According to the fixing structure of the LED liquid crystal display assembly, a limiting structure is adopted, such that no or less screws or double faced adhesive tapes are needed for mounting the lamp strip, fixing reliability and smoothness of the circuit board are ensured, the fixing structure is easy and convenient to assemble and disassemble, safe and reliable, the assembling efficiency is raised, the repair and maintenance costs are reduced, and the fixing structure is applicable to LED liquid crystal display television.
Description
Technical field
The utility model relates to a kind of LED liquid crystal display, especially relates to a kind of fixed sturcture of LED liquid crystal display assembly.
Background technology
LED lamp bar provides backlight for the LED liquid crystal display, and LED lamp bar and the circuit board that is positioned at liquid crystal display inside are the significant components of LED liquid crystal display.In the straight-down negative LED liquid crystal display, generally adopt the screw connection or adopt the bonding mode of double-sided tape that the circuit board of LED lamp bar and liquid crystal display inside is fixed at present.Because the lamp bar quantity of straight-down negative LED liquid crystal display is more, and the fixed form of above-mentioned two kinds of LED lamp bars all needs a large amount of screws and double faced adhesive tape to fix in installing, and manual assembly cost and Material Cost are higher; Often can occur the situation that screw gets loose and double faced adhesive tape lost efficacy after fixing, when changeing the lamp bar, very easily damage the lamp bar, cause the lamp bar to scrap, production efficiency and after-sales service are brought very large impact.
The utility model content
Technical problem to be solved in the utility model is to overcome in the prior art screw or double faced adhesive tape quantity is many and fixing poor reliability shortcoming, and a kind of fixed sturcture of LED liquid crystal display assembly is provided.
The technical scheme that its technical matters that solves the utility model adopts is: the fixed sturcture of LED liquid crystal display assembly, comprise LED lamp bar and circuit board, and LED lamp bar comprises substrate and LED lamp, and LED lamp bar is provided with projection, and circuit board is provided with the draw-in groove that is complementary with projection.
Concrete, described projection is at least two groups.
Further, described projection is that the interval arranges.
Concrete, described projection comprises limiting section and connecting portion, the upper surface of described limiting section is parallel to the upper surface of substrate.
Preferably, described projection is T shape card column.
As the preferred version of technique scheme, the thickness of described projection is greater than the thickness of LED lamp.
The beneficial effects of the utility model are: the fixed sturcture of this LED liquid crystal display assembly has adopted position limiting structure, uses no or little screw or double faced adhesive tape when the lamp bar is installed, and guarantees fixing reliability and the planarization of circuit board, dismounting is easy, safe and reliable, improve efficiency of assembling, reduce and reprocess maintenance cost.The utility model is applicable to the LED LCD TV.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment lamp bar;
Fig. 2 is the structural representation of the utility model embodiment circuit board;
Wherein, 1 is the LED lamp, and 2 is substrate, and 3 is T shape card column, and 11 is circuit board, and 12 is draw-in groove.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The fixed sturcture of LED liquid crystal display assembly of the present utility model comprises LED lamp bar and circuit board 11, and LED lamp bar comprises substrate 2 and LED lamp 1, and LED lamp bar is provided with projection, and circuit board 11 is provided with the draw-in groove 12 that is complementary with projection.
Embodiment
As shown in Figure 1, the projection in this example is T shape card column 3, comprises limiting section and connecting portion, and the upper surface of limiting section is parallel to the upper surface of substrate 2, and better fixed light bar and circuit board 11 are so that lamp bar and circuit board 11 keeping parallelism states.
As shown in Figure 2, the draw-in groove 12 in this example is the Long Circle groove structure, and there are respectively two columniform draw-in grooves at the two ends of this structure, and one of them is slightly larger than the connecting portion of T shape card column 3, is the placement end of draw-in groove; The connecting portion of another cylindrical draw-in groove and T shape card column 3 big or small suitable is the stiff end of draw-in groove.Projection is at least two groups and interval setting, can effectively reduce the screw number of fixing circuit board and the planarization of assurance circuit board.In addition, the shape of draw-in groove also can be other shapes such as square, rhombus.
During concrete the installation, first T-shaped card column 3 being inserted draw-in grooves 12 right-hand members is the placement end of draw-in groove 12, and then sliding into draw-in groove 12 left ends along the Long Circle draw-in groove is that the stiff end of draw-in groove 12 is fixed.LED lamp bar can effectively be fixed in the draw-in groove 12 and can guarantee the planarizations of lamp bar, for the long lamp bar circuit board of length, separated by a distance a T-shaped card column 3 is set, and can effectively reduce the screw number of fixing circuit board and guarantee the planarization of circuit board.
For alleviating the assembling pressure in when assembling, the thickness of T shape card column 3 is greater than the thickness of LED lamp 1, and the LED lamp 1 that staggers of the deformed region in the time of can making assembling prevents that other devices from contacting with the LED lamp, protects LED lamp 1, is more convenient for assembling, and can improve packaging efficiency.
T shape card column 3 is an integral body with bottom parts as plastic rear cover in this example, in addition, and also can be separated among other embodiment.
