[0016] The following will make the technical solutions and other beneficial effects of the present utility model obvious through a detailed description of the specific embodiments of the present utility model in conjunction with the drawings. In the drawings,

[0017] Figure 1 is a three-dimensional schematic diagram of a conventional portable computer;

[0018] Figure 2 is a top view of the upper cover of the main body of a conventional portable computer;

[0019] Figure 3 isFigure 2 Partial sectional view in the A-A direction;

[0020] Figure 4 It is a top cover of a conventional portable computer host and its partial schematic diagram;

[0021] Figure 5 and Figure 6 It is a partial sectional view of the top cover of the host of a preferred embodiment of the portable computer of the present invention;

[0022] Figure 7 It is a partial schematic diagram of the top cover of the host of a preferred embodiment of the portable computer of the present invention. Specific implementation mode

[0023] See Figure 5 、 Figure 6 and Figure 7 , Figure 5 、 Figure 6 It is a partial sectional view of the top cover of the host of a preferred embodiment of the portable computer of the present invention, and is supplemented with fingers to show the use state. A keyboard is assembled on the top cover; Figure 7 This is a partial schematic diagram of the top cover of the host of this preferred embodiment. The portable computer of the present invention includes a host and a keyboard provided on the top cover of the host, as well as the conventional designs of other portable computers. The keyboard of the portable computer of the present invention includes: a bottom plate 41, a metal keyboard frame 420, keycaps 43, and a support member 44; the metal keyboard frame 420 is integrally connected to the top cover of the host, and a plurality of key holes are provided on the metal keyboard frame 420 to expose the keycaps 43; corresponding to the key holes on the metal keyboard frame 420, the keycaps 43 are provided on the bottom plate 41 below via the support member 44; the edge of the key hole of the metal keyboard frame 420 corresponding to the lower edge of the text direction on the keycap 43 is a slope surface 421. Compared with Figure 4 it can be seen that on the basis of the structural design of the conventional portable computer, an additional inverted C-corner process is added to the lower edge of the metal keyboard frame 420, so that the original vertical metal sharp edge becomes a slope surface 421 with a gentle slope transition. In the pressed state, even if the top of the keycap 43 is lower than the metal keyboard frame 420, the slope surface 421 can prevent pinching the hand.

[0024] In this preferred embodiment, the slope surface 421 can be made by an inverted C-corner process, and the design and manufacturing costs are almost unchanged.

[0025] In this preferred embodiment, the keyboard of the portable computer further includes a plastic keyboard frame 45, which is fixed between the metal keyboard frame 420 and the bottom plate 41, thereby fixing the two together. The metal keyboard frame 420 can be fixed on the plastic keyboard frame 45 via a bonding glue layer. The bottom plate 41 is a metal bottom plate, and through holes are provided on the metal bottom plate. The plastic keyboard frame 45 can be fixed to the bottom plate 41 via a plastic hot melt head 46 passing through the through holes.

[0026] In this preferred embodiment, the thickness of the bonding glue layer can specifically be 0.1 mm, the thickness of the keycap 43 is 1.2 mm, the thickness of the plastic keyboard frame 45 is 0.8 mm, the thickness of the metal keyboard frame 420 is 0.8 mm, and the stroke of the keycap 43 is 1.5 mm, which is beneficial to realizing the design of the whole portable computer being thin and light, and is beautiful, durable.

[0027] In summary, the portable computer of the present utility model is beautiful and durable. When the user strikes the keyboard, the keyboard frame will not dig into the hand, improving the use comfort.

[0028] As described above, for those of ordinary skill in the art, various corresponding changes and deformations can be made according to the technical solution and technical concept of the present utility model, and all these changes and deformations should fall within the protection scope of the appended claims of the present utility model.
