Technical Field

[0001] The invention relates to the technical field of image projection, and in particular to an image projector with an adjustment structure. Background Art

[0002] The presence of black edges in the projector's playback image does affect the viewing experience. This black edge is usually caused by a mismatch in the aspect ratio, incorrect projector settings, or a resolution problem with the input signal. It will weaken the immersion and visual effects of the image, especially when watching movies or high-resolution content. Therefore, it is necessary to reduce the impact of the black edges on the viewing experience through adjustments.

[0003] The patent with announcement number CN116708728B discloses an LCOS projector calibration and adjustment device and its adjustment method. The device includes a checkerboard support plate group, a support plate, a guide rail, a positioning plate group, an adjustment group, a slide rail fixing plate, an up and down adjustment hand wheel, an up and down adjustment screw, an up and down adjustment screw bracket, an up and down adjustment guide rail, a limiting plate, a slide plate and a front and back adjustment bracket, etc.; the positioning plate group is assembled according to the size of the projector, and the projector is placed on the positioning plate group. The position of the projector is adjusted left and right, up and down, and front and back so that the camera center axis of the projector coincides with the center line of the intersection of the checkerboard support plate group, thereby completing the adjustment of the projector calibration. This patent is highly operational, and the adjustment steps are simple and easy to use. It can flexibly adapt to projectors of different sizes. By adjusting the device, the relative position between the projector and the calibration plate can be flexibly adjusted up and down, left and right, front and back, without the need for multiple calibrations, thereby reducing the workload and improving the calibration efficiency and accuracy. However, there is a problem that the playback part does not match the video resources, and there will be bright light and black edges that affect the viewing experience. Therefore, it is necessary to design an image projector with an adjustment structure. Summary of the invention

[0004] The object of the present invention is to provide an image projector with an adjustment structure to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an image projector with an adjustment structure, comprising a projection end shell, a top cover is fixedly connected to the top of the projection end shell, filters are fixedly connected to the left and right sides of the projection end shell, a flip groove is provided on the top surface of the top cover, a projection integrated module is arranged inside the projection end shell, a reflection module is arranged on the side of the projection integrated module, an imaging seat is fixedly connected to the front side of the reflection module, partitions are arranged on the left and right sides of the reflection module, a projection structure is connected to the front side of the imaging seat, heat dissipation structures are arranged on both sides of the interior of the projection end shell, and a support structure is arranged on the bottom side of the projection end shell;

[0006] The projection structure includes a thin screw, two ends of the front side of the imaging mount are fixedly connected to a sliding rod, the outer side of the sliding rod is slidably connected to a sliding frame, the thin screw is threadedly connected to the middle position of the sliding frame, the bottom surface of the sliding frame is fixedly connected to a pushing groove block, the front side of the imaging mount is rotatably connected to a lens, the outer side of the lens is fixedly connected to an adjusting ring, the outer side of the adjusting ring is provided with an adjusting groove, the end of the sliding rod away from the imaging mount is fixedly connected to a winding end shell, the upper and lower ends of the winding end shell are rotatably connected to a winding roller, the outer side of the winding roller located above is fixedly connected to a pulling wire, the end of the pulling wire away from the winding roller is fixedly connected to a fixing rod, and the outer side of the winding roller is wound A shielding roll is wound around it, and a light-transmitting groove with different aspect ratios is opened on the side of the shielding roll, the partition is rotatably connected to the top cover, one end of the fine screw is rotatably connected to the imaging seat, and the other end of the fine screw is rotatably connected to the winding end shell, the adjusting groove is spiral, and the adjusting groove is slidably connected to the pushing groove block, and a torsion spring is arranged on the side of each winding roller close to the inner wall of the winding end shell, and the two ends of the torsion spring are respectively fixedly connected to the winding end shell and the winding roller, the wire fixing rod is fixedly connected to the slide, and the micro-motor arranged in the imaging seat drives the connected fine screw to rotate, so that the rotation of the fine screw drives the slide to slide along the slide rod, and the movement of the slide drives the connected pushing groove block to rotate along the adjusting groove outside the adjusting ring, and the adjusting ring is adjusted The rotation drives the lens to rotate, and the winding end shell remains stationary with the imaging seat through the sliding rod. The imaging picture is changed from horizontal to vertical through the rotation of the lens, so that when using mobile phones and other smart devices to project the screen, the screen content display can be maximized to improve the viewing experience. At the same time, when the slide frame fixes the projection integrated module along the sliding rod, the ventilation connection connected to the flip ring frame drives the flip frame to rotate around the axis of the side fixing ring, so as to change the lens projection angle by changing the angle of the winding end shell, so as to adjust the projection height on the wall, or project the picture onto the roof, without the need for additional brackets as support adjustment, thereby improving the projection picture angle and range.

In addition, through the rotation of the fan blades, the external structure air enters the side fixed ring from the filter on the left side of the projection end shell and then enters the ventilation tube through the flip frame, allowing the outside air to flow and take away the heat from the upper and lower sides of the projection integrated module and the reflection module through heat transfer. The air is discharged from the right filter through the ventilation tube, so that the air will not directly enter the interior of the projection end shell, thereby preventing dust from entering the projection end shell and avoiding dust adhesion to cause electrostatic short circuit of the built-in circuit board.

The foot supports extend out of the outer wall, and a spring is arranged on the outside of the foot supports, and the two ends of the spring are respectively fixedly connected to the projection end shell and the pressure ring. When the projection end shell is placed on the platform, the foot supports on the bottom side of the projection end shell are in contact with the platform surface. When the platform surface is tilted, the bubble bin in the liquid bin will slide in the liquid bin in the opposite direction of the tilt. The sliding of the bubble bin will drive the connected gas bin connecting rod to push the shaft groove rod. The shaft groove rod is pushed by the gas bin connecting rod to lift the connecting seat connected to the shaft groove rod upward through the foot supports, and when the foot supports move upward, the pressure ring is pulled to pull the spring, and the height of the upward end of the foot supports on the bottom side of the projection end shell will be reduced, thereby adjusting the left and right horizontal heights of the projection end shell to avoid deformation of the projection picture caused by the tilt of the projection end shell, affecting the viewing experience.

The imaging picture is changed from horizontal to vertical by rotating the lens, so that when a mobile phone or other smart device is used for screen projection, the picture displayed on the screen can be maximized to improve the viewing experience. At the same time, the screen aspect ratio of the light-transmitting groove is changed from 4:3 to 16:9, and the screen aspect ratio of 16:9 is used to make the light-transmitting groove shield the bright light around the black edge of the picture, so as to avoid the bright part of the black edge distracting attention and affecting the viewing experience.

[0010] The present invention is provided with a side fixing ring, a brush strip, a brush, a vibration rod, a flip frame, a ventilation tube, a fan blade, a flip ring frame, a connecting rod, a heat dissipation pipe, and a heat dissipation block.

At the same time, the outside air is allowed to flow to take away the heat from the upper and lower sides of the projection integrated module and the reflection module through heat transfer. The air is discharged from the right filter screen through the ventilation tube, so that the air will not directly enter the interior of the projection end shell, thereby preventing dust from entering the projection end shell and preventing dust adhesion from causing an electrostatic short circuit of the built-in circuit board.

[0011] The present invention is provided with a foot support, a pressure ring, a connecting seat, a balancing lever, an axial groove rod, an air chamber connecting rod, an air bubble chamber, and a liquid chamber.

The shaft groove rod 75 is pushed by the gas tank connecting rod 76 to lift the connecting seat 73 connected to the shaft groove rod 75 upward through the foot support 71, and when the foot support 71 moves upward, the spring is pulled by pulling the pressure ring 72, and the height of the upper end of the foot support 71 on the bottom side of the projection end shell 1 will be reduced, thereby adjusting the left and right horizontal heights of the projection end shell 1 to avoid the projection end shell 1 tilting and causing the projection picture to be deformed and affect the viewing experience.

[0026] Working principle: The micro motor provided in the imaging mount 10 drives the connected thin screw 51 to rotate, so that the rotation of the thin screw 51 drives the slide 53 to slide along the slide bar 52, and the movement of the slide 53 drives the connected push slot block 510 to rotate along the adjustment slot 59 on the outer side of the adjustment ring 11, and the lens 511 is driven to rotate by the rotation of the adjustment ring 11. The winding end shell 512 is kept stationary with the imaging mount 10 through the slide bar 52, and the imaging picture is changed from horizontal to vertical through the rotation of the lens 511, so that when using a mobile phone or other smart device to project the screen, the screen content displayed can be maximized to enhance the viewing experience. At the same time, when When the slide 53 moves forward along the slide bar 52 from the back, the pull wire 55 connected to the wire fixing rod 54 on the slide 53 is no longer tight, so that the winding roller 56 reels the shielding film 57 under the action of the torsion spring, so that the light-transmitting groove 58 on the shielding film 57 is reeled in the winding roller 56, and as the shielding film 57 is reeled in, another light-transmitting groove 58 is released from the lower winding roller 56, thereby changing the screen aspect ratio of the light-transmitting groove 58 from 4:3 to 16:9, and using the screen aspect ratio of 16:9 to make the light-transmitting groove 58 block the bright light around the black edge of the screen, so as to avoid the bright part of the black edge distracting attention and affecting the viewing experience;

[0027] By manually adjusting the rotation of the winding end shell 512, the winding end shell 512 is subjected to force through the slide bar 52 to drive the connected imaging seat 10 to be subjected to force, and the imaging seat 10 is subjected to force to drive the reflection module 12 to deflect around the center of the flip ring frame 68. In this process, the connecting rod 69 connected to the flip ring frame 68 fixes the projection integrated module 8, and the ventilation connection tube 66 connected to the flip ring frame 68 drives the flip frame 65 to rotate around the axis of the side fixed ring 61, so as to change the projection angle of the lens 511 by changing the angle of the winding end shell 512, so as to adjust the height of the projection on the wall, or project the picture onto the roof, without the need for additional brackets as support adjustment, to improve the angle and range of the projection picture, and at the same time, the flip frame 65 rotates along the side fixed ring 61, so that the side fixed ring 61 is attached to the side of the filter 3 through the connected brush strip 62 The surface is cleaned by the brush 63 connected to the brush strip 62, and the side of the filter screen 3 is cleaned by the brush 63 connected to the brush strip 62. In addition, the vibration rod 64 connected to the brush strip 62 contacts the filter holes of the filter screen 3, so that the vibration rod 64 moves along the filter screen 3 and vibrates, and the cleaning effect is improved by vibration, so as to prevent dust from blocking the filter screen 3 and affecting the transmission of the sound source of the built-in speaker of the projection end shell 1. In addition, through the rotation of the fan blade 67, the external structure air enters the side fixing ring 61 from the filter screen 3 on the left side of the projection end shell 1 and then enters the ventilation connection 66 through the flip frame 65, so that the outside air flows to take away the heat on the upper and lower sides of the projection integrated module 8 and the reflection module 12 through heat transfer, and the air is discharged from the right filter screen 3 through the ventilation connection 66, so that the air will not directly enter the interior of the projection end shell 1, so as to prevent dust from entering the projection end shell 1 and avoid the static short circuit of the built-in circuit board caused by dust adhesion;

[0028] When the projection end shell 1 is placed on the platform, the foot support 71 at the bottom of the projection end shell 1 contacts the platform surface. When the platform surface is tilted, the bubble chamber 77 in the liquid chamber 78 will slide in the liquid chamber 78 in the opposite direction of the tilt. The sliding of the bubble chamber 77 will drive the connected gas chamber connecting rod 76 to push the shaft groove rod 75. The shaft groove rod 75 is pushed by the gas chamber connecting rod 76 to lift the connecting seat 73 connected to the shaft groove rod 75 upward through the foot support 71, and when the foot support 71 moves upward, the spring is pulled by pulling the pressure ring 72. The height of the upper end of the foot support 71 at the bottom of the projection end shell 1 will be reduced, thereby adjusting the left and right horizontal heights of the projection end shell 1 to avoid deformation of the projection image caused by the tilt of the projection end shell 1 and affecting the viewing experience.
