Abstract

The invention relates to a backlight module and an assembling structure thereof, wherein the assembling structure of the backlight module comprises a first part and a second part, the first part comprises a first positioning part, the second part comprises a second positioning part and a free end, the second positioning part is positioned relative to the first positioning part, the free end is arranged on the second positioning part, and when the first part is combined with the second part, the second positioning part is mutually clamped with the first positioning part.

Description

Backlight module and package assembly thereof

Technical field

The present invention relates to a kind of backlight module and package assembly thereof.

Background technology

With reference to Fig. 1, known backlight module 10 includes upper ledge 11 and lower frame 12, is drilled with screw hole 13,14 on upper ledge 11 and lower frame 12 respectively, and by screw 15 upper ledge 11 and lower frame 12 is locked mutually.Because lock screw 15 is quite lost time and cost, so how to improve the efficient of assembling backlight module, is the problem to be solved in the present invention.

Summary of the invention

In order to improve above-mentioned shortcoming, the invention provides a kind of backlight module and package assembly thereof, include one first parts and one second parts, first parts comprise one first location division, and second parts comprise one second location division and a free end, and second position point is in the position with respect to first location division, and free end is located on second location division, when first parts combined with second parts, second location division engaged mutually with first location division.

In order to make above-mentioned and other purpose of the present invention, feature and advantage can more obvious easy to understand, below especially exemplified by concrete preferred embodiment, and conjunction with figs. elaborates.

Fig. 3 A is the enlarged drawing of Fig. 2;

Fig. 3 B is the sectional view of B-B profile line among Fig. 3 A;

Fig. 4 is the combine synoptic diagram of backlight module first parts of the present invention with second parts;

Fig. 5 A-5C is the separating step figure of backlight module first parts of the present invention and second parts.

Embodiment

With reference to Fig. 2, backlight module 20 of the present invention comprises first parts 21 (lower frame) and second parts 22 (upper ledge), and first parts 21 need mutually combine with second parts 22 and fix the assembly working that just can finish backlight module 20.

With reference to Fig. 3 A, 3B, wherein Fig. 3 B is the sectional view of Fig. 3 A section line B-B.First parts 21 comprise first location division 211, and second parts 22 comprise second location division 221, through hole 225, free end 222 and stiff end 224.Second location division, 221 parts are positioned at through hole 225, be connected with second parts 22 by stiff end 224, and be oppositely arranged with the position of first location division 211, and free end 222 is extended out by stiff end 224, and second location division 221 includes projection 223, and in an embodiment of the present invention, first location division 211 can be the hole, hole by projection 223 and first location division 211 is chimeric mutually, and first location division 211 is engaged mutually with second location division 221.In addition, also comprise stressed district 226 on the free end 222, the assembler is convenient to free end 222 application of forces in stressed district 226.

With reference to Fig. 4,5A-5C, wherein, Fig. 4 is first parts 21 and the figure that combines of second parts 22, at this moment, the position of first parts 21 and second parts 22 is first state, promptly engage so that mutually combine with first location division 211, and Fig. 5 A is the sectional view of A-A profile line among Fig. 4 by second location division 221.

When first parts 21 will separate with second parts 22, earlier to stressed district 226 application of forces on second location division 221, the free end 222 of second location division 221 is rotated with arrow a direction, and the projection 223 on first location division 211 and second location division 221 breaks away from, shown in Fig. 5 B.At this moment, the position of first parts 21 and second parts 22 is second state.At last, along arrow C, C ' the direction application of force, first parts 21 and second parts 22 are broken away from mutually, the result is shown in Fig. 5 C.Otherwise, when first parts 21 will combine fixedly with second parts 22, then show reverse procedure greatly and carry out, below repeat no more.It should be noted, second location division 221 of the present invention can have elasticity, during at ordinary times not to second location division, 221 application of forces, second location division 221 and second parts 22 are roughly in the same plane, and to second location division, 221 application of forces time, make first parts 21 and second parts 22 in conjunction with or separate after, promptly remove the application of force after, second location division 221 is returned to roughly the position in the same plane with second parts 22 immediately.

The invention provides simple and structure fast,, increase production efficiency relatively to reduce the built-up time of backlight module than known backlit module assembling.

Though the present invention discloses with preferred embodiment; but it is not that any those skilled in the art is not breaking away from design of the present invention and scope in order to qualification the present invention; still can make some and change and retouching, so protection scope of the present invention is defined with accompanying Claim.
