[0002] A search revealed Chinese patent application number 202120223698.9, which discloses a speaker grille for vehicles. Through structural design improvements, the ribs are almost invisible through the through-holes, simplifying the manufacturing process and enhancing the design and aesthetics of the speaker grille. The vehicle speaker grille covers a speaker installed inside a vehicle. The speaker grille includes: a body covering the speaker; a plurality of holes arranged in a straight line on the body; and straight ribs formed on the back of connecting portions linking adjacent holes.

[0003] Although the aforementioned patent simplifies the manufacturing process and enhances the design and aesthetics of the speaker grille by improving the structural design of the grille so that the ribs are almost invisible through the through holes, in actual use, dust tends to accumulate inside the grille after a long period of use, affecting the speaker's sound output. The aforementioned patent also makes it inconvenient to disassemble and clean the grille.

[0004] Therefore, it needs to be modified to facilitate the disassembly and cleaning of the grille cover, to avoid dust accumulating inside the grille after long-term use and causing blockage of the grille holes, and to improve the sound output of the speaker. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a vehicle speaker grille that facilitates disassembly and cleaning of the grille cover, avoids dust accumulation inside the grille after prolonged use which can clog the grille holes, and improves the sound output of the speaker. This solves the problem that dust easily accumulates inside the grille cover after prolonged use, affecting the sound output of the speaker and making it inconvenient to disassemble and clean the grille cover.

[0006] This utility model provides the following technical solution: a speaker grille for a vehicle, comprising a main body plate, a through-hole circular groove in the center of the main body plate, a first fixing ring fixedly connected inside the groove, a second fixing ring fixedly connected to the back of the first fixing ring, a grille cover on the inner side of the first fixing ring, and snap-fit ​​pieces fixedly connected to all four sides of the outer surface of the grille cover, the front of the snap-fit ​​pieces fitting against the back of the first fixing ring, openings corresponding to the snap-fit ​​pieces being formed around the front of the first fixing ring, and through-hole circular holes forming around the surface of the second fixing ring. Furthermore, a pressing rod is slidably connected inside the circular hole. The front end of the pressing rod is in contact with the back of the snap-fit ​​piece, and a movable ring is fixedly connected to the rear end of the pressing rod. A tension spring is sleeved behind the surface of the pressing rod. The front end of the tension spring is fixedly connected to the back of the second fixed ring, and the rear end of the tension spring is fixedly connected to the front of the movable ring. The surfaces of the first and second fixed rings are each provided with interconnected through holes that are staggered with the pressing rod. A movable rod is slidably connected inside the through holes. The rear end of the movable rod is fixedly connected to the front of the movable ring, and a pressing ring located outside the grille cover is fixedly connected to the front end of the movable rod.

[0007] The beneficial effects of this utility model are as follows:

[0008] 1. This utility model, by setting a main plate and mounting it on the interior panel of the speaker surface, creates a certain gap between the back of the moving ring and the speaker surface. When the holes on the grille surface become clogged with dust after prolonged use, affecting the sound output, pushing the moving bar upward releases the restriction on the pressing ring. By pressing the pressing ring backward, it moves backward, causing the moving rod to move backward, which in turn moves the moving ring backward, which in turn moves the pressing rod backward, causing the pressing rod to move backward. This causes the front end of the pressing rod to move away from the locking piece, at which point the locking piece is released. By rotating the grille clockwise... To remove the grille cover, align the snap-fit ​​tab with the opening slot. After cleaning, place the grille cover on the surface of the first fixing ring, align the snap-fit ​​tab with the opening slot, insert the grille cover into the first fixing ring, and press the pressing ring backward to rotate the grille cover counterclockwise. This will position the snap-fit ​​tab at the front end of the pressing rod. By releasing the pressing ring, the tension spring will contract, causing the moving ring and pressing rod to move forward and reset, thus fixing the snap-fit ​​tab and securing the grille cover. This facilitates the disassembly and cleaning of the grille cover, preventing dust from accumulating inside the grille after prolonged use and clogging the grille holes, thereby improving the speaker's sound output.

[0009] 2. This utility model uses a corresponding sliding strip and a rubber clip to limit the pressure ring by inserting the rubber clip between the pressing ring and the first fixing ring, thus preventing accidental contact with the pressing ring and ensuring the grid cover is securely fixed. When the grid cover needs to be disassembled, the sliding strip can be pushed upward to move the rubber clip away from the pressing ring, releasing the pressure ring's limitation and allowing it to move back and forth, facilitating the disassembly of the grid cover.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1 to 6As shown, the vehicle speaker grille of this embodiment includes a main body plate 1. A through-hole is formed in the center of the main body plate 1, and a first fixing ring 2 is fixedly connected inside the through-hole. A second fixing ring 3 is fixedly connected to the back of the first fixing ring 2. A grille cover 4 is provided inside the first fixing ring 2. A snap-fit ​​piece 5 is fixedly connected to all four sides of the outer surface of the grille cover 4. The front of the snap-fit ​​piece 5 fits against the back of the first fixing ring 2. Opening slots 6 corresponding to and cooperating with the snap-fit ​​pieces 5 are formed around all four sides of the front of the first fixing ring 2. A through-hole circular hole is formed around all four sides of the surface of the second fixing ring 3, and the inside of the circular hole can slide. A pressing rod 7 is connected, with its front end fitting against the back of the snap-fit ​​piece 5. A movable ring 8 is fixedly connected to the rear end of the pressing rod 7. A tension spring 9 is sleeved on the rear of the surface of the pressing rod 7. The front end of the tension spring 9 is fixedly connected to the back of the second fixed ring 3, and the rear end of the tension spring 9 is fixedly connected to the front of the movable ring 8. The surfaces of the first fixed ring 2 and the second fixed ring 3 are each provided with interconnected through holes that are staggered with the pressing rod 7. A movable rod 10 is slidably connected inside the through holes. The rear end of the movable rod 10 is fixedly connected to the front of the movable ring 8, and the front end of the movable rod 10 is fixedly connected to a pressing ring 11 located outside the grille cover 4.

[0018] refer to Figure 1 A movable strip 12 is slidably connected to the center of the front of the main body plate 1. A rubber clip 13 is fixedly connected to the bottom of the movable strip 12. The lower front of the rubber clip 13 is in contact with the back of the pressing ring 11, and the lower back of the rubber clip 13 is in contact with the front of the first fixing ring 2.

[0019] In this embodiment, by setting the corresponding cooperation between the moving strip 12 and the rubber clip 13, the rubber clip 13 is inserted between the pressing ring 11 and the first fixing ring 2, which has a limiting effect on the pressing ring 11 and avoids the situation where the grid cover 4 is not firmly fixed due to accidental contact with the pressing ring 11. When it is necessary to disassemble the grid cover 4, the moving strip 12 can be pushed upward to move the rubber clip 13 away from the pressing ring 11, thereby releasing the limiting effect of the pressing ring 11 and allowing it to move back and forth, which facilitates the disassembly of the grid cover 4.

[0020] refer to Figure 2 The second fixing ring 3 has a number of evenly distributed protective rings 14 fixedly connected inside, and a number of evenly distributed reinforcing ribs 15 fixedly connected between each protective ring 14.

[0021] In this embodiment, the protective ring 14 protects the speaker and prevents damage to the speaker from being touched during the removal of the grille cover 4 for cleaning. The reinforcing rib 15 improves the overall strength of the protective ring 14 and further enhances the protective effect.

[0022] refer to Figure 2The main body plate 1 has mounting buckles 16 fixedly connected to the top and bottom of the left and right sides of the back side. The mounting buckles 16 have threaded holes that pass through from front to back.

[0023] This embodiment, by providing a mounting clip 16 with threaded holes, allows for easy installation of the automotive accessory onto the surface of the vehicle speaker. It can be installed using either a snap-fit ​​or bolts, depending on the requirements.

[0024] refer to Figure 1 A leather panel 17 is fixedly connected to the front of the main body panel 1, and the surface of the leather panel 17 is provided with embossed patterns.

[0025] This embodiment improves the aesthetics of the automotive accessory by providing a leather plate 17 with embossed patterns, which also absorbs noise generated during speaker use, reduces low-frequency vibration, and further improves the speaker's sound output.

[0026] refer to Figure 1 The front of the grille cover 4 is fixedly connected with an anti-slip ring 18, and the surface of the anti-slip ring 18 is provided with anti-slip texture.

[0027] This embodiment increases the friction between the operator's palm and the grille cover 4 when disassembling and assembling the grille cover 4 by setting the anti-slip ring 18, increasing the force points and making it easier to rotate the grille cover 4.

[0028] This invention features a main plate 1 mounted on the interior panel of the speaker surface, creating a gap between the back of the moving ring 8 and the speaker surface. When dust clogs the holes on the grille cover 4 after prolonged use, affecting sound output, pushing the moving bar 12 upwards releases the restriction on the pressing ring 11. Pressing the pressing ring 11 backward causes it to move rearward, which in turn moves the moving rod 10. This movement, in turn, moves the moving ring 8, which in turn moves the pressing rod 7, moving its front end away from the locking piece 5. At this point, the locking piece 5 is released. The grille cover 4 can then be rotated clockwise. Align the snap-fit ​​piece 5 with the opening slot 6, and the grille cover 4 can be removed for cleaning. After cleaning, place the grille cover 4 on the surface of the first fixing ring 2, align the snap-fit ​​piece 5 with the opening slot 6, insert the grille cover 4 into the first fixing ring 2, press the pressing ring 11 backward to rotate the grille cover 4 counterclockwise, so that the snap-fit ​​piece 5 is located at the front end of the pressing rod 7. By releasing the pressing ring 11, the tension spring 9 retracts, driving the moving ring 8 and the pressing rod 7 to move forward and reset, fixing the snap-fit ​​piece 5 and fixing the grille cover 4. This facilitates the disassembly and cleaning of the grille cover 4, avoids the situation where dust easily accumulates inside the grille after long-term use, causing the grille holes to become blocked, and improves the sound output effect of the speaker.
