Sixth, the gravity-assisted self-propelled shoe has the working principle that:

1. the gravity-assisted self-propelled shoes have the general working principle: the utility model discloses gravity-assisted self-propelled shoes is one kind and utilizes human self weight, turns into human weight kinetic energy, through gravity-assisted self-propelled shoes of gravity booster (gravity booster) drive shoes walking. The utility model provides a gravity-assisted self-propelled shoes lifts the foot action through the nature of human body when walking, utilizes human weight to apply on shoes, turns into wheel (drive wheel) on the kinetic energy drive sole through installing gravity booster (gravity booster) on shoes and rotates and realize walking. The gravity-assisted self-propelled shoes realize braking through the brake blocks arranged behind and below the large-mass inertia flywheel of the gravity-assisted self-propelled shoes. The gravity-assisted self-propelled shoe realizes the retraction control of the rear wheel and the front wheel through a rear wheel retraction control rod arranged on a rectangular base of the gravity booster and a front wheel retraction control rod arranged on a U-shaped base of the front wheel of the gravity-assisted self-propelled shoe. Note: theoretically, the weight of the human body is in direct proportion to the kinetic energy generated by the gravity-assisted device (gravity booster) of the gravity-assisted self-propelled shoe, namely, the larger the weight of the human body is, the larger the kinetic energy generated by the gravity-assisted device (gravity booster) of the gravity-assisted self-propelled shoe is. In practical application, the larger the weight of the human body is, the larger the friction resistance of the gravity booster, the wheel shaft and the tire of the gravity-assisted self-propelled shoe is, and the smaller the weight of the human body is, the smaller the friction resistance of the gravity booster, the wheel shaft and the tire of the gravity-assisted self-propelled shoe is, so that the power-assisted effect obtained after the gravity-assisted self-propelled shoe is worn is basically the same no matter the weight of the human body is large or small. If the weight of the gravity-assisted self-propelled shoes is ignored, the walking is easy and labor-saving just like walking with common shoes when the gravity-assisted self-propelled shoes are worn, but the walking speed is much higher than that of the common shoes.

2. The gravity-assisted self-propelled shoe has the following specific working principle:

(1) walking of gravity-assisted self-propelled shoes: when the gravity-assisted self-propelled shoe is worn for walking, when a left foot lands and lifts up a right foot, the gravity boosters at two sides of the middle part of the gravity-assisted self-propelled shoe on the right foot rapidly descend under the combined action of the self weight of the gravity booster and a return spring (the gravity booster drives a flywheel and a driven wheel support plate as well as a large mass inertia flywheel and drives a small flywheel and a rear wheel to descend), when the lifted right foot naturally falls down to tread, the rear wheel on the gravity booster of the gravity-assisted self-propelled shoe on the right foot lands, the weight of a human body is applied on the gravity booster through the sole of the gravity-assisted self-propelled shoe, and is applied on a transmission chain at the front side (namely one side of a shoe sole) on the gravity booster through a one-way claw on a rectangular base of the gravity booster, so that the transmission chain on the gravity booster moves along the anticlockwise direction (the, the gravity booster is driven to drive the small flywheel to rotate, and then the large mass inertia flywheel and the rear wheel positioned on the large mass inertia flywheel are driven to rotate, and simultaneously the front wheel of the gravity-assisted self-propelled shoe is driven to rotate, and the gravity-assisted self-propelled shoe is driven to walk forwards. When the sole (heel and sole) of the gravity-assisted self-propelled shoe positioned on the right foot descends to the lowest point position (at the moment, the gravity booster drives the flywheel and the driven wheel supporting plate to ascend to the highest point), the transmission chain on the gravity booster stops rotating, the large-mass inertia flywheel on the gravity booster continues to rotate under the action of inertia, the gravity-assisted self-propelled shoe starts to perform inertial sliding at the moment, and the weight of a human body is converted into the inertial kinetic energy of the large-mass inertia flywheel on the gravity booster at the moment. After the shoe slides for a certain distance, the left foot is lifted to do natural treading action, and the two feet alternately circulate in turn, so that the gravity-assisted self-propelled shoe continuously moves forwards.

Note: in actual use, in order to reduce the frictional resistance generated by landing two feet and increase the weight applied to the gravity booster of the gravity-assisted self-propelled shoes, so as to achieve the best and the maximum power-assisted effect, when one foot naturally falls down to do the stepping action, the other foot needs to be lifted, so that the whole body weight is completely applied to the gravity booster of the gravity-assisted self-propelled shoes on the one foot, and one foot always keeps landing (the left foot and the right foot alternately do the stepping action, but the left foot and the right foot do not land simultaneously) in the whole power-assisted walking process, when the inertial sliding of the gravity-assisted self-propelled shoes on the one foot is about to finish, the gravity-assisted self-propelled shoes naturally fall down to do the stepping action again, and the gravity-assisted self-propelled shoes continuously move in the best and the maximum power-assisted states by means of alternate.

<2> the effect of the large mass inertia flywheel on the gravity booster is: the weight of a human body is converted into the rotation kinetic energy of a large-mass inertia flywheel on the gravity booster to be stored, so that the rotation kinetic energy is converted into the inertia kinetic energy, and after the treading action of the gravity-assisted self-propelled shoes is completed (the transmission chain of the gravity booster stops rotating), the gravity-assisted self-propelled shoes continue to slide under the inertia effect of the large-mass inertia flywheel.

<3> gravity booster drives the function of the small flywheel: the rotary force generated by the gravity booster is transmitted to the large-mass inertia flywheel, after the treading action of the gravity-assisted self-walking shoe is completed (the transmission chain stops rotating), the gravity booster drives the flywheel core part of the small flywheel to continue to slide in the rotary direction of the large-mass inertia flywheel under the driving of the large-mass inertia flywheel, namely, the gravity booster drives the small flywheel to only transmit the rotary force (driving force) to the large-mass inertia flywheel without hindering the inertial rotation of the large-mass inertia flywheel.

<4> action of the one-way jack catch of the gravity booster: the one-way jack catch is installed in the front side (the shoe heel one side promptly) of gravity booster transmission chain, and the one-way function of passing through the one-way jack catch makes the transmission chain remove along anticlockwise (the opposite side is clockwise, the direction of advance of shoes promptly) to drive gravity-assisted self-propelled shoes and go forward, and can also prevent gravity-assisted self-propelled shoes from reversing, also can prevent gravity-assisted self-propelled shoes from backing and swift current slope when wearing gravity-assisted self-propelled shoes to go up a slope.

(2) Braking of gravity-assisted self-propelled shoes: the gravity-assisted self-propelled shoe is braked by a brake which is formed by a rubber brake block arranged at the rear lower part of a large-mass inertia flywheel of a gravity booster and telescopic supporting rods of rear wheel brake blocks positioned at two ends of the brake block, the gravity-assisted self-propelled shoe is backwards tilted when braking is needed, the rear lower end of the brake block is contacted with the ground, meanwhile, the brake block moves towards the inclined upper part due to the downward pressing of the brake block, the telescopic supporting rods at two ends of the brake block contract (return springs on the telescopic supporting rods are compressed), the arc-shaped front end of the brake block is contacted with the circular rear lower end of the large-mass inertia flywheel to generate friction braking force, and the braking of the gravity-assisted self-propelled shoe is completed under the combined action of the friction resistance. When the gravity-assisted self-propelled shoe is not needed to be braked, the gravity-assisted self-propelled shoe is tilted forwards, so that the rear lower end of the brake block is not contacted with the ground, the rear wheel brake block telescopic supporting rods at the two ends of the brake block return under the action of the return springs, the brake block is separated from the contact with the large-mass inertia flywheel, and the gravity-assisted self-propelled shoe is braked.

(3) Retraction and extension of front and rear wheels of the gravity-assisted self-propelled shoe: <1> retraction of front wheels of gravity-assisted self-propelled shoes: when the front wheel retraction control rod of the gravity-assisted self-propelled shoe is placed at the upper end position of the support bearing gasket retracted by the front wheel of the gravity-assisted self-propelled shoe, the front wheel of the gravity-assisted self-propelled shoe is in a laid-down state, and the gravity-assisted self-propelled shoe is in a wheel walking state at the moment: i.e. the state of the wheels. When the front wheel retraction control rod of the gravity-assisted self-propelled shoe is placed in the lower end position of the retraction support bearing gasket of the front wheel of the gravity-assisted self-propelled shoe, the front wheel of the gravity-assisted self-propelled shoe is in a retracted state, and the gravity-assisted self-propelled shoe is in a heel walking state at the moment: namely the state of walking by the shoe palm and the shoe heel.

<2> retraction and release of the rear wheel of the gravity-assisted self-propelled shoe: when the rear wheel of the gravity-assisted self-propelled shoe is placed in the gravity booster driving flywheel of the gravity-assisted self-propelled shoe and the position in the sliding chute is vertically moved by the driven wheel supporting plate, the rear wheel of the gravity-assisted self-propelled shoe is in a put-down state, and the gravity-assisted self-propelled shoe is in a wheel-walking state at the moment: i.e. a wheel walking state. When the gravity-assisted self-propelled shoe rear wheel retraction control rod is arranged in the gravity-assisted self-propelled shoe rear wheel retraction positioning hole of the gravity-assisted self-propelled shoe rear wheel retraction control rod, which drives the flywheel and moves the chute below from the driving wheel supporting plate, the gravity-assisted self-propelled shoe rear wheel is in a retraction state, and at the moment, the gravity-assisted self-propelled shoe is in a heel walking state: namely the walking state of the shoe palm and the shoe heel.

Note: when the front and rear wheels of the gravity-assisted self-propelled shoes are in a retracted state, the gravity-assisted self-propelled shoes are in a non-assisted walking state, and when the front and rear wheels of the gravity-assisted self-propelled shoes are in a laid-down state, the gravity-assisted self-propelled shoes are in a gravity-assisted walking state.

Warm prompt: when the gravity-assisted self-propelled shoes are worn for gravity-assisted walking and sliding, the body is required to be inclined forwards to enable the gravity center of the body to move forwards, the gravity-assisted self-propelled shoes are particularly important when the gravity-assisted self-propelled shoes are used on an upslope, the front wheels and the rear wheels are preferably simultaneously grounded when the gravity-assisted self-propelled shoes are worn for heel walking, namely non-assisted walking (used as common shoes), the front wheels and the rear wheels of the gravity-assisted self-propelled shoes are simultaneously folded and locked, the front wheels or the rear wheels are not required to be folded, and the foot lifting amplitude is reduced when the road conditions are poor, and the walking is carried.

The beneficial effects of the utility model are that, the utility model discloses the gravity-assisted self shoes of releasing are the weight of utilizing human self, turn into kinetic energy with the weight of human body, through the gravity-assisted self shoes of gravity booster (gravity booster) drive shoes walking. The utility model provides a gravity-assisted self-propelled shoes lifts the foot action through the nature of human body when walking, utilizes human weight to apply on shoes, turns into wheel (drive wheel) on the kinetic energy drive sole through installing gravity booster (gravity booster) on shoes and rotates and realize walking.
