[Prior Art] [0002] With the increasing functions of portable electronic devices such as mobile phones and personal digital assistants (PDAs), many portable devices, such as keyboards and touch panels, are portable. The electronic device also has a function button (ie, a side key) on its side wall, which can be used for quick operation of the volume control, camera focus adjustment, camera switch and the like of the portable electronic device. [0003] Conventional button components Most of them are provided with a button and a spring element, and the spring element is mounted on one side of the button. When the button is pressed, the button triggers a function circuit corresponding to the switch in the portable electronic device, and the spring element is elastically deformed; after the button is released, the elastic element is the button Provides a restoring force to return the button to its original position. [0004] However, most of the spring elements need to be mounted on the buttons with hooks and the like, which is easy to make the button elements have a complicated structure, high manufacturing cost, and occupy a large space, which is not conducive to the current portable type. The trend of miniaturization of electronic devices. In addition, after the spring element is used for a long period of time, it generally loses its own elasticity due to aging of the mechanical structure, and may not provide sufficient elastic force to drive the pressed button to return to the original position in time to cause inconvenience.

The two protrusions 231 are respectively located on opposite sides of the accommodating groove 211. The end of each of the bumps 231 extends vertically in a direction away from the bottom wall 23 to form a block 233. When the chain 1 按压 is pressed, the block 233 abuts against the hook 1333 to realize the limit of the elastic arm 133 and avoid the shifting element of the key structure 10. . Referring to FIG. 2 to FIG. 4, when the portable electronic device 1 is assembled, a double-shot injection molded button structure 1 is first mounted on the housing, that is, the button η is pressed. The genus portion 113 is disposed outside the sidewall 213 through the accommodating groove 2U through the accommodating groove 2U, and the apex portion 13193b is held by the positioning block 2153. The holding wall 1313 is abutted against the side wall 21_, and the card fishing 1333 is held by the card block 233. Then, the two switches 3 () are electrically connected to the circuit board H, and then the circuit board is flanked into the shell (4), and the off 3G is opposite to the resist 1311. The board 4 is opposite to the limiting block 1317, that is, the assembly of the portable split electronic device 100 is completed. Referring to FIG. 2 to FIG. 4, when the button structure is used, the end portion of the pressing portion 113 of the button U is pressed, so that the pressing portion 113 pushes the form number A0101 篦A hundred/+*, one [0018] [0018] 00 [0020] The corresponding end of the elastic member 13 is moved toward the switch 3Q, and the hook 1333 of the bullet #133 is cut on the block 233 to achieve _ The limit 'the connecting portion 1331 is elastically stretched and deformed toward the switch 30 until the abutting block 1311 abuts and triggers the opening _. When the button π is released, the elastically stretched connecting portion 1331 returns to the initial state, and the main body 丨 31 and the button 11 are returned to the original position. In the present embodiment, when the portable electronic device i is concealed and the button junction is 'not used, the distance between the gate and the resistor 13n is 0.1 mm; the circuit board is limited to The distance between the bit blocks 1317 is 〇. 25 mm. When the user presses the button u, the top block 1311 is firstly abutted and the switch 3 is triggered. When the user is too strong or the button 11 receives a collision, the limit block 1317 is resisted. The circuit board 4'' thus prevents the abutting block 1311 from over-pressing the switch 3A and damaging the switch 30. In the portable electronic device 100 of the preferred embodiment of the present invention, the button structure 1 is mounted on the housing 20, and the button 11 of the button structure 10 is pressed to cause the bomb.
