Description

  The present invention relates to a headlight mounting device and a motorcycle. More particularly, the present invention relates to a headlight mounting device for mounting a headlight assembly on the front portion of a vehicle body, and a motorcycle including the headlight mounting device.

  Conventionally, a headlight is attached to the front of a motorcycle. The headlight has a bulb (bulb) covered by a cover having a front transparent lens surface and a rear reflector (reflector), and the periphery thereof is surrounded by a housing and a cowling. There is one in which this headlight is combined with an instrument panel, a horn assembly, and an optical axis adjusting (aiming) tool (see, for example, Patent Document 1). This is called a headlight assembly and has a considerable weight. This headlight assembly is connected to the head pipe of a motorcycle by a headlight housing brace comprising a pipe frame. Specifically, almost four corners of the headlight are fixed to the housing by fastening members such as bolts, and the left and right ends of the housing and the central lower end of the headlight are fixed to the headlight housing brace by bolts or the like. . The instrument panel is attached to the rear portion of the headlight assembly at a plurality of locations by bolts or the like.

  Patent Document 2 also discloses an attachment mechanism for attaching the headlight assembly to the head pipe of a motorcycle. As shown in FIG. 12, the attachment mechanism includes a cowling brace 101 and a plate-like headlight stay 102. The headlight assembly 103 is fixed to the cowling brace 101 via the headlight stay 102 by bolts 104 at almost four corners thereof, and the cowling 105 is also fixed to the cowling brace 101 by bolts at both right and left ends. Further, a meter 106 is attached to the upper part of the cowling brace 101 with a bolt 107. The base end portion of the cowling brace 101 is fixed to the head pipe 108.

  As described above, in both Patent Documents 1 and 2, the headlight assembly and meters are attached to the headlight housing brace (cowing brace) by bolts around the headlight assembly and the meters, and the cowling and the head at the bolt part. The weight of lamps, meters, etc. is supported.

However, since a headlight assembly having a considerable weight or the like and a mounting device such as a brace for supporting the weight are bolted in many parts, it takes much time to assemble. Further, since the weight of the headlight assembly or the like is supported by these bolt connecting portions, it is necessary to form the portion firmly. This point also makes manufacturing difficult.

  At the same time, the small protrusion 59e comes into contact with the stopper 57j of the connection member 57, and further rotation of the retaining member 59 is prevented. The large protrusion 59d, the small protrusion 59e, the engagement protrusion 57h, and the stopper 57j are formed to have such a positional relationship. Further, since the retaining member 59 is fixed to the connection member 57, the engaging member 60 is restricted by the tip of the retaining member 59 and does not come off the operation end 39. By rotating the knob member 61 of the remote operation tool 56 connected in this way, the optical axis adjusting device 38 meshed with the engaging member 60 can be rotated around the axis via the flexible shaft 58. The optical axis of the headlight 20 can be adjusted.

  The optical axis adjusting device 38 is configured to engage the engaging member 60 of the remote operation tool 56 with the operation end 39 and directly rotate the engaging end 60, but is not limited to this configuration. For example, the operation end portion can be formed after interposing a reduction gear. By carrying out like this, the required rotational operation force added to the remote control tool 56 can also be made small.

  According to the remote control tool 56 having the configuration described above, in the assembling process of the motorcycle 1, the retaining member 59 is inserted into the opening 57d of the connecting member 57 and is rotated only slightly. It can be connected firmly. Therefore, it contributes to man-hour reduction compared with the prior art which needs to screw several places.

  The headlight mounting device according to the present invention is not limited to the above-described embodiments, and the configuration can be changed, added, or deleted without departing from the spirit of the present invention.

  According to the present invention, it is easy to incorporate a headlight into a vehicle, and the assembly time is reduced. In addition, the headlight assembly can be prevented from vibrating and rotating, and a stable mounting state can be realized. Therefore, the present invention is particularly useful for a motorcycle in which a headlight is attached to the front portion of the vehicle body.
