Problems solved by technology

Although this suspension control system can improve the stability and comfort of the suspension system, the electronic components in the suspension control system are easily limited by the installation position in the actual application process, so that the control accuracy is not accurate enough and Installation and maintenance are inconvenient; in addition, the circuit layout of electronic components is easily limited by the space of the suspension system itself, and the cost of the suspension control system is relatively high, so that the suspension control system has not been widely used

Embodiment 1

[0032] figure 1 It shows a perspective view of a device for adjusting damping force and height according to an embodiment of the present invention, as shown in figure 1 As shown, a device 10 for adjusting the damping force and height includes a regulating valve 11, the regulating valve 11 includes a damping valve A and a height valve B, the damping valve A and the height valve B are arranged side by side, and the damping valve A and the height valve B communicate with each other , the damping valve A and / or the height valve B are connected with the air source, the damping valve A is connected with the damping force adjustment device of the damping element, the height valve B is connected with the air spring; the height valve B includes a first cylinder B100 and at least one slidable The height control rod B200 arranged in the first cylinder, it can be seen that the height valve B is a linear structure, through the relative displacement of the height control rod B200 and the fi...

Embodiment 2

[0082] Figure 16 It shows a schematic diagram of the functional structure of a seat according to an embodiment of the present invention, as shown in Figure 16 As shown, a seat has at least two relatively movable scissor frame structures (50, 60) and at least one damping element 40 for shock absorption and an air spring 30 for height adjustment, and the seat also includes the damping element The damping force adjustment device and the device 10 for adjusting the damping force and height as shown in Embodiment 1, the damping force adjustment device (not shown) of the damping element 40, the air spring 30, the damping element and the device 10 for adjusting the damping force and height The positions of the four are compatible, and the device 10 for adjusting the damping force and the height is respectively connected with the damping force adjusting device of the damping element and the air spring 30;

[0083] One end of the device 10 for adjusting damping force and height is c...

Embodiment 3

[0087] A vehicle suspension system includes a vehicle body and at least four wheels, at least two damping elements for shock absorption and air springs for height adjustment are arranged between the vehicle body and the wheels, and the vehicle suspension system also includes the damping force of the damping elements The adjusting device and the device 10 for adjusting damping force and height shown in Embodiment 1, the damping force adjusting device of the damping element, the air spring, the damping element and the device 10 for adjusting the damping force and the height are adapted to the positions of the four, and the damping is adjusted The force and height devices 10 are respectively connected to the damping force adjustment device of the damping element and to the air spring.

[0088] It can be seen that as long as the height of the vehicle suspension changes, the relative motion between the vehicle body and the wheels can synchronously drive the height control rod and th...

Abstract

The invention discloses a device enabling adjustment of damping force and a height, a seat and a vehicle suspension system. The device enabling adjustment of the damping force and the height comprisesa damp valve and a height valve which are disposed side by side and mutually interconnected. The height valve comprises a first cylinder and at least one height control rod which is arranged in the first cylinder in a sliding manner, wherein through displacement of the height control rod and the first cylinder relative to each other, gas flow connection is generated between an air spring and a gas source or atmosphere, so inflation and deflation of the air spring is realized. The damp valve comprises a second cylinder and at least one damp force control rod which is arranged in the second cylinder in a sliding manner, wherein through displacement of the damp force control rod and the second cylinder relative to each other, gas flow connection is generated between a damp adjustment deviceof a damp component and the gas source and the atmosphere, so the damp force of the damp component can be adjusted. Synchronous driving is realized by the height control rod and the damp force controlrod. Obviously, the device disclosed by the invention realizes synchronous adjustment of the height and the damping force.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a device for adjusting damping force and height, a seat and a vehicle suspension system. Background technique [0002] The existing suspension system mainly includes two control systems of height adjustment and shock absorption adjustment. These two control systems are mutually independent systems and respectively have corresponding control mechanisms. In the manual adjustment mode, it is necessary to press two buttons at the same time to realize the synchronous adjustment of the two control systems, which is inconvenient to operate. In the electronic control mode, the suspension control system based on CDC damper (CDC, Continuous Damping Control) is more commonly used. The suspension control system first uses sensors to collect information and sends the collected information to the electronic control unit. The electronic control unit calculates the air pressure in the air spring ...
