[0002] In related technologies, small and medium-sized display products are mostly packaged and transported using trays. During storage and transportation, the sliding of the packaging can cause the display product to move in the x, y, and z directions within the tray, resulting in direct contact between the display product and the tray. Due to the low rigidity, low scratch resistance, and low brittleness of these products, deformation, scratches, and breakage are common problems. Utility Model Content

In the drawings, the thickness of layers and regions is enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Therefore, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes.

[0036] Figure 1 This is a packaging rendering of a product packaged using existing pallets, such as... Figure 1 As shown, the pallet has a central slot for holding products, surrounded by T-shaped protrusions. These T-shaped protrusions serve to position and space products, preventing compression when multiple pallets are stacked. However, this pallet structure is still insufficient in preventing product slippage, especially during transport when subjected to bumps or sudden braking, where products can easily shift within the pallet. Figure 1 The tilting displacement shown can cause a collision with the pallet or adjacent products, resulting in product deformation or damage.

[0037] In view of this, the present disclosure provides a packaging structure for packaging products, which can effectively prevent the products from sliding or shifting during transportation. Figure 2 This is a structural diagram of the packaging structure, such as... Figure 2 As shown, the packaging structure includes at least two trays 1 stacked along its thickness direction and at least one protective component 2 disposed within the trays 1.

[0038] Figure 3 A schematic diagram of the specific structure of the pallet, such as Figure 2-3 As shown, the tray 1 includes a support portion 101 and a protrusion 102 disposed around the support portion 101. The bottoms of the support portion 101 and the protrusion 102 are located on the same plane, and the protrusion 102 protrudes towards the support portion 101 along its thickness. The protrusion 102 includes a first sidewall and a second sidewall disposed opposite to each other. The first sidewall is closer to the support structure 101 than the second sidewall. The first sidewall and the support portion define a first receiving space for placing a protective component 2, such as... Figure 2 As shown. For example, the dihedral angle formed by the first sidewall and the support portion 101 can be a right angle or an obtuse angle. That is, the diameter of the first accommodating space can remain unchanged, or gradually increase in the direction away from the support portion 101.

[0039] Continue to refer to Figure 3The pallet 1 also includes multiple limiting grooves 103 / 105 disposed on the first sidewall of the protrusion 102. Each limiting groove is provided with a positioning element 104 / 106. The limiting grooves and positioning elements cooperate to achieve positioning of multiple pallets. The multiple limiting grooves are divided into multiple first limiting grooves 103 and multiple second limiting grooves 105, with the depth of the first limiting grooves 103 being less than the depth of the second limiting grooves 105. Correspondingly, for ease of distinction, the positioning element disposed in the first limiting groove 103 is referred to as the first positioning element 104, and the positioning element disposed in the second limiting groove 105 is referred to as the second positioning element 106.

[0040] In a specific example, continue to refer to Figure 3 The bottom surface of the first limiting groove 103 is coplanar with the supporting part 101. That is, the depth of the first limiting groove 103 is equal to the protrusion height of the protrusion 102. This ensures that the first positioning member 104, provided in the first limiting groove 103, protrudes from the supporting part 101, thus facilitating the fixing of the protective component 2. The fixing method of the protective component 2 will be described in detail below. The height of the first positioning member 104 can be equal to the depth of the first limiting groove 103, that is, equal to the protrusion height of the protrusion 101.

[0041] Continue to refer to Figure 3 The depth of the second limiting groove 105 is greater than the depth of the first limiting groove 103. This means that the bottom surface of the second limiting groove 105 is not on the same plane as the supporting part 101, and the bottom surface of the second limiting groove 105 is located on the side of the supporting part 101 opposite to the first positioning member 104. Furthermore, the height of the second positioning member 106 located in the second limiting groove 105 is less than or equal to the distance between the bottom surface of the second limiting groove 105 and the plane where the supporting part 101 is located. This means that the second positioning member 106 does not protrude from the supporting part 101 at all. Thus, it can be ensured that the protective component 2 located in the first accommodating space can be placed completely horizontally, and will not be disturbed during the transportation of the packaging box due to the protrusion of the second positioning member 106.

[0042] Thus, taking the plane where the bearing part 101 is located as the reference plane, for each pallet 1, it includes a first insertion structure and a second insertion structure protruding on two opposite sides of the reference plane. The first insertion structure is composed of a first limiting groove 103 and a first positioning member 104 disposed in the first limiting groove 103, and the second insertion structure is formed by a second limiting groove 105 and a second positioning member 106 disposed in the second limiting groove 105. Figure 4 For use Figure 2 The diagram shown is a cross-sectional view of the packaging structure after the product has been packaged. (Refer to...) Figure 2 and Figure 4For two adjacent pallets 1 in the entire packaging structure, the downward-protruding second interlocking structure of the upper pallet can be interlocked with the upward-protruding first interlocking structure of the lower pallet, forming a secure connection. In this way, multiple pallets can be stacked upwards indefinitely to form a packaging structure that can transport multiple products.

[0043] Continue to refer to Figure 2-4 To achieve relative fixation of the first and second insertion structures, the width w1 of the first limiting groove 103 along the circumferential direction of the supporting portion 101 is greater than the width w2 of the second limiting groove 105 along the circumferential direction of the supporting portion. Thus, the second limiting groove 105 can be embedded within the first limiting groove 103. Furthermore, the first positioning member 104 is either hollow or solid, and the second positioning member 106 is hollow. The outer diameter of the first positioning member 104 is less than or equal to the outer diameter of the second positioning member 106. Thus, when the second limiting groove 105 is embedded within the first limiting groove 103, the first positioning member 104 can be engaged with the second positioning member 106, thereby achieving a stable connection between the first and second insertion structures. For example, for the engaged first fixing member 104 and the second fixing member 106, the height d3 of the overlapping portion along the thickness direction of the packaging structure is greater than or equal to 3mm. This ensures that the first positioning member 104 and the second positioning member 106 are firmly engaged and prevents detachment.

[0044] It should be noted that for three adjacent pallets in the packaging structure (for ease of explanation, the three pallets stacked from bottom to top will be referred to as pallet a, pallet b, and pallet c), in order to achieve relative fixation, for the first limiting groove 103 and the first positioning element 104 in pallet b, the corresponding positions in pallet c are provided with corresponding second limiting grooves 105 and second positioning elements 106; for the second limiting groove 105 and the second positioning element 106 in pallet b, the corresponding positions in pallet a are provided with corresponding first limiting grooves 103 and first positioning elements 104. It can be seen that pallets a and c are both corresponding to pallet b. Therefore, at the position corresponding to the first limiting groove 103 of pallet b, both pallets a and c can be provided with second limiting grooves 105; and at the position corresponding to the second limiting groove 105 of pallet b, both pallets a and c can be provided with first limiting grooves 103. In this way, pallets a and c can be made to have exactly the same shape and be manufactured using the same mold, thus reducing costs. Of course, in order to adapt to different products or meet different transportation requirements, all pallets in the packaging structure can be designed in different shapes, and the limiting grooves in each pallet can also be set as third limiting grooves with different depths or shapes than the first and second limiting grooves. This disclosure does not limit this.

[0045] In one example, the multiple pallets in the packaging structure are divided into at least one first pallet and at least one second pallet, and the first pallet and the second pallet are stacked alternately in sequence. Figure 7 This is a schematic diagram of the structure of the first tray. Figure 8 This is a schematic diagram of the second pallet. For example, for the entire packaging structure, the first pallet is the first first pallet, the second pallet is the first second pallet, the third pallet is the second first pallet, the fourth pallet is the second second pallet, the fifth pallet is the third first pallet, and so on. The 2N-1th pallet is the Nth first pallet, and the 2Nth pallet is the Nth second pallet; N is a positive integer. Wherein, the first limiting groove 103 of the i-th first tray is embeddedly connected to the second limiting groove 105 of the i-th second tray, and the first positioning member 104 of the i-th first tray is engaged in the second positioning member 106 of the i-th second tray; the second limiting groove 105 of the i-th first tray is embeddedly connected to the first limiting groove 103 of the (i-1)-th second tray, and the first positioning member 104 of the (i-1)-th second tray is engaged in the second positioning member 106 of the i-th first tray; the first limiting groove 103 of the i-th second tray is embeddedly connected to the second limiting groove 105 of the (i+1)-th first tray, and the first positioning member 104 of the i-th second tray is engaged in the second positioning member 106 of the (i+1)-th first tray; the second limiting groove 105 of the i-th second tray is embeddedly connected to the first limiting groove 103 of the i-th first tray, and the first positioning member 104 of the i-th first tray is engaged in the second positioning member 106 of the i-th second tray; where i is an integer greater than or equal to 2.

[0046] For example, to facilitate differentiation and use, the first and second trays are also provided with different identification symbols. For example, such as... Figure 7-8 As shown, the first tray can be marked with "A" or "①", and the second tray can be marked with "B" or "②". Of course, the first and second trays can also use other easily distinguishable symbols, and this disclosure does not impose any restrictions on this. Furthermore, the first and second trays can be set to different colors for easy differentiation.

[0047] In some examples, continue to refer to Figure 7-8To evenly distribute the force, multiple first limiting grooves 103 and multiple second limiting grooves 105 on the first pallet are alternately arranged along the circumference of the supporting part 101, and the limiting grooves on the two opposite sides of the supporting part 101 are symmetrically arranged. Correspondingly, the multiple first limiting grooves 103 and multiple second limiting grooves 105 on the second pallet are also alternately arranged along the circumference of the supporting part 101. In this way, when multiple pallets are stacked, the force borne by each pallet can be more evenly distributed to the surrounding area through the alternately arranged limiting grooves, improving the stability and load-bearing capacity of the entire packaging structure. At the same time, this alternating arrangement can also enhance the tightness of the connection between pallets, reducing the risk of pallet separation due to bumps or vibrations during transportation.

[0048] The following describes the specific structure of the protective component 2 in the packaging structure, as well as the fixing method between the protective component 2 and the positioning parts 104-106.

[0049] like Figure 2 and Figure 4 As shown, the protective component 2 includes a first protective layer 201 and a second protective layer 202 arranged sequentially along the thickness direction of the packaging structure, and a first distance d1 is provided between the first protective layer 201 and the second protective layer 202. This first distance d1 causes the first protective layer 201 and the second protective layer 202 to define a product slot for placing the product 3. It should be noted that the product 3 in this disclosure includes, but is not limited to, any one of ultra-thin flexible products, ultra-thin glass-based products, flexible products, and conventional display products.

[0050] In some examples, the first protective layer 201 and the second protective layer 202 may be made of materials such as polyethylene terephthalate (PET), polyethylene (PE), high-density polyethylene (HDPE), polypropylene (PP), and polyvinyl chloride (PVC). The shapes of the first protective layer 201 and the second protective layer 202 can be designed according to the shape of the packaged product 3. For example, for rectangular products, the first protective layer 201 and the second protective layer 202 can be designed as corresponding rectangular structures to ensure that the product can be stably placed in the product slot.

[0051] In some examples, refer to Figure 2 and Figure 4 The protective component 2 further includes a plurality of buffer members 203 disposed between the first protective layer 201 and the second protective layer 202. The buffer members 203 are located at the edges of the first protective layer 201 and the second protective layer 202 and are used to define the first distance d1. For example, the buffer members 203 may be made of expandable polyethylene (EPE), expanded polypropylene (EPP), polystyrene foam (EPS), ethylene-vinyl acetate copolymer (EVA), or rubber. The thickness of the buffer members 203 is consistent with the thickness of the product, thus providing support and preventing the product from being subjected to excessive pressure.

[0052] In some examples, continue to refer to Figure 2 and Figure 4 The protective component 2 also includes a plurality of first through holes 208 that sequentially penetrate the first protective layer 201, the buffer member 203, and the second protective layer 202 along its thickness direction. Each first through hole 208 is sleeved and connected to a first positioning member 104. In this way, the protective component 2 can be fixed in the horizontal direction by the first positioning member 104, ensuring that the product will not undergo excessive displacement in the horizontal direction (i.e., the x and y directions) during transportation. Furthermore, since each first positioning member 104 is engaged with a second positioning member 106, and the second limiting groove 105 corresponding to the second positioning member 106 is embedded in the first limiting groove 103 corresponding to the first positioning member 104, the second limiting groove 105 and the second positioning member 106 can press the protective component 2 tightly, preventing the protective component 2 from displacing in the vertical direction (i.e., the z direction). Thus, through the cooperation of the protective component 2, the first positioning element 104, the second positioning element 106, the first limiting groove 103, and the second limiting groove 105, the product can be securely fixed in all directions within the packaging structure, effectively resisting the impact of bumps, vibrations, or sudden braking that may be encountered during transportation. This design not only greatly reduces the risk of the product colliding with the pallet or adjacent products due to sliding or displacement, thereby avoiding product deformation or damage, but also significantly improves the overall stability and reliability of the packaging structure.

[0053] In some examples, refer to Figure 4 For the first through hole 208 and the first positioning member 104 that are connected by a sleeve, a second distance d2 is provided between the side wall of the first positioning member 104 and the inner wall of the first through hole 208. This second distance d2 provides a buffer space to prevent excessive stress from mutual compression between the first positioning member 104 and the first through hole 208 during transportation, in case of minor deformation caused by vibration or temperature changes, thus avoiding damage to the protective component 2 or the product. The specific value of this second distance can be determined comprehensively based on factors such as the product's material, size, and the maximum vibration amplitude that may be encountered during transportation. For example, for fragile or precision products, the second distance can be appropriately increased to provide more sufficient buffer space; while for products with a stable structure that are not easily damaged, the second distance can be relatively reduced to make the packaging structure more compact while ensuring product safety.

[0054] To further ensure the stability of the product during transportation, the protective component 2 also includes a first adhesive layer 204, a second adhesive layer 205, a third adhesive layer 206, and a fourth adhesive layer 207.

[0055] Among them, such as Figure 4 and Figure 5 As shown, the first adhesive layer 204 is disposed between the first protective layer 201 and the product 3, and the second adhesive layer 205 is disposed between the second protective layer 202 and the product. The first adhesive layer 204 and the second adhesive layer 205 can enhance the friction between the product and the first protective layer 201 and the second protective layer 202, preventing the product from shifting due to shaking. For example, the first adhesive layer 204 and the second adhesive layer 205 can be of a type with high adhesion and low residue, such as some special pressure-sensitive adhesives or double-sided tapes. This ensures a stable fixation while also facilitating product removal and reuse of the packaging structure.

[0056] Reference Figure 4 and Figure 6 The third adhesive layer 206 is disposed between the first protective layer 201 and the buffer 203, and the fourth adhesive layer 207 is disposed between the second protective layer 202 and the buffer 203. Both the third adhesive layer 206 and the fourth adhesive layer 207 are double-sided adhesives. The viscosity of the surface of the third adhesive layer 206 in contact with the buffer 203 is greater than the viscosity of the surface in contact with the first protective layer 201, and the viscosity of the surface of the fourth adhesive layer 207 in contact with the buffer 203 is greater than the viscosity of the surface in contact with the second protective layer 202. This arrangement allows the buffer 203 to be easily peeled off from the first and second protective layers 201, facilitating replacement or adjustment of the buffer 203. Simultaneously, it ensures a stable connection between the buffer 203 and the protective layers during normal use, preventing the buffer 203 from loosening and affecting the protective effect on the product.

[0057] In some examples, such as Figure 3 As shown, the support portion 101 is also provided with a plurality of first grooves 107 extending partially through its thickness direction, and reinforcing ribs 108 disposed within the first grooves 107. The reinforcing ribs 108 effectively enhance the structural strength of the support portion 101, making it less prone to deformation or damage when bearing the weight of the product and various external forces that may arise during transportation. The plurality of first grooves 107 are evenly distributed on the support portion 101, and the reinforcing ribs 108 are tightly embedded within the first grooves, forming a stable integral structure with the support portion 101. This design not only improves the load-bearing capacity of the support portion 101, but also reduces the overall weight of the pallet to a certain extent, thereby reducing transportation costs.

[0058] The shape of the first groove 107 can be designed in various ways according to actual needs, such as rectangular, trapezoidal, or arc-shaped. The way the first groove 107 and the reinforcing rib 108 are matched will also differ depending on the shape, but all will achieve the purpose of enhancing structural strength. When the first groove 107 is designed as rectangular, the reinforcing rib 108 can fit tightly against the inner wall of the groove, forming a regular reinforced structure. If it is designed as trapezoidal, the contact area between the reinforcing rib 108 and the groove will change, which may be more conducive to stress dispersion while ensuring strength. An arc-shaped first groove 107, combined with a reinforcing rib 108 of corresponding curvature, allows the load-bearing part 101 to better transmit force to the surrounding area when subjected to external forces. Furthermore, the depth of the first groove 107 can also be selected in various ways. A deeper depth allows the reinforcing rib 108 to be embedded deeper, providing stronger support for the load-bearing part 101, but may increase the difficulty of pallet manufacturing; a shallower depth makes manufacturing relatively easier, but the reinforcement effect on the load-bearing part 101 will be slightly weaker. In practical applications, the product weight, transportation environment and manufacturing cost need to be comprehensively considered, and the appropriate shape and depth of the first groove 107 need to be flexibly designed.

[0059] In some examples, continue to refer to Figure 3 The supporting part 101 is rectangular in shape, and the protrusion 102 surrounding the supporting part 101 has a rectangular ring as its orthographic projection on the plane of the supporting part 101. In addition to multiple limiting grooves, the protrusion 102 of the rectangular ring also includes four buffer grooves 109. The buffer grooves 109 are located at the four apex corners of the rectangular ring protrusion 102 and the rectangular supporting part 101. The shape of the buffer grooves 109 on the plane of the supporting part 101 includes, but is not limited to, rectangles, squares, circles, or triangles. By providing the buffer grooves 109, the impact forces on the apex corners of the protective component 2 during transportation, which could cause product damage, can be absorbed and dispersed.

[0060] In some examples, pallet 1 can be made of materials such as polyethylene terephthalate (PET), polystyrene (PS), polypropylene (PP), or ABS plastic. PET offers good transparency, mechanical properties, and chemical resistance, allowing for clear product display and withstanding certain external forces, while remaining resistant to common chemicals. Polystyrene (PS) is lightweight, easy to process, and relatively inexpensive, facilitating large-scale pallet production. Polypropylene (PP) boasts high strength and heat resistance, maintaining stable performance at high temperatures, making it suitable for transporting products with specific temperature requirements. ABS plastic offers excellent overall performance, combining toughness, hardness, and rigidity, with strong impact resistance, effectively protecting products from collision damage during transport. Depending on the characteristics of the packaged products, the transportation environment, and cost budget, suitable materials can be flexibly selected to manufacture pallets, ensuring the packaging structure effectively protects the products while remaining economical and practical.

[0061] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto.
