DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable information processing apparatus such as a notebook personal computer, and more particularly, to a shock-resistant support structure of a built-in video display device.

[0002]

2. Description of the Related Art In recent years, portable information processing apparatuses such as notebook personal computers have been rapidly spreading. However, since the portable information processing device is intended to be used by the user while holding it in his hand or in his pocket and sometimes standing, the user may drop the portable information processing device. there's a possibility that. Recent portable information processing apparatuses often include a video display device as a display unit. Of the components of a portable information processing apparatus having such a video display device, the heaviest component is generally the video display device, and the most expensive and fragile component is also the video display device. Therefore,
There is a strong demand in the market for a portable information processing device that is hard to break even when a user drops and has excellent durability. [Explanation of FIG. 6] FIG. 6 shows a structure of a first conventional portable information processing apparatus. In the figure, reference numeral 1 denotes a housing, which is an injection molded product made of metal, resin, or the like. Reference numeral 21 denotes an L-shaped elastic structure made of metal. Reference numeral 3 denotes an image display device, for example, a liquid crystal module or a plasma display panel. Reference numeral 4 denotes a fastening member such as a screw or a rivet. The elastic structure 21 is fixed to the housing 1 by the fastening member 4.
Has been concluded. The image display device 3 is fastened to the elastic structure 21 by the fastening member 4.

[Explanation of FIG. 7] FIG. 7 shows a structure of a second conventional portable information processing apparatus. In the figure, reference numeral 1 denotes a housing, which is an injection molded product made of metal, resin, or the like. Reference numeral 25 denotes a buffer material such as gel or urethane. Reference numeral 3 denotes a video display device, for example, a liquid crystal module or a plasma display panel. The cushioning material 25 is arranged inside the housing 1 so as to surround the video display device 3. The image display device 3 and the cushioning material 25 are attached to each other with a double-sided tape or the like. The housing 1 and the cushioning material 25 are attached to each other with a double-sided tape or the like.

[0004]

Problems of the prior art will be described below. In the first conventional portable information processing apparatus,
When an impact is applied from the direction of the arrow 91, the impact is attenuated by the deformation of the elastic structure 21 and transmitted to the video display device 3, so that the possibility that the video display device 3 is damaged is reduced. However, when an impact is applied from the direction of the arrow 92, the elastic structure 2 is hardly deformed and the impact is transmitted directly to the video display device 3, so that the possibility that the video display device 3 is damaged increases. In addition, since the elastic structure 21 having the L-angle shape is attached to the housing 1 by using as many as fourteen screws 4, it is difficult to realize a portable information processing device that is easy to assemble at low cost. is there.

[0005] In the second portable information processing apparatus, the heat generated by the image display device may cause the buffer material 25 to deteriorate over time. By solving these problems, the structure that the image display device is unlikely to be damaged by impact,
To provide a portable information processing device having a structure that is easy to assemble at a low cost and a structure that does not have a risk of aging due to heat.
It is an object of the present invention.

[0006]

According to a first aspect of the present invention, there is provided a portable information processing apparatus in which a video display device is mounted using an elastic structure inside a housing, the portable information processing apparatus being fastened inside the housing. A portable information processing apparatus, wherein an image display device is supported in contact with an elastic structure.

[0007] The conventional portable information processing device hardly elastically responds to an impact from a specific direction depending on the structure in which the image display device is fastened to the elastic structure. For this reason, there is a problem that it is fragile with respect to the impact from the specific direction. In the portable information processing device of the present invention, the position of the image display device is regulated by a constant pressure by the pressurized elastic structure (the magnitude of the pressurization is arbitrary and includes zero). In a normal use state, it is placed at a fixed position in the portable information processing device. When a shock is applied to the portable information processing device, the elastic body absorbs the shock. The image display device is only swayed in the portable information processing device, and is less likely to be directly impacted. In addition, since the image display device is supported in contact with the elastic structure, the image display device and the elastic structure are displaced relative to each other by the elastic structure regardless of the direction in which the impact is applied. While absorbing the shock, the image display device swings in the portable information processing device. Therefore, the impact resistance of the portable information processing device of the present invention is less dependent on the direction in which the impact is applied. Accordingly, the present invention has an effect of providing a portable information processing apparatus having a structure in which the image display device is less likely to be damaged by an impact.

[0008] In the portable information processing apparatus of the present invention,
Since the image display device is supported in contact with the elastic structure, no screws are used for fixing the image display device to the elastic structure. Therefore, the portable information processing apparatus according to the present invention does not require the material cost of the screws, and does not require the trouble of fixing the image display device to the elastic structure with the screws. Accordingly, the present invention has an effect of providing a portable information processing device having a structure that is easy to assemble at low cost.

In the portable information processing apparatus of the second prior art, since the image display device is surrounded by the cushioning material, the heat generated by the image display device is liable to be trapped, causing an increase in the internal temperature or buffering due to the heat. There was a risk that the material would deteriorate over time. In the portable information processing device of the present invention, since the video display device is not surrounded by the cushioning material, the heat generated by the video display device is easily radiated to the outside. Further, unlike the second conventional example, since there is a wide selection range of the material of the elastic structure and the like, it is easy to select an elastic structure without fear of deterioration over time. In the present invention, for example, an organic material such as rubber or a metal material such as a leaf spring can be used. As a result, the present invention has an effect of providing a portable information processing device having a structure in which there is no fear of deterioration over time due to heat.

Also, a slide spring or a cylindrical spring is
It is easy to fasten to the housing. Further, since the slide spring or the cylindrical spring can realize a low coefficient of friction on the contact surface with the image display device, when an impact is applied to the portable information processing device, the image display device and the slide spring or the cylindrical spring , The contact surface slides freely,
Can absorb shock. The slide spring or the cylindrical spring can realize a highly reliable structure without fear of aging due to heat. In addition, by appropriately determining the elastic coefficient of the slide spring or the cylindrical spring, a portable information processing of a vibration system having a natural vibration period that does not cause excessive vibration with respect to a specific range of impact time is described later. The device can be realized. Accordingly, the present invention has an effect of providing a portable information processing apparatus having a structure that does not deteriorate over time and has a small possibility that the image display device is damaged by an impact.

Embodiment 4 FIG. 4 illustrates a portable information processing apparatus according to a fourth embodiment of the present invention. FIG. 4 is a diagram illustrating a method for designing a shock-resistant support structure of a video display device of a portable information processing device according to the present invention. In the figure, the horizontal axis represents the period ratio (t
/ T). t is the duration DUR of the impact applied to the housing
ATION, T is a natural period of a vibration system including the elastic structure and the image display device. The vertical axis represents the impact transmission rate, which is the ratio of the magnitude of the impact applied to the housing to the magnitude of the impact transmitted to the image display device. For example, in the housing of FIG. 1, the image display device weighing m [kg] and the elastic structures 21 to 24 constitute a vibration system, and the natural vibration period T of the vibration system can be expressed by the following equation. . T = 2π√ (m / k) (1) k is an effective elastic coefficient of the entire elastic structures 21 to 24.

As shown in the figure, the period ratio (t / T) is set to 0.3 to 2.
If it is designed to be in the range of 0, the vibration system inside the portable information processing apparatus resonates, and the shock applied to the housing is amplified and transmitted to the video display device, so that the possibility of damage to the video display device increases. You can see that. In other words, if the period ratio (t / T) is designed to be 0.3 or less or 2.0 or more, the shock applied to the housing is amplified and not transmitted to the video display device, and the video display device is damaged. The likelihood of doing so is reduced. When the video display device to be used is determined based on the use of the portable information processing device or the like, the weight of the vibration system is determined (the weight of the video display device becomes the weight of the vibration system). From the above equation (1), the elastic coefficient of the elastic structure is appropriately selected, and the vibration period of the vibration system is designed to satisfy the condition of the period ratio described above.

In actual use, when a shock is applied to the portable information processing device, which is most likely to occur, the user can move the portable information processing device from the hand, the user's pocket, or the desk to the floor. It is when dropped. In these cases, dropping from almost the same height,
It should be noted. In rare cases, portable information processing devices
Higher heads or bumps may hit you with a greater impact, but the chances of occurrence are very low, and such exceptional impacts may cause portable information processing equipment If broken, users will be convinced. Further, a portable information processing device that has taken an excessive impact countermeasure is heavy and expensive, and often cannot be accepted by the user. Therefore, it is important to realize a portable information processing device that is not easily broken when the user drops the portable information processing device from the hand, the user's pocket, or a desk onto the floor. In actual use, a typical case where the largest impact is applied to the portable information processing device is a case where the portable information processing device is dropped on a concrete floor. As a result of the experiment, the impact continuation time t when the portable information processing device was dropped on concrete from the height at which a person actually held the portable information processing device was 0.5 ms. When the portable information processing device is dropped on a concrete floor, it is necessary to design the image display device so as not to vibrate excessively inside the housing of the portable information processing device. It is important for enhancing the impact. Therefore, the portable information processing device of the present invention is set such that when the portable information processing device is dropped on concrete, the period ratio (t / T) is 0.3 or less or 2.0 or more. t = 0.5m
From s, the condition is that t / T = 0.3 or less, T = 1.7 ms or more. (2) If t / T = 2.0 or more, T = 0.25 ms or less. (3) It is.

Although much softer than concrete, if the portable information processing device is dropped on a wooden floor, a large impact is applied to the portable information processing device. As a result of the experiment, when the portable information processing device was dropped on a wooden floor, the impact duration was
3 ms. Therefore, when the portable information processing device is dropped on a wooden floor from the height at which a person actually holds the portable information processing device, the inside of the housing of the portable information processing device is
It is preferable to design the image display device not to vibrate excessively. Therefore, preferably, the portable information processing apparatus of the present invention has a period ratio (t / T) of 0.3 or less or 2.
Set so that it becomes 0 or more. From t = 3 ms, the condition is t / T = 0.3 or less, T = 10 ms or more. (4) t / T = 2.0 or more, T = 1.5 ms or less. (5) It is.

From the results of the above experiment, when the portable information processing device is dropped on a concrete floor, the natural vibration period T is set to 1.7 ms or more or 0 to prevent the image display device from vibrating excessively inside. .25 ms or less.

Preferably, when the portable information processing device is dropped on a concrete floor or a wooden floor, the natural vibration period T is set to 10 ms or more so that the image display device does not vibrate excessively inside. Alternatively, it is set to 0.25 ms or less. By setting the natural vibration period T within the above range, even when the portable information processing device is dropped on a floor made of any material that is softer than concrete and harder than wood, the image display device vibrates excessively inside. do not do. When the portable information processing device is dropped on a floor softer than a tree, the impact is generally small, so even if there is some excessive vibration inside, the portable information processing device may be damaged. Is small. In theory, if the drop height becomes large,
Although the impact increases and the impact duration also changes, considering the actual use scene, as described above, the drop height may be limited to a drop from a height at which a person has the portable information processing device. Therefore, it becomes almost constant.

The concrete floor is harder than the wooden floor,
The impact duration when the portable information processing device is dropped thereon is short. Since the change in momentum is equal to the impulse, the shorter the shock duration t, the greater the shock. Therefore, 0.5m
For an arbitrary value t shorter than s (when the portable information processing device is dropped on a floor harder than concrete), the period ratio (t
/ T) is more preferably 0.3 or less or 2.0 or more. Therefore, it is preferable that T is equal to or longer than 1.7 ms (see equation (2)). By setting the natural vibration period T within the above range, even when the portable information processing device is dropped from the height of the portable information processing device to a floor made of any material harder than concrete, Does not vibrate the video display device excessively.

More preferably, T is equal to or longer than 10 ms (see equation (4)). By setting the natural vibration period T within the above range, even when the portable information processing device is dropped from a height where the portable information processing device is held by a human to a floor made of any material harder than wood, The image display device does not vibrate excessively.

Reference numerals 21 to 24 denote elastic structures, each having an L-angle shape formed by sheet metal processing, and provided with slide holes 5. An image display device 3 is, for example, a liquid crystal module or a plasma display panel. 4 is a fastening member, for example, a screw or a rivet. 8 is a slide pin. Reference numeral 6 denotes a triangular prism-shaped inclined structure.

The elastic structures 21 to 24 are fastened to the housing 1 by fastening members 4. The image display device 3 is provided with a slide pin 8 through the slide hole 5 in the elastic structures 21 to 24.
Is supported by the slide. The inclined structure 6 is arranged inside the housing 1 such that the edge of the video display device 3 and the inclined surface of the inclined structure 6 are in contact with each other. According to this structure, when an impact is applied in the direction of the arrow 92, the elastic structures 23 and 24 are deformed in the direction of the arrow 92, and the image display device 3 moves along the inclined surface of the inclined structure 6. Since part of the impact energy is converted into rotational energy of the image display device 3, the impact transmitted to the image display device 3 is reduced, and the possibility of damage to the image display device 3 is reduced.

In the first to fifth embodiments, since the elastic structure is made of metal, resin or the like, there is no problem of aging when a buffer material such as gel or urethane is used.
