[0047] In the related art, the setting of the related structure in the brake structure is fixed in direction, so that the brake structure can only adapt to the same type of automobile. For example, the brake structure of the left-hand drive type can only adapt to the driving equipment of the left-hand drive type, and the brake structure of the right-hand drive type can only adapt to the driving equipment of the right-hand drive type, so that the adaptation ability of the brake structure is poor.

[0050] The left end of the first valve body 100 can have a first interface group 110, which is used to communicate with the wheel body brake 420. When the brake device is in the first use state, the high-pressure liquid at the first interface group 110 can enter the wheel body brake 420, so that the wheel body brake 420 contacts the wheel body 410 to provide a braking force for the wheel body 410, so that the wheel body 410 stops rotating or rotates at a reduced speed. The number of the first interface group 110 is not limited, for example, as shown in Figure 3 , the first interface group 110 has four first interfaces, which can respectively communicate with the wheel body brakes 420 of the four wheel bodies 410 of the traveling device.
[0051] The right end of the second valve body 200 can have a second interface group 210, which is used to communicate with the wheel body brake 420. When the brake device is in the second use state, the high-pressure liquid at the second interface group 210 can enter the wheel body brake 420, so that the wheel body brake 420 contacts the wheel body 410 to provide a braking force for the wheel body 410, so that the wheel body 410 stops rotating or rotates at a reduced speed. The number of the second interface group 210 is not limited, for example, as shown in Figure 6 , the second interface group 210 has four second interfaces, which can respectively communicate with the wheel body brakes 420 of the four wheel bodies 410 of the traveling device.
[0052] As shown in Figure 2 , the right end of the first valve body 100 has a third interface group 120; as shown in Figure 5 , the left end of the second valve body 200 has a fourth interface group 220; in some embodiments, the brake device can further include a connecting pipe body and an electromagnetic valve assembly 360 arranged on the connecting pipe body, the electromagnetic valve assembly 360 is electrically connected with the control assembly 330, the electromagnetic valve assembly 360 can be controlled to work through the control assembly 330, and the connecting pipe body can be controlled to be communicated or disconnected through the electromagnetic valve assembly 360; in the first use state, the connecting pipe body communicates with the third interface group 120; in the second use state, the connecting pipe body communicates with the fourth interface group 220. Of course, in other embodiments, the brake device can not be provided with the connecting pipe body and the electromagnetic valve assembly 360; or, the brake device can include a connecting pipe body and a control valve assembly arranged on the connecting pipe body.
[0053] The first valve body 100 is provided with a first group of liquid guide channels 130, and the second valve body 200 is provided with a second group of liquid guide channels 230; in the first use state, the first ends 131 of the first group of liquid guide channels are in communication with the interfaces of the first liquid storage body 321 of the liquid storage assembly 320, the second ends of the first group of liquid guide channels 130 are in communication with the first interface group 110 of the first valve body 100, and the middle sections of the first group of liquid guide channels 130 are guided through the connecting pipe body; in the second use state, the first ends 231 of the second group of liquid guide channels are in communication with the interfaces of the second liquid storage body 322 of the liquid storage assembly 320, the second ends of the second group of liquid guide channels 230 are in communication with the second interface group 210 of the second valve body 200, and the middle sections of the second group of liquid guide channels 230 are guided through the connecting pipe body, so as to control the communication or disconnection of the first group of liquid guide channels 130 and the second group of liquid guide channels 230 through the electromagnetic valve assembly 360 on the connecting pipe body. Of course, in other embodiments, the connecting pipe body can also be arranged at other positions.
[0054] The first valve body 100 and the second valve body 200 can have the same size, so that the volume of the brake device in the first use state and the second use state is basically the same, so that the brake device can be provided with basically the same installation space when the pressure regulating assembly 350 is arranged in different directions on the running equipment, so as to reduce the installation space of the brake device. Of course, in other examples, the first valve body 100 and the second valve body 200 can also have different sizes.
[0055] In the embodiments of the present application, the first valve body 100 and the second valve body 200 can share a liquid storage body or can not share a liquid storage body.
[0056] For example, the liquid storage assembly 320 can include a first liquid storage body 321 and a second liquid storage body 322; in the first use state, the first liquid storage body 321 is connected to the top end of the first valve body 100; in the second use state, the second liquid storage body 322 is connected to the top end of the second valve body 200.
[0057] Here, the first liquid storage body 321 and the second liquid storage body 322 can have the same size, so that the volume of the brake device in the first use state and the second use state is basically the same. Of course, the first liquid storage body 321 and the second liquid storage body 322 can also have different sizes.
[0058] Here, the interface positions of the first liquid storage body 321 and the second valve body 200 and the second liquid storage body 322 and the second valve body 200 can be different, so that the volume of the brake device in the first use state and the second use state is basically the same, and the volume of the brake device is arranged to be smaller. Of course, the interface positions of the first liquid storage body 321 and the first valve body 100 and the second liquid storage body 322 and the second valve body 200 can also be the same.
[0059] Here, the first storage body 321 and the first valve body 100 are connected through a first connecting structure, and the second storage body 322 and the second valve body 200 are connected through a second connecting structure; the first connecting structure and the second connecting structure can be the same or different. For example, the first connecting structure and the second connecting structure are the same, and the first connecting structure and the second connecting structure can both be a buckle structure, a threaded structure, etc. For another example, the first connecting structure and the second connecting structure are different, and one of the first connecting structure and the second connecting structure is a buckle structure, and the other of the first connecting structure and the second connecting structure is a threaded structure.

In the first use state, part of the pressure regulating assembly 350 is arranged in the first pressure regulating cavity 140 through the opening of the first pressure regulating cavity 140, so that the pressure regulating assembly 350 adjusts the pressure of the liquid in the first pressure regulating cavity 140, thereby adjusting the pressure in the first group of liquid guide channels 130. In the second use state, part of the pressure regulating assembly 350 is arranged in the second pressure regulating cavity 240 through the opening of the second pressure regulating cavity 240, so that the pressure regulating assembly 350 adjusts the pressure of the liquid in the second pressure regulating cavity 240, thereby adjusting the pressure in the second group of liquid guide channels 230.
[0061] Of course, in other embodiments, the first pressure regulating cavity 140 can also be arranged outside the first valve body 100, and at this time, the first group of liquid guide channels 130 can be in communication with the first pressure regulating cavity 140 through a pipe body. The second pressure regulating cavity 240 can also be arranged outside the second valve body 200, and at this time, the second group of liquid guide channels 230 can be in communication with the second pressure regulating cavity 240 through a pipe body.
