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, the elastic portion employs a torsion spring or the like that generates the above-described widening bias because it is easy to manufacture and inexpensive, 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 turns are made into a coiled winding part, the wire will Since it overlaps in the vertical direction, it will not be able to respond to thinning.

  Therefore, for example, as shown in FIG. 16 to FIG. 19, a torsion spring having a spiral winding portion that can be wound in a flat shape so as to avoid overlapping as much as possible in order to increase the elastic force while realizing a thin shape is proposed. Has been.

  In other words, when it is desired to strengthen the urging force in the sliding direction such as the return urging force and the forward urging force, the spring is wound in a spiral shape and is a flat and thin overall view (plan view) and is a bendable spring. And, it is configured such that a strong urging force is generated by a powerful widening urging force by connecting the unwinding both ends close to each other.

  However, the conventional elastic portion (torsion spring) composed of the spiral winding portion that generates this strong biasing force is wound by winding a plurality of times in a spiral shape so that the diameter gradually decreases from the outside to the inside. Due to the structure of unwinding from the center, the left and right deformation strength differs from the center of the winding, and the right and left balance of the spring bias may be poor and stress concentration may occur. There is a concern that a deflection occurs in the direction and the winding part comes into contact with the member surface to cause unnecessary slide resistance, movement becomes unstable, smooth sliding cannot be performed, or abnormal noise is generated.

  That is, one of the winding lines wound in a left and right shape with the spiral winding part at the apex is unwound from the outside of the spiral winding part, while the other is unwound from the spiral center part ( The center of the spiral is connected to the base of the unwinding line), so that the left and right unwinding lines of the U-shaped approach and move away from each other (by widening biasing or against this biasing) (When the left and right unwinding lines expand and contract) The unwinding angle of the base of the unwinding line is not the same on the left and right, and the winding diameter of the unwinding part where the bases of the left and right unwinding lines are connected is completely different Since the deformation strength at the unwinding line receiving the force is different and the left and right balance in the spring biasing is not uniform, deflection occurs in the vertical direction during the spring operation.

  Therefore, as described above, there is a possibility that the sliding operation and the durability of the spring may be hindered.

  The present invention has found that there is the above-mentioned problem in the spiral-shaped overall helical spring torsion spring that can easily realize a thin and strong biasing force, and solves this by improving the winding shape, This winding shape setting makes it easy to create a thin and powerful urging force, but also reduces the vertical deflection, enabling smooth sliding and less likely to cause defects such as scratches, abnormal noise, and durability. In addition, it is possible to realize a revolutionary elastic part that can be expected to further increase the urging force, in other words, to increase the spring load, thereby providing an innovative slide device and electronic equipment using the slide device. The purpose is to do.

  The gist of the present invention will be described with reference to the accompanying drawings.

And the base of the other unwinding wire 6 and the base of the other unwinding wire 6 are not connected to the base of the other unwinding wire 6. The winding portion 5 is configured to be continuously provided on the outside of the winding portion 5, and the winding portion 5 is wound in a spiral shape so that the diameter gradually decreases from the outside to the inside, and the wound wire is further removed without going out at the center portion. On the contrary, it is wound in a spiral shape so as to gradually increase in diameter from the inside to the outside while being polymerized, and it is a flat spiral shape and is wound from the outside The material is again unwound from the outside, and the unwinding angles of the left and right unwinding wires 6 with respect to the winding portion 5 are substantially the same, and the unwinding wire 6 has the shape of the tip portion with respect to the winding portion 5.

  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 winding portion 5 of the elastic portion 3 that causes an expansion urging force between the left and right unwinding wires 6 is not spirally wound with the same diameter but is spirally wound. Because the winding is wound multiple times, even if the urging force is strengthened, the wire material is superposed in the vertical direction by the number of turns, so that it does not become thick, but it is wound in a spiral shape to meet the demand for thinning It is a structure that can increase the urging force while responding.

  In addition, the present invention is not configured to wind in a spiral shape and unwind from the outside and the center portion of the spiral center, but the wound portion 5 of the elastic portion 3 is wound so that the diameter gradually decreases, In addition, it is polymerized in the thickness direction with respect to the wound wire material, and further wound up so that the diameter gradually increases, and the wire material wound from the outside is superposed vertically with the small-diameter winding portion. Since the unwinding position of the unwinding wire 6 is unwound from both the left and right sides of the outer diameter from the large diameter position to the left and right. Unlike the conventional spiral shape as described above, the right and left balance of the biasing is not uneven, and the left and right deformation strengths are equalized because the left and right deformations are out of the large outer diameter position. Unwinding of the unwinding line 6 to the winding part 5 More biasing balance of the left and right becomes uniform if the corner left with substantially the same, thereby becomes possible to reduce it to flex up and down during the spring action.

  That is, since the winding part 5 which bends up and down at the time of a spring operation does not rub against an upper and lower member and is rubbed at the time of a slide, smooth operation is ensured and it becomes an unstable slide movement, or a slide movement is obstructed. It also has excellent durability.

  In addition, since both the unwinding wires 6 are unwound from the large outer diameter portion of the winding portion 5, not only the right and left biasing balance is equal, but also an increase in spring load can be expected. Even if the number of windings is the same, the structure can generate a large urging force, and this makes it possible to realize a large urging force more flatly.

  Further, since the spirally wound portions 5 that are reversely wound with each other are superposed in two upper and lower stages, and this is formed into a winding shape that is continuous with each other at the center, the upper and lower winding overlap intervals are set to 0 (zero). If so, the thickness of the elastic portion 3 (winding portion 5) can be accommodated to a thickness twice as large as the winding thickness, and the request for thinning can be sufficiently met.

  In addition, the two upper and lower spiral winding shapes that are reversely wound with each other are made symmetrical with the same shape as the reverse winding, and the unwinding angle of the unwinding line 6 is also the same, so that the right and left biasing balance is extremely good. The left and right deformation strength is uniform, there is almost no vertical deflection, and an extremely revolutionary elastic portion that can strengthen the urging force can be realized.

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

  The first embodiment shown in FIGS. 1 to 8 is slidably engaged between a slide portion as a guide portion 7 provided on the first member 1 and a slide guide portion as a guide portion 7 provided on the second member 2.

And a biasing force in the sliding direction between the first member 1 and the second member 2, that is, a return biasing (closed biasing) and a forward biasing (opening biasing). The elastic portion 3 is a flat shape having a connecting end 4 on the left and right sides and a winding portion 5 in the middle of the wire rod. So that the right and left connecting ends 4 are separated from each other so as to cause a widening bias. The other end is connected to one end of the binding edge 4 to the first member 1 are connected to the second member 2.

  Hereinafter, the present embodiment will be specifically described.

  In this embodiment, the main body part and the superposition part are superposed, and from this superposed state, the superposition part can be slid in the direction of the superposition surface to expose a part of the superposition face. In this way, the present invention is applied to an electronic device in which the main body and the overlapping portion are connected by a slide device. Specifically, the present invention is applied to a slide-type mobile phone, and numeric keys and function keys are used. A main body provided with arranged operation parts on the upper surface side is a first member 1, and a superposition part that slidably overlaps with the main part to open and close the operation part so as to be concealed and exposed is a second member 2. The member 2 is provided with a display unit such as a liquid crystal panel on which a predetermined display is made on the upper side surface, and the first member 1 and the second member 2 are slidably coupled to each other.

  In this embodiment, the second member 2 superposed on the first member 1 is slidably connected in the direction of the superposed surface via the guide portion 7 or, for example, as shown in FIG. In addition to the formula, the slide device is connected to be freely slidable in the direction of the overlapping surface. The slide device is disposed between the first member 1 and the second member 2 and has one end connected to the first member 1. The elastic part 3 whose other end is connected to the second member 2 and generates an urging force in the sliding direction is wound in the middle of the wire as described above, and has the connecting ends 4 on the left and right, and the winding part 5 in the middle. The first member 1 is connected to one end of the connecting end 4 so that the left and right connecting ends 4 are biased so as to be separated from each other. And the other end is connected to the second member 2.

  Further, until the second member 2 is slid by a predetermined length with respect to the first member 1, the second member 2 is moved by an angled biasing force in the sliding direction by the elastic portion 3 having a generally U-shape. A return urging force that moves back is generated, and when the slide member is slid for a predetermined length, a forward urging force that causes the second member 2 to move forward is generated.

  In other words, the overlapping surface of the first member 1 is exposed by sliding the second member 2 relative to the first member 1 from the overlapping state where the second member 2 covers and closes the first member 1. And the left and right connecting ends 4 of the elastic portion 3 are pressed in a direction approaching each other to connect one end of the connecting end 4 to the first member 1 and the other end The elastic member 3 is connected to the second member 2 so as to generate an expanded urging force that causes the connecting ends 4 to be separated from each other, and the expanded urging force generated at the left and right connecting ends 4 slides. During the sliding movement of the second member 2 to the sliding position with respect to the first member 1 at the boundary of the sliding position that does not act as a moving force, a closing bias is generated in the second member 2 by this widening bias, Slide it to a position beyond this slide position It is configured so as biased open by the expansion angle urging the second member 2 occurs.

  Further, as shown in FIG. 15, by providing this slide device even in the case of rotating and sliding, positioning bias is generated by rotating return bias at the rotating slide starting position (the slide opening position), and it is rotated 90 degrees. It may be configured such that the positioning bias is generated by the rotational advance bias at the rotational position where it slides and becomes T-shaped.

  The winding part 5 of the elastic part 3 which is the main part of the present invention is wound so that the diameter gradually becomes smaller, and further reversely so as to be polymerized in the thickness direction with respect to the wound wire. The wire is wound gradually so as to have a large diameter, and the wire wound from the outside has a small-diameter winding portion and an upper and lower polymerization portion that is vertically polymerized, and is unwound from the outside again.

  That is, the left and right unwinding wires 6 having the connecting end 4 at the tip, and the left and right unwinding wires 6 are connected to the left and right unwinding wires 6 so as to be positioned substantially in the same plane. The winding portion 5 is simply wound so that the diameter gradually decreases from the outside to the inside continuously connected to the base portion of the one winding wire 6. It does not have a configuration in which it reaches the center and goes out of the winding center and is connected to the base of the other winding 6, and the base of the one winding 6 is also connected to the other winding 6. The base is also configured to be connected to the outside of the winding part 5.

  Specifically, in the present embodiment, the coil is wound in a spiral shape so that the diameter gradually decreases from the outside to the inside, and is further polymerized with respect to the wound wire without going out at the center portion. The wire is wound in a spiral shape so that the diameter gradually increases toward the outside, and a flat spiral shape is formed so that the wire wound from the outside winds from the outside again. The unwinding angles are substantially the same, and the unwinding line 6 is configured to be substantially symmetrical with respect to the winding portion 5.

  The first embodiment shown in FIG. 1 to FIG. 8 is a shape in which the diameter gradually decreases from the outside (spiral shape), and when the vortex is wound twice inside, the wire is polymerized in the vertical direction. In addition, the spiral is wound twice so that the spiral gradually increases from the center, and the spiral is set to a shape that should be called a forward / reverse two-stage winding of the spiral from the outside to the center and from the center to the outside.

  In other words, in the configuration formed by winding one wire, the connecting end 4 is provided at the distal ends of the left and right unwinding wires 6 unwound from the winding portion 5, and the left and right unwinding wires are provided. 6 so that the diameter of each of the bases 6 is outward and the two are spirally wound in substantially the same plane so that both of them gradually become smaller in diameter so that they are continuously connected to each other at the center in the vertical polymerization state. The winding part 5 is formed by winding a single wire.

  In this embodiment and any of the following embodiments, the portion where the wire wound in the spiral shape of the winding portion 5 is vertically superposed does not become triple-wire polymerization but double-wire polymerization state in the vertical direction of the elastic portion 3. The thickness is configured in a flat shape that fits within a range of three times the thickness of the wire.

  In particular, in the present embodiment, the upper and lower thicknesses are configured to be exactly twice that of the wire as a configuration in which the gap between the overlapping wires is 0 (zero). That is, even if there is no gap between the wires, it is easy to keep at least three times the range as described above without leaving a gap more than the wire.

  Furthermore, in this embodiment, the winding part 5 provided between the winding lines 6 is formed so that the spiral parts that are opposite to each other are superposed vertically and symmetrically formed. The outside shape of each unwinding line 6 is also set symmetrically.

  Accordingly, the thickness of the elastic portion 3 (winding portion 5) can be accommodated twice as much as the winding thickness, and the request for thinning can be sufficiently met. By making the winding shape the same shape as the reverse winding and making it symmetrical, and the winding angle of the winding wire 6 is also the same, the left and right biasing balance is very good, the left and right deformation strength is even, and the vertical deflection is almost It will be possible to realize an extremely innovative elastic part that can increase the urging force.

  In the second embodiment shown in FIG. 9 to FIG. 11, the diameter of the small-diameter spiral portion on the inner side of the second winding of the first embodiment is not as small as that shown in the first embodiment, and the outer spiral portion of the first winding. It is the Example made into the diameter close | similar to the diameter of this.

  Further, in the third embodiment shown in FIGS. 12 to 14, the shape is swirled three times so that the diameter gradually decreases from the outside to the inside, whereas the first embodiment and the second embodiment have two turns. This is an example of three windings.

  In any of the embodiments, spirals that are reversely wound with each other are overlapped in two upper and lower stages, and are connected so as to cross at the center, and smoothly unwinds and winds so as to extend outward from the outermost diameter part of the spiral. The shape is formed so as to smoothly connect from the outside of the part 5 to the base part of the unwinding line 6.

  Furthermore, in other words, each of the embodiments is a two-stage inverted polymerization type spiral winding section 5 and also has a bilaterally symmetric shape and is approximately twice as thick as the wire, and within a thickness range approximately twice that of the wire. The left and right unwinding wires 6 are unwound from the outside without being unwound from the center while being spiral, and the unwinding wires 6 are formed in a right-and-left shape around the winding portion 5 in a predetermined shape. The shape is unwound at the same angle, and the left and right sides are completely symmetrical and has a uniform bias balance so that there is almost no vertical deflection during spring operation. The unwinding wire 6 has a large diameter on both sides. Since it winds out so that it may connect smoothly, it becomes a structure where a bending elastic force is large and a spring load increases compared with the case where it bends and winds at a steep angle from the center part.

  The present invention is not limited to the first embodiment, the second embodiment, and the third embodiment, and the specific configuration of each component can be designed as appropriate.
