Improved linkage brake structure

The present invention relates to an improvement of the linkage brake structure, the redesign of the bicycle linkage brake structure, which simplifies the excessive lack of components of the conventional structure, and the simplified linkage brake structure can improve assembly efficiency and increase product output.

According to the new type No. 86210399, 88214460, 89201453, 89208392, 89219206, M320532 previously applied by the applicant, the structure of the single-handle two-wheel brake is used to provide two-wheel synchronous brakes and when the front wheel brake line is disconnected, The single-handle two-wheel brake can also provide the unbroken brake cable to maintain its braking function. The aforementioned products are on the market and are welcomed and used by bicycle manufacturers at home and abroad.

The applicant continues to research and develop, and the problems arising after synchronous braking are used for the structure of the first wheel brake and then the front wheel brake for functional reinforcement to show the improved effect.

The main purpose of the present invention is to provide an improved linkage brake structure. Based on the aforementioned case, the bicycle linkage brake structure is further redesigned to simplify the excessive lack of conventional structural components. The simplified linkage brake structure can improve assembly efficiency and increase product output. .

The secondary purpose of the present invention is to provide an improved linkage brake structure. The front brake cable and the rear brake cable are respectively connected to the linkage unit, and an S spring buckle is provided, which can fix the position of the front brake cable and the rear brake cable, eliminating the need for extra Adjust the brake force tightly with a screw loosened The structure, in this way, can avoid spending time adjusting the proper positions of the front and rear brake cables and save costs.

Another object of the present invention is to provide an improved linkage brake structure. A linkage unit on the brake handle adopts a lever design, which can automatically adjust the position of the brake wire, and is connected between the fixing base and the linkage unit through a connecting hook. Evenly distribute the braking force, and use the connecting hook to prevent the front and rear brake cables from breaking as a backup brake.

Another object of the present invention is to provide an improved linkage brake structure. During the braking process, even if one brake cable is disconnected, the connecting hook can still maintain the brake function operation.

The structure that can achieve the above-mentioned purpose mainly includes: a fixed seat, a brake handle, a linkage unit, a snap unit, and a connecting hook;

The aforementioned fixing seat is installed on a faucet, and the fixing seat includes a rear brake cable introduction hole, a front brake cable introduction hole, a receiving part, a pivot hole, and a locking part from top to bottom; The brake cable lead-in hole provides a rear brake assembly assembly. The rear brake cable lead-in hole is used to assemble a rear brake adjustment knob of the rear brake assembly, and a rear brake cable of the rear brake assembly is installed on the rear brake assembly. In the brake adjustment knob; the front brake cable introduction hole provides a front brake cable assembly assembly, the front brake cable introduction hole provides the front brake assembly front brake adjustment knob assembly, and a front brake cable of the front brake assembly It is installed inside the front brake adjustment knob; the aforementioned locking part is to assemble the fixing seat to the faucet, and the front end of the fixing seat further includes a sliding groove part for assembling the snap unit;

The aforementioned brake handle is connected to the fixing base and provides user manipulation. The brake handle includes a driving part and a pivoting part. The driving part provides assembly of the linkage unit, and the pivoting part corresponds to the pivot hole. A shaft penetrates both so that the brake handle pivots with respect to the fixing base with the shaft rotating part as the center of rotation; furthermore, the driving part of the brake handle usually retracts Contained in the accommodating part;

The interlocking unit is installed on the driving part. The interlocking unit includes a rear brake line interlocking end, a front brake line interlocking end, and a interlocking center. The aforementioned rear brake cable is inserted into the rear brake inlet and connected to The rear brake cable linkage end, the front brake cable penetrates the front brake introduction hole and then is connected to the front brake cable linkage end, the linkage center portion penetrates the linkage center portion by a shaft, so that the linkage unit is centered on the linkage center As the center of rotation, when in use, the brake handle pulls the rear brake cable and the front brake cable moves to produce a linked brake; and the aforementioned snap unit contacts the rear brake adjustment knob and the front brake adjustment knob after the adjustment The position of the brake cable and the front brake cable; in addition, the connecting hook penetrates the fixing seat from the central part of the linkage and hooks on the side wall of the fixing seat.

In the embodiment of the present invention, a parking mode is further included to prevent the bicycle from sliding when parking. The feature is that the brake handle is provided with a brake end connected to one side of the shaft rotation part, and the fixing seat A brake button is provided at a predetermined position. The brake button has a notched end and a pressing shaft. When in use, the brake button is pressed so that the brake end abuts against the pressing shaft of the brake button to achieve a locked state , Without parking mode, press the brake button, so that the brake end is embedded in the notch end, in this state, the brake function is not generated.

In the aforementioned embodiment, a spring is provided on the notch end of the brake button, and the function of the brake button is achieved by the spring.

In the embodiment of the present invention, the rear brake adjustment knob and the front brake adjustment knob are respectively provided with an arc-shaped locking groove, and the snap unit is connected to the locking groove.

In the embodiment of the present invention, the accommodating portion is provided with a limit shim, the limit shim has a notch, the notch corresponds to the brake button, and restricts the position of the brake button to prevent rotation, Accordingly, the effect of restraining the brake button is achieved by the limiting washer.

Through the above structure, the effects that the present invention can provide are briefly described as follows:

1. Use the snap unit to produce the snapping function of the rear brake adjustment knob and the front brake adjustment knob, so that the adjustment of the rear brake cable and the front brake cable is faster, and it is not necessary to install the front brake cable and the rear brake cable with the conventional structure. , The installation is complicated, and the position of the rear brake cable and the front brake cable need to be fixed by the nut.

2. The linkage unit of the present invention adopts a lever setting. When the brake handle is pressed, the leading end drives the rear brake cable and the front brake cable to produce a braking action. The linkage unit automatically adjusts the positions of the rear brake cable and the front brake cable based on its characteristics.

3. When parking, press the brake button to maintain the brake state, prevent the bicycle from sliding, and keep the parking safe.

4. Further cooperation with the connecting hook can prevent the improper pressing force from breaking the rear brake cable and the front brake cable, and has the function of a backup auxiliary brake.

5. In the present invention, one side of the rear brake cable is connected to the upper end of the linkage unit, and one side of the front brake cable is connected to the lower end of the linkage unit. The advantage of this is that when braking, the rear wheels are firstly braked, and then the front wheels are braked, which can prevent It has a safety effect when it rolls over.

6. In addition to being installed on a single side to achieve the purpose of front and rear linkage brakes, the present invention can also be divided into two groups of left and right brakes at the bicycle faucet. The left and right brakes are respectively connected to the front brake assembly and the rear brake assembly. , In this way, just like the normal bicycle brake use, further by the setting of the connecting hook, it can prevent the front brake cable and the rear brake cable from being too tightly controlled and causing the disconnection.
