The first bracket sub-housing 201 and the second bracket sub-housing 202 are integrally detachably fixedly connected, wherein the first bracket arm sub-housing 221 and the second bracket arm sub-housing 222 are correspondingly connected, and the first base sub-housing 211 and the second base sub-housing 212 are correspondingly connected, such as by snap-fit ​​fasteners. Among them, the first bracket arm sub-shell 221 is arranged on the inner side of the second bracket arm sub-shell 222, that is, the first bracket arm sub-shell 221 is closer to the fuselage shell 10 than the second bracket arm sub-shell 222, and the fuselage shell 10 is connected to the first bracket arm shell 221 through the rotating member 23; the first base sub-shell 211 is arranged on the top side of the second base sub-shell 212, that is, the first base sub-shell 211 is closer to the fuselage shell 10 than the second base sub-shell 212. Therefore, in this embodiment, the base shell 21 and the bracket arm shell 22 are partially connected as one body, which can be understood as follows: the bracket assembly 20 includes a detachably mounted first bracket sub-shell 201 and a second bracket sub-shell 202, the first bracket sub-shell 201 is located above the second bracket sub-shell 202, and after the two are installed, a part of them together form the base shell 21, and the other part together form the bracket arm shell 22. The second bracket sub-shell 202 is fixed to the first bracket sub-shell 201 by buckling and locking screws, and covers the bottom and left and right sides of the first bracket sub-shell 201 from the outside. After the body shell 10 is installed on the first bracket sub-shell 201 , the first bracket sub-shell 201 and the second bracket sub-shell 202 are installed to realize the assembly of the whole machine.

[0030] In one embodiment, the first base subshell 211 has a front end surface 2111, and a sound outlet is opened on the front end surface 2111. The sound area of ​​the speaker 40 faces the sound outlet. The outer surface of the front end surface 2111 can be covered with a sound-permeable decorative panel 50, which is designed to be wrapped in cloth, for example. A metal bottom plate 213 is fixedly connected inside the second base sub-shell 212, and the metal bottom plate 213 is locked and fixed to the second base sub-shell 212 along the height direction of the projection device by fasteners; the metal bottom plate 213 extends toward the front end face of the first base sub-shell 211 and partially tilts its edge to form a mounting portion 2131 parallel to the front end face 2111 of the first base sub-shell 211, and the front end face 2111 of the first base sub-shell 211 and the mounting portion 2131 are fixedly connected by fasteners along the approximately horizontal direction of the projection device, so that the first base sub-shell 211 is fixed to the metal bottom plate 213, so that the metal bottom plate 213 is firmly fixed to the first base sub-shell 211 and the second base sub-shell 212 at the same time, and is approximately perpendicular to the mounting direction of the first bracket sub-shell 201 and the second bracket sub-shell 202, which can further improve the assembly strength, prevent the first bracket sub-shell 201 and the second bracket sub-shell 202 from being separated when the projection device falls, and improve the anti-fall performance. Among them, the metal bottom plate 213 is preferably made of alloy material.

[0031] The speaker 40 is installed on the first base sub-shell 211. Specifically, the speaker 40 is installed on the fastening column 2112 on the first base sub-shell 211 by fasteners such as screws; the rotating member 23 is rotatably connected to the first bracket arm sub-shell 221. Further, the body shell 10 is installed on the first bracket arm sub-shell 221 by the rotating member 23; based on the fact that the first base sub-shell 211 and the first bracket arm sub-shell 221 are integrally connected, the speaker 40 and the body shell 10 are respectively connected to the same shell (the first bracket sub-shell 201).

[0032] A conductive cable (not shown in the figure) is provided between the body shell 10 and the base shell 21, and a hollow channel is formed between the first bracket arm sub-shell 221 and the second bracket arm sub-shell 222 to lay the conductive cable. Specifically, a wiring groove 2211 is provided on the first bracket arm sub-shell 221, and a hollow wiring hole 231 is provided at the center of the rotating part 23. The hollow wiring hole 231 connects the body shell 10 and the hollow channel. The cables in the body shell 10 extend to the base shell 21 after passing through the hollow wiring hole 231 and the wiring groove 2211. In combination with the aforementioned description, the speaker and the body shell 10 are respectively connected to the same shell (the first bracket sub-shell 201). In this way, during installation, the body shell 10 and the speaker 40 can be first installed on the first bracket sub-shell 201, so that some conductive cables in the projection device pass through the hollow wiring hole 231 provided at the center of the rotating member 23, and then extend along the wiring groove 2211 provided on the first bracket arm sub-shell 221 to the first base sub-shell 211, and are installed to the first bracket arm sub-shell 221 through the cover plate 2212 to confine the conductive cables in the wiring groove 2211, and finally the conductive cables are electrically connected to the speaker 40, and then the first bracket sub-shell 201 and the second bracket sub-shell 202 are assembled and fixed by snap-fit ​​fasteners, and finally the decorative panel 50 is assembled to complete the installation of the entire machine, which can effectively improve the installation efficiency.

[0033] Furthermore, a buffer pad, such as a silicone pad, is provided between the speaker 40 and the first base sub-shell 211 at the connection point through the fastener, which can reduce the transmission of the vibration of the speaker 40 to the body shell 10, and prevent the vibration generated by the speaker 40 when working from being transmitted upward and affecting the optical machine. The speaker 40 and the second base sub-shell 212 are arranged at a distance to form a suspended structure design, so as to prevent the speaker 40 from vibrating and colliding with the second base sub-shell 212 to produce noise. In some embodiments, a buffer pad, such as a foam structure, can also be provided at the interval between the speaker 40 and the second base sub-shell 212.

[0034] In some embodiments, at least one of a microphone module 60, a key module, an antenna module, a power module 70 and a socket module 80 is also provided on the first base sub-shell 211, wherein the microphone module includes a microphone PCB board 51 and a microphone hole 52, the power module 60 adopts a power PCB board, the microphone PCB board 51 and the power PCB board are respectively fixedly arranged in the first base sub-shell 211, the top surface of the first base sub-shell 211 is provided with a sound pickup hole to correspond to the microphone hole 52, and the socket module 80 is arranged on the shell of the first base sub-shell 211 and is electrically connected to the power PCB board. By arranging all these modules in the first base sub-shell 211, the conductive cable routing mode of each component can also be electrically connected to the main control circuit board (not shown) in the fuselage shell 10 after passing through the wiring groove 2211 and the hollow wiring hole 231. The electronic components of these modules are all installed in the first bracket sub-shell 201 like the fuselage shell 10, which is convenient for assembly and cable connection. Among them, the audio 40 is arranged at intervals from the above modules.

[0035] In this embodiment, the rotating member 23 is a damping shaft structure. In some other embodiments, the rotating member 23 can also be a gear-type shaft that can only rotate a fixed small angle each time; or the rotating member 23 can also be a non-damping shaft. After the user manually rotates the fuselage shell 10 to a specific angle, the fuselage shell 10 and the bracket arm shell 22 are locked by the knob structure on the bracket arm shell 22, so that the fuselage shell 1 is fixed to a preset pitch angle; or the rotating member 23 includes a motor drive mechanism and a gear assembly, and the motor drive mechanism cooperates with the gear assembly to connect the fuselage shell or the bracket arm shell 22 to drive the fuselage shell 10 to rotate relative to the bracket arm shell 22.

[0036] In other embodiments, the main control circuit board of the projection device may also be arranged on the first base sub-shell 211, and the optical machine is electrically connected to the main control circuit board in the base shell 21 through cables. For example, the main control circuit board is fixed between the speaker 40 and the top surface of the first base sub-shell 211, and the cable layout rule at this time can be reversed, and the cables of the optical machine, display screen 30, sensor and other components in the body shell 10 are connected to the main control circuit board of the first base sub-shell 211 through the hollow wiring holes 231 and the wiring grooves 2211. By transferring more devices originally located in the body shell 10 to the base shell 21, part of the thickness of the body shell 10 of the projection device can be further transferred to the base shell 21 of the base assembly 20, so that the thickness of the body shell 10 of the projection device becomes thinner, and the projection device displayed with the display screen 30 is closer to the picture frame.

[0037] In some other embodiments, the speaker 40 may also be fixed on the second base sub-shell 212, and the bracket arm shell 22 may also be provided on only one side to form a single-arm support structure, rather than the current double-arm support structure. Since the speaker 40 is separated from the body shell 10, the weight of the body shell 10 of the projection device can be effectively reduced, and the single-arm support structure is also sufficient to support the weight of the body shell 10 and the components therein.

[0038] In the projection device of the preferred embodiment of the utility model, the speaker 40 is not arranged inside the body shell 10, but the speaker 40 is transferred to the base shell 21 of the bracket assembly 10, and only the necessary components such as the optical machine, the display screen 30, the radiator (not shown in the figure), the shooting / depth sensor and part of the circuit board can be retained inside the body shell 10. The speaker 40 in the base shell 21 is connected to the circuit board in the body shell 10 through the conductive cable in the wiring groove 2211 provided on the first bracket arm sub-shell 221 and the hollow wiring hole 231 provided at the center of the rotating member 23, so as to control the speaker 40 in the base shell 21 and transmit the audio signal to it. Since the speaker 40 will produce obvious vibration when the volume is high, the structure in this embodiment can greatly reduce the transmission of the vibration of the speaker 40 to the body shell 10, avoiding affecting the optical machine and causing the picture to shake; wherein, the projection light is emitted from the optical machine, and when the vibration amplitude of the optical machine is too large, the projected picture on the target projection surface will shake significantly, affecting the viewing experience. In addition, the projection device as a whole can present a visual structure similar to a picture frame. On the other hand, the projection device in the embodiment of the present application can make the display screen 30 be easily rotated by means of the bracket assembly 20 to adjust the angle direction, thereby making it convenient for users to watch the content on the display screen 30.
