[0003] For the flashing frequency of turn signal lights, a stopwatch can be used to test the number of flashes within a specified time. However, currently, there is no dedicated measuring equipment that can meet the requirements of this technical clause for the first on / off time of turn signal lights. Usually, a stopwatch is used to measure, or an oscilloscope is used to test the voltage waveform at both ends of the turn signal lights to determine the first on / off time of turn signal lights.

[0004] Due to the limitation of human perception sensitivity, when using a stopwatch test, the light signal control switch opening time, the first light-off time and the stopwatch start-stop time cannot be synchronized, resulting in poor stopwatch test accuracy and test result consistency. Compared with the stopwatch test, the oscilloscope test can accurately judge the light signal control switch opening time and the first light-off time, which is completely better than the stopwatch in terms of test accuracy and test result consistency. However, the oscilloscope test equipment has high requirements for operators, the detection process is complicated, the test cycle is long, the result judgment is difficult, and the test efficiency is low.

[0037] At present, the flashing of motorcycle turn signal lights is realized by flashers. There are two main types of flashers in the motorcycle industry: three-wire type and two-wire type.

[0038] Figure 1A The working principle diagram of a three-wire flasher in the prior art is shown. Figure 1B yes Figure 1A As shown in the figure, the three-wire flasher can be regarded as a relay in essence. The two input terminals (control part) are connected in series with the turn signal switch in the circuit, and the turn signal flashing is controlled by turning on and off the third output terminal (execution part).

[0039] Figure 2A The working principle diagram of a two-wire flasher in the prior art is shown. Figure 2B yes Figure 2A As shown in the figure, the two-wire flasher can be regarded as a variable resistor in essence, which is connected in series with the turn signal and the turn signal switch in the circuit. Through its own control circuit, the equivalent resistance value (high resistance → low resistance → high resistance → low resistance...) changes alternately to change the voltage at both ends of the turn signal to control the flashing of the turn signal.

[0040] The technical requirement for turn signals in the GB18100 standard that "the light signal control switch should light up for the first time within 1 second after being turned on, and should go out for the first time within 1.5 seconds" is essentially a requirement for assessing the action characteristics of the flash relay.

[0041] Description of the turn signal operating status: initial state → turn signal switch is turned on → flasher is powered on but not operated → flasher operates (on, turn signal is on → off, turn signal is off → ...) → turn signal switch is turned off.

[0042] According to the motorcycle lighting and light signal system voltage of 12V, turn signal 12V5W×2, resistance 14.4Ω, the action status of the three-wire and two-wire flasher turn signal circuits are analyzed as follows:

[0043] (I) Analysis of the action states of the three-wire flasher:

[0044] 1. Preset conditions: flasher control part equivalent resistance 1KΩ; turn signal resistance 14.4Ω;

[0045] 2. Initial state: the turn signal switch is off, at this time the flasher and bulb circuit current I flash = I light = 0mA, and the oscilloscope current display I = 0mA;

[0046] 3. Turn signal switch is turned on: 3.1 flasher is powered on but does not work → 3.2 flasher is powered on and works (3.2.1 is on, turn signal is on → 3.2.2 is off, turn signal is off → on and off cycle…………);

[0047] 3.1. The flasher is powered but does not work: I flash = 12V ÷ 1kΩ = 12mA, I light = 0mA, and the oscilloscope current shows I = 12mA. At this time, the timing is t 1;

[0048] 3.2. The flasher will work after being powered on: I flash = 12V ÷ 1kΩ = 12mA, and I light will change as the flasher works;

[0049] The oscilloscope current display I also changes accordingly;

[0050] 3.2.1, turn signal on: I flash = 12V ÷ 1kΩ = 12mA, I light = 12V ÷ 14.4Ω = 833.33mA;

[0051] The current displayed on the oscilloscope is I = 12 + 833.33 = 845.33 mA. The timing at this time is t2;

[0052] 3.2.2 off, turn signal off: I flash = 12V ÷ 1kΩ = 12mA, I light = 0mA;

[0053] The oscilloscope current shows I = 12mA. The timing at this time is t3;

[0054] 4. Disconnect the steering switch: restore to the initial state, at this time the flash circuit and the bulb circuit current I flash = I light = 0mA, the oscilloscope current display I = 0mA;

[0055] 5. Conclusion: After the turn switch is turned on, according to the change of the oscilloscope current, the first lighting and extinguishing time of the turn signal after the turn switch is turned on can be tested to verify whether the turn signal meets the standard requirements:

[0056] First lighting time tlight = t2-t1;

[0057] The first off time t off = t3 - t1.

[0058] (II) Analysis of the action status of two-wire flasher:

[0059] 1. Preset conditions: flasher equivalent resistance high resistance 1KΩ / low resistance 0Ω; turn signal resistance 14.4Ω;

[0060] 2. Initial state: the turn signal switch is off, and the oscilloscope current shows I = 0mA;

[0061] 3. Turn signal switch is turned on: 3.1 flasher high resistance state (light off) - 3.2 flasher low resistance state (light on) - off and on cycle...);

[0062] 3.1. Flasher high resistance state: It is equivalent to a 1KΩ resistor connected in series with the turn signal in the circuit. The voltage across the turn signal is about 0.17V, which is not enough to light up the turn signal.

[0063] The oscilloscope current shows I = 12V ÷ (1KΩ + 14.4Ω) = 11.8mA;

[0064] The timing at this time is t1;

[0065] 3.2. The flasher changes from high resistance to low resistance: At this time, the equivalent resistance changes from high resistance 1KΩ to low resistance 0Ω, the voltage across the turn signal rises to the system voltage 12V, and the turn signal lights up;

[0066] The oscilloscope current display is I=12V÷14.4Ω=833.33mA. The timing at this time is t2;

[0067] 3.3. The flasher changes from low resistance to high resistance: At this time, the equivalent resistance changes from low resistance 0Ω to high resistance 1KΩ, the voltage across the turn signal lamp drops significantly from 12V, and the turn signal lamp goes out;

[0068] The oscilloscope current shows I = 12V ÷ (1KΩ + 14.4Ω) = 11.8mA.

[0069] The timing at this time is t3;

[0070] 4. Turn the steering switch off: restore to the initial state, the oscilloscope current display I = 0mA;

[0071] 5. Conclusion: After the turn switch is turned on, the first on and off time of the turn signal after the turn switch is turned on can be tested according to the change of the oscilloscope current to verify whether the turn signal meets the standard requirements:

[0072] First lighting time tlight = t2-t1;

[0073] The first off time t off = t3 - t1.

[0074] From the above analysis, it can be seen that how to accurately measure the three parameter values ​​of the turn signal switch turning on time t1, the first lighting time t2, and the first off time t3 is the key to measuring the first lighting time and the first off time of the turn signal.

[0075] Figure 3The structure diagram of a motorcycle turn signal lighting performance tester according to an embodiment of the utility model is shown. As shown in the figure, the utility model provides a motorcycle turn signal lighting performance tester 100, which mainly includes a signal acquisition unit, a timer 103 and a counter 104, a first timer 105 and a second timer 106, a first trigger relay 107, and a logic control unit.

[0076] The signal acquisition unit includes a conductive probe 101 and a light probe 102.

[0078] The first timer 105 is used to record the first lighting time of the turn signal lamp, and the second timer 106 is used to record the first extinguishing time of the turn signal lamp.

[0080] The logic control unit is connected to the IN terminals of the first timer 105 and the second timer 106. The logic control unit is also used to receive detection signals from the conductive probe 101 and the light probe 102, so that the first timer 105 and the second timer 106 respectively record the first lighting moment and the first extinguishing moment of the turn signal, eliminating the subsequent accumulated timing of the two.

[0081] Preferably, the logic control unit comprises a second trigger relay 108, a third trigger relay 109 and a fourth trigger relay 110. The logic control unit eliminates the problem of repeated timing of subsequent flashing by combining three trigger relays.

[0082] Specifically, the IN terminal of the second trigger relay 108 receives the detection signal of the light probe 102, and the NC terminal thereof is connected to the ON terminal and the IN terminal of the third trigger relay 109. The COM terminal of the second trigger relay 108 receives the detection signal of the conductive probe 101, and is connected to the COM terminals of the first to fourth trigger relays 107, 108, 109, 110. The ON terminal of the second trigger relay 108 is connected to the ON terminal and the IN terminal of the fourth trigger relay 110 and the DC+ terminal of the third trigger relay 109.

[0083] The NC terminal of the third trigger relay 109 is connected to the IN terminal of the second timer 106;

[0084] The NC terminal of the fourth trigger relay 110 is connected to the IN terminal of the first timer 105 .

[0085] Preferably, the first to fourth trigger relays 107, 108, 109, 110 are set to high level or low level trigger, and are activated when there is a trigger signal, and reset when the trigger signal is disconnected. When the first to fourth trigger relays 107, 108, 109, 110 are activated, the connection time between the COM terminal and the ON terminal is less than 10ms. More preferably, the first trigger relay 107 and the second trigger relay 108 are set to low level trigger action; the third trigger relay 109 and the fourth trigger relay 110 are set to high level trigger action.

[0086] Preferably, the motorcycle turn signal lighting performance tester 100 also includes a built-in 12V power supply 111. The positive pole of the built-in 12V power supply 111 is connected to the DC+ terminal of the timer 103, the counter 104, the first timer 105, the second timer 106, the first trigger relay 107, the second trigger relay 108 and the fourth trigger relay 110, and is connected to the COM terminal of the timer 103.

[0087] Preferably, the detection point A of the conductive probe 101 is located on the connection line from the turn signal switch to the turn signal, and is close to one side of the turn signal switch.

[0088] Preferably, the test duration set by the timer 103 is 15s to 30s, preferably 20s. If the number of flashes recorded by the counter 104 during the test duration is N times, the flashing frequency of the turn signal is 3N / min. Conventionally, the setting range of the timer 103 is 0.01s to 99.99s. The control method is that the trigger end receives a high level or low level signal. During the test duration, re-triggering is invalid, and it is reset when the test duration is completed. The working mode of the counter 104 is to display 000 after power-on. When the control signal changes from a low level to a high level, the counter 104 counts plus 1, and the control signal remains at a high level, or when the control signal changes from a low level, the counter 104 count remains unchanged, and the counter 104 is automatically cleared after power failure.

[0089] Preferably, the light probe 102 is a photodiode. According to the change of the on / off state of the turn signal, the photodiode outputs a trigger signal to the first timer 105 and the second timer 106 to trigger the timer to stop timing, and at the same time outputs a trigger signal to the counter 104 to control the counter 104 to record the number of times the turn signal is turned on. More preferably, the light resistance of the photodiode is less than 2.4KΩ, and the dark resistance is greater than 200MΩ.

[0090] refer to Figure 3 The motorcycle turn signal circuit includes a turn signal, a turn signal switch and a flasher. One end of the turn signal switch is connected to a 12V power supply, and the other end is connected in series with the flasher and the turn signal. The detection point A of the conductive probe 101 is located between the turn signal switch and the flasher. The voltage change at the detection point A is used to control the start of the first timer 105 and the second timer 106. The light probe 102 controls the NC terminal level change of the third trigger relay 109 and the fourth trigger relay 110 according to the on and off state of the turn signal, thereby finally controlling the first timer 105 and the second timer 106 to be in a timing state. When the NC terminals of the third trigger relay 109 and the fourth trigger relay 110 are at a low level, the first timer 105 and the second timer 106 enter a stop timing state.

[0091] According to the closed state of the motorcycle turn signal switch and the on and off state of the turn signal, the operation states of the first timer 105 and the second timer 106 are analyzed in combination with the logic control unit.

[0092] Table 1 Analysis of the action status of the first timer and the second timer

[0093]

[0094] Referring to Table 1, the test duration of the preset timer 103 is 20 seconds, and the test action process is as follows:

[0095] 1) After the turn signal switch is closed, the voltage at point A becomes +12V, the detection signal of the conductive probe 101 triggers the timer 103 to start, the COM terminal of the timer 103 is connected to the 0N terminal, the NC terminal of the third trigger relay 109 and the fourth trigger relay 110 is triggered to be high level, the first timer 105 and the second timer 106 start timing, and the turn signal switch is turned on at time t1;

[0096] 2) When the turn signal lamp is turned on for the first time, the NC terminal of the fourth trigger relay 110 is triggered to be low level, the first timer 105 stops timing, and displays the first lighting time t2, the second timer 106 continues timing, and the flash count counter 104 displays the counted number as [1];

[0097] 3) When the turn signal lamp is turned off for the first time, the NC terminal of the third trigger relay 109 is triggered to be low level, the first timer 105 keeps stopping timing and displays the first lighting time t2, the second timer 106 stops timing and displays the first turning off time t3, the flashing times counter 104 stops counting and displays the count times as [1];

[0098] 5) When the turn signal lamp is turned on for the second time, the first timer 105 stops timing and displays the first time of lighting t2, the second timer 106 stops timing and displays the first time of turning off t3, and the flash count counter 104 displays the count count as [2];

[0099] 6) When the turn signal lamp is turned off for the second time, the first timer 105 stops timing and displays the first lighting time t2, the second timer 106 stops timing and displays the first turning off time t3, and the flashing times counter 104 pauses counting and displays the count times as [2];

[0100] 7) The turn signal lamp flashes continuously within the 20-second timer set by the built-in timer 103, the first timer 105 stops timing and displays the first lighting time t2, the second timer 106 stops timing and displays the first extinguishing time t3, each time the turn signal lamp lights up, the flashing times counter 104 displays the count times + 1, each time the turn signal lamp turns off, the flashing times counter 104 pauses and the displayed times remain;

[0101] 8) The timer 103 is set to expire at 20 seconds, the timer 103 is reset, the C0M terminal of the timer 103 is disconnected from the ON terminal, the first timer 105 stops timing and displays the first lighting time t2, the second timer 106 stops timing and displays the first lighting time t3, and the counter 104 displays the total number of counts within 20 seconds [N]. That is, except for the first flash light on and off, the subsequent flash light on and off has no effect on the first timer 105 and the second timer 106. The first timer 105 displays the first lighting time t2, and the second timer 106 displays the first off time t3. Since the starting point of the first timer 105 and the second timer 106 is the turn signal switch on time t1, the first lighting time t2 and the first off time t3 are the lighting time and the first off time after the optical signal control switch is turned on as required by the test.

[0102] From the above action analysis, it can be known that after the turn signal switch is closed, the value displayed by the first timer 105 is the first lighting time t2 of the turn signal, and the value displayed by the second timer 106 is the first off time t3 of the turn signal, and the flashing frequency f=3N times / min.

[0103] According to the technical requirements of GB18100 "Motorcycle Lighting and Light Signal Device Installation Regulations" series standards, "the flashing frequency should be (90+30) times / min; the light signal control switch should light up within 1s after turning on and go out for the first time within 1.5s", the judgment criteria according to the above test scheme are as follows:

[0104] First lighting time t2: ≤1s qualified;

[0105] First extinguishing time t3: ≤1.5s qualified;

[0106] Number of flashes in 20 seconds N: 20 to 40 times is acceptable.

[0107] The utility model provides a motorcycle turn signal lighting performance tester, which has the following advantages:

[0108] The overall structure is compact;

[0109] A logic control unit is provided to test the first on and off time of the turn signal lamp after the turn signal lamp switch is turned on;
