A lock mechanism is formed by the lock pin and the lock hole so that the lock pin can be pulled in against the biasing force to release the engagement between the lock pin and the lock hole, and the rotating part can be rotated, thereby improving shift operability. It is an object of the present invention to provide a transmission device for an electric transmission that can improve the speed change, prevent malfunctions of the transmission, and reliably perform a speed change operation.

[Means for solving the problem] In order to achieve this purpose, this invention provides a light emitting element on the side of the handle grip attached to one end of the handlebar, and a light receiving element on the side of the handle switch box to issue a gear change command. A transmission device for an electric transmission having a shift command switch section, which has a lock hole near the outer periphery between the handle grip and the handle switch box, and has a light guide path inside that connects the light emitting element and the light receiving element. A lock pin is provided in the handle switch box and is biased toward the rotating portion and engages with the lock hole, and the lock pin and the foot operation lever are connected by a wire cable. are connected to each other, and only when the foot operating lever is depressed, the locking pin is pulled in against the biasing force through the wire cable, and the engagement between the locking pin and the locking hole is released, and the rotating portion can be rotated. In order to achieve this, the locking pin and the locking hole constitute a locking mechanism.

[Function] With the above-described structure, the locking mechanism locks the rotating side for gear shifting operation during non-shift operation to prevent malfunction, and the locking mechanism is locked by the foot operation lever during gear shifting operation. The gear is released, and then the rotating side is rotated to perform a gear change operation.

A light emitting element 14 and a light emitting element driving circuit 16 are provided on the side of the handle grip 6 attached to one end, that is, the left end of the handlebar 4.
Further, a light receiving element 18 is provided on the handle switch box 8, and a light receiving signal processing circuit 20 is provided.
will be established. The light emitting element 14 and the light receiving element 18 constitute a shift command switch section 22.

A rotating part 24 is rotatably provided between the handle grip 6 and the handle switch box 8, and is attached to the left end of the handlebar 4. As shown in FIGS. 7 and 8, this rotating part 24 is comprised of a disc-shaped member 26, a small-diameter cylindrical sliding part 28 fixed concentrically to both planes of this disc-shaped member 26, It is constituted by a speed change lever 30 fixed to the outer periphery of the disc-shaped member 26. At this time, a plurality of half-lock lock balls 32 and lock holes 36 of the lock mechanism 34, which will be described later, are bored in the vicinity of the outer peripheral edge of the disc-shaped member 26 at predetermined locations, and a disc-shaped member inside the sliding portion 28 is provided with a plurality of holes. 26 is provided with a light guide path 38 that connects the light emitting element 14 and the light receiving element 18.

Further, a plurality of holes 40 are formed on the rotating portion 24 side of the handle switch box 8, and the lock ball 32 and the lock pin 44 of the lock mechanism 34 are arranged in the holes 40 via a spring 42. This lock pin 44 is connected to a wire cable 48, which will be described later, and is urged toward the rotating portion 24. Furthermore, a contact switch 46 is provided at the rear of the lock mechanism 34.
The contact switch 46 is connected to a foot, for example, a left foot operation lever 50 via a wire cable 48. At this time, the locking mechanism 34 is locked by turning on the contact switch 46.

The light emitting element drive circuit 16, the light reception signal processing circuit 20, the control section 10, and the actuator 12 are connected by signal lines 52, respectively. Note that reference numeral 54 indicates a rotating portion 24 provided on the handle switch box 8.

Further, when the rotating portion 24 is rotated, a half-lock is achieved by the engagement between the lock hole 36 and the lock ball 32 when the rotating portion 24 is located at a predetermined position.
The stop position of the rotating portion 24 can be easily determined. Thereafter, by stopping the operation lever 50 and returning it to its original position, the wire cable 4
8, the contact switch 46 is turned on, and the lock pin 44 is advanced by the biasing force of the spring 42 and inserted into the lock hole 36, thereby locking.

Further, after the speed change operation, the light receiving signal processing circuit 20
detects the shift position, displays the shift position with a lamp on the display section 58, and inputs a detection signal to the control section 10 to perform the shift operation.

Further, the contact switch 46 notifies the control section 10 whether or not a speed change operation is being performed in the rotating section 24 by means of ON/OFF signals, thereby contributing to smooth speed change control by the control section.

This makes the speed change operation extremely easy, and by reducing the number of contact points, the speed change operation can be performed quickly and reliably.

Furthermore, by unlocking the rotating portion using the foot operation lever, malfunction of the rotating portion can be reliably prevented, contributing to safe vehicle running.

[Effects of the invention] As explained in detail above, according to this invention, the circuit has a lock hole near the outer periphery between the handle grip and the handle switch box, and has a light guide path inside that connects the light emitting element and the light receiving element. The moving part is formed of a disc-shaped member, a lock pin which is biased toward the rotating part and engages with the lock hole is arranged in the handle switch box, and the lock pin and the foot operation lever are connected by a wire cable. The lock pin and the lock hole are provided so that only when the operation lever is depressed, the lock pin is pulled in against the biasing force through the wire cable, and the engagement between the lock pin and the lock hole is released, and the rotating part can be rotated. Since the mechanism is configured, the gear shifting operation becomes extremely easy, and together with the reduction in the number of contact points, the gear shifting operation can be carried out quickly and reliably. Moreover, by releasing the lock of the rotating part using the foot operating lever, it is possible to reliably prevent the rotating part from malfunctioning, thereby ensuring safety when the vehicle is running.
