Description
Technical field
The utility model belongs to LCD screen technical field, specifically a kind of shockproof backlight module.
Background technique
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.Backlight module has brightness high, and the service life is long, shines the features such as uniform.Mainly there are tri- kinds of EL, CCFL and LED back 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 mould group, can because shining uniformly
For use as ultrathin backlight mould group, thus it is fast-developing.Backlight module inevitably encounters vibration, LED during transportation
Light source board can usually be damaged because of vibration.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of shockproof backlight module for the deficiency in current technology,
While with high leakproofness, possesses good heat dissipation performance, and structure is simple, be easily assembled to.
Technical solution: to achieve the above object, the utility model provides a kind of shockproof backlight module, including box body, described
One side opening of box body, box body inside are disposed with LED light source board, diffusion sheet, optical film assembly and screen from ground to opening
Curtain；Adhesive board is provided between the LED light source board and box body bottom, the adhesive board is made of soft rubber material, bonding
Plate two sides are coated with binder and bond respectively with box body inside bottom surface and the LED light source board back side；The every side of LED light source board
While be evenly arranged at least two positioning column, the positioning column is prominent cylindrical body, box body medial surface corresponding position be provided with
The corresponding positioning column of LED light source board side positioning column, corresponding box body side positioning column and LED light source board side positioning column
On be socketed with 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 and 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 adhesive board is with a thickness of 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.
The utility model has the advantages that a kind of shockproof backlight module described in the utility model, LED light source board and box body inside bottom surface and
Side is connected by the rubber material with buffering effect, in backlight module transportational process, encounters vibration, the vibration warp of box body
The buffering for crossing adhesive board and bumper post is transmitted at LED light source board and weakens significantly.Meanwhile when encountering high frequency time vibration, due to slow
The presence of column and adhesive board is rushed, the frequency and amplitude substantially reduce when vibration is transmitted to LED light source board, prevent high frequency time vibration pair
It is destroyed caused by circuit and LED light in LED light source board.
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 use is safe, by test of many times, its hardness controlled in Shore A hardness 55-60,
Damping performance is best.
A kind of shockproof backlight module, structure is simple, while installation and removal are very simple, can greatly reduce backlight
The vibration that LED light source board is subject in mould group transportational process, prevents LED light source board from damaging during transportation.
