specific Embodiment approach 1

[0033] refer to Figure 6 , Figure 8 to Figure 10 , a gear box, including a box 1, a motor (not shown in the figure), a transmission gear set and a sector gear 3. The transmission gear set includes a rotating first-stage gear 22 driven by a motor, a second-stage gear 23 meshing with the first-stage gear 22 , and an output gear 21 meshing with the second-stage gear 23 . The sector gear 3 is used to mesh with the output gear 21 of the transmission gear set. The sector gear 3 includes an output shaft 31, an arc-shaped gear portion 32 with the output shaft 31 as the center of a circle, and a connecting portion 33 connecting the output shaft 31 and the arc-shaped gear portion 32. The arc-shaped gear portion 32 and the connecting portion 33 can be Form a fan-shaped surface hollowed out inside.

[0034] sector gear 3 can be driven in the first position (refer to Figure 8 ) and the second position (see Figure 10 ), when the sector gear 3 is in the first position, the end of on...

Abstract

The invention relates to a gear box which can be applied to bathroom products. The gear box comprises a box body, a motor, a transmission gear set and a sector gear, wherein the sector gear is used for being engaged with the output gear of the transmission gear set and driven between a first position and a second position to rotate; the sector gear comprises an output shaft, an arc-shaped gear part and a connecting part, the arc-shaped gear part takes the output shaft as the center of a circle, and the connecting part is connected with the output shaft and the arc-shaped gear part. The gear box adopts the sector gear, shortens the working radius, saves space, and is wide in application range and convenient to design and mount in practical application. Since the sector gear is matched with the relay transmission of the output gears and relay gears, the working radius is shortened, and the arc length of the arc-shaped gear part also can be shortened. The more relay gears is, the shorter arc length of the arc-shaped gear part is, and the smaller the overall space is.

Description

technical field [0001] The invention relates to the field of gear boxes, in particular to a gear box applicable to sanitary products and its application. Background technique [0002] With the development of modern technology, smart bathroom products emerge in endlessly, such as smart toilets. The smart toilet makes the seat and the upper cover automatically open or close through the built-in gear box of the toilet, refer to image 3 It is the connection mode between the output shaft 1 and the gear of the traditional gearbox. The working radius of the gearbox depends on the output stage gear. Since the distance R from the center of the output shaft 1 of the traditional gearbox to the upper cover 2 cannot be reduced (refer to figure 1 , figure 2 ), so that the traditional cover plate needs to reserve enough space for the flipping of the upper cover 2, so that the thickness of the cover plate cannot be reduced. refer to Figure 4 , it can be seen that the use of a gearbox...
