Description

Technical Field

[0001] This utility model relates to the field of LED displays, and in particular to an impact-resistant protective structure for LED displays. Background Technology

[0002] LED displays are a type of display that controls semiconductor light-emitting diodes (LEDs), consisting of tens of thousands to hundreds of thousands of LED pixels arranged uniformly. LED displays utilize the electroluminescence principle of semiconductor PN junctions. When current passes through the PN junction, electrons and holes recombine, releasing photons. The band gap of the semiconductor material determines the wavelength (color), thus emitting different colors of light. By mixing different brightness levels of red, green, and blue primary color LEDs, various colors can be generated, thereby forming color images.

[0003] In the actual transportation and use of LED displays, packaging materials such as foam, bubble wrap, or cardboard are generally used for impact protection during transport. These materials effectively absorb and disperse the impact forces that may be generated during transportation, thereby reducing the risk of damage to the display. However, although these packaging materials provide protection to a certain extent, they still cannot completely guarantee the integrity of the display. During transportation, if the display is subjected to severe vibration or falls from a height, the packaging materials may break, leading to damage to the display. Therefore, in addition to using appropriate packaging materials, it is also necessary to handle the display with care during transportation to ensure its safety.

[0004] During use, LED displays are difficult to protect with packaging materials such as foam. Firstly, LED displays are typically installed in fixed locations, such as walls, brackets, or stages, making it impossible for foam or similar packaging materials to provide continuous protection. Secondly, LED displays are exposed to various environmental conditions and physical stresses during use, such as temperature changes, humidity, dust, and vibration, all of which can affect the display's performance and lifespan. Furthermore, LED chips are prone to detachment or failure, a problem that is difficult to prevent using foam or similar packaging materials. Utility Model Content

[0005] The main objective of this invention is to provide an impact-resistant protective structure for LED displays, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An impact-resistant protective structure for an LED display screen includes a display screen, an outer frame, a back cover, and buttons. The rear end of the back cover is connected to the outer frame, the display screen is installed in the outer frame and the back cover, and the buttons are installed on the outer frame. The back cover has a back protective cover at the center of the back, and the corners of the back protective cover have protrusions. The end face of the protrusions has a waist hole. A buffer connector is inserted into the waist hole and a movable connecting strip is connected to it. When the movable connecting strip moves, it drives the buffer connector to move in the waist hole. The outer frame is provided with an L-shaped protective corner shield at the corner, and the side wall of the L-shaped protective corner shield is provided with a through groove. Multiple buffer strips are installed in the through groove of the L-shaped protective corner shield. The L-shaped protective corner shield is connected to the movable connecting strip through a fastener.

[0007] In a preferred embodiment of this application, the two ends of the L-shaped protective corner shield are semi-circular, and a ring adapted to the fixing component is provided at the corner of the L-shaped protective corner shield. The ring, the buffer strip and the L-shaped protective corner shield are designed as a whole and are all made of buffer plastic material. In a preferred embodiment of this application, the inner wall edge of the L-shaped protective corner shield is provided with a baffle strip, which is adapted to the outer frame and the back shell. The L-shaped protective corner shield is bonded to the outer frame. Multiple buffer strips are obliquely arranged in the through groove and are equidistantly distributed. In a preferred embodiment of this application, the back protective cover and the protrusion are designed as an integral part, the outer end of the protrusion is arc-shaped, and the connection between the protrusion and the back protective cover is arc-shaped. The cross-section of the waist hole is "T"-shaped. The buffer connector is composed of a bolt, a nut, and a buffer sleeve. The bolt is inserted into the round hole on the waist hole and the movable connecting strip and the nut is fitted on it. The buffer sleeve is fitted on the bolt, and the nut restricts the bolt and the buffer sleeve from falling off. In a preferred embodiment of this application, the movable connecting strip is designed in an elliptical shape, and the fixing component consists of a fixing screw and a fixing nut. The fixing screw passes through the round hole on the end face of the movable connecting strip and the round hole on the end face of the L-shaped protective corner cover, and the fixing nut is fitted on it to realize the connection between the movable connecting strip and the L-shaped protective corner cover. In a preferred embodiment of this application, a buffer rubber block is provided between the back protective cover and the back shell to achieve buffer protection between the two. The back protective cover has multiple through holes on its end face, and the multiple through holes are evenly distributed.

[0008] Compared with the prior art, the present invention has the following beneficial effects: The design of the back cover and its integrated structure with the protrusion, along with the cooperation of the movable connecting strip and the buffer connector, enable the device to effectively absorb and disperse the impact force when subjected to external impact, reducing the impact on core components such as the display screen.

[0009] The movable connecting strip and the buffer connector are connected to the rear shell through waist holes. This design not only allows the connector to move under impact but also ensures the reliability of the connection, preventing loosening or damage caused by impact. Meanwhile, the L-shaped protective corner guards are connected to the movable connecting strip via fasteners, forming a robust protective structure that further enhances the overall stability of the equipment.

[0010] The multiple through holes on the end face of the back protective cover are evenly distributed, which not only ensures ventilation and heat dissipation of the structure, but also does not affect the overall protective performance. This ensures that the equipment will not be affected by overheating during operation, and can also be used as the installation position for adjusting the angle of the equipment.

[0011] The movable connecting strip is elliptical in shape to accommodate impacts from different directions; the L-shaped protective corner guards have semi-circular ends to accommodate impacts from different angles. These designs enhance the equipment's adaptability and durability in complex environments. Attached Figure Description
