of a first position adjustment mechanism according to an embodiment of the present application, Fig.10 for Fig. 9 Schematic diagram of the cross section along the BB direction. Optionally, as Fig. 9 and Fig.10 As shown, 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°.

[0163] 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.

[0164] Optionally, the diameter p1 of one roller 462 is 60 mm.

[0165] Optionally, the second support platform 421 includes two second sub-support platforms that are arranged opposite to each other and spaced apart along the second direction. The minimum distance D between two adjacent second sub-support platforms is min It can be 250mm~300mm, for example 250mm, 290mm, 300mm; the maximum distance D max It can be 2000mm~2300mm, for example, 2000mm, 2170mm, 2300mm.

[0166] Optionally, combined Figure 7 , Figure 8 and Fig.10 As shown, the two rows of rollers 462 on the first load platform 411 are arranged at an angle to each other to form a positioning groove for fixing the wheel, and the two rows of rollers 462 on the second load platform 421 are arranged horizontally. In this way, it is convenient to park the battery-swap vehicle on the first load platform 411 and the second load platform 421.

[0167] 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, and optionally, is 2170 mm. In this way, it is easy to adapt to battery-swap vehicles 1 of different vehicle widths and different wheel sizes.

[0168] In some embodiments, the position adjustment mechanism 400a also includes a third position adjustment mechanism. Along the first direction, the third position adjustment mechanism is located between the first position adjustment mechanism 410 and the second position adjustment mechanism 420. The third position adjustment mechanism is used to adjust the battery swap position of the battery swap vehicle 1 with the first position adjustment mechanism 410 or the second position adjustment mechanism 420.

[0169] For example, when the length of the battery swap vehicle 1 is relatively small, such as 3m to 4m, the front wheels of the battery swap vehicle 1 are parked on the third position adjustment mechanism, and the rear wheels of the battery swap vehicle 1 are parked on the second position adjustment mechanism 420. The position adjustment and positioning of the battery swap vehicle 1 are achieved through the third position adjustment mechanism and the second position adjustment mechanism 420.

[0170] For another example, when the length of the battery swap vehicle 1 is short and the battery swap vehicle 1 brakes late, causing the front wheels of the battery swap vehicle 1 to pass the third position adjustment mechanism, the front wheels of the battery swap vehicle 1 are parked at the first position adjustment mechanism 410, and the rear wheels of the battery swap vehicle 1 are parked at the third position adjustment mechanism, and the position adjustment and positioning of the battery swap vehicle 1 are achieved through the first position adjustment mechanism 410 and the third position adjustment mechanism.

[0171] In this embodiment, the position adjustment device 400 can be compatible with battery-swap vehicles with smaller vehicle lengths, such as micro vehicles.

[0172] Fig.11 Schematic diagram of a battery swap platform according to an embodiment of the present application. Fig.11 As shown, the position adjustment mechanism 400a includes at least three position adjustment mechanisms, which are arranged in sequence along the first direction, and at least two of the at least three position adjustment mechanisms are used to correspond to the wheels arranged at different positions along the first direction of the battery swapping vehicle 1. In this way, it is convenient to select the corresponding position adjustment mechanism to adjust the battery swapping position of the battery swapping vehicle 1 according to the length of the battery swapping vehicle 1.

[0173] Optionally, the positions of the at least three position adjustment mechanisms in the first direction are fixed.

[0174] In some embodiments, at least three position adjustment mechanisms include a fourth position adjustment mechanism 440, a fifth position adjustment mechanism 450, and a sixth position adjustment mechanism 460 arranged in sequence along the first direction, the sixth position adjustment mechanism 460 is arranged corresponding to the rear wheels of the battery swapping vehicle 1, the fourth position adjustment mechanism 440 is arranged corresponding to the front wheels of the battery swapping vehicle 1, and the fifth position adjustment mechanism 450 is arranged corresponding to other wheels located at the front and rear wheels of the battery swapping vehicle 1. In this way, it is convenient to select the corresponding position adjustment mechanism to carry the battery swapping vehicle 1 and adjust the position of the battery swapping vehicle 1 according to the length of the battery swapping vehicle 1.

[0175] Optionally, the at least three position adjustment mechanisms may also include four, five or more position adjustment mechanisms.

[0176] In some embodiments, the position adjustment device 400 further includes an adjustment mechanism 490, which is used to move the battery swap vehicle 1 to a preset position along a second direction, and the second direction is perpendicular to the first direction. After the battery swap vehicle 1 enters the battery swap platform 200, the battery swap vehicle 1 may deviate from the preset position. The adjustment mechanism 490 can move the battery swap vehicle 1 to the preset position, thereby facilitating subsequent battery swap operations.

[0177] 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.

[0178] 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 skewed body, or the body may be 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.

[0179] Optionally, at least one of the at least three position adjustment mechanisms includes a support platform, which is used to support the wheels of the battery-swap vehicle 1. The structure of the support platform is the same as the structure of the first support platform or the second support platform described above, and similar descriptions can be found above and in related drawings.

[0180] 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.

[0181] For another example, two rows of rollers are arranged on the support platform in a first direction and are arranged to be inclined with respect 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 are used to position and fix the battery-swapping vehicle.

[0182] For another example, the carrying platform is configured to be liftable.

[0183] The present application provides a battery swap station, comprising a position adjustment device 400 in any of the embodiments described above.

[0184] Fig.12 Schematic diagram of a battery replacement method according to an embodiment of the present application. Fig.12 As shown, the present application provides a battery replacement method 500, comprising the following steps.

[0187] Step 520 , before the battery swapping vehicle 1 enters the battery swapping platform 200 , adjust the position adjustment device 400 according to the information of the battery swapping vehicle 1 .

[0188] Different battery-swap vehicles 1 correspond to different position adjustment mechanisms in the position adjustment device 400 or the specific positions of the position adjustment mechanisms of the corresponding position adjustment devices 400 are different. Therefore, after obtaining the information of the battery-swap vehicle 1, before the battery-swap vehicle 1 enters the battery-swap platform 200, the position adjustment device 400 is adjusted to make the position adjustment device 400 adapt to the corresponding battery-swap vehicle 1.

[0189] The battery replacement method 500 of the present application can be executed by the control system of the battery replacement station.

[0190] In some embodiments, step 520 includes: moving the positions of several position adjustment mechanisms 400a to correspond to the information of the battery-swap vehicle 1; or, determining several position adjustment mechanisms 400a corresponding to the information of the battery-swap vehicle 1.

[0191] The plurality of position adjustment mechanisms 400a may be at least one position adjustment mechanism 400a.

[0192] The position adjustment device 400 includes a plurality of position adjustment mechanisms 400a that can adjust the position along the 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 swapping vehicle 1 according to the information of the battery swapping vehicle 1. In this way, after the battery swapping vehicle 1 enters the battery swapping platform, the battery swapping vehicle 1 can be located on the corresponding position adjustment mechanism 400a.

[0193] For example, step 520 can be applied to a position adjustment device 400 including a first position adjustment mechanism 410. After acquiring 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.

[0194] The position adjustment device 400 includes a plurality of position adjustment mechanisms 400a fixed in position along the 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 located on the corresponding position adjustment mechanism 400a.

[0195] 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 which are sequentially arranged and fixed along a first direction. The sixth position adjustment mechanism 460 corresponds to the rear wheel of the battery swapping vehicle 1, the fourth position adjustment mechanism 440 corresponds to the front wheel of the battery swapping vehicle 1, and the fifth position adjustment mechanism 450 corresponds to the wheel between the front wheel and the rear wheel of the battery swapping vehicle 1.

[0196] In this embodiment, it is convenient to adjust the position adjustment device 400 to be compatible with different types of battery-swap vehicles 1 according to the specific settings of the position adjustment device 400 and the information of the battery-swap vehicle 1 .

[0197] 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 .

[0198] 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.

[0199] 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 position adjustment device embodiment, and will not be elaborated here.

[0200] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application.
