Description

Technical Field

[0001] This utility model relates to the field of mobile phone testing technology, and in particular to a mobile phone screen sensitivity testing device. Background Technology

[0002] The mobile phone screen sensitivity testing device is a professional device used to test the response performance of mobile phone touch screens. Its core function is to simulate user operation and accurately test key indicators such as screen touch accuracy, response speed, and touch dead zone. It simulates touch scenarios with different force and speed and is widely used in mobile phone R&D, production quality inspection and other processes to ensure that the screen touch experience meets the standards.

[0003] Existing mobile phone screen sensitivity testing devices mostly limit touch control methods to the vertical direction, only enabling clicks or swipes perpendicular to the screen surface. However, in actual use, users often hold the phone at a 15°-45° angle and touch the screen, and there are also scenarios where fingertips lightly rub the screen edge. This disconnect from real-world usage causes the sensitivity test data for the screen edge area to deviate from actual usage, failing to accurately reflect the true response performance of this area under common user operations. This results in distorted test results and makes it difficult to effectively guide product optimization. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 4 As shown, this application provides a mobile phone screen sensitivity testing device, including: a position adjustment device, including a test base frame 1, two sets of threaded rods 3 movably sleeved inside the test base frame 1, a connecting block 4 threaded to the outer wall of the threaded rods 3, a connecting slide rod 13 fixedly connected to the side of the connecting block 14, a connecting block 14 movably sleeved to the outer wall of the two sets of connecting slide rods 13, a rotating sleeve 19 fixedly connected to the top of the connecting block 14, a rotating sleeve 15 movably sleeved inside the rotating sleeve 19, and a placement platform 6 fixedly connected to the top of the rotating sleeve 15, for moving the mobile phone screen to any position at the bottom of the test pen tip 16.

[0028] After adopting the above technical solution, the test base frame 1 serves as the basic frame, providing installation support for other components. The setting of two sets of threaded rods 3 allows the connecting block 1 4 to move on the threaded rods 3, thereby driving the connecting slide rod 2 13 to move. Ultimately, the connecting block 2 14 and the placement platform 6 connected to it can move in a plane within the test base frame 1, thus accurately moving the mobile phone screen on the placement platform 6 to any position at the bottom of the test pen tip 16. This realizes the function of testing different positions of the mobile phone screen, and has strong flexibility and accuracy.

[0029] In one optional embodiment, the output end of motor 2 is fixedly connected to the side of threaded rod 3, and the outer wall of motor 2 is fixedly connected to test base frame 1.

[0030] Motor 2 serves as the power source. When motor 2 starts, its output end drives the threaded rod 3 to rotate. The threaded rod 3 is threadedly connected to the connecting block 4. According to the principle of threaded transmission, the connecting block 4 will move linearly along the thread direction on the threaded rod 3. This achieves precise control of the movement of the connecting block 4 through the drive of motor 2, thereby providing power support for the entire position adjustment device and making the movement of the placement platform 6 more stable and controllable.

[0031] In one optional embodiment, the two sets of threaded rods 3 are arranged in a horizontal and vertical manner, the two sets of connecting slide rods 13 are arranged in a high and low manner, and the connecting block 14 is located at the intersection of the two sets of connecting slide rods 13.

[0032] Two sets of threaded rods 3, one horizontal and one vertical, can adjust the position of connecting block 1 4 in two horizontal dimensions, allowing connecting block 2 14 to move to any position within the plane of the test base frame 1. The two sets of connecting slide rods 2 13 are set at different heights, with connecting block 2 14 located at the intersection. This structural design makes connecting block 2 14 more stable during movement, avoiding shaking or jamming, ensuring that the placement platform 6 can smoothly move the mobile phone screen to the designated position, and improving the accuracy and reliability of the test.

[0033] In an optional implementation, multiple sets of connecting slide rods 5 are fixedly connected inside the test base frame 1, and the outer wall of the connecting slide rods 5 is movably sleeved with one set of connecting blocks 4.

[0034] The function of connecting slide bar 5 is to provide guidance and support for connecting block 4. When connecting block 4 moves under the drive of threaded rod 3, connecting slide bar 5 can restrict the direction of movement of connecting block 4, so that it can only move along the axis of connecting slide bar 5, thereby ensuring the linearity and stability of the movement of connecting block 4. At the same time, the setting of multiple sets of connecting slide bars 5 also increases the support points of connecting block 4, improves the structural strength and stability of the entire device, and can better bear the weight of the placement platform 6 and the mobile phone screen.

[0035] In an optional embodiment, an extension frame 7 is fixedly connected to the top of the test base frame 1, and a connecting collar 11 is fixedly connected to the extended end of the extension frame 7. A connecting ring 12 is movably sleeved inside the connecting collar 11, and the connecting ring 12 is spherical.

[0036] The function of the extension frame 7 is to extend the connecting collar 11 to a suitable position above the test base frame 1 so that components such as the test pen tip 16 can perform touch detection on the mobile phone screen. The cooperation between the connecting collar 11 and the spherical connecting ring 12 allows the connecting ring 12 to rotate freely at multiple angles within the connecting collar 11. This structural design provides the test pen tip 16 with a flexible angle adjustment function, which can adapt to the testing needs of different angles, thereby enabling a more comprehensive detection of the sensitivity of the mobile phone screen.

[0037] In an optional embodiment, a guide pen 24 is fixedly connected to the bottom end of the connecting ring 12, a limiting guide rod 18 is movably sleeved inside the guide pen 24, a test pen tip 16 is fixedly connected to the bottom end of the limiting guide rod 18, and a spring 17 is fixedly connected to the top end of the test pen tip 16.

[0038] The connecting ring 12 drives the guide pen rod 24 to rotate, thereby adjusting the angle of the test pen tip 16. The limiting guide rod 18 is movably sleeved within the guide pen rod 24. On the one hand, it guides the test pen tip 16, ensuring that the test pen tip 16 moves in a straight line when moving up and down. On the other hand, it also limits the range of movement of the test pen tip 16. The spring 17 provides a certain elastic force to the test pen tip 16. When the test pen tip 16 contacts the mobile phone screen, the spring 17 can act as a buffer to prevent the test pen tip 16 from causing excessive pressure on the mobile phone screen. At the same time, it can also ensure that the test pen tip 16 and the mobile phone screen maintain a certain contact pressure to ensure the accuracy of the test.

[0039] In one optional embodiment, a toothed ring 10 is fixedly connected to the outer wall of the guide pen 24. The toothed ring 10 is semi-circular and has several sets of teeth fixedly connected to its outer wall.

[0040] The gear ring 10 meshes with the gear 9. When the motor 8 drives the gear 9 to rotate, the gear 9 will drive the gear ring 10 to rotate, thereby causing the guide pen rod 24 to rotate around the axis of the connecting ring 12, realizing the angle adjustment of the test pen tip 16. The semi-circular gear ring 10 can adjust the angle of the test pen tip 16 within a certain range to meet the needs of different test angles. This structural design is simple and easy to implement, and also has high precision and stability.

[0041] In one optional embodiment, a second motor 8 is fixedly connected to the outer wall of the extension frame 7, and a first gear 9 is fixedly connected to the output end of the second motor 8. The outer wall of the first gear 9 meshes with the gear ring 10.

[0042] Motor 28 serves as the power source for angle adjustment. When motor 28 starts, its output drives gear 19 to rotate. Gear 19 meshes with gear ring 10. According to the gear transmission principle, gear ring 10 rotates along with gear 19, thereby driving guide pen rod 24 and test pen tip 16 to rotate, achieving precise control of the angle of test pen tip 16. This method of using motor 28 and gear transmission provides stable power output, ensuring more accurate and reliable angle adjustment of test pen tip 16.

[0043] In one optional embodiment, a plurality of transmission gear blocks 20 are fixedly connected to the bottom end of the placement platform 6. The plurality of transmission gear blocks 20 are arranged in a circular array with the rotating sleeve block 2 19 as the center. The bottom end of the transmission gear blocks 20 is meshed with a gear 23. The output end of the motor 3 21 is fixedly connected to the side of the gear 23. A support frame 22 is fixedly connected to the outer wall of the motor 3 21. The side of the support frame 22 is fixedly connected to the connecting block 2 14.

[0044] When motor 3 21 starts, its output drives gear 2 23 to rotate. Gear 2 23 meshes with transmission gear block 20. Since transmission gear block 20 is arranged in a circular array with rotating sleeve block 2 19 as the center, when gear 2 23 rotates, it drives transmission gear block 20 to rotate around the axis of rotating sleeve block 2 19, thereby causing the placement platform 6 to rotate on the top of rotating sleeve block 2 19. This structural design allows the mobile phone screen to rotate horizontally, enabling touch contact detection of the mobile phone screen from different angles, further improving the comprehensiveness and accuracy of the test.
