Auxiliary driving side instrument platform surface object detection alarm device

Abstract

The invention provides an auxiliary driving side instrument platform surface object detection alarm device, which belongs to the technical field of automobiles. The problems of complex installation, not comprehensive detection, missing detection and false alarm in the prior art are solved. The detection alarm device comprises an alarm unit. The detection alarm device further comprises a capacitive sensor used for detecting whether an object is placed on an auxiliary driving side instrument platform, and a driving module used for driving the alarm unit to work. The capacitive sensor is connected with the alarm unit through the driving module. The capacitive sensor comprises an upper polar plate, a lower polar plate and an elastic framework. The lower polar plate is arranged on the surface of the instrument platform. The upper polar plate is adhered to the elastic framework and is correspondingly arranged right above the lower polar plate. An insulating dielectric is arranged between the upper polar plate and the lower polar plate. The device is simple in structure and convenient to install, and can be used for detecting an object on the surface of the auxiliary driving side instrument platform more accurately.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a device for detecting and alarming objects on the surface of an instrument panel on the passenger side. Background technique [0002] In the process of a frontal high-speed collision of the car, the frontal airbag on the passenger side will detonate, and after inflated and deployed, it will play a role in cushioning and protecting the passenger on the passenger side. However, if an object is temporarily placed on the surface of the instrument panel on the passenger side, that is, above the front airbag module of the passenger's front when an accident occurs, the object may have a certain quality, hardness or even a sharp shape, and it may be caused by the occupant. The rapid detonation of the airbag will cause it to attack any occupant in the car, and even cause casualties. Therefore need a kind of device that can make the occupant in the car notice in time the article on the...

Problems solved by technology

But at the same time, the device uses a photoelectric sensor to check the items on the instrument panel, which is not only expensive and complicated to install, but also the detection is not comprehensive enough. Only when an item of a certain size just blocks the reception of the photoelectric sensor can the detection behavior be realized, and there is a certain possibility of missing detection. Risk, it may also be that the items above are not placed on the instrument panel to block the photoelectric sensor and cause false alarms
