Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof technology, and in particular to an automotive sunroof drainage mechanism. Background Technology

[0002] In automotive design, the sunroof, as a crucial feature enhancing the driving and riding experience, directly impacts the vehicle's safety and durability through its drainage performance. However, existing sunroof drainage systems often become clogged over time due to dust, mud, and other debris entering the drainage channels. Once clogged, rainwater cannot drain properly, easily leading to water seepage into the cabin, damage to interior components, and corrosion of the vehicle's metal structure, resulting in unnecessary maintenance costs and safety hazards for users. Currently, while some sunroof drainage systems incorporate a single filter to filter the drainage channels or holes, this limited filtration structure makes it difficult to effectively intercept debris of varying sizes, maintaining a high risk of clogging. Furthermore, existing filters are often fixed in place, requiring users to disassemble sunroof components for cleaning when a significant amount of debris adheres to the filter surface—a cumbersome and time-consuming process. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a car sunroof drainage mechanism that solves the problem that a single filter screen is difficult to effectively intercept debris of different sizes, and solves the problem that fixing the filter screen and maintaining it is troublesome.

[0004] This utility model also provides a car sunroof drainage mechanism as described above, comprising: a sunroof body, the sunroof body including a window, a drainage channel and a drainage hole, a fixing block fixedly connected to the inner wall of the drainage channel, a pneumatic telescopic rod fixedly connected to the outer surface of the fixing block, a sliding block fixedly connected to the output end of the pneumatic telescopic rod, a connecting rod hinged to the upper surface of the sliding block, a filter screen one hinged to one end of the connecting rod, a connecting frame fixedly connected to the outer surface of the sliding block, a filter screen two fixedly connected to one end of the connecting frame, and the filter screen two being located inside the drainage hole.

[0005] Preferably, the lower surface of the first filter screen is rotatably connected to the fixed block, and the first filter screen is located inside the drainage trough. The first filter screen being located inside the drainage trough ensures that the first layer of filtration intercepts large particles before the water flows into the drainage hole, reducing the direct impact of impurities on the drainage hole and the risk of clogging.

[0006] Preferably, the drainage channel is located below the window, and the drainage hole and the fixing block are located at both ends of the drainage channel, so that rainwater can directly enter the drainage channel by placing the drainage channel below the window.

[0007] Preferably, the outer surface of the sliding block is slidably connected to the drainage channel, and the second filter screen is located below the first filter screen. The sliding connection between the sliding block and the drainage channel enables the controllable displacement of the second filter screen and the first filter screen, which facilitates the maintenance of the first filter screen and the second filter screen.

[0008] Preferably, the outer surface of the connecting frame is in contact with the inner wall of the drainage trough, and both the outer surface of the connecting frame and the inner wall of the drainage trough are smooth surfaces. The close and smooth contact surfaces are conducive to achieving better movement and making the movement of the connecting frame smoother.

[0009] Preferably, both the connecting rod and the pneumatic telescopic rod are located inside the drainage trough, with the connecting rod positioned above the pneumatic telescopic rod. This arrangement effectively conceals the drive mechanism and enhances aesthetics.

[0010] Preferably, four drainage channels are provided and are evenly distributed on the main body of the skylight. Even distribution helps to balance the water flow path and reduce water accumulation in local areas.

[0011] Beneficial effects: The automotive sunroof drainage mechanism of this technical solution filters the drainage channel and drainage hole through filter screen one and filter screen two. The double-screen structure provides double-layer filtration, reducing the risk of drainage hole blockage. The pneumatic telescopic rod allows the filter screen to be removed from the drainage channel and drainage hole when cleaning is required, making it convenient for users to maintain and clean.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] Reference Figure 1-5This utility model discloses a sunroof drainage mechanism for automobiles, comprising: a sunroof body 1, which serves as the main load-bearing and working carrier of the overall sunroof system, supporting moving parts, sealing structures, drainage mechanisms, and auxiliary sensors and drive components, realizing the opening / closing, airtightness, and watertightness of the sunroof. It mainly consists of a frame, a cover, sealing components, and auxiliary mechanism fixing surfaces, etc. The opening and closing of the sunroof sash is achieved through guide rails, hinges, and sealing structures. The drainage system and drive components are embedded or fixed within the sunroof body 1. The sealing and drainage design prevents moisture from entering the vehicle cabin while ensuring a balanced distribution of volume and weight. The sunroof body 1 includes a window 101, which serves as a... The movable / fixable light-transmitting / sun-shading interface directly affects the vehicle's interior lighting, ventilation, and airtightness. It mainly consists of the window sash body and sealing assembly, connecting the window 101 to the sunroof body 1 via hinges. Angle control and opening / closing switching are achieved under the action of a drive component. The sealing assembly is pressed tightly when closed to prevent moisture infiltration. A drainage channel 102 and drainage hole 103 are included. The drainage channel 102 collects and guides rainwater from the sunroof cavity into the drainage hole 103, preventing moisture accumulation in the sunroof cavity that could cause leakage or corrosion. Its inner wall is inclined; after entering the drainage channel 102, water flows along the guide path of the channel lining to the drainage hole 103. The channel design must balance water volume, flow rate, and debris. The system has excellent water interception capabilities to prevent overload. The drain hole 103 quickly discharges water from the drain trough 102 to the outside, preventing water accumulation that could cause corrosion, atomization, or leakage into the vehicle compartment. Water is driven out of the drain hole 103 by gravity and fluid potential energy. A fixing block 2 is fixedly connected to the inner wall of the drain trough 102, providing positioning, support, and a rotation bearing point for the filter screen 6. A pneumatic telescopic rod 3 is fixedly connected to the outer surface of the fixing block 2, providing displacement for the filter screen 6 and the filter screen 8. This rod mainly consists of a cylinder body, piston rod, seals, valve control unit, and pipeline interface. The piston extends and retracts through changes in compressed air pressure, which in turn moves the sliding block 4 to achieve relative movement of the filter screens. The output end of the pneumatic telescopic rod 3 is fixedly connected to a sliding block 4. A connecting rod 5 is hinged to the upper surface of the sliding block 4. A filter screen 6 is hinged to one end of the connecting rod 5. This is the first filter screen, which intercepts larger particles, protects the drain hole 103 and the drain trough 102, and improves the subsequent drainage efficiency and lifespan. Driven by the power of fluid (rainwater, etc.), the mesh intercepts particles, and air / water enters the drain trough 102 through the mesh. A connecting frame 7 is fixedly connected to the outer surface of the sliding block 4. A filter screen 8 is fixedly connected to one end of the connecting frame 7. This is the second filter screen, which intercepts smaller particles and protects the drain hole 103. The filter screen 8 is located inside the drain hole 103.

[0016] The lower surface of filter screen 6 is rotatably connected to the fixing block 2. Filter screen 6 is located inside the drainage channel 102. The drainage channel 102 is located below the window 101. The drainage hole 103 and the fixing block 2 are located at the two ends of the drainage channel 102, respectively. The outer surface of the sliding block 4 is slidably connected to the drainage channel 102. Filter screen 8 is located below filter screen 6. The outer surface of the connecting frame 7 is in contact with the inner wall of the drainage channel 102. Both the outer surface of the connecting frame 7 and the inner wall of the drainage channel 102 are smooth surfaces. The connecting rod 5 and the pneumatic telescopic rod 3 are located inside the drainage channel 102. The connecting rod 5 is located above the pneumatic telescopic rod 3. There are four drainage channels 102, which are evenly distributed on the skylight body 1.

[0017] Working principle: During use, filter screen 6 and filter screen 8 filter the drain tank 102 and drain hole 103. The double-screen structure provides double-layer filtration, reducing the risk of clogging of drain hole 103. The extension and retraction of the pneumatic telescopic rod 3 moves the sliding block 4, bringing filter screen 8 out of drain hole 103. When the sliding block 4 moves, the connecting rod 5 moves, pushing filter screen 6 upward, so that filter screen 6 is separated from drain tank 102. This allows the filter screen to be separated from drain tank 102 and drain hole 103 when cleaning is required, making it convenient for users to maintain and clean.

[0018] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
