Vehicle vibration damping buffering seat based on four-bar linkage adjusting mechanism

Abstract

The invention discloses a vehicle vibration damping buffering seat based on a four-bar linkage adjusting mechanism. The vibration damping buffering seat involves a sliding rail assembly, a seat, a mounting side plate, an oil-gas spring and a four-bar linkage adjusting mechanism, wherein the left side and the right side of the seat are mounted on the mounting side plate through the sliding rail assembly, the upper end and the lower end of the four-bar linkage adjusting mechanism are hinged to a vehicle body and the mounting side plate respectively, the upper end and the lower end of the oil-gasspring are hinged to the middle of the four-bar linkage adjusting mechanism and the bottom of the vehicle body respectively, the height of the seat is adjusted by the four-bar linkage adjusting mechanism through expanding and retracting of the oil-gas spring, and the vibration damping, buffering and anti-exploding functions of the seat is realized through the damping force of the oil-gas spring.

Description

technical field [0001] The invention relates to a vehicle component, in particular to a vehicle seat with functions of vibration reduction and impact buffering and greater height adjustment. Background technique [0002] The current engineering vehicles and special vehicles such as tanks and armored vehicles generally only have lifting mechanisms but no shock absorbing mechanisms, especially for tanks and military armored vehicles, which makes the vehicle occupants can not satisfy both the convenience of operation and the ride comfort. First, the adjustment step length of the height adjustment mechanism is relatively large, which cannot meet the needs of passengers of different heights for comfortable driving; second, due to the lack of a vibration damping mechanism, the passengers are subject to greater vibration, greatly reducing fatigue efficiency and combat effectiveness; Third, there is no special anti-explosion design on the seats of most domestic tanks or armored vehi...

AI Technical Summary

Problems solved by technology

[0002] The current engineering vehicles and special vehicles such as tanks and armored vehicles generally only have a lifting mechanism without a shock absorbing mechanism, especially for tanks and military armored vehicles, which makes the vehicle occupants unable to satisfy both the convenience of operation and the ride comfort.

First, the adjustment step length of the height adjustment mechanism is relatively large, which cannot meet the needs of passengers of different heights for comfortable driving; second, due to the lack of a vibration damping mechanism, the passengers are subject to greater vibration, greatly reducing fatigue efficiency and combat effectiveness; Third, there is no special anti-explosion design on the seats of most domestic tanks or armored vehicles, and the seats have poor impact resistance. It has anti-explosion function, but no vibration reduction function; Fourth, some seats are equipped with anti-explosion devices such as expanded tubular energy absorbers or coil spring energy absorbers, but these devices are disposable products. When the vehicle encounters a mine explosion These devices do not provide secondary impact protection against a second impact after impact

[0003] It can be seen that the current passenger seats of tank armored vehicles lack the function of vibration reduction and anti-explosion, and the vibration and shock of the chassis are the main factors affecting the riding comfort, viewing and aiming control efficiency and life safety of the passengers.
