BACKLIGHT MODULE AND ENGAGEMENT FITTING THEREOF, DISPLAY DEVICE USING THE BACKLIGHT MODULE

摘要

A backlight module and an engagement fitting thereof, and a display device using the backlight module are provided. The backlight module includes: a rear shell including a back plate and a side plate formed with an assembly hole; a middle frame engaged with the side plate and formed with an engagement portion extending toward the assembly hole; and an engagement fitting disposed in a receiving space and adjacent to the side plate. The engagement fitting includes a buckling member and an engagement member penetrating through the assembly hole, the buckling member is for buckling with an optical component set, the engagement member is for engaging with the engagement portion, and thereby achieving tight engagement of the rear shell, the middle frame and the optical component set. The present invention can effectively simplify the structure of the backlight module, improve the structural strength and reduce the production cost.

主权项

1. A backlight module comprising:
a rear shell, comprising a back plate and a side plate, wherein the side plate is disposed at the periphery of the back plate and defines a receiving space for accommodating an optical component set of the backlight module, the side plate is formed with an assembly hole; a middle frame, disposed engaging with the side plate and restricting the optical component set accommodated in the receiving space, wherein the middle frame is formed with an engagement portion extending toward the assembly hole; an engagement fitting, disposed in the receiving space and adjacent to the side plate, wherein engagement fitting comprises a buckling member and an engagement member penetrating through the assembly hole, the buckling member is configured for buckling with the optical component set, the engagement member is configured for engaging with the engagement portion of the middle frame, and thereby achieving tight engagement of the rear shell, the middle frame and the optical component set; wherein a protruding portion of the engagement member penetrating through the assembly hole and engaged with engagement portion is formed with a guiding structure, to thereby allow the protruding portion to withdraw into the assembly hole when the engagement portion presses the guiding structure during assembly and to eject from the assembly hole to engage with the engagement portion when the assembly is completed; the engagement fitting is fixed on the back plate by screwing, riveting, adhering or engagement.
