Description

Self-walking shoes

Technical Field

The invention relates to a shoe, in particular to a self-propelled shoe.

Background

Walking should originally be the most healthy and environment-friendly mode of going out, but with the continuous expansion of urban area, the tool of riding instead of walk such as car, electric motor car, bicycle is selected more. The main reason why the walking is slower and tired than the riding is that the energy loss is too large, the gravity center of the human body has a lifting process every time the bicycle moves forward, potential energy is completely wasted when the gravity center descends, and when the bicycle moves forward and walks in a big step, a single foot is required to bear the weight, so that the bicycle is easy to be tired when the bicycle moves forward in a big step for a long time. Compared with walking, the skating shoes are relatively labor-saving and quick, and have the defects that force needs to be exerted to the lateral rear direction when force is exerted, force is not exerted well when sliding in a curve, safety is poor, and the skating shoes are not suitable for being used as vehicles. The bicycle is a relatively energy-saving and environment-friendly vehicle, but is not light and flexible enough compared with the skating shoes, cannot be carried about, and is inconvenient to transfer to subways and buses.

Detailed Description

Example 1:

as shown in fig. 1 to 14: the sole 1 bottom is fixedly connected with a bottom plate 2, two sides of the bottom plate 2 are provided with bottom plate side edges 2a extending downwards, a front pulley 3 is fixedly arranged on a front wheel shaft 4, the front wheel shaft 4 is hinged at the front end of a front swing arm 6 through two bearings 5, the rear end of the front swing arm 6 is hinged with the bottom plate side edges 2a through a front swing arm shaft 7, a transmission mechanism which adopts the swing of the front swing arm 6 to drive the front wheel shaft 4 and the front pulley 3 is arranged between the front swing arm 6 and the bottom plate 2, the transmission mechanism comprises a pinion 8 fixedly connected on the front wheel shaft 4, a bull gear 9 is arranged behind the pinion 8, the bull gear 9 is meshed with the pinion 8, the bull gear 9 is fixedly arranged on a bull gear central shaft 10, the bull gear central shaft 10 is hinged with the front swing arm 6 through two sliding bearings 11 fixedly connected on the front swing arm 6, a flywheel 12 is additionally arranged on the, a flywheel arm 12f is fixedly connected to the flywheel 12, a vertical rod 13 is arranged slightly behind the flywheel 12, the upper end of the vertical rod 13 is fixedly connected with the bottom plate 2, a small pulley 14 is hinged to the lower end of the vertical rod 13, a return spring 15 for driving the flywheel 12 to idle reversely is connected between the flywheel 12 and the front swing arm 6, the return spring 15 can be a rubber extension spring, and the flywheel arm 12f is tightly attached to the small pulley 14 under the action of the return spring 15; therefore, when the gravity of a human body acts on the front pulley 3 to cause the front end of the front swing arm 6 to swing upwards, the small pulley 14 tightly attached to the flywheel arm 12f prevents the flywheel arm 12f from moving upwards, so that the flywheel arm 12f drives the flywheel 12 to rotate, thereby driving the large gear central shaft 10 and the large gear 9 to rotate, and when the large gear 9 rotates, the meshed small gear 8 is driven to rotate, thereby driving the front wheel shaft 4 and the front pulley 3 to rotate.

In order to prevent the front pulley 3 from slipping, a torsion spring 17 is connected between the front swing arm 6 and the bottom plate 2, the torsion spring 17 is sleeved on a torsion spring shaft 18, the torsion spring shaft 18 is screwed on the side edge 2a of the bottom plate, and the torsion spring 17 applies torsion pointing to the direction away from the bottom plate 2 to the front part of the front swing arm 6. Therefore, the front swing arm 6 can swing upwards only by overcoming the pressure of the torsion spring 17, so that the friction force between the front pulley 3 and the ground is increased, the front pulley 3 is prevented from slipping, and when the user walks forwards, the potential energy stored in the torsion spring 17 can be effectively released to apply upward thrust to the heel part.

The rear pulley 19 is fixedly arranged at two ends of a rear wheel shaft 20, the rear wheel shaft 20 is hinged at the rear end of a rear swing arm 21 through two bearings 5, the front end of the rear swing arm 21 is hinged with the side edge 2a of the bottom plate through a rear swing arm shaft 22, and a compression spring 23 is connected between the rear end of the rear swing arm 21 and the rear end of the bottom plate 2; a brake wheel 24 is fixedly arranged in the middle of the rear wheel shaft 20, a brake rod 25 is fixedly connected to the bottom of the bottom plate 2 corresponding to the brake wheel 24, a brake pad 26 is fixedly connected to the lower end of the brake rod 25, and the lower end face of the brake pad 26 is matched with the circumferential surface of the brake wheel 24; when the rear end of the rear swing arm 21 swings upwards to a preset position against the compression spring 23, the brake wheel 24 touches and presses the brake pad 26, and the brake is automatically applied. The compression spring 23 not only acts as a shock absorber, but also the stored energy is more effectively released during the stride, exerting an upward pushing force on the heel. A wire cord 27 is connected between the front end of the front swing arm 6 and the base plate 2 to limit the downward swing range of the front swing arm 6.

The working principle is as follows: when the gravity center of a human body is transferred to the front sole, the torsion spring 17 bears certain initial pressure to increase the friction force between the front pulley 3 and the ground, then the front end of the bottom plate 2 moves downwards, or the front end of the front swing arm 6 swings upwards relative to the bottom plate 2, at this time, the flywheel arm 12f tightly attached to the small pulley 14 under the action of the reset spring 15 drives the flywheel 12 to rotate (the small pulley 14 rolls along the flywheel arm 12f in the process) because of being blocked by the small pulley 14, the flywheel 12 drives the large gear 9 which rotates coaxially, the large gear 9 drives the engaged small gear 8 to rotate, and the small gear 8 drives the front pulley 3 which rotates coaxially to rotate; meanwhile, the rear foot exerts force in the same way as walking, and the compression spring 23 and the torsion spring 17 release energy to apply upward thrust to the heel when the rear foot exerts force. When the speed is reduced or stopped, the gravity center shifts to a heel, the brake wheel 24 contacts and presses the brake pad 26 against the compression spring 23, and the brake is automatically braked.

Example 2:

as shown in fig. 15 to 20, the embodiment 2 is substantially the same as the embodiment 1, except that in the embodiment 2, flywheel gear teeth 12a arranged on the flywheel 12 are used to replace the flywheel arm 12f and the return spring 15 in the embodiment 1, a sector rack 16 is used to replace the vertical rod 13 and the small pulley 14 thereof in the embodiment 1, the sector rack 16 is arranged at the rear side of the swinging track of the flywheel gear teeth 12a along with the front swing arm 6, the tooth part of the sector rack 16 is engaged with the flywheel gear teeth 12a along with the front swing arm 6, the upper end of the sector rack 16 is fixedly connected to the bottom of the bottom plate 2, therefore, when the front end of the front swing arm 6 swings upwards due to the gravity of the human body acting on the front pulley 3, the sector rack 16 fixedly connected to the bottom of the bottom plate 2 rotates the engaged flywheel 12 to drive the large gear central shaft 10 and the large gear 9 to rotate, the large gear 9 drives the engaged small gear 8 to rotate, thereby driving the front wheel axle 4 and the front pulley 3 to rotate.
