[0002] Currently, various projection devices are widely used in the field of image display, especially in education and entertainment. Story projectors, as portable projection devices, have attracted much attention due to their simple structure and ease of operation. Traditional story projectors mainly rely on mechanical transmission mechanisms to achieve directional projection of the film. Their transmission systems often use ordinary gear transmissions, but different types of gears have certain limitations in terms of transmission efficiency, torque transmission, and service life. For example, common bevel gears or spur gears are prone to problems such as poor meshing and large transmission errors during long-term high-speed operation, thus affecting the accurate display of the image and the projection effect. In addition, some projectors have loose or worn mechanical connections in their structural design, which restricts the stability and durability of the overall transmission system.

[0035] This invention proposes a story projector for projecting patterns on film onto a light-and-shadow carrier surface for display.

[0036] In the embodiments of this utility model, such as Figures 1 to 6 As shown, the story projector includes: a main body 10 and a film tray 40 carrying film. The main body 10 has an insertion hole 11 and a projection hole 12. The film tray 40 is movably inserted into the insertion hole 11.

[0037] The film disk 40 includes a housing 41 and a rotating disk 42 rotatably disposed within the housing 41. The film is disposed on the rotating disk 42 and is positioned corresponding to the projection hole 12.

[0038] The body 10 includes an optical component and a driving component disposed within the body 10. The optical component emits light toward the projection hole 12, and the film is located between the optical component and the projection hole 12.

[0039] The drive assembly includes a drive motor 31, a drive gear 32 mounted on the drive shaft of the drive motor 31, and a driven gear 421 meshing with the drive gear 32 on one side of the rotating disk 42. Both the drive gear 32 and the driven gear 421 are face gears.

[0040] The main body 10 is the projector's core structure for projection, including optical and driving components. The socket 11 is used to mount the film disc 40. It should be noted that the film disc 40 is movably inserted into the socket 11, facilitating user replacement. The film disc 40 consists of a housing 41 and a rotating disk 42 rotatably mounted within the housing 41. The film is fixedly mounted on the rotating disk 42, and the pattern area of ​​the film accurately corresponds to the projection hole 12, ensuring that the pattern on the film periodically appears in front of the projection hole 12 when the rotating disk 42 rotates.

[0041] Additionally, a recessed groove 14 is formed in the body 10 corresponding to the insertion hole 11. The recess 14 guides the installation and positioning of the film disc 40, ensuring that the film disc 40 can be precisely inserted into the body 10 and correctly aligned with the optical components. This recess 14 design effectively prevents misalignment during film disc 40 installation, improving operational accuracy and stability. The depth and shape of the recess 14 are optimized to ensure stable installation of the film disc 40 while allowing for quick removal by the user during disassembly.

[0042] The optical component is the light-emitting element of the projector. It is installed within the main body 10, with its light emission direction aligned with the projection aperture 12. The film is located between the optical component and the projection aperture 12. When the optical component emits light, the light passes through the film and is projected onto the light-and-shadow carrier surface, forming a clear and uniform pattern display. Specifically, the optical component includes at least one light source 21 and multiple lenses, which are arranged at intervals between the light source 21 and the projection aperture 12. The arrangement of multiple lenses effectively adjusts the refraction path of the light, ensuring that the light emitted by the light source 21 can pass uniformly and clearly through the projection aperture 12 onto the film, forming a stable image projection. The arrangement and spacing of the lenses are precisely designed to ensure that the light does not suffer excessive light loss or distortion during transmission, thereby improving the quality and clarity of the projection effect.

[0043] The lens may include an imaging lens 221, an adjustment lens 222, and a wide-angle lens 223 arranged sequentially along the projection direction of the film. The imaging lens 221 collects the effective pattern light spot passing through the film, thereby forming a real image pattern that is projected onto the adjustment lens 222. The adjustment lens 222 reshapes and corrects the real image before projecting it onto the wide-angle lens 223. The wide-angle lens 223 magnifies the adjusted real image pattern and projects it onto the light-and-shadow carrier surface, thus presenting a clear and magnified pattern effect on the light-and-shadow carrier surface. By setting multiple lenses with different functions, the clarity of the pattern projected by the projection device is effectively improved, thereby effectively improving the practicality of the projection device.

[0044] In addition, the optical components also include a mounting tube 18 and an adjustment knob 19 located at the projection hole 12. The mounting tube 18 is used to fix the imaging lens 221, the adjustment lens 222, and the wide-angle lens 223 so that the imaging lens 221, the adjustment lens 222, and the wide-angle lens 223 are always located on the same axis, so as to avoid the relative position of the imaging lens 221, the adjustment lens 222, or the wide-angle lens 223 changing when the projection device is subjected to external force, thereby affecting the projection effect of the projection device. The adjustment knob 19 is movably connected to the mounting tube 18, and the focusing knob can drive the mounting tube 18 to move back and forth along the axial direction when rotated to adjust the size of the projected pattern of the projector.

[0045] The drive assembly includes a drive motor 31 and a drive gear 32 mounted on its output shaft. A driven gear 421 meshes with the drive gear 32 on one side of the rotating disk 42. Both the drive gear 32 and the driven gear 421 are face gears. When the film disk 40 is inserted into the body 10 through the insertion hole 11, the rotating disk 42 and the motor shaft of the drive motor 31 form a central connection. When the drive motor 31 starts, the meshing of the drive gear 32 and the driven gear 421 drives the rotating disk 42 to rotate smoothly, allowing the film mounted on the film disk 40 to pass continuously and evenly through the projection hole 12, thus displaying dynamic story patterns. Simultaneously, the meshing of the face gears effectively reduces the installation space of the drive structure, improving the projector's practicality and user experience.

[0046] This utility model's story projector includes a projector body 10 and a film disk 40 for carrying film. The projector body 10 has an insertion hole 11 and a projection hole 12. The film disk 40 is movably inserted into the insertion hole 11, thereby fixing the film onto a rotating disk 42 and corresponding to the position of the projection hole 12. The projector body 10 contains an optical component and a drive component. The light emitted by the optical component travels along a fixed path through the film disk 40 and illuminates the film, and is then output through the projection hole 12 to achieve the projection display of the pattern. The drive component includes a drive motor 31 and a drive gear 32 mounted on its drive shaft. The drive gear 32 meshes with a driven gear 421 (both are face gears) provided on the side of the rotating disk 42 to ensure that the rotating disk 42 rotates evenly and accurately under the drive. Through the above structural design, the film disc 40 can remain stable after being installed inside the projector body 10 and rotate smoothly under the action of the drive component. Even when the device is subjected to external vibration or tilting, the pattern on the film can still maintain accurate alignment with the optical components and projection aperture 12, thereby ensuring the clarity, continuity, and stability of the projected pattern. Therefore, this story projector not only facilitates the replacement and installation of the film disc 40, but also significantly improves the overall projection effect through precise drive and optical system design, thereby greatly enhancing the practicality and user experience of the device in actual applications.

[0047] Furthermore, such as Figures 1 to 6As shown, a guide groove 411 is formed on the outer wall of the housing 41, and the driven gear 421 is located within the guide groove 411. In this embodiment, the guide groove 411 extends from the driven gear 421 towards the periphery of the housing 41 and penetrates one side of the housing 41, thereby forming a channel for the movement of the driving gear 32. When the film disc 40 is inserted into the projector body 10, the driving gear 32 can move from the opening on one side of the housing 41 along the guide groove 411, gradually entering the guide groove 411 and achieving precise meshing with the driven gear 421. This structural design ensures the smoothness of the gear meshing process, improves the stability of the transmission components, and avoids gear misalignment or jamming caused by assembly errors or improper operation. In addition, the guide groove 411 allows the driving gear 32 to move along a preset path, simplifying the installation operation of the film disc 40 and improving the user experience and the practicality of the device.

[0048] Furthermore, such as Figures 1 to 6 As shown, the projector also includes an audio component located within the main body 10 and an electronic tag 43 located on the film reel 40 and electrically connected to the audio component. The audio component includes a control board 51, an identification module 52 for identifying the electronic tag 43, a storage medium pre-stored with audio corresponding to the electronic tag 43, and a speaker 54 electrically connected to the control board 51. In this embodiment, the audio component is used to identify the electronic tag 43 and play the corresponding audio content according to the information stored in the electronic tag 43. The stored content of the electronic tag 43 corresponds to the pattern content on the film reel, so that while the projector is playing the image, it can simultaneously output sound effects or narration content that matches the image. This design not only enhances the immersiveness of the projection effect but also helps users understand the projected content more intuitively, improving the interactivity and practicality of the projector. In addition, through the automatic identification function of the electronic tag 43, the projector can automatically load the corresponding audio content according to different film reels 40, avoiding the tedious operation of manually selecting audio by the user and improving ease of use.

[0049] Furthermore, the identification module 52 detects and reads the information in the electronic tag 43 and transmits the read information to the control board 51. The control board 51 parses the information in the electronic tag 43 and extracts the audio data corresponding to the electronic tag 43 from the storage medium. Subsequently, the control board 51 controls the speaker 54 to play the corresponding audio content, enabling the projector to synchronously output sound effects or narration content matching the film pattern. This design ensures the accuracy and automation of audio playback, improving the user's viewing experience. In addition, the storage medium can pre-store multiple sets of audio data according to different film discs 40 to adapt to the needs of different projection content, further enhancing the practicality and interactivity of the projector.

[0050] In addition, a reset mark is provided on the rotating disk 42. An identification module for identifying the reset mark is provided in the body 10. The identification module is electrically connected to the control board 51, and the drive assembly is electrically connected to the control board 51, so that when the identification module identifies the reset mark, the control board controls the drive assembly to drive the rotating disk 42 to rotate to the initial position of the film pattern.

[0051] Furthermore, such as Figures 1 to 6 As shown, a mounting shell 60 is provided on the inner wall of the main body 10 corresponding to the position of the insertion hole 11. The film tray 40 passes through the insertion hole 11 and is installed inside the mounting shell 60. At least one spring piece 62 is provided inside the mounting shell 60, and the spring piece 62 movably abuts against the outer wall of the film tray 40. In this embodiment, the mounting shell 60 is fixed to the inner wall of the housing 41 and is positioned corresponding to the position of the insertion hole 11 to ensure that the film tray 40 can be stably and accurately installed inside the main body 10.

[0052] The spring clip 62 is used to fix the film tray 40. Specifically, the spring clip 62 is located on the inner wall of the mounting housing 60 and partially protrudes from the inside of the mounting housing 60. When the film tray 40 is inserted into the mounting housing 60, the spring clip 62 provides a continuous clamping force through its elasticity, thereby effectively preventing the film tray 40 from loosening or shifting during use, ensuring that the film tray 40 maintains a stable position in the projector, and avoiding instability or image shift caused by vibration or external force.

[0053] Multiple springs 62 can be configured to provide greater clamping force to the film disc 40.

[0054] Furthermore, such as Figure 1 As shown, the side wall of the main body 10 is also provided with multiple storage slots 13 for storing film trays 40. In this embodiment, the design of the storage slots 13 allows users to conveniently store multiple film trays 40, and each storage slot 13 has an appropriate size to ensure that the film trays 40 can be placed stably without slipping or falling. The number and position of the storage slots 13 are carefully arranged to facilitate users to quickly retrieve and place different film trays 40, improving the practicality and convenience of the device.

[0055] Furthermore, such as Figures 1 to 5As shown, the main body 10 also includes a handle 15, and a movable groove 16 is formed on the outer wall of the main body 10, within which the handle 15 is movably disposed. In this embodiment, the design of the handle 15 allows the user to adjust its position as needed, providing a convenient carrying method and allowing the handle 15 to be stored in the movable groove 16 when not in use, avoiding excessive space occupation. The movable groove 16 ensures the stability of the handle 15 and prevents it from accidentally falling off or shifting during use. This design increases the product's portability while improving safety and stability during use.

[0056] Furthermore, such as Figures 1 to 5 As shown, the main body 10 also includes a triggering mechanism, which includes a push rod 72 and a top rod 71. The main body 10 has a mounting hole, and the mounting housing 60 has a movable hole. The top rod 71 passes through the movable hole and abuts against the film disc 40. A movable roller 714 is provided at the end of the top rod 71 near the push rod 72. The push rod 72 passes through the mounting hole, and an abutting block 721 is provided at the end of the push rod 72 near the movable roller 714. The side of the abutting block 721 that abuts against the movable roller 714 is inclined. In this embodiment, the triggering mechanism is used to automatically release or push the film disc 40 when the user needs to replace or adjust it. Specifically, the push rod 72 pushes the top rod 71, causing the movable roller 714 on the top rod 71 to contact the film disc 40, thereby causing the film disc 40 to be pushed outward or released under the action of the push rod 72. The inclined design of the abutment block 721 ensures that when the push rod 71 is subjected to thrust, the movable roller 714 can smoothly contact the film tray 40, thereby guaranteeing the safe movement and release of the film tray 40. Simultaneously, the coordinated design of the push rod 72 and the push rod 71 effectively controls the operation of the film tray 40, ensuring stable equipment operation and preventing inaccurate positioning or displacement of the film tray 40 due to improper operation.

[0057] Furthermore, such as Figures 1 to 5 As shown, the bottom of the mounting housing 60 is provided with an operating space 80, and the movable roller 714 and the abutment block 721 are located in the operating space 80;

[0058] An operation button 723 is provided at the other end of the push rod 72 relative to the abutment block 721. The operation button 723 is located inside the mounting hole. A first return spring 724 is sleeved on the outer wall of the push rod 72. One end of the first return spring 724 abuts against the outer wall of the operating space 80, and the other end abuts against the operation button 723. In this embodiment, the operating space 80 facilitates the free movement of the push rod 72 and the top rod 71, while ensuring that the movable roller 714 and the abutment block 721 can work smoothly together within the mounting housing 60. Specifically, the design of the operating space 80 ensures that the movement of the triggering mechanism is not interfered with by other components, providing sufficient space for the push rod 72, the top rod 71, and their accessories to make appropriate displacements. When the triggering mechanism is activated, the push rod 72 pushes the top rod 71 through the operating space 80, thereby making the contact between the movable roller 714 and the film disc 40 more precise. The design of the abutment block 721 and the movable roller 714 can effectively avoid jamming caused by imbalance or excessive resistance, ensuring that the film tray 40 is pushed or released smoothly and quickly, effectively improving the stability and durability of the equipment.

[0059] The operation button 723 is designed to allow users to easily operate the push rod 72 by applying external pressure. Specifically, when the user presses the operation button 723, the push rod 72 is subjected to external force, pushing the push rod 71 towards the film disk 40, thereby triggering and operating the film disk 40.

[0060] The design of the first return spring 724 serves an automatic reset function. When the user stops pressing the operation button 723, the first return spring 724 uses its elastic force to reset the push rod 72, ensuring that the push rod 72 automatically returns to its initial position without external force. This ensures that the equipment is in a normal and stable state after each operation, avoiding the equipment being in an abnormal position for a long time due to improper operation.

[0061] Through the coordinated action of the first reset spring 724 and the operation button 723, this embodiment can achieve smooth advancement and reset of the push rod 72, enhancing the operational comfort and stability of the equipment, while improving the user experience of the equipment.

[0062] Furthermore, such as Figures 1 to 5As shown, a limiting seat 81 is provided on the inner wall of the operating space 80 corresponding to the position of the movable hole. A top plate 711 is provided at one end of the push rod 71 that abuts against the film tray 40, and a limiting plate 712 is provided at the other end. The limiting plate 712 is located inside the limiting seat 81. A second return spring 713 is sleeved on the outer wall of the push rod 71. One end of the second return spring 713 abuts against the bottom of the mounting shell 60, and the other end abuts against the limiting plate 712. In this embodiment, the cooperative design of the limiting seat 81 and the limiting plate 712 can effectively limit the displacement range of the push rod 71, preventing instability or jamming caused by excessive movement of the push rod 71 during operation. Specifically, when the push rod 71 contacts the film tray 40 during pushing, the top plate 711 pushes the film tray 40 to a suitable position, while the limiting plate 712 ensures that the movement of the push rod 71 will not exceed the set range, thereby avoiding damage to the equipment or operational errors.

[0063] The function of the second return spring 713 is to automatically return the push rod 71 to its initial position when the force on it is no longer applied, ensuring that the equipment is in normal working condition after each operation. The elastic design of the return spring also ensures smooth operation. When the push rod 71 is pushed towards the film tray 40 and released, the return spring provides sufficient restoring force to quickly return the push rod 71 to its original position, ensuring consistency and stability in each operation. The limit seat 81 also prevents excessive movement of the push rod 71, further improving the reliability and service life of the system.

[0064] Furthermore, such as Figures 1 to 5 As shown, the inner wall of the operating space 80 is provided with a limiting groove 82, and the bottom of the abutment block 721 is provided with limiting blocks 722 on opposite sides. The limiting blocks 722 slide within the limiting groove 82. In this embodiment, the design of the cooperation between the limiting groove 82 and the limiting blocks 722 can precisely control the movement range of the abutment block 721, ensuring stable and controllable operation of the push rod 72 and the push rod 71. Specifically, the sliding of the limiting block 722 within the limiting groove 82 restricts the range of motion of the abutment block 721, thereby effectively preventing excessive offset or misalignment of the abutment block 721 during operation, ensuring that the movement trajectory of the push rod 72 and the push rod 71 remains within a predetermined range, and improving operational accuracy.

[0065] This design allows the abutment block 721 to slide smoothly within the limiting groove 82 during operation, preventing jamming or damage caused by excessive movement. This optimized structure ensures smooth operation and effectively improves the durability and long-term stability of the equipment. Furthermore, the mating structure between the limiting groove 82 and the limiting block 722 makes assembly of this component more precise, avoiding excessive or insufficient deviations, thereby further ensuring the accuracy and reliability of the entire device.

[0066] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
