Description

Technical Field

[0001] This utility model belongs to the field of vehicle battery swapping platform technology, specifically relating to a vehicle battery swapping positioning platform device suitable for different wheelbases. Background Technology

[0002] A battery swapping station is an energy station specifically designed to provide charging and battery replacement services for electric vehicles. Battery swapping refers to the process where an electric vehicle replaces its depleted battery with a fully charged one at the station, thus quickly replenishing its energy. Compared to traditional charging methods, battery swapping significantly reduces the time required to recharge, improves the convenience of using electric vehicles, and allows them to resume their journeys more quickly.

[0003] However, most current battery swapping stations have significant design flaws. They can only accommodate vehicles with a specific wheelbase, or provide battery swapping services only for models with similar wheelbases. This is mainly because the core battery swapping equipment, including the battery swapping robotic arm, vehicle positioning system, and battery swapping platform, is designed and debugged according to specific vehicle wheelbase standards. For example, the extension range and gripping position of the battery swapping robotic arm are set according to the battery layout of vehicles with a specific wheelbase; the calibration accuracy of the vehicle positioning system is also based on the wheel spacing and body dimensions of vehicles with a specific wheelbase.

[0004] When a vehicle's wheelbase does not match the preset compatibility range of a battery swapping station, a series of problems arise. The vehicle cannot be accurately parked in the designated position within the station, causing the battery swapping robotic arm to be unable to precisely engage with the vehicle's battery, thus hindering the battery swapping operation. This means that vehicles with incorrect wheelbases, even if they arrive at a swapping station, cannot receive battery swapping services and must find another suitable station, undoubtedly causing significant inconvenience to vehicle owners.

[0027] Optionally, a pressure sensor is provided on the roller, and the pressure sensor is electrically connected to the processing unit.

[0028] Optionally, the second adjustment mechanism further includes:

[0053] Parking platform 1, first positioning groove 101, second positioning groove 102, grid strip 103, first adjustment mechanism 2, V-shaped roller group 21, pusher 22, second adjustment mechanism 3, support frame 31, base plate 311, support strip 312, first connecting plate 313, second connecting plate 314, roller 32, lifting device 33, pressure sensor 34, electric push rod 35, push plate 36, guide rail 41, limit groove plate 42, rack 43, servo motor 44, gear 45, moving roller 46. Detailed Implementation

[0054] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0055] like Figure 1-8 As shown, a battery swapping positioning platform device suitable for vehicles with different wheelbases includes:

[0056] Parking platform 1 is used to park vehicles that need battery swapping. Parking platform 1 and the entire vehicle battery swapping positioning platform device are components of the battery swapping station and are compatible with other components used for battery swapping, such as replacing the robotic arm. These are not described or shown in detail in this embodiment.

[0057] The parking platform 1 has two first positioning slots 101 and two second positioning slots 102. The positions of the two first positioning slots 101 and the two second positioning slots 102 correspond to the individual wheels of the vehicle. The second positioning slots 102 are elongated so that the wheels of vehicles with different wheelbases can be parked in the first positioning slots 101 and the second positioning slots 102.

[0058] Two first adjustment mechanisms 2 are set inside the first positioning groove 101 for adjusting the wheels inside the first positioning groove 101;

[0059] Two second adjustment mechanisms 3 are disposed inside the second positioning groove 102 for adjusting the wheels within the second positioning groove 102;

[0060] The second adjustment mechanism 3 includes two sets of adjustment components and a moving component;

[0061] Two sets of adjustment components are disposed opposite to each other inside the second positioning groove 102 on the side closer to the first positioning groove 101 and inside the second positioning groove 102 on the side farther away from the first positioning groove 101, for adjusting the vehicle when in contact with the wheel;

[0062] The moving component is positioned between the two sets of adjustment components to control the contact between the two sets of adjustment components and the wheel.

[0063] The processing unit is electrically connected to the first adjustment mechanism 2 and the second adjustment mechanism 3 respectively, and is used to control the first adjustment mechanism 2 and the second adjustment mechanism 3 to adjust the vehicle.

[0064] The parking platform 1 features two first positioning slots 101 and two second positioning slots 102, whose positions precisely correspond to the individual wheels of the vehicle. The second positioning slots 102 are elongated to accommodate vehicles with different wheelbases. Whether it's a small vehicle with a short wheelbase or a large vehicle with a long wheelbase, its wheels can be smoothly positioned in the corresponding slots. This not only provides an initial parking position reference for the vehicle but also lays the foundation for more precise subsequent positioning adjustments. It ensures a unified starting positioning standard for different vehicle models on the battery swapping platform, avoiding parking confusion or the inability to perform positioning adjustments due to differences in vehicle wheelbase.

[0065] Two first adjustment mechanisms 2 are respectively installed inside the first positioning groove 101, and their main function is to make fine adjustments to the wheels within the first positioning groove 101. After the vehicle is parked in the positioning groove, the wheel position may deviate to some extent due to driver operation or other factors. The first adjustment mechanism 2 can make fine adjustments to the wheel position according to the instructions issued by the processing unit, such as adjusting the left and right deviations or angular deviations of the wheels. By accurately calibrating the position of the vehicle's front wheels, it ensures that the vehicle's front wheels are in the optimal state for battery swapping.

[0066] The two sets of adjustment components in the second adjustment mechanism 3 are positioned opposite each other inside the second positioning groove 102, near and far from the first positioning groove 101. When the adjustment components contact the wheel, they can adjust the vehicle in all directions. After the vehicle is parked, if the vehicle shifts, the adjustment components can correct the vehicle's position and attitude by moving themselves, such as horizontally, pushing the wheel. This ensures that the vehicle remains stable during the battery swapping process, guaranteeing a smooth operation. The coordinated adjustment of the first adjustment mechanism 2 and the second adjustment mechanism 3 allows the vehicle to reach the predetermined position for battery swapping.

[0067] The moving component, positioned between the two sets of adjustment components, plays a crucial role in controlling the contact between these components and the wheels. It precisely controls the distance and speed at which the adjustment components move towards the wheels, based on the vehicle's actual condition. Once the wheelbase is determined, the moving component quickly moves the adjustment components to the appropriate position to contact the wheels, preventing collisions or incomplete contact. This achieves precise adjustment of the rear wheels, working in conjunction with the first adjustment mechanism to complete the overall vehicle positioning.

[0068] The processing unit, acting as the "brain" of the entire battery swapping positioning platform, is electrically connected to both the first adjustment mechanism 2 and the second adjustment mechanism 3. It receives vehicle position information from various sensors, analyzes and calculates it, and then issues precise control commands to the first and second adjustment mechanisms. The processing unit coordinates the actions of each adjustment mechanism, ensuring they operate according to predetermined programs and strategies. For example, based on vehicle wheelbase information, the processing unit controls the adjustment range and sequence of the first and second adjustment mechanisms, ensuring that vehicles with different wheelbases can quickly and accurately reach the ideal battery swapping position, improving the accuracy and efficiency of battery swapping, reducing swapping time, and enhancing the overall operational capability of the battery swapping station. Specifically, the processing unit can be the processor of the battery swapping station or a separately configured programmable logic controller (PLC).

[0069] Furthermore, a grid strip 103 is provided inside the second positioning groove 102 along the length direction of the second positioning groove 102, and the grid strip 103 is recessed.

[0070] The adjustment components include:

[0071] Support frame 31, which is matched with grid strip 103;

[0072] Multiple rollers 32 are rotatably mounted on the support frame 31, and each roller 32 corresponds to a gap in the grid strip 103 so that the roller 32 can pass through the grid strip 103.

[0073] The lifting device 33 is located at the end of the support frame 31 away from the parking platform 1, and the lifting device 33 is electrically connected to the processing unit for lifting and adjusting the assembly.

[0074] The grille strip 103 is recessed along the length of the second positioning groove 102, providing a specific working space and movement track for the adjustment assembly. Simultaneously, its slit structure provides a channel for the roller 32 to pass through, allowing the adjustment assembly to contact the wheel and perform adjustments. This also prevents the wheel from directly running over the adjustment assembly after entering the second positioning groove 102. Compared to the adjustment assembly, the wheel is suspended, allowing for subsequent contact and adjustment by the adjustment assembly.

[0075] The support frame 31 is matched with the grid strip 103. This matching ensures that the support frame 31 can be stably installed within the space provided by the grid strip 103, forming an organic whole with the grid strip 103. As the basic support structure of the adjustment assembly, the support frame 31 provides a platform for the installation and rotation of the roller 32, ensuring that the roller 32 can work in the predetermined position and manner. At the same time, it also serves to connect and fix other components, making the entire adjustment assembly a stable structure.

[0076] Multiple rollers 32 are rotatably mounted on a support frame 31, with each roller 32 corresponding to a gap in the grille strip 103. This allows the rollers 32 to accurately pass through the gaps in the grille strips, supported by the support frame. When the rollers 32 pass through the grille strip 103 and contact the vehicle's wheels, the rotational characteristics of the rollers reduce friction between them and the wheels. When adjusting the vehicle's position, the wheels can move more smoothly under the action of the rollers, enabling fine-tuning of the vehicle's position and improving the accuracy of vehicle positioning.

[0077] The lifting device 33 is located at the end of the support frame 31 furthest from the parking platform 1 and is electrically connected to the processing unit. This allows the processing unit to control the operation of the lifting device 33 by sending an electrical signal. The main function of the lifting device 33 is to control the raising and lowering of the adjustment assembly. When vehicle adjustment is required, the processing unit issues a command, and the lifting device 33 raises the adjustment assembly, allowing the roller 32 to pass through the grille bar and contact the wheel. Simultaneously, the wheel is lifted so that it no longer contacts the grille bar 103, but only the roller 32, further reducing unnecessary friction on the wheel during adjustment. After adjustment, the lifting device 33 lowers the adjustment assembly, separating it from the wheel. This controllable raising and lowering function allows the adjustment assembly to flexibly contact and disengage from the wheel according to actual needs, enhancing the adaptability and flexibility of the battery swapping station for adjusting different vehicles.

[0078] Specifically, in one alternative embodiment, the lifting device 33 can be a hydraulic lifting system, a pneumatic lifting device, or a screw jack.

[0079] Specifically, the support frame 31 includes:

[0080] The base plate 311 is located on the side of the grille strip 103 away from the parking platform 1;

[0081] Multiple support bars 312 are set on the base plate 311, and each support bar 312 passes through the gap of the grid bar 103.

[0082] The first connecting plate 313 is mounted on the base plate 311;

[0083] The second connecting plate 314 is disposed at the end of each support bar 312 away from the base plate 311;

[0084] Each roller 32 passes through the gaps in the grid strip 103 and is connected to the first connecting plate 313 and the second connecting plate 314 respectively.

[0085] The base plate 311, located on the side of the grille strip 103 away from the parking platform 1 and on the side of the parking platform 1 where no vehicle is parked, serves as the bottom support structure of the support frame 31 and has a large planar area. It provides a stable foundation for the entire support frame 31, bearing the pressure from the components above and from the contact between the rollers and the wheels. Its relative position to the grille strip 103 ensures that the support frame 31 can be accurately installed in the second positioning groove and forms a stable fit with the grille strip 103, preventing the support frame from shaking or shifting during operation.

[0086] Multiple support strips 312 are mounted on the base plate 311 and pass through the gaps in the grid strips 103. These support strips have a certain length and strength and extend upwards perpendicular to the base plate 311. On the one hand, the support strips 312 serve to connect the base plate 311 and the second connecting plate 314, transferring the supporting force of the base plate to the structure above. On the other hand, the support strips passing through the gaps in the grid strips 103 further enhance the stability of the fit between the support frame 31 and the grid strips 103, while also providing space and support points for the installation of the rollers 32, ensuring that the rollers can accurately pass through the grid strips and contact the wheels.

[0087] The first connecting plate 313 is mounted on the base plate 311 and is tightly connected to the base plate 311. As a connection point for the roller 32, the first connecting plate 313 provides a position for mounting and fixing one end of the roller. Its connection with the base plate 311 ensures the stability of the roller during rotation, prevents the roller from shifting in the horizontal direction, and ensures that the roller can accurately contact the wheel and perform its adjustment function.

[0088] The second connecting plate 314 is located at the end of each support bar 312 furthest from the base plate 311, and is tightly connected to the support bar 312 to form an integral structure. The second connecting plate 314 provides a mounting and fixing position for the other end of the roller 32, and works together with the first connecting plate 313 to firmly mount the roller 32 onto the support frame 31. Its position and structural design ensure that the roller can rotate in a stable plane and maintain good contact with the wheel, thereby achieving effective adjustment of the vehicle position.

[0089] The roller 32, connected to the first connecting plate 313 and the second connecting plate 314, obliquely passes through the gaps in the grille strip 103, forming a V-shape when the rollers 32 on the two adjustment components approach and contact the wheel. During the lifting and lowering process controlled by the lifting device 33, the V-shape provides excellent balance and stability. When the roller 32 obliquely passes through the gaps in the grille strip 103 to form a V-shape, the force exerted on the wheel by the rollers on both sides is relatively uniform. During lifting and lowering, this uniform force prevents the wheel from swaying or deviating due to uneven force, allowing the vehicle to rise or fall smoothly. This is crucial for the safety and stability of the battery swapping process, reducing potential damage to the battery swapping equipment or inaccurate battery installation caused by vehicle swaying.

[0090] Furthermore, a pressure sensor 34 is provided on the roller 32, and the pressure sensor 34 is electrically connected to the processing unit. The pressure sensor 34 is used to sense whether the roller 32 is in contact with the wheel, and when the roller 32 moves towards the wheel, the pressure sensor 34 will sense pressure when the roller 32 contacts the wheel, thereby determining that the roller 32 has made contact with the wheel and stopping its movement.

[0091] Pressure sensor 34 is mounted on roller 32, and its core function is to accurately sense whether roller 32 is in contact with the wheel. During battery swapping operations, roller 32 needs to precisely align with the wheel to achieve vehicle positioning and adjustment, and pressure sensor 34 can monitor this contact status in real time, providing crucial information for subsequent operations.

[0092] Pressure sensor 34 is electrically connected to the processing unit. When roller 32 moves towards and contacts the wheel, pressure sensor 34 senses the pressure change and sends this information back to the processing unit. Based on this feedback signal, the processing unit controls roller 32 to stop moving, preventing excessive pressure on the wheel and ensuring proper contact between the roller and wheel, preparing for subsequent vehicle adjustment operations. By accurately determining the contact condition between roller 32 and wheel using pressure sensor 34, damage to the wheel or vehicle from excessive roller movement is avoided, ensuring vehicle safety during battery swapping. Simultaneously, it reduces the risk of damage to the battery swapping equipment itself due to improper operation, extending the equipment's lifespan.

[0093] Specifically, as the roller 32 moves toward the wheel, the pressure sensor 34 continuously collects pressure data on the roller surface. When the roller is not in contact with the wheel, the pressure value detected by the pressure sensor is at a relatively stable low level; however, when the roller comes into contact with the wheel, the pressure sensor immediately detects a significant change in pressure.

[0094] Pressure sensor 34 converts the collected pressure data into an electrical signal and transmits the signal to the processing unit via an electrical connection. The processing unit receives the signal and analyzes and processes it.

[0095] The processing unit determines whether the roller 32 has contacted the wheel based on the received pressure signal. If it determines that the roller 32 has contacted the wheel, the processing unit will immediately issue a control command to stop the movement of the roller 32 (and control the moving component to stop the movement of the adjusting component). At this time, the roller 32 contacts the wheel and the moving component reaches the predetermined position.

[0096] Furthermore, the second adjustment mechanism also includes:

[0097] Two electric push rods 35 are respectively arranged opposite to each other on the parking platform 1, and the electric push rods 35 are electrically connected to the processing unit.

[0098] Two push plates 36 are connected to electric push rods 35 respectively and are matched with the second positioning groove 102.

[0099] Two electric actuators 35 are positioned opposite each other on the parking platform 1 and are electrically connected to the processing unit. This relative arrangement provides symmetrical and stable thrust for subsequent adjustment actions. The electric actuator 35 is an electric drive device that converts the rotary motion of an electric motor into the linear reciprocating motion of the actuator. The processing unit can precisely control the extension and retraction of the electric actuator by sending electrical signals, including parameters such as the extension length, speed, and force.

[0100] Two push plates 36 are respectively connected to the electric push rod 35 and matched with the second positioning groove 102. The push plate 36 is a component that directly acts on the vehicle. Its shape and size are designed to adapt to the second positioning groove 102 and the adjustment component, ensuring that they do not interfere with each other when the adjustment component is raised. Specifically, the range of motion of the push plate 36 and the raising range of the adjustment component are designed to not overlap, so as to ensure that the vehicle located in the second positioning groove 102 can be accurately adjusted when the electric push rod is pushed.

[0101] Specifically, after a vehicle enters the battery swapping station and parks on the parking platform 1, it undergoes initial positioning via the adjustment components (second adjustment mechanism 3) and the first adjustment mechanism 2, as well as positioning in the vehicle's entry direction. However, there may still be a positional deviation in the left-right direction, which cannot fully meet the precision requirements of battery swapping. At this time, the processing unit sends a control signal to the electric push rod 35 based on the vehicle's actual position information. Upon receiving the signal, the electric push rod 35 begins to extend and retract, pushing the connected push plate 36 towards the vehicle. After the push plate 36 contacts the vehicle, it applies a thrust to the vehicle, allowing the wheels to move on the rollers 32, easily completing the left-right adjustment of the vehicle, thereby further refining the vehicle's position and ensuring that the vehicle is in the predetermined battery swapping location.

[0102] Furthermore, the mobile component includes:

[0103] The guide rail 41 is located on the side of the lifting device 33 away from the support frame 31 and is parallel to the second positioning groove 102;

[0104] Multiple limiting slots 42 are fixedly installed on two lifting devices 33 respectively, and the limiting slots 42 are matched with the guide rails 41.

[0105] The rack 43 is located on the side of the lifting device 33 away from the support frame 31 and is arranged parallel to the guide rail 41;

[0106] Two servo motors 44 are respectively mounted on two lifting devices 33, and the servo motors 44 are electrically connected to the processing unit. The output shafts of the two servo motors 44 are equipped with gears 45, which are matched with racks 43.

[0107] The guide rail 41 is located on the side of the lifting device 33 away from the support frame 31. It provides the basic path for the movement of the entire moving assembly and is a guide component with specific shape and precision requirements. The main function of the guide rail 41 is to provide a sliding track for the limiting groove plate 42, ensuring that the adjusting assembly moves linearly in a predetermined direction during movement, thus guaranteeing the accuracy and stability of the movement. It restricts the degree of freedom of movement of the adjusting assembly, preventing it from deviating or wobbling during movement, thereby enabling the adjusting assembly to accurately reach the designated position and contact the wheel.

[0108] Multiple limiting groove plates 42 are fixedly mounted on the two lifting devices 33 and matched with the guide rail 41. The limiting groove plates typically have grooves or protrusions that conform to the shape of the guide rail. The limiting groove plates 42, in cooperation with the guide rail 41, serve a dual function of guiding and limiting. They slide on the guide rail, allowing the lifting device 33 and its connected adjusting components to move smoothly along the guide rail. Simultaneously, the structural design of the limiting groove plates prevents the adjusting components from disengaging from the guide rail during movement, ensuring the safety and reliability of the entire movement process.

[0109] The rack 43 is located on the side of the lifting device 33 away from the support frame 31 and is arranged parallel to the guide rail 41. A rack is a strip-shaped part with equally spaced teeth. The rack 43 provides the basis for the meshing of the gear 45 and is a key component for realizing power transmission and motion control. Through its cooperation with the gear 45, the rotational motion of the servo motor 44 is converted into the linear motion of the adjustment component, thereby driving the adjustment component to move along the guide rail. Simultaneously, it allows the adjustment component to stop at any position on the gear 45, thus adapting to vehicles with different wheelbases.

[0110] Furthermore, the limiting groove plate 42 is provided with a movable roller 46 inside.

[0111] The reduction in friction allows the limiting slot plate 42 to move more smoothly on the guide rail 41. This means that the servo motor 44 does not need to provide excessive power to overcome friction, reducing the motor load. On the one hand, this reduces energy consumption and improves the energy efficiency of the entire system; on the other hand, it also reduces wear on the motor and other transmission components, extending the service life of the equipment.

[0112] Furthermore, the first adjustment mechanism 2 includes:

[0113] Two V-shaped roller groups 21 are respectively set inside the two first positioning grooves 101;

[0114] Two pushers 22 are respectively installed on the parking platform 1, and the pushers 22 are electrically connected to the processing unit. The two pushers 22 are respectively matched with the two first positioning slots 101 and the V-shaped roller group 21.

[0115] Two V-shaped roller assemblies 21 are respectively disposed inside the two first positioning grooves 101. The V-shaped roller assembly is usually composed of multiple rollers arranged in a V-shape. This unique shape design enables it to produce a special guiding effect when in contact with the wheel.

[0116] Similarly, two pushers 22 are mounted on the parking platform 1 and electrically connected to the processing unit. The function of the pushers is to easily cooperate with the V-shaped roller assembly 21 to push the wheels and vehicle when the wheels are parked in the V-shaped roller assembly 21, enabling them to perform corresponding actions and thus adjust the vehicle's left and right position. Each pusher 22 matches a corresponding first positioning slot 101 and V-shaped roller assembly 21 to achieve vehicle adjustment. The pusher 22 also includes a push rod and a push plate. Both the pusher 22 and the V-shaped roller assembly 21 are common adjustment structures in existing battery swapping systems, and their detailed structures will not be described here.

[0117] In the actual operation of a battery swapping station, the specific usage of this device for battery swapping positioning of vehicles with different wheelbases is as follows:

[0118] Vehicle parking: The driver drives the vehicle requiring battery swapping into the battery swapping station and parks the vehicle on parking platform 1. Parking platform 1 is equipped with two first positioning slots 101 and two second positioning slots 102. The second positioning slots 102 are designed in a long strip shape to ensure that the wheels of vehicles with different wheelbases can be smoothly parked in the corresponding positioning slots, completing the initial parking positioning of the vehicle and laying the foundation for subsequent precise adjustments.

[0119] Initial positioning of the first adjustment mechanism: After the vehicle is properly parked, the first adjustment mechanism 2, located in the first positioning groove 101, begins to operate. The first adjustment mechanism 2 consists of two V-shaped roller sets 21 and two pushers 22. The front wheels of the vehicle are placed in the V-shaped roller sets 21. The V-shaped structure of the V-shaped roller sets 21 plays a positioning role, so that the front wheels do not need to be moved or adjusted in the front and rear directions, and the position of the front wheels is initially fixed.

[0120] The second adjustment mechanism approaches the wheel: For vehicles with different wheelbases, the moving component in the second adjustment mechanism 3 is activated. The moving component includes a guide rail 41, a limiting slot plate 42, a rack 43, two servo motors 44, and a gear 45. The processing unit (such as the processor or programmable logic controller of the battery swapping station) sends control commands to the servo motors 44 based on the vehicle wheelbase information. The servo motors 44 operate, and the gear 45 on their output shaft meshes with the rack 43, driving the lifting device 33 and the adjustment component to move along the guide rail 41. The limiting slot plate 42 fits tightly with the guide rail 41, ensuring smooth movement of the adjustment component, preventing it from deviating from the track during movement, and ensuring that the adjustment component accurately approaches the wheel located in the second positioning slot 102.

[0121] Pressure sensor detection and adjustment component operation: During the movement of the adjustment components toward the wheel, the pressure sensor 34 on the roller 32 plays a crucial role. The pressure sensor 34 monitors the contact state between the roller 32 and the wheel in real time and converts the collected pressure data into electrical signals, which are continuously transmitted to the processing unit. When one of the rollers 32 of the adjustment components contacts the wheel, the pressure sensor 34 on that roller 32 detects the pressure change, generates a pressure signal, and transmits it to the processing unit. After receiving the signal, the processing unit quickly analyzes and determines whether to issue a stop command to the servo motor 44 associated with the adjustment component to which the pressure sensor 34 belongs, causing that adjustment component to stop moving. At this time, the other adjustment component, which has not yet contacted the wheel, continues to approach the wheel under the drive of the moving component until both adjustment components contact and clamp the wheel from both sides, preparing for the subsequent lifting operation.

[0122] Wheel Lifting and Overall Vehicle Adjustment: After the two adjustment components successfully clamp the wheels, the lifting device 33 in the adjustment components begins to operate. The lifting device 33 is located at the end of the support frame 31 away from the parking platform 1 and is electrically connected to the processing unit. The processing unit issues a command to control the lifting device 33 to start, raising the adjustment components so that the roller 32 passes through the grille bar 103, thereby lifting the wheels. At this time, all four wheels of the vehicle are located on the rollers (the rollers 32 of the second adjustment mechanism and the rollers of the V-shaped roller group 21), and the wheels are no longer in contact with the grille bar 103, effectively reducing friction during subsequent adjustments. Subsequently, the processing unit controls the pusher 22 and the electric push rod 35 to operate. The pusher 22, in conjunction with the V-shaped roller group 21, pushes the front wheels; the electric push rod 35 pushes the push plate 36 connected to it, and the push plate 36 matches the second positioning groove 102, applying a pushing force to the rear wheels. Because the rollers of roller 32 and V-shaped roller assembly 21 can reduce the friction of the wheel moving left and right, the vehicle can more easily adjust its left and right position and achieve precise positioning under the push of pusher 22 and electric push rod 35.

[0123] Battery swapping operation execution: After the vehicle completes left and right position adjustment and precise positioning, the battery swapping equipment at the battery swapping station (such as a battery replacement robotic arm) starts according to a preset program to perform the battery swapping operation on the vehicle. After the battery replacement is completed, the vehicle can leave the battery swapping station, and the entire battery swapping and positioning process is completed. The above embodiments are only illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
