[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example 1

[0023] The present embodiment discloses an automatic turning-off device for a two-wheeled vehicle turn signal, comprising a turn signal switch 1, a control module 2 and a wheel speed module 3 connected in sequence, wherein the turn signal switch 1 and the control module 2 are both connected to the turn signal 4, the turn signal switch 1 is used to switch the working state of the turn signal 4, and the wheel speed module 3 is used to collect the wheel speeds of the front and rear wheels of the two-wheeled vehicle in real time; the control module 2 detects and controls the turn signal 4 to be turned on or off according to the state of the turn signal switch 1, and controls the turn signal to be turned off according to the wheel speeds of the front and rear wheels of the two-wheeled vehicle. Specifically, the turn signal switch 1 is connected to the turn signal 4 via a flasher 5, and the flasher 5 is used to indicate a change in the driving direction of the two-wheeled vehicle.

[0024] In one embodiment, the wheel speed module 3 includes a front wheel speed sensor and a rear wheel speed sensor, the front wheel speed sensor is arranged on the front wheel of the two-wheel vehicle, and the rear wheel speed sensor is arranged on the rear wheel of the two-wheel vehicle, and the front wheel speed sensor and the rear wheel speed sensor are both connected to the control module 2, and the real-time collected front and rear wheel speeds are fed back to the control module 2. The wheel speed is the vehicle speed multiplied by the radius of the tire.

[0025] In one embodiment, the control module 2 includes a steering switch state detection circuit connected to the steering switch 1 for detecting whether the steering switch 1 is turned on or off.

[0026] like Figure 2 The steering switch state detection circuit includes a resistor R1, a resistor R2, a resistor R3, a capacitor C1, a capacitor C2 and a transistor Q1, the resistor R1 is connected to the steering switch, the resistor R4 is connected to the MCU of the control module 2, and the left steering switch state detection circuit and the right steering switch state detection circuit are designed the same.

[0027] In one embodiment, the control module 2 also includes a left turn signal control circuit and a right turn signal control circuit. The input end of the left turn signal control circuit is connected to the MCU of the control module, and the output end of the left turn signal control circuit is connected to the left turn signal 41. When the MCU of the control module detects through the steering switch status detection circuit that the left turn signal switch is turned on, it sends a working signal to the left turn signal control circuit to control the left turn signal 41 to light up; when the MCU of the control module detects through the steering switch status detection circuit that the left turn signal switch is turned off, it sends a stop working signal to the left turn signal control circuit to control the left turn signal 41 to turn off.

[0028] The input end of the right turn signal control circuit is connected to the MCU of the control module, and the output end of the right turn signal control circuit is connected to the right turn signal 42. When the MCU of the control module detects through the steering switch status detection circuit that the right turn signal switch is turned on, it sends a working signal to the right turn signal control circuit to control the right turn signal 42 to light up; when the MCU of the control module detects through the steering switch status detection circuit that the right turn signal switch is turned off, it sends a stop working signal to the right turn signal control circuit to control the right turn signal 42 to turn off.

[0029] like Figure 3 The left turn signal control circuit includes resistor R5, resistor R6, resistor R7, resistor R8, resistor R9, resistor R10, resistor R11, capacitor C3, transistor Q2, transistor Q3 and MOS tube Q4. Resistor R5 is connected to the MCU of control module 2, and MOS tube Q4 is connected to the turn signal.

[0030] When the state of the left (right) turn switch changes, the left (right) turn signal needs to be turned on or off. When the MCU of the control module 2 detects the state change through the steering switch state detection circuit, it controls the turn signal control circuit to work or stop working, thereby controlling the left (right) turn signal to work or stop working. Among them, the right turn signal control circuit is designed the same as the above-mentioned left turn signal control circuit, which will not be repeated here.

[0031] Specifically, the MCU of the control module 2 processes the collected front and rear wheel speeds. When the speed difference between the front and rear wheel speeds within a preset time is less than a preset value and the right turn signal switch is turned on, a stop working signal is sent to the right turn signal control circuit to control the right turn signal to turn off. Similarly, when the speed difference between the front and rear wheel speeds within a preset time is less than a preset value and the left turn signal switch is turned on, a stop working signal is sent to the left turn signal control circuit to control the left turn signal to turn off. Among them, calculating the speed difference between the front and rear wheels and judging whether the speed difference is less than a preset value within a preset time are both existing technologies and will not be repeated here.

[0032] Specifically, it also includes a 12V battery 6, which is connected to the steering switch 1 and is used to power the steering switch state detection circuit, the left turn signal control circuit, the right turn signal control circuit, the front wheel speed sensor, the rear wheel speed sensor, and the left and right turn signals.

[0033] When the driver manually turns on the left (right) steering switch to turn the two-wheeled vehicle, the control module obtains the front wheel speed and the rear wheel speed in real time through the front wheel speed sensor and the rear wheel speed sensor, processes the front wheel speed and the rear wheel speed, and sends a stop signal to the left (right) steering light control circuit when the speed difference between the front wheel speed and the rear wheel speed is less than the preset value, controls the left (right) steering light to turn off, realizes the automatic turning off of the steering light, and improves driving safety. At the same time, the turning switch can also be detected to turn off the state, send a stop signal to the left (right) steering light control circuit, control the left (right) steering light to turn off, and realize the manual turning off of the steering light.

[0034] The utility model can realize automatic turning off of the turn signal lamp, eliminating the need for the driver to turn off the turn signal lamp after the vehicle turns, so that the driver can concentrate more on controlling the driving speed and direction according to the new road conditions after turning, thereby improving driving safety; it prevents the driver from forgetting to turn off the turn signal lamp after the vehicle turns, thereby avoiding related traffic accidents; in addition, by automatically turning off the turn signal lamp, the driver's operating steps are simplified, the difficulty of driving operation is reduced, and driving safety is improved.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
