[0002] In today's mobile communications era, mobile phones have become an indispensable tool in people's lives. With the continuous advancement of technology, mobile phones are becoming more and more powerful. As the primary interface for users to interact with their phones, the quality and performance of the mobile phone screen are crucial.

[0003] In real life, mobile phones may be subjected to pressure from various directions, such as being squeezed in a pocket, being hit when accidentally dropped, and rubbing against other items in a backpack. These pressures from different directions may have a significant impact on the performance and lifespan of the mobile phone screen. Traditional mobile phone screen pressure testing methods usually only consider pressure in a single direction and cannot fully simulate the complex stress conditions of the mobile phone in actual use. This single-direction test may lead to inaccurate assessment of the mobile phone screen's compressive performance, thereby affecting the quality and reliability of the mobile phone.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a mobile phone screen pressure testing device is provided to achieve a more practical purpose. Utility Model Content

[0025] Among them, the pressure testing mechanism includes a single-point test head 7 and a full-screen test head 8. The single-point test head 7 and the full-screen test head 8 are jointly installed with a mounting plate 6 on the opposite side. Connecting rods 5 are installed on the left and right sides of the mounting plate 6 through a rotating shaft. One end of the two sets of connecting rods 5 are both slidably connected to the side wall of the electric slide rail 3.

[0033] When the test head contacts the mobile phone screen, the pressure sensor at the contact end of the single-point test head 7 or the full-screen test head 8 and the mobile phone screen starts to monitor the pressure value in real time. The air pump 9 is controlled by the control panel to adjust the pressure of the full-screen test head 8, or the pressure of the single-point test head 7 is controlled by adjusting the pressure of the cylinder 11. The pressure value changes displayed by the pressure sensor are observed, and the status and performance of the mobile phone screen under different pressures are recorded. After the test is completed, the drive motor, air pump 9, cylinder 11, electric slide rail 3 and other components are turned off through the control panel.
