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 an intervening component. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only.

[0072] It should be noted that the terms "first", "second", and the like used in the present disclosure 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.

[0073] Reference is made to Figure 1The embodiment provides a projector 100, which comprises a support 10, a movable part 20 and a projector main body 30. The support 10 comprises a connecting part 11 and a fixed part 12. The fixed part 12 is arranged on the connecting part 11. The fixed part 12 is provided with a hardware interface 40, which is used for connecting an external device. The movable part 20 is movably connected to the connecting part 11, and the projector main body 30 is movably arranged on the connecting part 11 through the movable part 20. The projector main body 30 can be electrically connected to the external device through the hardware interface 40. The projector main body 30 can be a cuboid structure, and the projector main body 30 is a main device of the projector 100, which can project an image or a video onto a screen or a wall. The projector main body 30 is movably connected to the movable part 20.

[0074] According to the projector 100 of the present disclosure, the position of the fixed part 12 of the support 10 is fixed, and the position of the movable part 20 relative to the fixed part 12 and the position of the projector main body 30 relative to the connecting part 11 can be adjusted through the connecting part 11, so as to adjust the projection direction of the projector main body 30. Meanwhile, the hardware interface 40 is arranged on the fixed part 12 of the support 10, so that the position of the hardware interface 40 is fixed. The external device connected to the hardware interface 40 will not be moved with the movable part 20 and / or the projector main body 30, so that the position of the external device can also be fixed. Therefore, the adjustment flexibility of the projection direction of the projector 100 can be improved.

[0075] In some embodiments, a protective cover can be arranged on the surface of the support 10, and the hardware interface 40 can be arranged in the protective cover, so as to improve the protection of the connection between the hardware interface 40 and the external device. Further, in a specific embodiment, the protective cover can be arranged on the fixed part 12 of the support 10, so as to avoid affecting the connection between the connecting part 11 and the movable part 20.

[0076] Please refer to Figure 1 and Figure 2 The number of the hardware interfaces 40 is multiple. The types of the hardware interfaces 40 can also be multiple. The hardware interfaces 40 can be power interfaces, high definition multimedia interfaces (HDMI), universal serial bus (USB) interfaces and the like. The USB interface can comprise one or more of a Type-A interface, a Type-B interface and a Type-C interface. Accordingly, the external device can be a wire corresponding to the type of the hardware interface 40, such as a data line, a power line and the like. The external device can also be a storage device, such as a memory and the like.

[0077] Please refer to Figure 1 and Figure 2The support 10 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.

[0078] In some embodiments, the top surface P2 comprises a connecting surface area P21 and an avoiding surface area P22. The connecting portion 11 comprises the connecting surface area P21. The fixing portion 12 comprises at least one of the avoiding surface area P22, the side surface P1 and the bottom surface P3. The projector body 30 is movably arranged on the connecting surface area P21 through the movable member 20. In this way, more area can be reserved for the hardware interface 40, which can ensure the strength of the support 10 on the one hand, and can increase the number of hardware interfaces 40, thereby improving the use convenience of the projector 100.

[0079] Continuing to refer to Figure 1 and Figure 2 The hardware interface 40 is arranged on the side surface P1 to facilitate connection with external devices. The avoiding surface area P22 is arranged outside the connecting surface area P21, so as to reduce the possibility of the connecting surface area P21 interfering with the connection of the hardware interface 40 on the avoiding surface area P22 with external devices when the avoiding surface area P22 is provided with the hardware interface 40.

[0080] In another embodiment, the connecting portion 11 comprises the top surface P2, and the projector body 30 is movably arranged on the top surface P2 through the movable member 20. The fixing portion 12 comprises at least one of the side surface P1 and the bottom surface P3. In this way, the connection stability of the movable member 20 and the connecting portion 11 can be improved.

[0081] Referring to Figure 3 The support 10 is provided with a first cavity Q1, the movable member 20 is provided with a second cavity Q2, and the projector body 30 is provided with a third cavity Q3. The first cavity Q1, the second cavity Q2 and the third cavity Q3 are sequentially communicated and form a wire channel M. The wire channel M is used to accommodate internal wires 50. The internal wires 50 are used to electrically connect the hardware interface 40 and the projector body 30.

[0082] Specifically, the internal wire 50 passes through the first chamber Q1, the second chamber Q2 and the third chamber Q3 in sequence. One end of the internal wire 50 is electrically connected to the hardware interface 40, and the other end of the internal wire 50 is electrically connected to the projector main body 30. In this way, when the movable part 20 moves relative to the support part 10, the part of the internal wire 50 located in the third chamber Q3 can be fixed relative to the projector main body 30, and the parts of the internal wire 50 located in the first chamber Q1 and the second chamber Q2 move slightly with the movable part 20 relative to the support part 10. When the projector main body 30 moves relative to the movable part 20, the part of the internal wire 50 located in the first chamber Q1 can be fixed relative to the support part 10, the part of the internal wire 50 located in the second chamber Q2 is fixed relative to the movable part 20, and the part of the internal wire 50 located in the third chamber Q3 moves with the projector main body 30 relative to the support part 10. In this way, the friction between the internal wire 50 and the movable part 20 or the projector main body 30 can be reduced, the wear of the internal wire can be reduced, and the connection reliability between the internal wire 50, the projector main body 30 and the hardware interface 40 can be ensured.

[0083] In the present embodiment, an acoustic cavity component (not shown in the figure) of the projector main body 30 can also be arranged in the first chamber Q1, and the acoustic cavity component is used for playing audio of the projector main body 30.

[0084] In the present embodiment, referring to Figure 2 and Figure 3 , the projector 100 comprises a first circuit board 71 and a second circuit board 32. The first circuit board 71 is accommodated in the first chamber Q1. The second circuit board 32 is accommodated in the third chamber Q3. One end of the internal wire 50 is electrically connected to the first circuit board 71, and the other end of the internal wire 50 is electrically connected to the second circuit board 32. The first circuit board 71 is connected to the electronic components corresponding to the hardware interface 40. The second circuit board 32 is connected to the lens module, the optical module and the like of the projector main body 30. In this way, the external device can realize electrical connection with the second circuit board 32 through the first circuit board 71 and the internal wire 50, so as to realize the functions of power supply or signal transmission of the projector main body 30. In addition, since the hardware interface 40 is arranged on the support part 10, the electronic components (for example, the first circuit board 71) corresponding to the hardware interface 40 can also be arranged in the support part 10, so as to reduce the number of electronic components in the projector main body 30, and further reduce the volume of the projector main body 30. In addition, when the volume of the projector main body 30 is constant, since the first circuit board 71 and the like no longer occupy the space of the third chamber Q3, a higher-spec 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.

[0085] In some embodiments, the projector main body 30 comprises a shell 31, and the shell 31 defines the third chamber Q3.
