Description

FIELD OF THE INVENTION

The present invention relates to enclosures with fixing structure, and more particularly, to an enclosure with fixing structure, for being applied to an electronic device.

BACKGROUND OF THE INVENTION

With the development of science and technology, portable or handheld electronic devices such as notebook computers, MP3, mobile disks, mobile phones, PDAs etc., which are much lighter thinner shorter and smaller, have multiple functions and are easy to use, are becoming more and more popular.

However, as the size of an electronic device shrinks, available spaces for each component of the electronic device are limited. As a result, the prior art technique that uses a metal enclosure fixing structure composed of screws or the like to fix each component has some defects: firstly, because of the limited spaces, in some certain circumstances, such a metal enclosure fixing structure can not be used; secondly, such a metal enclosure fixing structure can not prevent short circuits from happening; thirdly, such a metal enclosure fixing structure often abrades the components, especially those formed of plastic materials or the like; finally, such a metal enclosure is not easy to assemble and disassemble.

According to these defects, an improved fixing structure to fix components by hooks and grooves is proposed. Referring to FIG. 7, an enclosure fixing structure to fix an enclosure of a notebook computer is shown. The enclosure includes a switch cover 70 and an upper case member 72.

Therein, a plurality of hook portions 700 are disposed on the switch cover 70, a plurality of groove portions 720 corresponding to the hook portions 700 are disposed on the upper case member 72. Each of the groove portions 720 has a receiving space having the same length as that of the hook portions 700. To assemble the switch cover 70 and the upper case member 72, first, the switch cover 70 is positioned, that is, the hook portions 700 are aligned with the corresponding groove portions 720, then, the hook portions 700 are inserted in the groove portions by a vertical force to fix the switch cover 70 to the upper case member 72.

While inserting the hook portions 700 to the groove portions by the vertical force, because the upper case member 72 formed of metal such as Mg alloy is not easy to be deformed to provide enough spaces to the hook portions 700, a large vertical forces is needed to counteract the high resistance force coming from the upper case member 72, which often results in permanent deformation and even damage of the hook portions 700 and accordingly results in failure of fixing. Further, material fatigue is easy to occur to a part of the hook portions 700 where the stress focuses when the enclosure fixing structure is assembled and disassembled several times.

Accordingly, there is a need to develop an enclosure fixing structure which is easy to assemble and disassemble and has a good fixing effect.

SUMMARY OF THE INVENTION

According to the above defects, a primary objective of the present invention is to provide an enclosure with fixing structure, which is easy to be assembled and disassembled, for an electronic device.

Another objective of the present invention is to provide an enclosure with fixing structure, which is not easy to be damaged during assembling and disassembling, for an electronic device.

A further objective of the present invention is to provide an enclosure with fixing structure, which has a stable and reliable fixing effect, for an electronic device.

To achieve the above and other objectives, an enclosure with fixing structure according to the present invention comprises: a cover member having a plurality of hook portions; and a case member having a plurality of groove portions, wherein each of the groove portions further comprises a receiving space and a stop portion, such that when a horizontal force is exerted (being the same as the direction of Arrow X of FIG. 1), the hook portions subsequently deposed in the receiving spaces are coupled to the stop portions, for fixing the cover member to the case member.

Preferably, the hook portions are wedge-shaped hooks or right-angle hooks. Each of the hook portions may be formed facing an edge of the cover member, formed with its backside facing an edge of the cover member, or formed in a direction the horizontal force exerted. Further, each of the hook portions may have a wedge-shaped side, which allows the hook portions to be easily guided and coupled to the stop portions in a horizontal direction.

Preferably, the stop portions of the groove portions are formed corresponding to the hook portions such that the stop portions may be coupled with the corresponding hook portions. In addition, each of the stop portions has a wedge-shaped opening, which allows the hook portions to be easily guided and coupled to the stop portions in a horizontal direction.

To fix the cover member to the case member, the hook portions of the cover member is first deposed in the receiving spaces for positioning, then the hook portions are guided and coupled to the stop portions, when exerting an horizontal force.

Compared with the prior art, the enclosure with fixing structure of the present invention effectively reduces the resistance force while inserting the hook portions into the groove portions, thus it is easy to be assembled and disassembled without strain. Moreover, the present invention is capable of provide a stable and reliable effect without damaging the structure.
