Description

Technical Field

[0001] This utility model belongs to the field of mobile phone display testing, specifically relating to a protective cover for testing the fatigue life of mobile phone screens. Background Technology

[0002] Mobile phone screen fatigue life testing primarily simulates daily user scenarios to assess the screen's durability and lifespan under prolonged use. Tests include changes in screen brightness, contrast, and color accuracy, as well as assessing for signs of burn-in or aging. During testing, the phone screen is connected to the test power supply via wires. Multiple screens are typically tested simultaneously, placed on the same frame. Due to the lack of effective securing mechanisms for multiple screens, stability is difficult when the frame is moved. If screen movement during transport causes wires to detach or become loose, test failures or inaccurate data can result. Utility Model Content

[0003] To address the aforementioned problems and technical requirements, this utility model provides a protective cover for testing the fatigue life of mobile phone screens. It can accommodate multiple test screens, provides stable fixation for the test screens, and facilitates the overall transport of the frame during testing.

[0004] The technical solution of this utility model is as follows: a protective cover for testing the fatigue life of a mobile phone screen, including a side plate, a base plate, an end plate, and a test screen workpiece. Multiple workpiece slots are arranged parallel to each other on the base plate. A test screen workpiece is vertically inserted into each workpiece slot. The workpiece slot is a through groove penetrating the front and rear ends of the base plate. Side plates are symmetrically connected to both sides of the base plate. The inner sides of the upper part of the side plates are connected via end plates. Two end plates are correspondingly arranged above the same base plate. Multiple vertical limiting grooves are correspondingly arranged on the inner sides of the two end plates. The vertical limiting grooves correspond one-to-one with the workpiece slots on the base plate. The test screen workpiece is placed horizontally into the workpiece slot. The front straight edge and rear straight edge of the test screen workpiece are respectively inserted into the vertical limiting grooves of the two end plates. The workpiece slot and the two vertical limiting grooves together limit the position of the test screen workpiece. The limiting width between the two end plates is adjustable. The end plates and side plates are detachably connected.

[0005] Furthermore, the surface of the test screen workpiece is provided with a conductive sheet. The lower section of the conductive sheet is horizontally folded. The horizontal section of the conductive sheet extends outward along the workpiece slot to the outside of the base plate. The end of the horizontal section is bent vertically downward to the space below the base plate. The bottom end of the conductive sheet is connected to an external power source.

[0006] Furthermore, the end plate is only connected to the upper half of the side plate, and there is an unobstructed channel between the bottom surface of the end plate and the bottom plate, with the conductive sheet extending outward and downward from the unobstructed channel.

[0007] Furthermore, the test screen workpiece can be placed in the workpiece slot in either the forward or reverse orientation. When the test screen workpiece is placed in the forward orientation, the conductive sheet extends from the unobstructed channel of the front end plate. When the test screen workpiece is placed in the reverse orientation, the conductive sheet extends from the unobstructed channel of the rear end plate.

[0008] Furthermore, the upper part of the side plate is provided with multiple sets of horizontal elongated holes. Each set consists of two horizontal elongated holes arranged parallel to each other vertically. The two horizontal elongated holes connect the upper and lower parts of the end plate end face. The end plate end face and the horizontal elongated holes are locked together by screws. The end plate can slide left and right along the horizontal elongated holes for adjustment. The horizontal elongated holes allow for free adjustment of the spacing between a set of end plates, accommodating test screen workpieces of multiple sizes.

[0009] Furthermore, the base plate and the side plates are fixedly connected by screws.

[0010] Furthermore, multiple base plates are connected along the length between the two side plates, with a distance between adjacent base plates. Each base plate and the two end plates above it form a testing chamber. Each testing chamber contains multiple test screen workpieces. Cover plates are fixedly connected to the top of the two side plates, and the cover plates close the top of all testing chambers.

[0011] Furthermore, two opposing connecting plates are provided below the side plate. The middle sections of the two connecting plates are respectively connected to the bottom surfaces of different base plates, and the two ends of the connecting plates extend to both sides of the side plate. Screw holes are machined at both ends of the connecting plates. The connecting plates are used to connect to the external frame structure and fix the protective cover structure to the frame.

[0012] Furthermore, the base plate, end plate, and connecting plate are all made of aluminum alloy sheet, and the exterior of the aluminum alloy sheet is coated with an anti-static layer. The lightweight aluminum alloy material enables the overall structure of the protective cover to be lightweight.

[0013] Furthermore, the cover plate and two side plates are all made of anti-static acrylic sheets. The transparent side plates and cover plate allow for observation of the internal testing process, enabling timely detection of defective products.

[0014] The beneficial effects of this utility model are:

[0015] 1) The testing chamber, composed of a base plate, side plates, and end plates, ensures the vertical fixation of the test screen workpiece. The bottom and side edges of the workpiece are embedded in workpiece slots and vertical limiting slots, respectively, maintaining good stability. Even if the entire protective cover shakes during transport, it will not tip over or collide, exhibiting high testing stability. 2) Multiple testing chambers can be set along the length between the two side plates. The test screen workpieces in each chamber are vertically inserted, saving storage space and accommodating more workpieces, improving testing efficiency and saving testing costs. 3) The conductive sheet of the test screen workpiece can extend downwards from two unobstructed channels at the front and rear, allowing for free setting of the workpiece's placement direction and increasing testing flexibility. The accommodating distance between the two end plates can be freely adjusted via horizontal elongated holes, accommodating workpieces of more sizes and enhancing applicability. 4) The protective cover structure, combining aluminum and acrylic, combines lightweight design with observability, reducing transport weight and allowing testers to observe the testing process from the outside.
