[0002] Today, with the rapid and refined development of the division of labor in the automotive industry, automotive parts are usually manufactured by automotive parts manufacturers scattered in different regions according to design drawings, and then transported to the general assembly department of the vehicle enterprise for unified assembly. In the process of the factory production, storage, transportation and assembly of automotive parts, scientifically selecting the packaging box for automotive parts is beneficial to minimizing transportation losses, reducing transportation costs and improving transportation efficiency to the greatest extent.

[0003] The front panel of an automobile refers to the structural member between the engine compartment and the carriage. It is connected to the floor and the front pillar and is installed under the upper cover plate of the front panel. There are many orifices on the front panel structural member for the passage of operating wires, rods, pipelines and wire harnesses, and it also needs to cooperate with the installation positions of parts such as pedals and steering columns. The upper part of the front panel is the upper structure of the front panel of the automobile, which is heavy and has an irregular external shape, resulting in difficulty in fixing during storage and transportation. When multiple upper parts of the front panel are packaged together, in order to avoid rubbing against each other, it is usually necessary to fill flexible materials such as sponges and foams for buffering and auxiliary fixing. The upper parts of the front panel are arranged loosely, with poor compactness and low utilization rate of the packaging space. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a compact packaging box for the upper part of the front panel, aiming to solve the technical problems of poor fixing, poor compactness and low utilization rate of the packaging space in the prior art for the upper part of the front panel.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A compact packaging box for the upper part of the front panel includes at least two packaging box bodies stacked longitudinally. The top surface of the packaging box body is recessed inward to form a cavity for receiving the upper part of the front panel.

[0012] Preferably, a hollow opening penetrating the bottom surface of the packaging box body is formed by inward depression on the top surface or / and the bottom surface of the cavity of the packaging box body;

[0013] The hollow opening runs across the middle section of each first cavity and the second cavity, dividing the water baffle support groove into two sections on the left and right, and dividing the support seat into a first support seat and a second support seat.

[0014] Preferably, a first pressing surface is formed by inward depression on the non-edge area of the top surface of the packaging box body, and the cavity is formed on the first pressing surface;

[0015] A limit boss is formed on the non-inwardly depressed edge area of the top surface of the packaging box body, and a limit concave groove adapted to the limit boss is formed by inward depression on the edge area of the bottom surface of the packaging box body.

[0016] Preferably, an observation opening is formed by inward depression on the limit boss and the first pressing surface, and the cavity is communicated with the side surface of the packaging box body through the observation opening.

[0017] Preferably, a material reduction groove or / and a second avoidance groove is formed by inward depression on the bottom surface of the packaging box body;

[0018] When multiple packaging box bodies are stacked longitudinally, the part of the upper front panel received in the lower packaging box body that exceeds the first pressing surface is received in the second avoidance groove of the upper packaging box body.

[0019] Preferably, a storage groove is further formed by inward depression on the first pressing surface.

[0036] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and cannot be used to limit the protection scope of the present invention.

[0037] It should be noted that in the description of the present invention, the orientation or positional relationship indicated by the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present invention. The terms "front", "rear", "left", "right", "upper", "lower" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0038] The specific embodiment of the present invention provides a compact packaging box for the upper front panel, which is formed by stacking and combining a plurality of packaging box bodies longitudinally. The packaging box body is integrally formed with expanded polystyrene (EPS). EPS is a light polymer. It is made by adding a foaming agent to polystyrene resin and heating it to soften it, generating gas, and forming a rigid closed-cell structure foam plastic, which has the characteristics of small water absorption, good heat preservation, light weight and relatively high mechanical strength.

[0039] The specific structure of the upper front panel 3 is as Figures 5 to 7As shown in the figure, it includes a front windshield lower cross member 33 and a ventilation cover plate 34 that are bent and connected to each other, and side wall panels 31 connected to the left and right sides of the engine compartment are provided at both ends. A ventilation opening 331 is provided on the front windshield lower cross member 33, and a ventilation guide plate 332 that protrudes outward is formed on the front surface of the front windshield lower cross member 33. The ventilation guide plate 332 is suspended above the ventilation opening 331. A water baffle 32 is connected to the rear end of the front windshield lower cross member 33. A number of outwardly protruding limit pins 35 are provided on the back surfaces of the front windshield lower cross member 33 and the ventilation cover plate 34. It can be seen from the figure that the overall front surface of the upper part of the front panel 3 is concave, the concave angle formed by the front windshield lower cross member 33 and the ventilation cover plate 34 is about 90 degrees, and the ventilation guide plate 332 protrudes relatively; the back surface of the upper part of the front panel 3 is convex, and there are many limit pins 35 that are prone to damage; the side wall panels 31 at both ends of the upper part of the front panel 3 extend radially outward.

[0040] The specific structure of the packaging box body is as Figures 1 to 4 shown. Its top surface is recessed inward to form a number of cavities for receiving the upper part of the front panel 3, including at least two first cavities symmetrically distributed along the transverse direction and a second cavity provided between two adjacent first cavities. The back surface of the upper part of the front panel 3 received in the first cavity faces downward, and the specific receiving posture is as Figures 8 to 10 shown; the front surface of the upper part of the front panel 3 received in the second cavity faces downward, and the specific receiving posture is as Figures 11 to 13 shown, that is, the posture of the middle upper part of the front panel 3.

[0041] More specifically, a side wall panel support groove 12, a water baffle support groove 13, and a ventilation cover plate support groove 14 are provided in the first cavity. Among them, the side wall panel support groove 12 is adapted to the side wall panel 31 and is symmetrically distributed along the transverse direction, and is used to accommodate the radially extended side wall panel 31 of the upper part of the front panel 3 to avoid extrusion force, and at the same time also plays a certain supporting role to prevent the upper part of the front panel 3 from deforming due to long-term suspension at both ends. The water baffle support groove 13 is adapted to the back surface of the water baffle 32 of the upper part of the front panel 3 and supports the water baffle 32. The ventilation cover plate support groove 14 is adapted to the back surface of the ventilation cover plate 34 of the upper part of the front panel 3 and also supports the ventilation cover plate 34.

[0042] As a preferred solution, the bottom surfaces of the water baffle support groove 13 and the ventilation cover plate support groove 14 are recessed inward to form a first avoidance groove 141 adapted to the limit pins 35 on the back surface of the upper part of the front panel 3. The limit pins 35 are accommodated in the first avoidance groove 141 in an avoidance manner, so as to avoid damage caused by pressure. In this embodiment, the ventilation cover plate support grooves 14 of the two first cavities face outward, and the ventilation cover plates 34 of the received upper parts of the front panel 3 face the side surfaces of the first cavities. At this time, the ventilation cover plates 34 are close to perpendicular to the bottom surface of the cavity, so as to laterally limit the packaging space occupied by the upper part of the front panel 3. The side surface of the first cavity is recessed inward to form a first avoidance groove 141 adapted to the limit pins 35, and the limit pins 35 on the back surface of the ventilation cover plate 34 are accommodated in the first avoidance groove 141 in an avoidance manner, so as to avoid damage caused by pressure.

[0043] More specifically, a side wall support groove 12 and a support seat are provided in the second cavity. The function of the side wall support groove 12 is the same as that of the side wall support groove 12 on the inner side of the first cavity. The support seat is adapted to the front surface of the lower cross beam 33 of the front windshield of the upper part 3 of the front panel, and plays a role in supporting the front surface of the lower cross beam 33 of the front windshield. Since the front surface of the upper part 3 of the front panel is integrally concave, with the combined support of the side wall support groove 12 and the support seat, a good limiting effect can be exerted on the upper part 3 of the front panel. The upper part 3 of the front panel placed face-down in the second cavity fits with the upper parts 3 of the front panel placed back-down in the front and back, and can further limit the packaging space it occupies in the transverse direction, specifically as Figures 11 to 13 shown.

[0044] More specifically, a first pressing surface 11 is formed by inward depression of the non-edge area of the top surface of the packaging box body. The cavity is formed on the first pressing surface 11. A limiting boss 1 is formed on the edge area of the top surface of the packaging box body that does not inwardly sink. A limiting concave groove 2 adapted to the limiting boss 1 is formed by inward depression of the edge area of the bottom surface of the packaging box body. A second pressing surface 21 is formed on the non-edge area of the bottom surface of the packaging box body that does not inwardly sink. When multiple packaging box bodies are stacked longitudinally, the second pressing surface 21 of the upper packaging box body just presses on the first pressing surface 11 of the lower packaging box body, and the limiting concave groove 2 of the upper packaging box body just presses on the limiting boss 1 of the lower packaging box body, so as to realize the transverse limiting of adjacent packaging box bodies and avoid tipping during storage and transportation. In this embodiment, a plurality of storage grooves 19 are further formed by inward depression of the first pressing surface 11, which can be used to place the accessories of the upper part 3 of the front panel to avoid loss during separate storage and transportation.

[0045] As a preferred solution, a material reduction groove 22 and a second avoidance groove 23 are formed by inward depression of the bottom surface of the packaging box body. The material reduction groove 22 mainly plays a role in weight reduction and material saving. When multiple packaging box bodies are stacked longitudinally, the part of the upper part 3 of the front panel received in the lower packaging box body that exceeds the first pressing surface 11 is received in the second avoidance groove 23 of the upper packaging box body. This technical measure is beneficial to reducing the height of the packaging box body and improving the utilization rate of the packaging space in the longitudinal direction.

[0046] As a preferred solution, a hollow opening 17 penetrating through the bottom surface of the packaging box body is formed by the inward depression of the top surface of the packaging box body and the bottom surface of the cavity, which plays a role in material saving and weight reduction. At the same time, it also plays a role in accommodating the part of the upper front panel 3 exceeding the first pressing surface 11 contained in the lower packaging box body. The hollow opening 17 runs across the middle section of each first cavity and the second cavity, divides the water baffle support groove 13 into two sections on the left and right, and divides the support seat into a first support seat 15 and a second support seat 16. Among them, the first support seat 15 is higher than the second support seat 16 because the second support seat 16 needs to avoid the ventilation and diversion plate 332 with a significant protrusion on the front surface of the lower cross beam 33 of the front windshield.

[0047] As a preferred solution, a viewing port 18 is formed by the inward depression of the limiting boss 1 and the first pressing surface 11, and the cavity is connected to the side surface of the packaging box body through the viewing port 18. When multiple packaging box bodies are stacked longitudinally, the operator can observe the situation of the upper front panel 3 contained in the packaging box body through the viewing port 18 of the lower packaging box body, and can also easily lift the upper packaging box body through the viewing port 18 for handling operations.

[0048] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
