[0062] The invention provides a story projector, which is used for picture and animation projection and can be applied to children's early education.

[0063] In the embodiment of the present invention, combined with Figures 1 to 3 As shown, the story projector includes a shell 1 and a material assembly 2. The shell 1 has an installation cavity 11 and is provided with a through opening 12 connected to the installation cavity 11; the tray 21 is provided with a carrier installation groove 213, and the tray 21 can be movably inserted into the through opening 12 so that the carrier installation groove is accommodated in the installation cavity.

[0064] In this embodiment, the shell 1 and the tray 21 can be made of plastic material. The shell 1 has an installation cavity 11, which is used to install the relevant parts of the story projector. The through hole 12 is an opening structure that runs through the inner and outer surfaces of the shell 1. The through hole 12 can allow the tray 21 to pass through. The thickness of the shell 1 can be large enough to make the inner wall of the through hole 12 wide enough, so that when the tray 21 slides in the through hole 12, the material component 2 has a large contact surface with the inner wall of the through hole 12, and the tray 21 is reliably supported and limited by the inner wall of the through hole 12.

[0065] The tray 21 is used for image projection. The carrier mounting groove 213 of the tray 21 can be used to install and accommodate material. The image carrier carries image content, and the image carrier can be projected to form an image screen. For example, the image carrier can be a film. The image content on the image carrier can be projected outward after being amplified by irradiation with a light source to form a projection image. The projection image can be a story picture, a story animation, etc. The entire projection process can be called story projection.

[0066] When the story projector is in use, the tray 21 is pulled outward from the housing 1, and the tray 21 can drive the carrier installation slot 213 through the opening, so that the carrier installation slot 213 is located outside the housing. At this time, a new carrier for story projection can be placed in the carrier installation slot 213, and then the tray 21 is pushed into the housing 1, so that the new carrier can enter the installation cavity 11, and the new carrier can be projected by the story projector. In this way, the projection of different images is realized, the projection content of the story projector is enriched, and the selectivity of the image material of the story projector is improved.

[0067] In one embodiment of the present invention, Figures 1 to 3 As shown, the story projector further includes a carrier 22 , and the carrier 22 is adapted to the carrier mounting groove 213 .

[0068] In this embodiment, the carrier 22 carries image materials for projecting images. The carrier 22 is detachably arranged in the carrier mounting groove 213 and is adapted to the size specifications of the carrier mounting groove 213 so that the carrier 22 can be detached and replaced, so that the story projector can replace and project different carriers 22, enrich the projection content of the story projector, and enhance the selectivity of the image materials of the story projector.

[0069] In one embodiment of the present invention, refer to Figure 5 , and combined with Figure 7 As shown, the story projector further includes a mounting seat 4 disposed in the mounting cavity 11 . The mounting seat 4 is provided with a slide groove 41 communicating with the through opening 12 . The tray 21 passes through the through opening 12 and is slidably disposed in the slide groove 41 .

[0070] In this embodiment, the mounting base 4 may be made of plastic material, and the slide groove 41 is a groove structure with a notch, and the notch of the slide groove 41 is arranged opposite to the through-port 12 and is in communication with the through-port 12. The tray 21 is in sliding contact with the bottom wall and side wall of the slide groove 41, and the bottom wall of the slide groove 41 may be provided with at least one rotatable roller, and the bottom surface of the tray 21 is in sliding contact with the roller, so that the tray 21 can slide more smoothly relative to the bottom wall of the slide groove 41. The slide groove 41 guides the sliding of the tray 21, and the bottom wall of the slide groove 41 has a good supporting effect on the tray 21, so that when the tray 21 is pulled out or pushed into the housing 1, the movement of the tray 21 is stable and not easy to deviate or shake.

[0071] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, a first limiting hole 411 is formed on the bottom wall of the slide groove 41, and a second limiting hole 211 is formed on the tray 21; the story projector also includes a limiting assembly 5, and the limiting assembly 5 includes a toggle member 51 and a limiting member 52, and the toggle member 51 and the limiting member 52 are spaced and movably arranged on the mounting seat 4, and one end of the toggle member 51 abuts against the limiting member 52; the toggle member 51 has an upward lifting state and a downward pressing state relative to the mounting seat 4, and when the toggle member 51 is in the upward lifting state, the limiting member 52 partially passes through the first limiting hole 411 and extends into the second limiting hole 211; when the toggle member 51 is in the downward pressing state, the limiting member 52 is disengaged from the second limiting hole 211.

[0072] In this embodiment, the toggle member 51 is used to toggle the limiting member 52 to move so that the limiting member 52 is inserted into the first limiting hole 411 and the second limiting hole 211, or the limiting member 52 is separated from the second limiting hole 211. The toggle member 51 can be rotatably connected to the inner wall of the installation cavity 11 so that the toggle member 51 can be lifted up or pressed down. When the toggle member 51 is in the lifted state, the limiting member 52 is inserted into the first limiting hole 411 and the second limiting hole 211, and the limiting member 52 abuts against the inner peripheral wall of the second limiting hole 211. The limiting member 52 stops the movement of the tray 21, so that the tray 21 cannot move in the through opening 12, thereby fixing the position of the carrier 22 in the installation cavity 11, which is convenient for projecting the image carrier 221 on the carrier 22. When the toggle member 51 is in the pressed state and the limit member 52 is disengaged from the second limit hole 211, the limit member 52 is located outside the second limit hole 211, and the limit member 52 does not stop the movement of the tray 21. The tray 21 can slide freely in the through opening 12 into the shell 1 or outside the shell 1, so that the tray 21 can be dragged out of the shell 1 and the carrier 22 on the tray 21 can be replaced.

[0073] In one embodiment of the present invention, Figure 3 and Figure 4As shown, the limiting component 5 also includes an elastic member 53 and a driving member 54 having an output shaft 541; the driving member 54 is arranged on the mounting seat 4, the limiting member 52 and the elastic member 53 are movably sleeved on the output shaft 541, and the elastic member 53 is limited between the limiting member 52 and the driving member 54; a stopper 521 is provided at one end of the limiting member 52, and the toggle member 51 abuts against the side of the stopper 521 facing away from the driving member 54.

[0074] In this embodiment, the elastic member 53 may be a spring, an elastic sleeve, etc., the driving member 54 may be a motor, the driving member 54 has a rotating shaft that can transmit and output power, that is, an output shaft 541, and the elastic member 53 is sleeved on the output shaft 541 of the driving member 54. The output shaft 541 of the driving member 54 may also be provided with a plurality of ribs, the limiting member 52 may be provided in a cylindrical shape, and the inner peripheral wall of the limiting member 52 may be provided with a plurality of rib grooves correspondingly, each rib is limited in each rib groove, and can slide along the rib groove, so that the limiting member 52 can be movably connected with the output shaft 541, and at the same time, the output shaft 541 of the driving member 54 can drive the limiting member 52 to rotate when it rotates.

[0075] One end of the limiting member 52 is provided with a stopper 521, which can be a circle of protrusions provided on the outer peripheral wall of the limiting member 52. One end of the toggle member 51 abuts against the stopper 521. When the wave member is pressed down, the toggle member 51 drives the limiting member 52 to move close to the driving member 54 through the stopper 521. At the same time, the limiting member 52 squeezes the elastic member 53, so that the elastic member 53 enters a compressed state, and the limiting member 52 is separated from the second limiting hole 211. When the toggle member 51 is lifted, the elastic member 53 squeezes and pushes the limiting member 52 to move along the output shaft 541 of the driving member 54 close to the second limiting hole 211 until the limiting member 52 is inserted into the second limiting hole 211, and the stopper abuts against the tray 21 for limiting.

[0076] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the carrier 22 is provided with a third limiting hole 222, and the third limiting hole 222 is arranged opposite to the second limiting hole 211; the inner peripheral wall of the third limiting hole 222 is provided with a tooth groove 2221, and the outer peripheral wall of the limiting member 52 is provided with a convex tooth 522, and the convex tooth 522 is spaced apart from the stop portion 521; when the toggle member 51 is in the lifted state, the limiting member 52 partially passes through the first limiting hole 411 and the second limiting hole 211, and extends into the third limiting hole 222, the convex tooth 522 is engaged with the tooth groove 2221, and the driving member 54 drives the limiting member 52 to drive the carrier 22 to rotate, so that the projection assembly 3 projects different image carriers 221 on the carrier 22.

[0077] In this embodiment, the carrier 22 is arranged in a circular or disc shape, and the carrier 22 is rotatably arranged on the tray 21. When the driving member 54 drives the limiting member 52 to rotate, the limiting member 52 drives the carrier 22 to rotate relative to the tray 21 through the protruding teeth 522 and the tooth grooves 2221, so that the multiple image carriers 221 on the carrier 22 move, because the point light source generally used to illuminate the image carrier 221 and project the image content on the image carrier 221 is fixedly arranged in the installation cavity 11, so when the carrier 22 rotates, the point light source can project different image carriers 221 on the carrier 22, and when the carrier 22 continues to rotate, the point light source 31 can project the image content on the multiple image carriers 221 to form an animation.

[0078] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the tray 21 is provided with a rotatable pressing block 212, one end of the pressing block 212 is located outside the shell 1, and the other end of the pressing block 212 abuts against the toggle member 51; one end of the toggle member 51 is rotatably connected to the mounting seat 4, and the other end of the toggle member 51 abuts against the limit member 52; the pressing block 212 rotates and drives the toggle member 51 to press down the limit member 52, so that the toggle member 51 enters a downward pressed state.

[0079] In this embodiment, the material of the pressing block 212 can be plastic, etc. The pressing block 212 can be rotatably connected to the tray 21 by a hole-shaft connection, or can be connected to the tray 21 by a torsion spring structure, so that the pressing block 212 can be reset after rotation. The pressing block 212 can abut against the bottom or top of the wave member. When the pressing block 212 is away from one end of the toggle member 51, the pressing block 212 can correspondingly lift or press down the toggle member 51. When the pressing block 212 is rotated and reset, the toggle member 51 is also reset accordingly. Because one end of the pressing block 212 is located outside the housing 1, it is convenient for the operator to press or reset the pressing block 212, so that the toggle member 51 enters a corresponding lifting or pressing state, and then the limiting member 52 is correspondingly inserted into the second limiting hole 211 of the tray 21 or detached from the second limiting hole 211, so that the tray 21 can be prevented from sliding out of the housing 1 when the story projector is in the projection playback and when the carrier 22 is replaced by non-manual operation, so as to ensure that the story projector performs reliable projection playback.

[0080] In one embodiment of the present invention, Figure 1 , Figure 3 as well as Figure 5 As shown, the story projector also includes a microphone 7 and a circuit module (not shown); the microphone 7 is disposed through the shell 1, and the circuit module is disposed in the installation cavity 11; the circuit module is electrically connected to the microphone 7 and the driving member 54, the microphone 7 is used to receive voice commands, and the circuit module is used to control the driving member 54 to run or stop running.

[0081] In this embodiment, when the microphone 7 receives the user's voice command, it can be analyzed through the circuit module and the driver 54 can be controlled to run or stop running accordingly. For example, after the user speaks the voice command "start playing" to the microphone 7, the circuit module controls the driver 54 to run, and the driver 54 drives the carrier 22 to rotate, so that the light source 31 irradiates the multiple image carriers 221 on the carrier 22, and the images or images on the multiple image carriers 221 are projected outward to form a continuous projection image and animation, thereby realizing the intelligent voice control function of the story projector. Of course, the intelligent voice control function of the story projector can also include a variety of control modes, such as controlling the driver 54 to drive the carrier 22 to stop rotating to maintain the current picture, or speeding up the rotation to fast forward the projection picture, or reversely rotating to return to the previous projection picture, etc.

[0082] In one embodiment of the present invention, Figure 1 , Figure 3 , Figure 5 as well as Figure 6 As shown, the story projector also includes a power supply 9 and a charging port (not shown); the power supply 9 is arranged on the mounting seat 4 and is electrically connected to the circuit module, and the power supply 9 is used to supply power to the circuit module; the charging port is passed through the shell 1 and is electrically connected to the power supply 9, and the charging port is used to charge the power supply 9.

[0083] In this embodiment, a slot body for accommodating the power supply 9 can be provided on the mounting seat 4, so that the power supply 9 can be accommodated and confined in the slot body, and the power supply 9 can be installed and fixed on the mounting seat 4. The charging port can be connected to an external power source to charge the power supply 9, so that the story projector can last for a long time and be used repeatedly. The power supply 9 is a battery, including but not limited to a lithium battery.

[0084] In one embodiment of the present invention, Figure 6 and Figure 7 As shown, the mounting seat 4 is provided with a receiving groove 45, and the receiving groove 45 is spaced from the slide groove 41; the groove wall of the receiving groove 45 and the inner wall of the mounting cavity 11 enclose a receiving cavity, and the shell 1 is provided with a sound outlet (not shown) connected to the receiving cavity; the story projector also includes a speaker 8 arranged in the receiving cavity.

[0085] In this embodiment, the accommodating cavity is an independent compartment in the installation cavity 11. The speaker 8 is arranged in the installation cavity 11, so that the vibration sound generation process of the speaker 8 is completely unaffected by other components in the story projector, and the quality of the sound output by the speaker 8 can be improved. The sound outlet connects the external environment and the accommodating cavity, and the sound outlet is used to propagate the sound emitted by the speaker 8 outward. A dustproof net can be arranged on the inner peripheral wall of the sound outlet to protect the speaker 8 from dust, prevent dust from entering the speaker 8 to generate electrostatic interference, so that the sound quality of the speaker 8 is not affected by dust, and at the same time, the service life of the speaker 8 is improved.

[0086] In one embodiment of the present invention, Figure 5 As shown, the carrier 22 is provided with a sensing hole 223, and the sensing hole 223 is spaced apart from the image carrier 221; the mounting seat 4 is provided with a sensing straight path 42, and the sensing straight path 42 is connected with the slide groove 41 and the sensing hole 223; the story projector also includes a first sensing member 43 and a second sensing member 44 provided on the mounting seat 4, and the first sensing member 43 and the second sensing member 44 are respectively provided adjacent to two intersections of the sensing straight path 42, and the first sensing member 43 and the second sensing member 44 are used for performing occlusion sensing on the carrier 22.

[0087] In this embodiment, the carrier 22 is located in the installation cavity 11, and when the limiting member 52 passes through the second limiting hole 211 on the tray 21 and is inserted into the third limiting hole 222 on the carrier 22, the driving member 54 can drive the limiting member 52 to drive the carrier 22 to rotate relative to the tray 21, so that the sensing hole 223 on the carrier 22 is set opposite to the sensing straight path 42.

[0088] The first sensing element 43 and the second sensing element 44 can be an infrared transmitter and an infrared receiver respectively. The infrared transmitter emits infrared light to the infrared receiver through the sensing channel 42 . When the sensing hole 223 on the carrier 22 is not arranged directly opposite to the sensing straight track 42, the carrier 22 blocks the above-mentioned infrared light.
