Description

  The present invention relates to a panel structure.

  Patent Documents 1 and 2 disclose a conventional panel structure. These panel structures include a panel body and a concealing member. The panel body has a thickness from the front surface to the back surface. The concealing member is provided in an opening formed for mounting an optional device in the panel main body, and conceals at least a periphery of the opening.

  Optional equipment may or may not be equipped. Therefore, when the optional device is provided, the opening is penetrated from the front surface to the rear surface of the panel main body by post-processing. The opening formed by the post-processing is more likely to deviate from the set position than the opening formed simultaneously with the molding of the panel body.

  For this reason, in the panel structure of Patent Document 1, the resin panel corresponding to the panel main body has a rib on the back surface, and the lid corresponding to the concealing member has locking claws on the front surface and the back surface. The rib is integral with the back surface of the resin panel and extends at a certain height in a direction deviating from the set position. In this panel structure, even if the opening is displaced, the height from the front surface of the resin panel to the back surface of the rib becomes constant, and the locking claws on the front surface and the back surface of the lid connect the front surface of the resin panel and the back surface of the rib. I can pinch it. Thus, regardless of the processing accuracy of the opening, the lid can be suitably provided in the opening.

  Further, in the panel structure of Patent Document 2, a molded body corresponding to the panel main body has a locking support on the back surface. The locking support is formed integrally with the base material on the back side of the molded body, and is disposed at a side edge of the opening when the opening is provided in the base material, and has a hinge portion that can be bent downward perpendicular to the base material. , And a locking surface that is integral with the hinge. When the hinge portion is bent downward, the locking surface portion is formed with a bulging piece portion that faces away from the hinge portion in a direction parallel to the surface of the panel body, faces the opening side, and is located in the opening. I have. The member corresponding to the concealing member has its hinge portion bent and positioned in the direction parallel to the surface by the distal end surface of the bulging piece portion. In this panel structure, even if the opening is displaced, the hinge portion of the locking support is bent downward, and the tip end surface of the bulging piece in the locking surface of the locking support is in a direction parallel to the surface. Since the fixed position is maintained, the locking portion of the member is securely locked to the bulging piece. Thus, regardless of the processing accuracy of the opening, the member can be suitably provided in the opening.

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

  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. Therefore, when performing positioning in the surface direction with respect to the panel body, the molded body itself has a complicated structure or a process of forming an opening becomes complicated, and there is a concern that manufacturing costs may increase.

  The present invention has been made in view of the above-described conventional circumstances, and realizes a reduction in manufacturing cost, and even when an opening is displaced from a set position due to formation by post-processing, the concealing member is positioned at an appropriate position. It is an object to provide a panel structure that can be provided.

A panel structure comprising: a concealing member that is provided in an opening that is penetrated by post-processing from the front surface to the back surface to equip the panel body with an optional device, and conceals at least a peripheral edge of the opening.
The panel body has an engagement portion provided on the back surface and concealed by the panel body located in a first direction parallel to the surface from the opening,
The concealing member is insertable from the opening, and has an engaged portion that engages with the engaging portion when the concealing member moves in the first direction,
The concealing member is characterized in that the positioning in the first direction with respect to the panel main body is performed by the engagement between the engaging portion and the engaged portion.

  In the panel structure of the present invention, even if the opening is displaced, the engaged portion of the concealing member is engaged with the engaging portion of the panel main body, and these are kept at a fixed position in the first direction. For this reason, the concealing member is positioned in the first direction that is the same as the direction in which the opening shifts. Thus, regardless of the processing accuracy of the opening, the concealing member is suitably provided in the opening.

  Further, in this panel structure, when the opening is formed by post-processing, the engaging portion of the panel main body is concealed by the panel main body at a position outside the opening, so that the opening can be easily formed. Therefore, the panel body itself has a relatively simple structure, and there is no need to complicate the step 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 when the opening is deviated from the set position due to the formation by the post-processing, while realizing a low manufacturing cost.

  It is preferable that the concealing member is positioned in a thickness direction orthogonal to the first direction by the engagement between the engaging portion and the engaged portion. In this case, the concealing member is positioned even in the thickness direction.

  It is preferable that the panel main body or the concealing member is provided with guide means for positioning the concealing member in the thickness direction while allowing the concealing member to move in the first direction. In this case, the concealing member is easily positioned in the thickness direction.

  Preferably, the panel body is an instrument panel, the optional device is a head-up display projection device, and the concealing member is a bezel. In this case, the bezel can be provided at an appropriate position on the instrument panel of the vehicle, and the user can suitably use the head-up display system.

  Advantageous Effects of Invention According to the panel structure of the present invention, it is possible to provide a concealing member at an appropriate position even when the opening is deviated from a set position due to formation by post-processing, while realizing a low manufacturing cost.

  As shown in FIGS. 8 and 9, the bezel 5 has a tubular portion 51 having a tubular shape inserted into the opening 3a. As shown in FIGS. 3, 6 and 8, a first eave portion 52 protruding forward in a plate shape is formed at a front upper end of the cylindrical portion 51. As shown in FIGS. 4, 7 and 8, a second eave portion 53 projecting rearward in a plate shape is formed at the rear upper end of the cylindrical portion 51. As shown in FIG. 9, a third eave portion 54 projecting rightward in a plate shape is formed at the upper right end of the cylindrical portion 51, and a plate-shaped leftward is formed at the upper left end of the cylindrical portion 51. A projecting fourth eave portion 55 is formed. The first eaves 52 have a longer projecting length than the second eaves 53, the third eaves 54, and the fourth eaves 55. The length from the front end of the first eave portion 52 to the rear end of the second eave portion 53 is set longer than the length of the opening 3a in the front-rear direction. Similarly, the length from the right end of the third eave portion 54 to the left end of the fourth eave portion 55 is set longer than the length of the opening 3a in the left-right direction.

  As shown in FIGS. 3, 6 and 8, the bezel 5 has a first claw portion 56 projecting forward in a plate shape below the first eave portion 52. The first eave portion 52 and the first claw portion 56 extend substantially in parallel. The storage space 5 a is formed between the first eave portion 52 and the first claw portion 56 in the bezel 5. The storage space 5a can store the front edge of the opening 3a of the instrument panel 3.

  The bezel 5 has two fixed pieces 57 that protrude rearward below the second eaves 53 as shown in FIGS. 4, 7, and 8. The fixed pieces 57 are integrally formed with the support portion 59 extending in a columnar shape from the cylindrical portion 51, the shaft portion 61 formed in a cylindrical shape having a smaller diameter than the support portion 59, and the shaft portion 61. And the engaged portion 63. The support portion 59, the shaft portion 61 and the engaged portion 63 extend rearward coaxially. The rear end of the engaged portion 63 extends so as to be located rearward of the rear end of the second eave portion 53.

  The shaft portion 61 is aligned with the upper half cylindrical surface 36a of the engagement hole 36 in the engagement portion 35. The engaged portion 63 includes a plurality of branch portions 63a bent in the middle, and a space is formed between the respective branch portions 63a. The rear of the opening 3a of the instrument panel 3 is located between the second eave portion 53 and the fixed piece 57 in the bezel 5.
