Problems solved by technology

Usually, most of the notebook keyboards are plastic keycaps. Since the mechanical properties of plastic keycaps cannot be guaranteed in an extremely thin case, portable electronic devices such as notebooks using plastic keycaps cannot meet the needs of thinning and thinning. In addition, the single appearance and texture of plastic keycaps cannot meet the increasing requirements of users for product quality, so they cannot meet the needs of aesthetics

preparation example Construction

[0038]The preparation methods of the above three kinds of workpieces can all obtain the workpieces provided by the present invention. The mold used can be a mold with multiple cavities, which can be prepared at the same time, saving time and cost. Simultaneously, the mold is also coated with a release agent, so The release agent is preferably a silicone oil release agent or a fluorine release agent. But the workpiece is not limited to be prepared by using the above three methods. The above three methods are integrally formed of the surface layer and the fixing part, and no adhesive is used for bonding, so that the combination of the surface layer and the fixing part is more firm and not easy to fall off. At the same time, the integral molding method saves the thickness of the adhesive, making the prepared product lighter, thinner and more beautiful. The present invention most preferably first method prepares described workpiece,

[0039] In addition, the present invention al...

Embodiment 1

[0044] Such as figure 1 , figure 2 , image 3 as shown, figure 1 The side view of the key cap provided for this embodiment; figure 2 The front view of the key cap provided for this embodiment; image 3 A top view of the key cap provided for this embodiment. The button keycap includes a surface layer 1 and a fixing part 2, in order to distinguish the positional relationship between the surface layer and the fixing part, the black area represents the surface layer, and the white area represents the fixing part. The fixing part is 4 buckles and the connection part between the hook and the surface layer, the hooks are symmetrically arranged on the surface of the surface layer in pairs, and the hook and the connection part are surrounded by the surface layer with a Open frame. The surface layer covers and protects the fixing member.

[0045] Such as Figure 4 , Figure 5 As shown in , it is a schematic diagram of two different hooks, in which Figure 4 is a schematic di...

Embodiment 2

[0048] Place the aluminum alloy foil with a specification of 10×15 in the corresponding cavity of the key cap mold, and close the mold. The mold has 20 cavities in one mold. Take 250g of polyphenylene sulfide and dry at 170°C for 2 hours, put the dried polyphenylene sulfide in the injection barrel, melt and plasticize, the barrel temperature is 316°C, the mold temperature is 135°C, and the injection pressure is 60MPa, The injection time is 2 minutes, and the pressure is held for 1 minute. After cooling and demolding, an ultra-thin keycap with an aluminum alloy surface is obtained, and the thickness of the keycap is 0.2 mm.

Abstract

The invention provides a workpiece, which comprises a surface layer and a fixing piece, wherein the surface layer is arranged on the upper surface of the fixing piece, covers the fixing piece and consists of at least one layer of first materials; the fixing piece is formed by solidifying a second material on the lower surface of the surface layer; the first materials have the metallic characteristic; and the rigidity of the first materials is lower than that of the second material. The surface of the workpiece feels like metal, and the workpiece is thin. The invention also provides electronic equipment using the workpiece.

Description

technical field [0001] The invention relates to the field of material forming and processing, in particular to a workpiece and electronic equipment using the workpiece. Background technique [0002] At present, the market has higher and higher requirements for portable electronic devices such as notebook computers to be thinner, lighter and more aesthetically pleasing, so higher requirements are also put forward for the design of notebook casings. Usually, most of the notebook keyboards are plastic keycaps. Since the mechanical properties of plastic keycaps cannot be guaranteed in an extremely thin case, portable electronic devices such as notebooks using plastic keycaps cannot meet the needs of thinning and thinning. In addition, the single appearance and texture of the plastic keycap cannot meet the increasing requirements of users for product quality, so it cannot meet the demand for aesthetics. Contents of the invention [0003] The technical problem to be solved by t...
