[0007] This utility model relates to a gear transmission mechanism for intelligent doors and windows, including a gear seat and a transmission gear mounted on top of it, as well as a lubrication gear meshing with the transmission gear. A fixing ring is fixed above the lubrication gear, and a connecting groove and an annular groove are formed inside the lubrication gear. The connecting groove is connected to a receiving cavity formed inside the fixing ring by a square through groove. The bottom end of the connecting groove is connected to an oil supply channel. An oil supply port is formed on the outer wall between the teeth of the lubrication gear. A transverse channel and a stop block are connected between the oil supply port and the oil supply channel, and the connecting groove and the stop block are both trumpet-shaped with different diameters at both ends. The opening and closing of the connecting groove is controlled by the transverse movement of the stop block.

[0008] Furthermore, a sliding plate is slidably provided in the smooth cavity opened in the lubricating gear, and a smoothing rod one and a smoothing rod two are respectively fixed on the upper and lower sides of the side wall of the sliding plate, and the smoothing rod one is fixedly connected to one side of the stop block.

[0024] 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.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figure 1 - Figure 4 As shown, this utility model is a gear transmission mechanism for intelligent doors and windows, including a gear seat 1 and a transmission gear 2 disposed above it, and a lubrication gear 3 meshing with the transmission gear 2. A fixing ring 4 is fixed above the lubrication gear 3. A connecting groove 302 and an annular groove 303 are opened inside the lubrication gear 3. The connecting groove 302 is connected to the receiving cavity 401 opened in the fixing ring 4 through a square through groove 301. The bottom end of the connecting groove 302 is connected to the oil supply channel 305. An oil supply port 307 is opened on the outer wall between the teeth of the lubrication gear 3. A transverse channel 306 is connected between the oil supply port 307 and the oil supply channel 305. A stop block 5 cooperates with the connecting groove 302. The connecting groove 302 and the stop block 5 are both trumpet-shaped with different diameters at both ends. The opening and closing of the connecting groove 302 is controlled by the transverse movement of the stop block 5.

[0027] This embodiment provides a gear transmission mechanism for intelligent doors and windows. The number of teeth on the lubricating gear 3 is less than the number of teeth on the transmission gear 2. The receiving cavity 401 is filled with lubricating oil. The lubricating oil enters the connecting groove 302 through the square through groove 301, causing the stop block 5 to move laterally into the annular groove 303. A gap is created between the connecting groove 302 and the stop block 5. The lubricating oil enters the annular groove 303 through the connecting groove 302. Then, the lubricating oil is discharged from the oil outlet 307 through the oil delivery channel 305 and the transverse channel 306 to the meshing transmission gear 2 and lubricating gear 3. The stop block 5 can also move laterally to close the connecting groove 302, controlling the opening and closing of the connecting groove 302, thereby controlling the flow of lubricating oil.

[0028] The lubrication gear 3 has a sliding plate 6 slidably disposed in the smooth cavity 304. The upper and lower sides of the side wall of the sliding plate 6 are respectively fixed with a smooth rod 501 and a smooth rod 701. The smooth rod 501 is fixedly connected to one side of the stop block 5. The smooth rod 501 and the smooth rod 701 are slidably connected to the lubrication gear 3. The sliding plate 6 and the smooth rod 501 can be moved laterally by the push block 7.

[0029] The smooth groove 308 on the outer wall of the lubrication gear 3 is slidably connected to the push block 7, and the push block 7 is coaxially fixed with the smooth rod 701. The push block 7 is located between the teeth of the lubrication gear 3 and below the oil inlet 307. One end of the push block 7 is outside the lubrication gear 3. When the lubrication gear 3 rotates, the push block 7 periodically contacts the teeth of the transmission gear 2 as the lubrication gear 3 rotates. The teeth of the transmission gear 2 will push the push block 7 to move laterally.

[0030] The smooth cavity 304 is equipped with a spring, and the two ends of the spring are fixedly connected to the lubrication gear 3 and the sliding plate 6 respectively. After the transmission gear 2 separates from the push block 7, the spring drives the sliding plate 6 to reset.

[0031] Among them, the top surface of the gear seat 1 is rotatably mounted with rotating shaft 101 and rotating shaft 102, which are respectively fixed to the transmission gear 2 and the lubrication gear 3.

[0032] The fixed ring 4 has a threaded groove 402 at its top end that communicates with the receiving cavity 401. The threaded groove 402 is threadedly connected to the sealing bolt 8. The sealing bolt 8 is unscrewed, and lubricating oil is added into the receiving cavity 401 through the threaded groove 402. Then the sealing bolt 8 is screwed in to block the threaded groove 402.

[0033] It is understood that this utility model can periodically apply lubricating oil to the meshing point of the transmission gear 2 and the lubrication gear 3, and then control the flow of lubricating oil through the stop block 5.

[0034] A specific application of the operation process in this embodiment is as follows: When the smart door and window are working, the transmission gear 2 rotates under external drive, thereby driving the lubrication gear 3 to rotate. When the teeth of the transmission gear 2 contact the push block 7 and continue to transmit, it will drive the push block 7 to move laterally towards the central axis of the lubrication gear 3. Further, through the smooth rod 2 701 and the sliding plate 6, the smooth rod 1 501 moves laterally, thereby causing the stop block 5 to move into the annular groove 303, creating a gap between the stop block 5 and the connecting groove 302. At this time, the lubricating oil flows out through the square through groove 301, the connecting groove 302, the annular groove 303, the oil supply channel 305, the transverse channel 306 and the oil outlet 307 and is coated on the meshing point of the transmission gear 2 and the lubrication gear 3. The transmission gear 2 and the lubrication gear 3 continue to move, and the teeth of the transmission gear 2 separate from the push block 7. The spring drives the sliding plate 6 to reset, thereby causing the outer wall of the stop block 5 to press against the side wall of the connecting groove 302 to block the connecting groove 302 and prevent the lubricating oil from continuing to flow.
