Description

Technical Field

[0001] The utility model relates to the field of logistics automatic transportation, in particular to an EMS driving unit device with side non-contact power supply. Background Technique

[0002] With the changes in the production and operation modes of modern enterprises and the external market conditions, the space for reducing product costs by reducing raw material costs and conducting product technology development is getting smaller and smaller. The traditional self-sufficient logistics service cannot compare with professional third-party logistics enterprises in terms of economic benefits, systematization, and specialization. This has led more and more enterprises to outsource logistics operations that do not belong to the core competitiveness of the enterprise in order to optimize enterprise resource allocation and enhance market competitiveness, promoting the rapid development of the Chinese third-party logistics.

[0003] At present, in the power supply mode of transport trolleys, non-contact power supply is adopted. However, since the transport trolley may jolt or vibrate when moving on the track, in order to avoid collisions between the current collector for realizing non-contact power supply and the cable support, it is necessary to set limits on both the upper and lower sides and the left and right sides of the trolley and the track. This results in a rigid collision between the track and the limiting mechanism when jolting occurs. Therefore, it is necessary to improve such a structure to overcome the above defects.
