Embodiments of the present invention will be specifically described below with reference to the drawings.
The throttle grip device 1 according to the present embodiment is for detecting the rotation angle of a throttle grip G attached to a handlebar H of a two-wheeled vehicle and sending the signal to an electronic control device such as an ECU mounted on the two-wheeled vehicle. As shown in 1 to 7, it has a throttle grip G, an interlocking member 2, a case member 3, a rotation angle detection means 6, an output terminal 7, a magnetic shielding member 8, and a frictional resistance imparting means 11. It is composed of

The throttle grip G is attached to the tip of the handlebar of the vehicle, and can be rotated while being held by the driver, and has an interlocking member 2 (throttle pipe) fixed inside. The interlocking member 2 is integrated with the throttle grip G by, for example, insert molding or adhesive, and can rotate in conjunction with the throttle grip G.

Further, as shown in FIG. 7, the interlocking member 2 is a cylindrical member having a mounting portion 2a for mounting the magnet M, a sliding surface 2b formed on the flange surface, and a locking groove 2c. At the same time, a pipe lock 5 is locked and fixed inside with a locking groove 2c. Thereby, when the throttle grip G is rotated, the interlocking member 2 and the pipe lock 5 can be rotated integrally.

The case member 3 is fixed to the base end side of the throttle grip G on the handlebar H, and as shown in FIGS. The storage recess 3b is formed in the housing recess 3b, and the protrusion 3c is formed to protrude in the axial direction. A fixing ring R is attached to the case member 3, and the case member 3 can be fixed to the handlebar H by tightening the fixing ring R with a screw or the like.

Further, a return spring 4 made of a torsion coil spring is attached between the case member 3 and the interlocking member 2. The return spring 4 is assembled with one end locked to the case member 3 and the other end locked to the interlocking member 2, and when the throttle grip G is rotated, the return spring 4 returns to the initial position. It is designed to be biased toward the target.

The frictional resistance imparting means 11 generates frictional resistance when the interlocking member 2 rotates, and as shown in FIG. A coil spring 11b that biases the friction portion 11a toward the sliding surface 2b, a screw portion 11c that is assembled by passing through the coil spring 11b, and a fixed portion 11d that is in contact with the base end side of the coil spring 11b. It is composed of:

By rotating the screw portion 11c and displacing the fixing portion 11d in the axial direction of the screw portion 11c, the compression dimension of the coil spring 11b can be arbitrarily adjusted. The urging force can be adjusted arbitrarily. As a result, in the process of rotating the throttle grip G, the friction portion 11a slides on the sliding surface 2b, and an arbitrary frictional resistance force is applied.

Here, a connector member B to which a rotation angle detecting means 6 and an output terminal 7 are attached is fixed to the mounting portion 3a of the case member 3 by press fitting. That is, the connector member B is accommodated and press-fitted in the accommodation recess 3b formed in the attachment part 3a, and in the fixed state, as shown in FIG. The rotation angle detection means 6 is disposed in a region where changes in magnetism can be detected.

The rotation angle detecting means 6 is capable of generating a detection signal according to the rotation angle of the interlocking member 2, and in this embodiment is composed of a magnetic sensor capable of detecting changes in the magnetism of the magnet M. Specifically, the rotation angle detection means 6 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 is, for example, a Hall element (specifically, a magnetic sensor using the Hall effect). Specifically, it is composed of a linear Hall IC (Linear Hall IC) that can obtain an output voltage proportional to the magnetic field (magnetic flux density) of the magnet M.

When the interlocking member 2 rotates in the same direction as the throttle grip G is rotated, the magnet M attached to the interlocking member 2 also rotates in the same direction by the same angle. As a result, the magnetic field changes depending on the rotation angle, so a detection signal (output voltage) corresponding to the rotation angle can be generated and can be outputted to the outside via the output terminal 7. The output signal outputted through the output terminal 7 in this way is transmitted to the ECU (engine control unit) mounted on the motorcycle, and the engine (drive source) of the vehicle is controlled according to the transmitted output signal. It is now possible to do so.

The connector member B according to this embodiment is equipped with a plurality of rotation angle detection means 6 (two in this embodiment), and outputs a detection signal generated by each rotation angle detection means 6 with specific output characteristics to a terminal. As shown in FIGS. 12 to 14, in this embodiment, it is a cord type connector member B1.

As shown in FIGS. 12 to 14, the cord type connector member B1 has two rotation angle detection means 6 and an output terminal 7 connected to each other via an electric cord C, and the rotation angle detection means 6 are attached with the front and back reversed. and outputs respective detection signals. More specifically, the cord type connector member B1 consists of a piece-like component in which two rotation angle detection means 6 and an output terminal 7 are formed on a base material 9 made of a molded resin material, and one rotation angle detection means 6 is attached with its front surface facing the outside, and the other rotation angle detection means 6 is attached with its back surface facing the outside.

The output terminal 7 is made of a conductive metal such as a copper plate and extends from the base material 9, and is connected to each rotation angle detection means 6 via a flexible electric cord C. Then, as shown in FIG. 15, by inserting the board type connector member B2 into the accommodation recess 3b of the mounting portion 3a, the cord type connector member B1 is press-fitted and fixed, and the output terminal 7 is inserted into the accommodation recess 3b. It extends to the opening side and can be connected to a connector F on the vehicle side.

As a result, when the interlocking member 2 and the magnet M rotate in the same direction as the throttle grip G is rotated, the detection signal (output voltage) generated by the rotation angle detection means 6 on one side and the rotation angle on the other side are The detection signals (output voltages) generated by the angle detection means 6 have opposite trends (when one detection signal increases, the other detection signal decreases, and when one detection signal decreases, the other detection signal increases). trends).

Further, in the cord type connector member B1, a magnetic shielding member 8 is attached to the back side of the base material 9 (the surface opposite to the mounting surface of the rotation angle detection means 6). The magnetic shielding member 8 is composed of a plate-like member made of a material that shields magnetism, and as shown in FIGS. 4 and 5, a connector member B (cord type connector member B1) is attached to the case member 3. In this state, the rotation angle detection means 6 is covered and external magnetism is shielded.

On the other hand, the vehicle-side connection connector F connected to the output terminal 7 consists of a connector formed at the tip of a connection cord D extending from the vehicle side, and is sealed with a waterproof seal as shown in FIG. It is configured to include a member Fa and a female terminal Fb formed in a hole shape. As shown in FIG. The signal is transmitted to the vehicle via the connector F.

Furthermore, in this embodiment, when the connection connector F is connected to the output terminal 7, the sealing member Fa closes and seals the opening side of the accommodation recess 3b. That is, the accommodation recess 3b of the case member 3 is defined as an accommodation space S in which the interlocking member 2 and the magnet M in the case member 3 are accommodated, as shown in FIG. Since it is formed in the shape of a bag with an opening, when the connecting connector F is connected to the output terminal 7, the housing recess 3b is sealed with the sealing member Fa to be in an airtight state.

Another type of connector member B attached to the case member 3 may be a board type connector member B2, as shown in FIGS. 17 to 19. As shown in FIGS. 17 to 19, this board type connector member B2 has two rotation angle detection means 6 and an output terminal 7 connected to each other via a board K having a predetermined electric circuit, and the rotation angle detection means 6 detection signals are outputted via an electric circuit. More specifically, the board-type connector member B2 is composed of a piece-like component in which two rotation angle detection means 6 and an output terminal 7 are formed on a base material 10 made of a molded resin material, etc. 6 are mounted adjacently on the substrate K.

The output terminal 7 is made of a conductive metal such as a copper plate and extends from the base material 10, and is connected to each rotation angle detection means 6 via an electric circuit formed on the substrate K. Then, as shown in FIG. 20, by inserting the board type connector member B2 into the accommodation recess 3b of the mounting portion 3a, the board type connector member B2 is press-fitted and fixed, and the output terminal 7 is inserted into the accommodation recess 3b. It extends to the opening side and can be connected to a connector F on the vehicle side.

As a result, when the interlocking member 2 and the magnet M rotate in the same direction as the throttle grip G is rotated, the detection signal (output voltage) generated by the rotation angle detection means 6 on one side and the rotation angle on the other side are The detection signals (output voltages) generated by the angle detection means 6 have the same tendency (when one detection signal increases, the other detection signal also increases, and when one detection signal decreases, the other detection signal also decreases). trends).

According to the throttle grip device 1 according to the present embodiment, the case member 3 has the mounting portion 3a to which the connector member B to which the rotation angle detection means 6 and the output terminal 7 are attached can be attached. The rotation angle detection means 6 generates a detection signal with the connector member B attached, and since the vehicle-side connection connector F can be connected to the output terminal 7, the rotation angle detection means 6 can be connected to the case member 3. Workability during assembly can be improved.

Further, the mounting portion 3a is formed with an accommodation recess 3b capable of accommodating the connector member B, and the accommodation recess 3b is sealed in a state in which the connection connector F is connected to the output terminal 7, so that the accommodation recess 3b is in an airtight state. , the connector member B can be made waterproof by connecting the connector F. Furthermore, the connector member B according to the present embodiment is equipped with a plurality of rotation angle detection means 6 and is capable of outputting a detection signal generated by each rotation angle detection means 6 from an output terminal 7 with specific output characteristics. Therefore, failure diagnosis and monitoring can be carried out smoothly and accurately using specific output characteristics.

Furthermore, a cord-type connector member B1 can be used as the connector member B, and the cord-type connector member B1 is connected to the rotation angle detection means 6 and the output terminal 7 via the electric cord C, and the rotation angle detection means 6 and the output terminal 7 are connected to the cord type connector member B1. Since the means 6 are attached with the front and back reversed and respective detection signals are output, the plurality of rotation angle detecting means 6 can generate detection signals that change in opposite trends with respect to the rotation of the throttle grip G.

Further, a board type connector member B2 can be used as the connector member B, and the rotation angle detection means 6 and the output terminal 7 are connected to the board type connector member B2 via a board K having a predetermined electric circuit. Since the detection signal of the rotation angle detection means 6 is outputted via the electric circuit, an output signal corresponding to the electric circuit of the board K can be outputted.

In addition, since the connector member B (cord type connector member B1) can be attached with a magnetic shielding member 8 that covers the rotation angle detection means 6 while being attached to the case member 3 and shields external magnetism, By attaching the connector member B to the case member 3, the magnetic shielding member 8 can be assembled. Furthermore, in this embodiment, since the frictional resistance applying means 11 that generates frictional resistance when the interlocking member 2 rotates is provided, the operability of the throttle grip G can be improved by the frictional resistance generated when the throttle grip G is operated. can.

However, the case member 3 is capable of selectively attaching a connector member (B1, B2) having an arbitrary output characteristic among a plurality of connector members (B1, B2) having different output characteristics. Thereby, it is possible to easily produce an output that meets different requirements for each vehicle while suppressing increase in manufacturing costs. Further, the case member 3 according to this embodiment can optionally be attached with a cord type connector member B1 or a board type connector member B2. As a result, the type of rotation angle detection means 6 and the attachment form of the rotation angle detection means 6 to the connector member B can be appropriately selected, and output that meets the requirements of the vehicle can be easily performed. .

Although the present embodiment has been described above, the present invention is not limited thereto, and, for example, the connector member B that can be attached to the attachment portion 3a may have other output characteristics. Further, the throttle grip G may be adapted to be capable of forward and reverse rotation, and the return spring 4 may be replaced with other forms of biasing means. 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 case member has a mounting part to which the connector member to which the rotation angle detection means and the output terminal are attached can be attached, and the rotation angle detection means generates a detection signal with the connector member attached to the mounting part. As long as the throttle grip device has an output terminal that can be connected to a connector on the vehicle side, the present invention can be applied to a throttle grip device having a different external shape or having other functions added.
