  However, the conventional throttle grip device includes a rotation angle detection means configured to include a magnet disposed in the interlocking member and a magnetic sensor that detects a change in magnetic force from the magnet, Since the rotation angle of the throttle grip is detected by the rotation angle detection, the magnet and the second urging means are disposed in the interlocking member, and the interlocking member becomes large and the magnetic sensor Since the arrangement position is limited, there is a problem that the degree of freedom of layout in the apparatus is lowered.

  In order to eliminate such problems, a rotation member that can rotate in conjunction with the interlocking member is provided, and by detecting the rotation angle of the rotation member by the rotation angle detection means and detecting the rotation angle of the throttle grip, Although it is conceivable to arrange the magnet outside the interlocking member, in that case, in addition to the interlocking member that houses the second biasing means, there is a transmission means for transmitting the rotation of the interlocking member to the rotating member for rotation. It becomes necessary. In this case, in addition to the installation space for the rotating member, a space for the transmission means is required separately, and there is a problem that the entire apparatus becomes large.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a throttle grip device that can suppress an increase in size of the device even if a rotating member that interlocks with the interlocking member is provided. .

  According to the first aspect of the present invention, there is provided a throttle grip that can be rotated by a driver, forwardly rotated in a predetermined direction from the initial position, and reversely rotated in a direction opposite to the predetermined direction, and the throttle grip. An interlocking member that has an engaged portion that can engage with the formed engaging portion, and that can rotate in conjunction with forward and reverse rotations of the throttle grip, and a case that rotatably holds the interlocking member. A first urging means for urging the interlocking member toward an initial position when the throttle grip is rotated forward; and an urging of the interlocking member toward an initial position when the throttle grip is reversely rotated. The rotation angle of the throttle grip can be detected by detecting the rotation force of the second urging means, the rotation member that can rotate in conjunction with the interlocking member, and the rotation angle of the rotation member. A rotation angle detection means, and the vehicle engine can be controlled in accordance with the rotation angle of the throttle grip detected by the rotation angle detection means at the time of forward rotation, and when the throttle grip rotates reversely. A throttle grip device capable of activating or deactivating a predetermined function of a vehicle, wherein the interlocking member constitutes a transmission means having a gear for transmitting the rotational force of the throttle grip to the rotating member. The second urging means is accommodated in the interior.

  According to a second aspect of the present invention, in the throttle grip device according to the first aspect, when the throttle grip rotates forward, the urging force of the second urging means is not applied to the interlocking member, and the throttle grip is reversed. An urging force applying means capable of applying an urging force of the second urging means to the interlocking member when rotated is provided.

  According to a third aspect of the present invention, in the throttle grip device according to the second aspect, the urging force applying means is attached with the second urging means, and rotates together with the interlocking member when the throttle grip rotates forward. The biasing force of the second biasing means is not applied to the interlocking member, and when the throttle grip rotates reversely, it stops by contacting with a stopper formed on the case while allowing the interlocking member to rotate. Then, the urging force of the second urging means can be applied to the interlocking member.

  According to a fourth aspect of the present invention, in the throttle grip device according to the third aspect, the interlocking member has a flange in which the gear is formed over a predetermined range, and the biasing force that contacts the stopper and the stopper. The contact portion of the applying means is formed at a position corresponding to the flange.

Therefore, even if a rotating member that interlocks with the interlocking member is provided, it is possible to prevent the apparatus from becoming large.

  According to the invention of claim 2, when the throttle grip is rotated forward, the urging force of the second urging means is not applied to the interlocking member, and when the throttle grip rotates reversely, the urging force of the second urging means is applied. Since the urging force applying means capable of applying the urging force to the interlocking member is provided, the first urging means and the second urging means can be selectively operated according to the rotation direction of the throttle grip.

  According to the invention of claim 3, when the second urging means is attached and the throttle grip rotates in the forward direction, the urging force applying means rotates together with the interlocking member, and the urging force of the second urging means is related to the interlocking member. When the throttle grip rotates reversely without being applied to the member, it stops by contacting the stopper formed on the case while allowing the rotation of the interlocking member, and applies the biasing force of the second biasing means to the interlocking member Therefore, the urging force by the first urging means or the second urging means can be appropriately and reliably applied to the interlocking member according to the rotation direction of the throttle grip.

  According to the invention of claim 4, the interlocking member has a flange in which the gear is formed over a predetermined range, and the contact portion of the biasing force applying means that contacts the stopper and the stopper is located at a position corresponding to the flange. Since it is formed, the stopper and the contact portion can be formed within the diameter of the interlocking member, and the radial dimension of the throttle grip device can be reduced.

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

  The case 1 is disposed in a switch case S (see FIG. 1) attached to the front end side (the base end side of the throttle grip G) of the handlebar H of a motorcycle (vehicle). While accommodating the various components which comprise, the interlocking member 2, the urging | biasing force provision means 3, the rotation member 6, etc. are rotatably hold | maintained. In addition, the code | symbol M in FIG. 1 has shown the switch knob formed in the switch case S, By operating the desired switch knob M, the desired electrical equipment mounted in the two-wheeled vehicle can be operated now. Yes. 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 held by the driver. As shown in FIGS. The rotation a and the reverse rotation b opposite to the predetermined direction are possible. On the base end side of the throttle grip G, an engaging portion Ga (see FIGS. 2 and 10) including a pair of projecting portions is formed, and these engaging portions Ga are engaged portions 2a of the interlocking member 2. By engaging with (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 be engaged with an 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 has an annular shape having a pair of engaged portions 2a, a pair of accommodating portions 2b, a flange 2c, and a gear 2d. It consists of members.

  The engaged portion 2a has a concave shape formed at a position corresponding to the engaging portion Ga of the throttle grip G, and is interlocked with the engaged portion 2a fitted and engaged with the engaged portion 2a. The base end side of the throttle grip G is connected to the member 2. Thereby, the interlocking member 2 can also rotate 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 housing portion 2b is formed on the other surface. Yes. It should be noted that a pair of convex portions 2 e each formed in an arc shape is formed on the other surface of the interlocking member 2.

  The accommodating portion 2b has a groove shape formed in an arc shape at a position between the pair of engaged portions 2a, and a compression coil spring constituting the second urging means 5 can be accommodated therein. Yes. The flange 2c is formed to protrude in the radial direction over the entire circumferential direction of the interlocking member 2, and a gear 2d is formed over a predetermined range. The gear 2d can be engaged with a gear formed on the outer periphery of the rotating member 6, and the rotating member 6 rotates with the rotation of the interlocking member 2.

  The rotating member 6 can rotate in conjunction with the interlocking member 2 as described above, and is accommodated in the accommodating recess 1c (see FIG. 9) formed at a predetermined position of the case 1, and the shaft L (FIG. 2). , 6). Thus, when the interlocking member 2 rotates, the rotating member 6 rotates at a rotation angle corresponding to the rotation angle. A magnet m is attached to the rotating member 6, and the magnetic force generated from the magnet m changes as the rotating member 6 rotates.

  As shown in FIG. 6, the magnetic sensor 7 (rotation angle detection means) is composed of a sensor disposed at a position on an extension line of the axis L of the rotating member 6, and the magnetism generated from the magnet m attached to the rotating member 6. The rotation angle of the throttle grip G can be detected by detecting this change. Specifically, the magnetic sensor 7 can obtain an output voltage in accordance with a magnetic field change (change in magnetic flux density) of the magnet m. For example, a Hall element (specifically, a magnetic sensor using the Hall effect). Is constituted by a linear Hall IC 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 a printed board 8 on which a predetermined electric circuit is printed.

  Accordingly, when the interlocking member 2 rotates in the same direction as the throttle grip G rotates in the forward direction a, the rotating member 6 also rotates in conjunction with the magnet m attached to the rotating member 6 in the same direction. Rotate by an angle. Thereby, since the magnetic field changes depending on the rotation angle, 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 detected rotation angle of the throttle grip G is transmitted as an electric signal to an ECU (Engine Control Unit) mounted on the two-wheeled vehicle, and according to the transmitted rotation angle of the throttle grip G of the vehicle. The engine can be controlled.

  On the other hand, when the interlocking member rotates in the same direction as the throttle grip G rotates in the reverse direction b, the rotating member 6 also rotates in conjunction with each other, and the magnet m attached to the rotating member 6 also has the same angle in the same direction. Rotate. 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 reverse rotation b of the throttle grip G can be detected.

  Thus, 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. In the present embodiment, the present invention is applied to a two-wheeled vehicle equipped with a constant vehicle speed holding device (auto cruise device) that keeps the traveling speed constant, and the throttle grip G is reversely rotated b (forward rotation a that fully opens the throttle from the initial position a). When the rotation operation is performed in the direction opposite to the direction (1), the constant vehicle speed holding control can be stopped (cancelled).

  Thus, the interlocking member 2 according to the present embodiment constitutes a transmission means in which a gear 2d for transmitting the rotational force of the throttle grip G to the rotating member 6 is formed, and the inside thereof (in the present embodiment, accommodated). The second urging means 5 is accommodated in the part 2b), and the interlocking member 2 has both a function of transmitting the rotational force of the throttle grip G and a function of accommodating the second urging means 5. Has been.

  In addition, the interlocking member 2 according to the present embodiment has a flange 2c in which the gear 2d is formed over a predetermined range, and as shown in FIGS. 12 to 14, a biasing force is applied to contact the stopper 1a and the stopper 1a. The contact portion 3c of the means 3 is formed at a position corresponding to the flange 2c. Thereby, the stopper 1a and the contact part 3c can be stored in the diameter of the flange 2c of the interlocking member 2, and it can contribute to size reduction.

  The first urging means 4 is composed of a torsion coil spring, and urges the interlocking member 2 toward the initial position when the throttle grip G rotates in the forward direction 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, so that the urging force is transmitted to the throttle grip G, and the throttle grip G is brought to the initial position. The returning force acts.

  The second urging means 5 is composed of a pair of coil springs, and urges the interlocking member 2 toward the initial position when the throttle grip G rotates in the reverse direction b. That is, when the throttle grip G is rotated in the reverse direction b, the interlocking member 2 rotates against the urging force of the second urging means 5, so that the urging force is transmitted to the throttle grip G, and the throttle grip G is brought to the initial position. The returning force acts.

  When the second urging means 5 is attached and the throttle grip G rotates forward a, the urging force applying means 3 does not apply the urging force of the second urging means 5 to the interlocking member 2 (at this time, the first Only the urging force of the urging means 4 is applied to the interlocking member), and the urging force of the second urging means 5 can be applied to the interlocking member 2 when the throttle grip G rotates in the reverse direction b. Specifically, as shown in FIG. 11, the urging force applying means 3 includes a pair of protrusions 3a, a pair of spring receivers 3b for receiving the one end 5a side of the second urging means 5, and a contact portion. And an annular member having 3c.

  One of the pair of projecting portions 3a is formed with a contact portion 3c further projecting in the outer diameter direction. Then, in a state where the biasing force applying means 3 is assembled to the interlocking member 2, as shown in FIG. 12, the contact portion 3c is a gap in which a pair of convex portions 2e are formed (the end portion 2ea of one convex portion 2e). And the end 2eb of the other convex portion 2e) and when the interlocking member 2 is rotated forward a, the end 2ea of the convex portion 2e becomes one of the contact portions 3c as shown in FIG. The urging force applying means 3 is rotated together with the interlocking member 2 by pressing the end surface 3ca. On the other hand, when the interlocking member 2 rotates in the reverse direction b, as shown in FIG. 14, it rotates until the end 2eb of the other convex portion 2e comes into contact with the other end surface 3cb of the contact portion 3c. In the meantime, since the other end surface 3ca is not pressed, the biasing force applying means 3 is stopped while allowing the interlocking member 2 to rotate.

  The spring receiver 3b is located in the accommodating portion 2b of the interlocking member 2 in a state in which the biasing force applying means 3 is attached to the interlocking member 2, and is accommodated in the accommodating portion 2b as shown in FIG. The one end 5a side of the second urging means 5 can be received. The second urging means 5 is assembled such that one end 5a is supported by the spring receiver 3b and the other end 5b abuts against the edge wall surface of the accommodating portion 2b. 3 (see FIG. 13), the urging force by the second urging means 5 does not act, and the urging force applying means 3 stops while the interlocking member 2 rotates (see FIG. 14). The urging means 5 is compressed so that the urging force is applied to the interlocking member 2.

  Further, the abutting portion 3c is composed of a portion integrally formed so as to protrude in the radial direction of the urging force applying means 3, and when the interlocking member 2 rotates in the reverse direction b, as shown in FIG. It can come into contact with the formed stopper 1a. Thereby, even if the interlocking member 2 rotates reversely b and receives a reaction force due to the urging force of the second urging means 5, the stop state of the urging force applying means 3 is maintained.

  By the way, the first urging means 4 has one end 4 a locked to a locking portion 2 f (see FIG. 10) formed on the interlocking member 2 and the other end 4 b formed to the locking groove 1 b formed on the case 1. (See FIG. 8), when the interlocking member 2 rotates forward a and rotates together with the biasing force applying means 3, one end 4a is pressed against the end 2ec of the convex portion 2e as shown in FIG. The urging force can be applied to the interlocking member 2 and the urging force applying means 3. On the other hand, when the interlocking member 2 rotates in the reverse direction b, as shown in FIG. 14, one end 4a of the first biasing means 4 is located between the convex portions 2e (the end portion 2ed of one convex portion 2e and the other convex portion 2e. The position positioned between the first biasing means 4 and the first biasing means 4 is not applied, and the biasing force of the first biasing means 4 is not applied.

  As described above, the urging force applying means 3 according to the present embodiment is attached with the second urging means 5 and rotates together with the interlocking member 2 when the throttle grip G rotates in the forward direction a. No biasing force is applied to the interlocking member 2 (the biasing force of the first biasing means 4 is applied), and the throttle member G is formed in the case 1 while allowing the interlocking member 2 to rotate when the throttle grip G rotates in the reverse direction b. The stopper 1a and the abutting portion 3c that are in contact with each other can stop and a 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). It is like that. Thereby, the urging force by the first urging means 4 or the second urging means 5 can be appropriately and reliably applied to the interlocking member 2 according to the rotation direction of the throttle grip G.

  Here, in the present embodiment, the engaging portion Ga of the throttle grip G and the engaged portion 2a of the interlocking member 2 are plural at equal intervals in the rotational direction of the throttle grip G (2 in the present embodiment). The second urging means 5 are respectively disposed at positions between the engaged portions 2 a of the interlocking member 2. Thus, when the throttle grip G is rotated and when the throttle grip G returns to the initial position by the urging force of the second urging means 5, the rotation of the interlocking member 2 is stabilized and the operability of the throttle grip G is improved. Can do.

  However, in this embodiment, the engagement portion Ga of the throttle grip G and the engaged portion 2a of the interlocking member 2 are formed at equal intervals over the rotation direction of the throttle grip G. It is sufficient if a plurality of the grips are formed at equal intervals in the rotation direction of the throttle grip G. For example, three or more are formed, and the second urging means 5 is disposed at a position between the engaged portions 2a. It is good.

  When the throttle grip G rotates forward, the urging force of the second urging means 5 is not applied to the interlocking member 2, and when the throttle grip G rotates reversely, the urging force of the second urging means 5 is applied to the interlocking member. 2 is provided, the first urging means 4 and the second urging means 5 can be selectively operated according to the rotation direction of the throttle grip G. Therefore, smoother rotation operation of the throttle grip G can be performed, and operability can be further improved.

  Further, since the second urging means 5 according to the present embodiment is composed of a coil spring that extends in an arc shape at a position between the engaged portions 2a of the interlocking member 2, the second urging means 5 is provided. When the throttle grip G returns to the initial position due to the urging force, it is possible to further stabilize the rotation of the interlocking member 2 and further improve the operability of the throttle grip G. However, since a plurality (two in the present embodiment) of the second urging means 5 are disposed, one urging force can be reduced, and the second urging against the housing portion 2b when the apparatus is assembled. The accommodation work of the means 5 can be easily performed.

  In addition, according to the present embodiment, the interlocking member 2 constitutes the transmission means in which the gear 2d for transmitting the rotational force of the throttle grip G to the rotating member 6 is formed, and the second urging force is formed therein. Since the means 5 is accommodated, even if the rotating member 6 interlocked with the interlocking member 2 is provided, an increase in the size of the apparatus can be suppressed. Further, since the rotation of the rotating member 6 interlocked with the interlocking member 2 is detected by the magnetic sensor 7 (rotation angle detecting means) and the rotation angle of the throttle grip G is detected, it is necessary to form a magnet m or the like on the interlocking member 2. Therefore, a sufficient installation space for the second urging means 5 can be secured.

  Further, the interlocking member 2 according to the present embodiment has a flange 2c in which the gear 2d is formed over a predetermined range, and the contact portion 3c of the biasing force applying means 3 that contacts the stopper 1a and the stopper 1a is a flange. Since it is formed at a position corresponding to 2c, the stopper 1a and the contact portion 3c can be formed within the diameter of the interlocking member 2, and the dimension of the throttle grip device in the radial direction can be reduced.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, the first biasing means 4 is biased by a biasing means other than the torsion coil spring (when the throttle grip G rotates forward, the interlocking member 2 The second urging means 5 may be an urging means other than the coil spring (when the throttle grip G rotates in the reverse direction), the interlocking member 2 is brought to the initial position. It is good also as another urging means to urge toward. Further, instead of the magnetic sensor 7, another sensor (such as a sensor that does not use magnetism) that can detect the rotation angle of the throttle grip G may be used.

  Further, in the present embodiment, when the throttle grip G is rotated in the reverse direction, the constant vehicle speed holding control of the constant vehicle speed holding device (auto cruise device) is stopped (cancelled). If the rotation of the direction is detected, it is sufficient if the predetermined function of the vehicle is activated or deactivated. For example, rotation of the throttle grip G in the reverse direction may start authentication in the immobilizer system or smart entry system, operate a starter that starts the engine, or operate emergency lighting means such as a hazard. The applied vehicle is not limited to a two-wheeled vehicle as in this embodiment, and may be applied to other vehicles having a handlebar H (for example, ATV, snowmobile, etc.).

  The interlocking member constitutes a transmission means in which a gear for transmitting the rotational force of the throttle grip to the rotation member is formed, and if it is a throttle grip device in which the second urging means is accommodated, the external shape The present invention can also be applied to those having different functions or those having other functions added.
