Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The throttle operating device according to the present embodiment is attached to a vehicle such as an ATV or a four-wheel buggy and can operate the accelerator during traveling. As shown in FIGS. 1 to 5, the operating means 1 and the locking means 2 are It includes an interlocking member 3, a case member 4, a return spring 5, a resistance means 6, a rotating member 8, a rotation angle detecting means 10 (detecting means), and a case C.

Further, as shown in the figure, the operating means 1 of the throttle operating device according to the present embodiment is attached to the vicinity of the base end side of the grip grip G on the handlebar H of the vehicle and is adjacent to the case C. It is installed in a rotatable state. The case C houses parts such as an interlocking member 3, a case member 4, a return spring 5, a resistance means 6, a rotating member 8, and a rotation angle detecting means 10.

The operating means 1 is attached in the vicinity of the grip grip G of the vehicle, and is composed of a substantially annular member capable of operating the accelerator by rotating the shaft L to drive the vehicle. As shown in FIGS. It has a book protrusion (one protrusion 1a and the other protrusion 1b). In such an operating means 1, one rotation operation α and the other rotation operation β can be performed around the axis L, the vehicle can be advanced by one rotation operation α, and the vehicle can be moved by the other rotation operation β. It is said that it can be retreated.

More specifically, since one protruding portion 1a and the other protruding portion 1b are formed so as to be separated from each other by a desired dimension with respect to the circumferential direction of the operating means 1, the driver holds the grip grip G. One of the rotation operations α is enabled by applying a finger (for example, the thumb) to one of the protruding portions 1a and pressing it forward, and the driver holds the finger (for example, the index finger) of the hand holding the grip grip G. The rotation operation β of the other is possible by hitting the protruding portion 1b on the other and pulling the operation backward.

Further, in the operation means 1 according to the present embodiment, the lock means 2 is attached to a predetermined portion. The locking means 2 can regulate the rotation operation β of the other while allowing the rotation operation α of one, and can arbitrarily release the regulation of the rotation operation β of the other. What is the rotation operation of the operation means 1? It can be operated independently (sliding operation in the direction of the arrow in FIG. 2). That is, the locking means 2 is configured to be in a lock position that regulates the other rotation operation β in the normal state, and is in an unlock position that allows the other rotation operation β by the slide operation.

Specifically, as shown in FIG. 9, in the locking means 2, the operation portion 2a and the protrusion 2b are integrally formed, and the pin p and the spring s1 are attached to predetermined portions, respectively. The operation unit 2a is composed of a portion that can be operated from the lock position to the unlock position by the driver touching the finger to slide the lock means 2, and the protrusion 2b has a slope surface 2ba on one side and a slope surface 2ba on the other side. It is composed of convex portions having wall surfaces 2bb formed on the sides.

Then, when the locking means 2 is assembled to the operating means 1, as shown in FIG. 6, the operating unit 2a is in a state of facing the outside, and the sliding operation can be easily performed. Further, when the locking means 2 is assembled to the operating means 1, as shown in FIG. 7, the pin p is inserted into the elongated hole m formed in the operating means 1, and the locking means 2 can be guided in the operating direction. At the same time, the locking means 2 is held at the locked position by the urging force of the spring s1.

On the other hand, in the case C, as shown in FIG. 8, a protrusion Ca having a wall surface Ca1 on one side and a slope surface Ca2 on the other side is integrally formed, and the operating means 1 is located adjacent to the case C. As shown in FIG. 3, the protrusion Ca of the case C and the protrusion 2b of the locking means 2 face each other with respect to the operating direction of the operating means 1. As a result, when the locking means 2 is in the locked position (non-operating state), the wall surface Ca1 of the protrusion Ca and the wall surface 2bb of the protrusion 2b come into contact with each other to regulate the other rotation operation β of the operating means 1. it can. When the locking means 2 is in the locked position, when the operating means 1 is rotated by one of the rotating operations α, the protrusion Ca of the case C and the protrusion 2b of the locking means 2 do not interfere with each other. It will be tolerated.

Here, when the locking means 2 is slid from the locked position to the unlocked position, the protruding portion 2b of the locking means 2 is separated from the protruding portion Ca of the case C. Therefore, when the operating means 1 is rotated by the other, the protrusions Interference between the portion Ca and the protrusion 2b is avoided, and the other rotation operation β is allowed. Further, after the locking means 2 is slid to the unlocked position and the other rotation operation β is performed, the locking means 2 returns to the locked position by the urging force of the spring s1 in the process of returning the operating means 1 to the initial position. Even if the lock means 2 interferes with the slope surface Ca2 of the protrusion Ca and the slope surface 2ba of the protrusion 2b, the locking means 2 escapes in the slide operation direction against the urging force of the spring s1, so that the operation means 1 is initially used. It is said that it can be moved to the position.

The interlocking member 3 is housed in the case member 4 and can rotate in accordance with one rotation operation α and the other rotation operation β of the operation means 1. As shown in FIG. 10, the interlocking member 3 of the operation means 1 A fitted portion 3a that can be fitted with a fitting portion 1c (see FIG. 6), a locked portion 3b (see FIG. 14) in which both ends of the return spring 5 are locked, and a gear g2 of the rotating member 8. It is configured to have a gear g1 that meshes with the gear g1. Then, since the fitted portion 3a of the operating means 1 is fitted to the fitting portion 1c of the operating means 1, when one rotation operation α or the other rotation operation β with respect to the operating means 1 is performed, the interlocking member 3 Is designed to rotate against the urging force of the return spring 5.

As shown in FIG. 12, the case member 4 rotatably holds the interlocking member 3 and the rotating member 8, respectively, and as shown in FIG. 13, the opening surface is closed by the cover member 7. ing. As shown in FIG. 11, the case member 4 has a boss portion 4a in which a storage space 4aa is formed, a recess 4b to which the rotating member 8 is attached, and a rotation center of the rotating member 8 attached to the recess 4b. It is configured to have a boss portion 4c formed in a protruding manner.

As shown in FIG. 5, the accommodating space 4aa of the boss portion 4a accommodates the spring s2 and the resistance means 6 having the friction material 6a, and resists the interlocking member 3 by the urging force of the spring s2. It is configured to be able to press the friction material 6a of the means 6. As a result, when the interlocking member 3 rotates with one rotation operation α and the other rotation operation β of the operating means 1, frictional resistance can be generated between the interlocking member 3 and the operating means 1.

The return spring 5 urges the operating means 1 and the interlocking member 3 toward the initial position when the operating means 1 is rotated. In the present embodiment, the operating means 1 is rotated by one of the rotating operations α and the other. It is composed of a common torsion coil spring that urges the operating means 1 toward the initial position when the rotating operation β is performed. As shown in FIG. 14, the return spring 5 is assembled by locking both ends thereof to the locked portion 3b of the interlocking member 3, and one of the rotation operations α or the other with respect to the operating means 1. When the rotation operation β is performed, one end of the return spring 5 is rotated and moves together with the locked portion 3b, and the other end interferes with the boss portion 4c and is held without being rotated. Therefore, the urging force is generated.

As shown in FIGS. 12 and 14, the rotating member 8 has a gear g2 that meshes with the gear g1 of the interlocking member 3 on the outer peripheral surface, and can rotate in conjunction with the interlocking member 3, and serves as a magnetic generating member. A magnet 9 is attached. The magnet 9 is fixed to the rotating member 8 and can generate magnetism, so that the rotating member 8 and the magnet 9 can rotate integrally about the rotation axis R. The rotating member 8 is urged in the rotational direction by the torsion spring s3 (see FIG. 5) to prevent backlash between the gear g1 and the gear g2.

The rotation angle detecting means 10 (detecting means) includes a magnetic sensor capable of detecting the magnetic change of the magnet 9 and detecting the rotation direction and the rotation angle of the rotating member 8, and as shown in FIG. 5, the present embodiment. Is formed on the substrate 11 on which a predetermined electric circuit is printed. Then, when one rotation operation α or the other rotation operation β is performed on the operating means 1, the interlocking member 3 and the rotating member 8 rotate according to the rotation direction and the rotation angle. Therefore, the rotation direction and the rotation angle thereof. Can be detected by the rotation angle detecting means 10. Thereby, the rotation direction and the rotation operation angle of the operation means 1 can be detected based on the detection value detected by the rotation angle detection means 10 to drive the vehicle (forward or backward).

According to the present embodiment, the operating means 1 is capable of one rotation operation α and the other rotation operation β, and is capable of moving the vehicle forward by one rotation operation α, and the vehicle is enabled by the other rotation operation β. Since it is possible to reverse the vehicle, the driver can be surely recognized the accelerator operation when the vehicle is moving forward and the accelerator operation when the vehicle is moving backward, and erroneous operation can be prevented. Further, the operating means 1 according to the present embodiment has at least two protruding portions (one protruding portion 1a and the other protruding portion 1b), and one protruding portion 1a is pressed forward. Since one rotation operation α is possible and the other rotation operation β is possible by pulling the other protrusion 1b backward, the forward and backward operations are sensuously operated (that is, forward movement). It can be operated forward when it is operated, and operated backward when it is retracted), and the operability can be improved.

Further, since it is provided with the locking means 2 capable of restricting the other rotation operation β while allowing one rotation operation α and arbitrarily releasing the regulation of the other rotation operation β, there is no intention to move the vehicle backward. Nevertheless, it is possible to prevent the operating means 1 from accidentally performing the other rotation operation β, and it is possible to improve safety. Further, when the operating means 1 is subjected to one rotation operation α and the other rotation operation β, a common return spring 5 for urging the operating means 1 toward the initial position is provided, so that the operation means 1 can be used for one rotation operation. The number of parts can be reduced as compared with the one provided with both the return spring and the return spring for the other rotation operation. By using the common return spring 5, it is possible to easily equalize the operating force required for one rotation operation α when moving forward and the operating force required for the other rotation operation β when moving backward.

Further, since the resistance means 6 capable of causing frictional resistance in association with one rotation operation α and the other rotation operation β of the operation means 1 is provided, the operability of both the one rotation operation α and the other rotation operation β is provided. Can be improved. Further, the interlocking member 3 which has an interlocking member 3 which rotates and has a gear g1 in accordance with one rotation operation α and the other rotation operation β of the operating means 1 and a gear g2 which meshes with the gear g1 of the interlocking member 3 A rotating member 8 that can rotate in conjunction with the rotation member 8, a magnet 9 (magnetic generating member) that is fixed to the rotating member 8 and can generate magnetism, and a rotation direction and rotation of the rotating member 8 by detecting a magnetic change of the magnet 9. The vehicle is provided with a rotation angle detecting means 10 (detecting means) capable of detecting an angle, and detects the rotation operation direction and the rotation operation angle of the operation means 1 based on the detection value of the rotation angle detection means 10 (detection means). It is not necessary to switch gears or the like to move the vehicle forward or backward, and the operability can be further improved.

Although the present embodiment has been described above, the present invention is not limited to this, and for example, the rotation operation direction and the rotation operation angle of the operation means 1 may be directly detected to move the vehicle forward or backward. 1 and the interlocking member 3 may have an integral structure. Further, the locking means 2 may not be provided, or the operating means 1 may have a further protruding portion formed in addition to the one protruding portion 1a and the other protruding portion 1b.
