<<Operations>>

The radar mounting structure 100 of the above-described embodiment according to the present invention is basically configured as described above. Next, operations and effects of the radar mounting structure 100 will be described with reference to FIGS. 1 to 4B, in comparison with a comparative example of a radar mounting structure 1000 mounted on an ordinary vehicle, illustrated in FIG. 4A.

FIG. 4A is a component part correlation diagram of the radar mounting structure 1000 of a comparative example illustrating an attachment relationship of radar component parts mounted on an ordinary vehicle. FIG. 4B is a diagram illustrating an example of the radar mounting structure 100 of the above-described embodiment according to the present invention, and is a component part correlation diagram illustrating an attachment relationship of radar component parts. Black lines in FIGS. 4A and 4B each represent a fix relationship between elements. In addition, an overlap of rectangular frames represents a conceptual inclusion relationship of elements.

As illustrated in FIGS. 4A and 4B, in both cases of the radar mounting structure 1000 of the comparative example and the radar mounting structure 100 of the above-described embodiment according to the present invention, the lamp housing 3 of the headlamp assembly 10 is fixed to the wheelhouse member 13 and to the bulkhead 14 of the vehicle body 1. The light source 2, in both cases of the comparative example and the above-described embodiment according to the present invention, is housed in a housing made up of the lamp housing 3 and the lens 4.

In addition, the corner upper beam 11, in both cases of the comparative example and the above-described embodiment according to the present invention, is fixed to the lamp housing 3 and to the vehicle body 1. Further, the bumper face B, in both cases of the comparative example and the above-described embodiment according to the present invention, is fixed to the corner upper beam 11.

As illustrated in FIG. 4A, a radar 500 of the radar mounting structure 1000 of the comparative example is fixed to a radar bracket 700, which is attached to the headlamp assembly 10.

On the other hand, the radar 5 of the radar mounting structure 100 of the embodiment according to the present invention is attached to the corner upper beam 11, as illustrated in FIGS. 3 and 4B.

Therefore, for the radar 5 of the radar mounting structure 100 of the embodiment according to the present invention, there is no need of the radar bracket 700 dedicated to attaching the radar 500 to the headlamp assembly 10 in the radar mounting structure 1000 of the comparative example illustrated in FIG. 4A. Therefore, the radar mounting structure 100 of the embodiment according to the present invention makes it possible to reduce the number of component parts, the number of assembling person-hours, and thus the cost. In addition, the accuracy of the attachment of the radar 5 to the vehicle body 1 can be improved by the radar 5 being directly attached to the corner upper beam 11.

In addition, as illustrated in FIG. 4A, a radar cover 600 of the radar mounting structure 1000 of the comparative example is attached to the headlamp assembly 10.

On the other hand, the radar cover 6 of the radar mounting structure 100 of the embodiment according to present invention is attached to the corner upper beam 11 and to the lens 4, as illustrated in FIGS. 3 and 4B. Therefore, the radar cover 6 of the embodiment according to the present invention is rigidly fixed and the accuracy of the attachment of the radar cover 6 to the vehicle body 1 is improved, compared to the radar cover 600 of the comparative example. Moreover, as the accuracy of the attachment of the radar cover 6 to the bumper face B is also improved, the accuracy of gap setting and step setting of the radar cover 6 as a design component part is improved, leading to an improvement in the appearance.

In addition, regarding the positional relationship between the radar cover 6 and the radar 5, the radar cover 6 and the radar 5 are assembled to the same corner upper beam 11, leading to an improvement in the performance and accuracy of the radar 5.

As described above, as illustrated in FIG. 2 or FIG. 3, the radar mounting structure 100 of the embodiment according to the present invention includes the corner upper beam 11, the lamp housing 3 that houses the light source 2 inside and that is attached to the vehicle-body upper side of the corner upper beam 11, and the radar 5 configured to detect an object that is present ahead on the vehicle width direction outer side of the vehicle C. The radar 5 is disposed in front of the lamp housing 3 so as to overlap with the lamp housing 3 when viewed in the front-rear direction, and is fixed to the corner upper beam 11.

According to such a configuration, the radar 5 is disposed so as to overlap with the lamp housing 3 when viewed in the front-rear direction, in front of a portion of the lamp housing 3 at which portion the light source 2 is not disposed. Therefore, the radar 5 does not block the light emitted from the light source 2. The radar 5 is fixed to the corner upper beam 11 of the vehicle body 1, and thus the radar 5 is rigidly attached to the vehicle body 1 without positional deviation, leading to an improvement in the accuracy of the attachment position with respect to the vehicle body 1. Therefore, the present invention makes it possible to eliminate a bracket dedicated to attaching the radar 5. Accordingly, in association with the integration of the component parts, it is possible to reduce the cost by reducing the number of component parts, the number of assembling person-hours, and the number of manufacturing management person-hours and to improve the appearance of the light source.

[First Modification]

Heretofore, an embodiment according to the present invention have been described in detail with reference to the drawings. However, the present invention is not limited to the above-described embodiment, and can be appropriately modified without departing from the gist of the present invention.

FIG. 5 is a schematic longitudinal cross-sectional view illustrating a main part of a radar mounting structure 100A, which is a first modification of the radar mounting structure 100 of the above-described embodiment according to the present invention.

The lens 4 described in the above-described embodiment (see FIGS. 2 and 3) is not limited to a lens that covers only one type of light source 2 (for example, a headlamp). As illustrated in FIG. 5, a lens 4A may cover a first light source 21 made up of a headlamp, and may cover a second light source 22 made up of signal lamps, non-limiting examples of which include a turn signal lamp and a position lamp.

In this case, the second light source 22 is disposed rearwardly of and at a higher position than the radar 5. For this reason, the light emitted from the second light source 22 is not blocked by the radar 5.

In addition, a lamp housing 3A may house a plurality of light sources 2, such as the first light source 21 and the second light source 22.

In this case, a radar cover 6A disposed on the front side of the lens 4A is made up of an opaque member disposed in front of the radar 5 to cover the radar 5. Therefore, the radar cover 6A is capable of preventing the radar 5 from being visually recognized from the outside of the vehicle, leading to an improvement in the appearance.

Also in such a configuration, in the radar mounting structure 100A, the corner upper beam 11 is capable of rigidly holding the radar 5 and the lamp housing 3A.

[Second Modification]

FIG. 6 is a schematic exploded perspective view illustrating a main part of a radar mounting structure 100B, which is a second modification of the radar mounting structure 100 of the above-described embodiment according to the present invention. FIG. 7 is a schematic longitudinal cross-sectional view illustrating a main part of the radar mounting structure 100B.

The radar cover 6 described in the above embodiment (see FIG. 2) as covering the radar 5 is not limited to those that cover only the radar 5. As illustrated in FIGS. 6 and 7, a radar cover 6B covering the radar 5 may be configured to serve also as a lens covering the light sources 2.

In this case, the radar cover 6B includes, for example, a radar cover portion 61B covering the radar 5 provided in the radar bracket portion 12, and light source lens cover portions 62B covering the light sources 2 provided in a headlamp assembly 10B. The radar cover 6B is integrally formed by two-color molding, joining, or bonding the radar cover portion 61B made of an opaque resin and the light source lens cover portions 62B each made of a transparent resin, and covers, as a single member, the radar 5 and the light sources 2.

The radar cover portion 61B is disposed in front of the radar bracket portion 12 and the radar 5. The light source lens cover portions 62B are disposed respectively on the left and right of the radar cover portion 61B, and are disposed respectively in front of the first light source 21 and the second light source 22 to cover them.

In addition, two types of light sources 2 including the first light source 21 (headlamp) and the second light source 22 (signal lamp(s)) are installed in the headlamp assembly 10B. The entire front side of the headlamp assembly 10B is covered with the radar cover 6B disposed in front of the first light source 21 and the second light source 22 with the corner upper beam 11 interposed therebetween. The first light source 21 is disposed at a position spaced apart inward in the vehicle width direction from the radar bracket portion 12 and the radar 5, in a front view. The signal lamps of the second light source 22 are disposed respectively at a position spaced apart upward from the radar bracket portion 12 and the radar 5 and at a position spaced apart outward in the vehicle width direction, in a front view.

In addition, a lamp housing 3B includes a light source housing portion 32B that houses the light sources 2 and a housing portion 33B that houses the radar bracket portion 12 holding the radar 5.

According to the second modification of the above-described embodiment according to the present invention, the light source lens cover portions 62B of the radar cover 6B is configured to serve also as lamp lenses that that cover the light sources 2. Therefore, a cover dedicated to the radar 5 is not necessary, leading to a reduction in the number of component parts and the number of assembling person-hours. As the radar cover 6B is configured to serve also as the lenses that cover the light sources 2 and thus the radar cover 6B is rigidly attached to the vehicle body 1 without positional deviation, the accuracy in the attachment position with respect to the vehicle body 1 is improved.

[Third Modification]

FIG. 8 is a schematic exploded perspective view illustrating a main part of a radar mounting structure 100C, which is a third modification of the radar mounting structure 100 of the above-described embodiment according to the present invention. FIG. 9 is a schematic diagram illustrating the radar mounting structure 100C.

Regarding the radar 5 of the above-described embodiment, the radar cover 6 is not limited to those that cover only the radar 5 as illustrated in FIG. 2. As illustrated in FIG. 8 or FIG. 9, the light sources 2 provided in a headlamp assembly 10C of the radar mounting structure 100C may include the first light source 21 and the second light source 22, the first light source 21 and the second light source 22 may be respectively covered with a first light source lens 41C and a second light source lens 42C, and the radar 5 may be covered with the second light source lens 42C.

In addition, the first light source 21 may be a headlamp, and the second light source 22 may be signal lamps.

In this case, in the headlamp assembly 10C, the first light source 21 of the headlamp and the second light source 22 including signal lamps such as a position lamp and a turn signal lamp are installed.

The first light source 21 is made up of a halogen lamp, a discharge (HID) lamp, or an LED. The first light source 21 is covered by the first light source lens 41C disposed in front of the first light source 21.

The second light source 22 is made up of, for example, LEDs. The second light source 22 is covered with the second light source lens 42C with the corner upper beam 11 and the radar 5, which are disposed on the front side, interposed between the second light source 22 and the second light source lens 42C.

The first light source 21 and the second light source 22 are housed in a lamp housing 3C. A lens 4C includes: the first light source lens 41C covering the front side of the first light source 21; and the second light source lens 42C covering the front side of the second light source 22 and the radar 5. Therefore, the second light source lens 42C is disposed in front of the second light source 22 and the radar 5.

According to the third modification of the above-described embodiment according to the present invention, the second light source lens 42C serves also as a radar cover covering the radar 5. Therefore, a cover dedicated to the radar is not necessary. Accordingly, the number of component parts and the number of component parts management person-hours are reduced, leading to a reduction in the cost.

In addition, the maintenance of the radar 5 can be conducted by simply detaching the second light source lens 42C, leading to an improvement in the ease of maintenance at the time of replacing the radar 5.

In addition, in general, when the headlamp, which is the first light source 21, is detached from the lamp housing 3C or from the first light source lens 41C, so-called aiming for calibrating the orientation of the main optical axis in the light distribution characteristics is needed in order to cause the headlamp to operate correctly. This takes time and effort.

On the other hand, the radar 5 of the third modification of the above-described embodiment according to the present invention is covered by the second light source lens 42C covering the signal lamp(s), which is the second light source 22. Therefore, a maintenance can be easily conducted by detaching the cover (second light source lens 42C) of the signal lamp(s). Therefore, in the event of conducting the maintenance of the radar 5, the radar 5 can be detached by simply detaching the signal lamp housing. Therefore, it is not necessary to detach the first light source lens 41C of the headlamp. Therefore, it is not necessary to conduct the aiming which is to be conducted in the event of detaching the headlamp, and the maintenance is facilitated.

[Fourth Modification]

FIG. 10 is a schematic longitudinal cross-sectional view illustrating a main part of a radar mounting structure 100D, which is a fourth modification of the radar mounting structure 100 of the above-described embodiment according to the present invention.

As in the radar mounting structure 100D of the fourth modification of the above-described embodiment according to the present invention illustrated in FIG. 10, a radar cover 6D may be fixed to a lamp housing 3D separately from a lens 4D of the light source 2 provided in a headlamp assembly 10D of the radar mounting structure 100D.

In this case, the lens 4D serving also as a light source cover includes: a first light source lens (not illustrated) covering the first light source 21 (not illustrated); and a second light source lens 42D covering the second light source 22. The first light source lens (not illustrated) does not extend to reach a lower end of a lower housing portion 33D, and is fixed to the lower housing portion 33D disposed to extend downward from an upper housing portion 32D. The second light source lens 42D is attached to the upper housing portion 32D to cover the front side of the upper housing portion 32D.

The radar 5 may be fixed to the lamp housing 3D with a corner upper beam 11D interposed between the radar 5 and the lamp housing 3D, or may be directly fixed to the lamp housing 3D.

In addition, the radar cover 6D is fixed to the lamp housing 3D, and is fixed in front of the lower housing portion 33D so as to cover the radar 5. The radar cover 6D is provided to be adjacent to a lower side of the second light source lens 42D in a longitudinal cross-sectional view.

As described above, the radar cover 6D is fixed to the lamp housing 3D with no relation to the lens 4D for the light source 2, leading to an improvement in the accuracy of the attachment of the radar cover 6D with respect to the vehicle body (not illustrated) and leading to a reduction in the number of component parts.
