Abstract

The invention discloses an automobile gas spring, which comprises an upper outer tube with an upper ball head at one end and a lower outer tube with a lower ball head at one end, a motor is fixed inside the lower outer tube; the motor is connected with a screw rod through a gearbox, A fixed sleeve is provided between the screw rod and the gearbox; a screw nut is set on the screw rod, a screw sleeve is provided on the screw nut, and one end of the screw sleeve is connected with the upper ball head through the upper end cover; There is a conduit outside the screw sleeve, and the conduit is provided with a positioning part that abuts against the upper end cover; a spring is sleeved on the conduit; the fixed sleeve is embedded with the lower outer tube, and one end of the lower outer tube is embedded with the upper end cover. The outer wall of the lower outer tube near the end of the upper end cover is circumferentially distributed with a plurality of axial protrusions, and the inner wall of the upper outer tube is provided with a plurality of guide grooves which are circumferentially distributed and cooperate with the plurality of axial protrusions . Compared with the prior art, the present invention can solve the problem that the lower and upper outer tubes of the existing automobile gas spring are prone to rotation.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a gas spring used for a tailgate. Background technique [0002] Gas spring is an industrial accessory that can support, buffer, brake, height adjust and angle adjust; gas spring is often used as an important part of tailgate opening and closing in automobiles; there is a kind of automobile gas spring, the automobile The gas spring includes a lower outer tube provided with a motor and an upper outer tube sleeved outside the lower outer tube. This kind of automobile gas spring has the following problems in the use process: 1. Due to the unreasonable structure of the lower outer tube and the upper outer tube, rotation between the upper and lower outer tubes is easy to occur; 2. It is easy to appear between the screw rod and the motor The phenomenon of locking will cause damage to the motor. Contents of the invention [0003] The technical problem to be solved by...
