Referring to fig. 1 to 4, a packing pad assembly according to an embodiment of the present invention includes a first pad 10 and a second pad 20, and each of the first pad 10 and the second pad 20 has a box-shaped structure with an opening at one side.
The second pad 20 is embedded in the inner cavity of the first pad 10, and the second pad 20 is used for at least partially accommodating the to-be-packaged piece.
The inner edge of the opening of the first cushion block 10 is provided with a binding surface 11 matched with the outer peripheral surface of the second cushion block 20, the binding surface 11 is abutted against the outer peripheral surface of the second cushion block 20, and a cavity 13 is arranged between the inner bottom surface of the first cushion block 10 and the outer bottom surface of the second cushion block 20.
In one particular embodiment, as shown in fig. 2 and 3, the first block 10 and the second block 20 each include an outer peripheral surface and a bottom surface, and the surface opposite to the bottom surface is open. Wherein, the peripheral surface is provided with four round chamfers, which is convenient for assembly.
The inner edge of the opening of the first cushion block 10 is provided with a circle of binding surfaces 11, the shape of the binding surfaces 11 is matched with the outer peripheral surface of the second cushion block 20, so that the binding surfaces 11 are tightly attached to the outer peripheral surface of the second cushion block 20 when the second cushion block 20 is embedded in the inner cavity of the first cushion block 10.
As shown in FIG. 4, when the second cushion block 20 is assembled with the first cushion block 10, a cavity 13 is formed between the first cushion block 10 and the second cushion block 20, the outer bottom surface of the second cushion block 20 is not in contact with the inner bottom surface of the first cushion block 10, and the abutting surface 11 is tightly abutted against the outer peripheral surface of the second cushion block 20, so that the cavity 13 is a relatively sealed cavity.
It should be noted that, as shown in fig. 4, when the second cushion block 20 is completely assembled with the first cushion block 10, the outer edge of the second cushion block 20 protrudes outward relative to the outer edge of the first cushion block 10, so as to improve the tightness of the cavity 13 and ensure the cushioning effect of the package cushion block assembly.
According to the packaging cushion block assembly provided by the embodiment of the invention, the binding surface is arranged on the first cushion block, the cavity is arranged between the first cushion block and the second cushion block, the second cushion block is embedded in the first cushion block to form a sealed cavity, when a to-be-packaged piece falls or jolts occurs, the second cushion block extrudes the cavity, the air pressure in the cavity is increased, the second cushion block and the to-be-packaged piece are buffered, the to-be-packaged piece stably falls to the ground, the to-be-packaged piece is protected, and the transportation safety is improved.
In an alternative embodiment, the cavity of the first block 10 tapers from the edge of the abutment surface 11 to the bottom surface of the first block 10.
In this embodiment, the inner wall of the first pad 10 except the abutting surface 11 is in a horn shape which is tapered inward, and the closer the second pad 20 is to the bottom surface of the first pad 10, the larger the pressing force between the inner wall of the first pad 10 and the second pad 20 is. When the second cushion block 20 is assembled with the first cushion block 10, the inner cavity of the first cushion block 10 can form a sealed cavity 13, and the effect of buffering and shock absorption is achieved on the second cushion block 20.
In another alternative embodiment, as shown in fig. 4, the inner cavity of the first pad 10 is gradually enlarged from the edge of the abutting surface 11 to the bottom surface of the first pad 10, and the inner wall of the first pad 10 is further provided with a guide 12.
The guide 12 extends from the edge of the contact surface 11 toward the bottom surface of the first block 10, and the thickness of the guide 12 gradually increases from the edge of the contact surface 11 toward the bottom surface of the first block 10, so that the guide 12 gradually abuts against the outer circumferential surface of the second block 20 along the extending direction.
In this embodiment, the inner wall of the first pad 10 except the abutting surface 11 is in a horn shape gradually expanding inward, so that the volume of the cavity 13 between the first pad 10 and the second pad 20 is increased, and the cushioning performance of the cavity 13 is improved.
As shown in fig. 2, the guide 12 extends in a rib shape from the edge of the contact surface 11 toward the bottom surface of the first block 10, and the thickness of the guide 12 gradually increases from the edge of the contact surface 11 toward the bottom surface of the first block 10, so that the closer the second block 20 is to the bottom surface of the first block 10, the greater the pressing force between the second block 20 and the guide 12 is, the closer the guide 12 is to the outer peripheral surface of the second block 20.
When the second cushion block 20 is assembled with the first cushion block 10, the inner cavity of the first cushion block 10 can form a sealed cavity 13 under the action of the guide member 12, and the second cushion block 20 is cushioned and damped.
Specifically, if the to-be-packaged piece falls from a high position, when the first cushion block 10 touches the ground, the to-be-packaged piece and the second cushion block 20 continue to move towards the bottom surface of the first cushion block 10 under the action of inertia, the second cushion block 20 presses the cavity 13, so that the volume of the cavity 13 is reduced, the air pressure is increased, the to-be-packaged piece and the second cushion block 20 are subjected to air pressure resistance of the cavity 13 to slow down the movement speed, the to-be-packaged piece is buffered and protected, and the received impact is relieved.
And, as the second pad 20 moves towards the bottom surface of the first pad 10, the extrusion force of the guide 12 to the second pad 20 is gradually increased, so that the movement speed of the second pad 20 and the to-be-packaged piece is slowed down, and the buffering effect is enhanced.
Further, the guides 12 are provided in pairs, each pair of guides 12 being oppositely disposed to opposite inner walls of the first head block 10.
In one embodiment, one guide member 12 is disposed on each of the upper surface and the lower surface of the inner cavity of the first cushion block 10, and the thickness of the two guide members 12 gradually increases from the edge of the abutting surface 11 to the bottom surface of the first cushion block 10, that is, the two guide members 12 gradually approach each other in the direction from the edge of the abutting surface 11 to the bottom surface of the first cushion block 10.
In this embodiment, the two guides 12 are disposed opposite to each other, so that when the piece to be packaged is dropped from a high position, the second pad 20 moves toward the bottom surface of the first pad 10 along the axial direction, and the cavity 13 is uniformly pressed by the paired guides 12, thereby ensuring the cushioning effect.
Optionally, the guides 12 are in pairs. For example, the inner cavity of the first pad 10 includes four side walls, each of which has a guide member 12, and the guide members 12 on the opposite side walls are correspondingly positioned. For another example, the inner cavity of the first spacer 10 includes four sidewalls, each of the sidewalls has a plurality of guiding members 12, and the guiding members 12 on the opposite sidewalls are correspondingly positioned.
In a further embodiment, the guide 12 is a resilient member.
Specifically, the guide member 12 may be a soft, resilient material such as rubber, silicone, polystyrene foam, or the like.
In this embodiment, if the piece to be packaged falls from a high position, the second pad 20 presses the guide 12 and the cavity 13, so that the guide 12 is deformed, the volume of the cavity 13 is reduced, the air pressure is increased, and the piece to be packaged and the second pad 20 are subjected to the air pressure resistance of the cavity 13 to slow down the movement.
And when waiting that the package restores to normal steady state of placing, the deformation resilience force of guide 12 promotes second cushion 20 and waits that the package restores to the original position, and the volume reconversion of cavity 13 conveniently treats that the package carries out next buffering shock attenuation.
The guide 12 and the first pad 10 may be an integral structure or a split structure.
In the packaging cushion assembly provided by the embodiment of the invention, the exhaust structure 21 is arranged on the side wall of the second cushion block 20 at a position corresponding to the attaching surface 11.
The air exhaust structure 21 is used for communicating the inner cavities of the first cushion block 10 and the second cushion block 20 when the piece to be packaged falls or collides, so that the air pressure of the cavity 13 is consistent with the external atmospheric pressure.
Specifically, in a stable placement state of the to-be-packaged piece, the vent structure 21 is attached to the attaching surface 11, the first cushion block 10 and the second cushion block 20 are not communicated, and the cavity 13 is in a relatively sealed state.
When the ready-to-package piece falls or collides, the air pressure of the relatively sealed cavity 13 increases, and the ready-to-package piece and the second cushion block 20 are slowed down by the air pressure resistance of the cavity 13.
Along with waiting to pack piece and second cushion 20 and continuing to move to the bottom surface of first cushion 10, exhaust structure 21 and binding face 11 no longer laminate, exhaust structure 21 communicates the inner chamber of first cushion 10 and second cushion 20, and the atmospheric pressure of cavity 13 reduces gradually, and is unanimous with external atmospheric pressure, and the speed of waiting to pack piece and the motion of second cushion 20 at this moment reduces gradually, and until stopping to the bottom surface motion of first cushion 10, it can steadily fall to the ground to wait to pack piece and packing cushion subassembly.
In an alternative embodiment, the venting structure 21 is a through hole in the sidewall of the second pad 20. The shape of the through hole may be circular, rectangular, oval, etc., and the embodiment of the present invention is not particularly limited.
In another alternative embodiment, the top of the sidewall of the second pad 20 is provided with a notch, and the notch forms the air exhaust structure 21.
As shown in FIG. 3, the top of the sidewall of the second pad 20 is provided with a U-shaped groove-like notch, which forms the exhaust structure 21.
In the stable placing state of the to-be-packaged piece, the exhaust structure 21 is located at a position corresponding to the attaching surface 11, the exhaust structure 21 is blocked by the attaching surface 11, the first cushion block 10 is not communicated with the second cushion block 20, and the cavity 13 keeps a relatively sealed state.
When the piece to be packaged falls or collides, the second cushion block 20 moves towards the bottom surface of the first cushion block 10, and the second cushion block 20 is gradually and completely accommodated in the inner cavity of the first cushion block 10. Because the inner cavity of the first cushion block 10 is gradually expanded from the edge of the abutting surface 11 to the bottom surface of the first cushion block 10, the air exhaust structure 21 on the top of the side wall of the second cushion block 20 is separated from the blockage of the abutting surface 11, so that the cavity 13 is communicated with the external atmosphere, and the movement speed of the to-be-packaged piece and the second cushion block 20 is reduced.
Specifically, the exhaust structure 21 is plural.
For example, as shown in fig. 3, each sidewall of the second mat 20 is provided with an exhaust structure 21 to enhance the exhaust effect.
According to the packaging cushion block assembly provided by the embodiment of the invention, the first cushion block 10 and the second cushion block 20 are polystyrene foam pieces, so that the packaging cushion block assembly is light in weight, soft in texture, good in elastoplasticity and durability and beneficial to buffering protection of a to-be-packaged piece.
Further, the mass or density of the first cushion block 10 can be set to be larger than that of the second cushion block 20, so that the risk of damage caused by impact on the first cushion block 10 is reduced, and the safety and reliability of the packaging cushion block assembly are improved.
In the packaging cushion block assembly provided by the embodiment of the invention, the inner bottom surface of the first cushion block 10 is provided with the buffer piece, and the buffer piece is protruded relative to the inner bottom surface of the first cushion block 10.
The buffer piece is used for buffering and protecting the second cushion block 20 when the to-be-packaged piece falls or collides, and the impact on the second cushion block 20 is reduced.
In particular, the buffer is an elastic element or a flexible element.
In an optional embodiment, the inner bottom surface of the first cushion block 10 is provided with a plurality of buffer members which are uniformly distributed, the buffer members are rib-shaped, and the buffer members are rubber members or silica gel members, so that the impact on the second cushion block 20 is reduced.
In another alternative embodiment, the inner bottom surface of the first pad 10 is provided with a plurality of buffers, and the buffers are springs. When the ready-to-package item is dropped or bumped, the second pad 20 moves towards the bottom surface of the first pad 10. When the second pad 20 contacts the buffer, the buffer is compressed, absorbing the impact force, slowing the speed of the second pad 20. When the speed that second cushion 20 moved reduces to 0, the bolster kick-backs, promotes second cushion 20 and outwards moves, makes the volume reconversion of cavity 13, conveniently treats the package and carries out next buffering shock attenuation.
The embodiment of the invention also provides a packaging box, which comprises a box body and the packaging cushion assembly in any one of the embodiments, wherein the packaging cushion assembly is accommodated in the box body.
The packing box is used for packing electronic equipment. For example, in one embodiment, the package is used to package an air conditioner, which may be a wall-mounted air conditioner or a floor-standing air conditioner. When the air conditioner is packaged by the packaging box, two oppositely arranged packaging cushion block assemblies are accommodated in the box body, and the two axial ends of the air conditioner are respectively accommodated in one packaging cushion block assembly to prevent the air conditioner from shifting or colliding along the axial direction.
According to the packing box provided by the embodiment of the invention, the binding surface is arranged on the first cushion block, the cavity is arranged between the first cushion block and the second cushion block, the second cushion block is embedded in the first cushion block to form a sealed cavity, when the to-be-packaged piece falls or jolts, the second cushion block extrudes the cavity, the air pressure in the cavity is increased, the second cushion block and the to-be-packaged piece are buffered, the to-be-packaged piece falls on the ground stably, the to-be-packaged piece is protected, and the transportation safety is improved.
