[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to explain the relevant utility model and are not intended to limit the utility model. The embodiments described herein are merely a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0027] See also Figure 1 and Figure 2 When the film 100 is processed, the pattern 110 on the film corresponds to the image area of the projection lens 300 ( Figure 2 The projection effect is static. If a motor 600 is added to rotate the film, while the projection lens 300 is fixed, dynamic projection can be achieved by adjusting the speed of the motor 600 and electronically controlling the on / off of the light source 200. However, due to factors such as the speed limit of the motor 600 and the control timing, the pattern 110 may flicker when switching between different patterns 110, affecting the viewing experience.

[0028] In order to solve the above technical problems, the present application provides a continuous dynamic film 100 projection system.

[0029] See also Figures 3 to 5 The continuous dynamic film 100 projection system includes a light source 200, a film 100, and multiple lenses 300, wherein the light source 200 is located on the inner side of the film 100; the film 100 includes multiple circles of projection frames arranged from the inside to the outside, and each circle of projection frames includes multiple projection frames around a circle; in the same circle of projection frames, a pattern 110 is set every at least one projection frame; multiple lenses 300 are located on the outer side of the film 100, and one lens 300 is set in a one-to-one correspondence with one circle of projection frames. When the film 100 rotates around its own axis, the light source 200, the corresponding projection frame, and the one lens 300 form a light path; multiple light paths form a projection.

[0030] In the present invention's continuous dynamic film 100 projection system, as the film 100 rotates about its axis, a light source 200, the corresponding projection frame, and a lens 300 form a single optical path; multiple optical paths form the projection. Because the projection is formed by multiple optical paths, and adjacent projection frames within the same circle are separated by at least one projection frame, the coordinated projection of multiple optical paths enables continuous projection, eliminating issues such as flickering of the pattern 110 and enhancing the user's visual experience.

[0031] It should be noted that in this example, the film 100 is divided into an inner side and an outer side, with the light source 200 positioned on the inner side and the lens 300 on the outer side. Furthermore, to improve projection clarity, a collimator 400 is positioned between the light source 200 and the film 100. The collimator 400 constrains the light from the light source 200 to a certain divergence angle before irradiating the film 100.

[0032] The light source 200 can be arranged separately or can be set on the circuit board 500 and integrated with the circuit board 500, which can reduce the number of parts and reduce the difficulty of assembly.

[0033] In some examples of the present application, the light source 200 includes lamp beads of at least one color, which may be LED lamp beads or incandescent lamps.

[0034] The film 100 can rotate about its own axis, thereby enabling different projection frames to be projected onto the film 100. In some examples, the film 100 is driven to rotate about its own axis by a motor 600. Because the film 100 is directly driven by the motor 600, the shaking caused by the installation of transmission parts can be reduced, thereby reducing the occurrence of jumps.

[0035] Specifically, the output shaft of the motor 600 is directly connected to the bracket 700 of the film 100. The rotating shaft and bracket 700 are interference-fitted or connected via an adhesive. The bracket 700 and film 100 are connected using a special-shaped hole or adhesive. Any structure that can drive the film 100 to rotate is within the scope of protection of this utility model.

[0036] In order to further reduce the volume of the system, the output shaft of the motor 600 passes through the circuit board 500 , thereby reducing the space occupied by the overlapping of the circuit board 500 and the output shaft of the motor 600 .

[0037] In some embodiments, the circuit board 500 is electrically connected to the light source 200 and the motor 600 to control the switching of the light source 200, brightness adjustment, speed of the motor 600, and selection of projection content.

[0038] It should be noted that the pattern 110 includes text and / or pictures. The number of projection frames can be two or more. The diagram discloses a two-circle structure, the outer circle 120 located on the outside and the inner circle 130 located on the inside. The outer circle 120 includes 16 projection frames ( Figure 4 Middle white circle), the inner circle 130 includes 8 projection frames ( Figure 4 center white circle).

[0039] The outer circle 120, starting from the 9 o'clock position and proceeding clockwise, is the first projection frame, the second projection frame, the third projection frame, the fourth projection frame, the fifth projection frame, the sixth projection frame, the seventh projection frame, the eighth projection frame, the ninth projection frame, the tenth projection frame, the eleventh projection frame, the twelfth projection frame, the thirteenth projection frame, the fourteenth projection frame, the fifteenth projection frame, and the sixteenth projection frame. The inner circle 130, starting from the 9 o'clock position and proceeding clockwise, is the first projection frame, the second projection frame, the third projection frame, the fourth projection frame, the fifth projection frame, the sixth projection frame, the seventh projection frame, and the eighth projection frame.

[0040] Each projection frame is provided with a corresponding pattern 110. The projection frames of the outer circle 120 are, from the first projection frame to the sixteenth projection frame, black frame, light carpet, "Princess Arrives," angel wings, black frame, black frame, black frame, black frame, "Princess Please Get In the Car," black frame. The projection frames of the inner circle 130 are, from the first projection frame to the eighth projection frame, black frame, light band one, light band two, light band three, light band four, black frame, light carpet, black frame, light band five, light band six, light band seven, black frame, light carpet, black frame, angel wings, black frame. See Table 1 for details:

[0041] Table 1

[0042]

[0043] Motor 600 drives film 100 to rotate counterclockwise (or clockwise). The outer ring 120 optical path is located 90° counterclockwise (at the 9 o'clock position) from the raised portion of film 100, and the inner ring 130 optical path is located 270° counterclockwise (at the 3 o'clock position) from the raised portion of film 100. When the product starts working, the first projection frame corresponding to the outer ring 120 optical path is a black frame (no pattern 110, opaque). As motor 600 rotates, pattern 110 on the film rotates to light band 1 and is projected onto a fixed area. The result is that light band 1 smoothly appears within the projection area. As the film rotates, light band 1 smoothly moves from one end of the projection area to the other. During this movement, light band 2 also slides into the projection area (the core innovation: continuous sliding), and then slides together with light band 1 to the other end of the projection area. This step is repeated, and light bands 3 and 4 appear in sequence, forming an animation effect in which one light band slides into four light bands within the projection area (completing the fifth projection frame in the diagram). The sixth projection frame is a black frame (no pattern 110, opaque), and the seventh projection frame is a light blanket, which slides into the projection area and fills the projection area, then remains lit. The inner area can be lit at the same time to complete the interaction, such as projecting a specified pattern 110 or text (here, the "Princess, Please Get in the Car" interaction is not limited to).

[0044] Then, motor 600 drives film 100 to rotate continuously, following the same steps as for the first to sixth projection frames, completing the eighth to thirteenth projection frames, achieving the projection effect (pattern 110 is not limited to the reference figure). The fourteenth projection frame is a black frame (no pattern 110, opaque). For the fifteenth projection frame, software controls motor 600 to rotate a fixed number of steps before illuminating the target projection area, now representing the "wings" pattern 110 (not limited thereto). After a predetermined dwell time, the inner circle 130 of the "wings" pattern 110 is illuminated, achieving an interactive animation effect. This completes the sixtieth projection frame (no pattern 110, opaque).

[0045] The above animation effects are simply to illustrate the effects of this patent (not limited to). Through the special continuous processing of the film 100, it can solve the current industry's actual poor effects such as actual smearing / flickering caused by multiple factors such as the motor 600 speed and electronic control.

[0046] The present application provides a vehicle including any of the above-mentioned continuous dynamic film projection systems 100. Since the above-mentioned continuous dynamic film projection system 100 has the above-mentioned beneficial effects, the vehicle including the continuous dynamic film projection system 100 has corresponding effects, which will not be described in detail here.
