Automobile seat cam adjusting type damping device and damping method and height adjusting method thereof

Abstract

The invention relates to an automobile seat cam adjusting type damping device and a damping method and a height adjusting method thereof, and aims at solving the problems that in the prior art, an automobile seat damping device is complex in structure, and the height cannot be adjusted. According to the technical scheme, the automobile seat cam adjusting type damping device comprises an upper frame, a lower frame, an outer shear shank, an inner shear shank, an air bag, a damper and a control mechanism. The outer shear shank is rotatably connected with the inner shear shank, and two ends of theouter shear shank are respectively connected with the upper frame and the lower frame; two ends of the inner shear shank are respectively connected with the upper frame and the lower frame; the air bag is connected with the lower frame and the inner shear shank; the damper is connected with the outer shear shank and the inner shear shank; the control mechanism comprises a valve body, a pressing tongue, a cam, an inhaul cable, a spring and a pressing tongue shaft. The valve body and the pressing tongue shaft are both fixed on the inner shear shank; and the pressing tongue is rotationally connected to the pressing tongue shaft. The damping device is good in damping effect, and the height can be adjusted.

Description

technical field [0001] The invention relates to a cam-adjustable shock-absorbing device for an automobile seat, a shock-absorbing method, and a height adjustment method, which are mainly used for shock absorption and height adjustment of driving seats in commercial vehicles and trucks. Background technique [0002] The car seat is an important part of the car that is directly related to the driver and passengers. The comfort of the car seat is a key factor in the design process of the car seat. Existing car seats are generally equipped with damping devices to alleviate the discomfort that the car brings to the driver and passengers due to bumps and vibrations during driving. Existing car seat damping devices generally include upper and lower frames and a shock absorbing structure arranged between the upper and lower frames. For example, a Chinese patent with a publication date of 20150624 and a publication number of CN204415199U discloses a car seat The shock-absorbing dev...

AI Technical Summary

Problems solved by technology

Existing car seat damping devices generally include upper and lower frames and a shock absorbing structure arranged between the upper and lower frames. For example, a Chinese patent with a publication date of 20150624 and a publication number of CN204415199U discloses a car seat The shock absorbing device, the structure of this invention is relatively complicated, relying on shock absorbing springs for shock absorption, the effect of cushioning and energy absorption is general

[0003] In addition, the existing damping devices for automobile seats also have the following disadvantages: 1. The cam and valve in the damping device are easy to disengage, resulting in failure of adjustment; 2. The existing damping devices generally do not have height adjustment. Function, single working height, unable to meet highly individual needs, and poor comfort; 3. A few shock absorbers with height adjustment function have complex structures and high costs, and the installed valve bodies are all specially made; 4. Some shock absorbers have The airbag is artificially inflated and deflated directly through the switch, the amount of inflated and deflated is not easy to control, and the use effect is poor
