First Embodiment FIG. 1 is a perspective view of a framed panel 100 according to a first embodiment of the present invention. The panel with frame 100 is formed by joining a frame 101 serving as an outer frame surrounding the panel mounting area and a panel 102 arranged in the frame 101 so as to cover the panel mounting area. It is assumed that the framed panel 100 is arranged in a three-dimensional space (XYZ coordinate space) as shown in FIG.

  FIG. 2 is a sectional view taken along the line P-P 'in FIG. As shown in FIG. 2, an assembly joint 110 between the frame 101 and the panel 102 includes a seal member 103 that joins the frame 101 and the panel 102, and a groove rubber 104.

  The frame 101 includes a frame portion 101a forming an outer frame of the housing, and a mounting piece 101b extending from a center or substantially a center of a side surface of the frame portion 101a in a mounting direction of the panel 102. The attachment piece 101b is not limited to a structure extending from the center or substantially the center of the side surface of the frame 101a, but has a structure extending from an arbitrary position on the side surface of the frame 101a.

  The panel 102 is arranged in the frame 101 so as to cover the panel mounting area. Assuming that the upper surface of the panel 102 is the outer surface 102a, the lower surface is the inner surface 102b, and the surface connecting the periphery of the outer surface 102a and the periphery of the inner surface 102b is the peripheral surface, the panel 102 has a mounting piece 101b of the frame 101 at the peripheral surface. Joined to. Two panels 102 are arranged on the upper side and the lower side. In FIG. 2, for example, the Z direction is referred to as “up”, and the (−Z) direction is referred to as “down”.

  The peripheral surface of the panel 102 has a structure in which the outer surface 102a is cut in an inclined manner so that the outer surface 102a protrudes more outward than the inner surface 102b. The surface cut in an inclined shape is referred to as an inclined surface 102c.

  The lower panel 102 also has a structure similar to that of the upper panel 102, and the lower panel 102 is provided with the inclined surface 102c of each panel 102 so as to sandwich the edge of the mounting piece 101b on which the groove rubber 104 is mounted. A panel 102 is provided.

  The sealing material 103 is a material having elasticity after curing, and is applied so as to fill a space created between the inclined surface 102c of the panel 102, the mounting piece 101b, and the groove rubber 104. The groove rubber 104 is, for example, an elastic member having a U-shaped cross section, and is mounted so as to be in close contact with the edge of the mounting piece 101b.

  FIGS. 3A to 3E are diagrams illustrating an example of a joining procedure of the frame 101 and the panel 102 according to the first embodiment. With reference to FIG. 3, a joining procedure of the frame 101 and the panel 102 will be described.

  First, as shown in FIG. 3A, a groove rubber 104 is attached to the edge of the mounting piece 101b of the frame 101. Subsequently, as shown in FIG. 3B, the lower side, that is, the lower panel 102 of the two panels 102 shown in FIG. 2 is attached to the edge of the mounting piece 101b with the inclined surface 102c. It is arranged so as to be in contact with the grooved rubber 104.

  Subsequently, as shown in FIG. 3C, the upper panel 102 is tilted so that its inclined surface 102c faces the inclined surface 102c of the lower panel 102, that is, the inclined surfaces of the upper and lower panels 102. The mounting piece 102b is disposed so as to sandwich the edge of the mounting piece 101b on which the groove rubber 104 is mounted by 102c. At this time, the upper panel 102 and the lower panel 102 may be fixed with rivets or the like via holes (not shown) or bonded with an adhesive or the like.

  Then, as shown in FIGS. 3D and 3E, the sealing material is filled so as to fill the space created between the inclined surface 102c of the panel 102, the edge of the mounting piece 101b, and the groove rubber 104. 103 is applied. When the sealing material 103 is cured, the frame 101 and the panel 102 are joined. By the above procedure, the frame 101 and the panel 102 are joined.

  FIG. 4A is a diagram illustrating a structure in which a load is applied to the frame 101 and the panel 102 joined in the procedure shown in FIG. When a load is applied to the panel 102 in the direction indicated by the arrow in FIG. 4A, the panel 102 is deformed. Here, in FIG. 4A, the outer shapes of the panel 102 and the frame 101 before deformation are indicated by dotted lines.

  At this time, the mounting piece 101b of the frame 101 also deforms following the deformation of the panel 102. That is, when a load is applied to the panel 102 in the direction indicated by the arrow, the lower panel 102 pushes up the mounting piece 101b of the frame 101 as shown in FIG. As described above, in the assembled joint portion 110 according to the present embodiment, the frame 101 and the panel 102 are not firmly fixed by rivets or the like, but are joined by the elastic groove rubber 104 and the sealing material 103. Even if the panel 102 or the frame 101 is distorted, they can flexibly follow each other. Therefore, it is possible to prevent a large load from being applied in the direction in which the sealing material 103 is peeled off.

  FIG. 5 is a diagram showing a joint structure between a frame 101 provided with mounting pieces 101b in two directions perpendicular to each other from a frame 101a and a panel 102. Using the frame 101 and the panel 102 joined by the assembly joint 110 as shown in FIG. 5, a rectangular parallelepiped casing 200 as shown in FIG. 6, for example, can be assembled. FIG. 7 is a perspective sectional view taken along line Q-Q ′ in FIG.

  Although FIG. 5 shows the frame including the mounting pieces 101b extending in two directions perpendicular to each other from the frame 101a, the frame is not limited to this structure. That is, by adjusting the direction of the attachment piece 101b extending from the frame 101a, it is possible to assemble not only a rectangular parallelepiped but also various polyhedral casings having a high waterproof effect.

  As described above, according to the first embodiment, the groove rubber 104 is attached to the edge of the mounting piece 101b of the frame 101, and the panel 102 having the inclined surface 102c is used to mount the end of the mounting piece 101b from above and below. Insert the edge. Then, the frame 101 and the panel 102 are joined by applying the sealing material 103 so as to fill the gap between the inclined surface 102c, the groove rubber 104, and the mounting piece 101b.

  By employing the above configuration, according to the first embodiment, even when an applied load is applied to the panel 102 and the frame 101, the panel 102 and the frame 101 can follow each other. Accordingly, since breakage or peeling of the seal member 103 can be prevented, the effect of preventing the seal (waterproof) function between the panel 102 and the frame 101 from being impaired can be obtained.

  According to the first embodiment, the groove rubber 104 is attached to the edge of the mounting piece 101b of the frame 101, and the panel 102 and the frame 101 are joined with the sealing material 103 having elasticity after curing. . Accordingly, since the elastic member is interposed between the frame 101 and the panel 102, the vibration of the panel 102 can be reduced by the damping effect of the frame 101 and the panel 102 when the panel 102 resonates. As a result, according to the first embodiment, it is possible to reduce the noise and the like generated by the resonance of the panel 102.

  Panel 310 has a second surface (inner surface) facing the first surface (outer surface), and a peripheral surface connecting the periphery of the first surface and the periphery of the second surface. However, the first surface side has an inclination protruding outward from the second surface side.

  The frame 320 is disposed so as to surround the panel 310 and includes a mounting piece extending in a direction in which the panel 310 is mounted. The elastic member 330 is mounted on the edge of the mounting piece of the frame 320. The sealing material 340 is applied so as to fill a space between the peripheral surface of the panel 310 arranged to be in contact with the elastic member 330, the elastic member 330, and a mounting piece of the frame 320 to which the elastic member 330 is mounted. .

  The two panels 310 are arranged so as to sandwich the edge of the mounting piece of the frame 320 and the elastic member 330 between the respective peripheral surfaces.

  By adopting the above configuration, according to the second embodiment, even if an externally applied load is applied to the panel 310 and the frame 320, they can follow each other. The effect that generation can be prevented is obtained.
