Electric gas spring

Abstract

The invention discloses an electric gas spring. The electric gas spring comprises a cylinder pipe, a planetary gear reducer, a nut piston rod, a lead screw, an outer tube, a motor, gas or an oil-gas mixture and guiding, fixing, sealing and circuit components; the motor is arranged on one side of the electric gas spring, the input end of the motor is connected with a circuit board, an electric wire connected to the circuit board is arranged in a wire protecting pipe, and one end of the wire protecting pipe penetrates through a back dustproof boot arranged at the back end of the electric gas spring; the back end of the electric gas spring is provided with a back end connecting part in a connected mode, a back end cover is arranged on the lower side of the dustproof boot arranged at the back end of the electric gas spring, the output end of the motor is connected with the planetary gear reducer, the front end of the electric gas spring is provided with a front end ball head, the outer surface of the front end of the electric gas spring is provided with a front end cover, and the inner surface of the front end of the electric gas spring is provided with a front dustproof boot. The novel electric gas spring is reasonable in structure, wide in using length range, stable in force character property and long in service life and can adapt to support rods with different support force.

Description

technical field [0001] The invention relates to a spring, in particular to an electric gas spring. Background technique [0002] The electric gas spring support rod is mainly composed of a cylinder, a piston in the cylinder, a piston rod, a motor, a planetary reducer, a screw rod, a nut piston rod, a cylinder tube, an outer tube, and various guide fixed seals and circuit components, etc. Nitrogen or oil-gas mixture is stored in the cylinder. Since the piston or piston rod occupies the volume of the cylinder, the cross-sectional area of ​​the piston rod and the nitrogen pressure in the cylinder are used to realize the movement of the piston rod (the cross-sectional area of ​​the piston rod multiplied by the nitrogen pressure is equal to the thrust of the piston rod movement), The force of the gas spring is realized by the forward and reverse rotation of the motor to realize the electric gas spring. However, the currently disclosed electric strut is mainly composed of a mech...

AI Technical Summary

Problems solved by technology

In the electric support rod disclosed at present, the power source for the extension of the piston rod is generated by a mechanical spring. Because the force value of the mechanical spring is difficult to guarantee, the elastic life is unstable, the compression limit of the length of the mechanical spring is not ideal, and other performances are inferior to those of the pneumatic spring. The finished product does not achieve a more ideal effect
