Abstract

An apparatus for controlling an automotive horn is provided to prevent a contact operation failure of a horn due to foreign material. An automotive horn control device(300) includes a coil power supply unit(310) and a power supply control unit(320). The coil power feeder is connected to one end of a coil wound around a core. The coil power supply unit supplies the power. The power supply controller performs a switching operation when the power is applied. The power supply controller controls the current flow of the power supply controller. The power supply controller includes a light emitting unit(321), a light receiving unit(322), and a vibrator(325). The light emitting unit emits the light when the power is applied. The light receiving unit measures the light generated in the light emitting unit. The light receiving unit controls the current flowing on the coil by changing the resistance according to an amount of the light. The vibrator moves up and down by a spring according to the magnetization of the coil. The vibrator blocks the flow of the light generated in the light emitting unit.

Description

Vehicle horn control device {Apparatus for Controlling Automotive Horn}

The present invention relates to a vehicle horn control device.

In the related art, when the driver turns on the horn switch S attached to the horn 1 as shown in FIGS. 1 and 2, the current of the battery is caused by the magnetic flux generated in the coil of the core 2 through the contact. The armature (5) assembled with the vibration plate (3) and (3) is attracted, and the armature (5) descending by the suction force is configured to generate a beep through repeated motions of pressing the contact spring (6). .

At this time, a small amount of gas generated at the electrode of the contact when the horn switch (s) on or off is discharged to the outside through the drain hole (12) formed in the body (1) of the horn 1 while the drain hole ( Through 12) fresh air is introduced.

However, in the related art, the function of the product due to foreign matter such as moisture or dust through the drain hole 12 formed so that a small amount of gas discharge and air generated when the current is energized and interrupted in the body 10 of the horn 1 is introduced. There was this marred issue.

In addition, the electrode of the contact exposed in the atmosphere is corroded by the oxidation phenomenon may cause the malfunction of the horn.

The present invention provides a vehicle horn control device that replaces the function of the existing horn internal contact portion.

The present invention includes a coil power supply unit connected to one end of a coil wound around a core in a horn to supply power, and a power supply control unit controlling a current flow of the power supply control unit by performing a switching operation when power is applied. It provides a vehicle horn control device characterized in that.

As described above, according to the present invention, by providing a vehicle horn control device that replaces the function of the existing horn internal contact portion, it is possible to solve the contact operation failure of the horn caused by foreign substances, and to reduce the quality of the product due to contact wear. It is effective to prevent.

In addition, since the vehicle horn control device is housed in a relay box, when a problem such as a poor contact occurs, only the vehicle horn control device can be replaced without having to replace the entire horn, thereby making it easy to repair the horn. Can be done.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

Example

3 is a view showing the interior of the vehicle horn control device according to a preferred embodiment of the present invention.

Referring to FIG. 3, the vehicle horn control device 300 according to the present invention may be connected to one end of a coil 212 wound around a core 211 in the horn 200 to supply power to the coil power supply 310 and When the power is applied to the power supply control unit 320 to perform a switching operation to control the current flow of the power supply control unit 310. Here, the vehicle horn control device 300 is accommodated in the relay box (400) as shown in Figure 4 can be easily removed in the case of contact failure, it is easy to replace parts.

Coil power supply 310 according to the present invention is preferably made of a transistor 311, the power supply control unit 320 is connected to the base end of the transistor 311, the power is turned on and off, the large capacity power The horn 200 is supplied.

The power supply control unit 320 according to the present invention measures the light emitted from the light emitting unit 321 and the light emitting unit 321 for generating light when power is applied, and the magnitude of the resistance is changed according to the amount of incoming light The light receiving unit 322 for controlling the flow of current flowing through the coil 323, the vibrator vertically moves by the spring 324 according to the magnetization of the coil 323, and blocks the flow of light generated by the light emitting unit 321 325.

The operating principle of the vehicle horn control device 300 according to the present invention is as follows.

When the driver presses the horn switch 330 to supply power, the power is applied to the light emitting unit 321, the light receiving unit 322, and the coil 323. When the power is applied to the coil 323, the coil 323 is applied. Silver becomes an electromagnet and pulls the vibrator 325, which causes the vibrator 325 to move downward. The light emitter 321 inside generates light by receiving power, and the light receiver 322 measures the light. The light receiving unit 322 is changed in resistance according to the amount of incoming light, and when the vibrator 325 is lowered by the coil 323 to block the light of the light emitting unit 321 to increase the resistance of the light receiving unit 322. This prevents current from flowing in the coil. As a result, the coil 323 loses the electromagnetic force, and thus is lifted up again by the spring 324. By repeating this operation, the same function as the contacts in the existing horn is performed. The coil power supply 310 supplies a large amount of power to the horn 200 as power is turned on and off at the base end of the transistor 311 by the power supply control unit 320. In other words, the transistor 311 performs an on-off switching function. The horn 200 is shaken by the power supplied in this way to make a sound.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.
