Gas spring is often used as the important component of tail-gate opening and closing on automobile；A kind of existing automobile gas spring, the Automobile air bullet
Spring includes the lower outer pipe provided with motor and the upper exterior tube being set in outside the lower outer pipe.This automobile gas spring is deposited in use
In following problem：1st, because the structure of lower outer pipe and upper exterior tube sets unreasonable, phenomenon is easily rotated between upper lower outer pipe；2、
And easily occur phenomenon during locking between screw mandrel and motor, so as to cause motor damage.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of automobile gas spring, to solve under existing automobile gas spring
The problem of upper exterior tube easily rotates.
The technical proposal for solving the technical problem of the invention is：This automobile gas spring is provided with upper bulb including one end
Upper exterior tube and one end be provided with the lower outer pipe of lower bulb, be installed with motor in the lower outer pipe；Edge is arranged with outside the lower outer pipe
The upper exterior tube of lower outer pipe axis direction motion, the motor are connected with screw mandrel by gearbox, the screw mandrel with it is described
Fixed cover is provided between gearbox, the fixed cover is fixed on the lower outer pipe；Feed screw nut is arranged with the screw mandrel,
Screw rod bushing is provided with the feed screw nut, one end of the screw rod bushing is connected by upper end cover with the upper bulb；Described
Screw rod bushing is externally provided with conduit, and the conduit is provided with the location division abutted against with the upper end cover；Bullet is arranged with the conduit
Spring, one end of the spring abut against with the fixed cover, and the location division of the other end of the spring and the conduit abuts against；
The fixed cover is halved together with the lower outer pipe, and one end of the lower outer pipe is halved together with the upper end cover, the lower outer pipe in
Multiple axial projection sections are circumferentially distributed with the outer wall of the nearly upper end cover termination, the upper exterior tube is in provided with multiple in inwall
Circle distribution and the guide groove that is engaged with multiple axial projections.
In above-mentioned automobile gas spring technical scheme, more specifically technical scheme can also be：The extension of the screw mandrel is worn
Cross the fixed cover to be connected with the gearbox, bearing is provided between the extension and the fixed cover of the screw mandrel, it is described
Bearing is sleeved on by axle sleeve on the extension of the screw mandrel.
Further：The extension of the screw mandrel is connected by spline with the gearbox.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：1. due under
Outer tube in being circumferentially distributed with multiple axial projection sections on the outer wall of nearly upper end cover side, upper exterior tube in inwall be provided with it is multiple circumferentially
The guide groove being engaged with multiple axial projections of distribution, both are mutually oriented to, limited, and phase will not occur for upper exterior tube and lower outer pipe
To rotation phenomenon；2nd, the extension of screw mandrel is directly extended inside reductor, and guarantee has preferable concentricity, eliminates motor damage
Hidden danger.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described：
