[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-4 As shown, it includes a fixed frame 1, a front cover plate 2 installed on the front side of the fixed frame 1, a motor 13 installed inside the fixed frame 1, an external gearbox 14 at the front end of the motor 13, a reducer 15 at the front end of the external gearbox 14, and the reducer 15 drives the window to rise and fall through a sprocket structure 16. A rotary connection slot 17 for manual drive is provided on the side of the external gearbox 14. A hidden door 3 and a hidden door 4 are provided in the front cover plate 2. Both the upper and lower ends of the hidden door 3 and the hidden door 4 are provided with stepped slots. The hidden door 3 and the hidden door 4 are installed through a hidden structure. The rotary connection slot 17 is located directly behind the lower half of the hidden door 4. A folding handle assembly is provided in the fixed frame 1 inside the hidden door 3.

[0024] See Figures 1-6 As shown, the rotating shaft of the motor 13 and the reducer 15 are connected by a drive shaft 20. The drive shaft 20 passes through the external gearbox 14. The rotary connection slot 17 is rotatably mounted on the side wall of the external gearbox 14. The rotary connection slot 17 has a hole on its outer side. The rear end of the rotary connection slot 17 is connected to the drive shaft 20 by a transmission gear set 18 and a bevel gear set 19.

[0025] During normal operation, the motor 13 can drive the reducer 15 through the drive shaft 20, which in turn drives the window to rise and fall, thus achieving normal operation. The rotating connection slot 17 is provided so that even when the motor 13 stops working, it can still rotate to drive the drive shaft 20 to rotate through the transmission gear set 18 and the bevel gear set 19, thereby enabling manual adjustment of the window's rise and fall.

[0026] See Figures 1-5As shown, the hidden structure includes two fixing members 7 installed in the fixed frame 1. The fixing member 7 has a movable groove 8. The upper and lower sides of the movable groove 8 are respectively provided with guide strips 12. The middle of the movable groove 8 is provided with a sliding rod 10. The slider 9 is slidably installed in the movable groove 8 through the sliding rod 10 and the guide strips 12. A spring 11 is sleeved on the outside of the sliding rod 10. The spring 11 is located behind the slider 9. The middle of the two rear sides of the hidden door 3 is respectively connected to a rotating member 6. The rotating member 6 is rotatably connected to the slider 9 through a rotating shaft. The fixed frame 1 is provided with partitions 5 at both ends of the inner side of the hidden door 3. The handle assembly is located between the two partitions 5. The two fixing members 7 on the rear side of the hidden door 3 are both installed on the partitions 5.

[0027] As an optimized solution of this utility model, the sliding rod 10 and guide bar 12 allow the slider 9 to slide within the movable groove 8. Simultaneously, the spring 11 pushes the slider 9 outward, positioning the hidden door 3 against the opening of the front cover plate 2, thus maintaining the stability of the hidden door 3. When needed, the hidden door 3 is pushed inward, compressing the springs 11 at both ends and causing the hidden door 3 to move inward as a whole. At this point, the upper and lower ends of the hidden door 3 separate from the opening of the front cover plate 2, allowing it to rotate around the pivot. After rotating the hidden door 3 upward, the lower half of the space inside the hidden door 3 is exposed, allowing the handle assembly to be removed or placed. After use, the hidden door 3 is rotated downward and pushed inward. Once the angle is corrected, releasing the handle allows the spring 11 to push the hidden door 3 to close again. Similarly, the hidden door 4 can be operated to expose the rotating connection slot 17 for use or to close the hidden door 4.

[0028] See Figures 1-7 As shown, the grip assembly includes a rotating handle 21 and a connecting rod 22 that are rotatably connected. When the two are unfolded, the maximum included angle is 90°. The length of the connecting rod 22 is less than the length of the rotating handle 21. The front end of the connecting rod 22 is provided with a plug 23 that matches the shape of the hole in the rotating connection slot 17. A rotating sleeve 24 is fitted on the connecting rod 22.

[0029] As an optimized solution of this utility model, the plug 23 is used in conjunction with the rotating connection slot 17. After the grip device is unfolded, the plug 23 is inserted into the rotating connection slot 17, and the rotating handle 21 can be rotated to make the rotating connection slot 17 rotate. At the same time, the rotating sleeve 24 can be easily gripped to hold the connecting rod 22 and prevent it from tilting.

[0030] The usage process of this utility model:

[0031] After the window is installed, it can be used daily by controlling the motor 13. In case of an emergency such as a power outage, the motor 13 will not work properly. You can press the hidden door 3 inward and rotate it to open. Open the hidden door 4 in the same way. Then take out the handle assembly, insert the plug 23 into the rotating connection slot 17, and push the handle assembly to drive the reducer 15 to rotate. After use, you can close the hidden door 3 and the hidden door 4 without affecting the daily appearance.

[0032] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
