Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As Figure 1-Figure 2, a kind of elastic cushion safety belt reminding device, for perceiving depositing for occupant on automotive seat
Include elastic cushion safety belt reminding sensor 2, seat foam pad 3, chair pelvis or suspension 4 and electronics in, the alarm set
Controller 14, the elastic cushion safety belt reminding sensor 2 setting seat foam pad 3 and chair pelvis or suspension 4 it
Between, the seat foam pads 3 bottom surfaces equipped with the groove 5 for installing elastic cushion safety belt reminding sensor 2, the electricity
Sub-controller 14 is connect by one or more conducting wires 13 with elastic cushion safety belt reminding sensor 2.Electronic control unit 14
The state of monitoring elasticity cushion safety belt reminding sensor 2, to determine whether seat is occupied.When passenger riding is in seat
On, the pressure that occupant weight generates is transmitted to by seat foam pad 3 on elastic cushion safety belt reminding sensor 2, to feel
Know the presence of occupant on seat.On the seat if there is passenger riding, it and does not fasten the safety belt, electronic control unit 14 will
Trigger sound or safety belt reminding indicator light.
As shown in Fig. 2, elastic cushion safety belt reminding sensor 2 includes the upper cover 6 from top to bottom set gradually, cushion
7, switching mechanism 8, bottom cover 9 and felt mattress 10 are correspondingly provided on the upper cover 6, cushion 7, bottom cover 9 and felt mattress 10 multiple
Location hole 12, upper cover 6, cushion 7, bottom cover 9 and felt mattress 10 are connected and fixed by multiple positioning pins 11 across location hole 12, institute
The switching mechanism 8 stated can either other fixed forms and pass through in upper cover 6 or bottom cover 9 by glue, mechanical system
Conducting wire 13 is connect with electronic controller, and the upper cover 6 is Nian Jie with seat foam pad 3, as shown in figure 3, in the present embodiment, upper cover
Upper surface 6a is equipped with double faced adhesive tape 15, and upper cover 6 is Nian Jie with seat foam pad 3 by double faced adhesive tape 15, to fixed elastic cushion peace
Full band reminder sensor 2 is on seat foam pad 3.
Upper cover 6 and bottom cover 15 are preferably made by on-deformable hard plastics, in this way, the pressure that occupant generates can
To be uniformly applied on cushion 7.Resilient rubbber cushion can be used in cushion 7.
As shown in fig. 4-5,7 middle part of cushion is equipped with the opening 16 for accommodating switching mechanism 8.The cushion 7
It is equipped with array distribution, multiple raised 7a, 7b towards at least one direction extension in upper cover 6 or bottom cover 9.The present embodiment
In, raised 7a, 7b are the cone-shaped bulge of inner hollow, and 7a and 7b be alternately arranged, and raised 7a is contacted with upper cover 6, raised 7b and
Bottom cover 9 contacts, and upper cover 6 and bottom cover 9 are separated by a distance (such as：8 millimeters) accommodate switching mechanism 8, between upper cover 6 and bottom cover 9
Distance be more than switching mechanism 8 height.There is certain interval between switching mechanism 8 and upper cover 6, it should on seat at this moment
Empty, when drive and passengers weight is loaded on seat foam pad 3, the bulging deformation of cushion 7 is shunk, pressure-driven upper cover 6 with
Switching mechanism 8 contacts, trigger switch mechanism 8, to generate passenger riding signal.Equally, protrusion is fabricated to the bullet towards side
Property pad can also achieve the effect that above-mentioned the same, but ordinary priority selects the cushion of above-mentioned both sides bulge-structure.
The elastic stiffness of cushion 7 is variable, for different seat bubble pads 3 and different chair pelvis or suspension 4
Using the cushion (such as silica gel) without elastic stiffness, so the elastic cushion safety belt reminding sensor of the present invention can match
The validity of sensor can also be ensured on different seats by setting.
As Figure 6-Figure 7, pass through comprising a depressible protrusion towards upper cover, switching mechanism 8 on switching mechanism 8
Switch bracket 17 is fixed on upper cover 6 or bottom cover 9, and the switch bracket 17 is equipped with the guiding for fixing conducting wire 13
Slot, switch bracket 17 can also transmit pressure between upper cover and switching mechanism.The 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
Situation, the second state of cushion stress deformation compression are occupied by occupant.When seat occupant weight one designated value of arrival or more
When big value, 7 stress deformation of cushion compression, upper cover 6 is translated along positioning pin, presses switching mechanism 8,8 activity of trigger switch mechanism
To the second state.
In practical application, switching mechanism 18 can be piston structure switch, reed switch, rubber elastic sheet switch, metal elastic
Piece switch or electromagnetic switch etc..Such as：14 stress deformation of cushion is shunk, and upper cover 6 is by occupant's pressure transmission plunger switch
Mechanism, triggering safety belt reminding device sensor 9.When using elastic sheet switch, switching mechanism 18 is a metal clips, can be with
It is rest directly upon on circuit board, circuit board can be fixed on bottom cover 15 or switch bracket 24.
It should be noted that：Those skilled in the art can be above-mentioned not to the progress of safety belt reminding device sensor
The modification referred to.Therefore, the present invention is not limited to the embodiment of disclosed description, and protection scope of the present invention is by as described below
