[0062] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0063] The following description of the vehicle audio system of this utility model is based on the accompanying drawings.

[0064] like Figures 3 to 6 As shown, this utility model provides a car audio system, which includes a speaker assembly 10 and a decorative opening and closing mechanism. The speaker assembly 10 includes a support base 11 and a speaker 12. The support base 11 includes a cover 111, and the speaker 12 is disposed inside the cover 111. The decorative opening and closing mechanism includes a trim assembly 20 and an opening and closing drive assembly 30. The trim assembly 20 includes a plurality of protective trim pieces 21, which are arranged circumferentially around the cover 111 and are respectively rotatably disposed on the cover 111. The opening and closing drive assembly 30 is drivenly connected to the plurality of protective trim pieces 21 and is used to drive the plurality of protective trim pieces 21 to rotate between an open state and a closed state.

[0065] Specifically, the speaker 12 is located inside the housing 111 and is used to output sound signals. The housing 111 serves to protect the speaker 12. Multiple protective decorative plates 21 are arranged in a circumferential manner and surround the outer side of the housing 111. Each protective decorative plate 21 can swing relative to the housing 111. The opening and closing drive assembly 30 is used to drive the multiple protective decorative plates 21 to swing synchronously, so that the multiple protective decorative plates 21 can switch between an open state and a closed state relative to the housing 111. When the car audio system needs to be used, the multiple protective decorative plates 21 swing to the open state, so that the housing 111 is exposed and the interior of the housing 111 is exposed. The speaker 12 transmits sound to the outside world, improving the aesthetics of the car audio system. Furthermore, multiple protective panels 21 can be rotated to a closed state to house the cover 111. The protective panels 21 serve both decorative and protective functions for the cover 111, effectively preventing the cover 111 from being exposed to the outside and being damaged by external impacts. This ensures the sound quality and aesthetics of the car audio system and prevents dust and moisture from penetrating the interior of the cover 111 due to long-term exposure to the car's interior environment, thus extending the lifespan of the car audio system and enhancing the user experience.

[0066] In this embodiment of the utility model, the protective decorative piece 21 includes a decorative piece body 211 and an adapter rod 212. The decorative piece body 211 is disposed outside the cover 111, and the adapter rod 212 is disposed on the decorative piece body 211 and can be rotatably passed through the cover 111. A sliding groove 2121 is provided on the adapter rod 212. The opening and closing drive assembly 30 includes a sliding rod 31, a transmission seat 32 and an opening and closing drive member 33. The transmission seat 32 is disposed inside the cover 111, and the sliding rod 31 is disposed on the transmission seat 32 and can be slidably passed through the sliding groove 2121. The opening and closing drive member 33 is drivenly connected to the transmission seat 32 and is used to drive the sliding rod 31 to slide through the transmission seat 32.

[0067] like Figures 5 to 9 As shown, the decorative piece body 211 is located on the outside of the cover 111 to serve both decorative and protective functions. The adapter rod 212 is connected to the decorative piece body 211 and extends from the decorative piece body 211 into the cover 111. The opening and closing drive member 33 drives the transmission seat 32 to rise and fall, so that the transmission seat 32 drives the slide rod 31 to slide in the groove 2121 on the adapter rod 212. During the sliding process along the groove 2121, the adapter rod 212 rotates, causing the adapter rod 212 to drive the decorative piece body 211 relative to the cover 111. The number of sliding rods 31 corresponds to the number of protective trim pieces 21, and they pass through the sliding grooves 2121 one by one. This allows the opening and closing drive component 33 to synchronously drive multiple protective trim pieces 21 to swing between open and closed states by raising and lowering the drive transmission seat 32. This serves both to decorate the cover 111, improving the aesthetics of the car audio system, and to protect the cover 111 from direct impact damage and the intrusion of dust and moisture into the cover 111, thus improving structural stability. Furthermore, the trim piece bodies 211 are arranged in a petal or teardrop shape, and the multiple trim piece bodies 211 surrounding the outer periphery of the cover 111 further enhance the aesthetics.

[0068] In this embodiment of the utility model, the transmission seat 32 includes a connecting block 321 and a transmission assembly. The transmission assembly includes a transmission rod 322. One end of the transmission rod 322 is connected to the connecting block 321, and a slide rod 31 is disposed at the other end of the transmission rod 322. The opening and closing drive member 33 is drivenly connected to the connecting block 321 and is used to drive the connecting block 321 to rise and fall, so that the connecting block 321 drives the slide rod 31 to slide through the transmission rod 322.

[0069] like Figures 5 to 9As shown, the connecting block 321 is mounted on the opening and closing drive component 33. A transmission rod 322 is provided on the connecting block 321 corresponding to the position of each adapter rod 212, and a slide rod 31 is provided on each transmission rod 322. The slide rod 31 slides through the corresponding slide groove 2121. The opening and closing drive component 33 drives the connecting block 321 to rise and fall. The connecting block 321 drives multiple transmission rods 322 to rise and fall synchronously. Each transmission rod 322 drives the corresponding slide rod 31 to slide along the slide groove 2121 and drive the corresponding adapter rod 212 to swing. This realizes the synchronous driving of multiple decorative piece bodies 211 to swing between the open and closed states. The state switching of multiple decorative piece bodies 211 is smooth and the swing synchronization is high, which further improves the appearance and enhances the user experience.

[0070] Furthermore, the opening and closing drive component 33 can be configured as a lead screw motor in the prior art, with the drive shaft of the motor configured as a lead screw, and the connecting block 321 sleeved on the drive shaft of the motor and threadedly connected to the drive shaft of the motor, so that the opening and closing drive component 33 can drive the connecting block 321 to rise and fall to drive multiple adapter rods 212 to swing synchronously, with stable and reliable transmission and improved swing smoothness.

[0071] Those skilled in the art will understand that the opening and closing drive component 33 of this application is not limited to the above-mentioned structure of a lead screw motor. It can also be a telescopic electric cylinder, a telescopic air cylinder, or other structures that can drive the connecting block 321 to rise and fall, and all of these should be within the protection scope of this application.

[0072] In the embodiments of this utility model, such as Figures 5 to 8 As shown, each adapter rod 212 is provided with a clearance groove 1114 on the cover 111 for the adapter rod 212 to pass through. A pivot 2122 is provided on the adapter rod 212. The pivot 2122 is connected to the groove wall of the clearance groove 1114 so that the adapter rod 212 is hinged to the cover 111 through the pivot 2122. This allows the adapter rod 212 to drive the decorative piece body 211 to swing relative to the cover 111, making assembly convenient and quick.

[0073] In this embodiment of the utility model, the number of decorative piece components 20 is set to at least two, and at least two decorative piece components 20 are stacked and sleeved on the outer shell 111 in a direction from the inside to the outside. The number of transmission components is the same as the number of decorative piece components 20 and is spaced on the connecting block 321 in a direction from top to bottom.

[0074] like Figures 5 to 9As shown, at least two trim panel assemblies 20 are stacked and fitted around the housing 111 from the inside out. Each trim panel assembly 20 includes multiple protective trim panels 21 arranged circumferentially around the housing 111. The trim panel body 211 of each protective trim panel 21 is arranged in a petal or teardrop shape, which greatly improves the appearance of the car audio system and enhances the user experience. Furthermore, the number of transmission components is the same as the number of trim panel assemblies 20. At least two transmission components are spaced apart on the connecting block 321 in the vertical direction. Each transmission component includes multiple transmission rods 322 arranged circumferentially on the connecting block 321. Each transmission rod 322 is provided with a slide rod 31. The slide rod 31 passes through the corresponding slide groove 2121 to drive the adapter rod 212 and the trim panel body 211 to swing, which improves the swing synchronization and smoothness and further enhances the aesthetics of the state switching of the trim panel assembly 20.

[0075] In this embodiment of the utility model, the support base 11 further includes a support base plate 112, and the cover 111 is disposed on the support base plate 112. The car audio system also includes a mounting shell 40 and a lifting drive mechanism 50. The support base plate 112 is movably disposed inside the mounting shell 40, and the mounting shell 40 is provided with a lifting port 41 for the trim piece assembly 20 and the cover 111 to extend out of the mounting shell 40. The lifting drive mechanism 50 is drivenly connected to the support base plate 112 and is used to drive the support base plate 112 to lift.

[0076] like Figures 1 to 4 As shown, both the lifting drive mechanism 50 and the support base plate 112 are located within the mounting housing 40. The lifting drive mechanism 50 drives the support base plate 112 to rise or fall, causing the support base plate 112 to extend the trim assembly 20 and the cover 111 from the lifting port 41 to the outside of the mounting housing 40 or retract into the mounting housing 40. When the car audio system needs to be used, the lifting drive mechanism 50 drives the support base plate 112 to rise, causing the support base plate 112 to extend the trim assembly 20 and the cover 111 from the lifting port 41 to the outside of the mounting housing 40. Then, multiple protective trim pieces 21 swing to an open state, exposing the cover 111 to allow the speaker 12 to be exposed. The output sound can be transmitted to the outside world. The car audio system has an attractive appearance, which enhances the user experience. In addition, multiple protective trim pieces 21 can swing to a closed state to accommodate the cover 111 when the car audio system is not in use. Then, the lifting drive mechanism 50 drives the support base plate 112 to descend, so that the trim piece assembly 20 and the cover 111 retract from the lifting port 41 into the mounting shell 40. Both the mounting shell 40 and the protective trim pieces 21 can protect the cover 111, further preventing damage to the cover 111 from external impacts and preventing dust and moisture from entering the cover 111. This improves structural stability and extends the service life of the car audio system.

[0077] In this embodiment of the utility model, the car audio system also includes a protective opening and closing mechanism 60. The protective opening and closing mechanism 60 includes a baffle assembly 61 and a swing drive module 62. The baffle assembly 61 includes a plurality of swing baffles 611. The plurality of swing baffles 611 are arranged sequentially along the edge of the lifting port 41 and are respectively rotatably disposed on the mounting shell 40. The swing drive module 62 is drivenly connected to the plurality of swing baffles 611 and is used to drive the plurality of swing baffles 611 to swing between the open state and the closed state. When the plurality of swing baffles 611 are swung to the closed state, they block the lifting port 41.

[0078] like Figure 1 , Figures 10 to 12 As shown, the swivel baffle 611 is swivelly mounted on the mounting housing 40 and can swivel to a position that blocks the lifting port 41 or moves away from the lifting port 41. Multiple swivel baffles 611 are arranged sequentially along the edge of the lifting port 41. When the trim assembly 20 and the cover 111 are retracted into the mounting housing 40, the swivel drive module 62 drives the multiple swivel baffles 611 to swivel to the closed state, so that the multiple swivel baffles 611 all swivel to the position that blocks the lifting port 41 and cooperate to seal the lifting port 41. This not only prevents dust and moisture from entering the mounting housing 40, thus protecting the trim assembly 21 and the cover 111, but also improves the reliability of protection. Moreover, the swivel baffles 611 swivel from the open state to the closed state, which improves the aesthetics of the car audio system and enhances the user experience. Understandably, the swing drive module 62 drives multiple swing baffles 611 to the open state when the car audio system needs to be used, so that multiple swing baffles 611 are all swung to a position away from the lifting port 41, thereby opening the lifting port 41, which makes it easier for the support base plate 112 to drive the trim assembly 20 and the cover 111 to extend out of the lifting port 41. The structure is reasonably designed.

[0079] In this embodiment of the utility model, the swing drive module 62 includes a rotating wheel 621, a rotation drive assembly 622, and a plurality of swing push-pull rods 623. The rotating wheel 621 is rotatably disposed in the mounting shell 40 and is provided corresponding to the lifting port 41. The plurality of swing push-pull rods 623 are arranged circumferentially at intervals and are respectively hinged to the rotating wheel 621. The number of swing push-pull rods 623 is the same as the number of swing baffles 611, and the end of each swing push-pull rod 623 away from the rotating wheel 621 is hinged to the corresponding swing baffle 611. The rotation drive assembly 622 is drivenly connected to the rotating wheel 621 and is used to drive the rotating wheel 621 to rotate, so that the rotating wheel 621 drives the swing baffle 611 to swing through the swing push-pull rods 623.

[0080] like Figures 10 to 12As shown, the two ends of the swing push-pull rod 623 are respectively hinged to the rotating wheel 621 and the corresponding swing baffle 611. The rotating drive component 6222 drives the rotating wheel 621 to rotate. The rotating wheel 621 rotates to drive the swing push-pull rod 623 to swing towards a position close to or away from the lifting port 41. This causes the swing push-pull rod 623 to drive the corresponding swing baffle 611 to swing to a position that blocks the lifting port 41 or away from the lifting port 41. Multiple swing baffles 611 swing synchronously, which improves the aesthetics and smoothness of the swing.

[0081] Furthermore, the rotation drive assembly 622 includes a drive gear 6221 and a rotation drive member 6222. The rotation drive member 6222 can be a motor as in the prior art. The drive gear 6221 is sleeved on the drive shaft of the rotation drive member 6222. The rotating wheel 621 is a driven gear and meshes with the drive gear 6221. The rotation drive member 6222 drives the drive gear 6221 to rotate, so that the drive gear 6221 drives the rotating wheel 621 to rotate. The rotation of the rotating wheel 621 drives multiple swing baffles 611 to swing synchronously through multiple swing push-pull rods 623. The transmission is stable and reliable, and the swing smoothness is improved.

[0082] Those skilled in the art will understand that the rotation drive assembly 622 of this application is not limited to the above-described structural form. It may also include a pulley, a transmission belt, and a rotation drive component 6222. The rotation drive component 6222 may be a motor as in the prior art. The pulley is sleeved on the drive shaft of the rotation drive component 6222, and the transmission belt is wound around the pulley and the rotating wheel 621. The rotation drive component 6222 drives the pulley to rotate, and the pulley drives the rotating wheel 621 to rotate through the transmission belt. Other structural forms that can drive the rotating wheel 621 to rotate should also be within the protection scope of this application.

[0083] In this embodiment of the utility model, the swing baffle 611 has a swing edge 6111, a first fitting edge 6112, and a second fitting edge 6113. One end of the swing edge 6111 is hinged to the mounting shell 40, and the other end of the swing edge 6111 is hinged to the corresponding swing push-pull rod 623. The swing edge 6111 is adapted to the edge of the lifting port 41. The first fitting edge 6112 and the second fitting edge 6113 are respectively provided at both ends of the swing edge 6111. The distance between the first fitting edge 6112 and the second fitting edge 6113 is gradually reduced in the direction away from the swing edge 6111.

[0084] like Figures 10 to 12As shown, the two ends of the swing edge 6111 are hinged to the mounting housing 40 and the swing push-pull rod 623, respectively, so that the swing push-pull rod 623 can drive the swing baffle 611 to swing by pushing and pulling the swing edge 6111. The extension direction of the swing edge 6111 is adapted to the edge of the lifting port 41, so that when multiple swing baffles 611 swing to the closed state, the swing edge 6111 fits against the edge of the lifting port 41, thereby sealing the gap between the lifting port 41 and the swing edge 6111. The gap between them improves the reliability of protection; and the first fitting edge 6112 is connected to one end of the swing edge 6111, and the second fitting edge 6113 is connected to the other end of the swing edge 6111. The distance between the first fitting edge 6112 and the second fitting edge 6113 gradually decreases in the direction away from the swing edge 6111, so that multiple swing baffles 611 can be spliced ​​together to block the lifting port 41 and adapt to the lifting port 41 when they are swinging to the closed state. The structural design is reasonable.

[0085] Furthermore, both the first mating edge 6112 and the second mating edge 6113 are arc-shaped, and both protrude in the same direction, such as... Figures 10 to 12 As shown, in any two adjacent swing baffles 611, the first contact edge 6112 of one swing baffle 611 is used to contact the second contact edge 6113 of the other swing baffle 611, so that multiple swing baffles 611 can sequentially connect and seal the lifting port 41 when swinging to the closed state, which improves the sealing reliability and effectively prevents dust and moisture from entering the mounting shell 40. In addition, the first contact edge 6112 and the second contact edge 6113 are both arc-shaped to prevent swing interference and improve the swing smoothness of the swing baffle 611.

[0086] In this embodiment of the utility model, a limiting post 6211 is provided on the rotating wheel 621. The limiting post 6211 is used to abut against the swing push-pull rod 623 to limit the swing of the swing push-pull rod 623, such as... Figure 11 As shown, the first contact edge 6112 is in contact with the edge of the lifting port 41 when the swing push-pull rod 623 swings to abut against the limiting post 6211, so that the lifting port 41 is in an open state so that the trim assembly 20 and the cover 111 can extend out of the lifting port 41. The limiting post 6211 plays the role of limiting the swing stroke of the swing baffle 611.

[0087] Furthermore, such as Figure 12As shown, the swing drive module 62 also includes a fixed plate 624, which is connected to the mounting shell 40.
