Description

Technical Field

[0001] This invention relates to the field of flexible LED screen technology, specifically to a modular flexible LED screen with customizable shape and resolution. Background Technology

[0002] In the existing technology, flexible LED screen is a high-resolution display screen that is spliced ​​together from multiple small modules, each of which can be freely bent, twisted and stretched. It can be customized in shape and resolution according to specific needs. This modular flexible LED screen can be flexibly applied in different scenarios, such as indoor and outdoor billboards, stage backgrounds, exhibitions and displays.

[0003] In the splicing and installation process of existing flexible LED screen modules, magnets are usually used to attach the modules. However, since there is no auxiliary alignment structure between the magnets, workers often need to carefully observe the corresponding positions of the magnets. If the operation is not careful enough, the magnets may become misaligned, resulting in inaccurate magnet connection. Misaligned magnets will cause the stability of the flexible LED screen to decrease after installation. Under the action of vibration or other external forces, it may shift, or even loosen or fall off, posing safety hazards to viewers and users, affecting the performance and lifespan. At the same time, misaligned connections will also seriously affect the display effect of the flexible LED screen, causing problems such as image distortion and uneven brightness, thereby reducing the viewing experience for viewers.

[0004] Furthermore, if the pre-installed magnet is in an open or semi-open environment, it will be affected by airflow, causing dust and airborne particles to adhere to its surface. During the subsequent installation of the flexible LED screen module, this will form an obstacle, reducing the smoothness of the pre-installed magnet surface and increasing the gap between the pre-installed magnet and the flexible LED screen module. This will reduce the contact area, and since the magnetic force of a magnet is usually transmitted through a tight connection, the transmission of magnetic force will be blocked if there is a gap, thereby weakening the adsorption effect and preventing the flexible LED screen module from being firmly adsorbed and installed, affecting subsequent use.

[0005] Therefore, in view of this, the present invention proposes a modular flexible LED screen with customizable shape and resolution to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a modular flexible LED screen with customizable shape and resolution that can assist in aligning and connecting the second magnet and the positioning magnet; can clean dust from the surface of the positioning magnet; and can cover and shield the positioning magnet when not in use, thereby solving the corresponding technical problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a modular flexible LED screen with customizable shape and resolution, comprising a flexible LED screen body, a connecting frame, and a pre-installation plate, wherein the connecting frame is fixedly connected to the side of the flexible LED screen body facing the pre-installation plate, and positioning magnets are symmetrically fixedly connected to the pre-installation plate; the modular flexible LED screen with customizable shape and resolution includes a connecting mechanism and an auxiliary positioning mechanism, wherein the connecting mechanism is disposed on the connecting frame, and the auxiliary positioning mechanism is disposed on the pre-installation plate;

[0008] The connecting mechanism is used to connect the flexible LED screen body to the pre-installation plate;

[0009] The auxiliary positioning mechanism is used to align and mount the flexible LED screen body onto the pre-mounting plate.

[0010] Preferably, the connecting mechanism includes an extension column symmetrically fixedly connected to the connecting frame on the side facing the pre-installation plate, and an L-shaped locking block symmetrically fixedly connected to the outer ring surface of the extension column.

[0011] Preferably, a second magnet is fixedly connected to the end face of the extension column away from the connecting frame, and the second magnet is adapted to the positioning magnet.

[0012] Preferably, the auxiliary positioning mechanism includes a fixing ring symmetrically arranged on the pre-installation plate facing the connecting frame, and a fixing plate is symmetrically fixedly connected to the fixing ring. The fixing plate has a slot on the side facing the connecting frame, and the slot is adapted to the L-shaped block.

[0013] Preferably, torsion spring shafts are symmetrically fixedly connected between the fixed plates, and a linkage plate is rotatably connected to the outer surface of the torsion spring shafts.

[0014] Preferably, the end of the linkage plate away from the torsion spring shaft is rotatably connected to a fixed shaft, and a fixed frame is fixedly connected between the two ends of the fixed shaft.

[0015] Preferably, each of the fixing frames is fixedly connected to a protective cover plate on an opposite side, and a fixing block is symmetrically fixedly connected to the protective cover plate. A slider is fixedly connected to the side of the fixing block facing the pre-installation plate.

[0016] Preferably, the pre-installation plate has symmetrical grooves on one side facing the connecting frame, and the slider is slidably connected in the groove. The protective cover is slidably connected to the pre-installation plate through the slider and the groove.

[0017] Preferably, a cleaning cotton is provided on the side of the protective cover away from the connecting frame, and the cleaning cotton is in contact with the surface of the positioning magnet. The cleaning cotton is used to clean the dust and impurities attached to the surface of the positioning magnet.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) By using the connection mechanism and the auxiliary positioning mechanism together, the second magnet and the positioning magnet can be made to form a corresponding state, so that the second magnet is aligned and connected to one side of the positioning magnet, thereby ensuring the installation accuracy of the flexible LED screen body, improving the stability of the flexible LED screen body during use, and preventing the flexible LED screen body from shifting, loosening or even falling under the action of external force, thus ensuring the safety of the audience and users. At the same time, by setting the auxiliary alignment, the probability of display effect problems of the flexible LED screen body can also be reduced, avoiding the problems of screen distortion and uneven brightness, thereby improving the viewing experience of the audience.

[0020] (2) By setting cleaning cotton that fits the surface of the positioning magnet on the protective cover, when the second magnet approaches the positioning magnet and aligns with it, the cleaning cotton can be driven to slide across the surface of the positioning magnet to clean the dust and impurities attached to the surface of the positioning magnet, thereby ensuring the smoothness of the surface of the positioning magnet. This reduces the gap between the positioning magnet and the second magnet when they are connected, increases the contact area between them, and allows them to fit together more tightly, ensuring the magnetic attraction between the positioning magnet and the second magnet, thus facilitating subsequent use.

[0021] (3) By setting a protective cover plate, when the positioning magnet is not connected to the flexible LED screen body, the reset movement of the torsion spring shaft can drive the protective cover plate to completely cover the surface of the positioning magnet, blocking the contact between the positioning magnet and the outside air, thereby avoiding the occurrence of dust and impurities adhering to the surface of the positioning magnet, so as to facilitate the subsequent installation of the flexible LED screen body.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Embodiments of the present invention

[0035] Please refer to Figures 1 to 4 As shown, a modular flexible LED screen with customizable shape and resolution includes a flexible LED screen body 1, a connecting frame 2, and a pre-installation plate 3. The connecting frame 2 is fixedly connected to the side of the flexible LED screen body 1 facing the pre-installation plate 3. Positioning magnets 4 are symmetrically fixedly connected to the pre-installation plate 3. The modular flexible LED screen with customizable shape and resolution includes a connecting mechanism 5 and an auxiliary positioning mechanism 6. The connecting mechanism 5 is disposed on the connecting frame 2, and the auxiliary positioning mechanism 6 is disposed on the pre-installation plate 3.

[0036] The connecting mechanism 5 is used to connect the flexible LED screen body 1 to the pre-installation plate 3;

[0037] The auxiliary positioning mechanism 6 is used to align and install the flexible LED screen body 1 onto the pre-installation plate 3;

[0038] The connecting mechanism 5 includes an extension column 501 symmetrically fixedly connected to the connecting frame 2 on the side facing the pre-installation plate 3. An L-shaped locking block 503 is symmetrically fixedly connected to the outer ring surface of the extension column 501. A second magnet 502 is fixedly connected to the end face of the extension column 501 away from the connecting frame 2, and the second magnet 502 is adapted to the positioning magnet 4.

[0039] Please refer to Figures 1 to 4 Even better: the number and position of the connecting mechanism 5 and the auxiliary positioning mechanism 6 are corresponding. The connecting frame 2 is installed on the front side of the pre-installation plate 3 through the connection of the connecting mechanism 5 and the auxiliary positioning mechanism 6, so that a more solid connection is formed between the flexible LED screen body 1 and the pre-installation plate 3.

[0040] In addition, please refer to Figures 3 to 4 The number and position of the positioning magnet 4 and the second magnet 502 are corresponding, and the positioning magnet 4 and the second magnet 502 are magnetically attracted to each other.

[0041] Further examples:

[0042] Please refer to Figures 1 to 7 As shown, the auxiliary positioning mechanism 6 includes a fixing ring 611 symmetrically arranged on the pre-installation plate 3 facing the side of the connecting frame 2, and a fixing plate 610 is symmetrically fixedly connected to the fixing ring 611. The fixing plate 610 has a slot 612 on the side facing the connecting frame 2, and the slot 612 is adapted to the L-shaped block 503.

[0043] A torsion spring shaft 609 is symmetrically fixedly connected between the fixed plates 610. A linkage plate 608 is rotatably connected to the outer surface of the torsion spring shaft 609. A fixed shaft 607 is rotatably connected to the end of the linkage plate 608 away from the torsion spring shaft 609. A fixed frame 606 is fixedly connected between the two ends of the fixed shaft 607. A protective cover plate 602 is fixedly connected to each of the fixed frames 606 on opposite sides. A fixed block 604 is symmetrically fixedly connected to the protective cover plate 602. A slider 605 is fixedly connected to the side of the fixed block 604 facing the pre-installation plate 3.

[0044] The pre-installation plate 3 has symmetrical grooves 601 on one side facing the connecting frame 2, and the slider 605 is slidably connected in the groove 601. The protective cover plate 602 is slidably connected to the pre-installation plate 3 through the slider 605 and the groove 601.

[0045] A cleaning cotton 603 is provided on the side of the protective cover plate 602 away from the connecting frame 2, and the cleaning cotton 603 is attached to the surface of the positioning magnet 4. The cleaning cotton 603 is used to clean the dust and impurities attached to the surface of the positioning magnet 4.

[0046] Please refer to Figure 6 Even better: the L-shaped block 503 and the slot 612 are in the same position. During the magnetic attraction between the second magnet 502 and the positioning magnet 4, the end of the L-shaped block 503 away from the connecting frame 2 is inserted into the slot 612. And by means of snapping, as the connecting frame 2 moves as a whole, the fixing ring 611 is pushed toward the pre-installation plate 3.

[0047] In addition, the torsion spring shaft 609 is composed of a torsion spring and a rotating shaft structure. When the fixed ring 611 moves towards the pre-installation plate 3, it is affected by external force, and the linkage plate 608 between the torsion spring shaft 609 and the fixed shaft 607 rotates synchronously to cooperate with the movement of the fixed ring 611. When the flexible LED screen body 1 is not installed, the L-shaped card block 503 and the card slot 612 are not in contact. Affected by the torsion spring shaft 609, the fixed ring 611 will be reset.

[0048] The effects achieved by this embodiment are as follows: During the splicing and installation of existing flexible LED screen modules, if the operators are not careful enough, misalignment can occur between the magnets, leading to inaccurate magnet connection. This results in decreased stability of the flexible LED screen after installation, causing displacement under vibration or other external forces, and even loosening or falling off, posing safety hazards to viewers and users, affecting the performance and lifespan. Furthermore, misaligned connections severely impact the display effect of the flexible LED screen, causing image distortion and uneven brightness, thus reducing the viewing experience. Compared to existing technologies, the connecting mechanism 5 and auxiliary fixing... The use of the positioning mechanism 6 helps the second magnet 502 and the positioning magnet 4 to form a corresponding state, so that the second magnet 502 is aligned and connected to one side of the positioning magnet 4, thereby ensuring the installation accuracy of the flexible LED screen body 1, improving the stability of the flexible LED screen body 1 during use, and preventing the flexible LED screen body 1 from shifting, loosening, or even falling under the action of external force, thus ensuring the safety of viewers and users. At the same time, through the auxiliary alignment setting, the probability of display effect problems of the flexible LED screen body 1 can also be reduced, avoiding problems such as screen distortion and uneven brightness, thereby improving the viewing experience of viewers.

[0049] Secondly, the cleaning cotton 603 can simultaneously clean the surface of the positioning magnet 4 during the alignment and connection of the second magnet 502 and the positioning magnet 4, thereby ensuring the smoothness of the surface of the positioning magnet 4. This reduces the gap between the positioning magnet 4 and the second magnet 502 when they are connected, increases the contact area between them, and allows them to fit together more tightly, ensuring the magnetic attraction between the positioning magnet 4 and the second magnet 502, thus facilitating subsequent use.

[0050] Furthermore, by using the protective cover 602, when the positioning magnet 4 is not connected to the flexible LED screen body 1, the torsion spring shaft 609 can drive the protective cover 602 to completely cover the surface of the positioning magnet 4, blocking the contact between the positioning magnet 4 and the outside air, thereby avoiding the occurrence of dust and impurities adhering to the surface of the positioning magnet 4, so as to facilitate the subsequent installation of the flexible LED screen body 1.

[0051] The complete usage steps and working principle of the above embodiments are as follows:

[0052] It should be noted that the pre-installation plate 3 can be pre-installed on the flexible LED screen body 1 at the required installation position using bolts or other fixing structures. The flexible LED screen body 1 can be customized into a module with a specific shape and resolution according to user needs. The pre-installation plate 3 is made into a modular structure of the same size as the flexible LED screen body 1 to facilitate the installation of the flexible LED screen body 1. By splicing multiple flexible LED screen bodies 1 and pre-installation plates 3 together and connecting the circuit, the function of viewing the screen can be provided to the user.

[0053] In the initial state: when the flexible LED screen body 1 is not connected to the pre-installation plate 3, the second magnet 502 is not magnetically attracted to the positioning magnet 4, and the end of the L-shaped block 503 is not locked in the slot 612, so that the fixing ring 611 is in a state away from the pre-installation plate 3 under the action of the torsion spring shaft 609, and the protective cover 602 covers the surface of the positioning magnet 4, so that the positioning magnet 4 is isolated from the external environment;

[0054] The following describes the working process of the auxiliary positioning mechanism 6 aligning and installing the flexible LED screen body 1 onto the pre-installation plate 3:

[0055] During the process of installing the flexible LED screen body 1 onto the front side of the pre-installation plate 3, as the flexible LED screen body 1 approaches the pre-installation plate 3, the extension column 501 moves synchronously towards the pre-installation plate 3, engaging the end of the L-shaped locking block 503 away from the connecting frame 2 into the locking groove 612, thus forming a tighter connection between the extension column 501 and the fixing ring 611. Simultaneously, the flexible LED screen body 1 continues to move towards the pre-installation plate 3, and under the pushing force of the extension column 501, it drives the fixing ring 611 to move synchronously towards the pre-installation plate 3. At this time, the linkage plate 608 rotates between the torsion spring shaft 609 and the fixing shaft 607 to cooperate with the approach of the fixing ring 611. Since the end of the linkage plate 608 near the pre-installation plate 3 is provided with a protective cover plate 602, and the protective cover plate 602 slides over the front side of the positioning magnet 4, such as... Figures 4 to 6 As shown, while the linkage plate 608 rotates, the end of the linkage plate 608 facing the pre-installation plate 3 moves away from each other, driving the two protective covers 602 to move back to back on the pre-installation plate 3, exposing the covered positioning magnet 4. When the protective cover 602 is opened to its maximum extent, the second magnet 502 will just be attached to the surface of the positioning magnet 4, and under the action of magnetic force, they will form a mutual magnetic attraction state, so that the second magnet 502 is aligned and attached to the surface of the positioning magnet 4. Through the combined use of the connecting mechanism 5 and the auxiliary positioning mechanism 6, the second magnet 502 and the positioning magnet 4 can be aligned and attached. The iron 4 forms a corresponding state, so that the second magnet 502 is aligned and connected to one side of the positioning magnet 4, thereby ensuring the installation accuracy of the flexible LED screen body 1, improving the stability of the flexible LED screen body 1 during use, and preventing the flexible LED screen body 1 from shifting, loosening, or even falling under the action of external force, thus ensuring the safety of the audience and users. At the same time, through the auxiliary alignment setting, the probability of display effect problems of the flexible LED screen body 1 can also be reduced, avoiding problems such as screen distortion and uneven brightness, thereby improving the viewing experience of the audience.

[0056] At the same time, during the process of the protective cover plates 602 separating and moving, such as Figure 7 As shown, since the protective cover plate 602 is provided with cleaning cotton 603 on the side facing the pre-installation plate 3, and the cleaning cotton 603 is attached to the surface of the positioning magnet 4, as the protective cover plate 602 moves, it can slide synchronously with the protective cover plate 602 onto the surface of the positioning magnet 4 to clean and remove the dust and impurities attached to the surface of the positioning magnet 4, ensuring the smoothness of the surface of the positioning magnet 4, reducing the gap between the positioning magnet 4 and the second magnet 502, increasing the contact area between the two, so that the two can be attached more tightly together, ensuring the magnetic attraction between the positioning magnet 4 and the second magnet 502, and thus facilitating subsequent use;

[0057] In addition, such as Figure 2 , Figure 4 as well as Figure 5 As shown, by means of the protective cover plate 602, when the positioning magnet 4 is not connected to the flexible LED screen body 1, the reset movement of the torsion spring shaft 609 can drive the protective cover plate 602 to completely cover the surface of the positioning magnet 4, blocking the contact between the positioning magnet 4 and the outside air, thereby avoiding the occurrence of dust and impurities adhering to the surface of the positioning magnet 4, so as to facilitate the subsequent installation of the flexible LED screen body 1.
