1. Technical Field
The present disclosure relates to a stress test apparatus for a hinge of an electronic device.
2. Description of Related Art
Many electronic devices such as notebook computer, mobile phones have hinges. The hinges of the electronic devices must pass a stress test before placed into practical application. However, after assembled, the components of an electronic device may not perform according to specification because of wear and tear in the production line. For example, a hinge, prior to assemble on an electronic device, passes all tests, however, after complete assemble of the electronic device, movement of the hinge may appear tighter or looser. Thus, the hinge, inter alia, of the electronic device needs to be tested before they are shipped to the consumers. Therefore there is room for improvement in the art.
Many aspects of the embodiments can be better understood with references 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 embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

In one embodiment, the rotary table 30 is rotatably installed on the console 10. The rotary table 30 rotates relative to the console 10 through a rotation motor (not shown). A coordinate axis with a central point is marked on the rotary table 30. Two pairs of L-shaped retainers 32 are located on the rotary table 30 to retain the electronic device 100 in position during testing. Each pair of retainers 32 are movably mounted to the rotary table 30.

The lifting pole 20 is located substantially perpendicular to the rotary table 30. A driven gear 27 is located at a lower portion of the lifting pole 20 to engage with the driving gear 27. Thus, a rotation about a horizontal axis of the operating pole 24 results in a rotation about a vertical axis of the lifting pole 20 through engagement of the driving gear 25 and the driven gear 27. The lifting pole 20 has external threads. The two guiding poles 26 mount to two opposite sides of the lifting pole 20.

Each fastener 80 includes a main body 82, a locking post 83 and a pair of adjusting bars 85. The main body 82 includes a guiding portion 822 and a U-shaped clamping portion 825. The holding rod 70 can extend through the guiding portion 822. The locking post 83 can extend through the guiding portion 822 and the corresponding guiding slot 72 for adjusting a position of the main body 80 on the holding rod 70. The adjusting bars 85 are located on opposite sides of the clamping portion 825 for clamping the electronic device 100. Two gaskets 86 are positioned between the two adjusting bars 85.

Due to resistance caused by friction between the top hinge portion 1082 and the bottom hinge portion 1086, the torque sensor 60 can detect a torque value of the hinge 108. A performance of the hinge 108 of the electronic device 100 may then be received through changes of the torque value during testing.
It is also to be understood, that even though numerous characteristics and advantages have been set forth in the foregoing description of preferred embodiments, together with details of the structures and functions of the preferred 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
