Description

Technical Field

[0001] The utility model relates to a projector, in particular to a projector capable of automatically correcting a lens. Background Art

[0002] A projector, also known as a projector, can convert electronic images or video signals into light signals, amplify them through an optical system, and finally project them onto a screen or wall. Projectors are widely used in homes, offices, schools, and entertainment venues. They are used to enlarge images onto a screen or wall for easy viewing.

[0003] Before using the projector, you need to turn it on to check whether the projected image is clear and level. If not, you need to adjust the projector, such as raising it, tilting it, etc. However, despite the adjustments, it is often impossible to adjust to the optimal state due to inappropriate angles or objects used for padding.

[0004] How to design a projector that can automatically correct the lens has become a problem that needs to be solved at present. Utility Model Content

[0005] In order to overcome the disadvantages that the projector needs to be turned on to check whether the projected image is clear and level before use, and to make adjustments, but often cannot be adjusted to the best state due to angles and other reasons, the utility model provides a projector with automatic lens correction.

[0006] The technical solution of the utility model is as follows: a projector capable of automatically correcting a lens comprises a projector body, a support frame, an electric slide rail, an electric slider and a lens. The support frame is installed on the projector body, and the electric slide rail is symmetrically and rotatably installed in the support frame. The electric slide rail is arc-shaped, and the electric slider is slidably connected in the electric slide rail. The two electric sliders are commonly connected to the lens, and the lens is connected to the projector body.

[0007] Further description, it also includes a motor, the motor is installed on the side of the support frame, and the output shaft of the motor is connected to one of the electric slide rails through a coupling.

[0008] Further description, it also includes a heat sink and an electric fan. The heat sink is arranged on the side of the lens, and the electric fan is installed at the end of the heat sink away from the lens.

[0009] Further description, it also includes a protective net, which is installed on the outside of the electric fan.

[0010] Further description, it also includes a support rod and a rotating cover. The support rod is installed on the side of the lens, and the outer side of the support rod is connected to the rotating cover. The rotating cover movably covers the outer side of the lens.

[0011] Further description, it also includes a magnet block, the side of the lens is equipped with a magnet block, and the magnet block is movably magnetically adsorbed to the rotating cover.

[0012] Further description, it also includes an anti-sliding block, and a plurality of anti-sliding blocks are installed at the bottom of the projector body.

[0013] The beneficial effect of the utility model is that the image of the projector body is projected onto the screen through the lens. If the image is tilted, the electric slide rail moves the electric slider, and the electric slider rotates the lens to adjust the tilted image to a horizontal level, thereby achieving the effect of automatically correcting the lens.

[0023] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0024] Example 1

[0025] A projector with an automatically corrected lens, such as Figure 1-Figure 8 As shown, it includes a projector body 1, a support frame 2, a motor 3, an electric slide rail 4, an electric slider 5 and a lens 6. The support frame 2 is installed on the projector body 1, and the electric slide rail 4 is symmetrically and rotatably installed in the support frame 2. The electric slide rail 4 is arc-shaped, and the electric slider 5 is slidably connected in the electric slide rail 4. The two electric sliders 5 are commonly connected to the lens 6, and the lens 6 is connected to the projector body 1. The motor 3 is installed on the side of the support frame 2, and the output shaft of the motor 3 is connected to one of the electric slide rails 4 through a coupling.

[0026] When the projector body 1 needs to be used, the projector body 1 is turned on, and the image in the projector body 1 is projected onto the screen through the lens 6. The lens 6 is adjusted according to the image on the screen. If the image on the screen is not on a horizontal plane, the electric slide rail 4 works to drive the electric slider 5 to rotate along the electric slide rail 4, and the electric slider 5 rotates with the lens 6. The effect of the adjustment is understood by observing the screen, which plays a role in fine decoration regulation. If the height of the image needs to be adjusted, the motor 3 works to drive the electric slide rail 4 to rotate, and the electric slide rail 4 rotates with the electric slider 5 and the lens 6 to achieve the effect of adjusting the height.

[0027] Example 2

[0028] On the basis of Example 1, Figure 1 , Figure 2 and Figure 3 As shown, it also includes a heat sink 7, an electric fan 8, a protective net 9, a support rod 10, a rotating cover 11, a magnet block 12 and an anti-sliding block 13. The heat sink 7 is arranged on the side of the lens 6, and the electric fan 8 is installed at the end of the heat sink 7 away from the lens 6. The electric fan 8 plays a role in heat dissipation. The protective net 9 is installed on the outside of the electric fan 8, and the support rod 10 is installed on the side of the lens 6. The rotating cover 11 is connected to the outside of the support rod 10. The rotating cover 11 movably covers the outside of the lens 6. A magnet block 12 is installed on the side of the lens 6. The magnet block 12 and the rotating cover 11 are movably magnetically adsorbed. The rotating cover 11 plays a role in protecting the lens 6. A plurality of anti-sliding blocks 13 are installed at the bottom of the projector body 1.

[0029] When the lens 6 is working, heat is generated, and the heat is transferred to the heat sink 7. The electric fan 8 is working, and the wind blown out blows away the heat in the heat sink 7 to play a heat dissipation role. When the lens 6 is at rest, the rotating cover 11 is rotated, and the rotating cover 11 is close to the magnet block 12. The magnet block 12 and the rotating cover 11 have magnetic forces against each other, and the rotating cover 11 covers the outside of the lens 6 to protect the lens 6.

[0030] It should be understood that the above description is only for exemplary purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
