Description

Technical Field

[0001] The invention relates to the field of automobile seat accessories, and in particular to an integrated intelligent unit, which is mainly used for air springs. Background Art

[0002] In order to provide users with a more comfortable experience, existing air springs are connected to a variety of components and sensors, such as distance sensors, temperature sensors, acceleration sensors, etc., which are used to detect the working environment around the air spring and changes in related data in its own working process. By analyzing the data, the air spring is controlled to inflate and deflate to achieve the expected state.

[0003] As the number of components connected to air springs continues to increase, in addition to taking up a large amount of space themselves, the connection of wiring harnesses and the use of connectors will make early assembly and later maintenance more complicated and difficult. The various magnetic fields generated by the wiring harnesses themselves will overlap or interfere with each other, causing many components to fail to operate normally. The detected data will deviate from the actual data, and the electrical signals transmitted by the wiring harnesses themselves and the electromagnetic waves emitted by the components themselves will also be greatly interfered, making it impossible to accurately adjust the working state of the air springs in real time.

[0004] In order to solve these problems, an integrated intelligent unit was designed, which integrates the components in an orderly manner without affecting the functions of each component. It not only improves the space utilization, but also solves the various production and maintenance costs caused by "chaos", and effectively weakens the various signal interferences caused by the wiring harness layout. Summary of the invention

[0074] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0075] Embodiment 1:

[0076] According to one embodiment of the present invention, a new integrated intelligent unit 1 is designed. Figure 2 The cross-sectional view of the new integrated intelligent unit solenoid valve in the no-command state is shown. Figure 3 The cross-sectional diagram of the new integrated intelligent unit mechanical valve in the no-command state is shown. Figure 1 , Figure 2 , Figure 3 As shown, the novel integrated intelligent unit 1 includes a shared port 2, an exhaust port 3, an air inlet 4, a plug connector 5, a first mechanical valve 6, a second mechanical valve 7, a first solenoid valve 8, a second solenoid valve 9, a control unit 10, an information collection unit 11, a distance sensor 12, an air charging port 13, an air flow channel 14, a housing 15, and a sealing ring 16;

[0077] Specifically, the first mechanical valve 6 includes an end cover 17, a spring 18, a first support cover 6-1, a first mechanical valve core 6-2, and a sealing ring 16, and the second mechanical valve 7 includes an end cover 17, a spring 18, a second support cover 7-1, a second mechanical valve core 7-2, and a sealing ring 16. The first mechanical valve 6 and the second mechanical valve 7 are essentially the same and are the same mechanical valves;

[0078] Specifically, the first solenoid valve 8 includes a filter 20, an electromagnetic coil 19, a first air leakage port 8-1, a first electromagnetic valve core 8-2, a spring 18, a first fixed end 8-3 and a sealing ring 16, and the second solenoid valve 9 includes a filter 20, an electromagnetic coil 19, a second air leakage port 9-1, a second electromagnetic valve core 9-2, a spring 18, a second fixed end 9-3 and a sealing ring 16. The first solenoid valve 8 and the second solenoid valve 9 are essentially the same and are the same solenoid valves;

[0079] Specifically, the air flow channel 14 includes a first air flow channel 14 - 1 , a second air flow channel 14 - 2 , a third air flow channel 14 - 3 , and a fourth air flow channel 14 - 4 .

[0080] It can be seen that the integrated intelligent unit basically integrates various functional parts connected to the existing air spring, improves space utilization, and only requires a small space to have almost all functions. At the same time, it also has its own unique set of control valves, which can realize real-time control of inflation and exhaust.

[0081] In some embodiments of the present invention, Figure 1 A three-dimensional diagram of a new integrated intelligent unit is shown. Figure 1 As shown, the plug connector 5 can be connected to an external power source alone to provide voltage only, and the plug connector 5 can also be connected to other control terminals to provide power and send various control signals to the new integrated intelligent unit 1.

[0082] It can be seen that in addition to its own regulation, the integrated intelligent unit can also achieve external regulation through the plug connector, and can manually control inflation and exhaust. The design of the plug connector is also conducive to later upgrades, further enhancing the functions of the integrated intelligent unit.

[0083] In some embodiments of the present invention, Figure 2 As shown, the information acquisition unit 11 is used to continuously and uninterruptedly collect the spatial information of the new integrated intelligent unit 1. The information acquisition unit 11 can be a sensor group or other components that can collect relevant information. The information collected by the information acquisition unit 11 includes but is not limited to temperature, humidity, pressure, vibration frequency, acceleration and gyroscope. The information acquisition unit 11 will send each piece of collected information to the control unit 10 in real time in the form of a signal.

[0084] It can be seen that the information acquisition unit set up by the integrated intelligent unit is similar to the various sensors in the existing air springs, and can collect various information in the space where the integrated intelligent unit is located. This integrated design can effectively solve the problem of low space utilization when sensors are set up separately. At the same time, because it is an integrated design, there is no need to lay out lines on a large scale, and it can also reduce the influence of the magnetic field and electric field generated by the wiring harness on sensor data acquisition.

[0085] In some embodiments of the present invention, Figure 4 The control diagram of the new integrated intelligent unit is shown as Figure 4 As shown, the control unit 10 controls the working states of the first solenoid valve 8, the second solenoid valve 9 and other components in real time according to a preset program based on the signal sent by the information acquisition unit 11, the height information detected by the distance sensor 12 and the control signal sent by the plug connector 5.

[0086] It can be seen that the integrated intelligent unit has independent data processing capabilities and can control the working status of each component of the integrated intelligent unit in real time based on various information received in real time.

[0087] In some embodiments of the present invention, Figure 1 As shown, the shared port 2 is used to connect the novel integrated intelligent unit 1 and other inflatable working elements to achieve synchronous inflation and exhaust of gases in both. The shared port 2 can also be sealed with a sealing cover when not in use.

[0088] It can be seen that the integrated intelligent unit can control multiple components to inflate and exhaust at the same time, and can be sealed with a sealing cover when not in use without affecting the normal operation of other components.

[0089] In some embodiments of the present invention, Figure 4 As shown, the novel integrated intelligent unit 1 has three working states, namely, no-instruction state, inflation state and exhaust state.

[0090] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, when the novel integrated intelligent unit 1 enters the no-instruction state, the control unit 10 does not send any instructions to the first solenoid valve 8 and the second solenoid valve 9;

[0091] Specifically, the first electromagnetic valve core 8-2 is located in the initial position under the action of the spring force. At this time, the gas flowing out of the first airflow channel 14-1 cannot flow into the second airflow channel 14-2 through the first fixed end 8-3, and the gas in the second airflow channel 14-2 can flow into the filter plate 20 through the first air leakage port 8-1 and be discharged. The first mechanical valve core 6-2 is not affected by the gas in the second airflow channel 14-2 and cannot push up the first support cover 6-1. The first support cover 6-1 moves downward under the action of the spring 18 to close the connection between the air inlet 4 and the fourth airflow channel 14-4 to prevent inflation.

[0092] Specifically, the second solenoid valve core 9-2 is located in the initial position due to the spring force. At this time, the gas flowing out of the first airflow channel 14-1 cannot flow into the third airflow channel 14-3 through the second fixed end 9-3, and the gas in the third airflow channel 14-3 can flow into the filter plate 20 through the second air leakage port 9-1 and be discharged. The second mechanical valve core 7-2 is not affected by the gas in the third airflow channel 14-3 and cannot lift up the second support cover 7-1. The second support cover 7-1 is moved downward by the spring 18 to close the connection between the exhaust port 3 and the fourth airflow channel 14-4 to prevent exhaust.

[0093] It can be seen that when the integrated intelligent unit does not receive any instructions, the two solenoid valves restrict the entry of gas in the air inlet, thereby restricting the operation of the two mechanical valves, and neither inflating nor exhausting.

[0094] In some embodiments of the present invention, Figure 5 The cross-sectional diagram of the new integrated intelligent unit solenoid valve charging state is shown. Figure 6 The cross-sectional diagram of the inflation state of the new integrated intelligent unit mechanical valve is shown. Figure 5 and Figure 6 As shown, when the novel integrated intelligent unit 1 enters the inflation state, the control unit 10 sends a start instruction to the first solenoid valve 8, and the control unit 10 sends a closing instruction to the second solenoid valve 9;

[0095] Specifically, when the gas in the air inlet 4 enters the first solenoid valve 8 through the first air flow channel 14-1, the first solenoid valve core 8-2 is moved up by the electromagnetic coil 19 to close the first air leakage port 8-1, and the gas flowing out of the first air flow channel 14-1 flows into the first mechanical valve core 6-2 in the first mechanical valve 6 through the first fixed end 8-3 and the second air flow channel 14-2. The first mechanical valve core 6-2 is moved up by the gas to push open the first support cover 6-1, and the gas in the air inlet smoothly passes through the first mechanical valve 6 and flows into the fourth air flow channel 14-4 and enters the inflation port 13 to complete inflation;

[0096] Specifically, when the gas in the air inlet 4 enters the second solenoid valve 9 through the first airflow channel 14-1, the second solenoid valve core 9-2 is kept in the initial position by the spring force, and the gas flowing in from the first airflow channel 14-1 cannot enter the third airflow channel 14-3 through the second fixed end 9-3, and the gas in the third airflow channel 14-3 is discharged from the filter plate 20 through the second air leakage port 9-1, and the second support cover 7-1 of the second mechanical valve 7 is located in the initial position to limit the gas in the fourth airflow channel 14-4 from flowing into the exhaust port 3 for discharge;

[0097] Specifically, when the inflation port 13 is saturated and cannot be filled with new gas, the gas newly introduced into the fourth air flow channel 14-4 from the air inlet 4 will lift up the second mechanical valve core 7-2, and this part of the newly entered gas will flow into the exhaust port 3 through the end cover 17 of the second mechanical valve 7 and be discharged.

[0098] It can be seen that when the integrated intelligent unit enters the inflation state, the control unit will issue instructions to the two solenoid valves respectively, thereby controlling the opening and closing of the corresponding mechanical valves to achieve the inflation effect; for the problem that excessive inflation of traditional air valves may cause damage to the air valves, the integrated intelligent unit also solves this problem well through its unique design.

[0099] In some embodiments of the present invention, Figure 7 The exhaust state cross-section of the new integrated intelligent unit solenoid valve is shown. Figure 8 The exhaust state profile of the new integrated intelligent unit mechanical valve is shown in FIG. Figure 7 and Figure 8 As shown, when the novel integrated intelligent unit 1 enters the exhaust state, the control unit 10 sends a closing instruction to the first solenoid valve 8, and the control unit 10 sends a starting instruction to the second solenoid valve 9;

[0100] Specifically, when the gas in the air inlet 4 enters the first solenoid valve 8 through the first airflow channel 14-1, the first solenoid valve core 8-2 is kept in the initial position by the spring force, and the gas flowing in from the first airflow channel 14-1 cannot enter the second airflow channel 14-2 through the first fixed end 8-3, and the gas in the second airflow channel 14-2 is discharged from the filter plate 20 through the first air leakage port 8-1, and the first support cover 6-1 of the first mechanical valve 6 is located in the initial position to limit the gas in the charging port 13 from flowing into the fourth airflow channel 14-4;

[0101] Specifically, when the gas in the air inlet 4 enters the second solenoid valve 9 through the first airflow channel 14-1, the second solenoid valve core 9-2 is moved up by the electromagnetic coil 19 to close the second air leakage port 9-1, and the gas flowing out of the first airflow channel 14-1 flows into the second mechanical valve core 7-2 of the second mechanical valve 7 through the second fixed end 9-3 and the third airflow channel 14-3. The second mechanical valve core 7-2 is moved up by the gas to push open the second support cover 7-1, and the gas in the fourth airflow channel 14-4 is discharged through the exhaust port 3 to complete the exhaust.

[0102] It can be seen that when the integrated intelligent unit enters the inflation state, the control unit will issue instructions to the two solenoid valves respectively, thereby controlling the opening and closing of the corresponding mechanical valves respectively to achieve the exhaust effect.

[0103] Embodiment 2:

[0104] According to some embodiments of the present invention, another air spring 21 is designed. Fig. 9 The relationship diagram between the new integrated intelligent unit and the air spring is shown in FIG. Fig. 9 As shown, the air spring 21 includes any one of the novel integrated intelligent units 1 described above.

[0105] In summary, the use of the integrated intelligent unit and air spring can solve the clutter caused by connecting the existing air spring with other necessary components; similarly, this integration can also reduce the floor space, increase space utilization, provide more usage space for other components, and help reduce the size of the product; this integrated design also solves the various problems caused by wiring harness layout, such as cluttered wiring harnesses that are difficult to maintain later, electromagnetic wave interference generated by the wiring harnesses themselves or each other, and data transmission failures caused by wiring harness shedding and aging; similarly, with this integrated design, the more components integrated, the lower the production cost, the lower the damage rate, and the longer the service life.

[0106] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
