Problems solved by technology

However, the use of magnetic components can only ensure a good gap around it, but the gap away from the magnetic components cannot be uniform; in addition, the placement of magnetic components will occupy the structural space of the notebook, which will not only increase the vo

Embodiment 1

[0039] After the permanent magnet ferrite is crushed, it is mixed with ABS engineering plastics in a weight ratio of 1:9, and then plasticized and granulated to obtain magnetic plastic particles (that is, magnetic resin materials, in which the mass content of magnetic materials is 10%); In the conventional process, the magnetic plastic particles prepared above are added to an injection molding machine for injection molding, and a magnetizable and matched notebook computer screen frame 1 and an operation panel 2 (such as figure 1 shown); and then magnetize the screen frame and the operation panel respectively, so that the opposite surface of the screen frame and the operation panel has S pole magnetism and N pole magnetism respectively; the screen frame and operation panel manufactured above and the notebook After assembling other structural parts of the computer (such as display screen, processor, hard disk, memory, keyboard and the screen cover of the shell, base shell, etc.),...

Embodiment 2

[0042] 1. Preparation of magnetic resin materials

[0043] After crushing the permanent magnet ferrite, mix it with ABS engineering plastic in a weight ratio of 3:7, and then add it to the plastic granulator. The mixed material is heated at 220°C in the barrel of the granulator until it is melted and plasticized. After extruding, cooling and automatic pelletizing, magnetic plastic pellets (the mass content of magnetic material is 30%) are obtained;

[0044] 2. Manufacture magnetizable laptop screen frame and operation panel

[0045] Add the magnetic plastic pellets prepared above into the injection device of the injection molding machine. After the magnetic plastic pellets are heated and plasticized in the barrel at 220°C into a fluid state, they are injected into a closed conventional notebook through the nozzle of the barrel under an injection molding pressure of 80MPa. In the computer injection mold, after cooling the mold to a certain temperature and opening the mold, the...

Embodiment 3

[0049] After the NdFeB magnetic material is crushed, it is mixed with nylon 66 (PA66) at a weight ratio of 6:4, and then plasticized and granulated to obtain magnetic plastic granules;

[0050] The PA66 is injection-molded using a conventional process to obtain the screen frame insert 3 and the operation panel insert 4 (such as figure 2 shown); put the above-mentioned screen frame insert 3 and operation panel insert 4 into corresponding insert molding molds respectively, and then use an injection molding machine to inject the magnetic plastic pellets prepared above into the inserts 3 and 4 respectively. In the insert molding mold, the magnetic plastic particles are injected into the outer periphery of the panels of the inserts 3 and 4 during injection. The molten magnetic plastic particles soften the surface of the inserts in contact with them and diffuse into the inserts. After curing and molding, the screen frame Locally magnetizable regions 5, 6 (such as figure 2 As show...

Abstract

The invention discloses a method for effectively solving the problem of nonuniform gap caused by closing a folding computer. The method comprises the following steps of: (A) manufacturing a magnetizable first shell, which carries a display part, of the folding computer by utilizing magnetic resin materials; (B) manufacturing a magnetizable second shell, which carries an operation part, of the folding computer by utilizing the magnetic resin materials; and (C) respectively magnetizing the first shell and the second shell so that the opposite surfaces of the first shell and the second shell are different in magnetism. The method disclosed by the invention can be used for saving the space and reducing the weight by previously retaining no space for placing a magnet in the folding computer and realizing the purpose that the gap positioned on the integral periphery of the computer is uniform after the computer is closed, thereby effectively improving the appearance and quality of the computer and enhancing the product competitive power; and the method is especially suitable for a majority of ultralight and ultrathin notebook computers.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for effectively solving the uneven gap after folding the screens of a folding computer. Background technique [0002] Laptops, referred to as notebooks for short, have gradually become mainstream products in the computer market because of their small size, light weight, and easy portability. A notebook usually includes a display part (that is, a display screen) and an operation part (including a processor, a hard disk, memory, a keyboard, etc.), and the two parts are carried by the casing and connected in a hinged manner. When not in use, the display part can be rotated to the The operation part is closed, and the screen is locked by the screen lock mechanism, thereby closing the notebook. [0003] Most of the traditional screen lock mechanisms are buckle design, which is a purely mechanical structure consisting of a slidable hook with a relatively smooth front end and a relati...
