Illustrated in figures 1 and 2, automobile-use emergency brake signalling apparatus comprises deceleration/decel sensor 3, SCM program control circuit 4 and 5 three main portions of signal aspect and indication LED matrix.Deceleration/decel sensor 3 is used for measuring the variation of the speed of a motor vehicle; When emergency brake or contingency, the speed of a motor vehicle can reduce sharply, and when the changing value of deceleration/decel reached preset value in the IC program 11, it excited sequence circuit 4, makes signal aspect and indication LED matrix 5 send the emergency brake signal.The brake signal system 1 of the input signal cable of this device and self-propelled vehicle is connected in series, and to realize its automatic guidance, simultaneously, also the safety switch 2 with self-propelled vehicle is connected in parallel, to realize its manual control.
SCM program control circuit 4 is again by IC control circuit 6, power control circuit 7, and the control circuit 8 of signal aspect and indication LED matrix 5, the control circuit 9 of sensor 3 and delay control circuit 10 are formed.Wherein, power control circuit 7 links with above-mentioned control circuit, provides the power supply that is complementary according to the requirement of these control circuits for them; Deceleration/decel sensor 3 is by control circuit 9 control, and the deceleration/decel changing value that its collecting sensor records also sends to IC control circuit 6 with these parameters.6 li of IC control circuits, preset value in these parameters that obtained and the IC program 11 that designs compares, when the changing value of deceleration/decel reached preset value in the IC program 11, it excited sequence circuit 4, makes signal aspect and indication LED matrix 5 send the emergency brake signal.
Fig. 3 is IC program 11 control principle figure .18. power supplies, 19. initialization, and 20.LED all extinguishes, did the variation of 21. car deceleration degree reach preset value X km/ hour?, if N (denying), operation 22, at this moment, automobile is in normal condition; 23. open night-light?, Y (being) then enters 24, and this moment, all LED sent the low light level (night-light signal), was N (denying) as before, then crossed over 24, operation 25; 25. touch on the brake?, Y (being), operation 26, this moment, all LED sent high light (common brake signal), was N (denying) as before, then got back to 18; Move once more according to said procedure.At 21 places, did the variation of car deceleration degree reach preset value X km/ hour? Y (being), the automobile car enters the emergency brake state, and 28. counting machines equal zero, 29.LED show the emergency brake signal, 30. counting machine equals 60?, Y (being), 31. counting machines return zero, be N (denying) as before, continue to show the emergency brake signal; 32. it is in automobile enters dotted line during the emergency brake state, no matter open night-light and still touch on the brake, all invalid.
Fig. 4, shown in Figure 5, emergency signal LED matrix 5 are made up of the variable color light-emitting diode, and its arrangement mode has 15 two kinds in linear LED matrix 12 or annular LED matrix.
Fig. 4 again when SCM program control circuit 4 and LED matrix 12 are made of one, adopts flexible printed circuit board, by plastic packaging transparent, flexible, can dispel the heat, 4-8mm is thick, in the oval-shaped plastic cement, forms the linear matrix signal device 14 of emergency brake LED; Therebetween, LED matrix 5 is moved and glimmers to two ends by the centre according to the frequency of setting, simultaneously according to setpoint frequency conversion led color under the control of control circuit 9 and delay control circuit 10.
Fig. 5, Fig. 6 and shown in Figure 7, SCM program control circuit 4 is made of one with many ring quasi arrays of LED 15, adopts hard printed circuit board, is placed in the single or double lampshade, both looping emergency brake signalling apparatus 16 or 17; In like manner, LED matrix 5 is moved by interior hoop outer shroud and glimmers the led color of conversion simultaneously according to the frequency of setting under the control of control circuit 9 and delay control circuit 10.
Power control circuit 7 is used for controlling and producing required loss in voltage, and it links to each other with all control circuit, and provides the power supply that is complementary according to the demand of each control circuit for them; Sensor control circuit 9 is used for controlling sensor and excites the IC control circuit.
The utility model is divided into portable again according to mounting means, sheet type and built-in.Sheet type adopts the linear matrix of LED, and its attachment point example is onboard seen Fig. 8, is mainly used in existing C-class etc.; Built-in and portable employing LED ring quasi array becomes to be used for the new car exploitation or replaces the taillight that has truck now.Under the control of control circuit 4, they also have the function of common stoplight stop lamp and night-light simultaneously except the function with emergency brake lamp.
Working process of the present utility model: if common brake, when chaufeur steps down in pin on the brake pedal, the BK Brake Switch closure, original stoplight stop lamp (left, center, right) is bright, this moment is mild because of braking, the preset value of speed sensor 3 out of reach deceleration/decels, emergency brake signal LED matrix 5 does not work.Automobile is in emergency brake or when running into accident, and the speed of a motor vehicle can reduce sharply, and when deceleration/decel reaches the preset value of sensor 3, sensor will excite SCM program control circuit 4, make LED matrix 5 send the emergency brake signal.When automobile runs into collision, blow out, overturn, or when causing vehicle seriously to shake because of road bump, even have little time to touch on the brake, sensor 3 still can detect the variation of the speed of a motor vehicle and excite SCM program control circuit 4, starts emergency brake signal LED matrix 5 and reports to the police., can press safety switch 2 and realize manually reporting to the police because fault is parked on the road surface or during the roadside, bump against with it for preventing back vehicle when automobile.
