Description

  The present invention relates to a slide rotation mounting unit for mounting a movable housing so as to rotate while sliding at least partially overlapping a holding base, and a mobile phone using the unit.

In a mobile phone, an electronic notebook, a personal computer, and other electronic devices, a thin display unit housing having a display unit is vertically long (for example, a mobile phone) or horizontally long (for example, a notebook type or other personal computer). Is fixed in a portrait or landscape orientation, it is inconvenient when viewing the display screen or performing an input operation while viewing the screen. In other words, depending on the type of input work and the display target when inputting data such as creating a document or creating a table and viewing the results and images on the screen, a landscape screen and a portrait screen may be suitable. is there.
Therefore, in the electronic apparatus as described above, the display unit casing is made a movable casing, which is rotated by 90 degrees as necessary, and converted into a vertically long state and a horizontally long state (for example, patents described later) Reference 1).

  For electronic devices that can be used by changing the posture of the movable housing, either attach the holding base to the one end of the base housing with the input unit using a hinge, or use it for a desktop separately from the input unit or the PC. Holding bases are installed, and a movable casing that is an input section casing is attached to these holding bases via a slide rotation mounting unit so as to partially overlap.

The inventors have already proposed a slide rotation mounting unit configured as shown in FIG. 7 to FIG. 10 in order to make the rotating operation of the movable housing smoother (Patent Document 2 described later).
This will be described below.
9 is a partially exploded perspective view of a mobile phone using a slide rotation mounting unit, FIG. 10 is a schematic perspective view of the mobile phone of FIG. 9, and FIG. 11 is a reference posture (basic use) of the movable housing of the mobile phone of FIG. FIG. 12 is an enlarged cross-sectional view taken along arrow CC in FIG. 11.

9 and 10, the holding base 3 overlaps the base casing 5 via a hinge 6 at one end of the base casing 5 of the mobile phone having a transmitter and an input unit (both not shown). It is connected so that it can be folded and opened from the closed state to the open state of about 150 to 170 degrees.
The holding base 3 that is standing at a predetermined angle in use is slid in a state where the lower portion of the movable casing 4 that is an LCD casing having a receiver (not shown) is overlapped via the slide rotation mounting unit b. It is attached to rotate.

As shown in FIG. 9, the slide rotation mounting unit b includes a base plate 1 that is attached to the holding base 3 by an appropriate number (four) of screws 1 a on the opposing surface of the holding base 3 and the movable housing 4, and is movable. And a plate cam 2 attached to the housing 4 by an appropriate number (three) of screws 2a.
The material of the base plate 1 and the plate cam 2 is, for example, a stainless plate.
The plate cam 2 is mounted so as to rotate while sliding by a predetermined amount with respect to the base plate 1 and to stop in a state where it is rotated 90 degrees to the left and right by cam control.
Female screw bosses 20 and 10 corresponding to the screws 2a and 1a are formed on the plate cam 2 and the base plate 1 by, for example, fleshing.

A long-hole-shaped slide guide 11 extending in the up-down direction is formed at a substantially central portion of the base plate 1, and a plate cam is disposed on the base plate 1 on the lower extension of the center line in the width direction of the slide guide 11. Guide pins 12 projecting toward the plate cam 2 are attached upright so that the two cam portions (outer peripheral contour portions) are in sliding contact. The guide pin 12 is formed with a flange portion 12a at the top, and a roller is rotatably attached to a contact portion with the outer peripheral portion of the plate cam 2 in order to reduce friction.
The plate cam 2 is provided with a mounting shaft 21 that is slidably and rotatably engaged with the slide guide 11 in a state of being prevented from coming off. The plate cam 2 and the base plate 1 are slid by the mounting shaft 21. However, they are combined to rotate.
The mounting shaft 21 is tubular and has a flange portion 21a at one end portion. The flange portion 21a is engaged with the slide guide 11 of the base plate 1 on both side back surfaces so as not to be detached. 11 and the shaft end thereof is caulked and fixed to the center mounting hole 22 of the plate cam 2.

The guide pins 12 are guided around the outer periphery of the plate cam 2 when the movable casing 4 is in the basic posture, which is the basic use mode, and when rotated 90 degrees to the left and right from the reference posture. A recess 23 is formed.
The concave portion 23 is a first concave portion 230 in which the guide pin 12 is guided when the plate cam 2 is in the reference posture (FIG. 11), and the guide pin 12 when the plate cam 2 is rotated 90 degrees clockwise from the reference posture. And a third recess 232 guided when the plate cam 2 is rotated 90 degrees counterclockwise from the reference posture.
Only one of the recesses 231 and 232 can be formed so that the plate cam 2 can rotate 90 degrees only in any one direction.

The plate cam 2 is always urged in the downward direction along the slide guide 11 by a spiral torsion spring 13 installed on the back side of the base plate 1.
As shown in FIG. 11, the torsion spring 13 is continuous with the spiral coil portion 130, one arm portion 131 that is continuous with the outer peripheral coil of the spiral coil portion 130 (fixed side), and the inner peripheral coil of the spiral coil portion 130. The other (movable side) arm portion 132 is configured.
The distal end portion of one arm portion 131 is locked or fixed to the upper rear end portion of the base plate 1, and the other arm portion 132 is brought into contact with the outer peripheral portion of the flange 21 a of the mounting shaft 21 with elasticity in the downward direction. Thus, the plate cam 2 is urged in the downward direction.
The spiral coil portion 130 of the torsion spring 13 is pressed to the back side of the base plate 1 by a pressing piece 14 (FIG. 11) cut and raised so as to protrude to the base plate 1 to the back side.
A spring receiving portion 21b having an L-shaped cross section is formed on the outer peripheral portion of the flange portion 21a of the mounting shaft 21 so as to face the back surface of the base plate 1, and the arm portion 132 of the torsion spring 13 is attached to the spring receiving portion 21b. The arm portion 132 of the torsion spring 13 is prevented from being detached from the mounting shaft 21 by being guided or supported or locked.

In order to attach the movable housing 4 to the holding base 3 by the slide rotation attachment unit b, the base plate 1 and the plate cam 2 are attached to the attachment shaft in a state where the elasticity of the torsion spring 13 acts on the plate cam 2 as described above. 21 are connected in advance so as to be slidable and rotatable.
The small screws 1a are passed from the back side of the holding base 3 to the screw guides 31 provided on the bottom plate 30 of the holding base 3, and the small screws 1a are formed on the surface of the base plate 1 facing the holding base 3. The base plate 1 is fixed to the holding base 3 by screwing into each female screw boss 10.
The other machine screws 2a are passed through the screw guides 41 provided on the bottom plate 40 of the movable housing 4 from the surface side of the movable housing 4, and these machine screws 2a are formed on the front side of the plate cam 2. Screwing into each female screw boss 20, the plate cam 2 is fixed to the back side of the movable housing 4.
When the movable casing 4 is attached to the holding base 3, the movable casing 4 is attached in a state where the lower end of the movable casing 4 does not come into contact with the hinge 6 (does not interfere) when the movable casing 4 rotates after the attachment. This is to avoid wear of the movable casing 4 and the outer periphery of the central tubular portion of the hinge 6 that is a part of the holding base 3.

  As described above, in the folding cellular phone in which the movable casing 4 is attached to the holding base 3 by the slide rotation mounting unit b, the movable casing 4 is in the reference posture as shown in FIG. When the slide rotation mounting unit b is in a certain vertical position), the guide pin 12 of the base plate 1 is guided to the first recess 230 of the plate cam 2 as shown in FIG.

In order to convert the movable casing 4 from the reference posture to a horizontally long display mode rotated 90 degrees clockwise, for example, the movable casing 4 is rotated clockwise while being pushed up (or lifted) along the holding base 3. . At this time, the mounting shaft 21 rotates while sliding upward along the slide guide 11.
When the movable casing 4 is rotated 90 degrees clockwise, the guide pin 12 of the slide rotation mounting unit b is guided to the second recess 231 of the plate cam 2, and the movable casing 4 is rotated 90 degrees clockwise. Change posture to landscape state.
When the movable casing 4 is rotated 90 degrees counterclockwise, the movable casing 4 changes its posture to a horizontally long state in the opposite direction of 180 degrees.
In a state in which the plate cam 2 is raised to the highest level along the base plate 1, the movable arm 132 of the torsion spring 13 exhibits a state in which it is inclined upward and viewed from the back side of the base plate 1.

In the cellular phone, the movable casing 4 is converted into a horizontally long posture and the guide pins 12 are guided to the left and right recesses 231 or 232, and at the same time, the display mode of the movable casing 3 is converted according to the posture. No switch is provided.
When the movable casing 4 returns from the horizontally long posture to the vertically long reference posture, a similar switch for adjusting the display mode to the posture is provided in the mobile phone.

According to the slide rotation mounting unit b already proposed by the inventors, the rotating slide operation of the movable housing 4 is extremely smooth due to the above-described configuration.
However, according to the above-described slide rotation mounting unit b, since the end portion of the arm portion 132 of the torsion spring 13 is received by the mounting shaft 21 that rotates together with the plate cam 2, various restrictions are imposed on the design.
For example, the spring receiving portion 21 b that supports or locks the arm portion 132 of the torsion spring 13 needs to be formed in a bowl shape so as to be continuous with the outer peripheral portion of the mounting shaft 21 that rotates together with the plate cam 2 with respect to the base plate 1. Therefore, the length (or thickness) L of the mounting shaft 21 shown in FIG.
Therefore, particularly in the case of a small electronic device, there is a risk that it will not be possible to meet the demand for further reduction in thickness or size.
