Description
Technical field
The invention belongs to automobile tail gate strut technical fields, relate more specifically to a kind of automobile power back door strut.
Background technique
Background of related of the invention is illustrated below, but these explanations might not constitute it is of the invention existing
Technology.
Tail door supporting rod is the important component that automobile tail gate opens and closes, and mostly uses electric tail gate to set in superior automobile
Meter is opened and is withdrawn by motor control strut and realizes opening and closing automatically for automobile tail gate.
Existing automobile tail gate generallys use unilateral strut, the design of other side pneumatic spring or spring, to ensure tail
Stress balance when door is opened, the work of single strut not can guarantee two sides simultaneously in place, or the position disunity of arrival, cause tail-gate
Torsional deformation causes tail-gate to be closed not tight, tail-gate leak can occur when rainy；If not sharing a signal source, two side braces
It is difficult to accomplish to synchronize.
It can open and withdraw along with strut when opening and closing using the automobile tail gate of electric tail gate strut and generate
Noise.
In addition, the structure of traditional strut sets unreasonable, the limit of the interior bar of strut is unreasonable, is easy pop-up, and inside and outside
Rotation design is not put between pipe, inner tube can occur present relative to outer tube when use.
Importantly, there is no anti-lock design between traditional strut and motor, i.e., when external force leads to strut locking,
The case where motor still rotates causes motor damage next time.

In conclusion the invention has the following advantages that
1. the electronic pole structure in tail-gate two sides is identical, two side braces share the same signal source, and controller controls two sides
Strut works at the same time.Guarantee that tail-gate two sides simultaneously close off and open.It will not cause to deform because of tail-gate discontinuity.Single strut
Work not can guarantee two 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 are also difficult to accomplish to synchronize.
2. the first outer tube 5 and the second outer tube 6 use guide barrel construction, guiding role is played, it is important that the first outer tube 5 and the
Biggish relative rotation will not be generated between two outer tubes 6.
1) when motor drives screw mandrel 10 rotates, feed screw nut 12 has the tendency that rotation, but feed screw nut 12 and silk at this time
Rod set bar 11 is riveted together, and screw rod loop bar 11 is riveted with inner end cap 8a riveting, outer end cap 8b and the second outer tube 6 again.Work as screw rod
When 10 rotation, rotary force is transmitted to the first outer tube 5 by feed screw nut 12, silk braid loop bar, end inner end cap 8a, outer end cap 8b
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 in a straight line on the first outer tube 5.Therefore work as
When motor rotates, feed screw nut 12 can only move in a straight line on screw rod 10, to realize that strut is opened and withdrawal acts.
2) from the above, the second outer tube 6 can only move in a straight line on the first outer tube 5, if fit clearance is smaller, rotation
The opposite sliding in direction is with regard to very little.After strut fills onboard, the first bulb 1 is connected with the ball head column of vehicle body ironware, works as deceleration
When motor 3 rotates, the rotary force of motor is applied on the first bulb 1 and ball head column by the first outer tube 5, but because of 5 phase of the first outer tube
To sliding less, the case where only one end stress will not be generated, but power is applied to both ends simultaneously substantially.Guarantee that strut is not easy
It falls off from car body.
3. inside screw rod 10 straight cutting to gearbox 4, using spline fitted, less intermediate connecting part guarantees to have preferable
Concentricity.It rubs between components less, thus it is smaller to generate opposite noise
4. crucial portion adds riveted structure using screw thread, and screw thread prevents push-pull effort, and riveting is anti-because there is brute spring inside strut
Spin-ended turn, riveting also has certain stretching resistance, so that strut will not answer 14 elastic force of spring and flick, strut is caused to fail or send out
It is raw dangerous.
5. the fixed form of screw rod 10 and fixing sleeve 9 is fixed using 15 structure of bearing shell.Pulling force suffered by bearing shell 15 is strength bullet
The elastic force that spring 14 is given, bearing shell 15 can the larger pulling force of bearing capacity (about 6800N), 10 end face of screw rod can bear maximum, force be 2200N,
, considerably beyond the maximum elastic force (14 maximum elastic force 800N of spring) of spring 14, strut is not easy to flick for it！
6. waterproof construction designs, external waterproof apron, inside is filled up through 27 part sealant 29 of conducting wire, guarantees strut
Motor will not fail because of leak.
Although referring to illustrative embodiments, invention has been described, but it is to be understood that the present invention does not limit to
The specific embodiment that Yu Wenzhong is described in detail and shows, without departing from claims limited range, this
Field technical staff can make various improvement or modification to the illustrative embodiments.
