[0086] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0087] Reference Figures 1 to 11 As shown, as a first aspect of the present application, the present application provides a vehicle roof skylight 100 , comprising: a light-transmitting body 110 and a light-changing body 130 .

[0088] Among them, reference Figure 5 As shown, the light-transmitting body 110 is used to cover the roof and allow light to pass through; the light-changing body 130 is arranged inside the light-transmitting body 110 and can move relative to the light-transmitting body 110. Figure 5 As shown, the light-changing body 130 includes a first light-changing area 131 and a second light-changing area 132. The first light-changing area 131 can make the light passing through the light-transmitting body 110 present a first type of light-changing effect in the vehicle cabin; the second light-changing area 132 can make the light passing through the light-transmitting body 110 present a second type of light-changing effect in the vehicle cabin.

[0089] When the light modulator 130 moves so that the first light-changing area 131 corresponds to the light-transmitting area of the light-transmitting body 110 (the light-transmitting body 110 may also have a non-light-transmitting area), the light passing through the light-transmitting area of the light-transmitting body 110 will produce a change in light after passing through the light modulator 130, thereby forming a lighting state in the vehicle cabin that corresponds to the first light-changing area 131.

[0090] When the light modulating body 130 moves so that the second light modulating area 132 corresponds to the light transmissive area of the light transmissive body 110, the light passing through the light transmissive area of the light transmissive body 110 will change after passing through the light modulating body 130, thereby forming a lighting state in the vehicle cabin that corresponds to the second light modulating area 132.

[0091] Of course, the lighting condition in the vehicle compartment is not entirely determined by the light modifier 130 , but is comprehensively determined by the light source (such as natural light, lamplight, vehicle-mounted lighting, etc.) and the light transmissive body 110 .

[0092] However, under the same light source and the same light-transmitting element 110, that is, under the same light conditions incident on the light modulating element 130, the light modulating effects produced by the light passing through the first light-modifying area 131 and the second light-modifying area 132 are different. Therefore, the collection of multiple light-modifying effects produced by light passing through the first light-modifying area 131 (due to the changes in the incident light, the same applies below) is referred to as the first type of light-modifying effect, while the collection of multiple light-modifying effects produced by light passing through the second light-modifying area 132 is referred to as the second type of light-modifying effect.

[0093] Therefore, the technical solution provided in the present application presents the first type of light-changing effect or the second type of light-changing effect in the vehicle cabin by switching to the first light-changing area 131 or the second light-changing area 132 corresponding to the light-transmitting area or part of the light-transmitting area of the light-transmitting body 110 through the movement of the light-changing body 130.

[0094] It should be noted that the first type of light-changing effect presented in the car cabin as referred to in this application refers to the first type of light-changing effect presented in all or part of the car cabin, that is, the first light-changing area 131 can occupy all the light-transmitting areas of the light-transmitting body 110; or it can only occupy part of the light-transmitting area of the light-transmitting body 110, and the other part is occupied by the second light-changing area 132, thereby presenting two composite light-changing effects in the car cabin at the same time.

[0095] As a specific solution, the areas of the first light-changing region 131 and the second light-changing region 132 are greater than or equal to the area of the light-transmitting region of the light-transmitting body 110. In this case, the light-changing body 130 can be moved to switch between the first light-changing region 131 and the second light-changing region 132, thereby switching the entire vehicle interior to the first or second light-changing effect.

[0096] As a specific solution, the areas of the first light-changing region 131 and the second light-changing region 132 can be smaller than the area of the light-transmitting region of the light-transmitting body 110. In this case, by moving the light-changing body 130, the first light-changing region 131 or the second light-changing region 132 can simultaneously provide the entire vehicle interior with the first or second light-changing effect.

[0097] Although the first light-changing region 131 or the second light-changing region 132 can simultaneously produce the first or second light-changing effect by moving the light-changing member 130 when the area is equal to or greater than the area of the light-transmitting region of the light-transmitting member 110, only two light-changing effects can be produced in this manner. If the areas of the first light-changing region 131 and the second light-changing region 132 are smaller than the area of the light-transmitting region of the light-transmitting member 110, the light-changing member 130 can further include a third light-changing region 133, and of course, a fourth light-changing region, a fifth light-changing region, and so on.

[0098] By making the areas of the first light-changing area 131, the second light-changing area 132, and the third light-changing area 133 smaller than the light-transmitting area of the light-transmitting body 110, the first type of lighting effect, the second type of lighting effect, and the third type of lighting effect of the first light-changing area 131, the second light-changing area 132, and the third light-changing area 133 are all presented in the vehicle cabin.

[0099] As a specific application scenario, the front area of the car can present the first type of light-changing effect of the first light-changing area 131; and the rear area of the car can present the second type of light-changing effect of the second light-changing area 132; more specifically, the first light-changing area 131 can be configured to have a higher light transmittance, and to be configured with a visual effect of blue sky and white clouds, so that the driver in the front row can have a good driving state; the second light-changing area 132 can be configured to have a lower light transmittance, and to be configured with visual effects such as a quiet starry sky or dark scenery, so that the passengers in the rear row can have a more comfortable riding experience.

[0100] Alternatively, the rear seats retain the aforementioned design, while the front area displays both the first and third dimming effects. The driver's seat is provided with the first dimming effect, which boasts higher light transmittance and a visual effect of blue sky and white clouds. The front passenger seat is provided with the third dimming effect, e.g., a visual effect between the rear and driver's seats. Of course, depending on the application scenario, more groups of dimming zones can be combined to create personalized dimming effects within the vehicle. For example, a quiet, restful dimming effect can be provided for all passengers except the driver. Another example is providing dimming effects with different cartoon patterns for children in different seats in the rear.

[0101] The boundary between the first light-changing area 131 and the second light-changing area 132 is at least partially angled to the direction of movement of the light modulator 130 relative to the light-transmitting body 110. For example, the boundary between the first light-changing area 131 and the second light-changing area 132 is at least partially perpendicular to the direction of movement of the light modulator 130 relative to the light-transmitting body 110. Therefore, when the light modulator 130 moves relative to the light-transmitting body 110, the boundary between the first light modulator 130 and the second light modulator 130 moves accordingly, providing the user with clear feedback on the adjustment of the light-changing effect.

[0102] As a specific solution, the first light-changing area 131 and the second light-changing area 132 have different light transmittance, color, thickness, pattern, thickness; or are composed of different materials.

[0103] The light-changing effect of the present application includes the change of the light-transmitting effect and also includes the pattern displayed by the light-changing body 130 on the interior of the vehicle. At this time, it is equivalent to the light-changing body 130 completely shielding the light passing through the light-transmitting body 110, which is also one of the light-changing effects of the present application.

[0104] As a specific solution, in order to achieve a light-changing effect and to adjust the heat brought by the light, the first light-changing area 131 and the second light-changing area 132 have different thermal conductivities.

[0105] As a specific plan, refer to Figure 1 、 Figure 2 and Figure 3 As shown, the roof skylight 100 also includes an inner lining 120. The inner lining 120 is arranged on the inner side of the light-changing body 130, that is, between the light-changing body 130 and the vehicle compartment space. Specifically, the inner lining 120 is arranged on the side of the light-changing body 130 away from the light-transmitting body 110, so that a space for accommodating the light-changing body 130 is formed between the inner lining 120 and the light-transmitting body 110. The function of the inner lining 120 is to cover and protect the light-changing body 130 from the inner side of the vehicle compartment. In order to achieve a variety of light-changing effects, the inner lining 120 can allow light passing through the light-changing body 130 to pass through. However, this does not mean that the inner lining 120 is completely transparent, but that the inner lining 120 can at least partially allow light to pass through. Of course, the inner lining 120 itself can also have corresponding light-changing effects, such as filtering, absorbing, reflecting, etc. of light. Similarly, the light-transmitting body 110 also has a light-changing effect relative to the light source. In other words, the light-transmitting body 110 is equivalent to the incident mirror of the light-changing body 130, and the lining body 120 is equivalent to the output mirror of the light-changing body 130. They can respectively change the incident and output light to change the different light-changing areas of the light-changing body 130 and ultimately act on the lighting effect of the vehicle compartment.

[0106] As some extensions of this application, refer to Figures 1 to 5 As shown, the light-transmitting body 110 or the lining body 120 can be provided with partitions similar to the light-changing area of the light-changing body 130, which are defined as incident partitions and exit partitions, respectively. More specifically, the difference between the incident partitions can be color, transmittance, etc. Similarly, the difference between the exit partitions can also be color, transmittance, etc.

[0107] In this way, more light-changing effects can be achieved in the vehicle cabin through the combination of incident partitions, exit partitions and the variable light-changing areas between them.

[0108] Based on this design concept, multiple layers of light modifiers 130 can be configured to achieve more flexible light-modifying effects. Specifically, the roof screen 100 includes multiple light modifiers 130. These light modifiers 130 can be arranged in two ways: one is to stack the light modifiers 130, i.e., at different positions in the vertical direction; the other is to arrange the light modifiers 130 side by side (horizontally), i.e., at different positions in the left-right or front-back directions.

[0109] As a more specific solution, when the light modulators 130 are arranged in a stacked manner, in order to separate the two light modulators 130 or adjust the light between the two light modulators 130, refer to Figure 7 As shown, the roof skylight 100 also includes: an intermediate body. The intermediate body is arranged between the two light-changing bodies 130. As a further solution, the light-changing body 130 can be constructed as a flexible body that can be rolled up. Due to its flexibility, the light-changing body 130 will fall down to a certain extent due to its own weight. When a single-layer light-changing body 130 is used, the light-changing body 130 can be prevented from falling down by limiting the space of the light-changing body 130 by the interlayer formed by the light-transmitting body 110 and the lining body 120. When there are multiple layers of light-changing bodies 130, more interlayers are formed by using an intermediate body between the light-transmitting body 110 and the lining body 120 to prevent the light-changing bodies 130 of each layer from falling down. In addition, as mentioned above, the intermediate body can also be regarded as an intermediate lens, especially in combination with different light-changing areas of the light-changing body 130 to achieve more light-changing effects.

[0110] As a more specific solution, one of the translucent body 110, the lining body 120, and the intermediate body can be made of glass. Of course, other translucent materials with similar glass properties can also be used. The glass referred to here can be pure glass, coated glass, etc. In this case, the translucent body 110 is the outer layer of glass in the roof skylight 100, and the lining body 120 is the inner layer of glass in the roof skylight 100.

[0111] As a more specific solution, in order to achieve more light-changing effects, the translucent body 110, the lining body 120, and the intermediate body 170 can be configured as electrochromic glass. This allows the translucent body 110, the lining body 120, and the intermediate body 170 to change color in whole or in part through electrical control, further enhancing the light-changing effect.

[0112] When multiple light modifiers 130 are arranged side by side, Figure 8 and Figure 9 As shown, more combinations of color-changing effects can be provided in the vehicle cabin space, thereby enabling each seat to achieve personalized color-changing effects.

[0113] Reference Figures 1 to 6 As shown, in order to achieve the installation of various parts of the roof skylight 100, the roof skylight 100 of the present application also includes a bracket 140, which is mainly used to support the lining body 120, and the light-transmitting body 110 is directly supported by the roof of the vehicle 10.

[0114] Reference Figures 1 to 6As shown, to drive the light-changing element 130, the roof screen 100 further includes a rotating mechanism 150. The rotating mechanism 150 is used to drive the light-changing element 130 to move and / or retract. Specifically, the rotating mechanism 150 includes a front reel 151, a rear reel 152, a drive motor 153, a clutch 155, a damper 154, a driving member 156, and a driven member 157.

[0115] Reference Figure 3 and Figure 4 As shown, the front reel 151 is used to reel in a portion of the light-changing element 130, while the rear reel 152 is used to reel in another portion of the light-changing element 130. The front reel 151 and the rear reel 152 are spaced a predetermined distance apart to allow the first light-changing area 131 or the second light-changing area 132 to unfold between the front reel 151 and the rear reel 152. A drive motor 153 is connected to the front reel 151 or the rear reel 152 to drive the rotation of the front reel 151 or the rear reel 152. Specifically, two drive motors 153 are provided to drive the front reel 151 and the rear reel 152, respectively. The motor shaft of the driving motor 153 is connected to the active member 156, and the front side scroll 151 and the rear side scroll 152 are respectively connected to the driven member 157. A transmission connection is formed between the active member 156 and the driven member 157, so that when the driving motor 153 rotates, the front side scroll 151 and the rear side scroll 152 are driven to rotate.

[0116] The damper 154 is used to provide a certain amount of damping to the rotation of the front reel 151 and the rear reel 152 , thereby ensuring the stability of their rotation.

[0117] Since the front reel 151 and the rear reel 152 rotate at the same angular velocity due to the traction of the connector, and the different thicknesses of the wound connectors result in the same linear velocity, this can easily cause the connectors to pile up or stretch excessively. To solve this problem, a clutch 155 is provided between the motor shaft and the active member 156, so that the motor shaft can only achieve one-way transmission to the active member 156, and the active member 156 cannot drag the motor shaft in the reverse direction. That is, when the drive motor 153 stops, the front reel 151 and the rear reel 152 are in a free rotation state without being restricted by the drive motor 153.

[0118] Alternatively, the clutch 155 may be an electromagnetic clutch 155, which can be controlled by an electronic control system. When necessary, the clutch 155 is engaged, so that the motor shaft and the active member 156 form a fixed connection, thereby driving the corresponding front reel 151 or rear reel 152 to rotate. When the other drive motor 153 is running, the clutch 155 is disengaged, so that the motor shaft and the active member 156 are disengaged.

[0119] As an extended solution, a one-way coupling can also be used to connect the motor shaft and the active member 156 to achieve the solution.

[0120] As an extended solution, a flexible shaft or the like may be used to drive the front reel 151 or the rear reel 152 by using only one drive motor 153 .

[0121] Reference Figure 1 and Figure 10 As shown, considering that the rotating mechanism 150 is a power source for driving the light-changing body 130 to move and / or retract, it is active and its service life and performance are easily reduced when it is affected by external environmental factors such as dust and moisture. In order to protect the rotating mechanism 150, the roof skylight 100 also includes a protective cover 160. Among them, a receiving groove 160a is formed for accommodating the rotating mechanism 150, and the protective cover 160 and the light-changing body 130 are arranged on the same side of the light-transmitting body 110. Therefore, this solution can make full use of the space on the side of the light-transmitting body 110 close to the light-changing body 130 to configure the protective cover 160, and use the protective cover 160 to configure the rotating mechanism 150 in the relatively closed receiving groove 160a, thereby reducing the impact of external environmental factors on the performance of the rotating mechanism 150.

[0122] In a specific solution, the protective cover 160 is used as a dust cover, for example, covering the outside of at least a portion of the rotating mechanism 150 to reduce the impact of external dust on the stability of the rotating mechanism 150.

[0123] In a specific solution, the receiving groove 160a formed by the protective cover 160 can form an opening on the side close to the light-transmitting body 110. In the process of assembling the protective cover 160 onto the light-transmitting body 110, the light-transmitting body 110, for example, adopts a method of contacting with the solid wall surface of the protective cover 160, so that the light-transmitting body 110 closes the side of the receiving groove 160a where the opening is formed, that is, the rotating mechanism 150 is closed and arranged between the light-transmitting body 110 and the protective cover 160. Compared with the method of completely utilizing the protective cover 160 to seal and protect the rotating mechanism 150, this method reduces the solid wall thickness of the protective cover 160, thereby reducing the overall space occupied by the roof skylight 100, thereby facilitating its integration into the vehicle 10.

[0124] To enable the rotation mechanism 150 to drive the light modulator 130 to move and / or retract, the protective cover 160 is formed with a relief groove 160b that communicates with the accommodating groove 160a. Specifically, the relief groove 160b is used to allow the light modulator 130 to pass through. The relief groove 160b is connected to the side of the accommodating groove 160a near the light-transmitting body 110, allowing the light modulator 130 to enter and exit the relief groove 160b. This relief groove 160b then connects to the rotation mechanism 150 within the accommodating groove 160a, allowing the rotation mechanism 150 to drive the light modulator 130 to move and / or retract.

[0125] In some embodiments, the protective cover 160 includes a first shell 161 and a second shell 162. The first shell 161 is fixedly mounted on the side of the light-transmitting member 110 near the light-modulating member 130. This allows the protective cover 160 to be integrated with the light-transmitting member. The fixing methods for the first shell 161 and the protective cover 160 include, for example, threaded connection, snap-fit connection, pin-to-pinhole fastening, gluing, etc., which are not limited in this application. In a specific embodiment, the avoidance groove 160b can be formed on the first shell 161.

[0126] The second housing 162 and the first housing 161 together form a receiving groove 160a. This configuration allows, after the first housing 161 is integrated into the light-transmitting member, the rotating mechanism 150 to be secured to the first housing 161 or the second housing 162 through threaded connections, snap-fit connections, pin-to-pinhole fastening, gluing, or other methods. The first housing 161 and the second housing 162 are then fixedly connected, thereby placing at least a portion of the rotating mechanism within the receiving groove 160a. During maintenance, the receiving groove 160a can be opened to the outside by disassembling the first and second housings 161, 162, allowing inspection of the rotating mechanism 150 without having to remove the protective cover 160, the rotating mechanism 150, and so on from the light-transmitting member, thereby facilitating maintenance work.

[0127] Although the above description describes that the rotating mechanism 150 is installed on the protective cover 160 and then integrated with the translucent body 110, in an optional solution, the rotating mechanism 150 can also be fixedly set on the translucent body 110. In this case, the protective cover 160 can still be used to provide protection for the rotating mechanism 150.

[0128] In some embodiments, the protective cover 160 further includes a sealing layer (not shown). The sealing layer is disposed between the first shell 161 and the second shell 162 to seal the receiving groove 160a. Because the receiving groove 160a is formed by the first shell 161 and the second shell 162, the sealing layer improves the sealing between the first shell 161 and the second shell 162, ensuring effective protection for the rotating mechanism 150.

[0129] Considering the sealing performance between the first shell 161 and the light-transmitting body 110, a sealing layer may be disposed between the first shell 161 and the light-transmitting body 110 to seal the receiving groove 160a. Figure 10As shown, a sealing groove 161a is provided on a side of the first housing 161 near the light-transmitting body 110, so that the sealing layer is positioned and disposed within the sealing groove 161a. Specifically, when the first housing 161 and the light-transmitting body 110 are combined, the foam / sealing strip fills the sealing groove 161a to at least partially surround the periphery of the receiving groove 160a, so that the sealing layer abuts the first housing 161 and the light-transmitting body 110, thereby sealing the contact area between the first housing 161 and the light-transmitting body 110.

[0130] In a specific embodiment, the sealing layer can be configured as, for example, a foam glue / sealing strip disposed between the first shell 161 and the second shell 162. The sealing strip is made of, for example, a deformable material such as rubber. When the first shell 161 and the second shell 162 are fixed together by threaded connection, snap fastening, pin-to-pinhole fixing, gluing, or the like, a foam glue and / or sealing strip is disposed between the first shell 161 and the second shell 162. The foam glue and / or sealing strip is brought into close contact with the first shell 161 and the second shell 162 by the compression of the first shell 161 and the second shell 162, thereby achieving sealing of the receiving groove 160a.

[0131] In some embodiments, reference Figure 11 As shown, the roof screen 100 further includes a guide rail 180. The guide rail 180 is used to support the light-changing element 130. Specifically, the guide rail 180 is fixedly mounted on the light-transmitting element 110 or the inner lining 120. The guide rail 180 is located on the side of the light-transmitting element 110 that is closest to the light-changing element 130 and between the light-transmitting element 110 and the inner lining 120. The guide rail 180 supports the light-changing element 130, ensuring that the light-changing element 130 is stably mounted between the light-transmitting element 110 and the inner lining 120.

[0132] In some embodiments, a hollow cavity 100 a is formed between the light-transmitting body 110 and the lining body 120 , and the guide rail 180 is disposed in the hollow cavity 100 a .

[0133] In some embodiments, the light modulator 130 and the guide rail 180 are at least partially engaged to form a sliding connection between the light modulator and the guide rail 180 , thereby limiting the movement direction of the light modulator 130 by the guide rail 180 to ensure smooth movement.

[0134] Regarding the specific solution of connecting the guide rail 180 and the light-changing body 130 to support the light-changing body 130, for example, the light-changing body 130 can be configured as a membrane, cloth, etc. with flexible deformation ability, so that the light-changing body 130 can move under the drive of the front scroll 151 or the rear scroll 152. The two sides of the light-changing body 130 can fall on the surfaces of the two guide rails 180 respectively, so that the guide rails 180 can support the light-changing body 130 and prevent it from drooping when it moves. Furthermore, the guide rail 180 can be extended along the moving direction of the light-changing body 130 relative to the light-transmitting body 110, and a protrusion can be provided on the side of the light-changing body 130, so that the protrusion and the guide rail form a sliding connection in an interlocking form, so that the guide rail 180 can be used to guide the moving direction of the light-changing body 130. According to the second aspect of the present application, with reference to Figure 12 As shown, a vehicle 10 is provided, which includes the above-mentioned roof skylight 100. The vehicle 10 has all the beneficial effects of the above-mentioned roof skylight 100, which will not be described in detail in this application.

[0135] The vehicle 10 may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and this application does not make any specific limitation thereto.
