Embodiments of the present invention will be specifically described below with reference to the drawings.
As shown in FIG. 1, the throttle grip device according to this embodiment detects the rotation angle of a throttle grip G attached to a handlebar H of a two-wheeled vehicle, and sends the detection signal to an electronic control device such as an ECU mounted on the two-wheeled vehicle. As shown in FIGS. 2 to 8, it includes a throttle grip G, a case 1, an interlocking member 2, a biasing force applying device 3, a first biasing device 4, and a second biasing device 5. , a rotating member 6, a magnetic sensor 7 (rotation angle detection means), a pressing means 10, and a handle switch case S as a cover member.

Case 1 is disposed inside a handle switch case S attached to the tip side of the handlebar H (base end side of the throttle grip G) of a two-wheeled vehicle (vehicle), and contains various parts that make up this throttle grip device. The interlocking member 2, the biasing force applying means 3, the rotating member 6, etc. are rotatably held therein. Further, reference numeral 9 indicates a lid member for closing the opening side of the case 1.

The throttle grip G extends from the handle switch case S, and can be rotated while being held by the driver.As shown in Figures 1 and 2, the throttle grip G extends from the handle switch case S, and can be rotated in a predetermined direction around the axis from an initial position, as shown in Figures 1 and 2. A forward rotation a and a reverse rotation b in a direction opposite to the predetermined direction are possible. As shown in FIG. 2, the proximal end of the throttle grip G is formed with an engaging portion Ga consisting of a pair of protrusions and a flange portion Gb. The throttle grip G and the interlocking member 2 are connected by engaging with the engaging portion 2a (see FIG. 2, etc.). Further, the flange portion Gb is a portion integrally formed at the base end portion of the throttle grip G over the entire circumferential area.

The interlocking member 2 has an engaged portion 2a that can engage with an engaging portion Ga formed on the throttle grip G, and can rotate in conjunction with forward rotation a and 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 parts 2a, a pair of accommodating parts 2b, a flange 2c, and a gear 2d. Consists of parts.

The engaged portions 2a have concave shapes formed at positions corresponding to the engaging portions Ga of the throttle grip G, and are interlocked when the engaging portions Ga fit into and engaged with the engaged portions 2a. A base end side of a throttle grip G is connected to the member 2. Thereby, the interlocking member 2 can also rotate as the throttle grip G rotates. 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 receiving portion 2b is formed on the other surface. There is. A pair of convex portions 2e each having 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 between the pair of engaged portions 2a, and compression coil springs constituting the second biasing means 5 can be accommodated therein. There is. The flange 2c is formed to protrude in the radial direction over the entire circumference of the interlocking member 2, and a gear 2d is formed over a predetermined range. This gear 2d is capable of meshing with a gear formed on the outer periphery of the rotating member 6, so that the rotating member 6 rotates as the interlocking member 2 rotates.

The rotating member 6 is capable of rotating in conjunction with the interlocking member 2 as described above, and is accommodated in the accommodation recess 1c (see FIG. 9) formed at a predetermined position of the case 1, and is attached to the shaft L (see FIG. 6). , 8). 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 is configured so that 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) consists of a sensor disposed at a position on the extension of the axis L of the rotating member 6, and detects the magnetism generated from the magnet m attached to the rotating member 6. 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 7 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 that uses 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. Note that the magnetic sensor 7 according to this embodiment is formed on a printed circuit board 8 on which a predetermined electric circuit is printed.

Therefore, when the interlocking member 2 rotates in the same direction as the throttle grip G rotates forward a, the rotating member 6 also rotates in conjunction, and the magnet m attached to the rotating member 6 also rotates in the same direction. Rotate by an 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 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 6 also rotates in conjunction, and the magnet m attached to the rotating member 6 also rotates in the same direction by the same angle. Rotate. 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).

Therefore, 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 rotational member 6 is formed, and the inside thereof (in this embodiment, the 2b), and the interlocking member 2 has both the function of transmitting the rotational force of the throttle grip G and the function of accommodating the second urging means 5. has been done.

In addition, the interlocking member 2 according to the present embodiment has a flange 2c in which a gear 2d is formed over a predetermined range, and as shown in FIGS. A contact portion 3c of the means 3 is formed at a position corresponding to the convex portion 2e. Thereby, the stopper 1a and the contact portion 3c can be accommodated within the diameter of the flange 2c of the interlocking member 2, contributing to miniaturization.

The first biasing means 4 is made of a torsion coil spring, and is for biasing the interlocking member 2 toward the initial position when the throttle grip G rotates forward 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 the urging force is transmitted to the throttle grip G, and the throttle grip G is returned to the initial position. There is a force that brings it back.

The second biasing means 5 is composed of a pair of coil springs, and is for biasing 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 the urging force is transmitted to the throttle grip G, and the throttle grip G is returned to the initial position. There is a force that brings it back.

The urging force applying means 3 does not apply the urging force of the second urging means 5 to the interlocking member 2 when the second urging means 5 is attached and the throttle grip G rotates forward a. Only the urging force of the urging means 4 is applied to the interlocking member), and when the throttle grip G rotates in the reverse direction b, the urging force of the second urging means 5 can be applied to the interlocking member 2. Specifically, as shown in FIG. 11, the biasing force applying means 3 includes a pair of protrusions 3a, a pair of spring receivers 3b for receiving one end 5a side of the second biasing means 5, and an abutting part. 3c.

A contact portion 3c that further protrudes in the outer diameter direction is formed on one of the pair of protrusions 3a. In a state where the biasing force applying means 3 is assembled to the interlocking member 2, as shown in FIG. and the end 2eb of the other convex part 2e), and when the interlocking member 2 rotates forward a, the end 2ea of the convex part 2e touches one of the abutting parts 3c, as shown in FIG. By pressing the end surface 3ca, the urging force applying means 3 is rotated together with the interlocking member 2. On the other hand, when the interlocking member 2 rotates in the reverse direction b, as shown in FIG. Since the other end surface 3ca is not pressed during this period, the biasing force applying means 3 is kept in a stopped state while allowing the interlocking member 2 to rotate.

The spring receiver 3b is located within the accommodation portion 2b of the interlocking member 2 when the biasing force applying means 3 is attached to the interlocking member 2, and as shown in FIG. It is capable of receiving one end 5a of the second biasing means 5. The second biasing means 5 is assembled such that one end 5a is supported by the spring receiver 3b and the other end 5b is in contact with the wall surface 10c of the pressing means 10, and the interlocking member 2 and the biasing force applying means 3 rotate together (see FIG. 19), the biasing force by the second biasing means 5 does not act, and when the interlocking member 2 rotates and the biasing force applying means 3 stops (see FIG. 20), the 2 biasing means 5 is compressed to apply biasing force to the interlocking member 2.

Further, the contact portion 3c is formed of a portion integrally formed to protrude in the radial direction of the biasing 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 in the reverse direction b and receives a reaction force due to the urging force of the second urging means 5, the stopped state of the urging force applying means 3 is maintained.

By the way, the first biasing means 4 has one end 4a engaged with an end 2ec (see FIG. 10) of a protrusion 2e formed on the interlocking member 2, and the other end 4b engaged with an engagement formed on the case 1. It is locked in the stop groove 1b (see FIG. 8), and when the interlocking member 2 rotates in the normal direction a and rotates together with the biasing force applying means 3, one end 4a becomes the end 2ec of the convex portion 2e, as shown in FIG. It is configured such that it can apply a biasing force to the interlocking member 2 and the biasing force applying means 3. On the other hand, when the interlocking member 2 rotates in the reverse direction b, as shown in FIG. (between the end portion 2ec) and is not pressed, and the biasing force of the first biasing means 4 is not applied.

As described above, when the second urging means 5 is attached and the throttle grip G rotates forward a, the urging force applying means 3 according to the present embodiment rotates together with the interlocking member 2 to apply the force of the second urging means 5. Formed in the case 1 while allowing rotation of the interlocking member 2 when the throttle grip G rotates in the reverse direction b without applying the urging force to the interlocking member 2 (the urging force of the first urging means 4 is applied). When the stopper 1a and the contact portion 3c come into contact with each other, it is stopped, and the urging force of the second urging means 5 can be applied to the interlocking member 2 (the urging force of the first urging means 4 is not applied). It looks like this. 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 depending on the rotational direction of the throttle grip G.

Here, in this embodiment, when the throttle grip G is in the initial position, the engaging portion Ga of the throttle grip G can be pressed against the engaged portion 2a of the interlocking member 2 by the urging force of the second urging means 5. A pressing means 10 is provided. As shown in FIG. 12, this pressing means 10 contacts a receiving portion 10a and a wall surface 10c that receive the urging force of the second urging means 5, and an engaging portion Ga of the throttle grip G, thereby pressing the second urging means 5. It consists of a shaft-shaped component integrally formed with a contact portion 10b that applies a biasing force of 1 to the engaging portion Ga.

However, as described above, the second biasing means 5 is composed of a coil spring extending in an arc shape at a position between the engaged parts 2a of the interlocking member 2, and the pressing means 10 is Attached to the end of the coil spring. As shown in FIG. 7, the receiving part 10a is assembled in contact with the end (other end) of the second urging means 5, and the urging force of the second urging means 5 is applied to the pressing means 10. It is now possible to do so.

The contact portion 10b has a spherical tip that can come into contact with the engagement portion Ga, and is assembled so as to be inserted through an opening 2g formed in the interlocking member 2. The opening 2g is a hole that communicates between the part where the second biasing means 5 is assembled and the engaged part 2a, and the biasing force of the second biasing means 5 received by the receiving part 10a and the wall surface 10c is applied to the contact part. It is configured such that it can be applied to the engaging portion Ga engaged with the engaged portion 2a via the engagement portion 10b. Note that the pressing means 10 may press the engaging portion Ga against a surface different from the wall surface 2ab.

Further, as shown in FIG. 7, the engaged portion 2a has a concave shape having a wall surface 2aa in which an opening 2g is formed and a wall surface 2ab facing the wall surface 2aa. Since the engaging portion Ga receives the urging force of the second urging means 5 and is pressed against the wall surface 2ab, the throttle grip G in the initial position is prevented from wobbling with respect to the interlocking member 2. In this way, in the pressing means 10 according to the present embodiment, since the engaging portion Ga is pressed against the wall surface 2ab, it is pressed in the rotational direction (forward rotation a side) of the interlocking member 2, thereby preventing rattling. In addition to preventing rattling of the throttle grip G in the initial position, it is possible to position the engaging portion Ga relative to the engaged portion 2a.

Then, when the throttle grip G is rotated forward a from the initial position, the engaging portion Ga presses the wall surface 2ab of the engaged portion 2a, and the interlocking member 2 is rotated in the same direction (forward rotation a), as shown in FIG. direction), and the contact between the contact portion 10b and the engagement portion Ga is maintained. Furthermore, when the throttle G is reversely rotated b from the initial position, the engaging portion Ga moves the pressing means 10 against the urging force of the second urging means 5, and the engaged portion 2a Press the wall surface 2aa of , and rotate the interlocking member 2 in the same direction (the direction of reverse rotation b). At this time, although the contact portion 10a is submerged in the opening 2g, the contact between the contact portion 10a and the engaging portion Ga is maintained.

Furthermore, in this embodiment, the second biasing means 5 having the pressing means 10 is attached to the biasing force applying means 3, and the biasing force applying means 3 is assembled to the interlocking member 2. As a result, a special installation space for the pressing means 10 is not required, and the space between the biasing force applying means 3 and the interlocking member 2 can be effectively utilized, and a dead space is not formed in the case 1. It can prevent you from putting it away.

However, in the present embodiment, two engaging portions Ga of the throttle grip G and two engaged portions 2a of the interlocking member 2 are formed at equal intervals across the rotational direction of the throttle grip G. It is sufficient that a plurality of them are formed at equal intervals over the rotational direction of the throttle grip G, for example, three or more are formed, and the second urging means 5 and the pressing means 10 are respectively provided at positions between the engaged parts 2a. It may also be provided.

Further, 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. 2, the first urging means 4 and the second urging means 5 can be selectively activated depending on the direction of rotation of the throttle grip G. Therefore, the throttle grip G can be rotated more smoothly, and the operability can be further improved.

Here, as shown in FIG. 1, the handle switch case S (cover member) according to the present embodiment is formed with an operation switch M for operating various electrical components of the vehicle, and is fixed to the tip of the handlebar H. The housing includes a first cover member Sa to which the case 1 is fixed, and a second cover member Sb that matches the first cover member Sa to form an accommodation space that covers the case 1. That is, the handle switch case S according to the present embodiment is configured to include a first cover member Sa and a second cover member S2 in a half-split shape, and the interlocking member 2, A case 1 in which a magnetic sensor 7 and the like are arranged is housed therein.

As shown in FIG. 13, the first cover member Sa has an opening Sa1 formed in one side surface through which the base end of the throttle grip G is inserted, and an opening Sa2 formed in the other side surface through which the handlebar H is inserted. has been done. Further, the opening Sa1 formed on one side surface of the first cover member Sa has a cover part α and a notch part β formed at its edge, and is located at a position inside the opening Sa1 (on the opening Sa2 side). A supporting portion Sa3 is formed in a protruding manner so that the protruding end thereof can abut against the outer circumferential surface of the handlebar H of the vehicle and support the handlebar switch case S (cover member).

As shown in FIGS. 13 and 15, the cover portion α of the first cover member Sa is formed at the edge of the opening Sa1 of the first cover member Sa, and the flange portion Gb formed on the throttle grip G (see FIG. 2) It can be covered to prevent it from falling out. Moreover, in addition to the cover part α, a notch part β is formed at an arbitrary position on the edge of the opening Sa1 of the first cover member Sa. That is, a notch β is formed on the edge of the opening Sa1 of the first cover member Sa at an arbitrary position that may interfere with the base end of the throttle grip G when the throttle grip G is engaged. The cover portion α is formed in another region.

As shown in FIG. 14, the second cover member Sb has an opening Sb1 formed in one side surface through which the base end of the throttle grip G is inserted, and an opening Sb2 formed in the other side surface through which the handlebar H is inserted. has been done. Further, the opening Sb1 formed on one side surface of the second cover member Sb has a cover portion γ formed at its edge, and a tip is located at a position inside the opening Sb1 (on the opening Sb2 side) for the vehicle. A support portion Sb3 is formed to project from the outer peripheral surface of the handlebar H and can support the handlebar switch case S (cover member).

As shown in FIGS. 13 and 14, the cover part γ of the second cover member Sb is formed at the edge of the opening Sb1 of the second cover member Sb, and is similar to the cover part α formed in the first cover member Sa. It can cover the flange Gb (see FIG. 2) formed on the throttle grip G to prevent it from coming off. A notch β like the opening Sa1 of the first cover member Sb is not formed at the edge of the opening Sb1 of the second cover member Sb.

Next, a method for assembling the throttle grip G will be explained.
First, as shown in FIG. 16, after fixing the case 1 in which the interlocking member 2, the magnetic sensor 7, etc. are assembled to a predetermined position in the first cover member Sa with screws, etc., the throttle grip G is slightly tilted. Then, the base end of the throttle grip G is inserted into the opening Sa1 while avoiding interference by the notch β. Then, as shown in FIG. 17, in the process of setting the throttle grip G in a horizontal state, the engaging portion Ga of the throttle grip G is engaged with the engaged portion 2a of the interlocking member 2 in the case 1.

In this way, when the throttle grip G is engaged with the interlocking member 2, the flange part Gb is interposed between the support part Sa3 and the cover part α, and the cover part α covers the flange part Gb and comes out. It will be stopped. Thereafter, by aligning the second cover member Sb with the first cover member Sa and fixing it with screws or the like, the cover portions (α, γ) of the first cover member Sa and the second cover member Sb are connected to the flange portion Gb. are covered, and the flange Gb is located between the cover portions (α, γ) and the support portions Sa3 and Sb3, and the rotation of the flange Gb is guided. In this way, it is possible to obtain a throttle grip device in which the case 1 is housed in the handle switch case S and the throttle grip G is assembled.

According to the present embodiment, the first cover member Sa and the second cover member Sb are each formed with an opening (Sa1, Sb1) through which the base end portion of the throttle grip G is inserted, and the opening (Sa1, Sb1) is formed in the first cover member Sa and the second cover member Sb. Since a cover part (α, γ) that covers the flange part Gb formed on the throttle grip G and prevents it from coming off is formed on the edge of the throttle grip G, the shape and size of the base end of the throttle grip G, and the interlocking Any cover portion (α, γ) can be formed depending on the engagement position with respect to the member 2, the distance between the opening (Sa1, Sb1) and the case 1, etc. It is possible to suppress backlash occurring in the throttle grip G while maintaining workability during engagement.

Furthermore, by forming the cover portions (α, γ), it is possible to avoid a large gap from being formed between the edges of the openings (Sa1, Sb1) and the base end of the throttle grip G, so that foreign objects can be prevented from entering from the outside. In addition, it is possible to prevent the interior of the handle switch case S from being seen through the gap, and the design can be improved. Furthermore, the cover portions (α, γ) can improve the strength when the throttle grip G is pulled in the axial direction.

In addition, in addition to the cover part α, a cutout part β is formed at an arbitrary predetermined position on the edge of the opening Sa1 of the first cover member Sa, so that when the throttle grip G is engaged with the interlocking member 2, The notch β can prevent the base end of the throttle grip G from interfering with the edge of the opening Sa1, and improve workability when engaging the throttle grip G with the interlocking member 2.

Moreover, since the flange Gb according to the present embodiment is formed over the entire circumferential area at the base end of the throttle grip G, there is some gap between the edge of the opening Sa1 and the throttle grip G (especially, Even if a gap due to the notch β occurs, the flange Gb can prevent foreign matter from entering. Note that the flange Gb is not limited to being formed over the entire circumferential area, and may be such that the flange Gb is not formed in a part of the base end of the throttle grip G in the circumferential direction.

Further, the first cover member Sa and the second cover member Sb can support the handle switch case S (cover member) by coming into contact with the outer peripheral surface of the handlebar H of the vehicle at a position inside the openings (Sa1, Sb1). Since the supporting parts (Sa3, Sb3) are formed to protrude and the flange part Gb is interposed between the supporting parts (Sa3, Sb3) and the covering parts (α, γ), rotation of the throttle grip G is prevented. At this time, the flange portion Gb can be guided between the support portions (Sa3, Sb3) and the cover portions (α, γ), and the throttle grip G can be rotated stably.

Furthermore, since the cover member is composed of a handle switch case S in which an operation switch M for operating various electrical components of the vehicle is formed, the cover member accommodates a case 1 having an interlocking member 2 and a magnetic sensor 7 (rotation angle detection means). It can have both functions as a handlebar switch and a function as a handlebar switch. Note that the handle switch case S is not limited to the handle switch case S in which the operation switch M is formed as in this embodiment, but may be a cover member in which the operation switch M is not formed.

However, according to the present embodiment, since the pressing means 10 is provided which can press the engaging part Ga against the engaged part 2a by the urging force of the second urging means 5 when the throttle grip G is in the initial position, The second biasing means 5 can serve as a biasing device that generates a biasing force when the throttle grip G rotates in reverse, and a biasing device that generates a biasing force to prevent backlash, thereby increasing the number of biasing devices. It is possible to suppress backlash between the throttle grip G and the interlocking member 2 without causing any movement.

Although the present embodiment has been described above, the present invention is not limited to this. For example, the throttle grip G is not limited to a case where the throttle grip G can rotate forwardly and reversely as in the present embodiment, but can only rotate in one direction. It may be equipped with a throttle grip G that can be used, or it may be equipped with a different type of urging means from the first urging means 4 and the second urging means 5, or it may be equipped with a different type of urging means from the first urging means 4 and the second urging means 5, or only one of the urging means. It may be equipped with one.

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 cover member and the second cover member each have an opening through which the base end of the throttle grip is inserted, and the edge of the opening can cover a flange formed on the throttle grip to prevent it from coming off. If it is a throttle grip device in which a cover portion is formed, and a cutout portion is formed at an arbitrary predetermined position on the edge of the opening of the first cover member in addition to the cover portion, the external shape may be different. Alternatively, it can also be applied to devices with other functions added.
