Description

  The present invention relates to an electrical equipment switch device. More specifically, the present invention relates to an electrical equipment switch device including a set of a plurality of switch elements in which a tact switch tact is pushed down through a push button pressing operation.

  FIG. 7 is a partially longitudinal side view showing individual switch elements employed in this type of conventional electrical equipment switch device. The switch element includes a tact switch 10 and an operation member 20. The tact switch 10 is mounted on a wiring board (not shown) in an upright posture in which the tact 12 protrudes upward. When the tact 12 is pushed down from the initial position, the mode is switched from off to on or from on to off. Is called. On the other hand, the operation member 20 is a plate-like operation piece 21 extending from the position of the fulcrum P formed by an elastic resin hinge, and the operation member 20 extends perpendicularly from the back surface of the operation piece 21. The projecting piece 22 and the push button 23 are formed, and the lower surface of the tip end portion of the projecting piece 22 is formed as an action portion 24 facing the tact 12 of the tact switch 10 from above, and the push button 23 is It is formed integrally with the operated piece 21 and protrudes forward from the front surface of the operated piece 21. Further, in addition to the mounting portion 25 integrally formed on the opposite side of the operated piece 21 across the position of the fulcrum P being fixed to the front panel 100 of the electric equipment cabinet, the push button 23 is provided on the front side thereof. The operation piece 21 is disposed so as to be able to be pushed into the hole 110 formed in the panel 100, and the operated piece 21 is always directed toward an initial position standing along the inner surface of the front panel 100 by the elastic restoring force applied to the fulcrum P. The bullet is energized.

  In this switch element, when the operator (user) pushes the push button 23 with the finger of the hand as shown by an arrow F as shown in FIG. 7B, the operated piece 21 and the action piece 22 are moved to the initial positions (FIG. 7A). ), The tact 12 is pushed down by the action part 24 of the projecting piece 22 and the mode of the tact switch 10 is switched. In addition, the code | symbol T1 of FIG. 7 has shown the pressing amount of the tact 12 when the tact 12 is pressed down and the mode of the tact switch 10 switches.

  In this switch element, the pushing stroke Sx of the push button 23 in the pushing process, specifically, the mode switching of the tact switch 10 by the action unit 24 depressing the tact 12 of the tact switch 10 from the time when the push button 23 starts to be pushed. The pushing stroke Sx of the push button 23 in the pushing process up to the point in time is the distance B between the center position of the push button 23 (hereinafter referred to as “push button position”) and the position of the fulcrum P (hereinafter referred to as “fulcrum position”). It is determined by the relationship between the fulcrum position and the separation distance A of the center position of the tact 12 (hereinafter referred to as “tact position”), and if the value of B / A, which is the ratio of both, increases, the pushing stroke Sx increases, and B / A If the value of becomes smaller, the pushing stroke Sx becomes smaller.

  In addition, the click feeling that the operator can perceive sensibly with the finger of the hand through the push button 23 by performing the above-described pushing process is a slight impact feeling that the tact switch 10 exhibits when the mode of the tact switch 10 is switched. If it is formed by the behavior of the operating member 20 (for example, the swing speed distribution) performed throughout the pushing process including the feeling of impact, the click feeling is not obtained. The button 23 is greatly influenced by the pressing stroke Sx.

  Therefore, the quality of use when the operator uses the switch element is affected by the pressing stroke Sx and the click feeling in the pressing process. In other words, in order to improve the feeling of use of the switch element, the switch element has a click feeling that depends on the push stroke Sx in the push process or the behavior of the operation member 20 due to its structure. It can be beneficial to be able to control appropriately.

  A large number of switch elements having the structure described with reference to FIG. 7 are provided in various electric devices such as a DVD drive and a television receiver. This case will be further described with reference to FIG.

  FIG. 6 is an explanatory diagram showing an example of the arrangement of a plurality of switch elements in an electric device composed of a DVD drive. In the electrical apparatus of FIG. 1, tact switches 10 are arranged side by side at a plurality of positions at the same height level, and one push button 23 assigned to each tact switch 10. Are respectively provided in different hole portions 110. The plurality of switch elements include those having different vertical distances D1 and D2 from the push button 23 to the tact switch 10 due to restrictions on the appearance design of the front panel 100 and convenience. Between the switch elements having different D1 and D2, the separation distance B between the push button position and the fulcrum position shown in FIG. 7A is inevitably different.

  Therefore, if the switch element having a short separation distance B between the push button position and the fulcrum position is the first switch element and the switch element having the long separation distance is the second switch element, the push button pushing stroke Sx ( In FIG. 7B, the second switch element is longer than the first switch element, and the click feeling is different between the first switch element and the second switch element.

  On the other hand, when the tact knob for operating the tact switch (corresponding to the above push button) is provided with an inclined contact surface for the switch element described with reference to FIG. Is known to act on the tact of a tact switch (see, for example, Patent Document 1). According to this technique, the inclination angle of a flat contact surface is changed, or the contact surface is changed to an arc surface. It is said that the pushing stroke of the tact knob for operating the tact switch changes.

  In addition, regarding the knob structure of the switch panel in which operation knobs with different fulcrum and action point distances are mixed, a reaction force increasing means is provided on the operation knob with a longer distance than the operation knob with the shortest distance between the fulcrum and action points Thus, a technique for making the operating forces of both the same is known (for example, see Patent Document 2).

Furthermore, regarding the push button pressing structure, if the position of the pivot center of the pressing piece for pressing down the tact switch tact switch is changed in the perspective direction with respect to the push button, the pressing stroke of the push button can be increased or decreased. It has been suggested (see, for example, Patent Document 3).
Japanese Utility Model Publication No. 6-13031 JP-A-10-64357 Utility Model Registration No. 3094915

  By the way, in a plurality of switch elements equipped in the same electrical device, the push stroke Sx of the push button 23 in the push process is different as in the relation between the first switch element and the second switch element described above. In this case, it is known for the operator that the feeling of clicking when the push button 23 is pushed in between the first and second switch elements is different and the feeling of use is impaired. In order to improve this feeling of use, the click feeling of both is approximated by taking a measure that can approximate the pushing stroke Sx of the push button 23 in the pushing process of the first switch element and the second switch element. It is beneficial.

  In this regard, the one proposed in Patent Document 1 changes the inclination angle of the flat contact surface on the tact knob side, which is susceptible to size restrictions, or curves the contact surface in an arcuate shape. Since it is only a mechanism that adjusts the indentation stroke, the adjustment range of the indentation stroke is narrow, and the tact switch of the lying posture is pushed down directly by the contact surface, so the tact behavior in the indentation process It is clear that the degree of freedom in changing the angle is poor, and it can be said that it is difficult to adjust the tact knob push-in stroke and the click feeling in the push-in process in a wide range.

  In addition, what is proposed by Patent Document 2 requires an extra reaction force increasing means, which increases the number of parts, which increases the assembly cost due to an increase in parts cost and assembly man-hours. There is a problem of being connected. Furthermore, since what is proposed by Patent Document 3 changes the position of the swing center of the pressing piece, the operator pushes the push button with the change of the position of the swing center of the pressing piece. As the force also changes, it is difficult to uniformly determine the click feeling.

  In addition, all of those proposed in Patent Documents 1, 2, and 3 are such that the push-in operation of the push button is performed by a swinging motion around a fulcrum at a predetermined position. It can be said that it is unavoidable that a sense of incompatibility occurs due to the pressing.

  Therefore, the present invention provides a tactile switch 10 from a push button 23 as described with reference to FIG. 6 in a switch device having a plurality of switch elements having the configuration of the conventional example described with reference to FIG. When the first and second switch elements having different vertical distances D1 and D2 are included, the pushing stroke of the push button 23 in the pushing process for both the switch elements is approximated, and both switches An object of the present invention is to provide an electric device switching device that can improve the feeling of use by an operator by approximating the click feeling of an element.

  The electrical equipment switch device according to the present invention includes a tact switch and an operation member that is swingable about a fixed position fulcrum and is always elastically biased toward an initial position by an elastic restoring force applied to the fulcrum. The operation members of the individual switch elements are operated pieces extending from the fulcrum position, and the operated pieces are retracted from the initial position around the fulcrum through the pushing operation. And a push button that is provided on the operation piece and that pushes down the tact switch of the tact switch through a swinging operation of the operation piece in the backward direction. First and second switch elements having different separation distances between the position and the fulcrum position are included.

  In each of the first and second switch elements, the push button is separated from the operation member so that the push button can be pushed on a straight path, and the push button side is operated with respect to the operated piece. At least one surface of the pressing portion and the receiving portion on the operated piece side on which the pressing portion slides during the pressing operation of the push button is formed as a cam surface, and from the start of pressing the push button of each switch element The pushing stroke of the push button in the pushing process up to the point of time when the tact switch is switched by the action part depressing the tact switch is controlled according to the shape of the cam surface. Pushing of the push button in the pushing process of the respective switch elements by making the shapes of the cam surfaces of the first and second switch elements different It is set to the same a stroke. In this invention, when a curved surface is adopted as the cam surface, curved surfaces with different curvatures fall within the category of cam surfaces with different shapes, and when a flat surface is adopted as the cam surface, the push button is depressed. It is assumed that flat surfaces having different inclination angles with respect to directions fall into the category of cam surfaces having different shapes.

  With the above configuration, since the push button is pushed on the straight path in the pushing process, the operator does not feel uncomfortable and the feeling of use related to the pushing operation of the push button is improved.

  In the present invention, in particular, by adopting a configuration in which at least one surface of the pressing portion on the push button side and the receiving portion on the operated piece side is a cam surface and the shape of the cam surface is different, the pressing step The pushing strokes of the pushbuttons of the first and second switch elements are set to be the same. For this reason, for example, it is possible to determine the shape of the cam surface so that the behavior of the operated piece of the first switch element in the pushing process is directly reflected in the behavior of the operated piece of the second switch element. Thus, the behavior of the operated piece of the second switch element can be made the same as the behavior of the operated piece of the first switch element. Therefore, according to the present invention, not only can the pressing strokes of the pushbuttons of the first and second switch elements be set to the same, but also the click feeling affected by the behavior of the operated piece is set to the same. It is possible to improve the feeling of use by the operator.

  Further, in the present invention, the tact switch is not directly pressed down by the pressing portion on the push button side, but an operation member with less size restrictions is interposed between the push button and the tact switch, and the operation is performed. Since the structure in which the pressing portion is slid on the receiving portion on the operated piece side of the member is employed, the degree of freedom in changing the shape of the cam surface is increased and depends on the behavior of the operated piece performed throughout the pushing process. The click feeling can be adjusted in a wide range, which helps to easily adjust the feeling of use.

  In the present invention, on the first switch element side, the cam surface is formed flat on the surface of the receiving portion of the operated piece, whereas in the second switch element, the pressing portion and the receiving portion It is possible to adopt a configuration in which at least one surface is formed as a cam surface having a shape that can match the pushing stroke of the push button in the pushing process of the second switch element with that of the first switch element. It is. In this case, it is possible to employ a configuration in which the separation distance of the second switch element is set longer than the separation distance of the first switch element. If it is this structure, the shape of the cam surface of a 1st switch element will be simplified, and it will become possible to manufacture a 1st switch element so that it is cheap.

  The electrical equipment switch device according to the present invention includes a tact switch and an operation member that is swingable about a fixed position fulcrum and is always elastically biased toward an initial position by an elastic restoring force applied to the fulcrum. The operation members of the individual switch elements are operated pieces extending from the fulcrum position, and the operated pieces are retracted from the initial position around the fulcrum through the pushing operation. And a push button that is provided on the operation piece and that pushes down the tact switch of the tact switch through a swinging operation of the operation piece in the backward direction. The first and second switch elements having different separation distances between the position and the fulcrum position are included, and the separation distance of the second switch element is greater than the separation distance of the first switch element. In the electrical device switch device which is long, the action portion is formed by a tip portion of a protruding piece extending perpendicularly from the back surface of the operated piece, and in each of the first and second switch elements The push button is separated from the operation member so that the push button can be pushed on a straight path, and the push portion with respect to the operated piece on the push button side and the push portion when the push button is pushed A tact switch in which at least one surface with the receiving part on the operated one side that slides is formed as a cam surface, and the action part pushes down the tact switch of the tact switch from the start of pressing the push button of each switch element The pushing stroke of the push button in the pushing process up to the time of mode switching is controlled according to the shape of the cam surface. In both cases, the shape of the cam surface of each of the first and second switch elements is made different so that the pushing stroke of the push button in the pushing process of each of the switch elements is set to be the same. On the first switch element side, The cam surface is formed flat on the surface of the receiving portion of the actuated piece, whereas in the second switch element, at least one surface of the pressing portion and the receiving portion is the second switch element. The present invention is further embodied by adopting a configuration in which the pushing stroke of the push button in the pushing step is formed as a cam surface having a shape that can match that of the first switch element. The configuration and operation of the present invention will be described in detail with reference to embodiments described later.

  As described above, according to the present invention, in the electrical equipment switch device including the first and second switch elements having different distances from the push button to the tact switch, both of the switch elements are pushed in the pushing process. It is possible to provide an electric device switch device that can approximate the push-in stroke of the push button without increasing the number of parts and can also approximate the click feeling of both switch elements. Therefore, for the operator, there is an advantage that the feeling of use of the plurality of switch elements is uniform and the usability of the electric device is improved.

  FIG. 1 is a partially longitudinal side view of a configuration example of a first switch element A1 included in a switch device according to the present invention, and FIG. 2 is a partially longitudinal side view of a configuration example of a second switch element A2 included in the switch device. .

  The configuration of each switch element A1, A2 in FIG. 1 and FIG. 2 is as follows. That is, each switch element A 1, A 2 includes a tact switch 10 and an operation member 20. The tact switch 10 is mounted on a wiring board (not shown) in an upright posture in which the tact 12 protrudes upward, and mode switching is performed when the tact 12 is pushed down from the initial position. The operation member 20 includes a plate-like operation piece 21 extending upward from the position of the fulcrum P formed by a resin hinge having elasticity, and a protrusion extending perpendicularly from the back surface of the operation piece 21. It has a piece 22 and a push button 23, and the bottom surface of the tip of the protruding piece 22 is formed as an action part 24 that faces the tact 12 of the tact switch 10 from above. Further, in addition to the attachment portion 25 integrally formed on the opposite side of the operated piece 21 across the position of the fulcrum P, the attachment portion 25 is fixed to the front panel 100 of the electric equipment cabinet (the fixing portion is not shown), A push button 23 is provided in the hole 110 formed in the front panel 100. Further, the operated piece 21 is constantly elastically biased toward an initial position where it rises along the inner surface of the front panel 100 by an elastic restoring force applied to the fulcrum P. Further, the push button 23 is configured as a separate body separated from the operated piece 21, and this push button 23 can be pushed down on a straight path by being guided by the hole 110 or other guide. It has become.

  In the first and second switch elements A1 and A2, when the operator pushes the push button 23 with the finger of the hand as indicated by the arrow F, the operated piece 21 and the action piece 22 are changed from the initial position as indicated by the arrow a. As the rocker swings and tilts in the backward direction, the tact 12 is pushed down by the action portion 24 of the protruding piece 22 and the mode of the tact switch 10 is switched. When the operator pushes the push button 23 with the finger of the hand, the push button 23 recedes straight as indicated by the arrow L, so that the operator does not feel uncomfortable and the push button 23 is depressed. Usability is improved.

  Furthermore, in each of the first and second switch elements A1 and A2, the back surface of the push button 23, in other words, the surface of the pressing portion 30 (the pressing portion surface) with respect to the operated piece 21 on the push button 23 side is a cam. Whereas the surface is formed as a surface, the surface of the pressing portion 30 slides on the surface of the receiving portion 40 on the operated piece 21 side when the push button 23 is pressed. In the pushing process of the push button 23, specifically, in the pushing process from the time when the push button 23 starts to be pushed to the time when the tact switch 10 is switched to the mode when the action unit 24 pushes down the tact 12 of the tact switch 10. The push stroke of the push button 23 is controlled according to the shape of the cam surface formed by the surface of the push portion 30, and the action portion 24 of the push button 23, the operated piece 21, and the protruding piece 22. The behavior of the operation member 20 including the above is controlled in accordance with the shape of the cam surface.

  In each of the first and second switch elements A1 and A2 specifically shown in FIGS. 1 and 2, the cam surface formed on the pressing portion surface is drawn in an arc shape in a side view. The shape of the cam surface is not limited to this, and is merely illustrative and schematic. Moreover, although the surface of the receiving part 40 shown in FIG.1 and FIG.2 is drawn flat, this also only represents the surface shape of the receiving part 40 only explanatoryly and typically, The surface shape of 40 is not limited to this. For example, it may be formed as a cam surface having an arc shape or other shapes. That is, in each of the first and second switch devices A1 and A2, at least one surface of the pressing portion 30 on the push button 23 side and the receiving portion 40 on the operated piece 21 side is formed as a cam surface. That's fine. Specifically, even if only the surface of the pressing portion 30 is used as a cam surface and the receiving portion 40 is formed as a counterpart sliding protrusion that follows the cam surface, conversely, only the surface of the receiving portion 40 is pressed as a cam surface. Even if the portion 30 is formed as a counterpart sliding protrusion that follows the cam surface, the cam surfaces of the pressing portion 30 and the receiving portion 40 are used as the cam surfaces, and the cam surfaces of both of them slide relative to each other. You may also.

  As described above, in each of the first and second switch elements A1 and A2, at least one surface of the pressing portion 30 on the push button 23 side and the receiving portion 40 on the operated piece 21 side is formed as a cam surface. In other words, in each of the switch elements A1 and A2, the pushing stroke of the push button 23 in the pushing process changes according to the shape of the cam surface, and the behavior of the operated piece 21 is also controlled according to the shape of the cam surface. The Therefore, by appropriately determining the shape of the cam surface for each of the switch elements A1 and A2, it is possible to approximate the push stroke of the push button 23 in the push process, and in addition, in the push process. It is possible to approximate the behavior of the operated piece 21 and the like.

  This point will be specifically described with reference to FIGS. FIG. 3 is an explanatory view of an example in which the receiving portion 40 is a curved cam surface and the pressing portion 30 is an opposing sliding protrusion, and FIG. 4 is an exemplary embodiment where the receiving portion 40 is a flat cam surface and the pressing portion 30 is an opposing sliding protrusion. It is explanatory drawing of a case. 3 and 4, the protruding piece 22 and the tact switch 10 shown in FIGS. 1 and 2 are not shown.

  In the case of FIG. 3, the surface of the receiving part 40 forming the cam surface is aligned along the sliding direction of the pressing part 30 with respect to the receiving part 40 (direction indicated by arrow m in the drawing) in the pressing process. It consists of a set of multiple sections with different shapes. Specifically, a flat first section 41 inclined forward with respect to the sliding direction m, a flat second section 42 substantially parallel to the sliding direction m, and a sliding direction m On the other hand, the cam surface is formed by a set with the third section 43 inclined forward and protruding forward. When the receiving portion 40 is provided with the cam surface having such a shape, when the operated piece 21 swings in the backward direction as shown by the arrow a around the fulcrum P in the pushing process, the operated piece 21 The rocking speed of 21 changes according to the contact position of the pressing part 30 with respect to the cam surface. That is, the operated piece 21 swings at a speed corresponding to the inclination of the first section 41 of the cam surface in the first stage swing from the initial position indicated by the solid line to the position indicated by the broken line a. In the second-stage swing from the position indicated by dash-dot line b to the position indicated by dash-dot line b, the cam surface is swung at a speed corresponding to the inclination of the second section 42 of the cam surface, and from the position indicated by dash-dot line b In the third-stage swing to the position indicated by c, the swing is performed at a speed corresponding to the inclination of the third section 43 of the cam surface. When the operated piece 21 swings to the position indicated by the two-dot chain line C, the pushing process is completed, and the tact 12 of the tact switch 10 shown in FIG. 2 is pushed down to switch the mode. Then, the pushing stroke of the push button 23 in the pushing step becomes the length indicated by the symbol Sx1 in the same drawing. In the figure, the pushing strokes of the push button 23 at the first to third stages are indicated by reference numerals S1, S2, and S3.

  In contrast to the case of FIG. 3, in the case of FIG. 4, the receiving portion 40 is formed as a flat cam surface and the pressing portion 30 is formed as a counterpart sliding protrusion. The swing angle from the initial position of the operated piece 21 until the tact 12 of the switch 10 is pushed down and the mode is changed is larger than that in the case of FIG. Therefore, in the case of FIG. 4, the push stroke of the push button 23 at the stage when the push process is completed has the length indicated by the symbol Sx2 in the figure, and this push stroke Sx2 is the push stroke in the case of FIG. It becomes larger than Sx1 (Sx1 <Sx2).

  By comparing the case of FIG. 3 and the case of FIG. 4 described above, it can be seen that the push stroke of the push button 23 in the push step changes by changing the shape of the cam surface. Similarly, it can also be seen that the swing speed of the operated piece 21 throughout the pushing process also changes sequentially in accordance with the shape of the cam surface. Accordingly, in the first switch element A1 shown in FIG. 1 and the second switch element shown in FIG. 2, the shapes of the cam surfaces provided in both are made different and the shapes of the respective cam surfaces are appropriately determined. Accordingly, the push stroke of the push button 23 in the push process in each of the switch elements A1 and A2 having different distances (distances corresponding to D1 and D2 shown in FIG. 6) from the push button 23 to the tact switch 10 is approximated. It is possible to approximate the behavior of the operated piece 21 in the pushing process.

  And in order to approximate the pushing stroke in each switch element A1, A2 from which the distance from the push button 23 to the tact switch 10 and the operation piece 21 in the pushing process are approximated, for example, the following method is used. It is beneficial to adopt. That is, on the basis of the pushing stroke of the first switch element A1 and the behavior of the operated piece 21 in the pushing process, the pushing stroke of the push button 23 at a plurality of times during the pushing process is measured for the first switch element A1. Data is created by associating the value with the measured value of the amount of depression of the tact switch 10 of the tact switch 10 (see FIG. 1) by the action part 24 of the operated piece 21 at each time point. The shape of the cam surface of the second switch element A2 is determined so that the same value as the actually measured value of the pushing stroke for one switch element and the measured value of the pressing amount of the tact 12 can be obtained for the second switch element A2. Is beneficial.

  Therefore, for example, on the first switch element A1 side shown in FIG. 1, the cam surface is formed flat on the surface of the receiving portion 40, whereas in the second switch element A2 shown in FIG. By determining the shape of the cam surface on at least one surface of the receiving portion 40 by the above method, the pressing stroke and the click feeling of the push button 23 of the second switch element A2 can be easily matched to those of the first switch element A1. It becomes possible.

  In the example of FIG. 3, the receiving portion 40 is a curved cam surface and the pressing portion 30 is a counterpart sliding protrusion. However, this point is that both the pressing portion 30 and the receiving portion 40 are smooth as shown in FIG. 5. It is also possible to use a cam surface having a continuous curved surface. In addition, in the case where only one of the pressing portion 30 and the receiving portion 40 is provided with a cam surface as shown in FIGS. 3 and 4, which of the pressing portion 30 and the receiving portion 40 is formed with the cam surface. Whether the cam surface is formed by the above-described assembly or a single unit, whether the cam surface is formed in an angular shape or a smoothly continuous curved surface, and the like are desired. This should be selected as appropriate in consideration of the feeling of use. About these points, it is the same also when providing both the press part 30 and the receiving part 40 with a cam surface like FIG.

  In the first switch element A1 in FIG. 1 and the second switch element A2 in FIG. 2, an operated piece 21 having an action portion 24 is interposed between the push button 23 separated from the operation member 20 and the tact switch 10. The restriction on the size of the operated part 21 is less than the restriction on the size of the push button 23. Therefore, the size of the cam surface that can be formed by the surface of the receiving portion 40 of the operated piece can be easily increased, but there is an advantage that the degree of freedom in selecting the shape of the cam surface increases accordingly. As a result, not only the adjustment range of the pressing strokes Sx1 and Sx2 (see FIG. 3 or 4) of the push button 23 in the pressing process is expanded, but also the adjustment range of the click feeling affected by the behavior of the operation member 20 is expanded.
