For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] Refer to Figures 1 to 3, the present utility model provides a sound-emitting, light-emitting, rotating projection device, which includes a main body 1, a projection panel 2, a light-emitting unit 3 and a sound-emitting unit 4;

[0034] The light-emitting unit 3 and the sound-emitting unit 4 are both arranged on the main body 1. The light-emitting unit 3 can emit light outward, and the sound-emitting unit 4 can emit sound;

[0035] The main body 1 includes a driving component 11. The projection panel 2 is in transmission connection with the driving component 11. After the driving component 11 is started, it can drive the projection panel 2 to rotate;

[0036] A plurality of hollowed-out projection parts 21 are uniformly arranged on the projection panel 2 along the circumferential direction. The hollowed-out projection parts 21 are preferably produced and manufactured by hollowing and grooving on the projection panel 2 to form patterns. Different hollowed-out projection parts 21 can form different patterns. The light beam emitted by the light-emitting unit 3 can be emitted from the hollowed-out projection parts 21. Since the specific projection contents of different hollowed-out projection parts 21 are different, while the projection panel 2 is rotating, it can project different hollowed-out projection parts 21, and project different patterns by means of rotating projection;

[0037] This device can not only emit light and project, but also perform rotating projection. With the cooperation of the light-emitting unit 3 and the sound-emitting unit 4, it can project a variety of hollowed-out projection parts 21, enriching the basic functions of the device and also enriching the selection of projected images, making the device more interesting and ornamental.

[0038] As an optional implementation manner, the driving component 11 is a motor gear assembly. A central hole 22 is penetrated through the inner side of the projection panel 2, and an annular rack 23 is arranged at the bottom of the central hole 22. The motor gear assembly is meshed with the annular rack 23. After the motor is started, it can drive the gear to rotate. The rotation of the gear can drive the annular rack 23 to rotate, thereby driving the projection panel 2 to rotate. The transmission method of the motor gear is more simple and practical, and has a good transmission effect.

[0039] As an optional implementation manner, the main body 1 further includes a lower shell 12, an upper shell 13, an upper seat 14 and a pressing member 15. The upper shell 13 is connected to the top of the lower shell 12, and the two enclose a receiving cavity, which can be used for installing and placing other parts. The projection panel 2 is located on the top of the upper shell 13. The upper seat 14 is movably connected to the top of the upper shell 13 and matches the step formed by enclosing the central hole 22 and the annular rack 23. The pressing member 15 is connected to the upper seat 14 and is movably connected to the upper shell 13;

[0040] The upper seat 14 and the pressing member 15 can limit and fix the projection panel 2. At the same time, the projection panel 2 is sleeved outside the upper shell 13. With the locking cooperation of a meson screw, the projection panel 2, the upper seat 14 and the pressing member 15 can form a loose fit with the upper shell 13, so that the projection panel 2, the upper seat 14 and the pressing member 15 can rotate synchronously relative to the upper shell 13. In this way, the projection panel 2 can achieve relatively smooth rotation;

[0041] It is preferably possible to provide stud holes on the lower shell 12 and on each component that needs to be connected inside the accommodation cavity, and provide studs on the upper shell 13. The studs on the upper shell 13 pass through the stud holes on the components and the stud holes on the lower shell 12 in sequence to form a connection.

[0042] As an optional implementation manner, a snap connection portion 141 is provided on the upper seat 14. The snap connection portion 141 is used to connect the shaped doll. With this setting, the basic functions of the device can be further enriched, making the device more beautiful and increasing the interest and ornamental value;

[0043] In this embodiment, it is preferably to provide a corresponding snap connection portion at the bottom of the structure of the shaped doll to form a snap connection between the two, which is easy to disassemble and assemble.

[0044] As an optional implementation manner, the light emitting unit 3 includes a plurality of LED lights. All the LED lights are evenly distributed in the circumferential direction. Each LED light can emit a variety of colors, and the colors can change. By using a plurality of evenly distributed LED lights and cooperating with the rotating projection panel 2, the multiple annular hollow projection portions 21 can be combined with the multiple LED lights to form a very rich color combination. In the area between adjacent LED lights, a mixed color can also be formed, which has stronger interest and ornamental value;

[0045] In this embodiment, the number of LED lights is preferably three. It is preferably possible to open holes on the upper shell 13 for installing the LED lights. The LED lights are preferably inclined so that the light is emitted obliquely upward.

[0046] As an optional implementation manner, the sound generating unit 4 is a speaker, and the speaker has a good sound generating effect.

[0047] As an optional implementation manner, a circuit board 5 is further included. The circuit board 5 is provided on the main body 1. The circuit board 5 is electrically connected to the driving component 11, the light emitting unit 3 and the sound generating unit 4 respectively. The circuit board 5 can control each unit and component. The control method here is a relatively conventional existing technology, so no further description will be made.

[0048] As an optional implementation manner, it further includes a main button 6. The main button 6 is arranged on the main body 1 and electrically connected to the circuit board 5. Through the control of the circuit board 5, pressing the main button 6 can make the device work normally.

[0049] As an optional implementation manner, it further includes a mute button 7. The mute button 7 is arranged on the main body 1 and electrically connected to the circuit board 5. Through the control of the circuit board 5, pressing the mute button 7 can turn off or turn on the sound, control the use of the mute mode. In the mute mode, the device can only perform the change of lights and the projection of patterns, which is convenient for lulling infants to sleep.

[0050] As an optional implementation manner, it further includes a battery box 8. The battery box 8 is arranged on the main body 1. The battery can be installed inside the battery box 8 and is electrically connected to the circuit board 5. The battery can provide power for the whole device.

[0051] The above are only the specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
