[0035] The utility model will be explained in detail in combination with each embodiment shown in the drawing, but it should be explained that these embodiments are not the limitation of the utility model, and the equivalent transformation or replacement of function, method or structure made by the ordinary skill in the art according to these embodiments all belong to the protection scope of the utility model.

[0036] Refer to the drawing Figures 1-15As shown, the cargo carrying device in the embodiment includes a base body 2, a cover body 1 which is opened and can be closed to the base body 2 to form a carrying cavity, and an additional structure 3 attached to the base body 2 and / or the cover body 1, which extends to form a reinforcing structure 3-1 of one of the base body or the cover body, and is flush with the edge of the base body 2 or the cover body 1, overlaps the edge of the other, so that the overlapping part of the base body 2 and the cover body 1 forms a substantially flush overlapping. The base body and the cover body in the embodiment can be understood as a lower shell and an upper shell. In the prior art, the lower shell and the upper shell are directly butted and then buckled, but this way cannot well ensure that the lower shell and the upper shell are in complete and substantially flush overlapping. On the other hand, the carrying cavity is a single layer structure, which makes the strength of the entire cavity weak, and thus seriously affects the service life of the product and causes great safety problems when facing the head-on situation of wind and the like. The scheme in the embodiment can make the base body 2 or the cover body 1 form a local double-layer structure, and thus the strength is greatly increased. Especially, the base body 2 located below needs greater carrying capacity. This setting can increase the carrying capacity of the bottom, and thus facilitates support.

[0037] The substantially flush in the embodiment refers to that the connection part of the upper cover and the base body is flush at the contact part of the two surfaces, and there is no gap or excessive interference.

[0038] The additional structure 3 in the embodiment forms a double-layer structure and also serves the purpose of the overlapping edge. Especially, it is flush with one of the base body or the cover body at first, at this time the structure is a double-layer structure, and then is flush to form a double-layer overlapping, and at this time the other of the base body or the cover body is just in contact with the double-layer overlapping. Compared with the single overlapping and the double-layer overlapping, the contact structure is more, and once a small deviation occurs due to impact force and the like, better overlapping effect can be ensured.

[0039] In the embodiment, the additional structure is first increased, which is directly attached to the base body 2 or the cover body 1 to form a double-layer structure, and then the double-layer overlapping effect with the base body or the cover body is achieved, which is a hit many birds with one stone.

[0040] In order to ensure better strength, the reinforcing structure 3-1 in the embodiment forms a reinforcing area from the base body 1 to the cover body 2, and thus the reinforcing area to some extent forms a reinforcing direction from the base body to the cover body, instead of simply reinforcing one side, and the trajectory of the reinforcing area is arranged along the circumference of the cover body 2. At this time, the reinforcing area is a circle, instead of a part, and the double-layer of the entire carrying assembly is achieved. In the embodiment, the reinforcing structure 3-1 is a circle of structure arranged along the circumference of the cover body 2 or the base body 1, which can form a reinforcing ring, and the cover body 2 or the base body 1 is located in the reinforcing ring, which improves the strength of the edge and also forms protection.

[0041] In this embodiment, the reinforcing structure 3-1 is attached to the inner wall of the cover 1 or the inner wall of the base 2, so that a locally stacked double-layer stress area is formed. The local attachment and stacking here further have no gap between them, forming a better seal and good waterproof performance, especially at the diagonal, the bending or edge changing of the base 2 or the cover 1. This arrangement improves the waterproof effect.

[0042] In this embodiment, the base 2 forms a groove-shaped structure, and the additional structure 3 is attached to the side wall of the groove-shaped structure. In this embodiment, the additional structure 3 not only has a reinforcing structure, but also has a groove-shaped body at the bottom of the body, which is attached to the groove-shaped structure, and then located in the groove-shaped structure of the base 2. Then the entire groove-shaped structure forms a double-layer structure, and the outer side of the groove-shaped structure is attached to the side wall of the groove-shaped structure, so that the double-layer structure of the base 2 increases in strength. At this time, the contact surface is larger, and the strength is much greater than the strength provided by the reinforcing structure 3-1. At this time, for the base 2, the top and the cover 1 have a certain double-layer structure, and the inner wall is a double-layer structure formed by the entire additional structure 3, which ensures the strength of the connection between the base 2 and the cover 1.

[0043] In this embodiment, the groove-shaped structure is locally formed with a protrusion to increase its strength, such as a partial protrusion at the bottom to form a protruding strip. At this time, the corresponding position of the additional structure 3 will also be protruding to form a protruding strip. For reference, see Figure 2. Figure 15 In order to increase the strength here, the two protruding strips will be glued between them to ensure the connection strength, as shown by the glue layer 5 in the figure.

[0044] In this embodiment, the reinforcing structure 3-1 is introduced, which is at least bent once after the extension of the additional structure 3 and forms a U-shaped reinforcing cavity with the additional structure 3. At this time, the outer side of the U-shaped reinforcing cavity is attached to the edge of the base 2 or the cover 1. In this embodiment, the body of the additional structure 3 forms a groove-shaped body attached to the base 2, and then the U-shaped reinforcing cavity is formed. The outer side of the base 2 forms the attachment of the cover 1, so that the sealing performance of the attachment is enhanced.

[0045] Specifically, the additional structure 3 is a ring-shaped structure, and the U-shaped reinforcing cavity is located in the upper part of the additional structure 1 along the height direction. That is, in this embodiment, the reinforcing structure 3-1 is arranged at the top, which is close to the cover 1, providing a basis for subsequent assembly and locking.

[0046] In this embodiment, the additional structure 3 forms an extension inwardly to form a bearing surface 3-2, and a plurality of reinforcing ribs 3-3 are arranged on the bearing surface 3-2. In this embodiment, the additional structure 3 forms a reinforcing structure on the outer side and also forms a bearing surface 3-2 on the inner side. The bearing surface 3-2 is formed along the inner wall of the additional structure 3 to form a ring. The additional structure 3 forms a vertical reinforcement, and the bearing surface 3-2 forms a horizontal reinforcement, thereby increasing the overall strength. The reinforcing ribs 3-3 further form a reinforcement, which can be horizontal or vertical.

[0047] In the bearing cavity, the end portion has a short fitting distance, but the bearing force does not decrease. In order to enhance the strength at this position, the density of the reinforcing ribs 3-3 at the two ends of the bearing cavity is large, and the density of the reinforcing ribs 3-3 at the side portion is small. That is, the density of the reinforcing ribs 3-3 is small in the length direction of the bearing cavity, and the density of the reinforcing ribs 3-3 is large in the width direction of the bearing cavity. The spacing between adjacent reinforcing ribs 3-3 at the two ends of the bearing cavity is smaller than the spacing between adjacent reinforcing ribs 3-3 at the two sides of the bearing cavity.

[0048] In order to increase the sealing performance, a sealing member 4 is further arranged to isolate the overlapping portion of the base body 2 and the cover body 1 from the bearing cavity. The sealing member 4 isolates the overlapping portion of the base body 2 and the cover body 1 from the outside, thereby preventing water and other substances from entering. Further, in this embodiment, the sealing member 4 forms a sealing ring, which is arranged on the upper side of the U-shaped reinforcing cavity. The side portion of the sealing ring extends to cover the upper portion of the U-shaped reinforcing cavity and abuts against the inner wall of the cover body 1. The sealing ring forms a sealing isolation between the upper portion and the cover body 1. Then, a layer of isolation is further formed at the overlapping portion of the cover body 1 and the base body 2. The entire ring-shaped structure forms a double-layer isolation, thereby achieving a good isolation and waterproof effect.

[0049] In order to achieve perfect assembly and avoid excessive structure exposure, a locking groove 3-4 is further arranged on the additional structure 3 in this embodiment. During locking of the cover body 1 and the base body 2, the locking mechanism can be arranged in the locking groove 3-4, thereby avoiding exposure.

[0050] In order to further ensure the sealing performance, in this embodiment, the U-shaped reinforcing cavity is glued at the position where the U-shaped reinforcing cavity contacts the base body 2 to form the overlapping portion of the cover body 1. The U-shaped reinforcing cavity and the base body 2 are firmly connected, and even if subjected to external force, they are not easily separated. Figures 14-15 The glue layer 5 formed in the edge protrusion and other positions can obviously increase the glue layer and improve the safety.
