Description

Technical Field

[0001] This application relates to the technical field of automotive sunshades, and in particular to a sunshade assembly, a glass assembly, and a vehicle. Background Technology

[0002] A car sunshade is an automotive accessory used to block sunlight, designed to protect the vehicle's interior and improve driving comfort. It primarily works by reducing sunlight exposure to the car's interior, extending the lifespan of the interior materials, and preventing sunlight from reaching the cabin, thus improving passenger comfort. A sunshade typically consists of a power unit, a roller shutter shaft, and a fabric curtain. The power unit is connected to the roller shutter shaft and drives its rotation to unfold or retract the fabric curtain.

[0003] Traditional power equipment mostly uses chain reduction gears or screw reduction gears. Both of these methods suffer from problems such as large size, low integration, large installation space occupation, and reduced glass light-transmitting area. Summary of the Invention

[0004] Therefore, it is necessary to provide a sunshade assembly, glass assembly, and vehicle to address the problems of low integration, large size leading to large installation space occupation, and reduced glass light-receiving area.

[0009] A reel mechanism is provided, which is connected to the reducer and is located on the side of the reducer away from the driver. The transmission component is located at the end of the reel mechanism.

[0010] In this sunshade assembly, the driving force output by the driver is reduced in speed and increased in torque by the reducer, and can be simultaneously output to the transmission component and the roller mechanism, enabling the transmission component and the roller mechanism to rotate synchronously, thereby driving the curtain to unfold or retract, realizing the sunshade assembly's sunshade and retraction functions. In this way, the power source consisting of the driver and the reducer is simultaneously connected to the transmission component and the roller mechanism, reducing the number of drivers, simplifying the structure of the sunshade assembly, improving the integration level of the sunshade assembly, and thus helping to reduce the overall size of the sunshade assembly, achieving miniaturization design, reducing the installation space required by the sunshade assembly, and thus reducing the impact on the glass's light-transmitting area.

Detailed Implementation

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0042] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

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

[0048] For example, the sunshade assembly 100 includes a driver 10, a reducer 20, a transmission member 30, and a roller mechanism 40. The reducer 20 is drivenly connected to the driver 10 and to the transmission member 30, which is located on the side of the reducer 20 away from the driver 10. The roller mechanism 40 is drivenly connected to the reducer 20 and is located on the side of the reducer 20 away from the driver 10. The transmission member 30 is disposed at the end of the roller mechanism 40.

[0049] Preferably, the driver 10, reducer 20, transmission component 30, and reel mechanism 40 are coaxially arranged. This arrangement makes the four components neatly and compactly assembled, with a small size and minimal space occupation. It also helps to shorten the power transmission path and improve power output efficiency.

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

[0051] In summary, implementing 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, after being reduced in speed and increased in torque by the reducer 20, can be simultaneously output to the transmission component 30 and the roller mechanism 40, so that the transmission component 30 and the roller mechanism 40 can rotate synchronously, thereby driving the curtains installed with them to unfold or retract, realizing the sunshade function of the sunshade assembly 100; in this way, on the one hand, the power source composed of the driver 10 and the reducer 20 is simultaneously connected to the transmission component 30 and the roller mechanism 40, reducing the driver 10's power output. The reduction in the number of settings simplifies the structural composition of the sunshade assembly 100 and improves its integration level. On the other hand, by setting a receiving groove 31 on the transmission component 30, at least a part of the structure of the reducer 20 can be built into the receiving groove 31 while the reducer 20 is connected to the transmission component 30. This improves the integration level between the reducer 20 and the transmission component 30, thereby helping to reduce the overall volume of the sunshade assembly 100, achieve miniaturization design, reduce the installation space required by the sunshade assembly 100, and thus reduce the impact on the glass light-transmitting area.

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

[0053] In this embodiment, the drive 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 disposed on the motor housing 11 and passes through the interior of the stator assembly 12, and the position detection assembly 14 is disposed on the motor housing 11 and cooperates with the rotor assembly 13.

[0054] The motor housing 11 serves as the main load-bearing component, housing the integrated stator assembly 12, rotor assembly 13, and position detection assembly 14. During operation, energizing the stator assembly 12 generates a rotating magnetic field. This magnetic field interacts with the magnetic field of the rotor assembly 13 to produce torque, causing the rotor assembly 13 to rotate and output rotational driving force to the reducer 20. During this process, the position detection assembly 14 detects the rotor pole position of the rotor assembly 13, improving the accuracy of power output. Furthermore, by detecting the rotor pole position in real time, the motor control system can more accurately control the operating state of the drive motor, thereby improving the control precision. Moreover, precise rotor pole position detection helps ensure the drive motor operates in optimal condition, reducing energy loss and improving operating efficiency. Finally, through real-time monitoring and feedback, abnormal conditions during drive motor operation can be detected promptly, allowing for timely intervention 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 near the reducer 20 extends to the outside of the motor housing 11 and is connected to the reducer 20 for transmission. When the rotor assembly 13 rotates under the action of magnetic field torque, the rotational power can be transmitted to the reducer 20 through the motor shaft 15, thereby outputting 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 disposed outside the stator core 121, and the rotor assembly 13 includes a rotor core 131 and a rotor permanent magnet 132 disposed outside the rotor core 131. The rotor permanent magnet 132 is configured in conjunction with the position detection assembly 14.

[0057] The stator core 121 is used to mount and fix the stator winding 122. For example, the stator core 121 has a toothed structure on its outer periphery, and the stator winding 122 is wound in this toothed structure. The installation method is simple, the stability is good, and a large number of turns of stator winding 122 can be installed, which helps to strengthen 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 outside the rotor core 131 can also generate a magnetic field. This magnetic field 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 via the mounting bracket 141, and the Hall sensor 143 is disposed on the Hall circuit board 142.

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

[0060] The first direction is specifically as follows: Figure 2 The direction of the middle arrow S.

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

[0062] In this application, the motor housing 11 is specifically composed of a front cover, a rear cover, and an annular housing body. The front cover and the rear cover are respectively sealed and installed at the two axial open ends of the housing body. The installation method can be at least one of screwing, welding, riveting, or bonding. Furthermore, a mounting hole is provided in the middle of both the front cover and the rear cover, and a bearing is installed in the mounting hole. The bearing is used to rotatably assemble with the end shaft of the rotor assembly 13.

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

[0064] Please continue reading. Figure 1 Furthermore, based on any of the above embodiments, the reducer 20 includes a reduction housing 21 and a first-stage reduction mechanism 22, with the reduction housing 21 connected to the motor housing 11. For example, the reduction housing 21 is detachably connected to the motor housing 11 via a first fastener 50. The first fastener 50 can be, but is not limited to, any of the following: threaded components, adhesive components, snap-fit ​​components, etc.

[0065] The first-stage reduction mechanism 22 is rotatably disposed within the reduction housing 21. The first-stage reduction mechanism 22 includes a first input end and a first output end disposed opposite to each other. The first input end is connected to the motor shaft 15 for transmission, and the first output end is connected to the transmission component 30 and the reel mechanism 40 for transmission.

[0066] During operation, the rotational power output by the drive motor is transmitted to the first-stage reduction mechanism 22. After the first-stage reduction mechanism 22 reduces the speed and increases the torque, it is then output to the transmission component 30 and the winding mechanism 40 through the motor shaft 15, which drives the transmission component 30 and the winding mechanism 40 to rotate synchronously, thereby enabling the curtain to unfold to cover the glass, or to retract the curtain to expose the glass.

[0067] Please continue reading. Figure 1 and Figure 2 Specifically, in the above embodiment, the primary reduction mechanism 22 includes a primary sun gear 221, a primary planetary gear 222, and a primary output frame 223. The primary sun gear 221 is located at the end of the motor output shaft and is driven by the primary planetary gear 222. The primary output frame 223 is also driven by the primary planetary gear 222. An internal gear ring 21a is provided on the inner wall of the reduction housing 21, and the internal gear ring 21a meshes with the primary planetary gear 222. Therefore, the primary reduction mechanism 22 has a simple structure, smooth power transmission, and high efficiency. It can effectively reduce speed and increase torque, thereby improving the effectiveness of driving the curtain fabric.

[0068] Furthermore, the reducer 20 also includes a secondary reduction mechanism 23. The secondary reduction mechanism 23 includes a second input end and a second output end arranged opposite to each other. The second input end is rotatably disposed within the reduction housing 21 and is drive-connected to the primary output frame 223. The second output end is drive-connected to the transmission component 30 and the winding mechanism 40. During operation, the power output from the primary reduction mechanism 22 is transmitted to the secondary reduction mechanism 23. The secondary reduction mechanism 23 further reduces the speed of the power and increases the torque before outputting it to the transmission component 30 and the winding mechanism 40, further improving the driving efficiency of the curtain. Moreover, the secondary reduction mechanism 23 has a simple structure, smooth 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 disposed on the primary output frame 223, and the secondary sun gear 231 is connected to the secondary planetary gear 232. The secondary planetary gear 232 meshes with the internal gear ring 21a. The secondary output frame 233 is connected to the secondary planetary gear 232, and the end of the secondary output frame 233 extending out of the reduction housing 21 is connected to the transmission component 30 and the winding mechanism 40. When working, the primary output frame 223 drives the secondary sun gear 231 to rotate, and the secondary sun gear 231 drives the secondary planetary gear 232 to rotate. 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 reduction torque to the transmission component 30 and the winding 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 component 30 and the reel mechanism 40 via a second fastener 60. Optionally, the second fastener 60 can be any of the following: threaded component, adhesive component, snap-fit ​​component, etc., which can be flexibly selected according to actual needs.

[0071] Considering that the transmission component 30 will rotate relative to the reduction housing 21, in order to reduce the frictional resistance and wear generated between the transmission component 30 and the reduction housing 21, in an optional embodiment, the sunshade assembly 100 further includes a first support component 70, which is disposed 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 specifically adopt, but is not limited to, a bearing, which may be any mature type of bearing product in the prior art, without specific limitations here.

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

[0074] During operation, the power output from the secondary output frame 233 directly drives the synchronous inner shaft 42 to rotate. The synchronous inner shaft 42 then drives the roller shutter drum 41 to rotate synchronously through the pre-tightening connector 43. For example, when the roller shutter drum 41 rotates clockwise, it creates a rolling effect on the curtain, thereby retracting the unfolded curtain. When the roller shutter drum 41 rotates counterclockwise, it creates a releasing effect on the curtain, thereby extending and unfolding the rolled-up curtain.

[0075] In this application, the transmission component 30 includes a synchronous pulley, and a synchronous belt meshing with the synchronous pulley is fitted around the synchronous pulley. The synchronous belt is connected to a slider, which is fixedly connected to the side of the curtain away from the roller shutter 41. The roller shutter 41 is wound and installed around the other side of the curtain. Specifically, a pull rod is connected to the side of the curtain away from the roller shutter 41, and the slider is drivenly connected to the pull rod. The pull rod and the roller shutter 41 are respectively connected to the opposite sides of the curtain along the extension and retraction direction.

[0076] In this way, since the transmission component 30 and the roller shutter 41 rotate synchronously, for example, when both rotate counterclockwise, the roller shutter 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 roller shutter 41, thereby stretching and unfolding the curtain to cover the glass; conversely, the roller shutter 41 rolls up the curtain, and at the same time, the slider drives the other side of the curtain to move closer to the roller shutter 41, thus achieving a flat and orderly roll-up of the curtain.

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

[0078] For example, the pre-tensioning connector 43 can be, but is not limited to, a pre-tensioning spring, a coil spring, etc. Specifically, the pre-tensioning connector 43 provides elastic pre-tension to the roller shutter cylinder 41, which can ensure that the extended curtain is flat and provides good shading effect on the glass, or ensure that the curtain remains flat and does not wrinkle during the winding and retraction process.

[0079] It should be noted that the secondary output frame 233 connects both the transmission component 30 and the synchronous inner shaft 42, which not only further saves space but also reduces the number of power equipment, thereby achieving synchronous drive of the transmission component 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 to the other end of the synchronous inner shaft 42 in the axial direction, so as to achieve torque balance at both ends of the roller shutter shaft mechanism and ensure the synchronicity of the 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 roller shutter tube 41 and the synchronous inner shaft 42. On the one hand, the second support member 80 is used to provide radial support for the roller shutter tube 41 and the synchronous inner shaft 42, ensuring the stability of their relative positions and assembly structure; on the other hand, it can also meet the need for relative sliding between the roller shutter tube 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 also includes a first support frame 90, which is mounted on the outside of the reduction housing 21.

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

[0085] Since the drive motor and reducer 20 are arranged on one side of the axial direction of the roller mechanism 40, they will be subjected to a large lateral force during operation, which may easily cause instability or even structural fatigue damage. Therefore, the first support frame 90 and the second support frame 90a can effectively relieve the lateral force of the transmission component 30 and the lateral force of the curtain extension and contraction, ensuring the safety and reliability of the product structure.

[0086] The third support member 90b is used to provide 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 and contacting each other, which would cause friction and wear and affect the smoothness of the rotation of the reel mechanism 40 and its service life.

[0087] In addition to the above, this application also provides a vehicle including a body and a glass assembly, the glass assembly being mounted on the vehicle body. The glass assembly includes glass and a sunshade assembly 100 as described in any of the above embodiments, the sunshade assembly 100 being fitted with the glass and capable of covering or exposing the glass.

[0088] Depending on actual needs, the glass assembly can be, but is not limited to, any one of the following: panoramic glass assembly, windshield assembly, side window glass assembly, and rear window glass assembly.

[0089] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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 embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
