[0032] For example, please refer to the attached Figure 1-7 A height-adjustable vehicle audio vibration isolation bracket includes a mounting plate 10 and an audio support plate 20 , wherein the mounting plate 10 and the audio support plate 20 are connected via a telescopic mechanism 30 ;

[0033] The telescopic mechanism 30 includes a plurality of telescopic rods 31 connected between the mounting plate 10 and the audio support plate 20 , and a limit knob 32 connected to the telescopic rods 31 .

[0034] For details, please refer to the attached Figure 1 and 2 The telescopic rod 31 includes a plurality of guide rails 311 connected to a surface of one side of the mounting plate 10, and a sliding rod 312 slidably connected to the guide rails 311;

[0035] The sliding rod 312 extends into the guide rail 311 and one end thereof is rotatably connected to a rotating rod 3121 , and one end of the rotating rod 3121 is rotatably connected to a sliding post 3122 ;

[0036] The sliding rod 312 extends into the guide rail 311 and has a fan-shaped groove 3123 at one end thereof. The fan-shaped groove 3123 is used to accommodate the rotating rod 3121.

[0037] It should be noted that, in this embodiment, the guide rail 311 is provided to provide a guide for the sliding of the sliding rod 312, so that the telescopic rod 31 can be stably extended and retracted.

[0038] Furthermore, the fan-shaped groove 3123 accommodates the rotating rod 3121 , and the groove body of the fan-shaped groove 3123 restricts the movement of the rod body of the rotating rod 3121 , so that the sliding column 3122 on the rotating rod 3121 can stably slide in the groove body of the sliding groove 3111 .

[0039] For details, please refer to the attached Figure 3 and 4 The guide rail 311 extends to one end of the guide rail 311 and is provided with a sliding groove 3111, and the sliding groove 3111 is used for sliding the sliding post 3122;

[0040] The chute 3111 is connected to a straight guide bar 3112 and a plurality of inclined guide bars 3113 connected to one side of the straight guide bar 3112. The plurality of inclined guide bars 3113 are arranged in sequence from top to bottom.

[0041] A plurality of vibration isolation pads 11 are connected to a surface of the mounting plate 10 on one side away from the sound support plate 20 , and the plurality of vibration isolation pads 11 are located at multiple corners of the mounting plate 10 ;

[0042] It should be noted that, in this embodiment, the slide post 3122 is guided to slide by the track formed between the groove body of the slide groove 3111 and the inclined guide bar 3113, so that the slide post 3122 can be inserted into the gap between the two inclined guide bars 3113 to maintain the position of the slide post 3122. In this way, the length of the telescopic rod 31 is maintained.

[0043] The slide post 3122 is guided to slide along the track formed between the groove body of the slide groove 3111 and the straight guide bar 3112, so that the slide post 3122 can slide down along the straight guide bar 3112, so that the user can readjust the position of the slide post 3122 and thus readjust the length of the telescopic rod 31.

[0044] Furthermore, the provision of the vibration isolation pad 11 provides a buffer for the vehicle audio system.

[0045] For details, please refer to the attached Figure 6 and 7 The noise reduction mechanism 40 includes a horizontal sound absorbing panel 41 connected to one side of the sound supporting panel 20 and symmetrically arranged, a plurality of telescopic columns 42 arranged in an array and slidably connected to the plate body of the horizontal sound absorbing panel 41, and a lifting sound absorbing panel 43 connected to one end of the plurality of telescopic columns 42 on the same side;

[0046] It should be noted that in this embodiment, the lifting and lowering of the sound absorbing panel 43 drives the multiple telescopic columns 42 on the panel body to rise and fall on the horizontal sound absorbing panel 41. The telescopic columns 42 contact the cavity of the car audio installation cavity, thereby providing support for the end of the vibration isolation bracket away from the audio support plate 20, improving the stability of the vibration isolation bracket installation, and the telescopic columns 42 with sound absorption effect fill the installation cavity to reduce noise.

[0047] The polyester fiber sound-absorbing sliding sleeve 422 absorbs noise, and the sliding of the polyester fiber sound-absorbing sliding sleeve 422 on the guide column 421 enables the telescopic column 42 to be extended and retracted, so that the telescopic column 42 can adapt to the cavity contour of the car audio installation cavity, thereby improving the applicability of the vibration isolation bracket;

[0048] The first spring 423 is provided to push the polyester fiber sound-absorbing sliding sleeve 422 away from the horizontal sound-absorbing panel 41 so that the polyester fiber sound-absorbing sliding sleeve 422 can be pressed tightly into the installation cavity. The second spring 424 is provided to push the lifting sound-absorbing panel 43 away from the horizontal sound-absorbing panel 41 so that the lifting sound-absorbing panel 43 can wait for the push of the translational sound-absorbing panel 45.

[0049] The guide post 421 is made of sound-absorbing material, such as polyester fiber, so that the guide post 421 cooperates with the polyester fiber sound-absorbing sleeve 422 to absorb sound.

[0050] For details, please refer to the attached Figure 6 and 7 The telescopic column 42 includes a guide column 421 inserted into the plate body of the horizontal sound-absorbing panel 41. The guide column 421 is sheathed with a polyester fiber sound-absorbing sleeve 422. One end of the guide column 421 extending into the polyester fiber sound-absorbing sleeve 422 is connected to a first spring 423. The other end of the first spring 423 is connected to the interior of the polyester fiber sound-absorbing sleeve 422. The guide column 421 is sheathed with a second spring 424 at one end away from the first spring 423. The second spring 424 is located between the lifting sound-absorbing panel 43 and the horizontal sound-absorbing panel 41.

[0051] The noise reduction mechanism 40 further includes an electric telescopic motor 44 connected to one side surface of the mounting plate 10, and a translational sound absorbing panel 45 connected to the actuator end of the telescopic motor 44. Both sides of the translational sound absorbing panel 45 and one side of the lifting sound absorbing panel 43 are provided with inclined surfaces.

[0052] Two vertical sound absorbing panels 46 are provided on one side of the translational sound absorbing panel 45. The vertical sound absorbing panels 46 are connected between the two horizontal sound absorbing panels 41. The two vertical sound absorbing panels 46 are symmetrically arranged on both sides of the speaker. A limit switch 47 is provided between the two horizontal sound absorbing panels 41. The limit switch 47 is connected to the plate body of the speaker support plate 20.

[0053] Furthermore, the electric telescopic motor 44 drives the translational sound absorbing panel 45. Since both sides of the translational sound absorbing panel 45 and one side of the lifting sound absorbing panel 43 are provided with inclined surfaces, the inclined surfaces of the chamfered surfaces push each other, so that when the translational sound absorbing panel 45 translates, it can push the lifting sound absorbing panel 43 to move up and down. In this way, the lifting sound absorbing panel 43 cooperates with the vertical sound absorbing panel 46 and the lifting sound absorbing panel 43 to form a sound insulation cavity, thereby reducing noise and vibration generated by the sound.

[0054] When the translation sound absorbing panel 45 touches the travel switch 47 , a sound insulation cavity is formed, and the electric telescopic motor 44 connected to the travel switch 47 stops pushing the translation sound absorbing panel 45 .

[0055] The specific operation mode of the present invention is as follows:

[0056] When installing the car audio system, the vibration isolation bracket is installed on the car body by passing the bolts through the mounting holes on the mounting plate 10. When in use, the audio support plate 20 is pulled to extend and retract the telescopic rod 31 between the audio support plate 20 and the mounting plate 10.

[0057] During the extension and retraction of the telescopic rod 31, the track formed between the groove body of the slide groove 3111 and the inclined guide bar 3113 guides the sliding of the slide post 3122, so that the slide post 3122 can be inserted into the gap between the two inclined guide bars 3113 to maintain the position of the slide post 3122. In this way, the length of the telescopic rod 31 is maintained.

[0058] The slide post 3122 is guided to slide along the track formed between the groove body of the slide groove 3111 and the straight guide bar 3112 so that the slide post 3122 can slide down along the straight guide bar 3112, so that the user can readjust the position of the slide post 3122 and then readjust the length of the telescopic rod 31.

[0059] The above description of the present invention is exemplified in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
