The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Referring to Fig. 2, a kind of electronic ceiling curtain comprises the track 1 that is positioned at both sides, and the two ends of track 1 are connected with end cap, and an end of every track 1 is provided with folding curtain motor 2, and the other end connects through the track 1 of synchronous connecting axle 3 with both sides.Owing to used folding curtain motor 2, stroke limit is that electronic type is spacing, the stroke positioning can not occur and cause light leak; And folding curtain motor 2 can be hampered and stop; Protected motor effectively, track 1 also can be different from existing straight track thus, and becomes the curved track with radian.

Referring to Fig. 3, be provided with belt 12 in the track 1, the two ends of belt 12 connect end cap respectively.The inboard of belt 12 is a profile of tooth, and coaster 41 is fixed on the belt 12 through fixture 411, has bigger contact surface between fixture 411 and the belt 12, and is stressed more even, makes transmission respond well.Be provided with gear 111 in the end cap of track 1, the profile of tooth of the tooth of gear 111 and belt 12 is complementary, and both intermesh, and the rotation through gear 111 drives belt 12 thus and slides, owing to be engaged transmission, can not cause the distortion of belt 12 thus easily.

The lining 4 of ceiling curtain; Be generally sunshade and use textile; The end of its both sides is fixed on the coaster 41, and the remainder of both sides evenly is provided with pulley 42, when 2 runnings of folding curtain motor drive belt 12 slips; The end of lining 4 is sliding in track 1 under the drive of belt 12, and remainder is sliding through pulley 42 and can in track 1, slide according to end then.

Because folding curtain motor 2 might be because manufacturing process small asynchrony phenomenon may occur thus.Track 1 connection of synchronous connecting axle 3 with both sides is set, realizes forced synchronism through mechanical system, thereby eliminate small difference.Referring to Fig. 4-Fig. 6, connecting axle 3 comprises connection main shaft 21 synchronously, connects directly heel end lid connection of main shaft 21, also can be that the two ends that connect main shaft 21 are connected with Coupling Shaft 22 respectively, and Coupling Shaft 22 connects end cap more respectively.In order to make that need not to regulate the length that connects main shaft 21 also can normally use, connect the mode that main shaft 21 and Coupling Shaft 22 adopt sockets, be socketed on the Coupling Shaft 22 as connecting main shaft 21.Rotating shaft 221 diameters that connect on the outside of Coupling Shaft 22 increase, and are arranged with jump ring 222 on its end, and are preferred, are the C type, so that rotating shaft 221 is fixing.End cap comprises interconnected drive end bearing bracket 11 and rear end cap 23, and rotating shaft 221 is passed the centre bore 235 of rear end cap 12 and located, and cooperates with drive end bearing bracket 11 interior gears 111.Be symmetrically arranged with the first arc bulge loop 223 on the outside, bottom surface of rotating shaft 221; Accordingly, being symmetrically arranged with the second arc bulge loop, 112, the first arc bulge loops 223 and the second arc bulge loop 112 on the inside bottom surface of gear 111 works in coordination; Form a full circle, and belt 12 is arranged on the gear 111.Thus, when belt 12 driven gears 111 rotated, gear 111 can drive turning cylinder 22 and rotate, thereby through connecting the turning cylinder 22 that main shaft 21 is delivered to opposite side, forced to realize being synchronized with the movement of two side gears 111 and belt 12.

Installing for ease, rear end cap 23 adopts hasp type to be connected with drive end bearing bracket 11.Rear end cap 23 is provided with hasp 231 near a side of lining 4; Be installed in the rear end cap 23 through torsion spring 232 and location Coupling Shaft 233; Be symmetrically arranged with the first arc ring 234 that extends radially outwardly from centre bore 235 on the outer circumference of the centre bore 235 of rear end cap 23, the corresponding position, installing hole 113 position of the inboard of drive end bearing bracket 11 is symmetrically arranged with the second arc ring 114 that extends internally from outer periphery.During installation, the second arc ring 114 is positioned at first arc ring 234 outside radially, its medial surface and the first arc ring 234 lateral surface butt radially radially, thus prevent that rear end cap 23 from moving up and down.Hasp 231 places under the active force of torsion spring 232 in the breach 115 of drive end bearing bracket 11 1 sides, does side-to-side movement to prevent rear end cap 23.When needs are dismantled synchronous connecting axle 3, only need to rotate a hasp 231 and leave breach 115 and get final product.

The above is merely the preferred implementation of the utility model; Should be pointed out that for those of ordinary skill in the art, do not breaking away under the principle prerequisite of the utility model; Can also make various deformation and improvement, this also should be regarded as the protection domain of the utility model.
