The panel body has a thickness from the front surface to the back surface. The concealing member is provided in the opening formed in the panel body to equip the optional device and conceals at least the peripheral edge of the opening.

Optional equipment may or may not be equipped. Therefore, when the optional device is equipped, the opening is penetrated through the panel body from the front surface to the back surface by post-processing. The opening formed by post-processing is more likely to deviate from the set position than the opening formed at the same time as molding the panel body.

Therefore, in the panel structure of Patent Document 1, the resin panel corresponding to the panel body has ribs on the back surface, and the lid corresponding to the concealing member has locking claws on the front surface and the back surface. The ribs are integrated on the back surface of the resin panel and extend at a constant height in a direction deviating from the set position. In this panel structure, the height from the front surface of the resin panel to the back surface of the rib is constant even if the opening is displaced, and the locking claws on the front surface and the back surface of the lid hold the front surface of the resin panel and the back surface of the rib. Can be pinched. Thus, the lid can be suitably provided in the opening regardless of the processing accuracy of the opening.

Further, in the panel structure of Patent Document 2, the molded body corresponding to the panel main body has a locking support on the back surface. This locking support is integrated with the base material on the back side of the molded body, is arranged on the side edge of the opening when the base material is provided with an opening, and has a hinge portion that can be bent downward at right angles to the base material. , It consists of a locking surface portion that is integrated with the hinge portion. When the hinge portion is bent downward, the locking surface portion is separated from the hinge portion in a direction parallel to the surface of the panel body and faces the opening side, and a bulging piece portion located in the opening is formed. There is. The hinge portion of the member corresponding to the concealing member is bent, and the tip surface of the bulging piece portion positions the member in a direction parallel to the surface. In this panel structure, even if the opening is displaced, the hinge portion of the locking support is bent downward, and the tip surface of the bulging piece portion in the locking surface portion of the locking support is in a direction parallel to the surface. Since it is held in a fixed position, the locking portion of the member is securely locked to the bulging piece portion. Thus, the member can be suitably provided in the opening regardless of the processing accuracy of the opening.

However, in the panel structure of Patent Document 1, when the opening is displaced, the concealing member, which is a lid, is also displaced in the same direction.

Further, in the panel structure of Patent Document 2, since the hinge portion of the locking support which is a part of the molded body is bent downward, the locking support itself must be bent separately from the rest of the molded body. Must be. Therefore, when positioning in the plane direction with respect to the panel main body, the molded body itself has a complicated structure, the process of forming an opening is complicated, and there is a concern that the manufacturing cost will increase.

The present invention has been made in view of the above-mentioned conventional circumstances, and has a panel structure capable of providing a concealing member at an appropriate position even if the opening is displaced while realizing a reduction in manufacturing cost. Providing is an issue to be solved.

The panel structure of the present invention includes a panel body having a thickness from the front surface to the back surface and a panel body.

The concealing member is characterized in that the hinge portion is bent and the first positioning surface is used for positioning in the first direction.

In the panel structure of the present invention, even if the opening is displaced, the hinge portion of the fixed piece is bent in the first direction parallel to the surface, and the first positioning surface in the fixed portion of the fixed piece is at a fixed position in the first direction. Is kept in. Therefore, the concealing member is positioned in the same first direction as the direction in which the opening is displaced by the first positioning surface. In this way, the concealing member is suitably provided in the opening regardless of the processing accuracy of the opening.

Further, in this panel structure, when the opening is formed by post-processing, the fixing piece of the panel body extends from the back surface in the thickness direction, so that the fixing piece does not get in the way and the opening can be easily formed. Is possible. Further, the hinge portion of the fixed piece, which is a part of the panel body, extends in the thickness direction from the back surface of the panel body before bending, and is bent in the same first direction as the opening is displaced. Therefore, the fixed piece itself can be individually bent separately from the rest of the panel body. Therefore, the panel body itself has a relatively simple structure, and it is not necessary to complicate the process of forming the opening.

Therefore, according to the panel structure of the present invention, it is possible to provide the concealing member at an appropriate position even if the opening is displaced while realizing the reduction of the manufacturing cost.

It is preferable that the panel body and the fixing portion are formed with holding means for holding the bending of the hinge portion and maintaining the distance between the hinge portion and the first positioning surface. In this case, the hinge portion does not return to extend in the thickness direction due to the elastic restoring force, and the distance between the hinge portion and the first positioning surface is maintained. Therefore, the positioning of the concealing member in the first direction is maintained.

It is preferable that the fixing portion is formed with a second positioning surface that intersects the first positioning surface in the thickness direction. Further, it is preferable that the hinge portion of the concealing member is bent and positioned in the thickness direction by the second positioning surface. In this case, the concealing member is also positioned in the thickness direction.

As shown in FIG. 1, the panel structure of the embodiment embodies the present invention by using the instrument panel 3 of the vehicle 1 as the panel body and the bezel 5 as the concealing member. The optional device is a head-up display (HUD) projection device 7.

When the HUD projection device 7 is equipped, the projection image of the HUD projection device 7 is reflected by the front window 9 and visually observed by the driver M on the instrument panel 3, and the projection image thereof is seen by the driver M while driving. As shown in FIG. 2, an opening 3a is formed so that the above can be visually recognized. The opening 3a is formed substantially horizontally. As shown in FIG. 1, the peripheral edge of the opening 3a is concealed by the bezel 5.

In the embodiment, as shown in FIG. 2, a rectangular opening 3a is formed. When the HUD projection device 7 is not equipped, the opening 3a is not formed in the instrument panel 3. Therefore, the opening 3a is penetrated from the front surface to the back surface of the instrument panel 3 by the post-processing punching process. The opening 3a formed in the punching process is about 1 to 2 mm with respect to the set position, and the entire surface is 3b, as compared with the opening formed at the same time as molding the instrument panel 3 due to processing variations during punching. It is easy to shift in the parallel direction. In particular, if the opening 3a deviates from the set position in the first direction D1 where the frontage is narrow and the bezel 5 also deviates from the set position, it becomes difficult for the driver M to visually recognize the projected image of the HUD projection device 7.

As shown in FIG. 3, the instrument panel 3 used in the examples is composed of a skin material 31 made of leather or the like, a foam layer 32 made of foamed polyurethane, and a base material 33 made of synthetic resin. The skin material 31 forms the front surface 3b of the instrument panel 3, and the base material 33 forms the back surface 3c of the instrument panel 3.

As shown in FIG. 2, the base material 33 is formed with two fixing pieces 11 and two engaging convex portions 13. The fixed piece 11 and the engaging convex portion 13 are located in front of the set position of the opening 3a. As shown in FIG. 3, both fixing pieces 11 form a plate shape extending downward from the thickness direction of the instrument panel 3, that is, the base material 33, and extending parallel to the front side 3d of the set position of the opening 3a. There is.

Each fixing piece 11 is composed of a thin-walled hinge portion 35 that is integrated with the base material 33, and a fixing portion 37 that is integrated with the hinge portion 35 and is thicker than the hinge portion 35. Since the hinge portion 35 is formed to be thin, as shown in FIG. 5, it can be bent in the first direction D1 parallel to the surface 3b around the center 35a. As shown in FIG. 3, a columnar engaging hole 39 is formed in the fixing portion 37 in the first direction D1. The lower end of the fixing portion 37 is a first positioning surface 37a. As shown in FIG. 5, the first positioning surface 37a is separated from the hinge portion 35 by a distance L in the first direction D1 by bending the hinge portion 35, faces the opening 3a side, and penetrates the opening 3a. After installation, it is located within the opening 3a. Further, as shown in FIG. 3, the lower side of the front surface 11a of the fixing portion 37 is a second positioning surface 37b. The second positioning surface 37b is orthogonal to the first positioning surface 37a, and as shown in FIG. 5, if the first positioning surface 37a is located in the opening 3a by bending the hinge portion 35, It is orthogonal to the first positioning surface 37a in the thickness direction. Further, as shown in FIGS. 2 and 3, both fixing pieces 11 are formed so that the front surface 11a, the rear surface 11b, the first positioning surface 37a, and the second positioning surface 37b are in the same plane as each other. ..

As shown in FIG. 3, each engaging convex portion 13 is integrally formed with a shaft portion 13a formed in a columnar diameter smaller than the engaging hole 39 of the fixing portion 37 in the fixing piece 11 and the tip of the shaft portion 13a. The umbrella portion 13b is formed to have a diameter larger than that of the engaging hole 39. Each engaging convex portion 13 is formed at a position consistent with the engaging hole 39 when the hinge portion 35 is bent. The engaging hole 39 and the engaging convex portion 13 correspond to the holding means.

As shown in FIGS. 6 and 7, the bezel 5 has a tubular portion 51 inserted into the opening 3a. As shown in FIGS. 4 to 6, a first eaves portion 52 projecting forward in a plate shape is formed at the front upper end of the tubular portion 51. As shown in FIGS. 6 and 7, second eaves 53 projecting laterally and rearward are formed at the lateral upper end and the rear upper end of the tubular portion 51. The first eaves portion 52 has a longer protruding length than the second eaves portion 53.

Further, as shown in FIG. 4, the bezel 5 has a first claw portion 54 projecting forward in a plate shape below the first eaves portion 52. The first claw portion 54 is slightly inclined downward toward the front. A first contact surface 5a extending in the vertical direction is formed between the first eaves portion 52 and the first claw portion 54 in the bezel 5. As shown in FIG. 5, the first contact surface 5a is in contact with the first positioning surface 37a of the fixing portion 37 in each fixing piece 11 in which the hinge portion 35 is bent.

Further, as shown in FIG. 4, a second contact surface 5b extending substantially horizontally is formed on the upper surface of the base of the first claw portion 54. As shown in FIG. 5, the second contact surface 5b is in contact with the second positioning surface 37b of the fixing portion 37 in each fixing piece 11 in which the hinge portion 35 is bent. The distance between the first eaves portion 52 and the first claw portion 54 is slightly smaller than the sum of the thickness of the portion of the instrument panel 3 where the opening 3a is formed and the thickness of the fixing portion 37 of the fixing piece 11. Has been done.

Further, as shown in FIG. 6, the bezel 5 has a second claw portion 55 projecting in a plate shape below the second eaves portion 53. The distance between the second eaves 53 and the second claw 55 is slightly smaller than the thickness of the portion of the instrument panel 3 where the opening 3a is formed.

In this panel structure, after the opening 3a is penetrated, the hinge portion 35 of each fixing piece 11 is bent around the center 35a as shown in FIG. Then, the umbrella portion 13b of each engaging convex portion 13 is bent to pull out the inside of the engaging hole 39, and the umbrella portion 13b is elastic outside the engaging hole 39 with the shaft portion 13a located inside the engaging hole 39. Increase the diameter by restoring force. In this way, the engaging hole 39 and the engaging convex portion 13 hold the bending of the hinge portion 35 and maintain the distance L between the hinge portion 35 and the first positioning surface 37a.

In this state, the bezel 5 is provided in the opening 3a while being slightly bent. Specifically, as shown in FIG. 6, the instrument panel 3 on the front side and the rear side of the opening 3a is sandwiched between the first eaves portion 52 and the first claw portion 54, and the second eaves portion 53 and the second eaves portion 53. The instrument panel 3 on the rear side of the opening 3a and the fixing portion 37 of the fixing piece 11 are sandwiched between the second claw portion 55 and the instrument panel 3 on the rear side.

At this time, as shown in FIG. 5, even if the opening 3a is displaced, the first positioning surface 37a in the fixing portion 37 is maintained at a constant position in the first direction D1. Therefore, the bezel 5 is positioned by the first positioning surface 37a in the same first direction D1 as the direction in which the opening 3a is displaced. In this way, the bezel 5 is suitably provided in the opening 3a regardless of the processing accuracy of the opening 3a.

Further, in this panel structure, when the opening 3a is formed in the punching step, as shown in FIG. 3, the fixing piece 11 of the instrument panel 3 extends from the back surface 3c in the thickness direction, so that the fixing piece 11 Does not get in the way, and the opening 3a can be easily formed. Further, the hinge portion 35 of the fixed piece 11 which is a part of the instrument panel 3 extends in the thickness direction from the back surface 3c of the instrument panel 3 before bending, and the opening 3a is the same as the direction in which the opening 3a is displaced. Is bent into. Therefore, the fixing piece 11 itself can be individually bent separately from the rest of the instrument panel 3. Therefore, the instrument panel 3 itself has a relatively simple structure, and it is not necessary to complicate the process of forming the opening 3a.

Further, in this panel structure, since the engaging convex portion 13 is formed on the instrument panel 3 and the engaging hole 39 is formed on the fixing portion 37, the hinge portion 35 extends in the thickness direction due to the elastic restoring force. The distance L between the hinge portion 35 and the first positioning surface 37a is maintained. Therefore, the positioning of the bezel 5 in the first direction D1 is maintained.

Further, in this panel structure, since the second positioning surface 37b is formed on the fixing portion 37 and the bezel 5 is positioned in the thickness direction by the second positioning surface 37b, the bezel 5 is also positioned in the thickness direction. ..

Therefore, according to this panel structure, the bezel 5 can be provided at an appropriate position of the instrument panel 3 of the vehicle 1 even if the opening 3a is displaced while realizing the reduction of the manufacturing cost, and the user can provide the bezel 5. The HUD system can be suitably used.
