Please refer to FIG. 6 , which is a schematic diagram of the operation of the electronic device 2 with the function of preventing accidental touch. In FIG. 6, the electronic device 2 is in an open state, the cover 21 is located at an open position M1 with respect to the base 22, and the magnetic member 211 is away from the magnetic unit 312. Due to the elastic force generated by the elastic member 32, the retaining member 31 is held at a predetermined position L1, so that the guard mechanism 3 of the present embodiment does not sway due to the movement of the electronic device 2. When the stopper member 31 is held at the predetermined position L1, the spacer portion 3131 is spaced apart from the pressing member 251 by a distance. Therefore, the pressing member 251 can be pressed such that the first switching element 252 contacts or is pressed against the second switching element 253.

Please refer to FIG. 7 , which is a schematic diagram of the operation of the electronic device 2 with the anti-touch function of the present invention. In FIG. 7, the cover 21 is located at a closed position M2 with respect to the base 22, and when the cover 21 is covered by the base 22 and the magnetic member 211 is adjacent to the magnetic unit 312, a magnetic element 211 is generated between the magnetic element 211 and the magnetic unit 312. The magnetic force F1 of the phase attracting force, because the elastic force provided by the elastic member 32 is smaller than the magnetic force F1, the magnetic unit 312 is attracted by the magnetic member 211, so that the magnetic unit 312 rotates around the rotating shaft member 34, and drives the limiting body 311 and the limiting unit. 313 rotation. After the position limiting unit 313 is rotated, it is located at a protective position L2, and the abutting portion 3132 is brought into contact with the pressing member 251.

In the present embodiment, the base 22 further includes a stop element 224. The stop element 224 is located between the pressing element 251 and the magnetic unit 312, and after the magnetic element 211 is adjacent to the magnetic unit 312 to rotate the magnetic unit 312, the magnetic unit 312 is in contact with the stop element 224. Therefore, the stop member 224 can restrict the magnetic unit 312 from being located at the guard position L2 and can prevent the magnetic unit 312 from contacting the pressing member 251.

When the user moves the electronic device 2 and applies the force to the cover 21 and the base 22, since the pressing member 251 is contacted by the abutting portion 3132, the surface of the pressing member 251 and the operation surface 221 of the base 22 can be located at the same horizontal plane P1. Up, that is, the pressing member 251 is not depressed, so that the first switching element 252 and the second switching element 253 are not in contact to generate a control signal. Further, since the pressing member 251 is not pressed down, the lid body 21 and the display screen 23 are not bent, and damage of the display screen 23 can be avoided.

In addition, when the cover 21 is restored to the open position M1, the magnetic force F1 is reduced between the magnetic member 211 and the magnetic unit 312, and is smaller than the elastic force. Therefore, the stopper member 31 returns to the predetermined position L1 of Fig. 6.

In summary, the electronic device with the anti-touch function of the present invention has a protection mechanism. When the cover of the electronic device is covered on the base, the protection mechanism contacts the pressing member of the button assembly to prevent pressing. The component is accidentally touched and prevents the display screen of the cover from being bent and broken.
