Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a fatigue testing device for curved screens. Background Technology
[0002] A curved screen is a screen form that has a unique curvature compared to a traditional flat screen. This design brings many advantages. The curved design can fit the visual physiological structure of the human eye, allowing the viewer's field of vision to be better enveloped by the screen, reducing visual distortion at the edges of the screen. When watching movies or playing games, users can more easily immerse themselves in the experience and have a lifelike feeling.
[0003] Curved screen testing is a crucial step in ensuring its performance and quality. This involves applying a certain amount of external force to the curved screen over a prolonged period to simulate everyday use, observing whether the screen's curvature changes. A high-quality curved screen should maintain a constant curvature under normal external force, without deformation that would affect the display quality. Curved screen testing typically requires manual operation, but this is inefficient, repetitive, and can lead to worker negligence and improper procedures. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a fatigue testing device for curved screens, which aims to improve the low efficiency of manual operation, as well as the fact that repetitive work may lead to worker slackness and improper operation.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A fatigue testing device for an arc screen includes a main frame. A motor rotating mechanism is fixedly connected to the connection point of the main frame. A motor is fixedly connected to the upper surface of the motor rotating mechanism. The output end of the motor passes through the interior of the motor rotating mechanism and is fixedly connected to a connecting rod. A push rod is rotatably connected to the connection point of the connecting rod. A swing frame is provided at the connection point of the push rod. Vertical beam structures are provided inside both sides of the swing frame. A flexible screen is fixedly connected to the connection point of the vertical beam structures.
[0007] Preferably, the main frame is internally rotatably connected to a rotating shaft.
[0008] Preferably, the lower surface of the rotating shaft is fixedly connected to the upper surface of the swing frame.
[0009] Preferably, the connection points of the main frame are fixedly connected to a fixing bracket.
[0010] Preferably, the central connection point of the flexible screen is fixedly connected to the connection point of the fixed frame.
[0011] This utility model has the following beneficial effects:
[0012] 1. In this utility model, the starting motor drives the connecting rod to rotate, the connecting rod pushes the swing frame to swing through the push rod, and the swing frame drives the flexible screen to rotate through the vertical beam structure. At the same time, the fixed frame restricts the middle connection point of the flexible screen, which can realize automatic bending of the flexible screen, improve the efficiency of the inspection work, save manpower and avoid the problem of non-standard manual operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Reference Figures 1-3 An embodiment of this utility model provides a fatigue testing device for an arc screen, comprising a main frame 1, a motor rotating mechanism 2 fixedly connected to the connection point of the main frame 1, a motor 3 fixedly connected to the upper surface of the motor rotating mechanism 2, the output end of the motor 3 passing through the interior of the motor rotating mechanism 2 and fixedly connected to a connecting rod 4, a push rod 5 rotatably connected to the connection point of the connecting rod 4, a swing frame 6 provided at the connection point of the push rod 5, vertical beam structures 10 provided inside both sides of the swing frame 6, and a flexible screen 7 fixedly connected to the connection point of the vertical beam structure 10.
[0020] Specifically, the motor rotation mechanism 2 fixes the motor 3, the motor 3 drives the connecting rod 4 at the output end to rotate, the connecting rod 4 drives the push rod 5 to rotate, the push rod 5 pushes the swing frame 6 to swing, the left and right connection points of the flexible screen 7 are connected by the vertical beam structure 10, the vertical beam structure 10 fixes the flexible screen 7 from the top and bottom, and the connection points on both sides of the flexible screen 7 swing with the swing frame 6.
[0021] Reference Figures 1-3 The main frame 1 is internally connected to a rotating shaft 9. The lower surface of the rotating shaft 9 is fixedly connected to the upper surface of the swing frame 6. The connection point of the main frame 1 is fixedly connected to a fixing frame 8. The middle connection point of the flexible screen 7 is fixedly connected to the connection point of the fixing frame 8.
[0022] Specifically, the pivot 9 supports the rotation of the swing frame 6, the swing frame 6 rotates around the pivot 9, and when the swing frame 6 drives the flexible screen 7 to rotate, the middle part of the flexible screen 7 is restricted by the fixing frame 8.
[0023] Working principle: When using this device, the flexible screen 7 and the swing frame 6 are fixedly connected by the vertical beam structure 10. The swing frame 6 is connected to the two connection points on both sides of the flexible screen 7, while the fixing frame 8 fixes the middle connection point of the flexible screen 7. When the starting motor 3 drives the connecting rod 4 to rotate, the connecting rod 4 pushes the swing frame 6 to swing back and forth through the push rod 5. The swing frame 6 drives the flexible screen 7 to swing. With the restriction of the fixing frame 8, the flexible screen 7 can be repeatedly bent. This verifies how many times the flexible screen 7 will be bent during the process of repeatedly adjusting the curved surface shape, and how many times it will cause the display surface to be abnormal. It also tests the stability of the product under repeated bending. This device can realize automatic bending of the flexible screen 7, improve work efficiency, and save manpower.
