Description

Technical Field

[0001] This application relates to the field of battery swapping stations for electric vehicles, specifically a battery swapping mechanism for a battery swapping station. Background Technology

[0002] Battery swapping stations are facilities that provide rapid battery replacement services for electric vehicles. Users can remove the depleted battery and replace it with a fully charged one, which can restore the vehicle's range in a short time. Compared with charging, this significantly shortens the charging time, improves vehicle efficiency, helps solve the range anxiety problem of electric vehicles, and promotes the popularization and development of electric transportation.

[0003] However, existing technologies have found that when a car arrives at the battery swapping platform, multiple hydraulic rods and rollers are usually used to center and align the vehicle to achieve positioning. However, when multiple hydraulic rods are used, their synchronization is low, making it difficult to ensure that the vehicle is in the center position, resulting in insufficient positioning accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a battery swapping mechanism for a battery swapping station. This mechanism allows the vehicle's tires to move along the roller assembly through the continuous movement of a push rod, achieving vehicle centering and thus improving positioning accuracy during battery swapping. This solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a battery swapping mechanism for a battery swapping station, comprising: Battery swapping platform and drive components; The battery swapping platform is equipped with four roller sets for vehicle tires to rest on, and the rolling axis of the roller sets is perpendicular to the axis of the tires. The drive assembly includes a drive motor, a bidirectional threaded rod, a slider, and a push rod; The bidirectional threaded rod extends in a direction perpendicular to the rolling shaft, and both reverse threads are threadedly connected to a slider. The push rod is fixedly connected to the slider and corresponds to one of the roller groups for pushing the tire to move.

[0006] Preferably, the drive assembly further includes a limiting plate and a guide rod; One end of the guide rod is fixedly connected to the side of the push rod facing away from the tire, and the other end passes through the limiting plate and is connected to the drive motor. The limiting plate is slidably connected to the guide rod; The limiting plate is fixed to the flatbed of the vehicle that allows the vehicle to drive into the battery swapping platform.

[0007] Preferably, the drive assembly further includes a polyurethane buffer plate; The polyurethane buffer plate is fixedly connected to the side of the push rod facing the tire.

[0008] Preferably, the drive assembly further includes a fixing block; The fixing block is fixed to a plane of the battery swapping platform that is away from the vehicle's load-bearing surface; The bidirectional threaded rod passes through the fixed block and is rotatably connected to the fixed block.

[0009] Preferred options also include: A protective shell is fixedly connected to the overhead crane flatbed and covers the guide rod and the limiting plate.

[0010] Preferred options also include: Base plate, side plates, slide rails, and battery swapping robot; The two sides of the base plate are fixedly connected to the overhead flatbed via the side plate, forming a square sliding channel; The slide rail extending in the direction of the rolling shaft is fixed to the surface of the base plate facing the flatbed of the vehicle. The battery swapping robot is slidably connected to the slide rail.

[0011] Preferably, the battery swapping robot also includes a camera module; The camera module is fixed to the battery swapping robot.

[0012] Preferably, the roller assembly includes a mounting frame and a plurality of rollers arranged at equal intervals; The roller is rotatably connected to the mounting frame; The mounting frame is fixedly connected to the battery swapping platform.

[0013] Preferably, the overhead crane flatbed has a groove extending in a direction perpendicular to the rolling axis; The slider is slidably connected to the groove.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects: This solution achieves mechanical synchronization and automation of vehicle positioning through a drive assembly consisting of a drive motor, a bidirectional threaded rod, sliders, and push rods. Specifically, after the vehicle tires rest on the roller assembly of the battery swapping platform, the drive motor is activated to rotate the bidirectional threaded rod. Since the two opposing threads of this rod each engage with a slider, its rotation directly forces the two sliders to move precisely and synchronously in opposite directions along the axis of the threaded rod. This movement is directly transmitted to the tires via the push rods. Because the rolling direction of the roller assembly is perpendicular to the pushing direction of the push rods, the tires can roll along the rollers with low resistance when subjected to lateral thrust, thus being smoothly and forcibly adjusted to the preset centering position. Throughout the process, the single power source and the inherent synchronous characteristics of the machinery fundamentally eliminate the response delay or asynchrony problems that may occur with multiple independent actuators, thereby achieving rapid and accurate vehicle centering and laying a solid foundation for subsequent battery swapping operations.

[0015] This solution achieves precise positioning while fully considering the interaction between the actuator and the tire, enabling non-destructive positioning. The key is that the actuator pushing the tire is a push rod that moves in a specific direction, rather than directly driving rollers that might generate friction. The tire rests on a freely rotating roller assembly, and its contact with the platform is through rolling friction, resulting in minimal resistance. When the push rod, driven by the slider, contacts the tire sidewall, the tire adjustment process is completed jointly by the lateral thrust of the push rod and the rolling action provided by the roller assembly. This "push-roll" combined adjustment method makes tire movement smooth and effortless, avoiding severe sliding friction between the tire rubber and the platform surface, thus effectively preventing scratches or wear on the tire sidewall during positioning and protecting vehicle components.

[0016] This battery swapping station's battery swapping mechanism includes components such as rollers, sliders, push rods, and bidirectional threaded rods. When a vehicle travels above the corresponding roller group, the corresponding drive motor is activated. The drive motor rotates the corresponding bidirectional threaded rod, which in turn moves the corresponding slider. Simultaneously, the corresponding connecting rod, push rod, and polyurethane buffer plate move relative to each other, allowing the polyurethane buffer plate to contact the vehicle's tires and preventing damage from hard impacts. Through the continuous movement of the push rod and its coordination with the roller group, the vehicle's tires move along the roller group, aligning the vehicle in the center. This improves the positioning accuracy during battery swapping. Attached Figure Description
