1. Technical Field
This disclosure relates to hinge durability testing devices, particularly to a hinge durability testing device for testing a hinges lifespan.
2. Description of Related Art
Some electronic devices are flip type devices, which include a cover, a main body and a hinge rotatably coupling the cover and the main body. The hinge is used to open and close the cover relative to the main body, so the durability of the hinge is an important parameter of the electronic device. Thus, the durability of the hinge must be tested in the manufacture procedure. To test the durability of the hinge, a test device is used. The test device typically includes a cover holder used to hold the cover and a main body holder used to hold the main body. The cover holder rotates relative to the main body holder causing the cover to open and close relative to the main body, as a result, the durability of the hinge is tested. However, typical test device cannot steadily hold the cover, which makes it difficult to get a precise value of the durability 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 hinge durability 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 chassis 10 includes a platform 11, on which the cover holder 20 and the main body holder 30 are mounted. The chassis 10 further includes a control panel 13, e.g., a touch panel, controlling the openings and closings of the cover holder 20 relative to the main body holder 30.

The connecting rod 21 has a plurality of unthreaded mounting holes 211 defined near the two ends. Each screw 25 is located and can move longitudinally in one of the unthreaded mounting holes 211. Each connecting element 22 includes a first connecting portion 221 and a second connecting portion 223 protruding from the first connecting portion 221. The first connecting portion 221 defines a plurality of threaded holes 2211. One screw 25 is screwed in each hole 2211, to retain the connecting rod 21 on the connecting elements 22. When the screws 25 are loosened, the connecting elements 22 can move longitudinally relative to the connecting rod 21 as the screws 25 move in their corresponding unthreaded mounting holes 211. Each second connecting portion 223 defines a plurality of retaining holes 2231, each of which holds one of the locking elements 24.
Each support rod 23 includes a first surface 231 facing the other support rod 23, and a second surface 233 adjacent to the first surface 231. Each support rod 23 has a first sliding groove 2311 defined in the first surface 231, in which one of the second connecting portions 223 is slidably located. Each support rod 23 defines a second sliding groove 2331 in the second surface 233 and perpendicular and communicating with a corresponding first sliding groove 2311. The locking elements 24 are slidably located in the second sliding grooves 2331. In this exemplary embodiment, the locking elements 24 are screws. One end of each locking element 24 is screwed in one of the retaining holes 2231, the other end is bigger than the second sliding grooves 2331 to prevent the support rods 23 from separation from the connecting rod 21. To adjust the position between the connecting rod 21 and the support rods 23, the connecting elements 22 slide in the first sliding grooves 2311 and the locking elements 24 slide in the second sliding grooves 2331. In addition, because the locking elements 24 slide in the second sliding grooves 2331, the connecting rod will not incline when sliding relative to the support rods 23.

The main body holder 30 includes a base 31 mounted on the platform 11, two sidewalls 33 located at opposite sides of the base 31, a plurality of securing plates 35 protruding from the sidewall above the base 31, a plurality of screws 37 equal in number to the number of securing plates 35. The base 31 is used to support the main body 230. In this exemplary embodiment, each sidewall 33 has two securing plates 35. The main body 230 is located between the securing plates 35 and the base 31, and secured by the screws 37 so the main body 230 is held on the main body holder 30.
To test the hinge of the electronic device 200, the cover 210 is held by the holding elements 26 the main body 230 is secured between the base 31 and the securing plates 35. Then, the driving mechanisms 40 drive the cover holder 20 to open and close relative to the main body holder 30 so the cover 210 opens and closes relative to the main body 230 until a predetermined durability of the hinge 220 is reached. Additionally, the locking elements 24 can be loosened and then the connecting rod 21 slides relative the support rods 23 to adjust the cover holder 20, to test another electronic device 200 which has a different size from the first electronic device 200.
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.
