Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens XY direction adjustment technology, and in particular to a lens XY bidirectional movement module. Background Technology
[0002] A projector, also known as a projector, is a device that projects images or videos onto a screen. It can be connected to computers, VCD players, DVD players, BD players, game consoles, DV players, etc., through different interfaces to play corresponding video signals.
[0003] When using existing projectors, if the projector is not directly facing the screen, trapezoidal distortion may occur, requiring trapezoidal correction. If the projector is not installed correctly or the screen shape is irregular, the lens needs to be moved and adjusted in the XY direction. However, lenses usually do not have XY direction adjustment capabilities, which may cause image shift or distortion, resulting in inaccurate display. To address this, we propose a lens XY bidirectional movement module. Utility Model Content

[0037] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0038] Example:
[0039] like Figures 1-5 As shown, a lens XY bidirectional movement module includes:
[0040] Mounting base 1 has a through groove at its bottom, a mounting hole in the Y direction inside its interior, and a fixed mounting through hole inside its interior.
[0041] The movable mounting mechanism 2 is movably located inside the mounting base 1, with a through groove at its bottom and a mounting hole in the X direction inside.
[0042] The fixed limiting block 3 is fixedly installed on the inner right end and front end of the movable mounting mechanism 2;
[0043] The limiting baffle 4 is bolted to the outside of the mounting base 1, and its position corresponds to the fixed mounting through hole.
[0044] The Y-direction adjustment mechanism 5 and the X-direction drive mechanism 6 are movably located inside the limit baffle 4 and inside the fixed mounting through hole inside the mounting base 1.
[0045] The X-direction adjustment mechanism 7 is movably located inside the mounting base 1 and inside the front end of the movable mounting mechanism 2;
[0046] Foam 8 is glued to both the inner and outer bottom ends of the movable mounting mechanism 2.
[0047] The working principle of the above technical solution is as follows:
[0048] During use, the Y-direction adjustment mechanism 5 can be rotated and adjusted, allowing the movable mounting mechanism 2 to move back and forth in the Y direction. The X-direction drive mechanism 6 can be rotated and adjusted, which can drive the X-direction adjustment mechanism 7 to rotate, allowing the movable mounting mechanism 2 to move back and forth in the X direction. The overall structure is simple and the operation is convenient and quick.
[0049] In another embodiment, such as Figure 2 As shown, the movable mounting mechanism 2 includes a movable base frame 21. First through slots 22 are provided in the middle right side, the middle front side, and inside the fixed limiting block 3 of the movable base frame 21. Second through slots 23 are symmetrically provided on both the left and right sides of the movable base frame 21. A Y-direction guide shaft 24 is movably connected to the inner side of the second through slot 23. Both ends of the Y-direction guide shaft 24 are located inside the mounting holes in the Y direction inside the mounting base 1. A first limiting end plate 25 is fixedly connected to one end of the Y-direction guide shaft 24, and a first E-ring 26 is movably engaged on the outer surface of the other end of the Y-direction guide shaft 24. A movable slider 27 is movably sleeved on the outer side of the movable slider 27. An X-direction guide shaft 210 is movably connected inside the movable slider 27 and the movable base frame 21. The X-direction guide shaft 210 is located inside the mounting hole in the X direction inside the movable base frame 21. A second limiting end plate 211 is fixedly connected to one end of the X-direction guide shaft 210. A second E-ring 212 is movably snapped onto the outer side of the other end of the X-direction guide shaft 210. A connecting top block 28 is fixedly connected to the top of the movable slider 27. A connecting cover plate 29 is placed on the top of the connecting top block 28. The connecting cover plate 29 and the connecting top block 28 are connected by bolts.
[0050] When the Y-direction adjustment mechanism 5 is rotated, the movable bottom frame 21 can move to the outside of the surface of the Y-direction guide shaft 24 for adjustment. When the X-direction drive mechanism 6 and the X-direction adjustment mechanism 7 are rotated, the movable bottom frame 21 can move to the outside of the surface of the Y-direction guide shaft 24 under the action of the second through groove 23 for adjustment, which is convenient to operate.
[0051] In another embodiment, such as Figure 4 As shown, the Y-direction adjustment mechanism 5 includes a first rotary adjustment knob 51 located inside the fixed mounting through hole inside the mounting base 1 and inside the first through groove 22 on the right side inside the movable base frame 21. One side of the first rotary adjustment knob 51 is connected to a first threaded adjustment rod 52 via a connecting rod. A limit ring is fixedly sleeved on the outer surface of the connecting rod. The limit ring is located inside the limit baffle 4. A first moving plate 53 is threadedly connected to the outer surface of the first threaded adjustment rod 52. The first moving plate 53 is in contact with the inner side of the fixed limit block 3 located on the right side inside the movable base frame 21.
[0052] This allows the first rotary adjustment knob 51 to be rotated, which in turn rotates the connecting rod and the first threaded adjustment rod 52, enabling the first moving plate 53 to move on the outer side of the surface of the first threaded adjustment rod 52. When the fixed limit block 3 is pushed, the movable base frame 21 is moved, or the movable base frame 21 is pulled directly to perform movement adjustment.
[0053] In another embodiment, such as Figure 5 As shown, the X-direction drive mechanism 6 includes a second rotary adjustment knob 61 fixedly mounted inside the through hole of the mounting base 1. A fixed connecting rod 62 is fixedly connected to one side of the second rotary adjustment knob 61. A limit ring is fixedly sleeved on the outer surface of the fixed connecting rod 62. The limit ring is located inside the limit baffle 4. A first bevel gear 63 is fixedly connected to the end of the fixed connecting rod 62 away from the second rotary adjustment knob 61.
[0054] The second rotary adjustment knob 61 is easy to rotate, which drives the fixed connecting rod 62 and the first bevel gear 63 to rotate, so that the first bevel gear 63 can drive the X-direction adjustment mechanism 7, making operation convenient.
[0055] In another embodiment, such as Figure 5 As shown, the X-direction adjustment mechanism 7 includes a movable connecting rod 71 located inside the movable base frame 21 and inside the front first through groove 22. One end of the movable connecting rod 71 is fixedly connected to a second bevel gear 72, and the other end of the movable connecting rod 71 is fixedly connected to a second threaded adjusting rod 73. The outer surface of the second threaded adjusting rod 73 is threadedly connected to a second moving plate 74. The second moving plate 74 is in contact with the inner side of the fixed limiting block 3 located at the front end inside the movable base frame 21.
[0056] When the first bevel gear 63 rotates, it can drive the second bevel gear 72, the movable connecting rod 71, and the second threaded adjusting rod 73 to rotate, so that the second moving plate 74 can move on the outer side of the surface of the second threaded adjusting rod 73. When the fixed limiting block 3 is pushed, it drives the movable bottom frame 21 to move, or directly pulls the movable bottom frame 21 to make movement and adjustment.
[0057] In another embodiment, such as Figure 5 As shown, the second bevel gear 72 and the first bevel gear 63 are meshed together.
[0058] This facilitates stable transmission between the first bevel gear 63 and the second bevel gear 72, and makes operation convenient.
[0059] In another embodiment, such as Figure 1 As shown, the bottom end of the movable base frame 21 and the inner bottom end of the mounting base 1 slide against each other.
[0060] The movable base frame 21 can be moved stably inside the mounting base 1 when it is moved, making it easy to operate.
[0061] The working principle of this utility model is as follows: First, the entire assembly is completed. The lens is then installed inside the movable base frame 21. When adjustment of the lens in the XY direction is required, the first rotary adjustment knob 51 is rotated, causing the connecting rod and the first threaded adjustment rod 52 to rotate. This allows the first moving plate 53 to move outside the surface of the first threaded adjustment rod 52, pushing the fixed limiting block 3 or pulling the movable base frame 21. This causes the movable base frame 21, movable slider 27, connecting top block 28, connecting cover plate 29, X-direction guide shaft 210, second limiting end plate 211, second E-ring 212, and lens to move, thereby adjusting the lens position. Then, the second rotary adjustment knob 61 is rotated... The rotation causes the fixed connecting rod 62 and the first bevel gear 63 to rotate, which in turn drives the second bevel gear 72 to rotate, which in turn drives the movable connecting rod 71 and the second threaded adjusting rod 73 to rotate. This allows the second moving plate 74 to move on the outer side of the surface of the second threaded adjusting rod 73, pushing the fixed limiting block 3 or pulling the movable bottom frame 21. This causes the movable bottom frame 21, movable slider 27, connecting top block 28, connecting cover plate 29, X-direction guide shaft 210, second limiting end plate 211, second E-ring 212, and lens to move. At this time, the movable bottom frame 21 can move on the outer side of the surface of the Y-direction guide shaft 24 under the action of the second through groove 23, thereby adjusting the position of the lens. The overall structure is simple and the operation is convenient and quick.
[0062] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
