Abstract

A parkour wheeled boot for increasing moving speed, having self-balancing function, wearable on a respective leg of a user. Each boot has a wearing mechanism, a shock reduction mechanism, a drive mechanism, a motion transmission mechanism, a power mechanism and a control mechanism. The wearable mechanism has a pedal, a pedal fixation rack, calf supporting plates, and magnetic pieces or belt and buckle. The shock reduction mechanism has a spring seat, springs and a cover. The drive mechanism has a motor having a hollowed center, and also an inner wall of a bearing. The motion transmission mechanism has an outer wall of the bearing, a wheel hub, and a rubber tire. The power mechanism has batteries, battery smart protection control board, ports and connection wires. The control mechanism is a single board unit with microprocessor, angular speed sensor, acceleration sensor, pressure sensor and relevant electronic components.

Claims

1. A parkour wheeled boot for increasing moving speed, each being worn at an outer side of a respective leg of a user;

the boot on a left leg of the user is symmetrical to the boot on a right leg of the user;

each boot comprises a wearing mechanism (21), a shock reduction mechanism (22), a drive mechanism (23), a motion transmission mechanism (24), a power mechanism (25) and a control mechanism (26);

wherein the wearing mechanism (21) comprises a pedal (3), a pedal fixation rack (2), an upper calf supporting plate (1a) and a lower calf supporting plate (1b);

the pedal (3) is mounted on the pedal fixation rack (2);

the pedal fixation rack (2) is fixedly connected to a shock reduction spring seat cover (9);

the lower calf supporting plate (1b) is connected with an outer side of a semi-circular shock reduction spring seat (11);

the upper calf supporting plate (1a) and the lower calf supporting plate (1b) are mutually connected through insertion or folding;

the shock reduction mechanism (22) and the wearing mechanism (21) are mutually connected;

the shock reduction mechanism (22) comprises the semi-circular shock reduction spring seat (11), shock reduction springs (10) and the shock reduction spring seat cover (9);

the shock reduction springs (10) are mounted on the semi-circular shock reduction spring seat (11);

the shock reduction springs (10) and the semi-circular shock reduction spring seat (9) are connected via screw bolts;

the semi-circular shock reduction spring seat (11) of the shock reduction mechanism (22) is connected with the drive mechanism (23);

compressibility of each of the shock reduction springs (10) is around 2 cm to ensure better buffering ability of the boot on rough road surfaces;

the drive mechanism (23) comprises a circular electromagnetic motor having a hollowed center or a circular motor having a hollowed center and without an iron core, formed by a first U-shape end cap stator supporter (6a), a second U-shape end cap stator supporter (6b), a super thin bearing having a large diameter bore (13), a stator iron core (12), and an outer rotor of magnetic steel (14);

the stator iron core (12) is provided inside the super thin bearing having a large diameter bore (13), and the outer rotor of magnetic steel (14) is provided external to the stator iron core (12);

the first U-shape end cap stator supporter and the second U-shape end cap stator supporter are parts of the drive mechanism (23) visible from outside;

interior sides of the first and second U-shape end cap stator supporters are tightly fitted with an inner wall of the super thin bearing having a large diameter bore (13), and the first and second U-shape end cap stator supporters are driven by power generated by separation magnetic force from the outer rotor of magnetic steel (14), the stator iron core (12) and windings;

the motion transmission mechanism (24) comprises an outer wall of the super thin bearing having the large diameter bore (13), a wheel hub (5) and a tire (4);

the motion transmission mechanism (24) has a function of transferring the power transmitted from the drive mechanism (23) to rolling motion on the ground surface;

the power mechanism (25) comprises specified type separable modular rechargeable batteries (8) and ports thereof;

the power mechanism (25) supplies power to the entire boot;

specified type is defined as specifying a certain capacity for one independent modular unit;

separable is defined as separable with the boot under weight limitation;

during separable condition of the batteries, power is supplied to the boot through connection wire or wireless means;

each modular unit is capable of quickly assembling with other modular units through hidden fasteners to provide power for continuous use for long distance travel;

the control mechanism (26) is a control board (7) being a single board unit;

the control board (7) is an equipment control center;

the control board (7) not only has relevant components found in a control board of a conventional self-balancing vehicle, including an angular speed sensor and an acceleration sensor, but also has a pressure sensor which controls power output and power cut of the whirling wheel in accordance with alternate movement of the user'"'"'s feet on and off the ground.

2. The parkour wheeled boot for increasing moving speed as claimed in claim 1, wherein the shock reduction mechanism (22), the drive mechanism (23), the motion transmission mechanism (24), the power mechanism (25) and the control mechanism (26) together form a power wheel;

the power wheel is an independent self-balancing power wheel having a weight under 4 kg and a size of 6-20 inches;

each power wheel is fixed to an outer side of a respective leg of the user;

the power wheels on both legs of the user move to advance the body forward in accordance with natural alternate movement of the feet of the user.

3. The parkour wheeled boot for increasing moving speed as claimed in claim 1, wherein when power is shut down or depleted, the boot still provides non-powered assistance in continued travelling because it is designed in accordance with the natural physical development of human beings and operates in accordance with walking traits of human beings.
