Description

Technical Field

[0001] The present application relates to the field of automobile roofs, and in particular to an automatic rolling curtain device for an automobile roof. Background Art

[0002] As people's living standards improve, their expectations for car interiors are also increasing. As an important component of the vehicle's interior, the car roof not only affects the interior's aesthetics but also directly impacts riding comfort. Currently, most car roofs on the market use fixed or manually operated sunshades. While these designs can meet basic needs, they still need to be improved in terms of convenience and automation. In addition, with the development of smart technology, consumers' demand for in-vehicle intelligent devices is growing, which has led to the emergence of more high-tech products and further promoted the research and development and innovation of automatic roller blind technology for car roofs.

[0003] In the related technologies, there are mainly two types of car roof sunshade solutions on the current market: one is a fixed sunshade, which is usually pre-installed in the car by the manufacturer, cannot be adjusted, and is relatively simple to use; the other is a manually operated sunshade, which is opened and closed by a pull rope or other manual mechanism. Although the blocking area can be adjusted, it is inconvenient to operate, especially difficult to operate effectively during driving.

[0004] The above-mentioned related technologies have the following defects: once installed, the fixed sunshade is difficult to modify and cannot adapt to the shading needs under different light conditions. The manually operated sunshade requires manual intervention, which is very inconvenient to use while driving and may even cause safety hazards. Therefore, the two current styles of sunshades cannot be safely adjusted while driving. Utility Model Content

[0005] In order to enable the sunshade to be safely adjusted while driving, the present application provides an automatic rolling curtain device for a car roof.

[0006] The present application provides an automatic rolling curtain device for a car roof that adopts the following technical solutions:

[0007] An automatic rolling curtain device for a car roof comprises a frame, a drive assembly and two rolling curtain assemblies, wherein the rolling curtain assemblies are mounted on the frame, and the two rolling curtain assemblies are symmetrically arranged in the width direction of the frame; the rolling curtain assembly comprises a reel and a pull rod, wherein the reel and the pull rod are both arranged along the length direction of the frame, and the reel and the pull rod are spaced apart in the width direction of the frame; the end of the reel is rotatably connected to the frame, and the end of the pull rod is slidably connected to the frame in the width direction of the frame, and a curtain is connected between the pull rod and the reel; the drive assembly is mounted on the frame, and is used to drive the pull rod to slide on the frame.

[0008] By adopting this technical solution, the frame serves as the foundational structure of the entire device, ensuring stable installation and operation of all components and improving the reliability and durability of the entire device. The drive assembly precisely controls the sliding of the pull rod, which rotates the reel in conjunction with the sliding of the pull rod, allowing the curtain to be smoothly deployed and retracted. This achieves automated opening and closing of the roller blind, eliminating the inconvenience of manual operation and significantly improving ease of use and safety, especially during driving.

[0009] Preferably, the frame includes a long mounting plate and two side mounting brackets, and in the length direction of the long mounting plate, the two side mounting brackets are respectively arranged at both ends of the long mounting plate; the two rolling curtain assemblies are respectively arranged on both sides of the width direction of the long mounting plate, and are both located between the two side mounting brackets, and are both connected to the side mounting brackets; the reel and the pull rod are both arranged along the length direction of the long mounting plate, and the pull rod is located between the reel and the long mounting plate; the two ends of the reel are rotatably connected to the two side mounting brackets, and in the width direction of the long mounting plate, the two ends of the pull rod are respectively slidably connected to the two side mounting brackets.

[0010] By adopting this technical solution, the frame structure design enables the roller blind assembly to be stably mounted on the vehicle roof. The long mounting plate and side mounting brackets ensure symmetrical widthwise placement of the roller blind assembly. The arrangement of the reel and pull rod allows for smooth deployment and retraction of the curtain on the frame, while the rotating connection of the reel and the sliding connection of the pull rod ensure smooth movement of the roller blind assembly. This design not only improves operational convenience but also enhances system reliability and stability.

[0011] Preferably, the rolling shutter assembly also includes a first side slide rail and a second side slide rail, the first side slide rail and the second side slide rail are both arranged along the width direction of the long mounting plate, and are respectively located on both sides of the pull rod, and are both connected to the side mounting bracket; the two ends of the pull rod are respectively provided with a first side slider and a second side slider, the first side slider is slidably connected to the first side slide rail, and the second side slider is slidably connected to the first side slide rail.

[0012] By adopting this technical solution, the provision of the first and second side rails ensures that the pull rod has good guidance during sliding, preventing it from drifting or getting stuck during movement, and improving the operational stability of the rolling shutter assembly. Furthermore, the sliding connection between the first and second side sliders and their corresponding rails allows the pull rod to move more smoothly within the frame, enhancing the operational convenience and reliability of the rolling shutter assembly. Furthermore, this structural design helps extend the service life of the rolling shutter assembly and reduce wear caused by friction.

This ensures consistency and stability on both sides of the roller blinds, preventing uneven force on one side that could cause the roller blinds to jam or become damaged. Furthermore, this design simplifies the drive mechanism, improving system reliability and durability while reducing maintenance costs.

[0015] Preferably, a guide tube is sleeved on the pull rope, and the guide tube is arranged between the two side mounting brackets and connected to the long mounting plate.

[0016] By adopting this technical solution, the draw cord is effectively guided and positioned, ensuring it does not deflect or become tangled during movement, thereby improving the stability and reliability of the roller blind. Specifically, the guide tube allows the draw cord to slide smoothly between the two side mounting brackets, preventing uneven deployment or jamming of the roller blind caused by loose or stuck draw cords, thereby improving user experience and safety.

[0017] Preferably, a torsion spring is connected between the reel and the side mounting bracket.

[0018] This technical solution achieves an elastic connection between the roller and the side mounting bracket, ensuring smooth operation during the rolling curtain's deployment and retraction, thereby enhancing its operational stability and service life. Specifically, the torsion spring provides the necessary tension during deployment to prevent the curtain from sagging. It also helps reset the roller during retraction, reducing the burden on the motor and extending the life of the drive assembly. Furthermore, the torsion spring provides a certain degree of cushioning against external shock, enhancing the durability of the entire device.

[0019] Preferably, the rolling shutter assembly also includes a leveling rod, which is arranged along the length direction of the long mounting plate and is located between the winding shaft and the pull rod; a first positioning slider and a second positioning slider are respectively provided at both ends of the leveling rod, the first positioning slider is slidingly connected to the first side slide rail, and the second positioning slider is slidingly connected to the first side slide rail.

[0020] By adopting this technical solution, the roller blind assembly maintains a flat curtain fabric during deployment and retraction. Specifically, the design of the flattening rod ensures that the curtain fabric does not wrinkle or twist during movement, thereby enhancing the user experience and aesthetics of the roller blind. Furthermore, the sliding connection between the first and second alignment sliders and the first side rail ensures the stability and reliability of the flattening rod during movement, further enhancing the lifespan and safety of the roller blind.

[0021] Preferably, a side connecting rod is connected between the first side sliding rail and the second side sliding rail, and the side connecting rod is located between the pull rod and the long mounting plate.

[0022] By adopting this technical solution, a secure connection between the first and second side rails is achieved, improving the structural stability of the entire rolling curtain device.

The driving assembly drives the pull rod to slide on the frame, thereby realizing the automatic unfolding and folding of the roller blind, which improves the convenience and safety of use, especially the convenience of operation during driving, avoiding the safety hazards caused by manual operation.

[0025] 2. In this application, the operational flexibility of the roller blind is improved. Through the design of the roller shaft and the pull rod, the roller blind can be evenly unfolded and folded in the width direction of the frame, adapting to different light conditions and meeting the user's sunshade needs in different environments.

[0026] 3. In this application, the stability and reliability of the system are enhanced.

[0041] Reference Figure 1 and Figure 2 The frame 1 includes a long mounting plate 11 and two side mounting brackets 12. The two side mounting brackets 12 are respectively located at both ends of the long mounting plate 11 in the longitudinal direction. Two roller blind assemblies 2 are respectively located on both sides of the long mounting plate 11 in the width direction, and are both located between the two side mounting brackets 12 and connected to the side mounting brackets 12. A reel 21 and a pull rod 24 are both arranged along the length of the long mounting plate 11, with the pull rod 24 located between the reel 21 and the long mounting plate 11. The ends of the reel 21 are rotatably connected to the two side mounting brackets 12, and the ends of the pull rod 24 are slidably connected to the two side mounting brackets 12 in the width direction of the long mounting plate 11.

The first side slider 241 is slidably connected to the first side rail 22, and the second side slider 242 is slidably connected to the first side rail 22.

[0044] Reference Figure 1 and Figure 2 In this embodiment of the present application, the provision of the first side rail 22 and the second side rail 23 ensures that the pull rod 24 has a good guiding effect during sliding, preventing the pull rod 24 from deflecting or getting stuck during movement, thereby improving the operational stability of the rolling shutter assembly 2. Furthermore, the sliding connection between the first side slider 241 and the second side slider 242 and the corresponding rails enables the pull rod 24 to move more smoothly within the frame 1, improving the operational convenience and reliability of the rolling shutter assembly 2. Furthermore, this structural design helps extend the service life of the rolling shutter assembly 2 and reduces wear caused by friction.

[0045] Reference Figure 1 and Figure 2 The drive assembly 3 includes a take-up wheel 32 and a motor 31. The take-up wheel 32 is rotatably mounted on the long mounting plate 11, and a pull rope 33 is connected between the first side slider 241 and the second side slider 242. The motor 31 is connected between the take-up wheel 32 and the long mounting plate 11, and the motor 31 drives the take-up wheel 32 to rotate to reel in and release the line.

[0046] Reference Figure 1 and Figure 2In this embodiment, precise control and synchronized movement of the vehicle's roof roller blind are achieved. Specifically, the arrangement of the take-up wheel 32 enables the pull cord 33 to effectively transmit power, ensuring the synchronous sliding of the first and second side sliders 241, 242. This ensures the consistency and stability of the roller blinds on both sides and prevents stalling or damage caused by uneven force on one side. Furthermore, this design simplifies the drive mechanism, improves system reliability and durability, and reduces maintenance costs.

[0047] Reference Figure 1 and Figure 2 A guide tube 34 is provided over the pull cord 33, which is positioned between the two side mounting brackets 12 and connected to the long mounting plate 11. In this embodiment of the present application, effective guidance and positioning of the pull cord 33 are achieved, ensuring that the pull cord 33 does not deviate or become entangled during movement, thereby improving the stability and reliability of the rolling curtain device. Specifically, the provision of the guide tube 34 allows the pull cord 33 to slide smoothly between the two side mounting brackets 12, preventing uneven deployment or jamming of the rolling curtain caused by loose or stuck pull cord 33, thereby improving user experience and safety.

[0048] Reference Figure 1 and Figure 2 A torsion spring 26 is connected between the reel 21 and the side mounting bracket 12. In the embodiment of the present application, an elastic connection is achieved between the reel 21 and the side mounting bracket 12, ensuring that the roller blind can operate smoothly and smoothly during the unfolding and retraction process, thereby improving the operational stability and service life of the roller blind. Specifically, the provision of the torsion spring 26 can provide the necessary tension when the roller blind is unfolded, preventing the curtain 27 from sagging. At the same time, it helps to reset the reel 21 when the roller blind is retracted, reducing the burden on the motor 31 and extending the service life of the drive assembly 3. In addition, the torsion spring 26 can also buffer external impacts to a certain extent, enhancing the durability of the entire device.

[0049] Reference Figure 1 and Figure 2 The roller blind assembly 2 also includes a leveling rod 25, which is arranged along the length of the long mounting plate 11 and located between the winding shaft 21 and the pull rod 24. The leveling rod 25 is located on the first side rail 22 and on the end of the first side rail 22 away from the long mounting plate 11. A first alignment slider 251 and a second alignment slider 252 are respectively provided at each end of the leveling rod 25. The first alignment slider 251 is slidably connected to the first side rail 22, and the second alignment slider 252 is slidably connected to the first side rail 22.

[0050] Reference Figure 1 and Figure 2In the embodiment of the present application, the leveling rod 25 and the pull rod 24 are coplanar in the horizontal plane. The curtain 27 on the reel 21 passes through the bottom end of the leveling rod 25 and is then connected to the pull rod 24, thereby achieving the effect of keeping the curtain 27 flat during the unfolding and retracting process of the rolling shutter assembly 2.

[0051] Reference Figure 1 and Figure 2 A side link 28 connects the first and second side rails 22, 23. The side link 28 is located between the pull rod 24 and the long mounting plate 11. In this embodiment, a secure connection is achieved between the first and second side rails 22, 23, improving the structural stability of the entire rolling curtain device. Furthermore, the provision of the side link 28 ensures a smoother sliding motion of the pull rod 24, reducing noise and wear caused by unstable sliding, and enhancing the user experience.

[0052] The implementation principle of the automatic rolling curtain device for a car roof in the embodiment of the present application is as follows:

[0053] When the curtain 27 is being unrolled, the motor 31 drives the take-up wheel 32 to rotate, and the take-up wheel 32 performs a take-up action, thereby pulling the first side slider 241 and the second side slider 242 toward the long mounting plate 11, thereby pulling the pull rod 24 toward the long mounting plate 11, and thereby pulling the curtain 27 on the reel 21 toward the long mounting plate 11, thereby unrolling the curtain 27. The leveling rod 25 and the pull rod 24 are coplanar in the horizontal plane, and the curtain 27 on the reel 21 is connected to the pull rod 24 after passing the bottom end of the leveling rod 25. This achieves the effect of keeping the curtain 27 between the leveling rod 25 and the pull rod 24 flat during the unrolling and retracting process of the rolling curtain assembly 2. When the torsion spring 26 is unwinding the reel 21, it can apply a restoring force to the reel 21, thereby ensuring that the curtain 27 between the reel 21 and the pull rod 24 has appropriate tension.

[0054] When the curtain 27 is retracted, the motor 31 drives the take-up wheel 32 to rotate, and the take-up wheel 32 performs the unwinding action. Under the action of the torsion spring 26, the pull rod 24 can move toward the reel 21 by itself to realize the automatic rewinding of the reel 21.
