Abstract: A power switching circuit receives a first power, a second power and a switching signal, and generates an output power. The power switching circuit includes a first power path and a second power path. The first power path is connected with the first power. The second power path is connected with the second power. When the switching signal in a logic high level, the first power path is in a conducting state and the second power path is in a non-conducting state. Consequently, the first power is selected as the output power by the power switching circuit. When the switching signal in a logic low level, the first power path is in the non-conducting state and the second power path is in the conducting state. Consequently, the second power is selected as the output power by the power switching circuit.

Abstract: Disclosed is a trolley baseplate including a plate body having a head end and a tail end, a first locking mechanism on the plate body adjacent to the head end and a second locking mechanism on the plate body adjacent to the tail end. The second locking mechanism is placed corresponding to the first locking mechanism and the structures of the two locking mechanism are fitting. When front and back trolleys are concatenated, the tail end of the front trolley and the head end of the back trolley can be locked to each other by means of the first locking mechanism and the second locking mechanism. The trolleys with the above structures can be concatenated more conveniently, and are not liable to overturn upon sudden braking or turning, which can effectively shorten the time for the staff to fasten two trolleys together.
