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.

The large protrusion 59d is formed at a position and shape that can just pass through the large cutout 57f of the connecting member 57, and the small protrusion 59e is formed at a position and shape that can just pass through the small cutout 57g of the connecting member 57. ing. The large protrusion 59d cannot pass through the small cutout 57g. An engagement groove 59f with which the engagement protrusion 57h of the connection member 57 can be engaged is formed on the surface of the large protrusion 59d on the flange 59b side.

  Further, as shown in FIG. 11B, the dimension from the surface on the headlight housing 35 side of the flange portion 57e of the connection member 57 to the end surface on the side opposite to the headlight housing 35 of the main body 57a (H in FIG. 11B). Is the same as the dimension from the surface of the large protrusion 59d and the small protrusion 59e of the retaining member 59 on the flange 59b side to the surface of the flange 59b on the headlight housing 35 side. The flexible shaft 58 has a thickness that can be inserted into the opening 57 d of the connection member 57 and the inner diameter side of the retaining member 59. However, the engaging member 60 at the tip of the flexible shaft 58 is sized such that it can pass through the opening 57d of the connecting member 57 but cannot pass through the inner diameter side of the retaining member 59. As shown in FIG. 10, the flexible shaft 58 is inserted through a retaining member 59 in advance, and an engagement member 60 is fixed to the tip thereof.

  The main body 59a of the retaining member 59 is inserted into the opening 57d of the connecting member 57 so that the large protrusion 59d passes through the large cutout 57f and the small protrusion 59e passes through the small cutout 57g. At this time, the engaging member 60 is engaged with the operation end 39 of the optical axis adjusting device 38 at the same time. Next, when the handle 59c of the retaining member 59 is held and rotated, as shown in FIGS. 11B and 11C, the engagement protrusion 57h of the connection member 57 is inserted into the engagement groove 59f of the large protrusion 59d. Engages with snapping. In this way, the large protrusion 59d and the small protrusion 59e engage with the flange portion 57e of the connection member 57, so that the retaining member 59 does not fall off the connection member 57.

  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 connecting member 57, the engaging member 60 is restricted by the tip of the retaining member 59 and does not come off from the operation end portion 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.
