[0037] Example

[0038] Reference Figures 1 to 5 As shown, this application embodiment provides a rugged mobile phone with an autofocus projector, including a mobile phone body and a projector, the projector being mounted on the mobile phone body; the specific resolution of the projector may include 480P / 540P / 720P / 1080P, etc. The projector includes: a main control board 1 and a projector body 2 electrically connected to the main control board 1, a focusing component 3, and a heat dissipation component 4;

[0039] The projector body 2 includes a main optical path module 21 and an extended optical path module 22. The main optical path module 21 is provided with a projection window 211, and the extended optical path module 22 is provided with one or more light sources 221. The extended optical path module 22 is connected to the main optical path module 21, forming a projection optical path from the light source 221 to the projection window 211. Specifically, the light beam emitted by the light source 221 is conducted to the main optical path module 21 via the extended optical path module 22 and projected through the projection window 211.

[0040] In one optional implementation, the main optical path module 21 and the extended optical path module 22 extend along non-collinear directions and are interconnected to jointly enclose an approximately L-shaped bent projection optical path. This makes the projector structure more compact, extends the optical path within a limited space, reduces space occupation, optimizes the overall spatial layout of the projector, and the appropriate extension of the optical path also helps the optical system to fully process light. The arrangement of multiple light sources 221 helps to increase the lumen value by superimposing the light sources 221, thereby improving projection brightness, enhancing color performance, and improving the image quality of the projector.

[0041] The focusing assembly 3 includes a focusing camera 32 and a motor 31 for focusing. The extension direction of the focusing camera 32 is the same as the extension direction of the projection window 211. The motor 31 is located on the side of the main optical path module 21 away from the extended optical path module 22. The main control board 1 is located at the bottom of the projector body 2. The heat dissipation assembly 4 is located on the side of the main control board 1 away from the projector body 2, close to the extended optical path module 22, and is connected to the projector body 2 and / or the main control board 1 through a heat-conducting component 5.

[0042] The design of setting the focusing component 3 on the side of the main optical path module 21 away from the extended optical path module 22 can reduce the heat conduction of the heat source to the focusing component 3, reduce the risk of thermal distortion, improve focusing accuracy, and thus improve the projection imaging accuracy. In addition, the fact that the focusing component 3 is far away from the heat dissipation component 4 can also reduce the vibration impact generated by the heat dissipation fan 43, and avoid the problem of blurry projector imaging caused by shaking.

[0043] Understandably, the design of the heat dissipation component 4, located on the side of the main control board 1 away from the projector body 2 and close to the extended optical path module 22, helps to directionally deflect heat sources. The light source 221 is the main heat source in the overall projector structure. The heat dissipation component 4 is close to the extended optical path module 22 and directly connected to the light source 221 and / or the main control board 1 via the heat-conducting component 5, shortening the heat transfer path, reducing thermal resistance, and effectively improving heat dissipation efficiency. On the other hand, it achieves a zoned heat dissipation design. The heat from the extended optical path module 22 is handled by the heat dissipation component 4, while the main optical path module 21, being far from the heat source and the heat dissipation component 4, enjoys a more stable environment, improving imaging stability.

[0044] In addition, the layout of the main control board 1, projector body 2, focusing component 3, and heat dissipation component 4 can balance the weight of each component to a certain extent, making the projector more stable during projection.

[0045] For example, it may include heat pipes or vapor chambers made of metal materials such as copper or aluminum, or thermally conductive silicon or thermal paste.

[0046] Of course, the form of the heat-conducting component 5 described above is merely illustrative, intended to illustrate a possible implementation to aid in understanding the technical solution of this application. This application does not impose any limitations on the specific type of the heat-conducting component 5. In practical applications, the heat-conducting component 5 can be configured according to actual needs, and all such configurations should be covered within the scope of protection of this application.

[0047] In an optional embodiment, such as Figure 1 As shown, the heat dissipation assembly 4 includes: a housing 41 and a heat sink 42 and a heat dissipation fan 43 disposed in the housing 41;

[0048] The housing 41 has an air inlet 411 and an air outlet 412 that communicate with the internal space of the housing 41. The radiator 42 and the cooling fan 43 are located between the air inlet 411 and the air outlet 412. The radiator 42 is connected to the heat-conducting component 5. The cooling fan 43 is positioned towards the radiator 42 to form a cooling air duct from the air inlet 411 through the radiator 42 to the air outlet 412.

[0049] Understandably, a radiator 42 and a cooling fan 43 are arranged between the air inlet 411 and the air outlet 412 to form an effective heat dissipation airflow channel. Cool air is introduced through the air inlet 411, heat exchange is completed through the radiator 42, and finally, the air is exhausted through the air outlet 412. The radiator 42 is directly connected to the heat-conducting component 5, and the direct contact between the heat-conducting component 5 and the main control board 1 and / or the light source 221 enables faster and more efficient heat conduction, improving heat dissipation efficiency. The cooling fan 43 accelerates airflow, guiding the airflow to the radiator 42, optimizing the airflow path, further enhancing the heat dissipation effect, and improving overall cooling performance.

[0050] Furthermore, the heat sink 42 and cooling fan 43 are effectively integrated into the housing 41, which does not take up too much space and can dissipate heat efficiently. This compact and efficient design can meet the needs of small projectors.

[0051] In an optional embodiment, combined with Figure 1 and Figure 4 As shown, the radiator 42 includes a support frame 421 and at least two heat dissipation fins 422. The at least two heat dissipation fins 422 are equally spaced on the support frame 421, and heat dissipation gaps are formed between adjacent heat dissipation fins 422. The heat dissipation gaps are connected to the heat dissipation air duct.

[0052] The support frame 421 helps enhance the overall stability of the radiator 42 structure and prevents the cooling fan 43 from directly blowing on it, thus avoiding any impact. The equidistant design of the heat dissipation fins 422 effectively increases the surface area of ​​the radiator 42, providing more heat dissipation area and improving heat dissipation efficiency. The connection between the heat dissipation gaps and the heat dissipation airflow promotes airflow, making it easier for the heat inside the radiator 42 to be carried away by the airflow, enhancing the heat dissipation effect. The equidistant heat dissipation fins 422 also distribute heat evenly across the entire surface of the radiator 42, avoiding hotspot concentration and improving the uniformity of heat dissipation. The reasonable design of the heat dissipation gaps and airflow can also reduce noise generated during airflow, providing a quiet cooling effect.

[0053] Specifically, in some embodiments of this application, the extension direction of the heat dissipation gap formed between adjacent heat dissipation fins 422 is parallel to the gas flow direction of the heat dissipation duct. This design, on the one hand, helps to reduce the obstruction of the gas by the heat dissipation fins 422 when the gas flows in the heat dissipation duct, reduces friction, and allows the gas to pass through the radiator 42 more smoothly, thereby improving the heat dissipation speed. On the other hand, it allows the gas to fully contact the outer surface of the heat dissipation fins 422 when passing through the radiator 42, thereby improving the heat dissipation efficiency and optimizing the heat dissipation effect. Furthermore, it also helps to maintain the consistency of the gas flow direction when the air in the heat dissipation duct area flows through the radiator 42, thereby optimizing the heat dissipation performance.

[0054] In an optional embodiment, such as Figure 1 As shown, a shock-absorbing layer 431 is provided at the connection between the cooling fan 43 and the housing 41 and / or the heat-conducting component 5.

[0055] Understandably, the damping layer 431 can effectively absorb and buffer the vibration generated by the cooling fan 43, reduce the transmission of vibration, thereby maintaining the stability of the cooling fan 43 and the projector as a whole, helping to reduce noise generation and lower noise levels, and keeping the projection process of the projector stable.

[0056] The damping layer 431 can prevent vibration from affecting the radiator 42 or the heat conductor 5, so that the radiator 42 can continuously and efficiently conduct and dissipate heat. The stable operation of the cooling fan 43 can also more effectively promote airflow, thereby improving the efficiency of the entire heat dissipation system.

[0057] In an optional embodiment, such as Figure 1 As shown, the air inlet 411 and / or air outlet 412 are equipped with filters 413.

[0058] The filter 413 effectively filters dust, dirt, and other fine particles from the air, preventing them from entering the heat dissipation assembly 4 and accumulating on the radiator 42 or cooling fan 43. This helps maintain efficient heat dissipation performance and extends the projector's lifespan. Furthermore, the filter 413 helps keep the device clean, preventing dust accumulation from affecting its performance.

[0059] In an optional embodiment, combined with Figure 1 and Figure 3 As shown, the housing 41 and / or the main control board 1 also have a number of airflow hole arrays 414.

[0060] The airflow hole array 414, based on the original air inlet 411 and air outlet 412, helps to increase the heat dissipation surface area, thereby improving the heat dissipation efficiency. The airflow hole array 414 can effectively improve airflow, optimize airflow channels, and reduce airflow resistance. Air can circulate through these holes, allowing cold air to enter the device more evenly, while hot air can be quickly discharged, realizing heat exchange between the inside of the housing 41 and the outside, and between the inside of the housing 41 and the projector body 2, thereby improving the overall heat dissipation efficiency.

[0061] In addition, the reasonable layout of the airflow hole array 414 can reduce the noise generated by airflow during the heat dissipation process. By distributing multiple smaller airflow holes, the impact force of the airflow can be dispersed, thereby reducing wind noise and vibration.

[0062] In an alternative embodiment, the projection window 211 has a gradually expanding structure extending outward from the projector body 2, presenting a radial or clustered shape.

[0063] Understandably, the gradually expanding structure design of the projection window 211 can effectively guide light to diffuse in a wider direction, so that the projected image evenly covers the projection area, and helps to reduce the brightness difference between the center and the edge, providing a more balanced projection effect; the radial or clustered projection window 211 can reduce light spots and distortion in the projected image, making the projected content clearer; and by distributing the light in a radial or clustered manner, the projector can make more efficient use of its light source 221, expand the light diffusion angle, and improve the brightness and clarity of the projection.

[0064] In an optional embodiment, such as Figures 1 to 3 As shown, the focusing assembly 3 includes a motor 31 and a focusing camera 32. The motor 31 is electrically connected to the main control board 1. One end of the motor 31 is fixed to the projector body 2, and the other end is connected to the lens group of the focusing camera 32 (not shown in the figure). The motor 31 is used to drive the lens group to move along the axial direction of the focusing camera 32 to achieve focusing of the focusing camera 32.

[0065] Specifically, in some embodiments of this application, the automatic focusing of the projector includes controlling the focusing camera 32 to capture an image in front of the projector and transmitting the image to the main control board 1. The main control board 1 processes the image and obtains the image clarity. When the image clarity does not meet the preset clarity, it controls the motor 31 to drive according to the image clarity. After the motor 31 is driven, it controls the focusing camera 32 to capture an image again and obtains the image clarity. The focusing of the projector ends when the clarity of the image captured by the focusing camera 32 meets the preset clarity.

[0066] Understandably, the motor 31 is electrically connected to the main control board 1, enabling the focusing operation to be performed electronically and automatically. Through a stable mechanical connection, the focusing action is accurately transmitted to the lens group. The automated focusing system can significantly improve the focusing speed, reduce the time of manual intervention, and eliminate the need for manual focus adjustment, thereby providing faster image adjustment and avoiding focus deviation caused by external vibration or other factors, making the projected image more stable and clear.

[0067] In an optional embodiment, multiple light sources 221 are attached to the sidewall of the extended light path module 22. The main light path module 21 and the extended light path module 21 extend along a non-collinear direction and are interconnected to jointly enclose and form an approximately L-shaped bent projection light path.

[0068] Multiple light sources 221 provide stronger light intensity. The design of the main optical path module 21 and the extended optical path module 21 extending in a non-collinear direction and interconnected helps to evenly distribute light, improve light efficiency and brightness distribution, avoid brightness concentration or localized dark areas, increase the overall brightness of the projection area, and enhance the vibrancy and depth of image colors. This achieves a compact projector design while also improving image quality. The arrangement of multiple light sources 221 also increases their coverage area, adapting to large-screen or multi-surface projection needs. The light sources 221 emit light from different angles, enhancing the system's versatility. The distribution of the light sources 221 on the side walls also reduces light loss or spotting problems caused by concentrated light sources 221, ensuring uniform light propagation and improving image quality.

[0069] In addition, multiple light sources 221 are distributed on the side wall of the extended optical path module 22, which effectively avoids the overheating problem caused by the concentration of light sources 221 and improves the performance and lifespan of the equipment.

[0070] The embodiments of this application have at least the following beneficial effects:

[0071] This application provides a rugged mobile phone with an autofocus projector, which improves the position layout of the components, achieves a compact design, and enhances the projection performance of the mobile phone. Specifically, this application divides the projector body 2 into a main optical path module 21 and an extended optical path module 22. The modular design achieves a compact layout of the optical path, and the two are connected to form a projection optical path. The connected design can flexibly allocate internal space and avoid excessive compression of the optical path due to overall miniaturization (such as insufficient optical path length affecting image clarity), thereby ensuring the integrity and effectiveness of the projection optical path within a limited space.

[0072] The main control board 1 is located at the bottom of the projector body 2. The layered layout with the optical path module and heat dissipation component 4 reduces space conflicts and avoids functional interference caused by component crowding.

[0073] The extended optical path module 22 is equipped with a light source 221. The heat dissipation component 4 is located on the side of the main control board 1 away from the projector body 2, close to the extended optical path module 22, and is connected to the projector body 2 and / or the main control board 1 through the heat conduction component 5, which can efficiently dissipate heat and improve the heat dissipation effect. The focusing component 3 is located on the side of the main optical path module 21 away from the extended optical path module 22, which further optimizes the spatial distribution and achieves a compact design.
