Description

  The present invention relates to a portable electronic device such as a mobile phone or a portable information terminal. For example, a movable unit that also serves as a lid is slidably moved with respect to a fixed unit in which a main device is accommodated to open and close the lid. The present invention relates to improvement of portable electronic devices.

  A mobile phone that can be expanded and contracted by moving a movable unit having a transmitter, a key button, etc. slidably with respect to a fixed unit housing the mobile phone body. Has been proposed (see Patent Documents 1 and 2).

    Further, a movable unit having a display unit such as a transmitter and a liquid crystal display is slidably moved upward with respect to a fixed unit which is a case main body for housing the device main body so as to expose a key button on the fixed unit. A portable telephone set has been proposed (see Patent Document 3).

  Each of the mobile phones having these sliding movable units includes a guide unit that relatively guides the movable unit and the fixed unit, and a lock unit that locks the movable unit at the extended position and the contracted position. However, in any form, the movable unit is simply moved by hand against a leaf spring (see Patent Document 1) or a spring-biased ball bearing (see Patent Document 3).

  However, since all of these conventional mobile phones only move the movable unit against the warping force of the leaf spring and the expansion and contraction force of the coil spring, the spring force is generated by frequent expansion and contraction of the movable unit. When weakened, the force with which the movable unit is held with respect to the fixed unit is weakened, and the movable unit may not be held with respect to the fixed unit.

  On the other hand, recently, a microphone unit of a mobile phone has been made freely removable with respect to the main unit, and the microphone unit is inserted / removed slightly at an unstable intermediate position in a compressed state of a torsion spring fixed between the microphone unit and the main unit. If it exceeds, a mobile phone has been proposed in which the microphone unit moves rapidly to either the extended position or the contracted position of the microphone and is held in either the extended state or the contracted state of the microphone unit (patent) Reference 4).

  In this cellular phone, the microphone unit is securely held in the extended position and the contracted position by a strong acting force from the unstable intermediate position of the torsion spring to the stable position. Since the spring force acts on the entire surface, the force to be applied to the microphone unit when expanding and contracting the microphone unit must be large, so the operability is low, and the friction between the microphone unit and the main unit is severely worn. When this wear progresses, rattling occurs due to a gap generated between the microphone unit and the main unit, and there is a possibility that the expansion and contraction of the microphone unit cannot be performed smoothly.

  Recent mobile phones have added a communication function and various functions associated therewith. For example, mobile phones equipped with a digital camera are widely used. It is required to move the movable unit not only upward but also downward to hide or expose the parts with different functions above and below the fixed unit as the device body. It could only move in one direction and could not meet such demands.

A movable unit elastic holding means 28 for holding 20 in any of the above three positions with respect to the fixed unit 16 is provided.

  As shown in FIGS. 7 to 9, one end 26 </ b> M of the torsion spring 26 is latched by a fixing pin 30 attached to one side of the recess 17 of the fixing unit 16 at a substantially intermediate position in the vertical direction. The other end 26 </ b> S is latched to an engagement portion, for example, an engagement pin 32, supported through the long hole 20 </ b> H of the movable unit 20, and the engagement pin 32 slides on the recess 17 of the fixed unit 16. The surface 36 is engaged.

  In the illustrated form, the engaging pin 32 has a rotating roller 34 made of rubber or other wear-resistant material at a portion engaging with the sliding surface 34. The rotating roller 34 can move along the sliding surface 36 with a small resistance while rolling on the sliding surface 36.

  The sliding surface 36 is formed on the inner peripheral surface of the dent opposite to the side to which one end 26S of the torsion spring 26 is fixed, and the sliding surface 36 is an end portion of the torsion spring 26 in the middle of the substantially vertical surface portion. 26V, a V-shaped neutral holding position lock recess 38 which is provided so as to be farthest from the end portion in the horizontal direction and engages with the engagement pin 32, and a vertical surface portion. Displacement holding position lock recesses 40 and 42 which are provided at the ends and into which the engagement pins 32 engage. These lock recesses 38, 40, 42 constitute a lock portion 43 of the movable unit elastic holding means 28.

  When the movable unit 20 is in the neutral holding position Pn with respect to the fixed unit 16, the engaging pin 32 is engaged with the neutral holding position lock recess 38, and the movable unit 20 is in the first position with respect to the fixed unit 16. When in the displacement holding position P1, the engagement pin 32 is engaged with the first displacement holding position lock recess 40, and the movable unit 20 is in the second displacement holding position P2 with respect to the fixed unit 16. At this time, the engaging pin 32 is engaged with the second displacement holding position lock recess 42 to elastically hold the movable unit 20 at these holding positions Pn, P1 and P2.

  When the movable unit elastic holding means 28 moves the movable unit 20 while compressing the torsion spring 26 and slightly exceeds the unstable neutral point of the torsion spring 26 toward one of the holding positions, the movable unit elastic holding means 28 moves over the movable unit 20. The fixed unit 16 functions to rapidly move to one of the holding positions and elastically hold at that position, the details of which will be described below with reference to FIGS.

  When the movable unit 20 or the slices 24, 24 ′ are moved with respect to the fixed unit 16 so as to be pushed upward from the neutral holding position Pn of FIGS. 1, 2 and 7 by the finger, the end portion 26M of the torsion spring 26 is moved. The engaging pin 32 that is latched is lifted along the upper inclined surface 36U of the sliding surface 36 while being compressed to the right in FIG. 10 along the long hole 20H of the movable unit 20 while compressing the torsion spring 26. To do. At this time, the spring force that the engaging pin 32 acts on the upper inclined surface 36U of the sliding surface 36 is obliquely upward as indicated by the vector in FIG. However, since the spring force still includes a downward component of the upper inclined surface 36U, when the finger is released from the movable unit 20 or the sliders 24, 24 ', the spring force returns to the original neutral holding position Pn.

  The movable unit 20 or the slices 24, 24 'are further moved upward from the position of FIG. 10, and the unstable intermediate point where the torsion spring 26 is most compressed at the corner 36UA which is the boundary between the upper inclined surface 36U and the vertical surface portion. When the position of FIG. 11 is reached, even slightly exceeding, the combined spring force is obliquely upward not including a downward component on the sliding surface 36 as indicated by the vector of FIG. The movable unit 20 rapidly moves toward the first displacement holding position P1 even when the finger is released from 24 ', and the engagement pin 32 engages with the first displacement holding position lock recess 40, and this It is elastically held at the first displacement holding position P1.

  On the contrary, when the movable unit 20 or the slices 24, 24 ′ are moved relative to the fixed unit 16 so as to be pushed down from the neutral holding position Pn of FIGS. When the finger is released while engaged with the downward inclined surface 36L, the movable unit 20 attempts to return to the original neutral holding position Pn. However, if it slightly exceeds the lower corner portion 36LA that is an unstable intermediate point, the movable unit 20 is movable. Even when the finger is released from the unit 20 or the sliders 24, 24 ', the movable unit 20 moves rapidly toward the second displacement holding position P2, and the engaging pin 32 is locked to the second displacement holding position lock recess 42. And is elastically held at the second displacement holding position P2.

It consists of semi-circular depressions provided at the top and bottom, but as shown in FIG. 15, the vertical surface portion of the sliding surface 36 faces upward and downward (the end 26S of the torsion spring 26 is hooked). The upper end of the inclined surface 36U ′ may be formed by being inclined in the direction opposite to the portion. This is because the locking recesses 38, 40 or 38, 42 are angled surfaces 36U, 36U formed so as to protrude between the neutral holding position Pn and the first or second displacement holding position P1 or P2. It means that it consists of both ends of 'or 36L, 36L'.

  What should be noted in the above embodiment is that the end of the torsion spring 26 spanned between the fixed unit 16 and the movable unit 20 on the movable unit 20 side is directly fixed to the movable unit 20. Rather, it is supported by penetrating the movable unit 20 and is latched by the engaging pin 32 that engages the sliding surface 36 on the fixed unit 16 side. For this reason, the force of the torsion spring 26 does not act as a force for pressing the entire movable unit 20 against the fixed unit 16, but only acts on the sliding surface 36 with a small area via the engagement pin 32. The unit 20 can be moved with a small force with respect to the fixed unit 16, and the wear of the sliding portion is small, so that the life can be extended.

  Another embodiment of the present invention is shown in FIG. 16 and FIG. 17, in which the movable unit 20 faces the fixed unit 16 in a lowered holding position (FIGS. 1 to FIG. 17). 15 corresponding to the neutral holding position Pn) and Pd and the upward holding position (corresponding to the first displacement holding position P1 in FIGS. 1 to 15) Pu which moves upward from the facing state of the fixed unit 16 and opens the fixed unit 16. Have In this embodiment, the sliding surface 36 with which the engaging pin 32 engages is composed of a substantially vertical surface portion over the entire length, and is a hemispherical lock corresponding to the lowered holding position Pd and the raised holding position Pu. Except for having the concave portions 38 and 40, the embodiment is substantially the same as the embodiment of FIGS. 1 to 15, and the same portions are denoted by the same reference numerals. This embodiment is advantageous when applied to a mobile phone or the like that does not include the camera of the previous embodiment.

    Also in this embodiment, when the movable unit 20 is pushed up from the lowered holding position Pd of FIG. 7 with a finger, the engagement pin 32 slides vertically along the long hole 20H while compressing the torsion spring 26. Ascending along the surface 36, the torsion spring 26 is rapidly moved to the rising holding position when it slightly exceeds the unstable middle point where the compression is the most (the point where the combined force of the vector branches downward and upward). The engaging pin 32 engages with the lock recess 40, and the movable unit 20 is held at the raised holding position Pu. When the movable unit 30 is pushed downward from the raised holding position Pu with a finger, the movable unit 20 is rapidly lowered when the unstable intermediate point of the torsion spring 26 is slightly exceeded, and the engagement pin 32 enters the lock recess 38. The movable unit 20 is engaged and held in this position.

    In the embodiment of FIGS. 16 and 17, the end 26M on the movable unit side of the torsion spring 26 is not directly fixed to the movable unit 20 but is movable unit, as in the embodiment of FIGS. Since the engagement pin 32 is fixed to the engagement pin 32 penetrating through 20 and slidably engaged with the sliding surface 36 provided on the fixed unit 16 side, the movable unit 20 is moved. The resistance is small, the operation can be performed smoothly with a small force, and the life can be extended by reducing the wear between them.

  In the above-described embodiment, the lock portion of the movable unit elastic holding means 28 includes the lock recesses 38, 40, 42, 40 ′, and 42 ′ provided on the sliding surface 36. A stopper is provided between the unit 16 and the movable unit 20 so that the movable unit 20 is locked to the fixed unit 16 at each holding position Pn, P1, P2, Pd, Pu, and these stoppers constitute a lock portion. You may do it.

  Further, in the above embodiment, the movable unit 20 is moved like a bow with respect to the fixed unit 16 for the convenience of use in a mobile phone. Of course, it may be moved. In the illustrated embodiment, the engaging portion that engages the sliding surface of the fixed unit 16 includes an engaging pin 32 that is wound around the end portion 26M of the torsion spring 26 and attached to the torsion spring 26. However, the end portion of the torsion spring 26 itself can be bent and the bent portion itself can be used as an engaging portion.

  The present invention can reliably hold the position of the movable unit with respect to the fixed unit without weakening the spring force even if the movable unit is frequently moved with respect to the fixed unit. The movable unit can be moved smoothly with a small force such as a finger, and the operability can be improved. In particular, the movable unit can be moved in both the upper and lower directions. Therefore, it can be suitably used for portable electronic devices having various functions.
