Description

Brake stop structure

This creation is related to the field of grip type brakes, in particular to a kind of brake blocking structure.

With the evolution of the times and the impact of the domestic traffic environment, the means of transportation used by modern people are no longer limited to cars, buses, etc. Bicycles and motorcycles are also quite popular in China as means of transportation.

On most bicycles and motorcycles, the handle brake structure is usually used, and the brake system is driven by pressing the handle for braking. This kind of braking method is relatively simple and in line with human intuition, so it is usually equipped on relatively slow vehicles. This kind of brake structure.

Most of today's large motor vehicles such as cars, trucks or trucks are equipped with a hand brake system. The hand brake system can effectively block the tires continuously and prevent the tires from rolling and sliding to cause the vehicle to shift. When driving a vehicle, the trolley will be pulled up for insurance.

However, the common motorcycles, bicycles and electric bicycles on the market today are not equipped with a handbrake system. Therefore, when these small vehicles are parked on a slope, even if the parking pole is stepped on, as long as the tires touch the road, there is still a possibility that the vehicle may appear. In a sliding situation, even when waiting for a red light, the leaning of the body can cause the vehicle to slide forward or backward, and then accidentally hit someone.

Therefore, if the above-mentioned situation can be optimized and improved, the safety and applicability of small vehicles such as motorcycles or bicycles can be effectively increased.

The main purpose of this creation is to provide a brake stopper structure. By installing a stopper on the grip body seat of a motorcycle or bicycle, which is controlled by the stopper control and can be interlocked with the rebound action of the brake handle, After pressing the brake lever, the user can pull the card control to drive the rebound action between the card stopper and the brake lever, and then keep the brake lever in the braking state, achieving a structure similar to the hand brake of a car. To prevent the tire from rolling, compared with the previous technology, this creation is equivalent to a structure with a hand brake on the motorcycle or bicycle, which makes the user safer when parking the motorcycle or bicycle, and increases the speed of the motorcycle or bicycle on the road. applicability.

In order to achieve the above-mentioned purpose and effect, this creation provides a brake blocking structure, which includes a main body seat, a brake handle, a linkage block, a locking block and a locking control. The extension part extending outward is provided with an accommodating groove inside the extending part, and the accommodating groove is provided with a slide rail.

The brake handle system includes an outer handle part and a built-in part, the outer handle part protrudes outside the accommodating groove, the built-in part is pivotally arranged in the accommodating groove, and the built-in part protrudes toward the buckle. convex hook.

Furthermore, the interlocking block is arranged inside the accommodating groove, and the interlocking block includes a shaft hole and a structural rib, and the structural rib protrudes from one side of the shaft hole.

Then, the blocking block is provided with the accommodating groove and is located on one side of the interlocking block, and the blocking block includes a block part, a push-pull part and a blocking part, wherein the block part is arranged toward one side of the buckle There is a spring, and one end of the spring is set on the block body, and the other end is connected to the inner wall of the accommodating groove. The block body extends and protrudes toward the inside of the accommodating groove, the blocking portion is spaced from the push-pull portion, and the blocking portion is provided with a blocking surface, and the blocking block is additionally provided with a fine-tuning screw that penetrates and protrudes from the locking portion. On the retaining surface, the block body is protrudingly provided with a convex rib to slide on the slide rail, and the blocking block slides on the slide rail through the convex rib.

Finally, the card control system includes an interconnected lever and a connecting column, wherein the lever is located on the surface of the extension part and extends toward one side, and the connecting column is axially passed through the extension part, the accommodating groove and the rotating shaft hole.

In actual use, when the user needs to activate the brake locking function, the user needs to first turn the outer handle of the brake lever under the normal condition of the brake system (the first state, that is, the state where the brake lever is pushed outward in the opposite direction to the buckle lever). Press back toward the buckle handle, and then drive the convex hook to move toward the inner side of the accommodating groove (the second state), and then, under the state of keeping the outer handle part continuously pressed back, pull the lever so that the connecting column drives the linkage block The structural rib of the structure moves toward the brake handle, and then the structural rib pushes against the blocking block and moves along the slide rail toward the brake handle (the third state). Then, when the brake handle is released, the brake handle will rebound and be blocked The fine-tuning screw of the block is stuck, and finally the lever is released. The block and the brake lever will continue to try to rebound to the normal state (the first state) due to the structure, but the rebound action of the two will be due to the protrusion and the fine-tuning screw. They are interlocked with each other, so that the two cannot rebound to their original positions, and finally the brake handle is kept in a braking state (the fourth state) in which the outer handle portion is continuously pressed back.

And if will remove above-mentioned 4th state, make it get back to normal state (first state), only need in the 4th state and press outside handle part back again, make protruding hook break away from block block, block block will be because of The spring is affected and twisted back, so that the locking block, the interlocking block and the locking control return to the first state position, and then the outer handle is released to make the brake handle turn back, that is, return to the first state.
