Description

Technical Field

[0001] This utility model belongs to the field of display screen installation technology, and more specifically, it relates to a carbon fiber box structure for installing acoustically transparent cinema screens. Background Technology

[0002] An acoustically transparent cinema screen mounting enclosure structure refers to a rigid support frame unit specifically designed to support and secure an acoustically transparent cinema screen. Its core function is to provide a stable mounting base for the screen. Currently, the mainstream manufacturing material for this type of enclosure structure is die-cast aluminum alloy, to meet the basic requirements of the cinema environment for structural strength, durability, and acoustic penetration.

[0003] However, traditional die-cast aluminum alloy enclosures present significant problems in practical applications. Firstly, their excessive weight significantly increases transportation and on-site installation costs, placing undue demands on the load-bearing structure of the cinema building itself. This also makes hoisting operations during routine maintenance or adjustments inconvenient and poses safety hazards. Secondly, these metal enclosures are prone to structural resonance at certain sound wave frequencies, generating unpleasant additional noise and interfering with the normal directivity of the speaker waves. This leads to increased sound attenuation and severe distortion as sound penetrates the screen, ultimately degrading the overall acoustic performance of the cinema and the audience's viewing experience. Therefore, this study aims to improve upon existing structures and address their shortcomings by providing a carbon fiber enclosure structure for acoustically transparent cinema screen installation, with the goal of achieving greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a carbon fiber enclosure structure for mounting an acoustically transparent cinema screen, which is achieved by the following specific technical means:

[0005] A carbon fiber enclosure structure for mounting an acoustically transparent cinema screen includes a carbon fiber enclosure frame. The front of the carbon fiber enclosure frame has a module mounting surface for fixing LED modules. The carbon fiber enclosure frame includes a rectangular outer frame, and a cross is provided inside the rectangular outer frame. The interior of the carbon fiber enclosure frame has a cavity filled with PU foam material to form an embedded PU foam layer. The vertical beam of the cross is provided with a power supply compartment. A front aluminum plate and a rear heat dissipation aluminum plate are respectively installed on the front and rear sides of the power supply compartment by magnetic attraction. The front side of the front aluminum plate is flush with the module mounting surface.

[0006] Furthermore, the cross-shaped structure has multiple sets of mounting slots corresponding to the front aluminum plate and the rear heat dissipation aluminum plate, and iron sheets are fixedly embedded inside the mounting slots. Magnets are fixedly embedded in the iron sheets corresponding to the front aluminum plate and the rear heat dissipation aluminum plate.

[0007] Furthermore, the surface of the rear heat dissipation aluminum plate is provided with multiple sets of heat dissipation fins.

[0008] Furthermore, one end of the rear heat dissipation aluminum plate is provided with mounting holes for mounting a cooling fan.

[0009] Furthermore, the sides of the carbon fiber housing frame are equipped with cable routing holes.

[0010] Furthermore, positioning holes are provided at both the top and bottom ends of the carbon fiber box frame for installing positioning posts.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model uses carbon fiber composite material as the main body of the enclosure frame. Compared with traditional die-cast aluminum alloy enclosures, it achieves extreme lightweighting, significantly reducing the overall cost of raw materials, transportation, and on-site hoisting. It also greatly reduces the load-bearing requirements of the cinema building structure, making handling operations during daily maintenance and adjustments safer and more convenient, effectively avoiding the safety hazards of traditional solutions. Simultaneously, addressing the heat dissipation bottleneck, the magnetically installed high-efficiency heat dissipation aluminum plate significantly improves power supply stability and service life, perfectly solving the problem of insufficient thermal conductivity of carbon fiber. Furthermore, the magnetically attached front and rear heat dissipation aluminum plate design enables quick, manual disassembly of the power supply compartment, effectively improving maintenance efficiency and greatly saving maintenance time and labor costs.

[0013] 2. This utility model fills the cavity of the carbon fiber frame with PU foam material to form an embedded high-damping layer, giving the enclosure excellent vibration attenuation characteristics. This transforms it from a "resonance amplifier" of the traditional die-cast aluminum enclosure into a highly efficient "vibration eliminator," suppressing harmful structural resonance at its source, completely eliminating additional noise and sound directionality interference caused by resonance, and significantly reducing the attenuation and distortion of sound when it penetrates the screen. This achieves a high-fidelity sound transmission effect and greatly improves the overall acoustic performance of the cinema and the audience experience. Attached Figure Description

[0028] Example:

[0029] As attached Figure 1 To be continued Figure 5 As shown:

[0030] This utility model provides a carbon fiber enclosure structure for mounting a sound-transparent cinema screen, including a carbon fiber enclosure frame 1. The front of the carbon fiber enclosure frame 1 is provided with a module mounting surface for fixing LED modules. The carbon fiber enclosure frame 1 includes a rectangular outer frame, and a cross 101 is provided inside the rectangular outer frame. The carbon fiber enclosure frame 1 is formed by hot-pressing and curing multiple layers of carbon fiber to constitute the main load-bearing structure of the enclosure. At the same time, the carbon fiber material, with its extremely high specific strength and specific modulus, achieves a significant reduction in weight (more than 40%) while ensuring the same or even higher structural stiffness as aluminum alloy enclosures. The interior of the carbon fiber enclosure frame 1 is provided with a cavity, and the cavity is filled with PU foam material to form an embedded PU foam layer. This foam layer and the carbon fiber enclosure frame 1 form a "constraint layer damping" structure. When sound waves impact the enclosure and attempt to induce vibration, the PU foam material, as a viscoelastic material with high damping characteristics, can effectively retain the carbon fiber. The mechanical energy of vibration transmitted from the fiber plate is converted into heat energy and dissipated, which greatly suppresses the overall resonance amplitude of the enclosure and cuts off the "vibration-resonance-noise" chain in the propagation path, thereby eliminating sound coloration and ensuring high-fidelity sound wave penetration. The vertical beam of the cross 101 is equipped with a power supply compartment 102. The front aluminum plate 2 and the rear heat dissipation aluminum plate 3 are respectively installed on the front and rear sides of the power supply compartment 102 by magnetic attraction. Thermal grease pads are pasted on the inner side of both the front aluminum plate 2 and the rear heat dissipation aluminum plate 3. After installation, the thermal grease pads are tightly attached to the metal shell of the power supply inside the power supply compartment 102. The front side of the front aluminum plate 2 is flush with the module mounting surface. In addition, the magnetic installation provides a structural basis for quick disassembly and maintenance of the power supply compartment. The thermal grease pads pasted on the inner side of the front and rear aluminum plates are tightly attached to the metal shell of the power supply after installation, effectively filling the micro gaps and creating an efficient and continuous heat conduction path for the heat generated by the power supply to be transferred to the heat dissipation medium (aluminum plate).

[0031] Among them, the cross 101 is provided with multiple sets of mounting slots corresponding to the front aluminum plate 2 and the rear heat dissipation aluminum plate 3, and iron plates 4 are fixedly embedded inside the mounting slots. Magnets 5 are fixedly embedded in the iron plates 4 corresponding to the front aluminum plate 2 and the rear heat dissipation aluminum plate 3. The cooperation design of the iron plates 4 and the magnets 5 ensures the stability of the aluminum plate installation, and allows the aluminum plate to be disassembled or installed in a few seconds without any tools, which greatly simplifies the inspection and maintenance process of the power supply compartment and significantly reduces maintenance time and labor costs.

[0032] The rear heat dissipation aluminum plate 3 has multiple sets of heat dissipation fins on its surface. The heat dissipation fins significantly increase the heat dissipation surface area of ​​the rear heat dissipation aluminum plate 3, enhance its ability to quickly dissipate the heat of the power supply through air convection, effectively reduce the operating temperature of the power supply, and extend the life of the power supply.

[0033] The rear heat dissipation aluminum plate 3 has a mounting hole 301 at one end for mounting a cooling fan. The mounting hole allows for the addition of a cooling fan to further enhance heat dissipation performance. By using forced convection to quickly remove heat, the power supply can operate stably under high load or high temperature conditions, thus improving system reliability.

[0034] The carbon fiber enclosure frame 1 has cable guide holes 103 on each side. These holes provide a pre-set, convenient cable routing channel for connecting LED modules and power supplies, simplifying the internal wiring of the enclosure, making installation neater and faster, and reducing the risk of cable damage.

[0035] The carbon fiber box frame 1 has positioning holes 104 at both the top and bottom for installing positioning posts. By cooperating with the positioning holes and positioning posts, quick and accurate alignment can be achieved when multiple box units are spliced ​​and installed, laying the foundation for subsequent quick locking.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
