Description

The present disclosure relates to a display device mounted on a vehicle.

As described in Patent Document 1, in a display device including a meter or the like mounted on a vehicle, a mounting member for performing decoration or the like is provided on a translucent plate-shaped member covering the meter or the like. There is.

Japanese Unexamined Patent Publication No. 2017-181610

Here, in the display device, in order to improve the visibility of the meter or the like, the plate-shaped member may be subjected to a process of suppressing the reflection of visible light incident on the plate-shaped member. As an example of such processing, in the display device described in Patent Document 1, a low-reflection layer such as an AR film is provided on the plate-shaped member.

However, even if such a low reflection layer is provided, the plate-shaped member may not be able to completely suppress the reflection of visible light. As a result, the visible light is reflected by the plate-shaped member, so that the occupant can recognize the presence of the plate-shaped member, which may impair the aesthetic appearance of the display device.

One aspect of the present disclosure provides a technique capable of improving the aesthetics of a display device.

One aspect of the present disclosure is a display device (1) mounted on a vehicle, which includes a display unit (3), a plate-shaped member (4), and a decorative unit (5, 50). The display unit is arranged toward the passenger compartment. The plate-shaped member is a transparent member arranged so as to cover the display portion. The decorative portion is attached to the plate-shaped member. The reflectance of the plate-shaped member with respect to visible light is 0.4% or less. The decorative portion is attached to the plate-shaped member so that at least a part of the decorative portion is separated from the edge portion of the plate-shaped member.

According to such a configuration, the reflection of visible light on the plate-shaped member is suppressed, and the existence of the plate-shaped member is difficult to be visually recognized by the occupant. As a result, a visual effect can be produced in which the decorative portion on the plate-shaped member appears to float in the air. Therefore, the aesthetic appearance of the display device can be improved.

In addition, the reference numerals in parentheses described in this column and the scope of claims indicate the correspondence with the specific means described in the embodiment described later as one embodiment, and limit the technical scope of the present disclosure. It is not something to do.

It is a schematic front view of the display device. FIG. 2 is a cross-sectional view taken along the line II-II of FIG. It is the schematic which shows the decorative part attached to the plate-shaped member.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
[1. composition]
The display device 1 shown in FIG. 1 is mounted on a vehicle. Hereinafter, the vehicle equipped with the display device 1 will be referred to as the own vehicle. In addition, the person who gets on the own vehicle is the occupant. The display device 1 is provided on the instrument panel of the own vehicle as an example. The display device 1 may be provided near the center of the instrument panel, or may be provided in front of the occupant (for example, the driver).

The display device 1 includes a panel unit 2, a display unit 3, a plate-shaped member 4, and a decorative unit 5 (see FIGS. 1 and 2). As an example, the display device 1 may include three display units 3. However, the number of display units 3 in the display device 1 is not particularly limited.

In the following description, the left-right direction, the up-down direction, and the front-back direction of the own vehicle are simply described as the left-right direction, the up-down direction, and the front-back direction.
The panel unit 2 is arranged inside the display device 1 so as to face the vehicle interior space (hereinafter referred to as the vehicle interior) of the own vehicle.

The display unit 3 may be configured as an instrument that indicates the state of the own vehicle, such as the speed of the own vehicle and the remaining amount of fuel. The display unit 3 is configured as, for example, an analog meter provided with a rotating pointer 30. The display unit 3 displays the state of the own vehicle by rotating the pointer 30 to indicate a value indicating the state of the own vehicle. The display unit 3 may display the state of the own vehicle by, for example, a liquid crystal screen or an LED instead of the analog meter.

The display unit 3 is provided on the panel unit 2. Further, the display unit 3 is arranged toward the vehicle interior so that the occupant can visually recognize the display by the display unit 3.
The plate-shaped member 4 is a transparent member. The transparency of the plate-shaped member 4 may be lowered by treating the plate-shaped member 4 for the purpose of decoration or the like. The plate-shaped member 4 is formed of transparent glass as an example. However, a material (for example, resin) that has heat resistance during manufacturing of the plate-shaped member 4 and the display device 1 (for example, heat resistance to a temperature of 200 ° C. or higher) and durability when the display device 1 is used. ), The plate-shaped member 4 can be formed using the material.

The plate-shaped member 4 includes a main body portion 40 and a mounting portion 41.
The main body 40 is a plate-shaped portion that extends substantially in a plane. The main body 40 is arranged so as to cover the display 3. Specifically, the main body 40 is arranged so that the display 3 exists between the main body 40 and the panel 2. The main body 40 faces the passenger compartment. Here, the surface of the main body 40 arranged on the vehicle interior side is referred to as the first surface 42, and the surface on the opposite side thereof is referred to as the second surface 43.

Further, thereafter, in the main body portion 40, a portion including the outer edge of the main body portion 40 and the band-shaped region extending along the outer edge of the main body portion 40 on the first surface 42 and the second surface 43 is defined as an edge portion. .. The edge of the first surface 42 may be covered with, for example, clusters 6 constituting the dashboard of the own vehicle. Of course, it is assumed that the plate-shaped member 4 is arranged with the outer edge of the main body 40 exposed without covering the edge portion. In such a case, the outer edge of the main body 40 may be used as the edge on the first surface 42.

The main body 40 and the panel 2 may be arranged in parallel with each other, or may be slightly tilted with respect to the panel 2 so that the main body 40 faces upward or downward. As an example, the main body 40 may be tilted by about 5 ° with respect to the panel 2 so that the upper edge of the main body 40 is located closer to the passenger compartment than the lower edge.

The mounting portion 41 is one or a plurality of wall-shaped portions protruding from the outer edge of the main body portion 40.
When the plate-shaped member 4 is arranged, the mounting portion 41 may be mounted on the panel portion 2. That is, the plate-shaped member 4 may be engaged with the outer edge of the panel portion 2 via the mounting portion 41.

The plate-shaped member 4 is subjected to a low reflection treatment for visible light. Specifically, the first surface 42 and the second surface 43 of the main body 40 are subjected to a low reflection treatment by an AR (anti-reflection) coating. The AR coating treatment can be performed by various methods (for example, sputtering, vapor deposition, or dip coating). It should be noted that the treatment may be repeatedly applied to the plate-shaped member 4 to form a multi-layer AR coat on the plate-shaped member 4. Then, the number of times of the processing may be, for example, an arbitrary number of predetermined times between 2 times and 20 times. By performing such a treatment, the reflectance of the plate-shaped member 4 with respect to visible light is adjusted to 0.4% or less, preferably 0.1% or less.

The first surface 42 and the second surface 43 may be subjected to another low reflection treatment instead of the AR coating treatment. The other low reflection treatment may be, for example, AG (anti-glare) treatment, AF (anti-finger) treatment, or moth-eye treatment. However, it is preferable that the first surface 42 is subjected to AR coating treatment.

The decorative portions 5, 50 are attached to the first surface 42 of the main body portion 40 (see FIGS. 1 to 3). The decorative portions 5, 50 may contain, for example, metal or resin, or may be configured as a paint printed on the first surface 42.

Further, the decoration portions 5, 50 are attached to the first surface 42 so that at least a part of the decoration portions 5, 50 is separated from the edge portion of the main body portion 40. In other words, the decorative portions 5, 50 are attached to the first surface 42 in a state where at least a part of the decorative portions 5, 50 does not contact the edge portion. In the present embodiment, as an example, the decorative portions 5, 50 are attached to the first surface 42 in a state where all of the decorative portions 5, 50 do not come into contact with the edges. That is, the decoration portions 5, 50 are attached to the first surface 42 in a state where all of the decoration portions 5, 50 do not come into contact with the cluster 6 covering the edge portion on the first surface 42. The decorative portions 5, 50 may be attached to the first surface 42 in a state where a part of the decorative portions 5, 50 is in contact with the cluster 6.

As an example, the decorative portions 5, 50 are provided along the outer edge of the display area A so as to surround the display area A. The display area A refers to an area in front of the display unit 3 on the first surface 42 of the main body unit 40. Therefore, when the occupant looks at the first surface 42 of the main body 40 from the front of the display 3, the display 3 is visually recognized as being located inside the decorations 5, 50.

Specifically, the decorative portion 5 may be an elongated member extending along the outer edge of the display area A. That is, the decorative portion 5 may be configured as a frame-shaped member that orbits along the outer edge of the display area A. More specifically, the decorative portion 5 may be configured as a ring-shaped member. As an example, the decorative portion 5 of FIG. 1 is configured as a metal ring-shaped member. In addition to this, the decorative portion 5 may be configured as an elliptical or polygonal frame-shaped member, or may be a C-shaped member.

In addition to this, the decorative portion 50 may include a plurality of portions arranged side by side along the outer edge of the display area A. Specifically, for example, as shown in FIG. 3, a plurality of rectangular portions formed as paint included in the decorative portion 50 are extended toward the outside of the display area A, and the display area A has a plurality of rectangular portions. They may be arranged side by side along the outer edge. Further, for example, a plurality of elongated portions constituting the decorative portion 50 may be arranged in a state of extending along the outer edge of the display area A.

The decorative portion 5 may be attached to the first surface 42 of the main body portion 40 with an adhesive. Further, a groove may be formed on the first surface 42, and the decorative portion 5 may be attached to the groove.
[3. effect]
According to the embodiment described in detail above, the following effects are obtained.

(3a) In the display device 1, the decorative portions 5, 50 are mounted on the first surface 42 of the plate-shaped member 4 so that at least a part of the decorative portions 5, 50 is separated from the edge portion of the plate-shaped member 4. It is attached. Then, the reflectance of the plate-shaped member 4 in the display device 1 with respect to visible light is adjusted to 0.4% or less, preferably 0.1% or less. Therefore, the reflection of visible light on the plate-shaped member 4 is suppressed, and the presence of the plate-shaped member 4 is difficult to be visually recognized by the occupant. As a result, a visual effect can be produced in which the decorative portions 5, 50 on the plate-shaped member 4 appear to float in the air. Thereby, the aesthetic appearance of the display device 1 can be improved.

Here, when the reflectance of the plate-shaped member with respect to visible light is high, it may be difficult for the occupant to visually recognize the display unit depending on the direction in which the visible light is reflected. Therefore, it is necessary to adjust the direction in which visible light is reflected in the plate-shaped member. Specifically, it is necessary to adjust the inclination of the plate-shaped member with respect to the panel portion or to bend the plate-shaped member so that visible light is reflected toward the cluster or the steering column. Therefore, the space between the plate-shaped member and the panel portion increases, and the display device may become large. Further, by providing the cluster around the display device, the aesthetic appearance around the display device may be impaired.

However, in the display device 1, since the reflection of visible light on the plate-shaped member 4 is suppressed, it may not be necessary to adjust the direction of reflection of the visible light. Therefore, in the display device 1, a plate-shaped member that spreads substantially in a plane and is arranged in parallel with the panel portion can be used. As a result, the space between the plate-shaped member 4 and the panel portion 2 can be reduced, and the display device 1 becomes compact. Further, since the reflection of visible light on the plate-shaped member 4 is suppressed, the members around the display device 1 can be configured without considering the direction in which the visible light is reflected on the plate-shaped member 4.

(3b) Further, in the display device 1, the decoration portions 5, 50 are arranged so that all of the decoration portions 5, 50 are separated from the edge portion of the plate-shaped member 4 and the cluster 6, or the decoration portion 550. A part of 5, 50 is attached to the first surface 42 of the plate-shaped member 4 in a state of being in contact with the edge portion and the cluster 6. Therefore, a visual effect can be produced in which the decorative portions 5, 50 on the plate-shaped member 4 appear to float in the air. Thereby, the aesthetic appearance of the display device 1 can be improved.

(3c) Of the first surface 42 and the second surface 43 of the plate-shaped member 4 in the display device 1, at least the first surface 42 is subjected to AR coating treatment to reflect visible light on the plate-shaped member 4. The rate is adjusted. In the AR coating treatment, unlike the AG treatment or the moth-eye treatment, fine irregularities are not formed on the surface of the first surface 42, so even when the occupant touches the surface of the first surface 42 with a finger. The reflectance of the plate-shaped member 4 does not deteriorate due to fouling of the unevenness of the surface. As a result, the reflection of visible light can be suitably suppressed in the plate-shaped member 4.

(3d) The plate-shaped member 4 in the display device 1 is formed of transparent glass having heat resistance at the time of manufacturing the plate-shaped member 4 and the display device 1 and having durability at the time of using the display device 1. NS. Therefore, the display device 1 can be preferably manufactured and used.

(3e) The display unit 3 in the display device 1 is configured as an instrument that indicates the state of the vehicle. Further, the instrument is configured as an analog meter. Therefore, the state of the own vehicle can be preferably displayed.

Specifically, the decorative portions 5, 50 may be provided on the second surface 43 along the outer edge of the opposite region so as to surround the opposite region. The opposite region refers to an region on the second surface 43 of the main body 40 on the opposite side of the display region A. Therefore, when the occupant looks at the main body 40 from the front of the display 3, the display 3 is visually recognized as being located inside the decorations 5, 50 on the second surface 43. Regarding other configurations, the decorative portions 5, 50 may be attached to the second surface 43 in the same manner as when they are attached to the first surface 42.
