Description

Technical Field

[0001] The utility model relates to the technical field of lifting windows, in particular to an anti-pinch structure for an electric lifting window. Background Technique

[0002] Most of the existing lifting windows are composed of a fixed window sash and a movable window sash. The fixed window sash can be installed at the top or bottom of the window frame, and the movable window sash is vertically slidably installed on the window frame. Generally, the opening and closing of the window sash are realized by driving the movable window with a motor.

[0003] Among them, the assembly structure of the fixed window sash or the movable window sash mainly adopts that the window sash profile is provided with an installation slot for the window sash glass to be embedded and matched, resulting in the surface of the window sash profile protruding from the surface of the window sash glass, forming a stepped position. When the user places the hand on the top of the fixed window sash, if the movable window sash is accidentally controlled to move down and the user does not withdraw the hand in time, it is very easy to cause the stepped position at the window sash profile and the window sash glass of the movable window sash to pinch the user's hand at the top of the fixed window sash. At this time, due to the large weight of the movable window sash, the clamping force is large, which is easy to cause greater physical harm to the user and there are relatively large potential safety hazards.

[0004] Therefore, further improvement is needed. Content of the Utility Model
