[0004] [Patent Document 1] JP 2005-35364 A [Patent Document 2] JP 2016-187988 A [Patent Document 3] JP 2016-203772 A Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, the through-hole is provided in the ceiling material, which tends to reduce the rigidity of the ceiling material near the through-hole. In order to suppress the reduction in rigidity, for example, the thickness or material of the ceiling material is changed or additional mounting members are provided near the through-hole, which tends to increase costs and weight and reduce productivity.

[0006] In Patent Documents 2 and 3, a part of the in-vehicle devices is likely to be in the field of view of the driver and passenger in the front passenger seat. This tends to narrow the field of view of the passengers and also results in poor appearance.

[0007] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a vehicle structure which makes it easy to increase the rigidity of the area around the through-hole in the ceiling material, makes it easy to widen the field of vision for the driver and passenger in the front passenger seat, and has a good appearance. [Means for solving the problem]

[0008] A vehicle structure according to one aspect of the present invention includes: A ceiling material having a through hole for mounting an inner mirror; an in-vehicle device attached to a surface of an upper portion of the windshield facing the interior of the vehicle; The ceiling material has a front region provided between the through hole and the windshield, the front region has a recess provided so as to be recessed toward at least one of a rearward direction and an upward direction of the vehicle, The vehicle-mounted device has a rear portion disposed close to the recess. Effect of the Invention

[0009] In the above vehicle structure, the front region located forward of the through hole of the ceiling material has a recess, which makes it easy to suppress the decrease in rigidity near the through hole in the ceiling material caused by the through hole. Therefore, the above vehicle structure makes it easy to suppress vibration of the ceiling material caused by the through hole. In the above vehicle structure, since it is not necessary to change the plate thickness or material of the ceiling material or to provide additional mounting members near the through hole in order to suppress the decrease in rigidity, it is easy to suppress an increase in cost, an increase in weight, and a decrease in productivity. In addition, the above vehicle structure can bring the on-vehicle equipment as close as possible to the upper end of the windshield by having the recess in the front region. Therefore, the area of ​​the on-vehicle equipment that is visible to the occupants in the driver's seat and the passenger seat of the vehicle is likely to be reduced. Therefore, the visibility of the occupants is likely to be widened, and the visibility of the occupants is likely to be improved. In addition, the above vehicle structure has a good appearance.

In the following description, "upper", "lower", "front", "rear", "right" and "left" respectively correspond to "upper", "lower", "front", "rear", "right side" and "left side" of the vehicle.

[0012] <<Embodiment>> [Vehicle structure] As shown in Fig. 1, the vehicle structure 1 of the embodiment includes a ceiling material 2 and an on-vehicle device 3. The ceiling material 2 is provided with a through hole 21 for attaching an inner mirror 6. The on-vehicle device 3 is attached to the upper surface of the windshield 9 facing the interior of the vehicle. The surface of the windshield 9 facing the interior of the vehicle may be simply referred to as the inner surface of the windshield 9. One of the features of the vehicle structure 1 of the embodiment is that the ceiling material 2 has a specific recess 24 provided at a specific location, and the on-vehicle device 3 is disposed at a specific position relative to the recess 24.

[0013] [Ceiling material] As shown in Fig. 2, the ceiling material 2 is a member that covers the passenger compartment side of the roof outer panel 100. The vertical cross-sectional view shown in Fig. 2 is a cross-section along the vehicle length and vehicle height. The through-hole 21 provided in the ceiling material 2 is provided forward of a map lamp (not shown). The through-hole 21 is a hole for attaching the inner mirror 6 as described above.

[0014] The inner mirror 6 is a known inner mirror. As shown in FIG. 2, the inner mirror 6 of this example includes a base portion 61, an arm portion 62, and a mirror body portion 63. In FIG. 2, a side view of the inner mirror 6 is shown instead of a cross section for convenience of explanation. The base portion 61 is fixed to the center of the front header panel 110 in the direction along the vehicle width. The front header panel 110 is fixed to the front part of the roof outer panel 100 so as to extend along the vehicle width. The arm portion 62 connects the base portion 61 and the mirror body portion 63. The middle of the arm portion 62 passes between the through hole 21 and the mirror cover 7. The mirror cover 7 covers the base portion 61 by blocking the portion between the opening edge of the through hole 21 and the arm portion 62. The mirror cover 7 is attached to the peripheral portion of the through hole 21. The lower end of the arm portion 62 is exposed to the inside of the vehicle from the ceiling material 2 and the mirror cover 7. The mirror body portion 63 is for allowing the driver to view the rear of the vehicle. The mirror main body 63 includes not only a mirror but also a rearview mirror monitor body equipped with a display. The mirror main body 63 is provided at the lower end of the arm 62. Between the front end of the arm 62 and the windshield 9, a vibration-proof member 8 is attached to suppress vibration of the mirror main body 63 and chatter noise caused by the vibration. The vibration-proof member 8 is a known vibration-proof member. In this example, the vibration-proof member 8 is rod-shaped.

[0015] The ceiling material 2 has a front region 22 between the windshield 9 and the through-hole 21, and a rear region 23 rearward of the through-hole 21. In this example, the front region 22 is configured to intersect with the rear region 23. Unlike this example, the front region 22 may be provided so as to follow the rear region 23. The front end of the front region 22 is connected to the windshield 9. The front region 22 is curved along the windshield 9. That is, the center portion of the front region 22 in the vehicle width is curved so as to be located further forward of the vehicle than the left and right portions.

[0016] The front region 22 has a recess 24 recessed toward at least one of the rear and the upper side of the vehicle. The recess 24 recessed toward at least one of the rear and the upper side of the vehicle means that the recess 24 is recessed only toward the rear of the vehicle, the recess 24 is recessed only toward the upper side of the vehicle, or the recess 24 is recessed toward both the rear and the upper side of the vehicle. The recess 24 in the front region 22 easily suppresses a decrease in rigidity near the through hole 21 due to the through hole 21. The recess 24 in the front region 22 allows the in-vehicle device 3 described later to be brought as close as possible to the upper end of the windshield 9. Therefore, the area of ​​the in-vehicle device 3 that is within the field of view of the driver's seat and the passenger seat is easily reduced. Therefore, the field of view of the occupant is easily widened, and the field of view of the occupant is easily improved. In addition, the vehicle structure 1 has a good appearance. The recess 24 in this example is recessed toward the rear and the upper side of the vehicle.

[0017] The longer the width of the recess 24, the easier it is to suppress the decrease in rigidity. The width of the recess 24 is the length in the direction along the vehicle width. The width of the recess 24 may be, for example, 0.5 times or more, further 0.75 times or more, and particularly 1.0 times or more, the width of the through hole 21. The width of the through hole 21 is the length along the vehicle width of the front edge of the through hole 21. As shown in FIG. 3, the width of the recess 24 in this example is more than 1.0 times the width of the through hole 21, that is, longer than the width of the through hole 21. The width of the recess 24 in this example is longer than the width of the rear part 35 of the in-vehicle device 3. In FIG. 3, the inner mirror 6 is omitted for convenience of explanation.

[0018] The position of the recess 24 along the vehicle width is a position corresponding to the through hole 21. The position corresponding to the through hole 21 means that the recess 24 overlaps the front edge of the through hole 21 in the direction along the vehicle width. When the width of the recess 24 is shorter than the width of the through hole 21, the recess 24 may be located at the center of the through hole 21 in the direction along the vehicle width, or may be located to the right or left of the center. When the width of the recess 24 is longer than the width of the through hole 21 as in this example, the recess 24 overlaps the entire length of the through hole 21 in the direction along the vehicle width. The above-mentioned position of the recess 24 in this example is the center in the direction along the vehicle width. The above-mentioned position of the recess 24 in this example is a position corresponding to the rear part 35 of the in-vehicle device 3 described later.

[0019] The deeper the recess 24, the easier it is to place the rear portion 35 inside the recess 24. The depth of the recess 24 is the distance from a virtual line 24a that spans the opening of the recess 24 to the most distal position of the bottom surface of the recess 24 in a cross section of the recess 24 along the vehicle length and vehicle height shown in FIG. 2. For convenience of explanation, the virtual line 24a is shown in FIG. 2 as a thick two-dot chain line. The virtual line 24a is a curve that connects the front edge and the rear edge of the opening of the recess 24 so as to complement the curve of the part in front of the recess 24 and the part behind the recess 24 in the front region 22. In this example, the depth is preferably such that the rear portion 35 is placed inside the recess 24.

[0020] 1 and 3, the ceiling material 2 of this example has a cutout 25. The cutout 25 is for pulling out a wire harness connected to the camera 31 of the in-vehicle device 3 from the ceiling material 2. The cutout 25 is provided at a position overlapping the cover 34 in the direction along the vehicle width. In this example, the cutout 25 is provided at a position to the left of the recess 24. Even if the cutout 25 is provided, the presence of the recess 24 makes it easy to suppress a decrease in rigidity.

[0021] [In-vehicle equipment] In this example, the in-vehicle device 3 includes a camera 31 and a cover 34, as shown in Fig. 2. For convenience of explanation, Fig. 2 shows a side view of the camera 31 rather than a cross section. The camera 31 measures, for example, the distance to an obstacle such as a leading vehicle ahead. The camera 31 is a known camera. The cover 34 covers the camera 31 from inside the vehicle.

[0022] In this example, the camera 31 is attached to the windshield 9 by a base member 32 and a holding member 33 as shown in FIG. 2. In FIG. 2, for convenience of explanation, the side view, not the cross section, of the base member 32 and the holding member 33 is shown. As shown in FIG. 3, a ceramic line 90 is provided on the inner surface of the windshield 9. The ceramic line 90 is configured by coating with black ceramic. The ceramic line 90 has an attachment area 91 provided in the center of the inner surface of the windshield 9. The attachment area 91 is configured in a trapezoid shape in which the lower base located below the vehicle is shorter than the upper base located above the vehicle. The base member 32 shown in FIG. 2 is fixed to the attachment area 91 shown in FIG. 3 by adhesive or double-sided tape. The base member 32 is a known base member. The holding member 33 is a member that holds the camera 31. The holding member 33 is a known holding member. The camera 31 is detachably attached to the holding member 33. The holding member 33 that holds the camera 31 is detachably attached to the base member 32. The holding member 33 is attached to the base member 32 attached to the windshield 9, and the camera 31 attached to the holding member 33 is thereby attached to the windshield 9.

[0023] The cover 34 is detachably attached to the base member 32. The method of attaching the cover 34 to the base member 32 is not particularly limited. The cover 34 may be attached to the base member 32 by sliding the cover 34 along the inner surface of the windshield 9 in a direction from the front and below the windshield 9 toward the rear and upper end of the windshield 9. Alternatively, the cover 34 may be attached to the base member 32 by moving the cover 34 from the bottom to the top of the vehicle toward the base member 32 and fitting it into the base member 32.

[0024] The in-vehicle device 3 has a rear portion 35 arranged close to the recessed portion 24. Arrangement close to the recessed portion 24 means that the rear portion 35 may be arranged inside the recessed portion 24 or outside the recessed portion 24 as long as a minimum clearance is provided between the in-vehicle device 3 and the ceiling material 2. The rear portion 35 is arranged inside the recessed portion 24 including a case where the rear portion 35 is arranged closer to the bottom surface of the recessed portion 24 than the position where the rear portion 35 is in contact with the imaginary line 24a in the cross section of the recessed portion 24 along the vehicle length and vehicle height shown in FIG. 2, and a case where the rear portion 35 is arranged in a position where the rear portion 35 is in contact with the imaginary line 24a. The rear portion 35 is arranged outside the recessed portion 24 means a case where the minimum clearance exceeds the depth of the recessed portion 24 and the rear portion 35 is arranged farther from the bottom surface of the recessed portion 24 than the position where the rear portion 35 is in contact with the imaginary line 24a. In this case, the rear portion 35 is arranged at a position where the sum of the distance between the rear portion 35 and the imaginary line 24a and the depth corresponds to the minimum clearance. The minimum clearance is the smallest distance between the in-vehicle device 3 and the ceiling material 2 when the vehicle is not vibrating and the in-vehicle device 3 and the ceiling material 2 do not come into contact with each other when the vehicle vibrates. The minimum clearance differs depending on the vehicle model. The rear part 35 of the in-vehicle device 3 is the part of the in-vehicle device 3 that is closest to the ceiling material 2. As shown in FIG. 3, the rear part 35 of the in-vehicle device 3 in this example is configured to be divided into two parts at the center of the rear part of the cover 34 in the direction along the vehicle width. In this example, the rear part 35 is disposed inside the recess 24. The width of the rear part 35 is equal to or less than the width of the recess 24.

[0025] As shown in Figs. 2 and 3, the in-vehicle device 3 of this example has a recess 36 provided so that the in-vehicle device 3 and the vibration-proof member 8 do not interfere with each other when the rear part 35 is placed close to the recess 24. The recess 36 of this example is provided at the rear of the cover 34. The recess 36 is provided between the two rear parts 35 as shown in Fig. 3. When the recess 36 is viewed from below as shown in Fig. 3, the shape of the recess 36 is U-shaped. The rear of the recess 36 is open. The rear opening of the recess 36 is covered by the front region 22 of the ceiling material 2. The recess 36 surrounds the left, right, and front of the vibration-proof member 8 without surrounding the rear of the vibration-proof member 8. The left, right, and front of the vibration-proof member 8 are surrounded by the recess 36, and the rear of the vibration-proof member 8 is covered by the front region 22, so that the vibration-proof member 8 is difficult to see from the outside, and therefore looks good.

[0026] Unlike this example, the in-vehicle device 3 may include, instead of the camera 31, a laser radar, a millimeter wave radar, an ultrasonic sensor, an in-vehicle ETC (Electronic Toll Collection System), a Global Positioning System (GPS), and a humidity sensor, for example.

[0027] The present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims. [Explanation of symbols]
