[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0022] A desktop projector that can adapt to the ambient brightness, such as Figure 1-Figure 4 As shown, it includes a mounting frame 1, a sliding hinged frame 2, a handle 3, a projector 5, a controller 6, a slider 7, a bolt 71, a slide rail 8, a reflector 9 and a condenser 10. The front and rear sides of the mounting frame 1 are slidably connected to the sliding hinged frame 2 through damping plates. The handle 3 is fixed to the top of the mounting frame 1. The projector 5 is rotatably connected between the front and rear sliding hinged frames 2 through a damping ring. The left side of the projector 5 is fixed and electrically connected to the controller 6. The right side of the projector 5 is fixed to the outside of the slide rail 8. The outside of the slide rail 8 is slidably connected to the slider 7. The front side of the slider 7 is threadedly connected to a bolt 71, and the bolt 71 is squeezed into fit with the projector 5. The right side of the slider 7 is fixed to the reflector 9, and the right side of the reflector 9 is fixed to the condenser 10.

[0023] like Figure 2 As shown, a level 4 is also included, and the level 4 is fixedly connected to the middle part of the lower side of the mounting frame 1.

[0024] like Figure 3As shown, a brightness sensor 11 is also included. The brightness sensor 11 is fixedly connected to the upper right side of the condenser lens 10 , and the brightness sensor 11 is electrically connected to the controller 6 .

[0025] like Figure 6 As shown, a voice recognizer 14 is also included. The voice recognizer 14 is fixedly connected to the upper side of the inner wall of the projector 5 , and the voice recognizer 14 is electrically connected to the controller 6 .

[0026] When people want to use the projector 5 to watch film and television works indoors, they can first place the mounting frame 1 and the projector 5 and other components on the desktop through the handle 3. At this time, they can observe the level 4 and adjust the position of the mounting frame 1 and other components to ensure that the projector 5 is in a horizontal state, so as to ensure the subsequent viewing experience. They can also move the sliding hinged frame 2 and the projector 5 and other components up and down to adjust the height, and adjust the projection angle by rotating the projector 5 and other components. After the adjustment is completed, the user can watch the corresponding film and television works through the projector 5. During this period, the user can manually operate the controller 6 to adjust the volume, brightness and playback content of the projector 5, etc., and can also use the voice recognition device 14 to voice control and adjust the controller 6 and the projector 5, which is very simple and convenient. When the indoor environment brightness is low, the reflector 9 and the condenser 10 and other components can be moved to the right and away from the light source of the projector 5, so as to reduce the projection brightness and increase the projection range, thereby improving the user's viewing experience. When the indoor environment brightness is medium, the brightness sensor 11 will monitor the external environment brightness and increase the brightness of the projector 5 light source through the controller 6 to ensure that the user can still see the projected content clearly. When the indoor environment brightness is high and the brightness adjustment function of the projector 5 itself cannot adapt to the external environment, the reflector 9, the condenser 10 and other components can be moved to the left and close to the projector 5 light source. The reflector 9 and the condenser 10 can be used to concentrate the light, thereby further improving the projection brightness and narrowing the projection range to a certain extent, ensuring that the projected content is clear enough even in strong light. In this way, the projector 5 can adapt to different ambient brightness and ensure that the user can see the projected content clearly in various brightness environments. After adjusting the position of the reflector 9 and the condenser 10, the bolt 71 can be turned forward to move the bolt 71 backward and squeeze the projector 5, thereby fixing the reflector 9 and the condenser 10. When it needs to be moved again, just turn the bolt 71 in the opposite direction to unlock it. Example 2

[0027] On the basis of Example 1, Figure 5 and Figure 6 As shown, it also includes a fan 12, a temperature control plate 13 and a sliding plate 15. The fan 12 is fixed to the upper part of the mounting frame 1, the temperature control plate 13 is fixed to the lower side of the inner wall of the projector 5, and the sliding plate 15 is slidably connected to the left side of the projector 5.

[0028] like Figure 5 As shown, a screw is threadedly connected to the rear side of the sliding plate 15 , and the screw is squeezed into the projector 5 , and the screw is used to fix the sliding plate 15 .

[0029] When the projector 5 is overheated due to long-term use, the temperature control plate 13 and the fan 12 can be started to cool down and dissipate heat for the projector 5. At this time, the vents of the projector 5 are in an open state, which can increase the heat dissipation rate. When the projector 5 is not used for a long time, the sliding plate 15 can be moved to the left and the vents can be blocked to prevent dust accumulation or even damage inside the projector 5. After the sliding plate 15 is moved, it can also be limited and fixed by rotating the screw forward. When it needs to be moved again, the screw can be rotated in the reverse direction to unlock it.
