[0002] With the continuous advancement of technology and the pursuit of diverse mobile phone screen forms, major mobile phone manufacturers are no longer limited to producing straight-screen phones. Flexible display phones are gradually emerging, with foldable screen phones being the most widely used. To ensure that foldable screen phones can withstand the test of daily use, especially the durability of the hinge and the stability of the screen under frequent bending, rigorous folding durability testing has become an indispensable step before they are released from the factory.

[0047] The flip assembly 60 includes a flip drive motor 61 installed on the bottom surface of the supporting plate 30, a torque sensor 62 coaxially connected to the rotor of the flip drive motor 61, a flip frame 63 rotatably installed on the top surface of the supporting plate 30, an encoder 64 coaxially connected to the rotation center of the flip frame 63, adapter plates 65 connected to the inner walls on opposite sides of the flip frame 63, elastic telescopic pins 66 installed on one side of each adapter plate 65, counterweights 67 installed on opposite ends of the flip frame 63 away from the adapter plate 65, and limiting grooves 68 installed on opposite ends of the top surface of the supporting plate 30; the limiting grooves 68 are used to match and accommodate the counterweights 67, effectively preventing the flip frame 63 from offset.

[0048] The adapter plate 65 downwardly connects to the second jig 52, and the inner end of the elastic retractable pin 66 is designed to extend into the insertion hole 5232, connecting the flip frame 63 to the auxiliary plate 523 and improving the connection stability between the flip frame 63 and the second jig 52. The flip drive motor 61 is upwardly connected to the flip frame 63 via a synchronous belt 69 to drive the flip frame 63 to flip, thereby driving the second jig 52 to flip, achieving the folding and unfolding of the foldable screen phone. Through repeated flipping, the folding durability of the foldable screen phone can be tested.

[0049] In this embodiment, one outer end of the elastic retractable pin 66 is used to match and engage the U-shaped alignment piece 562 to improve the alignment accuracy between the second fixture 52 and the first support plate 51 .

[0050] The above-mentioned folding screen mobile phone folding durability testing equipment has a simple structure and is easy to use. The clamping block 45 clamps one side of the folding screen mobile phone, the automatic clamping block 522 clamps the other side of the folding screen mobile phone, and the flip frame 63 flips and folds. The torque sensor 62 and the encoder 64 can accurately reflect the actual mechanical conditions that the mobile phone is subjected to, thereby improving the accuracy of the test and preventing damage to the mobile phone.
