Description

Wind screen

Technical Field

The utility model relates to a windshield.

Background

Conventionally, there is a structure in which a windshield for suppressing the traveling wind from blowing to the driver is disposed in a front portion of a saddle-ride type vehicle. The windshield is formed to extend in a low-to-high manner, and the traveling wind is hard to reach the driver behind the windshield. Further, there is a windshield having a shape in which a rear upper portion is warped forward (see, for example, japanese patent No. 4306890). According to this windshield, traveling wind flowing along the front surface of the windshield can be dispersed rearward and upward at the upper end edge, and thus traveling wind blowing on the driver can be further reduced.

In a vehicle provided with a windshield, negative pressure is generated in a space behind the windshield during traveling, and back pressure (pressure from the rear toward the front) acting on an occupant is increased, which may deteriorate comfort of the occupant. Therefore, the following structure is known: an opening is provided in the windshield, and the traveling wind is introduced into the space behind the windshield through the opening, thereby suppressing the generation of negative pressure (see, for example, japanese patent No. 4306890 and japanese patent No. 6129888).

SUMMERY OF THE UTILITY MODEL

However, when negative pressure is generated in the space behind the windshield, traveling wind flowing along the front surface of the windshield may be drawn behind the windshield and may blow on the driver. In such a viewpoint, even if the opening is provided in the damper, negative pressure is generated in the space behind the damper, and therefore there is room for improvement in the structure of the damper.

The scheme of the utility model provides a windshield with excellent windproof effect.

The utility model discloses a windshield setting of scheme is in the front portion of vehicle and the preceding low back highland extends, and it possesses: an upper portion including an upper end edge and being warped forward; a recess formed in the front surface at a position lower than the upper portion; and an opening portion that opens to an inside of the recess portion and introduces air into a space rearward, wherein the recess portion includes: a lower wall portion disposed below the opening portion; and a rear wall portion that forms a portion between the lower wall portion and the opening portion and extends at a larger inclination angle than the lower wall portion with respect to a front-rear direction of the vehicle.

According to the utility model discloses a scheme can make the wind of traveling that flows along the front surface of windshield at the upper portion of windshield orientation top, consequently can make the wind of traveling escape to the back upper place of windshield and reduce the wind of traveling that blows the driver at the last edge of windshield.

Among the traveling wind flowing along the front surface of the windshield, the traveling wind flowing into the recess from the front lower portion of the recess flows along the lower wall portion, then flows along the inner wall portion, and flows into the opening portion. Since the inner wall portion extends at a larger inclination angle with respect to the front-rear direction than the under wall portion, the traveling wind flowing along the under wall portion can be directed upward. This makes it possible to direct the traveling wind flowing into the opening in the direction along the rear surface of the portion of the windshield adjacent to the opening from above. Thus, the traveling wind introduced into the space behind the windshield from the opening portion flows along the rear surface of the windshield, and joins the traveling wind flowing along the front surface of the windshield at the rear upper side of the windshield.

Therefore, the traveling wind flowing along the front surface of the windshield can be prevented from being drawn rearward of the windshield by the negative pressure and blowing to the driver.

With the above, a windshield having an excellent wind-proof effect can be provided.

In the windshield described above, the inner wall portion may be formed larger than the lower wall portion in the vehicle width direction.

According to this configuration, the increase in the traveling wind is realized by the back wall portion wider than the width of the lower wall portion, and the flow velocity of the traveling wind along the lower wall portion narrower than the width of the back wall portion is increased at the upstream side of the back wall portion, whereby the flow velocity in the entire recess can be increased. Thus, the flow rate of the traveling wind flowing into the opening after flowing along the back wall portion can be secured much more than in a structure in which the back wall portion is formed smaller in the vehicle width direction than the lower wall portion. Therefore, the traveling wind flowing along the front surface of the windshield can be prevented from being drawn rearward of the windshield by the negative pressure and blowing to the driver.

The windshield may include: a contraction portion that contracts in a vehicle width direction when viewed from the front of the vehicle; and a fixing portion that is fixed to the vehicle, wherein the fixing portion is provided so as to vertically sandwich a narrow portion of the constricted portion, the narrow portion having the narrowest width in the vehicle width direction.

According to this configuration, the windshield is disposed so that the constricted portion is positioned between the handles in a front view, and thus, the traveling wind disturbed at the side edge of the windshield can be prevented from blowing on the hand of the driver gripping the handles. Therefore, the reduction of the steering performance due to the installation of the windshield can be suppressed. Further, since the windshield is fixed to the vehicle on both upper and lower sides of the narrow portion that is easily bent, the rigidity of the windshield can be ensured.

In the windshield described above, the fixing portion may be provided so as to vertically sandwich a portion of the windshield having the widest width in the vehicle width direction.

According to this configuration, since the narrow portion of the windshield and the portion having the widest width in the vehicle width direction are sandwiched vertically by the fixing portions, the portion that is easily bent and the portion that receives a large area of traveling wind can be sandwiched by the common fixing portions.

The windshield may include a peripheral edge portion surrounding the recess, and the back wall portion may extend at an inclination angle greater than or equal to an inclination angle of an upper portion of the peripheral edge portion with respect to the front-rear direction.

According to this configuration, since the traveling wind flowing along the inner wall portion is directed in the surface direction along the rear surface in the upper portion of the peripheral edge portion of the windshield, the traveling wind introduced into the space behind the windshield from the opening portion can be smoothly made to flow along the rear surface of the windshield.

According to the utility model discloses a scheme can provide the windshield that has excellent windproof effect.

The center tunnel 42 extends rearward from the rear portion of the front body cover 41 in the vehicle width center C (see fig. 3) of the vehicle, and covers the down frames 22 and the sub-frames 24 from the side and above. The bottom plate 43 extends rearward from the lower end portion of the front body cover 41 in both side directions of the center tunnel 42, and covers the lower frame 23 from above. The bottom plate 43 constitutes the bottom step plate 12. The rear body cover 44 is connected to a rear end of the center tunnel 42 and a rear end of the floor 43, and covers the rear frame 25 below the seat 11. The bottom cover 45 is disposed below the center tunnel 42 and the bottom plate 43, and covers the lower frame 23 from below.

Next, the structure of the vehicle front portion will be described in detail.

The front portion of the vehicle is provided with a meter 50 disposed in front of the handle bar 34, a meter visor 51 covering the meter 50 from the front upper side, and a windshield 60 disposed above the meter visor 51. The meter visor 51 protrudes rearward and upward from the front of the meter 50. The upper surface 52 of the meter visor 51 extends upward from the front end toward the rear end of the meter visor 51. The windshield 60 is formed in a thin plate shape by a transparent resin material. The windshield 60 shields the traveling wind toward the driver during forward traveling of the motorcycle 1.

As shown in fig. 2, the damper 60 is fixed to a movable mechanism 53 that supports the damper 60 on the meter visor 51 so that the height thereof can be adjusted. In the present embodiment, the damper 60 is movable in both directions between a lower limit position indicated by a two-dot chain line and an upper limit position indicated by a solid line. The windshield 60 is disposed along the upper surface 52 of the meter visor 51. The windshield 60 as a whole extends low in the front and high in the rear. The windshield 60 extends rearward and upward from a portion facing the upper surface 52 of the meter visor 51 with respect to the meter visor 51.

Fig. 3 is a front view of a windshield showing an embodiment.

As shown in fig. 2 and 3, the windshield 60 is curved so as to extend rearward from a portion located at the vehicle width center C of the vehicle toward the outside in the vehicle width direction. The dampers 60 are formed symmetrically with respect to the vehicle width center C.

As shown in fig. 3, the windshield 60 includes a constricted portion 61 that is constricted in the vehicle width direction in a front view seen from the front of the vehicle, an upper portion 62 that is adjacent to the constricted portion 61 at the rear upper side and includes an upper end edge 60u of the windshield 60, and a lower portion 63 that is adjacent to the constricted portion 61 at the front lower side and includes a lower end edge 60l of the windshield 60. That is, the constricted portion 61 is provided at the middle in the vertical direction in the windshield 60. The constricted portion 61 is disposed on the vehicle width direction inner side of the handlebar 34 (see fig. 1) in front view. In the constricted portion 61, the entire side edges on both sides in the vehicle width direction extend so as to be recessed inward in the vehicle width direction. The upper portion 62 is tapered upward so that the side edges on both sides in the vehicle width direction approach the vehicle width center C as they face upward. An upper end edge of the upper portion 62 (an upper end edge 60u of the windshield 60) extends substantially linearly in the vehicle width direction in front view. The lower portion 63 tapers downward such that the side edges on both sides in the vehicle width direction approach the vehicle width center C as the side edges face downward. The lower end edge of the lower portion 63 (the lower end edge 60l of the windshield 60) extends substantially linearly in the vehicle width direction in front view.

As shown in fig. 4, the upper portion 62 of the damper 60 is warped forward. Specifically, the upper half portion 62U of the upper portion 62 extends at least at the vehicle width center C at a larger inclination angle with respect to the front-rear direction than the lower half portion 62L of the upper portion 62 as viewed in the vehicle width direction. The lower half 62L of the upper part 62 extends at the same inclination angle as the contracted part 61 with respect to the front-rear direction.

As shown in fig. 3, the windshield 60 has a fixing portion 65 fixed to the vehicle. The fixed portion 65 is coupled to the movable mechanism 53 (see fig. 2). The fixed portion 65 is fastened and coupled to the movable mechanism 53. The fixing portions 65 are provided in a distributed manner in the vehicle width direction and the vertical direction.

In the present embodiment, the fixing portion 65 is provided at two upper and lower positions on each of the left and right sides with respect to the vehicle width center C. Of the fixing portions 65, an upper pair of fixing portions 65A are formed in the constricted portion 61. More specifically, the pair of upper fixing portions 65A are formed in the upper portion of the narrow portion 61a of the constricted portion 61, which is the narrowest in width in the vehicle width direction. Of the fixing portions 65, a lower pair of fixing portions 65B are formed in the lower portion 63 of the windshield 60. Thus, the fixing portion 65 is provided to sandwich the narrow portion 61a of the constricted portion 61 from above and below. The pair of upper fixing portions 65A are provided in a portion of the windshield 60 above the portion having the widest width in the vehicle width direction. The portion of the windshield 60 having the widest width in the vehicle width direction is the lower end portion of the constricted portion 61. Thus, the fixing portion 65 is provided so as to vertically sandwich the portion of the windshield 60 having the widest width in the vehicle width direction.

The damper 60 is formed with a recess 70 and an opening 80. The recess 70 and the opening 80 are formed in the constricted portion 61. The recess 70 and the opening 80 are formed in the vehicle width center C. Recess 70 is formed in front surface 60f of windshield 60. The recess 70 is formed integrally in the upper portion of the constricted portion 61 with respect to the narrow portion 61 a. The specific shape of the recess 70 will be described later.

As shown in fig. 3 and 4, the opening 80 penetrates the damper 60. The opening 80 introduces air (traveling wind) into a space behind the windshield 60. The opening 80 is located above all the fixing portions 65. The opening 80 is formed in the constricted portion 61 above the narrow portion 61 a. The opening 80 is opened in a front surface 60f of the windshield 60 in a direction inclined forward with respect to the vehicle width direction and the vertical direction. In the present embodiment, the opening 80 is opened in the front surface 60f of the windshield 60 in a direction orthogonal to the vehicle width direction and slightly inclined downward from the front. The opening 80 opens from the rear upper side to the inside of the recess 70. The upper portion of the opening edge 80a of the opening 80 coincides with the upper portion of the peripheral edge 70a of the recess 70. The opening 80 is formed in a rectangular shape larger than the vertical direction in the vehicle width direction in front view.

The recess 70 will be described in detail.

The recess 70 includes a lower wall 71, a back wall 72, and a pair of left and right side walls 73. The lower wall portion 71 is disposed at a position forward of the opening 80 with a space from the opening 80. The lower wall portion 71 is disposed between the pair of upper fixing portions 65A in front view. The lower wall portion 71 extends rearward and upward from a lower portion of the peripheral edge 70a of the recess 70. The rear end edge 71r of the lower wall portion 71 extends in the vehicle width direction in front view. The inner wall 72 forms a portion between the lower wall 71 and the opening 80. The inner wall portion 72 is arranged at an interval over the entire circumference of the peripheral edge 70a of the recess 70. That is, the back wall portion 72 is the bottom of the recess 70. The inner wall portion 72 extends rearward and upward from the rear end edge 71r of the lower wall portion 71. The inner wall portion 72 extends at a larger inclination angle with respect to the front-rear direction than the lower wall portion 71. The back wall portion 72 extends in parallel with an upper portion of the peripheral edge portion 64 of the recess 70 with respect to the front-rear direction. In the present embodiment, the back wall portion 72 extends parallel to the entire peripheral edge portion 64 of the recess 70 with respect to the front-rear direction. The peripheral edge portion 64 of the recess 70 includes a peripheral edge portion 70a of the recess 70 and extends to surround the recess 70. The upper end edge 72u (rear end edge) of the rear wall portion 72 is formed below the opening edge 80a of the opening 80, and defines the opening 80 from below.

The lower wall portion 71 and the rear wall portion 72 are formed so as to gradually increase in the vehicle width direction from below upward in front view. In the present embodiment, the back wall portion 72 gradually increases in the vehicle width direction continuously from the lower wall portion 71. Thus, the inner wall portion 72 is formed larger than the lower wall portion 71 in the vehicle width direction.

The side wall portion 73 is disposed so as to sandwich the lower wall portion 71 and the rear wall portion 72 from the outside in the vehicle width direction. The side wall portion 73 extends rearward from a side portion in the vehicle width direction of the peripheral edge 70a of the recess 70. The upper end edge 73u of the side wall portion 73 forms a vehicle width direction side portion of the opening edge 80a of the opening portion 80, and defines the opening portion 80 from the outside in the vehicle width direction. That is, the opening 80 is a through hole that opens to the rear upper portion of the recess 70 recessed rearward and downward in the front surface 60f of the windshield 60.

As described above, the windshield 60 of the motorcycle 1 of the present embodiment includes the upper portion 62, and the upper portion 62 includes the upper end edge 60u of the windshield 60 and is warped forward. According to this configuration, since the traveling wind flowing along front surface 60f of windshield 60 can be directed upward, the traveling wind escapes to the rear upper side of windshield 60 at upper end edge 60u of windshield 60, and the traveling wind blowing on the driver can be reduced.

In the present embodiment, the damper 60 includes: a recess 70 formed in the front surface 60f of the windshield 60 below the upper portion 62; and an opening 80 that opens to the inside of the recess 70. The recess 70 has: a lower wall portion 71 disposed below the opening 80; and a back wall portion 72 that forms a portion between the lower wall portion 71 and the opening 80 and extends at a larger inclination angle with respect to the front-rear direction than the lower wall portion 71. According to this configuration, among the traveling wind flowing along the front surface 60f of the windshield 60, the traveling wind flowing into the recess 70 from the front-lower direction of the recess 70 flows along the lower wall portion 71, then flows along the inner wall portion 72, and flows into the opening 80. Since the inner wall portion 72 extends at a larger inclination angle with respect to the front-rear direction than the lower wall portion 71, the traveling wind flowing along the lower wall portion 71 can be directed upward. This allows the traveling wind flowing into the opening 80 to be directed along the surface direction of the rear surface of the portion of the windshield 60 adjacent to the opening 80 from above. Therefore, the traveling wind introduced from the opening 80 into the space behind the windshield 60 flows along the rear surface of the windshield 60, and joins the traveling wind flowing along the front surface 60f of the windshield 60 at the rear upper side of the windshield 60. Therefore, the traveling wind flowing along the front surface 60f of the windshield 60 can be suppressed from being drawn rearward of the windshield 60 by the negative pressure and being blown to the driver.

With the above, the windshield 60 having an excellent wind-proof effect can be provided.

The inner wall portion 72 is formed larger than the lower wall portion 71 in the vehicle width direction. According to this configuration, the increase in the traveling wind is realized by the back wall portion 72 having a width wider than that of the lower wall portion 71, and the flow velocity of the traveling wind along the lower wall portion 71 having a width narrower than that of the back wall portion 72 is increased at a position upstream of the back wall portion 72, thereby increasing the flow velocity in the entire recess 70. Thus, compared to a structure in which the inner wall portion is formed smaller in the vehicle width direction than the lower wall portion, the flow rate of the traveling wind flowing into the opening 80 after flowing along the inner wall portion 72 can be secured much more. Therefore, the traveling wind flowing along the front surface 60f of the windshield 60 can be prevented from being drawn rearward of the windshield 60 by the negative pressure and blowing on the driver.

The fixing portion 65 is provided so as to vertically sandwich the narrow portion 61a of the constricted portion 61. According to this configuration, by disposing damper 60 such that constricted portion 61 is positioned between handlebars 34 in a front view, it is possible to suppress the traveling wind that is disturbed at the side edge of damper 60 from blowing on the hand of the driver gripping handlebar 34. Therefore, the reduction in steering performance due to the provision of the damper 60 can be suppressed. Further, since the damper 60 is fixed to the vehicle on both upper and lower sides across the narrow portion 61a that is easily bent, the rigidity of the damper 60 can be ensured.

Further, since the opening 80 is located above the fixing portion 65, the traveling wind flowing into the opening 80 can be prevented from blowing on the movable mechanism 53 supporting the windshield 60 behind the windshield 60. Therefore, the traveling wind introduced from the opening 80 into the space behind the windshield 60 can smoothly flow along the rear surface of the windshield 60.

The fixing portion 65 is provided so as to vertically sandwich a portion of the windshield 60 having the widest width in the vehicle width direction. According to this configuration, since the narrow portion 61a of the windshield 60 and the portion having the widest width in the vehicle width direction are sandwiched vertically by the fixing portions 65, the portion that is easily bent and the portion that receives a large area of traveling wind can be sandwiched by the common fixing portion 65.

The back wall portion 72 extends in parallel with an upper portion of the peripheral edge portion 64 of the recess 70 with respect to the front-rear direction. According to this configuration, since the traveling wind flowing along the inner wall portion 72 is directed in the surface direction along the rear surface of the upper portion of the peripheral edge portion 64 of the recess 70 in the windshield 60, the traveling wind introduced into the space behind the windshield 60 from the opening portion 80 can be smoothly flowed along the rear surface of the windshield 60.

The present invention can be applied to all straddle-type vehicles in which a driver rides a vehicle body straddling the vehicle body. That is, the present invention can be applied not only to a scooter type motorcycle but also to a motorcycle or a motor tricycle without a bottom pedal, or a motorcycle such as a truck or an ATV (All Terrain Vehicle). The present invention is not limited to the above-described embodiments described with reference to the drawings, and various modifications are considered within the technical scope thereof.

In the above embodiment, the opening 80 and the recess 70 are formed in the vehicle width center C of the vehicle, but the present invention is not limited to this configuration. That is, the opening and the recess may be formed at positions offset from the center of the vehicle width.

In the above embodiment, the back wall portion 72 extends substantially parallel to the upper portion of the peripheral edge portion 64 of the recess 70 with respect to the front-rear direction, but the configuration is not limited thereto. The inner wall portion may extend at an inclination angle larger than an inclination angle of an upper portion of the peripheral edge portion of the recess portion with respect to the front-rear direction. According to this configuration, since the traveling wind passing through the opening portion can be directed toward the rear surface of the windshield, the traveling wind can be smoothly made to flow along the rear surface of the windshield.

In the above embodiment, the opening 80 is opened in the front surface 60f of the windshield 60 in a direction inclined slightly downward from the front, but the configuration is not limited thereto. The opening portion may be opened in a direction inclined forward, for example, in a direction of a surface of the front surface at a lower portion, which is a portion adjacent to the opening portion from above in the windshield. That is, the opening may be open forward or may be open in a direction slightly inclined upward from the front.

In addition, the components in the above-described embodiments may be replaced with known components as appropriate without departing from the scope of the present invention.
