The locking mechanism 3 includes a second magnetically permeable member 32 disposed in the screen casing 2 adjacent to the card slot 21, wherein the second magnetically permeable member 32 is a magnet. When the screen casing 2 is in the cover position of the top surface of the main machine 1 (as shown in FIG. 5), the magnetic force transmitted through the third magnetic conductive member 吸引 attracts the first magnetic conductive member 31 to move up and down. The opening (1) is opened and the card is in the card slot 21. Specifically, although the first and second magnetic conductive members 31, the magnetic conductive metal members and the magnets of the present embodiment are described as an example, the practical application - the magnetic conductive members 31, 32 are also The magnets and the magnetically permeable metal 6 M380504, or the first and second magnetically permeable members 31 and 32 are respectively magnets, and are not limited to the design manner disclosed in the embodiment. The first magnetically conductive member 31 includes a metal card block 311 for latching in the card (4), and a limiting portion 312 disposed on the outer surface of the card block 311. The main body casing 1 further includes a housing The collision portion 12 in the groove u and above the limiting portion 312. The stopping portion 12 is configured to allow the limiting portion of the first magnetic conductive member 31 to abut to restrict the upward movement of the first magnetic conductive member 31, and prevent the first magnetically conductive member 3 from being detached from the host through the opening lu The casing i, whereby the first magnetically conductive member 31 can be placed in an initial position (shown in FIG. 3) accommodated in the accommodating groove η, and is attracted to the second magnetically permeable member 32.

Move to the initial position, at this time, the screen housing 2 and the main unit casing 呈 are in a locked state, the first magnetic conductive member 31 is accommodated in the accommodating groove U and the top end of the tamping block 311 is substantially opposite to the main body casing 1 top surface is aligned. Thereby, the first magnetic conductive member 31 does not expose the top surface of the main casing 1 and causes a user's influence on the use. It should be noted that, in the design, when the latching block 311 is in the latching position, the limiting portion 312 can also be spaced apart from the blocking portion 12 by a distance without abutting the blocking portion 12, as long as the screen housing 2 During the process of being pulled up, the limiting portion 312 can be blocked by the blocking portion 12 without the card block 3Π continuing to move up, and the card block 311 is not used in the embodiment. In the position of the engine, the limiting portion 312 is limited to abut against the bottom surface of the blocking portion 12. Preferably, in the present embodiment, the latching block 311 includes a carding portion 314 located on the upper side of the limiting portion 312 for latching in the card slot 21, and - located at the lower side of the limit 4 312 and having an external control greater than The base of the outer diameter of the Snapper 314 is permeable to the base of the base P 3 15 so that the bottom surface of the limiting portion 3 丨 2 can abut against the base portion 31 $ , whereby the limiting portion 312 and the stopping portion When the 12 is abutted, the force blocked by the stopper portion 312 by the stopper portion 12 can be uniformly transmitted to the base portion 315, so as to avoid the situation that the limit stop 312 is skewed due to the reverse. Furthermore, the locking mechanism 3 further includes an elastic pad 33 disposed in the receiving groove U for abutting against the bottom surface of the base portion 315 of the locking block 311. The elastic pad 33 is made of rubber or silicone material and is designed to pass through the elastic pad 33. The force that can absorb the downward movement of the first magnetic conductive member 31 can avoid the friction and abrasion caused by the impact, in addition to the noise generated by the collision of the main body casing 311. Of course, at the time of design, the latch block 311 can also be designed to have the same outer diameter of the latch portion 314 and the base portion 315 as shown in FIG. As shown in FIG. 8 and FIG. 9, another embodiment of the first magnetic conductive member 31, the limiting portion 312 of the first magnetic conductive member 31 is integrally formed by the outer surface of the latching block 311. The outer portion is protruded outward, and the outer diameter of the latch portion 314 and the base portion 315 are designed to be the same. Preferably, the outer diameter of the base 315 of the latch block 311 can also be designed to be larger than the outer diameter of the latch portion 314 as shown in FIG. As shown in FIG. 11 , in another embodiment of the first magnetic conductive member 31 , the first magnetic conductive member 31 ′′ includes a plurality of spacers 312 ′′ disposed on the outer surface of the latching block 311 , and The latch portion 314 is designed to be the same as the outer diameter of the base portion 315. Preferably, the outer diameter of the base portion 3 15 of the latch block 311 can also be designed to be larger than the outer diameter of the latch portion 314 as shown in FIG. As shown in FIG. 13 and FIG. 14 , the second preferred embodiment of the electronic device of the present invention is that the overall structure and operation mode of the electronic device 110 are substantially the same as the first preferred embodiment. It is disposed on the screen casing 2, and the card slot 21 is disposed on the main casing 丨. The screen casing 2 includes a stopping portion 12 located in the locking groove 11 for abutting the limiting portion 312 of the first magnetic guiding member 31 to restrict the moving stroke thereof. The main body casing 1 includes a defining slot 21 And a base wall 22 for the second magnetic conductive member 32 to be adhered, and a plurality of hooks 24 protruding from the back surface of the base wall 22 for engaging the second magnetic conductive member 32. When the screen casing 2 is in the closed position, the receiving groove 11 on the screen casing 2 corresponds to the position of the card slot 21 on the main casing 1, and the first magnetic field is attracted by the magnetic force of the second magnetic guiding member 32. The latching block 311 of the member 31 and the first magnetically conductive member 31 are caused by gravity, so that the latching block 311 is moved downward in the direction of the arrow ΙΠ. When the limiting portion 312 of the first magnetically permeable member 31 abuts against the top surface of the blocking portion 12, the latching block 311 can no longer move up. At this time, the latching block 311 is located at the bottom end portion of the opening 111. And the card is placed in the latching position in the card slot 21, so that the screen casing 2 and the main body casing 1 are locked. As shown in FIG. 15 and FIG. 16 , when the user wants to turn on the screen casing 2, the screen casing 2 is pulled upward in the direction indicated by the arrow VI. In the process of pulling the screen casing 2, the first The limiting portion 312 of the magnetic conductive member 31 abuts against the blocking portion 12 ′ so that the locking block 311 can be gradually separated from the card slot 21 , and when the card clamping block 3 ι is completely separated from the card slot 21 , the screen casing 2 and the main body casing 1 The lock state is released. If the angle of rotation of the screen casing 2 is less than a critical angle, the first guide 10 M380504 magnetic member 31 still causes the latch block 311 to pass through the opening ill due to the gravity relationship, and the user can press the first magnetic conductive member 3 by finger pressing. 1Reset it to the initial position where the critical angle refers to an angle of 90 degrees between the screen casing 2 and the main casing 1. Preferably, as shown in Fig. 16, if the angle at which the screen casing 2 is rotated is greater than the critical angle, the first magnetically conductive member 31 automatically resets the latching block 3 11 to the initial position due to the gravity relationship. In summary, the electronic devices 10A, 11() of the embodiments can pass through the initial position of the first magnetically conductive members 31, 31, 31" of the locking mechanism 3 in the receiving slot. The second magnetic conductive member 32 is attracted to pass through the opening U1 and is moved between the latching positions in the card slot 21, so that the screen casing 2 can be in a released state or a locked state with respect to the main casing 1 The change can indeed achieve the purpose of the present invention.
