DETAILED DESCRIPTION

[0071] 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.

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

[0078] Vehicles are usually equipped with an on-board actuation assembly, which plays music, etc., to provide a comfortable driving experience for the driver and passengers.

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

[0080] The present application also provides another vehicle 1000 , which includes a vehicle body 200 and a vehicle-mounted actuation assembly 100 .

[0081] like Figure 2 , Figure 3 As shown, Figure 2 for Figure 1 The schematic diagram of the connection relationship between the vehicle-mounted actuation assembly 100 and the vehicle body 200 is shown in FIG. Figure 3 for Figure 2 Schematic diagram of the external structure of the vehicle-mounted actuating assembly 100 , the vehicle-mounted audio system further includes an audio body 20 , and the vehicle-mounted actuating assembly 100 includes a box body 30 and a pushing device 10 .

[0082] like Figure 4 As shown, Figure 4 for Figure 3 In the exploded structural diagram of the vehicle-mounted actuating assembly 100, the box body 30 is formed with a mounting cavity 301. Figure 5 , Figure 6 As shown, Figure 5 for Figure 3 A partial cross-sectional schematic diagram of the vehicle-mounted actuation assembly 100, Figure 6 for Figure 3 Another partial cross-sectional schematic diagram of the vehicle-mounted actuating assembly 100 is shown in FIG. 1 , in which the sound body 20 is placed in the installation cavity 301 . The ejection device 10 is connected to the box 30 to drive the sound body 20 to move.

[0083] It should be noted that the audio body 20 can be placed in the installation cavity 301 for use, or can be taken out of the installation cavity 301 and moved to the outside of the vehicle 1000 for use.

[0084] Specifically, Figure 7 , Figure 8 As shown, Figure 7 for Figure 6 A schematic diagram of an external structure of the ejection device 10, Figure 8 for Figure 6 The schematic diagram of the exploded structure of the ejection device 10 is shown in FIG. 1 , wherein the ejection device 10 includes a housing 1 , a support member 2 and a drive assembly 3 .

[0085] The support member 2 is used to place the sound body 20 of the vehicle-mounted actuation assembly 100. The support member 2 is connected to the housing 1 and can move relative to the housing 1 to drive the sound body 20 to move. The driving component 3 is connected to the support member 2 and is used to drive the support member 2 to move.

[0086] Through the above arrangement, when the speaker body 20 needs to be taken out from the installation cavity 301 , the driving assembly 3 can be started to drive the support member 2 to move, thereby driving the speaker body 20 to move.

[0087] In this way, the driving component 3 can drive the support member 2 to move the audio body 20 to a suitable position, so as to facilitate the driver and passengers to use it. This can make it convenient for the driver and passengers to use the audio body 20, thereby improving the driver and passengers' experience of using the vehicle-mounted actuation assembly 100, and further improving the driver and passengers' driving experience of the vehicle 1000.

[0088] In the above case, the speaker body 20 can be driven by the pushing device 10 , so that the speaker body 20 extends into or out of the installation cavity 301 of the box body 30 .

[0089] In this way, when the sound body 20 is not needed, the sound body 20 is located in the installation cavity 301, and the box body 30 can protect the sound body 20. When the sound body 20 needs to be taken out, the sound body 20 can be pushed out of the installation cavity 301 by the pushing device 10, so that it is convenient for the driver and passengers to take out the sound body 20 from the installation cavity 301, thereby improving the driving experience of the driver and passengers on the vehicle 1000.

[0090] In some embodiments, the vehicle body 200 is provided with a mounting hole, and the vehicle-mounted actuating assembly 100 is disposed in the mounting hole, thereby achieving connection between the audio assembly and the vehicle body 200 .

[0091] Exemplarily, the mounting hole may be in communication with the cabin and extend in a height direction of the vehicle 1000 .

[0092] Illustratively, the mounting hole communicates with the inner space of the trunk of the vehicle 1000 and extends in the width direction of the vehicle 1000 .

[0093] In this way, the vehicle-mounted actuating assembly 100 can be arranged in the trunk of the vehicle 1000 , which can save space in the cabin, thereby improving the utilization rate of the space in the vehicle and further improving the driving experience of the driver and passengers on the vehicle 1000 .

[0094] In some embodiments, the driving assembly 3 may be a linear motor, which drives the support member 2 to move.

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

[0096] Through the above arrangement, compared with the case where the driving component 3 is a linear motor and the driving component 3 includes a rotating member 31, since the rotating member 31 rotates around the first axis and drives the supporting member 2 to move along the direction of the first axis, the space required for the rotating member 31 to rotate is smaller, which 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, and a cam surface is provided on a side of the rotating disk facing the supporting member 2, and the supporting member 2 is pushed to move by the cam surface.

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

[0099] Through the above arrangement, during the rotation of the screw rod 311, the screw rod 311 can push the support member 2 to move along the axial direction of the screw rod 311, so that the support member 2 drives the sound body 20 to move. Compared with the rotating member including the rotating disk, the screw rod 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, Figure 7 , Figure 8 As shown, the driving assembly 3 further includes an electric driving member 32 , which is connected to the rotating member 31 and is used to drive the rotating member 31 to rotate.

[0101] In some examples, electric drive 32 includes an electric motor.

[0102] Through the above-mentioned arrangement, when the audio body 20 needs to be accessed, the electric drive component 32 can be started, and the electric drive component 32 automatically drives the rotating component 31 to rotate, thereby realizing the automatic movement of the support component 2. Compared with the driver and passenger manually driving the rotating component 31 to rotate, the operation process of the driver and passenger can be simplified, so as to further facilitate the driver and passenger to access the audio body 20 and improve the driver and passenger's driving experience of the vehicle 1000.

[0103] In some embodiments, Figure 8 , Fig. 9 As shown, Fig. 9 for Figure 8Schematic diagram of the external structure of the reducer 33, the driving component 3 also includes a reducer 33, the output shaft of the driving component 3 is connected to the reducer 33, and the reducer 33 is connected to the rotating member 31.

[0104] In this way, compared with the output shaft of the driving component 3 being directly connected to the rotating member 31, the setting of the reducer 33 can reduce the rotation speed of the rotating member 31 and increase the torque of the rotating member 31, so that the rotating member 31 can rotate more smoothly to ensure the stable operation of the ejection device 10.

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

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

[0107] Through the above configuration, compared with the reducer 33 including a turbine and a worm, when the reducer 33 includes at least two meshing gears 331, the axial direction of the output shaft of the drive component 3 is consistent with the direction of the first axis, thereby reducing the space occupied by the drive component 3 in the direction perpendicular to the first axis, so as to further improve the integration of the ejection device 10.

[0108] On this basis, in some embodiments, such as Figure 8 As shown, the support member 2 includes a support plate 22 , and the plane where the support plate 22 is located is perpendicular to the moving direction of the support member 2 .

[0109] Through the above arrangement, since the plane where the support plate 22 is located is perpendicular to the moving direction of the support member 2 , during the movement of the support member 2 , the force applied by the support plate 22 to the audio body 20 is consistent with the moving direction of the support member 2 .

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

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

[0112] Exemplarily, the limiting member 23 may be a limiting plate, a limiting rod, or the like.

[0113] Through the above arrangement, during the movement of the support member 2, the limiting groove 11 can limit the limiting member 23, thereby limiting the moving direction of the support plate 22, so as to ensure the stability of the ejection device 10 during operation, and further ensure the pushing effect of the ejection device 10 on the speaker body 20.

[0114] In some embodiments, 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 further includes a guide member 4 , which is connected to the housing 1 and passes through the guide hole 24 .

[0116] Exemplarily, the guide member 4 may be a guide rod, a guide plate, or the like.

[0117] Through the above arrangement, since the guide rod is inserted into the guide hole 24, 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 limit the movement of the support member 2 in a direction perpendicular to the first axis.

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

[0119] In some examples, such as Figure 8 As shown, the support member 2 further 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 sound body 20, and the guide hole 24 and the screw hole 21 are both provided on the connecting plate 25.

[0120] In some embodiments, Figure 7 , Figure 8 As shown, the housing 1 is provided with a receiving space 12, and the driving assembly 3 is disposed in the receiving space 12. Part of the support member 2 is disposed in the receiving space 12, and another part of the support member 2 is disposed outside the housing 1 for placing the sound body 20 of the vehicle-mounted actuating assembly 100.

[0121] Through the above-mentioned arrangement, the shell 1 can cover part of the driving component 3 and the support member 2, thereby protecting the driving component 3 and the support member 2, and because the other part of the support member 2 is arranged outside the shell 1, the audio body 20 will not be blocked by the shell 1 during the process of the support member 2 driving the audio body 20 to move, so as to ensure the ejection function of the audio body 20 by the ejection device 10.

[0122] On this basis, in some embodiments, such as Figure 8As shown, the shell 1 includes a first part 13 and a second part 14, the first part 13 is provided with a first accommodating cavity, the second part 14 and the first part 13 define a second accommodating cavity, the first accommodating cavity and the second accommodating cavity form an accommodating space 12, part of the driving component 3 is arranged in the first accommodating cavity, and the other part of the driving component 3 is arranged in the second accommodating cavity.

[0123] Through the above arrangement, compared with the case where the shell 1 is an integrally formed structure, when the shell 1 includes the first part 13 and the 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, which can simplify the processing of the shell 1 and facilitate the processing of the shell 1.

[0124] At the same time, through the setting of the first installation cavity 15 and the second installation cavity 16, the drive component 3 can be installed in the first installation cavity 15 and the second installation cavity 16 at the same time, which can facilitate the spatial setting of the drive component 3, and can install part and another part of the drive component 3 separately, so as to facilitate the installation of the drive component 3.

[0125] In some embodiments, Figure 8 As shown, the rotating member 31 and the electric driving member 32 are arranged in the first accommodating chamber, and the reducer 33 is arranged in the second accommodating chamber.

[0126] Through the above-mentioned arrangement, during the installation of the drive component 3, the reducer 33 can be first installed in the second installation cavity 16, and then the electric drive component 32 and the rotating component 31 can be respectively connected to the reducer 33, which can simplify the installation process of the drive component 3 and facilitate the installation of the drive component 3.

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

[0128] Through the above arrangement, the limiting member 23 can be moved from 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, thereby having a larger moving distance. In this way, the support member 2 can also have a larger moving distance, thereby increasing the distance that the support member 2 drives the speaker body 20 to move, thereby improving the effect of the push-out device 10 on the speaker body 20.

[0129] On this basis, 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. A first protrusion 1311 is provided in the second limiting groove 141, and the first protrusion 1311 is provided between the first inner wall surface and the limiting member 23.

[0130] Illustratively, the number of the first protrusion 1311 may be one or more.

[0131] Through the above arrangement, since the first protrusion 1311 is disposed between the first inner wall surface and the stopper 23, the first protrusion 1311 can limit the movement of the stopper 23 in the direction close to the first inner wall surface. In this way, during the movement of the stopper 23, the stopper 23 will not contact the first inner wall surface, thus avoiding the stopper 23 and the first inner wall surface from colliding and generating abnormal noise, thereby improving the comfort of the driver and passengers when driving the vehicle 1000.

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

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

[0134] The housing 132 is provided with a first accommodating cavity and a first opening communicating with the first accommodating cavity, and the first opening is located at a side of the first accommodating cavity facing away from the second portion 14. The first baffle 133 covers the first opening and is detachably connected to the housing 132.

[0135] Through the above-mentioned arrangement, during the process of installing the driving component 3 and the rotating member 31, the first baffle 133 can be separated from the outer shell 132 to open the first opening, thereby facilitating the installation of the driving component 3 and the rotating member 31 into the first accommodating cavity. After the driving component 3 and the rotating member 31 are installed into the first accommodating cavity, the first baffle 133 covers the first opening to complete the installation of the driving component 3 and the rotating member 31.

[0136] In addition, when the driving component 3 or the rotating part 31 needs maintenance or replacement, the first baffle 133 can be removed from the outer shell 132 to facilitate the removal of the driving component 3 or the rotating part 31 from the first accommodating cavity, thereby facilitating the maintenance or replacement of the driving component 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 plate 143. The cover plate 142 is connected to the first part 13, and defines a second accommodating cavity 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, and 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 toward the first part 13 to the second baffle 143.

[0139] Exemplarily, the cover plate 142 and the second baffle plate 143 may be separate structures or may be an integrally formed structure.

[0140] Through the above arrangement, since the second limiting groove 141 extends from the cover plate 142 toward the side surface of the first part 13 to the second baffle plate 143, the first limiting groove 131 can be connected with the second limiting groove 141, thereby forming the limiting groove 11. Compared with the second part 14 being a mounting block, the arrangement of the cover plate 142 and the second baffle plate 143 can reduce the material required for processing the second part 14 and save the space required for the second part 14, thereby reducing the processing cost of the second part 14 and facilitating the space arrangement of the second part 14.

[0141] In some examples, the housing 132 includes a first side wall, a second side wall, a third side wall, and a fourth side wall. The second side wall is disposed opposite to the first side wall. The third side wall is connected between the first side wall and the second side wall, and defines a second accommodation cavity with the cover plate 142.

[0142] The fourth side wall is located at one side of the third side wall in the first direction and connected between the first side wall and the second side wall. The first baffle 133 is connected between the first side wall and the second side wall and is located at a side of the third side wall facing away from the cover plate 142 .

[0143] The first side wall, the second side wall, the third side wall, the fourth side wall and the first baffle 133 form a first accommodating cavity and a first limiting groove 131 . The first limiting groove 131 is located on the other side of the third side wall in the first direction.

[0144] It can be understood that, in the above case, the first limiting groove 131 is communicated with the first installation cavity 15 .

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

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

[0147] Through the above arrangement, the support member 2 can be controlled to move between the first position and the second position by controlling the circuit board 5, thereby driving the speaker body 20 to move.

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

[0149] After receiving the information for starting the control driving assembly 3, the position information of the support member 2 is obtained, and it is determined whether the support member 2 is located at the first position.

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

[0151] Through the above arrangement, when the control circuit board 5 receives the information to control the start-up of the driving component 3, if the support member 2 is in the first position at this time, it means that the ejection device 10 is in a retracted state and can be ejected normally. The control circuit board 5 will control the drive component 3 to start, so that the support member 2 moves from the first position to the second position, that is, the ejection device 10 is converted from the retracted state to the ejection state, thereby realizing the ejection of the audio body 20.

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

[0153] If the support member 2 is located at the second position, the driving assembly 3 is controlled to drive the support member 2 to move from the second position to the first position.

[0154] Through the above-mentioned arrangement, after the control circuit board 5 controls the driving component 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 driving component 3 to drive the support member 2 to move from the second position to the first position, thereby realizing the automatic retraction of the ejection device 10 and facilitating the use of the audio body 20 by the driver and passengers.

[0155] At the same time, compared with the support member 2 being moved to the second position and then fixed, when the support member 2 is automatically retracted, it can prevent the driver and passengers from placing the audio body 20 on the support member 2 when the support member 2 is in the second position and pushing the second support member 2, causing damage to the drive assembly 3, thereby protecting the drive assembly 3.

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

[0157] In this way, when the driver and passenger need to use the audio body 20, the driver and passenger can transmit the start and stop information of the drive component 3 to the control circuit board 5 by pressing the button 6, thereby controlling the start of the drive component 3, 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 as:

[0159] Obtain the pressing time of button 6, and determine whether the pressing time of button 6 is greater than or equal to the preset time;

[0160] If the pressing time of the button 6 is greater than or equal to the preset time, the driving component 3 is controlled to start.

[0161] Exemplarily, the preset duration may be 1s, 2s, 3s, etc.

[0162] Through the above configuration, when the pressing time of the button 6 is greater than or equal to the preset time, the control circuit board 5 can normally control the start of the driving component 3. When the pressing time of the button 6 is less than the preset time, the control circuit board 5 will not control the start of the driving component 3, so as to prevent the driver and passenger from accidentally touching the 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] Through the above arrangement, the position of the support member 2 can be indicated by changing the state of the indicator light (such as color, lighting duration, etc.), thereby making it convenient for the driver and passengers to use the ejection device 10.

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

[0166] When the information for controlling the driving assembly 3 to start is received, it is determined whether the supporting member 2 is located at the first position.

[0167] If the support member 2 is located at the first position, the indicator light is controlled to display a first color.

[0168] If the support member 2 is not located at the first position, the indicator light is controlled to display a second color.

[0169] Through the above settings, when the drive component 3 needs to be started, the driver and passenger 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 (for example, green, blue, etc.), it means that the support member 2 is in the first position at this time and the drive component 3 can be started normally.

[0170] If the indicator light displays a second color (for example, red, yellow, etc.), it means that the support member 2 is not in the first position at this time and the drive assembly 3 cannot be started normally. This can facilitate the driver and passengers to understand the position information of the support member 2, thereby connecting the working status of the ejection device 10 and facilitating the driver and passengers to use the ejection device 10.

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

[0172] After the driving assembly 3 is started, it is determined whether the supporting member 2 is in the second position.

[0173] If the support member 2 is not located at the second position, the control indicator light flashes.

[0174] If the support member 2 is located at the second position, the driving assembly 3 is controlled to drive the support member 2 to move from the second position to the first position, and the indicator light is controlled to be always on.

[0175] Through the above arrangement, after the driving assembly 3 is started, the driver and passengers can judge the position of the support member 2 by observing the lighting 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 is always on, it means that the support member 2 is in the second position. At this time, the ejection device 10 is in the ejection state. The driver and passengers can take out the audio body 20 at this time, which can also facilitate the use of the ejection device 10 by the driver and passengers.

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

[0178] Through the above arrangement, the locking mechanism can lock the audio body 20 when the support 2 is in the first position, thereby limiting the movement of the audio body 20 relative to the support 2. This can ensure the stability of the audio body 20 placed on the support 2 and avoid collisions after the audio body 20 moves, thereby protecting the audio body 20.

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

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

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

[0182] Through the above arrangement, when the support member 2 moves to the first position, it means that the ejection device 10 is in a retracted state. If the control circuit board 5 receives the locking indication information at this time, it means that the audio body 20 has been placed on the support member 2, and the control circuit board 5 will control the locking structure to lock the audio body 20, so that the audio body 20 is fixed.

[0183] In some embodiments, Figure 7 , Figure 8 As shown, the ejection device 10 further includes a touch control member 7, which is connected to the housing 1. Fig.10 , Fig.11 As shown, Fig.10 for Figure 3 Another partial cross-sectional schematic diagram of the vehicle-mounted actuation assembly 100 is shown in FIG. Fig.11 for Fig.10 In the partially enlarged schematic diagram at A in the middle, the touch control member 7 is used to send locking instruction information to the control circuit board 5 when being touched by the audio body 20.

[0184] Through the above arrangement, when the audio body 20 touches the touch control element 7 , the touch control element 7 will send locking instruction information to the control circuit board 5 , so that the control circuit board 5 controls the locking structure to lock the audio body 20 .

[0185] Compared with setting a position sensor (such as an infrared sensor, etc.), sending locking instruction information by touching the control element 7 can simplify the structure of the ejection device 10 and reduce the volume of the ejection device 10, thereby facilitating the spatial arrangement of the ejection device 10.

[0186] Exemplarily, the touch control element 7 is a button 6 switch.

[0187] Exemplarily, the touch control element 7 is a micro switch.

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

[0189] In some embodiments, Figure 3 , Figure 4 As shown, the box body 30 is provided with an installation opening 302, and the installation opening 302 is communicated with the installation cavity 301. The ejection device 10 is connected to the outside of the box body 30 and covers the installation opening 302.

[0190] In some embodiments, a portion of the support member 2 can extend into the installation cavity 301 through the installation opening 302 , and the audio body 20 is placed on the portion of the support member 2 extending into the installation cavity 301 .

[0191] Through the above arrangement, part of the support member 2 can extend into the installation cavity 301 through the installation opening 302, thereby driving the sound body 20 in the installation cavity 301 to move. Compared with the ejection device 10 being arranged in the installation cavity 301, when the ejection device 10 is arranged outside the box body 30, there is a larger installation space outside the box body 30, which can facilitate the space arrangement of the vehicle-mounted actuating assembly 100.

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

[0193] In some embodiments, Figure 8 As shown, the housing 1 is provided with a second opening 17, and the second opening 17 is communicated with the mounting hole.

[0194] In this way, another part of the support member 2 can be arranged in the shell 1, and part of the support member 2 extends into the installation cavity 301 through the second opening 17 and the installation hole, so that the support member 2 can be shielded by the shell 1, thereby protecting the support member 2 and preventing the support member 2 from being damaged.

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

[0196] Through the above arrangement, when the support member 2 is located at the first position, the limiting member 23 can block the second opening 17 to prevent debris and the like from entering the first installation cavity 15 .

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

[0198] like Figure 4 As shown, along a direction perpendicular to the second direction, at least one first connection portion 201 is provided on the outer wall surface of the audio body 20 , and at least one second connection portion 303 is provided on the inner wall surface of the installation cavity 301 , and the second connection portion 303 is snap-connected with the first connection portion 201 .

[0199] Through the above arrangement, after the audio body 20 is placed in the installation cavity 301, the second connecting part 303 can be engaged with the first connecting part 201, so as to fix the audio body 20 in the installation cavity 301. This can further improve the stability of the audio body 20 placed in the installation cavity 301 and prevent the audio body 20 from being damaged after being bumped.

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

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

[0202] In this way, when the driver and passenger use the audio body 20 , the driver and passenger can take out the audio body 20 by taking the handle 202 , which makes it convenient for the driver and passenger to take the audio body 20 .

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

[0204] Through the above arrangement, since the handle 202 is arranged in the accommodating groove 203, the handle 202 will not affect the placement of the audio body 20 into the installation cavity 301, and after the audio body 20 is placed into the installation cavity 301, the box body 30 can cover the handle 202, thereby hiding the handle 202, which can improve the appearance effect of the vehicle 1000 when the audio body 20 is placed into the installation cavity 301.

[0205] In some embodiments, Figure 6 As shown, the box 30 is provided with a connector 304. The connector 304 is connected to the power supply device of the vehicle 1000. The audio body 20 is provided with a connection port. When the audio body 20 is placed in the box 30, the connector 304 is connected to the connection port.

[0206] In this way, when the audio body 20 is placed in the installation cavity 301, the audio body 20 can be charged by the power supply device of the vehicle 1000 to ensure that the audio body 20 has sufficient power when the driver and passengers use the audio body 20, thereby improving the driver and passengers' experience of using the vehicle-mounted actuator assembly 100.

[0207] In some examples, lubricating materials are provided on the inner wall surface of the installation cavity 301 and the outer surface of the audio body 20 .

[0208] By providing the lubricating material, the friction between the inner wall of the installation cavity 301 and the outer surface of the audio body 20 can be reduced, thereby making it easier for the driver and passengers to place the audio body 20 into the installation cavity 301 or take the audio body 20 out of the installation cavity 301.

[0209] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
