[0071] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0073] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0074] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly.

[0077] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0078] Vehicles are typically equipped with an onboard actuation system, which plays music and other audio to provide a comfortable driving and riding experience for passengers.

[0079] Based on this, this application provides a vehicle, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the external structure of vehicle 1000, which includes a vehicle body 200 and an in-vehicle audio system. The in-vehicle audio system includes an in-vehicle actuation assembly 100. The in-vehicle actuation assembly 100 is connected to the vehicle body 200.

[0080] This application also provides another vehicle 1000, which includes a vehicle body 200 and an on-board actuation assembly 100.

[0081] like Figure 2 , Figure 3 As shown, Figure 2 for Figure 1 A schematic diagram showing the connection relationship between the vehicle-mounted actuation assembly 100 and the vehicle body 200. Figure 3 for Figure 2 The diagram shows the external structure of the vehicle-mounted actuation assembly 100. The vehicle-mounted audio system also includes an audio unit 20. The vehicle-mounted actuation assembly 100 includes a housing 30 and an ejection device 10.

[0082] like Figure 4 As shown, Figure 4 for Figure 3 An exploded view of the vehicle-mounted actuation assembly 100 shows that the housing 30 has a mounting cavity 301. (As shown...) Figure 5 , Figure 6 As shown, Figure 5 for Figure 3 A partial cross-sectional schematic diagram of the CRRC-mounted actuation assembly 100. Figure 6 for Figure 3 Another cross-sectional view of the vehicle-mounted actuation assembly 100 shows the speaker body 20 placed inside the mounting cavity 301. An ejection device 10 is connected to the housing 30 and is used to move the speaker body 20.

[0083] It should be noted that the speaker body 20 can be used inside the mounting cavity 301, or it can be removed from the mounting cavity 301 and moved to the outside of the vehicle 1000 for use.

[0084] Specifically, such as Figure 7 , Figure 8 As shown, Figure 7 for Figure 6 A schematic diagram of the external structure of the ejection device 10. Figure 8 for Figure 6 An exploded view of the ejection device 10, which includes a housing 1, a support 2, and a drive assembly 3.

[0085] The support member 2 is used to house the audio unit 20 of the vehicle actuation assembly 100. The support member 2 is connected to the housing 1 and is movable relative to the housing 1 to move the audio unit 20. The drive assembly 3 is connected to the support member 2 and is used to drive the support member 2 to move.

[0086] With the above settings, when it is necessary to remove the speaker body 20 from the mounting cavity 301, the drive component 3 can be activated to drive the support member 2 to move, thereby moving the speaker body 20.

[0087] In this way, the audio unit 20 can be moved to a suitable position by the drive component 3 to drive the support component 2, making it convenient for drivers and passengers to access. This makes it easier for drivers and passengers to use the audio unit 20, thereby improving their user experience of the vehicle actuation assembly 100 and ultimately enhancing their driving experience of the vehicle 1000.

[0088] In the above situation, the speaker body 20 can be driven by the push-out device 10, so that the speaker body 20 extends into or out of the mounting cavity 301 of the cabinet 30.

[0089] In this way, when the speaker unit 20 is not needed, it remains within the mounting cavity 301, and the enclosure 30 protects it. When the speaker unit 20 needs to be accessed, it can be pushed out of the mounting cavity 301 using the push-out device 10, making it easier for passengers to remove it from the cavity and improving their driving experience.

[0090] In some embodiments, the vehicle body 200 is provided with mounting holes, and the vehicle actuation assembly 100 is disposed in the mounting holes, thereby realizing the connection between the audio assembly and the vehicle body 200.

[0091] For example, the mounting hole can communicate with the passenger compartment and extend along the height direction of the vehicle 1000.

[0092] For example, the mounting hole communicates with the interior space of the trunk of vehicle 1000 and extends along the width direction of vehicle 1000.

[0093] In this way, the vehicle actuation assembly 100 can be located in the trunk of the vehicle 1000, which saves space in the passenger compartment, thereby improving the utilization rate of the interior space and further enhancing the driving experience of the passengers in the vehicle 1000.

[0094] In some embodiments, the drive component 3 can be a linear motor, which drives the support 2 to move.

[0095] In some embodiments, such as Figure 7 , Figure 8 As shown, the drive assembly 3 includes a rotating member 31, which is rotatably connected to the housing 1 around a first axis and is connected to the support member 2. The rotation of the rotating member 31 can drive the support member 2 to move along the direction of the first axis.

[0096] With the above configuration, compared to the drive assembly 3 being a linear motor, when the drive assembly 3 includes a rotating member 31, since the rotating member 31 rotates around the first axis and drives the support member 2 to move along the direction of the first axis, the space required for the rotating member 31 to rotate is smaller. This can reduce the volume of the ejection device 10, thereby improving the integration of the ejection device 10 and facilitating the spatial arrangement of the ejection device 10.

[0097] In some embodiments, the rotating member 31 includes a rotating disk with a cam surface on the side of the rotating disk facing the support member 2, and the support member 2 is moved by the cam surface.

[0098] In other embodiments, such as Figure 7 , Figure 8 As shown, the support member 2 is provided with a screw hole 21. The rotating member 31 includes a screw 311, which is threadedly connected to the screw hole 21.

[0099] With the above configuration, during the rotation of the screw 311, the screw 311 can push the support member 2 to move along the axial direction of the screw 311, thereby causing the support member 2 to move the speaker body 20. Compared with rotating parts, including rotating disks, the screw 311 requires less space, which can further reduce the volume of the ejection device 10, thereby further facilitating the spatial arrangement of the ejection device 10.

[0100] In some embodiments, such as Figure 7 , Figure 8 As shown, the drive assembly 3 also includes an electric drive component 32, which is connected to the rotating component 31 and is used to drive the rotating component 31 to rotate.

[0101] In some examples, the electric drive unit 32 includes a motor.

[0102] With the above settings, when the audio unit 20 needs to be accessed, the electric drive unit 32 can be activated, which will automatically drive the rotating part 31 to rotate, thereby realizing the automatic movement of the support 2. Compared with the driver and passengers manually driving the rotating part 31 to rotate, the operation process of the driver and passengers can be simplified, which can further facilitate the driver and passengers to access the audio unit 20 and improve the driving experience of the driver and passengers in the vehicle 1000.

[0103] In some embodiments, such as Figure 8 , Figure 9 As shown, Figure 9 for Figure 8The diagram shows the external structure of the reducer 33. The drive assembly 3 also includes the reducer 33. The output shaft of the drive assembly 3 is connected to the reducer 33, and the reducer 33 is connected to the rotating part 31.

[0104] In this way, compared to the output shaft of the drive assembly 3 being directly connected to the rotating part 31, the speed of the rotating part 31 can be reduced and the torque of the rotating part 31 can be increased by setting the reducer 33, so that the rotating part 31 can rotate more smoothly and ensure the stable operation of the ejection device 10.

[0105] In some embodiments, the reducer 33 includes a turbine and a worm, the worm being connected to the output shaft of the drive assembly 3, the worm being connected to the rotating member, and the turbine meshing with the worm.

[0106] In some embodiments, such as Figure 8 , Figure 9 As shown, the reducer 33 includes at least two meshing gears 331.

[0107] With the above configuration, compared to the reducer 33 including a worm and a gear, when the reducer 33 includes at least two meshing gears 331, the axial direction of the output shaft of the drive assembly 3 is consistent with the direction of the first axis. This can reduce the space occupied by the drive assembly 3 in the direction perpendicular to the first axis, thereby further improving the integration of the ejection device 10.

[0108] Based on this, in some embodiments, such as Figure 8 As shown, the support member 2 includes a support plate 22, and the plane on which the support plate 22 is located is perpendicular to the direction of movement of the support member 2.

[0109] With the above configuration, since the plane where the support plate 22 is located is perpendicular to the direction of movement of the support member 2, the force exerted by the support plate 22 on the speaker body 20 during the movement of the support member 2 is consistent with the direction of movement of the support member 2.

[0110] In this way, during the movement of the support member 2, the support member 2 can drive the speaker body 20 to move more stably, thereby ensuring the pushing effect of the push device 10 on the speaker body 20.

[0111] In some embodiments, such as Figure 8 As shown, the housing 1 is provided with a limiting groove 11. The support member 2 also includes a limiting member 23, which is connected to the support plate 22 and slidably connected within the limiting groove 11.

[0112] For example, the limiting component 23 can be a limiting plate, a limiting rod, etc.

[0113] With the above configuration, during the movement of the support member 2, the limiting groove 11 can limit the limiting member 23, thereby restricting the movement direction of the support plate 22, ensuring the stability of the ejection device 10 during operation, and further ensuring the pushing effect of the ejection device 10 on the speaker body 20.

[0114] In some embodiments, such as Figure 8 As shown, the support member 2 is provided with a guide hole 24 extending along the direction of the first axis.

[0115] The ejection device 10 also includes a guide 4, which is connected to the housing 1 and passes through the guide hole 24.

[0116] For example, guide member 4 can be a guide rod, guide plate, etc.

[0117] With the above configuration, since the guide rod passes through the guide hole 24, the guide rod is connected to the housing 1, and the axial direction of the guide rod is consistent with the direction of the first axis, the guide rod can restrict the support member 2 from moving in a direction perpendicular to the first axis.

[0118] In this way, during the rotation of the rotating part 31, the guide rod can guide the support part 2, so that the support part 2 moves along the direction of the first axis, thereby realizing the pushing function of the ejection device 10 on the speaker body 20.

[0119] In some examples, such as Figure 8 As shown, the support member 2 also includes a connecting plate 25, the plane of which is perpendicular to the moving direction of the support member 2. The connecting plate 25 is connected to the side of the support plate 22 facing away from the speaker body 20, and the guide hole 24 and the screw hole 21 are both provided on the connecting plate 25.

[0120] In some embodiments, such as Figure 7 , Figure 8 As shown, the housing 1 has a receiving space 12, and the drive assembly 3 is located within the receiving space 12. Part of the support member 2 is located within the receiving space 12, and the other part of the support member 2 is located outside the housing 1, for placing the audio body 20 of the vehicle actuation assembly 100.

[0121] With the above configuration, the housing 1 can partially shield the drive assembly 3 and the support member 2, thereby protecting the drive assembly 3 and the support member 2. Since the other part of the support member 2 is located outside the housing 1, the audio body 20 will not be blocked by the housing 1 during the movement of the audio body 20 driven by the support member 2, so as to ensure the function of the ejection device 10 in ejecting the audio body 20.

[0122] Based on this, in some embodiments, such as Figure 8As shown, the housing 1 includes a first part 13 and a second part 14. The first part 13 is provided with a first receiving cavity 15. The second part 14 and the first part 13 define a second receiving cavity 16. The first receiving cavity 15 and the second receiving cavity 16 form a receiving space 12. A portion of the driving component 3 is disposed in the first receiving cavity 15, and another portion of the driving component 3 is disposed in the second receiving cavity 16.

[0123] With the above configuration, compared to the shell 1 being a one-piece molded structure, when the shell 1 includes a first part 13 and a second part 14, the first part 13 and the second part 14 can be processed separately, and then the first part 13 and the second part 14 can be connected together. This simplifies the processing of the shell 1 and makes it easier to process the shell 1.

[0124] Meanwhile, by setting up the first receiving cavity 15 and the second receiving cavity 16, the drive assembly 3 can be installed in both the first receiving cavity 15 and the second receiving cavity 16 at the same time. This facilitates the spatial arrangement of the drive assembly 3 and allows for the separate installation of one part and another part of the drive assembly 3, thus facilitating the installation of the drive assembly 3.

[0125] In some embodiments, such as Figure 8 As shown, the rotating component 31 and the electric drive component 32 are disposed in the first receiving cavity 15, and the reducer 33 is disposed in the second receiving cavity 16.

[0126] With the above settings, during the installation of the drive assembly 3, the reducer 33 can be installed into the second receiving cavity 16 first, and then the electric drive component 32 and the rotating component 31 can be connected to the reducer 33 respectively. This simplifies the installation process of the drive assembly 3 and makes the installation of the drive assembly 3 more convenient.

[0127] In some embodiments, such as Figure 8 As shown, the first part 13 is provided with a first limiting groove 131, and the second part 14 is provided with a second limiting groove 141. The first limiting groove 131 and the second limiting groove 141 are connected to form a limiting groove 11.

[0128] With the above configuration, the limiting member 23 can slide within the second limiting groove 141 and the first limiting groove 131, so that the limiting member 23 will not be blocked by the first part 13 or the second part 14, thus having a larger movement distance. In this way, the support member 2 can also have a larger movement distance, thereby increasing the distance that the support member 2 can drive the speaker body 20 to move, thereby improving the pushing effect of the pushing device 10 on the speaker body 20.

[0129] Based on this, in some embodiments, such as Figure 8As shown, the inner wall surface of the limiting groove 11 in the first direction is the first inner wall surface, and the first direction is perpendicular to the sliding direction of the limiting member 23. The second limiting groove 141 is provided with a first protrusion 1311, which is located between the first inner wall surface and the limiting member 23.

[0130] For example, the number of first protrusions 1311 can be one or more.

[0131] With the above configuration, since the first protrusion 1311 is located between the first inner wall surface and the limiting member 23, the first protrusion 1311 can restrict the limiting member 23 from moving towards the first inner wall surface. In this way, during the movement of the limiting member 23, the limiting member 23 will not contact the first inner wall surface, thus preventing abnormal noises caused by collisions between the limiting member 23 and the first inner wall surface, and improving the comfort of the driver and passengers when driving the vehicle 1000.

[0132] In some examples, the inner wall surface of the limiting groove 11 on the other side in the first direction is the second inner wall surface, and the second limiting groove 141 is provided with a second protrusion, which is located between the first inner wall surface and the limiting member 23.

[0133] In some embodiments, such as Figure 8 As shown, the first part 13 includes a housing 132 and a first baffle 133.

[0134] The outer casing 132 has a first receiving cavity 15 and a first opening communicating with the first receiving cavity 16. The first opening is located on the side of the first receiving cavity 15 opposite to the second part 14. A first baffle 133 covers the first opening and is detachably connected to the outer casing 132.

[0135] With the above settings, during the installation of the drive assembly 3 and the rotating component 31, the first baffle 133 can be separated from the outer shell 132 to open the first opening, thereby facilitating the installation of the drive assembly 3 and the rotating component 31 into the first receiving cavity 15. After the drive assembly 3 and the rotating component 31 are installed into the first receiving cavity 15, the first baffle 133 is then covered to cover the first opening, thereby completing the installation of the drive assembly 3 and the rotating component 31.

[0136] In addition, when the drive assembly 3 or the rotating part 31 needs maintenance or replacement, the first baffle 133 can be removed from the housing 132 to facilitate the removal of the drive assembly 3 or the rotating part 31 from the first receiving cavity 15, thereby facilitating the maintenance or replacement of the drive assembly 3 or the rotating part 31.

[0137] In some examples, such as Figure 8 As shown, the second part 14 includes a cover plate 142 and a second baffle 143. The cover plate 142 is connected to the first part 13 and defines a second receiving cavity 16 with the first part 13.

[0138] The second baffle 143 is connected to the side of the cover plate 142 facing away from the first part 13. The second limiting groove 141 is recessed from one side surface of the second part 14 in the first direction to the other side surface, and the second limiting groove 141 extends from the side surface of the cover plate 142 facing the first part 13 to the second baffle 143.

[0139] For example, the cover plate 142 and the second baffle 143 can be separate structures or integrally formed structures.

[0140] With the above configuration, since the second limiting groove 141 extends from the side surface of the cover plate 142 towards the first part 13 to the second baffle 143, the first limiting groove 131 can communicate with the second limiting groove 141, thereby forming a limiting groove 11. Furthermore, compared to the second part 14 being a mounting block, the use of the cover plate 142 and the second baffle 143 reduces the material required for processing the second part 14 and saves the space occupied by the second part 14, thus reducing the processing cost of the second part 14 and facilitating its spatial arrangement.

[0141] In some examples, housing 132 includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall. The second sidewall is disposed opposite to the first sidewall. The third sidewall connects between the first and second sidewalls and defines a second receiving cavity 16 with cover plate 142.

[0142] The fourth sidewall is located on one side of the third sidewall in the first direction and is connected between the first and second sidewalls. The first baffle 133 is connected between the first and second sidewalls and is located on the side of the third sidewall opposite to the cover plate 142.

[0143] The first sidewall, the second sidewall, the third sidewall, the fourth sidewall, and the first baffle 133 form a first receiving cavity 15 and a first limiting groove 131, with the first limiting groove 131 located on the other side of the third sidewall in the first direction.

[0144] It is understandable that, under the above circumstances, the first limiting groove 131 is connected to the first receiving cavity 15.

[0145] Based on this, in some embodiments, such as Figure 7 , Figure 8 As shown, the ejection device 10 also includes a control circuit board 5, which is connected to the housing 1 and is used to control the drive assembly 3 to drive the support member 2 to move.

[0146] The support member 2 is movable between a first position and a second position. In the first position, the ejection device 10 is in the retracted state. In the second position, the ejection device 10 is in the ejected state.

[0147] With the above settings, the support member 2 can be moved between the first position and the second position by the control circuit board 5, thereby driving the speaker body 20 to move.

[0148] In some embodiments, the control circuit board 5 is configured as follows:

[0149] After receiving the start-up information of the control drive component 3, the position information of the support component 2 is obtained, and it is determined whether the support component 2 is in the first position.

[0150] If the support member 2 is in the first position, the control drive assembly 3 drives the support member 2 to move from the first position to the second position.

[0151] With the above settings, when the control circuit board 5 receives the information to start the control drive component 3, if the support member 2 is in the first position, it means that the ejection device 10 is in the retracted state and can be ejected normally. The control circuit board 5 will then control the drive component 3 to start, so that the support member 2 moves from the first position to the second position, thereby changing the ejection device 10 from the retracted state to the ejection state, and realizing the ejection of the speaker body 20.

[0152] In some embodiments, the control circuit board 5 is further configured to:

[0153] If the support member 2 is in the second position, the control drive assembly 3 drives the support member 2 to move from the second position to the first position.

[0154] With the above settings, after the control circuit board 5 controls the drive assembly 3 to drive the support member 2 to move from the first position to the second position, the control circuit board 5 will control the drive assembly 3 to drive the support member 2 to move from the second position to the first position, thereby realizing the automatic retraction of the push-out device 10, which facilitates the use of the audio body 20 by the driver and passengers.

[0155] Meanwhile, compared to the support member 2 being fixed after moving to the second position, when the support member 2 automatically retracts, it can prevent the driver and passengers from placing the audio body 20 on the support member 2 and pushing the second support member 2 when the support member 2 is in the second position, which would cause damage to the drive component 3, thereby protecting the drive component 3.

[0156] In some embodiments, such as Figure 2 , Figure 3 As shown, the ejection device 10 also includes a button 6, which is electrically connected to the control circuit board 5 and is used to send start / stop information of the drive component 3 to the control circuit board 5.

[0157] In this way, when the driver or passenger needs to access the audio unit 20, the driver or passenger can press the button 6 to send start / stop information of the drive component 3 to the control circuit board 5, thereby controlling the drive component 3 to start, so that the drive component 3 drives the support member 2 to move from the first position to the second position.

[0158] In some embodiments, the control circuit board 5 is further configured to:

[0159] Get the duration of button 6 being pressed, and determine whether the duration of button 6 being pressed is greater than or equal to the preset duration;

[0160] If the pressing duration of button 6 is greater than or equal to the preset duration, the control drive component 3 will be activated.

[0161] For example, the preset duration can be 1s, 2s, 3s, etc.

[0162] With the above settings, when the pressing time of button 6 is greater than or equal to the preset time, the control circuit board 5 can normally control the drive component 3 to start. When the pressing time of button 6 is less than the preset time, the control circuit board 5 will not control the drive component 3 to start, thus preventing the driver and passengers from accidentally touching button 6, thereby ensuring the normal use of the ejection device 10.

[0163] In some embodiments, the ejection device 10 further includes an indicator light, which is electrically connected to the control circuit board 5 and is used to indicate the position of the support member 2.

[0164] With the above settings, the position of the support member 2 can be indicated by changing the state of the indicator light (e.g., color, duration of illumination, etc.), thereby making it convenient for drivers and passengers to use the push-out device 10.

[0165] In some embodiments, the control circuit board 5 is further configured to:

[0166] When the information for starting the control drive component 3 is received, it is determined whether the support component 2 is in the first position.

[0167] If the support member 2 is in the first position, the control indicator light will display the first color.

[0168] If support 2 is not in the first position, the control indicator light will display the second color.

[0169] With the above settings, when the drive component 3 needs to be started, the driver and passengers can judge whether the drive component 3 can be started normally by observing the color of the indicator light. If the indicator light shows the first color (such as green, blue, etc.), it means that the support 2 is in the first position and the drive component 3 can be started normally.

[0170] If the indicator light displays a second color (e.g., red, yellow, etc.), it means that the support member 2 is not in the first position and the drive component 3 cannot start normally. This allows the driver and passengers to understand the position information of the support member 2, thereby connecting the working status of the push-out device 10 and facilitating the use of the push-out device 10 by the driver and passengers.

[0171] In some embodiments, the control circuit board 5 is further configured to:

[0172] After the drive component 3 is started, it is determined whether the support component 2 is in the second position.

[0173] If support 2 is not in the second position, the control indicator light will flash.

[0174] If the support member 2 is in the second position, the control drive assembly 3 drives the support member 2 to move from the second position to the first position and controls the indicator light to stay on.

[0175] With the above settings, after the drive component 3 is started, the driver and passengers can determine the position of the support member 2 by observing the duration of the indicator light. If the indicator light flashes, it means that the support member 2 is between the first position and the second position.

[0176] If the indicator light stays on, it means that the support 2 is in the second position. At this time, the push-out device 10 is in the push-out state, and the driver and passengers can take out the audio unit 20. This also makes it convenient for the driver and passengers to use the push-out device 10.

[0177] In some embodiments, the ejection device 10 further includes a locking structure electrically connected to the control circuit board 5 for locking the speaker body 20 when the support plate 22 is in a first position.

[0178] With the above settings, the locking mechanism can lock the speaker body 20 when the support member 2 is in the first position, thereby restricting the movement of the speaker body 20 relative to the support member 2. This ensures the stability of the speaker body 20 placed on the support member 2 and prevents the speaker body 20 from being bumped or knocked after it moves, thus protecting the speaker body 20.

[0179] In some examples, the locking structure includes a locking protrusion and a locking groove on the outer surface of the speaker body 20. When the support 2 is in the first position, the locking protrusion can extend into the locking groove to lock the speaker body 20.

[0180] In some embodiments, the control circuit board 5 is further configured to:

[0181] After the support member 2 moves from the second position to the first position, if a locking instruction is received, the locking structure is controlled to lock the speaker body 20.

[0182] With the above settings, when the support member 2 moves to the first position, it indicates that the ejection device 10 is in the retracted state. If the control circuit board 5 receives the locking instruction information at this time, it means that the speaker body 20 has been placed on the support member 2. The control circuit board 5 will then control the locking structure to lock the speaker body 20, thereby fixing the speaker body 20.

[0183] In some embodiments, such as Figure 7 , Figure 8 As shown, the ejection device 10 also includes a touch control 7, which is connected to the housing 1, such as... Figure 10 , Figure 11 As shown, Figure 10 for Figure 3 Another partial cross-sectional schematic diagram of the CRRC-mounted actuation assembly 100. Figure 11 for Figure 10 The enlarged view at point A shows that the touch control 7 is used to send a lock indication message to the control circuit board 5 when touched by the speaker body 20.

[0184] With the above settings, when the speaker body 20 touches the touch control 7, the touch control 7 will send a locking instruction to the control circuit board 5, so that the control circuit board 5 controls the locking structure to lock the speaker body 20.

[0185] Compared to using position sensors (such as infrared sensors), sending locking indication information via touch control 7 simplifies the structure of the ejection device 10 and reduces its size. This facilitates the spatial arrangement of the ejection device 10.

[0186] For example, the touch control 7 is a button 6 switch.

[0187] For example, the touch control 7 is a micro switch.

[0188] With the above settings, compared to the button 6 switch, when the touch control 7 is a micro switch, the space required for the touch control 7 is smaller, which can further reduce the volume of the ejection device 10 and facilitate the space setting of the ejection device 10.

[0189] In some embodiments, such as Figure 3 , Figure 4 As shown, the housing 30 is provided with an installation port 302, which communicates with the installation cavity 301. The ejection device 10 is connected to the outside of the housing 30 and covers the installation port 302.

[0190] In some embodiments, a portion of the support member 2 can extend into the mounting cavity 301 through the mounting port 302, and the speaker body 20 is placed in the portion of the support member 2 that extends into the mounting cavity 301.

[0191] With the above configuration, part of the support member 2 can extend into the mounting cavity 301 through the mounting port 302, thereby driving the speaker body 20 inside the mounting cavity 301 to move. Compared to the ejection device 10 being located inside the mounting cavity 301, when the ejection device 10 is located outside the housing 30, there is a larger installation space outside the housing 30, which facilitates the spatial arrangement of the vehicle actuation assembly 100.

[0192] In some examples, the second baffle 143 is connected to the housing 30, and the housing 30 covers the second limiting groove 141. In this way, the limiting plate can be limited by the cooperation of the housing 30 and the second baffle 143.

[0193] In some embodiments, such as Figure 8 As shown, the housing 1 is provided with a second opening 17, which is connected to the mounting port 302.

[0194] In this way, another part of the support member 2 can be located inside the housing 1, and part of the support member 2 extends into the mounting cavity 301 through the second opening 17. Thus, the housing 1 can shield the support member 2, thereby protecting the support member 2 and preventing it from being damaged.

[0195] In some examples, such as Figure 12 , Figure 13 As shown, Figure 12 for Figure 6 A schematic diagram of the external structure of the ejection device 10. Figure 13 for Figure 12 A cross-sectional schematic diagram of the ejection device 10 shows that the second opening 17 forms the first limiting groove 131. When the support member 2 is in the second position, part of the limiting member 23 is located in the first limiting groove 131, and the other part is located in the second limiting groove 141.

[0196] With the above settings, when the support member 2 is in the first position, the limiting member 23 can block the second opening 17 to prevent debris from entering the first receiving cavity 15.

[0197] In some embodiments, the speaker body 20 can extend into or out of the mounting cavity 301 in a second direction.

[0198] like Figure 4 As shown, along a direction perpendicular to the second direction, at least one first connecting part 201 is provided on the outer wall surface of the speaker body 20, and at least one second connecting part 303 is provided on the inner wall surface of the mounting cavity 301, and the second connecting part 303 is engaged with the first connecting part 201.

[0199] With the above configuration, after the speaker body 20 is placed in the mounting cavity 301, the second connecting part 303 can engage with the first connecting part 201, thereby fixing the speaker body 20 in the mounting cavity 301. This can further improve the stability of the speaker body 20 placed in the mounting cavity 301 and prevent the speaker body 20 from being damaged after being bumped.

[0200] In some examples, the first connecting portion 201 includes a snap-fit ​​groove, and the second connecting portion 303 includes a snap-fit ​​protrusion that extends into the snap-fit ​​groove to achieve snap-fit ​​between the first connecting portion 201 and the second connecting portion 303.

[0201] In some embodiments, such as Figure 10 As shown, a handle 202 is provided on the outer wall surface of the speaker body 20 along a direction perpendicular to the second direction.

[0202] In this way, when the driver or passenger takes out the audio unit 20, they can take it out by grabbing the handle 202, which makes it convenient for the driver or passenger to take out the audio unit 20.

[0203] In some examples, the shape of the mounting cavity 301 is the same as the shape of the speaker body 20, such as... Figure 10 As shown, a receiving groove 203 is provided on the outer surface of the speaker body 20, and the handle 202 is located in the receiving groove 203.

[0204] With the above configuration, since the handle 202 is located in the receiving groove 203, the handle 202 will not affect the insertion of the audio body 20 into the mounting cavity 301. After the audio body 20 is inserted into the mounting cavity 301, the housing 30 can cover the handle 202, thereby hiding the handle 202. This can improve the appearance of the vehicle 1000 when the audio body 20 is inserted into the mounting cavity 301.

[0205] In some embodiments, such as Figure 6 As shown, the enclosure 30 is equipped with a connector 304. The connector 304 is connected to the power supply of the vehicle 1000. The audio unit 20 is equipped with a connection port. When the audio unit 20 is placed inside the enclosure 30, the connector 304 is connected to the connection port.

[0206] In this way, when the audio unit 20 is placed in the mounting cavity 301, the audio unit 20 can be charged through the power supply of the vehicle 1000 to ensure that the audio unit 20 has sufficient power when the driver and passengers take it out, thus improving the user experience of the vehicle actuation assembly 100.

[0207] In some examples, lubricating material is provided on the inner wall of the mounting cavity 301 and the outer surface of the speaker body 20.

[0208] By using lubricating materials, the friction between the inner wall of the mounting cavity 301 and the outer surface of the speaker body 20 can be reduced, making it easier for drivers and passengers to put the speaker body 20 into the mounting cavity 301 or take the speaker body 20 out of the mounting cavity 301.

[0209] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
