Description

Operating device

Technical Field

The present invention relates to an operating device.

Background

There is provided an operation device for remotely operating a device such as an air conditioner provided in a building, the operation device being mounted to a wall. As such an operation device, there is an operation device provided with: a display module that displays the temperature, humidity, and the like of a room in which the air conditioner is installed; a control board on which various electronic components are mounted and which transmits control information for controlling the air conditioner to the air conditioner; and a frame body which houses the display module and the control substrate.

Problems to be solved by the invention

However, in the display device described in patent document 1, since the frame-shaped upper case is formed of a resin material, the thickness and width thereof have to be increased in order to increase the strength of the upper case. Therefore, the outer size of the upper case becomes large, and the outer size of the entire display device also becomes large. In addition, in the case of an operation device having the same configuration as that of such a display device, the external dimensions thereof become large, and therefore, there is a possibility that the space in which the operation device can be installed is limited. In addition, in the case of the wall-mounted operating device, if the external dimensions thereof become large, the possibility that a person in a room in which the operating device is installed may erroneously touch the operating device and damage the operating device is also increased. Further, if the external dimensions of the operation devices are increased, it is difficult to collectively provide a plurality of operation devices in a limited area of the wall, which may impair the external appearance.

The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a manipulation device which is improved in strength and reduced in size.

Means for solving the problems

In order to achieve the above object, an operation device of the present invention includes: a user interface device; a control substrate on which electronic components are mounted and which controls the user interface device and external equipment; and a housing that houses the user interface device and the control board. The frame body has: a frame body formed of a non-conductive resin; and a reinforcing member formed of a metal having a higher elastic modulus than the resin, fixed to the housing body in a state in which at least a part thereof is exposed to the outside of the housing, and reinforcing the housing body.

Effects of the invention

According to the present invention, the frame body includes the frame body formed of a nonconductive resin, and the reinforcing member formed of a metal having a higher elastic modulus than the resin, and is fixed to the frame body in a state in which at least a part thereof is exposed to the outside of the frame body, thereby reinforcing the frame body. This improves the rigidity of the frame body as compared with a frame body formed of, for example, only resin and having the same thickness of the peripheral wall, and therefore, the frame body can be made smaller while improving the strength of the frame body. Therefore, the entire operation device can be miniaturized by the miniaturization of the housing.

The operation device according to the present embodiment is installed on, for example, a wall of a building, and is connected to an operation target device such as an air conditioner (not shown) via a signal line. The operation device controls the operation target device by transmitting a control signal corresponding to an operation by a user to the operation target device.

As shown in fig. 1, the operation device 100 includes a user interface apparatus 1 and a housing 10. As shown in fig. 2, the operation device 100 includes a control board 4 on which a plurality of electronic components 42 are mounted and which outputs control signals to the user interface device 1 and the air conditioner, and a base member 5 for mounting the housing 10 on a wall material (building material). The operation device 100 includes an insulating member (2 nd insulating member) 7 disposed so as to cover the periphery of the user interface device 1, an insulating sheet 8 interposed between the user interface device 1 and the control board 4, and an insulating member (3 rd insulating member) 6 covering a surface of the control board 4 opposite to the insulating sheet 8 side.

As shown in fig. 3, the operation device 100 is fixed to a wall material W and is provided in a state where a signal line L for communication with the air conditioner is connected to the upper side. Hereinafter, in the present specification, the vertical direction of the operation device 100 when it is attached to the wall material W as shown in fig. 3 is defined as the + Z direction, and the vertical direction (the floor surface F side) is defined as the-Z direction. A direction parallel to the wall material W and orthogonal to the vertical direction is referred to as an X direction, and a direction perpendicular to the wall material W is referred to as a Y direction. In the following description, the + Y direction is set to the front side and the-Y direction is set to the rear side as appropriate.

As shown in fig. 2, the user interface device 1 includes a display 11 and a touch panel 12 disposed to overlap with a front surface of the display 11. The display 11 is flat, and a display portion 11a shown in fig. 1 is provided on one surface in the thickness direction, i.e., the front surface. The display 11 is, for example, a liquid crystal display. The touch panel 12 is a resistive film type touch panel, a capacitive type touch panel, or the like. The user interface device 1 is connected to the control board 4 via a flexible wiring board 13 such as an FPC board. The user interface device 1 displays various information on the display 11 based on a control signal input from the control substrate 4 via the flexible wiring substrate 13. Further, a metal frame 111 for reinforcement is attached to the rear surface of the display 11.

The control board 4 outputs a control signal to the user interface device 1, thereby causing the display unit 11a of the user interface device 1 to display information. The control board 4 generates a control signal in accordance with an operation performed by the user on the user interface device 1, and outputs the control signal to the air conditioner. As shown in fig. 4A, the control board 4 includes a substrate 41, a plurality of electronic components 42 mounted on the rear surface of the substrate 41, a capacitor 43, a thermistor 44, and a connector 46.

The connector 46 is connected to a plug 53 connected to the tip end portions of relay leads L11 and L12 described later. The thermistor 44 is used to measure the ambient temperature of the operating device 100. The control substrate 4 calculates the ambient temperature of the operation device 100 based on the output of the thermistor 44. Then, the control board 4 generates a control signal for causing the display unit 11a of the display 11 to display information indicating the calculated ambient temperature, and outputs the control signal to the user interface device 1. The substrate 41 is formed by forming a conductive pattern on a substrate made of an insulator material such as glass epoxy. The substrate 41 is formed with a cutout 414, through

holes

411 and 412 through which the ribs 208 described later are inserted, and three through holes 413 through which the screws 91 described later are inserted.

The terminal block 52 includes a terminal block main body 521, a terminal block 522, and a screw 523 for pressing the terminal block 522 to clamp the signal line L with the terminal block 522. Relay leads L11 and L12 are connected to the two terminal plates 522, respectively. The relay leads L11 and L12 are connected via a conductive member such as solder or silver paste. Further, plugs 53 connected to the connectors 46 of the control board 4 are provided at the distal ends of the relay leads L11 and L12. The control board 4 transmits and receives control signals to and from the air conditioner via the relay leads L11 and L12 and the signal line L or receives power supply from the air conditioner in a state where the plug 53 is connected to the connector 46.

Next, a method of assembling the operation device 100 of the present embodiment will be described. First, as shown in fig. 7A and 7B, the

metal panels

31 and 32 are arranged such that the

side pieces

312 and 322 thereof overlap the

side walls

201 and 206 of the housing main body 2. Then, the

side pieces

312 and 322 of the

metal panels

31 and 32 are pressed against the

side walls

201 and 206 of the housing main body 2 using, for example, a pressing jig. Thus, the

metal panels

31 and 32 are fixed to the housing body 2 by the adhesive member 34.

Next, as shown in fig. 11, the light guide member 24 is fitted into the recess 235a of the rib 235. Then, the insulating member 7 is disposed inside the

ribs

236, 237, and 238 on the rear surface of the bottom wall 203 of the housing body 2 so that the protruding portion 711 thereof fits into the notch portion 236a of the rib 236 of the bottom wall 203.

Thereafter, as shown in fig. 12, the user interface device 1 is disposed on the rear surface of the bottom wall 203. At this time, as shown in fig. 13, the insulating member 7 is disposed so as to cover a portion of the user interface device 1 that faces the 1 st portion P1 of the

metal panels

31 and 32, that is, an outer peripheral portion of the display portion 11a of the user interface device 1. In addition, the insulating tape 33 is disposed so as to overlap the insulating member 7 in the facing direction (Y-axis direction) of the user interface device 1 and the

metal panels

31 and 32. Here, the user interface device 1 is housed in the housing 10 in a state in which the display portion 11a of the display 11 is visually recognizable from the outside of the housing 10 through the opening 205 of the bottom wall 203 of the housing main body 2, and the outer peripheral portion of the display portion 11a on the front surface of the display 11 faces the 1 st portion P1 of the

metal panels

31, 32.

Then, as shown in fig. 14, the insulating sheet 8 is fixed to the user interface device 1 by the adhesive member 82. Then, the cushioning members 81 are attached to the inside of the two openings 8a of the insulating sheet 8.

Next, as shown in fig. 15, the control board 4 is disposed in the housing 10 so that the ribs 208 of the housing main body 2 are inserted into the through

holes

411 and 412 of the control board 4. At this time, the thermistor 44 is disposed in the space S234 defined by the partition wall 234a in the housing main body 2. Thus, the control board 4 is disposed in the housing 10 in a state of being overlapped with the user interface device 1 via the insulating sheet 8 and the cushioning member 81. That is, the housing body 2 houses the user interface device 1 and the control board 4 in a state where the user interface device 1 is disposed closer to the bottom wall 203 of the housing body 2 than the control board 4.

Thereafter, as shown in fig. 16, the insulating member 6 is disposed on the rear surface of the control substrate 4 so that the rib 208 of the housing main body 2 is inserted through the hole 601e of the insulating member 6. At this time, the connector 46 of the control board 4 is inserted through the opening 601a, and the electronic component 42A of the control board 4 is inserted through the opening 601 b. Here, the slits 601c extend from the vertically lower side (-Z direction side) of the electronic component facing regions a1, a2, A3, a4, a5 to both sides in the direction (X axis direction) orthogonal to the vertical direction (Z axis direction) in a state where the operation device 100 is attached to the wall material W. Here, the electronic component facing regions a1, a2, A3, a4, and a5 are regions in which the front surface faces the

electronic components

42B, 42C, 42D, 42E, and 42F on the control board 4.

Then, the screw 91 inserted into the hole 601f of the insulating member 6 and the through hole 413 of the control board 4 is screwed into the screw hole 209a of the boss 209 of the housing main body 2. Thereby, the insulating member 7, the user interface device 1, the insulating sheet 8, the control board 4, and the insulating member 6 are fixed to the housing main body 2 by three screws 91. Then, when the base member 5 is mounted to the frame body 2, the operation apparatus 100 is completed.

Next, a method of attaching the operation device 100 of the present embodiment to the wall material W will be described. Here, a case will be described in which the base member 5 is detached from the operation device 100 in advance. First, as shown in fig. 17, the base member 5 is attached to the wall material W by screws 54. As shown in fig. 10, the screws 54 are inserted through the through

holes

511b and 511c of the base member 5, respectively. Then, as shown in fig. 10, the signal line L and the relay leads L11 and L12 are attached to the base member 5.

Next, as shown by arrow AR1 in fig. 17, the engagement claw 204a of the housing 10 is engaged with the recessed portion 513a of the base member 5. As a result, as shown in fig. 18, the housing 10 is suspended from the base member 5.

Thereafter, as shown by arrow AR2 in fig. 18, when the frame 10 is rotated with the engagement claws 204a engaged with the recessed portions 513a of the base member 5 as base points, the lower end portion of the frame 10 abuts on the hooks 515 of the base member 5. When the housing 10 is further turned in the direction of the arrow AR2, the front end 515a of the hook 515 of the base member 5 is bent upward as shown by the arrow AR 3. Then, as shown in fig. 19, when the tip end portion 515a of the hook 515 of the base member 5 is engaged with the engagement hole 202a of the frame 10, the frame 10 is fixed to the base member 5. Thus, the operation device 100 is mounted to the wall material W.

As described above, in the operation device 100 of the present embodiment, the housing 10 includes the housing main body 2 and the

metal panels

31 and 32, the housing main body 2 is formed of a non-conductive resin, the

metal panels

31 and 32 are formed of a metal having a higher elastic modulus than the resin, and the metal panels are fixed to the housing main body 2 in a state in which a part thereof is exposed to the outside of the housing 10, thereby reinforcing the housing main body 2. This improves the rigidity of the frame 10 as compared with a frame formed of, for example, only resin and having the same thickness of the peripheral wall, and therefore, the frame 10 can be made smaller while improving the strength of the frame 10. Therefore, the entire operation device 100 can be downsized due to the downsizing of the housing 10.

In the operation device 100 of the present embodiment, the control board 4 is disposed in the housing 10 in a state of being overlapped with the user interface apparatus 1 via the insulating sheet 8 and the cushioning member 81. Thus, for example, when an impact is applied to the operation device 100 from the outside when the operation device 100 is conveyed or when the operation device 100 is held and the operation is performed to attach the wall material W, the impact is absorbed by the shock absorbing member 81. Therefore, breakage of the user interface device 1 caused by external impact is suppressed.

The operation device 100 of the present embodiment includes an insulating member 6 covering the rear surface of the control board 4. This can prevent the operator from accidentally touching the control board 4 when the operator sets the operation device 100 on the wall material W. Therefore, for example, it is possible to prevent the control board 4 from being broken due to a surge current flowing through the control board 4 by static electricity accumulated in the clothes of the operator.

Further, the control board 4 of the present embodiment is formed with a notch 414. The capacitor 43 is disposed inside the notch 414. Accordingly, the control board 4 can be made thinner by the thickness of the control board 4 as compared with a structure in which, for example, the capacitor 43 is mounted on one surface of the board 41, and therefore the thickness of the housing 10 can be made thinner accordingly, and the operation device 100 can be made thinner.

The housing 10 of the present embodiment includes the 1 st portion P1 where the

metal panels

31 and 32 are exposed inside the housing 10. Further, as shown in fig. 7B, the insulating tape 33 is provided at a portion of the 1 st portion P1 of the

metal panels

31 and 32 facing the user interface device 1, and as shown in fig. 13, the insulating member 7 covers an outer peripheral portion of the display portion 11a of the user interface device 1 facing the 1 st portion P1 of the

metal panels

31 and 32. In the Y-axis direction, the insulating tape 33 is disposed so as to overlap the insulating member 7. Accordingly, electrical insulation between the

metal panels

31 and 32 and the metal frame 111 of the user interface device 1 is ensured, and thus occurrence of malfunction of the operation device 100 due to insulation breakdown between the

metal panels

31 and 32 and the metal frame 111 can be suppressed.

In addition, according to the electrical appliance safety law, the following criteria are required to be satisfied: two or more layers of sheet-like insulating members are interposed between the metal frame 111 and the

metal panels

31 and 32 of the user interface device 1, and the insulation breakdown voltage of each insulating member is equal to or higher than a predetermined voltage specified by the electrical product safety act. In contrast, in the housing 10 of the present embodiment, the insulating tape 33 and the insulating member 7 are interposed between the 1 st portion P1 of the

metal panels

31 and 32 and the outer peripheral portion of the display unit 11a facing the 1 st portion P1 in the user interface device 1. The insulation breakdown voltage of the insulating tape 33 and the insulating member 7 is equal to or higher than a predetermined voltage specified by the electrical product safety law. Accordingly, the user can use the operation device 100 with confidence because the standards specified by the electrical appliance safety law are satisfied.

The housing body 2 of the present embodiment is flat and has a box shape with one surface in the thickness direction open, and an opening 205 is formed in a projection area a0 of the user interface device 1 in the bottom wall 203 in the thickness direction (Y-axis direction) of the housing body 2. The

metal panels

31 and 32 are disposed outside the housing body 2. The thickness T2 of the 2 nd portion P2 of the casing main body 2 shown in fig. 5A is the same as the thickness T1 of the 1 st portion P1 of the

metal panels

31 and 32 shown in fig. 6A. This can reduce the thickness of the housing 10, and hence the operation device 100 can be made thin.

The insulating member 7 of the present embodiment covers the peripheral surface of the display 11 from the outer peripheral portion of the display portion 11a on the front surface of the display 11. This can extend the creepage distance between the

metal panels

31 and 32 and the metal frame 111 of the display 11, and thus has an advantage of improving the electrical insulation between the

metal panels

31 and 32 and the metal frame 111. Further, for example, when the operator mistakenly drops the operation device 100 on the floor surface F when the operation device 100 is installed on the wall material W, an impact may be applied to the operation device 100 from the outside in the X-axis direction or the Z-axis direction. In contrast, in the operation device 100 of the present embodiment, the side surface of the display 11 is covered with the insulating member 7, so that the impact applied to the display 11 from the X-axis direction or the Z-axis direction is relaxed, and therefore the breakage of the display 11 is suppressed.

As shown in fig. 6A and 6B, the

metal panels

31 and 32 of the present embodiment have an L-shaped cross section. Accordingly, the

metal panels

31 and 32 have higher rigidity than the flat metal panels, and therefore, the strength of the housing 10 can be increased as compared with a structure in which flat metal panels are attached to the bottom wall 203 or the

side walls

201 and 206 of the housing main body 2, for example.

The insulating member 6 of the present embodiment has a plurality of slits 601 c. The slits 601c extend from the vertically lower side (-Z direction side) of the electronic component facing regions a1, a2, A3, a4, a5 to both sides in the direction (X axis direction) orthogonal to the vertical direction (Z axis direction) in a state where the operation device 100 is attached to the wall material W. When the

electronic components

42B, 42C, 42D, 42E, and 42F of the control board 4 come into contact with the electronic component facing regions a1, a2, A3, a4, and a5 of the insulating member 6, the electronic component facing regions a1, a2, A3, a4, and a5 respectively flex rearward. Thus, in the state where the insulating member 6 is mounted on the rear surface side of the control board 4, the exposed areas of the

electronic components

42B, 42C, 42D, 42E, and 42F on the rear surface side are reduced, and the stress applied to the

electronic components

42B, 42C, 42D, 42E, and 42F from the insulating member 6 is relaxed. Therefore, the adhesion of foreign substances to the

electronic components

42B, 42C, 42D, 42E, and 42F is suppressed, and the damage of the

electronic components

42B, 42C, 42D, 42E, and 42F and the substrate 41 is suppressed. In the insulating member 6, no slit 601c is formed vertically above the respective electronic component facing regions a1, a2, A3, a4, and a5 in a state where the operation device 100 is mounted on the wall material W. Thus, even when dew condensation occurs on the rear surface side of the insulating member 6 and water droplets enter the electronic component facing regions a1, a2, A3, a4, and a5 from above the insulating member 6 in the vertical direction, for example, the water droplets are less likely to enter the front side of the insulating member 6. Therefore, occurrence of malfunction of the operation device 100 due to adhesion of water droplets to the control substrate 4 is suppressed.

The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. For example, the insulating member 7 may be a sheet having an outer dimension larger than the plan view of the user interface device 1, and an opening 701a having a rectangular shape in plan view may be formed in the center portion. In this case, after the insulating member 7 is covered on the front surface of the user interface device 1, a portion extending to the outer periphery of the user interface device 1 may be bent rearward along the side surface of the user interface device 1. After the user interface device 1 is covered with the insulating member 7, the insulating member may be disposed inside the

ribs

236, 237, and 238 on the rear surface of the bottom wall 203 of the housing main body 2. Alternatively, the insulating member 7 may be placed on the bottom wall 203 of the housing main body 2, and after the user interface device 1 is pushed in from behind, the portion of the insulating member 7 protruding rearward from the user interface device 1 may be cut off. According to these structures, there is an advantage that the shape of the insulating member 7 can be simplified.

In the embodiment, the example of the operation device 100 including the housing 10 having the structure in which the

metal panels

31 and 32 are exposed to the inside has been described, but the structure of the housing is not limited thereto. For example, the housing may be provided with

metal panels

31 and 32 provided on the outer wall of the resin housing body 2 and have a structure in which the

metal panels

31 and 32 are not exposed inside the housing body 2. According to this configuration, since the insulating tape 33 and the insulating member 7 can be omitted, the structure of the operation device can be simplified by reducing the number of components.

In the embodiment, the decorative property may be improved by performing the surface drawing process along the longitudinal direction on the appearance surface exposed to the outside in the state of being attached to the housing main body 2 among the

metal panels

31 and 32. Further, the

metal panels

31 and 32 may be anodized with aluminum to improve the rust prevention effect and the decorative property of the

metal panels

31 and 32. In the aluminum anodizing treatment, the

metal panels

31 and 32 can be colored, and for example, the

metal panels

31 and 32 may be colored in a silver color, a gold color, black color, or the like.

In the embodiment, the example in which the

metal panels

31 and 32 have an L-shaped cross section has been described, but the shape of the metal panels is not limited to this, and may be, for example, a flat plate.

In the embodiment, an example of the operation device of the air conditioner has been described, but the operation target device of the operation device is not limited to the air conditioner and may be other residential facility devices.

The present invention is capable of various embodiments and modifications without departing from the broad spirit and scope of the present invention. The above-described embodiments are illustrative of the present invention, and the scope of the present invention is not limited thereto. That is, the scope of the present invention is shown not by the embodiments but by the claims. Further, various modifications made within the scope of the claims and within the meaning of the equivalent invention are considered to be within the scope of the present invention.
