Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The throttle grip device according to the present embodiment, as shown in FIG. 1, detects the rotation angle of a throttle grip G attached to a handlebar H (handlebar) of a motorcycle, and outputs the detection signal to an ECU or the like mounted on the motorcycle. It is for sending to the electronic control device, and as shown in FIGS. It is composed of a housing member 3 , a magnetic sensor 4 (rotational angle detection means), and a fixing member 6 .

As shown in FIG. 1, the throttle grip G is attached to the tip side of the steering wheel pipe H of the vehicle, and can be rotated by the driver. is capable of reverse rotation b in the opposite direction. As shown in FIGS. 2 and 3, the throttle grip G according to this embodiment is constructed by fixing a gripping member Ga made of soft resin, synthetic rubber, or the like to the outer peripheral surface of a base member Gb made of hard resin, for example. .

The interlocking member 1 is disposed inside the handle pipe H and is composed of a cylindrical member that can rotate in conjunction with the forward rotation a and the reverse rotation b of the throttle grip G. As shown in FIG. An engaged portion 1a integrally formed at one end, a through hole 1b penetrating in the longitudinal direction, an abutting portion 1c integrally formed at one end, and a mounting portion 1d protruding from the other end, and an engaging portion 1e capable of engaging and fixing the other end portion of the second biasing means S2.

The engaged portion 1a is composed of a portion that can be engaged with the base member Gb of the throttle grip G, and the rotational operating force of the throttle grip G is transmitted through the engaged portion 1a to rotate the interlocking member 1 around the axis. It can be rotated. Note that the engaged portion 1a according to the present embodiment is a portion obtained by extending one of the pair of contact portions 1c in the radial direction. It may consist of parts.

The through hole 1b is formed in the axial direction of the interlocking member 1, and has an inner diameter dimension that allows the projecting portion 3b of the accommodating member 3 to be inserted therein. The abutment portion 1c is composed of a pair of projection-shaped portions that protrude in the radial direction from one end portion of the interlocking member 1. As the interlocking member 1 rotates (positive rotation a), the abutted portion 2a of the selection member 2 ( (See FIG. 7). The mounting portion 1d is composed of a pair of projecting shape portions projecting in the axial direction from the other end portion of the interlocking member 1, and as shown in FIG. 10, the magnet M can be mounted thereon.

The housing member 3 houses the substrate 5 and the magnetic sensor 4 formed on the substrate 5. As shown in FIG. It has a projecting portion 3b projecting along the direction and a mounting groove 3c into which the other end of the first biasing means S1 can be inserted and fixed. The accommodation portion 3a can be filled with a waterproof material such as resin after the substrate 5 on which the magnetic sensor 4 is formed is accommodated, and a projecting portion 3b is integrally formed from the center of the accommodation portion 3a. The projecting portion 3b can be inserted into the through hole 1b of the interlocking member 1, and a screw hole 3ba is formed in the tip end surface thereof. The housing member 3 according to this embodiment is fixed inside the handle pipe H with a pair of screws n at the housing portion 3a.

The magnetic sensor 4 (rotational angle detection means) consists of a sensor arranged at a position on the extension line of the rotating shaft of the interlocking member 1, and detects a change in magnetism generated by the magnet M attached to the interlocking member 1. , the rotation angle of the throttle grip G can be detected. Specifically, the magnetic sensor 4 can obtain an output voltage corresponding to a change in the magnetic field of the magnet M (change in magnetic flux density). is composed of a linear Hall IC or the like capable of obtaining an output voltage proportional to the magnetic field (magnetic flux density) of the magnet M. The magnetic sensor 4 according to this embodiment is formed on a substrate 5 (printed substrate) on which a predetermined electric circuit is printed.

Thus, when the interlocking member 1 rotates in the same direction as the throttle grip G rotates forward a, the magnet M attached to the interlocking member 1 also rotates in the same direction by the same angle. As a result, the magnetic field changes depending on the rotation angle, so that an output voltage corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 1 (that is, the rotation angle of the throttle grip G) is detected based on the output voltage. It is possible to The rotation angle of the throttle grip G thus detected is transmitted as an electric signal to an ECU (engine control unit) mounted on the motorcycle, and the vehicle is controlled according to the transmitted rotation angle of the throttle grip G. The engine can be controlled.

On the other hand, when the interlocking member 1 rotates in the same direction as the throttle grip G reversely rotates b, the magnet M attached to the interlocking member 1 also rotates in the same direction by the same angle. As a result, since the magnetic field changes according to the rotation angle, an output voltage corresponding to the rotation angle can be obtained, and the reverse rotation b of the throttle grip G can be detected.

In this way, when the reverse rotation b of the throttle grip G is detected, a predetermined function of the two-wheeled vehicle can be activated or deactivated. This embodiment is applied to a two-wheeled vehicle equipped with a constant vehicle speed holding device (auto-cruise device) that holds the traveling speed constant, and the throttle grip G is rotated in reverse b (forward rotation a in which the throttle is fully opened from the initial position). ), the constant vehicle speed holding control can be stopped (cancelled).

The fixing member 6 is fixed to the tip of the handle pipe H as shown in FIGS. It is configured to have a stopper portion 6a and an insertion hole 6b. The insertion hole 6b is formed at a position that matches the screw hole 3ba formed in the projecting portion 3b of the housing member 3 when the fixing member 6 is fixed to the tip of the handle pipe H, as shown in FIG. Furthermore, the projecting portion 3b can be fixed to the fixing member 6 by inserting the screw f into the insertion hole 6b and screwing it into the screw hole 3ba. The stopper portion 6a is formed of a portion that abuts against the abutted portion 2a formed on the selection member 2 to restrict the rotation of the selection member 2. As shown in FIG. A balancer B (a weight member attached to the tip of the handle pipe H) is attached to the fixed member 6 .

The selection member 2 is an annular member assembled to the interlocking member 1 and arranged inside the handle pipe H. As shown in FIG. and an insertion hole 2d. The abutted portion 2a is composed of a pair of projecting shaped portions projecting from one surface of the selection member 2, and is capable of abutting against the abutting portion 1c of the interlocking member 1 and the stopper portion 6a of the fixing member 6. there is

The mounting groove 2b is shaped like a groove into which one end of the first biasing means S1 is fitted and mounted, and the mounting hole 2c is through which one end of the second biasing means S2 (see FIG. 11) is inserted. It consists of a hole shape to be attached. The insertion hole 2d is a through hole formed in the center of the selection member 2, and has an inner diameter that allows the interlocking member 1 to be inserted therethrough, as shown in FIG. Thus, the selection member 2 is assembled to the interlocking member 1, and has one end of the first urging means S1 attached to one surface and one end of the second urging means S2 attached to the other surface. configured to be

The first biasing means S1 consists of a spring (torsion coil spring) for biasing the interlocking member 1 toward the initial position when the throttle grip G rotates forward a, and one end thereof is formed on the selection member 2. The other end is fixed to a mounting groove 3c formed in the housing member 3 while being fixed to the mounting groove 2b. That is, the first biasing means S1 is attached to the interlocking member 1 so as to be interposed between the selection member 2 and the accommodation member 3 on the outer peripheral surface thereof. Although the first biasing means S1 according to the present embodiment is composed of a torsion coil spring, other biasing means may be used.

The second biasing means S2 consists of a spring (torsion coil spring) for biasing the interlocking member 1 toward the initial position when the throttle grip G reversely rotates b. The other end is fixed to an engaging portion 1e formed in the interlocking member 1 while being fixed to the mounting hole 2c. That is, the second biasing means S2 is attached to the interlocking member 1 so as to be interposed between the interlocking member 1 and the selection member 2 on the one end side thereof. Although the second biasing means S2 according to the present embodiment is composed of a torsion coil spring, other biasing means may be used.

The selection member 2 according to the present embodiment has one end portion of the first urging means S1 and one end portion of the second urging means S2 attached as described above, and when the throttle grip G rotates forward a, the second When the urging force of the first urging means S1 is imparted to the interlocking member 1 without imparting the urging force of the urging means S2 to the interlocking member 1, and the throttle grip G rotates in the reverse direction b, the first urging means S1 is applied. It is configured so that the urging force of the second urging means S2 can be applied to the interlocking member 1 without applying the urging force to the interlocking member 1 .

Specifically, when the throttle grip G is in the initial position (the state before the rotation operation), as shown in FIG. located in When the throttle grip G is rotated forward a, as shown in FIG. 14, the contact portion 1c of the interlocking member 1 contacts and presses the contacted portion 2a, so that the selection member 2 rotates in the same direction. As a result, the biasing force by the first biasing means S1 is applied to the throttle grip G through the interlocking member 1. As shown in FIG. At this time, since the interlocking member 1 and the selection member 2 rotate together, no biasing force is applied by the second biasing means S2.

On the other hand, when the throttle grip G is reversely rotated b, as shown in FIG. Therefore, the selection member 2 does not rotate with the rotation of the interlocking member 1 . One edge of the abutted portion 2a of the selection member 2 is arranged so that when the selection member 2 tries to rotate in the opposite direction b, it abuts against the stopper portion 6a of the fixed member 6 to restrict the rotation. It's becoming As a result, the rotation of the selection member 2 is restricted while the interlocking member 1 rotates, so that the urging force of the second urging means S2 is applied to the throttle grip G via the interlocking member 1. At this time, since the selection member 2 does not rotate, no biasing force is applied by the first biasing means S1.

Here, in this embodiment, the interlocking member 1, the first biasing means S1 and the second biasing means S2 are arranged inside the handle pipe H. As shown in FIG. As a result, the forward rotation (a) and reverse rotation (b) of the throttle grip G can be made possible, and the base end case of the throttle grip G (conventionally, a case accommodating a spring or the like constituting the biasing means) can be made smaller or unnecessary. can do. Further, in this embodiment, in addition to the interlocking member 1, the first biasing means S1 and the second biasing means S2, the housing member 3 housing the magnetic sensor 4 (rotation angle detection means) is also inside the handle pipe H. Since it is fixed, the case on the base end side of the throttle grip G can be further reduced in size or eliminated.

Further, the housing member 3 according to the present embodiment has a housing portion 3a for housing the magnetic sensor 4 (rotation angle detection means), and a projecting portion 3b projecting along the extending direction of the handle pipe H. Since the interlocking member 1 is inserted into the protruding portion 3b so as to be rotatable (rotation accompanying the rotational operation of the throttle grip G), the accommodation member 3 has the function of accommodating the magnetic sensor 4 and the function of attaching the interlocking member 1. In addition, when the interlocking member 1 rotates in conjunction with the throttle grip G, more stable rotation can be performed.

Further, when the throttle grip G rotates in the normal direction a, the urging force of the first urging means S1 is applied to the interlocking member 1 without applying the urging force of the second urging means S2 to the interlocking member 1, so that the throttle grip When G reversely rotates b, the selection member 2 is provided which can apply the biasing force of the second biasing means S2 to the interlocking member 1 without applying the biasing force of the first biasing means S1 to the interlocking member 1. , the first urging means S1 and the second urging means S2 can be selectively operated according to the rotation direction of the throttle grip G.

Although the present embodiment has been described above, the present invention is not limited to this. In addition, the magnetic sensor 4 (rotational angle detecting means) may be arranged in a case attached to the outside of the handle pipe H (base end side of the throttle grip G). Alternatively, the magnetic sensor 4 may be replaced with another sensor capable of detecting the rotation angle of the throttle grip G (such as a sensor that does not use magnetism).

Furthermore, in the present embodiment, when the throttle grip G is rotated in reverse, the constant vehicle speed holding control of the constant vehicle speed holding device (auto-cruise device) is stopped (cancelled). It suffices if a predetermined function of the vehicle is activated or deactivated upon detection of direction rotation. For example, by rotating the throttle grip G in the reverse direction, authentication may be started in an immobilizer system or smart entry system, a starter for starting the engine, or an emergency lighting means such as a hazard may be activated. The applicable vehicle is not limited to a two-wheeled vehicle as in the present embodiment, but may be applied to other vehicles having a handle pipe H (for example, an ATV, a snowmobile, etc.).

It can also be applied to those having different external shapes or those to which other functions are added.
