An embodiment in which the switch driving mechanism according to the present invention is applied to a door handle device 3 of a sliding automatic door 2 of an automobile 1 as shown in FIG. 1 will be described.
As shown in FIGS. 2 and 3, the door handle device 3 according to the present embodiment assembles a handle grip 30 to the handle frame 10 via a crank member 20 and a guide member 25 and switches the handle grip 30 to operate. The drive mechanism 40 is assembled.

  As shown in FIG. 4, the handle frame 10 has a bearing portion 11 that supports a handle grip 30 via a crank member 20 at one end portion thereof, and a protrusion for supporting a guide member 25 described later at the other end portion. The opening portion 12 into which the operation protrusion 32 of the portion 26 and the handle grip 30 can be inserted is provided. Further, the handle frame 10 is provided with a pair of bearing portions 13a and 13b (FIG. 5) on the same axial center for rotatably supporting a connecting member 23 described later on the inward surface of the other end portion.

  The crank member 20 rotatably connects one end 21 to a distal end of a rotating arm 31 of the handle grip 30, which will be described later, and rotates the other end 22 to the bearing 11 of the handle frame 10. Supported as possible.

  The connecting member 23 has both end portions 23a and 23b rotatably fitted to the bearing portions 13a and 13b of the handle frame 10, respectively, and the connecting claw 24 is connected to a closure (not shown) of the automatic door 2 via a wire (not shown). 3), the operation feeling of the handle grip 30 is enhanced.

  The guide member 25 has a support protrusion 26 protruding from its inward surface and a guide taper surface 27 provided at one end of the outward surface.

  As shown in FIGS. 4 and 5, the handle grip 30 has a turning arm portion 31 extending from an inward surface on one end side, and a tip end portion of the handle grip 30 is rotatably connected to one end portion 21 of the crank member 20. It is. Further, the handle grip 30 is provided with an operation protrusion 32 protruding from the inward surface on the other end side, and a substantially square fitting hole 33 is provided at the tip thereof.

  As shown in FIGS. 3 and 5, the switch driving mechanism 40 is configured by connecting and integrating a substantially U-shaped retaining member 70 to the main frame 41, thereby connecting the first operating member 60 and the second operating member 66 to two. It is assembled so as to be slidable via a coil spring 65.

  That is, as shown in FIG. 3, the main frame 41 is integrally formed with the frame body 43 on one end side of the mounting substrate 42, and the engaging claw portions 44 are provided on adjacent edges of the upper and lower surfaces of the frame body 43. Each is provided. The mounting substrate 42 has a second switch 50 provided with an operation lever 51 on its upper surface, and a first switch 52 provided with an operation lever 53 on its lower surface.

  Further, the first operating member 60 is slidably assembled into the second operating member 66 via the two coil springs 65, 65, and then the second operating member 66 is slidable into the frame 43. Mating. Further, by engaging the both side arm portions 71, 71 of the substantially U-shaped retaining member 70 with the frame body 43 of the main frame 41, the first and second operating members 60, 66 are retained. For this reason, the 1st operation member 60 and the 2nd operation member 66 are urged | biased so that it may mutually open | separate. Further, the position of the first operating member 60 is regulated by inserting the position regulating projection 72 projecting from the central portion of the retaining member 70 into the position regulating hole 61 of the first operating member 60.

  A first drive rib 62 for driving the operation lever 53 of the first switch 52 is provided on the inward surface of the first operation member 60, while the other end side edge of the second operation member 66 is provided on the inward surface. A second driving rib 67 for driving the operation lever 51 of the second switch 50 is provided. Further, the first operation member 60 is provided with an operation hole 63 that can be engaged with a driving protrusion 82 of a rotation operation piece 80 described later.

  The rotation operation piece 80 has a drive projection 82 and a fitting tongue 83 projecting radially about a rotation shaft hole 81 and is rotatably supported at the tip of the support projection 26 of the guide member 25. The The driving protrusion 82 engages with the operation hole 63 of the first operation member 60, while the fitting tongue piece 83 engages with the fitting hole 33 of the operation protrusion 32 provided on the handle grip 30. To do.

  The switch drive mechanism 40 is normally assembled to the other end side of the handle frame 10 via the engaging claw 44 of the main frame 41 in an assembled state.

Next, the operation method of the door handle apparatus 3 comprised with the above-mentioned structural member is demonstrated.
As shown in FIGS. 6 and 7, the handle grip 30 is in a stationary state, and both the first switch 52 and the second switch 50 are in an off state. At this time, as shown in FIG. 7B, since the driving protrusion 82 of the rotation operation piece 80 is engaged with the operation hole 63 of the first operation member 60, the rotation operation piece 80 has a spring force of the coil spring 65. Is biased clockwise.

  When the automatic door 2 is slid and opened, when the handle grip 30 is raised as shown in FIGS. 8 and 9, the handle grip 30 rotates with the one end 21 of the crank member 20 as a fulcrum. Caused by movement (FIG. 9). For this reason, since the fitting tongue piece 83 of the turning operation piece 80 fitted into the fitting hole 33 of the operation protrusion 32 is caused, the turning operation piece 80 rotates around the turning shaft hole 81. . As a result, the driving protrusion 82 pulls the first operating member 60 toward one end against the spring force of the coil spring 65, and the first driving rib 62 pushes down the operating lever 53 of the first switch 52 (FIG. 9B). Then, the first switch 52 is turned on, a drive motor (not shown) is started to slide the automatic door 2, and after the automatic door 2 slides to a predetermined position, the drive motor stops.

  On the other hand, when the automatic door 2 is closed, as shown in FIGS. 10 and 11, when the guide taper surface 34 of the handle grip 30 is slid along the taper surface 27 of the guide member 25, FIG. As shown, the crank member 20 is caused to turn around the other end portion 22 as a fulcrum, and the turning arm portion 31 of the handle grip 30 turns around the one end portion 21 as a fulcrum. At the same time, the rotation operation piece 80 passes through the fitting hole 33 of the handle grip 30, and the operation projection 32 presses the end surface on the one end side of the second operation member 66. At this time, the retaining member 70 restricts the sliding movement of the first operating member 60. As a result, only the second operating member 66 slides against the spring force of the coil spring 65, the second driving rib 67 pushes down the operating lever 51 of the second switch 50, and the second switch 50 is turned on (FIG. 10B). Then, the drive motor starts and slides so as to close the automatic door 2, and after the automatic door 2 is closed, the drive motor stops.

  In this embodiment, even when the door handle is being opened, if the door handle is closed, the second switch is turned on after the first switch is turned off, and the automatic door can be closed at an intermediate position. Since the automatic door can be opened by opening the door handle even during closing, there is an advantage that a user-friendly switch can be obtained.

  Of course, the switch drive mechanism according to the present invention is not limited to a sliding automatic door for an automobile, and may be applied to, for example, opening and closing a large automatic door such as a warehouse.
