High strength frame structure
A high strength frame structure of a portable computer is disclosed, comprising a main structure frame including at least an “L” shaped column, a bracket disposed on the “L” shaped column and used for supporting a touchpad and a keyboard, a metal foil bonded onto the bracket and a lower cover frame served as a base for supporting the main structure frame, wherein the “L” shaped column has a cylinder bump disposed thereon at a rear end, the cylinder bump being fastened to a fastener hole by means of a bolt or a hinge so that a mainframe and a display panel of the portable computer may be connected together, and the metal foil being bonded in a replaceable manner, having capability of electromagnetic interference (EMI) isolation and saving a later electroplating process. The high strength frame structure may be manufactured in a simple form and strength of upper and lower covers of the frame structure may be enhanced.

1. Field of the Invention
The present invention relates to a high strength frame structure and particularly to a high strength frame structure of a portable computer having a particular form made of materials of high strength.
2. Descriptions of the Related Art
With the rapid development of information technology, various digital electronic products have been born continually, such as portable computers, personal digital assistants (PDAs), flash drives and electronic books. Such digital electronic products have become important aids for human's work and life. Among them, the portable computers can be the most important since they possess the best operation processing capability and the largest storage space. Therefore, more attention are deserved to be paid to appearance of the portable computers so that consumers on the market may be appealed more.
Although the portable computers have been greatly improved in volume and weight, from being clumsy and large at early time to featuring miniature and compactness today, frame strength of the portable computers is relatively less paid attention. For the recently, there are some technologies associated with vibration and pressure-resistant designs for the portable computer frames set forth continually. Generally, the frames of the portable computers are formed by rigid plastic or compound materials and an upper cover and a lower cover thereof are coated with lacquer or protection materials for isolation of electromagnetic interferences (EMIs). Therefore, these frames have been improved particularly in high structure strength and EMIs prevention capability.
In seeking a better frame strength, metal or plastic materials are generally adopted as the material for the main structure of the portable computer. Referring to
Although the high rigid titanium alloy is provided circumferentially with respect to the base, only edges of the portable computer may be protected from damage and destruction and a keyboard and a touchpad therein may not be efficiently protected. In addition, since the fasteners are provided circumferentially with respect to the portable computer, damage on the central portion of the portable computer brought by the external may not be protected. In addition, the generally used rigid and strong materials often do not contribute to improved frame structure designs for stress elimination.
In view of this, the present invention provides an enhanced portable computer frame structure through which various internal and external stresses at peripheral and central positions may be resisted. Since such frame structure is provided with a main structure having a firmer base, the shortcomings as mentioned above may be well overcome.
SUMMARY OF THE INVENTIONIt is, therefore, an object of the present invention to provide a high strength frame structure through which a portable computer may be simplified in structure, cover strength of a main structure thereof may be enhanced and manufacturing process and cost therefor may be reduced.
To achieve the above object, the high strength frame structure of a portable computer comprises a main structure frame comprising at least an “L” shaped column, a bracket disposed on the “L” shaped column and used for supporting a touchpad and a keyboard thereon, a metal foil bonded onto the bracket and a lower cover served as a base for supporting the main structure frame, wherein the “L” shaped column has a cylinder bump disposed thereon at a rear end, the cylinder bump being fastened to a fastener hole by means of a bolt or a hinge so that a mainframe and a display panel of the portable computer may be connected together, and the metal foil being bonded in a replaceable manner and having capability of electromagnetic interferences (EMIs) isolation.
According to the present invention, the high strength frame structure is formed through an improved frame design created. Further, the frame structure is manufactured in an integral form so that a simplified frame design and an enhanced main structure may be achieved. In addition, the replaceable disposed metal foil may provide isolation of EMIs.
To enable the above and other objects, features and advantages to be more apparent to those skilled in the art, the present invention will be described in more detail taken from the preferred embodiments in conjunction with the accompanying drawings.
