[0047] See also Figure 1 and Figure 3 , is a partial structural diagram of a sunshade assembly 100 shown in an embodiment of the present application. The components not shown also include at least a timing belt, a slider and a curtain. The specific installation relationship and working principle are explained below.

[0048] Exemplarily, the sunshade assembly 100 includes a driver 10, a reducer 20, a transmission member 30, and a reel mechanism 40. The reducer 20 is connected to the driver 10 in a transmission manner, and the reducer 20 is connected to the transmission member 30 in a transmission manner, and the transmission member 30 is arranged on a side of the reducer 20 away from the driver 10; the reel mechanism 40 is connected to the reducer 20 in a transmission manner, and the reel mechanism 40 is arranged on a side of the reducer 20 away from the driver 10, and the transmission member 30 is arranged at the end of the reel mechanism 40.

[0049] Preferably, the driver 10, the reducer 20, the transmission member 30 and the reel mechanism 40 are coaxially arranged. Such an arrangement makes the assembly arrangement of the four components regular and compact, small in size, and occupies less space, while being conducive to shortening the power transmission path and improving the power output efficiency.

[0050] Furthermore, a receiving groove 31 is formed in a recessed manner on the side of the transmission member 30 facing the driver 10 , and at least a portion of the reducer 20 is disposed in the receiving groove 31 .

[0051] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: in the sunshade assembly 100 of this solution, the driving force output by the driver 10 can be simultaneously output to the transmission member 30 and the reel mechanism 40 after being decelerated and torqued by the reducer 20, so that the transmission member 30 and the reel mechanism 40 can rotate synchronously, thereby driving the curtain installed with the two to unfold or retract, thereby realizing the sunshade function of the sunshade assembly 100; among them, on the one hand, the power source formed by the driver 10 and the reducer 20 is simultaneously connected to the transmission member 30 and the reel mechanism 40 for transmission, which reduces the driver 1 0, which simplifies the structural composition of the sunshade assembly 100 and improves the integration level of the sunshade assembly 100; on the other hand, by providing a receiving groove 31 on the transmission member 30, while the reducer 20 is connected to the transmission member 30 for transmission, at least part of the structure of the reducer 20 can be built into the receiving groove 31, thereby improving the integration level of the reducer 20 and the transmission member 30, and further helping to reduce the overall volume of the sunshade assembly 100, realize a miniaturized design, and reduce the installation space required for the sunshade assembly 100, thereby reducing the impact on the glass lighting area.

[0052] Please continue reading Figure 1 In one embodiment, the driver 10 includes a driving motor. The driving motor has low cost, is easy to maintain, and has stable power output. Of course, in other optional embodiments, the driver 10 can also be other types of driving devices, which can be flexibly selected according to actual needs.

[0053] In this embodiment, the driving motor includes a motor housing 11, a stator assembly 12, a rotor assembly 13 and a position detection assembly 14. The stator assembly 12 is fixed on the inner wall of the motor housing 11, the rotor assembly 13 is rotatably arranged in the motor housing 11 and penetrates the interior of the stator assembly 12, and the position detection assembly 14 is arranged in the motor housing 11 and cooperates with the rotor assembly 13.

[0054] Among them, the motor housing 11 is a load-bearing main component, which is used to load the integrated stator assembly 12, the rotor assembly 13 and the position detection assembly 14. When working, the stator assembly 12 is energized, and the stator assembly 12 immediately generates a rotating magnetic field, which interacts with the magnetic field of the rotor assembly 13 to generate a torque, thereby driving the rotor assembly 13 to rotate, and outputting a rotating driving force to the reducer 20 through the rotor assembly 13. In this process, the position detection assembly 14 detects the rotor magnetic pole position of the rotor assembly 13 to improve the power output accuracy; in addition, by detecting the position of the rotor magnetic pole in real time, the motor control system can more accurately control the operating state of the drive motor, thereby improving the control accuracy of the drive motor; furthermore, accurate rotor magnetic pole position detection helps to ensure that the drive motor operates in the best state, reduce energy loss, and improve operating efficiency; finally, through real-time monitoring and feedback, abnormal conditions in the operation of the drive motor can be discovered in time, so that corresponding measures can be taken in time to protect the drive motor from damage and extend its service life.

[0055] Specifically, the rotor assembly 13 is connected to a motor shaft 15, which is arranged between the rotor assembly 13 and the reducer 20. One end of the motor shaft 15 close to the reducer 20 extends to the outside of the motor housing 11 and is transmission-connected to the reducer 20. When the rotor assembly 13 rotates under the action of the magnetic field torque, the rotational power can be transmitted to the reducer 20 through the motor shaft 15, thereby outputting the rotational torque to the reducer 20.

[0056] Please continue reading Figure 1 In an optional embodiment, the stator assembly 12 includes a stator core 121 and a stator winding 122 installed on the outside of the stator core 121, the rotor assembly 13 includes a rotor core 131 and a rotor permanent magnet 132 installed on the outside of the rotor core 131, and the rotor permanent magnet 132 is arranged in cooperation with the position detection assembly 14.

[0057] The stator core 121 is used to load and fix the stator winding 122. For example, a tooth slot structure is provided on the outer periphery of the stator core 121, and the stator winding 122 is wound in the tooth slot structure. The installation method is simple, the stability is good, and a large number of stator windings 122 can be installed, which helps to strengthen the strength of the magnetic field generated by the stator assembly 12 and improve the power output performance of the drive motor. The rotor permanent magnet 132 installed on the outside of the rotor core 131 can also generate a magnetic field, which interacts with the magnetic field generated by the stator winding 122 to generate a torque that drives the rotor assembly 13 to rotate. The position detection component 14 detects the position of the rotor permanent magnet 132 to accurately control the output torque of the drive motor.

[0058] Please continue reading Figure 1In an optional embodiment, the position detection component 14 includes a mounting bracket 141 , a Hall circuit board 142 and a Hall sensor 143 . The Hall circuit board 142 is mounted on the motor housing 11 through the mounting bracket 141 , and the Hall sensor 143 is disposed on the Hall circuit board 142 .

[0059] The rotor permanent magnet 132 has a protruding portion 132 a extending out of the side surface of the stator core 121 along the first direction of the sunshade assembly 100 , and the Hall sensor 143 is arranged on a side of the protruding portion 132 a away from the stator assembly 12 .

[0060] The first direction is specifically Figure 2 The direction of the arrow S.

[0061] It should be noted that in other optional embodiments, the Hall sensor 143 may also be replaced by any one of a rotary transformer, a photoelectric encoder, an open-circuit transformer, etc.

[0062] In the present application, the motor housing 11 is specifically composed of a front cover, a rear cover and an annular shell body, and the front cover and the rear cover are respectively sealed and installed at the two axial opening ends of the shell body, and the installation method can be at least one of screw connection, welding, riveting, bonding, etc. In addition, the middle of the front cover and the rear cover are provided with mounting holes, and bearings are installed in the mounting holes, and the bearings are used for rotating and assembling with the end shaft of the rotor assembly 13.

[0063] The mounting bracket 141 is fixed to the inner side of the rear end cover, and the mounting method can be at least one of screw connection, clamping connection, bonding, etc. The mounting bracket 141 is used to load and fix the Hall circuit board 142. The Hall sensor 143 is installed on the Hall circuit board 142 and is electrically connected to the Hall circuit board 142. The Hall sensor 143 and the extension 132a of the rotor permanent magnet 132 are opposite to each other along the first direction of the sunshade assembly 100, which can realize real-time and accurate detection of the magnetic pole position of the rotor permanent magnet 132, and eliminate the influence of the winding current on the Hall sensor 143.

[0064] Please continue reading Figure 1 In addition, based on any of the above embodiments, the reducer 20 includes a reduction housing 21 and a primary reduction mechanism 22, and the reduction housing 21 is connected to the motor housing 11. For example, the reduction housing 21 is detachably connected to the motor housing 11 through a first fastener 50. The first fastener 50 can be, but is not limited to, any one of a threaded component, an adhesive component, a clamping component, and the like.

[0065] The primary reduction mechanism 22 is rotatably disposed in the reduction housing 21 , and includes a first input end and a first output end that are relatively disposed, the first input end is transmission-connected to the motor shaft 15 , and the first output end is transmission-connected to the transmission member 30 and the reel mechanism 40 .

[0066] During operation, the rotational power output by the driving motor is transmitted to the primary reduction mechanism 22. After being reduced in speed and increased in torque by the primary reduction mechanism 22, it is output to the transmission member 30 and the winding mechanism 40 through the motor shaft 15, driving the transmission member 30 and the winding mechanism 40 to rotate synchronously, thereby driving the curtain to unfold to cover the glass, or driving the curtain to retract to expose the glass.

[0067] Please continue reading Figure 1 and Figure 2 Specifically, the primary reduction mechanism 22 in the above embodiment includes a primary sun gear 221, a primary planetary gear 222 and a primary output frame 223. The primary sun gear 221 is arranged at the end of the motor output shaft, and the primary sun gear 221 is drivingly connected to the primary planetary gear 222. The primary output frame 223 is drivingly connected to the primary planetary gear 222. An inner gear ring 21a is arranged on the inner wall of the reduction housing 21, and the inner gear ring 21a is meshed with the primary planetary gear 222. Therefore, the primary reduction mechanism 22 has a simple structure, stable and efficient power transmission, can effectively reduce speed and increase torque, and improve the effectiveness of curtain driving.

[0068] Furthermore, the reducer 20 further includes a secondary reduction mechanism 23, which includes a second input end and a second output end which are arranged opposite to each other, the second input end is rotatably arranged in the reduction housing 21 and is transmission-connected to the primary output frame 223, and the second output end is transmission-connected to the transmission member 30 and the reel mechanism 40. During operation, the power output by the primary reduction mechanism 22 is transmitted to the secondary reduction mechanism 23, which reduces the speed of the power again and increases the torque, and then outputs it to the transmission member 30 and the reel mechanism 40, further improving the driving efficiency of the curtain cloth, and the secondary reduction mechanism 23 has a simple structure, stable power transmission and high efficiency.

[0069] Specifically, in the above embodiment, the secondary reduction mechanism 23 includes a secondary sun gear 231, a secondary planetary gear 232 and a secondary output frame 233. The secondary sun gear 231 is arranged on the primary output frame 223, and the secondary sun gear 231 is transmission connected to the secondary planetary gear 232, the secondary planetary gear 232 is meshed with the inner gear ring 21a, the secondary output frame 233 is transmission connected to the secondary planetary gear 232, and the end of the secondary output frame 233 extending out of the reduction housing 21 is transmission connected to the transmission member 30 and the reel mechanism 40. When working, the primary output frame 223 drives the secondary sun gear 231 to rotate, and the secondary sun gear 231 then drives the secondary planetary gear 232 to rotate, and the secondary planetary gear 232 rotates synchronously around the secondary sun gear 231, and finally drives the secondary output frame 233 to rotate to output the reduction torque to the transmission member 30 and the reel mechanism 40.

[0070] For example, the end of the secondary output frame 233 extending out of the reduction housing 21 is connected to the transmission member 30 and the reel mechanism 40 through the second fastener 60. Optionally, the second fastener 60 can be any one of a threaded component, an adhesive component, a clamping component, etc., which can be flexibly selected according to actual needs.

[0071] Taking into account that the transmission member 30 will rotate relative to the reduction housing 21, in order to reduce the friction resistance and wear generated between the transmission member 30 and the reduction housing 21, in an optional embodiment, the sunshade assembly 100 also includes a first support member 70, and the first support member 70 is arranged between the outer wall of the reduction housing 21 and the side wall of the receiving groove 31.

[0072] For example, the first support member 70 may be specifically, but not limited to, a bearing. The bearing may be any mature type of bearing product in the prior art and is not specifically limited here.

[0073] Please continue reading Figure 1 In addition, in one embodiment, the roller mechanism 40 includes a roller shutter cylinder 41, a synchronous inner shaft 42 and a pre-tightening connector 43. The synchronous inner shaft 42 is passed through the roller shutter cylinder 41, and the synchronous inner shaft 42 is connected and fixed to the reducer 20 and the transmission member 30. The pre-tightening connector 43 is connected between the roller shutter cylinder 41 and the synchronous inner shaft 42.

[0074] During operation, the power output by the secondary output frame 233 directly drives the synchronous inner shaft 42 to rotate, and the synchronous inner shaft 42 then synchronously drives the rolling roller 41 to rotate through the pre-tightening connector 43. For example, when the rolling roller 41 rotates in a clockwise direction, a retracting effect is formed on the curtain cloth, so that the unfolded curtain cloth can be recovered; when the rolling roller 41 rotates in a counterclockwise direction, a releasing effect is formed on the curtain cloth, so that the retracted curtain cloth can be extended and unfolded.

[0075] In the present application, the transmission member 30 includes a synchronous wheel, the outer part of which is sheathed with a synchronous belt meshing with the synchronous wheel, the synchronous belt is connected with a slider, the slider is connected and fixed to the side of the curtain away from the curtain roller 41, and the curtain roller 41 is wound and installed with the other side of the curtain. Specifically, a pull rod is connected to the side of the curtain away from the roller 41, the slider is connected to the pull rod, and the pull rod and the curtain roller 41 are respectively connected to the opposite sides of the curtain along the extension direction.

[0076] In this way, since the transmission member 30 and the shutter roller 41 rotate synchronously, for example, when both rotate counterclockwise, on the one hand, the shutter roller 41 releases the rolled-up curtain, and at the same time, the synchronous belt drives the slider to pull the other side of the curtain away from the shutter roller 41, so that the curtain can be stretched and unfolded to cover the glass; on the contrary, the shutter roller 41 rolls up the curtain, and at the same time, the slider drives the other side of the curtain to move closer to the shutter roller 41, so that the curtain can be rolled up smoothly and orderly.

[0077] During this process, the pre-tightening connector 43 always applies a pre-tightening force to the shutter roller 41, so that the shutter roller 41 has enough force to tighten the curtain cloth, thereby ensuring that the curtain cloth can always remain in a taut state, so that the sunshade assembly 100 can work normally.

[0078] For example, the pre-tightening connector 43 may be, but is not limited to, a pre-tightening spring, a coil spring, etc. Specifically, the pre-tightening connector 43 forms elastic pre-tightening on the rolling curtain cylinder 41, which can ensure that the curtain is flat after being stretched, and has a good glass shielding effect, or ensure that the curtain remains flat without wrinkles during the winding and recycling process.

[0079] It should be noted that the secondary output frame 233 is connected to the transmission member 30 and the synchronous inner shaft 42 at the same time, which not only further saves space, but also reduces the number of power equipment settings, so as to realize the synchronous drive of the transmission member 30 and the reel mechanism 40 with a more streamlined transmission connection structure.

[0080] The driving force is first transmitted from the secondary output frame 233 to one end of the synchronous inner shaft 42, and then transmitted to the other axial end of the synchronous inner shaft 42, so as to achieve torque balance at both ends of the rolling shaft mechanism and ensure the synchronization of movement of both sides of the curtain.

[0081] Furthermore, in another embodiment, the roller mechanism 40 further includes a second support member 80, which is disposed between the shutter roller 41 and the synchronous inner shaft 42. On the one hand, the second support member 80 is used to form radial support for the shutter roller 41 and the synchronous inner shaft 42 to ensure the relative position and assembly structure are stable; on the other hand, it can also meet the need for relative sliding between the shutter roller 41 and the synchronous inner shaft 42.

[0082] For example, the second support member 80 may be, but is not limited to, a bearing.

[0083] Please continue reading Figure 1 In addition, based on any of the above embodiments, the sunshade assembly 100 further includes a first support frame 90 , and the first support frame 90 is installed outside the reduction housing 21 .

[0084] The sunshade assembly 100 further includes a second support frame 90 a and a third support member 90 b , and the second support frame 90 a is mounted on the outside of the synchronous inner shaft 42 through the third support member 90 b .

[0085] Since the drive motor and the reducer 20 are arranged on one axial side of the winding shaft mechanism 40, they will be subjected to large lateral forces during operation and may easily cause instability or even structural fatigue damage. Therefore, the first support frame 90 and the second support frame 90a are set up to effectively unload the lateral force of the transmission member 30 and the lateral force of the curtain expansion and contraction, thereby ensuring the safety and reliability of the product structure.

[0086] The third support member 90b is used to form installation positioning and support for the synchronous inner shaft 42 and the second support frame 90a, and to prevent the synchronous inner shaft 42 and the second support frame 90a from directly rotating in contact and causing friction and wear, thereby affecting the rotation smoothness and service life of the reel mechanism 40.

[0087] In addition to the above, the present application further provides a vehicle, which includes a vehicle body and a glass assembly, wherein the glass assembly is mounted on the vehicle body. The glass assembly includes glass and a sunshade assembly 100 as described in any of the above embodiments, wherein the sunshade assembly 100 is mounted in conjunction with the glass, and the sunshade assembly 100 can cover or expose the glass.

[0088] According to actual needs, the glass assembly can be but is not limited to any one of a skylight glass assembly, a windshield glass assembly, a side window glass assembly, a rear windshield glass assembly, etc.

[0089] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
