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 a rotation angle of a throttle grip G attached to a handlebar pipe H of a two-wheeled vehicle and outputs a detection signal to an electronic control unit such as an ECU mounted on the two-wheeled vehicle. As shown in FIGS. 1 to 5, it is for transmitting, and includes an interlocking member 1, a magnetic sensor 2 (rotation angle detecting means), a return spring 3, a holding member 4, and a case C. Has been done.

The interlocking member 1 is capable of rotating together with the rotating operation of the throttle grip G of the vehicle, and as shown in FIGS. 8 and 9, is made of a substantially cylindrical resin molded product having one end face M1 and the other end face M2. The fitted portion 1a into which the fitting portion Ga (see FIG. 3) of the throttle grip G can be fitted, the mounting recess 1b for mounting the magnet m, and the locking for locking the one end 3a of the return spring 3. A portion 1c and a stopper portion 1d protruding at a predetermined position are formed.

In this embodiment, the fitted portion 1a, the mounting recess 1b and the stopper portion 1d are formed on one end surface M1 of the interlocking member 1, and the locking portion 1c is formed on the other end surface M2. .. As shown in FIG. 10, the magnet m has a helical surface ma that bends in an arc shape and continuously changes in height, and when mounted in the mounting recess 1b, the helical surface ma is outward. To face.

The case C is fixed to the tip end side (base end side of the throttle grip G) of the handle pipe H of the two-wheeled vehicle (vehicle), holds the interlocking member 1 rotatably, and holds the magnetic sensor 2 (rotation angle detecting means). ) And a return spring 3 are attached. The case C according to the present embodiment is configured by assembling a first case Ca and a second case Cb, of which the first case Ca includes wall portions Ca1 and Ca2 that hold the interlocking member 1 as shown in FIG. A locking portion Ca3 that locks the other end 3b of the return spring 3, an interference portion Ca4 that can interfere with the stopper portion 1d of the interlocking member 1, and a storage portion S1 that can store the magnetic sensor 2 are formed. ..

One wall surface of the wall portion Ca1 is a sliding surface N1 in the axial direction β of the interlocking member 1, and the bottom surface between the wall portions Ca1 and Ca2 is a sliding surface in the circumferential direction of the interlocking member 1. It is set to N2. That is, when the interlocking member 1 is attached between the wall portion Ca1 and the wall portion Ca2, one end surface M1 of the interlocking member 1 comes into contact with the sliding surface N1 of the wall portion Ca1 and can slide. There is. In addition, a pair of ribs r1 extending in the circumferential direction of the interlocking member 1 are formed on the sliding surface N2, and the interlocking member 1 is configured to slide and rotate on these ribs r1. A screw hole n1 is formed at a predetermined position of the first case Ca.

On the other hand, when the throttle grip G is rotated from the initial position toward the opposite side, the stopper portion 1d of the interlocking member 1 is set to interfere with the interference portion Ca4 of the first case Ca, and the throttle grip G is set. It is possible to prevent the rotation operation from the initial position toward the opposite side.

As shown in FIG. 3, the magnetic sensor 2 (rotation angle detecting means) is composed of a sensor arranged at a predetermined position (accommodation portion S1) of the first case Ca and detects a change in magnetism generated by the magnet m. Thus, the rotation angle of the interlocking member 1 can be detected, and the rotation angle of the throttle grip G can be detected. Specifically, the magnetic sensor 2 can obtain an output voltage according to a change in the magnetic field of the magnet m (change in magnetic flux density). For example, a Hall element (specifically, a Hall element that is a magnetic sensor utilizing the Hall effect). 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. When the magnet m rotates as the throttle grip G rotates and the interlocking member 1 rotates, the distance between the helical surface ma and the magnetic sensor 2 changes, and the magnetic field changes. ..

As a result, the magnetic field changes depending on the rotation angle of the interlocking member 1, 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 based on the output voltage. ) Is detected. The rotation angle of the throttle grip G detected in this way is transmitted as an electric signal to an ECU (engine control unit) mounted on the two-wheeled vehicle, and the rotation angle of the vehicle is changed according to the transmitted rotation angle of the throttle grip G. The engine can be controlled. In addition, reference numeral h in the drawing indicates a wiring extended from the magnetic sensor 2, and the detection signal is transmitted to the vehicle side via the wiring h.

The return spring 3 is composed of a coil spring that urges the throttle grip G and the interlocking member 1 toward the initial position in the rotational direction α when the throttle grip G is rotated, and as shown in FIG. It has one end 3a locked to the stopper 1c, the other end 3b locked to the locking part Ca3 of the case C, and a coil part 3c located between the one end 3a and the other end 3b. There is.

In this way, the return spring 3 has one end 3a attached to the interlocking member 1 and the other end 3b attached to the case C, and is attached to the return spring 3 when the throttle grip G is rotated. Since the interlocking member 2 rotates against the force, the urging force is transmitted to the throttle grip G, and a force for returning the throttle grip G and the interlocking member 1 to the initial position acts.

As shown in FIG. 7, the holding member 4 has a sliding surface N3 in the circumferential direction of the interlocking member 1, and is made of a resin component that rotatably holds the interlocking member 1, and the sliding surface N3. A pair of ribs r2 extending in the rotation direction of the interlocking member 1 are formed on the. The holding member 4 has a screw hole n2 formed at a position corresponding to the screw hole n1 formed in the case C. As shown in FIG. 4, when the interlocking member 1 is held, the screw holes n1 and n2 are screwed. The holding member 4 can be fixed to the case C (first case Ca) by inserting and screwing in b.

Then, the interlocking member 1 is attached between the wall portion Ca1 and the wall portion Ca2 in the first case Ca, and the holding member 5 is attached so as to cover the interlocking member 1 so that the entire circumferential surface of the interlocking member 1 slides. It is covered with N1 and the sliding surface N3 to enable sliding in the rotation direction α. Further, since the interlocking member 1 slides on the rib r1 of the sliding surface N1 and the rib r2 of the sliding surface N3 during rotation, the contact surface with respect to the interlocking member 1 can be reduced.

Further, the holding member 4 according to the present embodiment, as shown in FIG. 7, the holding portion 4a that holds the return spring 3, the edge portion (upper edge portion) of the one end surface M1 of the interlocking member 1, and the other end surface thereof. A guide portion 4b capable of guiding rotation is integrally formed so as to cover the edge portion (upper edge portion) of M2. Thus, the holding member 4 holds the interlocking member 1 rotatably with the first case Ca, holds the return spring 3 at an appropriate position by the holding portion 4a, and holds it by the guide portion 4b. The rotation of the interlocking member 1 can be guided (preventing the interlocking member 1 from being displaced in the axial direction β).

Here, the return spring 3 according to the present embodiment is configured to bias the interlocking member 1 in the axial direction β in addition to the rotation direction α. Specifically, as shown in FIG. 11, the return spring 3 according to the present embodiment is a coil portion 3c having a gap between adjacent windings, and as shown in FIGS. In the state of being assembled in the first case Ca, the gap between the windings of the coil portion 3c is compressed in the direction in which the gap becomes smaller, and the interlocking member 1 is biased in the axial direction β.

As a result, the interlocking member 1 is assembled with the one end surface M1 pressed against the sliding surface N1 by the urging force of the return spring 3 in the axial direction β. Further, in the return spring 3 according to the present embodiment, as shown in FIG. 12, the end portion 3ca of the coil portion 3c falls within a predetermined range (a predetermined range extending in the circumferential direction of the end portion 3ca) by the biasing force in the axial direction β. The other end surface M2 of the interlocking member 1 is in contact therewith.

Further, in the throttle grip device according to the present embodiment, as shown in FIGS. 3 and 12, the magnetic sensor 2 (rotation angle detecting means) is arranged on one end face M1 side of the interlocking member 1, and the interlocking member is provided. The return spring 3 is disposed on the other end surface M2 side of the No. 1. That is, the magnetic sensor 2 is provided on one side (the right side in FIG. 12 and the one end face M1 side) across the interlocking member 1, and the other side (the left side in the figure and the other end face M2 side) is provided. Return springs 3 are provided respectively.

According to the above-described embodiment, the return spring 3 urges the interlocking member 1 in the axial direction β in addition to the rotation direction α, so that the interlocking member 1 is pressed against the axial direction β while being elastic. Can be absorbed, the rotation of the interlocking member 1 can be stably performed, and the operability of the throttle grip G can be maintained. In particular, in the present embodiment, the first case Ca is formed with the sliding surface N1 that can be slid in contact with the one end surface M1 of the interlocking member 1, and the return spring 3 applies the biasing force in the axial direction β. Since the one end surface M1 is pressed against the sliding surface N1, the play of the interlocking member 1 can be absorbed.

Further, since the magnetic sensor 2 (rotation angle detecting means) is disposed on one end surface M1 side of the interlocking member 1 (that is, the direction in which the interlocking member 1 is pressed against the sliding surface N1), the interlocking member 1 The distance between the one end face M1 and the magnetic sensor 2 (rotation angle detecting means) can be kept constant, and the detection accuracy of the rotation angle of the throttle grip G by the magnetic sensor 2 can be improved.

Further, in the return spring 3 according to the present embodiment, the end portion 3ca of the coil portion 3c comes into contact with the interlocking member 1 over a predetermined range due to the biasing force in the axial direction β, so that the return spring 3 is biased in the axial direction β. The force can be applied to the interlocking member 1 substantially evenly, and the rotation of the interlocking member 1 can be further stabilized. That is, since the return spring 3 is biased in the axial direction β, the end portion 3ca of the coil portion 3c is pressed against the other end surface M2 which is the contact surface with the interlocking member 1, and the contact state is maintained over a predetermined range. Is done.

Further, the interlocking member 1 has a sliding surface N3 in the circumferential direction, and further includes a resin holding member 4 that rotatably holds the interlocking member 1, and the sliding surface N3 of the holding member 4 includes: Since the rib r2 extending in the rotation direction of the interlocking member 1 is formed, the area of the sliding surface in the circumferential direction of the interlocking member 1 can be reduced, and the interlocking member 1 can be smoothly rotated.

In addition, the holding member 4 according to the present embodiment includes a holding portion 4a that holds the return spring 3, an edge portion of one end surface M1 of the interlocking member 1, and an edge portion of the other end surface (either one edge portion). The guide portion 4b capable of guiding the rotation is integrally formed so that the holding member 4 holds the interlocking member 1, the function of holding the return spring 3, and the interlocking member. It can also have a function of guiding the rotation of 1.

Furthermore, since the interlocking member 1 according to the present embodiment is provided separately from the throttle grip G, it is possible to prevent an excessive load applied to the throttle grip G from being transmitted to the interlocking member 1. The replacement of the interlocking member 1 or the throttle grip G can be facilitated.

In addition, according to the present embodiment, the magnetic sensor 2 (rotation angle detecting means) is arranged on one end surface M1 side of the interlocking member 1, and the return spring 3 is arranged on the other end surface M2 side of the interlocking member 1. Since the arrangement is provided, the arrangement positions of the return spring 3 and the magnetic sensor 2 with respect to the interlocking member 1 can be arbitrarily set, and the degree of freedom in the layout of the components and the assembling property can be improved. That is, since the magnetic sensor 2 and the return spring 3 are disposed on the one end face M1 side and the other end face M2 side of the interlocking member 1, respectively, they are located at appropriate positions (positions facing the magnet m in the magnetic sensor 2, The return spring 3 can be arranged at a position where the interlocking member 1 can be surely given a biasing force in the circumferential direction.

Further, in the one in which the magnetic sensor 2 is disposed on one end surface M1 side of the interlocking member 1 and the return spring 3 is disposed on the other end surface M2 side of the interlocking member 1, the return spring 3 rotates In addition to the direction α, the interlocking member 1 is biased in the axial direction β and pressed toward the sliding surface N1 in the disposing direction of the magnetic sensor 2, so that the one end surface M1 of the interlocking member 1 and the magnetic sensor 2 are separated from each other. It is possible to keep the distance dimension constant, improve the detection accuracy of the rotation angle of the throttle grip G by the magnetic sensor 2, and press one end surface M1 of the interlocking member 1 against the sliding surface N1 to cause backlash. Can be absorbed.
