[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The paper-wood combined battery module packaging box of the utility model is provided with a reinforcing structure inside, which enhances the load-bearing capacity and structural stability of the paper-wood combined packaging box, makes its performance close to that of a wooden box, is lighter than a wooden box, and has a lower cost than a wooden box.

[0029] See also Figures 1 to 11 As shown, a paper-wood combined battery module packaging box includes a wooden pallet 1 and four paper side panels placed on the wooden pallet, the side panels are connected together by corner guards to form an enclosure structure, a box cover 2 is arranged on the top of the enclosure structure, and a layer of plywood is fixed to the inner surface of the side panels for strengthening the side panels.

[0030] Specifically, the four paper side panels are composed of two long side panels 3 and two short side panels 4. The long side panels 3 serve as the front and rear sides of the packaging box, and the short side panels serve as the left and right sides of the packaging box. The inner surfaces of the long side panels have first plywood 31, and the inner surfaces of the short side panels have second plywood 41. The first plywood 31 and the second plywood 41 have the same structure, and only differ in size or dimensions.

[0031] In the present application, in order to improve the load-bearing capacity of the existing paper-wood combined battery module packaging box, a plywood structure is added to the long side panels and the short side panels, and the paper side panels are reinforced by the plywood, thereby solving to a certain extent the problem of low load-bearing capacity and easy deformation of the side panels of the existing paper-wood combined battery module packaging box.

[0032] As is well known, in a paper-wood combined battery module packaging box, the side panels are connected by plug-in means through corner guards 35 (such as paper corner guards) to form an enclosure structure, and are installed on the upper end of the wooden pallet 1, and the outer side is limited by the peripheral structure of the top of the wooden pallet. Furthermore, metal corner guards 6 are arranged on the inner side between adjacent side panels to connect the four side panels. Preferably, twelve metal corner guards 6 are used for connection, and every two adjacent side panels are connected by three metal corner guards spaced apart from each other. The metal corner guards are connected to the side panels by screws to make the packaging box structure stable, and the present application does not make any improvements to this.

[0033] As is known to all, in the paper-wood combined battery module packaging box, the wooden pallet 1 is used to place the battery module 100, and the battery module area of ​​the wooden pallet is provided with battery module limiting protrusions 14 around it, such as rectangular blocks, and the battery module limiting protrusions are multiple and arranged at intervals to limit the periphery of the battery module 100. The bottom of the wooden pallet has supporting wooden piers 12, which are multiple and arranged at intervals to support the top plate 11 of the wooden pallet and separate it from the supporting surface below. This application does not make any improvements to this. In some embodiments, in order to reduce the weight of the packaging box, part of the board body is cut off from the plywood, so that a weight-reducing notch is formed on the plywood, thereby reducing the weight of the plywood and then reducing the weight of the packaging box. The position of the weight-reducing notch can be selected as needed and can be any shape, not limited to the embodiments in the figure. For example, the first plywood 31 has a first weight-reducing notch 32, and the second plywood 41 has a second weight-reducing notch 42. Preferably, in order to facilitate the cutting of the equipment and improve the cutting efficiency of the plywood, the weight-reducing notches are arranged at both ends of the plywood in the height direction, and the weight-reducing notches on the same side are arranged separately, which can achieve the effect of reducing weight while ensuring structural strength.

[0034] Preferably, the weight-reducing notch is a rectangular notch. The weight-reducing notch is not limited to this shape, and can be other geometric shapes. For the convenience of cutting, a rectangular notch is preferred. In some preferred embodiments, the weight-reducing notch is a structure that is symmetrical up and down and / or symmetrical left and right. Of course, it can also be asymmetrical or of different sizes.

[0035] Preferably, the plywood is fixed to the side panels by bonding and / or nailing.

[0036] Furthermore, in some embodiments, the paper-wood combined battery module packaging box also includes a wooden reinforcing beam 5, which is preferably a plate-shaped structure and can be multiple, arranged in the enclosure structure formed by the side panels, with both ends connected to the inner sides of the two long side panels among the side panels. The wooden reinforcing beam can be one or multiple, with no specific limitation, and can support the packaging box in the width direction and / or length direction of the packaging box to prevent the packaging box from being compressed and deformed in the width direction and / or length direction.

[0037] Among them, in some embodiments, in order to facilitate the installation of the wooden reinforcement beam 5, a limiting groove 33 is formed at the upper end of the plywood of the long side panel to match the two ends of the wooden reinforcement beam, and the limiting groove is adapted to the shape of the two ends of the wooden reinforcement beam. The two ends of the wooden reinforcement beam are placed in the limiting groove, and its end surface is in contact with the inner surface of the long side panel. By arranging the wooden reinforcement beam in the enclosure structure, the two ends of the wooden reinforcement beam are connected to the inner side surfaces of the two long side panels in the side panels, and the structure of the overall packaging box is further strengthened.

[0038] In some embodiments, a limiting protrusion 51 is arranged near the two ends of the lower surface of the wooden reinforcing beam 5, and the limiting protrusion is perpendicular to the lower surface of the wooden reinforcing beam. After the two ends of the wooden reinforcing beam are placed in the limiting groove, the limiting protrusion contacts the surface of the plywood on the long side panel. Through the contact between the limiting protrusion and the surface of the plywood, a better reinforcing support effect can be achieved, making the packaging box more stable and meeting the packaging needs of the battery module.

[0039] In some embodiments, after the side panels are placed on the wooden pallet, the bottom of the plywood in contact with the top of the wooden pallet corresponds to the supporting wooden pier 12 at the bottom of the wooden pallet 1 to transfer force. By keeping the uncut portion of the plywood on the side panels consistent with the position of the wooden pier on the bottom pallet, the pressure can be transferred to the wooden pier, which is conducive to the stability and firmness of the structure. Taking the long side panels as an example, the support portion 34 corresponding to the supporting wooden pier located between the weight reduction notches corresponds to the supporting wooden pier 12 at the bottom of the wooden pallet 1.

[0040] In the present application, after the battery module 100 is placed in the packaging box and the box cover 2 is placed, the packaging box is also tied up with a strapping tape 7 to prevent the box cover from loosening from the box body and the wooden pallet.

[0041] In summary, the paper-wood combined battery module packaging box of the utility model, by fixing a layer of plywood for reinforcing the side panels on the inner surfaces of the side panels, can utilize the plywood to reinforce the paper side panels, thereby solving to a certain extent the problem of low load-bearing capacity and easy deformation of the side panels of the existing paper-wood combined battery module packaging boxes.
