The object of the invention can be realized through following technical proposal: a kind of self-balancing roller shutter is provided; Comprise cord, be connected upper boom with said cord top edge, be connected and have weight so that the sagging lower beam of said cord with said cord lower limb with the coiling cord; Thereby also comprise having internal cavities, offer slotted eye on the said cover bar and be convenient to the lower limb of said cord and pass in and out said cover bar the cover bar of said lower beam in being contained in fully.
In above-mentioned self-balancing roller shutter, said self-balancing roller shutter also comprises motor and gear, and said motor is connected the said gear of drive and rotates with said gear, and said gear is connected to drive its rotation with said upper boom.
In above-mentioned self-balancing roller shutter, said cover bar is a straight-bar, and cross section becomes the oval ring of hollow.
In above-mentioned self-balancing roller shutter, the cavity height of said cover bar is greater than 2 times of said lower beam height.
In above-mentioned self-balancing roller shutter, the said big 5～20mm of shank diameter down of the aspect ratio of the internal cavities of said cover bar.
In above-mentioned self-balancing roller shutter, the said big 12mm of shank diameter down of the aspect ratio of the internal cavities of said cover bar.
Compared with prior art; When occurring rotating the error that causes when making the lower beam of roller shutter not reach ground because of motor gear; Though in fact lower beam is unsettled, it is positioned at the cover bar, and the cover bar can reach ground; Therefore from seeing that in appearance curtain is just to fall to the ground, can not cause the problem of light leak; And on the other hand; If the motor gear error cause descending excessive, when making cord volume long down (in certain scope, for example error reaches the 12mm scope), the cord lower end can enter into digestion voluntarily in the cover bar; The cover bar falls earthward and can not cause light leak, therefore can not influence appearance.
On the other hand; Between cover bar and lower beam, the cord is mobilizable; When ground was not parallel to the window top edge, the cover bar still can be put to the ground concordant with ground, and the lower beam of cord lower end is the inclination certain angle with respect to the cover bar; From also can't see in appearance, and the problem of light leak also is resolved.

The specific embodiment
Below be specific embodiment of the present invention and combine accompanying drawing, technical scheme of the present invention is done further to describe, but the present invention is not limited to these embodiment.
As shown in Figure 4, self-balancing roller shutter of the present invention comprises cord 2, upper boom 1, lower beam 3, cover bar 5.
Wherein, cord 2 can be any cord of prior art, for example puggaree, tulle etc.Cord 2 of the present invention relates generally to square, and top edge is connected to window upper topside edge, and lower limb then hangs down to ground 4 or window.Upper boom 1 is generally spool, through certain being rotatably connected to metope.Self-balancing roller shutter of the present invention also comprises motor and gear, and motor and gear connecting band moving gear rotate, and are connected to drive its rotation with upper boom 1 after the gear reduction.
In order not affect the appearance, the length of cover bar 5 is suitable with the length of lower beam 3, thereby consistent with whole roller shutter outward appearance formation, highly then the diameter than lower beam 3 is big, for example is 2 times of lower beam 3 diameters.Because the free travel of gear has 3～5mm, therefore should to supply lower beam 3 at least be 3～5mm in the cover bar 5 inner scopes of moving up and down to height, promptly covers the big at least 5mm of shank diameter under the aspect ratio of internal cavities of bar 5, for example than the big 5～20mm of shank diameter down.
