[0019] 1. The micro processing unit and the infrared distance sensor are arranged, the rotation angle of the movable frame is detected through the infrared distance sensor, so that the turn signal is controlled to be turned off. When the turn signal is turned on, the infrared distance sensor detects that the movable frame is turned beyond a certain angle and then returns to the original position, the turn signal is turned off, and the turn signal is automatically turned off instead of manually turned off, so that the situation of forgetting to turn off the turn signal during riding is reduced, and the safety of riding is improved.

DETAILED DESCRIPTION
[0027] The present application will be further described in detail below in combination with the drawings and embodiments.
[0028] The embodiment of the present application discloses a follow-up turn back device based on infrared diffuse reflection. Referring to Figures 1 to 4The utility model relates to a kind of steering lamp control system, including fixed to the main frame fixed rod 1 of vehicle body, main frame fixed rod 1 is equipped with the movable frame 2 of connecting car tap, movable frame 2 rotates in main frame fixed rod 1.Movable frame 2 includes handle 21 and connecting frame 22, handle 21 is connected connecting frame 22, handle 21 rotates and drives connecting frame 22 to rotate.
[0029] It also includes infrared distance sensor 3 and micro processing unit 4, infrared distance sensor 3 is located in the side wall of main frame fixed rod 1, infrared distance sensor 3 is electrically connected to micro processing unit 4, micro processing unit 4 receives input signal 7 and outputs control signal 8 to control the opening and closing of steering lamp.Connecting frame 22 is equipped with arc plate 5, arc plate 5 is located in the side of connecting frame 22 close to infrared distance sensor 3, infrared distance sensor 3 is towards arc plate 5, infrared distance sensor 3 is used for the side of arc plate 5 to detect the rotation angle of arc plate 5, to indirectly detect the rotation angle of movable frame 2, and send steering return signal 6 to micro processing unit 4, micro processing unit 4 is used to output control signal 8 to control the opening and closing of steering lamp.
[0030] Input signal 7 includes left turn signal on signal 71 and right turn signal on signal 72, control signal 8 includes left turn control output signal 81, right turn control output signal 82 and steering lamp off signal 83, when micro processing unit 4 receives left turn signal on signal 71, micro processing unit 4 outputs left turn control output signal 81 to control the opening of left turn signal.
[0031] In actual use, when left turn signal is not opened, left turn signal on signal 71 received by micro processing unit 4 is low flat voltage signal, when left turn signal is opened, left turn signal on signal 71 received by micro processing unit 4 is high flat voltage signal.
[0032] When movable frame 2 rotates so that the rotation angle detected by infrared distance sensor 3 is less than or equal to preset angle, sensor signal 9 outputs high flat voltage, when movable frame 2 rotates so that the rotation angle detected by infrared distance sensor 3 is greater than preset angle, sensor signal 9 outputs low flat voltage.When arc plate 5 leaves the detection area of infrared distance sensor 3 and returns to the detection area, sensor signal 9 changes from low flat voltage to high flat voltage at this time, this signal is steering return signal 6, sensor signal 9 sends steering return signal 6 to micro processing unit 4 at this time.In actual use, the duration of low flat voltage signal in steering return signal 6 needs to be greater than 1s.The range of high flat voltage is 2V to 5V, and the range of low flat voltage is 0V to 0.8V.
[0033] When the turn light is on, the micro-processing unit 4 receives the turn back signal 6, and the low flat voltage duration exceeds 1 second, the micro-processing unit 4 outputs the turn light off signal 83 to control the turn light to be off. In this application, the central angle of the arc plate 5 is 30 degrees, and the preset angle is 15 degrees.
[0034] The implementation principle of the follow-up turn back device based on infrared diffuse reflection in the embodiment of the application is as follows: in actual use, when the rider pulls the turn switch, the micro-processing unit 4 receives the left turn light on signal 71 or the right turn light on signal 72, and the corresponding turn light is turned on.
[0035] When the rider turns the handle 21, the infrared distance sensor 3 detects the turning angle of the arc plate 5. When the detected turning angle is less than 15 degrees, the sensor signal 9 outputs a high flat voltage. When the detected turning angle is greater than 15 degrees, the sensor signal 9 outputs a low flat voltage. When the low flat voltage lasts for more than 1 second and then the sensor signal 9 changes from the low flat voltage to the high flat voltage, the sensor signal 9 sends the turn back signal 6 to the micro-processing unit 4, and the micro-processing unit 4 turns off the corresponding turn light.
[0036] After completing a single turn, the handle 21 returns to the straight-ahead state, the left turn light on signal 71 and the right turn light on signal 72 are in the low flat voltage signal state, and then if the turn light is turned on, the corresponding left turn light on signal 71 or right turn light on signal 72 changes to the high flat voltage signal state, and the above operation is repeated during turning.
[0037] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, so: any equivalent changes made on the basis of the structure, shape, principle of the application should be covered within the protection scope of the application.
