使用時，只要按壓按鍵10的一端，對應按鍵10的該被按壓端部的支撐肋344受壓力而發生彈性變形，從而按鍵10上該被按壓端部沿固定結構30的旋轉栓3460旋轉。與此同時，按鍵10上被按壓處及其周邊受壓力而彈性變形，略微往下凹陷，從而帶動第三定位柱16和觸點14下壓，此時彈簧160被壓縮，觸點14觸碰電路板20，從而完成信號的輸入。撤銷按壓在按鍵10一端的壓力後，按鍵10在支撐肋344和彈簧160的彈性回復力的作用下沿旋轉栓3460反向旋轉，直至回復為初始狀態。通過多次按壓按鍵10的兩端部即可實現信號的多次輸入，從而方便的調節電子設備99的音量。 In use, as long as one end of the button 10 is pressed, the supporting rib 344 of the pressed end portion of the corresponding button 10 is elastically deformed by the pressure, so that the pressed end portion of the button 10 rotates along the rotating pin 3460 of the fixed structure 30. At the same time, the pressed portion of the button 10 and its periphery are elastically deformed by the pressure, and are slightly depressed downward, thereby driving the third positioning post 16 and the contact 14 to be pressed down, at which time the spring 160 is compressed and the contact 14 is touched. The board 20 completes the input of the signal. After the pressure pressed at one end of the button 10 is cancelled, the button 10 is reversely rotated along the rotary pin 3460 by the elastic restoring force of the support rib 344 and the spring 160 until the initial state is restored. By repeatedly pressing both ends of the button 10, multiple input of signals can be realized, thereby conveniently adjusting the volume of the electronic device 99.
本發明提供的電子設備99通過在其按鍵結構200的固定結構30上設置了具有彈性的支撐肋344抵接於按鍵10的中軸線位置，從而在按鍵10被按壓時，支撐肋344和彈簧160均發生彈性形變，一起支撐按鍵10以控制按鍵10的旋轉度；而在作用於按鍵10上的外力撤銷後，支撐肋344和彈簧160均提供彈性回復力以使按鍵10回復至初始狀態。從而減輕了彈簧160的負荷，延長了彈簧160的使用壽命，增強了按鍵結構200的穩定性。與此同時，即使彈簧160因重複使用產生彈性疲乏甚至喪失彈性時，按鍵10在支撐肋344的支撐及彈性回復力作用下，仍可在沿旋轉栓3460旋轉並完成信號輸入後，恢復到初始的平衡狀態。 The electronic device 99 provided by the present invention abuts the central axis position of the button 10 by providing elastic support ribs 344 on the fixing structure 30 of the button structure 200, so that when the button 10 is pressed, the support rib 344 and the spring 160 are provided. Elastic deformation occurs, and the button 10 is supported together to control the degree of rotation of the button 10. After the external force acting on the button 10 is cancelled, both the support rib 344 and the spring 160 provide an elastic restoring force to return the button 10 to the initial state. Thereby, the load of the spring 160 is alleviated, the service life of the spring 160 is prolonged, and the stability of the button structure 200 is enhanced. At the same time, even if the spring 160 is elastically fatigued or loses elasticity due to repeated use, the button 10 can be restored to the initial state after being rotated along the rotary bolt 3460 and completing the signal input under the support of the support rib 344 and the elastic restoring force. Balanced state.
