[0005] Patent Document 1: Japanese Patent Application Publication No. 2021-91303 Summary of the invention

[0006] [Problems to be solved by the invention]

[0007] The present inventors have studied the following structure in a vehicle lamp with a detection device having a detection device such as a laser used in driving assistance technology. The vehicle lamp with a detection device includes a lamp unit and a detection unit. The detection unit detects an object on a predetermined detection direction side.

[0008] The lamp unit includes a light source and a lens. The lens covers the light source from the detection direction side. A receiving recess is formed on the lens, and the receiving recess is recessed in the reverse detection direction opposite to the detection direction. The detection unit includes a detection device, a bracket and a cover. At least a part of the detection device is received in the receiving recess. The detection device has a detection surface for detecting an object at an end portion on the detection direction side. The bracket supports the detection device from the reverse detection direction side.

[0009] The cover covers the detection device from the detection direction side. The cover is provided with a flange protruding toward the opposite detection direction side. The flange is engaged with the bracket at a predetermined engagement position, thereby mounting the cover on the bracket.

[0010] The inventors of the present invention have noticed that the following problem may occur in such a vehicle lamp with a detection device: when snow or water penetrates into the inner side of the accommodating recess from the gap between the upper end of the cover and the inner peripheral surface of the accommodating recess, the snow or water may enter between the detection surface and the inner side of the cover, thus adversely affecting the detection performance of the detection device.

[0011] The present invention is made in view of the above situation, and an object of the present invention is to prevent snow or water from entering between the detection surface and the inner surface of the cover.

[0012] [Technical means to solve the problem]

[0013] The inventors found that the above-mentioned object can be achieved by providing a flange on the cover, the flange being located above the detection device and protruding to the side opposite to the detection direction from the detection surface, thereby completing the present invention. The present invention is a vehicle lamp with a detection device having the following structures (1) to (5).

[0014] (1) A vehicle lamp with a detection device, comprising a lamp unit mounted on a vehicle and a detection unit for detecting an object in a predetermined detection direction, wherein:

[0015] The lamp unit comprises a light source and a lens covering the light source from the detection direction side, wherein a receiving recess is formed on the lens and is recessed in a reverse detection direction opposite to the detection direction.

[0016] The detection unit comprises a detection device at least partly accommodated in the accommodation recess, a bracket supporting the detection device from the side opposite to the detection direction, and a cover covering the detection device from the side opposite to the detection direction.

[0017] The cover is provided with a flange protruding in the reverse detection direction.

[0018] The flange is engaged with the bracket at a predetermined engagement position, thereby mounting the cover on the bracket.

[0019] The detection device has a detection surface for performing the detection at the end of the detection direction.

[0020] The flange is located above the detection device and protrudes to the side in the opposite direction of the detection direction than the detection surface.

[0021] According to this structure, the flange protrudes above the detection device and in the direction opposite to the detection surface. Therefore, even if snow or water infiltrates into the inner side of the accommodating recess from the gap between the upper end of the cover and the inner peripheral surface of the accommodating recess, the flange can prevent the snow or water from entering between the detection surface and the inner side of the cover.

[0022] (2) The vehicle lamp with a detection device according to (1), wherein the flange is located above the detection device and protrudes to the side opposite to the detection direction than an end surface of the detection device on the side opposite to the detection direction.

[0023] According to this structure, even if snow or water falls downward from the end of the flange on the opposite detection direction side, the snow or water will fall to the opposite detection direction side of the detection device. Therefore, it is possible to more firmly prevent snow or water from entering between the detection surface and the inner side of the cover.

[0024] (3) The vehicle lamp with a detection device according to (1) or (2), wherein the engagement portion is located on the side opposite to the detection direction than the detection surface.

[0025] According to this structure, since the engaging portion is located on the side opposite to the irradiation direction than the detection surface, even if snow or water falls from the engaging portion to the bottom thereof, the snow or water will fall on the side opposite to the detection direction than the detection surface, thereby more firmly preventing snow or water from entering between the detection surface and the inner side of the cover.

[0026] (4) The vehicle lamp with a detection device according to (1) or (2), wherein the bracket is provided with an engagement protrusion protruding in the detection direction, and the flange is engaged with the engagement protrusion at the engagement portion.

[0027] The bracket is provided with a receiving portion, the receiving portion protruding to a range including a portion directly below at least a portion of the engaging protrusion.

[0028] Compared with the two ends of the width direction of the aforementioned engaging protrusion, the two ends of the aforementioned width direction of the aforementioned receiving portion are located on the outer side of the aforementioned width direction.

[0029] The upper surface of the receiving portion is inclined toward a downward side as it moves toward the reverse detection direction.

[0030] According to this structure, when snow or water falls downward from the widthwise end of the projection, the receiving portion can block the snow or water and guide it in the reverse detection direction. Therefore, it is possible to more firmly prevent snow or water from entering between the detection surface and the inner side of the cover.

[0031] (5) The vehicle lamp with a detection device according to (1) or (2), wherein the bracket is provided with a surrounding portion.

[0032] The surrounding portion has an inner protrusion and an outer protrusion arranged in a direction perpendicular to the detection direction and protruding in the detection direction.

[0033] The flange is disposed between the inner protrusion and the outer protrusion.

[0034] According to this structure, since there is a surrounding portion in addition to the engaging portion, the cover can be mounted on the bracket more stably.

[0035] (Effects of the Invention)

[0036] As described above, according to the structure of (1), it is possible to prevent snow or water from entering between the detection surface and the back surface of the cover. Furthermore, according to the structures of (2) to (5) cited from (1), respective additional effects can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments at all, and can be implemented with appropriate changes within the scope of the present invention.

[0052] [First embodiment]

[0053] Figure 1 The vehicle lamp 100 with a detection device shown is a headlamp on the left side of the vehicle and is mounted on the vehicle. The vehicle lamp 100 with a detection device includes a lamp unit 102 and a detection unit 106. The lamp unit 102 includes a housing 10, a light source 20, and a lens 30. The detection unit 106 includes a detection device 60, a bracket 50, and a cover 70. In this embodiment, the detection device 60 is a laser device that detects an object by irradiating an electric wave and detecting its reflected wave.

[0054] The following, such as Figure 3 As shown, the direction in which the detection device 60 irradiates the radio waves, that is, the direction in which the object is detected, is called the "Y-direction", and the opposite direction is called the "Y+ direction". In addition, the "Y-direction" can also be replaced by the "detection direction", and the "Y+ direction" can also be replaced by the "reverse detection direction". Hereinafter, the "Y-direction" and the "Y+ direction" are collectively referred to as the "Y direction". The Y direction is a direction inclined relative to the vehicle length direction CL in the horizontal plane. Hereinafter, the direction orthogonal to the Y direction in the horizontal plane is referred to as the "X direction". In addition, the direction on the inner side of the vehicle width direction CW in the X direction is referred to as the "X-direction", and the opposite direction is referred to as the "X+ direction".

[0055] Figure 1 The housing 10 shown is a box-shaped housing that is open toward the Y-direction. The light source 20 is disposed inside the housing 10 and radiates light toward the Y-direction side. The lens 30 is mounted on the housing 10 and covers the light source 20 from the Y-direction side. Figure 4 As shown in FIG. 1 , a housing recess 36 that is recessed toward the Y+ direction side is formed on the lens 30. The housing recess 36 opens toward the Y- direction and downward.

[0056] like Figure 4 As shown, the bracket 50 is disposed inside the receiving recess 36. Figure 6 As shown in FIG. 1 , the bracket 50 includes a bracket body 52 and a mounting portion 51. The bracket 52 is in the shape of a plate extending in the vertical direction and the X direction. The mounting portion 51 protrudes downward from the lower end of the bracket body 52. Figure 1 As shown, the lower end of the mounting portion 51 is fixed to the vehicle body or the housing 10 below the lens 30 . Thus, the bracket body 52 is disposed inside the housing recess 36 .

[0057] like Figure 6 As shown, on the surface of the bracket body 52 on the Y-direction side, as shown in FIG. Figure 2 As shown in FIG. 5 , the detection device 60 is mounted by screws or the like. That is, the bracket 50 supports the detection device 60 from the Y+ direction side. Figure 3 As shown, the detection device 60 is accommodated in the accommodating recess 36. In addition, in the present embodiment, the detection device 60 is entirely accommodated in the accommodating recess 36. However, instead, only a portion of the detection device 60 may be accommodated in the accommodating recess 36. Specifically, for example, the end portion of the detection device 60 on the Y-direction side may protrude from the opening of the accommodating recess 36 in the Y-direction, and the central portion of the cover 70 may protrude from the opening of the accommodating recess 36 in the Y-direction.

[0058] like Figure 6 As shown, the detection device 60 has a detection surface 60s for detection at the end on the Y-direction side. Specifically, the detection device 60 irradiates radio waves from the detection surface 60s toward the Y-direction side and detects the reflected waves using the detection surface 60s, thereby performing detection on the Y-direction side.

[0059] The bracket body 52 is provided with a plurality of surrounding portions 57 , a plurality of engaging protrusions 53 , and a plurality of receiving portions 54 .

[0060] like Figure 6 As shown in FIG. 1 , the surrounding portions 57 are provided at the upper edge, the lower edge, and the edge on the X+ direction side of the bracket body 52. ​​Each surrounding portion 57 protrudes in the Y-direction. Hereinafter, the surrounding portion 57 at the upper edge of the bracket body 52 is referred to as the "upper side surrounding portion 57", the surrounding portion 57 at the lower edge is referred to as the "lower side surrounding portion 57", and the surrounding portion 57 at the edge on the X+ direction side is referred to as the "X+ side surrounding portion 57".

[0061] Each surrounding portion 57 has an inner protrusion 57a ​​and an outer protrusion 57b. The inner protrusion 57a ​​and the outer protrusion 57b in the upper and lower surrounding portions 57 are arranged in the vertical direction and protrude in the Y-direction. The inner protrusion 57a ​​and the outer protrusion 57b in the surrounding portion 57 on the X+ side are arranged in the X direction and protrude in the Y-direction. That is, the inner protrusion 57a ​​and the outer protrusion 57b are arranged in a direction orthogonal to the Y direction and protrude in the Y-direction respectively. Fig.13 As shown, the front end portion of the outer protrusion 57 b in the upper surrounding portion 57 protrudes upward and engages with the inner peripheral portion of the accommodating recess 36 .

[0062] like Figure 6As shown, the engaging protrusions 53 are provided on the upper edge, the lower edge, the edge on the X-direction side, and the edge on the X+ direction side of the bracket body 52. ​​Each engaging protrusion 53 protrudes in the Y-direction. Hereinafter, the engaging protrusion 53 at the upper edge of the bracket body 52 is referred to as "the engaging protrusion 53 on the upper side", and the engaging protrusion 53 at the lower edge is referred to as "the engaging protrusion 53 on the lower side". In addition, the engaging protrusion 53 at the edge on the X-direction side of the bracket body 52 is referred to as "the engaging protrusion 53 on the X-side", and the engaging protrusion 53 at the edge on the X+ direction side is referred to as "the engaging protrusion 53 on the X+ side". The width direction of the engaging protrusions 53 on the upper and lower sides is the X direction, and the width direction of the engaging protrusions 53 on the X-side and X+ side is the up-down direction.

[0063] A hook 53f is provided at the end of each engaging protrusion 53 on the Y-direction side. Among the engaging protrusions 53, there are engaging protrusions whose hook 53f protrudes inward, that is, on the detection device 60 side, and engaging protrusions whose hook 53f protrudes outward, that is, on the opposite side of the detection device 60 side. Specifically, in the present embodiment, the hook 53f of the upper engaging protrusion 53 protrudes outward, that is, upward. In addition, the hook 53f of the lower engaging protrusion 53 protrudes inward, that is, upward. In addition, the hook 53f of the engaging protrusion 53 on the X-side protrudes inward, that is, in the X+ direction. In addition, the hook 53f of the engaging protrusion 53 on the X+ side protrudes outward, that is, in the X+ direction.

[0064] like Figure 6 As shown, the receiving portion 54 exists for each upper engaging protrusion 53. Figure 7 As shown, the receiving portion 54 is in a U-shaped shape when viewed along the Y direction. The receiving portion 54 protrudes from the bracket body 52 to a range directly below the portion of the engaging protrusion 53 at least near the root. The width of the receiving portion 54 in the X direction is greater than the width of the engaging protrusion 53 in the X direction. Therefore, compared with the two ends of the engaging protrusion 53 in the X direction, the two ends of the receiving portion 54 in the X direction are located outside the X direction. More specifically, compared with the two ends of the engaging protrusion 53 in the X direction, the inner side surfaces 54i, 54j on both sides of the receiving portion 54 in the X direction are located outside the X direction. The upper surface 54s of the bottom of the receiving portion 54 is gradually inclined toward the downward side as it advances in the Y+ direction. A drainage hole 52h is provided in the portion of the bracket body 52 located inside the root of the receiving portion 54.

[0065] like Figure 5As shown in FIG. 1 , the cover 70 includes a cover body 77 and a flange 75. The cover body 77 is in the shape of a plate extending in the up-down direction and the X direction. The flange 75 extends from a portion of the cover body 77 slightly inside the edge and toward the Y+ direction. Engagement holes 75h are provided at a plurality of locations on the flange 75. Specifically, the engagement holes 75h are provided at locations corresponding to the hooks 53f.

[0066] like Fig.13 As shown, by inserting the flange 75 between the inner protrusion 57a ​​and the outer protrusion 57b in the surrounding portion 57, and as shown in FIG. Figure 5 As shown in FIG. 1 , the inner circumference of the engagement hole 75h engages with each hook 53f, and the cover 70 is mounted on the bracket 50. Hereinafter, the portion where the inner circumference of the engagement hole 75h engages with the hook 53f is referred to as the "engagement portion Ep". Figure 3 As shown, the cover body 77 covers the detection device 60 from the Y-direction side. The cover 70 is made of resin or the like, and is configured to be able to transmit radio waves.

[0067] like Fig.14 As shown in FIG. 1 , the flange 75 protrudes to the Y+ direction side more than the detection surface 60s. More specifically, the flange 75 protrudes to the Y+ direction side more than the end surface 60t on the Y+ direction side of the detection device 60. Figure 8 As shown, the engagement portion Ep is located on the Y+ direction side relative to the detection surface 60s.

[0068] like Figure 8 , Fig. 9 As shown in FIG. 1 , a gap G is formed between the edge of the cover body 77 and the inner peripheral surface of the accommodating recess 36. Specifically, as shown in FIG. Figure 8 As shown in FIG. 1 , an upper gap G is formed between the upper end of the cover body 77 and the inner peripheral surface of the accommodating recess 36. Fig. 9 As shown, a gap G on the X-side is formed between the end of the cover body 77 in the X-direction and the inner peripheral surface of the accommodating recess 36. In addition, a gap on the X+ side (not shown) is formed between the end of the cover body 77 in the X+ direction and the inner peripheral surface of the accommodating recess 36.

[0069] The following, such as Figure 8As shown, the imaginary straight line from the portion of the gap G adjacent to the engagement portion Ep toward the engagement portion Ep is called the "insertion imaginary line vL". A lens side guide surface 36s extending along the insertion imaginary line vL is provided on the portion of the inner circumferential surface of the accommodating recess 36 adjacent to the insertion imaginary line vL, that is, the portion facing the gap G. A cover side guide surface 77s extending along the insertion imaginary line vL is provided on the portion of the cover body 77 adjacent to the insertion imaginary line vL. Specifically, the lens side guide surface 36s and the cover side guide surface 77s are both parallel to the insertion imaginary line vL. In addition, the lens side guide surface 36s and the cover side guide surface 77s are parallel to each other.

[0070] Next, the cover removal method of this embodiment is described. First, prepare the cover shown above. Figure 1 The vehicle lamp 100 with a detection device shown in FIG. Fig.10 , Fig.11 As shown, a rod-shaped jig J is inserted toward the engagement portion Ep along the lens-side guide surface 36s and the cover-side guide surface 77s, that is, the insertion imaginary line vL, from the gap G. Thus, the front end of the jig J releases the inner circumference of the engagement hole 75h at the engagement portion Ep from the hook 53f.

[0071] Specifically, if Fig.10 As shown in the figure, for the upper engaging protrusion 53, the hook 53f is pressed in by the front end of the jig J, thereby releasing the engagement of the inner peripheral surface of the engaging hole 75h with respect to the hook 53f. Similarly, for the engaging protrusion 53 on the X+ side, the engagement is also released. That is, for the hook 53f protruding outward, the hook 53f is pressed in by the front end of the jig J, thereby releasing the engagement of the inner peripheral surface of the engaging hole 75h with respect to the hook 53f.

[0072] On the other hand, Fig.11 As shown, for the engagement protrusion 53 on the X-side, the front end of the jig J is pressed between the hook 53f and the inner circumference of the engagement hole 75h. Thus, the hook 53f is pushed out to the X-direction side by the front end of the jig J, and the engagement of the inner circumference of the engagement hole 75h with respect to the hook 53f is released. Similarly, for the engagement protrusion 53 on the lower side, the engagement is also released. That is, for the hook 53f protruding inward, the front end of the jig J is pressed between the hook 53f and the inner circumference of the engagement hole 75h, thereby releasing the engagement of the inner circumference of the engagement hole 75h with respect to the hook 53f.

[0073] Hereinafter, the configuration and effects of the present embodiment will be summarized.

[0074] like Fig.14As shown, the flange 75 protrudes to the Y+ direction side of the detection surface 60s at a position higher than the detection device 60. Therefore, even if snow or water infiltrates into the inner side of the accommodating recess 36 from the gap G between the upper end of the cover 70 and the inner peripheral surface of the accommodating recess 36, the flange 75 can prevent the snow or water from entering between the detection surface 60s and the inner surface 70s of the cover.

[0075] More specifically, the flange 75 extends above the detection device 60 to the Y+ direction side of the end surface 60t on the Y+ direction side of the detection device 60. Therefore, even if snow or water falls downward from the end on the Y+ direction side of the flange 75, the snow or water falls to the Y+ direction side of the detection device 60. This can more firmly prevent snow or water from entering between the detection surface 60s and the back surface 70s of the cover.

[0076] Moreover, if Figure 8 As shown in FIG. 1 , the engagement portion Ep is located on the Y+ direction side relative to the detection surface 60s. Therefore, even if snow or water falls from the engagement hole 75h of the engagement portion Ep to the lower side thereof, the snow or water will fall on the Y+ direction side relative to the detection surface 60s. This can more firmly prevent snow or water from entering between the detection surface 60s and the back surface 70s of the cover.

[0077] Furthermore, if Figure 7 As shown in FIG. 1 , the bracket 50 is provided with a receiving portion 54, which protrudes to a range directly below at least a portion of the engaging protrusion 53. Compared with the two ends of the engaging protrusion 53 in the X direction, the two ends of the receiving portion 54 in the X direction are located outside the X direction. The upper surface 54s of the bottom of the receiving portion 54 is inclined toward the downward side as it moves toward the Y+ direction. Therefore, when snow or water flows from Figure 5 When the end of the X direction of the engaging protrusion 53 shown in the figure falls down, it is also possible to Figure 7 The receiving portion 54 shown blocks the snow or water and guides it to the Y+ direction side. Thus, the snow or water can be drained from the drainage hole 52h to the Y+ direction side of the bracket. Therefore, it is also possible to more firmly prevent the snow or water from entering between the detection surface 60s and the inner surface 70s of the cover.

[0078] like Figure 6 As shown in FIG. 1 , a surrounding portion 57 is provided on the bracket 50. Each surrounding portion 57 has an inner protrusion 57a ​​and an outer protrusion 57b arranged in a direction perpendicular to the Y direction and protruding in the Y-direction. Fig.13 As shown, a flange 75 is provided between the inner protrusion 57a ​​and the outer protrusion 57b of the surrounding portion 57. Thus, since the surrounding portion 57 is provided in addition to the engagement portion Ep, the cover 70 can be mounted on the bracket 50 more stably.

[0079] like Figure 8 , Fig. 9 As shown in FIG. 1 , the lens side guide surface 36s and the cover side guide surface 77s both extend along the insertion imaginary line vL. Fig.10 , Fig.11 As shown, by simply inserting the rod-shaped jig J along the lens-side guide surface 36s and the cover-side guide surface 77s, the tip of the jig J can reach the engagement portion Ep. The jig J can release the engagement of the cover 70 with respect to the bracket 50. Therefore, according to this embodiment, the cover 70 can be removed from the bracket 50 while suppressing the removal of parts other than the cover 70 and the introduction of a special shape for removing the cover as much as possible.
