New description: [New technical field] This work is about a magnetic device, especially a magnetic device for electronic number borrowing. [Previous Techniques 1. Referring to Figure 1, Figure 1 shows a conventional notebook computer 1. Fig. 2a is a magnified view showing the hook 1 of the notebook computer 1, and Fig. 2B is a cross-sectional view showing the card slot 120 of the pen & When the card slot 12A on the keyboard base 12 and the hooks 1b on the panel cover 10 are engaged with each other, the panel cover 1A and the keyboard holder 12 of the notebook computer 1 are in a closed state. In contrast, when the card slot 12A on the keyboard base 12 and the hook 1b on the panel cover 10 are separated from each other, the panel cover 1A and the keyboard holder 12 of the notebook computer 1 are in an open state. However, the hook 1〇〇 and the card slot 12 may fail due to frequent use. b—In addition, the hook 100 is a convex portion compared to the panel cover 1〇, and thus is easily damaged by impact. Compared with the keyboard base 12, the card slot 12 is a recessed portion, so that it is easy to accumulate dirt. In addition, the appearance of electronic products has become a trend, and the design of the hook 100 and the card slot 12 is clearly in conflict with this situation. ^ Therefore, the main scope of this creation is to provide an electronic device for solving the above problems. [New Content] One of the scope of the present invention is to provide a magnetic device for an electronic device. The electronic device includes an upper cover and a base, and the upper portion is pivotally connected to the base. In a preferred embodiment of the present invention, the magnetic device includes a magnetic component and a magnetic sensing component. The magnetic element is disposed within the upper cover. The magnetic sensing element M318746 is disposed within the base and has a position corresponding to the magnetic element. When the upper cover is covered with the base, the upper cover is attracted to the base by a magnetic force. The magnetic force is present between the magnetic element and the magnetic sensing element, and the magnitude of the magnetic force varies with the distance between the magnetic element of the upper cover and the magnetic sensing element of the base. Compared with the prior art, the magnetic device according to the present invention can adsorb the upper cover of an electronic device to the base of the electronic device by providing a magnetic force: Root & The magnetic device of the present invention not only improves the electronic device Appearance, there will be no fatigue failure after frequent use. Furthermore, the magnetic device according to the present invention can also be used as a switch for controlling the power of the display panel of one of the electronic devices. # About the merits and spirit of this creation can be further understood by the following details of the creation and the drawings. [Embodiment] Please refer to Figure 3. Figure 3 is a diagram showing a magnetic device for an electronic device 2 in accordance with a preferred embodiment of the present invention. The electronic device 2 includes an upper cover 2 and a base 22, and the upper cover 20 is pivotally connected to the base 22. As shown in FIG. 3, the magnetic device includes a magnetic element 2A and a magnetic sensing element 220. In practical applications, the magnetic component 200 can be a permanent magnet, and the magnetic sensing component 220 can be made of a ferr〇-material. In this embodiment, the magnetic sensing element 220 is an iron piece. The magnetic component 200 is disposed within the upper cover 20. The magnetic sensing element 220 is disposed within the base 22 and has a position corresponding to the magnetic element 2〇〇. . As shown in FIG. 4, when the upper cover 20 is covered with the base 22, the upper cover 20 is attracted to the base 22 by a magnetic force. The magnetic force is present between the magnetic element 200 and the magnetic sensing element 220, and the magnitude of the magnetic force varies with the distance between the magnetic element 200 of the upper cover 20 and the magnetic sensing element 220 of the base 22. M318746 In practical applications, the magnetic device may further include a reed switch (not shown). The reed switch has a glass tube, and two reeds are respectively mounted at one end of the glass tube. Further, the inside of the glass tube is filled with an inert gas. The contact portion of each magnetic reed may be plated with ruthenium or iridium to prevent the contact portion from being oxidized. When the magnetic field around the reed switch reaches a predetermined intensity, the two magnetic reeds will be magnetized and contact each other due to different polarities. When the magnetic field around the reed switch is lower than the predetermined intensity, the two magnetic reeds will be separated by the disappearance of magnetization. In short, one of the open/short states of the reed switch is related to the magnitude of the surrounding magnetic field. In one embodiment, the reed switch can be used to control the power of a display panel (not shown) of the electronic device 2. When the angle between the upper cover 2〇 and the base 22 is greater than a threshold angle, the magnetic field around the reed switch will be lower than the predetermined intensity, and the power of the display panel will be opened by the reed switch. The status is turned on. When the upper cover 2G and the base 22 are smaller than the door angle, the magnetic field around the reed switch will reach the predetermined intensity, and the power of the display panel will be in a closed state. is closed. Referring to FIG. 4 again, in practical applications, the magnetic device includes an electromagnetic if (iHgnetic shielding) element 202' for mating with the magnetic element 200. The electromagnetic shielding element 2〇2 has a high magnetic permeability. In addition to avoiding the magnetic force issued by the magnetic element 2G0 to the center, the ίί 202 can also reduce the influence of the external magnetic field on the magnetic device. 200. If the electromagnetic shielding tree 2G2 is adjacent to the magnetic line of the magnetic component, the magnetic flux is concentrated on the magnetic sensing element 22A. - The magnetic device created by the magnetic book can not make the appearance of the electronic touch by the magnetic device created by it, and there is no risk of fatigue failure after the M318746. Further, the magnetic device according to the present invention is capable of controlling the switching of the power of the display panel of one of the electronic devices. ...
