請同時參照圖1至圖5,檢測時,將待測物如本實施方式中的筆記型電腦90置於該載物台30上,並將該筆記型電腦90的底座夾持於該載物台30,而將該筆記型電腦90的上蓋夾裝於該擺臂50上。按壓該控制面板14上的控制按鈕142,讓該驅動機構40的馬達組41運轉,藉由該第二同步帶45帶動該傳動軸43轉動,從而,該傳動軸43兩端的第一同步帶輪46藉由對應的第一同步帶49帶動該兩第二同步帶輪48同步轉動,進而驅動該擺臂50的兩擺桿52同步擺動。該兩配重56可讓該擺臂50更容易地轉動。同時,該角度檢測裝置70的兩第五同步帶輪74借助第三同步帶76隨對應第二同步帶輪48的樞轉軸482同步轉動,由該編碼器72記錄下該擺臂50的擺動角度,並將該擺臂50的擺動角度顯示在該控制面板14的顯示幕144上;而該限位裝置60的轉盤62隨對應第二同步帶輪48的樞轉軸482同步轉動,當該擺臂50轉到最大擺動角度的位置,由該第一感測器66探測到與該轉盤62一起轉動的感應塊64,並傳信號給該馬達組41,該馬達組41便藉由該驅動機構40驅動該擺臂50反轉。從而,該筆記型電腦90的上蓋便相對其底座開啟和閉合。在該筆記型電腦90的上蓋相對於其底座閉合的過程中,該筆記型電腦90的樞紐器所受到的扭矩便可藉由該載物台30轉換為該第二感測器82受到的壓力。由於該第二感測器82受到水平方向的力時會相對該承載件84在水平方向上移動,因此,該第二感測器82測得的力是豎直方向的。 Referring to FIG. 1 to FIG. 5 simultaneously, the object to be tested, such as the notebook computer 90 of the present embodiment, is placed on the stage 30, and the base of the notebook computer 90 is clamped to the load. The table 30 is attached to the swing arm 50 of the notebook computer 90. Pressing the control button 142 on the control panel 14 causes the motor group 41 of the driving mechanism 40 to operate, and the second timing belt 45 drives the transmission shaft 43 to rotate, so that the first timing pulley on both ends of the transmission shaft 43 The two second timing pulleys 48 are synchronously rotated by the corresponding first timing belt 49, thereby driving the two swing rods 52 of the swing arm 50 to swing synchronously. The two weights 56 allow the swing arm 50 to rotate more easily. At the same time, the two fifth timing pulleys 74 of the angle detecting device 70 are synchronously rotated by the third timing belt 76 with the pivot axis 482 of the corresponding second timing pulley 48, and the swing angle of the swing arm 50 is recorded by the encoder 72. And the swing angle of the swing arm 50 is displayed on the display screen 144 of the control panel 14; and the turntable 62 of the limiting device 60 rotates synchronously with the pivot axis 482 corresponding to the second timing pulley 48, when the swing arm When the switch 50 is turned to the position of the maximum swing angle, the first sensor 66 detects the sensing block 64 that rotates together with the turntable 62, and transmits a signal to the motor group 41. The motor unit 41 is driven by the drive mechanism 40. The swing arm 50 is driven to reverse. Thus, the upper cover of the notebook computer 90 is opened and closed with respect to its base. During the closing of the upper cover of the notebook computer 90 relative to the base thereof, the torque received by the hinge of the notebook computer 90 can be converted into the pressure of the second sensor 82 by the stage 30. . Since the second sensor 82 is horizontally moved relative to the carrier 84 when subjected to a horizontal force, the force measured by the second sensor 82 is vertical.
讓該第二感測器82分別測得在該筆記型電腦90的上蓋受外力而相對其底座轉動時該載物台30向該第二感測器82施加的壓力和在該 筆記型電腦90的上蓋相對於其底座呈垂直狀態且不受外力時該載物台30向該第二感測器82施加的壓力,再藉由測量得出該第二感測器82的受力點與該載物台30的兩樞接部32的樞轉中心線之間的垂直距離,讓該兩壓力之差乘以該垂直距離即可計算出該筆記型電腦90的樞紐器的扭矩。由於該驅動機構40的雙側驅動方式不僅能保證該兩擺桿52平穩運動,更能確保該兩擺桿52分別與該載物台30的夾角一致,讓該擺臂50均勻地向該筆記型電腦90的上蓋施力,所以,檢測出的樞紐器的扭矩更精確。 The second sensor 82 is respectively configured to measure the pressure applied by the stage 30 to the second sensor 82 when the upper cover of the notebook computer 90 is rotated by an external force relative to the base thereof. When the upper cover of the notebook computer 90 is in a vertical state with respect to the base thereof and is not subjected to an external force, the pressure exerted by the stage 30 on the second sensor 82 is measured, and the second sensor 82 is received by measurement. The vertical distance between the force point and the pivot center line of the two pivoting portions 32 of the stage 30, and the difference between the two pressures is multiplied by the vertical distance to calculate the torque of the hinge of the notebook computer 90. . The two-side driving mode of the driving mechanism 40 not only ensures the smooth movement of the two swinging rods 52, but also ensures that the angles of the two swinging rods 52 respectively coincide with the loading stage 30, so that the swinging arm 50 evenly points to the note. The upper cover of the computer 90 is biased, so that the detected torque of the hinge is more accurate.
該扭矩檢測裝置1還可用於其他產品上樞紐器的扭矩檢測,如折疊式行動電話。 The torque detecting device 1 can also be used for torque detection of hinges on other products, such as a folding mobile phone.
其他實施方式中,可讓該第三同步帶輪42直接固定於該馬達412的中心軸上,並藉由該第二同步帶45及該第四同步帶輪44將速度傳給該傳動軸43,這樣就不需要該減速器414了。該馬達412可以是低速馬達。 In other embodiments, the third timing pulley 42 can be directly fixed to the central axis of the motor 412, and the speed is transmitted to the transmission shaft 43 by the second timing belt 45 and the fourth timing pulley 44. Thus, the speed reducer 414 is not needed. The motor 412 can be a low speed motor.
另外,也可將該馬達組41的馬達412藉由聯軸器或其他連接方式直接固連於該傳動軸43來驅動該傳動軸43,這樣就不需要該第三、第四同步帶輪42、44及該第二同步帶45了。 In addition, the motor 412 of the motor unit 41 can be directly fixed to the transmission shaft 43 by a coupling or other connection to drive the transmission shaft 43, so that the third and fourth timing pulleys 42 are not required. 44 and the second timing belt 45.
