The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master.

The utility model discloses the designer is not enough in a great deal of aspect of AGV charging to prior art, according to the actual demand under the operation scene, has creatively developed the supporting device associated with automatic charging.

As shown in fig. 1, the matching device comprises an AGV and a charging unit under an operation scene, wherein both sides of the AGV are provided with power taking arms, the charging unit is provided with a charging pile 2 connected through an electric wire and a pair of

electrodes

3a and 3b positioned at both sides of the AGV in the width direction of a channel, and the electrodes are fixedly arranged on an insulating base 6 higher than the ground; AGV and fill and be equipped with mutual inductance sensing component who targets in place between the electric pile, AGV reachs under the position state of charging get electric arm and electrode looks voltage joint and fill electric pile and face the electrode circular telegram, charge, AGV is full of and leaves under the position state of charging get electric arm and electrode separation and fill electric pile and face the electrode outage.

As a preferred embodiment of the present invention, the following shows a detailed structure and a detailed functional description of the above-mentioned power-taking arm and the charging unit. As shown in fig. 1 and 2, the electricity-taking arm at one side of the AGV (taking the right side of the AGV as an example) is composed of a fixing rod 11 pivoted to the AGV body 1 and a metal electricity-taking wheel 12 with one end of the fixing rod attached, the metal electricity-taking wheel 12 is connected to a storage battery (not shown) of the AGV, and a return spring 13 connected to the AGV body 1 is provided at one end of the fixing rod 11 far from the metal electricity-taking wheel 12. Based on the structural design of the electricity taking arm, the fixing rod 11 is vertical and the metal electricity taking wheel 12 hangs under the balanced state of the force applied by the reset spring, and as shown in fig. 2, the fixing rod 11 is inclined under the elastic reset force when the metal electricity taking wheel 12 and the electrode 3b are in a contact rolling state, and the metal electricity taking wheel 12 is firmly pressed on the surface of the electrode under the self weight of the AGV and the force applied by the reset spring.
