Description

TECHNICAL FIELD The present invention relates to an acousto-optic dual warning device for automobiles, motorcycles, and mopeds. BACKGROUND OF THE INVENTION Existing sound and light dual warning devices for vehicles such as automobiles, motorcycles, and mopeds have two functions, that is, they emit an audible warning signal and a light warning signal. Although the acoustic signal is not affected by the angle, the transmission speed is slow and the transmission distance is short. When it is subjected to headwinds, it will affect the transmission of sound; 'Although the light signal is transmitted fast and the transmission distance is long, it is limited by the angle. In addition, the sound signal and the light signal are controlled by separate circuits. To send a signal, two different switches must be activated. For the driver, it is necessary to pay attention to the road condition at all times, and also to start the operation of the horn and the light switch. SUMMARY OF THE INVENTION The purpose of the present invention is to overcome the above-mentioned shortcomings, and to provide a dual sound and light warning device for a vehicle that can simultaneously emit sound and light signals by activating a horn switch.

The purpose of the present utility model is achieved by the following technical solution: A sound and light dual warning device for a vehicle includes a horn, a headlight, a horn switch, and a vehicle power source. The positive electrode of the vehicle power source is electrically connected to the speaker, and the negative electrode of the vehicle power source. It is electrically connected to the horn switch. The other end of the horn switch is electrically connected to the horn. The negative pole of the headlight is grounded. There are two paths between the positive pole of the vehicle power supply and the horn. One of them is electrically connected to the coil. The other end of the coil is connected to the horn switch. The other end is electrically connected to the relay switch, the other end of the relay switch is electrically connected to the diode, the other end of the diode is electrically connected to the positive electrode of the headlight, and the coil and the relay switch are configured as a light relay.

After the structure of the utility model is adopted, when the horn switch is closed, the relay switch is automatically closed due to the magnetic field of the coil, and the current flows from the positive electrode of the vehicle power supply to the headlight through the relay switch and the diode in order, while the horn emits an acoustic signal. The headlights also emit light signals. Therefore, compared with the prior art, the utility model can simultaneously emit sound and light signals, and has dual effects of sound and light. It makes up for the lack of separate use of the original horn and headlights, and starts on safe driving. To an important role. BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be further described in detail with reference to the accompanying drawings and embodiments. FIG. 1 is a schematic structural diagram of an acousto-optic dual warning device (for automobile) of the utility model;

Figure 2 is a schematic view showing the structure of a sound and light dual warning device (for motorcycles) of the utility model;

"'Figure 3 is a schematic structural diagram of an acousto-optic dual alarm device for acousto-optic dual warning device for a vehicle according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 2. Horn switch, vehicle power supply 3, the positive pole of vehicle power supply 3 is electrically connected to horn 1, 'the negative pole of vehicle power supply 3 is electrically connected to the horn switch (that is, the start of the horn is controlled by the negative pole), and the other end of the horn switch ^ is connected to The horn 1 is electrically connected, and the negative pole of the headlight 2 is grounded (that is, the headlight start is controlled by the positive pole). There are two paths between the positive pole of the vehicle power supply 3 and the horn 1, one of which is electrically connected to the coil L, and the other end of the coil L 1 ^ electrically connected to the horn switch, and the other path ₁₂ is electrically connected to the relay switch, the relay switch K ₂ is connected to the other end of the diode D is electrically, the other end of the diode D and the headlight 2 is electrically connected to the positive electrode; and the coil L The relay switch K _{2 is} configured as a light relay 4. For the convenience of use and wiring, the coil L, the relay switch K ₂ and the diode D are configured as an acousto-optic control relay assembly (5) (as shown in FIG. 3).

When the horn switch ^ is closed, the current returns from the positive pole of the vehicle power supply to the negative pole of the vehicle power supply through the horn and the horn switch Kt in this order. At this time, the horn emits an acoustic signal. Meanwhile, since the magnetic field of the coil of the relay switch K ₂ is closed automatically turn the vehicle from the current through the relay of the switching power supply positive Κ ₂ and flows to the diode D headlights, the horn audible signals simultaneously, will make light headlights There is also a current from the positive pole of the vehicle power supply to the negative pole of the vehicle power supply through the coil L and the horn switch in turn, when the horn switch! ^ When open, the relay switch K ₂ is also in the open state. In addition, the headlight also has a dedicated independent control circuit (the original circuit of the car, which is no longer shown in the figure). When the control circuit starts, due to the reverse cut-off effect of the diode D, the headlight emits a light signal. The horn will not emit an acoustic signal along with it.

For the same reason, the sound and light warning device used in automobiles is also applicable to vehicles such as motorcycles and mopeds. The circuit connection is shown in Figure 2.
