Description
Technical field
The utility model relates to the automobile driving safe apparatus field, particularly a kind of safety belt prompt device.
Background technology
In recent years, along with people's living standard improve constantly, increasing people buys private car as walking-replacing tool.Light car is put into effect and corresponding preferential policy for purchasing again in country, buys one new " bright spot " that private car has become people's consumption.Be accompanied by the relevant preferential policy of country appearance, on market, the low-medium-high level vehicle of different brands has also greatly satisfied different levels customer's consumption demand, people can select to be fit to the private car of oneself according to the ability to bear of oneself, thereby realize having the dream of private car.In recent years, private car newly-increased settled quantity larger amplification every year.Especially country in 2009 implements subsidy to buying power actuated vehicle, causes private car quantity to be increased sharply.
Along with automobile quantity increases gradually, the traffic accident frequency is also more and more frequent, main security facilities safety strap as automobile seems particularly important, a lot of people can forget when driving and fasten the safety belt, therefore the accident that causes owing to not fastening seat belts is too numerous to enumerate, is badly in need of a kind of safety belt prompt device for this reason and whether passengers inside the car are fastened the safety belt reminds.
The utility model content
for above problem, the utility model is by a kind of safety belt prompt device of design, can whether fasten the safety belt to passengers inside the car and remind, thereby can reduce the safety misadventure that produces because of safety belt buckling free, for reaching this purpose, the utility model provides a kind of safety belt prompt device, comprise micro controller system, infrared receiving device, upper AND circuit, pressure sensor, movable switch, lower AND circuit and aerotron, described infrared receiving device is connected with micro controller system P3.0 port by upper AND circuit, described pressure sensor is connected with the vacant port of micro controller system, described movable switch has two grades, described movable switch is connected with micro controller system P3.1 port by lower AND circuit, described transistor base is connected with micro controller system P0.3 port, described precaution device is connected with the other two-stage of aerotron.
As further improvement of the utility model, described precaution device comprises verbal cue device and loudspeaker, and this patent precaution device can use the verbal cue mode to carry out early warning.
As further improvement of the utility model, described safety belt prompt device also comprises signal lamp, and described signal lamp is connected with micro controller system P0.3 port, but this patent also the signalization lamp be connected with micro controller system P0.3 port and remind.
The utility model is a kind of safety belt prompt device, can be first according on the seat, whether someone determines whether the needs prompting when it uses, whether fasten the safety belt according to passengers inside the car again and remind accordingly, after using, common people can fasten the safety belt, thereby can reduce the safety misadventure that produces because of safety belt buckling free, improve the safety of driving.
Description of drawings
Fig. 1 is this patent structure connection diagram;
Member in figure is:
1, micro controller system; 2, infrared receiving device; 3, upper AND circuit;
4, pressure sensor; 5, movable switch; 6, lower AND circuit;
7, signal lamp; 8, aerotron; 9, verbal cue device;

The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail:
Whether the utility model can fasten the safety belt to passengers inside the car and remind, thereby can reduce the safety misadventure that produces because of safety belt buckling free by a kind of safety belt prompt device of design.
provide structure connection diagram a kind of safety belt prompt device as shown in Figure 1 as a kind of specific embodiment the utility model of the utility model, comprise micro controller system 1, infrared receiving device 2, upper AND circuit 3, pressure sensor 4, movable switch 5, lower AND circuit 6 and aerotron 8, described infrared receiving device 2 is connected with micro controller system 1P3.0 port by upper AND circuit 3, described pressure sensor 4 is connected with the vacant port of micro controller system 1, described movable switch 5 has two grades, if do not insert safety strap, movable switch 5 is got to 1 grade, described movable switch 5 is connected with micro controller system 1P3.1 port by lower AND circuit 6, described aerotron 8 base stages are connected with micro controller system 1P0.3 port, described precaution device is connected with the other two-stage of aerotron 8, described precaution device comprises verbal cue device 9 and loudspeaker 10, the this patent precaution device can use the verbal cue mode to carry out early warning., producer can select according to actual needs, described safety belt prompt device also comprises signal lamp 7, described signal lamp 7 is connected with micro controller system 1P0.3 port, but this patent also signalization lamp 7 be connected with micro controller system 1P0.3 port and remind.
in this patent when work, is when the seat of taking in chaufeur or copilot, the pressure sensor 4 corresponding weight of input are to micro controller system 1, the program P0.1 that sets by micro controller system 1 exports a high level signal, infrared receiving device 2 receives signal output high level simultaneously, by upper AND circuit 3, high level signal is input to micro controller system 1P3.0 port, export high level by the corresponding program of micro controller system 1 at the P0.0 port again, if at this moment do not insert safety strap, movable switch 5 is got to 1 grade, input high level, by corresponding program in P0.3 port output low level, at this moment precaution device is started working, play by loudspeaker 10 suggestion voice of having set, simultaneously at P0.2 port output high level, red light lights.
The utility model is a kind of safety belt prompt device, can be first according on the seat, whether someone determines whether the needs prompting when it uses, whether fasten the safety belt according to passengers inside the car again and remind accordingly, after using, common people can fasten the safety belt, thereby can reduce the safety misadventure that produces because of safety belt buckling free, improve the safety of driving.
The above; it is only preferred embodiment of the present utility model; be not to be the utility model to be done the restriction of any other form, and according to any modification or equivalent variations that technical spirit of the present utility model is done, still belong to the utility model scope required for protection.
