Description

  The present invention relates to a touch switch for detecting a touch with a user's fingertip or the like, and more particularly to a touch switch capable of preventing malfunction.

  Conventionally, vehicles and buildings have been provided with switches that can be associated with predetermined operations (functions) such as switching on / off of interior lights and opening / closing of an electric power window. By selectively operating, a target operation is executed.

  By the way, in recent years, touch switches (touch panels) that electrically detect a user's touch on a screen instead of a mechanical switch that mechanically detects a user's operation are rapidly spreading. Application to the operation of air conditioners in Japan is under consideration. This touch switch detects an electrical change when a user's finger, which is a conductor, contacts a button displayed on a flat screen. For example, Japanese Patent Application Laid-Open No. 2009-75656 discloses a touch switch. (Patent Document 1) and the like.

  However, in Patent Document 1, since the button of the touch switch is displayed on a screen that is sufficiently large with respect to the size of the finger, the user may inadvertently touch when performing other work. As a result, there is a risk of unintended operations.

The presence or absence and contact position of the conductor to be detected with respect to the conductive member via the dielectric layer is detected.

  According to the second aspect, since the conductor to be detected is indirectly in contact with the conductive member via the dielectric layer, wear and deterioration of the conductive member are prevented, and durability is improved. . In addition, even when the dielectric layer is interposed between the conductive member and the detected conductor by applying an AC voltage, the current is substantially reduced between the conductive member and the detected conductor based on the capacitance. And the presence / absence of contact and the contact position are detected effectively.

  According to a third aspect of the present invention, in the touch switch described in the first aspect, a direct-current voltage is applied to the conductive member, and direct contact of the detected conductor with respect to the conductive member is performed. Presence / absence and contact position are detected.

  According to the 3rd aspect, when a to-be-detected conductor contacts a conductive member directly, a DC voltage can be used and the structure of a power supply can be simplified.

  According to a fourth aspect of the present invention, in the touch switch described in any one of the first to third aspects, the conductive member is formed of a conductive resin.

  As shown in the fourth aspect, when the conductive member is formed of a conductive resin, the degree of freedom of the shape of the conductive member can be increased by molding. Accordingly, even when a three-dimensional shape is required for the conductive member, the conductive member can be easily formed into a predetermined shape.

  According to a fifth aspect of the present invention, in the touch switch described in any one of the first to third aspects, the conductive member is formed of a conductive paint.

  According to a sixth aspect of the present invention, in the touch switch described in any one of the first to fifth aspects, a displacement amount and a displacement direction of the contact displacement of the conductor to be detected on the conductive member are: It is specified by continuously detecting the presence / absence of contact and the contact position.

  According to the sixth aspect, since the movement of the conductor to be detected on the conductive member is detected, one operation can be performed by associating the operation with the change in the contact position as well as the presence or absence of the contact. More operations can be realized with the touch switch.

  According to the present invention, the partitioning convex portion having electrical insulation is provided on the operation surface of the conductive member that comes into contact with the conductor to be detected, and the operation surface is partitioned by the partitioning convex portion. Thereby, in the touch switch according to the present invention, an unintended contact of the conductor with the operation surface is avoided, and an intentional operation (input) is selectively accepted.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a touch switch 10 as one embodiment of the present invention. The touch switch 10 is provided on the upper surface of the armrest 12 provided in the door portion of the automobile, and serves as an input interface for opening and closing the vehicle window.

  More specifically, as shown in FIGS. 2 and 3, the touch switch 10 includes a base body 14 made of an insulating material and a conductive member 16 superimposed on the surface thereof. The base 14 is made of an electrically insulating material such as a synthetic resin. In addition, although the base | substrate 14 is shown by the flat plate shape in the figure, a shape is not specifically limited.

  The conductive member 16 is formed of a conductive material having a high electrical conductivity. In this embodiment, the conductive member 16 is formed of a conductive resin material obtained by mixing a conductive filler such as carbon black with a synthetic resin material. The conductive member 16 is superimposed and fixed on the upper surface of the base 14. The conductive member 16 is made of a rubber-based conductive paint obtained by mixing carbon black as a conductive filler with a prepared rubber compound added with an organic solvent, and further adding a printing solvent. It may be formed by printing on the upper surface of the substrate 14 in a predetermined shape by a method such as printing, flexographic printing, gravure printing, pad printing, or lithography. Furthermore, the conductive member 16 can be formed of a conductor such as a metal plate.

  In addition, the conductive member 16 has a lower surface overlapped and fixed to the upper surface of the base 14 and an upper surface serving as an operation surface 18 so that contact of a detected conductor to be described later can be detected. . In addition, although the operation surface 18 of the present embodiment is a flat surface having almost no unevenness, the shape of the operation surface is not particularly limited, and may be inclined with respect to a horizontal plane or a vertical plane, for example. Alternatively, it may be curved and recessed in a concave shape.

  A first AC power supply 20 is connected to one end of the conductive member 16, and an AC voltage is applied from the first AC power supply 20 to one end of the conductive member 16. On the other hand, a second AC power source 22 is connected to the other end of the conductive member 16, and an AC voltage is applied from the second AC power source 22 to the other end of the conductive member 16. By these first and second AC power supplies 20 and 22, voltages having the same phase and the same potential are applied to the conductive member 16 from two locations. When the finger 48 described later is in a non-contact state, the conductive member 16 has a current. Does not flow.

  The first detection resistor 24 is connected to one end of the conductive member 16. The first detection resistor 24 is disposed on a connection path between one end of the conductive member 16 and the first AC power supply 20 and is electrically connected to the conductive member 16 and the first AC power supply 20. ing. On the other hand, a second detection resistor 26 is connected to the other end of the conductive member 16. The second detection resistor 26 is disposed on a connection path between the other end of the conductive member 16 and the second AC power supply 22, and is electrically connected to the conductive member 16 and the second AC power supply 22. Has been. The first and second detection resistors 24 and 26 have the same resistance value (r).

  Further, a first voltmeter 28 for measuring the voltage applied to the first detection resistor 24 is provided, and a first voltage meter for measuring the voltage applied to the second detection resistor 26 is provided. Two voltmeters 30 are provided. Then, by confirming the energization state of the conductive member 16 based on the measured values of the first and second voltmeters 28 and 30, the presence or absence of contact of the conductor to be detected, which will be described later, the contact position, etc. Is to be detected.

  Further, the first and second voltmeters 28 and 30 are connected to the processing device 32 by wire or wirelessly. The processing device 32 includes a contact confirmation unit 34 that determines the presence / absence of contact of the detected conductor to the conductive member 16 based on the measurement results of the first and second voltmeters 28 and 30, and a contact confirmation unit 34. When the contact of the conductor to be detected with the conductive member 16 is confirmed by the operation, the operation specifying means 36 for specifying the contact position and the change (operation) of the contact position, and the control according to the operation specified by the operation specifying means 36 Control signal output means 38 for outputting a signal to a vehicle window opening / closing device (not shown).

Further, a partitioning convex portion 40 is provided on the operation surface 18 of the conductive member 16. The partitioning convex portion 40 is formed of a material having electrical insulation, and is provided so as to overlap the operation surface 18 of the conductive member 16 and protrude upward from the operation surface 18. Further, the partitioning convex portion 40 has a sufficiently large thickness dimension as compared with a dielectric layer 46 described later, and from the operation surface 18 of the conductive member 16 in the portion where the partitioning convex portion 40 is provided. The distance to the surface of the dielectric layer 46: d ₁ is the distance from the operation surface 18 of the conductive member 16 to the surface of the dielectric layer 46 in the portion where the partitioning convex portion 40 is not provided (the formation portion of the slit 42 described later). Distance: sufficiently larger than d ₂ (d ₁ > d ₂ ).

  Furthermore, a slit 42 is formed through the partitioning convex portion 40. The slit 42 is a rectangular hole that penetrates the partitioning convex portion 40 in the vertical direction and gradually decreases as it goes downward. In other words, the partitioning convex portion 40 of the present embodiment has an annular plate shape having a rectangular central hole, and the central hole is a slit 42. The operation surface 18 of the conductive member 16 is partitioned by the partitioning convex portion 40, and a portion of the operation surface 18 that is exposed through the slit 42 without being covered by the partitioning convex portion 40 is defined as the detection surface 44. By inserting the finger 48 into the slit 42, the finger 48 can come into contact with the detection surface 44 without going through the partitioning convex portion 40. Although the width dimension of the slit 42 is not particularly limited, it is desirable that the finger 48 can be inserted and that the other part of the human body such as a palm or an arm cannot be inserted. Preferably, for example, the width is set to be 1 cm or more and 3 cm or less in the narrowest lower opening.

  The upper surface of the partitioning convex portion 40 and the detection surface 44 of the conductive member 16 are covered with a dielectric layer 46. The dielectric layer 46 is a thin layer formed of a dielectric synthetic resin material or the like, and preferably has resistance to abrasion, erosion under an atmosphere, and the like. By providing such a dielectric layer 46, the finger 48 is brought into indirect contact with the detection surface 44 via the dielectric layer 46. The dielectric layer 46 may be provided only on the detection surface 44 of the conductive member 16, and does not necessarily have to extend to the partitioning convex portion 40. The dielectric layer 46 may be formed integrally with the partitioning convex portion 40. In this case, the thick portion functions as the partitioning convex portion due to the difference in thickness and the thin portion is the dielectric layer. Function as.

As shown in FIG. 4, when the finger 48 is inserted into the slit 42 and contacts the detection surface 44 of the conductive member 16 through the dielectric layer 46, the conductive member 16 is grounded through the human body including the finger 48. Therefore, currents I ₁ and I ₂ flow through the conductive member 16 and the first and second detection resistors 24 and 26. In the present embodiment, the dielectric layer 46 is provided between the finger 48 and the conductive member 16. However, since an AC voltage is applied to the conductive member 16, the conductive member 16 and the finger 48 are used as electrodes. The capacitor is configured so that a current flows between the conductive member 16 and the finger 48. In short, the touch switch 10 of this embodiment is a capacitive coupling type.

When currents I ₁ and I ₂ flow through the first and second detection resistors 24 and 26, the first and second detection resistors 24 and 26 in the first and second voltmeters 28 and 30. The voltage values Vm ₁ and Vm ₂ corresponding to the current flowing through are measured. And the contact confirmation means 34 of the processing apparatus 32 is the finger 48 (with respect to the electrically-conductive member 16) when each measured value: Vm1, Vm2 of the _1st , _2nd voltmeters 28 and 30 is more than a predetermined numerical value. The contact of the detected conductor) is detected. In addition, the contact confirmation means 34 determines whether the measured value of the 1st, 2nd voltmeters 28 and 30 is more than a preset threshold value, for example, Comprising: A measured value is more than a threshold value. Is determined, the contact of the finger 48 with the detection surface 44 of the conductive member 16 is detected.

Then, when contact of the finger 48 with the detection surface 44 of the conductive member 16 is detected, the operation specifying means 36 of the processing device 32 causes the finger 48 to move based on the measurement values of the first and second voltmeters 28 and 30. The contact position with respect to the detection surface 44 is specified. That is, as shown in FIG. 4, when the finger 48 comes into contact with an intermediate portion of the conductive member 16 having an overall resistance value of R, the conductive member 16 as a resistor has one end (in FIG. 4). , The left end) to the contact position of the finger 48 (the resistance value is R ₁ ), and the second resistor 52 from the other end (the right end in FIG. 4) to the contact position of the finger 48. (The resistance value is substantially R ₂ ). Resistance of the first resistor 50: the R _1, the resistance value of the second resistor 52: the ratio of R ₂ is, the distance from one end of the conductive member 16 to the contact position of the finger 48, the conductive Since the ratio of the distance from the other end of the member 16 to the contact position of the finger 48 is substantially the same, the contact position of the finger 48 with respect to the conductive member 16 is specified by determining the ratio of R ₁ and R _2. The In addition, FIG. 5 shows a state where the finger 48 is in contact with the conductive member 16 as an electric circuit diagram.

  Note that the measurement of the voltage value by the first and second voltmeters 28 and 30 is repeated at predetermined time intervals, and the operation specifying means 36 continuously detects the change in the contact position of the finger 48 with respect to the conductive member 16. is doing. Thereby, when the finger 48 is moved while being in contact with the surface (detection surface 44) of the conductive member 16, the displacement direction and the displacement amount of the finger 48 are specified.

  When the operation specifying unit 36 detects the contact position of the finger 48 or the movement while in contact, the control signal output unit 38 of the processing device 32 is in contact with the detection position 44 or the detection surface 44 of the finger 48. A control signal corresponding to the amount and direction of movement is output to the vehicle device. The device controlled by the operation of the touch switch 10 is not particularly limited, but in the present embodiment, for example, a vehicle window opening / closing device (not shown) is controlled, and an input to the touch switch 10 is performed. The opening / closing operation of the car window is executed according to the operation. In this embodiment, by moving the finger 48 in the longitudinal direction of the slit 42 while contacting the detection surface 44, the opening operation and the closing operation are performed according to the moving direction (left direction or right direction in FIG. 2). At the same time, the opening / closing operation amount of the vehicle window is set according to the amount of movement, and is output as a control signal from the control signal output means 38 to the opening / closing device of the vehicle window.

  On the other hand, when the human body including the finger 48 touches the upper surface of the partitioning convex portion 40, a capacitor is formed using the conductive member 16 and the finger 48 as electrodes, as in the case where the finger 48 is inserted into the slit 42. The distance between the conductive member 16 and the finger 48 is greater than when the finger 48 is in contact with the detection surface 44 because the partitioning convex portion 40 is interposed therebetween. Therefore, compared with the case where the finger 48 is in contact with the detection surface 44, the electric capacity is reduced, and the current flowing through the first and second detection resistors 24, 26 is reduced. As a result, the measurement values of the first and second voltmeters 28 and 30 become less than a preset threshold value, and the contact confirmation unit 34 determines that the finger 48 is not in contact with the conductive member 16. As described above, in the touch switch 10, only contact between the finger 48 and the detection surface 44 of the conductive member 16 through the slit 42 is selectively detected.

  Thereby, in the touch switch 10, the erroneous opening / closing operation | movement of the vehicle window by the unintended contact to the operation surface 18 is prevented. That is, by providing the partitioning convex portion 40 on the operation surface 18, unintentional contact with the operation surface 18 is prevented by the partitioning convex portion 40, and malfunction is prevented. In particular, in the present embodiment, since the partitioning convex portion 40 is provided so that the exposure of the operation surface 18 is limited to the narrow slit 42 to which the finger 48 is inserted, inadvertent contact is caused. Avoided more effectively.

  On the other hand, when the opening / closing of the car window is intentionally operated, the finger 48 is inserted into the slit 42 that is always opened, and the finger 48 is slid while being in contact with the operation surface 18 (detection surface 44), thereby causing erroneous contact. It can be easily operated without requiring extra work such as opening the prevention cover. Moreover, since the detection surface 44 is provided on the bottom surface of the recessed portion by the slit 42, the position of the detection surface 44 can be visually confirmed by searching the upper opening of the slit 42 with the tactile sensation of the fingertip. You can grasp without doing.

  In the present embodiment, in the capacitively coupled touch switch 10, the distance between the electrodes of the capacitor configured with the finger 48 and the conductive member 16 as an electrode is changed depending on the presence or absence of the partitioning convex portion 40, thereby It is possible to determine whether or not the operation portion is a contact by varying the magnitude of the current flowing depending on the contact. In this way, by providing the partitioning convex portion 40 formed of an insulating material on the operation surface 18, it is possible to accurately determine whether or not the detection surface 44 is in contact with a simple structure.

  Further, if the conductive member 16 is formed of a conductive resin, the degree of freedom in molding is increased by molding the conductive member 16 itself, and the conductive member 16 having a target shape can be easily obtained. On the other hand, if the conductive member 16 is formed of a conductive paint, the conductive member 16 along the shape of the base 14 is formed. Therefore, the base 14 is formed of a general synthetic resin having a large degree of freedom in shape. The conductive member 16 having a target shape can be easily obtained.

  In addition, since the detection surface 44 is covered with the dielectric layer 46, deterioration and wear of the conductive member 16 due to repeated contact and sliding of the finger 48 are prevented, and durability of the conductive member 16 is improved. . In addition, since an AC voltage is applied to the conductive member 16 from the first and second AC power supplies 20 and 22, the finger 48 contacts the conductive member 16 through the dielectric layer 46 based on the capacitance. Is effectively detected.

  In the present embodiment, the example in which the vehicle window is opened and closed by sliding the finger 48 with respect to the detection surface 44 of the touch switch 10 is shown. For example, the finger is placed at one end of the detection surface 44 in the longitudinal direction. The vehicle window may be opened by the contact of 48, and the vehicle window may be closed by the finger 48 contacting the other longitudinal end of the detection surface 44. In short, the touch switch may detect the sliding of the conductor to be detected on the operation surface and output a control signal corresponding to the direction and amount of sliding, or may detect the operation surface. The contact position of the conductor may be detected and a control signal corresponding to the contact position may be output.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited by the specific description. For example, although the capacitive coupling type touch switch 10 is shown in the embodiment, the scope of application of the present invention is not limited to the capacitive coupling type touch switch. It can also be applied to touch switches. Specifically, as shown in FIG. 6, the resistance-coupled touch switch 60 is configured such that the dielectric layer 46 is removed from the touch switch 10 shown in the embodiment, and the first and second layers are used. The direct current power sources 62 and 64 are employed in place of the first and second alternating current power sources 20 and 22, and the conductive member 16 has a structure in which a direct current voltage is applied. In such a resistance coupling type touch switch 60, the finger 48 is inserted into the slit 42 and brought into direct contact with the conductive member 16, and the conductive member 16 is grounded through the human body. And the contact of the finger 48 with the conductive member 16 and the contact position are detected. On the other hand, when the finger 48 comes into contact with the conductive member 16 via the partitioning convex portion 40, a direct current voltage is applied, so that the current is not flown by being insulated by the partitioning convex portion 40, and contact is detected. Not. In this manner, the presence or absence of contact of the detected conductor (finger 48) with the conductive member 16 is also detected by the resistance-coupled touch switch 60. Further, since the power supplies 62 and 64 for applying a DC voltage can be employed, the power supply circuit can be simplified. Note that the method for detecting the contact position is the same as that of the capacitively coupled touch switch 10 shown in the above embodiment, and thus the description thereof is omitted here. Moreover, about the member and site | part substantially the same as the said embodiment, description is abbreviate | omitted by attaching | subjecting the same code | symbol in a figure.

  Further, the shape of the partitioning convex portion is not particularly limited, and for example, a partitioning convex portion 72 such as the touch switch 70 shown in FIG. 7 may be employed. That is, in the touch switch 70, a plurality of partitioning convex portions 72 having a straight ridge shape are arranged in parallel at a predetermined interval on the operation surface 18 of the conductive member 16. Detection surfaces 74 for detecting contact of the finger 48 are provided between the portions 72 and 72, respectively. Even in the touch switch 70 having such a structure, unintentional contact of the finger 48 with the operation surface 18 is prevented by the partitioning convex portion 72. Further, in the touch switch 70 of the present embodiment, since the operation surface 18 is divided by the partitioning convex portions 72 and a plurality of detection surfaces 74 are provided, an operation corresponding to which detection surface 74 is touched. Can be different. In addition, since the operation surface 18 is partitioned by the partitioning convex portions 72 and partitioned into a plurality of detection surfaces 74, the intended operation can be easily performed by tactile sensation without requiring visual inspection. Note that the position of the detection surface 74 can be more easily grasped by tactile sensation, for example, by changing the shape of the partitioning convex portion 72. 7 and 8, illustration of the power source, the detection resistor, the voltmeter, and the like is omitted.

  Furthermore, for the partitioning convex portion, for example, a protruding shape such as a hemispherical shape can be adopted in addition to the plate shape or the ridge shape. In short, the shape of the partitioning convex portion is not particularly limited as long as it is made of an electrically insulating material and protrudes from the operation surface 18 to prevent unintended contact with the operation surface 18.

  Furthermore, as the partitioning convex portion, for example, a partitioning convex portion 82 such as the touch switch 80 shown in FIG. 8 may be employed. That is, the touch switch 80 employs a partitioning convex portion 82 including a window portion 84 that has a cross shape when viewed in the vertical direction in which two slits are combined so as to be orthogonal to each other. 18, a portion exposed through the window portion 84 is a detection surface 86. Further, voltages are applied to the conductive member 16 from four locations, and the input to the detection surface 86 is detected in two directions orthogonal to each other. If the partitioning convex portion 82 having the window portion 84 and the application of voltages from four locations to the conductive member 16 are employed in combination, the input to the detection surface 86 can be detected in two directions orthogonal to each other. it can. As is clear from the above, the voltage applied to the conductive member 16 is not necessarily limited to two places. For example, the voltage is applied from four places such as the touch switch 80 described above and is two-dimensional (on a plane). The contact position may be specified. The shape of the window is not particularly limited, and may be a T shape, a king shape, or the like.

  In addition, the conductor to be detected that contacts the detection surface 44 is not necessarily the finger 48, and the conductive state of the conductive member 16 is changed by the contact of the conductor to be detected, and the conductive member 16 of the conductor to be detected is changed. It is only necessary to detect the contact. Specifically, for example, a touch pen formed of a conductive material can be employed as the detected conductor.

  In addition, the device controlled by the operation of the touch switch is not limited to the opening / closing device of the vehicle window. For example, an air conditioner, an audio system, a door lock opening / closing device, a control device of the vehicle compartment light, etc. are touched. It may be controlled by operating a switch.

  Furthermore, in the said embodiment, although the touch switch 10 was provided in the armrest 12 of the door part of a motor vehicle, a touch switch is provided in the vehicle interior wall surface of the roof of a motor vehicle, for example, and turns on / off a vehicle interior light. May be used as an input interface for operating an air conditioner or an audio system provided on the instrument panel. Furthermore, the touch switch of the present invention is not necessarily used only for automobiles, and can be applied to lighting switches for houses, for example.
