Description

  The present invention relates to a portable electronic device such as a cellular phone or a portable information terminal, and more particularly to a slide operation component used for a casing of a cellular phone, a photographing unit or the like, and a slide-type portable electronic device using the same. is there.

  A portable electronic device such as a cellular phone is carried by a user even when not in use. Therefore, the portable electronic device is required to be portable and downsized. On the other hand, when the area of an operation unit such as a key switch or a display unit is reduced by downsizing, there is a problem that operability is deteriorated. For this reason, most mobile phones are of the folding type in which the display unit is folded and stored on the operation unit, but recently, some models have a display that overlaps the operation unit. It is a slide type in which the operation part is exposed by shifting the parts in parallel. In this slide-type mobile phone, a slide module is used to perform a slide operation from a closed state in which the display unit is closed to an open state in which the display unit is shifted to expose the operation unit (for example, Patent Document 1). ).

However, the conventional slide-type mobile phone needs to be pressurized over the entire length of the slide distance when the user performs the slide operation, especially when a woman with a small hand operates with one hand. It makes me feel inconvenient. For this reason, among conventional slide type mobile phones, for example, a slide module using an elastic member such as a torsion spring is mounted, and a slide assisting force is generated in both opening and closing directions to improve convenience.

In such a slide module, for an elastic member such as a torsion spring, simultaneously with a sliding assist force, a holding load for holding the open state and the closed state, and an open state to a closed state, or a closed state to an open state It played a role to realize the escape load to change the state. However, the maximum load by the torsion spring must be determined according to the largest force among the sliding assist force, holding load, and escape load, and in order to increase the maximum load of the torsion spring while maintaining reliability. In general, the spring wire diameter, spring coil diameter, etc. must be increased. For this reason, the thickness, width, and height of the mobile phone have increased, and there has been a problem that the slide distance cannot be increased.

The present invention has been made to solve the above-described problems, and can be easily opened and closed in both directions with one hand, and can be miniaturized slides that maintain a stable state in an open state and a closed state. An object is to obtain an operating component and a portable electronic device using the same.

  The slide operation component according to the present invention includes a first member and a second member that slides between a first position and a second position with respect to the first member in a state where the first member is overlapped. And both ends of the first member and the second member are fixed to each other, and when the pressing force acting on the first member toward the first position exceeds a predetermined value, the first member A slide assisting force toward the first position is applied to the first member, and when the pressing force toward the second position by acting on the first member exceeds a predetermined value, the first member moves toward the second position. An elastic member for applying a sliding assist force to the first member, and a push in the direction of the first position applied between the first member and the second member. When the pressure does not exceed a predetermined value, the first member is locked at the first position, A first locking portion that releases the locked state of the first member and allows the first member to slide in the first position direction, the first member, When the pressing force provided between the second member and applied to the first member toward the second position does not exceed a predetermined value, the first member is engaged with the second position. And when the predetermined value is exceeded, a second locking portion that releases the locking state of the first member and allows the first member to slide in the second position direction is provided. It is provided.

  The present invention provides a sliding operation component that performs sliding operation, and the opening / closing function is realized by realizing the holding load and escape load functions among the functions of the slide assisting force, the holding load, and the escape load, which were performed by the elastic member. The sliding operation in both directions can be facilitated, and a slide operation component that can be miniaturized to maintain the open state and the closed state, and a portable electronic device using the slide operation component can be obtained.

Hereinafter, a case where the present invention is applied to a slide type mobile phone will be described as an example.
Embodiment 1 FIG.
FIG. 1 is an exploded perspective view of a slide-type mobile phone according to Embodiment 1 of the present invention. In FIG. 1, the mobile phone 1 is provided with a display unit 3 for displaying characters, images, and the like on a first housing 2. The first casing 2 is disposed on an upper portion of a second casing 5 having an operation unit 4 including various key switches for character input, power supply switching operation, and the like. The first casing 2 is fixed to a slide rail 6 as a first member by screws or adhesion, and the second casing 5 is a second slide that slides in a state where the slide rail 6 is overlapped. It is fixed to the guide rail 7 which is a member by screws or adhesion. As a result, the first casing 2 slides back and forth in the longitudinal direction of the second casing 5 while being disposed on the second casing 5.

FIG. 2A is a front view of the slide module 8 constituted by the slide rail 6 and the guide rail 7. (B) represents a cross section between dotted lines AA in the front view. In FIG. 2, a pair of annular holes a and b are formed at both ends of a torsion spring 9 which is an elastic member that gives a sliding assist force. On the guide rail 7, pins c and d are fixed upright. The pin c passes through the hole a at the end of the torsion spring 9, and the pin d passes through the hole b. The torsion spring 9 is provided so as to be rotatable with respect to the pins c and d. The torsion spring 9 is arranged such that its torsion angle is minimized during the sliding operation of the first housing 2, and is configured so that a sliding assist force in both the opening and closing directions acts. .

The guide rail 7 is provided with a spring 10 that is a locking member of the first locking portion that is given an elastic force by cutting and raising a part thereof. And the latch which is a 1st latching | locking part is comprised by pairing with the processus | protrusion 11 which is a to-be-latched member of the 1st latching | locking part comprised by raising a part of slide rail 6. As shown in FIG. Thereby, the slide rail 6 is locked at the first position with respect to the guide rail 7. The first position is a closed state in which the operation unit 4 is protected in a state where the first housing 2 covers the second housing 5. Similarly, the spring 10 that also functions as a locking member of the second locking portion and a protrusion 12 that is a locked member of the second locking portion formed by raising a part of the slide rail 6 are paired. Thus, a latch which is the second locking portion is configured. As a result, the slide rail 6 is locked at the second position with respect to the guide rail 7. The second position is an open state in which the second casing 5 is opened and the operation unit 4 is exposed, and the user can use the mobile phone 1.

Next, the operation will be described.
3 to 16 are views for explaining the opening / closing operation of the slide rail 6 and the first housing 2. In FIG. 3, the right torsion spring is omitted. 3A to 16A are front views of the mobile phone 1 of the present invention, FIG. 3B is a right side view thereof, and FIG. 3C is a front view of the slide module 6 inside the mobile phone 1 of the present invention. (D) is a right side view thereof.

First, an operation for changing the first casing 2 of the cellular phone 1 from the closed state to the opened state will be described. FIG. 3 shows that the first casing 2 of the mobile phone 1 of the present invention is locked to the second casing 5 in the first position, that is, the position in the closed state. In this state, a holding force (holding load) having a predetermined value is generated by fitting the spring 10 of the slide module 8 and the protrusion 11. Accordingly, the slide module 8 provided with the spring 10 and the protrusion 11 and the first casing 2 and the second casing 5 are fixed to each other, so that the first casing 2 and the second casing 5 are fixed. The closed state can be maintained with the housing 5. In this state, the torsion angle X of the torsion spring 9 is maximized. When a pressing force F is applied to the first casing 1 in this state, the closed state is maintained when the pressing force F is smaller than the holding force between the spring 10 and the protrusion 11.

Next, when a pressing force F exceeding the holding force is applied to the first housing 2, the fitting between the spring 10 and the protrusion 11 is released, and by applying a larger pressing force F, the fitting is performed. The first housing 2 and the second housing 5 are completely out of the closed state by being completely displaced. This pressing force is a de-output (escape load), and FIG. 4 shows a state in which this closed state is escaped. In this state, the torsion angle of the torsion spring becomes smaller than in the state of FIG. This is because the force is accumulated in the torsion spring 9 from the state of FIG.

When the pressing force F is further applied from this state, the torsion angle X of the torsion spring is further reduced as shown in FIG. When a pressing force F is further applied, the holes a and b at both ends of the torsion spring are arranged in a line on the wavy line P as shown in FIG. In this state, the torsion angle X of the torsion spring is minimized. Further, the spring 10 is located at a position just between the protrusion 11 and the protrusion 12. In this state, the force stored in the torsion spring 9 is maximized.

Next, when a pressing force F is further applied from this state, the pins c and d provided on the guide rail 7 and the surface of the slide rail 6 on the guide rail 7 side, and holes a at both ends of the torsion spring 9 are provided. , B rotates to release the force stored in the torsion spring 9 until now. This force becomes a slide assist force, and the slide module 8 can be moved in the direction of the arrow only by the force f of the torsion spring 9 without requiring a pressing force. This state is the state shown in FIG.

Further, when the first housing 2 is slid in the direction of the arrow by the sliding assist force f of the torsion spring 9, the spring 10 of the slide module 8 and the protrusion 12 come into contact with each other. This state is shown in FIG. Furthermore, the sliding assist force f of only the torsion spring 9 is applied, and the protrusion 12 gets over the spring 10 so that the protrusion 12 and the spring 10 are fitted. This state is shown in FIG. In this state, a holding force having a predetermined value between the protrusion 12 and the spring 10 is applied by the fitting, so that the casing 2 of the mobile phone 1 is locked at the second position, that is, an open state. It becomes. In this state, the operation unit 4 is completely exposed and the mobile phone 1 can be operated. In this state, the torsion angle X of the torsion spring 9 is the maximum angle.

Next, an operation for changing the first casing 2 of the cellular phone 1 from the open state to the closed state will be described. As shown in FIG. 10, this time, a pressing force F is applied to the first housing 2 to push the first housing 2 toward the first position. In this state, the spring 10 of the slide module 8 and the protrusion 12 are fitted to generate a holding force having a predetermined value. Accordingly, the slide module 8 provided with the spring 10 and the protrusion 12 and the first casing 2 and the second casing 5 are fixed to each other, whereby the first casing 2 and the second casing 2 are fixed. The housing 5 can hold this open state. In this state, the torsion angle X of the torsion spring 9 is maximum. Next, when a pressing force F is applied to the first housing 1 in this state, the closed state is maintained when the pressing force F is smaller than the holding force having a predetermined value between the spring 10 and the protrusion 12. Be drunk.

Next, when a pressing force F exceeding the holding force is applied to the first housing 2, the fitting between the spring 10 and the protrusion 12 is released, and by applying a larger pressing force F, the fitting is performed. The first casing 2 and the second casing 5 are completely out of the open state by being completely displaced. This force is the output power. FIG. 11 shows that this open state has been escaped. In this state, the torsion angle X of the torsion spring 9 becomes smaller than in the state of FIG. This indicates that force is accumulated in the torsion spring 9 from the state of FIG.

When the pressing force F is further applied in this state, the torsion angle X of the torsion spring is further reduced as shown in FIG. When a pressing force F is further applied, the holes a and b at both ends of the torsion spring are arranged in a line on the wavy line P as shown in FIG. In this state, the angle X of the torsion spring 9 is minimized. Further, the spring 10 is located at a position just between the protrusion 11 and the protrusion 12. In this state, the force stored in the torsion spring is maximized.

Next, when a pressing force F is further applied from this state, the torsion spring 9 rotates with respect to the pins c and d, so that the force accumulated in the torsion spring 9 until now is released. This force becomes a slide assist force, and the slide module 8 is moved in the direction of the arrow only by the force f of the torsion spring 9 without requiring a pressing force. This state is shown in FIG.

Further, when the first housing 2 is slid by the sliding assist force f of the torsion spring 9 alone, the spring 10 of the slide module 8 and the protrusion 11 come into contact with each other. This state is shown in FIG. Further, the sliding assist force f of only the torsion spring 9 is applied, and the protrusion 11 gets over the spring 10 so that the protrusion 11 and the spring 10 are fitted. This state is shown in FIG. In this state, a holding force having a predetermined value acts between the protrusion 11 and the spring 10 by the fitting, so that the casing 2 of the mobile phone 1 is locked at the first position, that is, the closed state. It becomes. In this state, the operation unit 4 is overlapped by the first housing, and the operation unit of the mobile phone 1 can be protected. In this state, the torsion angle of the torsion spring 9 is the maximum angle.

  Next, FIG. 17 is a graph showing a relationship between a slide load that is a pressing force applied to the first housing 2 and a slide amount that is a distance that the first housing 2 slides. A characteristic curve 1 shows values in the conventional slide module, and a characteristic curve 2 shows values in the first embodiment. In FIG. 17, the horizontal axis represents the slide amount and the vertical axis represents the slide load. When the slide amount is Xmin, the closed state is indicated. When Xmax is indicated, the open state is indicated. X1 indicates the position where the direction of the slide load is reversed. In FIG. 17, Y1 is a holding load generated by the holding force of the first locking portion. When a load equal to or less than Y1 is applied in the sliding direction of the slide rail 6, the sliding operation is not started and a stable state is obtained. . Y2 is an escape load. When the slide rail is slid from the Xmin position in the closed state to the Xmax position in the open state, a load equal to or greater than Y2 is required. Then, when the slide is performed for X1 or more, a sliding assist force f is generated.

  In FIG. 17, in the characteristic curve 2, the holding force in the open state or the closed state is obtained between Xmin and X2 and between X3 and Xmax by the resultant force of the force by the latch structure and the sliding assist force f by the torsion spring 9 Escape load is realized. As a result, the torsion spring 9 that realizes the sliding assist force f of the characteristic curve 2 does not need to consider the holding force and the escape load. Therefore, the maximum load of the torsion spring 9 realizes the sliding assist force f of the characteristic curve 1. This can be realized with a load smaller than that of the torsion spring 9, and the restriction on the shape of the torsion spring 9 is reduced and the size can be reduced.

Next, the correspondence between the diagram for explaining the opening / closing operation of the slide module 8 and the first housing 2 of FIGS. 3 to 9 described above and the graph of FIG. 17 will be shown. First, the state of FIG. 3, that is, the closed state corresponds to the point that the slide load is Y1 or less and the slide amount is Xmin in FIG. The state of FIG. 4, that is, the state of exiting from the closed state corresponds to the point in FIG. 17 where the slide load exceeds Y2 and the slide amount becomes X2. The state of FIG. 5 corresponds to a point where the slide amount of FIG. 17 is approximately in the middle between X2 and X1. Next, the state of FIG. 6, that is, the state in which the sliding assist force is reversed corresponds to the case of FIG. The state of FIG. 7 corresponds to a point where the slide amount of FIG. 17 is approximately in the middle between X1 and X3. The state of FIG. 8, that is, the state immediately before the open state corresponds to the point where the slide amount is X3 in FIG. The state of FIG. 9, that is, the open state, corresponds to the point where the slide amount is Xmax in FIG.

  As described above, the cellular phone 1 according to the first embodiment has different functions of the holding load and the escape load among the slide assisting force, the holding load, and the escape load that the torsion spring 9 that is an elastic member bears. Since it is realized by the spring 10 which is a member, and the protrusions 11 and 12, the sliding operation can be easily performed in both the opening and closing directions, and a stable state can be maintained in the open state and the closed state. Further, the mobile phone 1 can be reduced in size by reducing the thickness, width, and height of the mobile phone 1 by using the slide operation component that can be reduced in size and the sliding operation component. Furthermore, since the sliding amount of the first housing 2 with respect to the second housing 5 of the mobile phone 1 is also limited by the size of the torsion spring, the sliding amount is increased by downsizing the torsion spring 9. Is also possible. Furthermore, by reducing the maximum load of the torsion spring 9, the load of the torsion spring 9 is reduced, and the reliability of the spring, that is, the reliability of the mobile phone 1 can be improved.

Embodiment 2. FIG.
In the first embodiment, in order to realize a holding force and an escape load, a spring 10 is provided as a locking member on the plane of the guide rail 7 that is in contact with the slide rail 6, and the locked member is mounted on the plane of the slide rail 6 that faces the sliding rail 6. Protrusions 11 and 12 are provided. In the second embodiment, the slide assist force generation mechanism is the same as that in the first embodiment, but the holding force and escape load mechanism is realized by a method different from that in the first embodiment. Specifically, the locked member attached to the slide module 8 is different from the mounting position of the locking member.

Further, in the first embodiment, since the locked portion is on the plane of the slide rail, the slide assisting force is weakened when it interferes with the housing 5 at the time of sliding, and may stop in the middle of the sliding operation. However, in the second embodiment, since the protrusions 14, 15, and 16 that are the locking portions are on the side surface of the slide rail 13, when the slide rail 13 slides, it slides smoothly without interfering with the housing 5.

The friction member 24 and the friction members 25 and 26 are configured by forming an elastic body such as a resin material or a cushion material as a part of the first casing 2 or the second casing 5, or fixed by claw fitting or adhesion. It is arranged by making it.

FIG. 25A is a front view of the mobile phone 1, and FIG. 25B is a left side view of the mobile phone 1. FIG. 25B shows a state where the friction member 24 and the friction member 25 are in contact with each other in the closed state. The first housing 2 functions as a latch by disposing the friction member 24 in contact with the friction member 25 in the closed state, and similarly, the friction member 24 contacts the friction member 26 in the open state. This arrangement functions as a latch. Further, a frictional force in the sliding direction is generated between the friction member 24 and the friction members 25 and 26 in the open state or the closed state, and this friction force realizes the holding force and the escape load in the open state or the closed state. , Can maintain a stable state.

  FIG. 26 is a graph showing the relationship between the slide load applied to the first casing 2 and the slide amount in the fifth embodiment. In FIG. 26, the horizontal axis represents the slide amount, and the vertical axis represents the slide load. When the slide amount is Xmin, the closed state is indicated. When Xmax is indicated, the open state is indicated. X1 indicates the direction of the slide load (sliding auxiliary force) is reversed. Indicates the position to perform.
