Description

laptop

The present invention relates to a notebook computer, in particular to a notebook computer that can drive a support member to protrude or retract from the base by the rotation of the display.

At present, notebook computers have been widely used in people's daily life. Under the current trend of high-performance notebook computers becoming thinner and lighter, it is difficult to take care of good heat dissipation. Therefore, some notebook computers use a lifting mechanism to lift the base to improve heat dissipation. However, the existing lifting mechanism is relatively complicated, and the relative research and development costs are relatively high. In addition, the lifting mechanism is too bulky, occupying too much internal space of the notebook computer, thereby compressing the installation space of other hardware. Furthermore, in order to meet the requirements of heat dissipation regulations, the bottom of the base and the desktop must reach a certain height, resulting in the rear foot pad being too high. Even though the body design is thin, the desktop looks thick. What's more, in order to meet the heat dissipation requirements of the existing high-performance notebook computers, many heat dissipation holes need to be added to the appearance, which makes the appearance not clean and simple.

The present invention provides a notebook computer that can drive the supporting part to protrude or retract from the base by the rotation of the display, so as to solve the above-mentioned problems.

According to an embodiment, the notebook computer of the present invention includes a base, a display, a shaft structure, a linking part, a supporting part and a transmission part. The hinge structure pivotally connects the monitor to the base. The linkage part is arranged on the rotating shaft structure. The supporting member is movably arranged on the base. The transmission part is connected with the linkage part and the supporting part. When the display rotates relative to the base to unfold or collapse, the rotating shaft structure drives the linkage to rotate, and the linkage drives the support to move through the transmission, so that the support protrudes or retracts from the base.

In summary, the present invention utilizes the linking parts on the rotating shaft structure and The transmission part drives the supporting part to protrude or retract the base, so that the base can be raised or lowered. When the display rotates relative to the base and unfolds, the interlocking part and the transmission part on the rotating shaft structure will drive the supporting part to protrude from the base to lift the base. At this time, there is enough space under the base to allow a large amount of cold air to enter from the bottom to improve the heat dissipation effect. Since the base is raised to meet the bottom air intake height required by the heat dissipation specification, it can replace the thick foot pad at the bottom of the existing notebook computer, making the notebook computer have a thin, light and elegant appearance design. Lifting the base also raises the monitor for a more comfortable reading angle for the user. In the present invention, a lower cover can also be provided on the bottom of the base, and the heat dissipation module (for example, heat dissipation fins, vapor chambers, etc.) can be arranged in the base corresponding to the lower cover. When the supporting piece protrudes from the base, the supporting piece drives the lower cover to open relative to the base. At this time, the heat dissipation module will be exposed from the gap between the lower cover and the base, so as to improve the heat dissipation effect. In addition, the present invention can hide the heat dissipation holes in the lower cover. When the display is unfolded relative to the base, the lower cover opens to reveal the heat dissipation holes. The overall appearance of the small computer is more simple and beautiful. The assembly method of the hinge structure of the present invention is the same as that of the conventional notebook computer, so no additional assembly difficulties will be caused. In addition, the design of the rotating shaft structure, linkage, support and transmission parts of the present invention is simple, and the development time is fast, which can effectively reduce the research and development cost.

The advantages and spirit of the present invention can be further understood through the following detailed description of the invention and the accompanying drawings.
