Description

Technical Field

[0001] This utility model belongs to the field of external water cutting technology, specifically relating to a novel concealed external water cutting structure. Background Technology

[0002] In frameless automotive design, concealed external water-cut lips are a common window sealing structure widely used around the perimeter of the window glass. However, this design has encountered some technical challenges in practical applications, particularly regarding window deformation after the window is raised and wiper performance.

[0003] Existing concealed outer water-resistant lip designs are typically quite simple and lack sufficient support structure. When the window is raised, the outer water-resistant lip, due to its inherent elasticity and flexibility, often deforms. This deformation not only affects the window's sealing performance but also reduces its wiping performance. When rainwater or other liquids fall on the window, the outer water-resistant lip may not be able to effectively remove the water, leading to water residue or seepage into the vehicle.

[0004] Therefore, a new type of concealed external windshield shear structure is needed to solve the problems of existing concealed external windshield shear lips lacking support structure and having poor wiping performance after the window is raised and deformed. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a novel concealed external water-cutting structure, which solves the problems of the existing concealed external water-cutting lip lacking a support structure and having poor water-wiping performance after the car window is raised and deformed.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A novel concealed external water deflector structure includes a support member connected to a sheet metal part and an external water deflector body; the support member is disposed on the side of the external water deflector body away from the vehicle window, and a fixing lip is fitted on the upper part of the external water deflector body, the upper part of the fixing lip abutting against the support member.

[0008] The lower part of the fixed lip is connected to the movable lip. The end of the movable lip that connects to the fixed lip is an arc-shaped part, and the arc-shaped part and the fixed lip form an upward-opening V-shaped deformed space.

[0009] Preferably, the end of the movable lip that connects to the outer water-cutting body is a straight section, and the straight section and the arc-shaped section form a V-shaped movable space that faces away from the window and opens downwards.

[0010] Preferably, the length of the arc-shaped portion is less than the length of the straight portion.

[0011] Preferably, the lower part of the outer water-cutting body is further provided with a lower lip, which is located below the straight part and forms an upward-opening support space with the straight part.

[0012] Preferably, the lower lip and the side of the straight portion that contacts the window are provided with a velvet strip, and the lower lip and the movable lip are made of soft rubber.

[0013] Preferably, it also includes a stabilizing strip, which is adhered to the outer water-cutting body by tape, and the upper part of the stabilizing strip abuts against the lower part of the fixed lip; the other end of the movable lip is connected to the lower part of the stabilizing strip.

[0014] Preferably, the stabilizing strip is made of rigid plastic.

[0015] The beneficial effects of this utility model are as follows:

[0016] This application provides a stable support foundation for the outer water-cutting structure by setting a support member on the side of the outer water-cutting body away from the window, which abuts against the upper part of the fixed lip. This design effectively solves the problem of deformation of the outer water-cutting lip due to lack of support after the window is raised, ensuring the stability and reliability of the outer water-cutting structure when the window is raised. The movable lip connected to the lower part of the fixed lip, through the upward-opening V-shaped deformation space formed between the arc-shaped part and the fixed lip, can flexibly adapt to the slight deformation of the window edge. This design allows the movable lip to fit tightly against the window edge, maintaining good water-wiping performance even when the window is raised and slightly deformed, effectively preventing rainwater from seeping into the vehicle.

[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 novel concealed external waterstop structure includes a support member 1 connected to a sheet metal part and an external waterstop body 2. The support member 1 is located on the side of the external waterstop body 2 away from the window. A fixing lip 3 is fitted onto the upper part of the external waterstop body 2, and the upper part of the fixing lip 3 abuts against the support member 1. The support member 1 is fixed to the vehicle sheet metal part and located on the side of the external waterstop body 2 away from the window, ensuring that the external waterstop body 2 has a stable supporting base when the window is raised, reducing the deformation of the external waterstop body 2 itself caused by the deformation of the window, thereby maintaining good sealing performance.

[0023] The lower part of the fixed lip 3 is connected to a movable lip 4. The end of the movable lip 4 connected to the fixed lip 3 is an arc-shaped part 41, forming an upward-opening V-shaped deformation space 81 between the arc-shaped part 41 and the fixed lip 3. The support is located on the side of the outer water-cutting body 2 away from the window, ensuring that the overall structure of the outer water-cutting body 2 remains stable and not easily deformed even when the window is raised. The upper part of the fixed lip 3 abuts against the support 1, providing a stable support base for the fixed lip 3. The movable lip 4 has a certain elastic deformation when the window is raised, deforming closer to the fixed lip 3, while the fixed lip 3 is supported by the support 1. This design allows the movable lip 4 to slow down as it approaches deformation, enabling the V-shaped deformation space 81 to gradually adapt to the contact deformation between the movable lip 4 and the car window. This allows the movable lip 4 to better fit the car window glass. At the same time, it ensures that when subjected to external pressure (such as rain), the fixed lip 3 provides support for the movable lip 4, maintaining close contact with the car window. When the car window is raised, the structural stability of the outer water-cutting body 2 ensures that the lip can fit evenly and tightly against the car window glass. The V-shaped deformation space 81 design of the movable lip 4 allows the lip to more effectively guide the water flow when impacted by water, reducing water stagnation and splashing, thereby improving the wiping performance.

[0024] In summary, this application provides a stable support foundation for the outer water-cutting structure by setting a support member 1 on the side of the outer water-cutting body 2 away from the window and abutting against the upper part of the fixed lip 3. This design effectively solves the problem of deformation of the outer water-cutting lip due to lack of support after the window is raised, ensuring the stability and reliability of the outer water-cutting structure when the window is raised. The movable lip 4 connected to the lower part of the fixed lip 3 can flexibly adapt to the slight deformation of the window edge through the upward-opening V-shaped deformation space 81 formed between the arc-shaped part 41 and the fixed lip 3. This design allows the movable lip 4 to fit tightly against the window edge, maintaining good water-wiping performance even when the window is raised and slightly deformed, effectively preventing rainwater from seeping into the vehicle.

[0025] In one embodiment, the end of the movable lip 4 connected to the outer water-cutting body 2 is a straight section 42, and the straight section 42 and the arc-shaped section 41 form a V-shaped movable space 82 that is away from the side of the car window and opens downward.

[0026] In one embodiment, the length of the arc-shaped portion 41 is less than the length of the straight portion 42, so that when the window glass is raised and lowered and abuts against the movable lip 4, the straight portion 42 abuts against the window and bears the main force, which is then transmitted to the arc-shaped portion 41. In this way, the length of the arc-shaped portion 41 is smaller, so that the force transmitted from the straight portion 42 to the arc-shaped portion 41 is less weakened, so that the arc-shaped portion 41 is deformed by the abutment under the action of the straight portion 42. In addition, there is a support member 1 on the side of the arc-shaped portion 41 near the fixed lip 3, so that the support force at both ends of the arc-shaped portion 41 is sufficient when it abuts and deforms, preventing the straight portion 42 from deviating from the window, thereby further enhancing the window's water-retaining capacity.

[0027] In one embodiment, the lower part of the outer water-cutting body 2 is further provided with a lower lip 5. The lower lip 5 is located below the straight portion 42 and forms an upward-opening support space 83 with the straight portion 42. The lower lip 5 is located below the straight portion 42 and is tightly connected to the straight portion 42, together forming an upward-opening support space 83. This support space 83 provides additional support for the movable lip 4, especially when the window is raised or subjected to external pressure, ensuring that the movable lip 4 maintains a stable shape and is not prone to excessive deformation. The addition of the lower lip 5 significantly enhances the overall structural stability of the outer water-cutting body 2. As an additional support point, it shares the pressure on the movable lip 4 when the window is raised, thereby reducing the risk of wear and damage to the movable lip 4. At the same time, the lower lip 5 also improves the resistance of the outer water-cutting body 2 to external impacts and extends its service life.

[0028] In one embodiment, a velour strip 6 is provided on the side of the lower lip 5 and the straight portion 42 that contacts the window. The lower lip 5 and the movable lip 4 are made of soft rubber. The velour strip 6 is soft and has a certain degree of elasticity, which can form a tight fit with the window glass, effectively reducing the penetration of rainwater, dust and other impurities, and improving the sealing performance. At the same time, the velour strip 6 can also reduce the noise when the window is raised and lowered, providing a quieter driving environment. Furthermore, when the window is raised and lowered, the movable lip 4 and the lower lip 5 deform downward due to the friction of the window.

[0029] In one embodiment, a stabilizing strip 7 is also included. The stabilizing strip 7 is adhered to the outer water-cutting body 2 by adhesive tape, and the upper part of the stabilizing strip 7 abuts against the lower part of the fixed lip 3. The other end of the movable lip 4 is connected to the lower part of the stabilizing strip 7. The stabilizing strip 7 is adhered to the outer water-cutting body 2 by adhesive tape, enhancing the stability of the entire outer water-cutting structure. As an additional support structure, the stabilizing strip 7 can resist deformation caused by the window being raised or external pressure, ensuring that the movable lip 4 and the fixed lip 3 maintain the correct position and shape. The upper part of the stabilizing strip 7 abuts against the lower part of the fixed lip 3, and this connection method helps to optimize stress distribution. When the window is raised, the fixed lip 3 is subjected to pressure from the window glass, and the presence of the stabilizing strip 7 can disperse some of the pressure to the outer water-cutting body 2 and the stabilizing strip 7 itself, reducing the deformation and wear of the fixed lip 3.

[0030] In one embodiment, the stabilizing strip 7 is made of rigid plastic, which has high strength and rigidity and can withstand the pressure generated when the window is raised, ensuring that the stabilizing strip 7 is not easily deformed or damaged when subjected to external forces, thus helping to maintain the overall stability and reliability of the external water-cutting structure.

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.
