Description

Technical Field

[0001] This utility model relates to the technical field of electronic device structural components, specifically an embedded layer display screen frame. Background Technology

[0002] The display frame (or mid-frame, bracket) is a key structural component in the display module. Its main function is to support and fix the display panel (such as LCD or OLED panel), backlight module, driving circuit and other internal components, and to provide structural support and a certain degree of protection for the entire display module. With the development of display technology, displays are evolving towards ultra-thin, high-brightness, high-refresh-rate and high-resolution, which also brings higher power consumption and more concentrated heat generation, and puts forward more stringent requirements for electromagnetic compatibility.

[0003] In existing technologies, traditional solutions for display screen frames are mainly divided into two categories: one is to use a pure structural frame, which can only provide mechanical support and positioning, but has insufficient heat dissipation and electromagnetic shielding performance; the other is to enhance performance by attaching or coating functional layers (such as heat dissipation layers, shielding layers or reinforcing components), but there are problems such as poor adhesion, complex processes, loose structure, difficult maintenance, and not conducive to the thinning of equipment.

[0004] Therefore, an embedded layer display screen frame is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an embedded layer display screen frame to solve the problems of existing display screen frame solutions mentioned in the background art, which either only meet mechanical support and have insufficient performance, or have external functional layers but suffer from poor adhesion and complex processes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an embedded layer display screen frame, including a main frame, wherein an embedded layer mounting groove is provided on the edge of the main frame, and a composite functional embedded layer is provided in the embedded layer mounting groove; The main frame is provided with a limiting component, and the composite function embedded layer is provided with a snap-fit ​​part that cooperates with the limiting component; The limiting component has a locked state and an unlocked state: in the locked state, the limiting component engages with the snap-fit ​​portion to fix the composite functional embedded layer in the embedded layer mounting slot; in the unlocked state, the limiting component separates from the snap-fit ​​portion to allow the composite functional embedded layer to be removed from the embedded layer mounting slot.

[0007] Preferably, the embedded layer mounting groove is located at the center of the four sides of the main frame.

[0008] Preferably, the composite functional embedded layer includes a metal reinforcing layer, a graphene heat dissipation layer, and an electromagnetic shielding layer, which are stacked sequentially.

[0009] Preferably, the limiting component includes a limiting element movably disposed on the main frame, the limiting element being movable relative to the main frame to engage with or disengage from the locking portion.

[0010] Preferably, the snap-fit ​​portion consists of two symmetrically arranged limiting disk slots on the composite functional embedded layer; the limiting element is a rotating limiting disk; the main frame is provided with a limiting component receiving groove corresponding to the position of each limiting disk slot to accommodate the rotating limiting disk; the rotating limiting disk has a snap-fit ​​portion that can be screwed into or out of the limiting disk slot.

[0011] Preferably, the rotating limiting disk is rotatably mounted in the receiving groove of the limiting component by fasteners and is capable of rotating about the axis of the fasteners.

[0012] Preferably, the fastener is a fastening bolt; the fastening bolt is fixedly connected to one side of the rotating limiting plate; the fastening bolt passes through the main frame and is threadedly connected to it.

[0013] Preferably, the rotating limiting disk has a drive groove on its end face for receiving external tools to drive its rotation.

[0014] Preferably, the drive slot is an internal hexagonal drive slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This embedded layer display screen frame integrates a composite structure with metal reinforcing ribs, graphene heat dissipation, and electromagnetic shielding functional layers embedded in the main frame. Lockable limiting components enable stable installation and convenient disassembly. This improves mechanical support, heat dissipation, and electromagnetic shielding performance while also ensuring structural stability, simplified manufacturing processes, and ease of equipment maintenance. The specific details are as follows: Firstly, this invention effectively integrates multiple functions such as mechanical support, efficient heat dissipation, and electromagnetic shielding by creating an embedded layer mounting groove in the main frame frame and setting a composite functional embedded layer within the groove, consisting of a metal reinforcing rib layer, a graphene heat dissipation layer, and an electromagnetic shielding layer stacked sequentially. Compared to the shortcomings of existing pure structural frames that only provide mechanical support and lack sufficient heat dissipation and electromagnetic shielding performance, as well as the problems of weak adhesion and complex processes associated with externally attached or coated functional layers, this solution embeds the functional layers into the main frame structure. This ensures a stable connection between each functional layer and the main frame, avoids the risk of loosening of external structures, simplifies the production process, and the embedded design eliminates the need for additional external space, improving the flexibility of the device's lightweight design.

[0016] Secondly, this invention achieves reliable fixation and convenient assembly / disassembly of the composite functional embedded layer and the main frame by setting a limiting component with locking and unlocking states. When the limiting component is in the locked state, the engaging part of the rotating limiting plate screws into the limiting plate slot of the composite functional embedded layer, ensuring the functional layer is firmly positioned in the mounting slot; when unlocking, only an external tool is needed to drive the rotating limiting plate out of the slot to remove the functional layer for maintenance or replacement. This design solves the problem of the existing externally attached functional layer requiring complete disassembly and cumbersome operation for maintenance, improving the convenience and economy of product maintenance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0020] like Figure 1-5 As shown, the present invention provides an embedded layer display screen frame, which aims to solve the problems of insufficient structural strength, poor heat dissipation performance and poor electromagnetic shielding effect that are common in existing display screen frames. At the same time, it enables convenient disassembly and maintenance of the core functional layer, thereby improving the practicality and service life of the product.

[0021] like Figure 2 As shown, the embedded display screen frame described in this embodiment mainly consists of three parts: a main frame 1, a multi-functional embedded layer 3, and a limiting component. The main frame 1 serves as the basic load-bearing structure of the frame, and its edge is provided with an embedded layer mounting groove 2 for installing the multi-functional embedded layer 3. The multi-functional embedded layer 3 is detachably fixed within the embedded layer mounting groove 2 by the limiting component. The limiting component switches between locked and unlocked states to fix and remove the multi-functional embedded layer 3.

[0022] The main frame 1 is integrally injection molded from high-strength engineering plastic, with ABS (acrylonitrile-butadiene-styrene copolymer) being the preferred material. This material combines good rigidity, toughness, and processing fluidity, meeting the requirements of the display screen frame for structural stability and lightweighting. To ensure that the composite functional embedded layer 3 forms a uniform integral structure with the main frame 1 after installation, the embedded layer mounting groove 2 is located at the center of the four sides of the main frame 1. The cross-section of the mounting groove is rectangular, with its length matching the length of the corresponding side frame, and its width and depth matching the thickness and width of the composite functional embedded layer 3. This ensures that the composite functional embedded layer 3 is flush with the outer surface of the main frame 1 after insertion, avoiding any protrusions or depressions that could affect the assembly of the display screen.

[0023] The composite functional embedded layer 3 is the core component for achieving multi-dimensional performance improvement of the frame. It adopts a three-layer composite structure design, consisting of a metal reinforcing rib layer 301, a graphene heat dissipation layer 302, and an electromagnetic shielding layer 303 from the inside out. The three layers are bonded and fixed in sequence with high-temperature resistant adhesive to form an integrated composite layer structure.

[0024] The metal reinforcing rib layer 301 is made of 0.8mm thick aluminum alloy sheet with anodized surface treatment. This not only significantly improves the overall structural strength and deformation resistance of the frame, preventing warping during display assembly, but also provides a stable support foundation for the subsequent heat dissipation layer and shielding layer. The graphene heat dissipation layer 302 uses graphene / silicone composite material with a thickness of 0.5mm. Utilizing the excellent thermal conductivity of graphene, it can quickly conduct the heat generated during display operation and dissipate it to the outside through the main frame 1, effectively reducing the operating temperature of the core components of the display and extending its service life. The electromagnetic shielding layer 303 uses a 0.3mm thick copper foil composite layer with an insulating protective film on its surface. This effectively shields the display from external electromagnetic interference signals and prevents electromagnetic radiation generated by the display itself from interfering with peripheral equipment, ensuring the stability of the displayed image.

[0025] To facilitate fixation with the limiting component, the two ends of the composite functional embedded layer 3 are symmetrically provided with locking parts. In this embodiment, the locking part is specifically the limiting disk slot 304. The slot is formed by stamping process, and its cross-section is fan-shaped. The depth of the slot matches the thickness of the locking part of the rotating limiting disk 5 to ensure that a stable mechanical lock can be formed after locking.

[0026] The limiting component is used to achieve a detachable connection between the composite functional embedded layer 3 and the main frame 1. It mainly includes a limiting component receiving groove 4, a rotating limiting disk 5, and a fastening bolt 502. The limiting component receiving groove 4 is opened on the main frame 1 at the position corresponding to the limiting disk slot 304. It has a stepped hole structure. The upper hole diameter is adapted to the diameter of the rotating limiting disk 5, and the lower hole diameter is matched with the thread diameter of the fastening bolt 502. This ensures that the rotating limiting disk 5 can be stably accommodated and provides an installation base for the fastening bolt 502.

[0027] The rotating limiting disc 5 has a circular structure with an integrally formed engaging part on one side. The engaging part has a fan-shaped protrusion structure, and the size of the protrusion is perfectly matched with the size of the limiting disc slot 304, ensuring that it can smoothly engage or disengage from the slot during rotation. A threaded hole is provided at the center of the rotating limiting disc 5 for installation with the fastening bolt 502. After the fastening bolt 502 passes through the threaded hole of the rotating limiting disc 5, it is threadedly connected to the main frame 1. The preload of the bolt presses the rotating limiting disc 5 into the limiting component receiving groove 4, while ensuring that the rotating limiting disc 5 can rotate flexibly around the axis of the fastening bolt 502.

[0028] To facilitate the rotation of the rotating limiting disk 5, a driving groove 501 is provided on its end face. In this embodiment, the driving groove 501 adopts an internal hexagonal drive groove structure, which has the advantages of large transmission torque and precise positioning, and can be driven to rotate by a standard internal hexagonal wrench. In other optional embodiments, the driving groove can also adopt common structures such as cross groove, slotted groove, or Torx groove, all of which can achieve the same driving effect.

[0029] Working principle: Before using this type of embedded display screen frame, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 5As shown, the metal reinforcing rib layer 301, graphene heat dissipation layer 302, and electromagnetic shielding layer 303 are first bonded together in sequence with high-temperature resistant adhesive and cured under pressure to form a composite functional embedded layer 3. Then, the composite functional embedded layer 3 is aligned with the embedded layer mounting groove 2 of the main frame 1 and pushed in along the length of the mounting groove until the two end limit plate slots 304 of the composite functional embedded layer 3 are completely aligned with the limit component receiving groove 4 on the main frame 1. Finally, an Allen wrench is inserted into the drive groove 501 of the rotating limit plate 5 and the rotating limit plate 5 is rotated clockwise until the engaging part is completely embedded in the limit plate slot 304. At this time, the limit component is in a locked state, and the composite functional embedded layer 3 is firmly fixed in the embedded layer mounting groove 2, completing the assembly.

[0030] When it is necessary to replace or maintain the composite function embedded layer 3, simply rotate the limiting plate 5 counterclockwise with an Allen wrench to completely disengage the locking part from the limiting plate slot 304. At this time, the limiting component switches to the unlocked state, and the composite function embedded layer 3 can be pulled out along the length direction of the embedded layer mounting slot 2. The operation is convenient and efficient, and there is no need to disassemble the main frame.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
