Abstract

The invention discloses an electric vehicle trolley battery box with automatically retractable wheels, which includes a battery box main body 1, a tie rod mechanism, a connecting rod mechanism, a steering mechanism, and wheels 11. A vertical slide rail 5 is fixed on the front of the battery box main body 1. , the pull rod mechanism is nested in the vertical slide rail 5 and can slide along the vertical slide rail 5. One end of the linkage mechanism is rotatably connected to the lower end of the pull rod mechanism, and the other end is rotatably connected to the steering mechanism. The steering mechanism is rotatably connected to the wheels. , when the pull rod mechanism is pulled, the pull rod mechanism drives the connecting rod mechanism, the steering mechanism, and the wheels 11 to realize the automatic retraction of the wheels 11. The battery case of the present invention occupies less space, and is more convenient and 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 ...
