[0002] The air suspension system of the vehicle needs to be inflated by an air suspension compressor to achieve the adjustment function of the suspension. In order to respond to the needs of the suspension system, the air suspension compressor needs to be started frequently. In order to improve the NVH (Noise, Vibration, Harshness) performance of the suspension system and the requirements of sound absorption and sound insulation, and to enhance the driving experience, an acoustic bag is often used to wrap the periphery of the air suspension compressor, which will form a relatively closed space. The air exchange between this space and the outside world is very small, and the materials used in the acoustic bag structure often do not have good thermal conductivity and heat dissipation performance.

DETAILED DESCRIPTION

[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0032] In the present disclosure, unless otherwise stated, the directional words such as "up", "down", "left", "right", etc. used to indicate directions or positional relationships are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation. Therefore, it cannot be understood as a limitation on the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.

[0033] In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0034] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0035] refer to Figures 1 to 6 As shown, the first aspect of the present disclosure provides a vehicle air suspension system, including an acoustic package 10, an air suspension compressor 20 and an air delivery device 30, wherein the air suspension compressor 20 is arranged in the acoustic package 10, an air inlet end of the air delivery device 30 is connected to the outside atmosphere and / or the vehicle air conditioning duct 40, and an air outlet end of the air delivery device 30 is connected to the interior of the acoustic package 10, so that the air entering the acoustic package 10 from the outside atmosphere and / or the vehicle air conditioning duct 40 can cool the air suspension compressor 20.

[0036] Through the above technical solution, during the operation of the air suspension compressor 20, the air supply device 30 connected to the outside atmosphere and / or the vehicle air-conditioning duct 40 can transport air into the acoustic bag 10, and transport the air in the outside atmosphere and / or the air in the vehicle air-conditioning duct 40 into the acoustic bag 10. After entering the acoustic bag 10 and exchanging heat with the air suspension compressor 20, the air is discharged from the acoustic bag 10, thereby bringing the heat generated by the air suspension compressor 20 out of the acoustic bag 10, thereby achieving the purpose of cooling the air suspension compressor 20, so that the air suspension compressor 20 can be maintained within a more suitable temperature range, thereby improving the compression performance and service life of the air suspension compressor 20.

[0037] Optionally, in an exemplary embodiment provided by the present disclosure, an acoustic cavity 11 may be formed inside the acoustic package 10, and an air inlet and an air outlet respectively connected to the acoustic cavity 11 are formed on the side wall of the acoustic package 10, and the air outlet end of the air delivery device 30 is connected to the acoustic cavity 11 through the air inlet. In this way, air can enter the acoustic cavity 11 from the air inlet formed on the side wall of the acoustic package 10 through the air outlet end of the air delivery device 30, and after exchanging heat with the air suspension compressor 20, it is discharged from the acoustic cavity 11 from the air outlet, and the heat of the air suspension compressor 20 is taken out of the acoustic cavity 11, so as to achieve cooling and heat dissipation of the air suspension compressor 20.

[0038] Furthermore, the vehicle air suspension system may further include a power transmission component 60, which is used to transmit the power generated by the air suspension compressor 20 during operation to the air delivery device 30 to drive the air delivery device 30 to operate. In this way, under the action of the power transmission component 60, the air delivery device 30 can be driven to provide a driving force for the air in the outside atmosphere and / or the cold air in the vehicle air conditioning duct 40 to enter the acoustic cavity 11, thereby cooling the air suspension compressor 20 located in the acoustic cavity 11.

[0039] The present disclosure does not limit the specific structure and transmission mode of the power transmission component 60. For example, in an exemplary embodiment provided by the present disclosure, the power transmission component 60 can be connected to the rotating shaft of the air suspension compressor 20. In this way, when the air suspension compressor 20 compresses air, the power transmission component 60 can be driven to move, thereby driving the air delivery device 30. In the above process, there is no need to provide additional driving force for the air delivery device 30 to drive the air flow, which can simplify the overall structure of the air delivery device 30 and effectively reduce the energy consumption in the air driving process.

[0040] Alternatively, in another embodiment provided by the present disclosure, the air delivery device 30 may be a first rotary power structure 31, and the power transmission assembly 60 may include a second rotary power structure 61 and a transmission structure 62, wherein the second rotary power structure 61 is in communication with the air suspension compressor 20, so that the second rotary power structure 61 can rotate under the action of the airflow generated when the air suspension compressor 20 is in operation, and the second rotary power structure 61 is connected to the first rotary power structure 31 through the transmission structure 62. In other words, the airflow generated when the air suspension compressor 20 is in operation can drive the second rotary power structure 61 to rotate, and since the second rotary power structure 61 is connected to the first rotary power structure 31 through the transmission structure 62, the second rotary power structure 61 can drive the first rotary power structure 31 to rotate when rotating, and the first rotary power structure 31 can generate suction force on the air in the outside atmosphere and / or the air in the vehicle air conditioning duct 40 when rotating, thereby driving the above-mentioned air to flow in and out of the acoustic cavity 11, and realizing cooling of the air suspension compressor 20 located in the acoustic cavity 11.

[0041] Furthermore, in the above process, the energy of the air sucked in during the operation of the air suspension compressor 20 can be recovered and utilized without the need to separately provide a driving structure or driving device for driving the first rotary power structure 31 to rotate, thereby streamlining the overall structure of the vehicle air suspension system and reducing the energy consumption and cooling cost during the cooling process of the air suspension compressor 20.

[0042] Alternatively, in other embodiments provided in the present disclosure, the driving of the first rotary power structure 31 may be achieved by providing a driving structure (such as a rotary motor).

[0043] Alternatively, if Figure 5 , Figure 6 As shown, the first rotary power structure 31 may include a first blade 311, the second rotary power structure 61 may include a second blade 611, the transmission structure 62 may include a transmission shaft 620, and the first blade 311 and the second blade 611 are coaxially arranged and connected through the transmission shaft 620. In this way, when the second blade 611 senses the airflow generated when the air suspension compressor 20 is running and rotates, since the first blade 311 is coaxially arranged with the second blade 611, the first blade 311 can rotate synchronously with the second blade 611, that is, the first blade 311 has a faster response speed, and once the air suspension compressor 20 starts to run, the first blade 311 starts to rotate immediately, thereby realizing rapid cooling of the air suspension compressor 20.

[0044] Furthermore, because the first blade 311 and the second blade 611 are coaxially arranged and connected through the transmission shaft 620, the related structures for connection and transmission between the first blade 311 and the second blade 611 can be simplified, making it easier to install and arrange the first blade 311 and the second blade 611.

[0045] In an exemplary embodiment provided by the present disclosure, the first rotary power structure 31 may be a first turbine 310, and the second rotary power structure 61 may be a second turbine 610. The turbine has a higher transmission efficiency, and thus can improve the conversion rate of the energy of the airflow generated when the air suspension compressor 20 is in operation, thereby improving the flow rate and flow rate of the air entering the acoustic cavity 11.

[0046] Specifically, Figure 5 , Figure 6As shown, for the embodiment in which the first rotary power structure can be the first turbine 310 and the second rotary power structure 61 can be the second turbine 610, the first turbine 310 can include a first shell 312, a first air inlet 313 formed on the first shell 312, a first air outlet 314 and the first blades 311. Similarly, the second turbine 610 can include a second shell 612, a second air inlet 613 formed on the second shell 612, a second air outlet 614 and the second blades 611. Similarly, when the air suspension compressor 20 is running, air can enter the second shell 612 from the second air inlet 613, thereby driving the second blade 611 to rotate, and allowing the air to flow out of the shell from the second air outlet 614 to enter or flow out of the air suspension compressor 20. At the same time, the rotation of the second blade 611 drives the first blade 311 to rotate synchronously, so that the outside atmosphere or the air in the vehicle air-conditioning duct 40 can be sucked into the first shell 312 through the first air inlet 313, and the air is delivered to the acoustic cavity 11 through the first air outlet 314.

[0047] In addition, in order to cope with different usage scenarios, the present disclosure can achieve the above-mentioned first blade 311 and the second blade 611 rotating in the same direction or in the opposite direction by adjusting the direction in which air enters the first shell 312 and the second shell 612, such as Figure 5 As shown, the air intake directions of the first turbine 310 and the second turbine 610 are opposite, while the air outlet directions of the first turbine 310 and the second turbine 610 are the same. Figure 6 In the embodiment, the air intake direction of the first turbine 310 and the second turbine 610 is the same, while the air outlet directions of the first turbine 310 and the second turbine 610 are opposite. In this way, the positional relationship between the first turbine 310 and the acoustic package 10, and the positional relationship between the second turbine 610 and the vehicle air-conditioning duct 40 and the air suspension compressor 20 can be adjusted by adjusting the direction in which air enters the first turbine 310 and the second turbine 610. For example, the first turbine 310 can be connected to the upstream of the acoustic package 10 or to the downstream of the acoustic package 10. Similarly, the second turbine 610 can be arranged upstream of the air suspension compressor 20 or to the downstream of the air suspension compressor 20. This allows the present invention to have more diverse assembly methods and is more convenient for flexible arrangement of the above-mentioned structures.

[0048] Alternatively, in other embodiments provided in the present disclosure, the first rotary power structure 31 and the second rotary power structure 61 may also be structures such as exhaust fans and air pumps. The present disclosure does not impose any restrictions on this. In short, as long as the air in the outside atmosphere and / or the air in the vehicle air-conditioning duct 40 can be sucked, it will be fine.

[0049] The present disclosure does not limit the specific positional relationship between the second rotary power structure 61 and the air suspension compressor 20. For example, in an exemplary embodiment provided in the present disclosure, Figure 1 , Figure 2 As shown, the second rotary power structure 61 can be located upstream of the air suspension compressor 20. Specifically, the air inlet of the second rotary power structure 61 is used to communicate with the outside atmosphere, and the air outlet of the second rotary power structure 61 is communicated with the air inlet of the air suspension compressor 20. In this way, during the operation of the air suspension compressor 20, the air inlet of the air suspension compressor 20 draws air from the outside atmosphere, and the air enters the inside of the second rotary power structure 61 during the flow, and enters the inside of the air suspension compressor 20 from the air outlet of the second rotary power structure 61. In the process of the air entering the inside of the second rotary power structure 61, the second blade 611 of the second rotary power structure 61 and the transmission shaft 620 connected to the second blade 611 can be driven to rotate, thereby driving the first blade 311 connected to the transmission shaft 620 to rotate. When the first blade 311 rotates, the air in the outside atmosphere and / or the air in the vehicle air conditioning duct 40 can be continuously driven into the acoustic cavity 11, so as to achieve continuous cooling and heat dissipation of the air suspension compressor 20.

[0050] On the other hand, Figure 1 , Figure 2 As shown, the vehicle air suspension system further includes an air spring module 70 and an air suspension accumulator 80, and the air outlet of the air suspension compressor 20 can be communicated with the air spring module 70 and / or the air suspension accumulator 80 of the vehicle. In this way, in the above-mentioned process of cooling and dissipating the heat of the air suspension compressor 20, the normal operation of the air spring module 70 and / or the air suspension accumulator 80 will not be affected, and the air compressed by the air suspension compressor 20 can be provided to the air spring module 70 and / or the air suspension accumulator 80 via the air outlet.

[0051] Alternatively, in another embodiment provided by the present disclosure, Figure 3 , Figure 4As shown, the vehicle air suspension system also includes an air spring module 70 and an air suspension accumulator 80. The second rotary power structure 61 can be located downstream of the air suspension compressor 20. Specifically, the air inlet of the second rotary power structure 61 is connected to the air outlet of the air suspension compressor 20, and the air outlet of the second rotary power structure 61 is connected to the air spring module 70 and / or the air suspension accumulator 80. In this embodiment, the air inlet of the second rotary power structure 61 is connected to the air outlet of the air suspension compressor 20, and the air outlet of the second rotary power structure 61 is connected to the air spring module 70 and / or the air suspension accumulator 80, that is, the second rotary power structure 61 is arranged between the air suspension compressor 20 and the air spring module 70 and / or the air suspension accumulator 80, so that when the air suspension compressor 20 provides compressed air with a certain flow velocity to the air spring module 70 and / or the air suspension accumulator 80, when the compressed air flows through the second rotary power structure 61, the second blade 611 can be driven, and then the first blade 311 can be driven, so as to achieve the purpose of driving the air into the acoustic cavity 11 to cool the air suspension compressor 20.

[0052] In one embodiment provided by the present disclosure, optionally, as Figure 3 , Figure 4 As shown, the air inlet of the air suspension compressor 20 is connected to the outside atmosphere or the air suspension accumulator 80 of the vehicle. That is, when the air suspension compressor 20 extracts air from the outside atmosphere and / or the air suspension accumulator 80, the air can drive the second blade 611 and the first blade 311 to rotate when flowing through the second rotary power structure 61, thereby extracting air in the outside atmosphere and / or air in the vehicle air conditioning duct 40 into the acoustic cavity 11.

[0053] like Figures 1 to 4As shown, when the air suspension descends, the high-pressure air in the air spring module 70 is discharged to the second rotary power structure 61 through the air suspension compressor 20, driving the second blade 611 of the second rotary power structure 61 to reverse and then be discharged into the atmosphere. However, when the second blade 611 reverses, the first blade 311 also reverses. At this time, there will be a problem that the first blade 311 sucks the air in the acoustic cavity 11 into the vehicle air conditioning duct 40, causing pollution to the air in the passenger compartment 50. Based on this, in one embodiment provided by the present disclosure, the air inlet end of the air delivery device 30 is connected to the vehicle air conditioning duct 40 via the first one-way valve 90. It should be noted that the above-mentioned first one-way valve 90 can allow air to flow from the vehicle air-conditioning duct 40 into the air inlet end of the air supply device 30, while blocking air from entering the vehicle air-conditioning duct 40 from the air inlet end of the air supply device 30. In this way, the air supply device 30 can extract cold air from the vehicle air-conditioning duct 40, and can also avoid the problem of the first blade 311 reversing and sucking the air in the acoustic cavity 11 into the vehicle air-conditioning duct 40 and even the passenger compartment 50, thereby polluting the air in the passenger compartment 50.

[0054] In addition, if Figure 1 , Figure 2 As shown, the above-mentioned vehicle air suspension system may further include an air filter 130. Thus, in the process of the air suspension compressor 20 sucking in external atmospheric air, the air filter 130 may filter the air in the atmosphere to ensure the cleanliness of the air entering the air suspension compressor 20, the air spring module 70 and / or the air suspension accumulator 80.

[0055] In an exemplary embodiment provided by the present disclosure, Figures 1 to 4 As shown, the vehicle air suspension system may further include a three-way valve 100, wherein a first interface of the three-way valve 100 is connected to the air inlet end of the air delivery device 30, a second interface of the three-way valve 100 is connected to the first one-way valve 90, and a third interface of the three-way valve 100 is connected to the outside atmosphere. In this way, through the setting of the three-way valve 100, in the process of the air delivery device 30 driving the air to enter the acoustic cavity 11, the air may come from both the outside atmosphere and the vehicle air conditioning duct 40, or the above-mentioned cooling air may also be partially from the outside atmosphere and the other part from the vehicle air conditioning duct 40, and the user may realize this by controlling the switch and opening of the three-way valve 100.

[0056] Specifically, when the outside atmospheric temperature is high or the outside atmospheric temperature is not much different from the temperature in the acoustic cavity 11, the first interface of the three-way valve 100 can be controlled to be opened, the second interface can be controlled to be opened, and the third interface of the three-way valve 100 can be closed. In this way, the air supply device 30 can flow the air with a lower temperature in the vehicle air-conditioning duct 40 into the acoustic cavity 11 through the second interface and the first interface of the three-way valve 100. At this time, the air with a lower temperature has a large temperature difference with the air in the acoustic cavity 11, so it can have a better cooling effect on the air suspension compressor 20; when the outside atmospheric temperature is low (such as winter) or the outside atmospheric temperature is greatly different from the temperature in the acoustic cavity 11, the first interface and the third interface of the three-way valve 100 can be controlled to be opened, and the second interface can be closed. At this time, the air supply structure can extract air from the outside atmosphere to cool the air suspension compressor 20 in the acoustic cavity 11, which can also achieve a better cooling effect.

[0057] For the implementation in which the third interface of the three-way valve 100 is connected to the outside atmosphere, the first one-way valve 90 may be disposed in the third interface of the three-way valve 100 .

[0058] Here, in order to monitor the temperature in the acoustic cavity 11 , a temperature sensor may be disposed in the acoustic cavity 11 .

[0059] In order to ensure the comfort of the passengers, the vehicle air conditioner can keep the ambient temperature in the passenger compartment 50 at a relatively low and comfortable temperature, which is much lower than the temperature of the air inside the acoustic cavity 11 during the operation of the air suspension compressor 20. Based on this, in an exemplary embodiment provided by the present disclosure, the air inlet end of the air delivery device 30 is used to communicate with the vehicle air conditioning duct 40 through the passenger compartment 50 of the vehicle. Therefore, when the low-temperature air in the passenger compartment 50 is drawn into the acoustic package 10, the low-temperature air has a large temperature difference with the air in the acoustic cavity 11, and can more quickly achieve heat exchange with the high-temperature air in the acoustic cavity 11.

[0060] Alternatively, if Figures 1 to 4 As shown, the vehicle air suspension system further includes a connecting pipe 110 and a second one-way valve 120, one end of the connecting pipe 110 is connected to the outside atmosphere, the other end of the connecting pipe 110 is connected to the air inlet end of the air delivery device 30, and the second one-way valve 120 is arranged in the connecting pipe 110. The second one-way valve 120 is arranged to allow air to flow from the acoustic cavity 11 to the outside atmosphere, but not to allow air in the outside atmosphere to enter the acoustic cavity 11, so that when the second blade 611 reverses and drives the first blade 311 to reverse, the air sucked back by the reverse rotation of the first blade 311 can be discharged from the connecting pipe 110 to the outside atmosphere via the second one-way valve 120, and when the air delivery device 30 needs to extract air in the vehicle air conditioning duct 40, it can prevent the outside air from entering the acoustic cavity 11 through the connecting pipe 110.

[0061] Alternatively, it is also possible to set a switch valve in the third interface of the three-way valve 100 to achieve the operation of air entering the acoustic cavity 11 from the outside atmosphere, air entering the acoustic cavity 11 from the vehicle air-conditioning duct 40, and air being discharged from the acoustic cavity 11 to the outside atmosphere. Specifically, when it is necessary to draw air into the acoustic cavity 11, the switch valve set in the third interface can be opened. At this time, under the suction action of the air supply device 30, the outside atmosphere can be drawn into the acoustic cavity 11 through the third interface of the three-way valve 100; when it is necessary to draw cold air from the vehicle air-conditioning duct 40, the switch valve can be closed. At this time, the outside air cannot enter the acoustic cavity 11 through the third interface, that is, the air in the outside atmosphere will not be accidentally inhaled; when it is necessary to discharge the air in the acoustic cavity 11, the switch valve can be opened. At this time, the air in the acoustic cavity 11 can be discharged to the atmosphere through the third interface of the three-way valve 100.

[0062] The second aspect of the present disclosure provides a vehicle, comprising the above vehicle air suspension system. The vehicle has all the beneficial effects of the above vehicle air suspension system, which will not be elaborated in the present disclosure.
