Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive seat suspension technology, and in particular to an anti-slip and noise-reducing automotive seat suspension. Background Technology
[0002] As a key component of car seats, the performance of car seat suspension directly affects the safety and comfort of passengers.
[0003] Currently, existing car seat suspensions have two prominent problems: In terms of anti-slip performance, when the vehicle encounters rapid acceleration, rapid deceleration, or bumpy roads, the seat and suspension system are prone to relative displacement, which not only reduces ride stability but may also cause safety hazards. Traditional suspensions mostly rely on simple mechanical connections and lack dynamic adaptive anti-slip structures, making it difficult to cope with complex road conditions.
[0004] In terms of noise reduction, vibrations and component friction in the suspension system generate continuous noise that is transmitted to the passenger compartment. While existing technologies employ damping elements to reduce vibration, they lack active noise reduction mechanisms. Especially in high-frequency vibration scenarios, noise control is limited, impacting the driving and riding experience. Therefore, developing seat suspensions that combine adaptive anti-slip and active noise reduction functions is of great significance. Utility Model Content

The fixing seat is located at the bottom of the suspension bracket and has a built-in reinforcing rod. The connector connects the fixing seat to the four sets of suspensions.
