[0057] The straddle-type vehicle display device 100 of this embodiment is provided in a straddle-type vehicle such as a so-called moped or a scooter. Figure 1 As shown in Figure 1 The main part of the enlarged view is in Figure 2 As shown in Figure 2 The cross-sectional view of section AA is shown in Figure 3 In addition, Figure 1 The arrow direction stereogram observed from the B direction is Figure 4 As shown in the figure, the side view in the direction of the arrow viewed from the C direction is Figure 5 As shown in the figure, the main view in the direction of the arrow viewed from the D direction is Figure 6 As shown in Figure 6 The top view in the direction of the arrow E is Figure 7 Shown in.

[0058] exist Figure 1 to Figure 7 The straddle-type vehicle has a handlebar tube 5 (handlebar steering axis) extending substantially horizontally along the vehicle width direction at the front end of the vehicle body frame, and a pair of left and right handlebars 6L, 6R provided at the left and right ends of the handlebar tube 5, respectively.

[0059] <Overall Structure of Display Device>

[0060] The display device 100 for a straddle-type vehicle includes: a front cover 1 that covers the front and upper sides of a handlebar tube 5 and is formed of a seamless single member; a rear cover 2 that covers the rear side of the handlebar tube 5; a lamp body 4 that is disposed on the handlebar tube 5 side of a front region 1F (described later) of the front cover 1; and a meter section 3 that is disposed on the handlebar tube 5 side of a rear region 1B (described later) of the front cover 1. The handlebar tube 5 passes between the meter section 3 and the lamp body 4.

[0061] <Front cover>

[0062] The front cover 1 is made of a transparent or atomized material and is fixed to the handlebar tube 5 via a fixing member (not shown). The front cover 1 includes a front region (front end portion) 1F, a rear region 1B (rear end portion), an upper region 1U between the front region 1F and the rear region 1B, a lower region 1L connected to the lower portion of the front region 1F, and a lowermost region 1D connected to the lower portion of the lower region 1L.

[0063] In the area (front area 1F) corresponding to the lamp body 4 in the front cover 1, for example, a first transmission portion 11 formed of a light-transmitting synthetic resin and having a predetermined transmittance is provided, and in the area (rear area 1B) corresponding to the meter portion 3, for example, a second transmission portion 12 formed of a light-transmitting synthetic resin and having a predetermined transmittance is provided. The portion other than the first transmission portion 11 and the second transmission portion 12 of the front cover 1 is formed by, for example, two-color molding of a light-shielding synthetic resin, and light-shielding is performed by black coating, film printing, etc., and the shape / appearance of the meter portion 3 and the lamp body 4 is formed by this light-shielding. In other words, the meter portion 3 and the lamp body 4 become an integrated structure through the front cover 1, thereby, as shown in FIG. Figure 1 and Figure 2 As shown, a brand new design with a new and beautiful appearance is achieved.

[0064] At this time, if Figure 3 As shown, the upper region 1U, the front region 1F, and the lower region 1L of the front cover 1 cover, for example, a space of an angle α1 (for example, an appropriate value of α1=150° or more and 210° or less) on the front side with the front edge P of the handlebar tube 5 as a reference. In addition, by forming the first transmission portion 11 in a range of approximately 60° on the front end side, a new appearance can be provided. In addition, the rear region 1B of the front cover 1 covers, for example, a space of an angle α2 (for example, an appropriate value of α1=60° or more and 120° or less) on the rear side with the front edge P of the handlebar tube 5 as a reference.

[0065] <Transmission section>

[0066] like Figure 3 As shown, the cross-sectional shape of the first transmission portion 11 is a curved surface, and the cross-sectional shape of the second transmission portion 12 is a substantially flat surface (eg, Figure 4 In addition, the wall thickness (first wall thickness) t1 of the first transmission portion 11 is greater than the wall thickness (second wall thickness) t2 of the second transmission portion 12. Furthermore, the outer surface 1a of the front cover 1 is coplanar with the outer surface 11a of the first transmission portion 11 and the outer surface 12a of the second transmission portion 12.

[0067] <Instrumentation Department>

[0068] Instrument 3 Figure 3 As shown, the front cover 1 includes various meters 31 such as LED type meters, LCD type meters, and pointer type meters; a mounting plate 32 on which these various meters 31 are mounted and which is composed of a hard circuit substrate, etc.; and a bracket 33 for fixing the mounting plate 32 to the front cover 1. The various meters 31 display the functions of general meters, that is, operation lights such as a speedometer and a rotation indicator (engine speed), warning lights, etc. In addition, the transmission part 12 of the front cover 1 also serves as a protective lens for the meter part 3.

[0069] <Lamp body>

[0070] The lamp body 4 includes: left and right lighting parts 4L and 4R, which are respectively arranged at the two ends in the vehicle width direction and can function as vehicle width lights and direction indicators; and a central lighting part 4M, which is arranged between the left lighting part 4L and the right lighting part 4R and plays a decorative lighting function other than the vehicle width lights and direction indicators (described later). In addition, corresponding to it, the first transmission part 11 is as shown in FIG. Figure 2 As shown in FIG. 1 and FIG. 2 , the left transmissive portion 11L transmits the illumination light of the left illumination portion 4L; the central transmissive portion 11M transmits the illumination light of the central illumination portion 4M; the left transmissive portion 11L transmits the illumination light of the left illumination portion 4L; and the right transmissive portion 11R transmits the illumination light of the right illumination portion 4R. The illumination portions 4L, 4R, and 4M are respectively as shown in FIG. Figure 3 As shown, the lamp body 4 includes a light source 41 such as an LED or a hard circuit board, an optical component 42, and a bracket 43 for fixing the light source 41 to the front housing 1. The transmissive portions 11L, 11M, and 11R also function as protective lenses for the lamp body 4.

[0071] The left and right lighting units 4L and 4R have a light emitting range of approximately 200° in the up / down direction in a vertical cross section, and in this example, operate in the following three modes.

[0072] The first mode is a case where the two functions of the vehicle width lamp and the direction indicator are combined. In this case, the left and right lighting units 4L and 4R emit reddish-brown light to notify the outside of the vehicle of the presence of the straddle-type vehicle (vehicle width lamp) or the direction of travel (direction indicator). In addition, when functioning as a vehicle width lamp, it is fully lit, and when functioning as a direction indicator, it flashes.

[0073] The second mode is a case where the vehicle functions only as a direction indicator, in which case the left and right lighting units 4L and 4R flash reddish brown to notify the outside of the vehicle of the direction of travel.

[0074] The third mode is a case where the vehicle functions only as the vehicle width lamp. In this case, the left and right lighting units 4L and 4R emit white light to notify the outside of the vehicle of the presence of the straddle-type vehicle.

[0075] The central lighting unit 4M is configured to perform decorative lighting of a dot pattern in this example, and has a light emitting range of approximately 180° in the vertical cross section along the up / down direction. The central lighting unit 4M performs a welcoming action to the user by emitting white light and displaying an animation when the ignition of the straddle-type vehicle is turned on. During normal driving, the central lighting unit 4M is entirely lit in white, and functions as a design feature of the straddle-type vehicle.

[0076] <Wiring structure>

[0077] The meter unit 3 has a microcomputer (control unit, not shown) for controlling the display of the various meters 31. The microcomputer is connected to an ECU (not shown) of the straddle-type vehicle via a signal wiring S30 (see Figure 3 ) is connected. In addition, at this time, the lamp body 4 and the microcomputer of the meter part 3 are connected through the signal wiring S34 (refer to Figure 3 ) is connected, and the lamp body 4 is controlled by a microcomputer via the signal wiring S34.

[0078] <Effects of Implementation Methods>

[0079] As described above, in the present embodiment, the front cover 1 covering at least the front side and the upper side of the handlebar tube 5 is formed of a seamless single member, and the lamp body 4 and the meter part 3 are respectively arranged on the handlebar tube 5 side of the front region 1F and the rear region 1B of the front cover 1. Thus, since the lamp body 4 and the meter part 3 can be assembled to the front cover 1 and formed integrally, the manufacturing process can be simplified and the cost can be reduced. In addition, the dustproof and waterproof properties can be improved by the integrated structure.

[0080] Furthermore, since the first transmission portion 11 and the second transmission portion 12 are integrally included in the front cover 1, they can also function as protective lenses for the lamp body 4 and the meter portion 3, thereby reducing the number of components and thus reducing costs.

[0081] Furthermore, since the front cover 1 extends forward and backward without any joints between components, rainwater is unlikely to enter the internal space where the handlebar tube 5 and the like are accommodated from above, and the waterproof performance can be improved.

[0082] In this embodiment, in particular, the first transmission portion 11 and the second transmission portion 12 are formed flush with the surrounding front cover 1 to form a structure without steps. This can increase the sense of unity.

[0083] In this embodiment, in particular, the cross-sectional shape of the first transmissive portion 11 for the lamp body 4 is curved, thereby ensuring lighting performance that reaches far away. In addition, the cross-sectional shape of the second transmissive portion 12 for the meter portion 3 is roughly flat, thereby ensuring good visual observation.

[0084] In this embodiment, in particular, by making the thickness t1 of the first transmission portion 11 larger than the thickness t2 of the second transmission portion 12 , it is possible to prevent damage with greater strength even when the vehicle collides with a small stone during travel.

[0085] In the present embodiment, in particular, both the display control of the meter section 3 and the light emission control of the lamp body 4 are executed by the microcomputer provided in the meter section 3. This simplifies the structure and facilitates the control process.

[0086] In addition, in this embodiment, in particular, the lamp body 4 includes a left lighting unit 4L, a right lighting unit 4R, and a center lighting unit 4M. Thus, the left and right lighting units 4L and 4R can function as vehicle width lamps / direction indicators, which are essential functions of a straddle-type vehicle, and the center lighting unit 4M can function as decorative lighting such as animation, thereby improving commercial properties.
