[0034] 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.

[0035] Please see Figure 1 , Figure 2 and Figure 3This application provides a sunshade assembly 10 in one embodiment, which may include a first wheel assembly 100 and a first curtain assembly 200. The first wheel assembly 100 may include a first synchronous belt 110, a first synchronous pulley 120, and a second synchronous pulley 130, with the first synchronous belt 110 sleeved on the first synchronous pulley 120 and the second synchronous pulley 130. Understandably, the first synchronous pulley 120 and the second synchronous pulley 130 are connected to opposite ends of the first synchronous belt 110. The first curtain assembly 200 is connected to the first synchronous belt 110.

[0036] Please continue reading. Figure 1 and Figure 2 The sunshade assembly 10 also includes a second pulley group 300 and a second curtain group 400. The second pulley group 300 includes a second synchronous belt 310, a third synchronous pulley 320, and a fourth synchronous pulley 330. The second synchronous belt 310 is fitted onto the third synchronous pulley 320 and the fourth synchronous pulley 330. Understandably, the third synchronous pulley 320 and the fourth synchronous pulley 330 are connected to opposite ends of the second synchronous belt 310. The second curtain group 400 is connected to the second synchronous belt 310.

[0037] Combined Figure 2 and Figure 4 As shown, the first synchronous wheel 120 and the third synchronous wheel 320 of the sunshade assembly 10 described above are coaxially arranged, and the first synchronous wheel 120 has a first radius and the third synchronous wheel 320 has a second radius. The first synchronous wheel 120 and the third synchronous wheel 320 are used to rotate coaxially to drive the first curtain group 200 to perform synchronous opening or closing movements at a first speed and the second curtain group 400 to perform synchronous opening or closing movements at a second speed, respectively.

[0038] It should be noted that the first curtain assembly 200 may include a first curtain body and a first roller mechanism 210. The second curtain assembly may include a second curtain body and a second roller mechanism 410. To more clearly illustrate the structural connection relationship of the sunshade assembly 10 of this application, the structural diagrams of the first curtain body of the first curtain assembly 200 and the second curtain body of the second curtain assembly 400 are omitted. Figure 1 As shown, the first curtain can be rolled up on the first roller mechanism 210 of the first curtain group 200. The second curtain can be rolled up on the second roller mechanism 410 of the second curtain group 400.

[0039] Understandably, the simultaneous opening or closing of the first curtain group 200 at a first speed and the simultaneous opening or closing of the second curtain group 400 at a second speed, as described above, refers to the simultaneous opening or closing of the first curtain body of the first curtain group 200 at a first speed and the simultaneous opening or closing of the second curtain body of the second curtain group 400 at a second speed.

[0040] The fabric outlet of the first curtain is connected to the first synchronous belt 110, and the fabric outlet of the second curtain is connected to the second synchronous belt 310.

[0041] The sunshade assembly 10 described in this application firstly achieves the opening and closing motion effect of the double sunshade curtain by combining the first wheel group 100 with the first curtain group 200 and the second wheel group 300 with the second curtain group 400.

[0042] Understandably, the first wheel assembly 100 can serve as the drive component of the first curtain assembly 200. The second wheel assembly 300 can serve as the drive component of the second curtain assembly 400. The aforementioned first curtain assembly 200 and second curtain assembly 400 can be configured as the front and rear sunshade structures of a vehicle, respectively.

[0043] Secondly, the sunshade assembly 10 described above in this application is configured such that the first synchronous wheel 120 and the third synchronous wheel 320 are coaxially arranged and can rotate coaxially, which helps to achieve the effect of synchronous opening and closing of the two sunshade curtains in the sunshade assembly 10.

[0044] Understandably, the arrangement of the first wheel group 100 and the second wheel group 300 in the sunshade assembly 10 of this application enables the arrangement of double sunshades. However, the arrangement of the first wheel group 100 and the second wheel group 300 does not limit whether the first curtain group 200 and the second curtain group 400 move synchronously. Therefore, based on the arrangement structure of the first wheel group 100 and the second wheel group 300, this application arranges the first synchronous wheel 120 and the third synchronous wheel 320 coaxially. This helps to achieve the effect of linkage between the first curtain group 200 and the second curtain group 400, thereby enabling the synchronous opening and closing of the double sunshade curtains in the sunshade assembly 10 of this application.

[0045] Furthermore, the sunshade assembly 10 described above in this application also features a first synchronous pulley 120 with a first radius and a third synchronous pulley 320 with a second radius. This helps to meet the different speed movement requirements of the two sunshades in the sunshade assembly 10, thereby realizing the opening and closing movement functions of the two sunshades in the sunshade assembly 10 at different strokes. Therefore, users can change the ratio of the movement stroke of the first curtain group 200 and the second curtain group 400 according to the design ratio of the first radius to the second radius, thus improving the applicability of the sunshade assembly 10 to different vehicle models.

[0046] The following explains the design principle that "users can change the ratio of the travel distance of the first curtain group 200 to the second curtain group 400 according to the ratio of the first radius to the second radius".

[0047] Understandably, based on the structure where the first synchronous pulley 120 and the third synchronous pulley 320 are coaxially arranged, when the first synchronous pulley 120 and the third synchronous pulley 320 rotate coaxially, the opening and closing movements of the first curtain group 200 and the second curtain group 400 are synchronized. Therefore, the opening and closing movements of the first curtain group 200 and the second curtain group 400 occur at the same time.

[0048] Thus, under the premise that the opening and closing times of the first curtain group 200 and the second curtain group 400 are the same, the ratio of the movement distance of the first curtain group 200 and the second curtain group 400 is the same as the ratio of the first speed to the second speed.

[0049] In other words, the design for the ratio of the travel distance of the first curtain group 200 to the second curtain group 400 only requires designing the ratio of the first speed to the second speed.

[0050] Furthermore, since the first curtain body of the first curtain group 200 is connected to the first synchronous belt 110, and the second curtain body of the second curtain group 400 is connected to the second synchronous belt 310, the first speed at which the first curtain body of the first curtain group 200 moves is equal to the speed at which the first synchronous belt 110 moves, and the second speed at which the second curtain body of the second curtain group 400 moves is equal to the speed at which the second synchronous belt 310 moves.

[0051] In other words, the design for the ratio of the first speed to the second speed only requires designing the ratio of the motion speed of the first synchronous belt 110 to the second synchronous belt 310, which is the ratio of the rotational linear velocity of the first synchronous pulley 120 to the third synchronous pulley 320.

[0052] Furthermore, since the first synchronous pulley 120 and the third synchronous pulley 320 are coaxially arranged, the ratio of the rotational linear velocity of the first synchronous pulley 120 and the third synchronous pulley 320 is equal to the ratio of the radius of the first synchronous pulley 120 and the third synchronous pulley 320.

[0053] In other words, the design of the ratio of the rotational linear velocity of the first synchronous pulley 120 to the third synchronous pulley 320 only requires the design of the ratio of the first radius to the second radius.

[0054] In summary, this application only needs to design the ratio of the first radius to the second radius, which can indirectly design the ratio of the travel distance of the first curtain group 200 and the second curtain group 400. This design process is simple and reliable, and improves the applicability of the sunshade assembly 10 to different vehicle models.

[0055] In some embodiments, the ratio of the second radius to the first radius may be set within a preset range, which may be, but is not limited to, 1.0-2.2. For example, the ratio of the second radius to the first radius may be 1.0, 1.2, 1.4, 1.6, 1.8, 2.0, or 2.2, etc.

[0056] It is worth noting that in this embodiment, when the ratio of the second radius to the first radius is 1.0, it indicates that the first radius and the second radius are equal. In other words, the movement strokes of the first curtain group 200 and the second curtain group 400 are equal. Therefore, the sunshade curtain described above in this application may also include embodiments in which the movement strokes of the first curtain group 200 and the second curtain group 400 are equal, which will not be elaborated here.

[0057] It should be noted that the larger the ratio of the second radius to the first radius, the longer the travel distance of the second curtain group 400 is compared to that of the first curtain group 200. This will result in a larger input torque required for the sunshade assembly 10 on one side of the sunshade, and consequently, a larger noise level.

[0058] Therefore, in this embodiment, in order to balance the reasonable ratio of the travel of the double sunshade curtains, the ratio of the second radius to the first radius can be controlled within 1.0-2.2. This helps to meet the requirements of different travel ratios of the first curtain group 200 and the second curtain group 400 while also addressing the noise problem.

[0059] It should also be noted that, according to the above embodiments of this application, the preset range of the ratio of the second radius to the first radius is set to 1.0-2.2. This ensures that the second radius is greater than or equal to the first radius, which also means that the travel distance of the second curtain group 400 is greater than or equal to the travel distance of the first curtain group 200. However, this does not mean that the travel distance of the front sunshade of the vehicle is necessarily greater than or equal to the travel distance of the rear sunshade, or vice versa. In other words, the aforementioned ratio of the second radius to the first radius only reflects the relationship between the travel distances of the front and rear sunshades, and is not limited to the arrangement of the front and rear sunshades of the vehicle. That is to say, users can arrange the travel distance of the front sunshade of the vehicle to be greater than or equal to that of the rear sunshade, or arrange the travel distance of the rear sunshade of the vehicle to be greater than or equal to that of the front sunshade, according to actual needs. This is not limited here.

[0060] Optionally, the aforementioned first synchronous belt 110 can be connected to the first synchronous pulley 120 and the second synchronous pulley 130 by means of gear transmission.

[0061] Optionally, the aforementioned second synchronous belt 310 can be connected to the third synchronous pulley 320 and the fourth synchronous pulley 330 by means of gear transmission.

[0062] According to the above embodiments of this application, the gear transmission method helps to improve the motion reliability of the first synchronous belt 110 and the second synchronous belt 310.

[0063] Please see Figure 1 In some embodiments, the sunshade assembly 10 may include a power source 500, which is used to connect to and drive one of the first synchronous pulley 120, the second synchronous pulley 130, or the fourth synchronous pulley 330 to rotate. Users can position the power source 500 at the corresponding synchronous pulley position according to the layout requirements of the sunshade assembly 10. This helps to improve the flexibility of the spatial layout of the power source 500 on the sunshade assembly 10 and to improve the structural compactness of the sunshade assembly 10.

[0064] Specifically, since the first synchronous pulley 120 and the third synchronous pulley 320 are coaxially arranged, their coaxial rotation enables the linkage between the first synchronous belt 110 and the second synchronous belt 310. Consequently, the first synchronous pulley 120, the second synchronous pulley 130, the third synchronous pulley 320, and the fourth synchronous pulley 330 can also achieve linkage under the constraint of the first synchronous belt 110 and the second synchronous belt 310.

[0065] Thus, according to the above embodiments of this application, when the power source 500 is connected to and driven to rotate one of the first synchronous pulley 120, the second synchronous pulley 130, or the fourth synchronous pulley 330, the linkage effect between the first synchronous belt 110 and the second synchronous belt 310 can be achieved. In this way, the user can set the power source 500 at the position of the corresponding synchronous pulley according to the actual layout requirements, thereby improving the flexibility of the spatial layout of the power source 500 on the sunshade assembly 10 and improving the structural compactness of the sunshade assembly 10.

[0066] Preferably, the power source 500 is used to connect to and drive the first synchronous pulley 120 to rotate. Thus, where the spatial structure allows, the power source 500 can be centrally located, allowing for more direct driving of the first synchronous belt 110 and the second synchronous belt 310 during linkage. Compared to the power source 500 driving the second synchronous pulley 130 or the fourth synchronous pulley 330, this reduces transmission efficiency loss, thereby lowering the energy consumption and resistance of the power source 500.

[0067] Optionally, the aforementioned power source 500 may be, but is not limited to, an electric motor. Specifically, the motor may be, but is not limited to, an L-type motor or a frameless torque motor.

[0068] Please see Figure 1In some embodiments, the sunshade assembly 10 may further include a first frame 600 and a second frame 700, the first frame 600 and the second frame 700 being configured to extend along the same length direction, the first frame 600 having a first window 601, the second frame 700 having a second window 701, the first curtain group 200 being used to open and close the curtain on the first window 601, and the first curtain group 200 being used to open and close the curtain on the second window 701.

[0069] Specifically, the sunshade assembly 10 of this application is configured with the first frame 600 and the second frame 700 extending along the same length direction, which helps to realize the combined arrangement of the first curtain group 200 and the second curtain group 400 on the front and rear sunshades of the vehicle, thus adapting to the design trend of increasingly larger sunroof areas in vehicles.

[0070] In addition, the combination of the first frame 600 and the second frame 700 in this application helps to reduce the volume of a single frame, thereby improving the structural strength of the single frame and thus improving the opening and closing stability of the first curtain group 200 and the second curtain group 400.

[0071] It is worth noting that, in this embodiment, under the premise that the first curtain group 200 and the second curtain group 400 realize the combined arrangement of front and rear sunshades, the coaxially arranged first synchronous wheel 120 and third synchronous wheel 320 must be adaptively arranged at the connection between the first frame 600 and the second frame 700. This can correspondingly realize the extension arrangement of the first synchronous belt 110 along the direction of the first window 601 and the extension arrangement of the second synchronous belt 310 along the direction of the second window 701, thereby realizing the arrangement of the first curtain group 200 and the second curtain group 400 as front and rear sunshades on the vehicle.

[0072] Please see Figure 1 and Figure 2 In some embodiments, the first curtain group 200 may include a first roller mechanism 210, which may be coaxially arranged with the first synchronous pulley 120. The second curtain group 400 includes a second roller mechanism 410, which may be coaxially arranged with the fourth synchronous pulley 330, thereby further realizing the requirement that the first curtain group 200 and the second curtain group 400 open and close in the same direction.

[0073] It should be noted that the aforementioned first roller mechanism 210 is used to roll up the first curtain (not shown). The second roller mechanism 410 is used to roll up the second curtain (not shown). The first roller mechanism 210 is coaxially arranged with the first synchronous pulley 120, that is, the first curtain can be rolled up at the connection between the first frame 600 and the second frame 700, and at the same time, the first curtain can move towards the first window 601 to close the curtain.

[0074] The second roller mechanism 410 is coaxially arranged with the fourth synchronous wheel 330. That is to say, the second curtain is rolled up at the end of the second frame 700 away from the first roller mechanism 210, and at the same time, the second curtain can move towards the second window 701 to close the curtain. This makes the closing direction of the first curtain and the second curtain consistent, thereby meeting the requirement that the first curtain group 200 and the second curtain group 400 open and close the curtain in the same direction.

[0075] In some other embodiments, the first roller mechanism 210 may also be coaxially arranged with the second synchronous wheel 130, and the second roller mechanism 410 may be coaxially arranged with the fourth synchronous wheel 330. This can meet the requirements of closing the first curtain body and the second curtain body in opposite directions and opening the curtain in opposite directions. This improves the arrangement flexibility of the first curtain group 200 and the second curtain group 400. Users can flexibly adjust the arrangement position of the first roller mechanism 210 and the second roller mechanism 410 according to actual needs for the opening and closing of the curtains. There are no restrictions here.

[0076] Please see Figure 1 and Figure 5 In some embodiments, the first frame 600 may include a first guide rail assembly 610 and a first crossbeam mechanism 620, the first crossbeam mechanism 620 being connected to the first guide rail assembly 610 along its width direction. The second frame 700 includes a second guide rail assembly 710 and a second crossbeam mechanism 720, the second crossbeam mechanism 720 being connected to the second guide rail assembly 710 along its width direction.

[0077] It should be noted that the aforementioned first guide rail assembly 610 is used for sliding connection of the first curtain group 200 to realize the opening and closing movement of the curtain. The second guide rail assembly 710 is used for sliding connection of the second curtain group 400 to realize the opening and closing movement of the curtain. In addition, the aforementioned first crossbeam mechanism 620 and second crossbeam mechanism 720 help to improve the overall strength of the first frame 600 and the second frame 700.

[0078] Optionally, please refer to Figure 5 The aforementioned first crossbeam mechanism 620 may include a front crossbeam 621 and a middle crossbeam 622, and the second crossbeam mechanism 720 may be configured as a rear crossbeam. In this way, the front, middle and rear positions can be strengthened in the overall connection between the first frame 600 and the second frame 700, and the structure is simple and reliable.

[0079] Please continue reading. Figure 5In some embodiments, the aforementioned first curtain group 200 may further include a first pull rod mechanism 220, which is used to connect to the fabric outlet end of the first curtain body, and the two ends of the first pull rod mechanism 220 are fixedly connected to the first synchronous belt 110 and slidably connected to the first guide rail assembly 610.

[0080] Optionally, sliders may be provided at both ends of the aforementioned first pull rod mechanism 220.

[0081] Please continue reading. Figure 5 In some embodiments, the aforementioned second curtain assembly 400 further includes a second pull rod mechanism 420, which is used to connect to the fabric outlet end of the second curtain body, and both ends of the second pull rod mechanism 420 are fixedly connected to the second synchronous belt 310 and slidably connected to the second guide rail assembly 710.

[0082] Optionally, sliders may be provided at both ends of the aforementioned second tie rod mechanism 420.

[0083] It should be noted that the first speed of the opening and closing movement of the first curtain body is consistent with the movement speed of the first pull rod mechanism 220. In other words, the first speed of the opening and closing movement of the first curtain body is not affected by the rotation speed of the first roller mechanism 210. Similarly, the second speed of the opening and closing movement of the second curtain body is also not affected by the rotation speed of the second roller mechanism 410. This ensures that the ratio of the first speed to the second speed is designed to be related only to the ratio of the first radius to the second radius.

[0084] Specifically, both the first roller mechanism 210 and the second roller mechanism 410 may be provided with corresponding spring structures (not shown). These spring structures are used to tension the first curtain and the second curtain, thereby eliminating the problem of wrinkles and loosening of the first curtain caused by the inconsistent movement speed between the first pull rod mechanism 220 and the first roller mechanism 210, and eliminating the problem of wrinkles and loosening of the second curtain caused by the inconsistent movement speed between the second pull rod mechanism 420 and the second roller mechanism 410. This ensures the flatness of the first and second curtains in their unfolded and rolled-up states.

[0085] Please see Figure 2 and Figure 5 In some embodiments, the sunshade assembly 10 may further include a first fixing seat 810 for connecting the first frame 600 and the second frame 700, and the first synchronous wheel 120 and the third synchronous wheel 320 are mounted on the first fixing seat 810.

[0086] Specifically, the first fixing seat 810 can serve as a structure for connecting the first frame 600 and the second frame 700, and can also serve as a mounting base for the first synchronous wheel 120 and the third synchronous wheel 320, which helps to improve the compactness of the structural arrangement of the sunshade assembly 10.

[0087] Optionally, the first fixing seat 810 and the first frame 600 may be connected by bolts, welding, or snap-fit, among other things. The first fixing seat 810 and the second frame 700 may be connected by bolts, welding, or snap-fit, among other things.

[0088] Please see Figure 5 In some embodiments, the sunshade assembly 10 may further include a second fixing seat 820 and a third fixing seat 830, wherein the second fixing seat 820 is connected to the end of the first frame 600 away from the first fixing seat 810, and the third fixing seat 830 is connected to the end of the second frame 700 away from the first fixing seat 810. The second fixing seat 820 is used to mount the second synchronous pulley 130, and the third fixing seat 830 is used to mount the fourth synchronous pulley 330, which helps to ensure the installation stability of the second synchronous pulley 130 and the fourth synchronous pulley 330.

[0089] Please combine Figure 2 and Figure 4 As shown, in some embodiments, the first synchronous pulley 120 may be provided with a first limiting part 121 along its circumference. The first radius of the first synchronous pulley 120 is smaller than the second radius of the third synchronous pulley 320. The third synchronous pulley 320 is provided with a sidewall 320a. The first synchronous belt 110 is limited between the first limiting part 121 and the sidewall 320a along the axial direction Y of the first synchronous pulley 120. This helps to prevent the first synchronous belt 110 from loosening along the axial direction Y of the first synchronous belt 110.

[0090] Optionally, the aforementioned first limiting part 121 can be configured as a plurality of stops provided along the circumferential edge of the first synchronous pulley 120, which helps to limit one side of the first synchronous belt 110.

[0091] It is worth noting that, in this embodiment, based on the design of a specific ratio between the first radius of the first synchronous pulley 120 and the second radius of the third synchronous pulley 320, the design of the first radius being smaller than the second radius can be used to make the third synchronous pulley 320 with a larger radius a limiting structure for the first synchronous belt 110. This helps to reduce the additional structural settings for limiting the other side of the first synchronous belt 110 and improves the compactness of the structural layout of the sunshade assembly 10.

[0092] Of course, in some other embodiments, the aforementioned first radius can also be configured to be greater than the second radius, so that the side wall corresponding to the first synchronous pulley 120 can serve as a limiting structure for one side of the second synchronous belt 310.

[0093] Please combine Figure 2 and Figure 4 As shown, in some embodiments, the third synchronous pulley 320 may be provided with a second limiting part 321 along its circumference, and the first fixed seat 810 may be provided with a third limiting part 811. The second synchronous belt 310 is limited between the second limiting part 321 and the third limiting part 811 along the axial direction Y of the third synchronous pulley 320, which helps to prevent the second synchronous belt 310 from loosening along the axial direction Y of the second synchronous belt 310.

[0094] Specifically, the aforementioned second limiting part 321 can be configured as a plurality of stops provided along the circumferential edge of the third synchronous pulley 320, which helps to limit the second synchronous belt 310 on one side of the width direction of the second synchronous belt 310.

[0095] It is worth noting that when the second radius of the third synchronous pulley 320 is configured to be greater than the first radius of the first synchronous pulley 120, the setting of the third limiting part 811 helps to avoid the problem of the second synchronous belt 310 becoming loose due to the lack of limiting on the side of the second synchronous belt 310 facing the first synchronous pulley 120 in the width direction.

[0096] Please continue reading. Figure 2 The third limiting part 811 can also be configured to abut against the outer contour surface of the second synchronous belt 310 along the thickness direction Z of the second synchronous belt 310, which helps to further prevent the second synchronous belt 310 from becoming loose.

[0097] It should be noted that the outer contour surface of the second synchronous belt 310 mentioned above refers to the outer surface of the second synchronous belt 310 on the side away from the third synchronous pulley 320. In this way, the third limiting part 811 and the third synchronous pulley 320 can form abutment and limiting on both sides of the second synchronous belt 310 in the thickness direction Z, which can prevent the second synchronous belt 310 from loosening along the thickness direction Z.

[0098] Please continue reading. Figure 1 , Figure 2 and Figure 5In some embodiments, the sunshade assembly 10 may further include a first tensioning mechanism 140 for pressing against the outer contour surface of the first synchronous belt 110; and / or, the sunshade assembly 10 may further include a second tensioning mechanism 340 for pressing against the outer contour surface of the second synchronous belt 310, which helps to improve the tension of the first synchronous belt 110 and the second synchronous belt 310, thereby improving the transmission stability of the first synchronous belt 110 and the second synchronous belt 310.

[0099] Optionally, the aforementioned first tensioning mechanism 140 can be connected to the first fixed base 810. The second tensioning mechanism 340 can be connected to the third fixed base 830. This helps to improve the compactness of the structural arrangement of the sunshade assembly 10 with the first tensioning mechanism 140 and the second tensioning mechanism 340.

[0100] Optionally, the aforementioned first tensioning mechanism 140 and second tensioning mechanism 340 may be configured, but are not limited to, to achieve tensioning through a spring and a pressure wheel. Optionally, the first radius of the first synchronous wheel 120 may be greater than or equal to 10mm, such as 10mm, 11mm, 12mm, 13mm, 14mm, or 25mm, etc. This helps to meet the requirements of different stroke ratios between the first curtain group 200 and the second curtain group 400, while also preventing the first tensioning mechanism 140 and the second tensioning mechanism 340 from causing the first synchronous belt 110 and the second synchronous belt 310 to experience tooth clipping under spring pressure, thereby improving the tensioning effect of the first tensioning mechanism 140 and the second tensioning mechanism 340.

[0102] Optionally, the glass assembly described above in this application may be configured as a sunroof assembly or side window assembly of a vehicle, etc.
