As shown in Figures 1 to 4, gear-box 100 of the present invention in order to be connected with the employed power output unit of intelligent closestool, drives the ring or the cover plate folding of intelligent closestool, the housing 20 that comprises gear train 10 and accommodate this gear train.In gear-box 100 of the present invention, this power output unit is a drive motor 24.
See also shown in Fig. 1,2, described gear train 10 comprises first gear 11, second gear 12, the 3rd gear 13, the 4th gear 14 and the 5th gear 15 that is combined together successively, wherein first gear 11 is as power input gear, be connected with drive motor 24, and the 5th gear 15 is a power output gear, with the intelligent closestool associated component, connect as cover plate or ring.
Wherein first gear 11 includes axle sleeve dish 110 and setting gear 111 thereon, and this gear 111 is a helical gear in the mode of execution shown in Fig. 1,2, fixes with the output shaft of drive motor 24.Second, third, the 4th gear the 12,13, the 14th, the middle transition gear is for duplicate gear designs.Second gear 12 includes transmission shaft 120 and is docile and obedient preface setting gearwheel 121 and small gear 122 thereon.The 3rd gear 13 includes transmission shaft 130 and is docile and obedient preface setting gearwheel 131 and small gear 132 thereon.The 4th gear 14 includes transmission shaft 140 and is docile and obedient preface setting gearwheel 141 and small gear 142 thereon.The 5th gear 15 includes transmission shaft 150 and setting gear 151 thereon.For second, third, in the 4th gear 12,13, the 14 duplicate gears designs, the big small gear that relates to, according to its present position on transmission shaft, it also can be to be called external gear and internal gear.And in different mode of executions, the size of external gear and internal gear is not limited to external gear dimensionally necessarily greater than internal gear.
As shown in Fig. 1,2, since gear train 10 employed second, third, the duplicate gear design of the 4th gear 12,13,14, first, second, third gear 11,12,13 that makes gear train 10 comprise spatially becomes vertically to be provided with, and the 3rd, the 4th, the 5th gear 13,14,15 spatially becomes cross setting.So be provided with, for the whole vertically upper and lower settings modes of the gear of the existing gear train that uses, the gear train structure is compact more, and space layout is more reasonable, and volume is littler relatively, can better satisfy the requirement of intelligent sanitaryware for volume.Accordingly, be in the gear of different gear stages in the gear train 10, just do not need to be provided with the transmission shaft 110,120,130,140,150 that runs through whole space lengths, but can be by housing 20 designs, the length of each transmission shaft can be shortened accordingly, and then the space hold of gear train can be further reduced.
Further, gear-box 100 of the present invention also comprises the housing 20 of taking in gear train 10.For the design of existing employed former and later two housings of gear train.The employed housing of the gear train that the present invention relates to is then according to its unique space layout, three housings 21,22,23 before, during and after including, and, gear train 10 is contained in it by in the middle of the middle shell 22 the enclosure interior space segmentation being become first, second host cavity 210,230.
Please in conjunction with shown in Fig. 3,4, in one of the present invention preferred embodiment, at first, first, second, third gear 11,12,13 of described gear train 10 is positioned at first host cavity 210, and wherein the two ends of the transmission shaft 120,130 of second, third gear 12,13 are installed in respectively on preceding, the middle shell 21,22.Secondly, the two ends of the transmission shaft 140 of the 4th gear 14 are installed in respectively on the forward and backward housing 21,23, and wherein the gearwheel 141 of the 4th gear 14 is positioned at first host cavity 210, and small gear 142 is positioned at second host cavity 230.Once more, the 5th gear 15 is positioned at second host cavity 230.During the two ends of its transmission shaft 150 are installed on respectively, on the rear case 22,23.Be provided with like this, can be so that gear train 10 can compact effectively be allocated in the housing of gear-box 100.With respect to prior art, gear-box 100 of the present invention has not only effectively been saved the unnecessary length of arranging and producing because of single on vertically arranging, and the transmission shaft that also overcomes gear train on laterally arranging need run through whole containing space and the defective that causes width to reduce.
Further, in other embodiments, housing of the present invention only be not limited to by before, during and after three housings form, it also can be made up of former and later two housings, for example, middle shell combined with front case or rear case gets final product.But same, include the front and back arrangement mode owing to be contained in the space arrangement mode of the gear of the gear train in it, therefore make specific one or more gear only can be positioned at the space that rear case surrounds, saved the space.
In other embodiments, the included gear quantity of the gear train that the present invention relates to does not limit, but it all can comprise two space arrangement modes: be arranged above and below longitudinally and horizontal front and back arrangement mode.For example, be example with 3 gears, wherein second gear designs for duplicate gear.It cooperates up and down for first, second gear spatially becomes vertically, and second, third gear spatially becomes horizontal front and back to cooperate.Realized the gear train compact structure equally, rationally distributed, the purpose that shared volume is less relatively.
Further, as shown in Figure 3, the drive motor 24 that cooperates with first gear 111 of gear-box 100 and second host cavity 230 are set up in parallel and are positioned at the below of its this second host cavity 230, be positioned at the rear of first host cavity 210 simultaneously, spatially become the mode that vertically is arranged above and below with the 5th gear 15, so, make that whole gear-box 100 space layouts are more reasonable, structure is compact more, and shared volume is littler.
The gearwheel 121 of first gear 111 that the gear train 10 that further, the present invention relates to comprises and second gear 12 that cooperates with it designs for helical gear.It is good that helical gear has a meshing performance; Stable drive is impacted for a short time, and noise is little; Contact ratio is big, and bearing capacity is than advantages such as height.And the gear train that the present invention relates to also only uses this a pair of helical gear to carry out power transmission, and employed many for helical gear transmission power with respect to existing gear train, it also can satisfy usage requirement fully.And,, also can further reduce the cost of the gear train that the present invention relates to owing to use the helical gear of alternative other positions of ordinary gear.
Really, gear train of the present invention also can be applied to other application that bathroom automatic field domestic demand drive motor drives.
Though disclosed the specific embodiment of the present invention above, they are not the limitations of the scope of the invention, know those skilled in the art person the above concrete modifications and variations of implementing is also contained within the scope of the present invention.
