[0020] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0021] like Figure 1 As shown, the automobile seat comprises a seat frame frame A and a backrest frame B, wherein the seat frame frame A is used to support the buttocks of the passenger, and the backrest frame B is installed on the seat frame frame A and is used to support the back of the passenger.

[0022] like Figure 2-Figure 3As shown, the seat frame frame A includes a first fixing plate A1, a second fixing plate A2 and a seat shock absorbing mechanism A3 according to a preferred embodiment of the utility model, wherein the seat shock absorbing mechanism A3 extends through the first fixing plate A1 and the second fixing plate A2 to provide a vibration suppression function, minimize the shaking of the second fixing plate A2, and thus improve the comfort of the car seat. In this embodiment, the first fixing plate A1 is a bracket mounted on a long slide rail, and the second fixing plate A2 is a side frame mounted on the bracket. When encountering a bumpy road, the vibration feedback brought to the side frame is weakened by means of the seat shock absorbing mechanism A3, thereby preventing passengers from getting dizzy.

[0023] like Figure 4-Figure 5 As shown, the seat shock absorbing mechanism A3 includes a step bolt 1, a locking nut 2, a metal flat washer 3, a metal bushing 4 and a buffer pad 5, wherein the step bolt 1 passes through the through holes of the first and second fixing plates A1 and A2 and is locked by the locking nut 2, the metal flat washer 3 abuts between the step surface 11 of the step bolt 1 and the locking nut 2 to provide axial limiting and support, the metal bushing 4 is fixed (for example, welded) on the first fixing plate A1, and the buffer pad 5 is arranged between the step bolt 1 and the metal bushing 4 to absorb vibration. In this way, when the locking nut 2 is locked into the step bolt 1 with a fixed torque, the buffer pad 5 is compressed, and plays the role of energy absorption and shock absorption while providing support.

[0024] In this embodiment, the buffer pad 5 includes a T-shaped rubber pad 51 and a rubber flat pad 52, wherein the vertical section of the T-shaped rubber pad 51 is arranged between the relative surfaces of the step bolt 1 and the metal bushing 4 to reduce radial vibration, the horizontal section of the T-shaped rubber pad 51 is arranged between the relative surfaces of the metal bushing 4 and the second fixing plate A2 to reduce axial vibration, and the rubber flat pad 52 is arranged between the relative surfaces of the metal bushing 4 and the metal flat pad 3 to reduce axial vibration. It should be understood that the arrangement of the metal bushing 4 can avoid fatigue damage to the buffer pad 5 caused by the sharp edge of the first fixing plate A1, and the length of the metal bushing 4 directly defines the axial compression amount of the T-shaped rubber pad 51 and the rubber flat pad 52.

[0025] In another embodiment, Figure 6 As shown, the buffer pad 50 is an integrated rubber pad, which is in an I-shape as a whole.

[0026] In a preferred embodiment, the material of the buffer pads 5, 50 can be ethylene propylene diene monomer rubber (EPDM), nitrile butadiene rubber (NBR), natural rubber (NR), polyurethane rubber or acrylic rubber (ACM), with a Shore hardness of 35 to 80 and a compression amount of 15% to 30%. It should be understood that in the split embodiment, the materials of the T-shaped rubber pad 51 and the rubber flat pad 52 of the buffer pad 5 can be selected to be the same or different as needed, so that the hardness of the two rubber pads can be changed separately according to the load conditions of the use scenario to achieve a better shock absorption effect. Moreover, the split buffer pad 5 is not only convenient for installation, but the gap between the T-shaped rubber pad 51 and the rubber flat pad 52 allows the rubber pad caused by radial and / or axial shaking here to be squeezed and deformed into the gap, thereby providing a better shock absorption effect.

[0027] The above is only a preferred embodiment of the utility model, and is not intended to limit the scope of the utility model. The above embodiments of the utility model can also be modified in various ways. That is, all simple, equivalent changes and modifications made according to the claims and the contents of the specification of the utility model application fall within the scope of protection of the claims of the utility model patent. The conventional technical contents are not described in detail in the utility model.
