Next, the opposite ends of the rotary shaft 42 are respectively passed through the right cover 435 and the left cover 433 of the shock absorbing device 43, so that the shock absorbing device 43 is fixed to the rotary shaft 42. Then, the shaft body 426 is affixed to the left and right side walls 413 of the first fixing member 41 by threading or welding through the positioning member 45 'shaft 426 disposed on both sides of the first fixing member 41; The other end is inserted into the shaft fixing hole 442 of the second fixing member 44, and the shaft body 426 is connected with the second fixing member 44. Finally, the buffer device 43 is fixed to the second fixing by welding or screwing. On piece 44. After the assembly is completed, the arm 421 and the shaft 426 of the rotary shaft 4 are completely abutted against the solid body 431 inside the buffer unit 43, and the inside of the buffer unit 43 is divided into two closed chambers and 6. In the present embodiment, the positioning member 45 is composed of a spring piece 451, a spacer 452, and a nut 453, which are sequentially put on the shaft body 426. [0017] Referring again to FIGS. 1 and 2', the rotating shaft 40 is coupled to the cover 20 and the body 30 of the electronic device 100 by screw connection. Specifically, the cover bracket 21 of the cover body 2 is inserted into the mounting hole 410 of the first fixing member 41 of the rotating shaft 40, and the cover screw 22 sequentially passes through the 099100471 on the front and rear sides 414 of the first fixing member 41. Form No. A0101 Page 7 of 17 0992001029-0 201124643 The screw hole 411 and the cover through hole 2〇1 on the cover bracket 21 fix the cover 20 in the first fixing member 41. The body screw 443 sequentially passes through the fixing hole 441 on the top surface 444 of the second fixing member 44 and the body through hole 3〇1 of the body 30 corresponding to the fixing hole 441 to fix the pumping 40 to the body 30. It is to be understood that the shaft 4 can also be coupled to the cover 20 and the body 30 by other means of attachment, such as welding, as needed. [0018] Please refer to FIG. 4 at the same time. During use, when the cover 20 is opened, the cover 20 drives the rotating shaft 40 to rotate. Since the damper device 43 is fixedly coupled to the second fixing member 44, and the rotating shaft 40 rotates with the rotation of the cover body 2, the relative movement between the rotation i./shaft 42 and the buffer device 43 and the solid 431 is a rotating shaft. When the 42 is rotated, the chamber A or B of the cushioning device 43 is pressed. At the same time, the circulation of gas can be performed between the two chambers A and β formed by the rotating shaft 42 of the rotating shaft 40 and the body 431 of the buffering device 43 by the vent holes 424 on the arms 421 of the rotating shaft 42. [0019]
正常使用時，由於轉軸的轉動速度穩定平鍰，所以兩腔 室Α和Β之間氣體能平穩順暢的藉由通氣孔424進行相互流 通’兩腔室之間壓強也能夠達到平衡，電子設備轉動穩 U 定。當用戶快速開啟或關閉電子設備時，由於轉轴也 跟著瞬間快速的轉動，旋轉軸42會迅速擠壓緩沖裝置43 其中的一個腔室A或B。由於旋轉軸42的迅速轉動样壓，a 和B腔室之間的氣體不能在短暫的時間内藉由通氣孔424 順暢流通，即不能在短暫的時間内平衡調節兩腔室之間 的氣壓。因兩腔室之間壓強的不同’故腔室A或β會產生 一個與旋轉軸42旋轉擠壓方向相反的力。即轉細4〇在轉 動中會遇到與轉動方向相反的阻力，所以這個相反的阻 099100471 表單編號A0I01 第8頁/共π頁 0992001029-0 201124643 力會迫使旋轉軸4 2的轉動速度逐漸減慢。因此電子設備 100不會因為用戶的快速開啟或關閉造成轉軸40的打滑或 蓋體20夾傷用戶，從而避免了用戶的不當使用造成轉軸 40或電子設備100的損壞及人員的損傷。 [0020] 另外，本領域技術人員還可在本發明精神内做其他變化 ，當然，這些依據本發明精神所做的變化，都應包含在 本發明所要求保護的範圍之内。 【圖式簡單說明】 [0021] 圖1係一較佳實施方式的電子設備的立體圖。 Ο [0022] 圖2係圖1的電子設備的分解圖。 [0023] 圖3係圖2中電子設備的I處的放大圖。 [0024] 圖4係圖2中電子設備的A-A向剖面圖。 【主要元件符號說明】 [0025] 電子設備：100 [0026] 蓋體：20 〇 [0027] 本體：30 [0028] 轉軸：40 [0029] 第一固定件：41 [0030] 旋轉軸：42 [0031] 緩沖裝置：43 [0032] 第二固定件：44 099100471 表單編號A0101 第9頁/共17頁 0992001029-0 201124643 [0033] 定位件：45 [0034] 安裝孔：410 [0035] 螺釘孔：411 [0036] 頂壁：412 [0037] 側壁：413 [0038] 側面：414 [0039] 支臂：421 [0040] 頂面：422 [0041] 螺釘調節孔：423 [0042] 通氣孔：424 [0043] 螺釘：425 [0044] 軸體：426 [0045] 側面：4 2 7 [0046] 實體：431 [0047] 軸體穿孔：432 [0048] 左蓋板：433 [0049] 中空腔體：434 [0050] 右蓋板：435 [0051] 固定孔：441 099100471 表單編號A0101 第10頁/共17頁 0992001029-0 201124643 [0052] [0053] [0054] [0055] [0056] [0057] [0058] ❹ 轴體固定孔：442 本體螺釘：443 頂面：444 侧面：44 5 蓋體支架：21 蓋體螺釘：22 本體通孔：301In normal use, since the rotation speed of the rotating shaft is stable and flat, the gas between the two chambers and the crucible can smoothly and smoothly flow through the vent hole 424. The pressure between the two chambers can also be balanced, and the electronic device rotates. Stable. When the user quickly turns the electronic device on or off, the rotating shaft 42 quickly presses one of the chambers A or B of the cushioning device 43 because the rotating shaft also rotates in an instant. Due to the rapid rotational pressure of the rotating shaft 42, the gas between the chambers a and B cannot be smoothly circulated through the vent 424 in a short period of time, i.e., the air pressure between the two chambers cannot be balanced and adjusted in a short period of time. Due to the difference in pressure between the two chambers, the chamber A or β produces a force opposite to the direction in which the rotary shaft 42 is rotated. That is, the rotation of the 4 〇 will encounter the resistance opposite to the direction of rotation during the rotation, so the opposite resistance 099100471 Form No. A0I01 Page 8 / Total π page 0992001029-0 201124643 Force will force the rotation speed of the rotating shaft 4 2 to gradually decrease slow. Therefore, the electronic device 100 does not cause the sliding of the rotating shaft 40 or the cover 20 to pinch the user due to the quick opening or closing of the user, thereby avoiding damage to the rotating shaft 40 or the electronic device 100 and damage of personnel caused by improper use of the user. In addition, those skilled in the art can make other changes within the spirit of the present invention. Of course, the changes made in accordance with the spirit of the present invention should be included in the scope of the present invention.
