Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, 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. Therefore, they should not be construed as limitations on this application.

[0042] In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise specified precisely.

[0043] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0044] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0045] As mentioned in the background section, with the rapid development of the automotive industry, most consumers have increasingly stronger demands for cars, paying close attention to issues such as safety and aesthetics. The widespread adoption of automobiles has spurred development in the manufacturing and design of automotive components.

[0046] In related technologies, vehicle body pillars include A-pillars, B-pillars, C-pillars, and D-pillars. The A-pillar, also known as the front pillar, is located on either side of the windshield, connecting the roof to the engine compartment. The B-pillar, also known as the center pillar, is located between the front and rear doors, connecting the roof to the chassis, and plays a crucial protective role in side collisions. The C-pillar, also known as the rear pillar, is located between the rear door and the rear windshield; some models (such as SUVs / MPVs) also have a D-pillar behind the C-pillar. The B-pillar not only protects the safety of passengers, but also typically has an interior trim panel installed on its inner side, which enhances aesthetics and improves the user experience.

[0047] Currently, the interior trim panels for automotive B-pillars are all manufactured using a modular approach, typically featuring an inverted structure and densely reinforced supporting structures. The B-pillar trim panels also incorporate mounting structures to attach them to the vehicle body sheet metal. This results in complex mold manufacturing, with molds significantly heavier than those for parts of the same size. This is because the interior trim panels require high precision in appearance and high structural strength to ensure stable connection with the sheet metal, leading to complex and costly molds for their production.

[0048] Based on the aforementioned technical problems, this application provides a vehicle body pillar interior panel structure and a vehicle. In this technical solution, the vehicle body pillar interior panel structure includes: an interior panel and a liner; the liner is connected to the inner side of the interior panel and adheres to the inner surface of the interior panel, supporting the interior panel; the liner is provided with a fastener that can connect to the vehicle body sheet metal, and the interior panel can be connected to the vehicle body sheet metal through the liner. By setting the liner, the liner provides support for the interior panel, and the fastener is integrated into the liner rather than the interior panel, reducing the structural complexity of the interior panel. The interior panel can focus on aesthetics and tactile experience, while the liner focuses on mechanical performance and installation function. By setting the liner inside the interior panel, a double-layer structure of "decorative layer + structural layer" is formed, enabling rapid assembly through bonding or snap-fitting, balancing functionality and design flexibility. This simplifies mold development and production processes, reducing manufacturing costs. This application uses the B-pillar as an example for illustration. Of course, the vehicle body pillar interior panel structure provided in this application embodiment can also be applied to the A-pillar, B-pillar, C-pillar, and D-pillar, without limitation.

[0049] It should be noted that, Figures 1 to 5 The diagram illustrates a simplified representation of the body pillar interior panel structure and other components within the vehicle. The specific structures of the body pillar interior panel structure and other components within the vehicle are not limited to... Figures 1 to 5 of examples.

[0050] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0051] Reference Figures 1 to 5 As shown in the embodiment of this application, a vehicle body pillar interior panel structure and a vehicle are provided. The vehicle body pillar interior panel structure includes an interior panel 100 and a liner 200. The liner 200 is connected to the inner side of the interior panel 100 and is attached to the inner surface of the interior panel 100. The liner 200 supports the interior panel 100.

[0052] Here, the interior panel 100 typically has an inner side and an outer side. The outer side of the interior panel 100 usually faces the interior of the vehicle, which is the exterior surface that the driver and passengers can directly observe. The inner side of the interior panel 100 is provided with a liner 200.

[0053] The liner 200 is provided with a fastener 300, which can be connected to the body sheet metal. The interior panel 100 can be connected to the body sheet metal through the liner 200.

[0054] The interior panel 100 only needs to meet the appearance precision requirements and does not need to integrate a high-strength connection structure. By setting a liner 200, the liner 200 provides support for the interior panel 100. The fastener 300 is integrated into the liner 200 instead of the interior panel 100, reducing the structural complexity of the interior panel 100. The liner 200 can be connected to the body sheet metal through the fastener 300.

[0055] The liner 200 can be used as an independent load-bearing component to ensure a reliable connection with the body sheet metal.

[0056] Through the above-described configuration, the interior panel 100 can focus on aesthetics and tactile experience, while the liner 200 focuses on mechanical performance and installation functionality. By placing the liner 200 inside the interior panel 100, rapid assembly can be achieved through bonding or snap-fitting, balancing functionality and design flexibility. This forms a two-layer structure of "decorative layer + structural layer," simplifying the vehicle assembly process. This also allows for the use of thinner, more easily moldable materials for the interior panel 100, simplifying mold development and production processes, and reducing manufacturing costs.

[0057] In one possible implementation, the interior trim panel 100 includes an upper trim panel 110 and a lower trim panel 120. The upper trim panel 110 is connected to the upper part of the lower trim panel 120 along the length direction of the lower trim panel 120, and the upper trim panel 110 and the lower trim panel 120 are integrally formed.

[0058] In the above embodiment, the upper trim panel 110 and the lower trim panel 120 are integrally formed along the length direction, avoiding the stress concentration problem at the joints in traditional split designs, reducing structural weaknesses caused by splicing, and thus enhancing the overall resistance to deformation. The integral forming makes the material continuity of the upper trim panel 110 and the lower trim panel 120 better, which can optimize mechanical properties, such as bending and impact resistance, and improve the safety protection capability of the occupant cabin.

[0059] Furthermore, in traditional solutions, the upper trim panel 110 and the lower trim panel 120 need to be manufactured and assembled separately, while one-piece molding only requires a single mold and a one-time molding process, simplifying the production process, reducing assembly time and labor costs, reducing the number of molds needed, and lowering both initial development costs and subsequent mass production costs. It also avoids problems such as color difference and uneven gaps found in traditional splicing processes, further enhancing visual appeal.

[0060] In one possible implementation, the first end of the liner 200 is attached to the inner surface of the upper trim panel 110, the second end of the liner 200 is attached to the inner surface of the lower trim panel 120, and the length of the liner 200 is less than the sum of the lengths of the upper trim panel 110 and the lower trim panel 120.

[0061] In the above embodiment, the length of the liner 200 is less than the sum of the lengths of the upper trim panel 110 and the lower trim panel 120, which reduces the amount of material used in the liner 200, thereby lowering raw material costs and processing energy consumption. By reducing the coverage area of ​​the liner 200, the overall weight is reduced while ensuring structural strength, which is in line with the trend of automotive lightweighting.

[0062] The liner 200 only fits a portion of the upper trim panel 110 and lower trim panel 120, avoiding the complex assembly process of full-length coverage. This allows the liner 200 to be quickly assembled with the interior trim panel 100 through partial positioning, simplifying the assembly process and reducing labor costs. The areas of the upper trim panel 110 and lower trim panel 120 not covered by the liner 200 can be directly connected to the body sheet metal through other connecting structures, forming multi-point distributed load-bearing, balancing overall stress, and improving impact resistance.

[0063] Reference Figure 1 and Figure 2 As shown, in one possible implementation, the portion of the upper trim panel 110 not connected to the liner 200 is provided with a first connecting portion 400, and the portion of the lower trim panel 120 not connected to the liner 200 is provided with a second connecting portion 500.

[0064] The upper trim panel 110 is connected to the body sheet metal via the first connecting part 400, and the lower trim panel 120 is connected to the body sheet metal via the second connecting part 500.

[0065] In a specific implementation, at least one of the first connecting portion 400 and the second connecting portion 500 can be a connecting boss, on which bolts are provided. The portion of the upper trim panel 110 not connected to the liner 200 is bolted to the body sheet metal, and the portion of the lower trim panel 120 not connected to the liner 200 can also be bolted to the body sheet metal. Here, those skilled in the art will realize that bolt holes are usually provided on the body sheet metal, and this application does not limit the specific structure of the body sheet metal.

[0066] In the above embodiment, the upper trim panel 110 is directly connected to the body sheet metal via the first connecting part 400, and the lower trim panel 120 is directly connected to the body sheet metal via the second connecting part 500, forming a dual fixing system of "support by the liner 200 + direct connection". This distributes the stress points to multiple areas, avoiding deformation or detachment due to concentrated stress at a single point, and significantly improving the overall rigidity of the B-pillar in side collisions. The areas of the upper and lower trim panels 120 not covered by the liner 200 are connected to the body sheet metal via the first connecting part 400 and the second connecting part 500, ensuring that the mechanical properties of the body pillar interior panel 100 are evenly distributed along its length.

[0067] In one possible implementation, the interior trim panel 100 is provided with multiple rows of snap-fit ​​members, which are arranged along the length of the interior trim panel 100, and at least one snap-fit ​​member is provided in the same row. The interior trim panel 100 can be detachably connected to the liner 200 through the multiple rows of snap-fit ​​members.

[0068] In the above embodiment, multiple rows of snap-fit ​​connectors are arranged along the length of the interior panel 100, forming continuous and uniform stress points, tightly connecting the interior panel 100 and the lining plate 200 into a whole. This disperses the impact force of the body sheet metal on the interior panel 100, avoiding deformation or detachment caused by stress concentration in traditional single-point connections, and significantly improving the overall rigidity of the B-pillar in side collisions. Through the redundant design of the multiple rows of snap-fit ​​connectors, even if some connectors loosen due to long-term vibration or extreme working conditions, other connectors can still maintain connection stability, forming multiple safety guarantees and reducing the risk of failure.

[0069] Of course, it is understandable that the snap-fit ​​part can be made of the same material as the interior panel 100 and be integrally formed. The snap-fit ​​part at this position can only install the interior panel 100 onto the liner 200. It has low requirements for structural strength and does not affect the complexity of the mold of the interior panel 100.

[0070] The interior panel 100 and the lining panel 200 are detachably connected by snap-fit ​​components, which facilitates later maintenance or partial replacement and reduces maintenance costs.

[0071] In one possible implementation, the same row of card connectors includes at least one of a first card connector 610, a second card connector 620, and a third card connector 630.

[0072] The first snap-fit ​​component 610 is a snap-fit ​​seat, which is inserted into the first snap-fit ​​hole 201 on the liner plate 200.

[0073] The second snap-fit ​​component 620 is a snap-fit ​​connector, which snaps into the second snap-fit ​​hole 202 on the liner plate 200.

[0074] The third connector 630 is a pin, which is inserted into the insertion slot 203 on the liner 200.

[0075] In the above embodiments, the snap-fit ​​seat, snap-fit ​​connector, and pin can all be manufactured using standard parts from mature technologies, which helps reduce R&D costs. When the snap-fit ​​seat is connected to the first snap-fit ​​hole 201, at least a portion of the snap-fit ​​seat's structure passes through the first snap-fit ​​hole 201, forming a snap-fit ​​structure. The snap-fit ​​connector can utilize its own elastic deformation to insert into the second snap-fit ​​hole 202, with a portion of the connector's structure located outside the second snap-fit ​​hole 202, forming a structural limit. The pin can be a boss with a guide surface or a structural rib. The pin is inserted into the insertion groove 203, providing a certain positioning and guiding function, facilitating the engagement of the first snap-fit ​​component 610 with the first snap-fit ​​hole 201, and promoting the engagement of the second snap-fit ​​component 620 with the second snap-fit ​​hole 202.

[0076] In specific implementation, this application does not restrict the arrangement order of the first card connector 610, the second card connector 620, and the third card connector 630 in the same row of card connectors. The same row of card connectors may include only one first card connector 610, only one second card connector 620, or only one third card connector 630. In addition, the same row of card connectors may include any two or all three of the first card connector 610, the second card connector 620, and the third card connector 630.

[0077] In the above embodiments, three types of snap-fit ​​connectors are used in combination within the same row, providing differentiated connection solutions for different liner 200 structures and stress requirements. For example, the snap-fit ​​seat adapts to the minute displacements of the body sheet metal through flexible deformation, absorbing vibration energy; the snap-fit ​​connector provides high-strength locking to prevent dislodgement; and the pin ensures the stability of the connection position, preventing loosening. This forms multiple safety guarantees. Even if one type of snap-fit ​​connector fails due to long-term vibration or extreme working conditions, the other types can still maintain connection stability, reducing the overall failure risk.

[0078] In one possible implementation, the multi-row connector includes a first row connector 640, a second row connector 650, and a third row connector 660; the third row connector 660 is located between the first row connector 640 and the second row connector 650 in the length direction of the interior panel 100.

[0079] Furthermore, the number of card connectors in the third row of card connectors 660 is greater than the number of card connectors in the first row of card connectors 640, and / or, the number of card connectors in the third row of card connectors 660 is greater than the number of card connectors in the second row of card connectors 650.

[0080] In the above embodiment, the third row of snap-fit ​​members 660 is located between the first and second rows, and its number of snap-fit ​​members is greater than that of the other rows. Since the B-pillar experiences the greatest impact force in the middle during a side collision, this design increases the density of connection points in key areas, distributing the impact force to more snap-fit ​​members, avoiding localized stress concentration, and significantly improving the connection stability between the interior panel 100 and the body sheet metal.

[0081] In one possible implementation, the fastener 300 includes a fixing part 310 and a reinforcing part 320.

[0082] The fixing part 310 is connected to the liner 200. The first end of the fixing part 310 is provided with a slot 311, which is used to engage with the body sheet metal.

[0083] The reinforcing part 320 connects the second end of the fixing part 310 and the liner 200, with the first end of the fixing part 310 and the second end of the fixing part 310 facing each other.

[0084] In practice, multiple fasteners 300 are provided. In the length direction of the liner 200, the fasteners 300 are arranged along the length direction of the liner 200, and fasteners 300 are provided on both sides of the length direction of the liner 200.

[0085] In the above embodiment, the slot 311 at the first end of the fixing part 310 engages with the body sheet metal to form a high-strength mechanical interlock, capable of withstanding significant shear and tensile forces. This significantly improves the stability of the B-pillar in side collisions. The reinforcing part 320 connects the second end of the fixing part 310 to the liner 200, transforming the concentrated force on the single fixing part 310 into a planar support, balancing the dynamic loads generated by body torsion or impact. This design reduces the risk of deformation or breakage of the fixing part 310 due to localized stress concentration.

[0086] The fixing part 310 and the reinforcing part 320 can be designed as an integral structure to improve the structural strength of the fixing part 300.

[0087] In one possible implementation, in order to improve the structural strength of the liner 200, a plurality of reinforcing ribs 700 are provided on the side of the liner 200 away from the interior panel 100, and the plurality of reinforcing ribs 700 are arranged along the length direction of the liner 200.

[0088] In one possible implementation, the liner 200 is provided with at least one positioning element 800, which is used to connect with positioning holes on the body sheet metal. The positioning element 800 and the positioning holes on the body sheet metal achieve rapid positioning through geometric matching, ensuring the initial alignment accuracy between the liner 200 and the body sheet metal.

[0089] In practice, the positioning component 800 can be a boss with a positioning pin, and the positioning hole can be a pre-punched hole or a molded groove. A tolerance adjuster can also be set on the positioning component 800 to adjust the gap between the liner 200 and the body sheet metal to ensure assembly accuracy.

[0090] In one possible implementation, this application provides a vehicle including a vehicle body and the aforementioned body pillar interior panel structure; the body pillar interior panel structure is connected to the body sheet metal of the vehicle body, wherein the body pillar interior panel structure has been described above and will not be repeated here. By providing a vehicle with the aforementioned body pillar interior panel structure, the complexity of the molds for manufacturing the parts required in the vehicle manufacturing process can be reduced, thereby reducing costs.

[0091] The embodiment of this application discloses a vehicle body pillar interior panel structure and its implementation principle as follows: The vehicle body pillar interior panel structure includes an interior panel 100 and a liner 200; the liner 200 is connected to the inner side of the interior panel 100 and adheres to the inner surface of the interior panel 100, supporting the interior panel 100; the liner 200 is provided with a fastener 300, which can be connected to the vehicle body sheet metal, and the interior panel 100 can be connected to the vehicle body sheet metal through the liner 200. By setting the liner 200, the liner 200 provides support for the interior panel 100, and the fastener 300 is integrated into the liner 200 rather than the interior panel 100, reducing the structural complexity of the interior panel 100. The interior panel 100 can focus on aesthetics and tactile experience, while the liner 200 focuses on mechanical performance and installation function. By setting the liner 200 on the inner side of the interior panel 100, rapid assembly can be achieved through adhesion or snap-fit, balancing functionality and design flexibility.
