Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a schematic diagram of a structure of Embodiment 1 of the present invention.

DETAILED DESCRIPTION OF THE UTILITY MODEL

(2) A further detailed description will be made below to the present invention in combination with accompanying drawings and specific implementation modes.

Embodiment 1

(3) With reference to FIG. 1, power shoe devices are provided, each of which includes a shoe sole 1. A plurality of rotating wheels 2 are disposed below the shoe sole 1, and a motor 3 is further disposed at the lower part of the shoe sole 1; and the output end of the motor 3 is connected with a transmission device which is in driving connection with the rotating wheels 2. Each power shoe device is characterized in that rotating wheel racks 6 for mounting the rotating wheels 2 are disposed on two sides of the lower side surface of the shoe sole 1. The transmission device includes a driving wheel 4 and multi-stage speed reduction structures which are disposed on the rotating wheel racks 6 along the lengthwise direction of the shoe sole 1. The transmission device further includes a planetary speed reducer which is connected with the motor 3.

(4) The rotating wheel racks 6 for mounting the rotating wheels 2 are disposed on the two sides of the lower side surface of the shoe sole 1. Speed reduction gear sets 5 are all mounted on the inner side surfaces of the rotating wheel racks 6, and gears in the speed reduction gear sets 5 are located on the same straight line.

(5) The rotating wheels 2 at least include a first rotating wheel group 21 and a second rotating wheel group 22. The driving wheel 4 is located in the middle of a space between the first rotating wheel group 21 and the second rotating wheel group 22. The speed reduction gear sets 5 are symmetrically disposed on two sides of the driving wheel 4, so that the transmission device simultaneously drives the first rotating wheel group 21 and the second rotating wheel group 22.

(6) The shoe sole 1 consists of a shoe heel part 11 and a shoe forefoot part 12. The shoe heel part 11 and the shoe forefoot part 12 are in rotatable connection with each other.
