The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Fig. 7 to Figure 13 is first embodiment of the present invention's module backlight.
The present invention discloses a kind of module backlight; It comprises: combine chase 10, glue frame 20 and backboard 30; Shown in Figure 7 is the partial schematic diagram of backboard, is provided with some boss 31 around the backboard 30, shown in boss 31 comprise first boss 311 that is positioned on backboard 30 sides and be positioned at second boss 312 on first boss 311; The floor space of second boss 312 is littler than the floor space of first boss 311, and first boss 311 and second boss 312 are trapezoidal shape.
Shown in Figure 8 is the partial schematic diagram of glue frame; Be provided with some first perforates 21 around the glue frame 20; Be provided with second perforate 22 and the 3rd perforate 23 in the both sides of first perforate 21; Said first perforate 21 connects with glue frame 20 bottoms, and is provided with the first long limit 211 that is connected with glue frame 20 bottoms in the bottom of first perforate 21 and the middle place on 212, the first long limits 211, the second long limit and the second length limit 212 is the groove that connects with first perforate 21.
Fig. 9 is said to be the schematic layout pattern of chase, also is provided with some flutings 11 around the chase 10.
Figure 10 and Figure 11 are the sketch mapes of backboard of the present invention and the combination of glue frame; After the boss 31 of backboard 30 is passed in first perforate 21 of glue frame 20; First perforate 21 be enclosed within first boss 311 around, and first rectangular 211 and second rectangular 212 being connected on first boss, 311 sides of first perforate 21 is by the restriction that is clasped of first perforate 21 and first boss 311; Can glue frame 20 be fixed on the backboard 30, thus thickness (Z) the direction displacement of restriction glue frame 20.
Figure 12 and Figure 13 are the sketch mapes of backboard of the present invention and chase combination; After backboard 30 and glue frame 20 are fixed, again chase 10 is fixed on the backboard 30, the fluting 11 of chase 10 passes second boss 312 of backboard 30; Thereby chase 10 is fixed on the backboard 30; By the restriction that is clasped of fluting 11 and second boss 312, can chase 10 be fixed on the backboard 30, thus thickness (Z) the direction displacement of restriction chase 10.
Figure 14 to Figure 16 is the second embodiment of the present invention; With above-mentioned first embodiment difference be; The side of first boss, 311 ` of backboard 30 ` is provided with a groove 313 `; First rectangular 211 and second rectangular 212 of said glue frame 20 is connected to the both sides of groove 313 `, helps like this on first boss, 311 ` that glue frame 20 is fixed on backboard 30 `, by the restriction that is clasped of first perforate 21 and first boss 311; Can glue frame 20 be fixed on the backboard 30, thus thickness (Z) the direction displacement of restriction glue frame 20.
Like Figure 16 is the sketch map of second embodiment backboard of the present invention and chase combination; After backboard 30 and glue frame 20 are fixed; Chase 10 is fixed on the backboard 30, the fluting 11 of chase 10 passes second boss 312 of backboard 30, thereby chase 10 is fixed on the backboard 30 again; The restriction that is clasped by fluting 11 and second boss 312; Can chase 10 be fixed on the backboard 30, thus thickness (Z) the direction displacement of restriction chase 10, and the compound mode of present embodiment backboard and chase is basically the same as those in the first embodiment.
Existing module glue frame backlight and backboard closed position, different with chase with the backboard closed position, cause backboard sidewall upper clamping hook number of structures numerous, and cost is also higher; Can improve the problems referred to above though reduce backplane card hooking structure quantity, will cause the product structure reliability not good, produce problems; The present invention's module backlight can reduce backboard sidewall upper clamping hook number of structures, and reduces cost, and has good production reliability and reliability.
