Description

Technical Field

[0001] The invention relates to an electric window opening mechanism, and more particularly to an electric window opening mechanism with a window sash capable of being opened to a large extent. Background Art

[0002] Electric window opening mechanism is widely used on windows. At present, domestic natural smoke exhaust ventilation skylights, such as Figure 1 The electric window opening mechanism of the prior art shown can be opened to a maximum of 90°, and is driven by only one electric push rod. In the figure, the window sash 4 is connected to the driving end of the electric push rod 1; the electric push rod 1 is set on the window frame through a hinge shaft assembly 5. The figure shows the layout of the window sash in the closed state and the layout of the window sash in the open state.

[0003] In this way, the maximum opening angle of the window sash is about 90°. When the wind blows from the window sash hinge side to the opening direction, the smoke exhaust ventilation area of ​​the entire opening cannot be 100% utilized due to the obstruction of the window sash, which affects the efficiency of ventilation and smoke exhaust. Summary of the invention

[0004] In view of the above problems, the present invention provides an electric window opening mechanism with which a window sash can be opened to a large extent, which is particularly suitable for window structures such as natural smoke exhaust ventilation skylights.

[0005] In order to achieve the above-mentioned purpose, the present invention provides an electric window opening mechanism, including an electric push rod with a pushing end connected to the window sash, the cylinder of the electric push rod is fixed on a bracket serving as a support arm, and the bracket is rotatably fixed to the window frame via a hinge shaft.

[0006] That is to say, the fixed cylinder of the electric push rod is driven to rotate in an eccentric manner through the support arm; and the push rod that pushes and pulls reciprocatingly in the fixed cylinder of the electric push rod realizes the closing and opening of the window sash through action. Therefore, when designing accordingly, the structural design is used to ensure that the actions between the components will not interfere with each other and that the required functions can be achieved.

[0007] In a preferred embodiment, the bracket in the electric window opening mechanism includes two support rods arranged at an acute angle, one end of the two support rods is hinged to the hinge shaft, and the other ends are respectively fixed to the cylinder of the electric push rod.

[0008] As needed, the bracket can also be a support arm, and the two ends of the support arm are respectively connected to the hinge shaft and the cylinder of the electric push rod to meet the necessary working strength, or the connection between the support arm and the electric push rod cylinder is achieved by setting multiple fixing components to ensure the relative fixation of the electric push rod and the bracket.

[0009] The present invention utilizes the principle of the centrifugal circle to realize that the window sash can be opened 0-180 degrees. This structure is easy to manufacture and simple to implement, and can greatly improve the ventilation efficiency of the window. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 The utility model is a schematic diagram of the principle of the electric window opening mechanism of the sunroof in the prior art.

[0011] Figure 2 It is a schematic diagram of the sunroof electric window opening mechanism of the present invention in the closed state.

[0012] Figure 3 It is a schematic diagram of the open state of the electric window opening mechanism of the sunroof of the present invention. DETAILED DESCRIPTION

[0013] like Figure 2 and 3 As shown, in the electric window opening mechanism of the present invention, the electric push rod 1 is equipped with an L-shaped acute angle bracket 3, and the position of the bracket angle is the fixed point hinge shaft 2, which is fixed on the bottom frame of the skylight. When the motor is started, the window sash rotates around the hinge, and the motor rotates around the rotation axis of the transmission mechanism. The rotation tracks of the two components are two non-concentric circles. When the window sash is opened more than 90°, the motor rotates to the part above the skylight, and the window sash can be opened 180° without interfering with the bottom frame of the skylight.

[0014] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
