Sliding type bumper and lifting arm, buffering device and SRS sensing facilities

Abstract

The invention relates to a sliding type bumper, a lifting arm , a cushioning device and an SRS sensing facility; the sliding type bumper is divided into an inner layer and an outer layer; the inner layer surrounds one circle of a vehicle body, namely, a full-surrounding type; the inner layer is an arc and only is arranged at the vehicle head part and the vehicle tail part to be arc; the inner layer is one circle and is only arranged at the vehicle head and the vehicle tail to be round; the inner layer is provided with an upper slideway slot and a lower slideway slot; the outer layer is a movable frame and can slide at the inner layer; the sliding type bumper is mounted on the lifting arm arranged on a large truck and can be reduced to the height which is proper with the height of a bumper of a small vehicle; the cushioning device of the sliding type bumper can absorb more impact energy and the slide type bumper that is almost contacted and impacted by arc incline completely can enlarge the inclination between two bumpers; impacted vehicles or substances are easily poked by the fast sliding outer layer, transferred and can laterally and safely slide. A direct contact connection type SRS sensing facility has the advantages of simple structure, low cost, being convenient to mount and dismount, being hard to be error and forming a cheap SRS system with the existing air sac module and safety belt tension device, so as to be popularized in the vehicles of middle and lower grades and oversize vehicles.

Description

[Affiliated technical field] [0001] The invention relates to a vehicle bumper and an SRS sensing system, in particular to a sliding bumper and a buffer device with an outer layer that can slide on the inner layer and can automatically brake and can be raised and lowered. The direct contact wiring type SRS sensing facility. [Background technique] [0002] Existing vehicle bumpers have poor vehicle protection performance, and only passively accept and absorb the direct impact force. The excessively high bumper of a large vehicle can easily cause small vehicles to be "disasterd". Generally, large vehicles do not have an SRS system, and tragedies of vehicle crashes often occur among large vehicles. [Content of the invention] [0003] In order to solve the problems of poor vehicle protection performance of existing bumpers, dislocation of bumpers of large and small vehicles, and high price of existing SRS systems, the present invention provides a sliding bumper, lifting arm, b...
