Description

Technical Field

[0001] This utility model relates to the field of electronic information, and in particular to a car audio system. Background Technology

[0002] Car audio systems are an indispensable and crucial component of modern automobiles, primarily serving to provide drivers and passengers with high-quality audio playback and a superior auditory experience. They are not only the core of the infotainment system, effectively playing music, navigation prompts, and communication content, but also vital for creating a comfortable driving environment and enhancing the overall driving experience. With the deepening integration of the automotive industry and consumer electronics technology, users are increasingly demanding higher sound quality, greater functionality, and easier installation from car audio systems.

[0003] However, traditional car audio systems are mostly installed to fit the internal structure and dimensions of specific car models, meaning that the specifications and installation methods of the audio system are closely related to the vehicle. This adaptation method significantly limits both car production and audio system manufacturing, requiring automakers and audio suppliers to design and produce specifically for different car models. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0017] Example: This example provides a car audio system. See [link / reference]. Figure 1-4 Specifically, it includes a car audio unit 1, a housing 14 mounted on the car audio unit 1, and an annular external bracket 11 mounted on the housing 14. Two arc-shaped mounting strips 12 are rotatably mounted at least equidistantly on one side of the external bracket 11, and each mounting strip 12 has an arc-shaped mounting groove 13. Two connectors 5 connected to the housing 14 are mounted at least equidistantly on the other side of the external bracket 11. The external bracket 11 has a drive assembly 2 inside for synchronously driving the mounting strips 12 to rotate.

[0018] In this embodiment, the external bracket 11 serves as the base platform for the entire adjustable mechanism, internally housing the drive assembly 2 and externally connecting the audio system and the vehicle. The arc-shaped mounting strip 12 and mounting groove 13 are key to achieving flexible installation. Their arc design allows the mounting groove 13 to cover a fan-shaped adjustment area when the mounting strip 12 rotates, providing a much larger tolerance range for the installation position than ordinary round holes. The mounting bolts on the vehicle can pass through the arc-shaped mounting groove 13. When the audio system's installation position needs adjustment, it is not necessary to move the entire audio system; instead, by rotating these mounting strips 12, the mounting groove 13 slides relative to the bolt positions on the vehicle, thereby fine-tuning the final installation point of the audio system within a large range.

[0019] In the specific implementation process, such as Figure 2 and Figure 4As shown, the drive assembly 2 includes a drive ring 23 rotatably mounted in the groove in the middle of the outer bracket 11, a rotating shaft 21 fixedly mounted at the end of the mounting strip 12, gears 22 fixedly mounted on the rotating shaft 21, and toothed plates 24 of the same number as gears 22 mounted on the inner side of the drive ring 23. The gears 22 mesh with the toothed plates 24, and two fixing members are symmetrically arranged between the outer bracket 11 and the drive ring 23.

[0020] In this embodiment, the drive ring 23 serves as the core driving component, synchronously transmitting the user's rotational operation to all mounting strips 12. The gear 22 and the toothed plate 24 form an "internal gear ring" transmission mechanism, precisely converting the rotational motion of the drive ring 23 into the synchronous rotation of each mounting strip 12. When the angle of the mounting strip 12 needs adjustment, the operator manually rotates the drive ring 23. The toothed plate 24 on the inner side of the drive ring 23 simultaneously drives all the gears 22 meshing with it. Since all gears 22 are of the same specification and synchronously driven by the toothed plate 24, they drive their respective shafts 21 and mounting strips 12 to rotate precisely and synchronously by the same angle. The mounting grooves 13 on the mounting strips 12 align with the bolt positions on the vehicle, facilitating the installation of the car audio system.

[0021] In the specific implementation process, such as Figure 2 and Figure 4 As shown, the fastener includes a first bolt 3 that runs vertically through the drive ring 23 and the outer bracket 11, with a nut on the first bolt 3 fitting against the inner side of the drive ring 23. The first bolt 3 serves as both a locating pin and a locking bolt. When tightened, it firmly secures the drive ring 23 and the outer bracket 11 together.

[0022] In the specific implementation process, such as Figure 2 and Figure 4 As shown, an anti-slip ring 4, made of rubber, is fixedly installed on the outer wall of the drive ring 23. The anti-slip ring 4 increases friction, making it easier and less prone to slipping when manually rotating the drive ring 23.

[0023] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the connector 5 includes a fixing plate 51 installed on the side of the external bracket 11. A screw 52 is threaded between the fixing plate 51 and the external bracket 11. A positioning element connected to the outer shell 14 is installed on the fixing plate 51.

[0024] In this embodiment, the fixing plate 51 and screws 52 fix the base of the connecting mechanism to the external bracket 11. The fixing plate 51 can be adjusted along the side of the external bracket 11 to align the positioning member with the mounting position on the housing 14.

[0025] In the specific implementation process, such as Figure 2 and Figure 3As shown, the positioning component includes fixed posts 6 fixedly installed at both ends of the fixed plate 51, a connecting frame 61 is movably inserted into the fixed post 6, a second bolt 62 passes through between the connecting frame 61 and the fixed post 6, and the end of the connecting frame 61 matches the bolt position on the outer shell 14.

[0026] In this embodiment, the fixed post 6, the connecting frame 61, and the second bolt 62 form a "retractable snap-fit" structure. The connecting frame 61 can extend and retract within the fixed post 6 to adjust the distance between the connecting frame 61 and the outer shell 14. After adjusting the position of the connecting frame 61, the second bolt 62 is inserted through the fixed post 6 and the connecting frame 61, and the nut on the second bolt 62 is tightened to press the connecting frame 61 firmly onto the fixed post 6.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
