Abstract
The utility model relates to a variable sealed information board composed of a pixel pipe under the control of an electronic circuit and a display module. The variable sealed information board is designed to use a structure, wherein, the structure is provided with an inner and an outer boxes, and the inner box is sealed. The inner box has the obvious characteristics of dust prevention, water prevention, heat insulating outer box and, ventilation. Accordingly, the variable sealed information board can normally work under any adverse weather conditions, and the display effect of the variable sealed information board is sufficiently achieved.
Description
What the present invention relates to is the super bright diode displaying field of electronic circuit control, particularly highway variable information board and highway speed(-)limit sign etc.The variable information board of case sealing in the interior outer container bilayer has dustproof, waterproof, heat insulation, the obvious characteristic of ventilating.
The existing highway variable information board all exists and is difficult to waterproof and dustproof and heat-insulating problem, and particularly hot weather sunlight direct projection temperature in chassis is higher relatively, by the extraction fan exhaust cooling, has the defective that is difficult to seal.Because blow-by, dust, rainwater just can enter unavoidably, very easily corrode electronic devices and components thereby cause short circuit, damage the phenomenon of components and parts, and make the variable information board reliability decrease, even can't use.
Purpose of the present invention, body structure to existing variable information board is improved, relate to and adopt interior outer container bilayer, interior case hermetically-sealed construction, cancelled the bad form of extraction fan cooling, possessed because of sealing is prevented dust, the obvious characteristic of waterproof, thereby ensured the reliability service of variable information board, no matter under which kind of bad weather condition, all can normally use, fully play the usefulness that variable information board shows.
The technical scheme that the present invention relates to connection position as shown in the figure, the interior outer container bilayer of forming by the interior case (12) of the outer container (7) of band window shutter (8) and sealing, the variable information board that interior case seals.
Interior case (12) back side of sealing is provided with the hermatic door (13) that O-ring seal (6) are housed, and heating radiator O-ring seal (10) and power-supply radiator (11) are equipped with in hermatic door (13) upper shed securely, and power-supply radiator (11) is gone up fixed power source (5); The positive pixel pipe (3) of interior case (12) passes through O-ring seal (2) sealing and fixing in the front of display module (4), and display module (4) back side in interior case (12) front, is formed the LED dot matrix by O-ring seal (1) sealing and fixing.Connect lead (9) and power connection.
The outer container (7) of band window shutter (8) covers interior case (12) as shown in the figure, leave certain space between interior case (12) and outer container (7), cooling air enters from outer container (7) bottom, is discharged by window shutter (8), form the natural ventilation state, interior case (12) operating ambient temperature is relatively stable.
Power supply (5) in the variable information board of case sealing in the interior outer container double-decker, dispel the heat by heating radiator (11), therefore eliminated the bad form that extraction fan air draft cooling can't seal, covering outer container (7), avoided case (12) in the sunlight direct projection in summer, the structure of case (12) sealing has played the effect to the components and parts waterproof and dustproof in particularly adopting.
The present invention does further statement to technical scheme in conjunction with the accompanying drawings:
The technical scheme that the present invention relates to has the interior case (12) of hermetically-sealed construction as shown in the figure, has the variable information board of case sealing in the interior outer container bilayer that the outer container (7) of window shutter (8) forms.
Positive design is encased inside O-ring seal (2,1) respectively and is arranged the installation site that the interior case (12) of packing into has slot, sealing and fixing by certain position by plurality of pixels pipe (3) display module (4).Display module (4) proper alignment is combined into the LED dot matrix.
The hermatic door (13) at interior case (12) back side is connected with hinging manner with interior tank shell.Have the hole that heating radiator O-ring seal (10) and power-supply radiator (11) can be installed on the hermatic door (13), the power-supply radiator (11) that will be lined with O-ring seal (10) is fixed on the hermatic door (13), power supply on power-supply radiator (11), becomes the power supply cooling system that utilizes radiator heat-dissipation by screw retention.
The peripheral sealing means of hermatic door (13) is by flanging place shown in the diagrammatic sketch I O-ring seal (6) to be housed, case (12) in the sealing when closing.
For preventing accident, by flanging shown in the figure I, rainwater etc. more can't enter interior case (12) at hermatic door (13) opening part.
For effectively preventing the hot weather periods of direct sunlight, interior case (12) outer cover outer container (7), strong daylight can't direct projection arrive interior case (12), greatly reduced the temperature rise of interior case (12), outer container (7) is because the bottom has the large tracts of land hole simultaneously, cooling air enters from bottom port, by the space between interior case (12) and outer container (7), outwards distribute from window shutter (8), air guided flowing, take away the heat that sheds by interior case (12) and because of the sunlight direct projection at the formed heat of outer container (7), avoided interior case (12) that sunlight direct projection outer container (7) causes and the atmosphere temperature rising between the outer container (7), case (12) working temperature is near normal temperature in fully guaranteeing.
Thus, in the interior outer container bilayer variable information board of case sealing can be under any adverse weather condition operate as normal.
Claims (3)
1. the variable information board of case sealing in the outer container bilayer in a kind, its double-decker by interior case (12) and outer container (7) is formed, it is characterized in that having the outer variable information board of adorning the interior case sealing of interior outer container bilayer of outer container (7) composition that has window shutter (8) of interior case (12) of hermetically-sealed construction.
2. the variable information board of case sealing in a kind of interior outer container bilayer according to claim 1, it is characterized in that, pixel pipe (3) is housed on the interior case (12), display module (4), all by the O-ring seal sealing, power supply (5) is installed on the power-supply radiator (11) for hermatic door (13) and power-supply radiator (11); Outer container (7) bottom has large tracts of land hole and window shutter (8), and outer container is heat insulation, forms the double-decker of natural ventilation cooling between interior outer container.
According to claim 1,2 described a kind of in the variable information board of case sealing in the outer container bilayers, it is characterized in that display module (4) physical dimension is a rectangle, and correspondingly on interior case (12) panel, have the rectangle mounting hole.
