In one embodiment, the fixing frame 10 is provided with a first sensing device 71 and a second sensing device 72, which are used for sensing with the sensing device of the AGV, so that the height position of the charging brush plate of the AGV to be charged is specifically located at the first charging height or the second charging height, and the lifting action of the charging device is further controlled. The sensing device may be an optical communication sensor, an electromagnetic sensor, or an image sensor, for example.
According to the charging device of the embodiment of the present disclosure, as shown in fig. 8 and 9, the first lifting mechanism 20 and the second lifting mechanism 30 are both in the middle of the fixing frame 10 in the original state, and the horizontal movement mechanism 40 is in the return state at this time; when the first sensing device 71 senses that the charging brush plate of the AGV to be charged is located at the first charging height, the power mechanism 60 drives the second lifting mechanism 30 to ascend, the second lifting mechanism 30 drives the first lifting mechanism 20 to ascend through the elastic force of the first elastic part 24, the first lifting mechanism 20 simultaneously drives the horizontal moving mechanism 40 to ascend, when the guide wheel 22 at the top of the first moving mechanism is blocked by the upper stop, the second lifting mechanism 30 compresses the first elastic part 24 at the top (or simultaneously stretches the first elastic part 24 at the bottom), the first lifting mechanism 20 stops moving, and the roller of the second lifting mechanism 30 pushes the horizontal moving mechanism 40 to horizontally extend through the V-shaped outline surface 41; further, under the action of the elastic force of the third elastic part 45, the horizontal moving mechanism 40 pushes the charging brush block 50 to move towards the AGV, and after the charging brush block 50 contacts and abuts against the charging brush plate of the AGV, the horizontal moving mechanism 40 continuously stretches out, so that the third elastic part 45 is compressed until the charging brush block 50 contacts and charges the in-place switch 73, and the charging brush block 50 is judged to contact with the charging brush plate of the AGV in place. When the charging is completed, the power mechanism 60 drives the second lifting mechanism 30 to descend, and the first lifting mechanism 20 is still pressed against the upper stop, the second lifting mechanism 30 descends relative to the first lifting mechanism 20, the rollers release the V-shaped outer contour surface 41, the first lifting mechanism 20 pulls the horizontal moving mechanism 40 to return under the stretching resilience force of the second elastic portion 42, and the second lifting mechanism 30 continues to descend and drives the first lifting mechanism 20 to descend until the first lifting mechanism 20, the second lifting mechanism 30 and the horizontal moving mechanism 40 return to the initial state. When the second sensing device 72 senses that the charging brush block 50 of the AGV to be charged is located at the first charging height, the power mechanism 60 drives the second lifting mechanism 30 to descend, and the working process of the charging device is the same as that of the first charging height.
