Technical Field

[0001] The invention relates to the technical field related to bicycles, and in particular to a multifunctional pedal structure. Background Art

[0002] At present, bicycles are still the mainstream means of transportation for short trips such as going to work, going to school or doing outdoor sports. Generally, a bicycle is equipped with a support frame at the rear wheel or in the middle of the frame. The support frame is mostly a mechanism of a support rod and a spring. When parking the bicycle, the support rod needs to be lowered to support the bicycle. However, the external support frame of the bicycle will destroy the overall appearance of the bicycle. At the same time, after the support frame is used for a long time, the spring will become loose. When passing through a bumpy road, the support rod may fall down, causing the bicycle to trip, posing a safety hazard. Summary of the invention

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figure 1 In the embodiment shown, a multifunctional pedal structure includes a frame 1, a central axis 2 sleeved with the frame 1, a pedal crank 3 fixedly connected to the central axis 2, a pedal shaft 51 fixedly connected to the pedal crank 3, a movable pedal 5 movably sleeved on the pedal shaft 51, the pedal crank 3 is provided with a linkage mechanism 4 which can be locked with the frame 1 at one end and unlocked with the movable pedal 5 at the other end, the linkage mechanism 4 is connected with a control mechanism 31, the pedal 5 is rotatable, and the pedal surface forms a certain angle with the axis of the pedal shaft 51. A locking groove 10 is provided on the frame 1.

[0026] like Figure 2-4As shown, the linkage mechanism 4 includes a mounting cavity 30, which is an L-shaped cavity structure. One end of the mounting cavity 30 is connected to a crank locking mechanism 40, and the other end is connected to a pedal locking mechanism 6. The crank locking mechanism 40 includes a locking protrusion 41, and a locking rocker 42 is fixedly connected to the locking protrusion 41. The locking rocker 42 is an L-shaped structure. A rocker support 43 is connected to the middle of the locking rocker 42, and an elastic device 44 is connected to the connecting end of the locking protrusion 41 and the locking rocker 42. The mounting cavity 30 is an L-shaped cavity structure, and the inner wall of the mounting cavity 30 is fixedly connected to the rocker support 43. The elastic device 44 is fixedly installed on the inner wall of the mounting cavity 30. Due to the action of the rocker support 43, the locking rocker 42 forms a lever with the locking protrusion 41, and the locking rocker 42 moves upward, pushing the locking protrusion 41 downward, and inserting into the locking groove 10, so as to achieve the locking effect of the pedal crank 3. The pedal locking mechanism 6 includes a connecting rod 61, and a slide groove 62 is symmetrically arranged at one end of the connecting rod 61. The center line of the slide groove 62 and the axis direction of the connecting rod 61 have a certain angle. The angle is formed by the slide groove 62 rotating clockwise around the lower end of the slide groove 62, and the angle formed by the center line of the slide groove 62 and the axis of the connecting rod 61 is less than 90 degrees. An elastic element 64 is arranged at the end of the slide groove 62 of the connecting rod 61, and a swing rod 63 is slidably connected to the slide groove 62. The swing rod 63 is a Z-shaped structure, and a guide rod 631 matching the slide groove 62 is arranged at one end of the swing rod 63, and a block 632 is arranged at the other end. The angle between the slide groove 62 and the connecting rod 61 axially can meet the requirement that when the connecting rod 61 moves downward, the guide rod 631 sliding in the slide groove 62 drives the swing rod 63 to swing, and the swing direction is that the end of the block 632 rotates around the swing rod fixed point toward the pedal shaft 51 to complete the unlocking of the movable pedal 5. A locking switch 310 is arranged in the control mechanism 31. One end of the locking switch 310 is connected to a rotating rod 311, a rotating rod hole 313 is sleeved with the rotating rod 311, and the rotating rod hole 313 is connected to the installation cavity 30, and the other end is connected to a locking slider 312. The locking slider 312 is an elliptical structure, and the locking slider 312 matches the locking rocker 42 and the connecting rod 61. The matching ends of the locking rocker 42 and the locking slider 312 are arc concave surfaces. The rotation of the locking slider 312 can push the locking rocker 42 and the connecting rod 61 to slide. The locking switch 310 can be rotated by rotating the rotating rod 311 to rotate the locking slider 312. The locking slider 312 pushes the locking rocker 42 upward to achieve the locking action of the crank, and the locking slider 312 presses the connecting rod 61 downward to unlock the pedal locking mechanism.

[0027] like Figure 3-6As shown, the movable pedal 5 includes a pedal body 53, a mounting sleeve 54 is provided at the mounting end of the pedal body 53, a limiting protrusion 541 is provided inside the mounting sleeve 54, the limiting protrusion 541 matches with the clamping block 632, and a clearance opening 542 is provided on the limiting protrusion 541 and the wall of the mounting sleeve 54. The pedal body 53 is provided with a pedal shaft hole 531, a clearance groove 532 is provided on the inner wall of the pedal shaft hole 531, and a limiting clamping block 533 is connected inside the clearance groove 532. A limiting hole 52 is provided at one end of the pedal shaft 51, and the limiting hole 52 matches with the limiting clamping block 533. The limit block 533 can be set to be inclined or vertical. The limit block 533 has a certain thickness or is set to a "cross" structure. The limit hole 52 is a groove with a similar contour shape to the limit block 533, and the groove contour is slightly larger than the limit block 533 contour, ensuring that the limit block 533 will not rotate around the pedal shaft 51 after being inserted into the limit hole 52, thereby ensuring the stability of the support. The set yield opening 542 can ensure that the pedal body 53 will not interfere with the pedal shaft 51 when it is tilted.

[0028] When the bicycle needs support when parking, the pedal crank 3 needs to be adjusted to a vertical position, and the rotary rod 311 needs to be rotated so that the locking protrusion 41 in the crank locking mechanism 40 is inserted into the locking groove 10, thereby completing the locking action of the pedal crank 3. At this time, the locking slider 312 presses down the connecting rod 61, drives the swing rod 63 to swing, unlocks the pedal locking mechanism 6, and makes the pedal body 53 of the movable pedal 5 escape, slides the pedal body 53, and makes it parallel to the bottom surface, and inserts the limit block 533 into the limit hole 52 to complete the parking support. When it is necessary to restore the riding kinetic energy of the pedal, it is only necessary to insert the pedal body 53 into the pedal crank 3, rotate the rotary rod 311 in the opposite direction, lock the movable pedal 5, unlock the crank locking mechanism 40, and complete the recovery of the riding state. The pedal can replace the external support frame, making the bicycle beautiful, while avoiding the danger of the support frame tripping the bicycle during riding, and playing a certain role in ensuring safety.
