[0043] The present invention provides an electric vehicle automatic charging mechanical arm and robot. After the adjustment of the adjustment mechanism 1 is completed, the second infrared distance control module 21 is operated to detect the position of the vehicle charging port and the automatic charging gun head 223. After the detection is completed, it can adjust the operation of the drive motor 203. The drive motor 203 can be rotated through the electric adjustment rod 202, thereby driving the automatic charging gun head 223 to adjust the angle so that the automatic charging gun head 223 is attached to the vehicle charging port for charging operations.

[0044] The first infrared distance control module 13 and the second infrared distance control module 21 proposed in the present invention are a common existing structure, which can be divided into an infrared distance sensor and a controller layer by layer. The infrared distance sensor is a device that uses infrared technology to measure the distance between an object and the sensor. There is an infrared emitter inside the sensor, which emits a beam of infrared light. When this beam of infrared light encounters an object in front, it will be reflected back by the object. The sensor's receiver (usually a photodiode or phototransistor) receives the reflected infrared light. The sensor calculates the distance between the object and the sensor by measuring the time difference between the emission and reception of the infrared light, or by analyzing the change in the intensity of the reflected light. The controller refers to a main command device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit in a predetermined order to control the start, speed regulation, braking and reverse of the motor. In the present invention, the first infrared distance control module 13 and the second infrared distance control module 21 can control the movement of the moving component 11, the first moving component 12, the second moving component 20 and the charging component 22 on the device after detecting the distance between the vehicle and the device, so that the automatic charging gun head 223 reaches the charging port of the electric vehicle for charging. In the following working principle, this part will not be described in detail.

[0045] All electrical devices in the present invention are powered by external power supplies.

[0046] Working principle: Before use, place the device at the designated location, and adjust the position of the fixing pile 102 in the slide 101 according to the installation point reserved on the site. After the adjustment is completed, fix the base 100 through the fixing pile 102. After the fixation is completed, the charging operation can be carried out. When the vehicle is docked, the first infrared distance control module 13 can detect the distance between the device as a whole and the vehicle. When the distance is far, it can control the servo motor 113 to run. After the servo motor 113 is in operation, it drives the two electric screws 111 to run in the same direction through the transmission belt 112, so that the moving plate 114 can move forward at a uniform speed along the guide groove 110. During the forward movement, the auxiliary wheel 115 at the bottom can help the moving plate 114 to be more stable. It moves in a fixed position. After moving to the appropriate position, the overall height of the charging mechanism 2 can be adjusted by the first connecting frame 121 and the second connecting frame 122. After adjusting to a certain position, the charging mechanism 2 is rotated by the electric turntable 124 so that it can adapt to the position of the vehicle's charging port for charging. After the adjustment of the adjustment mechanism 1 is completed, the second infrared distance control module 21 is operated to detect the position of the vehicle's charging port and the automatic charging gun head 223. After the detection is completed, it can adjust the operation of the drive motor 203. The drive motor 203 can be rotated through the electric adjustment rod 202, thereby driving the automatic charging gun head 223 to adjust the angle, so that the automatic charging gun head 223 fits the vehicle's charging port for charging.

[0047] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
