Abstract

The invention discloses a push rod device for switching power for an electric automobile. The push rod device comprises a shell and a lockable air spring, wherein the axis of the lockable air spring extends along the forward-backward direction; the tail end of a piston rod of the air spring is hinged to the shell; the tail end of an air spring cylinder extends forwards out of the shell to form a force application end for pushing a battery box; a front support which is matched with a sliding support of the air spring cylinder is arranged in the shell; and the shell is also provided with a control mechanism for controlling opening and closing of an air spring button. Since the air spring is adopted in the shell, the forward-backward stretch of the air spring cylinder is realized under the control effect of the control mechanism, the thrust produced thereby is sufficient to meet the requirements of draw-out of the battery box, and the battery box can be pushed in smoothly even though the battery box is blocked.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to a push rod device for changing battery boxes at an electric vehicle charging station. Background technique [0002] At present, in the electric vehicle charging station of the State Grid, in order to ensure the successful extraction of the battery box, a push rod mechanism is generally used. The thrust of the current push rod mechanism is mainly provided by ordinary mechanical springs. Due to the limitation of structural space, spring processing technology and Influenced by the service life of the mechanical spring, the thrust is generally small, so when the battery box is stuck, it is difficult to push the battery box in, which will cause the failure of battery replacement; in addition, the push rod of this push rod mechanism can only be straight Movement, once the battery box is tilted, it is easy to cause the push rod to be twisted and deformed.
