Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The throttle operating device according to the first embodiment is a handle provided by a vehicle such as an ATV or buggy, a ship such as a PWC (personal watercraft), or a vehicle such as a snow vehicle (in this embodiment, a vehicle such as an ATV or buggy).

The fixing member 1 is fixed to the handlebar H and rotatably supports the throttle lever 2, and is fixed in the vicinity of the grip grip formed at the tip of the handlebar H of the vehicle. As shown in FIG. 4, the fixing member 1 has an opening at the upper side to form an accommodating recess, and a sandwiching member 4 is attached to the fixing member 1, and the handlebar H is sandwiched by the sandwiching member 4. It is said that it can be fixed.

Further, the fixing member 1 is formed with a pair of restricting portions 1a-1a formed at a predetermined position on the outside thereof at a predetermined position apart from each other by a predetermined dimension, and a sealing member 9 is formed on the bottom surface of the accommodating recess formed inside. The mounting groove 1b for fitting and positioning (see FIG. 3), the through hole 1c through which the shaft member L is inserted to allow the rotation operation of the throttle lever 1, and the other end Sb of the return spring S (see FIGS. 6 to 8). ) Are each formed as a locking portion 1d.

The throttle lever 2 is attached so as to extend from the lower part of the fixing member 1 so that the driver can rotate the throttle lever 2 while gripping the grip grip of the vehicle. As shown in FIG. 3, the throttle lever 2 is a shaft member L. Is linked to. The shaft member L rotates around the shaft in response to the rotation operation of the throttle lever 2, and the rotating member 5 is fixed to the tip of the shaft member L by a mounting screw Nb and a washer W. As shown in FIG. 7, the throttle lever 2 has a protruding portion 2a protruding laterally, and the protruding portion 2a is between the pair of regulating portions 1a-1a in a state of being assembled to the fixing member 1. It is configured to be located in. As a result, the rotation angles of the throttle lever L and the shaft member L are restricted to a predetermined range.

As shown in FIGS. 6 and 7, the rotating member 5 is made rotatable in response to the rotation operation of the throttle lever 2, and as shown in FIG. 9, the resistance applying means 7 and the coil spring 9 (FIG. 8).

There is. However, since one end Sa of the return spring S is locked to the locking portion 5c of the rotating member 5 and the other end Sb is locked to the locking portion 1d of the fixing member 1 and assembled, the throttle lever 1 is rotated. When the shaft member L and the rotating member 5 are rotated by operation, they are urged toward the initial position by the return spring S.

Further, as shown in FIGS. 6 to 8, the rotating member 5 is attached with the mounting member 6 by a pair of mounting screws n.

By pressing the magnet M, the magnet M is prevented from coming off.

In this way, the throttle lever 2, the shaft member L, the rotating member 5, the mounting member 6, the magnet M, and the return spring S are assembled to form the integrated component Y as shown in FIG. Therefore, by rotating the throttle lever 2, the integral component Y rotates with respect to the fixing member 1, and the integral component Y is urged toward the initial position by the return spring S, so that the throttle is throttled. By loosening the operating force on the lever 2, the throttle lever 2 returns to the initial position.

As shown in FIGS. 1 to 3, the cover member 3 is fixed by the mounting screw Na while covering the upper opening of the fixing member 1, and is opened laterally as shown in FIG. It is composed of a molded part having a housing recess 3a and a lower surface 3b facing the magnet M in a state of being attached to the fixing member 1.

The sliding member K is made of an annular metal member, and is configured so that the resistance applying means 7, which will be described later, can slide. The inner region of the sliding member K on the lower surface 3b of the cover member 3 constitutes a contact surface 3ba that can rotate while the magnet M is in contact with the cover member 3, so that the magnet M can be rotated stably. ..

Further, the cover member 3 can be sealed by pressing the seal member 9 in a state of being attached to the fixing member 1. That is, when the cover member 3 is attached to the fixing member 1, as shown in FIG. 3, the pressing surface 3bb formed in the peripheral region of the lower surface 3b of the cover member 3 presses the seal member 9, and the fixing member 1 The inside (internal space where the rotating member 5 and the like are located) can be sealed.

The detection sensor 11 can detect the rotation operation angle of the throttle lever 2. In the present embodiment, the detection sensor 11 includes an angle sensor that detects a magnetic change of the magnet M and detects the rotation angle. That is, when the magnet M rotates with the rotation operation of the throttle lever 2, the detection sensor 11 can detect the magnetic change of the magnet M due to the rotation and detect the rotation operation angle of the throttle lever 2.

Then, when the detection sensor 11 detects the rotation operation angle of the throttle lever 2, the detection signal is transmitted to the ECU (engine control unit) provided in the vehicle via the wiring h connected to the substrate 10, and the throttle is concerned. The engine (drive source) of the vehicle is controlled based on the rotation operation angle of the lever 2.

Here, the throttle operating device according to the present embodiment includes a resistance applying means 7 capable of causing friction during the rotation operation of the throttle lever 2 to apply resistance. As shown in FIGS. 6 to 8, the resistance applying means 7 is made of a resin member attached to the attachment portion 5a of the rotating member 5 and urged upward by the coil spring 8, and the throttle lever 2 is provided. When the rotating member 5 rotates with the rotation operation of the above, the rotating member 5 can rotate together with the rotating member 5.

Specifically, as shown in FIG. 12, the resistance applying means 7 is integrally formed with a protruding end surface 7a, a boss portion 7b, and a protruding portion 7c. The tip surface 7a is formed of a flat surface formed at the tip of the resistance applying means 7, and is composed of a surface capable of sliding on the sliding surface Ka of the sliding member K formed on the cover member 3. The boss portion 7b has a protruding shape formed on the lower surface of the resistance applying means 7, and is capable of holding the coil spring 8. Further, the protruding portion 7c is composed of a pair of bulging portions formed on the side surface of the resistance applying means 7, and corresponds to the holding groove 5aa (see FIGS. 8 and 9) formed in the mounting portion 5a of the rotating member 5. As a result, the resistance applying means 7 can be positioned and the displacement of the resistance applying means 7 can be guided.

However, the resistance applying means 7 is urged by the coil spring 8 toward the sliding surface Ka of the sliding member K, and as shown in FIG. 3, the tip surface 7a is in contact with the sliding surface Ka. At the same time, the rotating member 5 rotates with the rotation operation of the throttle lever 2, and when the rotating member 5 rotates together with the rotating member 5, the tip surface 7a in contact with the position A slides to the position B as shown in FIG. It is configured to move. That is, since the sliding surface Ka formed on the cover member 3 is composed of the surface of the sliding member K formed along the movement locus of the resistance applying means 7, the tip surface 7a is formed from the position A to the position B. In the process of sliding, friction can be generated to impart resistance.

According to the present embodiment, since the resistance applying means 7 capable of causing friction during the rotation operation of the throttle lever 2 to apply the resistance is provided, the operation of the throttle lever is transmitted to the engine side via the operation wire. Compared with the conventional one, the operation feeling can be made similar, and the operability at the time of the rotation operation of the throttle lever 2 can be improved.

Further, since the detection sensor 11 is attached to a position corresponding to the magnet M and can detect the rotation operation angle of the throttle lever 2 based on the magnetic change of the magnet M that rotates according to the throttle lever 2, the throttle lever 2 It is possible to accurately detect the rotation operation angle of. In particular, the detection sensor 11 according to the present embodiment can detect the rotation operation angle of the throttle lever 2 based on the magnetic change of the magnet M that rotates according to the throttle lever 2, and corresponds to the magnet M in the cover member 3. Since the cover member 3 has a function of covering the opening of the fixing member 1 and a function of attaching the detection sensor 11, the portion where the detection sensor 11 is attached (particularly, the accommodating recess 3a) is waterproofed. Countermeasures can be easily taken.

Further, in the present embodiment, the rotating member 5 which is connected to the shaft member L and rotates according to the rotation operation of the throttle lever 2 is provided, and the resistance applying means 7 is attached to the rotating member 5. Therefore, the resistance force can be smoothly applied by the resistance force applying means 7 by the rotation of the rotating member 5, and the throttle operating device can be miniaturized. In particular, the resistance applying means 7 according to the present embodiment has a sliding surface Ka attached to the rotating member 5 and formed on the cover member 3 (in this embodiment, the sliding surface Ka of the sliding member K). Since it is configured to slide and generate friction, the cover member 3 has a function of covering the opening of the fixing member 1 and a function of attaching the detection sensor 11, and also holds the sliding surface Ka of the resistance applying means 7. Can have the function of

Further, in the present embodiment, a cover member 3 that covers the opening of the fixing member 1 is provided, and a sliding surface Ka is formed on the cover member 3, and the sliding surface Ka is a movement of the resistance applying means 7. Since it is composed of the surface of the sliding member K formed along the locus, the cover member 3 has a function of covering the opening of the fixing member 1 and a function of holding the sliding surface Ka of the resistance applying means 7. At the same time, the resistance applying means 7 can be reliably slid along the sliding surface Ka. Further, the resistance applying means 7 according to the present embodiment is made of a resin member urged toward the sliding surface Ka by a coil spring 8 (a urging means) attached to the rotating member 5, and is also slid. Since the moving member K is made of a metal member insert-molded into the cover member 3, the frictional force generated by the resistance applying means 7 can be stably generated.

Further, according to the present embodiment, the seal member 9 for sealing the inside of the fixing member 1 is provided, and the cover member 3 can be sealed by pressing the sealing member 9 while being attached to the fixing member 1. Therefore, in addition to the function of covering the opening of the fixing member 1 and the function of attaching the detection sensor 11, the cover member 3 can have a function of holding the seal by the seal member 9.

In addition, since the detection sensor 11 according to the present embodiment is attached to the cover member 3 at a position corresponding to the magnet M, the cover member 3 has a function of covering the opening of the fixing member 1 and a function of attaching the detection sensor 11. It is possible to reduce the size of the throttle operating device and the number of parts.

Next, the throttle operation device according to the second embodiment of the present invention will be described.
Similar to the first embodiment, the throttle operating device according to the second embodiment is a vehicle such as an ATV or buggy, a ship such as a PWC (personal watercraft), or a vehicle such as a snow vehicle (in this embodiment, the ATV or buggy). The engine (drive source) of the vehicle is fixed to the handle bar of the vehicle, and the engine (drive source) of the vehicle can be controlled. As shown in FIGS. The throttle lever 2, the cover member 3, the rotating member 5, the resistance applying means 7, the detection sensor 11, the return spring S, the sliding member K, and the operating load generating means 12. Has been done. In addition, except for the parts described separately in the present embodiment, the same reference numerals are given to the parts common to the first embodiment, and detailed description thereof will be omitted.

The fixing member 1 is fixed to the handlebar H and rotatably supports the throttle lever 2, and is fixed in the vicinity of the grip grip formed at the tip of the handlebar H of the vehicle. As shown in FIGS. 16 and 17, the fixing member 1 has an upper opening to form an accommodating recess inside, and a sandwiching member 4 is attached to the fixing member 1, and the handlebar H is sandwiched by the sandwiching member 4. It is said that it can be fixed.

Further, on the bottom surface of the accommodating recess formed inside the fixing member 1, a mounting groove 1b for fitting and positioning the seal member 9 (see FIG. 15) and a shaft member L are inserted to rotate the throttle lever 1. A through hole 1c that allows operation, a first fixing portion 1d that locks and fixes one end Sa (see FIGS. 21 to 23) of the return spring S, and the other end Sb of the return spring S (see FIGS. 21 to 23). ) Is locked and fixed, and a third fixing portion 1f that locks and fixes the pressed portion 13b (see FIGS. 25 to 27) of the operating load generating means 12 is formed. There is.

Here, in the throttle operating device according to the present embodiment, as in the first embodiment, the throttle lever 2 can be rotated in the forward direction α and the reverse direction β with respect to the fixing member 1, and the detection sensor. 11 is attached to the position corresponding to the magnet M in the cover member 3, and it is possible to detect the rotation operation of the throttle lever 2 in the forward direction α and the rotation operation in the reverse direction β, respectively, by the rotation operation in the forward direction α. The engine (drive source) of the vehicle can be controlled, and a predetermined device mounted on the vehicle can be operated or the operation of the device can be stopped by a rotation operation in the reverse direction β.

Further, one end Sa of the return spring S can be locked to the first locking portion 5c of the rotating member 5 (see FIGS. 19 and 23) and the first fixing portion 1d of the fixing member 1 (see FIGS. 16 and 17). The other end Sb is assembled so that it can be locked to the second locking portion 5d (see FIGS. 20 and 23) of the rotating member 5 and the second fixing portion 1e (see FIGS. 16 and 17) of the fixing member 1. Has been done. Then, when the throttle lever 2 is rotated in the positive direction α and the rotating member 5 rotates in the same direction, one end Sa of the return spring S is locked to the first locking portion 5c and the rotating member 5 is rotated. Since the other end Sb is locked and fixed to the second fixing portion 1e of the fixing member 1 while rotating, an urging force is applied in the direction of returning the throttle lever 2 to the initial position.

Further, when the rotating member 5 is rotated in the same direction by rotating the throttle lever 2 in the reverse direction β, the other end Sb of the return spring S is locked to the second locking portion 5d and responds to the rotation of the rotating member 5. One end of Sa is locked and fixed to the first fixing portion 1d of the fixing member 1 while rotating, and an urging force is applied in the direction of returning the throttle lever 2 to the initial position.

However, the throttle operating device according to the present embodiment is operated when a predetermined operating load is generated when the throttle lever 2 is rotated in the reverse direction β and when the throttle lever 2 is rotated in the forward direction α. The throttle lever 2 is provided with an operating load generating means 12 that does not generate a load, whereby the operating load in the reverse direction β is set to be larger than the operating load in the forward direction α.

As shown in FIGS. 21, 22, and 26, the operating load generating means 12 is attached to the mounting groove 6e formed in the mounting member 6 and can rotate together with the rotating member 5 to generate an operating load. As shown in FIGS. 24 and 25, the displacement means 13 that is displaced according to the rotational operation of the throttle lever 2 with respect to the reverse direction β, and the urging means 14 that generates an urging force according to the displacement of the displacement means 13. It is equipped.

The displacement means 13 is composed of a member extending in an arc shape along the rotation direction of the mounting member 6, and includes a housing recess 13a for accommodating the urging means 14, a pressed portion 13b formed to protrude laterally, and the pressed portion 13b. It is configured to have a protruding portion 13c formed so as to protrude upward. The urging means 14 is composed of a coil spring extending in an arc shape, and is housed in a storage recess 13a formed in an arc shape. Further, as shown in FIG. 26, the mounting member 6 is formed with an arc-shaped insertion groove 6f, and the displacement means 13 to which the urging means 14 is mounted is mounted on the mounting groove portion 6e of the mounting member 6. The protrusion 13c is inserted into the insertion groove 6f formed in the mounting member 6.

Then, when the throttle lever 2 is operated in the reverse direction β, the integral component Y rotates in the same direction, and the mounting member 6 rotates in the reverse direction β, as shown in FIG. 17, the pressed portion 13b of the displacement means 13 Is in contact with the third fixed portion 1f, so that the displacement means 13 is relatively displaced with respect to the mounting member 6 (see the two-dot chain line in FIG. 26), and the urging means 14 is compressed. As a result, when the throttle lever 2 is rotated in the reverse direction β, a predetermined operating load can be generated by the urging force of the urging means 14. When the displacement means 13 is displaced with respect to the mounting member 6, the protruding portion 13c of the displacement means 13 moves along the insertion groove 6f, so that stable displacement can be performed.

On the other hand, when the throttle lever 2 is operated in the positive direction α, the integral component Y rotates in the same direction, and the mounting member 6 rotates in the positive direction α, the displacement means 13 and the urging means 14 follow the mounting member 6. Since it rotates, the mounting member 6 is not displaced (relatively displaced), and the urging means 14 is not compressed. As a result, when the throttle lever 2 is rotated in the positive direction α, the urging force of the urging means 14 is not generated, and the operation load by the operating load generating means 12 is not generated. When the throttle lever 2 is operated in the positive direction α, the operating load by the operating load generating means 12 is not generated, but the operating load due to the urging force of the return spring S is generated as described above.

Further, in the present embodiment, the throttle lever 2 is provided with a return spring S that urges the throttle lever 2 to the initial position when the throttle lever 2 is rotated in the forward direction α and the reverse direction β. Is rotated in the reverse direction β, both the urging force by the return spring S and the operating load by the operating load generating means 12 are generated at the same time. That is, when the throttle lever 2 is rotated in the reverse direction β, the urging force by the return spring S and the operating load by the operating load generating means 12 are added, and the combined force is applied as the operating load.

However, the resistance applying means 7 is urged by the coil spring 8 toward the sliding surface Ka of the sliding member K so that the tip surface 7a is in contact with the sliding surface Ka and the throttle lever 2 is in contact with the sliding surface Ka. The rotating member 5 rotates with the rotation operation, and rotates together with the rotating member 5. Then, as shown in FIG. 27, when the throttle lever 2 is rotated in the forward direction α, the tip surface 7a in contact with the position A slides to the position B, and the throttle lever 2 moves in the reverse direction β. When the rotation operation is performed, the tip 7a in contact with the position A can slide to the position C. That is, since the sliding surface Ka formed on the cover member 3 is composed of the surface of the sliding member K formed along the movement locus of the resistance applying means 7, the position of A to the position of B or the position of C. In the process of sliding the tip surface 7a up to, friction can be generated to impart resistance.

According to the present embodiment, the throttle lever 2 can be rotated in the forward direction α and the reverse direction β, and the operating load in the reverse direction β is set to be larger than the operating load in the forward direction α. When operating the lever 2 in the forward direction α, it is possible to prevent the lever 2 from being accidentally operated in the reverse direction β. In particular, the throttle lever 2 according to the present embodiment can control the drive source (engine) of the vehicle by the rotation operation in the forward direction α, and a predetermined device mounted on the vehicle by the rotation operation in the reverse direction β. Since the operation or the operation of the device can be stopped, the rotation operation of the throttle lever 2 can smoothly operate the other devices of the vehicle in addition to the throttle control.

Further, according to the present embodiment, when the throttle lever 2 is rotated in the reverse direction β, a predetermined operating load is generated, and when the throttle lever 2 is rotated in the forward direction α, an operating load is generated. Since the operating load generating means 12 for preventing the operation load is provided, the operating load in the reverse direction β in the throttle lever 2 can be set to be larger than the operating load in the forward direction α.

Further, since the operating load generating means 12 can rotate together with the rotating member 5 to generate an operating load, the operating load can be reliably generated when the throttle lever 2 is operated with respect to the reverse direction β. Further, the operating load generating means 12 according to the present embodiment is a displacement means 13 that is displaced according to the rotation operation of the throttle lever 2 with respect to the reverse direction β, and an additional force that generates an urging force according to the displacement of the displacement means 13. Since the force means 14 is provided, the operating load can be reliably and smoothly generated when the throttle lever 2 is operated with respect to the reverse direction β.

In addition, according to the present embodiment, when the throttle lever 2 is rotated in the forward direction α and the reverse direction β, the throttle lever 2 is provided with a return spring S for urging the throttle lever 2 to the initial position, and the throttle lever 2 is provided. Is rotated in the reverse direction β to generate an urging force by the return spring S and an operating load by the operating load generating means 12, so that it is generated by the operating load generating means 12 when the throttle lever 2 is operated with respect to the reverse direction β. It is possible to generate a relatively large drag force (combined operating load) by adding the operating load to be caused and the urging force by the return spring S.

Although the present embodiment has been described above, the present invention is not limited to this, and for example, the resistance applying means 7 may be attached to a component (mounting member 6 or the like) different from the rotating member 5, and may be a resin. May be of other different materials. Further, although the sliding member K is made of a metal member, it is made of another material as long as it can generate friction by sliding the resistance applying means 7 and impart resistance. It may be attached to the cover member 3 by a method other than insert molding such as screwing. In addition, a separate sliding member K may not be provided, and for example, the lower surface 3b of the cover member 3 may be processed to form a sliding surface of the urging force applying means 7.

If the purpose is the same as that of the present invention, it can be applied to those having different appearance shapes or those to which other functions are added.
