Description

Notebook computer

The invention relates to a notebook computer, in particular to a notebook computer with a keyhole and a vent hole.

Most notebook computers have a keyboard for the user to operate. Please refer to FIG. 1 and FIG. 2, FIG. 1 is a perspective view of a conventional notebook computer 1, and FIG. 2 is an enlarged view of a portion A of FIG. The design of the keyboard 20 is such that a plurality of keycap holes 11 are disposed on the casing 10 of the notebook computer 1, and the key caps 21 of the keyboard 20 are respectively pierced by the keyholes 11, so that the notebook computer 1 can be simplified. The beauty. In addition, since the keycap 21 only protrudes slightly from the casing 10, and the keycaps 21 are separated by the casing 10, when foreign matter or dust falls to the keyboard area Z1 on the casing 10, the user can easily Foreign matter or dust is removed for easy cleaning by the user.

In order to make the keyboard 20 more aesthetically pleasing and to prevent small foreign matter from falling into the casing 10, in general, the gap between the keycap 21 and the keycap hole 11 is reduced as much as possible. However, too small a gap creates a problem of heat dissipation, and air cannot effectively enter the inside of the casing 10 via the gap. The conventional solution is to increase the width of the gap. However, this method is contrary to the foregoing, which makes the keyboard 20 more beautiful and prevents fine foreign matter from falling into the casing 10.

In order to solve the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a notebook computer having a keyhole of a keyboard having a vent hole, so that the air outside the notebook computer can enter the outside of the notebook through the vent hole of the keycap. .

In order to achieve the above object, the present invention provides a notebook computer comprising a casing and a plurality of keycaps. The housing is provided with a plurality of keycap holes. The key caps are respectively located in the keycap holes and respectively have a first ventilation hole and a second ventilation hole. The first vent hole is located outside the casing, the second vent hole is located inside the casing, and the first vent hole and the second vent hole communicate with each other.

In order to achieve the above object, the present invention further provides a notebook computer comprising a casing and a plurality of keycaps. The housing is provided with a plurality of keycap holes. The key caps are respectively disposed on the keycap holes, and each has a vent hole, wherein the vent hole extends from the outside of the casing to the inside of the casing.

In summary, since the notebook computer of the present invention has a vent hole, the air outside the casing can enter the inside of the casing through the vent hole, thereby enhancing the heat dissipation efficiency of the notebook computer.

Please refer to FIG. 3 to FIG. 6 , FIG. 3 is a perspective view of a first embodiment of the notebook computer 2 of the present invention, FIG. 4 is an enlarged view of a portion B of FIG. 3 , and FIG. A schematic view of a first embodiment of a keycap 51, and FIG. 6 is a cross-sectional view of a first embodiment of the notebook computer 2 of the present invention.

The notebook computer 2 includes a host 30, a display screen 40, and a keyboard 50. The main unit 30 includes a casing 31 and a main board 32. The casing 31 can be a hollow structure, the casing 31 is provided with a keyboard area Z1, and a plurality of keycap holes 311 are disposed on the keyboard area Z1. The motherboard 32 is disposed inside the casing 31, and the motherboard 32 may include components such as a central processing unit (not shown). The display screen 40 can be pivoted to the host 30 or separated from the host 30.

The keyboard 50 includes a plurality of keycaps 51, a plurality of support units 52, and a button substrate 53. The key cap 51 is disposed on the button substrate 53 via the support unit 52. The button substrate 53 is disposed inside the casing 31 and is provided with a plurality of through holes 531. The key caps 51 are respectively located in the keyhole holes 311 of the casing 31, and a gap S1 can be formed between the keycaps 51 and the keyholes 311. The keyboard 50 described above may be a keyboard such as a membrane keyboard, a mechanical keyboard or a capacitive keyboard. Since other detailed structures of the keyboard 50 are not the focus of this embodiment, they are omitted.

The keycap 51 has a pressing surface 511, a plurality of side surfaces 512 and a supporting surface 513. The pressing surface 511 is located outside the casing 31 and outside the keyhole 311 and is pressable by a user. The side surface 512 is adjacent to the periphery of the pressing surface 511 and extends outside the casing 31 to the inside of the casing 31, that is, the side surface 512 can penetrate and exceed the keyhole 311. The support surface 513 is opposite to the pressing surface 511 and is adjacent to the side surface 512. The support surface 513 is located inside the casing 31 and is located outside the keycap hole 311.

The key cap 51 can be a hollow shell structure, and an air flow space S2 is formed inside the key cap 51. The key cap 51 has a plurality of first vent holes h1 and a second vent hole h2. The first vent hole h1 is disposed on the side surface 512, and the second vent hole h2 is disposed on the support surface 513. The first vent hole h1, the second vent hole h2, and the airflow space S2 communicate with each other. As can be seen from FIGS. 4 and 6, the first vent hole h1 is located outside the casing 31 and the keyhole 311, and the second vent hole h2 is located inside the casing 31.

Referring to FIG. 6, an air flow passage C1 is formed between the main board 32 and the key substrate 53, and the first ventilation hole h1, the second ventilation hole h2, the through hole 531, and the air flow passage C1 communicate with each other. Generally, a fan (not shown) is provided inside the notebook computer 2 to extract heat inside the casing 31 through the air flow passage C1. In this embodiment, the air outside the casing 31 can enter the inside of the casing 31 along an air flow path F1. For example, air may enter the airflow space S2 via the first vent hole h1. Thereafter, after the air flows out of the airflow space S2 via the second vent hole h2, the air can pass through the through hole 531 and enter the air flow passage C1. Through the first vent hole h1 and the second vent hole h2 widely distributed on the host 30 of the embodiment, the resistance of the air outside the casing 31 to the airflow space S2 can be reduced to increase the heat dissipation efficiency of the host 30.

In addition, in the present embodiment, air can directly flow into the inside of the casing 31 directly through the gap S1. When the aforementioned fan is stopped, air may flow from the air flow passage C1 to the outside of the casing 31 in the opposite direction of the air flow path F1. Further, in order to further reduce the resistance of the air passing through the through holes 531, the through holes 532 may be provided on the key substrate 53 between the two adjacent key caps 51.

In summary, in the embodiment, the gap S1 between the key cap 51 and the keyhole 311 can be reduced as much as possible without hindering the pressing of the keycap 51, and the air outside the casing 31 can pass through the first pass. The air hole h1 and the second air vent h2 enter the inside of the casing 31 and do not hinder the heat dissipation of the notebook computer 2.

Please refer to FIG. 7 for a cross-sectional view of a second embodiment of the notebook computer of the present invention. The main difference from the first embodiment is that the length of the first vent hole h1a of the key cap 51a is long, that is, the length of the first vent hole h1a is greater than the length of the key cap hole 311, and the first vent hole h1a is exposed. The inside and the outside of the casing 31. The support unit 52a is provided with a central portion of the support surface 513a, and the second vent hole h2a is disposed at the edge of the support surface 513a. In another embodiment, the air outside the casing 31 can enter the key cap 51 via the first vent hole h1a located outside the casing 31, and enter the casing 31 via the first vent hole h1a located inside the casing 31. Internally, the keycap 51a can be selected to not provide the second vent hole h2a.

As shown in Fig. 7, air can pass from the air flow passage C1, the perforations 531, 532 to the first vent hole h1a and the second vent hole h2a via an air flow path F2. Finally, air flows to the outside of the casing 31 via the first vent hole h1a. Air may also flow into the airflow passage C1 in the opposite direction of the airflow path F2.
