Description
Technical Field
[0001] This application belongs to the field of logistics and transportation technology, specifically relating to a clamping protective structure, a packaging cover, a packaging component, and an electrical component. Background Technology
[0002] Ovens, refrigerators, dishwashers and other electrical appliances are subjected to impacts, vibrations and other loads during handling and transportation. Their packaging must protect the electrical appliances from damage to their appearance and function.
[0003] Among the related technologies, the packaging test for electrical equipment is the clamping test, which is the most demanding, requiring that the components of the electrical equipment be undamaged and that the surface of the equipment be free from deformation.
[0004] In related technologies, wooden strips are often used for the packaging of electrical equipment to achieve clamping protection. However, the bending stiffness of wooden strips may be insufficient. In addition to axial compression deformation, the wooden strips may also bend, causing the clamping machine to contact the two sides of the electrical equipment, resulting in plastic deformation of the electrical equipment and failing to meet the shipping requirements. Summary of the Invention
[0005] To address the aforementioned technical problems, this application provides a clamping and protective structure, a packaging cover, a packaging assembly, and an electrical assembly to improve the clamping and protective effect of electrical equipment packaging.
[0006] The technical solution of this application is as follows:
[0007] In a first aspect, this application provides a clamping protective structure, the clamping protective structure comprising:
[0008] There are two limit components, arranged in a relatively opposite manner;
[0009] The bending member is connected to the two limiting members at both ends. The bending member has a first side and a second side. The first side of the bending member is provided with a recessed portion extending to the second side. The middle part of the second side of the bending member is provided with a protrusion, so as to reduce the thickness of the bending member while maintaining compressive strength.
[0010] When the clamping protective structure provided in this application is used for packaging protection of electrical equipment, the two limiting members of the clamping protective structure are respectively disposed on both sides of the protective part of the electrical equipment, and the two ends of the anti-bending member are respectively connected to the two limiting members to achieve packaging protection of the electrical equipment. Since the first side of the anti-bending member is provided with a recessed portion extending to the second side, and the middle of the second side of the anti-bending member is provided with a protrusion, in actual protection, the recessed portion of the anti-bending member is located on the side of the protective part facing away from the electrical equipment, and the protrusion of the anti-bending member faces the protective part. The anti-bending member with the recessed portion can make the function... Force is concentrated at the recessed part, and while fully utilizing its compressive strength, the thickness of the bending member is reduced, thereby achieving the effect of resisting the same clamping load with the minimum thickness of the bending member. In addition, the protrusion provided on the second side of the bending member can constrain the middle of the bending member, reduce the bending deformation span of the bending member, and increase the bending stiffness and stability of the bending member, so as to have a better buckling protection effect, so as to ensure that the components of the electrical equipment are undamaged and the appearance surface is undeformed as much as possible, thereby preventing plastic deformation of the electrical equipment and improving the equipment protection effect.
[0011] In some embodiments, the protrusion and the recess are positioned opposite each other at their centers. Since the center of the recess in the protective member is the main stress-bearing area, the protrusion positioned there can significantly increase the bending stiffness and stability of the bending member.
[0012] In some implementations, the protrusions are provided one or multiple protrusions spaced apart.
[0013] In some implementations, the recess is curved or catenary-shaped.
[0014] In some embodiments, when the shape of the recess is a catenary shape, the vertical distance between the lowest point of the catenary shape and the endpoint of the catenary shape is a, and the sum of the thicknesses of the bending member and the protrusion is t, where a ≤ t / 10.
[0015] In some implementations, the end of the bending member and the limiting member are mortised and tenoned together.
[0016] In some implementations, two or more bending members are spaced apart to further improve the clamping and protective effect of the packaging of electrical equipment.
[0017] Secondly, this application also provides a packaging cover, characterized in that the packaging cover comprises:
[0018] Protective components used to cover the ends of electrical equipment;
[0019] In the above-mentioned clamping protective structure, the two limiting members are respectively disposed on both sides of the protective member, the recessed part of the anti-bending member is located on the side of the protective member facing away from the electrical equipment, and the protruding part of the anti-bending member faces the protective member.
[0020] Packaging cover plates with the aforementioned clamping protective structure can reduce the thickness of the bending member while fully utilizing its compressive strength, thereby achieving the effect of resisting the same clamping load with the thinnest bending member. In addition, the protrusion on the second side of the bending member can constrain the middle of the bending member, reduce the bending deformation span of the bending member, increase the bending stiffness and stability of the bending member, and thus have a better buckling protection effect. This ensures that the components of the electrical equipment are undamaged and the surface of the equipment is free from deformation, preventing plastic deformation of the electrical equipment and improving the equipment protection effect.
[0021] In some implementations, the protective component has a positioning groove corresponding to the anti-bending component on the side facing the clamping protective structure, and the bottom of the positioning groove has a snap-fit part corresponding to the protrusion. The anti-bending component is embedded in the positioning groove, and the protrusion is embedded in the corresponding snap-fit part to realize the assembly of the anti-bending component on the protective component.
[0022] In some implementations, the limiting member overlaps the side of the protective member.
[0023] In some embodiments, the packaging cover further includes:
[0024] A support member is laid on the outer surface of the protective member and is positioned between the two limiting members of the clamping protective structure to protect the protective member and thereby improve the protective effect on electrical equipment.
[0025] Thirdly, this application also provides a packaging assembly, which includes the aforementioned clamping and protective structure.
[0026] Packaging components with the aforementioned clamping protection structure can reduce the thickness of the bending member while fully utilizing its compressive strength, thereby achieving the effect of resisting the same clamping load with the thinnest bending member. Furthermore, the protrusion on the second side of the bending member can constrain the center of the bending member, reducing the bending deformation span and increasing its bending stiffness and stability. This results in superior buckling protection, ensuring that electrical equipment components remain undamaged and their surfaces are free from deformation, preventing plastic deformation and improving overall equipment protection.
[0027] Fourthly, this application also provides an electrical component, which includes an electrical appliance and the aforementioned packaging component, wherein the electrical appliance is enclosed within the packaging component.
[0028] Electrical components with the aforementioned packaging elements can reduce the thickness of the bending members while fully utilizing the compressive strength of the clamping protective structure, thereby achieving the effect of resisting the same clamping load with the thinnest bending member. In addition, the protrusion provided on the second side of the bending member can constrain the middle of the bending member, reduce the bending deformation span of the bending member, increase the bending stiffness and stability of the bending member, and thus have a better buckling protection effect. This ensures that the electrical equipment components are undamaged and the appearance surface is free from deformation, thereby preventing plastic deformation of the electrical equipment and improving the equipment protection effect.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0047] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0048] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0049] This application is described below with reference to the accompanying drawings and specific embodiments:
[0050] Ovens, refrigerators, dishwashers, and other electrical appliances are subjected to impacts and vibrations during handling and transportation. Their packaging must protect them from visual and functional damage. Among the related technologies, the clamping test is the most demanding in packaging testing for electrical appliances, requiring that the components of the appliance remain undamaged and that its surface remain free of deformation.
[0051] The embodiments of this application will now be described in detail using a dishwasher as an example.
[0052] The dishwasher packaging test is most stringent in the clamping test, with a clamping force of up to 10,000 N, repeated 12 times, and the area of action dynamically changing. The test uses two parallel clamps to clamp the left and right sides of the dishwasher, and successively conducts 3 full clamps, 3 full clamps after a horizontal rotation of 180°, 3 half clamps with a side deviation of 15cm×15cm, and 3 half clamps after a horizontal rotation of 180°. The half clamps only clamp the front and rear sides, and each clamp is applied with a clamping force of 10,000±50N for 30 seconds.
[0053] The acceptance criteria for dishwashers are stringent, requiring that all components and exterior surfaces be free from damage and deformation. Because the sheet metal on both sides of the dishwasher is secured by screws around the perimeter, and there is no central stiffener or support, a semi-clamping test was conducted with a relatively weak anti-clamping device. This resulted in a noticeable bulge forming on the top of the corrugated cardboard box containing the packaging components, and severe deformation of the sheet metal on both sides, exceeding the acceptance standards.
[0054] In related technologies, dishwasher packaging often uses wooden strips for clamping and protection. The bending deformation of the wooden strips in a stable buckling state increases the rigidity of the dishwasher's clamping operation, preventing the clamping machine from directly contacting the sheet metal on both sides. If the bending stiffness of the wooden strips is insufficient, in addition to axial compression deformation, the strips will also bend, causing the clamping machine to contact the sheet metal on both sides, resulting in plastic deformation of the sheet metal and failing to meet shipping requirements.
[0055] Based on the above-mentioned technical problems, embodiments of this application provide a clamping protection structure, a packaging cover, a packaging component, and an electrical component to improve the clamping protection effect of electrical equipment packaging.
[0056] Figure 1 This is a schematic diagram of a clamping protective structure 100 provided in an embodiment of this application, combined with... Figure 1 The clamping protective structure 100 includes a limiting member 101 and an anti-bending member 102. There are two limiting members 101 arranged opposite each other. The two ends of the anti-bending member 102 are respectively connected to the two limiting members 101. The anti-bending member 102 has a first side and a second side opposite each other. The first side of the anti-bending member 102 is provided with a recessed portion 103 extending to the second side, and the middle of the second side of the anti-bending member 102 is provided with a protrusion 104.
[0057] Figure 2 For having Figure 1 The schematic diagram of the packaging cover of the clamping protective structure 100 shown is combined with... Figure 1 as well as Figure 2 When the provided clamping protective structure 100 is used for packaging protection of electrical equipment 500, the two limiting members 101 of the clamping protective structure 100 are respectively disposed on both sides of the protective member 200 of the electrical equipment 500, and the two ends of the anti-bending member 102 are respectively connected to the two limiting members 101 to achieve packaging protection of the electrical equipment 500. Since the first side of the anti-bending member 102 is provided with a recessed portion 103 extending to the second side, and the middle of the second side of the anti-bending member 102 is provided with a protrusion 104, in actual protection, the recessed portion 103 of the anti-bending member 102 is located on the side of the protective member 200 facing away from the electrical equipment 500, and the protrusion 104 of the anti-bending member 102 faces the protective member 200, thus having The bending member 102 of the recessed portion 103 can concentrate the force at the recessed portion, and reduce the thickness of the bending member 102 while giving full play to its compressive strength, thereby achieving the effect of resisting the same clamping load with the minimum thickness of the bending member 102. In addition, the protrusion 104 provided on the second side of the bending member 102 can constrain the middle of the bending member 102, reduce the bending deformation span of the bending member 102, and increase the bending stiffness and stability of the bending member 102, so as to have a better buckling protection effect, and to ensure that the components of the electrical equipment 500 are undamaged and the appearance surface is undeformed as much as possible, so as to prevent the electrical equipment 500 from undergoing plastic deformation and improve the equipment protection effect of the electrical equipment 500.
[0058] Figure 3 for Figure 1 An explosion diagram. Figure 4 for Figure 1 A structural diagram of the limiting component. (Combined with...) Figures 1-4 The two limiting members 101 of the clamping protective structure 100 can be set in parallel. Both limiting members 101 can be wooden strips and can be square. When the clamping protective structure 100 is assembled on the packaging cover, the two limiting members 101 can be assembled on both sides of the protective member 200 by overlapping.
[0059] Of course, in other embodiments, the two limiting members 101 of the clamping protective structure 100 may also have a certain included angle. The specific adjustment can be made according to the electrical equipment 500 to be protected, which will not be elaborated here.
[0060] Figure 5 for Figure 1 A structural diagram of the bending-resistant component. (Combined with...) Figures 1-5The bending-resistant member 102 of the clamping protective structure 100 can also be a wooden strip, the end of which can be mortised and tenoned with the limiting member 101. Specifically, the end of the bending-resistant member 102 can be provided with a tenon 105, and the corresponding part of the limiting member 101 is provided with a mortise 106. The tenon 105 at the end of the bending-resistant member 102 can be inserted into the mortise 106 of the corresponding limiting member 101, so that the bending-resistant member 102 and the limiting member 101 can be assembled, so that the clamping protective structure 100 forms a whole.
[0061] Combination Figures 1-3 The clamping protective structure 100 can have two bending members 102, which can be arranged in parallel to further improve the clamping protection effect. Of course, if the bending member 102 has sufficient supporting bending strength, only one bending member 102 can be provided. If the supporting bending strength of the bending member 102 is insufficient, more bending members 102 can be provided. When there are multiple bending members 102, the bending members 102 can be parallel and / or have a certain angle between them, which is not limited here.
[0062] In other embodiments, the limiting member 101 and the bending member 102 constituting the clamping protective structure 100 may also be made of thin metal. When they are made of metal, the limiting member 101 and the bending member 102 may be integrally formed or welded together, etc., which are not limited here.
[0063] Figure 6 for Figure 5 The main view diagram, combined with Figure 5 as well as Figure 6 The protrusion 104 of the bending resist 102 can be square, and it is preferably located at the center of the recess 103. This is because the center of the recess 103 of the protective member 200 is the main stress area, and the protrusion 104 located here can provide greater constraint on the center of the bending resist 102, thereby maximizing the bending stiffness and stability of the bending resist 102. The protrusion 104 can be integrally formed on the second side of the bending resist 102, or it can be detachably assembled onto the bending resist 102 using mortise and tenon joints or other connection methods; no limitation is made here.
[0064] In this embodiment, the protrusion 104 can be provided one or multiple protrusions spaced apart. When there is only one protrusion 104, the protrusion 104 can be disposed opposite to the center of the recess 103. That is, the center of the recess 103 is usually the center of the first side of the bending member 102, while the protrusion 104 is disposed at the center of the second side of the bending member 102, and the two are disposed opposite to each other. When there are multiple protrusions 104, the multiple protrusions 104 can be spaced apart along the length direction of the bending member 102 at the center of the second side of the bending member 102 to counteract the central constraint of the bending member, reduce the bending deformation span of the bending member, and improve the bending stiffness and stability of the bending member 102.
[0065] Combination Figure 6 In this embodiment, the recessed portion 103 can be a catenary shape. Taking the lowest point of the catenary shape as the origin, x as the horizontal direction of the line, and y as the vertical upward direction, the equation of the catenary shape is: Where a is the vertical distance between the lowest point of the catenary and the endpoint of the catenary. If the sum of the thicknesses of the anti-bending member 102 and the protrusion 104 is t, according to simulation analysis, when a is less than or equal to t / 10, compared with the anti-bending strips in the related technology, the anti-bending member 102 with the recess 103 in this application embodiment can reduce the buckling performance without reducing the thickness.
[0066] The number n of the bending members 102 is determined based on the maximum thickness of the packaging cover and cost. Since the two side plates of the clamping machine are not perfectly parallel, using only one bending member 102 may cause the front end of the machine side plate to be clamped, so at least two bending members 102 can be used for protection. Considering the limited packaging height, the thickness of the bending members 102 cannot be too large, so more than two bending members 102 can be used for protection if necessary.
[0067] Based on the determined number of bending-resistant members 102, the thickness of the bending-resistant member 102 is determined as follows: Where F is the clamping force; L is the length of the bending member 102, which is slightly longer than the width of the electrical equipment 500 to be protected; and E is the elastic modulus of the bending member 102.
[0068] Finally, the clamping protective structure 100 with the above parameters determined is assembled onto the protective component 200 of the packaging cover.
[0069] Of course, in other embodiments, the shape of the recess 103 may also be arc-shaped, and this is not a limitation.
[0070] Figure 7 for Figure 2 The explosion diagram, combined with Figure 2 as well as Figure 7Based on the aforementioned clamping protective structure 100, the packaging cover of this application embodiment includes a protective member 200 for covering the end of the electrical device 500 and the aforementioned clamping protective structure 100. The two limiting members 101 of the clamping protective structure 100 are respectively disposed on both sides of the protective member 200, the recessed portion 103 of the anti-bending member 102 is located on the side of the protective member 200 facing away from the electrical device 500, and the protruding portion 104 of the anti-bending member 102 faces the protective member 200.
[0071] The packaging cover with the aforementioned clamping protective structure 100 can reduce the thickness of the bending member 102 while fully utilizing its compressive strength, thereby achieving the effect of resisting the same clamping load with the minimum thickness of the bending member 102. In addition, the protrusion 104 provided on the second side of the bending member 102 can constrain the middle of the bending member 102, reduce the bending deformation span of the bending member 102, increase the bending stiffness and stability of the bending member 102, and have a better buckling protection effect. This ensures that the components of the electrical equipment 500 are undamaged and the surface of the electrical equipment 500 is free from deformation, preventing plastic deformation of the electrical equipment 500 and improving the equipment protection effect of the electrical equipment 500.
[0072] Figure 8 for Figure 2 A structural schematic diagram of the protective component 200. (Combined with...) Figure 8 In this embodiment, the protective member 200 can be foam, and at least two sides of the protective member 200 can be provided with overlapping members 201. The overlapping members 201 can include multiple limiting posts provided at the corners of the protective member 200. The overlapping members 201 are fitted onto the end of the electrical equipment 500 to be protected, so that the protective member 200 can be assembled onto the electrical equipment 500 to be protected. The protective member 200 has a positioning groove 202 corresponding to the anti-bending member 102 on the side facing the clamping protective structure 100. The bottom of the positioning groove 202 is provided with a snap-fit part 203 corresponding to the protrusion 104. The anti-bending member 102 is embedded in the positioning groove 202, and the protrusion 104 is embedded in the corresponding snap-fit part 203 to realize the assembly of the anti-bending member 102 on the protective member 200.
[0073] The snap-fit portion 203 in this embodiment can be a through hole or a groove. The specific configuration can be adjusted according to the thickness of the protective member 200 and the thickness of the protrusion 104, which will not be elaborated here.
[0074] In this embodiment, since the anti-bending member 102 is embedded in the positioning groove 202 and the protrusion 104 is embedded in the corresponding snap-fit part 203, the thickness of the packaging cover plate can be reduced, thereby allowing the electrical equipment 500 to have a larger packing capacity and reduce transportation costs.
[0075] Furthermore, combined Figure 8 The protective component 200 may have an embedding groove 204 on its side. The length of the embedding groove 204 matches the length of the limiting component 101. The limiting component 101 can be embedded into the corresponding embedding groove 204 to enhance the reliability of the connection between the limiting component 101 and the protective component 200.
[0076] Combination Figure 2 as well as Figure 7 The packaging cover of this application embodiment also includes a support member 300, which can be a cardboard box. It is laid on the outer surface of the protective member 200 and is disposed between the two limiting members 101 of the clamping protective structure 100 to protect the protective member 200, thereby improving the protective effect on the electrical equipment 500.
[0077] Combination Figure 7 Specifically, when there are two bending-resistant members 102, the support members 300 can be arranged in two layers. There can be two inner support members 300, which can be laid in the enclosed area formed between the two opposing sides of the two bending-resistant members 102 and the two limiting members 101. The outer support member 300 can be laid on top of the two inner support members 300 to protect the protective member 200. After the packaging cover is assembled, the two layers of support members 300 can be placed sequentially, making assembly quick and easy.
[0078] It should be noted that the packaging cover in this embodiment can be placed on the top and / or bottom of the electrical appliance to be protected, preferably on the top of the electrical appliance to be protected, so that it can bear the top load and allow the electrical appliance to be protected to be transported in a stacked manner, so as to have better transport capacity and reduce transportation costs.
[0079] Combination Figure 8 In order to reduce costs, in this embodiment of the application, a weight-reducing part 205 may be provided on the protective part 200 covering the support member 300. The weight-reducing part 205 may be hole-shaped or / and groove-shaped, and there is no limitation here.
[0080] In addition to the aforementioned packaging cover, this application also provides a packaging assembly that includes the aforementioned packaging cover.
[0081] The packaging assembly with the aforementioned clamping protection structure 100 can reduce the thickness of the bending member 102 while fully utilizing its compressive strength, thereby achieving the effect of resisting the same clamping load with the minimum thickness of the bending member 102. In addition, the protrusion 104 provided on the second side of the bending member 102 can constrain the middle of the bending member 102, reduce the bending deformation span of the bending member 102, increase the bending stiffness and stability of the bending member 102, and have a better buckling protection effect. This ensures that the components of the electrical equipment 500 are undamaged and the surface of the electrical equipment 500 is free from deformation, preventing plastic deformation of the electrical equipment 500 and improving the equipment protection effect of the electrical equipment 500.
[0082] Figure 9 For having Figure 2 The diagram shown is a structural representation of the packaging assembly, including the packaging cover. Figure 9 The packaging cover of the packaging component can cover the top of the electrical equipment 500 to be protected, while a base 400 supported by foam can be provided at the bottom of the electrical equipment 500 to form a wrapping effect of clamping from both above and below.
[0083] Of course, the packaging component can also be of other types, and there are no restrictions here.
[0084] Finally, based on the above-mentioned packaging components, this application also provides an electrical component, which includes an electrical appliance and the above-mentioned packaging components, with the electrical appliance enclosed inside the packaging components.
[0085] Electrical components with the aforementioned packaging elements can reduce the thickness of the bending members while fully utilizing the compressive strength of the clamping protective structure, thereby achieving the effect of resisting the same clamping load with the thinnest bending member. In addition, the protrusion provided on the second side of the bending member can constrain the middle of the bending member, reduce the bending deformation span of the bending member, increase the bending stiffness and stability of the bending member, and thus have a better buckling protection effect. This ensures that the electrical equipment components are undamaged and the appearance surface is free from deformation, thereby preventing plastic deformation of the electrical equipment and improving the equipment protection effect.
