Through this protective panel 22, an LCD display, which will be described later, can be visually recognized. The protection panel 22 protects the LCD display while ensuring the visibility of the LCD display. Typically, protective panel 22 is formed from a synthetic resin composition. The central frame 20 and the protection panel 22 may be integrally formed. The protection panel 22 may be made of glass. The central frame 20 and the protective panel 22 constitute the display screen 4 of this operating device 2 .

A cantilever structure 24 is attached to the outer edge of the central frame 20 . A cantilever structure 24 projects outwardly from the central frame 20 . A plurality of cantilever structures 24 are attached to the central frame 20, as shown in FIGS. 2-4. In this embodiment six cantilevered structures 24 are attached to the central frame 20 .

As shown in FIG. 3, unevenness exists on the sides of the plate portion 28 in plan view. If the unevenness were not present, the plate portion 28 would have a rectangular shape or a rectangular shape with one end curved. Plate portion 28 includes a top surface 36 , a bottom surface 38 and a plurality of side surfaces 40 . The plate portion 28 of FIG. 5 has four side surfaces 40, a first side surface 40a, a second side surface 40b, a third side surface 40c and a fourth side surface 40d.

The second side surface 40b faces the first side surface 40a. As shown in FIG. 5, when viewed from the second side surface 40b side, the thickness of the plate portion 28 varies depending on locations. The thickness of the plate portion 28 is not constant. In this embodiment, when viewed from the side of the second side surface 40b, the thickness of the plate portion 28 is maximized at the position where it is connected to the support portion 30. As shown in FIG. This position is referred to as the maximum thickness position 42 . In this embodiment, the lower surface 38 of the plate portion 28 is inclined toward the upper surface 36 from the maximum thickness position 42 toward one end of the plate portion 28 (the end on the side of the third side surface 40c). This portion is referred to as a right slope portion 38a of the lower surface 38. As shown in FIG. As a result, the thickness of the plate portion 28 gradually decreases from the maximum thickness position 42 toward the end on the third side surface 40c side. In this embodiment, the lower surface 38 of the plate portion 28 is inclined toward the upper surface 36 from the maximum thickness position 42 toward the other end of the plate portion 28 (the end on the side of the fourth side surface 40d). This portion is referred to as the left slope portion 38b of the lower surface 38. As shown in FIG. Accordingly, the thickness of the plate portion 28 gradually decreases from the maximum thickness position 42 toward the end on the fourth side surface 40d side.

In the embodiment of FIG. 5, there is a portion of substantially constant thickness between the right slanted portion 38a and the left slanted portion 38b. This portion may not exist and the right slope portion 38a and the left slope portion 38b may be in contact with each other. At this time, at the maximum thickness position 42, the lower surface 38 presents a downwardly pointed shape.

The contact portion 32 is rod-shaped. The contact portion 32 protrudes from the lower surface 38 of the plate portion 28 . The contact portion 32 extends downward from the lower surface 38 of the plate portion 28 . As shown in FIG. 5 , in this embodiment, the contact portion 32 protrudes from the maximum thickness position 42 of the plate portion 28 . In this embodiment, the contact portion 32 is formed integrally with the plate portion 28 .

The mounting portion 34 protrudes from the lower surface 38 of the plate portion 28 . The mounting portion 34 extends downward from the end of the plate portion 28 on the second side surface 40b side. In this embodiment, two mounting portions 34 are connected to the plate portion 28 .

As shown in FIG. 6, when the pressing frame 8 is placed on the upper case 10, a gap 48 is provided between the plate portion 28 of the cantilever structure 24a and the upper case 10. As shown in FIG. Although not visible in FIG. 6, the upper case 10 is provided with a hole at a position corresponding to the contact portion 32 of the cantilever structure 24a. The contact portion 32 penetrates the upper case 10 by passing through this hole. Holes are also provided in the upper case 10 at positions corresponding to the mounting portions 34 . The gap 48 and the hole allow the plate portion 28 and the contact portion 32 to move downward when force is applied to the plate portion 28 from the upper surface 36 side and the support portion 30 is bent. In all the cantilever structures 24, when force is applied to the plate portion 28 from the upper surface 36 side and the support portion 30 is bent, the plate portion 28 and the contact portion 32 can move downward.

The plurality of keys 6 , the pressing frame 8 and the upper case 10 together form a lid portion 56 of the operating device 2 . These constitute a lid portion 56 with operation keys 6 .

The circuit board 12 is positioned below the upper case 10 as shown in FIG. The circuit board 12 comprises a substrate 50 and an LCD display 52 and a plurality of elements 54 mounted on the substrate 50 . These elements 54 constitute a circuit for realizing the functions of this operating device 2 . These elements 54 include switches. In this circuit board 12 , a plurality of switches are mounted on the board 50 . Each switch is located under the corresponding contact 32 . When the contact portion 32 contacts the corresponding switch, the state of the switch changes. For example, when the contact portion 32 contacts the switch, the switch is turned on. The switch is turned off by the contact portion 32 leaving the switch. When no force is applied to the plate portion 28, the contact portion 32 is not in contact with the switch.

The position of the LCD display 52 corresponds to the position of the opening 46 of the upper case 10 and the opening 26 of the central frame 20. As shown in FIG. Therefore, when the display screen 4 is viewed from above, the LCD display 52 can be visually recognized through the protection panel 22 and these openings.

A cushion 16 is positioned between the upper case 10 and the circuit board 12 . The cushion 16 prevents the LCD display 52 from applying strong force. Cushion 16 protects LCD display 52 .

The lower case 18 has a box shape with an open top. The circuit board 12 is placed inside the lower case 18 . A housing for housing the circuit board 12 is configured by covering the lower case 18 with the lid portion 56 with the operation keys 6 from above. The lower case 18 is made of hard material. Typically, the lower case 18 is made of a synthetic resin composition.

When operating the air conditioner, the user presses a desired key 6 of the operating device 2 . A force is applied to the plate portion 28 of the cantilever structure 24 positioned below the key 6 from the upper surface 36 side. The support portion 30 bends and the plate portion 28 moves downward. The contact portion 32 also moves downward and contacts the switch on the substrate 50 . The state of the switch changes and a corresponding signal is sent to the air conditioner. The air conditioner is thereby operated.

FIG. 7 is a front view showing a portion of the upper surface 44 of the upper case 10 and the cantilever structure 24 when the key 6 is pressed. When the key 6 is pressed, force is applied to the plate portion 28 from the upper surface 36 side, and the plate portion 28 and the contact portion 32 move downward. Thereby, the contact portion 32 is in contact with the switch.

In the state of FIG. 7, the user presses the right end of the key 6, so that force is applied to the right end of the plate portion 28 (the end on the third side surface 40c side). Therefore, the plate portion 28 moves downward, and the right end is lower than the left end. The plate portion 28 is inclined so that the right end is lowered. As shown in the figure, even if the plate portion 28 is tilted, the plate portion 28 is in contact with the upper case 10 because the bottom surface 38 of the plate portion 28 is tilted from the maximum thickness position 42 toward the end toward the top surface 36 side. not. In this operating device 2, even if force is applied to the edge of the plate portion 28, the plate portion 28 and the upper case 10 are prevented from coming into contact with each other before the contact portion 32 comes into contact with the switch and the state of the switch changes. , the inclination angle (thickness of the plate portion 28) of the lower surface 38 of the plate portion 28 is determined. The inclination of the plate portion 28 when force is applied to portions other than the ends of the plate portion 28 is smaller than the inclination when the force is applied to the ends of the plate portion 28 . In this case also, the plate portion 28 and the upper case 10 do not come into contact with each other before the contact portion 32 comes into contact with the switch and the state of the switch changes. In other words, in the operation device 2, regardless of which portion of the plate portion 28 on the upper surface 36 side is subjected to force, the plate portion 28 and the contact portion 32 contact the switch before the contact portion 32 contacts the switch and the state of the switch changes. The thickness of the plate portion 28 is determined so that it does not come into contact with the upper case 10. - 特許庁

The effects of the present invention will be described below.

In the cantilever structure 24 according to the present invention, when the plate portion 28 is viewed from the side of the second side surface 40b, the thickness of the plate portion 28 varies depending on locations. The lower surface 38 of the plate portion 28 is inclined toward the upper surface 36 from the maximum thickness position 42 toward the end. In the operation device 2 using the cantilever structure 24 as the internal structure of the key 6, even if the edge of the plate portion 28 is applied with force and the plate portion 28 tilts, the plate portion 28 is unlikely to come into contact with the upper case 10. . It is unlikely that the plate portion 28 will come into contact with the upper case 10 and the switch will not be operable. Therefore, compared to using a cantilever structure in which the thickness of the plate portion 28 is constant, the distance between the upper case 10 and the plate portion 28 (the distance between the upper case 10 and the plate portion 28 when no force is applied to the plate portion 28 is The minimum width of the gap 48 in the portion 28 can be reduced. This contributes to reducing the thickness of the operating device 2 . The operating device 2 is downsized.

The structure of this cantilever structure 24 is simple. This cantilever structure 24 does not require additional parts. The operating device 2 using this cantilever structure 24 achieves low cost.

In this embodiment, when the plate portion 28 is viewed from the side of the second side surface 40b, the plate portion 28 has the maximum thickness at the position where it is connected to the support portion 30. As shown in FIG. The support portion 30 is connected to a portion of the plate portion 28 where the thickness is the maximum. As a result, the area of the connecting portion between the support portion 30 and the plate portion 28 can be increased. This contributes to the strength of the cantilever structure 24 . This cantilever structure 24 has sufficient strength to withstand the load of force on the plate portion 28 . This operating device 2 is excellent in durability.

In this embodiment, the cantilever structure 24 is attached to the outer edge of the central frame 20 so as to project outward. In this manner, the cantilevered structure 24 can be attached anywhere around the circumference of the central frame 20 . This cantilever structure 24 can also be attached to the outside corners of the central frame 20 . This improves the degree of freedom in arranging the keys 6 and contributes to miniaturization of the operating device 2 . The operating device 2 is downsized.

In this embodiment, the cantilever structure 24 is attached to the central frame 20 so as to surround the entire perimeter of the central frame 20 . By doing so, many keys 6 can be arranged while suppressing an increase in the size of the operation device 2 . Even in the operating device 2 that requires many keys 6, miniaturization can be achieved.

In this embodiment, the contact portion 32 protrudes from the maximum thickness position 42 of the plate portion 28 . The plate portion 28 receives a reaction force from the contact portion 32 when the contact portion 32 contacts the switch. By doing so, the plate portion 28 has sufficient strength to withstand this reaction force. Furthermore, by doing so, the length of the contact portion 32 can be shortened. This contact portion 32 is hard to break. This operating device 2 is excellent in durability.

In this embodiment, regardless of the force applied to any portion of the upper surface 36 side of the plate portion 28, the plate portion 28 and the upper case 10 are separated before the contact portion 32 contacts the switch and the state of the switch changes. The thickness of the plate portion 28 is determined so that they do not come into contact with each other. By doing so, it is possible to prevent the plate portion 28 and the upper case 10 from coming into contact with each other so that the contact portion 32 cannot contact the switch. The device can be operated by pressing any part of the key 6 by the user. This operating device 2 is excellent in operability.

In the embodiments described above, the upper surface 44 of the upper case 10 was flat. When the upper surface of the upper case has unevenness, the thickness of the plate portion may be determined differently according to the unevenness. By doing so, it is possible to make the plate portion less likely to come into contact with the upper case, compared to using a cantilever structure having a plate portion with a constant thickness. The thickness of the operating device can be reduced compared to using a cantilever structure having a plate portion with a constant thickness. This operating device achieves miniaturization.

Although not shown, another operating device according to the invention comprises a pressing frame comprising a central frame and a cantilever structure, an upper case and a switch. In this cantilever structure, when viewed from the second side surface of the plate portion, the lower surface of the plate portion does not incline and the thickness of the plate portion is constant. This push frame is the same as the push frame 8 of FIGS. 3-5 except for this point. The upper case of this operating device, when viewed from the second side, has an upper surface that slopes downward leftward or rightward from a position corresponding to the position where the support portion of the plate portion is connected. is doing. When viewed from the second side, the gap between the plate portion and the upper surface of the upper case increases toward the end of the plate portion. This upper case is the same as the upper case 10 of FIG. 2 except for this point. The switches of this operating device are the same as the switches of the operating device 2 described above.

In this operating device, the upper surface of the upper case is inclined downward leftward or rightward from a position corresponding to the position where the supporting portion of the plate portion is connected. Therefore, even if force is applied to the edge of the plate portion and the plate portion is tilted, the plate portion is unlikely to come into contact with the upper case. As a result, the distance between the upper case and the plate portion can be reduced. This contributes to reducing the thickness of the operating device. This operating device achieves miniaturization.

In the above embodiments, the lower surface of the plate portion was flat. When the lower surface of the plate portion has unevenness, the shape of the upper case may be determined according to the unevenness. By doing so, it is possible to make it difficult for the plate portion to come into contact with the upper case. The thickness of the operating device can be reduced compared to using an upper case with a flat upper surface. This operating device achieves miniaturization.

Furthermore, the shape of the upper case is such that the plate and the upper case do not come into contact with each other before the contact portion comes into contact with the switch and the state of the switch changes even if force is applied to any part of the upper surface of the plate. may be determined. By doing so, it is possible to prevent the plate portion and the upper case from coming into contact with each other so that the contact portion cannot contact the switch. The user can operate the air conditioner by pressing any part of the key. This operating device is excellent in operability.
