The present invention discloses a back light module and a liquid crystal display (LCD) device. A back light module comprises a light guide plate; both sides of the light guide plate are respectively provided with multiple notches; the back light module is provided with riveted nut studs in the notches; and buffer parts are arranged between the riveted nut studs and the notches. In the present invention, because buffer material such as silicone, rubber and the like is arranged between each notch and each riveted nut stud of light guide plate, the buffer material can provide effective buffer function when the light guide plat is affected by impact force to avoid damage caused by direct impact between the light guide plate and the riveted nut studs. Thus, low cost is achieved because of simple process and economic material. In addition, the tight contact of the light guide plate and the riveted nut stud is kept by the buffer part, and the shake of the light guide plate is avoided.
1, A back light module, comprising:
2, The back light module of claim 1, wherein each said buffer part is a buffer sleeve, and said buffer sleeve is sheathed with each said riveting bolt.
3, The back light module of claim 2, wherein said buffer sleeve is made of silicone, rubber or foam material.
4, The back light module of claim 2, wherein each said riveted nut stud is provided with a groove;
5, The back light module of claim 4, wherein said groove surrounds the whole surface of said riveted nut stud;
6, The back light module of claim 2, wherein the thickness of said buffer sleeve is not less than 1.2 mm.
7, The back light module of claim 1, wherein each said buffer part is a buffer pad, and said buffer pads are arranged on the inner surfaces of the notches on both sides of said light guide plate.
8, The back light module of claim 7, wherein said buffer pad is made of elastic rubber.
9, The back light module of claim 1, wherein elastic rubber or foam material is filled in all the gaps between said riveted nut studs and said notches to form said buffer parts.
10, The back light module of claim 9, wherein each said buffer part is formed through injection molding by an adhesive dispenser.
11, A liquid crystal display (LCD) device, comprising the back light module of claim 1, said back light module comprises a light guide plate;
12, The LCD device of claim 11, wherein each said buffer part is a buffer sleeve, and said buffer sleeve is sheathed with each said riveting bolt.
13, The LCD device of claim 12, wherein said buffer sleeve is made of silicone, rubber or foam material.
14, The LCD device of claim 12, wherein each said riveted nut stud is provided with a groove;
15, The LCD device of claim 14, wherein said groove surrounds the whole surface of said riveted nut stud;
16, The LCD device of claim 12, wherein the thickness of said buffer sleeve is not less than 1.2 mm.
17, The LCD device of claim 11, wherein each said buffer part is a buffer pad, and said buffer pads are arranged on the inner surfaces of the notches on both sides of said light guide plate.
18, The LCD device of claim 17, wherein said buffer pad is made of elastic rubber.
19, The LCD device of claim 11, wherein elastic rubber or foam material is filled in all the gaps between said riveted nut studs and said notches to form said buffer parts.
20, The LCD device of claim 19, wherein each said buffer part is formed through injection molding by an adhesive dispenser.
