[0002] At present, with the rapid development of the automobile industry, new energy electric vehicles are gradually being widely promoted and popularized; but new energy electric vehicles need to be charged during use. In the existing technology, there are many ways for charging equipment to charge vehicles: one is to use electric convenient charging equipment, which is equipped with a charging cable, and the vehicle is charged by the charging cable in conjunction with a suitable socket and an on-board charger. Another type of household charging pile or fast charging pile charges the vehicle by placing the charging head in the charging pile into the corresponding charging socket of the vehicle. However, the charging methods of the above-mentioned charging equipment all require manual operation to charge the vehicle, and the operation process is cumbersome and the convenience is poor. Summary of the invention

The purpose of the present invention is to design an adaptive charging bow, which can be used to charge vehicles more quickly and avoid the tedious manual operation; the adaptive charging bow can effectively maintain the charging contact area between the charging plate and the receiving plate.

[0004] In order to solve the above technical problems, specifically, the technical solution of the present invention is as follows:

[0005] An adaptive charging bow comprises a charging plate (500), a front-rear adjustment mechanism (200) fixedly connected to the charging plate, a parallelogram mechanism (300) fixedly connected above the front-rear adjustment mechanism, a left-right adjustment mechanism (400) connected above the parallelogram mechanism, and a device frame (100) located above the left-right adjustment mechanism for fixing the left-right adjustment mechanism.

The charging docking structure is simpler, and the vehicle can be charged quickly. In terms of charging operation performance, the cumbersome manual operation is eliminated.

[0006] The front-to-back adjustment mechanism (200) is composed of a front-to-back adjustment mechanism movable part (202) fixedly connected to the charging electrode plate (500), and a front-to-back adjustment mechanism fixed part (201) rotatably connected to the front-to-back adjustment mechanism movable part, so as to realize the self-adaptation of the self-adaptive charging bow to the front-to-back direction;

[0017] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] The working mode of the adaptive charging bow is as follows:

[0019] When the charging device receives a charging signal, the charging signal is sent to the control system, and the control system issues a command to cause the device frame (100) to push the charging bow downward to contact the pantograph (800) of the charging vehicle. When the charging bow plate (500) contacts the pantograph plate (800), the pressure sensor (600) installed on the parallelogram mechanism connecting rod (301) detects the contact pressure. If the set pressure value has not been reached, the device frame (100) pushes the charging bow to continue to press downward, and the parallelogram mechanism connecting rod (302) will continue to tilt at a smaller angle until the contact pressure values ​​of the four charging bows all reach the set value of the pressure sensor (600). At this time, the pressure sensor (600) is installed on the parallelogram mechanism connecting rod (301). The force sensor (600) is in a compressed state, and the device frame (100) stops pressing down; when there is a height difference or inclination in the front-to-back direction of the pantograph plate (500), the charging pantograph plate (500) is subjected to the tension of the pressure sensor (600), resulting in the front-to-back imbalance of the charging pantograph plate (500). At this time, the front-to-back adjustment mechanism movable part (202) and the front-to-back adjustment mechanism fixed part (201) produce a relative rotation movement, and the front-to-back adjustment mechanism movable part (202) drives the charging pantograph plate (500) to rotate, so that the charging pantograph plate (500) and the pantograph plate (800) adjust the effective contact area and reach the optimal charging state, thereby charging (for detailed explanation, refer to Figure 4 ); When the charging bow plate (500) contacts the pantograph plate (800) and there is a height difference, tilt or particle obstacle (900) in the left and right directions, the charging bow plate (500) is subjected to the tension of the pressure sensor (600), resulting in the left and right imbalance of the charging bow plate (500). At this time, the movable part (401) of the left and right adjustment mechanism and the fixed part (402) of the left and right adjustment mechanism produce a relative rotation action, combined with the parallelogram mechanism (300) to produce a left and right translation action. This composite action can move the clean particle obstacle (900) left and right and adjust the effective contact area of ​​the charging bow plate (500) and the pantograph plate (800) to achieve the best charging state, thereby charging (for detailed explanation, refer to Figure 5 , 6 ).

[0020] When the charging device receives a power-off signal, the power-off signal is sent to the control system, and the control system issues a command to cause the device frame to pull the charging bow upward and retract it. At this time, the front and rear adjustment mechanism active parts (202) are subject to the elastic force of the spring sheet, forcing the front and rear adjustment mechanism active parts to drive the charging plates back to their original positions to maintain balance; similarly, the left and right adjustment mechanism active parts (401) are subject to the elastic force of the compression spring, forcing the left and right adjustment mechanism active parts to drive the parallelogram mechanism frame to return to its original position to maintain balance; similarly, the parallelogram mechanism is subject to the tension of the pressure sensor, forcing the connecting rod (302) to rotate, the frame to translate, the spacing to return to its original state, and the connecting rod inclination angle to increase to the initial position. The spacing is controlled by the original state limit to the original set value,

[0021] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
