Problems solved by technology

However, the front and rear amplitudes at the back of the seat, due to the limitation of the seat structure and its strength, tend to have vibration amplification compared to the seat cushion (such as figure 1 shown), at this time, it is far from enough to rely on the airbag shock absorber under the seat and the backrest sponge to isolate the vibration input from the cab. driving problems, leading to poor driving comfort, which in turn causes driving fatigue and poses safety hazards

Abstract

The invention discloses a commercial vehicle seat vibration reduction system which comprises a base, a back plate, a seat, a first vibration reduction assembly and a second vibration reduction assembly, the seat comprises a cushion and a backrest, the seat is arranged above the base, and the first vibration reduction assembly is installed between the base and the cushion and supports the seat; the back plate is connected to the rear end of the base in a rotatable and adjustable mode and arranged opposite to the back face of the backrest, a sliding block capable of moving in the length direction of the back plate is connected to the back plate, and the second vibration reduction assembly is installed between the back plate and the sliding block. According to the invention, vertical vibration can be filtered, and pitching and back-and-forth vibration can be inhibited.

Description

technical field [0001] The invention belongs to the technical field of automobile seats, and in particular relates to a vibration damping system for a commercial vehicle seat. Background technique [0002] The role of commercial vehicle seats is to filter vibrations and improve the comfort of drivers and passengers during driving, which plays a crucial role in the driving experience. Airbag shock absorbers are usually installed under the driver's seat, and sponges are arranged on the seat cushion and backrest to improve seat vibration damping performance and wrapping. [0003] Commercial vehicles, especially heavy-duty trucks, are used in harsh environments and road conditions, and the cab often has a large amount of front and rear movement or even pitching. However, due to the limitation of the seat structure and its strength, the front and rear vibration amplitudes at the seat back position tend to have vibration amplification compared to the seat cushion (such as figure...
