Description

Technical Field

[0001] This utility model relates to the field of automotive audio panel technology, and in particular to a dustproof mechanism and an automotive audio panel. Background Technology

[0002] Car audio systems are sound-emitting devices designed to alleviate the boredom of drivers and passengers during travel. To maintain the aesthetics of the vehicle interior, car audio systems are installed inside the vehicle, and a panel is mounted on the outside of the car audio system for decorative purposes.

[0003] Existing car audio panels have a plate-like structure and a dust cover installed on the panel. While this serves to prevent dust and does not affect sound transmission, the dust cover still has tiny holes that allow sound to pass through. Dust particles in the air can still enter the car audio system through these tiny holes, resulting in poor dust prevention and affecting the playback quality.

[0004] Therefore, those skilled in the art have proposed a dustproof mechanism and a car audio panel to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the above-mentioned dustproof mechanism and car audio panel, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a dustproof mechanism that solves the problem of poor dustproof effect by using only a dustproof cover.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dustproof mechanism, comprising:

[0009] A dust-blocking and dust-collecting unit, comprising a circular cover plate, a dust cover installed at the front end of the circular cover plate, and a cylinder connected to the rear end of the circular cover plate for containing acoustic sponge;

[0010] The quick-release component includes cavities at both ends of the inner cavity of the round cover plate. Each set of cavities is slidably connected to a movable component, and a locking pin is installed on the movable component for the assembly and disassembly of the round cover plate.

[0011] As a preferred embodiment of the dustproof mechanism of this utility model, the dust-blocking and dust-collecting unit further includes a movable cover disposed on the cylinder, and the movable cover has multiple sets of through holes communicating with the dustproof cover.

[0013] As a preferred embodiment of the dustproof mechanism of this utility model, the quick-release component further includes a limiting groove formed on the moving part, and a telescopic rod is fixedly connected between the limiting groove and the inner wall of the cavity.

[0014] In a preferred embodiment of the dustproof mechanism of this utility model, a spring is fitted on the outer wall of the telescopic rod, and the spring is located between the limiting groove and the inner wall of the cavity.

[0016] The dustproof mechanism of this utility model has the following advantages: The dustproof cover on the dustproof and dust-collecting unit of this utility model plays a role in blocking dust. When the micro-dust carried in the air flows through the internal channel of the acoustic sponge in the cylinder, the micro-dust will be captured by the continuous and interconnected skeleton inside the acoustic sponge through mechanisms such as inertial collision, interception and diffusion, thus achieving the dust collection function and improving the dustproof effect. By moving the hand block on the quick-release component in the front slot, the moving part can be moved. With the elasticity of the telescopic rod and spring, the locking post can be connected or disengaged with the opening locking hole, realizing the quick installation and removal of the round cover plate. With the magnetic connection between the rotating handle and the magnetic layer, it is convenient to replace the acoustic sponge in the cylinder and avoid it reaching a saturation state, which would affect the dust collection effect.

[0017] The purpose of this invention is to provide a car audio panel that solves the problem that the dustproof effect of car audio panels using only dust covers is not good.

[0018] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a car audio panel, including a dustproof mechanism; and,

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0033] Example 1

[0034] Reference Figure 1 , Figure 4 and Figure 5 This is the first embodiment of the present invention, which provides a dustproof mechanism that can improve the dustproof effect, including:

[0035] The dust-proof and dust-collecting unit 200 includes a round cover plate 201, a dust cover 202 installed at the front end of the round cover plate 201, and a cylinder 203 connected to the rear end of the round cover plate 201 for containing acoustic sponge.

[0036] It should be noted that acoustic sponge refers to foam with an open-cell structure. Its internal skeleton forms a continuous and interconnected three-dimensional network in which sound waves can easily propagate with very little energy loss and without affecting the propagation of sound. When air carrying dust particles flows through the intricate internal channels of the sponge, the dust particles are captured by the skeleton through mechanisms such as inertial collision, interception and diffusion. This not only does not affect the propagation of sound but also plays a role in dust collection.

[0037] The quick-release component 300 includes cavities 303 formed at both ends of the inner cavity of the round cover plate 201. Each set of cavities 303 is slidably connected to a movable component 306, and a locking post 302 is installed on the movable component 306 for disassembling and assembling the round cover plate 201.

[0038] The dust-blocking and dust-collecting unit 200 also includes a movable cover 204 disposed on the cylinder 203. The movable cover 204 has multiple sets of through holes that connect to the dust cover 202. The through holes and the through holes on the dust cover 202 are connected and do not affect the propagation of sound.

[0039] Furthermore, both ends of the movable cover 204 are rotatably connected to a rotating handle 205, and both outer walls of the cylinder 203 are provided with magnetic layers 206, which are magnetically connected to the rotating handle 205. The rotating handle 205 is made of iron, and there is an attraction between the iron and the magnetic layer 206, which facilitates the fixing and loosening of the rotating handle 205, thus realizing the quick assembly and disassembly of the movable cover 204.

[0040] The quick-release component 300 also includes a limiting groove 307 formed on the movable component 306, and a telescopic rod 304 is fixedly connected between the limiting groove 307 and the inner wall of the cavity 303.

[0041] Furthermore, a spring 305 is fitted on the outer wall of the telescopic rod 304, and the spring 305 is located between the limiting groove 307 and the inner wall of the cavity 303; the elasticity of the spring 305 causes the moving part 306 and the locking post 302 to always move in the outward direction.

[0042] The round cover plate 201 has two sets of front slots 308 at its front end. The front slots 308 are connected to the cavity 303. A hand-held block 309 is slidably connected in the front slot 308, and the hand-held block 309 is fixedly connected to the moving part 306. The sliding of the hand-held block 309 in the front slot 308 can drive the moving part 306 and the locking post 302 to move. With the elasticity of the spring 305, the locking post 302 can move laterally, which facilitates its disassembly and assembly with the external installation structure and makes it easy to disassemble and assemble the round cover plate 201.

[0043] When in use, the acoustic sponge is placed inside the cylinder 203, the movable cover 204 is closed, and the magnetic connection between the rotating handle 205 and the magnetic layer 206 is established, thus installing the acoustic sponge inside. Dust in the air first passes through the dust cover 202 for dust prevention, and then passes through the acoustic sponge. The acoustic sponge adsorbs the micro dust in the air, improving the dust prevention effect of the round cover plate 201.

[0044] When the acoustic foam needs to be replaced, the handle 309 of the quick-release component 300 moves inward in the front slot 308. At this time, the spring 305 is in a compressed state, and the locking post 302 is disengaged from the mounting structure and stored in the cavity 303. The round cover plate 201 can then be removed without restriction. With the rotation of the handle 205, it is magnetically connected to the magnetic layer 206, which facilitates the replacement of the acoustic foam in the cylinder 203. During installation, the handle 309 is released, and the compressed spring 305 can automatically return to its original position, causing the moving part 306 and the locking post 302 to move toward one end of the mounting structure until the locking post 302 is installed, thus completing the fixing of the round cover plate 201.

[0045] Example 2

[0046] Reference Figures 1 to 3 This is the second embodiment of the present utility model. Based on the above embodiments, this embodiment further provides an automotive audio panel, including a dustproof mechanism; and an audio panel assembly 100, the audio panel assembly 100 including a panel body 101, a mounting sleeve 102 fixedly connected to the rear end of the panel body 101, and an audio body 103 installed in the mounting sleeve 102.

[0047] It should be noted that the panel body 101 serves as the interior panel of the car, and the audio body 103 is the car audio system.

[0048] The panel body 101 has an installation port 104 that connects to the round cover plate 201, and the inner walls on both sides of the installation port 104 have locking holes 105 for connecting with the locking post 302. The locking holes 105 can connect or disconnect from the locking post 302, realizing quick assembly and disassembly of the round cover plate 201 and the installation port 104, which facilitates the replacement of the acoustic sponge inside the cylinder 203. The dust cover 201 plays a role in blocking dust. When the micro-dust carried in the air flows through the internal channel of the acoustic sponge inside the cylinder 203, the micro-dust will be captured by the continuous and interconnected skeleton inside the acoustic sponge through mechanisms such as inertial collision, interception and diffusion, thus realizing the dust suction effect and improving the dustproof effect of the car audio panel.

[0049] In use, the round cover plate 201 of the dust-proof and dust-collecting unit 200 is installed on the panel body 101, and the hand block 309 moves in the opposite direction in the front slot 308. At this time, the spring 305 is in a compressed state, and the moving part 306 and the locking post 302 are located in the cavity 303. Then, the round cover plate 201 is installed in the mounting port 104. After the locking post 302 on the round cover plate 201 is aligned with the locking hole 105, the hand block 309 is released, and the compressed spring 305 automatically resets, causing the moving part 306 and the locking post 302 to move outward and connect with the locking hole 105, thus completing the fixing of the round cover plate 201.

[0050] The dust cover 201 serves to block dust. When dust carried in the air flows through the internal channels of the acoustic sponge inside the cylinder 203, the micro-dust is captured by the continuous and interconnected skeleton inside the acoustic sponge through mechanisms such as inertial collision, interception and diffusion, thus achieving a dust suction effect and improving the dustproof effect of the car audio panel. When replacing the acoustic sponge, the quick-release part 300 removes the round cover 201, and then the rotating handle 205 is rotated to disengage it from the magnetic layer 206 connected by the magnetic attraction. Once the movable cover 204 is no longer restricted, it can be removed, which facilitates the replacement of the acoustic sponge inside the cylinder 203 and prevents it from reaching a saturated state and affecting its dust suction effect.
