Detailed implementation manners

[0024] The following further describes the detailed implementation manners of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these implementation manners is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] As Figures 1-9 shown, an overload-proof smart home buffer device includes a drive motor 1, a reduction gearbox 2, an internal gear ring 3, an end cover 4, and an output shaft 5. The drive motor 1 is arranged at one end of the reduction gearbox 2, and one end of the internal gear ring 3 is arranged at the other end of the reduction gearbox 2; the end cover 4 is arranged at the other end of the internal gear ring 3; a gear set 6 is arranged in the inner cavity of the reduction gearbox 2, and a planetary reducer 7 is arranged in the inner cavity of the internal gear ring 3; one end of the gear set 6 is connected to the output end of the drive motor 1, and the other end of the gear set 6 is connected to the planetary reducer 7; the output shaft 5 is arranged at the output end of the planetary reducer 7, and the output shaft 5 penetrates through the end cover 4; a potentiometer assembly 9 is arranged on the lower side of the planetary reducer 7, which can prevent the drive motor 1 from being locked and continuously outputting, resulting in a short circuit or even damage to the drive motor 1, improving the user experience and reducing the use cost.

[0026] In addition, the gear set 6 includes an overload protection gear 61 and a speed regulation gear 62. The overload protection gear 61 includes an external tooth 611 and an internal tooth 612. A number of limit snap rings 613 are arranged between the external tooth 611 and the internal tooth 612. In this embodiment, 3 limit snap rings 613 are used. In the normal state, the limit snap rings 613 transmit torque with the connection end. When the drive motor 1 is overloaded, the limit end 618 of the limit snap ring 613 is blocked by the limit platform 616, so that the installation gap between the limit snap ring 613 and the connection end 614 increases and the connection strength weakens, realizing a slipping phenomenon, thereby playing an overload protection role.

[0027] Furthermore, the internal tooth 612 is provided with a connection end 614, and a first transmission tooth 615 is arranged on one side of the connection end 614; the connection end 614 is arranged in the inner cavity of the external tooth 611.

[0028] In addition, a limit platform 616 is arranged in the inner cavity of the external tooth 611, and a second transmission tooth 617 is arranged on the outside of the external tooth 611.

[0029] Further, both ends of the limit snap spring 613 have limit ends 618, and the limit ends 618 at both ends are respectively arranged on both sides of the limit platform 616.

[0030] In addition, the speed regulation gear 62 includes a first gear 621 and a second gear 622. The first gear 621 and the second gear 622 are sequentially connected to the first transmission tooth 615, and the second gear 622 is connected to the planetary speed reducer 7 to increase the torque output of the speed reducer 2.

[0031] Further, the limit snap spring 613 is in interference fit with the connection end 614.

[0032] In addition, the drive motor 1 is provided with a housing 8 to prevent the drive motor 1 from being damaged by external forces.

[0033] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations to these embodiments still fall within the protection scope of the present invention.
