Abstract
Description
Technical Field
[0001] The present application relates to the technical field of LED display, and particularly to an LED cinema screen that prevents sound vibration. Background Art
[0002] The LED cinema screen is a major innovation in film projection technology in recent years. At present, the module installation method of the cinema screen mainly still uses the fixed connection method of positioning posts plus magnetic attraction of conventional fixed products.
[0003] The traditional fixing method has no problem in the daily application environment. However, in the cinema, in order to achieve an immersive viewing effect, the playback sound of the LED display screen is louder than usual. Under the condition of a complex vibration environment, the current LED cinema screen lacks the treatment of this special environment. Being in this environment for a long time will cause problems such as module loosening, and in severe cases, even module detachment, resulting in safety problems; module loosening will cause bright and dark lines to appear between modules, affecting the viewing experience and display effect. Utility Model Content
[0004] Based on this, in view of the problem that the LED cinema screen is prone to module loosening or even detachment due to long-term exposure to sound vibration, it is necessary to provide an LED cinema screen that prevents sound vibration.
[0005] The present utility model provides an LED cinema screen that prevents sound vibration, including an LED module and a frame. The LED module is fixedly connected to the frame. The LED module includes an LED light board and a bottom case. The bottom case includes positioning posts, and the positioning posts include a buffer structure. The buffer structure is arranged on the positioning posts and surrounds the positioning posts.
[0006] In some embodiments, the buffer structure is a silicone rubber ring.
[0007] In some embodiments, the silicone rubber ring is sleeved on the top end of the positioning post.
[0008] In some embodiments, the number of the silicone rubber rings is at least two.
[0009] In some embodiments, the positioning posts are arranged around the bottom case.
[0010] Compared with the prior art, the beneficial effect of the present utility model is that, different from the prior art, the present utility model sets positioning posts on the bottom case of the LED cinema screen, and adds silicone rubber rings on the positioning posts, so that the LED cinema screen can buffer and absorb vibration energy in the case of a large sound and complex vibration environment in the cinema, prevent the display module from falling off due to vibration or the problem of the seam becoming larger due to vibration, improve the anti-sound vibration ability of the LED cinema screen, and ensure the display effect. Description of the Drawings
[0011] One or more embodiments are exemplarily illustrated by corresponding drawings. These exemplary illustrations do not limit the embodiments. Elements with the same reference numerals in the drawings represent similar elements, unless otherwise stated. The figures in the drawings do not constitute a scale limitation.
[0012] Figure 1 This is a schematic structural diagram of the bottom shell positioning post of the LED cinema screen for preventing sound vibration in an embodiment of the present utility model. Detailed implementation manners
[0013] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
[0014] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.
[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0016] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0017] Please refer to Figure 1 , Figure 1It is a schematic structural diagram of a positioning post of the bottom case of an LED cinema screen for preventing sound vibration of the present utility model, including an LED module and a frame (not shown in the figure). The LED module is fixedly connected to the frame. The LED module includes an LED lamp board and a bottom case 1. The bottom case 1 is provided with positioning posts 2. The positioning posts 2 include a buffer structure 3. The buffer structure 3 is arranged on the positioning posts 2 and surrounds the positioning posts 2. Specifically, the buffer structure is a silicone rubber ring. The silicone rubber ring is sleeved on the top of the positioning post. The number of the silicone rubber rings is at least two. The positioning posts are arranged around the bottom case.
[0018] The purpose of the present invention is to solve the problems of module loosening and displacement caused by environmental vibration of the LED module. After adding 2 silicone rubber rings to the positioning posts respectively, because of its annular structure, the accuracy is guaranteed. At the same time, when the module vibrates, the silicone rubber ring deforms and compresses, which will absorb the energy generated by vibration horizontally, ensure the stability in the vibration environment, and generate resistance longitudinally to prevent the module from loosening. Depending on the actual situation, the number of positioning posts and the number of silicone rubber rings on a single positioning post can be increased.
[0019] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0020] It should be noted that the description and drawings of the present utility model give the preferred embodiments of the present utility model. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments are not additional limitations to the content of the present utility model. The purpose of providing these embodiments is to make the understanding of the disclosed content of the present utility model more thorough and comprehensive. Further, the above technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as the scope described in the specification of the present utility model. Furthermore, for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all these improvements and changes should fall within the protection scope of the appended claims of the present utility model.
