The invention discloses a rollator, which belongs to the field of rehabilitation rollator equipment and comprises a transmission mechanism, the transmission mechanism comprises a driving wheel, a driven wheel and a chain, the driving wheel and the driven wheel are rotatably mounted on a fixed chassis, the chain is mounted between the driving wheel and the driven wheel, and the chain is fixedly connected with a movable chassis. The driving piece drives the lifting mechanism to rotate relative to the machine frame to enable the posture of the rollator to change, the lifting mechanism drives the chain through the driving wheel, and the chain drives the movable chassis to move relative to the fixed chassis to enable the length of the telescopic chassis to be synchronously adjusted along with the posture change of the rollator. Backward inclination is prevented; and when a person stands up, the telescopic chassis is shortened, so that the maximum flexibility of the vehicle body during movement is ensured. The invention further relates to the telescopic chassis.
本发明公开了一种助行车,属于康复助行设备领域,包括传动机构,传动机构包括主动轮、从动轮以及链条,主动轮以及从动轮转动安装于固定底盘,链条安装于主动轮以及从动轮之间,链条与活动底盘固定连接,驱动件带动举升机构相对机架转动使助行车姿态变化,举升机构通过主动轮带动链条,链条带动活动底盘相对固定底盘移动使伸缩底盘的长度随助行车姿态变化同步调整,当人坐下时,伸缩底盘变长,保证用户重心落在伸缩底盘内,防止后倾;当人站立起来时,伸缩底盘收短,保证车体运动时的最大灵活性。本申请还涉及上述伸缩底盘。
