Control device for adjusting bicycle suspension system

Abstract

This invention discloses a control device for adjusting a bicycle suspension system, comprising a housing, an operating component, and a level adjustment component. The user can pivot a rotating disc in one direction by moving a lever on the operating component, thereby causing the level adjustment component to produce linear displacement, allowing it to move with either a first or second linear displacement stroke. When the control device is installed on the bicycle's suspension system, simply moving the lever in one direction adjusts the preload of the fork or seatpost. When the level adjustment component reaches its second linear displacement stroke, the preload of the fork or seatpost returns to zero, allowing for quick adjustment to suit different terrains.

Claims

1. A control device for adjusting a bicycle suspension system, comprising: a housing having an internal receiving space; an operating component having a lever, a rotating disk, and a cable, the rotating disk being pivotally connected to the housing and received within the receiving space, the lever being connected to the rotating disk, one end of the cable being connected to at least one of the lever or the rotating disk, the other end of the cable being connected to a bicycle suspension system, and the lever protruding to the outside of the housing, wherein when the lever pivots the rotating disk in one direction, it simultaneously pulls the cable to operate the suspension system; and a level adjustment component, received within the receiving space of the housing, the level adjustment component having a stop mechanism for locking the rotating disk of the operating component, when pivoted in one direction, at at least two pivot angle positions; wherein... When the lever of the operating component drives the rotating disk to pivot in the same direction, it causes the segment adjustment component to generate a linear displacement. When the segment adjustment component moves with a first linear displacement stroke, it can sequentially move the rotating disk and lock it at one of the pivot angle positions. When the segment adjustment component moves with a second linear displacement stroke that is less than the first linear displacement stroke, it can release the pivot angle position that the rotating disk has locked, and the rotating disk can pivot back to the previous pivot angle position in the opposite direction or return to the original position.

2. The control device for adjusting a bicycle suspension system as described in claim 1, wherein the stop mechanism of the adjustment component has a fixed shaft, a movable shaft, and a positioning element. One end of the fixed shaft is provided with a first locking tooth and connected to the movable shaft. One end of the movable shaft is connected to the rotating disk of the operating component, and the other end forms a displacement segment. A second locking tooth and an elastic element are provided in the displacement segment. The second locking tooth can move along the displacement segment. The elastic element is sleeved on the displacement segment, and one end of the elastic element abuts against one side of the first locking tooth, and the other end abuts against one side of the second locking tooth. The positioning element has a first hook and a second hook, which are spaced apart by a distance.

3. The control device for adjusting a bicycle suspension system as described in claim 2, wherein one side of the rotating disk of the operating component is connected to one end of the lever, the other side of the rotating disk forms a plurality of teeth, and one end of the movable shaft of the position adjustment component forms a plurality of equidistant flanges, wherein, according to the rotation of the rotating disk, different teeth engage with different flanges, causing the movable shaft to drive the fixed shaft to produce displacement.

4. The control device for adjusting a bicycle suspension system as described in claim 2, wherein when the rotating disc is locked at one of the pivot angle positions, the first locking tooth abuts against the first hook or the second hook; when the rotating disc is released from the locked pivot angle position, the second locking tooth abuts against the first hook or the second hook, and when the lever is released, the rotating disc pivots in the opposite direction back to the previous pivot angle position or back to the origin position.

5. The control device for adjusting a bicycle suspension system as described in claim 4, wherein one side of the first tooth of the fixed shaft of the position adjustment component is an inclined surface and the other side is an abutment surface, and when the position adjustment component performs the first linear displacement stroke displacement, the inclined surface of the first tooth abuts against and then passes over the first hook or second hook of the positioning element, and the abutment surface abuts against the first hook or second hook of the positioning element.

6. The control device for adjusting a bicycle suspension system as described in claim 5, wherein the abutting surface of the first tooth of the fixed axle is an inwardly recessed structure.

7. The control device for adjusting a bicycle suspension system as described in claim 4, wherein both sides of the second tooth of the fixed shaft of the position adjustment component are inclined surfaces; when the position adjustment component performs the second linear displacement stroke, the second tooth abuts against and then passes over the first hook or second hook of the positioning element; when the position adjustment component performs the second linear displacement stroke and releases the lever, the second tooth abuts against the first hook or second hook of the positioning element, and causes the second tooth to move along the displacement segment toward the first tooth; after compressing the elastic element, the second tooth passes over the first hook or second hook to return to the previous pivot angle position or the origin position.

8. The control device for adjusting a bicycle suspension system as described in claim 2, wherein one end of the positioning element of the adjustment component is pivotally connected to the housing via a torsion spring.

9. The control device for adjusting a bicycle suspension system as described in claim 2 or 8, wherein a first hook and a second hook of the positioning element of the position adjustment assembly protrude outward from one side of one of the swing arms of the positioning element, and the first hook and the second hook are obliquely arranged relative to the swing arm.
