JP3072535U - Reinforcement structure for portable electronic devices - Google Patents

Abstract

(57) [Summary] A display surface of a portable electronic device is made of glass, so that when a shock is applied, the display surface is easily broken and the device cannot be used. A concave rib is provided at a position particularly near a display surface in a device, and small pieces of metal bodies of various shapes are embedded in the concave groove so as to have sufficient strength against impact and load. .

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a reinforcing structure for a portable electronic device having a small and thin body.

[0002]

[Prior art]

 For example, the housing of a portable electronic device such as an electronic dictionary may be unexpectedly fragile and damaged by a drop impact or a load from above. In particular, the LCD display is broken by glass and the display becomes invisible.

[0003]

[Problems to be solved by the invention]

 For this reason, measures to prevent damage to the equipment such as forming the housing thicker, increasing the number of reinforcing ribs, changing the material of the body from plastic to metal, and providing a lid on the LCD display unit Is considered.

[0004] However, absolute requirements for this type of portable electronic device to be small, lightweight, and thin on the body are required. Therefore, even if the thickness of the housing is increased or the material is changed and reinforced as described above, the weight increases and the thickness of the device increases, which is a cause of unpopularity.

[0005]

[Means for Solving the Problems]

 In view of this point, the inventor of the present invention has arrived at the present invention as a result of intensive prototyping research. The metal body is inserted to reinforce the housing.

[0006]

[Embodiment of the invention]

 The present invention will be described with reference to the accompanying drawings. FIGS. 1 and 2 show a reinforcement structure of a portable electronic device of the present invention, and FIG. 1 is a structural diagram of an electronic dictionary as an example. In the case of this electronic dictionary, one reinforcing rib (1) is provided on the side surface of the LCD display unit.

FIG. 2 is a sectional view taken along line XX of FIG. 1. As can be understood from FIG. 2, the reinforcing rib (1) is a groove having a concave cross section. Various metal bodies or composites as shown in FIGS. 3 and 4 are inserted and arranged.

[0008]

【Example】

 FIG. 1 is a plan view showing the internal structure of the electronic dictionary. An LCD display is provided above the electronic dictionary, and the table is usually covered with a glass plate.

This type of device A is entirely made of plastic and has one or several ribs (1) for reinforcement inside. However, as shown in a test example described later, impact or load In the present invention, the rib (1) is formed into a concave shape, and the metal body (2) is inserted into the groove to further reinforce the rib. FIG. 2 is a sectional view showing the relationship between the rib (1) and the metal body (2) of the device A, and FIG. 2 is a sectional view taken along line XX of FIG.

FIG. 3 is a view showing an example of a long metal body (2) to be inserted into the concave groove (1). The rod-like body and the linear body are simple as shown in FIG. Although the illustration is omitted because of the shape, in Fig. 3, the A diagram is T-shaped, the B diagram is an H shape, the C diagram is a square, the 2 diagram is a polygon, the E diagram is an L shape, the F diagram is a beaded flat plate, and the G diagram. A metal body (2) having various cross-sectional shapes can be inserted as a reinforcing material so as to have a U-shape.

FIG. 4 shows a means for inserting the metal body (2) in the case where the width of the concave groove (1) is widened, and a synthetic resin plate for filling a gap with the metal body (2). Insert a non-metallic spacer (3). In the figure, the figure A uses a T-shaped metal body (2), the figure B uses an L-shaped metal body (2), and the figure C uses a plate-shaped metal body (1). 2), and FIG. 2 shows a plate-shaped metal body (1) with spacers (3) inserted on both sides.

FIG. 4 shows an embodiment in which a U-shaped metal body (2) is inserted so as to straddle between two grooves (1) and (1). FIG. 3 is an embodiment view in which a metal plate (1) is arranged in a wave form in a groove (1). It can exert strength against external force. Note that reference numeral (4) in the drawing denotes a forming boss for maintaining the formation of the waveform.

FIG. 5 is a diagram showing an example of a load test, in which a load is applied to the LCD display unit from above from the device A. FIG. 6 shows a conventional product, in which the body was deformed and the glass was broken under a load of about 45 kgf. FIG. 7 shows the product of the present invention. Even when a load of 90 kgf is applied, the casing is not deformed (using the case of FIG. 2), and the glass is not damaged.

[0014]

[Effect of the invention]

 As described above, according to the present invention, it is possible to provide a rugged electronic device that is not easily damaged by a drop impact or accidentally stepped on a portable electronic device having a light weight and a thin body.
