Abstract

PURPOSE: A seesaw button using a car is provided prevent a shade from being on both ends of the button while using one LED. CONSTITUTION: In a seesaw button using a car, a lighting-emitting unit(100) radiates light with the seesaw button. A sprit guide unit(200) of an Y-shape divides the light into more than two paths. The hemisphere of a concave shape is formed in the bottom of the Y shape. A saw tooth is formed at both sides of the Y-shape. The hemisphere of the concave type protects the lighting-emitting unit.

Description

Seesaw Button Using Car}

The present invention relates to a seesaw button for a vehicle, and more particularly to a seesaw button for use in a vehicle.

In general, the center facia in front of the vehicle interior has a navigation system equipped with an AV (Audio Video) system or a monitor that can provide geographical information or watch DMB (Digitial Multimedia Broadcasting) for the driver's convenience. Many electronic components will be installed.

Many operation buttons for operating the device are installed on the front panel of the AV system, and at this time, many seesaw buttons are mounted to improve the driver's convenience of operation or to increase the operation efficiency of the buttons.

The seesaw button is a button which is installed to enable the seesaw operation so that both sides can be alternately pressed. The seesaw button enables to easily operate functions opposite to each other such as an on / off function with a single button.

Hereinafter, a conventional seesaw button will be described with reference to FIGS. 1 and 2.

1 is a view for explaining a coupling relationship of a conventional seesaw button, Figure 2 is a view for explaining the structure of a conventional seesaw button.

As shown in FIG. 1, the conventional seesaw button includes a button portion 10, a housing 20, and a hinge portion 30. That is, in the conventional seesaw button, the button unit 10 and the housing 20 are combined to form a button shape, and the seesaw button having the button shape is assembled to the panel, for example, the PCB 40 by the hinge part 30.

The seesaw button assembled to the PCB 40 implements a function of operating two functions (for example, AM and FM) by a single key by vertical seesaw operation.

Such a seesaw button generally uses LED 50 as a light. As shown in FIG. 2, the LED 50 of 2EA may be used as an illumination of each letter, AM or FM, or the LED 50 of 1EA may be used as an illumination of each letter, AM and FM. In the former case, the power consumption is high because the 2EA's LED 50 must be used. In the latter case, since the 1EA's LED 50 is used, the power consumption can be reduced and the production cost can be lowered. There is a problem that occurs.

The present invention has been made in view of the above problems, and an object thereof is to provide a seesaw button for a vehicle which can prevent a shadow formed at both ends of a button while using one LED as a button light.

In order to achieve the above object, a vehicle seesaw button according to an aspect of the present invention includes a light emitting unit for emitting light by the illumination of the seesaw button; And a light distribution guide part configured to distribute light emitted from the light emitting part through two or more paths.

According to the present invention, it is possible to prevent the shading on both ends of the button while using one LED as the button illumination.

In particular, the number of LEDs used as button lighting can be reduced, thereby lowering the production cost.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms. It is provided to those skilled in the art to easily understand the scope of the invention, which is defined by the description of the claims. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. It is noted that " comprises, " or "comprising," as used herein, means the presence or absence of one or more other components, steps, operations, and / Do not exclude the addition.

Hereinafter, a vehicle seesaw button according to an embodiment of the present invention will be described with reference to FIGS. 3 to 5. 3 is a view for explaining the seesaw button for a vehicle according to an embodiment of the present invention, Figure 4 is a view for explaining the irradiation of the light distribution guide portion, Figure 5 is a view for explaining the shape of the light distribution guide portion.

As shown in FIG. 3, the vehicle seesaw button according to the exemplary embodiment of the present invention includes a light emitting unit 100 and a light distribution guide unit 200.

The light emitter 100 emits light by illumination of the seesaw button.

The light distribution guide part 200 is formed in a “Ｙ” shape and inserted into the housing 400, so that the light emitted from the light emitting part 100 is combined with the housing 400 as shown in FIG. 4. Evenly distribute to both sides of 300).

As shown in FIG. 5, the light distribution guide 200 has a concave hemisphere 210 formed on a bottom surface of a “Ｙ” shape, and serrations 220 are formed on both top surfaces of a “Ｙ” shape. Is formed.

The concave hemisphere 210 surrounds the light emitting unit 100 so that the emitted light is scattered and distributed to the light distribution guide unit 200.

The sawtooth 220 causes light scattered and scattered by the light distribution guide unit 200 to cause diffuse reflection and to be irradiated to the button 300 evenly.

As described above, the vehicle seesaw button of the present invention can prevent shading on both ends of the button while using one LED as the button lighting. Due to the shading problem, the use of two LEDs can be reduced to one, thereby lowering the production cost.

Although the configuration of the present invention has been described in detail with reference to the preferred embodiments and the accompanying drawings, this is only an example, and various modifications are possible within the scope without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.
