Embodiment.
FIG. 1 is a front view of a display device provided with a device housing according to an embodiment of the present invention, FIG. 2 is a perspective view of the display device as viewed from the rear side, and FIG. 3 is a perspective view of the display device from the upper surface side. FIG. 4 is a cross-sectional view taken along the line IV-IV of FIG.

FIG. 1 shows an instrument panel 201 provided in the vehicle interior of a vehicle such as an automobile, and a display device 200 is provided in the center of the instrument panel 201. The display device 200 includes a display unit 100 and a device housing 110.

The display unit 100 is a display for integrating operations on in-vehicle devices such as a car navigation device, a car audio device, and a car air conditioner device. On the display unit 100, for example, a navigation screen by a car navigation device (a screen that displays the current location and traveling direction of the vehicle by superimposing it on a road map of the surrounding area), a TV screen by an audio controller, a user inputting and setting various instructions, and the like. A selection screen for performing, various messages, etc. are displayed. On the surface of the display unit 100, for example, a touch panel for inputting and setting various instructions by the user is provided. The display of the display unit 100 is controlled by, for example, a display drawing board (not shown).

A controller that controls, for example, a car navigation device, a car audio device, a car air conditioner device, or the like is connected to the display drawing board. Car audio equipment includes radios and televisions. The display drawing board is provided inside the device housing 110 shown in FIG. 2, for example.

The device housing 110 is provided on the back side (plus Z-axis direction side) of the display unit 100. On the upper surface 11a of the device housing 110, for example, a hole 110b for discharging the heat generated by the device provided inside the device housing 110 to the outside of the device housing 110 is formed.

The hole 110b is located, for example, at a position at the center of the upper surface 11a of the device housing 110 in the X-axis direction at a certain distance (for example, about 10 mm to 30 mm) from the back surface (the surface on the plus Z-axis direction side) of the display unit 100. It is a quadrangular opening that is formed. The shape of the hole 110b is not limited to a square shape, and may be an ellipse or the like.

A back cover 202 is provided on the upper side (plus Y-axis direction side) of the device housing 110. The back cover 202 covers the upper surface 110a of the device housing 110, and together with the instrument panel 201, constitutes a design portion at the front portion of the vehicle interior.

The gap 203 is formed with the back cover 202 of the device housing 110 provided. The gap 203 is formed between the back surface of the display unit 100 and the front surface of the back cover 202 (the surface on the minus Z-axis direction side), and the upper surface 110a of the device housing 110 and the lower surface of the back cover 202 (minus Y). It is formed between the surface on the axial side).

When a drink holder is provided on the upper part of the display device 200 or the like, when a container such as a PET bottle inserted in the drink holder condenses, water droplets generated on the surface of the container are transmitted to the back cover 202 and fill the gap 203. There is a risk of intrusion. If the water that has entered the gap 203 enters the hole 110b of the device housing 110, the internal device of the device housing 110 may break down.

The display device 200 according to the present embodiment includes ribs 11 in order to prevent water that has entered the gap 203 from entering the holes 110b of the device housing 110.

The rib 11 is composed of a first rib 111 and a second rib 112 provided on the upper surface 110a of the device housing 110 so as to block the virtual line-of-sight GL connecting the display unit 100 and the hole 110b. The line-of-sight line GL is equal to a virtual line connecting the display unit 100 and the hole 110b.

The first rib 111 extends from the upper surface 110a of the device housing 110 toward the upper side of the device housing 110 by a certain distance (for example, about 1 mm to 10 mm), and the end surface of the upper surface 11a of the device housing 110 in the minus X-axis direction. A band-shaped protrusion extending linearly from the surface toward the end surface of the upper surface 11a of the device housing 110 in the plus X-axis direction.

By providing the first rib 111, a groove 113 is formed on the upper surface 110a of the device housing 110. The groove 113 is a recessed space formed by being surrounded by the first rib 111, the upper surface 110a of the device housing 110, and the back surface of the display unit 100. The groove 113 extends in the X-axis direction in parallel with the first rib 111.

FIG. 5 is a first diagram showing the direction in which the water that has entered the groove 113 flows, and FIG. 6 is a second diagram showing the direction in which the water that has entered the groove 113 flows. W indicated by a solid arrow represents water that has infiltrated through the gap 203 and is captured in the groove 113. The water captured in the groove 113 is guided in the X-axis direction, reaches the side surface of the device housing 110, travels along the side surface of the device housing 110, and is guided to the lower side of the device housing 110.

The upper surface 110a of the device housing 110 may be a plane parallel to the XZ plane, or the device housing 110 is directed from the center of the device housing 110 in the X-axis direction toward the side surface of the device housing 110 in the X-axis direction. It may be a curved shape that curves downward (in the minus Y-axis direction) of 110. By forming the upper surface 110a of the device housing 110 into a curved shape in this way, the drainage of the water trapped in the groove 113 is improved, and the infiltration of water into the hole 110b is further suppressed.

The second rib 112 is composed of two protrusions 112a and 112b arranged apart from each other in the X-axis direction so as to straddle the hole 110b. The two protrusions 112a and 112b each extend a certain distance from the first rib 111 in the plus Z-axis direction. The heights of the two protrusions 112a and 112b in the plus Y-axis direction may be, for example, the same as the height of the first rib 111, or may be larger than the height of the first rib 111.

By providing the second rib 112, for example, even if the water captured in the groove 113 overflows from the groove 113 due to the vibration or centrifugal force of the vehicle, the second rib 112 functions as a water stop plate, so that the hole 110b The ingress of water into the water is prevented.

In the present embodiment, as the device housing 110 to which the rib 11 is applied, the display device 200 provided in a vehicle such as an automobile is taken as an example, but the device housing 110 to which the rib 11 is applied is , Not limited to this, it can also be applied to vehicles other than automobiles.

As described above, the device housing 110 according to the present embodiment is a device housing 110 provided on the back side of the display unit 100, and is provided on the upper surface 110a of the device housing 110 from the back surface of the display unit 100. It is provided between the display unit 100 and the hole 110b so as to block the virtual line-of-sight GL connecting the hole 110b formed at a certain distance and the display unit 100 and the hole 110b, and also in the device housing. A rib 11 extending upward from the upper surface 110a of the device housing 110 is provided. By providing the rib 11 on the upper surface 110a of the device housing 110, a groove 113 surrounded by the rib 11, the upper surface 110a of the device housing 110, and the back surface of the display unit 100 is formed, so that the groove 113 is formed from the upper part of the device housing 110. The infiltrated water is trapped in the groove 113, and the intrusion of water into the hole 110b formed in the upper surface 110a of the equipment housing 110 can be prevented.

The configuration shown in the above-described embodiment shows an example of the content of the present invention, can be combined with another known technique, and is one of the configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
