The advantage is novel structure, solves the sensor and has received the figurative restricted problem of seat, and the increase of pressure detection area, life can improve, more is favorable to car seat occupy -place pressure sensor's generalization design.
Description
Technical field
The utility model belongs to a kind of automobile sensor, particularly automotive seat occupy-place pressure sensor.
Background technology
At present, so far, various functions is generally used widely domestic and international automotive technology development, the configuration that wherein automobile primary passive safety feature is necessary especially.In passive safety feature, safety strap and air bag are the two kinds of outfits receiving people's concern most.And the expansion of safety strap system system for prompting and air bag control required for Logic judgment just automotive seat occupy-place pressure sensor provide.Because the pressure sensor of automotive seat occupy-place is now mounted between seat surface sleeve and seat sponge more, this moulding just determining sensor must be subject to the restriction of seat surface moulding, and these moulding even can cause the limited of some functions of sensor.
Summary of the invention
The utility model provides a kind of pressure spring formula automotive seat occupy-place pressure sensor, with solve automotive seat occupy-place pressure sensor be arranged between seat surface sleeve and seat sponge time, make the moulding of sensor be subject to the restriction of seat surface moulding, even can cause the problem of some afunctions of sensor.
The technical scheme that the utility model is taked is: base is connected with pressure-bearing Interal fixation, there is the crotch for connecting chair marshall springs at pressure-bearing steel plate two ends, in crotch on pressure-bearing steel plate, plastic fastener is installed, active circuit plate is fixedly connected with base, this active circuit plate is connected with signal output part by the preformed hole on base, base is connected with pressure communication device by spring one, pressure communication device there is trigger point positioning groove, trigger point is embedded in the positioning groove of trigger point, both by self anticreep lock pin clamping, there is spring two trigger point and positioning groove inside, trigger point.
The utility model has the advantages that novel structure, because lower house is fixed on pressure-bearing steel plate, then by the crotch on pressure-bearing steel plate, whole device is fixed on seat marshall springs, crotch on pressure-bearing steel plate and install plastic fastener between seat marshall springs, ensure that whole device is not shifted, when also avoiding vehicle operating, pressure-bearing steel plate and seat marshall springs noiselessness produce simultaneously.The installation of total is without the need to carrying out any amendment to seat, when having stopped to be arranged between seat cushion sponge and the marshall springs supporting sponge in the past, need to modify defect to seat cushion sponge and seat marshall springs, solve the restricted problem of sensor by seat moulding, and pressure detection area increases, service life is improved, and is more conducive to the General design of automotive seat occupy-place pressure sensor.

Detailed description of the invention
Base 2 is fixedly connected with pressure-bearing steel plate 3, there is the crotch 301 for connecting chair marshall springs 12 at pressure-bearing steel plate 3 two ends, in crotch 301 on pressure-bearing steel plate 3, plastic fastener 9 is installed, ensure that whole device is not shifted, when also avoiding vehicle operating, pressure-bearing steel plate 3 produces with seat marshall springs 12 noiselessness simultaneously, active circuit plate 4 is fixedly connected with base 2, this active circuit plate 4 is connected with signal output part 10 by the preformed hole on base 2, base 2 is connected with pressure communication device 1 by spring 1, pressure communication device 1 there is trigger point positioning groove 6, trigger point 5 is embedded in trigger point positioning groove 6, both are by self anticreep lock pin clamping, prevent from coming off in trigger point positioning groove 6, there is spring 28 trigger point 5 and trigger point positioning groove 6 inside.Trigger point 5 and active circuit 4 conducting that spring 1 prevents from being connected with pressure communication device 1 in uncharged situation, produce false positive signal, the compressive force of spring 1 determines pressure sensitivity, and when no-load or load are lower than setting value, trigger point 5 and active circuit 4 are off state.
Its effect of spring 28 is when being subject to the load from top, trigger point 5 and active circuit 4 conducting, and spring 8 is squeezed and produces outbreak firmly, ensures that trigger point 5 and active circuit 4 have enough contact forces, makes stable output signal.
The material of active circuit plate 4 be copper material circuit or other be easy to the material of conducting electricity, comprise printed circuit board (PCB) etc.
Principle of work: the utility model is arranged between seat cushion sponge 11 and marshall springs 12, when seat cushion sponge 11 is applied in enough load, seat cushion sponge 11 produces deformation, pressure is transmitted on pressure communication device 1 by seat cushion sponge 11, spring 1 is squeezed contraction, trigger point 5 declines and active circuit 4 conducting simultaneously, the built-in spring 28 of trigger point 5 also shrinks simultaneously, and produce antagonistic force, ensure the stability of trigger point 5 decline and active circuit 4 conducting, now signal output part 10 exports seat by occupy-place signal.
When removing external load, spring 1 restores to the original state, and drives pressure communication device 1 and trigger point 5 to rise, and be now open circuit or the state of value that transfinites, signal output part 10 exports seat not by occupy-place signal.
When external load is lower than setting value, the compression set of spring 1 is not enough to trigger point 5 is declined and active circuit 4 conducting, and now signal output part 10 exports seat not by occupy-place signal.
