Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive waterproofing technology, specifically relating to a frameless automotive interior water-blocking and water-guiding structure. Background Technology
[0002] With the rapid development of the automotive industry and the increasing demands of consumers for automotive comfort, frameless window designs have gained widespread attention due to their stylish and aesthetically pleasing features. However, frameless windows also face a series of technical challenges in their design and use, among which water accumulation and icing, as well as abnormal noises during window operation, are particularly prominent issues.
[0003] Frameless car windows, when closed, leave a gap between the window glass and the car body, especially at the inner sill, where rainwater or snowmelt can easily accumulate. In cold weather, this accumulated moisture freezes quickly, causing the gap between the window glass and the car body to freeze and affecting the normal operation of the window.
[0004] When car windows encounter water or ice during operation, additional friction and resistance are generated, causing abnormal noises and potentially damaging the window regulator mechanism. These noises not only affect the driving experience but can also cause further damage to the window regulator system.
[0005] Therefore, a frameless car interior water-blocking and guiding structure is needed to solve the problems of water accumulation and freezing, as well as abnormal noises when raising and lowering windows. Utility Model Content
[0006] To address the aforementioned problems in the existing technology, this utility model provides a frameless automotive interior water-blocking and guiding structure, which solves the problem that when the car window encounters water accumulation or ice during the raising and lowering process, additional friction and resistance will be generated, resulting in abnormal noises during the raising and lowering process.
[0007] The objective of this utility model can be achieved through the following technical solutions:
[0008] A frameless automotive interior water-blocking and water-guiding structure includes an N-shaped inner water cutter, which is connected to the sheet metal of the car window glass. The lower part of the N-shaped inner water cutter near the car window glass has two spaced connecting parts, and the two connecting parts are respectively connected to a lip, which abuts against the car window glass.
[0009] The two lips and the inner water cut of the N-shaped structure form an upwardly sloping U-shaped space, which is used to contain accumulated water. The U-shaped space also includes a water guide that communicates with the lower part of the U-shaped space and is used to drain the accumulated water.
[0010] Preferably, the length of the water inlet is 7mm and the width is 4mm.
[0011] Preferably, the water inlet is located at the connection between the connecting part and the lip, and the lowest point of the water inlet is located above the lowest point of the U-shaped space.
[0012] Preferably, the lower lip is shorter than the upper lip, and the lower lip is used to guide water from the window into the U-shaped space.
[0013] Preferably, the water inlet is made of rubber.
[0014] Preferably, there are several water inlets, and each of the several water inlets corresponds to a corner on both sides of the vehicle window.
[0015] The beneficial effects of this utility model are as follows:
[0016] This application reduces the direct contact between the window glass and water or snow during the raising and lowering process by using a tight fit between the lip and the window glass, as well as the U-shaped space to contain water. This reduces additional friction and resistance, effectively avoiding abnormal noise during the raising and lowering process. The design of the U-shaped space and the water inlet makes it easy for water to be drained and cleaned. Attached Figure Description
[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0022] like Figures 1-2 As shown, a frameless automotive interior water-blocking and guiding structure includes an N-shaped inner water cutter 1, which is connected to the car window glass sheet metal, providing stable support and optimizing the water flow guiding path; at the lower part of the N-shaped inner water cutter 1 near the car window glass, there are two spaced connecting parts 11, and each connecting part 11 is connected to a lip 2. The two lips 2 form a tight abutment relationship with the car window glass, effectively preventing external water or ice and snow from directly intruding into the gap between the car window and the car body;
[0023] The U-shaped space 3 formed between the two lips 2 and the N-shaped inner water cut 1 is used to contain accumulated water or melted ice and snow, avoiding direct friction with the car window glass. The lower part of the U-shaped space 3 is provided with a water guide 4, which is connected to the vehicle's drainage system. Once the water in the U-shaped space 3 reaches a certain level, the water will be smoothly discharged through the water guide 4, ensuring that the water does not accumulate too much and that the water brought in from the car window is drained away in time, preventing the water from forming ice and snow on the car window surface, affecting the raising and lowering of the car window glass and generating noise during the raising and lowering process.
[0024] In summary, this application reduces the direct contact between the window glass and water or snow during the raising and lowering process by using the tight contact between the lip 2 and the window glass, and the U-shaped space 3 to contain the water. This reduces additional friction and resistance, effectively avoiding abnormal noise during the raising and lowering process. The design of the U-shaped space 3 and the water inlet 4 makes it easy for the water to be drained and cleaned.
[0025] In one embodiment, the length of the water inlet 4 is 7 mm and the width is 4 mm. The size of the water inlet 4 is not only suitable for drainage needs under normal climatic conditions, but also maintains efficient drainage capacity when there is abundant rain or frequent raising and lowering of car windows leading to increased water accumulation. The 7 mm length ensures that the water has enough space to flow smoothly within the water inlet 4, while the 4 mm width provides appropriate restriction to prevent the water flow from being too dispersed and reducing the flow velocity. This ensures that the water is discharged through the water inlet 4 at an appropriate speed under the action of gravity and airflow generated by vehicle movement, so that the water can be guided out of the U-shaped space 3 in a fast and stable manner, effectively preventing the water from stagnating.
[0026] In one embodiment, the water inlet 4 is located at the connection between the connecting part 11 and the lip 2. When the window glass rises or falls, the lower lip 2 will rotate slightly, so that the outlet flow rate of the water inlet 4 is affected by the lip 2. Due to the contact relationship between the lip 2 and the window, the lip 2 is squeezed towards the side of the U-shaped space 3, squeezing the water in the U-shaped space 3, so that the water can quickly pass through the water inlet 4, thus accelerating the ability of the U-shaped space 3 to process water. Since the lowest point of the water inlet 4 is located above the lowest point of the U-shaped space 3, the water will have a short-term retention and sedimentation process in the U-shaped space 3, which helps to settle larger impurities and particles at the bottom of the U-shaped space 3, preventing them from being directly discharged with the water, thereby reducing the risk of blockage in the drainage system. When the pre-filtered water is discharged through the water inlet 4, its cleanliness is higher, which helps to maintain the long-term smooth and normal operation of the vehicle's drainage system.
[0027] In one embodiment, the lower lip 2 is shorter than the upper lip 2, and the lower lip 2 is used to guide the water accumulated in the window to the U-shaped space 3.
[0028] In one embodiment, the water inlet 4 is made of rubber. The rubber water inlet 4 utilizes its good elastic properties to fit tightly into the gap between the window glass and the vehicle frame, forming an effective seal. When the window glass is raised or lowered, the rubber water inlet 4 can deform appropriately with the movement of the glass, always maintaining a sealed state and preventing external moisture and dust from entering.
[0029] In one embodiment, there are several water inlets 4, which are respectively located at the corners on both sides of the window. The multiple water inlets 4 are respectively located at the corners on both sides of the window, which can form a multi-point drainage system. Through multi-point drainage and rapid flow guidance, this design can significantly improve the drainage efficiency of the window and reduce the impact of water accumulation on the window raising and lowering. At the same time, the design of multiple water inlets 4 can evenly distribute the pressure generated when the window is raised and lowered, reducing the burden on a single water inlet 4.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
