Abstract
The utility model discloses a sensor which can send out a trigger signal towards a gas generator when the automobile collision occurs. The sensor is a metal seat body whose lower part is a flat bottom plate and upper part forms an inversed bowl shape, and the metal seat body is provided with a small insulating ball, a movable metal ball pressing post, a spring, a spring adjustment sleeve and an insulation sleeve. The sensor for the safety air bag of the automobile has the advantages of simple structure, easy fabrication, convenient operation, reliable performance and low cost, and is convenient to popularize and use on various existing automobiles.
Description
The utility model relates to a kind of when taking place to collide, and can send the sensor of energizing signal to safe automobile air bag.
Nowadays on most automobiles abroad, safety air bag is installed all on the car especially, prevents that driver and crew and bearing circle, instrument carrier panel etc. from sharp impacts taking place and injured.This safety air bag generally all is partly to be made of sensor, gas generator and air bag three.The deceleration/decel of sensor root a tree name vehicle is judged the degree of vehicle collision.When vehicle was subjected to positive sharp impacts because of having an accident, the sensor-triggered gas generator made it produce a large amount of gases in the short time at the utmost point and charges into air bag, allows air bag expand rapidly, kept off before navigating mate, thereby played cushioning and protection.Present external employed sensor, as " automobile journal " 96 years 4～6 interim introduce, it comprises housing, pull back spring, backing block, eccentric weight and eccentric rotor, and be installed in parts such as armature contact on the eccentric rotor and fixed contact.Under the normal circumstances, eccentric weight and eccentric rotor lean on backing block under the pull back spring effect, and armature contact does not contact with fixed contact.When automobile was subjected to impulsive force and impulsive force and surpasses predetermined value, the eccentric rotor rotation made the armature contact that is installed on the eccentric rotor engage with fixed contact, sends energizing signal.This sensor parts are more, and structure is very complicated, and manufacture difficulty is big, and cost is high again, can't popularize at home at all.This sensor is when experiencing collision alarm simultaneously, because the path of motion of armature contact is a camber line, its stroke is longer, so the time that energizing signal produces is longer, about 20ms, safety is descended to some extent.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of simple in structure, and is easy to manufacture, easy to use, good reliability, and cost is low, is convenient to the safe automobile air bag sensor of penetration and promotion.
The purpose of this utility model is to reach by following measure: it is made up of metal pedestal, insulation bead, live metal pressure ball post, spring, spring adjustment set and insulation sleeve.Wherein the bottom of metal pedestal is a flat underside, and top is the bowl-shape shape of left-hand thread.The insulation bead places in the pit of flat underside central authorities in the metal pedestal.Be positioned at the live metal pressure ball post of spring adjustment set, push down by the spring bead that will insulate.Spring adjustment set is arranged in the endoporus of insulation sleeve, and insulation sleeve is fixed on the center of top of metal pedestal again.
Accompanying drawing is a constructional drawing of the present utility model.
The utility model is described in further detail below in conjunction with embodiment: this safe automobile air bag sensor is to be flat underside by a bottom, and top is metal pedestal (1), insulation bead (2), live metal pressure ball post (3), spring (4), spring adjustment set (5) and insulation sleeve (6) formation of the bowl-shape shape of left-hand thread.Wherein insulation bead (2) is put into the pit of metal pedestal (1) flat underside central authorities.By screw thread insulation sleeve (6) is fixed on the central authorities of pre-portion of metal pedestal (1) simultaneously.Allow spring adjustment set (5) by in the endoporus that is threaded in insulation sleeve (6), the top of live metal pressure ball post (3) is enclosed within the spring adjustment set (5).And between live metal pressure ball post (3) and spring adjustment set (5), lay compression spring (4).Bead (2) is pushed down and will insulate in the lower end of live metal pressure ball post (3).In the central pit of metal pedestal (1) bottom, also be drilled with a pressure test aperture (7).It can allow ergographic measuring staff therefrom insert, and comes the adjustment pressure of test spring (4).Have an end of an electrode to join with spring adjustment set (5) in addition, the other end of electrode joins with metal pedestal (1).
When this safe automobile air bag sensor uses, be to allow it be fixed on the automobile, move with car.Under the cruising situation, the spring on this sensor makes live metal pressure ball post push down the insulation bead tightly, allows live metal pressure ball post not contact with the bottom surface of metal pedestal, does not also just have energizing signal to send to gas generator.When in a single day automobile has an accident when being subjected to from either party sharp impacts of front, rear, left and right, because action of inertia, the insulation bead will fly out between the pit of live metal pressure ball post and base plate central authorities.The live metal pressure ball is under the effect of spring like this, and the base plate with the metal pedestal contacts post, so electrode is connected rapidly; send energizing signal to gas generator; make it produce a large amount of gases fast and charge into air bag, allow the airbag inflation retaining before driver and crew, thereby shield.
The utility model has following advantage compared to existing technology: this safe automobile air bag Sensor construction is simple, it is easy, easy to use to make, reliable operation, be quick on the draw, give birth to The product cost is low, is convenient to promote the use of at existing various automobile.
Claims (1)
1, a kind of safe automobile air bag sensor that can come to send energizing signal according to the deceleration/decel of vehicle to gas generator, it is characterized in that: it comprises metal pedestal (1), insulation bead (2), live metal pressure ball post (3), spring (4), spring adjustment set (5) and insulation sleeve (6), wherein the bottom of metal pedestal (1) is a flat underside, and top is the bowl-shape shape of left-hand thread; Insulation bead (2) places in the pit of flat underside central authorities in the metal pedestal; The lower end that is positioned at the live metal pressure ball post (3) of spring adjustment set (5) bead (2) that will insulate is pushed down; Spring adjustment set (5) is arranged in the endoporus of insulation sleeve (6); Insulation sleeve (6) is the center of top that is fixed on metal pedestal (1).
