Description
Technical field
The invention belongs to LCD screen technical field, specifically a kind of shockproof backlight module.
Background technology
The effect of backlight module is to provide the light source of LCD panel.Mainly by light source, light guide plate, optical film piece, plastic frame
Deng composition.There is backlight module brightness height, long lifespan to shine the features such as uniform.Mainly there are tri- kinds of back ofs the body of EL, CCFL and LED at present
Optical mode set type is then divided into side-light type and straight-down negative according to distribution of light sources position difference.LED backlight module, can because shining uniformly
For use as ultrathin backlight module, thus it is fast-developing.Backlight module inevitably encounters vibrations, LED in transportational process
Light source board can usually be damaged because of vibrations.
Invention content
Goal of the invention：The purpose of the present invention is for the deficiency in current technology, provide a kind of shockproof backlight module, have
While high leakproofness, possesses good heat dissipation performance, and simple in structure, be easily assembled to.
Technical solution：To achieve the above object, the present invention provides a kind of shockproof backlight module, including box body, the box body
One side opening, box body inside are disposed with LED light source board, diffusion sheet, optical film assembly and screen from ground to opening；Institute
It states and is provided with adhesive board between LED light source board and box body bottom, the adhesive board is made of soft rubber material, adhesive board both sides
Face is coated with binder and is bonded respectively with box body inside bottom surface and the LED light source board back side；The LED light source board is uniform per side
It is provided at least two positioning column, the positioning column is prominent cylinder, and box body medial surface corresponding position is provided with and LED light source
The corresponding positioning column of plate side positioning column, corresponding box body side positioning column are socketed on the positioning column of LED light source board side
Have a bumper post, the bumper post is rubber material, and bumper post is the cylindrical structure that both ends are equipped with blind hole, bumper post both ends blind hole with
Positioning column tight fit.
As a kind of improvement of this programme, the adhesive board is made of silica gel or butadiene rubber.
As a kind of improvement of this programme, the cohesive plate thickness is 5-10mm.
As a kind of improvement of this programme, the bumper post is made of silica gel or butadiene rubber.
As a kind of improvement of this programme, the adhesive board and bumper post hardness are Shore A hardness 55-60.
Advantageous effect：A kind of shockproof backlight module of the present invention, LED light source board and box body inside bottom surface and side
It is connected by the rubber material with buffering effect, in backlight module transportational process, encounters vibrations, the vibrations of box body are by viscous
The buffering of knot tying and bumper post is transmitted at LED light source board and weakens significantly.Meanwhile when encountering high frequency time vibrations, due to bumper post
With the presence of adhesive board, the frequency and amplitude substantially reduce when vibrations are transmitted to LED light source board, prevent high frequency time vibrations to LED light
It is destroyed caused by circuit and LED light in source plate.
Adhesive board and buffering column material are silica gel or butadiene rubber, and silica gel and butadiene rubber itself have good shock absorption
Can, while property is stablized, and does not burn, and it is safe to use, by test of many times, its hardness is controlled in Shore A hardness 55-60,
Damping performance is best.
A kind of shockproof backlight module, it is simple in structure, while installation and removal are very simple, can greatly reduce backlight
The vibrations that LED light source board is subject in module transportational process, prevent LED light source board from being damaged in transportational process.
