Description

Technical Field

[0001] This invention relates to the field of automotive interior technology, and more particularly to a speaker ambient lighting structure for an automotive dashboard. Background Technology

[0002] As the automotive consumer market increases its demand for interior comfort and personalization, ambient lighting and speakers have become important components of automotive interiors. Ambient lighting is used to create an interior atmosphere by illuminating specific areas and enhancing the visual experience, while speakers are used to output audio signals to meet the user's auditory needs. As the core area of ​​the automotive interior, the dashboard has high requirements for its space utilization, functionality, and aesthetic refinement. Therefore, it is often necessary to arrange speakers and ambient lighting in this area to balance audio functionality and atmosphere creation.

[0003] In existing technology, the arrangement of speakers and ambient lighting in the dashboard area is usually designed and installed independently, with the speakers belonging to different mounting systems. For vehicles that require both speakers and ambient lighting, installation space is typically reserved separately for each on the dashboard.

[0004] Therefore, existing technologies have the following problems in practical applications: Speakers and ambient lighting use independent mounting systems, each requiring separate space within the dashboard. The central area of ​​the dashboard has limited available space due to the need for small speaker grilles to maintain a refined appearance. This independent mounting method limits the space available for some models, preventing the simultaneous placement of speakers and ambient lighting. A trade-off must be made between audio and ambient lighting functions, failing to meet users' demands for multi-functional interiors. Secondly, if ambient lighting is to be installed around the speakers, independent light sources and light guides are required. The lack of a coordinated mounting structure between these components and the speakers not only increases the total number of interior parts but also necessitates separate positioning and fixing of the speakers, light sources, and light guides during assembly, increasing assembly steps and time. Furthermore, the fit between components is difficult to control, leading to decreased overall structural stability and potential loosening of components after prolonged use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a speaker ambient light structure for an automotive dashboard.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment proposes a speaker ambient light structure for a car dashboard, including: a base 5, an ambient light, and a speaker assembly 6; as Figure 5 , Figure 7As shown, the base 5 is provided with a boss 51 and a receiving chamber 54. The receiving chamber 54 is located on one side of the boss 51. The boss 51 has a receiving cavity 53 inside. The top of the boss 51 is open. The outer periphery of the boss 51 has a groove 52. The groove 52 is annularly wrapped around the outside of the boss 51, and one side of the groove 52 extends to the receiving chamber 54. The ambient light includes a lamp head 8 and a light guide 7. The lamp head 8 is installed in the receiving chamber 54. The light guide 7 is embedded in the groove 52, and one end of the light guide 7 is connected to the lamp head 8. The speaker assembly 6 is installed in the receiving cavity 53 of the boss 51.

[0021] The structure integrates a boss 51 and a receiving chamber 54 via a base 5. The boss 51 has an opening at the top and an annular groove 52 on its outer periphery, extending into the receiving chamber 54. The ambient light lamp head 8 is mounted in the receiving chamber 54, and the light guide 7 is embedded in the groove 52 and connected to the lamp head 8. The speaker assembly 6 is mounted within the receiving cavity 53 of the boss 51. This layout allows the light guide 7 to surround the speaker assembly 6, utilizing the compact structure of the base 5 to achieve the coexistence of the ambient light and the speaker within a limited space. As a light guiding element, the light guide 7 evenly diffuses the light emitted from the lamp head 8 along an annular path, avoiding the extra space required for separately arranging the light source and light guide strip. The design of the boss 51 and groove 52 in the base 5 allows the light guide 7 and the speaker to share a mounting base, reducing the number of parts and assembly complexity, while improving the overall structural integrity and solving the problem of limited functionality caused by space constraints in the center of the dashboard.

[0022] like Figure 5 , Figure 6 As shown, the side wall of the boss 51 is provided with multiple slots 56, and the outer side of the speaker assembly 6 is provided with multiple protrusions 61. The protrusions 61 of the speaker engage in the slots 56 of the boss 51, eliminating the need for additional bolts, screws or other fasteners. This simplifies the assembly process between the speaker assembly 6 and the boss 51 of the base 5 and reduces assembly time. At the same time, the cooperation between the multiple slots 56 and the protrusions 61 can position the speaker assembly 6 circumferentially, preventing radial displacement of the speaker assembly 6 during use, ensuring the stability of the speaker assembly 6 during operation, and reducing noise or functional failures caused by loose components.

[0023] The outer wall of the groove 52 is provided with a plurality of buckles 55, and the inner side of the buckles 55 has hooks, which press on the light guide 7.

[0024] The hook pressing against the light guide 7 provides a limiting position, preventing it from shifting or falling out within the groove 52. This is especially important during vehicle travel when encountering bumps, preventing the connection between the light guide 7 and the lamp head 8 from loosening and ensuring stable light guiding. This structure solves the problem of the light guide 7 needing an independent bracket for fixation, which can lead to installation deviations due to interference between the bracket and other components. The snap fastener 55 is directly integrated into the outer wall of the groove 52, eliminating the need for an additional bracket and reducing the number of components. The snap fastener 55 is made of a flexible plastic material, allowing it to be slightly pried open during installation. After the light guide 7 is inserted into the groove 52, the snap fastener 55 returns to its original position, allowing the hook to naturally press against the light guide 7, facilitating assembly and providing sufficient clamping force.

[0025] like Figure 3 , Figure 4 As shown, the speaker ambient light structure also includes a mask 1 and a light-transmitting plate 3. The mask 1 has an opening in the middle. The light-transmitting plate 3 is installed on the lower side of the mask 1 and is located at the opening. The base 5 is installed on the lower side of the light-transmitting plate 3.

[0026] As an outer component, the mask 1 protects the internal light-transmitting plate 3, base 5, and other components, preventing dust and debris from entering and affecting their function. The light-transmitting plate 3, located between the mask 1 and base 5, can be made of transparent or semi-transparent plastic, allowing light from the ambient light head 8 transmitted through the light guide 7 to pass through smoothly. Simultaneously, it shields the base 5 and the internal speaker assembly 6 and ambient light components, preventing direct exposure of the internal structure and its appearance. The combination of the mask 1 and the light-transmitting plate 3 ensures both the lighting effect of the ambient light and enhances the overall aesthetics and protective performance of the structure.

[0027] The light-transmitting plate 3 has a raised structure in the middle, which is located on the upper side of the light guide 7. The raised structure has an opening in the middle, which is located on the upper side of the speaker assembly 6, and a mesh cover 31 is provided at the opening.

[0028] The raised structure of the light-transmitting plate 3 corresponds to the opening of the mask 1. The opening in the middle of the raised structure provides a channel for the sound propagation of the speaker assembly 6, reducing the propagation loss of sound and light source and improving the stereo sound effect in the vehicle. The mesh cover 31 covers the opening, which can prevent foreign objects from entering the speaker assembly 6 and causing damage, while not obstructing the sound propagation and ensuring the audio output effect of the speaker.

[0029] The inner wall of the raised structure of the light-transmitting plate 3 is provided with multiple protrusions 32 and is treated with blackening.

[0030] The protrusions 32 on the inner wall can refract the light emitted from the light guide 7, making the light distribution more uniform and avoiding localized areas of excessively high or low brightness. The blackening treatment absorbs some stray light, reducing light reflection from the inner wall of the raised structure onto the windshield and preventing reflected light from affecting the driver's vision. The synergistic effect of the protrusions 32 and the blackening treatment can block some light, making the emitted light softer and preventing excessive glare from affecting the driver's vision, thus optimizing the lighting effect and improving driving safety.

[0031] like Figure 1 , Figure 8 As shown, the mask 1 is also provided with an inner cover 9 and an outer cover 2. The inner cover 9 and the outer cover 2 are located at the opening of the mask 1. The inner cover 9 is located inside the outer cover 2. Both the inner cover 9 and the outer cover 2 are upwardly arched arc-shaped masks 1. The inner wall of the inner cover 9 is provided with a shaped structure.

[0032] The arc-shaped inner cover 9 and outer cover 2 can concentrate sound and enhance the three-dimensional effect inside the car. The inner wall of the inner cover 9 can be designed with stripes, dots or other decorative patterns. When the ambient light shines through, the shape can make the light form corresponding light and shadow effects, enhancing the decorative atmosphere inside the car.

[0033] The inner cover 9 and the outer cover 2 cover the opening of the mask 1, forming a layer of protection with the light-transmitting plate 3, while not affecting the light transmitted through the light-transmitting plate 3. The shape and structure are coordinated with the light of the ambient light, making the function and decoration more closely integrated.

[0034] like Figure 9 , Figure 10 , Figure 12 As shown, the inner cover 9 is provided with a first mounting hole 94 and a second mounting hole 95 on its rear side, and is mounted on the face mask 1 through the first mounting hole 94. The outer cover 2 is provided with a threaded hole 23 on its rear side that connects to the second mounting hole 95.

[0035] The inner cover 9 achieves a reliable connection with the face mask 1 through the first mounting hole 94. The outer cover 2 is fixed to the inner cover 9 by the engagement of the threaded hole 23 with the second mounting hole 95 of the inner cover 9 and by using fasteners such as bolts, thereby achieving indirect fixation between the outer cover 2 and the face mask 1.

[0036] The inner wall of the outer cover 2 is also provided with a limit block 21 and a buckle 22, and the outer wall of the inner cover 9 is provided with a limit buckle 91 and a through groove 92. The limit buckle 91 of the inner cover 9 is installed at the limit block 21 position of the outer cover 2, and the buckle 22 of the outer cover 2 is inserted into the through groove 92 position of the inner cover 9.

[0037] The cooperation between the limiting block 21 and the limiting buckle 91 can restrict the relative position of the inner cover 9 and the outer cover 2 in the circumferential direction, while the cooperation between the buckle 22 and the through groove 92 can restrict the relative position of the two in the axial direction, forming a double positioning structure, which makes the connection between the inner cover 9 and the outer cover 2 more secure, and can maintain a stable relative position even when the car is bumpy, avoiding appearance damage or functional impact caused by displacement.

[0038] like Figure 8 , Figure 11 , Figure 12 As shown, the speaker ambient light structure also includes a decorative ring 4, which is obliquely arranged between the faceplate 1 and the inner cover 9. The bottom side of the decorative ring 4 is provided with a lower insert plate 41, and the upper side is provided with an upper insert plate 42 and a limiting plate 43. The bottom side of the light-transmitting plate 3 is provided with a fixing plate 33. The lower insert plate 41 is installed on the fixing plate 33. The limiting plate 43 is inserted into the other side of the through groove 92 of the inner cover 9, and the upper insert plate 42 is inserted into the slot 93 of the inner cover 9.

[0039] The inclined arrangement of the decorative ring 4 creates a transition between the face mask 1 and the inner cover 9, enhancing the sense of layering and refinement of the appearance. Furthermore, the decorative ring 4 can be made of a different color or material than the inner cover 9 and the outer cover 2, enriching the visual effect. The connection between the lower insert plate 41 and the fixing plate 33 of the light-transmitting plate 3, the cooperation between the limiting plate 43 and the through groove 92 of the inner cover 9, and the cooperation between the upper insert plate 42 and the slot 93 of the inner cover 9 form a multi-directional fixing structure. This ensures that the decorative ring 4 can be stably installed and also helps to strengthen the connection between the face mask 1, the inner cover 9, and the light-transmitting plate 3. The decorative ring 4 serves both a decorative and structural strengthening function.

[0040] In summary, the speaker ambient light structure provided in this embodiment, by creating a recess 52 around the speaker and installing a light guide 7, allows for the configuration of ambient lights without occupying too much space in the compact space of the dashboard. This not only enhances the in-vehicle audio effect but also improves the in-vehicle atmosphere, enhancing the rhythm of the audio and the premium feel of the vehicle interior. The structure is simple, reasonable, and occupies little space.

[0041] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
