Description

The pull-up electrically driven curtain

Technical field

The present invention relates to a kind of electrically driven curtain, especially refer to a kind of automobile-used, have a pull-up electrically driven curtain of automatic open close up and down.

Background technology

Automobile-used curtain can be used to sunshade and block vision, to increase occupant's comfort level, its importance is also paid attention to gradually widely, and the operation of existing curtain can be divided into two kinds of manual type and electrodynamic types, the manual type curtain such as the patent No. are that the Chinese utility model " automobile-used rolling curtain " (notification number is CN2265921Y) of ZL96217611.7 is exactly wherein a kind of, it comprises window curtain fabric, spring, axle and reel, the two ends of spring link to each other with reel with axle respectively, and place in the reel together, one end of window curtain fabric is captiveed joint with reel by the slotted eye on the outer cover, the lower end of window curtain fabric is provided with a set collar, during use arbitrarily drop-down or on send and reach purpose, because it is small and exquisite, simply attractive in appearance, but regulated at will light again, and more welcome.But its shortcoming is: use extremely inconvenient from its occupant far away; Moreover, because the shape of vehicle rear window is trapezoidal, then need to combine with above-mentioned three curtain, this not only installation and maintenance inconvenience, and need multi-pass operation ability draw-back curtain, it is pretty troublesome therefore to operate.For this reason, people design the electrodynamic type curtain, it comprises motor, crank, be positioned at crank both sides and pull bar rigidly connected with it, swing arm and back timber and be wound on window curtain fabric on the spring shaft, described pull bar is rigidly connected by an end of pass joint and swing arm, the other end of swing arm then supporting top beam also can slide with respect to back timber, the top end part of back timber and window curtain fabric fixes, during use, motor rotates, and drives crank and rotates, and pull bar rotates thereupon, and the drive swing arm is rotated, drive the back timber be positioned at the swing arm upper end thus and move up and down, thereby make and draw on the window curtain fabric that fixes with back timber or send down, therefore use very convenient.But because abnormity components such as employing crank, make and make difficulty, cost is higher, and whole device is heavy, be difficult to install, and this device generally is installed under the car trunk cover plate, and will on the cover board open a notch, so that pull out window curtain fabric, therefore, if will need reequip boot-lid panel when the automobile of place in operation is reinstalled, be used widely thereby influenced it.

Summary of the invention

Technical matters to be solved by this invention is that a kind of simple in structure, easy to manufacture, pull-up electrically driven curtain that cost is low is provided at the present situation of above-mentioned prior art.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: the crossbeam that this pull-up electrically driven curtain comprises driver train, is wound on the window curtain fabric on the spring shaft and is fixed on the window curtain fabric top is characterized in that also comprising:

Two first guide rail and second guide rails that are positioned at the vertical setting of window curtain fabric both sides are the section bar of hollow, and have relative longitudinal slot in a relative side;

Two sections drag-lines that drive by driver train, corresponding with described two guide rails respectively, each drag-line penetrates from its cooresponding guide rail first end, vertically run through guide rail after, after second end of guide rail is walked around the pulley that is arranged on this place, turn round, vertically run through guide rail again and pass from first end;

Two slide blocks, in described two guide rails, respectively be provided with one, each slide block is separately fixed on the interior corresponding drag-line of corresponding guide rail, and described each slide block also has the connecting portion that exposes from the longitudinal slot of described respective track, be used for being connected with the two ends of crossbeam respectively.

Described driver train can be formed by motor with the reel that motor output shaft links, and has the spiral winding slot on the perisporium of described reel; Described two sections drag-lines are of winding one, and, being positioned at the first guide rail internal fixation has the drag-line of slide block and is positioned at second guide rail and walks around the corresponding spiral winding slot that the drag-line of pulley is around in reel respectively, and is positioned at drag-line that first guide rail walks around pulley and is positioned at the second guide rail internal fixation and has the drag-line of slide block directly to link to each other.

Described driver train can be made up of the reel that motor and motor output shaft link, and has the spiral winding slot on the perisporium of described reel, and described two sections drag-lines are independently two of difference, walk around corresponding spiral winding slot and revolution respectively.

Driving gear and two driven gears that are meshed with driving gear respectively that described driver train also can comprise motor, link with motor output shaft, be respectively arranged with coaxial reel on described two driven gears, described two sections drag-lines are for independently two of difference, respectively on this two reel.

Can be with flexible pipe loosely outside the drag-line between described reel and guide rail, and the place is provided with the flexible pipe fixed block at contiguous reel, it is allowing that drag-line passes and with the aperture of hose end first speed outside it along having on the direction of drag-line.

The described flexible pipe fixed block outside can be provided with the flexible pipe shock absorber, this shock absorber comprise be positioned at hollow cylinder extended on the flexible pipe fixed block lateral wall and stretch into this hollow cylinder, the cross section is the hose coupling of U type, described flexible pipe termination is positioned at this hose coupling and drag-line passes the bottom of hose coupling enters aperture on the flexible pipe fixed block, the oral area outer side edges of described hose coupling is provided with outward extending flange, is provided with between this flange and the fixed block lateral wall to make hose coupling have spring to flexible pipe side shifting trend.

Two ends can be installed in the described crossbeam be exposed to the outer expansion link of crossbeam, and described each slide block fixes with the two ends of expansion link respectively.

Can axially be provided with the inwall that is divided into two independent inner chambers respectively in described first, second guide rail, up drag-line and descending drag-line in the described guide rail lay respectively in above-mentioned two inner chambers.

Described first, second guide rail first end place also can be equipped with the fixed pulley that drag-line is turned to.

Compared with prior art, the invention has the advantages that: owing to adopt simple and practical pulley and drag-line, make it be easy to make, cost is low, and can need not the boot-lid panel of vehicle is done bigger change, therefore with comparatively flexible way installation again, cost of installation is low, also can reinstall the automobile of place in operation.Adopt the mode of a reel, the drag-line of wraparound is put in the empty spiral winding slot around being drawn out drag-line, make the space of reel and material obtain saving like this,, and improved reliability of operation with the saving cost; Adopt shock absorber, can prolong the service life of drag-line, improve the drawing stationarity of window curtain fabric; And the expansion link in the employing crossbeam, applicable to difform automotive window; Therefore, the present invention more can satisfy people's operating needs, also makes it have more the market competitiveness.
