Description

[0001] This invention relates to the field of vehicle audio technology, specifically to an audio device suitable for new energy vehicle systems. Background Technology

[0002] With the global energy structure transformation and the technological innovation of the automotive industry, new energy vehicles (including pure electric vehicles and hybrid electric vehicles) have become the core direction of the automotive industry's development. Compared with traditional fuel vehicles, new energy vehicles show significant differences in power systems, vehicle architecture, and user needs. They are quieter, more intelligent, and have more flexible interior space layouts. This provides new opportunities for the upgrading and iteration of in-vehicle audio equipment, while also posing higher requirements. As one of the core configurations for enhancing the driving experience, the functional requirements of in-vehicle audio have been upgraded from basic sound playback to personalized sound effects, scenario adaptation, and intelligent linkage.

[0008] As a further aspect of the present invention: a miniature magnetic ring is connected to the upper end of the fitting base, and an iron ring is connected to the lower end of the audio device to cooperate with the miniature magnetic ring and limit the stability of the audio device.

[0009] As a further aspect of the present invention: the upper end of the repulsive magnetic ring is connected to the lower end of the stabilizer through a connecting column, and the outer wall of the lifting frame is provided with a lifting groove for providing space for the lifting of the stabilizer. The lifting groove is slidably connected with a lifting block for connecting to the stabilizer.

[0010] As a further aspect of the present invention: the bottom wall of the lifting chamber is equipped with a drive motor for driving the lifting frame to rise and fall, the output end of the drive motor is connected to a lead screw, and the outer wall of the lead screw is helically connected to the lifting frame. The upper end of the lead screw is provided with a flower-shaped groove, and the inner wall of the flower-shaped groove is slidably connected with a flower-shaped column. The lower end of the playback frame is rotatably connected to a support plate, and the lower end of the support plate is connected to the upper end of the fan-shaped inner frame. The lower end of the support plate is provided with a round hole, and the flower-shaped column passes through the round hole and connects to the lower end of the playback frame.

[0011] As a further aspect of the present invention: a telescopic groove is provided on the side of the fan-shaped outer frame near the fan-shaped inner frame, and a lifting moving block for driving the fan-shaped inner frame to rise and fall is slidably connected to the inner wall of the telescopic groove, and the lifting moving block is connected to the inner wall of the telescopic groove through a spring. A lifting moving groove for engaging with the lifting moving block is provided on the outer wall of the fan-shaped inner frame, and an inner recessed groove is provided on the outer wall of the fan-shaped inner frame, and the inner recessed groove is slidably connected to the outer wall of the outer plate.

[0012] As a further embodiment of the present invention: the inner wall of the external discharge hole is provided with a fixing slot and a sliding channel, and the sliding channel is connected to the sliding channel. The outer wall of the external discharge tube is connected with an inner sliding slider for sliding connection with the inner wall of the fixing slot and the sliding channel.

[0013] As a further aspect of the present invention: a fixing ring is connected to the inner wall of the external speaker hole on the side near the middle of the audio device, and a pull-back spring for pulling the external speaker tube back to its original position is connected to the side of the fixing ring near the external speaker tube. A connecting ring is connected to the side of the pull-back spring near the external speaker tube, and the connecting ring is rotatably connected to the external speaker tube.

[0014] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0015] 1. This invention dynamically adjusts the height of the lifting frame and combines Bluetooth with vehicle linkage function. It can synchronously optimize the sound source position according to the position of the people in the vehicle and the driving scenario to ensure uniform sound field coverage. The external speaker tube in the external speaker hole can be flexibly extended and retracted. When it is necessary to enhance the bass focus, it can extend outward to extend the sound path to meet the sound effect requirements of the closed space of the vehicle. The cooperation structure of the fan-shaped outer frame and the fan-shaped inner frame allows the outer plate to quickly lock and unlock the height of the playback frame. The sliding cooperation between the stabilizing frame and the lifting slide limit the lateral displacement of the playback frame and avoid the device shaking due to vehicle bumps. The mounting and locking structure of the outer plate further enhances the positional stability of the playback frame and prevents sound distortion or component damage.

[0016] 2. This invention increases the contact area between the device and the vehicle platform by fitting the base together. Combined with the magnetic attraction of the micro magnetic ring and the iron ring, it forms a dual fixation of "physical support + magnetic adsorption". This can effectively resist the external forces generated by the vehicle's start-stop and bumps during driving. By rotating the inner thread tube and spiraling up and down along the outer thread tube, the distance between the magnetic ring and the repulsive magnetic ring can be precisely adjusted, thereby controlling the magnitude of the magnetic repulsion force, reducing the energy consumption of the lifting mechanism, and fine-tuning the repulsion force according to the height requirements of the sound source, thus improving the stability of lifting.

[0017] 3. This invention precisely converts rotational motion into linear lifting motion through the helical connection between the lead screw and the lifting frame, ensuring direct and reliable power transmission. The spline connection between the flower-shaped groove and the flower-shaped column allows the lead screw to synchronously drive the playback frame to rotate, while the flower-shaped column can slide along the flower-shaped groove, cleverly solving the problem of motion interference between lifting and rotation. The interlocking design of the lifting connecting block and the lifting connecting groove ensures that the fan-shaped outer frame drives the fan-shaped inner frame to rise synchronously. Rotating the bearing plate can separate the two, and the outer plate provides stable support for the playback frame. The switching operation is simple and the fixation is reliable. The external speaker tube adjustment structure is flexible and the positioning is precise. The cooperation between the inner sliding slider, the translational through groove, and the fixing slot enables stepless adjustment and precise locking of the external speaker tube length.

[0018] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0032] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1

[0034] This invention provides an audio device suitable for new energy vehicle systems. During the daily driving of new energy vehicles, the positions of passengers may change with driving and riding needs, and different scenarios have different requirements for sound effects. At the same time, new energy vehicles are quieter, and traditional fixed sound source car audio systems are prone to uneven sound field coverage and muddy bass. Bumps during vehicle driving may also cause the audio components to shake, resulting in sound distortion.

[0035] Therefore, in order to effectively solve the above problems, this application proposes an audio device suitable for new energy vehicle in-vehicle systems, as shown in the attached drawings of the specification. Figure 1-11 As shown, the device includes an audio device 1. Inside the audio device 1, there is a playback frame 2 for dynamically adjusting the height of the sound source. The outer wall of the playback frame 2 has an external playback hole 21 for playing music. An external playback tube 22 for adjusting the length of the external playback hole 21 is slidably connected inside the external playback hole 21. Inside the audio device 1, there is a lifting frame 23 for pushing the height of the playback frame 2. The outer wall of the lifting frame 23 is connected to a stabilizing frame 24 for stabilizing the lifting of the playback frame 2. Inside the audio device 1, there is a lifting chamber. The side wall of the lifting chamber has a lifting groove for slidingly connecting with the outer wall of the stabilizing frame 24. The upper end of the stabilizing frame 24 is connected to a fan-shaped outer frame 27. The inner ring of the fan-shaped outer frame 27 is connected to a fan-shaped inner frame 25. The inner wall of the fan-shaped inner frame 25 is connected to an outer plate 26 for limiting the height of the playback frame 2. The outer wall of the playback frame 2 is slidably connected to the inner wall of the lifting chamber.

[0036] The upper part of the playback rack 2 is provided with a playback compartment, and the inside of the playback compartment is used to place the player. The inner wall of the playback compartment is spirally connected with a sealing cover, and Bluetooth is installed inside for linkage with the vehicle.

[0037] Among them, magnetic coil 32, miniature magnetic coil 33 and repulsive magnetic coil 36 are all magnets, and magnetic coil 32 and repulsive magnetic coil 36 are in a repulsive relationship.

[0038] The reciprocating lifting of the playback stand 2 can dynamically adjust the position of the sound source, thereby increasing the stereo effect of the music;

[0039] The lifting frame 23 inside the audio equipment 1 provides power support for the height adjustment of the playback rack 2. When music is played in the car, the audio equipment 1 is linked with the vehicle via Bluetooth to play music synchronously and dynamically adjust the height of the lifting frame 23. At the same time, the stabilizing frame 24 connected to the outer wall of the lifting frame 23 slides in the lifting groove on the side wall of the lifting compartment, thereby limiting the lateral displacement of the playback rack 2 and preventing swaying or tilting during the lifting process.

[0040] The external speaker hole 21 on the outer wall of the playback stand 2 is the channel for music playback. The external speaker tube 22, which is slidably connected inside, can change its exposed length by sliding along the axial direction of the external speaker hole 21. When it is necessary to enhance bass focus or reduce sound diffusion, the external speaker tube 22 can be extended outward to lengthen the sound propagation path.

[0041] The fan-shaped outer frame 27 and the fan-shaped inner frame 25 connected to the upper end of the stabilizer 24 form an angle adjustment and locking structure. The outer plate 26 connected inside the fan-shaped inner frame 25 can be fixed in height by fitting or snapping with the outer wall of the playback stand 2. After the lifting frame 23 adjusts the playback stand 2 to the target height, the fan-shaped outer frame 27 and the fan-shaped inner frame 25 are rotated relative to each other by rotating the support plate 53, thereby disengaging the fan-shaped inner frame 25 and the fan-shaped outer frame 27. At this time, the fan-shaped inner frame 25 and the fan-shaped outer frame 27 are disengaged. Then, the outer plate 26 is taken out from the inside of the fan-shaped inner frame 25 and placed on the upper end of the audio equipment 1, thereby limiting the position of the playback stand 2.

[0042] Example 2

[0043] The lower end of the audio device 1 is connected to a mounting base 11 for stabilizing the audio device 1. An external threaded tube 3 is installed in the middle of the upper end of the mounting base 11, and an internal threaded tube 31 is spirally connected to the outer wall of the external threaded tube 3. A magnetic ring 32 is connected to the upper end of the internal threaded tube 31.

[0044] The lower end of the audio equipment 1 is provided with an annular groove 35 for engaging with the internal threaded tube 31, and the lower end of the lifting frame 23 is connected with a repulsive magnetic ring 36 for cooperating with the magnetic ring 32 to push the stabilizer 24 to rise and fall on the outer wall of the lifting frame 23.

[0045] A miniature magnetic ring 33 is connected to the upper end of the base 11, and an iron ring 34 is connected to the lower end of the audio device 1 to cooperate with the miniature magnetic ring 33 to limit the stability of the audio device 1.

[0046] The upper end of the repulsive magnetic ring 36 is connected to the lower end of the stabilizer 24 via the connecting column 4. The outer wall of the lifting frame 23 is provided with a lifting groove 41 for providing space for the lifting of the stabilizer 24. The lifting groove 41 is slidably connected to a lifting block 42 for connecting with the stabilizer 24.

[0047] The magnetic force generated by the miniature magnetic ring 33 attracts the iron ring 34, making the audio device 1 fit tightly against the base 11, preventing the device from shifting or shaking when playing music or being touched by external force, and further enhancing the overall stability.

[0048] When the audio equipment 1 is placed on the base 11, the repulsive magnetic ring 36 and the magnetic ring 32 connected to the lower end of the lifting frame 23 are set with the same poles facing each other. The principle of mutual repulsion of like magnetic poles generates an upward repulsive force, thereby raising the height of the playback stand 2. When it is necessary to adjust the magnitude of the repulsive force between the magnetic ring 32 and the repulsive magnetic ring 36, the inner thread tube 31 can be rotated. The height of the magnetic ring 32 can be adjusted by rotating the inner thread tube 31 on the outer thread tube 3, thereby adjusting the distance between the magnetic ring 32 and the repulsive magnetic ring 36. At this time, the magnitude of the repulsive force between the magnetic ring 32 and the repulsive magnetic ring 36 can be adjusted.

[0049] When the lifting frame 23 drives the playback frame 2 to rise and fall, the stabilizing frame 24 slides along the lifting groove 41 via the lifting block 42, further limiting the lifting trajectory of the stabilizing frame 24.

[0050] Example 3

[0051] The bottom wall of the lifting chamber is equipped with a drive motor 5 for driving the lifting frame 23 to rise and fall. The output end of the drive motor 5 is connected to a lead screw 51, and the outer wall of the lead screw 51 is spirally connected to the lifting frame 23. The upper end of the lead screw 51 is provided with a flower-shaped groove, and the inner wall of the flower-shaped groove is slidably connected with a flower-shaped column 52. The lower end of the playback frame 2 is rotatably connected to a support plate 53, and the lower end of the support plate 53 is connected to the upper end of the fan-shaped inner frame 25. The lower end of the support plate 53 is provided with a round hole, and the flower-shaped column 52 passes through the round hole and is connected to the lower end of the playback frame 2.

[0052] A telescopic groove 6 is provided on the side of the fan-shaped outer frame 27 near the fan-shaped inner frame 25. A lifting moving block 61 for driving the fan-shaped inner frame 25 to rise and fall is slidably connected to the inner wall of the telescopic groove 6. The lifting moving block 61 is connected to the inner wall of the telescopic groove 6 by a spring. A lifting moving groove 62 for engaging with the lifting moving block 61 is provided on the outer wall of the fan-shaped inner frame 25. An inner recess 63 is provided on the outer wall of the fan-shaped inner frame 25. The inner recess 63 is slidably connected to the outer wall of the outer plate 26.

[0053] The inner wall of the external discharge hole 21 is provided with a fixing slot 7 and a sliding channel 71, and the sliding channel 71 is connected to the sliding channel 71. The outer wall of the external discharge tube 22 is connected with an inner sliding block 72 for sliding connection with the inner wall of the fixing slot 7 and the sliding channel 71.

[0054] A retaining ring 73 is connected to the inner wall of the external speaker 21 near the middle of the audio equipment 1. A pull-back spring 75 for pulling the external speaker 22 back to its original position is connected to the side of the retaining ring 73 near the external speaker tube 22. A connecting ring 74 is connected to the side of the pull-back spring 75 near the external speaker tube 22, and the connecting ring 74 is rotatably connected to the external speaker tube 22.

[0055] There are multiple fixed slots 7, and the translational through slot 71 connects the multiple fixed slots 7;

[0056] After the drive motor 5 starts, the lead screw 51 connected to its output end rotates synchronously. Since the outer wall of the lead screw 51 is screwed to the lifting frame 23, the rotational motion is converted into the linear lifting motion of the lifting frame 23 through the threaded connection, thereby pushing the playback frame 2 to slide up and down along the inner wall of the lifting chamber;

[0057] When the lead screw 51 rotates, the flower-shaped groove drives the flower-shaped column 52 to rotate synchronously through the spline engagement, thereby driving the playback frame 2 to rotate. At the same time, the flower-shaped column 52 can slide up and down along the flower-shaped groove without affecting the up and down movement of the playback frame 2 with the lifting frame 23. Meanwhile, the rotational connection design of the bearing plate 53 allows the playback frame 2 to rotate independently, avoiding interference with the movement of the fan-shaped inner frame 25.

[0058] When the lifting frame 23 is raised or lowered, it will simultaneously drive the fan-shaped outer frame 27 to be raised or lowered. At this time, the lifting moving block 61 connected inside the fan-shaped outer frame 27 is fitted into the inside of the lifting moving slot 62, and thus when the fan-shaped outer frame 27 is raised or lowered, it will simultaneously push the fan-shaped inner frame 25 and the playback frame 2 to be raised or lowered.

[0059] When it is necessary to keep the playback stand 2 stable on the top of the audio equipment 1, rotate the support plate 53. The rotation of the support plate 53 will drive the inner fan-shaped frame 25 to rotate. At this time, the rotation of the inner fan-shaped frame 25 will push the lifting connecting block 61 into the telescopic groove 6 until the inner fan-shaped frame 25 and the outer fan-shaped frame 27 are staggered. Then, take out the outer plate 26 and place it on the top of the audio equipment 1.

[0060] When it is necessary to adjust the length of the external speaker tube 22, push the external speaker tube 22 to drive the inner sliding slider 72 to slide along the translation channel 71 to the target position. Then rotate the external speaker tube 22 so that the inner sliding slider 72 is engaged in the corresponding fixed slot 7. The cooperation between the slot and the slider restricts the sliding of the external speaker tube 22, so as to achieve precise positioning of different lengths.

[0061] When the external speaker tube 22 extends outward, the return spring 75 is stretched and stores elastic potential energy. When the inward slider 72 is unlocked from the fixed slot 7, the elastic restoring force of the return spring 75 pulls the connecting ring 74, thereby causing the external speaker tube 22 to slide inward and reset along the external speaker hole 21.
