Description

[Detailed explanation of the idea]

TECHNICAL FIELD The present invention relates to a device for preventing a motorcycle from forgetting to store its side stand while driving. Traditionally, when riding a motorcycle, it is often the case that the rider forgets to retract the side stand due to carelessness on the part of the rider.
Since the side stand comes into contact with a protruding object on the road surface or comes into direct contact with the road surface when turning, several devices have been proposed to prevent the vehicle from driving with the side stand up or to issue a warning. There is. Therefore, the present invention is designed to electrically connect a neutral switch, a clutch switch, and a side stand switch each having a driven relay, and to control an engine ignition system and a starter motor by the operation of the relays. The main purpose is to provide a prevention device. Hereinafter, the configuration of the present invention will be described with reference to embodiments. The drawing shows an electric circuit A of a device for preventing forgetting to store the side stand of a motorcycle. In the drawings, reference numeral 1 denotes a neutral switch, which is closed when a shift pedal (shift lever, not shown) is in a neutral position. Reference numeral 2 designates a clutch switch, which is opened when a clutch lever (not shown) is in an operating position (a state in which gears can be changed). 3 is a side stand switch, which is closed when the side stand (not shown) is in the upright position. Neutral switch 1, clutch switch 2
and side stand switch 3 are respectively driven by neutral switch relay 1a, clutch switch relay 2a and side stand switch relay 3.
It has a. The neutral switch relay 1a connects the movable contact 1b connected to the battery 5 via the main switch 4 to the first terminal 1d by exciting the excitation coil 1c when the neutral switch 1 is closed, while connecting it to the first terminal 1d when the neutral switch 1 is closed. Sometimes, it is configured to be connected to the second terminal 1e. This first terminal 1d is
Along with cell starter switch 6, diode 7
It is electrically connected to the igniter unit 8 via. Therefore, when the shift pedal is in the neutral position, if the starter switch 6 is closed, the excitation coil 6b of the starter relay 6a is energized and conductive at the movable contact 6c, so that the starter motor 9 is turned off from the battery. 5, thereby causing starting. On the other hand, the second terminal 1e is connected to the clutch switch relay 2.
It is connected to the movable contact 2b of a. The clutch switch relay 2a has a movable contact 2b
is connected to the first terminal 2d when the clutch switch 2 is open, and to the second terminal 2e when the clutch switch 2 is closed. The first terminal 2d is connected to the igniter unit 8 via the diode 7, and the second terminal 2e is connected directly to the first terminal 3 of the side stand switch relay 3a.
d, respectively. The side stand switch relay 3a connects the movable contact 3b connected to the igniter unit 8 to the first terminal 3 when the side stand switch 3 is opened.
d, and is configured to be connected to the second terminal 3e when closed. Reference numeral 11 denotes an ignition coil, which is connected in series to the main switch 4. This reduces the amount of current flowing through each of the driven relays 1a, 2a, 3a, and controls the amount of current flowing to the igniter unit 8. Reference numeral 12 denotes a neutral lamp, which is connected and wired in parallel with the excitation coil 1a of the neutral switch relay 1a, and is lit only when the shift pedal is in the neutral position. Note that 2c and 3c are excitation coils for the clutch switch relay 2a and the side stand switch relay 3a, respectively. The relationships between the switches 1, 2, and 3, the starter motor 9, and the engine ignition system are as follows.

[Table]
Next, the operation of the above device will be explained. (i) When the shift pedal is in the neutral position When the neutral switch 1 is closed (the main switch 4 is closed), the movable contact 1b of the neutral switch relay 1a is connected to the first terminal 1d. , a battery 5 is electrically connected to an igniter unit 8 via a cell starter switch 6 and a diode 7. As a result, the starter motor 9 and the engine ignition device become operable regardless of the state of the side stand. In this case, the shift pedal is in the neutral position, so the vehicle will not run. (ii) When the shift pedal is in the gear shifting position and the clutch lever is in the non-operating position When the neutral switch 1 is opened and the clutch switch 2 is closed, the movable contact 1b of the neutral switch relay 1a is connected to the second terminal 1e.
, the movable contact 2 of the clutch switch relay 2a
b are respectively connected to the second terminal 2e, so
Even if the starter switch 6 is closed, the starter relay 6a is not energized and the starter motor 9
becomes inoperable. On the other hand, when the engine ignition system is in the side stand storage position, the movable contact 3b of the side stand switch relay 3a is connected to the first terminal 3d.
The igniter unit 8 is connected to the battery 5 and ready for ignition. However, when in the upright position, the movable contact 3b is connected to the second terminal 3e, and the battery 5 and the igniter unit 8 are electrically connected. is shut off and ignition becomes impossible. In this way, when the side stand is upright, neither the starter motor 9 nor the engine ignition system operates, making it impossible to run the vehicle, thereby preventing the vehicle from erroneously running. (iii) When the shift pedal is in the gear shifting position and the clutch lever is in the operating position When the neutral switch 1 and clutch switch 2 are closed, the movable contact 1b of the neutral switch relay 1a is connected to the second terminal 1e, and the clutch lever is connected to the second terminal 1e. The movable contacts 2b of 2a are respectively connected to the first terminals 2d, thereby electrically connecting the battery 5 to the igniter unit 8 via the diode 7. As a result, the starter motor 9 and the engine ignition device become operable regardless of the state of the side stand. in this case,
Since the clutch lever is in the operating position, the vehicle will not be driven. Furthermore, while driving, there is no need to supply current to the excitation coil 2c of the clutch switch relay 2a, so as shown in FIG. A speedometer switch 21 (a relay may also be used) is provided, and when the speedometer operates, the speedometer switch 21
1 may be opened and the current supply to the excitation coil 2c may be cut off. As described above, the present invention electrically connects the neutral switch, clutch switch, and side stand switch each having a driven relay, and controls the engine ignition system and starter motor by the operation of the driven relay. It has the excellent effect of preventing
