[0036] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

These terms are mainly used to better describe the utility model and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0039] In addition, in addition to being used to indicate the orientation or positional relationship, the above-mentioned terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain dependent relationship or connection relationship in some cases. For ordinary skilled persons in the art, the specific meaning of these terms in the utility model can be understood according to the specific situation.

[0040] In addition, the terms "mounting", "setting", "providing", "connecting", "connecting" should be broadly understood. For example, it can be fixedly connected, detachably connected, or integrally constructed; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication between two devices, elements or components. For ordinary skilled persons in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific situation.

[0041] Please refer to Figure 1 The utility model discloses a reel type starry sky roof structure 1, reel type starry sky roof structure 1 includes the roof skylight layer 11, flexible starry sky roof component layer 12 and skin layer 13 that set gradually, reel type starry sky roof structure 1 still includes rolling mechanism 14, and flexible starry sky roof component layer 12 one end and rolling mechanism 14 are connected, and flexible starry sky roof component layer 12 is unfolded or rolled up between roof skylight layer 11 and skin layer 13 relative to rolling mechanism 14.

[0042] It can be understood that the roof sunroof layer 11 provides basic support, and the skin layer 13 plays a role in protecting the flexible starry sky top component layer 12 and decoration. By arranging the laminated structure of the roof sunroof layer 11, the flexible starry sky top component layer 12 and the skin layer 13 in sequence, the flexible starry sky top component layer 12 is attached to the roof sunroof, which greatly simplifies the installation and maximizes the space saving. And one end of the flexible starry sky top component layer 12 is connected with the rolling mechanism 14, so that the flexible starry sky top component layer 12 can be unfolded or rolled up between the roof sunroof layer 11 and the skin layer 13. Compared with the traditional starry sky top which is independently arranged outside the roof, this structure embeds the starry sky top inside the roof. When unfolded, it can create a starry sky atmosphere, and when rolled up, it is completely hidden between the sunroof layer and the skin layer 13, without affecting the lighting. The laminated structure formed by arranging the roof sunroof layer 11, the flexible starry sky top component layer 12 and the skin layer 13 in sequence realizes the effect of low thickness size with the structure characteristics of high integration and integration, improves the space utilization, and releases the space at the top of the car. The space will not be cramped and depressed due to the starry sky top, especially for the vehicle models with limited height inside the vehicle, which greatly improves the passenger's riding experience and enhances the comfort of the vehicle space.

[0043] It should be noted that the traditional starry sky top scheme adopts a scheme of laser or ordinary LED light source cooperating with optical fiber light guide component, or laser projection lamp, or sky screen, etc. The sunroof is two relatively independent structures, the installation structure assembly is complex, occupies a large space inside the vehicle, and also increases the cost. The laminated structure of the roof sunroof layer 11, the flexible starry sky top component layer 12 and the skin layer 13 of the utility model in sequence embeds the starry sky top inside the roof, realizes the effect of low thickness size with the structure characteristics of high integration and integration, and can be rolled up and hidden according to the demand, without affecting the lighting when not in use. It is attached to the roof sunroof to greatly simplify the installation and maximize the space saving, and improves the user's space experience.

[0044] Please refer to Figure 2 , further, the flexible starry sky top component layer 12 includes a flexible bearing layer 121 and a plurality of light emitting chips 122, the light emitting chips 122 are Micro LED or Mini LED chips, and the Micro LED or Mini LED chips are arranged on the flexible bearing layer 121 in a COB packaging manner.

[0045] It can be understood that the flexible carrier layer 121 provides a flexible mounting basis for the Micro LED or Mini LED chips. The chips are arranged on the flexible carrier layer 121 in a COB packaging manner, which can reduce the contact of the chips with the external environment and improve the stability and reliability of the chips. At the same time, the flexible carrier layer 121 makes the entire flexible starry sky top assembly layer 12 flexible, which is convenient for cooperation with the rolling mechanism 14 to realize the unfolding and rolling actions. Compared with traditional light sources, the Micro LED or Mini LED chip has higher light-emitting efficiency, higher brightness and lower energy consumption, and can create a more realistic, bright and energy-saving starry sky effect in the vehicle, further improving the romantic atmosphere and luxury feeling in the vehicle. Moreover, the Micro LED or Mini LED chip is direct display light-emitting, which can realize single-point or super-high partition control. Compared with the non-direct display light-emitting starry sky top display such as the optical fiber starry sky top, the laser projection starry sky top and the sky screen, the contrast and brightness of the Micro LED or Mini LED chip are higher, and the single-point light and dark can be adjusted, which is conducive to realizing intelligent control.

[0046] Please refer to Figures 2 to 4 Further, the Micro LED or Mini LED chip is a flip chip; and / or the arrangement mode of the plurality of Micro LED or Mini LED chips includes single-chip arrangement and / or multi-chip pixelized packaging combination.

[0047] It should be noted that Figure 2 It is shown that the plurality of Micro LED or Mini LED type light-emitting chips 122 adopt a single-chip arrangement arrangement mode; Figure 3 It is shown that the plurality of Micro LED or Mini LED type light-emitting chips 122 adopt a multi-chip pixelized packaging combination arrangement mode; Figure 4 It is shown that the plurality of Micro LED or Mini LED type light-emitting chips 122 adopt a single-chip arrangement and a multi-chip pixelized packaging combination arrangement mode.

[0048] It can be understood that, since the Micro LED or Mini LED chip adopts a flip chip form, the flip chip structure can shorten the connection path of the internal electrode of the chip and the external circuit, reduce the resistance, and thus improve the light-emitting efficiency and heat dissipation performance of the chip. In the flexible starry sky top assembly, better heat dissipation performance can ensure the stability of the chip during long-term use, avoiding brightness attenuation or damage due to overheating. Higher light-emitting efficiency means that brighter light can be provided under the same energy consumption, enhancing the visual effect of the starry sky top and making the simulated starry sky in the vehicle more dazzling. The arrangement of multiple Micro LED or Mini LED chips in a single arrangement and / or multiple chip pixelated packaging combination provides great flexibility for the design of the starry sky top in the vehicle. Single arrangement can achieve finer pixel control and accurately simulate each star in the starry sky, presenting a more realistic starry sky effect. The single light-emitting chip 122 can change the size, color, and brightness of the light spot, and the multiple light-emitting chip 122 pixelated packaging combination can improve the consistency and uniformity of the display effect in scenarios that require large-area display of specific patterns or areas. This diversified arrangement can meet the individual needs of different users for the visual effect of the starry sky top in the vehicle, further improving the user experience. By using Micro LED or Mini LED chips to realize the starry sky top direct display technology scheme, the flexible starry sky top is directly attached to the fixed vehicle sunroof, and the direct display self-luminous does not need to set up a separate light source mounting part, reducing the light guide structure components and making the installation extremely simple and lighter, thereby improving the integration of the starry sky top.

[0049] Further, the thickness of the flexible starry sky top assembly layer 12 is less than or equal to 1.5 mm.

[0050] It can be understood that, since the COB module is integrally packaged and integrated, the size of the flexible starry sky top assembly layer 12 also has the advantages of being ultra-light and ultra-thin. The thickness of the flexible starry sky top assembly layer 12 is less than or equal to 1.5 mm, so that the entire starry sky top occupies very little space when installed in the vehicle. In the case of limited internal space of the roof, the impact on the height of the vehicle interior can be minimized to avoid a sense of oppression for passengers. At the same time, the light and thin structure is also more convenient to cooperate with the rolling mechanism 14, and is more flexible and smooth during unfolding and rolling up, reducing the possibility of jamming due to thick structure and improving the convenience of the starry sky top.

[0051] Please refer to Figure 5 , further, the reel type starry sky top structure 1 further comprises an intelligent adjusting mechanism 15, the intelligent adjusting mechanism 15 comprises an environment sensing device 151 and a control device 152, the vehicle machine system module 20 is signal connected with the environment sensing device 151 and the control device 152, and the control device 152 is signal connected with the flexible starry sky top assembly layer 12.

[0052] It can be understood that the setting of the intelligent adjusting mechanism 15 adds intelligent functions to the starry roof. The environmental sensing device 151 can sense the changes of the vehicle environment in real time, such as light intensity, sound, temperature and other information. The car machine system module 20 is signal connected with the environmental sensing device 151 and the control device 152. When the environmental sensing device 151 detects the change of the environment, it transmits the signal to the car machine system module 20. The car machine system module 20 adjusts the flexible starry roof component layer 12 through the control device 152, and the control device 152 is signal connected with the flexible starry roof component layer 12, so as to adjust the light emitting chip 122 on the flexible starry roof component layer 12, and realize intelligent light effect control.

[0053] Optionally, the car machine system module 20 is signal connected with the environmental sensing device 151 and the control device 152, and controls the light emitting mode of the Mirco or Mini LED module according to the vehicle use scene and the use state of the safety buckle, and intelligently adjusts the custom color of the RGB full-color display.

[0054] Optionally, based on the signal connection between the car machine system module 20 and the environmental sensing device 151 and the control device 152, the starry roof light effect can be programmed and controlled to realize customized display.

[0055] Optionally, the environmental sensing device 151 is arranged in the flexible starry roof component layer 12.

[0056] Optionally, the control device 152 includes an OTA upgrade module to ensure that the light effect supports OTA upgrade push.

[0057] Further, the environmental sensing device 151 includes at least one of a photosensitive sensor, a sound sensor and an infrared sensor.

[0058] It can be understood that, since the environmental sensor includes at least one of a photosensitive sensor, a sound sensor and an infrared sensor, the combination of multiple sensors can comprehensively sense the vehicle environment. The photosensitive sensor can automatically adjust the brightness of the starry roof according to the intensity of external light, so that the starry roof can present the best effect under different light conditions, avoiding both over-bright and over-dark. The sound sensor can capture sound signals in the vehicle, such as music and passenger conversation, so that the starry roof can interact with the sound, increasing the interest and atmosphere. The infrared sensor can detect the activity of the passengers in the vehicle, for example, when there is no one in the vehicle, the starry roof is automatically turned off to save energy; when the passenger enters the vehicle, the starry roof is automatically turned on, and the light emitting mode is adjusted according to the passenger state such as gesture and action, further improving the intelligence and humanization of the starry roof.

[0059] Optionally, the combination of multiple sensors can perceive the environment in the vehicle in all directions, and the control device 152 controls the starry sky top display based on the detection signals of the multiple sensors, such as music rhythm, star constellations, and colorful effects, to improve user experience and technological sense.

[0060] Please refer to Figure 1 Further, the winding mechanism 14 includes a reel assembly 141 and a motor assembly 142, and the reel assembly 141 and the motor assembly 142 are drivingly connected. One end of the reel assembly 141 is connected with the flexible starry sky top assembly layer 12.

[0061] Understandably, the reel assembly 141 and the motor assembly 142 are drivingly connected, and the motor assembly 142 can provide stable power output for the reel assembly 141. One end of the reel assembly 141 is connected with the flexible starry sky top assembly layer 12. When the motor assembly 142 works, it drives the reel assembly 141 to rotate, thereby realizing the unfolding or winding of the flexible starry sky top assembly layer 12. The design structure of such a winding mechanism 14 is simple and reliable, and can accurately control the unfolding and winding speed of the flexible starry sky top assembly layer 12, and is easy to operate. At the same time, the motor assembly 142 can be controlled through the car machine system module 20, and the user can easily realize the folding and unfolding operation of the starry sky top in the vehicle, thereby improving the convenience of use for the user.

[0062] Please refer to Figure 6 Further, the reel-type starry sky top structure 1 further includes a limiting mechanism 16, the limiting mechanism 16 is connected with the roof sunroof layer 11, and the flexible starry sky top assembly layer 12 is movably connected with the limiting mechanism 16.

[0063] Understandably, the limiting mechanism 16 can constrain the position of the flexible starry sky top assembly layer 12 during the unfolding and winding process, to ensure the accuracy and stability of the movement track. It avoids the flexible starry sky top assembly layer 12 from deviating or twisting during the movement process, thereby prolonging the service life of the flexible starry sky top assembly layer 12, ensuring that the starry sky top can work normally and stably, and also ensuring the flatness of the starry sky top. The limiting mechanism 16 also helps to improve the smoothness of the operation of the winding mechanism 14 and reduce the additional load on the winding mechanism 14 caused by the position deviation of the flexible starry sky top assembly layer 12.

[0064] Please continue to refer to Figure 6 Further, the limiting mechanism 16 includes a pair of parallel guide rails 161, the guide rails 161 are respectively arranged on both sides of the roof sunroof layer 11, and the flexible starry sky top assembly layer 12 includes a flexible bearing layer 121. The two sides of the flexible bearing layer 121 are provided with structure reinforcing assemblies 1211 corresponding to the guide rails 161.

[0065] It can be understood that the guide rail 161 provides precise guidance for the movement of the flexible starry sky top assembly layer 12, so that the flexible starry sky top assembly layer 12 can move smoothly along the guide rail 161 during the unfolding and rolling up process, further ensuring the stability and accuracy of the movement. The structural reinforcement assembly 1211 not only enhances the strength of the two sides of the flexible bearing layer 121, enabling it to better cooperate with the guide rail 161, but also protects the flexible bearing layer 121 to some extent, preventing damage caused by friction, pulling and other reasons during movement. Through the cooperation of the guide rail 161 and the structural reinforcement assembly 1211, the reliability and durability of the entire reel type starry sky top structure 1 are effectively improved.

[0066] Optionally, the structural reinforcement assembly 1211 is a reinforcing rib.

[0067] Please refer to Figure 7 The second embodiment of the utility model provides a vehicle 100, which comprises a sunroof 101, and the sunroof 101 is internally provided with the reel type starry sky top structure 1 of the first embodiment of the utility model.

[0068] It can be understood that the vehicle 100 has the same beneficial effects as the reel type starry sky top structure 1 of the first embodiment of the utility model, and will not be described here.

[0069] Compared with the prior art, the reel type starry sky top structure and the vehicle of the utility model have the following advantages:

[0070] 1、the reel type starry sky top structure in an embodiment of the utility model comprises a roof sunroof layer, a flexible starry sky top assembly layer and a skin layer arranged in sequence, and further comprises a rolling mechanism, one end of the flexible starry sky top assembly layer is connected with the rolling mechanism, and the flexible starry sky top assembly layer is unfolded or rolled up relative to the rolling mechanism between the roof sunroof layer and the skin layer. The roof sunroof layer provides basic support, and the skin layer plays a role in protecting the flexible starry sky top assembly layer and decoration. By arranging the laminated structure in which the roof sunroof layer, the flexible starry sky top assembly layer and the skin layer are arranged in sequence, the flexible starry sky top assembly layer is attached to the roof sunroof layer, thereby simplifying the installation and maximizing the space saving. Furthermore, one end of the flexible starry sky top assembly layer is connected with the rolling mechanism, so that the flexible starry sky top assembly layer can be unfolded or rolled up between the roof sunroof layer and the skin layer. Compared with the traditional starry sky top which is independently arranged on the outside of the roof, this structure embeds the starry sky top in the roof interior, can create a starry sky atmosphere when unfolded, and is completely hidden between the sunroof layer and the skin layer when rolled up, without affecting the lighting. The laminated structure formed by the roof sunroof layer, the flexible starry sky top assembly layer and the skin layer arranged in sequence has the structural feature of high integration, realizes the effect of low thickness size, improves the space utilization rate, and releases the space at the top of the vehicle, so that the vehicle does not appear cramped and depressed due to the starry sky top. Especially for the vehicle model with limited height in the vehicle, the passenger's riding experience is greatly improved, and the comfort of the vehicle space is improved.

[0071] 2、The flexible starry sky top assembly layer in an embodiment of the utility model includes a flexible bearing layer and a plurality of light emitting chips, the light emitting chips are Micro LED or Mini LED chips, and the Micro LED or Mini LED chips are arranged on the flexible bearing layer in a COB packaging mode. The flexible bearing layer provides a flexible mounting basis for the Micro LED or Mini LED chips. The chips are arranged on the flexible bearing layer in the COB packaging mode, and the COB packaging can reduce the contact of the chips with the external environment and improve the stability and reliability of the chips. Meanwhile, the flexible bearing layer makes the entire flexible starry sky top assembly layer flexible, facilitating cooperation with the rolling mechanism to realize the actions of unfolding and rolling up. Compared with traditional light sources, the Micro LED or Mini LED chips have higher light emitting efficiency, higher brightness and lower energy consumption, can create a more realistic, bright and energy-saving starry sky effect in the vehicle, and further improve the romantic atmosphere and luxury feeling in the vehicle. Moreover, the Micro LED or Mini LED chips are direct display light emitting, can realize single-point or super-high partition control, have higher contrast and brightness than the non-direct display light emitting starry sky top display such as a fiber starry sky top, a laser projection starry sky top and a sky screen, and can be adjusted in single-point light and dark, which is beneficial to realize intelligent control.

[0072] 3、The Micro LED or Mini LED chip in an embodiment of the utility model is a flip chip; and / or the arrangement mode of the plurality of Micro LED or Mini LED chips includes single-chip arrangement and / or multi-chip pixelized packaging combination. Since the Micro LED or Mini LED chip adopts the form of flip chip, the flip chip structure can shorten the connection path of the internal electrode of the chip and the external circuit, reduce the resistance, and thus improve the light emitting efficiency and heat dissipation performance of the chip. In the flexible starry sky top assembly, better heat dissipation performance can ensure the stability of the chip during long-time use, avoiding brightness attenuation or damage caused by overheating. Higher light emitting efficiency means that brighter light can be provided under the same energy consumption, enhancing the visual effect of the starry sky top and making the simulated starry sky in the vehicle more dazzling. The arrangement mode of the plurality of Micro LED or Mini LED chips in single-chip arrangement and / or multi-chip pixelized packaging combination provides great flexibility for the design of the starry sky top in the vehicle. Single-chip arrangement can realize finer pixel control and accurately simulate each star in the starry sky, presenting a more realistic starry sky effect. Multi-chip pixelized packaging combination can improve the consistency and uniformity of the display effect in some scenes requiring large-area display of specific patterns or areas. This diversified arrangement mode can meet the individualized needs of different users for the visual effect of the starry sky top in the vehicle, further improving the user experience.

[0073] 4、The thickness of the flexible starry sky top assembly layer in one embodiment of the utility model is less than or equal to 1.5mm. Due to the adoption of the COB module integrated packaging technology, the extremely simple installation can be realized, and the size of the flexible starry sky top assembly layer also has the advantages of ultra-light and ultra-thin. The thickness of the flexible starry sky top assembly layer is less than or equal to 1.5mm, so that the space occupied by the entire starry sky top is extremely small when being installed in the vehicle. In the case that the internal space of the vehicle roof is limited, the influence on the height of the vehicle interior can be reduced to the maximum extent, and the passengers are prevented from feeling depressed. Meanwhile, the light and thin structure is also more convenient for cooperating with the rolling mechanism, and the rolling and unrolling process is more flexible and smooth, the jamming phenomenon possibly caused by the thick structure is reduced, and the use convenience of the starry sky top is improved.

[0074] 5、The spool type starry sky top structure in one embodiment of the utility model further comprises an intelligent adjusting mechanism, the intelligent adjusting mechanism comprises an environment sensing device and a control device, the vehicle machine system module is signal connected with the environment sensing device and the control device, and the control device is signal connected with the flexible starry sky top assembly layer. The intelligent adjusting mechanism adds the intelligent function to the starry sky top. The environment sensing device can sense the changes of the vehicle interior environment in real time, such as light intensity, sound, temperature and the like. The vehicle machine system module is signal connected with the environment sensing device and the control device, when the environment sensing device detects the environmental change, the signal is transmitted to the vehicle machine system module, the vehicle machine system module adjusts the flexible starry sky top assembly layer through the control device, the control device is signal connected with the flexible starry sky top assembly layer, and then the light emitting chip on the flexible starry sky top assembly layer is adjusted, so that the intelligent light effect control is realized.

[0075] 6、The environment sensing device in one embodiment of the utility model comprises at least one of a photosensitive sensor, a sound sensor and an infrared sensor. Due to the fact that the environment sensor comprises at least one of the photosensitive sensor, the sound sensor and the infrared sensor, the combination of the multiple sensors can comprehensively sense the vehicle interior environment. The photosensitive sensor can automatically adjust the brightness of the starry sky top according to the intensity of external light, so that the starry sky top can present the best effect under different light conditions, avoiding both the dazzling of too much light and the inability to see due to too little light. The sound sensor can capture the sound signals in the vehicle, such as music and passenger conversation, so that the starry sky top can interact with the sound, increasing the interest and atmosphere. The infrared sensor can detect the activity of the personnel in the vehicle, for example, when there is no one in the vehicle, the starry sky top is automatically turned off to save energy; when the passenger enters the vehicle, the starry sky top is automatically turned on, and the light emitting mode is adjusted according to the passenger state such as gestures and actions, so that the intelligent and humanized degree of the starry sky top is further improved.

[0076] 7、The winding mechanism in an embodiment of the utility model comprises a reel assembly and a motor assembly, the reel assembly and the motor assembly are in transmission connection, one end of the reel assembly is connected with the flexible starry sky top assembly layer. The reel assembly and the motor assembly are in transmission connection, the motor assembly can provide stable power output for the reel assembly. One end of the reel assembly is connected with the flexible starry sky top assembly layer, when the motor assembly works, the reel assembly is driven to rotate, so that the expansion or winding of the flexible starry sky top assembly layer is realized. The design structure of this winding mechanism is simple and reliable, the expansion and winding speed of the flexible starry sky top assembly layer can be accurately controlled, and the operation is convenient. Meanwhile, the motor assembly can be controlled through the vehicle system module, the user can easily realize the folding and unfolding operation of the starry sky top in the vehicle, and the convenience of use is improved.

[0077] 8、The reel type starry sky top structure in an embodiment of the utility model further comprises a limiting mechanism, the limiting mechanism is connected with the roof window layer, and the flexible starry sky top assembly layer is movably connected with the limiting mechanism. The limiting mechanism can constrain the position of the flexible starry sky top assembly layer during the expansion and winding process, and ensure the accuracy and stability of the movement track. The deviation and distortion of the flexible starry sky top assembly layer during the movement process are avoided, so that the service life of the flexible starry sky top assembly layer is prolonged, the normal and stable operation of the starry sky top is ensured, and the flatness of the starry sky top is also ensured. The setting of the limiting mechanism also helps to improve the smoothness of the operation of the winding mechanism and reduce the additional load of the winding mechanism caused by the position deviation of the flexible starry sky top assembly layer.

[0078] 9、The limiting mechanism in an embodiment of the utility model comprises a pair of parallel guide rails, the guide rails are arranged on the two sides of the roof window layer respectively, the flexible starry sky top assembly layer comprises a flexible bearing layer, and structure reinforcing assemblies corresponding to the guide rails are arranged on the two sides of the flexible bearing layer.
