[0023] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings. Example

[0024] This embodiment provides a new energy vehicle charging pile, including a base 1 constituting a parking space, a charging pile 2 is installed on the right side of the base 1, and the vehicle enters from the left side, wherein a speed bump 3 is provided in the middle of the base 1, a pit is provided on the right side of the speed bump 3, and a mounting box 4 with an opening facing upward is provided in the pit; the distance between the speed bump 3 and the left side of the pit is about 40 to 80 centimeters, which is generally less than the diameter of a wheel, thereby saving space. After the vehicle enters the parking space, the rear wheel just passes over the speed bump 3, and then it can drive to the top of the mounting box 4.

[0025] The installation box 4 is composed of two parts, the left side is the wheel box 5, and the right side is the support plate 9; the left end of the support plate 9 is hinged on the installation box 4, the right end of the support plate 9 can swing, and the right end of the support plate 9 can be placed in a slope shape after being lowered. A plurality of movable pins 10 are arranged below the support plate 9, and a plurality of positioning holes 11 corresponding to the movable pins 10 are arranged on the inner wall of the installation box 4; after the support plate 9 is horizontal, the movable pins 10 are placed in the positioning holes 11 to achieve the support plate 9 to remain horizontal, so that the entire surface of the base 1 remains flush, which is convenient for people to walk.

[0026] There are multiple fixed guide rods 13 at the bottom of the installation box 4. The guide rods 13 pass through the wheel box 5 so that the wheel box 5 can move up and down. The guide rods 13 are covered with compression springs 14 to realize the automatic upward reset of the wheel box 5. At the same time, there is a limit sleeve 15 outside each compression spring 14; when the wheel box 5 is lowered, the limit sleeve 15 can support the wheel box 5 to prevent the compression spring 14 from being crushed. Two large rollers 8 are arranged on the top of the wheel box 5. The large rollers 8 are higher than the base 1 by a certain distance. After the rear wheel reaches the top of the wheel box 5, it can press on the large rollers 8. If the vehicle has a large backward inertia, the rear wheel can travel between the two large rollers 8. Thereby, the two large rollers 8 can lift the rear wheel to realize the idling of the rear wheel.

[0027] A reel 6 is installed inside the wheel box 5, and a carpet 7 is wound on the reel 6, and the carpet 7 is laid on the base 1. The front and rear ends of the reel 6 extend out of the wheel box 5, and a friction wheel 16 is installed; at the same time, a vertical groove 17 is provided on the front and rear inner walls of the installation box 4 to match the friction wheel 16. The upper end of the vertical groove 17 is narrow, so after the wheel box 5 is reset upward, the friction wheel 16 is in close contact with the side wall of the vertical groove 17, causing the friction wheel 16 to be unable to rotate, that is, the carpet 7 will not roll at will. It is convenient for vehicles to drive in and out.

[0028] A rope 19 is connected to the left end of the movable pin 10 on the side wall of the wheel box 5. When the wheel presses the wheel box 5 and the wheel box 5 descends, the movable pin 10 can be pulled out of the positioning hole 11 through the rope 19; then the support plate 9 can be unlocked and rotated. The right end of the support plate 9 can descend under its own weight, opening the depression on the right side and forming a slope. In some embodiments, anti-collision bars 21 are provided on the front and rear sides of the base 1 to guide and protect the vehicle, prevent the vehicle from parking crookedly, and prevent the vehicle from driving diagonally into the parking space from colliding with the charging pile 2.

[0029] The upper right corner of the installation box 4 is equipped with a small roller 12. After the vehicle rear wheel is trapped in the installation box 4 right sides, the rear wheel can be released with the small roller 12 to prevent the vehicle from rushing out and to prevent the wheel from directly rubbing against the installation box 4.

[0030] In some embodiments, an arc plate 18 is installed between the left and right rollers, and the front and rear ends of the arc plate 18 are fixed to the wheel box 5 by bolts, which ensures the beauty and flatness of the entire base 1 and prevents people from falling into the wheel box 5, while facilitating the operation of the reel 6. The specific use process and working principle of this device are as follows: First, the vehicle backs up into the parking space, and when the rear wheels first touch the speed bump 3, the vehicle can be parked and charged. At the same time, the speed bump 3 can give the driver a certain driving quality feedback, prompting the driver that the vehicle has arrived at the position.

[0031] When the vehicle passes over the speed bump 3, it can also be parked at this time, which is also the best charging position. Since the speed bump 3 is passed, the feedback is stronger and the driver can park immediately.

[0032] If the driver is distracted, or the vehicle is operated improperly or the speed is too fast, etc., and the vehicle continues to move backward, the rear wheel of the vehicle will move above the installation box 4. Since the wheel box 5 can move up and down, and the large roller 8 can rotate, when the rear wheel contacts the large roller 8 on the left side, the large roller 8 can form a small rolling obstacle, causing the rear wheel to leave the ground and spin, and then be unable to move backward. At the same time, during this process, since the wheel box 5 is squeezed and moves downward, the friction wheels 16 at the front and rear ends of the reel 6 are no longer contacted by the side walls of the vertical groove 17. The reel 6 can be unlocked, and for front-wheel drive vehicles or four-wheel drive vehicles, the front wheels will rotate, and then drive the carpet 7 to move to the left, so that the vehicle will no longer move backward. The front and rear wheels can slip at the same time.

[0033] In the above state, if the vehicle's inertia to the right is still large enough, the rear wheel can be completely placed between the two large rollers 8, achieving complete idling of the rear wheel and idling of the driving carpet 7 of the front wheel. The wheels are rotating, but the vehicle is slipping and does not want to move backward. In this process, the driver can be given enough feedback and enough time to operate the vehicle; even if it is an automatic driving vehicle, it can detect slipping and exit the automatic driving or give a reminder.

[0034] The design of the speed bump 3 and wheel box 5 at the front is mainly to provide greater driving feedback, so as to prompt the driver to brake immediately, and to give the vehicle a longer sliding time, giving the driver more reaction time, so as to avoid further backward movement and collision with the charging pile 2.

[0035] If the vehicle is moving very fast at the beginning, or the ignition key is pressed too deeply by mistake, the inertia of the vehicle moving backwards is strong. It is very likely to pass over the wheel box 5. At this time, because the wheel box 5 is pressed down, the movable pin 10 under the support plate 9 will be disengaged from the positioning hole 11, and the rear wheel of the vehicle will travel to the position of the support plate 9 and fall into the depression; at this time, the rear wheel is trapped. The direction of travel of the vehicle will also shift downward. The vehicle is forced to stop. Even if the ignition key is not released, the rear wheel will contact the small roller 12 at this time and further idle. In this state of the vehicle, the chassis can be supported by the large roller 8, and the rear wheels are supported by the support plate 9 and the small roller 12; damage to the chassis and rear fenders can be avoided.

[0036] By recessing the rear wheel, the vehicle is forced to stop. If the vehicle needs to get out of trouble, the vehicle can move forward because the support plate 9 is in a slope.

[0037] When the vehicle pulls the carpet 7 or rotates the support plate 9, the support plate 9 can be manually lifted up again, and the arc plate 18 can be manually opened to rotate the reel 6 again so that the carpet 7 is rewound on the reel 6. The whole device can then be restored to normal without causing damage to the device.

[0038] The wheel box 5 is cleverly designed in the device. By pressing down the wheel box 5, the support plate 9 can be unlocked, thereby improving the conditions for the subsequent wheels to be forced into the vehicle. At the same time, pressing down the wheel box 5 can also unlock the reel 6, so that when the front wheel rotates, only the carpet 7 is driven to move, and the vehicle will not actually move.

[0039] In this device, the rear wheel is supported by the wheel box 5 to achieve idling; at the same time, the front wheel is idling through the carpet 7. It can adapt to vehicles of different lengths to achieve sliding. In addition, whether it is a front-wheel drive, rear-wheel drive, or four-wheel drive vehicle, it can achieve the effect and avoid collision.
