The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

A combined EPS packaging box for an automobile subframe comprises a box body;

As shown in FIG. 2 , it is a three-dimensional diagram of the box body of the present invention. The outer shape of the box body is a rectangular parallelepiped, so as to save floor space and facilitate handling and transportation. The top surface 1 of the box body is provided with a downwardly recessed cavity, which is designed and produced with reference to the shape structure of the automobile subframe, and its depth is adapted to the height of the subframe. The subframe includes a front subframe and a rear subframe. The present embodiment is an EPS packaging box for the rear subframe of the automobile. The cavity is a centrally symmetrical structure, and its edge contour coincides with the contour of the vertical projection of two subframes placed horizontally opposite to each other, so that it can accommodate two subframes placed horizontally opposite to each other. The cavity includes an inner side surface 2 and an inner bottom surface 3. The inner bottom surface 3 between the two sub-frames is provided with an isolation bridge 5 formed by an upward protrusion. The isolation bridge 5 isolates the two sub-frames to prevent the two sub-frames from contacting or colliding with each other and causing damage. The isolation bridge 5 and the inner side surface 2 work together to limit the sub-frames accommodated in the cavity in the horizontal direction to prevent the sub-frames from colliding with the side surfaces 2 of the box body and causing damage; the middle part of the isolation bridge 5 is disconnected to form two sections of the isolation bridge 5, and the inner bottom surface 3 between the two sections of the isolation bridge 5 is provided with a hollow material reduction port 32 to reduce material usage and reduce costs; a fixing groove 51 is respectively provided on the upper surface of the two sections of the isolation bridge 5, and the two fixing grooves 51 are symmetrically distributed with respect to the center, and a first limiting groove 52 formed by a downward depression is provided in the fixing groove 51. A plurality of support columns 31 protruding upward are symmetrically arranged on the inner bottom surfaces 3 at the proximal ends of both sides of the isolation bridge 5, and support surfaces 4 protruding upward are symmetrically arranged on the inner bottom surfaces 3 at the distal ends of both sides of the isolation bridge 5. The upper edges of the support surfaces 4 are connected to the inner side surfaces 2. The support columns 31 and the support surfaces 4 are both in contact with the sub-frame, thereby supporting and absorbing the sub-frame.

More specifically, as shown in FIG3 , it is a three-view diagram of the box body of the present invention. The top surface 1 of the box body is provided with a plurality of positioning posts 7 formed by upward protrusions, and the bottom surface of the box body is provided with a plurality of positioning grooves formed by upward depressions. The positioning posts 7 are adapted to the positioning grooves. When multiple box bodies are stacked, the positioning posts 7 of the lower box body are inserted into the positioning grooves of the upper box body to prevent the horizontal relative displacement between the upper and lower box bodies, thereby enhancing the stability of the stacking and preventing it from tipping over. The support surface 4 is provided with a plurality of reinforcing ribs 41 formed by upward protrusions. The upper edge of the reinforcing ribs 41 is connected to the top surface 1 of the box body in a sloped and smooth transition, and the side edge is connected to the inner side surface 2 of the cavity. The reinforcing ribs 41 reinforce the box body structure to reduce the material and reduce the cost. Gaps are formed on both sides of the protruding reinforcing ribs 41 to facilitate the operator to reach into the box body and take out the automobile subframe from it. The upper edge of the reinforcing ribs 41 is connected in a sloped and smooth transition to avoid the formation of sharp corners that are easily scratched and damaged.

The EPS packaging box also includes a fixing block 6 and a cover plate 8;

As shown in FIG1 , it is a three-dimensional view of the overall structure of the present invention. The lower surface of the fixed block 6 is provided with a second limiting groove 61 formed by an upward depression. The groove length of the second limiting groove 61 is adapted to the groove width of the fixed groove 51, and the groove width of the second limiting groove 61 is adapted to the groove length of the fixed groove 51, so that the fixed block 6 is fastened to the fixed groove 51, and the horizontal movement of the fixed block 6 is limited. A limiting column 62 formed by a downward protrusion is provided in the second limiting groove 61. The first limiting groove 52 is adapted to the limiting column 62, and the limiting column 62 is inserted into the first limiting groove 52. The two cooperate with each other to a certain extent to limit the longitudinal movement of the fixed block 6. When several box bodies are stacked, the bottom surface of the upper box body presses the fixed block 6 on the lower box body, further limiting the longitudinal movement of the fixed block 6. The fixed block 6 fixed on the fixed groove 51, its side wings play a role in longitudinal limiting the auxiliary frame contained in the cavity, to prevent the auxiliary frame from colliding with the bottom surface of the upper box body or even falling and being damaged. A number of cover plates 8 cover the four edges of the top surface 1. In the present embodiment, four cubic cover plates 8 cover the four straight edges of the top surface 1. The significance of this is that when a single or multiple stacked box bodies are packed and fixed, the relatively weak side walls of the box bodies are protected from damage due to the intrusion of strapping tapes due to the covering of the cover plates 8.

More specifically, as shown in FIG. 4 , which is a three-view diagram and a stereoscopic diagram of the cover plate of the present invention, a plurality of hollowed-out material reduction holes 81 are provided on the upper surface of the cover plate 8 to reduce material usage and reduce costs; the material reduction holes 81 are centrally symmetrically distributed to balance the center of gravity.

More specifically, as shown in FIG. 5 , which is a three-view diagram and a stereoscopic diagram of the fixing block of the present invention, the upper surface of the fixing block 6 is provided with a plurality of material reduction grooves 63 which are recessed downwards, so as to reduce the material usage and reduce the cost; the material reduction grooves 63 are centrally symmetrically distributed, so as to balance the center of gravity.

The EPS materials used for the box body, the fixing block 6 and the cover plate 8 are all flame-retardant EPS, which has good flame retardancy, so as to avoid accidental fire to the greatest extent.

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
