Embodiment Construction
[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0022] Figure 1 includes Picture 1-1 with 1-2 , Shows the structure of the constant force spring 1 used in each preferred embodiment of the present invention. The constant force spring 1 has a fixed end 11 and a supporting end 12. The fixed end 11 is fixed on the side edge of the light guide plate 31, and the supporting end 12 is formed with elastic feet 13, and the feet 13 press against the back plate 32. The fixed end 11, the supporting end 12 and the supporting leg 13 are all f...

The invention discloses a fixing structure of a light guide plate and a backlight module using the fixing structure of the light guide plate. The fixing structure of the light guide plate comprises a first butting-against wall formed on the edge of the side face of the light guide plate, a second butting-against wall formed on a back plate, and a constant force spring arranged between the first butting-against wall and the second butting-against wall. The constant force spring is provided with a fixed end and a supporting end, the fixed end is fixed on the first butting-against wall, an elastic supporting leg is formed at the supporting end, and the supporting leg presses against the second butting-against wall. The light guide plate is fixed with the help of the rebounded force of pre-compressed constant force spring. When the light guide plate expands, the light guide plate can push away the spring to release expansion, and when the light guide plate shrinks, the rebounded force of the spring enables the spring to move together with the light guide plate, and the light guide plate is guaranteed to be fixed.
Description
Technical field [0001] The present invention relates to the field of liquid crystal display device manufacturing, and more specifically, to a light guide plate fixing structure and a backlight module using the fixing structure. Background technique [0002] The backlight module is an indispensable component in the liquid crystal display device. The backlight module usually includes a light guide plate, an LED array, and a back plate. The light guide plate and the back plate are arranged in parallel and fixed together, and the LED array is installed between the light guide plate and the back plate. In the prior art, the method of assembling the light guide plate and the back plate is generally to clamp the light guide plate on the back plate by using a pressure riveting column, or use a rubber pad to fill between the light guide plate and the back plate, and make the guide plate through interference fit. The light board is fixed. However, due to the relatively prominent expansio...
