Description

Technical Field

[0001] This utility model belongs to the field of vehicle seat technology, and in particular relates to an adaptive seat height adjustment system. Background Technology

[0002] In existing vehicles, seat height self-adjustment and comfort adjustment are manually controlled. During driving, drivers often need to bend over and reach out a hand to operate switches to adjust the seat height, increasing the risk of accidents. Furthermore, current automatic seat adjustment mechanisms use plastic parts, which are susceptible to mechanical fatigue and durability issues; over time, the automatic inflation / deflation function fails. Therefore, such seats cannot meet the market's ever-increasing demand for reliability. Summary of the Invention

[0003] The purpose of this invention is to provide a system that can both electrically adjust the seat height and adaptively adjust the seat height.

[0004] The purpose of this utility model is to solve the following problem:

[0005] An adaptive seat height adjustment system includes an external air source and a lower damping frame assembly, an upper damping frame assembly, and a damping airbag on the lower damping frame assembly. The upper damping frame assembly is equipped with an ECU controller, a solenoid valve, and a lifting switch that are electrically connected to each other. The rods of the cross-shaped lifting assembly are equipped with sensors (such as angle sensors and / or acceleration sensors and / or displacement sensors) that measure the tilt angle of the rods and transmit measurement signals to the ECU controller. The external air source is connected to the solenoid valve and the inner cavity of the damping airbag through air pipes. The height of the upper damping frame assembly is controlled by the inflation and deflation of the damping airbag through the lifting switch. The height of the upper damping frame assembly is also controlled by the inflation and deflation of the damping airbag through the angle range set by the ECU controller.

[0006] As a further optimization of the above technical solution, the solenoid valve includes an exhaust solenoid valve and an intake solenoid valve, or the solenoid valve is a solenoid valve that controls the shock-absorbing airbag to not intake when it is exhausting, or not exhaust when it is intake, or not exhaust and not intake when the position is adjustable.

[0007] As a further optimization of the above technical solution, when the ECU controller receives the sensor-detected tilt angle of the rod within the first range (for example, the tilt angle of the rod is relatively small, 5-10 degrees, at which time the seat height is low), the ECU controller controls the solenoid valve to inflate the shock-absorbing airbag, and the height of the shock-absorbing airbag is raised.

[0008] As a further optimization of the above technical solution, when the ECU controller receives the sensor-detected tilt angle of the rod in the second range (for example, the tilt angle of the rod is relatively large, 55-60 degrees, at which time the seat height is relatively high), the ECU controller controls the solenoid valve to exhaust the shock absorber airbag, and the height of the shock absorber airbag is reduced.

[0009] As a further optimization of the above technical solution, when the ECU controller receives the sensor-detected tilt angle of the rod in the third range (for example, the tilt angle of the rod is a moderate 11-54 degrees, at which time the seat height is moderate), the ECU controller controls the solenoid valve to prevent the shock absorber airbag from venting or venting, and the height of the shock absorber airbag remains unchanged.

[0010] As a further optimization of the above technical solution, when the ECU controller receives the sensor-detected tilt angle of the rod in the third range (for example, the tilt angle of the rod is a moderate 11-54 degrees, at which time the seat height is moderate), and the ECU controller receives the control signal of the lifting switch downward, the ECU controller controls the solenoid valve to discharge the gas in the shock-absorbing airbag, and the height of the shock-absorbing airbag is reduced.

[0011] As a further optimization of the above technical solution, when the ECU controller receives the sensor-detected tilt angle of the rod in the third range (for example, the tilt angle of the rod is a moderate 11-54 degrees, at which time the seat height is moderate), and the ECU controller receives the upward signal of the lifting switch, the ECU controller controls the solenoid valve to inflate the shock-absorbing airbag, and the height of the shock-absorbing airbag increases.

[0012] As a further optimization of the above technical solution, the ECU controller detects the disconnection of the IG power supply, controls the intake solenoid valve to close and the exhaust solenoid valve to open, so that the gas in the shock absorber airbag is discharged and the height of the shock absorber airbag is reduced to the minimum.

[0013] As a further optimization of the above technical solution, when the ECU controller receives the sensor-detected lever tilt angle located in the third range (for example, the lever tilt angle is a moderate 11-54 degrees, at which time the seat height is moderate), it will form a memory of any adjusted height.

[0014] As a further optimization of the above technical solution, the ECU controller detects the IG power connection and controls the solenoid valve to inflate the shock-absorbing airbag, raising the height of the shock-absorbing airbag to the memory height of the last adjusted third range (e.g., the tilt angle of the rod is a moderate 11-54 degrees, at which time the seat height is moderate).

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. This utility model utilizes the sensor range value set by the ECU controller to automatically control the inflation and deflation of the shock-absorbing airbag to control the height of the upper shock-absorbing frame assembly, thereby reducing the frequency of manual adjustments and increasing the comfort of the occupant's seat.

[0017] 2. This utility model uses a lifting switch to control the inflation and deflation of the shock-absorbing airbag to control the height of the upper shock-absorbing frame assembly, which can adapt to the special needs of different people for seat height.

[0018] 3. This utility model has a simple structure, convenient operation and adjustment of seat height, and good comfort. Attached Figure Description

The height of the upper damping frame assembly 6 is controlled by the inflation and deflation of the damping airbag 10 through the lifting switch 3. The height of the upper damping frame assembly 6 is controlled by the inflation and deflation of the damping airbag 10 through the angle range value set by the ECU controller 2.

[0023] As a further optimization of the above technical solution, when the ECU controller 2 receives the sensor 5 and the rod tilt angle is in the first range (for example, the rod tilt angle is a small 5-10 degrees, at which time the seat height is low), the ECU controller 2 controls the solenoid valve to inflate the shock-absorbing airbag 10 (equivalent to the exhaust solenoid valve 4 being closed and the intake solenoid valve 12 being opened, thus raising the height of the shock-absorbing airbag 10).

[0024] As a further optimization of the above technical solution, when the ECU controller 2 receives the sensor 5 and the rod tilt angle is in the second range (for example, the rod tilt angle is relatively large, 55-60 degrees, at which time the seat height is relatively high), the ECU controller 2 controls the solenoid valve to exhaust the shock absorber airbag 10 (equivalent to the exhaust solenoid valve 4 opening and the intake solenoid valve 12 closing), and the height of the shock absorber airbag 10 decreases.

[0025] As a further optimization of the above technical solution, when the ECU controller 2 receives the sensor 5 and the rod tilt angle is in the third range (for example, the rod tilt angle is a moderate 11-54 degrees, at which time the seat height is moderate), the ECU controller 2 controls the solenoid valve to prevent the shock absorber airbag 10 from exhausting or inhaling air (equivalent to both exhaust solenoid valve 4 and intake solenoid valve 12 being closed, and the solenoid valve being in the design position of not inhaling or exhausting air), the height of the shock absorber airbag 10 remains unchanged.

[0026] As a further optimization of the above technical solution, when the ECU controller 2 receives the control signal of the lifting switch 3 to move downwards, the ECU controller 2 receives the control signal of the lifting switch 3 to move downwards, and the ECU controller 2 controls the solenoid valve to discharge the gas in the shock-absorbing airbag 10 (equivalent to the exhaust solenoid valve 4 opening and the intake solenoid valve 12 closing, and the solenoid valve being in the position of not intake when exhausting), and the height of the shock-absorbing airbag 10 is reduced.

[0027] As a further optimization of the above technical solution, when the ECU controller 2 receives the signal from the sensor 5 that the tilt angle of the rod is within the third range (for example, the tilt angle of the rod is a moderate 11-54 degrees, at which time the seat height is moderate), and the ECU controller 2 receives the signal of the lifting switch 3 moving upward, the ECU controller 2 controls the solenoid valve to inflate the shock-absorbing airbag 10 (equivalent to controlling the exhaust solenoid valve 4 to close and the intake solenoid valve 12 to open, with the solenoid valve in the position of not exhausting when inhaling), the height of the shock-absorbing airbag 10 increases.

[0028] As a further optimization of the above technical solution, the ECU controller 2 detects that the IG power is disconnected and controls the solenoid valve to close, so that the gas in the shock absorber 10 is discharged (equivalent to the exhaust solenoid valve 4 being open and the intake solenoid valve 12 being closed, with the solenoid valve in the position of not intake when exhausting), and the height of the shock absorber 10 is reduced to the lowest level.

[0029] As a further optimization of the above technical solution, when the ECU controller 2 receives the information from the sensor 5 that the tilt angle of the lever is within the third range (for example, the tilt angle of the lever is a moderate 11-54 degrees, at which time the seat height is moderate), it will form a memory of any adjusted height.
