Abstract
A chassis member is used for an electronic device, including a face plate, and a frame to be fixed to one face of the face plate and provided along at least one side of a peripheral edge of the one face. The frame is formed by laminating a plurality of layers of a prepreg containing reinforced fiber impregnated with resin. The frame has a frame body to be fixed to the one face, and a shaft supporting portion formed integrally with the frame body and formed with an insertion hole for press-fitting a shaft-like member.
Claims5
A chassis member used for an electronic device, comprising:
- a face plate in the form of a sheet;
- and a frame that is fixed to one face of the face plate and that is along at least one side of a peripheral edge of the one face, wherein the frame has a plurality of laminated layers of a prepreg containing reinforced fiber impregnated with resin, wherein the frame has:
- a frame body fixed to the one face;
- and a shaft supporting portion integral with the frame body and has an insertion hole for press-fitting a shaft-like member;
- and
- wherein the shaft supporting portion has a projecting portion extending from the one side in a surface normal direction of the one face, and the insertion hole is in the projecting portion along the frame body and is opened on an end face of the projecting portion and in a direction that crosses the surface normal direction;
- and
- wherein the projecting portion has a boss section surrounding at least a part of a periphery of the insertion hole, and the chassis member further comprises a reinforcing ring surrounding an outer peripheral surface of the boss section;
- and
- wherein the reinforced fiber extends along at least a longitudinal direction of the one side.
An electronic device comprising a chassis having a chassis member, wherein the chassis member comprises:
- a face plate in the form of a sheet;
- and a frame that is fixed to one face of the face plate and that is along at least one side of a peripheral edge of the one face, wherein the frame has a plurality of laminated layers of a prepreg containing reinforced fiber impregnated with resin, wherein the frame has:
- a frame body fixed to the one face;
- and a shaft supporting portion integral with the frame body and has an insertion hole for press-fitting a hinge shaft, wherein the electronic device further comprises:
- a hinge relatively fixed to the chassis by the hinge shaft press-fitted into the insertion hole;
- and a second chassis relatively rotatably coupled to the chassis by the hinge shaft about its axis;
- and
- wherein the shaft supporting portion has a projecting portion extending from the one side in a surface normal direction of the one face, and the insertion hole is in the projecting portion along the frame body and is opened on an end face of the projecting portion and in a direction that crosses the surface normal direction;
- and
- wherein the projecting portion has a boss section surrounding at least a part of a periphery of the insertion hole, and the chassis member further comprises a reinforcing ring surrounding an outer peripheral surface of the boss section;
- and
- and wherein the reinforced fiber extends along at least a longitudinal direction of the one side.
