Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a windshield drainage sealing strip for convertibles. Background Technology

[0002] Convertibles are vehicles with folding, openable roofs that can be mechanically closed or opened. To accommodate the unique roof structure of convertibles, the windshield typically uses a sealing strip with drainage channels. Traditional sealing strips have main and secondary drainage channels inside. Water accumulating above the windshield crossbeam and from the soft top enters these channels respectively. Because the sealing strip below the A-pillar corner and the two inner door panel sealing strips are usually interlocked, a gap inevitably forms at the connection point. Since both the sealing strip below the A-pillar corner and the two inner door panel sealing strips are through-type structures, these connections cannot effectively prevent water from overflowing, leading to leaks and affecting the overall waterproofing performance of the vehicle.

[0003] Therefore, there is an urgent need to design a drainage sealing strip to solve the above-mentioned problems in the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a windshield drainage sealing strip and a convertible, which has a simple structure, is easy to install, and can effectively solve the water leakage problem at the A-pillar corner of convertible cars.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Windshield drainage sealing strip, including:

[0007] The sealing strip body includes a main body section and a lower corner section. The lower corner section is fixedly connected to the main body section. The main body section is used to be fixedly installed on the side of the A-pillar of the car. The lower corner section is used to connect with the door panel sealing strip.

[0008] The water-blocking structure has a flow space inside the sealing strip body. The main body section is provided with a first water inlet and a drain outlet. The first water inlet is used to allow water to flow into the crossbeam of the front windshield. The drain outlet is located away from the door panel and at the lower edge of the front triangular window. The water-blocking structure is fixedly installed in the flow space between the main body section and the lower corner section, so that the interior of the sealing strip body forms a first flow channel located inside the main body section. The first water inlet is connected to the drain outlet through the first flow channel.

[0009] Preferably, a second water inlet is provided on the main body section, the second water inlet is connected to the first flow channel, and the second water inlet is used to allow water to flow into the roof after the vehicle is closed.

[0010] Preferably, the windshield drainage sealing strip further includes an upper corner section, which is fixedly connected to the main body section;

[0011] The upper section of the corner is provided with a first guide channel and a second guide channel. One end of the first guide channel is connected to the water collection channel of the upper crossbeam of the windshield, and the other end of the first guide channel is connected to the first water inlet. One end of the second guide channel is connected to the water collection channel of the roof after it is closed, and the other end of the second guide channel is connected to the second water inlet.

[0012] Preferably, the main body section is provided with a discharge trough, one end of which is positioned opposite the drain outlet, and the other end of which extends out of the front triangular window.

[0013] Preferably, the sealing strip body is made of EPDM rubber or thermoplastic vulcanized rubber.

[0014] Preferably, the water-blocking structure is made of EPDM rubber or thermoplastic vulcanized rubber.

[0015] Preferably, the main body segment and the lower corner segment are integrally formed.

[0016] Preferably, the lower section of the corner has a weight-reducing cavity, and the weight-reducing cavity and the first flow channel form the flow space.

[0017] Preferably, the water-blocking structure is disposed in the flow space of the main body section, and the water-blocking structure is integrally formed with the main body section.

[0018] A convertible includes a windshield, an A-pillar, and the aforementioned windshield drainage sealing strip. The A-pillar is located between the windshield and the front triangular window of the door panel, and the sealing strip body is fixedly connected to the A-pillar.

[0019] The beneficial effects of this utility model are as follows:

[0020] The windshield drainage sealing strip provided by this utility model includes a sealing strip body and a water-blocking structure. The sealing strip body includes a main body section and a lower corner section fixedly connected. Since the main body section is fixed to the side of the A-pillar, it can cooperate with the side window glass of the car door to achieve a sealing effect, preventing external water and dust from entering the vehicle through the side of the A-pillar. Since the lower corner section extends downwards to connect with the door panel sealing strip, it can seal the connection between the front quarter window and the door panel, thereby achieving waterproofing and dustproofing of the door panel. Furthermore, it integrates the windshield drainage sealing strip and the door panel sealing strip into a single structure, improving the overall performance of the windshield drainage sealing strip. Practicality: A water-blocking structure is incorporated into the flow space, creating a first flow channel within the sealing strip body. Since the first inlet of this channel faces the water guide groove on the upper crossbeam of the windshield, and the drain outlet is positioned away from the door panel at the lower edge of the front triangular window, water accumulated on the upper crossbeam of the windshield can flow into the first flow channel through the first inlet and ultimately drain out of the vehicle through the drain outlet. Because the first flow channel is located within the main body section, and the water-blocking structure is positioned in the flow space between the main body section and the lower corner section, water in the first flow channel is prevented from flowing into the lower corner section below, thus avoiding water leakage at the connection point between the door panel sealing strip and the lower corner section. This windshield drainage sealing strip has a simple structure, achieving a seal between the A-pillar and the side window glass, as well as between the front triangular window and the door panel. Furthermore, its internal water-blocking structure prevents accumulated water from flowing down to the sealing strip connection point and overflowing, thereby solving the water leakage problem at the A-pillar corner of convertibles.

[0021] The convertible provided by this utility model includes the aforementioned windshield drainage sealing strip. The windshield drainage sealing strip is fixedly connected to the A-pillar. While effectively draining water, its internal water-blocking structure can also prevent water from flowing down to the sealing strip connection position and overflowing, thereby solving the water leakage problem at the A-pillar corner of the convertible car. This greatly improves the waterproof performance of the convertible car and reduces the assembly difficulty. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0034] like Figures 1 to 4As shown, this utility model provides a windshield drainage sealing strip, which includes a sealing strip body 1 and a water-blocking structure 2. The sealing strip body 1 includes a main body section 11 and a lower corner section 12. The lower corner section 12 is fixedly connected to the main body section 11. The main body section 11 is used to be fixedly installed on the side of the A-pillar of the car, and the lower corner section 12 is used to connect with the door panel sealing strip. The sealing strip body 1 has a flow space inside. The main body section 11 is provided with a first water inlet 111 and a drain outlet 112. The first water inlet 111 is used to allow water accumulated on the upper crossbeam of the front windshield to flow in. The drain outlet 112 is located away from the door panel and at the lower edge of the front triangular window. The water-blocking structure 2 is fixedly installed in the flow space between the main body section 11 and the lower corner section 12, so that a first flow channel 113 is formed inside the main body section 11 inside the sealing strip body 1. The first water inlet 111 is connected to the drain outlet 112 through the first flow channel 113.

[0035] In this embodiment, since the main body segment 11 is fixed to the side of the A-pillar, it can cooperate with the side window glass of the door to achieve a sealing effect, preventing external water and dust from entering the vehicle through the side of the A-pillar. Since the lower corner segment 12 extends downward to connect with the door panel sealing strip, it can seal the connection between the front triangular window and the door panel, thereby achieving waterproofing and dustproofing of the door panel. Furthermore, it integrates the windshield drainage sealing strip with the door panel sealing strip into a single structure, improving the practicality of the windshield drainage sealing strip. A water-blocking structure 2 is provided in the flow space, forming a first flow channel 113 inside the sealing strip body 1. Because the first inlet 111 of the first flow channel 113 is positioned directly opposite the water guide groove of the upper crossbeam of the windshield, and the drain outlet 112 is positioned away from the door panel and below the front triangular window, water accumulated on the upper crossbeam of the windshield can flow into the first flow channel 113 through the first inlet 111 and finally be discharged outside the vehicle through the drain outlet 112. Since the first flow channel 113 is located in the main body section 11, and the water-blocking structure 2 is positioned in the flow space between the main body section 11 and the lower corner section 12, water in the first flow channel 113 can be prevented from flowing into the lower corner section 12 below, thus preventing water from overflowing from the connection point between the door panel sealing strip and the lower corner section 12 and causing leakage. This windshield drainage sealing strip has a simple structure, achieving a seal between the A-pillar and the side window glass, as well as between the front triangular window and the door panel. Furthermore, its internal water-blocking structure 2 prevents accumulated water from flowing down to the sealing strip connection point and overflowing, thereby solving the leakage problem at the A-pillar corner of the convertible.

[0036] In this embodiment, the main body segment 11 is divided into a column part and a corner part along the length direction. The two parts are connected in sequence and integrally formed. The column part is engaged with the side plate of the main body of the A-pillar of the vehicle body, and the corner part is engaged with the side of the front triangular window of the vehicle body. The first water inlet 111 is opened in the column part, the drain outlet 112 is opened in the corner part, and the lower corner segment 12 is connected to the lower end of the corner part.

[0037] To further improve the drainage capacity of the windshield drainage sealing strip, such as Figure 1 , Figure 3 as well as Figure 4 As shown, a second water inlet 114 is provided on the main body section 11. The second water inlet 114 is connected to the first flow channel 113. The second water inlet 114 is used to allow water to flow into the roof after the vehicle is closed. The connection position and connection method between the second water inlet 114 and the first flow channel 113 can be set according to the actual situation. In this embodiment, the main body section 11 has a second flow channel 116 inside. The second water inlet 114 is connected to the first flow channel 113 through the second flow channel 116. The specific connection position between the first flow channel 113 and the second flow channel 116 is not limited, as long as it is ensured that the water flow in the first flow channel 113 and the second flow channel 116 can continue to flow along the remaining part of the first flow channel 113 after merging and finally be discharged from the sealing strip body 1 through the drain outlet 112.

[0038] Furthermore, such as Figure 1 and Figure 3 As shown, the windshield drainage sealing strip also includes an upper corner section 3, which is fixedly connected to the main body section 11. The upper corner section 3 is provided with a first guide channel 31 and a second guide channel 32. One end of the first guide channel 31 is connected to the water accumulation channel on the upper crossbeam of the windshield, and the other end of the first guide channel 31 is connected to the first water inlet 111. One end of the second guide channel 32 is connected to the water accumulation channel on the closed roof, and the other end of the second guide channel 32 is connected to the second water inlet 114. The upper corner section 3 can collect the water accumulated on the upper crossbeam of the convertible windshield and the water accumulated on the open soft top and smoothly discharge it outside the vehicle through the first flow channel 113, thereby greatly improving the drainage capacity of the windshield drainage sealing strip.

[0039] In this embodiment, the upper corner section 3 is fixedly connected to the end of the main body section 11 away from the lower corner section 12. The upper corner section 3 is snapped onto the upper crossbeam of the windshield and is perpendicularly connected to the main body section 11. A semi-enclosed first guide channel 31 is provided on the upper corner section 3 along the length direction of the upper crossbeam of the windshield. Since the first guide channel 31 is connected to the water accumulation channel of the upper crossbeam of the windshield, the water in the water accumulation channel of the upper crossbeam will flow into the first inlet 111 along the first guide channel 31. An open second guide channel 32 is provided on the upper corner section 3 along the closing direction of the openable roof. When the roof is completely closed, the end of the roof will press against the upper corner section 3, thereby sealing the joint. The water accumulation channel of the roof is connected to the second guide channel 32 at this time, so the water in the roof will flow into the second inlet 114 along the second guide channel 32.

[0040] like Figure 2 and Figure 4As shown, a discharge groove 115 is provided on the main body section 11. One end of the discharge groove 115 is positioned directly opposite the drain outlet 112, and the other end of the discharge groove 115 extends out of the front triangular window. The discharge groove 115 can guide the water flowing out of the drain outlet 112 to a position outside the vehicle body away from the vehicle body for discharge, preventing the water from flowing back into the vehicle body under the action of wind force, thereby further improving the drainage capacity of the windshield drainage sealing strip. In this embodiment, a guide plate is provided on the main body section 11. The guide plate is connected to the main body section 11 below the drain outlet 112, and the other end of the guide plate extends out of the lower edge of the front triangular window. The surface of the guide plate is designed with a concave shape to form the discharge groove 115.

[0041] Specifically, the sealing strip body 1 is made of EPDM rubber or thermoplastic vulcanized rubber, and the water-blocking structure 2 is made of EPDM rubber or thermoplastic vulcanized rubber. Both EPDM rubber and thermoplastic vulcanized rubber are commonly used sealing strip materials in the field. In this embodiment, both the sealing strip body 1 and the water-blocking structure 2 are made of EPDM rubber and are integrally molded. For the sealing strip body 1, the main body section 11 and the lower corner section 12 are also integrally molded, which avoids the water seepage problem that is easy to occur at the joints of each structure, thereby further improving the sealing performance of the windshield drainage sealing strip.

[0042] The lower section 12 of the corner has a weight-reducing cavity inside. This cavity, together with the first flow channel 113, forms a flow space. The weight-reducing cavity can reduce the weight of the sealing strip body 1 and decrease material usage, thereby lowering the production cost of the windshield drainage sealing strip. In this embodiment, as... Figure 2 As shown, the water-blocking structure 2 is disposed in the flow space inside the sealing strip body 1. The water-blocking structure 2 divides the flow space into an independent and non-connected first flow channel 113 and a weight-reducing cavity. That is, the weight-reducing cavity is isolated from the first flow channel 113 by the water-blocking structure 2. When water flows into the first flow channel 113 through the first inlet 111 and the second inlet 114, it will continue to flow out of the drain outlet 112 under the guidance of the water-blocking structure 2. The specific shape of the water-blocking structure 2 is not limited here, as long as it can separate the first flow channel 113 and the weight-reducing cavity below to prevent water from flowing into the weight-reducing cavity.

[0043] In this embodiment, the lower corner section 12 is used to connect with the door panel sealing strip, and the two are connected by a plug-in connection. The door panel sealing strip has a water groove inside. The water-blocking structure 2 is set in the flow space of the main body section 11, and the water-blocking structure 2 is integrally formed with the main body section 11, so as to effectively prevent water from entering the connection position between the lower corner section 12 and the door panel sealing strip.

[0044] This embodiment also provides a convertible vehicle, which includes a windshield, an A-pillar, and the aforementioned windshield drainage sealing strip. The A-pillar is located between the windshield and the front triangular window of the door panel, and the sealing strip body 1 is fixedly connected to the A-pillar. In this embodiment, the windshield drainage sealing strip is fixedly connected to the A-pillar, which can effectively drain water while its internal water-blocking structure 2 can prevent water from flowing down to the connection position between the lower section 12 of the corner and the door panel sealing strip and overflowing, thereby solving the water leakage problem at the corner of the A-pillar of the convertible vehicle and greatly improving the waterproof performance of the convertible vehicle.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
