[0034] The following is combined with Figure 1-7 This application is described in further detail.

[0035] The present application embodiment discloses a foam box with a supporting structure. Figure 1 The foam box with a supporting structure includes a foam box body 1 and a rigid body 2. The rigid body 2 is arranged inside the foam box body 1. The rigidity of the rigid body 2 material is greater than the rigidity of the foam box body 1 material.

[0036] Reference Figure 1 and Figure 2 The foam box body 1 comprises a box body 11 and a box cover 12. The box body 11 is provided with a receiving groove 13 for receiving the product, and the box body 11 and the box cover 12 are arranged to cover each other. The box body 11 and the box cover 12 are directly foamed by using materials such as polystyrene (PS) and polyurethane; in this embodiment, the box body 11 and the box cover 12 are made of polystyrene (PS).

[0037] Reference Figure 1 The rigid body 2 is inserted and fixed with the inner wall of the box body 11, and one end of the rigid body 2 is in contact with the bottom wall of the box body 11, and the other end of the rigid body 2 is in contact with the box cover 12, and the rigid bodies 2 of the upper and lower foam boxes are located on the same vertical line. In this embodiment, four rigid bodies 2 are provided, and the four rigid bodies 2 are arranged at the four corners of the box body 11.

[0038] Reference Figures 3 to 5The rigid body 2 includes a cylinder 21, a reinforcement 22, an ear plate 23 and a flexible member 24. The reinforcement 22 is arranged inside the cylinder 21, and the reinforcement 22 and the cylinder 21 are integrally formed; thereby improving the overall rigidity of the cylinder 21 and improving the supporting effect of the rigid member. The cylinder 21 is provided with a first protrusion 25 and a second protrusion 26 on the side close to the short side of the box 11. The first protrusion 25 and the second protrusion 26 are hollow structures. The first protrusion 25 and the second protrusion 26 are arranged at intervals. The inner side of the box 11 is provided with a first plug-in groove 111 for the first protrusion 25 to be plugged in, and a second plug-in groove 112 for the second protrusion 26 to be plugged in; thereby improving the connection strength of the rigid member to the box 11. Along the direction away from the ear plate 23, the width of the second protrusion 26 increases gradually; that is, the second protrusion 26 is engaged with the inner wall of the box 11, so that the rigid member is fixedly connected to the box 11, and it is also convenient for the staff to install the rigid member.

[0039] Reference Figures 3 to 5 The ear plate 23 is arranged opposite to the first protrusion 25, and the ear plate 23 is arranged vertically on the cylinder 21. The ear plate 23 and the cylinder 21 are formed as one piece, and the ear plate 23 and the cylinder 21 form two internal angles; wherein, the internal angle of the ear plate 23 away from the inner wall of the box body 11 is the first internal angle, and the internal angle of the ear plate 23 close to the inner wall of the box body 11 is the second internal angle.

[0040] Reference Figure 6 and Figure 7 , the two ear plates 23 arranged along the long side of the box body 11 are located on the same straight line, so that the four rigid parts divide the receiving groove 13 into a first receiving groove 131 and a second receiving groove 132; wherein, the second receiving groove 132 is provided with two sides, and the second receiving grooves 132 on both sides are arranged on both sides of the first receiving groove 131. The first inner corner is arranged in the first receiving groove 131, and the second inner corner is arranged in the second receiving groove 132. An installation gap is arranged between the ear plate 23 and the inner side wall of the foam box body 1, and the installation gap is used to accommodate additional products. That is, one foam box can accommodate two different products, reducing the mold opening amount of the mold and saving costs.

[0041] Reference Figure 6 and Figure 7 In this embodiment, the first receiving groove 131 is used to receive the product, and the second receiving groove 132 is used to receive the additional item. In this embodiment, the product is the LCD screen 7, and the additional item is the PBC board 8; a plurality of LCD screens 7 are stacked in the first receiving groove 131. The first inner corner of the rigid body 2 is used to abut against the LCD screen 7, and the four rigid bodies 2 are used to constrain the movement of the LCD screen 7 to fix the position of the LCD screen 7.

[0042] At the same time, an arc-shaped groove 5 is provided at the top corner of the first inner corner of the cylinder 21, and the arc-shaped groove 5 is used to avoid the corner of the liquid crystal screen 7 to reduce the extrusion wear between the corner of the liquid crystal screen 7 and the rigid part.

[0043] Reference Figure 3 and Figure 7 The flexible member 24 includes a first flexible member 241 and a second flexible member 242. The first flexible member 241 is bonded and fixed to the ear plate 23, and the second flexible member 242 is bonded and fixed to the cylinder 21. The first flexible member 241 and the second flexible member 242 are arranged at the first inner corner, and the flexible member 24 is used to abut against the liquid crystal screen 7. By arranging the flexible member 24 at the first inner corner, the flexible member 24 abuts against the main product, thereby fixing the position of the main product and reducing the collision wear of the main product. At the same time, the flexible member 24 abuts against the main product, which can reduce the wear of the main product. In this embodiment, the flexible member 24 is made of rubber material.

[0044] In this embodiment, the cylinder 21, the reinforcement 22, the first protrusion 25, the second protrusion 26 and the ear plate 23 are formed by one-time injection molding of TPU material, so that the rigid body 2 has greater rigidity and hardness. In other embodiments, the rigid body 2 can also be made of rigid materials such as stainless steel and aluminum alloy.

[0045] Reference Figure 3 The foam box also includes an adhesive member 6, which is disposed between the rigid body 2 and the box body 11, and is used to bond the rigid body 2 and the box body 11. The staff dispenses adhesive onto the first protrusion 25 and the second protrusion 26, and then the staff inserts and fixes the rigid member and the box body 11; after the adhesive solidifies and hardens, the adhesive member 6 is formed, and the rigid member and the box body 11 are bonded and fixed, so as to further improve the connection stability between the rigid member and the box body 11.

[0046] The implementation principle of a foam box with a support structure in the embodiment of the present application is:

[0047] However, during the transportation and storage of the LCD screen 7, several foam boxes are stacked; since the rigid component has greater rigidity, and one end of the rigid component abuts against the bottom wall of the box body 11, and the other end of the rigid component abuts against the box cover 12, the rigid component has a supporting effect on the LCD screen 7 in the box body 11; the squeezing of the upper foam box on the LCD screen 7 in the lower foam box can be reduced, thereby reducing the risk of damage to the LCD screen 7.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
