[0035] Embodiment:

[0036] As Figure 1-10 shown, this embodiment proposes a new type of automatic adjustment projector, including a projector body 10, and an installation frame 20 is provided on the projector body 10;

[0037] Two groups of mounting plates 21 are provided on the mounting frame 20, a fixing component 30 is provided between the two groups of mounting plates 21, an adjusting gear 60 is rotatably provided on the mounting plate 21, the adjusting gear 60 cooperates with the fixing component 30, a bottom plate 22 is provided on the mounting frame 20, a driving motor 50 is provided on the bottom plate 22, a driving gear 51 is provided on the rotating shaft of the driving motor 50, the driving gear 51 meshes with the adjusting gear 60, and the driving gear 51 drives the adjusting gear 60 to rotate, so that the fixing component 30 rotates to adjust the elevation angle of the projector body 10.

[0038] In this case, the driving motor 50 is a servo motor, which will not be elaborated here.

[0039] In this embodiment, when automatically adjusting the projector body 10, the projector body 10 is installed on the fixing component 30, and then the driving motor 50 is turned on. Through the meshing of the driving gear 51 and the adjusting gear 60, the adjusting gear 60 rotates, and the fixing component 30 is driven to rotate by the adjusting gear 60, so that the elevation angle of the projector body 10 is changed, and the automatic adjustment process of the projector body 10 is completed;

[0040] Through the cooperation between the driving gear 51, the adjusting gear 60 and the fixing component 30, it is convenient to automatically adjust the elevation angle of the projector body 10, the projection angle of the projector body 10 can be perfectly matched with the screen, so as to obtain the best viewing effect. At the same time, the user does not need to manually adjust the elevation angle, reducing the operation complexity, greatly improving the practicability and convenience of the projector, making the projector more intelligent and meeting the needs of modern users for efficient and convenient operations.

[0041] Specifically, the fixing component 30 includes two groups of fixing gears 31, and a rotating rod 35 is provided on the fixing gear 31;

[0042] A rotation hole 23 is formed in the mounting plate 21, the rotating rod 35 is rotatably arranged in the rotation hole 23, the adjustment gear 60 meshes with the fixed gear 31, and when the adjustment gear 60 rotates, it drives the fixed gear 31 to rotate around the axis of the rotating rod 35 to adjust the elevation angle of the projector body 10.

[0043] Specifically, a fixing plate 32 is arranged between the two groups of fixed gears 31, and a fixing through groove 34 is formed in the fixing plate 32;

[0044] The projector body 10 is connected to the fixing through groove 34 by bolts.

[0045] In this embodiment, when the projector body 10 automatically adjusts, the adjustment gear 60 rotates to drive the fixed gear 31 to rotate, so that the fixed gear 31 rotates around the axis of the rotating rod 35, thereby driving the projector body 10 on the fixing plate 32 to rotate and adjusting the elevation angle of the projector body 10;

[0046] Certainly, the fixing through groove 34 facilitates the installation of the projector body 10 and subsequent maintenance of the projector body 10.

[0047] Specifically, an adjustment hole 25 is formed in the mounting plate 21, an adjustment rod 61 is arranged on the adjustment gear 60, the adjustment gear 60 is rotatably arranged on the adjustment rod 61, and the adjustment rod 61 is slidably arranged in the adjustment hole 25;

[0048] The displacement of the adjustment rod 61 in the adjustment hole 25 enables the adjustment gear 60 to mesh with the fixed gear 31 and the driving gear 51.

[0049] In this embodiment, when it is necessary to mesh the adjustment gear 60 with the driving gear 51 and the fixed gear 31, the adjustment gear 60 is pushed towards the mounting plate 21 and the fixed gear 31 and the driving gear 51 are rotated until the adjustment gear 60 is caught between the fixed gear 31 and the driving gear 51.

[0050] Specifically, an adjustment sleeve 62 is arranged on the adjustment rod 61;

[0051] An adjustment spring 64 is sleeved on the outer wall of the adjustment rod 61, and the adjustment spring 64 is connected between the adjustment sleeve 62 and the mounting plate 21.

[0052] Specifically, a limiting block 27 is arranged in the adjustment hole 25, a limiting groove 65 is formed in the adjustment rod 61, and the limiting block 27 is slidably arranged in the limiting groove 65;

[0053] An adjustment connection hole 63 is provided on the adjustment sleeve 62, and a limit connection hole 26 is provided on the limit block 27. The positions and sizes of the adjustment connection hole 63 and the limit connection hole 26 match. The adjustment connection hole 63 and the limit connection hole 26 are connected by bolts, so that the adjustment gear 60 is not engaged with the fixed gear 31 and the driving gear 51.

[0054] In this embodiment, when it is not necessary for the adjustment gear 60 to be engaged with the fixed gear 31 and the driving gear 51, the adjustment sleeve 62 is pushed towards the mounting plate 21 to displace, so that the adjustment gear 60 disengages from between the fixed gear 31 and the driving gear 51, and a bolt can be installed between the adjustment connection hole 63 and the limit connection hole 26.

[0055] Of course, when the adjustment sleeve 62 is displaced towards the mounting plate 21, the adjustment spring 64 is compressed. When the adjustment gear 60 needs to be engaged with the fixed gear 31 and the driving gear 51, the bolt between the adjustment connection hole 63 and the limit connection hole 26 is removed, and the adjustment spring 64 resets, driving the adjustment gear 60 to displace towards the mounting plate 21. After that, only the fixed gear 31 and the driving gear 51 need to be rotated, and under the reset pulling force of the adjustment spring 64, it is convenient for the adjustment gear 60 to be caught between the fixed gear 31 and the driving gear 51.

[0056] Through the above position transformation of the adjustment gear 60, it is convenient to change the adjustment method of the projector body 10 between automatic adjustment and manual adjustment, which is convenient for use according to the actual situation and improves the overall practicality.

[0057] Specifically, a protective housing 40 is provided on the bottom plate 22, and a plurality of protective connection holes 41 are provided on the protective housing 40.

[0058] A plurality of mounting connection holes 24 are provided on the mounting plate 21. The positions and sizes of the plurality of mounting connection holes 24 match those of the plurality of protective connection holes 41, and the mounting connection holes 24 and the protective connection holes 41 are connected by bolts.

[0059] In this embodiment, the provided protective housing 40 can facilitate the protection of the drive motor 50.

[0060] Specifically, an anti-slip rubber ring 28 is provided on the mounting plate 21, and the anti-slip rubber ring 28 matches the rotation hole 23 in position.

[0061] An anti-slip threaded hole 311 is provided on the fixed gear 31, and an anti-slip bolt 33 is threadedly arranged in the anti-slip threaded hole 311. The anti-slip bolt 33 contacts the anti-slip rubber ring 28 to limit the fixed gear 31.

[0062] In this embodiment, when the projector body 10 is manually adjusted, the contact between the anti-slip bolt 33 and the anti-slip rubber ring 28 can limit the fixed gear 31. Thus, after the fixed gear 31 is rotated and adjusted, the stability of the fixed gear 31 can be ensured, and thereby the stability of the projector body 10 can be ensured.

[0063] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
