Description

  The present invention relates to a switch device, and more particularly to a switch device applied to a position detection device for a side stand that detects the position of a side stand that supports a motorcycle such as a motorcycle.

  A motorcycle, such as a motorcycle, is provided with a side stand for preventing the vehicle from toppling during parking and stopping the vehicle. In order to prevent the driver from running the motorcycle without setting the side stand in the retracted position, a position detection device for the side stand is used in many motorcycles.

  In the position detection device for the side stand, the built-in switch device is turned on or off as the side stand of the motorcycle moves between the stand position and the storage position. For this reason, the switch device can operate within the range of the rotation operation, and has a wide ON or OFF region so that the ON or OFF can be continued for each rotation operation on the stand position side and the storage position side. There is a need for a switch device.

  Patent Document 1 discloses a position detection device for a side stand of a motorcycle. FIG. 12 is a perspective view for explaining a conventional side stand position detection apparatus 100. As shown in FIG. 12, in the side stand position detecting device 100, a roller 103 is disposed in a longitudinal direction in a case 104, and a plunger 108 is attached to one end of the roller 103, while the other end is in contact with the case 104. A spring 110 suspended at is attached. A substrate 107 having a fixed contact 107 a is disposed in the case 104, and a movable contact 105 is formed at a position facing the fixed contact 107 a on the roller 103. Thus, the movable contact 105 is connected to and separated from the fixed contact 107 a as the plunger 108 and the roller 103 slide, and the contact / separation signal is transmitted to the ECU mounted on the two-wheeled vehicle through the cord 111. The position (storage position or stand position) of the side stand can be detected by the contact / separation signal. According to this aspect, the movable contact 105 is connected to the fixed contact 107a while the cam member 102 is in contact with a side surface different from the cam surface 102a, and the plunger 108 is in contact with the cam surface 102a. The movable contact 105 is separated from the fixed contact 107a. Therefore, it is possible to have an on region and an off region with a wide rotation angle accompanying rotation.

  For example, if the side stand is in the retracted position, the two-wheeled vehicle can be driven. A part of the vehicle control circuit is cut off. In this case, the off region is a part of the angular range of the cam surface 102a (near the center of the cam surface 102a). When the position of the side stand is moved (rotated) from the off-area range to the storage position side, it becomes an on-area and has an on-area over a wide rotation angle up to a predetermined storage position.

Japanese Patent No. 3976239

  However, the contact portion between the cam member 102 and the plunger 108 contacts and slides so as to maintain the respective states of the on region and the off region over a wide rotation angle corresponding to the rotation amount of the side stand. For this reason, unfavorable stress in the rotation direction is applied to the plunger 108, and the slide operation may become unstable. Furthermore, if the contact portion between the cam surface 102a and the plunger 108 is worn due to long-term use, the positions of the on region and the off region may fluctuate.

  The present invention solves the above-described problems, and provides a switch device that can detect a rotational operation of a member to be detected stably over a long period of time and has a wide on region or off region.

  In order to solve this problem, the switch device of the present invention includes a switch unit that performs contact / separation between contact points by operation, a first rotating member that rotates together with the detected member, and operates the switch unit by rotating. The second rotating member, the interlocking member capable of operating in conjunction with the rotation of the first rotating member and the rotation of the second rotating member and elastically displaceable, and the switch portion by the second rotating member. A rotation stop portion that stops the rotation of the second rotation member in the same direction after the operation is performed, and the interlocking member stops the rotation of the second rotation member in the same direction by the rotation stop portion. Thereafter, the first rotating member is allowed to rotate in the same direction by elastic displacement.

  According to this configuration, the second rotating member rotates in the same direction via the interlocking member as the first rotating member that rotates together with the detected member rotates in one direction, and the second rotating member operates the switch unit. In addition, the first rotating member can continue to rotate in the same direction due to the elastic displacement of the interlocking member by contacting the rotation stopper. Accordingly, the switch can be turned on or off in the middle of the rotation of the detected member, and a wide on region or off region that divides the wide rotation range of the detected member into two can be secured. In addition, the second rotating member that operates the switch unit stops the rotation in the same direction after the operation of the switch unit, and does not slide between the switch unit, so that the second rotating member abuts. The contact part is not worn. Therefore, the rotation operation of the member to be detected can be detected stably over a long period of time and has a wide on region or off region.

  In the switch device of the present invention, the interlocking member is a torsion coil spring disposed between the first rotating member and the second rotating member, and the first rotating member and the second rotating member are respectively The opposing surface has a first locking part and a second locking part, one end of the torsion coil spring is locked to the first locking part, and the other end of the torsion coil spring is the first locking part. The angle formed by the rotation center, the first locking portion, and the second locking portion is equal to or greater than a predetermined angle over a range of angles where the detected member can be rotated. It is characterized by being.

  According to this configuration, the interlocking member is a torsion coil spring disposed between the first rotating member and the second rotating member, and within a predetermined angle range in which the detected member can be rotated by the torsion coil spring. Even after the rotation of the second rotating member is stopped, the first rotating member can be allowed to rotate in the same direction. Further, the angle formed by the rotation center, the first locking portion, and the second locking portion is a predetermined angle or more, and the first locking portion and the second locking portion do not overlap in plan view. The space | interval which the 1st rotation member and the 2nd rotation member oppose can be narrowed.

  In the switch device according to the present invention, the switch section includes a return spring that returns to an initial state, and a spring force of the torsion coil spring is larger than a spring force of the return spring. .

  According to this configuration, the spring force of the torsion coil spring is larger than the spring force of the return spring of the switch unit, and an appropriate elastic displacement is possible. Thereby, when the switch part is pressed by the rotation of the second rotating member, the switch part can be surely pushed out. In addition, since the elastic displacement of the torsion coil spring is used, it operates stably and reliably over a long period of time.

  In the switch device of the present invention, the switch device includes a case member that houses the first rotation member, the second rotation member, the switch unit, the rotation stopper, and the interlock member, and the switch unit is waterproof by the case member. The switch unit and the rotation stopper are fixed to the case member, and the first rotating member and the second rotating member are rotatably supported with respect to the case member. It is characterized by being.

  According to this configuration, the switch portion is housed in the case member so as to be held waterproof and dustproof, the switch portion and the rotation stopper are fixed to the case member, and the first rotation member and the second rotation member are the case. Since it is arranged to be rotatable with respect to the member, the switch portion does not break down. Further, the switch unit and the rotation stopper can be stably fixed, and the first rotating member and the second rotating member can be stably rotated. For this reason, it can be used stably over a long period of time.

  ADVANTAGE OF THE INVENTION According to this invention, the switch apparatus which can detect rotation operation | movement of a to-be-detected member stably over a long period of time, and has a wide ON area | region or an OFF area | region can be provided.

  As shown in FIGS. 1 and 2, the side stand device 1 supports a motorcycle in an upright state at the time of parking, and includes a bracket 2 provided on a vehicle body frame and a side stand rotatably attached to the bracket 2. The bar 3 and the switch device 10 that detects the rotation operation of the side stand bar 3 with respect to the bracket 2 are provided. The side stand bar 3 is in a stand position when the vehicle is stopped and is supported in an upright state. When the vehicle is traveling, the vehicle is stored so as not to interfere with the traveling state at the storage position. In order to prevent the driver from running the motorcycle without setting the side stand in the retracted position, the position of the side stand bar 3 is detected by the switch device 10. That is, the switch device 10 is used as a position detection device for the side stand.

  The bracket 2 includes a plate-like portion 11 and through-pins 12 that pass through the plate-like portion 11 in the thickness direction and are fixed. The plate-like portion 11 pivotally supports the side stand bar 3 so as to be rotatable. The through pin 12 functions as a positioning pin for positioning the switch device 10.

  The side stand bar 3 is attached to the bracket 2 by a pivot bolt 4 and is configured to be rotatable between a stand position grounded to the ground and a storage position substantially horizontal to the ground with the pivot bolt 4 as a rotation axis. Yes. The base end side of the side stand bar 3 is provided with a pair of connecting portions 15 and 16 formed so as to sandwich the plate-like portion 11, and an engagement hole 19 engaged with the switch device 10 is formed through.

  The pivot bolt 4 is fixed by a fixing nut in a state where the bracket 2 is sandwiched between the pair of connecting portions 15 and 16. Thereby, the side stand bar 3 is rotated with respect to the bracket 2 together with the pivot bolt 4. A screw hole 22 into which the fixing bolt 6 is screwed is formed in the head of the pivot bolt 4.

  The fixing bolt 6 is fixed so that the switch device 10 is not dropped by being inserted into the switch device 10 and tightened while being screwed to the pivot bolt 4. The fixing bolt 6 has a circular flange portion 27 at the head, and the switch device 10 is stably pressed by the flange portion 27.

The case member 31 of the switch device 10 is formed with a holding portion 34, and the switch device 10 is positioned by holding the through pin 12 with the holding portion 34.

  Next, a detailed configuration of the switch device 10 will be described with reference to FIGS. FIG. 3 is an exploded perspective view showing the switch device 10 of the present embodiment. FIG. 4 is a plan view showing the switch device 10 of the present embodiment. FIG. 5 is a schematic cross-sectional view of the switch device 10 taken along line VV in FIG. 6A and 6B are schematic cross-sectional views illustrating the switch unit 50. FIG. 6A is a schematic diagram illustrating an initial state, and FIG. 6B is a schematic diagram illustrating an operated state.

  As shown in FIG. 3, the switch device 10 of the present embodiment is a twist in which both ends are fixed by a first rotating member 41, a second rotating member 42, and the first rotating member 41 and the second rotating member 42. The coil spring 43, the switch unit 50, and the rotation stopper 45 are accommodated in the case member 31. The first rotating member 41 accommodated in the case member 31 has an insertion member 47 inserted into the hollow portion thereof, and is sandwiched between the first protection member 48 and the second protection member 49 from both sides of the case member 31.

  The case member 31 is formed of a synthetic resin, and as shown in FIG. 3, a clamping part 34 and a wiring part 35 are provided. The wiring part 35 is a waterproof connector, and is connected so as to transmit a contact / separation signal of the switch part 50 by wiring (not shown) formed in the case member 31. Furthermore, the case member 31 has an accommodating portion, and as shown in FIG. 3, the switch portion 50 and the like are accommodated from the Z2 side. The accommodated components are held waterproof and dustproof by the case member 31, the first protective member 48 on the Z1 side, and the second protective member 49 on the Z2 side.

  The first protective member 48 is made of synthetic resin, and as shown in FIG. 5, the first rotating member 41 is positioned on the case member 31 on the Z1 side.

  The second protective member 49 is made of synthetic resin, and positions the first rotating member 41 on the case member 31 on the Z2 side, as shown in FIG.

  The insertion member 47 is made of synthetic resin, and is inserted into the hollow portion of the first rotation member 41 as shown in FIG. 5 so that the first rotation member 41 can rotate with respect to the fixing bolt 6. The first rotating member 41 and the first rotating member 41 can rotate together.

  The first rotating member 41 is formed in a shape in which a resin material is molded and cylinders having different outer diameters are stacked. An engagement pin 63 to be inserted into the engagement hole 19 provided in the side stand bar 3 is embedded in the first rotation member 41. The engaging pin 63 is made of a metal member, and is integrally formed with the first rotating member 41 made of resin by insert molding. The first rotating member 41 has a first locking portion 41 a that locks one end side of the torsion coil spring 43. The first rotating member 41 is made of metal, and an assembly structure in which the engaging pin 63 and the first locking portion 41a are screwed together, or an integral structure in which the engaging pin 63 and the first locking portion 41a are integrally formed. It may be a structure.

  The second rotating member 42 is formed by molding a resin material into a ring shape that can be slidably contacted with the first rotating member 41. The second rotating member 42 has a second locking portion 42 a that locks the other end side of the torsion coil spring 43. Moreover, the 2nd rotation member 42 has the press part 42b integrally formed so that it might protrude from outer periphery. The pressing portion 42b may have an assembly structure that is screwed to the second rotating member 42. Each of the second rotating member 42, the second locking portion 42a, and the pressing portion 42b may be made of metal.

  The torsion coil spring 43 is an interlocking member that can be operated in conjunction with the rotation of the first rotating member 41 and the rotation of the second rotating member 42 and is elastically displaceable, and has one end engaged with the first locking portion 41a. The one-turn coil is stopped and the other end is locked to the second locking portion 42a. The number of turns of the torsion coil spring 43 is appropriately designed according to the physical properties of the elastic material and the desired amount of displacement, and is not limited to the shape shown in FIG.

  The switch unit 50 is a general-purpose switch product in which a contact / separation operation between contacts is performed by an operation. The switch unit 50 includes a casing 57, an operation unit 51 to be pressed, a fixed contact 53 and a movable contact 54 that can be contacted when the operation unit 51 is pressed, and a movable contact when the pressure is released. A return spring 52 is provided for pulling 54 away from the fixed contact 53 and returning to the initial state. As shown in FIGS. 6A and 6B, the return spring 52 is a spring force that returns to the initial state by configuring the movable contact 54 as a spring member or combining the rubber spring 56. have. As shown in FIG. 6B, the displacement amount from the initial state to the operation state is S1. Further, if a coiled spring is used as the return spring 52 or a combination of the coiled spring and another elastic material, a stronger spring force can be easily obtained.

  In the switch unit 50, the casing 57 is fixed to the case member 31, and the operation unit 51 can be displaced. The fixed contact 53 and the movable contact 54 are each connected to the wiring part 35 (see FIGS. 2 to 4) via wiring (not shown) provided on the case member 31.

  The anti-rotation part 45 prevents the pressing part 42b of the second rotating member 42 from coming into contact with the operating part 51 of the switch part 50 and further pressing the operating part 51 from the state where the operating part 51 is pressed by the displacement amount S1. Therefore, it is fixed to the case member 31. Therefore, since the operation part 51 must be disposed at a position where the operation part 51 can be pressed by the displacement amount S1, the rotation stopper part 45 and the switch part 50 are positioned and fixed to the case member 31 so that the mutual arrangement positions are not displaced. . The rotation stopper 45 may be formed integrally with the case member 31.

  FIG. 7 is a schematic diagram of an initial state for explaining the operation of the switch device 10 of the present embodiment, where (a) is a plan view, (b) is a side view, and (c) is a front view. FIGS. 8A and 8B are schematic views of the rotating state for explaining the operation of the switch device 10, wherein FIG. 8A is a plan view of the state in which the second rotating member 42 has operated the switch unit 50, and FIG. The side view of a state, (c) is a top view of the state which rotated further from the state of (a), (d) is a side view of the state of (c). 7 and 8 show the first rotating member 41 and the second rotating member 42 in a simple disk shape.

  In the initial state of the switch device 10, the pressing portion 42 b of the second rotating member 42 is disposed at a position away from the operation portion 51 as shown in FIG. 7. At this time, the torsion coil spring 43 is in an appropriately elastically displaced state. As shown in FIGS. 7B and 7C, the engaging pin 63 embedded in the first rotating member 41 is located on the Y2 side.

With the rotation of the side stand bar 3 that is the member to be detected, the engagement pin 63 inserted into the engagement hole 19 provided in the side stand bar 3 is driven, and as shown in FIG. The second rotating member 42 rotates. That is, the first rotating member 41 rotates in one direction as shown in FIGS. 8A and 8B, and the position of the first locking portion 41a rotates. In conjunction with the rotation of the first locking portion 41a, the torsion coil spring 43 transmits a driving force so as to rotate the position of the second locking portion 42a in the same direction. If the second rotating member 42 is rotatable, the position of the second locking portion 42a changes corresponding to the position of the first locking portion 41a, and the pressing portion 42b of the second rotating member 42 becomes the switch portion 50. The operation part 51 is contacted. The angle θ formed by the rotation center and the first locking portion 41a and the second locking portion 42a in FIG. 7A, and the rotation center and the first locking portion 41a and the second locking in FIG. 8A. The angle θ ₁ formed by the portion 42a is substantially equal. At this time, by attaching in advance a spring whose spring force of the torsion coil spring 43 is larger than the spring force of the return spring 52 of the switch portion 50, the pressing portion 42b pushes the operating portion 51. As a result, FIG. As shown in b), the movable contact 54 of the switch unit 50 contacts the fixed contact 53.

Since the side stand bar 3 which is a member to be detected further continues to rotate in the same direction, the first rotating member 41 rotates in the same direction as shown in FIGS. The position of the part 41a further rotates. In FIG. 8C, the angle θ ₂ formed by the rotation center and the first locking portion 41a and the second locking portion 42a is smaller than θ ₁ but larger than 0 degrees. At this time, since the pressing portion 42b is in contact with the rotation stop portion 45, the rotation of the second rotating member 42 is restricted so as not to rotate further in the same direction. When the spring force of the torsion coil spring 43 is smaller than the regulation force, the torsion coil spring 43 is elastically displaced, and the first rotating member 41 is interlocked with the side stand bar 3 in the same direction. There is no hindrance. Moreover, since excessive force is not applied to the switch part 50, it can also prevent that the switch part 50 is destroyed. Thereby, the off region and the on region of the switch unit 50 regulate the rotation range of the detected member, the rotation region in which the second rotation member 42 rotates in conjunction with the rotation of the second rotation member 42, and so on. Thus, the first rotation member 41 is divided into a rotation region in which the first rotation member 41 is rotated, and each has a wide rotation angle.

  Hereinafter, the effect by having set it as this embodiment is demonstrated.

  In the switch device 10 of the present embodiment, the first rotating member 41 that rotates together with the detected member rotates in the same direction as the side stand bar 3 that is the detected member rotates, and the torsion coil spring 43 is interlocked. The driving force is transmitted, and the pressing portion 42 b of the second rotating member 42 contacts the operation portion 51 of the switch portion 50 to operate the switch portion 50. At the same time, the pressing portion 42b comes into contact with the rotation stopping portion 45 to restrict the rotation of the second rotating member 42 in the same direction, and the torsion coil spring 43 is elastically displaced. For this reason, the first rotating member 41 can continue to rotate in the same direction together with the detected member due to the elastic displacement of the torsion coil spring 43. According to this configuration, the switch device 10 can be switched on or off in the middle of rotation of the detected member, and a wide on region or off region that divides the wide rotation range of the detected member into two can be secured. . Further, the second rotating member 42 that operates the switch unit 50 stops rotating in the same direction after the operation of the switch unit 50 and does not slide between the switch unit 50. Therefore, the contact part which contacts is not worn. Therefore, the switch device that detects the rotational operation can be stably operated over a long period of time.

  Therefore, the rotation operation of the member to be detected can be detected stably over a long period of time and has a wide on region or off region. The switch unit 50 may have a contact (B contact) structure that is turned off when the operation unit 51 is pushed, instead of a contact point (A contact) structure that is turned on when the operation unit 51 is pushed. Good.

  In the switch device 10 of the present embodiment, the interlocking member is a torsion coil spring 43 disposed between the first rotation member 41 and the second rotation member 42, and one end portion of the torsion coil spring 43 is the first rotation member 41. The other end portion of the torsion coil spring 43 is locked to the second locking portion 42 a of the second rotating member 42. Further, as shown in FIGS. 7 and 8, the angle θ formed between the rotation center and the first locking portion 41a and the second locking portion 42a is larger than 0 degrees over the angular range in which the detected member can be rotated. . As shown in FIGS. 8C and 8D, the first rotating member 41 is rotated even after the rotation of the second rotating member 42 is stopped within a predetermined angle range in which the detected member can rotate. Can be tolerated. At this time, the angle θ formed by the first locking portion 41a and the second locking portion 42a is set to be larger than 0 degree, and does not overlap in plan view as shown in FIGS. The space | interval which the 1st rotation member 41 and the 2nd rotation member 42 oppose can be narrowed. By reducing this interval, a thinner switch device can be obtained.

  In the switch device 10 of the present embodiment, the switch unit 50 has a return spring 52 that returns to the initial state, and the spring force of the torsion coil spring 43 is greater than the spring force of the return spring 52 of the switch unit 50. Appropriate elastic displacement is possible. Thereby, the switch part 50 can be reliably pushed down at the time of the press of the switch part 50 by rotation of the 2nd rotation member 42. FIG. In addition, since the elastic displacement of the torsion coil spring 43 is used, it operates stably and reliably over a long period of time.

  The switch device 10 of the present embodiment includes a case member 31 that houses a first rotating member 41, a second rotating member 42, a switch unit 50, a rotation stopping unit 45, and a torsion coil spring 43 that is an interlocking member. The switch unit 50 is held waterproof and dustproof by the member 31. The switch unit 50 and the rotation stop unit 45 are fixed to the case member 31, and the first rotation member 41 and the second rotation member 42 are rotatably supported with respect to the case member 31. According to this configuration, since water and dust do not adhere to the switch unit 50, it is difficult to break down. In addition, since the switch unit 50 and the rotation stopper unit 45 are stably fixed, and the first rotating member 41 and the second rotating member 42 can be stably rotated, they operate stably. For this reason, it can be used stably over a long period of time.

[Second Embodiment]
Below, the switch apparatus 20 in 2nd Embodiment is demonstrated with reference to FIG.9 and FIG.10. FIG. 9 is a schematic cross-sectional view for explaining the switch device 20 of the second embodiment, and is a schematic cross-sectional view showing a cut surface similar to FIG. FIG. 10 is a schematic diagram of an initial state for explaining the operation of the switch device 20 of the second embodiment, where (a) is a plan view, (b) is a side view, and (c) is a front view. The first embodiment is different from the first embodiment in that two switch portions 50 and two rotation stop portions 45 are provided, and other configurations and materials are the same as those in the first embodiment. The description is omitted.

  As shown in FIGS. 9 and 10, the two switch parts 50 and 70 and the rotation stoppers 45 and 46 are arranged at symmetrical positions, respectively. As shown in FIG. 10A, the operation portion 71 of the switch portion 70 or the operation of the switch portion 50 is operated regardless of whether the pressing portion 42b of the second rotating member 42 is rotated clockwise or counterclockwise. It arrange | positions so that the part 51 may be contact | abutted. The two switch units 50 and 70 are electrically connected so as to form, for example, a parallel circuit.

  In the initial state of the switch device 20, the pressing portion 42 b of the second rotating member 42 is disposed at a position away from the operation portions 51 and 71 as shown in FIG. 10. At this time, the torsion coil spring 43 is in an appropriately elastically displaced state. As shown in FIGS. 10B and 10C, the engaging pin 63 embedded in the first rotating member 41 is located on the Y2 side.

  With the rotation of the side stand bar 3 that is the member to be detected, the engagement pin 63 inserted into the engagement hole 19 provided in the side stand bar 3 is driven, and the first rotation member 41 rotates. That is, the 1st rotation member 41 rotates to one direction (counterclockwise direction in Fig.10 (a)), and the position of the 1st latching | locking part 41a rotates. In conjunction with the rotation of the first locking portion 41a, the torsion coil spring 43 transmits a driving force so as to rotate the position of the second locking portion 42a in the same direction. If the second rotating member 42 is rotatable, the position of the second locking portion 42a changes corresponding to the position of the first locking portion 41a, and the pressing portion 42b of the second rotating member 42 becomes the switch portion 50. The operation part 51 is contacted. At this time, by attaching in advance a spring whose spring force of the torsion coil spring 43 is larger than the spring force of the return spring 52 of the switch unit 50, the pressing unit 42b pushes the operation unit 51. As a result, the switch unit 50 The movable contact 54 contacts the fixed contact 53.

  Since the side stand bar 3 that is the member to be detected further continues to rotate in the same direction, the first rotating member 41 rotates in the same direction, and the position of the first locking portion 41a further rotates. At this time, the rotation of the second rotation member 42 is restricted so that the pressing portion 42b contacts the rotation stopper 45 and does not rotate further in the same direction. When the spring force of the torsion coil spring 43 is smaller than the regulation force, the torsion coil spring 43 is elastically displaced and the first rotating member 41 is prevented from interlocking with the side stand bar 3. There is no. Moreover, since excessive force is not applied to the switch part 50, it can also prevent that the switch part 50 is destroyed. Thereby, the off region and the on region of the switch unit 50 regulate the rotation range of the detected member, the rotation region in which the second rotation member 42 rotates in conjunction with the rotation of the second rotation member 42, and so on. Thus, the first rotation member 41 is divided into a rotation region in which the first rotation member 41 is rotated, and each has a wide rotation angle.

  When the side stand bar 3 that is the member to be detected rotates in the opposite direction (the clockwise direction in FIG. 10A) with respect to the rotation direction in one direction described above, the other switch unit 70 and the rotation stopper Unit 46 similarly functions as described below. The switch unit 70 has the same configuration as the switch unit 50, and details thereof are omitted.

  With the rotation of the side stand bar 3 that is the member to be detected, the engagement pin 63 inserted into the engagement hole 19 provided in the side stand bar 3 is driven, and the first rotation member 41 rotates. That is, the first rotating member 41 rotates in the reverse direction and the position of the first locking portion 41a rotates. In conjunction with the rotation of the first locking portion 41a, the torsion coil spring 43 transmits a driving force so as to rotate the position of the second locking portion 42a in the reverse direction. If the second rotating member 42 is rotatable, the position of the second locking portion 42a changes corresponding to the position of the first locking portion 41a, and the pressing portion 42b of the second rotating member 42 is switched to the switch portion 70. The operation part 71 is contacted. At this time, by attaching in advance a spring whose spring force of the torsion coil spring 43 is larger than the spring force of the return spring of the switch part 70, the pressing part 42b pushes the operation part 71, and as a result, the other switch part 70 movable contacts abut on the fixed contacts.

  Since the side stand bar 3 that is the member to be detected continues to rotate, the first rotating member 41 rotates in that direction, and the position of the first locking portion 41a further rotates in that direction. At this time, the pressing portion 42b comes into contact with the other anti-rotation portion 46 and restricts the rotation of the second rotating member 42 in this direction so as not to rotate any more. When the spring force of the torsion coil spring 43 is smaller than the regulation force, the torsion coil spring 43 is elastically displaced and the first rotating member 41 is prevented from interlocking with the side stand bar 3. There is no. Moreover, since excessive force is not applied to the switch part 70, it can also prevent that the switch part 70 is destroyed. Thereby, the off region and the on region of the switch unit 70 regulate the rotation range of the detected member, the rotation region in which the second rotating member 42 rotates in conjunction with the rotation of the second rotating member 42, and so on. Thus, the first rotation member 41 is divided into a rotation region in which the first rotation member 41 is rotated, and each has a wide rotation angle.

  Hereinafter, the effect by having set it as this embodiment is demonstrated.

  In the switch device 20 of the present embodiment, the first rotating member 41 that rotates together with the detected member rotates in the same direction as the side stand bar 3 that is the detected member rotates, and the torsion coil spring 43 is interlocked. The driving force is transmitted, and the pressing portion 42 b of the second rotating member 42 contacts the operation portion 51 of the switch portion 50 or the operation portion 71 of the switch portion 70 to operate the switch portion 50 or the switch portion 70. At the same time, it contacts the rotation stopper 45 or the rotation stopper 46 to restrict the rotation of the second rotation member 42 in the same direction, and the torsion coil spring 43 is elastically displaced. For this reason, the first rotating member 41 can continue to rotate in the same direction together with the detected member due to the elastic displacement of the torsion coil spring 43. According to this configuration, the switch device 20 can be turned on or off in the middle of rotation of the detected member, and a wide on region or off region that divides the wide rotation range of the detected member into two can be secured. . Further, the second rotating member 42 that operates the switch unit 50 or the switch unit 70 stops rotating in the same direction after the switch unit 50 is operated, and slides between the switch units 50. Since there is no such thing, the contact part that comes into contact does not wear. When the rotation operation of the side stand bar 3 that is the member to be detected is in the reverse direction, the switch unit 70 functions in the same manner, so that even if the rotation is reversed depending on the mounting direction, the mounting is easy. . Therefore, in the switch device that detects the rotation operation, even if the rotation is reversed depending on the mounting direction, the switch device can be easily mounted and can be stably operated over a long period of time.

  Therefore, the rotation operation of the member to be detected can be detected stably over a long period of time and has a wide on region or off region. The switch unit 50 may have a contact (B contact) structure that is turned off when the operation unit 51 is pushed, instead of a contact point (A contact) structure that is turned on when the operation unit 51 is pushed. Good. The same applies to the switch unit 70, and the switch unit 50 and the switch unit 70 are preferably the same.

  In the switch device 20 according to the present embodiment, the interlocking member is a torsion coil spring 43 disposed between the first rotation member 41 and the second rotation member 42, and one end portion of the torsion coil spring 43 is the first rotation member 41. The other end portion of the torsion coil spring 43 is locked to the second locking portion 42 a of the second rotating member 42. In addition, the angle θ between the rotation center and the first locking portion 41a and the second locking portion 42a is greater than 0 degrees over the angular range in which the detected member can rotate. The rotation of the first rotation member 41 can be allowed even after the rotation of the second rotation member 42 is stopped within a predetermined angle range in which the detected member can rotate. At this time, the angle θ formed by the first locking portion 41a and the second locking portion 42a is larger than 0 degrees and does not overlap in plan view, so that the first rotating member 41 and the second rotating member 42 are opposed to each other. It is possible to narrow the interval to be performed. By reducing this interval, a thinner switch device can be obtained.

  In the switch device 20 of the present embodiment, the switch unit 50 has a return spring 52 that returns to the initial state, and the spring force of the torsion coil spring 43 is greater than the spring force of the return spring 52 of the switch unit 50. Appropriate elastic displacement is possible. Thereby, the switch part 50 can be reliably pushed down at the time of the press of the switch part 50 by rotation of the 2nd rotation member 42. FIG. The same applies to the switch unit 70. In addition, since the elastic displacement of the torsion coil spring 43 is used, it operates stably and reliably over a long period of time.

  The switch device 20 according to the present embodiment includes a case member 31 that houses a first rotating member 41, a second rotating member 42, switch units 50 and 70, a rotation stopper 45, and a torsion coil spring 43 that is an interlocking member. The switch portions 50 and 70 are held waterproof and dustproof by the case member 31. The switch units 50 and 70 and the rotation stoppers 45 and 46 are fixed to the case member 31, and the first rotation member 41 and the second rotation member 42 are rotatably supported with respect to the case member 31. According to this configuration, water and dust do not adhere to the switch portions 50 and 70, so that it is difficult for the switch to break down. Further, since the switch units 50 and 70 and the rotation stoppers 45 and 46 are stably fixed, and the first rotation member 41 and the second rotation member 42 can be stably rotated, the switch units 50 and 70 and the rotation stoppers 45 and 46 operate stably. For this reason, it can be used stably over a long period of time.

  As described above, the switch device according to the embodiment of the present invention has been specifically described. However, the present invention is not limited to the first embodiment and the second embodiment described above, and various modifications can be made without departing from the spirit of the present invention. It is possible to change and implement. For example, the present invention can be modified as follows, and these embodiments also belong to the technical scope of the present invention.

For example, FIG. 11 shows a modification of the second embodiment. As the outer diameter of the second rotating member 42 is increased, the switch units 50 and 70, the rotation stoppers 45 and 46, and the pressing unit 42b are disposed on the Z1 side of the second rotating member 42. Since the first rotating member 41 and the second rotating member 42 are in sliding contact with the inner wall of the case member 31, the rotation can be further stabilized.

  (2) In the first embodiment and the second embodiment, the second rotating member 42 has a cylindrical shape (disc shape), but may be any shape and material that can realize the above functions. Further, although the torsion coil spring 43 is used as the interlocking member, other elastic members such as a leaf spring may be used as long as the rotation range is small. Further, the position where the pressing portion 42b is disposed with respect to the engaging pin 63 is not limited.

  (3) In the first and second embodiments, the switch unit 50 is a general-purpose switch product. However, the fixed contact 53, the movable contact 54, and the return spring 52 are arranged in accordance with the case member 31. There may be. The same applies to the switch unit 70 of the second embodiment.

  (4) In 1st Embodiment and 2nd Embodiment, it was set as the structure arrange | positioned so that the switch part 50 and the rotation stop part 45 may adjoin, but it does not need to be an arrangement | positioning adjacent. That is, the pressing portion 42b and the rotation stop portion are provided so that the switch portion 50 can be surely pushed down and an excessive force is applied to the switch portion 50 to prevent the switch portion 50 from being destroyed. The rotation stop structure corresponding to 45 may be provided independently. The same applies to the arrangement of the switch unit 70 and the rotation stopper 46 in the second embodiment.

  In particular, the present invention is useful for a side stand switch and a side stand device that detect a rotation position of a side stand bar that supports a motorcycle such as a motorcycle.
