Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heater indicator lamp for a vehicle, that is, an indicator lamp mounted on a vehicle to indicate control of cooling and heating.

This type of device is installed in front of the driver's seat in the passenger compartment and is used to check the status of the heater control in the passenger compartment. The controller is equipped with a control lever a that serves as an operating section, and the amount controlled by the lever a is indicated by the letters ``COOL'' and ``WARM'' attached to the panel b, and the accompanying wide part indicates that the amount controlled by the lever a is large. The configuration is such that the operator can know which position the knob f of the lever a is located on the elongated triangular indicator parts c and d shown.

The indicator C indicating cooling (COOL) is usually a blue part,
The indicator that indicates heating is usually a red section d, and is designed to indicate cold and warm colors respectively. It is designed to glow when light passes through it.

Therefore, the amount of air-conditioning control is performed by moving the knob f of the control lever a in the direction of the arrow g, but the display on the indicators c and d of the display panel b is independent of the amount of movement of the knob f, that is, the amount of air-conditioning control. , red indicator C9, and blue indicator d are always constant and bright.

The control amount can be determined by looking at the position of the knob f on the indicating portions c and d.

Therefore, in this type of conventional device, the amount of air conditioning control is determined based on how much the knob f deviates from the reference point, so it cannot be determined unless the knob f and the reference point are found at the same time. It is something.

However, in the conventional example, the reference point and the position of the knob f are not clearly defined, and the display on the indicators c and d does not change according to the control amount, so it is difficult to determine the degree of control. It is difficult to judge whether this is the case.

Moreover, the entire indicator parts c and d are always illuminated, but this can cause dazzling light, and considering the safety of driving, it is desirable to be able to clearly judge the control amount with as little light as possible. Contrary.

In view of the above circumstances, the present invention is designed to allow the current heater control amount to be visually confirmed at a glance, to make an intuitive judgment easily and immediately, and to display the heater control amount on the indicator. To provide a heater control indicator lamp for a vehicle, which allows the user to know the amount just by looking at it, has a light emitting part of the display part as small as possible, makes it easy to recognize the control amount, and improves safety during driving. The purpose is to

An example of implementing the present invention will be described below with reference to the drawings.

The illustrated example is an application of the present invention to an automobile heater control indicator lamp disposed in the interior of an automobile.

In other words, if the car is equipped with an air conditioning system,
Generally, a lamp is installed on the dash board to adjust the air conditioning and heating and display the degree of adjustment, so this example applies the present invention here.

FIG. 2 shows this example, and as illustrated in the figure,
The heater control indicator lamp of the present invention includes an operating section 1 that controls cooling/heating, and a display section 2 that indicates the status of the heater control performed by the operating section 1. A plurality of light emitting elements 21a.

22 a...; 21b, 22b..., of which the light emitting elements 21a, 2 are located next to the air conditioner display.
2a... and the light emitting elements 21b and 2 next to the heating display
2b... The light emitting element 20 at the reference position, where neither cooling nor heating is performed, is always lit, and depending on the status of the heater control on the operation unit 1, the light emitting element 20 is in a different color from the one in which cooling or heating is performed. The present invention is characterized in that one light emitting element is turned on, and the control amount is displayed based on the distance between the lighting section and the lighting section 20 at the reference position.

The operating section 1 of this example is a lever as shown in the figure, and the tip thereof is a knob 11.

This is moved from side to side along the length of the display section 2 at the lower part of the display section 2 in the direction of arrow A, thereby adjusting the heater.

The display section 2 of this example is installed in a row on a display panel 3 arranged on a dash board section of a vehicle interior.

As the light emitting element, an LED (light emitting diode) was used.

On the display panel 3, C00L indicates cooling and heating, respectively, corresponding to the display section 2.

The characters WARM are formed, and the display section 2 is arranged in a line between the two.

This C00L. Make the word WARM shine dimly,
In order to be visible even at night, the display panel 3 is configured to be illuminated by a lamp 4 from the back side.

As mentioned above, the display section 2 includes a light emitting element 21a next to the air conditioner display.
, 22a... and the light emitting element 21b next to the heating display.
, 22b, etc. are configured in different colors, but in this example, the cooling display is green (or blue), and the heating display is red, which are cool and warm colors, respectively, to make it easier to judge. .

The neutral point where neither air conditioning nor heating is activated is the reference position, and the light emitting element 20 at that position is always lit. In this example, this element 20 is yellow, and it is set at the center, that is, the cooling display and heating display. Place it between the screen and the display.

To set the emitted light color of each light emitting element, it is possible to use light emitting elements of each color (that is, LEDs in this example), or to set a blue (green) or red light transmitting part on the display panel 3. It may be formed by silk printing or the like, and the light emitting element may be placed on the back side.

Furthermore, a color filter may be placed in front of the light emitting element.

The display section 2 is configured to light up one of the light emitting elements of the cooling or heating section in accordance with the status of the heater control of the operation section 1. In this example, this is done as follows. They are distantly related with a similar structure.

That is, as shown in FIG. 3, the lever-shaped operating section 1
The movable contact 5 is fixed in the middle of the light emitting elements 21a,
Fixed contacts 61a and 62a connected to 22a...; 21b and 22b...;
61b, 62b, . . . are arranged in parallel, and the movable contact 5 is arranged so as to slide on the fixed contact and connect to one of them.

If the positive side of the power source (indicated by Vcc in the figure) is connected to the movable contact 5 and the terminal opposite to the fixed contact of each light emitting element is grounded, the movable contact 5 moves in conjunction with the operation unit 1. Only the light-emitting element corresponding to the fixed contact that is in contact with the light-emitting element will light up.

Therefore, the light emitting element at the position corresponding to the amount of heater control I/roll on the operation unit 1 is lit.

On the other hand, a positive power supply is always connected to the contact point 60 of the light emitting element 20 at the reference position, so that it is always lit.

In the figure, r is a protection resistance.

With the above configuration, the light emitting element 20 is always lit at the neutral point, indicating the reference point which is the zero point where neither cooling nor heating is performed.

When the operating part 1 is operated and moved from the neutral position, the movable contact 5 sequentially moves to the fixed contact 6 as the operating part 1 moves.
1a, 62b...; 61b, 62b...
・It moves over the top and contacts the corresponding fixed contact to light up the light emitting element connected to it.

Even if it is turned on once, the light goes out when the operation part 1 moves and the contact is broken, so only the light emitting element corresponding to the final position of the operation part 1 is turned on.

By comparing this light emission and the lighting of the light emitting element 20 at the reference position, which is always lit, the status of the heater control can be known at a glance by comparing the positions of the two.

In addition, since the lighting location of the light emitting element moves in response to changes in the control amount, the operator can visually perceive the status of his/her operation as a moving light spot, resulting in excellent operability.

Furthermore, since the cooling and heating channels are constructed in a unique manner, the distinction between which control is being made can be clearly recognized, and such operations can be prevented, and even if an operation is made incorrectly, it can be corrected immediately. It is.

In the above example, as shown again in FIG. 4, the light emitting element 20 indicating the neutral reference position is in the yellow part Y, the cooling part is in the cold color part G of green (or blue, etc.), and the heating part is in the cold color part G. Since the red warm color part R is used, there is yellow light emission and then there is light emission from either the cooling or heating side, so the recognition is very clear and the judgment is easy.

As shown in FIG. 5, it is advantageous to add numbers to the cooling section G and the heating section R to indicate the degree of heater control, since the amount of operation can be more clearly understood digitally.

In other words, you can tell whether the air conditioner is cooling or heating by the color, and the intensity by the number.

Further, the operation section 1 may be formed in a dial type.

In this case, it is easy to determine if the display section 2 is also arranged in a ring shape surrounding the dial.

It is also possible to use numbers as shown in FIG.

No matter which configuration is adopted, in the present invention, there is only one moving light spot, and only two spots at the maximum are lit, including the light emitting element 20 at the neutral point.

Therefore, since the light emission is suppressed to a minimum, there is no extra light that may cause dazzle, which is desirable from the viewpoint of safe driving.

It is also preferable in terms of design.

Furthermore, with the present invention, the amount of control could not be determined without visually detecting the deviation between the knob and the reference point, whereas with the present invention two points are illuminated on the - line (or - arc), making it easy to judge the amount of control. You can also know the status of the heater control with certainty.
This has the advantage of allowing quick confirmation.

As detailed above, the present invention is a heater indicator lamp for a vehicle, which includes an operation section for controlling cooling/heating, and an instruction section for indicating the status of the control by the operation section. The light-emitting element next to the cooling display and the light-emitting element next to the heating display are of different colors, and the light-emitting element in the reference position where neither cooling nor heating is performed is always lit, and the light-emitting element next to the heating display is always lit. It is characterized by a structure that lights up one light emitting element of the cooling or heating side depending on the status of the heater control, so you can see the current status of the heater control at a glance just by looking at the display. The amount of operation can be visually recognized, making intuitive judgments easy and quick, and since the number of light-emitting parts is minimal, driving safety is also high.

It should be noted that, as a matter of course, the present invention is not limited to the embodiments illustrated and described above.
