Description of the invention: [Technical field of the invention] [0001] The present invention relates to a key, in particular to a multi-directional key. [0002] [Prior Art] With the development of personal computers, notebook computers, network products, communication products, and various consumer electronic products, the functions of such electronic products are increasing, and the number of corresponding buttons is also increasing. On the other hand, all types of portable products are becoming more and more compact, and the contact area of the buttons needs to be reduced as much as possible. However, reducing the button area makes it easy for the user to press multiple keys at the same time or press the wrong button, resulting in misoperation and inconvenience in use. In order to solve the above problems, in the prior art, there are designs for performing a plurality of operation commands using a single button, and such buttons are generally referred to as multi-function buttons or multi-directional buttons. [0004] Multi-directional buttons have been used in remote controls for home appliances such as televisions, refrigerators, and air conditioners, and are mainly used to adjust the volume of electric appliances, adjust the channel, and adjust the temperature and humidity. The multi-directional button usually uses soft rubber as the button material, and the two distal ends of the button are the pressing points of the button. When the user presses one end, the other end of the button can be kept stationary due to the deformation of the rubber material. However, both ends of such a button may be pressed at the same time, causing an unpredictable reaction. Therefore, such a button design is only used in products where the operability is low and the misoperation does not cause adverse consequences. For example, some buttons of the side buttons of some mobile phones, although hard materials such as hard plastic materials are used to make the buttons, the problems such as button linkage cannot be completely avoided. [0005] 094133014 In some devices with higher operational requirements On, such as personal computer, notebook form number A0101 帛 3 pages / a total of 20 贞 0993206177-0 1329331 _ ^ 099 June 10 shuttle is replacing the page computer and other devices, a misoperation may bring significant data loss or other Unpredictable problems occur. For this reason, preventing key linkages becomes a design key for multidirectional buttons. SUMMARY OF THE INVENTION [0006] In view of the above, it is necessary to provide a multidirectional push button that avoids linkage of keys.

Moreover, since the two elastic arms 400 are close to the U-shaped opening 402 opened in the part of the keycap 300, each elastic arm 4〇〇 is divided into two parts, and when the elastic arm 40 is deformed, the two parts generate the opposite elastic force and are used for The original state of the multi-directional button 20 is restored to obtain a better elastic effect. [0016] As shown in FIG. 5, it is a perspective view of the multi-directional button 2 of the present invention assembled on the substrate 24 and the control panel 26. Please also refer to the sixth drawing, which is a cross-sectional view taken along line VI-VI of FIG. 5, in which the tips of the ribs 3〇6 and the semicircular protrusions 308 are in contact with the protrusions 264 on the substrate 24. The upper surface of the keycap 300 is substantially parallel to the plane of the control panel 26 in the absence of external force. [0017] When the multi-directional button 20 is operated, any one end of the two bosses 304 is pressed by an external force. The boss 304 at the end will rotate with the straight line where the two elastic arms 400 are located as the axis 3 2 0. Corresponding contacts 260 on the control panel 26. Since the two protrusions 308 and the ribs 306 have a circular arc shape at the top end, the multi-directional button 20 rotates smoothly. At the same time, the bosses that are not pressed by the external force are correspondingly lifted, thereby completely solving the problem of button linkage. After the external force disappears, with the elastic force of a resilient arm 400, the multi-directional button 2〇 will immediately return to the original state, ready for the next press. "If the middle of the keycap 300 is pressed by the external force' due to the vertical support of the rib 306 , the key cap 3〇〇 can not be pressed 'to avoid mistakes. The rib 306 further functions to reinforce the mechanical strength of the keycap 300 such that the multi-directional button 2 is less susceptible to damage. Please refer to the seventh figure, which is a second embodiment of the present invention. The multi-directional button 500 includes a keycap 510 and two elastic arms 520, the back of the keycap 510 512 094133014 Form No. 101 0101 Page 7 / Total 20 Page 0993206177-0 [0018] 1329331 [0019] After June 10, 099 The replacement page is provided with two ribs 530, two bosses 540 and a connecting arm 550.
