Detailed Description

The present invention will be further described with reference to the drawings and examples.

In the embodiment, as shown in fig. 1, 2, 3 and 4, the caster with power comprises a fixed shaft 1, a wheel seat 2 is installed at the lower end of the fixed shaft 1, the wheel seat 2 can rotate around the axis of the fixed shaft 1, a roller 3 is installed on the wheel seat 2, an annular gear 31 is arranged on the roller 3, a motor 4 for driving the annular gear 31 to rotate is installed on the wheel seat 2, a wiring terminal 5 is arranged on the motor 4, and a wiring lug 6 is installed on the wheel seat 2; the terminal 6 has a first state in which it contacts the terminal 5 to connect the motor 4, and a second state in which it is disconnected from the terminal 5 to disconnect the motor 4. The inner gear ring 31 of the embodiment occupies small space, and has higher transmission, and the roller 3 can obtain larger driving force; the motor 4 is switched on and off in a mode that the lug 6 is separated from the lug 5, so that the safety and stability are high.

In the embodiment, as shown in fig. 2, 3, 4, 6 and 7, the wheel seat 2 is provided with an elastic reset key 7 for resetting the wire lug 6. The elastic reset key 7 of the embodiment can effectively separate the wiring lug 6 from the wiring terminal 5.

In the embodiment, as shown in fig. 3 and 4, a power receiving shaft 8 capable of moving along the axial direction is installed inside the fixed shaft 1, the fixed shaft 1 is fixed with the power receiving shaft 8 in the circumferential direction, a sliding sheet 9 is installed below the power receiving shaft 8, and the sliding sheet 9 contacts with the upper end surface of the wiring sheet 6; the electrical slide 9 has a first position in which the tab 6 contacts the terminal 5 when depressed, and a second position in which the tab 6 is disengaged from the terminal 5 when moved up. The structure of the embodiment has good conduction performance, and the motor 4 can still be ensured to be well conducted when the roller 3 changes steering.
