[0002] With the continuous development of technology, screen projection technology has been increasingly widely used in people's lives and work. However, traditional screen projectors have some limitations in terms of functionality and performance. For example, the brightness of the projected image may not automatically adapt to different ambient lighting conditions, resulting in poor viewing quality; manual focus adjustment is required when the projection distance changes, which is cumbersome; insufficient heat dissipation may affect the stability and lifespan of the device; audio effects are not ideal and cannot be optimized according to different content and environments; and there is a lack of monitoring and intelligent control of the internal environment. Therefore, developing a more intelligent and higher-performing screen projector is of significant practical importance. Summary of the Invention

[0003] The purpose of this utility model is to provide an intelligent screen projector with multiple intelligent functions and optimized structural design, which can be widely used in education, office, home entertainment and other scenarios, to provide users with a convenient and high-quality screen projector experience, thereby solving the above-mentioned technical problems.

[0004] To achieve the above technical solution, the technical solution of this utility model is as follows: A smart projection device mainly consists of a projection device body, a first driving circuit, a driving board, a photomechanical engine, a heat dissipation component, a speaker box, a battery assembly, and a camera. The projection device body serves as the outer shell and supporting structure of the entire device, housing other key components. The first driving circuit and the driving board are electrically connected to each other, and the driving board is electrically connected to the photomechanical engine to drive and control the photomechanical engine. The heat dissipation component is in contact with the photomechanical engine to effectively dissipate the heat generated during its operation. The speaker box is used for audio output and is electrically connected to the first driving circuit.

[0025] Based on the above embodiments, the heat dissipation component 5 includes a heat sink 51; the heat sink 51 is provided with outwardly extending heat-conducting fins 52; one end of each of the three heat-conducting fins 52 is attached to the heat dissipation surface of the optical engine 4; a DC fan 53 is provided on one side of the heat sink 51; the airflow from the DC fan 53 passes through the heat sink 51 and flows out from the projection unit body 1. The heat sink, heat-conducting fins, and DC fan in the heat dissipation component work together to effectively solve the heat problem generated by the optical engine and the first drive circuit during operation. The outwardly extending heat-conducting fins on the heat sink can quickly conduct heat from the heat dissipation surface of the optical engine to the heat sink body, increasing the efficiency of heat transfer. The design of the three heat-conducting fins ensures the uniformity of heat conduction and avoids local overheating. The airflow from the DC fan passes through the heat sink, forming forced convection, which quickly carries heat out of the projection unit body, keeping the internal temperature of the device within a reasonable range. This efficient heat dissipation mechanism ensures that the optical engine and the first drive circuit maintain stable performance during long-term operation, preventing issues such as frequency reduction, crashes, or even damage due to overheating, thus improving the reliability and lifespan of the equipment.

[0026] Based on the above embodiments, the heat sink 51 is provided with an array of heat sink fins; a fixing plate is detachably provided on one side of the heat sink 51; and the other end of the heat sink 51 contacts the processing chip surface of the first driving circuit 2. Based on the above embodiments, the output end of the optomechanical engine 4 is provided with a lens; the optomechanical engine 4 is fixed to the housing 12 by a fixing plate. The array of heat sink fins on the heat sink further increases the heat dissipation area and improves heat dissipation efficiency. The detachable fixing plate facilitates the installation and removal of the heat sink, making equipment maintenance or heat sink replacement more convenient. The other end of the heat sink contacts the processing chip surface of the first driving circuit, enabling simultaneous heat dissipation of the processing chip and ensuring the stability of the processing chip during high-performance operation. This optimized heat sink structure not only improves the heat dissipation effect but also considers the utilization of internal space and the ease of component maintenance, allowing the heat dissipation component to play a more effective role in the entire device.

[0027] The output end of the optical engine 4 is equipped with a lens. The optical engine 4 is fixed to the faceplate 12 via a fixing plate. The lens focuses and adjusts the light, ensuring the clarity and accuracy of the projected image. The lens design effectively corrects light refraction and scattering, resulting in clear edges and vibrant colors in the projected image. The optical engine is fixed to the faceplate via the fixing plate, ensuring stable installation within the device and preventing vibration or displacement from affecting the projection effect during use. This stable installation method allows the optical engine to maintain an accurate projection angle and position during operation, guaranteeing the quality of the projected image. Whether displaying static images or playing dynamic videos, it provides users with a clear and smooth visual experience. Furthermore, the optical engine is electrically connected to the driver board, and under the coordination of the first drive circuit, it can accurately convert and output image signals according to different projection needs. Its spatial layout and functional coordination with other components within the projection unit (such as heat dissipation components, touch screen, and LCD screen components) have been optimized. For example, heat dissipation components can effectively dissipate the heat generated by the optical engine during operation, preventing overheating from affecting its performance; the touch screen and LCD screen components can work together with the projection function of the optical engine, allowing users to conveniently control the operation of the optical engine through the touch screen, such as adjusting parameters like the size and brightness of the projected image, thus achieving coordinated operation of the overall functions of the device and improving user convenience and satisfaction.

[0028] Based on the above embodiments, the main body 1 of the projection device is equipped with an intelligent environment sensing module 9, which is electrically connected to the first driving circuit 2. The intelligent environment sensing module 9 includes a light sensor, a distance sensor, and a temperature and humidity sensor. The light sensor is used to detect the ambient light intensity around the projection device and transmits the detection signal to the first driving circuit 2. The first driving circuit 2 automatically adjusts the brightness output of the optical engine 4 according to the light intensity. The distance sensor is used to detect the distance between the projection device and the projection screen. The first driving circuit 2 optimizes the projection focal length of the optical engine 4 based on the distance information. The temperature and humidity sensor is used to monitor the internal temperature and humidity of the projection device. When the temperature and humidity exceed the preset range, the first driving circuit 2 controls the heat dissipation component 5 to adjust the heat dissipation power and displays an abnormal temperature and humidity reminder on the projection device interface. The light sensor in the intelligent environment sensing module detects the ambient light intensity around the projection device in real time and transmits the signal to the first driving circuit. The first driving circuit automatically adjusts the brightness output of the optical engine according to the light intensity. In bright environments, such as daytime meeting rooms or living rooms, the optical engine automatically increases brightness to ensure a clear projected image. In dimly lit environments, such as when watching movies at night, it appropriately reduces brightness, saving energy and reducing eye strain for a more comfortable viewing experience. This light-adaptive function allows the projector to deliver optimal projection results under various lighting conditions, eliminating the need for frequent manual brightness adjustments. This enhances the device's intelligence and ease of use. A distance sensor detects the distance between the projector and the projection screen, and the first drive circuit optimizes the optical engine's projection focus based on this information. When the projector's position changes or the projection screen is replaced, the device automatically adjusts the focus to ensure the projected image remains clear and in focus. This feature avoids the tedious process of manual focusing, especially useful in large meeting rooms or classrooms. Users no longer need to frequently move around to adjust the projector's position and focus, saving time and effort and improving work efficiency. Meanwhile, the autofocus function ensures the clarity of the projected image, presenting a clear and sharp image whether projected onto a small screen at close range or a large screen at a distance. Temperature and humidity sensors monitor the internal environment of the projector. When the temperature or humidity exceeds the preset range, the first drive circuit controls the heat dissipation components to adjust their cooling power, and simultaneously displays an abnormal temperature and humidity warning on the projector interface. In high-temperature environments, such as prolonged use in summer or when the device is placed in a poorly ventilated area, the heat dissipation components will accelerate heat dissipation to prevent damage from overheating. In high-humidity environments, it reminds users to take precautions against moisture to avoid affecting the performance of electronic components. This temperature and humidity monitoring and control function effectively protects the internal components of the device, extends its lifespan, ensures stable operation under various environmental conditions, and improves the device's reliability and safety. At the same time, the abnormal temperature and humidity warning function allows users to take timely measures to ensure the normal use of the device.

[0029] When using the screen mirroring function: When the user transmits the content to be mirrored to the screen mirroring device via an external device (such as a computer, mobile phone, etc.), the first drive circuit receives the signal and controls the drive board to drive the optical engine. The optical engine converts the image signal into light, which is then projected through the lens at the output end. During projection, the focusing lens on the middle frame optimizes the light, making the projected image clearer and brighter. The optical engine generates heat during operation, which is conducted to the heat sink through the heat conduction plate. The heat sink fins on the heat sink increase the heat dissipation area, and the DC fan operates, causing air to flow through the heat sink and carry the heat away from the main body of the screen mirroring device, thereby achieving effective heat dissipation for the optical engine and the processing chip of the first drive circuit, ensuring stable operation of the device within the normal temperature range. The audio signal in the mirrored content is transmitted to the speaker box through the first drive circuit. The audio enhancement circuit in the speaker box automatically adjusts the audio frequency response through the equalizer according to the type of audio content (such as music, voice, etc.) to improve the sound quality. At the same time, the power amplifier intelligently adjusts the volume according to the ambient noise level to ensure that the user can hear the audio content clearly. The front and rear cameras operate under the control of the first drive circuit. When users take photos or record videos, the camera captures image or video data and transmits it to the first drive circuit for processing. In applications such as video conferencing, the camera transmits real-time images to the other party, enabling remote video communication. Furthermore, the camera can work with relevant software to achieve interactive functions such as gesture recognition, allowing users to control some functions of the projector through gestures. A light sensor detects the ambient light intensity in real time and transmits the signal to the first drive circuit. The first drive circuit automatically adjusts the brightness output of the optical engine based on the light intensity, ensuring optimal viewing under different lighting conditions. A distance sensor detects the distance between the projector and the projection screen, and the first drive circuit optimizes the projection focal length of the optical engine based on this distance information, ensuring the image remains clear and focused. A temperature and humidity sensor monitors the internal temperature and humidity of the projector. When the temperature or humidity exceeds a preset range, the first drive circuit controls the heat dissipation components to adjust their cooling power, and simultaneously displays an abnormal temperature and humidity warning on the projector interface, reminding the user to pay attention to the device's operating environment and ensuring the safe and stable operation of the device.
