Technical Field
[0001] This utility model relates to the field of flexible display testing technology, and in particular to a flexible display folding testing device. Background Technology
[0002] With the rapid development of technology, flexible displays, as an innovative display technology, are gradually changing the way we live and work. These displays utilize flexible electronics technology, successfully overcoming the physical limitations of traditional rigid displays by using bendable, rollable, or foldable materials, bringing users a more convenient and diverse user experience.
[0003] However, the durability and reliability of flexible displays in practical applications have always been key factors restricting their widespread adoption. To ensure that flexible displays maintain good performance and lifespan after repeated folding, rolling, or bending, the development of a specialized folding test device is particularly important. This test device can simulate the use of flexible displays under different folding, rolling, or bending conditions, thereby accurately assessing their durability and reliability.
[0004] Currently, some flexible display screen folding testing devices exist on the market, which can simulate the folding and bending process of displays to some extent. However, these existing devices still have shortcomings in simulating the complexities of daily user use. For example, they may not be able to fully replicate the different angles and forces that users might encounter during actual operation, which could lead to discrepancies between test results and real-world usage.
[0005] Therefore, we need to design a flexible display screen folding test device. Utility Model Content

[0024] Example: A flexible display screen folding test device, such as Figures 1-7As shown, the device includes a base 1, a fixed frame 2, a protective door 201, a controller 3, a support platform 4, a motor 5, a flipping plate 6, a clamping component 7, a sector gear 8, a cylinder 9, a top plate 10, a guide plate 11, a lifting frame 12, a top cover 13, a rack 14, a connecting frame 15, a wedge rod 16, a spring 17, a wedge bracket 18, a wedge rod 19, a spring 20, a baffle 21, a cooler 22, a heater 23, and a communicating vessel 24. The base 1 serves as the basic support structure for the entire testing device. The fixed frame 2 is connected to the top of the base 1, and the protective door 201 is rotatably connected to the front of the fixed frame 2 to protect the testing area and prevent damage to the flexible display screen or injury to personnel during the testing process. The controller 3 is installed on the top right side of the base 1. To the right of the fixed frame 2, a support platform 4 is connected to the front top of the base 1. Motors 5 are horizontally mounted at the center of both sides of the top of the base 1. Motors 5 are electrically connected to the controller 3. A flip plate 6 is connected between the output shafts of motors 5 to support and flip the flexible display screen, simulating a folding action. Clamping elements 7 are symmetrically arranged on the top of the flip plate 6 and the top of the support platform 4. The four clamping elements 7 are symmetrically designed on both sides, front and back. Each clamping element 7 consists of a clamping block and an elastic element, used to fix the flexible display screen and prevent slippage or displacement during testing. A sector gear 8 is also connected to the output shaft of motor 5. A cylinder 9 is vertically mounted upwards at the center of the bottom of the base 1. The cylinder 9 is electrically connected to the controller 3. The piston of the cylinder 9... A top plate 10 is connected to the rod. The top plate 10 has protrusions at both the front and rear center positions of its top. The tops of these protrusions are all sloped. The top plate 10 is located between the flip plate 6 and the support platform 4, facilitating the ejection of the tested flexible display screen. Guide plates 11 are symmetrically and vertically connected to the left and right sides of the top of the fixed frame 2. A lifting frame 12 is slidably connected between the four guide plates 11. A top cover 13 is provided on the top of the lifting frame 12, covering it and possibly used to protect or fix the flexible display screen. Connecting brackets 15 are connected to the left and right sides of the bottom of the lifting frame 12. A rack 14 is connected to the bottom of each connecting bracket 15, and the rack 14 meshes with adjacent sector gears 8. These racks are slidably connected at the symmetrical center positions of the bottom of the lifting frame 12. There are two wedge-shaped rods 16, with triangular inclined blocks at their closest ends. Symmetrical notches are provided at the bottom of the lifting frame 12 for the top protrusion of the top plate 10 to pass through. Springs 17 are connected to the sliding connection between the wedge-shaped rods 16 and the lifting frame 12, each spring 17 being sleeved on the end of the adjacent wedge-shaped rods 16. Wedge-shaped brackets 18 are connected to the far ends of the wedge-shaped rods 16, with triangular designs at their closest ends. A set of two wedge-shaped brackets 19 are symmetrically slidably connected at the bottom of the lifting frame 12, with each pair of wedge-shaped brackets 19 being symmetrically designed from left to right, and their closest ends also featuring a triangular structure.Furthermore, each wedge-shaped clamp 19 engages with the end of a nearby wedge-shaped bracket 18. A spring 20 connects each wedge-shaped clamp 19 to the triangular structure. A baffle 21 is symmetrically slidably connected to the lower part of the lifting frame 12. The ends of the two baffles 21 that are close to each other are designed with a rectangular structure. The rectangular structure of the baffle 21 is elastically connected to the interior of the lifting frame 12 via an elastic element. The baffle 21 contacts the wedge-shaped clamp 19. A cooler 22 and a heater 23 are symmetrically installed on the left side of the fixed frame 2. The controller 3 is electrically connected to the cooler 22 and the heater 23. The cooler 22 provides cold air to the test area, simulating a low-temperature environment, while the heater 23 provides hot air to the test area, simulating a high-temperature environment. A connector 24 is installed on the left side port of both the cooler 22 and the heater 23. The connector 24 is used to connect to the gas supply system.
[0025] When using the flexible display screen folding test device, the operating steps are as follows: First, rotate the protective door 201 forward to open it. Then, place the flexible display screen to be tested on the support platform 4 and the flip plate 6. Next, clamp and secure the flexible display screen using the clamping device 7. After placement, rotate the protective door 201 backward to close it. Then, start the motor 5 via the controller 3. The motor 5 will then drive the flip plate 6 to rotate clockwise, thus folding the flexible display screen. After the folding action is completed, the motor 5 will rotate in the opposite direction, driving the flip plate 6 to rotate counterclockwise, thereby resetting the flexible display screen. By repeating this action, the motor 5 performs the folding test on the flexible display screen.
[0026] After the folding test is completed, the controller 3 activates the cylinder 9, which drives the top plate 10 to move upward. When the top plate 10 moves to the bottom of the lifting frame 12, the protrusion on the top of the top plate 10 passes through the notch at the bottom of the lifting frame 12 and simultaneously contacts the wedge rod 16. Since the top of the protrusion is designed as a slope, it pushes the wedge rod 16 backward, causing the spring 17 to be compressed, and the connected wedge bracket 18 is also pushed outward. Since the contact surface between the wedge bracket 18 and the wedge rod 19 is a slope, the wedge rod 19 is pushed outward when the wedge bracket 18 is pushed outward. Initially, the wedge rod 19 is in contact with the rectangular structure in the stop frame 21, and the elastic element in the stop frame 21 is in a compressed state. When the wedge rod 19 is pushed outward, the spring 20 is compressed, causing the wedge rod 19 to no longer contact the rectangular structure in the stop frame 21. Subsequently, the retaining bracket 21 moves inward under the action of the elastic element, positioning the rectangular structure within the retaining bracket 21 below the flexible display screen, thereby supporting the placement of the flexible display screen. After placement, the piston rod of the cylinder 9 drives the top plate 10 to move downward and reset. At this point, the top plate 10 is no longer in contact with the wedge rod 16, and the wedge rod 16 also resets under the action of the spring 17. Subsequently, all the aforementioned components reset accordingly.
[0027] When the folded flexible display screen is placed into the lifting frame 12 via the top plate 10, the output shaft of the motor 5 can also drive the sector gear 8 to rotate. Since the sector gear 8 meshes with the rack 14, it will drive the connecting frame 15 and the lifting frame 12 to move up and down along the guide plate 11, thereby simulating the testing of the flexible display screen under bumpy conditions. When it is necessary to replace the flexible display screen for testing, the protective door 201 is opened again, and then a new flexible display screen is placed into the discharge port on the left side of the lifting frame 12 using a shovel. Then, the baffle 21 is pulled forward, causing it to move the rectangular structure outward, no longer supporting the flexible display screen. Then, the tested flexible display screen can be removed using the shovel.
[0028] In addition, the device is designed with a cooler 22 and a heater 23, which are connected to a gas supply system via a connector 24. During testing, the gas supply system can be turned on, and either high-temperature or low-temperature resistance testing of the flexible display screen can be selected as needed. The cooler 22 cools the gas, and the heater 23 heats the gas; this gas enters the interior of the fixed frame 2, thereby enabling high-temperature and low-temperature resistance testing.
[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
