Description

Technical Field

[0001] The present application relates to the field of packaging, and in particular to a packaging structure. Background Art

[0002] Currently, electronic devices are prone to violent transport events such as drops and bumps in complex logistics environments. Due to the encased packaging structure, it is difficult to identify damage to electronic devices after such transport. This can lead to on-site returns of electronic devices upon arrival, resulting in losses for both the user and the seller. Summary of the Invention

[0003] The embodiments of the present application provide a packaging structure that can effectively record violent transportation behaviors in logistics, thereby preventing electronic products from being damaged during transportation and causing losses to both users and sellers.

[0004] In the first aspect, the present application provides a packaging structure, which includes a trough body and a detection groove; the trough body is formed by a depression on the outer surface of the packaging structure; the trough body includes at least two groove walls; the detection groove is arranged on the groove wall of the trough body; the detection groove is used to generate an indication of the falling of the packaging structure; the setting position of the detection groove is the stress risk position of the trough body; wherein the strain value of the stress risk position is greater than or equal to a preset strain threshold.

[0005] It is understandable that when the packaging structure is subjected to external forces during transportation, the electronic equipment protected by the packaging structure will be at risk of damage. In order to identify whether the damage to the electronic product is caused by violent transportation, the present application sets a detection slot at the stress risk position of the slot body. In the prior art, the structure of the slot body of the packaging structure is relatively stable, and the slot body is not easily damaged or cracked when subjected to external forces, making it impossible to identify whether the packaging structure has been subjected to violent transportation. By setting a detection slot at the stress risk position of the slot body, the present application can make the detection slot crack when the packaging structure is subjected to a certain amount of external force, resulting in visible cracks, thereby intuitively identifying whether the packaging material and the electronic equipment it protects have been subjected to violent transportation.

[0006] In a possible implementation, the detection groove passes through the packaging structure along a thickness direction of the packaging structure.

[0007] In a possible implementation manner, the detection groove is a rectangular parallelepiped groove; and the size of the detection groove is determined based on the material of the packaging structure and the external force applied to the packaging structure.

[0008] In one possible embodiment, the size of the detection groove satisfies the following relationship: L=C*D / 2; wherein L is the length of the detection groove; C is the stress concentration coefficient, and the stress concentration coefficient C=A / B; A is the maximum stress value that the material of the packaging structure can withstand; B is the stress value at the stress risk position when the packaging structure is subjected to external force; and D is the preset width of the detection groove.

[0009] It is understandable that the strength of packaging structures made of different materials is different. By determining the shape of the detection groove in combination with the strength of the material and the different stress values at the stress risk position, the size of the external force that the detection groove can withstand can be adjusted so that the detection groove will only crack when the external force reaches a level that will damage the electronic equipment, thereby producing visible cracks.

[0010] In a possible implementation manner, a ratio of the length L of the detection slot to the width D of the detection slot is greater than or equal to 500.

[0011] It is understood that when the ratio of the length to the width of the detection slot is greater than or equal to 500, the detection slot can be structured like a narrow slit. When subjected to an external force exceeding a certain magnitude, the packaging structure is prone to cracking, and the crack direction is likely to extend along the direction of the slit. This achieves the purpose of identifying violent transportation through the packaging structure.

[0012] In a possible embodiment, the packaging structure further includes a marking line; the marking line is arranged on the outside of the detection slot; the marking line and the detection slot are spaced apart; the marking line is used to determine whether the external force applied to the packaging structure exceeds an external force threshold.

[0013] It is understood that when the packaging structure is subjected to a certain amount of external force, cracks will appear in the inspection slot. As the external force on the packaging structure increases, the length of the crack will also increase. When the crack extends to a certain length, it can be determined that the external force on the packaging structure is too great, and the electronic equipment inside may have been damaged due to violent transportation. The setting of the marking line can make the extension length of the crack more intuitive. When the crack exceeds the marking line, it can be considered that the external force on the packaging structure exceeds the safe value. If the internal electronic equipment is damaged, it can be determined that the damage was caused by violent transportation.

[0014] In a possible implementation, the detection groove is used to generate a crack when the packaging material falls; if the crack intersects the marking line, it is determined that the external force of the packaging structure exceeds the external force threshold.

[0015] It is understood that if a crack extends from one end of the detection slot away from the slot and the crack extends only a short distance, short of reaching the marking line, it indicates that the external force exerted on the packaging material is insufficient to damage the electronic device. However, if the crack extends a long distance and intersects the marking line, it indicates that the external force exerted on the packaging material is excessive, posing a risk of damaging the electronic device, thus indicating that the packaging material has been subjected to violent transportation.

[0016] In one possible embodiment, the slot body includes a through-groove extending through the packaging structure along its thickness, and the detection slot is disposed on a wall of the through-groove. It is understood that the through-groove weakens the structural strength of the packaging structure, and the area surrounding the through-groove is a stress risk location.

[0017] In a possible implementation, there are a plurality of detection slots; the plurality of detection slots are spaced apart on the slot wall; and the intervals between the plurality of detection slots are greater than or equal to a preset distance.

[0018] In a possible implementation, the trough body further includes a stretched net; the stretched net includes a plurality of meshes and a plurality of edges; each of the edges is provided between two adjacent meshes; and the detection slot is provided on the edge.

[0019] It is understandable that the edges of the stretched mesh structure have relatively weak structural strength because both sides are mesh holes. Setting a detection groove at the edge position can easily identify whether it is subjected to external forces exceeding the safety value. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] For ease of understanding, the terms involved in the embodiments of the present application are first explained.

[0039] And / or: It is just a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0040] Multiple: refers to two or more than two.

[0041] Connection: should be understood in a broad sense. For example, A and B are connected, which can be either directly connected or indirectly connected through an intermediary.

[0042] The specific implementation of the present application will be clearly described below with reference to the accompanying drawings.

[0043] Embodiments of the present application provide a packaging structure. This packaging structure is used to wrap around the periphery of electronic devices, protecting them from direct impact during transportation. This packaging structure can also effectively record any violent transportation behaviors during device transportation, reducing costs associated with damage to the equipment during such incidents.

[0044] The electronic device may be, but is not limited to, a server, a router, a switch, a supercomputer, an AI (Artificial Intelligence) device, or an in-vehicle device, etc. The following description will take the electronic device as an example, but it should be understood that the present invention is not limited to this.

[0045] See also Figure 1 , Figure 1 1 is a schematic diagram of an embodiment of the present application providing a packaging structure 1000 for protecting an electronic device A, and a schematic diagram of the structure of the electronic device packaging structure 1000 and the electronic device A in cooperation. In this schematic diagram, the packaging structure 1000 of the electronic device A may include a first packaging structure 100 and a second packaging structure 200. The first packaging structure 100 and the second packaging structure 200 may respectively cover opposite sides of the electronic device A, thereby protecting the electronic device A during the logistics and transportation of the electronic device A. Specifically, during the logistics and transportation process, the first packaging structure 100 may cover the top surface of the electronic device A, and the second packaging structure 200 may cover the bottom surface of the electronic device A. The bottom surface of the electronic device A may be the side of the server where the motherboard is provided.

[0046] For example, the packaging structure 1000 may further include two first packaging structures 100 , which respectively cover opposite sides of the electronic device A. Alternatively, the packaging structure 1000 may further include two second packaging structures 200 , which respectively cover opposite sides of the electronic device A.

[0047] In the embodiment of the present application, the packaging structure 1000 is taken as an example to describe the packaging structure. The length direction of the packaging structure 1000 is Figure 1 The direction marked with X in the figure is the width direction of the packaging structure 1000. Figure 1 The direction marked by Y in FIG. 1 is the thickness direction of the packaging structure 1000. Figure 1 In the direction marked by Z, the X direction, Y direction and Z direction are perpendicular to each other.

[0048] The packaging structure 1000 has at least one trough ( Figure 1 Not marked), the trough body includes at least two trough walls. The trough body can be formed by a depression on the outer surface of the packaging structure 1000, and the trough body may or may not penetrate the packaging structure 1000. Specifically, the trough body can include a through groove and a groove. Among them, the through groove can be a trough body that penetrates the packaging structure 1000 along the Z direction. The groove can be a trough body formed by a depression on the outer surface of the packaging structure 1000 and does not penetrate the packaging structure 1000. The groove can specifically be a notch, a surface groove, a decorative groove, or a mesh of a net structure as described below. The packaging structure 1000 also has one or more detection grooves 1001. The detection groove 1001 can be a rectangular groove. Alternatively, the detection groove can be an arc-shaped groove. When the packaging structure 1000 has only one detection groove 1001, the detection groove 1001 can be provided on the groove wall of the trough body of the first packaging structure 100 or the second packaging structure 200. The detection groove 1001 is used to generate an indication that the packaging structure 1000 has fallen. When the packaging structure 1000 has multiple detection slots 1001, the multiple detection slots 1001 can be located in the first packaging structure 100 and / or the second packaging structure 200. The multiple detection slots 1001 include at least one first detection slot and at least one second detection slot. The first detection slot can be located in the first packaging structure 100, and the second detection slot can be located in the second packaging structure 200. The multiple detection slots 1001 are spaced apart along the edge of at least one slot. Each detection slot 1001 is located at a stress-risk location on the slot, where the strain value experienced at the stress-risk location is greater than or equal to a preset strain threshold. The preset strain threshold can be 4000 ε. A stress-risk location is a location where the slot experiences a strain value greater than or equal to 4000 ε when the packaging structure 1000 is subjected to an external force. When the strain value experienced by the slot is greater than or equal to 4000 ε, it indicates that the electronic device A protected by the packaging structure 1000 is subjected to excessive external force. Excessive external force may cause damage to the electronic device A. Each detection groove 1001 is connected to the groove body, and each detection groove 1001 penetrates the packaging structure 1000 along the Z direction. The detection groove 1001 is used to generate cracks when the packaging structure 1000 is subjected to external force.

[0049] It is understandable that when the packaging structure 1000 is subjected to external forces during transportation, the electronic device A protected by the packaging structure 1000 is at risk of damage. However, in the prior art, the structure of the trough body of the packaging structure is relatively stable, and the trough body is not easily damaged or cracked when subjected to external forces, making it impossible to identify whether the packaging structure has been subjected to violent transportation. In order to distinguish whether the damage to the electronic product A is caused by violent transportation, the present application sets a detection groove 1001 at the stress risk position of the trough body, so that when the packaging structure 1000 is subjected to a certain amount of external force, the detection groove 1001 will crack, resulting in visible cracks, so that it can be intuitively distinguished whether the packaging structure 1000 and the electronic device A it protects have been subjected to violent transportation.

[0050] Please refer to Figure 2 、 Figure 3 and Figure 4 , Figure 2 yes Figure 1 The structural diagram of the first packaging structure 100 from one perspective is shown. Figure 3 yes Figure 2 The cross-sectional schematic diagram of the first packaging structure 100 is shown. Figure 4 yes Figure 1 The packaging structure 1000 is a schematic structural diagram of the first packaging structure 100 from another perspective. The first packaging structure 100 includes a first main body 110 and a first limiting portion 120.

[0051] The first body 110 includes a first surface 110a and a second surface 110b disposed opposite to each other. The first surface 110a is the surface of the first body 110 facing away from the electronic device A, and the second surface 110b is the surface of the first body 110 facing the electronic device A. Figure 2 As shown, the first surface 110a may be provided with a plurality of decorative grooves 1131. The decorative grooves 1131 may be used to accommodate accessories of the electronic device A. The decorative grooves 1131 may also enhance the strength of the first packaging structure 100 and save material of the first packaging structure 100, thereby saving costs.

[0052] It should be noted that the decorative groove 1131 is not limited to Figure 2 As shown, according to actual needs, the number of decorative grooves 1131 can be more than Figure 2 Quantity or less than Figure 2 The decorative groove 1131 may also be provided at other locations on the first surface 110a or the second surface 110b.

[0053] Please refer to Figure 3 and Figure 4The first stopper 120 is connected to the second surface 110b of the first body 110 and is disposed around the periphery of the first body 110. The first stopper 120 extends from the second surface 110b of the first body 110 in the negative direction of the Z axis. In other words, the first stopper 120 is disposed protruding relative to the second surface 110b of the first body 110.

[0054] It is understood that after the packaging structure 1000 is assembled with the electronic device A, the first limiting portion 120 is used to limit the movement of the electronic device A in the X and Y directions, and provides protection and cushioning for the electronic device A during movement in the X and Y directions. The first body 110 is used to provide protection and cushioning for the electronic device A during movement in the Z direction.

[0055] In the embodiment of the present application, the outer circumference of the first position-limiting portion 120 can be flush with the outer circumference of the first body 110. The outer circumference of the first position-limiting portion 120 and the outer circumference of the first body 110 together constitute the outer circumference 103 of the first packaging structure 100. Specifically, the outer circumference 103 of the first packaging structure 100 includes a first side surface 1031 and a second side surface 1032 disposed opposite each other along the X-direction, and a third side surface 1033 and a fourth side surface 1034 disposed opposite each other along the Y-direction. The first side surface 1031, the third side surface 1033, the second side surface 1032, and the fourth side surface 1034 are sequentially connected to form the outer circumference 103 of the first packaging structure 100.

[0056] See also Figure 5 , Figure 5 yes Figure 1 The schematic diagram of the first packaging structure 1000 from another perspective is shown. The inner circumference of the first stopper 120 intersects with the second surface 110b of the first body 110 to form a boundary line 104. This boundary line 104 can be composed of four sections: a first boundary line 1041 and a second boundary line 1042, sequentially arranged along the X-direction; and a third boundary line 1043 and a fourth boundary line 1044, sequentially arranged along the Y-direction.

[0057] Please refer to Figure 4 and Figure 5The first packaging structure 100 further includes a plurality of notches 111, which are spaced apart along the outer circumferential surface 103 of the first packaging structure 100. Each notch 111 is recessed from the outer circumferential surface 103 of the first packaging structure 100 toward the center of the first packaging structure 100. The notch 111 is the groove-shaped trough body described above. Specifically, the first packaging structure 100 may include a first notch 1111, a second notch 1112, and a plurality of third notches 1113. The first notch 1111 extends from the third side surface 1033 of the first packaging structure 100 along the Y direction to the third intersection line 1043. The second notch 1112 is disposed opposite the first notch 1111 along the Y direction, and extends from the fourth side surface 1034 of the first packaging structure 100 along the Y direction to the fourth intersection line 1044. Exemplarily, both the first notch 1111 and the second notch 1112 are rectangular notches.

[0058] There may be four third notches 1113. Two third notches 1113 may be located on the same side as the first notch 1111, with the two third notches 1113 located at either end of the first notch 1111. The two third notches 1113 located on the same side as the first notch 1111 may each extend from the third side 1033 of the first packaging structure 100 in the Y direction, with each third notch 1113 extending less than the distance between the third side 1033 and the third boundary 1043. Another two third notches 1113 may be located on the same side as the second notch 1112, with the two third notches 1113 located at either end of the second notch 1112. The two third notches 1113 located on the same side as the second notch 1112 may each extend from the fourth side 1034 of the first packaging structure 100 in the Y direction, with each third notch 1113 extending less than the distance between the fourth side 1034 and the fourth boundary 1044. Exemplarily, the four third notches 1113 are each triangular in shape.

[0059] See also Figure 6 , Figure 6 yes Figure 1 The third notch 1113 includes a first notch surface 1114 and a second notch surface 1115. The first notch surface 1114 and the second notch surface 1115 are connected at an angle. For example, the third notch 1113 may be recessed toward the center of the first packaging structure 100 from the first side surface 1031 and / or the second side surface 1032. The present application does not specifically limit the location of the third notch 1113.

[0060] The first body 110 also includes a plurality of through grooves 112, which extend along the Z direction and penetrate the first body 110. The through grooves 112 are also the groove bodies that penetrate the packaging structure 1000 as described above. It can be understood that the through grooves 112 can provide a storage location for other accessories of the electronic device A, such as the slides, power cords or instructions required for the installation or use of the electronic device A. The surface grooves 113 can also provide a storage space to accommodate auxiliary materials of the electronic device A. At the same time, the through grooves 112 can also provide redundant space for the packaging structure 1000. When the packaging structure 1000 is subjected to a certain degree of external force, the packaging structure 1000 can undergo a certain degree of elastic deformation to reduce the impact of the external force on the electronic device A.

[0061] Please refer to Figure 5 and Figure 6 There may be two through-grooves 112, namely a first through-grooves 1121 and a second through-grooves 1122. The first through-grooves 1121 and the second through-grooves 1122 are located in the middle of the first body 110. The length of the first through-grooves 1121 may be the same as the length of the first body 110. The first through-grooves 1121 are rectangular and extend through the first packaging structure 100 in the Z direction. The first through-grooves 1121 include a first groove surface 1123 and a second groove surface 1124 that are oppositely disposed along the X direction, and a third groove surface 1125 and a fourth groove surface 1126 that are oppositely disposed along the Y direction. The first groove surface 1123, the third groove surface 1125, the second groove surface 1124, and the fourth groove surface 1126 are sequentially connected to form the sidewalls of the first through-grooves 1121. The second through-grooves 1122 are spaced apart from the first through-grooves 1121 in the Y direction. The second through-grooves 1122 are rectangular and extend through the first packaging structure 100 in the Z direction. Second through-groove 1122 includes a fifth groove surface 1127 and a sixth groove surface 1128 disposed opposite each other along the X direction, and a seventh groove surface 1129 and an eighth groove surface 1120 disposed opposite each other along the Y direction. Fifth groove surface 1127, seventh groove surface 1129, sixth groove surface 1128, and eighth groove surface 1120 are sequentially connected to form the groove wall of second through-groove 1122.

[0062] In the embodiment of the present application, the first through-groove 1121, the second through-groove 1122, and the third notch 1113 are all grooves of the first packaging structure 100, and multiple first detection grooves 114 can be arranged at the edges of the first through-groove 1121, the second through-groove 1122, and the third notch 1113. The multiple first detection grooves 114 extend from the opening of the through-groove 112 in a direction away from the opening of the through-groove 112. The multiple first detection grooves 114 penetrate the first packaging structure 100 along the Z direction, and the multiple first detection grooves 114 are arranged at intervals. The multiple first detection grooves 114 can be of different sizes and shapes.

[0063] See also Figure 7 , Figure 7 yes Figure 6 The structural diagram of the detection groove 1001 is shown. The size of the detection groove 1001 can satisfy L=C*D / 2, where L is the length of the detection groove 1001, which is the distance from the groove body (through the groove and / or the notch) to the direction away from the groove body, C is the stress concentration factor, C=A / B, A is the tensile strength A of the packaging structure 1000, B is the strain value at the stress risk position when the packaging structure 1000 is subjected to external force, and D is the width of the detection groove 1001.

[0064] The following describes the possibility of arranging the positions of the plurality of first detection slots 114 through a plurality of embodiments.

[0065] For the first possible implementation, please refer to Figure 6 There can be multiple first detection slots 114. The multiple first detection slots 114 are only provided at the periphery of the through slot 112. Each first detection slot 114 extends from the edge of the through slot 112 in a direction away from the through slot 112, and the extension direction can be perpendicular to the edge.

[0066] The plurality of first detection slots 114 extend through the first packaging structure 100 in the Z direction. The length of the first detection slots 114 ranges from 1 mm to 100 mm, which is the distance the first detection slots 114 extend within the plane containing the X and Y directions. The width of the first detection slots 114 ranges from 0.001 mm to 0.1 mm. The width of the first detection slots 114 is perpendicular to the length of the first detection slots 114 within the plane containing the X and Y directions.

[0067] In the embodiment of the present application, the ratio of the length L to the width D of the first detection slot 114 is greater than or equal to 500. The plurality of first detection slots 114 are arranged at intervals, and the intervals between the plurality of first detection slots 114 are greater than or equal to 100 mm.

[0068] Please continue reading Figure 6 The plurality of first detection slots 114 may be a first detection slot 1141 , a second detection slot 1142 , a third detection slot 1143 , a fourth detection slot 1144 and a fifth detection slot 1145 .

[0069] The first detecting groove 1141 extends from the first groove surface 1123 in the opposite direction of the X-direction by a first preset distance, and the first preset distance is also the length of the first detecting groove 1141 .

[0070] The second detecting slot 1142 extends from the second slot surface 1124 along the X direction by a second preset distance, and the second preset distance is also the length of the second detecting slot 1142 .

[0071] The third detection slot 1143 extends from the seventh slot surface 1129 of the second through-slot 1122 in the opposite direction of the Y-direction by a third preset distance. The third preset distance is also the length of the third detection slot 1143. The third detection slot 1143 is provided on the strip structure of the first packaging structure 100 between the first through-slot 1121 and the second through-slot 1122. The third detection slot 1143 may also extend from the fourth slot surface 1126 of the first through-slot 1121 by the third preset distance in the Y-direction. Alternatively, there may be multiple third detection slots 1143, each extending from the fourth slot surface 1126 of the first through-slot 1121 and / or the seventh slot surface 1129 of the second through-slot 1122 by the third preset distance. The extended length of the third detection slot 1143 is less than or equal to half the distance between the first through-slot 1121 and the second through-slot 1122.

[0072] The fourth detecting slot 1144 may extend from the fifth slot surface 1127 of the second through slot 1122 along the opposite direction of the X-direction by a fourth preset distance, which is also the length of the fourth detecting slot 1144 .

[0073] The fifth detecting slot 1145 may extend from the sixth slot surface 1128 of the second through slot 1122 along the X direction by a fifth preset distance, and the fifth preset distance is also the length of the fifth detecting slot 1145 .

[0074] In the second possible implementation, different from the first possible implementation, the first detection slot 114 can also be provided on the periphery of the notch 111. Figure 8 , Figure 8 It is a structural schematic diagram of another first packaging structure 100 provided in an embodiment of the present application. Different from the first possible implementation, the first detection slot body 114 may also include a plurality of sixth detection slots 1146, and the sixth detection slot 1146 may be vertically extended by a sixth preset distance from the first notch surface 1114 of the third notch 1113. The sixth detection slot 1146 runs through the first packaging structure 100 in the Z direction, and the length direction of the sixth detection slot 1146 may be set perpendicular to the first notch surface 1114. Alternatively, the sixth detection slot 1146 may be vertically extended by a sixth preset distance from the second notch surface 1115 of the third notch 1113. Alternatively, the sixth detection slot 1146 may be provided on the first notch surface 1114 and the second notch surface 1115. The present application does not limit the number of the sixth detection slots 1146, as long as the structural strength requirements of the first packaging structure 100 are met.

[0075] In a third possible embodiment, different from the first possible embodiment, the first packaging structure 100 further includes a surface groove 113. Figure 9 , Figure 9Schematic diagram of another first packaging structure 100 provided in an embodiment of the present application. A surface groove 113 is provided at the edge of the through-groove 112 and communicates with the through-groove 112. A first detection groove 114 can also be provided on the groove wall of the surface groove 113 and the periphery of the notch 111 at the edge of the through-groove 112. Specifically, there are two surface grooves 113: a first surface groove 1132 and a second surface groove 1133. The first surface groove 1132 and the second surface groove 1133 can be provided at the edge of the first through-groove 112 and communicate with the first through-groove 112. The first surface groove 1132 is recessed from the first groove surface 1123 in the direction opposite to the X-direction and extends through the first surface 110a. The depth of the first surface groove 1132 in the Z-direction is less than the thickness of the first body 110. The second surface groove 1133 is recessed from the second groove surface 1124 in the X-direction and extends through the first surface 110a. The depth of the second surface groove 1133 in the Z-direction is less than the thickness of the first body 110. The first surface groove 1132 and the second surface groove 1133 are both connected to the second through groove 1122 .

[0076] In this embodiment, the first inspection groove 1141 can extend from the first groove surface 1123 of the first through-groove 112, and the first inspection groove 1141 can penetrate the groove wall of the first surface groove 1132 along the Z direction. The second inspection groove 1142 can extend from the second groove surface 1124 of the first through-groove 112, and the second inspection groove 1142 can penetrate the groove wall of the second surface groove 1133 along the Z direction.

[0077] It is understandable that extending the detection groove 1001 from the groove wall of the surface groove can reduce its thickness, so that the detection groove 1001 can crack when subjected to a relatively small external force (exceeding a safety value).

[0078] Please refer to Figure 10 and Figure 11 , Figure 10 yes Figure 1 The schematic structural diagram of the second packaging structure 200 of the packaging structure 1000 is shown from one perspective. Figure 11 yes Figure 10 FIG2 is a cross-sectional view of a second packaging structure 200 , which includes a second position-limiting portion 210 and a second body 220 .

[0079] The second body 220 includes a third surface 220a and a fourth surface 220b that are opposite to each other along the Z direction. The third surface 220a is the surface of the second body 220 facing the electronic device A, and the fourth surface 220b is the surface of the second body 220 facing away from the electronic device A.

[0080] The second stopper 210 is connected to the third surface 220a of the second body 220 and is disposed around the periphery of the second body 220. The second stopper 210 extends in the Z-axis direction relative to the third surface 220a of the second body 220. In other words, the second stopper 210 is disposed protruding relative to the third surface 220a of the second body 220.

[0081] It is understood that after the packaging structure 1000 is assembled with the electronic device A, the second limiting portion 210 is used to limit the movement of the electronic device A in the X and Y directions, and provides protection and cushioning for the electronic device A during movement in the X and Y directions. The second body 220 is used to provide protection and cushioning for the electronic device A during movement in the Z direction.

[0082] In the embodiment of the present application, the outer circumference of the second position-limiting portion 210 can be flush with the outer circumference of the second body 220. The outer circumference of the second position-limiting portion 210 and the outer circumference of the second body 220 together constitute the outer circumference 203 of the second packaging structure 200. Specifically, the outer circumference of the second packaging structure 200 includes a fifth side surface 2031 and a sixth side surface 2032 disposed opposite each other along the X-direction, and a seventh side surface 2033 and an eighth side surface 2034 disposed opposite each other along the Y-direction. The fifth side surface 2031, the seventh side surface 2033, the sixth side surface 2032, and the eighth side surface 2034 are sequentially connected to form the outer circumference 203 of the second packaging structure 200.

[0083] See also Figure 12 , Figure 12 yes Figure 10 The second packaging structure 200 is shown in another perspective. The inner circumference of the second stopper 210 intersects the third surface 220a of the second body 220 to form a boundary line 204. This boundary line 204 can be composed of four line segments: a fifth boundary line 2041 and a sixth boundary line 2042, sequentially arranged along the X-direction, and a seventh boundary line 2043 and an eighth boundary line 2044, sequentially arranged along the Y-direction.

[0084] The second packaging structure 200 also includes a plurality of notches 223. The plurality of notches 223 are arranged along the outer circumferential surface 203 of the second packaging structure 200, with each notch 223 being recessed from the outer circumferential surface 203 of the second packaging structure 200 toward the center of the second packaging structure 200. The notches 223 are the groove-shaped grooves described above. Specifically, the second packaging structure 200 may include a fourth notch 2231, a fifth notch 2232, and a plurality of sixth notches 2233. The fourth notch 2231 extends from the seventh side 2033 of the second packaging structure 200 in the Y direction, and the extension distance may be greater than the distance between the seventh side 2033 and the seventh boundary line 2043. The fourth notch 2231 is a rectangular notch 223. The fourth notch 2231 includes a third notch surface 2234 and a fourth notch surface 2235 arranged opposite each other in the X direction. Both the third notch surface 2234 and the fourth notch surface 2235 may be perpendicular to the seventh side 2033 of the second packaging structure 200 (within a tolerance range).

[0085] The fifth notch 2232 can be positioned opposite the fourth notch 2231 in the Y direction. The fifth notch 2232 extends from the eighth side surface 2034 of the second packaging structure 200 in the opposite direction of the Y direction. The extension distance of the fifth notch 2232 is greater than the distance between the eighth side surface 2034 and the eighth boundary line 2044. The fifth notch 2232 is a rectangular notch 223. The fifth notch 2232 includes fifth notch 223 surfaces 2236 and 2237 arranged sequentially along the X direction. The fifth notch 223 surfaces 2236 and 2237 can be perpendicular to the eighth side surface 2034 of the second packaging structure 200 (within a tolerance range).

[0086] There can be four sixth notches 2233, two sixth notches 2233 can be set on the same side as the fourth notch 2231, and the two sixth notches 2233 are respectively located at both ends of the fourth notch 2231. The two sixth notches 2233 set on the same side as the fourth notch 2231 can both extend from the seventh side 2033 of the second packaging structure 200 along the Y direction, and the extension length of each sixth notch 2233 is less than the distance between the seventh side 2033 and the third boundary line 1043.

[0087] The other two sixth notches 2233 can be provided on the same side as the fifth notch 2232, and the two sixth notches 2233 are located at either end of the fifth notch 2232. The two sixth notches 2233 provided on the same side as the sixth notch 2233 can both extend from the eighth side surface 2034 of the second packaging structure 200 in the opposite direction of the Y-direction. The extension length of each sixth notch 2233 can be less than the distance between the eighth side surface 2034 and the eighth boundary line 2044. For example, the four sixth notches 2233 can all be similar to the triangular notches 223.

[0088] The sixth notch 2233 includes a seventh notch surface 2238 and an eighth notch surface 2239. The seventh notch surface 2238 and the eighth notch surface 2239 are connected at an angle. For example, the sixth notch 2233 can be recessed from the fifth side surface 2031 and / or the sixth side surface 2032 toward the center of the second packaging structure 200. After the first packaging structure 100 and the second packaging structure 200 are connected to opposite sides of the electronic device A, the sixth notch 2233 and the third notch 1113 can be positioned opposite each other in the Z direction.

[0089] Please refer to Figure 10 , the second body 220 is provided with a mesh structure 221. Specifically, the mesh structure 221 can be provided in the middle part of the second body 220. The mesh structure 221 includes a plurality of meshes 2211 and a plurality of edges 2212, and the plurality of meshes 2211 are arranged in an array in the plane where the X direction and the Y direction are located. Among them, the mesh is also the groove-shaped trough body mentioned above. The mesh 2211 is a blind hole, extending from the third surface 220a to the fourth surface 220b, and the depth of the blind hole is less than the thickness of the second body 220. Between two adjacent meshes 2211 is the edge 2212 of the mesh structure 221. The width of the edge 2212 is also the distance between the openings of the two adjacent meshes 2211 on the third surface 220a. The length direction of the edge 2212 is also the direction perpendicular to the width direction of the edge 2212 in the plane where the X direction and the Y direction are located. The shape of each mesh 2211 is the same. Exemplarily, the middle portion of the mesh structure 221 may be a solid structure 2213 without mesh holes 2211 .

[0090] It is understood that the mesh structure 221 has good deformation ability and can effectively attenuate external forces thereon, thereby protecting the electronic device A. The solid structure 2213 of the mesh structure 221 can enhance the structural strength of the mesh structure 221 , so that the structural strength of the second packaging structure 200 meets packaging requirements.

[0091] In the embodiment of the present application, the notch 223 and the mesh 2211 of the mesh structure 221 are all troughs of the second packaging structure 200, and multiple second detection troughs 225 can be arranged at the periphery of the notch 223 or the mesh 2211 and the periphery of the mesh 2211 of the mesh structure 221. The multiple second detection troughs 225 can extend from the edge of the notch 223 to a direction perpendicular to the edge of the notch 223 or the mesh 2211 by a second preset distance. The second preset distance is the length of the second detection trough 225. The multiple second detection troughs 225 penetrate the second packaging structure 200 along the Z direction, and the multiple second detection troughs 225 are arranged at intervals. The sizes and shapes of the multiple second detection troughs 225 can be different.

[0092] The size of the second detection tank 225 is set in the same manner as the size of the first detection tank 114 , and will not be described in detail here.

[0093] The following describes the possibility of arranging the positions of the plurality of second detection slots 225 through a plurality of embodiments.

[0094] For the first possible implementation, see Figure 12 There can be multiple second detection slots 225, each extending from the edges of the rectangular notches (the fourth notch 2231 and the fifth notch 2232) and the edges of the mesh 2211 of the mesh structure 221. The second detection slots 225 can extend perpendicular to the edges, or they can extend at an acute angle to the edges.

[0095] Multiple second detection slots 225 extend through the second packaging structure 200 in the Z direction. The length of each second detection slot 225 ranges from 1 mm to 100 mm, which is the distance the second detection slot 225 extends within the plane containing the X and Y directions. The width of each second detection slot 225 ranges from 0.001 mm to 0.1 mm. The width of each second detection slot 225 is perpendicular to the length of the second detection slot 225 within the plane containing the X and Y directions.

[0096] In the embodiment of the present application, the ratio of the length to the width of the second detection slot 225 may be greater than or equal to 500. The plurality of second detection slots 225 are arranged at intervals.

[0097] Please continue reading Figure 12 The plurality of second detection slots 225 are respectively two seventh detection slots 2251, two eighth detection slots 2252, and a plurality of ninth detection slots 2253. The two seventh detection slots are respectively a first sub-slot 2511 and a second sub-slot 2512. The first sub-slot 2511 can extend a certain length from the third notch surface 2234 of the fourth notch 2231 in the direction opposite to the X-direction. The second sub-slot 2512 can extend a certain length from the fourth notch surface 2235 of the fourth notch 2231 in the X-direction. The lengths of the first sub-slot 2511 and the second sub-slot 2512 can be the same or different.

[0098] The two eighth detection slots 2252 can be a third sub-slot 2521 and a fourth sub-slot 2522, respectively. The third sub-slot 2521 can extend a certain length from the fifth notch surface 2236 of the fifth notch 2232 in the opposite direction of the X-direction. The fourth sub-slot 2522 can extend a certain length from the sixth notch surface 2237 of the fifth notch 2232 in the opposite direction of the X-direction. The lengths of the third sub-slot 2521 and the fourth sub-slot 2522 can be the same or different.

[0099] Multiple ninth detection slots 2253 can extend from the edge of the mesh 2211 to the adjacent mesh 2211, that is, multiple ninth detection slots 2253 can be provided at the edge 2212 of the mesh structure 221. The ninth detection slot 2253 can extend from the opening of one mesh 2211 on the third surface 220a to the opening of another adjacent mesh 2211 on the third surface 220a. The extension distance of the ninth detection slot 2253 is less than half the width of the edge 2212. It should be noted that there can also be one ninth detection slot 2253, and this application does not limit the number of ninth detection slots 2253.

[0100] It can be understood that during the transportation of electronic device A, if it falls due to human factors, cracks will be generated in the second detection groove 225, and the cracks can extend to penetrate the entire structure of the second packaging structure 200, causing cracks in local areas of the second packaging structure 200. Therefore, violent transportation behaviors during transportation can be effectively recorded, and violent damage during transportation can be accurately identified before the electronic device is installed.

[0101] In the second possible implementation, different from the first possible implementation, the second detection slot 225 can also be provided at the periphery of the sixth notch. Figure 13 , Figure 13 yes Figure 10 A schematic structural diagram of another second packaging structure 200 is shown. The second detection slot body 225 may further include a plurality of tenth detection slots 2254, and the tenth detection slot 2254 may extend vertically by a seventh preset distance from the seventh notch surface 2238 of the sixth notch 2233. The seventh preset distance is also the length of the tenth detection slot 2254. The tenth detection slot 2254 runs through the second packaging structure 200 in the Z direction, and the length direction of the tenth detection slot 2254 may be set perpendicular to the seventh notch surface 2238. Alternatively, the tenth detection slot 2254 may extend vertically by a seventh preset distance from the eighth notch surface 2239 of the sixth notch 2233. Alternatively, the tenth detection slot 2254 may be provided on the seventh notch surface 2238 and the eighth notch surface 2239. This application does not impose any restrictions on the number of the tenth detection slots 2254, as long as the structural strength requirements of the second packaging structure 200 are met.

[0102] Please refer to Figure 14 and Figure 15 , Figure 14 It is a structural schematic diagram of the relative positions of the detection slot 101 and a marking line 300 provided in an embodiment of the present application. Figure 15: This is a structural diagram of the relative positions of the detection slot 101 and another marking line 300 provided in an embodiment of the present application. The packaging structure 1000 also includes a plurality of marking lines 300. The marking lines 300 are provided on the first packaging structure 100 and / or the second packaging structure 200. A marking line 300 is spaced apart from a detection slot 1001 (a first detection slot body 114 or a second detection slot body 225). The marking line 300 can be provided on the outside of the detection slot 1001. Specifically, the marking line 300 can be provided on one side of the extension direction of a detection slot 1001, and the marking line 300 is spaced apart from the detection slot 1001 by a preset identification distance. The preset identification distance is half the length of the detection slot (allowable tolerance range). The marking line 300 is used to determine whether the external force applied to the packaging structure 1000 exceeds the external force threshold, thereby determining whether the packaging structure 1000 and the electronic device A it protects have been subjected to violent transportation. Among them, the external force threshold can be the maximum value of the external force that the electronic device A can safely withstand.

[0103] It should be noted that the shapes and extension lengths of the multiple detection slots 1001 of the present application may be the same or different. The specific shape and length of the detection slot 1001 can be specifically designed according to its position on the packaging structure 1000. Specifically, the multiple marking lines 300 can be respectively arranged on one side of the multiple first detection slot bodies 114 at the periphery of the through slot 112 (the first through slot 1121 and the second through slot 1122). There can also be multiple marking lines 300 respectively arranged on one side of the multiple detection slots 1001 (the first detection slot body 114 or the second detection slot body 225) at the periphery of the notch (the notch 111 of the first packaging structure 100 or the notch 223 of the second packaging structure 200). The marking line 300 can also be arranged on one side of the detection slot 1001 at the edge 2212 in the mesh structure 221.

[0104] A marking line 300 is spaced apart from a detection slot 1001 . The detection slot 1001 is used to generate a crack 1 . The marking line 300 is used to determine the transportation status of the packaging structure 1000 based on the relative position relationship between the marking line 300 and the crack 1 .

[0105] The packaging structure 1000 includes a normal transportation state and a violent transportation state. When the packaging structure 1000 is in the normal transportation state, the crack 1 and the marking line 300 are spaced apart. When the packaging structure 1000 is in the violent transportation state, the crack 1 and the marking line 300 intersect.

[0106] For example, the detection slot 1001 provided at the edge 2212 of the mesh structure 221 may not be provided with the marking line 300. Since the width of the edge 2212 is relatively narrow, if the packaging structure 1000 is subjected to violent transportation, cracks may form in the detection slot 1001 (second detection slot body 225) at the edge 2212, potentially penetrating the width of the edge 2212. Therefore, when the edge 2212 breaks, it can be considered that the packaging structure 1000 has been subjected to violent transportation.

[0107] It is understood that detection slots 1001 are provided at stress risk locations around the rim of the container. When packaging structure 1000 is subjected to external forces exceeding a certain magnitude, the force can cause cracks 1 to form around detection slots 1001. Cracks 1 extend from detection slots 1001 to the surrounding area. When cracks 1 extend to or beyond marking line 300, it can be determined that electronic device A has been subjected to violent transportation during transportation.

[0108] For example, the marking line 300 can be a straight line, an arc line, or a broken line. A straight marking line 300 can be located on the side of the detection slot 1001 away from the slot body, and the extending direction of the marking line 300 can be the same as the width direction of the detection slot 1001. The center of curvature of the arc-shaped marking line 300 can be the midpoint of the end of the detection slot 1001. A broken line marking line 300 can be located on the periphery of the rectangular detection slot 1001.

[0109] See also Figure 16 , Figure 16 This is a flow chart of a method for designing the position of a detection slot 1001 provided in an embodiment of the present application. Figures 1-15 Remember the above description, regarding the improvements to the detection slot 1001, all can be applied to the above description of the detection slot 1001 without conflict. The design method for the position of the detection slot 1001 provided in this application includes the following steps.

[0110] S100 : Determine stress risk locations on the packaging structure 1000 .

[0111] S200: forming a detection groove 1001 at a stress risk position.

[0112] S100, S200 and S300 will be described in detail below.

[0113] S100 : Determine stress risk locations on the packaging structure 1000 .

[0114] Specifically, simulation or actual measurement is used to determine which drop risk of the packaging structure 1000 is greatest. For example, after the packaging structure 1000 falls, the edge 2212 of the packaging structure 1000 contacts the ground, or the top corner of the packaging structure 1000 contacts the ground, or a surface of the packaging structure 1000 directly contacts the ground. The stress risk location on the packaging structure 1000 is then determined based on the drop simulation or actual measurement results. The strain value of the determined stress risk location is greater than a preset strain threshold. The preset strain threshold range is between 4000ε and 5000ε.

[0115] S200: forming a detection groove 1001 at a stress risk position.

[0116] The detection slots 1001 are arranged along the edge structure of the packaging structure 1000, and the detection slots 1001 penetrate the packaging structure 1000 in the thickness direction of the packaging structure 1000. The plurality of detection slots 1001 are arranged at intervals.

[0117] See also Figure 17 , Figure 17 1001. The embodiment of the present application provides a flow chart of a method for designing the size of a detection slot 1001. Step S200 may include the following steps:

[0118] S210 : Determine the tensile strength A of the packaging structure 1000 .

[0119] Specifically, the tensile strength A is determined based on the material of the packaging structure 1000 by searching material parameters or performing actual measurements.

[0120] S220 : Determine the strain value B of the stress risk position on the packaging structure 1000 .

[0121] Specifically, the strain value B at the stress risk position on the packaging structure is determined through drop simulation or actual measurement of the packaging structure 1000 .

[0122] S230: Calculate the stress concentration factor required for crack 1 to occur using the formula C=A / B.

[0123] S240: Determine the width D of the processed detection groove 1001.

[0124] S250: Calculate and obtain the length L of the detection slot 1001 = C*D / 2.

[0125] See also Figure 18 , Figure 18 1001. This is a flow chart of another method for designing the position of a detection slot 1001 provided in an embodiment of the present application. In the method for designing the position of another detection slot 1001 provided in an embodiment of the present application, in addition to the above steps S100 and S200, step S300 may also be included.

[0126] S300: A marking line 300 is formed on the side of the detection slot 1001 away from the slot body and spaced apart from the detection slot 1001, wherein the distance from the marking line 300 to the detection slot 1001 is half the length of the detection slot 1001, and the length of the detection slot 1001 is the distance it extends from the slot body toward away from the slot body.

The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for those skilled in the art, according to the idea of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
