Description

A suspension gap elimination device and gap elimination method using a double roller structure

technical field

The invention relates to the field of automobile seat manufacturing, in particular to a suspension gap elimination device and a gap elimination method using a double-roller structure. The device is suitable for all automobile seats that require suspension vibration reduction.

Background technique

Since the reform and opening up, especially in recent years, my country's automobile industry has developed strongly. China has become the third country after the United States and Japan to produce more than 10 million vehicles per year, and has entered the ranks of countries with tens of millions of vehicles.

With the advancement of science and technology and the development of the economy, people put forward higher requirements for the safety and quality of automobiles, especially for the comfort of seats when driving and riding. As we all know, the main function of a car seat is to support the weight of the occupant, ease the vibration and impact transmitted by the vehicle body, and provide a comfortable and safe riding environment for the occupant.

At present, most of the sliding parts of truck suspension seats are single pulley or single slider. One of the most prominent problems in the installation form of this structure is that during long-term use, due to the single pulley or single slider During the working process, it is sliding friction, the sliding resistance is large, and the parts are severely worn, resulting in a lateral gap between the parts, and the seat has a large amount of lateral vibration. Since the occupant is far more sensitive to the lateral vibration than the longitudinal vibration, the lateral vibration will have a negative impact on the seat. The body of the occupant causes great harm, and this problem directly affects the occupant's driving experience in the senses. In addition, the structure in which the above-mentioned sliding part is a single pulley or a single slider is difficult to install during the installation process, and the problem of difficult assembly due to part manufacturing errors cannot be eliminated; moreover, if it is guaranteed that the single pulley or single slider can be installed on the C-shaped In the chute, it is unavoidable that there is a lateral gap between the single pulley or single slider and the C-shaped chute, which will still affect the use of end customers. At the same time, if the C-shaped chute is deformed, the suspension seat will inevitably shake laterally. Therefore, it is extremely urgent to avoid the occurrence of this shaking on the suspension seat.

Contents of the invention

The purpose of the present invention is to solve the problems of difficult assembly, large sliding resistance, easy wear and tear of parts in the existing single pulley or single slider structure, and to propose a suspension gap using a double roller structure.

Another object of the present invention is to provide a suspension gap elimination method using a double-roller structure, which specifically includes the following steps:

(1) Install the spring supporting piece in the C-shaped chute of the suspension seat, make the top surface of the spring supporting piece fit the top surface of the C-shaped chute, and reserve a space between the bottom surface and the bottom surface of the C-shaped chute. 1-1.5mm gap;

(2) Install the inner and outer rollers on the two ends of the horizontal axis of the suspension seat in sequence from the inside to the outside, contact the top of the outer roller with the top surface of the spring support piece, and contact the bottom of the inner roller with the inner roller of the spring support piece surface contact;

(3) According to the installation method of step (1) and step (2), respectively assemble the two horizontal shafts of the suspension seat.

Advantage and beneficial effect of the present invention are:

1. The gap elimination device of the present invention has simple structure, convenient assembly, small space occupation, and high application flexibility. It can absorb the sloshing amount without requiring additional space in the existing C-shaped chute, and can Applies to any truck seat with suspension.

2. Due to the pre-deformed spring support plate structure used in the gap elimination device of the present invention, it can effectively solve the gap in the initial stage of assembly, and can effectively avoid the gap caused by plastic deformation and wear during use, which is very The problem of large amount of lateral swaying of the existing seat is well solved.

3. The gap elimination device of the present invention adopts double rollers, the outer roller and the inner roller cooperate with the spring support piece and the C-shaped chute respectively, the inner roller plays a supporting role, and the outer roller is used for rolling, ensuring that the suspension seat During the movement, the friction between the roller and the C-shaped chute is rolling friction, which reduces friction, reduces sliding resistance, and reduces wear of parts.

4. When the spring supporting piece in the gap eliminating device of the present invention is installed on the C-shaped chute, there should be a certain gap with the bottom surface of the C-shaped chute. Unnecessary deformation of the C-shaped chute during the process.
