Description

Technical Field

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

[0002] The sunshade structure of a car windshield typically includes a roller, a linkage mechanism, and a curtain. The curtain is rolled up on the roller, which is usually installed inside a housing in front of the dashboard. The linkage mechanism then pulls the sunshade out to the underside of the car's roof to provide sun shading. However, due to the complexity of the curved surface of the car's glass and limitations in installation technology, the linkage mechanism in related technologies often struggles to conform well to the windshield during deployment, leading to noise or instability issues during operation. Summary of the Invention

[0003] Therefore, it is necessary to provide a sunshade assembly, a glass assembly, and a vehicle to address the issue that the linkage mechanism of the sunshade structure in the relevant technology generally has difficulty fitting well against the windshield when deployed, which leads to noise or instability during the operation of the linkage mechanism.

[0004] On one hand, this application provides a sunshade assembly, the sunshade assembly comprising:

[0005] Base;

[0006] A rotating component, which is rotatably connected to the base and is capable of rotating relative to the base about a first direction;

[0007] A reset member is connected to the rotating member, and the reset member is used to apply a torque about the rotating member in the first direction;

[0008] The power assembly includes an extension assembly, one end of which is connected to the rotating member, and the other end is used to connect to the curtain. The extension assembly is used to extend along a second direction and pull the curtain out of the fabric. When the extension assembly is subjected to an external force and extends away from the second direction, the rotating member can overcome the torque applied by the reset member and rotate around the first direction.

[0009] In one embodiment, the rotating member includes a first rotating end and a second rotating end, the rotating member being rotatably connected to the base via the first rotating end and the second rotating end, and the reset member being configured as a torsion spring, the first rotating end and / or the second rotating end being connected to the base via the torsion spring.

[0010] In one embodiment, the travel of the curtain is configured to be 600mm-750mm, the number of coils of the torsion spring is configured to be 8-10, the torsion spring includes a force-applying arm and a fixed arm, the force-applying arm is connected to the rotating component, the fixed arm is connected to the base, the length of the force-applying arm is configured to be 4mm-5mm, and the length of the fixed arm is configured to be 4mm-5mm.

[0011] In one embodiment, the rotating component includes a guide rail, the extension component is configured as a linkage mechanism, and the power component further includes a slider, a transmission component, and a power source. The slider is slidably connected to the guide rail, and the power source drives the slider to slide along the guide rail through the transmission component. One end of the linkage mechanism is connected to the slider, and the other end is connected to the curtain. When the power source drives the slider to slide, the slider drives the linkage mechanism to extend or retract.

[0012] In one embodiment, the linkage mechanism includes a driving rod and a driven rod. One end of the driving rod is connected to the slider, and the other end of the driving rod is connected to the driven rod. The driven rod is connected to the curtain. When the power source drives the slider to slide, the slider drives the driving rod to move. The driving rod pushes or pulls the driven rod to extend or retract the driven rod.

[0013] In one embodiment, the slider includes a sliding portion and a mounting port. The sliding portion is slidably connected to the guide rail, and the mounting port is used to mount the linkage mechanism. The mounting port is configured to face the second direction when the extension component is not subjected to external force.

[0014] In one embodiment, the driven link includes a fixed rod and a driving rod. One end of the fixed rod is rotatably connected to the guide rail, and the other end of the fixed rod is rotatably connected to one end of the driving rod. The other end of the driving rod is connected to the fabric outlet end of the curtain. One end of the driving rod is connected to the slider, and the other end of the driving rod is rotatably connected to the fixed rod.

[0015] In one embodiment, the end of the extension component connected to the curtain is further provided with a connector, the connector being arranged parallel to the first direction.

[0016] In one embodiment, the connector is configured as a rod, and the rod is configured in a shape for engaging with the inner surface of the glass assembly.

[0017] In one embodiment, the end of the extension assembly connected to the curtain is further provided with a buffer, which is used to buffer deformation when the end of the extension assembly is subjected to an external force.

[0018] In one embodiment, the end of the extension component connected to the curtain is further provided with a roller.

[0019] In one embodiment, the end of the extension assembly connected to the curtain is further provided with a connector and a buffer. The connector is configured to fit against the inner surface of the glass assembly. At least two buffers are provided and are evenly arranged along the surface of the connector. The buffers are used to buffer deformation when the end of the extension assembly is subjected to an external force.

[0020] In one embodiment, the base includes a first mounting seat and a second mounting seat spaced apart, and the sunshade assembly also includes a roller, which is parallel to the rotating member and rotatably connected to the first mounting seat and the second mounting seat respectively, and the curtain is wound around the roller.

[0021] On the other hand, this application provides a glass assembly including the sunshade assembly as described above, the glass assembly including a glass component, the glass component being spaced apart from the sunshade assembly, and the second direction being arranged intersecting the inner surface of the glass component.

[0022] In another aspect, this application provides a vehicle including the glass assembly as described above.

[0023] In one embodiment, the vehicle has a dashboard, and the sunshade assembly is detachably mounted in front of the dashboard.

[0024] The aforementioned sunshade assembly, glass assembly, and vehicle, with the rotating component connected to the reset component, help adjust the angle of the rotating component relative to the base around the first direction when the extension assembly is subjected to external force. In other words, when the extension assembly moves to abut against the inner surface of the glass assembly and continues to slide along the inner surface of the glass assembly, the rotating component will continuously be subjected to the reaction force of the glass assembly. Thus, the rotating component can overcome the torque applied by the reset component and rotate relative to the base around the first direction, so that the extension assembly deviates from the second direction and continues to extend. This can improve the fit between the extension assembly and the inner surface of the glass assembly, thereby enhancing the stability of the extension assembly during operation and reducing noise.

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.

[0034] 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.

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.

[0038] Considering that existing sunshade structures are limited by the complexity of vehicle glass surfaces and installation processes, they generally cannot fit well against the windshield when unfolded, which leads to noise or instability problems during the operation of the linkage mechanism. This application provides a sunshade assembly 11, a glass assembly 10, and a vehicle, which can improve the fit between the extension component 510 and the surface of the glass assembly 12 during unfolding and retraction, solve the noise or instability problems of the extension component 510 during operation, and facilitate application and promotion.

[0039] For details, please refer to the appendix. Figures 1 to 2 One embodiment of this application provides a sunshade assembly 11, which may include a base 200, a rotating member 300, a resetting member 400, and a power assembly 500. The rotating member 300 is rotatably connected to the base 200 and can rotate relative to the base 200 about a first direction X1. The resetting member 400 is connected to the rotating member 300 and is used to apply a torque about the first direction X1 to the rotating member 300. The power assembly 500 includes an extension assembly 510, one end of which is connected to the rotating member 300, and the other end is used to connect to the curtain fabric 100. The extension assembly 510 is used to extend along a second direction X2 and pull the curtain fabric 100 out of the fabric. When the extension assembly 510 is subjected to an external force and extends away from the second direction X2, the rotating member 300 can overcome the torque applied by the resetting member 400 and rotate about the first direction X1.

[0040] It should be noted that the aforementioned first direction X1 can be the extension direction of the rotation axis of the rotating member 300 in its length direction.

[0041] According to another aspect of this application, this application also provides a glass assembly 10, which includes the sunshade assembly 11 as described above. The glass assembly 10 includes a glass component 12, which is spaced apart from the sunshade assembly 11, and is arranged in a second direction X2 intersecting with the inner surface of the glass component 12.

[0042] It should be noted that when the glass assembly 12 is installed in the vehicle, it has an inclined direction that extends along its length and forms a certain angle with the horizontal plane. The aforementioned second direction X2 intersects with the inner surface of the glass assembly 12, which means that the second direction X2 is not parallel to the aforementioned inclined direction of the glass assembly 12. Thus, when the extension assembly 510 starts to extend from the folded state along the second direction X2, it will come into contact with the inner surface of the glass assembly 12 and be subjected to force after running a certain distance.

[0043] Therefore, the arrangement of the sunshade assembly 11 and the glass assembly 10, which connects the rotating member 300 to the reset member 400, helps to adjust the angle of the rotating member 300 relative to the base 200 around the first direction X1 when the extension assembly 510 is subjected to external force. In other words, when the extension assembly 510 runs to abut against the inner surface of the glass assembly 12 and continues to slide along the inner surface of the glass assembly 12, the rotating member 300 will be continuously subjected to the reaction force of the glass assembly 12. In this way, the rotating member 300 can overcome the torque applied by the reset member 400 and rotate relative to the base 200 around the first direction X1, so that the extension assembly 510 deviates from the second direction X2 and continues to extend. This can improve the fit between the extension assembly 510 and the inner surface of the glass assembly 12, thereby enhancing the stability of the extension assembly 510 during operation and reducing noise.

[0044] More specifically, when the extension component 510 extends along the second direction X2, since the second direction X2 intersects with the inner surface of the glass component 12, i.e., there is a certain angle between the second direction X2 and the inner surface of the glass component 12, the glass component 12 will exert a reaction force on the extension component 510 when the extension component 510 slides relative to the inner surface of the glass component 12. Thus, the arrangement of the sunshade assembly 11, which connects the rotating component 300 to the reset component 400, helps to apply the aforementioned reaction force to the reset component 400. This allows the reset component 400 to continuously adjust the angle of the rotating component 300 relative to the base 200 around the first direction X1, thereby gradually reducing the angle between the extension plane of the extension component 510 and the glass component 12. This results in the extension plane of the curtain 100 becoming increasingly closer to the inner surface of the glass component 12, thus enhancing the stability of the extension component 510 during operation and reducing noise.

[0045] It is worth noting that the arrangement of the sunshade assembly 11, which connects to the rotating component 300 via the reset component 400, allows the user to adjust the torque applied by the reset component 400 to the rotating component 300 according to actual installation needs. This allows adjustment of the initial angle of the rotating component 300 relative to the base 200 around the first direction X1, thereby adjusting the fabric exit direction of the curtain 100 to meet installation process requirements, such as meeting space layout requirements or preventing interference between the curtain 100 and other vehicle structures during fabric exit. Understandably, since the reset component 400 adjusts the extension direction of the extension component 510 when it abuts against and slides relative to the glass component 12, the user can adjust the fabric exit direction of the curtain 100 (i.e., the second direction X2) within a certain range when the extension component 510 is in a folded state, thereby meeting the aforementioned installation process requirements, such as space utilization requirements or interference avoidance requirements.

[0046] Understandably, during the continuous retraction of the curtain 100, i.e., the folding and retraction of the extension component 510, when the extension component 510 detaches from the glass component 12 and the external force disappears, the rotating component 300 can return to its initial angle under the force of the reset component 400. Subsequently, both the extension component 510 and the curtain 100 can be retracted onto the rotating component 300 to meet the installation process requirements. The structure is simple and reliable.

[0047] Optionally, the aforementioned reset element 400 may be implemented as, but is not limited to, a torsion spring 410, etc.

[0048] Continue reading Figure 2 In one embodiment, the rotating member 300 may include a first rotating end 310 and a second rotating end (not shown), and the rotating member 300 is rotatably connected to the base 200 through the first rotating end 310 and the second rotating end. The reset member 400 is configured as a torsion spring 410, and the first rotating end 310 and / or the second rotating end is connected to the base 200 through the torsion spring 410. Thus, when the rotating member 300 rotates relative to the base 200, the torsion spring 410 can undergo torsional deformation and store energy under the drive of the rotating member 300.

[0049] Understandably, the torsion spring 410 with energy storage can drive the rotating member 300 to return to the initial angle relative to the base 200 when the extension component 510 is retracted, folded and detached from the inner surface of the glass component 12, and at the same time drive the extension component 510 to return to the second direction X2 for retraction and folding, thus meeting the aforementioned installation process requirements.

[0050] It should be noted that the second rotating end is the other end of the rotating member 300. Understandably, the structure of the second rotating end can be the same as that of the first rotating end 310. Therefore, the specific structural diagram of the second rotating end is not shown in this application.

[0051] Optionally, the first rotating end 310 may include a first rotating shaft 311, the second rotating end may include a second rotating shaft, and the base 200 may include a bearing (not shown). The first rotating shaft 311 and the second rotating shaft can be rotatably connected to the base 200 through the aforementioned bearing to ensure the smooth rotation of the rotating component 300, reduce rotational resistance, thereby helping to reduce the deformation required for the torsion spring 410 to overcome rotational resistance and improving the durability of the torsion spring 410.

[0052] Optionally, the travel of the curtain 100 can be configured to be 600mm-750mm, and the number of coils of the torsion spring 410 can be configured to be 8-10 coils. Please refer to [link / reference]. Figure 5The torsion spring 410 includes a force-applying arm 411 and a fixed arm 412. The force-applying arm 411 is connected to the rotating component 300, and the fixed arm 412 is connected to the base 200. The length L1 of the force-applying arm 411 can be configured to be 4mm-5mm, and the length L2 of the fixed arm 412 can be configured to be 4mm-5mm. Thus, under different working conditions, users can adapt different torsion spring 410 specifications according to the movement stroke specifications of the curtain 100 to ensure that the deformation of the torsion spring 410 is sufficient to withstand the operating load of the curtain 100, thereby improving the applicability of the sunshade assembly 11.

[0053] For example, the operating form of the curtain 100 can be configured, but is not limited to, 600mm, 620mm, 650mm, 670mm, 700mm, 720mm or 750mm, which can improve the applicability of the sunshade assembly 11 in different vehicle use scenarios.

[0054] For example, the number of coils of the torsion spring 410 can be configured, but is not limited to, 8, 9, or 10 coils.

[0055] For example, the length L2 of the fixed arm 412 can be configured as 4mm, 4.5mm or 5mm, etc.

[0056] For example, the length L1 of the lever arm 411 can be configured, but is not limited to, 4mm, 4.5mm or 5mm, etc.

[0057] Optionally, the extension component 510 may be implemented as a telescopic rod assembly or a connecting rod assembly, etc. Understandably, as long as the extension component 510 is configured to pull the curtain 100 to extend in the second direction X2, it falls within the protection scope of this application.

[0058] Optionally, in some embodiments, please refer to Figure 3 The rotating component 300 may include a guide rail 320, the extension component 510 may be configured as a linkage mechanism 511, and the power component 500 may also include a slider 520, a transmission component (not shown) and a power source 530. The slider 520 is slidably connected to the guide rail 320, and the power source 530 drives the slider 520 to slide along the guide rail 320 through the transmission component.

[0059] Combination Figure 1 As shown, one end of the linkage mechanism 511 is connected to the slider 520, and the other end is connected to the curtain 100. When the power source 530 drives the slider 520 to slide, the slider 520 drives the linkage mechanism 511 to extend or retract, thus realizing the control of the extension or retraction of the curtain 100 by the linkage mechanism 511. The structure is simple and reliable.

[0060] Optionally, continue to combine Figure 1 and Figure 3As shown, the linkage mechanism 511 may include a driving rod 5111 and a driven link 5112. One end of the driving rod 5111 is connected to the slider 520, and the other end of the driving rod 5111 is connected to the driven link 5112. The driven link 5112 is connected to the curtain 100. When the power source 530 drives the slider 520 to slide, the slider 520 drives the driving rod 5111 to move. Then the driving rod 5111 pushes or pulls the driven link 5112 so that the driven link 5112 extends or retracts, thereby driving the curtain 100 to extend or retract. The structure is simple and reliable.

[0061] Optionally, the aforementioned driven linkage 5112 may also include, but is not limited to, a fixed linkage 5112a and a drive linkage 5112b. One end of the fixed linkage 5112a is rotatably connected to the guide rail 320. It should be noted that this end of the fixed linkage 5112a, while rotatably connected to the guide rail 320, cannot slide relative to the guide rail 320; this end is rotatably connected to a fixed point on the guide rail 320. The other end of the fixed linkage 5112a is rotatably connected to one end of the drive linkage 5112b. The other end of the drive linkage 5112b is connected to the fabric outlet end of the curtain 100. One end of the drive linkage 5111 is connected to the slider 520, and the other end of the drive linkage 5111 is rotatably connected to the fixed linkage 5112a. Thus, when the power source 530 drives the slider 520 to slide, the active rod 5111 can push or pull the fixed rod 5112a to rotate relative to a fixed point on the guide rail 320. Then, the fixed rod 5112a can push or pull the drive rod 5112b to extend or fold, thereby realizing the feeding or retraction of the curtain 100. The structure is simple and reliable.

[0062] Preferably, the other end of the aforementioned active rod 5111 can be rotatably connected to the middle position of the fixed rod 5112a, which helps to improve the stability of the active rod 5111 driving the fixed rod 5112a to rotate.

[0063] It should be noted that, as Figure 3 As shown, the aforementioned linkage mechanism 511 can be configured as two sets, which helps to improve the motion stability of the linkage mechanism 511. In one set, the driving rod 5111 of the linkage mechanism 511 can be connected to a slider 520 on the guide rail 320, and the driving rod 5111 of the other set of linkage mechanisms 511 can be connected to another slider 520. The power source 530 is used to drive the sliders 520 to move towards or away from each other, thus enabling the two sets of linkage mechanisms 511 to extend or retract simultaneously.

[0064] Optionally, the angular velocity of the aforementioned fixed rod 5112a can be configured, but is not limited to, between 16 deg / s and 20 deg / s. Specifically, the angular velocity of the aforementioned fixed rod 5112a can be configured as 16 deg / s, 17 deg / s, 18 deg / s, 19 deg / s, or 20 deg / s, etc. Understandably, the magnitude of the angular velocity of the aforementioned fixed rod 5112a determines the speed of movement of the extension assembly 510. Therefore, limiting the angular velocity of the fixed rod 5112a within a reasonable range helps to further reduce the motion noise of the extension assembly 510 and improve its motion stability.

[0065] Understandably, by adjusting the angular velocity of the fixed rod 5112a, the user only needs to indirectly adjust the sliding speed of the slider 520, and then only needs to indirectly adjust the output power of the power source 530. This helps to improve the ease of adjusting the fabric feeding or retraction speed of the curtain 100.

[0066] Optionally, the aforementioned power source 530 may, but is not limited to, use an electric motor.

[0067] Optionally, according to the above embodiments of this application, the aforementioned transmission component may, but is not limited to, a track or a lead screw. For example, the control method for the aforementioned two sliding members 520 to slide towards or away from each other may, but is not limited to, implementing a continuous cyclical rotation of the track, such as a closed track rotating clockwise or counterclockwise. Alternatively, the track may be rectangular, so that the parallel, spaced-apart tracks on both sides move in opposite directions, thereby connecting the two sliding members 520 respectively. This enables the track to drive the two sliding members 520 towards or away from each other during rotation.

[0068] In other embodiments, the two sliders 520 may also be respectively installed on both sides of the lead screw with opposite threads, and then driven by the lead screw with opposite threads, the two sliders 520 may move closer to or further away from each other.

[0069] Optionally, the slider 520 may include a sliding portion and a mounting port. The sliding portion is slidably connected to the guide rail 320. This sliding portion is not limited to being slidably connected to the guide groove on the guide rail 320 via a snap-fit ​​connection, and is not shown in the figures here. The mounting port is used to mount the linkage mechanism 511. The linkage mechanism 511 can be snapped into the aforementioned mounting port via a snap-fit ​​connection, and is not shown in the figures here. The orientation of the aforementioned mounting port can be configured such that when the extension component 510 is not subjected to external force, the mounting port faces the second direction X2. Thus, when the linkage mechanism 511 is mounted in the mounting port, the extension direction of the linkage mechanism 511 can automatically face the second direction X2, thereby reducing the process of adjusting the extension direction of the linkage mechanism 511 and improving the installation efficiency of the linkage mechanism 511.

[0070] Understandably, the orientation of the aforementioned mounting port can also be finely adjusted by the reset component 400, thus overcoming the installation error that may occur during long-term operation of the mechanism.

[0071] Of course, in some other embodiments, the aforementioned linkage mechanism 511 may also be configured as only one set, which helps to reduce the volume of the overall structure and improve the compactness of the structural layout.

[0072] For example, such as Figure 3 Based on the structure shown, the active rod 5111 can be rotatably connected to the middle of the drive rod 5112b, and the active rod 5111 extends from this middle position to the same length as the drive rod 5112b. The fabric outlet end of the curtain 100 can be directly connected to the ends of the active rod 5111 and the drive rod 5112b away from the guide rail 320. Understandably, in this embodiment, the drive rod 5112b can be omitted. When the power source 530 drives the slider 520 to slide, the active rod 5111 and the drive rod 5112b can extend and fold through the central rotation node.

[0073] Of course, in other embodiments, the aforementioned linkage mechanism 511 may also be configured as 3, 4, or 5 groups, or more. It should be noted that the number of groups of the linkage mechanism 511, the number of rods in each group, the combination method, and the connection relationship between the rods can all be designed according to actual needs. Understandably, as long as the extension and folding of the linkage mechanism 511 can be realized, thereby realizing the fabric 100 being extended or retracted, it is acceptable, and no limitation is made here.

[0074] Optionally, please combine Figure 1 , Figure 3 and Figure 4 As shown, the end of the extension assembly 510 connected to the curtain 100 may also be provided with a connector 540, and the connector 540 is arranged along the first direction X1. This helps to ensure that the connector 540 and the glass assembly 12 have sufficient fitting length and improve the operational stability of the extension assembly 510.

[0075] Alternatively, the aforementioned connector 540 may be implemented as a rod or plate, etc.

[0076] Optionally, the connector 540 is configured to fit against the inner surface of the glass assembly 12, thereby improving the fit between the extension assembly 510 and the glass assembly 12 and reducing stress concentration between the extension assembly 510 and the inner surface of the glass assembly 12, thus protecting the glass assembly 12.

[0077] Optionally, in some embodiments, please refer to Figure 3The connector 540 can be configured as a rod arranged parallel to the first direction X1, and the rod is configured to be curved to fit against the inner surface of the vehicle glass assembly 12. Specifically, compared with other plates or blocks, the rod can reduce the contact width with the glass assembly 12 along the second direction X2, which helps to reduce the friction between the connector 540 and the inner surface of the glass assembly 12 and improve the smoothness of sliding between the connector 540 and the glass assembly. On the other hand, when the connector 540 contacts the inner surface of the glass assembly 12 and slides relative to it, the reaction force of the glass assembly 12 acting on the connector 540 and the action of the reset member 400 will drive the extension assembly 510 to rotate or swing relative to the inner surface of the glass assembly 12 with the connector 540 as the pivot point, so as to adjust the angle between the extension assembly 510 and the glass assembly 12. During the aforementioned swinging process, the connector 540 is configured as a rod with a smaller contact area with the inner surface of the glass assembly 12. This helps to improve the smoothness of the rotation of the extension assembly 510 relative to the inner surface of the glass assembly 12 with the connector 540 as the pivot point, thereby reducing the noise of the extension assembly 510 during operation and improving the operational stability.

[0078] Optionally, please refer to Figure 4 The end of the extension component 510 connected to the curtain 100 may also be provided with a buffer 550. The buffer 550 is used to buffer the deformation when the end of the extension component 510 is subjected to external force, thereby further improving the protection of the glass component 12.

[0079] Alternatively, please continue reading Figure 4 The end of the extension component 510 connected to the curtain 100 may also be provided with a roller 560, which is used to slide on the inner surface of the glass component 12, thereby helping to further improve the smoothness of sliding between the extension component 510 and the glass component 12.

[0080] Optionally, the aforementioned roller 560 may be implemented as a wheel, but is not limited to.

[0081] Preferably, please refer to the following: Figure 3In some embodiments, the end of the extension component 510 connected to the curtain 100 is provided with a connector 540 and a buffer 550. The connector 540 is configured to fit against the inner surface of the glass component 12. At least two buffers 550 are provided and are evenly arranged along the surface of the connector 540. The buffers 550 are used to buffer deformation when the end of the extension component 510 is subjected to external force. It should be noted that in this embodiment, the connector 540 may be implemented as a rod or a long plate, and the buffer 550 is integrated on the connector 540. The connector 540 can indirectly press against the inner surface of the glass assembly 12 through the buffer 550. The buffer 550 can prevent the connector 540 from directly colliding with the inner surface of the glass assembly 12, thereby improving the protection of the glass assembly 12. On the other hand, it can also prevent the connector 540 from directly contacting the inner surface of the glass assembly 12, providing buffer protection for the connector 540, thereby improving the durability of the connector 540.

[0082] Understandably, since the buffer 550 is uniformly arranged along the surface of the connector 540, the buffer 550 can form multiple points of support with the inner surface of the glass assembly 12 along the first direction X1. Thus, the multiple points of support formed between the buffer 550 and the inner surface of the glass assembly 12 can also improve the fit between the extension assembly 510 and the inner surface shape of the glass assembly 12, thereby ensuring the fit between the extension assembly 510 and the glass assembly 12, reducing operating noise and improving operating stability.

[0083] Optionally, according to the above embodiments of this application, the aforementioned roller 560 and buffer 550 can be integrated into one unit and evenly arranged in the extending direction of the connector 540.

[0084] Alternatively, please refer to the following: Figure 2 The base 200 may include a first mounting seat 210 and a second mounting seat 220 spaced apart. The sunshade assembly 11 also includes a roller 101, with the curtain 100 wound around the roller 101. The roller 101 and the rotating member 300 are parallel to each other and rotatably connected to the first mounting seat 210 and the second mounting seat 220 respectively. This helps to improve the structural compactness of the sunshade assembly 11, facilitates structural layout, and improves space utilization.

[0085] According to another aspect of this application, this application also provides a vehicle that may include the glass assembly 10 as described above.

[0086] Optionally, the vehicle may have a dashboard (not shown), and the sunshade assembly 11 can be detachably mounted in front of the dashboard. In other words, the sunshade assembly 11 of this application can be installed on the vehicle in a retrofit configuration. Compared to the design that requires custom sliding rails on the body, such as the sheet metal A-pillar, to achieve the opening and closing of the curtain 100, the sunshade assembly 11 of this application can reduce manufacturing costs, facilitate portability, application, and promotion, and also help improve applicability to different vehicle models. Understandably, for different vehicle models, users only need to adjust the torque of the reset member 400 on the rotating member 300 to adjust the fabric output direction of the sunshade assembly. Therefore, the setting of the reset member 400 allows the sunshade assembly 11 to be installed on different vehicle models in a detachable manner.

[0087] 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.

[0088] 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.
