Description

  The present invention relates to a remote control device for an outboard motor, and more particularly to a brake mechanism for an operation lever of the remote control device.

  Generally, a boat equipped with an outboard motor has a remote control device (hereinafter referred to as a remote control) for remotely operating the outboard motor near a cockpit. In a relatively large boat having a cabin, there are cases where a plurality of outboard motors are provided, and there are cases where a plurality of remote controllers are attached to a plurality of locations on the hull. Conventionally, such a remote control has performed a shift change and a throttle operation by connecting a wire connected to the operation lever to the outboard motor and pulling back the wire.

  However, when the outboard motor is mechanically operated via the wire, a large operating force for pulling the wire is required and the operability is poor. Also, the operation was not stable due to changes such as wire drawing over time. For this reason, a remote controller in which a potentiometer is connected to the rotating shaft of the operating lever instead of a wire has been developed (for example, see Patent Document 1).

  In this remote control, the potentiometer is connected to the rotating shaft of the operating lever via a gear, detects the rotational position of the rotating shaft, that is, the operating position of the operating lever, converts it into an electrical signal, and It is output to a control unit (hereinafter simply referred to as ECU). The ECU controls the rotational speed and direction of the screw according to the electrical signal.

  However, the remote control using this type of potentiometer does not require a large force to operate the operation lever compared to the case of using a wire, so the torque when operating the operation lever is relatively weak, When the boat bounces and vibrates, the operating lever can easily move. If the control lever of the remote control is moved during the maneuvering, the throttle will open more than necessary, which is dangerous. For this reason, in this type of remote controller, a braking mechanism for applying a constant braking force to the rotation shaft of the operation lever is provided to prevent the operation lever from easily moving due to an undesired external force.

For example, in the brake mechanism disclosed in Patent Document 1, the contact portion of the pressing mechanism is brought into contact with the outer peripheral surface of the rotation shaft (support shaft) of the operation lever and pressed by a spring, and another pressing mechanism is pressed from the opposite side. A braking force is applied so that the contact portion is pressed by a spring to sandwich the rotating shaft. However, since the braking force required for the operation lever varies depending on the use situation of the ship and the weather, and the user has a preference, it is desirable that the braking force of the operation lever can be easily adjusted.
JP 2006-62480 A (paragraphs [0073] to [0075], FIG. 14)

  An object of the present invention is to provide a braking mechanism that can easily adjust the braking force of an operation lever, and a remote control device including the braking mechanism.

In order to achieve the above object, a braking mechanism of the present invention is a rotating body that is integrally attached to a drive shaft of an operation lever and has a tapered surface that is inclined in the axial direction on a substantially arcuate outer periphery centered on the drive shaft. When, with giving the brake shoes, the braking force the braking surface of the brake shoe and biases along the drive shaft to the operating lever by pressing on the tapered surface having a braking surface that abuts on the tapered surface A biasing member , and an adjusting mechanism that adjusts a braking force of the operation lever by adjusting a biasing force by the biasing member .

The remote control device according to the present invention is a rotating device having an operation lever and a tapered surface that is integrally attached to a drive shaft of the operation lever, and has a substantially arcuate outer periphery centered on the drive shaft and inclined in the axial direction. A body, a bearing portion that rotatably receives the drive shaft of the operation lever, a housing having a substantially circular recess that rotatably receives the rotating body, and an adjacent to the recess so as to interfere with the rotating body is, with giving the brake shoes, the braking force the braking surface of the brake shoe and biases along the drive shaft to the operating lever by pressing on the tapered surface having a braking surface that abuts on the tapered surface and energizing member, and the adjustment mechanism for adjusting the braking force of the operating lever to adjust the biasing force of the biasing member, to output into an electric signal information about the rotational position of the drive shaft Having a converter, a.

  According to the present invention, the brake shoe has a structure for generating a braking force by pressing the braking surface of the brake shoe against the tapered surface inclined in the axial direction of the rotating body integrally attached to the drive shaft of the operation lever. The braking force can also be generated by urging in the direction. For this reason, for example, the brake shoe can be urged in the axial direction by accessing the adjustment mechanism from a direction substantially parallel to the drive shaft of the operation lever, and the braking force of the operation lever can be easily adjusted from the outside.

  Since the operating lever braking mechanism and the remote operating device including the braking mechanism according to the present invention have the above-described configuration and operation, the braking force of the operating lever can be easily adjusted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic diagram of a boat 10 including a remote control device 1 (hereinafter simply referred to as a remote controller 1) and an outboard motor 2 according to an embodiment of the present invention. Here, an example in which one remote controller 1 is connected to one outboard motor 2 is shown, but the number of outboard motors 2 and remote controllers 1 can be arbitrarily changed according to the type of ship.

  An outboard motor 2 is attached to the stern (rear part) of the boat 10, and a remote controller 1 for remotely operating the outboard motor 2 is attached to a cockpit 3 of the deck. The remote controller 1 has an operation lever 4 that is operated by the operator and a potentiometer 5 connected to the drive shaft of the operation lever 4. The potentiometer 5 functions as a converter of the present invention that converts the rotation angle of the drive shaft of the operation lever 4 into an electrical signal and outputs the electrical signal.

  The outboard motor 2 has an electronic control unit 7 (hereinafter simply referred to as ECU 7) connected to the potentiometer 5 of the remote controller 1 via a harness 6. A throttle motor 8 and a shift actuator 9 are connected to the ECU 7. The throttle motor 8 drives a throttle lever (not shown) for controlling the rotational speed of the screw S based on a control signal from the ECU 7. The shift actuator 9 switches the rotation direction of the screw S based on a control signal from the ECU 7.

  That is, when the operation lever 4 of the remote controller 1 is rotated from the illustrated neutral position to the bow side (traveling direction T side), the angle information is output from the potentiometer 5 to the ECU 7, and the ECU 7 controls the shift actuator 9 to control the screw S. Switch the rotation direction to the forward direction. When the operation lever 4 is further rotated to the bow side from this state, the ECU 7 controls the throttle motor 8 based on the angle information from the potentiometer 5 and rotates the screw S at a speed corresponding to the angle of the operation lever 4.

  Conversely, when the operating lever 4 is rotated from the illustrated neutral position to the stern side (reverse direction), that is, in the direction opposite to the arrow T in the figure, the angle information is output from the potentiometer 5 to the ECU 7, and the ECU 7 controls the shift actuator 9. Then, the rotation direction of the screw S is switched to the reverse direction. When the operation lever 4 is further tilted to the stern side from this state, the ECU 7 controls the throttle motor 8 based on the angle information from the potentiometer 5 and rotates the screw S at a speed corresponding to the angle of the operation lever 4.

  FIG. 2 shows an external perspective view of the remote controller 1 described above. The remote controller 1 of the present embodiment includes two operation levers 4 and 4 for a single main body. That is, the remote controller 1 is also equipped with two potentiometers 5 described above so that two outboard motors 2 (not shown) can be operated independently. In other words, the remote controller 1 has two sets of the same configuration that are substantially symmetrical, except that the shapes of the two operation levers 4 are slightly different. Therefore, in the following description, the configuration on one side will be described as a representative, and the same configuration that is bilaterally symmetric may be denoted by the same reference numeral and detailed description thereof may be omitted.

  As shown in the exploded perspective view of FIG. 3, in addition to the two operation levers 4, the remote controller 1 has a metal housing 12 (housing) in which a drive shaft 11 of each operation lever 4 is rotatably attached. Body), a resin bottom cover 13 screwed to the housing 12, and a resin upper covering the housing 12 in cooperation with the bottom cover 13 so that the ends of the two drive shafts 11 are exposed to the outside. A cover 14 is provided.

  A tilt switch 4a is attached to the operation lever 4 on the left side with respect to the traveling direction of the ship (direction of arrow T in the figure). The tilt switch 4a is a switch for tilting the outboard motor 2 so as to change the depth at which the screw S of the outboard motor 2 sinks in water. When the tilt switch 4a is slid away from the drive shaft 11, the depth of the screw S is increased. The depth of the screw S becomes deeper when it is slid in the direction approaching the drive shaft 11.

  For example, as shown in FIG. 6, the housing 12 has a plurality of screw mounting holes 16 for mounting fixing screws 15 for fixing the remote control 1 to the hull. The screw mounting hole 16 is formed on a side surface substantially orthogonal to the bottom surface where the housing 12 is in contact with the hull surface, and has a shape in which the fixing screw 15 is roughly divided into two along the axial center. In other words, when the fixing screw 15 is moved in a direction crossing the axial direction and mounted in the screw mounting hole 16, the fixing screw 15 restricts its rotation by the shape of the screw mounting hole 16 that substantially matches the shape of the fixing screw 15. Is done.

  When the housing 12 (that is, the remote controller 1) is fixed to the hull using the screw mounting hole 16, first, all the fixing screws 15 are attached to the housing 12 in a state where the remote controller 1 is assembled as shown in FIG. Install in the screw mounting hole 16. At this time, the fixing screw 15 can be mounted in the screw mounting hole 16 through a gap between the side surface of the housing 12 and the bottom cover 13.

  Thereafter, the remote controller 1 is attached to the hull by inserting the corresponding fixing screws 15 into attachment holes (not shown) formed in the hull in advance according to the positions of the plurality of fixing screws 15. In this state, the remote control 1 is not completely fixed to the hull, but the rotation of each fixing screw 15 is restricted by the shape of the screw mounting hole 16 and the dropout from the screw mounting hole 16 is prevented by the mounting hole provided in the hull. Has been. That is, even if the hand is released in this state, the fixing screw 15 does not fall off, and the remote control 1 is also temporarily fixed.

  In this state, a nut (not shown) is screwed and tightened to the fixing screw 15 protruding from the back side of the hull through the attachment hole. Also at this time, the problem that the fixing screw 15 is pushed in the axial direction due to the shape of the screw mounting hole 16 can be prevented, and the attaching operation of the nut can be facilitated. Thereby, the remote control 1 is completely fixed to the hull. As described above, by employing the screw mounting hole 16 that matches the shape of the fixing screw 15, the remote controller 1 can be fastened with a nut without being pressed by hand, so that the remote controller 1 can be attached by one person. In particular, such an attachment structure of the remote controller 1 is effective when the entrance for accessing the back side of the hull for tightening the nut and the attachment position of the remote controller 1 are separated.

  FIG. 4 shows a cross-sectional view of the remote controller 1 taken along the center of the drive shaft 11. The drive shaft 11 is rotatably attached to the housing 12 so as to pass through a substantially annular bush 17 (bearing portion) fitted in the hole 12 a of the housing 12. Then, a washer 18 is attached to the drive shaft 11 outside the hole 12a of the housing 12 (that is, the operation lever 4 side), and a C-type retaining ring (not shown) is fixed to the outside, so that the drive shaft 11 falls off in the axial direction. To prevent that.

  With the drive shaft 11 attached to the housing 12 as described above, the rotating body 20 having a larger diameter than the drive shaft 11 formed integrally with the drive shaft 11 is rotatably accommodated in the substantially circular recess 22 inside the housing 12. Be placed. That is, when the drive shaft 11 integrally provided with the rotator 20 is attached to the housing 12, the tip of the drive shaft 11 is inserted into the bush 17 from the inside of the housing 12 and the rotator 20 is accommodated in the recess 22. Thereafter, the washer 18 and the C-type retaining ring are mounted on the drive shaft 11 to prevent the drive shaft 11 (rotating body 20) from falling off.

  A resin lid 19 is disposed at a position where the recess 22 is closed, that is, on the back side of the housing 12. The lid 19 is fixed to the back surface of the housing 12 with screws after the drive shaft 11 is mounted on the housing 12 as described above.

  The potentiometer 5 described above is fixed to the side of the lid 19 that is away from the housing 12 (back side). By attaching the lid 19 having the potentiometer 5 to the housing 12, the rotary shaft 5 a of the potentiometer 5 protruding toward the housing 12 via the lid 19 is connected to the drive shaft 11 via a resin connection member 21. It has come to be. That is, the potentiometer 5 and the drive shaft 11 are arranged coaxially. At this time, the rotation of the drive shaft 11 can be transmitted to the potentiometer 5 by applying, for example, a D-shaped cross section to the rotary shaft of the potentiometer 5.

  In FIG. 5, the figure which looked at the housing 12 of the state before attaching the cover body 19 from the back surface side is shown. According to this, the rotator 20 is not provided on the entire circumference of the drive shaft 11, but is provided only on one half of the drive shaft 11 in the present embodiment, and is formed in a substantially fan shape centering on the drive shaft 11. ing. Further, a tapered surface 20 a inclined in the axial direction is formed on the outer periphery of the rotator 20 that is separated from the drive shaft 11 in a substantially arc shape. In the present embodiment, the tapered surface 20a is inclined in a radial direction away from the drive shaft 11 from the inner side of the housing 12 (that is, the potentiometer 5 side) to the outer side (the back side of the paper).

  The outer periphery of the rotating body 20 having the tapered surface 20a may be an arc centered on the drive shaft 11 when the braking force of the operation lever 4 described later is made uniform at all rotational positions. When it is desired to change the braking force of the lever 4 in accordance with the rotational position, the curvature of the outer periphery can be changed.

  At a position facing the tapered surface 20a of the rotating body 20, a resin brake shoe 24 having a braking surface 24a contacting the tapered surface 20a is disposed. The brake shoe 24 is housed and disposed in a substantially rectangular recess 23 that is continuous with the substantially circular recess 22 of the housing 12 so that the braking surface 24 a contacts the tapered surface 20 a of the rotating body 20.

  The braking surface 24 a of the brake shoe 24 is inclined according to the shape of the tapered surface 20 a of the rotating body 20 and is curved according to the curvature of the outer periphery of the rotating body 20. For this reason, the braking surface 24a of the brake shoe 24 is in contact with the tapered surface 20a of the rotating body 20 over substantially the entire surface so that the braking force can be sufficiently transmitted.

  FIG. 6 shows an overview of the housing 12 with the operating lever 4 attached to the drive shaft 11 as seen from the outside. According to this, an adjustment mechanism 25 for adjusting the braking force of the operating lever by adjusting the pressing force of the braking surface 24a against the tapered surface 20a is provided at a position facing the above-described brake shoe 24 on the outside of the housing 12. It has been.

  As shown in the cross-sectional view of FIG. 4, the adjustment mechanism 25 extends through the housing 12 substantially parallel to the drive shaft 11 and is screwed into the brake shoe 24, and the adjustment screw 26 is tightened. Accordingly, it has a pressing spring 27 for changing the pressing force for expanding and contracting in the direction of the drive shaft 11 and pressing the braking surface 24a against the tapered surface 20a, and a spacer 28 (regulating member) for restricting the expansion and contraction of the pressing spring 27.

  The pressing spring 27 is accommodated and arranged inside (or outside) a substantially cylindrical resin spacer 28, and the adjusting screw 26 is inserted further inside the pressing spring 27. When the adjustment mechanism 25 is attached to the housing 12, the adjustment screw 26 with the spacer 28 and the pressing spring 27 attached is inserted into the screw hole 29 from the outside of the housing 12 and into the recess 23 inside the housing 12. Screwed onto the arranged brake shoe 24. That is, the pressing spring 27 functions to apply tension to prevent the adjustment screw 26 from falling off and to urge the brake shoe 24 toward the bottom of the recess 22.

  In this state, when the adjusting screw 26 of the adjusting mechanism 25 is rotated to adjust the tightening degree, the brake shoe 24 accommodated in the recess 23 is moved in a direction substantially parallel to the drive shaft 11, and the tapered surface of the braking surface 24a. The pressing force for 20a is adjusted. That is, the force for urging the brake shoe 24 in the axial direction by the adjusting mechanism 25 is that the braking surface 24a of the brake shoe 24 and the tapered surface 20a of the rotating body 20 are inclined with respect to the axial direction. This includes a vector component in the direction of pressing against the tapered surface 20a, and the pressing force between the braking surface 24a and the tapered surface 20a can be adjusted by adjusting the adjusting screw 26.

  By the way, the operating lever 4 is attached from the outside of the housing 12 to the drive shaft 11 provided with the braking force adjusting mechanism 25 as described above. When the operation lever 4 is attached to the drive shaft 11, the drive shaft 11 having an unevenness on the outer peripheral surface is fitted into the attachment hole 4 b having the corresponding unevenness of the operation lever 4 and fixed from the outside of the operation lever 4 with a screw 31. In this way, by providing irregularities on the outer peripheral surface of the drive shaft 11 and the mounting hole 4b of the operation lever 4, it is possible to prevent slippage in the rotational direction between them, and to reliably rotate the drive shaft 11 by operating the operation lever 4. be able to.

  The adjusting screw 26 of the adjusting mechanism 25 described above is attached to and detached from the connecting portion of the covers 13 and 14 with the bottom cover 13 and the upper cover 14 attached so as to surround the outside of the housing 12 (the state shown in FIG. 2). Access is made possible by removing the grommet 32 (FIG. 3) attached thereto. That is, according to the present embodiment, the braking force of the operation lever 4 can be adjusted from the outside of the main body of the remote controller 1.

  In particular, according to the present invention, the rotating body 20 provided integrally with the drive shaft 11 for applying the braking force is provided with the tapered surface 20a, and the tapered surface 20a is pressed against the braking surface 24a of the brake shoe 24. The adjusting screw 26 extending substantially parallel to the drive shaft 11 can be accessed from the outside of the housing 12 from the direction parallel to the drive shaft to adjust the tightening degree, and the remote controller 1 is removed for adjusting the braking force. There is no need to remove the cover or the cover, and the braking force of the operation lever 4 can be easily adjusted.

  Returning to FIG. 5, a click stop mechanism 34 is provided on the opposite side of the rotating body 20 across the drive shaft 11. The click stop mechanism 34 functions to lock the operation lever 4 at three positions during its rotation. Specifically, the clip stop mechanism 34 locks the operation lever 4 at a neutral position and at two positions sandwiching the neutral position.

  That is, the clip stop mechanism 34 has an elongated accommodating portion 35 that integrally extends in a direction away from the drive shaft 11 with respect to the rotating body 20, and a detent spring 36 (biasing spring) is accommodated in the accommodating portion 35. The roller 38 (fitting member) is rotatably provided via a resin roller guide 37 at the tip of the detent spring 36 (that is, the end facing the side wall 22a of the recess 22). Three small concave portions 39 (grooves) for receiving the rollers 38 are formed on the side wall 22a of the concave portion 22 in which the clip stop mechanism 34 is accommodated.

  For example, when the operation lever 4 is rotated to the neutral position, the roller 38 of the click stop mechanism 34 is pressed toward the side wall 22a of the concave portion 22 by the detent spring 36 and is fitted into the central concave portion 39. When the operation lever 4 is rotated in one direction from this state, the roller 38 is fitted into the adjacent concave portion 39, and when the operation lever 4 is rotated in the reverse direction, the roller 38 is fitted into the reverse adjacent concave portion 39. The concave portions 39 and 39 for positioning the front and rear of the neutral position respectively define the rotation position of the operation lever 4 that switches the rotation direction of the screw S and starts opening the throttle.

  Next, the waterproof structure of the remote controller 1 will be described with reference to FIGS. 7 and 8 together with FIG. FIG. 7 shows a partially cutaway view of the covers 13 and 14 of the remote control 1, and FIG. 8 shows a perspective view of the inside of the upper cover 14.

  As shown in FIGS. 3 and 7, a rib 41 curved in a shape surrounding the lower side of the drive shaft 11 is integrally provided on the side surface of the housing 12 from which the drive shaft 11 protrudes. The rib 41 is provided so as to protrude integrally from the side wall of the housing 12 toward the inner wall of the bottom cover 13, and water that enters from the gap between the operation lever 4 and the covers 13, 14 flows forward and backward of the remote control 1. To prevent that. Then, the water that flows into the inside of the rib 41 flows out through a hole 13 a formed on the near side of the bottom cover 13.

  On the other hand, as shown in FIG. 3 and FIG. 8, a case 42 is provided on the inner side of the sleeve portion through which the operation lever 4 of the upper cover 14 is inserted to collect water that enters from the gap. The case 42 is integrally attached to the inside of the side wall of the upper cover 14. More specifically, the case 42 includes a portion 43 that contacts the side wall of the housing 12 in a state of surrounding the housing 12, and a seal portion 44 that seals the portion 43 and the inner surface of the upper cover 14. It functions to guide the water that has entered from the inside of the rib 41 on the housing side.

  That is, as shown in FIG. 7, the seal portion 44 of the case 42 of the upper cover 14 slightly overlaps the inside of the rib 41 on the housing 12 side in a state where the housing 12 is surrounded by the covers 13 and 14. For this reason, the water that has entered the cover through the annular gap between the operation lever 4 and the sleeves of the covers 13 and 14 is blocked by the case 42 and the ribs 41, and the holes 13a of the bottom cover 13 are blocked. Will flow out to the outside of the remote control 1.

  As described above, by adopting this waterproof structure, the amount of water entering the cases 13 and 14 of the remote controller 1 can be greatly reduced, and the water that wets the potentiometer 5 along the inner upper surface of the upper cover 14. The amount can be greatly reduced, and stable operation of the potentiometer 5 can be realized.

However, the present invention is not limited to this, and the present invention is applied to a remote controller having one operation lever. May be.

  In the above-described embodiment, the case where the tapered surface 20a of the rotating body 20 formed integrally with the operation lever 4 is inclined in the direction away from the drive shaft 11 from the inside to the outside of the housing 12 has been described. Not only this but the inclination direction of the taper surface 20a can also be made into a reverse direction. In this case, the brake shoe 24 may be urged in the opposite direction along the axial direction in order to press the braking surface 24a of the brake shoe 24 against the tapered surface 20a.
