Description

  The present invention relates to a kickstand detection device, and more particularly, to a kickstand detection device having a function of suppressing a stand from standing when riding or a vehicle body from tilting when riding.

  Currently, there are a lateral stand 10 and a middle stand 20 in the stand of a motorcycle (bicycle, motorcycle, electric motorcycle, etc.) (the motorcycle is illustrated and described in the figure). Most stands are equipped with springs, support the vehicle body by standing upright, and are folded sideways while riding.

  However, in the conventional technology, when the two-wheeled vehicle is parked on the road, the front wheel 30 or the rear wheel 40 may be rotated by an inappropriate operation, and the motorcycle may fall. Also, if you forget to fold a stand (for example, the one-foot stand 10) when riding, the stand may come into contact with the ground when turning a curve, and the vehicle body may roll over.

  On the other hand, the manufacturer operates the wire rope indirectly by pressing a button to fold the side stand. Such a configuration allows the user to fold the horizontal stand without stopping while riding by folding the horizontal stand using a wire rope. However, since there is no prior notice, when the user accelerates and moves forward without the side stand being folded, the side stand may rub against the ground and the center of gravity may become unstable.

  This device prevents the side stand from being completely folded during riding. Conventional kickstand detection devices are classified into two types: contact type and non-contact type. A contact-type kickstand detection device (see, for example, Patent Document 1 and Patent Document 2) is characterized by the structure of a horizontal stand. When the side stand is at a specific position, the contact switch or the contact valve is operated by the contact method to start the engine of the vehicle body. However, this technical method requires the design of a lateral stand mechanism, and it is difficult to prevent foreign matter from entering between the mechanism and the switch, which may cause the switch to operate abnormally. Further, since the contact-type kickstand detection device is worn by contact, there is a problem that the service life is shortened, and wear due to long-term use leads to a failure of the lateral stand detection device.

  On the other hand, a non-contact type kickstand detection device (see, for example, Patent Document 3) employs a photoelectric detector and is configured such that a light shielding piece and a horizontal stand are interlocked. In this method, the problem of shortening the service life due to wear due to contact as described above can be avoided. However, there is a possibility that foreign matter may enter between the photoelectric detector exposed to the outside and the light-shielding piece, especially when the position of the horizontal stand is close to the chassis, dirt and dust are likely to enter, causing problems. there is a possibility. In addition, it is necessary to actively supply power to the photoelectric detector, and it is necessary to separately perform signal processing on the detection signal to suppress malfunction due to noise.

  Therefore, the present inventor considered that the above-mentioned drawbacks can be improved, and as a result of intensive studies, the present inventor has arrived at the proposal of the present invention for improving the problem reasonably and effectively.

  The present invention has been made in view of such conventional problems. In order to solve the above-mentioned problems, the present invention has as its main object to provide a kickstand detection device.

  Moreover, it is installed in the corresponding position, the relative position of each member can be adjusted, it can be adjusted according to the demand in use, it is not limited to the structure of the horizontal stand, and the current horizontal stand is controlled by the signal control unit. The main object of the present invention is to provide a kickstand detection device capable of accurately grasping the state of the vehicle and suppressing the tilting of the vehicle body.

  In order to solve the above-described problems and achieve the object, a kickstand detection device according to the present invention is a kickstand detection device applied to a motorcycle stand, and includes a magnetic detector and a magnetic element. The magnetic detector is installed on a fixed member below the vehicle body of the motorcycle, is located in the vicinity of the rotating shaft of the stand, and is electrically connected to the signal control unit by a signal transfer line. The magnetic element is installed on the stand and can rotate coaxially with the rotation axis of the stand. The signal control unit detects the relative position of the magnetic element and the magnetic detector.

Preferably, the stand is a middle stand located between a front wheel and a rear wheel of the two-wheeled vehicle or a side stand provided on a side of the two-wheeled vehicle.
Preferably, when the stand is folded, the magnetic detector and the magnetic element are superposed, and the impedance of the magnetic detector detected by the signal control unit is zero according to the magnetic force detected by the magnetic detector. When the stand is standing, the impedance of the magnetic detector detected by the signal control unit is infinite according to the magnetic force detected by the magnetic detector.

  According to the present invention, the detection device including the magnetic detector and the magnetic element detects the state of the stand by the signal control unit, and suppresses that the stand is not folded when getting on. The detection system according to the present invention is a non-contact detection system and is different from the contact detection system. Adopting a magnetic detection method, unlike the photoelectric detection method, it can suppress the occurrence of problems due to dirt and dust, it is not necessary to add a separate power source to the detector, and interference due to noise can be suppressed , Can increase the reliability.
