[0037] Existing logistics trolleys are made of metal materials such as stainless steel. Although metal materials have good structural strength and stability, they are not only too heavy and have high production costs, but even if a walking component is provided at the bottom of the logistics trolley, the operator still needs to exert a lot of force to push it, and a certain amount of noise is generated during the pushing process.

[0038] In view of this, an embodiment of the present application provides a logistics trolley, which aims to reduce the weight of the logistics trolley by designing the logistics trolley with metal materials as the supporting frame and other rigid materials with a density lower than that of metal as the main part of the logistics trolley, thereby solving the above-mentioned problems caused by the excessive weight of the logistics trolley.

[0039] The following is combined with Figure 1-8 The logistics trolley provided in the embodiment of the present application is introduced.

[0040] Combined with Figure 1 As shown, an embodiment of the present application provides a logistics trolley 100, including a box body 10 and a walking component 20 connected to the bottom of the box body 10. The walking component 20 can be a structure such as a walking wheel that can enable the logistics trolley 100 to move on the ground. This embodiment does not make too many restrictions on this.

[0041] The box body 10 of this embodiment includes a bottom wall 11, multiple side walls and multiple reinforcement components. The bottom wall 11 as a whole can be rectangular or approximately rectangular. Of course, it can also be a polygon such as a hexagon. This embodiment is introduced by taking the bottom wall 11 as a rectangle as an example to facilitate technical personnel in this field to better understand it by referring to the drawings.

[0042] A plurality of side walls are arranged around the bottom wall 11, and a gap is provided between two adjacent side walls. When the side wall of the present embodiment is rectangular, the number of the side walls is four, and the four side walls are a first side wall 12, two second side walls 13 located on both sides of the first side wall 12 in the first direction X, and a third side wall 14 used as a door. The first direction X is a direction parallel to the inner wall surface of the bottom wall 11. When the logistics trolley 100 is actually used, the first direction X can be a horizontal direction.

[0043] A plurality of reinforcing components are installed on the bottom wall 11, each reinforcing component is located between two adjacent side walls and is used to connect the two adjacent side walls. The number of reinforcing components matches the number of side walls to connect and fix the two adjacent side walls. When the side walls include the first side wall 12, the second side wall 13 and the third side wall 14, the reinforcing components include two first reinforcing components 15 and two second reinforcing components 16, wherein one first reinforcing component 15 is connected between one side of the first side wall 12 and one of the second side walls 13, and another first reinforcing component 15 is connected between the other side of the first side wall 12 and another second side wall 13. One of the second reinforcing components 16 is connected between one side of the third side wall 14 and one of the second side walls 13, and another second reinforcing component is gradually connected between the other side of the third side wall 14 and another second side wall 13.

[0044] The side wall may be connected to the bottom wall 11 , or the side wall and the bottom wall 11 may be connected only through the above-mentioned reinforcement assembly, so that the side wall and the bottom wall 11 may move relative to each other to fold the box body 10 .

[0045] Different from the side wall of the box 10 in the related art, which is made entirely of metal material, the side wall of this embodiment is at least partially made of a non-metal first material part, and then reinforced by a reinforcement component. "At least partially" can be understood as a part or all of the side wall, and the reinforcement component is at least partially a metal part. The density of the first material part is less than the density of the metal part, so that under the box 10 of the same volume and storage space, the weight of the logistics trolley 100 using this embodiment will be less than the weight of the logistics trolley 100 in the related art, which facilitates the movement of the logistics trolley 100 and reduces the noise during the movement.

[0046] In some examples, optionally, the first material portion is a rigid polymer material portion, and the rigid polymer material refers to a polymer material with certain strength and rigidity, including polypropylene (PP), polycarbonate (PC), polystyrene (PS), polyphenylene ether (PPO), polyetheretherketone (PEEK), polyphenylene sulfide (PPS), etc.

[0047] The above-mentioned rigid polymer material has the characteristics of light weight and high structural strength, and can ensure the structural stability of the side wall while reducing weight.

[0048] In some examples, optionally, the first material part is a plastic part, that is, the material of the side wall of the embodiment of the present application may include plastic, or the side wall may be completely made of plastic. The plastic may be common polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc., which not only has the characteristics of light weight and high structural strength, but also is cheaper than metal, which can reduce the production cost of the logistics trolley 100.

[0049] Combined with Figure 2 As shown, in some examples, optionally, each reinforcement component of the present embodiment is provided with two connecting grooves 17, and the two connecting grooves 17 are opened one by one on both sides of the reinforcement component, and the side edges of two adjacent side walls are accommodated one by one in the two connecting grooves 17 of a reinforcement component, and then the side edges of the two side walls are fixed by a first fastener 18 inserted in the connecting groove 17.

[0050] The length direction of the connecting groove 17 is set along the second direction Y in the figure. The connecting groove 17 is an open groove at both ends along the second direction Y, so as to facilitate the insertion of the side edge of the side wall. The second direction Y is a direction perpendicular to the inner wall surface of the bottom wall 11. When the logistics trolley 100 is actually used, the second direction Y can be a vertical direction.

[0051] The number of the first fasteners 18 can be one or more. When the number of the first fasteners 18 is more than one, the first fasteners 18 are arranged at intervals along the second direction Y and installed on the side wall of the connecting groove 17 .

[0052] In some examples, optionally, the first fastener 18 of the present embodiment includes a bolt or a rivet. When the first fastener 18 includes a bolt, the bolt can be passed through at least one side or bottom edge of the connecting groove 17 and threadedly connected to the side edge of the side wall. A locking nut threadedly connected to the bolt can also be arranged on the outer wall surface of the side wall of the connecting groove 17 to improve the stability of the bolt after installation.

[0053] Combined with Figure 1 and attached Figure 2 As shown, when the multiple side walls of this embodiment include the aforementioned first side wall 12 and two second side walls 13 located on both sides of the first side wall 12 in the first direction X, the multiple reinforcement components include a first reinforcement component 15 connected between the first side wall 12 and the second side wall 13, the number of the first reinforcement components 15 is two, and each first reinforcement component 15 forms a group with one of the side walls and is located on the same side of the bottom wall 11.

[0054] In some examples, optionally, the first reinforcement component 15 includes a first connecting member 151, a second connecting member 152, and a plurality of supporting members 153 connected between the first connecting member 151 and the second connecting member 152, the plurality of supporting members 153 are arranged at intervals along the second direction Y, the length direction of the supporting members 153 can be set along the first direction X, the first connecting member 151 is connected to the first side wall 12, and the second connecting member 152 is connected to the second side wall 13.

[0055] In some embodiments, the first connecting member 151 of this embodiment is a C-shaped steel, which forms the above-mentioned connecting groove 17, and the two side edges of the first side wall 12 are accommodated in the two accommodating grooves of the C-shaped steel in a one-to-one correspondence.

[0056] The second connecting member 152 of this embodiment may be directly connected to the second side wall 13 , in which case the second connecting member 152 may be provided with a connecting groove 17 (this embodiment is not shown in the figure), or the second connecting member 152 may be indirectly connected to the second side wall 13 .

[0057] like Figure 1 As shown in the figure, the second connecting member 152 of this embodiment is connected to the second side wall 13 through the third connecting member 154, and the third connecting member 154 is located between the second connecting member 152 and the second side wall 13. The third connecting member 154 can be a C-shaped steel, so that one side of the third connecting member 154 forms a receiving groove connected to the second side wall 13, and the other side of the third connecting member 154 is hinged to the second connecting member 152 through the first hinge 155, so that the two second side walls 13 can rotate relative to the first reinforcement component 15, thereby facilitating the folding of the box body 10.

[0058] Combined with Figure 1 , Attachment Figure 3 and attached Figure 4 As shown, in some examples, optionally, the multiple side walls also include a third side wall 14 located between the two second side walls 13 and opposite to the first side wall 12 in a third direction Z, and the third direction Z is perpendicular to the first direction X and parallel to the inner wall surface of the bottom wall 11. When the logistics trolley 100 is actually used, the third direction Z is a horizontal direction.

[0059] The third side wall 14 of this embodiment can serve as the door of the logistics trolley 100 . Therefore, the third side wall 14 is designed to include two sub-walls 141 arranged side by side along the first direction X. The opening and closing of the two sub-walls 141 realizes the opening and closing of the door of the box body 10 .

[0060] Correspondingly, the multiple reinforcement components of this embodiment include a second reinforcement component 16 located between the second side wall 13 and the sub-wall body 141. The second reinforcement component 16 has a different structure from the first reinforcement component 15. The second reinforcement component 16 includes a fourth connecting member 161 and a fifth connecting member 162. The fourth connecting member 161 is installed on the bottom wall 11 and connected to the second side wall 13. The fifth connecting member 162 is hinged to the fourth connecting member 161 through a second hinge 163 and connected to the sub-wall body 141.

[0061] The fourth connecting member 161 and the fifth connecting member 162 of this embodiment are both provided with the above-mentioned connecting groove 17. In some embodiments, the fourth connecting member 161 and the fifth connecting member 162 may also be C-shaped steel, and the two side edges of the two second side walls 13 are accommodated in the connecting grooves 17 of the two fourth connecting members 161 in a one-to-one manner, and the two side edges of the two sub-wall bodies 141 are accommodated in the connecting grooves 17 of the two fifth connecting members 162 in a one-to-one manner, and the side edges located in the connecting grooves 17 of the fourth connecting member 161 and the fifth connecting member 162 can be locked by a second fastener (not shown in the figure).

[0062] This structure allows the two sub-walls 141 to rotate relative to the two second side walls 13, thereby realizing the opening and closing of the box body 10.

[0063] In some examples, optionally, the side of each sub-wall body 141 facing another sub-wall body 141 is coated with a metal reinforcement 142, which may also be a C-shaped steel structure. The metal reinforcement 142 is used to improve the structural stability of the side of the sub-wall body 141 away from the fifth connecting member 162.

[0064] Combined with Figure 7 and attached Figure 8 As shown, in some examples, optionally, the bottom wall 11 of the present embodiment is at least partially a second material portion, for example, the first portion of the bottom wall 11 is the second material portion, the second material portion is made of the same material as the aforementioned first material portion, for example, both may be plastic, the second portion is a metal material, the first portion is connected to the second portion, and the connection method may be that the second portion is arranged outside the first portion, or the first portion and the second portion are two hinged plate structures to facilitate the folding of the bottom wall 11.

[0065] Combined with Figure 4-6 As shown, in some examples, optionally, the side wall of the present embodiment is provided with a hollow structure. For example, the side wall may be designed to include a frame and a plurality of diagonal braces connected to the frame, and the two side edges of the frame are connected one by one to two adjacent reinforcement components, forming a hollow structure between two adjacent diagonal braces.

[0066] As 1 and Figure 5As shown in the figure, the first side wall 12 of this embodiment includes a first diagonal brace 121 and a second diagonal brace 122 intersecting in the length direction. The number of the first diagonal brace 121 and the second diagonal brace 122 are both multiple to form a grid-like hollow.

[0067] like Figure 1 and Figure 6 As shown in , the second side wall 13 of this embodiment includes a plurality of third diagonal braces 131 , the plurality of third diagonal braces 131 are parallel to each other and arranged at intervals, and the length direction of the third diagonal braces 131 forms an angle with the third direction Z.

[0068] like Figure 1 and Figure 2 As shown in the figure, different from the diagonal brace structure of the aforementioned first side wall 12 and the second side wall 13, each sub-wall body 141 of the third side wall 14 of this embodiment includes three diagonal brace areas from top to bottom, and each diagonal brace area includes multiple fourth diagonal braces 1411. The inclination direction of the fourth diagonal brace 1411 located in the middle area intersects with the length direction of the fourth diagonal brace 1411 in the upper and lower areas. The "intersection" described in this embodiment includes vertical and acute angles.

[0069] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
