The first housing 12 may include a front frame (2) and a rear cover ^ that is coupled to the front frame 121. The first casing 14 includes an upper cover ΐ4ΐ, and a second reverse ridge is connected to the upper cover 141. The electronic device (1) can be a notebook computer, the first body 12 can be an upper casing, the wire can be placed in a display panel, and the second casing (4) can be used as a lower casing. The main body, and the first housing 12 and the second housing 14 are tied to = magnetic = as a driving force for adsorption and separation. The electronic device 1G further includes an opening-closing mechanism 16' which utilizes a magnetic force to drive the adsorption and separation mechanism between the fresh casings 14 of the first casing 12. /, 1 Referring to Figure 2, Figure 2 is an electronic device of the preferred embodiment of the present invention! The portion of the crucible 16 includes at least a --magnetic element 18 which is split between the front frame 121 and the rear cover 123 of the first housing 12, and the base 2 is disposed on the bottom plate 143. The base (10) contains at least a racking period. In addition, there is a heat 22, the surface of which is formed with at least one rib 22, and the shaft 22 can be a gear 7" or a tread of the tT shaft 22 engraved on the surface of the axle 22. The 221 is rotatably conjugated to the base. The opening and closing mechanism 16 further includes at least a second magnetic element repair, for example, mounted inside the rotating shaft 22 or fixed to the rotating shaft. The first magnetic element 18 interacts to generate % power, such as adsorption force or repulsive force. . The opening and closing mechanism 16 further includes a push-sliding, rib 26 峨 wheel 2G slab 143 - magnetic self-first limb rotation n degrees to change the direction of the thin first driving force between the first and the second member 24. Wherein the anode end), so the first (four): (four) m4U44 〇 2 2 shale adsorption force, so that the first housing 12 can be adsorbed to the second housing ^. The other surface: although the rotating shaft 22 is located at the second angle, the anode end of the first magnetic element 18: the anode end of the element 24 (or the cathode end of the first magnetic element 18) When the magnetic driving force of the first magnetic property such as 8 and the second magnetic magnetic field is a magnetic repulsive force, the first casing 12 can be separated from the second casing 14 by the magnetic repulsive force. x Further 'opening_16' may additionally include a -like element (10) for setting =20 in a workable manner to practice 143. For example, the time component group 28 can contain elements such as bolts, lions, nuts, rivets, and the like.

The elastic member 3 can be disposed between the base 2 and the support wall 145. The elastic member 3Q can be used to provide an elastic restoring force to urge the base 2 to slide relative to the bottom plate (4) when the pusher is released to return the base 20 to a lighter position. In order to break the base 2 () by the elastic returning force of the impurity element μ, the opening and closing mechanism 16 may further include a viewing rib 32 which is attached to the base 20. Reinforcing ribs 32 can be used to increase the structural strength of the base 2 to extend the useful life of the opening and closing mechanism 16. . </ br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> Creating a preferred embodiment of the electronic device 1 in the closed state along the BB section shown in Figure ii is not intended to be the fifth embodiment of the preferred embodiment of the electronic device iw in the open state along the first _ A_A' The cross-sectional view is taken as a cross-sectional view of the B-B shown in the figure i of the M404402 electronic device 10 in the open state. As shown in FIGS. 3 and 4, when the first housing 12 is in contact with the second housing 14, that is, when the electronic device 10 is in the closed state, the secret 26 of the opening and closing 16 has not been pressed by the user. The ridges 221 of the rotating shaft 22 are halved on the teeth 201 of the susceptor 2 at the first angle, and the first magnetic element 18 and the second magnetic element 24 are in a state of opposite pole attraction. For example, the anode of the first magnetic element 18 faces the cathode of the second magnetic element ,, or the cathode of the first magnetic element i8 faces the second magnetic field, so the first housing 12 and the second _14 of the electronic device (4) can be It is closely adhered by the magnetic attraction force of the two magnetic materials. On the other hand, as shown in Figs. 5 and 6, when the electronic device 1 is to be turned on, the user can push the push button 26 to drive the base 2 to slide relative to the wall 145 of the second housing 14. Since the tooth 221 of the rotating shaft 22 is sprayed on the rack 2 〇 基座 of the base 2, the rotating shaft u is driven by the push button 26 and rotates from the first button to the second button, that is, mounted on the second button. The first-magnetic section 18 on the auxiliary 22 rotates - ten degrees, so that the first magnetic element 18 and the second magnetic tree 24 are in the same polarity repulsive state, for example, the anode of the first magnetic element 18 faces The second magnetic element is an anode, or the cathode of the first magnetic element μ faces the cathode of the second magnetic element 24. Therefore, the first housing *12 and the second housing 14 of the electronic device (1) can be separated by two magnetic elements The magnetic repulsive force is separated to drive the second body 12 to pivot relative to the second housing 14 to form a space between the two housings, so that the user can step up and raise the first housing 12. Next, when the user releases the force applied to the push button 26, the reading element 3 () can be used to drive the seat π back to the bottom plate (4). The initial position of the sea. Since the first housing 2 is far away from the second housing 10 M404402 14 , the first magnetic element 18 and the second magnetic element 24 are formed even if the base 20 rotates the rotating shaft from the second angle to the first angle. The magnetic attraction force is not enough to drive the first housing 12 to pivot in the direction of approaching the second housing 14, so that the electronic device 1 can be adjusted to the deployed state according to the user's needs. Compared with the prior art, the author uses the relative/moon motion mechanism between the base and the bottom plate of the second casing to drive the shaft to rotate, so that the second magnetic component disposed in the rotating shaft can follow the rotation angle of the rotating shaft. And changing its magnetic pole property toward the first magnetic element. When the electronic device is to be housed, the user can make the anode end (or cathode end) of the second magnetic element = toward the cathode end of the first magnetic element (scale extreme), and generate magnetic between the two different magnetic poles. Adsorption force, when the electronic device is to be turned on, 'the user can drive the rotation shaft to rotate 'to make the anode end (or cathode end) of the second magnetic element face the anode end (or cathode end) of the first magnetic element. The two magnetic poles produce a magnetic repulsive force. In this way, the opening and closing mechanism of the present invention only needs to use two kinds of miscellaneous components, that is, the magnetic pole direction of the magnetic component can be rotated manually, so that the magnetic driving force can be generated according to the operation requirement, so the creation can save the magnetic component. The number of uses to reduce the manufacturing cost of the opening and closing mechanism' and the opening and closing machine of the present invention can effectively prevent the magnetic force from interfering with each other due to the use of too many magnetic components, and can effectively improve the magnetic properties. The strength of the driving force, so the creation has better operational convenience.
