[0112] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0113] According to the first aspect of this application, referring to Figures 1 to 3 This application provides a media device 100 for a vehicle, which is used to implement media functions.

[0114] Specifically, the media functions of this application include signal interaction between the media device 100 and the user, using sound and light as carriers. For example, the media device 100 provides sound or images to the user; or, for example, the media device 100 captures sound or images. It should be noted that the media device 100 may only implement a single form of signal interaction, such as a speaker that only provides sound feedback; or the media device 100 may implement multiple forms of signal interaction, such as a tablet that simultaneously provides sound and images.

[0115] As an alternative, the signal interaction between the media device 100 and the user can also be based on other forms of carriers, such as force and heat. For example, the media device 100 can provide a touch-sensitive device such as a touchpad for the user to input signals; for example, the media device 100 can be a touch screen. Alternatively, the media device 100 can provide a temperature sensor to identify whether the user has entered the operating area of ​​the media device 100 based on the user's body temperature.

[0116] In other words, for the purposes of this application, the media device 100 can use force, heat, light, or sound as the carrier for signal interaction to interact with the user. The direction of signal interaction can be either from the user to the media device 100 or from the media device 100 to the user. The media device 100 can use only one of force, heat, light, or sound as the carrier for signal interaction to interact with the user; or the media device 100 can use a combination of force, heat, light, and sound to interact with the user.

[0117] Based on the above, the media device 100 of this application is more specifically used to realize signal interaction with the user, and the signal interaction is at least carried by sound and light.

[0118] As a specific implementation plan, media equipment 100 includes, but is not limited to, audio equipment, monitors, microphones, cameras, laser projectors, etc.

[0119] In some embodiments, refer to Figure 1 The media device 100 includes a transmission device 100a. The transmission device 100a is used to enable the media device 100 to transmit energy to an external device 30.

[0120] Optionally, the power transmission between the transmission device 100a and the external device 30 can be based on wired or wireless transmission. The external device can be a smartphone, computer, lighting device, etc.

[0121] Through the above technical solution, in addition to realizing the media function, by setting up the transmission device 100a, the media device 100 can supply power to other external devices, thereby expanding the application scenarios of the media device.

[0122] In some embodiments, the media device 100 is configured to have a coupled state coupled to the vehicle and a decoupled state decoupled from the vehicle. This allows the media device to be used independently of the vehicle through the coupled and decoupled states.

[0123] It is understood that the media device 100 is adapted to the vehicle 1, and the media device 100 has at least two working modes: one is that the media device 100 is separated from the vehicle 1, that is, the media device 100 is decoupled from the vehicle 1; the other is that the media device 100 and the vehicle 1 are at least physically connected, that is, the media device 100 is coupled to the vehicle 1.

[0124] In some embodiments, refer to Figures 1 to 5 The media device 100 includes: a media power supply 110.

[0125] The media power supply 110 provides power to the media device 100, enabling it to have sufficient battery life even when in a decoupled state, meeting usage time requirements in outdoor environments. The media power supply 110 may include rechargeable batteries, built-in supercapacitors, etc. The transmission device 100a is electrically connected to the media power supply 110 to enable the media device 100 to transmit power to the external device 30.

[0126] In some embodiments, refer to Figures 1 to 5 The media device 100 also includes a device body 140. The device body 140 has a power interface 124 for interfacing with a media power supply 110; wherein the media power supply 110 is detachably connected to the device body 140, and when the media power supply 110 is installed on the device body 140, it forms a connection with the power interface 124. This design facilitates the replacement of the media power supply 110, reduces charging waiting time, and provides convenience for users.

[0127] In some embodiments, refer to Figures 1 to 5 The transmission device 100a includes an external electrical interface 121. The external electrical interface 121 is connected to the media power supply 110 and is used to realize the transmission of electrical power between the media power supply 110 and the external device 30.

[0128] For example, the external electrical interface 121 may be a USB interface, a TYPEC interface, etc.

[0129] As an optional feature, the external electrical interface 121 is also configured to enable signal transmission between the media device 100 and the external device 30.

[0130] In some embodiments, refer to Figure 1 The transmission device 100a includes a wireless charger 122. The wireless charger 122 is connected to the media power supply 110 to enable wireless power transmission between the media power supply 110 and the external device 30.

[0131] It is understandable that the wireless charger 122 achieves wireless power transmission based on electromagnetic induction, radio waves, electromagnetic resonance, and other methods.

[0132] In some embodiments of this application, the transmission device 100a may include only the external electrical interface 121 or only the wireless charger 122; or, the transmission device 100a may include both the external electrical interface 121 and the wireless charger 122.

[0133] In some embodiments, refer to Figure 1 The media device 100 includes a conversion module 123. The conversion module 123 is configured to convert a first type of electrical energy from the media power supply 110 into a second type of electrical energy.

[0134] Optionally, the conversion module 123 may include an inverter 123a, a DC-DC converter, etc.

[0135] In a specific embodiment of this application, the conversion module 123 can convert the voltage of the media power supply 110 into the required output voltage. Both the first type of electrical energy and the second type of electrical energy can be direct current (DC). The voltage of the first type of electrical energy can be greater than or less than the voltage of the second type of electrical energy, depending on the load requirements. For example, the voltage of the media power supply 110 is 12V, and the conversion module 123 converts 12V to 5V.

[0136] Of course, the conversion module 123 can also convert the DC power of the media power supply 110 into AC power output.

[0137] In some embodiments, refer to Figure 1 The conversion module 123 includes an inverter 123a. The inverter 123a is used to convert the DC power from the media power supply 110 into AC power.

[0138] For example, when a connected AC device, such as an electric fan or projector, is detected, the media device outputs AC power to supply power.

[0139] In some embodiments, refer to Figure 5 The media device 100 also includes a first adapter electrical interface 130. The first adapter electrical interface 130 is used to enable the transmission of electrical power and / or signals between the media device 100 and the vehicle 1.

[0140] Specifically, the first adapter electrical interface 130 is configured to transmit electrical energy or signals with the vehicle 1 when the media device 100 is in a coupled state with the vehicle 1, and the first adapter electrical interface 130 is configured to disconnect the transmission of electrical energy from the vehicle 1 when the media device 100 is in a decoupled state with the vehicle 1, that is, to disconnect the physical connection.

[0141] In some other embodiments of this application, the same electrical interface can be used as both the external electrical interface 121 and the first adapter electrical interface 130 of this application.

[0142] In some embodiments, refer to Figure 4 and Figure 5 The media device 100 has a mounting slot 140a. Both the first adapter electrical interface 130 and the external electrical interface 121 are disposed within the mounting slot 140a. Thus, the mounting slot 140a provides protection for both the first adapter electrical interface and the external electrical interface 121.

[0143] In some embodiments, refer to Figures 2 to 5The media device 100 also includes a device body 140. The device body 140 has a mounting groove 140a, and a first adapter electrical interface 130 and an external electrical interface 121 are disposed in the mounting groove 140a.

[0144] In some embodiments, refer to Figures 2 to 5 The media device 100 also includes a cover plate 151. The cover plate 151 is movably connected to the device body 140 and is used to cover the mounting groove 140a.

[0145] It is understood that the movable connection between the cover plate 151 and the equipment body 140 includes rotational connection, sliding connection and other methods.

[0146] By adopting this solution, the cover plate 151 is used to protect the electrical interface when the media device 100 is in a decoupled state, while also serving an aesthetic purpose.

[0147] As a specific embodiment, the cover plate 151 has a first position and a second position relative to the outer shell. (Referring to...) Figure 4 When the cover plate 151 is in the first position, the cover plate 151 is attached to the equipment body 140 to isolate the mounting groove 140a from the outside; see reference. Figure 8 When the cover plate 151 is in the second position, the cover plate 151 avoids the positions of the first adapter electrical interface and the external electrical interface 121, so as to expose the first adapter electrical interface 130 and the external electrical interface 121.

[0148] It should be noted that the first position and the second position of this application can be different positions after the cover plate 151 is rotated relative to the media device 100 or different positions after the cover plate 151 is moved relative to the media device 100.

[0149] By adopting this solution, the cover plate 151 is used to protect the electrical interface when the media device 100 is in a decoupled state, while also serving an aesthetic purpose.

[0150] In some embodiments, refer to Figure 4 The media device 100 also includes an elastic element 152. The elastic element 152 is connected to both the cover plate 151 and the device body 140. The elastic element 152 is configured to allow the cover plate 151 to move to cover the mounting groove 140a. Thus, when the external force on the cover plate 151 is released, the cover plate 151 can automatically return to the first position.

[0151] In some embodiments of this application, reference is made to Figure 4The cover plate 151 is rotatably connected to the device body 140, and the elastic element 152 can be a torsion spring. Correspondingly, the vehicle 1 is provided with a push structure 211 that cooperates with the cover plate 151. When the media device 100 and the vehicle 1 are in a coupled state, the push structure 211 can push the cover plate 151 to rotate to expose the first adapter electrical interface 130, thereby realizing the connection between the media device 100 and the vehicle 1. When the media device 100 and the vehicle 1 are in a decoupled state, the elastic element 152 acts on the cover plate 151 to reset the cover plate 151 to the first position.

[0152] In some embodiments, refer to Figure 3 The media device 100 also includes a vibration damping pad 160. The vibration damping pad 160 is disposed on the outer wall of the media device 100 to achieve flexible contact between the media device 100 and the vehicle 1. With this design, when the media device 100 is in a coupled state with respect to the vehicle 1, it plays a role in buffering and absorbing sound.

[0153] The shock-absorbing pad 160 can be made of flexible materials such as rubber and silicone, and has elastic deformation capability.

[0154] In some embodiments, the media device 100 further includes a vibration unit. Multiple vibration units are provided and configured to provide different audio ranges, such as a first audio range, a second audio range, and a third audio range, wherein the first audio range is a high-frequency range, the second audio range is a mid-frequency range, and the third audio range is a low-frequency range.

[0155] In some embodiments of this application, the media device 100 has a device body 140, and the vibration unit is housed inside the device body 140, that is, the vibration unit and the device body 140 are an inseparable whole; or, the vibration unit can be embedded or placed in the device body 140, that is, these vibration units are detachably connected to the device body 140.

[0156] According to the second aspect of this application, referring to Figures 6 to 7 A media system 10 is provided, which includes the media device 100 and the vehicle adapter 200 described above.

[0157] The vehicle adapter 200 is connected to the vehicle 1 and is used to adapt the media device 100 so that the media device 100 has a coupled state and a decoupled state relative to the vehicle adapter 200.

[0158] When the media device 100 is in a coupled state, the media device 100 is connected to the vehicle adapter 200; when the media device 100 is in a decoupled state, the media device 100 is disconnected from the vehicle adapter 200.

[0159] Specifically, the vehicle adapter 200 is fixedly installed on the inner wall of the vehicle 1, for example, on one side of the trunk, without occupying the trunk or the entire vehicle space, so as to achieve better acoustic performance and entertainment functions in a limited space.

[0160] The vehicle adapter 200 primarily facilitates the transfer of electrical energy or signals between the media device 100 and the vehicle 1. Simultaneously, the vehicle adapter 200 also ensures that the media device 100 maintains a relatively fixed position relative to the vehicle 1. Therefore, in the coupled state, the media device 100 and the vehicle adapter 200 are physically connected. In the decoupled state, the physical connection between the media device 100 and the vehicle adapter 200 is severed, allowing the media device 100 to move independently without being constrained or interfered with by the vehicle adapter 200.

[0161] By adopting the above solution, the media device 100 of this application can be easily and seamlessly connected to the whole vehicle and work together, while also getting rid of the constraints and limitations of cable connections. It can be used not only in the car, but also in outdoor gatherings, travel, camping and other scenarios as a portable media device 100, which greatly expands its usage scenarios and convenience.

[0162] In some embodiments, refer to Figure 6 , Figure 7 and Figure 14 The vehicle adapter 200 includes a locking device 240. The locking device 240 is used to lock the media device 100 to the vehicle 1, that is, to lock the coupling state of the media device 100.

[0163] The locking device 240 includes a movable member 241. The movable member 241 is movably connected to the vehicle 1, allowing the movable member 241 to have a first state and a second state. For example, the movable member 241 can rotate, swing, slide, etc. relative to the vehicle 1.

[0164] In a first state, movable component 241 is adapted to lock vehicle 1 and media device 100, and in a second state, movable component 241 is adapted to unlock vehicle 1 and media device 100.

[0165] In the locking device 240 of this application embodiment, by providing a movable member 241 that is movably connected to the vehicle 1, the movable member 241 maintains the lock on the media device 100 and the vehicle 1 when it is in the first state, that is, it can lock when the media device 100 is in the coupled state, so as to avoid affecting the power or signal connection between the media device 100 and the vehicle adapter 200, thereby improving the stability requirements of the media device 100 when used in the vehicle 1; when the movable member 241 is in the second state, it releases the lock on the media device 100 and the vehicle 1, so that the media device 100 can be used independently without the vehicle 1, thereby meeting the usage requirements of different scenarios.

[0166] In some embodiments, the movable element 241 is configured such that, when in a first state, at least a portion of the movable element 241 stops in the path of the media device 100 leaving the vehicle 1.

[0167] Optionally, the stop of the movable part 241 on the media device 100 can be a method that interferes with the path of the media device 100 disengaging from the vehicle 1, such as a concave-convex fit or contact clamping.

[0168] In some embodiments, the movable element 241 is configured to, when in the second state, avoid the path of the media device 100 leaving the vehicle 1, thereby avoiding interference with the path of the media device 100 leaving the vehicle 1.

[0169] In some embodiments, refer to Figure 2 , Figure 7 and Figure 14 The active component 241 is configured such that, when in the first state, at least a portion of the active component 241 is embedded into the media device 100.

[0170] For example, the media device 100 is provided with a locking groove 140d that mates with the movable member 241. When the movable member 241 is in a first state, at least a portion of the movable member 241 is embedded in the locking groove 140d, thereby locking the media device 100 to the vehicle 1.

[0171] In some embodiments, the movable member 241 is rotatably connected to the vehicle 1 to lock the relative position of the media device 100 and the vehicle 1. This reduces the space required for the movable member 241 to switch between the first and second states, thereby reducing the overall volume of the locking device 240.

[0172] As an optional solution, refer to Figure 16 The locking device 240 further includes a rotating shaft 247. The rotating shaft 247 is rotatably connected to the movable member 241 and / or the vehicle 1, so that the movable member 241 can move to a first state and a second state.

[0173] It is understood that the movable part 241 is anti-rotationally connected (e.g., splined) or fixedly connected to the rotating shaft 247, while the vehicle 1 is rotatably connected to the rotating shaft 247; or, the movable part 241 is rotatably connected to the rotating shaft 247, while the vehicle 1 is anti-rotationally connected (e.g., splined) or fixedly connected to the rotating shaft 247; or, the movable part 241 and the vehicle 1 are rotatably connected to the rotating shaft 247 respectively, depending on the actual design requirements.

[0174] In some embodiments, refer to Figures 14 to 16 The locking device 240 further includes a first prime mover 242. The first prime mover 242 is dynamically coupled to the movable member 241 and is used to drive the movable member 241 to move between the first state and the second state.

[0175] When the movable component 241 is in the first state, the movable component 241 cooperates with the media device 100 to restrict the movement of the media device 100 relative to the vehicle 1; when the movable component 241 is in the second state, the movable component 241 disengages from the media device 100 to release the restriction on the media device 100.

[0176] For example, the first prime mover 242 may be an electric motor.

[0177] In some embodiments, the locking device 240 further includes a controller (not shown). The controller is electrically connected to a first prime mover 242 and is used to control the operation of the first prime mover 242 to switch between a first state and a second state of the movable element 241. Specifically, the controller may be a vehicle controller or a separate controller.

[0178] In some embodiments, refer to Figures 14 to 16 The locking device 240 further includes a first transmission mechanism 240a. The first transmission mechanism 240a is used to establish a power transmission between the first prime mover 242 and the moving part 241.

[0179] Optionally, the first transmission mechanism 240a can be a gear drive or belt drive.

[0180] In some embodiments, refer to Figures 14 to 16 The first transmission mechanism 240a includes: a driving member 244 and a driven member 245.

[0181] The driving member 244 is configured to move under the drive of the first prime mover 242; the driven member 245 is connected to the movable member 241 to drive the movable member 241 to move; the driving member 244 and the driven member 245 form a power coupling, thereby realizing the transmission of power.

[0182] Specifically, the driving member 244 is anti-rotationally connected to the output shaft of the first prime mover 242, and the driven member 245 is anti-rotationally connected to the moving member 241.

[0183] Optionally, the driving element 244 and the driven element 245 can be gears or pulleys, etc.

[0184] In some embodiments, refer to Figures 14 to 16 The driven member 245 is configured to provide torque to the movable member 241 so that the movable member 241 can rotate about a first axis C1.

[0185] It can be understood that the position of the first axis C1 coincides with that of the rotating shaft 247, that is, the rotating shaft 247 limits the movable part 241 to rotate around the first axis C1.

[0186] In some embodiments, refer to Figures 14 to 16 The driving element 244 is configured to rotate about a second axis C2 under the drive of the first prime mover 242; the second axis C2 is perpendicular to the first axis C1. This arrangement reduces the overall length of the first transmission mechanism 240a on the first axis C1 or the second axis C2, which is beneficial to the arrangement of the first transmission mechanism 240a.

[0187] As a specific plan, refer to Figures 14 to 16 The driving member 244 is configured to have a helical tooth 244a, and the driven member 245 is configured to have a driven tooth 245a that is directly or indirectly coupled to the helical tooth 244a.

[0188] Specifically, the helical tooth 244a can be a worm gear, and the driven tooth 245a can be a spur gear.

[0189] It is understood that the driven tooth 245a and the helical tooth 244a can directly mesh and transmit power, or the two can transmit power through at least one transmission member 246.

[0190] In some embodiments, refer to Figures 14 to 16 The first transmission mechanism 240a further includes a transmission member 246. The transmission member 246 is provided with at least one for establishing a power transmission between the driving member 244 and the driven member 245.

[0191] It is understandable that the transmission component 246 may be provided in one or more forms, which can be selected according to actual design requirements.

[0192] In some embodiments, refer to Figures 14 to 16 The transmission member 246 is configured to have a first transmission tooth 246a and a second transmission tooth 246b arranged coaxially. The helical tooth 244a meshes with the first transmission tooth 246a of one of the transmission members 246, and the driven tooth 245a meshes with the second transmission tooth 246b of one of the transmission members 246.

[0193] It is understood that when only one transmission member 246 is provided, the helical tooth 244a meshes with the first transmission tooth 246a of the transmission member 246, and the driven tooth 245a meshes with the second transmission tooth 246b of the transmission member 246; when multiple transmission members 246 are provided, along the power transmission path from the helical tooth 244a to the driving tooth, the second transmission tooth 246b of the previous first rotating member meshes with the first transmission tooth 246a of the next transmission member 246.

[0194] In some embodiments, refer to Figures 14 to 16 The number of teeth in the first transmission gear 246a is greater than the number of teeth in the second transmission gear 246b, and the number of teeth in the driven gear 245a is greater than the number of teeth in the second transmission gear 246b that meshes with it.

[0195] It is understandable that the tooth parameters of the helical tooth section 244a, the number of teeth of the driven tooth section 245a, and the number of teeth of each transmission component 246 can be selected according to the reduction ratio required by actual needs.

[0196] By adopting this scheme, the number of teeth of the first transmission gear 246a and the second transmission gear 246b are set so that the transmission component 246 can form a power transmission between the first prime mover 242 and the moving component 241, thereby playing the role of deceleration and torque increase.

[0197] In some embodiments, refer to Figures 7 to 9 The vehicle-mounted adapter 200 includes an adapter base 210. The adapter base 210 has an adapter space 210a for accommodating at least a portion of the media device 100. This allows the media device 100 to have a relatively defined mounting position on the vehicle 1. Furthermore, the adapter base 210 is provided with an opening allowing at least a portion of the media device 100 to enter the adapter space 210a.

[0198] Specifically, the movable part 241 is rotatably connected to the adapter base 210, thereby achieving a rotatable connection with the vehicle.

[0199] The adapter base 210 can be fixedly connected to the vehicle 1 by welding, threaded connection, snap-fit, or other methods, ensuring stable installation of the media device 100 on the vehicle 1, reducing the possibility of the media device 100 falling off the vehicle 1 under external impact, and improving the safety of the media device 100. In some embodiments of this application, the adapter base 210 is fixedly connected to at least one of the rear side panel 21, rear floor panel 22, etc. of the vehicle 1.

[0200] In some embodiments, the locking device 240 is disposed entirely outside the adapter space 210a to avoid interference with the movement path of the media device 100. The locking device 240 also includes a locking housing 243, which is fixedly connected to the side wall of the adapter base 210. This allows for modular installation of the locking device 240, improving assembly efficiency.

[0201] In some embodiments, refer to Figure 5 and Figure 9 The vehicle adapter 200 further includes a second adapter electrical interface 220. The second adapter electrical interface 220 is used to transmit electrical power and / or signals of the vehicle adapter 200.

[0202] The media device 100 includes a first adapter electrical interface 130. The first adapter electrical interface 130 is used to transmit electrical power and / or signals of the media device 100.

[0203] When the media device 100 is in a coupled state, the first adapter electrical interface 130 and the second adapter electrical interface 220 form an electrical connection for transmitting electrical power and / or signals. When the media device 100 is in a decoupled state, the first adapter electrical interface 130 and the second adapter electrical interface 220 disconnect the electrical connection for transmitting electrical power and / or signals.

[0204] By setting up the first adapter electrical interface 130 and the second adapter electrical interface 220, the vehicle adapter device 200 can establish a power and signal transmission path between the media device 100 and the vehicle 1.

[0205] As a specific embodiment, the second adapter electrical interface 220 is disposed on the movement path of the media device 100 in the adapter space 210a. Furthermore, the first adapter electrical interface 130 is disposed on the side facing the second adapter interface when the media device 100 moves in the adapter space 210a. It can be understood that the mating direction of the first adapter electrical interface 130 and the second adapter electrical interface 220 is parallel to the movement direction of the media device 100 when it moves in the adapter space 210a.

[0206] In some embodiments, refer to Figure 6 and Figure 7 The movable component 241 is configured to have at least a plurality of movement positions with a relative adaptation space 210a.

[0207] This approach ensures that the media device 100 can be stably positioned in the preset location within the adapter space 210a under coupled conditions, thus preventing damage to the internal circuitry caused by a sudden disconnection between the first adapter electrical interface 130 and the second adapter electrical interface 220.

[0208] In some embodiments, refer to Figure 9The side wall of the adapter base 210 is provided with a slot 210b communicating with the adapter space 210a. When the movable member 241 is in the locked position, part of the movable member 241 is inserted into the adapter space 210a from the slot 210b to lock the media device 100 in the adapter space 210a.

[0209] In some embodiments, two sets of locking devices 240 are symmetrically arranged on opposite side walls of the adaptation space 210a, which provides stable locking.

[0210] Specifically, the two opposite side walls of the adapter base 210 are respectively provided with the slots 210b, and the two different movable parts 241 are inserted into the adapter space 210a from the slots 210b on the opposite side walls when locked.

[0211] In some embodiments, refer to Figure 7 and Figure 8 The vehicle-mounted adapter 200 includes an ejection assembly 230. The ejection assembly 230 is used to drive the media device 100 to a decoupled state. At least a portion of the ejection assembly 230 is disposed in an adapter space 210a and has at least a plurality of movable positions relative to the adapter space 210a. The arrangement of the ejection assembly 230 enables the media device 100 to be driven to switch from a coupled state to a decoupled state.

[0212] In some embodiments, refer to Figure 8 and Figure 10 The launch component 230 includes: a pusher 231 and a second prime mover 232.

[0213] At least a portion of the pusher 231 passes through one inner wall of the adapter space 210a and is located within the adapter space 210a, and the pusher 231 is configured to push the media device 100 in an abutting manner; the second prime mover 232 is drive-coupled with the pusher 231 for driving the pusher 231 to move relative to the adapter base 210 along a preset direction D1. Specifically, the second prime mover 232 is electrically connected to the controller.

[0214] Optionally, the second prime mover 232 may be an electric motor, an electric push rod, a hydraulic cylinder, or a pneumatic cylinder, etc.

[0215] In some embodiments, refer to Figures 10 to 13 The component 230 also includes: a lead screw 233 and a lead screw nut 234.

[0216] The second prime mover 232 can be an electric motor, and the transmission screw 233 is configured to rotate under the drive of the second prime mover 232; the screw nut 234 is fitted onto the transmission screw 233 so as to move relative to the transmission screw 233 in a preset direction when the transmission screw 233 rotates. The pusher 231 is fixedly connected to the screw nut 234 so as to move with the screw nut 234.

[0217] As a specific solution, apart from the pushing component 231, the ejection assembly 230 is entirely positioned outside the adaptation space 210a to avoid interference with the movement path of the media device 100. The ejection assembly 230 also includes a pushing housing 235, which is fixedly connected to one side wall of the adaptation base 210. The pushing component 231 and the pushing housing 235 are slidably connected. The second prime mover 232 is fixedly connected to the pushing housing 235, and the transmission screw 233 is rotatably connected to the pushing housing 235. This allows for modular installation of the ejection assembly 230, improving assembly efficiency.

[0218] In some embodiments, refer to Figures 10 to 13 The launch component 230 also includes a second transmission mechanism 236. The second transmission mechanism 236 is used to establish power transmission between the second prime mover 232 and the transmission screw 233. Thus, the second transmission mechanism 236 serves to reduce speed and increase torque.

[0219] Specifically, the second prime mover 232 and the transmission screw 233 are located on the same side of the first reduction structure, and the output axis of the second prime mover 232 is parallel to the transmission screw 233, thereby reducing the space occupied by the push-out assembly 230.

[0220] Optionally, the second transmission mechanism 236 can be a gear drive or belt drive.

[0221] As a specific solution, the second transmission mechanism 236 includes multiple transmission gears 236a, which form a power transmission between the second prime mover 232 and the transmission screw 233. The reduction ratio can be designed according to actual needs.

[0222] In some embodiments, the vehicle adapter 200 is provided with a first guide structure; the media device 100 is provided with a second guide structure adapted to the first guide structure, so as to guide the media device 100 when it moves relative to the adapter base 210.

[0223] As an optional solution, refer to Figure 2 , Figure 7 and Figure 9The first guiding structure is configured to include an adapter guide rail 212 fixedly connected to or integrally formed on the inner wall of the adapter base 210, and the adapter guide rail 212 extends along a preset direction; the second guiding structure is configured to include an adapter groove 140b that mates with the adapter guide rail 212. Through the cooperation of the adapter guide rail 212 and the adapter groove 140b with the vehicle adapter device 200, the media device 100 can be guided into the adapter space 210a, facilitating the positioning and installation of the media device 100 in the adapter space 210a.

[0224] As another alternative, refer to Figure 3 and Figure 9 The first guiding structure is configured to include a guide post 213, which is disposed on the same inner wall of the adapter base 210 as the second adapter electrical interface 220. The first guiding structure is also configured as a guide groove 140c, which is disposed on the same outer wall of the adapter base 210 as the first adapter electrical interface 130. Through the cooperation of the guide post 213 and the guide groove 140c, the docking of the first adapter electrical interface 130 and the second adapter electrical interface 220 can be guided, improving docking accuracy.

[0225] To enable the coordinated operation of the ejection component 230 and the locking device 240, in some embodiments, reference is made to... Figure 7 and Figure 12 The vehicle adapter 200 also includes a position detection switch 250. The position detection switch 250 is used to detect the position of the media device 100 relative to the vehicle adapter 200.

[0226] In some embodiments of this application, the media device 100 contacts the position detection switch 250 when it moves to a preset position, thereby informing the vehicle adapter 200 whether the media device 100 has reached the preset position for achieving coupling. For example, the position detection switch 250 is mounted on the push housing 235.

[0227] In other embodiments of this application, the position detection switch 250 can detect the position of the media device 100 through a non-contact position sensor, which includes, but is not limited to, optical position sensors (such as infrared position sensors, laser position sensors), magnetic position sensors (such as Hall sensors), and pressure position sensors (such as pressure patch sensors).

[0228] In some embodiments, refer to Figure 6 and Figure 17 The media system 10 also includes a control switch 260. The control switch 260 is used for user operation of the vehicle adapter 200. Specifically, the control switch 260 is located next to the vehicle adapter 200 and matches the trunk side trim panel for user convenience.

[0229] For example, when the media device 100 is located in the vehicle adapter 200, and the user presses and holds (for example, for 2 seconds) the control switch 260, the control switch 260 outputs a high-level signal, the first prime mover drives the movable part 241 to release the lock on the media device 100, and then the second prime mover 232 drives the pusher 231 to move, thereby pushing the media device 100 to a preset removal position (obtained by the motor Hall signal); then the second prime mover 232 reverses, driving the pusher 231 back to its original position.

[0230] When the media device 100 is located within the vehicle adapter 200, and the user briefly presses the control switch 260, the operation is deemed invalid and no related action is performed.

[0231] When the media device 100 is located outside the vehicle adapter 200, and the user presses and holds or presses the control switch 260, it is determined to be an invalid operation and no related action is performed.

[0232] In some embodiments, the media system 10 further includes indicator lights. The indicator lights are used to provide status information for the vehicle adapter 200 and / or the media device 100. For example, different status information can be represented by the color, illumination duration, and flashing of the indicator lights.

[0233] For example, when the media device 100 is located in the vehicle adapter 200 and the user presses and holds (for example, for 2 seconds) the control switch 260, the media device 100 is pushed out and the indicator light shows a green light and flashes rapidly until it is pushed out to the preset removal position. Then the indicator light shows a solid green light (for example, for 1 second) and then turns off.

[0234] When the media device 100 is located within the vehicle adapter 200, and the user briefly presses the control switch 260, the indicator light will remain on red (for example, for 1 second) and then turn off.

[0235] When the media device 100 is located outside the vehicle adapter 200, and the user presses and holds or presses the control switch 260 for a long or short time, the indicator light will remain on red (for example, for 1 second) and then turn off.

[0236] When the media device 100 is detected to be placed back into the vehicle adapter 200, the indicator light on the movable part 241 flashes green rapidly during the locking process. After the locking is completed, the indicator light turns green continuously (for example, for 1 second) and then turns off.

[0237] In some embodiments of this application, the indicator light is integrated into the control switch 260.

[0238] According to the third aspect of this application, referring to Figure 18The present application provides a vehicle 1 that includes the media device 100 or media system 10 described above. The vehicle 1 has all the beneficial effects of the media device 100 or media system 10 described above, which will not be repeated here.
