[0029] Referring to Figure 1 and Figure 2 , a projector with adjustable multi-angle support includes a projection main body 1, and further includes an adjustable support structure 2 disposed on the projection main body 1. The adjustable support structure 2 is disposed at the bottom of the projection main body 1. Through the adjustable support structure 2, the projection main body 1 can be supported at different angles, so as to meet the needs of the orientation of the projection main body 1.

[0030] Specifically, the projection main body 1 is a projector. One side in the length direction of the projection main body 1 is the interface area, and the other side in the length direction of the projection main body 1 is the projection area. In order to adapt to the installation of the adjustable support structure 2, the bottom of the projection main body 1 has an adaptation installation area 11 for installing the adjustable support structure 2, and the adaptation installation area 11 has a bracket connection hole 111 for installing a bracket. At the same time, two bottom stoppers 12 are respectively arranged in the width direction of the projection main body 1, and the adjustable support structure 2 is installed between the two bottom stoppers 12, and the adjustable support structure 2 can be installed and protected through the bottom stoppers 12.

[0031] Referring to Figure 3 and Figure 4 , the adjustable support structure 2 includes a rotating shaft assembly 21, a first rotating plate 22 and a second rotating plate 23 connected to the adaptation installation area 11. The rotating shaft assembly 21, the first rotating plate 22 and the second rotating plate 23 are arranged between the bottom stoppers 12. The rotating shaft assembly 21 includes a first limiting rotating shaft 211 and a second limiting rotating shaft 212 arranged coaxially. The first limiting rotating shaft 211 includes a first installation hinge 2111 and a first limiting block 2112 arranged on the first installation hinge 2111. The second limiting rotating shaft 212 includes a second installation hinge 2121 and a second limiting block 2122 arranged on the second installation hinge 2121. In order to install the first limiting rotating shaft 211 and the second limiting rotating shaft 212, the bottom stopper 12 is provided with a bottom installation groove 121. Correspondingly, the first installation hinge 2111 has a first installation block, and the second installation hinge 2121 has a second installation block. The first installation block and the second installation block are passed through the bottom installation groove 121 and then connected to the projection main body 1 for fixation.

[0032] Referring to Figure 3 , Figure 5 and Figure 6 , the first limiting block 2112 is sleeved and fixed on the first installation hinge 2111. One end in the length direction of the first limiting block 2112 has a first limiting groove 21121, and the other end in the length direction of the first limiting block 2112 has a first limiting convex block 21122. The first limiting groove 21121 is used for limiting the first rotating plate 22 when it rotates in place, and the first limiting convex block 21122 is used for limiting the rotation stroke of the second rotating plate 23. The second limiting block 2122 is sleeved and fixed on the second installation hinge 2121. One end in the length direction of the second limiting block 2122 has a second limiting groove 21221, and the second limiting groove 21221 is used for limiting the second rotating plate 23 when it rotates in place.

[0033] The first rotating plate 22 is rotatably connected to the first limiting block 2112, and the second rotating plate 23 is rotatably connected to the second limiting block 2122. Specifically, the first rotating plate 22 has a first rotating portion 221. The axis of the first rotating portion 221 coincides with the axis of the rotating shaft assembly 21. A first abutting swing block 2211 is provided in the first rotating portion 221. The first abutting swing block 2211 has a first abutting block that abuts against the first limiting block 2112. The first abutting block is engaged with or disengaged from the first limiting groove 21121. The first rotating portion 221 is rotatably connected to the first mounting hinge 2111. When the first rotating portion 221 rotates, the first rotating portion 221 will drive the first abutting block to rotate, so as to drive the first abutting block to be engaged with or disengaged from the first limiting groove 21121. After the first abutting block is disengaged from the first limiting groove 21121, the first abutting block will abut against the first limiting block 2112, thereby having a damping effect, so that the first rotating plate 22 can stop and be fixed at any position.

[0034] Similarly, the second rotating plate 23 has a second rotating portion 231. A second abutting swing block 2312 is provided in the second rotating portion 231. The second abutting swing block 2312 has a second abutting block that abuts against the second limiting block 2122. The second abutting block is in contact with or disengaged from the second limiting groove 21221. The second rotating portion 231 is rotatably connected to the second mounting hinge 2121. When the second rotating portion 231 rotates, the second rotating portion 231 will drive the second abutting block to rotate, so as to drive the second abutting block to be engaged with or disengaged from the second limiting groove 21221. After the second abutting block is disengaged from the second limiting groove 21221, the second abutting block will abut against the second limiting block 2122, thereby having a damping effect, so that the second rotating plate 23 can stop and be fixed at any position.

[0035] In order to limit the maximum rotation stroke of the second rotating plate 23, a second limiting swing block 2311 is further provided on the second rotating portion 231. The second limiting swing block 2311 has a second limiting ring groove 23111. The first limiting convex block 21122 is engaged with the second limiting ring groove 23111 and can slide along the second limiting ring groove 23111. When the second rotating plate 23 rotates, the second rotating portion 231 will drive the second limiting swing block 2311 to rotate, so that the second limiting ring groove 23111 moves relative to the first limiting convex block 21122. When the second rotating plate 23 rotates to the stroke limit, the first limiting convex block 21122 will abut against one end in the length direction of the second limiting ring groove 23111, thereby limiting the further rotation of the second rotating plate 23.

[0036] Refer to Figure 1 、 Figure 2 and Figure 7, under the action of the rotating shaft assembly 21, the first rotating plate 22 and the second rotating plate 23 can rotate arbitrarily and can stop at any angle. By adjusting the angle between the first rotating plate 22 and the second rotating plate 23, the projector can be supported, so as to meet the need for a larger projection range. In order to increase the friction and protect the rotating plate, the first rotating plate 22 further includes a first protective sleeve 222, and the first protective sleeve 222 is arranged on the first rotating part 221; the second rotating plate 23 further includes a second protective sleeve 232, and the second protective sleeve 232 is arranged on the second rotating part 231. At the same time, the fitting installation area 11 is also provided with a fastening groove 112, and the fastening groove 112 is located on one side of the first rotating plate 22 and the second rotating plate 23. Through the fastening groove 112, the second rotating plate 23 can be conveniently contacted for driving. At the same time, heat dissipation holes are provided in the fastening groove 112 to discharge the heat generated when the projector operates.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0038] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
