Description

Stand position detection device

The present invention relates to an apparatus for detecting the position of a main stand or a side stand bar that is rotatably provided on a motorcycle.

The side stand attached to the two-wheeled vehicle is supported in a state where the side stand bar is lowered to the upright position when the two-wheeled vehicle is stopped to support the two-wheeled vehicle, and is stored in the storage position when the two-wheeled vehicle is running so that it does not interfere with traveling. In motorcycles, it is known to detect the position of the side stand bar so that the side stand bar does not travel in the upright position, and to control the engine so that it cannot travel in the upright position.

For example, Patent Document 1 includes a fixed member that is fixed to a vehicle body frame of a motorcycle and includes an upper case member and a lower case member, and a movable member that moves as the side stand bar rotates. A position detection device is disclosed in which either a magnet or a magnetic sensor is fixed to a member.

In the position detection device of Patent Document 1, a movable member is disposed between the upper case member and the lower case member, and when the side stand bar is in the standing position, the movable member is interposed between the magnet and the magnetic sensor to shield the magnetic field. However, the standing position and the storage position of the side stand are detected by preventing the magnetic field from being shielded at the storage position.

In the position detection device described in Patent Document 1, the magnetic sensor is disposed on a substantially rectangular printed board. In addition to the magnetic sensor, a determination circuit, an output circuit, an external output terminal, or the like is disposed on the printed board. In this apparatus, the position of the magnet is detected by a magnetic sensor, and the determination result is output from a terminal for external output via a determination circuit or an output circuit.

Moreover, as described in FIG. 1 of the publication, the position detection device described in Patent Document 1 is provided with a case member above the rotation shaft of the side stand, and a magnetic sensor or the like is disposed in the case member. Contains a printed circuit board.

In this apparatus, the case member protrudes greatly from the periphery of the rotation axis of the stand bar, and the case member may become an obstacle when a user of the motorcycle tries to operate the stand bar. In addition, when the magnetic sensor and other circuits are arranged on the printed circuit board as in the apparatus, the apparatus becomes large, and there is a disadvantage that the material cost of the electronic device and the substrate to be used increases. In addition, when manufacturing the apparatus, there is an inconvenience that the number of man-hours for assembling work such as mounting of an electronic device on the printed circuit board and incorporation of the printed circuit board after mounting into the case member are increased.

In order to solve the above-described problems, an object of the present invention is to provide a stand bar position detection device that has a small number of parts and can save space. Another object of the present invention is to provide a position detection device for a stand bar that can be easily assembled during manufacture.

In order to achieve the above object, a stand position detecting device according to the present invention includes a fixed portion attached to a vehicle frame, and a stand bar that can rotate around a rotation axis with respect to the fixed portion.

Disposed toward, and said input end of said external connecting terminals and the lead terminal is characterized by comprising directly bonded.

According to the stand position detecting device of the present invention, the magnetic sensor is arranged so as to face the magnetism generating member in the axial direction of the rotation shaft, so that it protrudes in the circumferential direction of the magnetism generating member as in the prior art. It is possible to reduce the part to be performed. Further, since the input terminal of the external connection terminal and the lead terminal of the magnetic sensor are directly joined, other members such as wiring and a substrate are not required. Therefore, according to the present invention, the number of parts can be reduced, and space can be saved.

It is preferable to project in the axial direction of the rotating shaft toward the terminal.

According to this configuration, since the output end is offset toward the magnetism generating member, the number of members arranged in the axial direction of the rotation shaft from the magnetism generating member can be reduced. This offset arrangement can be easily realized by projecting the input end toward the lead terminal.

Further, in the stand position detecting device of the present invention, it is preferable that the case member has a holding protrusion for holding the lead terminal between the sensor body and the input end. With this configuration, the magnetic sensor can be firmly fixed to the case member.

It is preferable to hold by the holding groove. According to this configuration, since the magnetic sensor is fixed by the holding groove at the input end, the magnetic sensor can be firmly fixed to the case member.
