Abstract
Description
Technical Field
[0001] This application relates to the technical field of product packaging, and particularly to a packaging box and a packaging structure for a controller. Background Art
[0002] When designing a packaging box, cost control needs to be the main consideration for whether to adopt this design solution. Therefore, when designing the entire set of packaging, in addition to being safe, stable, clean, beautiful, and user-friendly, low cost also needs to be the main design principle.
[0003] In the design of a packaging box, there will be some products. Due to their structural reasons, for example, the product includes a main body part and a secondary body part of the product. The secondary body part is smaller in volume than the main body part, and the secondary body part protrudes from the main body part. The area of the connection surface between the secondary body part and the main body part is smaller than the surface area of the main body part. When the product is placed in the product packaging box, the secondary body part protruding from the main body part is in a relatively suspended state. When the product drops, if the secondary body part of the product is hit first, the impact force will all be concentrated on the secondary body part, causing the connection part between the secondary body part and the main body part to be deformed by the force. In the prior art, materials are filled in the packaging box to fill the gap between the main body part and the secondary body part, so that when impacted, the materials can play a role in supporting the secondary body part and bearing the impact force, thereby preventing the connection part of the product from being deformed by the force. However, this method wastes materials, is not clean enough, and has a high cost. Moreover, the shape of the filled materials needs to be manufactured separately, increasing the design and production costs. Summary of the Utility Model
[0004] In view of the above problems, the embodiments of this application provide a packaging box and a packaging structure for a controller, with a simple structure, solving the problems of complex product packaging design and high cost.
[0005] In a first aspect, the present application provides a packaging box, which is formed by folding a cardboard along a preset crease and is used to accommodate a product. The product includes a main body portion and a protruding portion. A connecting surface is provided on the main body portion, and the protruding portion is located on the connecting surface. The packaging box includes: a bottom plate; a first side plate, a second side plate, a third side plate, and a fourth side plate. The first side plate and the second side plate are oppositely arranged, and the third side plate and the fourth side plate are oppositely arranged; the first side plate, the second side plate, the third side plate, and the fourth side plate are arranged along the periphery of the bottom plate and enclose a receiving cavity with the bottom plate, and the product is located in the receiving cavity. Among them, the main body portion abuts against the first side plate, and the protruding portion protrudes from the connecting surface towards the second side plate; a first support plate is provided on the third side plate or the fourth side plate. The first support plate includes a first folding structure connected to the third side plate or the fourth side plate and a second folding structure connected to the first folding structure; the first folding structure faces the bottom plate, and the second folding structure has a first support edge that abuts against the main body portion and a second support edge that abuts against the surface of the second side plate; a cover plate; the cover plate is connected to the first side plate or the second side plate and can cover the top surface of the receiving cavity.
[0006] Through the above solution, the protruding portion protrudes from the connecting surface towards the second side plate. A first support plate is provided on the third side plate or the fourth side plate. The first support plate includes a first folding structure connected to the third side plate or the fourth side plate and a second folding structure connected to the first folding structure. When the first folding structure and the second folding structure are folded, the first folding mechanism faces the bottom plate, and the second folding structure is folded from the cover plate direction towards the bottom plate direction. Since the second folding structure has a first support edge that abuts against the main body portion and a second support edge that abuts against the surface of the second side plate, that is to say, the first support edge and the second support edge respectively support on the main body portion and the second side plate. When the product drops or is impacted, it first receives the impact force. The force that should have acted between the protruding portion and the connecting surface is transferred to the first support edge and the second support edge. For example, if the protruding portion touches the ground first, the end face of the protruding portion will be impacted. Due to the setting of the first support plate, when the product touches the ground, the second support edge can bear most of the impact force; when the packaging box is impacted, the impact force between the protruding portion and the connecting surface will be dispersed by the first support edge and the second support edge, thereby reducing the direct impact. When the protruding portion touches the ground, the second support edge can bear most of the impact force, protecting the connection between the protruding portion and the main body portion from damage. This design avoids the stress at the connection, reduces the risk of deformation caused by stress, and ensures the safety of the product. This design not only improves the practicability of the packaging box, but also reduces the material usage, achieving the dual goals of cost-effectiveness and environmental friendliness. It effectively improves the durability and protection performance of the packaging box.
[0007] In a possible design, first support plates are provided on both the third side plate and the fourth side plate. The first folding structure of one of the first support plates covers the top surface of the protruding portion, and the side edges of the first folding structure abut against the main body portion and the second side plate respectively; or, the second folding structure of one of the first support plates abuts against the protruding portion.
[0008] Through the above solution, first support plates are provided on both the third side plate and the fourth side plate, which is equivalent to providing protection on both sides of the protruding portion. When landing or being impacted, the first support edges and the second support edges on both sides jointly bear the impact force, which can better protect the protruding portion and the connection, avoid the protruding portion and the main body portion from deforming due to force, and ensure the safety of the product. The first folding structure of one of the first support plates covers the top surface of the protruding portion, which is equivalent to one of the first support plates surrounding and protecting the protruding portion. That is, the first folding structure is above the protruding portion, and there is also a second folding structure on the side. The first support edge of the second folding structure abuts against the main body portion, and the second support edge abuts against the second side plate, which can better avoid the protruding portion from being stressed and improve the safety of the product.
[0009] Similarly, the second folding structure of one of the first support plates abuts against the protruding portion, which is equivalent to having a second folding structure close to the protruding portion. Then, there is a first folding structure above the corresponding protruding portion. The side facing the main body portion and the other side facing the second side plate of the first folding structure have a protective effect on the protruding portion. The first support edge of the second folding structure abuts against the main body portion, and the second support edge abuts against the second side plate. That is, the second folding structure also has a protective effect on the protruding portion. Therefore, the first support plate can well protect the protruding portion, avoid the protruding portion from being stressed, and improve the safety of the product.
[0010] In a possible design, the distance from the third side plate to the fourth side plate is the first distance D1; the first folding structure extends from the third side plate to the fourth side plate or from the fourth side plate to the third side plate, and the extended length L satisfies: 1 / 3D1 ≤ L ≤ 2 / 3D1.
[0011] Through the above solution, first support plates are provided on both the third side plate and the fourth side plate. The protruding part may be on the side close to the third side plate and away from the fourth side plate, or may be on the side close to the fourth side plate and away from the third side plate. Relatively speaking, the part in the accommodation cavity without the protruding part is empty. The purpose of the first support plate away from the protruding part is to support this part of the cavity to ensure the overall balance inside the packaging box. Since some operation switches are usually set at the position from 1 / 3D1 to 2 / 3D1 of the center of the main body part in general products, and the operation switches also need to be protected. When the extension length of the first folding structure is 1 / 3D1 ≤ L ≤ 2 / 3D1, this can not only ensure the balance of the overall design, but also ensure that the area of the operation switch is not stressed, thereby protecting the overall product.
[0012] In a possible design, the height of the protruding part protruding from the connecting surface towards the second side plate is the second distance D2; the distance between the first support edge and the second support edge is the third distance D3, and D3 ≥ D2.
[0013] Through the above solution, the distance between the first support edge and the second support edge is greater than the height of the protruding part protruding from the connecting surface towards the second side plate, so that there is enough gap between the protruding part and the first support edge or the second support edge. When the product touches the ground or receives an impact force, the first support edge or the second support edge is stressed, but it cannot touch the internal protruding part at all. Therefore, the protruding part will not be affected by the impact force, ensuring the safety of the protruding part.
[0014] In a possible design, the main body part has a concave structure near the third side plate or the fourth side plate, and the concave structure is recessed relative to the upper surface of the main body part; the packaging box further includes a second support plate, the second support plate is provided on the third side plate or the fourth side plate and corresponds to the position of the concave structure; the second support plate includes a third folding structure connected to the third side plate or the fourth side plate and a fourth folding structure connected to the third folding structure, the third folding structure covers the concave structure, and the fourth folding structure extends into the concave structure and abuts against the main body part.
[0015] Through the above solution, the main body part of the product may not be a regular cube. Therefore, the main body part of some products also needs to be protected. A second support plate is provided on the third side plate or the fourth side plate corresponding to the concave structure. Since the second support plate includes a third folding structure connected to the third side plate or the fourth side plate and a fourth folding structure connected to the third folding structure, the third folding structure covers the concave structure, and the fourth folding structure extends into the concave structure and abuts against the main body part, it can prevent the main body part from shaking in the accommodation cavity and ensure the safety of the product.
[0016] In a possible design, in the direction from the first side plate to the second side plate, the recessed structure penetrates through the main body; the third folding structure faces the bottom plate, and the fourth folding structure has a third supporting edge that abuts against the first supporting plate and a fourth supporting edge that abuts against the surface of the first side plate.
[0017] With the above solution, when the recessed structure penetrates through the main body, the third folding structure faces the bottom plate, and the fourth folding structure has a third supporting edge that abuts against the first supporting plate and a fourth supporting edge that abuts against the surface of the first side plate. In this way, the setting of the second supporting plate can not only prevent the main body from shaking in the accommodating cavity, but also because the third supporting edge and the fourth supporting edge respectively abut against the surface of the first side plate and the first supporting plate, the main body is also protected. When impacted, the third supporting edge and the fourth supporting edge first contact the impact object, preventing the main body from being impacted.
[0018] In a possible design, the cover plate includes a main cover part and a locking cover part. The main cover part is connected to the first side plate or the second side plate, and a first insertion slot is provided on the main cover plate. The locking cover part can be inserted through the first insertion slot to lock the locking cover part.
[0019] With the above solution, the main cover part can cover the accommodating cavity, and the insertable locking cover part can lock the main cover part, locking the product in the packaging box.
[0020] In a second aspect, the present application provides a packaging structure for a controller, including a controller and the packaging box of the first aspect.
[0021] With the above solution, placing the controller in the packaging box can prevent the protruding part and the main body part in the controller from being deformed due to force, ensuring the safety of the controller. And this design does not require extra materials. Only the first folding structure and the second folding structure need to be designed at the corresponding positions of the packaging box. The structure is simple, without the design and manufacture of extra materials, and the cost is low.
[0022] In a possible design, the controller includes a main body part and a protruding part. The main body part has a connecting surface, and the protruding part is located on the connecting surface. The protruding part protrudes from the connecting surface towards the second side plate, and the protruding part is close to the third side plate; first supporting plates are provided on both the third side plate and the fourth side plate. The first folding structure of the first supporting plate on the third side plate covers the protruding part, and the second folding structure abuts against the protruding part.
[0023] With the above solution, first supporting plates are provided on both the third side plate and the fourth side plate. When the protruding part is close to the third side plate, the first folding structure on the third side plate covers the protruding part, and the second folding structure abuts against the protruding part. In this way, the protruding part can be better protected, preventing the protruding part from being impacted.
[0024] In a possible design, an operating switch is provided on the main body of the leakage protector. The operating switch is located in the middle of the main body, and protrudes relative to the upper surface of the main body. Concave recessed structures are respectively provided on both sides of the operating switch relative to the upper surface of the main body, and the recessed structures penetrate the main body in the direction from the first side plate to the second side plate; the heights of the third side plate and the fourth side plate are greater than the height of the controller from the bottom to above the operating switch.
[0025] Through the above solution, the heights of the third side plate and the fourth side plate are greater than the height of the controller from the bottom to above the operating switch. Therefore, there is a gap between the third folding structure in the second support plate provided on the third side plate and the fourth side plate and above the operating switch. When an impact force is applied above the controller, the third folding structure first contacts the impact object, avoiding the operating switch from being impacted, thus better protecting the safety of the controller.

[0044] A packaging box is generally a box used to package products. Figure 1 It is a packaging box in the prior art. Please refer to Figure 1 , Figure 1 The shape and structure of the product 20 therein is not a regular cube structure. When it is placed in the packaging box 10, the packaging box 10 cannot protect it. However, due to its structural reasons, when these products 20 are placed in the packaging box, once they fall or are impacted, the internal products 20 may be damaged and unusable.
[0045] In the related art, some additional materials are designed to cooperate with the product, and these materials are placed in the packaging box to fill the hollow parts in the product, so as to prevent the product from shaking or being damaged by impact in the packaging box. However, this method wastes materials, is not tidy enough, and has a high cost. Moreover, the shape of the filled materials needs to be manufactured separately, increasing the design and production costs.
[0046] Figure 2 Schematic diagram of the first support plate and the second support plate of the packaging box provided in this embodiment without being folded. Figure 3 Schematic diagram of the state where the first support plate and the second support plate of the packaging box provided in this embodiment are folded to form protection. Figure 4 Schematic diagram of the unfolded state of the packaging box provided in the present embodiment. Please refer to Figures 2 to 4 , the packaging box 100 provided in this embodiment is formed by folding a cardboard along a preset crease and is used to accommodate the product. The packaging box 100 includes: a bottom plate, side plates, a first support plate 210 and a cover plate.
[0047] The bottom plate serves as the bottom basic part of the packaging box 100 and is used to support the product 20. The bottom plate can be an integral material. When the packaging box 100 is unfolded, it can be connected to the first side plate 121, the second side plate 122, the third side plate 123 or the fourth side plate 124. As Figure 4 shown, the bottom plate in this embodiment is formed by folding and splicing a first bottom piece 111 connected to the first side plate 121, a second bottom piece 112 connected to the second side plate 122, a third bottom piece 113 connected to the third side plate 123, and a fourth bottom piece 114 connected to the fourth side plate 124.
[0048] There are four side plates in total, which are divided into two pairs of relatively arranged side plates, namely the relatively arranged first side plate 121 and the second side plate 122, and the relatively arranged third side plate 123 and the fourth side plate 124. These side plates are arranged along the outer peripheral edge of the bottom plate and jointly enclose a receiving cavity with the bottom plate, and the product is placed in the receiving cavity.
[0049] Figure 6 Top view schematic diagram of the product provided in the embodiment of the present application. Please refer to in combination with Figure 6 , the product 20 includes a main body part 21 and a protruding part 22. The main body part 21 has a connecting surface, and the protruding part 22 is located on the connecting surface. When the product 20 is placed in the receiving cavity, the main body part 21 abuts against the first side plate 121, and the protruding part 22 protrudes from the connecting surface towards the second side plate 122.
[0050] The first support plate 210 is disposed on the third side plate 123 or the fourth side plate 124. The first support plate 210 includes a first folding structure 211 connected to the third side plate 123 or the fourth side plate 124 and a second folding structure 212 connected to the first folding structure 211. The first folding structure 211 faces the bottom plate, and the second folding structure 212 has a first support edge abutting against the main body portion 21 and a second support edge abutting against the surface of the second side plate 122.
[0051] In this embodiment, when the first folding structure 211 and the second folding structure 212 are folded, the first folding mechanism faces the bottom plate, and the second folding structure 212 is folded from the cover plate direction towards the bottom plate direction. Since the second folding structure 212 has a first support edge abutting against the main body portion 21 and a second support edge abutting against the surface of the second side plate 122, that is to say, the first support edge and the second support edge are respectively supported on the main body portion 21 and the second side plate 122. When the product 20 drops or is impacted, it first receives the impact force, and the force that should have acted between the protruding portion 22 and the connection surface is transferred to the first support edge and the second support edge. For example, if the protruding portion 22 touches the ground first, the end face of the protruding portion 22 will be impacted. Due to the arrangement of the first support plate 210, when the product 20 touches the ground, the second support edge can bear most of the impact force. In addition, when the protruding portion 22 touches the ground and is impacted, it will cause the connection between the protruding portion 22 and the main body portion 21 to be squeezed, resulting in damage or deformation. Since the first support edge abuts against the main body portion 21 and the second support edge abuts against the second side plate 122, this avoids the connection from being stressed, thereby preventing the protruding portion 22 and the main body portion 21 from deforming due to stress and ensuring the safety of the product 20. And this design does not require extra materials. Only the first folding structure 211 and the second folding structure 212 need to be designed at the corresponding positions of the packaging box 100. The structure is simple and does not require the design and manufacture of extra materials, with low cost.
[0052] According to the structure of different products 20, when placed in the packaging box 100, the position where the protruding portion 22 is located will be different. For example, the protruding portion 22 of some products 20 may be located between the third side plate 123 and the fourth side plate 124, the protruding portion 22 of some products 20 may be close to the third side plate 123, or the protruding portion 22 of some products 20 may be close to the fourth side plate 124.
[0053] When the protrusion 22 of the product 20 is located between the third side plate 123 and the fourth side plate 124, first support plates 210 can be provided on both the third side plate 123 and the fourth side plate 124. Moreover, the first support plate 210 on the third side plate 123 and the first support plate 210 on the fourth side plate 124 are respectively arranged on both sides of the protrusion 22. Providing first support plates 210 on both the third side plate 123 and the fourth side plate 124 is equivalent to providing protection on both sides of the protrusion 22. When the product lands or is impacted, the impact force is jointly borne by the first support edges and the second support edges on both sides, which can better protect the protrusion 22 and the connection part, prevent the protrusion 22 and the main body part 21 from deforming due to force, and ensure the safety of the product 20.
[0054] Furthermore, the second folding structure 212 connected to the third side plate 123 can abut against the side of the protrusion 22 facing the third side plate 123, and the second folding structure 212 connected to the fourth side plate 124 can abut against the side of the protrusion 22 facing the fourth side plate 124. In this way, support is provided on both sides of the protrusion 22 to prevent damage during transportation or storage. Moreover, through the contact between the second folding structure 212 of the first support plate 210 and the protrusion 22, the fixing effect of the packaging box 100 on the product 20 is enhanced, and the movement and vibration during transportation are reduced.
[0055] When the protrusion 22 of the product 20 is close to the third side plate 123 or close to the fourth side plate 124, first support plates 210 can be provided on both the third side plate 123 and the fourth side plate 124. The first folding structure 211 of one of the first support plates 210 covers the top surface of the protrusion 22, and the side edges of the first folding structure 211 respectively abut against the main body part 21 and the second side plate 122.
[0056] To accommodate different positions of the protrusion 22, first support plates 210 are provided on both the third side plate 123 and the fourth side plate 124. The first support plates 210 provide additional support and protection for the protrusion 22. When the protrusion 22 is close to either side plate, for example, close to the third side plate 123, the first folding structure 211 of the first support plate 210 on the third side plate 123 will cover the top surface of the protrusion 22 to prevent the protrusion 22 from moving or being compressed within the packaging box 100. The side edges of the first folding structure 211 are designed to abut against the main body portion 21 of the product 20 and the second side plate 122, so that even during transportation or handling, the protrusion 22 can remain stable, reducing the risk of damage due to vibration or impact. If the protrusion 22 is close to the fourth side plate 124, then the first folding structure 211 of the first support plate 210 on the fourth side plate 124 will perform a similar function, that is, covering the top surface of the protrusion 22 and abutting against the main body portion 21 and the second side plate 122 with its side edges. This design allows the packaging box 100 to accommodate products 20 of different shapes, especially those with protrusions 22 at different positions, providing a flexible and effective protection method. The structural design of the entire packaging box 100 takes into account the safety and stability of the product 20, ensuring that the product 20 can be properly protected in various transportation environments.
[0057] Based on the above solution, the first folding structure 211 of a first support plate 210 covers the top surface of the protrusion 22. The first folding structure 211 is a foldable part that can cover and fit on the top surface of the protrusion 22 of the product 20. When the product 20 is placed in the packaging box 100 and its protrusion 22 is close to the third side plate 123 or the fourth side plate 124, the corresponding first folding structure 211 of the first support plate 210 will cover and fit on the top surface of the protrusion 22, thereby providing additional protection for the protrusion 22. The side edges of the first folding structure 211 are designed to abut against the main body portion 21 of the product 20 and the second side plate 122 to ensure the stability of the protrusion 22 within the packaging box 100 and prevent it from moving or being impacted during transportation.
[0058] The second folding structure 212 of one of the first support plates 210 abuts against the protruding portion 22. The second folding structure 212 is provided on each first support plate 210, which is the foldable part of the first support plate and can directly contact and provide support for the protruding portion 22 of the product 20. The protruding portion 22 of the product 20 is located on the connecting surface of the main body portion 21 and protrudes between the third side plate 123 and the fourth side plate 124. The specific position of the protruding portion 22 determines which second folding structure 212 of the first support plate 210 will abut against it. When the protruding portion 22 of the product 20 is close to the third side plate 123, the second folding structure 212 of the first support plate 210 on the third side plate 123 will abut against one side of the protruding portion 22. Similarly, if the protruding portion 22 is close to the fourth side plate 124, then the second folding structure 212 of the first support plate 210 on the fourth side plate 124 will abut against the other side of the protruding portion 22. The abutting action between the second folding structure 212 and the protruding portion 22 ensures that the protruding portion 22 has a stable support point in the packaging box 100, reducing the risk of damage due to vibration or impact during transportation or storage. This design enhances the stability of the protruding portion 22 in the packaging box 100 by providing direct physical support, ensuring the overall safety of the product 20. This design of the packaging box 100 has good adaptability and can be adjusted according to the specific position of the protruding portion 22 of the product 20 to ensure the best support effect. After assembly, the second folding structure 212 of the first support plate 210 is tightly combined with the protruding portion 22 of the product 20, ensuring the integrity and protection performance of the entire packaging box 100.
[0059] In this embodiment, the distance from the third side plate 123 to the fourth side plate 124 is the first distance D1; the first folding structure 211 extends from the third side plate 123 to the fourth side plate 124 or from the fourth side plate 124 to the third side plate 123, and the extended length L satisfies: 1 / 3D1 ≤ L ≤ 2 / 3D1.
[0060] The extension length L of the first folding structure 211 of the first support plate 210 is carefully designed to ensure proper fitting and support for the protrusion 22 of the product 20. In the design of the packaging box 100, the distance between the third side plate 123 and the fourth side plate 124 is defined as the first distance D1. This distance is an important dimension in the design of the packaging box 100 and affects the extension length of the first folding structure 211 of the first support plate 210. The first folding structure 211 on the first support plate 210 is designed to be foldable and can extend from the third side plate 123 towards the fourth side plate 124, or vice versa, from the fourth side plate 124 towards the third side plate 123. The extension length L of the first folding structure 211 is designed to meet a specific size range, i.e., 1 / 3D1 ≤ L ≤ 2 / 3D1. This means that the extension length of the first folding structure 211 is at least one-third of the first distance D1 but not more than two-thirds of D1. By precisely controlling the extension length of the first folding structure 211, proper support for the protrusion 22 can be ensured while avoiding space waste or instability caused by excessive extension. This design provides a certain degree of flexibility, allowing the first folding structure 211 to be adjusted according to the specific size and shape of the product 20 to achieve the best support effect. By restricting the extension length of the first folding structure 211, the stability of the protrusion 22 within the packaging box 100 can be ensured, reducing movement or vibration during transportation or storage. After assembly, the fitting of the first folding structure 211 with the protrusion 22 ensures the integrity and protective performance of the entire packaging box 100.
[0061] In a possible design, the height by which the protrusion 22 protrudes from the connection surface towards the second side plate 122 is the second distance D2, and the distance between the first support edge and the second support edge is the third distance D3, where D3 ≥ D2.
[0062] The protrusion 22 of the product 20 protrudes from the connection surface towards the second side plate 122, and the protruding height is defined as the second distance D2. This dimension is crucial as it determines the space requirement of the protrusion 22 within the packaging box 100 and the required support structure. The distance between the first support edge and the second support edge is defined as the third distance D3. This distance is an important parameter in the design as it affects how the second folding structure 212 of the first support plate 210 interacts with the protrusion 22. It is clearly stated in the design that the third distance D3 must be greater than or equal to the second distance D2. This means that the second folding structure 212 of the first support plate 210 can cover the entire height of the protrusion 22 and even more after being unfolded, leaving enough gaps between the protrusion 22 and the first support edge or the second support edge. When the product 20 touches the ground or receives an impact force, the first support edge or the second support edge bears the force but cannot touch the internal protrusion 22 at all. Therefore, the protrusion 22 will not be impacted, ensuring the safety of the protrusion 22. This design provides the ability to adapt to protrusions 22 of different heights. By simply adjusting the size and shape of the first support plate 210, the requirements of different products 20 can be met. With an appropriate distance between the support edges, the position of the protrusion 22 within the packaging box 100 is more stable, reducing movement during transportation and improving the safety of the product 20.
[0063] D3 is greater than D2, and the specific difference can be appropriately adjusted according to the weight of the specific product. In this embodiment, the range of D3 - D2 is 3 mm - 6 mm, avoiding D3 being too large and preventing the size of the packaging box 100 from not matching the size of the product 20, thus wasting material resources.
[0064] Figure 5 This is another schematic diagram of the unfolded state of the packaging box 100 provided in this embodiment. Figure 7 is Figure 6 a rear view schematic diagram of the product. Please refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 In this embodiment, near the position of the third side plate 123 or the fourth side plate 124 of the main body 21, there is a recessed structure 23, and the recessed structure 23 is concave with respect to the upper surface of the main body 21; the packaging box 100 further includes a second support plate 220, the second support plate 220 is arranged on the third side plate 123 or the fourth side plate 124 and corresponds to the position of the recessed structure 23; the second support plate 220 includes a third folding structure 221 connected to the third side plate 123 or the fourth side plate 124 and a fourth folding structure 222 connected to the third folding structure 221, the third folding structure 221 covers the recessed structure 23, and the fourth folding structure 222 extends into the recessed structure 23 and abuts against the main body 21.
[0065] The main body 21 of the product 20 is designed with a recessed structure 23, which is concave with respect to the upper surface of the main body 21. This design can provide additional support points for the product 20 within the packaging box 100. The packaging box 100 contains a second support plate 220, which is disposed on the third side plate 123 or the fourth side plate 124 and corresponds to the position of the recessed structure 23 of the main body 21 of the product 20. Such a layout ensures that the second support plate 220 can effectively cooperate with the recessed structure 23 of the product 20. The second support plate 220 includes two parts: a third folding structure 221 and a fourth folding structure 222. The third folding structure 221 is connected to the third side plate 123 or the fourth side plate 124, and the fourth folding structure 222 is connected to the third folding structure 221. The third folding structure 221 is designed to cover the recessed structure 23 of the product 20 and provide upward support for it to prevent the product 20 from moving up and down within the packaging box 100. The fourth folding structure 222 is designed to extend into the recessed structure 23 of the product 20 and abut against the main body 21, thereby providing lateral support to prevent the product 20 from shaking and enhancing the stability of the product 20. By the combined use of the third folding structure 221 and the fourth folding structure 222, the packaging box 100 can provide all-round support for the recessed structure 23 of the product 20, ensuring the stability and safety of the product 20 during transportation and storage. This design allows the packaging box 100 to adapt to products 20 with different recessed structures 23. By simply adjusting the shape and size of the second support plate 220, the requirements of different products 20 can be met. After assembly, the third folding structure 221 and the fourth folding structure 222 of the second support plate 220 are tightly combined with the recessed structure 23 of the product 20, ensuring the integrity and protective performance of the entire packaging box 100.
[0066] In this embodiment, in the direction from the first side plate 121 to the second side plate 122, the recessed structure 23 penetrates through the main body 21; the third folding structure 221 faces the bottom plate, and the fourth folding structure 222 has a third support edge abutting against the first support plate 210 and a fourth support edge abutting against the surface of the first side plate 121.
[0067] The main body 21 of the product 20 in the previous embodiment has a recessed structure 23 that runs through the entire main body 21 along the direction from the first side plate 121 to the second side plate 122. This design can provide additional support and fixing points for the product 20 within the packaging box 100. The second support plate 220 is provided on the third side plate 123 or the fourth side plate 124 and corresponds to the recessed structure 23 of the main body 21. Such a layout ensures that the second support plate 220 can effectively cooperate with the recessed structure 23 of the product 20. The third folding structure 221 on the second support plate 220 is designed to face the bottom plate. This means that when the packaging box 100 is assembled, the setting of the second support plate 220 can not only prevent the main body 21 from shaking in the accommodation cavity. The fourth folding structure 222 on the second support plate 220 has two supporting edges, namely the third supporting edge and the fourth supporting edge. The third supporting edge abuts against the first support plate 210, while the fourth supporting edge abuts against the surface of the first side plate 121. The third supporting edge abuts against the first support plate 210 to provide lateral support for the recessed structure 23 of the product 20, enhancing the stability of the product 20 within the packaging box 100. The fourth supporting edge abuts against the first side plate 121 to provide additional lateral support for the recessed structure 23 of the product 20, ensuring that the product 20 does not move laterally within the packaging box 100. Through the combined use of the third folding structure 221 and the fourth folding structure 222, the packaging box 100 can provide all-round support for the recessed structure 23 of the product 20, ensuring the stability and safety of the product 20 during transportation and storage. This design allows the packaging box 100 to adapt to products 20 with different recessed structures 23. By simply adjusting the shape and size of the second support plate 220, the requirements of different products 20 can be met.
[0068] The cover plate is connected to the first side plate 121 or the second side plate 122 and can cover the top of the accommodation cavity to protect the internal product 20 from damage
[0069] In this embodiment, the cover plate includes a main cover portion 130 and a locking cover portion 132. The main cover portion 130 is connected to the first side plate 121 or the second side plate 122, and a first slot 131 is provided on the main cover plate. The locking cover portion 132 can be inserted through the first slot 131 for locking the locking cover portion 132.
[0070] When the main cover part 130 is connected to the first side plate 121, the locking cover part 132 is correspondingly connected to the second side plate 122. When the main cover part 130 is connected to the second side plate 122, the locking cover part 132 is correspondingly connected to the first side plate 121. After assembly, the connection between the main cover part 130 and the first side plate 121 or the second side plate 122 covers the main cover part 130 on the accommodating cavity. At the position where the first slot 131 is directly opposite to the locking cover part 132, the locking cover part 132 is inserted into the first slot 131 in a matching manner to lock the main cover part 130 and lock the product 20 in the packaging box 100.
[0071] This embodiment also provides a packaging structure for a controller, including the controller and the packaging box in any of the previous embodiments.
[0072] The controller can be a leakage protection controller, which includes a main body part and a protruding part. The main body part has a connection surface, and the protruding part is located on the connection surface.
[0073] Placing the controller in the packaging box can prevent the protruding part and the main body part in the controller from deforming due to force, ensuring the safety of the controller. And this design does not require extra materials. Only the first folding structure and the second folding structure need to be designed at the corresponding positions of the packaging box. The structure is simple and does not require the design and manufacture of extra materials, with low cost.
[0074] When the controller is placed in the packaging box, the protruding part protrudes from the connection surface towards the second side plate, and the protruding part is close to the third side plate; first support plates are provided on both the third side plate and the fourth side plate. The first folding structure of the first support plate located on the third side plate covers the protruding part, and the second folding structure abuts against the protruding part. First support plates are provided on both the third side plate and the fourth side plate. When the protruding part is close to the third side plate, the first folding structure provided on the third side plate covers the protruding part, and the second folding structure abuts against the protruding part, which can better protect the protruding part and prevent the protruding part from being impacted.
[0075] In this embodiment, an operation switch is provided on the main body part of the leakage protector. The operation switch is in the middle of the main body part, and the operation switch protrudes relative to the upper surface of the main body part. Depressed structures that are concave relative to the upper surface of the main body part are respectively provided on both sides of the operation switch, and the depressed structures penetrate the main body part in the direction from the first side plate to the second side plate; the heights of the third side plate and the fourth side plate are greater than the height of the controller from the bottom to above the operation switch.
[0076] Through the above solution, the heights of the third side plate and the fourth side plate are greater than the height of the controller from the bottom to above the operation switch. As a result, there is a gap between the third folding structure in the second support plate provided on the third side plate and the fourth side plate and above the operation switch. When the controller is impacted above, the third folding structure first contacts the impact object, avoiding the operation switch from being impacted, thus better protecting the safety of the controller.
[0077] The height by which the third side plate and the fourth side plate are higher than the height of the controller from the bottom to above the operation switch can be appropriately adjusted according to the weight of the specific product. In this embodiment, the height by which the third side plate and the fourth side plate are higher than the height of the controller from the bottom to above the operation switch is 3 mm - 5 mm. This additional height provides an appropriate gap to accommodate the protruding part of the operation switch and ensures that the controller is fully protected in the packaging box. The 3 - 5 mm gap not only protects the operation switch from direct impact but also provides a buffer space for possible vibrations during transportation. When designing the third side plate and the fourth side plate, the maximum size of the controller needs to be considered. The exceeding height of the third side plate and the fourth side plate is preferably not more than 5 mm to avoid too large an overall gap between the size of the controller and the size of the packaging box, resulting in waste of packaging box materials.
[0078] The above embodiments are only used to illustrate the technical solutions of the present application, not to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the present application in each embodiment.
