Detailed Description

The utility model is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

It should be noted that in the description of the present invention, the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention but do not require that the present invention must be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 8, which is a schematic structural diagram of the rear axle of the automobile in the embodiment of the present invention, the rear axle includes a main axle pipe 91 and a curved pipe 93 connected to two ends of the main axle pipe 91, a pipe body support 92 is disposed on the main axle pipe 91, the curved pipe 93 is connected to an end support 96 and a damper connection end 97 through a coupling plate 95, and an end of the curved pipe 93 is connected to a lower control arm connection end 94. The curved structure of the curved tube 93, as well as the significantly convex and irregularly shaped tube body bracket 92 and end bracket 96, is a major cause of poor packaging efficiency of the rear axle 9 of the automobile.

The utility model provides a packing box for an automobile rear axle, which is integrally formed and manufactured by adopting Expanded Polystyrene (EPS). EPS is a light high molecular polymer, which is a foamed plastic with a hard closed-cell structure formed by adding a foaming agent into polystyrene resin and softening the polystyrene resin by heating, and has the characteristics of low water absorption, good heat insulation, light weight, higher mechanical strength and the like.

As shown in fig. 1 to 5, which are an upper view, a front view, a left view, a top view and a lower view of the overall structure of the embodiment of the present invention, a cavity for horizontally accommodating the rear axle 9 is formed in the top surface 1 of the packing box, the cavity can be divided into an upper layer and a lower layer for accommodating four rear axles 9, and can also be used for accommodating more layers of rear axles 9 or more numbers of rear axles 9 as required.

To achieve the purpose, the design is as follows: be equipped with two front and back parallel distribution's vertical support board 3 in the die cavity, vertical support board 3's top surface is inwards sunken to be formed with first pipe shaft and supports groove 31 and second pipe shaft and support groove 32, and wherein the groove face height that first pipe shaft supported groove 31 is showing and is being less than second pipe shaft and supports groove 32, and first pipe shaft supports groove 31 and is used for supporting lower floor's car rear axle 9's main shaft pipe 91, and second pipe shaft supports groove 32 and is used for supporting upper automobile rear axle 9's main shaft pipe 91. An end supporting groove 4 is formed in the predetermined region of the cavity in an inward concave manner, and an end supporting platform 5 is formed in an outward convex manner, wherein the end supporting groove 4 is used for supporting a lower control arm connecting end 94 of the lower layer automobile rear axle 9, and the end supporting platform 5 is used for supporting a lower control arm connecting end 94 of the upper layer automobile rear axle 9. The cavity defined region is also inwards sunken to form an end bracket containing groove 6 for containing an end bracket 96 of the lower automobile rear axle 9. The area between the two vertical supporting plates 3 in the cavity is formed into a pipe body support accommodating groove 7 for accommodating a pipe body support 92 of a lower-layer automobile rear shaft 9. Of course, a design of only accommodating one layer of the rear axle 9 of the automobile can be adopted, and at the moment, only the first pipe body supporting groove 31 or the second pipe body supporting groove 32 is arranged on the vertical supporting plate 3, so that the height of the packing box can be reduced, but the space utilization rate is different from that of the two-layer design. Similarly, the two vertical supporting plates 3 can also be designed in a non-parallel manner, such as an opposite inclined manner, and are symmetrically distributed in the horizontal direction, but the design has a support performance inferior to the aforementioned parallel design, and is not favorable for forming the space required by the tube body support accommodating groove 7.

As shown in fig. 6 and 7, the two and four rear axles of the vehicle according to the embodiment of the present invention are respectively illustrated. As can be seen from the figure, in order to further reduce the overall dimension of the packing box, the side surface 2 of the packing box is hollowed to form a first air isolating opening 21 and a second air isolating opening 22, wherein the first air isolating opening 21 is used for accommodating a lower control arm connecting end 94 on the outer side of the lower layer automobile rear axle 9, and the second air isolating opening 22 is used for accommodating a lower control arm connecting end 94 on the outer side of the upper layer automobile rear axle 9.

In this embodiment, in order to increase the contact area between the packing box and the rear axle 9 of the automobile and reduce the pressure on the packing box, the first tube body supporting groove 31 and the second tube body supporting groove 32 are both designed to have arc surfaces adapted to the main axle tube 91. For enhancing the shock absorbing performance, the end support groove 4 and the end support table 5 for supporting the lower control arm connecting end 94 are recessed inward to form the buffer groove 41, and when being impacted in the vertical direction, the end support groove 4 and the end support table 5 can extend radially toward the buffer groove 41 to be slightly deformed in the vertical direction to protect the rear axle 9 of the automobile from being damaged by shock. In order to improve the structural strength of the packaging box, the side surface 2 of the packaging box and the side surface 23 of the cavity are both bulged outwards to form reinforcing columns 24 which are vertically and continuously distributed. For the space area that practices thrift the packing box and occupy, packing box top surface 1 is inwards sunken to be formed with

spacing groove

11, and 8 outside archs in packing box bottom surface are formed with the spacing platform 81 with 11 looks adaptations of spacing groove, and when a plurality of packing box stacks were placed, spacing platform 81 embedding of upper strata packing box can realize spacing and fixed function to the spacing groove 11 and the die cavity mouth department of lower floor's packing box. In order to save materials, the bottom surface 8 of the packing box and the limiting table 81 are both inwards sunken to form a material reducing groove 82.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
