Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As Figure 1-Figure 2, a kind of elasticity cushion safety belt reminding device, for the existence of occupant on perception automotive seat, this alarm set comprises elasticity cushion safety belt reminding sensor 2, seat foam pad 3, chair pelvis or suspension 4 and electronic controller 14, described elasticity cushion safety belt reminding sensor 2 is arranged between seat foam pad 3 and chair pelvis or suspension 4, described seat foam pad 3 bottom surfaces are provided with the groove 5 for elasticity cushion safety belt reminding sensor 2 is installed, described electronic controller 14 is connected with elasticity cushion safety belt reminding sensor 2 by one or more wires 13.Whether electronic control unit 14 is monitored the state of elasticity cushion safety belt reminding sensor 2, occupied in order to determine seat.When passenger riding on the seat, occupant's body weight produce pressure be delivered on elasticity cushion safety belt reminding sensor 2 by seat foam pad 3, thereby occupant's existence on perception seat.If there is passenger riding on the seat, and do not fasten the safety belt, electronic control unit 14 will trigger sound or safety belt reminding indicator lamp.
As shown in Figure 2, elasticity cushion safety belt reminding sensor 2 comprises the upper cover 6 setting gradually from top to bottom, cushion 7, switching mechanism 8, bottom 9 and felt mattress 10, described upper cover 6, cushion 7, on bottom 9 and felt mattress 10, correspondence is provided with multiple knock holees 12, upper cover 6, cushion 7, bottom 9 and felt mattress 10 are connected and fixed through knock hole 12 by multiple locating dowel pins 11, described switching mechanism 8 can pass through glue, mechanical system or other fixed form are on upper cover 6 or bottom 9, and be connected with electronic controller by wire 13, described upper cover 6 is bonding with seat foam pad 3, as shown in Figure 3, in the present embodiment, upper cover upper surface 6a is provided with double faced adhesive tape 15, upper cover 6 is bonding by double faced adhesive tape 15 and seat foam pad 3, thereby fixing elasticity cushion safety belt reminding sensor 2 is on seat foam pad 3.
As shown in Fig. 4-Fig. 5, cushion 7 middle parts are provided with the opening 16 for holding switching mechanism 8.Described cushion 7 is provided with at least one direction is extended in upper cover 6 or bottom 9 protruding 7a, 7b array distribution, multiple.In the present embodiment, the cone-shaped bulge that projection 7a, 7b are inner hollow, 7a and 7b alternately arrange, projection 7a contacts with upper cover 6, projection 7b contacts with bottom 9, upper cover 6 and bottom 9 are separated by a distance to (as: 8 millimeters) and hold switching mechanism 8, the distance between upper cover 6 and bottom 9 is greater than the height of switching mechanism 8.Between switching mechanism 8 and upper cover 6, having certain interval, should be empty on seat at this moment, in the time that drive and passengers weight is loaded on seat foam pad 3, the bulging deformation of cushion 7 shrinks, pressure-driven upper cover 6 contacts with switching mechanism 8, trigger switch mechanism 8, thus produce passenger riding signal.Equally, projection is made into towards the cushion of a side also can reach above-mentioned the same effect, but ordinary priority is selected the cushion of above-mentioned both sides bulge-structure.
The elastic stiffness of cushion 7 is variable, elasticity cushion safety belt reminding sensor of the present utility model adopts cushion without elastic stiffness (as silica gel etc.) for different seat bubble pad 3 and different chair pelvis or suspension 4, so can be configured in the validity that can also ensure sensor on different seats.
As Figure 6-Figure 7, on switching mechanism 8, comprise a depressible projection towards upper cover, switching mechanism 8 is fixed on upper cover 6 or bottom 9 by switch bracket 17, described switch bracket 17 is provided with the guide groove for fixing cord 13, switch bracket 17 also can be between upper cover and switching mechanism transmission of pressure.Described guide groove can be to toothing or S shape loop structure.Switching mechanism has the unloaded situation of instruction seat, cushion, and the first state of stress deformation and instruction seat are not taken the second state of situation, the compression of cushion stress deformation by occupant.In the time that seat occupant weight arrives a designated value or larger value, cushion 7 stress deformations compress, and upper cover 6 is along locating dowel pin translation, PS (Push Switch) mechanism 8, trigger switch mechanism 8 activity to the second states.
In practical application, switching mechanism 18 can be piston structure switch, reed switch, rubber elastic sheet switch, metal spring sheet switch or electromagnetic switch etc.For example: cushion 14 stress deformations shrink, and occupant's pressure is transmitted plunger switching mechanism by upper cover 12, trigger safety belt reminding device sensor 9.In the time adopting elastic sheet switch, switching mechanism 18 is metal spring sheets, can directly be placed on circuit card, and circuit card can be fixed on bottom 15 or switch bracket 24.
It should be noted that: those skilled in the art can carry out above-mentioned NM amendment to safety belt reminding device sensor.Therefore, the utility model is not limited to the embodiment of disclosed description, and protection domain of the present utility model is defined by claim as described below and equivalent scope thereof.
