Description

Technical Field

[0001] This utility model relates to the field of display equipment technology, and in particular to a cabinet structure for constituting an LED display screen, specifically an LED display cabinet structure that requires no welding, uses mechanical connections and precise positioning. Background Technology

[0002] As a mainstream large-size display solution, LED displays are widely used in outdoor advertising, stage backdrops, command centers, and other applications. LED displays are typically composed of several independent LED display cabinets; therefore, the manufacturing process, structural stability, and installation precision of the cabinets directly determine the final quality of the entire display.

[0003] In existing technologies, LED display cabinets are generally manufactured using a metal sheet welding process. This process has significant drawbacks: First, the welding process requires specialized equipment and skilled workers, is complex, and has a long production cycle, resulting in high manufacturing costs; second, the high temperatures generated during welding cause changes in the internal stress and physical deformation of the metal material, often leading to a decrease in the flatness of the cabinet, requiring subsequent grinding and correction processes, which further increases costs and labor time.

[0004] Furthermore, when installing LED modules on the cabinet, screw fixing or simple planar magnetic attraction is often used. While screw fixing is secure, it is cumbersome and inefficient; while simple planar magnetic attraction, due to magnetic force, can easily cause modules to be attracted and lifted or shift in position, resulting in uneven gaps or height differences between modules, which seriously affects the flatness of the display screen and the viewing effect. Installers need to make repeated adjustments to achieve a usable standard, making it difficult to guarantee installation accuracy and efficiency.

[0005] Therefore, how to provide a housing structure that requires no welding, is low in cost, has a stable structure, and enables rapid and precise installation of LED modules is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] (I) The technical problem to be solved by the utility model

[0007] The main purpose of this utility model is to overcome the shortcomings of the prior art and provide a solderless LED display cabinet structure, which aims to solve the problems of high cost and easy deformation caused by the reliance on welding in the existing cabinet structure, as well as the problems of low efficiency and poor precision in the installation method of LED modules.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A solderless LED display cabinet structure includes: a profile frame; a front panel mounted on the profile frame; and at least one LED module mounted on the front panel.

[0011] Its key innovation lies in the fact that the front panel is provided with an integrated bending part and a reinforcing plate fixed to the bending part. A portion of the edge of the reinforcing plate is constructed as a mechanical positioning baffle, which is used to abut against a portion of the LED module, thereby achieving precise positioning of the LED module.

[0012] In a preferred embodiment, the profile frame is constructed by connecting multiple frame profiles (e.g., left and right frame profiles and top and bottom frame profiles) in a non-welding manner using corner brackets.

[0013] In another preferred embodiment, the inner wall of the profile frame is provided with a first groove, and the edge of the front panel is detachably embedded in the first groove. This inlay-type connection structure uses the rigidity of the profile frame to constrain the edge of the front panel, which can effectively suppress the bending deformation of the front panel caused by its own stress or external force.

[0014] As a further optimization, this utility model also includes a back cover. The inner wall of the profile frame is also provided with a second groove, and the edge of the back cover is also detachably embedded in the second groove, thereby playing a similar role in resisting deformation and facilitating maintenance of the interior of the box.

[0015] To further ensure the flatness of the enclosure, at least one panel strip can be provided between the front panel and the profile frame to finely adjust the surfaces of the front panel and the profile frame so that they are flush.

[0016] In terms of specific connection methods, the reinforcing plate can be fixed to the bent portion of the front panel by riveting, screwing, or bonding. Among these, riveting is a preferred method due to its low cost and reliable connection.

[0017] To facilitate positioning, the LED module is equipped with a magnetic component. Under the action of magnetic force, the module is attracted to the front panel. At the same time, the magnetic component abuts against the mechanical positioning baffle, thereby achieving more precise positioning through mechanical limiting on the basis of magnetic attraction.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention has one or more of the following beneficial effects:

[0020] Completely weld-free, low cost and high efficiency: This utility model uses standard parts such as profiles, corner brackets and rivets for fully mechanical connection, completely eliminating the traditional welding process. No professional welding equipment and personnel are required, the production process is greatly simplified, the manufacturing cost is significantly reduced and the production efficiency is greatly improved.

[0021] Stable structure and strong resistance to deformation: The innovative design of embedding the edges of the front panel and the rear cover into the profile frame groove forms a mutually constrained inlay locking structure, which effectively suppresses the bending deformation of the plate and ensures the high flatness and structural stability of the box under long-term use.

[0022] Precise positioning and quick installation: The unique integrated design of "reinforcing plate + mechanical positioning baffle" provides a simple and reliable physical positioning benchmark for LED module installation. During installation, the module is precisely positioned by the baffle while being magnetically attracted, eliminating positional deviation and height differences, achieving an "instant accuracy" installation effect, and greatly improving on-site construction efficiency and screen splicing quality.

[0023] Easy maintenance and high flexibility: The embedded back cover design makes it extremely easy to disassemble and assemble, facilitating quick inspection or replacement of internal components such as power supply and control cards, reducing the difficulty and cost of later maintenance.

[0035] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0036] Please see Figures 1 to 7 This utility model provides a solderless LED display cabinet structure.

[0037] The enclosure mainly consists of a rectangular frame made up of left and right side frame profiles (5), top and bottom frame profiles (6), and corner brackets (1). In the assembly process, firstly, two left and right side frame profiles (5) and two top and bottom frame profiles (6) are taken and fastened at their four corners using corner brackets (1) and screws (not shown in the figure) to form a high-strength frame. This process is a purely mechanical connection without welding, thus avoiding thermal deformation. The inner walls of the frame, facing the front and rear of the enclosure, have slots for mounting panels.

[0038] Please refer to this carefully. Figure 1 and Figure 7 The four edges of the front panel (2) are precisely embedded into the first groove facing forward on the inner wall of the profile frame. This inlay structure ensures that the edges of the front panel (2) are firmly constrained by the profile frame (5), effectively resisting bending deformation even if the panel itself has certain internal stress or is subjected to external force. In order to make the surface of the front panel (2) precisely flush with the surface of the profile frame (5, 6), a panel strip (4) is also installed between the two for adjustment.

[0039] One of the core innovations of this embodiment lies in the internal structure of the front panel (2). Please refer to... Figure 5 The enlarged view shows that the front panel (2) is formed into an integrated bent section through stamping or bending processes. Then, a panel reinforcement plate (3) of a specific shape is firmly fixed to the bent section by a riveting piece (13). The panel reinforcement plate (3) achieves a dual function: firstly, it acts as a reinforcing rib, significantly improving the overall mechanical strength and rigidity of the front panel (2); secondly, its lower or upper edge forms a precise mechanical positioning baffle with a defined height.

[0040] When installing the LED module (11), the worker only needs to roughly align the module (11) with the installation position on the front panel (2). The magnetic component (12) on the back of the module (11) will magnetically attract the module to the front panel (2). During this process, the magnetic component (12) will naturally fall or move up until its edge abuts against the mechanical positioning baffle formed by the panel reinforcement plate (3). At this time, the position of the module (11) in the vertical direction is precisely defined, thereby ensuring that all installed modules are on the same horizontal line, achieving fast and highly accurate installation.

[0041] Please see Figure 2 and Figure 7 The rear cover (10) of the enclosure also adopts a similar installation method as the front panel (2). Its edge is also embedded into the second groove facing the rear of the inner wall of the profile frame (5) and locked with screws (not shown in the figure). This design also serves to prevent the rear cover (10) from deforming and allows it to be easily disassembled for inspection and maintenance of electronic components such as the power supply (8) and control card (9) installed on its inner wall.

[0042] In addition, a cabinet connecting lock (7) is installed on the side of the profile frame, which is used to tighten and align multiple independent cabinets when splicing them into a large display screen.

[0043] 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 scope of the claims.
