PORTABLE ELECTRONIC DEVICE

The present invention relates to an electronic device, and more particularly, to a portable electronic device.

In a common notebook computer device, the keyboard is integrated into the host, and the user cannot easily detach the keyboard from the host according to operational requirements. Generally speaking, a keyboard can be roughly divided into a side-by-side alphabetic keypad and a numeric keypad. In order to improve the convenience of the user's operation, a design of a detachable numeric keypad is proposed for the user to detach the numeric keypad from the host according to operation requirements. The operation functions provided by the common numeric keypad are relatively limited, and it is difficult to meet the operational requirements of controlling the cursor, opening application menus, switching application items, browsing application items, selecting application items, and executing applications.

The present invention provides a portable electronic device with excellent operational convenience and operational flexibility.

The present invention provides a portable electronic device, which includes a first body, a second body pivotally connected to the first body, and a first keyboard detachably disposed on the first body. The first keyboard includes a casing, a plurality of keys, a first carrier, a knob, a magnet, a second carrier and an electromagnet. The plurality of buttons are arranged on the casing. The first carrier is movably disposed in the housing. The knob is arranged on the first carrier, and the top surface of the knob is exposed and higher than the top surface of the casing. The magnet is fixed on the first carrier. The second carrier is fixed in the casing and is located above the first carrier. The electromagnet is fixed on the second carrier corresponding to the magnet. The energized electromagnet generates a magnetic attraction force to the magnet, so as to drive the first carrier to move toward the second carrier, and increase the height difference between the top surface of the knob and the top surface of the casing.

Based on the above, in the portable electronic device of the present invention, the first keyboard adopts a detachable design and integrates a knob. Therefore, the user can control the cursor, open the application menu, switch application items, browse the application items, select the application item and execute the application through the knob. On the other hand, the knob can be adjusted up by magnetic force, which is convenient for the user to operate. Therefore, the portable electronic device of the present invention has excellent operational convenience and operational flexibility.

The carrier 133 and the second carrier 136 . When the first carrier 133 moves toward the second carrier 136 along the direction D, the plurality of springs 138 are compressed and elastically deformed.

Once the power to the electromagnets 137 is stopped, the magnetic attraction force acting on the first carrier 133 disappears, and the elastic restoring force of the springs 138 can drive the first carrier 133 to move away from the second carrier 133 along the direction D The carrier 136 is placed so that the top surface 134a of the knob 134 is flush with the pressing surface 132a of each button 132 again, and the height difference between the top surface 134a of the knob 134 and the top surface 131a of the housing 131 is restored to H1.

Referring to FIGS. 6 and 7 , the first carrier 133 has a plurality of protruding posts 133 a extending toward the second carrier 136 , and the plurality of protruding posts 133 a pass through the second carrier 136 . The plurality of protruding posts 133a are symmetrically distributed on the periphery of the knob 134, and the plurality of springs 138 are sleeved on the plurality of protruding posts 133a. Further, since the extending direction of each protruding post 133a is parallel to the direction D, and the plurality of protruding posts 133a are symmetrically distributed on the periphery of the knob 134, it can ensure that the first carrier 133 reciprocates smoothly along the direction D . On the other hand, the plurality of protruding posts 133a can prevent the plurality of springs 138 from being deflected during telescopic deformation.
