[0002] To meet users' growing demands for enhanced experiences, vehicles are increasingly featuring advanced technology. High-end vehicles often incorporate 3D imaging devices, which achieve 3D imaging based on image changes and the persistence of vision. Currently, 3D imaging relies on the rotation of the imaging mechanism, which occupies a significant amount of space, resulting in bulky and space-consuming structures in existing 3D imaging devices.

The light emitted by the controllable light source is imaged on the imaging mechanism.

[0005] In one technical solution of this application, the light emitted by the controllable light source is imaged on the imaging mechanism to display a target object. The controller is used to divide the target object into two-dimensional image slices along the horizontal direction, encode and sort the two-dimensional image slices and store them, and send the two-dimensional image slices to the controllable light source for display in the encoded order.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Example 1 Reference Figure 1 and Figure 2 As shown, the imaging device of this application includes a fixed base 1, a controllable light source 2, a controller, a drive mechanism 3, a reflector bowl 19, a housing 16, and an imaging mechanism 4.

[0020] The controllable light source 2 includes a circuit board and an LED array mounted on the circuit board. The circuit board controls the LED array's light emission and color. The LEDs are RGB LEDs. The imaging device also includes a controller. A cable 29 is mounted on the drive base 13. The cable 29 is communicatively connected to the circuit board and the magnetic drive component 7, allowing the controller to send control signals to the circuit board and the magnetic drive component 7 via the cable 29. The controller then controls the magnitude of the electromagnetic force of the magnetic drive component 7 and the light emission and color of the LED array on the circuit board. Alternatively, the controllable light source 2 can also be a tablet, mobile phone, or other device capable of displaying two-dimensional images.

[0021] like Figure 1 and Figure 2As shown, the mounting base 1 includes a fixed base 12, a drive base 13, and a limiting base 14. The fixed base 12 and the limiting base 14 together form a mounting cavity 15. The drive base 13 and the controllable light source 2 are both disposed within the mounting cavity 15. Figure 4 As shown, the bottom of the fixing base 12 is provided with a wire harness hole 28 for threading cables 29. A mounting platform 23 is provided on the fixing base 12, extending upwards from the top surface of the fixing base 12. The circuit board is fixed to the mounting platform 23 by bolts or other fasteners. Several mounting platforms 23 are provided; preferably, three mounting platforms 23 are provided, with mounting slots 30 formed between adjacent mounting platforms 23. Figure 3 As shown, the drive base 13 includes a base plate 31 and four limiting plates 32. The four limiting plates 32 are arranged in a circular array about the axis of the base plate 31. The limiting plates 32 are snapped into the mounting slots 30 to limit the limiting plates 32, so that the drive base 13 can be installed at the corresponding angle by the fixing base 12, so that the cable 29 on the drive base 13 is set with the wire harness hole 28. In addition, the drive base 13 is fixed to the fixing base 12 by bolts and other fasteners.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a sliding rod 5 is provided on the fixed base 12. The sliding rod 5 extends in a straight line, preferably in a vertical direction. Several sliding rods 5 are provided, preferably four, arranged in parallel and rectangular arrangement. A sliding groove 6 is provided on the imaging mechanism 4. Several sliding grooves 6 are provided, preferably four, arranged in parallel and rectangular arrangement. The number of sliding rods 5 and sliding grooves 6 is the same. Along the extension direction of the sliding rod 5, the sliding grooves 6 are slidably disposed on the sliding rod 5, corresponding one-to-one, so that the linear sliding movement of the imaging mechanism 4 can be achieved through the cooperation of the sliding rods 5 and the sliding grooves 6, thereby reducing the volume of the imaging device and the space occupied by the imaging device. Figure 3 As shown, the bottom of the sliding rod 5 is fixed to the fixed base 12, and the top of the sliding rod 5 is provided with a first limiting end 24, which limits the sliding stroke of the imaging mechanism 4 on the sliding rod 5. The imaging mechanism 4 is an imaging mechanism made of transparent or semi-transparent materials, such as ordinary glass or frosted glass. Preferably, the imaging mechanism 4 uses frosted glass to balance sharpness and light mixing effect, thereby improving the imaging effect.

[0023] like Figure 3As shown, the driving mechanism 3 includes a magnetic drive component 7 and a magnetic sliding component 8. The magnetic sliding component 8 is an elastic component. The magnetic drive component 7 and the elastic component are magnetically coupled together, and the elastic component is driven to extend and retract by the electromagnetic force generated by the magnetic drive component 7. Specifically, the elastic component is a spring, which is a conductive spring, to facilitate magnetic coupling between the magnetic drive component 7 and the spring. Further, the spring includes a fixed part 9, a magnetic extension part 10, and a moving part 11 arranged sequentially. The magnetic drive component 7 is disposed on the driving base 13, the fixed part 9 is disposed on the magnetic drive component 7, the moving part 11 is connected to the imaging mechanism 4, and the magnetic drive component 7 is magnetically coupled to the magnetic extension part 10, so that the extension and retraction of the magnetic extension part 10 is controlled by the electromagnetic force generated by the magnetic drive component 7, thereby controlling the movement of the moving part 11 and thus controlling the sliding amount of the imaging mechanism 4. The magnetic drive component 7 is disposed on the limiting plate 32 of the driving base 13.

[0024] like Figure 2 As shown, the outer shell 16 is located on top of the limiting base 14, and the outer shell 16 and the limiting base 14 together form a receiving cavity 17. The imaging mechanism 4 is slidably disposed within the receiving cavity 17 in the vertical direction. The limiting base 14 is provided with a through hole 18, which connects the receiving cavity 17 and the mounting cavity 15. The fixing part 9 of the elastic member is located in the mounting cavity 15, and the moving part 11 of the elastic member is slidably disposed within the receiving cavity 17 in the vertical direction. The magnetic extension part 10 of the elastic member passes through the through hole 18. The top surface of the reflector 19 forms a second limiting end 25, and the sliding range of the imaging mechanism 4 is between the first limiting end 24 and the second limiting end 25.

[0025] like Figure 2As shown, the reflector bowl 19 includes a limiting part 20 and a light transmission part 21. A plurality of limiting protrusions 26 are provided on the drive base 13, arranged in a circular array around the center line of the drive base 13, with the outer edges of the protrusions 26 located on the same cylindrical surface. The inner wall of the limiting part 20 forms a limiting cylindrical surface 27. The limiting part 20 is fitted onto the limiting protrusions 26, and the outer edges of the protrusions 26 limit the limiting cylindrical surface 27 on the limiting part 20, thus achieving radial limiting of the limiting part 20, and consequently, radial limiting of the reflector bowl 19. In the vertical direction, the limiting part 20 is positioned between the limiting base 14 and the drive base 13 and is thus limited. The limiting base 14 and the drive base 13 achieve axial limiting of the limiting part 20, thereby achieving axial limiting of the reflector bowl 19. A through groove 22 is provided on the limiting base 14, which extends vertically through the limiting base 14. The light transmission section 21 is located inside the through groove 22, and the axis of the light transmission section 21 coincides with the axis of the through groove 22. The through groove 22 connects the mounting cavity 15 and the receiving cavity 17, so that the light emitted by the controllable light source 2 can pass through the light transmission section 21 and illuminate the imaging mechanism 4. The reflector bowl 19 is used to reflect the light emitted by the LED array upward to create a virtual image. The light transmission section 21 of the reflector bowl 19 is partially tilted, so that the light from the controllable light source 2 will diverge after being reflected by the reflector bowl 19, thereby forming a magnified virtual image above the reflector bowl 19 (on or near the frosted glass surface).

[0026] Working principle and process: The system slices the desired 3D image (target object) vertically to create several 2D image slices, which are then displayed using an LED array. The vertical sliding height of the frosted glass is matched to the 2D image slices created by the vertical slicing. When the frosted glass slides to the corresponding height, the LED array displays the corresponding 2D image slice, and the speed at which the LED array switches between displaying the image slices matches the vertical sliding speed of the frosted glass.

[0027] The controller sends control signals to the magnetic drive unit 7 via cable 29. The magnetic drive unit 7 controls the extension and retraction of the magnetic extension part 10 of the spring. The moving part 11 of the spring drives the frosted glass to perform high-speed, continuous up-and-down reciprocating motion above the reflector bowl 19. At the same time, the controller sends control signals to the circuit board via cable 29 to control the LED array to emit light. The light emitted by the LED array is a two-dimensional image slice. The two-dimensional image slice illuminates the reflector bowl 19. After being reflected by the reflector bowl 19, the light is no longer direct but becomes a beam of divergent light that shines upward. A magnified virtual image of the LED array is formed above the reflector bowl 19. When the light of the virtual image penetrates the frosted glass, the microstructure of the glass surface scatters the light in all directions, making the originally clear virtual image, which could only be seen at a specific angle, into a soft ball of light that can be seen from all angles. In this design, the light emitted by the LED array matches the height (speed) of the frosted glass as it slides linearly. The frosted glass's dwell time at each position during high-speed movement is extremely short (milliseconds). Due to the persistence of vision, the retina and brain cannot distinguish individual slices of imagery appearing at every instant. The brain automatically integrates a series of consecutive two-dimensional image slices received within a very short time, at different spatial heights, to construct a complete three-dimensional object image with continuous depth information—this is naked-eye 3D. The naked-eye 3D image presented in this application can display dynamic images, such as the movement of characters and changes in facial expressions and clothing. A character and its corresponding facial expressions and clothing form a set of 3D images. A character and its different facial expressions and / or different clothing form different sets of 3D images. Each set of 3D images is sliced ​​into several 2D image slices. The sliding height of each 2D image slice is matched with that of frosted glass. The colors of the LED light array corresponding to each set of 3D images are encoded, sorted and stored. The 2D image slices corresponding to each set of 3D images are sent to the LED light array. The LED light array displays the 2D image slices in sequence. Under the spectral changes of the LED light array, the preset character's actions, facial expressions and clothing can be displayed, so that the changes of light and shadow and the multi-dimensional interpretation of the virtual image form an immersive linkage, giving the character a vivid interactive expressiveness.

[0028] In one specific embodiment, the driving mechanism 3 is a linear motor (not shown in the figure). The output end of the linear motor slides in the vertical direction, and the imaging mechanism 4 is connected to the output end of the linear motor so that the linear motor drives the imaging mechanism 4 to slide in the vertical direction. The linear motor has high sliding accuracy, which can improve the sliding accuracy of the imaging mechanism 4.

[0029] In one specific embodiment, the drive mechanism 3 consists of four motors and lead screws (not shown in the figure). The motors are four rotary motors, and the lead screws include lead screw nuts and lead screw rods. The motors are mounted on the drive base 13, arranged in a rectangular pattern. There are four lead screw rods and four lead screw nuts, with one motor corresponding to one lead screw rod and one lead screw nut. The lead screw rods are mounted on the output shafts of the motors, and the lead screw nuts are mounted on the imaging mechanism 4. The lead screw nuts are driven by the lead screw rods. The four lead screw rods are arranged in parallel, as are the four lead screw nuts, and the output shafts of the four motors are also arranged in parallel. The controller controls the four motors to rotate synchronously. The output shafts of the four motors drive the four lead screw rods to rotate synchronously, and the four lead screw rods drive the four lead screw nuts to slide up and down synchronously, thus achieving linear sliding of the imaging mechanism 4. This rotating structure of motors and lead screws reduces design costs and allows for precise control of the sliding amount of the imaging mechanism.

[0030] Example 2 A loudspeaker assembly includes the imaging mechanism of Embodiment 1. The imaging mechanism includes a fixed base 1, a controllable light source 2, a driving mechanism 3, and an imaging mechanism 4. The controllable light source 2 and the driving mechanism 3 are both disposed on the fixed base 1. The imaging mechanism 4 is connected to the driving mechanism 3. The imaging mechanism 4 is slidably disposed on the fixed base 1 in the vertical direction. The light emitted by the controllable light source 2 is imaged on the imaging mechanism 4.

[0031] The speaker assembly includes a speaker base, a speaker, an imaging mechanism, and a controller. The imaging mechanism is positioned above the speaker base, while the speaker and controller are housed within the speaker base. Both the speaker and the imaging mechanism are communicatively connected to the controller. The controller controls the speaker to emit multimedia music and simultaneously controls the imaging mechanism to display corresponding multimedia dynamic 3D images. The multimedia music and the 3D images displayed by the imaging mechanism are synchronized to enhance the technological feel. The imaging mechanism, formed by linear sliding, has a compact structure and occupies little space, simplifying the speaker assembly's structure and reducing its footprint. Furthermore, the imaging mechanism can be slidably mounted on the speaker base in the vertical direction, allowing for raising and lowering of the imaging mechanism on the speaker base, creating a liftable speaker assembly and further enhancing its technological appeal.

The imaging mechanism 4 is slidably disposed on the fixed base 1 in the vertical direction. The light emitted by the controllable light source 2 is imaged on the imaging mechanism 4.

[0033] The vehicle includes a speaker assembly and an in-vehicle system. The speaker assembly includes a speaker base, a speaker, and an imaging mechanism. The imaging mechanism is positioned above the speaker base, while the speaker and controller are housed within the speaker base. Both the speaker and the imaging mechanism are communicatively connected to the in-vehicle system. The in-vehicle system controls the speaker to emit multimedia music and simultaneously controls the imaging mechanism to display corresponding multimedia dynamic 3D images. The multimedia music and the 3D images displayed by the imaging mechanism are synchronized to enhance the technological feel. The imaging mechanism, formed by linear sliding, has a compact structure and occupies little space, simplifying the structure of the speaker assembly and reducing its footprint in the vehicle. Furthermore, the imaging mechanism can be slidably mounted on the speaker base in a vertical direction, allowing for raising and lowering of the imaging mechanism on the speaker base, thus creating a liftable speaker assembly and further enhancing the vehicle's technological appeal.
