Description

  The present invention relates to an openable electronic device including a parallel biaxial hinge device. More specifically, the first housing and the second housing can be prevented from interfering with each other when the first housing and the second housing are oscillating, and the first housing and the second housing are opened 180 degrees. The present invention relates to an electronic device that can sometimes bring housings close together.

In general, it is preferable in terms of visibility and operability that a portable information terminal is small when carried and is large when used. For this reason, there are known a type in which two casings are enlarged by sliding them in use, a type in which two casings are connected by hinges so that they can be opened and closed, and a type in which they are opened in use.
What is connected by this hinge to open and close, so-called foldable (or foldable), is provided with one shaft body, parallel with two shaft bodies provided in parallel. One having a biaxial hinge device is known. The parallel biaxial hinge mechanism is preferred in that there is no portion where the hinge mechanism protrudes from the housing.

Techniques relating to small electronic devices and biaxial hinge mechanisms in which a pair of housings are connected so as to be openable and closable via a parallel biaxial hinge mechanism are known (see, for example, Patent Documents 1 to 3). However, in the casings of the techniques of Patent Documents 1 to 3, in order to prevent the corners on the inner side from folding from interfering with the corners during the opening / closing operation, the inner corners have a relief shape (for example, the corners have a predetermined shape). R shape with rounded radii) is formed. For this reason, the technology has not been able to meet the demand to increase the size of the display screen while keeping the device downsized. In other words, in a foldable electronic device, when the casings are opened 180 degrees, a uniform display screen is formed in which the display screens of the pair of casings are continuous to increase the size of the display screen. It was a configuration that could not be.
On the other hand, technologies relating to an information terminal device and a mobile terminal that aim to reduce the size of the device and enlarge the display screen are also known (see, for example, Patent Documents 4 and 5).

It is explanatory drawing which shows a state opened.

In the state of FIG. 4A, there are predetermined intervals S between the folding center line C and the first housing 1 and between the folding center line C and the second housing 2. When swinging is started around the swing center line O, the position of the swing center line O is at the corner of the lower end of the second housing 2 on the folding center line C at least when swinging is started. It becomes. In any case, at least if the rocking is not started at this position, the corners of both cases immediately interfere with each other. The relationship at the start of the oscillation is as follows.
L ₁ = J + S = R * cos θ R> J + S

When the first casing 1 and the second casing 2 are swung by an angle θ to make them open, the corners of the first casing 1 and the corners of the second casing 2 are denoted by reference numeral 11. In order to prevent interference at the position, as shown in FIG. 4B, the second slide shaft 5 located at the radius R farthest from the swing center point O is separated from the folding center line C by the swing distance R. ing. When swinging by this angle θ, the swing radius R of the second slide shaft 5 and the distance between the center of the second slide shaft 5 and the folding center line C are the distance L at the start of swinging of the second slide shaft 5. ₁ and the intermediate distance L ₂ are as follows. The corners of the first housing 1 and the corners of the second housing 2 may be virtual corners in design, and are not limited to actual corners. Similarly, the swing center point O is not limited to an actual swing point, and is a concept including a virtual swing point.
L ₂ = R L ₂ > L ₁

FIG. 4C shows a state in which the first housing 1 and the second housing 2 are opened 180 degrees. The distance (d ≧ 0) between the first housing 1 and the second housing 2 at this time is, for example, a display screen continuous by display units provided in both the first housing 1 and the second housing 2. In this case, d = 0. When it opened the 180 degrees, if the distance L ₃ from the folding center line C at the end swinging of the second slide shaft 5, the following relationship is established. As shown in FIG.
L ₃ = H + d = R * sin θ + d
When S + J ≧ d + H, L ₂ > L ₁ > L ₃
When S + J <d + H, L ₂ > L ₃ > L ₁
It becomes the relationship.

That is, in order to prevent the corners of the first housing 1 and the corners of the second housing 2 from interfering with each other, when both housings are swung by an angle θ, the center of the second slide shaft 5 is it is necessary to largest distance L ₂ between the folding centerline C. In other words, when the radius R from the swing center O at the start of the swing to the center of the second slide shaft 5 is swung (angle θ) with respect to the folding center line C (angle θ) (FIG. 4B). )), The distance L ₂ between the center of the second slide shaft 5 and the folding center line C needs to be maximized (L ₂ ≧ R). The groove shape of the first cam surface 6 and the second cam surface 9 formed on the cam plate 10 needs to be formed so as to satisfy this condition.

  Next, the opening / closing operation of the first housing 1 and the second housing 2 will be described. The first casing 1 and the second casing 2 will be described using an example in which the “closed state” is changed to the “opened state”. When the first housing 1 is swung from the “closed state” to an intermediate position (an angle at which the first housing 1 and the second housing 2 are opened by 90 degrees), the first slide plate 21 is moved on the first housing side 1. It swings with respect to the cam plate 10 integrally with the first housing 1. The third slide shaft 7 is guided by the third cam groove 13 of the second cam surface 9, and the fourth slide shaft 8 is guided by the fourth cam groove 15 of the second cam surface 9, and swings and moves to the second housing. 2 moves in a direction in which the first housing 1 leaves. On the second housing 2 side, the second slide plate 31 swings with respect to the cam plate 10 integrally with the second housing 2. The first slide shaft 4 is guided by the first cam groove 12 of the first cam surface 6, and the second slide shaft 5 is guided by the second cam groove 14 of the first cam surface 6. The second housing 2 moves away from the body 1 (see FIGS. 3A and 3B).

  Further, when the swing operation is performed from the intermediate position to the “open state” position, the third slide shaft 7 is moved to the third cam groove 13 and the fourth slide shaft 8 is moved to the fourth cam groove 15 on the first housing 1 side. The first housing 1 is moved in the direction in which the first housing 1 approaches the second housing 2 while being guided to swing. On the second housing 2 side, the first slide shaft 4 is guided by the first cam groove 12 and the second slide shaft 5 is guided by the second cam groove 14 so as to swing and move to the first housing 1. On the other hand, the second housing 2 moves in a direction in which the second housing 2 approaches (see FIGS. 3B to 3C). As described above, the first housing 1 and the second slide shaft 5 and the first cam surface 6, the third slide shaft 7, the fourth slide shaft 8 and the second cam surface 9 act as the first housing 1 and The first casing 1 and the second casing 2 can be brought as close as possible when the second casing 2 is in the “open state” while avoiding interference during the swinging operation. That is, the user can prevent the interference at the inner corner by simply performing an operation of opening and closing the first housing and the second housing as usual. Further, when changing from the “open state” to the “closed state”, the reverse operation is performed.
