Description

car seat shock absorber

technical field

The invention relates to a car seat shock absorber.

Background technique

With the rapid development of the automobile manufacturing industry and the continuous improvement of automobile manufacturing technology, passengers have higher and higher requirements for ride comfort. Usually, the chassis of a car is equipped with a shock absorber, but the vibration frequency and amplitude of each part of the car are different, so the overall shock absorption of the chassis cannot meet the needs of ride comfort. At present, most mid-to-high-end cars are equipped with independent shock absorbers at the bottom of each seat, but most of the existing shock absorbers are only cushioned by the main spring, and when the spring is compressed and restored to deformation, the passenger's bumpy feeling is obvious. The noise is large, which affects the comfort of passengers when using it, and the protection measures of the shock absorber itself are not perfect, and the life of the shock absorber is short.

In view of the above problems, the patent document with the publication number CN204755696U discloses a novel automobile seat shock absorber. The shock absorber shell is threadedly connected, and the side of the connection between the upper shock absorber shell and the lower shock absorber shell is provided with screws, and the ends of the upper shock absorber shell and the lower shock absorber shell are equipped with buffer pads. The middle parts of the upper shock absorber shell and the lower shock absorber shell are all vertically slid to be provided with connecting rods with the same structure, and the ends of the connecting rods are threaded on the outer sides of the upper shock absorber shell and the lower shock absorber shell. A nut is connected, and the other end of the connecting rod is provided with a pressure plate inside the upper shock absorber shell and the lower shock absorber shell, and the lower middle part of the pressure plate is fixed with a spring fixing boss, and the upper shock absorber A main spring is socketed between the shell and the spring fixing bosses on the upper and lower sides of the lower shock absorber shell, and the upper side of the pressure plate is connected to the gasket through the secondary spring, and the gasket is slidably connected to the connecting rod. The inner top ends of the upper shock absorber shell and the lower shock absorber shell are equipped with a shock absorber, and the shock absorber is slidably connected with the connecting rod.

In the technical solution of the above-mentioned patent document, by setting the auxiliary spring, it can cooperate with the main spring to perform secondary cushioning, and when the gasket squeezes the shock-absorbing pad, the shock-absorbing pad can be used for further elastic buffering to reduce noise , improving the overall comfort and safety of passengers when using it. However, since the active force will always be transmitted along the spring, in the technical solution of this patent, the active force is not transferred to the shell, and the shell is used for shock absorption.

Contents of the invention

The present invention intends to provide a car seat shock absorber, so that the vibration of the car is firstly transmitted to the shock absorber shell by the main spring, and then transmitted to the secondary spring by the shock absorber shell, so that the shock absorber shell is used as the middle of the buffer. body.

The car seat shock absorber in this scheme, the basic scheme is: comprising an upper shock absorber shell and a lower shock absorber shell, the upper shock absorber shell and the lower shock absorber shell are threaded, and the upper shock absorber The middle part of the casing and the lower shock absorber casing is provided with a connecting rod that can slide vertically, and a spring plate is provided on the opposite end of the connecting rod, and a spring fixing protrusion is provided on the spring plate; the lower shock absorber An upper annular boss and a lower annular boss are arranged in the housing of the device, a first buffer plate is arranged between the upper annular boss and the lower annular boss, and one end of the upper annular boss in contact with the first buffer plate is Rubber, the main spring is arranged between the first buffer plate and the spring plate; the second buffer plate is arranged under the spring fixing protrusion in the upper shock absorber shell, and the spring fixing protrusion is connected with the second buffer plate Auxiliary springs are arranged between them.

Working principle and beneficial effects: When the car passes on a bumpy road, the force on the body is first transmitted to the lower connecting rod, and the lower connecting rod transmits the force to the main spring, and the main spring transmits the force to the first buffer The first buffer plate transmits the active force to the lower shock absorber shell through the upper annular boss, and the lower shock absorber shell transmits the active force to the upper shock absorber shell. The upper shock absorber housing transmits the active force to the secondary spring through the second buffer plate, and the secondary spring transmits the active force to the connecting rod. In this embodiment, different from the prior art, the active force is first transmitted to the shock absorber housing through the main spring, and then the active force is transmitted to the secondary spring through the shock absorber housing, avoiding multiple springs in the prior art. Disadvantages of greater vibration when directly connected to the buffer.

Solution 2, as an improvement to the basic solution, the lower part of the spring fixing protrusion is a cylinder, and the upper part is an arc-shaped protrusion. The advantage is that the cylinder adapts to the shape of the spring and can better fix the spring. The arc-shaped protrusion can facilitate the installation of the spring.

Solution 3, as an improvement to solution 2, the arc-shaped protrusion is made of elastic material. The advantage is that when the turbulence is large, the main spring and the auxiliary spring are compressed so that the arc-shaped protrusion contacts the first buffer plate or the second buffer plate, which can play a further buffering role.

Solution 4, as an improvement to the basic solution, a groove is provided on the wall surface of the first buffer plate opposite to the spring fixing protrusion. The advantage is that further positioning of the main spring is possible.

Solution 5, as an improvement to the basic solution, a groove is provided on the wall surface of the second buffer plate opposite to the spring fixing protrusion. The advantage is that further positioning of the secondary spring is possible.
