FIG. 1 is a perspective view of an essential part of a vehicle equipped with a vehicle sunroof device, and a roof panel 2 of the vehicle 1 is formed with a rectangular roof opening 2a. A transparent roof glass 3 is disposed in the rectangular roof opening 2a. The roof glass 3 is provided so as to be capable of reciprocating sliding movement (sliding opening / closing operation) in the front-rear direction.

  A sunshade 4 made of a light-shielding synthetic resin plate is disposed below the roof glass 3 (inside the vehicle), which is the rectangular roof opening 2a. Similar to the roof glass 3, the sunshade 4 is provided so as to be reciprocally slidable in the front-rear direction.

  Then, when the roof glass 3 and the sunshade 4 are slid rearward to open the roof opening 2a together, outside air and outside light can be introduced into the vehicle. Further, when the roof glass 3 is slid forward and closed with respect to the roof opening 2a, and the sunshade 4 is slid backward and opened with respect to the roof opening 2a, the outside air is blocked. External light can be introduced into the vehicle. Furthermore, when the roof glass 3 and the sunshade 4 are slid forward and closed with respect to the roof opening 2a, the introduction of outside air and outside light into the vehicle can be blocked.

  As shown in FIG. 1, a motor M is disposed at the front end of the roof opening 2a and between the roof panel 2 and the indoor ceiling panel (not shown). The motor M is a drive source that reciprocally slides (opens and closes) the roof glass 3 in the front-rear direction and also reciprocates the sunshade 4 in the front-rear direction.

That is, the roof glass 3 and the sunshade 4 are individually reciprocated in the front-rear direction by one motor M.
Next, the drive mechanism of the roof glass 3 and the sunshade 4 will be described.

  As shown in FIG. 2, in the motor M, the output shaft S protruding from the motor case 5 is protruded into the case housing 7 of the speed reduction / clutch portion 6 provided along with the motor case 5. The output shaft S is drivingly connected to a worm shaft 8 that is rotatably supported in the case housing 7.

  The front wall 7a of the case housing 7 is rotatably provided with a first pinion G1 that opens and closes the sunshade 4 via a driving force transmission mechanism (not shown). A second pinion G2 for opening and closing the roof glass 3 is rotatably provided.

  The first pinion G1 rotates forward and backward by forward and reverse rotation of the output shaft S (worm shaft 8) of the motor M via a first pinion drive mechanism A (see FIG. 4) provided in the case housing 7. . Further, the second pinion G2 is rotated in the forward / reverse direction by the forward / reverse rotation of the output shaft S (worm shaft 8) of the motor M via the second pinion drive mechanism B (see FIG. 4) provided in the case housing 7. Rotate.

  Further, a switching control mechanism C (see FIG. 3) is provided in the case housing 7. The switching control mechanism C controls the first and second pinion drive mechanisms A and B to rotate both or one of the first and second pinions G1 and G2 forward and backward.

(Switching control mechanism C)
First, the switching control mechanism C will be described.
(Wheel body 11 for switching)
As shown in FIG. 3, the switching control mechanism C includes a switching worm wheel 10 that meshes with the worm shaft 8 shown in FIG. As shown in FIG. 3, the switching worm wheel 10 has a switching output shaft 13 inserted through a shaft hole 12 formed in the center of the switching wheel body 11, and rotates with respect to the switching output shaft 13. Supported as possible. The switching output shaft 13 has a lower end connected to the rear wall 7b of the case housing 7 so as to be rotatable and non-movable in the axial direction, and an upper end thereof rotatably connected to the front wall 7a of the case housing 7 in the axial direction. It is linked immovably.

  The switching wheel main body 11 has a flange 11a formed on the upper outer peripheral portion, and gear teeth that mesh with the worm shaft 8 are formed on the outer peripheral surface excluding the flange 11a. Therefore, the switching wheel body 11 rotates forward and backward (rotates) in the case housing 7 around the central axis O1 of the switching output shaft 13 by the forward and reverse rotation of the worm shaft 8.

In the present embodiment, the reduction ratio R1 of the rotation speed of the switching wheel body 11 with respect to the rotation speed of the worm shaft 8 (output shaft S) is set in advance.
As shown in FIG. 3, the flange 11 a of the switching wheel body 11 is fitted into a fitting recess 7 c that is recessed in the inner surface of the front wall 7 a of the case housing 7.

  On the upper surface in the axial direction of the switching wheel main body 11, a pair of receiving recesses 15 are provided symmetrically in FIG. 5. The housing recess 15 has a flat inner bottom surface. A stopper wall 16 is formed between the housing recesses 15 by forming a left-right symmetric housing recess 15 on the axial upper surface of the switching wheel body 11.

  As shown in FIG. 5, the accommodating recess 15 has an inner surface facing each other extending in a direction orthogonal to the stopper wall 16 as a guide surface 15a, and the guide surface 15a is formed by planes parallel to each other. In addition, the housing recess 15 has an inner surface facing the stopper wall 16 as a circular arc surface 15b, and the central axis of the central radius of the circular arc surface 15b coincides with the central axis O1.

  Further, as shown in FIG. 5, the shaft hole 12 through which the switching output shaft 13 formed in the central portion penetrates is formed on the upper surface in the axial direction of the switching wheel body 11 to form a large-diameter hole 17. Has been. The large-diameter hole 17 is rotatable on the outer peripheral surface of the output shaft 13 for switching, and the first engaging piece 13a formed to protrude radially outward at positions facing each other across the central axis O1 (rotation) Possible).

  By forming the large-diameter hole 17, the stopper wall 16 is divided with the large-diameter hole 17 interposed therebetween, and a part of the inner bottom surface of the housing recess 15 is expanded as the large-diameter hole 17. As a result, a pair of receiving recesses 15 symmetrically form a pin introduction port 18 communicating with the large-diameter hole 17 between the divided stopper walls 16.

(Switching operation plate 20)
As shown in FIG. 5, the switching operation plates 20 are housed in the pair of housing recesses 15, respectively. A first stopper surface 21 that contacts the stopper wall 16 is formed on the radially inner side of the switching operation plate 20. In addition, an arc-shaped second stopper surface 22 is formed on the radially outer side of the switching operation plate 20 in contact with the arc surface 15b of the housing recess 15.

  When the first stopper surface 21 of the switching operation plate 20 comes into contact with the stopper wall 16, the second stopper surface 22 of the switching operation plate 20 is separated from the arc surface 15 b of the housing recess 15. On the other hand, when the second stopper surface 22 of the switching operation plate 20 comes into contact with the circular arc surface 15 b of the receiving recess 15, the first stopper surface 21 of the switching operation plate 20 is separated from the stopper wall 16. .

  Further, on both sides of the switching operation plate 20, a slidable contact surface 23 is formed which is in slidable contact with the guide surface 15 a of the housing recess 15. Accordingly, the switching operation plate 20 is movable in the radial direction along the pair of guide surfaces 15a and rotates integrally with the switching wheel body 11.

  At the center position of the first stopper surface 21 of the switching operation plate 20, an engagement pin 25 is formed so as to protrude radially inward. When the second stopper surface 22 is in a position where it comes into contact with the arcuate surface 15 b of the receiving recess 15, the tip of the engaging pin 25 is positioned so that it does not cover the large-diameter hole 17 on the inner bottom surface of the receiving recess 15. Is formed. That is, the engagement pin 25 does not engage with the first engagement piece 13a formed on the switching output shaft 13 when the engagement pin 25 rotates about the central axis O1.

  Further, when the first stopper surface 21 is in a position where the engaging pin 25 is in contact with the stopper wall 16, the tip of the engaging pin 25 crosses a part of the large-diameter hole 17 from the pin introduction port 18 and the switching output shaft 13. It is formed so that it may contact. That is, the engagement pin 25 engages with the first engagement piece 13 a formed on the switching output shaft 13.

  As shown in FIGS. 3 and 5, a spring accommodating hole 26 is formed along the line connecting the central axis O <b> 1 from the engagement pin 25 in the switching operation plate 20. A locking piece 27 protruding from the inner bottom surface of the receiving recess 15 is inserted into the spring receiving hole 26. The locking piece 27 is formed to protrude so as to contact the radially inner surface of the spring accommodating hole 26 when the first stopper surface 21 of the switching operation plate 20 contacts the stopper wall 16.

  In the spring accommodating hole 26, a first spring spring SP <b> 1 is disposed between the radially inner inner surface of the spring accommodating hole 26 and the locking piece 27. The first spring spring SP1 always applies an elastic force toward the radially inner side with respect to the switching operation plate 20 (engagement pin 25). Therefore, since the switching plate 20 (engagement pin 25) is always pressed against the stopper wall 16 by the first stopper surface 21, the engagement pin 25 is formed on the output shaft 13 for switching. It is in a state of engaging with the joining piece 13a.

  When the switching wheel body 11 rotates (turns), the switching operation plate 20 turns about the central axis O1. At this time, since the engagement pin 25 of the switching operation plate 20 is engaged with the first engagement piece 13a of the switching output shaft 13 by the first spring spring SP1, the switching output shaft 13 is also switched. Along with the wheel body 11, it is rotated.

  A centrifugal force is applied to the switching operation plate 20 by the turning of the switching operation plate 20. The switching operation plate 20 is increased in force to move radially outward against the elastic force of the first spring spring SP1 due to the centrifugal force. As the centrifugal force increases, the switching operation plate 20 moves away from the position where the first stopper surface 21 abuts against the stopper wall 16, and the second stopper surface 22 faces the arcuate surface 15 b of the housing recess 15. Moving. That is, as the centrifugal force increases, the engagement pin 25 of the switching operation plate 20 comes out of the pin introduction port 18 and is disengaged from the first engagement piece 13 a formed on the switching output shaft 13. It is supposed to move.

  Here, as shown in FIG. 5A, the position where the engagement pin 25 of the switching operation plate 20 is engaged with the first engagement piece 13a of the switching output shaft 13 by the first spring spring SP1. Is called an engagement position. Further, as shown in FIG. 5B, a position where the engagement pin 25 of the switching operation plate 20 is disengaged from the first engagement piece 13a of the switching output shaft 13 is a non-engagement position. That's it.

  In the present embodiment, when the rotation speed of the motor M (the output shaft S and the worm shaft 8) rotates to the first rotation speed N1 or more, as shown in FIG. The combination pin 25 is set to be in a non-engagement position. That is, the switching operation is performed by the centrifugal force (first centrifugal force) applied to the switching operation plate 20 when the rotation speed of the motor M rotates at the reduction ratio R1 with respect to the first rotation speed N1. The engagement pin 25 of the plate 20 moves to the non-engagement position against the elastic force of the first spring spring SP1.

(Control plate 30)
As shown in FIGS. 3 and 6, a control plate 30 is fixed to the lower end portion of the switching output shaft 13. As shown in FIG. 6, the control plate 30 is formed so that the base end portion is fixed to the switching output shaft 13, and extends from both sides of the distal end portion of the movable plate portion 30 a in a quadrant shape. First and second control plate portions 31 and 32 are provided.

  As shown in FIG. 6, the control plate 30 is accommodated in a guide recess 7 d that is recessed in the inner surface of the rear wall 7 b of the case housing 7. The guide recess 7d allows the movable plate portion 30a and the first and second control plate portions 31 and 32 to rotate when the base end portion of the movable plate portion 30a rotates about the rotation center. It is recessed in the shape to be. That is, the guide recess 7d is a recess having a space in which the movable plate portion 30a swings around the central axis O1 and a space in which the first and second control plate portions 31, 32 rotate around the central axis O1. .

  The depth of the guide recess 7d is the same as the thickness of the control plate 30 or slightly deeper. Accordingly, the movable plate portion 30a of the control plate 30 is disposed in the guide recess 7d with its base end connected and fixed to the switching output shaft 13, and its upper surface is substantially flush with the inner surface of the rear wall 7b. It becomes.

  As shown in FIG. 8, the first and second control plate portions 31 and 32 of the control plate 30 have the same symmetrical shape, and are based on the base end arm portions 31 a and 32 a and the base end arm portions 31 a and 32 a. The control units 31b and 32b extend. Further, as shown in FIG. 9, the control portions 31b and 32b are formed such that the distal end portion is thinner than the proximal end portion. Then, the tip portion having a thin plate thickness is defined as a thin region Za, and the base end portion is defined as a thick region Zb having a large plate thickness (the same plate thickness as that of the movable plate portion 30a). The thin region Za is formed by cutting out the upper surface side that does not slide in contact with the inner bottom surface of the guide recess 7d of the control portions 31b and 32b.

  Accordingly, the upper surfaces of the thin regions Za of the control units 31b and 32b are not flush with the inner surface of the rear wall 7b but are positioned in the guide recess 7d. On the other hand, the upper surfaces of the thick regions Zb of the control units 31b and 32b are substantially flush with the inner surface of the rear wall 7b.

The upper surface of the thick region Zb and the upper surface of the thin region Za are connected by a gentle inclined surface.
Further, as shown in FIGS. 6 and 7, support shafts 42 of first and second pinion drive mechanisms A and B, which will be described later, are provided on the control portions 31b and 32b of the first and second control plate portions 31 and 32, respectively. Penetrating arc-shaped escape holes 35, 36 are formed. And the control board 30 rotates in the range shown to Fig.7 (a) and FIG.7 (b), when the output shaft 13 for switching rotates forward / reversely (rotation).

  Here, a state in which the control plate 30 is in a position deviated counterclockwise as shown in FIG. 7B is referred to as a left rotation position (second rotation position). On the contrary, the state in which the control plate 30 is in the position biased in the clockwise direction shown in FIG. 7A is referred to as a right rotation position (third rotation position). Further, as shown in FIG. 6, a state where the movable plate portion 30 a of the control plate 30 is at a position orthogonal to the worm shaft 8 is referred to as a center position (first rotation position).

(First pinion drive mechanism A)
As shown in FIG. 4, the first pinion drive mechanism A that drives the sunshade 4 will be described.

  As shown in FIGS. 2 and 4, a drive worm wheel 40 that meshes with the worm shaft 8 and rotates forward and backward is provided. As shown in FIGS. 4 and 10, the drive worm wheel 40 has a drive wheel main body 41 supported rotatably with respect to a double shaft portion including a support shaft 42 and a cylindrical output shaft 43.

  The base end portion of the support shaft 42 is fixed to the rear wall 7 b of the case housing 7 so as not to rotate. Further, the tip end portion of the support shaft 42 rotatably supports the first pinion G1 that is rotatably supported with respect to the front wall 7a of the case housing 7.

  More specifically, the support shaft 42 penetrates through the relief hole 35 of the first control plate 31 disposed in the guide recess 7d formed in the rear wall 7b of the case housing 7 at the base end portion of the support shaft 42. It is fixed to. The support shaft 42 has a diameter smaller than the width of the arc-shaped escape hole 35 and does not restrict the rotation of the first control plate portion 31. Further, the support shaft 42 is fixed to the rear wall 7b so that the escape hole 35 is located closer to the inclined surface of the thick region Zb of the first control plate portion 31 when the control plate 30 is disposed at the center position. Has been. Therefore, the support shaft 42 allows the control plate 30 to rotate to the left rotation position and to rotate to the right rotation position.

(Cylindrical output shaft 43)
As shown in FIG. 4, the support shaft 42 penetrates the inside of the cylindrical output shaft 43 and supports the cylindrical output shaft 43 so as to be rotatable and movable in the axial direction. The lower end surface of the cylindrical output shaft 43 is in contact with the upper surface of the control unit 31 b of the first control plate unit 31. And the lower end part of the cylindrical output shaft 43 is formed in the magnitude | size by which the outer diameter is interposed in the guide recessed part 7d.

  A large-diameter head 44 is formed on the upper portion of the cylindrical output shaft 43, and an annular wall 45 surrounding the support shaft 42 with a certain interval is formed on the flat upper surface of the head 44. By forming the annular wall 45, a second spring is formed in the space formed by the inner peripheral surface of the annular wall 45, the upper surface of the head portion 44 inside the annular wall 45 and the outer peripheral surface of the support shaft 42. A spring SP2 is disposed (see FIG. 10).

  More specifically, the second spring spring SP <b> 2 is disposed between the latching piece 42 a attached to the support shaft 42 and the upper surface of the head 44 inside the annular wall 45. The second spring spring SP2 always applies an elastic force downward to the cylindrical output shaft 43. Therefore, the lower end surface of the cylindrical output shaft 43 always presses the upper surface of the control unit 31 b of the first control plate unit 31.

  The lower end of the second spring spring SP2 and the upper surface of the head 44 inside the annular wall 45, and the lower end surface of the cylindrical output shaft 43 and the upper surface of the control part 31b of the first control plate part 31, respectively, It is slidably contacted.

  Thus, when the lower end surface of the cylindrical output shaft 43 is in contact with the upper surface of the thick region Zb of the control unit 31b, the cylindrical output shaft 43 is disposed at the upper position. On the contrary, when the lower end surface of the cylindrical output shaft 43 is in contact with the upper surface of the thin area Za of the control unit 31b, the cylindrical output shaft 43 is disposed at the lower position.

  Here, the state in which the cylindrical output shaft 43 is at the upper position shown in FIG. On the contrary, the state in which the cylindrical output shaft 43 is in the lower position shown in FIG. 10A is referred to as a lower height position.

  As shown by a two-dot chain line in FIG. 12, two second engaging pieces 46 are formed on the outer periphery of the annular wall 45 formed on the head portion 44 of the cylindrical output shaft 43 so as to extend radially outward. Yes. The two second engagement pieces 46 are formed so as to face each other across the central axis O2.

  When the cylindrical output shaft 43 is in the upper height position, the annular wall 45 including the second engagement piece 46 is disposed at a position to be inserted into the introduction recess 9 formed on the front wall 7a side of the first pinion G1. Is done. On the other hand, when the cylindrical output shaft 43 is in the lower height position, the annular wall 45 including the second engagement piece 46 is disposed at a position where it exits from the introduction recess 9 formed on the front wall 7a side of the first pinion G1. Is done.

  Here, as shown in FIGS. 4 and 10, the introduction recess 9 formed on the front wall 7a side of the first pinion G1 is a recess having a circular cross section, and a support shaft 42 is provided at the center of the inner bottom surface thereof. It penetrates. And it is rotatably supported with respect to the spindle 42 which penetrated the center part of the inner bottom face.

  As shown in FIG. 12, two third engagement pieces 9 a are formed on the inner peripheral surface of the introduction recess 9 so as to extend radially inward at opposing positions. Then, as shown by a two-dot chain line in FIG. 12, when the cylindrical output shaft 43 rotates in a state where the annular wall 45 including the second engagement piece 46 is inserted into the introduction recess 9, the second engagement piece 46 is The first pinion G1 is rotated by rotating around the central axis O2 and engaging with the third engagement piece 9a of the introduction recess 9 in the circumferential direction.

  On the contrary, even if the cylindrical output shaft 43 rotates in a state where the annular wall 45 including the second engagement piece 46 has come out of the introduction recess 9, the second engagement piece 46 and the third engagement piece 9 a do not move. Since it does not engage, the 1st pinion G1 does not rotate.

(Driving wheel body 41)
As shown in FIGS. 4 and 10, the cylindrical output shaft 43 penetrates the drive wheel main body 41 and rotatably supports the drive wheel main body 41, with respect to the rotating drive wheel main body 41. Are connected so as to be movable in the axial direction.

  The drive wheel main body 41 has a flange 41a formed on the outer peripheral portion of the upper portion, and gear teeth that mesh with the worm shaft 8 are formed on the outer peripheral surface excluding the flange 41a. Accordingly, the drive wheel main body 41 rotates forward and backward in the case housing 7 around the central axis O2 of the support shaft 42 by the forward and reverse rotation of the worm shaft 8.

In this embodiment, the reduction ratio R2 of the rotational speed of the drive wheel main body 41 with respect to the rotational speed of the worm shaft 8 (output shaft S) is set in advance.
As shown in FIG. 4 and FIG. 11, a housing recess 41 b having a circular cross section is formed in the center of the upper surface of the driving wheel body 41, and an annular top surface is formed so as to surround the housing recess 41 b. The inner annular wall 47 is formed to extend upward. An annular outer annular wall 48 is formed on the upper surface of the drive wheel main body 41 and on the outer peripheral portion of the flange 41a so as to extend upward.

An annular guide groove 49 having a constant width is formed on the upper surface of the drive wheel main body 41 along the inner side of the outer annular wall 48.
As shown in FIG. 11, a pair of guide walls 50 project from the upper surface of the drive wheel main body 41 so as to face each other with the central axis O2 interposed therebetween. The radially outer surfaces of the pair of guide walls 50 are formed flush with the radially inner side surface of the annular guide groove 49 formed along the inner side of the outer annular wall 48. The mutually opposing surfaces (guide surfaces 51) of the pair of guide walls 50 are formed by planes facing each other in parallel.

  The pair of guide walls 50 are connected to the inner annular wall 47 with the stopper wall 52 sandwiched between them. Accordingly, the pair of guide surfaces 51 facing each other is divided into two by the stopper wall 52.

  A pair of receiving recesses 53 surrounded by the inner annular wall 47, the pair of guide walls 50, and the stopper wall 52 are formed on the upper surface of the drive wheel main body 41. The pair of receiving recesses 53 are opened radially outward (on the side opposite to the stopper wall 52), that is, on the outer annular wall 48 (annular guide groove 49) side toward the annular guide groove 49.

(Drive plate 60)
The driving operation plates 60 are accommodated in the pair of accommodating recesses 53, respectively. A stopper surface 61 that abuts against the inner annular wall 47 and the stopper wall 52 is formed on the radially inner side of the driving operation plate 60. Further, slidable contact surfaces 62 are formed on both sides of the drive operation plate 60 so as to be in slidable contact with the guide surfaces 51 of the pair of divided guide walls 50. Accordingly, the drive operation plate 60 can move in the radial direction along the guide surfaces 51 of the pair of guide walls 50 and rotates integrally with the drive wheel main body 41.

  On the radially outer side of the drive working plate 60, an arcuate surface 63 having a curvature larger than the curvature of the outer peripheral edge of the upper surface of the drive wheel main body 41 is formed. The arc surface 63 is positioned radially inward of the annular guide groove 49 when the stopper surface 61 is in contact with the side surfaces of the inner annular wall 47 and the stopper wall 52, and both end positions of the arc surface 63 are It is farthest from the annular guide groove 49.

  At the center position of the arc surface 63, an engagement pin 64 is formed to project outward in the radial direction. The engaging pin 64 is formed so as to be positioned radially inward of the annular guide groove 49 when the stopper surface 61 is in a position where it abuts against the inner annular wall 47 and the stopper wall 52. When the drive operation plate 60 moves radially outward, the engagement pin 64 contacts the outer annular wall 48 across the annular guide groove 49. In other words, the driving operation plate 60 is movable between the position where the engagement pin 64 contacts the outer annular wall 48 and the position arranged on the radially inner side of the annular guide groove 49, and the driving wheel body. 41 is housed in the housing recess 53 so as to be rotatable integrally with the housing 41.

  A spring accommodating hole 65 is formed along the line connecting the central axis O2 from the engaging pin 64 in the driving operation plate 60. Then, a locking piece 66 protruding from the upper surface of the drive wheel main body 41 is inserted into the spring accommodating hole 65. The locking piece 66 is formed to protrude so as to contact the radially inner surface of the spring accommodating hole 65 when the stopper surface 61 of the driving operation plate 60 contacts the inner annular wall 47 and the stopper wall 52.

  In the spring accommodation hole 65, a third spring spring SP <b> 3 is disposed between the radially inner surface of the spring accommodation hole 65 and the locking piece 66. The third spring spring SP3 always applies an elastic force to the driving operation plate 60 inward in the radial direction. Accordingly, in the driving operation plate 60, the stopper surface 61 elastically presses the inner annular wall 47 and the stopper wall 52 by receiving the elastic force of the third spring spring SP3, and the engagement pin 64 is radially inward of the annular guide groove 49. It is supposed to be located in. When the driving wheel main body 41 rotates, the driving operation plate 60 that presses the inner annular wall 47 and the stopper wall 52 with the third spring spring SP3 turns around the central axis O2.

  By this turning, centrifugal force is applied to the drive working plate 60. The driving action plate 60 increases the force that moves radially outward against the elastic force of the third spring spring SP3 due to the centrifugal force. Then, as the centrifugal force increases, the driving operation plate 60 moves along the guide surfaces 51 of the guide wall 50 to a position away from the position where the stopper surface 61 contacts the inner annular wall 47 and the stopper wall 52. It is supposed to be. That is, as the centrifugal force increases, the engagement pin 64 of the drive operation plate 60 moves in a direction in which it abuts against the outer annular wall 48 across the annular guide groove 49.

  Here, as shown in FIG. 11B, the positions where the engagement pins 64 of the drive working plate 60 are in contact with the outer annular wall 48 across the annular guide groove 49 by the third spring spring SP3 are connected. It is called position. Further, as shown in FIG. 11A, the position where the engagement pin 64 of the drive working plate 60 is removed from the annular guide groove 49 and retracted radially inward is referred to as a non-connection position.

  In the present embodiment, when the rotation speed of the motor M (the output shaft S and the worm shaft 8) rotates at a speed higher than the second rotation speed N2 higher than the first rotation speed N1, it is shown in FIG. As described above, the engagement pin 64 of the drive operation plate 60 is set to be in the connected position. That is, the driving operation is performed by the centrifugal force (second centrifugal force) applied to the driving operation plate 60 when the driving wheel main body 41 rotates at the reduction ratio R2 with respect to the second rotating speed N2. The engagement pin 64 of the plate 60 moves to the coupling position against the elastic force of the third spring spring SP3.

(Follower 70)
As shown in FIGS. 10A and 10B, a driven body 70 is fitted in the housing recess 41b formed in the center of the drive wheel main body 41, and the driven body 70 is fitted in the housing recess 41b. On the other hand, it is fitted so as to be rotatable about the central axis O2 as a rotation center. The driven body 70 has a large-diameter large-diameter concave portion 71 formed on the upper surface in the axial direction, and a small-diameter concave portion 72 formed on the lower surface in the axial direction. A through-hole 73 that penetrates both bottom surfaces is formed at the center of the bottom surface of the large-diameter recess 71 and the center of the bottom surface of the small-diameter recess 72.

  The through hole 73 is penetrated by a cylindrical output shaft 43 that is rotatable with respect to the support shaft 42 and movable in the axial direction. The through hole 73 is connected to the cylindrical output shaft 43 so as not to rotate. Further, the through hole 73 supports the cylindrical output shaft 43 so as to be movable in the axial direction.

That is, the cylindrical output shaft 43 is connected to the driven body 70 so as to rotate integrally with the driven body 70 and to be movable in the axial direction.
As shown in FIG. 10A, when the cylindrical output shaft 43 is in the lower height position, the large-diameter recess 71 formed on the upper surface of the driven body 70 is the lower surface of the head 44 of the cylindrical output shaft 43. It touches the bottom of the. On the contrary, as shown in FIG. 10B, when the cylindrical output shaft 43 is at the upper height position, the large-diameter recess 71 formed on the upper surface of the follower 70 is the lower surface of the head 44 of the cylindrical output shaft 43. Separated from the bottom surface.

  A flange 74 is formed on the outer peripheral surface of the follower 70. Two fourth engagement pieces 75 are formed on the outer peripheral portion of the flange 74 so as to extend downward. The two fourth engagement pieces 75 are formed so as to face each other across the central axis O2. Further, the distal end portions of the two fourth engagement pieces 75 extend from the outer peripheral portion of the flange 74 so as to be interposed in an annular guide groove 49 formed along the inner side of the outer annular wall 48 of the drive wheel main body 41. Is formed.

  Therefore, as shown in FIG. 11B, when the engagement pin 64 of the drive operation plate 60 is disposed at the coupling position, the engagement pin 64 engages with the fourth engagement piece 75 of the flange 74. To do. As a result, the follower 70 is rotated with the rotation of the drive wheel main body 41 when the rotational force of the drive wheel main body 41 is transmitted to rotate the cylindrical output shaft 43. At this time, when the cylindrical output shaft 43 is at the upper height position, that is, when the annular wall 45 of the cylindrical output shaft 43 is inserted into the introduction recess 9 of the first pinion G1, the second engagement piece 46 and the second When the three engagement pieces 9a are engaged, the first pinion G1 rotates.

  Further, as shown in FIG. 11A, when the engagement pin 64 of the driving operation plate 60 is disposed at the non-connection position, the engagement pin 64 is connected to the fourth engagement piece 75 of the flange 74. Disengagement. As a result, the driven body 70 is in a rotation stopped state because the rotational force of the drive wheel main body 41 is not transmitted, and causes the cylindrical output shaft 43 to be in a rotation stopped state.

(Second pinion drive mechanism B)
Next, the second pinion drive mechanism B that drives the roof glass 3 will be described. The first pinion drive mechanism A and the second pinion drive mechanism B have the same configuration. Further, the first pinion drive mechanism A and the second pinion drive mechanism B are provided at symmetrical positions with the switching control mechanism C interposed therebetween. Therefore, for convenience of explanation, the second pinion drive mechanism B will be briefly described with the same names and symbols as those of the components of the first pinion drive mechanism A.

  The lower end surface of the cylindrical output shaft 43 of the second pinion drive mechanism B abuts on the upper surface (control surface) of the control unit 32 b of the second control plate unit 32. When the lower end surface of the cylindrical output shaft 43 is in contact with the upper surface of the thick region Zb of the control unit 32b of the second control plate unit 32, the cylindrical output shaft 43 is disposed at the upper height position. Conversely, when the lower end surface of the cylindrical output shaft 43 is in contact with the upper surface of the thin region Za of the control unit 32b of the second control plate unit 32, the cylindrical output shaft 43 is disposed at the lower height position.

  When the cylindrical output shaft 43 of the second pinion drive mechanism B is in the upper height position and the cylindrical output shaft 43 rotates, the second pinion G2 rotates. On the contrary, even if the cylindrical output shaft 43 rotates with the cylindrical output shaft 43 of the second pinion drive mechanism B in the lower height position, the second pinion G2 does not rotate.

  That is, in the state where the control plate 30 is disposed at the center position by the switching control mechanism C, the cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B are disposed at the upper height position. Accordingly, when both cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B rotate in this state, the first and second pinions G1 and G2 rotate in the same direction. That is, the roof glass 3 and the sunshade 4 can be opened and closed.

  Further, in a state where the control plate 30 is disposed at the left rotation position by the switching control mechanism C, the cylindrical output shaft 43 of the first pinion drive mechanism A is disposed at the upper height position, and the second pinion drive mechanism B The cylindrical output shaft 43 is disposed at the lower height position. Therefore, even if both the cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B rotate in this state, only the first pinion G1 rotates and the second pinion G2 does not rotate. That is, only the sunshade 4 can be opened and closed.

  Further, in a state where the control plate 30 is disposed at the right rotation position by the switching control mechanism C, the cylindrical output shaft 43 of the first pinion drive mechanism A is disposed at the lower height position, and the second pinion drive mechanism B. The cylindrical output shaft 43 is arranged at an upper height position. Therefore, even if both the cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B rotate in this state, only the second pinion G2 rotates and the first pinion G1 does not rotate. That is, only the roof glass 3 can be opened and closed.

(ECU 80)
As shown in FIG. 2, an electronic control unit (ECU) 80 is provided in the case housing 7 of the speed reduction / clutch unit 6.

  The ECU 80 is a control circuit that controls the rotation of the motor M, and includes a microcomputer. The ECU 80 receives operation signals from a first operation switch SW1 for opening / closing the sunshade provided in the driver's seat, a second operation switch SW2 for opening / closing the roof glass, and a third operation switch SW3 for opening / closing the roof glass / sunshade. .

  When the ECU 80 receives an open / close operation signal or a stop operation signal from the first operation switch SW1, the ECU 80 controls the rotation of the motor M in order to open / close the sun shade 4 or stop the open / close operation. In addition, when an open / close operation signal or a stop operation signal is input from the second operation switch SW2, the ECU 80 controls the rotation of the motor M to open / close or stop the roof glass 3. Further, when an open / close operation signal or a stop operation signal is input from the third operation switch SW3, the ECU 80 controls the rotation of the motor M in order to open / close or stop the roof glass 3 and the sunshade 4 simultaneously.

  When the opening operation signal is output from the first operation switch SW1, the ECU 80 determines that the operation is to open the sunshade 4, and first rotates the motor M in the reverse direction. The control plate 30 rotates from the center position toward the left rotation position until the upper surface of the thin area Za of the second control plate portion 32 and the lower end surface of the cylindrical output shaft 43 of the second pinion drive mechanism B are in sliding contact. The ECU 80 controls the rotation of the motor M when the rotational speed of the motor M is less than the first rotational speed N1. That is, the ECU 80 reversely controls the motor M at less than the first rotation speed N1 until the control plate 30 reaches the left rotation position.

  The ECU 80 once stops the motor M when the control plate 30 reaches the left rotation position, and then changes the rotation direction to the normal rotation direction. At this time, the ECU 80 performs the first rotation speed N1 in the forward rotation direction before the sliding contact between the upper surface of the thin area Za of the second control plate portion 32 and the lower end surface of the cylindrical output shaft 43 of the second pinion drive mechanism B is released. The rotational speed is increased so as to be above, and thereafter, the rotational control is performed so as to become the second rotational speed N2 or more.

Conversely, when a closing operation signal is output from the first operation switch SW1, the ECU 80 determines that the operation is to close the sunshade 4 and rotates the motor M in the reverse direction.
That is, the ECU 80 rotates the control plate 30 from the center position toward the left rotation position by rotating the rotation speed of the motor M less than the first rotation speed N1. When the control plate 30 is in the left rotation position and the upper surface of the thin area Za of the second control plate portion 32 and the lower end surface of the cylindrical output shaft 43 of the second pinion drive mechanism B are in sliding contact, the ECU 80 The rotation speed is increased to the first rotation speed N1 or more, and thereafter, the rotation is controlled to be the second rotation speed N2 or more.

When the stop operation signal is output from the first operation switch SW1, the ECU 80 determines that the operation is to stop the opening / closing operation of the sunshade 4, and stops the rotation of the motor M.
At this time, the ECU 80 temporarily stops the motor M, and then rotates the motor M forward at less than the first rotational speed N1 so that the control plate 30 returns from the left rotation position to the center position. Stop when is returned to the center position. That is, when a stop operation signal is output from the opening operation signal from the first operation switch SW1, the ECU 80 rotates the motor M in the normal rotation direction at a speed less than the first rotation speed N1, and the control plate 30 is moved from the left rotation position. Stop when returning to the center position. Similarly, when a stop operation signal is output from the close operation signal from the first operation switch SW1, the ECU 80 rotates the motor M in the normal rotation direction at less than the first rotation speed N1, and the control plate 30 is moved to the left rotation position. Stop when returning to the center position.

When the opening operation signal is output from the second operation switch SW2, the ECU 80 determines that the operation is to open the roof glass 3, and rotates the motor M in the forward direction.
That is, the ECU 80 rotates the control plate 30 from the center position toward the right rotation position by rotating the rotation number of the motor M forward at less than the first rotation number N1. When the control plate 30 is in the right rotation position and the upper surface of the thin area Za of the first control plate portion 31 and the lower end surface of the cylindrical output shaft 43 of the first pinion drive mechanism A are in sliding contact, the ECU 80 The rotation speed is increased to the first rotation speed N1 or more, and thereafter, the rotation is controlled to be the second rotation speed N2 or more.

  When the closing operation signal of the second operation switch SW2 is output, the ECU 80 determines that the operation is to close the roof glass 3, and first rotates the motor M forward. When the control plate 30 is in the right rotation position and the upper surface of the thin area Za of the first control plate portion 31 and the lower end surface of the cylindrical output shaft 43 of the first pinion drive mechanism A are in sliding contact, the ECU 80 Is temporarily stopped, and then the rotation direction is changed to the reverse rotation direction. At this time, the ECU 80 performs the first rotation speed N1 in the reverse rotation direction before the sliding contact between the upper surface of the thin area Za of the first control plate portion 31 and the lower end surface of the cylindrical output shaft 43 of the first pinion drive mechanism A is released. The rotational speed is increased so as to be above, and thereafter, the rotational control is performed so as to become the second rotational speed N2 or more.

When a stop operation signal is output from the second operation switch SW2, the ECU 80 determines that the operation is to stop the opening / closing operation of the roof glass 3, and stops the rotation of the motor M.
At this time, the ECU 80 temporarily stops the motor M and then reversely rotates the motor M at a speed less than the first rotation speed N1 so that the control plate 30 returns from the right rotation position to the center position. Stop when returning to position. That is, when the stop operation signal is output from the opening operation signal from the second operation switch SW2, the ECU 80 rotates the motor M in the reverse rotation direction at a speed less than the first rotation speed N1, and the control plate 30 is moved from the right rotation position. Stop when returning to the center position. Similarly, when a stop operation signal is output from the close operation signal from the second operation switch SW2, the ECU 80 rotates the motor M in the reverse rotation direction at less than the first rotation speed N1, and the control plate 30 is moved to the right rotation position. Stop when returning to the center position.

  When an opening operation signal is output from the third operation switch SW3, the ECU 80 determines that the operation is to open the roof glass 3 and the sunshade 4 at the same time, and rotates the motor M forward. Moreover, the ECU 80 rotates the control plate 30 from the center position toward the right rotation position, and below the upper surface of the thick area Zb of the first control plate portion 31 and the cylindrical output shaft 43 of the first pinion drive mechanism A. Before the sliding contact with the end face is released, the rotation control is performed so that the rotation speed of the motor M reaches the first rotation speed N1.

Then, after the rotational speed of the motor M reaches the first rotational speed N1 in the forward rotation direction, the ECU 80 controls the rotation so that the rotational speed of the motor M is equal to or higher than the second rotational speed N2 in the forward rotational direction.
Conversely, when a closing operation signal is output from the third operation switch SW3, the ECU 80 determines that the operation is to close the roof glass 3 and the sunshade 4 at the same time, and reversely rotates the motor M. Moreover, the ECU 80 rotates the control plate 30 from the center position toward the left rotation position, and below the upper surface of the thick area Zb of the second control plate portion 32 and the cylindrical output shaft 43 of the second pinion drive mechanism B. Before the sliding contact with the end face is released, the rotation control is performed so that the rotation speed of the motor M reaches the first rotation speed N1.

Then, after the rotational speed of the motor M reaches the first rotational speed N1 in the reverse rotational direction, the ECU 80 controls the rotation so that the rotational speed of the motor M is equal to or higher than the second rotational speed N2 in the reverse rotational direction.
When a stop operation signal is output from the third operation switch SW3, the ECU 80 determines that the operation is to stop the opening / closing operation of the roof glass 3 and the sunshade 4, and stops the rotation of the motor M.

  At this time, the ECU 80 temporarily stops the motor M, then rotates the motor M below the first rotational speed N1 so that the control plate 30 returns to the central position, and stops when the control plate 30 returns to the central position. Let That is, when a stop operation signal is output from the open operation signal from the third operation switch SW3, the ECU 80 rotates the motor M in the reverse rotation direction at less than the first rotation speed N1, and the control plate 30 returns to the center position. Stop when. On the contrary, when the stop operation signal is output from the close operation signal from the third operation switch SW3, the ECU 80 rotates the motor M in the forward rotation direction at less than the first rotation speed N1, and the control plate 30 returns to the center position. Stop when you do.

Next, the operation of this embodiment will be described.
Now, the roof glass 3 and the sunshade 4 are in a fully closed state, and the motor M is stopped. In this stop state, the engagement pin 25 of the switching operation plate 20 of the switching control mechanism C is in the engaged state in which the engagement pin 25 is disposed at the engagement position and engages with the first engagement piece 13 a of the switching output shaft 13. Further, the engagement pin 64 of the drive operation plate 60 of the first and second pinion drive mechanisms A and B is disposed at the non-connection position, and the engagement with the fourth engagement piece 75 of the driven body 70 is disengaged. It is in a joint state.

  Further, in this state, the control plate 30 is disposed at the center position, and both the cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B are disposed at the upper height position. As a result, the second engagement piece 46 of each cylindrical output shaft 43 is in an engagement state to engage with the third engagement piece 9a formed in the introduction recess 9 of the first and second pinions G1, G2.

(Sunshade 4 opening operation)
When the first operation switch SW1 is opened to open the sunshade 4, the ECU 80 inputs an opening operation signal from the first operation switch SW1. The ECU 80 determines that the operation is to open the sunshade 4 and controls the rotation of the motor M so that only the first pinion G1 rotates forward.

  First, the ECU 80 controls the rotation of the motor M so that the motor M rotates in the reverse direction at a rotation speed less than the first rotation speed N1. Due to the reverse rotation of the motor M at less than the first rotation speed N1, the control plate 30 rotates from the center position toward the left rotation position.

  At this time, the rotation speed of the motor M is less than the first rotation speed N1, and the engagement pin 25 of the switching operation plate 20 of the switching control mechanism C is arranged at the engagement position, so that the first output shaft 13 for switching is first. It is in an engaged state with the engaging piece 13a. In addition, although both the drive wheel bodies 41 of the first and second pinion drive mechanisms A and B rotate in the reverse direction, the engagement pin 64 of the drive operation plate 60 of the first and second pinion drive mechanisms A and B is not. Since the coupling position remains, the cylindrical output shaft 43 does not rotate.

  When the control plate 30 is rotated toward the left rotation position and the upper surface of the thin area Za of the second control plate portion 32 and the lower end surface of the cylindrical output shaft 43 of the second pinion drive mechanism B are in sliding contact with each other, The ECU 80 rotates the motor M forward. At this time, the ECU 80 performs the first rotation of the rotational speed of the motor M before the upper surface of the thin area Za of the rotating second control plate portion 32 is disengaged from the lower end surface of the cylindrical output shaft 43 of the second pinion drive mechanism B. Increase the number N1.

  In other words, the cylindrical output shaft 43 of the second pinion drive mechanism B is disposed at the lower height position, and the second engagement piece 46 of the cylindrical output shaft 43 is connected to the third engagement piece 9a of the second pinion G2. When in the disengaged state, the ECU 80 controls the motor M to rotate forward so that the rotation speed quickly reaches the first rotation speed N1.

  When the rotation speed of the motor M reaches the first rotation speed N1, the engagement pin 25 of the switching operation plate 20 of the switching control mechanism C is arranged at the non-engagement position, and the first engagement piece of the switching output shaft 13 The switching output shaft 13 stops rotating (turning) and the control plate 30 stops at the left turning position.

The ECU 80 controls the motor M to rotate forward from the first rotational speed N1 to the second rotational speed N2 or more.
When the rotation speed reaches the second rotation speed N2, the engagement pins 64 of the drive operation plates 60 of the first and second pinion drive mechanisms A and B are arranged at the coupling positions, respectively, and the fourth engagement piece of the cylindrical output shaft 43 75, the two cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B rotate forward.

  At this time, since the cylindrical output shaft 43 of the first pinion drive mechanism A is disposed at the upper height position, the rotational force is transmitted to the first pinion G1 to drive the first pinion G1 in the forward rotation. Then, the sunshade 4 moves in the opening direction by the positive rotation of the first pinion G1.

  On the other hand, since the cylindrical output shaft 43 of the second pinion drive mechanism B is disposed at the lower height position, the rotational force is not transmitted to the second pinion G2, and the second pinion G2 remains stopped. is there.

  Then, when the sunshade 4 moves to the desired open position, the first operation switch SW1 is stopped. Then, the ECU 80 stops the motor M and stops the sunshade 4 at a desired position. At this time, the ECU 80 temporarily stops the motor M, then rotates the motor M in the forward rotation direction at a speed less than the first rotation speed N1, returns the control plate 30 from the left rotation position to the center position, and then stops it. .

Thereby, external light can be introduced into the vehicle.
(Opening operation of the roof glass 3)
When the second operation switch SW2 is opened to open the roof glass 3 from the state where the sunshade 4 is opened, the ECU 80 inputs an opening operation signal from the second operation switch SW2. ECU80 judges that it is operation which opens the roof glass 3, and performs rotation control of the motor M in order to rotate only the 2nd pinion G2.

  First, the ECU 80 controls the rotation of the motor M so that the motor M rotates forward at a rotation speed less than the first rotation speed N1. The control plate 30 rotates from the center position toward the right rotation position by the normal rotation of the motor M at the first rotation speed N1 or less.

  At this time, the rotation speed of the motor M is less than the first rotation speed N1, and the engagement pin 25 of the switching operation plate 20 of the switching control mechanism C is arranged at the engagement position, so that the first output shaft 13 for switching is first. It is in an engaged state with the engaging piece 13a. In addition, although both the drive wheel bodies 41 of the first and second pinion drive mechanisms A and B rotate in the forward direction, the engagement pins 64 of the drive operation plates 60 of the first and second pinion drive mechanisms A and B are not engaged. Since the coupling position remains, the cylindrical output shaft 43 does not rotate.

  When the control plate 30 is rotated toward the right rotation position and the upper surface of the thin area Za of the first control plate portion 31 and the lower end surface of the cylindrical output shaft 43 of the first pinion drive mechanism A are in sliding contact, The ECU 80 controls the rotation of the motor M so that the rotation speed of the motor M reaches the first rotation speed N1.

  In other words, the cylindrical output shaft 43 of the first pinion drive mechanism A is disposed at the lower height position, and the second engagement piece 46 of the cylindrical output shaft 43 is connected to the third engagement piece 9a of the first pinion G1. When in the disengaged state, the ECU 80 controls the motor M to rotate forward so as to reach the first rotation speed N1.

  When the rotation speed of the motor M reaches the first rotation speed N1, the engagement pin 25 of the switching operation plate 20 of the switching control mechanism C is arranged at the non-engagement position, and the first engagement piece of the switching output shaft 13 The switching output shaft 13 stops rotating (turning), and the control plate 30 stops at the right turning position.

Subsequently, the ECU 80 controls the motor M to rotate forward from the first rotation speed N1 to the second rotation speed N2 or more.
When the rotation speed reaches the second rotation speed N2, the engagement pins 64 of the drive operation plates 60 of the first and second pinion drive mechanisms A and B are arranged at the connection positions, respectively, and the fourth engagement piece 75 of the driven body 70 is obtained. The two cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B rotate forward.

  At this time, since the cylindrical output shaft 43 of the second pinion drive mechanism B is disposed at the upper height position, the rotational force is transmitted to the second pinion G2 to drive the second pinion G2 in the forward rotation. And the roof glass 3 moves to an opening direction by the normal rotation of the 2nd pinion G2.

  On the other hand, since the cylindrical output shaft 43 of the first pinion drive mechanism A is disposed at the lower height position, the rotational force is not transmitted to the first pinion G1, and the first pinion G1 remains stopped. is there.

  Then, when the roof glass 3 moves to the desired opening position, the second operation switch SW2 is stopped. Then, the ECU 80 stops the motor M and stops the roof glass 3 at a desired position. At this time, the ECU 80 once stops the motor M, then rotates the motor M in the reverse rotation direction at less than the first rotation speed N1, returns the control plate 30 from the right rotation position to the center position, and then stops it. .

Thereby, outside light and outside air can be introduced into the vehicle.
(Roof glass 3 closing operation)
Subsequently, when the second operation switch SW2 is closed to bring the roof glass 3 into the closed state from the above state, the ECU 80 inputs a close operation signal from the second operation switch SW2. The ECU 80 determines that the operation is to close the roof glass 3, and controls the rotation of the motor M so that only the second pinion G2 rotates backward.

  First, the ECU 80 controls the rotation of the motor M so that the motor M rotates forward at a rotation speed less than the first rotation speed N1. The control plate 30 rotates from the center position toward the right rotation position by the normal rotation of the motor M at the first rotation speed N1 or less.

  At this time, the rotation speed of the motor M is less than the first rotation speed N1, and the engagement pin 25 of the switching operation plate 20 of the switching control mechanism C is arranged at the engagement position, so that the first output shaft 13 for switching is first. It is in an engaged state with the engaging piece 13a. In addition, although both the drive wheel bodies 41 of the first and second pinion drive mechanisms A and B rotate in the forward direction, the engagement pins 64 of the drive operation plates 60 of the first and second pinion drive mechanisms A and B are not engaged. Since the coupling position remains, the cylindrical output shaft 43 does not rotate.

  When the control plate 30 is rotated toward the right rotation position and the upper surface of the thin area Za of the first control plate portion 31 and the lower end surface of the cylindrical output shaft 43 of the first pinion drive mechanism A are in sliding contact, The ECU 80 rotates the motor M in the reverse direction. At this time, the ECU 80 performs the first rotation of the rotational speed of the motor M before the upper surface of the thin region Za of the rotating first control plate portion 31 is disengaged from the lower end surface of the cylindrical output shaft 43 of the first pinion drive mechanism A. Increase the number N1.

  In other words, the cylindrical output shaft 43 of the first pinion drive mechanism A is disposed at the lower height position, and the second engagement piece 46 of the cylindrical output shaft 43 is connected to the third engagement piece 9a of the first pinion G1. When in the disengaged state, the ECU 80 controls reverse rotation of the motor M so that the rotational speed quickly reaches the first rotational speed N1.

  When the rotation speed of the motor M reaches the first rotation speed N1, the engagement pin 25 of the switching operation plate 20 of the switching control mechanism C is arranged at the non-engagement position, and the first engagement piece of the switching output shaft 13 The switching output shaft 13 stops rotating (turning), and the control plate 30 stops at the right turning position.

The ECU 80 performs reverse rotation control of the motor M from the first rotation speed N1 to the second rotation speed N2 or more.
When the rotation speed reaches the second rotation speed N2, the engagement pins 64 of the drive operation plates 60 of the first and second pinion drive mechanisms A and B are arranged at the coupling positions, respectively, and the fourth engagement piece of the cylindrical output shaft 43 75, the two cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B rotate in reverse.

  At this time, since the cylindrical output shaft 43 of the second pinion drive mechanism B is disposed at the upper height position, the rotational force is transmitted to the second pinion G2 to drive the second pinion G2 in the reverse rotation. And the roof glass 3 moves to a close direction by reverse rotation of the 2nd pinion G2.

  On the other hand, since the cylindrical output shaft 43 of the first pinion drive mechanism A is disposed at the lower height position, the rotational force is not transmitted to the first pinion G1, and the first pinion G1 remains stopped. is there.

  For example, when the roof glass 3 moves to the fully closed position, the second operation switch SW2 is stopped. Then, the ECU 80 stops the motor M and stops the roof glass 3 at the fully closed position. At this time, the ECU 80 once stops the motor M, then rotates the motor M in the reverse rotation direction at less than the first rotation speed N1, returns the control plate 30 from the right rotation position to the center position, and then stops it. .

As a result, the outside air is blocked and only the outside light is introduced into the vehicle.
(Sunshade 4 closing operation)
Subsequently, when the first operation switch SW1 is closed to close the sunshade 4 from the above state, the ECU 80 inputs a closing operation signal from the first operation switch SW1. The ECU 80 determines that the operation is to close the sunshade 4 and performs rotation control of the motor M to reversely rotate only the first pinion G1.

  First, the ECU 80 controls the rotation of the motor M so that the motor M rotates in the reverse direction at a rotation speed less than the first rotation speed N1. Due to the reverse rotation of the motor M at less than the first rotation speed N1, the control plate 30 rotates from the center position toward the left rotation position.

  At this time, the rotation speed of the motor M is less than the first rotation speed N1, and the engagement pin 25 of the switching operation plate 20 of the switching control mechanism C is arranged at the engagement position, so that the first output shaft 13 for switching is first. It is in an engaged state with the engaging piece 13a. In addition, although both the drive wheel bodies 41 of the first and second pinion drive mechanisms A and B rotate in the reverse direction, the engagement pin 64 of the drive operation plate 60 of the first and second pinion drive mechanisms A and B is not. Since the coupling position remains, the cylindrical output shaft 43 does not rotate.

  When the control plate 30 is rotated toward the left rotation position and the upper surface of the thin area Za of the second control plate portion 32 and the lower end surface of the cylindrical output shaft 43 of the second pinion drive mechanism B are in sliding contact with each other, The ECU 80 controls the rotation of the motor M so that the rotation speed of the motor M reaches the first rotation speed N1.

  In other words, the cylindrical output shaft 43 of the second pinion drive mechanism B is disposed at the lower height position, and the second engagement piece 46 of the cylindrical output shaft 43 is connected to the third engagement piece 9a of the second pinion G2. When in the disengaged state, the ECU 80 controls the motor M to rotate in reverse so as to reach the first rotation speed N1.

  When the rotation speed of the motor M reaches the first rotation speed N1, the engagement pin 25 of the switching operation plate 20 of the switching control mechanism C is arranged at the non-engagement position, and the first engagement piece of the switching output shaft 13 The switching output shaft 13 stops rotating (turning) and the control plate 30 stops at the left turning position.

Subsequently, the ECU 80 performs reverse rotation control of the motor M from the first rotation speed N1 to the second rotation speed N2 or higher.
When the rotation speed reaches the second rotation speed N2, the engagement pins 64 of the drive operation plates 60 of the first and second pinion drive mechanisms A and B are arranged at the connection positions, respectively, and the fourth engagement piece 75 of the driven body 70 is obtained. The two cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B rotate in reverse.

  At this time, since the cylindrical output shaft 43 of the first pinion drive mechanism A is disposed at the upper height position, the rotational force is transmitted to the first pinion G1 to drive the first pinion G1 in the reverse rotation. And the sunshade 4 moves to a close direction by reverse rotation of the 1st pinion G1.

  On the other hand, since the cylindrical output shaft 43 of the second pinion drive mechanism B is disposed at the lower height position, the rotational force is not transmitted to the second pinion G2, and the second pinion G2 remains stopped. is there.

  For example, when the sunshade 4 moves to the fully closed position, the first operation switch SW1 is stopped. Then, the ECU 80 stops the motor M and stops the sunshade 4 at the fully closed position. At this time, the ECU 80 temporarily stops the motor M, then rotates the motor M in the forward rotation direction at a speed less than the first rotation speed N1, returns the control plate 30 from the left rotation position to the center position, and then stops it. .

Thereby, introduction of outside light and outside air into the vehicle can be blocked.
(Opening operation of the roof glass 3 and the sun shade 4)
When the third operation switch SW3 is opened to simultaneously open the roof glass 3 and the sunshade 4, the ECU 80 inputs an opening operation signal from the third operation switch SW3. The ECU 80 determines that the operation is to open the roof glass 3 and the sunshade 4 at the same time, and controls the rotation of the motor M to rotate the first and second pinions G1 and G2 in the forward direction.

  First, the ECU 80 determines that the number of rotations of the motor M is the first before the control plate 30 at the center position is removed from the thickness region Zb of the control unit 31b before the lower end surface of the cylindrical output shaft 43 of the first pinion drive mechanism A is removed. The motor M is controlled to rotate forward so as to rotate forward at a rotational speed N1 or higher. Therefore, the control plate 30 stops rotating only by being slightly deviated from the center position.

  As a result, both the cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B are arranged at the upper height position, and the second engagement piece 46 of each cylindrical output shaft 43 is connected to the first and second pinions G1, G1. The third engagement piece 9a of G2 is engaged.

  From this state, the ECU 80 controls the motor M to rotate forward from the first rotational speed N1 to the second rotational speed N2 or more. When the rotation speed reaches the second rotation speed N2, the engagement pins 64 of the drive operation plates 60 of the first and second pinion drive mechanisms A and B are arranged at the connection positions, respectively, and the fourth engagement piece 75 of the driven body 70 is obtained. The two cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B rotate forward.

  At this time, since both cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B are arranged at the upper height position, the rotational force causes the first and second pinions G1 and G2 to be positive. Drive to rotate. The roof glass 3 and the sunshade 4 are moved in the opening direction by the positive rotation of the first and second pinions G1 and G2.

  Then, when the roof glass 3 and the sunshade 4 are moved to the desired open position, the third operation switch SW3 is stopped. Then, the ECU 80 stops the motor M and stops the roof glass 3 and the sunshade 4 at the fully closed position. At this time, the ECU 80 temporarily stops the motor M, then rotates the motor M in the reverse rotation direction at a speed less than the first rotation speed N1, returns the control plate 30 from the biased position to the center position, and then stops it.

Thereby, outside light and outside air can be simultaneously introduced into the vehicle.
(Roof glass 3 and sunshade 4 closing operation)
When the third operation switch SW3 is closed to simultaneously close the roof glass 3 and the sunshade 4, the ECU 80 inputs a close operation signal from the third operation switch SW3. The ECU 80 determines that the operation is to simultaneously close the roof glass 3 and the sunshade 4, and performs rotation control of the motor M in order to reversely rotate the first and second pinions G1, G2.

  First, the ECU 80 determines that the number of rotations of the motor M is the first before the control plate 30 at the center position moves from the thick region Zb of the control unit 31b to the lower end surface of the cylindrical output shaft 43 of the second pinion drive mechanism B. The motor M is reversely controlled so as to reversely rotate at the rotational speed N1 or more. Therefore, the control plate 30 stops rotating only by being slightly deviated from the center position.

  As a result, both the cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B are arranged at the upper height position, and the second engagement piece 46 of each cylindrical output shaft 43 is connected to the first and second pinions G1, G1. The third engagement piece 9a of G2 is engaged.

  From this state, the ECU 80 performs reverse rotation control of the motor M from the first rotation speed N1 to the second rotation speed N2 or more. When the rotation speed reaches the second rotation speed N2, the engagement pins 64 of the drive operation plates 60 of the first and second pinion drive mechanisms A and B are arranged at the connection positions, respectively, and the fourth engagement piece 75 of the driven body 70 is obtained. The two cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B rotate in reverse.

  At this time, since both cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B are arranged at the upper height position, the rotational force reverses the first and second pinions G1 and G2. Drive to rotate. The roof glass 3 and the sunshade 4 are moved in the closing direction by the reverse rotation of the first and second pinions G1 and G2.

  For example, when the roof glass 3 and the sunshade 4 are moved to the fully closed position, the third operation switch SW3 is stopped. Then, the ECU 80 stops the motor M and stops the roof glass 3 and the sunshade 4 at the fully closed position. At this time, the ECU 80 temporarily stops the motor M, then rotates the motor M in the forward rotation direction at a speed less than the first rotation speed N1, and returns the control plate 30 from the biased position to the central position and then stops it.

Thereby, introduction of outside light and outside air into the vehicle can be blocked simultaneously.
Next, the effect of the said embodiment is described below.
(1) According to the above-described embodiment, the rotational force of the motor M can be transmitted to both or one of the first and second pinions G1 and G2 only by controlling the rotational speed of one motor M. I made it. That is, one motor M is used to open and close both the roof glass 3 and the sunshade 4 or one of them.

Therefore, an inexpensive, small and light vehicle sunroof device can be realized.
(2) In the above embodiment, the rotation position of the control plate 30 fixed to the switching output shaft 13 is controlled, and the cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B are respectively set to the upper height position. Or set to the lower height position. And, by controlling the upper and lower height positions of the cylindrical output shafts 43 of the first and second pinion drive mechanisms A and B, respectively, both the first and second pinions G1 and G2, or The rotational force of the motor M can be transmitted to either one.

Therefore, the driving of the first and second pinions G1, G2 can be switched with a simple configuration.
(3) In the above embodiment, the first pinion drive mechanism A and the second pinion drive mechanism B have the same configuration. Therefore, parts can be shared and assembly is facilitated.

The above embodiment may be modified as follows.
In the above embodiment, the first spring spring SP1 and the third spring spring SP3 may be provided with an auxiliary member that restricts the displacement in the direction perpendicular to the extending and contracting direction.

  For example, as shown in FIGS. 13 to 15, the first spring spring SP1 may be provided with first and second covers 81 and 82 as auxiliary members. Specifically, first, the first cover 81 is formed into a bottomed rectangular tube shape, and a columnar support column 81a (see FIG. 15) is formed at the bottom thereof. In addition, a claw portion 81 b that protrudes outward is formed on the outer side surface on the opening side of the pair of side walls facing the first cover 81. The second cover 82 is formed in a bottomed rectangular tube shape, and a columnar support column 82a (see FIG. 15) is formed on the bottom thereof. The second cover 82 is formed such that its cylindrical portion can fit the cylindrical portion of the first cover 81, and a long hole 82b is formed at a position corresponding to the claw portion 81b of a pair of opposing side walls. Has been. The first cover 81 is fitted in the second cover 82, and the claw portion 81b is accommodated in the long hole 82b, so that the claw portion 81b can move within the long hole 82b. The movement of the second cover 82 is allowed to move in and out, and the second cover 82 is prevented from coming off. The first spring spring SP1 is housed in a compressed state inside the first cover 81 and the second cover 82 while both ends are fitted on the support pillars 81a and 82a.

  Further, a convex portion 82c is formed on a pair of side walls of the second cover 82 in which the elongated hole 82b is not formed, and the convex portion 82c is formed in the spring accommodating hole 26 in the switching operation plate 20. A fitting recess 26a is formed.

  The first and second covers 81 and 82 that accommodate the first spring spring SP1 accommodate the spring so that the convex portion 82c is fitted in the concave portion 26a and the bottom portion of the first cover 81 contacts the locking piece 27. It is received in the hole 26.

  If it does in this way, the displacement of the orthogonal | vertical direction with respect to the direction where the 1st spring spring SP1 is expanded-contracted by the 1st and 2nd covers 81 and 82 is controlled. Thereby, for example, buckling of the first spring spring SP1, which is a compression coil spring, can be prevented. Further, the assembling property can be improved. Specifically, for example, in the embodiment in which the first spring spring SP1 is directly accommodated in the spring accommodating hole 26, the bottom of the fitting recess 7c (see FIG. 3) of the case housing 7 and the flange of the switching wheel main body 11 are used. Design management of the distance to 11a is difficult, and there is a possibility that the first spring spring SP1 will buckle if the distance is large, but this can be prevented. For example, in the above-described embodiment, the first spring spring SP1 is housed in the spring housing hole 26 and the first spring spring before the switching wheel body 11 (switching worm wheel 10) is assembled to the case housing 7. There is a possibility that the SP1 may jump out of the spring accommodating hole 26 while buckling, and the assembling property is poor, but this assembling property can be improved. Further, since the first and second covers 81 and 82 in this example are held by the long holes 82b and the claw portions 81b so as not to be disassembled in the assembled state, the handling becomes easy and the assembling property is further improved. Can be made.

  In addition, the first and second covers 81 and 82 of the other examples (see FIGS. 13 to 15) are simple bottomed rectangular tube-shaped first and second covers 83 and 84 as shown in FIG. Also good. In this example (see FIG. 16), it cannot be held so as not to be disassembled in the assembled state, but the displacement in the direction perpendicular to the direction in which the first spring spring SP1 expands and contracts is restricted while simplifying the configuration. be able to.

  In the other example (see FIGS. 13 to 15), the first spring spring SP1 that is a compression coil spring is used. However, as shown in FIGS. 17 to 19, the first spring spring SP1 is replaced with a leaf spring 85. You may change to In this example, one first spring spring SP1 is changed to a pair of leaf springs 85. The first and second covers 81 and 82 are changed in size from the above-described another example (see FIGS. 13 to 15) to accommodate the pair of leaf springs 85. The components having the same functions as those shown in FIG. 15 are denoted by the same reference numerals, and the description thereof is omitted.

  Further, as shown in FIGS. 20 to 23, the first and second covers 81 and 82 whose sizes have been changed to accommodate one leaf spring 85 of the above-described another example (see FIGS. 17 to 19) are assembled. Two members may be provided for each switching operation plate 20. That is, in this example, two spring accommodating holes 26 are formed in one switching operation plate 20. The two spring accommodating holes 26 are formed at symmetrical positions so as to extend in parallel to a straight line passing through the engagement pin 25 and the central axis O1. Of course, the locking piece 27 is formed at a position corresponding to each spring accommodating hole 26. And the 1st and 2nd covers 81 and 82 which accommodated one leaf | plate spring 85 are accommodated in the spring accommodation hole 26 similarly to the said another example. Even if it does in this way, the effect similar to the said other example can be acquired.

  In the other example (see FIGS. 13 to 15), the first spring spring SP1 which is a compression coil spring is used. However, as shown in FIGS. You may change to 86. Specifically, in this example, as shown in FIG. 26, both ends of the tension coil spring 86 are housed inside the first cover 81 and the second cover 82 while being fixed to the support pillars 81a and 82a. On the other hand, as shown in FIG. 24, the recess 26 a of the spring accommodation hole 26 is formed on the radially outer side (the side far from the central axis O <b> 1) of the spring accommodation hole 26, and the locking piece 27 is formed on the spring accommodation hole 26. In FIG. 6, the inner side in the radial direction is arranged with respect to the recess 26a. The first and second covers 81 and 82 that house the tension coil spring 86 are springs so that the convex portion 82c is fitted in the concave portion 26a and the bottom portion of the first cover 81 is fixed to the locking piece 27. It is accommodated in the accommodation hole 26. Therefore, in this example, the tension coil spring 86 acts to pull the switching operation plate 20 radially inward (to the central axis O1 side), and when centrifugal force is applied as in the above embodiment, FIG. As shown, the tension coil spring 86 is extended so that the switching operation plate 20 (engagement pin 25) moves to the non-engagement position. In this configuration, since the tension coil spring 86 is used, the buckling does not occur originally, but the assembling property can be improved.

Further, in the above-described another example (see FIGS. 13 to 27), another example related to the first spring spring SP1 is used. However, the third spring spring SP3 may be similarly changed.
In the above embodiment, the first pinion G1 is a sunshade driving pinion and the second pinion G2 is a roof glass driving pinion. The reverse setting may be used.

  In the above embodiment, the opening / closing device is embodied as a vehicle sunroof device, but may be applied to other opening / closing devices of the opening / closing body.
