Description

Technical Field

[0001] The present invention relates to a logistics appliance for a rear axle and its packaging method, belonging to the technical field of packaging boxes. Background Art

[0002] Today, with the rapid development of the refined 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. During the processes of the production, storage, transportation, and assembly of automotive parts, scientifically selecting the packaging boxes for automotive parts is conducive to minimizing transportation losses, reducing transportation costs, and improving transportation efficiency.

[0003] The rear axle of an automobile is connected to the vehicle frame through a suspension, and wheels are installed at both ends. The function of the rear axle is to bear the load of the automobile and maintain the normal driving of the automobile on the road. The rear axle can be integral, like a huge barbell, with both ends supporting the vehicle body through a suspension system; the rear axle can also be a disconnected type, like two umbrellas inserted on both sides of the vehicle body, and then each supports the vehicle body through a suspension system, so the disconnected rear axle is used in combination with an independent suspension. Due to the special-shaped structure of the rear axle, the utilization rate of the packaging space is low during storage and transportation. Currently, when storing or transporting the rear axle, it is usually placed in a wooden or paper packaging box, and flexible materials such as sponge and foam are filled to avoid damage. This packaging method not only has defects such as poor shock absorption, insecure fixation, and easy pollution, especially it is difficult to balance its own strength and weight at the same time, which is not conducive to improving the packaging quality and enhancing the logistics efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a logistics appliance for a rear axle and its packaging method to solve the technical problems of low space utilization rate, poor shock absorption, and insecure fixation in the existing packaging method of automotive rear axles.

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

[0013] The cavity further includes a second connecting plate groove formed by inward depression from the top surface of the body and communicating with the rear axle body groove. The second connecting plate groove is adapted to the suspension connecting plate of the rear axle;

[0014] The second concave platform and the second connecting plate groove support the end assembly of the other rear axle, and the rear axle body groove houses the rear axle body of the other rear axle.

[0015] Preferably, the two rear axles housed in the cavity are placed oppositely in the vertical direction.

[0016] Preferably, the receiving block includes a support column. A first concave platform is formed by inward depression from the bottom surface of the support column. The receiving block is pressed on the end assembly of the rear axle via the first concave platform;

[0017] The second concave platform is formed by inward depression from the top surface of the support column.

[0018] Preferably, a clamping block is formed by outward protrusion on the side surface of the support column, and a clamping groove adapted to the clamping block is formed by inward depression on the side surface of the end groove;

[0019] The receiving block is clamped to the clamping groove of the appliance body via the clamping block.

[0020] Preferably, there are no less than two appliance bodies and they are longitudinally distributed;

[0021] A limiting column is formed by outward protrusion on the top surface of the body, and a limiting groove adapted to the limiting column is formed by inward depression on the bottom surface of the appliance body.

[0022] Preferably, a material-saving groove is formed by inward depression on the bottom surface of the body, and the limiting groove is included in the material-saving groove.

[0023] To achieve the above object, the present invention also provides a packaging method for a logistics appliance for a rear axle. This method is implemented based on the aforementioned logistics appliance of the invention and includes the following steps:

[0047] 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.

[0048] It should be noted that in the description of the present invention, the orientation or positional relationship indicated by terms such as "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and does not require the present invention to be constructed and operated in a specific orientation. Therefore, it should not be construed 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 drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0049] The specific embodiment of the present invention provides a logistics appliance for a rear axle, which is composed of a plurality of appliance bodies 1 stacked longitudinally, and each appliance body 1 is provided with a corresponding receiving block 2. As Figure 1 shown, it is a top perspective view of the appliance body in the embodiment of the present invention. This figure includes the appliance body 1 and the corresponding receiving block 2. The appliance body 1 is integrally formed by using expanded polystyrene (EPS). EPS is a lightweight polymer. It is made by adding a foaming agent to polystyrene resin and heating it to soften it simultaneously to generate gas, forming a rigid closed-cell structure foam plastic, which has characteristics such as small water absorption, good heat preservation, good shock absorption, light weight, and relatively high mechanical strength. The receiving block 2 is also integrally formed and can be made of EPS material, or can be made of other materials with higher strength according to needs to meet its load-bearing and supporting requirements.

[0050] As Figure 9 and Figure 10 shown, they are respectively the top and bottom perspective views of the automotive rear axle in the embodiment of the present invention. The rear axle 5 includes a rear axle body 51, and end components are symmetrically arranged at both the left and right ends of the rear axle body 51. The end components include a suspension connecting plate 52, a first connecting arm 53, and a second connecting arm 54. The rear axle 5 installs the suspension via the suspension connecting plate 52, and installs the wheels and the subframe via the first connecting arm 53 and the second connecting arm 54. It can be seen from the figures that the end components are of special-shaped structures, so the utilization rate of the packaging space is low during storage and transportation.

[0051] As Figure 2 shown, it is a top view of the appliance body without the receiving block in the embodiment of the present invention. The top surface 3 of the body of the appliance body 1 is recessed inward to form two cavities for receiving the rear axle 5. The shape of each cavity is basically adapted to the contour of the rear axle 5 in the receiving posture, that is, one rear axle 5 can be received in each cavity, and the cavity plays a role of laterally limiting and fixing the received rear axle 5.

[0052] The cavity includes a rear axle body groove 33, a first connecting plate groove 34, a first connecting arm groove 35, and a second connecting arm groove 36 that are recessed inward from the top surface 3 of the body. Among them, the rear axle body groove 33 is adapted to the rear axle body 51 of the rear axle 5 and is used to accommodate the rear axle body 51. The first connecting plate groove 34, the first connecting arm groove 35, and the second connecting arm groove 36 are collectively referred to as end grooves, which are symmetrically arranged at the left and right ends of the rear axle body groove 33 and are adapted to the end components at both ends of the aforementioned rear axle body 51, playing a role in accommodating and fixing the end components. Specifically: The first connecting plate groove 34 is adapted to the suspension connecting plate 52 of the rear axle 5 and is used to accommodate the suspension connecting plate 52; the first connecting arm groove 35 is adapted to the first connecting arm 53 of the rear axle 5 and is used to accommodate the first connecting arm 53; the second connecting arm groove 36 is adapted to the second connecting arm 54 of the rear axle 5 and is used to accommodate the second connecting arm 54.

[0053] A number of limiting posts 31 are formed by protruding outward on the top surface 3 of the body, and a limiting groove adapted to the limiting posts 31 is recessed inward on the bottom surface 4 of the body of the appliance body 1. When a plurality of appliance bodies 1 are stacked, the limiting posts 31 of the lower appliance body 1 just fit into the limiting grooves of the upper appliance body 1, playing a role of lateral limiting and fixing for two adjacent appliance bodies 1 and preventing them from tipping over during storage and transportation. The upper appliance body 1 also plays a role of longitudinal limiting for the rear axle 5 accommodated in the lower appliance body 1, thereby firmly fixing the rear axle 5 in the cavity.

[0054] As Figures 3 to 6 shown, they are respectively the bottom three-dimensional view, bottom view, front view, and left view of the appliance body in the embodiment of the present invention. A material-saving groove 41 is recessed inward on the bottom surface 4 of the body, playing a role of weight reduction and material saving. The middle section of the rear axle body groove 33 and the adjacent top surface 3 of the body are hollowed out inward to form a material-saving opening 38, which penetrates to the bottom surface 4 of the body, also playing a role of weight reduction and material saving, and at the same time facilitating the operator to observe the state of the accommodated items inward through the material-saving opening 38. The aforementioned limiting groove is included in the edge of the material-saving groove 41, that is, the edge of the material-saving groove 41 fits the limiting posts 31 of the lower appliance body 1. This design is beneficial to simplifying the structure of the appliance body 1, improving the yield rate, and reducing the manufacturing cost.

[0055] A lifting groove 42 that communicates with the side surface of the appliance body 1 is recessed inward on the top surface 3 or / and the bottom surface 4 of the body, facilitating the operator to carry the appliance body 1 through the lifting groove 42. The lifting groove 42 on the top surface 3 of the body communicates with the cavity, and also facilitates the operator to observe the state of the accommodated items inward through the lifting groove 42.

[0056] The bottom surface 4 of the main body is recessed inward to form a packing groove 43 communicating with the side surface of the appliance main body 1. When multiple appliance main bodies 1 are stacked, it is usually necessary to bundle the appliance main bodies 1 with a packing belt to prevent them from scattering during transportation. The packing groove 43 plays a role in limiting the packing belt and preventing it from slipping.

[0057] As Figure 7 and Figure 8 shown, are the perspective view and top view of the receiving block in the embodiment of the present invention. The receiving block 2 includes a support column 22 with a vertical axis, and the support column 22 is a hollow structure, which is convenient for saving materials and reducing weight. A clamping block 21 is formed by protruding outward on the right side surface of the support column 22. A first concave platform 23 is recessed inward on the bottom surface of the support column 22 to the left, and a second concave platform 24 is recessed inward on the top surface of the support column 22 to the left. A clamping groove 32 adapted to the clamping block 21 is recessed inward on the side surface of the end groove of the appliance main body 1. The receiving block 2 is clamped in the clamping groove 32 of the appliance main body 1 through the clamping block 21, and they are a firm mortise and tenon structure and are not likely to fall off.

[0058] After the receiving block 2 is installed, the receiving block 2 just presses on the end assembly of the rear axle 5 through the first concave platform 23. In this embodiment, the first concave platform 23 presses on the suspension connecting plate 52 of the rear axle 5. At the same time, the receiving block 2 presses on the bottom surface of the end groove through the bottom surface of the support column 22. The design of the first concave platform 23 on the receiving block 2 ensures that it can accommodate the previous rear axle 5 and play a role in stable support, laying the foundation for receiving another rear axle 5.

[0059] The cavity further includes a second connecting plate groove 37 recessed inward from the top surface 3 of the main body and communicating with the rear axle body groove 33. The second connecting plate groove 37 is adapted to the suspension connecting plate 52 of the rear axle 5. The second concave platform 24 and the second connecting plate groove 37 support the end assembly of another rear axle 5, and the rear axle body groove 33 houses the rear axle body 51 of the another rear axle 5, thereby realizing the accommodation of the second rear axle 5 in the same cavity. In this embodiment, the second concave platform 24 supports the second connecting arm 54 of another rear axle 5, the second connecting plate groove 37 supports the suspension connecting plate 52 of this rear axle 5, and the first connecting arm 53 of this rear axle 5 hangs above the second connecting arm groove 36.

[0060] Due to the supporting and isolating effect of the receiving block 2, rigid contact between the upper and lower rear axles 5 is avoided, ensuring the reasonable utilization of the packaging space. It can be seen that the two rear axles 5 housed in the cavity are placed oppositely in the vertical direction, that is: the lower rear axle 5 is placed forward in the posture as Figure 9 shown, and the upper rear axle 5 is placed backward in the posture as Figure 10 shown. This accommodation method is not only beneficial to saving the longitudinal packaging space, but also beneficial to the center of gravity of the appliance main body 1 being centered, and it is not likely to tip over during storage and transportation.

[0061] The specific implementation manner of the present invention further provides a packaging method for a logistics appliance for a rear axle. This packaging method is implemented based on the aforementioned logistics appliance of the invention and includes the following steps:

[0062] Step 1: Place the rear axle 5 with its top surface facing upwards in the cavity of the appliance body 1. The rear axle body 51 of the rear axle 5 is received in the rear axle body groove 33 of the cavity, and the end components of the rear axle 5 are received in the end grooves of the cavity, that is: the suspension connecting plate 52 is received in the first connecting plate groove 34, the first connecting arm 53 is received in the first connecting arm groove 35, and the second connecting arm 54 is received in the second connecting arm groove 36. Specifically, as shown in Figure 11 and Figure 12 , they are respectively the top perspective view and the top view of the process of the appliance body receiving the automotive rear axle in process 1;

[0063] Step 2: The receiving block 2 is clamped in the card slot 32 of the appliance body 1 via the card block 21, and the first concave platform 23 of the receiving block 2 is pressed against the end component of the rear axle 5, that is, the suspension connecting plate 52. Specifically, as shown in 13 and Figure 14 , they are respectively the top perspective view and the top view of the process of the appliance body receiving the automotive rear axle in process 2.

[0064] Step 3: Place another rear axle 5 with its top surface facing downwards in the cavity of the appliance body 1. The rear axle body 51 of this rear axle 5 is received in the rear axle body groove 33 of the cavity, and the end components of this rear axle 5 are supported on the second connecting plate groove 37 and the second concave platform 24 of the receiving block 2. More specifically, the second concave platform 24 supports the second connecting arm 54 of this rear axle 5, the second connecting plate groove 37 supports the suspension connecting plate 52 of this rear axle 5, and the first connecting arm 53 of this rear axle 5 hangs above the second connecting arm groove 36. Specifically, as shown in Figure 15 and Figure 16 , they are respectively the top perspective view and the top view of the process of the appliance body receiving the automotive rear axle in process 3.

[0065] Step 4: Stack another appliance body 1 on the appliance body 1, and the limit post 31 of the lower appliance body 1 is inserted into the limit slot of the upper appliance body 1. Specifically, as shown in Figure 17 , it is the top perspective view of the process of the appliance body receiving the automotive rear axle in process 4.

[0066] The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
