Description

  The present invention relates to a power generation switch device in which a link mechanism is provided between a switch key and a power generation device.

  For example, a wireless switch is known as a switch for turning on / off an electronic device. Since the electronic switch and the switch can be arranged separately from each other in the wireless switch, the degree of freedom of the arrangement position of the electronic device and the switch is increased as compared with a device in which both are integrated. For this reason, it is convenient when there are restrictions on the arrangement positions of electronic devices and switches. In addition, a power generation switch device has also been proposed in which a power generation device is provided in a wireless switch in order to reduce battery use, thereby improving usability (see Patent Document 1).

  On the other hand, the number of switch keys to be operated (portions operated by fingers) tends to increase with the increase in the number of functions of electronic devices. In order to cope with this, it is conceivable to provide a link mechanism between the plurality of switch keys and the power generation device. This link mechanism is generally composed of a plurality of link members, and when these are engaged, the operation of the switch key is transmitted to the operated portion (power generation device).

The first link lever (70) is configured to engage with the switch key (11-16),
The second link lever (75) is configured to engage the first link lever (70);
This can be solved by a power generation switch device characterized in that a rotating body (73) is provided at an engagement position where the second link lever (75) of the first link lever (70) is engaged. .

  In addition, the said reference code is a reference to the last, and description of a claim is not limited by this.

  According to the disclosed power generation switch device, since the rotating body is provided at the engaging portion between the first link lever and the second link lever, the engagement between the first link lever and the second link lever is provided. The friction generated at the position can be reduced, and the operability of the switch key can be improved.

  The link mechanism 10 has a first link lever 70 and a second link lever 75. The link mechanism 10 is disposed between the switch keys 11 to 16 and the power generation device 30.

  The switch keys 11 to 16 are pressed by an operator. In the present embodiment, switch key 11 and switch key 14 (referred to collectively as switch key A), switch key 12 and switch key 15 (referred to collectively as switch key B), and switch key 13 The switch key 16 (referred to collectively as the switch key C) is integrated.

  Bearings 17 are formed on the three switch keys A to C. A shaft portion 82C is formed on the upper portion of the switch case 80 (configured by the base 81 and the upper cover 82). By mounting the bearing 17 on the shaft portion 82C, the switch keys A to C are attached to the switch case 80 in a swingable configuration.

  In addition, operation protrusions 11a to 16a extending downward (in the direction of Z2 in the drawing) are formed below the switch keys 11 to 16, respectively. Further, on the upper surface of the upper cover 82 constituting the switch case 80, an opening 82A corresponding to a position where the operation projections 11a to 16a are formed and a mounting hole 82B in which connecting members 83 to 87 described later are mounted are formed.

Further, the lower end portions (end portions on the arrow Z2 direction side in the figure) of the connecting members 83 to 87 are configured to face switches SW1 to SW5 described later.

  Therefore, when the switch keys 12-16 are pressed, the operated switch keys 12-16 press the pins of the corresponding connecting members 83-87. As a result, the pin moves down and switches the corresponding switches SW1 to SW5 from the OFF state to the ON state.

  Next, the link mechanism 10 will be described. The link mechanism 10 has a function of connecting the plurality of switch keys 12 to 16 and the power generation device 30.

  The link mechanism 10 has the first link lever 70 and the second link lever 75 as described above. The first and second link levers 70 and 75 are swingably disposed inside the switch case 80.

  The first link lever 70 includes a pair of link lever halves 70A and 70B. One link lever half 70A is configured to engage with any of the switch keys 11-13. And when either of the switch keys 11-13 is pressed, it is set as the structure rock | fluctuated in the direction shown by arrow A1 in a figure.

  The other link lever half 70B is configured to engage with any of the switch keys 14-16. When any of the switch keys 14 to 16 is pressed, it is configured to swing in the direction indicated by the arrow A2 in the figure.

  In addition, a roller 73 (rotary body) is provided on a longitudinal side edge 71 located on the arrow Y2 direction side of the link lever half body 70A in the drawing. The roller 73 is configured to be rotatably supported by a roller holder 74 formed integrally with the link lever half body 70A.

  The roller holder 74 is formed so as to protrude from the side edge portion 71 of the link lever half body 70A to the outside (the arrow Y2 direction side in the figure). Therefore, the roller 73 is also configured to protrude outward (Y2 direction) from the side edge 71 of the link lever half body 70A.

  The rotation center axis of the roller 73 is configured to be in the longitudinal direction of the link lever half body 70A (in the direction of arrows X1 and X2 in the drawing). Further, the arrangement position of the roller 73 is set to the center position (the center position in the directions of arrows X1 and X2 in the drawing) with respect to the longitudinal direction of the link lever half body 70A.

  Similarly, a roller 73 (rotary body) is also provided at the longitudinal side edge 71 located on the arrow Y1 direction side of the link lever half body 70B in the drawing. The roller 73 is configured to be rotatably supported by a roller holder 74 formed integrally with the link lever half body 70B.

  The roller holder 74 is formed so as to protrude outward (Y1 direction side in the figure) from the side edge 71 of the link lever half body 70B. Therefore, the roller 73 is also configured to protrude outward (Y1 direction) from the side edge 71 of the link lever half body 70B.

  The rotation center axis of the roller 73 is also configured to extend in the longitudinal direction of the link lever half body 70B (in the directions of arrows X1 and X2 in the drawing). In addition, the arrangement position of the roller 73 is set to the center position (the center position in the direction of arrows X1 and X2 in the drawing) with respect to the longitudinal direction of the link lever half body 70B.

  The link spring 76 is stretched between the link lever half body 70A and the link lever half body 70B. The link spring 76 has a function of returning the link lever half body 70A to its original position when the link lever half body 70A is swung in the A1 direction and when the link lever half body 70B is swung in the A2 direction. is there.

  The second link lever 75 is disposed between the first link lever 70 and the power generation device 30. The second link lever 75 is disposed at a position where the second link lever 75 engages with the link lever halves 70A and 70B when the link lever halves 70A and 70B swing. The second link lever 75 has a configuration in which an engagement protrusion 75A, an operation portion 75B, and a shaft portion 75C are integrally formed.

  The second link lever 75 is configured to be swingable in the direction indicated by the arrow A3 in the figure by bearing the shaft part 75C located at the end on the arrow X1 direction side in the figure on the switch case 80. Yes. The operation portion 75B is located at the end opposite to the shaft portion 75C, and is configured to engage with an operation lever 32 provided in the power generation device 30 described later.

  The engagement protrusion 75A is formed between the operation portion 75B and the shaft portion 75C. The engagement protrusion 75A is a protrusion having a semicircular cross section formed so as to protrude upward (in the direction of arrow Z1) and to extend in the width direction (in the direction of arrows Y1, Y2).

  The engagement protrusion 75A is provided at a position where the link lever halves 70A and 70B and the second link lever 75 are engaged. The roller 73 is also provided at a position where the link lever halves 70A and 70B and the second link lever 75 are engaged. Therefore, in the power generation switch device 1 according to the present embodiment, when the link lever halves 70A and 70B and the second link lever 75 are engaged, the roller 73 and the engagement protrusion 75A are engaged.

  Therefore, when any of the switch keys 11 to 13 is pressed and the link lever half body 70A swings in the direction of the arrow A1, the roller 73 provided on the link lever half body 70A causes the engagement protrusion of the second link lever 75 to be engaged. Engage with 75A and press it. As a result, the second link lever 75 swings in the arrow A3 direction.

  In addition, when any one of the switch keys 14 to 16 is pressed and the link lever half body 70B swings in the direction of the arrow A2, the roller 73 provided on the link lever half body 70B causes the second link lever 75 to move. Engage with the engaging protrusion 75A and press it. Therefore, also in this case, the second link lever 75 swings in the arrow A3 direction.

  An operation portion 75B formed at the distal end portion of the second link lever 75 is configured to engage with the operation lever 32 of the power generation device 30. Therefore, when the second link lever 75 swings, the operation lever 32 is pressed and swings in the arrow A4 direction. In this way, when the operation lever 32 is operated, the power generation device 30 generates power.

  The power generation device 30 is provided with an operation lever 32, a circuit board 40 (shown as a circuit diagram in FIG. 4), a generator (not shown), and the like in a rectangular casing 31. In this embodiment, a motor is used as the generator. The operation lever 32 and the generator are connected to each other. Therefore, when the operation lever 32 is operated, the generator rotates to generate power (generate induced electromotive force).

  The circuit board 40 is attached to the opening portion of the housing 31. The circuit board 40 is provided with a switch control circuit 41, a transmission circuit 42, an antenna 43, and the like shown in FIG. Electric power generated by the generator is supplied to the circuits 41 and 42 formed on the circuit board 40, and the circuits 41 and 42 are driven by the electric power.

  The switch control circuit 41 is connected to the switches SW1 to SW5. The switch control circuit 41 corresponds to the switch operation of the plurality of switches SW1 to SW5 and outputs a plurality of different switch signals corresponding to the switches SW1 to SW5.

  The transmission circuit 42 transmits a switch signal toward the electronic device. When a switch signal is transmitted from the switch control circuit 41, the transmission circuit 42 transmits a switch signal having a frequency corresponding to the switch signal from the antenna 43 to the electronic device. As a result, the electronic device can perform an operation corresponding to the transmitted switch signal.

  The switch board 60 is a circuit board on which switches SW1 to SW5 are arranged on the upper surface. The switch SW1 is disposed so as to face the connecting member 83. Similarly, the switch SW2 faces the connecting member 84, the switch SW3 faces the connecting member 85, the switch SW4 faces the connecting member 86, and the switch SW5 faces the connecting member 87. It is configured. And when switch pin 12-16 is operated and the pin of connecting member 83-87 moves down, corresponding switch SW1-SW5 switches from an OFF state to an ON state.

  Next, the operation of the power generation switching device 1 having the above configuration will be described.

  1 and 2 show a state where the switch keys 11 to 16 are not operated. In this pre-operation state, the first link lever 70 (link lever halves 70A and 70B) and the second link lever 75 are substantially horizontal without swinging. Further, in this pre-operation state, as shown in an enlarged view in FIG. 6, the roller 73 and the engaging protrusion 75A are in a separated state.

  On the other hand, FIG. 5 shows a state where the switch key 15 is operated. A connecting member 86 and a switch SW4 are disposed below the switch key 15. Therefore, when the switch key 15 is pressed, the pin of the connecting member 86 is pressed, and the switch SW4 is switched from the OFF state to the ON state.

  At the same time, when the switch key 15 is pressed, the operation protrusion 15a engages with the link lever half body 70B and presses it downward. As a result, the link lever half body 70B swings as shown by an arrow A2 in FIG. 5, and the roller 73 provided on the link lever half body 70B is engaged with the engagement protrusion 75A formed on the second link lever 75. Engage with. 7 and 8A show a state in which the roller 73 is engaged with the engagement protrusion 75A.

  When the switch key 11 is further pressed from this state, the link lever half body 70B further swings in the A2 direction. As the link lever half body 70B swings, the roller 73 rolls on the engagement protrusion 75A in the inner direction (in the direction of arrow Y2 in the figure) while moving the engagement protrusion 75A downward (in the direction of arrow Z2 in the figure). Press on. Accordingly, the second link lever 75 swings in the arrow A3 direction, and the operation unit 75B swings the operation lever 32 in the arrow A4 direction. Therefore, when the switch key 15 is operated, the link mechanism 10 performs the above operation, and the power generation apparatus 30 generates power.

  As described above, the power generation device 30 and the switches SW1 to SW5 are connected to the switch control circuit 41 (see FIG. 4). Therefore, the switch control circuit 41 detects that the switch key 15 is operated because the power generation device 30 is generating power and the switch SW4 is in the ON state and the other SW1 to SW3 and SW5 are in the OFF state. can do.

  Here, attention is paid to the operation after the roller 73 is engaged with the engagement protrusion 75A.

  As described above, the engagement protrusion 75A is a protrusion whose cross section protrudes upward in a semicircular shape, and is formed so as to extend in the width direction (arrow Y1, Y2 direction). On the other hand, the roller 73 has a cylindrical shape, and the rotation center axis thereof is configured to be in the directions of arrows X1 and X2 in the drawing.

  That is, the rotation axis direction (X1, X2 direction) of the roller 73 and the extending direction (Y1, Y2 direction) of the engagement protrusion 75A are orthogonal to each other. Accordingly, the roller 73 and the engaging protrusion 75A come into point contact at the engaging position between the roller 73 and the engaging protrusion 75A. Further, the roller 73 is configured to be rotatable with respect to the roller holder 74. Therefore, the frictional force generated when the roller 73 moves on the engagement protrusion 75A is extremely small.

  As described above, the frictional force generated at the engagement position between the roller 73 and the engagement protrusion 75A is reduced, so that the operation force when the switch key 15 is pressed can be reduced. The operability can be improved.

  In the above description of the operation, the operation when the switch key 15 is operated is described as an example. However, the first link lever 70 swings when any of the switch keys 11 to 16 is operated. The roller 73 engages with an engagement protrusion 75 </ b> A formed on the second link lever 75. Therefore, when any of the switch keys 11 to 16 is operated, the same operation and action as when the switch key 15 is operated are generated, and the operability of the power generation switch device 1 can be improved.

  Next, a modified example of the power generation switch device 1 according to the above-described embodiment will be described. FIG. 8B shows an enlarged view of the first link lever 70 and the second link lever 75 of the power generation switch device according to this modification.

  In the embodiment described above, the roller holder 74 is formed on the side edge 71 of the link lever halves 70A and 70B so as to protrude outward (Y1 direction or Y2 direction). The projecting configuration was as follows.

  On the other hand, in this modified example, the roller 73 is placed below the facing surface 72 of the first link lever 70 (link lever half bodies 70A and 70B) facing the second link lever 75 (in the direction of arrow Z2 in the figure). ) Is provided so as to protrude.

  By providing the roller 73 so as to protrude downward on the facing surface 72 of the first link lever 70 as in the present modification, the width dimension (the length in the short direction, ie, the arrow Y1) of the first link lever 70. , Length in the Y2 direction) can be shortened. Therefore, in the installation space of the power generation switching device 1, this modification is effective particularly when there is a restriction in the width direction.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments described above, and various modifications are possible within the scope of the gist of the present invention described in the claims. It can be modified and changed.
