Abstract
A foot brake structure for a mobility device includes: a footboard having an upper surface extending in a plane direction and having a rear wheel at a rear thereof; and a friction plate positioned above the rear wheel, having a portion extending forward of the rear wheel and rotatably assembled to a rear end of the footboard by a rotating shaft, and having a lower surface brought into contact with or spaced apart from a surface of the rear wheel depending on whether or not the friction plate is rotated around the rotating shaft, wherein when the friction plate is rotated around the rotating shaft by an external force, the lower surface of the friction plate is brought into contact with the surface of the rear wheel, thereby applying a braking force to the rear wheel.

A foot brake structure for a mobility device, comprising:
- a footboard having an upper surface extending in a plane direction and having a rear wheel at a rear thereof;
- a friction plate positioned above the rear wheel, having a portion extending forward of the rear wheel and rotatably assembled to a rear end of the footboard by a rotating shaft, and having a lower surface brought into contact with or spaced apart from a surface of the rear wheel depending on whether or not the friction plate is rotated around the rotating shaft;
- a magnetic body positioned at the portion of the friction plate and generating magnetic force between the footboard and the magnetic body so that the friction plate is rotated around the rotating shaft in a direction in which the friction plate is spaced apart from the surface of the rear wheel;
- and
- a magnetic field sensor positioned at the rear end of the footboard and sensing a change in a magnetic field of the magnetic body as the friction plate is rotated around the rotating shaft,
- wherein when the friction plate is rotated around the rotating shaft by an external force, the lower surface of the friction plate is brought into contact with the surface of the rear wheel, thereby applying a braking force to the rear wheel, and
- an action point at which the friction plate applies the braking force to the rear wheel is closer to the rotating shaft of the friction plate than a press point at which the external force is applied so as to amplify the braking force.
