Problems solved by technology

[0002] At present, the characteristics of the magnets in the tablet computer and keyboard connection device sold on the market are: simple processing and large quantity; its disadvantage is: it is inconvenient to install the magnets, and six magnets must be loaded separately; and when applied to large-sized tablet computers When it is connected with the keyboard, the adsorption force of the two is not strong enough, and the effect is not good; when the tablet uses a capacitive screen, the single-piece magnet installation method will interfere with the operation of the capacitive screen and affect the use effect

Embodiment Construction

[0017] The key of the present invention is: the magnetization arrangement of the five magnets of the magnetic assembly is assembled according to the Halbach array, and an iron bar is stuck on the weak magnetic surface of the magnet; between the iron bar and the magnet is Fixed with glue. The thickness of the iron bar is between 0.4-1.0mm, and its thickness is determined according to the shielding effect and the suction requirements of the tablet computer.

[0018] see Figure 1-Figure 4 , Embodiment 1: After the size of the five magnets of the magnetic assembly is processed, press figure 1 The magnetic direction requires that after magnetization, the distribution of the magnetic field lines of the five magnets arranged according to the Halbach array is as follows: image 3 ; Brush glue on the iron bar 3, and press the first magnet and the second magnet in turn figure 2 Fixed on the iron bar, baked at 50°C for 5-10 minutes, the distribution of the magnetic force lines after...

Abstract

The invention discloses a keyboard with a Halbach magnetic module, comprising a magnetic module; the magnetic component is composed of five magnets: first magnets and second magnets, and an iron bar; the five magnets are arranged according to a Halbach array mode and are adhered on the same iron bar. The module assembled by this mode has the maximum magnetic force on the face without the iron bar; the magnetic force at the iron bar side is the minimum; therefore the performance of the magnet is utilized fully, the maximum adsorption force is realized; simultaneously the keyboard can be conveniently and simply installed on a tablet personal computer, and the interference of the magnetic field of the magnets to the function of an electronic element is reduced.

Description

technical field [0001] The invention relates to magnet technology, in particular to an adsorption magnetic component suitable for connecting a tablet computer with a keyboard and having a shielding function. Background technique [0002] At present, the characteristics of the magnets in the tablet computer and keyboard connection device sold on the market are: simple processing and large quantity; its disadvantage is: it is inconvenient to install the magnets, and six magnets must be loaded separately; and when applied to large-sized tablet computers When it is connected with the keyboard, the adsorption force of the two is not strong enough, and the effect is not good; when the tablet computer adopts a capacitive screen, the single-piece magnet installation method will interfere with the operation of the capacitive screen and affect the use effect. Contents of the invention [0003] The purpose of the present invention is to: propose a kind of magnetic component device th...
