Description

Technical Field

[0001] This utility model relates to the field of automotive sealing strip technology, specifically an exterior structure for automotive sealing strips. Background Technology

[0002] The exterior sealing strip for convertible cars is specifically designed around the opening and closing characteristics and sealing requirements of convertibles. The main body includes a multi-layered nested hollow sealing lip, which can elastically deform to fit tightly against the roof frame and the edge of the tarpaulin when the convertible is closed, forming multiple barriers. The installation area has barbed grooves or metal strips that can be firmly locked into the pre-reserved slots in the body to prevent them from falling off due to vibration during driving. The side that connects to the tarpaulin features a gradient thin edge design to reduce obstruction to the folding of the tarpaulin, while the other side extends with an arc-shaped decorative edge to cover the joint between the body and the sealing strip. Some sealing strips also integrate drainage channels, which can guide a small amount of rainwater to the external drainage holes when it seeps in. At the same time, the corners use an integrated curved structure to avoid dead corners at the joints, balancing sealing performance and structural adaptability.

[0003] Because the entire circumference of the car body is curved, the existing sealing strip trim can only be arranged in sections. However, there are gaps between the sections. After being assembled into the car body, there are surface differences at the joints of the sections, resulting in poor appearance. In addition, there are gaps between the sections. When the car is rained on, water can seep into the car through the gaps between the sections, causing the car to be not waterproof and sealed properly.

[0004] Based on this, an exterior structure for automotive sealing strips is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this utility model is to provide an exterior sealing strip structure for automobiles, so as to solve the problem in the background art that the exterior sealing strip can only be arranged in segments because the entire circumference of the car body is curved.

The exterior sealing strip structure formed by the skeleton and the body is adapted to convertible automobiles.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the frame and the main body are heat-set to meet different vehicle body structures.

[0008] In one alternative: the skeleton is made of PP, and the main body is made of TPV.

[0009] In one alternative: a coding area is provided on one side of the skeleton.

[0010] In one alternative: the frame and the main body form a sealing strip exterior trim piece that is mounted on the exterior of the convertible.

[0011] In one alternative: the convertible is topped with a tarpaulin and sheet metal.

[0012] In one alternative: the sheet metal is externally engaged with a U-shaped buckle, and the frame is mounted on the outside of the U-shaped buckle.

[0013] In one alternative: the main body is placed over a tarpaulin.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adopts a structure combining TPV and PP, and uses heat setting to meet different vehicle body structures, forming a stable and reliable positioning structure. Its shape and size are mainly determined according to the vehicle body structure, and can be round, square or other shapes. The integrated cross-section structure can be bent into different shapes without segmentation. The exterior trim is integrated, eliminating the defects of segment gaps and more effectively preventing rainwater, dust and noise from entering the vehicle.

[0015] 2. The integrated sealing strip exterior structure of this utility model can reduce surface defects caused by product segmentation and solve the adverse effects of appearance defects on the overall product. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-6 As shown, an exterior sealing strip structure for automobiles includes a frame 1, with a main body 2 integrally formed on the outside of the frame 1. An installation groove 8 is formed inside the frame 1, and protrusions 3 are provided on the inner wall of the installation groove 8. The exterior sealing strip structure formed by the frame 1 and the main body 2 is adapted to convertible automobiles. The frame 1 and the main body 2 are heat-set to meet different vehicle body structures. The frame 1 is made of PP, and the main body 2 is made of TPV. A coding area 7 is provided on one side of the frame 1.

[0025] In this embodiment, the structure is simple, using a combination of TPV and PP. It adopts a heat-setting method to meet different vehicle body structures, forming a stable and reliable positioning structure. Its shape and size are mainly determined by the vehicle body structure and can be circular, square, or other shapes. The integrated cross-section structure can be bent into different shapes without segmentation. The integrated exterior trim eliminates the defects of segment gaps and more effectively prevents rainwater, dust, and noise from entering the vehicle. The integrated sealing strip exterior trim structure can reduce surface defects caused by product segmentation and solve the adverse effects of appearance defects on the overall product.

[0026] In one embodiment, such as Figure 1 and Figure 3 As shown, the sealing strip exterior trim consisting of the frame 1 and the main body 2 is installed on the exterior of the convertible. The top of the convertible is provided with a tarpaulin 4 and a sheet metal 5. A U-shaped buckle 6 is fastened to the outside of the sheet metal 5. The frame 1 is installed outside the U-shaped buckle 6, and the main body 2 is placed on top of the tarpaulin 4. The frame 1 is connected to the sheet metal 5 of the convertible through the cooperation of the U-shaped buckle 6, which facilitates the rotation or disassembly of the sealing strip trim and does not cause wear to the sheet metal 5 during replacement, thus improving practicality.

[0027] The above embodiment discloses an automotive sealing strip exterior component structure, wherein the skeleton 1 and the main body 2 are simultaneously composite extruded. After composite extrusion, the required length is cut according to the requirements, and then the cut sealing strip exterior component is placed on a car body-like bending mold for heat setting. After setting, the product manufacturing is completed. It adopts a structure combining TPV and PP, and uses heat setting to meet different car body structures, forming a stable and reliable positioning structure. Its shape and size are mainly determined according to the car body structure, and can be round, square, or other shapes. The integrated cross-section structure can be bent into different shapes without segmentation. The integrated exterior component eliminates the defects of segment gaps, and more effectively prevents rainwater, dust, and noise from entering the car. The integrated sealing strip exterior component structure can reduce the surface difference defects caused by product segmentation and solve the adverse effects of appearance defects on the overall product.

[0028] The frame 1 is connected to the sheet metal 5 of the convertible car by the U-shaped buckle 6, which makes it easy to rotate or remove the sealing strip trim, and will not cause wear to the sheet metal 5 during the replacement process, thus improving practicality.
