Description
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 riding 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 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 specific situations and cannot be used for transportation. My patent application, entitled original ecological walking-driven self-propelled shoes for transportation on 7/23.2021, filed a patent application with application number PCT/CN2021/108104, which comprises a frame 1, a front pulley 5 hinged to the front end of the frame 1, and a rear pulley 2 hinged to the rear end of the frame 1, and is characterized in that: the rear pulley 2 adopts a universal wheel which can adjust the direction according to the swing of the heel part; a swing arm 4 is hinged to the front end of the bracket 1 through a swing arm shaft 3 which is transversely arranged; the swing arm 4 is composed of an outer arm 4-1 and an inner arm 4-2 which are respectively positioned at two sides of the bracket 1, and a cross beam 4-3 which is connected between the outer arm 4-1 and the front end of the inner arm 4-2 and connects and fixes the outer arm 4-1 and the inner arm 4-2 into a whole, wherein, the outer arm 4-1 is arranged at the outer side of the foot, and the inner arm 4-2 is arranged at the inner side of the foot; a limiting piece which enables the free end of the swing arm 4 to swing only within a limited angle range is arranged between the swing arm 4 and the bracket 1; the swing arm 4 swings in the angle range limited by the limiting piece, and the free end of the swing arm points to the rear generally; a front pulley 5 is hinged at the end part of the free end of the inner arm 4-2 through a pair of driven wheel bearings 10 and a driven shaft 8, and the front pulley 5 hinged at the free end of the inner arm 4-2 is set as a driven wheel 5-2; a pair of driving wheel bearing sleeves 4-5 which are axially vertical to the length direction of the outer arm 4-1 are arranged at the end part of the free end of the outer arm 4-1; a pair of driving wheel bearings 9 are arranged in the driving wheel bearing sleeves 4-5; a driving shaft 10 is installed in the driving wheel bearing 9, and the driving shaft 10 is coaxial with the driven shaft 8; a front pulley 5 is fixedly connected to the driving shaft 10, and the front pulley 5 fixedly connected to the driving shaft 10 is set as a driving wheel 5-1; a transmission mechanism which utilizes the swing of the free end of the swing arm 4 relative to the bracket 1 within a limited angle range to drive the driving wheel 5-1 to rotate and takes the gravity of the human body as the driving force is arranged between the outer arm 4-1 and the bracket 1; the free end of the swing arm 4, the driving wheel 5-1 and the driven wheel 5-2 can swing up and down on two sides of the bracket 1; therefore, the lowest ground clearance of the bottom of the bracket 1 can be reduced to an ideal value, and the sliding safety and comfort are greatly improved; and, the minimum vertical distance (i.e. the longitudinal distance between the axial swing of the front pulley 5 and the sole force-receiving central point when the axial swing is closest to the sole force-receiving central point) between the axial swing trajectory of the front pulley 5 in the length direction of the support 1 and the support 1 corresponding to the sole force-receiving central point (for convenience of description, the force-receiving central point of the sole portion will be referred to as the sole force-receiving central point) will be set within a preferred range of 0-5 cm, more preferably, the value can be set to be closer to 0, so that the gravity center of the front pulley 5 is close to the stress central point of the sole of the foot, the attaching degree of the original ecological walking driving type self-propelled shoe for transportation and outgoing of the invention to the foot is increased, and the control of the foot on the original ecological walking driving type self-propelled shoe for transportation and outgoing of the invention is facilitated. The main defects are that 1, the front pulley at the outer side is set as a driving wheel, and the front pulley at the inner side is set as a driven wheel, so that the transmission effect, the coordination and the flexibility are slightly poor; 2. in order to facilitate braking, the rear end of the pedal is always in a floating state, so that the heel part has no fixed acting point, and people can easily fall.
