The specific embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1, it is a kind of embodiment scheme drawing of the utility model weight induction formula automotive seat.These weight induction formula automotive seat comprise seat main body 11, seat cushion 12 and weight induction device 13, weight induction device 13 is arranged in the seat cushion 12, for example, it can be installed between the seat cushion (INSERT) and seat cushion face cover of foaming, and with the seat line of centers symmetrically.Weight induction device 13 is used for responding to the passenger weight on the seat cushion 12, and it can tell the passenger clearly is adult or child, thereby the safety system of automobile just can be selected suitable safety measure according to induction information.
Introduce the concrete principle of work of weight induction device 13 below.See also Fig. 2, it is first kind of embodiment scheme drawing of the utility model weight induction device.This weight induction device comprises two sensing resistor R1 and R2, outer meeting resistance R3 and two sense switch S1 and S2.Be arranged on after sensing resistor R1, sensing resistor R2 and outer meeting resistance R3 are connected in series one by one between input end 21 and the mouth 22, sense switch S1 is parallel on the sensing resistor R1, and sense switch S2 is parallel on the sensing resistor R2.Sense switch S1 and S2 can be according to the weight sizes on the seat cushion 12 and conducting of adjustment own and open circuited state, and the conducting of sense switch S1 and sense switch S2 needs different weight numerical value, thereby realize the induction to Different Weight interval on the seat cushion 12.Such as, when not having the passenger on the seat cushion 12, sense switch S1 and S2 all are in off-state, and at this moment the resistance between input end 21 and the mouth 22 is R1+R2+R3; When sitting a child on the seat cushion 12, its weight can make sense switch S1 conducting, but still deficiency is so that also conducting of sense switch S2, sensed switch S 1 short circuit of sensing resistor R1 at this moment, thereby the resistance between input end 21 and the mouth 22 is R2+R3; When sitting an adult on the seat cushion 12, its weight can make sense switch S1 and the equal conducting of S2, two sensing resistor R1 and R2 sensed switch S 1 and S2 short circuit respectively at this moment, thereby the resistance between input end 21 and the mouth 22 is R3.So,, and then can make automobile safety system take corresponding safety measure as long as just can judge passenger's weight according to the resistance value between input end 21 and the mouth 22.
In actual applications, sense switch is to be set in the seat cushion 12, and it can cut-off state according to the load-bearing adjustment of itself, sees also Fig. 3, and it is a kind of example structure figure of the utility model sense switch.It comprises two-layer pellicle 31, two-layer conductive coating 32 and elastic insulated isolation layer 33.Two-layer conductive coating 32 is separately positioned on the partly middle of two-layer pellicle 31 inboards, and the position is corresponding.Elastic insulated isolation layer 33 is arranged on the boundary position between the two-layer pellicle 31, and the thickness of elastic insulated isolation layer 33 is greater than the thickness sum of two-layer conductive coating 32, and makes and form one between the two-layer conductive coating 32 by hole 34.When the weight of bearing when sense switch reached a particular value, the distortion of pellicle 31 can make up and down two-layer conductive coating 32 contacts and make switch conduction; When otherwise the weight of bearing when sense switch does not reach described particular value, can not contact between the two-layer conductive coating 32 and make switch disconnect.Therefore, sense switch has played the effect that utilizes load-bearing to control to cut-off.Wherein,, can regulate the described particular value of sense switch load-bearing, realize the demand of induction Different Weight by adjusting the thickness of elastic insulated isolation layer 33.Conductive coating 32 can be the printed coating that one deck contains silver powder and/or carbon dust, and it can directly spread upon pellicle 31 inboards.
It should be noted that, above-mentioned weight induction device 13 only is the more representational a kind of embodiment of the utility model, but do not limit the utility model, such as in weight induction device 13, a sensing resistor can only being set, and correspondingly dispose a sense switch with this; Also three or more sensing resistor can be set, and correspondingly dispose a plurality of sense switches, its structure can also be adjusted according to actual needs.As shown in Figure 4, it is second kind of embodiment scheme drawing of the utility model weight induction device.Compare with Fig. 2, the sensing resistor R1 of present embodiment simultaneously with a plurality of sense switch S11, S12 ..., the S1n parallel connection, sensing resistor R2 simultaneously with a plurality of sense switch S21, S22 ..., the S2n parallel connection.Wherein, sense switch S11, S12 ..., S1n all has identical load-bearing particular value, sense switch S21, S22 ..., S2n all has identical load-bearing particular value.Because the passenger is also non-homogeneous on the seat stressed, so adopt a plurality of sense switches in parallel here with sensing resistor, and each sense switch is distributed in the different position of seat cushion 12, therefore no matter what sitting posture the passenger is, as long as have a sense switch conducting just can judge passenger's weight, thereby present embodiment can improve the accuracy of weight induction.
See also Fig. 5, it is the third embodiment scheme drawing of the utility model weight induction device.Compare with Fig. 4, the sensing resistor R1 of present embodiment in parallel with series connected two groups of sense switch K1n, K2n (sense switch S11, S12 ..., S1n is parallel with one another, as first group of sense switch K1n; Sense switch S21, S22 ..., S2n is parallel with one another, as second group of sense switch K2n), sensing resistor R2 in parallel with series connected in addition two groups of sense switch K3n, K4n (sense switch S31, S32 ..., S3n is parallel with one another, as the 3rd group of sense switch K3n; Sense switch S41, S42 ..., S4n is parallel with one another, as the 4th group of sense switch K4n), wherein, sense switch S11, S12 ..., S1n and sense switch S21, S22 ..., S2n all has identical load-bearing particular value, sense switch S31, S32 ..., S3n and sense switch S41, S42 ..., S4n all has identical load-bearing particular value.Adopt two groups of series connected designs of sense switch can further discharge because of the unexpected closure of some sense switches or local pressure and judge by accident to people's situation is arranged, thereby present embodiment can further improve the accuracy of weight induction.
