Abstract
The utility model relates to a trigger switch formula car seat occupy -place pressure sensor belongs to automobile parts. Lower casing and pressure -bearing steel sheet fixed connection, there is the crotch that is used for connecting seat seat support spring at pressure -bearing steel sheet both ends, installation plastics fastener in the crotch on the pressure -bearing steel sheet, pressure trigger switch and base casing top fixed connection, two terminals of this pressure trigger switch are drawn forth through the preformed hole on the base casing, base casing and pressure lid joint, and compression spring is located between this base casing and the pressure lid, trigger the button apical grafting on arch and the pressure trigger switch with the integrative pressure of pressure lid. The advantage is novel structure, the installation of total need not to carry out any modification to the seat, in the time of between the marshall springs having stopped present seat support the pads sponge of installation in the past and supported the sponge, need solve the sensor and receive the figurative restricted problem of seat seatpad sponge and the seat marshall springs defect of making amendment, 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 auto parts and components, 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 trigger switch 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: 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, pressure activated switch is fixedly connected with above base housing, two binding posts of this pressure activated switch are drawn by the preformed hole on base housing, base housing and pressure cover clamping and pressure spring are between this base housing and pressure cover, protruding with the button apical grafting on pressure activated switch with the pressure activated of pressure cover one.
Described pressure activated construction of switch is: button, upper contact, lower contact, stage clip are positioned at housing, and lower contact is connected with binding post, and button is connected with upper contact, and stage clip is between upper contact and lower contact.
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
Lower house 2 is fixedly connected with pressure-bearing steel plate 3, there is the crotch 301 for connecting chair marshall springs 7 at pressure-bearing steel plate 3 two ends, in crotch 301 on pressure-bearing steel plate 3, plastic fastener 6 is installed, ensure that whole device is not shifted, when also avoiding vehicle operating, pressure-bearing steel plate 3 produces with seat marshall springs 7 noiselessness simultaneously, pressure activated switch 5 is fixedly connected with above base housing 2, two binding posts 505 of this pressure activated switch 5 are drawn by the preformed hole on base housing 2, signal for trigger switch 5 exports, be connected with body harness, base housing 2 and pressure cover 1 clamping, and pressure spring 4 is between this base housing 2 and pressure cover 1, with pressure activated protruding 101 and button 501 apical grafting on pressure activated switch 5 of pressure cover 1 one, pressure spring 4 compressive force determines pressure sensitivity.
Described pressure activated switch 5 structure is: button 501, upper contact 502, lower contact 503, stage clip 504 are positioned at housing 506, lower contact 503 is connected with binding post 505, button 501 is connected with upper contact 502, and stage clip 504 is between upper contact 502 and lower contact 503.
This structure has just set forth basic structure and the principle of this trigger switch, and in actual applications, the switch that can complete the utility model function all can adopt.
Principle of work: the utility model is arranged between seat cushion sponge 8 and seat marshall springs 7, when seat cushion sponge 8 is applied in enough load, seat cushion sponge 8 produces deformation, pressure is transmitted on pressure cover 1 by seat cushion sponge 8, pressure spring 4 pressurized shrinks, pressure cover 1 drives pressure activated protruding 101 to decline, the button 501 simultaneously pressure passed on pressure activated switch 5, stage clip 504 pressurized shrinks and upper contact 502 and lower contact 503 is connected, and now binding post 505 exports seat by occupy-place signal.
When removing external load, pressure spring 4 restores to the original state, drive pressure cover 1 and pressure activated protruding 101 to rise to reset, and the stage clip 504 also reinstatement in trigger switch 5, upper contact 502 and lower contact 503 are disconnected, be now off state, export seat not by occupy-place signal.
When external load is lower than setting value, pressure spring 4 deformation does not make pressure cover 1 and pressure activated projection 101 drop to impel upper contact 502 and lower contact 503 conducting in trigger switch 5, now exports seat not by occupy-place signal.
