Abstract
The utility model discloses a pressure type car rainfall sensing device, including pressure -sensitive device, protector and base, pressure -sensitive device links up with the response vibrating diaphragm including response vibrating diaphragm and pressure sensor, pressure sensor installation face, and pressure sensor comes analysis rainfall size through the response rain drops to the impact of response vibrating diaphragm, and the response vibrating diaphragm is provided with protector all around, protector prevent wind the rail setting peripheral at the response vibrating diaphragm including preventing wind rail and wash port, and the wash port setting is preventing wind rail and response vibrating diaphragm linking department, response vibrating diaphragm setting to set up the semi -closed space on the base under the response vibrating diaphragm at base front end, pressure sensor. Compared with the prior art, the beneficial effects of the utility model are that: the more effective rain drops of sensing are to pressure sensor's impact, the influence of having avoided air convection, ponding to lead to the fact the sensor, and the fin combines with vehicle antenna, neither results in aesthetic problems, also prevents the influence that other factors led to the fact.
Description
Technical field
The utility model is related to rainfall sensing device field, and in particular to a kind of pressure type automobile rainfall sensing device.
Background technology
The automobile rainy day to run over need in journey opens windscreen wiper, to prevent windshield from being obscured by rainwater contamination retracement line, protects
Card normal driving, therefore typically control to automatically control windscreen wiper using rainfall sensing device.In the prior art, automobile rainfall sensing
Device has two kinds, and one kind is photo-electric, and front windshield in-car side is placed in by transmitting tube and reception pipe, and infrared transmitting tube is to gear
Wind glass launches light, and when there are raindrop on glass, the light of reflection changes, and then judges the size of rainfall, another
It is condenser type to plant, and capacitive sensing piece is affixed on glass, when rain is assembled, the size of rainfall is sensed by sensing chip, this
Both of which needs to install equipment in the car, it is impossible to the directly impact of effective sensing raindrop, and then can not accurate discriminatory analysis rain
Amount size.
Utility model content
The purpose of utility model is to provide a kind of pressure type automobile rainfall sensing device, with solving above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of pressure type automobile rainfall sensing device,
It is characterised in that it includes pedestal and the pressure sensitive device on pedestal, pressure sensitive device is including induction vibration film and therewith
The pressure sensor of connection, pressure sensor analyzes rainfall size by sensing raindrop to the impact of induction vibration film；It is described
Induction vibration film periphery is additionally provided with windproof fence, and windproof fence is additionally provided with osculum with induction vibration film joining place.
Further, the pressure sensitive device is removably mounted on the pedestal.
Further, the induction vibration film has a certain degree with roof planar shaped, is inclined and mounted on pedestal.
Further, the empennage of car antenna is set in being additionally provided with the pedestal.
Compared with prior art, the beneficial effects of the utility model are：More effectively sense raindrop to pressure sensor
Impact, it is to avoid the influence that cross-ventilation, ponding are caused to sensor, rainfall sensing device is combined with car antenna, both
Do not affect the appearance, prevented also from the influence that other factors are caused.
