Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, specifically to a horn cover assembly, a vehicle interior system, and a vehicle. Background Technology

[0002] As the automotive consumer market continues to upgrade, users' demands for in-car interactive experiences and personalized decorations are increasing. Ambient lighting, as a core element in creating an emotional in-car environment, has rapidly expanded its application from high-end models to mainstream models. Under this trend, the integrated design of ambient lighting and audio speakers, with its immersive audiovisual experience, has become a hallmark feature of high-end electric vehicles, showcasing a sense of technology and luxury.

[0003] However, traditional vehicle models face multiple technical bottlenecks when implementing this integrated solution: First, there is a structural conflict between the sound transmission requirements of the speakers and the light transmission requirements of the ambient lighting. Traditional speaker covers often use a dense perforation design to ensure sound quality, resulting in uneven light distribution. Second, the complexity of the installation structure significantly increases the assembly process, not only raising production costs but also making it difficult to meet the vehicle's lightweight design goals due to the stacking of multiple components. Third, the circuitry, brackets, and other structures behind the light-transmitting material are prone to perspective distortion, compromising the purity of the light. Fourth, the uniformity of halo-style lighting effects and the problem of halo superposition result in a lack of layered changes in the lighting, making it impossible to achieve refined light and shadow effects such as gradients and zoned effects. These limitations mean that traditional speaker covers can generally only achieve single-tone, halo-style lighting effects, which falls far short of users' expectations for a high-quality in-car atmosphere. Summary of the Invention

[0004] The purpose of this invention is to provide a horn cover assembly, a vehicle interior system, and a vehicle, which have a high degree of integration and can achieve light emission in the central area of ​​the horn.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, this utility model discloses a speaker grille assembly, including a base, a light-emitting element, a light-guiding element, a flexible light-guiding layer, and a decorative element; the base is integrally formed and includes a light-guiding area and a non-light-guiding area, wherein a sound outlet hole is provided through the light-guiding area at a position corresponding to the speaker; the light emitted by the light-emitting element is transmitted to the light-guiding area through the light-guiding element, forming an annular light ring around the sound outlet hole; the flexible light-guiding layer is arranged between the base and the decorative element, transmitting the light from the edge of the sound outlet hole in the light-guiding area to the center of the sound outlet hole, forming a light curtain covering the sound outlet hole; the decorative element is connected to the base, and an array of mesh holes is provided at a position corresponding to the sound outlet hole on the base.

[0007] Furthermore, the light-guiding area extends along the wall of the sound outlet hole in a direction away from the decorative piece to form an extension sleeve capable of guiding light.

[0008] Furthermore, the light guide element includes a first segment and a second segment. The first segment is snapped and fixed to the outside of the extension sleeve, and the first segment is in contact with the side of the light guide area. One end of the second segment is connected to the first segment, and the other end is connected to the light-emitting element.

[0009] Furthermore, when the number of sound outlet holes is two or more, the spacing between adjacent sound outlet holes is not less than a preset threshold.

[0010] Furthermore, the array mesh includes circular array meshes and spiral array meshes distributed around the circular array meshes.

[0011] Furthermore, the aperture of the array mesh is reasonably set based on simulation experiments.

[0012] Furthermore, the non-light-guiding area of ​​the base is provided with a first mounting point for fixing the light-emitting element and a second mounting point for fixing the speaker on the side opposite to the decorative piece.

[0013] Furthermore, the central axis of the sound outlet hole and the central axis of the array mesh coincide with the central axis of the speaker sound-emitting area.

[0014] Secondly, this utility model discloses a vehicle interior system, which includes the aforementioned speaker cover assembly.

[0015] Thirdly, this utility model discloses a vehicle that includes the aforementioned vehicle interior system.

[0016] This utility model has the following unexpected beneficial effects:

[0017] 1. The base of this utility model adopts an integrated molding design, combining the light-guiding area and the non-light-guiding area into a single structure. This avoids the component redundancy problem caused by the separate speaker mounting structure in traditional solutions, significantly improving the product's integration level. This not only simplifies the overall structure but also reduces the number of connectors and processes required for assembly, helping to lower production costs and aligning with the vehicle's lightweight design goals. Furthermore, the non-light-guiding area of ​​the base effectively shields the rear circuitry, brackets, and other components, reducing light transmission and improving the purity of the light.

[0018] 2. This utility model achieves diversified lighting presentation through layered light guiding. The light guiding element transmits light from the light-emitting element to the light guiding area, forming a ring-shaped light circle around the sound outlet hole, retaining the ambiance of traditional halo lighting effects. The flexible light guiding layer further transmits light from the edge of the sound outlet hole to the center, forming a light curtain covering the sound outlet hole, breaking through the limitation of the central area not being able to emit light in the traditional solution, and achieving a combined effect of ring-shaped light circle and full-area light curtain. In addition, after the light is transmitted twice through the light guiding element and the flexible light guiding layer, it can naturally form a gradual transition of light and shadow layers, solving the problem of the traditional halo lighting effect being monotonous and lacking a sense of layering, and meeting the needs of high-end models for refined light and shadow effects.

[0019] 3. The array mesh design on the decorative part of this utility model not only ensures the sound output efficiency of the speaker, but also avoids the problem of uneven light distribution caused by traditional dense openings through the regular arrangement of the mesh.

Detailed Implementation

[0030] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] In one embodiment, the present invention provides a speaker grille assembly, see below. Figures 1 to 6 As shown, the speaker enclosure assembly includes a base 1, a light-emitting element 2, a light-guiding element 3, a flexible light-guiding layer 4, and a decorative element 5. The base 1 is integrally formed and includes a light-guiding area 11 and a non-light-guiding area 11. The light-guiding area 11 has a through-hole 13 at the position corresponding to the speaker 6. The light emitted by the light-emitting element 2 is transmitted to the light-guiding area 11 through the light-guiding element 3, forming a ring of light around the through-hole 13. The flexible light-guiding layer 4 is arranged between the base 1 and the decorative element 5, transmitting the light from the edge of the through-hole 13 in the light-guiding area 11 to the center of the through-hole 13, forming a light curtain covering the through-hole 13. The decorative element 5 is connected to the base 1, and the decorative element 5 has an array of mesh holes 51 at the position corresponding to the through-hole 13 on the base 1.

[0033] The base 1 of this invention adopts a one-piece molding design, integrating the light guide area 11 and the non-light guide area 12 into a single structure. This avoids the component redundancy problem caused by the separate speaker mounting structure in traditional solutions, significantly improving the integration level of the product. This not only simplifies the overall structure but also reduces the number of connectors and processes required for assembly, helping to reduce production costs and aligning with the design goal of lightweight vehicles. Furthermore, the non-light guide area 12 of the base 11 effectively shields the rear circuitry, brackets, and other components, reducing light transmission and improving the purity of the light.

[0034] For example, the light-guiding area 11 is made of a light-transmitting material and serves as a light guide; the non-light-guiding area 12 is made of opaque plastic and serves as a load-bearing component. The light-guiding area 11 and the non-light-guiding area 12 are integrally molded using two-color injection molding. The integral molding of the light-transmitting material and the opaque plastic using two-color injection molding ensures the efficient light-guiding performance of the light-guiding area 11, meeting the light transmission requirements of the ambient light, while the structural characteristics of the opaque plastic provide the entire base 1 with stable load-bearing capacity. This allows a single component to possess both functionality and structural integrity, avoiding problems such as loose connections and gaps that may occur in traditional split structures. Furthermore, at the production and assembly level, the two-color injection molding process completes the molding and bonding of the two materials in one step, eliminating the need for secondary assembly of the light-guiding component and the load-bearing component. This not only simplifies the production process and improves production efficiency but also reduces assembly errors and enhances the overall dimensional accuracy and consistency of the product. Meanwhile, from a visual perspective, the one-piece molding design eliminates the physical splicing traces between the light guide area and the non-light guide area, making the transmission of light in the light guide area 11 smoother and more natural. At the same time, the non-light guide area 12 can effectively shield the internal structure, avoid light leakage or see-through phenomenon, and ensure the purity and aesthetics of the light presentation.

[0035] This invention achieves diversified lighting presentation through layered light guiding. The light guiding element 3 conducts the light from the light-emitting element 2 to the light guiding area 11, forming a ring-shaped light circle around the sound outlet hole 13, retaining the ambiance of traditional ring-shaped lighting effects. The flexible light guiding layer 4 further conducts the light from the edge of the sound outlet hole 13 to the center, forming a light curtain covering the sound outlet hole 13. This overcomes the limitation of the central area not being able to emit light in traditional solutions, achieving a combined effect of a ring-shaped light circle and a full-area light curtain. In addition, after the light is conducted twice by the light guiding element 3 and the flexible light guiding layer 4, it can naturally form a gradual transition of light and shadow layers, solving the problem of the traditional ring-shaped lighting effect being monotonous and lacking a sense of layering, and meeting the needs of high-end models for refined light and shadow effects.

[0036] The array mesh 51 design on the decorative piece 5 of this utility model not only ensures the sound output efficiency of the speaker, but also avoids the problem of uneven light distribution caused by traditional dense openings through the regular arrangement of the mesh.

[0037] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figures 3 to 5 As shown, the light guiding area 11 extends along the wall of the sound outlet hole 13 toward the direction away from the ornament 5 to form an extension sleeve 14 capable of guiding light.

[0038] The extension sleeve 14 allows light to extend beyond a planar path, extending it along the wall of the sound outlet hole 13. This expands the original annular light ring and light curtain into a three-dimensional light and shadow space, breaking through the limitations of traditional planar lighting effects. It creates a more layered and immersive in-car atmosphere, making the lighting more dynamic and expressive, meeting diverse lighting needs. Furthermore, the extension sleeve 14 serves both as part of the light guide structure, enabling three-dimensional light transmission, and its extension along the hole wall reinforces the edges of the sound outlet hole 13. Simultaneously, the extension sleeve 14 is integrally formed with the light guide area 11, eliminating the need for additional three-dimensional light guide components. This achieves a three-dimensional lighting effect without increasing structural complexity.

[0039] In addition, the three-dimensional lighting effect works in conjunction with the array mesh 51 of the decorative piece 5. The light is transmitted through the extension sleeve 14 and then through the array mesh 51, which makes the light and shadow of the light curtain and the ring light ring more visually coherent and natural, enhances the integration of the light and the overall shape of the speaker cover, and improves the aesthetics and sophistication of the product.

[0040] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 1 As shown, the light guide element 3 includes a first segment 31 and a second segment 32. The first segment 31 is snapped and fixed to the outside of the extension sleeve 14, and the first segment 31 is in contact with the side of the light guide area 11. One end of the second segment 32 is connected to the first segment 31, and the other end is connected to the light-emitting element 2.

[0041] In this preferred embodiment, the first segment 31 of the light guide element 3 is directly snapped onto the outside of the extension sleeve 14, achieving a close fit with the light guide area 11 and the extension structure, reducing the loss of light in the transmission path, and ensuring that the light from the light-emitting element 2 can be transmitted to the light guide area 11 and the extension sleeve 14 more efficiently, providing a stable light source foundation for the presentation of three-dimensional lighting effects.

[0042] Furthermore, the snap-fit ​​fixing method between the first segment 31 and the extension sleeve 14 does not require additional fasteners, which can ensure a reliable connection between the light guide element 2 and the base 1 and simplify the assembly process. Meanwhile, the second segment 32, as a transition structure connecting the light-emitting element 2 and the first segment 31, can flexibly adapt to the installation position of the light-emitting element 2, reduce the restrictions on the layout of the light-emitting element 2, and improve the assembly flexibility of the overall structure.

[0043] For example, see Figure 4As shown, a protrusion is integrally formed on the surface of the light guide area 11 away from the decorative piece 5, near the extension sleeve 14. The protrusion and the extension sleeve 14 together form a snap-fit ​​groove 15 that is adapted to the light guide element 3.

[0044] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 3 As shown, when the number of sound outlet holes 13 is two or more, the spacing L between adjacent sound outlet holes 13 is not less than a preset threshold.

[0045] This design effectively prevents the lights from overlapping and interfering with each other in different sound outlet areas 13, ensuring that the annular light ring and light curtain corresponding to each sound outlet 13 maintain clear boundaries and independent light and shadow shapes. This makes the overall lighting more regular and orderly, improving the refinement and controllability of the light and shadow effects. The clearly separated light and shadow areas make the interior lighting layout more layered, avoiding visual confusion caused by overlapping lights, enhancing the aesthetics and comfort of the lighting effects, and further improving the user's perception of the interior atmosphere.

[0046] For example, the preset threshold is set to 18mm.

[0047] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 6 As shown, the array mesh 51 includes circular array meshes and spiral array meshes distributed around the circular array meshes.

[0048] In this preferred embodiment, the mesh patterns of the two array types form a rich layer of patterns. The regularity of the circular array and the dynamism of the spiral array complement each other, maintaining the sense of order on the surface of the trim while enhancing the visual tension through the difference in shape. This makes the appearance of the speaker cover assembly more stylish and refined, and it integrates better with the overall interior decoration style of the vehicle.

[0049] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 6 As shown, the aperture of the array mesh 51 is reasonably set based on simulation experiments.

[0050] In this preferred embodiment, the aperture set based on simulation experiments can accurately match the light transmission characteristics of the light guide element 3 and the flexible light guide layer 4, ensuring that the light is evenly distributed when passing through the array mesh 51, avoiding local over-brightness due to excessively large apertures or light blockage due to excessively small apertures, so that the light and shadow effects of the light curtain and the ring aperture are more in line with the design expectations, presenting a more delicate and pure visual effect.

[0051] Furthermore, the simulation experiment can simulate the effect of different apertures on sound wave transmission. By reasonably setting the aperture, it is possible to ensure light transmission while minimizing the obstruction to the speaker's sound output, achieving a precise balance between light transmission and sound transmission performance, and avoiding sound quality loss due to unreasonable aperture design.

[0052] Meanwhile, simulation experiments can predict the structural strength and processing feasibility of the ornament 5 under different apertures in advance, ensuring that the set aperture will not increase the processing difficulty due to being too small, nor will it affect the overall structural stability of the ornament due to being too large, thereby ensuring the production feasibility and durability of the product while meeting functional requirements.

[0053] For example, see Figure 7 As shown, by reasonably setting the aperture of the array mesh 51, it is beneficial to diffuse light evenly, make the ring light emission boundary clear, and achieve orderly distribution of light and shadow, which meets the decorative requirements of the speaker cover assembly and enhances the sense of refinement of the interior atmosphere.

[0054] See Figure 8 As shown, by adding the flexible light guide 4, the whole structure emits light in a spiral and ring array. The light gradually diffuses from the center outward. By using the mesh array, the light passes through and forms a layered gradient of light and shadow, making the light transition natural and avoiding local over-brightness or under-brightness, thus creating an immersive and fluid in-car atmosphere.

[0055] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 4 As shown, the non-light-guiding area 12 of the base 1, on the side opposite to the decorative piece 5, is provided with a first mounting point for fixing the light-emitting element 2 and a second mounting point for fixing the speaker 6.

[0056] In this preferred embodiment, the mounting points of the light-emitting element 2 and the speaker 6 are centrally located in the non-light-guiding area 12 of the base 1, achieving integrated assembly of multiple components. This avoids the structural redundancy caused by the dispersed installation of components in traditional solutions, further enhancing the overall integration of the speaker enclosure assembly and making the layout of each component more compact and orderly. The unified mounting point design simplifies the assembly process, eliminating the need to design complex fixing structures for the light-emitting element 2 and the speaker 6 separately. This reduces assembly steps and positioning adjustment processes, helping to improve assembly efficiency on the production line and reduce labor costs.

[0057] The non-light-guiding area 12 of the base 1 has a strong load-bearing capacity. Setting the first and second mounting points in this area can provide a stable fixed foundation for the light-emitting element 2 and the speaker 6, reduce the impact of vibration during vehicle operation on the component connection, ensure stable light output of the light-emitting element 2 and reliable sound quality performance of the speaker 6, and improve the durability of the product.

[0058] This arrangement makes the light-emitting element 2, the speaker 6 and the base 1 form an organic whole, avoiding the mismatch between components caused by scattered installation, ensuring the accurate alignment of the light-emitting element 2 and the light guide element 3, and the reasonable matching of the positions of the speaker 6 and the sound outlet hole 13, thereby ensuring the stable performance of the lighting effect and sound transmission.

[0059] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 4 As shown, the central axis 7 of the sound outlet hole and the central axis 8 of the array mesh coincide with the central axis 9 of the speaker sound-emitting area.

[0060] On the one hand, the coincidence of the central axes of the three ensures that the sound emitted by the speaker 6 can be transmitted to the outside world through the sound outlet hole 13 and the array mesh 51 along the optimal path, reducing the refraction and reflection loss of the sound during the transmission process, reducing the sound quality distortion caused by path deviation, ensuring the purity and propagation efficiency of the sound, and allowing the speaker's sound production effect to be fully utilized.

[0061] On the other hand, the axial alignment design allows light to be symmetrically distributed with the center of the sound outlet hole 13 and the array mesh 51 as a reference after passing through the light guide area 11 and the flexible light guide layer 4. This ensures that the light coverage in the array mesh 51 area is more uniform and symmetrical, avoiding local light and shadow shifts or uneven brightness caused by axial offset. This makes the lighting effect and the array mesh 51 layout precisely correspond, improving the overall visual harmony.

[0062] In one embodiment, the present invention also provides a vehicle interior system, which includes the horn cover assembly described in any of the above embodiments.

[0063] In one embodiment, the present invention also provides a vehicle that includes the aforementioned vehicle interior system.

[0064] The vehicles can be, but are not limited to, pure electric vehicles (PEV / BEV), hybrid electric vehicles (HEV), range-extended electric vehicles (REEV), plug-in hybrid electric vehicles (PHEV), new energy vehicles, and gasoline vehicles.

[0065] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
