Description

Technical Field

[0001] This utility model relates to the field of automotive sealing strip technology, specifically to a sealing strip for automotive trunks. Background Technology

[0002] Cars are a common means of transportation and have entered ordinary people's households.

[0003] The trunk of a car is equipped with a rubber strip that is snapped and fixed to the vehicle's connecting parts. The sealing strip and sealing lip of the rubber strip contact and abut against the vehicle's connecting parts. When the car's trunk door is closed, it contacts and abuts against the cut surface of the rubber strip, making the car body airtight, thereby achieving the effects of waterproofing and sound insulation.

[0004] The inventors of this application have discovered that, during installation, existing sealing strips tend to tilt outwards due to various reasons, causing the door sealing surface to extend beyond the smallest part of the cross-section sealing surface. During high-pressure car washing, water can enter the vehicle body from between the door sealing surface and the cross-section. Furthermore, the tilted sealing strip can block the vehicle's drainage holes. During the rainy season in May, water accumulated in the cavity of the sealing strip cannot drain from the drainage holes and will enter the vehicle body. In other words, the tilting of the sealing strip affects the vehicle's sealing performance, causing water to enter the vehicle. Summary of the Invention

[0005] The purpose of this invention is to provide a sealing strip for automobile trunks to solve the problems mentioned in the background art.

[0006] This utility model provides a sealing strip for a car trunk, comprising: an interlocking portion and a cross-sectional portion;

[0007] The fitting part is provided with a U-shaped groove;

[0008] The fitting part is provided with sealing strips on both sides of the inner wall of the U-shaped groove. The sealing strips on both sides are arranged in a trumpet shape. The fitting part is provided with sealing lips on the outer side of the U-shaped groove. The U-shaped groove is used to engage with the vehicle connection part. The sealing strips and the sealing lips are used to abut against the vehicle connection part.

[0009] The cross-section is connected to the bottom wall of the U-shaped groove and is used to abut against the trunk door to seal the vehicle.

[0010] The fitting part has a reinforcing rib on the sealing strip near the lower end of the outer side of the vehicle. The reinforcing rib is used to abut against the vehicle connection part to support the sealing strip and prevent the sealing strip from tilting to the outside of the vehicle.

[0011] Based on the above solution, the sealing strip for a car trunk of this utility model, by setting an interlocking part and a cross-section, includes an interlocking part with a U-shaped groove, sealing strips on both inner walls of the U-shaped groove (the sealing strips on both sides are flared), a sealing lip on the outer wall of the U-shaped groove, and a cross-section connected to the bottom wall of the U-shaped groove. The interlocking part has reinforcing ribs on the sealing strip near the lower outer end of the vehicle, which abut against the vehicle connection to provide support for the sealing strip. The sealing strip for a car trunk of this utility model is installed in a ring shape in the trunk of the car body. The U-shaped groove of the interlocking part engages with the vehicle connection, completing the installation and fixation of the sealing strip on the car body. When the fitting part is inserted, the reinforcing rib of the fitting part abuts against the vehicle connection part, forming support for the sealing strip, thereby preventing the fitting part and the cross-section of the sealing strip from tilting to the outside of the vehicle. This ensures that the door sealing surface does not exceed the minimum part of the cross-section sealing surface, and the sealing strip does not block the vehicle body drainage hole, thus enhancing the vehicle's sealing performance. During high-pressure car washes and the negative pressure rainy season in May, water will not enter the vehicle body.

[0012] In one feasible solution, the reinforcing rib has a circular cross-section and is connected to the sealing strip by a connecting rib.

[0013] In one feasible solution, the reinforcing rib has multiple protrusions spaced apart on its circumferential sidewall.

[0014] In one feasible solution, the height of the plurality of protrusions gradually increases from the side away from the vehicle connection to the side closer to the vehicle connection.

[0015] In one feasible embodiment, the angle between the extension direction of the highest protrusion and the insertion direction relative to the vehicle connection is an acute angle.

[0016] In one feasible solution, the sidewalls and bottomwalls of the U-shaped groove are provided with core metal.

[0017] In one feasible solution, the bottom wall of the U-shaped groove is provided with a high-soft sealing protrusion.

[0018] In one feasible solution, the reinforcing rib is disposed on a sealing strip located at the bottom of the vehicle's trunk. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0037] As described in the background section of this application, participating Figure 1 As shown, a sealing strip 100 is provided at the trunk of the car. The strip is snapped and fixed to the vehicle connection part 210. The sealing strip and sealing lip of the strip contact and abut against the vehicle connection part. When the trunk door is closed, it contacts and abuts against the cross-section of the strip, so that the car body is sealed to achieve the effects of waterproofing and sound insulation.

[0038] The inventors of this application discovered that, during installation, the existing sealing strip 100 tends to tilt outwards due to various reasons, causing the door sealing surface to extend beyond the smallest part of the sealing surface at the strip's cross-section. During high-pressure car washing, water can enter the vehicle body from between the door sealing surface and the cross-section (e.g., during a high-pressure wash).Figure 3 and Figure 4 (As shown); moreover, the sealing lip of the tilted sealing strip can block the vehicle's drainage holes. During the rainy season in May, water accumulated in the cavity of the sealing strip cannot drain out of the drainage holes and will enter the vehicle body (as shown). Figure 2 As shown in the image, tilted sealing strips can affect the vehicle's sealing performance, causing water to enter the vehicle.

[0039] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

Figure 6 As described in the embodiments of this utility model Figure 5 A magnified view of a portion of the image. Figure 7 This is a schematic diagram of the assembly of the sealing strip in an embodiment of the present utility model. Figure 8 For the sealing strip in the embodiments of this utility model Figure 1 A cross-sectional view along the A′-A′ direction. Figure 9 For the sealing strip in the embodiments of this utility model Figure 1 A cross-sectional view along the B′-B′ direction. Figure 10 This is a schematic diagram illustrating the installation effect of the sealing strip in an embodiment of this utility model. Figure 11 This is a schematic diagram of the installation of the sealing strip in an embodiment of the present invention.

[0041] like Figures 5 to 11 As shown, the sealing strip for the car trunk in this embodiment is installed in a ring shape at the trunk of the car body. The sealing strip includes: an interlocking part 1 and a cross-sectional part 2.

[0042] The fitting part 1 and the cross-section part 2 of the sealing strip are an integral structure.

[0043] The longitudinal section of the fitting part 1 is U-shaped and has a U-shaped groove.

[0044] The fitting part 1 has sealing strips 11 on both sides of the inner wall of the U-shaped groove. The sealing strips 11 on both sides are arranged in a trumpet shape. The tail end of the sealing strip 11 extends toward the bottom side of the U-shaped groove. The fitting part 1 has a sealing lip 101 on the side wall of the U-shaped groove near the outside of the vehicle.

[0045] The cross-section 2 is connected to the bottom wall of the U-shaped groove of the fitting part 1. The cross-section 2 is a hollow structure with a cavity 21 inside.

[0046] The fitting part 1 of the sealing strip has a reinforcing rib 12 on the sealing strip 11 at the lower end of the outer side of the vehicle. The reinforcing rib 12 of the fitting part 1 is used to abut against the vehicle connection part 210 to support the sealing strip, thereby preventing the fitting part 1 and the cross-section 2 of the sealing strip from tilting outwards.

[0047] In this embodiment, the sealing strip for the car trunk is installed in a ring shape in the trunk of the vehicle. The U-shaped groove of the fitting part 1 engages with the vehicle connection part 210, thus completing the installation and fixation of the sealing strip on the vehicle body. When the fitting part 1 is inserted, the reinforcing rib 12 of the fitting part 1 abuts against the vehicle connection part 210, providing support for the sealing strip and preventing the fitting part and the cross-section of the sealing strip from tilting outwards towards the outside of the vehicle, thereby enhancing the vehicle's sealing performance.

[0048] As can be seen from the above, the sealing strip for the car trunk in this embodiment features an interlocking part and a cross-section. The interlocking part has a U-shaped groove, and sealing strips are provided on the inner walls of both sides of the U-shaped groove. The sealing strips on both sides are flared. The interlocking part has a sealing lip on the outer wall of the U-shaped groove, and the cross-section is connected to the bottom wall of the U-shaped groove. The interlocking part has reinforcing ribs on the sealing strip near the lower outer end of the vehicle. These reinforcing ribs abut against the vehicle connection part to support the sealing strip. The sealing strip for the car trunk in this embodiment is installed in a ring shape in the trunk of the car body. The U-shaped groove of the interlocking part engages with the vehicle connection part, completing the installation and fixation of the sealing strip on the car body. When the fitting part is inserted, the reinforcing rib of the fitting part abuts against the vehicle connection part, forming support for the sealing strip, thereby preventing the fitting part and the cross-section of the sealing strip from tilting to the outside of the vehicle. This ensures that the door sealing surface does not exceed the minimum part of the cross-section sealing surface, and the sealing strip does not block the vehicle body drainage hole, thus enhancing the vehicle's sealing performance. During high-pressure car washes and the negative pressure rainy season in May, water will not enter the vehicle body.

[0049] Optional, such as Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the sealing strip for the car trunk has a circular longitudinal section for the reinforcing rib 12. The reinforcing rib 12 is connected to the sealing strip 11 at the bottom of the fitting part 1 by the connecting rib 13. When the reinforcing rib 12 abuts against the vehicle connection part 210, it bends and rotates towards the hollow side inside.

[0050] Furthermore, in this embodiment, the sealing strip for the car trunk has multiple protrusions 121 spaced apart on the circumferential sidewall of the reinforcing rib 12. When the protrusions 121 come into contact with the vehicle connection part 210, the reinforcing rib 12 flexes and rotates toward the hollow side of the U-shaped groove.

[0051] Furthermore, in this embodiment, the height of the multiple protrusions 121 on the reinforcing rib 12 of the sealing strip for the car trunk gradually increases from the side away from the vehicle connection part 210 to the side closer to the vehicle connection part 210. That is, the protrusion 121 with the maximum height is located in the middle of the hollow part, close to the vehicle connection part 210. This makes it easy for the reinforcing rib 12 to be locked onto the vehicle connection part 210 when the sealing strip is installed, even if the insertion position of the sealing strip is close to the interior side.

[0052] Furthermore, in this embodiment, the angle between the extension direction of the highest protrusion 121 on the reinforcing rib 12 and the insertion direction relative to the vehicle connection part 210 of the sealing strip for the car trunk is an acute angle, which makes it easier for the reinforcing rib 12 to be locked by the vehicle connection part 210.

[0053] Optionally, in this embodiment, the sealing strip for the car trunk has a high-softness sealing protrusion 14 on the bottom wall of the U-shaped groove at the fitting part 1. When the sealing strip is assembled, the high-softness sealing protrusion 14 abuts against the top of the vehicle connection part 210, increasing the vehicle's sealing performance.

[0054] Optionally, in this embodiment, the sealing strip for the car trunk has a core 15 in the side and bottom walls of the U-shaped groove of the fitting part 1 to increase the rigidity and strength of the fitting part 1, thereby enhancing the clamping force of the sealing strip on the vehicle.

[0055] Furthermore, such as Figure 11 As shown, in this embodiment, the sealing strip for the car trunk is installed in a ring shape at the trunk of the vehicle. The reinforcing rib 12 is provided on the sealing strip 100 located at the bottom of the trunk (solid line position). No reinforcing ribs are provided on the sealing strip 100 on the sides and top of the trunk (dashed line position).

[0056] Since there will be no water accumulation on the sides and top of the vehicle's trunk, there is no need to install reinforcing ribs on the sealing strips 100 on the sides and top of the vehicle's trunk.

[0057] This utility model discloses a sealing strip for a car trunk, which is installed in a ring shape in the trunk of a car. When the fitting part is inserted into the vehicle connection part, the protrusion of the reinforcing rib contacts the vehicle connection part and causes the reinforcing rib to bend and rotate inward towards the vehicle, clamping between the vehicle connection part and the sealing lip. The reinforcing rib provides support for the sealing strip, preventing the fitting part and the cut surface from tilting outward towards the vehicle, thus preventing the vehicle's drainage holes from being blocked. Figure 8 (as shown in the diagram), and the minimum part of the cross-sectional sealing surface will not extend beyond the vehicle sealing surface ( Figure 9 and Figure 10 (As shown in the image), it enhances the vehicle's sealing, preventing water from entering the vehicle during the rainy season in May under negative pressure, as well as during high-pressure car washes.

[0058] In this utility model, unless otherwise explicitly specified and limited, the first feature being "on" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium.

[0059] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
