Description
Technical field
The utility model is related to LCD TV display technology field, especially a kind of light guide board fixing structure.
Background technology
In current LCD TV industry, TV module optics material is generally by reflector plate, light guide plate, diaphragm, lamp bar
It constitutes.And light guide plate 11 is because its special optical effect and material expand with heat and contract with cold that its existing fixed form of characteristic exists and much asks
Topic, to prevent top after its expansion from arriving lamp bar, general to do notch 12 using light guide plate 11, backboard 13 does location structure 14 and is inserted into notch
The displacement and expansion of 12 limitation light guide plates 11, as shown in Figure 1.But such mode causes light guide plate cost to increase, and make machinery
Slight crack easily occurs for notch when experiment, and it is bad to generate visual effect.
Utility model content
The utility model provides a kind of light guide board fixing structure, and fixing assembling mode is simple, and it is reliable can to effectively improve product
Property.
The utility model specifically adopts the following technical scheme that realization：
A kind of light guide board fixing structure, for the light guide plate of fixed support LCD TV backlight module, the backlight module
It is stacked by backboard, optical diaphragm, lower center, liquid-crystalline glasses, front frame, radiator, light bar and light guide plate, the fixed structure
Including structural body, assembly card slot, elastic arm buckle and fitting surface, the assembly card slot is assemblied in the L-type flanging of the radiator
On, the radiator offers pilot hole, and the elastic arm buckle is fixed in the pilot hole, is led described in the fitting surface support
The incident side of tabula rasa.
Preferably, the fixed structure is an integral molding structure.
Preferably, the integrally formed fixed structure is using plastic cement material or ceramic material or metal material.
Preferably, being equipped with limit rubber strip between the non-light incidence side of the light guide plate and the light bar.
Light guide board fixing structure provided by the utility model, advantage are：Processing is simple, saves component costs；
It is effectively improved light guide plate and light bar light mixing distance precision, ensures optical effect；Improve the positioning of light guide plate incident side and do not hit lamp, it is ensured that
The safety of light bar in limit experiment.
Description of the drawings
Fig. 1 is the assembling schematic diagram of the light guide plate of the prior art；
Fig. 2 is the stereogram of the utility model fixed structure；
Fig. 3 is the assembling schematic diagram of the utility model fixed structure；
Fig. 4 is another assembling schematic diagram of the utility model fixed structure.
Specific implementation mode
To further illustrate that each embodiment, the utility model are provided with attached drawing.These attached drawings are in the utility model discloses
A part for appearance mainly to illustrate embodiment, and can coordinate the associated description of specification to explain that the running of embodiment is former
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As shown in Figure 2,3, 4, a kind of light guide board fixing structure 20 provided in this embodiment, for fixed support LCD TV
The light guide plate 21 of backlight module, the backlight module by backboard 22, optical diaphragm, lower center, liquid-crystalline glasses, front frame, radiator 23,
Light bar 24 and light guide plate 21 stack, wherein fixed structure 20 includes structural body 201, assembly card slot 202, elastic arm buckle
203 and fitting surface 204, assembly card slot 202 is assemblied on the L-type flanging 231 of radiator 23, and radiator 23 offers pilot hole
232, elastic arm buckle 203 is fixed in pilot hole 232, and fitting surface 204 supports the incident side of light guide plate 21, and backboard 22 and is dissipated
The position of corresponding assembly fixed structure 20 also needs to setting groove and carries out keeping away position on hot device 23, in order to avoid interferometric optical element.
The fixed structure of the application is an integral molding structure, material may be selected plastic cement or ceramics or metal etc. it is any in.It leads
It is equipped with several limit rubber strips 25 between the non-light incidence side and light bar 24 of tabula rasa 21, is expanded in the case of 21 high temperature and humidity of light guide plate
Compression limit rubber strip 25, not will produce the phenomenon that expansion holds light bar 24.And 20 size of fixed structure of the application is accurate,
It can be very good the light mixing distance between control light guide plate 21 and light bar 24；Another light guide plate 21 can do rectangular configuration, and saving is led
21 component processing cost of tabula rasa.And this fixing assembling mode is simple, can effectively improve product reliability.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art answers
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
