## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of liquid crystal display packaging, and in particular to a liquid crystal glass panel packaging structure.
2. The Related Arts
In the field of manufacture of liquid crystal display devices, the manufacture of liquid crystal display devices includes a process of assembling, which puts various components, including a liquid crystal glass panel, a main control circuit, and an enclosure, together. These components are each manufactured in advance and packaged for being later assembled to form a complete liquid crystal display device. The liquid crystal glass panel, after being manufactured, is packaged in a liquid crystal glass panel package box and then shipped in box to a corresponding assembling station. Commonly used package boxes include cartoons and plastic cases. Plastic cases have better structures and low prices, but show poor cushioning performance so that cushioning blocks must be additionally provided inside the cases to effect cushioning. Commonly used cushioning blocks are made of foaming substance, such as expandable polyethylene (EPE) and ethylene-vinyl acetate (EVA). These substances are of high prices and are hard to restore after being compressed, making cushioning performance deteriorating and incapable of repeated use, so that the recycling value is low and cost control is hard.
As shown in FIG. 1, a conventional liquid crystal glass panel packaging structure comprises an upper case 100 and a lower case 300. The upper case 100 and the lower case 300 mate each other to form an enclosed package box. The lower case 300 forms therein a receiving chamber 302 and a plurality of cushioning blocks 304 provided along an inside perimeter of the receiving chamber 302. To install, liquid crystal glass panels are positioned in the lower case receiving chamber 302 of the package box and leaning against the cushioning blocks 304 mounted inside the lower case. To ship the liquid crystal glass panels, the cushioning blocks 304 are first disposed along the perimeter inside the lower case 302 of the package box and then the liquid crystal glass panels are positioned into the receiving chamber 302. Finally, the upper case 100 is set to close so as to effectively protect and fix the liquid crystal glass panels, preventing the liquid crystal display modules from being damaged by external forces.
However, the cushioning blocks that are included in the liquid crystal glass panel package are of a high cost and are hard to restore the original shape after being compressed so as to lead to insignificant effect of cushioning. Consequently, it sometimes happens that the liquid crystal glass panels get broken during transportation.
Thus, it is a challenge to the present inventor and those devoted themselves to the art to provide a solution for achieving positioning and cushioning effects for liquid crystal glass panels during transportation by including high performance cushioning devices in a liquid crystal glass panel package and also overcoming the problems of the conventional cushioning devices included in a liquid crystal glass panel package being of high cost and showing insignificant effect of cushioning due to being hard to restore the original shape after being compressed.

Plastic cases are of better structures than commonly used paper cartons and are not easy to break, as well as being humidity resistant and water resistant, so as to provide improved protection. In addition, repeated use of the package box may save packaging cost.
The cushioning bodies 4 are of an H-shape, which comprises a cushioning section 42, a mounting section 44, and a connection section 46 connecting between the cushioning section 42 and the mounting section 44. The cushioning section 42, the mounting section 44, and the connection section 46 are integrally formed and have interior spaces communicating each other and filled with a gas. The gas is usually air. The integrally formed cushioning body 4 has a simple structure and inflation of the whole device can be done by filling air through an air filling opening (not shown) and sealing the air filling opening with a sealing device (not shown) after air filling to thereby achieving an effect of cushioning. To ship the cushioning bodies 4, the gas contained therein is first released to reduce the space occupation rate and thus lowering down transportation cost.
The lower case 22 forms a mounting slot 222 that has an opening 224 to correspond to each of the mounting section 44. The mounting section 44 is received and retained in the mounting slot 222 with the connection section 46 extending through the opening 224, whereby the surface of the cushioning section 42 that opposes the mounting section 44 is positioned against an outside surface of the mounting slot 222. The mounting slot 222 can well retain the H-shaped cushioning body 4 in position, whereby during transportation, since the cushioning effect of the cushioning section 42 is provided by air contained in the cushioning section 42, which undergoes elastic deformation when acted upon by an external force to cushion the external force and quickly restore the original shape when the external force is removed so as to effect better protection of the liquid crystal glass panel 6. Further, arranging the mounting slots 222 inside the package box 2 to fixedly retain the cushioning bodies 4 is of a simple structure and low cost.
Referring to FIGS. 4 and 5, a schematic view is given to show a liquid crystal glass panel packaging structure according to another embodiment of the present invention, which comprises a package box 2 and a plurality of cushioning bodies 4′ arranged inside the package box 2. The package box 2 comprises a lower case 22 and an upper case (not shown) mating the lower case 22. The cushioning bodies 4′ comprise airbag cushioning bodies, which are arranged inside the lower case 22 at locations corresponding to corners of a liquid crystal glass panel 6 in order to protect and cushion the liquid crystal glass panel 6 to prevent the liquid crystal glass panel 6 from being damaged by external forces during transportation and warehousing processes.
