Title:
ELECTRICALLY-DRIVEN GAS SPRING
Document Type and Number:
WIPO Patent Application WO/2018/058520
Kind Code:
A1
Abstract:
Disclosed is an electrically-driven gas spring. The electrically-driven gas spring comprises a sleeve (100), a driving device (200), a screw rod (300), a transmission device (400), a piston rod (500), and a seal structure (600). The driving device (200) is located at one side of the end portion of the sleeve (100). The screw rod (300) is fixed on the driving device (200), is located in the sleeve (100) and is driven by the driving device (200) to rotate. The transmission device (400) is connected to the screw rod (300) in a sleeved manner. The piston rod (500) is sleeved on the screw rod (300), is connected to the transmission (400), and is driven by the transmission device (400) to stretch and retract at the other end of the sleeve (100). The seal structure (600) is disposed at the end portion of the sleeve (100) and is used for sealing. The sleeve (100) is filled with high-pressure gas. According to the electrically-driven gas spring, a rotating motor (21) and a screw rod transmission device (400) are both disposed in the sleeve (100), and the sleeve (100) is filled with the high-pressure gas; the electrically-driven gas spring has a simple integral structure and a small size, and is convenient to mount; stable output power can be provided by adjusting the power of the rotating motor (21); and the driving capability is flexible and adjustable.
