1. A battery quick-change system for an electric passenger car chassis, comprising:
a battery changing platform; a quick-change robot; and a charging rack, wherein:
the battery changing platform is collinear with the quick-change robot and the charging rack in an X-direction extending horizontally;the quick-change robot comprises a battery tray and a Cartesian coordinate robot with four degrees of freedom,the Cartesian coordinate robot comprises an X-axis linear positioning system, a Z-axis up-down platform, a Y-axis telescopic platform and a R-axis angle correction system,the X-axis linear positioning system comprises an X-axis two-track rack that enables movement in the X-axis direction, the Z-axis up-down platform comprises a Z-axis two-track rack and a Y-axis two-track rack, and the R-axis angle correction system comprises an R-axis driving motor,two ends of the X-axis two-track rack extend in the X-axis direction to the battery changing platform and charging rack, respectively,the Z-axis two-track rack is connected with the X-axis two-track rack and moves vertically in a Z-axis direction,the Y-axis two-track rack moves horizontally in a Y-axis direction that is perpendicular to the X-axis direction,the Y-axis two-track rack is mounted on the Z-axis two-track rack,each two-track rack has two parallel running tracks over which a part of the Cartesian coordinate robot moves,the battery tray is connected with the R-axis driving motor,an X-axis driving motor is provided on the X-axis two-track rack, a Y-axis driving motor is provided on the Y-axis two-track rack, a Z-axis up-down motor is provided on the Z-axis two-track rack, and the R-axis driving motor is provided on the Y-axis two-track rack,each of the X-axis driving motor, Y-axis driving motor, Z-axis up-down motor and R-axis driving motor is connected with a corresponding encoder, and each of the encoders is connected to a corresponding driver,the battery tray is equipped with a distance measuring sensor,a limit switch is installed on each end of each two-track rack,each driver, each limit switch and the distance measuring sensor are connected with a control system,the X-axis driving motor and the Z-axis up-down motor move in a linked manner,the Y axis-driving motor drives only once the X-axis driving motor and the Z-axis up-down motor reach a set position, andthe R-axis driving motor drives only once the Y-axis driving motor moves to a specified position. |
