Example 1

The embodiment of the disclosure provides a brake mechanism of a bicycle, which comprises a brake and a brake cable, wherein the brake is provided with a first section, a second section and a transition section arranged between the first section and the second section, the first section is hinged to a fork arm of the bicycle, the second section is connected with one end of the brake cable, and the brake cable is configured to drive the transition section of the brake to be tightly held with a brake shaft of the wheel under the action of external force so as to provide a braking resistance to the brake shaft of the wheel.

The brake mechanism of the bicycle will be described in detail with reference to fig. 1 to 2. In which fig. 1 schematically shows a structural view of a brake mechanism of a bicycle according to an embodiment of the present invention, and fig. 2 schematically shows an enlarged view at a in fig. 1.

As shown in fig. 1 to 2, the brake mechanism 100 according to the embodiment of the utility model includes a brake 1 and a brake cable 2, the brake 1 has a first section 10, a second section 11 and a transition section 12 disposed between the first section 10 and the second section 11, the first section 10 is hinged to a fork arm 3 of the bicycle, the second section 11 is connected to one end of the brake cable 2, and the brake cable 2 is configured to drive the transition section 12 of the brake 1 and a brake shaft 5 of a wheel 4 to be tightly held under an external force so as to provide a braking resistance to the brake shaft 5 of the wheel 4. It should be understood that the external force is provided by the braking handle, and the braking handle drives the braking cable when braking, so as to realize the stress of the braking cable.

The working process of the brake mechanism 100 of the embodiment of the utility model is as follows: under the action of external force, the brake cable 2 drives the brake 1 to rotate towards the direction close to the brake shaft 5 until the brake 1 and the brake shaft 5 are tightly held, thereby completing the braking action.

For example, the brake mechanism 100 further includes a limit component 6, the brake cable 2 is provided with a limit matching part 20, and the limit matching part 20 and the limit component 6 are matched to limit the brake 1 to rotate continuously under the condition that the brake 1 rotates to a preset position in the direction away from the brake shaft 5 after the external force disappears. Through the cooperation of the limiting matching part 20 and the limiting component 6, the brake 1 can be prevented from continuously driving the brake cable 2 to move downwards after rotating to a preset position.

Specifically, the limiting component 6 includes a brake cable seat 7 and a limiting member 8, the limiting member 8 includes an installation portion 80 and a limiting portion 81, the installation portion 80 is disposed on the brake cable seat 7, the limiting portion 81 is formed with a limiting groove 82, and when the brake 1 rotates to a predetermined position in a direction away from the brake shaft 5 after the external force disappears, at least a part of the limiting matching portion 20 is limited in the limiting groove 82.

For example, the transition section 12 of the brake 1 is an arc-shaped structure matched with the brake shaft 5 of the wheel 4, so that the transition section 12 and the brake shaft 5 are tightly held to the greatest extent, and further, greater braking resistance is generated, and the brake is quicker.

For example, the transition section 12 of the brake 1 is provided with brake shoes 9, and the shape of the brake shoes 9 is matched with the shape of the transition section 12. The brake shoe 9 provides greater brake resistance to the brake shaft 5, thereby improving the brake effect. Optionally, the brake shoes 9 are detachably attached to the inner side walls of the transition section 12 of the brake 1. Under the long-term condition, when the brake shoe 9 is worn, the brake shoe 9 can be detached from the brake 1 to replace a new brake shoe 9, so that the condition that the whole brake 1 is scrapped is avoided.

For example, the brake cable 2 is fixed to the second section 11 of the brake 1 by a fixing screw 13, and a brake cable presser 14 is provided between the fixing screw 13 and the brake cable 2.

In summary, the brake mechanism 100 according to the embodiment of the present invention can perform a braking operation only by the cooperation of the brake cable 2 and the brake 1, and the number of parts used is small, so that the brake mechanism 100 has the advantages of low cost and simple production and assembly.
