[0002] The automobile sunroof is a ventilation and lighting device installed on the top of the automobile, which realizes ventilation, lighting, air exchange and other functions by opening or closing, and improves the comfort of the vehicle environment. The sunroof glass is the core component of the sunroof, which allows natural light to enter the vehicle through transparent or semi-transparent design, reduces the dependence on the vehicle light during the day, improves the space permeability, and reduces the external wind noise, rain noise and other noises into the vehicle, and improves the quietness.

[0003] In the prior art, the automobile sunroof assembly usually includes a frame, a sunroof and a driving mechanism, and two sides inside the frame are generally provided with sliding rails to facilitate the movement of the sunroof. However, after the sliding rails are installed, the space on both sides of the frame will be occupied, so that the remaining space is greatly reduced. When it rains heavily or when the car is washed, the water volume is too large, the remaining space on both sides of the frame is narrow, and the water cannot be drained in time, which causes the water to overflow and seep into the vehicle through the gap, resulting in the ceiling being damp, the seat being wet, and the growth of mold and the aging of the interior decoration.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In use, as the water level rises, the float pushes the top plate upwards, causing the gravity ball to be lifted upwards. This lifts one side of the rotating plate upwards while forcing the other side to rotate downwards, pushing the hook plate downwards and generating a lateral thrust on the fixed plate, pulling the sealing block out of the expansion hole. At this time, water from both sides enters the slide rail body, effectively adding a "temporary water storage area," increasing the water capacity on both sides inside the sunroof bottom frame, and preventing direct overflow due to excessive water volume. Additionally, water is discharged through the water guide plate and outlet pipe, expanding the drainage path, reducing the drainage pressure of a single channel, accelerating the drainage speed, and reducing the risk of water overflow.

[0017] 2. In use, as the float and top plate descend, the gravity ball pulls one side of the rotating plate downwards and the other side upwards, causing the hook plate to move upwards. This reduces the thrust on the fixed plate, and the return force of the reset spring pushes the sealing plate in the opposite direction, pushing the sealing block into the expansion hole. The accumulated water is then discharged normally through the original drainage channel. The sealing block guides the accumulated water to concentrate along the original water guide channel and the first drainage pipe, preventing water dispersion and stagnation due to a longer flow path, which would reduce drainage speed. With the cooperation of the sealing assembly and the track assembly, dynamic adaptation of "efficient drainage for small volumes and expanded water storage for large volumes" is achieved. Through buoyancy, "automatic switching" is realized, eliminating the need for electronic control and reducing energy consumption.

[0018] 3. When using this invention, a positive voltage is applied to the dimming glass panel. Ions in the ion conductor layer migrate from the ion storage layer to the electrochromic layer, undergoing a reduction reaction, resulting in a darker color and a significant decrease in light transmittance. When a reverse voltage is applied, ions migrate back from the electrochromic layer to the ion storage layer, the color fades, and the light transmittance recovers. By adjusting the voltage, stepless dimming from transparent to completely light-blocking can be achieved. The dimming glass panel, through a multi-layer composite structure, constitutes electrochromic dimming glass and combines sun protection and isolation functions to achieve an integrated "dimming + sun protection + heat insulation" function, balancing protection efficiency and protection of the multi-layer composite structure.

[0023] In this embodiment, during use, two track components 2 and two sealing components 3 are provided. The two sealing components 3 are respectively installed inside the two track components 2. The two track components 2 are respectively located at the bottom of both sides of the glass frame 4. The two slide rail bodies 201 are respectively installed on both sides inside the bottom frame 1 of the sunroof. Figure 1As shown. When the water on top of the dimming glass panel 5 slides into the skylight bottom frame 1, it will be discharged through the first drain pipe 7 and the second drain pipe 8. The float bar 323 rests on the top rod 325. When the water volume on both sides inside the skylight bottom frame 1 gradually increases, the float bar 323 will be affected by buoyancy, float on the water surface, and gradually rise from the top of the top rod 325. As the water level rises, the float 323 pushes the top plate 324 upward, gradually bringing it into contact with the gravity ball 310 and generating an upward thrust on it. With the coordinated movement of the connector 309, support rod 308, sliding groove 305, and support groove 306, an upward thrust is generated on one side of the rotating plate 304, causing one side of the rotating plate 304 to gradually rise. Under the limitation of the center rod 206, the other side of the rotating plate 304 is forced to move downward. With the coordinated movement of the connector 309, support rod 308, sliding groove 305, and support groove 306, the hook plate 311 is pushed downward, simultaneously causing the support block 316 to move downward, compressing the telescopic rod 317 and the support spring 318. As the hook plate 311 moves downward, its inclined surface a gradually contacts the interior of the fixed plate 303, generating a lateral thrust on the fixed plate 303. This causes the fixed plate 303 to move to one side, simultaneously driving the slider 314 to slide in the guide rail 315, further moving the sealing plate 301 and gradually pulling the sealing block 302 out of the corresponding expansion hole 204. When the contact surface between the fixed plate 303 and the hook plate 311 changes from inclined surface a to vertical surface b, the rotating plate 304 is limited by the rotating hole 205 and cannot continue to rotate. At this time, the sealing block 302 is completely removed from the expansion hole 204, and the float 323 is located below the rotating hole 205. At the same time, water on both sides of the interior of the sunroof bottom frame 1 enters the slide rail body 201 through the connected expansion hole 204, which is equivalent to adding a "temporary water storage area," increasing the water capacity on both sides of the interior of the sunroof bottom frame 1, distributing the drainage pressure of the narrow space on both sides, and preventing the instantaneous water volume from overflowing directly. Next, the water distributed in the slide rail body 201 flows into the water guide plate 202 and is finally discharged through the outlet pipe 203. The accumulated water changes from a single drainage path to two different drainage paths: the original water guide channel path + the expanded drainage path. This reduces the drainage pressure of a single channel and speeds up the drainage. Especially when a pipe in the first drainage pipe 7 is partially blocked, the diversion can slow down the rise of accumulated water and reduce the risk of water overflow. With the cooperation of the sealing component 3 and the track component 2, the two sides of the space inside the sunroof bottom frame 1 can achieve dynamic expansion of drainage, significantly increasing the water capacity and enriching the drainage path. This reduces the drainage pressure of the original drainage path and helps improve the efficiency of water discharge. Furthermore, without changing the original sliding function of the slide rail body 201, the internal idle space is utilized for expansion, avoiding large-scale modifications to the overall structure of the sunroof component.This solution addresses the issue that after the sliding rails are installed in the car sunroof assembly, the remaining space on both sides of the frame becomes significantly smaller. In special circumstances, if too much water slides into the frame from the top of the sunroof, the narrow space on both sides of the frame will not drain properly, causing water to overflow and seep into the car through gaps, resulting in a damp roof and mold growth.

[0024] Furthermore, as the water level on both sides inside the bottom frame 1 of the skylight gradually decreases, the float bar 323 and the top plate 324 gradually descend, and the pushing force on the gravity ball 310 gradually decreases. Under the gravity of the gravity ball 310, one side of the rotating plate 304 rotates downward to reset, and the other side of the rotating plate 304 rotates upward to reset, causing the hook plate 311 to move upward. Its contact surface with the fixed plate 303 moves from surface b to surface a, and finally to the bottom of the hook plate 311. Figure 10 As shown, as the hook plate 311 moves upward, the thrust on the fixed plate 303 decreases, and the compressed return spring 321 gradually rebounds, pushing the sealing plate 301 to move in the opposite direction, causing the sealing block 302 to move back into the expansion hole 204 and seal the expansion hole 204. At this time, the water accumulated on both sides inside the sunroof bottom frame 1 is discharged normally through the original drainage channel, without the need to use the expansion space of the slide rail body 201. The sealing of the sealing block 302 can guide the accumulated water to concentrate and discharge along the original water guide channel and the first drainage pipe 7, avoiding water flow dispersion, longer flow path and stagnation, which would lead to a decrease in drainage speed. With the cooperation of the sealing component 3 and the track component 2, dynamic adaptation of "efficient drainage of small water volume and expansion storage of large water volume" is achieved. Through water buoyancy, "automatic opening and closing" is achieved without electronic control, reducing power consumption.

[0025] Example 2: Figures 1-3 As shown, a track assembly 2 and a sealing assembly 3 are installed inside the bottom frame 1 of the sunroof. A glass frame 4 is installed on the top of the track assembly 2. A dimming glass panel 5 is fixedly installed inside the glass frame 4. The dimming glass panel 5 includes an outer protective glass 501. An ultraviolet reflective layer 502 is installed at the bottom of the outer protective glass 501. An infrared reflective layer 503 is installed at the bottom of the ultraviolet reflective layer 502. A first transparent conductive layer 504 is installed at the bottom of the infrared reflective layer 503. An electrochromic layer 505 is installed at the bottom of the first transparent conductive layer 504. An ion conductor layer 506 is installed at the bottom of the electrochromic layer 505. An ion storage layer 507 is installed at the bottom of the ion conductor layer 506. A second transparent conductive layer 508 is installed at the bottom of the ion storage layer 507. An inner supporting glass 509 is installed at the bottom of the second transparent conductive layer 508. A sealing layer 510 is installed at the bottom of the inner supporting glass 509.

[0026] In this embodiment, when no voltage is applied to the dimming glass panel 5, it is in a transparent state, allowing a large amount of light to pass through. When a positive voltage is applied to the dimming glass panel 5, ions in the ion conductor layer 506 migrate from the ion storage layer 507 to the electrochromic layer 505 under the influence of the electric field, undergoing a reduction reaction. This significantly enhances the absorption of visible light and drastically reduces the light transmittance. When a reverse voltage is applied, ions migrate back from the electrochromic layer 505 to the ion storage layer 507, causing the dimming glass panel 5 to fade and the light transmittance to increase. By adjusting the voltage, the amount of ion migration can be controlled, thereby precisely controlling the light absorption capacity of the electrochromic layer 505 and achieving stepless dimming from transparent to completely opaque.

[0027] Furthermore, the dimming glass panel 5 incorporates an ultraviolet reflective layer 502 and an infrared reflective layer 503. The ultraviolet reflective layer 502 reflects ultraviolet rays, preventing them from penetrating the glass and entering the vehicle interior, thus avoiding skin damage and interior aging. The infrared reflective layer 503 reflects infrared rays, reducing their conversion into heat that enters the vehicle interior and lowering the air conditioning load. The dimming glass panel 5, through its multi-layered composite structure, forms an electrochromic dimming glass, combined with sun protection and insulation functions, achieving an integrated "dimming + sun protection + heat insulation" system, balancing protective efficiency with the protection of the multi-layered composite structure.

[0028] The overall effect and working principle of the mechanism are as follows: When the water volume in both sides of the bottom frame 1 of the skylight gradually increases, the float bar 323 pushes the top plate 324 to move upward, generating an upward thrust on the gravity ball 310. With the coordinated movement of the connector 309, support rod 308, sliding groove 305 and support groove 306, one side of the rotating plate 304 is gradually pushed upward, while the other side is forced to move downward, thereby pushing the hook plate 311 downward and simultaneously driving the support block 316 downward, squeezing the telescopic rod 317 and support spring 318. As the hook plate 311 moves downward, its inclined surface a gradually contacts the inside of the fixed plate 303, generating a lateral thrust on the fixed plate 303, thereby causing the fixed plate 303 to move to one side, further driving the sealing plate 301 to move, and gradually pulling the sealing block 302 out of the corresponding expansion hole 204. When the contact surface between the fixed plate 303 and the hook plate 311 changes from the inclined surface a to the vertical surface b, the rotating plate 304 is limited by the rotating hole 205 and cannot continue to rotate. At this time, the sealing block 302 completely moves out of the expansion hole 204, and the float 323 is located below the rotating hole 205. At the same time, water on both sides inside the sunroof bottom frame 1 enters the slide rail body 201 through the connected expansion hole 204, which is equivalent to adding a "temporary water storage area", increasing the water capacity on both sides inside the sunroof bottom frame 1, distributing the drainage pressure of the narrow space on both sides, and preventing the instantaneous water volume from overflowing directly. Then, the water distributed in the slide rail body 201 flows into the water guide plate 202, and finally is discharged through the water outlet pipe 203. The accumulated water changes from the original single drainage path to two different drainage paths, namely the original water guide channel path + the expansion drainage path, reducing the drainage pressure of the single channel and speeding up the drainage speed. As the water level on both sides of the skylight bottom frame 1 gradually decreases, the float bar 323 and top plate 324 gradually descend, reducing the pushing force on the gravity ball 310. Under the gravity of the gravity ball 310, one side of the rotating plate 304 rotates downwards to reset, while the other side rotates upwards to reset. This causes the hook plate 311 to move upwards, reducing the pushing force on the fixed plate 303. The compressed reset spring 321 gradually rebounds, pushing the sealing plate 301 to move in the opposite direction, causing the sealing block 302 to move back into the expansion hole 204, sealing the expansion hole 204. At this time, the accumulated water on both sides of the skylight bottom frame 1 is discharged normally through the original drainage channel, without the need to use the expansion space of the slide rail body 201. When no voltage is applied to the dimming glass panel 5, it is in a transparent state, allowing a large amount of light to pass through. When a positive voltage is applied to the dimming glass panel 5, ions in the ion conductor layer 506 migrate from the ion storage layer 507 to the electrochromic layer 505 under the action of the electric field, undergoing a reduction reaction. This significantly enhances the absorption of visible light and greatly reduces the light transmittance.When a reverse voltage is applied, ions migrate from the electrochromic layer 505 back to the ion storage layer 507, the color fades, and the light transmittance increases. By adjusting the voltage, the amount of ion migration can be controlled, thereby precisely controlling the light absorption capacity of the electrochromic layer 505 and achieving stepless dimming from transparent to completely opaque.
