[0002] Casement windows are a type of window in residential houses. The window sash opens and closes along a certain horizontal direction, hence the name "casement window". Casement windows are divided into inward-opening and outward-opening types. Their advantages are small space occupation, large opening area, good ventilation, good sealing, and excellent sound insulation, heat preservation, and anti-seepage properties. Traditional casement windows are mostly opened and closed manually, but the windows are generally heavy, and the operation is time-consuming and labor-intensive. With technological advancements, motor devices are installed in casement windows to achieve automatic control of the casement windows.

[0003] Deficiencies of existing technology: The existing electric device for casement windows has a simple structure. When in use, the motor directly drives the connecting shaft on the side of the window to rotate, thereby driving the window to open and close. It has poor stability and is prone to collision in windy weather. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electric device for an outward-opening casement window to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an outward-opening casement window electric device, comprising a window mechanism and an electric mechanism, the window mechanism comprising a window frame, the side surface of the window frame being movably connected to the window body by a pin, the electric mechanism comprising a base, the bottom end of the base being fixedly connected to the bottom inner wall of the window frame, the side inner wall of the base being movably connected to a driving device, the top of the base being provided with a through slot, the top end of the base being movably sleeved with an auxiliary support rod by a pin, the top end of the auxiliary support rod being movably sleeved with a mounting plate by a pin, the top end of the mounting plate being fixedly connected to the bottom end of the window body by a bolt, the top end of the driving device being fixedly connected to a rotating rod, the top end of the rotating rod being movably sleeved with the bottom end of the mounting plate by a pin.

[0006] Furthermore, the driving device includes a slider, the side surface of the slider is movably connected to the inner wall of the side surface of the base, the inner wall of the side surface of the slider is fixedly connected to a driving motor, the top inner wall of the slider is fixedly connected to a mounting bracket, the side surface of the mounting bracket is movably connected to a driving bevel gear through a pin, the output shaft of the driving motor is fixedly connected to the side surface of the driving bevel gear, the top end of the slider is movably connected to a mounting shaft, the top end of the mounting shaft is fixedly connected to the bottom end of the rotating rod, the bottom end of the mounting shaft is fixedly connected to a driven bevel gear, and the side surface of the driven bevel gear is meshed with the side surface of the driving bevel gear.

[0007] Furthermore, the top end of the base is movably sleeved with a support rod via a pin, and the bottom end of the support rod is movably sleeved with the top end of the rotating rod via a pin.

[0008] Furthermore, a touch switch is movably connected to the inner wall of the side of the base.

[0009] Furthermore, a mounting hole is opened on the side of the base, a buffer spring is fixedly connected to the side of the mounting hole, and the side of the buffer spring is fixedly connected to the side of the touch switch.

[0010] Furthermore, a scale is provided on the top of the base corresponding to the position of the driving device, and a marking line is provided on the top of the driving device.

[0011] The technical effects and advantages of this utility model are:

[0012] 1. This utility model controls the movement of a drive mechanism installed in the interior of the room, which drives the rotating rod. This causes the rotating rod to push the mounting plate to rotate along the pin at the top of the auxiliary support rod. The auxiliary support rod rotates along the pin at the top of the base, thereby pushing the window body to rotate along the pin on the side of the window frame, thereby opening the window body. Simultaneously, the drive mechanism slides along the through slot. The rotating rod and the window body form a stable triangular structure to support the window body. When the window body is closed, the drive mechanism moves to the right side of the base, and the support rod, rotating rod, mounting plate, and auxiliary support rod all move directly above the base. This reduces space usage and helps improve the safety of the casement window.

[0013] 2. This utility model features touch switches on both ends of the base's side inner wall. When the slider slides along the base's side inner wall to either end, it contacts the touch switches, causing the touch switches to automatically stop the drive motor. Simultaneously, as the drive mechanism slides, the marked line points to the scale position at the top of the base, determining the window's main opening angle, facilitating operation for the operator.

The driving device 202 is controlled by the switch installed indoors to drive the rotating rod 205 to rotate, so that the rotating rod 205 pushes the mounting plate 204 to rotate along the top pin of the auxiliary support rod 206, and the auxiliary support rod 206 rotates along the top pin of the base 201, thereby pushing the window body 102 to rotate along the pin on the side of the window frame 101, so that the window body 102 is opened. At the same time, the driving device 202 slides along the through groove 203. At this time, the rotating rod 205 and the window body 102 form a triangular stable structure to support the window body 102. When the window body 102 is closed, the driving device 202 moves to the right side of the base 201. At the same time, the support rod 207, the rotating rod 205, the mounting plate 204 and the auxiliary support rod 206 are all moved to the top of the base 201 to reduce the occupied space.
