The invention discloses an electric vehicle draw bar battery box with wheels capable of being automatically taken up and released. The electric vehicle draw bar battery box comprises a battery box main body 1, a draw bar mechanism, a connecting rod mechanism, a steering mechanism and the wheels 11; a vertical sliding rail 5 is fixed on the front side of the battery box main body 1; the draw bar mechanism is embedded in the vertical sliding rail 5 and can slide along the vertical sliding rail 5; one end of the connecting rod mechanism is rotatably connected with the lower end of the draw bar mechanism, and the other end of the connecting rod mechanism is rotatably connected with the steering mechanism; the steering mechanism is rotatably connected with the wheels; and when the draw bar mechanism is pulled, the draw bar mechanism drives the connecting rod mechanism, the steering mechanism and the wheels 11 so as to implement automatic taking-up and release of the wheels 11. The battery box disclosed by the invention occupies a small space and is more convenient, rapider and more labor-saving to move.
Description
technical field [0001] The invention relates to the technical field of electric bicycle battery boxes, in particular to an electric vehicle trolley battery box with automatically retractable wheels. Background technique [0002] Existing electric bicycles are powered by batteries, usually electric bicycles need 4 lead-acid batteries connected in series to supply power, in order to facilitate charging, 4 batteries are often installed in the battery box, the battery box is generally designed to be detachable, it can be removed from the electric bicycle Detach it from the top to carry it to the charging station for charging. At present, most of the upper parts of the battery box are designed with handles, which can be carried and moved by hand. The weight of a single electric bicycle battery is generally 4.5kg, and the total weight of 4 batteries is 18kg. Adding the weight of the battery box, the battery box with the battery weighs about 20kg. It is laborious and inconvenient ...
