[0002] This application claims priority to Chinese Patent No. 202422383273.0, filed on September 27, 2024, entitled “Projector”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of display technology, and more particularly to a projector. Background Technology

[0004] To facilitate viewing angle adjustments, some projectors are equipped with gimbal stands, allowing the projection module mounted on the stand to be freely adjusted. However, the projection module also has interfaces for connecting external devices or cables, such as HDMI cables or USB flash drives. When these external components are connected to the projection module, they move with the rotation of the projection module, restricting its range of motion and potentially damaging these external components, thus affecting the user experience. Utility Model Content

[0005] This application discloses a projector that can prevent external components connected to the projector from affecting the projector's angle adjustment.

[0006] This application relates to a projector, comprising:

[0007] Projection module, used to project image light;

[0008] A support module, wherein the projection module is connected to the support module, and the support module is used to support the projection module; and

[0009] An interface module includes an interface module and a converter module. The interface module is disposed on the support module and is used to connect to one or more external components. The converter module is disposed on the projection module and is communicatively connected to the interface module. It is used to receive external signals received from the interface module and to transfer the external signals to the projection module.

[0010] The support module includes a base and a connecting arm. One end of the connecting arm is connected to the base, and the projection module is connected to the other end of the connecting arm. The interface module is at least partially disposed on the base.

[0011] The projector provided in this application sets the interface module of the interface module on the support module and the adapter module on the projection module, and sets the interface module and the adapter module to communicate with each other. This allows the external components connected to the support module to not move with the projection module when the projection module is adjusted relative to the support module. This avoids limiting the rotation range of the projection module and also avoids damage to the external components due to the movement of the projection module, which is beneficial to improving the user experience.

[0012] In one embodiment, the interface module further includes a signal line, the two ends of which are connected to the interface module and the adapter module, respectively.

[0013] In one embodiment, the signal line extends from the location of the connecting arm into the projection module.

[0014] In one embodiment, the support module further includes a pivot, and the projection module and the connecting arm are rotatably connected via the pivot. The signal line is partially embedded inside the connecting arm and extends from the connecting arm into the projection module via the pivot.

[0015] In one embodiment, the signal line extends from the connecting arm to the base for electrical connection with the interface module.

[0016] In one embodiment, the interface module is at least partially disposed on the connecting arm, and the signal line is embedded inside the connecting arm to be electrically connected to the interface module.

[0017] In one embodiment, the signal line is used to transmit one or more of the following: HDMI TMDS high-speed signal, USB 2.0 signal, USB 3.0 signal, SPI signal, and I2C signal.

[0018] In one embodiment, the interface module further includes a wireless transceiver module, which includes a first transceiver end and a second transceiver end.

[0042] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this article are for illustrative purposes only.

[0045] It should be noted that the concepts of "first" and "second" mentioned in this application are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0046] Existing projectors are usually used with a pan-tilt unit to facilitate viewing at different angles. However, since the interface between the projector and external components is usually located directly on the projection module, the external components will rotate with the projection module when the projection module is connected. When the projection module rotates to certain positions, the external components may come into contact with other objects in the external environment, causing the projection module to stop rotating. If it is forced to rotate, it may damage the interface of the external components or the projection module.

[0047] If the interface is moved from the projection module to another location, the signal transmission between the external components and the projection module also needs to be considered. Specifically, firstly, it is necessary to control the attenuation and impedance of high-speed signals to ensure their integrity. Secondly, electromagnetic compatibility issues arising from high-speed signals also need to be considered.

[0048] Please see Figure 1 The projector 100 provided in this embodiment includes a projection module 10, a support module 30, and an interface module 50. The projection module 10 projects image light. The support module 30 is connected to the projection module 10 and supports the projection module 10. The interface module 50 includes an interface module 51, which is disposed on the support module 30 and is used to connect to one or more external components.

[0049] Specifically, please refer to Figure 2In this embodiment, the projection module 10 is rotatably connected to the support module 30, meaning the projection module 10 can rotate relative to the support module 30. The support module 30 includes a base 31, a connecting arm 33, and a rotating shaft 35. One end of the connecting arm 33 is connected to the base 31, and the other end is connected to the rotating shaft 35. The rotating shaft 35 is rotatably connected to the projection module 10, allowing the projection module 10 to rotate around the rotating shaft 35, thereby rotating relative to the base 31. In other embodiments, the projection module 10 and the support module 30 can also be connected by other structures. For example, the projection module 10 and the support module 30 can be rotated via gears or other structures, or the projection module 10 can be further provided with a slide rail (not shown in the figure) to allow the projection module 10 to translate relative to the base 31. Alternatively, the connecting arm 33 can be configured as a telescopic structure, allowing the projection module 10 to translate relative to the base 31 through extension and retraction, etc. By setting the connection structure between the projection module 10 and the support module 30, the support module 30 can act as a gimbal for the projection module 10, preventing external vibrations from affecting the stability of the projection module 10. Furthermore, the damping between the projection module 10 and the support module 30 can be adjusted, allowing the projection module 10 to hover at any angle relative to the support module 30. This enables the projection module 10 to hover and project images at any position, thereby improving the user experience. This application does not limit the specific connection method between the projection module 10 and the support module 30.

[0050] In this embodiment, the interface module 51 includes multiple interfaces 511, which may include one or more combinations of HDMI interfaces, USB interfaces, analog audio interfaces, digital audio interfaces, and wired network ports. Some interfaces 511 are disposed on the connecting arm 33, while others are disposed on the base 31. For example, the interfaces 511 used for transmitting audio may be disposed on the connecting arm 33, while the interfaces 511 used for transmitting HDMI or USB signals may be disposed on the base 31; this application does not impose any limitations on this. In other embodiments, all interfaces 511 may be disposed on the base 31 or all on the connecting arm 33; this application does not impose any limitations on this, as long as the interfaces 511 are disposed on the support module 30, they are all within the scope of this application.

[0051] In other extended embodiments, some interfaces may also be provided on the projection module 10, depending on the actual usage requirements. For example, some external components that do not affect the rotation of the projection module 10, or external components that have little impact on the rotation of the projection module 10 and are not easily damaged, may have their interfaces connected to the projection module 10 directly on the projection module 10. This application does not limit this.

[0052] Please see Figure 3The interface module 50 also includes a converter module 53, which is disposed on the projection module 10. The converter module 53 is used to communicate with the interface module 51 to receive external signals transmitted by external components received by the interface module 51 and to transfer the external signals to the projection module 10. Specifically, the converter module 53 is a communication module disposed inside the projection module 10, used to connect with the interface module 51, thereby connecting the projection module 10 to external components for transmitting or sending signals to external components. The projection module 10 may include a processor 11, which is electrically connected to the converter module 53 and is used to adjust the image light according to the signals received by the converter module 53.

[0053] Please refer to the following: Figure 2 and Figure 3 In this embodiment, the interface module 50 further includes a signal line 55, with both ends of the signal line 55 connected to the interface module 51 and the adapter module 53, respectively. The signal line 55 extends from the connecting arm 33 into the projection module 10, thereby connecting the interface module 51 and the adapter module 53. Specifically, the signal line 55 is a multi-parallel high-speed, low-attenuation signal line used to transmit one or more of the following: HDMI TMDS high-speed signals, USB 2.0 signals, USB 3.0 signals, SPI signals, and I2C signals. The maximum bandwidth of the HDMI signal can reach 48Gbps, and the maximum bandwidth of the USB 3.0 signal can reach 5Gbps. By using a multi-parallel high-speed, low-attenuation signal line 55, the integrity of the high-speed signal can be guaranteed while meeting compatibility requirements, and the video signal can meet eye diagram testing, thereby ensuring the quality of the image projected by the projection module 10.

[0054] Please see Figure 4In another embodiment, the interface module 50 further includes a wireless transceiver module 57, which includes a first transceiver end 571 and a second transceiver end 573. The first transceiver end 571 is disposed on the support module 30 for electrical connection with the interface module 51, and the second transceiver end 573 is disposed on the projection module 10 for electrical connection with the adapter module 53. The first transceiver end 571 and the second transceiver end 573 transmit information wirelessly. Specifically, the first transceiver end 571 can send signals to the second transceiver end 573 and can also receive signals sent by the second transceiver end 573. The second transceiver end 573 can send signals to the first transceiver end 571 and can also receive signals sent by the first transceiver end 571. For example, the first transceiver end 571 can receive video signals transmitted by the interface module 51 and transmit the video signals to the second transceiver end 573. After receiving the video signals, the second transceiver end 573 can transmit them to the projection module 10, thereby projecting the video corresponding to the video signals. The projection module 10 can also transmit audio signals to the second transceiver 573, which transmits the audio signals to the first transceiver 571, thereby transmitting the audio signals to an external audio playback device through the interface module 51 to play sound.

[0055] The wireless communication method between the first transceiver 571 and the second transceiver 573 can be set according to actual needs. Different functional interfaces can correspond to different communication methods, such as infrared signal transmission, Bluetooth signal transmission, or radio signal transmission in different frequency bands. This application does not impose any restrictions on this.

[0056] In other embodiments, the interface module 50 may also include both a signal line 55 and a wireless transceiver module 57. For example, signals with high requirements for transmission speed and attenuation can be transmitted through the signal line 55 to ensure the user experience of the projector 100. Signals with lower requirements for transmission speed and attenuation can be transmitted through the wireless transceiver module 57, thereby reducing the number of lines on the signal line 55, reducing the risk of damage to the signal line 55, and extending the lifespan of the hardware.

[0057] The projector 100 provided in this application embodiment, by setting the interface module 51 on the support module 30, allows the external components connected to the projector 100 to be fixed relative to the support module 30, without needing to move with the movement of the projection module 10. This helps to ensure the rotation range of the projection module 10, reduce the wind direction that could damage the external components, and thus improve the user experience.

[0058] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
