Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

It will be understood that when an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. When an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 11, the present invention provides a film packaging assembly for packaging electronic devices, such as large-sized display screens. It can be understood that in other embodiments, the film packaging assembly can also be applied to package other electronic equipment products, such as tablet computers, notebook computers, hosts, gates, sweeping and mopping all-in-one machines, sweeping and mopping robot base stations, sound boxes, unmanned aerial vehicle mooring boxes and the like, and can also be applied to package living products, such as tables, chairs, storage racks and the like.

At present, for the packaging of some large products (such as electronic devices like large-size display screens), one of the packaging methods is to fix the middle product by two inner liners at the top and the bottom. The specific packaging process is that first one liner is mounted on the bottom of the box, then the product is placed on the liner, and then the second liner is placed on top of the product. In particular, the packing method usually uses foamed materials such as EPS (polystyrene foam) or EPE (pearl wool) or cardboard as an inner liner, the inner liner is opaque, when the top inner liner is installed, a worker cannot see the structure of the inner liner facing the product, and it is difficult to accurately insert and install the liner with the product.

In further detail, the height of the bottom liner is generally lower than the height of the product in order to reduce packaging costs and shipping costs. For thinner products such as display screens, etc., after the product is placed on the bottom liner, the product is prone to tilt in the cabinet due to the center of gravity problem. The gap between the traditional lining and the box body is very small, so that a worker cannot stretch fingers into the lining to straighten the product; and the recess of butt joint with the product installation on the inside lining of top is invisible down, has further increased the installation degree of difficulty of inside lining of top.

Based on this, referring to fig. 1 to 11, the film packaging assembly provided by the present invention includes a box 400 and a liner 200, the liner 200 includes a liner 210 and a film 300, the liner 210 includes a first buffer portion 211 and a second buffer portion 212 connected to each other, a portion of the film 300 is fixed to the first buffer portion 211, a portion of the film 300 is fixed to the second buffer portion 212, the first buffer portion 211 and the second buffer portion 212 surround to form a central through hole, and the film 300 covers at least a portion of the central through hole; the liner 200 is installed on the top of the product 500, and the first buffer portion 211 can be folded and rotated with respect to the second buffer portion 212 and forms an operation space 201 exposing the product 500. It is understood that the positions of the first buffer portion 211 and the second buffer portion 212 can be interchanged.

In the film packaging assembly provided by the invention, when the top liner 200 is installed, a worker can fold and rotate the first buffer part 211 relative to the second buffer part 212, so that an operation space 201 is formed between the box body 400 and the liner 200, and the worker can stably support the product 500 through the operation space 201 to prevent the product 500 from inclining in the box body 400; in addition, the worker can install one of the first buffer portion 211 and the second buffer portion 212 first, and then install the other one, so as to realize visual installation, and the installation of the lining 200 is more time-saving and labor-saving.

It is understood that the film 300 may cover all of the central through hole, or only cover part of the central through hole, and is not limited herein.

As shown in fig. 3-11, in one embodiment, the liner 200 has a first configuration and a second configuration;
