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 spring-piece type 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: upper shell and lower house are by snap close clamping, device for being connected with body harness is fixedly connected with lower house, lower house 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, trigger circuit plate is had successively above this lower house, partition and conduction panel, and be all fixedly connected with the guide pillar on lower house by self poisoning guide hole, to contact with conduction panel with the shake-up block of upper shell one and connect, conduction panel body there is normal open point, rectangular opening through partition side is connected with trigger circuit plate all the time.
Described spacer structure is: partition body has a rectangular opening and a circular port.
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
Upper shell 1 and lower house 2 are by snap close clamping, device 8 for being connected with body harness is fixedly connected with lower house, lower house 2 is fixedly connected with pressure-bearing steel plate 3, there is the crotch 301 for connecting chair marshall springs 9 at pressure-bearing steel plate 3 two ends, in crotch 301 on pressure-bearing steel plate 3, plastic fastener 7 is installed, ensure that whole device is not shifted, when also avoiding vehicle operating, pressure-bearing steel plate 3 produces with seat marshall springs noiselessness simultaneously, trigger circuit plate 4 is had successively above this lower house, partition 5 and conduction panel 6, and be all fixedly connected with the guide pillar on lower house 2 by self poisoning guide hole, to contact with conduction panel 6 with the shake-up block 101 of upper shell 1 one and connect, the pressure sensitivity of the elastic deformation decision of conduction panel 6, conduction panel body 6 there is normal open point 601, rectangular opening 502 through partition 5 side is connected with trigger circuit plate 4 all the time, keep channel status, conduction panel is stainless steel, silver-plated on it, or other elastic metallic materials.
Described partition 5 structure is: partition body 501 has rectangular opening 502 and a circular port 503, it act as when there being load, and conduction panel 6 is connected with trigger circuit plate 4, in uncharged situation, for conduction panel 6 and trigger circuit plate 4 insulate.Its material can be elastic polymer material, as sponge, rubber etc., also can be the material such as felt, nonwoven fabrics.
Described trigger circuit plate 4 can be printed circuit board (PCB), copper material circuit or other be easy to conduct electricity the circuit card made by material, it there are circuit and resistance, by the various combination mode of the resistance value of resistance, the output signal of resulting pressure sensor is made to meet car load operating needs.
Principle of work: the utility model is arranged between seat cushion sponge 10 and seat marshall springs 9, when seat cushion sponge 10 is applied in enough load, seat cushion sponge 10 produces deformation, pressure is transmitted on upper shell 1 by seat cushion sponge 10, upper shell 1 drives to touch the while that block 101 declining and pressure is passed to conduction panel 6, conduction panel 6 produces downward deformation, and be connected by the trigger circuit plate 4 of partition 5 circular port position with partition 5 bottom, this timer 8 exports seat by occupy-place signal.
When removing external load, conduction panel 6 restores to the original state, and drives upper shell 1 and toucher block to rise, and be now open circuit or the state of value that transfinites, device 8 exports seat not by occupy-place signal.
When external load is lower than setting value, conduction panel 6 deformation is not enough to make self by the circular port of partition 5 and trigger circuit 4 conducting, and this timer 8 exports seat not by occupy-place signal.
