[0001] The utility model relates to a stackable logistics device for anti-collision beams, belonging to the technical field of packaging boxes. Background Art
[0002] In today's rapidly evolving automotive industry, where specialized labor is becoming increasingly specialized, auto parts are typically manufactured by dispersed auto parts manufacturers based on design drawings. These parts are then shipped to the final assembly department of the automaker for centralized assembly. Choosing the right packaging for auto parts during factory delivery, storage, transportation, and assembly can help minimize transportation losses, reduce transportation costs, and improve efficiency.
[0003] Crash beams are devices designed to absorb and mitigate collision energy during a vehicle collision. They consist of a crossbeam, energy-absorbing boxes, and connecting frames. Currently, crash beams are typically stored or transported in wooden or paper boxes, filled with flexible materials like sponge and foam to protect them from damage. However, this packaging method offers poor shock absorption and insecure anchoring, making them prone to tipping during storage and transportation due to center of gravity shifts. Furthermore, these boxes suffer from inherent drawbacks such as low packaging space utilization. Summary of the Invention

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0006] A stackable logistics device for anti-collision beams includes no less than two device bodies distributed longitudinally. The top surface of the device body is recessed inward to form a cavity for accommodating the anti-collision beam. The anti-collision beam is positively accommodated in the cavity, and the cavity is adapted to the bottom surface structure of the anti-collision beam.

[0009] Preferably, a third placement groove and / or a fourth placement groove are further provided in the mold cavity and are symmetrically distributed;
[0010] The third placement groove is adapted to the bottom surface of the energy absorption box base of the anti-collision beam, and the fourth placement groove is adapted to the bottom surface of the lower connecting frame of the anti-collision beam.
[0011] Preferably, a sixth placement groove adapted to the bottom surface of the front connecting frame of the anti-collision beam is further provided in the mold cavity.
[0012] Preferably, there are no less than two cavities and they are arranged in sequence on the top surface of the body, and the central area of the top surface of the body is recessed inward to form a hollow opening that penetrates to the bottom surface of the body of the device.
[0013] Preferably, a limiting boss is provided at the edge of the top surface of the main body and is protruded outwards, and a limiting recess is formed at the edge of the bottom surface of the main body and is matched with the limiting boss.

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.
[0033] It should be noted that in the description of the present invention, the terms "front," "rear," "left," "right," "up," "down," "inside," and "outside" and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are provided solely for the purpose of facilitating the description of the present invention and do not require that the present invention be constructed or operated in a specific direction. Therefore, they should not be construed as limiting the present invention. The terms "front," "rear," "left," "right," "up," and "down" used in the description of the present invention refer to directions in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0034] The present invention provides a stackable logistics device for use with anti-collision beams, comprising several device bodies stacked longitudinally. The top surface 1 of the device body is recessed to form a cavity for accommodating the anti-collision beam 3. The anti-collision beam 3 is positively received within the cavity, which mates with the structure of the bottom surface of the anti-collision beam 3, thereby securing the anti-collision beam 3 within the cavity. The device body is integrally molded from expanded polystyrene (EPS). EPS is a lightweight polymer formed by adding a foaming agent to polystyrene resin and heating it to soften it, generating gas. This rigid, closed-cell foam plastic exhibits low water absorption, excellent thermal insulation, light weight, and high mechanical strength. The device body, constructed from EPS, exhibits excellent shock-absorbing properties, preventing damage to the anti-collision beam 3 caused by bumps or impacts during storage and transportation. The integral molding of the device body also provides excellent structural strength.
[0035] like Figures 6 to 8 As shown, they are respectively the front structural diagram, the back structural diagram and the side view of the anti-collision beam in the embodiment of the present invention. The anti-collision beam 3 is composed of a middle section 31 of the beam, a bent section 36 of the beam and an end section 32 of the beam. A front connecting frame 311 is provided on the front side of the middle section 31 of the beam, and an upper connecting frame 312 is provided on the upper side of the middle section 31 of the beam. An energy absorption box 33 is welded on the side between the bent section 36 of the beam and the end section 32 of the beam, and a lower connecting frame 35 is provided on the lower side of the welding point between the beam and the energy absorption box 33. The energy absorption box 33 is connected to the vehicle body via the energy absorption box base 34. The energy absorption box 33 plays the role of crushing and absorbing energy when subjected to a frontal impact, so its axial strength is not very high. If it is subjected to axial force for a long time, it may cause the energy absorption box 33 to crush and deform. Therefore, the present invention adopts a receiving posture in which the anti-collision beam 3 is placed in a forward direction, and the bottom surface of the energy absorption box 33 is in contact with the cavity, thereby avoiding axial force deformation of the energy absorption box 33.
[0036] like Figures 1 to 5The figures show, respectively, the top perspective view, top view, bottom perspective view, bottom view, and front view of the device body according to an embodiment of the present invention. A first placement slot 12, a second placement slot 13, and a fifth placement slot 16 are symmetrically arranged within the mold cavity. The first placement slot 12 mates with the bottom surface of the beam end 32, the second placement slot 13 mates with the bottom surface of the energy absorption box 33, and the fifth placement slot 16 mates with the bottom surface of the beam bend 36. The first placement slot 12, the second placement slot 13, and the fifth placement slot 16 respectively support the bottom surfaces of the beam end 32, the energy absorption box 33, and the beam bend 36, thereby evenly supporting the weight of the anti-collision beam 3.
[0037] The mold cavity also includes a third placement slot 14 and a fourth placement slot 15, which are symmetrically distributed. The third placement slot 14 matches the bottom surface of the energy absorption box base 34, and the fourth placement slot 15 matches the bottom surface of the lower connecting frame 35. The mold cavity also includes a sixth placement slot 18, which matches the bottom surface of the front connecting frame 311. The third placement slot 14, the fourth placement slot 15, and the sixth placement slot 18 respectively accommodate the energy absorption box base 34, the lower connecting frame 35, and the front connecting frame 311, but do not directly bear the weight. This is because the lower connecting frame 35 and the front connecting frame 311 lack load-bearing structure and strength; while the energy absorption box base 34 is heavy but has a small bottom area, resulting in a high pressure per unit area, which can easily damage the mold cavity structure, thereby affecting the service life of the logistics device of this utility model.
[0038] There are at least two cavities, arranged sequentially on the top surface 1 of the main body. This means that the anti-collision beams 3 housed in each cavity are oriented in the same direction. This technical measure helps improve lateral packaging space utilization, accommodating a greater number of anti-collision beams 3 within a limited lateral space. In this embodiment, each device body is provided with five cavities, each accommodating five corresponding anti-collision beams 3. As a preferred embodiment, the central area of the main body top surface 1 is recessed to form a hollow opening 17 extending through the bottom surface 2 of the device body. This technical measure saves material and weight without compromising the structural strength of the device body, and simplifies the cavity structure.
[0039] To enable stacking of multiple appliance bodies and improve packaging space utilization in the vertical direction, the top edge of the body 1 is provided with an outwardly protruding limiting boss 11. The bottom edge 2 of the body is recessed inwardly to form a limiting recess 21 that mates with the limiting boss 11. Both limiting bosses 11 and 21 are annular in design. When multiple appliance bodies are stacked, the limiting boss 11 of the lower layer fits neatly into the limiting recess 21 of the upper layer, thereby lateral limiting and securing adjacent appliance bodies.
[0040] As a preferred solution, the limiting boss 11 is provided with a uniform weight concave platform 111 formed by an inward depression, and the limiting concave platform 21 is convex outward to form a uniform weight boss 211 adapted to the uniform weight concave platform 111. When multiple appliance bodies are stacked, the orientation of the adjacent appliance bodies is rotated 180 degrees in the horizontal direction. Figure 11 The figure shows the orientation of adjacent device bodies when stacked. When stacked in this relative orientation, the uniformly weighted projections 211 of the upper device body fit neatly into the uniformly weighted recesses 111 of the lower device body. The significance of this technical measure lies in that when multiple device bodies housing anti-collision beams 3 are stacked, adjacent device bodies can only be stacked in an orientation rotated 180 degrees relative to each other, rather than in the same orientation. This ensures that the center of gravity of the logistics device of this utility model is centered, preventing tipping due to a shift in the center of gravity.
[0041] As a preferred solution, the bottom surface 2 of the main body is recessed inward to form a clearance groove 22 that mates with the top surface of the energy absorption box base 34 of the anti-collision beam 3. When multiple appliance bodies are stacked, the top surface of the energy absorption box base 34 of the anti-collision beam 3 in the lower appliance body can be accommodated within the clearance groove 22 of the upper appliance body. This technical measure helps reduce the height of the appliance bodies, allowing more appliance bodies to be stacked within a limited longitudinal space, accommodating more anti-collision beams 3.
[0042] 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.
