[0035] It should be noted that the terms "first", "second", "third" involved in the embodiments of the present application are only to distinguish similar objects, and do not represent a specific order of the objects. Understandably, "first", "second", "third" can be interchanged in specific order or sequence as allowed. It should be understood that the objects distinguished by "first", "second", "third" can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.
[0036] The technical solutions of the present application are further described in detail below in combination with the drawings and specific embodiments of the present application. Figures 1 to 8The valve block assembly of the embodiments of the present application is described in detail. It can be understood that the valve block assembly is used in a brake device. In a specific embodiment of the present application, the brake device includes a master cylinder assembly 310, a pressure regulating assembly 350, a reservoir assembly 320 and a control assembly 330. Among them, the control assembly 330 is electrically connected with the pressure regulating assembly 350. The valve block assembly includes a first valve body 100 and a second valve body 200, and the first valve body 100 and the second valve body 200 are arranged separately. Specifically, in some embodiments, the first valve body 100 in the valve block assembly can be selected for assembly brake. In other embodiments, the second valve body 200 in the valve block assembly can be selected for assembly brake, and the specific selection can be determined according to the actual situation.
[0037] It should be noted that the valve block assembly has a first working state and a second working state. Referring to Figure 1 In the first working state, the master cylinder assembly 310 can be connected with the first end of the first valve body 100, the pressure regulating assembly 350 can be connected with the left end of the first valve body 100, the control assembly 330 can be connected with the right end of the first valve body 100, and the reservoir assembly 320 can be connected with the top end of the first valve body 100. Referring to Figure 4 In the second working state, the master cylinder assembly 310 can be connected with the first end of the second valve body 200, the pressure regulating assembly 350 can be connected with the right end of the second valve body 200, the control assembly 330 can be connected with the left end of the second valve body 200, and the reservoir assembly 320 can be connected with the top end of the second valve body 200.
[0038] It can be understood that the brake structure can brake the running equipment such as vehicle, and the brake structure includes valve block, master cylinder assembly 310, pressure regulating assembly 350, reservoir assembly 320 and control assembly 330. The valve block as the main mechanical part in the brake structure, through the internal oil circuit, can connect the master cylinder assembly 310, the pressure regulating assembly 350, the reservoir assembly 320 and the motor structure to realize brake. In the related art, the motor structure can only be arranged on one side relative to the valve block, when the motor needs to be replaced to adapt to the left or right steering running equipment, the valve block, the control assembly and the reservoir assembly need to be redeveloped, resulting in high production cost of the brake structure.
[0039] In the first operating state, the valve block assembly of this application has the master cylinder assembly 310 connected to the first end of the first valve body 100, the pressure regulating assembly 350 connected to the left end of the first valve body 100, the control assembly 330 connected to the right end of the first valve body 100, and the reservoir assembly 320 connected to the top end of the first valve body 100. This means the braking device can be adapted to a driving device with the pressure regulating structure on the left. In the second operating state, the master cylinder assembly 310 is connected to the first end of the second valve body 200, the pressure regulating assembly 350 is connected to the right end of the second valve body 200, the control assembly 330 is connected to the left end of the second valve body 200, and the reservoir assembly 320 is connected to the top end of the second valve body 200. This means the braking device can be adapted to a driving device with the pressure regulating structure on the right. Therefore, the valve block assembly of this application includes a first valve body 100 and a second valve body 200, and the valve block assembly has a first operating state and a second operating state. Compared to solutions where the valve block can only be adapted to a single installation scenario, this solution allows the braking device to be adapted to both left-hand and right-hand drive vehicles, effectively improving the compatibility of the valve block assembly and avoiding the need for secondary development of the control component 330 and the reservoir component 320, thus saving production costs. Furthermore, compared to solutions where a single valve block is compatible with both left-hand and right-hand drive vehicles, this solution features a thinner valve body, which optimizes the internal space layout of the braking device and reduces the overall volume occupied by the braking device.
[0040] In the embodiments of this application, for ease of description and understanding, the following definitions are used: Figures 1 to 6 The arrows indicate directions, with L and R forming a pair of opposite directions, L pointing to the left and R to the right. T and B forming a pair of opposite directions, T pointing to the top and R to the bottom. It should be noted that left, right, top, and bottom here refer to the approximate directions with the driver on the driving equipment as a reference when the braking device is installed on the driving equipment; that is, when the braking device is installed on the driving equipment, the driver on the driving equipment is used as a reference. In the first operating state, the pressure regulating component 350 is generally located on the left side of the first valve body 100, the control component 330 is generally located on the right side of the first valve body 100, and the reservoir component 320 is generally located on the top side of the first valve body 100; in the second operating state, the pressure regulating component 350 is generally located on the right side of the second valve body 200, the control component 330 is generally located on the left side of the second valve body 200, and the reservoir component 320 is generally located on the top side of the second valve body 200.
[0041] The specific configuration of the valve body assembly is introduced as follows. To facilitate the understanding and comparison of the outer contour of the first valve body 100 and the second valve body 200, a plane perpendicular to the central axis of the first valve body 100 is defined as a first projection plane, which can be understood as being parallel to the side wall surface of the valve body. In the direction parallel to the central axis of the first valve body 100, the first valve body 100 can form a first orthographic projection on the first projection plane, and the second valve body 200 can form a second orthographic projection on the first projection plane. The first orthographic projection coincides with the second orthographic projection, that is, the outer contour of the first valve body 100 is the same as that of the second valve body 200, so that the volume of the brake device in the first working state and the second working state is substantially the same. That is, when the pressure regulating assembly 350 is arranged in different directions on the running equipment, the brake device can be provided with substantially the same installation space, so as to reduce the installation space of the brake device. It should be noted that in other embodiments, the first orthographic projection formed by the first valve body 100 can also be spaced apart from or partially coincided with the second orthographic projection formed by the second valve body 200, that is, the outer contour of the first valve body 100 and the second valve body 200 can also be different.
[0042] It should be noted that in the embodiments of the present application, the interface position of the first valve body 100 and the interface position of the second valve body 200 are different, so that the pressure regulating assembly 350 and the control assembly 330 are arranged in different directions of the first valve body 100 and the second valve body 200.
[0043] The specific configuration of the liquid storage assembly 320 is introduced as follows. In some embodiments, the liquid storage assembly 320 includes a first liquid storage body 321 and a second liquid storage body 322, which are arranged separately. Specifically, in some embodiments, the first liquid storage body 321 of the liquid storage assembly 320 can be selected for assembly and use. In other embodiments, the second liquid storage body 322 of the liquid storage assembly 320 can be selected for assembly and use. In other embodiments, the first valve body 100 and the second valve body 200 can also share one liquid storage body, or can not share one liquid storage body, and the specific configuration can be determined according to the actual situation. It should be noted that when the valve block assembly is in the first working state, the first liquid storage body 321 can be connected to the top end of the first valve body 100; and when the valve block assembly is in the second working state, the second liquid storage body 322 can be connected to the top end of the second valve body 200.
[0044] To facilitate understanding and comparison of the outer shape of the first liquid storage 321 and the second liquid storage 322, a plane perpendicular to the central axis of the first liquid storage 321 is defined as a second projection plane. It can be understood that the second projection plane can be parallel to the side wall surface of the liquid storage. In the direction parallel to the central axis of the first liquid storage 321, the first liquid storage 321 can form a third orthographic projection on the second projection plane, and the second liquid storage 322 can form a fourth orthographic projection on the second projection plane. The third orthographic projection can coincide with the fourth orthographic projection, that is, the outer shape of the first liquid storage 321 can be the same as the outer shape of the second liquid storage 322, so that the volume of the brake device in the first working state and the second working state is substantially the same. It should be noted that in other embodiments, the outer shape of the first liquid storage 321 can also be different from the second liquid storage 322.
[0045] In some embodiments, the interface position of the first liquid storage 321 and the first valve body 100 and the interface position of the second liquid storage 322 and the second valve body 200 can be different, so that the volume of the brake device in the first working state and the second working state is substantially the same, and the volume of the brake device is set to be smaller. Of course, the interface position of the first liquid storage 321 and the first valve body 100 and the interface position of the second liquid storage 322 and the second valve body 200 can also be the same.
[0046] It should be noted that the first liquid storage 321 and the first valve body 100 can be connected through a first connecting structure, and the second liquid storage 322 and the second valve body 200 can be 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 be buckle structures, threaded structures, etc. For example, the first connecting structure and the second connecting structure are different, 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.
[0047] In some embodiments, the left end of the first valve body 100 has a first interface group 110, which is used to communicate with the wheel body brake 420. When the brake device is in the first working state, the high-pressure liquid at the first interface group 110 can enter the wheel body brake 420 to make the wheel body brake 420 contact 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 FIG. 1, 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. Figure 3
[0048] In some embodiments, the right end of the second valve body 200 has a second interface group 210, which is used to communicate with the wheel body brake 420. When the braking device is in the second working 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 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.
[0049] Referring to Figure 2 , the right end of the first valve body 100 has a third interface group 120. Referring to Figure 5 , the left end of the second valve body 200 has a fourth interface group 220. In some embodiments, the braking device further includes 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, so that 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 working state, the connecting pipe body communicates with the third interface group 120. In the second working state, the connecting pipe body communicates with the fourth interface group 220. In other embodiments, the braking device can also not be provided with the connecting pipe body and the electromagnetic valve assembly 360. In other embodiments, the braking device includes a connecting pipe body and a control valve assembly arranged on the connecting pipe body.
[0050] In some embodiments, 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 working state, the first end 131 of the first group of liquid guide channels 130 communicates with the interface of the first liquid storage body 321 of the liquid storage assembly 320, the second end of the first group of liquid guide channels 130 communicates with the first interface group 110 of the first valve body 100, and the middle section of the first group of liquid guide channels 130 is guided to communicate through the connecting pipe body. In the second working state, the first end 231 of the second group of liquid guide channels 230 communicates with the interface of the second liquid storage body 322 of the liquid storage assembly 320, the second end of the second group of liquid guide channels 230 communicates with the second interface group 210 of the second valve body 200, and the middle section of the second group of liquid guide channels 230 is guided to communicate through the connecting pipe body, so that the communication or disconnection of the first group of liquid guide channels 130 and the second group of liquid guide channels 230 is controlled through the electromagnetic valve assembly 360 on the connecting pipe body. In other embodiments, the connecting pipe body can also be arranged at other positions.
[0051] In some optional implementation manners of the embodiments of the present application, referring to Figure 3The first valve body 100 has a first pressure regulating chamber 140, and the opening of the first pressure regulating chamber 140 is located at the left end of the first valve body 100. The first pressure regulating chamber 140 is in communication with the first group of liquid guide channels 130 in the first valve body 100. Referring to Figure 6 The second valve body 200 has a second pressure regulating chamber 240, and the opening of the second pressure regulating chamber 240 is located at the right end of the second valve body 200. The second pressure regulating chamber 240 is in communication with the second group of liquid guide channels 230 in the second valve body 200. In the first working state, part of the pressure regulating assembly 350 is arranged in the first pressure regulating chamber 140 through the opening of the first pressure regulating chamber 140, so that the pressure regulating assembly 350 adjusts the pressure of the liquid in the first pressure regulating chamber 140, thereby adjusting the pressure in the first group of liquid guide channels 130. In the second working state, part of the pressure regulating assembly 350 is arranged in the second pressure regulating chamber 240 through the opening of the second pressure regulating chamber 240, so that the pressure regulating assembly 350 adjusts the pressure of the liquid in the second pressure regulating chamber 240, thereby adjusting the pressure in the second group of liquid guide channels 230.
[0052] In some embodiments, the first pressure regulating chamber 140 can also be arranged outside the first valve body 100, and the first group of liquid guide channels 130 can be in communication with the first pressure regulating chamber 140 through a pipe. The second pressure regulating chamber 240 can also be arranged outside the second valve body 200, and the second group of liquid guide channels 230 can be in communication with the second pressure regulating chamber 240 through a pipe.
[0053] It should be noted that the structure of the pressure regulating assembly 350 is not limited. For example, the pressure regulating assembly 350 can include a hydraulic pump body. The pressure of the first pressure regulating chamber 140 is adjusted by the hydraulic pump body. For another example, the pressure regulating assembly 350 can include a pressure regulating piston, a ball screw, and a motor, wherein the ball screw is connected with the output shaft of the motor and the pressure regulating piston respectively; in the first working state, the pressure regulating piston is located in the first pressure regulating chamber 140 through the opening of the first pressure regulating chamber 140. In the second working state, the pressure regulating piston is located in the second pressure regulating chamber 240 through the opening of the second pressure regulating chamber 240. When the motor rotates, the motor drives the ball screw to rotate through the output shaft of the motor, and the ball screw drives the pressure regulating piston to move in the first pressure regulating chamber 140 or the second pressure regulating chamber 240, thereby adjusting the pressure of the liquid in the first pressure regulating chamber 140 or the second pressure regulating chamber 240. It can be understood that the motor can be a hollow motor or a solid motor, etc.
[0054] In some optional implementations of the embodiments of the present application, the first valve body 100 has a first main cylinder cavity 150, and the opening of the first main cylinder cavity 150 is located at the first end of the first valve body 100. The first main cylinder cavity 150 is in communication with the first group of liquid guide channels 130 in the first valve body 100.
