Technical field
The utility model is related to a kind of connection header structures of automobile power back door strut, belong to auto parts and components technology neck
Domain.
Background technology
With economic development, living standard is constantly improving, and people in automobile boot tail-gate field to requiring also to exist
Continuous to improve, electric tail gate is increasingly liked by people, and electric tail gate fulfils assignment by internal electronic strut, electronic
The strut prior art can be such that tail-gate stops in any angle, rely primarily on the anti-electricity of the reaction force and direct current generator in spring
Kinetic potential, the power of the two can offset the component of tail-gate gravity, allow tail-gate to complete to stop in any angle, will not fall.But
It is that large-scale SUV struts are relied solely in the reaction force of spring and the counter electromotive force of direct current generator is difficult to make tail-gate arbitrary
Angle stops.
