[0002] An electric window opener is a device used to open and close windows. An electric window opener generally comes with a speed reducer. A number of gear sets are arranged inside the speed reducer. Each set of gear sets is arranged on the housing through a corresponding mounting shaft. When the gear sets rotate, the mounting shafts also rotate synchronously. Therefore, bearings need to be installed at both ends of the mounting shafts, and the gear sets need to be fixed to the corresponding mounting shafts. It can be seen that the assembly process is relatively complex and will increase the production cost.

[0003] For example, a multi-rotation angle window opener disclosed in Chinese Patent Application No.: CN202320844500.8 specifically discloses that "the first gear is fixed on the rotating shaft, and the stepping motor drives the glass window to rotate along both sides of the glass window around the axis of the rotating shaft through the second gear and the first gear; the control switch drives the stepping motor to rotate forward and backward through the control panel". The first gear is fixed on the rotating shaft, and the assembly process is relatively complex, which will increase the production cost.

[0033] Please refer to Figures 1 to 9 as shown, which shows the specific structure of the preferred embodiment of the present utility model, and is an electric chain window opener.

[0034] Among them, each group of the gear sets 20 is installed through the mounting shaft 21. Both ends of the mounting shaft 21 are fixed to the housing 10, and the gear sets 20 are rotatable on the corresponding mounting shafts 21. This design saves the need for bearings 16, and the mounting shafts 21 do not need to be riveted to the gear sets 20 either. Therefore, the structure is simpler, and the assembly is more convenient and fast, which can greatly reduce the production cost.

[0035] Please refer to Figures 1 - 3As shown in the figure, the present application provides an electric chain window opener, which includes a housing 10, a motor 11, at least one set of gear sets 20, and a chain 22; the output shaft of the motor 11 is connected to the power input end of the gear set 20 and transmits power to the gear set 20; each set of the gear sets 20 is provided with a mounting shaft 21, and lubricating oil is coated on the mounting shaft 21; both ends of the mounting shaft 21 are fixed to the housing 10, and the gear set 20 can rotate on the corresponding mounting shaft 21; the chain 22 is engaged with the sprocket at the power output end of the gear set 20, and the gear set 20 transmits power to the chain 22. The gear set 20 is arranged inside the housing 10, and the chain 22 is driven by the gear set 20 to extend or retract from one side of the housing 10. The power of the motor 11 is transmitted to the chain 22 by the gear set 20, and the chain 22 can extend or retract. Both ends of the mounting shaft 21 are fixed to the housing 10, and the mounting shaft 21 is coated with lubricating oil. The gears of the gear set 20 can rotate around the mounting shaft 21, that is, the gears can rotate on the mounting shaft 21. It can be seen that the mounting shaft 21 does not require a bearing 16 for installation, and the gears do not need to be riveted / pinned to the mounting shaft 21. The whole structure becomes simpler, saving time, effort and cost during assembly. The worm gear 211 and the worm 12 have a self-locking function, so the gear set 20 can be well prevented from reversing. The housing 10 is preferably a metal housing 10, and the two ends of the mounting shaft 21 are radially reduced, which is convenient for the mounting shaft 21 to be installed in the housing 10.

[0036] Preferably, the gear set 20 includes a first-stage gear set 210, a second-stage gear set 220, a third-stage gear set 230, and a fourth-stage gear set 240 that are engaged in sequence, and the power of the motor 11 is transmitted from the first-stage gear set 210 to the fourth-stage gear set 240 in sequence. The cooperation of multiple sets of gear sets can enable the motor to generate greater torque and have higher load capacity.

[0037] Please refer to Figure 9, preferably, a worm 12 is provided on the output shaft of the motor 11, and the first-stage gear set 210 includes a worm gear, a first-stage gear B 212, and a first-stage adjusting sleeve 213; there are 3-5 helical teeth on the worm 12 meshing with the worm gear, and the meshing position is in the middle of the worm 12; the first-stage gear B 212 meshes with the internal teeth of the worm gear; the first-stage adjusting sleeve 213 is located on one side of the worm gear; one installation shaft 21 passes through the worm gear, the first-stage gear B, and the first-stage adjusting sleeve. The first-stage gear B 212 is inserted into the worm gear, and the worm gear can drive the first-stage gear B 212 to rotate. The power transmission direction of this embodiment is motor 11 → first-stage gear set 210 → second-stage gear set 220 → third-stage gear set 230 → fourth-stage gear set 240. Among them, a worm 12 is provided on the output shaft of the motor 11, and the first-stage gear set 210 has a worm gear, and the worm gear meshes with the worm 12, having the functions of self-locking and reverse rotation. The worm 12 initially has a head, a middle part, and a tail. There are 3-5 helical teeth 13 on the middle part of the worm 12 meshing with the first-stage gear set 210, that is, the remaining tail of the worm 12 can be cut off. Therefore, the worm 12 can be shorter, having better bending resistance and being able to withstand greater forces. In addition, the middle part of the worm 12 can also not be cut off. As long as the middle part of the worm 12 is stressed, it does not affect the use. When the worm 12 is cut short, the occupied space of the worm 12 can be reduced, which is beneficial to the layout of the internal components of the chain window opener and to avoid interference, and more components can be assembled.
