Specifically, a motion bracket is installed in front of the projector, and the 3D modulator is mounted on the motion bracket. The motion bracket moves left and right or up and down to move the 3D modulator relative to the projector lens, thus achieving the conversion between 2D and 3D projection. However, the movement of the motion bracket often relies on a track structure. Furthermore, due to the large number of projector models, the structure of the motion bracket is often quite complex in order to accommodate different projector models.
[0003] Therefore, there is an urgent need for a 3D modulator mounting bracket that is simple in structure and highly adaptable. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] The purpose of this invention is to provide a 3D modulator mounting bracket that, through a hinged structure, allows for adjustment of the perpendicularity between the 3D modulator and the projection light, simplifying the structure of the 3D modulator mounting bracket while ensuring its adaptability.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] refer to Figure 1-5The 3D modulator mounting bracket disclosed in this embodiment includes: a 3D modulator 1, a rotary motor 2, a connecting rod 3, and a support rod 4. The 3D modulator 1 is connected to the output shaft of the rotary motor 2. The rotary motor 2 is mounted on the first end of the connecting rod 3. The second end of the connecting rod 3 is connected to the first end of the support rod 4. The second end of the support rod 4 is mounted on the top of the projector 5. A hinge structure is provided between the connecting rod 3 and the support rod 4 and / or between the connecting rod 3 and the rotary motor 2. The relative angle between the connecting rod 3 and the support rod 4 and / or between the connecting rod 3 and the rotary motor 2 can be adjusted through the hinge structure, thereby adjusting the perpendicularity of the projection light of the 3D modulator 1 and the projector 5, so that the 3D modulator 1 can be used in various applications. When used with projector 5, the 3D modulator 1 can maintain a perpendicular alignment with the projection light. A locking mechanism is provided on the hinge structure to lock the hinge structure in place, preventing changes in the perpendicularity between the 3D modulator 1 and the projection light during normal use. This allows the 3D modulator mounting bracket to adapt to different models and shapes of projectors 5, and eliminates the need for complex bracket structures and tracks during installation. This simplifies the 3D modulator mounting bracket structure, makes installation more convenient, and greatly improves its adaptability, reducing the requirements for the installation site. After installation, the rotary motor 2 drives the 3D modulator 1 to rotate in the plane perpendicular to the projection light, achieving 2D / 3D switching.
[0029] In a preferred embodiment, the hinge structure is a ball joint, which includes a ball head 6, a ball head sleeve 7, a connecting rod 8, and a locking member. The ball head sleeve 7 surrounds the ball head 6, and the connecting rod 8 is located at the end of the ball head 6 away from the ball head sleeve 7. The ball head sleeve 7 has a through hole for the locking member to pass through. The locking member passes through the through hole and abuts against the ball head 6 to lock the ball head 6. Preferably, the ball joint is located between the connecting rod 3 and the support rod 4. The ball head sleeve 7 is connected to the support rod 4, and the connecting rod 8 is connected to the connecting rod 3. The ball joint has the characteristics of flexible and accurate control, large torsion angle, convenient installation and adjustment, and safety and reliability, making the angle adjustment of the 3D modulator 1 more convenient.
[0030] Preferably, the locking element is a locking bolt 16, and the inner wall of the corresponding through hole is provided with an internal thread that matches the locking bolt 16; of course, the locking element can also be a rod, and the end of the rod that contacts the ball head 6 is treated with anti-slip treatment. When the locking element is a rod, its fit with the through hole is an interference fit to ensure that the locking element can provide sufficient locking force to the ball head 6.
[0031] In a preferred embodiment, a first through groove 9 is provided on the connecting rod 3 along the extension direction of the connecting rod 3; furthermore, the connecting rod 8 is provided with an external thread, the connecting rod 8 passes through the first through groove 9, and is connected to the connecting rod 3 by a nut. By cooperating with the nut, the ball joint connected to the support rod 4 can be fixed at different positions of the connecting rod 3, that is, the connecting rod 3 can move up and down along the extension direction of the first through groove 9 to adjust the vertical position of the 3D modulator 1, which further improves the adaptability of the 3D modulator mounting bracket.
[0032] As a preferred approach, multiple first through slots 9 are provided. The multiple first through slots 9 effectively increase the range of movement of the 3D modulator 1 along the extension direction of the first through slot 9. More preferably, multiple first through slots 9 are spaced apart, and a portion of sheet metal is retained between adjacent first through slots 9 to ensure the overall strength of the connecting rod 3.
[0033] Furthermore, such as Figure 3 As shown, in order to increase the adjustment range of the 3D modulator 1 in the vertical direction, multiple connecting rods 3 are provided, and the first through slots 9 of two adjacent connecting rods 3 are connected together by bolts.
[0034] As a preferred embodiment, the hinge structure is a connecting block 10. The first end of the connecting block 10 is slidably connected to the connecting rod 3, and the second end of the connecting block 10 is rotatably connected to the support rod 4. The first end is provided with a sliding locking mechanism, and the second end is provided with a rotation locking mechanism. More preferably, the first end of the connecting block 10 is provided with a sliding groove 17, and the connecting rod 3 is slidably disposed in the sliding groove 17 and can slide up and down along the sliding groove 17 to adjust the vertical position of the 3D modulator 1. The second end of the connecting block 10 is provided with a rotation groove 18, and the rotation axis of the rotation groove 18 is vertically disposed. The support rod 4 is rotatably disposed in the rotation groove 18 through the rotation axis to adjust the angle of the 3D modulator 1.
[0035] More preferably, both the sliding locking mechanism and the rotating locking mechanism can be tightening bolts or snap-fit pins, etc. It is understood that: when tightening bolts are used, threaded holes are provided at the first and second ends of the connecting block 10; when snap-fit pins are used, through holes for the pin to pass through are provided at the first and second ends of the connecting block 10. Corresponding to the through holes on the connecting block, snap-fit holes for the pin to be inserted are provided on the connecting rod 3 and the support rod 4.
[0036] As a preferred method, the mounting base of the rotary motor 2 and the connecting rod 3 are rotatably connected by a hinge shaft, so that the angle of the 3D modulator 1 can be adjusted by changing the angle of the rotary motor 2, further improving the adaptability of the 3D modulator mounting bracket. The hinge shaft has a self-locking effect to fix the 3D modulator 1 at a suitable angle. More preferably, the hinge shaft is a bolt assembly. The mounting base of the rotary motor 2 is provided with a connecting lug 19 that matches the connecting rod 3. The connecting lug 19 and the connecting rod 3 are respectively provided with through holes. The bolt of the bolt assembly passes through the through holes. After adjusting the 3D modulator 1 to a suitable angle, tightening the nut of the bolt assembly can fix the angle of the 3D modulator 1.
[0037] Please continue to refer to this. Figure 1-5 In one embodiment, a second through groove 11 is provided on the support rod 4 along the extension direction of the support rod 4. A connecting bolt 14 is provided in the second through groove 11. The size of the connecting bolt 14 matches the threaded hole on the top of the projector 5. Thus, the support rod 4 is detachably installed on the top of the projector 5 through the second through groove 11. The installation position of the support rod 4 can be changed through the second through groove 11 to adjust the horizontal position of the 3D modulator 1. Furthermore, multiple second through grooves 11 are provided, and multiple second through grooves 11 are spaced apart. A portion of sheet metal is retained between adjacent second through grooves 11 to ensure the overall strength of the support rod 4.
[0038] As a preferred method, in order to further improve the strength of the connecting rod 3 and the support rod 4, flanges 12 are provided on both sides of the connecting rod 3 and the support rod 4.
[0039] As a preferred embodiment, the 3D modulator mounting bracket also includes a support column 13 and a connecting bolt 14. The support column 13 has a connecting through hole along the axial direction and is positioned between the support rod 4 and the projector 5. The connecting bolt 14 passes through the connecting through hole to install the support rod 4 into the threaded hole on the top of the projector 5. The support column 13 allows a certain distance to be maintained between the support rod 4 and the projector 5, which can prevent the support rod 4 from rubbing against the projector 5 during position adjustment and causing wear on the projector 5. At the same time, the friction surface between the support rod 4 and the support column 13 is much smaller than the friction surface when the support column 13 is in direct contact with the projector 5. In comparison, the support rod 4 experiences less frictional resistance during adjustment in this configuration, making it easier to adjust the position of the support rod 4.
[0040] Meanwhile, since the top surface of some projectors is not a standard flat surface, if the support rod 4 is directly attached to the top surface of the projector, the entire bracket will tilt in a certain direction. The setting of the support column 13 allows the support rod 4 to have a certain gap with the top surface of the projector 5, avoiding the problem of the support rod 4 and the entire 3D modulator mounting bracket tilting with the curved surface of the top of the projector.
[0041] As another feasible implementation, the 3D modulator mounting bracket also includes a sliding sleeve 15, which is bolted to the projector 5. The support rod 4 is slidably connected to the sliding sleeve 15. The sliding sleeve 15 is provided with a sliding locking mechanism for locking the support rod 4. The sliding sleeve 15 and the support rod 4 cooperate to achieve stepless adjustment of the horizontal position of the support rod 4, which is more conducive to the precise control of the horizontal position of the 3D modulator 1. The preferred sliding locking mechanism is a top bolt.
[0042] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
[0043] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
