Abstract

Disclosed is an anti-reverse rotation device of a power-driven shoe device, the power-driven shoe device comprising a shoe sole ( 1 ), wherein a group of front wheels ( 2 ) and a group of rear wheels ( 3 ) are arranged on a lower side surface of the shoe sole ( 1 ); and the front wheels ( 2 ) are connected to an anti-reverse rotation mechanism for preventing the front wheels ( 2 ) from rotating in reverse. The anti-reverse rotation mechanism can prevent the front wheels ( 2 ) from rotating in reverse, and as such, when the front wheels ( 2 ) are independently in contact with the ground and a certain included angle is formed between a shoe body and the ground, the situation of the front wheels ( 2 ) applying a certain pressure to the ground and the front wheels ( 2 ) rotating in reverse, such that a lifted foot moves backwards, thereby causing a person to fall down, is avoided, and walking safety is improved.

Claims (6)

1. A power shoe device comprising:

a shoe sole comprising a shoe heel part and a shoe forefoot part, wherein a group of front wheels is mounted on the shoe forefoot part, wherein a group of rear wheels is mounted on the shoe heel part, and wherein the group of front wheels and the group of rear wheels are each disposed on the lower side surface of the shoe sole;

wherein the shoe heel part and the shoe forefoot part are in rotatable connection with each other; and

wherein the group of front wheels are connected with an anti-reverse rotation mechanism comprising a rotating shaft connected with the group of front wheels, a ratchet wheel fixed on the rotating shaft, and a pawl matched with the ratchet wheel for preventing the group of front wheels from being inverted.

2. The power shoe device according to claim 1 , further comprising a group of middle wheels, a motor, and a transmission device, wherein the motor is further disposed at the lower part of the shoe sole; and wherein the output end of the motor is connected with the transmission device which is in driving connection with at least one of the group of middle wheels and the group of rear wheels.

3. The power shoe device according to claim 1 , further comprising a group of middle wheels, a motor, and a transmission device, characterized in that the motor is further disposed at the lower part of the shoe sole; and wherein the output end of the motor is connected with the transmission device which is simultaneously in driving connection with the group of middle wheels and the group of rear wheels.
