The brake device provided by the invention is particularly suitable for bicycles and electric vehicles operated in a sharing mode, so that the problems of abrasion of the brake piece 2 and attenuation of brake performance caused by high-frequency use of the brake device are solved.

According to a first aspect of the present application, a brake apparatus is provided, as shown in fig. 1 and 2, comprising a housing 1, a brake member 2, a rotating shaft 3, a threaded adjusting rod 5, a toggle part 7 and a mounting assembly 8. The shell 1 is used for bearing other parts of a brake device, and the shell 1 can be fixedly arranged on the body of a shared vehicle. The housing 1 may be a box-shaped structure formed with an accommodating cavity and capable of arranging a brake piece 2, a rotating shaft 3, a threaded adjusting rod 5 and other components in the accommodating cavity. The housing 1 may also be a plate-shaped or block-shaped structure for providing a support member for the brake member 2, the rotating shaft 3, the threaded adjusting rod 5, and the like.

The braking member 2 is used for contacting with the wheel assembly to form friction, and when the wheel assembly rotates, the braking member 2 reduces the rotating speed of the wheel assembly through friction resistance. The brake element 2 is movably arranged on the housing 1. For example, the braking member 2 forms a matching connection manner of relative rotation with respect to the housing 1, specifically, the braking member 2 may be similar to a crescent structure, the first end of the braking member 2 is rotatably connected with the housing 1, and the braking member 2 rotates integrally with the first end of the braking member 2 as an axis, so that the braking member 2 rotates with respect to the housing 1. In other embodiments, the brake element 2 and the housing 1 can also be connected in a relative linear movement or other fit.

The shaft 3 serves to transmit an external force into the brake device to move the brake element 2 to form friction with the wheel assembly. For example, the turned end extends outside the housing 1 and forms a connection with a brake cable or a brake hydraulic tube or the like. The brake cable can be connected to a brake handle at the handle of a bicycle or a motorcycle, so that the acting force for controlling the brake handle is transmitted to the rocker and the rotating shaft 3 to drive the rotating shaft 3 to move. In other applications, the brake hydraulic pipe can be connected to a brake pump and a brake pedal of an automobile, and the brake hydraulic pressure is transmitted through the brake pump and the brake pedal to control the brake device to brake. The rotating shaft 3 is rotatably arranged on the shell 1, the rotating part 4 is arranged on the rotating shaft 3, namely, the rotating shaft 3 rotates relative to the shell 1 under the action of external force, and the rotating shaft 3 can drive the brake piece 2 to move in the rotating process, so that the brake piece 2 moves to the position where the brake piece is rubbed with a wheel assembly. The rotating part 4 on the rotating shaft 3 rotates along with the rotation of the rotating shaft 3, and the rotating part 4 can drive the shifting part 7 to move when rotating, so that favorable conditions are provided for adjusting the position of the brake piece 2 and compensating the abrasion part of the brake piece 2.

The thread adjusting rod 5 is in threaded connection with the brake piece 2, specifically, one end of the thread adjusting rod 5 is provided with threads, the brake piece 2 is provided with a screw hole for the thread adjusting rod 5 to be inserted, and the thread adjusting rod 5 is matched with the screw hole in the brake piece 2 through thread fixing on the thread adjusting rod, so that the thread adjusting rod 5 is fixed on the brake piece 2. The rotating shaft 3 can drive the threaded adjusting rod 5 to move when rotating, and then drives the brake piece 2 in threaded connection with the threaded adjusting rod 5 to move to a brake position. The threaded adjusting rod 5 is provided with a ratchet wheel 6, and specifically, the ratchet wheel 6 teeth are integrally formed on the threaded adjusting rod 5 along the circumferential direction. In another embodiment, the independent ratchet 6 may be sleeved on the threaded adjusting rod 5, and the ratchet 6 sleeved on the threaded adjusting rod 5 and the threaded adjusting rod 5 are circumferentially fixed. The rotation of the ratchet wheel 6 can drive the threaded adjusting rod 5 to rotate relative to the brake piece 2 under the effect of threaded connection, so that the relative position relation between the threaded adjusting rod 5 and the brake piece 2 is adjusted, the change of the position of the brake piece 2 is facilitated, and the abrasion of the brake piece 2 in the using process is compensated.

That is to say, the rotating part 4 can drive the shifting part 7 arranged on the shell 1 to move when moving along with the rotating shaft 3, and at the moment, the shifting part 7 shifts the ratchet wheel 6 which is offset with the shifting part to move, so that the position of the brake part 2 is adjusted, and the abrasion of the brake part 2 is compensated.

Under the condition that the rotating shaft 3 rotates along the first direction, the threaded adjusting rod 5 drives the braking piece 2 to move to the braking position. In the above process, in the case that the rotating shaft 3 rotates in the first direction by an angle greater than a predetermined angle, the toggle part 7 can deflect to an inclined state under the action of the mounting assembly 8 to engage with the ratchet 6. For example, when a user presses a brake handle to tighten a brake cable and pull the rocker arm 12, the rotation shaft 3 is driven to rotate relative to the housing 1 by the movement of the rocker arm 12, and the rotating part 4 rotating along with the rotation shaft 3 drives the toggle part 7 to move so that the toggle part 7 slides along the circumferential direction of the ratchet 6. When the shifting part 7 slides to the limit position, the shifting part 7 can deflect relative to the shell 1 under the action of the mounting assembly 8, so that the contact part of the shifting part 7 and the ratchet wheel 6 is positioned at or close to the bottom of the tooth groove between two adjacent ratchet teeth, and the meshing state of the shifting part 7 and the ratchet wheel 6 is ensured.

It should be noted that when the rotating shaft 3 rotates in the first direction by an angle smaller than the predetermined angle, the rotating shaft 3 can still drive the braking member 2, so that the braking member 2 moves toward the wheel assembly.

Under the condition that the rotating shaft 3 rotates and resets along the second direction, the poking part 7 pokes the ratchet wheel 6 to rotate relative to the braking piece 2, so that the braking piece 2 moves relative to the threaded adjusting rod 5 towards the direction close to the braking position. For example, when the user releases the brake handle, the brake cable is loosened to reset the swing arm 12 by the reset member, so that the swing arm 12 rotates the rotating shaft 3 in a second direction opposite to the first direction. At this time, the rotating part 4 on the rotating shaft 3 drives the shifting part 7 to move, so that the shifting part 7 shifts the ratchet wheel 6 to rotate by a predetermined angle, and further the threaded adjusting rod 5 rotates by a predetermined angle relative to the brake piece 2. Through the threaded connection relation, after the threaded adjusting piece rotates, the overlapping part between the threaded adjusting piece and the braking piece 2 is reduced, so that the size of the threaded connecting piece and the size of the braking piece 2 in the direction from the rotating shaft 3 to the braking piece 2 are increased, and the increased size is the size compensated for the worn braking piece 2 in the application.

Meanwhile, since the reset stroke of the rocker arm 12 is smaller than the braking stroke of the rocker arm 12, the actual rotation angle of the ratchet wheel 6 dialed by the dialing part 7 is smaller than the preset rotation angle of the ratchet wheel 6. Under the condition that stirring portion 7 can not have obvious deflection for casing 1, for example stirring portion 7 sets up on pivot 3, when making rocking arm 12 rotate again and brake, the stroke of stirring portion 7 motion can not make stirring portion 7 in time with next ratchet interlock, leads to in time adjusting brake spare 2. And in this application stir portion 7 can deflect for casing 1 under the effect of installation component 8, guarantee stir portion 7 with the interlock state of ratchet 6 has guaranteed that this application can in time adjust brake spare 2. Simultaneously, stirring portion 7 in this application independently sets up on the casing 1, increased stirring portion 7's flexibility.
