Technical Field

[0001] This utility model relates to the field of automotive interior parts technology, and in particular to an electric colorful sunshade for a car roof. Background Technology

[0002] With the development of the automotive industry, consumers are increasingly demanding higher functionality and comfort from car interiors. Traditional car sunshades mostly use a single fabric structure, only providing sun shading, and are mostly manually operated, resulting in poor ease of use. While some existing electric sunshades have solved the operation problem, their functions remain relatively limited, lacking personalization and ambiance creation capabilities. Meanwhile, existing illuminated car interior devices are mostly independent light fixtures, requiring additional wiring and installation space, leading to high energy consumption, low integration, and poor adaptability, making it difficult to meet the integrated design requirements of modern car interiors. Furthermore, the limitations of traditional sunshade fabric materials and structural design result in poor performance in light transmission adjustment, durability, and smooth roll-up, failing to balance sun shading effectiveness with users' diverse needs for interior lighting ambiance. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide an electric colorful sunshade for vehicle interiors, which solves the problems of existing sunshades having limited functions, inconvenient operation, lack of atmosphere creation capabilities, and low integration of illuminated interior elements.

[0025] Please see Figure 1 and Figure 2 As shown, this embodiment provides an electric color-changing sunshade for a vehicle's roof, including a curtain body 1, a support structure, and a drive mechanism, wherein:

[0026] The curtain body 1 includes a light-shielding layer and an optical fiber fabric layer on the surface of the light-shielding layer. A pull rod 2 is provided at one end of the curtain body 1. A light source module is provided on the pull rod 2. The optical fiber fabric layer is used to diffuse the light emitted by the light source module and present a light-emitting effect.

[0027] The support structure includes a front frame 3 and a rear shell 4 that are connected to the vehicle frame and arranged opposite to each other. The rear shell 4 is provided with a rotatable roller 5 and has a storage space. The other end of the curtain body 1 is wound around the roller 5. The front frame 3 is provided with a power supply module 6, which is used to supply power to the light source module when the pull rod 2 abuts against the front frame 3.

[0028] The drive mechanism is used to drive the roller 5 to rotate and the pull rod 2 to move, so that the curtain body 1 can be automatically rolled up and unrolled.

[0029] Specifically, the pull rod 2 is an aluminum extrusion part, customized according to the vehicle model, fixed to the edge of the curtain body 1, and integrates a light source module inside it, simplifying the layout; the front frame 3 and the rear shell 4 are both aluminum stamping parts, customized according to the connection position on the vehicle frame, and fixed to the frame with bolts to achieve reliable installation and positioning.

[0030] Therefore, the electric colorful sunshade in the car roof combines electric control, sunshade and colorful lighting functions. In particular, through the fiber optic fabric layer, it can present a variety of lighting effects on the basis of traditional sunshade, which enhances the ability to create atmosphere in the car, solves the problem of the single function of traditional sunshade, and requires little modification to the original car interior structure, is easy to install, and has good adaptability and energy saving.

[0031] In some embodiments, the optical fiber fabric layer is woven from optical fiber filaments and textile threads, and the two sides of the optical fiber fabric layer are fixed by side strips 7.

[0032] The main body of the curtain fabric 1 is customized according to the size of the roof of this vehicle. The fiber optic fabric layer is made by woven 0.25mm diameter fiber optic strands and textile threads in parallel in a specific ratio. The warp yarns are extremely soft threads that are interlaced vertically to achieve a full-surface light-emitting effect and have low-energy light-guiding characteristics. The Teflon-coated edge strips 7 are used to enhance the stability of the edges of the main body of the curtain fabric 1.

[0033] Furthermore, several light leakage points are set on the outer wall of the optical fiber, making the optical fiber fabric layer appear as a starlight curtain.

[0034] Specifically, the outer wall of the optical fiber is treated by physical needle rolling or carbon dioxide laser dotting to give the fabric a starlight effect.

[0035] In some embodiments, one of the power supply module 6 and the light source module is provided with an elastic probe, and the other is provided with a contact spring. When the pull rod 2 abuts against the front frame 3, the elastic probe and the contact spring make contact and conduct.

[0036] The light curtain employs a structure combining a mass-produced standard elastic probe and contact spring. When the curtain body 1 is fully closed, the elastic probe on the pull rod 2 contacts the contact spring on the power supply module 6, thereby connecting the power supply and opening the light curtain. When the curtain body 1 is open, the pull rod 2 separates from the front frame 3, de-energizing the light source module and implementing a "power-on only in working state" logic. Furthermore, the light source module and power supply module 6 are existing technologies and will not be described in detail here.

[0037] In some embodiments, the drive mechanism includes a motor 8 disposed in the roof of the vehicle and a torsion spring disposed on the roller 5. The motor 8 is connected to the pull rod 2 by a cable 9. The motor 8 is used to drive the pull rod 2 to move closer to or away from the front frame 3, and the torsion spring is used to drive the roller 5 to rotate away from the pull rod 2, so as to provide a winding force for the curtain body 1.

[0038] The motor 8 here is a custom-designed motor, containing a control board and transmission gears. The software is customized according to the control requirements of the vehicle model and is used to drive the movement of the pull cable 9. The roller 5 has an aluminum shell, an internal torsion spring and a fixed shaft. The torque is calculated according to the weight and size of the curtain body 1 to ensure smooth curtain retraction. The pull cable 9 is made of carbon steel with a fleece lining. As a soft transmission component, it connects the motor 8 and the pull rod 2 to transmit power. It is customized according to the vehicle model, and the pull cable 9 is covered with a custom steel tube with a length adapted to the pull cable 9 to form a transmission chamber for the pull cable 9, protecting the pull cable 9 and reducing friction. The motor 8 drives the curtain body 1 to open and close, and at the same time, with the action of the torsion spring on the roller 5, it ensures that the curtain body 1 unfolds and retracts smoothly, realizing electric control and improving ease of use.

[0039] Furthermore, the support structure also includes guide rails 10 located on both sides of the front frame 3 and the rear shell 4, with sliders provided in the guide rails 10, and the sliders being fixedly connected to the curtain body 1.

[0040] The guide rail 10 here is an aluminum extrusion part, customized according to the curvature of the car roof, and is used to install the slider and the cable 9. The slider is made of ABS+PP material, one end is connected to the curtain body 1, and the other end is embedded in the guide rail 10, and slides along the guide rail 10 with the cable 9. Through the design of the guide rail 10 and the slider, the movement trajectory of the curtain body 1 is limited, ensuring that the repeated unfolding and rewinding actions of the curtain body 1 are carried out accurately.

[0041] In summary, the electric color-changing sunshade on the roof of this vehicle has the following advantages:

[0042] ① Functional integration: It combines sunshade and colorful light-up functions, and the light effect can be controlled through a mini-program or the car's infotainment system to enhance the atmosphere inside the car and solve the problem of the single function of traditional sunshades;

[0043] ② Easy to operate: It adopts electric control, and the main body of the curtain 1 is driven by motor 8 to roll up and unroll, replacing manual operation and improving the ease of use;

[0044] ③ High adaptability: Each component is customized according to the vehicle model, which can be adapted to the needs of different vehicle models and expand the application range;

[0045] ④ Energy-saving and efficient: The light source is simplified and combined with the light-emitting characteristics of the fiber optic fabric, it reduces energy consumption while ensuring the light-emitting effect, which meets the energy-saving design requirements of modern automobiles.

[0046] ⑤ Stable structure: Made of durable materials such as aluminum and Teflon, with precise fit of each component, ensuring smooth and durable winding and unfolding of the main body of the curtain, thus improving the overall service life;

[0047] ⑥ High safety: The power supply module 6 is reasonably designed, and the power is only connected when the curtain body 1 is closed in place, ensuring electrical safety; the motor 8 and transmission structure are customized and operate stably and reliably.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model.
