Description

  The present invention relates to a throttle grip device in which the engine of a vehicle is controlled based on the rotational operation of a throttle grip.

  In a recent two-wheeled vehicle, a throttle grip device configured to detect a rotation angle of a throttle grip by a throttle opening degree sensor such as a potentiometer and send the detected value as an electric signal to an electronic control device or the like mounted on the two-wheeled vehicle. Has become widespread. Then, the electronic control unit performs a predetermined calculation based on the detection signal, and based on the calculation result, the ignition timing of the engine and the opening and closing of the intake valve or the throttle valve are controlled.

  In such a throttle grip device, the rotational angle of the throttle grip is detected by the throttle opening sensor, so that a universally used operation cable is unnecessary to transmit the rotational operation of the throttle grip to the engine side. Be done. Therefore, at the time of the rotation operation of the throttle grip, the sliding resistance generated by the inner tube sliding against the outer tube constituting the operation cable is eliminated conventionally, and the force transmitted to the driver at the time of the rotation operation of the throttle grip There is a problem that it becomes a sense of incongruity because it becomes only the force to return to the initial position by the return spring.

  In order to solve such a problem, as a first prior art, as disclosed in Patent Document 1, provided with a friction plate for applying a frictional force in a direction opposite to the rotational direction when the throttle grip is operated for rotation. It is proposed that the rotational load be obtained by the frictional force generated by the friction plate. According to such a conventional throttle grip device, the throttle wire can be eliminated, and the driver can operate the throttle grip without feeling discomfort.

  On the other hand, when the rotational load of the throttle grip is generated by the frictional force of the friction plate as in the first prior art, the resistance force generated by the friction plate is constant regardless of the rotational angle of the throttle grip. It is difficult to respond to the user's request, for example, when you want to generate a larger rotation load when the rotation angle of the is large, or when you want to generate a larger rotation load when the rotation angle of the throttle grip is small. There was a case.

  Therefore, as a second prior art, as disclosed in Patent Document 2, one is proposed that is coated over a predetermined range on the friction surface of the friction plate to change the frictional resistance in the coated range. There is. According to such a throttle grip device, since the rotational load can be changed according to the rotational angle of the throttle grip, the rotational load generated at the time of the rotational operation of the throttle grip can be changed according to the user's request.

Japanese Patent Application Laid-Open No. 2003-252274 JP, 2010-280304, A

  However, in the second prior art, since it is necessary to partially change the frictional resistance of the friction plate, it is difficult to accurately correspond the range in which the frictional resistance is changed to the rotation angle of the throttle grip. There was a risk of becoming Also, in order to cause friction resistance by causing the friction plate fixed to the case to abut against the friction plate that rotates in conjunction with the throttle grip, two friction plates are used to partially change the friction resistance. In each of them, it is necessary to form precisely the part which changes the frictional resistance.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The throttle grip device according to the present embodiment detects the rotation angle of the throttle grip G attached to the handlebar H of a two-wheeled vehicle, as shown in FIG. As shown in FIGS. 2 to 12, the throttle grip G, the case 1, the interlocking member 2, the biasing force applying means 3, the torsion coil spring 4, the coil spring 5, and the rotating member 6. And a magnetic sensor 7 (rotational angle detection means) and a resistance means 10.

  The case 1 is disposed in the switch case S (see FIG. 1) mounted on the tip end side (base end side of the throttle grip G) of the handlebar H of a two-wheeled vehicle (vehicle). While accommodating the various components to comprise, it hold | maintains the interlocking member 2, the biasing force provision means 3, the rotation member 6 grade | etc., Rotatably. In addition, the code | symbol M in FIG. 1 has shown the switch knob formed in switch case S, and can operate the desired electrical component mounted in the two-wheeled vehicle by operating the desired switch knob M. There is. Further, reference numeral 9 denotes a lid member for closing the opening side of the case 1.

  The throttle grip G is extended from the switch case S and can be rotated while being gripped by the driver. As shown in FIGS. 1 and 2, the throttle grip G is positive in a predetermined direction about the axis from the initial position. The rotation a and the reverse rotation b in the direction opposite to the predetermined direction are possible. On the base end side of the throttle grip G, engaging portions Ga (see FIG. 2) formed of a pair of projecting portions are formed, and these engaging portions Ga are engaged portions 2a of the interlocking member 2 (FIG. 2). The throttle grip G and the interlocking member 2 are connected by engaging (4 to 4 etc.).

  The interlocking member 2 has an engaged portion 2a that can engage with the engaging portion Ga formed on the throttle grip G, and can rotate in conjunction with the forward rotation a and the reverse rotation b of the throttle grip G It is. Specifically, as shown in FIGS. 7 and 8, the interlocking member 2 according to the present embodiment has a pair of engaged portions 2a, a pair of accommodating portions 2b, a flange 2c, and a gear 2d. It comprises an annular member. In particular, a sliding surface n, which will be described in detail later, is formed on the flange 2c according to the present embodiment.

  The engaged portion 2a has a concave shape respectively formed at a position corresponding to the engaging portion Ga of the throttle grip G, and interlocking is performed in a state where the engaging portion Ga is fitted into and engaged with the engaged portion 2a. The base end side of the throttle grip G is connected to the member 2. Thus, the interlocking member 2 can also be rotated with the rotation of the throttle grip G. 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 as shown in FIG. 4), and the other surface is The accommodating part 2b is formed.

  The housing portion 2b is formed of a pair of groove shapes formed in an arc shape at a position between the pair of engaged portions 2a, in each of which a compression coil spring constituting the coil spring 5 can be accommodated. . Further, a flange 2c is formed on the interlocking member 2 in the circumferential direction, and a gear 2d is formed on a part of the flange 2c over a predetermined range. The gear 2d is assembled in a state of meshing with a gear formed on the outer periphery of the rotating member 6, as shown in FIGS. 12 to 14, so that the rotating member 6 rotates as the interlocking member 2 rotates. ing.

  The rotating member 6 can rotate in conjunction with the interlocking member 2 as described above, and is accommodated at a predetermined position of the case 1 and rotatable about the axis L (see FIGS. 2 and 12 to 14) It is assumed. Thus, when the interlocking member 2 is rotated, as shown in FIGS. 12 to 14, the rotating member 6 is rotated at a rotation angle corresponding to the rotation angle. A magnet m is attached to the rotating member 6, and the direction of the magnetic field of the magnet m is changed as the rotating member 6 rotates.

  As shown in FIG. 6, the magnetic sensor 7 (rotational angle detection means) comprises a sensor disposed at a position on the extension of the axis L of the rotary member 6, and the magnetic sensor 7 produces magnetic from the magnet m attached to the rotary member 6. The rotation angle of the throttle grip G can be detected by detecting the change of Specifically, the magnetic sensor 7 can obtain an output voltage according to a change in the magnetic field (change in magnetic flux density) of the magnet m, and is, for example, a Hall element (specifically, a magnetic sensor utilizing a Hall effect) Is constituted by 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. The magnetic sensor 7 according to the present embodiment is formed on the printed circuit board 8 on which a predetermined electric circuit is printed.

  Thus, when the interlocking member 2 rotates in the same direction as the throttle grip G rotates forward a, the rotating member 6 also interlocks and rotates, and the magnet m attached to the rotating member 6 also rotates the interlocking member 2 and It rotates by an angle according to the gear ratio of the rotating member 6. Thereby, the magnetic field changes according to the rotation angle, so that an output voltage corresponding to the rotation angle can be obtained, and the rotation angle of the interlocking member 2 (that is, the rotation angle of the throttle grip G) is detected based on the output voltage. It is possible to do. The rotation angle of the throttle grip G thus detected is transmitted as an electrical signal to an ECU (engine control unit) mounted on a two-wheeled vehicle, and the rotation angle of the throttle grip G is transmitted according to the transmitted rotation angle. The engine can be controlled.

  On the other hand, when the interlocking member rotates in the same direction as the throttle grip G rotates in the reverse direction b, the rotary member 6 also interlocks and rotates, and the magnet m attached to the rotary member 6 is also the interlocking member 2 and the rotary member It rotates by an angle according to the gear ratio of 6. As a result, since the magnetic field changes according to the rotation angle, an output voltage corresponding to the rotation angle can be obtained, and the reverse rotation b of the throttle grip G can be detected.

  As described above, when the reverse rotation b of the throttle grip G is detected, it is possible to activate or deactivate a predetermined function of the two-wheeled vehicle. In this embodiment, the present invention is applied to a two-wheeled vehicle equipped with a constant vehicle speed holding device (auto cruise device) for keeping the traveling speed constant, and reverse rotation b of the throttle grip G (forward rotation a of fully opening the throttle from the initial position The rotation control in the direction opposite to the direction (1) is configured to be able to stop (cancel) the holding control of the constant vehicle speed.

  Thus, 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 rotary member 6 is formed, and the inside (in the present embodiment, the housing The coil spring 5 is accommodated in the portion 2b, and the interlocking member 2 has a function of transmitting the rotational force of the throttle grip G and a function of accommodating the coil spring 5 in combination.

  The torsion coil spring 4 is a return spring for biasing the interlocking member 2 rotated in the same direction 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 is rotated against the biasing force of the torsion coil spring 4, and the biasing force is transmitted to the throttle grip G to force the throttle grip G back to the initial position. It works.

  The coil springs 5 are arranged in a circular arc, and are used to urge 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 reversely rotated b, the interlocking member 2 rotates against the urging force of the coil spring 5, so that the urging force is transmitted to the throttle grip G and the force for returning the throttle grip G to the initial position is It works.

  The biasing force application means 3 does not apply the biasing force of the coil spring 5 to the interlocking member 2 when the coil spring 5 is attached and the throttle grip G rotates forward a (at this time, only the biasing force of the torsion coil spring 4 The biasing force of the coil spring 5 can be applied to the interlocking member 2 when the throttle grip G is reversely rotated b). Specifically, as shown in FIG. 9, the biasing force applying means 3 includes a pair of projecting portions 3a, a pair of spring receivers 3b for receiving one end 5a of the coil spring 5, and an abutting portion 3c. It consists of an annular member which it has.

  An abutting portion 3c further projecting in the outer diameter direction is formed on one of the pair of projecting portions 3a. Then, as shown in FIG. 12, when the interlocking member 2 rotates forward in the state where the urging force applying means 3 is assembled to the interlocking member 2, as shown in FIG. Is rotated (the biasing member 3 is rotated by the interlocking member 2). On the other hand, when the interlocking member 2 is reversely rotated b, as shown in FIG. 14, the biasing member 3 is stopped while the interlocking member 2 is rotating (a state in which the interlocking member 2 is not rotated).

  The spring receiver 3b is located in the housing portion 2b of the interlocking member 2 in a state where the biasing force application means 3 is attached to the interlocking member 2, and the one end 5a side of the coil spring 5 accommodated in the housing portion 2b. Can be received. The coil spring 5 is assembled such that one end is supported by the spring receiver 3b and the other end is in contact with the edge wall of the housing 2b, and both the interlocking member 2 and the biasing force applying means 3 rotate. (See FIG. 13), the biasing force of the coil spring 5 does not act, and when the biasing force application means 3 is stopped while the interlocking member 2 rotates (see FIG. 14), the coil spring 5 is compressed and attached. A force is applied to the interlocking member 2.

  Furthermore, the contact portion 3c is formed of a portion integrally formed so as to protrude integrally in the radial direction of the biasing force applying means 3, and the stopper (not shown) formed on the case 1 when the interlocking member 2 is reversely rotated b. Can come in contact with the Thereby, even if the interlocking member 2 is reversely rotated b and receives a reaction force by the urging force of the coil spring 5, the stopped state of the urging force applying means 3 is held.

  By the way, one end 4a of the torsion coil spring 4 is locked to a predetermined portion of the interlocking member 2, and the other end 4b is locked to a predetermined portion of the case 1, and the interlocking member 2 rotates forward a When it rotates with the applying means 3, the one end 4 a is pressed, and an urging force can be applied to the interlocking member 2 and the urging force applying means 3. On the other hand, when the interlocking member 2 is reversely rotated b, one end 4a of the torsion coil spring 4 is not pressed, and the biasing force of the torsion coil spring 4 is not applied.

  Thus, the coil spring 5 is attached to the biasing force application means 3 according to the present embodiment, and when the throttle grip G rotates forward a, the biasing force of the coil spring 5 is rotated with the interlocking member 2 When the throttle grip G rotates in the reverse direction b without applying to 2 (the biasing force of the torsion coil spring 4 is applied), the stopper formed on the case 1 and the contact portion 3c while allowing the rotation of the interlocking member 2 Is stopped by the contact, and the biasing force of the coil spring 5 can be applied to the interlocking member 2 (the biasing force of the torsion coil spring 4 is not applied). Thus, the biasing force of the torsion coil spring 4 or the coil spring 5 can be appropriately and reliably applied to the interlocking member 2 in accordance with the rotational direction of the throttle grip G.

  The resistance means 10 can generate a resistance force when the throttle grip G rotates to generate a rotational load, and in the present embodiment, as shown in FIG. 15, the resistance means 10 is formed along the circumferential direction of the interlocking member 2 The sliding member 11 assembled in a contact state with respect to the sliding surface n and an urging force are applied to the sliding member 11 to cause the sliding surface n to press, and the rotation of the interlocking member 2 It comprises and the biasing means 12 which can produce a sliding resistance in connection with it. The sliding surface n according to the present embodiment is formed on a flange 2 c integrally formed on the interlocking member 2, and has a size capable of sliding the sliding member 11. Further, as shown in FIGS. 15 to 18, the biasing means 12 according to the present embodiment is constituted by a pair of coil springs which can press the sliding member 11 against the sliding surface n by the biasing force.

  As shown in FIGS. 10 and 11, the sliding member 11 is formed with a surface 11a which can be in contact with and slid on the sliding surface n, and is assembled by inserting the biasing means 12 (coil spring). It is configured to have a pair of projecting portions 11 b to be obtained. Further, as shown in FIG. 5, an accommodation hole 1a is formed at a predetermined position of the case 1, and the urging means 12 is accommodated in the accommodation hole 1a, and the urging means 12 is protruded with respect to the urging means 12 After the sliding member 11 is assembled by inserting the portion 11b, when the surface 11a of the sliding member 11 is brought into contact with the sliding surface n, the biasing means 12 compresses and the biasing force on the sliding member 11 Can be given.

  Since the sliding member 11 is pressed against the sliding surface n under the urging force of the urging means 12, the interlocking member 2 rotates and the surface 11a slides along the sliding surface n. If it moves, the sliding resistance according to energizing force will arise. As a result, when the throttle grip G is rotated and the interlocking member 2 is rotated, a sliding resistance is generated by the sliding member 11, and a rotational load such as that provided with a conventional throttle wire is generated.

  Here, in the present embodiment, the rotational load generated at the time of rotation of the throttle grip G can be arbitrarily changed by arbitrarily changing the biasing force of the biasing means 12 according to the rotation angle of the interlocking member 2 ing. That is, as shown in FIGS. 15-18, the sliding surface n according to the present embodiment has an inclined surface for changing the compression dimension of the biasing means 12, and the sliding member 11 slides on the inclined surface. Thus, the biasing force of the biasing means 12 can be changed.

  More specifically, the inclined surface according to the present embodiment is formed over substantially the entire area of the sliding surface n (that is, the sliding surface n is inclined by a predetermined angle in the sliding direction of the sliding member 11) And the biasing means 12 is accommodated in the accommodation hole 1a of the case 1 and the mounting position h is constant, the sliding member 11 is In the process of sliding, the compression size of the biasing means 12 can be gradually changed, and the biasing force of the biasing means 12 can be changed continuously.

  Furthermore, the surface 11 a of the sliding member 11 according to the present embodiment is formed of a surface inclined by substantially the same angle as the inclination angle of the sliding surface n. Then, in a state where the sliding member 11 is assembled in a state in which the sliding member 11 abuts on the sliding surface n, the substantially whole area of the surface 11a of the sliding member 11 is slidable while conforming to the sliding surface n. Thus, when the throttle grip G is rotated, the sliding member n can slide smoothly on the inclined sliding surface n, and an arbitrary rotational load can be favorably generated.

  For example, when the throttle grip G is rotated in the forward direction a, the interlocking member 2 (see FIG. 16) in the initial position rotates in the same direction, and along the sliding surface n where the sliding member 11 forms the inclined surface. It will slide. At this time, as shown in FIG. 17, the sliding member 11 slides on the inclined surface in the upward direction, so that the biasing means 12 is compressed and the compression dimension becomes gradually larger. The force (pressure on the sliding surface n) increases continuously. As a result, in the process of rotating the throttle grip G forwardly, the sliding resistance generated by the sliding member 11 gradually increases, and the rotational load of the throttle grip G gradually increases.

  On the other hand, when the throttle grip G rotated forward is returned to the initial position, the sliding member 11 slides downward along the sliding surface n forming the inclined surface, so that the biasing means 12 is extended and compressed. The size gradually decreases, and the biasing force (pressure on the sliding surface n) applied to the sliding member 11 is continuously reduced. As a result, in the process of returning the throttle grip G, which has been positively rotated a, to the initial position, the sliding resistance generated by the sliding member 11 becomes gradually smaller, and the rotational load of the throttle grip becomes gradually smaller.

  Further, when the throttle grip G is reversely rotated b, the interlocking member 2 (see FIG. 16) in the initial position rotates in the same direction, thereby along the sliding surface n where the sliding member 11 forms an inclined surface. It will slide (sliding in the opposite direction to the case where the throttle grip G is rotated a). At this time, as shown in FIG. 18, since the sliding member 11 slides in the downward direction on the inclined surface, the biasing means 12 is extended and the compression dimension becomes gradually smaller, and the biasing force applied to the sliding member 11 (Pressing force on the sliding surface n) decreases continuously. Thus, in the process of rotating the throttle grip G in the reverse direction b, the sliding resistance generated by the sliding member 11 gradually increases, and the rotational load of the throttle grip G gradually increases.

  On the contrary, when the throttle grip G which has been reversely rotated a is returned to the initial position, the sliding member 11 slides upward along the sliding surface n forming the inclined surface, so the biasing means 12 compresses The compression dimension is gradually increased, and the biasing force (pressure on the sliding surface n) applied to the sliding member 11 is continuously increased. Thus, in the process of returning the reversely rotated throttle grip G to the initial position, the sliding resistance produced by the sliding member 11 gradually increases, and the rotational load of the throttle grip gradually increases.

  However, the inclination angle of the sliding surface n forming the inclined surface can be set arbitrarily according to the preference of the user. The sliding surface n may be divided into a plurality of sections, and the sections may be inclined to be inclined surfaces, and the inclination angles of the inclined surfaces in the sections may be made different. Furthermore, the sliding surface n is divided into a plurality of sections, and in each section, the surface is inclined to be an inclined surface, and different surface treatment is performed in each section to make the sliding resistance different. Good.

  According to the present embodiment, the resistance means 10 includes the sliding member 11 assembled in a contact state with the sliding surface n formed along the circumferential direction of the interlocking member 2 and the sliding member 11. A biasing force is applied to press against the sliding surface n, and biasing means 12 capable of causing a sliding resistance as the interlocking member 2 rotates is provided, and the rotation angle of the interlocking member 2 Since the rotational load generated at the time of rotation of the throttle grip G can be arbitrarily changed by changing the urging force of the urging means 12 arbitrarily, the rotational load generated at the time of the rotational operation of the throttle grip G can be arbitrary according to the user's request. And can be accurately changed.

  In addition, the sliding surface n according to the present embodiment has an inclined surface for changing the compression dimension of the urging unit 12, and the urging force of the urging unit 12 when the sliding member 11 slides on the inclined surface. Can be changed, so that the rotational load generated when the throttle grip G rotates can be changed with a simple configuration. Furthermore, the inclined surface according to the present embodiment is formed over substantially the entire area of the sliding surface n, and the biasing force of the biasing means 12 is continuously changed in the process in which the sliding member 11 slides on the inclined surface. Therefore, the rotational load generated when the throttle grip G rotates can be continuously changed.

  Furthermore, since the sliding surface n according to the present embodiment is formed on the flange 2 c integrally formed on the interlocking member 2, the sliding of the sliding member 11 along with the rotation of the throttle grip G and the interlocking member 2. The sliding on the surface n can be made to follow well, and the rotational load generated at the time of the rotational operation of the throttle grip G can be changed more accurately according to the user's request. The sliding surface n may be formed in a portion different from the flange 2 c of the interlocking member 2.

  In addition, the throttle grip G and the interlocking member 2 can be rotated in the predetermined direction from the initial position in the normal direction a and in the reverse direction b in the opposite direction to the predetermined direction. Since it is possible to control the engine of the vehicle according to the rotation angle of the throttle grip G, and when the throttle grip G and the interlock member 2 reversely rotate, a predetermined function of the vehicle may be activated or deactivated. Different operations can be performed according to the direction of rotation of.

  The present embodiment has been described above, but the present invention is not limited thereto. For example, the biasing means 12 may be made of another versatile elastic body (a spring of another form such as a torsion spring or a plate spring, or a resin And rubber etc.). Further, in the present embodiment, although the present invention is applied to a throttle grip capable of both forward rotation a and reverse rotation b rotation operations, it is applied to a throttle grip capable of only forward rotation a. It is also good. Furthermore, the magnetic sensor 7 may be replaced by another sensor (such as a sensor that does not use magnetism) that can detect the rotational angle of the throttle grip G.

  Furthermore, in the present embodiment, when the throttle grip G is reversely rotated, holding control of the constant vehicle speed holding device (auto cruise device) is stopped (canceled). It is sufficient to detect the reverse rotation, as long as it activates or deactivates a predetermined function of the vehicle. For example, when the throttle grip G rotates in the reverse direction, authentication start in an immobilizer system or smart entry system, activation of a starter for starting an engine, activation of emergency lighting means such as a hazard may be performed. The vehicle to which the present invention is applied is not limited to a two-wheeled vehicle as in the present embodiment, but may be applied to another vehicle (for example, an ATV, a snowmobile, etc.) having a handlebar H.

  The resistance means applies a biasing force to the sliding member assembled in a state of contact with the sliding surface formed along the circumferential direction of the interlocking member, and applies a biasing force to the sliding surface. The throttle grip includes a biasing means capable of causing a sliding resistance as the interlocking member rotates while causing the interlocking member to rotate, and optionally changing the biasing force of the biasing means according to the rotation angle of the interlocking member. The present invention can be applied to a throttle grip device capable of arbitrarily changing the rotational load generated at the time of rotation of the motor, to which the external shape is different or to which another function is added.
