A cushioning device for a display screen in the prior art generally includes a cushioning block body and a flat silicone attached to the cushioning block body. Specifically, when the display screen needs to protect, the cushioning block body is arranged on one side of the display screen, and the flat silicone contacts with an end plane of the display screen. Thus, when the display screen is shocked or impacted during transportation, the display screen can be cushioned by the flat silicone. However, a cushioning area on the display screen formed by the flat silicone is a contact area between the flat silicone and the display screen. An area of the flat silicone cannot be designed to be larger due to a limitation of the size of the cushioning block body. Therefore, a stress concentration is formed between the display screen and the flat silicone during transport, and thereby made a poor cushioning effect of the display screen, which is not conducive to the protection of the display screen.

In order to describe the technical solutions described in the present application, the specific embodiments provided in the present application are described in detail below with reference to the accompanying drawings.

As shown inFIGS. 1 to 6, an embodiment of the application provides a cushioning device, which includes a cushioning block body11and a cushioning pad20. One side of the cushioning block body11defines a holding groove15for holding a display panel (not shown in the accompanying drawings). An inside surface of the holding groove15may be substantially an arcuate surface151. A shape of the cushioning pad20corresponds to a shape of the arcuate surface151. The cushioning pad20includes an extrados21and an intrados22opposite to the extrados21. The extrados21is fixedly connected to the arcuate surface151.

In one embodiment, an arc center of the arcuate surface151(that is a centre of a circle what the arcuate surface151belongs) is located in a position orientated by an opening of the holding groove15. Similarly, an arc center of the intrados22of the cushioning pad10is also located in a position orientated by an opening of the holding groove15. In this way, when the display panel is embedded in the cushioning device10, an edge of the display panel is embedded into the holding groove15, and contacted with the intrados22of the cushioning pad20. Because the edge of the display panel and the intrados22are connected with each other via a curved surface, thus it can increase a contact area between the edge of the display panel and the intrados22, and thereby greatly reduce a pressure per unit area of the contact surface between the display panel and the intrados22. Therefore, it can avoid cracks formed on the contact area between the display screen and the intrados22due to an excessive pressure per unit area.

According to the cushioning device of the embodiment of the present application, one side of the cushioning block body11defines the holding groove15, to allow the edge of the display panel to be embedded in the holding groove15, and to allow the display panel to be firmly embedded and pressed against the cushioning device10. Because the inside surface of the holding groove15is an arcuate surface, so that the edge of the display panel can be embedded in the holding groove15, and thereby the display panel may not generate upward and downward displacements due to jolts and impacts during transportation. Thus, it can avoid touch and break due to the upward and downward displacements of the display panel. In addition, the shape of the cushioning pad20corresponds to the inside surface of the holding groove15; the extrados of the cushioning pad20is attached and fixed to the inside surface of the holding groove15; and the intrados22of the cushioning pad20is embedded in the edge of the display panel. In this way, a contact area between the edge of the display panel and the cushioning pad20can be significantly increased, and eliminate a hidden danger that cracks are formed on a contact area between the display panel and the cushioning pad20due to stress concentration, and thereby significantly improve a cushioning effect of the cushioning device10on the display panel.

In one embodiment, two opposite ends of an upper surface of the cushioning block body11and two opposite ends of a lower end surface of the cushioning block body11are defines cushioning fillets. The cushioning fillet is configured for the cushioning device10to be easily embedded into the display screen storage device40. Meanwhile, the cushioning device10and the display screen storage device40are connected with each other via a curved surface, thus it can increase the contact area between the cushioning device10and the display screen storage device40, and thereby greatly reduce a pressure per unit area of the contact surface and evenly distribute the pressure on the contact surface. Therefore, it can effectively avoid an excessive pressure of the contact area formed between the cushioning device10and the display panel, and cracks, which cause a failure of the display screen storage device40or the cushioning device10, formed on the contact area between the cushioning device10and the display screen storage device40due to jolts and impacts during transportation of the display panel.

In one embodiment, as shown inFIGS. 1, 3, and 5, a lower end of the arcuate surface151extends upward to form a lower limit protrusion12, and an upper end of the arcuate surface151extends downward to form an upper limit protrusion13. The lower limit protrusion12corresponds to the upper limit protrusion13, and the upper limit protrusion13is located above the lower limit protrusion12. Furthermore, a lower limit groove121is formed between one side of the lower limit protrusion12facing to the arcuate surface151and the lower end of the arcuate surface151, and an upper limit groove131is formed between one side of the upper limit protrusion13facing to the arcuate surface151and the lower end of the arcuate surface151. Furthermore, the upper end of the cushioning pad20is embedded in the upper limit groove131, and the lower end of the cushioning pad20is embedded in the lower limit groove121.

In this way, because of the existences of the upper limit groove131and the lower limit groove121, the upward and downward displacements of the cushioning pad20in the holding groove15are further limited, thus the cushioning pad20can be more firmly embedded in the holding groove15. In this way, a separation between the cushioning block body11and the cushioning pad20of the display screen storage device40can be avoided due to jolts and impacts during transportation of the display screen, so the cushioning pad20is loosened from the display panel out of the holding groove15and displaced up and down, and it can ensure that the display panels will not break, which touch each other due to upward and downward displacements during transportation.

In one embodiment, as shown inFIGS. 1, 3, and 5, the arcuate surface151is adhered to the extrados21of the cushioning pad20via an adhesive layer, so that the cushioning pad20is fixedly connected with the cushioning block body11. The adhesive layer may be double-sided adhesive or viscose glue. A type of the adhesive layer is not particularly limited by the embodiment.

The arcuate surface151is adhered to extrados21of the cushioning pad20by double-sided adhesive to facilitate an assembly of the cushioning device10more convenient and easier. In an assembling process of the cushioning device10, firstly, an adhesive surface of one side of the double-sided adhesive may be adhered to the arcuate surface151or the extrados21of the cushioning pad20. Then, when the cushioning device10needs to be adhered and fixed with the holding groove15, a sticker on the other side of the double-sided adhesive can be peeled off, and the adhesive surface on the other side of the double-sided adhesive is adhered and fixed to the extrados21of the cushioning pad20or the arcuate surface151of the holding groove15, so as to realize that the extrados21of the cushioning pad20is adhered and fixed to the arcuate surface151, and the cushioning pad20is adhered and fixed to the cushioning block body11. In this way, the arcuate surface151and the extrados21of the cushioning pad20are adhered and fixed by the double-sided adhesive, thus the assembly process of the cushioning device10can be greatly simplified and standardized.

In one embodiment, firstly, the double-sided adhesive may be attached to the extrados21of the cushioning pad20or the arcuate surface151. Because the adhesive surface on other side of the double-sided adhesive has the sticker, which protects the double-sided adhesive from an infection of dust impurities, and keeps long-term enough cohesion. Secondly, the extrados21of the cushioning pad20or the arcuate surface151of the holding groove15can be evenly adhered and fixed on the adhesive surface of the other side of the double-sided adhesive, so the extrados21of the cushioning pad20can be adhered and fixed on the arcuate surface151, and the assembly of the buffer device10can be standardized.

In one embodiment, the arcuate surface151and the extrados21of the cushioning pad20are adhered and fixed by the viscose glue, so the arcuate surface151is adhered to the extrados21of the cushioning pad20more firmer. Meanwhile, the viscose glue can be evenly coated on the arcuate surface151or the extrados21of the cushioning pad20, and then the arcuate surface151and the outer arcuate surface21of the cushion pad20are tightly attached together. In this way, a cementing layer is evenly distributed between the arcuate surface151and the outer arcuate surface21of the cushion pad20, so the arcuate surface151and the outer arcuate surface21of the cushion pad20may be tightly attached together; and the cushioning pad20and the cushioning block body11may be firmly connected together, which will not be separated due to the jolts and impacts during the transportation of the display screen.

In this embodiment, the arcuate surface151and the outer arcuate surface21of the cushion pad20are adhered and fixed by the viscose glue, so as to ensure a stronger integrality of the cushioning device10, and thus the cushioning device10cannot easily break when subjected to the impacts. A material of the cushioning pad20may be preferably silicone or rubber, which can also be any other soft materials. When the silicone is selected as the material of the cushioning pad20, the cushioning pad20may have good elasticity. Thus, when the edge of the display panel impacts the cushioning pad20, the cushioning pad20made of the silicone can enable a large elastic deformation, and the impacts of the display panel can be minimized to maximize a protection of the display panel and the display screen storage device40. When the rubber is selected as the material of the cushioning pad20, the cushioning pad20may have a good durability. The cushioning device10assembled the cushioning pad20can be served for a long time in the display screen storage device40, and reduce a rate of repairing and replacing the cushioning device10, and an operating cost of the display screen storage device40.

In this embodiment, as shown inFIGS. 1, 3 and 5, the upper and lower end of the cushioning block body11, two side surfaces of the cushioning block body11, and the arcuate surface151of the holding groove15cooperatively form a vertical cushioning area. The vertical cushioning area defines a plurality of cushioning holes16, and axial directions of the plurality of cushioning holes16are parallel to the arcuate surface151. Because the vertical cushioning area defines the plurality of cushioning holes16, when the cushioning holes16are subjected to a transient impact force, the cushioning holes16may deform instantaneously. When the cushioning holes16deform instantaneously, the impacts acting on the cushioning device10can be significantly absorbed by the cushioning holes16. Furthermore, the cushioning device10can be prevented from cracks, break causing failure, or separation between the cushioning pad20and the cushioning block body11, which causes failure of the buffer device10, due to the instantaneous impacts thereon.

In one embodiment, the cushioning holes16are evenly distributed on the vertical cushioning area. For example, spacing between the adjacent cushioning holes16is the same, so an impact load bear by each cushioning holes16may substantially keep consistent, and it can avoid cracks, because the cushioning holes16are densely distributed in a local area, which cause wall thickness in an area around the cushioning holes16too thin, and insufficient strength of an inner wall of the cushioning holes16. In such way, it can also avoid an occurrence of break and failure phenomenon at the inner wall of the cushioning holes16of the cushioning device10.

In one embodiment, as shown inFIGS. 1, 3, and 5, a shape of the cushioning holes16may be any shape. For example, the shape of the cushioning holes16is substantially circular, oval, or the like. When the shape of the cushioning holes16is designed as circular, the cushioning holes16can evenly bear the impact force in all directions. When the shape of the cushioning holes16is designed as oval, the cushioning holes16can specifically buffer the impact force in a certain direction. For example, in an actual situation, when a predictable impact force from up and down direction is large, the cushioning holes16can be designed as the oval, and a long axis direction of the oval can be substantially parallel to an acting direction of the impact force. Of course, the shape of the oval hole can also be designed as rectangle or diamond according to the actual situation. In this embodiment, the shape of the buffer hole16is not particularly limited.

In one embodiment, the cushioning holes16are evenly distributed on the vertical cushioning area, so that the material of the cushioning device10can be saved, a manufacturing cost of the cushioning device10can be reduced, and a weight of the cushioning device10can also be reduced. At the same time, the cushioning holes16are evenly distributed, to make a thickness of an area between axial directions of the cushioning holes16be relatively even; facilitate molding of a mold; avoid occurrence of process defects due to the uneven thickness; and increase a yield of the cushioning device10.

In one embodiment, elastomeric material can be filled in the cushioning holes16, such as silicone or rubber. In this way, when the cushioning holes16bear a larger impact force and deform, the elastomeric material within the cushioning holes16can disperse the pressure and play an integral supporting role to the cushioning holes16, so a cracking risk of the cushioning holes16can be avoided, and thereby a risk of failure caused the cracks due to a transient high impact of the cushioning device10can be reduced.

In one embodiment, as shown inFIGS. 1, 4 and 5, the intrados22of the cushioning pad20further defines a plurality of arcuate recesses, which are arranged side by side and parallel to the axial directions of the cushioning holes16, and configured for holding the display panel. In this way, the edge of the display panel can be firmly embedded in the holding groove15, and the edge of the display panel is contacted with each of the arcuate recesses, so the arcuate recesses can sandwich both the upper and lower end of the edge of the display panel; increase a contact area between a sandwiching gap and the display panel; and thereby firmly fix the display panel within the arcuate recesses.

In addition, the edge of the display panels can be spaced from each other and embedded in the arcuate recesses of the cushioning pad20due to existences of the arcuate recesses of the cushioning pad20, thus the display panels can be alternately embedded in the display screen storage device40from top to bottom, so as to allow the display panels to have a sufficient vertical cushioning gap in between. When the display panel is shocked or impacted during transportation, each of the display panels may have the vertical cushioning gap, which can effectively avoid an impact that the display panels touch each other due to the upward and downward displacements causing the display panel to break.

Of course, a shape of the arcuate recesses on the intrados22of the cushioning pad20may be an arc shape, a wave shape, a rectangular shape, a convex shape, or a stepped shape according to an actual situation. When the shape of a protrusion on the intrados22of the cushioning pad20is the arc shape or the wave shape, the cushioning pad20is contacted to a curved surface of the edge of the display panel by an arcuate protrusion to increase the contact area between the edge of the display panel and the cushioning pad20, and thereby reduce a pressure that the cushioning pad20bear on per unit area. Thus, the cracks formed on the cushioning pad20can be avoided, which are caused by the stress concentration due to the impact of the display panel. When the shape of the protrusion on the intrados22of the cushioning pad20is the rectangular shape, the convex shape or the stepped shape, a manufacturing process may be relatively simple because of a simple structure of the rectangular shape, the convex shape and the stepped shape, which are simply formed by a plane. Thereby, the manufacturing process of the cushioning pad20can become easily, a cost of a mold can be low, and a manufacturing cost of the cushioning card20can be effectively reduced.

In one embodiment, as shown inFIGS. 1, 4, and 5, a width of two adjacent arcuate recesses may be in a range of 1.2 mm to 2 mm. That is the width of the convex groove may be in a range of 1.2 mm to 2 mm. The gap of 1.2 mm to 2 mm can be met for holding the various types of display panels with the width of 1.2 mm to 2 mm. In this way, the width of the convex groove is defined as 1.2 mm to 2 mm, which can significantly enhance the variety of the display panels embedded in the display screen storage device40.

In one embodiment, as shown inFIGS. 1, 4 and 5, the extrados21of the cushioning pad20is further provided with a plurality of arcuate protrusions, which are arranged side by side and parallel to the axial directions of the cushioning holes16. A flexible gap is formed between two adjacent arcuate protrusions to facilitate deformation of the arcuate protrusions. In this way, the cushioning pad20subjected to an extrusion can deform. Because the extrados21is provided with the plurality of arcuate protrusions arranged on side by side and parallel to the cushioning hole16, when the extrados21is bent and deformed, the arcuate protrusions are close to each other, and squeeze the flexible gap so as to avoid each of the arcuate protrusions squeeze each other. Thus a gap, which declines a fastness of a bonding in between, is formed between the extrados21of the cushioning pad20and the arcuate surface151of the holding groove15. Furthermore, it can avoid that the extrados21of the cushioning pad20and the arcuate surface151of the holding groove15are separated due to a declined degree of adhesion in between, and avoid the failure causing the break of an integrality of the cushioning device10. Furthermore, it ensures that the edge of the display panel can be firmly fixed in the holding groove15without being slipped out of the holding groove15because the cushioning pad20is deformed and separated from the holding groove15.

One embodiment of the present application further provides a display screen storage device40, as shown inFIG. 5, which includes a receiving box33. The receiving box33has a receiving cavity30. Both a length and a width of the receiving cavity30can be designed according to the length and the width of the display panel, a depth of the receiving cavity30can be designed according to the number of the display panel accommodated therein. In this way, a size of the receiving cavity30can be matched with an overall size of the display panel received therein, so that a space of the received cavity30can be effectively utilized. At the same time, the receiving cavity30further includes four corners32. The cushioning device10is arranged at each corner32, and the holding groove15of the cushioning device10faces towards the receiving cavity30.

In one embodiment, in the receiving cavity30, the edge of the display panel is arranged on the corners32of the receiving cavity30of the cushioning device10, so that a cushion is formed between the display panel and the receiving cavity30of the display screen storage device40to prevent the display panel from impacting with a side wall of the receiving cavity30, and thereby prevent cracks formed on the display panel or an inner wall of the receiving cavity30, or a break of the display panel. Thus, it can ensure that, in a process of long distance transport, when the display screen storage device40is shocked and impacted, the display panels receiving in thereof can keep intact, and the display screen storage device40itself can also keep intact.

At the same time, the cushioning device10defines a cushioning fillet14, and the cushioning fillet14in the receiving cavity30may contact with an inside wall and a bottom of the receiving cavity30to increase a contact area between the cushioning device10and the inside wall and the bottom of the receiving cavity30, and reduce a pressure under per unit area of a contact surface formed between the cushioning device10and the inside wall and the bottom of the receiving cavity30. So it can eliminate a stress concentration formed on the contact surface between the cushioning device10and the inside wall and the bottom of the receiving cavity30, and significantly reduce an odds ratio of the cracks generated on the contact surface between the cushioning device10and the inside wall and the bottom of the receiving cavity30due to impacts and jolts. In this way, the display screen storage device40can be avoided that the inside wall crack because the cushioning device10impacts with the inside wall of the receiving cavity30during in the transportation of the display screen due to an impact force, causing cracks of the display screen storage device40, and thereby effectively ensure a transport quality of the display screen, and extend a life of the display screen storage device40.

In one embodiment, as shown inFIG. 5, the holding groove151of the cushioning device10faces towards the receiving cavity30. In this way, the edge of the display panel can be embedded in the holding groove15to make the display panel to be firmly received in the receiving cavity30. At the same time, the corner32of the receiving cavity30arranges at least two cushioning devices10, and orientations of the holding grooves15of the at least two cushioning devices10on the corner32are perpendicular to each other. An outside wall of the cushioning device10without defining the holding groove15is attached and fixed to the inside wall of the receiving cavity30, and the bottom of the receiving cavity30also defines an embedding groove31configured for embedding the cushioning device10, so the cushioning device10can be vertically embedded in the embedding groove31.

In this way, the cushioning device10is fitted and fixed to the inner wall of the receiving cavity to make the cushioning device10to be fixed relative to the inside wall of the receiving cavity30, thus the display panel fixed in the receiving cavity30is more stabilized, which will not generate a horizontal movement. The cushioning device10is embedded in the embedding groove31of the bottom of the receiving cavity30to prevent the cushioning device10from moving up and down in the receiving cavity30, prevent the display panel embedded in the cushioning device10from moving up and down, and remain stable in the receiving cavity30.

In one embodiment, as shown inFIG. 5, both two cushioning devices10are arranged on corners between the two side walls perpendicular to each other at the corner32of the receiving cavity30and the bottom of the receiving cavity30, respectively. In this way, the edges of both sides of the corner32of display panel can be embedded in the holding grooves15of the cushioning device10at the corner32of the receiving cavity30, thus four sides of the display are embedded in the cushioning device10, and each of the sides is corresponding to two cushioning devices10, thus the display panel can be firmly fixed in the receiving cavity30.

In one embodiment, as shown inFIG. 5, the corner32of the receiving cavity30further defines a semi-through hole321opposite to a center of the receiving cavity30, and an inside wall of the semi-through hole321and an inside wall of the receiving cavity30are connected with each other via a curved surface. In this way, when the display panel is received in the receiving cavity30, a pressure is transmitted from the cushioning device10to the inside wall of the receiving cavity30, thus the corner32of the receiving cavity30simultaneously bear two pressures vertical to each other. The two pressures simultaneously act on the corner32of the receiving cavity30, so a stress concentration, caused by the cracks of the corner32of the receiving cavity30, is prone to be formed on corner32of the receiving cavity30. However, the inner wall of the semi-through hole321of the corner32of the receiving cavity30and the inside wall of the receiving cavity30are connected with each other via a curved surface, thus it can eliminate the stress concentration, avoid that the corner32of the receiving cavity30forms cracks and crack, which bear two pressures vertical to each other, and significantly increase a stable service life of the display screen storage device40.

An embodiment of the present application further provides a display screen storage box, which includes a box body. The display screen storage box further includes a plurality of the above display screen storage devices40, and the plurality of the display screen storage devices40are sequentially stacked and arranged in the box body. A bottom of each of the display screen storage devices40defines an assembly bottom cavity411, and an assembly flange412correspondingly extends out from an edge of a top portion of each of the display screen storage devices40. In this way, the assembly flange412of the display screen storage devices40is embedded in the assembly bottom cavity411of the display screen storage devices40, thus the display screen storage devices40are stably stacked and arranged in the display screen storage box.

In the display screen storage box of the present application, the display screen storage devices40are sequentially stacked and arranged in the display screen storage box, thus efficient storage and protection of the plurality of the display screen storage devices40can be achieved.

The aforementioned embodiments are only preferred embodiments of the present application, and are not used for limiting the present application. Any modification, equivalent replacement, improvement, and so on, which are made within the spirit and the principle of the present application, should be included in the protection scope of the present application.
