Embodiments of the present invention will be specifically described below with reference to the drawings.
As shown in FIGS. 1 and 2, the throttle grip device according to the first embodiment detects the rotation angle of a throttle grip G attached to a handlebar H of a two-wheeled vehicle, and transmits the detection signal to an ECU or the like mounted on the two-wheeled vehicle. As shown in FIGS. 2 to 15, the device is for sending data to an electronic control device, and as shown in FIGS. 1 biasing means 5, second biasing means 6, and resistance force applying means 7.

The case 1 is disposed within a housing case C (see Figs. 1 and 2) attached to the tip side of the handlebar H (base end side of the throttle grip G) of a two-wheeled vehicle (vehicle). It accommodates various parts constituting the grip device, and also rotatably holds the interlocking member 2 and the rotating member 3. Specifically, as shown in FIGS. 7 and 8, the case 1 according to the present embodiment includes a first housing recess 1a, a second housing recess 1b, and a third housing recess 1c. In addition, the code|symbol 8 has shown the cover member which covers the peripheral part of the interlocking member 2 and the rotating member 3.

As shown in FIGS. 5 and 6, the interlocking member 2 and the rotating member 3 are rotatably assembled in the first housing recess 1a and the second housing recess 1b, respectively, and the third housing recess 1c is rotatably assembled in the third housing recess 1c as shown in FIGS. As shown in 9, a plurality of springs s and resistance force applying means 7 are assembled. Further, the resistance force applying means 7 is pressed by the biasing force of the spring s against the surface f of the interlocking member 2 assembled in the first housing recess 1a, and slides on the surface f when the interlocking member 2 rotates. It is designed to give resistance by moving.

The throttle grip G can be rotated while being held by the driver, and as shown in FIGS. 1 and 2, it can be rotated in a forward direction a in a predetermined direction around an axis La from an initial position and in a direction opposite to the predetermined direction. Reverse rotation b in the direction is possible. As shown in FIG. 15, a pair of engaging portions Ga are formed on the base end side of the throttle grip G, and these engaging portions Ga engage with the engaged portion 2a of the interlocking member 2 (see FIG. 3 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 an engaging portion Ga formed on the throttle grip G, and is connected to the throttle grip G, and also rotates the throttle grip G forwardly a and reversely. It can rotate in conjunction with b. Specifically, as shown in FIGS. 12 to 14, the interlocking member 2 according to this embodiment has an engaged portion 2a formed on one surface, and a first biasing means 5 on the other surface. It is made of an annular member in which a first annular accommodating portion 2c for accommodating the second biasing means 6 and a second annular accommodating portion 2d for accommodating the second biasing means 6 are formed.

Further, in this embodiment, the second accommodating part 2d is located on the outer diameter side than the first accommodating part 2c, and the second biasing means 6 is disposed on the outer diameter side than the first biasing means 5. It is now set up. Furthermore, in this embodiment, the first accommodating part 2c and the second accommodating part 2d are divided (defined) by a wall 2e integrally formed with the interlocking member 2, and the first urging means 5 and the second accommodating part 2d The two biasing means 6 are configured to be securely held in the first accommodating part 2c and the second accommodating part 2d, respectively.

Furthermore, a gear portion 2b that meshes with a gear formed on the outer peripheral surface of the rotating member 3 is formed on the side surface of the interlocking member 2. When the interlocking member 2 rotates due to the rotational operation of the throttle grip G, the rotational force is transmitted to the rotating member 3 via the gear portion 2b. The rotating member 3 can rotate in conjunction with the interlocking member 2, and when the interlocking member 2 rotates, it rotates about the axis Lb to a rotation angle corresponding to the rotation angle. As shown in FIG. 6, this rotating member 3 is attached with a magnet m, and is configured so that the magnetic force generated from the magnet m changes as the rotating member 3 rotates.

The magnetic sensor 4 (rotation angle detection means), as shown in FIG. By detecting the change in the rotation angle of the throttle grip G, it is possible to detect the rotation angle of the throttle grip G. Specifically, the magnetic sensor 4 is capable of obtaining an output voltage according to a change in the magnetic field (change in magnetic flux density) of the magnet m, and includes, for example, a Hall element (specifically, a magnetic sensor using the Hall effect). is composed of a linear Hall IC (Linear Hall IC) etc. that can obtain an output voltage proportional to the magnetic field (magnetic flux density) of the magnet m.

Therefore, when the interlocking member 2 rotates in the same direction as the throttle grip G rotates forward a, the rotating member 3 also rotates in conjunction, and the magnet m attached to the rotating member 3 also rotates with the rotating member 3. Rotate by the same angle in the same direction. As a result, the magnetic field changes depending on the rotation angle, so an output voltage corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 2 (i.e., the rotation angle of the throttle grip G) can be detected based on the output voltage. It is considered possible to do so. The rotation angle of the throttle grip G detected in this way is transmitted as an electrical signal to the 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 now be controlled.

On the other hand, when the interlocking member rotates in the same direction as the throttle grip G reversely rotates b, the rotating member 3 also rotates in conjunction, and the magnet m attached to the rotating member 3 also moves in the same direction as the rotating member 3. rotate by the same angle. As a result, the magnetic field changes depending on the rotation angle, so 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 maintenance device (auto cruise device) that maintains a constant running speed, and the throttle grip G is rotated in reverse b (forward rotation a to fully open the throttle from the initial position). When the rotational operation is performed in a direction opposite to the direction of , the constant vehicle speed maintenance control can be stopped (cancelled).

The first urging means 5 is for urging the interlocking member 2 and the throttle grip G toward the initial position when the throttle grip G rotates forward a, and as shown in FIG. and the other end 5c. As shown in FIGS. 8 and 14, the first biasing means 5 has a coil part 5a accommodated in the first housing part 2c of the interlocking member 2, and the other end 5c of the first biasing means 5 in the locking part 2g of the interlocking member 2. It is designed to be locked.

The second biasing means 6 biases the interlocking member 2 and the throttle grip G toward the initial position when the throttle grip G rotates in the reverse direction b, and as shown in FIG. and the other end 6c. As shown in FIGS. 8 and 14, the second biasing means 6 has a coil portion 6a accommodated in a second accommodating portion 2d of the interlocking member 2, and the other end 6c of the second biasing means 6 located in the locking portion 2f of the interlocking member 2 ( Specifically, it is configured to be locked to the other side surface 2fb of the locking portion 2f.

In this embodiment, the diameter (wire diameter) of the wire constituting the second biasing means 6 is larger than the diameter (wire diameter) of the wire constituting the first biasing means 5. The number of turns of the coil portion 6a constituting the second biasing means 6 is smaller than the number of turns of the coil portion 6a constituting the first biasing means 5. Therefore, since the urging force (stress) generated by the second urging means 6 can be set larger than the urging force (stress) generated by the first urging means 5, the rotational operation for the forward rotation a of the throttle grip G This can be performed smoothly, and the reverse rotation b of the throttle grip G can be prevented from being unintentionally performed.

On the other hand, as shown in FIGS. 7 and 8, the case 1 according to the present embodiment has a locking portion 1e that locks one end 5b of the first urging means 5, and a locking portion 1e that locks one end 6b of the second urging means 6. A locking portion 1d for locking is formed. However, the locking portion 1e locks one end 5b of the first biasing means 5 in the direction of forward rotation a, and locks the one end 5b of the first biasing means 5 in the direction of reverse rotation b. At the same time, the locking portion 1d does not lock one end 6b of the second biasing means 6 in the direction of forward rotation a, and in the direction of reverse rotation b. One end 6b of the second biasing means 6 is locked against the second biasing means 6.

Further, the locking portion 2f of the interlocking member 2 according to the present embodiment is formed of a protruding portion that is integrally formed on the interlocking member 2 and has one side surface 2fa and the other side surface 2fb, so that the interlocking member 2 is When the rotation a is performed, one side surface 2fa of the locking portion 2f presses one end 6b of the second biasing means 6 locked by the locking portion 1d, causing the one end 6b to follow the rotation of the interlocking member 2. When the interlocking member 2 rotates backward b, the other end 6c of the second biasing means 6, which is locked to the other side surface 2fb of the locking portion 2f, follows the rotation of the interlocking member 2.

As a result, when the throttle grip G rotates forward a, the first biasing means 5 has one end 5b locked with the locking part 1e and fixed to the case 1, and the other end 5c locked with the locking part 2g. As a result, the coil portion 5a is twisted and urges the interlocking member 2 and the throttle grip G toward the initial position. On the other hand, when the throttle grip G rotates in the reverse direction b, the first biasing means 5 is in a state in which the other end 5c is locked by the locking portion 2g and follows the rotation of the interlocking member 2, but the one end 5b is free ( Since the coil portion 5a is not twisted and rotates together with the interlocking member 2, no urging force is generated.

Furthermore, when the throttle grip G rotates in the reverse direction b, the second biasing means 6 has one end 6b locked with the locking part 1d and fixed to the case 1, and the other end 6c facing the other side surface of the locking part 2f. 2fb and follows the rotation of the interlocking member 2, the coil portion 6a is twisted and urges the interlocking member 2 and the throttle grip G toward the initial position. On the other hand, when the throttle grip G rotates forward a, the second biasing means 6 has one end 6b pressed by one side surface 2fa of the locking part 2f, and is released from the locking part 1d of the case 1. Since the rotation of the interlocking member 2 is followed and the other end 6c of the locking portion 2f is kept locked to the other side surface 2fb, the coil portion 5b is not twisted (the second biasing means 6) and the interlocking member 2, so that no biasing force is generated.

Here, the first biasing means 5 and the second biasing means 6 according to the present embodiment are composed of torsion coil springs as described above, and as shown in FIGS. 3 and 6, the first biasing means 5 and the coil portions (5a, 6a) of the second biasing means 6 are arranged on the coaxial circumference (on a concentric circle with the axis La as a common center) while overlapping in the direction of the axis La of the interlocking member 2. . That is, the first biasing means 5 is housed in the first housing part 2c located on the inner diameter side of the interlocking member 2, and the second biasing means 6 is housed in the second housing part 2d located on the outer diameter side of the interlocking member. The first biasing means 5 and the second biasing means 6 are arranged concentrically and overlapping (on top of each other) in the direction of the axis La.

According to this embodiment, the first biasing means 5 and the second biasing means 6 are composed of torsion coil springs, and the coil portions (5a, 6a) of the first biasing means 5 and the second biasing means 6 are are disposed on the coaxial circumference while overlapping in the direction of the axis La of the interlocking member 2, the structure of the first biasing means 5 and the second biasing means 6 is simplified and assembly is facilitated. At the same time, the case 1 can be made thinner (the thickness of the case 1 can be reduced). In particular, since the coil parts (5a, 6a) of the first biasing means 5 and the second biasing means 6 are disposed on the same axial circumference, the first biasing means 5 and the second biasing means 6 are attached to the case 1 and the interlocking member 2. The two biasing means 6 can be assembled at once, and the assembly work efficiency can be further improved.

Furthermore, since the second biasing means 6 according to the present embodiment is disposed on the outer diameter side of the first biasing means 5, the torsion coil spring can have an arbitrarily set wire diameter and number of turns of the coil portion 6a. can be assembled as the second urging means 6, and the urging force applied when the throttle grip G rotates in reverse can be set arbitrarily. Furthermore, the interlocking member 2 according to the present embodiment has a first annular housing part 2c that accommodates the first biasing means 5 and a second annular housing part 2d that accommodates the second biasing means 6. Since the first accommodating part 2c and the second accommodating part 2d are separated by the wall 2e formed integrally with the interlocking member 2, the first biasing means 5 and the second biasing means 6 can be positioned accurately. It can be assembled by hand.

Furthermore, the interlocking member 2 is provided with a rotating member 3 that can rotate in conjunction with the interlocking member 2, and the interlocking member 2 is formed with a gear portion 2b for transmitting the rotational force of the throttle grip G to the rotating member 3. The interlocking member 2 can have both the function of accommodating the first urging means 5 and the second urging means 6 and the function of transmitting rotational force to the rotating member 3.

In particular, in the second biasing means 6 according to this embodiment, when the throttle grip G rotates in the reverse direction b, the coil portion 6a is twisted and biases the interlocking member 2 and the throttle grip G toward the initial position, and When the grip G rotates in the forward direction a, the coil portion 6a rotates together with the interlocking member 2 without being twisted, thereby reliably preventing the biasing force from being generated by the second biasing means 6 when the throttle grip G rotates in the forward direction a. can do.

Next, a second embodiment according to the present invention will be described.
Similar to the first embodiment, 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 transmits the detection signal to an electronic control device such as an ECU mounted on the two-wheeled vehicle. As shown in FIGS. 16 to 22, it includes a throttle grip G, a case 9, an interlocking member 10, a rotating member 3, a magnetic sensor 4 (rotation angle detecting means), and a first biasing member. It is comprised of means 5, second biasing means 6, and resistance force applying means 7. Note that the same components as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

The case 9 is disposed within a storage case C (see FIGS. 16 and 17) attached to the tip side of the handlebar H (base end side of the throttle grip G) of the two-wheeled vehicle (vehicle). It accommodates various parts constituting the grip device, and also rotatably holds the interlocking member 10 and the rotating member 3. Specifically, as shown in FIGS. 18 and 19, the case 9 according to this embodiment includes a first housing recess 9a, a second housing recess 9b, and a third housing recess 9c.

Similarly to the first embodiment, the interlocking member 10 and the rotating member 3 are rotatably assembled in the first accommodation recess 9a and the second accommodation recess 9b, and the third accommodation recess 9c has a plurality of The spring s and the resistance force applying means 7 (see the first embodiment) are assembled. Further, the resistance force applying means 7 is pressed by the biasing force of the spring s against the surface f of the interlocking member 10 assembled in the first housing recess 9a, and slides on the surface f when the interlocking member 10 rotates. It is designed to give resistance by moving.

The interlocking member 10 has an engaged portion 10a that can engage with an engaging portion Ga formed on the throttle grip G, and is connected to the throttle grip G, and also rotates the throttle grip G in forward rotation a and reverse rotation. It can rotate in conjunction with b. Specifically, as shown in FIGS. 20 to 22, the interlocking member 10 according to the present embodiment has an engaged portion 10a formed on one surface, and a first biasing means 5 formed on the other surface. It is made of an annular member in which a first annular accommodating portion 10c for accommodating the second biasing means 6 and a second annular accommodating portion 10d for accommodating the second biasing means 6 are formed.

Further, in the present embodiment, the second accommodating portion 10d is located on the outer diameter side than the first accommodating portion 10c, and the second biasing means 6 is disposed on the outer diameter side than the first biasing means 5. It is now set up. Furthermore, in this embodiment, the first accommodating part 10c and the second accommodating part 10d are divided (defined) by a wall 10e integrally formed with the interlocking member 10, and the first urging means 5 and the second accommodating part 10d The two biasing means 6 are configured to be securely held in the first accommodating part 10c and the second accommodating part 10d, respectively.

Like the first embodiment, the first biasing means 5 biases the interlocking member 10 and the throttle grip G toward the initial position when the throttle grip G rotates forward a, as shown in FIG. It consists of a torsion coil spring having a coil portion 5a, one end 5b and the other end 5c. As shown in FIGS. 19 and 22, the first biasing means 5 has a coil portion 5a accommodated in a first accommodating portion 10c of the interlocking member 10, and the other end 5c of the first biasing means 5 in a locking portion 10g of the interlocking member 10. It is designed to be locked.

Similar to the first embodiment, the second biasing means 6 biases the interlocking member 10 and the throttle grip G toward the initial position when the throttle grip G rotates in the reverse direction b, as shown in FIG. It consists of a torsion coil spring having a coil portion 6a, one end 6b and the other end 6c. As shown in FIGS. 19 and 22, the second biasing means 6 has a coil portion 6a accommodated in a second accommodating portion 10d of the interlocking member 10, and the other end 6c of the second biasing means 6 in a locking portion 10f of the interlocking member 10. It is designed to be locked.

On the other hand, the case 9 according to this embodiment has a locking part 9e that locks one end 5b of the first biasing means 5 and one end 6b of the second biasing means 6, as shown in FIGS. A locking portion 9d for locking is formed. However, the locking portion 9e locks one end 5b of the first biasing means 5 in the direction of forward rotation a, and locks the one end 5b of the first biasing means 5 in the direction of reverse rotation b. The locking portion 9d locks one end 6b of the second biasing means 6 in both the forward rotation a direction and the reverse rotation b direction. .

Furthermore, the locking portion 10g of the interlocking member 10 according to the present embodiment is formed of a convex portion integrally formed on the interlocking member 10, and when the interlocking member 10 rotates backward b, the locking portion 10f locks the other end 6c in the same direction. When the other end 6c is pressed in the direction to follow the rotation of the interlocking member 10 and the interlocking member 10 rotates forward a, the locking portion 10f is separated from the other end 6c, and the other end 6c does not follow the interlocking member 10 and remains stationary.

As a result, when the throttle grip G rotates forward a, the first biasing means 5 has one end 5b locked with the locking part 9e and fixed to the case 1, and the other end 5c locked with the locking part 10g. As a result, the coil portion 5a is twisted and urges the interlocking member 10 and the throttle grip G toward the initial position. On the other hand, when the throttle grip G rotates in the reverse direction b, the first biasing means 5 is in a state in which the other end 5c is locked by the locking portion 10g and follows the rotation of the interlocking member 10, but the one end 5b is free ( Since the coil portion 5a is not twisted and rotates together with the interlocking member 10, no urging force is generated.

Further, when the throttle grip G rotates in the reverse direction b, the second biasing means 6 has one end 6b locked with the locking part 9d and fixed to the case 1, and the other end 6c pressed against the locking part 10f. Since it follows the rotation of the interlocking member 10, the coil portion 6a is twisted and urges the interlocking member 10 and the throttle grip G toward the initial position. On the other hand, when the throttle grip G rotates forward a, one end 6b of the second biasing means 6 is locked to the locking part 9d and fixed to the case 1, while the other end 6c is separated from the locking part 10f. Therefore, the coil portion 5b is not twisted (the second biasing means 6) is maintained in a stationary state, and no biasing force is generated.

Here, the first biasing means 5 and the second biasing means 6 according to the present embodiment are made of torsion coil springs as in the first embodiment, and as shown in FIG. 17, the first biasing means 5 The coil portions (5a, 6a) of the second biasing means 6 are arranged on the coaxial circumference (on a concentric circle with the axis La as a common center) while overlapping in the direction of the axis La of the interlocking member 10. . That is, the first biasing means 5 is accommodated in the first housing portion 10c located on the inner diameter side of the interlocking member 10, and the second biasing means 6 is accommodated in the second housing portion 10d located on the outer diameter side of the interlocking member. The first biasing means 5 and the second biasing means 6 are arranged concentrically and overlapping (on top of each other) in the direction of the axis La.

According to this embodiment, the first biasing means 5 and the second biasing means 6 are composed of torsion coil springs, and the coil portions (5a, 6a) of the first biasing means 5 and the second biasing means 6 are are disposed on the same axial circumference while overlapping in the direction of the axis La of the interlocking member 10, which simplifies the configuration of the first biasing means 5 and the second biasing means 6 and facilitates assembly. At the same time, the case 9 can be made thinner (the thickness of the case 9 can be reduced). In particular, since the coil portions (5a, 6a) of the first biasing means 5 and the second biasing means 6 are arranged on the same axial circumference, the first biasing means 5 and the second biasing means 6 are arranged on the case 9 and the interlocking member 10. The two biasing means 6 can be assembled at once, and the assembly work efficiency can be further improved.

Furthermore, since the second biasing means 6 according to the present embodiment is disposed on the outer diameter side of the first biasing means 5, the torsion coil spring can have an arbitrarily set wire diameter and number of turns of the coil portion 6a. can be assembled as the second urging means 6, and the urging force applied when the throttle grip G rotates in reverse can be set arbitrarily. Furthermore, the interlocking member 10 according to the present embodiment has a first annular housing part 10c that accommodates the first biasing means 5 and a second annular housing part 10d that accommodates the second biasing means 6. Since the first accommodating part 10c and the second accommodating part 10d are separated by the wall part 10e integrally formed with the interlocking member 10, the first biasing means 5 and the second biasing means 6 can be positioned accurately. It can be assembled by hand.

Furthermore, since the interlocking member 10 includes the rotating member 3 that can rotate in conjunction with the interlocking member 10, and the gear portion 10b for transmitting the rotational force of the throttle grip G to the rotating member 3, The interlocking member 10 can have both the function of accommodating the first urging means 5 and the second urging means 6 and the function of transmitting rotational force to the rotating member 3.

In particular, in the second biasing means 6 according to this embodiment, when the throttle grip G rotates in the reverse direction b, the coil portion 6a is twisted and biases the interlocking member 10 and the throttle grip G toward the initial position, and When the grip G rotates in the forward direction a, the coil portion 6a is not twisted and remains stationary, so that the biasing force generated by the second biasing means 6 when the throttle grip G rotates in the forward direction a is more reliably prevented. It can be prevented.

Although the present embodiment has been described above, the present invention is not limited to this. For example, a magnet m may be formed on the interlocking member (2, 10) and the rotation angle of the throttle grip G may be detected based on the magnetic change of the magnet m, in which case the rotating member 3 may be unnecessary. Also, in this embodiment, the second biasing means 6 is disposed on the outer diameter side of the first biasing means 5, but the second biasing means 6 may be disposed on the inner diameter side of the first biasing means 5.

Furthermore, in this embodiment, when the throttle grip G is rotated in the opposite direction, the constant vehicle speed maintenance control of the constant vehicle speed maintenance device (auto cruise device) is stopped (cancelled). It suffices to activate or deactivate a predetermined function provided in the vehicle when rotation in the direction is detected. For example, by rotating the throttle grip G in the opposite direction, authentication may be started in the immobilization system or smart entry system, a starter is activated to start the engine, and an emergency lighting means such as a hazard is activated. Note that the vehicle to which the present invention is applied 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, an ATV or a snowmobile).

The first biasing means and the second biasing means are composed of torsion coil springs, and the coil portions of the first biasing means and the second biasing means overlap in the axial direction of the interlocking member and extend on the coaxial circumference. The interlocking member has an annular first accommodating part that accommodates the first biasing means, and an annular second accommodating part that accommodates the second biasing means. As long as the throttle grip device has a wall portion formed integrally with the interlocking member and the second housing portion is separated, it can be applied to devices with different external shapes or with other functions added. .
