Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a frameless door pillar assembly and a vehicle having the same. Background Technology

[0002] With the development of automobiles, consumers have increasingly higher requirements for car appearance, and whether a car's exterior is fashionable has become an important factor influencing car purchases. A clean and smooth appearance is an important element of a fashionable look. Therefore, frameless doors with a smooth and flowing appearance are becoming increasingly popular among consumers. Traditional frameless doors consist of the door glass, door pillar trim, and a sealing strip between the door glass and the body pillar trim above the waistline. Because the sealing strip is gray and has raised features, there is a noticeable color difference between the sealing strip and the surrounding parts, resulting in an abrupt appearance. This not only affects the color consistency of the door side appearance but also the consistency of the overall design.

[0003] To address this issue while ensuring a compatible sealing system, concealing the sealing strip is a crucial method for improving the side appearance of frameless doors. Currently, integrated frameless door sealing strips in the industry can achieve a smooth and clean side profile without being exposed, but they are slightly inferior in terms of water management and NVH performance (noise, vibration, and harshness). Therefore, resolving the rubber water management and NVH performance issues of integrated frameless door sealing systems has become a pressing challenge for the industry. Summary of the Invention

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following is for reference. Figure 1 A frameless door pillar assembly 100 according to a first aspect embodiment of the present invention is described.

[0031] According to a first aspect embodiment of the present invention, the frameless door pillar assembly 100, such as Figure 1 As shown, the frameless door pillar assembly 100 includes a body pillar 10 and a sealing element 20. The sealing element 20 is an integral part and includes a fixing part 21, a first sealing edge 22 and a second sealing edge 23. The fixing part 21 is fixedly connected to the body pillar 10. The first sealing edge 22 and the second sealing edge 23 are both connected to the fixing part 21 and are spaced apart in the front-rear direction. The first sealing edge 22 and the second sealing edge 23 are both adapted to abut against the door glass 200 to seal the gap between the door glass 200 and the body pillar 10. The first sealing edge 22, the second sealing edge 23 and the fixing part 21 cooperate to define a drainage cavity that is recessed towards the inside of the body.

[0032] The body pillar 10 primarily provides support for the vehicle and serves as a door frame. The seal 20, made of a flexible and corrosion-resistant material, seals the gap between the door glass 200 and the body pillar 10; for example, the seal 20 can be made of EPDM material. The seal 20 is a single, integrated piece, securely connected, easy to install, and relatively easy to conceal, allowing for a smooth and clean appearance on the vehicle's sides. The fixing part 21 of the seal 20 is fixedly connected to the body pillar 10, so that the seal 20 is fixed to the body, thereby preventing the seal 20 from shifting due to friction and ensuring the sealing performance of the seal 20; the first sealing edge 22 abuts against the end of the door glass 200 near the body pillar 10, and the first sealing edge 22 is lower than the exterior surface of the body; the second sealing edge 23 abuts against the inner side of the end of the door glass 200 near the body pillar 10; the first sealing edge 22 and the second sealing edge 23 both abut against and seal with the door glass 200 and the body pillar 10, that is, forming a double seal and compression for the door glass 200 and the body pillar 10, thereby increasing the sealing performance of the vehicle and ensuring the excellent NVH performance of the window.

[0033] The drainage chamber is mainly used to drain some of the rainwater from the roof and the rainwater that has passed over the first sealing edge 22, preventing rainwater from entering the vehicle and damaging the vehicle body. At the same time, since one end of the first sealing edge 22 abuts against the end of the door glass 200 and one end of the second sealing edge 23 abuts against the inner side of the door glass 200 near the end, the first sealing edge 22 and the second sealing edge 23 are arranged at intervals, forming a certain distance. The other ends of the first sealing edge 22 and the second sealing edge 23 are respectively connected to the fixing part 21, and the fixing part 21 is fixedly connected to the body pillar 10. A certain distance is formed between the body pillar 10 and the door glass 200, thus defining a relatively large chamber between the first sealing edge 22, the second sealing edge 23 and the fixing part 21. Therefore, using this chamber as a drainage chamber can increase the vehicle's drainage effect and improve the vehicle's water management performance.

[0034] When the car door is closed and the door glass 200 is fully raised, the first sealing edge 22 and the second sealing edge 23 abut against the door glass 200 to fill and seal the gap between the vehicle body pillar 10 and the door glass 200, thus sealing and soundproofing the vehicle. When the car door is opened or the door glass 200 is lowered, the sealing strip appears as a single piece, for example... Figure 1 As shown, the presence of only one ridge line can make the vehicle's appearance more streamlined.

[0035] According to an embodiment of the present invention, the frameless door pillar assembly 100, through the integrated sealing element 20, can make the side appearance of the vehicle smoother and cleaner; at the same time, the first sealing edge 22 and the second sealing edge 23 provided by the sealing element 20 both abut against the door glass 200 and the body pillar 10, which can increase the sealing performance of the vehicle and ensure the excellent NVH performance of the window; in addition, the cavity defined by the first sealing edge 22, the second sealing edge 23 and the fixing part 21 serves as a drainage cavity, which can increase the volume of the drainage cavity, thereby increasing the drainage effect of the vehicle and ensuring good water management performance of the vehicle.

[0036] According to some embodiments of the present invention, such as Figure 1 As shown, the first sealing edge 22 and the second sealing edge 23 are respectively arranged at both ends of the fixing part 21 in the front-rear direction, and in the front-rear direction (e.g.) Figure 1 As shown in the front-to-back direction, the first sealing edge 22 and the second sealing edge 23 extend toward each other, thereby increasing the space defined by the first sealing edge 22, the second sealing edge 23 and the fixing part 21, which in turn increases the space of the drainage cavity, increases the drainage effect, and ensures good water management performance of the vehicle.

[0037] According to some embodiments of the present invention, such as Figure 1As shown, the first sealing edge 22 extends forward and backward, with its rear end connected to the fixing part 21. The front end of the first sealing edge 22 extends along an arc that bends forward and towards the inner side of the vehicle body. The front end of the second sealing edge 23 is connected to the fixing part 21, and its rear end extends along a convex arc that protrudes backward and towards the outer side of the vehicle body. The first sealing edge 22 and the second sealing edge 23 abut against the door glass 200 with convex arc surfaces, which increases the contact area between the seal 20 and the door glass 200, thereby increasing the vehicle's sealing effect and the window's vibration damping and noise reduction effects. Simultaneously, because the convex arc surface maintains its original state under its own inertia, it increases the compressive force on the door glass 200, thus allowing the seal 20 to fit more tightly against the door glass 200, improving the vehicle's sealing effect. According to some embodiments of the present invention, such as... Figure 1 As shown, the sealing element 20 further includes a connecting portion 24, located between the first sealing edge 22 and the second sealing edge 23. One end of the connecting portion 24 is connected to the fixing portion 21, and the other end of the connecting portion 24 is connected to the end of the second sealing edge 23 facing the first sealing edge 22. The connecting portion 24, the second sealing edge 23, and the fixing portion 21 cooperate to define a cavity, and the free ends of the first sealing edge 22, the fixing portion 21, the connecting portion 24, and the second sealing edge 23 cooperate to define a drainage cavity. The connecting portion 24 provides support for the second sealing edge 23, increasing the contact strength between the second sealing edge 23 and the door glass 200, thereby increasing the sealing effect of the sealing element 20. Simultaneously, the cavity defined by the connecting portion 24, the second sealing edge 23, and the fixing portion 21 can collapse and deform during vibration and friction, thereby achieving a shock absorption effect and increasing the safety performance of the door glass 200. In addition, the free ends of the connecting part 24, the first sealing edge 22, the second sealing edge 23, and the fixing part 21 also define a drainage cavity. The drainage cavity is located outside the cavity. When the vehicle body pillar 10 is subjected to external force and vibrates, the formation of the two cavities can greatly increase the absorption of vibration energy, thereby enhancing the shock absorption and sealing effect of the sealing element 20.

[0038] According to some embodiments of the present invention, such as Figure 1 As shown, in the direction from one end of the connecting portion 24 to the other end, the connecting portion 24 extends along an arc that protrudes away from the first sealing edge 22. The connecting portion 24 is recessed from the door into the body, which can increase the space of the drainage chamber and thus increase the drainage effect.

[0039] According to some embodiments of the present invention, such as Figure 1As shown, the surface of the connecting part 24 facing the drainage cavity has a notch 241. The notch 241 extends through the connecting part 24 in the vertical direction. There may be one notch 241, or multiple notches 241 arranged at intervals. For example, there may be two, three or more notches 241. When the connecting part 24 is subjected to external force, such as when the window is raised or lowered or when the vehicle vibrates, the multiple notches 241 can cause the connecting part 24 to deform inward towards the vehicle body, making the window raising and lowering smoother and reducing the vibration caused by external force, thus achieving a shock absorption effect. At the same time, when the window is fully raised to the top, the connecting part 24 can make the second sealing edge 23 fit more closely to the door glass 200 under the action of the rebound force, thereby improving the sealing performance of the vehicle.

[0040] According to some embodiments of the present invention, such as Figure 1 As shown, a rearward-opening fixing groove 211 is formed on the fixing part 21, and the fixing part 21 is snapped into the vehicle body pillar 10 through the fixing groove 211. The fixing groove 211 is U-shaped and opens to the rear, which can ensure the fixed connection between the fixing part 21 and the vehicle body pillar 10; at the same time, the snap-fit ​​connection between the fixing part 21 and the vehicle body pillar 10 can increase the convenience of replacing the seal 20 and reduce vehicle maintenance costs.

[0041] According to some embodiments of the present invention, such as Figure 1 As shown, a plurality of first protrusions 2111 are formed on at least one sidewall of the fixing groove 211, and the plurality of first protrusions 2111 are in interference fit with the surface of the vehicle body pillar 10. For example, the first protrusions 2111 can be formed on one sidewall or on each sidewall of the fixing groove 211, and the number of first protrusions 2111 can be two, three or more. The interference fit between the plurality of first protrusions 2111 and the surface of the vehicle body pillar 10 can increase the safety of the fixed installation, making it difficult for the seal 20 to fall out of the vehicle body pillar 10, thereby ensuring the tightness of the installation and connection.

[0042] According to some embodiments of the present invention, such as Figure 1 As shown, a fixing groove 211 is formed at the front end of the fixing part 21, a second sealing edge 23 is connected to the front end of the fixing part 21, and a first sealing edge 22 is connected to the rear end of the fixing part 21. The fixing groove 211 formed at the front end of the fixing part 21 can increase the stability of the seal 20, and at the same time, it can provide more space for the first sealing edge 22 and the second sealing edge 23 to be arranged, increasing the convenience of installation.

[0043] According to some embodiments of the present invention, such as Figure 1As shown, the rear end of the fixing part 21 forms a rearwardly extending retaining section 212. The frameless door pillar assembly 100 also includes a pillar trim panel 30, which is located on the outside of the body pillar 10. The retaining section 212 is clamped between the pillar trim panel 30 and the body pillar 10. The retaining section 212 is connected to the first sealing edge 22. The retaining section 212 is clamped between the pillar trim panel 30 and the body pillar 10, which allows the rear end of the first sealing edge 22 to always abut against the edge of the pillar trim panel 30, thereby sealing the body pillar 10 with the first sealing edge 22, preventing dust, impurities, and rainwater from entering the vehicle body, and thus increasing the vehicle's safety performance.

[0044] According to some embodiments of the present invention, such as Figure 1 As shown, at least one side surface of the retaining section 212 is provided with a second protrusion 2121, and the retaining section 212 is interference-fitted between the vehicle pillar 10 and the pillar trim 30 through the second protrusion 2121. For example, the second protrusion 2121 can be formed on one side surface or both sides of the retaining section 212, and the number of second protrusions 2121 can be one, two or more. The interference fit between the second protrusion 2121 and the pillar trim 30 makes it difficult for the retaining section 212 to fall out of the vehicle pillar 10, thereby ensuring the sealing safety of the seal 20; at the same time, it can also provide a secondary seal for the vehicle pillar 10, further preventing impurities from entering the vehicle body, thereby increasing the service life of the vehicle. According to some embodiments of the present invention, such as Figure 1 As shown, the fixing part 21 includes a frame 213 and an elastic body 214, with the elastic body 214 covering the outside of the frame 213. The frame 213 provides support for the fixing part 21, thereby providing support for the seal 20; the elastic body, covering the outside of the frame 213, contacts the vehicle body pillar 10. When the vehicle body vibrates, the elastic body can reduce the vibration of the vehicle body that causes the fixing part 21 to vibrate, thereby reducing the vibration energy transmitted to the door glass 200 and increasing the vibration reduction and noise reduction effect of the window.
