The magnetorheological fluid shock absorber comprises a fixing part, wherein the fixing part is provided with a sliding part mounting chamber, a shock absorption fluid cavity and a power-off shock absorption runner; a first flow channel sealing part is slidably connected into the sliding part mounting chamber; a first magnetic field generator; the vibration reduction connecting part is provided with an extending part and a piston body; the piston body is provided with a main vibration reduction flow channel, and the cross section area of the main vibration reduction flow channel is larger than that of the power-off vibration reduction flow channel. A main runner on-off control structure; the main flow channel on-off control structure comprises a magnetic part, a blocking piece and a blocking elastic piece, the blocking elastic piece enables the blocking piece to have the trend of blocking the main vibration reduction flow channel all the time, and the blocking piece and the main vibration reduction flow channel are correspondingly arranged; and the second magnetic field generating piece is connected in series with the first magnetic field generating piece and is electrically connected with the first magnetic field generating piece. The hydrogen cylinder protection support comprises a main support body, a hydrogen cylinder installation frame and a magnetorheological fluid shock absorber, and the hydrogen cylinder installation frame is provided with a hydrogen cylinder installation groove.

Description

technical field [0001] The invention relates to the technical field of vibration damping devices, in particular to a magnetorheological fluid damper and a hydrogen bottle protection bracket. Background technique [0002] The existing magnetorheological fluid shock absorber is a device that uses electromagnetic response and based on the input information from monitoring body and wheel motion sensors to respond to road conditions and driving environment in real time to achieve vibration reduction requirements. Magnetorheological liquid is a magnetic soft particle suspension. When the liquid is injected into the electromagnetic coil in the shock absorber piston, the magnetic field of the coil will change its rheological properties (or generate fluid resistance), so that there is no electromechanical control valve, In addition, when the mechanical device is simple, a damping force with rapid response and strong controllability is generated. [0003] Due to the characteristics o...

AI Technical Summary

Problems solved by technology

[0003] Due to the characteristics of the magnetorheological fluid itself, when the circuit of the magnetorheological fluid shock absorber is abnormal, such as the coil of the magnetorheological fluid shock absorber cannot be energized, the damping value of the magnetorheological fluid cannot be changed. The damping value of the rheological fluid is low, and it cannot bear the effect of better vibration reduction and energy consumption
