Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As Figure 1-Figure 2, a kind of elasticity cushion safety belt reminding device, 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 surface is provided with the groove 5 for installing elasticity cushion safety belt reminding sensor 2, described electronic controller 14 is connected with elasticity cushion safety belt reminding sensor 2 by one or more wire 13.Electronic control unit 14 monitors the state of elasticity cushion safety belt reminding sensor 2, in order to determine that whether seat is occupied.When passenger riding on the seat, the pressure that occupant weight produces is delivered on elasticity cushion safety belt reminding sensor 2 by seat foam pad 3, thus the existence of occupant on perception seat.If have passenger riding on the seat, and do not fasten the safety belt, electronic control unit 14 will toggle sound or safety belt reminding indicator lamp.
As shown in Figure 2, elasticity cushion safety belt reminding sensor 2 comprises the upper cover 6 set 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 hole 12, upper cover 6, cushion 7, bottom 9 and felt mattress 10 are connected and fixed through knock hole 12 by multiple locating dowel pin 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 with seat foam pad 3 by double faced adhesive tape 15, thus fixing elasticity cushion safety belt reminding sensor 2 is on seat foam pad 3.
Upper cover 12 and bottom 15 are preferably made by on-deformable hard plastics, and like this, the pressure that occupant produces can be applied on cushion 7 uniformly.Cushion 7 can adopt resilient rubbber cushion.
As shown in fig. 4-5, the opening 16 for holding switching mechanism 8 is provided with in the middle part of cushion 7.Described cushion 7 is provided with array distribution, multiple protruding 7a, 7b of extending towards at least one direction in upper cover 6 or bottom 9.In the present embodiment, protruding 7a, 7b are the cone-shaped bulge of inner hollow, 7a and 7b alternately arranges, protruding 7a contacts with upper cover 6, protruding 7b contacts with bottom 9, upper cover 6 and bottom 9 are separated by a distance (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.Having certain interval between switching mechanism 8 and upper cover 6, seat at this moment should be empty, when 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 produces passenger riding signal.Equally, projection is made into and also can reaches above-mentioned the same effect towards the cushion of side, but ordinary priority selects the cushion of above-mentioned both sides bulge-structure.
The elastic stiffness of cushion 7 is variable, the cushion (as silica gel etc.) without elastic stiffness is adopted, so elasticity cushion safety belt reminding sensor of the present invention can be configured in the validity that different seats can also ensure sensor for different seats bubble pad 3 and different chair pelvis or suspension 4.
As Figure 6-Figure 7, switching mechanism 8 comprises 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 between upper cover and switching mechanism transmission of pressure.Described guide groove can be to toothing or S shape loop structure.Switching mechanism has instruction seat no-load condition, the first state of the non-stress deformation of cushion and instruction seat and is taken the second state of situation, the compression of cushion stress deformation by occupant.When seat occupant weight arrives a designated value or greater value, cushion 7 stress deformation compress, upper cover 6 along locating dowel pin translation, PS (Push Switch) mechanism 8, trigger switch mechanism 8 activity to the second state.
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.Such as: cushion 14 stress deformation shrinks, occupant's pressure is transmitted plunger switching mechanism by upper cover 12, triggering secure band alarm set sensor 9.When adopting elastic sheet switch, switching mechanism 18 is metal spring sheets, can directly lay on circuit boards, and circuit card can be fixed on bottom 15 or switch bracket 24.
It is to be noted that those skilled in the art can carry out above-mentioned NM amendment to safety belt reminding device sensor.Therefore, the present invention is not limited to the embodiment of disclosed description, and protection scope of the present invention defined by claim as described below and equivalent scope thereof.
