At this time, the display screen 21 faces the detection direction; Figure 4 The rotating assembly 12 includes a driving unit 121 and a rotating chassis unit 122. The driving unit 121 is connected to the rotating chassis unit 122, and the driving unit 121 is fixedly arranged on the bracket assembly 11 to drive the bracket assembly 11 and the projector body 20 to rotate relative to the rotating chassis unit 122 with the vertical direction as the axis.

[0028] The bracket assembly 11 also includes a base 112, a bracket 113 and a rotating member 114. The bracket 113 is fixed to the base 112. The reflector 111 is arranged on the base 112 and / or the bracket 113. The rotating member 114 is rotatably connected to the bracket 113. The rotating member 114 is used to connect the projector body 20 so that the projector body 20 can rotate relative to the bracket 113 along with the rotating member 114, and the axial direction of the rotation of the rotating member 114 relative to the bracket 113 is parallel to the reflecting surface of the reflector 111.

[0029] In this embodiment, the bracket 113 includes a bracket arm 1131 and a connecting arm 1132, the bracket arm 1131 is connected to the base 112, the rotating member 114 is rotatably connected to the bracket arm 1131, and the connecting arm 1132 is connected to the side of the bracket arm 1131 away from the base 112.

Specifically, the reflective surface of the first reflector is disposed at an angle of 45° to the bottom surface of the base 112, that is, the reflective surface of the first reflector is at an angle of 45° to the horizontal plane. In one example, the light sensor 22 can rotate with the projector body 20 so that the axial direction of the light sensor 22 can form an angle of 45° with the reflective surface of the reflector 111.

[0031] In which, when the bracket 113 includes a connecting arm 1132, the reflector 111 may only include a first reflector arranged on the top of the base 112, or only include a second reflector arranged on a side of the connecting arm 1132 close to the base 112, or may include both the first reflector and the second reflector.

[0032] In some embodiments, the reflector 111 is detachably mounted on the base 112 and / or the bracket 113 .

[0036] Based on the fact that TOF or a camera can be used to determine whether the user is at the position where the display screen 21 is facing, a processor (such as a control chip) is further provided in the projector body 20, and the processor is electrically connected to the light sensor 22 (TOF or camera) and the drive motor 1211 at the same time. The processor obtains the position of the user in the depth detection image or the captured image detected by the TOF or camera, determines the orientation (left or right) relative to the vertical center line of the depth detection image or the captured image, and then outputs an instruction to the drive motor 1211 to gradually rotate the projector body 20 in the above orientation direction (left or right) until the user is at the vertical center position of the depth detection image or the captured image, so as to ensure that the display screen 21 is facing the user. This function can be run in real time and follow the user's movement in real time; or it can be executed after the user triggers the instruction through voice, remote control buttons, etc., so that the user is in the middle of the depth detection image or the captured image.

The retaining groove 12224 is an annular groove. The bearing 1224 is disposed between the rotating chassis 1221 and the bottom surface of the base 112.

Specifically, the positioning block 12221 includes two rectangular blocks protruding upward from the top of the fixing column 1222, and the distribution of the blocks at the top of the fixing column 1222 is a non-circularly symmetrical structure, so that when the driving motor 1211 drives the output gear 1212 to rotate, and the output gear 1212 drives the transmission gear 1231 to rotate, the groove wall of the positioning groove 12311 of the transmission gear 1231 can transmit the force to the positioning block 12221, so that the projector body 20 and the bracket assembly 11 rotate relative to the chassis unit 122; the fastener 12222 is a screw, and the first fixing hole 12223 is a threaded hole, and is opened between the two blocks; correspondingly, the positioning groove 12311 is a rectangular groove, and the second fixing hole 12312 is a circular through hole formed in the middle of the rectangular groove.
