Description

Technical Field

[0001] The utility model relates to the technical field of electric flat car steering, and more specifically, to an electric flat car steering device. Background Art

[0002] Electric flat cars are vehicles that use batteries as power and motors as drive for transporting goods or people. Electricity is an important energy source that is environmentally friendly, clean, and has a high conversion rate. Using electricity to drive the replacement of vehicles, promote the low-carbon development of the transportation industry, reduce transportation costs, save energy, and protect the environment is one of the important research topics in countries around the world. After decades of development, it has been used in many fields such as urban buses, electric transport vehicles for factories and mines, electric urban sanitation cleaning vehicles, engineering, tunnels, and subway construction special vehicles.

[0003] For example, the patent document with the announcement number CN 212500077 U discloses an electric flat car with a buffer device, including an electric flat car and a buffer platform, a roller is arranged at the bottom of the electric flat car, and connecting bolts are fixedly installed at both ends of the electric flat car. The utility model sets a fixed column, a buffer column, a first spring and a second spring, and moves the buffer column up and down in the buffer cavity inside the fixed column, so that the buffer column squeezes the first spring, squeezes the second spring through the slider, and finally passes the buffer layer for the final buffer protection, which effectively improves the overall buffer effect; by setting a fixed block, a fixed groove, a connecting block and a fastening bolt, the bolt is pulled out from the first fastening hole and the second fastening hole by reversing the fastening bolt, and then the fixed block on the inner side of the connecting block is pulled out from the fixed groove by external force, so that the buffer platform and the electric flat car can be separated, and the disassembly and assembly steps are effectively simplified, thereby improving the work efficiency of maintenance workers.

[0004] However, during the actual steering process of the electric flat cart, the bottom of this structure cannot perform stable steering limit protection operations, which makes it easy for the head and tail to swing when steering too fast, and the electric flat cart cannot be turned more safely and efficiently. At the same time, the equipment cannot properly perform steering protection operations on the items carried on the surface of the electric flat cart, and cannot meet daily use needs. Therefore, in order to solve the above technical problems, this application proposes an electric flat cart steering device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide an electric flat car steering device.

[0006] To achieve the above object, the utility model provides the following technical solution: comprising a flat car body, a main universal joint is arranged at the inner center of the flat car body, an adjustment frame is movably connected to the surface of the flat car body, and a reset rubber sleeve is arranged at the edge between the flat car body and the adjustment frame;

[0007] An annular base, the bottom end of the flat car body is fixedly connected with the annular base, and the bottom end of the annular base is fixedly connected with a shrink ring seat.

[0008] Preferably, a driving unit is disposed at the inner center of the annular base, and driving wheels are disposed at the four bottom corners of the driving unit.

[0009] Preferably, connecting blocks are fixedly connected to the four corners of the side surfaces of the driving unit.

[0010] Preferably, a shrinkage groove is provided inside the shrinkage ring seat, and a ground-contacting ring airbag is provided inside the shrinkage groove.

[0011] Preferably, a gyroscope is arranged at the inner center of the adjusting frame, and a limiting rubber ring is arranged at the surface edge of the adjusting frame.

[0012] Preferably, electric push rods are arranged on the four inner sides of the flat car body, and a secondary universal joint is arranged at one end of the electric push rods.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, a more efficient and stable overall turning and using operation of the flat car body can be realized through the flat car body, the annular base, the shrinking ring seat, the driving unit, the driving wheel, the connecting block, the shrinking groove and the ground-contacting ring airbag. In the actual use process, the staff first places the articles to be transported on the surface of the adjusting frame. At this time, the driving unit and the driving wheel at the bottom of the flat car body are started to drive the adjusting frame and the articles as a whole to move and transport. During the transportation process, when the flat car body needs to be turned through the driving unit and the driving wheel, the flat car body as a whole will be tilted and adjusted as a whole under the action of centrifugal force during the turning process. At the same time, the annular base as a whole is also adjusted with the flat car body. At this time, the ground-contacting ring airbag inside the shrinking ring seat at the bottom of the annular base can be adaptively contracted and adjusted inside the shrinking groove, thereby ensuring that the driving unit around the flat car body can always be stably supported and protected when the flat car body is turned and centrifugally swung, avoiding the occurrence of dumping problems, improving the overall stability of the equipment, and reflecting the practicality of the equipment design.

[0015] 2. In the utility model, the overall use effect of the equipment is further improved through the flat car body, main universal joint, adjustment frame, reset rubber sleeve, gyroscope, limit rubber ring, electric push rod and auxiliary universal joint. In daily use, when the flat car body as a whole turns and tilts, the adjustment frame and the items carried on the surface will also tilt with the flat car body. At this time, the gyroscope at the center of the adjustment frame can be monitored at the first time, and then the electric push rods and auxiliary universal joints on the four sides of the flat car body are adaptively started, so that the adjustment frame can perform rapid adaptive correction and adjustment operations around the main universal joint at the center of the flat car body. At the same time, the reset rubber sleeve between the flat car body and the adjustment frame can always ensure stable reset stretching adjustment operations, which greatly improves the steering stability of the overall equipment carrying items and reflects the comprehensiveness of the equipment design.
