Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a trim panel assembly, a vehicle body, and a vehicle. Background Technology

[0002] With technological advancements, users' demands for vehicle experience quality have risen rapidly. To improve sound quality and increase the sound field, dozens of speakers are installed inside the vehicle, with corresponding decorative covers on the interior panels to ensure that the sound emitted by the speakers can be transmitted to the cabin. However, in these technologies, the assembly precision between the decorative covers and the interior panels is relatively low, resulting in significant surface differences between the surfaces of the decorative covers and the interior panels. Utility Model Content

[0008] In some possible implementations of the first aspect, the decorative panel includes a decorative panel body, a positioning post, and at least one set of first stiffeners. The positioning post is fixed to the decorative panel body. A set of first stiffeners connects the outer peripheral surface of a positioning post to the decorative panel body, and a portion of the surface of the first stiffeners forms at least a portion of the positioning area.

[0009] In some possible implementations of the first aspect, the decorative panel further includes at least one set of second stiffeners. At least a portion of the second stiffeners are located on the side of the first stiffener away from the decorative panel body, along the normal of the positioning area; the set of second stiffeners is connected to the outer peripheral surface of a positioning post and is fitted between the outer peripheral surface of the positioning post and the inner peripheral surface of the limiting hole.

[0010] In some possible implementations of the first aspect, the decorative panel is a one-piece molded structure.

[0011] In some possible implementations of the first aspect, the positioning post is welded to the bracket.

[0012] In some possible implementations of the first aspect, the decorative panel is a one-piece molded structure; the positioning column is welded to the bracket.

[0013] In some possible implementations of the first aspect, the bracket includes a bracket body and a connecting ear. The bracket body has a second mounting hole, which is opposite to and extends through the first mounting hole; a decorative cover is connected to the bracket body and covers the second mounting hole. The connecting ear is connected to the bracket body and extends to the outer periphery of the bracket body, and a portion of the surface of the connecting ear forms a mating area.

[0014] In some possible implementations of the first aspect, the limiting hole is formed in the connecting ear.

[0015] In some possible implementations of the first aspect, the bracket has a plurality of connecting holes arranged circumferentially spaced along the first mounting hole. The decorative cover includes a cover body and a plurality of connecting pieces. The cover body is fitted into the first mounting hole and has a sound outlet. The connecting pieces are connected to the cover body and extend toward the side facing the second surface, with a portion of one connecting piece passing through a connecting hole, and the cover is fixed to the bracket by the connecting pieces.

[0016] In some possible implementations of the first aspect, the decorative cover has a fourth surface that faces the same direction as the first surface, and the edge of the fourth surface is flush with the edge of the first mounting hole located on the first surface.

[0017] In some possible implementations of the first aspect, the mating clearance between at least a portion of the decorative cover and the first mounting hole is less than or equal to 0.5 mm.

[0021] The decorative panel assembly, body, and vehicle provided in this application have the following beneficial effects:

[0022] The decorative panel assembly provided in this application, by having a positioning area on the second surface and a mating area on the third surface of the bracket, with at least a portion of the mating area abutting the positioning area, can restrict the movement of the bracket relative to the decorative panel along the normal direction of the positioning area and its rotation about a direction perpendicular to the normal direction of the positioning area; by having a plurality of positioning posts on the second surface, with one positioning post fitted into a limiting hole, can restrict the movement of the bracket relative to the decorative panel along a direction perpendicular to the normal direction of the positioning area and its rotation about the normal direction of the positioning area.

[0023] Therefore, when assembling the bracket, decorative cover, and decorative panel, the six degrees of freedom of the bracket can be restricted to ensure the accuracy of the relative position of the bracket and the decorative panel, thereby ensuring the accuracy of the relative position of the decorative cover and the decorative panel, and thus ensuring the assembly precision of the decorative cover and the decorative panel. In addition, during transportation and vehicle operation, the bracket and the decorative cover will not wobble relative to the decorative panel, which helps to improve the overall reliability and appearance of the decorative panel assembly, thereby improving the user experience.

[0036] In the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0037] In the embodiments of this application, it should be understood that the directional terms mentioned, such as "up", "down", "left", "right", "inner", "outer", etc., are only for reference to the direction of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to 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 the embodiments of this application.

[0038] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0039] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0040] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0041] In the embodiments of this application, it should be noted that the descriptions of "vertical" and "parallel" respectively indicate approximately vertical and approximately parallel within a certain error range. This error range can be a range with a deviation angle of less than or equal to 5°, 8° or 10° relative to absolute verticality and absolute parallelism, respectively, and is not specifically limited here.

[0042] With technological advancements, user demands for vehicle experience quality have risen rapidly. To improve sound quality and expand the sound field, dozens of speakers (such as tweeters) are installed inside the vehicle, with corresponding decorative covers on the trim panels. This allows the sound emitted by the speakers to be transmitted into the cabin through the sound outlets on the covers, while also enhancing the vehicle's aesthetic appeal. Please refer to [link / reference]. Figure 1 , Figure 1This is a cross-sectional structural diagram of the trim panel and trim cover assembly structure in the related technology. The surface of the trim cover 123 facing the interior of the driver's compartment 10a has a surface difference with the surface of the trim panel 121 facing the interior of the driver's compartment 10a. For example, the outer surface of the trim cover 123, especially near its peripheral edge, protrudes beyond the outer surface of the trim panel 121, or is lower than the outer surface of the trim panel 121, or partly higher than the outer surface of the trim panel 121 and partly lower, or the gap between the outer peripheral surface of the trim cover 123 and the inner peripheral surface of the mounting hole of the trim panel 121 is too large, etc., failing to meet the Dimension Technical Specifications (DTS) standards. Users will be very sensitive and uncomfortable to the surface difference between the outer surface of the trim cover 123 and the outer surface of the trim panel 121, which will raise concerns about the overall assembly quality of the vehicle.

[0043] To resolve the above issues, please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a vehicle 100 provided in some embodiments of this application. This application provides a vehicle 100, which includes a body 10 and a plurality of doors 20. A portion of the body 10 encloses a driver's cabin 10a. The doors 20 are rotatably connected to the body 10. When the doors 20 are open, users can enter and exit the driver's cabin 10a. When the doors 20 are closed, they protect the driver's cabin 10a to ensure the personal and property safety of the user. The body 10 includes a body frame 11, which includes a first connecting pillar (also called an A-pillar) 111, a second connecting pillar (also called a B-pillar) 112, and a third connecting pillar (also called a C-pillar) 113 spaced apart. In some other embodiments, the body frame 11 may not include the second connecting pillar 112 and / or the third connecting pillar 113; this application does not limit this.

[0044] Please refer to the following: Figure 2 and see Figure 3 , Figure 3 for Figure 2 The diagram shows the structure of the trim panel assembly 12 of the vehicle 100. The vehicle body 10 also includes the trim panel assembly 12, which is connected to the vehicle body 11. Specifically, the trim panel assembly 12 can be connected to the first connecting pillar 111 by means of snap-fit, adhesive, bolt connection, etc. Part of the surface of the trim panel assembly 12 forms part of the inner wall surface of the driver's cabin 10a, that is, the trim panel assembly 12 is an A-pillar interior trim panel assembly. In some other embodiments, the trim panel assembly 12 can also be connected to the second connecting pillar 112, or to the third connecting pillar 113, or to the crossbeam structure of the vehicle body 11; this application does not limit this.

[0045] Please refer to the following: Figures 3-5 , Figure 4 for Figure 3 The diagram shows a partial structural representation of the decorative panel assembly 12 as viewed from another angle. Figure 5 for Figure 3 The diagram shows a partial structural schematic of the decorative panel 121 of the decorative panel assembly 12. The decorative panel assembly 12 includes a decorative panel 121, a bracket 122, and a decorative cover 123. The decorative panel assembly 12 can be connected to the A-pillar via the decorative panel 121 or via the bracket 122. The decorative panel 121 is generally elongated, but it can also be an arc-shaped plate or a flat plate. In some other embodiments, the decorative panel 121 can also have other shapes. The decorative panel 121 has a first surface 121a and a second surface 121b arranged along the thickness direction, and a first mounting hole 121c penetrating the first surface 121a and the second surface 121b, wherein the first surface 121a forms part of the inner wall surface of the cockpit 10a. Based on this, the second surface 121b has a positioning area 121b1 and a plurality of spaced and parallel positioning posts 1211, which intersect the plane containing the positioning area 121b1.

[0046] For ease of description below, an XYZ coordinate system is established for the decorative panel assembly 12. The normal direction of the positioning region 121b1 is defined as the Y-axis direction, and two mutually perpendicular directions, both perpendicular to the Y-axis direction, are the X-axis direction and the Z-axis direction. Specifically, the X-axis direction can be approximately the same as the length direction of the decorative panel 121. In some other embodiments, the X-axis direction and the Z-axis direction can also be other directions, which are not limited in this application.

[0047] Figures 3-5 In the illustrated embodiment, there are four positioning posts 1211. Some of the positioning posts 1211 have a circular cross-section, while others have a rectangular cross-section. The positioning posts 1211 are perpendicular to the plane containing the positioning area 121b1. In other embodiments, the number of positioning posts 1211 may be two, three, or five, etc. All positioning posts 1211 may have a circular, rectangular, or other shaped cross-section. The positioning posts 1211 may also not be perpendicular to the plane containing the positioning area 121b1; for example, the angle between the positioning posts 1211 and the plane containing the positioning area 121b1 may be 85°, 80°, 75°, etc.

[0048] Based on this, please refer to the following: Figure 3 , Figure 4 and Figure 6 , Figure 6This is a schematic diagram of the assembly structure of bracket 122 and decorative cover 123. Bracket 122 is located on the side opposite to the first surface 121a and is fixed to the decorative panel 121. One or more speakers (not shown) of the vehicle 100 are located between the decorative panel 121 and the A-pillar. The speakers can be mounted and fixed to bracket 122 or to the A-pillar. Bracket 122 has a third surface 122a, which faces the same direction as the first surface 121a. The third surface 122a has a mating area 122a1 and a plurality of limiting holes 122a2. At least a portion of the mating area 122a1 is fitted with a positioning area 121b1. A positioning post 1211 is fitted and accommodated within a limiting hole 122a2. Specifically, the positioning post 1211 can be clearance-fitted with the limiting hole 122a2 to facilitate the insertion of the positioning post 1211 into the limiting hole 122a2. In some other embodiments, the positioning post 1211 may also have a transition fit or an interference fit with the limiting hole 122a2.

[0049] Based on the above, the decorative cover 123 is connected to the bracket 122, and at least a portion of the decorative cover 123 is fitted into the first mounting hole 121c. The decorative cover 123 has a sound outlet hole 123a so that the sound generated by the speaker can be transmitted to the cockpit 10a through the sound outlet hole 123a to improve the user experience.

[0050] In this way, by having the decorative panel 121 have a first mounting hole 121c, the bracket 122 is located on the side opposite to the second surface 121b of the decorative panel 121 and fixed to the decorative panel 121, the decorative cover 123 is connected to the bracket 122, at least a part of the decorative cover 123 is fitted into the first mounting hole 121c, and the decorative cover 123 has a sound outlet hole 123a, so that the sound generated by the speaker can be transmitted to the cockpit 10a through the sound outlet hole 123a of the decorative cover 123, thereby improving the user experience.

[0051] Based on this, by making the second surface 121b have a positioning area 121b1 and the third surface 122a of the bracket 122 have a mating area 122a1, at least a portion of the mating area 122a1 is in contact with the positioning area 121b1, the movement of the bracket 122 relative to the decorative panel 121 along the Y-axis direction and the rotation around the X-axis direction and the Z-axis direction can be restricted; by making the second surface 121b have a plurality of positioning posts 1211, and one positioning post 1211 is fitted and accommodated in a limiting hole 122a2, the movement of the bracket 122 relative to the decorative panel 121 along the X-axis direction and the Z-axis direction and the rotation around the Y-axis direction can be restricted.

[0052] Therefore, when assembling the bracket 122, decorative cover 123, and decorative panel 121, the six degrees of freedom of the bracket 122 can be restricted to ensure the accuracy of the relative position between the bracket 122 and the decorative panel 121, thereby ensuring the accuracy of the relative position between the decorative cover 123 and the decorative panel 121, and thus ensuring the assembly precision of the decorative cover 123 and the decorative panel 121. In addition, during process transportation and vehicle 100 driving, the bracket 122 and the decorative cover 123 will not wobble relative to the decorative panel 121, which helps to improve the overall appearance of the decorative panel assembly 12 and improve the user experience.

[0053] Please continue reading. Figure 3 The decorative cover 123 includes a fourth surface 123b, which faces the same direction as the first surface 121a. The edge of the fourth surface 123b is flush with the edge of the first mounting hole 121c located on the first surface 121a. It should be noted that "the edge of the fourth surface 123b is flush with the edge of the first mounting hole 121c" means that, if any point on the fourth surface 123b is designated as the first position point, and the point on the edge of the first mounting hole 121c closest to the first position point is designated as the second position point, the height difference between the first position point and the second position point along the normal direction at the second position point on the first surface 121a is approximately 0. That is, the fourth surface 123b and the first surface 121a are located within the same continuous curved surface.

[0054] In this way, the surface of the inner wall of the cabin 10a formed by the decorative panel assembly 12 forms a continuous curved surface, i.e., the surface difference is 0. The appearance of the decorative panel assembly 12 is better. Especially when the materials of the decorative cover 123 and the decorative panel 121 are different, it can prevent the user from having a poor experience of using the vehicle due to the surface difference between the decorative panel 121 and the decorative cover 123.

[0055] Please see Figures 4-6 There are multiple positioning areas 121b1, which are distributed circumferentially around the first mounting hole 121c. Correspondingly, there are also multiple mating areas 122a1 on the bracket 122, each corresponding to and fitting one-to-one with the positioning areas 121b1. In this way, the positioning areas 121b1 and the multiple mating areas 122a1 work together to form a multi-point support and positioning structure distributed around the first mounting hole 121c between the decorative panel 121 and the bracket 122. This maximizes the total positioning area formed by the positioning areas 121b1, ensuring positioning accuracy. Furthermore, it saves space and facilitates the installation of other structures.

[0056] Figures 4-6In the illustrated embodiment, there are four positioning areas 121b1 and four mating areas 122a1, distributed approximately at equal angles along the circumference of the first mounting hole 121c, so that the decorative panel 121 and the bracket 122 are subjected to uniform force, ensuring the overall reliability of the decorative panel assembly 12. In other embodiments, the number of positioning areas 121b1 and the number of mating areas 122a1 may also be two, three, five, etc.

[0057] In some other embodiments, the number of positioning areas 121b1 may be one, extending continuously along the circumference of the first mounting hole 121c, i.e., the extension trajectory of the positioning area 121b1 is arc-shaped; the number of mating areas 122a1 may be multiple, and multiple mating areas 122a1 may fit with the positioning areas 121b1 to perform multi-point positioning of the bracket 122. In some other embodiments, the number of mating areas 122a1 may be one, and the number of positioning areas 121b1 may be multiple, with the mating areas 122a1 fitting with all the positioning areas 121b1 to perform multi-point positioning of the bracket 122. In some other embodiments, the number of both positioning areas 121b1 and mating areas 122a1 may be one, and both may extend continuously along the circumference of the first mounting hole 121c.

[0058] Please continue reading. Figures 4-6 The positioning areas 121b1 correspond one-to-one with the positioning posts 1211, with each positioning area 121b1 located around and connected to a positioning post 1211. This facilitates the design and fabrication of the positioning areas 121b1 and the positioning posts 1211, and also facilitates the assembly of the decorative panel 121 and the bracket 122, thereby improving the assembly accuracy of the decorative panel 121 and the bracket 122. In some other embodiments, the positioning areas 121b1 may also be spaced apart from the positioning posts 1211.

[0059] Please continue reading. Figures 4-6 In one possible implementation, the decorative panel 121 includes a decorative panel body 1212, the aforementioned positioning post 1211, and at least one set of first stiffeners 1213. The positioning post 1211 is fixed to the decorative panel body 1212, and the set of first stiffeners 1213 connects the outer peripheral surface of one of the first positioning posts 1211 to the decorative panel body 1212. A portion of the surface of the decorative panel body 1212 forms the aforementioned first surface 121a, a portion of the surface of the decorative panel body 1212 forms a part of the aforementioned second surface 121b, the outer surface of the positioning post 1211 forms a part of the aforementioned second surface 121b, and the outer surface of the first stiffener 1213 forms a part of the aforementioned second surface 121b. Based on this, a portion of the surface of the first stiffener 1213 forms at least a portion of the positioning region 121b1.

[0060] This increases the overall strength of the decorative panel 121, makes the overall structure of the decorative panel 121 more compact, and facilitates the assembly of the bracket 122 and the decorative panel 121.

[0061] Figures 4-6 In the illustrated embodiment, the number of sets of first ribs 1213 is the same as the number of positioning posts 1211. A set of first ribs 1213 contains multiple first ribs 1213, and these first ribs 1213 are spaced apart circumferentially along the positioning posts 1211. That is, the positioning area 121b1 is a discontinuous plane, and a portion of the surface of one first rib 1213 forms a part of the positioning area 121b1. Specifically, the number of first ribs 1213 in a set can be two, three, or four, etc. In some other embodiments, the number of first ribs 1213 in a set can also be one, meaning the positioning area 121b1 is a continuous plane, and a portion of the surface of one first rib 1213 forms the entire positioning area 121b1. This application does not limit this to any particular embodiment.

[0062] In other embodiments, the decorative panel 121 may not include the first stiffener 1213. The decorative panel 121 includes a boss (not shown in the figure), which is arranged around a positioning post 1211, and the top surface of the boss forms a positioning area 121b1. In other embodiments, the second surface 121b of the decorative panel 121 may also have a groove (not shown in the figure) recessed towards the first surface 121a. The bottom wall of the groove is arranged around a positioning post 1211, and the bottom wall of the groove forms the positioning area 121b1. It should be noted that the multiple positioning areas 121b1 can be formed in the same way or in different ways, and this application does not limit this.

[0063] Please continue reading. Figures 4-6 The decorative panel 121 also includes at least one set of second stiffeners 1214. At least a portion of the second stiffeners 1214 are located on the side of the first stiffener 1213 away from the decorative panel body 1212, along the normal direction of the positioning region 121b1. A set of second stiffeners 1214 is connected to the outer peripheral surface of a positioning post 1211 and is fitted between the outer peripheral surface of the positioning post 1211 and the inner peripheral surface of the limiting hole 122a2; that is, the positioning post 1211 is fitted into the limiting hole 122a2 by the second stiffeners 1214.

[0064] In this way, the second stiffener 1214 is thinner and easier to deform. When there are manufacturing tolerances between the decorative panel 121 and the bracket 122, the second stiffener 1214 and the positioning post 1211 can be smoothly fitted into the limiting hole 122a2, thereby reducing the assembly difficulty of the decorative panel 121 and the bracket 122.

[0065] Figures 4-6In the illustrated embodiment, the number of sets of second stiffeners 1214 is less than the number of positioning posts 1211, meaning that the outer peripheral surfaces of some positioning posts 1211 are not connected to the second stiffeners 1214, while the outer peripheral surfaces of some positioning posts 1211 are connected to the second stiffeners 1214. In some examples, the second stiffeners 1214 can be entirely located on the side of the first stiffener 1213 away from the decorative panel 121 body and connected to the first stiffener 1213, thereby reducing the design and manufacturing difficulty of the first stiffener 1213, the second stiffeners 1214, and the positioning posts 1211. In other examples, the second stiffeners 1214 can also be partially located on the side of the first stiffener 1213 away from the decorative panel body 1212, and based on this, the second stiffeners 1214 can be connected to the decorative panel body 1212. In some other embodiments, the number of sets of second stiffeners 1214 may be the same as the number of positioning posts 1211, that is, each positioning post 1211 has a set of second stiffeners 1214 connected to its outer peripheral surface. In still other embodiments, the decorative panel 121 may not include the second stiffeners 1214.

[0066] Based on the above, the decorative panel 121 can be a one-piece molded structure, that is, the decorative panel 121 is a one-piece structural component. In this way, the dimensional accuracy of the multiple positioning posts 1211 and the positioning area 121b1 is well consistent, which can ensure the positioning accuracy of the bracket 122, thereby ensuring the assembly accuracy of the decorative panel 121 and the bracket 122.

[0067] In some examples, the decorative panel 121 can be made of plastic, such as ABS plastic or polypropylene (PP). The decorative panel 121 can be formed in a mold using an injection molding process, resulting in a lightweight, low-cost, easy-to-process, and easily snap-fit ​​decorative panel 121 to the A-pillar. In other examples, the decorative panel 121 can also be made of metal, such as aluminum or stainless steel. The decorative panel 121 can be formed using a stamping process or metal powder injection molding (MIM) technology, giving the decorative panel 121 a more technologically advanced look.

[0068] As one possible implementation, the positioning post 1211 is welded to the bracket 122 to fix the bracket 122 to the decorative panel 121. In this way, the connection strength between the decorative panel 121 and the bracket 122 is high, which can reduce the risk of loosening and thus make the connection between the two more reliable.

[0069] In some examples, the bracket 122 is made of plastic, such as ABS or PP. In other examples, the bracket 122 may be made of metal, such as aluminum or stainless steel. When the decorative panel 121 is made of plastic, it can be heat-welded to the bracket 122 by passing the free end of the positioning post 1211 through the limiting hole 122a2. When both the decorative panel 121 and the bracket 122 are made of metal, the positioning post 1211 and the bracket 122 can be welded together using welding materials.

[0070] As one possible implementation, please refer to Figure 6 and Figure 7 , Figure 7 for Figure 6 The diagram shows the assembly structure of the bracket 122 and decorative cover 123 from another perspective. The bracket 122 includes a bracket body 1221 and a connecting ear 1222. The bracket body 1221 has a second mounting hole 122b, which is opposite to and extends through the first mounting hole 121c. The connecting ear 1222 is connected to the bracket body 1221 and extends towards the outer periphery of the bracket body 1221. A portion of the surface of the connecting ear 1222 forms a mating area 122a1 that fits against the positioning area 121b1 of the decorative cover 121. Based on this, the decorative cover 123 is connected to the bracket body 1221 and covers the second mounting hole 122b.

[0071] In this way, the second mounting hole 122b of the bracket 122 can be used to install the positioning speaker, and the bracket 122 occupies a small installation area on the decorative panel 121, making it easier to avoid other installation structures.

[0072] Please continue reading. Figure 6 and Figure 7 The limiting hole 122a2 is formed in the connecting ear 1222. In this way, both the mating area 122a1 and the limiting hole 122a2 are located in the connecting ear 1222, making the overall structure of the bracket 122 more compact and facilitating the fabrication of the mating area 122a1 and the limiting hole 122a2.

[0073] Figure 6 and Figure 7 In the illustrated embodiment, there are multiple connecting ears 1222. Specifically, each connecting ear 1222 corresponds to a limiting hole 122a2, with one limiting hole 122a2 provided on one connecting ear 1222. This results in a smaller size for the connecting ears 1222. In other embodiments, the number of connecting ears 1222 may be less than the number of limiting holes 122a2, and some connecting ears 1222 may have two or three limiting holes 122a2.

[0074] In some examples, the bracket 122 can be a one-piece molded structure. For example, the bracket 122 can be a plastic structural part formed by injection molding, or a metal structural part formed by stamping or MIM. In this way, the dimensional accuracy of the mating area 122a1 and the limiting hole 122a2 is better, and there are fewer dimensional links in the assembly with the decorative panel 121, which helps to improve the assembly accuracy between the decorative panel 121 and the bracket 122. In other examples, the bracket 122 can also be a split structure, and the connecting ear 1222 can be fixed to the bracket body 1221 by snap-fit, threaded connection, adhesive, etc.

[0075] Please continue reading. Figure 6 and Figure 7 As one possible implementation, the bracket 122 has multiple connecting holes 122c, which are arranged circumferentially at intervals along the first mounting hole 121c. Specifically, the connecting holes 122c are formed in the bracket body 1221. The decorative cover 123 includes a decorative cover body 1231 and multiple connecting pieces 1232, wherein the surface of the decorative cover body 1231 facing the same direction as the first surface 121a forms the fourth surface 123b of the decorative cover 123. The shape of the decorative cover body 1231 is adapted to the shape of the first mounting hole 121c, and the decorative cover body 1231 is fitted and accommodated within the first mounting hole 121c. The decorative cover body 1231 has the aforementioned sound outlet hole 123a.

[0076] Specifically, there is a clearance fit between the outer peripheral surface of the decorative cover body 1231 and the inner peripheral surface of the first mounting hole 121c. This clearance can be less than or equal to 0.5 mm, meaning that the clearance between a portion of the decorative cover 123 and the first mounting hole 121c is less than or equal to 0.5 mm. For example, this clearance can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc. This ensures smooth assembly of the decorative cover 123 and the decorative panel 121, and also reduces the user's sensitivity to the clearance, preventing the clearance from being too large and resulting in a poor user experience.

[0077] Based on this, the connecting piece 1232 is connected to the decorative cover body 1231 and extends towards the side facing the aforementioned second surface 121b. A portion of the connecting piece 1232 passes through a connecting hole 122c, and the decorative cover 123 is fixed to the bracket 122 via the connecting piece 1232. In this way, the decorative cover 123 can be assembled onto the bracket 122 using a tooling. Part of the tooling surface can conform to the outer surface of the assembly structure formed by the decorative cover 123 and the bracket 122, or it can conform to the outer surface of the decorative panel assembly 12. Thus, during the process of assembling the decorative cover 123 onto the bracket 122 and assembling the bracket 122 onto the decorative panel 121, the position of the decorative cover 123 relative to the bracket 122 can be finely adjusted, and the position of the decorative cover 123 relative to the decorative panel 121 can also be finely adjusted, which helps to reduce the surface difference between the outer surface of the decorative cover 123 and the outer surface of the decorative panel 121.

[0078] The material of the decorative cover 123 can be the same as or different from that of the bracket 122. In some examples, the decorative cover 123 can be a metal structural component. In this way, the surface of the decorative cover 123 can have a delicate texture and a strong visual effect of light reflection, which can improve the overall appearance of the vehicle 100 and also ensure the sound quality of the high-frequency part of the sound emitted by the speaker.

[0079] In some examples, the end of the connecting piece 1232 located away from the decorative cover body 1231 in the connecting hole 122c can be bent to form a buckle, through which the decorative cover 123 is snapped onto the bracket 122. In other examples, the connecting piece 1232 can also be connected and fixed to the bracket 122 by means of bonding, welding, etc., thereby fixing the decorative cover 123 to the bracket 122.

[0080] In some other embodiments, the decorative cover 123 may not include the connecting piece 1232, and the decorative cover 123 and the bracket 122 are integrally formed, thus the manufacturing efficiency of the decorative cover 123 and the bracket 122 is relatively high.

[0081] The above embodiments use the A-pillar interior panel assembly of vehicle 100 as an example for the decorative panel assembly 12. In other embodiments, the decorative panel assembly 12 can also be a decorative panel assembly for electronic products such as audio equipment, or an interior decorative panel assembly or an exterior decorative panel assembly for buildings.

[0082] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
