The invention discloses a carriage bidirectional expansion mechanism which comprises two sets of drawing assemblies, two sets of lifting assemblies and an auxiliary frame, and the drawing assemblies and the lifting assemblies are both integrally installed in the auxiliary frame. Each drawing assembly comprises a drawing motor, the output shaft end of the drawing motor is fixedly connected with a drawing transmission shaft, gears are symmetrically and fixedly installed on the surface of the drawing transmission shaft, a transmission cross beam is slidably installed in the auxiliary frame, a rack is fixedly installed on the bottom surface of the transmission cross beam, and the rack is in transmission connection with the gears. Two sets of drawing motors are arranged on the drawing assembly in the horizontal direction to control two sets of drawing transmission shafts, gears on the surfaces of the drawing transmission shafts are used for driving transmission cross beams, gaps between the transmission cross beams are changed, and therefore the inner space of the compartment is changed; the single-side transmission cross beam is controlled by utilizing an independent drawing motor; and the expansion mechanism can selectively expand the single-direction carriage body and the double-direction carriage body to increase the internal space of the carriage.

    本发明公开了一种车厢双向式扩展机构,包括两组抽拉组件、两组举升组件和副车架,所述抽拉组件、举升组件均集成安装于副车架内;所述抽拉组件包括抽拉电机,所述抽拉电机的输出轴端固定连接有抽拉传动轴,所述抽拉转动轴表面对称其固定安装有齿轮,所述副车架内滑动安装有传动横梁,所述传动横梁底面固定安装有齿条,所述齿条和齿轮传动连接,在水平方向的抽拉组件,分别设置两组抽拉电机控制两组抽拉传动轴,利用抽拉传动轴表面的齿轮驱动传动横梁,改变传动横梁之间间隙,从而改变车厢内部空间,利用单独的抽拉电机控制单边的传动横梁,可以有选择性进行单、双向舱体扩展来增加车厢内部空间的扩展机构。
