[0028] In the present embodiment, the electronic parking assembly control mechanism for intelligent driving of a vehicle is a vehicle safety control system that replaces conventional manual valves and quick-release valves with an electronic control unit (NCU) and an electronic parking brake system valve assembly with an internal breathing structure, and is combined with other systems and logics. It has the advantages of compact structure and complete functions, and is widely used in intelligent driving of vehicles. However, during the operation of the electronic parking assembly control mechanism for intelligent driving of a vehicle, it is usually necessary to implement different working instructions of the electronic parking assembly control mechanism for intelligent driving of the vehicle by passing fluids through different pathways. Therefore, multiple fluid sources 41 are usually required to realize the normal operation of the electronic parking assembly control mechanism for intelligent driving of the vehicle, resulting in a complex structure of the electronic parking assembly control mechanism for intelligent driving of the vehicle and great control difficulty. The present embodiment provides an electronic parking assembly control mechanism for intelligent driving of a vehicle, such as Figure 5As shown, the control mechanism of the electric parking assembly for intelligent driving of a vehicle may include a distribution component 01 and an adjustment component 02. The distribution component 01 may include a first housing 11, a distribution unit 12, and a first interface unit 13. The distribution unit 12 is detachably connected to the first housing 11. The distribution unit 12 may be arranged in the hollow cavity of the first housing 11. The distribution unit 12 may separate the space surrounded by the first housing 11 into a first space and a second space. The first interface unit 13 may include a first port 131 and a second port 132. The first port 131 and the second port 132 are respectively connected to the first space, so that the fluid can flow between the first port 131 and the second port 132 during the electric parking process. The first port 131 and the second port 132 may be connected to the first housing 11 respectively. The adjustment component 02 may include a second housing 24, a first adjustment unit 21, a second adjustment unit 22, and a second interface unit 25. The second housing 24 may be arranged on the side of the second space away from the first space. The second housing 24 may be connected to the first housing 11. One side of the first regulating unit 21 can be abutted against one side of the second regulating unit 22 to form a fluid chamber, so that the first regulating unit 21 can cooperate with the second regulating unit 22 to control the movement trajectory of the fluid. The first regulating unit 21 and the second regulating unit 22 can be respectively arranged in the space surrounded by the second shell 24. The first regulating unit 21 and the second shell 24 are detachably connected near the first shell 11. The space where the second regulating unit 22 is separated from the second shell 24 away from the first regulating unit 21 is a pressure space, and the fluid can flow into the pressure space from the first port 131, so that the fluid can squeeze the second regulating unit 22, so that the second regulating unit 22 can move in the direction close to the first regulating unit 21, thereby ensuring the sealing between the first regulating unit 21 and the second regulating unit 22. The second interface unit 25 may include a fourth port 251, and in the parking release state, the fluid can flow out through the fourth port 251, and then move from the fourth port 251 to the spring brake cylinder of the trailer, offset the braking force in the brake cylinder, and realize the parking release of the trailer through the fluid. The fourth port 251 is connected to the fluid chamber. The fourth port 251 is connected to the second housing 24. The first port 131 is connected to the pressure space. Figure 5As shown, the second interface unit 25 may also include a fifth port 252 and a sixth port 253. The fifth port 252 may be connected to the second housing 24, the sixth port 253 may be connected to the second housing 24, the fifth port 252 may be connected to the fourth port 251, and the fifth port 252 may be connected to a pressure sensor to monitor the flow through the spring brake cylinder of the trailer by changing the pressure value of the fluid. The sixth port 253 can be connected to the second space, and one end of the sixth port 253 away from the second space can be connected to a manual fluid switch. When the electric parking assembly control mechanism fails, the fluid in the second space can be discharged from the sixth port 253 to the external space of the electric parking assembly control mechanism by operating the manual fluid switch, so that the distribution unit 12 moves to the first port 131 and the connection with the first space is disconnected, and the first space and the third space are connected, so that the fluid in the spring brake cylinder of the tractor can pass through the second port 132, the first space, the third space, and the third port 133 in sequence, and at the same time, the fluid in the spring brake cylinder of the trailer can pass through the fourth port 251, the first space, the third space, and the third port 133 in sequence, thereby realizing the parking brake of the trailer and the tractor.

[0029] In the process of vehicle intelligent driving, Figure 1 As shown, the electric parking assembly control mechanism may include a first working state during the rotation of the second regulating unit 22 around the central axis of the second regulating unit 22. By rotating the second regulating unit 22 around the central axis of the second regulating unit 22, the flow direction of the fluid can be controlled by the first regulating unit 21 and the second regulating unit 22 when the fluid flows through the fluid chamber, so that the electric parking assembly control mechanism can be switched to different working states. The first working state may include the second regulating unit 22 rotating to the first state. Figure 3 As shown, after the first port 131, the fluid chamber, and the second space are connected in sequence, the distribution unit 12 moves to the first space and connects with the first port 131, and then the first port 131, the first space, and the second port 132 are connected in sequence, and the first port 131, the first space, and the fourth port 251 are connected in sequence. That is, the fluid can pass through the first port 131, the chamber, and the second space in sequence, driving the distribution unit 12 to move to the first space and connect with the first port 131, and then the fluid can pass through the first port 131 and the first space to the second port 132 in sequence, and at the same time, the fluid passes through the first port 131 and the first space to the fourth port 251 in sequence, so that in the first working state, part of the fluid can pass through the first port 131 and the first space to the second port 132 in sequence, and then move from the second port 132 to the spring brake cylinder of the tractor to offset the braking force in the brake cylinder, so that during the intelligent driving of the vehicle, the parking release of the tractor can be achieved through the fluid. At the same time, the fluid passes through the first port 131 and the first space to the fourth port 251 in sequence, as shown Figure 2As shown, the fourth port 251 then moves to the spring brake cylinder of the trailer to offset the braking force in the brake cylinder, and the parking release of the trailer is realized through the fluid. The first port 131 can be connected to the pressure space, so that the fluid flowing through the first port 131 can flow into the pressure space, exerting pressure on the second regulating unit 22, so that the second regulating unit 22 is tightly abutted against the first regulating unit 21, ensuring the sealing between the first valve plate 211 and the second valve plate 221. By the fluid from the first port 131 flowing through two paths at the same time, the control mechanism of the electric parking assembly can simultaneously realize the control of the trailer and the tractor and the sealing of the first regulating unit 21 and the second regulating unit 22, thereby realizing the intelligent driving of the vehicle.

[0030] In this embodiment, if Figure 8 , Fig. 9 As shown, the first regulating unit 21 may include a first valve plate 211, an inlet hole 212, a first fluid module 213, a second fluid module 214, and a third hole 215. The inlet hole 212, the first fluid module 213, the second fluid module 214, and the third hole 215 may penetrate both sides of the first valve plate 211 along the thickness direction of the first valve plate 211, so that the fluid can flow from one side of the first valve plate 211 to the other side through the inlet hole 212, the first fluid module 213, the second fluid module 214, and the third hole 215. The inlet hole 212, the first fluid module 213, the third hole 215, and the second fluid module 214 may be arranged in sequence along a set direction around the central axis of the first valve plate 211, and the set direction may be clockwise or counterclockwise. The first valve plate 211 is detachably connected to the second housing 24 near the first housing 11. The first valve plate 211 may be arranged in a space surrounded by the second housing 24.

[0031] like Fig.10 As shown, the second regulating unit 22 may include a second valve plate 221, a fourth slot 222, and a fifth slot 223. One side of the first valve plate 211 abuts against one side of the second valve plate 221 to form a fluid chamber. Fig.11As shown, the other side of the second valve disc is a plane. The second valve disc 221 can be arranged in the space surrounded by the second shell 24. The space between the second valve disc 221 and the second shell 24 on the side away from the first valve disc 211 can be a pressure space. When the fluid enters the pressure space from the first port 131, pressure can be applied to the second valve disc 221, so that the second valve disc 221 can move in the direction close to the first valve disc 211, thereby ensuring the sealing between the first valve disc 211 and the second valve disc 221. The fourth groove 222 and the fifth groove 223 can be recessed from the side of the second valve disc 221 close to the first valve disc 211 to the direction away from the first valve disc 211. The fourth groove 222 and the fifth groove 223 can be spaced apart along a set direction around the central axis of the second valve disc 221. In other embodiments, the adjustment component 02 may further include a sealing portion 26, which is detachably connected to the side of the hollow cavity of the second shell 24 close to the second valve disc 221, such as Figure 7 As shown, the second valve plate 221 is sealed by the sealing portion 26 to ensure the control accuracy of the control mechanism of the electronically controlled parking assembly.

[0032] The first state may include that the inlet hole 212 is connected to the first fluid module 213 through the fourth groove 222, and the second fluid module 214 may be connected to the third hole 215 through the fifth groove 223. The control mechanism of the electric parking assembly may include a first working state during the rotation of the second valve plate 221 around the central axis of the second valve plate 221. The first working state may also include that after the first port 131, the inlet hole 212, the first fluid module 213, and the second space are connected in sequence, the distribution unit 12 moves to the first port 131 and communicates with the first space.
