Description

  The present invention relates to a slide device and an electronic device such as a mobile phone, a mobile, and a small personal computer using the slide device.

  For example, an operation unit in which numeric keys and function keys are arranged is provided on the upper surface of the main body, and a display unit such as a liquid crystal panel for displaying a predetermined display is provided on the upper surface of the superposition unit superposed on the main body. A slide type with a structure in which the main body part and the overlapping part slide relative to each other in the front-rear direction, a rotating slide type that rotates and slides in the direction of the overlapping surface, and a combination of these slides and a 90-degree turn slide after opening the slide into a T-shape Conventionally, there has been a mobile phone or the like that can be used by switching its rotation.

  For example, in this slide type, a guide rail portion as a slide guide portion is provided directly or indirectly (meaning including a member provided in the main body portion) with an interval between the left and right overlapping portions, and the left and right guide rail portions are provided. A slide portion that is slidably engaged is provided directly or indirectly on the main body portion, and the slide portion is slid relative to the guide rail portion so that the overlapping portion and the main body portion are slidably connected.

  A slide device that realizes such a slide-type mobile phone slide structure has a slide portion that is slidably engaged between slide guide portions provided on the left and right sides, as described above, with respect to the main body portion. Thus, the overlapping portions are slidably connected.

  In the case of a rotating slide type, for example, a slide guide portion such as an arc-shaped guide groove that serves as a guide when rotating with the fulcrum portion as a rotation fulcrum is provided in the main body portion, and the overlapping portion rotates to this slide guide portion. A slide part that is slidably engaged is provided, and is pivotally attached at a pivotal fulcrum part. At the same time, the guide part is pivotally slidably engaged with the slide guide part, and the overlapping part is pivotally slidably connected to the main body part. It is the structure to do.

  By the way, in the slide type or rotary slide type mobile phone using the slide device that slidably or rotatably slides the main body part and the overlapping part in this way, the operation part of the main body part is concealed by the overlapping part. Positioning and holding at the overlapped closed position and the slide open position where the operation part is exposed by moving it in the front-rear direction or rotational direction so as to shift the overlapped part (close biasing or opening biasing or click engagement) It is desirable to make it so.

  Therefore, in order to meet such a demand, one end of the elastic portion is directly or indirectly connected to the first member and the other end is directly or indirectly connected to the second member. Thus, there is a slide device configured to generate a return bias (close bias) or a forward bias (open bias) between the first member and the second member.

  That is, for example, the wire is wound in a coil shape or a spiral shape in the middle between both ends of the wire, and the torsion spring formed in a generally square shape with the wound portion at the top is used as an elastic portion. One end of the spring is connected to the first member, the other end is connected to the second member, and the connecting portions at both ends of the torsion spring are separated from each other by the spring bias (expansion bias) to the first member. In some cases, when the second member is slid or rotated, the urging force is generated in the sliding direction.

  According to this conventional apparatus, by using the urging in the sliding direction resulting from the angle expansion urging of the elastic portion, for example, when the overlapping portion is slid with respect to the main body portion of the sliding mobile phone, the predetermined sliding movement position Until this position is maintained at the overlapped position so that a closed bias is generated, and when the overlapped portion is moved beyond the predetermined slide movement position with respect to the main body, this time, an open bias is generated in reverse. A positioning and holding function of positioning and holding the overlapping portion at the slide open position can be realized.

JP 2005-291315 A

  In this type of slide device, as the elastic portion, the torsion spring or the like that generates the above-described widening bias is employed because it is easy to manufacture and low in cost, and is thin and easy to assemble.

  On the other hand, in order to increase the elastic force (biasing force), it is necessary to increase the number of windings of the wire. However, if the winding diameter is the same diameter and a plurality of windings are made into a coiled winding part, the wire is wound only by the number of windings. Since it overlaps in the vertical direction, it will not be able to respond to thinning.

  For this reason, for example, a torsion spring having a spiral winding portion that can be wound in a flat shape so as not to overlap as much as possible in order to increase the elastic force while realizing thinning has been proposed.

  In other words, if you want to strengthen the urging force in the sliding direction such as return urging and forward urging, you can bend it into a flat and thin overall view (plan view) by winding it several times in a spiral shape. It is configured such that a strong energizing force is generated by energizing and energizing both ends of the unwinding spring by bringing them closer to each other and connecting them.

  However, the conventional elastic portion (torsion spring) composed of a spiral wound portion that generates this strong biasing force is generally wound a plurality of times in a spiral shape so that the diameter gradually decreases from the outside to the inside, for example. Due to the structure of unwinding from the winding center, the deformation strength at the left and right with the winding center as the boundary is different, and the right and left balance of the spring bias may be poor and stress concentration may occur. Due to the poor quality, the winding part may bend in the vertical direction, causing the winding part to contact the surface of the member, causing unnecessary slide resistance, or unstable movement, for example, the winding part with respect to the connected winding wire There is a concern that the winding of the winding part may be caught by a member that moves relative to the winding part and may not slide smoothly, or the member surface may be scratched or generate abnormal noise.

  That is, the torsion spring having a generally square shape is flat and can be thinned, but as shown in FIG. 11, there is a risk that the torsion spring will bend up and down inevitably. In particular, one of the winding lines wound in a left-right shape with the spiral winding portion at the apex is unwound from the outside of the spiral winding portion, while the other is unwound from the spiral center portion (vortex winding). Although it is easy to manufacture and excels in mass productivity, it is easy to manufacture and has a structure where the center part is connected to the base of the unwinding line. (When the spring is operated in which the left and right unwinding lines of the spring expand or contract against the bias), the unwinding angle of the base of the unwinding line is not the same on the left and right, and the bases of the left and right unwinding lines are Since the winding diameters of the continuous unwinding portions are completely different, the deformation strength at the unwinding line receiving the force is different, and the balance between the left and right in the spring bias is not uniform, causing deflection in the vertical direction.

  Therefore, as described above, there is a possibility that the sliding operation and the durability of the spring may be hindered. In particular, as shown in FIGS. 11 and 12, a slide guide portion 7 as a guide portion is provided on one of the first member and the second member, and a slide portion 7 as a guide portion that is slidably engaged with the other member is provided on the other side. A slide part that scratches or moves the surface of the slide guide part 7 that may also be a surface exposed as an external appearance when the torsion spring 3 provided between the first member and the second member bends up and down. 7 There is a possibility that the slide movement may not be smooth due to being caught on the front edge, or the slide may not be able to be performed.

  The present invention finds that the torsion spring having a generally square shape has the above-mentioned problems, and a predetermined cover plate excellent in mass productivity is simply superposed on the winding part and one winding line. The above-mentioned spring shape that solves the problem by mounting and easily generates a strong biasing force (for example, in a flat torsion spring having a generally square shape) reduces the vertical deflection. Smooth sliding can be realized, and even if deflection occurs, the contact part is a wide flat plate surface, so a smooth slide is secured without being caught, and there are defects such as scratches, abnormal noise and durability It is an object of the present invention to provide a revolutionary elastic portion that is extremely excellent in that it can hardly occur, thereby providing an innovative slide device and an electronic device using the slide device.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  The elastic portion 3 according to the present invention is formed of a flat and generally bendable spring having a connecting end 4 on the left and right sides and a winding portion 5 in the middle. One end of the connecting end 4 is directly or indirectly connected to the first member 1 and the other end is directly or indirectly connected to the second member 2 so as to cause an expansion urging force that causes the connecting ends 4 to be separated from each other. However, the flat direction is set so as to cover both the winding portion 5 of the elastic portion 3 and one of the winding wires 6 that cause an expansion bias between the left and right winding wires 6. Since a cover plate 8 having a flat surface with no protruding portion is attached to the outer surface as the plate surface direction, deformation strength (at least deflection strength) is reinforced by the cover plate 8 so that the winding portion 5 is in the flat direction. It becomes difficult to bend in the vertical direction perpendicular to each other.

  Even if the effect of preventing deflection is insufficient, at least one outer surface is a flat surface over a wide range, so that a flat contact surface without unevenness is formed on one side. Therefore, even if the deflection prevention is insufficient and the vertical deflection occurs, the contact part is a wide flat surface, and this flat surface may be caught on the side that is likely to be caught. There is no fear of being caught by the member, and a smooth spring operation is ensured.

  Therefore, simply by attaching a thin plate-like cover plate 8 having a predetermined size excellent in mass productivity to the winding portion 5 of the elastic portion 3 and the one winding wire 6 (for example, to the winding wire 6). The cover plate 8 that forms a wide flat contact surface so as to cover the one winding wire 6 and the winding portion 5 is overlapped so that only the other winding wire 6 does not hinder the spring operation. In addition, if the wide and narrow operating range is configured so that it can be freely bent without interfering with the cover plate 8, it can be flexed during the spring operation while responding to the demand for thinning, by simply attaching it to the elastic portion 3). Even if the winding part 5 tries to bend up and down during the spring operation, the winding part 5 will not touch the upper and lower members and will not rub or get caught when sliding, ensuring a smooth operation and unstable sliding movement. And it does not interfere with slide movement. And thus Xiu also in durability without also occur giving or unusual noise.

  Further, for example, it is possible to suppress the deflection only by attaching the cover plate 8 to the spiral torsion spring having a general shape that is spirally wound in the middle of the wire so that a strong bias is generated for easy manufacture. it can.

  That is, as explained in the prior art, the left and right unwinding lines 6 have a large unwinding angle and a large diameter at the unwinding position between the outer side and the center part, and therefore the left and right biasing balance is poor. Although there is a risk of bending up and down during the spring operation, the present invention can be reinforced by merely attaching the cover plate 8 and can be prevented from bending up and down during the spring operation.

  Further, even if the deflection occurs, the contact surface is a flat surface having a wide area (a flat contact surface having a wide range covering the winding portion 5 and one of the unwinding lines 6). One of the member 1 and the second member 2 is provided with a plate-like slide guide portion 7 having both edges as guide rails as a guide portion 7, and the other is provided with a plate-like slide portion 7 slidably engaged with the guide portion 7. 7, the elastic portion 3 is provided between the slide member 7 and the slide guide portion 7 between the first member 1 and the second member 2, and both end portions thereof are respectively interposed through the guide portions 7. When connecting to each member 1, 2, the slide guide portion 7, which can be made to look by bending up and down, is scratched, or the elastic portion 3 is caught on the plate edge (front edge) of the slide portion that slides and slides. It doesn't go smoothly So that the it is possible to prevent or could not Ido.

  In addition, the cover plate 8 can be easily retrofitted or reduced in thickness by setting the overlapping configuration of the cover plate 8 and the winding portion 5 and the unwinding line 6. For example, the cover plate 8 can be set to be as thin as the thickness of the winding portion 5 and the winding wire 6, and the other winding wire 6 is not on the side where it overlaps with the winding of the winding portion 5, but the opposite winding Smooth rotation (spring action) is easily achieved by superimposing the turning part 5 and the one unwinding line 6 on the same plane and forming a flat wide contact surface on this side by the cover plate 8. It can be ensured, and the thinning can be maintained as usual.

  Specific embodiments of the present invention will be described with reference to the drawings.
