Description

Technical Field

[0001] The utility model relates to the field of vehicle engineering, in particular to a deceleration and noise reduction structure for a pedal. Background Art

[0002] The clutch pedal of a car will rebound quickly after being stepped on, causing fatigue in the user's feet and affecting driving safety. In response to this problem, the invention patent application with publication number CN115091946A and name "adjustable cushioning force pedal structure" proposes that during the resetting process of the pedal bracket, the cushioning effect of the auxiliary cushioning rod is used to avoid immediate flipping and rebounding, thereby reducing the vibration to the user and reducing the user's fatigue. The cushioning force adjustment knob is used to adjust the flux of the return oil circuit of the auxiliary cushioning rod, thereby adjusting the reaction force generated by the oil pressure in the auxiliary cushioning rod when the pedal is reset, and then adjusting the pedal reset damping buffering effect, further improving the feedback of the pedal. Although this method solves the problem of rapid rebound after the pedal is stepped on, the feedback of the stepping process and the rebound process is not smooth, and the user cannot accurately control the size of the stepping force, which will still cause foot fatigue. In addition, this structure has a certain amount of noise during the pedal stepping and rebound process, which affects the user experience and driving safety. Utility Model Content

At the same time, the movement of the movable rod 4 must also be guided by the rotating sleeve 7 on the flip seat 3, so the movement state of the movable rod 4 is stable. When the movable rod 4 passes through and makes axial movement relative to the rotating sleeve 7, the guide member 71 on the rotating sleeve 7 makes a spiral movement relative to the movable rod 4 under the guiding and limiting action of the spiral groove 41, and the guide member 71 drives the rotating sleeve 7 to rotate under the action of the force of the spiral groove 41, and then cooperates with the elastic member 6 to support the movable rod 4, so that the movable rod 4 can be stepped on. During the whole process of stepping on the pedal body 2, the reaction force transmitted to the pedal body 2 by the movable rod 4 through the connecting rod 5 changes relatively linearly. During the resetting process of the pedal body 2, due to the constraint of the spiral groove 41 on the guide member 71, the movable rod 4 will not suddenly reset under the action of the elastic member 6, but will rebound more smoothly and gently as the guide member 71 moves along the spiral groove 41 to the initial point and the rotating sleeve 7 rotates and resets. Through the above-mentioned structural design, firstly, the stability and smoothness of the feedback of the clutch pedal stepping process and the rebound process are improved, and the user can accurately control the size of the stepping force and reduce foot fatigue. Secondly, through the coordinated cooperation of the spiral guide mechanism and the elastic member 6, compared with the single use of springs, damping rods and other types, the process noise is small, which is conducive to improving the user experience. Thirdly, the most important thing is to improve the driving safety of the user.

[0047] The flip seat 3 is provided with a mounting hole 31, and the rotating sleeve 7 is rotatably arranged in the mounting hole 31. The rotating sleeve 7 is provided with a through hole 72 for the movable rod 4 to pass through, and the through hole 72 is coaxially arranged with the mounting hole 31. The guide member 71 is a top ball. The rotating sleeve 7 is provided with a clamping groove 73 that is clamped with the top ball.

The base 1 is provided with a guide groove 11, and the movable rod 4 is provided with a sliding rod. The sliding rod is rotatably connected with a bearing 34 slider, and the bearing 34 slider is slidably connected with the guide groove 11. The guide groove 11 includes a horizontal groove 111 and a sinking groove 112 that are connected to each other. The base 1 is provided with a mounting groove 12, and the flip seat 3 is provided with a support column 36, and the support column 36 is rotatably arranged in the mounting groove 12. The mounting groove 12 is a J-shaped groove. The hook of the J-shaped groove is located on the extension line of the horizontal groove 111, which ensures that the movable rod 4 does not rotate in the initial stage of pedaling, but only translates along the axis, thereby improving the stability and smoothness of the pedaling process. The elastic member 6 is a spring.

At the same time, the movement of the movable rod must also be guided by the rotating sleeve on the flip seat, so the movement state of the movable rod is stable. When the movable rod passes through and makes axial movement relative to the rotating sleeve, the guide part on the rotating sleeve makes spiral movement relative to the movable rod under the guiding and limiting action of the spiral groove, and the guide part drives the rotating sleeve to rotate under the action of the force of the spiral groove, and then cooperates with the elastic part to support the movable rod, the whole process of stepping on the pedal body can be achieved. The change of the reaction force transmitted to the pedal body by the movable rod through the connecting rod is relatively linear.

Thirdly, the most important thing is to improve the driving safety of the user.
