Technical field
The present invention relates to a kind of safe automobile air bag rigidity detection devices, belong to Automobile Parts Inspection technical field.
Background technology
Air bag is configured as the auxiliary of vehicle body passive safety, is increasingly valued by people.When automobile and barrier touch
After hitting, referred to as primary collision, occupant collides with interior component, referred to as secondary collision, air bag after primary collision, secondary touch
A gassiness air cushion is opened before hitting rapidly, " flutter on air cushion " to mitigate when occupant being made to move because of inertia occupant by
To impact and absorb collision energy, mitigate the extent of injury of occupant.
Safe automobile air bag equally also has its unsafe one side.According to calculating, if automobile is travelled with the speed per hour of 60km, suddenly
Shock vehicle can be enabled to stop within 0.2 second, and air bag can then be popped up with the speed of about 300km/h, and thus produced by
Impact force there are about 180 kilograms, and the impact force that the safe automobile air bag of different-stiffness generates human body has very big difference, therefore has
Necessity is detected the rigidity of safe automobile air bag to ensure air bag in safe range inner impact human body.
In front of air bag distribution in the car (positive co-driver), side (interior front-seat and heel row) and three sides of roof
To, and existing safe automobile air bag rigidity detection device can only generally detect the air bag of fixed position, it cannot be to interior institute
There is air bag all to carry out rigidity test.In addition, existing safe automobile air bag rigidity detection device the degree of automation is low, need to artificially grasp
Make, subjectivity is big, and human error is big and accuracy of detection is low, poor reliability.

Beneficial effects of the present invention：A kind of safe automobile air bag rigidity detection device provided by the invention, displacement sensor
Setting, the velocity of displacement of displacement and side stripper plate for detecting upper extrusion board；The setting of pressure sensor, for examining
Survey reaction force when upper extrusion board and side stripper plate extruding gasbag；The setting of pressure sensor on upper extrusion board, for examining
Air bag is surveyed to the reaction force of static plate, plays the role of reference；The setting of pressure sensor on the stripper plate of side, for detecting
Reaction force of the air bag to dynamic plate；The power of driving mechanism is adjustable, by adjusting the speed of driving mechanism, can get side and squeezes
The relation curve of the speed of plate and the reaction force suffered by it, and then obtain the rigidity of air bag；The setting of movable block makes to squeeze
Pressing plate upward and downward height is adjustable, and then makes different types of interior air bag that can be put into the turning of L-type operation console, therefore of the invention
It is versatile, it can be used for the detection of various air bags in automobile；Screw rod rotates in fixed block, drives movable block upper and lower displacement, into
One step drives upper extrusion board upper and lower displacement；The setting of square groove limits upper extrusion board and is rotated with the rotation of screw rod, therefore
Upper extrusion board can only with the rotation of screw rod and upward and downward move, realize upper extrusion board upper and lower displacement；Screw rod and movable block spiral shell
The setting of line connection, keeps the step-length of upper extrusion board upper and lower displacement small, can accurately adjust the upward and downward displacement of upper extrusion board, and just
In in the turning for firmly securing the air-bag to L-type operation console, therefore testing result of the present invention is true and reliable, and precision is high；Sliding rail, cunning
The setting of block and driving mechanism makes high degree of automation of the present invention, and side stripper plate speed is controllable, and human error is small, measurement structure
Accurately.
