Detailed Implementation

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following is for reference. Figures 1-14 An audio system according to an embodiment of the present invention is described.

[0022] Reference Figure 2 and Figure 3 According to an embodiment of the first aspect of the present invention, an audio system 100 includes: a mounting bracket 1, an audio device 2, and a locking component 3.

[0023] The mounting bracket 1 has a receiving groove 11, which opens along one side in a first direction (e.g., direction e1 in the figure) to form an opening 12. An audio device 2 is received in the receiving groove 11, and the opening 12 is used for inserting or removing the audio device 2. A first locking structure 21 is provided on the side of the audio device 2 opposite to the opening 12. A locking assembly 3 is mounted on the side of the mounting bracket 1 opposite to the opening 12 and includes a drive mechanism 31. The drive mechanism 31 includes a motor 311 and a locking mechanism 32. The motor shaft 312 of the motor 311 is connected to the locking mechanism 32 to drive the locking mechanism 32 to switch between a locked state and an unlocked state. The locking mechanism 32 has a second locking structure 321. In the locked state, the second locking structure 321 engages with the first locking structure 21; in the unlocked state, the second locking structure 321 disengages from the first locking structure 21.

[0024] For example, the first direction could be the front-rear direction of vehicle 101.

[0025] For example, the audio system 100 is installed in vehicle 101, with the mounting bracket 1 fixedly connected to the interior of vehicle 101, and the opening 12 facing the rear of vehicle 101; as another example, the audio system 100 is installed in vehicle 101, with the mounting bracket 1 fixedly connected to the inside of the driver's side door of vehicle 101, and the opening 12 facing the right side of vehicle 101; as yet another example, the audio system 100 is installed in vehicle 101, with the mounting bracket 1 fixedly connected to the inside of the passenger side door of vehicle 101, and the opening 12 facing the left side of vehicle 101.

[0026] Users can insert the audio device 2 into the receiving slot 11 through the opening 12, or remove the audio device 2 from the receiving slot 11 through the opening 12 for carrying, so that the audio device 2 can play audio in different scenarios.

[0027] For example, the audio device 2 is provided with a handle so that the user can take the audio device 2 out of the receiving slot 11 from the opening 12, and it is also convenient for the user to carry the audio device 2.

[0028] For example, audio device 2 can have audio playback function, and audio device 2 can also have audio recording function.

[0029] For example, the audio system 100 is installed in the vehicle 101. The user can send an unlock or lock signal to the control system of the vehicle 101 via a mobile phone. After receiving the unlock or lock signal, the control system controls the motor 311 to rotate, so as to drive the first locking structure 21 to separate or lock the second locking structure 321.

[0030] For example, the audio system 100 includes a detector that controls the motor 311 to rotate to drive the first locking structure 21 to lock into engagement with the second locking structure 321 when the detector detects that the audio device 2 is accommodated in the receiving slot 11.

[0031] The locking component 3 is located on the side of the mounting bracket 1 away from the opening 12. Compared with the related technology where the locking components 3 are provided on both sides of the mounting bracket 1, the locking components 3 are concentrated in the position of the mounting bracket 1 away from the opening 12. The number of parts of the locking component 3 is reduced, and the manufacturing cost of the parts is reduced. In addition, the space occupied by the locking component 3 in the two directions of the mounting bracket 1 is reduced. When the audio system 100 is installed in the interior of the vehicle 101, it is beneficial to the setting and installation of other components in the interior.

[0032] Furthermore, in related technologies, the locking components 3 are located on both sides of the mounting bracket 1 (e.g., on both sides along direction e2 in the attached figure). The locking capabilities of the locking components 3 on both sides are not necessarily identical. When there is a difference in the locking force of the locking components 3 on both sides, the actual installation position of the audio device 2 will shift, resulting in a large gap between one side of the audio device 2 and the mounting bracket 1, which may lead to dust accumulation and an unsightly appearance. By placing the locking components 3 on the side of the mounting bracket 1 away from the open opening 12, the positional shift of the audio device 2 due to the difference in locking force between the locking components 3 on both sides can be avoided.

[0033] By having the motor 311 of the locking assembly 3 drive the locking mechanism 32 to switch between the locked and unlocked states, the structure of the locking assembly 3 is relatively simple and its assembly is easier.

[0034] According to the audio system 100 of the present invention, by placing the locking component 3 on the side of the mounting bracket 1 away from the open opening 12, compared with the related art in which the locking component 3 is provided on both sides of the mounting bracket 1, the number of parts of the locking component 3 is reduced, the manufacturing cost of the parts is reduced, and the space occupied by the locking component 3 in the two sides of the mounting bracket 1 is reduced; by having the motor 311 of the locking component 3 drive the locking mechanism 32 to switch between the locked state and the unlocked state, the structure of the locking component 3 is simpler and the assembly is simpler.

[0035] Reference Figures 12-14 According to some embodiments of the present invention, the locking assembly 3 includes a motor 311. By making the locking assembly 3 include only one motor 311, the number of parts of the locking assembly 3 can be reduced, the manufacturing cost of the audio system 100 can be reduced, and assembly can be simplified.

[0036] Reference Figure 3 According to some embodiments of the present invention, the first locking structure 21 is located at the middle of the audio device 2 along the second direction (e.g., direction e2 in the figure), where the first direction, the second direction, and the up-down direction intersect each other. By positioning the first locking structure 21 at the middle of the audio device 2 along the second direction, the limiting force of the second locking mechanism 32 on the first locking structure 21 is located at the middle of the audio device 2 in the second direction. This makes the limiting force of the second locking mechanism 32 on the first locking mechanism 32 more uniform in the second direction, avoiding a large gap between the audio device 2 and the mounting bracket 1 along the second direction, which could lead to dust accumulation or an unsightly appearance.

[0037] Reference Figure 5 , Figure 6 and Figure 10 According to some embodiments of the present invention, a first clearance opening 13 is formed on the side of the mounting bracket 1 away from the open opening 12. The first clearance opening 13 is used to avoid the second locking structure 321. The first locking structure 21 is a locking post 22, which extends along the second direction. The second locking structure 321 is formed as a locking hook 322. In the locked state, the locking hook 322 locks the locking post 22. The first direction, the second direction, and the up and down direction intersect each other.

[0038] By forming a first clearance opening 13 on the side of the mounting bracket 1 away from the open opening 12, and by making the first clearance opening 13 avoid the second locking structure 321, the second locking structure 321 can pass through the first clearance opening 13 and cooperate with the first locking structure 21, thereby preventing the mounting bracket 1 from interfering with the movement of the second locking structure 321.

[0039] For example, refer to Figure 11 The audio system 100 has a locking groove on the side facing away from the opening 12 in the first direction, and the locking pin 22 is accommodated in the locking groove and fixedly connected to the side wall of the locking groove.

[0040] By making the second locking structure 321 a hook 322 and the first locking structure 21 a pin 22, when switching from the unlocked state to the locked state, the second locking structure 321 can be rotated to make the hook 322 hook the pin 22; when switching from the locked state to the unlocked state, the second locking structure 321 can be rotated to separate the hook 322 from the pin 22, making the switching between the unlocked and locked states relatively convenient. In the locked state, the hook 322 can fully limit the pin 22 in the first direction, thereby limiting the audio device 2 and preventing the audio device 2 from falling off.

[0041] For example, when the audio system 100 is installed in the vehicle 101, the vehicle body vibrates when the vehicle 101 passes through a rough path. Since the locking hook 322 fully limits the locking pin 22 in the first direction when the vehicle is locked, the audio device 2 can be prevented from falling off due to vibration.

[0042] Reference Figure 14 According to some embodiments of the present invention, the drive mechanism 31 further includes a gear transmission mechanism 36, which is tractably connected between the motor shaft 312 and the locking mechanism 32. By including the gear transmission mechanism 36 in the drive mechanism 31, when the motor shaft 312 rotates, the gear transmits the rotation of the motor shaft 312 to the locking mechanism 32. The transmission of the gear is more precise, and the gear also functions as a speed reducer.

[0043] For example, the locking mechanism 32 switches between the unlocked and locked states by rotation, and the gear transmission mechanism 36 acts as a reducer, which can reduce the high speed of the motor 311 to a low speed output, so that the rotation range of the locking mechanism 32 is within the set range and the locking mechanism 32 has sufficient locking ability.

[0044] Reference Figures 5-9 According to some embodiments of the present invention, the locking mechanism 32 includes a fixed bracket 323 and a linkage mechanism 33. The driving mechanism 31 is mounted on the fixed bracket 323. The linkage mechanism 33 is a planar four-bar linkage 33 and includes a rocker arm 330, a first link 331 and a second link 332. The motor shaft 312 is drivenly connected to the rocker arm 330 to drive the rocker arm 330 to move. One end of the first link 331 is rotatably connected to the rocker arm 330, and the other end of the first link 331 is rotatably connected to the second link 332. The second link 332 is rotatably connected to the fixed bracket 323. The second locking structure 321 is provided on the second link 332. The rocker arm 330 is configured to drive the second locking structure 321 to lock with the first locking structure 21 when rotated in a third direction, and the rocker arm 330 is configured to drive the second locking structure 321 to separate from the first locking structure 21 when rotated in a fourth direction, the fourth direction being opposite to the third direction.

[0045] For example, the second locking structure 321 is integrally formed with the second connecting rod 332.

[0046] For example, the second locking structure 321 is a locking hook 322, and the first locking structure 21 is a locking pin 22. The locking hook 322 is formed on the side of the second link 332 close to the opening 12 along the first direction.

[0047] By making the linkage mechanism 33 a planar four-bar linkage mechanism 33, the rotation of the rocker arm 330 driven by the motor 311 can drive the first link 331 to swing and rotate. The first link 331 drives the second link 332 to rotate, thereby enabling the second locking structure 321 to engage or disengage with the second locking structure.

[0048] By rotatably connecting the second link 332 to the fixed bracket 323, the movement of the second link 332 can be a rotational motion. Compared with the related technology where the locking structure is set on the link that performs both swinging and rotational motions, the movement mode of the second link 332 can be simplified, the movement trajectory of the second link 332 can be made more accurate, and since one side of the second link 332 is rotatably connected to the fixed bracket 323, the second link 332 can withstand a larger torque, which can make the limiting force of the second locking structure 321 on the first locking structure 21 more sufficient.

[0049] Reference Figures 5-9 According to some embodiments of the present invention, the transmission connection point between the rocker arm 330 and the motor shaft 312 is the first connection point 341, the rotation connection point between the first connecting rod 331 and the rocker arm 330 is the second connection point 342, the rotation connection point between the first connecting rod 331 and the second connecting rod 332 is the third connection point 343, the rotation connection point between the second connecting rod 332 and the fixed bracket 323 is the fourth connection point 344, the line segment formed by connecting the first connection point 341 and the second connection point 342 is the first line segment 351, the line segment formed by connecting the second connection point 342 and the third connection point 343 is the second line segment 352, the line segment formed by connecting the first connection point 341 and the fourth connection point 344 is the third line segment 353, and the line segment formed by connecting the first connection point 341 and the third connection point 343 is the fourth line segment 354.

[0050] When the first line segment 351 and the second line segment 352 are collinear, the included angle between the first line segment 351 and the third line segment 353 is α1. When the locking mechanism 32 is in the locked state, the included angle between the first line segment 351 and the third line segment 353 is α2. The included angle between the first line segment 351 and the second line segment 352 is the first included angle θ. The first included angle θ is an obtuse angle and the vertex of the first included angle is located on the side of the fourth line segment 354 along the third direction, wherein α2 > α1.

[0051] When the first line segment 351 and the second line segment 352 are collinear, the planar four-bar linkage 33 forms a triangle, that is, the planar four-bar linkage 33 is in a "dead point" state. When the audio device 2 is subjected to vibration and the second link 332 is subjected to force, the first link 331 and the rocker arm 330 do not rotate. The planar four-bar linkage is in a self-locking state, which keeps the first locking structure 21 and the second locking structure 321 locked. This can prevent the audio device 2 from vibrating and causing the first locking structure 21 and the second locking structure 321 to separate, thereby preventing the audio device 2 from falling off.

[0052] By making the second included angle α2 greater than the first included angle α1, and with the vertex of the first included angle θ located on one side of the fourth line segment 354 along the third direction, the planar four-bar linkage 33 formed by the linkage mechanism 33 can rotate further in the locking direction relative to the "dead point" state when the locking mechanism 32 is in the locked state. When the audio device 2 is subjected to vibration disturbance, causing the second linkage 332 to be subjected to force, if the linkage mechanism 33 rotates in the unlocking direction, the linkage mechanism 33 needs to bypass the "dead point" state of the planar four-bar linkage 33. When the planar four-bar linkage 33 is in the "dead point" state, it is difficult to rotate the rocker arm 330 by applying force to the second linkage 332. This can prevent the linkage mechanism 33 from rotating in the unlocking direction, and more effectively prevent the audio device 2 from vibrating and causing the linkage mechanism 33 to rotate, separating the first locking structure 21 from the second locking structure 321, thereby causing the audio device 2 to fall off.

[0053] Reference Figures 5-9 According to some embodiments of the present invention, α2 and α1 satisfy 3°≤α2-α1≤5°. For example, the value of α2-α1 can be 3°, 3.5°, 4°, 4.5°, 5°, etc. By making the value of α2-α1 no greater than 3°, the locking mechanism 32 can rotate more fully in the locking direction around the "dead point" position when it is in the locked state, which can more effectively prevent the vibration of the audio device 2 from causing the linkage mechanism 33 to rotate, the first locking structure 21 and the second locking structure 321 to separate, thereby preventing the audio device 2 from falling off. By making the value of α2-α1 no less than 5°, the travel of the rocker arm 330 can be avoided when switching between the locked state and the unlocked state.

[0054] Reference Figures 5-6 , Figures 12-14 According to some embodiments of the present invention, the audio system 100 further includes a locking limit member 324, which is fixed to the fixed bracket 323. When the locking mechanism 32 is in the locked state, the locking limit member 324 abuts against the rocker arm 330 in the rotational circumferential direction of the rocker arm 330 and the locking limit member 324 is located on one side of the rocker arm 330 along the third direction.

[0055] By including a locking limiter 324 in the audio system 100 and positioning the locking limiter 324 on one side of the rocker arm 330 along the third direction, the locking limiter 324 can limit the rocker arm 330 when the locking mechanism 32 is in the locked state, preventing the rocker arm 330 from continuing to rotate along the third direction, causing the rocker arm 330 to drive the first link 331 and the second link 332 to rotate and separate the first locking structure 21 from the second locking structure 321.

[0056] Furthermore, when the drive mechanism 31 includes a gear transmission mechanism 36, the force that the gears can withstand is limited. When the locking mechanism 32 switches from the unlocked state to the locked state, the motor 311 drives the rocker arm 330 to rotate in a third direction. If the motor 311 is overloaded, causing the rocker arm 330 to continue rotating in the third direction, the rocker arm 330 will abut against the locking limit member 324. The abutment force between the rocker arm 330 and the locking limit member 324 balances the overloaded rotational force of the motor 311, reduces the force on the gear transmission mechanism 36, protects the gear transmission mechanism 36, and prevents damage to the teeth on the gears.

[0057] Reference Figure 14 According to some embodiments of the present invention, the drive mechanism 31 further includes a gear transmission mechanism 36, which is tractably connected between the motor shaft 312 and the locking mechanism 32. A portion of the motor shaft 312 is formed as a worm gear 313. The gear transmission mechanism 36 includes a plurality of gears that are tractively connected. The plurality of gears includes a first gear 361 and a second gear 362. The first gear 361 is meshed with the worm gear 313. The gear shaft of the second gear 362 is connected to the rocker arm 330 to drive the rocker arm 330 to rotate around the gear shaft of the second gear 362.

[0058] By including a gear transmission mechanism 36 in the drive mechanism 31, the gear converts the high speed of the motor shaft 312 into a low speed that drives the rocker arm 330 to rotate. This allows the motor 311 to reduce its speed through the gear transmission mechanism 36 to drive the rocker arm 330 to rotate, thereby locking or separating the first locking structure 21 from the second locking structure 321.

[0059] For example, the first gear 361 is a helical gear, which can make the meshing of the first gear 361 and the worm 313 more complete.

[0060] When the locking mechanism 32 switches from the unlocked state to the locked state, the rotation of the motor shaft 312 drives the worm gear 313 to rotate. The worm gear 313 meshes with the first gear 361, causing the first gear 361 to rotate. The first gear 361 drives the second gear 362 to rotate in a third direction. Since the gear shaft of the third gear is connected to the rocker arm 330, the rocker arm 330 is driven by the third gear to rotate in a third direction, thereby locking the first locking structure 21 and the second locking structure 321.

[0061] When the locking mechanism 32 switches from the locked state to the unlocked state, the rotation of the motor shaft 312 drives the worm gear 313 to rotate in the opposite direction. The worm gear 313 meshes with the first gear 361, thereby causing the first gear 361 to rotate in the opposite direction. The first gear 361 causes the second gear 362 to rotate in the fourth direction through transmission. Since the gear shaft of the third gear is connected to the rocker arm 330, the rocker arm 330 is driven by the third gear to rotate in the fourth direction, thereby unlocking the first locking structure 21 from the second locking structure 321.

[0062] Reference Figure 5 , Figure 6 and Figure 14 According to some embodiments of the present invention, the drive mechanism 31 further includes an electronic control module 37, which includes a circuit board 371 and a second connector 372. The second connector 372 is disposed on the circuit board 371. A second clearance opening 14 is formed on the side of the mounting bracket 1 away from the open opening 12. The second clearance opening 14 is used to avoid the second connector 372. The audio device 2 is provided with a first connector 23 on the side away from the open opening 12. The first connector 23 and the second connector 372 are detachably plugged in. The motor 311 is electrically connected to the circuit board 371.

[0063] By forming a second clearance opening 14 on the side of the mounting bracket 1 facing away from the open opening 12, the second connector 372 can pass through the second clearance opening 14, preventing the mounting bracket 1 from interfering with the insertion of the second connector 372 and the first connector 23. With the first connector 23 and the second connector 372 configured, when the audio device 2 is placed into the receiving slot 11 and installed in place, the first connector 23 and the second connector 372 are connected. This not only provides power to the audio device 2, but also allows the connection of the first connector 23 and the second connector 372 to confirm that the audio device 2 is installed correctly, facilitating the switching of the locking mechanism 32 from the unlocked state to the locked state.

[0064] Reference Figure 5 , Figure 6 and Figure 14According to some embodiments of the present invention, the electronic control module 37 is configured to control the rotation of the motor 311 when the first connector 23 and the second connector 372 are separated to connected, so that the motor 311 drives the locking mechanism 32 to switch from the unlocked state to the locked state; the electronic control module 37 also includes an unlock button 373, which is mounted on the mounting bracket 1 and close to the opening 12. The unlock button 373 is electrically connected to the circuit board 371. The electronic control module 37 is configured to control the rotation of the motor 311 when the unlock button 373 is pressed, so that the motor 311 drives the locking mechanism 32 to switch from the locked state to the unlocked state.

[0065] When the first connector 23 and the second connector 372 are separated and then plugged in, it means that the audio device 2 is placed in the receiving slot 11 and the audio device 2 is installed in place. At this time, the electronic control module 37 controls the motor 311 to rotate, so that the motor 311 drives the locking mechanism 32 to switch from the unlocked state to the locked state. This can limit the audio device 2 and prevent the audio device 2 from falling off when it is subjected to vibration.

[0066] By using the unlock button 373, the user can actively press the unlock button 373 to control the motor 311 to drive the locking mechanism 32 from the locked state to the unlocked state, thereby releasing the locking mechanism 32 from limiting the audio device 2, allowing the audio device 2 to be removed from the receiving slot 11. By placing the unlock button 373 closer to the opening 12, the user can press the unlock button 373 more conveniently. For example, the unlock button 373 is located on one side of the opening 12 along the second direction.

[0067] For example, after the second locking structure 321 is in the locked state, the electronic control module 37 generates a locking completion signal and transmits the signal to the audio device 2 through the first connector 23 and the second connector 372, so that the audio device 2 plays a specific prompt tone or voice such as "locked" to remind the user that the limit locking of the audio device 2 has been completed.

[0068] Reference Figures 12-14 According to some embodiments of the present invention, the locking assembly 3 includes a fixed bracket 323, on which the drive mechanism 31 and the electronic control module 37 are both mounted. By mounting the drive mechanism 31 and the electronic control module 37 on the fixed bracket 323, it is convenient to fix the drive mechanism 31 and the electronic control module 37, preventing them from displacing or falling off due to vibration; and it also facilitates the installation of the audio system 100.

[0069] For example, when installing the audio system 100, the drive mechanism 31 and the electronic control module 37 can be installed on the fixed bracket 323 to form a module, and then the fixed bracket 323 can be installed on the mounting bracket 1.

[0070] Reference Figure 1 According to a second aspect of the present invention, a vehicle 101 includes an audio system 100 according to a first aspect of the present invention.

[0071] For example, the audio system 100 includes an electronic control module 37, which is connected to the vehicle's power supply and communication. After the audio data of the vehicle 101 or the audio data via Bluetooth is transmitted to the electronic control module 37, it can be transmitted to the audio device 2 through the first connector 23 and the second connector 372, so that the audio device 2 can play audio.

[0072] For example, the audio system 100 includes an electronic control module 37, which is connected to the vehicle's power supply and communication. The user can send an unlock command to the vehicle 101 via Bluetooth using a mobile phone. After receiving the command, the electronic control module 37 controls the motor 311 to rotate, so that the motor 311 drives the locking mechanism 32 to switch from the locked state to the unlocked state.

[0073] According to an embodiment of the present invention, the vehicle 101 includes an audio system 100 according to a first aspect of the present invention, wherein the locking component 3 of the audio system 100 is disposed on the side of the mounting bracket 1 away from the opening 12, and the motor 311 of the locking component 3 drives the locking mechanism 32 to switch between a locked state and an unlocked state. The locking component 3 has fewer parts, is simpler to assemble, reduces the manufacturing cost of the parts, and reduces the space occupied by the locking component 3.
