A packaging structure

Abstract

This application provides a packaging structure, which includes a main body and a first folding part. The main body has an opening groove that extends through the main body along its length. A locking boss protrudes from the bottom wall of the opening groove and is located at one end of the main body along its length. The first folding part is rotatably connected to the end of the main body facing the locking boss and has a locking through hole. In the folded state, the locking boss engages with the locking through hole. Thus, when the first folding part is rotated to the closed state, the locking boss is inserted into the locking through hole to form a locking and locking mechanism, preventing structural wear caused by long-term friction. Moreover, the engagement between the locking boss and the locking through hole has a self-locking characteristic during transportation vibration, preventing accidental disengagement and thereby improving the protective effect of the packaging structure.

Description

Technical Field

[0001] This application relates to the field of packaging technology, and more particularly to a packaging structure. Background Technology

[0002] In packaging operations, products need to be packaged using packaging structures to protect them during transportation. Among related technologies, foldable packaging structures can be unfolded during transport for easy stacking. During packaging, multiple sides of the product are covered by folding to achieve better protection.

[0003] However, the relevant technology has the following drawbacks: the folding ears and the main body are usually locked together using an interference fit. This rigid fit is prone to wear on the contact surfaces due to repeated friction during long-term use, which can lead to loosening of the locking structure. Especially during transportation, when the product is subjected to continuous vibration or impact, the interference fit mechanical structure is prone to elastic deformation or displacement, resulting in locking failure.

[0004] Therefore, the relevant technologies urgently need to be improved to address the above problems. Utility Model Content

[0005] This application provides a packaging structure to at least solve the aforementioned problems in the related art.

[0006] To achieve the above objectives, this application provides the following technical solution: a packaging structure, the packaging structure comprising:

[0007] The main body is provided with an opening groove that extends through the length of the main body; a locking boss protrudes from the bottom wall of the opening groove and is located at one end of the main body along the length.

[0008] The first folding part is rotatably connected to the end of the main body facing the engaging boss and is provided with an engaging through hole; in the folded state, the engaging boss and the engaging through hole are engaged and connected.

[0009] In one embodiment, the top wall of the engaging boss is provided with a groove, and a first reinforcing part is provided in the groove.

[0010] In one embodiment, the first folding part is provided with a receiving groove, the end of the receiving groove facing the main body has an end wall, the end of the end wall away from the bottom wall of the receiving groove is connected to a supporting part, the supporting part is inclined relative to the end wall and has a locking through hole, the end of the supporting part away from the end wall is rotatably connected to the main body; in the folded state, the supporting part abuts against the main body.

[0011] In one embodiment, a second reinforcing portion is provided on the end wall.

[0012] In one embodiment, the supporting part is connected to the end wall via a stop part, the stop part being located between the supporting part and the end wall, and the hole wall at the end of the engaging through hole away from the main body extends to the stop part;

[0013] When folded, the engaging boss passes through the engaging through hole, and the stop abuts against the engaging boss to prevent the engaging boss from disengaging from the engaging through hole.

[0014] In one embodiment, at least one of the front wall, rear wall, or bottom wall of the opening groove is provided with a plurality of inwardly protruding first buffer protrusions, and the packaging structure abuts against the first side of the product to be packaged through the first buffer protrusions.

[0019] In the above packaging structure, by setting a locking boss at the end of the bottom wall of the opening slot, a mechanical locking connection is formed with the locking through hole on the first folding part, replacing the traditional interference fit locking method. When the first folding part is rotated to the closed state, the locking boss is embedded in the locking through hole to form a locking and locking, avoiding structural wear caused by long-term friction. Moreover, the locking connection between the locking boss and the locking through hole can have a self-locking retention characteristic during transportation vibration, preventing accidental disengagement, thereby improving the protective effect of the packaging structure.

[0029] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In related technologies, foldable packaging structures achieve locking and fixation through an interference fit between the folding lugs and the main body. However, this type of fit is prone to wear and tear on the contact surfaces due to friction during long-term use, causing the locking gap to gradually increase. During transportation, when the package is subjected to continuous vibration, the interference fit structure may unexpectedly detach due to material fatigue, leading to packaging failure. In a specific scenario involving electronic product packaging, when the transport vehicle traversed bumpy roads, insufficient locking force in the packaging structure caused the internal product to collide with the packaging box, resulting in surface scratches.

[0033] To address the aforementioned issues, researchers discovered that the root cause of failure in traditional interference fits lies in the irreversible wear characteristics of the friction contact surface. By attempting to introduce a forward locking mechanism into the packaging field, and after multiple experimental verifications, they determined that a through-hole structure should be set in the folding part to form a geometric constraint with the boss at a specific location on the main body.

[0034] Therefore, please combine Figure 1 and Figure 2 In some embodiments, this application proposes a packaging structure including a main body 11 and a first folding portion 13. The main body 11 has an opening slot 111 that extends through the length of the main body 11 and is used to receive the first side of the product to be packaged. A locking boss 12 protrudes from the bottom wall of the opening slot 111 and is located at one end of the main body 11 along its length. The first folding portion 13 is rotatably connected to the end of the main body 11 facing the locking boss 12 and has a locking through hole 135. The first folding portion is used to cover the second side of the product to be packaged. Figure 3 When folded, the engaging boss 12 engages with the engaging through hole 135. For example, the product to be packaged can be an electronic product, such as a laptop computer. Figure 1 This is a schematic diagram of the packaging structure in an embodiment of this application; Figure 2 for Figure 1 Enlarged view of section II in the middle; Figure 3 This is a schematic diagram of the packaging structure in the folded state in an embodiment of this application.

[0035] In the above packaging structure, by providing a locking boss 12 at the end of the bottom wall of the opening slot 111, a mechanical locking connection is formed with the locking through hole 135 on the first folding part 13, replacing the traditional interference fit locking method. When the first folding part 13 rotates to the closed state, the locking boss 12 is embedded in the locking through hole 135 to form a locking and locking, avoiding structural wear caused by long-term friction. Moreover, the locking connection between the locking boss 12 and the locking through hole 135 can have a self-locking retention characteristic during transportation vibration, preventing accidental disengagement, thereby improving the protective effect of the packaging structure.

[0036] Furthermore, the product to be packaged includes a first side, a second side, a third side, and a fourth side. For example, the product to be packaged can be a laptop computer, with the bottom edge of the laptop computer being the first side, the left and right side edges being the second and third sides, respectively, and the top edge being the fourth side.

[0037] In some preferred embodiments, the engaging boss 12 is a block structure with the bottom wall of the opening groove 111 protruding vertically. It is integrally formed with the main body 11 by in-mold injection molding to form an integral structure, thereby making the structure of the engaging boss 12 more robust.

[0038] In some alternative embodiments, a bendable connection is formed between the first folded portion 13 and the main body portion 11 by folding line indentation, so as to realize the rotational connection between the first folded portion 13 and the main body portion 11.

[0039] In some alternative embodiments, the first folding portion 13 and the main body portion 11 are rotatably connected by a pivot.

[0040] It should be noted that the connection method between the first folding part 13 and the main body part 11 listed above is merely an example, and this application does not limit the specific rotational connection method between the first folding part 13 and the main body part 11.

[0041] Please combine Figure 4 In some embodiments, the top wall of the engaging boss 12 is provided with a groove 121, and a first reinforcing part 122 is provided in the groove 121. The first reinforcing part 122 is fixed to the groove wall of the groove 121. This is to improve the overall strength of the engaging boss 12, thereby improving the fatigue resistance of the engaging boss 12 and extending the service life of the packaging structure. Moreover, the groove 121 structure forms a multi-directional buffer space on the top wall of the engaging boss 12, so as to absorb energy through deformation when subjected to external impact, thereby improving the protective effect. Figure 4 This is a schematic diagram of the structure of the main body 11 and the engaging boss 12 in this application.

[0042] In some alternative embodiments, the first reinforcing part 122 can be implemented by locally thickening, embedding reinforcing ribs, or providing corrugated protrusions.

[0043] Please combine Figure 5In some embodiments, the first folding portion 13 is provided with a receiving groove 131. The end of the receiving groove 131 facing the main body portion 11 has an end wall 132. A supporting portion 137 is connected to the end of the end wall 132 away from the bottom wall of the receiving groove 131. The supporting portion 137 is inclined relative to the end wall 132 and has a locking through hole 135. The end of the supporting portion 137 away from the end wall 132 is rotatably connected to the main body portion 11. The first folding portion 13 is rotatably connected to the main body portion 11 through the supporting portion 137. In the folded state, the supporting portion 137 abuts against the main body portion 11. Figure 5 This is a schematic diagram of the structure of the first folded part 13 in this application.

[0044] During the folding process, an external force is applied to the first folding part 13, which causes the end wall 132 and the supporting part 137 to rotate relative to the main body part 11 until the supporting part 137 abuts against the main body part 11. At this time, the first folding part 13 enters the folded state. At the same time, during the folding process, the supporting part 137 first undergoes elastic deformation and guides the engaging boss 12 into the engaging through hole 135 through its own tilt angle, and makes the engaging boss 12 penetrate through the engaging through hole 135. Then, the restoring force generated by the elastically deformed supporting part 137 causes the hole wall at the end of the engaging through hole 135 away from the main body part 11 to press against the engaging boss 12, so that the engaging boss 12 is firmly engaged in the engaging through hole 135, thereby effectively preventing the engagement from loosening.

[0045] Please combine Figure 5 In some embodiments, the main body 11 is provided with a support portion 113 at one end facing the first folding portion 13. The support portion 113 is inclined relative to the extending direction of the main body 11 and cooperates with the abutment portion 137. In the folded state, the abutment portion 137 abuts against the support portion 113 on the main body 11.

[0046] In some preferred embodiments, the included angle between the supporting portion 137 and the end wall 132 is 30°-60°; the included angle between the supporting portion 113 and the extending direction of the main body portion 11 is 30°-60°.

[0047] In some preferred embodiments, the included angle between the support portion 113 and the abutment portion 137 is 90°, which is the maximum rotation angle of the first folding portion 13.

[0048] In some embodiments, a second reinforcing portion 136 is provided on the end wall 132 to enhance the strength of the end wall 132, thereby improving the fatigue resistance of the end wall 132 and extending the service life of the packaging structure.

[0049] In some alternative embodiments, the second reinforcement 136 is achieved by locally thickening, embedding reinforcing ribs, or providing corrugated protrusions.

[0050] Please combine Figure 5 In some embodiments, the supporting portion 137 is connected to the end wall 132 via a stop portion 133, which is located between the supporting portion 137 and the end wall 132. The wall of the engaging through hole 135 at the end away from the main body 11 extends to the stop portion 133, so that the stop portion 133 forms the wall of the engaging through hole 135 at the end away from the main body 11. In the folded state, the engaging boss 12 passes through the engaging through hole 135, and the stop portion 133 abuts against the engaging boss 12 to prevent the engaging boss 12 from disengaging from the engaging through hole 135.

[0051] Thus, when the first folding part 13 rotates around the main body 11 to the folded state, the engaging boss 12 passes through the engaging through hole 135, while the stop part 133 extends to the back side of the engaging boss 12 to form a reverse blockage. When an external force is applied to the engaging structure, the stop part 133 forms a larger contact surface with the back side of the engaging boss 12, avoiding excessive pressure concentration and thus better limiting the displacement tendency of the engaging boss 12. Therefore, the engaging structure and the stop part 133 form a two-way lock, preventing the engaging boss 12 from slipping out of the engaging through hole 135 and preventing the first folding part 13 from rebounding due to vibration.

[0052] In some embodiments, the overlap height between the stop portion 133 and the engaging boss 12 is 4mm to 8mm. Thus, when the overlap height between the stop portion 133 and the engaging boss 12 is less than 4mm, sufficient contact area cannot be provided, resulting in poor pressure dispersion. When the overlap height between the stop portion 133 and the engaging boss 12 is greater than 8mm, the height of the engaging boss 12 becomes too large, making folding difficult. When the overlap height between the stop portion 133 and the engaging boss 12 is 4mm to 8mm, sufficient contact area is provided to disperse pressure while avoiding difficulties in folding due to excessive height.

[0053] It is understood that the overlap height refers to the length of the vertical overlap area between the stop 133 and the engaging boss 12 in the folded state. Specifically, this can be achieved by adjusting the extension length of the stop 133 to match the thickness of the engaging boss 12.

[0054] Please combine Figure 4 In some embodiments, at least one of the front wall, rear wall or bottom wall of the opening groove 111 is provided with a plurality of inwardly protruding first buffer protrusions 112, and the packaging structure abuts against the first side of the product to be packaged through the first buffer protrusions 112.

[0055] Thus, during the packaging structure assembly process, when the product to be packaged is placed into the opening slot 111, the first buffer protrusion 112 contacts the first side of the product to be packaged and generates elastic deformation, forming a multi-point distributed contact area to buffer and protect the product to be packaged; through the friction between the first buffer protrusion 112 and the product surface, the displacement of the product to be packaged caused by vibration during transportation is limited; at the same time, the distribution design of the first buffer protrusion 112 makes the contact pressure evenly distributed, avoiding local stress concentration that could cause damage to the surface of the product to be packaged.

[0056] In some alternative embodiments, the plurality of inwardly protruding first buffer protrusions 112 refer to local bulge structures extending from the inner surface of the tank to the interior. These protrusions can be formed by local deformation of the material or by adding elastic material. The distribution density and height of the first buffer protrusions 112 are adjusted according to the product size to generate appropriate contact pressure.

[0057] Please combine Figure 5 In some embodiments, at least one of the front wall, rear wall or bottom wall of the receiving groove 131 is provided with a plurality of inwardly protruding second buffer protrusions 134, and the packaging structure abuts against the second side of the product to be packaged through the second buffer protrusions 134.

[0058] Thus, during the packaging structure assembly process, when the product to be packaged is placed into the opening slot 111, the second buffer protrusion 134 contacts the second side of the product to be packaged and generates elastic deformation, forming a multi-point distributed contact area to buffer and protect the product to be packaged; through the friction between the second buffer protrusion 134 and the product surface, the displacement of the product to be packaged due to vibration during transportation is limited; at the same time, the distribution design of the second buffer protrusion 134 makes the contact pressure evenly distributed, avoiding local stress concentration that could cause damage to the product surface.

[0059] In some alternative embodiments, the multiple inwardly protruding second protrusions refer to localized raised structures extending from the inner surface of the groove inward. These protrusions can be formed by localized deformation of the material or by adding elastic material. The distribution density and height of the second buffer protrusions 134 are adjusted according to the product size to generate appropriate contact pressure.

[0060] Please combine Figure 3 In some embodiments, the packaging structure further includes a second fold 14, which is rotatably connected to the other end of the main body 11 and has the same structure and size as the first fold 13. The second fold 14 is used to cover the third side of the product to be packaged. The other end of the main body is also provided with a locking boss 12, through which the second fold 14 is locked and connected to the main body 11.

[0061] Thus, the two ends of the main body 11 are respectively connected to the first folding part 13 and the second folding part 14. In the folded state, the two folding parts are symmetrically engaged with the engaging bosses 12 at both ends of the main body 11 through the engaging through holes 135. Since the first folding part 13 and the second folding part 14 on both sides adopt the same structure and size, the packaging structure is evenly stressed on both sides when closed, avoiding engagement failure due to wear on one side. At the same time, the first folding part 13 and the second folding part 14 cover the second and third sides of the product to be packaged, forming a clamping effect on the product to be packaged. This can balance the force on the product to be packaged in the length direction of the main body during transportation, reducing the risk of product displacement due to unilateral fixation failure.

[0062] In some embodiments, the main body 11, the first folding portion 13, and the second folding portion 14 are an integral structure.

[0063] Thus, during the folding process, the second folding part 14 and the first folding part 13 rotate around the main body 11 simultaneously and are locked together by the engaging through hole 135 and the engaging boss 12. Since the main body 11 and the two folding parts are integrally molded, it is beneficial to eliminate the seams of separate assembly and reduce weak points at the connection.

[0064] In some embodiments, the main body 11, the first folding portion 13, and the second folding portion 14 are all made of paper-plastic material. Paper-plastic material refers to a composite material formed through pulp molding, specifically achieved by mixing recycled pulp with biodegradable resin and then hot-pressing it. Paper-plastic material possesses a certain degree of elasticity and toughness. Thus, by using paper-plastic material, stress can be absorbed through elastic deformation during the folding and locking process, preventing surface wear of the workpiece to be packaged caused by rigid materials.

[0065] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
