[0006] Problem that the invention aims to solve

[0007] In the headlamp unit described in Patent Document 1, since a light source for emitting a high beam and a low beam is included in one outer lens, the size of the outer lens is large.

[0008] The present invention provides a headlamp unit having a compact outer lens and a saddle-ride type vehicle having such a headlamp unit.

[0009] Solutions for solving problems

[0010] The present disclosure provides a headlamp unit, wherein:

[0011] The headlamp unit has:

[0012] Two low beam outer lens portions, the two low beam outer lens portions are arranged side by side and spaced apart from each other so as to allow the low beam to pass forward; and

[0013] A high beam outer lens portion is arranged on the right side relative to the left end of the low beam outer lens portion arranged on the left side, and is arranged on the left side relative to the right end of the low beam outer lens portion arranged on the right side, and is arranged at a distance above or below the two low beam outer lens portions to allow the high beam to pass forward.

[0014] According to the headlamp unit disclosed in the present invention, a high beam outer lens portion is arranged between the left and right low beam outer lens portions in the left-right direction, and is arranged at a distance above or below the low beam outer lens portion, and the lens portion for the low beam is different from the lens portion for the high beam. Therefore, it is not necessary to accommodate light sources for irradiating the high beam and the low beam in one lens portion, so the size of each outer lens portion can be reduced.

[0021] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In order to facilitate understanding, a part of the drawings may be simplified.

[0022] Figure 1 1 is a front side view of a saddle-type vehicle 100 equipped with the headlamp unit 1 of the present embodiment. In this specification, "front", "rear", "left" and "right" refer to the front, rear, left and right directions viewed by a driver riding on the saddle-type vehicle 100. In addition, the height direction of the saddle-type vehicle 100 is regarded as the up-down direction. For example, the left-right direction corresponds to the vehicle width direction of the saddle-type vehicle 100.

[0023] The headlamp unit 1 of the present embodiment is a lamp unit for illuminating the front of the saddle-type vehicle 100, and is mounted on the front side of the saddle-type vehicle 100. In addition, in the saddle-type vehicle 100, an engine as a driving source for rotating the driving wheels of the saddle-type vehicle 100 and a frame supporting the engine are provided behind the headlamp unit 1. The engine is provided with a radiator 102 for cooling the heat generated by the engine with a refrigerant behind the headlamp unit 1. The saddle-type vehicle 100 is also provided with a shroud for guiding the running wind to the radiator 102.

[0024] The headlight unit 1 of the present embodiment is supported by a bracket that supports the front fork. The headlight unit 1 is angularly displaced relative to the frame together with the front fork as the handlebar is turned. The headlight unit 1 of the present embodiment can be arranged closer to the front fork than when it is fixed to the frame. As a result, the front-to-back dimensions of the headlight unit 1 can be miniaturized and lightweight. The shape of the headlight unit is sometimes preferably smaller. In addition, the front end of the headlight unit 1 of the present embodiment is located rearward relative to the front wheel.

[0025] The size of the headlight unit 1 in the vertical direction gradually increases from the front end toward the rear. In addition, the size of the headlight unit 1 in the horizontal direction gradually increases from the front end toward the rear (see Figure 3 ).

[0026] Figure 2 1 is a front view of a headlamp unit 1. The headlamp unit 1 includes a headlamp 2 and an upper cowl 3 covering the headlamp 2. An outer lens 12 for transmitting light forward is mounted on the headlamp 2. The material of the outer lens 12 is a light-transmitting material, specifically, a transparent resin. The upper cowl 3 is opaque and covers the area of ​​the headlamp 2 except for the outer lens 12.

[0027] The outer lens 12 has three parts. Specifically, the outer lens 12 has two low beam outer lens parts 12a for transmitting low beam to the front and one high beam outer lens part 12b for transmitting high beam to the front. Each low beam outer lens part 12a and high beam outer lens part 12b are independently formed and arranged at intervals from each other.

[0028] The low beam is a headlamp for meeting other vehicles, and is used to illuminate the front of the vehicle, for example, to identify traffic obstacles at a distance of 40 meters ahead at night. The high beam is a headlamp for driving, and is used to illuminate the front of the vehicle, for example, to identify traffic obstacles at a distance of 100 meters ahead at night. In this way, the illumination direction of the high beam is set so that obstacles farther than the low beam can be identified. When driving, the low beam is always on, and the high beam is appropriately lit by the driver's operation.

[0029] The two low beam outer lens portions 12a are arranged on the left and right, respectively, and are arranged symmetrically with respect to the left and right centers C1 of the headlamp 2 (the center line passing through the midpoints of the left and right ends of the front housing 10 constituting the headlamp 2) at intervals in the left and right directions. The two low beam outer lens portions 12a are arranged passing through the upper and lower centers C2 of the headlamp 2 (the center line passing through the midpoints of the upper and lower ends of the front housing 10). In other words, the upper and lower centers C2 of the headlamp are located between the upper edges 12a1, 12a2 and the lower edge 12a4 of the low beam outer lens portions 12a. When viewed from the front, the low beam outer lens portion 12a has a first upper edge 12a1 that is inclined upward from the inside to the outside in the left and right directions. In addition, the lower edge 12a4 of the low beam outer lens portion 12a is inclined upward from the inside to the outside in the left and right directions.

[0030] The high beam outer lens portion 12b is located between the two low beam outer lens portions 12a in the left-right direction. The high beam outer lens portion 12b is disposed symmetrically with respect to the left-right center C1 of the headlamp 2. Specifically, the high beam outer lens portion 12b is disposed on the right side relative to the left end of the low beam outer lens portion 12a disposed on the left side, and is disposed on the left side relative to the right end of the low beam outer lens portion 12a disposed on the right side, and is disposed at a distance below the lower ends of the two low beam outer lens portions 12a.

[0031] More specifically, the upper edge 12b1 of the high beam outer lens portion 12b is located on the right side relative to the right end of the lower edge 12a4 of the low beam outer lens portion 12a disposed on the left side, and is located on the left side relative to the left end of the lower edge 12a4 of the low beam outer lens portion 12a disposed on the right side. Furthermore, the upper edge 12b1 of the high beam outer lens portion 12b is located below the lower edges 12a4 of the two low beam outer lens portions 12a.

[0032] In addition, the outer end of the high beam outer lens portion 12b in the left-right direction is located outside the left-right direction relative to the inner end of the low beam outer lens portion 12a in the left-right direction. That is, when viewed from above, the high beam outer lens portion 12b has a portion that overlaps with the two low beam outer lens portions 12a in the left-right direction. When viewed from the front, the upper edge 12b1 and the lower edge 12b4 of the high beam outer lens portion 12b extend parallel to the left-right direction.

[0033] The low beam outer lens portion 12a is roughly pentagonal when viewed from the front, and is formed by a first upper edge 12a1 on the left-right center C1 side of the headlight, a second upper edge 12a2 on the side opposite to the left-right center C1, a first side edge 12a3 on the side opposite to the left-right center C1, a lower edge 12a4 and a second side edge 12a5 on the left-right center C1 side.

[0034] The second side edge 12a5 is inclined upward from the outside in the left-right direction toward the inside. Therefore, the angle between the first upper edge 12a1 of the low beam outer lens portion 12a and the second side edge 12a5 is an acute angle. Therefore, the dimension in the up-down direction on the outside in the left-right direction (the distance in the up-down direction between the first upper edge 12a1 and the lower edge 12a4) is larger than the dimension in the up-down direction on the inside in the left-right direction of the low beam outer lens portion 12a (the distance in the up-down direction between the first upper edge 12a1 and the second side edge 12a5). In addition, an area is formed in the low beam outer lens portion 12a that is arranged outside in the left-right direction relative to the high beam outer lens portion 12b, and the dimension in the up-down direction of the area is larger than the dimension in the up-down direction of the high beam outer lens portion 12b. As a result, compared with the high beam outer lens portion 12b, the low beam outer lens portion 12a can easily irradiate light toward the outside in the left-right direction.

[0035] The high beam outer lens portion 12b is roughly hexagonal in front view, and is formed by the upper edge 12b1, two upper side edges 12b2, two lower side edges 12b3 and the lower edge 12b4. In addition, the midpoint of the upper edge 12b1 and the midpoint of the lower edge 12b4 are located at the left-right center C1, and the center position of the high beam outer lens portion 12b coincides with the left-right center C1. In this way, the high beam outer lens portion 12b is arranged close to the left-right center C1, so it is easier to irradiate light toward a relatively far area ahead in the driving direction compared with the low beam outer lens portion 12a.

[0036] The upper side edge 12b2 of the high beam outer lens portion 12b is inclined downward toward the left-right outer side, and its inclination direction is the same as the inclination direction of the second side edge 12a5 of the low beam outer lens portion 12a. By making these side edges 12b2 and 12a5 inclined in the same direction, it is easy to ensure the interval between the side edges 12b2 and 12a5 along the inclination direction, and it is easy to arrange the upper fairing 3 between the low beam outer lens portion 12a and the high beam outer lens portion 12b.

[0037] In a front view, the area of ​​the high-beam outer lens portion 12 b is smaller than the area of ​​each low-beam outer lens portion 12 a .

[0038] exist Figure 1 In the embodiment, the front end of the high beam outer lens portion 12b is arranged at the rear relative to the front end of the low beam outer lens portion 12a. In addition, the high beam outer lens portion 12b is inclined downward from the front end toward the rear, forming a so-called reverse inclined shape. Therefore, when the running wind of the riding type vehicle 100 collides with the high beam outer lens portion 12b, it is guided toward the rear and downward along the inclination of the high beam outer lens portion 12b. In this case, the running wind is guided toward the radiator 102 located behind and below the headlamp unit 1. Thereby, the running wind can be actively guided to the radiator 102.

[0039] The low beam outer lens portion 12a is also inclined downward from the front end toward the rear, forming a so-called reverse inclined shape. As a result, the low beam outer lens portion 12a can be made less conspicuous. In addition, when the running wind of the riding type vehicle 100 collides with the low beam outer lens portion 12a, it is guided downward and to the outside in the left and right directions along the inclination of the low beam outer lens portion 12a. Therefore, it is possible to prevent the running wind from flowing toward the top of the headlamp unit 1. Therefore, it is possible to suppress the running wind from flowing toward the driver along the upper surface of the headlamp.

[0040] Figure 3 This is a diagram showing the headlight unit 1 as viewed from obliquely above. Figure 3 In the embodiment of the present invention, the low beam outer lens portion 12a is inclined backward from the inner end in the left-right direction toward the outer end in the left-right direction. The headlamp 2 and the upper fairing 3 are also inclined backward from the inner end in the left-right direction toward the outer end in the left-right direction. In addition, the upper surface of the headlamp 2 and the upper fairing 3 is inclined upward from the front end toward the rear. Thus, the shape of the headlamp unit 1 of the saddle-type vehicle 100 can be made close to a streamline shape that guides the running wind backward.

[0041] The low beam outer lens portion 12a extends in the left-right up-down direction and the front-back up-down direction. In other words, a main inclined surface 12a6 is formed in the low beam outer lens portion 12a, and the main inclined surface 12a6 is inclined outward in the left-right direction from the front end toward the rear, and is inclined toward the rear from the upper edges 12a1 and 12a2 toward the bottom. The main inclined surface 12a6 is a flat surface with a larger area than the remaining surface of the surface constituting the low beam outer lens portion 12a. The main inclined surface 12a6 is the portion through which the low beam is transmitted.

[0042] The high beam outer lens portion 12b extends in the left-right and up-down directions. In other words, a main inclined surface 12b5 is formed in the high beam outer lens portion 12b, and the main inclined surface 12b5 extends in the left-right direction and is inclined downward and rearward from the upper edge 12b1. The main inclined surface 12b5 is a portion for the high beam to pass through.

[0043] exist Figure 2 In the figure, the upper cowl 3 includes a first upper cowl 30 covering an upper portion of the headlight 2 and a second upper cowl 31 covering a lower portion of the headlight 2 .

[0044] The first upper fairing 30 is disposed along the upper edges 12a1 and 12a2 of the low beam outer lens portion 12a, and the second upper fairing 31 is disposed along the side edges 12a3 and 12a5 and the lower edge 12a4 of the low beam outer lens portion 12a.

[0045] The front end of the first upper fairing 30 is located forward relative to the front end of the low beam outer lens portion 12a. Specifically, the front end of the first upper fairing 30 protrudes forward along the upper edges 12a1 and 12a2 of the low beam outer lens portion 12a. Thus, when the headlamp unit 1 is viewed from above, the low beam outer lens portion 12a can be prevented from being exposed.

[0046] like Figure 3 As shown, the second upper fairing 31 comprises: a first protrusion 31a which protrudes forward from the second side edge 12a5 of the low beam outer lens portion 12a along the upper edge 12b1 of the high beam outer lens portion 12b; and a pair of left and right second protrusions 31b which protrude forward from the lower edge 12a4 of the low beam outer lens portion 12a along the left and right side edges 12b2, 12b3 of the high beam outer lens portion 12b.

[0047] The first protrusion 31a covers the high beam outer lens portion 12b from above when viewed from above, and the second protrusion 31b covers the high beam outer lens portion 12b from the side when viewed from the side. In other words, the high beam outer lens portion 12b is arranged at the rear relative to the front end of the second upper fairing 31. Specifically, the high beam outer lens portion 12b is arranged at the rear relative to the first protrusion 31a. In addition, the high beam outer lens portion 12b is arranged at the rear relative to the second protrusions 31b on the left and right. Thus, the upper fairing 3 is used to prevent the high beam outer lens portion 12b from being exposed when viewed from above or from the side.

[0048] The first protrusion 31a and the second protrusion 31b of the present embodiment protrude forward relative to the low beam outer lens portion 12a. Thus, compared with the case where the first protrusion 31a and the second protrusion 31b do not protrude relative to the low beam outer lens portion 12a, it is possible to further suppress exposure of the high beam outer lens portion 12b. For example, it is possible to prevent external light such as sunlight and street lights from easily intruding into the high beam outer lens portion 12b.

[0049] The portion of the second upper fairing 31 covering the area between the second side edge 12a5 of the low beam outer lens portion 12a and the upper side edge 12b2 of the high beam outer lens portion 12b extends along the side edges 12b2 and 12a5. Thus, it is possible to suppress the width between the side edges 12b2 and 12a5 from becoming smaller, and it is easy to make the portion protrude forward from the low beam outer lens portion 12a.

[0050] In addition, the second upper fairing 31 also has a third protrusion 31c protruding forward along the lower edge 12b4 of the high beam outer lens portion 12b. The amount of the third protrusion 31c protruding forward is less than the amount of the first protrusion 31a protruding forward. As a result, it is possible to suppress the traveling wind that collides with the high beam outer lens portion 12b from turning upward, and to guide the wind toward the radiator 102 located below the headlamp unit 1. Moreover, the second protrusion 31b protrudes from the left and right side edges 12b2 and 12b3 of the high beam outer lens portion 12b, so it is also possible to suppress the traveling wind from turning to the left and right directions.

[0051] The lower surface of the first protrusion 31a, that is, the surface of the first protrusion 31a on the high beam outer lens portion 12b side, is inclined downward from the front end toward the rear. In addition, the left-right inner side surface of the second protrusion 31b, that is, the surface of the second protrusion 31b on the high beam outer lens portion 12b side, is inclined from the front end toward the rear toward the left-right inner side. As a result, the high beam passing through the high beam outer lens portion 12b is not easily blocked by the first protrusion 31a and the second protrusion 31b, and the high beam can be irradiated to a wide range.

[0052] The portion of the second upper fairing 31 along the lower edge 12a4 of the low beam outer lens portion 12a is inclined downward toward the front. In addition, the portion of the second upper fairing 31 along the first side edge 12a3 of the low beam outer lens portion 12a is inclined outward in the left-right direction toward the front. Moreover, the portion of the second upper fairing 31 along the second side edge 12a5 of the low beam outer lens portion 12a is inclined inward in the left-right direction toward the front. As a result, the low beam passing through the low beam outer lens portion 12a is not easily blocked by these portions, and the low beam can be irradiated to a wide range.

[0053] exist Figure 2 In the embodiment, the headlamp 2 includes a front housing 10 and a rear housing 11 mounted on the front housing 10 , and an outer lens 12 is mounted on the front housing 10 .

[0054] Figure 4 1 is an exploded front view of the headlamp 2 with the front housing 10 and the outer lens 12 removed. The headlamp 2 is provided with two low-beam reflectors 13 arranged at positions corresponding to the two low-beam outer lens portions 12a in front view, and one high-beam reflector 20 arranged at a position corresponding to the one high-beam outer lens portion 12b in front view.

[0055] The low beam reflector 13 has the same shape as the low beam outer lens portion 12 a , and its upper edge is inclined downward toward the left-right center C1 , and its side edge on the left-right center C1 side is inclined upward toward the left-right center C1 .

[0056] A low beam light source 14 for irradiating low beam light toward the low beam reflectors 13 is provided above each of the two low beam reflectors 13. The low beam light source 14 is provided with a low beam substrate for supplying power to the low beam light source 14 and a low beam radiator for cooling the low beam substrate.

[0057] When the low beam light source 14 radiates low beam light toward the low beam reflector 13, the low beam reflector 13 reflects the low beam light forward as low beam. The low beam reflected forward by the low beam reflector 13 passes through the low beam outer lens portion 12a and irradiates the front of the saddle-type vehicle 100.

[0058] Position lamps 18 are provided on the upper portions of the two low-beam reflectors 13 on the inner side in the left-right direction relative to the low-beam light source 14. Thus, the low-beam outer lens portion 12a can be made smaller than when the position lamps 18 are provided on the outer side in the left-right direction of the upper portions of the low-beam reflectors 13. The position lamps are lamps for notifying the presence of a saddle-type vehicle.

[0059] On the upper part of the high-beam reflector 20, high-beam light sources 21 are arranged side by side on the left and right sides to irradiate high-beam light toward the high-beam reflector 20. The high-beam light source 21 is provided with a high-beam substrate for supplying power to the high-beam light source 21 and a high-beam radiator for cooling the high-beam substrate. The low-beam light source 14 and the high-beam light source 21 of this embodiment are LEDs.

[0060] When the high-beam light source 21 radiates high-beam light toward the high-beam reflector 20, the high-beam reflector 20 reflects the high-beam light forward as high-beam. The high-beam reflected forward by the high-beam reflector 20 passes through the high-beam outer lens portion 12b and irradiates the front of the saddle-type vehicle 100.

[0061] In the front view, the high-beam light source 21 is arranged on the right side relative to the left end of the low-beam reflector 13 arranged on the left side, and is arranged on the left side relative to the right end of the low-beam reflector 13 arranged on the right side, and is arranged between the two low-beam reflectors 13 and the high-beam reflector 20 in the vertical direction. In addition, in the top view, the high-beam reflector 20 and the high-beam light source 21 overlap with the two low-beam reflectors 13 in the left-right direction.

[0062] The high beam reflector 20 has a high beam reflecting surface 20a and a non-reflecting surface 20b. The high beam reflecting surface 20a is opposed to the high beam light source 21 from below, and reflects the emitted light of the high beam light source 21 toward the front. The high beam reflecting surface 20a is curved toward the rear and downward. The non-reflecting surface 20b is provided on the surface of the high beam reflector 20 other than the high beam reflecting surface 20a. The non-reflecting surface 20b is located above the high beam reflecting surface 20a, and extends substantially flat in the front, rear, left, and right directions. The high beam reflector 20 also has a pair of side surfaces 20c extending in the up-down direction at the left and right ends of the high beam reflecting surface 20a and the non-reflecting surface 20b.

[0063] The high-beam reflective surface 20a is formed, for example, by vapor-depositing aluminum on the resin high-beam reflector 20. In addition, the non-reflective surface 20b is masked in the vapor-depositing process and aluminum is not vapor-deposited thereon. Therefore, the high-beam reflective surface 20a has the luster of aluminum, and the color of the resin material (for example, black) appears on the non-reflective surface 20b. Therefore, the reflectivity of the non-reflective surface 20b is lower than the reflectivity of the high-beam reflective surface 20a.

[0064] The low beam reflector 13 has a low beam reflecting surface 13a on its lower surface for reflecting low beam light forward. The low beam reflecting surface 13a is located below the low beam light source 14, is inclined downward toward the front, and is curved downward toward the rear. A reflective film is formed on the low beam reflecting surface 13a through a vapor deposition process similar to the high beam reflecting surface 20a.

[0065] Each light source 14, 21 and each reflector 13, 20 is supported by a light aiming bracket for adjusting the irradiation direction of each light. By adjusting the angle of the light aiming bracket relative to the housing 10, 11, the irradiation direction of the low beam and the high beam can be adjusted.

[0066] According to the headlamp unit 1 of the present embodiment and the saddle-ride type vehicle 100 including the headlamp unit 1, the following effects are achieved.

[0067] (1) The headlamp unit 1 includes:

[0068] Two low-beam outer lens portions 12a, which are arranged side by side and spaced apart from each other so as to allow the low-beam to pass forward; and

[0069] A high beam outer lens portion 12b is arranged on the right side relative to the left end of the low beam outer lens portion 12a arranged on the left side, and is arranged on the left side relative to the right end of the low beam outer lens portion 12a arranged on the right side, and is arranged at a distance below the two low beam outer lens portions 12a to allow the high beam to pass forward.

[0070] As a result, the size of each of the outer lens portions 12 a and 12 b can be reduced compared to a headlamp unit that emits high beam and low beam using one outer lens.

[0071] (2) The high-beam outer lens portion 12 b is disposed below the low-beam outer lens portion 12 a and is disposed rearward of the front end of the low-beam outer lens portion 12 a .

[0072] As a result, the high beam outer lens portion 12b can be made less noticeable, especially when the headlamp unit 1 is viewed from above or obliquely above. The high beam emits stronger light than the low beam, and is therefore more noticeable. By making the high beam outer lens portion 12b less noticeable as in the present embodiment, the headlamp unit 1 can be made to look smaller.

[0073] (3) The high-beam outer lens portion 12 b is inclined downward and rearward.

[0074] As a result, the area of ​​the high beam outer lens portion 12b when viewed from the front is smaller than the area of ​​the high beam outer lens portion 12b when viewed from a direction perpendicular to the front surface of the high beam outer lens portion 12b. Therefore, the high beam outer lens portion 12b can be made less conspicuous while ensuring the required amount of illumination for the high beam. In addition, since the front surface of the high beam outer lens portion 12b is tilted rearward, it is easy to guide the running wind passing through the front surface of the high beam outer lens portion 12b to the radiator 102 disposed at the rear of the headlamp unit 1. As a result, it is easy to guide the wind to the radiator 102 located at the rear and below the headlamp unit 1, thereby promoting the cooling of the engine by the radiator 102.

[0075] (4) The headlamp unit 1 further comprises:

[0076] a high-beam light source 21 for emitting high-beam light; and

[0077] The high-beam reflector 20 reflects the high-beam light emitted from the high-beam light source 21 toward the front, and is arranged at a position corresponding to the high-beam outer lens portion 12b in a front view.

[0078] The high beam reflector 20 has:

[0079] A high-beam reflecting surface 20a that reflects the light for the high beam toward the front; and

[0080] The reflectivity of the non-reflective surface 20b is lower than the reflectivity of the high-beam reflecting surface 20a.

[0081] As a result, when the high beam is not on, when light from a street lamp or the like illuminates the headlamp unit 1, or when light for low beam is irradiated to the high beam reflector in the headlamp unit, since the high beam reflector 20 has a non-reflective surface 20b, the light or the low beam light is not easily reflected by the high beam reflector 20, thereby making the high beam outer lens portion 12b less conspicuous.

[0082] (5) The high-beam outer lens portion 12b is arranged below the low-beam outer lens portion 12a.

[0083] The high-beam light source 21 is disposed above the high-beam reflector 20 .

[0084] As a result, the high beam light source can be prevented from protruding below the high beam reflector, and the high beam reflector can be arranged as much as possible below the headlamp unit. Thus, the height of the high beam reflector and the high beam outer lens portion is lowered, and the high beam outer lens portion can be made less conspicuous.

[0085] (6) The high-beam outer lens portion 12b is arranged rearward relative to the front end of the low-beam outer lens portion 12a.

[0086] The high-beam reflecting surface 20a is opposed to the high-beam light source 21 from below.

[0087] The non-reflecting surface 20 b is formed at least above the high-beam reflecting surface 20 a among the surfaces other than the high-beam reflecting surface 20 a .

[0088] As a result, when external light such as road surface reflected light from below the headlamp unit 1 strikes the high-beam reflector 20, the non-reflective surface 20b suppresses reflection of the external light. This makes the high-beam outer lens portion 12b less conspicuous.

[0089] (7) The headlamp unit 1 further comprises:

[0090] A high-beam light source 21 , which radiates high-beam light;

[0091] A high-beam reflector 20 that reflects the high-beam light emitted from the high-beam light source 21 toward the front and is disposed at a position corresponding to the high-beam outer lens portion 12b when viewed from the front;

[0092] two low-beam light sources 14 for emitting low-beam light; and

[0093] Two low-beam reflectors 13 are provided to reflect the low-beam light emitted from the two low-beam light sources 14 toward the front, and are arranged at positions corresponding to the two low-beam outer lens portions 12a in a front view.

[0094] The high-beam light source 21 is disposed on the right side of the left end of the low-beam reflector 13 disposed on the left side and on the left side of the right end of the low-beam reflector 13 disposed on the right side, and is disposed between the two low-beam reflectors 13 and the high-beam reflector 20 in the vertical direction.

[0095] As a result, the high-beam light source 21 is suppressed from protruding in the vertical direction relative to the low-beam reflector 13 and the high-beam reflector 20 , and the headlamp unit 1 can be easily downsized.

[0096] (8) The headlamp unit 1 further comprises:

[0097] An outer lens 12 having a high-beam outer lens portion 12 b and two low-beam outer lens portions 12 a ;

[0098] a headlamp 2 to which an outer lens 12 is mounted; and

[0099] An upper fairing 3, which covers the headlight 2,

[0100] The high beam outer lens portion 12b is arranged below the low beam outer lens portion 12a.

[0101] The upper cowl 3 covers the high-beam outer lens portion 12 b in a plan view.

[0102] As a result, the upper portion of the high-beam outer lens portion 12 b is covered by the upper cowl 3 , so that the high-beam outer lens portion 12 b can be made less noticeable particularly when the headlamp unit 1 is viewed from above or obliquely above.

[0103] (9) The headlamp unit 1 further comprises:

[0104] An outer lens 12 having a high-beam outer lens portion 12 b and two low-beam outer lens portions 12 a ;

[0105] a headlamp 2 to which an outer lens 12 is mounted; and

[0106] An upper fairing 3, which covers the headlight 2,

[0107] The upper cowl 3 covers the high-beam outer lens portion 12 b in a side view.

[0108] As a result, the side of the high-beam outer lens portion 12 b is covered by the upper cowl 3 , so that the high-beam outer lens portion 12 b can be made less noticeable particularly when the headlamp unit 1 is viewed from the side.

[0109] (10) The saddle-ride type vehicle 100 includes a headlight unit 1,

[0110] The headlamp unit 1 comprises:

[0111] Two low-beam outer lens portions 12a, which are arranged side by side and spaced apart from each other so as to allow the low-beam to pass forward; and

[0112] A high beam outer lens portion 12b is arranged on the right side relative to the left end of the low beam outer lens portion 12a arranged on the left side, and is arranged on the left side relative to the right end of the low beam outer lens portion 12a arranged on the right side, and is arranged at a distance below the two low beam outer lens portions 12a to allow the high beam to pass forward.

[0113] As a result, the headlamp unit 1 has a compact outer lens 12 , and the appearance of the saddle-ride type vehicle 100 including such a headlamp unit 1 is improved.

[0114] In addition, the headlamp unit and the saddle-ride type vehicle including the headlamp unit of the present disclosure are not limited to the configurations of the above-described embodiments, and various modifications are possible.

[0115] In this specification, a two-wheeled motorcycle is disclosed as a riding type vehicle, but the present invention can also be applied to other riding type vehicles. For example, the riding type vehicle can also be a three-wheeled vehicle or a four-wheeled beach vehicle.

[0116] The saddle-type vehicle may use an electric motor as a driving source in addition to the engine, or the saddle-type vehicle may be a hybrid vehicle using both the electric motor and the engine as driving sources.

[0117] As in the present embodiment, the headlight unit is preferably supported by a bracket that is angularly displaced together with the front fork. The headlight unit disclosed in the present invention is suitable for use in naked vehicles whose engines are partially exposed. In addition, the headlight unit is not limited thereto. For example, the headlight unit may be fixed to the vehicle frame regardless of the angular displacement of the front fork.

[0118] The high beam is appropriately lit by the driver's operation, but is not limited to this. For example, a riding-type vehicle may also be equipped with a sensor for detecting the surrounding conditions, specifically, detecting the presence or absence of an oncoming vehicle or a vehicle in front. In this case, if the sensor output determines that there is an oncoming vehicle or a vehicle in front, the high beam is turned off, and if the sensor output determines that no oncoming vehicle or vehicle in front is identified, the high beam is turned on.

[0119] The headlamp unit 1 of the present embodiment includes an upper fairing, but may not include an upper fairing. In addition, the upper fairing 3 of the present embodiment is divided into upper and lower parts, but is not limited thereto, and may be an integral structure or other divided structures such as a left-right divided structure.

[0120] The high-beam outer lens portion 12b is disposed below the two low-beam outer lens portions 12a at a distance therefrom, but may also be disposed above the two low-beam outer lens portions 12a at a distance therefrom. In this case, each outer lens portion can also be miniaturized.

[0121] In the front view, the area of ​​the high beam outer lens portion 12b is smaller than the area of ​​the low beam outer lens portion 12a, thereby making the high beam outer lens portion 12b less conspicuous, but in the front view, the area of ​​the high beam outer lens portion 12b may also be smaller than the total area of ​​the two low beam outer lens portions 12a. In this case, the high beam outer lens portion can also be made less conspicuous.

[0122] Aluminum is vapor-deposited on the side surface 20c of the high-beam reflector 20, but aluminum may not be vapor-deposited, that is, the side surface 20c of the high-beam reflector 20 may be a non-reflective surface. When the side surface 20c of the high-beam reflector 20 is a non-reflective surface, when the high beam is not on, light from street lamps and the like is less likely to be reflected by the high-beam reflector, and the high-beam outer lens portion can be made less conspicuous.

[0123] Two high-beam light sources 21 are provided on the upper portion of the high-beam reflector 20 . However, if light required for high beam can be provided by one light source, one high-beam light source may be provided on the upper portion of the high-beam reflector 20 .

[0124] The high-beam light source 21 is provided on the upper portion of the high-beam reflector 20 , but may be provided on the lower portion of the high-beam reflector.
