The invention discloses a lead screw lifting mechanism. The mechanism comprises a motor, a housing, a motor connector, a gas spring assembly, a lead screw assembly and a transmission assembly, whereinthe lead screw assembly consists of a primary lead screw, a secondary lead screw and a tertiary lead screw; the upper end of the lead screw assembly is fixed and the lower end of the lead screw assembly is connected to the transmission assembly which is driven by a motor; the transmission assembly and the motor are fixed through the motor connector; and the gas spring is fixedly arranged inside the lead screw assembly. In this way, the lead screw lifting mechanism adopts a tertiary lead screw mechanism to lift, so that height of the lead screw lifting mechanism is greatly reduced at a fixed stroke height; and the gas spring assembly is quickly lifted by a pull force auxiliary lead screw mechanism thereof, so that time is saved and power needed for motor drive is reduced.
本发明公开了一种丝杠升降机构,所述机构包括电机、外壳、电机连接器、气弹簧组件、丝杠组件和传动组件;所述丝杠组件由一级丝杠、二级丝杠和三级丝杠组成,所述丝杠组件上端固定,下端与传动组件连接,所述传动组件由电机驱动,所述传动组件和所述电机通过电机连接器固定;所述气弹簧组件固定在丝杠组件内部。通过上述方式,本发明采用三级丝杠机构实现升降,在行程高度固定的情况下大大减小了丝杠升降机构的自身高度;采用气弹簧组件,通过其自身的拉力辅助丝杠机构快速升降,节省时间,降低电机驱动所需功率。
