Abstract

An adjustment mechanism for an electric power-driven shoe, the mechanism comprising a shoe sole ( 1 ) is presented, wherein a plurality of rolling wheels ( 2 ) are arranged below the shoe sole ( 1 ); a foot-positioning mechanism is arranged above the shoe sole ( 1 ) and is provided with an angle-adjusting mechanism for adjusting an angle between the foot-positioning mechanism and a lengthwise direction of the shoe sole ( 1 ).

Claims (17)

1. An adjustment mechanism for electric power shoes, the mechanism comprising:

a shoe sole, wherein the shoe sole comprises a shoe heel part and a shoe forefront part, wherein the shoe heel part and the shoe forefoot part are rotatably hinged together;

a plurality of rollers disposed below the shoe sole; and

a foot locating mechanism, comprising a base plate, disposed above the shoe heel part, wherein the foot locating mechanism comprises an angle adjustment mechanism configured to adjust an angle between the foot locating mechanism and the shoe sole along a lengthwise direction, and wherein the base plate is configured to accommodate a heel of a wearer.

2. The adjustment mechanism of claim 1 , wherein the foot locating mechanism further comprises a shoe heel locating member disposed at a rear part of the shoe sole,

wherein the base plate is connected to block pieces extending upwards from two sides and a rear side of the base plate, and

wherein the block pieces are configured to form a space for accommodating the heel of a wearer.

3. The adjustment mechanism of claim 1 , wherein the base plate comprises at least two slot holes formed in the base plate.

4. The adjustment mechanism of claim 3 , wherein each of the at least two slot holes are configured to receive a fastener to attach the foot locating mechanism to the shoe sole.

5. The adjustment mechanism of claim 3 , wherein the at least two slot holes comprise a first group of slot holes and a second group of slot holes,

wherein the first group of slot holes and the second group of slot holes are disposed crosswise in the base plate,

wherein slot holes within each of the first group and the second group are parallel with respect to other slot holes in the respective group, and

wherein slot holes in the first group of slot holes are nonparallel with respect to slot holes in the second group of slot holes.

6. The adjustment mechanism of claim 1 , wherein the plurality of rollers comprise six rollers, and wherein four rollers of the plurality rollers are disposed on the shoe heel part and two rollers of the plurality of rollers are disposed on the shoe forefoot part.

7. The adjustment mechanism of claim 1 , further comprising a motor disposed at a lower part of the shoe sole, wherein the motor is connected with a transmission device in driving connection with at least one of a plurality of rollers.

8. The adjustment mechanism of claim 7 , wherein the shoe heel part and the shoe forefoot part are hinged together.
