Description
Technical field
It the utility model is related to a kind of tail door supporting rod for being used to switch three box car boot tail-gate.
Background technology
The tail-gate of three box car automobile is often by the use of gas spring as branch stake tool, when opening tail-gate manually or electric control pine
Tail-gate lock is opened, so that gas spring props up tail-gate, need to be caused high effort for when closing tail-gate with tail-gate under hand pressure, shutdown.For convenience
The switch of tail-gate, user can dismantle gas spring after car is bought and install tail door supporting rod, but existing electric tail gate strut is more
For L-shaped, motor is located at screw mandrel radial side, and radially this electric tail gate strut needs to carry out the drilling of tail-gate, can damage former car knot
Structure.
When opening, in the front half section that tail-gate is opened, due to the presence of tail-door hinge mechanism, motor needs to apply sedan tail door
Add larger power so that tail-gate is opened, motor heavy load, service life can shorten.Tail-gate when closed, the dead bolt of tail-gate with
Certain resistance during the snap fit of tail-door hinge mechanism be present, tail-gate is difficult to completely close, car tail-gate meeting in the process of moving
Rock to produce noise.
The content of the invention
The purpose of this utility model is to provide a kind of linear electric tail gate support of automobile trunk suitable for three box car
Bar.
To achieve the above object, the utility model adopts the following technical scheme that：A kind of linear electronic tail of automobile trunk
Portal bracing bar, including the reducing motor being arranged in electric machine casing, output shaft and the screw mandrel of the reducing motor are coaxially disposed, described
Screw mandrel is arranged in conduit, and the conduit is relatively fixed with electric machine casing, is provided with push pipe in the conduit, screw thread on the screw mandrel
Feed screw nut is combined with, the push pipe is fixed with the feed screw nut and push pipe is set in outside screw mandrel, one end of the screw mandrel
Linked for linkage end and with the output shaft of reducing motor, reducing motor is operated so that the push pipe does reciprocal fortune along screw mandrel axis
Dynamic, the catheter jacket is provided with extension spring, and the one end of the push pipe away from feed screw nut is fixed with spring base, and the conduit leans on
One end of nearly reducing motor is fixed with conduit gland, and spring base and the conduit gland is each formed with and the extension spring
The helicitic texture being engaged, the both ends of the extension spring fix head thread with spring base and conduit respectively and coordinate fixation.
The tail door supporting rod that reducing motor is coaxially disposed with screw mandrel, is arranged at compared with motor for the tail door supporting rod of screw mandrel radial side
Space-consuming is smaller, the installation site of original gas spring can be used to carry out the installation of the utility model tail door supporting rod, it is not necessary to
Tail-gate or interior of body are drilled, vehicle body will not be caused to damage, be easy to the installation of the utility model tail door supporting rod.This reality
With new by setting extension spring outside conduit, while reducing motor output shaft is coaxially disposed with screw mandrel, so that tail door supporting rod
Effect is more preferable during stretching, more laborsaving when can operate motor, and it is of the present utility model to reduce that the smaller motor of power may be selected
Production cost, or make sedan tail door more convenient when closed in the case where selecting the motor of former power.
