It rises, planetary reduction box is connected with the lead screw in the electronic strut of vehicle tail door by link block, outside the planetary reduction box
Several limit raised lines are provided on wall circumferential surface, the inner wall of the electronic strut outer tube is correspondingly provided with several limiting grooves,
Limiting groove can firmly clamp limit raised line.
As a further improvement of the utility model, 2 are evenly arranged on the outer wall circumferential surface of the planetary reduction box
The inner wall of a symmetrical limit raised line, the electronic strut outer tube is correspondingly provided with 2 symmetrical limiting grooves.
The outer tube wall and limiting groove injection molding have certain outward respectively as a further improvement of the utility model,
Drafting angle, while limiting raised line and being equipped with chamfering and drafting angle.
The lead screw being slidably matched with guiding inside pipe wall is arranged on the lead screw as a further improvement of the utility model,
Nut, conduit and feed screw nut's riveting, conduit are arranged in guide pipe.
The electronic strut decelerating motor rotation stop device of the vehicle tail door is equipped with pressure as a further improvement of the utility model,
Contracting spring, compressed spring are up and down in spring guide.
The utility model has the following advantages：
1, riveting can be overcome to be easy the defect loosened using the rotation stop fixed structure of limit raised line and limiting groove, improved
The stability of strut system entirety；
2, use will limit raised line and be arranged on the outer wall of planetary reduction box, can make planetary reduction box will not be relative to electricity
Dynamic strut rotates, and further increases the stability of strut system；
3, it is provided with drafting angle on the limit raised line on 4 circumference of limiting groove 6 and planetary reduction box on 7 inner wall of outer tube
Be conducive to the assembly of the limit raised line 5 and the limiting groove 6 on 7 inner wall of outer tube on 4 circumference of planetary reduction box；
So that electronic strut is not will produce larger vibrations and displacement 4. feed screw nut rotates in guide pipe, increases on strut
Under actively smooth degree.
