Description

Shock absorber with electronic switching mode and its gas cylinder

The new model relates to a shock absorber for a vehicle, in particular to a shock absorber with an electronic switching mode and a gas cylinder thereof.

The magnetorheological shock absorber changes the viscosity of the magnetic fluid by controlling the magnitude of the current, so that the damping force of the magnetic fluid changes, so that the magnetorheological shock absorber can be controlled by a button on the driver's seat during driving. The shock absorption force of the shock absorber (that is, the hardness of the shock absorber), has both good driving control and riding comfort, so it is deeply loved by consumers.

However, the above-mentioned magnetorheological shock absorbers are relatively expensive to manufacture, so they are more commonly found in high-priced luxury cars or supercars, and are not easily popularized in the general consumer market. In addition, because the magnetic fluid contains tiny metal particles, it is easy to cause the shock absorber element to wear and leak liquid, so that consumers need to replace the magnetorheological shock absorber frequently, which will lead to increased maintenance costs. When consumers switch to a common mechanical shock absorber in order to reduce maintenance costs, because the mechanical shock absorber cannot adjust its hardness during vehicle driving, the button on the driver's seat loses its original function. , there is still room for improvement.

Therefore, the purpose of the present invention is to provide a gas cylinder with a shock absorber with an electronic switching mode, which can improve the service life and can switch the degree of softness and hardness during driving.

Therefore, the novel gas cylinder with shock absorber with electronic switching mode includes a gas cylinder body, a piston, a cover and an electronic control device.

The gas cylinder body includes an inner surface surrounding and defining an accommodating space. The piston is movably disposed in the accommodating space of the gas cylinder body, and the accommodating space is divided into a damping chamber and an air storage chamber, the damping chamber is suitable for the flow of damping liquid therebetween, and the air storage chamber is suitable for filling gas. The cover is arranged on the gas cylinder body and is used to close the gas storage chamber.

The electronic control device is disposed in the air storage chamber, and the air storage chamber is divided into a first chamber and a second chamber, and a communication port is formed between the first chamber and the second chamber, The electronic control device includes a moving rod group and an electromagnetic group. The moving rod set has a stopper for closing the communication port. The electromagnetic group is excited by electricity to control the moving rod group to move between a closed position and an open position. When the moving rod group is in the closed position, the stopper blocks the communication port, and when the moving rod group is in the closed position In the open position, the stopper is separated from the communication port, and the first chamber is spatially communicated with the second chamber through the communication port.

Another object of the present invention is to provide a shock absorber with an electronic switching mode which can improve the service life and can switch the degree of softness and hardness during driving.

Therefore, the new type of shock absorber with electronic switching mode includes a shock absorber body and the gas cylinder as described above.

The shock absorber body is suitable for allowing damping fluid to flow inside, and the shock absorber body includes an adjustment button for adjusting the damping segment. The gas cylinder is connected to the shock absorber body and allows the damping liquid to flow therebetween and makes the damping liquid push the piston to compress the gas in the gas storage chamber to dampen the shock.

The function of the new type is: by electronically controlling the coil to be energized or not energized, so that the moving rod group moves between the closed position and the open position, the air pressure change speed can be changed to switch the hardness of the shock absorber. The electronic control device of the new type can switch the softness and hardness of the shock absorber during driving, and compared with the existing magnetorheological shock absorber, the structure is simple and not easy to be damaged, so the service life can be improved and the maintenance cost can be reduced.
