In one aspect of the embodiment of the present application, a braking device is provided, as shown in fig. 1, the braking device includes an air bag 140, a fixing frame 130, and a pump body 110, wherein the pump body 110 is slidably disposed on the fixing frame 130, the air bag 140 is located between the pump body 110 and the fixing frame 130, and a braking assembly 120 that can be driven by the pump body 110 is disposed on the pump body 110.

In practical applications, the braking device is fixedly disposed on a frame of a vehicle, such as a front fork or a rear fork of the vehicle, via the fixing frame 130, so that the braking assembly 120 is correspondingly engaged with a brake disc of a wheel, and when necessary, the braking assembly 120 can be driven by the pump body 110 to contact and rub the brake disc, thereby achieving braking. Specifically, the method comprises the following steps: as shown in fig. 1, the brake assembly 120 provided on the pump body 110 includes a first brake pad 121 and a second brake pad 122 which are opposite to each other, so that a cavity is formed between the first brake pad 121 and the second brake pad 122, and a brake disc of a vehicle is correspondingly located in the cavity, wherein the first brake pad 121 and/or the second brake pad 122 can be driven by the pump body 110, so that the distance between the first brake pad 121 and the second brake pad 122 can be correspondingly changed under the driving of the pump body 110, so that in a braking state, the distance between the first brake pad 121 and the second brake pad 122 is reduced by the driving of the pump body 110, and the brake disc between the first brake pad 121 and the second brake pad 122 is clasped to realize braking.

When the braking device is fixedly arranged on the frame through the fixing frame 130 and braking is required, as shown in fig. 1, the first brake pad 121 is fixedly arranged at the driving end of the pump body 110, the second brake pad 122 is fixedly arranged on the pump body 110 (the second brake pad 122 is not driven by the pump body 110), the pump body 110 drives the first brake pad 121 to contact with a brake disc, at this time, the pump body 110 slides relative to the fixing frame 130 based on the relation between the acting force and the reacting force, so that the second brake pad 122 can also contact with the brake disc, and the brake disc is tightly held by the first brake pad 121 and the second brake pad 122. Of course, the pump body 110 is only a single-cylinder drive, that is, one of the first brake pad 121 and the second brake pad 122 can be driven by the pump body 110, and the other is fixedly disposed on the pump body 110, and the other is in contact with the brake disk by means of acting force and reacting force. In other embodiments, the pump body 110 may also be double-cylinder opposed, such that the pump body 110 has two driving ends, and the first brake piece 121 is fixedly disposed at the first driving end, and the second brake piece 122 is fixedly disposed at the second driving end.

As shown in fig. 1 to 4, a certain amount of gas is contained in the inner cavity 141 of the air bag, the air bag 140 is located between the pump body 110 and the fixing frame 130, and opposite ends of the air bag 140 are fixedly connected with the pump body 110 and the fixing frame 130, respectively, so that the pump body 110 is in an initial position (as shown in fig. 4) under the action of the air bag 140; as shown in fig. 4, when the pump body 110 slides rightward at the initial position (since the fixing frame 130 is fixed to the frame, the fixing frame 130 can be regarded as being stationary for the sake of understanding, the air bag 140 is stretched, the air density of the inner cavity of the air bag 140 becomes small, a negative pressure chamber is formed, and thus, a leftward restoring force is provided to the pump body 110; when the pump body 110 slides leftwards relative to the fixed frame 130 at the initial position, the air density of the inner cavity of the air bag 140 is increased to form a positive pressure cavity, so that the pump body 110 is subjected to a rightwards resetting force; therefore, in a natural state, the position of the pump body 110 and the fixed frame 130 is relatively fixed (initial position) under the action of the air bag 140, and the relative position is determined by the total amount of the gas in the inner cavity of the air bag 140.

It should be understood that, in long-term use, the relative position (initial position) between the pump body 110 and the fixing frame 130 may cause a certain contact between the brake assembly 120 on the pump body 110 and the brake disc in a non-braking state due to poor return of the pump body 110, so as to cause an abnormal sound problem in normal driving, in order to avoid the abnormal sound and excessive wear of the brake assembly 120 and/or the brake disc, the airbag 140 may be provided with an opening 142, and correspondingly provided with a valve 150 for controlling the opening and closing of the opening 142, so that the total amount of gas in the inner cavity of the airbag 140 may be adjusted by the valve 150, the relative position (initial position) between the pump body 110 and the fixing frame 130 may be adjusted by controlling the total amount of gas, and the brake assembly 120 and the brake disc provided on the pump body 110 have a certain gap in a non-braking state by adjusting the position of the pump body 110, so as to avoid the abnormal sound and excessive wear of the brake assembly 120 and/or the brake disc.

The pump body 110 is provided with the sliding sleeve 112, and the sliding sleeve 112 is sleeved on the periphery of the sliding shaft 170, so that the sliding connection between the pump body 110 and the fixed frame 130 is realized, and therefore, the pump body 110 can slide relative to the fixed frame 130 along the axial direction of the sliding shaft 170.

As shown in fig. 1 to 4, the airbag 140 is also sleeved on the outer periphery of the sliding shaft 170, so that the airbag 140 can be supported by the sliding shaft 170, one end of the airbag 140 close to the fixing frame 130 is fixedly connected with the fixing frame 130, the airbag 140 is fixedly connected to the sliding sleeve 112 through the opening 142, and a sealing process is performed at the connection position, so that the inner cavity 141 of the airbag can be communicated with the inner cavity of the sliding sleeve 112 through the opening 142, i.e., the inner cavity 141 of the airbag is communicated with the inner cavity of the sliding sleeve 112, and a valve 150 is disposed at another port of the sliding sleeve 112, so that the total amount of gas in the inner cavity 141 of the airbag can be adjusted by opening or closing the valve 150.

As shown in fig. 1 to 3, in order to improve the stability of the sliding of the pump body 110 relative to the fixed frame 130, a secondary sliding shaft 180 may be further provided, one end of the secondary sliding shaft 180 is fixedly screwed to the fixed frame 130, a secondary sliding sleeve 111 may be correspondingly provided on the pump body 110, and the secondary sliding sleeve 111 is sleeved on the outer circumference of the secondary sliding shaft 180, thereby realizing the relative sliding between the two. Meanwhile, a sub-air bag 160 may be disposed between the sub-sliding sleeve 111 and the fixing frame 130, and the sub-air bag 160 may or may not be provided with the valve 150.

Optionally, as shown in fig. 4, the airbag 140 has a corrugated structure, so that deformation of the airbag 140 can be buffered well through the corrugated structure, and the service life of the airbag 140 can be prolonged.

Alternatively, as shown in fig. 1 to 4, the valve 150 is a screw, and the screw is screwed with the sliding sleeve 112, thereby sealing the inner cavity 141 of the air bag and the inner cavity of the sliding sleeve 112.
