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.

Two positioning hooks 20 (only one may be arranged at the middle part of the rear end of the pedal plate 3) for limiting the downward swinging range of the rear end of the pedal plate 3 are transversely arranged between the rear beam 1-3 and the rear end of the pedal plate 3 side by side; the upper end of each positioning hook 20 is hinged with the rear beam 1-3 through a pair of small sliding bearings 1-3-1 which are transversely arranged side by side; a compression spring 21 is connected between the positioning hook 20 and the rear beam 1-3; the force of the compression spring 21 tends to make the front side of the positioning hook 20 close to the rear edge of the footboard 3; thus, when the rear end of the footboard 3 swings downward to touch the upper surface 20-1 of the positioning hook part, the positioning hook 20 hook part will prevent the rear end of the footboard 3 from continuing to swing downward; the upper surface 20-1 of the positioning hook part is an inclined surface with proper inclination, when a pressure exceeding a predetermined value acts on the upper surface 20-1 of the positioning hook part through the rear end of the footboard 3, the lower end of the positioning hook 20 swings backwards against the compression spring 21, so that the rear end of the footboard 3 slides downwards along the upper surface 20-1 of the positioning hook part to be separated from the upper surface 20-1 of the positioning hook part, and the rear end of the footboard 3 can swing downwards all the way to enable the bottom of the wear-resisting piece 18 of the footboard to touch the ground so as to decelerate or brake; therefore, in normal traveling, when a pressure smaller than a predetermined value acts on the rear end of the footboard 3 through the heel part, under the combined action of the compression spring 21 and the positioning hook 20, the rear end of the footboard 3 can be positioned at the hook part of the positioning hook 20 to provide a stable supporting point for the heel part, so that body balance can be kept in sliding, and sliding safety is improved; if deceleration or braking is needed, the weight is intensively acted on the heel part, so that when the pressure applied to the rear end of the pedal 3 by the heel part exceeds a preset value, the rear end of the pedal 3 slides downwards along the upper surface 20-1 of the hook part of the positioning hook against the compression spring 21 until the rear end is separated from the upper surface 20-1 of the hook part of the positioning hook, and then swings downwards until the bottom of the wear-resisting plate 18 of the pedal contacts the ground, so that the aim of deceleration or braking is fulfilled; when the pressure applied to the rear end of the pedal plate 3 disappears or is extremely small, the rear end of the pedal plate 3 rebounds upward under the pulling force applied to the front end of the pedal plate 3 by the extension spring 19.

Two small extension springs 22 which are arranged in bilateral symmetry are connected between the movable support 2-1 of the rear pulley 2 and the rear ends of the two longitudinal beams 1-1, and when the rear pulley 2 slides straight ahead, the acting forces exerted on the movable support 2-1 by the two small extension springs 22 are equal in magnitude and opposite in direction, so that the rear pulley 2 tends to slide straight ahead when not subjected to the action of torsion.
