Detailed Implementation

[0027] 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 embodiments of this utility model, not all embodiments.

[0028] Referring to the accompanying drawings, this utility model provides a splicing cinema screen cabinet, the core of which lies in the combination and splicing of two different sizes of die-cast cinema screen cabinets to form large cabinets of various sizes to meet the needs of different cinema screens.

[0029] This utility model discloses a modular cinema screen enclosure 100, comprising a body 1, a plastic shell 2, and a plastic back cover 3. The body 1, serving as the basic frame of the enclosure, is made of aluminum alloy using a die-casting process, possessing high strength and flatness advantages to ensure a high degree of flatness after assembly. The plastic shell 2 covers the rear of the body 1, working together with the body to protect the internal components, while its structural design allows for quick assembly with the plastic back cover 3. A window 4 is located in the center of the plastic shell 2, extending towards the center to form a retaining edge 5, used for installation with the plastic back cover 3 and limiting the installation position of the plastic back cover. The plastic back cover 3 is installed inside the window 4, its outer edge conforming to the contour of the window 4, ensuring sealing and stability after installation. A tongue 7 is provided below the plastic back cover 3, inserting into the slot 6 at the lower part of the window 4 of the plastic shell 2, forming a staggered installation structure to further enhance the connection's firmness.

[0030] The plastic back cover 3 has a connecting piece 8 at its front end, with a buckle 9 on the connecting piece 8. The outer side of the buckle 9 has a guide slope 10, which engages with the inner side of the retaining edge 5 of the plastic housing 2. This facilitates the buckle 9's movement from the rear to the front of the retaining edge 5, ultimately allowing the rear end of the buckle 9 to abut against the front end of the retaining edge 5 for a snap-fit ​​connection. This snap-fit ​​structure can be configured on either side of the window. The connecting piece 8 is an elastic piece, and its elasticity allows the buckle 9 to automatically adjust its position and fit tightly during installation. The plastic back cover 3 also has a captive screw 11, which engages with the locking hole 13 on the plastic housing 2 to further enhance the stability of the fixation. The tongue is positioned below the front of the plastic back cover, creating a front-to-back misalignment. A notch 13 is formed in the center of the lower retaining edge, and the insertion port 6 is positioned directly below the notch.

[0031] The main body 1 and the plastic shell 2 are connected by a locking screw 14, preferably an M4 screw, to ensure the stability of the two. The plastic shell is provided with a connecting post 15, and the locking screw 14 is disposed in the connecting post 15. The main body is provided with a connecting hole 28 corresponding to the connecting post, and the locking screw can be screwed into the connecting hole.

[0032] The main body is a square component. Reinforcing members 18 are located at the rear corners of the main body 1, forming an L-shape, and include a first connecting piece 19 and a second connecting piece 20. Bolts 21 are mounted on the first connecting piece 19, and screw holes 22 are mounted on the second connecting piece 20. The connection between the two main bodies 1 is achieved through the engagement of the bolts 21 and screw holes 22. A space 23 is formed between the two reinforcing members 18 located on the same side. A matching connector 24 is mounted on the plastic housing 2, inserted into the space. The connector 24 has a first opening 25 for wire harnesses to pass through, such as power and signal cables during cinema screen installation. A second opening 26 is located in the middle of the main body 1, also for wire harnesses to pass through, such as power and signal cables from LED modules. A support platform 27 is mounted on the main body 1, located inside the reinforcing body 18. The rear end face of the support platform 27 abuts against the front end face of the plastic shell 2. The cinema screen cabinet is fixed to the mounting frame by a locking device (not shown in the figure, but can be an M8 screw). The support platform 27 is provided with a first connecting hole 16, and the plastic shell 2 is provided with a second connecting hole 17. The locking device is connected to the first connecting hole 16 and the second connecting hole 17 to fix the cabinet. The first connecting hole and the second connecting hole can be M8 threaded holes. During the installation of the entire screen, the locking device (which can be an M8 screw) is used to lock the entire cabinet onto the mounting frame (not shown in the figure, but can be a steel structure) through the two connecting holes.

[0033] This utility model's die-cast housing for cinema screens is designed in two sizes: 320mm×320mm or 320mm×480mm, with a module size of 320mm×160mm. By assembling and locking the cinema screen housings together, large housings of the following sizes can be formed: 640mm×480mm, 960mm×480mm, 960mm×960mm, 640mm×960mm, 640mm×640mm, and 960mm×640mm. For example, when a 640mm×480mm large housing needs to be assembled, two 320mm×320mm cinema screen housings can be horizontally arranged and fixed using bolts 21 and screw holes 22 on the reinforcing body 18. When a 960mm×480mm large housing needs to be assembled, three 320mm×320mm cinema screen housings can be horizontally arranged and fixed in the same way. Similarly, other sizes of large enclosures can also be achieved through different combinations of cinema screen enclosures.

[0034] After assembly, each large cabinet can house switch units, system cards, cables, and other components, ultimately forming a cinema screen that meets 2K or 4K resolution requirements. Because the cinema screen cabinets are manufactured using a die-casting process, they possess high flatness and precision, ensuring overall flatness and stability after assembly. In practical applications, depending on the specific needs of the cinema, appropriate combinations of cinema screen cabinets can be selected to flexibly create cinema screens of different sizes. For example, for a cinema screen requiring 2K resolution, an appropriate number of cabinets can be assembled to create a screen with a resolution close to 2048×1080; for a cinema screen requiring 4K resolution, a larger number of cabinets can be assembled to create a screen with a resolution close to 4096×2160.

[0035] The working principle of this invention lies in the combination of two types of cinema screen cabinets to form large cabinets of different sizes. In actual operation, the required size and quantity of large cabinets are first determined according to the resolution requirements of the target cinema screen, and then suitable cinema screen cabinets are selected for splicing. During the splicing process, bolts 21 and screw holes 22 on the reinforcing body 18 are used to connect the cabinets, ensuring that the overall structure after splicing is firm and stable. After splicing, the switch unit, system card, cables, and other materials are installed into the cabinet, and the cabinet is fixed to the mounting frame by the locking component 30. Finally, multiple large cabinets are spliced ​​together to form a complete cinema screen, ensuring that its resolution meets the 2K or 4K standard.

[0036] The technical solution of this utility model has significant advantages. First, by reducing the number of system cards and power supplies, for example, by using as many 960mm×960mm cabinets as possible, the overall cost of the cinema screen is reduced. Second, only two types of cinema screen cabinets need to be produced to meet the needs of cinema screens of different sizes, avoiding the problem of needing multiple molds for traditional fixed-size die-cast cabinets, thus greatly improving production efficiency. Third, the cinema screen cabinet adopts a die-casting process, resulting in good flatness, solving the problem of poor flatness after the installation of profile cabinets, and simplifying the manual assembly steps. Finally, this utility model is highly flexible and can be flexibly spliced ​​into cinema screens of different sizes according to the needs of different cinemas, making it highly adaptable.

[0037] In summary, this invention combines two types of cinema screen cabinets to form large cabinets of various sizes, thus meeting the needs of different cinema screens. This design not only reduces costs but also improves production efficiency and splicing accuracy, and has broad application prospects.
