1. Technical Field
This disclosure relates to torque testing devices, particularly to torque testing devices for testing hinges.
2. Description of Related Art
The torque value is an important parameter of a hinge of an electronic device, such as mobile phone or palm computer. Thus, the torque of the hinge must be tested in the manufacture procedure. However, the typical way to test the torque of the hinge is manually, which makes it difficult to get a precise value of the torque of the hinge.
Therefore, there is a room for improved in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary torque testing device. Moreover, in the drawings like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.

The main board 31 has a block 312 protruding therefrom, a shaft 314 mounted on the block 312, and a testing ring 316 wrapping around the shaft 314. Each sidewall 32 defines a bearing hole 322 and a bearing 324 retained in the bearing hole 322. Each supporting board 33 defines a retaining hole 332 and a revolving pole 334 retained in the retaining hole 332. Each revolving pole 334 is rotatably mounted in one of the bearings 324 so the supporting boards 33 can rotate around the revolving poles 334 relative to the sidewalls 32.
The measuring element 37 further includes two opposite protrusions 372, and the testing ring 316 is located between and spaced from the protrusions 372. One end of each transmitting plate 38 is mounted to the connecting board 24, and the other end of each transmitting plate 38 resists the rotating element 240 of the hinge 200. When the bracket 20 rotates, the transmitting plate 38 drives the rotating element 240 to rotate relative to the retaining element 220.

As the bracket 20 rotates relative to the seats 12, the transmitting plate 38 drives the rotating element 240 to rotate relative to the retaining element 220. The retaining element 220 simultaneously drives the loading board 34 and the supporting boards 33 to rotate around the revolving pole 334 relative to the sidewalls 32 so that the measuring element 37 moves toward and presses the testing ring 316, thereby the testing ring 316 applies torque to the measuring element 37 and the sensor 36 senses the torque applied to the measuring element 37, and then the sensor 36 transmits a signal to the display 50, corresponding to the torque applied to the measuring element 37, which is equal to the torque of the rotating element 240.
It is to be further understood that even though numerous characteristics and advantages of the exemplary embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the exemplary invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
