DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example:

[0018] A miniature highly integrated vehicle sunroof roller blind electric actuator, such as Figure 1 As shown, it includes a driving motor 1, a rolling shutter synchronous wheel 3 and a rolling shutter drum 5. The output end of the driving motor 1 is connected to a planetary reducer 2, which is integrated into the rolling shutter synchronous wheel 3. The output end of the planetary reducer 2 is fixedly connected to a rolling shutter synchronous inner tube 4. The rolling shutter synchronous inner tube 4 is rotatably connected to the rolling shutter drum 5 through a bearing, and a preload spring 6 is provided between the rolling shutter synchronous inner tube 4 and the rolling shutter drum 5.

[0019] In this embodiment, the planetary reducer 2 includes a first-stage planetary assembly 21, which is fixedly connected to the output end of the drive motor 1. A second-stage planetary assembly 22 is provided at the end of the first-stage planetary assembly 21 away from the drive motor 1, and the second-stage planetary assembly 22 is fixedly connected to the rolling shutter synchronous wheel 3.

[0020] In this embodiment, if Figure 2As shown, the first-stage planetary assembly 21 includes a first-stage sun gear 211 and a first-stage outer gear ring 215 of a planetary reducer. The first-stage sun gear 211 is fixedly connected to the output shaft of the driving motor 1. The first-stage sun gear 211 is meshedly connected with three first-stage planetary gears 212. The first-stage planetary gears 212 are rotatably connected to a first-stage gear rack 213 through bearings. The end of the first-stage gear rack 213 away from the driving motor 1 is connected to a first-stage planetary output shaft 214. The first-stage outer gear ring 215 of the planetary reducer is provided with a first-stage planetary fixed outer ring gear 216 on the inner side. The first-stage planetary fixed outer ring gear 216 is meshedly connected with the first-stage planetary gears 212. The first-stage outer gear ring 215 of the planetary reducer is fixedly connected to the driving motor 1. The first-stage outer gear ring 215 of the planetary reducer is rotatably connected to the first-stage planetary output shaft 214 through bearings.

[0021] In this embodiment, if Figure 3 As shown, the secondary planetary assembly 22 includes a secondary sun gear 221, which is fixedly connected to the primary planetary output shaft 214, and the secondary sun gear 221 is meshedly connected to the secondary planetary gear 222, and the secondary planetary gear 222 is meshedly connected to the outer rotor output shaft 223, and the inner side of the outer rotor output shaft 223 is provided with a secondary planetary outer rotor outer ring gear, and the outer rotor output shaft 223 is rotatably connected to the primary planetary assembly 21 through a bearing, and the outer rotor output shaft 223 is fixedly connected to the rolling shutter synchronous wheel 3, and the outer rotor output shaft 223 is fixedly connected to the rolling shutter synchronous inner tube 4.

[0022] In this embodiment, a first-stage planetary gear frame fixing screw 7 is also included, and the first-stage outer gear ring is fixedly connected to the drive motor 1 through the first-stage planetary gear frame fixing screw 7.

[0023] In this embodiment, it also includes a rolling curtain synchronous inner tube fixing screw 8, and the outer rotor output shaft 223 is fixedly connected to the rolling curtain synchronous inner tube 4 through the rolling curtain synchronous inner tube fixing screw 8.

[0024] Working principle:

[0025] The drive motor 1 is composed of a motor housing, front and rear end covers of the motor, a motor stator core, a motor rotor core, a motor stator winding, a motor rotor permanent magnet, and a motor output shaft. The motor stator core is a tooth slot structure, and the motor winding is wound on the tooth slot. The working principle is based on the law of electromagnetic induction. When the stator winding is energized, a rotating magnetic field is generated. This magnetic field interacts with the magnetic field of the rotor permanent magnet to generate a torque, thereby rotating the rotor.

[0026] The vehicle sunroof roller blind system is composed of a roller blind synchronous wheel 3, a cloth curtain rolling shaft, a roller shaft synchronous inner tube 4, and a pre-tension spring 6 between the cloth curtain rolling shaft and the roller shaft inner synchronous inner tube. The synchronous wheel is provided with a synchronous belt to drive the extension and retraction of the cloth curtain. The synchronous wheel and the roller shaft inner synchronous inner tube are integrated, and the roller shaft inner synchronous inner tube transfers the driving torque to the other side of the roller blind to achieve torque balance on both sides of the roller blind. The two ends of the pre-tension spring 6 between the cloth curtain rolling shaft and the roller shaft inner synchronous inner tube are respectively connected to the cloth curtain rolling shaft and the roller shaft inner synchronous inner tube. Through the pre-tension force of the pre-tension spring 6, the cloth curtain rolling shaft can have enough force to tighten the cloth curtain.

[0027] The output shaft of the driving motor 1 and the rolling shutter synchronous wheel 3 are connected by a two-stage planetary reducer 2 for torque transmission. The first-stage sun gear 211 of the planetary reducer 2 is installed on the output shaft of the driving motor 1 rotor, and the first-stage sun gear 211 drives the first-stage planetary gear 212 to rotate through the motor rotor shaft. The first-stage sun gear 211 drives the first-stage planetary gear 212 to rotate. The first-stage planetary gear 212 is meshed with the outer gear ring of the first-stage reducer. The outer gear ring of the first-stage reducer is fixedly connected to the front end cover of the stator of the driving motor 1, and the first-stage planetary gear will rotate around the first-stage sun gear 211. The first-stage planetary gear 212 frame is connected to the first-stage planetary gear shaft through an oil-containing bearing. The first-stage planetary gear will rotate around the first-stage sun gear 211, which will drive the first-stage planetary gear 212 frame to rotate and output the first-stage planetary reduction torque.

[0028] The secondary sun gear 221 of the planetary reducer 2 is mounted on the primary planetary output shaft 214, and is connected by a D-shaped shaft hole. The primary planetary output shaft 214 drives the secondary planetary sun gear to rotate, and the secondary planetary sun gear drives the secondary planetary gear 222 to rotate. The secondary planetary gear 222 is meshed with the secondary reducer gear ring 224, and the secondary reducer gear ring 224 is connected to the output shaft. The secondary reducer inner gear ring is fixedly connected to the rolling curtain system synchronous wheel, and the side of the secondary reducer inner gear ring is also fixedly connected to the rolling curtain synchronous inner tube 4. Since the primary planetary gear 212 frame is a fixed part, the secondary planetary gear will rotate with the secondary sun gear 221, and the secondary planetary gear shaft and the primary planetary gear 212 frame are fixed. The secondary planetary gear is meshed with the secondary reducer inner gear ring, so that the secondary reducer inner gear ring performs a reduced rotation motion.

[0029] The inner gear ring of the secondary reducer is fixedly connected to the synchronous wheel of the rolling curtain system, and the side surface of the inner gear ring of the secondary reducer is also fixedly connected to the synchronous inner tube 4 of the rolling curtain. When the output torque of the driving motor 1 passes through the secondary reducer, its torque is transmitted to the synchronous wheel of the rolling curtain system and the synchronous inner tube 4 of the rolling curtain. The synchronous wheel of the rolling curtain system and the synchronous inner tube 4 of the rolling curtain simultaneously output torque and synchronous speed.

[0030] The curtain roller and the curtain synchronous inner tube 4 are connected by a preload spring 6, and the two ends of the preload spring are respectively connected to the curtain roller and the curtain synchronous inner tube 4. In order to ensure that the curtain roller and the curtain synchronous inner tube 4 can slide relative to each other, a bearing is installed between the two. The rotation of the curtain synchronous inner tube 4 will drive the curtain roller through the preload spring 6. At the same time, due to the existence of the preload spring 6, the curtain of the sunroof roller curtain is always in a taut state, so that the sunroof electric roller curtain system can work normally.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
