Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a locking mechanism, an audio installation assembly, an audio system and a vehicle. Background Art

[0002] With the development of vehicle technology, Bluetooth speakers can be installed in the cabin to meet the driver and passengers' needs for sound quality and portability.

[0003] In the related art, when a vehicle is driving on a bumpy road, the Bluetooth speaker in the speaker storage compartment will collide with the inner wall of the speaker storage compartment, which may easily damage the Bluetooth speaker. In order to stabilize the Bluetooth speaker, some solutions set a silicone strip on the inner wall of the speaker storage compartment and a magnet on the bottom wall, and use the friction of the silicone strip and the suction of the magnet to fix the speaker.

[0004] However, as the silicone strip ages and wears, the interference percentage between the Bluetooth speaker and the silicone strip deviates from the design value, making the Bluetooth speaker at risk of fixation failure. Summary of the invention

[0070] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0071] Figure 1 A schematic diagram of a vehicle structure provided in an embodiment of the present application, Figure 2 A schematic diagram of the location of the sound system in the cockpit provided in the embodiment of the present application. Figure 1 and Figure 2 The present application provides a vehicle 1000 , which may be a fuel vehicle, a new energy vehicle, or a hybrid vehicle. The vehicle 1000 includes a body 100 , drive wheels, and an audio system 300 .

[0072] Among them, the driving wheel can drive the vehicle body 100 to move, and the cockpit 101 in the vehicle body 100 is provided with an audio system 300. The audio system 300 provided in the present application can be stably connected to the interior trim panel 1010 of the cockpit 101 to prevent the audio system 300 and the interior trim panel 1010 from colliding with each other when the vehicle 1000 is driving on a bumpy road, causing damage to the audio system 300.

[0073] The following focuses on the structure of the audio system 300.

[0074] Figure 3 This is a schematic diagram of the exploded structure of the sound system provided in the embodiment of the present application. Figure 3 In some embodiments of the present application, the sound system 300 may include a mounting bracket 301, a sound box 302, and a locking mechanism 303. The sound box 302 is disposed in an inner cavity 3011 of the mounting bracket 301, and a locking cavity 3020 is disposed on a side wall of the sound box 302. The locking mechanism 303 has a first position and a second position.

[0075] In the first position, at least a portion of the locking mechanism 303 extends into the locking cavity 3020, preventing the speaker 302 from sliding along the inner wall of the mounting bracket 301, so that the speaker 302 is locked in the position inside the mounting bracket 301, thereby stably limiting the position of the speaker 302; in the second position, the locking mechanism 303 is separated from the locking cavity 3020, so that the speaker 302 loses the limitation of the locking mechanism 303. At this time, the speaker 302 can slide along the inner wall of the mounting bracket 301, and the user can take the speaker 302 out of the mounting bracket 301.

[0076] It should be noted that the number of the locking mechanisms 303 can be two, and the two locking mechanisms 303 are respectively connected to opposite sides of the mounting bracket 301. Accordingly, locking cavities 3020 corresponding to the locking mechanisms 303 are respectively provided on both sides of the speaker 302. In this way, the two locking mechanisms 303 can fix the speaker 302 from different directions, thereby ensuring the locking effect of the speaker 302.

[0077] Continue reading Figure 2 and Figure 3 It should also be noted that the position of the locking mechanism 303 can be such that a mounting hole 3012 is provided on the side wall of the mounting bracket 301, and the locking mechanism 303 is installed in the mounting hole 3012. In this way, the locking mechanism 303 is integrated into the side wall of the mounting bracket 301, which improves the compactness of the structure of the audio system 300, thereby facilitating the connection between the audio system 300 and the interior trim panel 1010.

[0078] In some embodiments of the present application, the audio system 300 may further include a position detection device, which is capable of detecting the position of the speaker 302 in the inner cavity 3011 , and the position detection device is electrically connected to the driving assembly 31 .

[0079] In this way, when the user places the speaker 302 into the inner cavity 3011 of the mounting bracket 301, the speaker 302 slides downward along the inner wall of the mounting bracket 301 until the position detection device detects that the speaker 302 reaches the preset position. At this time, the position detection device controls the movement of the driving component 31, so that the driving component 31 drives the locking mechanism 303 to move from the second position to the first position, thereby completing the automatic locking of the speaker 302.

[0080] It should be noted that the preset position may be a position where the speaker 302 completely falls into the inner cavity 3011 of the mounting bracket 301 and the bottom wall of the speaker 302 completely contacts the bottom wall of the mounting bracket 301. It may also be a position where the speaker 302 partially falls into the inner cavity 3011 of the mounting bracket 301 and the bottom wall of the speaker 302 partially contacts the bottom wall of the mounting bracket 301.

[0081] Figure 4 A schematic diagram of the position of the micro switch provided in the embodiment of the present application in the mounting bracket, Figure 5 for Figure 4 A schematic diagram of the enlarged structure at position A. Figure 3 , Figure 4 and Figure 5 In some embodiments of the present application, the position detection device may use a micro switch 304, which is disposed in the inner cavity 3011 of the mounting bracket 301. When the speaker 302 abuts against the micro switch 304, the micro switch 304 sends a start instruction to the driving component 31 to control the operating state of the driving component 31.

[0082] It is understandable that due to the small size, small contact spacing, short action stroke, small pressing force, and rapid on / off of the micro switch 304, some micro switches 304 have strong sealing properties and are also waterproof and dustproof. Therefore, the micro switch 304 can be conveniently integrated on the side wall or bottom wall of the mounting bracket 301, and can stably and quickly control the drive assembly 31 to start when the speaker 302 slides to the preset position, thereby completing the locking process in time.

[0083] See also Figure 5 In some embodiments of the present application, the micro switch 304 may include an action reed 3041 and a sliding portion 3042 , wherein the sliding portion 3042 is disposed on the action reed 3041 , and the sliding portion 3042 is slidably connected to the side wall of the speaker 302 .

[0084] In this way, during the process of taking out the speaker box 302, the sliding portion 3042 on the action reed 3041 can prevent the action reed 3041 from getting stuck with the side wall of the speaker box 302, which is conducive to the smooth removal of the speaker.

[0085] The structure of the sliding part 3042 can be various. For example, at least a part of the action reed 3041, for example, the end of the action reed 3041 can be bent toward the side away from the sound box 302 to form an arc surface, which is the sliding part 3042. The bottom of the arc surface can be slidably connected to the side wall of the sound box 302. For example, a ball bearing can be provided at the end of the action reed 3041 to further reduce the resistance of the action reed 3041 on the side wall of the sound box 302 in the direction of gravity when the sound box 302 is taken out.

[0086] Figure 6 This is a schematic diagram of the assembly structure of the sound system provided in the embodiment of the present application. Figure 3 and Figure 6 In some embodiments of the present application, the audio system 300 may further include a control button 305 , which is disposed on the mounting bracket 301 and is electrically connected to the driving component 31 .

[0087] In this way, when the speaker 302 needs to be unlocked, the user can control the drive component 31 to start through the control button 305, so that the drive component 31 can switch the locking mechanism 303 from the first position to the second position, and the locking mechanism 303 is separated from the locking cavity 3020, and the user can remove the speaker 302 from the inner cavity 3011 of the mounting bracket 301.

[0088] The specific forms of the above-mentioned control button 305 include various types: illustratively, the control button 305 can be a mechanical button; illustratively, the control button 305 can also be a virtual button on the central control screen of the cockpit 101 .

[0089] In some embodiments of the present application, the speaker 302 device may further include a reminder device, which is provided on a mechanical button and is electrically connected to the driving component 31. When the driving component 31 is running, the reminder device displays a first reminder message; when the driving component 31 is stationary, the reminder device displays a second reminder message.

[0090] In this way, the user can visually observe the operating state of the locking mechanism 303 through the reminder device integrated in the mechanical installation, so as to facilitate the determination of whether the speaker 302 has reached the preset position and locked. For example, when the reminder device displays the first reminder message, it means that the locking mechanism 303 is in the locking process; when the reminder device displays the second reminder message, it means that the locking mechanism 303 has been locked.

[0091] In some embodiments of the present application, the reminder device may include an indicator light, and the first reminder message is that the indicator light flashes quickly, and the second reminder message is that the indicator light stays on for a preset period of time and then goes out. The quick flashing of the indicator light here may be that the indicator light flashes 5 times in one second, and the preset duration may be 1 second or 2 seconds, etc.

[0092] In other embodiments, the first reminder information may be an indicator light showing red light, and the second reminder information may be an indicator light showing green light. The user can judge the locking progress of the locking mechanism 303 by the color of the indicator light.

[0093] In some embodiments of the present application, the reminder device may also be electrically connected to the position detection device, and the reminder device may also include a third reminder message and a fourth reminder message. When the position detection device detects that the locking mechanism 303 switches from the second position to the first position, that is, switches from the unlocked state to the locked state, the reminder device sends the above-mentioned first reminder message and second reminder message.

[0094] When the position detection device detects that the locking mechanism 303 switches from the first position to the second position, that is, switches from the locked state to the unlocked state, the reminder device can send out a third reminder message and a fourth reminder message in sequence, indicating that the locking mechanism 303 is in the unlocking process and the unlocking completion state respectively.

[0095] For example, the third reminder information may be an indicator light showing blue light, and the fourth reminder information may be an indicator light showing yellow light. The user can judge the unlocking progress of the locking mechanism 303 by the color of the indicator light.

[0096] In another embodiment, the locking progress or unlocking progress of the locking mechanism 303 can also be represented by the gradual change of the depth of the indicator light color. For example, the locking stage can be represented by red light, and from light red to dark red, it means that at least part of the limiter 32 in the locking mechanism 303 gradually extends into the locking cavity 3020 of the sound box 302; correspondingly, the unlocking stage can be represented by green light, and from light green to dark green, it means that the limiter 32 in the locking mechanism 303 gradually withdraws from the locking cavity 3020 of the sound box 302. In this way, it is convenient for the user to perceive the locking progress or unlocking progress of the locking mechanism 303 more accurately.

[0097] The above part describes the structure of the audio system 300 provided in the present application. The following part describes in detail the locking mechanism 303 in the audio system 300 in conjunction with the drawings in the specification.

[0098] The present invention provides a locking mechanism 303, which is used to connect the mounting bracket 301 and lock the to-be-locked member disposed in the inner cavity 3011 of the mounting bracket 301. It should be noted that the to-be-locked member may be a speaker 302, or may be a water cup or a portable storage box; the mounting bracket 301 may be disposed on the interior trim panel 1010 of the cabin 101, and the cabin 101 may be not only the cabin 101 in the vehicle 1000, but also the cabin 101 of transportation equipment such as a train, a ship, and an airplane.

[0099] In some other embodiments, the locking mechanism 303 may also be connected to the interior trim panel of the vehicle cabin, as long as the stopper 32 in the locking mechanism 303 can be extended into or out of the locking cavity 3020 located in the speaker 302. For ease of description, the connection between the locking mechanism 303 and the mounting bracket 301 is taken as an example for description.

[0100] Figure 7 This is a schematic diagram of the structure of the locking mechanism provided in an embodiment of the present application in the first position. Figure 8 A schematic diagram of the structure of the locking mechanism in the second position provided by the embodiment of the present application. Figure 3 , Figure 7 and Figure 8 In some embodiments of the present application, the locking mechanism 303 may include a limiter 32 and a drive assembly 31. The limiter 32 is connected to the mounting bracket 301, and the limiter 32 has a first position and a second position. The drive assembly 31 is connected to the limiter 32, and the limiter 32 is driven to switch between the first position and the second position to lock and unlock the speaker 302.

[0101] The locking mechanism 303 provided in the embodiment of the present application can control the locking and unlocking of the speaker 302 by changing the relative position of the limiting member 32 and the inner cavity 3011. When the speaker 302 is placed in the inner cavity 3011, the driving component 31 can control at least a portion of the limiting member 32 to extend into the inner cavity 3011, so that the limiting member 32 abuts against the locking cavity 3020 of the speaker 302, preventing the speaker 302 from sliding along the inner wall of the mounting bracket 301, thereby stably limiting the speaker 302; when the driving component 31 controls the limiting member 32 to move toward the side away from the inner cavity 3011, so that the limiting member 32 separates from the locking cavity 3020, the speaker 302 loses the limit of the locking mechanism 303, and at this time, the speaker 302 can slide along the inner wall of the mounting bracket 301, and the user can take the speaker 302 out of the mounting bracket 301.

Fig.10 for Figure 7 Schematic diagram of the cross-section structure at position B, Fig.11 for Figure 8 The enlarged structural diagram at position C, combined with reference Figure 3 , Fig. 9 , Fig.10 and Fig.11In some embodiments of the present application, the locking mechanism 303 may include an active rod 321, a connecting rod 322, and a driven rod 323. The active rod 321 is connected to the driving assembly 31, the driving assembly 31 drives the active rod 321 to rotate relative to the mounting bracket 301, and one end of the connecting rod 322 is rotatably connected to the active rod 321. One end of the driven rod 323 is rotatably connected to the other end of the connecting rod 322, and the other end of the driven rod 323 is rotatably connected to the mounting bracket 301. The connecting rod 322 forms a limiter 32, and the side of the connecting rod 322 facing the speaker 302 forms a first abutment portion 3220, and the first abutment portion 3220 can abut against the speaker 302 to lock the speaker 302.

[0103] It should be noted that when the speaker 302 is placed in the inner cavity 3011 of the mounting bracket 301, the speaker 302 can slide toward the bottom of the inner cavity 3011 under the action of its own gravity or the pressure applied by the user. However, due to the influence of factors such as the placement angle of the speaker 302 or the friction between the speaker 302 and the inner wall of the mounting bracket 301, the bottom wall of the speaker 302 usually cannot be in smooth contact with the bottom wall of the mounting bracket 301, but is in an incomplete contact or suspended state, which is not conducive to the stable locking of the locking mechanism 303.

[0104] In order to further improve the locking effect of the locking mechanism 303, the present application combines an active rod 321, a connecting rod 322, a driven rod 323 and a mounting bracket 301 to form a locking mechanism 303, and uses the connecting rod 322 as a limiter 32 in the locking mechanism 303. When the driving component 31 is running, the active rod 321 can be driven to rotate. After the active rod 321 rotates, it can drive the connecting rod 322 and the driven rod 323 to rotate in turn.

[0105] It can be understood that since the pushing distance of the connecting rod 322 during movement is larger than the pushing distance of the driven rod 323 during rotation, when the connecting rod 322 is used as a limit member 32, the speaker 302 can be further pushed toward the bottom wall of the mounting bracket 301 on the basis of the abutment between the first abutment portion 3220 and the locking cavity 3020, so that the bottom wall of the speaker 302 and the bottom wall of the mounting bracket 301 can be smoothly fitted, thereby effectively improving the locking effect of the locking mechanism 303.

[0106] In order to ensure that the first abutting portion 3220 on the connecting rod 322 can abut against and push the speaker 302 to move, it is necessary to perform derivative deformation on the basis of the conventional four-bar mechanism, specifically:

[0107] Fig.12 The exploded structural diagram of the locking mechanism provided in the embodiment of the present application is shown in FIG. Fig. 9 , Fig.11 and Fig.12In some embodiments of the present application, the connecting rod 322 may include a connecting section 3221 and an extending section 3222. The connecting rod 322 and the active rod 321 form a first rotation pair 3240 at the connecting position. The connecting rod 322 and the driven rod 323 form a second rotation pair 3250 at the connecting position. The connecting rod 322 forms a connecting section 3221 at a portion located between the first rotation pair 3240 and the second rotation pair 3250. The extending section 3222 is connected to the connecting section 3221, and the first abutting portion 3220 is formed at one end of the extending section 3222 away from the connecting section 3221.

[0108] It should be noted that the connecting rod 322 and the active rod 321 may be rotationally connected via the first rotating shaft 324 , and the connecting rod 322 and the driven rod 323 may be rotationally connected via the second rotating shaft 325 .

[0109] In this way, when the active rod 321 rotates to drive the connecting rod 322 to rotate, the connecting rod 322 can abut against the locking cavity 3020 by means of the extension section 3222, and push the speaker 302 to move up and down in the mounting bracket 301. The specific length of the extension section 3222 can be set according to the gap between the bottom wall of the speaker 302 and the bottom wall of the mounting bracket 301. If the gap is large, the length of the extension section 3222 should be long, so that the pushing distance of the extension section 3222 is large; conversely, if the gap is small, the length of the extension section 3222 should be short, so that the pushing distance of the extension section 3222 is short.

[0110] It should be noted that the specific structure of the extension section 3222 can be a straight rod or a curved rod. When the extension section 3222 is a curved rod, the equivalent length of the extension section 3222 is the straight-line distance from the second rotational pair 3250 to the first abutting portion 3220. Similarly, the specific structure of the connection section 3221 can be a straight rod or a curved rod. When the connection section 3221 is a curved rod, the equivalent length of the connection section 3221 is the straight-line distance from the first rotational pair 3240 to the second rotational pair 3250.

[0111] Continue reading Figure 3 and Fig. 9 In some embodiments of the present application, the above-mentioned stopper 32 may be formed by the driven rod 323, and the second abutting portion 3230 may be formed on the side of the driven rod 323 facing the speaker 302. In this way, when the second abutting portion 3230 extends into the locking cavity 3020, the second abutting portion 3230 may lock the speaker 302; when the second abutting portion 3230 is separated from the locking cavity 3020, the second abutting portion 3230 may unlock the speaker 302.

[0112] It can be understood that the present application can lock the speaker 302 by the first abutment portion 3220 of the connecting rod 322, can lock the speaker 302 by the second abutment portion 3230 of the driven rod 323, or can simultaneously use the first abutment portion 3220 and the second abutment portion 3230 to lock the speaker 302. At this time, the second abutment portion 3230 can assist the first abutment portion 3220 to limit the speaker 302, thereby further improving the locking effect of the speaker 302.

[0113] Continue reading Figure 3 and Fig. 9 In some embodiments of the present application, a first elastic member 3223 is provided on the first abutting portion 3220 and / or the second abutting portion 3230. In this way, the elastic force of the first elastic member 3223 can be used to buffer the collision between the locking mechanism 303 and the speaker 302, thereby preventing the locking mechanism 303 from causing scratches or dents on the side wall of the speaker 302 during the locking process.

[0114] It should be noted that the first elastic member 3223 here can be made of flexible materials such as a rubber pad, a sponge pad or an elastic fiber pad.

[0115] Continue reading Fig. 9 and Fig.12 In some embodiments of the present application, the active rod 321 and the mounting bracket 301 form a third rotation pair 3260 at the connection position, the driven rod 323 and the mounting bracket 301 form a fourth rotation pair 3270 at the connection position, and the mounting bracket 301 forms a fixed rod 328 of the locking mechanism 303 at the part located between the third rotation pair 3260 and the fourth rotation pair 3270.

[0116] It should be noted that the mounting bracket 301 and the active rod 321 may be rotatably connected via the third rotating shaft 326 , and the mounting bracket 301 and the driven rod 323 may be rotatably connected via the third rotating shaft 326 .

[0117] The following section will analyze the rod length factors of the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328 in the locking mechanism 303, and elaborate on the influence of different rod lengths on the locking effect.

[0118] In some embodiments of the present application, the sum of the length of the shortest rod and the length of the longest rod among the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328 is greater than the sum of the lengths of the other two rods. The shortest rod is any one of the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328, and the longest rod is any other one of the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328.

[0119] It should be noted that no matter how the specific structures of the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328 change, when performing the above calculations, the length of the active rod 321 is the straight-line distance between the first rotating pair 3240 and the third rotating pair 3260; the length of the connecting rod 322 is the straight-line distance between the first rotating pair 3240 and the third rotating pair 3260, and the extension section 3222 is used as a derived structure, and the length of the extension section 3222 is not considered at this time; the length of the driven rod 323 is the straight-line distance between the second rotating pair 3250 and the fourth rotating pair 3270; the length of the fixed rod 328 is the straight-line distance between the third rotating pair 3260 and the fourth rotating pair 3270.

[0120] It can be understood that when the sum of the length of the shortest rod and the length of the longest rod is greater than the sum of the lengths of the other two rods, the locking mechanism 303 does not meet the rod length condition, and the active rod 321 and the driven rod 323 cannot be used as cranks. At this time, no matter which rod in the locking mechanism 303 is used as the shortest rod, the locking mechanism 303 is a double rocker mechanism, and the active rod 321 and the driven rod 323 can reciprocate within a certain angle range. Since the double rocker mechanism has the characteristic of torque amplification, different degrees of torque amplification can be achieved by changing the length and relative angle of the active rod 321 and the driven rod 323, so that the locking force applied by the locking mechanism 303 on the speaker 302 is adjustable, so as to adapt to speakers 302 of different weights.

[0121] It should be noted that when the driving assembly 31 adopts the motor 311, the motor 311 needs to be controlled to rotate forward or reverse within a certain range, and drive the active rod 321 to rotate forward or reverse around the third rotating shaft 326. When the active rod 321 rotates forward, the active rod 321 drives the connecting rod 322 and the driven rod 323 to swing toward the direction close to the sound box 302, so that the first abutting portion 3220 and the second abutting portion 3230 abut against the locking cavity 3020, and the sound box 302 is locked; when the active rod 321 reverses, the active rod 321 drives the connecting rod 322 and the driven rod 323 to swing toward the direction away from the sound box 302, so that the first abutting portion 3220 and the second abutting portion 3230 are separated from the locking cavity 3020, and the sound box 302 is unlocked.

[0122] In some embodiments of the present application, among the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328, the sum of the length of the shortest rod and the length of the longest rod is less than or equal to the sum of the lengths of the other two rods, and the active rod 321 is the shortest rod. The shortest rod is any one of the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328, and the longest rod is any other one of the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328.

[0123] In this way, the locking mechanism 303 meets the rod length condition. The locking mechanism 303 is a crank rocker mechanism. The active member acts as a crank to move a full circle around the third rotating shaft 326, and the driven member swings back and forth around the fourth rotating shaft 327 within a certain angle range. The motor 311 can complete the locking and unlocking of the speaker 302 without forward and reverse rotation, and there is no need to limit the rotation angle range of the motor 311. The motor 311 can drive the active rod 321 to rotate in one direction, and the active rod 321 can drive the driven member and the connecting rod 322 to swing back and forth to complete the locking or unlocking of the speaker 302.

[0124] In some embodiments of the present application, among the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328, the sum of the length of the shortest rod and the length of the longest rod is less than or equal to the sum of the lengths of the other two rods, and the fixed rod 328 is the shortest rod. The shortest rod is any one of the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328, and the longest rod is any other one of the active rod 321, the connecting rod 322, the driven rod 323 and the fixed rod 328.

[0125] In this way, the locking mechanism 303 meets the rod length condition, and the locking mechanism 303 is a double crank mechanism, the active member as the active crank performs a full circle motion around the third rotating shaft 326, and the driven member as the driven crank performs a full circle motion around the fourth rotating shaft 327. When the length of the active crank is smaller than the length of the driven crank, the locking mechanism 303 can have a quick return characteristic, and the speed of the driven crank in the locking stroke is faster than the speed in the unlocking stroke, so that the locking process of the locking mechanism 303 is faster.

[0126] The following section will take the locking mechanism 303 as a double rocker mechanism as an example to further explain the locking mechanism 303 of the present application.

[0127] Continue reading Figure 7 In some embodiments of the present application, the colinear position of the active rod 321 and the connecting rod 322 is the first position of the locking mechanism 303.

[0128] It can be understood that when the active rod 321 rotates to be collinear with the connecting rod 322, and the position at this time is the first position of the locking mechanism 303, i.e., the locking position, the transmission angle and the rotational torque of the force applied by the speaker 302 to the connecting rod 322 along the collinear direction are zero. At this time, no relative rotation will occur between the connecting rod 322 and the active rod 321, and the locking mechanism 303 has good rigidity along the collinear direction, so that the locking effect of the locking mechanism 303 is better.

[0129] The above-mentioned collinear direction may include various situations:

[0130] For example, in some embodiments of the present application, the active member points to the connecting rod 322, and the colinear direction of the active member and the driven member faces the bottom wall of the inner cavity 3011. In this way, the active rod 321 and the connecting rod 322 can jointly form an oblique downward force, which can press the speaker 302 against the bottom wall of the inner cavity 3011, and has a good limiting effect on the speaker 302 in both the up and down directions and the left and right directions.

[0131] For example, in some embodiments of the present application, the active member points to the connecting rod 322, and the collinear direction is parallel to the bottom wall of the inner cavity 3011. In this way, the active rod 321 and the connecting rod 322 can jointly form a horizontal force, and the locking mechanism 303 has a large rigidity in the horizontal direction, so that the left and right directions of the speaker 302 have a good limiting effect.

[0132] Continue reading Fig. 9 In some embodiments of the present application, a stop portion 3210 is provided on one side of the active rod 321 facing the driven rod 323 , wherein when the connecting rod 322 and the active rod 321 are colinear, the stop portion 3210 abuts against the driven rod 323 .

[0133] It can be understood that the stop portion 3210 can fill the gap between the active rod 321 and the driven rod 323, so that when the locking mechanism 303 is in the locked state, the relative position between the active rod 321 and the driven rod 323 remains in a more stable state, and then the connecting rod 322 also has a more stable locking force under the limiting action of the active rod 321 and the driven rod 323, thereby further improving the locking effect of the locking mechanism 303.

[0134] Continue reading Fig. 9 In some embodiments of the present application, the driven rod 323 is arched toward a side away from the active rod 321 to form an avoidance cavity 3231 .

[0135] In this way, on the one hand, the avoidance cavity 3231 formed by the driven rod 323 can accommodate the stop portion 3210 on the active rod 321, so that the overall structure of the active rod 321 and the driven rod 323 is more compact, and the arched portion can be used as the second abutment portion 3230 to abut the locking cavity 3020 of the speaker 302, thereby enhancing the locking effect of the locking mechanism 303.

[0136] On the other hand, when the active rod 321 is in line with the connecting rod 322, if the driven rod 323 uses a straight rod structure, in order to avoid the first rotating pair 3240, the lengths of the driven rod 323 and the connecting rod 322 need to be set longer to ensure that the connecting rod 322 can be rotated to a position in line with the active rod 321. After the driven rod 323 is arched toward the side away from the active rod 321, the first rotating pair 3240 can be located in the avoidance cavity 3231, so that the driven rod 323 can avoid the first rotating pair 3240, and the lengths of the driven rod 323 and the connecting rod 322 can be set shorter, thereby reducing the occupied volume of the driven rod 323 and the connecting rod 322.

[0137] In summary, the structure of the driven rod 323 in the locking mechanism 303 provided in the present application can reduce the occupied volume of the locking mechanism 303 while ensuring the locking effect, thereby improving the compactness of the locking mechanism 303.

[0138] The specific structure of the driven rod 323 is further described below.

[0139] Continue reading Fig. 9 and Fig.12 In some embodiments of the present application, the driven rod 323 may include a first avoidance section 3232 and a second avoidance section 3233, the first avoidance section 3232 is rotatably connected to the mounting bracket 301, the second avoidance section 3233 is connected to the first avoidance section 3232, and the second avoidance section 3233 is arranged at an angle to the first avoidance section 3232 to enclose a first avoidance cavity 3231a. In this way, when the active rod 321 and the driven rod 323 are in the same line, the stopper 3210 can be received in the first avoidance cavity 3231a.

[0140] It should be noted that the angle range between the first avoidance section 3232 and the second avoidance section 3233 needs to be set according to the structural matching of the stop part 3210, so that the movement between the stop part 3210 and the driven rod 323 does not interfere with each other, and the volume of the stop part 3210 is consistent with the volume of the first avoidance cavity 3231a.

[0141] Continue reading Fig. 9 and Fig.12 In some embodiments of the present application, the driven rod 323 may further include a third avoidance section 3234, the third avoidance section 3234 is connected to the second avoidance section 3233, and the third avoidance section 3234 and the second avoidance section 3233 are arranged at an angle to enclose a second avoidance cavity 3231b. In this way, when the active rod 321 and the driven rod 323 are in the same line, the end of the active rod 321 away from the mounting bracket 301, i.e., the first rotation pair 3240, can be received in the second avoidance cavity 3231b.

[0142] It should be noted that the angle range between the second avoidance section 3233 and the third avoidance section 3234 needs to be set according to the structural matching of the active rod 321, so that the movement between the active rod 321 and the driven rod 323 neither interferes with each other nor makes the volume of the first rotating pair 3240 consistent with the volume of the second avoidance chamber 3231b.

[0143] Continue reading Fig.11 and Fig.12 In some embodiments of the present application, the locking mechanism 303 may further include a second elastic member 3235, and the second elastic member 3235 is located between the stopper 3210 and the driven rod 323. In this way, the elastic force of the second elastic member 3235 can be used to buffer the impact force between the stopper 3210 and the driven rod 323 during the locking process, reduce the wear and vibration between the components, and ensure the service life of the locking mechanism 303.

[0144] Continue reading Fig.11 and Fig.12 In some embodiments of the present application, the second elastic member 3235 may include an elastic column, which is passed through the driven rod 323 and can abut against the stopper 3210. In order to ensure the connection strength between the elastic column and the driven rod 323 and prevent the elastic column from being separated from the driven rod 323 after multiple uses, the locking mechanism 303 may also include a pressing plate 3236 clamped on the driven rod 323. The elastic column has a thicker section and a thinner section, and a step surface is formed at the connection position. The thinner section of the elastic column abuts against the stopper 3210 after passing through the through hole of the pressing plate 3236.

[0145] In this way, the pressing plate 3236 can abut against the step surface of the elastic column so as to limit the elastic column in the fixed cavity formed by the driven rod 323 and the pressing plate 3236 .

[0146] Fig.13 Another schematic diagram of the assembly structure of the sound system provided in the embodiment of the present application, in conjunction with reference to Fig.12 and Fig.13 In some embodiments of the present application, the locking mechanism 303 may further include a connecting seat 33, the connecting seat 33 is connected to the side wall of the mounting bracket 301, and the connecting seat 33 may include a rotating bracket 331, and the rotating bracket 331 is rotatably connected to the active rod 321. In this way, the rotating bracket 331 can provide a stable rotation fulcrum for the active rod 321, and the active rod 321 can be stably connected to the mounting bracket 301.

The driving assembly 31 may include a motor 311, and the motor 311 is connected to the fixed bracket 332, and the output shaft of the motor 311 is perpendicular to the active rod 321.

[0148] In this way, the motor 311 can be arranged by utilizing the space of the fixing bracket 332 in the height direction, so as to improve the structural compactness of the locking mechanism 303 .

[0149] Continue reading Fig.12 In some embodiments of the present application, the driving assembly 31 may further include a reduction gear system 312 , the input end of the reduction gear system 312 is transmission-connected to the output shaft of the motor 311 , and the output end of the reduction gear system 312 is transmission-connected to the active rod 321 .

[0150] It can be understood that the reduction gear system 312 can play a role of reducing speed and increasing torque in the locking mechanism 303 , and transmit the torque of the motor 311 to the active rod 321 smoothly and powerfully.

[0151] In addition, since the output shaft of the motor 311 and the active rod 321 are arranged vertically, in some embodiments, a worm wheel can be arranged in the reduction gear system 312 to mesh with the worm sleeved on the output shaft, thereby changing the rotation direction of the power of the motor 311.

[0152] In some other embodiments, a bevel gear may be provided in the reduction gear system 312 to mesh with another bevel gear sleeved on the output shaft, thereby changing the rotation direction of the power of the motor 311 .

[0153] Continue reading Fig.12 In some embodiments of the present application, the locking mechanism 303 may further include a limiting cover 34, the limiting cover 34 is connected to the connecting seat 33, the limiting cover 34 forms a limiting groove, and some gears in the reduction gear system 312 are arranged in the limiting groove. In this way, the limiting cover 34 can provide stable support for the rotation of the gear.

[0154] In some embodiments of the present application, the connecting seat 33 may also include a accommodating bracket 333, which is respectively connected to the rotating bracket 331 and the fixed bracket 332, and the accommodating bracket 333 is connected to the limiting cover body 34 to form a gear cavity, and another part of the gears in the reduction gear system 312 are arranged in the gear cavity.

[0155] In this way, engine oil can be injected into the gear cavity to provide lubrication and cooling for the reduction gear system 312 and ensure the stability of the power transmission process.
