Description
Technical field
The utility model relates to a kind of control circuit that is used for automotive lamp, more particularly, relates to a kind of automobile brake lamp intelligence control circuit that has alarm function concurrently.
Technical background
The control circuit that tradition is used for automotive lamp is when the vehicle driver touches on the brake, stoplight stop lamp is directly bright, do not glimmer, thereby the prompting after the vehicle driver, but after the vehicle driver can not distinguish the preceding that the vehicle driver is emergency brake or normal braking, thereby be unfavorable for that the driver makes accurate judgement, and can not guarantee safe driving, cause traffic accident easily.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective of the prior art, provide a kind of after the vehicle driver distinguish the preceding that the vehicle driver is emergency brake or normal braking, be convenient to the driver and make accurate judgement, guarantee the automobile brake lamp intelligence control circuit of safe driving.
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of automobile brake lamp intelligence control circuit is provided, comprise power supply, with power supply bonded assembly LED stoplight stop lamp, left steering lamp, right steering lamp, also comprise and power supply bonded assembly voltage stabilizer, with voltage stabilizer bonded assembly microcontroller, described microcontroller is provided with the brake signal input interface, microcontroller is connected with an acceleration pick-up, first output interface of microcontroller is connected with aerotron Q1, Q2, and aerotron Q2 is connected with the LED stoplight stop lamp; Second output interface of microcontroller is connected with aerotron Q3, and aerotron Q3 is connected with the left steering lamp; The 3rd output interface of microcontroller is connected with aerotron Q4, and aerotron Q4 is connected with the right steering lamp.
The beneficial effect of automobile brake lamp intelligence control circuit described in the utility model is: by the brake signal input interface is set at microcontroller, microcontroller is connected with an acceleration pick-up, first output interface of microcontroller is connected with aerotron Q1, Q2, and aerotron Q2 is connected with the LED stoplight stop lamp; Second output interface of microcontroller is connected with aerotron Q3, and aerotron Q3 is connected with the left steering lamp; The 3rd output interface of microcontroller is connected with aerotron Q4, and aerotron Q4 is connected with the right steering lamp.After the vehicle driver distinguish the preceding that the vehicle driver is emergency brake or normal braking, be convenient to the driver and make accurate judgement, prevention is knocked into the back, and guarantees safe driving.
Below in conjunction with drawings and Examples automobile brake lamp intelligence control circuit described in the utility model is described further.
Description of drawings
Fig. 1 is the schematic circuit diagram of automobile brake lamp intelligence control circuit described in the utility model.
The specific embodiment
Below the preferred example of automobile brake lamp intelligence control circuit described in the utility model, therefore do not limit protection domain of the present utility model.
With reference to Fig. 1, a kind of automobile brake lamp intelligence control circuit is provided, comprise power supply 1, with power supply 1 bonded assembly LED stoplight stop lamp 2, left steering lamp 3, right steering lamp 4, also comprise and power supply 1 bonded assembly voltage stabilizer 5, with voltage stabilizer 5 bonded assembly microcontrollers 6, described microcontroller 6 is provided with the brake signal input interface, microcontroller 6 is connected with an acceleration pick-up 7, and first output interface of microcontroller 6 is connected with aerotron Q1, Q2, and aerotron Q2 is connected with LED stoplight stop lamp 2; Second output interface of microcontroller 6 is connected with aerotron Q3, and aerotron Q3 is connected with left steering lamp 3; The 3rd output interface of microcontroller 6 is connected with aerotron Q4, and aerotron Q4 is connected with right steering lamp 4.
Described microcontroller 6 also comprises an internal memory 8.
Described microcontroller 6 also is connected with a reset switch 9.
When braking automobile, acceleration pick-up 7 is exported different G values to microcontroller 6, microcontroller 6 judges according to the size of G value whether automobile belongs to emergency brake, if emergency brake, with microcontroller 6 first output interface bonded assembly aerotron Q1, Q2 sends 2 flickers of fast blink signal driving LED stoplight stop lamp, simultaneously, sending at a slow speed with microcontroller 6 second output interface bonded assembly aerotron Q3, flash signal drives the flicker of left steering lamp, send at a slow speed flash signal with microcontroller 6 the 3rd output interface bonded assembly aerotron Q4 and drive the flicker of right steering lamp, thus prompting after the vehicle driver be emergency brake.If do not belong to emergency brake, to send straight bright signal driving LED stoplight stop lamp 2 directly bright with microcontroller 6 first output interface bonded assembly aerotron Q1, Q2, do not glimmer, do not work with microcontroller 6 second output interface bonded assembly aerotron Q3, with microcontroller 6 the 3rd output interface bonded assembly aerotron Q4, thus prompting after the vehicle driver be normal braking.
The foregoing description is the utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spirit of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
