[0004] This utility model provides a sealing structure for a vehicle front corner window, including a main body, the main body comprising:
[0005] A functional component is sealed to the rear end of the front corner window. The rear end of the functional component has a first sealing edge and a second sealing edge. The first sealing edge and the second sealing edge are spaced apart along the Y direction and cooperate with the functional component to form a guide groove. The rear parts of the first sealing edge and the second sealing edge are sealed to the front door glass.
[0006] An extension is located between the front corner window and the side sealing strip, and is sealed to the front corner window and the side sealing strip. The rear end of the extension is connected to the upper front end of the functional component.
[0007] In one embodiment, the upper ends of both the first sealing edge and the second sealing edge interfere with the side sealing strip. The first sealing edge is located inside the second sealing edge, and the upper end of the second sealing edge protrudes beyond the upper end of the first sealing edge, so that the interference between the second sealing edge and the side sealing strip is greater than the interference between the first sealing edge and the side sealing strip.
[0008] In one embodiment, the upper surface of the functional element is configured to be higher than the upper surface of the first sealing edge and / or the second sealing edge, so that the guide groove is recessed relative to the functional element.
[0009] In one embodiment, the upper surface of the functional component is inclined, and the height of the upper surface of the functional component is configured to increase from front to back, so that the amount of interference between the functional component and the side sealing strip increases from front to back.
[0010] In one embodiment, the upper end face of the extension is inclined, and the height of the upper end face of the extension is configured to increase from front to back, so that the amount of interference between the extension and the side sealing strip increases from front to back.
[0011] In one embodiment, the upper end face of the extension and the upper end face of the functional member are at the same height at their connection point.
[0012] In one embodiment, the inner surface of the first sealing edge is sealed to the door opening sealing strip in the Y direction, and the contact surface between the inner surface and the door opening sealing strip is arc-shaped in the Z direction.
[0013] This utility model also proposes a vehicle front corner window assembly, including a front corner window and the aforementioned vehicle front corner window sealing structure, wherein the main body is sealed to the front corner window.
[0014] In one embodiment, a mounting structure is included for mounting the main body and the front corner window to the vehicle body.

[0015] In one embodiment, the second mounting member is configured to be adjustable in the Z direction relative to a fixed position on the vehicle body, and the third mounting member is configured to be adjustable in the X direction relative to a fixed position on the vehicle body.
[0016] The beneficial effects of this utility model are as follows:
[0017] The functional components are designed to provide a sealing connection between the rear end of the front corner window and the front end of the front door glass in the X direction. The first and second sealing edges work together to ensure a tight seal with the front door glass and also form a drainage channel to guide water, preventing water from accumulating at the front corner window and side sealing strips, which could cause curling and leakage in the passenger compartment.

[0031] As attached Figure 1 As shown in the coordinate system, the X, Y, and Z directions in the coordinate system are based on the vehicle coordinate system. The vehicle coordinate system is a special moving coordinate system used to describe the motion of a car. The origin of this coordinate system coincides with the center of mass of the vehicle. When the vehicle is stationary on a horizontal road, the X direction of this coordinate system refers to the direction parallel to the direction of the car's travel, that is, the front-to-back direction, where the arrow indicates the front. The Y direction refers to the width direction of the car, that is, the left-to-right direction, where the arrow indicates the left. The Z direction refers to the height direction of the car, that is, the up-down direction, where the arrow indicates the up.
[0032] Combination Figures 1 to 3 The vehicle front corner window sealing structure proposed in this utility model includes a main body 100, which includes a functional component 101 and an extension component 102. The functional component 101 is sealed to the rear end of the front corner window 200. The rear end of the functional component 101 is provided with a first sealing edge 11 and a second sealing edge 12. The first sealing edge 11 and the second sealing edge 12 are spaced apart along the Y direction and cooperate with the functional component 101 to form a guide groove 13. The rear parts of the first sealing edge 11 and the second sealing edge 12 are sealed to the front door glass. The extension component 102 is located between the front corner window 200 and the side sealing strip 300, and is sealed to the front corner window 200 and the side sealing strip 300. The rear end of the extension component 102 is connected to the upper front end of the functional component 101.
[0033] The functional component 101 provides a sealing connection between the rear end of the front corner window 200 and the front end of the front door glass in the X direction. The first sealing edge 11 and the second sealing edge 12 work together to ensure the sealing of the connection with the front door glass and to form a guide groove 13 to guide water. This helps to prevent water from accumulating at the front corner window 200 and the side sealing strip 300, which could cause the edges to curl and lead to water leakage in the passenger compartment. The extension component 102 improves the sealing of the connection between the upper end of the functional component 101 and the side sealing strip 300, ensuring a good vehicle user experience.
[0034] In an example scheme, such as Figure 4 As shown, the upper ends of both the first sealing edge 11 and the second sealing edge 12 interfere with each other with the side sealing strip 300, thus forming a combination. Figure 3 The first sealing edge 11 is located inside the second sealing edge 12, and the upper end of the second sealing edge 12 protrudes from the first sealing edge 11, so that the interference between the second sealing edge 12 and the side sealing strip 300 is greater than the interference between the first sealing edge 11 and the side sealing strip 300.
[0035] This design ensures the sealing performance at the connection between the first sealing edge 11, the second sealing edge 12, and the side sealing strip 300, preventing gaps from forming due to prolonged use and resulting in poor sealing. The large interference between the second sealing edge 12 and the side sealing strip 300 ensures that rainwater and snow from outside the passenger compartment are unlikely to enter the inner side of the second sealing edge 12. Even if some water does enter the inner side of the second sealing edge 12, it can be guided by the guide groove 13 to prevent it from accumulating inside the second sealing edge 12. This avoids the problem of curling edges between the first sealing edge 11 and the side sealing strip 300, thus helping to prevent water leakage in the passenger compartment.
[0036] For example, the amount of interference between the first sealing edge 11 and the second sealing edge 12 and the side sealing strip 300 after deformation is ≥2mm.
[0037] For example, the difference between the interference between the first sealing edge 11 and the side sealing strip 300 and the interference between the second sealing edge 12 and the side sealing strip 300 is 1mm, which can effectively avoid the problem of water leakage inside the vehicle caused by easy curling between the first sealing edge 11 and the side sealing strip 300.
[0038] For example, the main body 10 is made of EPDM (Ethylene Propylene Diene Monomer).
[0039] In one example scheme, refer to Figure 3The upper end face of the functional component 101 is configured to be higher than the upper end face of the first sealing edge 11 and / or the second sealing edge 12. Furthermore, the rear part of the upper end face of the functional component 101 is configured to be higher than the front part of the upper end face of the first sealing edge 11 and / or the second sealing edge 12, so that the guide groove 13 is recessed in the Z direction relative to the functional component 101, thereby avoiding water accumulation between the functional component 101 and the side sealing strip 300, which would easily cause the functional component 101 and the side sealing strip 300 to curl and cause water leakage into the passenger compartment.
[0040] In an example scheme, such as Figure 3 As shown, the upper surface of the functional component 101 is inclined, and the height of its upper surface is configured to increase from front to back, so that the interference between the upper end of the functional component 101 and the side sealing strip 300 increases from front to back. This configuration helps to avoid the problem of a step difference between the functional component 101 and the side sealing strip 300 affecting the sealing performance.
[0041] For example, the amount of interference between the upper end of the functional component 101 and the side sealing strip 300 varies linearly.
[0042] For example, such as Figure 3 As shown, the upper end face of the extension 102 is inclined, and the height of its upper end face is configured to increase from front to back, so that the interference between the upper end of the extension 102 and the side sealing strip 300 increases from front to back. This configuration helps to avoid the problem of a step difference between the extension 102 and the side sealing strip 300 affecting the sealing performance.
[0043] Optionally, the amount of interference between the upper end of the extension 102 and the side sealing strip 300 varies linearly.
[0044] Optionally, the upper surface of the functional component 101 and the upper surface of the extension 102 are inclined as a whole, and the connection between the functional component 101 and the extension 102 is naturally transitioned. That is, the upper surface of the functional component 101 and the upper surface of the extension 102 are at the same height at the connection between them. The interference between the functional component 101 and the extension 102 and the side sealing strip 300 changes linearly from 4.5mm to 4.0mm, which helps to ensure the sealing between the main body 10 and the side sealing strip 300 and can effectively avoid the problem of water seepage and leakage in the front corner window 200.
[0045] For example, such as Figure 3 As shown, L represents the length of the extension 102, and D1 represents the thickness of the front end of the extension 102. The length L of the extension 102 is ≥ 8 mm, and the thickness D1 of the front end of the extension 102 is configured to be ≤ 0.3 mm. This setting ensures that the extension 102 transitions evenly and stably from front to back, and also ensures that the interference between it and the side sealing strip 300 is uniform, which is beneficial to improving the sealing performance.
[0046] For example, such as Figure 3 As shown, D2 represents the distance between the rear ends of the first sealing edge 11 and the second sealing edge 12. The distance D2 ≤ 3.5mm. Since the first sealing edge 11 and the second sealing edge 12 are used to contact the front door glass, the setting of the distance D2 can ensure the sealing of the connection between the first sealing edge 11 and the second sealing edge 12 and the front door glass.
[0047] In one example, the X-axis dimension between the front wall of the guide channel 13 (i.e., the rear end of the functional component 101) and the front end of the window glass is configured to be ≥5mm. This configuration enables the guide channel 13 to have good water guiding function, allowing water to be discharged efficiently through the guide channel 13.
[0048] In an example scheme, such as Figure 5 As shown, the inner surface 110 of the first sealing edge 11 is sealed to the door opening sealing strip 400 in the Y direction. The orthographic projection of the inner surface 110 in the Z direction is arc-shaped, and the orthographic projection of the contact surface between the door opening sealing strip 400 and the inner surface 110 in the Z direction is also arc-shaped, with the arc arching towards the side closer to the interior of the passenger compartment. This design prevents water from accumulating at the connection between the first sealing edge 11 and the door opening sealing strip 400, thereby avoiding the problem of the first sealing edge 11 easily curling due to water accumulation.
[0049] For example, the thickness of the first sealing edge 11 is uniformly set.
[0050] For example, the contact surface between the door opening sealing strip 400 and the inner surface 110 is arc-shaped in the Z-direction, the arc step is ≤0.3mm, the radius of curvature of the arc is ≥2000R, and the curvature comb is continuous.
[0051] Combination Figure 1 and Figure 2 The present invention also proposes a vehicle front corner window assembly, including a front corner window 200 and the aforementioned vehicle front corner window sealing structure, wherein the aforementioned main body 100 is sealed to the front corner window 200.
[0052] In an example scheme, such as Figure 2 As shown, the vehicle front corner window assembly proposed in this utility model also includes an installation structure. The installation structure is used to install the main body 100 and the front corner window 200 onto the vehicle body. The installation structure includes a first mounting member 14, a second mounting member 15, and a third mounting member 16. The first mounting member 14 is located on the lower inner side of the front corner window 200. The second mounting member 15 is connected to the middle inner area of the functional member 101. The third mounting member 16 is connected to the lower inner end of the functional member 101. The first mounting member 14, the second mounting member 15, and the third mounting member 16 cooperate to achieve three-point positioning installation of the main body 100 and the front corner window 200.
[0053] For example, the height of the second mounting member 15 is approximately the same as the height of the first mounting member 14.
[0054] For example, the second mounting member 15 is configured to be adjustable in the Z-direction relative to the vehicle body, and the third mounting member 16 is configured to be adjustable in the X-direction relative to the vehicle body. This configuration avoids manufacturing errors and ensures the sealing performance between the upper end of the functional member 101 and the side sealing strip 300. During installation and fine-tuning, the upper end of the functional member 101 can only be fine-tuned in the Z-direction relative to the side sealing strip 300. Since the upper end of the functional member 101 and the side sealing strip 300 are in an interference fit, fine-tuning in the Z-direction will not affect the sealing performance between the functional member 101 and the side sealing strip 300, reducing the probability of water leakage. Fine-tuning in the X-direction is achieved through the third mounting member 16. Since the third mounting member 16 is located at the lower end of the functional member 101, it will not affect the sealing performance at the front corner window 200 during adjustment.
[0055] Optionally, the second mounting component 15 has a through hole with an adjustment margin in the Z direction relative to the vehicle body mounting point.
[0056] Optionally, the third mounting component 16 has a through hole with an adjustment allowance in the X direction relative to the vehicle body mounting point.
[0057] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
