Description

A rubber spring mechanical suspension structure

technical field

The utility model relates to an automobile seat component, in particular to a rubber spring mechanical suspension structure.

Background technique

Car seats are a key component of a car. There are many kinds of car seat structures, among which mechanical suspension seats are widely used. At present, mechanical suspension seats have the following defects: 1. Due to the limited space inside the seat, it is difficult to arrange metal springs that meet the fatigue requirements; 2. The arrangement of metal springs requires a stiffness adjustment mechanism. manufacturing cost. Therefore be necessary utility model a kind of rubber spring mechanical suspension structure.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art, and provide a rubber spring mechanical suspension structure.

The purpose of this utility model is solved by the following technical solutions: it includes an upper support frame and a lower support frame, and the upper support frame and the lower support frame are connected by a rotating bracket: it is characterized in that: the upper and lower ends of the rotating bracket The front part is fixed with a moving shaft, and the two inner sides of the upper and lower support frames are provided with chute, and the two moving shafts are movably embedded in the chute, and the top of the upper moving shaft is fixed with a rubber block; the upper and lower ends of the rotating bracket The rear portion is fixed with a rotating shaft, and the upper and lower rotating shafts are movably installed in the shaft holes of the upper support frame and the lower supporting frame respectively, and the upper and lower rotating shafts are covered with cylindrical rubber.

The preferred technical scheme of the utility model is: the rubber block is fixed between the front splint and the rear splint, the front splint is fixed with connecting bolts, the rear splint is fixed with a connecting piece, and the connecting piece is composed of two and a half pieces It is formed by connecting circular connecting blocks and bolts. The rotating shaft is covered with a cylindrical rubber, and the cylindrical rubber is covered with a steel sleeve. The front end of the rotating shaft is provided with a flat groove, and the center of the rotating shaft is provided with a screw hole. Slide blocks are fixed on both top ends of the moving shaft, and rotating sleeves are fixed on both top ends of the rotating shaft.

The utility model has the following advantages: 1. The utility model uses a rubber block as a rubber spring which is highly non-linear and therefore does not need to be equipped with a stiffness adjustment mechanism, so the structure is simple and the manufacturing cost is low. 2. The rubber spring is small in size, so it is suitable for the arrangement of the limited space inside the suspension seat, and can meet the fatigue life requirements.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1 and Figure 2, the utility model includes an upper support frame 1 and a lower support frame 2, and the upper support frame 1 and the lower support frame 2 are connected by a rotating bracket 3: the upper and lower front parts of the rotating bracket 3 The moving shafts 4 and 5 are fixed, the two inner sides of the upper and lower support frames are provided with chute 6 and 7, the two moving shafts 4 and 5 are movably embedded in the chute, and the top of the upper moving shaft 4 is fixed with a rubber block 8; The upper and lower rear parts of the rotating bracket 3 are fixed with rotating shafts 9 and 10, and the upper and lower rotating shafts 9 and 10 are movable respectively in the shaft holes 11 and 12 of the upper support frame and the lower support frame. , The next two rotating shafts are covered with cylindrical rubber.

A preferred embodiment of the present utility model is: as shown in Figure 3, the rubber block 8 is fixed between the front splint 13 and the rear splint 14, the front splint 13 is fixed with connecting bolts 15, and the rear splint is fixed with a connecting bolt 15. Part 16, the connecting part is formed by connecting two semicircular connecting blocks and bolts. Described rotating shaft is covered with a cylinder rubber 17, is covered with a steel tube cover 18 on the cylindrical rubber 17, the front end of rotating shaft is provided with flat groove 19, and the center of rotating shaft has screw hole 20. Slide blocks 21 are fixed on both sides of the moving shaft, and rotating sleeves 22 are fixed on both sides of the rotating shaft.

When the seat encounters vibration and is pressed down by an external force, the rotating bracket 3 is opened downward, and the two moving shafts 4 and 5 slide forward in the chute, so that the rubber block 8 is pressed, and the rubber block 8 has just assumed the load. The effect of the spring slows down the pressure and achieves the effect of shock absorption; when the rotating bracket 3 is opened downward, the two rotating shafts behind the rotating bracket 3 can be pushed back against the support frame 1 and the lower support frame 2. Rotation, but because the front end of the rotating shaft is provided with a flat groove 19, and the flat groove 19 is fixed on the rotating bracket 3, thereby generating resistance, the cylindrical rubber sleeved on the rotating shaft acts as a spring, resulting in a highly non-linear Resistance to slow down the pressure and achieve the effect of shock absorption.
