[0030] In this embodiment, the central frame assembly 1 is independently formed and can be assembled with other components required by the automatic guided transport vehicle. Other components can be replaced at any time according to the actual application scenario, and the versatility and flexibility are higher. The central frame assembly 1 includes a top 11 and a bottom 12 that are parallel to each other and spaced apart, and both are H-shaped, so that the top 11 and the bottom 12 can be designed as different internal structures, such as the top 11 is specially designed to include a first bearing portion 111, a second bearing portion 112 that is parallel to the first bearing portion 111 and spaced apart, and a third bearing portion 113, and the third bearing portion 113 is arranged between the first bearing portion 111 and the second bearing portion 112 and is connected to the first bearing portion 111 and the second bearing portion 112, respectively, so as to improve the bearing capacity of the top 11 with a bearing surface, thereby improving the bearing capacity of the automatic guided transport vehicle. In addition, the top 11 and the bottom 12 are connected by a plurality of brackets 13 to form a receiving space 10, so that other components of the automatic guided transport vehicle can be assembled in this receiving space, while improving the bearing capacity and reducing the space volume occupied by the automatic guided transport vehicle.

[0031] Please continue reading Figure 1 and Figure 2 The first bearing portion 111 of the top 11 includes two first long sides A1 arranged in parallel and spaced apart, and two first short sides B1 arranged in parallel and spaced apart, and the two first short sides B1 connect the two first long sides A1; the first bearing portion 111 may also include two third short sides B3, which are respectively arranged outside the two first short sides B1 and also connect the two first long sides A1. The two third short sides B3 may be arranged as follows: Figure 2 The bent shape shown in the figure increases the bearing area of ​​the top 11 on the one hand, and converts the sharp right angle formed when the first long side A1 away from the second bearing portion 112 is connected to the first short side B1 into a bevel formed when the first long side A1 is connected to the bent third short side B3 on the other hand, thereby reducing the probability of damage to the automatic guided transport vehicle due to collision during operation.

[0032] The second bearing portion 112 includes two second long sides A2 arranged in parallel and at intervals, and two second short sides B2 arranged in parallel and at intervals, and the two second short sides B2 connect the two second long sides A2; the second bearing portion 112 may also include two fourth short sides B4, which are respectively arranged outside the two second short sides B2 and also connect the two second long sides A2. The two fourth short sides B4 may be arranged as follows: Figure 2 The bent shape shown in the figure increases the bearing area of ​​the top 11 on the one hand, and converts the sharp right angle formed when the second long side A2 away from the first bearing portion 111 is connected with the second short side B2 into a bevel formed when the second long side A2 is connected with the bent fourth short side B4 on the other hand, thereby reducing the probability of damage to the automatic guided transport vehicle due to collision during operation.

[0033] The third bearing part 113 includes two parallel and spaced-apart beams C1, and the two beams C1 connect the first bearing part 111 and the second bearing part 112, so that the top 11 formed by the first bearing part 111, the second bearing part 112 and the third bearing part 113 becomes a whole and has a larger bearing area, which can improve the bearing strength of the top 11.

[0034] For further information, please refer to Figure 2 , one end of each of the two cross beams C1 extends between the two first long sides A1 and is connected to the two first long sides A1 respectively, and the other end of each of the two cross beams C1 extends between the two second long sides A2 and is connected to the two second long sides A2 respectively. Among them, the portion of one of the two first long sides A1 close to the second bearing portion 112 located between the two cross beams C1 is removed, and the portion of one of the two second long sides A2 close to the first bearing portion 111 located between the two cross beams C1 is removed. Such an arrangement can prevent the two cross beams C1 from being cut off, so that the two cross beams C1 are connected to the first bearing portion 111 and the second bearing portion 112 as a whole, and the whole cross beam C1 has higher bending resistance, thereby further improving the bearing strength of the top 11.

[0035] For further information, please refer to Figure 2 The top 11 further includes a first reinforcing beam D1 and a second reinforcing beam D2 disposed between the two cross beams C1. One end of each of the first reinforcing beam D1 and the second reinforcing beam D2 is connected to one of the two cross beams C1, and the other end is connected to the other of the two cross beams C1. One of the two cross beams C1 and the first reinforcing beam D1 and the second reinforcing beam D2 form a triangle. Specifically, one end of each of the first reinforcing beam D1 and the second reinforcing beam D2 is connected to a portion of one of the two cross beams C1 located between the first bearing portion 111 and the second bearing portion 112, that is, Figure 2 The left side of the cross beam C1 is connected to one end of the first reinforcement beam D1 and the second reinforcement beam D2 at a portion between the first bearing portion 111 and the second bearing portion 112. The other end of each of the first reinforcement beam D1 and the second reinforcement beam D2 is connected to the other end of the two cross beams C1 located between the two first long sides A1 and the two second long sides A2, that is, Figure 2 The portion of a cross beam C1 on the right side of the middle part located between the two first long sides A1 is connected to the other end of the first reinforcement beam D1. Figure 2 The portion of the cross beam C1 on the right side between the two second long sides A2 is connected to the other end of the second reinforcement beam D2. Figure 2The cross beam C1 on the right side of the middle part forms a triangular structure with the first reinforcing beam D1 and the second reinforcing beam D2, which can enhance the bending resistance of the three sides of the triangle and make the structure of the third bearing part 113 more stable and pressure-resistant. When the top 11 carries goods, the triangular structure helps to reasonably and evenly distribute the weight of the goods, thereby further improving the bearing capacity of the top 11.

[0036] For further information, please refer to Figure 2 The top 11 further includes a third reinforcing beam D3 and a fourth reinforcing beam D4 disposed between the two cross beams C1. The third reinforcing beam D3 and the fourth reinforcing beam D4 are disposed on both sides of the triangle. One end of each of the third reinforcing beam D3 and the fourth reinforcing beam D4 is connected to one of the two cross beams C1, and the other end is connected to the other of the two cross beams C1. Preferably, the other end of the third reinforcing beam D3 is connected to Figure 2 The cross beam C1 on the right side of the middle part is connected to the connection point of the first long side A1 away from the second bearing portion 112, and the other end of the fourth reinforcement beam D4 is connected to the Figure 2 The cross beam C1 on the right side of the middle is connected to the connection point of the second long side A2 away from the first bearing part 111. Preferably, the third reinforcement beam D3 is arranged in parallel with the first reinforcement beam D1 and is connected through a plurality of first connecting strips E1, and the fourth reinforcement beam D4 is arranged in parallel with the second reinforcement beam D2 and is connected through a plurality of second connecting strips E2; a plurality of first connecting strips E1 are arranged in parallel and are connected through a plurality of second connecting strips E2. Such an arrangement can divide the bearing surface of the third bearing part 113 into a plurality of triangles, and the plurality of triangles are connected by a plurality of connecting strips, so that the structure of the third bearing part 113 is more stable and pressure-resistant. When the top 11 carries goods, the plurality of triangular structures help to further disperse the weight of the goods reasonably and evenly, thereby further improving the bearing strength of the top 11.

[0037] In addition, the top 11 may also include a fifth reinforcement beam D5 and a sixth reinforcement beam D6 which are parallel to each other and are arranged at Figure 2 The inner side of the triangle formed by a cross beam C1 on the right side of the middle part and the first reinforcement beam D1 and the second reinforcement beam D2, wherein each of the fifth reinforcement beam D5 and the sixth reinforcement beam D6 has one end connected to the first reinforcement beam D1, and the other end connected to the second reinforcement beam D2. Preferably, the fifth reinforcement beam D5 and the sixth reinforcement beam D6 are connected by at least one third connecting strip E3. Other connecting strips may be added between the reinforcement beams within the two cross beams C1, which is not limited in the present application. In this embodiment, as many reinforcement beams, connecting strips, etc. as reasonably possible are added within the existing bearing surface of the top 11, so that the structure of the third bearing portion 113 is more stable and pressure-resistant, and the bearing strength of the top 11 is further improved.

[0038] Please combine Figure 1 and Figure 2 See also Figure 3 , Figure 3 The schematic diagram of the structure of the bottom of a central frame assembly is a schematic diagram of an embodiment of the bottom, wherein the bottom 12 includes: a first support portion 121; a second support portion 122, which is parallel to and spaced apart from the first support portion 121; and a third support portion 123, which is disposed between the first support portion 121 and the second support portion 122 and is connected to the first support portion 121 and the second support portion 122, respectively, to improve the bearing capacity of the bottom 12, thereby improving the bearing capacity of the automatic guided transport vehicle. Specifically, the frame structure of the bottom 12 is similar to that of the top 11, wherein the first support portion 121 includes two first long sides F1 that are parallel and spaced apart, and two first short sides G1 that are parallel and spaced apart, and the two first short sides G1 connect the two first long sides F1; the first support portion 121 may also include two third short sides G3, which are respectively disposed on the outside of the two first short sides G1, and also connect the two first long sides F1, wherein the two third short sides G3 may be arranged as Figure 3 The bent shape shown, on the one hand, increases the bearing area of ​​the bottom 12, and on the other hand, converts the sharp right angle formed when the first long side F1 away from the second support portion 122 is connected to the first short side G1 into a bevel formed when the first long side F1 is connected to the bent third short side G3, thereby reducing the probability of damage to the automatic guided transport vehicle due to collision during operation.

[0039] The second support portion 122 of the bottom 12 includes two second long sides F2 that are parallel and spaced apart, and two second short sides G2 that are parallel and spaced apart, and the two second short sides G2 connect the two second long sides F2; ​​the second support portion 122 may also include two fourth short sides G4 that are respectively disposed outside the two second short sides G2 and also connect the two second long sides F2, wherein the two fourth short sides G4 may be arranged as Figure 3 The bent shape shown, on the one hand, increases the bearing area of ​​the bottom 12, and on the other hand, converts the sharp right angle formed when the second long side F2 away from the first support portion 121 is connected to the second short side G2 into a bevel formed when the second long side F2 is connected to the bent fourth short side G4, thereby reducing the probability of damage to the automatic guided transport vehicle due to collision during operation.

[0040] The third support portion 123 includes two parallel and spaced beams K1, and the two beams K1 connect the first support portion 121 and the second support portion 122, so that the bottom 12 formed by the first support portion 121, the second support portion 122 and the third support portion 123 becomes a whole, and has a large bearing area, which can improve the supporting strength of the bottom 12. A plurality of connecting members (not shown) parallel to the first long side F1 and a plurality of connecting members (not shown) parallel to the beams K1 can be further arranged between the two beams K1, forming a tic-tac-toe structure in the third support portion 123, which can improve the bearing strength of the bottom 12 on the one hand, and divide the accommodating space 10 into a plurality of accommodating spaces on the other hand, which is convenient for arranging other components.

[0041] For further information, please refer to Figure 3 , one end of each of the two cross beams K1 extends between the two first long sides F1 and is respectively connected to the two first long sides F1, and the other end of each of the two cross beams K1 extends between the two second long sides F2 and is respectively connected to the two second long sides F2. Among them, the portion of one of the two first long sides F1 close to the second support portion 122 located between the two cross beams K1 is removed, and the portion of one of the two second long sides F2 close to the first support portion 121 located between the two cross beams K1 is removed. Such an arrangement can prevent the two cross beams K1 from being cut off, so that the two cross beams K1 are connected to the first support portion 121 and the second support portion 122 as a whole, and the whole cross beam K1 has higher anti-bending performance, thereby further improving the supporting strength of the bottom 12.

[0042] In summary, the bottom 12 is H-shaped, and the top 11 is also H-shaped, so that the center frame assembly 1 is H-shaped with thickness as a whole, and its force-bearing principle is similar to that of an I-beam in a steel structure. The first load-bearing portion 111 connects the first support portion 121, and the second load-bearing portion 112 connects the second support portion 122, which is equivalent to two parallel brackets of the I-beam, and the third load-bearing portion 113 connects the third support portion 123, which is equivalent to the connecting crossbeam of the I-beam. The automatic guided transport vehicle is placed on a horizontal ground. When it is subjected to vertical downward pressure due to carrying goods, the center frame assembly 1 bends, and the top 11 undergoes compression deformation, that is, compressive stress occurs. The closer to the upper surface, the more severe the compression; the bottom 12 undergoes tensile deformation, that is, tensile stress occurs. The closer to the lower surface, the more severe the tensile stress. The present application uses a plurality of brackets 13 to connect the top 11 and the bottom 12, respectively, and designs the top 11 and the bottom 12 as different internal structures to improve their anti-bending and anti-compression properties, thereby improving the load-bearing capacity of the automatic guided transport vehicle. The middle layer of the I-beam is neither stretched nor compressed, so it is stress-free. The present application sets the middle as an accommodating space, reasonably arranges the arrangement of its various components without affecting the carrying capacity of the automated guided transport vehicle, and can reduce the space volume occupied by the automated guided transport vehicle.

[0043] Furthermore, the accommodation space 10 formed between the top 11 and the bottom 12 includes: a first accommodation space 101 located between the first support portion 121 and the first bearing portion 111, a second accommodation space 102 located between the second support portion 122 and the second bearing portion 112, and a third accommodation space 103 located between the third support portion 123 and the third bearing portion 113. For the sake of clarity, each accommodation space is represented by its projection on the bottom 12. For details, please refer to Figure 4 , Figure 4 This is a structural diagram of another embodiment of the bottom of the central frame assembly, in which only the main frame of the bottom 12 is schematically drawn. Specifically, in a direction perpendicular to the first support portion 121, the first accommodation space 101 and the second accommodation space 102 are located on both sides of the third accommodation space 103. Other components of the automatic guided transport vehicle of the present application can be assembled in each accommodation space, and other components can also be replaced at any time according to actual needs in different application scenarios, thereby improving the flexibility of the use of the automatic guided transport vehicle and reducing the space volume occupied by the automatic guided transport vehicle without affecting the load-bearing capacity.

A handle 46 can also be provided on the side surface of the upper mounting plate 42 away from the lower mounting plate 43 to facilitate the adjustment of the height of the driven wheel 41. On the one hand, the present embodiment enables the driven wheel assembly 4 to be detachably connected to the center frame assembly 1. On the other hand, the structure of the driven wheel assembly 4 except for the connecting piece 45 can be moved up and down as a whole along the axial direction of the connecting column 44, thereby adjusting the range of the driven wheel 41 leaking out from the bottom 12 of the center frame assembly 1, thereby improving the flexibility of use of the automatic guided transport vehicle of the present application.
