[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 6As shown, this invention provides a battery swapping station for new energy vehicles, including a main body 1. A ramp 2, facilitating vehicle entry, is fixed to the wheel inlet of the main body 1 with screws. A supporting hydraulic cylinder 6 is fixed to the bottom of the inner surface of the main body 1 with screws. A support platform 3 is fixed to the top of the supporting hydraulic cylinder 6 with screws. The supporting hydraulic cylinder 6 is located at the corner of the lower surface of the support platform 3. The ramp 2 is symmetrically arranged on both sides of the support platform 3. A positioning device 7 is provided on the outer surface of the support platform 3. The positioning device 7 includes a positioning element slidably mounted on the upper end of the support platform 3. Block 71, a battery swapping mechanism 4 is provided at the bottom of the inner surface of the battery swapping station body 1. The battery swapping mechanism 4 is located directly below the support platform 3. A vehicle model recognition device 5 is fixed to the top of the inner surface of the battery swapping station body 1 by screws. A safety device 8 is provided on the lower surface of the support platform 3. The safety device 8 includes a fixing block 81 fixed to the bottom of the inner surface of the battery swapping station body 1 by screws, and a connecting sleeve 82 fixedly connected to the lower surface of the support platform 3. The fixing block 81 is slidably disposed in the groove at the lower end of the connecting sleeve 82, and a rotating locking block 88 for limiting the position is provided in the connecting sleeve 82.

[0024] Among them, the vehicle model recognition device 5 and the battery swapping mechanism 4 are existing technologies, and their structural principles will not be described in detail. The vehicle model recognition device 5 is a vehicle model recognition equipment product of Xinluwei Company. The present invention also includes interactive systems, visual cameras and communication modules, etc. Since they are not the main technologies of the present invention, they will not be described in detail. The material of the connecting arc plate 89 is a deformable elastic steel plate, and its thickness and elasticity can be set according to actual needs.

[0025] The telescopic hydraulic cylinder 74 is controlled by a pump station, thereby enabling the four telescopic hydraulic cylinders 74 to be synchronized.

[0026] It should be noted that the vehicle identification device 5 of the present invention includes, but is not limited to, being installed inside the main body 1 of the battery swapping station, and can also be installed on the outside of the main body 1 of the battery swapping station, on the passage where vehicles enter the main body 1 of the battery swapping station. Multiple devices can be installed to capture information such as the width of both sides of the vehicle and the number of axles. Its design position can be set according to actual needs.

[0027] During use, the vehicle travels from the ramp 2 onto the support platform 3. During this process, the vehicle type recognition device 5 identifies the vehicle type, and the data is transmitted to the control terminal. Based on the vehicle size, the device drives the telescopic hydraulic cylinder 74, which in turn drives the positioning block 71 to slide along the support platform 3 to adjust the distance between the positioning blocks 71. This facilitates adaptation to the front and rear tire distances of different vehicles, improving the adaptability of the device. After the vehicle travels onto the support platform 3, the four tires are placed in the recesses on the corresponding positioning blocks 71, so that the vehicle stops directly above the battery swapping mechanism 4. This facilitates the battery swapping operation, allows for more precise control of the vehicle's stopping position, improves battery swapping efficiency, and saves battery swapping time. The anti-slip pillars 73 prevent wheel slippage when the vehicle stops on the positioning blocks 71, thus improving safety.

[0028] If the device malfunctions and causes the support platform 3 to fall, the connecting sleeve 82 is fitted onto the outer surface of the fixed block 81 and moves downward. The top of the inner surface of the groove 83 contacts and presses the top of the connecting arc plate 89. The connecting arc plate 89 presses the rotating locking block 88 to rotate and open to both sides. At the same time, the movable support rod 85 moves downward to the bottom of the groove inside the fixed block 81. At this time, the telescopic spring 86 is compressed to its maximum limit, and the rotating locking block 88 is fully opened and locked into the limiting slot 84, so that the position of the connecting sleeve 82 is limited, and the support platform 3 stops falling. It can have an emergency stop function, preventing the vehicle from falling with the support platform 3 and causing danger, thus providing a safety function. Through the provided telescopic spring 86, most of the impact force during the fall can be converted into elastic potential energy and stored to reduce the impact on the vehicle, further improving the protection.

[0029] like Figure 2 , 4 As shown, the positioning device 7 also includes a bent sliding plate 72 fixed to the outer surface of the positioning block 71 by screws. The outer surface of the bent sliding plate 72 is slidably connected to the outer surface of the support platform 3. The present invention uses the bent sliding plate 72, which is slidably connected to the support platform 3 via a slide rail installed on the outer surface of the support platform 3, to facilitate the sliding of the positioning block 71 along the support platform 3, thereby adjusting the distance between the positioning blocks 71. To make the sliding of the positioning block 71 smoother, lubricating oil is applied between the contact surfaces of the support platform 3 and the positioning block 71, or a rotatable shaft is provided at the upper end of the support platform 3, thereby reducing the friction between the support platform 3 and the positioning block 71.

[0030] like Figure 2 , 4As shown, the bending slide plate 72 is symmetrically arranged on both sides of the positioning block 71. Anti-slip posts 73 are fixed to the recessed areas on the upper surface of the positioning block 71 by screws. A telescopic hydraulic cylinder 74 is fixedly connected to the outer surface of the support platform 3, and the output end of the telescopic hydraulic cylinder 74 is fixedly connected to the outer surface of the bending slide plate 72. This invention utilizes the telescopic hydraulic cylinder 74, whose outer surface is welded to the outer surface of the support platform 3, and whose output end is welded to the outer surface of the bending slide plate 72, to provide a driving function, enabling the positioning block 71 to slide along the support platform 3.

[0031] like Figure 3 , 5 As shown in Figure 6, the safety device 8 also includes an internal groove 83 provided inside the connecting sleeve 82. The inner surface of the internal groove 83 abuts against the outer surface of the fixing block 81 and can slide longitudinally. In this invention, the top of the connecting sleeve 82 is welded to the lower surface of the support platform 3. If the device malfunctions and causes the support platform 3 to fall, the connecting sleeve 82 moves downward and fits onto the outer surface of the fixing block 81, cooperating with the fixing block 81 to provide support.

[0032] like Figure 3 , 5 As shown in Figure 6, a limiting groove 84 is formed on the inner surface of the groove 83. A movable support rod 85 is slidably connected to the groove in the middle of the fixed block 81. The top of the movable support rod 85 is rotatably connected to the rotating block 88 by a pin. The outer surface of the rotating block 88 is pressed and adapted to the inner surface of the limiting groove 84. A connecting arc plate 89 is fixedly connected to the upper surface of the rotating block 88. In this invention, the rotating block 88 is connected to the top of the movable support rod 85 by a rotating shaft. The bottom of the connecting arc plate 89 is welded to the upper surface of the rotating block 88. When the rotating block 88 is fully opened and locked into the limiting groove 84, it has a limiting function.

[0033] like Figure 3 , 5 As shown in Figure 6, a fixing plate 87 is fixed to the outer surface of the movable support rod 85 by screws. A telescopic spring 86 is sleeved on the outer surface of the movable support rod 85. The end of the telescopic spring 86 is fixed to the lower surface of the fixing plate 87 by screws and a retaining plate (not shown in the figure). The end of the telescopic spring 86 away from the fixing plate 87 is fixedly connected to the upper surface of the fixing block 81. This invention, through the telescopic spring 86, with its two ends welded to the outer surfaces of the fixing plate 87 and the fixing block 81 respectively, can convert most of the impact force during descent into elastic potential energy, thereby reducing the impact on the vehicle.

[0034] Principle of this invention:

[0035] In use, the vehicle travels from the ramp 2 onto the support platform 3. During the vehicle's movement, the vehicle type recognition device 5 identifies the vehicle type and external parameters, and the data is transmitted to the control terminal. The terminal connects to the internet via a communication module to retrieve vehicle parameters. It can also interact with the vehicle via a communication and interactive system, allowing for interactive vehicle information exchange. This enables the internal system of the swapping station to drive the telescopic hydraulic cylinder 74 according to the vehicle size. The telescopic hydraulic cylinder 74 drives the positioning block 71 to slide along the support platform 3, adjusting the distance between the two positioning blocks 71 to accommodate the front and rear tire distances of different vehicles, thus improving the device's adaptability. In terms of configuration, after the vehicle drives onto the support platform 3, the four tires are placed in the recesses on the corresponding positioning blocks 71, so that the position of the power battery under the vehicle stops directly above the battery swapping mechanism 4. This facilitates the battery swapping mechanism 4 to perform battery swapping operations on the vehicle, makes it easier to control the stopping position of the vehicle more precisely, improves battery swapping efficiency, and saves battery swapping time. The anti-slip pillars 73 prevent the wheels from slipping when the vehicle stops on the positioning blocks 71. At the same time, after the vehicle is swapped, they can increase the friction of the wheels, allowing them to pass smoothly, thereby improving safety.

[0036] When the support platform 3 falls, if the device malfunctions, the connecting sleeve 82, which is fitted onto the outer surface of the fixed block 81 and can move downwards, will cause the top of the inner surface of the groove 83 to contact and press the top of the connecting arc plate 89. The connecting arc plate 89 will press the rotating locking block 88 to rotate and open to both sides around the pin as the axis. At the same time, the movable support rod 85 will move downwards to the bottom of the groove inside the fixed block 81. At this time, the telescopic spring 86 will be compressed to the maximum extent, and the rotating locking block 88 will be fully opened and locked into the limiting slot 84, thus limiting the position of the connecting sleeve 82 and stopping the support platform 3 from falling. This provides an emergency stop and prevents the vehicle from falling with the support platform 3, thus providing a safety function. The telescopic spring 86 can convert most of the impact force during the fall into elastic potential energy and store it to reduce the impact on the vehicle, further improving the protection.
