DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0037] The core of the present application is to provide a turning warning device, which not only has a light turning indication but also has a voice warning during the turning of a vehicle, and the siren and the light indication control circuit are independently arranged, so that the phenomenon of intermittent siren voice caused by the timing on-off frequency of the flasher can be avoided. Another core of the present application is to provide a vehicle comprising the above turning warning device and a control method suitable for the above turning warning device.

[0038] Please refer to Figures 1-4 , Figure 1 The structural schematic diagram of the specific embodiment of the turning warning device provided by the present application is shown in the figure. Figure 2 The circuit structural schematic diagram of the flasher in the turning warning device provided by the present application is shown in the figure. Figure 3 The schematic diagram of the output waveforms of the first output pin and the second output pin is shown in the figure. Figure 4 The flowchart of the specific embodiment of the control method provided by the present application is shown in the figure.

[0039] The turning warning device provided by the present embodiment comprises a power supply, a left turn signal 1, a right turn signal 2, a siren 3 and a flasher 4, wherein the flasher 4 is connected with the power supply; the flasher 4 is internally provided with a light warning circuit selectively connected with the left turn signal 1 and the right turn signal 2, a voice warning circuit connected with the siren 3, and a single-chip microcomputer circuit 10 for controlling the on-off of the light warning circuit and the voice warning circuit; and the light warning circuit and the voice warning circuit are both directly connected with the power supply, so as to avoid the influence of the timing on-off of the light warning circuit on the voice warning circuit.

[0040] In addition, for safety, the left turn signal 1, the right turn signal 2 and the alarm 3 can be connected with the ground.

[0041] Preferably, a fourth resistor 14 connected with the single-chip microcomputer circuit 10 can be provided, and the fourth resistor 14 is connected with the ground.

[0042] It should be noted that when the vehicle turns, the left turn signal 1 or the right turn signal 2 needs to be controlled to flash, that is, the light warning circuit is controlled to be powered on in a timing manner. If the alarm 3 is connected to the light warning circuit, the alarm 3 will have an intermittent voice during the working process, which affects the normal performance of the voice broadcast content and cannot play a good warning role.

[0043] During the use of the turning warning device provided by the embodiment, when the vehicle turns, the left turn signal 1 or the right turn signal 2 is connected with the light warning circuit, the alarm 3 is connected with the voice warning circuit, and since the light warning circuit and the voice warning circuit are both directly connected with the power supply, the left turn signal 1 or the right turn signal 2 will not affect the alarm 3 during the timing power-on process, so that the alarm 3 can normally broadcast the warning voice.

[0048] In use, when the light switch 5 is in the left or right communication position, and one of the left and right turn signals 1 and 2 is communicated, the first output pin 6 outputs a low level, and when the light switch 5 is in the off position, the first output pin 6 outputs a high level.

[0049] On the basis of the above embodiment, the first resistor 8 and the third resistor 9 are further included in parallel with the light warning circuit, one end of the first resistor 8 is connected with the single-chip microcomputer circuit 10, the other end is connected with the first switch 7, one end of the third resistor 9 is connected with the single-chip microcomputer circuit 10, the other end is connected between the first switch 7 and the first output pin 6.

[0050] The first resistor 8 and the third resistor 9 are both voltage dividing resistors.

[0051] The second switch 12 for controlling the on-off of the voice warning circuit and the second output pin 13 connecting the second switch 12 with the alarm 3 can be arranged in the voice warning circuit.

[0052] The second resistor 11 in parallel with the voice warning circuit is further included, one end of the second resistor 11 is connected with the single-chip microcomputer circuit 10, the other end is connected with the second switch 12.

[0053] When the light switch 5 is connected with one of the left and right turn signals 1 and 2, the first output pin 6 outputs a low level, the first switch 7 is turned on, the first output pin 6 outputs a square wave, the second switch 12 is turned on, and the second output pin 13 outputs a long electricity to make the alarm 3 broadcast the warning voice; when the light switch 5 is in the off position, the first output pin 6 outputs a high level, and no load is connected by default.

[0054] In addition to the above-mentioned turn warning device, the application further provides a control method suitable for the turn warning device disclosed in the above embodiment, the control method comprises:

[0058] Step S4, turn on the light warning circuit, make the first output pin 6 output a square wave, make the second output pin 13 output a long electricity, turn on the alarm 3 and broadcast the warning voice;

[0059] In the above step S4, the square wave can be a square wave of 416 ms, as shown in the following formula: Figure 3 The long electricity and the square wave correspond to each other.
