Description

Originally ecological walking drive type self-propelled shoes for transportation travel Technical Field
The invention relates to a pair of walking shoes, in particular to a pair of original ecological walking driving type self-walking shoes for transportation travel.
Background
The main current purely manpower-driven transportation travel tool is a bicycle, which is labor-saving and greatly improves the traveling speed. But the force exerting modes of riding and walking are not matched, and a plurality of muscle groups cannot well participate in riding; both hands are needed to participate in controlling the direction and maintaining balance; the bicycle is not as natural and comfortable as walking; in addition, cycling can have some adverse effects on local blood circulation; when riding, the actions of the feet are similar to climbing, but only equivalent to stepping in situ, and sliding and walking speed superposition can not be generated; the bicycle has relatively large weight and volume, and consumes more extra energy; in addition, the energy loss of the bicycle chain wheel transmission system is relatively large. The skating shoes can be used for riding instead of walking on specific occasions, the force applying mode is completely different from walking, the skating shoes need to be pedaled backwards and sideways, the skating shoes slide in a curve, and the safety is poor; when the fast sliding is carried out, the back pedaling speed of the leg is required to be higher than the current sliding speed, and the energy loss is large; when the foot leaves the ground, the gravity of the skating shoe needs to be overcome, and the load of the leg is large; in particular, the braking action of the skate is very unnatural, further greatly affecting the safety of the skate; the damping function is not provided; therefore, skates are generally only suitable for entertainment and fitness in certain situations and cannot be used for transportation. At present, some power-assisted shoes capable of sliding by using the weight of a human body as power have low fit degree with walking, unnatural walking and unrepeatable speed. I filed a patent application with the application number of CN2019112873590, namely a self-propelled shoe in 12, 14 and 2019, which comprises an upper and a sole 1, wherein the bottom of the sole 1 is fixedly connected with a bottom plate 2, the rear end of the bottom plate 2 is provided with a rear pulley 4, and the front end of the bottom plate 2 is provided with a front pulley 5, and the patent application is characterized in that: the front pulley 5 is fixedly arranged on a front wheel shaft 6, the front wheel shaft 6 is hinged to the front end of a front swing arm 8 through a bearing 7, the rear end of the front swing arm 8 is hinged to the bottom plate 2 through a small shaft 21, a torsion spring 9 is connected between the front swing arm 8 and the bottom plate 2, and the front end of the front swing arm swings downwards under the action of the torsion spring 9; further, a drive mechanism for driving the front wheel shaft 6 and the front pulley 5 by a displacement of the front end of the front swing arm 8 with respect to the base plate 2 is provided. The walking-like vehicle adopts a comfortable force-generating mode similar to walking and slides linearly, so that the energy loss is greatly reduced, and the advancing speed is greatly improved. The main defects are that the base plate 1, the front pulley 5 and the rear pulley 4 are arranged below the base plate 2, the height of the base plate 2 from the ground is large, the safety is poor, the fitting degree of the self-propelled shoes and the feet is not high, and the control of the feet on the self-propelled shoes is not facilitated; 2. the rear pulley 4 and the brake system which are connected with the bottom plate 2 through the rear swing arm 16 and the compression spring 17 have complex structures, and particularly the sliding direction can not be flexibly controlled; 3. the sole is fixedly connected on the bottom plate 2, shoes can not be replaced randomly, particularly the fitting property between the shoes and feet is poor, and the shoes with the non-elastic hard soles have the walking feeling.
Technical problem
Therefore, the invention aims to provide an original ecological walking driving type self-propelled shoe for transportation trip, which can be driven to slide in an original ecological walking power generation mode, fully convert a large amount of lost potential energy and kinetic energy in walking into sliding kinetic energy, superpose walking speed and sliding speed, greatly improve advancing speed, reduce impact and abrasion on knee joints, flexibly control sliding direction, reduce ground clearance of the self-propelled shoe, improve safety and comfort, improve the fitting degree of the self-propelled shoe and feet and facilitate the control of the self-propelled shoe by the feet. Another object of the invention is: when the walking shoes are used for taking a step, the foot sole part and the heel part which are advancing forwards respectively show streamline changes along with the advancing of the foot step, the front end and the rear end of the walking shoes can always respectively apply upward reverse thrust to the foot sole part and the heel part, and the walking becomes very relaxed. It is yet another object of the present invention to provide a self-propelled shoe that does not interfere with the fit and comfort of the shoe to the foot and that can be easily and quickly attached and detached from the self-propelled shoe. The invention further aims to ensure that the braking action is very natural and comfortable, and the brake can be effectively and safely performed in time in any traveling state, so that the invention can be suitable for being used as a main transportation travel tool.

Industrial applicability
The working principle is as follows:
when walking: when the body weight acts on the front pulley 5 to cause the free end of the swing arm 4 to swing upwards relative to the bracket 1, the sector-shaped internal gear 1-3-1 drives the meshed driven gear 21 and the intermediate shaft 18 to rotate, so that the flywheel 20 drives the meshed pinion gear 17 and the driving shaft 10 and the driving wheel 5-1 to rotate through the large gear 20-1, and forward power is generated;
when the step is lifted and is stepped forward: under the combined action of the self gravity of the swing arm 4 and the front pulley 5 and the resilience force of the torsion spring 11, the free end of the swing arm 4 swings downwards to be tightly attached to the lower stop block 1-10, in the process, the torsion spring 11 exerts upward counter-thrust on the front end of the bracket 1 and the sole part through the swing arm 4, and meanwhile, under the spring force action of the load-bearing type return spring 16, the rear end of the pedal plate 12 also exerts upward counter-thrust on the heel part;
therefore, when the height from the ground of the sole part and the heel part which step forward is in streamline change along with the stepping of the foot step, the front end of the bracket 1 and the rear end of the pedal plate 12 can always respectively apply upward reverse thrust to the sole part and the heel part, so that the stepping becomes very easy;
in normal running, when the sole and the heel are stressed in a balanced manner or completely under the stress of the sole, the wear-resisting plate 14 does not touch the ground 28 under the spring force of the load-bearing return spring 16;
if the speed reduction or braking is needed, when the weight is intensively acted on the heel part, the rear end of the pedal 12 swings downwards against the bearing type return spring 16 to enable the wear-resisting plate 14 to touch the ground, and the automatic braking is realized, so that the braking action is very natural and comfortable, and the safe braking can be timely and effectively realized in any traveling state.
