Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a side stand detection device for detecting storage and protrusion of a side stand in a motorcycle or the like.

[Conventional technology]

Motorcycles are equipped with a side stand that protrudes diagonally from either side of the lower center of the vehicle body, but when this side stand is not retracted (protruded) or is deaf, the engine ignition is disabled and the engine is stopped. For example, this type of device is disclosed in Japanese Utility Model Application Publication No. 58-178023.

[Problems to be Solved by the Invention C] However, in conventional side stand detection devices of this type, a side stand switch that is operated directly by the movement of the side stand's retraction protrusion is used. It had to be installed at the bottom of the vehicle body.

For this reason, the side stand switch is likely to be covered with muddy water, and vibrations acting on the side stand switch are large, so consideration must be given to maintain accurate switch operation.

[Purpose of the invention]

The present invention has been completed in view of the above-mentioned problems in the prior art, and provides a side stand detection device for a motorcycle that can protect the side stand switch from muddy water and vibrations and further improves reliability. be.

[Means to achieve the purpose]

The present invention achieves the above object by installing a side stand switch at a position distant from the side stand and connecting the side stand and the side stand switch via a remote control member.

〔Example〕

The present invention will be specifically described below with reference to the drawings.

FIG. 2 shows an electric circuit of a side stand storage prevention device suitable for using the side stand detection device according to the present invention.

In FIG. 2, the ignition circuit 10 is configured to generate a high voltage at a predetermined timing as the engine rotates, and to cause a spark discharge from a spark plug (not shown) in the fuel chamber to operate the engine.

This ignition circuit 10 is configured so that when its terminal 11 is connected to ground, it is turned on to ignite the engine, and when the terminal 11 is disconnected from ground, it is turned off and stops ignition.

By the way, the terminal 11 is connected to the ground through three contacts connected in parallel: a clutch switch 12, a neutral switch 13, and a side stand switch 14. The engine is configured to ignite if it is in a conductive (on) state.

The clutch switch 12 detects the connection of the clutch, and is normally mounted so as to be operated using the movable part of the clutch operating lever.

The neutral switch 13 is a switch that detects the neutral state of the transmission, and is turned off in a non-neutral state and turned on only in a neutral state.

The side stand switch 14 is a switch that detects whether the side stand is retracted. 3 (projected! 3) turns it off, and turns it on in the retracted state.

The clutch switch 12 is composed of a changeover switch ν, and when the clutch is connected (the clutch lever is not gripped and the clutch is not operated), the terminal 11 of the ignition circuit 10 is connected from the ground as shown in the figure. When the clutch is disconnected (the clutch lever is operated and the clutch is disengaged), the terminal 11 is connected directly to the ground via the diode DI.

The neutral switch 13 is turned off as shown in the figure in a non-neutral state, and turned on in a neutral state, grounding the terminal 11 of the ignition circuit 10 via the diode D2 and making it possible to ignite.

The side stand switch 14 is turned off as shown in the figure when the side stand is out and in the non-retracted state, and is turned on when the side stand is retracted and the terminal 11 is turned off.
is grounded through diode D3 to enable ignition.

The present invention relates to an improvement of a side stand detection device that includes the side stand switch 14 and electrically detects whether the side stand is retracted or protruded. Indicate the case.

In FIG. 1, a body frame 20 of a motorcycle or the like connects a steering wheel pad 21 with left and right upper main members 22 and a lower main member 2a, and a seat rail 24 and a seat rail 24 on the rear side of these left and right main members 22 and 23. It has a schematic configuration in which angle members 25 are connected and the left and right sides are connected by appropriate cross members (not shown).

An engine 26 and various accessories are installed between the upper main member 22 and the lower main member 23.

A front fork 27 that supports the front wheels is attached to the front part of the body frame 20 via a steering head 21, and a rear fork 28 that supports the rear wheels is attached to the body frame 20f&.

A side stand 30 is pivotally supported on a support shaft 29 provided at the lower part of the vehicle body frame 20.

This side stand 30 rotates between a storage position (during driving, etc.) shown by a solid line and a protruding position (upright position! 3) shown by a two-dot chain line.

A tension spring 31 is connected between the side stand 30 and the vehicle body frame 20, and the side stand is held in the extended or retracted position by its spring force and stopper means.

A side stand switch 14 that detects whether the side stand 30 is extended or retracted is mounted inside the vehicle body away from the operating range of the side stand.

In the illustrated example, it is attached to the upper center of the vehicle body frame 20.

The side stand 30 and the side stand switch 14 are connected by a remote control member 33.

In the illustrated example, a rotary switch is used as the side stand switch 14, and a control cable is used as the remote control member 33.

Thus, when the side stand 30 is in the retracted position shown by the solid line, the control cable 33 is in the inactive return state, and the side stand switch 14 connected thereto
The lever 32 is in the normal position shown by the solid line, and the switch is in the on (closed) state, so that the ignition circuit 10 in FIG. 2 is in a state where the engine can be operated.

On the other hand, when the side stand 30 is in the protruding position (upright position) shown by the two-dot chain line in FIG. The lever 32 of 14 is biased to the position shown by the two-dot chain line, and the side stand switch 14 is turned off (opened).

Therefore, when used in a device for preventing forgetting to store the side stand as shown in FIG. 2, the ignition circuit 10 becomes unable to ignite unless either the tarlatch switch 12 or the neutral switch 13 is turned on (conducting). That is, when the clutch is connected and the transmission is in a power transmission disabled state, if the side stand 30 is in the non-retracted state, the engine will be stopped, and the engine will stop when the side stand is not retracted.

is now unable to start.
According to the side stand detection device described above with reference to FIG. Ta.

Furthermore, since the mounting position of the side stand switch 14 can be freely selected, the degree of freedom in design can be improved.Moreover, the mounting position, which was conventionally located near the footrest, can be moved to another location so that it is closer to the driver's feet. It is no longer necessary to pay attention to interference.

Furthermore, the side stand switch 14 can be mounted with anti-vibration support such as a rubber mount if necessary, and its durability can be further improved.

Furthermore, since the side stand switch 14 is installed inside the vehicle body covered with a cover such as a side cover,
The side stand, the lead wire (harness), etc. can be stored inside, and the appearance can be improved and the harness can be easily handled.

In the illustrated embodiment, the present invention is applied to a device for preventing forgetting to store the side stand, which disables the engine ignition circuit 10. However, the present invention is applicable to a device that detects whether the side stand 30 is stored or not, by using a buzzer or flashing lamp to prevent the side stand from being forgotten. It can be used in various devices such as a device that warns of non-retraction.

In addition, the switch is not limited to the rotary type, but the PUSH-PU
LL etc. can also be used.

Further, as the remote control member 33, in addition to a control cable, a transmission structure consisting of a rod, a link, etc. can be adopted.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, there is provided a side stand detection device that is excellent in waterproofness and anti-vibration properties, and can also achieve increased freedom in design and improved appearance.
