[0047] In related technologies, as shown in Figure 8, projectors typically use a rotating stand added to the main body of the projector to adjust the scene viewing angle, resulting in a large overall size of the projector, which is inconvenient to carry and store.

[0048] This application provides a projector to address the problems of existing projectors being bulky and lacking portability. The following description will be provided in conjunction with Figures 1-7.

[0049] The projector provided in this embodiment, as shown in Figures 1 and 2, includes a hinge 300, a first mounting box 100 and a second mounting box 200, an optical engine module 400, and a power supply module 500. The first mounting box 100 is rotatably connected to the second mounting box 200 via the hinge 300. The optical engine module 400 is mounted in the first mounting box 100, and the power supply module 500 is mounted in the second mounting box 200, and the power supply module 500 is electrically connected to the optical engine module 400.

[0050] It is understood that the power supply module 500 in this embodiment can be a battery module built into the projector; it can also be a power adapter installed in the projector, which can be connected to an external power source to power the optical engine module 400; it can also be a capacitor, solar power, or other form of power supply device, as long as it can power the optical engine module 400. For example, the projector is a miniature projector with a built-in battery module, which can be used without being plugged in. The first mounting box 100 is rotatably connected to the second mounting box 200 via a pivot 300, so that the first mounting box 100 can rotate relative to the second mounting box 200, thereby adjusting the projection angle of the optical engine module 400 in the first mounting box 100, realizing the projection angle adjustment of the projector, so that the projector can be placed flat and project along the horizontal direction, or the projector can be adjusted relative to the horizontal direction to project upward or downward as needed. For example, the projector can be adjusted within the range of -45° to 45° relative to the horizontal direction to match the angle requirements of the whole scene.

[0051] By installing the optical engine module 400 and the power supply module 500 in two independent first mounting boxes 100 and second mounting boxes 200 respectively, and connecting the first mounting boxes 100 and second mounting boxes 200 via a pivot 300, users can easily adjust the projection angle of the optical engine module 400 by simply rotating the first mounting box 100. This simple operation adapts to the needs of different usage scenarios, eliminates the need for the rotating bracket required in traditional designs, makes the overall structure of the projector more compact, reduces the space occupied by the projector, and makes the projector lighter and easier for users to carry.

[0052] Furthermore, the zoned arrangement of the optical engine module 400 and the power supply module 500 helps improve the projector's heat dissipation, avoids heat concentration, and enhances the projector's stability and lifespan. Since the power supply module 500 is typically heavier, installing it in the second mounting box 200, while the optical engine module 400 is installed in the first mounting box 100, effectively distributes the overall weight. When adjusting the projection angle, the weight of the power supply module 500 does not directly affect the rotation of the optical engine module 400. Therefore, rotating the first mounting box 100 with the second mounting box 200 as a reference is more stable. Moreover, when the projector is placed on a horizontal surface, the second mounting box 200 remains horizontal during the rotation of the first mounting box 100, reducing wobbling caused by uneven weight distribution and ensuring the stability of the projected image.

[0053] In an optional embodiment, referring to Figures 1 and 2, the second mounting box 200 has a side surface facing the first mounting box 100 and a supporting surface. The side surface and the supporting surface are different surfaces. For example, the side surface is the side of the second mounting box 200 away from the first mounting box 100, and the supporting surface is the side of the second mounting box 200 close to the first mounting box 100. The axis of the rotating shaft 300 is perpendicular to the supporting surface, so that the first mounting box 100 and the second mounting box 200 are arranged side by side to form a Rubik's Cube-like rotating structure. This reduces the volume occupied, maintains a compact structure, and facilitates the rotation of the first mounting box 100, thereby facilitating the adjustment of the projection angle of the optical engine module 400.

[0054] In an optional embodiment, referring to Figures 1 and 3, a cover plate bracket 110 is provided on the side of the first mounting box 100 near the second mounting box 200, and a turntable bracket 210 is provided on the side of the second mounting box 200 corresponding to the cover plate bracket 110. The cover plate bracket 110 is rotatably connected to the turntable bracket 210 via a rotating shaft 300.

[0055] Optionally, the cover plate bracket 110 can be a side plate or part of a side plate of the first mounting box 100, and the turntable bracket 210 can be a side plate or part of a side plate of the second mounting box 200. The design of the cover plate bracket 110 and the turntable bracket 210 increases the contact area during rotation, thereby improving the stability of the entire projector when adjusting the angle.

[0056] For example, the hinge 300 can be a damped hinge with a built-in damping mechanism, providing resistance during rotation and making the rotation process smoother. The damped hinge allows the optical engine module 400 to achieve precise hovering when adjusting the angle, enabling users to accurately position the optimal projection angle according to projection needs without additional fixing measures, simplifying the operation process. It also reduces the shaking of the optical engine module 400 caused by external vibrations or contact, maintaining the stability of the projected image.

[0057] In an alternative embodiment, referring to Figures 1, 4 and 5, a mounting cavity 111 is formed between the cover plate bracket 110 and the turntable bracket 210, and the rotating shaft 300 is disposed in the mounting cavity 111.

[0058] In this embodiment, the hinge 300 is at least partially embedded in the mounting cavity 111 and is not directly exposed to the outside, making the hinge 300 visually invisible. This eliminates the abruptness that may be caused by the traditional exposed hinge 300, making the appearance of the projector smoother and more beautiful, thereby improving the cleanliness and integration of the projector's appearance, and also making the projector structure more compact, which is conducive to reducing the overall size of the projector.

[0059] In an optional embodiment, as shown in Figures 3, 4, and 6, a limiting groove 112 is provided on the side of the cover plate bracket 110 facing the turntable bracket 210, and a limiting post 211 is provided on the turntable bracket 210. The limiting post 211 is slidably disposed in the limiting groove 112. In this embodiment, the limiting groove 112 can be a predetermined track or groove, and the shape of the limiting groove 112 can be arc-shaped. Its length determines the maximum rotation angle of the optical engine module 400. The turntable bracket 210 is provided with the limiting post 211. When the cover plate bracket 110 rotates relative to the turntable bracket 210, relative sliding occurs between the limiting post 211 and the limiting groove 112. When the limiting post 211 slides to the end of the limiting groove 112, it can prevent the cover plate bracket 110 from continuing to rotate, thereby limiting the rotation angle of the optical engine module 400, avoiding excessive rotation of the optical engine module 400, and ensuring the stable use of the projector.

[0060] In an optional embodiment, since the projection angle adjustment of the optical engine module 400 does not need to be adjusted within a 360-degree range, the angle adjustment range of the optical engine module 400 can be set to 90 degrees to meet the user's daily needs. In an optional embodiment, as shown in Figures 3, 4, and 6, a striker (not shown) is provided on the side of the cover plate bracket 110 facing the turntable bracket 210. The turntable bracket 210 is provided with multiple grooves 212 that match the striker at intervals along the circumferential direction. During the rotation of the cover plate bracket 110 relative to the turntable bracket 210, the striker is adapted to strike different grooves 212 in sequence. When the user rotates the first mounting box 100 (i.e., the optical engine module 400), the striker on the cover plate bracket 110 will strike the grooves 212 on the turntable bracket 210 in sequence, producing a series of "clicking" sounds. This sound feedback provides the user with an intuitive feel, allowing the user to perceive the angle and speed of rotation, thereby reducing the possibility of misoperation and improving the overall user experience. In an optional embodiment, as shown in Figures 1 and 3, the area of ​​the cover plate bracket 110 corresponding to the optical engine module 400 is provided with heat dissipation holes 113. The design of the heat dissipation holes 113 allows air circulation, thereby accelerating the dissipation of heat inside the optical engine module 400, preventing the device from overheating, effectively reducing the internal temperature of the optical engine module 400, reducing the impact of thermal stress on electronic components, and thus extending the service life of the projector.

[0061] In an optional embodiment, the turntable bracket 210 is provided with heat dissipation holes 113, which facilitates air circulation, improves heat dissipation, and also helps to dissipate heat from the power supply module 500 in the second mounting box 200.

[0062] For example, referring to FIG3, the shape of the heat dissipation hole 113 can be circular, rectangular, arc-shaped or other shapes, and the number of heat dissipation holes 113 can be multiple. This embodiment does not specifically limit this.

[0063] For example, the cover plate bracket 110 and the turntable bracket 210 can be formed by a one-piece mold of ultra-hard aluminum alloy, which has high strength, light weight and excellent wear resistance, improving stability and durability during rotation. In addition, the surfaces of the cover plate bracket 110 and the turntable bracket 210 can be provided with honeycomb-shaped heat dissipation and ventilation holes, which effectively improves heat dissipation and ventilation efficiency and meets the overall heat dissipation requirements of the projector.

[0064] In an optional embodiment, referring to Figures 1 and 5, a cable threading hole 310 is formed in the middle of the pivot 300. The power supply cable of the power supply module 500 passes through the cable threading hole 310 and connects to the optical engine module 400. By integrating the cable threading function into the pivot 300, the internal space requirement is reduced, making the overall design of the projector more compact. Furthermore, with the cable threaded inside the pivot 300, the possibility of cable tangling and interference during the rotation of the first mounting box 100 is reduced. When adjusting the projection angle, the cable will not be stretched or twisted, ensuring rotational flexibility and improving the stability of the projector.

[0065] In an alternative embodiment, referring to FIG1, the projector further includes an audio module 600, which is mounted in the second mounting box 200 and is located above the power supply module 500.

[0066] In this embodiment, the speaker module 600 is installed in the second mounting box 200, separately from the optical engine module 400, to avoid the speaker module 600 affecting the heat dissipation of the optical engine module 400. Furthermore, the speaker module 600 is installed above the power supply module 500. Since the power supply module 500 is typically heavy, this helps to lower the center of gravity of the projector and improve the stability of the optical engine module 400 during angle adjustment.

[0067] In an optional embodiment, referring to Figures 1 and 7, a mounting bracket 220 is provided inside the second mounting box 200. The mounting bracket 220 has a first mounting cavity 221 and a second mounting cavity 222 spaced apart along the height direction. The audio module 600 is mounted in the first mounting cavity 221, and the power supply module 500 is mounted in the second mounting cavity 222.

[0068] By setting the first mounting cavity 221 and the second mounting cavity 222 in the vertical direction, the internal space of the second mounting box 200 is effectively utilized, making the overall design more compact. Furthermore, the spacing between the first mounting cavity 221 and the second mounting cavity 222 helps to isolate the audio module 600 and the power supply module 500, reducing mutual interference, such as electromagnetic interference and heat transfer, and improving the stability of the projector's operation.

[0069] In an optional embodiment, the second mounting box 200 is provided with heat dissipation holes 113. The heat dissipation holes 113 can be located at the bottom, top or side of the second mounting box 200, and can be set according to specific heat dissipation requirements to help dissipate the heat generated by the power supply module 500 and the audio system during operation.

[0070] In an alternative embodiment, referring to FIG1, the projector further includes a heat dissipation module 700, which is mounted in the first mounting box 100 and is located below the optical engine module 400.

[0071] For example, the heat dissipation module 700 may include a turbine fan placed below the optical engine module 400, which directly cools the optical engine module 400 by using the airflow generated by the fan, thereby improving heat dissipation efficiency.

[0072] In some optional implementations, referring to Figure 1, the projector also includes a main control module 800 and a perception algorithm module 900. The optical engine module 400, heat dissipation module 700, main control module 800, and perception algorithm module 900 within the first mounting box 100 on the left are integrated into a single unit. The rotating shaft 300 is concealed within the cover bracket 110. The power supply module 500 and audio module 600 within the second mounting box 200 on the right are mounted as a single unit, and then connected to the rotating shaft 300 via the turntable bracket 210, enabling rotational connection between the first mounting box 100 and the second mounting box 200. The cover bracket 110, rotating shaft 300, and turntable bracket 210 work together to achieve damped hovering at any angle within a 90-degree range, providing a user experience that adjusts the projection angle for both upward and downward projection and matches the angle requirements of various projection scenarios.

[0073] The projector provided in this embodiment adopts a Rubik's Cube-like design, including a hinge 300, a first mounting box 100 and a second mounting box 200, an optical engine module 400, and a power supply module 500. The first mounting box 100 is rotatably connected to the second mounting box 200 via the hinge 300. The optical engine module 400 is mounted in the first mounting box 100, and the power supply module 500 is mounted in the second mounting box 200, and the power supply module 500 is electrically connected to the optical engine module 400. By installing the optical engine module 400 and the power supply module 500 in different first mounting boxes 100 and second mounting boxes 200 respectively, and rotatably connecting the first mounting box 100 and the second mounting box 200 via the hinge 300, the projection angle of the optical engine module 400 can be adjusted by rotating the first mounting box 100, without the need for an additional rotating bracket. This makes the projector structure more compact, reduces the space occupied by the projector, and improves the portability of the projector.

[0074] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
