Description

Bicycle brake handle

A bicycle brake handle is mainly used for bicycles. The rotation of the handle simultaneously drives the rotation of the brake wire to control the braking and deceleration of the bicycle.

In recent years, with the popularity of sports, the bicycle market is booming. Whether it is a general bicycle used as a means of transportation and leisure and entertainment, or a high-end bicycle used for competition, it has been loved by consumers. In order to attract consumers to buy bicycles, many Manufacturers continue to improve the quality of products in terms of equipment to meet consumer expectations and needs.

The brake is one of the important equipment for the user when riding a bicycle. It mainly uses the principle of lever and the operation mechanism of friction to make the wheels of the bicycle in the forward state receive friction and resistance to achieve the effect of deceleration and braking, such as the Taiwan patent In No. I624401 "Brake Adjustment System for Two-wheeled Vehicles", as shown in Figures 5 to 12, the adjustment kit, adjustment parts and elastic elements provide a better braking feel. When the rider presses the brake lever, the elastic elements can be driven The brake cable slows down or brakes the brake pad clamping the steel ring.

However, although the above-mentioned braking effect can be achieved by pressing the brake lever, when the user’s palm rests against the grip and the fingertips and part of the knuckles hook the brake lever in a buckled state, the user must pass through the fingertips and parts of the finger The knuckles provide enough pressing force to drive the brake lever to move toward the grip. Compared with the average adult male, the pressing force provided by the fingers of women and the elderly Relatively insufficient, when riding a bicycle, it is easy to press the brake lever to slow down or brake due to insufficient pressing force, which may lead to traffic accidents.

Therefore, based on the above-mentioned problems encountered in the conventional technology, the inventors need to further think about how to solve the above-mentioned conditions and problems.

In order to solve the above-mentioned problems of the prior art, the inventors of the present invention provide a bicycle brake handle. By turning the handle, the bicycle can be braked or decelerated in time to avoid traffic accidents.

In order to achieve the above objectives and effects, the present invention provides a bicycle brake handle, including: a brake turntable, the inner concave ring of the outer peripheral side is provided with a ring groove, the ring groove communicates with a clamping hole; a brake wire, part of which is arranged in In the ring groove, one end of the brake wire is provided with a fixing block, the fixing block is clamped with the clamping hole; a connecting piece, which is tubular and one end is assembled and fixed with the brake turntable, the connecting piece rotates and simultaneously drives the The brake dial and the brake wire rotate.

In order to more clearly illustrate the objectives and effects that the present invention can achieve, the embodiments of the present invention are described in detail with figures. Please refer to Figures 1 to 6A. The present invention provides a bicycle brake handle, including: A brake turntable 1 with an inner concave ring on the outer peripheral side provided with a ring groove 11, and the brake turntable 1 is provided with a clamping hole 12, the ring groove 11 communicates with the clamping hole 12; a brake wire 2, part of which is arranged in One end of the ring groove 11 and the brake wire 2 is provided with a fixing block 21 which is clamped to the clamping hole 12; The connecting member 3 rotates and drives the brake dial 1 and the brake wire 2 to rotate at the same time.

The aforementioned bicycle brake handles can be assembled on the left and right sides of the handle 8, and the following takes the bicycle brake handle assembly connected to the right handle 8 as an example for description. As shown in Figures 4 to 6A, the bicycle brake handle is assembled by the brake dial 1, the brake wire 2 and the connecting piece 3. The connecting piece 3 is assembled with the handle 8 of the bicycle, so that the user can use The bicycle brake handle and the bicycle grip 8 control the forward direction of the bicycle during riding. When the bicycle brake handle is turned, the connecting piece 3 can drive the brake dial 1 and the brake cable 2 to rotate at the same time, and the brake cable 2 can drive the brake clamp 5 to operate. , The brake clamp 5 can clamp the two sides of the wheel set 6, so that it can achieve the effect of braking and deceleration, and the handle 8 of the bicycle will not rotate with the connecting piece 3 and the brake dial 1 during the rotation process.

It can be seen from the above that, compared with the conventional deceleration and braking effect by pressing the brake lever, the bicycle brake handle is rotated to achieve the deceleration and braking effect. The bicycle brake handle of the present invention provides the user's fingers and palms, which can cover the bicycle brake handle and provide sufficient gripping area, which is convenient for the user to slow down and brake in time. As shown by the arrow in the figure, the above method can improve the conventional wisdom. Compared with the average adult male, the pressing force provided by the fingers of women and the elderly is relatively insufficient. When riding a bicycle, the brake lever cannot be pressed in time to slow down or brake, resulting in Problems in traffic accidents.

Besides, bicycle brake handles can be used for bicycles that are stepped forward by traditional humans, and can also be used for electric bicycles. The electric bicycle referred to here refers to electric bicycles that are mainly stepped on by humans and assisted by electric power. The following is general Take the traditional human pedaling bicycle as an example.

Next, as shown in the second and third figures, the brake turntable 1 includes a ring portion 13 and a convex portion 14 connected to the outer periphery of the ring portion 13 and integrally formed. The ring groove 11 is located at the ring portion 13 and the convex portion 14. The clamping hole 12 is located at the convex portion 14. When the fixing block 21 is installed in the clamping hole 12, the brake wire 2 can be partially arranged in the ring groove 11.

The brake turntable 1 axially penetrates a positioning hole 15 and the connecting member 3 is partially penetrated in the positioning hole 15. The positioning hole 15 is provided with a plurality of positioning grooves 151 around the circumference of the hole wall. The plurality of positioning blocks 31, when the plurality of positioning grooves 151 and the plurality of positioning blocks 31 are assembled with each other, the connecting member 3 can be assembled and fixed with the brake turntable 1 without loosening.

As shown in Figures 3 to 6A, in order to improve the comfort of holding, the bicycle brake handle further includes a non-slip grip 4, which is sleeved on one end of the connector 3, and the brake dial 1 faces One side of the non-slip grip 4 has a retaining portion 16 which has a retaining surface 161 and a retaining surface 411 of a retaining portion 41 extending outward from one end of the non-slip grip 4 to contact each other. , The anti-skid grip 4 and the brake turntable 1 are locked and fixed, and the anti-skid grip 4 can simultaneously drive the connecting piece 3, the brake turntable 1 and the brake wire 2 to rotate.

In addition, the present invention further includes a sleeve 7, a part of the brake wire 2 extends out of the ring groove 11, passes through the sleeve 7 and is connected with the brake clamp 5. The sleeve 7 can be protected when the bicycle is running outdoors or placed outdoors The brake cable 2 avoids rusting caused by contact with rain or other liquids.

Finally, based on the above, the embodiments of the "bicycle brake handle" of the present invention are only used to explain the preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Therefore, everything is in the same spirit of the invention. Any modifications or changes made to the present invention that are in other forms that can be implemented and have the same effect should still be included in the scope of the present invention's intended protection.
