Description

Detection Controller of Motorcycle Directional Lights

technical field

The invention relates to a detection controller of a motorcycle direction light, in particular to a detection controller capable of improving the universality of motorcycle direction light lamps.

Background technique

Motorbike 1 is in order to maintain the safety of its driving, and under the standard of traffic law, must be provided with warning lamps, as shown in Figure 1, motorcycle 1 has front direction lamp 11 at least in front device, and on motorcycle 1 The rear direction lamp 12 is set at the rear, and the motorcycle 1 passes through the front and rear direction lamps 11,12. When motorcycle 1 wanted to turn left, the front left direction lamp 11a and the rear left direction 12a of the left side were energized and lighted. 11 and 12 act in a flashing manner, so the traffic regulations stipulate that the flashing frequency of the direction lights must be within the frequency of 85-100 times per minute.

Commonly used directional lights 11 and 12 use light bulb L as the light source, use the detection controller 2 to control the conduction and shutdown of the light bulb L, and can detect whether the light bulb L is damaged at the same time, and use this to make the directional lights 11 and 12 reach the speed per minute. 85 to 100 flashes of frequency regulations. As shown in FIG. 2 , a commonly used detection controller 2 is composed of a positive power supply control circuit 21 , a voltage stabilizing circuit 22 , a negative power supply control circuit 23 , a micro-resistance circuit 24 , and a power supply control circuit 25 .

The power control circuit 25 is a relay. When the relay is turned on, the light bulb L can obtain power and light up. When the relay is turned off, the light bulb L is powered off and turned off. The micro-resistance circuit 24 can supply the positive power of the power control circuit 25, controlled by the positive power controller 21 composed of a capacitor 211 and a transistor 212, and then supplied to the power control circuit 25 by the micro-resistance circuit 24. The negative power supply is supplied by the negative power controller 23 composed of a capacitor 231 and a transistor 232 .

Commonly used detection controller 2 action is to provide power by positive electricity control circuit 21, through micro-resistance circuit 24, to power supply control circuit 25, make the capacitor 231 of negative electricity control circuit 23 charge simultaneously, in the charging stage of capacitor 231, by micro The resistance control circuit 24 supplies power to cause a difference in the potential difference between the two ends of the relay of the power control circuit 25, and the relay of the power control circuit 25 will form a suction state, and the power supply is turned on to make the bulb L emit light. The capacitor 231 of 23 will be discharged after being fully charged. With the help of the discharge of the capacitor 231, the potential difference between the two ends of the relay of the power control circuit 25 becomes the same, so that the relay of the power control circuit 25 jumps off, and the power control circuit 25 will not Power is then supplied to the light bulb L to turn off the light bulb L. In addition, in order to allow the driver to know whether the light bulbs L of the direction lights 11, 12 of the motorcycle 1 are normal, the commonly used warning action for detecting the damage of the light bulbs L of the controller 2 is when a light bulb L in the direction lights 11, 12 is damaged. When the load becomes smaller, the charging time of the capacitor 231 of the negative controller 23 will be shortened, and the frequency of charging and discharging of the capacitor 231 will be accelerated, so that the flickering frequency of other good light bulbs L will also become faster, so that the light bulb L can be reached. The warning function of L damage. Although the commonly used electronic controller 2 has been able to achieve the function of controlling the direction lights 11 and 12, the light bulb L is a light fixture that consumes more power, and the light-emitting diode (LED) is a light bulb that saves power and has high brightness. Sufficient lamps and lanterns, the load power that can be sensed by the power controller 25 of the commonly used detection controller 2 needs to be at least 2W, so that the relay of the power controller 25 can operate normally, but the energy consumption (ie power) of the LED is only 0.2 W is about W, so the commonly used detection controller 2 cannot be used on the direction lights of LED lamps at all, and there is a need for improvement. Therefore, some manufacturers have developed an analog power method to make the commonly used detection controller 2 suitable for LED lamps. As shown in Figure 3, the analog power method is realized by using LED lamps 26 as loads, and the LED lamps 26 are connected in series or in parallel. connection, and an auxiliary load 27 is set on the side of the LED lamp 26, by means of the auxiliary load 27, the overall load reaches the power required for the normal operation of the relay of the power controller 25, but the power consumption of the LED lamp 26 is only 0.2W, so even if all the LED lamps 26 are completely damaged, the relay of the power controller 25 cannot be operated normally. Unless the auxiliary load 27 is also damaged, the relay of the power controller 25 can be operated normally to generate a warning function. Therefore, the analog power mode of the commonly used detection controller 2 still cannot effectively solve the problem that LED lamps are suitable for direction lights, so how to provide a detection controller suitable for LED lamp direction lights to improve the performance of motorcycle direction light lamps? Versatility is really a worthwhile direction for motorcycle manufacturers to develop.

The micro-resistance circuit 34 can supply the positive power of the power control circuit 35, controlled by the positive power controller 31 composed of a capacitor 311 and a transistor 312, and then supplied to the power control circuit 35 by the micro-resistance circuit 34. The negative power supply is supplied by a negative power controller 33 composed of a capacitor 331 and a transistor 332 .

The action of detecting controller 3 is to provide power by the positive electricity control circuit 31, through the micro-resistance circuit 34, to the power control circuit 35, and the capacitor 331 of the negative electricity control circuit 33 is charged at the same time, in the charging stage of the capacitor 331, by the micro-resistance The control circuit 34 supplies power to cause a difference in the potential difference between the two ends of the relay of the power control circuit 35, and the relay of the power control circuit 35 will form a sucking state, and then turn on the power of the auxiliary load circuit 36 to make the LED lamp 361 To emit light, the auxiliary load circuit 36 at least includes a group of LED lamps 361, an auxiliary load 362, and a transistor 363, and the LED lamps 361 are connected in series. After the capacitor 331 of the negative electricity control circuit 33 is fully charged, it will discharge. By means of the discharge of the capacitor 331, the potential difference at the two ends of the relay of the power control circuit 35 becomes the same, so that the relay of the power control circuit 35 is tripped, and the power control circuit 35 will no longer supply power to the auxiliary load circuit 36, and then the LED lamp 361 in the auxiliary load circuit 36 will be extinguished. In addition, in order to allow the driver to know whether the light bulbs of the direction lights of his motorcycle are normal, the bulb damage warning action of the detection controller 3 is that when any LED lamp 361 is damaged in the direction lights, all LED lights will be caused to be damaged. Lamp 361 is not bright, when power cannot be delivered to transistor 363 by LED lamp 361 end, even if auxiliary load 362 is not damaged, this transistor 363 also becomes power-off state, and then the charging time of capacitor 331 of negative electricity controller 33 is shortened, The frequency of charging and discharging of the capacitor 331 is accelerated, so the flickering frequency of other good direction lights can also be accelerated, and the warning effect of bulb damage can be achieved.

The detection controller 3 of the motorcycle direction light of the present invention mainly makes the overall load meet the basic driving power of the relay of the power supply control circuit 35 by setting the auxiliary load 362 on the auxiliary load circuit 36, and then passes on the auxiliary load circuit 36.
