Description

Technical Field

[0001] This application belongs to the field of vehicle integrated component technology, and more specifically, relates to an integrated decorative panel assembly and a vehicle. Background Technology

[0002] With the continuous upgrading of the automotive consumer market, consumers have placed higher demands on the functionality and styling sophistication of car interiors. To meet diverse functional needs, car interiors typically require multiple independent components such as inward-opening door handles, speakers, and ambient lighting within a limited space. This makes the styling of interior trim parts increasingly complex, requiring not only individual design of the installation structure and appearance for each component, but also coordination of the layout between them. This results in a fragmented overall visual presentation of the interior, and the installation of individual components complicates the assembly process. In addition to increasing the complexity of mold development and manufacturing, it also makes it difficult to achieve a unified styling style, thus hindering the improvement of product competitiveness.

[0003] To address these issues, the industry has gradually shifted towards functional integration design, attempting to integrate multiple functional components onto a single decorative piece to reduce the number of feature surfaces and achieve a simplified yet sophisticated aesthetic. However, while integrated design brings benefits to appearance, it also introduces new technical challenges. First, ensuring precise assembly between the integrated component and surrounding components (such as the upper trim panel and door panel itself), as well as between the various functional modules it supports, to avoid uneven gaps and excessive surface differences that affect aesthetics and quality, presents a significant challenge. Second, integrated decorative pieces need to simultaneously support and install multiple functional components, significantly increasing the static and dynamic loads they bear. This places higher demands on the overall structural strength and deformation resistance of the components. Insufficient strength can lead to deformation and abnormal noises during long-term use, and may even directly affect the operational reliability and feel of critical safety features such as inward-opening handles. Finally, the integration of multiple components demands higher assembly precision; simplifying assembly and reducing installation costs are also pressing issues that need to be addressed. Utility Model Content

[0004] The purpose of this application is to provide an integrated decorative panel assembly and vehicle, which aims to solve the problem that existing integrated structures are unable to achieve a good balance between achieving a simple shape, precise assembly and ensuring structural strength.

[0005] In a first aspect, embodiments of this application provide an integrated decorative panel assembly, comprising: The upper trim panel includes a trim panel body with an accommodating hole, and a mounting piece disposed in the accommodating hole and connected to the trim panel body; A decorative element is disposed within the receiving hole, and the outer peripheral surface of the decorative element is adapted to the receiving hole. The decorative element has a mounting portion and a positioning portion, and also has a speaker mounting area and a handle mounting area. The mounting portion abuts against the mounting plate in the inward and outward directions and is connected to it. The mounting base is located on opposite sides of the upper trim panel along the inner and outer directions, and has a speaker assembly area and a handle assembly area. The speaker assembly area corresponds to the speaker mounting area, and the handle assembly area corresponds to the handle mounting area. The positioning part is inserted and positioned into the mounting base. The decorative piece and the upper trim panel are respectively connected to the mounting base.

[0006] The beneficial effects of the integrated decorative panel assembly provided in this application are as follows: Compared with the prior art, the decorative component is integrated into the receiving hole of the upper trim panel, its outer peripheral surface is adapted to the receiving hole, and it is connected to the mounting plate of the upper trim panel in the inward and outward directions through the mounting part. This achieves precise positioning and stable connection between the decorative component and the upper trim panel, which helps to eliminate the problems of uneven gaps and excessive surface differences that are easily caused by traditional multi-part assembly, and improves the overall integrity and refinement of the interior appearance. At the same time, the decorative component itself integrates speaker mounting area and handle mounting area, which, together with the corresponding speaker assembly area and handle assembly area on the mounting base, allows multiple functional modules to be precisely aligned and installed within a unified structure. This not only simplifies the assembly process and reduces mold development and manufacturing costs, but also enhances the overall load-bearing capacity and deformation resistance of each functional area under dynamic and static loads. Furthermore, the insertion and positioning between the positioning part of the decorative part and the mounting base not only allows for quick positioning of the mounting base, but also further enhances the overall rigidity and installation stability of the structure, effectively preventing deformation and abnormal noise that may occur during long-term use. Thus, while achieving a simple and unified interior design, it comprehensively improves the product's assembly quality, structural strength, and durability.

[0007] In conjunction with the first aspect, in one possible implementation, the decorative element further has a pre-installation part, the upper decorative panel has a pre-installation area corresponding to the pre-installation part, and the pre-installation part and the pre-installation area are detachably connected to realize the pre-installation of the decorative element.

[0008] In the aforementioned technical solution, the decorative component can be precisely and stably pre-positioned within the receiving hole of the upper trim panel before final assembly and fixation with the mounting base. This pre-installation structure prevents the decorative component from shifting or falling off during subsequent handling and final assembly, ensuring that its relative position to the upper trim panel always meets design requirements. This lays a reliable foundation for achieving uniform gaps and a smooth surface finish. Simultaneously, the pre-installation structure simplifies the overall assembly process, breaking down complex alignment operations into two more controllable steps: pre-installation and final assembly. This significantly reduces operational difficulty and time costs on the main assembly line, improving production efficiency and the consistency of assembly quality.

[0009] In conjunction with the first aspect, in one possible implementation, the decorative element further includes multiple assembly parts located in the central region of the decorative element. The mounting base has assembly holes adapted to the assembly parts, and the assembly parts are inserted into the assembly holes to achieve the connection between the decorative element and the mounting base.

[0010] In the above technical solution, multiple assembly parts are set in the central area of ​​the decorative component, and corresponding assembly holes are opened on the mounting base. The plug-in connection between the assembly parts and the assembly holes achieves a direct and stable connection between the decorative component and the mounting base in key stress areas. This solution can more effectively transfer and distribute the load borne by the decorative component, especially the concentrated dynamic force generated when operating the handle, to the mounting base, thereby improving the structural stability and deformation resistance of the integrated assembly under long-term use. It effectively avoids problems such as abnormal noise, loosening, or a flimsy feel that may be caused by insufficient local stiffness. At the same time, this plug-in structure provides clear and rapid positioning guidance for the final assembly of the decorative component and the mounting base, simplifying the assembly alignment process. In conjunction with the first aspect, in one possible implementation, the mounting base has a reinforcing plate disposed within the mounting hole, the mounting portion has a reinforcing hole adapted to the reinforcing plate, and the reinforcing plate is inserted into the reinforcing hole.

[0011] In the above technical solution, a double-plug structure is formed by setting a reinforcing plate in the mounting hole of the mounting base and correspondingly opening a reinforcing hole on the mounting part of the decorative part. When the handle is frequently operated or the assembly is subjected to vibration load, the tight fit between the reinforcing plate and the reinforcing hole can effectively suppress the micro-deformation and displacement at the connection point, thereby dispersing the concentrated stress more evenly, greatly improving the structural durability of the assembly under long-term dynamic load, and effectively eliminating the risk of abnormal noise caused by plastic deformation or wear at the connection point.

[0012] In conjunction with the first aspect, in one possible implementation, the positioning part is provided in multiple ways, and the multiple positioning parts are distributed on opposite sides of the handle mounting area. The mounting base has positioning holes that correspond one-to-one with the positioning parts. One of the positioning parts is transitionally or interference-fitted with the corresponding positioning hole, and the other positioning parts are clearance-fitted with the corresponding positioning holes. The aforementioned technical solution effectively restricts the degree of freedom of the decorative component around the handle installation area through a main positioning point, ensuring the assembly rigidity and positional accuracy of the core functional area, and directly improving the stability and feel of the inward-opening handle during operation. Furthermore, multiple positioning points provide necessary tolerance compensation, absorbing unavoidable dimensional deviations during parts manufacturing and assembly, preventing assembly stress or difficulties caused by tolerance accumulation. This positioning scheme balances precise constraints and tolerance absorption, significantly improving production yield and assembly efficiency while ensuring the overall structural strength and connection reliability of the assembly.

[0013] In conjunction with the first aspect, in one possible implementation, both the mounting plate and the mounting base have mounting holes corresponding to the mounting portion, and the mounting portion is inserted into the mounting holes.

[0014] In the above technical solution, during assembly, the mounting part of the decorative component can pass through the corresponding mounting holes of the mounting plate and the mounting base in one go, eliminating the need for separate alignment and connection of the decorative component with the upper trim panel and the decorative component with the mounting base. This significantly simplifies the steps of multi-component collaborative assembly, reduces operational complexity, and improves overall assembly efficiency. Simultaneously, the mounting part inserts and connects the mounting plate and the mounting base, tightly linking the upper trim panel, decorative component, and mounting base into a single unit, effectively avoiding the relative loosening problems that may occur with traditional separate connections.

[0015] In conjunction with the first aspect, in one possible implementation, the mounting portion has a locking hole, and the integrated decorative panel assembly further includes a locking element inserted into the locking hole.

[0016] In the above technical solution, after the mounting part is inserted through the mounting holes of the mounting plate and the mounting seat during assembly, the locking part is inserted into the locking hole to form a mechanical locking structure, which can effectively limit the axial movement of the mounting part in the mounting hole, avoid loosening of the connection due to vibration and bumps during vehicle operation, and ensure that the three parts always maintain a tight connection.

[0017] In conjunction with the first aspect, in one possible implementation, the mounting pieces are provided with multiple mounting plates along the inner periphery of the receiving hole, and the mounting parts correspond one-to-one with the mounting pieces. One of the mounting parts is transitionally or interference-fitted with the corresponding mounting hole to form a main positioning structure, while the other mounting parts are clearance-fitted with the corresponding mounting holes to form auxiliary positioning structures.

[0018] In the aforementioned technical solution, the connection between the upper trim panel and the decorative parts, as well as the connection between the decorative parts and the mounting base, are achieved simultaneously through the same set of mounting parts, greatly simplifying the assembly relationship of the assembly. This not only reduces the number of fasteners and assembly steps, lowering manufacturing costs and the probability of errors, but more importantly, this through-type connection tightly integrates the three-layer structure into a rigid whole, significantly enhancing the tensile strength and overall stability of the assembly in both internal and external directions. It effectively prevents separation, abnormal noise, or loosening between the various components due to long-term vibration or stress, ensuring the long-term reliability of the interior functions and high-quality visual integrity.

[0019] In conjunction with the first aspect, in one possible implementation, the upper trim panel further includes a fixing part disposed on the trim panel body and located around the receiving hole, the mounting base having a fixing hole adapted to the fixing part, the fixing part being inserted into the fixing hole to realize the connection between the mounting base and the upper trim panel.

[0020] In the above technical solution, a fixing part is provided around the receiving hole of the upper trim panel, and a corresponding fixing hole is opened on the mounting base. By using the plug-in cooperation between the fixing part and the fixing hole, the upper trim panel and the mounting base are directly connected around the periphery of the decorative part area. This structure effectively distributes the load borne by the decorative part, avoiding the need for all stress to be transmitted through the decorative part, thereby reducing the risk of deformation of the decorative part due to excessive stress.

[0021] Secondly, embodiments of this application also provide a vehicle including the integrated decorative panel assembly described above.

[0022] The beneficial effect of the vehicle provided in this application is that, compared with the prior art, it adopts the above-mentioned integrated decorative panel assembly, which has similar technical effects to the above-mentioned integrated decorative panel assembly, and will not be described in detail here.

[0031] Please refer to the following: Figures 1 to 7 The integrated trim panel assembly and vehicle provided in this application will now be described. The integrated trim panel assembly includes an upper trim panel 1, a trim piece 2, and a mounting base 3. The upper trim panel 1 includes a trim panel body 101 with an accommodating hole 105, and a mounting piece 102 disposed within the accommodating hole 105 and connected to the trim panel body 101. The trim piece 2 is disposed within the accommodating hole 105, and its outer peripheral surface is adapted to the accommodating hole 105. The trim piece 2 has a mounting portion 204 and a positioning portion 205, and also has a speaker mounting area 202 and a handle mounting area 201. Part 204 abuts against the mounting plate 102 in the inward and outward directions and is connected to each other; the mounting base 3 and the decorative part 2 are respectively located on opposite sides of the upper trim panel 1 in the inward and outward directions. The mounting base 3 has a speaker assembly area 302 and a handle assembly area 301. The speaker assembly area 302 corresponds to the speaker mounting area 202, and the handle assembly area 301 corresponds to the handle mounting area 201. The positioning part 205 is inserted into the mounting base 3 for positioning. The decorative part 2 and the upper trim panel 1 are respectively connected to the mounting base 3.

[0032] Compared with the prior art, the integrated decorative panel assembly provided in this application integrates components such as speakers and handles into the speaker mounting area 202 and handle mounting area 201 of the decorative part 2, replacing the traditional method of dispersing multiple independent components. This reduces the number of feature surfaces of the interior decorative part 2, avoids the problem of fragmented interior visual presentation, and makes it easier to form a unified interior styling style.

[0033] During assembly, the decorative part 2 is directly embedded into the matching receiving hole 105 and abuts against the mounting piece 102 of the upper trim panel 1, achieving multiple positioning of the decorative part 2 in the internal and external directions, circumferential direction, and radial direction. The mounting base 3 is inserted and positioned with the positioning part 205 of the decorative part 2, realizing quick alignment and positioning of the mounting base 3 during assembly, simplifying the installation steps, improving installation accuracy, and connecting the mounting base 3 to the decorative part 2 and the upper trim panel 1 respectively, thereby improving the connection strength and reliability. This application effectively avoids problems such as uneven gaps and excessive surface differences that affect aesthetics and quality by limiting the decorative part 2 in multiple directions and fixing the mounting base 3 at multiple points. The mounting base 3 and the decorative part 2 are respectively set on opposite sides of the upper decorative panel 1, and the three are connected to form a stable overall structure. Compared with a single decorative part 2 bearing a functional component, this structure can more evenly distribute the static and dynamic loads borne by the decorative part 2, significantly improving the overall structural strength and deformation resistance of the integrated decorative panel assembly. It can effectively prevent deformation and abnormal noise during long-term use, simplify the assembly process, and reduce installation costs.

[0034] Optionally, the mounting base 3 can be bonded, welded, snapped, screwed, or riveted to the decorative part 2.

[0035] It should be noted that the upper trim panel 1 is mainly used to provide mounting positions for the trim piece 2 and the mounting base 3. Its name is not limited to a specific component and can also be other components in the vehicle that have mounting or fixing functions.

[0036] Please see Figures 3 to 6 In some embodiments, the decorative element 2 also has a pre-installation part 203, and the upper decorative panel 1 has a pre-installation area 103 corresponding to the pre-installation part 203. The pre-installation part 203 and the pre-installation area 103 are detachably connected to realize the pre-installation of the decorative element 2.

[0037] First, the decorative part 2 is detachably connected to the pre-installation area 103 of the upper trim panel 1 via the pre-installation part 203, completing the pre-installation positioning of the decorative part 2 within the receiving hole 105 of the upper trim panel 1. This pre-installation method pre-fixes the relative position of the decorative part 2 and the upper trim panel 1, preventing issues such as offset or wobbling of the decorative part 2 during subsequent assembly processes such as mounting base 3 and connecting mounting part 204. This significantly reduces the operational difficulty of multi-component collaborative assembly and improves assembly efficiency. Simultaneously, the relatively stable position of the decorative part 2 in the pre-installed state allows for more precise alignment with the positioning structure of the mounting base 3 and the assembly areas of the speaker and handle, reducing assembly errors caused by component misalignment and further ensuring accurate assembly results.

[0038] Optionally, the pre-installation unit 203 can be snapped or attached to the pre-installation area 103.

[0039] Optionally, the mounting base 3 is provided with a clearance hole 303 corresponding to the pre-installed part 203 to avoid interference between the decorative part 2 and the mounting base 3.

[0040] Please see Figures 2 to 6 In some embodiments, the decorative part 2 also has a plurality of mounting parts 206, which are located in the central area of ​​the decorative part 2. The mounting base 3 has mounting holes 304 adapted to the mounting parts 206, and the mounting parts 206 are inserted into the mounting holes 304 to realize the connection between the decorative part 2 and the mounting base 3.

[0041] When the decorative part 2 mates with the mounting base 3, the insertion and engagement of multiple assembly parts 206 and assembly holes 304 can quickly form multi-point positioning. Combined with the previous positioning part 205 structure, it improves the alignment accuracy between the decorative part 2 and the mounting base 3, avoids the offset problem that may occur with single positioning, and ensures that subsequent functional components such as speakers and handles can be accurately assembled into the corresponding areas.

[0042] The assembly section 206 is located in the central area of ​​the decorative component 2. This area is where the load is relatively concentrated after integrating multiple functional components. The plug-in connection between multiple assembly sections 206 and the assembly holes 304 can evenly transfer the load in the central area to the mounting base 3. Together with other connection structures between the decorative component 2, the upper decorative panel 1, and the mounting base 3, a more balanced force distribution is formed, effectively enhancing the stability of the connection between the decorative component 2 and the mounting base 3, and reducing problems such as structural deformation and loosening of connections caused by excessive central load during long-term use. At the same time, the plug-in connection method is simple to operate and can be assembled without complicated tools. Combined with the pre-assembled structure, it can further simplify the overall assembly process, reduce labor and time costs, improve assembly efficiency in mass production, and provide stronger support for the large-scale application of integrated decorative panel assemblies.

[0043] Optionally, multiple assembly parts 206 are located around the handle mounting area 201.

[0044] Optionally, the assembly part 206 can be snapped, screwed, or riveted to the assembly hole 304, or it can be other plug-in connection structures.

[0045] Please see Figure 4 and Figure 7 In some embodiments, the mounting base 3 has a reinforcing piece 3041 disposed in the mounting hole 304, and the mounting part 206 has a reinforcing hole 2061 adapted to the reinforcing piece 3041, and the reinforcing piece 3041 is inserted into the reinforcing hole 2061.

[0046] The insertion and engagement of the reinforcing plate 3041 and the reinforcing hole 2061 form a double insertion structure in addition to the basic connection between the assembly part 206 and the assembly hole 304. This significantly increases the contact area and engagement depth between the decorative part 2 and the mounting base 3, effectively resisting the relative displacement caused by vibration and external force during use, and preventing loosening of the connection. In particular, it can more stably transmit the loads such as the handle operation force and speaker working vibration borne by the central area of ​​the decorative part 2 to the mounting base 3, reducing local stress concentration.

[0047] After the assembly part 206 and the assembly hole 304 are initially connected, the reinforcement plate 3041 and the reinforcement hole 2061 are precisely matched to further correct any possible minor assembly deviations, ensuring the relative positional accuracy of the decorative part 2 and the mounting base 3, and providing a more reliable foundation for the precise assembly of subsequent functional components.

[0048] Optionally, the reinforcing plate 3041 includes a first reinforcing part and a second reinforcing part arranged at an angle, the first reinforcing part being connected to the mounting base 3, and the second reinforcing part being inserted into the reinforcing hole 2061.

[0049] Please see Figures 2 to 3 ,and Figures 6 to 7 In some embodiments, multiple positioning parts 205 are provided, and the multiple positioning parts 205 are distributed on opposite sides of the handle mounting area 201. The mounting base 3 has positioning holes 305 that correspond one-to-one with the positioning parts 205. One positioning part 205 is transitionally or interference-fitted with the corresponding positioning hole 305, while the other positioning parts 205 are clearance-fitted with the corresponding positioning hole 305. During assembly, each positioning part 205 can be aligned with the corresponding positioning hole 305. The positioning parts 205 with transition or interference fit can serve as reference positioning points to quickly determine the core relative position of the decorative part 2 and the mounting base 3 in the handle mounting area 201, ensuring the reference accuracy of the subsequent assembly of the handle. The remaining positioning parts 205 with clearance fit can flexibly compensate for minor dimensional errors or component deformation that may occur during the assembly process, avoiding assembly jamming caused by tight fit of all positioning parts 205 and component damage caused by forced assembly, greatly reducing the difficulty of assembly operation and improving assembly efficiency.

[0050] The handle mounting area 201 is a core area frequently used by users and subject to concentrated forces. Multiple positioning parts 205 are distributed on both sides, providing stable support for the decorative part 2 from both sides. Combined with the tight fixing of the reference positioning parts 205, it effectively resists the forces generated during handle operation, reduces the relative displacement between the decorative part 2 and the mounting base 3, and prevents loosening and abnormal noise after long-term use, ensuring the handle's operating feel and structural stability. At the same time, this differentiated design eliminates the need for additional positioning components or complex processing techniques, ensuring positioning accuracy and structural stability without increasing production and assembly costs.

[0051] Optionally, multiple positioning parts 205 are distributed on opposite sides of the handle mounting area 201 in a front-back or left-right direction.

[0052] Please see Figure 2 and Figure 7 In some embodiments, both the mounting plate 102 and the mounting base 3 are provided with mounting holes 307 corresponding to the mounting part 204, and the mounting part 204 is inserted into the mounting holes 307.

[0053] During assembly, the mounting portion 204 of the decorative component 2 can pass through the mounting holes 307 corresponding to the mounting plate 102 and the mounting base 3 in one go, eliminating the need for separate alignment and connection of the decorative component 2 with the upper trim panel 1 and the decorative component 2 with the mounting base 3. This greatly simplifies the steps of multi-component collaborative assembly, reduces operational complexity, and improves overall assembly efficiency. At the same time, the mounting portion 204 is inserted into and connects the mounting plate 102 and the mounting base 3, which can tightly connect the upper trim panel 1, the decorative component 2, and the mounting base 3 into a whole. This effectively avoids the problem of relative looseness of the components that may occur with traditional separate connections. In particular, for dynamic loads such as speaker vibration and inner handle operation force borne by the decorative component 2, this connection structure can evenly transfer them to the mounting base 3 and the upper trim panel 1, reducing local stress concentration and improving the deformation resistance of the overall structure.

[0054] In addition, the matching design of the mounting hole 307 and the mounting part 204 ensures the centering of the decorative part 2 within the receiving hole 105 of the upper trim panel 1, as well as the precise alignment of the mounting base 3 and the functional area of ​​the decorative part 2. This avoids problems such as uneven gaps and excessive surface differences caused by the connection deviation of multiple parts, further ensuring the refinement of the interior appearance and the assembly accuracy of the functional components.

[0055] Optionally, the mounting part 204 is a screw-on or snap-on component, used to connect the mounting base 3, the upper trim panel 1, and the decorative component 2.

[0056] Please see Figure 2 In some embodiments, the mounting part 204 has a locking hole 2041, and the integrated decorative panel assembly also includes a locking member 4 inserted into the locking hole 2041.

[0057] During assembly, after the mounting part 204 is inserted through the mounting holes 307 of the mounting plate 102 and the mounting base 3, the locking member 4 is inserted into the locking hole 2041 to form a mechanical locking structure. This effectively restricts the axial movement of the mounting part 204 in the mounting hole 307, preventing the connection from loosening due to vibration and bumps during vehicle operation, and ensuring that the three parts always maintain a tight connection.

[0058] The plug-in design of locking component 4 makes it easy to operate, and locking or disassembling can be completed without complicated tools. It improves the connection strength without increasing the assembly complexity, and is suitable for the high-efficiency operation requirements in mass production.

[0059] Optionally, the locking element 4 can be a threaded element or a riveted element.

[0060] Please see Figure 3 and Figure 5 In some embodiments, the mounting piece 102 is provided with a plurality of mounting portions 204 along the inner periphery of the receiving hole 105, and the mounting portions 204 correspond one-to-one with the mounting piece 102. One of the mounting portions 204 is transitionally or interference-fitted with the corresponding mounting hole 307 to form a main positioning structure, and the other mounting portions 204 are clearance-fitted with the corresponding mounting holes 307 to form an auxiliary positioning structure.

[0061] During assembly, the transition or interference fit of the main positioning structure can quickly establish a precise assembly reference for the decorative part 2 within the receiving hole 105 of the upper trim panel 1, avoiding offset; while the clearance fit of the auxiliary positioning structure can flexibly compensate for minor dimensional errors that may exist in the processing and assembly of the decorative part 2 or the upper trim panel 1, preventing assembly jamming caused by all mounting parts 204 being tight fits, or even deformation and damage to the mounting piece 102 or mounting part 204 caused by forced assembly, reducing the difficulty of assembly operations and improving assembly efficiency.

[0062] Multiple mounting pieces 102 are evenly distributed along the inner circumference of the receiving hole 105, forming multi-point support in conjunction with the main and auxiliary positioning structures. This allows the loads borne by the decorative piece 2 (such as handle operating force and speaker vibration) to be evenly transferred to the upper decorative panel 1, avoiding structural deformation caused by local stress concentration. At the same time, the tight fit of the main positioning structure can limit the lateral displacement of the decorative piece 2, while the auxiliary positioning structure can help fix the position of the decorative piece 2. The two work together to ensure that the decorative piece 2 does not loosen or make abnormal noises during long-term use, thus guaranteeing functional reliability.

[0063] Optionally, multiple mounting portions 204 are arranged in a ring on the decorative component 2. This ring-shaped arrangement of mounting portions 204 disperses the load borne by the decorative component 2 to the upper trim panel 1 and the mounting base 3, avoiding localized stress concentration caused by traditional asymmetrical distribution. This effectively reduces the risk of deformation and cracking of the decorative component 2 after long-term use, significantly improving the fatigue resistance of the overall structure. Furthermore, it allows for more precise control of the coaxiality between the decorative component 2 and the receiving hole 105 in the upper trim panel 1, preventing eccentricity and ensuring that its outer circumferential surface always fits snugly against the receiving hole 105, further eliminating problems such as uneven gaps and excessive surface differences.

[0064] Please see Figures 2 to 3 ,and Figure 5 , Figure 7In some embodiments, the upper trim panel 1 further includes a fixing part 104 disposed on the trim panel body 101 and located around the receiving hole 105. The mounting base 3 has a fixing hole 306 adapted to the fixing part 104. The fixing part 104 is inserted into the fixing hole 306 to realize the connection between the mounting base 3 and the upper trim panel 1.

[0065] The fixing part 104 is inserted into the fixing hole 306, which not only realizes the positioning of the mounting base 3 and the upper trim panel 1, and avoids the mounting base 3 from shifting during the assembly process; at the same time, it connects the upper trim panel 1 and the mounting base 3, which complements the connection structure of the mounting base 3 and the decorative part 2, and transfers the load borne by the mounting base 3 from the outside to the upper trim panel 1, avoiding the load from being concentrated on the single structure of the decorative part 2, and effectively enhancing the deformation resistance of the overall structure.

[0066] Based on the same inventive concept, this application also provides a vehicle. The vehicle includes the aforementioned integrated trim panel assembly.

[0067] The vehicle provided by this utility model adopts the above-mentioned integrated decorative panel assembly. By integrating components such as speakers and handles into the speaker mounting area 202 and handle mounting area 201 of the decorative part 2, it replaces the traditional method of dispersing multiple independent components, reduces the number of feature surfaces of the interior decorative part 2, avoids the problem of fragmented interior visual presentation, and makes it easier to form a unified interior styling style.

[0068] During assembly, the decorative part 2 is directly embedded into the matching receiving hole 105 and abuts against the mounting piece 102 of the upper trim panel 1, achieving multiple positioning of the decorative part 2 in the internal and external directions, circumferential direction, and radial direction. The mounting base 3 is inserted and positioned with the positioning part 205 of the decorative part 2, realizing quick alignment and positioning of the mounting base 3 during assembly, simplifying the installation steps, improving installation accuracy, and connecting the mounting base 3 to the decorative part 2 and the upper trim panel 1 respectively, thereby improving the connection strength and reliability. This application effectively avoids problems such as uneven gaps and excessive surface differences that affect aesthetics and quality by limiting the decorative part 2 in multiple directions and fixing the mounting base 3 at multiple points. The mounting base 3 and the decorative part 2 are respectively set on opposite sides of the upper decorative panel 1, and the three are connected to form a stable overall structure. Compared with a single decorative part 2 bearing a functional component, this structure can more evenly distribute the static and dynamic loads borne by the decorative part 2, significantly improving the overall structural strength and deformation resistance of the integrated decorative panel assembly. It can effectively prevent deformation and abnormal noise during long-term use, simplify the assembly process, and reduce installation costs.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
