Realize the control to opening/closing door of vehicle.In the prior art, when electric pushrod inner tube, which reaches maximum rating, to be stood, due to compressing bullet
Spring can not share tail-gate weight completely, and screw mandrel static state damping force diminishes, causes tail-gate to fall automatically and be even switched off, and this can be to electronic
Push rod is impacted and destroyed in itself, influences push rod normal use performance, shortens product service life, so as to influence vehicle
Energy.
The content of the invention
In view of the above-mentioned problems, providing a kind of automobile tail gate electric pushrod damping structure, the structure can be reduced into the present invention
This, easy to assembly, and the static damping of screw mandrel can be effectively increased, screw mandrel static resistance when avoiding the electric pushrod from being opened to maximum rating
Buddhist nun's deficiency causes push rod to be impacted, and increases product service life, it is ensured that push rod is safely and smoothly run, and feels driver and crew
By more good comfortableness.
According to technical scheme：A kind of automobile tail gate electric pushrod damping structure, it is characterised in that：Including outer
Manage, guide pipe is equipped with outer tube, be oriented to the dynamic setting screw mandrel of pipe orifice transfer, the output end of screw mandrel is connected with connector one end
Connect, the connector other end is connected with the output shaft set in outer tube, the screw mandrel, connector, output shaft synchronous motion, connection
The circumferential surface of part is arranged friction plate, and friction plate and connector synchronization action, the both sides of friction plate set a pad, padded respectively
It is connected on the outside of piece with the inside of guide pipe by spline fitted, guide pipe is provided with end cap in the inner chamber of output shaft one end, output
Axle one end diameter of axle that is connected with connector is provided with spring, and spring one end is pressed on end cap, and the spring other end is pressed in adjacent
On near pad.
As a further improvement on the present invention, the screw mandrel connection end passes through D word shapes structure and connector respective end
Stopper slot is connected.
As a further improvement on the present invention, the output shaft connection end passes through D word shapes structure and connector respective end
Stopper slot be connected.
As a further improvement on the present invention, the friction plate is connected with connector by spline.
As a further improvement on the present invention, the end cap is plastic material, the button point on the outside of end cap with the inside of guide pipe
Junction be connected.
The technical effects of the invention are that：Product of the present invention is used cooperatively using stage clip and friction plate, can be effectively increased
The static damping of screw mandrel prevents tail-gate from falling；Friction plate uses powder metallurgy material, has good antifriction characteristic, ensures that product makes
Use the life-span；The damping structure is simple, compact, safe and reliable.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1, including screw mandrel 1, connector 2, pad 3, friction plate 4, spring 5, end cap 6, output shaft 7, guide pipe 8 etc..
As shown in figure 1, the present invention is a kind of automobile tail gate electric pushrod damping structure, including outer tube, coordinates in outer tube and set
Guide pipe 8 is put, is rotated in the endoporus of guide pipe 8 and screw mandrel 1 is set, the output end of screw mandrel 1 is connected with the one end of connector 2, connector 2
The other end is connected with the output shaft 7 set in outer tube, and the screw mandrel 1, connector 2, output shaft 7 are synchronized with the movement, connector 2
Circumferential surface is arranged friction plate 4, and friction plate 4 and the synchronization action of connector 2, the both sides of friction plate 4 set a pad 3 respectively,
The outside of pad 3 is connected with the inner side of guide pipe 8 by spline fitted, and guide pipe 8 is provided with end cap in one end inner chamber of output shaft 7
6, one end diameter of axle that is connected with connector 2 of output shaft 7 is provided with spring 5, and the one end of spring 5 is pressed on end cap 6, and spring 5 is another
End is pressed on adjoining pad 3.
The connection end of screw mandrel 1 is connected by the stopper slot of D word shapes structure and the respective end of connector 2.
The connection end of output shaft 7 is connected by the stopper slot of D word shapes structure and the respective end of connector 2.
Friction plate 4 is connected with connector 2 by spline.
