Description

Technical Field

[0001] The invention relates to a logistics device used for a front auxiliary frame, 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] The front subframe of an automobile is developed based on the modularization and platformization of the automobile chassis. It can withstand the vibration load of the engine mount and various impacts from the road surface, reduce the vibration and noise caused by the road surface and the engine, and ensure driving comfort and stability. The front subframe is provided with a front subframe body with a plurality of protrusions. The front subframe body extends laterally to form four significantly protruding lower connecting plates, and extends longitudinally upward to form an upper connecting plate, which also protrudes laterally outward. Due to the irregular overall shape of the front subframe of an automobile, the utilization rate of the packaging space is low during its packaging, storage and transportation, which is not conducive to improving packaging quality and enhancing logistics efficiency. Currently, when storing or transporting the front subframe, it is usually placed in a wooden or paper packaging box and filled with flexible materials such as sponge and foam to prevent it from being damaged. This packaging method has many defects such as poor shock absorption, loose fixation, and easy contamination. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a logistics device for the front subframe to solve the technical problems of low packaging space utilization, loose fixation, and easy contamination of the packaging box of the front subframe of the automobile in the existing technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A logistics device for a front sub-frame comprises at least two longitudinally distributed device bodies. The top surfaces of the device bodies are provided with an inwardly recessed cavity, and the front sub-frame is accommodated in the cavity.

[0007] Preferably, the front sub-frame is positively received in the cavity, and the cavity surface of the cavity is adapted to the bottom surface of the front sub-frame;

[0009] Preferably, the other front sub-frame is received in the cavity in an inverted manner;

[0010] The top surface of the body is further provided with a second supporting surface and / or a third supporting surface formed inwardly concave, the second supporting surface supports the upper connecting plate of the other front sub-frame, and the third supporting surface supports the lower connecting plate of the other front sub-frame.

[0011] Preferably, the front sub-frame and the other front sub-frame are placed in a staggered direction with respect to each other.

[0012] Preferably, the top surface of the main body is provided with a concave platform formed inwardly, and the bottom surface of the main body of the device body is convex outwardly to form a convex platform corresponding to the concave platform;

[0013] At least any one of the mold cavity, the first supporting surface, the second supporting surface, and the third supporting surface is formed on the concave platform.

[0014] Preferably, the top surface of the body is provided with a first groove formed inwardly concave, or / and the bottom surface of the body of the utensil body is provided with a third groove formed inwardly concave;

[0015] The mold cavity is communicated with the side surface of the device body via the first groove, and the third groove is communicated with the side surface of the device body and is symmetrically distributed.

[0016] Preferably, the bottom surface of the appliance body is provided with a material reduction groove formed by an inward depression.

[0017] Preferably, a second groove is provided on the bottom surface of the body and is recessed inwards, and the material reduction groove is connected with the side surface of the device body via the second groove.

[0018] Preferably, there are no less than two cavities, and partitions are formed between adjacent cavities.

[0019] Preferably, the device body is made of EPS material and / or is integrally formed.

[0020] Compared with the prior art, the present invention achieves the following beneficial effects: it includes at least two longitudinally distributed device bodies, the top surface of the body being provided with an inwardly recessed cavity, the cavity surface of the cavity being adapted to the bottom surface of the front subframe, and the top surface of the body being provided with a first support surface, a second support surface, and a third support surface, each of which is formed as an inward recess.

[0033] 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 solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0034] 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. These are intended solely to facilitate the description of the present invention and do not require that the present invention be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on 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.

[0035] A specific embodiment of the present invention provides a logistics device for a front subframe, comprising several device bodies stacked longitudinally. The device bodies are 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 creates a rigid, closed-cell foam plastic with low water absorption, excellent thermal insulation, light weight, and high mechanical strength.

[0036] like Figure 7 and Figure 8 The figures show, respectively, top and bottom perspective views of a front subframe according to an embodiment of the present invention. The front subframe 3 comprises a front subframe body 31, which extends laterally outward to form four lower connecting plates 32. The top surface of the front subframe body 31 is provided with two upper connecting plates 33, which extend longitudinally and then laterally. The top surface of the front subframe body 31 also includes several protrusions 34. As can be seen from the figures, the top surface of the front subframe 3 is a complex structure, being not only uneven but also having numerous longitudinal protrusions. The bottom surface of the front subframe 3 is relatively flat, making it easier to bear weight and stress.

[0037] like Figures 1 to 6 The figures are respectively the top perspective view, bottom perspective view, top view, bottom view, front view, and left view of the apparatus body according to an embodiment of the present invention. The top surface 1 of the apparatus body is provided with an inwardly recessed concave platform 11, and the bottom surface 2 of the apparatus body is provided with an outwardly protruding platform 21. The concave platform 11 and the protrusion 21 correspond to each other in shape and structure. When multiple apparatus bodies are stacked, the protrusion 21 of the upper apparatus body fits neatly into the concave platform of the lower apparatus body, thereby achieving lateral positioning between adjacent apparatus bodies and preventing them from tipping over.

[0038] The recessed platform 11 is provided with an inwardly recessed cavity and a first support surface 14. The bottom surface of the front subframe 3 is received in the cavity in a downwardly facing position. The cavity surface of the cavity matches the bottom surface of the front subframe 3 and is used to support the front subframe body 31 and the lower connecting plate 32 of the front subframe 3. The cavity structure provides full contact, balanced load-bearing, and lateral positioning. When multiple device bodies are stacked, the upper device body also acts as a longitudinal limiter for the front subframe 3 received in the lower device body, thereby firmly securing the front subframe 3. Two first support surfaces 14 are provided, corresponding to the height and shape of the upper connecting plate 33 of the front subframe 3. They are used to support the upper connecting plate 33, share the load, and prevent the weight of the front subframe 3 from being concentrated on the cavity surface, which is beneficial to improving the durability of the device body.

[0039] The recessed platform 11 also has a second support surface 15 and a third support surface 16 formed inwardly, with each cavity correspondingly provided with two second support surfaces 15 and four third support surfaces 16. The other front subframe 3 is received in the cavity in an inverted position with its bottom surface facing upward. The second support surface 15 corresponds to the height and shape of the two upper connecting plates 33 of the front subframe 3, and is used to support the upper connecting plates 33. The third support surface 16 corresponds to the height and shape of the four lower connecting plates 32 of the front subframe 3, and is used to support the lower connecting plates 32. The two front subframes 3 are placed opposite each other in the cavity, and their orientations are staggered. This has at least three effects: first, it significantly compresses the longitudinal space occupied by the two front subframes 3, which helps improve packaging space utilization; second, it prevents the protrusions 34 on the front subframes 3 from directly contacting the device body, preventing damage during storage and transportation; and third, it ensures that the center of gravity does not shift, preventing tipping during stacking.

[0040] In this embodiment, each device body is provided with two cavities, and each cavity accommodates two front sub-frames 3 placed opposite each other and staggered with each other. The two cavities can accommodate four front sub-frames 3. Compared with the traditional packaging method, the number of accommodated front sub-frames 3 is significantly increased, and the utilization rate of the packaging space is significantly improved. A partition 17 is formed between the two cavities, which mainly plays an isolation role and avoids collisions between two adjacent front sub-frames 3 in the horizontal direction. The order of accommodating the front sub-frames 3 in the device body is: first, the two front sub-frames 3 placed in the same direction are accommodated in the two cavities, as shown in the following figure. Figure 9 Then, the other two inverted front subframes 3 are staggered and accommodated in the two cavities, as shown in FIG. Figure 10 and Figure 11 shown.

[0041] Preferably, the top surface 1 of the main body is provided with a first, inwardly recessed groove 12, and the bottom surface 2 is provided with a second, inwardly recessed groove 22, a third, and a material-reducing groove 24. The mold cavity communicates with the side of the tool body via the first groove 12, allowing the operator to reach into the cavity through the first groove 12 and smoothly remove the front subframe 3 from the cavity. Several material-reducing grooves 24 are provided, primarily to save material and reduce weight. The material-reducing groove 24 near the outer edge of the bottom surface 2 communicates with the side of the tool body via the second groove 22, allowing the operator to reach into the material-reducing groove 24 through the second groove 22, thereby saving effort and making it easier to lift the tool body. The third grooves 23 communicate with the side of the tool body and are horizontally symmetrically distributed. Their function is to allow the strapping to be tied together via the symmetrically distributed third grooves 23 after multiple tool bodies are stacked. The third grooves 23 secure the strapping position and prevent it from slipping.

[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.
