Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a drainage structure and sliding window assembly for a sliding window. Background Technology

[0002] Invisible recessed sliding windows are created by cutting holes in a large pane of sealed glass, then attaching a window frame to the glass and installing small, sliding panes of glass. This method of installing sliding windows on open glass integrates them seamlessly with the sealed glass, resulting in a clean and aesthetically pleasing appearance. It is widely used in the windows of vehicles such as buses.

[0003] Currently, traditional sliding windows have a drainage structure with internal and external drainage holes in the aluminum profile drainage channel, connecting the inside and outside of the vehicle. However, when the vehicle is traveling at high speed, due to pressure differences, airflow enters the vehicle through the external drainage holes, often generating significant wind noise or a sharp, whistling sound, affecting the passenger experience. In other words, conventional sliding window structures are insufficient in terms of sealing and noise reduction, failing to meet the comfort and quietness requirements of modern buses. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a drainage structure and sliding window assembly for a sliding window, so as to overcome the defects of the existing sliding window structure in terms of insufficient sealing and noise reduction capabilities.

[0007] A drainage cavity is disposed within the guide rail and is used to communicate with the external space;

[0008] The drainage components are distributed perpendicular to the distribution direction of the drainage chamber. The drainage components are at least partially disposed at the bottom of the guide rail, and the guide rail is unidirectionally connected to the drainage chamber through the drainage components.

[0009] Furthermore, the drainage assembly includes a base and a stop plate, the base being disposed within the drainage cavity; the base is provided with a water outlet, the stop plate being rotatably connected to the base, and the stop plate being capable of closing or opening the water outlet.

[0010] Furthermore, the guide rail includes a guide portion; the base is provided with a water outlet slope, which slopes from the side of the base away from the water outlet to the side of the base near the water outlet in a direction that gradually moves away from the guide portion.

[0011] Furthermore, the drainage assembly also includes a limiting structure disposed on the base, so that the stop plate can abut against the limiting structure.

[0012] Furthermore, the upper surface of the base is flush with the bottom surface of the guide portion; or, the upper surface of the base is lower than the bottom surface of the guide portion.

[0013] Furthermore, the lower surface of the base abuts against the bottom surface of the drainage cavity.

[0014] Furthermore, the side wall of the guide portion is provided with a first drain outlet, which is connected to the drainage assembly.

[0015] Furthermore, the drainage cavity also includes a second drainage outlet, which is connected to the drainage assembly;

[0016] The second drain outlet is located on the outer wall of the drainage cavity, and the second drain outlet is located on the outer wall of the drainage cavity away from the base.

[0029] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] The existing sliding window structure is insufficient in terms of sealing and noise reduction capabilities, making it difficult to meet the requirements of modern buses for comfort and quietness.

[0031] Based on this, please refer to Figures 1 to 7 A drainage structure for a sliding window includes: a guide rail 1, a drainage cavity 2, and a drainage component 3. The guide rail 1 is distributed along a first direction; the drainage cavity 2 is disposed within the guide rail 1 and is used to communicate with the external space; the distribution direction of the drainage component 3 is perpendicular to the distribution direction of the drainage cavity 2, and the drainage component 3 is at least partially disposed at the bottom of the guide rail 1, and the guide rail 1 is unidirectionally connected to the drainage cavity 2 through the drainage component 3. That is, the drainage component 3 is disposed within the drainage cavity 2, located in the water outlet direction of the drainage cavity 2, restricting the water flow within the drainage cavity 2 to only flow out unidirectionally through the drainage component 3.

[0032] It is understood that the drainage structure of the sliding window provided by this utility model connects the guide rail 1 and the drainage cavity 2 through the one-way drainage component 3, allowing water in the guide rail 1 to flow through the drainage component 3 to the drainage cavity 2 and thus out of the vehicle. Meanwhile, rainwater and airflow from outside the vehicle cannot enter the vehicle through the drainage component 3, preventing airflow from entering the vehicle and generating noise, thus providing users with a good riding experience.

[0033] In some embodiments, the drainage assembly 3 includes a base 31 and a stop plate 32. The base 31 is disposed within the drainage cavity 2. The base 31 has a water outlet 311, and the stop plate 32 is rotatably connected to the base 31, and the stop plate 32 can close or open the water outlet 311. Specifically, the stop plate 32 in the drainage assembly 3 can rotate relative to the base 31. During drainage, the water flow drives the stop plate 32 to rotate, causing the water to be discharged from the water outlet 311. After the water is discharged, under the action of gravity or external airflow, the stop plate 32 returns to its original position, closing the water outlet 311 and preventing external airflow from entering the vehicle through the water outlet 311, thus avoiding noise generation. This design results in a simple and reliable overall structure, requires fewer components, and is low in cost while ensuring drainage and noise insulation effects. Specifically, those skilled in the art can adjust the amount of water that the base 31 can hold based on factors such as the design vehicle speed, design drainage volume, and the specifications of the guide rail 1, so that the water flow can break through the stop plate 32 during normal driving and discharge it, so that drainage and prevention of airflow from entering the vehicle are balanced, without making specific limitations.

[0034] In some embodiments, the guide rail 1 includes a guide portion 12, and a water outlet slope 312 is provided in the base 31. The water outlet slope 312 gradually slopes away from the side of the base 31 away from the water outlet 311 to the side of the base 31 closer to the water outlet 311, gradually moving away from the guide portion 12. That is, the closer to the water outlet 311, the lower the height of the water outlet slope 312, so that the water flow can be guided to the water outlet 311, avoiding residue and ensuring the drainage effect. Specifically, the guide portion 12 is the part of the overall structure of the guide rail 1 used to place the sliding window glass. A slight inclination can be provided at the bottom of the guide portion 12 to direct the water flow towards the drainage assembly. Those skilled in the art can set a suitable guide portion 12 according to actual needs, without specific limitations.

[0035] In some embodiments, the drainage assembly 3 further includes a limiting structure 33, which is disposed on the base 31 so that the stop plate 32 can abut against the limiting structure 33. The limiting structure restricts the relative position of the stop plate 32 and the base 31, preventing the stop plate 32 from rotating excessively and ensuring that external airflow cannot enter the vehicle. Specifically, the limiting structure 33 can be a limiting block, a limiting surface, or other structures, and can be integrated with the base 31. It only needs to be able to restrict the position of the stop plate 32. Those skilled in the art can set a suitable limiting structure 33 according to actual needs, without making specific limitations.

[0036] In some embodiments, the upper surface of the base 31 is flush with the bottom surface of the guide portion 12; or, the upper surface of the base 31 is lower than the bottom surface of the guide portion 12. This arrangement allows the water flow in the guide rail 1 to flow sufficiently along the guide portion 12 to the drainage assembly 3, ensuring the drainage effect and further reducing residual water in the guide rail 1.

[0037] In some embodiments, the lower surface of the base 31 abuts against the bottom surface of the drainage cavity 2. This arrangement ensures that the entire drainage cavity 2 is blocked by the base 31, preventing external airflow from entering the drainage cavity 2 through the gap between the base 31 and the drainage cavity 2, thereby further reducing noise.

[0038] In some embodiments, a first drain outlet 11 is provided on the side wall of the guide portion 12, and the first drain outlet 11 is connected to the drainage assembly 3. After the first drain outlet 11 is provided, water in the guide portion 12 can flow out along the first drain outlet 11 and enter the drainage assembly 3 from the top of the drainage cavity 2. When the water flow in the guide portion 12 is too large, the drainage flow rate can be increased, the drainage efficiency can be improved, and the excessive water flow can be prevented from overflowing from the guide portion 12 into the vehicle, thus ensuring the drainage effect.

[0039] In some embodiments, the drainage cavity 2 further includes a second drain outlet 21, which communicates with the drainage assembly 3. The second drain outlet 21 is located on the outer wall of the drainage cavity 2, away from the base. Specifically, the second drain outlet 21 is positioned in the drainage direction, and the guide rail 1 is connected to the outside of the vehicle through the second drain outlet 21. Water flows along the route from the drainage assembly 3, the drainage cavity 2 to the second drain outlet 21, and is discharged to the outside of the vehicle.

[0040] In some embodiments, at least two drainage components 3 are spaced apart, and a second drain outlet is disposed between two adjacent drainage components 3. Multiple drainage components 3 are provided on the vehicle, and a second drain outlet is provided between two drainage components 3 to allow water in the drainage chamber 2 to be discharged in a timely manner, enhancing drainage efficiency and ensuring drainage effect. Specifically, each drainage component 3 has a second drain outlet in the drainage direction to ensure water can flow out.

[0041] This utility model also provides a sliding window assembly, including sliding window glass and a drainage structure of the sliding window as described above, wherein the sliding window glass is disposed on the drainage structure of the sliding window.

[0042] Please refer to Figures 1 to 5 One embodiment of this utility model is a drainage structure for a sliding window, comprising: a guide rail 1, a drainage cavity 2, and a drainage component 3. The guide rail 1 is distributed along a first direction; the drainage cavity 2 is disposed within the guide rail 1 and is used to communicate with the external space; the distribution direction of the drainage component 3 is perpendicular to the distribution direction of the drainage cavity 2, and the drainage component 3 is at least partially disposed at the bottom of the guide rail 1, and the guide rail 1 is unidirectionally connected to the drainage cavity 2 through the drainage component 3.

[0043] The drainage assembly 3 includes a base 31 and a stop plate 32. The base 31 is disposed inside the drainage cavity 2. The base 31 has a water outlet 311. The stop plate 32 is rotatably connected to the base 31 and can close or open the water outlet 311. The guide rail 1 also includes a first drain outlet 11, which is opened on the side wall of the guide rail 1 above the drainage assembly 3.

[0044] In this embodiment, the guide rail 1 includes a guide portion 12, and the base 31 has a water outlet slope 312. The water outlet slope 312 gradually slopes away from the side of the base 31 away from the water outlet 311 and towards the side of the base 31 closer to the water outlet 311, moving away from the guide portion 12. The drainage assembly 3 also includes a limiting structure 33, which is disposed on the base 31 so that the stop plate 32 can abut against the limiting structure 33.

[0045] In this embodiment, the upper surface of the base 31 is flush with the bottom surface of the guide rail 1, and the lower surface of the base 31 abuts against the bottom surface of the drainage cavity 2.

[0046] In this embodiment, the drainage cavity 2 further includes a second drainage outlet 21, which is connected to the drainage assembly 3. The second drainage outlet 21 is formed on the outer wall of the drainage cavity 2, and is located on the outer wall of the drainage cavity 2 away from the base.

[0047] The working principle of this utility model is as follows: When drainage is required, rainwater flows along the sliding window glass to the guide section 12, and then enters the base 31 set at the bottom of the guide section 12. The water flows along the outlet slope 312 to the outlet 311. The stop plate 32 rotates under the gravity of the water flow, and then the water flows into the drainage cavity 2 and flows out through the second drain outlet. External airflow blows from the second drain outlet to the stop plate 32, causing the stop plate 32 to rotate back to its original position. After abutting against the limiting structure 33, it closes the outlet 311, preventing airflow from entering the guide section 12 and avoiding noise generation.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
