Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information device, and more particularly to a keyboard-integrated information device in which a cover provided with a liquid crystal panel is attached to a main body having a keyboard or CPU, such as a notebook personal computer, by a hinge mechanism. is there.

[0002]

2. Description of the Related Art In recent years, information devices typified by notebook personal computers have been desired to be light and thin in consideration of ease of use and portability at a location where they are moved. On the other hand, since it is also important to enhance the functions of the information equipment itself, it is desired to mount a CPU capable of performing high-speed arithmetic processing equivalent to that of a desktop personal computer.

[0003] However, C is capable of high-speed arithmetic processing.
When a PU is mounted on a notebook computer, an air-cooling fan must be provided to cool the CPU. As a result, the main body is enlarged and portability is impaired. Further, without the air-cooling fan, the heat generated by the CPU cannot be sufficiently dissipated.

Therefore, the notebook personal computer disclosed in Japanese Patent Application Laid-Open No. H11-345066 is provided with a means for dissipating the heat of the CPU. As shown in FIG. 8, a box-shaped main body 31 has a keyboard unit 32 at its opening 31a.
When the cover 33 is opened in the direction of arrow D, the keyboard unit 32 pivots in the direction of arrow E and tilts in conjunction therewith. As a result, the opening 31a is opened, from which heat in the main body 31 is radiated to the outside.

[0005]

However, in the notebook computer disclosed in Japanese Patent Application Laid-Open No. 11-345066,
Since the keyboard unit 32 has substantially the same area as the upper surface of the main body 31, it is relatively heavy and must be moved to open the opening 31a.

In addition, the keyboard unit 32 generally has a key for touch typing arranged on the near side and a key such as a function key for receiving a strong pressing force for pressing with one finger such as a function key is arranged on the back side. Strong force is applied to the back side lifted at 34. Therefore, it is necessary to consider the strength of the support member 34.

The present invention has been made in view of the above problems, and has as its object to provide an information device capable of dissipating heat in a main body with a simple configuration.

[0008]

In order to achieve the above object, an information apparatus of the present invention has an opening at the front side of the upper surface of a main body, and a palm rest portion for holding a palm when operating a keyboard. It is movably attached to the body to close. When the cover is opened, the driving means moves the palm rest to form a gap between the palm rest and the main body. The heat in the main body is dissipated from this gap.

The driving means includes a driving gear that rotates about the hinge axis of the hinge member together with the cover, a first lever that meshes with the driving gear at one end and moves in the horizontal direction by rotation of the driving gear, and one end. And a second lever attached to the other end of the first lever so as to be rotatable about a rotation axis and the other end attached to a palm rest portion.

When the cover is opened and closed, the drive gear rotates and the first lever moves in the horizontal direction. And the first
The second lever, which receives a horizontal force from the lever, rotates about the rotation axis, and the other end to which the palm rest is attached is lifted in the rotation direction. That is, when the cover is opened, the palm rest portion is lifted, and a gap is formed between the cover and the main body.

The information device further includes a first radiator plate fixed to the first lever in the main body, and a second radiator plate thermally connected to the first radiator plate and fixed to the electronic component. However, when the cover is closed, at least a part thereof is provided so as to overlap in the vertical direction. Therefore, when the cover is opened, the drive gear rotates and the first lever moves in the horizontal direction, so that the first heat sink also moves in the horizontal direction. At this time, when the first radiator plate moves in a direction in which the overlap with the second radiator plate decreases, the radiator area increases.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view showing the notebook computer of the present embodiment, and FIG. 2 is a side view.
This notebook computer has a main body 1 and a hinge 2
The main body 1 includes a cover 3 rotatably mounted thereon, a liquid crystal panel 4 provided on the cover 3, and a keyboard unit 5 provided on the back side of the upper surface of the main body 1.

The front side of the upper surface of the main body 1 is open, and a palm rest 6 is provided so as to close the opening. The palm rest part 6 is where the user places his / her palm when operating the keyboard unit 5.
a, a front surface 6b, and both side surfaces 6c, 6d.

The palm rest part 6 is provided with a hinge part to be described later.
It is attached to the main body 1 so as to rotate about an axis L (indicated by a dashed line in the figure) parallel to the front surface 6a by a not shown (not shown). When the cover 3 is open, the cover 3 is slightly rotated to the front side and is inclined, and a gap 7 is provided between the cover 3 and the main body 1.

FIG. 3 shows a state in which the cover 3 is closed. At this time, the palm rest 6 is not inclined, and there is no gap 7 between the palm rest 6 and the main body 1. In the notebook computer of the present embodiment, the palm rest 6 is driven and rotated with the opening of the cover 3 to form a gap 7.

The means for driving the palm rest 6 will be described. FIG. 4 is a perspective view showing the palm rest 6 and its driving means. As shown in this figure, the driving means includes a first lever 61, a second lever 62, and a driving gear 21. Note that the first and second
The radiator plates 91 and 92 will be described later.

An elongated first lever 61 disposed horizontally.
A gear 61a is formed on the upper surface of one end and meshes with the drive gear 21, and a first rotation shaft 63 perpendicular to one side surface 6c of the palm rest 6 is provided at the other end. Second
One end of the lever 62 is rotatably fitted to the first rotating shaft 63, and the other end is rotatably fitted to a second rotating shaft 64 fixed vertically inside the side surface 6 c. The drive gear 21 is rotatably fitted to a hinge shaft 22 of the hinge 2 (shown in FIG. 1).

The operation of the driving means will be described. FIG. 5 is a sectional view showing a state where the cover 3 is closed. The hinge portion 2 of the cover 3 rotates about a hinge shaft 22 fixed to the main body 1, and the drive gear 21 is attached to the hinge portion 2 so as to rotate with respect to the hinge shaft 22 at the same angle as the cover 3. Fixed.

The palm rest 6 has a hinge portion 8 provided on the front surface 6b side, and a hinge axis L of the main body 1 is rotatably fitted thereto. Here, the palm rest portion 6 is closed and is in contact with the opening 1a of the main body 1 without any gap, and the first and second levers 61 and 62 extend linearly so as to be parallel to the bottom surface of the main body 1.

FIG. 6 shows a state in which the cover 3 is slightly opened by rotating the cover 3 from the closed state shown in FIG.
When the drive gear 21 rotates in the direction of arrow A with the rotation of the cover 3, the first lever 61 is pushed forward by meshing with the drive gear 21.

The second lever 62 receives this forward force from the first rotation shaft 63 and moves the arrow B around the first rotation shaft 63.
The other end (the side fitted to the second rotating shaft 64)
Is lifted. At this time, the second lever 62 lifts up the second rotating shaft 64 while sliding on the second rotating shaft 64 through the hole fitted to the second rotating shaft 64. As a result, the palm rest 6
Rotates in the direction of arrow C about the hinge axis L. And
FIG. 7 shows a state in which the cover 3 is further opened.

As described above, the rotational force of the cover 3 is converted by the drive gear 21 into a forward force. Then, when this force is applied to the second lever 62 that can perform only rotational movement by the first lever 61, it is converted into an upward force, and the second rotation shaft 64 of the palm rest 6 is lifted.

As a result, the palm rest 6 rotates about the hinge axis L, and a gap 7 is formed between the palm rest 6 and the main body 1. As described above, the gap 7 is formed between the palm rest 6 and the main body 1 when the notebook computer is used, so that heat generated in the main body 1 can be radiated from the gap 7.

In the present embodiment, the gap 7 is formed by moving the palm rest 6, but the palm rest 6 is loaded with palms of both hands, so that the palm rest 6 is weighted averagely, and compared with the keyboard unit 5. Since the area is small and not very heavy, the first and second levers 61, 6
2 is sufficient. Therefore, there is no need to particularly consider the strength.

Next, when the cover 3 is rotated and closed from the open state of the cover 3 shown in FIG.
Is performed in reverse. That is, in FIG. 7, the rotational force of the cover 3 in the direction of the arrow A ′ is converted by the drive gear 21 into a backward force. Then, when this force is applied to the second lever 62 that can perform only rotational movement by the first lever 61, the force is converted into a downward force (arrow B ′ in the figure), and the second rotating shaft 64 of the palm rest 6 is pulled down. It is.

As a result, the palm rest 6 rotates about the hinge axis L in the direction of arrow C ′, and the gap with the main body 1 is closed. Thus, when the palm rest 6 is closed when the cover 3 is closed, the size of the main body 1 and the palm rest 6 is smaller than when the gap 7 is formed, so that it is convenient to carry. .

Next, a configuration for more effectively dissipating heat in the gap 7 will be described. As shown in FIG. 4, a first radiator plate 91 is fixed to the first lever 61, and a second radiator plate 92 is attached to the first radiator plate 91 via the heat conductive sheet 10. It is preferable that the heat conductive sheet 10 has flexibility in order to smoothly move the first heat radiating plate 91.

As shown in FIG. 5, the second heat radiating plate 92 is fixed on the CPU 11, which is one of the electronic components generating a large amount of heat, and partially overlaps the first heat generating plate 91 in the vertical direction. It is located like that. When the cover 3 is opened from this state, the first lever 61 is pushed forward, so that
The first radiator plate 91 fixed to the first lever 61 also moves forward.

When the cover 3 is opened, as shown in FIG. 7, the heat radiating areas of the first and second heat radiating plates 91 and 92 are larger than those in FIG. Located near. When the notebook personal computer is used in such a state, the heat generated by the CPU 11 is dissipated by the second heat radiating plate 92 and the first heat radiating plate 91 via the heat conductive sheet 10 and goes out of the gap 7 from the main body 1. . Therefore, heat can be efficiently dissipated even in the CPU 11 located at the rear in the main body 1.

Of course, when the cover 3 is closed, the first radiating plate 91 moves backward together with the first lever 61 and returns to the original position. That is, when the notebook computer is not used, the heat radiation area of the first and second heat radiation plates 91 and 92 is reduced,
Space saving in the main body 1 is achieved.

In this embodiment, the present invention is applied to a notebook personal computer as an example of an information device, but it is needless to say that other information devices may be used. Further, only the driving means provided on one side surface 6c is described, but a similar driving means and a heat radiating plate may be provided on the other side surface 6d (shown in FIG. 1).

[0032]

As described above, the information device of the present invention moves the palm rest to form a gap between itself and the main body, and dissipates heat in the main body therefrom. Since the palm rest portion is a part of the upper surface of the main body, it is not very heavy, and is a member that does not receive much force. Therefore, there is no need to consider strength or the like when moving and supporting the palm rest portion. That is, the configuration is simple.

Further, two heat radiating plates are provided to dissipate the heat generated from the electronic components. One of the heat radiating plates moves forward when the cover is opened to increase the heat radiating area, and at the same time increases the palm rest area. It is configured to approach the gap between the part and the main body. Therefore, even if an electronic component having a relatively large calorific value, such as a CPU, is disposed behind, heat can be efficiently dissipated, and the device design becomes easy.
