First Embodiment
A first embodiment of the present invention will be described using FIGS. 1 to 7. The input device 10 for a vehicle performs an input by detecting the presence or absence of the contact operation with respect to the surface of the protection panel 11. The vehicle input device 10 of the present embodiment forms a user interface for operating the air conditioner 20 mounted on a vehicle. For example, as shown in FIG. 3, the vehicle input device 10 is installed on an instrument panel 50 in a vehicle compartment, and exposes the protection panel 11 in a range in which the operator's fingers easily reach. The operator can operate the operating state of the air conditioner 20 by touching the protection panel 11. The operating state of the air conditioner 20 is notified to the operator by the display unit 12 provided on the vehicle 51.

  Display unit 12 is, for example, a liquid crystal display device. The display unit 12 is not limited to a liquid crystal display device, and other known display devices can be used. The display unit 12 displays not only the operating state of the air conditioner 20 but also, for example, map information and route guidance information as information on the navigation device. The display part 12 is arrange | positioned under the input device 10 for vehicles, as shown in FIG.

  The input device 10 for vehicle has the second film 22, the first film 21 and the protective panel 11 sequentially stacked on the light transmitting plate 26 having a light transmitting property. The protection panel 11 is provided on the outermost side of the vehicle input device 10, and the surface is an operation surface with which the operator performs a contact operation. The translucent member 26 and the protection panel 11 are made of, for example, a plate-like translucent resin material. The protective panel 11 can be subjected to, for example, coating with a light shielding paint, printing with a light shielding ink, and processing with a laser or the like to form a figure or the like on the surface.

  The first film 21 and the second film 22 form a touch switch. Each of the films 21 and 22 is formed in a film shape, and is attached to the back surface of the protection panel 11 opposite to the operation surface with a double-sided tape or an adhesive. Each of the films 21 and 22 is composed of an insulating film 23, a transparent electrode 24, a lead wire 25, and the like. The insulating film 23 is formed of a translucent thin film material such as polyethylene terephthalate or polyimide.

  The first film 21 is disposed on the back surface of the protection panel 11. The first film 21 has a rectangular shape, and has the transparent electrode 24 and the lead wiring 25. The transparent electrode 24 is a translucent conductive layer formed of a conductive polymer paint applied to the insulating film 23, for example, PEDOT. The transparent electrode 24 is disposed in the input area 27 located at the center of the first film 21. The transparent electrodes 24 are strips extending in the width direction of the first film 21, that is, in the left-right direction in FIG. 2, and a plurality of the transparent electrodes 24 are arranged at intervals in the length direction.

  From each transparent electrode 24, a lead wire 25 electrically connected to the transparent electrode 24 is connected, and the lead wire 25 is drawn to the periphery. The lead wires 25 are disposed to be gathered at the lower center of the first film 21. The lead wiring 25 is formed of a film material such as metal. The lead wiring 25 is disposed in the peripheral area 28 around the input area 27. Specifically, the lead-out wiring 25 extends in a strip shape around the peripheral region 28 around the transparent electrode 24. The surrounding area 28 is located outside the operation surface with which the operator performs a touch operation. Therefore, the surrounding area 28 can not be viewed from the operator. The lead wiring 25 is electrically connected to the capacitance measuring unit 14 of the control circuit 13.

  The second film 22 is disposed on the back surface of the first film 21 opposite to the protective panel 11. The second film 22 has a rectangular shape, and similarly to the first film 21, has the transparent electrode 24 and the lead wiring 25. The transparent electrode 24 is disposed in the input area 27 located at the center of the second film 22. The input area 27 has the same size as the input area 27 of the first film 21. The lead wiring 25 is disposed in the surrounding area 28 in the same manner as the first film 21.

  The transparent electrodes 24 are strips extending in the longitudinal direction of the second film 22, that is, in the vertical direction in FIG. 2, and a plurality of the transparent electrodes 24 are arranged at intervals in the width direction. The wiring lines 25 are drawn out from the transparent electrodes 24 respectively. The lead wires 25 are disposed to be gathered at the lower center of the second film 22. The lead wiring 25 of the second film 22 is grounded to the ground through the control circuit 13. The lead wiring 25 and the control circuit 13 are connected through a flexible printed wiring board.

  As shown in FIG. 2, the transparent electrodes 24 of the films 21 and 22 are arranged in a matrix when viewed from the front. In FIG. 2, the transparent electrodes 24 of the first film 21 and the transparent electrodes 24 of the second film 22 are hatched differently to facilitate understanding. Thereby, the transparent electrode 24 of each film generates a capacitance with the finger touching the input surface. Therefore, the contact position of the finger can be identified by identifying the transparent electrode 24 whose capacitance has changed. The capacitance generated between the finger and the transparent electrode 24 changes according to the distance from the input surface to the finger.

  In addition, a light-emitting diode (abbreviated as LED) is mounted on the light-transmissive member 26 as a light source. When the LED 29 emits light, an image showing a button or the like printed and formed on the light transmitting member 26 or the protection panel 11 appears. In other words, when the LED 29 emits light, an area functioning as a button on the protection panel 11 is specified.

  The control circuit 13 is electrically connected to the display unit 12 and the air conditioner 20 to control each unit. The control circuit 13 is also connected to the vehicle input device 10 and acquires a signal related to an input operation from the vehicle input device 10. The control circuit 13 includes a control unit 15 and a capacitance measuring unit 14.

  The capacitance measuring unit 14 measures the capacitance of each transparent electrode 24 from the signal obtained from each transparent electrode 24. The control unit 15 determines the presence of the touch operation on the protection panel 11 based on the measured change in capacitance. In other words, the control unit 15 obtains the value of the capacitance of each transparent electrode 24 calculated by the capacitance measuring unit 14, and does the obtained value of the capacitance exceed a preset threshold value? Compare whether or not. The control unit 15 determines the presence or absence of the touch operation on the protection panel 11 based on the comparison result.

  The control unit 15 executes a program stored in a storage medium to control each unit. The control unit 15 has at least one arithmetic processing unit (CPU) and a storage medium for storing programs and data. Control unit 15 is implemented by, for example, a microcomputer including a storage medium readable by a computer. A storage medium is a non-transitory tangible storage medium that non-temporarily stores computer readable programs and data. The storage medium is realized by a semiconductor memory or a magnetic disk.

  The control unit 15 is connected to another device, that is, the air conditioner 20 in the present embodiment, and mutually transmits and receives information. The control unit 15 outputs, to the air conditioner 20, a signal instructing change of the operation state of the information related to the touch operation input by the operator. In addition, the control unit 15 acquires a signal indicating the current operation state from the air conditioner 20.

  The control unit 15 is connected to the display unit 12 and controls an image displayed on the display unit 12. The control unit 15 controls the display unit 12 based on the information acquired from the air conditioner 20, and causes the display unit 12 to display the current operating state of the air conditioner 20.

  Next, control of the vehicle input device 10 will be described. When the operator contacts the operation surface of the vehicle input device 10, the contact position can be detected by the change in capacitance as described above. The control part 15 is allocated the function which operates each apparatus with which the air conditioner 20 is equipped according to a contact point. Such functions include switching the operation mode of the associated device among two, for example, a simple switching function of turning on and off, a circular switching function of switching the operation mode of the associated device among a plurality, and setting of the associated device There is an adjustment function to adjust the value.

  Next, the configuration for supporting the panel 52 will be described. The panel 52 is a generic term including the protective panel 11, the light transmitting member 26 and the films 21 and 22. The panel 52 is supported by a support member 53. The support member 53 includes a slide portion 54 and a drive portion 55.

  The slide portion 54 supports the panel 52 of the vehicle input device 10 in a plurality of positions so as to be slidably displaceable. The panel 52 is disposed so as to overlap the instrument panel 50 of the vehicle 51 as shown in FIG. 3 in the basic position. From such a basic position, the slide portion 54 slides upward. As shown in FIG. 4, when the slide displacement is gradually performed and disposed at the slide position after the slide displacement shown in FIG. 5, most of the panel 52 is opposed to the front window 51a of the vehicle 51 in the thickness direction There is. Therefore, the space 56 covered by the panel 52 in the basic position is open in the sliding position.

  In the space 56 of the instrument panel 50, as shown in FIG. 5, for example, an audio device 57 is disposed. The audio device 57 includes an insertion slot 57a for inserting a recording disc and a recording card, and an operation button 57b for various settings. Further, the upper side of the audio device 57 can be used as a storage space capable of storing small items and the like.

  The panel 52 is slidingly displaced by the drive unit 55. The drive of the drive unit 55 is controlled by the control unit 15. Drive unit 55 is realized by, for example, a motor. The rotational force of the motor is transmitted to the rack provided on the side of the panel 52 to slide and displace the panel 52.

  The slide by the slide unit 54 is executed, for example, by the operator pressing a slide switch or the like. The slide switch may be mounted on the vehicle input device 10 or may be mounted on another part. When the slide switch is operated, slide displacement from the basic position to the slide position or slide displacement from the slide position to the basic position is performed.

  Further, as shown in FIGS. 6 and 7, in the basic position, the shielding member 58 is disposed on the back side of the panel 52. In FIGS. 3 to 5, in order to show the shielding member 58 disposed on the back side of the panel 52, the shielding member 58 is hatched. The shielding member 58 is a member for concealing the space 56, and is made of an opaque material. The shielding member 58 is opposed to the panel 52 in the thickness direction (left and right direction in FIG. 6) in the basic position.

  At the slide position, the panel 52 and the panel 52 do not face in the thickness direction. The shielding member 58 is configured to be storable, and when the panel 52 is in the sliding position, the shielding member 58 is accommodated. The shielding member 58 is made of, for example, a rollable cloth material or a film material.

  In the space 56, as shown in FIG. 7, a winding unit 59 is provided at the top. The winding portion 59 biases the shielding member 58 in a winding direction by a spring force. Therefore, as the panel 52 slides upward, the shielding force of the winding portion 59 is wound up. Therefore, the shielding member 58 can be wound up without using electrical energy.

  Further, when the panel 52 is displaced downward from the sliding position, the shielding member 58 is drawn out from the winding portion 59 since the sliding displacement is performed against the spring force of the winding portion 59. As a result, when the slide position shown in FIG. 7 returns to the basic position shown in FIG. 6, the shielding member 58 and the back side of the panel 52 face each other.

  As described above, the vehicle input device 10 of the present embodiment includes the panel 52 having the light transmitting property and having the detection unit for detecting the contact of the operator, and the support member 53 for supporting the panel 52. The panel 52 is configured to be slidably displaced by the slide portion 54. Thereby, the panel 52 can be slid and displaced. Since the panel 52 has translucency, the rear side of the panel 52 can be viewed through the panel 52 even after slide displacement. Therefore, it is possible to prevent the other part from being hidden by the slide-displaced panel 52. Also, by sliding displacement, the back side of the panel 52 before sliding displacement can be used as another space 56. Therefore, it can be used as a space 56 for installing other devices, for example, the audio device 57 and a space 56 for storing accessories and the like. Thus, the installation space in the vehicle 51 can be effectively utilized by the panel 52 which has slideability which can be slid and displaced.

  In the present embodiment, the panel 52 does not face the front window 51a of the vehicle 51 in the thickness direction in the basic position, and at least a part of the panel 52 faces the front window 51a of the vehicle 51 in the thickness direction in the slide position ing. The slide position is opposite to the front window 51a, but since the panel 52 is translucent, the outside can be confirmed through the panel 52. Therefore, even if the panel 52 is slidingly displaced, it is possible to suppress blocking of the field of view.

  Furthermore, in the present embodiment, in the basic position, the opaque shielding member 58 is disposed on the back side of the panel 52. As a result, the inside of the space 56 is confirmed through the transparent panel 52, and the visibility of the panel 52 can be suppressed from being reduced. When the panel 52 is in the sliding position, at least a part of the panel 52 does not face the shielding member 58 in the thickness direction. In the present embodiment, in the sliding position, the shielding member 58 and the panel 52 do not face each other in the area not overlapping the basic position. Thus, when the panel 52 is in the sliding position, the field of view can be secured through the panel 52.

  Further, in the present embodiment, the shielding member 58 is configured to be storable, and when the panel 52 is in the sliding position, the shielding member 58 is accommodated. Thus, when the panel 52 is in the sliding position, the space 56 can be visually recognized. Therefore, the convenience can be improved.

  Furthermore, in the present embodiment, the support member 53 further includes a drive unit 55 that slides the panel 52. Thus, the panel 52 can be displaced by the drive unit 55. Therefore, the slide displacement is facilitated because the operator does not need to operate the panel 52 for the slide displacement. This can improve the convenience.

(Other embodiments)
The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and can be variously modified and implemented without departing from the spirit of the present invention.

  The structures of the aforementioned embodiments are merely illustrative, and the scope of the present invention is not limited to the scope of these descriptions. The scope of the present invention is shown by the statement of a claim, and also includes the meaning of a statement of a claim, an equivalent meaning, and all the changes within the range.

  In the first embodiment described above, the shape of the transparent electrode 24 is a strip, but the shape is not limited to such a shape. The capacitance may be changed by the contact so long as the contact position can be detected. Moreover, as a detection part which detects a contact, it does not restrict to the system which uses an electrostatic capacitance, and may detect a touch by a pressure-sensitive type.

  In the first embodiment described above, the panel 52 is configured to slide and displace upward from the basic position, but the invention is not limited to this. For example, the panel 52 may be configured to slide downward from the basic position. When the slide displacement is downward, the display screen of the display unit 12 is overlapped, but since the panel 52 has translucency, the display screen can be confirmed through the panel 52. Therefore, even in the case of sliding displacement downward, it is possible to suppress that the panel 52 interferes with the confirmation of the display on the display unit 12. In addition, it may be configured to slide and displace from the basic position toward the front passenger seat, that is, to the left. Even with such a configuration, the panel 52 has translucency, so that it is possible to suppress giving a passenger in the passenger seat a sense of oppression.

  Although the shielding member 58 is provided in the first embodiment described above, the shielding member 58 may not be provided. Further, the shielding member 58 may be a partially translucent member, for example, a partially translucent member such as frosted glass but low translucency. In such a configuration, for example, a light source may be disposed in the space 56, and the panel 52 may emit light by the light transmitted through the shielding member 58 by emitting light in the space 56. The shielding member 58 may be configured by a half mirror. This can improve the appearance.

  In the first embodiment described above, the panel 52 is slidingly displaced by the driving unit 55. However, the present invention is not limited to the sliding displacement by the driving unit 55, and may be manually slidingly displaced. Therefore, for example, the panel 52 and the support member 53 may be configured as a slide door, and the panel 52 may be configured to be slidable manually.

  In the first embodiment described above, the shielding member 58 is configured to slide and displace together with the panel 52. However, the present invention is not limited to such a configuration, and may be configured to independently slide and displace. For example, the panel 52 is configured to be slide-displaced by the drive unit 55, and the shielding member 58 may be configured to be manually slid like a roll curtain, and configured to be foldable by being bellows-like and manually foldable It is also good. Further, the panel 52 and the shielding member 58 may be driven by the common drive unit 55, or may be driven by separate drive units 55.

  In the first embodiment described above, the functions implemented by the control circuit 13 may be implemented by hardware and software different from those described above, or a combination thereof. The control circuit 13 may, for example, communicate with other control devices, which may perform some or all of the processing. When the control circuit 13 is realized by an electronic circuit, it can be realized by a digital circuit including a number of logic circuits or an analog circuit.
