The specific embodiment

Fig. 1-shown in Figure 3 is a kind of embodiment of the present utility model.Two cover the utility model are set in window frame 2 and window 1,4.

Window

1,4 is installed in the window frame 2, and roller 5 is equipped with in the bottom of

window

1,4, and is positioned on the guide rail 6 of window frame 2, can move the resistance when minimizing

window

1,4 moves along guide rail 6.The utility model is made up of the electronic drive disk assembly 3 that is loaded on window frame 2 and window 1, power transmission component 20.Electronic drive disk assembly 3 is to be made of motor 7, key 8, screw rod 9, nut 13, bearing support 21, supporting base 22, and bearing support 21 is fixed on the window frame 2, and is connected with motor 7, and screw rod 9 is connected with motor 7 by key 8, and places on the bearing support 21.Motor 7 is minitype speed reducing motors, and nut 13 is on screw rod 9, and coupling, and nut 13 is to be made by the material that self lubricity is arranged.Described screw rod 9 is 2 lines or 3 lines or 4 line screw threads.Screw rod 9 other ends are positioned on the supporting base 22, and supporting base 22 is fixedlyed connected with window frame 2.Power transmission component 20 is to be made of transmission piece 15, directive wheel 10, axle 11, back-up ring 12, power transmission pillar 16, roller 17, fixed block 18.Transmitting on the piece 15 has pit, puts nut 13 on the pit, and gapped 14; Two ends that transmit piece 15 respectively have a power transmission pillar 16, power transmission pillar 16 other ends roller 17 of packing into, fixed block 18 is fixedlyed connected with window 1, between two rollers 17, transmit on the piece 15 two axles 11 also fixedly are housed, axle 11 is connected with directive wheel 10, and with back-up ring 12 directive wheel 10 can not be moved vertically, two directive wheels 10 be positioned at the

spigot surface

19,19 of window frame 2 '.Described directive wheel 10 is ball bearings.

The screw rod 9 of present embodiment and nut 13 also can be used ball screw and ball nut, become rolling screw, make stable drive and noiselessness.

During use, a utility model is loaded on window frame 2 and the window 1, another the utility model is loaded on window frame 2 and the window 4.If

window

1,4 is closed condition, now to open window 1, as long as motor 7 energising rotations, make screw rod 9 rotations through key 8, at this moment nut 13 is positioned at the pit that transmits piece 15, nut 13 can only move along the axis of screw rod 9, meanwhile two directive wheels 10 are in spigot surface 19,19 ' rolling, at this moment just the rotation motion motion that is in line, thrust is passed to transmission piece 15, transmit piece 15 and pass to window 1 by power transmission pillar 16, roller 17 and fixed block 18, the roller 5 of window 1 is rolled on guide rail 6, window 1 is progressively opened.If the guide rail 6 of window frame 2 has injustice slightly, make power transmission component 20 along with certain floating arranged up and down, this floats and can enable to open smoothly window 1 by gap 14 compensation adjustments between screw thread 13 and transmission piece 15 biends.When window 1 is opened to the needs size, as long as stop the rotation of motor 7.When closing window 1, as long as motor 7 reverse rotations just can realize.The utlity model has simple in structure, stable drive, the advantage that noise is little.
