The power assisting structure for opening and closing the window sash according to the embodiment of the utility model is described in detail below.
As shown in fig. 1 and fig. 2, an assistance structure for opening and closing a window sash is provided in an embodiment of the present utility model. The power assisting structure comprises a base 1, a connecting part 2, a mounting seat 3, a sliding block 4 and an elastic piece 5. Wherein the base 1 is fixed to a sash 200 (only a part of the sash is shown in fig. 1) and has two hinge points. One ends of the connection part 2 and the mount 3 are hinged to two hinge points of the base 1, respectively, and the other end of the connection part 2 is hinged to a window frame connector 10 (only a part of a window frame is shown in fig. 1) as a rotating member. The sliding block 4 and the elastic piece 5 are arranged on the mounting seat 3, and the sliding block 4 is in sliding fit with the mounting seat 3 so as to squeeze the elastic piece 5. And, slider 4 still articulates with connecting portion 2 to make the casement in rotatory open and shut's in-process, elastic component 5 can apply the effort of different directions to slider 4, and transmit the effort to connecting portion 2, thereby all plays the helping hand effect to casement opening and shutting.
Specifically, in the present embodiment, the base 1 is fixed to the window sash 200 to move with the opening and closing of the window sash 200. The base 1 has a first joint 101 and a second joint 102, the first joint 101 is used for hinging with the connecting portion 2, and the second joint 102 is used for hinging with the mounting seat 3.
The connection part 2 is of an elongated plate-like structure (but not limited to this structure), and a first end (i.e., a left end in fig. 1) of the connection part 1 is adapted to be hinged with the window frame connector 10, and a second end (i.e., a right end in fig. 1) of the connection part 1 is adapted to be hinged with the first hinge point 101. Further, as shown in fig. 2, the surface of the connection part 2 is provided with a rotation hole 21 for hinging with the slider 4.
As shown in fig. 2, the mounting base 3 is provided with a movable slot 301 along a preset direction, and the preset direction is a connecting line direction (i.e., a length direction) between the first end and the second end of the mounting base 3. Wherein, the first end (i.e. the right end in fig. 2) of the mounting seat 3 is hinged to the second hinge point 102 of the base 1, and the second end (i.e. the left end in fig. 2) of the mounting seat 3 is a free end, so that the second end of the mounting seat 3 can freely rotate around the first end at one side (i.e. below) of the connecting portion 2.
As shown in fig. 2, the slider 4 is movably disposed in the movable groove 301 along a predetermined direction, and a rotating post 41 is disposed on a side of the slider 4 facing the connection portion 2, and the rotating post 41 is rotatably disposed in the rotating hole 21, so that the slider 4 can rotate around a central axis of the rotating post 41 relative to the connection portion 2 and cannot move relative to the connection portion 2.
As shown in fig. 3, the elastic member 5 is disposed in the movable slot 301, and a first end (i.e., a left end in fig. 2) of the elastic member 5 abuts against the slider 4, and a second end (i.e., a right end in fig. 2) of the elastic member 5 abuts against an inner wall of the movable slot 301. Accordingly, the elastic force can be applied to the slider 4 by the elastic member 5, and accordingly, since the slider 4 and the connecting portion 2 are relatively rotatable but not relatively movable, the elastic force provided by the elastic member 5 is transmitted to the connecting portion 2 through the slider 4 to apply forces in different directions to the connecting portion 2 in different states.
As shown in fig. 4 to 6, in the present embodiment, the slider 4 is switched between three states during the rotation of the window sash 20 to open and close. In the first state, the rotation center of the rotation column 41 is located on the left side of the line connecting the first hinge point 101 and the second hinge point 102 (as shown in fig. 4); in the second state, the rotation center of the rotation column 41 is located on the line connecting the first hinge point 101 and the second hinge point 102 (as shown in fig. 5); in the third state, the rotation center of the rotation column 41 is located on the right side of the line connecting the first hinge point 101 and the second hinge point 102 (as shown in fig. 6).

In the critical state, since the rotation center of the rotation column 41 is located on the line connecting the first hinge point 101 and the second hinge point 102, the elastic force of the elastic member 5 does not affect the window sash 20; however, once the window sash 200 is out of the critical state, whether from the critical state to the open state or from the critical state to the closed state, the elastic member 5 provides elastic pushing force, thereby assisting the opening and closing of the window sash 200. In addition, in the closed state, the elastic member 5 always provides elastic thrust, so that the sealing performance of the window sash 200 can be ensured. Furthermore, it should be understood that in the present embodiment, the assistance is mainly reflected in the process of switching the window sash 200 from the critical state to the closed state or the open state, and the thrust of the elastic member 5 needs to be overcome in the process of switching the window sash from the closed state or the open state to the critical state.
