  However, in the above-mentioned conventional throttle grip device, since the second biasing means comprises a coil spring attached in an arc shape along the rotation direction of the interlocking member, the throttle grip is reversely rotated to form the arc shape. When the coil spring is compressed, a loss (loss of the spring load) is generated in the obtained spring load, and there is a possibility that an extra sliding resistance may be generated.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a throttle grip device capable of efficiently generating urging force by a second urging unit attached to an interlocking member.

  According to a first aspect of the present invention, there is provided a throttle grip capable of a rotation operation by a driver and capable of normal rotation in a predetermined direction from an initial position and reverse rotation in a direction opposite to the predetermined direction; An interlocking member capable of rotating interlockingly with forward rotation and reverse rotation, a case rotatably holding the interlocking member, and biasing the interlocking member toward the initial position when the throttle grip is positively rotated (1) biasing means, second biasing means for biasing the interlocking member toward the initial position when the throttle grip is reversely rotated, and second biasing means when the throttle grip is positively rotated. Biasing means capable of applying the biasing force of the second biasing means to the interlocking member when the throttle grip is reversely rotated without applying the biasing force to the interlocking member; And a rotation angle detection means capable of detecting the rotation angle of the throttle grip by detecting the rotation angle of the member, and the rotation angle of the throttle grip detected by the rotation angle detection means in accordance with the rotation angle during positive rotation A throttle grip device capable of controlling an engine of a vehicle and capable of activating or deactivating a predetermined function of the vehicle when the throttle grip is reversely rotated, wherein the second biasing means is connected to the interlocking member. A plurality of coil springs are linearly accommodated in the formed housing portion, and are formed along the rotation direction of the interlocking member, and are interposed between the interlocking member and the biasing force application means to perform biasing force. It is characterized in that it can be applied.

  According to a second aspect of the present invention, in the throttle grip device according to the first aspect, the second biasing means is constituted by six of the coil springs disposed in the rotational direction of the interlocking member. It is characterized by

  According to a third aspect of the present invention, in the throttle grip device according to the first or second aspect, the biasing force applying means rotates with the interlocking member when the throttle grip is positively rotated, to thereby perform the second biasing. When the throttle grip is reversely rotated without applying the biasing force of the means to the interlocking member, the stop is caused by coming into contact with the stopper formed on the case while permitting the rotation of the interlocking member, thereby stopping the second attachment. The biasing force of the biasing means can be applied to the interlocking member.

  According to the invention of claim 1, the second biasing means comprises a coil spring linearly housed in the housing portion formed in the interlocking member, and is interposed between the interlocking member and the biasing force applying means. Since the biasing force can be applied, the biasing force can be efficiently generated by the second biasing means attached to the interlocking member, and a plurality of the urging force can be generated along the rotational direction of the interlocking member. Even if the spring load of the biasing means is not so large, a large biasing force can be generated as a whole, and the biasing force by the second biasing means can be generated more efficiently.

  According to the second aspect of the present invention, the second biasing means is constituted by six coil springs disposed along the rotational direction of the interlocking member, so that it is necessary to use a general-purpose coil spring. Spring load can be obtained.

  According to the invention of claim 3, when the throttle grip rotates forward, the urging force applying means rotates with the interlocking member and does not apply the urging force of the second urging means to the interlocking member, and the throttle grip is reversed. When it rotates, it stops by coming into contact with the stopper formed on the case while allowing the rotation of the interlocking member, and the biasing force of the second biasing means can be applied to the interlocking member, so that in the rotational direction of the throttle grip Accordingly, biasing force by the first biasing means or the second biasing means can be appropriately and reliably applied to the interlocking member.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The throttle grip device according to the present embodiment detects the rotation angle of the throttle grip G attached to the handlebar H of a two-wheeled vehicle, as shown in FIG. As shown in FIGS. 2-8, the throttle grip G, the case 1, the interlocking member 2, the biasing force applying means 3, the first biasing means 4, and the second biasing means 5. , The rotation member 6, and the magnetic sensor 7 (rotation angle detection means).

  The case 1 is disposed in the switch case S (see FIG. 1) mounted on the tip end side (base end side of the throttle grip G) of the handlebar H of a two-wheeled vehicle (vehicle). While accommodating the various components to comprise, it hold | maintains the interlocking member 2, the biasing force provision means 3, the rotation member 6 grade | etc., Rotatably. In addition, the code | symbol M in FIG. 1 has shown the switch knob formed in switch case S, and can operate the desired electrical component mounted in the two-wheeled vehicle by operating the desired switch knob M. There is. Further, reference numeral 9 denotes a lid member for closing the opening side of the case 1.

  The throttle grip G is extended from the switch case S and can be rotated while being gripped by the driver. As shown in FIG. 1, the positive rotation a in the predetermined direction around the axis from the initial position a And the reverse rotation b in the opposite direction to the predetermined direction is possible. On the base end side of the throttle grip G, engaging portions Ga (see FIGS. 2 and 10) formed of a pair of projecting portions are formed, and these engaging portions Ga correspond to the engaged portions 2a of the interlocking member 2. By engaging (see FIG. 2 etc.), the throttle grip G and the interlocking member 2 are connected.

  The interlocking member 2 has an engaged portion 2a that can engage with the engaging portion Ga formed on the throttle grip G, and can rotate in conjunction with the forward rotation a and the reverse rotation b of the throttle grip G It is. Specifically, as shown in FIG. 10, the interlocking member 2 according to the present embodiment is an annular member having an engaged portion 2a, a housing portion 2b, a flange 2c, and a gear 2d.

  The engaged portion 2a has a concave shape respectively formed at a position corresponding to the engaging portion Ga of the throttle grip G, and interlocking is performed in a state where the engaging portion Ga is fitted into and engaged with the engaged portion 2a. The base end side of the throttle grip G is connected to the member 2. Thus, the interlocking member 2 can also be rotated with the rotation of the throttle grip G. The engaged portion 2a is formed on the surface of the interlocking member 2 (one surface that can be exposed to the outside when assembled to the case 1), and the other surface is formed with the housing portion 2b. There is. In the other surface of the interlocking member 2, a pair of convex portions 2e each formed in an arc shape is formed.

  The housing portion 2b has a plurality of groove shapes formed at positions between the engaged portions 2a, and the compression coil springs constituting the second biasing means 5 can be housed therein. The flange 2c is formed so as to protrude in the radial direction in the circumferential direction of the interlocking member 2, and the gear 2d is formed over a predetermined range. The gear 2 d is capable of meshing with a gear formed on the outer periphery of the rotating member 6, and the rotating member 6 rotates as the interlocking member 2 rotates.

  The rotating member 6 can rotate in conjunction with the interlocking member 2 as described above, and is housed in the housing recess 1c (see FIG. 9) formed at a predetermined position of the case 1, and the shaft L (FIG. 6) And 8) are rotatable. Thus, when the interlocking member 2 is rotated, the rotating member 6 is rotated at a rotation angle corresponding to the rotation angle. A magnet m is attached to the rotating member 6, and the direction of the magnetic field generated from the magnet m is changed as the rotating member 6 rotates.

  As shown in FIG. 6, the magnetic sensor 7 (rotational angle detection means) comprises a sensor disposed at a position on the extension of the axis L of the rotary member 6, and the magnetic sensor 7 produces magnetic from the magnet m attached to the rotary member 6. The rotation angle of the throttle grip G can be detected by detecting a change in (a change in the direction of the magnetic field). Specifically, the magnetic sensor 7 can obtain an output voltage according to a change in the magnetic field (change in magnetic flux density) of the magnet m, and is, for example, a Hall element (specifically, a magnetic sensor utilizing a Hall effect) Is constituted by 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 7 according to the present embodiment is formed on the printed circuit board 8 on which a predetermined electric circuit is printed.

  Thus, when the interlocking member 2 rotates in the same direction as the throttle grip G rotates forward a, the rotating member 6 also interlocks and rotates according to the gear ratio (the gear ratio of the interlocking member 2 and the rotating member 6) The magnet m attached to the rotating member 6 also rotates by the same angle in the same direction. Thereby, the magnetic field changes according to the rotation angle, so that an output voltage corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 2 (that is, the rotation angle of the throttle grip G) is detected based on the output voltage. It is possible to do. The rotation angle of the throttle grip G thus detected is transmitted as an electrical signal to an ECU (engine control unit) mounted on a two-wheeled vehicle, and the rotation angle of the throttle grip G is transmitted according to the transmitted rotation angle. The engine can be controlled.

  On the other hand, when the interlocking member 2 rotates in the same direction as the throttle grip G reversely rotates b, the rotating member 6 also interlocks and rotates according to the gear ratio (the gear ratio of the interlocking member 2 and the rotating member 6) The magnet m attached to the rotating member 6 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.

  As described above, when the reverse rotation b of the throttle grip G is detected, it is possible to activate or deactivate a predetermined function of the two-wheeled vehicle. In this embodiment, the present invention is applied to a two-wheeled vehicle equipped with a constant vehicle speed holding device (auto cruise device) for keeping the traveling speed constant, and reverse rotation b of the throttle grip G (forward rotation a of fully opening the throttle from the initial position The rotation control in the direction opposite to the direction (1) is configured to be able to stop (cancel) the holding control of the constant vehicle speed.

  Thus, in the interlocking member 2 according to the present embodiment, a plurality of second biasing means 5 formed of a coil spring are accommodated in the inside (in the accommodating portion 2b in the present embodiment), and the interlocking member 2 is a throttle grip The function of transmitting the rotational force of G and the function of accommodating the second biasing means 5 are combined.

  The first biasing means 4 is a torsion coil spring, and is a return spring for biasing the interlocking member 2 toward the initial position when the throttle grip G rotates forward a. That is, when the throttle grip G is rotated forward a, the interlocking member 2 rotates against the urging force of the first urging means 4, and the urging force is transmitted to the throttle grip G, and the throttle grip G is set to the initial position. The return force acts.

  The second biasing means 5 comprises a plurality of coil springs housed in the housing portion 2b of the interlocking member 2, and biases the interlocking member 2 toward the initial position when the throttle grip G reversely rotates b. It is a thing. That is, when the throttle grip G is reversely rotated b, the interlocking member 2 rotates against the urging force of the second urging means 5, and the urging force is transmitted to the throttle grip G, and the throttle grip G is set to the initial position. The return force acts.

  The biasing force applying means 3 does not apply the biasing force of the second biasing means 5 to the interlocking member 2 when the throttle grip G rotates forward a (at this time, only the biasing force of the first biasing means 4 is interlocked The biasing force of the second biasing means 5 can be applied to the interlocking member 2 when the throttle grip G is reversely rotated b). Specifically, as shown in FIG. 11, the biasing force applying means 3 includes a pair of projecting portions 3a, a spring receiver 3b for receiving one end 5a of the second biasing means 5, and an abutment portion 3c. And an annular member having

  An abutting portion 3c further projecting in the outer diameter direction is formed on one of the pair of projecting portions 3a. Then, in a state where the biasing force application means 3 is assembled to the interlocking member 2, as shown in FIG. 13, the gap where the contact portion 3c is formed with the pair of convex portions 2e (the end 2ea of one convex portion 2e And the end 2eb of the other protrusion 2e), and when the interlocking member 2 rotates forward a, as shown in FIG. 14, the end 2ea of the protrusion 2e is one of the contact portions 3c. The end face 3 ca is pressed, and the biasing force applying means 3 is rotated together with the interlocking member 2. On the other hand, when the interlocking member 2 is reversely rotated b, as shown in FIG. 15, although the end 2eb of the other convex portion 2e rotates until it abuts on the other end face 3cb of the abutting portion 3c, In the meantime, since the other end face 3ca is not pressed, the biasing force applying means 3 is stopped while permitting the rotation of the interlocking member 2.

  The spring receiver 3b is located in the housing portion 2b of the interlocking member 2 in a state where the biasing force application means 3 is attached to the interlocking member 2, and as shown in FIG. 7, the spring receiver 3b is housed in the housing portion 2b. It can receive the end 5 a side of the second biasing means 5. The second biasing means 5 is assembled such that one end 5a is supported by the spring receiver 3b and the other end 5b is in contact with the edge wall of the housing portion 2b. When 3 and 3 rotate together (see FIG. 14), the biasing force by the second biasing means 5 does not act, and when the biasing force applying means 3 stops while the interlocking member 2 rotates (see FIG. 15), The second biasing means 5 is compressed to apply a biasing force to the interlocking member 2.

  Further, the contact portion 3c is formed of a portion integrally formed so as to project integrally in the radial direction of the biasing force applying means 3, and when the interlocking member 2 is reversely rotated b, as shown in FIG. It can come in contact with the formed stopper 1a. Thereby, even if the interlocking member 2 is reversely rotated b and receives a reaction force by the urging force of the second urging means 5, the stop state of the urging force applying means 3 is held.

  By the way, while the first biasing means 4 is locked to the locking portion 2 f (see FIG. 10) formed at the one end 4 a of the interlocking member 2, the locking groove 1 b is formed at the other end 4 b in the case 1. (See FIG. 9) When the interlocking member 2 rotates forward and rotates with the biasing force applying means 3, as shown in FIG. 14, one end 4a is pressed against the end 2ec of the convex portion 2e. A biasing force can be applied to the interlocking member 2 and the biasing force applying means 3. On the other hand, when the interlocking member 2 is reversely rotated b, as shown in FIG. 15, one end 4a of the first biasing means 4 is between the convex portions 2e (the end 2ed of one convex portion 2e and the other convex portion 2e The state in which it is positioned between the end 2ec and the end 2ec) is held and not pressed, and the biasing force of the first biasing means 4 is not applied.

  Thus, when the throttle grip G rotates forward a, the biasing force applying means 3 according to the present embodiment rotates with the interlocking member 2 to apply the biasing force of the second urging means 5 to the interlocking member 2. (The biasing force of the first biasing means 4 is applied), and when the throttle grip G rotates in the reverse direction b, the stopper 1a formed on the case 1 and the contact portion 3c while allowing the rotation of the interlocking member 2 Is stopped by being in contact and the biasing force of the second biasing means 5 can be applied to the interlocking member 2 (the biasing force of the first biasing means 4 is not applied). Thereby, depending on the rotational direction of the throttle grip G, the biasing force by the first biasing means 4 or the second biasing means 5 can be appropriately and reliably applied to the interlocking member 2.

  Here, as shown in FIG. 12, the second urging means 5 according to the present embodiment includes a plurality of (six in the present embodiment) linearly accommodated in the accommodation portion 2 b formed in the interlocking member 2. The coil spring is disposed between the interlocking member 2 and the biasing force applying means 3 to be capable of applying a biasing force. More specifically, the second biasing means 5 according to the present embodiment comprises coil springs respectively disposed in the plurality of (six) housing portions 2b formed in the rotational direction of the interlocking member 2, and One end 5a of each coil spring is in contact with the spring receiver 3b of the biasing means 3 and the other end 5b is assembled in contact with the edge wall surface of the housing portion 2b.

  And each coil spring which comprises the 2nd biasing means 5 is accommodated in linear form (shape which can not be bent in an arc) in the accommodating part 2b, as shown in FIG. 12, The throttle grip G is reverse When the interlocking member 2 is rotated in the same direction by rotation b, the linear member is maintained while being compressed, and a biasing force can be applied to the interlocking member 2. As a result, it is possible to suppress the occurrence of loss (loss of spring load) in the obtained spring load as compared with the coil spring disposed in an arc shape, and it is possible to suppress excessive sliding resistance.

  According to the present embodiment, the second biasing means 5 comprises a coil spring linearly housed in the housing portion 2 b formed in the interlocking member 2, and between the interlocking member 2 and the biasing force applying means 3. Since the biasing force can be applied by interposing, the biasing force by the second biasing means 5 attached to the interlocking member 2 is efficiently generated as compared with the case where the second biasing means 5 is disposed in an arc shape. be able to. At the same time, since the second biasing means 5 according to the present embodiment is disposed on the interlocking member 2, the device can be miniaturized as compared with the case in which the second biasing means 5 is disposed on a separate part. Can.

  In addition, since a plurality of second biasing means 5 according to the present embodiment are formed in the rotational direction of the interlocking member 2, the entire second biasing means 5 does not require much spring load as a whole. A large biasing force can be generated, and the biasing force of the second biasing means 5 can be generated more efficiently. However, since a plurality of (six in the present embodiment) second urging means 5 are disposed, one urging force can be reduced, and the second urging to the housing portion 2b at the time of assembling of the apparatus The storage operation of the means 5 can be easily performed. Furthermore, since the second biasing means 5 according to the present embodiment is constituted by six coil springs disposed along the rotational direction of the interlocking member 2, it is necessary to use a general-purpose coil spring. Spring load can be obtained.

  Furthermore, the biasing force applying means 3 according to the present embodiment does not apply the biasing force of the second biasing means 5 to the interlocking member 2 by rotating with the interlocking member 2 when the throttle grip G rotates forward a. When the throttle grip G rotates in the reverse direction b, it abuts against the stopper 1a formed on the case 1 while allowing the rotation of the interlocking member 2 to stop and the biasing force of the second biasing means 5 is the interlocking member 2 Therefore, depending on the rotational direction of the throttle grip G, the biasing force of the first biasing means 4 or the second biasing means 5 can be appropriately and reliably applied to the interlocking member 2.

  As mentioned above, although this embodiment was described, the present invention is not limited to this, for example, it is good also as a thing which has a plurality of coil springs which constitute the 2nd energizing means 5, other than six pieces. Further, the first biasing means 4 may be biasing means other than a torsion coil spring (another biasing means for biasing the interlocking member 2 toward the initial position when the throttle grip G rotates forward). Furthermore, the magnetic sensor 7 may be replaced by another sensor (such as a sensor that does not use magnetism) that can detect the rotational angle of the throttle grip G.

  Furthermore, in the present embodiment, when the throttle grip G is reversely rotated, holding control of the constant vehicle speed holding device (auto cruise device) is stopped (canceled). It is sufficient to detect the reverse rotation, as long as it activates or deactivates a predetermined function of the vehicle. The vehicle to which the present invention is applied is not limited to a two-wheeled vehicle as in the present embodiment, but may be applied to another vehicle (for example, an ATV, a snowmobile, etc.) having a handlebar H.

  The second biasing means comprises a coil spring linearly housed in the housing portion formed in the interlocking member, and a plurality of the second urging means are formed along the rotational direction of the interlocking member, and the interlocking member and the biasing force applying means The present invention can be applied to a throttle grip device that can provide an urging force by being interposed between the throttle grip device and the one having a different external shape or to which another function is added.
