It please refers to shown in attached Fig. 1 to Fig. 4, in embodiments of the present invention, a kind of electric driven propelling rod is provided, including driving group
Part 10, silk braid cylinder 20 and flexible cylinder 30 and compression piece 22.The silk braid cylinder 20 is connected to the end of the drive component 10, and
And the silk braid cylinder 20 can be rotated with the driving effect of the drive component 10, which can be with mobile connection at this
In silk braid cylinder 20, and the flexible cylinder 30 can in silk braid 20 rotation of cylinder, relative to 20 telescopic moving of silk braid cylinder, into
And the structure for being connected to flexible 30 end of cylinder can be pushed outwardly or be retracted.The compression piece 22 limiting is connected to silk braid
In cylinder 20.Inner cavity is formed in the silk braid cylinder 20, the cavity wall of the inner cavity is equipped with the first internal thread 21, and the flexible cylinder 30 is flexible
It is mobile be also associated in the inner cavity, and on one end lateral surface of the flexible cylinder 30 for on 20 inner wall of silk braid cylinder
First external screw thread 33 of the first internal thread 21 cooperation, the other end telescopic moving of the flexible cylinder 30 are connected to the silk braid cylinder 20
Outside.In addition, being formed with a cavity 31 in the flexible cylinder 30, which rotates with the silk braid cylinder 20 and compresses or discharge this
Gas in cavity 31.Design is relative to the driving of traditional screw structure in this way, and due to electric pushrod, need in itself will be certain
The object of quality is propped, and then higher for the diametric requirements of screw part in the screw structure, and then in traditional electric pushrod
It is difficult to reduce the size, and then the scope of application is affected due to screw part itself, while the cost is relatively high for product；
And the structure in the present embodiment, by the first internal thread 21 of setting in silk braid cylinder 20, which connects the first external screw thread outside
33, cooperate support total between the two, and then can realize that electric pushrod is lighter thinner, more so as to adapt to
Application environment in.
The electric driven propelling rod designed above, by the way that silk braid cylinder 20 is connected on the drive component 10, and then silk braid cylinder
20 can rotate, while 20 inner wall of silk braid cylinder is equipped with spiral shell in first with the driving of the drive component 10 and with its axial line
Line 21, when the silk braid cylinder 20 rotates, be connected to flexible cylinder 30 in the silk braid cylinder 20 by the first external screw thread 33 with this
One internal thread 21 is moved with merging relative to the silk braid cylinder 20；In addition, limiting is connected with compression piece 22 in the silk braid cylinder 20, the pressure
For contracting part 22 when the cylinder 30 that stretches is moved relative to the silk braid cylinder 20, which can compress or discharge the retracting cylinder
Gas in 30 inner chamber body 31 of body, so that the cooperation of the flexible cylinder 30 and compression piece 22 can replace traditional spring
Part, and screw thread is arranged in the silk braid cylinder 20, it is ensured that it, can be by silk braid cylinder 20 under enough cooperation intensity requirements
Diameter reduce as far as possible, and then space can be efficiently used, while save material cost.
Specifically, as shown in Fig. 2, in embodiments of the present invention, first internal thread 21 is along the inner cavity of the silk braid cylinder 20
It is evenly arranged on inner wall axial direction.It designs in this way when can ensure the flexible cylinder 30 along the axial direction of the silk braid cylinder 20
It is mobile, and then ensure that directionality is more accurate during the end push-and-pull object of flexible cylinder 30.
Specifically, as depicted in figs. 1 and 2, in embodiments of the present invention, also it is fixedly connected with limiting on the flexible cylinder 30
Lantern ring 32, first external screw thread 33 are formed on the limiting lantern ring 32, and during the silk braid cylinder 20 rotation, the limiting lantern ring 32 is logical
It crosses first external screw thread 33 to connect with first internal thread 21 so that the flexible cylinder 30 is along the axial direction of the silk braid cylinder 20
It is mobile.
In the present embodiment, the width of the limiting lantern ring 32 is much smaller than the length of the silk braid cylinder 20, and then 20 turns of silk braid cylinder
When dynamic, the flexible relative movement between cylinder 30 and the silk braid cylinder 20 more smoothly so that the work of electric pushrod
It is more efficient.In addition the limiting lantern ring 32 is preferably that welding or other modes being fixedly connected are fixed on the flexible cylinder 30
On lateral surface, which is formed on the lateral surface of the limiting lantern ring 32, and first external screw thread 33 with this
The thread size of one internal thread 21 is identical, and matching just.

In cavity 31.And then during the silk braid cylinder 20 rotation, the second end 222 limiting is mobile in the cylinder 30 that stretches；Herein substantially
The position of the second end 222 is motionless always, when silk braid cylinder 20 rotates, and the flexible cylinder 30 towards the silk braid cylinder 20 move when,
The second end 222 is equivalent to towards moving, and then compress the air in the cavity 31 in the cylinder 30 that stretches, and keeps entire electronic
Stability inside push rod；When silk braid cylinder 20 rotates, and the flexible cylinder 30 away from the silk braid cylinder 20 move when, the second end
222 are equivalent to towards movement outside the cylinder 30 that stretches, and then discharge the air compressed in the cavity 31, generate the power of rebound,
So that it is more convenient when electric pushrod is pushed outwardly, more easily.
Specifically, as shown in Fig. 2, in embodiments of the present invention, which should with the rotation edge of the silk braid cylinder 20
The axis direction movement of silk braid cylinder 20.Design can ensure whole knot when coordinating between cylinder 30 and silk braid cylinder 20 of stretching in this way
The intensity of structure is more preferable, and then total can realize lighter and smaller.
Specifically, as depicted in figs. 1 and 2, in embodiments of the present invention, which deviates from an end seal of the silk braid cylinder 20
It closes, the other end is equipped with the trepanning moved through for the second end 222 of supporting rod 22a, is gone back on the side wall of the second end 222
It is connected with the sealing element 23 that may be such that and sealing space is formed in the cavity 31.It can be designed so that matching in flexible cylinder 30 in this way
Close that design of part is less, while when the second end 222 of supporting rod 22a is moved relative to the inner cavity of the cylinder 30 that stretches, it can be with
Ensure state of the cavity 31 always in sealing, can ensure that the effect of gas compression and release is more preferable in this way；And structure
Also it is more simple.
Specifically, as shown in Figures 2 and 3, in embodiments of the present invention, the end of the second end 222 has further extended outward
Round platform 2211 is abutted, which is set on supporting rod 22a, and one end of the sealing element 23 is connected to abutting circle
On the side wall of platform 2211.Design can ensure that this is sealed in the stability connected in the second end 222 and the cavity 31 in this way
The reliability of interior sealing.
Specifically, as shown in figure 3, in embodiments of the present invention, the shape of the sealing element 23 and the cross section of the cavity 31
Shape is identical, and the peripheral surface of the sealing element 23 is connected on the inner wall of the cavity 31.Design is equally to ensure the chamber in this way
The stability and duration in 31 inner sealing space of body.
Specifically, as depicted in figs. 1 and 2, in embodiments of the present invention, which includes driving motor 11 and limit
