Description

Technical Field

[0001] This invention belongs to the field of vehicle parts technology, specifically relating to a vehicle side panel bright strip and a vehicle. Background Technology

[0002] With the continuous development of the automotive industry, consumers are increasingly demanding higher standards for vehicle exterior design, sealing performance, and user comfort. Frameless doors, due to their clean and streamlined visual effect and premium feel, are widely used in mid-to-high-end models. However, frameless doors lack the structural support of traditional door and window frames. When the window glass is raised to its extreme position, it relies on the side structure of the vehicle body for positioning and sealing, which places higher demands on the design of the side bright strips.

[0003] In existing technologies, side panel trim strips are typically used for decoration and to help secure the upper edge of the window glass. However, several technical problems remain in practical applications: Firstly, due to the unavoidable dimensional tolerances between the body sheet metal parts and the trim strip itself during manufacturing and assembly, rigid connections or gapless fits between them can easily lead to assembly difficulties, stress concentration, or even trim strip deformation, affecting the overall vehicle assembly accuracy and appearance quality. Secondly, if there is a lack of effective buffering and sealing structures between the trim strip and the body sheet metal, vibrations or temperature changes during vehicle operation can easily cause abnormal noises, loosening, or sealing failure, thereby affecting the window's sealing performance and driving comfort.

[0004] Furthermore, the sealing structure in traditional side panel trim strips often uses solid rubber strips, which generate significant friction when in contact with the body sheet metal. This can easily lead to wear or excessive sliding resistance during assembly or use, affecting assembly efficiency and potentially causing a decline in sealing performance due to long-term friction. Meanwhile, for frameless doors, the sealing fit between the window glass and the side panel trim strip must balance elastic cushioning with a tight seal to ensure good waterproofing, dustproofing, and sound insulation.

[0005] Therefore, there is an urgent need to provide a vehicle side panel bright strip that has a reasonable structure, is easy to assemble, has reliable sealing, and can effectively absorb manufacturing errors, so as to solve the above-mentioned problems existing in the prior art. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a bright strip for the side of a vehicle and a vehicle, in view of the current state of the prior art.

[0007] The technical solution adopted by this invention to solve the above-mentioned technical problems is as follows: A bright strip for a vehicle side panel is proposed, fixedly installed on the side panel sheet metal of the vehicle body, used to retract and fix the upper edge of the window glass when the frameless door window glass is raised to its extreme position. The bright strip includes:

[0008] The bright strip body extends along the length of the vehicle and has a sealing groove for receiving the upper edge of the window glass.

[0009] A fastener for connecting the bright strip body and the vehicle side panel sheet metal, the fastener including a limiting part located between the bright strip body and the vehicle side panel sheet metal; the limiting part is configured to form a gap between the bright strip body and the vehicle side panel sheet metal to absorb processing errors of the bright strip body and the vehicle side panel sheet metal.

[0010] A sealing element is disposed on the bright strip body, the sealing element having a flocked surface that contacts and abuts against the body side sheet metal;

[0011] The flocked surface is used to reduce the relative motion friction between the seal and the body side sheet metal.

[0012] In the aforementioned vehicle side panel bright strip, the sealing element includes a connecting part and an abutting part. The connecting part is used to connect with the bright strip body, and the abutting part has a hollow structure. The flocked surface is disposed at one end of the abutting part facing the vehicle side panel sheet metal. The hollow structure of the abutting part is used to generate elastic deformation of the abutting part when the flocked surface abuts against the vehicle side panel sheet metal, so that the flocked surface abuts against the vehicle side panel sheet metal.

[0013] In the aforementioned vehicle side panel bright strip, the hollow structure of the abutment portion has a trapezoidal cross-section, and the flocked surface is disposed on the inclined surface of the trapezoid to extend the contact area between the flocked surface and the vehicle body side panel sheet metal.

[0014] In the aforementioned vehicle side panel bright strip, the bright strip body is provided with a first snap-fit ​​groove with an opening, the width of the opening being smaller than the width of the connecting part;

[0015] The connecting part can deform and pass through the opening when inserted into the first snap-fit ​​groove; and it can return to its shape after passing through the snap-fit, and be pressed and fixed against the inner wall of the first snap-fit ​​groove.

[0016] In the aforementioned vehicle side panel bright strip, the fastener includes two locking blocks spaced apart at one end of the limiting portion facing the side panel sheet metal of the vehicle body; the side panel sheet metal of the vehicle body is provided with a first locking hole; when the fastener is connected to the side panel sheet metal of the vehicle body, the two locking blocks are engaged in the first locking hole and abut against the inner wall of the first locking hole to fix it.

[0017] In the aforementioned vehicle side panel bright strip, the fastener includes two hooks spaced apart at one end of the limiting portion facing the bright strip body; each of the two hooks has a fastening portion at one end that is far apart from each other; the bright strip body has a second snap-fit ​​hole; when the fastener is connected to the bright strip body, the two hooks pass through the second snap-fit ​​hole, and the fastening portion abuts against the edge of the second snap-fit ​​hole to fix it.

[0018] In one of the aforementioned vehicle side panel bright strips, a sealing strip is snapped into the sealing groove; the sealing strip is used to movably abut against the end of the vehicle window glass.

[0019] In the aforementioned vehicle side panel bright strip, the inner wall of the sealing groove is provided with a snap-fit ​​part extending into the groove, and the outer wall of the sealing strip is provided with a second snap-fit ​​groove, the snap-fit ​​part engaging with the second snap-fit ​​groove.

[0020] In the aforementioned bright strip on the side of a vehicle, the width of the gap is 1mm to 2mm.

[0021] In addition to solving the above-mentioned technical problems, the present invention also proposes a vehicle including the aforementioned vehicle side panel bright strip.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) By integrating a bright strip body with a sealing groove, a fastener with a limiting part, and a sealing part with a flocked surface into the bright strip of the side wall, not only is the upper edge of the frameless door window glass effectively stored and fixed, but also the gap formed between the bright strip body and the side wall sheet metal of the vehicle body by the limiting part is used to effectively compensate for the processing and assembly tolerances, avoid stress concentration and assembly interference; at the same time, the contact contact between the flocked surface and the side wall sheet metal of the vehicle body significantly reduces the frictional resistance when sliding relative to each other, improves the assembly smoothness, reduces the risk of abnormal noise, and thus improves the NVH performance and assembly reliability of the whole vehicle.

[0024] (2) The seal is designed to include a connecting part and a hollow abutment part, with a flocked surface at the end of the abutment part facing the side panel of the vehicle body. This allows the abutment part to undergo elastic deformation under pressure, thereby achieving a tight fit between the flocked surface and the side panel of the vehicle body. This design not only ensures good sealing and cushioning performance but also avoids wear problems that may be caused by hard contact, significantly improving the adaptability and service life of the seal.

[0025] (3) The hollow structure of the abutment part is designed with a trapezoidal cross-section, and the flocked surface is placed on the inclined surface of the trapezoid, which effectively extends the contact area between the flocked surface and the body side sheet metal. This not only enhances the sealing stability, but also disperses the contact pressure, improves the durability and fatigue resistance of the seal during long-term use, and optimizes the friction characteristics to further reduce sliding resistance.

Detailed Implementation

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0033] like Figures 1 to 4 As shown, the present invention provides a bright strip for a vehicle side panel, which is fixedly installed on the side panel sheet metal 100 of the vehicle body. It is used to retract and fix the upper edge of the window glass when the window glass of the frameless door is raised to its limit position. The bright strip includes a bright strip body 200, a fastener 300, and a sealing element 400.

[0034] The bright strip body 200 extends along the length of the vehicle and is provided with a sealing groove 210 for receiving the upper edge of the window glass.

[0035] The fastener 300 is used to connect the bright strip body 200 and the vehicle side panel 100. It includes a limiting part 310, which is located between the bright strip body 200 and the vehicle side panel 100. The limiting part 310 is configured to form a gap between the two to absorb the processing errors caused by manufacturing or assembly of the bright strip body 200 and the vehicle side panel 100.

[0036] The sealing element 400 is disposed on the bright strip body 200, and has a flocked surface 410 that contacts and abuts against the body side sheet metal 100.

[0037] The flocked surface 410 is used to reduce the relative motion friction between the seal 400 and the body side sheet metal 100.

[0038] In this solution, by integrating a bright strip body 200 with a sealing groove 210, a fastener 300 with a limiting part 310, and a sealing part 400 with a flocked surface 410 into the bright strip of the side panel, not only is the upper edge of the frameless door window glass effectively stored and fixed, but the gap formed between the bright strip body 200 and the side panel sheet metal 100 of the vehicle body by the limiting part 310 is also used to effectively compensate for processing and assembly tolerances, avoid stress concentration and assembly interference. At the same time, the contact contact between the flocked surface 410 and the side panel sheet metal 100 of the vehicle body significantly reduces the frictional resistance during relative sliding, improves the smoothness of assembly, reduces the risk of abnormal noise, and thus improves the NVH performance and assembly reliability of the whole vehicle.

[0039] Furthermore, the sealing element 400 includes a connecting portion 420 and an abutting portion 430. The connecting portion 420 is used to connect with the bright strip body 200. The abutting portion 430 has a hollow structure, and the flocked surface 410 is disposed at one end of the abutting portion 430 facing the side panel 100 of the vehicle body. The hollow structure of the abutting portion 430 is used to generate elastic deformation of the abutting portion 430 when the flocked surface 410 abuts against the side panel 100 of the vehicle body, so that the flocked surface 410 abuts against the side panel 100 of the vehicle body.

[0040] The seal 400 is designed to include a connecting portion 420 and a hollow abutment portion 430. A flocked surface 410 is provided at the end of the abutment portion 430 facing the side panel 100 of the vehicle body, allowing the abutment portion 430 to undergo elastic deformation under pressure, thereby achieving a tight fit between the flocked surface 410 and the side panel 100 of the vehicle body. This design not only ensures good sealing and cushioning performance but also avoids wear problems that may be caused by hard contact, significantly improving the adaptability and service life of the seal 400.

[0041] The hollow structure of the contact part 430 has a trapezoidal cross-section, and the flocked surface 410 is set on the inclined surface of the trapezoid to extend the contact area between the flocked surface 410 and the body side sheet metal 100.

[0042] The hollow structure of the abutment portion 430 is designed with a trapezoidal cross-section, and the flocked surface 410 is placed on the inclined surface of the trapezoid, effectively extending the contact area between the flocked surface 410 and the body side sheet metal 100. This not only enhances the sealing stability but also disperses the contact pressure, improves the durability and fatigue resistance of the seal 400 in long-term use, and optimizes the friction characteristics, further reducing sliding resistance.

[0043] In order to achieve the connection between the bright strip body 200 and the seal 400, this solution provides a first snap-fit ​​groove 220 with an opening on the bright strip body 200. The width of the opening is smaller than the width of the connection part 420 of the seal 400.

[0044] When the connecting part 420 is inserted into the first snap-fit ​​groove 220, it undergoes elastic deformation due to the constraint of the opening, thus passing through the opening; after completely passing through the opening, the connecting part 420 returns to its original shape and abuts against the inner wall of the first snap-fit ​​groove 220, achieving a firm fixation.

[0045] By providing a first snap-fit ​​groove 220 on the bright strip body 200 with an opening width smaller than that of the connecting portion 420, the connecting portion 420 of the seal 400 undergoes elastic deformation during insertion, passing through the opening, and then springs back to its original position, tightly abutting against the inner wall of the snap-fit ​​groove. This achieves quick and reliable tool-free assembly. This structure simplifies the installation process, improves assembly efficiency, effectively prevents the seal 400 from falling off during use, and enhances the stability and reliability of the overall structure.

[0046] To achieve the connection between the fastener 300 and the side panel sheet metal 100 of the vehicle body, in this solution, the fastener 300 includes two snap-fit ​​blocks 320, which are spaced apart at one end of the limiting part 310 facing the side panel sheet metal 100 of the vehicle body; the side panel sheet metal 100 of the vehicle body is provided with a first snap-fit ​​hole; when the fastener 300 is connected to the side panel sheet metal 100 of the vehicle body, the two snap-fit ​​blocks 320 are snapped into the first snap-fit ​​hole and abut against the inner wall of the snap-fit ​​hole, thereby achieving fixation.

[0047] Two spaced-apart snap-fit ​​blocks 320 are provided at one end of the snap-fit ​​member 300 limiting part 310 facing the side panel sheet metal 100 of the vehicle body. These blocks engage with the first snap-fit ​​hole on the side panel sheet metal 100 to form a stable and reliable mechanical connection. This double snap-fit ​​block 320 structure effectively improves the connection strength and torsional resistance, preventing the side panel strip from loosening or shifting due to vibration during vehicle operation, thus ensuring long-term reliability and safety.

[0048] To achieve the connection between the fastener 300 and the bright strip body 200, in this solution, the fastener 300 includes two hooks 330, which are spaced apart at one end of the limiting part 310 facing the bright strip body 200; each of the outer ends of the two hooks 330 is provided with a fastening part 340; the bright strip body 200 is provided with a second engaging hole; when the fastener 300 is connected to the bright strip body 200, the two hooks 330 pass through the second engaging hole, and the fastening part 340 abuts against the edge of the second engaging hole, thereby achieving fixation.

[0049] A double hook 330 structure with a hook portion 340 is provided at the end of the limiting part 310 of the fastener 300 facing the bright strip body 200. This hook engages with the second snap-fit ​​hole on the bright strip body 200, allowing the hook portion 340 to abut against the edge of the hole for reliable fixation. This structure enables quick snap-fit ​​and self-locking between the fastener 300 and the bright strip body 200, eliminating the need for additional fasteners. This simplifies the assembly process, ensures a secure connection, and facilitates modular production and subsequent maintenance.

[0050] It is worth mentioning that a sealing strip 500 is engaged inside the sealing groove 210, and the sealing strip 500 is used to move and abut against the upper edge of the window glass.

[0051] A dedicated sealing strip 500 is installed within the sealing groove 210, ensuring it maintains dynamic contact with the glass end throughout the window's operation, thus providing a reliable dynamic seal and effectively preventing the intrusion of rainwater, dust, and noise. This design ensures excellent sealing performance while also balancing smooth glass movement, significantly enhancing the overall sealing effect and user experience of the frameless door.

[0052] Furthermore, the inner wall of the sealing groove 210 is provided with a snap-fit ​​portion 230 extending into the groove, and the outer wall of the sealing strip 500 is provided with a second snap-fit ​​groove 510. The snap-fit ​​portion 230 and the second snap-fit ​​groove 510 cooperate with each other to achieve snap-fit ​​fixation.

[0053] By providing a snap-fit ​​portion 230 extending into the groove on the inner wall of the sealing groove 210, and a corresponding second snap-fit ​​groove 510 on the outer wall of the sealing strip 500, a reliable snap-fit ​​fit is formed, ensuring that the sealing strip 500 is firmly installed and not easily detached. This structure effectively improves the positioning accuracy and pull-out resistance of the sealing strip 500, ensuring stable sealing performance even under long-term use or extreme working conditions.

[0054] Preferably, the gap width between the bright strip body 200 and the vehicle side panel 100 is 1mm to 2mm.

[0055] Limiting the gap to between 1mm and 2mm is sufficient to effectively absorb conventional manufacturing and assembly tolerances, avoiding assembly interference or localized stress concentration, while also preventing excessive gaps from affecting the smoothness of the appearance or the rigidity of the structure. This dimensional range has been engineering-proven, balancing functionality and aesthetics, and is a key parameter for achieving high assembly yield and a high-quality feel.

[0056] The present invention also provides a vehicle that includes the bright stripe on the vehicle side panel as described above.

[0057] In summary, this solution provides a vehicle side panel bright strip with a reasonable structure, convenient assembly, and reliable sealing, as well as a vehicle containing the bright strip. By setting a snap-fit ​​component 300 with a limiting part 310 between the bright strip body 200 and the vehicle side panel sheet metal 100, a controllable gap of 1mm to 2mm is formed, effectively compensating for manufacturing and assembly tolerances and avoiding stress concentration and assembly interference. At the same time, an elastic sealing component 400 with a flocked surface 410 is integrated on the bright strip body 200, significantly reducing the frictional resistance between it and the vehicle side panel sheet metal 100, improving assembly smoothness and suppressing abnormal noise. The sealing component 400 adopts a hollow trapezoidal abutment part 430 design, which not only extends the contact area with the vehicle body sheet metal and enhances sealing stability, but also generates elastic deformation under pressure to achieve a tight fit. In addition, the bright strip body 200, the sealing strip 500, and the snap-fit ​​component 300 all adopt a snap-fit ​​quick-installation structure, eliminating the need for additional fasteners, simplifying the production process, and improving assembly efficiency and connection reliability. The overall solution fully considers the multiple requirements of frameless doors for aesthetics, sealing, durability and NVH performance, and is particularly suitable for mid-to-high-end models, with significant technological progress and good prospects for industrial application.
