[0031] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0033] In the prior art, the side plates and extensions used in torque arms are mostly curved structures. When producing torque arms, the curved structures need to be bent to a specified arc, which adds a production step of bending, and the quality is difficult to control, so the processing difficulty coefficient is high.

[0039] See also Figure 2 and Figure 3 The torque arm 1 includes a rib plate 11 , a cover plate 12 , a bottom sealing plate 13 , a mounting seat 14 , a front side plate 151 , a rear side plate 152 , a left side plate 153 and a right side plate 154 .

[0040] The torque arm rib plate 11 , the cover plate 12 , the bottom sealing plate 13 , the front side plate 151 , the rear side plate 152 , the left side plate 153 and the right side plate 154 together constitute an extension portion 17 . Optionally, three mounting holes are respectively provided on both sides of the mounting seat 14 .

[0041] The inner side of the mounting hole of the mounting seat 14 is composed of four side panels, including: a front side panel 151, a rear side panel 152, a left side panel 153 and a right side panel 154. The four side panels are all straight panels and are spliced ​​together to form a torque arm body 16. Specifically, the left side panel 153 and the right side panel 154 extend toward the reducer, and a semi-enclosed space is formed at the upper and lower parts of the extended portion of the torque arm through the cover plate 12 and the bottom sealing plate 13, respectively. The cover plate 12 and the bottom sealing plate 13 are both straight panels.

[0042] In this embodiment, the cover plate 12, the bottom sealing plate 13, the front side plate 151, the rear side plate 152, the left side plate 153 and the right side plate 154 are all designed by splicing straight plates, which can not only reduce the difficulty of processing and simplify the structure of the torque arm, but also enhance its stability while ensuring the bearing capacity, making the processing process more convenient, improving space utilization, and making the overall structure more compact.

[0043] In other replaceable embodiments, the torque arm in the reducer torque arm structure has two side plates that are relatively set, such as only front and rear side plates, or only left and right side plates; this can reduce the use of materials and simplify the structure.

[0044] The inner space formed by the cover plate 12 and the bottom sealing plate 13 is supported by three rib plates 11. The first rib plate 111 is located at the innermost part and forms a closed space with the four side plates 15. The second rib plate 112 is located in the middle of the three rib plates 11 and is spaced apart from the first rib plate 111 and the third rib plate 113.

[0047] The first pin 321 and the second pin 322 are combined to assemble the reducer 2 on the second pin 322. This installation method has little restriction on the installation structure volume of the reducer 2. In other words, the first pin 321 and the second pin 322 together form a double pin structure, which enables flexible adjustment of the position of the reducer 2 and enhances the bearing capacity and stability of the torque arm 1. In fact, the axis of the torque arm structure and the installation axis of the reducer are misaligned to free up space for easy installation.

[0048] Optionally, see Figure 1 , Figure 3 , Figure 4 A first retaining ring 331 is installed on the outer side of the first connecting plate 311 to limit the first pin shaft 321 . Optionally, the first pin shaft 321 can pivot on the second rib plate 112 and the third rib plate 113 .

[0049] The reducer 2 includes: a reducer body 21 and an arched pivot part 22, the arched pivot part 22 is arranged at the top of the reducer body 21, a mounting hole is arranged in the middle of the arched pivot part 22, and the second pin shaft 322 passes through and is installed in the central mounting hole of the reducer arched pivot part 22.

[0050] Optionally, both ends of the second pin shaft 322 extend beyond the arched pivot portion 22 , the first connecting plate 311 and the second connecting plate 312 are respectively connected to the extending portions of the top end of the second pin shaft 322 , and a second retaining ring 332 is disposed outside the first connecting plate 311 for fixing the second pin shaft 322 .

[0051] By respectively providing the first retaining ring 331 and the second retaining ring 332 at both ends of the first pin shaft 321 and the second pin shaft 322 , the positions of the first pin shaft 321 and the second pin shaft 322 in the mounting hole can be limited, thereby avoiding radial movement and achieving strong stability.

[0052] Optionally, the second pin shaft 322 can be pivoted on the arched pivot portion 22, so as to flexibly adjust the position of the reducer 2 and make replacement of the reducer 2 more convenient.

[0053] See also Figure 1 and Figure 5 In another embodiment of the present application, a trolley frame is provided, comprising: a reducer torque arm 1 and a trolley frame 4 according to any of the above embodiments, wherein the reducer torque arm 1 is arranged on the trolley frame 4;

[0054] In this example, the cover plate 12, bottom sealing plate 13, front side plate 151, rear side plate 152, left side plate 153 and right side plate 154 in the reducer torque arm are all designed by straight plate splicing, which can not only reduce the difficulty of processing and simplify the structure of the torque arm, but also enhance its stability while ensuring the bearing capacity, making the processing process more convenient, making the manufacturing of the entire trolley frame simpler and reducing the production cost.

[0055] Specifically, the reducer torque arm structure includes: a torque arm 1, a reducer 2 and a connecting arm 3. The torque arm 1 is arranged on the top surface of the trolley frame 4, the trolley frame 4 is fixedly connected to the torque arm 1, and the reducer 2 and the connecting arm 3 are suspended on the side of the trolley frame 4, thereby saving the space occupied by the trolley frame 4 as a whole.

[0056] The trolley frame 4 body is provided with a driving wheel 411, a first driven wheel 412 and a second driven wheel 413. The output shaft of the reducer 2 is connected to the driving wheel 411 to drive the driving wheel 411 to rotate, and then the driving wheel 411 drives the first driven wheel 412 and the second driven wheel 413 to move, thereby realizing the overall movement of the trolley frame.

[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom still fall within the scope of protection of the invention of the utility model.
