Mobile personal computer and electronic device
View Patent ↗According to one embodiment, a mobile personal computer includes: a display panel with a display screen; a board assembly including a board and a component mounted on the board; and a housing including an outer housing constituting an outline and an inner housing arranged between the display panel and the board assembly, and houses the board assembly.
1. A mobile personal computer comprising:
a display panel comprising a display screen;
a board assembly comprising a board and a first component mounted on the board;
a housing configured to house the board assembly, comprising an outer housing forming an outline and an inner housing between the display panel and the board assembly;
a first protrusion provided on the outer housing and protruding toward a first portion of the board assembly;
a second protrusion provided on the inner housing and protruding toward the first portion of the board assembly, the second protrusion being positioned on an opposite side of the first protrusion with respect to the first portion of the board assembly;
a third protrusion on the outer housing and protruding toward a second portion of the board assembly, the second portion being positioned nearer to an edge of the board than the first portion; and
a displacement-controlling mechanism comprising a first fixing member and a second fixing member, the first fixing member being fixed to the board assembly and positioned between the first protrusion and the second protrusion, the first fixing member comprising a head portion and an end portion, the head portion of the first fixing member opposed to the second protrusion between the display panel and the board assembly, the end portion of the first fixing member being provided on the opposite side of the head portion of the first fixing member and being opposed to the first protrusion, the second fixing member being fixed to the board assembly and comprising a head portion, the head portion of the second fixing member being opposed to the third protrusion between the board assembly and the outer housing, the displacement-controlling mechanism being configured to control relative approach between the outer housing and the inner housing.
2. The mobile personal computer of claim 1 , wherein the first portion is positioned in a circuit-forming region inside a circumferential edge of the board assembly.
3. The mobile personal computer of claim 2 , wherein the first portion is positioned nearer to a center of gravity of the board than the second portion.
4. The mobile personal computer of claim 2 , wherein a second component to which the first fixing member is fixed is provided at the first portion on the board assembly.
5. The mobile personal computer of claim 1 , wherein the first portion is positioned closer to a center of gravity of the board than the second portion.
6. The mobile personal computer of claim 5 , wherein a second component to which the first fixing member is fixed is provided at the first portion on the board assembly.
7. The mobile personal computer of claim 1 , wherein a second component to which the first fixing member is fixed is provided at the first portion on the board assembly.
8. The mobile personal computer of claim 7 , wherein
a pressing member configured to press a heat pipe against the first component is fixed to the board by the first fixing member and the second component.
9. The mobile personal computer of claim 7 , wherein
when the outer housing is bent toward the inner housing, the first protrusion contacts the end portion of the first fixing member and the second protrusion contacts the head portion of the first fixing member.
10. An electronic device comprising:
a display panel comprising a display screen;
a board assembly comprising a board and a component mounted on the board;
a housing comprising an outer housing forming an outline and an inner housing between the display panel and the board assembly, the housing being configured to house the board assembly;
a first protrusion provided on the outer housing and protruding toward a first portion of the board assembly;
a second protrusion provided on the inner housing and protruding toward the first portion of the board assembly, the second protrusion being positioned on an opposite side of the first protrusion with respect to the first portion of the board assembly;
a third protrusion on the outer housing and protruding toward a second portion of the board assembly, the second portion being positioned nearer to an edge of the board than the first portion; and
a displacement-controlling mechanism comprising a first fixing member and a second fixing member, the first fixing member being fixed to the board assembly and positioned between the first protrusion and the second protrusion, the first fixing member comprising a head portion and an end portion, the head portion of the first fixing member being opposed to the second protrusion between the display panel and the board assembly, the end portion of the first fixing member being provided on the opposite side of the head portion of the first fixing member and opposed to the first protrusion, the second fixing member being fixed to the board assembly and comprising a head portion, the head portion of the second fixing member being opposed to the third protrusion between the board assembly and the outer housing, the displacement-controlling mechanism being configured to control relative approach between the outer housing and the inner housing.
11. The electronic device of claim 10 , wherein when the outer housing is bent toward the inner housing, the first protrusion contacts the end portion of the first fixing member and the second protrusion contacts the head portion of the first fixing member.
