Electronic apparatus and manufacturing method thereof
An electronic apparatus includes: a flat rectangular chassis that includes a side wall frame in which at least three side walls are formed by bending an extruded material, a first cover configured to form one surface of the chassis by being combined with the side wall frame, a second cover configured to form another surface of the chassis by being combined with the side wall frame, and a plate frame that has a plate shape and is provided between facing portions of the three side walls.
1 . An electronic apparatus comprising:
a flat rectangular chassis that includes
a side wall frame in which at least three side walls are formed by bending an extruded material,
a first cover configured to form one surface of the chassis by being combined with the side wall frame,
a second cover configured to form another surface of the chassis by being combined with the side wall frame, and
a plate frame that has a plate shape and is provided between facing portions of the three side walls.
2 . The electronic apparatus according to claim 1 , wherein
the plate frame includes two partition walls having an angle intersecting with a plate-shaped surface.
3 . The electronic apparatus according to claim 2 , wherein
a main board including a main control unit is provided in the chassis, and
at least the main control unit of the main board is provided in a space surrounded on three sides by the plate-shaped surface and the two partition walls in the plate frame.
4 . The electronic apparatus according to claim 2 , wherein
the plate frame has a flat U-shape by the plate-shaped surface and the two partition walls.
5 . The electronic apparatus according to claim 1 , wherein
the plate frame is an extruded material.
6 . The electronic apparatus according to claim 1 , wherein
the chassis is at least one of a first chassis and a second chassis that are connected to be relatively pivotable by a hinge,
the side wall frame has a quadrangular C-shape having four bent portions, and
the plate frame is connected to close an opening portion of the quadrangular C-shape of the side wall frame near the opening portion.
7 . The electronic apparatus according to claim 6 , wherein
the plate frame is fixed to a side wall that forms both end portions of the opening portion in the side wall frame.
8 . The electronic apparatus according to claim 1 , wherein
the chassis is at least one of a first chassis and a second chassis that are connected to be relatively pivotable by a hinge, and
the side wall frame has a quadrangular C-shape having four bent portions, and the hinge is disposed in an opening portion of the quadrangular C-shape.
9 . The electronic apparatus according to claim 1 , wherein
the side wall frame includes an inward projecting portion, and
the plate frame includes an outward projecting portion configured to be fixed to the inward projecting portion.
10 . A manufacturing method of an electronic apparatus including a flat rectangular chassis, the manufacturing method comprising:
obtaining a side wall frame by bending an extruded material to form at least three side walls;
attaching a plate frame having a plate shape across facing portions of the three side walls; and
attaching a first cover to one side of the side wall frame and attaching a second cover to the other side of the side wall frame.
