Technical Field

[0001] This utility model relates to the field of projector structure technology, and more specifically, to a split-type projector. Background Technology

[0002] Currently, projection technology is widely used in e-sports entertainment, education, and home entertainment. In modern electronic device design, especially portable multimedia devices like projectors, heat dissipation performance has become a key factor affecting their performance, reliability, and lifespan. Projectors contain various heat-generating components, such as the light source module, processor, and wireless communication module, which generate a significant amount of heat during operation. Effectively managing this heat is crucial for maintaining normal device operation, extending its lifespan, and preventing overheating-related malfunctions. Currently, most projectors on the market have the motherboard and lens module assembled together in the same cavity. Due to the close proximity between them, the heat dissipation of the lens module can significantly impact the motherboard's performance and lifespan, reducing product performance. Furthermore, assembling the motherboard and lens module in the same cavity requires users to use an additional device to rotate the projector to avoid obstructing their view, thus degrading the user experience.

[0003] In conclusion, heat dissipation between the projector lens and the motherboard is one of the most important technical problems that urgently need to be solved in the development of modern electronic devices. Utility Model Content

[0037] Currently, projection technology is widely used in e-sports entertainment, education, and home entertainment. In the design of modern electronic devices, especially portable multimedia devices like projectors, heat dissipation performance has become one of the key factors affecting their performance, reliability, and lifespan. Projectors contain various heat-generating components, such as the light source module, processor, and wireless communication module, which generate a significant amount of heat during operation. Effectively managing this heat is crucial for maintaining normal device operation, extending its lifespan, and preventing overheating-related malfunctions. The optical system of a projector typically includes a lens and a motherboard, which are structurally closely connected but each performs different functions. The lens is responsible for capturing images and magnifying and projecting them onto the screen, while the motherboard integrates processing, display driving, audio processing, and other functions, serving as the core control unit of the entire projector. Because projectors typically operate in a relatively enclosed space, coupled with high-density electronic components and a powerful light source, heat dissipation becomes a major design challenge.

[0038] Projector design often requires striking a balance between compact size and efficient heat dissipation. The lens, as the central component of the optical system, determines the light path, while the motherboard is the control hub of the entire device. Within a limited space, the layout of the lens and motherboard needs careful consideration to avoid heat sources affecting optical performance. Currently, most projectors on the market assemble the motherboard and lens module together in the same cavity. Due to the close proximity between them, the heat dissipation of the lens module significantly impacts the motherboard's operation and lifespan, reducing product performance. Furthermore, assembling the motherboard and lens module in the same cavity requires users to use an additional device to rotate the projector to avoid obstructing their view, thus degrading the user experience.

[0039] Traditional solutions might involve using heat pipes, heat sinks, or heat collectors to help conduct heat to the outside, but these designs often require additional space, increasing the size of the device. Inside a projector, heat typically concentrates on high-power components such as the light source, processor, and wireless module. Without effective thermal management, this heat can accumulate rapidly, leading to localized overheating and affecting the device's stability and performance.

[0040] In summary, heat dissipation between the projector lens and the motherboard is one of the most important technical problems that urgently need to be solved in the development of modern electronic devices.

[0041] Please refer to Figures 1-3 This embodiment provides a split-type projector 100, which can effectively improve the technical problems mentioned above, reduce the impact of heat dissipation of lens 12 on the working state and lifespan of motherboard 32, and improve the projector's lifespan and user experience.

[0042] The split-type projector 100 includes an optical module 10, a connection module 20, and a control module 30. The connection module 20 is connected to the optical module 10, and the control module 30 is connected to the connection module 20. The control module 30 and the optical module 10 are set separately.

[0043] In this embodiment, the optical module 10 and the control module 30 are connected separately through the connecting module 20, which increases the distance between the optical module 10 and the control module 30, so that the heat generated by the optical module 10 during operation will not affect the normal operation of the control module 30 as much as possible.

[0044] Understandably, the optical module 10 includes a housing 11, a lens 12, and a first heat sink 13. Both the lens 12 and the first heat sink 13 are mounted within the housing 11, with the lens 12 embedded within it. The housing 11 is connected to the connecting module 20. The lens 12 captures images and magnifies them for projection onto a screen. The first heat sink 13 is positioned around the lens 12 to dissipate heat generated during operation, preventing overheating and ensuring normal operation. The housing 11 has first heat dissipation holes corresponding to the position of the first heat sink 13.

[0045] In this embodiment, the first heat sink 13 can be a fan. In other embodiments, the first heat sink 13 can also be heat dissipation fins, which are not specifically limited here.

[0046] To allow light from lens 12 to propagate and form a projected image, a projection hole 101 is provided on the housing 11. The position of the projection hole 101 corresponds to the position of lens 12, allowing light emitted from lens 12 to be projected through the projection hole 101 to form a projected image. In this embodiment, the projection hole 101 has a circular structure and is covered by a cover plate 40 to prevent dust from entering the housing 11 and affecting the clarity of the projected image.

[0047] In this embodiment, the cover 11 includes a housing 111 and a cover 112. The housing 111 has an opening, and the cover 112 is detachably covered by the opening of the housing 111, thereby forming a closed chamber structure together with the housing 111. The lens 12 and the first heat sink 13 are both installed inside the housing 111. The projection hole 101 is provided on the cover 112, and the first heat dissipation hole is provided on the housing 111.

[0048] It should be further explained that the cover 111 includes a first cover 1111 and a second cover 1112. The first cover 1111 and the second cover 1112 are detachably connected. The cover 112 includes a round cover 1121 and a U-shaped rod 1122. The two ends of the U-shaped rod 1122 are respectively connected to the edge of the round cover 1121. The midpoint of the U-shaped rod 1122 is flush with the center of the round cover 1121. The projection hole 101 is provided on the round cover 1121.

[0049] During assembly, the first cover 1111 and the second cover 1112 are placed on both sides of the U-shaped rod 1122 respectively. The first cover 1111 and the second cover 1112 are aligned and spliced ​​on the inside of the U-shaped rod 1122. The U-shaped rod 1122 covers the connection position of the first cover 1111 and the second cover 1112, thereby fixing the first cover 1111 and the second cover 1112. The round cover 1121 covers the opening position formed after the first cover 1111 and the second cover 1112 are spliced.

[0050] In this embodiment, the shield 11 is a projectile structure. In other embodiments, the shield 11 may also be a cylindrical or square structure. No specific limitation is made here.

[0051] Furthermore, in order to ensure that the light emitted by the lens 12 can be concentrated to the maximum extent at the position of the projection hole 101, the optical module 10 in this embodiment also includes a light propagation cavity 14. The light propagation cavity 14 is disposed inside the cover 11, and the entrance position of the light propagation cavity 14 corresponds to the position of the lens 12. The light propagation cavity 14 is used to propagate the light emitted by the lens 12.

[0052] Specifically, the light propagation cavity 14 is a long, narrow cavity, and the light propagation cavity 14 includes multiple propagation panels. The multiple propagation panels are arranged at an angle to each other, so that the light emitted by the lens 12 can be reflected sequentially on the multiple propagation panels, thereby concentrating the light at the position of the projection hole 101 and shooting it out.

[0053] In this embodiment, the light propagation cavity 14 is an L-shaped chamber, and the inlet and outlet of the light propagation cavity 14 are arranged in opposite directions.

[0054] It should be noted that the connection module 20 includes a connection shell, an optical module 10, and a control module 30, respectively disposed at opposite ends of the connection shell. The connection shell has a hollow structure with openings at both ends. The optical module 10 and the control module 30 communicate via data cables inside the connection shell. The data cable of the optical module 10 can pass through the inside of the connection shell to reach the control module 30, and vice versa. This communication connection between the optical module 10 and the control module 30 results in a cleaner and more aesthetically pleasing overall appearance of the projector, improving user comfort.

[0055] In this embodiment, the connecting shell is arranged vertically, with the optical module 10 located at the top and the control module 30 located at the bottom. Understandably, the optical module 10 and the control module 30 form a split structure via the connecting shell, with the control module 30 serving as a base to support both the connecting shell and the optical module 10. Furthermore, positioning the optical module 10 above the control module 30 minimizes projector obstruction of the user's view, enhancing the user experience.

[0056] Specifically, the optical module 10, the connecting shell, and the control module 30 can form an I-shaped structure or a Z-shaped structure, without any specific limitations.

[0057] In other embodiments, the connecting shell may also be arranged in a horizontal direction, with the optical module 10 and the control module 30 respectively arranged at both ends of the connecting shell in a horizontal direction.

[0058] To further improve the adjustment of the projection height and enhance the user experience, the split-type projector 100 provided in this embodiment also includes a rotating part. The rotating part is disposed in the connecting shell and is used to drive the connecting shell to rotate up and down in the vertical direction, thereby driving the optical module 10 or the control module 30 to rotate up and down in the vertical direction, thereby adjusting the projection height. This allows users to adjust the projection height according to their own usage habits, thereby changing the projection direction and further enhancing the user experience.

[0059] In this embodiment, the connecting shell includes a first shell 21 and a second shell 22. The first shell 21 and the second shell 22 are respectively connected to the optical module 10 and the control module 30. The first shell 21 and the second shell 22 together form a strip-shaped channel. The first shell 21 and the second shell 22 are rotatably connected by a rotating part. Specifically, the first shell 21 is connected to the cover 11 of the optical module 10, and the second shell 22 is connected to the control module 30.

[0060] In this embodiment, the rotating part can be a rotating shaft.

[0061] Specifically, the pivot is installed inside the hollow of the connecting shell. The shapes of the first shell 21 and the second shell 22 are adapted to each other, and the first shell 21 and the second shell 22 are spliced ​​together to form a whole, and then connected by the pivot. When it is necessary to adjust the projection height, the first shell 21 is manually moved so that the first shell 21 can rotate along the central axis of the pivot, so that the first shell 21 drives the cover 11 to tilt up or down, raising or lowering the projection height of the lens 12, thereby realizing the adjustment of the projection height of the optical module 10.

[0062] Specifically, the vertical rotation angle of the optical module 10 and / or the control module 30 is 0°-5°. In this embodiment, the vertical rotation angle of the optical module 10 and / or the control module 30 is 5°. In other embodiments, the vertical rotation angle of the optical module 10 and / or the control module 30 can also be 0°, 2°, 3° or 4°, and is not specifically limited here.

[0063] In this embodiment, both the connecting shell and the cover 11 are made of plastic. In other embodiments, the connecting shell and the cover 11 may also be made of metal or other materials, and no specific limitation is made here.

[0064] It should also be noted that the control module 30 includes a housing 31, a motherboard 32, and a second heat sink. Both the motherboard 32 and the second heat sink are installed inside the housing 31, which is connected to the connection module 20. The housing 31 has a cuboid structure, allowing it to stably support both the connection housing and the optical module 10, ensuring projection stability, even with the optical module 10 and control module 30 being in a split configuration.

[0065] In this embodiment, the second heat sink can be a fan. In other embodiments, the second heat sink can also be heat dissipation fins, which are not specifically limited here.

[0066] Specifically, the outer casing 31 has a through hole and a second heat dissipation hole for heat dissipation. The through hole is used to accommodate an external power supply for connection or to accommodate a data cable for data exchange. The position of the second heat dissipation hole corresponds to the position of the second heat sink. The end of the outer casing 31 that is aligned with the projection direction is defined as the front end, and the end of the outer casing 31 that is opposite to the projection direction is defined as the rear end. The through hole and the second heat dissipation hole are located at the rear end of the outer casing 31.

[0067] Specifically, the outer shell 31 is connected to the second shell 22 of the connecting shell.

[0068] In this embodiment, the outer shell 31 is made of plastic. In other embodiments, the outer shell 31 may also be made of metal or other materials, and no specific limitation is made here.

[0069] Furthermore, the rear of the casing 31 is equipped with buttons, which are connected to the motherboard 32. The buttons can be used to control the projector to turn on and off, making it convenient for users to control and manage the projector; the buttons can also be used to control the projection volume, etc., without specific limitations.

[0070] Understandably, the control module 30 also includes a speaker, which is connected to the motherboard 32. The speaker's data cable communicates with the motherboard 32, enabling the speaker to convert electrical signals into sound signals, thereby emitting sound.

[0071] Furthermore, the front end of the housing 31 is provided with several sound outlets for transmitting audio emitted by the speaker. Among them, some of the sound outlets are configured as dense holes to play the audio emitted by the speaker.

[0072] In addition, projectors are generally used with a remote control. To facilitate the storage of the remote control, the split-type projector 100 in this embodiment also includes a shelf, which is movably installed inside the outer casing 31. The shelf has a receiving cavity for storing miscellaneous items. The receiving cavity of the shelf can be used to place items such as the remote control and mobile phones, making it easier for users to find the remote control immediately when they need to use the projector, thus making it more convenient to use.

[0073] The "accommodation cavity" refers to the hollow cavity formed by the shelf that is sealed and isolated from the outside.

[0074] In this embodiment, the shelf is slidably disposed inside the outer casing 31. When the shelf is full of items, it can slide into the outer casing 31 without affecting the use of the projector and reducing the size of the projector.

[0075] Of course, the storage compartments of the shelf can also be used to store items such as tissues or headphones, without any specific limitations.

[0076] In other embodiments, the shelf may also be disposed on the side of the housing 31 away from the sound outlet, and the shelf may be connected to the outer surface of the housing 31. In other embodiments, the shelf may also be disposed outside the optical module 10, without specific limitation.

[0077] To prevent items stored in the shelves from falling out, a sliding baffle can be installed on the shelves to cover the items inside, making them easier to use.

[0078] The split-type projector 100 provided in this embodiment has at least the following advantages:

[0079] In this embodiment, the optical module 10 and the control module 30 of the split projector 100 are connected separately through the connecting module 20, which increases the distance between the optical module 10 and the control module 30, so that the heat generated by the optical module 10 during operation will not affect the normal operation of the control module 30 as much as possible.

[0080] In summary, this utility model embodiment provides a split-type projector 100, which includes an optical module 10, a connection module 20, and a control module 30. The connection module 20 is connected to the optical module 10, and the control module 30 is connected to the connection module 20, with the control module 30 and optical module 10 being separate components. In use, the optical module 10 and control module 30 are connected via the connection module 20. This separate design reduces the impact of heat generated by the optical module 10 during operation on the operating state and lifespan of the motherboard 32 within the control module 30, thus improving the projector's lifespan and user experience.
