Japanese Patent Application Publication No. 2017-114443

The inventors of the present invention focused on a configuration in which the in-vehicle display device is arranged so that the display screen faces the driver's seat in order to improve the driver's visibility of the in-vehicle display device. In this case, the pair of left and right support brackets do not have a symmetrical configuration. For example, in the case of a right-hand drive vehicle, the distance between the fastening position on the right side (the fastening position of the support bracket) and the instrument panel reinforcement is greater than the distance between the fastening position on the right side of the housing of the in-vehicle display device (the fastening position of the support bracket) and the instrument panel reinforcement. The distance between instrument panel reinforcement becomes longer. Therefore, the support bracket fastened to the left side of the housing is longer than the support bracket fastened to the right side of the housing. That is, the overhang on the left side of the housing becomes larger, and the support bracket becomes longer accordingly.

In such a structure where the support bracket has to be long, if a support bracket with the same shape as before (a support bracket with the same shape as before but only longer) is applied, the in-vehicle display device It is difficult to obtain sufficient support rigidity, and there is a possibility that the rigidity and durability cannot be sufficiently improved.

The present invention has been made in view of this point, and an object of the present invention is to provide a support structure for a vehicle-mounted display device that can provide sufficient support rigidity.

The solution of the present invention for achieving the above-mentioned object is based on a support structure for an on-vehicle display device disposed at the center of a dashboard of a vehicle in the width direction of the vehicle. The support structure for the in-vehicle display device is provided with a pair of left and right support brackets that connect the instrument panel reinforcement disposed inside the dashboard and the right and left sides of the in-vehicle display device, respectively. One of the support brackets has at least one of its upper and lower edges in a curved shape when viewed from the vehicle width direction, and the bracket width in a direction perpendicular to the tangent of the curved line. It is characterized in that its dimensions gradually increase toward the joint with the instrument panel reinforcement.

Due to this specific matter, the rigidity of the support bracket itself is increased, and a large joint range between the support bracket and the instrument panel reinforcement can be ensured, and the support rigidity of the support bracket can also be increased. As a result, sufficient support rigidity for the in-vehicle display device can be obtained.

In the present invention, as a support bracket for supporting an in-vehicle display device on an instrument panel reinforcement, at least one of the upper edge and the lower edge when viewed from the vehicle width direction has a curved shape, and the shape is perpendicular to the tangent of the curved line. The width of the bracket in this direction gradually increases toward the joint with the instrument panel reinforcement. Thereby, sufficient support rigidity of the in-vehicle display device can be obtained.

Embodiments of the present invention will be described below based on the drawings. In this embodiment, a case will be described in which a support structure for a vehicle-mounted display device according to the present invention is applied to a right-hand drive vehicle.

-Support structure for in-vehicle display device-
1 to 3 show a support structure for a vehicle-mounted display device 1 according to this embodiment. FIG. 1 is a front view showing the periphery of the in-vehicle display device 1. As shown in FIG. FIG. 2 is a perspective view (with the dashboard omitted) schematically showing the support structure of the in-vehicle display device 1. FIG. 3 is a plan view schematically showing the support structure of the in-vehicle display device 1 (in FIG. 3, the dashboard 5 is shown by a virtual line). In these figures, arrow FR indicates the front direction of the vehicle body, arrow RR indicates the rear direction of the vehicle body, arrow HR indicates the right side in the vehicle width direction, and arrow HL indicates the left side in the vehicle width direction.

As shown in these figures, the in-vehicle display device 1 is supported by the instrument panel reinforcement 4 at both left and right sides 12 and 13 of the housing 11 via support brackets 2 and 3, respectively. The in-vehicle display device 1 includes a display screen 14 configured with a liquid crystal display or an organic EL (Electro Luminescence) display, and a casing that houses various electronic components that configure an image generation device that generates images to be displayed on the display screen 14. It is equipped with a housing 11 as a body, and can display images as a car navigation device, images as an audio device, etc.

The in-vehicle display device 1 according to the present embodiment is arranged so that the display screen 14 faces the driver's seat side (for example, at the rear of the vehicle) in order to improve the driver's visibility of the in-vehicle display device 1. (It is arranged so that it faces the driver's seat by a few dozen degrees.) Therefore, compared to the distance between the fastening position (the fastening position of the support bracket 2) on the right side 12 of the respective side parts 12 and 13 of the housing 11 of the in-vehicle display device 1 and the instrument panel reinforcement 4, the left side 13 The distance between the fastening position (the fastening position of the support bracket 3) and the instrument panel reinforcement 4 becomes longer. Therefore, the support bracket 3 fastened to the left side 13 of the housing 11 is longer than the support bracket 2 fastened to the right side 12 of the housing 11. That is, the overhang at the left side 13 of the housing 11 becomes larger, and the support bracket 3 (the support bracket fastened to the left side 13 of the housing 11) becomes longer.

-Structure of support bracket-
Each support bracket 2, 3 will be explained below. Here, the support bracket that connects the right side 12 of the housing 11 of the in-vehicle display device 1 and the instrument panel reinforcement 4 is referred to as the right side support bracket 2, and the support bracket that connects the right side 12 of the housing 11 of the in-vehicle display device 1 and the instrument panel reinforcement 4 is referred to as the right side support bracket 2. The support bracket connecting these will be referred to as the left side support bracket 3.

As shown in FIG. 3, the right side support bracket 2 includes a base member 21 and a support plate 22.

The base member 21 of the right side support bracket 2 has a U-shaped cross section. This base member 21 includes a front joint part 23, a central part 24, and a rear fastening part 25. The front joint portion 23 extends in the vertical direction, and its lower edge is welded to the outer surface of the instrument panel reinforcement 4. The center portion 24 is continuous with the upper end of the front joint portion 23 and slopes upward toward the rear of the vehicle body. The rear fastening portion 25 is continuous with the rear end of the center portion 24 and extends inward in the vehicle width direction. This rear fastening portion 25 is formed with a bolt hole (not shown) that extends through the vehicle body in the longitudinal direction.

The support plate 22 of the right support bracket 2 includes a first plate portion 26 and a second plate portion 27. The first plate portion 26 has a flat plate shape, and is superimposed on the right side portion 12 of the housing 11 and fastened with bolts (the bolts are not shown). The second plate portion 27 is continuous with the front portion of the first plate portion 26 and extends outward in the vehicle width direction. This second plate portion 27 is formed with a bolt hole (not shown) that extends through the vehicle body in the longitudinal direction.

Then, with the bolt holes of the second plate part 27 and the bolt holes of the rear fastening part 25 aligned, the second plate part 27 and the rear fastening part 25 are overlapped, and each bolt hole is aligned with the bolt hole of the second plate part 27 and the rear fastening part 25. Both 25 and 27 are bolted together by passing a bolt (not shown) through them.

In this manner, the right side portion 12 of the housing 11 of the in-vehicle display device 1 is supported by the instrument panel reinforcement 4 by the right side support bracket 2.

As shown in FIGS. 2 and 3, the left side support bracket 3 includes a base member 31 and a support plate 32. As shown in FIGS. FIG. 4 is a perspective view (a perspective view seen from the left side in the vehicle width direction) showing the base member 31 of the left side support bracket 3. Further, FIG. 5 is a sectional view taken along the line VV in FIG. 4.

As shown in these figures, the base member 31 of the left side support bracket 3 has a U-shaped cross section that is open toward the inside in the vehicle width direction. Specifically, this base member 31 includes a vertical plate portion 33 extending in a direction crossing the vehicle width direction, and an upper flange portion 34 extending inward in the vehicle width direction from the upper end of the vertical plate portion 33. , and a lower flange portion 35 extending inward in the vehicle width direction from the lower end of the vertical plate portion 33. A plurality of openings 33c are formed in the vertical plate portion 33 in order to reduce the weight of the base member 31.

One of the features of the base member 31 of the left side support bracket 3 is that when the base member 31 is viewed from the vehicle width direction (see FIG. 4), The ridgeline portion between the flange portion 34) 33a and the lower end edge of the vertical plate portion 33 (the ridgeline portion between the vertical plate portion 33 and the lower flange portion 35) 33b are both curved. Specifically, these edges 33a, 33b are curved so that the angle of inclination gradually decreases toward the rear of the vehicle body (curved from an upward direction to a horizontal direction gradually toward the rear of the vehicle body). The curvature of this curve can be set arbitrarily. Thereby, the left side support bracket 3 connects the left side portion 13 of the housing 11 of the in-vehicle display device 1 and the instrument panel reinforcement 4 while avoiding interference with peripheral parts (not shown).

In addition, the bracket width dimension in the direction perpendicular to the tangent line of these two edges 33a, 33b (for example, the direction along the line V-V in FIG. 4) gradually increases toward the joint with the instrument panel reinforcement 4. are doing. That is, the dimension t2 (bracket width dimension at the front end portion of the base member 31) is set larger than the dimension t1 (bracket width dimension at the rear end portion of the base member 31) in FIG. It gradually becomes larger as you move towards it.

In addition, at the front end of the base member 31, both the upper flange 34 and the lower flange 35 slightly protrude from the edge (projection) 36a of the vertical plate 33 (project diagonally downward). The edge 36a of the vertical plate part 33 and the respective protrusions 34a, 35a are arranged so as to surround the outer surface of the instrument panel reinforcement 4. The portions 34a and 35a are welded to the outer surface of the instrument panel reinforcement 4.

Further, as shown in FIG. 3, the upper flange portion 34 of the base member 31 has a width dimension (length dimension in the vehicle width direction) at the rear side of the center portion in the front-rear direction than at the center portion in the front-rear direction. It is set shorter than the width dimension at the front part. Therefore, in the area rearward of the central portion in the front-rear direction, the width dimension of the lower flange portion 35 (length dimension in the vehicle width direction) is longer than the width dimension of the upper flange portion 34. It has become. Bolt holes 35b, 35b are formed in two locations (two locations spaced apart from each other by a predetermined distance in the front-rear direction) of the lower flange portion 35 so as to extend vertically through the bolt holes 35b.

The support plate 32 of the left side support bracket 3 includes a first plate part 36 and a second plate part 37. The first plate portion 36 has a flat plate shape, and is superimposed on the left side portion 13 of the housing 11 and fastened with bolts (the bolts are not shown). The second plate portion 37 is continuous with the lower end of the first plate portion 36 and extends outward in the vehicle width direction. Two bolt holes (not shown) are formed in the second plate portion 37 at two locations (two locations spaced apart from each other by a predetermined distance in the front-rear direction) that extend vertically through the bolt holes.

Then, with the bolt holes of the second plate part 37 and the bolt holes 35b, 35b of the lower flange part 35 aligned, the second plate part 37 and the lower flange part 35 are overlapped (for example, The lower flange portion 35 is superimposed on the upper side of the second plate portion 37), and bolts are inserted through the respective bolt holes, thereby bolting the two plate portions 35 and 37 together.

In this way, the left side support bracket 3 supports the left side portion 13 of the housing 11 of the in-vehicle display device 1 on the instrument panel reinforcement 4.

As shown in FIGS. 1 and 3, the shape of the dashboard 5 around the location where the in-vehicle display device 1 is arranged is such that it covers the outer periphery of the housing 11 of the in-vehicle display device 1. As shown in FIGS. That is, the upper plate part 51 is close to the upper surface of the housing 11 and covers the upper side of the upper surface, the lower plate part 52 is close to the lower surface of the housing 11 and covers the lower side of the lower surface, and the lower plate part 52 is close to the right side part 12 of the housing 11. A right plate part 53 covers the right side of the right side part 12, and a left plate part 54 close to the left side part 13 of the housing 11 covers the left side of the left side part 13. As mentioned above, the left side support bracket 3 is longer than the right side support bracket 2 because the in-vehicle display device 1 is arranged so that the display screen 14 faces the driver's seat side. Compared to the length dimension of the right panel section 53 of the dashboard 5 (the length dimension in the direction along the right section 12 of the housing 11), the length dimension of the left panel section 54 of the dashboard 5 (the length dimension in the direction along the right section 12 of the housing 11) 13) is longer.

-Effects of embodiment-
With the above configuration, the present embodiment can achieve the following effects.

As described above, when the in-vehicle display device 1 is arranged so that the display screen 14 faces the driver's seat side, there is a gap between the fastening position on the left side 13 of the housing 11 (the fastening position of the left side support bracket 3) and the instrument panel reinforcement 4. As the distance becomes longer, the length of the left side support bracket 3 tends to become longer, but in this embodiment, the shape of the upper edge 33a and the lower edge 33b of the base member 31 of the left side support bracket 3 is curved, In addition, the bracket width dimension in the direction orthogonal to the tangent to the curve gradually increases toward the joint with the instrument panel reinforcement 4. Therefore, the rigidity of the left side support bracket 3 itself is increased, and a large joining range (for example, arc welding range) between the left side support bracket 3 and the instrument panel reinforcement 4 can be secured, and the left side support bracket 3 It is possible to obtain high support rigidity. As a result, sufficient support rigidity of the in-vehicle display device 1 can be obtained, and the sense of rigidity and durability can be sufficiently improved.

Furthermore, in the support structure of the conventional general in-vehicle display device a shown in FIGS. 6 to 8, base members e1, (f1 ) and the support plates e2, (f2) are bolted together using bolt holes penetrating the vehicle body in the longitudinal direction. In this case, a space is required to insert a tool (a tool for bolt fastening) before and after the overlapping portion of the base member e1, (f1) and the support plate e2, (f2), and for this reason, the base member e1, , (f1) tended to protrude outward in the vehicle width direction. Along with this, the dimension in the vehicle width direction (dimension t3 in FIG. 6) of the dashboard outside the display screen h of the in-vehicle display device a (the dashboard that forms the frame of the display screen h: also referred to as the center cluster part) has increased. This led to a deterioration in appearance.

In contrast, in this embodiment, the base member 31 of the left side support bracket 3 and the support plate 32 are bolted together using bolt holes penetrating in the vertical direction. In this case, the space into which the tool for bolting the base member 31 and the support plate 32 is inserted will be provided above and below the overlapping portion of these members 31 and 32, so that There is no need for a space for inserting tools into the space. Therefore, it is possible to reduce the extent to which the base member 31 and the support plate 32 of the left side support bracket 3 extend outward in the vehicle width direction. Accordingly, the dimension in the vehicle width direction (dimension t4 in FIG. 1) of the dashboard 5 outside the display screen 14 of the in-vehicle display device 1 (the dashboard configuring the frame of the display screen 14) can be reduced. A good appearance can be obtained.
