[0039] Similarly, when the input shaft 22 is connected with the planet gear 23 and drives the planet gear 23 to rotate, the first output shaft 24 is connected with the sun gear 21, and the second output shaft 26 is connected with the ring gear 25, when the sun gear 21 is fixed, the planet gear 23 can output power to the second output shaft 26 connected with the ring gear 25, and when the ring gear 25 is fixed, the planet gear 23 can output power to the first output shaft 24 connected with the sun gear 21; when the input shaft 22 is connected with the planet gear 23 and drives the planet gear 23 to rotate, the first output shaft 24 is connected with the ring gear 25, and the second output shaft 26 is connected with the sun gear 21, when the sun gear 21 is fixed, the planet gear 23 can output power to the first output shaft 24 connected with the ring gear 25, and when the ring gear 25 is fixed, the planet gear 23 can output power to the second output shaft 26 connected with the sun gear 21.
[0040] When the input shaft 22 is connected with the ring gear 25 and drives the ring gear 25 to rotate, the first output shaft 24 is connected with the sun gear 21, and the second output shaft 26 is connected with the planet gear 23, when the sun gear 21 is fixed, the ring gear 25 can output power to the second output shaft 26 connected with the planet gear 23, and when the planet gear 23 is fixed, the ring gear 25 can output power to the first output shaft 24 connected with the sun gear 21; when the input shaft 22 is connected with the ring gear 25 and drives the ring gear 25 to rotate, the first output shaft 24 is connected with the planet gear 23, and the second output shaft 26 is connected with the sun gear 21, when the sun gear 21 is fixed, the ring gear 25 can output power to the first output shaft 24 connected with the planet gear 23, and when the planet gear 23 is fixed, the ring gear 25 can output power to the second output shaft 26 connected with the sun gear 21.
[0041] Specifically, the sun gear 21, the planet gear 23, and the ring gear 25 can be fixed as power input and power output according to actual conditions, and the present disclosure does not make any limitation thereon, as long as one driving member 1 can be used to drive the window glass to rise and drive the sunshade curtain to move.
[0042] Further, one of the sun gear 21, the planet gear 23 and the ring gear 25 can be connected with the door body to fix one of the sun gear 21, the planet gear 23 and the ring gear 25, and then transmit power through the meshing transmission of the other two of the sun gear 21, the planet gear 23 and the ring gear 25.
[0043] Exemplarily, referring to Figure 2 As shown, the input shaft 22 is connected with the sun gear 21, the first output shaft 24 is connected with the planet gear 23, and the first output shaft 24 is provided with the first brake 27, the second output shaft 26 is connected with the ring gear 25, and the second output shaft 26 is provided with the second brake 28.
[0044] That is, when the first brake 27 is braked, the first output shaft 24 stops rotating, when the first brake 27 is released, the first output shaft 24 can rotate, when the second brake 28 is braked, the second output shaft 26 stops rotating, when the second brake 28 is released, the second output shaft 26 can rotate, the first output shaft 24 and the second output shaft 26 can be fixed separately or simultaneously through the first brake 27 and the second brake 28, and then the window glass lifting and the sunshade curtain driving can be controlled as needed.
[0045] Specifically, the driving member 1 is connected with the sun gear 21 and provides power to the sun gear 21, when the first brake 27 is braked and the second brake 28 is released, the first output shaft 24 is fixed, and the second output shaft 26 rotates under the driving of the sun gear 21, that is, the ring gear 25 can relatively rotate; when the first brake 27 is released and the second brake 28 is braked, the second output shaft 26 is fixed, and the first output shaft 24 rotates under the driving of the sun gear 21, that is, the planet gear 23 can relatively rotate, that is, the asynchronous motion of the window glass and the sunshade curtain can be realized through the switching of the working states of the first brake 27 and the second brake 28.
[0046] In specific implementation, the first brake 27 includes a first brake part and a second brake part, the first brake part is connected with the first output shaft 24, the second brake part is used to be connected with the door body, and the first brake part and the second brake part can be connected to fix the first output shaft 24 relative to the door body, or can be separated to make the first output shaft 24 rotate. It can be understood that, since the second brake part is connected with the door body, when the first brake part is connected with the second brake part, the first brake part can be fixed relative to the door body, and then the first output shaft 24 does not rotate, when the first brake part is separated from the second brake part, the first output shaft 24 can rotate under the driving of the input shaft 22.
[0047] The second brake 28 comprises a third brake part connected with the second output shaft 26 and a fourth brake part connected with the door body, and the third brake part and the fourth brake part can be connected to fix the second output shaft 26 relative to the door body or can be separated to rotate the second output shaft 26. It can be understood that, since the fourth brake part is connected with the door body, when the third brake part is connected with the fourth brake part, the third brake part can be fixed relative to the door body, so that the second output shaft 26 does not rotate; when the third brake part is separated from the fourth brake part, the second output shaft 26 can rotate under the drive of the input shaft 22.
[0048] Specifically, when the first brake 27 is braked and the second brake 28 is released, the first output shaft 24 connected with the first brake 27 is fixed relative to the door body, and the second output shaft 26 connected with the second brake 28 can rotate, at this time, the sun gear 21 is connected with the driving member 1, and the input shaft 22 can drive the second output shaft 26 as an input shaft to output power through the driving of the ring gear 25; when the first brake 27 is released and the second brake 28 is braked, the first output shaft 24 connected with the first brake 27 can rotate, and the second output shaft 26 connected with the second brake 28 is fixed relative to the door body, at this time, the sun gear 21 is connected with the driving member 1, and the input shaft 22 can drive the first output shaft 24 as an input shaft to output power through the driving of the planet wheel 23, that is, the user can brake or release the first brake 27 and the second brake 28 according to actual needs, and through the cooperation of the first brake 27 and the second brake 28, the asynchronous movement of the window glass and the sunshade curtain can be realized.
[0049] In some embodiments, the driving mechanism of the present disclosure can also realize the synchronous movement of the window glass and the sunshade curtain, specifically, the third brake 29 is arranged between the planet wheel 23 and the ring gear 25, and the third brake 29 comprises a fifth brake part and a sixth brake part, and the fifth brake part and the sixth brake part can be connected to make the planet wheel 23 and the ring gear 25 rotate synchronously, or can be separated to make the planet wheel 23 and the ring gear 25 rotate respectively. It can be understood that, under the condition that the first brake 27 and the second brake 28 are both released, the planet wheel 23 and the ring gear 25 can both rotate, when the fifth brake part and the sixth brake part are connected, the planet wheel 23 and the ring gear 25 are fixed together, and under the driving of the sun gear 21, the planet wheel 23 and the ring gear 25 can both rotate, thereby driving the first output shaft 24 and the second output shaft 26 to rotate synchronously, so as to realize the synchronous movement of the window glass and the sunshade curtain, specifically, the transmission ratio between the planet wheel 23 and the ring gear 25 and the sun gear 21 is one to one at this time, that is, the window glass and the sunshade curtain can move at the same speed.
[0050] Further, when the fifth brake portion and the sixth brake portion are separated, the planetary gear 23 and the ring gear 25 can rotate respectively, and further, one of the planetary gear 23 and the ring gear 25 can be fixed and the other can rotate to output power under the cooperation of the first brake 27 and the second brake 28.
[0051] Of course, it should be noted that the driving member 1 can also be connected with the planetary gear 23 and the ring gear 25 to make the planetary gear 23 and the ring gear 25 as power input, and the present disclosure does not limit this, as long as the arrangement positions of the first brake 27, the second brake 28 and the third brake 29 can be reasonably arranged to realize the synchronous or asynchronous movement of the window glass and the sunshade curtain.

It can be understood that, as shown in Figure 2 The center of the sun gear 21, the center of the ring gear 25 and the center of the plurality of planetary gears 23 are on a straight line, and further, the sun gear 21, the planetary gear 23 and the ring gear 25 can be meshed and transmitted, and further, one of the sun gear 21, the planetary gear 23 and the ring gear 25 can drive the other two to rotate. Specifically, the number of planetary gears 23 can be set according to actual conditions, and the present disclosure does not limit this, as long as it can be meshed with the sun gear 21 and the ring gear 25 to transmit power. Further, the first output shaft 24 and the second output shaft 26 are separately arranged on both sides of the sun gear 21 to avoid interference.
[0053] Referring to Figure 1 The driving mechanism provided by the present disclosure further comprises a first gear box 4, the first gear box 4 is connected with the first output shaft 24, that is, the first output shaft 24 can output power to the first gear box 4, so that the first output shaft 24 can drive the sunshade curtain rotating shaft to rotate through the first gear box 4, and further, the first gear box 4 can also obtain a preset sunshade curtain movement speed. When specifically implemented, the first gear box 4 is arranged in the motor cover of the sunshade curtain to prevent impurities such as dust and water vapor from entering the first gear box 4.

When specifically implemented, the second gear box 5 is arranged in the motor housing of the window glass, so as to prevent impurities such as dust and water vapor from entering the second gear box 5.

[0056] Of course, it needs to be explained that the transmission gear set can also be a transmission gear set composed of a fixed shaft gear train, and the present disclosure does not limit this, as long as two output shafts can be arranged on the same or different moving gears or gear shafts, and a brake or a synchronizer is arranged at a suitable position, so that the two output shafts can drive the window glass and the sunshade curtain to move, respectively.
