  As described above, the wind screen 113 is disposed above the front cowling 112. Here, the support structure of the wind screen 113 will be briefly described. In the present embodiment, the wind screen 113 has a variable mechanism that supports the wind screen 113 so as to be movable up and down. As shown in FIG. 4, the variable mechanism 128 is disposed on the rear side of the wind screen 113 (the back side, that is, the occupant M side). In this example, it is arranged using the space inside the front meter panel 116 of the meter 114, and detailed illustration is omitted, but a base plate 129 fixed to the vehicle body frame side via a bracket or the like and fixed on the base plate 129. A pair of left and right guide rails 130 are provided. The guide rail 130 is inclined and arranged at a predetermined angle so as to rise rearward along the front-rear direction. As a specific configuration of the guide rail 130, for example, it may have a concave guide groove.

  On the other hand, a slider 131 that is supported so as to be disposed corresponding to the guide rail 130 is attached via a bracket 132 that is fixed near the lower portion of the back surface of the wind screen 113. The slider 131 is slidably engaged with the guide groove of the guide rail 130, whereby the wind screen 113 can reciprocate a predetermined stroke up and down at a predetermined inclination angle along the guide rail 130 (FIG. 4, arrow X). ) Note that an actuator including a drive motor or the like is used as a drive source for moving the wind screen 113 up and down, and the actuator can be operated by a manual switch, or the actuator can be automatically controlled according to the vehicle speed or the like. In such cases, the positioning is fixed at least at the upper and lower stroke ends of the reciprocating movement of the wind screen 113, that is, in two stages, or arbitrarily positioned and fixed in several places including the middle of the reciprocating stroke, that is, in three stages or more. Can be.

  Further, as shown in FIG. 3 or the like, the wind screen 113 further includes a substantially transparent screen main body 113A formed in a substantially trapezoidal shape or the like that is moderately narrow from the wide lower end side toward the upper end side, and its It has a non-transparent cover 113B attached along the lower edge. The cover 113B can also be attached and fixed via the bracket 132. As shown in FIG. 3 and the like, the cover 113B has a belt-like shape having a constant width in the vertical direction and extends to the entire width of the screen body 113A. Since the cover 113B is non-transparent, it is possible to hide a member or a component behind the cover 113B when viewed from the front.

  In the above case, in this example, a vertical function of the wind screen 113 is provided as a typical function of the variable mechanism 128. In addition to the vertical position variable function, for example, a function such as changing an inclination angle or changing a shape. Is provided. Thus, the variable mechanism 128 has a variable function that can arbitrarily change its shape and shape including the position of the wind screen 113 (these are collectively referred to as “modes”).

  As described above, the wind screen 113 is configured to be movable up and down, and is positioned at the rising end of the vertical movement as shown in FIG. 5, and is positioned at the falling end of the vertical movement as shown in FIG. 5A is a front view around the wind screen 113 at the rising end, and FIG. 5B is a side view thereof. 6A is a front view around the wind screen 113 at the descending end, and FIG. 6B is a side view thereof.

  Next, FIGS. 7 and 8 show the internal structure of the vehicle body cover at the front of the vehicle. FIG. 7 shows a state when the wind screen 113 is raised, and FIG. 8 shows a state when the wind screen 113 is lowered. First, in these drawings, a steering head pipe 134 is coupled to a front top portion of a vehicle body frame 133, a part of which is shown, and the front fork 101 is supported via the steering head pipe 134 as described above. The meter 114, the headlamp 126, and the like are mounted and fixed directly or indirectly through a support structure or a support member 135 made of appropriate brackets and stays using the vehicle body frame 133 and the steering head pipe 134.

  Now, in the embodiment of the present invention, first, there is a gap between the wind screen 113 and the front meter panel 116 as shown in FIG. 7 and the like. A ventilation path 11 (screen back side ventilation path) is formed along the back side (rear side). Further, in this example of the front meter panel 116, as shown by the oblique lines in FIG. 5 (A) and the like, a wind guide portion 1 is provided at the central portion in the left-right direction so that the front meter panel 116 is recessed rearward. The traveling wind 10 is taken into the vehicle body cover from the portion 1. As shown in FIG. 7 or FIG. 8, the air guide portion 1 has an air guide port 2 at the back of the recessed air guide portion 1. The air guide port 2 is located at the front portion of the vehicle body cover and is substantially opened forward, and communicates the inside and outside of the vehicle body cover.

  The wind screen 113 moves up and down on the front side of the front meter panel 116, but the periphery of the lower end thereof, that is, the cover 113 </ b> B is arranged so as to hang down and cover the air guide portion 1 from above. As shown in FIG. 7, when the wind screen 113 is raised, the cover 113B is positioned immediately before the wind guide portion 1, and as shown in FIG. 5A, a part (lower part) of the wind guide portion 1 is the cover 113B as viewed from the front of the vehicle. Approach to the extent that it is exposed from below. At this time, the overlap (overlap) area between the wind screen 113 and the wind guide portion 1 is relatively small, and the wind guide portion 1 is substantially open. In this case, the air duct 2 itself is not substantially exposed in appearance when viewed from the front of the vehicle.

  On the other hand, as shown in FIG. 8, when the wind screen 113 is lowered, the cover 113B is positioned below the air guide portion 1, and as shown in FIG. 6A, the air guide portion 1 is viewed from the lower side of the cover 113B as viewed from the front of the vehicle. There is no exposure. At this time, the overlapping area of the wind screen 113 and the wind guide portion 1 is relatively large, and the wind guide portion 1 is substantially closed in a front view. Thus, according to the vertical movement of the wind screen 113, the overlapping area of the wind screen 113 and the air guide portion 1 in the vehicle front view changes in size.

  Further, in the vicinity of the upper end portion of the front meter panel 116, an air exhaust portion 3 is provided on the rear side of the wind screen 13 as shown in FIG. 7 or FIG. An exhaust port 4 that opens upward is formed in the exhaust unit 3. As shown in FIG. 5A, this example has a pair of left and right exhaust ports 4 in the center distribution. A part of the traveling wind 10 taken from the wind guide portion 1 to the inside of the vehicle body cover flows toward the exhaust port 4 along the substantially back side (rear side) of the front meter panel 116 as indicated by an arrow. Form.

  Further, an air exhaust section 5 is provided near the rear portion of the front panel 118 as shown in FIG. 7 or FIG. The wind exhaust portion 5 is formed with a wind exhaust port 6 that opens to the occupant M (see FIG. 1) side. As shown in FIG. 2, in this example, a single air exhaust port 6 is provided at the center in the left-right direction of the vehicle. A part of the traveling wind 10 taken from the wind guide portion 1 to the inside of the vehicle body cover forms an internal ventilation path 13 that flows through the vehicle body cover and flows toward the exhaust port 6 as indicated by an arrow.

  Here, with respect to the shape of the cover 113B, referring to FIG. 9 (when the wind screen 113 is raised), the cover 113B has a throttle portion 7 in which a part of the cover 113B protrudes toward the front meter panel 116 side. In this example, a pair of throttle portions 7 spaced apart from each other in the left-right direction so as to sandwich the air guide portion 1 are formed, and by providing these throttle portions 7, particularly when the wind screen 113 is raised (FIG. 10). 9), the cross-sectional area of the screen back side ventilation path 11 shown by the alternate long and short dash line in FIG. 9 is reduced. When the wind screen 113 is raised, the aperture portion 7 is formed such that the cross-sectional area protruding toward the front meter panel 116 gradually increases, and is maximized at the rising end position.

The vehicle windshield device of the present invention is configured as described above. Next, the main effects and the like will be described.
As shown in FIG. 5B or FIG. 6B, when the vehicle travels, the traveling wind 10 is received from the front. Can be prevented. In this case, since the wind screen 113 is movable, an appropriate windproof effect can be obtained by raising and lowering the wind screen 113 according to the traveling speed of the motorcycle 100. On the other hand, since the wind screen 113 is raised particularly during high-speed traveling, a negative pressure region S is generated behind the wind screen 113 and the front panel 118 as shown in FIG. It becomes a factor.

  In the present invention, the aspect of the wind screen 113 is changed by the variable mechanism 128 in accordance with the situation of the vehicle. Specifically, according to the vertical movement of the wind screen 113, the overlapping area of the wind screen 113 and the air guide portion 1 in the front view of the vehicle changes in size, that is, it has a function of opening and closing the air guide port 2 with respect to the wind screen 113. Make it. For example, when the wind screen 113 rises during high-speed traveling, the wind guide portion 1 is opened as shown in FIG. 5A, and a part of the running wind 10 taken from the wind guide portion 1 is part of the internal ventilation path 12 and The air is exhausted from the exhaust port 4 of the exhaust unit 3 or the exhaust port 6 of the exhaust unit 5 through the internal ventilation path 13.

  In this way, by taking the traveling wind 10 from the wind guide portion 1 and discharging it from the exhaust ports 4 and 6, the generation of the negative pressure region S at the front of the occupant M is alleviated, or the meters of the meter main body portion 115 are reduced. Can be cooled. As described above, when it is necessary to take in the traveling wind 10 for relaxation of the negative pressure, cooling of the equipment, or the like, the air guide port 2 is opened to make it easy to actively take in air from the front of the vehicle. On the other hand, when it is not necessary to take in the traveling wind 10 such as during low speed traveling, the wind screen 113 is lowered to substantially close the air guide section 1 and at the same time, the effect of reducing the air resistance is exhibited. To do.

Further, the wind screen 113 that moves up and down by the variable mechanism 128 covers the air guide portion 1 more widely at the lower end position than at the upper end position.
That is, when the wind screen 113 is raised, the overlap area between the wind guide portion 1 and the wind screen 113 is small as viewed from the front of the vehicle as shown in FIG. Thus, the overlap area between the two becomes large.

  In general, during high speed traveling, where the wind screen 113 is often raised, a strong negative pressure is generated behind the front panel 118 and the wind screen 113, so that the negative pressure mitigating effect by guiding the traveling wind is large. Under this situation, the air guide portion 1 is arranged so as to be exposed from the lower edge of the wind screen 113 when viewed from the front of the vehicle, thereby making it easy to take in air from the front of the vehicle. And since more air can be sent behind the front panel 118 and the wind screen 113, a negative pressure state can be relieve | moderated effectively and comfort improves. On the contrary, when the vehicle is traveling at a low speed where the wind screen 113 is often lowered, the generated negative pressure itself is weak and it is not necessary to take in the traveling wind. At this time, the wind screen 113 covers the wind guide portion 1. By doing so, the wind guidance more than necessary for the occupant M is suppressed, and the comfort is improved.

  Further, the wind screen 113 covers the entire area of the air guide portion 1 at the lowered end position when the vehicle is viewed from the front. That is, as shown in FIG. 6A, when the wind screen 113 is lowered, the wind guide portion 1 is completely covered as viewed from the front of the vehicle.

  Under the situation where the wind guide is not required, unnecessary air flow is stopped for the occupant M, thereby improving the comfort of the occupant M. In this case, the wind guide unit 1 is arranged immediately after the wind screen 113 so as to be within the movable range (this range is an area where other parts such as the headlamp 126 cannot be arranged). As shown in FIG. 6 (A), the air guide portion 1 is completely hidden and an excellent appearance can be obtained. In addition, the arrangement of other components located on the front surface of the front cowling 112, such as the headlamp 126, and the degree of freedom in design are improved.

  Further, the wind screen 113 includes a substantially transparent screen body 113A and a non-transparent cover 113B that covers a lower portion of the screen body 113A. In this case, the cover 113B covers substantially the entire area of the wind guide portion 1 at the descending end position of the wind screen 113 when the vehicle is viewed from the front.

  As shown in FIG. 6A, by providing the wind guide portion 1 at a position hidden by the non-transparent cover 113B, the wind guide portion 1 positioned in front of the vehicle body can be hidden when the wind screen 113 is lowered when the vehicle is stopped. it can. By making the surroundings of the air guide portion 1 invisible in this way, the appearance can be improved and the appearance can be improved.

  Further, the screen back side ventilation path 11 is provided on the back side of the wind screen 113. The air guide section 1 is located on the front surface of the front meter panel 116 and communicates with an intermediate portion of the screen back side ventilation path 11, and the cross sectional area of the screen back side ventilation path 11 decreases as the wind screen 113 moves upward.

  In other words, the movable wind screen 113 whose mode can be changed according to the situation of the vehicle or the like has a function of restricting the screen rear side air passage 11. When traveling wind needs to be taken in to reduce negative pressure, particularly when the wind screen 113 is raised, negative pressure is generated extensively. At this time, by narrowing the cross-sectional area of the screen back side ventilation path 11, A larger amount of air taken from the front of the front cowling 112 can be guided to the air guide section 1, and not only the rear of the wind screen 113 but also the rear of the front meter panel 116 or the front panel 118, that is, the front of the passenger M. Since induction is possible, even with a small number of air inlets 2, the negative pressure can be relaxed in a wider range, and comfort is improved.

  As described above, in the windshield device of the present invention, the traveling wind 10 is basically not taken in from the wind guide portion 1 at the normal speed including a relatively low speed, thereby suppressing unnecessary wind entrainment and the like. On the other hand, particularly when traveling at high speed or when it is necessary to capture the traveling wind 10 for equipment cooling, the air guide 2 is opened to facilitate capturing the traveling wind 10 actively. As described above, the traveling wind 10 can be effectively captured according to the state of the vehicle and the like, instead of simply capturing the traveling wind 10 from the wind guide portion 1. At that time, the degree of freedom in designing other parts around the apparatus can be improved and the appearance of the vehicle can be substantially guaranteed.

  Here, a second embodiment of the windshield device for a vehicle according to the present invention will be described. In addition, the same code | symbol is used for the member substantially the same as the above-mentioned embodiment or corresponding. 11 and 12 show the internal structure of the vehicle body cover at the front portion of the vehicle in the second embodiment. 11 shows the state when the wind screen 113 is raised, and FIG. 12 shows the state when the wind screen 113 is lowered.

  Particularly in the second embodiment, when the wind screen 113 is raised, the screen back side air passage 11 is closed above the air inlet 2 as shown in FIG. 11 or the cross sectional area of the screen back side air passage 10 is reduced. A protrusion 8 is provided. Since the protrusion 8 is formed of a flexible member, the protrusion 8 has flexibility. In this example, the protrusion 8 protrudes rearward on the back side of the cover 113B as shown in FIG. Further, the projecting piece 8 is formed so as to occupy a considerable width in the left-right direction with respect to the screen rear side air passage 11 as shown in FIG.

  On the other hand, in the front meter panel 116, as shown in FIG. 11 or FIG. 12, the screen rear side air passage 10 is blocked above the air inlet 2, or the cross sectional area of the screen rear side air passage 10 can be reduced. A piece 9 is provided. The projecting piece 9 has flexibility, and is projected forward on the front side (front side) of the front meter panel 116 as shown in FIG. The projecting piece 9 is also formed so as to occupy a considerable width in the left-right direction with respect to the screen back side ventilation path 10.

  In the second embodiment of the present invention, as described above, the wind screen 113 can close the screen back side air passage 11 or reduce its cross-sectional area above the air guide portion 1 as shown in FIG. A protruding piece 8 is provided.

  The protruding piece 8 acts as a weir for the traveling wind 10 that is about to flow into the screen back side ventilation path 11, and improves the air guiding effect to the wind guide portion 1 when the wind screen 113 is raised. it can. The wind screen 113 is lifted to bring the air guide section 1 into an open state, thereby making it easier for the traveling wind 10 to be taken in from the air guide section 1, while suppressing the inflow into the screen back side air passage 11. The inflow effect to the wind guide portion 1 can be promoted more effectively. That is, the traveling wind 10 can be taken in more efficiently from the wind guide portion 1.

Further, the projecting piece 8 is provided on the rear surface of the cover 113B of the wind screen 113.
By providing the projecting piece 8 at a position hidden by the cover 113B which is a non-transparent member, the projecting piece 8 can be prevented from appearing in the appearance, and the appearance can be improved also in this respect.

Further, the front meter panel 116 is provided with a projecting piece 9 that can close the screen back side air passage 11 or reduce its cross-sectional area above the air guide portion 1.
The projecting piece 9 serves as a weir with respect to the air flowing into the screen back side ventilation path 11. In this case as well, the effect of inducing air to the air guide portion 1 can be improved with the wind screen 113 raised.
