Description

The present invention relates to a cushion packaging structure, and more particularly to a cushion packaging structure suitable for various articles with different sizes.

[ background of the invention ]

In order to avoid the damage of the appearance or the internal structure of many electronic products caused by the impact or vibration during transportation, the electronic products are wrapped with a buffer packaging structure conforming to the appearance and the size of the electronic products, so that the electronic products can be stably packaged in a transportation carton. However, most of the conventional cushioning packaging structures are developed and manufactured independently for each product, and different products cannot share the same cushioning packaging structure with the same specification. That is, when the size of the new generation product slightly changes or adjusts from the previous generation, in order to stably wrap the product, it is necessary to separately develop and manufacture a buffer packaging structure for the new generation product size, which causes an increase in production cost and easily leads to stocking of too many different types of buffer packaging structures in the warehouse.

It should be noted that, in a variation, the buffering package structure 100 may not have the second side sleeve 2, and may be sleeved between the head and the tail of the electronic product 9 as shown in the buffering package structure 100 in the middle of fig. 3, so as to increase the covering area of the electronic product 9.

Referring to fig. 4 and 5, the connecting blocks 3 are connected between the first extending arms 13 of the first side covers 1, and each connecting block 3 is connected between the corresponding first extending arms 13 in the left-right direction D1. Each connecting block 3 comprises a central portion 31, and two mobile units 32. The central portion 31 has two surfaces 311 disposed at opposite sides, and defines two engaging grooves 312 recessed from the left and right sides. More specifically, the central portion 31 has a waist section 313 and two connecting sections 314 extending from the upper and lower ends of the waist section 313 toward a direction away from the waist section 313, respectively, and having gradually expanding outer diameters. The waist section 313 has four first wall surfaces 313a, and the first wall surfaces 313a are distributed on the left and right sides of the waist section 313 in pairs.

The first coupling end 321a is rotatably connected to the coupling segment 314, and the second coupling end 321b is rotatably connected to the connecting end 131 of the first extension arm 13. The outer side face 321c of each movable wall 321 is parallel to the engaging end face 321 d.

Referring to fig. 1, 2, 4 and 5, the movable units 32 on the same side of the connection blocks 3 can move between a retracted position shown in fig. 1 and 4 and an extended position shown in fig. 2 and 5 relative to the central portion 31, so that the capacity of the first nesting space 11 in the extended position is greater than that in the retracted position. In detail, when the movable units 32 are at the retracted position, the movable units 32 are respectively accommodated in the engaging grooves 312, and the movable walls 321 of each movable unit 32 are respectively rotated toward the groove 312a and accommodated in the groove 312a with the respective first connecting end 321a as a rotation center, so that the engaging end surfaces 321d of the movable walls 321 are respectively engaged with the first retracting wall surfaces 313a on the same side of the central portion 31, and the first engaging surfaces 321e of the movable walls 321 are respectively engaged with the second retracting wall surfaces 314a on the same side of the central portion 31; in addition, the second side engagement surfaces 321f of the movable walls 321 define a triangular folding space, the connection end portion 131 of the first extension arm 13 is drawn by the second connection end portions 321b of the movable walls 321 to extend into the folding space, so that the inclined engagement surfaces 131a of the connection end portion 131 are respectively engaged with the second side engagement surfaces 321f of the movable walls 321, and the corresponding first extension arms 13 are relatively close to each other in the left-right direction D1. In addition, the inclined junctions 131a of each connecting end 131 are respectively parallel to the first side junction surfaces 321e of the movable walls 321 of the corresponding movable unit 32.

Referring to fig. 2, 5 and 6, when the electronic product 9 to be packaged has a larger size, at least one of the two first side sleeves 1 can be selectively pulled to move away from the central portion 31, so as to extend the length of the first engaging space 11 in the left-right direction D1. During pulling, the connecting end 131 of the first extension arm 13 pulls the movable walls 321 to rotate away from the slots 312a with the first connecting end 321a as a rotation center, the second connecting end 321b also rotates toward the end of the connecting end as a rotation center until the connecting end 321D are straightly connected to each other, the first side connecting surfaces 321e are straightly connected to each other, the outer side surfaces 321c are horizontally connected to the surfaces 311, and the movable units 32 reach the extended position to make the corresponding first extension arms 13 in the left-right direction D1 relatively away from each other. Therefore, by selectively pulling at least one of the two first side sleeves 1, the cushion packaging structure can be in three states of double-side unfolding, single-side unfolding or non-unfolding, and further, the electronic products 9 with three different sizes can be selectively packaged. In addition, in an alternative embodiment, the cushion packaging structure 100 may further include four connecting blocks 3 disposed between the corresponding first extension arms 13 and the corresponding second extension arms 23, so that the second side sleeve 2 can be expanded outwards relative to the first side sleeve 1 by the movable units 32 of the connecting blocks 3, thereby increasing the capacity of the second sleeving space 21, and further being capable of selectively packaging electronic products 9 with more sizes.

This paragraph describes the proportional relationship between the connector block 3 and the first extension arm 13. Defining the length of any outer side 321c of any movable wall 321 of the connecting block 3 as Q, the length of each inclined joint 131a of the connecting end 131 is 2Q, the length of each first converging wall 313a is 0.5Q, and the length of each second converging wall 314a is between Q and 4/3Q. In addition, when the movable unit 32 is located at the retracted position, the distance between the upper arm surface 132 and the upper surface 311a in the left-right direction D1 is Y, and when the movable unit 32 is located at the extended position, the distance between the upper arm surface 132 and the upper surface 311a in the left-right direction D1 is Y +1/2Y + Q. In addition, when the movable unit 32 is located at the retracted position, an included angle between each outer side surface 321c and the corresponding inclined joint surface 131a is M, an included angle between the joint end surfaces 321d of the movable walls 321 is N, and M is 90 degrees in the present embodiment, where N is equal to M, but M may be between 90 degrees and 150 degrees in a variation implementation.

In summary, the cushion packaging structure 100 of the present invention utilizes the movable unit 32 connected between the first side sleeves 1 and the central portion 31 of the connecting block 3 to enable the first side sleeves 1 to be relatively far away from or relatively close to each other in the left-right direction D1, so that the first engaging space 11 defined by the cushion packaging structure 100 can be changed between at least three different sizes of capacity, and further can be suitable for sleeving at least three different sizes of electronic products 9, thereby achieving the objective of the present invention.
