Please refer to Fig. 1, the better embodiment of torque detecting apparatus 1 of the present invention comprises support 10, is fixedly arranged on the supporting construction 20 at these support 10 tops, by this supporting construction 20 support and place these support 10 tops plummer 30, be fixedly arranged on this support 10 driving mechanism 50, be fixed in this driving mechanism 50 and drive and the swing arm 40 of reciprocally swinging and be used for the detection components 60 of dynamometry by this driving mechanism 50.
This support 10 comprises casing 12 and top board 16.This supporting construction 20 is fixed on this top board 16.These casing 12 front portions are provided with a control panel 14, on this control panel 14 some control knobs are set, to control the operation of this torque detecting apparatus 1.This top board 16 offers microscler through hole 18 in the front end away from this supporting construction 20.
This supporting construction 20 comprises that two compartment of terrains are arranged at the back up pad 22 of these top board 16 rear ends.
This plummer 30 comprises a substrate 32 and the biside plate 34 that bends in the same way from this limit, substrate 32 two opposite sides.This substrate 32 is offered a microscler hole 322 of dodging in the position to through hole 18 that should top board 16.Each side plate 34 is provided with an articulated section 36 that is hubbed at this back up pad 22 in the rear end of corresponding respective support plate 22.
This swing arm 40 comprises two cross bars 44 that are fixed on the fork 42 of this driving mechanism 50 and are connected between this two fork 42 and can move along this two fork 42 in a side of this two back up pad 22.Each fork 42 is provided with a counterweight 46 in the opposite side near corresponding back up pad 22.
This detection components 60 comprises sensor 62, sliding aiding elements 64 and the bracing frame 66 that is used for dynamometry.In the present embodiment, this sliding aiding elements 64 is a steel ball.This bracing frame 66 is convexly equipped with one and is provided with the maintaining part 68 of setting hole 682, is used for ccontaining this sliding aiding elements 64.
Please refer to Fig. 1 and Fig. 2, during assembling, one end of the sensor 62 of this detection components 60 is fixed in the lower surface of the substrate 32 of this plummer 30, and allow this sensor 62 along the bearing of trend of dodging hole 322 of this substrate 32 freely be suspended from this dodge hole 322 under.The bracing frame 66 of this detection components 60 is fixed in the lower surface of the top board 16 of this support 10, and across under the through hole 18 of this top board 16, and allow the maintaining part 68 of this bracing frame 66 be placed in this through hole 18.Set hole 682 with what this sliding aiding elements 64 placed this maintaining part 68, the other end of this sensor 62 is just movably pressed and is put this sliding aiding elements 64, in the present embodiment, contacts for putting between this sensor 62 and this ball.Thereby allow this detection components 60 place the front end of this plummer 30, and this plummer 30 is supported and leave this top board 16 upper surface certain altitudes with two back up pads 22 that place these plummer 30 rear ends.
Please continue with reference to Fig. 3 to Fig. 5, during detection, notebook computer in determinand such as the present embodiment 70 is placed on this plummer 30, and the base 72 of this notebook computer 70 is fixed in this plummer 30, and the loam cake 74 of this notebook computer 70 is clipped in this swing arm 40.Allow this driving mechanism 50 drive these swing arm 40 relative these plummer 30 reciprocally swingings, and the counterweight 46 in this swing arm 40 can allow this swing arm 40 of these driving mechanism 50 easier drives rotate, thereby, allow loam cake 74 relative its bases 72 of this notebook computer 70 open and closure.Because in the process of loam cake 74 with respect to its base 72 closures of this notebook computer 70, the moment of torsion that is connected in the pivot device between the base 72 public loam cakes 74 of this notebook computer 70 is converted to pressure that this sensor 62 is subjected to by this plummer 30 and is recorded by this sensor 62.Since when this sensor 62 is subjected to the power of horizontal direction relatively this sliding aiding elements 64 slide in the horizontal direction, therefore, the power that is recorded by this sensor 62 is vertical direction.
Allow the loam cake 74 of this notebook computer 70 turn to the state vertical with this base 72, because the weight of this notebook computer 70, this notebook computer 70 is exerted pressure to this sensor 62 by this plummer 30.Suppose that the power that is recorded by this sensor 62 is F1, and the distance between the pivot device of the application point of F1 and this notebook computer 70 is D1, and the weight of the base 72 of this notebook computer 70 is W1, distance between the center of gravity of this base 72 and this pivot device is d1, the moment of torsion of this pivot device represents that with T then the stress balance formula of this base 72 is:
T+W1*d1＝F1*D1
The weight of supposing the loam cake 74 of this notebook computer 70 is W2, distance between the center of gravity of this loam cake 74 and this pivot device is d2, and this swing arm 40 is F2 to these loam cake 74 externally applied forces, and the distance between the application point of F2 and this pivot device is D2, and then the stress balance formula of this loam cake 74 is:
T＝F2*D2+W2*d2
From the above, this loam cake 74 is with respect to this base 72 in vertical state the time, and between the center of gravity of this loam cake 74 and this pivot device is zero apart from d2, i.e. F2*D2=0, and when this loam cake 74 is not subjected to external force, F2*D2=0, thus T=0 can be got.
And when T=0, T+W1*d1=F1*D1 is reduced to:
W1*d1＝F1*D1 (1)
In addition, suppose that loam cake 74 when this notebook computer 70 is subjected to external force F2 and its base 72 rotatable covers are fashionable relatively, the power that is recorded by this sensor 62 is F1 ', and then the stress balance formula of this base 72 is:
T+W1*d1＝F1’*D1 (2)
Deduct (1) formula with (2) formula, just have:
T＝(F1’-F1)*D1＝ΔF*D1
Wherein, Δ F=F1 '-F1.Because D1 is certain value, make zero after can allowing this sensor 62 record F 1 during detection.Like this, when this loam cake 74 was subjected to external force and rotates, these sensor 62 measured power (Δ F) multiply by the torque T that arm of force D1 can directly calculate this pivot device.
This torque detecting apparatus 1 also can be used for the detection of the moment of torsion of pivot device on other products, as clamshell phone.
In other embodiments, can the backing plate 38 (as shown in Figure 1) of these plummer 30 upper and lower translations relatively be set at this plummer 30, when the pivot center line of the center line of the pivot device of notebook computer to be measured and this swing arm 40 is not in same surface level, can allow their both centerline in same surface level by adjusting this backing plate 38 up and down.
This sliding aiding elements 64 also can be a roller.Be about to this roller and be supported in pivotally on this bracing frame 66, and contact with these sensor 62 lines.
In addition,, cause the measurement out of true, can set firmly a harder cushion block 69, allow this cushion block 69 directly contact with this sliding aiding elements 64 in the other end bottom of this sensor 62 for the sensor 62 long-time backs of avoiding contacting with this sliding aiding elements 64 of using form depression.
The bracing frame 66 of this detection components 60 also can be fixed in the upper surface of this top board 16.At this moment, promptly need on this top board 16, not offer through hole 18.
