Abstract

A housing includes: a top cover; a bottom cover having a rising wall member erected toward the top cover and joined to the top cover at a rim; and a reinforcing structure which is disposed in a space divided by the top cover and the bottom cover, and has an opening, the reinforcing structure being joined to the bottom cover. The bottom cover is formed of a material having a thickness of 0.1 mm or more and 0.8 mm or less and an elastic modulus of 20 GPa or more and 120 GPa or less.

First claim

The invention claimed is:

1. A housing comprising: a top cover; a bottom cover having a flat portion and a rising wall member erected from a rim of the flat portion toward the top cover and joined to the top cover; and a reinforcing structure which is disposed in a space divided by the top cover and the bottom cover,
wherein the bottom cover is formed of a material having a thickness of 0.1 mm or more and 0.8 mm or less and an elastic modulus of 20 GPa or more and 120 GPa or less,
wherein the reinforcing structure includes:
a flat portion or a curved portion; and
a rising wall member erected on a rim of the flat portion or on a rim of the curved portion, and

wherein the reinforcing structure is joined to the bottom cover with a hollow structure formed between the flat portion or the curved portion of the reinforcing structure and the flat portion of the bottom cover.

2. The housing according to claim 1 ,
wherein the reinforcing structure is formed of a material having a thickness of 0.3 mm or more and 0.8 mm or less, and an elastic modulus of 20 GPa or more and 120 GPa or less.

3. The housing according to claim 1 ,
wherein the reinforcing structure, and the top cover or the bottom cover to which the reinforcing structure is joined are formed of a fiber-reinforced composite material that is a cured product of a laminate of prepregs including a reinforcing fiber and a matrix resin.

4. The housing according to claim 1 ,
wherein the reinforcing structure is joined to the bottom cover by thermal welding.

5. The housing according to claim 1 ,
wherein the reinforcing structure is joined to the bottom cover in such a manner that the peeling load at 23° C. is within a range of 60 N/cm 2 or more and 5000 N/cm 2 or less, and the peeling load at 200° C. is within a range of less than 60 N/cm 2 .

6. The housing according to claim 1 ,
wherein the reinforcing structure is joined directly to the bottom cover.

7. The housing according to claim 1 ,
wherein the projected area of the reinforcing structure in a direction of the bottom cover which is joined to the reinforcing structure is within a range of 60% or more and 95% or less of the area of the bottom cover to which the reinforcing structure is joined.

8. The housing according to claim 1 ,
wherein the volume of a hollow structure formed by joining the reinforcing structure to the bottom cover is within a range of 55% or more and 95% or less of the volume of the space.

9. The housing according to claim 1 ,
wherein a heat generation member is disposed on a surface of the reinforcing structure on the hollow structure side.

10. The housing according to claim 1 ,
wherein another reinforcing structure connecting the inner surface of the reinforcing structure and the bottom cover to which the reinforcing structure is joined is provided in a hollow structure formed between the reinforcing structure and the bottom cover to which the reinforcing structure is joined.

11. A housing comprising: a top cover; a bottom cover having a flat portion and a rising wall member erected from a rim of the flat portion toward the top cover and joined to the top cover at a rim; and a reinforcing structure which is disposed in a space divided by the top cover and the bottom cover,
wherein the bottom cover is formed of a fiber-reinforced composite material that is a cured product of a laminate of prepregs including a reinforcing fiber and a matrix resin,
wherein the reinforcing structure includes:
a flat portion or a curved portion; and
a rising wall member erected on a rim of the flat portion or on a rim of the curved portion, and

wherein the reinforcing structure is joined to the bottom cover with a hollow structure formed between the flat portion or the curved portion of the reinforcing structure and the flat portion of the bottom cover.

12. A housing comprising: a top cover; a bottom cover having a flat portion and a rising wall member erected from a rim of the flat portion toward the top cover and joined to the top cover at a rim; and a reinforcing structure which is disposed in a space divided by the top cover and the bottom cover,
wherein the reinforcing structure is formed of a material having a thickness of 0.3 mm or more and 0.8 mm or less and an elastic modulus of 20 GPa or more and 120 GPa or less,
wherein the reinforcing structure includes:
a flat portion or a curved portion; and
a rising wall member erected on a rim of the flat portion or on a rim of the curved portion, and

wherein the reinforcing structure is joined to the bottom cover with a hollow structure formed between the flat portion or the curved portion of the reinforcing structure and the flat portion of the bottom cover.

13. The housing according to claim 12 ,
wherein the bottom cover is formed of a material having a thickness of 0.1 mm or more and 0.8 mm or less, and an elastic modulus of 20 GPa or more and 120 GPa or less.

14. A housing comprising: a top cover; a bottom cover having a flat portion and a rising wall member erected from a rim of the flat portion toward the top cover and joined to the top cover at a rim; and a reinforcing structure which is disposed in a space divided by the top cover and the bottom cover,
wherein the reinforcing structure is formed of a fiber-reinforced composite material that is a cured product of a laminate of prepregs including a reinforcing fiber and a matrix resin,
wherein the reinforcing structure includes:
a flat portion or a curved portion; and
a rising wall member erected on a rim of the flat portion or on a rim of the curved portion, and

wherein the reinforcing structure is joined to the bottom cover with a hollow structure formed between the flat portion or the curved portion of the reinforcing structure and the flat portion of the bottom cover.

15. A housing comprising: a top cover; a bottom cover having a flat portion and a rising wall member erected from a rim of the flat portion toward the top cover and joined to the top cover at a rim; and a reinforcing structure which is disposed in a space divided by the top cover and the bottom cover,
wherein the reinforcing structure includes:
a flat portion or a curved portion; and
a rising wall member erected on a rim of the flat portion or on a rim of the curved portion,

wherein the reinforcing structure is joined to the bottom cover or the top cover with a hollow structure formed between the reinforcing structure and the bottom cover or the top cover, and
wherein a ratio of the linear expansion coefficient of the reinforcing structure to the linear expansion coefficient of the bottom cover or the top cover which is joined to the reinforcing structure is within a range of 0.1 or more and 10 or less.
