The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Example 1

[0031] like Figure 1 , Figure 3 As shown, a speed reduction drive device includes a motor 1, a speed reduction assembly 2, a bottom shell 3 with an upper opening, and a top cover 4.

[0032] The reduction assembly 2 includes a worm 21, a worm wheel 22 made of plastic material, a pinion 23 and a gear 24. The pinion 23 includes an upper shaft 231, a journal 232 and a lower shaft 233. The journal 232 and the worm wheel 22 are fixedly connected. The worm 21, the pinion 23 and the gear 24 are made of metal material.

[0033] The bottom shell 3 includes a circular fixing seat 31, a through hole 32 and a shaft seat 33 provided on a wide wall plate in the width direction. The circular fixing seat 31 is provided with an arc-shaped head 311 and is connected to a long wall plate in the length direction of the bottom shell 3.

[0034] The wide end plate of the top cover 4 in the width direction is provided with an arc-shaped groove 41;

[0035] The motor shaft is fixed to the worm gear 21, and the motor 1 is fixed to the circular fixed seat 31. The shaft head of the worm gear 21, which is suspended from the ground, is rotatably engaged with the shaft seat 33. The top cover 4 and the bottom shell 3 are fastened together, with the arc-shaped slot 41 and the arc-shaped head 311 fastening together. One end of the long wall plate of the bottom shell 3 is attached to the end of the circular fixed seat 31. The upper shaft body 231 and the lower shaft body 233 are rotatably engaged with the top cover 4 and the bottom shell 3, respectively. The output shaft 241 and the lower shaft head 242 of the large gear 24 are rotatably engaged with the top cover 4 and the bottom shell 3, respectively. The output shaft 241 extends out of the top cover 4. The worm gear 21 meshes with the worm wheel 22, and the small gear 23 meshes with the large gear 24 for speed reduction. The axis of the worm gear 21 is perpendicular to the axis of the worm wheel 22. The worm gear is made of metal, and the worm wheel is made of plastic, which effectively reduces noise during operation. The worm gear and the worm wheel are in the same plane, resulting in a large transmission ratio and a compact structure.

[0036] As a further improvement of this utility model: the neck 232 is polygonal or gear-shaped;

[0037] The neck 232 is pre-embedded on the worm gear 22.
