Device for protecting pedestrians in vehicle

Abstract

The invention provides a device for protecting pedestrians in a vehicle, belonging to the technical field of automobile spare parts and solving the problems that the traditional automobile hurts the pedestrians and a sensor has unreasonable arrangement and has a sense blind area. The device for protecting the pedestrians in the vehicle comprises a safety airbag, a gas generator, a sensor and a central processor, wherein the safety airbag is connected with the gas generator; both the gas generator and the sensor are connected with the central processor; the sensor is arranged at the front end of the vehicle and has a sense range corresponding to the width of the vehicle; the safety airbag is arranged in an engine hood; the safety airbag covers an area above a cross beam of a water tank outside the engine hood after unfolded and the shape of the safety airbag corresponds to the front part of the engine hood. The invention can effectively protect the pedestrians, and the safety airbag cannot influence the visual filed of drivers and has no sense blind area.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a vehicle protection device, in particular to a vehicle pedestrian protection device. Background technique [0002] Cars have become more and more popular as a means of transportation, but more and more car accidents have also caused many pedestrian casualties. In order to solve the damage caused by the collision of cars to pedestrians, people have carried out long-term exploration and proposed various solutions. [0003] For example, the Chinese patent literature discloses a car pedestrian protection airbag device [Application No.: 200820303290.7], which is installed on the engine compartment cover and includes a sensor, a central processing unit, a gas generator, an airbag and a radar detector. Installed in the front bumper of the car, the radar detector is installed above the windshield in the car, the target detection area of ​​the sensor is the front quarter area of ​​the ...

AI Technical Summary

Problems solved by technology

[0004] Although the above scheme has achieved protection to pedestrians to a certain extent, there are still deficiencies: 1. Due to the unreasonable selection of the position of the airbag, it cannot cover the area with high human injury value, and when the airbag is inflated, it will affect The driver's field of vision, resulting in the driver's inability to reasonably control the vehicle after the collision, increasing safety hazards

2. The setting of the sensor is not reasonable enough, and there is a sensing blind area
