[0025] This application proposes a luminous sunshade curtain.
[0026] Please refer to Figures 1 to 3 , Figure 8 In one embodiment of this application, the luminous sunshade is applied to a vehicle, and the luminous sunshade includes: The drum 200 is configured to be rotatably mounted on the body of a vehicle, and the drum 200 is provided with a terminal portion 220 including a plurality of moving terminals 221; The curtain body 100 has one edge fixed to the roller 200, and the outer surface of the curtain body 100 is provided with a light-blocking layer 110. Multiple light-emitting elements 150 are distributed on the inner side of the curtain body 100, and a movable terminal 221 is electrically connected to at least one light-emitting element 150. A fixed shaft 300 is configured to be fixed to the vehicle body and sleeved with a terminal portion 220. The fixed shaft 300 has multiple conductive rings 310 distributed along its axial direction, and each conductive ring 310 is electrically connected to a movable terminal 221. The controller 404 is electrically connected to the conductive ring 310 to control the light-emitting state of multiple light-emitting elements 150 and form a preset pattern.
[0027] The technical solution of this application provides a light-shielding layer 110 on the outer side of the curtain body 100. When the roller rotates, the curtain body 100 can be unfolded to utilize the light-shielding layer 110 for blocking. Multiple light-emitting elements 150 are provided on the inner side of the curtain body 110. These light-emitting elements 150 are controlled by the controller 404 to form a preset luminous pattern. Each light-emitting element 150 is electrically connected to a movable terminal 221 in a terminal portion 220 at the end of the roller 200. This terminal portion 220 forms a sleeve-fit relationship with a fixed shaft 300 fixed to the vehicle body and not rotatable. Each conductive ring 310 distributed axially on the fixed shaft 300 corresponds to a movable terminal 221, ensuring that the movable terminal 221 maintains sliding electrical contact with the corresponding conductive ring 310 during the rotation of the roller 200. The controller 404 electrically connects each conductive ring 310 or movable terminal 221, thereby providing an independent power supply and control signal path for each light-emitting element 150. Thus, even during the repeated unfolding or rewinding of the curtain body 100, each light-emitting element 150 can still stably receive control commands through the conductive ring 310 – moving terminal 221 slip ring structure, presenting different light-emitting states and realizing preset patterns such as individual lighting, dimming, flashing, or combination into dynamic patterns. This not only retains the original light-blocking function of the sunshade curtain and enables it to be integrated with a highly flexible starry sky ceiling, but also avoids the problem of the wires connecting the light-emitting elements 150 getting tangled or broken during the rotation of the roller 200, thereby improving the user's experience with the sunshade curtain.
[0028] It should be noted that each movable terminal 221 is electrically connected to at least one light-emitting element 150. This connection can be one movable terminal 221 and one light-emitting element 150, or two or three light-emitting elements 150 and one movable terminal 221. Thus, one movable terminal 221 can control the light-emitting state of one or more light-emitting elements 150. By controlling the electrical connection between different movable terminals 221 and the conductive ring 310, the light-emitting state of the corresponding light-emitting element 150 can be controlled. The controller 404 is electrically connected to the conductive ring 310. This can be understood as the controller 404 being directly electrically connected to the conductive ring 310 via a wire, or it can be directly electrically connected to the terminal portion 220 via a wire. Furthermore, the body of the fixed shaft 300 is non-conductive, while the conductive ring 310 on the fixed shaft 300 is electrically connected to the vehicle power supply, vehicle controller, etc., via wires. The controller 404 can be integrated into the vehicle's infotainment system or independently mounted on the luminous sunshade. Without loss of generality, the axial and circumferential directions referred to in this solution refer to the orientation of the roller 200. For example, the axial direction is the extension direction of the roller 200, the outer side of the curtain body 100 is the side facing outwards from the vehicle, and the inner side of the curtain body 100 is the side facing inwards from the vehicle interior. The luminous sunshade can be installed on the roof 500, or on the rear windshield or window glass, etc.
[0029] In one embodiment, please refer to Figure 2 and Figure 3 The conductive ring 310 is disposed on the outer periphery of the fixed shaft 300, and the terminal portion 220 is sleeved on the outside of the fixed shaft 300. It can be understood that the fixed shaft 300 is fixedly installed on the vehicle body, and a plurality of electrically insulated conductive rings 310 are disposed at axial intervals on its outer periphery; one end of the drum 200 is provided with a terminal portion 220, which is coaxially sleeved on the outer periphery of the fixed shaft 300, so that the plurality of moving terminals 221 of the terminal portion 220 respectively form sliding electrical contact with the corresponding conductive ring 310. The curtain body 100 is fixed to the roller 200 on one side. The curtain body 100 has a flexible circuit board or conductive film, and multiple light-emitting elements 150 are arranged on the flexible circuit board or conductive film. This allows each light-emitting element 150 to be independently electrically connected to a moving terminal 221 through the circuit structure of the flexible circuit board or conductive film. The controller 404 is connected to each conductive ring 310 or each moving terminal 221 through leads. Thus, during the process of the roller 200 rotating relative to the fixed shaft 300 to unfold or rewind the curtain body 100, each light-emitting element 150 can still be provided with independent and continuous power supply and control signals through the stable sliding contact between the conductive ring 310 and the moving terminal 221. Of course, in other embodiments, the terminal part 220 may also include a ring-shaped or rod-shaped body, with multiple moving terminals 221 distributed axially along the outer periphery of the body. The fixed shaft 300 is a hollow structure, and the conductive ring 310 is fixed to the inner periphery of the fixed shaft 300, presenting a conductive sleeve outside the terminal part 220.
[0030] Specifically, the number of multiple conductive rings 310 and multiple moving terminals 221 is the same, which can be 20, 50 or 100. The number of multiple light-emitting elements 150 can also be the same as the number of multiple conductive rings 310 or multiple moving terminals 221. For example, when the number of conductive rings 310 or moving terminals 221 is 50, the number of light-emitting elements 150 is 50. Alternatively, multiple light-emitting elements 150 can be configured as a group, and a group of light-emitting elements 150 includes 2, 5 or 10 light-emitting elements. Multiple groups of light-emitting elements 150 can also be the same as the number of multiple conductive rings 310 or multiple moving terminals 221. For example, when the number of conductive rings 310 or moving terminals 221 is 20, the curtain body 100 includes 20 groups of light-emitting elements 150.
[0031] Furthermore, in this embodiment, please refer to Figure 2 and Figure 3 The fixed shaft 300 has a hollow structure and is coaxially arranged with the drum 200. One end of the fixed shaft 300 has an inlet 320 that extends through the interior. The conductive rings 310 can be electrically connected to an external power source through wires passing through the inlet 320. Each conductive ring 310 is electrically connected to the controller 404 or a power source through wires passing through the inlet 320 and extending along the inner cavity of the fixed shaft 300. The power source provides power to the light-emitting element 150. The wires can be bundled together. Since the fixed shaft 300 is fixed to the vehicle body and does not rotate with the drum 200, the wires can be stably introduced from the inlet 320 without being subjected to repeated bending or torsional stress, thus avoiding the wear, breakage, or contact failure problems that easily occur with external wiring during frequent opening and closing of the sunshade. At the same time, the hollow structure of the fixed shaft 300 allows the power supply line to be built inside, providing protection for the wires and enhancing the reliability and safety of the electrical connection. Of course, in other embodiments, the sidewall of the fixed shaft 300 may also be embedded with conductive lines, and the end of the fixed shaft 300 away from the conductive ring 310 is an electrically plug-in structure, which is used to electrically connect to the power supply or controller 404 outside the drum 200 by electrical plug-in, thereby improving the convenience of assembly.
[0032] In one embodiment, please refer to Figure 2 and Figure 3One end of the fixed shaft 300 is fixed to the vehicle body, and the other end is provided with a conductive ring 310. The fixed shaft 300 is inserted axially into the roller 200, which has a wiring notch 210. The moving terminal 221 is located inside the roller 200 and is electrically connected to the light-emitting element 150 through a wiring harness 402, which passes through the wiring notch 210. Without loss of generality, one end of the fixed shaft 300 is provided with a fixing seat 330. When the luminous sunshade is installed on the roof 500, the fixing seat 330 is connected to the sunroof frame 510. The end of the fixed shaft 300 inserted into the roller 200 is the insertion end, and the outer periphery of the insertion end is provided with multiple axially distributed conductive rings 310. The roller 200 has a wiring notch 210 on its peripheral wall, and the moving terminal 221 located inside the roller 200 is electrically connected to each light-emitting element 150 on the curtain body 100 through the wiring harness 402. The wiring harness 402 passes through the inner cavity of the drum 200 and is led to the curtain body 100 via the wiring notch 210. When the drum 200 rotates relative to the fixed shaft 300 to unfold or retract the curtain body 100, the movable terminal 221 provided on the inner wall of the drum 200 always maintains sliding electrical contact with the corresponding conductive ring 310 on the fixed shaft 300. The controller 404 connects each conductive ring 310 through wires, and then independently transmits power and control signals to each light-emitting element 150 via the movable terminal 221 and the wiring harness 402. The wiring notch 210 can be covered by the curtain body 100 after it is rolled up, ensuring the stability of the wiring harness 402 connecting the movable terminal 221 and the light-emitting element 150. Of course, in other embodiments, the end of the drum 200 may be provided with a fixed rod, on which multiple movable terminals 221 of the terminal portion 220 are distributed, so that the movable terminal 221 and the fixed shaft 300 are sleeved outside the drum 200 to complete electrical conduction.
[0033] Furthermore, in this embodiment, please continue to refer to... Figure 2 and Figure 3The luminous sunshade also includes a housing 230, which is fixed inside the roller 200 and spaced outwards on the fixed shaft 300. A terminal portion 220 is fixed to the inner circumference of the housing 230, and a wire outlet 231 is provided on the housing 230, communicating with a wiring notch 210. Without loss of generality, the fixed shaft 300 is inserted into the housing 230, and a connecting seat 232 is provided on one side of the housing 230. The connecting seat 232 is fixedly connected to the roller 200, so that the housing 230 is independently fixedly installed inside the roller 200 and spaced outwards on the outer circumference of the fixed shaft 300 in a coaxial manner. A terminal portion 220 is fixedly provided on the inner circumferential surface of the housing 230, and the terminal portion 220 consists of multiple movable terminals 221. Each movable terminal 221 slides in contact with a corresponding conductive ring 310 on the outer circumference of the fixed shaft 300 to achieve electrical connection. Meanwhile, the housing 230 has a cable outlet 231 on its peripheral wall. The cable outlet 231 is aligned with and connected to the cable routing notch 210 on the drum 200, so that the wire bundle 402 led out from the terminal part 220 can pass through the cable outlet 231 and the cable routing notch 210 to the curtain body 100, and then be electrically connected to each light-emitting element 150. In this way, by integrating the terminal part 220 into the inner periphery of the housing 230, not only is the coaxiality and contact stability of the fit between the moving terminal 221 and the conductive ring 310 improved, but the housing 230 also provides support and protection for the internal electrical connection components such as the terminal part 220 and the conductive ring 310.
[0034] In one embodiment, please refer to Figure 4 and Figure 5The luminous sunshade also includes a movable rod 401, which is connected to the end of the curtain body 100 away from the roller 200. A controller 404 is disposed adjacent to the movable rod 401. The output end of the controller 404 is electrically connected to a plurality of light-emitting elements 150, and the input end of the controller 404 is electrically connected to a plurality of moving terminals 221 through a wiring harness 402. The movable rod 401 is fixedly connected to the end of the curtain body 100 away from the roller 200 and slidably connected to the guide rail 520 on the vehicle body. It is used to guide the curtain body 100 to move smoothly during the unfolding or rolling of the sunshade. The controller 404 is located adjacent to the movable rod 401 and is electrically connected to multiple light-emitting elements 150 on the curtain body 100 through its output end to realize independent control of each light-emitting element 150. At the same time, the input end of the controller 404 is electrically connected to multiple moving terminals 221 through the wiring harness 402. Each moving terminal 221 maintains sliding electrical contact with the corresponding conductive ring 310 on the outer periphery of the fixed shaft 300, thereby obtaining power and control signals from an external power source or vehicle system through the conductive ring 310. On the one hand, the wiring distance between the controller 404 and the light-emitting element 150 is shortened, reducing the risk of signal attenuation and electromagnetic interference, and improving the control response speed and stability. On the other hand, through the sliding electrical connection structure of the moving terminal 221-conductive ring 310, even during the continuous rotation of the drum 200 and the dynamic extension and retraction of the curtain body 100, the controller 404 can be ensured to continuously obtain stable power supply and communication signals.
[0035] Specifically, in this embodiment, please continue to refer to... Figure 4 and Figure 5The wiring harness 402 is connected to the side of the light-shielding layer 110 away from the light-emitting element 150 by adhesive bonding. Multiple light-emitting elements 150 are disposed on a conductive film, which is electrically connected to the output terminal of the controller 404. The conductive film has good bendability and conductivity stability, and is configured in a film shape, allowing multiple light-emitting elements 150 to be distributed on it. Flexible conductive elements 403 are disposed along its edges, allowing the flexible conductive elements 403 to be electrically connected to the multiple light-emitting elements 150. Furthermore, the flexible conductive elements 403 are folded over the side of the movable rod 401 away from the controller 404 to bypass the movable rod 401 and then electrically connect to the output terminal of the controller 404, thereby enabling the controller 404 to supply power and independently control each light-emitting element 150. Simultaneously, the wiring harness 402, used for conducting electricity and transmitting electrical signals, is fixed to the side of the light-shielding layer 110 away from the light-emitting element 150 by adhesive bonding, i.e., located between the light-shielding layer 110 and the skylight. On the one hand, by using conductive films instead of rigid circuit boards or discrete wires, the light-emitting element 150 can bend freely with the curtain body 100 during the winding and unfolding process without breaking or poor contact, thus improving the durability and flexibility of the electrical connection. On the other hand, by adhesively fixing the wire harness 402 to the back of the light-shielding layer 110, the wire harness 402 is not exposed and affects the appearance, and it is also prevented from interfering or rubbing with the roller 200, movable rod 401 or other structures during the movement of the curtain, thus avoiding signal interruption or short circuit problems caused by loosening, displacement or wear of the wire harness 402.
[0036] In another embodiment, please refer to Figure 6 and Figure 7 The vehicle includes a power supply for powering the light-emitting elements. A controller 404 is located between the fixed shaft 300 and the power supply, and is electrically connected to both the power supply and the conductive rings 310 via wires. Specifically, the power output from the power supply is processed by the controller 404, then transmitted to each conductive ring 310 via wires, and finally to multiple light-emitting elements 150 via the moving terminal 221 (which slides in contact with the conductive ring 310) and the flexible conductive element 4. Placing the controller 404 in a stationary area near the fixed shaft 300 avoids its movement with the rotation of the drum 200, simplifying the wiring structure and preventing the controller 404 from being disturbed by vibrations caused by repeated winding of the curtain body 100. Simultaneously, as an intermediate control node between the power supply and the conductive rings 310, the controller 404 can regulate, modulate, or logically distribute the input power, enabling independent control of each light-emitting element 150 upstream of the energized conductive ring 310. This reduces the energized load between the conductive ring 310 and the moving terminal 221, improving the durability and stability of the electrical connection.
[0037] In one embodiment, please refer to Figure 1 and Figure 8The controller 404 acquires a preset signal and controls the light-emitting state of multiple light-emitting elements 150 according to the preset signal. The preset signal includes at least one of the vehicle motion state, driver heart rate information, and sound direction. Specifically, when the vehicle is turning, the controller 404 receives the turning signal from the vehicle's CAN bus and drives the light-emitting element 150 on the curtain body 100 to synchronously simulate the movement effect of the starry sky roof along a predetermined trajectory. This allows the luminous sunshade assembly to dynamically change synchronously during vehicle movement, enhancing the experience for drivers and passengers. When the driver's heart rate sensor detects an abnormal or significant fluctuation in heart rate, the controller 404 adjusts the color and brightness of the light-emitting element 150 in real time based on the received heart rate information. For example, the color of the light-emitting element 150 gradually changes from a cool color to a warm color, and the brightness becomes a soft flash or gradually brightens, providing emotional comfort or warning feedback. When the in-vehicle audio system plays a sound source, the controller 404 controls the light-emitting element 150 in the corresponding area to gradually diffuse light outward from the sound source position along the curtain surface based on the spatial audio data output by the sound location recognition module, forming a dynamic light effect consistent with the direction of sound propagation. This helps drivers and passengers determine the location of abnormal noises or identify the person they are communicating with, facilitating communication or maintenance. Thus, this embodiment integrates multi-source environmental and physiological information into the control logic of the luminous sunshade, making the sunshade no longer just a light-blocking function, but a dynamic atmosphere carrier that is perceptible, responsive, and interactive in the smart cockpit. This solves the problem of existing automotive sunshades having a single function and lacking contextual adaptability, while improving the human-vehicle interaction experience, enhancing driving safety and the technological feel of the cockpit.
[0038] In one embodiment, please refer to Figures 4 to 7The curtain body 100 also includes a light-emitting layer 130, which is located inside the curtain body 100, with multiple light-emitting elements 150 distributed within the light-emitting layer 130. It can be understood that the curtain body 100 is composed of a multi-layered composite structure, including a light-emitting layer 130 located on the side facing the interior of the carriage. Multiple light-emitting elements 150 are evenly or distributed in a preset pattern within the light-emitting layer 130, such as squares or circles, to emit controllable light when powered on, creating ambient lighting or dynamic lighting effects. Alternatively, the curtain body 100 includes a reflective layer 120, which is superimposed on the inner side of the light-blocking layer 110. The reflective layer 120 has a reflective pattern on one side of the light-blocking layer 110. The reflective layer 120 can reflect highly recognizable graphics or logos under ambient light, and can also reflect patterns when the light-emitting elements 150 are lit. Alternatively, the curtain body 100 may include both a light-emitting layer 130 and a reflective layer 120. From the outside to the inside of the curtain body 100, the layers are, in sequence, a light-blocking layer 110, a reflective layer 120, and a light-emitting layer 130, with the light-emitting element 150 located within the light-emitting layer 130. The square, as described above, can be the reflective pattern of the reflective layer 120, and the circle can be the light-emitting pattern of the light-emitting layer 130. Thus, by placing the light-emitting layer 130 on the inside, soft and even light is projected into the passenger compartment. The reflective layer 120 enhances the flexibility of the patterns that the luminous sunshade can display, thereby improving the user experience of the luminous sunshade.
[0039] Furthermore, in this embodiment, please refer to Figures 4 to 7 The curtain body 100 also includes a fabric layer 140, which is disposed on the inner side of the curtain body 100. It should be noted that the fabric layer 140 is located at the innermost part of the curtain body 100, directly facing the passenger compartment as the innermost layer. The fabric layer 140 is made of a flexible textile material with controllable light transmittance, possessing both excellent light diffusion performance and skin-friendly, low-reflective, and sound-absorbing properties. When multiple light-emitting elements 150 are illuminated within the light-emitting layer 130, the light is evenly diffused through the fabric layer 140, creating a soft, glare-free ambient lighting effect, enhancing visual comfort and the cabin's premium feel. Simultaneously, the fabric layer 140 effectively conceals the internal circuitry and the arrangement of the light-emitting elements 150, preventing exposed electronic components from affecting aesthetics, and providing a warmer, more home-like interior experience in terms of touch. In this way, the fabric layer 140 can also work in conjunction with the light-shielding layer 110, the reflective layer 120, and the reflective layer 120 to ensure the functions of sunshade and dynamic light emission while taking into account acoustic optimization and passenger safety, thus ensuring the user experience of drivers and passengers.
