As shown in FIG. 1 to FIG. 4 , the packaging cushion block assembly provided in the embodiment of the present invention includes a first cushion block 10 and a second cushion block 20 , and the first cushion block 10 and the second cushion block 20 are both box-shaped structures with one side open.

The second cushion block 20 is embedded in the inner cavity of the first cushion block 10 , and the second cushion block 20 is used to at least partially accommodate the items to be packaged.

The inner edge of the opening of the first cushion block 10 is provided with a fitting surface 11 adapted to the outer peripheral surface of the second cushion block 20 . The fitting surface 11 abuts against the outer peripheral surface of the second cushion block 20 . A cavity 13 is defined between the inner bottom surface of the first cushion block 10 and the outer bottom surface of the second cushion block 20 .

In a specific embodiment, as shown in Figures 2 and 3, the first cushion block 10 and the second cushion block 20 both include an outer peripheral surface and a bottom surface, and one surface opposite to the bottom surface is open. The outer peripheral surface is provided with four rounded chamfers for easy assembly.

The inner edge of the opening of the first cushion block 10 is provided with a circle of fitting surface 11, the shape of which is adapted to the outer peripheral surface of the second cushion block 20, so that when the second cushion block 20 is embedded in the inner cavity of the first cushion block 10, the fitting surface 11 and the outer peripheral surface of the second cushion block 20 are tightly fitted.

As shown in Figure 4, when the second cushion block 20 and the first cushion block 10 are assembled, there is a cavity 13 between the first cushion block 10 and the second cushion block 20, and the outer bottom surface of the second cushion block 20 does not contact the inner bottom surface of the first cushion block 10. Since the fitting surface 11 and the outer peripheral surface of the second cushion block 20 are tightly fitted, 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 assembled with the first cushion block 10 , the outer edge of the second cushion block 20 is convex relative to the outer edge of the first cushion block 10 to improve the airtightness of the cavity 13 and ensure the cushioning effect of the packaging cushion block assembly.

The packaging cushion block assembly provided in the embodiment of the present invention, by arranging a fitting surface on the first cushion block and arranging a cavity between the first cushion block and the second cushion block, so that the second cushion block is embedded in the first cushion block to form a sealed cavity in the first cushion block; when the item to be packaged falls or is bumped, the second cushion block squeezes the cavity, and the air pressure in the cavity increases, which has a buffering effect on the second cushion block and the item to be packaged, so that the item to be packaged lands safely, thereby protecting the item to be packaged and improving transportation safety.

In an optional embodiment, the inner cavity of the first cushion block 10 is tapered from the edge of the fitting surface 11 to the bottom surface of the first cushion block 10 .

In this embodiment, the inner wall of the first cushion block 10 except the fitting surface 11 is in a trumpet shape that gradually contracts inwards, and the closer the second cushion block 20 is to the bottom surface of the first cushion block 10, the greater the squeezing force between the inner wall of the first cushion block 10 and the second cushion block 20. When the second cushion block 20 and the first cushion block 10 are assembled, the inner cavity of the first cushion block 10 can form a sealed cavity 13, which plays a role in buffering and shock absorbing the second cushion block 20.

In another optional embodiment, as shown in FIG. 4 , the inner cavity of the first cushion block 10 is gradually expanded from the edge of the fitting surface 11 to the bottom surface of the first cushion block 10 , and a guide member 12 is further provided on the inner wall of the first cushion block 10 .

The guide member 12 extends from the edge of the fitting surface 11 to the bottom surface of the first cushion block 10, and the thickness of the guide member 12 gradually increases from the edge of the fitting surface 11 to the bottom surface of the first cushion block 10, so that the guide member 12 gradually fits closely to the outer peripheral surface of the second cushion block 20 along the extension direction.

In this embodiment, the inner wall of the first cushion block 10 except the fitting surface 11 is in a trumpet shape that gradually expands inward, so that the volume of the cavity 13 between the first cushion block 10 and the second cushion block 20 is increased, thereby improving the cushioning performance of the cavity 13 .

2 , the guide member 12 extends from the edge of the fitting surface 11 to the bottom surface of the first pad 10 in the shape of a convex rib, and the thickness of the guide member 12 gradually increases from the edge of the fitting surface 11 to the bottom surface of the first pad 10, so that the closer the second pad 20 is to the bottom surface of the first pad 10, the greater the extrusion pressure between the second pad 20 and the guide member 12, and the closer the guide member 12 is to the outer peripheral surface of the second pad 20.

When the second cushion block 20 is assembled with the first cushion block 10 , under the action of the guide member 12 , the inner cavity of the first cushion block 10 can form a sealed cavity 13 , which plays a role in buffering and shock absorbing the second cushion block 20 .

Specifically, if the item to be packaged falls from a height and the first cushion block 10 touches the ground, the item to be packaged and the second cushion block 20 continue to move toward the bottom surface of the first cushion block 10 under the action of inertia, and the second cushion block 20 squeezes the cavity 13, thereby reducing the volume of the cavity 13 and increasing the air pressure. The air pressure resistance of the cavity 13 slows down the movement of the item to be packaged and the second cushion block 20, and the item to be packaged is cushioned and protected, thereby reducing the impact.

Furthermore, as the second cushion block 20 moves toward the bottom surface of the first cushion block 10, the squeezing force of the guide member 12 on the second cushion block 20 gradually increases, thereby slowing down the movement speed of the second cushion block 20 and the object to be packaged and enhancing the buffering effect.

Furthermore, the guide members 12 are arranged in pairs, and each pair of guide members 12 is arranged on opposite inner walls of the first cushion block 10 .

In one embodiment, a guide member 12 is provided on 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 fitting surface 11 to the bottom surface of the first cushion block 10, that is, from the edge of the fitting surface 11 to the bottom surface of the first cushion block 10, the two guide members 12 gradually approach each other.

In this embodiment, the two guide members 12 are arranged opposite to each other, so that when the packaged item falls from a height, the second cushion block 20 moves along the axial direction toward the bottom surface of the first cushion block 10, and the cavity 13 is evenly squeezed under the action of the paired guide members 12 to ensure the buffering and shock absorbing effect.

Optionally, there are multiple pairs of guide members 12. For example, the inner cavity of the first cushion block 10 includes four side walls, each of which is provided with a guide member 12, and the guide members 12 on the opposite side walls are located in corresponding positions. For another example, the inner cavity of the first cushion block 10 includes four side walls, each of which is provided with multiple guide members 12, and the guide members 12 on the opposite side walls are located in corresponding positions.

In a further embodiment, the guide member 12 is an elastic member.

Specifically, the guide member 12 can be made of a rubber member, a silicone member, a polystyrene foam member or other soft material with deformation resilience.

In this embodiment, if the packaged item falls from a height, the second cushion block 20 squeezes the guide member 12 and the cavity 13, causing the guide member 12 to deform, and the volume of the cavity 13 to decrease, thereby increasing the air pressure. The packaged item and the second cushion block 20 are slowed down by the air pressure resistance of the cavity 13.

When the packaged item returns to its normal stable placement state, the deformation resilience of the guide member 12 pushes the second cushion block 20 and the packaged item back to their original positions, and the volume of the cavity 13 returns to its original state, making it convenient for the next buffering and shock absorption of the packaged item.

The guide member 12 and the first cushion block 10 may be an integrated structure or a split structure.

In the packaging cushion block assembly provided in the embodiment of the present invention, an exhaust structure 21 is provided on the side wall of the second cushion block 20 at a position corresponding to the fitting surface 11 .

The exhaust structure 21 is used to connect the inner cavities of the first cushion block 10 and the second cushion block 20 when the package falls or collides, so that the air pressure of the cavity 13 is consistent with the external atmospheric pressure.

Specifically, when the packaged item is placed stably, the exhaust structure 21 is in contact with the contact surface 11 , the first cushion block 10 and the second cushion block 20 are not connected, and the cavity 13 is in a relatively sealed state.

When the packaged object falls or collides, the air pressure in the relatively sealed cavity 13 increases, and the movement of the packaged object and the second cushion block 20 is slowed down by the air pressure resistance of the cavity 13 .

As the packaged items and the second cushion block 20 continue to move toward the bottom surface of the first cushion block 10, the exhaust structure 21 is no longer in contact with the bonding surface 11, and the exhaust structure 21 connects the inner cavities of the first cushion block 10 and the second cushion block 20. The air pressure in the cavity 13 gradually decreases until it is consistent with the external atmospheric pressure. At this time, the movement speed of the packaged items and the second cushion block 20 gradually decreases until they stop moving toward the bottom surface of the first cushion block 10, and the packaged items and the packaging cushion block assembly are able to land safely.

In an optional embodiment, the exhaust structure 21 is a through hole on the side wall of the second cushion block 20. The shape of the through hole can be circular, rectangular, elliptical, etc., which is not specifically limited in the embodiment of the present invention.

In another optional embodiment, a notch is provided at the top of the side wall of the second cushion block 20 , and the notch forms an exhaust structure 21 .

As shown in FIG. 3 , a U-shaped groove-shaped notch is provided on the top of the side wall of the second cushion block 20 , and the notch forms an exhaust structure 21 .

When the package is stably placed, the exhaust structure 21 is located at a position corresponding to the fitting surface 11, the exhaust structure 21 is blocked by the fitting surface 11, the first cushion block 10 is not connected to the second cushion block 20, and the cavity 13 remains relatively sealed.

When the packaged object falls or collides, the second cushion block 20 moves toward 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. Since the inner cavity of the first cushion block 10 gradually expands from the edge of the bonding surface 11 to the bottom surface of the first cushion block 10, the exhaust structure 21 on the top of the side wall of the second cushion block 20 is freed from the blockage of the bonding surface 11, so that the cavity 13 is connected to the outside atmosphere, slowing down the movement speed of the packaged object and the second cushion block 20.

Specifically, there are multiple exhaust structures 21.

For example, as shown in FIG. 3 , exhaust structures 21 are provided on each side wall of the second cushion block 20 to enhance the exhaust effect.

In the packaging cushion block assembly provided in the embodiment of the present invention, the first cushion block 10 and the second cushion block 20 are polystyrene foam parts, which are light in weight, soft in texture, have good elasticity and durability, and are beneficial for cushioning and protecting the packaged items.

Furthermore, the mass or density of the first cushion block 10 may be set to be greater than the mass or density of the second cushion block 20, thereby reducing the risk of damage to the first cushion block 10 caused by impact and improving the safety and reliability of the packaging cushion block assembly.

In the packaging cushion block assembly provided by the embodiment of the present invention, a buffer is provided on the inner bottom surface of the first cushion block 10 , and the buffer is raised relative to the inner bottom surface of the first cushion block 10 .

The buffer is used to provide buffer protection for the second cushion block 20 when the package falls or collides, thereby reducing the impact on the second cushion block 20 .

Specifically, the buffer member is an elastic member or a flexible member.

In an optional embodiment, the inner bottom surface of the first cushion block 10 is provided with a plurality of evenly distributed buffers, which are in the shape of convex ribs and are rubber or silicone members, so as to reduce the impact on the second cushion block 20 .

In another optional embodiment, the inner bottom surface of the first cushion block 10 is provided with a plurality of buffers, and the buffers are springs. When the package to be packaged falls or collides, the second cushion block 20 moves toward the bottom surface of the first cushion block 10. When the second cushion block 20 contacts the buffer, the buffer is compressed, absorbing the impact force, and slowing down the movement speed of the second cushion block 20. When the movement speed of the second cushion block 20 decreases to 0, the buffer rebounds, pushing the second cushion block 20 to move outward, so that the volume of the cavity 13 is restored to its original state, which is convenient for the next buffering and shock absorption of the package to be packaged.

An embodiment of the present invention further provides a packaging box, comprising a box body and a packaging cushion block assembly as described in any of the above embodiments, wherein the packaging cushion block assembly is accommodated in the box body.

The packaging box is used to package electronic equipment. For example, in one embodiment, the packaging box is used to package an air conditioner, which may be a wall-mounted air conditioner or a vertical air conditioner. When the packaging box is used to package the air conditioner, two packaging cushion block assemblies arranged opposite to each other are placed in the box body, and the axial ends of the air conditioner are each placed in a packaging cushion block assembly to prevent the air conditioner from moving or colliding along the axial direction.

The packaging box provided by the embodiment of the present invention has a fitting surface arranged on the first cushion block and a cavity arranged between the first cushion block and the second cushion block, so that the second cushion block is embedded in the first cushion block to form a sealed cavity inside the first cushion block. When the item to be packaged falls or is bumped, the second cushion block squeezes the cavity, and the air pressure in the cavity increases, which has a buffering effect on the second cushion block and the item to be packaged, so that the item to be packaged lands safely, thereby protecting the item to be packaged and improving transportation safety.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
