A trolley and a road contact power supply device in cooperative use with the trolley belong to the field of transportation. The trolley has a current collector mounted at a lower part thereof to receive power from a contact power supply device mounted on road surface. The current collector is composed of a contact slide plate (1), a first bent connecting rod (11) and a second bent connecting rod (16), where a flat thin strong magnet (5) is arranged on the contact slide plate (1). The road contact power supply device in cooperative use with the vehicle has a cable (32), a contact (46), a compression spring (26), an elastic sealing sleeve (34), a seal tube (38), a seal housing (39), a movable contact (41) and a fixed contact (49), where an upper end of the movable contact (41) is connected to a lantern ring (43) made of a ferromagnetic material, and an upper end of the lantern ring (43) is close to an upper surface of the contact (46). The contact power supply device has ultrahigh supply power, desirable universality, relatively low cost, ensured safety, and long service life. The device can be easily automatically produced, mounted and maintained and thus used for a long time on a large scale.
