[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] Reference Figure 1-5 As shown, this utility model discloses a paper card structure for packaging mobile phone chargers. The paper card structure is formed by folding a first original board 100. Specifically, the paper card structure includes a first side cardboard 12, a second side cardboard 13, a base plate 11, a step plate 15, and a baffle 14. Specifically, the first side cardboard 12 and the second side cardboard 13 are respectively connected to the base plate 11. The base plate 11 is connected to the step plate 15 and the baffle 14 in sequence. The first side cardboard 12 and the second side cardboard 13 are located on both sides of the base plate 11 and the step plate 15, respectively, to provide lateral buffer protection. The baffle 14 is inserted and connected to the first side cardboard 12 and the second side cardboard 13. The step plate 15 is located between the base plate 11 and the baffle 14. The charger body 20 is placed on the base plate 11 and is limited by the step plate 15, the first side cardboard 12, and the second side cardboard 13. The pins 21 on the charger body 20 abut against the baffle 14 to protect the pins 21. The step plate 15 is used to prevent the charger body 20 from moving towards the baffle 14.

[0028] Furthermore, the first side cardboard 12 and the second side cardboard 13 are symmetrically arranged on both sides of the base plate 11 and the step plate 15. This symmetrical design reduces the difficulty of processing and design. In addition, the first side cardboard 12 is perpendicular to the base plate 11 and the step plate 15, and the upper surfaces of the base plate 11 and the step plate 15 are parallel to each other. The baffle 14 is perpendicular to the first side cardboard 12 and the base plate 11, so that the first side cardboard 12, the second side cardboard 13, the base plate 11, the step plate 15, and the baffle 14 can form a stepped receiving cavity. The receiving cavity is open at the top and at one end, and is a regular structure composed of two cuboids. This receiving cavity can accommodate and limit the charger body 20.

[0029] Furthermore, both the first side cardboard 12 and the second side cardboard 13 are through-wall structures, serving as buffer protection for both sides of the charger body 20. Additionally, the vertical height of the step plate 15 is higher than that of the base plate 11; that is, the upper surface of the step plate 15 is higher than the upper surface of the base plate 11, and a step is provided at the contact point between the two. The charger body 20 uses this step as a support point, preventing it from moving towards the baffle 14. The length and width dimensions of the base plate 11 can be modified to accommodate different sizes of the charger body 20.

[0030] Furthermore, a mounting hole 150 is provided between the first side cardboard 12 and the second side cardboard 13, and a stepped plate 15 is disposed within the mounting hole 150. Additionally, slots 140 are provided on the first side cardboard 12 and the second side cardboard 13, and a baffle 14 is inserted into the slot 140. Moreover, the mounting hole 150 is located between the base plate 11 and the slot 140, and the mounting hole 150 and the slot 140 are interconnected. Specifically, the middle of the slot 140 communicates with the mounting hole 150, and both ends of the slot 140 extend outwards along the first side cardboard 12 and the second side cardboard 13, respectively.

[0031] Specifically, in combination Figure 3-5 As shown, the forming process of the paper card structure in this application is as follows: First, the raw material is die-cut to form a first base plate 100. The first base plate 100 includes a middle plate 101, a first folding plate 102, a second folding plate 103, a third folding plate 104, and a fourth folding plate 105, as well as corresponding creases. Through mounting holes 150 and slots 140 are machined between the middle plate 101, the first folding plate 102, and the second folding plate 103. Figure 3 As shown, with the front structure of the first original plate 100 facing upwards, the first folding plates 102 and 103 on both sides are first folded upwards by 90 degrees along both ends of the middle plate 101, and then folded outwards along their own creases to form a through-panel structure—the first side cardboard 12 and the second side cardboard 13. Then, both ends of the middle plate 101 are folded downwards by 90 degrees to partially cover the two side cardboards, wherein, as shown... Figure 4 As shown, from a perspective with the back structure of the first original plate 100 facing upwards, the third folding plate 104 and the fourth folding plate 105 are folded up respectively and are perpendicular to each other. The fourth folding plate 105 forms a step along the fold and covers the mounting hole 150, so that the third folding plate 104 is inserted into the slot 140 to complete the packaging. Figure 5 This is another perspective, viewing the reverse folding packaging design of the step plate 15 and the baffle 14 from the back structure of the first original plate 100 facing upwards. The creases facilitate the folding of the cardboard, ensuring that the folded cardboard structure has sharp edges and is aesthetically pleasing. The above processing method does not require the use of glue, resulting in high processing efficiency and low processing cost.

[0032] The improvement of this device lies in the fact that by adding internal steps and a reverse folding design, it solves the problems of insufficient strength around the perimeter and back-and-forth swaying in ordinary cushioning structures, which lead to poor cushioning performance and damage. At the same time, it can effectively replace packaging forms such as EPE and EPS, achieving the requirements of low-carbon and environmentally friendly packaging.

[0033] In this utility model device, the paper card structure is made of 350g cardboard. The folding method is simple, designed to increase the strength of the packaging around the phone box while maintaining its aesthetic appeal. The packaging operation is completed using a reverse folding and insertion method to secure the cardboard to the front. This packaging is mainly used for relatively regular-shaped mobile phone charger products and can be adjusted according to different product sizes. Compared to traditional packaging methods, it offers better cushioning performance. The cardboard material and die-cutting processing method are existing technologies or materials, which can be purchased directly from the market or custom-made by the relevant technical personnel based on the required product model and specifications.

[0034] The above description is merely a preferred embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It is obvious to those skilled in the art that this utility model is not limited to the details of the above embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
