Description

Technical Field

[0002] With the rapid development of automotive electronic technology, the application of intelligent driving has become increasingly widespread. The electronic parking brake system is an automotive safety control system that replaces the conventional manual control valve and quick release valve with an electronic control unit (NCU) and an electronic parking brake system valve assembly with an internal breathing structure, and combines other systems and logics, having the advantages of compact structure and complete functions. The electronically controlled parking assembly control mechanism for intelligent driving of vehicles usually controls the actuator through a distribution valve after receiving a parking instruction, so as to achieve parking and release actions and realize intelligent driving of the vehicle.

[0061] In this embodiment, the electronic control parking assembly control mechanism for vehicle intelligent driving is an automotive safety control system that changes the conventional manual control valve and quick release valve into an electronic control unit (NCU) and an electronic parking brake system valve assembly with an internal breathing structure, and combines other systems and logics, having the advantages of compact structure and complete functions, and has a very wide application in vehicle intelligent driving. However, during the working process of the electronic control parking assembly control mechanism for vehicle intelligent driving, it is usually necessary to flow fluids through different passages to implement different working instructions of the electronic control parking assembly control mechanism for vehicle intelligent driving. Therefore, usually multiple fluid sources 41 are required to realize the normal operation of the electronic control parking assembly control mechanism for vehicle intelligent driving, resulting in a complex structure and large control difficulty of the electronic control parking assembly control mechanism for vehicle intelligent driving. This embodiment provides an electronic control parking assembly control mechanism for vehicle intelligent driving, such as Figure 5As shown in the figure, the electronically controlled parking assembly control mechanism for vehicle intelligent driving 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 disposed in the hollow cavity of the first housing 11. The distribution unit 12 may divide 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 in communication with the first space, so that during the electronically controlled parking process, the fluid can flow between the first port 131 and the second port 132. The first port 131 and the second port 132 may be respectively connected to the first housing 11. 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 disposed 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 adjustment unit 21 may abut against one side of the second adjustment unit 22 to enclose a fluid chamber, so that the first adjustment unit 21 can cooperate with the second adjustment unit 22 to control the movement trajectory of the fluid. The first adjustment unit 21 and the second adjustment unit 22 may be respectively disposed in the space surrounded by the second housing 24. The first adjustment unit 21 is detachably connected to the side of the second housing 24 close to the first housing 11. The space between the side of the second adjustment unit 22 away from the first adjustment unit 21 and the second housing 24 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 adjustment unit 22, causing the second adjustment unit 22 to move in the direction close to the first adjustment unit 21, thereby ensuring the sealing between the first adjustment unit 21 and the second adjustment unit 22. The second interface unit 25 may include a fourth port 251. When the parking release state is reached, 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 to offset the braking force in the brake cylinder, and the parking release of the trailer is achieved through the fluid. The fourth port 251 is in communication with the fluid chamber. The fourth port 251 is connected to the second housing 24. The first port 131 is in communication with the pressure space. In some other embodiments, such as Figure 5As shown, the second interface unit 25 may further include a fifth port 252 and a sixth port 253. The fifth port 252 may be connected to the second housing 24, and the sixth port 253 may be connected to the second housing 24. The fifth port 252 may communicate with the fourth port 251, and the fifth port 252 may communicate with a pressure sensor. The flow rate of the spring brake cylinder of the trailer is monitored by the change in the pressure value of the fluid. The sixth port 253 may communicate with the second space. One end of the sixth port 253 away from the second space may be connected to a manual fluid switch. When the control mechanism of the electronic parking assembly fails, the fluid in the second space can be discharged from the sixth port 253 to the external space of the control mechanism of the electronic parking assembly by operating the manual fluid switch, so that the communication between the distribution unit 12 and the first port 131 and the first space is disconnected, and the first space and the third space are communicated, so that the fluid in the spring brake cylinder of the tractor can sequentially pass through the second port 132, the first space, the third space, and the third port 133. At the same time, the fluid in the spring brake cylinder of the trailer can sequentially pass through the fourth port 251, the first space, the third space, and the third port 133, so as to realize the parking brake of the trailer and the tractor.

[0062] During the intelligent driving of the vehicle, such as Figure 1 As shown, during the rotation of the second adjustment unit 22 around the central axis of the second adjustment unit 22, the control mechanism of the electronic parking assembly may include a first working state. By rotating the second adjustment unit 22 around the central axis of the second adjustment unit 22, when the fluid flows through the fluid chamber, the flow direction of the fluid can be controlled by the first adjustment unit 21 and the second adjustment unit 22, so that the control mechanism of the electronic parking assembly can switch to different working states. The first working state may include the second adjustment unit 22 rotating to the first state. As Figure 3 As shown, after the first port 131, the fluid chamber, and the second space are sequentially communicated, the distribution unit 12 moves to communicate with the first space and the first port 131, and then the first port 131, the first space, and the second port 132 are sequentially communicated, and the first port 131, the first space, and the fourth port 251 are sequentially communicated. That is, the fluid can sequentially pass through the first port 131, the chamber, and the second space, drive the distribution unit 12 to move to communicate with the first space and the first port 131, and then the fluid can sequentially pass through the first port 131 and the first space to move to the second port 132. At the same time, the fluid sequentially passes through the first port 131 and the first space to move to the fourth port 251. When in the first working state, part of the fluid can sequentially pass through the first port 131 and the first space to move to the second port 132, 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 realized through the fluid. At the same time, the fluid sequentially passes through the first port 131 and the first space to move to the fourth port 251. As Figure 2As shown, it then moves from the fourth port 251 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 achieved through the fluid. The first port 131 can be in communication with the pressure space, so that the fluid flowing through the first port 131 can flow into the pressure space to apply pressure to the second regulating unit 22, thereby making the second regulating unit 22 in close contact with the first regulating unit 21 to ensure the sealing between the first valve plate 211 and the second valve plate 221. By making the fluid from the first port 131 flow through two paths simultaneously, the electronically controlled parking assembly control mechanism can simultaneously control the trailer and the tractor and seal the first regulating unit 21 and the second regulating unit 22, thus realizing the intelligent driving of the vehicle.

[0063] In this embodiment, as Figure 8 、 Figure 9 shown, the first regulating unit 21 can include a first valve plate 211, an inflow hole 212, a first fluid module 213, a second fluid module 214, and a third hole 215. The inflow hole 212, the first fluid module 213, the second fluid module 214, and the third hole 215 can penetrate through 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 inflow hole 212, the first fluid module 213, the second fluid module 214, and the third hole 215. The inflow hole 212, the first fluid module 213, the third hole 215, and the second fluid module 214 can be sequentially arranged at intervals around the central axis of the first valve plate 211 in a set direction, and the set direction can 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 can be arranged in the space surrounded by the second housing 24.

[0064] As Figure 10 shown, the second regulating unit 22 can include a second valve plate 221, a fourth groove 222, and a fifth groove 223. A fluid chamber is formed by the abutting and surrounding of one side of the first valve plate 211 and one side of the second valve plate 221. As Figure 11As shown, the other side of the second valve plate is a flat surface. The second valve plate 221 can be disposed in the space surrounded by the second housing 24. The space between the side of the second valve plate 221 away from the first valve plate 211 and the second housing 24 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 plate 221, so that the second valve plate 221 can move in the direction close to the first valve plate 211, ensuring the sealing performance between the first valve plate 211 and the second valve plate 221. The fourth groove 222 and the fifth groove 223 can be recessed from the side of the second valve plate 221 close to the first valve plate 211 in the direction away from the first valve plate 211. The fourth groove 222 and the fifth groove 223 can be arranged at intervals along the set direction around the central axis of the second valve plate 221. In some other embodiments, the adjusting assembly 02 can further include a sealing portion 26, and the sealing portion 26 is detachably connected to the side close to the second valve plate 221 in the hollow cavity of the second housing 24, such as Figure 7 shown, the second valve plate 221 is sealed by the sealing portion 26 to ensure the control accuracy of the control mechanism of the electronic parking assembly.

When in the first working state, part of the fluid may sequentially pass through the first port 131 and the first space and move to the second port 132, 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 sequentially passes through the first port 131, the first space, the third hole 215, the fifth groove 223, and the second fluid module 214 and moves to the fourth port 251, and then moves from the second port 132 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 achieved through the fluid.

When the fluid flows out from the third port 133, the second distribution unit 12 will move in the direction close to the second valve plate 221, so that the third chamber can be communicated with the third port 133, and the fluid can flow out from the third port 133, thereby realizing the parking of the tractor.

[0083] In this embodiment, the first adjusting unit 21 may further include a fourth hole 216.
