Description

Technical Field

[0001] This invention relates to the field of air springs, and more specifically to an integrated intelligent air spring. Background Technology

[0002] Cars have become a common means of transportation, and people didn't have high expectations for them in the past. However, in recent years, people's demands have increased, especially regarding comfort. As the most direct manifestation of comfort, the shock absorption effect of seats is of utmost concern to users.

[0003] To address this issue, researchers have proposed various vibration reduction solutions, including air springs. Air springs generally offer better vibration reduction than other springs, but they require various sensors and air valves to achieve this effect, which means they occupy a larger area. Furthermore, the numerous and complex components make maintenance more difficult and increase the risk of damage to individual parts. Summary of the Invention

[0016] Preferably, the solenoid valve is used to control the inflation and deflation of the integrated intelligent unit, and the solenoid valve includes two valve covers, two valve blocks, a valve stem, a fifth airflow channel, a return end, and a solenoid valve control end;

[0092] Specifically, the solenoid valve 6 is used to control the filling and discharging of gas inside the integrated intelligent unit 12;

[0093] Specifically, the temperature sensor 7, the pressure sensor 8, and the acceleration sensor 9 are used to detect the state of the gas inside the integrated intelligent unit 12;

[0094] Specifically, the height acquisition device 10 is used to detect the distance between the bottom of the integrated intelligent unit 12 and the reflector 10-2;

[0095] Specifically, the ECU is used to control the operation of each module of the entire integrated intelligent unit 12.

[0096] It is evident that this integrated intelligent unit, which integrates various components together, can effectively protect each component. Because it is integrated, it occupies less space, freeing up more space for other modules.

[0097] In some embodiments of the present invention Figure 1 A perspective view of an integrated smart unit according to an embodiment of the present invention is shown, such as Figure 1 As shown, the connector 1 is used to provide current to the integrated intelligent unit 12 as a whole, and to connect the integrated intelligent unit 12 with the external system to realize the communication function.

[0098] As can be seen, this connector can not only power the entire integrated intelligent unit, but also connect to an external control unit to control or adjust parts or the whole of the integrated intelligent unit.

[0099] In some embodiments of the present invention, it remains as Figure 1 As shown, the air inlet 2 is used to provide gas to the integrated intelligent unit 12; the sharing end 3 can connect the integrated intelligent unit 12 to an external inflation module to achieve gas exchange between the two; the exhaust end 4 is used to discharge the gas inside the integrated intelligent unit 12; and the inflation end 5 is used to fill other modules with the gas in the integrated intelligent unit 12.

[0100] As can be seen, this integrated intelligent unit can not only inflate and deflate, but its shared terminal setting can also enable multiple modules to inflate and deflate simultaneously, maintaining balance, while reducing the number of integrated intelligent units and saving costs.

[0101] In some embodiments of the present invention Figure 3 A cross-sectional view of a control valve (in a silent state) according to an embodiment of the present invention is shown, as follows. Figure 3 As shown, the solenoid valve 6 is used to control the inflation and deflation of the integrated intelligent unit 12. The solenoid valve 6 includes two valve covers 6-1, two valve blocks 6-2, a valve stem 6-3, a fifth airflow channel 6-4, a return end 6-5, and a solenoid valve control end 6-6.

[0102] Specifically, the valve stem 6-3 is partially provided with four sealing rings, including a first sealing ring 6-3-1, a second sealing ring 6-3-2, a third sealing ring 6-3-3, and a fourth sealing ring 6-4-4;

[0103] Specifically, the return end 6-5 includes a valve sleeve 6-5-1, a first limiting block 6-5-2, a second limiting block 6-5-3, a third limiting block 6-5-4, and a spring 6-5-5. The return end 6-5 is used to control the return of the valve stem 6-3.

[0104] Specifically, the solenoid valve control terminal 6-6, according to the instructions sent by the ECU11, controls the valve stem 6-3 to move left and right in the fifth airflow channel 6-4, thereby realizing the inflation and deflation functions of the integrated intelligent unit 12.

[0105] As can be seen, the solenoid valve control unit can control the integrated intelligent unit to complete the inflation and deflation functions.

[0106] In some embodiments of the present invention Figure 6 A cross-sectional view of the sensor integration end according to an embodiment of the present invention is shown, such as... Figure 6 As shown, the temperature sensor 7 is used to detect the internal temperature of the integrated intelligent unit 12, and then sends the detection result to the height acquisition device 10 and the ECU 11.

[0107] As can be seen, this integrated intelligent unit can detect the internal gas temperature at any time to ensure the accuracy of the data collected by the height acquisition device. At the same time, it sends the detected temperature to the ECU, which helps the ECU to regulate the internal temperature of the integrated intelligent unit according to the preset program.

[0108] In some embodiments of the present invention, it remains as Figure 6 As shown, the pressure sensor 8 is used to detect the internal pressure of the integrated intelligent unit 12, and then sends the detection result to the height acquisition device 10 and the ECU 11.

[0109] As can be seen, this integrated intelligent unit can detect the internal gas pressure at any time to ensure the accuracy of the data collected by the height acquisition device. At the same time, it sends the detected pressure to the ECU, which helps the ECU to regulate the internal pressure of the integrated intelligent unit according to the preset program.

[0110] In some embodiments of the present invention Figure 7 A perspective view of a height acquisition device according to an embodiment of the present invention is shown, such as... Figure 7 As shown, the height acquisition device 10, in conjunction with the ECU 11, can detect the distance between the bottom of the integrated intelligent unit 12 and the reflector 10-2. The height acquisition device 10 includes a transmitter 10-1, a reflector 10-2, an image acquisition device 10-3, and an image processor 10-4.

[0111] Specifically, the transmitter 10-1 is used to transmit light signals to the reflector 10-2 and send the parameters of the transmitted light signals to the ECU 11;

[0112] Specifically, the reflector 10-2 is used to reflect the optical signal emitted by the transmitter 10-1;

[0113] Specifically, the image acquisition device 10-3 is used to acquire image information of the image formed by the light signal arriving at the surface of the reflector 10-2, and send the image information to the image processor 10-4;

[0114] Specifically, the image processor 10-4 is used to receive image information sent by the image acquisition unit 10-3, calculate the brightness value of the image based on the image information, and send the brightness value to the ECU 11. The ECU 11 calculates the distance between the transmitter 10-1 and the reflector 10-2 based on the brightness value according to a preset program.

[0115] As can be seen, the integrated intelligent unit can detect the height of its surrounding space at any time and send the detection results to the ECU. According to the preset program, the intelligent integrated unit can complete the inflation and deflation functions.

[0116] In some embodiments of the present invention, it remains as Figure 3 and Figure 5 As shown, the ECU11 is used to receive various signals sent by the temperature sensor 7, the pressure sensor 8, the acceleration sensor 9, the height acquisition device 10, and the external control unit, and then process these signals according to a preset program, and send corresponding instructions to each module of the integrated intelligent unit 12 respectively.

[0117] Specifically, when the ECU11 issues a silence command, the solenoid valve control terminal 6-6 no longer controls the valve stem 6-3, and the valve stem 6-3 returns to its initial position under the action of the spring 6-5-5. At this time, the second sealing ring 6-3-2 separates the first airflow channel 2-1 from the second airflow channel 3-1, and the third sealing ring 6-3-3 separates the second airflow channel 3-1 from the third airflow channel 4-1.

[0118] Specifically, when the ECU11 issues an inflation command, the solenoid valve control terminal 6-6 controls the valve stem 6-3 to move to the right. At this time, the first airflow channel 2-1 is connected to the second airflow channel 3-1, and the third sealing ring 6-3-3 separates the second airflow channel 3-1 from the third airflow channel 4-1.

[0119] Specifically, when the ECU11 issues an exhaust command, the solenoid valve control terminal 6-6 controls the valve stem 6-3 to move to the left. At this time, the second sealing ring 6-3-2 separates the first airflow channel 2-1 from the second airflow channel 3-1, and the second airflow channel 3-1 is connected to the third airflow channel 4-1.

[0120] As can be seen, the ECU can adjust the gas filling and exhaust functions inside the integrated intelligent unit in a timely and accurate manner according to the data fed back by each module and the preset program.

[0121] In some embodiments of the present invention Figure 2 A topless perspective view of an integrated intelligent unit according to an embodiment of the present invention is shown, as follows. Figure 2 , Figure 3 and Figure 6 As shown, the gas inside the external inflation module can be directly fed into the second airflow channel 3-1 via the shared end 3;

[0122] Specifically, the gas in the first airflow channel 2-1 and the third airflow channel 4-1 can be directly merged into the second airflow channel 3-1 in the states of inflation and deflation, respectively.

[0123] Specifically, the gas in the second airflow channel 3-1 can be channeled into the inflation end 5 through the fourth airflow channel 5-1.

[0124] It is evident that the state of the gas in the space where the integrated intelligent unit is located is almost identical to the state of the gas in the external modules connected to the shared terminal.

[0125] In some embodiments of the present invention, it remains as Figure 3 As shown, when the integrated intelligent unit 12 is in a silent state,

[0126] Specifically, the gas in the air inlet 2 enters the first airflow channel 2-1, but is restricted by the second sealing ring 6-3-2 from entering the second airflow channel 3-1 to complete the inflation;

[0127] Specifically, the gas gathered in the second airflow channel 3-1 is restricted by the third sealing ring 6-3-3 and cannot enter the third airflow channel 6-3-3 to complete the exhaust.

[0128] In some embodiments of the present invention Figure 4 A cross-sectional view of a control valve (in a charged state) according to an embodiment of the present invention is shown, as follows. Figure 4 As shown, when the integrated intelligent unit 12 is in an inflated state,

[0129] Specifically, the gas in the air inlet 2 enters the first airflow channel 2-1, and is not restricted by the second sealing ring 6-3-2, so it can directly enter the second airflow channel 3-1, and finally enter the inflation end 5 and the shared end 3 respectively;

[0130] Specifically, the gas inside the second airflow channel 3-1 is restricted by the third sealing ring 6-3-3 and cannot enter the third airflow channel 4-1 to enter the exhaust end.

[0131] In some embodiments of the present invention Figure 5 A cross-sectional view of the control valve (exhaust state) according to an embodiment of the present invention is shown, such as... Figure 5 As shown, when the integrated intelligent unit 12 is in the exhaust state,

[0132] Specifically, the gas in the air inlet 2 enters the first airflow channel 2-1, but is restricted by the second sealing ring 6-3-2 from entering the second airflow channel 3-1 to complete the inflation;

[0133] Specifically, the gas gathered in the second airflow channel 3-1 is not restricted by the third sealing ring 6-3-3 at this time, and can directly enter the third airflow channel 4-1, and then be discharged to the outside through the exhaust end 4 to complete the exhaust.

[0134] It is evident that the second and third sealing rings can effectively control the inflation and deflation of the gas in the space where the integrated intelligent unit is located.

[0135] Example 2:

[0136] According to another aspect of the present invention, an intelligent integrated air spring 14 is designed. Figure 8 A perspective view of an air spring without integrated smart unit according to an embodiment of the present invention is shown. Figure 9 A perspective view of an integrated smart air spring according to an embodiment of the present invention is shown, such as Figure 8 and Figure 9 As shown, the integrated intelligent air spring 14 includes an air spring 13 and an integrated intelligent unit 12. The air spring 13 has a groove on its top, and the integrated intelligent unit 12 can be adaptively placed into the groove.

[0137] It is evident that this integrated intelligent air spring combination can effectively solve the problems of sensors used in conjunction with air springs having a large footprint, being easily damaged, and being inconvenient to maintain.

[0138] In summary, this integrated intelligent unit combines multiple sensors, solenoid valve control terminals, and height acquisition devices, saving more space. Because it's integrated, the damage rate is reduced, and its orderly arrangement makes maintenance extremely convenient. The integrated intelligent air spring equipped with this unit also possesses all the advantages of the integrated intelligent unit. Furthermore, the integrated intelligent unit is directly embedded in the top groove of the air spring, further saving space and protecting the various components of the integrated intelligent unit from damage.
