Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle parts, in particular to a gas supply assembly, an air suspension system and a vehicle. BACKGROUND

[0002] The air suspension of a vehicle is a suspension system that uses air springs as elastic elements. It can adjust the hardness and height of the suspension by compressing air to adapt to different road conditions and driving needs. The air suspension is usually adjusted by a gas supply system in the vehicle. For example, for a closed-loop gas supply system, high-pressure gas in an air storage unit flows to the air spring through an air compressor or directly, and the high-pressure gas in the air spring can also be pressurized by the air compressor and then flow back to the air storage unit. In the related art, in order to realize different flow paths and meet different application scenarios, the closed-loop gas supply system usually needs to be matched with multiple control valves and multiple air paths, resulting in an increase in the cost of the gas supply system and an increase in the difficulty of processing and arrangement.

DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor are within the protection scope of the present application.

[0052] In a first aspect, referring to Figure 1 , the present application provides a gas supply assembly 100. The gas supply assembly 100 provided by the present application comprises a pressurizing unit 1, a gas storage unit 2, a first multi-way valve 3 and a second multi-way valve 4. The first end of the first multi-way valve 3 is in communication with the air inlet end of the pressurizing unit 1, the second end of the first multi-way valve 3 is in communication with the air outlet end of the pressurizing unit 1, and the third end of the first multi-way valve 3 is in communication with the gas receiving unit 5 in the vehicle. The first end of the second multi-way valve 4 is in communication with the gas receiving unit 5, and the second end of the second multi-way valve 4 is in communication with the gas storage unit 2. In addition, the fourth end of the first multi-way valve 3 is in communication with the third end of the second multi-way valve 4.

[0053] By controlling the on-off relationship between the ends of the first multi-way valve 3 and the second multi-way valve 4, different gas supply modes can be realized. For example, when the second end and the third end of the first multi-way valve 3 are communicated, the first end and the fourth end of the first multi-way valve 3 are communicated, and the second end and the third end of the second multi-way valve 4 are communicated, the gas in the gas storage unit 2 can be used to charge the gas receiving unit 5 after being pressurized by the pressurizing unit 1. When the first end and the third end of the first multi-way valve 3 are communicated, the second end and the fourth end of the first multi-way valve 3 are communicated, and the second end and the third end of the second multi-way valve 4 are communicated, the gas discharged from the gas receiving unit 5 can be stored in the gas storage unit 2 after being pressurized by the pressurizing unit 1.

[0054] The gas supply assembly 100 provided by the embodiment of the present application realizes the integration of at least part of the control valves through the first multi-way valve 3 and the second multi-way valve 4, and does not need to separately set control valves and gas paths for all circuits, thereby reducing the number of control valves and gas paths in the gas supply assembly 100. On the one hand, the control logic of the gas supply assembly 100 can be optimized, and the arrangement difficulty of the control valves and the gas paths is reduced, and on the other hand, the number of control valves and gas paths is saved, and the raw material cost is saved.

[0055] That is, the integration of at least part of the control valves in the gas supply assembly 100 is realized by setting the first multi-way valve 3 and the second multi-way valve 4. In actual use, different gas supply modes can be realized by controlling the working state of the first multi-way valve 3 and the second multi-way valve 4, and the control logic is optimized. Moreover, since the first multi-way valve 3 and the second multi-way valve 4 are used to replace the plurality of independent control valves in the related art, the gas paths in the gas supply assembly 100 can also be integrated in the first multi-way valve 3 and the second multi-way valve 4, thereby reducing the number of gas paths and reducing the arrangement difficulty caused by too many gas paths.

[0056] In some embodiments, the first multi-way valve 3 is configured to control the on-off between the third end and the first end and the second end of the first multi-way valve 3, and is also configured to control the on-off between the fourth end and the first end and the second end of the first multi-way valve 3.

[0057] That is, the first multi-way valve 3 can realize the on-off switching between the third end and the fourth end and the first end and the second end, so as to realize the on-off switching between the gas receiving unit 5 and the gas inlet end of the pressurizing unit 1 and the gas outlet end of the pressurizing unit 1, and realize the on-off switching between the second multi-way valve 4 and the gas inlet end of the pressurizing unit 1 and the gas outlet end of the pressurizing unit 1, thereby realizing a plurality of gas supply modes.

[0058] In some embodiments, the second multi-way valve 4 is configured to control the on-off between the second end and the first end and the third end of the second multi-way valve 4.

[0059] That is, the second multi-way valve 4 can realize the switching of the connection between the first end, the second end and the third end, so as to realize the switching of the connection between the fourth end of the first multi-way valve 4, the gas receiving unit 5 and the gas storage unit 2, and further realize multiple gas supply modes.

[0060] In some embodiments, referring to Figures 1-5 , the first multi-way valve 3 includes a two-position four-way valve. When the two-position four-way valve is in a first state, the first end of the first multi-way valve 3 is in communication with the fourth end thereof, and the second end of the first multi-way valve 3 is in communication with the third end thereof, so that the gas inlet end of the pressurizing unit 1 is adapted to be in communication with the gas receiving unit 5, and the gas outlet end of the pressurizing unit 1 is adapted to be in communication with the third end of the second multi-way valve 4. When the two-position four-way valve is in a second state, the first end of the first multi-way valve 3 is in communication with the third end thereof, and the second end of the first multi-way valve 3 is in communication with the fourth end thereof, so that the gas inlet end of the pressurizing unit 1 is adapted to be in communication with the third end of the second multi-way valve 4, and the gas outlet end of the pressurizing unit 1 is adapted to be in communication with the gas receiving unit 5.

[0061] The two-position four-way valve includes two gas inlet ports and two gas outlet ports, and by adjusting the working state of the two-position four-way valve, the communication relationship between the gas inlet ports and the gas outlet ports can be switched, and different communication states can be realized.

[0062] When the two-position four-way valve is in the first state, the gas inlet end of the pressurizing unit 1 is adapted to be in communication with the gas receiving unit 5, and the gas outlet end of the pressurizing unit 1 is adapted to be in communication with the third end of the second multi-way valve 4. The second end of the second multi-way valve 4 is in communication with the gas storage unit 2, and when the second end and the third end of the second multi-way valve 4 are in communication, the gas discharged from the gas receiving unit 5 enters the pressurizing unit 1 through the gas inlet end of the pressurizing unit 1, is pressurized by the pressurizing unit 1, and then enters the gas storage unit 2 through the gas outlet end of the pressurizing unit 1, the third end of the second multi-way valve 4 and the second end of the second multi-way valve 4.

[0063] When the two-position four-way valve is in the second state, the gas inlet end of the pressurizing unit 1 is adapted to be in communication with the third end of the second multi-way valve 4, and the gas outlet end of the pressurizing unit 1 is adapted to be in communication with the gas receiving unit 5. The second end of the second multi-way valve 4 is in communication with the gas storage unit 2, and when the second end and the third end of the second multi-way valve 4 are in communication, the gas stored in the gas storage unit 2 enters the pressurizing unit 1 through the second end of the second multi-way valve 4 and the third end of the second multi-way valve 4, is pressurized, and then enters the gas receiving unit 5 to charge the gas receiving unit 5.

[0064] That is, by switching the state of the two-position four-way valve, different communication states between the pressurizing unit 1, the gas storage unit 2 and the gas receiving unit 5 are realized, different modes are realized, and multiple separate control valves and gas paths in the related art are replaced, realizing integration and optimizing the control logic.

[0065] In some embodiments, referring toFigure 1 The air supply assembly 100 further comprises an air filter unit 6. One end of the air filter unit 6 is adapted to communicate with the fourth end of the first multi-way valve 3, and the other end of the air filter unit 6 is adapted to communicate with the outside.

[0066] By controlling the working state of the first multi-way valve 3, the air filter unit 6 can be made to communicate with the air inlet end of the pressurizing unit 1. Since the other end of the air filter unit 6 communicates with the outside, the pressurizing unit 1 can directly absorb air from the outside, and after being pressurized, provide the air receiving unit 5 with more air supply modes.

[0067] The air filter unit 6 can filter the air from the outside, reducing the risk of impurities entering the pressurizing unit 1.

[0068] In some embodiments, referring to Figure 1 A one-way valve 61 is provided on the communication pipeline between the air filter unit 6 and the fourth end of the first multi-way valve 3, and the one-way valve 61 is used to make the gas flow from the air filter unit 6 to the first multi-way valve 3.

[0069] By providing the one-way valve 61, the flow direction of the gas can be controlled, so that the pressurizing unit 1 can absorb air from the outside, and after being pressurized, provide the air receiving unit 5, but the gas in the air receiving unit 5 and the gas storage unit 2 cannot be discharged to the outside through the air filter unit 6, reducing the risk of gas loss in the air supply assembly 100.

[0070] In some embodiments, referring to Figure 2 The second multi-way valve 4 comprises a three-position three-way valve. When the three-position three-way valve is in a first state, the first end, the second end and the third end of the second multi-way valve 4 are all blocked from each other, so that the fourth end of the first multi-way valve 3, the air receiving unit 5 and the gas storage unit 2 are all blocked from each other. When the three-position three-way valve is in a second state, the first end and the third end of the second multi-way valve 4 are communicated, so that the gas storage unit 2 communicates with the air receiving unit 5, the fourth end of the first multi-way valve 3 remains blocked from the air receiving unit 5, and the fourth end of the first multi-way valve 3 is blocked from the gas storage unit 2. When the three-position three-way valve is in a third state, the second end and the third end of the second multi-way valve 4 are communicated, so that the fourth end of the first multi-way valve 3 communicates with the gas storage unit 2, the air receiving unit 5 is blocked from the fourth end of the first multi-way valve 3, and the air receiving unit 5 is blocked from the gas storage unit 2.

[0071] When the three-position three-way valve is in the first state, the communication between the gas storage unit 2 and the gas receiving unit 5 and the pressurizing unit 1 is blocked, and the pressurizing unit 1 can directly absorb ambient air to pressurize the gas in the gas receiving unit 5. When the three-position three-way valve is in the second state, the gas storage unit 2 can directly supply gas to the gas receiving unit 5, or the gas in the gas receiving unit 5 is directly stored in the gas storage unit 2. When the three-position three-way valve is in the third state, the gas in the gas receiving unit 5 can be pressurized by the pressurizing unit 1 and then stored in the gas storage unit 2, or the gas stored in the gas storage unit 2 can be pressurized by the pressurizing unit 1 and then supplied to the gas receiving unit 5.

[0072] In some embodiments, referring to Figure 3 , the second multi-way valve 4 comprises a rotary three-way valve. When the rotary three-way valve is in the first state, the first end, the second end and the third end of the second multi-way valve 4 are all blocked from each other, so that the fourth end of the first multi-way valve 3, the gas receiving unit 5 and the gas storage unit 2 are all blocked from each other. When the rotary three-way valve is in the second state, the first end and the third end of the second multi-way valve 4 are communicated, so that the gas storage unit 2 is communicated with the gas receiving unit 5, the fourth end of the first multi-way valve 3 is kept blocked from the gas receiving unit 5, and the fourth end of the first multi-way valve 3 is blocked from the gas storage unit 2. When the rotary three-way valve is in the third state, the second end and the third end of the second multi-way valve 4 are communicated, so that the fourth end of the first multi-way valve 3 is communicated with the gas storage unit 2, the gas receiving unit 5 is blocked from the fourth end of the first multi-way valve 3, and the gas receiving unit 5 is blocked from the gas storage unit 2.

[0073] The rotary three-way valve can realize similar states of the three-position three-way valve, with the difference being the way of state switching, which will not be repeated again.

[0074] In some embodiments, referring to Figure 4 , the second multi-way valve 4 comprises a two-position three-way valve. When the two-position three-way valve is in the first state, the first end and the third end of the second multi-way valve 4 are communicated, so that the gas storage unit 2 is communicated with the gas receiving unit 5, the fourth end of the first multi-way valve 3 is kept blocked from the gas receiving unit 5, and the fourth end of the first multi-way valve 3 is blocked from the gas storage unit 2. When the two-position three-way valve is in the second state, the second end and the third end of the second multi-way valve 4 are communicated, so that the fourth end of the first multi-way valve 3 is communicated with the gas storage unit 2, the gas receiving unit 5 is blocked from the fourth end of the first multi-way valve 3, and the gas receiving unit 5 is blocked from the gas storage unit 2.

[0075] Compared with the three-position three-way valve, the two-position three-way valve cannot block the fourth end of the first multi-way valve 3, the gas receiving unit 5 and the gas storage unit 2 from each other. That is, when the two-position three-way valve is used, the pressurizing unit 1 cannot directly absorb ambient air to pressurize the gas in the gas receiving unit 5, but other states remain the same as the three-position three-way valve, which will not be repeated again.

[0076] In some embodiments, referring to Figure 1 , the gas supply assembly 100 further comprises a drying unit 7. The drying unit 7 is arranged on the communication pipeline between the gas outlet end of the pressurizing unit 1 and the first end of the first multi-way valve 3.

[0077] The gas output by the pressurizing unit 1 first passes through the drying unit 7, and then enters the gas receiving unit 5 or the gas storage unit 2 through the first multi-way valve 3, so that the gas entering the gas receiving unit 5 or the gas storage unit 2 can be dried.

[0078] In some embodiments, referring to Figure 1 , the gas supply assembly 100 further comprises a pressure relief valve 8. The first end of the pressure relief valve 8 is in communication with the gas outlet end of the pressurizing unit 1 and / or the end of the drying unit 7 away from the first multi-way valve 3, and the second end of the pressure relief valve 8 is in communication with the outside.

[0079] Through the pressure relief valve 8, the drying agent in the drying unit 7 can be regenerated. That is, when the pressure relief valve 8 is opened, the dry gas in the gas receiving unit 5 or the gas storage unit 2 can pass through the drying unit 7, take away the moisture in the drying unit 7, promote the regeneration of the drying agent, and then be discharged to the outside through the pressure relief valve 8.

[0080] In addition, by arranging the pressure relief valve 8, when the pressure of the pressurizing unit 1 is too high, it can also be released to the outside through the pressure relief valve 8, reducing the risk.

[0081] Exemplarily, the pressure relief valve 8 is a two-position two-way valve.

[0082] In some embodiments, the pressurizing unit 1 comprises an air compressor. The air compressor can pressurize the air in a short time to reach the required pressure range, thereby supplying the gas. The air compressor also has good reliability and adaptability, which can meet the needs of the gas supply assembly 100.

[0083] In some embodiments, the gas storage unit 2 comprises a gas storage tank. The gas storage tank can store the gas pressurized by the pressurizing unit 1, or store the high-pressure gas discharged by the gas receiving unit 5, and also can provide the stored high-pressure gas to the gas receiving unit 5. By adopting the gas storage tank as the gas storage unit 2, more gas supply modes can be provided, and the stability and reliability of the gas supply assembly 100 can be enhanced.

[0084] In some embodiments, referring to Figure 5 , the gas supply assembly 100 further comprises at least one intake control valve 9. The third end of the first multi-way valve 3 is in communication with the gas receiving unit 5 through the intake control valve 9, and / or the first end of the second multi-way valve 4 is in communication with the gas receiving unit 5 through the intake control valve 9.

[0085] By setting the at least one intake control valve 9, the communication relationship between the pressurizing unit 1 and / or the gas storage unit 2 and the gas receiving unit 5 can be further controlled.

[0086] According to a second aspect of the present application, there is also provided an air suspension system comprising the air supply assembly 100 as above.

[0087] The air suspension system provided by the present application has all the beneficial effects of the air supply assembly 100 as above, which will not be repeated here.

[0088] In some embodiments, referring to Figure 5 , the air suspension system further comprises an air suspension assembly 51. The air suspension assembly 51 communicates with the air supply assembly 100 as the gas receiving unit 5.

[0089] That is, in the air suspension system, the air suspension assembly 51, as the gas receiving unit 5 described above, cooperates with the pressurizing unit 1, the gas storage unit 2, the first multi-way valve 3 and the second multi-way valve 4 in the air supply assembly 100 to realize multiple air supply modes, and the integration of at least part of the control valves is realized through the first multi-way valve 3 and the second multi-way valve 4, which can optimize the control logic of the air supply assembly 100, reduce the difficulty of arranging the control valves and the air path, and save the number of control valves and air paths, thereby saving the cost of raw materials.

[0090] In some embodiments, referring to Figure 5 , the air suspension assembly 51 comprises a plurality of air springs, and each air spring is provided with a corresponding intake control valve 9.
