[0013] The vehicle visualizing device of an eighth aspect of the present invention is the vehicle visualizing device of any one of the first to seventh aspects of the present invention, wherein a curvature in the extension direction of the first guide member and a curvature in the extension direction of the second guide member are different.

[0014] A ninth aspect of the present invention is a vehicle visualization device according to any one of the first to eighth aspects of the present invention, comprising a covering portion arranged at a position in the vertical direction of the first guide member and the second guide member and covering the periphery of the visualization mechanism, and a displacement mechanism arranged at a position in the vertical direction of the first guide member and the second guide member and displaces the visualization mechanism. Effect of the Invention

[0015] In the vehicle visualizing device according to the first aspect of the present invention, the visualizing mechanism assists the visualizing of the vehicle occupant. The first guide member and the second guide member extend in the vehicle width direction and have their tip sides extending outward in the vehicle width direction from the visualizing mechanism. The first guide member and the second guide member guide the light emitted by the first emission portion and the second emission portion, respectively, and irradiate the light from the tip side.

[0016] Here, the first guide member and the second guide member are arranged vertically side by side, which makes it possible to reduce the arrangement dimensions of the first guide member and the second guide member in the front-rear direction of the vehicle.

[0017] Furthermore, the first and second emission portions are disposed on the inner side in the vehicle width direction of the first and second guide members, respectively, so that the wiring distance from the inner side in the vehicle width direction to the first and second emission portions can be shortened.

[0018] As a result, the vehicle visual recognition device can be made more compact.

[0019] In the vehicle visualizing device of the second aspect of the present invention, the first guide member and the second guide member extend along the light emission directions of the first emission portion and the second emission portion, respectively, so that the first guide member and the second guide member can effectively guide the light emitted by the first emission portion and the second emission portion, respectively.

[0020] In a vehicle visualizing device of a third aspect of the present invention, a plurality of reflective portions are provided at intervals on one of the first guide member and the second guide member, and the reflective portions reflect light guided by one of the first guide member and the second guide member.

[0021] Here, the reflecting portion does not face the other of the first guide member and the second guide member, which makes it possible to prevent light leaking between the reflecting portions of one of the first guide member and the second guide member from being incident on the other of the first guide member and the second guide member.

[0022] In the vehicle visual confirmation device of the fourth aspect of the present invention, the first guide member and the second guide member are housed in a housing, and a light blocking portion of the housing blocks light between the first guide member and the second guide member, thereby making it possible to prevent light from being incident between the first guide member and the second guide member.

[0023] In the vehicle visual confirmation device of the fifth aspect of the present invention, one of the first guide member and the second guide member irradiates light toward the occupant, so that the occupant can visually confirm the light.

[0024] In the vehicle visual confirmation device of the sixth aspect of the present invention, one of the first guide member and the second guide member is disposed below the other of the first guide member and the second guide member, thereby improving the visibility of the light irradiated by one of the first guide member and the second guide member.

[0025] In the vehicle visual confirmation device of the seventh aspect of the present invention, the position of the light emitted from the tip end of the first guide member and the position of the light emitted from the tip end of the second guide member overlap in the vertical direction, so that the position of the light emitted from the tip end of the first guide member and the position of the light emitted from the tip end of the second guide member can be easily arranged.

[0026] In the vehicle visual confirmation device of the eighth aspect of the present invention, the first guide member and the second guide member have different curvatures in their extending directions, which increases the degree of freedom in arranging the first guide member and the second guide member.

[0027] In the vehicle visualizing device of the ninth aspect of the present invention, the covering portion covers the periphery of the visualizing mechanism, and the displacement mechanism displaces the visualizing mechanism.

[0028] Here, the covering portion and the displacement mechanism are disposed at positions in the up-down direction of the first guide member and the second guide member. Therefore, even if the covering portion and the displacement mechanism are present, the arrangement dimensions of the first guide member and the second guide member in the vehicle front-rear direction can be reduced as described above, thereby preventing the vehicle visualizing device from becoming large in size in the vehicle front-rear direction.

[0052] Next, the operation of this embodiment will be described.

[0053] In the door mirror device 10 having the above configuration, in the lamp device 22, the first LED 44 of the circuit board 42 emits light to the vehicle width direction inner end surface of the first light guide 48, so that the first light guide 48 guides the light incident on the vehicle width direction inner end surface and irradiates it from the vehicle width direction outer end surface. Furthermore, the light irradiated from the vehicle width direction outer end surface of the first light guide 48 is transmitted through the vehicle width direction outer end wall of the exposed portion 38C of the first lens 38, and is radiated in a direction toward the vehicle width direction outer side as it moves toward the rear of the vehicle through the vehicle width direction outer end surface of the exposed hole 14 of the visor 12. The color of the light radiated from the first lens 38 is amber, and the first LED 44, the first light guide 48, and the first lens 38 function as a turn lamp of the vehicle to notify the outside of the vehicle of the traveling direction of the vehicle.

[0054] In addition, the second LED 46 of the circuit board 42 emits light to the inner end surface of the second light guide 50 in the vehicle width direction, so that the second light guide 50 guides the light incident on the inner end surface in the vehicle width direction and irradiates it from the outer end surface in the vehicle width direction. Furthermore, the light irradiated from the outer end surface in the vehicle width direction of the second light guide 50 is transmitted through the vehicle rear wall of the second lens 40 and is radiated in a direction toward the inside of the vehicle width direction (toward the occupant) as it moves toward the rear of the vehicle through the open hole 16 of the visor 12. The color of the light radiated from the second lens 40 is amber (different in brightness and intensity from the light radiated from the first lens 38), and the second LED 46, the second light guide 50, and the second lens 40 function as a BSM (Blind Spot Monitor) of the vehicle to notify the occupant of the approach of another vehicle to the rear of the vehicle and to the outside in the vehicle width direction.

[0055] Here, the extending portion of the first light guide 48 in the vehicle width direction and the extending portion of the second light guide 50 in the vehicle width direction are aligned in the up-down direction. Therefore, the arrangement dimensions in the vehicle front-rear direction of the extending portion of the first light guide 48 in the vehicle width direction and the extending portion of the second light guide 50 in the vehicle width direction can be reduced.

[0056] Furthermore, the first LED 44 and the second LED 46 of the circuit board 42 are disposed on the inner side in the vehicle width direction of the first light guide 48 and the second light guide 50, respectively. Therefore, the wiring distance from the inner side in the vehicle width direction (vehicle body side) to the first LED 44 and the second LED 46 can be shortened, and the wiring arrangement space in the vehicle width direction can be reduced.

[0057] As a result, the door mirror device 10 can be made smaller in size in the vehicle front-rear direction and in the vehicle width direction.

[0058] Moreover, the vicinity of the outer end portion in the vehicle width direction of the first light guide 48 and the vicinity of the outer end portion in the vehicle width direction of the second light guide 50 are aligned in the up-down direction. Therefore, the arrangement dimensions in the vehicle width direction of the vicinity of the outer end portion in the vehicle width direction of the first light guide 48 and the vicinity of the outer end portion in the vehicle width direction of the second light guide 50 can be reduced, and the door mirror device 10 can be made even smaller in size in the vehicle width direction.

[0059] Furthermore, the cover plate 12A and the adjustment device 18 of the visor 12 are disposed at positions in the up-down direction of the lamp device 22 (including the first light guide 48 and the second light guide 50). Therefore, even if the cover plate 12A and the adjustment device 18 are present on the vehicle rear side of the first light guide 48 and the second light guide 50, the arrangement dimensions of the first light guide 48 and the second light guide 50 in the vehicle front-rear direction can be reduced as described above, thereby preventing the door mirror device 10 from becoming large in the vehicle front-rear direction.

[0060] Further, the inner end portion in the vehicle width direction of the first light guide 48 and the inner end portion in the vehicle width direction of the second light guide 50 extend along the light emission directions of the first LED 44 and the second LED 46, respectively. Therefore, the first light guide 48 and the second light guide 50 can properly guide the light emitted by the first LED 44 and the second LED 46, respectively.

[0061] Furthermore, the light blocking plate 26, the light blocking rib 30 and the lower restricting claw 28 of the housing 24 block light between the first light guide 48 and the second light guide 50. This makes it possible to prevent light from being incident between the first light guide 48 and the second light guide 50, and to prevent the light guided by the first light guide 48 and the light guided by the second light guide 50 from mixing.

[0062] Moreover, the first light guide 48 is disposed below the second light guide 50. Therefore, while the lower portion of the mirror 20 reflecting the road surface becomes darker than the upper portion of the mirror 20 reflecting the sky, the first lens 38 can be brought closer to the lower portion of the mirror 20, and the contrast between the light irradiated by the first light guide 48 and emitted by the first lens 38 and the lower portion of the mirror 20 can be increased, thereby improving the visibility of the light.

[0063] Further, a plurality of reflective surfaces 48C are provided at intervals on the first light guide 48, and the reflective surfaces 48C reflect the light guided by the first light guide 48. Therefore, it is possible to prevent the light guided by the first light guide 48 from leaking from the first light guide 48.

[0064] Furthermore, the reflective surface 48C is provided on the back surface of the first light guide 48 and does not face the second light guide 50. This makes it possible to prevent light leaking between the reflective surfaces 48C of the first light guide 48 from entering the second light guide 50 and mixing with the light guided by the second light guide 50.

[0065] Also, the vicinity of the outer end in the vehicle width direction of the second light guide 50 has a larger curvature toward the inside in the vehicle width direction compared to the vicinity of the outer end in the vehicle width direction of the first light guide 48. Therefore, the outer end in the vehicle width direction of the second light guide 50 can be disposed inward in the vehicle width direction from the outer end in the vehicle width direction of the first light guide 48, and it is not necessary to align the outer end in the vehicle width direction of the first light guide 48 and the outer end in the vehicle width direction of the second light guide 50 in the vertical direction, thereby increasing the degree of freedom in disposing the outer end in the vehicle width direction of the first light guide 48 and the outer end in the vehicle width direction of the second light guide 50.

[0066] Furthermore, the position where light is emitted from the outer end of the first light guide 48 in the vehicle width direction (the outer end wall of the exposed portion 38C of the first lens 38 in the vehicle width direction) and the position where light is emitted from the outer end of the second light guide 50 in the vehicle width direction (the rear side wall of the second lens 40) are overlapped in the vertical direction. This makes it possible to reduce the vertical arrangement dimensions of the exposed portion 38C of the first lens 38 and the second lens 40, and makes it easy to arrange the exposed portion 38C of the first lens 38 and the second lens 40.

[0067] Furthermore, the first LED 44 and the second LED 46 are provided on the outer surface (the same surface) in the vehicle width direction of the circuit board 42. Therefore, unlike a case in which the first LED 44 and the second LED 46 are provided on the outer surface and the inner surface in the vehicle width direction of the circuit board 42, respectively, the configuration of the circuit board 42 can be simplified, and costs can be reduced.

[0068] In this embodiment, the light emitted from the first lens 38 and the light emitted from the second lens 40 are the same color (amber). However, the light emitted from the first lens 38 and the light emitted from the second lens 40 may be different colors.

[0069] In the present embodiment, the second LED 46, the second light guide 50, and the second lens 40 function as a BSM. However, the second LED 46, the second light guide 50, and the second lens 40 may have a function other than the BSM to notify the occupants of the vehicle.

[0070] Furthermore, in this embodiment, the first light guide 48 is disposed below the second light guide 50. However, the second light guide 50 may be disposed below the first light guide 48. In this case, the lower part of the mirror 20 reflecting the road surface is darker than the upper part of the mirror 20 reflecting the sky, but the second lens 40 can be brought closer to the lower part of the mirror 20, and the difference in brightness between the light irradiated by the second light guide 50 and emitted by the second lens 40 and the lower part of the mirror 20 can be increased, thereby improving the visibility of the light.

[0071] In this embodiment, the first light guide 48 is provided with the reflective surface 48C. However, the second light guide 50 may be provided with the reflective surface 48C.

[0072] Furthermore, in this embodiment, the vehicle width direction outer end (tip) of the first light guide 48 and the vehicle width direction outer end (tip) of the second light guide 50 may overlap in position in the up-down direction.

[0073] In this embodiment, the viewing mechanism is the mirror 20. However, the viewing mechanism may be a camera, and the passenger's viewing may be assisted by an image captured by the camera. [Explanation of symbols]
