Description

  The present invention relates to a combination switch device.

  As a conventional technique, a movable part position detection system including a movable part, a light emitting element and a light receiving element facing each other, and a light shielding plate arranged between the light emitting element and the light receiving element and interlocking with the movable part is known. (For example, refer to Patent Document 1).

  The light shielding plate is formed with a transmission opening having a different opening area corresponding to the moving position of the movable part. The moving part position detection system detects the moving position of the moving part on the basis of the change in the amount of light because the amount of light entering the light receiving element through the transmission opening corresponding to the moving position of the moving part changes.

  However, in the conventional movable part position detection system, as the moving position of the movable part to be detected increases, the types of opening areas of the transmission openings increase, and therefore it is necessary to detect a minute light amount change. Therefore, the movable part position detection system requires a highly accurate light-emitting circuit and light-receiving circuit in order to detect a minute change in the amount of light, resulting in a high cost.

  An object of the present invention is to provide a combination switch device that can be manufactured at a low cost while being able to detect a large number of operation positions of an operation unit with a single light receiving unit.

  One embodiment of the present invention includes an operation unit operable in a first direction and a second direction substantially orthogonal to the first direction, and an operation in the second direction performed on the operation unit in a third direction. A light-transmitting shielding part having a transmission region through which light is transmitted or transmitted and a shielding region in which light is shielded; a light-emitting unit that emits light toward the light-transmitting shielding unit; and the operation A light receiving unit that receives the light emitted from the light emitting unit through the transmission region of the light transmission shielding unit that is displaced by the operation in the first and second directions performed on the unit, and a light reception unit that receives the light. And a determination unit that determines an operation position of the operation unit based on the amount of the emitted light.

  According to the present invention, it is possible to manufacture at a low cost while being able to detect a large number of operation positions of the operation unit with one light receiving unit.

  The turn switch device 1 mainly includes an operation lever 12 as an operation unit operable in a first direction and a second direction substantially orthogonal to the first direction, and a second direction formed on the operation lever 12. The operation is converted into the displacement in the third direction, and the light is transmitted toward the shutter unit 18 as a light transmission shielding unit having a transmission region through which light passes or transmits and a light transmission shielding unit. The first to fourth light emitting units 21 to 24 that emit light and the transmission region of the shutter unit 18 that is displaced by the operation in the first and second directions applied to the operation lever 12 are used. The light receiving unit 26 that receives the light emitted from 21 to 24 and the determination unit 32 that determines the operation position of the operation lever 12 based on the light amount of the light received by the light receiving unit 26 are schematically configured. Yes.

  Here, the first direction is, for example, a direction in which the operation lever 12 is operated to the operation positions “CR” to “CL” illustrated in FIG. The second direction is, for example, a direction in which the operation lever 12 is operated to the operation positions “Hi” to “P” illustrated in FIG. The third direction is, for example, the directions of arrows C and D shown in FIG.

  As shown in FIGS. 2A and 2C, the operation lever 12 has first and second convex portions 122 a and 122 b on both side surfaces of the end portion 120.

  Further, as shown in FIGS. 2A to 2C, the shutter portion 18 corresponds to a base portion 18 </ b> A that supports the shutter 180 in which a transmission region and a light shielding region are formed, and a side surface of the end portion 120 of the operation lever 12. The first and second side portions 182a and 182b provided on the base portion 18A, the first guide portion 183a provided on the first side portion 182a and into which the first convex portion 122a is inserted, 2 and a second guide part 183b into which the second convex part 122b is inserted. The first convex part 122a is guided to the first guide part 183a and the second convex part 122b is inserted into the second side part 182b. When the second convex portion 122b is guided by the guide portion 183b, the guide portion 183b is displaced in the third direction. Note that the first and second convex portions 122a and 122b may be formed by pins inserted into through holes formed in the end portion 120, for example.

  As shown in FIG. 2A, the connecting portion of the operation lever 12 and the shutter portion 18 is covered by the support portion 16. The support portion 16 is configured so that, for example, the base portion 18A of the shutter portion 18 can slide in the directions of arrows C and D.

  The turn switch device 1 includes a light guide 28 as a light guide unit that guides light emitted from the first to fourth light emitting units 21 to 24 to the light receiving unit 26. The light guide 28 may be omitted when the light receiving unit 26 can be disposed at a position facing the first to fourth light emitting units 21 to 24 via the shutter 180 of the shutter unit 18.

(About the control lever)
FIG. 3A is a schematic view of the turn switch device in the neutral position according to the embodiment of the present invention as viewed from above, and FIG. 3B shows the operation lever operated from the neutral position to the operation position “L” direction. FIG. 4C is a schematic diagram of the turn switch device when the operation lever is operated from the neutral position to the operation position “R” direction. 3A to 3C omit the light guide 28, the substrate 20, and the like for the sake of explanation.

  For example, as shown in FIGS. 1 and 3A to 3C, the operation lever 12 is configured to rotate around the rotation support shaft 14, and as shown in FIG. “N” as “N”, and “L” and “CL” in the upper direction of FIG. 1, and as shown in FIG. 3C, there are five operation positions of “R” and “CR” in the lower direction of FIG. . Further, for example, when the operation lever 12 is operated in the upward direction in FIG. 1, the operation lever 12 is displaced in the direction of arrow A shown in FIG. It is displaced in the direction of arrow B shown in FIG.

  Further, for example, as shown in FIG. 2A, the operation lever 12 is configured to be operable in a direction substantially orthogonal to the operation position shown in FIG. 1, and the dimmer operation allows the operation lever 12 to move from the neutral position “Lo” to FIG. There are three patterns of operation positions: “P” in the upward direction of “a” and “Hi” in the downward direction of FIG. When viewed from the operator, the operation lever 12 can be operated to the operation position “P” when operated to the operator side, and can be operated to the operation position “Hi” when operated to the side away from the operator.

  Here, “N” is an operation position where the direction indicator or the like is not lit, “L” is an operation position where the left direction indicator flashes, and “CL” is a left direction instruction. This is the operating position in which the left cornering lamp lights up as the device blinks. “R” is an operation position where the right direction indicator flashes, and “RL” is an operation position where the right direction indicator flashes and the right cornering lamp is lit. The function assigned to the operation position of the operation lever 12 is not limited to the above.

  “Lo” is an operation position in which the optical axis of the headlight is directed downward (low beam). The headlight (low beam) turns on, for example, a rotation switch provided at the tip of the operation lever 12 or outside the vehicle. It shall be lit by automatic lighting based on the illuminance etc. “P” is an operation position where the optical axis of the headlight alternates upward and downward. Further, “Hi” is an operation position where the optical axis of the headlight is directed upward (high beam). The function assigned to the operation position of the operation lever 12 is not limited to the above. Further, the operation positions “P” and “Hi” can be operated at other operation positions “CL” to “CR” of the operation lever 12, and in particular, the operation position “P” moves the operation lever 12 to the operation position. After the operation to “P”, the operation lever 12 is returned to the operation position “Lo” which is a neutral position.

(About support part)
For example, as shown in FIG. 2A, the support portion 16 has a box shape in which an opening is formed at one end and a part of the bottom, and the end 120 of the operation lever 12 is within the opening of the end. Has been inserted. Moreover, the shutter part 18 is comprised so that it may displace along opening of the bottom part of the support part 16, for example.

  A convex portion 160 is formed on the upper surface 16a of the support portion 16 as shown in FIG. The convex portion 160 is inserted into a concave portion formed inside the main body 10 of the turn switch device 1, and the operation lever 12 and the shutter portion 18 rotate using the convex portion 160 as a rotation support shaft 14.

  FIG. 4A is a schematic view of the turn switch device as viewed from the side in the neutral position “Lo” according to the embodiment of the present invention, and FIG. 4B shows the operation lever from the neutral position to the operation position “P”. It is the schematic of a turn switch apparatus when operating to a direction, (c) is the schematic of a turn switch apparatus when operating an operation lever from the neutral position to the operation position "Hi" direction.

  For example, as shown in FIGS. 2A and 4A, the first and second convex portions 122a and 122b of the end portion 120 of the operation lever 12 are inserted into the side surfaces 16c and 16d of the support portion 16, respectively. First and second guide portions 183a and 183b are formed.

  As shown in FIGS. 4B and 4C, the shutter portion 18 includes first and second convex portions 122a of the end portion 120 that are generated when the operation lever 12 is operated in the “P” and “Hi” directions. Due to the displacement of 122b, it is displaced in a plane in the directions of arrows C and D shown in FIG. 2A while being guided by the first and second guide portions 183a and 183b. The planar displacement of the support unit 16 is performed, for example, in a plane parallel to the substrate 20 on which the light receiving unit 26 and the like are arranged.

  For example, when the operation lever 12 is operated upward ("P" direction) in FIG. 2A, the shutter portion 18 is displaced in the direction of arrow C shown in FIG. 2A (FIG. 4B). 2), when the operation lever 12 is operated in the downward direction ("Hi" direction) in FIG. 2 (a), it is displaced in the direction of arrow D shown in FIG. 2 (a) (see FIG. 4 (c)). .

(About the shutter part)
FIG. 5 is a top view of the shutter of the shutter unit according to the embodiment of the present invention. For example, as shown in FIG. 5, the shutter 180 of the shutter unit 18 is formed on a plate-shaped substrate with a shielding region 180 a that shields light, and a slit 180 b and an opening 180 c as a transmission region through which light passes. ing.

  The shielding area 180a is an area other than the transmission area in the shutter 180, for example. It is assumed that light emitted from the first to fourth light emitting units 21 to 24 cannot pass through or pass through the shielding region 180a.

  For example, when the determination unit 32 determines that the transmittance of the light received by the light receiving unit 26 is lower than 50%, the determination unit 32 determines that the light amount is zero. Therefore, the amount of light emitted toward the shielding region 180a is 0, and this state is referred to as state 3 shown in FIG.

  The transmission region has at least one slit 180b, and the first to sixth slit portions 181 to 186 having a large attenuation width of the amount of light emitted from the first to fourth light emitting portions 21 to 24, and the first It comprises an opening 180c in which the attenuation amount of the amount of light emitted from the first to fourth light emitting units 21 to 24 is smaller than that of the first to sixth slits 181 to 186. Note that the numbers of the first to sixth slit portions 181 to 186 and the opening portion 180 c are not limited to the above, and increase or decrease depending on the operation position of the operation lever 12.

  For example, the slit 180b forms first to sixth slit portions 181 to 186 by arranging a predetermined number at equal intervals. The slit 180b is an opening having a rectangular shape, but is not limited to this, and is formed by patterning the surface of a material having a different shape, a material in which a light transmitting material is embedded, or a light transmitting material. The opening 180c may be the same.

  The light emitted from the first to fourth light emitting units 21 to 24 passes or passes through the first to sixth slits 181 to 186, but the width of the slit 180b It is assumed that the interval, shape, etc. are adjusted.

  For example, when the determination unit 32 determines that the transmittance of the light received by the light receiving unit 26 is 50% or more and lower than 80%, the light amount is determined to be 0.5. Therefore, the amount of light that has passed through or transmitted through the first to sixth slit portions 181 to 186 is assumed to be 0.5, and this state is referred to as state 2 shown in FIG. The transmittances of the first to sixth slit portions 181 to 186 are not limited to 50%, and may be changed according to the number of operation positions of the operation lever 12, for example. For example, more operation positions can be detected by forming slit portions having different transmittances.

  The opening 180c is an opening having a square shape, for example. The light emitted from the first to fourth light emitting units 21 to 24 passes or transmits through the opening 180c, but the amount of light is slightly attenuated by diffusion, diffraction, etc. Etc. have been adjusted.

  For example, when the determination unit 32 determines that the transmittance of light received by the light receiving unit 26 is between 80% and 100%, the light amount is determined to be 1. Therefore, it is assumed that the amount of light that has passed through or transmitted through the opening 180c is 1, and this state is state 1 shown in FIG. In addition, the slit shape and the like may be adjusted so that the transmittance of each slit portion is 50% based on the transmittance of the opening 180c. In the case where there is no shutter unit 18 directly above the light emitting unit, the transmittance is assumed to be 100%.

  For example, as shown in FIG. 5, the first to fourth slit portions 181 to 184 are formed along each side of the opening 180 c. When the operation lever 12 is in the neutral position, a first light emitting unit 21 described later is disposed immediately below the first slit 181, and a second light emitting described below is disposed directly below the second slit 182. The second light emitting unit 23 described later is disposed immediately below the third slit portion 183, and the fourth light emitting unit 24 described later is disposed immediately below the fourth slit portion 184. Has been.

  For example, the first slit portion 181 is formed to face the second slit portion 182 via the opening portion 180c. The third slit portion 183 is formed to face the fourth slit portion 184 via the opening 180c, for example.

  For example, the fifth slit 185 is formed so as to be positioned immediately above the center of the first to fourth light emitting units 21 to 24 when the operation position of the operation lever 12 is “CR” and “P”. (See FIG. 10E described later.)

  For example, when the operation position of the operation lever 12 is “CL” and “P”, the sixth slit portion 186 is formed so as to be positioned immediately above the center of the first to fourth light emitting portions 21 to 24. (See FIG. 10A described later.)

(About the light emitting part)
FIG. 6A is a schematic diagram regarding the arrangement of the light emitting unit and the light receiving unit according to the embodiment of the present invention, and FIGS. 6B to 6E are diagrams regarding the light emission timings of the first to fourth light emitting units. It is. FIG. 7 is a block diagram relating to the turn switch device according to the embodiment of the present invention.

  The light emitting unit group 25 including the first to fourth light emitting units 21 to 24 is disposed on the substrate 20 as shown in FIG. A light receiving unit 26 is arranged on the substrate 20.

  The 1st-4th light emission parts 21-24 consist of light emitting elements, such as a light emitting diode, an organic light emitting diode, a light emitting polymer, a semiconductor laser, for example. As this light emitting element, for example, an element that emits infrared rays or near infrared rays is used. The wavelength is 900 nm as an example, and is determined in consideration of the frequency of vibration generated from the vehicle in order to prevent malfunction.

  The first to fourth light emitting units 21 to 24 are, for example, immediately below the first to fourth slits 181 to 184 when the operation position of the operation lever 12 is “N” and “Hi”. (See FIG. 10 (m) described later.)

  When the operation position of the operation lever 12 is “N” and “Hi”, the first light-emitting portion 21 is disposed immediately below the first slit portion 181, and the second light-emitting portion is directly below the second slit portion 182. 22, the third light emitting unit 23 is disposed immediately below the third slit 183, and the fourth light emitting unit 24 is disposed directly below the fourth slit 184.

  Here, other configurations of the turn switch device 1 include, for example, a light emission control unit 30 that controls the light emission timings of the first to fourth light emitting units 21 to 24, and the vehicle LAN bus 6 as shown in FIG. The control unit 100 controls the output unit 36, the light emission control unit 30, the light receiving unit 26, the determination unit 32, and the output unit 36 that are connected and output an operation position signal of the operation lever 12 as a determination result of the determination unit 32.

  The light emission control part 30 controls the light emission timing of the 1st-4th light emission parts 21-24 as shown below, for example.

For example, the first light emitting unit 21 emits light at the light emission timing shown in FIG. The light emission timing is, for example, a cycle T (for example, 4 ms), the light emission time is t ₂ (for example, 0.4 ms), and the duty ratio is, for example, 10%.

For example, as shown in FIG. 6C, the second light emitting unit 22 emits light after a time t ₁ (for example, 0.6 ms) after the light emission of the first light emitting unit 21 is completed. The light emission period T and the light emission time t ₂ are the same as those of the first light emitting unit 21.

For example, as shown in FIG. 6D, the third light emitting unit 23 emits light after time t ₁ after the light emission of the second light emitting unit 22 is completed. The light emission period T and the light emission time t ₂ are the same as those of the first light emitting unit 21.

For example, as shown in FIG. 6E, the fourth light emitting unit 24 emits light after time t ₁ after the light emission of the third light emitting unit 23 is completed. The light emission period T and the light emission time t ₂ are the same as those of the first light emitting unit 21.

The first light emitting unit 21, for example, light emission of the fourth light emitting unit 24 emits light from the end after a time t _3. In the present embodiment, the time t ₃ from the end of the last light emission to the start of the next light emission is shown in FIGS. 6B to 6E as the same time as the time t ₁ . However, it is not limited to this. The light emission of the first to fourth light emitting units 21 to 24 may be started from any light emitting unit.

(Receiver)
FIG. 8A is a side view of the light guide according to the embodiment of the present invention, FIG. 8B is a top view of the light guide, and FIG. 8C is VIII (c) − in FIG. It is sectional drawing cut | disconnected by the VIII (c) line.

  For example, as illustrated in FIG. 8A, the light receiving unit 26 is disposed on the substrate 20 on which the first to fourth light emitting units 21 to 24 are disposed. Further, for example, since the lower light collecting portion 28B of the light guide 28, which will be described later, is positioned immediately above the light receiving portion 26, the operation of the operation lever 12 in the “Hi” direction causes the light receiving portion 26 to move in the arrow D direction shown in FIG. The displacing shutter portion 18 and the lower light concentrating portion 28B are disposed at a position where they do not contact.

  The light receiving unit 26 includes a light receiving element such as a photodiode, a charge coupled device (CCD), and a complementary metal oxide semiconductor (CMOS).

(About the light guide)
The light guide 28 collects the light emitted from the first to fourth light emitting units 21 to 24 and guides it to the light receiving unit 26. The light guide 28 is stationary with respect to the substrate 20 on which the first to fourth light emitting units 21 to 24 and the light receiving unit 26 are arranged, and the turn switch device 1 includes the light guide 28 and the first to fourth. When the shutter unit 18 is displaced between the light emitting units 21 to 24, the amount of light incident on the light receiving unit 26 changes.

  For example, as shown in FIG. 8A, the light guide 28 has a substantially L-shape when viewed from the side, and as shown in FIG. As shown in FIG. 8 (a), the light receiving portion 26 side end portion is tapered, and a lower condensing portion 28B is schematically configured.

  In addition, the light guide 28 is formed of, for example, a material (for example, an acrylic resin) that transmits light and travels through the interior and totally reflects at the boundary with the exterior.

  28 A of upper condensing parts have the lens 280 formed in the position corresponding to the 1st-4th light emission parts 21-24 on the lower surface 28a, for example. The lens 280 collects the light emitted from the first to fourth light emitting units 21 to 24 and guides the light into the upper light collecting unit 28A.

  The upper light concentrating portion 28A is formed with, for example, first to fourth reflecting portions 281 to 284 that are inclined from the upper surface 28b to the lower surface 28a side. As shown in FIG. 8 (c), the first to fourth reflecting portions 281 to 284 use the optical path of the light condensed by the lens 280 as a connection portion between the upper condensing portion 28A and the lower condensing portion 28B. It changes to the direction of the 5th reflection part 285 formed.

  For example, the light guide 28 may be configured not to include the lens 280 and the first to fourth reflecting portions 281 to 284. In addition, the light guide 28 may have a recess formed on the upper surface 28b instead of the first to fourth reflecting portions 281 to 284, for example. Furthermore, for example, the light guide 28 may be formed with a light shielding film or the like for confining light traveling inside the light guide 28 on a surface other than the exit surface 286 that is an end of the lens 280 and the lower light collecting portion 28B. .

  The first reflecting portion 281 is formed immediately above the first light emitting portion 21, the second reflecting portion 282 is formed immediately above the second light emitting portion 22, and the third reflecting portion 283 is the third reflecting portion. The fourth reflecting portion 284 is formed immediately above the fourth light emitting portion 24.

  The fifth reflecting portion 285 changes the optical path of the light traveling inside the upper light collecting portion 28A, and guides the light toward the emission surface 286 of the lower light collecting portion 28B.

  The lower condensing unit 28B condenses the light whose optical path has been changed by the fifth reflecting unit 285, and the collected light enters the light receiving unit 26 from the emission surface 286 at the end.

(Vehicle system)
For example, as shown in FIG. 7, the vehicle system 5 includes a vehicle LAN bus 6 connected to an electronic device mounted on the vehicle, and the operation lever 12 from the turn switch device 1 via the vehicle LAN bus 6. An input unit 53 for inputting an operation position signal and a vehicle ECU 54 for controlling an electronic device or the like connected to the vehicle LAN bus 6 based on the operation position signal are schematically configured.

  FIG. 9 is a table showing function assignment information according to the embodiment of the present invention. As shown in FIG. 9, the determination unit 32 sets the light amount when the light emitted from the first to fourth light emitting units 21 to 24 is detected by the light receiving unit 26 to “0” and “0.5”. And the function allocation information 320 in which the combination of the light amounts is associated with the operation position of the operation lever 12.

  The determination unit 32 determines the operation position of the operation lever 12 based on the combination of the amounts of light emitted from the first to fourth light emitting units 21 to 24. Since there are only three types of transmittances related to the amount of light used for determination, erroneous determination is prevented, and a maximum of 3 to the fourth power (81 types) position can be determined by combining the three types of transmittances. .

  For example, as shown in FIG. 1, the wiper switch device 7 sets “MIST”, “OFF”, “INT”, “Lo”, and “Hi” as the operation positions of the operation lever with the rotation support shaft 70 as the rotation axis. Have. Although the turn switch device 1 has been described as an example of the combination switch device in the present embodiment, the present invention may be applied to the wiper switch device 7.

  Below, operation | movement of the turn switch apparatus 1 which concerns on this Embodiment is demonstrated, referring each figure.

  Further, the turn switch device 1 can easily detect a large number of operation positions by forming regions having three types of transmittances in the shutter 180 of the shutter unit 18. Further, since the turn switch device 1 determines the operation position based on the combination of the light amounts of light passing through or passing through the regions having three types of transmittances, the turn switch device 1 is compared with the combination switch device that detects the change in the light amount by the number of operation positions. Thus, there are few erroneous determinations of the operation position, and a high-accuracy sensor for detecting the amount of light is not required, resulting in a low cost.
