Description

  The present invention, for example, a slide device in which a main body portion and a superposition portion are superposed and slidably moved in the superposition plane direction, and a superposition portion is slid from an occluded state where they are superposed to each other and opened. It relates to electronic devices such as telephones and mobile phones.

  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. 2. Description of the Related Art Conventionally, there is a slide type mobile phone having a structure in which a main body part and a superposition part are relatively moved in the front-rear direction.

  This is because the overlapping part is provided with a slide guide part (for example, a guide rail part) with an interval left and right, and slide parts that are slidably engaged with the left and right slide guide parts are provided on the left and right sides of the main body part. Thus, the sliding portion is relatively slid to connect the overlapping portion and the main body portion so as to be slidable.

  As described above, the slide device that realizes the slide structure of the slide-type mobile phone is configured such that the slide portions are slidably engaged between the slide guide portions provided on the left and right sides, and the slide guide portions are slidable. On the other hand, the first member and the second member are slidably coupled in the overlapping surface direction via a slide guide mechanism that slidably engages the slide portion.

  By the way, the slide type mobile phone using the slide device that slidably connects the main body part and the overlapping part as described above has a closed position (initial position) before the slide start in which the operation part of the main body part is concealed by the overlapping part. ) And the slide open position where the operation portion is exposed by sliding the front and rear direction so that the overlapping portion is displaced, and is configured to hold and hold (close bias, open bias or click engagement). Is desirable.

  Therefore, for example, as in Patent Document 1, one end of each of the two torsion springs is connected to each of the left and right sides of the first member, and the other ends of the two torsion springs are connected to the left and right sides of the second member. Are connected so that a sliding movement biasing force is generated by an elastic biasing force generated in a direction separating one end and the other end of each of the two torsion springs. There is a slide device that is configured to be able to close and bias the second member to the closed position, or to open and bias the slide to the slide open position.

  Further, for example, as in Patent Document 2, a cam portion having a cam surface in the sliding movement direction is provided on the first member or the second member, and the cam contact that abuts the cam surface of the cam portion on the second member or the first member. When a cam moving part having a contact part is provided and urging means for pressing and urging the cam abutting part of the cam moving part toward the cam surface is provided, and when the second member slides relative to the first member The cam moving portion slides and moves while the cam contact portion of the cam moving portion comes into contact with the cam surface of the cam portion while being pressed and biased, and the cam contact portion of the cam moving portion is moved by the pressing force. A sliding movement biasing force is generated by the cam biasing force to move from the convex portion to the concave portion of the cam surface, and the second member is closed at the closed position with respect to the first member by the sliding movement biasing force, for example. Energizing or slurping It is configured to slide device so as to urge the positioning holding the biased open to de open position.

  Thus, the slide device that positions and holds and urges the second member relative to the first member by the slide movement urging force, for example, without providing a complicated positioning mechanism at the closed position (initial position) or the slide open position, for example, torsion Positioning and holding can be easily realized by providing a spring or setting the shape of the cam surface of the cam portion.

  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.

  In the present invention, the cam part 4 and the roller guide part 6 are provided in either of the first member 1 and the second member 2 slidably connected in the direction of the overlapping surface via the slide guide mechanism 3, and the cam moves For example, a configuration in which the cam member 4 and the roller guide portion 6 are provided in the second member 2 and the cam moving portion 5 is provided in the first member 1 as in the illustrated embodiment. Explained.

  When the second member 2 is slid relative to the first member 1, a sliding movement biasing force is generated by a cam biasing force.

  Therefore, for example, when the second member 2 is set to the slide open position with respect to the first member 1, the slide movement biasing force in the opening direction is generated, and the second member 2 is positioned and held biased at the slide open position. Designed to be able to achieve positioning and hold, such as configured to be able to slide open with a light force within a predetermined slide movement range, or to be configured to automatically slide open and move in some cases Therefore, it is possible to realize a configuration having various functions by urging the slide movement.

  Specifically, as in the illustrated embodiment described later, the second member 2 has a cam portion 4 having a cam surface 4a that is formed in the slide movement direction and undulates in the left-right direction perpendicular to the slide movement direction. On the other hand, the first member 1 is provided with a cam moving part 5 having a cam roller body 5A that abuts on the cam surface 4a of the cam part 4, and the second member 2 with respect to the first member 1 is provided. The cam moving part 5 slides while the cam roller body 5A of the cam moving part 5 is pressed and urged against the cam surface 4a of the cam part 4 by the urging force of the urging means S. The cam roller body 5A of the cam moving portion 5 is urged to move from the convex portion of the cam surface 4a to the concave portion, thereby generating a sliding movement urging force of the second member 2 against the first member 1. Configured as There.

  Therefore, the generation range, strength, direction, and the like of the sliding movement urging force by the cam urging force can be appropriately designed by setting the cam shape of the cam surface 4a of the cam portion 4 provided on the second member 2.

  In the present invention, the cam roller body 5A of the cam moving portion 5 of the first member 1 is biased toward the cam surface 4a of the cam portion 4 formed along the slide moving direction on the left and right sides of the first member 2. Since the pressing force is applied by the means S, the first member 1 is pressed and biased to the left and right by the reaction force of the pressing force. There is a concern that the member 2 may be shifted to the left or right side, or an excessive slide resistance may be generated.

  However, in the present invention, the second member 2 is provided with a roller guide portion 6 having a guide flat surface 6a formed along the sliding movement direction at a position facing the cam surface 4a of the cam portion 4 of the second member 2. On the other hand, the cam moving part 5 of the first member 1 is not only the aforementioned cam roller body 5A abutting against the cam surface 4a, but also two bodies abutting against the guide flat surface 6a of the roller guide part 6. The guide roller bodies 5B and 5B are configured such that the cam roller body 5A can be contacted and separated in the left-right direction perpendicular to the sliding movement direction with respect to the two guide roller bodies 5B and 5B, and the cam roller body 5A. Is provided with a biasing means S that generates a biasing force in a direction away from the two guide roller bodies 5B and 5B.

  Accordingly, when the second member 2 is slid relative to the first member 1, the cam roller body 5 </ b> A of the cam moving portion 5 is pressed and urged against the cam surface 4 a of the cam portion 4 by the urging force of the urging means S. At the same time, the two guide roller bodies 5B, 5B of the cam moving portion 5 are brought into contact with the guide flat surface 6a of the roller guide portion 6 while being pressed. That is, since the two guide roller bodies 5B and 5B of the first member 1 are always pressed and urged against the guide flat surface 6a of the roller guide portion 6 of the second member 2, the guide flat surface 6a is so-called. It becomes a positioning reference plane, and the relative positional relationship in the left-right direction between the first member 1 and the second member 2 is reliably prevented from shifting to the left or right side. At the same time, a total of three points of the cam roller body 5A of the cam moving portion 5 of the first member 1 and the two guide roller bodies 5B and 5B come into contact with the cam surface 4a and the guide flat surface 6a of the second member 2. Therefore, rattling is also reliably prevented.

  Further, as described above, since the left and right sides are not displaced, it is possible to prevent an excessive slide resistance from occurring, the cam roller body 5A rolls with respect to the cam surface 4a, and the guide roller body with respect to the guide flat surface 6a. Since 5B and 5B roll, slide resistance due to sliding friction does not occur on the cam surface 4a and the guide flat surface 6a. Therefore, the present invention can realize an extremely smooth operation feeling during sliding movement.

  Further, in the present invention, the cam surface 4a of the cam portion 4 is formed only on the left and right sides of the second member 2, and the one-side cam in which the guide flat surface 6a of the roller guide portion 6 is formed at the opposite position and the cam surface 4a is not formed. Since the cam structure of the surface 4a is employed, there is a sufficient space for providing the cam moving part 5 and the like. Further, since the space for forming the cam surface 4a on one side is wide, the degree of freedom in setting the cam shape of the cam surface 4a is high.

  Therefore, it can be said that the structure is suitable for designing various cam shapes of the cam surface 4a according to the required generation range, direction, strength, etc. of the slide movement biasing force, and has a higher commercial value as described below, for example. The cam surface 4a having various cam shapes can be easily designed and realized.

  That is, for example, as in an embodiment described later, the cam surface 4a of the cam portion 4 is a cam roller body of the cam moving portion 5 at the closed position before the slide where the second member 2 overlaps the first member 1. The slide guide mechanism 3 has a cam shape having an engaging recess 7 for positioning and engaging 5A so that the second member 2 can be slid open in any of the front and rear directions with respect to the first member 1 from the closed position. And the cam surface 4a of the cam portion 4 returns from the engaging recess 7 to the front and rear sliding directions in the direction of the front and rear sliding movements, with the engaging recess 7 as a valley. When the second member 2 slides forward and backward from the closed position with respect to the first member 1, the cam roller body 5 of the cam moving portion 5 is moved until it slides a predetermined length. Is configured to generate a sliding movement biasing force in the return direction toward the closed position by being pressed and biased to the return biasing inclined surface portion 8. In addition to the normal slide movement operation that slides forward from the closed position (initial position) before the start of the slide where the slides 2 are overlapped, the second member 2 can also be slid open from the closed position to the rear. The use application of the electronic device to which the invention is applied can be expanded, and there is no fear that the second member will fluctuate with respect to the first member in the closed position (initial position) due to the slide biasing force due to the cam biasing force. The operability and functionality can be easily designed so that the positioning holding force can be exerted by the sliding movement biasing force even at the front and rear slide opening positions as in the examples described later. So that the electronic device can be realized with a high revolutionary sliding device and sliding device of Xiu more commercial value was.

  For example, the main body part A provided with the operation part and the superposition part B provided with the display part are superposed and arranged, and the superposition part B is slid with respect to the superposition surface with respect to the main body part A to The main body portion and the overlapping portion are connected by a slide device so that a part or the whole can be exposed. In this slide device, the main body portion A is the first member 1 or the second member 2, and the overlap When the slide device of the present invention in which the part B is the second member 2 or the first member 1 is used, it slides forward from the closed position (initial position) where the overlapping part B is overlapped with the main body part A. An operation unit is provided on the upper surface of the main body A exposed by opening and moving, and a portion exposed by sliding open backward is, for example, a second operation unit, a second display unit, and camera photography. Various functions such as For example, as illustrated in FIG. 5, if the camera photographing unit is provided in a portion exposed by the rearward slide opening movement, the overlapping portion B is moved backward with one hand holding the main body portion A. The camera shooting part can be exposed by sliding it to the top, and the camera lens can be opened easily with one hand. The operability and functionality are further improved, and a high sales promotion effect can be achieved with a novel operation style. An epoch-making slide device and an electronic apparatus using the slide device are obtained.

The body 5A is configured so as to be able to contact and separate in the left-right direction with respect to the two guide roller bodies 5B and 5B, and the cam roller body 5A and the two guide roller bodies 5B and 5B are arranged in a direction to be separated from each other. The biasing means S for biasing the movable member 11 is provided.

  In this embodiment, as shown in FIG. 6, the slide guide portion forming plate 13 </ b> A attached and fixed to the upper surface portion of the first member 1 is also used as the base portion of the cam moving portion 5.

  As shown in FIG. 6, the upper surface side (the first member 1 and the first member 1 and the base portion of the cam moving portion 5 is positioned close to the slide guide portion 13 provided on the left and right end sides of the slide guide portion forming plate 13A. Two guide rollers 5B and 5B are coupled to the second member 2 via a roller mounting shaft member 16 in a tandem state in a slidable direction along a slide movement direction. Reference numeral 16a in the figure denotes a screwing member 16a for screwing and fixing the roller mounting shaft member 16 to the cam moving part 5.

  On the other hand, the cam roller body 5A is placed on the upper surface side through the movable member 11 at a position close to the slide guide portion 13 provided on the left and right other ends of the slide guide portion forming plate 13A as the base portion of the cam moving portion 5. Provided. Specifically, the movable guide hole 15 having a long and long hole shape as shown in FIGS. 6 and 7 is formed at two locations on the base portion (slide guide portion forming plate 13A) of the cam moving portion 5. Then, an L-shaped movable member 11 is connected to the upper surface side of the base portion of the cam moving portion 5 by a pin member 11a inserted through the movable guide hole 15, and the pin member 11a moves in the movable guide hole 15. The movable member 11 is configured to be movable relative to the cam moving unit 5 in the left-right direction within a possible range.

  A cam roller body 5A is provided at one end (tip) of the L-shaped movable member 11 so as to be rotatable about the pin member 11a. On the other hand, as shown in FIGS. 6 and 8, one end of a plurality of tension springs 17 is connected to the other end (base end) of the movable member 11, and each other end of the plurality of tension springs 17 is A plurality of tension springs 17 are juxtaposed in tension between the cam moving part 5 and the movable member 11 in connection with the cam moving part 5. As shown in FIG. 8, when the first member 1 and the second member 2 are slidably connected to each other, the cam surface 4a of the cam portion 4 and the tip of the movable member 11 of the cam moving portion 5 are connected. The cam roller body 5A, the connecting part between the tension spring 17 and the base part (slide guide part forming plate 13A) of the cam moving part 5 and the connecting part between the tension spring 17 and the base end of the movable member 11 of the cam moving part 5 are sequentially left and right. The connecting positions of both ends of the tension spring 17 are set so as to line up in the direction.

  Accordingly, as shown in FIG. 8, the movable member 11 is pulled toward the cam surface 4 a of the cam portion 4 by the tensile elastic force of the plurality of tension springs 17. The cam roller body 5A is pressed and urged toward the cam surface 4a of the cam portion 4.

  That is, the plurality of tension springs 17 arranged in parallel are configured as the biasing means S.

  As this urging means S, there is an urging force for separating the cam roller body 5A provided on the movable member 11 and the two guide roller bodies 5B of the cam moving portion 5 from each other in the left-right direction perpendicular to the sliding movement direction. As long as the structure is generated, various structures such as a structure using an anti-compression spring can be adopted. However, in the case of the structure in which the cam roller body 5A is pressed and urged against the cam surface 4a by the tensile elastic force of the tension spring 17 as in this embodiment, for example, The compression spring does not require an essential spring shaft, and has the advantage that the number of parts is small and the mass productivity and cost are excellent.

  In FIG. 6, reference numeral 11a designates the movable member 11 for attaching the cam roller body 5A to the distal end of the movable member 11 and connecting one end of the tension spring 17 to the proximal end of the movable member 11 as shown in FIG. An attachment cover body 11A attached to the upper surface side.

  Further, as shown in FIG. 6, the cam portion 4 and the roller guide portion 6 provided in the second member 2 form a guide hole 10 having a length in the sliding movement direction in the cam forming plate body 12. A part of the hole edge of the guide hole 10 of the forming plate 12 is configured as a cam surface 4a of the cam portion 4 that undulates in the horizontal direction and a guide flat surface 6a of the roller guide portion 6 that is flat along the slide movement direction. is doing. Specifically, the cam forming plate portion 12 is configured by punching a metal flat thin plate (sheet metal) with a long hole-shaped guide hole 10 as shown in FIG.

  Then, as shown in FIG. 9, the cam forming plate portion 12 is attached and fixed to the lower surface side (the overlapping surface side with the first member 1) of the second member 2 (the overlapping portion B). 2 is provided with a cam portion 4 and a roller guide portion 6.

  Accordingly, since the hole end surface (groove edge) of the guide hole 10 simply formed by pressing in the sheet metal is used as the cam surface 4a of the cam portion 4 and the guide flat surface 6a of the roller guide portion 6, this cam portion. 4 and the roller guide portion 6 can be formed on the cam forming plate portion 12 simultaneously and easily.

  As shown in the figure, in the present embodiment, the above-described slide shafts 14B are provided at both the left and right ends of the cam forming plate portion 12, and therefore the cam forming plate portion 12 also serves as the above-described slide portion forming plate 14A. It is.

  Further, as shown in FIGS. 6 and 8, the guide flat surface 6a of the roller guide portion 6 is formed in parallel with the slide movement direction and flat.

  The cam surface 4a of the cam portion 4 has an engagement recess 7 for positioning and engaging the cam roller body 5A of the cam moving portion 5 at the closed position before the slide start where the second member 2 overlaps the first member 1. The cam shape.

  Specifically, as illustrated in FIG. 1, the overlapping portion B serving as the second member 2 with respect to the main body portion A serving as the first member 1 is overlapped with the overlapping position where the entire overlapping surface of the main body portion A is covered. The cam surface of the cam portion 4 of the second member 2 in which the cam roller body 5A of the cam moving portion 5 provided in the first member 1 is positioned and engaged at the closing position (initial position) before the slide starts. In the predetermined position 4a, the engaging recess 7 is formed in which the cam roller body 5A falls and engages.

  The slide guide mechanism 3 has a slide movement range so that the second member 2 (overlapping part B) can be slid open in any direction from the closed position to the first member 1 (main part A). It is set.

  In the present embodiment, as shown in FIGS. 1 to 4 and 8, the movable range when the overlapping portion B is slid forward from the closed position so as to expose the operation portion of the main body A is exposed. Is set to be longer than the movable range when the overlapping portion B is slid open from the closed position to the rear (at least twice as long as the movable range of the slide open movement to the rear). is doing.

  This is the operability during the operation of sliding the overlapping part B back and forth from the closed position with the thumb of one hand holding the main body part A (the pushing slide opening operation to the front can be performed without a sense of incongruity, but the rearward movement The slide opening operation is difficult to perform in a long range) and, like a general mobile phone, the upper surface of the main body A exposed by sliding open the overlapping portion B from the closed position to the front (overlapping) The main operation part is provided on the surface), and the part exposed by sliding backward to the rear is the camera photographing part 18 described later, for example, the second operation part, the second display part, etc. Considering the provision of a typical (auxiliary) functional unit, the movable range of the forward slide opening movement is set longer than that of the rear.

  Further, the cam surface 4a of the cam portion 4 has a cam shape in which the engaging concave portion 7 is used as a trough portion, and the biased inclined surface portion 8 is formed by returning from the engaging concave portion 7 to the forward and backward sliding directions. It is said. Specifically, as shown in FIG. 8, the cam surface 4 a is formed in a V shape with the engaging recess 7 as a trough (valley bottom), and each of the engaging recess 7 is moved in the front-rear slide movement direction. A return biasing inclined surface portion 8 having an upward inclined surface shape is provided.

  Therefore, when the second member 2 (overlapping part B) slides forward and backward from the closed position with respect to the first member 1 (main part A), the cam roller body of the cam moving part 5 until the predetermined length slides. 5A comes into contact with the return bias inclined surface portion 8 while being pressed and biased, and a cam bias force that tries to move from the convex portion to the concave portion generates a slide moving bias force in the return direction toward the closed position. That is, the first member 1 and the second member 2 are urged so as to be in a closed state unless they slide for a predetermined length, and are positioned and urged to a closed position without fluttering.

  Further, the cam surface 4a of the cam portion 4 advances in a downward inclined surface shape from a predetermined slide intermediate position between the closed position and the slide open position which is the slide movement end position to the slide open position, and the biasing inclination. The cam portion is formed with a surface portion 9.

  Accordingly, when the second member 2 (overlapping part B) is slid open from the closed position to the first member 1 (main body part A), the second member 2 is slid open to the predetermined slide intermediate position. The cam roller body 5A of the cam moving part 5 abuts while being pressed and urged against the advance urging inclined surface part 9, and the cam urging force to move from the convex part to the concave part advances toward the slide opening position. The sliding movement biasing force is generated.

  Specifically, as shown in FIG. 8, the cam surface 4 a of the cam portion 4 is located at the top position of each return urging inclined surface portion 8 formed in the forward / backward slide movement direction from the engagement recess 7 (ie, for example, In the case of the forward slide opening movement, the forward biasing inclined surface portion 9 having a downward inclined surface shape is formed in the range from the upward inclined top portion of the return biasing inclined surface portion 8 shown in FIG. It has a cam shape.

  Accordingly, when the second member 2 (overlapping portion B) is slid open from the closed position with respect to the first member 1 (main body portion A), the cam roller body 5A of the cam moving portion 5 is moved toward the cam surface 4a. Until a predetermined length of slide movement that passes through the return bias inclined surface portion 8 (for example, to the slide position in FIG. 2), a slide movement biasing force in the return direction is generated toward the closed position. When the lever roller 5A slides and moves to a position where the cam roller body 5A contacts the advance biasing inclined surface 9 of the cam surface 4a, a slide movement biasing force in the advance direction is generated toward the slide release position. .

  That is, if the overlapping portion B is slid by a predetermined length against the return bias from the closed position in one of the front and rear directions with the thumb of one hand holding the main body A, the polymerization is performed by the forward bias thereafter. Part B is configured to automatically open to the front and rear slide opening positions.

  In addition, in the slide range from the closed position to the front and rear slide release positions, the slide movement biasing force in either the return direction or the advance direction is generated. Thus, the second member 2 does not flutter back and forth.

  Further, as shown in FIGS. 3 and 4, when the slide movement of the first member 1 to the front and rear slide release positions is performed, the cam roller body 5A of the cam moving unit 5 is just advanced in the downward inclined surface shape. It is configured to be held at the valley bottom of the urging inclined surface portion 9 or to be in the middle of falling down the inclined surface toward the valley bottom of the advanced urging inclined surface portion 9 (in this embodiment, the cam roller at the slide open position) The body 5A is just advanced and is held at the bottom of the valley of the biasing inclined surface portion 9), and the second member 2 is positioned and held at the front and rear slide open positions with respect to the first member 1, respectively. It is configured.

  Also, as shown in FIG. 3, the operation part provided on the overlapping surface of the main body part A is exposed by sliding open the overlapping part B forward with respect to the main body part A. On the other hand, as shown in FIG. 4, the camera photographing unit as shown in FIG. 5 is formed on the lower surface (overlapping surface) of the overlapping part B exposed by sliding and moving the overlapping part B backward with respect to the main body part A. 18 (camera lens and flash light emitting unit) is provided, and the camera photographing unit 18 is exposed by the slide opening movement to the rear so that camera photographing can be performed.

  In this embodiment configured as described above, as shown in FIGS. 1 to 4, when the main body part A and the overlapping part B are slid, the cam movement of the main body part A is performed by the tensile elastic force of the tension spring 17. The cam roller body 5A of the portion 5 abuts against the cam surface 4a of the cam portion 4 while being pressed and urged, abuts along the unevenness of the cam surface 4a and rolls while moving in the left-right direction. The two guide roller bodies 5B and 5B provided on the roller 5 are pressed and urged against the guide flat surface 6a of the roller guide portion 6 and roll while always abutting against the guide flat surface 6a. That is, as shown in FIG. 8, a total of three points of the cam roller body 5A and the two guide roller bodies 5B and 5B of the cam moving unit 5 are in contact with the cam surface 4a and the guide flat surface 6a to support the three points. As a result, the cam moving part 5 cannot be rattled at all. Further, the two guide roller bodies 5B, 5B provided in the positioning state on the cam moving portion 5 are always in contact with the guide flat surface 6a during the slide movement, and the guide flat surface 6a serves as a positioning reference surface. It is possible to reliably prevent the overlapping portion B from being shifted to the left or right with respect to the main body portion A.

  Therefore, a deviation that the display part of the overlapping part B is displaced to the left or right with respect to the main part A cannot occur, and the deviation between the slide guide part 13 and the slide part 14 of the slide guide mechanism 3 is not caused. In addition, it is possible to reliably prevent the occurrence of excessive slide resistance and to realize an extremely smooth operation feeling.

  Moreover, as illustrated in FIGS. 1 to 4, the first member 1 (main part A) is moved forward from the closed position (initial position) before the start of sliding where the second member 2 (overlapping part B) is overlapped. In addition to the normal slide operation to move the slide open, the second member 2 can also slide open from the closed position to the rear, so that the usage can be expanded as a device and the slide biasing force by the cam biasing force. Therefore, there is no fear that the second member 2 will fluctuate with respect to the first member 1 in the middle of the slide, and an excellent slide device that can be reliably positioned and held at the closed position and the front and rear slide open positions. It becomes an electronic device using.
