[0002] With the increasing degree of automation in the manufacturing industry, transport vehicles can perform operations such as transferring, conveying, loading, and receiving materials and semi-finished products in a variety of scenarios. That is, transport vehicles have different usage functions in different scenarios. Existing transport vehicles mostly use AGV automatic transportation to achieve the effect of smooth transportation, but in actual application, AGV-driven vehicles need to occupy a larger movement space. At the same time, the size of the AGV-driven vehicle itself also requires the transport vehicle to make corresponding structural avoidances, not to mention that the purchase cost of the AGV-driven vehicle is also relatively high. In some small-scale or external temporary scenarios, the use of AGV vehicles has limitations.

[0003] In particular, in the installation scenario of photovoltaic modules, since photovoltaic modules are assembled in batches, the temporary assembly stations and transportation stations on site mostly rely on manual operations. For example, users control existing equipment such as trailers and forklifts to transport photovoltaic modules. In outdoor scenarios, the flatness of the ground cannot be guaranteed, and there are vibrations and other impacts on the photovoltaic modules during transportation, which limits the transportation rate to a lower range, affecting the installation efficiency of photovoltaic modules and slowing down the automated installation process of photovoltaic modules.

[0074] See also Figures 1 to 5 The present embodiment provides a chain-driven shock-absorbing transport vehicle, including a lower frame assembly 1, an upper frame assembly 2 and a shock-absorbing assembly 3. The lower frame assembly 1 includes a first base 11, a first moving wheel group 12, a first chain group 13 and a first driving unit 14. The first driving unit 14 is connected to the first moving wheel group 12 through the first chain group 13. The first moving wheel group 12 is arranged below the first base 11; the upper frame assembly 2 includes a first connecting plate 21, a second connecting plate 22 and a first crossbeam 23. The first connecting plate 21 and the second connecting plate 22 are arranged opposite to each other. The first crossbeam 23 is arranged on the first connecting plate 21. The shock absorbing assembly 3 is arranged between the first beam 23 and the first base 11, and the shock absorbing assembly 3 includes an adjusting member 31, at least one supporting rod 32 and at least one elastic member 33. The supporting rod 32 is arranged on the first beam 23, and the elastic member 33 is sleeved under the supporting rod 32. One end of the elastic member 33 abuts against the first beam 23, and the other end of the elastic member 33 abuts against the first base 11. The upper part of the supporting rod 32 protrudes out of the first beam 23, and the upper part of the supporting rod 32 is sleeved with an adjusting member 31, and the adjusting member 31 is used to adjust the length of the supporting rod 32 extending downward.

[0075] In this embodiment, the first base 11 serves as a supporting body, a first moving wheel set 12 is provided below the first base 11, a first driving unit 14 is provided on the first base 11, and a first chain set 13 is provided between the output end of the first driving unit 14 and the first moving wheel set 12, for realizing a transmission connection between the first driving unit 14 and the first moving wheel set 12. Optionally, the first driving unit 14 may be a servo motor, and the reciprocating movement function of the current transport vehicle may be realized through the first driving unit 14, the first chain set 13 and the first moving wheel set 12.

[0076] For details, please refer to Figure 2 and Figure 3 In some embodiments, the first driving unit 14 is arranged on the first connecting plate 21 or the second connecting plate 22, the first moving wheel group 12 includes a first connecting shaft 121 and two first moving wheels 122, and the two first moving wheels 122 are respectively sleeved on both ends of the first connecting shaft 121; the first chain group 13 includes a first chain, a first driving wheel and a first driven wheel, the first driving wheel is sleeved on the first driving unit 14, the first driven wheel is connected to the first connecting shaft 121, and the first chain is respectively sleeved on the first driven wheel and the first driving wheel.

[0077] That is, the first driving unit 14 is arranged on the upper frame assembly 2. The first moving wheel set 12 includes two relatively arranged first moving wheels 122 and a first connecting shaft 121 arranged between the two first moving wheels 122. The first connecting shaft 121 can be movably connected to the first base 11 through a bearing. A first driven wheel is sleeved on the first connecting shaft 121. The first driving wheel is connected to the output end of the first driving unit 14. Both the first driving wheel and the first driven wheel are sprocket structures for cooperating with the first chain, and both the first driving wheel and the first driven wheel are arranged inside the first chain. During use, the first driving wheel rotates driven by the first driving unit 14, driving the first chain to rotate, thereby driving the first driven wheel to rotate, and further causing the first connecting shaft 121 to rotate, ultimately realizing the rotation operation of the two first moving wheels 122 and achieving the movement of the entire first base 11.

[0078] It can be understood that the diameter of the first moving wheel 122 can be set according to actual needs. For example, when there are only two first moving wheels 122 under the first base 11, first moving wheels 122 with a larger diameter can be selected to facilitate the support of the first base 11; when the number of the first moving wheel sets 12 is multiple, first moving wheels 122 with a smaller diameter can be selected. This embodiment does not limit this.

[0079] Further, please refer to Figure 3 , in some embodiments, the lower frame assembly 1 further includes a second moving wheel set 15 and a second chain set 16. The second moving wheel set 15 is arranged opposite to the first moving wheel set 12; the second moving wheel set 15 includes a second connecting shaft 151 and two second moving wheels 152, and the two second moving wheels 152 are respectively sleeved at both ends of the second connecting shaft 151; the second chain set 16 includes a second chain, a second driving wheel and a second driven wheel. The second driving wheel is sleeved on the first connecting shaft 121, the second driven wheel is connected to the second connecting shaft 151, and the second chain is respectively sleeved on the second driven wheel and the second driving wheel.

[0080] In this embodiment, the second moving wheel set 15 and the first moving wheel set 12 are arranged opposite to each other in the front - rear direction of the transport vehicle. For example, when the first moving wheel set 12 is at the position of the front wheels, the second moving wheel set 15 is at the position of the rear wheels; another example is that when the first moving wheel set 12 is at the position of the rear wheels, the first moving wheel set 12 is at the position of the front wheels.

[0081] In this embodiment, the second moving wheel set 15 and the first moving wheel set 12 are drivingly connected through the second chain set 16. Specifically, the second moving wheel set 15 includes a second connecting shaft 151 and two relatively arranged second moving wheels 152. A second driven wheel is provided on the second connecting shaft 151, and a second driving wheel is sleeved on the first connecting shaft 121 synchronously. The first connecting shaft 121 and the second connecting shaft 151 are drivingly connected through the second chain. In this embodiment, the second moving wheels 152 and the first moving wheels 122 can have the same structure or can adopt rollers with different diameters. This embodiment does not limit this.

[0082] Through the settings of the first moving wheel set 12, the second moving wheel set 15, the first driving unit 14, the first chain set 13, and the second chain set 16, the moving unit of the entire transport vehicle is formed, which can drive other devices and components on the transport vehicle to move back and forth.

[0083] Furthermore, in this embodiment, an upper frame assembly 2 is further included. The upper frame assembly 2 includes a first connecting plate 21, a second connecting plate 22, and a first cross beam 23. Among them, the first connecting plate 21 and the second connecting plate 22 are relatively arranged and parallel to each other. Specifically, the first base 11 extends in the horizontal direction, and the first connecting plate 21 extends in the vertical direction. That is, the first connecting plate 21 is perpendicular to the first base 11, and then the second connecting plate 22 is also perpendicular to the first base 11.

[0084] Furthermore, one end of the first connecting plate 21 extends upward, and one end of the second connecting plate 22 also extends upward synchronously. The upward extending ends of the first connecting plate 21 and the second connecting plate 22 can be provided with other plate members or used to fix other devices to achieve different functions of the transport vehicle. For example, a storage platform can be placed to achieve the material conveying operation of the transport vehicle. Another example is that a fixture can also be provided to achieve the clamping operation of the material during transportation.

[0085] In this embodiment, a first cross beam 23 is provided between the first connecting plate 21 and the second connecting plate 22. The first cross beam 23 makes the first connecting plate 21 and the second connecting plate 22 form an integral whole. Further, a shock absorption assembly 3 is provided on the first cross beam 23. The shock absorption assembly 3 serves as a connection structure between the upper frame assembly 2 and the lower frame assembly 1. Specifically, the shock absorption assembly 3 includes a support rod 32, an adjusting member 31, and an elastic member 33. The number of support rods 32 can be set according to actual needs. One end of the support rod 32 is connected to the first cross beam 23, and the other end of the support rod 32 extends downward. The first base 11 is arranged below the first cross beam 23. An elastic member 33 is sleeved on the rod body of the support rod 32 extending downward. Optionally, the elastic member 33 can be a spring. One end of the elastic member 33 abuts against the lower surface of the first cross beam 23, and the other end of the elastic member 33 abuts against the upper surface of the first base 11. Optionally, an avoidance hole can be provided on the first base 11, and the end of the support rod 32 extending downward can be placed in the avoidance hole. When the first base 11 encounters a raised area during driving, the first base 11 moves upward, and the support rod 32 can move downward in the avoidance hole while compressing the elastic member 33 to maintain the horizontal height of the upper frame assembly 2.

[0086] In this embodiment, one end of the support rod 32 extending upward protrudes out of the upper surface of the first cross beam 23. An adjusting member 31 is provided at the end of the support rod 32 extending upward. The adjusting member 31 can adjust the position of the support rod 32, and further adjust the length of the part of the support rod 32 between the first cross beam 23 and the first base 11. Specifically, by adjusting the length of the support rod 32 protruding upward from the first cross beam 23, the length of the rod body of the end of the support rod 32 extending downward can be realized, that is, the compression degree of the elastic member 33 can be realized. By reasonably adjusting the support rod 32, the elastic member 33 can be in a pre-compressed state under normal conditions and has a certain elastic potential energy. When encountering a sunken road surface, the elastic member 33 can release the pre-stored elastic potential energy in time, thereby reducing the downward movement amplitude of the upper frame assembly 2. Similarly, when encountering a raised road surface, the elastic member 33 can be further compressed to reduce the upward movement amplitude of the upper frame assembly 2, so as to achieve the shock absorption effect of the upper frame assembly 2.

[0087] By arranging the shock absorption assembly 3 between the upper frame assembly 2 and the lower frame assembly 1 as the connection point between the upper frame assembly 2 and the lower frame assembly 1, the elastic property of the elastic member 33 is used to effectively absorb the vibration damping generated during transportation, improving the ability of the entire transport vehicle to transport smoothly on uneven ground. At the same time, the transmission connection form of the first chain group 13 and the first drive unit 14 in the lower frame assembly 1 makes the spatial structure of the entire transport vehicle more miniaturized and lightweight, meeting the transfer requirements in the actual scenario of photovoltaic modules, reducing the manufacturing cost, and improving the adaptability of the entire transport vehicle to the environment.

[0088] Please refer to Figure 4 , in some embodiments, an external thread is provided on the outer surface of the support rod 32, and the support rod 32 is threadedly connected to the first cross beam 23; the adjusting member 31 is a nut, and the nut is threadedly connected to the upwardly protruding end of the support rod 32. In this embodiment, an external thread can be machined on the outer surface of the support rod 32, and an internal threaded hole can be correspondingly machined on the first cross beam 23, so that the support rod 32 can be threadedly connected to the first cross beam 23. Further, by using the nut as the adjusting member 31, it is only necessary to directly sleeved the nut on the end of the support rod 32 protruding above the first cross beam 23, which is convenient for manual adjustment. This method can realize the adjustment of the support rod 32 in the height direction, and further, it can also reduce the manufacturing costs of the support rod 32 and the adjusting member 31, and is easy to disassemble, adjust and install.

[0089] In some embodiments, the number of the support rods 32 is two, the number of the elastic members 33 is also two, one support rod 32 corresponds to one elastic member 33, and the number of the adjusting members 31 can also be two, and one adjusting member 31 corresponds to one support rod 32. By providing a plurality of support rods 32 and elastic members 33, the shock-absorbing connection between the upper frame assembly 2 and the lower frame assembly 1 can be made more stable.

[0090] Please refer to Figure 2 , in some embodiments, the upper frame assembly 2 further includes a second cross beam 24, the second cross beam 24 is disposed between the first connecting plate 21 and the second connecting plate 22, and a first driving unit 14 is provided at the end of the second cross beam 24; the lower frame assembly 1 further includes a first shield 17 and a second shield 18, the first shield 17 is disposed on the second cross beam 24 and is disposed above the first driving unit 14; the second shield 18 is disposed on the second cross beam 24, and the second shield 18 extends downward to cover the outside of the first chain group 13.
