Description

Technical Field

[0001] This utility model relates to the field of flexible screen protection technology, and in particular to a flexible screen protection structure. Background Technology

[0002] With the rapid growth of users of foldable screen electronic products, the issue of screen protection has become increasingly prominent. Unlike traditional rigid screens, flexible screens are made of soft materials, which have weaker impact and scratch resistance. They are easily scratched or even structurally damaged due to accidental collisions, squeezing, or friction. At the same time, due to high manufacturing costs, repair costs are also significantly higher than those of ordinary screens. Traditional hard protective films are also difficult to apply to flexible surfaces. This contradiction has become a major pain point for the flexible screen electronic product industry.

[0003] In traditional electronic products, flexible screens are usually covered with flexible protective films to reduce daily wear and tear. However, this type of soft protective structure has certain limitations: when hard particles enter between the screens during the folding process, the impurities may squeeze the screen in certain areas as the device is bent, causing problems such as pressure marks, cracks, or even leakage, which seriously affect the display function and lifespan. Utility Model Content

[0004] This invention provides a flexible screen protection structure to solve the problem that when hard particles enter between the screen and the protective film during the folding process, the impurities may squeeze the screen locally as the bending action progresses, causing damage, cracking, or even leakage to the flexible screen, which seriously affects the display function and service life.

[0005] This utility model provides a flexible screen protection structure, specifically including: an outer frame, the outer frame being composed of two "U"-shaped protective frames hinged together by two frame hinges, the inner surfaces of the protective frames and frame hinges being provided with arc-shaped grooves, the inner surface of the protective frame having an inner sliding groove, the upper part of the inner sliding groove having an identifier sliding groove, an opening / closing sensor being embedded and fixedly connected to the upper surface of the end of the protective frame, a particle infrared identifier being slidably connected inside the identifier sliding groove, an identifier slider being fixedly connected below the particle infrared identifier, the identifier slider being slidably connected to the inner sliding groove, a limit push rod being slidably connected inside the inner sliding groove, the limit push rod being located below the identifier slider, an electromagnetic push cylinder being fixedly connected inside the protective frame, the push rod of the electromagnetic push cylinder being fixedly connected to the limit push rod, a mobile power supply and a data processor being fixedly connected inside the protective frame, the mobile power supply and the data processor being connected to the opening / closing sensor, the particle infrared identifier and the electromagnetic push cylinder via an electrical connection wire.

[0006] Furthermore, two sliding groove magnetic blocks are fixedly connected to the upper surface of the inner sliding groove of the frame, and two slider reset magnetic blocks are fixedly connected to the upper surface of the identifier slider, and the sliding groove magnetic blocks and the slider reset magnetic blocks are magnetically connected.

[0007] Furthermore, the lower surface of the identifier slider is provided with three trapezoidal groove structure slider insertion ports.

[0008] Furthermore, three trapezoidal push rod top blocks are fixedly connected to the upper surface of the limiting push rod, and the contour structure of the push rod top blocks is consistent with the contour of the slider insertion port.

[0009] Furthermore, a cylinder pusher cover plate is fixedly connected to the bottom end of the protective frame, and the electromagnetic cylinder is fixedly connected above the cylinder pusher cover plate.

[0010] Furthermore, the protective frame has an outer cavity inside, and the power supply and data processor are fixedly installed inside the outer cavity.

[0011] This utility model provides a flexible screen protection structure, which has the following beneficial effects: The flexible screen protection structure in this utility model is a frame-type protection structure, which is fixedly installed on the outer periphery of the flexible screen product. During the folding process of the flexible screen product, as the flexible screen folds, the two protective frames overlap with the product. During this process, the folding action is detected by the opening and closing sensor, and the particle infrared detector is activated. The particle infrared detector can detect whether there are particles on the outer surface of the flexible screen. If particles or other impurities are present, the electromagnetic push cylinder is triggered to push the limit push rod, so that the push rod top block and the slider insertion port are intersected. The push rod top block and the lower surface of the detector slider are attached, preventing the particle infrared detector from retracting and hindering the attachment of the two protective frames. This prevents the product from folding, thereby avoiding the problem of impurities squeezing the screen and causing damage, cracking, or even leakage to the flexible screen.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please refer to Figures 1 to 9 : This utility model proposes a flexible screen protection structure, including: an outer frame, which is composed of two "U"-shaped protective frames 1 hinged together by two frame hinges 2. Both the inner surfaces of the protective frames 1 and the frame hinges 2 are provided with arc-shaped grooves. An inner sliding groove 101 is formed inside the protective frame 1, and an identifier sliding groove 103 is formed above the inner sliding groove 101. An opening / closing sensing sensor 3 is embedded and fixedly connected to the upper surface of the end of the protective frame 1. A particle infrared identifier 4 is slidably connected inside the identifier sliding groove 103. An identifier slider 401 is fixedly connected below the particle infrared identifier 4. 1. A sliding groove 101 is connected inside the sliding frame. A limiting push rod 6 is slidably connected inside the sliding groove 101. The limiting push rod 6 is located below the recognizer slider 401. An electromagnetic push cylinder 5 is fixedly connected inside the protective frame 1. The push rod of the electromagnetic push cylinder 5 is fixedly connected to the limiting push rod 6. The folding action of the outer frame can be detected by the opening and closing sensor 3. When the flexible screen product is folded, as the two protective frames 1 flip and stick together, the opening and closing sensor 3 detects that the opposite protective frame 1 is close, thereby determining that the flexible screen product has been folded. The standby particle infrared recognizer 4 can then be activated to detect the surface of the flexible screen.

[0018] In this embodiment, a mobile power supply 7 and a data processor 8 are fixedly connected inside the protective frame 1. The mobile power supply 7 and the data processor 8 are connected to the opening / closing sensor 3, the particle infrared detector 4, and the electromagnetic push cylinder 5 via electrical connection lines. The mobile power supply 7 stores the electrical energy required for the operation of the opening / closing sensor 3, the particle infrared detector 4, and the electromagnetic push cylinder 5. The mobile power supply 7 has an external charging port for charging. The data processor 8 processes the detection signals from the opening / closing sensor 3 and the particle infrared detector 4 and controls the movement of the electromagnetic push cylinder 5 to adjust the position of the limit push rod 6, so that the protective structure has two states.

[0019] In this embodiment, two sliding magnetic blocks 102 are fixedly connected to the upper surface of the sliding groove 101 inside the frame, and two slider reset magnetic blocks 403 are fixedly connected to the upper surface of the identifier slider 401. The sliding magnetic blocks 102 and the slider reset magnetic blocks 403 are magnetically connected. Under normal conditions, the identifier slider 401 is pulled outward by the magnetic connection between the sliding magnetic blocks 102 and the slider reset magnetic blocks 403, so that the particle infrared identifier 4 protrudes from the surface of the protective frame 1, and the infrared detection position of the particle infrared identifier 4 is flush with the outer surface of the flexible screen, thereby improving the detection accuracy.

[0020] In this embodiment, the lower surface of the identifier slider 401 has three trapezoidal groove structure slider slots 402; the upper surface of the limiting push rod 6 is fixedly connected to three trapezoidal structure push rod top blocks 601, the contour structure of the push rod top blocks 601 is consistent with the contour of the slider slots 402; under normal conditions, when the particle infrared identifier 4 is in standby mode or when the surface of the flexible screen is free of impurities, the electromagnetic push cylinder 5 controls the position of the limiting push rod 6, so that the slider slots 402 are aligned with the push rod top blocks 601, and as the product is folded, the particle infrared identifier 4 is... When the particle infrared detector 4 is squeezed, it can retract into the protective frame 1. When the particle infrared detector 4 detects impurities on the surface of the flexible screen, the electromagnetic push cylinder 5 controls the position of the limit push rod 6, so that the slider insertion port 402 and the push rod top block 601 are intersected. As the product is folded, the particle infrared detector 4 is squeezed. Due to the contact between the push rod top block 601 and the detector slider 401, the particle infrared detector 4 cannot retract, so the product cannot be folded. This avoids impurities squeezing the screen locally, which may cause the flexible screen to be damaged, cracked, or even leak.

[0021] In Example 2, based on Example 1, a cylinder pusher cover plate 104 is fixedly connected to the bottom end of the protective frame 1, and an electromagnetic cylinder 5 is fixedly connected above the cylinder pusher cover plate 104. The cylinder pusher cover plate 104 covers the installation space of the electromagnetic cylinder 5, improving the sealing performance and facilitating the maintenance and replacement of the electromagnetic cylinder 5. An outer frame cavity 105 is opened inside the frame rod of the protective frame 1, and the mobile power supply 7 and the data processor 8 are fixedly installed inside the outer frame cavity 105. The installation of the mobile power supply 7 and the data processor 8 through the outer frame cavity 105 improves the space utilization rate.

[0022] The working principle of this embodiment is as follows: When the foldable electronic product equipped with a flexible screen is unfolded, the particle infrared detector 4 is in standby mode. During the folding process of the electronic product, the opening and closing sensing sensor 3 detects the distance between the two protective frames 1. If the distance between the two protective frames 1 decreases, it can be determined that the electronic product is folding, and an activation signal is sent to the data processor 8 to turn on the particle infrared detector 4. If the particle infrared detector 4 detects impurities on the surface of the flexible screen, the electromagnetic push cylinder 5 controls the position of the limit push rod 6, so that the slider insertion port 402 and the push rod top block 601 are interleaved, and the product... Folding compresses the particle infrared detector 4. Due to the contact between the push rod top block 601 and the detector slider 401, the particle infrared detector 4 cannot retract, preventing the product from folding. This avoids impurities compressing the screen and causing damage, cracking, or even leakage to the flexible screen. If the particle infrared detector 4 detects no impurities on the surface of the flexible screen, the electromagnetic push cylinder 5 controls the position of the limit push rod 6, aligning the slider insertion port 402 with the push rod top block 601. As the product folds, the particle infrared detector 4 is compressed, allowing it to retract into the protective frame 1, enabling the product to fold without obstruction.
