Description

Technical Field

[0001] The invention relates to the field of foot pedals, and in particular to an adjustable foot pedal mechanism. Background Art

[0002] Bicycles, also known as bicycles or bikes, are usually small two-wheeled land vehicles. After riding on the bicycle, people use pedals as power, which is a green and environmentally friendly means of transportation. When using a bicycle, people usually use the soles of their feet to push the bicycle forward. However, if the soles of the feet slip off the pedals, the bicycle is likely to roll back when going uphill, which may cause an accident in serious cases. At the same time, if the force applied to the pedals is not enough, the bicycle will also roll back, causing an accident. Summary of the invention

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Embodiment 1:

[0025] like Figure 1-6As shown, an adjustable pedal mechanism includes a pedal shaft 2, which is rotatably connected to a pedal 1. The pedal 1 is a cavity structure with an opening on one side. A button 8 is provided on the treading surface of the pedal 1. A control block 3 is provided in the cavity of the pedal 1. The control block 3 is elastically connected to the button 8. The button 8 is fixedly connected to a control spring 7. The control spring 7 is fixed to the upper surface of the control block 3. The cross section of the button 8 is convex. The button 8 is embedded with the treading surface of the pedal 1. The button 8 can move downward and cannot be separated from the pedal 1 due to the upward limit of the pedal 1. The control block 3 can move up and down. The control block 3 is movably connected to a conveying block 4. The conveying block 4 is movably connected to a baffle 5 that can pop out of the cavity of the pedal 1 and is located at the front end of the treading surface of the pedal 1. The control block 3 is rectangular, one surface is an inclined surface, and the surface perpendicular to the inclined surface is a controlled part 31. There are two controlled parts 31, which are arranged at both ends of the inclined surface. The controlled part 31 is a spherical surface. A fixed block 6 is provided in the cavity of the pedal 1. The fixed block 6 is provided with a raised control part 61. There are two fixed blocks 6, which are symmetrically distributed on both sides of the controlled part 31 of the control block 3 with the central axis of the control block 3 as the symmetry axis. The control part 61 is a spherical groove. The control part 61 is adapted to the controlled part 31. The spherical groove of the control part 61 and the spherical curvature of the controlled part 31 are equal. The controlled part 31 is embedded with the control part 61, and the control block 3 is stuck by the fixed block 6 and cannot move up and down. The cross section of the conveying block 4 is a right-angled trapezoid. The inclined surface of the conveying block 4 is in contact with the inclined surface of the control block 3. The right-angle surface of the conveying block 4 adjacent to the inclined surface is provided with a slide groove 41. The pedal 1 is provided with a slide rail 11 protruding from the inner wall of the cavity. The slide rail 11 is embedded with the slide groove 41. Another right-angle surface of the conveying block 4 is provided with a raised part, and the raised part and the right-angle surface form a baffle bin. The baffle bin is close to the side of the opening of the pedal 1 cavity. The baffle 5 is plate-shaped. The baffle plate 5 is movably connected to the baffle bin of the conveying block 4. A spring bin is provided at the lower part of the baffle plate 5. The spring bin is provided with a baffle spring 53. One end of the baffle spring 53 is fixed to the raised part of the conveying block 4, and the other end is fixed to the spring bin. The surface of the baffle plate 5 close to the right-angle surface of the conveying block 4 is provided with a toe groove 51 with a concave surface. The groove bottom of the toe groove 51 is an arc surface. Prevent the foot from sliding off the pedal 1. A stop bar 12 is provided on the inner surface of the side of the pedal 1. A convex strip 52 is provided on the side of the lower part of the toe groove 51 of the baffle plate 5. The convex strip 52 is adapted to the toe groove 51. When the baffle plate 5 does not pop out of the conveying block 4, the convex strip 52 is not in contact with the stop bar 12. When the baffle plate 5 pops out from the conveying block 4, the convex strip 52 and the stop bar 12 are in close contact, preventing the baffle plate 5 from detaching from the pedal 1, and the baffle plate 5 at the lower part of the toe groove 51 is buckled with the pedal 1.

[0026] Working process: While riding, press button 8 with your toes or the side of your foot. Button 8 compresses control spring 7, and control block 3 moves downward under the action of control spring 7, and controlled part 31 breaks away from the constraint of control part 61. Control block 3 continues to move downward to push conveying block 4 to move toward the opening of pedal 1. The upper part of baffle 5 extends out of the opening of pedal 1, and baffle 5 bounces up under the action of baffle spring 53. The convex strip 52 on the lower side of baffle 5 is blocked by baffle strip 12, and baffle 5 will not tilt with the treading surface of pedal 1, nor can it detach from pedal 1. The toes fall into the toe groove 51, which increases the force-bearing area of ​​pedal 1 and limits the foot from slipping out of pedal 1 due to excessive force and causing an accident. When returning to leisure riding, press the upper end surface of the baffle 5 with your foot to overcome the elastic force of the baffle spring 53, and the baffle 5 converges into the baffle bin of the conveying block 4. The conveying block 4 pushes the control block 3 to move in the direction of the button 8. When the controlled part 31 is embedded in the control part 61, the control block 3 no longer moves up, and the baffle 5 and the conveying block 4 are both converged in the cavity of the pedal 1.
