Abstract
A large-screen display screen unit includes a shell (1), a display board and a driving control plate (3). The shell (1) is a box made by plastic rubber and is provided with at least one exhaust port (5) connected with an exhaust fan (7), which is also provided with at least one air supply outlet (6) connected with a blower (8). The plastic shell (1) is provided with static electricity proof, lightning proof, anticorrosion and light weight. The utility model uses the exhaust fan (7) and the blower (8) to intently exhaust and supply air, which reduces the manufacture cost and simplifies the structure. If the blower (8) is added with an air filtration device to keep the inner shell (1) clean and dry, so that the utility model can ensure the working reliability of the arranged electrical components and prolong the service life of the electrical components.
Description
Technical field the utility model relates to electronic display unit, particularly the display screen unit of giant-screen.
Background technology is the display unit on big screen display screen at present, all is to use metal shell.The display unit of this structure is heavier, erecting frame is required high, and housing itself can not electrostatic prevention, thunderbolt and corrosion.Because housing is shaped or welding forming by metallic plate punching,, make troubles or distortion or the like in use to assembly working so precision is not high.Because each display unit all needs to be equipped with at least one fan, so both increased the complicacy of system, also increased simultaneously manufacturing cost, and owing to need suck air in the housing upper shed, so just airborne moisture, impurity and objectionable impurities are drawn into enclosure interior, the electric component that infringement is inner reduces its security and serviceable life.
The summary of the invention the purpose of this utility model is for fear of above-mentioned the deficiencies in the prior art, for the user provide a kind of in light weight, protection effect good, simple in structure and big screen display screen unit that cost is low.
The utility model comes specific implementation by implementing following technical scheme, the big screen display screen unit that this programme is designed, comprise housing, the display board of being made up of a plurality of displaying blocks is fixed on the one side of housing by substrate, and the drive controlling plate is fixed on the another side of housing.Described housing is the box-like body of being made by plastic material, and described housing is provided with at least one suction opeing, and this suction opeing links to each other with air exhauster by airduct, also is provided with at least one air outlet on the described housing, and this air outlet links to each other with pressure fan by airduct.This programme is a plastic material with case design, can electrostatic prevention, thunderbolt and corrosion, alleviate the weight of this display unit simultaneously.Because by injection molded, so the precision height, it is easy and durable in use to assemble.Cancelled fan among the design, and used air exhauster instead and pressure fan is concentrated exhausting and air-supply, both reduced manufacturing cost, also simplified the structure simultaneously.And can on pressure fan, increase air filter, and keep cleaning and drying in the housing, guarantee the reliability of its internal electric parts work and the serviceable life that prolongs electric component.
Because the utility model is implemented technique scheme, so, have in light weight, protection effect good, simple in structure and characteristics that cost is low.
Description of drawings
Fig. 1 is the main cross-sectional schematic of looking in the utility model big screen display screen unit.
Fig. 2 is that synoptic diagram is looked on the right side, the utility model big screen display screen unit.
Further describe the most preferred embodiment of the utility model below in conjunction with accompanying drawing.
Embodiment as can be seen from Figure 1, this big screen display screen unit comprises housing 1, the display board 2 that contains displaying block 22 and substrate 21 is fixed on the one side of housing 1 by substrate 21, and drive controlling plate 3 is fixed on the another side of housing 1.Described housing 1 is the box-like body of being made by plastic material, described housing 1 is provided with at least one suction opeing 5, this suction opeing links to each other with air exhauster 7 by airduct 51, also is provided with at least one air outlet 6 on the described housing 1, and this air outlet links to each other with pressure fan 8 by airduct 61.The housing 1 of plastic cement material can electrostatic prevention, thunderbolt and corrosion, alleviates the weight of this display unit simultaneously.Because by injection molded, so the precision height, it is easy and durable in use to assemble.Cancelled fan among the design, and used air exhauster 7 instead and pressure fan 8 is concentrated exhausting and air-supply, both reduced manufacturing cost, also simplified the structure simultaneously.And can on pressure fan 8, increase air filter, and keep cleaning and drying in the housing 1, guarantee the reliability of its internal electric parts work and the serviceable life that prolongs electric component.
As can be seen from Figure 1,, on suction opeing 5 and air outlet 6, connecting pipe joint 52 and 62 are housed respectively in order to make the firm more of airduct connection and to improve the effect of taking out, blowing, affixed with airduct 51 and 61 respectively.
From Fig. 1 and Fig. 2, can find out, between described displaying block 22 and the housing 1, be provided with sealant 4 between drive controlling plate 3 and the housing 1.Sealant 4 can prevent that sealing, impurity and harmful gas enter in the housing 1, guarantee the safety of internal electric parts, and sealant 4 can be selected waterproof fluid sealant or resilient sealing joint strip for use.
