In sum, the present invention has advantages below：
1. the electronic pole structure in tail-gate both sides is identical, and two side braces share same signal source, controller control both sides
Strut works simultaneously.Ensure that tail-gate both sides simultaneously close off and open.Deformation will not be caused because of tail-gate discontinuity.Single strut
Work cannot ensure both sides simultaneously in place, or reach position disunity, cause tail-gate torsional deformation, cause tail-gate closing not
Tightly, tail-gate leak can occur when rainy；If not sharing a signal source, two side braces also are difficult to accomplish synchronization.
2. the first outer tube 5 and the second outer tube 6 use guide barrel construction, play guide effect, it is important that the first outer tube 5 and
Larger rotating against will not be produced between two outer tubes 6.
1) when motor drives screw mandrel 10 to rotate, now feed screw nut 12 has the trend of rotation, but feed screw nut 12 and silk
Rod set bar 11 is riveted together, and screw mandrel loop bar 11 is riveted with inner end cap 8a again, and outer end cap 8b is riveted with the second outer tube 6.Work as screw mandrel
10 when rotating, by revolving force by feed screw nut 12, silk braid loop bar, hold inner end cap 8a, outer end cap 8b to be delivered to the first outer tube 5
On, because the first outer tube 5 and the second outer tube 6 are guide barrel constructions, the second outer tube 6 can only move along a straight line on the first outer tube 5.Therefore work as
When motor is rotated, feed screw nut 12 can only move along a straight line on screw mandrel 10, so as to realize that strut is opened and withdrawal action.
2) from the above, the second outer tube 6 can only move along a straight line on the first outer tube 5, if fit clearance is smaller, its rotation
Direction is relative to be slided with regard to very little.After strut is filled onboard, the first bulb 1 is connected with the ball head column of vehicle body ironware, works as deceleration
When motor 3 is rotated, be applied to the revolving force of motor on the first bulb 1 and ball head column by the first outer tube 5, but because of the phase of the first outer tube 5
It is less to sliding, the situation of only one end stress will not be produced, but power is applied to two ends simultaneously substantially.Ensure that strut is difficult
Come off from car body.
3. the straight cutting of screw mandrel 10 is to inside gearbox 4, using spline fitted, less intermediate connecting part, it is ensured that with preferable
Concentricity.Rubbed between parts less, thus produce relative noise smaller
4., because there is brute spring inside strut, crucial portion adds riveted structure using screw thread, and screw thread prevents push-pull effort, and riveting is anti-
Spin-ended turn, riveting also has certain stretching resistance, so that strut will not answer the elastic force of spring 14 and flick, causes strut to fail or send out
It is raw dangerous.
5. the fixed form of screw mandrel 10 and fixed cover 9 is fixed using the structure of bearing shell 15.Pulling force suffered by bearing shell 15 is strength bullet
The elastic force that spring 14 gives, bearing shell 15 can the larger pulling force of bearing capacity (about 6800N), the end face of screw mandrel 10 can bear maximum, force for 2200N,
, considerably beyond the maximum elastic force (maximum of spring 14 elastic force 800N) of spring 14, strut is difficult to flick for it！
6. waterproof construction design, outside waterproof apron, inside is filled up through the part fluid sealant 29 of wire 27, it is ensured that strut
Motor will not fail because of leak.
Although with reference to illustrative embodiments, invention has been described, but it is to be understood that the invention is not limited in text
Middle detailed description and the specific embodiment for showing, in the case of without departing from claims limited range, this area
Technical staff can make various improvement or modification to the illustrative embodiments.
