A high-efficiency automotive airbag shock absorber

Abstract

The invention discloses an efficient vehicle airbag shock absorber which comprises a shock absorber assembly. The shock absorber assembly comprises an oil storage barrel, a working cylinder, a connection rod, a guider, an oil seal, a piston valve assembly and a bottom valve assembly, wherein the guider and the bottom valve assembly are arranged at the two ends in the oil storage barrel; the oil storage barrel is sleeved with a rigid spring. An air intake device comprises an air intake nozzle, a concave washer, a spring and an end cover, wherein an air inlet in the lower end of the air intake nozzle is sleeved with the spring in a connected mode; the concave washer and the end cover are fixed through a bolt set. The bolt set is connected with the end cover and a fixing device with matched dimensions. The built-in airbag shock absorber has a much better shock absorption effect compared with a traditional hydraulic shock absorber, and oil leakage is avoided; besides, the mounting difficulty of an airbag is reduced. The whole shock absorber is ingenious in design, clear in structure and convenient to mount and debug, and the service life of the absorber is prolonged quite efficiently, so that the shock absorber has higher market competitiveness compared with the traditional hydraulic shock absorber.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorption, in particular to a high-efficiency automobile airbag shock absorber. Background technique [0002] The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. The existing shock absorber includes a working cylinder. A connecting rod is arranged in the working cylinder and protrudes from one end of the working cylinder. A guide is arranged on the port where the connecting rod extends out of the working cylinder. The traditional guide is connected to the connecting rod. The position is exposed relative to the outside world, and after long-term use, it will cause damage to the funct...

AI Technical Summary

Problems solved by technology

The existing shock absorber includes a working cylinder. A connecting rod is arranged in the working cylinder and protrudes from one end of the working cylinder. A guide is arranged on the port where the connecting rod extends out of the working cylinder. The traditional guide is connected to the connecting rod. The part is in a bare state relative to the outside world. After a long time of use, it will cause damage to the function of the guide and a part of the connecting rod, reducing the service life of the shock absorber.

When the car is running, due to the unevenness of the road surface, if there is no shock absorber for buffering, it will bring discomfort to the passengers and affect the service life of the car. The connecting rod of the shock absorber drives the piston head to compress rapidly During the process, a section of vacuum volume will be generated, which will cause damping phenomenon when the connecting rod rebounds, thus affecting the shock absorption effect. This section of vacuum is particularly prominent in high-speed driving cars, especially racing cars. The straight cylinder hydraulic shock absorber currently used The shock absorption effect is poor, and the quality is unstable, and oil leakage is easy to occur. The airbag structure of the traditional external airbag shock absorber is unreasonable, and the connection between the airbag and the shock absorber is adopted, which will cause installation difficulties and poor sealing performance. Difficult to guarantee, the existing technology such as the Chinese invention patent with the Chinese patent authorization announcement number CN201320052403 discloses a kind of integral airbag shock absorber, but this kind of shock absorber is inconvenient to install and debug, and cannot be very efficiently increased The service life of the shock absorber and the cost of vehicle maintenance are high. For this reason, we propose a high-efficiency automobile airbag shock absorber
