Abstract
The utility model is suitable for the field of backlight module group, and provides a back board structure of backlight module group. The back board comprises an upper back board, a lower back board which is matched with the upper back board and a side back board which is correspondingly clamped and connected with the lower back board, wherein the lower back board and the side back board can achieve clamped connection through a convex portion and a holding groove which are arranged on the lower back board and the side back board. When a light source in the backlight module group needs taking out, the holding groove or the convex portion of the side back board and the convex portion or the holding groove of the lower back board only need firstly releasing, and then, the lateral side board is drawn out along the bottom of the lower back board, thereby taking out the light source which is arranged on the side back board. Compared with the prior, the light source can be conveniently takenout by the back board structure without disassembling the whole backlight module group, and the backlight module group and a liquid crystal display device can not be polluted by foreign matters.
Description
Technical field
The utility model belongs to module backlight field, relates in particular to a kind of back board structure of module backlight.
Background technology
The back board structure of module backlight comprises backboard and the following backboard that cooperates with described upward backboard, and described going up between backboard and the following backboard is provided with elements such as light source, LGP, reflector plate, diffusion sheet and brightening piece.Take out the light source in the module backlight if desired, then need to pull down backboard and following backboard, the light source of module backlight could be taken out, operation is trouble very, but also can cause foreign substance pollution to module backlight.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of back board structure of module backlight, and not needing to disassemble entire aphototropism mould can take out the light source on the paranotum easily.
The utility model is achieved in that a kind of back board structure of module backlight, comprise backboard, with described go up following backboard that backboard cooperates and with the described paranotum of the corresponding engagement connection of backboard down.
Particularly, described down backboard is provided with at least one protuberance, offer on the described paranotum with described backboard down on the storage tank of the corresponding engaging of protuberance.
Particularly, described down backboard is provided with at least one storage tank, offer on the described paranotum with described backboard down on the protuberance of the corresponding engaging of storage tank.
Particularly, described down backboard is provided with at least one protuberance and at least one storage tank, offer on the described paranotum with described backboard down on storage tank, the protuberance of the corresponding engaging of protuberance, storage tank.
More specifically, described storage tank is the hole through described paranotum.
More specifically, also be provided with the protuberance that is connected with the light source of module backlight on the described paranotum.
During light source in needs take out module backlight, only need earlier the storage tank of paranotum or the protuberance on protuberance and the play backboard or storage tank are broken away from, the bottom of backboard detaches out paranotum under the edge then, can take out the light source of being located on the paranotum; Compared with prior art, the utility model does not need entire aphototropism mould is disassembled, and just can easily light source be taken out, and can not cause foreign substance pollution to module backlight and liquid crystal indicator.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment one
As Fig. 1～shown in Figure 5, the back board structure of the module backlight that the utility model embodiment provides, comprise the backboard (not shown), with the described following backboard 1 that backboard cooperates, the paranotum 2 that is connected with described following backboard 1 gone up.Described backboard 1 down is provided with at least one protuberance 11; Described protuberance 11 evenly is located on the described backboard 1 down; Offer on the described paranotum 2 with described down backboard 1 on the storage tank 21 of protuberance 11 corresponding engagings, thereby realize being connected of backboard 1 and paranotum 2; Described storage tank 21 can select to run through the hole of described paranotum 2, and the shape of the protuberance 11 of the shape of this hole and following backboard 1 is complementary, and can be shapes such as square, circle.
Unlike the prior art, the utility model is that the light source (not shown) of module backlight is located on the paranotum 2, and light source is connected with protuberance 22 on the paranotum 2.During light source in needs take out module backlight, only need earlier the hole of paranotum 2 is broken away from play backboard 1 bottom lug 11, then along under the bottom of backboard 1 detach out paranotum 2, can take out the light source on the paranotum 2.
Compared with prior art, the utility model does not need entire aphototropism mould is disassembled, and just can easily light source be taken out, and can not cause foreign substance pollution to module backlight and liquid crystal indicator.
Embodiment two
Present embodiment two is the same with the principle of embodiment one, its difference part only be storage tank and protuberance to offer the position different, be specially: described down backboard is provided with at least one storage tank, offer on the described paranotum with described backboard down on the protuberance of the corresponding engaging of storage tank.
Embodiment three
Present embodiment three is the same with the principle of embodiment one, its difference part also only be storage tank and protuberance to offer the position different, be specially: described down backboard is provided with at least one protuberance and at least one storage tank, offer on the described paranotum with described backboard down on storage tank, the protuberance of the corresponding engaging of protuberance, storage tank.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
