Description
Technical Field
[0001] This utility model belongs to the technical field of automotive speaker cover plates, and specifically relates to an automotive speaker cover plate with a dustproof mesh. Background Technology
[0002] In the field of automotive speakers, traditional speaker covers typically only have a few sound pickup holes on the panel to transmit sound. While this structure can meet basic sound production needs, it has significant drawbacks: Firstly, it lacks sufficient dust protection, allowing external dust and debris to easily enter the speaker through the sound pickup holes. Long-term accumulation can lead to wear and tear on the speaker drivers, performance degradation, and even malfunctions, severely impacting the speaker's lifespan. Secondly, maintenance and cleaning are inconvenient. When dust removal or maintenance is required for the speaker or cover, the entire mounting plate often needs to be removed. Traditional covers are usually rigidly connected to automotive components or the speaker body via screws or clips. Disassembly for maintenance necessitates unscrewing all screws or separating the clips one by one. Tightening multiple bolts is cumbersome, and repeated separation of clips can easily cause breakage. The process is tedious, time-consuming, and labor-intensive, causing considerable inconvenience for users and maintenance. Utility Model Content
[0003] The purpose of this utility model is to provide a car speaker cover with a dustproof mesh, which has the advantages of good protection and convenient disassembly and maintenance.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a car speaker cover with a dustproof mesh, comprising a mounting plate, a stepped groove on the top of the mounting plate, a frame placed inside the stepped groove, a dustproof mesh assembled inside the frame, a baffle inside the stepped groove, L-shaped slots symmetrically formed inside the stepped groove, and locking blocks symmetrically assembled on the surface of the baffle to engage with the L-shaped slots. A recessed groove is symmetrically formed on the top of the mounting plate, and a limiting groove is symmetrically formed on the top of the baffle. A limiting mechanism that cooperates with the limiting groove is provided inside the recessed groove.
[0005] The above technical solution is adopted: This utility model, through the integrated design of the stepped groove positioning in the mounting plate, the frame support, and the baffle encapsulation, constructs a dedicated dustproof mesh barrier between the pickup hole and the speaker. The dustproof mesh can accurately intercept various suspended foreign objects in the air, while not affecting the penetration of sound waves, reducing the possibility of foreign objects intruding from structural gaps, and improving the dustproof effect. By innovatively adopting a combination of snap-fit and limiting mechanism for fixing, a quick disassembly and maintenance system is constructed. During maintenance, no tools are needed; the baffle can be quickly removed using only the finger limiting block. After the baffle is removed, the frame and dustproof mesh can be directly taken out from the stepped groove for cleaning or replacement without touching the mounting plate and fixing structure, reducing reliance on professional maintenance and improving user convenience.
[0006] The present invention is further configured such that a sound pickup hole is provided at the top of the baffle.
[0007] The above technical solution employs a sound pickup hole on the top of the baffle. Its core function is to provide a stable sound wave transmission channel for the speaker while ensuring the protective function of the dustproof net. On the one hand, it allows the sound generated by the speaker to pass smoothly through the baffle and be transmitted outward, avoiding the baffle from completely blocking the sound output and ensuring the normal sound output of the in-vehicle audio system. On the other hand, its position and size can be matched with the layout of the dustproof net, balancing the dual needs of dust protection and sound transmission without compromising the baffle's function of fixing and sealing the dustproof net, and avoiding sound quality loss due to structural design.
[0008] The present invention is further configured such that the limiting mechanism includes a limiting block hinged inside the inner groove, the limiting block being engaged with the limiting groove, and a supporting spring being engaged between the end of the limiting block away from the limiting groove and the inner groove.
[0009] The above technical solution involves the support spring pushing the limiting block in its natural state, causing it to engage with the limiting groove of the baffle. This, combined with the initial positioning of the L-shaped groove and the locking block, forms a double fixation, ensuring that the baffle will not loosen or fall off when the vehicle vibrates, thus guaranteeing structural stability. When the baffle needs to be removed, the end of the limiting block away from the limiting groove is compressed, causing it to disengage from the limiting groove and unlocking it. At this point, the baffle can be easily pushed apart along the L-shaped groove, allowing the operation to be completed without tools and providing a convenient channel for cleaning or replacing the dust screen.
[0010] The present invention is further provided that the top of the mounting plate has a plurality of mounting holes arranged at equal intervals.
[0011] The above technical solution allows the mounting plate to be securely connected to the corresponding speaker mounting position in the car interior using mounting holes and screws or other fasteners. This ensures that the cover plate does not shift or loosen in the vibration environment of the car, guaranteeing structural stability. The equidistant arrangement design makes it compatible with the common standardized installation spacing in car interiors. At the same time, the multiple mounting holes can distribute the fixing stress, avoid deformation of the cover plate caused by single-point force, and further improve assembly reliability.
[0012] The present invention is further provided that a sealing gasket groove is provided at the bottom of the mounting plate.
[0013] The above technical solution involves embedding a sealing gasket in the sealing gasket groove to fill the gap between the mounting plate and the car speaker mounting position, preventing dust and moisture from entering the speaker from the installation gap, thus enhancing the overall protection effect. The sealing gasket also acts as a buffer, reducing the transmission of vehicle vibration to the mounting plate and speaker, reducing structural noise, and protecting the stability of components.
[0014] The present invention is further configured such that both the mounting plate and the baffle are made of stainless steel.
[0015] The above technical solution utilizes stainless steel, which has high mechanical strength and can withstand vibrations during vehicle operation and pressure during interior assembly. This prevents deformation problems such as bending and breakage of mounting plates or baffles, ensures the dimensional stability of key structures such as stepped grooves and slots, guarantees the assembly accuracy of dustproof nets and baffles, and improves the service life of mounting plates and baffles.
[0016] In summary, this utility model has the following beneficial effects: 1. This utility model integrates a stepped groove positioning, frame support, and baffle encapsulation design within the mounting plate to create a dedicated dustproof mesh barrier between the pickup hole and the speaker. The dustproof mesh can accurately intercept various suspended foreign objects in the air without affecting sound wave penetration, reducing the possibility of foreign objects intruding through structural gaps and improving the dustproof effect. 2. This utility model innovatively adopts a combination of snap-fit and limiting mechanism to build a quick disassembly and maintenance system. During maintenance, no tools are needed. The baffle can be quickly removed by simply using the finger limiting block. After the baffle is removed, the frame and dustproof net can be directly taken out from the stepped groove for cleaning or replacement. There is no need to touch the mounting plate and fixing structure, reducing the reliance on professional maintenance and improving the convenience of use for users. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.
[0020] Example 1: refer to Figure 1 , Figure 2 and Figure 3A car speaker cover with a dustproof mesh 4 includes a mounting plate 1. The top of the mounting plate 1 has a stepped groove 2. A frame 3 is placed inside the stepped groove 2. The dustproof mesh 4 is installed inside the frame 3. A baffle 5 is set inside the stepped groove 2. Through the integrated design of the stepped groove 2 positioning, the frame 3 supporting and the baffle 5 encapsulating in the mounting plate 1, a dedicated dustproof mesh 4 barrier is built between the pickup hole 11 and the speaker. The dustproof mesh 4 can accurately intercept various suspended foreign objects in the air, while not affecting the penetration of sound waves, reducing the possibility of foreign objects intruding from structural gaps and improving the dustproof effect.
[0021] refer to Figure 1 and Figure 2 The top of the baffle 5 is provided with a sound pickup hole 11. The core function of the sound pickup hole 11 on the top of the baffle 5 is to provide a stable sound wave transmission channel for the speaker while ensuring the protective function of the dustproof net 4. On the one hand, it allows the sound generated by the speaker to pass smoothly through the baffle 5 and be transmitted outward, avoiding the baffle 5 from completely blocking the sound quality output and ensuring the normal sound output of the in-vehicle audio system. On the other hand, its position and size can be matched with the layout of the dustproof net 4. Without destroying the baffle 5's fixing and sealing function for the dustproof net 4, it balances the dual needs of dust protection and sound transmission, and avoids sound quality loss due to structural design.
[0022] refer to Figure 1 , Figure 2 and Figure 3 The top of the mounting plate 1 has multiple equally spaced mounting holes 12. By setting the mounting holes 12 and using screws and other fasteners, the mounting plate 1 can be firmly connected to the corresponding speaker mounting position in the car interior, ensuring that the cover does not shift or loosen in the vibration environment of the car driving, thus ensuring structural stability. The equally spaced design makes it compatible with the common standardized installation spacing in car interiors. At the same time, the setting of multiple mounting holes 12 can distribute the fixing stress, avoid the deformation of the cover caused by single point of force, and further improve the assembly reliability.
[0023] refer to Figure 3 The bottom of the mounting plate 1 is provided with a sealing gasket groove 13. By setting the sealing gasket groove 13, after the sealing gasket is embedded in the sealing gasket groove 13, the gap between the mounting plate 1 and the car speaker mounting position can be filled, preventing dust and moisture from entering the speaker from the installation gap, thus enhancing the overall protection effect. The sealing gasket also plays a buffering role, reducing the transmission of vehicle driving vibration to the mounting plate 1 and the speaker, reducing structural noise, and protecting the stability of the components.
[0024] refer to Figure 1 , Figure 2 and Figure 3Both mounting plate 1 and baffle 5 are made of stainless steel. Stainless steel has high mechanical strength and can withstand the vibration during vehicle operation and the pressure during interior assembly. This avoids bending, breakage and other deformation problems of mounting plate 1 or baffle 5, ensures the dimensional stability of key structures such as stepped groove 2 and card slot, ensures the assembly accuracy of dustproof net 4 and baffle 5, and improves the service life of mounting plate 1 and baffle 5.
[0025] Brief description of the usage process: A frame 3 with a dustproof net 4 is placed in the stepped groove 2 of the mounting plate 1. The baffle 5 is initially fixed to the L-shaped slot 6 by the locking block 7, and then locked by the limiting mechanism 10, the limiting block 101 and the support spring 102, forming a double protection of dustproof net 4 and baffle 5. Dustproof net 4 intercepts dust and debris, and baffle 5 encapsulates frame 3 and ensures sound wave transmission through the sound pickup hole 11, which not only prevents foreign objects from entering the speaker, but also does not affect the sound quality output.
[0026] Example 2: refer to Figure 1 and Figure 2 A car speaker cover with a dustproof net 4 includes a mounting plate 1. The top of the mounting plate 1 has a stepped groove 2, inside which a frame 3 is placed. The frame 3 is fitted with a dustproof net 4. A baffle 5 is installed inside the stepped groove 2. L-shaped slots 6 are symmetrically arranged inside the stepped groove 2. A locking block 7 that engages with the L-shaped slot 6 is symmetrically fitted on the surface of the baffle 5. A recessed groove 8 is symmetrically arranged on the top of the mounting plate 1. A limiting groove 9 is symmetrically arranged on the top of the baffle 5. A limiting mechanism 10 that cooperates with the limiting groove 9 is installed inside the recessed groove 8. By innovatively adopting a combination of locking and limiting mechanism 10, a quick disassembly and maintenance system is constructed. During maintenance, no tools are needed; the baffle 5 can be quickly removed using only the limiting block 101. After the baffle 5 is removed, the frame 3 and dustproof net 4 can be directly removed from the stepped groove 2 for cleaning or replacement without touching the mounting plate 1 and the fixing structure, reducing reliance on professional maintenance and improving user convenience.
[0027] refer to Figure 1 and Figure 2The limiting mechanism 10 includes a limiting block 101 hinged inside the inner groove 8. The limiting block 101 is engaged with the limiting groove 9. A support spring 102 is engaged between the end of the limiting block 101 away from the limiting groove 9 and the inner groove 8. By setting the limiting block 101 and the support spring 102, the support spring 102 pushes the limiting block 101 in its natural state, causing it to engage with the limiting groove 9 of the baffle 5. Combined with the initial positioning of the L-shaped slot and the locking block 7, a double fixation is formed to ensure that the baffle 5 will not loosen or fall off when the car vibrates, thus ensuring structural stability. When it is necessary to disassemble the baffle 5, the end of the limiting block 101 away from the limiting groove 9 compresses the support spring 102 to disengage it from the limiting groove 9 and release the lock. At this time, the baffle 5 can be easily pushed apart along the L-shaped slot 6. The operation can be completed without tools, providing a convenient channel for cleaning or replacing the dust screen 4.
[0028] Brief description of usage: During daily use, the limiting mechanism 10 and the snap-fit structure work together to ensure the stability of the baffle 5. When the dustproof net 4 needs to be cleaned, the limiting block 101 compresses the spring to release the lock, and the baffle 5 is separated along the L-shaped slot 6. The frame 3 and the dustproof net 4 can then be removed without disassembling the mounting plate 1, thus achieving quick disassembly and maintenance.
[0029] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
