[0010] This type of rotary adjustable foot pedal features a simple structure, ingenious design, and reasonable layout. Addressing the problems of traditional foot pedals with no adjustable angle, it employs a unique structure. First, the foot pedal is rotatably connected to the base plate, supported and driven by a hydraulic rod. Second, a locking mechanism is located on the bottom of the foot pedal, allowing the user to easily unlock it. Once unlocked, the foot pedal can swing relative to the base plate to change its tilt angle.

[0016] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 5 The illustration shows a rotary lifting foot pedal. The foot pedal device includes a base plate 1, one side of which is hinged to a foot pedal 2. Locking plates 3 are provided at both ends of the base plate 1. A locking mechanism matching the locking plates 3 is provided on the foot pedal 2. A hydraulic rod 4 is also connected to the base plate 1, one end of which is hinged to the base plate 1, and the other end is hinged to the bottom surface of the foot pedal 2. The locking plates 3 are further provided with multiple locking holes 24 distributed at equal arc angles, and each locking hole 24 is equipped with a disengaging mechanism 5.

[0017] The locking mechanism includes a pressure rod 6 movably connected to the foot pedal 2. A pressure head 7 is provided at the top of the pressure rod 6, and a conical head 8 located below the foot pedal 2 is connected to the bottom of the pressure rod 6. The locking mechanism also includes two symmetrically distributed swing rods 9. Rollers 10 are provided at the top of each swing rod 9, and the rollers 10 contact the sidewall of the conical head 8. The bottom of each swing rod 9 is rotatably connected to one end of a locking rod 11. The locking rod 11 is movably connected to a first guide sleeve 13 fixedly mounted on a support plate 12, which is fixedly connected to the foot pedal 2. The outer end of the locking rod 11 matches the stop mechanism 5, and a chamfered portion 14 is also provided at the outer end of the locking rod 11. A fixing member 15 is also provided on the support plate 12, located between the two swing rods 9. A reset mechanism is connected between the fixing member 15 and the swing rods 9.

[0018] The reset mechanism includes a guide rod 25, one end of which is fixedly connected to the fixing member 15. The other end of the guide rod 25 is movably sleeved in a second guide sleeve 26 located on the swing rod 9. A spring 20 is also sleeved outside the guide rod 25, located between the fixing member 15 and the second guide sleeve 26. The end of the locking rod 11 can be inserted into the locking hole 24. To allow the guide rod 25 to move smoothly in the second guide sleeve 26, the inner diameter of the second guide sleeve 26 is larger than the outer diameter of the guide rod 25.

[0019] The dividing mechanism 5 includes an elastic sheet 21. The upper part of the elastic sheet 21 is fixedly connected to the locking plate 3 by a fixing screw, and the lower part of the elastic sheet 21 is rotatably connected to the rotating shaft 22 on the locking plate 3. The end of the rotating shaft 22 is provided with a paddle 23. When the elastic sheet 21 does not deform, the edge of the paddle 23 interferes with the movement trajectory of the end of the locking rod 11.

[0020] The working process of the rotary lifting foot pedal is as follows: in the initial state, under the action of the spring 20, the two locking rods 11 are in the extended state, the end heads of the two locking rods 11 extend into a pair of locking holes 24, under the action of the locking mechanism, the foot pedal 2 is relatively fixed with the bottom plate 1, the user steps on various mechanisms arranged on the foot pedal 2, sends a signal to the control system of the motorcycle, and the motorcycle is controlled to normally operate;

[0021] When the user needs to change the inclination angle of the foot pedal 2, the pressing head 7 is stepped on downward, the pressing rod 6 is driven to move downward relative to the foot pedal 2, the conical head 8 at the bottom end of the pressing rod 6 moves and drives the two rollers 10 on the two sides to move, thereby driving the two swing rods 9 to swing, the bottom end of the swing rod 9 pulls the locking rod 11 to be retracted (the locking rod 11 is movably connected to the long hole in the swing rod 9, so that the locking rod 11 will not be stuck during the above-mentioned operation), the locking rod 11 moves in the first guide sleeve 13, and the end portion of the locking rod 11 is withdrawn from the corresponding locking hole 24, the locking mechanism is unlocked, and the foot pedal 2 restores the degree of freedom,

[0022] If downward adjustment is needed, the user steps on the foot pedal 2 with force, and the foot pedal 2 swings downward, if upward adjustment is needed, the user does not need to exert force, and the foot pedal 2 swings upward under the action of the hydraulic rod 4; during the above-mentioned swinging, the end head of the locking rod 11 slides on the inner wall of the locking plate 3, and moves to the next locking hole 24, is automatically popped out and clamped in the locking hole 24, if the inclination angle corresponding to the locking hole 24 is still not the inclination angle required by the user, the above-mentioned operation is repeated until the foot pedal 2 is adjusted to the appropriate angle and stopped;

[0023] When the locking rod 11 moves to the position matched with the locking hole 24, under the action of the spring 20, the locking rod 11 moves outward, the end portion of the locking rod 11 is inserted into the locking hole 24, the foot pedal 2 is locked, during the movement of the end portion of the locking rod 11, because the end portion of the locking rod 11 is a smooth chamfer portion 14, the push piece 23 is pushed to move, the push piece 23 drives the rotating shaft 22 to rotate by a certain angle, the locking rod 11 is displaced, during the process, the elastic sheet 21 is elastically deformed, and when the push piece 23 is moved by the locking rod 11, the push piece 23 generates a certain resistance to the movement of the locking rod 11, the resistance is fed back to the pressing rod 6 through the locking mechanism, the user feels the “resistance” transmitted by the pressing rod 6, and thus the user can judge that the foot pedal 2 has moved to a certain angle; when the locking rod 11 is retracted, under the action of the elastic sheet 21, the push piece 23 is rotated to the initial position again, and waits for the next operation.
