Description

Description: TECHNICAL FIELD [0001] The present invention relates to a main switch structure used for a bar handle type vehicle, particularly for a motorcycle.

(Prior art)

Generally, the main switch of a motorcycle has a lock position and a parking position in addition to the on / off position of the electric system. In the latter position, the steering wheel is locked and the parking lock light is maintained by maintaining the steering lock. Can be turned on. Such a position is performed by rotating the rotor with a key.

Normally, the main switch is provided with an erroneous operation prevention function. When the key is rotated from the off position to the lock position, the key cannot be rotated to the lock position. That is, in order to switch from the off position to the lock position, the key must be pushed once and then turned, or the key cannot be turned to the lock position unless it is turned while pressed. However, since the vehicle can be rotated from the lock position to the parking position as it is, when the driver operates the key from off to lock, the driver sometimes passes the lock position and rotates to the parking position. Since the parking light is turned on at the parking position, the battery may rise if left unattended for a long time, making it difficult to start the next engine.

[Object of the invention]

An object of the present invention is to solve the conventional problems described above,
It is an object of the present invention to provide a main switch structure for preventing an erroneous operation such as switching from an off position to a parking position and directly to a parking position when performing a key operation.

[Configuration of the invention]

To achieve the above object, a main switch structure according to the present invention comprises a vertically extending cylindrical body, a rotor having a key hole at an upper end portion internally movably up and down, and the rotor being attached to the cylindrical body. In a main switch structure of a bar handle type vehicle, which is always positioned at an upper end side by a bias of a spring, and can be switched to each of ON, OFF, lock, and parking positions by rotating the rotor, In addition to a movable actuator, an engagement protrusion that engages with the upper end of the actuator and that prevents only rotation of the rotor from the off position to the lock position and from the lock position to the parking position is formed around the rotor upper end. A cam for operating the actuator coaxially and integrally rotatable with the rotor is provided below the actuator, and protrudes upward from the upper surface of the cam. The protrusions of the two positions formed along the circumferential direction that, one of the convex portion protrudes in a triangular shape and the two
One of the engaging projections is located substantially in the middle of the engaging projection, while the other is located in the trapezoidal shape and is located slightly on the side of the engaging projection engaged with the upper end of the actuator when in the off position. At the lock position, the rotor is pushed down and moved downward, and then returned to the original position, thereby releasing the engagement between the actuator and the rotor, and lowering the lower end of the actuator with the two convex portions. Position so as to abut the recess between the parts,
By rotating the rotor at the return position in contact with the recess, the lower end of the actuator rides on the protrusion, the upper end of the actuator is engaged with the engagement protrusion, and the lock position is shifted from the off position to the lock position. Alternatively, it is possible to switch from the lock position to the parking position.

 Hereinafter, the present invention will be described with reference to an embodiment shown in the drawings.

FIGS. 1 and 2 show a front part of a motorcycle provided with a main switch mechanism of the present invention. Reference numeral 20 denotes a head pipe at the front end of a vehicle body frame, and reference numeral 21 penetrates the head vip 20 so as to be rotatable left and right. The steering axis. An upper bracket 22 is fixed to the upper end of the steering shaft 21, and fitting holes 23, 2 at both left and right ends thereof are provided.
The front walk (not shown) is fixed to 3,
The main switch structure 1 of the present invention is fixed to the front end of the central portion.

The main switch structure 1 has a plan view as shown in FIG. 3, an internal structure as shown in FIG. 4, and an outline as shown in FIG. As shown in these drawings, the main switch structure 1 has a rotor 3 rotatably incorporated in a cylindrical body 2 of an outer shell, and the rotor 3 has a key hole 4 at an upper end portion into which a key K is inserted. . Then, by rotating the rotor 3 together with the key K, on (ON), off (OFF), lock (LOCK),
It can be switched to each position of the parking (P), and the ON / OFF operation of the main switch, the steering lock of the steering wheel, and the operation of turning on the parking light can be performed.

In the locked and parking positions, the upper bracket 22
The steering wheel (steering shaft 21) can be locked in a state where is turned to the left. At this time, the rotor 3 rotates the cam 6 in conjunction with it, and further rotates the eccentric cam 7 to push the slider 8 in a direction perpendicular to the rotor axis, thereby causing the lock bar 5 to protrude from the lower end of the cylindrical body 2, As shown in the figure, the head pipe 20 is locked by engaging with a stopper 24 fixed to the front surface thereof.

In the main switch structure 1, the rotor 3 rotatably provided in the cylindrical body 2 extending vertically includes:
Further, it is movable up and down in the direction of the rotor axis, and is always urged to the upper end side by a spring 9. An operator 10 movable around the rotor 3 in the axial direction of the rotor is provided around the rotor 3.
A cam 6 for operating is provided below. The cam 6 rotates integrally with the rotor 3 coaxially, but does not move in the axial direction but is relatively slidable. Further, the cam 6 and the eccentric cam 7 rotate integrally.

In addition, the rotor 3 has an engaging projection 3 that is freely engageable with and disengageable from the upper end 10a of the actuator 10 and that prevents the rotor 3 from rotating only from the off position to the lock position and from the lock position to the parking position.
a, 3b are provided at two locations along the circumferential direction. On the other hand, on the upper surface of the cam 6, convex portions 6a and 6b projecting upward and acting on the lower end portion 10b of the actuator 10 are formed at two places along the circumferential direction. One of the protrusions 6b is formed in a triangular shape and is located substantially in the middle between the two engagement protrusions 3a and 3b, and the other protrusion 6a is formed in a trapezoidal shape, and It is located on the front side in the circumferential direction from 3a, that is, on the slightly on position side.

Insert the key K into the rotor 3 of the main switch structure 1 having the above-described structure, and turn on (ON) → off (OFF) →
The operation for rotating the lock (LOCK) to the parking (P) position is as follows.

First, when the rotary operation is performed from the ON position to the OFF position, the engagement protrusion 3a of the rotor 3 is engaged with the upper end 10a of the actuator 10 at the OFF position as shown in FIG. . That is, in the process from ON to OFF, the lower end 10a of the actuator 10 is regulated upward by the projection 6a of the cam 6, so that the actuator 10 maintains the upper position and the rotor 3
5, the engaging projection 3a is caught on the upper end 10a as shown in FIG. 5, and cannot be further turned toward the lock position.

For this reason, in order to switch the rotor 3 from the off position to the lock position, it is necessary to perform operations as shown in FIGS. 6A to 6E.

First, as shown in FIG. 6A, the key K is pushed together with the rotor 3 in the direction of the arrow F, so that the lower end 10b of the actuator 10 has the projections 6a and 6b.
Press down until it touches the recess between. Thereby, the engagement between the engagement protrusion 3a of the rotor 3 and the upper end 10a of the actuator 10 is released. Next, when the pressing of the key K is released, only the rotor 3 urged by the spring 9 is pushed up as shown by the arrow G and returns to the original position as shown in FIG. The engagement protrusion 3a of the rotor 3 is pushed down and remains at a position where it is in contact with the concave portion.
Can pass through the upper end 10a. When the rotation is further continued in the direction of arrow I (lock position direction) as shown in FIG. 6D, the lower end of the operator 10 rides on the convex portion 6b of the cam 6 to push down the operator 10 and move it to the upper position. Therefore, in the locked position as shown in FIG. 6E, the upper end 10a of the actuator 10 engages with the engagement projection 3b of the rotor 3, and prevents further rotation to the parking position.

Therefore, in order to rotate the rotor 3 from the lock position to the parking position, the key K is depressed, the operator 10 is set to the lower position, and the rotation operation is performed in the same manner as when the rotor 3 is operated from the off position to the lock position. I have to.

Therefore, according to the main switch structure described above,
Erroneous operation of directly switching from the off position to the parking position through the lock position is eliminated.

Although the above-described embodiment is a case of a main switch of a motorcycle, the present invention can be similarly applied to a motorcycle or an automobile having a bar handle.

〔The invention's effect〕

The main switch structure according to the present invention includes an engagement protrusion that engages with an upper end of an actuator movable in an axial direction of the rotor and that prevents only rotation of the rotor from an off position to a lock position and from the lock position to a parking position. Two cams are provided on the upper end side along the circumferential direction, and a cam coaxially rotatable with the rotor is provided below the actuator, and two cams are formed on the cam along the circumferential direction. One of the portions protrudes in a triangular shape and is located substantially in the middle of the two engagement protrusions, while the other protrudes in a trapezoidal shape and is located slightly on the side of the engagement protrusion engaged with the upper end of the actuator when in the off position. Then, by pushing the rotor in the off position or the locked position of the rotor and returning it, the engagement between the operator and the rotor is released, and the rotor is rotated in this state, so that the lower end of the operator rides on the convex portion. Let it on The part is engaged with the engagement projection to enable switching from the off position to the lock position or from the lock position to the parking position, so that the key does not directly switch to the lock position past the off position, When switching from the off position to the lock position, it is possible to reliably prevent an erroneous operation such as switching directly to the parking position past the lock position,
Moreover, the structure for preventing both erroneous operations can be made compact.
