[0024] Furthermore, this utility model also proposes an automobile, which includes a vehicle body, a body sheet metal, a first sealing strip, a second sealing strip, and a pillar trim panel as described in any of the above technical solutions. The body sheet metal, the first sealing strip, and the second sealing strip are all connected to the vehicle body, and the first sealing strip and the second sealing strip are arranged at intervals along the first direction. The two ends of the body sheet metal arranged opposite each other along the first direction are the first end and the second end, respectively. The first sealing strip is provided with a first groove for accommodating at least a portion of the structure of the first claw and the first end. The first claw abuts against the first end, and the first claw is away from... One side of the first end and the side of the first end away from the first claw respectively abut against the two side walls of the first groove arranged opposite to each other along the second direction, so as to restrict the movement of the first claw and the first end relative to the first sealing strip; the second sealing strip is provided with a second groove for accommodating at least a portion of the structure of the second claw and the second end, the second claw and the second end abut against each other, the side of the second claw away from the second end and the side of the second end away from the second claw respectively abut against the two side walls of the second groove arranged opposite to each other along the second direction, so as to restrict the movement of the second claw and the second end relative to the second sealing strip.

[0025] In this embodiment of the utility model, by setting a first claw and a second claw on both sides of the trim panel body, they extend into the corresponding groove of the corresponding sealing strip together with the corresponding ends of the body sheet metal. The claws abut against the ends of the corresponding body sheet metal and the groove walls on opposite sides along the second direction, forming a bidirectional clamping limiting structure, thus achieving stable positioning of the B-pillar trim panel in the first direction. Simultaneously, the first and second clips are spaced apart in the third direction, completing the main fixed connection between the B-pillar trim panel and the body sheet metal. This design fully utilizes the groove structure of the sealing strip, allowing the first and second claws to work together with the body sheet metal and the sealing strip after assembly to bear the lateral load of the B-pillar trim panel along its length, effectively improving connection rigidity, suppressing loosening and abnormal noise, and significantly reducing the dependence on the number of clips. Compared to the traditional pillar trim panel technology that generally uses up to nine clips to ensure connection stability, this embodiment, through the above-mentioned collaborative limiting mechanism, can significantly reduce the number of clips used while meeting strength and reliability requirements, reducing the procurement cost and inventory management complexity of non-metallic connectors. The first clip consists of a first snap-fit ​​component, a second snap-fit ​​component, and fasteners. The first snap-fit ​​component engages with the body sheet metal, and the second snap-fit ​​component engages with the trim panel body. The fasteners detachably connect the two, achieving primary fixation between the trim panel body and the body sheet metal. The second clip engages with both the trim panel body and the body sheet metal, and is spaced apart from the first clip along a third direction, providing auxiliary support. This connection structure simplifies assembly while meeting connection strength requirements and facilitates disassembly and maintenance. The first direction, the third direction, and the second direction are perpendicular to each other, conforming to the actual assembly space layout of the vehicle body, resulting in a reasonable structural arrangement. This embodiment of the invention, by employing a connection structure combining clips and claws, utilizes the synergistic limiting effect of the claws, the body sheet metal, and the sealing strips to effectively reduce the number of clips and lower component costs. Simultaneously, it achieves reliable connection, rapid installation, and convenient disassembly of the B-pillar trim panel, solving the problems of difficult assembly, poor maintainability, and high cost associated with traditional pure clip-fit ​​connection methods. It boasts advantages such as simple structure, low cost, and good maintainability. Attached Figure Description

[0039] In the field of automotive interior assembly technology, pillar trim panels (such as B-pillar trim panels) are key decorative components covering the interior structure of the vehicle body. They not only enhance the visual appeal of the interior but also serve the important function of concealing sheet metal parts, wiring harnesses, and sealing structures. As consumers increasingly demand higher quality and more efficient assembly, the installation method of pillar trim panels needs to balance connection reliability, assembly convenience, and ease of maintenance. However, the traditional snap-fit ​​connection structure commonly used in automotive technology has revealed problems such as difficult installation and poor maintainability in practical applications, making it difficult to meet the demands of modern automotive manufacturing for efficient assembly.

[0040] After careful research, the applicant discovered that current B-pillar trim panels are typically quite large along the vehicle's height. To ensure a stable connection between the trim panel and the body throughout its length, preventing loosening, rattling, or detachment, traditional designs rely on evenly spaced plastic clips on the back of the trim panel, which are then individually pressed into mounting holes on the body sheet metal. While this connection method is simple in structure and technically mature, it necessitates increasing the number of clips to guarantee overall connection strength and stability, often requiring up to nine clips. Such a large number of connection points significantly increases parts procurement and inventory management costs, and also makes the assembly process cumbersome and time-consuming. Operators must align and press each clip individually, and even slight deviations can cause clip breakage or trim panel deformation. During later maintenance and disassembly, each clip must be pried open to remove the trim panel, easily damaging the clips and even the B-pillar trim panel itself, greatly reducing maintenance efficiency and user experience. Furthermore, as clips are consumable parts, an increased number of clips also means a higher failure rate over long-term use, further impacting the overall vehicle quality reputation.

[0041] The main purpose of this utility model is to propose an automotive pillar trim panel and an automotive vehicle to solve the problem of how to improve the ease of disassembly, assembly, and maintenance of automotive pillar trim panels.

[0042] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the automotive pillar trim panel 100 includes a B-pillar trim panel 1, a first buckle 2, and a second buckle 3. The B-pillar trim panel 1 includes a trim panel body 11, a first claw 12, and a second claw 13. The first claw 12 and the second claw 13 are disposed on opposite sides of the trim panel body 11 along a first direction. The first claw 12 and the first end 2001 of the body sheet metal 200 are used to extend into the first groove 2101 of the first sealing strip 210, and the opposite sides of the first claw 12 along a second direction respectively abut against the groove walls of the first end 2001 and the first groove 2101 to restrict the movement of the first claw 12 relative to the first end 2001 and the first sealing strip 210. The second claw 13 and the second end 2002 of the body sheet metal 200 are used to extend into the second sealing strip 220. The second claw 13 is located in the second slot 2201, and the two sides of the second claw 13 arranged opposite to each other along the second direction abut against the groove wall of the second end 2002 and the second slot 2201 respectively, so as to restrict the movement of the second claw 13 relative to the second end 2002 and the second sealing strip 220; the first buckle 2 includes a first snap-fit ​​21, a second snap-fit ​​22 and a fastener 23. The first snap-fit ​​21 snaps into the body sheet metal 200, and the second snap-fit ​​22 snaps into the trim panel body 11. The first snap-fit ​​21 and the second snap-fit ​​22 are both detachably connected to the fastener 23. The second snap-fit ​​22 is located at the top of the trim panel body 11; the trim panel body 11 and the body sheet metal 200 are both snapped into the second buckle 3. The first buckle 2 and the second buckle 3 are spaced apart along the third direction, and the first direction, the third direction and the second direction are perpendicular to each other.

[0043] In the embodiments of this utility model, such as Figure 1 and Figure 2As shown, the first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction (also the vehicle height direction). By setting the first claw 12 and the second claw 13 on both sides of the trim panel body 11, they extend into the corresponding groove of the corresponding sealing strip together with the corresponding ends of the body sheet metal 200. The claws abut against the ends of the corresponding body sheet metal 200 and the groove wall of the groove on opposite sides along the second direction, forming a bidirectional clamping limiting structure, thereby achieving stable positioning of the B-pillar trim panel 1 in the first direction. At the same time, the first buckle 2 and the second buckle 3 are arranged at intervals in the third direction to complete the main fixed connection between the B-pillar trim panel 1 and the body sheet metal 200. This design fully utilizes the slot structure of the sealing strip, allowing the first claw 12 and the second claw 13 to work together with the body sheet metal 200 and the sealing strip after assembly to bear the lateral load along the length of the B-pillar trim panel 1. This effectively improves the connection rigidity, suppresses loosening and abnormal noise, and significantly reduces the dependence on the number of clips. Compared to the traditional pillar trim panel, which generally uses up to nine clips to ensure connection stability, this embodiment, through the above-mentioned collaborative limiting mechanism, can significantly reduce the number of clips used while meeting strength and reliability requirements, reducing the procurement cost and inventory management complexity of non-metallic connectors. Simultaneously, the first clip 2 is formed by the first clip... The structure consists of a first snap-fit ​​connector 21, a second snap-fit ​​connector 22, and a fastener 23. The first snap-fit ​​connector 21 snaps into the body sheet metal 200, and the second snap-fit ​​connector 22 snaps into the trim panel body 11. The fastener 23 detachably connects the two, thus achieving the main fixation between the trim panel body 11 and the body sheet metal 200. The second snap-fit ​​3 engages with the trim panel body 11 and the body sheet metal 200, and is spaced apart from the first snap-fit ​​2 along a third direction to provide auxiliary support. This connection structure simplifies the assembly method while meeting the connection strength requirements, and facilitates disassembly and maintenance. The first direction, the third direction, and the second direction are perpendicular to each other, which conforms to the actual assembly space layout of the vehicle body, and the structural arrangement is reasonable.

[0044] The technical solution of this utility model adopts a connection structure that combines buckles and claws. By utilizing the synergistic limiting effect of the claws, the body sheet metal 200, and the sealing strip, the number of buckles is effectively reduced and the cost of components is lowered. At the same time, it achieves reliable connection, quick installation, and convenient disassembly of the B-pillar trim panel 1, solving the problems of difficult assembly, poor maintainability, and high cost of traditional pure buckle connection methods. It has the advantages of simple structure, low cost, and good maintainability.

[0045] Please see Figure 2In one embodiment, the first claw 12 includes a first connecting plate 121, a second connecting plate 122, and a third connecting plate 123. Both the first connecting plate 121 and the third connecting plate 123 are connected to the second connecting plate 122, and are spaced apart along a second direction. The first connecting plate 121 and the third connecting plate 123 extend away from the second claw 13. The third connecting plate 123 is connected to the decorative panel body 11, and the first connecting plate 121, the second connecting plate 122, and the third connecting plate 123 enclose the [missing information - likely a specific area or structure]. A receiving groove 124 is formed, and an opening 1241 for the first sealing strip 210 to pass through is formed on the side of the receiving groove 124 away from the second claw 13. The two sides of the first connecting plate 121, which are arranged opposite to each other along the second direction, abut against the groove walls of the first end 2001 and the first slot 2101, respectively. Specifically, the first claw 12 forms a U-shaped receiving groove 124 with a lateral opening 1241 through the first connecting plate 121, the second connecting plate 122 and the third connecting plate 123, so that the first sealing strip 210 can be inserted from the opening 1241 side and stably limited. The third connecting plate 123 connects to the trim panel body 11 to achieve structural fixation. The second connecting plate 122 serves as a transition section to enhance overall rigidity, while the first connecting plate 121 acts as the main limiting part. After assembly, its two sides abut against the first end 2001 of the body sheet metal 200 and the groove wall of the first slot 2101, respectively, forming a bidirectional clamping effect in the second direction. This effectively restricts the relative movement between the trim panel body 11 and the body sheet metal 200, improving connection rigidity and vibration resistance. This design fully utilizes the multi-plate combination structure to achieve the strength and functional integration of the claws. Without adding extra parts, it achieves reliable limiting through cooperation with the sealing strip and the body sheet metal 200. This helps reduce the number of main connecting clips, lower component costs and assembly complexity, while improving connection stability and durability. It has the advantages of reasonable structure, reliable function, and low cost.

[0046] Please see Figure 2In one embodiment, the side of the third connecting plate 123 facing the first connecting plate 121 can abut against the outer wall of the first sealing strip 210. Specifically, this structural design allows the first claw 12, when engaging with the first sealing strip 210, not only to limit the first connecting plate 121 against the first end 2001 of the body sheet metal 200 and the groove wall of the first slot 2101, but also for the third connecting plate 123 to contact the outer wall of the first sealing strip 210 from the other side, further restricting the displacement of the first sealing strip 210 along the second direction in the assembled state and enhancing the stability of the connection. Through the abutment action between the third connecting plate 123 and the outer wall of the first sealing strip 210, the first sealing strip 210 can be effectively prevented from loosening or detaching due to vibration or assembly stress, improving sealing reliability and the overall structure's vibration resistance. Meanwhile, the abutment relationship and the bidirectional limiting effect of the first connecting plate 121 enhance the lateral constraint capability of the first claw 12 on the trim panel body 11, which helps to further reduce the dependence on the number of main connecting buckles (first buckle 2 and second buckle 3), improve assembly efficiency and structural integration, and achieve a comprehensive improvement in connection reliability, sealing stability and cost control through structural optimization without adding extra parts.

[0047] Please see Figure 2 In one embodiment, the extension length of the third connecting plate 123 is greater than the extension length of the first connecting plate 121. Specifically, this structural design allows the first sealing strip 210 to first contact the longer third connecting plate 123 during assembly, forming a preliminary abutment limit in the second direction to achieve pre-positioning. Through this pre-positioning action, the relative position of the B-pillar trim 1 and the first sealing strip 210 in the second direction is fixed in advance to avoid misalignment or skewness. Subsequently, the assembly force is continued to be applied, pushing the B-pillar trim 1 as a whole to move to the left in the first direction, so that the first claw 12 and the first end 2001 of the body sheet metal 200 simultaneously extend into the first slot 2101 of the first sealing strip 210, completing the snap-fit ​​engagement. Since the front end of the third connecting plate 123 protrudes from the first connecting plate 121, it participates in positioning first, achieving a step-by-step assembly effect of first guiding and limiting and then snapping in. This significantly reduces the assembly difficulty when aligning the first claw 12 with the first slot 2101, prevents damage to the first claw 12 caused by initial misalignment, and realizes automatic alignment and sequential positioning during the assembly process. It has the advantages of easy alignment, smooth assembly, and high reliability.

[0048] Please see Figure 2In one embodiment, a guide slope 1211 is provided on the side of the first connecting plate 121 facing the third connecting plate 123. The guide slope 1211 is used to guide the first sealing strip 210 into the receiving groove 124. Specifically, by providing an inclined transition surface on the inner side of the first connecting plate 121, the first sealing strip 210 is guided during the assembly process. When the trim panel body 11 approaches the first sealing strip 210, the guide slope 1211 contacts the end or outer edge of the first sealing strip 210, generating a gentle pushing force, which causes the first sealing strip 210 to slide smoothly into the receiving groove 124 formed by the first connecting plate 121, the second connecting plate 122 and the third connecting plate 123. This effectively reduces the assembly resistance and avoids deformation or damage to the sealing strip or impact damage to the claw structure due to hard interference. The design of the guide ramp 1211 improves the smoothness and fault tolerance of the assembly process, especially in the case of slight misalignment, it can still achieve smooth assembly, improve production cycle and assembly reliability, realize the smooth introduction of sealing strip, improve assembly processability, and further enhance the practicality and production adaptability of the connection structure.

[0049] Please see Figure 2 In one embodiment, the decorative panel body 11 is used to abut against the overlapping portion 2102 of the first sealing strip 210 to restrict the overlapping portion 2102 from moving towards the first connecting plate 121. The decorative panel body 11 and the first sealing strip 210 form a sealing cavity 4, and the receiving groove 124 and the first slot 2101 are both located in the sealing cavity 4. Specifically, this structure forms a surface contact between the decorative panel body 11 and the overlapping portion 2102 of the first sealing strip 210, effectively preventing the first sealing strip 210 from shifting inward (i.e., towards the first connecting plate 121) during assembly or use, thereby improving the stability and reliability of the installation of the first sealing strip 210. Meanwhile, the trim panel body 11 and the first sealing strip 210 together form a closed sealing cavity 4, enclosing the receiving groove 124 of the first claw 12 and the first slot 2101 inside. This not only improves the aesthetics of the overall structure and prevents the internal structure from being exposed, but also enhances the protection of the engagement area, preventing external impurities such as dust and moisture from intruding between the slot and the claw, affecting the limiting function or causing abnormal noise. In addition, the presence of the sealing cavity 4 further strengthens the multi-layer sealing effect of the B-pillar trim panel 1, which helps to improve the waterproof and dustproof performance of the whole vehicle. It achieves reliable limiting of the first sealing strip 210, environmental protection of the connection structure, and integrated optimization of sealing performance, and has the advantages of compact structure, reliable sealing, and good protection.

[0050] Please see Figure 2In this embodiment, the second claw 13 and the first claw 12 have the same structure. This design achieves structural uniformity of the claws on both sides, which is conducive to the standardization of mold development and manufacturing, and reduces the cost of parts design, processing and inventory management. By using the same claw structure to be set at both ends of the trim panel body 11 along the first direction, it can form the same clamping and limiting cooperation with the sealing strips on both sides of the vehicle body and the body sheet metal 200, ensuring that the B-pillar trim panel 1 has the same connection rigidity, positioning accuracy and vibration resistance on both sides, and improving assembly consistency and structural balance. At the same time, the universal design facilitates automated assembly and quality control, and reduces the risk of misassembly in the production process. This structure also simplifies the design verification process. Only mechanical performance testing of a single claw structure is needed to cover the application on both sides, improving development efficiency and achieving a synergistic improvement in design simplification, cost optimization and manufacturing convenience.

[0051] Please see Figure 3In one embodiment, the first snap-fit ​​member 21 is provided with a stop 211, and the body sheet metal 200 is provided with a first mounting hole 2003. The first snap-fit ​​member 21 passes through the first mounting hole 2003, and the stop 211 can abut against the side of the body sheet metal 200 away from the trim panel body 11 to restrict the movement of the body sheet metal 200 away from the trim panel body 11; the second snap-fit ​​member 22 is provided with a boss 221, and the trim panel body 11 is provided with a second mounting hole 111. The second snap-fit ​​member 22 passes through the second mounting hole 111, and the boss 221 can abut against the side of the trim panel body 11 away from the body sheet metal 200 to restrict the movement of the trim panel body 11 away from the body sheet metal 200; the fastener 23 is packaged with... The structure includes a screw 231, a first threaded hole 212 on the first snap-fit ​​member 21, and a second threaded hole 222 on the second snap-fit ​​member 22. Both the first threaded hole 212 and the second threaded hole 222 are threadedly engaged with the screw 231. Alternatively, the B-pillar trim panel 1 is a one-piece molded component. Specifically, this structure allows the first snap-fit ​​member 21 and the second snap-fit ​​member 22 to penetrate the body sheet metal 200 and the trim panel body 11 respectively. The stop 211 abuts against the body sheet metal 200, and the boss 221 abuts against the trim panel body 11, forming a bidirectional axial limit. This effectively prevents the snap-fit ​​members from shifting or falling off during the connection process, ensuring assembly stability and preventing separation due to the roof 300 on the top of the vehicle body. Screws 231 are screwed into the first threaded hole 212 and the second threaded hole 222 in sequence, connecting the first snap-fit ​​part 21, the body sheet metal 200, and the second snap-fit ​​part 22 into one unit, realizing a detachable and secure connection between the trim panel body 11 and the body sheet metal 200. This connection method has strong load-bearing capacity and reliable connection. Disassembly only requires unscrewing screws 231 to separate the trim panel, eliminating the need for destructive operations and significantly improving maintenance convenience. Simultaneously, the split snap-fit ​​design facilitates assembly in confined spaces and adapts to complex vehicle body structure layouts. The structure, secured by double snap-fit ​​parts and screws 231, achieves a high-strength, detachable, and easily maintainable connection between the B-pillar trim panel 1 and the vehicle body, offering advantages such as stable connection, convenient assembly and disassembly, and high reliability. Furthermore, the B-pillar trim panel 1 is a one-piece molded component with strong overall structural integrity and high rigidity, avoiding assembly errors and the risk of loose connections caused by splicing multiple parts. It also simplifies molds and production processes, reduces manufacturing costs, and improves product consistency.

[0052] According to one embodiment of the present invention, the fastener 23 can be detachably connected to the first snap-fit ​​member 21 and the second snap-fit ​​member 22 by means of bolts and nuts.

[0053] Please see Figure 4In one embodiment, the second buckle 3 is provided with a first limiting platform 31 and a second limiting platform 32, the body sheet metal 200 is provided with a third mounting hole 2004, and the trim panel body 11 is provided with a fourth mounting hole 112. One end of the second buckle 3 passes through the third mounting hole 2004 so that the first limiting platform 31 can abut against the body sheet metal 200 to restrict the movement of the body sheet metal 200 relative to the second buckle 3. The other end of the second buckle 3 passes through the fourth mounting hole 112 so that the second limiting platform 32 can abut against the trim panel body 11 to restrict the movement of the trim panel body 11 relative to the second buckle 3. Specifically, this structure uses the second buckle 3 to pass through the body sheet metal 200 and the trim panel body 11, and uses the first limiting platform 31 and the second limiting platform 32 to form axial bidirectional abutment with the body sheet metal 200 and the trim panel body 11 respectively, to achieve stable positioning of the second buckle 3 itself and prevent it from falling off or moving axially during use. Meanwhile, this connection method reliably connects the trim panel body 11 to the body sheet metal 200 via the second clip 3, providing auxiliary fixing support and enhancing the overall connection rigidity of the B-pillar trim panel 1. It effectively suppresses loosening or abnormal noise caused by vibration, especially in non-top areas (such as the middle or lower parts). This clip-on structure is easy to assemble, requiring no additional fastening devices to complete installation, reducing the number of parts and assembly costs. Disassembly only requires applying a reverse force to disengage the clips, making operation convenient and less likely to damage the trim panel body 11 or the second clip 3. This facilitates later maintenance and replacement, offering advantages such as reliable connection, efficient assembly, good maintainability, and low cost.

[0054] Please see Figure 1 and Figure 4In one embodiment, a sealing element 5 is provided between the first limiting platform 31 and the body sheet metal 200, with the two opposite sides of the sealing element 5 abutting against the first limiting platform 31 and the body sheet metal 200 respectively; and / or, the number of second buckles 3 is multiple, and the multiple second buckles 3 are spaced apart along a third direction; and / or, the number of first claws 12 is multiple, and the multiple first claws 12 are spaced apart along a third direction; and / or, the number of second claws 13 is multiple, and the multiple second claws 13 are spaced apart along a third direction; specifically, in this structure, the number of each component can be flexibly set according to the length of the B-pillar trim panel 1, the structural layout, and the connection strength requirements, so as to achieve the optimal match between performance and cost. In this embodiment, the number of second buckles 3 is 4, and the number of first claws 12 and second claws 13 is 5 each, and they are all spaced apart along a third direction, which not only ensures the connection rigidity and stress uniformity of the B-pillar trim panel 1 throughout its entire length, but also avoids over-design, taking into account both reliability and economy. The distribution of multiple second clips 3 provides auxiliary fixing support, enhancing the overall connection stability. Multiple first claws 12 and second claws 13 form continuous clamping and limiting relationships with the body sheet metal 200 and sealing strips, effectively suppressing vibration, loosening, and abnormal noise of the trim panel during vehicle operation. Simultaneously, a seal 5 is provided between the first limiting platform 31 and the body sheet metal 200 to fill the assembly gap, preventing water and dust from intruding from the clip installation area and improving the sealing performance of the B-pillar area. The seal 5 maintains elastic contact under pressure, further improving connection durability, achieving a comprehensive technical effect of structural stability, reliable sealing, good vibration resistance, efficient assembly, and convenient maintenance.
