The utility model provides a motor with high coaxiality, which comprises an upper shell 1 and a lower shell 2 which are combined to form a whole, wherein the inside of the whole is of a cavity structure;

the cavity structure is sequentially provided with a driving motor 11 and at least one stage of planetary gear train 200, and an output shaft of the driving motor 11 is coaxially provided with a driving gear which forms a sun gear of the planetary gear train 200;

the planet carrier of the planetary gear train 200 is coaxially provided with an output shaft 3;

the cavity structure is provided with a gear ring engaged with the planet gears of the planetary gear train 200.

Referring to the structure shown in fig. 1, the upper casing 1 and the lower casing 2 are connected to form a cavity structure, and the cavity structure includes a driving motor 11 and a speed reducing mechanism;

in an alternative embodiment of the reduction mechanism, the reduction mechanism is composed of at least one stage of planetary gear train 200 (refer to the planetary gear train 200 structure shown in fig. 2), an output shaft of the driving motor 11 in the cavity structure is engaged with the planetary gears of the planetary gear train 200 through a driving gear, the driving gear serves as a sun gear of the planetary gear train 200, in order to ensure the transmission efficiency of the planetary gear train 200, a gear ring matched with the planetary gears of the planetary gear train 200 is further arranged in the cavity structure, so that the transmission efficiency of the planetary gear train 200 is ensured;

when the speed reducing mechanism adopts a transmission mode of a planetary gear train, the coaxiality of the output shaft of the driving motor 11 and the output shaft 3 can be ensured, so that the speed reducing motor with high coaxiality is provided.

Further, the cavity structure is further provided with a connecting assembly for limiting the degree of freedom of the driving motor 11 along the axial direction of the output shaft 3.

In the actual use process, if the driving motor 11 is not limited, the motor may jump along the axial direction of the output shaft 3 if the motor works for a long time, and after a certain accumulated time, the driving motor 11 falls off from the planetary gear train 200, resulting in failure of the final structure of the motor with high coaxiality.

Therefore, the connecting assembly is required to be additionally arranged to limit the driving motor 11, and the driving motor 11 is prevented from jumping.

The planetary gear train 200 is two-stage or three-stage in sequential transmission connection along the axial direction of the output shaft 3.

Referring to the structures shown in fig. 3 and 4, fig. 3 illustrates a structure in which two stages of planetary gear trains 200 are mutually driven, and fig. 4 illustrates a structure in which three stages of planetary gear trains 200 are mutually driven (the number of stages of the planetary gear trains 200 corresponds to different reduction ratios, that is, the final output torque of the driving motor 11 at the output shaft 3 is correspondingly increased, the planetary gear trains 200 with fewer stages do not affect the output torque of the driving motor 11 and transmit the output torque to the output shaft 3. the planetary gear trains 200 with multiple stages improve the final output torque after the driving motor 11 outputs to the output shaft 3, and at the same time, the planetary gear trains 200 with larger accommodating cavity structures correspond to each other, and the motor with higher coaxiality is not affected to work).

The connecting assembly is a gasket 100, which is arranged at one end of the lower casing 2 close to the upper casing 1, and the driving motor 11 is fixedly connected with the lower casing through a screw.

In a specific alternative embodiment of the connection assembly, referring to the structure shown in fig. 5, the gasket 100 is disposed at the upper end of the lower housing 2, and the driving motor 11 is disposed at the upper end of the gasket 100 and fixed thereto by screws, so as to achieve a working condition of preventing the driving motor 11 from jumping.

A plurality of ventilation holes for heat exchange between the driving motor 11 and the outside are sequentially formed in the upper shell 1.

This driving motor that axiality is high simplifies the model and is: the output torque of the drive motor 11 is amplified by the planetary gear train 200, and finally, the torque is output at the output shaft 3. Under the long-time operation of driving motor 11, driving motor 11 will generate heat, if only put driving motor 11 directly into accommodation space, driving motor 11's radiating effect is relatively poor, long-time work, probably leads to driving motor 11's life to reduce.

Therefore, the upper housing 1 is provided with a plurality of ventilation holes, and the ventilation holes can accelerate the heat exchange process between the driving motor 11 and the outside air, and help the heat dissipation of the driving motor 11.

A sealing ring is arranged at the joint of the gasket 100 and the driving motor 11.

Because the upper shell 1 is provided with the vent hole for exchanging heat with the outside, impurities in the outside air may flow into the space between the gasket 100 and the lower shell 2, so that dust is in the planetary gear train 200 in the lower shell 2, and the engagement process of the planetary gear train 200 and the inner gear ring on the lower shell 2 is not facilitated after the impurities enter.

Therefore, a sealing ring is additionally arranged at the joint of the gasket 100 and the lower shell 2, so that dust is prevented from entering the planetary gear train 200 to a certain extent, and the transmission efficiency is reduced.

The angle feedback device 4 is positioned on the outer side of the lower shell 2 and communicated with the cavity structure, a rotating tooth 42 and a potentiometer 43 are accommodated in the angle feedback device 4, and a power output tooth 41 meshed with the rotating tooth 42 is positioned in the cavity structure and is coaxially arranged with the output shaft 3.

When the output shaft 3 outputs torque, if the output shaft does not have the angle control function (angle feedback), in the actual use process, the motor also needs to be matched with a related position sensor, and finally the controller can realize the closed-loop control of the angle of the motor, which is very inconvenient.

Therefore, the angle feedback device 4 is additionally arranged, the signal end of a potentiometer 43 in the angle feedback device 4 is connected with the rotating teeth 42, when the rotating teeth 42 rotate, the potentiometer 43 feeds back the number of rotating turns/turns of the rotating teeth 42 to the controller, the power output teeth 41 meshed with the rotating teeth 42 are coaxially arranged with the output shaft 3, and after the potentiometer 43 can obtain the angle information of the rotating teeth 42, the transmission ratio of the power output teeth 41 and the rotating teeth 42 is a certain value. Finally, the feedback of the rotation angle of the output shaft 3 can be realized.

The power output tooth 41 is provided coaxially with the carrier of the planetary gear train 200 at the stage closest to the output shaft 3.

When the planetary gear train 200 is multi-stage, the power output gear 41 can only be located below the planetary gear train 200 at the lowest stage and is coaxially arranged with the planetary gear train 200 at the lowest stage, that is: the power output tooth 41 and the output shaft 3 are coaxially arranged, the rotation angle of the output shaft 3 feeds back the rotation angle of the power output tooth 41, and finally, the power output tooth 41 is meshed with the rotation tooth 42 to realize closed-loop control of the rotation angle of the motor.

The planetary gear of the planetary gear train 200 of the same stage is any one of a helical gear, a helical cylindrical gear and a cylindrical gear.

As the specific gear type adopted by the planetary gear trains 200, the planetary gear trains 200 at the same stage must be helical gears or helical cylindrical gears or cylindrical gears of the same type, and the planetary gears of the planetary gear trains 200 at different stages can be of different types (for example, the planetary gear trains 200 at the first stage adopt cylindrical gears, the planetary gear trains 200 at the second stage adopt helical cylindrical gears, and only the planetary carrier of the planetary gear train 200 at the first stage is connected with gears meshed with the helical cylindrical gears of the planetary gear trains 200 at the second stage, the planetary gear trains 200 at the first stage can adopt cylindrical gears, the planetary gear trains 200 at the second stage can adopt helical cylindrical gears, and the operation process of the motor is not influenced).

The utility model provides an intelligent closestool, includes base, lid and foretell motor that axiality is high, and the base is articulated with the lid, and the output shaft and the lid transmission of motor link to each other, and when the lid closed, the lid was in order to be parallel and level with the up end of base.

The motor with high coaxiality can be used on the intelligent closestool, and the traditional passive cover body structure is changed into the active cover body structure through the transmission connection of the motor and the cover body of the closestool so as to deal with some special conditions.

The motor with high coaxiality adopts a planetary gear structure, has compact structure and stable operation, has a volume far smaller than that of the existing flip motor, and is beneficial to installation; the planetary gear structure of the motor with high coaxiality operates stably, and the flip position angle is positioned accurately.

Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
