[0033] The following detailed description will further describe the present application with reference to the above-mentioned drawings. DETAILED DESCRIPTION

[0034] With reference to the drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0035] It should be noted that when a component is referred to as being "fixed" to another component, it can be directly on the other component or there can be intervening components. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or there can be intervening components. The terms "vertical", "horizontal", "left", "right", and similar terms as used herein are for purposes of illustration and description only and are not intended to limit the scope of the application.

[0036] It should be noted that the terms "first", "second", and the like in the present application are only used to distinguish different devices, modules or units, and are not intended to limit the order or interdependence of the functions performed by these devices, modules or units.

[0037] The existing projector is usually used with a holder for the user to adjust different angles for viewing. However, the interface for connecting the projector and the external component is usually directly arranged on the projection module. When the projection module is connected with the external component, the external component will rotate with the projection module. When the projection module is rotated to a certain position, the external component can be in contact with other objects in the external environment, so that the projection module cannot continue to rotate. If the rotation is forced, the interface of the external component or the projection module can be damaged.

[0038] If the interface is transferred from the projection module to another position, the signal transmission between the external component and the projection module also needs to be considered. Specifically, on the one hand, the attenuation and impedance of the high-speed signal need to be controlled to ensure the integrity of the high-speed signal. On the other hand, the electromagnetic compatibility problem caused by the high-speed signal also needs to be considered.

[0039] Referring to FIG. 1, the projector 100 provided by the embodiment of the present application includes a projection module 10, a support module 30 and an interface module 50. The projection module 10 is used for projecting image light. The support module 30 is connected with the projection module 10 and is used for supporting the projection module 10. The interface module 50 includes an interface module 51, which is arranged on the support module 30 and is used for connecting with one or more external components.

[0040] Specifically, please refer to FIG. 2, in the embodiment, the projection module 10 is rotationally connected with the support module 30, that is, the projection module 10 can rotate relative to the support module 30. Wherein, the support module 30 includes a base 31, a connecting arm 33 and a rotating shaft 35. Wherein, one end of the connecting arm 33 is connected with the base 31, and the other end is connected with the rotating shaft 35, and the rotating shaft 35 is rotationally connected on the projection module 10, so that the projection module 10 can 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 through other structures. For example, the projection module 10 and the support module 30 are in rotational relationship through gears and the like, or the projection module 10 is further provided with a slide rail (not shown in the figure), so that the projection module 10 can translate relative to the base 31, or the connecting arm 33 is configured as an extension structure, so that the connecting arm 33 can drive the projection module 10 to translate relative to the base 31, and the like. By setting the connection structure between the projection module 10 and the support module 30, the support module 30 can play the effect of a gimbal for the projection module 10, so that external vibration will not affect the stability of the projection module 10, and the damping between the projection module 10 and the support module 30 can be adjusted, so that the projection module 10 can hover at any angle relative to the support module 30, thereby enabling the projection module 10 to hover and project images at any position, thereby improving the experience of the user. The specific connection mode between the projection module 10 and the support module 30 is not limited in the present application.

[0041] In the embodiment, the interface module 51 includes a plurality of interfaces 511, wherein the plurality of interfaces 511 can include one or more combinations of HDMI interface, USB interface, analog audio interface, digital audio interface, wired network interface. Wherein, part of the interfaces 511 are arranged on the connecting arm 33, and the other part of the interfaces 511 are arranged on the base 31. For example, the interfaces 511 for transmitting audio can be arranged on the connecting arm 33, and the interfaces 511 for transmitting HDMI signals or USB signals can be arranged on the base 31, which is not limited in the present application. In other embodiments, the plurality of interfaces 511 can also be arranged on the base 31 or on the connecting arm 33, which is not limited in the present application, as long as the interfaces 511 are arranged on the support module 30.

[0042] In other extended embodiments, part of the interfaces 511 can also be left on the projection module 10, which is determined according to actual use requirements, for example, a part of external components that do not affect the rotation of the projection module 10, or external components that have little effect on the rotation of the projection module 10 and are not easy to damage, and the interfaces 511 connected with the projection module 10 can also be directly arranged on the projection module 10, which is not limited in the present application.

[0043] Referring to FIG. 3, the interface module 50 further comprises a conversion module 53, which is arranged on the projection module 10. The conversion module 53 is connected with the interface module 51 for receiving the external signal transmitted by the external component and converting the external signal to the projection module 10. Specifically, the conversion module 53 is a communication module arranged inside the projection module 10, which is connected with the interface module 51 to communicate the projection module 10 with the external component for transmitting the external signal or sending the signal to the external component. The projection module 10 can comprise a processor 11, which is electrically connected with the conversion module 53 for adjusting the image light according to the signal received by the conversion module 53.

[0044] Referring to FIG. 2 and FIG. 3, in the embodiment, the interface module 50 further comprises a signal line 55, which is connected with the interface module 51 and the conversion module 53 at two ends. The signal line 55 extends from the position of the connecting arm 33 to the projection module 10 to connect the interface module 51 with the conversion module 53. Specifically, the signal line 55 is a multi-channel parallel high-speed low-attenuation signal line, which is used to transmit one or more of the HDMI TMDS high-speed signal, the USB2.0 signal, the USB3.0 signal, the SPI signal and the I2C signal. The bandwidth of the HDMI signal can reach 48Gbps at most, and the maximum bandwidth of the USB3.0 signal can reach 5Gbps. By using the multi-channel parallel high-speed low-attenuation signal line 55, the compatibility requirement can be met while ensuring the integrity of the high-speed signal, and the video signal can meet the eye diagram test, thereby ensuring the quality of the image projected by the projection module 10.

[0045] Referring to FIG. 4, in another embodiment, the interface module 50 further comprises a wireless transceiver module 57, the wireless transceiver module 57 comprising a first transceiver end 571 and a second transceiver end 573, the first transceiver end 571 being arranged on the support module 30 to be electrically connected with the interface module 51, and the second transceiver end 573 being arranged on the projection module 10 to be electrically connected with the adapter module 53. The first transceiver end 571 and the second transceiver end 573 transmit information through wireless communication. 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 a video signal transmitted by the interface module 51, and transmit the video signal to the second transceiver end 573. After receiving the video signal, the second transceiver end 573 can transmit the video signal to the projection module 10, so as to project a video corresponding to the video signal. Meanwhile, the projection module 10 can transmit an audio signal to the second transceiver end 573, and the second transceiver end 573 can transmit the audio signal to the first transceiver end 571, so as to transmit the audio signal to an external audio playing device through the interface module 51, and play the sound.

[0046] The wireless communication mode between the first transceiver end 571 and the second transceiver end 573 can be set according to actual needs. Different functions of the interface can correspond to different communication modes, such as infrared signal transmission, Bluetooth signal transmission, or different frequency band radio signal transmission, etc. The present application does not limit this.

[0047] In other embodiments, the interface module 50 can also simultaneously comprise the signal line 55 and the wireless transceiver module 57. For example, signals with high transmission speed and attenuation requirements can be transmitted through the signal line 55, so as to ensure the use experience of the projector 100. Signals with low transmission speed and attenuation requirements can be transmitted through the wireless transceiver module 57, so as to reduce the number of signal lines 55, thereby reducing the risk of damage to the signal line 55 and prolonging the service life of the hardware.

[0048] The projector 100 provided by the embodiments of the present application can fix the external components connected with the projector 100 relative to the support module 30, without moving with the movement of the projection module 10, which is conducive to ensuring the rotation range of the projection module 10 and reducing the risk of damage to the external components, thereby improving the use experience.

[0049] The embodiment of the present application further provides a projector 100, please refer to Figure 5, the projector 100 includes a base 31, a connecting arm 33 and a projection module 10. The base 31 includes a connecting portion 311 and a fixed portion 312. The fixed portion 312 is arranged on the connecting portion 311. The fixed portion 312 is provided with an interface module 51, and the interface module 51 is used for connecting external components. The connecting arm 33 is movably connected to the connecting portion 311, and the projection module 10 is movably arranged on the connecting portion 311 through the connecting arm 33. The projection module 10 can be electrically connected to the external components through the interface module 51. The projection module 10 can be a cuboid structure, and the projection module 10 is the main equipment of the projector 100, which can project images or videos onto a screen or a wall. The projection module 10 is movably connected to the connecting arm 33.

[0050] According to the projector 100 of the present application, the position of the fixed portion 312 of the base 31 is fixed, and the position of the projection module 10 relative to the connecting portion 311 can be adjusted through the connecting arm 33, and the position of the projection module 10 relative to the connecting portion 311 can be adjusted, so as to adjust the projection direction of the projection module 10. At the same time, the interface module 51 is arranged on the fixed portion 312 of the base 31, so that the position of the interface module 51 remains fixed, and the external components connected to the interface module 51 will not be moved with the connecting arm 33 and / or the projection module 10, so that the position of the external components can also remain fixed. Therefore, the adjustment flexibility of the projection direction of the projector 100 can be improved.

[0051] In some embodiments, a protective cover can be arranged on the surface of the base 31, and the interface module 51 can be arranged in the protective cover to improve the protection of the connection between the interface module 51 and the external components. Further, in a specific embodiment, the protective cover can be arranged on the fixed portion 312 of the base 31 to avoid affecting the connection between the connecting portion 311 and the connecting arm 33.

[0052] Please refer to Figures 5 and 6, the number of interface modules 51 is multiple. The types of interface modules 51 can also be multiple, and the interface modules 51 can be power interfaces, high-definition multimedia interfaces (HDMI), universal serial bus (USB) interfaces and the like. The USB interface can include one or more of Type-A interface, Type-B interface and Type-C interface. Accordingly, the external components can be wires corresponding to the types of interface modules 51, such as data lines, power lines and the like. The external components can also be storage devices, such as memory storage and the like.

[0053] Please refer to Figures 5 and 6, the base 31 has a side surface P1, a top surface P2 and a bottom surface P3. The top surface P2 connects the bottom surface P3 through the side surface P1.

[0054] In some embodiments, the top surface P2 comprises a connecting surface area P21 and an avoiding surface area P22. The connecting portion 311 comprises the connecting surface area P21. The fixing portion 312 comprises at least one of the avoiding surface area P22, the side surface P1 and the bottom surface P3. The projection module 10 is movably arranged on the connecting surface area P21 by the connecting arm 33. In this way, more area can be reserved for the interface module 51, which can ensure the strength of the base 31 and increase the number of the interface module 51, thereby improving the convenience of use of the projector 100.

[0055] Continuing to refer to FIGS. 5 and 6, the interface module 51 is arranged on the side surface P1 to facilitate connection with external components. The avoiding surface area P22 is arranged outside the connecting surface area P21 to reduce the possibility of interference of the connecting surface area P21 with the connection of the interface module 51 with external components at the avoiding surface area P22 when the avoiding surface area P22 is provided with the interface module 51.

[0056] In another embodiment, the connecting portion 311 comprises the top surface P2, and the projection module 10 is movably arranged on the top surface P2 by the connecting arm 33. The fixing portion 312 comprises at least one of the side surface P1 and the bottom surface P3. In this way, the connection stability of the connecting arm 33 and the connecting portion 311 can be improved.

[0057] Referring to FIG. 7, the base 31 is provided with a first cavity Q1, the connecting arm 33 is provided with a second cavity Q2, and the projection module 10 is provided with a third cavity Q3. The first cavity Q1, the second cavity Q2 and the third cavity Q3 are sequentially connected and form a wire channel M. The wire channel M is used to accommodate a signal line 55. The signal line 55 is used to electrically connect the interface module 51 and the projection module 10.

[0058] Specifically, the signal line 55 sequentially passes through the first cavity Q1, the second cavity Q2 and the third cavity Q3. One end of the signal line 55 is electrically connected to the interface module 51, and the other end of the signal line 55 is electrically connected to the projection module 10. In this way, when the connecting arm 33 moves relative to the base 31, the part of the signal line 55 located in the third cavity Q3 can be fixed relative to the projection module 10, and the parts of the signal line 55 located in the first cavity Q1 and the second cavity Q2 move slightly with the connecting arm 33 relative to the base 31. When the projection module 10 moves relative to the connecting arm 33, the part of the signal line 55 located in the first cavity Q1 can be fixed relative to the base 31, the part of the signal line 55 located in the second cavity Q2 is fixed relative to the connecting arm 33, and the part of the signal line 55 located in the third cavity Q3 moves with the projection module 10 relative to the base 31. In this way, the friction between the signal line 55 and the connecting arm 33 or the projection module 10 can be reduced, the loss of the signal line 55 can be reduced, and the connection reliability between the signal line 55 and the projection module 10 and the interface module 51 can be ensured.

The first circuit board 71 is connected to the electronic elements corresponding to the interface module 51. The second circuit board 15 is connected to the lens module, the optical module, and the like of the projection module 10. In this way, the external components can be electrically connected to the second circuit board 15 through the first circuit board 71 and the signal line 55, so as to realize the functions of power supply or signal transmission of the projection module 10. In addition, since the interface module 51 is arranged in the base 31, the electronic elements (for example, the first circuit board 71) corresponding to the interface module 51 can also be arranged in the base 31, so as to reduce the number of electronic elements in the projection module 10, and further reduce the volume of the projection module 10. In addition, when the volume of the projection module 10 is constant, since the first circuit board 71 and the like no longer occupy the space of the third chamber Q3, a higher-specification optical module, lens module, or heat dissipation module can be arranged, so as to improve the projection effect or heat dissipation effect of the projector 100, and further improve the design convenience of the projector 100.

[0061] In some embodiments, the projection module 10 comprises a housing 13, and the housing 13 defines the third chamber Q3.
