Description

[Technical Field]

[0001] The present invention relates to the technical field of vehicle sunroofs, and more particularly to an air intake structure for a vehicle sunroof and a touring car with a sunroof. [Background technology]

[0002] Existing touring cars are fitted with a sunroof comprising a base and an outer cover. A ventilation passage extends through the base, and the front end of the outer cover is hinged to the front end of the base. When the sunroof is open, the outer cover is rotated upward away from the base so that the ventilation passage connects the interior and exterior of the vehicle. The outer cover rotates until it approaches the base and covers the ventilation passage's air intake, at which point the sunroof is in a closed state. The touring car sunroof disclosed in prior patent CN205097897U has a ventilation passage's air intake that directly connects to the outside and no air intake grille, resulting in the following defects: On the one hand, dust and other foreign matter can easily enter the ventilation passage and the vehicle interior; and on the other hand, the airflow directly impinges on the air intake passage, easily damaging the sunroof's internal structure and reducing comfort due to airflow turbulence. To solve the above problems, prior patent US10858884B2 discloses a potentially driven electric curtain and / or its manufacturing method with improved coil strength, specifically disclosing a foldable air vent. An air intake grille is hinged between the outer cover and the base. The air intake grille is located behind the base and outside the air intake port of the ventilation passage. However, the installation structure of the air intake grille is complicated, making it difficult to remove and clean afterwards. Furthermore, conventional air intake grilles tend to loosen, causing shaking and noise. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE INVENTION In order to solve the problem of the conventional sunroof air intake grille of a touring car being difficult to remove, the present invention provides an air intake structure for a vehicle sunroof and a touring car with a sunroof. [Means for solving the problem]

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: An air intake structure for a vehicle sunroof, comprising a base, an outer cover, and an intake grille. The front end of the base and the front end of the outer cover are hingedly connected. A ventilation passage passes through the base. The intake grille is located below the rear end of the outer cover and is detachably connected to the outer cover. The intake grille is located outside the intake port of the ventilation passage, and when the outer cover cooperates with the base to cover the intake port, a relief gap is formed between the intake grille and the base. When the outer cover rotates away from the base to open the intake port, the outer cover moves the intake grille toward the base, and the relief gap is gradually narrowed, at which time airflow from outside the vehicle cabin flows into the vehicle cabin through the intake grille, the intake port, and the ventilation passage in that order.

[0005] A roller assembly is provided at one end of the intake grille near the base, the roller assembly including a roller wheel, and a rail is provided on the base, the rail being adapted to fit the rotation path of the intake grille so that the roller wheel always abuts against the rail during rotation of the intake grille.

[0006] The roller assembly further includes a rotating shaft and a connecting rod. The air intake grille is provided with a guide groove. One end of the connecting rod is slidably disposed within the guide groove, and the other end of the connecting rod is connected to the rotating shaft. The roller wheel is fitted onto the rotating shaft, and a spring is disposed between the end of the connecting rod remote from the rotating shaft and the guide groove.

[0007] The spring action keeps the roller wheels pressed against the rail, eliminating the gap that occurs when the outer lid opens and closes due to the unevenness of the rail. The roller assembly has a simple structure, is highly reliable, and is cleverly designed for smooth operation.

[0008] Furthermore, the opening angle of the outer cover is α, which is in the range of 0°<α≦10°, ensuring effective ventilation of the sunroof after the outer cover is opened, and ensuring the reliability, stability, safety and aesthetics of the sunroof.

[0009] Preferably, the air intake is provided with a sealing ring, and when the outer cover and the base cooperate to cover the air intake, the outer cover comes into contact with the sealing ring, ensuring a tight seal after the outer cover is closed and effectively preventing wind and water leakage through the sunroof.

[0010] Furthermore, the intake grille is removably connected to the outer cover by bolts, which has a simple and reliable structure, is easy to attach and detach, and is low in cost.

[0011] Furthermore, a plurality of support rods are fixed to the bottom of the outer cover, and the support rods are sequentially installed around the outer periphery of the intake grille, and the bolts sequentially connect the intake grille and the support rods, optimizing the intake grille mounting structure and improving the reliability and stability of the intake grille mounting.

[0012] A touring car with a sunroof includes any of the vehicle sunroof air intake structures, the base is provided on the top of the touring car, and both the outer cover and the air intake grille are exposed from the touring car.

[0013] Preferably, the vehicle sunroof further includes a lifting mechanism. The lifting mechanism rotates the outer cover upward to open the ventilation passage or downward to close the ventilation passage. The lifting mechanism includes an electric drive structure and a manual drive structure. The electric drive structure includes a screw, a first cantilever, a second cantilever, and a motor. The manual drive structure includes a gear set and a handle. The screw is horizontally mounted on the base along the width direction of the touring car and located rearward of the ventilation passage. The bottom end of the first cantilever is threaded onto the screw by a first slider, and the bottom end of the second cantilever is threaded onto the screw by a second slider. The top ends of the first cantilever and the second cantilever are both connected to the outer cover via holders, and the first cantilever and the second cantilever are arranged crosswise. The output end of the motor is connected to one end of the screw. The input end of the gear set is connected to the handle, and the output end of the gear set is connected to one end of the screw remote from the motor. As the screw rotates, the first cantilever and the second cantilever move toward or away from each other. If manual control of opening and closing the outer lid is required, particularly in the event of a power outage, simply rotate the handle manually inside the touring car, which then rotates the screw via the gear set. As the screw rotates, the first and second sliders slide along the screw, and when the first and second sliders slide toward or away from each other, the first and second cantilevers rotate the outer lid upward to open it, or downward to close it. The gear set provides stable power transmission and high transmission efficiency, which is significantly improved compared to the transmission efficiency of a flexible shaft, making manual operation easier and less labor-intensive.

[0014] Preferably, the vehicle sunroof further includes an upper assembly and a lower assembly, and the base, outer cover, and air intake grille constitute the upper assembly. The air intake grille is horizontally positioned when the outer cover closes the ventilation passage, and each grille hole is gradually inclined forward from bottom to top.

[0015] The lower assembly includes a lower sheet and a filter component. A ventilation passage extends through the lower sheet. The filter component includes a filter frame and a filter mounted in the filter frame. The filter frame is detachably connected to the lower sheet, and the filter is positioned within the ventilation passage.

[0016] The base and the lower sheet are respectively provided on the upper and lower sides of the top plate of the touring car, the bottom of the base forming a first cylindrical portion, the top of the filter frame forming a second cylindrical portion, and the first cylindrical portion and the second cylindrical portion being fitted together so as to be movable along the thickness direction of the top plate. When the outer cover opens the ventilation passage, the outside of the touring car, the intake grille, the ventilation passage, the filter, and the inside of the touring car are sequentially connected to each other.

[0017] When maintaining the filter component, the lower assembly is first removed, and then the filter component is removed from the lower assembly. This makes installation and removal very easy, facilitating daily maintenance, servicing, and cleaning of the filter. At the same time, the second cylindrical part of the filter frame is fitted to the first cylindrical part of the base and is movable along the thickness direction of the top plate, so it can be adapted to touring car top plates of different thicknesses. That is, the second cylindrical part of the filter frame and Bass The first cylindrical portion is moved along the thickness direction of the top plate to fit touring car top plates of different thicknesses, while the first cylindrical portion and the second cylindrical portion still maintain a fitted state to ensure airflow, thereby cleverly realizing both easy removal of the filter component and adaptability to touring car top plates of different thicknesses at the same time.

[0018] Furthermore, the inclination angle of the grille holes is β, and the value of β ranges from 30° to 60°. This ensures a smooth connection between the grille holes and the inside of the outer cover, ensuring no blockage during intake or exhaust, smoother airflow, and effectively increasing ventilation.

[0019] Furthermore, the cross-sectional area of ​​the grille holes is S, and the value of S ranges from 3.0 square centimeters to 3.6 square centimeters. The appropriate size of the grille holes is favorable for the passage of air, arranging the airflow and making it smoother and more comfortable. They also effectively filter out impurities and mosquitoes, and work together with the filter to achieve double-layer filtration, effectively preventing mosquitoes and ensuring clean, fresh filtered air. The air intake grille has a small viewing area, which is aesthetically pleasing.

[0020] Furthermore, the lower sheet is detachably connected to the top plate by a first screw, and the filter frame is detachably connected to the lower sheet by a second screw. To remove the lower assembly, the first screw is first removed, and to remove the filter component from the lower assembly, the second screw is further removed. This extremely easy installation and removal facilitates daily maintenance, upkeep, and cleaning of the filter.

[0021] Furthermore, a decorative cover is provided at the bottom of the lower sheet, and the first screw sequentially fastens the decorative cover, the lower sheet, and the top plate together. The decorative cover not only serves to protect and dustproof, but also to enhance the aesthetic appearance.

[0022] Furthermore, a pleated shade cloth is disposed within the decorative cover, and side air vents are provided on the sides of the decorative cover. When the pleated shade cloth is deployed, it blocks the ventilation passage, and the side air vents communicate with the ventilation passage and the interior of the touring car. After the pleated shade cloth is deployed, it increases the airflow volume of the side air vents, changes the airflow direction, and simultaneously conceals imperfections. The pleated shade cloth can be patterned to enhance its appearance. [Effects of the Invention]

[0023] 1. The air intake structure of the vehicle sunroof of the present invention has an air intake grille and an outer cover that are detachably connected, making it easy to attach and detach the air intake grille and remove it for maintenance such as cleaning, and the structural design is simple and ingenious, with relatively low cost.

[0024] 2. The air intake structure of the vehicle sunroof of the present invention has an ingenious roller assembly design, which has a simple structure, high reliability, and smooth operation. The roller wheel is constantly pressed against the rail, eliminating the gap that occurs when the outer cover opens and closes due to the unevenness of the rail. This effectively prevents the outer cover and the air intake grille from loosening or shaking, and prevents the generation of abnormal noise.

[0025] 3. In the case where the opening and closing of the outer cover needs to be manually controlled, especially in the case of a power outage, the vehicle sunroof air intake structure of the present invention can be operated by simply manually rotating a handle in a touring car, which in turn rotates a screw via a group of gears. As the screw rotates, the first and second sliders slide along the screw, and when the first and second sliders slide toward or away from each other, the first and second cantilevers rotate the outer cover upward to open it, or downward to close it. The gear group provides stable power transmission and high transmission efficiency, which is significantly improved compared to that of a flexible shaft, making manual operation easier and less labor-intensive.

[0026] 4. In the touring car sunroof of the present invention, the lower assembly is first removed, and then the filter component is removed from the lower assembly. This makes installation and removal very easy, facilitating daily maintenance, repair, and cleaning of the filter. At the same time, the second cylindrical part of the filter frame is base The filter frame is fitted to the first cylindrical portion of the top plate and is movable along the thickness direction of the top plate, so that it can be adapted to touring car top plates of different thicknesses. Bass The first cylindrical portion is moved along the thickness direction of the top plate to fit touring car top plates of different thicknesses, while the first cylindrical portion and the second cylindrical portion still maintain a fitted state to ensure airflow, thereby cleverly realizing both easy removal of the filter component and adaptability to touring car top plates of different thicknesses at the same time.

[0027] 5. The sunroof for a touring car of the present invention has an outer cover BassThe outer cover rotates away from the cover to open the ventilation passage, and simultaneously moves the air intake grille until the outer cover reaches the set angle, sequentially connecting the exterior of the touring car, the air intake grille, the ventilation passage, the filter, and the interior of the touring car. Airflow from the exterior of the touring car passes through the air intake grille, ventilation passage, and filter, and then flows into the interior of the touring car. Airflow from the interior of the touring car passes through the filter, ventilation passage, and air intake grille, and then flows out of the touring car, achieving ventilation. The grille holes are gradually tilted forward from bottom to top, smoothly connecting with the interior of the outer cover. This allows for uninterrupted airflow during both intake and exhaust, resulting in smoother airflow and effectively increasing ventilation. The appropriate size of the grille holes facilitates airflow passage, streamlining the airflow and making it smoother and more comfortable. It also effectively filters out impurities and mosquitoes, and the small visible area of ​​the air intake grille contributes to a more aesthetically pleasing appearance.

[0028] 6. In the touring car sunroof of the present invention, the air intake grille can filter foreign objects, mosquitoes, etc., and cooperates with the filter to achieve double filtration, effectively preventing mosquitoes, keeping the filtered air clean and fresh and effectively preventing foreign objects from entering the touring car sunroof and preventing damage to the touring car sunroof. The sunroof can also be used after removing the filter components, and the touring car sunroof can still be used normally, especially when the filter is removed for cleaning and maintenance, and the air intake grille's filtering function against foreign objects, mosquitoes, etc., meets the basic requirements for use.

The roller assembly 9 has a simple structure, is highly reliable, has an ingenious design, and operates smoothly.

[0034] In order to ensure airtightness after the outer cover 2 is closed and effectively prevent wind and water leakage from the sunroof, in this embodiment, as shown in FIG. 5, a seal ring 7 is provided on the air intake 1-2, and when the outer cover 2 and the base 1 cooperate to cover the air intake 1-2, the outer cover 2 comes into contact with the seal ring 7.

[0035] As shown in Figures 4, 9, and 10, in this embodiment, the vehicle sunroof further includes a lifting mechanism 10. The lifting mechanism 10 is used to rotate the outer cover 2 upward to open or downward to close the ventilation passage 1-1. In this embodiment, the opening angle of the outer cover 2 is α, which is in the range of 0°<α≦10°. This ensures effective ventilation through the sunroof after the outer cover 2 is opened, while also ensuring the reliability, stability, safety, and aesthetics of the sunroof. The lifting mechanism 10 includes an electric drive structure 10-1 and a manual drive structure 10-2. The electric drive structure 10-1 includes a screw 10-1-1, a first cantilever 10-1-2, a second cantilever 10-1-3, and a motor 10-1-4.

When the screw 10-1-1 rotates, the first cantilever 10-1-2 and the second cantilever 10-1-3 move toward or away from each other.

[0036] The touring car with a sunroof includes the air intake structure of the vehicle sunroof, the base 1 is provided on the top of the touring car, and the outer cover 2 and the air intake grille 3 are both exposed from the touring car.

[0037] The operating principle is as follows: The opening process of the air intake structure for the vehicle sunroof is as follows: First, the outer cover 2 rotates away from the base 1 to open the air intake 1-2. At the same time, the outer cover 2 moves the air intake grill 3 closer to the base 1, and the escape gap 4 gradually narrows. While the air intake grill 3 rotates, the roller wheel 9-1 always abuts against the rail 1-3 due to the action of the spring 9-4. After the outer cover 2 is fixed at a certain opening angle, the roller wheel 9-1 provides auxiliary support for the outer cover 2. At this time, the air intake 1-2 is connected to the outside of the vehicle cabin via the air intake grill 3, and the airflow outside the vehicle cabin flows into the vehicle cabin via the air intake grill 3, the air intake 1-2, and the ventilation passage 1-1.

[0038] The closing process of the vehicle sunroof air intake structure is as follows: First, the outer cover 2 is rotated so that it approaches the base 1, and at the same time, the outer cover 2 moves the air intake grill 3 away from the base 1, gradually forming an escape gap 4 between the air intake grill 3 and the base 1.As the air intake grill 3 rotates, the roller wheel 9-1 is always in contact with the rail 1-3 due to the action of the spring 9-4, and the roller wheel 9-1 continues to provide auxiliary support for the outer cover 2 until the outer cover 2 covers the air intake port 1-2 and contacts the seal ring 7 to seal it.

[0039] The removal process of the vehicle sunroof air intake structure is as follows: The intake grill 3 can be removed simply by removing a plurality of screws between the intake grill 3 and the support rod 8, making it easy to attach and detach the intake grill 3 and to remove the intake grill 3 for maintenance such as cleaning.

[0040] [Example 2] As shown in Figures 12 to 21, this embodiment differs from the first embodiment in that the vehicle sunroof includes an upper assembly 11 and a lower assembly 12, as shown in Figures 14, 15, 17, and 18. The base 1, outer cover 2, and air intake grille 3 constitute the upper assembly 11. The air intake grille 3 is horizontally positioned when the outer cover 2 closes the ventilation passage 1-1, and each grill hole 3-3 is gradually inclined forward from bottom to top. As shown in Figures 14 and 15, the lower assembly 12 includes a lower sheet 12-1 and a filter component 12-2. The ventilation passage 1-1 penetrates the lower sheet 12-1. The filter component 12-2 includes a filter frame 12-21 and a filter 12-22 mounted on the filter frame 12-21. The filter frame 12-21 is detachably connected to the lower sheet 12-1, and the filter 12-22 is positioned within the ventilation passage 1-1. 13, 14, 19, and 21, the base 1 and lower sheet 12-1 are respectively provided on the upper and lower sides of the top plate 13 of the touring car, the bottom of the base 1 forms a first cylindrical portion 1-4, and the top of the filter frame 12-21 forms a second cylindrical portion 12-211, and the first cylindrical portion 1-4 and the second cylindrical portion 12-211 are fitted so as to be movable along the thickness direction of the top plate 13. When the outer cover 2 opens the ventilation passage 1-1, the outside of the touring car, the air intake grille 3, the ventilation passage 1-1, the filter 12-22, and the inside of the touring car are sequentially connected.

[0041] Furthermore, in this embodiment, as shown in FIG. 20, the inclination angle of the grille holes 3-3 is β, which ranges from 30° to 60° and can be selected as 45°. This ensures a smooth connection between the grille holes 3-3 and the inside of the outer cover 2, ensuring unobstructed airflow during both intake and exhaust, smoother airflow, and effectively increasing ventilation. The cross-sectional area of ​​the grille holes 3-3 is S, which ranges from 3.0 square centimeters to 3.6 square centimeters and can be selected as 3.3 square centimeters. The appropriate size of the grille holes 3-3 facilitates airflow passage, streamlining the airflow and making it smoother and more comfortable. It also effectively filters impurities and mosquitoes, and works in conjunction with filters 12-22 to achieve double-layer filtration, effectively preventing mosquitoes and ensuring clean, fresh filtered air. The small viewing area of ​​the intake grille contributes to aesthetic aesthetics.

[0042] Furthermore, in this embodiment, as shown in Figures 13, 14, and 15, the lower sheet 12-1 is detachably connected to the top plate 13 by a first screw, and the filter frame 12-21 is detachably connected to the lower sheet 12-1 by a second screw. As shown in Figures 13, 14, 15, 17, and 18, a decorative cover 12-3 is provided at the bottom of the lower sheet 12-1, and the first screw sequentially fixes and connects the decorative cover 12-3, lower sheet 12-1, and top plate 13. The decorative cover 12-3 serves the roles of protection and dust prevention, while also being aesthetically pleated. A pleated shading cloth 12-4 is disposed within the decorative cover 12-3, and side air vents 12-31 are provided on the side of the decorative cover 12-3. When the pleated shading cloth 12-4 is deployed, it blocks the ventilation passage 1-1, and the side air vents 12-31 communicate with the ventilation passage 1-1 and the interior of the touring car. After the pleated shading cloth 12-4 is deployed, it increases the airflow volume of the side air vents 12-31, changes the airflow direction, and simultaneously hides imperfections. The pleated shading cloth 12-4 can be patterned to enhance its appearance.

[0043] As shown in FIGS. 18, 19 and 21, a ventilation fan 11-16 is provided in the base 1 of this embodiment, and the ventilation fan 11-16 is located in the ventilation passage 1-1.

[0044] The removal process of the filter component 12-2 is as follows: To remove the lower assembly 12, first remove the first screw, and then remove the second screw to remove the filter component 12-2 from the lower assembly 12. This extremely easy installation and removal facilitates routine maintenance, repair, and cleaning of the filter 12-22.
