Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a three-dimensional impact detection display member. For example, the present invention relates to a three-dimensional impact detection display member capable of detecting and displaying whether an electronic device such as a mobile phone has received an impact such as a drop.

[0002]

2. Description of the Related Art In recent years, small electronic devices, especially portable electronic devices, have been widely used. When the portable type is used, it is considered that the number of failures due to impact such as dropping increases. On the other hand, the failure modes are roughly classified into two types: an inborn error caused by a failure of an electronic device or an electronic component itself, and an acquired mode caused by an impact of dropping the device. It is necessary to distinguish these failure modes from the viewpoint of product warranty and the like.

For this reason, electronic devices, especially mobile phones, PHs
For mobile communication devices such as S, portable electronic devices such as small personal computers, etc., there is a need for an inexpensive and small-sized detection display member that detects and displays an impact such as a drop to the extent of failure. I have.

Conventionally, an accelerometer for measuring acceleration has been used to detect an impact such as a fall. As this accelerometer, a sensor that senses acceleration up to a breaking limit and outputs it as an electric signal by an attached circuit is known.
(For example, JP-A-5-142243). This sensor is manufactured for the purpose of electrically measuring characteristics, and the measurement requires an external circuit and a power supply.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described. An embodiment of the three-dimensional impact detection display member of the present invention will be described with reference to FIGS. FIG. 1 is an explanatory diagram of a three-dimensional impact detection display member according to the first embodiment. FIG. 2 is an explanatory diagram of a portable electronic device to which the three-dimensional impact detection display member according to the second embodiment is attached.

Embodiment 1 will be described. As shown in FIG. 1, the three-dimensional impact detection display member 1 of this embodiment includes a case 2 serving as a case body and an ink ball 3 serving as a sealing body. The case 2 is made of a transparent or translucent glass material or resin material whose inner surface is frosted, and has a structure in which the ink ball 3 is built in and sealed. The ink ball 3 includes an outer shell 31 made of an opaque glass material, a resin material, or the like, and a red display ink 32 serving as an enclosed color forming material. In addition, as an example of the size of the three-dimensional impact detection display member 1, the minimum value of the size of the ink ball for detecting the coloring material adhered to the inner surface of the case upon receiving an impact is about 1 mm in diameter. The maximum value is about 5mm in diameter to be mounted on a mobile phone including the case. The size of the case for housing the ink ball is preferably a cube having a side of 3 to 7 mm.

The principle of inspection of the three-dimensional impact detection display member 1 according to the first embodiment will be described with reference to FIG. In addition,
(B), (d), (f), and (h) are cross-sectional views. In the normal state, as shown in FIGS. 1A and 1B, the ink ball 3 is in a state of falling down by gravity in the cavity of the case 2. Outer shell 3 that forms a container for display ink 32 of ink ball 3 (encloses a coloring material such as red ink).
Numeral 1 is made of an opaque (white or the like) glass material or resin material, and the display ink 32 inside cannot be seen. On the other hand, when the ink ball 3 falls, as shown in FIGS. 1C and 1D, the ink ball 3 falls on the inner surface 21 of the case by inertia while sticking to the surface opposite to the falling direction. Then, at the time of collision, as shown in FIGS. 1E and 1F, the outer shell 31 of the ink ball 3 is broken by the impact G of the collision, and as shown in FIGS. Since the sealed display ink 32 flows into the cavity of the case 2 and is colored, it can be easily detected visually. The frosted glass-like frosted surface of the inner surface of the case was not colored with the display ink 3 before being colored.
2 is slightly visible, but when colored, the display ink 3
2 looks better.

In the three-dimensional impact detecting and displaying member 1 of the first embodiment, since the outer surface of the ink ball 3 and the inner surface 21 of the case are both spherical, the ink ball 3 is always impacted in the falling direction regardless of the mounting posture. G will be received. Conversely, even if the product to which the member 1 is attached falls in any posture, the applied impact G can be detected, and a three-dimensional impact can be detected and displayed.

The setting of the impact G to be detected depends on the ink ball 3
The width can be easily set widely by the breaking strength of the outer shell 31. At this time, the case 2 is made common without changing, and by changing the strength by changing the material, thickness, shape, outer shape, etc. of the outer shell 31 of the ink ball, an arbitrary set value of the impact G can be easily set. . The combination of the case 2 and the ink ball 3 may be a case 2 made of a glass or resin material whose inner surface is made semi-permeable by frosty processing, and an outer shell 31 made of a transparent glass material or a resin material.

Embodiment 2 will be described. The electronic device of the present embodiment is a mobile phone, and includes a mobile phone main body 4 and a three-dimensional impact detection display member 1, as shown in FIG. The three-dimensional impact detection display member 1 is embedded in, for example, the bottom of the mobile phone main body 4. When the mobile phone falls, 3
The dimensional shock detection display member 1 can detect and display a shock by operating as described in paragraph 0012 and the like.

[0016]

According to the present invention, a detection circuit and a power supply are unnecessary, and furthermore, the impact such as a drop is detected without polluting the surroundings.
It can be displayed clearly. Also, downsizing,
The built-in space in a small electronic device can be reduced.
A dimensional impact detection display member can be obtained.
