Currently, there are plug-in (LAMP) LED outdoor display and surface mount (SMD) LED outdoor screen display module and cabinet structure is basically as follows: display module as plastic molding; Case for the sheet metal cabinet. Both the waterproof apron assembled by fastening screws for the display cabinet, and then assembled into the display.

Existing Outdoor SMD display the basic use of plug-in display plastic shell and sheet metal enclosures as SMD LED tube thickness far thinner than plug-in LED (SMD approximately 2. 5mm; LAMP about 7mm), so that bring waterproof SMD outdoor screen cooling and difficult issues, so that the existing SMD outdoor screen appears blind spot rate, optical parameters unstable operation and other defects. Meanwhile, SMD outdoor screen in high density as the main product development direction, but because of the existing plastic shell and sheet metal machining error box widespread in 0. 5mm or more, seriously restricting screen density and accuracy, so difficult to significantly improve the quality of LED screens . The deficiencies of the prior art for improvement.

目前，已有插件式（LAMP) LED户外显示屏和表面贴装式（SMD) LED户外显示屏的显 示模组和箱体结构基本上为：显示模组为塑胶件成型；箱体为板金箱体。二者由防水胶圈 经紧固螺丝组装为显示箱体，进而组装为显示屏。

现有的户外SMD显示屏基本采用插件式显示屏的胶壳和板金箱体，由于SMD发光 管厚度远薄于插件式发光管（SMD约2. 5mm ；LAMP约7mm)，这样就带来SMD户外屏幕散热和 防水困难问题，以至于现有的SMD户外屏幕出现盲点率高、光电参数运行不稳定等缺陷。同 时，SMD户外屏以高密度为主要产品发展方向，但由于，现有的胶壳和板金箱体加工误差普 遍在0. 5mm以上，严重制约屏幕密度及精度，使LED屏幕品质难以大幅度提升。所述现有技 术的缺陷值得改进。

This utility model aims to address the above technical defects, provide a surface mount LED outdoor display screen integrated display module box structure, the surface-mount LED outdoor display cabinet integrated display module structure will make SMD outdoor screen in high-density, thin, waterproof, heat and other aspects were improved optical parameters also can be improved.

 本实用新型的目的在于针对上述技术缺陷，提供一种表面贴装式LED户外显示屏 一体式显示模组箱体结构，该表面贴装式LED户外显示屏一体式显示模组箱体结构将使得 SMD户外屏在高密度、轻薄型、防水、散热等方面均得到改善，光电参数亦得以提升。

The technical solution of the utility model are as follows: a surface-mount LED outdoor display screen integrated display module box structure, including SMD, PCB board, box, SMD soldered on PCB and located in outside the box, characterized in that: said housing comprises aluminum case cooling structure, aluminum mask, the aluminum casing rear cover, said welded SMD PCB board located in the aluminum mask and aluminum heat sink structure of the tank aluminum casing and cement in between the heat sink structure, the structure of the aluminum heat sink cabinet with aluminum mask, aluminum cabinet rear cover connection.

 本实用新型的技术方案如下所述：一种表面贴装式LED户外显示屏一体式显示模 组箱体结构，包括SMD、PCB板、箱体，SMD焊接在PCB板上并设于箱体外，其特征在于：所 述箱体包括铝箱体散热结构件、铝面罩、铝箱体后盖板，所述焊接有SMD的PCB板设于铝面 罩和铝箱体散热结构件之间并粘固在铝箱体散热结构件上，所述铝箱体散热结构件与铝面 罩、铝箱体后盖板连接。

 According to the above structure of the utility model, and its beneficial effects in that: The utility model soldered SMD PCB board with aluminum box set for the integration of the whole cabinet, display board for each interval only SMD PCB board cooling fins and the box is connected to the radiator tank and a bearing that is, spatial separation structure, to ensure that each of the heat generated only SMD thermal shortest path, the minimum conduction time and circulated out resistance; with full aluminum mold manufacturing structural parts, completely out of plastic parts, sheet metal cabinet for assembly precision limitations assembly precision from the original 0. 5-lmm errors, reduced to 0.
