[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] like Figures 1 to 6As shown, according to the first aspect of the present application, a compressor is provided, including: a pump body assembly 10, having a first air inlet 11 and a first air outlet 12; an air circuit block assembly 20, having a pipeline control structure, and a first interface 21, a second interface 22, a shock absorber interface and an air tank interface 35 connected to the pipeline control structure, the first interface 21, the second interface 22, the shock absorber interface and the air tank interface 35 are respectively arranged on the pipeline control structure, the first interface 21 is connected to the first air inlet 11, and the first air outlet 12 is connected to the second interface 22; the pipeline control structure is used to control the connection and disconnection between the second interface 22 and the shock absorber interface and the air tank interface 35, and the pipeline control structure is also used to control the connection and disconnection between the first interface 21 and the air tank interface 35.

[0042] In this way, the pipeline control structure controls the connection between the second interface 22 and the shock absorber interface and the air tank interface 35 respectively, so as to replenish air to at least one of the shock absorber and the air tank 50 through the pump body assembly 10 to realize the open mode. By controlling the connection between the first interface 21 and the air tank interface 35, the gas in the air tank 50 returns to the pump body assembly 10 through the first interface 21 for re-compression, thereby realizing the open boost mode. By controlling the connection between the first interface 21 and the shock absorber interface, the gas in the shock absorber returns to the pump body assembly 10 through the first interface 21 for re-compression, thereby realizing the closed mode. In this way, the compressor mode is diversified and the switching is simple, so that the development cost of the compressor is low to meet the user's usage needs.

[0043] Optionally, the pipeline control structure has an open mode, an open boost mode and a closed mode. When the pipeline control structure is in the open mode, the second interface 22 can be controlled to be connected to the shock absorber interface and the gas tank interface 35 respectively, and the shock absorber interface and the gas tank interface 35 can be controlled to be connected, and the second interface 22 is disconnected from the gas tank interface 35 and the shock absorber interface; when the pipeline control structure is in the open boost mode, the first interface 21 can be controlled to be connected to the gas tank interface 35, and the second interface 22 is controlled to be connected to the shock absorber interface; when the pipeline control structure is in the closed mode, the shock absorber interface can be controlled to be connected to the first interface 21, and the second interface 22 is controlled to be connected to the gas tank interface 35. Switching between the three modes can be realized in this way, which can meet the requirements of improving the applicability and scope of application of the device.

[0044] Optionally, the pipeline control structure includes an external interface connected to the second interface 22, and a control valve 25 is provided between the external interface and the shock absorber interface to control the on-off between the second interface 22 and the shock absorber interface. In this way, the air pressure in the shock absorber can be adjusted in time to meet the vibration reduction requirements of the device.

[0045] Optionally, a control valve 25 is provided between the external interface and the gas tank interface 35 to control the on-off between the second interface 22 and the gas tank interface 35. With this arrangement, the gas tank 50 can be inflated or discharged at any time to meet the use requirements of the device.

[0046] Optionally, there are multiple shock absorber interfaces, and a control valve 25 is provided between each shock absorber interface and the external interface to control the connection and disconnection between the second interface 22 and each shock absorber interface. This arrangement can ensure that each shock absorber is independently controlled, and the operation of the shock absorbers will not interfere with each other, which is conducive to maintaining the stability of the shock absorber during operation.

[0047] Optionally, the shock absorber interface includes a third interface 31, a fourth interface 32, a fifth interface 33 and a sixth interface 34, and the shock absorber includes a first shock absorber 61, a second shock absorber 62, a third shock absorber 63 and a fourth shock absorber 64, the third interface 31 is connected to the first shock absorber 61, the fourth interface 32 is connected to the second shock absorber 62, the fifth interface 33 is connected to the third shock absorber 63, and the sixth interface 34 is connected to the fourth shock absorber 64. In the present application, the first shock absorber 61 corresponds to the front right shock absorber of the vehicle, the second shock absorber 62 corresponds to the front left shock absorber of the vehicle, the third shock absorber 63 corresponds to the rear left shock absorber of the vehicle, and the fourth shock absorber 64 corresponds to the rear right shock absorber of the vehicle. In this way, all-round vibration reduction adjustment of the vehicle can be achieved, thereby improving the driving stability of the vehicle.

[0048] Optionally, a control valve 25 is provided between the third interface 31 and the first shock absorber 61, between the fourth interface 32 and the second shock absorber 62, between the fifth interface 33 and the third shock absorber 63, and between the sixth interface 34 and the fourth shock absorber 64. The control valve 25 is used to realize individual control of multiple shock absorbers to meet the vibration reduction requirements of the vehicle as much as possible.

[0049] Optionally, the gas circuit block assembly 20 further includes a dryer 40, the interface of which is respectively connected to the second interface 22 and the external interface to dry the gas in the air intake pipeline or the gas in the pipeline of the gas circuit block assembly 20. By setting the above structure, moisture and particulate matter in the compressed air can be removed, effectively preventing moisture from corroding the pneumatic actuators and pipelines, extending the service life of the equipment, and ensuring the safety and long-term reliable operation of the gas circuit block assembly 20.

[0050] Optionally, a control valve 25 is provided between the first interface 21 and the shock absorber interface, so that the gas flow direction between the first interface 21 and the shock absorber interface can be adjusted in time to meet the use requirements of the device.

[0051] Optionally, the control valve 25 includes a normally closed solenoid valve. When the power supply of the normally closed solenoid valve is cut off, the magnetic core will lose its magnetism and the valve will automatically close. This design ensures that the valve is closed in the event of a power outage or abnormality, effectively preventing gas leakage, thereby ensuring the stability of the device during operation. Of course, in other embodiments of the present application, the solenoid valve can also be set to other types.

[0052] Optionally, the shock absorber includes an air spring. An air spring is a spring filled with compressed air in a retractable closed container, which uses the elasticity of air, commonly known as an air bag, an air bag cylinder, a leather bag cylinder, etc.

[0053] The working principle of air springs is based on the change of air pressure and volume. Inert gas or oil-gas mixture is filled into a closed pressure cylinder, so that the pressure in the cavity is several or dozens of times higher than the atmospheric pressure. When the vibration load increases, the spring height decreases, the cavity volume decreases, the spring stiffness increases, and the effective bearing area of ​​the air column in the cavity increases, thereby improving the bearing capacity. Conversely, when the vibration load decreases, the spring height increases, the cavity volume increases, the spring stiffness decreases, and the bearing capacity decreases. In this way, the air spring can smoothly and flexibly transmit the vibration load and effectively control the amplitude.

[0054] Furthermore, air springs can be divided into three types according to the structure of the airbag: bladder type, membrane type and composite type: bladder type air spring: It is composed of a rubber airbag with cords and compressed air enclosed therein. The inner layer of the airbag is made of airtight rubber, while the outer layer is made of oil-resistant rubber. The airbag is generally made of two sections, but there are also single sections, three or four sections. The more sections there are, the better the elasticity, but the sealing is relatively poor. There is a steel waist ring between the sections to prevent radial expansion and mutual friction between the two sections. Membrane type air spring: Its enclosed airbag is composed of a rubber diaphragm and a metal pressing part. Compared with the bladder type, the membrane type air spring has a more ideal elastic characteristic curve, a smaller stiffness, a lower natural vibration frequency of the vehicle body, and a smaller size, which is convenient for arrangement on the vehicle and is mostly used in cars. Composite air spring: A type between the bladder type and the membrane type, which combines the advantages of the above two air springs, has a lower spring stiffness, but a complex manufacturing process.

[0055] In the present application, there is no restriction on the type of air spring, and the specific setting should be selected according to the use requirements of the device, so as to improve the applicability and scope of application of the device to meet the user's use requirements.

[0056] Optionally, the pump assembly 10 further includes a compression pump 13, the first air inlet 11 and the first air outlet 12 are respectively connected to the compression pump 13, and the compression pump 13 is used to compress the gas in the first air inlet 11. This can improve the gas delivery efficiency to meet the operation requirements of the device.

[0057] Optionally, the gas circuit block assembly 20 further includes a filter 26, one end of the filter 26 is connected to the first interface 21, and the other end of the filter 26 is connected to the first air inlet 11. The main function of the gas filter 26 is to remove various impurities in the air, including dust, particles, harmful gases, etc. These impurities may have an adverse effect on the normal operation of the device. Through the filtering effect of the filter 26, the quality of the air can be ensured to meet the use requirements of the device.

[0058] Optionally, the gas circuit block assembly 20 further includes a pressure sensor 27, and a pressure sensor 27 is provided between the first interface 21 and the shock absorber interface. The pressure change in the pipeline is sensed by a sensitive element (such as a diaphragm, a spring, a piston, etc.), and the change is converted into an electrical signal output, thereby achieving real-time monitoring of the pipeline pressure to ensure the safety of the pipeline during operation.

[0059] In the present application, the compressor can realize an open system mode, an open system boosting mode, and a closed system mode.

[0060] Implementation method of open system mode: After the gas circuit block assembly 20 starts working, the second air inlet 23 inhales air from the outside, passes through the second interface 22 and the first air inlet 11, and the atmosphere is compressed in the pump body assembly 10 and discharged from the first air outlet 12, and enters the gas circuit block assembly 20 through the second interface 22, and then passes through the dryer 40. After the gas is dried by the dryer 40, a channel is provided in the gas circuit block, and a control valve 25 is correspondingly provided on the channel, which corresponds to the third interface 31, the fourth interface 32, the fifth interface 33, the sixth interface 34, and the gas tank interface 35, respectively. The third interface 31, the fourth interface 32, the fifth interface 33, and the sixth interface 34 correspond to the interfaces of the first shock absorber 61, the second shock absorber 62, the third shock absorber 63 and the fourth shock absorber 64, and the gas tank interface 35 is connected to the storage tank. The gas tank 50 and the corresponding control valve 25 can be opened to replenish air to the corresponding shock absorber or the gas tank 50, and the control valve 25 can be closed after the specified pressure is reached; the gas at a certain pressure is stored in the gas tank 50. When the shock absorber needs to be inflated, and the air pressure in the gas tank 50 is higher than the internal pressure of the shock absorber, the shock absorber can also be directly inflated by the gas tank 50 without the compression pump 13 compressing the gas. It is only necessary to open the gas tank 50 and the corresponding shock absorber control valve 25; when the shock absorber needs to be lowered to exhaust, the pump body is not started and the airway pressure in the airway block is normal pressure. The air pressure in the shock absorber is much higher than the internal pressure of the airway. After the control valve 25 is opened, the gas in the shock absorber is automatically discharged through the pressure difference. After the exhausted gas flows back through the dryer 40, the control valve 25 corresponding to the second air outlet 24 needs to be opened, and the gas can be discharged from the second air outlet 24.

[0061] The method for realizing the boost mode of the open system is that when the air pressure in the air tank 50 is lower than the internal pressure of the shock absorber, the shock absorber needs to be replenished with air and the automatic inflation by pressure difference cannot be realized. It is necessary to start the compression pump 13 to compress the gas for replenishment. If the air is compressed and replenished from normal pressure, the replenishment time is long and the energy consumption is high. In order to save energy and shorten the replenishment time, the gas with a certain air pressure in the air tank 50 is returned to the pump body assembly 10 through the air intake pipe for re-compression, and then goes to the designated shock absorber after compression, which greatly shortens the replenishment time of the shock absorber, reduces the running time of the pump body, reduces the heat generated by the compression pump 13, and reduces energy consumption.

[0062] The closed system mode includes all the modes of the open boost system, and on this basis, there is a mode in which the gas in the shock absorber is compressed back to the gas storage tank 50 through the compression pump 13, so that the gas in the shock absorber is completely circulated internally during the lifting and lowering process, without the need for external air intake, and more energy-saving. The implementation method of this scheme and this mode is as follows: the shock absorber needs to discharge the internal gas when it descends, and the corresponding control valve 25 is opened through the third interface 31, the fourth interface 32, the fifth interface 33, and the sixth interface 34. The gas inside the shock absorber is discharged through the pressure difference. The gas circuit block assembly 20 is also provided with a gas circuit conversion control valve 25 to control the gas flow in the shock absorber to the compression pump 13 for secondary compression. The compressed gas returns to the gas circuit block assembly 20 through the intake pipeline again. The control valve 25 in the gas circuit block switches to control the gas to be stored in the gas storage tank 50, so that the compressed gas circulates inside the pump body assembly 10 and the gas circuit block assembly 20, reducing the working time of the compression pump 13, reducing energy consumption, and increasing the service life of the product.

[0063] According to a second aspect of the present application, an air suspension assembly is provided, comprising the above-mentioned compressor.

[0064] Optionally, the air suspension assembly further includes an air tank 50, which is connected to the air tank interface 35, and a control valve 25 is further provided between the air tank interface 35 and the first interface 21, and the control valve 25 is used to conduct or block the air tank interface 35 and the first interface 21. In this way, the gas in the air tank 50 can be delivered to the pump body assembly 10 to meet the use requirements of the device.

[0065] According to a third aspect of the present application, a vehicle is also provided, comprising the above air suspension assembly.

[0066] The compressor of the embodiment of the present application includes: a pump body assembly 10, having a first air inlet 11 and a first air outlet 12; an air circuit block assembly 20, having a first interface 21, a second interface 22, a second air inlet 23, a second air outlet 24 and a plurality of control valves 25, the second air inlet 23, the first interface 21, the first air inlet 11, the first air outlet 12, and the second interface 22 are connected in sequence to form an air inlet pipeline, the air inlet pipeline is used to transport gas to the pipeline in the air circuit block assembly 20, the second air outlet 24 is used to discharge the gas in the pipeline in the air circuit block assembly 20, and the control valve 25 is used to conduct or block the pipeline in the air circuit block assembly 20. Through the above technical scheme, the second air inlet 23, the first interface 21, the first air inlet 11, the first air outlet 12, and the second interface 22 are connected in sequence to form an air inlet pipeline, so that gas can be delivered to the pipeline in the air circuit block assembly 20. At the same time, the second air outlet 24 is used to discharge the gas in the pipeline in the air circuit block assembly 20, and the pipeline in the air circuit block assembly 20 is opened or blocked by the control valve 25. In this way, by adding valves or subtracting valves to design different air circuits, an open mode, an open boost mode, and a closed mode can be realized, thereby diversifying the modes of the compressor and simplifying the switching, so that the development cost of the compressor is low to meet the user's usage needs.
