Description

Technical Field

[0001] This application relates to the field of automotive transmission system technology, and in particular to a ventilation structure for an intelligent transmission system. Background Technology

[0002] With the continued acceleration of urbanization, urban flooding is becoming increasingly severe. Against this backdrop, vehicles are encountering flooded conditions more frequently, leading to increasingly stringent requirements on the wading depth of their entire transmission system. In other words, vehicle transmission systems need to possess stronger wading capabilities to ensure normal operation on urban roads with deep floodwaters.

[0003] However, at the same time, as society's demands for vehicle range gradually increase, the requirements for the sealing system's clamping force are decreasing to reduce the impact of factors such as energy loss. This is because a smaller clamping force helps reduce friction and other resistance, thereby improving the vehicle's range performance. But this situation also raises new issues, namely, the selection of the transmission system's ventilation structure has become more stringent.

[0004] In existing venting structures, the normally open membrane structure has significant drawbacks when used in oil chambers. Due to the presence of oil and gas in the oil chamber, the normally open membrane is easily clogged, losing its venting function and ultimately causing the entire venting structure to fail. One-way valves also face a dilemma. When the opening pressure of the one-way valve is low, it cannot meet the wading depth requirements of the vehicle's transmission system and is unable to withstand the pressure of accumulated water; when the opening pressure of the one-way valve is high, the sealing structure cannot meet the system's sealing requirements, potentially leading to leakage and other problems.

[0005] In summary, there is an urgent need for a smartly opening ventilated structure to solve the aforementioned complex problems and meet the vehicle's requirements for ventilation and sealing of the transmission system under different operating conditions. Utility Model Content The purpose of this application is to provide a ventilation structure for an intelligent transmission system to solve at least one of the technical problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, this application provides a ventilation structure for an intelligent transmission system, characterized in that it includes a housing; The housing contains a transmission system oil chamber, a control structure, and a ventilation structure. The transmission system oil chamber is indirectly connected to the ventilation structure through the control structure; The ventilation structure includes a ventilation valve and an intake valve disposed on the housing; The vent valve only allows the medium to flow unidirectionally from the inside of the housing to the outside, preventing the external medium from flowing back into the transmission system oil chamber. The intake valve remains open under normal conditions; The control structure is used to adjust the on / off state of the transmission system oil chamber and the vent valve and the intake valve according to the pressure change in the transmission system oil chamber.

[0007] Furthermore, the inner wall of the transmission system oil chamber near the control structure is provided with a through-hole that connects to the control structure, and is used to guide the medium in the transmission system oil chamber to the control structure.

[0008] Furthermore, the control structure includes a control cavity, a control lever, and an end control assembly; The control cavity is located inside the housing and is connected to the communication port; The control rod is slidably disposed within the control cavity; The control cavity has a closed end at one axially upward end and the end control component is sealed and connected to the other end. The end control component is used to adjust the displacement stroke of the control lever, thereby controlling the connection status between the transmission system oil chamber and the vent valve and intake valve.

[0009] Furthermore, the control lever includes a guide lever area and a flow lever area; The outer periphery of the guide rod area slides against the inner wall of the control cavity to ensure sealing and movement stability. The diameter of the flow rod area is smaller than that of the guide rod area, thereby forming an annular gap between the flow rod area and the inner wall of the control cavity, which serves as a medium flow channel.

[0010] Furthermore, the axial length of the flow rod area is less than the distance between the vent valve and the intake valve, so as to ensure that the transmission system oil chamber can be independently connected to the vent valve or the intake valve during the movement of the control rod, avoiding simultaneous conduction and causing the medium flow direction to be chaotic.

[0011] Furthermore, the end control assembly includes an electromagnetic controller and an elastic element; The control rod is made of magnetic material or has a magnetic attraction component that can be attracted by magnetism. The electromagnetic controller is fixedly installed at the end of the control cavity and is used to drive the control rod to move axially through an electromagnetic field. One end of the elastic element abuts against the end of the control rod near the electromagnetic controller, and the other end abuts against the electromagnetic controller; The elastic element is always in a compressed state, tending to push the control rod away from the electromagnetic controller, and keeping the control rod in contact with the closed end of the control cavity in the initial position.

[0012] Furthermore, it also includes a control processor; A pressure sensor is installed in the oil chamber of the transmission system; The control processor is electrically connected to the pressure sensor and the electromagnetic controller; The pressure sensor monitors the pressure changes in the oil chamber of the transmission system in real time and transmits the pressure signal to the control processor. The control processor automatically or manually determines the current working condition based on the received pressure signal, and then automatically or manually controls the power-on / off state of the electromagnetic controller.

[0013] Furthermore, the electromagnetic controller is an electromagnetic coil component, which generates a magnetic field when energized, attracting the control rod to move towards the electromagnetic controller against the elastic force of the elastic element.

[0014] Furthermore, the elastic element is a compression spring.

[0015] Furthermore, the vent valve is a one-way valve structure, and the intake valve is a normally open valve structure. Attached Figure Description

[0023] The present application will be further explained below with reference to specific implementation methods.

[0024] Example 1 like Figure 1-3 As shown, the intelligent transmission system ventilation structure 4 provided in this embodiment includes a housing 1; The housing 1 is provided with a transmission system oil chamber 2, a control structure 3 and a ventilation structure 4; The transmission system oil chamber 2 is indirectly connected to the ventilation structure 4 through the control structure 3; The ventilation structure 4 includes a ventilation valve 5 and an air intake valve 6 disposed on the housing 1; The vent valve 5 only allows the medium to flow unidirectionally from the inside of the housing 1 to the outside, preventing the external medium from flowing back into the transmission system oil chamber 2. The intake valve 6 remains open under normal conditions; The control structure 3 is used to adjust the on / off state of the transmission system oil chamber 2 and the vent valve 5 and the intake valve 6 according to the pressure change in the transmission system oil chamber 2.

[0025] The intelligent transmission system ventilation structure 4 disclosed in this application aims to effectively solve the problem that traditional ventilation structures 4 are difficult to balance sealing and ventilation efficiency under complex working conditions. By controlling the structure 3 to sense the pressure change in the oil chamber in real time, the ventilation valve 5 is opened to exhaust when the pressure is positive, and the ventilation valve 5 is closed when the pressure is negative and the outside air is introduced by the intake valve 6, thereby maintaining the internal pressure balance.

[0026] As a further embodiment of this example, the inner wall of the transmission system oil chamber 2 near the control structure 3 is provided with a through-hole 7 that penetrates the inner wall. The through-hole 7 is connected to the control structure 3 and is used to guide the medium in the transmission system oil chamber 2 to the control structure 3.

[0027] As a further embodiment of this example, the control structure 3 includes a control cavity 8, a control rod 9, and an end control assembly 10; The control cavity 8 is located inside the housing 1 and is connected to the communication port 7; The control rod 9 is slidably disposed within the control cavity 8; The control cavity 8 has a closed end 11 at one axially upward end, and the end control assembly 10 is sealed and connected to the other end. The end control component 10 is used to adjust the displacement stroke of the control lever 9, thereby controlling the connection state between the transmission system oil chamber 2 and the vent valve 5 and the intake valve 6.

[0028] As a further embodiment of this example, the control lever 9 includes a guide lever area 12 and a flow lever area 13; The outer periphery of the guide rod area 12 slides against the inner wall of the control cavity 8 to ensure sealing and movement stability. The diameter of the flow rod area 13 is smaller than that of the guide rod area 12, thereby forming an annular gap between the flow rod area 13 and the inner wall of the control cavity 8, which serves as a medium flow channel.

[0029] As a further embodiment of this embodiment, the axial length of the flow rod area 13 is less than the distance between the vent valve 5 and the intake valve 6, so as to ensure that during the movement of the control rod 9, the transmission system oil chamber 2 can be independently connected to the vent valve 5 or the intake valve 6, avoiding simultaneous connection and causing the medium flow direction to be chaotic.

[0030] In this application, oil and gas inevitably generate during the operation of the transmission system due to temperature changes and pressure fluctuations. The ventilation structure 4 precisely regulates the gas flow path through the displacement of the control rod 9. Under normal conditions, the control rod 9 abuts against the closed end 11. At this time, the flow rod area 13 connects the ventilation valve 5 and the connecting port 7, while the guide rod area 12 completely blocks the intake valve 6, achieving unidirectional exhaust function. When the pressure inside the oil chamber decreases, forming a negative pressure, the end control component 10 drives the control rod 9 to move to the end. The flow rod area 13 blocks the ventilation valve 5 and connects the intake valve 6 and the connecting port 7. Outside air enters the oil chamber through the intake valve 6, and the membrane structure filters out only air molecules, effectively preventing moisture intrusion and ensuring the cleanliness and pressure balance inside the oil chamber. This ventilation structure 4 achieves precise switching between exhaust and intake by dynamically responding to the pressure difference inside and outside the oil chamber. This not only avoids the problems of easy clogging and water ingress in traditional respirators but also significantly improves the system's adaptability under frequent temperature changes.

[0031] As a further embodiment of this embodiment, the end control component 10 includes an electromagnetic controller 14 and an elastic element 15; The control lever 9 is made of magnetic material or is provided with a magnetic attraction component that can be attracted by magnetism; The electromagnetic controller 14 is fixedly installed at the end of the control cavity 8 and is used to drive the control rod 9 to move axially through an electromagnetic field. One end of the elastic element 15 abuts against the end of the control rod 9 near the electromagnetic controller 14, and the other end abuts against the electromagnetic controller 14; The elastic element 15 is always in a compressed state, tending to push the control rod 9 away from the electromagnetic controller 14, and keeping the control rod 9 in contact with the closed end 11 of the control cavity 8 in the initial position.

[0032] As a further embodiment of this invention, a control processor 16 is also included; A pressure sensor 17 is installed in the oil chamber 2 of the transmission system; The control processor 16 is electrically connected to the pressure sensor 17 and the electromagnetic controller 14; The pressure sensor 17 monitors the pressure changes in the oil chamber 2 of the transmission system in real time and transmits the pressure signal to the control processor 16; The control processor 16 automatically or manually determines the current working condition based on the received pressure signal, thereby automatically or manually controlling the power on / off state of the electromagnetic controller 14.

[0033] In a preferred embodiment of this invention, the electromagnetic controller 14 is an electromagnetic coil component that generates a magnetic field when energized, attracting the control rod 9 to move toward the electromagnetic controller 14 against the elastic force of the elastic element 15.

[0034] In a preferred embodiment of this invention, the elastic element 15 is a compression spring.

[0035] In the ventilation phase of the venting structure 4 disclosed in this application, the pressure sensor 17 detects that the pressure inside the oil chamber has risen to a set threshold. The control processor 16 determines that it is in the venting condition and immediately controls the solenoid coil to be de-energized. The compression spring pushes the control rod 9 back to its initial state. At this time, the flow rod area 13 of the control rod 9 connects the venting valve 5 to the connecting port 7, while the guide rod area 12 blocks the intake valve 6, thus realizing the discharge of oil and gas. Under normal circumstances, the opening pressure of the venting valve 5 is 5-10 kPa, and the low-friction oil seal can withstand a positive pressure of Min15 kPa, thus ensuring the normal operation of the low-friction oil seal. In this state, since the one-way venting valve 5 is working, it will only open when there is pressure in the chamber and the pressure reaches the opening pressure of the one-way venting valve 5, thus discharging the oil and gas from the oil chamber and preventing the pressure inside the chamber from rising again. When this state is entered into water, the temperature of the oil chamber drops, and the pressure inside the oil chamber will also drop with the temperature drop, and the one-way venting valve 5 will be in the closed state.

[0036] The working principle of the ventilation structure 4 disclosed in this application during the intake phase is as follows: To ensure the pressure balance inside and outside the chamber, when the temperature inside the oil chamber drops, the pressure inside the chamber also drops. At this time, due to the previous exhaust, a negative pressure will be generated inside the chamber. When the pressure sensor 17 detects that the pressure inside the chamber is lower than the set threshold, the control processor 16 determines that it is in the intake condition and then controls the electromagnetic coil to be energized, generating a magnetic field that attracts the control rod 9 to move against the spring force, so that the intake valve 6 and the connecting port 7 are connected and opened while the ventilation valve 5 is closed. At this time, external air enters the transmission system oil chamber 2 through the normally open valve. Since the normally open valve adopts a selectively permeable membrane structure, it only allows air molecules to pass through while blocking water molecules, effectively avoiding the risk of water ingress. As air continues to be replenished, the pressure inside the oil chamber gradually rises back to the equilibrium state, ensuring that the internal components are not affected by the negative pressure. When the pressure returns to the set range, the control processor 16 cuts off the power supply to the electromagnetic coil, the control rod 9 is reset under the action of the spring, the intake channel is closed, and the system returns to the initial standby state. The whole process realizes the organic unity of automatic sensing, accurate response and safe ventilation.

[0037] The venting structure 4 disclosed in this application monitors the pressure difference inside and outside the oil chamber in real time through a pressure sensor 17, and intelligently controls the on / off state of the electromagnetic coil through a control processor 16 to achieve precise switching between intake and exhaust conditions. During high-temperature exhaust, a one-way valve automatically opens to release oil and gas, preventing pressure buildup; in low-temperature or water-immersion environments, it actively replenishes air to prevent negative pressure from causing seal failure. The entire process requires no manual intervention, is highly responsive and reliable, and effectively improves the sealing stability and service life of the transmission system under complex operating conditions.

[0038] like Figure 4-5 As shown, as a further embodiment of this example, the vent valve 5 is a one-way valve structure, and the intake valve 6 is a normally open valve structure.

[0039] In this application, the vent valve 5 adopts a one-way valve structure, which only allows gas in the oil chamber to be discharged outward, preventing external contaminants from entering in the reverse direction. This one-way valve is open in one direction and has an inverted U-shaped design inside. When the vehicle is wading through water, the water pressure compresses the air, and the liquid level cannot exceed the top of the inverted U, thereby blocking the water flow into the cavity channel; after leaving the water area, the remaining water is discharged naturally through the vent hole.

[0040] In this application, the air intake valve 6 adopts a normally open valve structure, the core of which is a selectively permeable membrane that allows only air molecules to pass through while blocking liquid water and impurities from entering the cavity. This design greatly improves water safety and environmental adaptability while achieving continuous pressure compensation.

[0041] like Figure 4 As shown, as a further embodiment of this example, the vent valve 5 includes a valve body 18 and a valve cap 19; The valve body 18 is disposed on the housing 1 below; The valve cap 19 is disposed on the side of the valve body 18 away from the housing 1; The vent valve 5 is provided with a first channel 20, a second channel 21, a third channel 22 and a fourth channel 23; The lower end of the first channel 20 extends into the housing 1, and the upper end of the first channel 20 is connected to the lower end of the second channel 21; The upper end of the second channel 21 is connected to one end of the third channel 22; The third channel 22 is formed by the valve body 18 and the valve cap 19; The other end of the third channel 22 is connected to the fourth channel 23; The end of the fourth channel 23 that is away from the third channel 22 is connected to the outside air.

[0042] As a further embodiment of this embodiment, a clamping block 24 and a clamping spring 25 are provided in the second channel 21; The clamping block 24 is disposed at one end of the second channel 21 that connects to the first channel 20; The upper end of the compression spring 25 abuts against the valve cap 19, and the lower end abuts against the compression block 24; The valve body 18 is provided with a limiting part 26 for abutting against the edge of the valve cap 19; The compression spring 25 is always in a compressed state, tending to lift the valve cap 19 upwards, while the edge of the valve cap 19 will not detach due to the limiting part 26, and ensuring that the third channel 22 formed between the valve body 18 and the valve cap 19 remains unobstructed.

[0043] When the air pressure at the first channel 20 increases, the gas pushes the clamping block 24 to compress the clamping spring 25. The gas enters the second channel 21 along the first channel 20 and is discharged to the outside through the third channel 22 and the fourth channel 23.

[0044] As a further embodiment of this embodiment, the vent valve 5 also includes a first sealing ring 27 and a second sealing ring 28; The first sealing ring 27 is disposed between the clamping block 24 and the first channel 20 to block gas leakage along the circumference of the clamping block 24; the second sealing ring 28 is disposed between the valve body 18 and the housing 1 to prevent gas from leaking out from the connection between the valve body 18 and the housing 1.

[0045] It should be noted that in this application, there are gaps between the side wall of the clamping block 24 and the valve body 18, and between the top of the valve body 18 and the valve cap 19.

[0046] By adopting the above technical solution, this application has the following beneficial effects: (1) The technical solution of this application effectively solves the problem that the traditional ventilation structure 4 is difficult to balance sealing and ventilation efficiency under complex working conditions. By sensing the pressure change in the oil cavity in real time, the gas flow path is dynamically adjusted to achieve precise switching between exhaust and intake, and maintain internal pressure balance.

[0047] (2) The technical solution of this application significantly improves the system’s adaptability to frequent temperature changes, avoids the problems of easy blockage and water ingress of traditional respirators, and ensures the stable operation of the transmission system under complex working conditions.

[0048] (3) In this application, the vent valve 5 adopts a one-way valve structure, which only allows the gas in the oil chamber to be discharged outward, preventing external pollutants from entering in the reverse direction. It can also block water from entering the cavity channel when the vehicle is wading through water, and the residual water can be discharged naturally after leaving the water area. The intake valve 6 adopts a normally open valve structure, and its selective breathable membrane only allows air molecules to pass through, blocking liquid water and impurities, effectively preventing water from entering, and ensuring the cleanliness of the oil chamber.

[0049] (4) The technical solution of this application monitors the pressure change in the oil chamber in real time through the pressure sensor 17, and the control processor 16 automatically or manually judges the working condition according to the pressure signal, and automatically or manually controls the on and off state of the electromagnetic controller 14, thereby controlling the displacement of the control rod 9 to achieve precise switching between intake and exhaust working conditions. No manual intervention is required, and the response is rapid and the reliability is high.

[0050] (5) The technical solution of this application effectively avoids problems such as sealing failure caused by pressure accumulation or negative pressure, reduces damage to internal components, and thus extends the service life of the transmission system.

[0051] Example 2 like Figure 1-2 As shown in the figure, this embodiment provides an intelligent control method for the ventilation structure of an intelligent transmission system, including the following steps: S1: The pressure sensor collects the pressure data in the oil chamber of the transmission system in real time and transmits the signal to the control processor to execute step S2; S2: The control processor analyzes and judges the received pressure signal. When the pressure in the oil chamber is higher than the set upper limit, it is determined to be the exhaust condition and step S3 is executed; when the pressure in the oil chamber is lower than the set lower limit, it is determined to be the intake condition and step S4 is executed. S3: When the electromagnetic coil is de-energized, the control lever abuts against the closed end under the action of the spring, so that the vent valve is connected to the connecting port, the high pressure gas in the oil chamber is discharged, and automatic pressure relief is achieved, and step S1 is executed; S4: When the electromagnetic coil is energized, it generates magnetism, which drives the control rod to move axially against the spring force, thereby connecting the intake valve with the communication port, allowing external air to enter the oil chamber through the selective permeable membrane, achieving pressure compensation, and executing step S1.

[0052] This embodiment achieves dynamic balance of oil chamber pressure through closed-loop control logic, effectively avoiding overstress damage to the seals caused by temperature differences or altitude fluctuations.

[0053] Furthermore, the control processor can incorporate an adaptive algorithm to adjust start / stop thresholds based on historical pressure data, improving response accuracy and energy efficiency. The system features self-diagnostic capabilities; when sensor signals are abnormal or the solenoid coil fails, it automatically switches to passive ventilation mode to ensure basic ventilation safety. Its compact structure and high integration make it suitable for applications with stringent sealing requirements, such as new energy vehicle axles and heavy-duty transmissions, significantly reducing maintenance costs and leakage risks. This intelligent control method also supports remote monitoring and data feedback, uploading pressure change trends, valve operation frequency, and fault codes to the on-board diagnostic system in real time via the CAN bus, facilitating predictive maintenance.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
