Description

Technical Field

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

Background Art

[0002] On the upper part of an existing touring car, a sunroof including a base and an outer lid is provided. A ventilation passage penetrates through the base, and the front end of the outer lid is hinge-connected to the front end of the base. In a state where the sunroof is open, the outer lid is rotated upward away from the base so that the ventilation passage communicates the interior of the vehicle with the exterior of the vehicle. The outer lid rotates until it approaches the base and covers the air intake of the ventilation passage, and at this time the sunroof is in a closed state. The sunroof for a touring car disclosed in the conventional patent CN205097897U has the following defects: the air intake of the ventilation passage communicates directly with the outside, and no air intake grill is provided. On the one hand, dust and the like are likely to enter the ventilation passage and the interior of the vehicle. On the other hand, the air flow directly collides with the intake passage, easily destroys the internal structure of the sunroof, and the comfort is poor due to the air flow turbulence. To solve the above problems, there is a potentially driven electric curtain with improved coil strength and / or a manufacturing method thereof as disclosed in the prior patent US10858884B2, and it is specifically disclosed that the foldable ventilation holes are closed. An air intake grill is hinge-connected between the outer lid and the base. The air intake grill is located behind the base and outside the air intake of the ventilation passage, but the mounting structure of the air intake grill is complicated, difficult to remove, difficult to clean afterwards, and the conventional air intake grill is easy to loosen, causing shaking and abnormal noise.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In order to solve the problem that the air intake grill of the sunroof of a touring car existing in the prior art is difficult to remove, the present invention provides an air intake structure of a vehicle sunroof and a touring car with a sunroof.

Means for Solving the Problem

[0004] To solve the above technical problem, the technical solution adopted by the present invention is as follows. It is an air intake structure for a vehicle sunroof, including a base, an outer lid, and an air intake grille. The front end of the base and the front end of the outer lid are hinged. A ventilation passage penetrates through the base. The air intake grille is provided below the rear end of the outer lid. The air intake grille is detachably connected to the outer lid. The air intake grille is located outside the air intake of the ventilation passage. When the outer lid cooperates with the base to cover the air intake, a relief gap is formed between the air intake grille and the base. When the outer lid rotates away from the base to open the air intake, the outer lid moves the air intake grille closer to the base, and the relief gap is gradually narrowed. At this time, the air flow from outside the vehicle compartment flows into the vehicle compartment through the air intake grille, the air intake, and the ventilation passage in sequence.

[0005] A roller assembly is provided at one end of the air intake grille close to the base. The roller assembly includes a roller wheel. A rail is provided on the base. The rail is matched with the rotation path of the air intake grille so that the roller wheel always abuts against the rail during the rotation of the air intake grille.

[0006] The roller assembly further includes a rotating shaft and a connecting rod. A guide groove is provided on the air intake grille. One end of the connecting rod is slidably provided in the guide groove, and the other end of the connecting rod is connected to the rotating shaft. The roller wheel is fitted on the rotating shaft, and a spring is arranged between one end of the connecting rod away from the rotating shaft and the guide groove.

[0007] Due to the action of the spring, the roller wheel is always pressed against the rail, eliminating the rocking gap formed by the opening and closing of the outer lid due to the undulation of the rail. The structure of the roller assembly is simple, highly reliable, ingeniously designed, and operates smoothly.

[0008] Furthermore, when the opening angle of the outer cover is α, α is in the range of 0° < α ≤ 10°. This ensures effective ventilation of the sunroof after the outer cover is opened, while also ensuring the reliability, stability, safety, and aesthetics of the sunroof.

[0009] Preferably, a sealing ring is provided at the air intake. When the outer cover and the base cooperate to cover the air intake, the outer cover contacts the sealing ring. This ensures the sealing performance after the outer cover is closed and effectively avoids air leakage and water leakage of the sunroof.

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

[0011] Furthermore, a plurality of support rods are fixedly provided at the bottom of the outer cover. The plurality of support rods are sequentially installed on the outer periphery of the air intake grille, and the bolts sequentially connect the air intake grille and the support rods. This optimizes the attachment structure of the air intake grille and improves the reliability and stability of the air intake grille attachment.

[0012] A touring car with a sunroof, including the air intake structure of any of the above vehicle sunroofs, wherein the base is provided at 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 rotates the outer cover 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 group and a handle. The screw is horizontally provided on the base along the width direction of the touring car and is located behind the ventilation passage. The bottom end of the first cantilever is screwed to the screw by a first slider, and the bottom end of the second cantilever is screwed to 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 a holder, and the first cantilever and the second cantilever are provided intersecting each other. The output end of the motor is connected to one end of the screw. The input end of the gear group is connected to the handle, and the output end of the gear group is connected to the end of the screw away from the motor. When the screw rotates, the first cantilever and the second cantilever move closer to or away from each other. When it is necessary to manually control the opening and closing of the outer cover, especially in the case of a power outage, it is only necessary to manually rotate the handle in the touring car. The handle further rotates the screw via the gear group. When the screw rotates, the first slider and the second slider slide along the screw. When the first slider and the second slider slide closer to or away from each other, the first cantilever and the second cantilever rotate the outer cover upward to open it or rotate the outer cover downward to close it. The transmission of the gear group is stable, the transmission efficiency is high, especially compared with the transmission efficiency of the flexible shaft, the manual operation is labor-saving and easy.

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

[0015] The lower assembly includes a lower seat and a filter component. The ventilation passage penetrates the lower seat. The filter component includes a filter frame and a filter provided on the filter frame. The filter frame is detachably connected to the lower seat, and the filter is located in the ventilation passage.

[0016] The base and the lower seat are respectively provided on the upper and lower sides of the top plate of the touring car. The bottom of the base forms a first cylindrical portion, and the top of the filter frame forms a second cylindrical portion. The first cylindrical portion and the second cylindrical portion are movably fitted along the thickness direction of the top plate. When the outer cover opens the ventilation passage, the outside of the touring car, the intake grill, the ventilation passage, the filter, and the inside of the touring car are sequentially communicated.

[0017] When maintaining the filter component, first remove the lower assembly, and then remove the filter component from the lower assembly. The detachment is very easy, and the daily maintenance, upkeep, and cleaning of the filter are easy. At the same time, since the second cylindrical portion of the filter frame is fitted to the first cylindrical portion of the base and is movable along the thickness direction of the top plate, it can be adapted to the top plates of touring cars with different thicknesses. That is, after the second cylindrical portion of the filter frame and the first cylindrical portion of the upper seat are moved along the thickness direction of the top plate, they are adapted to the top plates of touring cars with different thicknesses. At this time, the first cylindrical portion and the second cylindrical portion still maintain a fitted state, ensuring the passage of air flow, and skillfully realizing the easy removal of the filter component and the adaptation to the top plates of touring cars with different thicknesses at the same time.

[0018] Furthermore, the inclination angle of the grill holes is β, and the range of the value of β is 30° to 60°. This ensures that the connection between the grill holes and the inside of the outer cover is smooth, there is no blockage during both intake and exhaust, the air flow is smoother, and the ventilation volume is effectively increased.

[0019] Furthermore, the cross-sectional area of the grill holes is S, and the value range of S is 3.0 square centimeters to 3.6 square centimeters. The size of the grill holes is appropriate, which is beneficial for the passage of the air flow, arranges the air flow, makes the air flow smoother and more comfortable. It can also effectively filter impurities and mosquitoes, etc., and further cooperate with the filter to achieve two-layer filtration, effectively prevent mosquitoes, and make the filtered air clean and fresh. The perspective area of the intake grill is small and aesthetically pleasing.

[0020] Furthermore, the lower sheet is detachably connected to the top plate by the first screw, and the filter frame is detachably connected to the lower sheet by the second screw. First, remove the first screw to remove the lower assembly, and then remove the second screw to remove the filter component from the lower assembly. The detachment and attachment are very easy, which makes the daily maintenance, upkeep and cleaning of the filter easy.

[0021] Furthermore, a decorative cover is provided at the bottom of the lower sheet, and the first screw sequentially fixedly connects the decorative cover, the lower sheet and the top plate. The decorative cover plays a role in protection and dust prevention, and is aesthetically pleasing at the same time.

[0022] Furthermore, a pleated light-shielding cloth is arranged inside the decorative cover, and side air vents are provided on the side surface of the decorative cover. When the pleated light-shielding cloth is unfolded, the pleated light-shielding cloth blocks the ventilation passage, and the side air vents communicate with the ventilation passage and the inside of the touring car respectively. After the pleated light-shielding cloth is unfolded, the air volume blown out from the side air vents is increased, the blowing direction of the blown air is changed, and at the same time, it plays a role in hiding the roughness. Patterns can be set on the pleated light-shielding cloth to make it look better.

The roller wheel 9-1 is fitted on the rotating shaft 9-2, and a spring 9-4 is provided between one end of the connecting rod 9-3 away from the rotating shaft 9-2 and the guide groove 3-2. Due to the action of the spring 9-4, the roller wheel 9-1 is always pressed against the rail 1-3, eliminating the rocking gap caused by the up and down undulations of the rail 1-3 when the outer cover 2 opens and closes, and capable of limiting the maximum opening angle of the outer cover 2. The structure of the roller assembly 9 is simple, highly reliable, ingeniously designed, and operates smoothly.

[0034] In order to ensure the sealing performance after the outer cover 2 is closed and effectively avoid air leakage and water leakage of the sunroof, in this embodiment, as shown in FIG. 5, a sealing ring 7 is provided at the air intake 1-2. When the outer cover 2 and the base 1 cooperate to cover the air intake 1-2, the outer cover 2 contacts the sealing ring 7.

[0035] As shown in FIGS. 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 the ventilation passage 1-1 or rotate it downward to close the ventilation passage 1-1. In this embodiment, when the opening angle of the outer cover 2 is α, α is in the range of 0° < α ≦ 10°. This ensures effective ventilation of the sunroof after the outer cover 2 is opened, and at the same time ensures 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.

[0036] A touring car with a sunroof, including an air intake structure of the vehicle sunroof, wherein the base 1 is provided at the top of the touring car, and both the outer cover 2 and the air intake grille 3 are exposed from the touring car.

[0037] The operating principle is as follows: The opening process of the air intake structure of the vehicle sunroof is as follows: First, the outer cover 2 rotates away from the base 1 to open the air intake port 1-2. At the same time, the outer cover 2 moves the air intake grille 3 closer to the base 1, and the escape gap 4 is gradually narrowed. During the rotation of the air intake grille 3, the roller wheel 9-1 always abuts against the rail 1-3 under the action of the spring 9-4. After the outer cover 2 is fixed at a certain opening angle, the roller wheel 9-1 supports the outer cover 2 additionally. At this time, the air intake port 1-2 communicates with the outside of the vehicle through the air intake grille 3, and the air flow outside the vehicle flows into the vehicle interior along the air intake grille 3, the air intake port 1-2, and the ventilation passage 1-1.

[0038] The closing process of the air intake structure of the vehicle sunroof is as follows: First, the outer cover 2 rotates towards the base 1. At the same time, the outer cover 2 moves the air intake grille 3 away from the base 1, gradually forming an escape gap 4 between the air intake grille 3 and the base 1. During the rotation of the air intake grille 3, the roller wheel 9-1 always abuts against the rail 1-3 under the action of the spring 9-4. The roller wheel 9-1 remains to support the outer cover 2 additionally until the outer cover 2 covers the air intake port 1-2 and the outer cover 2 contacts the sealing ring 7 for sealing.

[0039] The removal process of the air intake structure of the vehicle sunroof is as follows: Just remove a plurality of screws between the air intake grille 3 and the support rod 8, and the air intake grille 3 can be removed. The attachment and detachment of the air intake grille 3 are easy, and it is easy to remove the air intake grille 3 for maintenance such as cleaning.

[0040] [Embodiment 2] As shown in FIGS. 12 to 21, in this embodiment, the difference from Embodiment 1 is that, as shown in FIGS. 14, 15, 17, and 18, the vehicle sunroof includes an upper assembly 11 and a lower assembly 12, and the base 1, the outer lid 2, and the intake grill 3 constitute the upper assembly 11. The intake grill 3 is horizontally arranged when the outer lid 2 closes the ventilation passage 1-1, and each grill hole 3-3 is arranged to gradually incline forward from bottom to top. As shown in FIGS. 14 and 15, the lower assembly 12 includes a lower seat 12-1 and a filter component 12-2. The ventilation passage 1-1 penetrates the lower seat 12-1. The filter component 12-2 includes a filter frame 12-21 and a filter 12-22 provided on the filter frame 12-21. The filter frame 12-21 is detachably connected to the lower seat 12-1, and the filter 12-22 is located in the ventilation passage 1-1. As shown in FIGS. 13, 14, 19, and 21, the base 1 and the lower seat 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. The first cylindrical portion 1-4 and the second cylindrical portion 12-211 are movably fitted along the thickness direction of the top plate 13. When the outer lid 2 opens the ventilation passage 1-1, the outside of the touring car, the intake grill 3, the ventilation passage 1-1, the filter 12-22, and the inside of the touring car are sequentially communicated.

[0041] Furthermore, in this embodiment, as shown in FIG. 20, the inclination angle of the grill hole 3-3 is β, and the value range of β is 30° to 60°, and β can be selected as 45°. This ensures smooth connection between the grill hole 3-3 and the interior of the outer lid 2, without any blockage during both intake and exhaust, allowing the air flow to be smoother and effectively increasing the ventilation volume. The cross-sectional area of the grill hole 3-3 is S, and the value range of S is 3.0 square centimeters to 3.6 square centimeters, and S can be selected as 3.3 square centimeters. The size of the grill hole 3-3 is appropriate, which is beneficial for the passage of air flow, organizes the air flow, and makes the air flow smoother and more comfortable. It also effectively filters impurities and mosquitoes, etc., and further cooperates with the filter 12-22 to achieve two-layer filtration, effectively preventing mosquitoes and ensuring that the filtered air is clean and fresh. The perspective area of the intake grill is small and aesthetically pleasing.

[0042] Furthermore, in this embodiment, as shown in FIGS. 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 FIGS. 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 fixedly connects the decorative cover 12-3, the lower sheet 12-1, and the top plate 13. The decorative cover 12-3 serves the functions of protection and dust prevention, and is aesthetically pleasing at the same time. A pleated light-shielding cloth 12-4 is arranged inside the decorative cover 12-3, and a side air vent 12-31 is provided on the side surface of the decorative cover 12-3. When the pleated light-shielding cloth 12-4 is unfolded, the pleated light-shielding cloth 12-4 blocks the ventilation passage 1-1, and the side air vent 12-31 communicates with the ventilation passage 1-1 and the interior of the touring car respectively. After the pleated light-shielding cloth 12-4 is unfolded, the air volume blown out from the side air vent 12-31 is increased, the blowing direction of the blown air is changed, and at the same time, it plays a role in hiding the roughness. Patterns can be set on the pleated light-shielding cloth 12-4 to make it look better.

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

[0044] The removal process of the filter component 12-2 is as follows: First, remove the first screw to remove the lower assembly 12, and then remove the second screw to remove the filter component 12-2 from the lower assembly 12. The attachment and detachment are very easy, and the daily maintenance, repair and cleaning of the filter 12-22 are easy. It should be particularly noted that the second cylindrical portion 12-211 of the filter frame 12-21 is fitted into the first cylindrical portion 1-4 of the base 1 and can move along the thickness direction of the top plate 13, so it can be adapted to two-wheeled vehicle top plates 13 of different thicknesses. That is, after moving the second cylindrical portion 12-211 of the filter frame 12-21 and the first cylindrical portion 1-4 of the base 1 along the thickness direction of the top plate 13, they can be adapted to two-wheeled vehicle top plates 13 of different thicknesses.
