Description

Technical Field

[0001] This invention relates to the technical field of door trim panel mounting structures, and more particularly to a door trim panel assembly. The invention also relates to vehicles comprising the aforementioned door trim panel assembly. Background Technology

[0002] Door trim panels, also known as door interior panels or door decorative panels, are a general term for the decorative structures and related components of vehicle doors, and are an important part of vehicle decoration. Door trim panels have multiple functions: by selecting panels with different colors, textures, and materials (such as plastic, leather, and fabric), they can provide a harmonious and aesthetically pleasing visual effect for the vehicle interior, playing an important role in enhancing the quality of the vehicle interior and the passenger's riding experience.

[0003] Since door trim panels typically cover the sheet metal structure of the door, they prevent the internal metal sheet metal structure from being directly exposed to the outside, reducing the risk of scratches and corrosion and protecting the internal sheet metal structure. They also conceal the internal mechanical structure and wiring harnesses, maintaining a clean and aesthetically pleasing interior. Furthermore, by filling the interior with sound-insulating and vibration-damping materials such as foam and sound-absorbing cotton, they reduce the transmission of external noise into the passenger compartment, improving its quietness.

[0004] Some door panels integrate various functional components, such as power window switches, door lock buttons, speakers, door handles, storage compartments, and cup holders, for the convenience of passengers. By incorporating impact-absorbing crumple zones within the panels, they can absorb the energy generated during a collision, protecting occupants from injury. In short, the design of door panel structures directly impacts the passenger experience and driving safety, making it a crucial aspect of vehicle design.

[0005] With the development of the automotive industry, vehicle styling is gradually moving towards personalization and uniqueness. Most car models opt to add door trim panels to enhance the overall design and aesthetics. Currently, considering factors such as stability, ease of operation, and production costs, common door trim panels are usually fixed to the door's sheet metal structure using methods such as clips, bolts, or structural adhesive.

[0006] Because some structures on the door trim panels are exposed to the elements for extended periods, they are prone to deformation due to high temperatures in summer. The connecting structures used to secure the door trim panels can experience pressure and friction against the panel itself due to uneven and irregular deformation of different parts. When the vehicle travels over bumpy roads, the areas subjected to this pressure and friction can produce abnormal noises due to the overall vibration of the vehicle. This phenomenon severely impacts the passenger experience and the overall perceived quality of the vehicle.

[0007] Therefore, as can be seen from the above existing technology, the current installation structure of the door trim panel is prone to squeezing and friction with the door trim panel after it deforms, which in turn causes abnormal noise from the door trim panel, affecting the passenger's riding experience and the overall quality perception of the vehicle. Summary of the Invention

[0008] In view of this, the present invention aims to provide a door trim panel assembly that can overcome the problem of squeezing and friction between the door trim panel and its related fixing structure after deformation, resulting in abnormal noise, thereby improving the passenger riding experience.

[0009] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0010] The present invention provides a door trim panel assembly, including a trim panel frame disposed on a door sheet metal, and an interior trim panel disposed on the inner side of the door sheet metal.

[0011] A snap-fit ​​structure is provided between the trim frame and the interior panel, the snap-fit ​​structure connecting the interior panel to the trim frame;

[0012] The snap-fit ​​structure includes a plurality of snap-fit ​​components arranged at intervals along the length direction of the interior panel. Each snap-fit ​​component includes a snap-fit ​​hole provided on one of the interior panel and the trim frame, and a snap-fit ​​block provided on the other of the interior panel and the trim frame.

[0013] The plurality of said snap-fit ​​components are configured as a first snap-fit ​​component and a plurality of second snap-fit ​​components located at the ends of the arrangement. The first snap-fit ​​component includes a first snap-fit ​​block and a first snap-fit ​​hole. The first snap-fit ​​block abuts against the inner wall of the first snap-fit ​​hole in the length direction of the interior panel to limit the displacement of the interior panel along the length direction of the trim panel frame.

[0014] Furthermore, the snap-fit ​​block includes a main body, snap-fit ​​heads and support ribs disposed on two opposite sides of the main body, and the support ribs are provided with a support slope on the side away from the main body;

[0015] Part of the main body is inserted into the snap-fit ​​hole, and the snap-fit ​​head engages with one side of the snap-fit ​​hole to prevent the main body from coming out of the snap-fit ​​hole. The supporting inclined surface abuts against the hole wall of the snap-fit ​​hole to limit the insertion depth of the main body.

[0016] Furthermore, the main body is provided with a notch, which is provided along the edge of the card head, and the card head is provided on the main body in a cantilever shape.

[0017] Furthermore, each end of the first snap-fit ​​block is provided with a protruding limiting rib, and each limiting rib abuts against the wall of the snap-fit ​​hole to limit the displacement of the interior panel along the length direction of the trim panel frame.

[0018] Furthermore, the trim panel frame has a mounting portion located below the door sheet metal, the mounting portion protruding inwards from the door sheet metal;

[0019] The snap-fit ​​structure is located between the mounting portion and the interior panel.

[0020] Furthermore, the trim panel frame is provided with a plurality of buckles spaced apart along its own length, the buckles being connected to the door sheet metal; and / or,

[0021] The trim panel frame is equipped with a spring nut, which is bolted to the door sheet metal.

[0022] Furthermore, it also includes an outer trim panel disposed on the trim panel frame;

[0023] The trim frame is located on the outside of the door sheet metal, and the outer trim panel covers the outside of the trim frame.

[0024] Furthermore, the outer trim panel has a bottom portion located below the trim panel frame, and an upwardly extending flange is provided on the bottom portion. The flange is located inside the trim panel frame, and an insertion structure is provided between the flange and the trim panel frame.

[0025] The plug-in structure plugs the flange and the trim panel frame together along the left-right direction of the vehicle and can limit the downward displacement of the outer trim panel along the vertical direction of the vehicle.

[0026] Furthermore, the bottom of the interior trim panel is connected to the bottom portion; and / or,

[0027] The exterior trim panel includes an exterior trim panel body and a bright strip disposed on the upper part of the exterior trim panel body. The exterior trim panel body is detachably connected to the trim panel frame. Compared with the prior art, the present invention has the following advantages:

[0028] The door trim panel assembly and vehicle described in this invention, through the setting of the snap-fit ​​structure between the interior panel and the trim panel frame, can change the deformation of the trim panel from overall to local control. Except for the rear positioning point, the other positions can be avoided, which can avoid the problem of trim panel deformation, squeezing and abnormal noise caused by heat in traditional models, and thus improve the riding experience of passengers.

[0029] Furthermore, the trim panel frame is fixedly installed on the sheet metal structure of the door and used to connect with the door sheet metal structure to form a fixed whole, which can provide better support for the interior trim panel, thereby achieving a better visual effect and higher mechanical load-bearing capacity and deformation resistance. At the same time, the trim panel frame can also increase the mechanical strength of the door sheet metal structure, making the door sheet metal structure less likely to deform or be damaged in a collision.

[0030] The interior panel cover is attached to the trim frame, and together with the trim frame, it forms a protective shielding structure for the door sheet metal structure. In addition to preventing the door sheet metal structure from being exposed to the outside and improving the overall aesthetics, it also helps to reduce the scratches and corrosion that the door sheet metal structure may suffer from direct exposure to the outside.

[0031] The snap-fit ​​structure is positioned between the trim panel frame and the interior panel to fix the relative position of the interior panel and the trim panel frame, thus limiting the position of the interior panel by the trim panel frame. By configuring the snap-fit ​​structure as multiple snap-fit ​​components along the length of the interior panel, a snap-fit ​​structure is provided at regular intervals along the length of the interior panel to limit and fix it, thereby providing better limiting and support for the interior panel. By configuring the snap-fit ​​components as a structure in which snap-fit ​​blocks and snap-fit ​​holes cooperate with each other, the difficulty of installing and disassembling the snap-fit ​​components can be effectively reduced, making the installation and disassembly processes easier to operate.

[0032] Secondly, by configuring a first snap-fit ​​assembly located at the beginning or end of the entire arrangement, and a plurality of second snap-fit ​​assemblies arranged before or after the first snap-fit ​​assembly, the interior trim panel can be limited and fixed in different directions respectively. The first snap-fit ​​assembly includes a first snap-fit ​​block and a first snap-fit ​​hole. The two edges of the first snap-fit ​​block along the length of the interior trim panel abut against the inner wall of the first snap-fit ​​hole, thereby limiting the first snap-fit ​​block along the length of the interior trim panel and preventing the interior trim panel from displacing along its own length.

[0033] The multiple second snap-fit ​​components, besides the first snap-fit ​​component, do not restrict the position of the interior trim panel along its length. When the interior trim panel or trim frame deforms due to heat exposure to high ambient temperatures, the single first snap-fit ​​component, located only at the beginning or end of the multiple snap-fit ​​components, restricts the position of the interior trim panel along its length. This transforms the installation and positioning structure of the interior trim panel from a multi-point overall control structure in the prior art to a single-point local control structure. Therefore, it significantly reduces the possibility of the interior trim panel or trim frame being squeezed and rubbed after heat deformation due to exposure to high ambient temperatures, thus achieving the invention's objective of overcoming the problem of squeezing and rubbing against the related fixing structure after the door trim panel deforms, improving the passenger riding experience, and enhancing the overall quality perception of the vehicle.

[0034] Since both the first and second snap-fit ​​components can limit the interior panel along its thickness and width, they provide stable support and restraint, preventing misalignment between the interior panel and the trim frame due to vehicle movement or bumps. By placing the snap-fit ​​blocks and snap-fit ​​holes on the trim frame and interior panel respectively, or on the interior panel or trim frame respectively, this application allows for different distribution and installation methods depending on the specific shape, size, and purpose of the trim frame, interior panel, and door sheet metal structure, thereby expanding the applicability of this application.

[0035] Furthermore, by setting the snap-fit ​​block as a combined structure consisting of a main body, a snap-fit ​​head, and a support rib, the fixing effect of the snap-fit ​​block can be further optimized. The main body of the snap-fit ​​block, as the primary structure, provides support and restraint for the other structural components. The snap-fit ​​head structure on the main body abuts against the end face of the snap-fit ​​hole, thus restraining the interior panel's position along its height and width, preventing the snap-fit ​​block from detaching from the snap-fit ​​hole, and firmly pressing the interior panel and trim frame together. The support rib enhances the structural strength and deformation resistance of the connection between the snap-fit ​​block and the interior panel or trim frame, allowing the snap-fit ​​block to withstand stronger loads without breaking. The support rib has a supporting ramp that abuts against the wall of the snap-fit ​​hole, limiting the depth to which the main body is inserted into the restraining hole, thereby preventing wobbling and rattling between the interior panel and trim frame, ultimately improving the passenger experience.

[0036] By providing notches distributed along the edge of the clip head on the main body, the clip head can be attached to the main body in a cantilever form. This allows the clip head on the main body to generate a greater displacement along the thickness direction of the main body under a certain pressure, making it easier for the clip head to enter the snap-fit ​​hole and snap onto the other side of the snap-fit ​​hole. This achieves the invention objective of reducing installation difficulty and improving the operability of this application.

[0037] Furthermore, by setting outwardly protruding limiting ribs at both ends of the first locking block, and ensuring that these limiting ribs abut against the inner wall of the first locking hole, not only can the interior panel be limited along its own length, but the structural strength and load-bearing capacity of the first locking block itself can also be improved, making it less prone to deformation and breakage, thus enhancing the stability of its positional limitation effect on the interior panel. The overall structure is simple and easy to manufacture and implement.

[0038] By incorporating a mounting portion protruding inwards from the door sheet metal on the trim panel frame, the mounting portion provides a location for the snap-fit ​​components, facilitating the snap-fit ​​connection between the trim panel frame and the interior trim panel. Furthermore, by designing the mounting portion to protrude inwards from the door sheet metal structure, the structural strength and load-bearing capacity of the trim panel frame itself are enhanced, making it less prone to deformation and breakage under load, thus improving the stability of the snap-fit ​​structure between the trim panel frame and the interior trim panel.

[0039] By incorporating clips on the trim panel frame, the frame is fixed in position to the door sheet metal structure, thus defining the frame's position. A spring-loaded nut and bolt connection structure between the trim panel frame and the door sheet metal structure, working in conjunction with the clips, further secures their relative positions. The specific connection and fixing structures and their distribution can be selected based on the shape and size of the door sheet metal structure, trim panel frame, and interior trim panels. The overall structure is robust, easy to operate, and widely applicable.

[0040] Finally, by setting an outer trim panel on the trim panel frame, the outer trim panel can cover the trim panel frame and the door sheet metal structure. This not only improves the protection of the door sheet metal structure and trim panel frame, which helps to prevent the door sheet metal structure from being scratched or corroded due to exposure to the outside, but also improves the decorative effect of the door trim panel assembly and enhances the overall aesthetics of the door.

[0041] By adding a flange to the bottom of the exterior trim panel, not only is the structural strength of the trim panel itself enhanced, but it can also be used to install a connecting structure. This connecting structure improves the stability and reliability of the trim panel mounted on the trim frame, helping to prevent the trim panel from shaking or detaching during vehicle movement and bumps. Connecting the bottom of the interior trim panel to the bottom of the exterior trim panel creates a seamless whole, encasing the door sheet metal and enhancing the decorative effect of the interior and exterior trim panels on the door sheet metal structure. Adding a bright strip to the exterior trim panel further improves its overall appearance. By making the bright strip a detachable connection structure with the exterior trim panel, installation and removal of the bright strip are convenient, simplifying the installation and subsequent maintenance and repair of the exterior trim panel.

[0042] The present invention also proposes a vehicle in which the door is provided with the door trim panel assembly as described above.

[0043] The vehicle described in this invention has the same beneficial effects as the aforementioned door trim assembly, and will not be repeated here. Attached Figure Description

[0065] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0066] In the description of this invention, it should be noted that the use of terms such as "upper," "lower," "inner," and "outer," indicating orientation or positional relationship, is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing the invention and simplifying the description. It does 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, and therefore should not be construed as a limitation of the invention. Furthermore, the use of terms such as "first" and "second" is also for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0067] Taking a door trim panel assembly and vehicle described in this invention as an example, the directional terms used in the embodiments, such as "up," "down," "left," "right," "front," and "rear," are defined based on the vehicle's vertical direction (also known as the height direction, or the vehicle's Z-direction), horizontal direction (also known as the width direction, or the vehicle's Y-direction), and front-back direction (also known as the length direction, or the vehicle's X-direction). "Inner" and "outer" are defined based on the outline of the corresponding component. For example, "inner" and "outer" are defined based on the vehicle's outline, with the side of the vehicle outline closer to the center of the vehicle being "inner," and vice versa.

[0068] Furthermore, in the description of this invention, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0069] The following will refer to the appendix. Figure 1 To be continued Figure 6 The present invention will be described in detail with reference to the embodiments.

[0070] Example 1

[0071] This embodiment relates to a door trim panel assembly, which includes an interior trim panel, a trim panel frame, and a snap-fit ​​structure for fixing the relative position between the trim panel frame and the interior trim panel.

[0072] Furthermore, the door trim panel assembly in this embodiment improves the snap-fit ​​structure used to fix the relative position between the trim panel frame and the interior trim panel from the existing overall control structure containing multiple fixed support points to a local control structure with a single fixed support point. This provides space for irregular deformation of the interior trim panel and trim panel frame caused by excessively high ambient temperature or other reasons, thereby overcoming the problem of squeezing and rubbing against the related fixing structure after the door trim panel deforms and generating abnormal noise, and improving the passenger riding experience and the overall quality of the vehicle.

[0073] In terms of overall structure, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The door trim panel assembly of this embodiment includes a trim panel frame 1, an interior trim panel 2, and a snap-fit ​​structure. The trim panel frame 1 is fixedly installed on the door sheet metal structure 9, and the trim panel frame 1 provides support and limits the installation of the interior trim panel 2. The snap-fit ​​structure is disposed between the interior trim panel 2 and the trim panel frame 1 to define the position between the interior trim panel 2 and the trim panel frame 1. The snap-fit ​​structure is configured as multiple snap-fit ​​components distributed along the length direction of the interior trim panel 2. The multiple snap-fit ​​components are arranged along the length direction of the interior trim panel 2 and are divided into first snap-fit ​​components 3 arranged at the beginning or end, and second snap-fit ​​components 4 arranged at other positions.

[0074] Each snap-fit ​​assembly consists of a snap-fit ​​block and a snap-fit ​​hole. The snap-fit ​​block snaps into the snap-fit ​​hole, thereby defining the position of the interior panel 2. The difference between the first snap-fit ​​assembly 3 and the second snap-fit ​​assembly 4 is that the first snap-fit ​​assembly 3 includes a first snap-fit ​​block 301 and a first snap-fit ​​hole 302.

[0075] The two ends of the first latching block 301 abut against the two side walls of the first latching hole 302 along the length of the interior panel 2. Therefore, the interior panel 2 is limited along its own length due to the abutment structure between the first latching block 301 and the first latching hole 302. Under normal conditions, the interior panel 2 will not undergo relative displacement with the trim frame 1 along its own length. In addition, both the first latching assembly 3 and the second latching assembly 4 can limit the position of the interior panel 2 along the width and height of the vehicle.

[0076] As described above, the trim panel frame 1 is fixedly installed on the door sheet metal structure 9 to form a fixed whole with the door sheet metal structure 9, thereby providing better support for the interior trim panel 2, achieving a better visual effect and higher mechanical load-bearing capacity and deformation resistance. The trim panel frame 1 also increases the mechanical strength of the door sheet metal structure 9, making the door sheet metal structure 9 less prone to deformation or damage in a collision.

[0077] The interior panel 2 is attached to the trim frame 1, and together with the trim frame 1, it forms a protective shielding structure for the door sheet metal structure 9. In addition to preventing the door sheet metal structure 9 from being exposed to the outside and improving the overall aesthetics, it also helps to reduce the scratches and corrosion that the door sheet metal structure 9 may suffer from direct exposure to the outside.

[0078] A snap-fit ​​structure is positioned between the trim frame 1 and the interior panel 2 to fix the relative position of the interior panel 2 and the trim frame 1, thus limiting the position of the interior panel 2 by the trim frame 1. By configuring the snap-fit ​​structure as multiple snap-fit ​​components along the length of the interior panel 2, a snap-fit ​​structure is provided at regular intervals along the length of the interior panel 2 to limit and fix it, thereby providing better positioning and support for the interior panel 2. By configuring the snap-fit ​​components as a structure where snap-fit ​​blocks and snap-fit ​​holes cooperate, the difficulty of installing and disassembling the snap-fit ​​components is effectively reduced, making the installation and disassembly processes easier to operate.

[0079] When the interior panel 2 or the trim frame 1 undergoes irregular deformation due to exposure to the outside environment or excessively high ambient temperature, only the first snap-fit ​​component 3 limits the interior panel 2 along its length direction. The other multiple second snap-fit ​​components 4 in the snap-fit ​​structure do not limit the interior panel 2 along its length direction and provide a deformation gap for its irregular deformation along its own length direction. This reduces the squeezing and deformation caused by deformation of the connection structure between the trim frame 1 and the interior panel 2, thereby reducing abnormal noise, improving the passenger riding experience and the overall vehicle quality experience.

[0080] The aforementioned structure provides localized control over the relative position between the interior panel 2 and the trim frame 1. This ensures the stability of their relative position under normal conditions while reducing abnormal noises caused by deformation of either the interior panel 2 or the trim frame 1. Compared to existing technologies that typically use multiple points to achieve overall relative position control, this structure is simpler, easier to implement, and significantly more effective in reducing abnormal noises.

[0081] By configuring a first snap-fit ​​assembly 3 located at the beginning or end of the entire arrangement, and a plurality of second snap-fit ​​assemblies 4 arranged before or after the first snap-fit ​​assembly 3, the interior panel 2 can be limited and fixed in different directions respectively. The first snap-fit ​​assembly 3 includes a first snap-fit ​​block 301 and a first snap-fit ​​hole 302. The two sides of the first snap-fit ​​block 301 along the length of the interior panel 2 abut against the inner wall of the first snap-fit ​​hole 302, so that the inner wall of the first snap-fit ​​hole 302 limits the first snap-fit ​​block 301 along the length of the interior panel 2, thereby preventing the interior panel 2 from displacing along its own length.

[0082] The multiple second snap-fit ​​components 4, besides the first snap-fit ​​component 3, do not restrict the position of the interior panel 2 along its own length. When the interior panel 2 or the trim frame 1 deforms due to heat exposure to the outdoors or excessively high ambient temperature, the single first snap-fit ​​component 3, located only at the beginning or end of the multiple snap-fit ​​components, restricts the position of the interior panel 2 along its length. This changes the installation and positioning structure of the interior panel 2 from a multi-point overall control structure in the prior art to a single-point local control structure. Therefore, it greatly reduces the possibility of the interior panel 2 or the trim frame 1 being squeezed and rubbed and producing abnormal noise after being exposed to the outdoors or excessively high ambient temperature and deforming. This achieves the invention objective of overcoming the problem of squeezing and rubbing between the door trim panel and its related fixing structure after deformation, improving the passenger riding experience, and enhancing the overall quality of the vehicle.

[0083] Furthermore, since both the first snap-fit ​​component 3 and the second snap-fit ​​component 4 can limit the interior panel 2 along its own thickness direction (i.e., the vehicle height direction) and width direction (i.e., the vehicle width direction), they can provide stable support and limit the interior panel 2, which helps to prevent the interior panel 2 from misaligning with the trim frame 1 due to vehicle movement or bumps. By setting the snap-fit ​​blocks and snap-fit ​​holes on the trim frame 1 and the interior panel 2 respectively, or on the interior panel 2 or the trim frame 1 respectively, this application can select different distribution and installation forms according to the specific shape, size, and purpose of the trim frame 1, the interior panel 2, and the door sheet metal structure 9, thereby expanding the applicability of this application.

[0084] Based on the above design concept, specifically, in this embodiment, referring to Figure 2 , Figure 4 and Figure 5 The snap-fit ​​components are configured as a plurality of components distributed along the length of the interior panel 2. Each snap-fit ​​component includes a snap-fit ​​block and snap-fit ​​holes. The snap-fit ​​components are divided into first snap-fit ​​components 3 arranged at the beginning or end, and second snap-fit ​​components 4 arranged at other positions. In this embodiment, the first snap-fit ​​components 3 are located at the end of the arrangement.

[0085] Reference Figure 2 , Figure 4 and Figure 5The snap-fit ​​block, used to form the snap-fit ​​assembly, extends from the interior panel 2 towards the trim frame 1. The snap-fit ​​block includes a main body 5, a snap-fit ​​head 6, and a support rib 7. The main body 5 is a plate-like structure extending from the interior panel 2 towards the trim frame 1. The included angle between the planes containing the two sides of the main body 5 is 3 degrees. By providing a plate-like structure with a 3-degree included angle between the planes containing the two sides of the main body 5, the structural stability of the main body 5 after insertion into the snap-fit ​​hole is improved, reducing the possibility of the snap-fit ​​block detaching from the snap-fit ​​hole. The higher side of the main body 5 in the overall vehicle height direction has a support rib 7. The wall thickness of the support rib 7 is 1.2 mm. The cross-section of the support rib 7 is a right-angled triangle. The plane containing the hypotenuse of the right-angled triangle in the cross-section of the support rib 7 is the supporting inclined surface 701 of the support rib 7. The supporting inclined surface 701 of the support rib 7 is in contact with the plane containing the highest inner wall in the overall vehicle height direction of the snap-fit ​​hole. Multiple support ribs 7 can be provided. In this embodiment, for the sake of ease of installation and design and production costs, the support ribs 7 are constructed as two that are symmetrically distributed about the geometric center of the main body 5.

[0086] By setting the snap-fit ​​block as a combination structure consisting of the main body 5, the snap-fit ​​head 6 and the support rib 7, the fixing effect of the snap-fit ​​block can be further optimized.

[0087] The main body 5 of the snap-fit ​​block serves as the primary structure, providing support and limiting for the other structural components. The snap-fit ​​head 6 on the main body 5 abuts against the end face of the trim panel frame 1 with snap-fit ​​holes, thus limiting the position of the interior trim panel 2 along its height and width, preventing the snap-fit ​​block from dislodging from the snap-fit ​​holes, and firmly pressing the interior trim panel 2 and trim panel frame 1 together. The support rib 7 enhances the structural strength and deformation resistance of the connection between the snap-fit ​​block and the interior trim panel 2 or trim panel frame 1, allowing the snap-fit ​​block to withstand stronger loads without breaking. The support rib 7 has a support slope 701, which abuts against the wall of the snap-fit ​​hole, limiting the depth to which the main body 5 is inserted into the limiting hole, thereby preventing shaking and abnormal noise between the interior trim panel 2 and trim panel frame 1, and improving the passenger experience.

[0088] Reference Figure 2 , Figure 4 and Figure 5 The snap-fit ​​hole can be a long rectangular hole parallel to the length of the interior trim panel 2 and formed on the trim panel frame 1. The snap-fit ​​hole is 24mm long and 5mm wide.

[0089] The planes containing the two side walls of the snap-fit ​​hole along the overall vehicle height direction are non-parallel planes. The lower plane is parallel to the horizontal plane, while the higher plane is set at a certain angle to the horizontal plane, so that it can fit against the support slope 701.

[0090] The structural design of the snap-fit ​​hole causes the opening area of ​​the snap-fit ​​hole to gradually decrease along the direction away from the center of the vehicle body. By setting the highest inner wall of the snap-fit ​​hole along the height direction of the vehicle body as an inclined plane that can fit with the support slope 701 of the support rib 7, the depth of the main body 5 inserted into the snap-fit ​​hole can be limited, thereby providing a limit for the interior panel 2 along the height direction of the vehicle body.

[0091] In addition, the support rib 7 can improve the connection strength and deformation resistance between the snap-fit ​​block and the interior panel 2 or the trim frame 1, so that the snap-fit ​​block can withstand stronger loads without breaking.

[0092] Reference Figure 2 , Figure 4 and Figure 5 In order for the main body 5 to be snapped into the snap-fit ​​hole, snap heads 6 are formed on both sides of the main body 5 extending in the height direction of the whole vehicle. The cross-sectional shape of the snap heads 6 is U-shaped. The wall thickness of the snap heads 6 is 1mm. The end face of the snap heads 6 abuts against the end face of the trim panel frame 1 where the snap-fit ​​hole is opened, thereby limiting the interior trim panel 2 along the width direction of the whole vehicle.

[0093] To improve the smoothness of the insertion of the main body 5 into the locking hole and reduce installation difficulty, a notch 501 is also provided on the main body 5 in this embodiment. The notch 501 is distributed along the outer side of the locking head 6 and is constructed in a "U" shape along the outer edge of the projection of the locking head 6 onto the main body 5. Due to the notch 501 on the main body 5, the locking head 6 forms a cantilever shape with only one end connected to the main body 5. Since the connection length between the locking head 6 and the main body 5 is reduced, under the same force, the locking head 6 with the above structure can generate more displacement in the thickness direction of the main body 5 itself. That is to say, the locking head 6 is easier to push into and lock into the locking hole.

[0094] Furthermore, to facilitate the entry of the main body 5 into the snap-fit ​​hole and to ensure that the snap-fit ​​head 6 abuts against the end face of the trim frame 1 with the snap-fit ​​hole, the side of the snap-fit ​​head 6 that contacts the inner wall of the snap-fit ​​hole is constructed as a slope with a gradually decreasing thickness along the width direction of the vehicle body away from the center. This slope, which guides the bending deformation of the snap-fit ​​head 6 during its entry into the snap-fit ​​hole, improves the smoothness of the snap-fit ​​head 6's entry.

[0095] In order to define the position of the interior panel 2 along its own length, refer to Figure 5 The first card-connecting component 3 includes a first card-connecting block 301 and a first card-connecting hole 302.

[0096] The first snap-fit ​​block 301 also has the same structure as the snap-fit ​​block used to construct the second snap-fit ​​assembly 4, including a main body 5, a snap-fit ​​head 6, and a support rib 7. The main body 5 is a plate-like structure extending from the interior trim panel 2 towards the trim panel frame 1. The included angle between the planes containing the two sides of the main body 5 is 3 degrees. By providing a plate-like structure with an included angle of 3 degrees between the planes containing the two sides of the main body 5, the possibility of the first snap-fit ​​block 301 dislodging from the first snap-fit ​​hole 302 can be reduced, and the overall structural stability of the first snap-fit ​​assembly 3 can be improved. The higher side of the main body 5 in the height direction of the vehicle has a support rib 7.

[0097] In this embodiment, the wall thickness of the support rib 7 is 1.2 mm. The cross-section of the support rib 7 is a right-angled triangle. The plane containing the hypotenuse of the right-angled triangle in the cross-section of the support rib 7 is the supporting inclined surface 701 of the support rib 7. The supporting inclined surface 701 of the support rib 7 is in contact with the plane containing the highest inner wall of the first snap-fit ​​hole 302 in the overall vehicle height direction. Multiple support ribs 7 can be provided. In this embodiment, for the sake of ease of installation and design and production costs, the support ribs 7 are constructed as two symmetrically distributed about the geometric center of the main body 5.

[0098] Reference Figure 5 The first snap-fit ​​hole 302 can be a long rectangular hole parallel to the length of the interior trim panel 2 and formed on the trim panel frame 1. The length of the first snap-fit ​​hole 302 is 24mm and the width is 5mm. The planes containing the two side walls of the first snap-fit ​​hole 302 along the height direction of the vehicle are non-parallel planes. The lower plane is parallel to the horizontal plane, and the higher plane is set at a certain angle to the horizontal plane, so that it can fit with the supporting inclined surface 701, and the opening area of ​​the first snap-fit ​​hole 302 gradually decreases along the direction away from the center of the vehicle body.

[0099] By setting the highest inner wall of the first snap-fit ​​hole 302 along the vehicle height direction as an inclined plane that can fit into the support slope 701 of the support rib 7, the depth of the main body 5 inserted into the first snap-fit ​​hole 302 can be limited, thereby providing a limit for the interior panel 2 along the vehicle height direction. In addition, the setting of the support rib 7 can improve the connection structure strength and deformation resistance between the first snap-fit ​​block 301 and the interior panel 2 or the trim frame 1, so that the first snap-fit ​​block 301 can withstand stronger loads without breaking.

[0100] Reference Figure 5In order for the main body 5 to be snapped into the first snap-fit ​​hole 302, snap heads 6 are formed on both sides of the main body 5 extending in the height direction of the entire vehicle. The cross-sectional shape of the snap heads 6 is U-shaped. The wall thickness of the snap heads 6 is 1mm. The end face of the snap heads 6 abuts against the end face of the trim panel frame 1 where the first snap-fit ​​hole 302 is opened, thereby limiting the interior trim panel 2 along the width direction of the entire vehicle.

[0101] To improve the smoothness of the process of the main body 5 entering the first snap-fit ​​hole 302 and reduce the installation difficulty, in this embodiment, a notch 501 is also provided on the main body 5. The notch 501 is distributed along the outer side of the snap-fit ​​head 6 and is constructed in a "U" shape distributed along the outer edge of the projection of the snap-fit ​​head 6 onto the main body 5. Due to the notch 501 on the main body 5, the snap-fit ​​head 6 forms a cantilever shape with only one end connected to the main body 5. Since the connection length between the snap-fit ​​head 6 and the main body 5 is reduced, under the same force, the snap-fit ​​head 6 with the above structure can generate more displacement in the thickness direction of the main body 5 itself. That is to say, the snap-fit ​​head 6 is easier to push into and snap into the first snap-fit ​​hole 302.

[0102] Furthermore, to facilitate the entry of the main body 5 into the first latching hole 302 and to allow the latch head 6 to abut against the end face of the trim frame 1 with the first latching hole 302, the side of the latch head 6 that contacts the first latching hole 302 is constructed as a slope with a gradually decreasing thickness along the width direction of the vehicle body away from the center. The slope that contacts the inner wall of the first latching hole 302 can guide the bending deformation of the latch head 6 during its entry into the latching hole, thereby improving the smoothness of the latch head 6's entry into the latching hole.

[0103] Reference Figure 5 Since the main body 5, the latch head 6, and the supporting rib 7 constituting the first latching block 301 are structurally and functionally identical to those constituting the latching block of the second latching assembly 4, they will not be described in detail here. The difference between the first latching block 301 and the latching block constituting the second latching assembly 4 lies in the fact that the first latching block 301 has two limiting ribs 303 symmetrically arranged about its own center on both sides. The limiting ribs 303 have a triangular cross-section, extending from the first latching block 301 to both sides, and abut against two side walls distributed along the length direction of the interior panel 2 (i.e., the overall vehicle length direction) of the first latching hole 302.

[0104] Because the first snap-fit ​​block 301 has a limiting rib 303, it forms a limiting relationship with the trim frame 1, which has a first snap-fit ​​hole 302, along the length of the interior panel 2, thus ensuring the stability of the position between the interior panel 2 and the trim frame 1. The limiting block used to form the second snap-fit ​​assembly 4 does not have a limiting rib 303, resulting in a gap between the snap-fit ​​block used to form the second snap-fit ​​assembly 4 and its corresponding snap-fit ​​hole along the opposite length of the interior panel 2. This gap provides space for uneven deformation of the interior panel 2 or trim frame 1 due to exposure to the outside and high temperatures, reducing the squeezing and friction between the interior panel 2 or trim frame 1 and its connecting limiting part, and reducing the possibility of abnormal noise from the interior panel 2 or trim frame 1.

[0105] It should be noted that, in this embodiment, the first snap-fit ​​block 301 used to form the first snap-fit ​​assembly 3 and the other snap-fit ​​blocks used to form the second snap-fit ​​assembly 4 are all formed on the interior panel 2 by injection molding. The first snap-fit ​​hole 302 used to form the first snap-fit ​​assembly 3 and the other snap-fit ​​holes used to form the second snap-fit ​​assembly 4 are all opened on the trim panel frame 1 along the length direction of the interior panel 2.

[0106] However, the above structure does not constitute a limitation on the arrangement form and position of the first snap-fit ​​component 3 and the second snap-fit ​​component 4. In the embodiments of this application, the first snap-fit ​​component 3 and the second snap-fit ​​component 4 can also change the arrangement position of the snap-fit ​​block and the distribution position of the snap-fit ​​hole according to actual needs to achieve the best effect.

[0107] Reference Figure 2 and Figure 3 To improve the support effect of the trim panel frame 1 on the snap-fit ​​structure, in this embodiment, the trim panel frame 1 is provided with a mounting portion 101 protruding into the inner side of the door sheet metal structure 9. Because the mounting portion 101 provides a position for the snap-fit ​​components, it facilitates the snap-fit ​​connection between the trim panel frame 1 and the interior panel 2. By configuring the mounting portion 101 as a structure protruding into the inner side of the door sheet metal structure 9, the structural strength and load-bearing capacity of the trim panel frame 1 itself can be further improved, making it less prone to deformation and breakage under load, thereby improving the stability of the snap-fit ​​structure between the trim panel frame 1 and the interior panel 2.

[0108] Reference Figure 2 and Figure 3To securely fasten the trim panel frame 1 to the door sheet metal structure 9, in this embodiment, the trim panel frame 1 is further provided with a clip 102 and a spring nut 103. The trim panel frame 1 is fixed in relative position to the body sheet metal structure via the clip 102 and the spring nut 103. A stud is threaded onto the spring nut 103 to engage with it. The stud passes through both the spring nut 103 and the body sheet metal structure. By providing the clip 102 on the trim panel frame 1, the trim panel frame 1 can form a fixed overall structure with the door sheet metal structure 9 under the action of the clip 102, thereby limiting the position of the trim panel frame 1 itself.

[0109] By setting a spring nut 103 and a stud threaded connection between the trim panel frame 1 and the door sheet metal structure 9, the relative position between the door sheet metal structure 9 and the trim panel frame 1 can be fixed in conjunction with the clip 102. The specific connection and fixing structure and distribution method can be selected according to the shape and size of the door sheet metal structure 9, the trim panel frame 1 and the interior panel 2. The overall structure is sturdy, easy to operate and has a wide range of applications.

[0110] Reference Figure 1 and Figure 6 To further enhance the overall appearance of this application, this embodiment also includes an outer trim panel 8 disposed on the trim panel frame 1. The outer trim panel 8 has a bottom portion 801 located below the trim panel frame 1. A flange 802 extends upward along the height direction of the vehicle on the bottom portion 801. The flange 802 is located inside the trim panel frame 1, and a connecting structure 803 is provided between the flange 802 and the trim panel frame 1. The connecting structure 803 includes a connecting hole and a pin. In this embodiment, the pin is formed inside the trim panel frame 1, and the connecting hole is formed on the flange 802 along the thickness direction and corresponds to the position of the pin. Multiple connecting structures 803 are arranged along the length direction of the outer trim panel 8.

[0111] It should be noted that the distribution and matching form of the pins and holes in the above-mentioned plug-in structure 803 do not constitute a limitation on the construction form of the plug-in structure 803. The specific distribution form of the plug-in structure 803 can also be adjusted according to actual needs, such that the pins are distributed on the flange 802, and the holes are opened on the decorative panel frame 1.

[0112] Furthermore, the bottom of the interior trim panel 2 extends towards the bottom portion 801 of the exterior trim panel 8 and abuts against it. By setting the exterior trim panel 8 on the trim panel frame 1, the exterior trim panel 8 can cover the trim panel frame 1 and the door sheet metal structure 9, which can improve the protection of the door sheet metal structure 9 and the trim panel frame 1, and help avoid scratches or corrosion of the door sheet metal structure 9 due to exposure to the outside. It can also improve the decorative effect of the door trim panel assembly and enhance the overall aesthetics of the door.

[0113] By providing a flange 802 at the bottom portion 801 of the exterior trim panel 8, the structural strength of the exterior trim panel 8 is improved, and a connecting structure 803 can also be provided. The connecting structure 803 improves the stability and reliability of the exterior trim panel 8 mounted on the trim panel frame 1, helping to prevent the exterior trim panel 8 from shaking or falling off due to vehicle movement and bumps. By connecting the bottom of the interior trim panel 2 to the bottom portion 801 of the exterior trim panel 8, the interior trim panel 2 and the exterior trim panel 8 can form a continuous whole, covering the door sheet metal structure 9 inside, thereby improving the decorative effect of the interior trim panel 2 and the exterior trim panel 8 on the door sheet metal structure 9.

[0114] Reference Figure 1 and Figure 6 The exterior trim panel 8 includes an exterior trim panel 8 body and a bright strip 805 mounted on the top of the exterior trim panel 8 body. The bright strip 805 is detachably connected to the exterior trim panel 8 body by bolts.

[0115] By installing a bright strip 805 on the exterior trim panel 8, the overall appearance of the exterior trim panel 8 can be further enhanced. By setting the bright strip 805 as a detachable connection structure with the exterior trim panel 8, the installation and removal of the bright strip 805 can be facilitated, simplifying the installation of the exterior trim panel 8 and subsequent maintenance and repair work.

[0116] Example 2

[0117] This embodiment relates to a vehicle in which the door trim panel assembly of Embodiment 1 is installed on the door.

[0118] In this embodiment, the vehicle has the aforementioned door trim panel assembly installed on its doors. By improving the snap-fit ​​structure used to fix the relative position between the trim panel frame and the interior trim panel from the existing overall control structure containing multiple fixed support points to a local control structure with a single fixed support point, space is reserved for irregular deformation of the interior trim panel and trim panel frame caused by excessively high ambient temperature or other reasons. This can overcome the problem of squeezing and rubbing against the related fixing structure after the door trim panel deforms, which can generate abnormal noise and help improve the passenger riding experience.

[0119] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
