[0002] As a large-screen display device, the ease of installation and image adjustment of laser TVs directly impacts the user experience. Currently, laser TV installation typically requires tilting and rotating the screen using casters on the bottom or side to achieve horizontal alignment and keystone correction.

[0003] However, existing casters mostly use threaded casters (2 or 4) fixed to the bottom of the main unit. The height is adjusted by rotating each caster individually, thereby controlling the pitch angle. The adjustment scheme is complicated and relies on professional personnel. Utility Model Content

[0056] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0057] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0058] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0059] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0060] Image devices such as laser TVs and projectors involve angle adjustments. For example, during installation, laser TVs require adjustments to the rotation and tilt angles to ensure geometrically correct image quality and high clarity. Similarly, projectors require adjustments to the tilt and orientation during installation to ensure the projected image is fully displayed on the screen. For ease of description, the following text will only use laser TVs as an example.

[0061] Currently, most laser TVs use casters that are threaded to the bottom of the main unit. Tilting is achieved by rotating these threads to raise or lower the casters at different positions. Specifically, there are usually two or four casters, and the adjustment logic of the casters is matched to the actual picture quality. However, if the main unit shifts due to accidental touch, cleaning, or moving and then resetting it, it becomes difficult to control which caster to adjust or how the casters should work together. This makes overall adjustment difficult, time-consuming, and laborious, and restores the original position more challenging.

[0062] To improve the ease of adjustment, related products place casters on the side of the main unit. Through gear engagement, hand power is transmitted to the casters, allowing adjustment of the threaded connection depth between the casters and the main unit, thereby adjusting the pitch and rotation angles of the main unit. However, during adjustment, the height adjustment on the left and right sides is difficult to control, meaning the pitch and rotation angles cannot be precisely controlled, making adjustment challenging. Therefore, this application provides an adjustable gimbal.

[0063] See Figure 2 , Figure 7 and Figure 13 The gimbal adjustment includes a base 10, a rotating shaft 20, a first damping element 30, a fixing plate 40, and an adjusting element 50. The rotating shaft 20 is fixedly connected to the base 10. The first damping element 30 is sleeved on the rotating shaft 20. One of the first damping element 30 and the base 10 has a spherical convex surface 31, and the other has a spherical concave surface 11. (See reference...) Figure 4 The spherical convex surface 31 fits against the spherical concave surface 11. The fixing plate 40 is used to fix the main unit 100, and the first damping member 30 is fixed to the fixing plate 40. The adjusting member 50 is threadedly connected to the rotating shaft 20 and is pressed onto the side of the first damping member 30 away from the base 10.

[0064] See Figure 1 , Figure 6 and Figure 12 The base 10 serves as a support structure, placed on a table or fixed to a wall during use. The rotating shaft 20 is fixed to the base 10 with screws or is an integral part of the base 10. In some embodiments, the bottom surface of the base 10 is flat to facilitate placement and installation. The upper surface of the base 10 is a spherical concave surface 11, and the lower surface of the first damping member 30 is a spherical convex surface 31, which fits against the spherical concave surface 11. The rotating shaft 20 is fixed at the lowest point of the spherical concave surface 11, and the first damping member 30 is sleeved on the rotating shaft 20. In some embodiments, the bottom surface of the base 10 is flat, the upper surface of the base 10 is a spherical convex surface 31, and the lower surface of the first damping member 30 is a spherical concave surface 11, which fits against the spherical convex surface 31.

[0065] It should be noted that, for reference Figure 2 The first damping element 30 is provided with a first shaft hole 32, the diameter of which is larger than the shaft diameter of the rotating shaft 20. The rotating shaft 20 passes through the first shaft hole 32. When adjusting the pitch angle of the gimbal, the first shaft hole 32, which is larger than the shaft diameter of the rotating shaft 20, provides space for the relative sliding of the spherical concave surface 11 and the spherical convex surface 31.

[0066] The first damping element 30 is fixedly connected to the fixing plate 40 by a first fastener 91. Specifically, the fixing plate 40 is provided with a plurality of first mounting holes 41, and the first fastener 91 passes through the first mounting holes 41 and is connected to the first damping element 30. Optionally, the first fastener 91 is a rivet or a screw. See reference. Figure 2 , Figure 7 and Figure 13 The fixing plate 40 has six first mounting holes 41, and correspondingly, six first fasteners 91 are provided. The six first mounting holes 41 are evenly distributed circumferentially around the axis of the rotation shaft 20. In some optional embodiments, the first damping member 30 has a flange that fits against the fixing plate 40, and the first fasteners 91 pass through the first mounting holes 41 and are connected to the flange.

[0067] The fixing plate 40 is a plate body, with both its upper and lower surfaces being flat. The fixing plate 40 has a second mounting hole 42, through which a second fastener 92 passes and connects to the main unit 100. (See reference...) Figure 2 The fixing plate 40 is provided with four second mounting holes 42, which are arranged at the corners of the fixing plate 40.

[0068] like Figure 3 , Figure 8 , Figure 9 , Figure 14 and Figure 15 As shown, the rotating shaft 20 has a threaded hole, and the adjusting member 50 is inserted into the threaded hole, so that the rotating shaft 20 and the adjusting member 50 are threadedly engaged. The adjusting member 50 includes a rod body and a cap body fixed to one end of the rod body, and the rod body has a threaded section. Optionally, the entire rod body is threaded, and the adjusting member 50 is an adjusting bolt. Alternatively, only part of the rod body is threaded, and the other part is a smooth rod. After the adjusting member 50 and the rotating shaft 20 are threaded together, refer to [reference needed]. Figure 4 The first damping element 30 is clamped between the base 10 and the nut of the adjusting element 50. The depth to which the adjusting element 50 is screwed into the adjusting threaded hole will change the damping force between the spherical convex surface 31 and the spherical concave surface 11.

[0069] Understandably, the top surface of the adjusting element 50 is lower than the upper surface of the fixed plate 40. For example... Figure 2 and Figure 3 As shown, the fixed plate 40 has a through hole 43, through which the adjusting member 50 passes and is connected to the rotating shaft 20. The diameter of the through hole 43 is larger than the outer diameter of the cap of the adjusting member 50, making it convenient to rotate the adjusting member 50.

[0070] When adjusting the friction between the spherical convex surface 31 and the spherical concave surface 11, loosening the adjusting component 50 reduces the friction between them. Tightening the adjusting component 50 increases the friction. The friction between the spherical convex surface 31 and the spherical concave surface 11 can be adjusted by changing the thread depth between the adjusting component 50 and the rotating shaft 20. During the gimbal production process, the friction between the spherical concave surface 11 and the spherical convex surface 31 is adjusted to the correct position using the adjusting component 50. Specifically, the friction between the spherical concave surface 11 and the spherical convex surface 31 satisfies the needs of rotation and pitch angle adjustments, and also provides a certain locking capability after the rotation and pitch angles are adjusted to the correct position, stabilizing the main unit 100 in the current position. In use, the main unit 100 is fixed to the fixing plate 40, and then the position of the main unit 100 is adjusted by the friction, i.e., the damping force, between the spherical concave surface 11 and the spherical convex surface 31. (See reference...) Figure 5 The fixed plate 40 is tilted to an inclined plane. After the position is adjusted, it is fixed in the current position by the friction between the spherical concave surface 11 and the spherical convex surface 31.

[0071] The adjustable gimbal provided in this application can adjust the friction force, i.e., the damping force, between the spherical concave surface 11 and the spherical convex surface 31 by adjusting the threaded connection depth between the adjusting component 50 and the rotating shaft 20. When adjusting the position of the main unit 100, the user can directly apply force to the fixed plate 40, which is convenient and easy to operate.

[0072] In some alternative embodiments, see Figure 2 and Figure 4 The gimbal adjustment also includes a butterfly-shaped shim 61, which is sleeved on the adjustment member 50 and sandwiched between the first damping member 30 and the cap of the adjustment member 50. And / or, see [reference needed]. Figure 2 and Figure 4 The gimbal adjustment also includes a damping pad 62, which is sleeved on the adjustment member 50 and sandwiched between the first damping member 30 and the cap of the adjustment member 50.

[0073] The upper surface of the butterfly-shaped shim 61 contacts the cap of the adjusting component 50, and the lower surface of the butterfly-shaped shim 61 contacts the upper surface of the first damping component 30. When the adjusting component 50 is turned to a certain torque, the butterfly-shaped shim 61 is compressed, and the longitudinal height of the butterfly-shaped shim 61 decreases, generating a larger elastic force. This causes a certain frictional force (i.e., damping force) between the spherical concave surface 11 and the spherical convex surface 31, thereby providing appropriate damping force when adjusting the gimbal for pitch and rotation. This allows for easy adjustment of the position of the main unit 100 and also helps the main unit 100 maintain the current adjustment position for a short period of time.

[0074] Damping shim 62 is a common shim structure used to prevent adjusting bolts from loosening and to absorb vibration and disperse stress; no specific details are provided.

[0075] It should be noted that in some embodiments, the adjustment gimbal only has a butterfly-shaped pad 61, the upper surface of which directly contacts the cap of the adjustment member 50, and the lower surface of which directly contacts the upper surface of the first damping member 30. In some embodiments, the adjustment gimbal only has a damping pad 62, the upper surface of which directly contacts the cap of the adjustment member 50, and the lower surface of which directly contacts the upper surface of the first damping member 30. The damping pad 62 is used to prevent loosening. In some embodiments, the adjustment gimbal includes a butterfly-shaped pad 61 and a damping pad 62, with the butterfly-shaped pad 61 positioned above the damping pad 62. Specifically, the upper surface of the butterfly-shaped pad 61 contacts the cap of the adjustment member 50, the lower surface of the butterfly-shaped pad 61 contacts the upper surface of the damping pad 62, and the lower surface of the damping pad 62 contacts the upper surface of the first damping member 30.

[0076] When the gimbal adjustment includes a butterfly shim 61, the butterfly shim 61 is sandwiched between the cap of the adjustment member 50 and the upper surface of the first damping member 30. The elasticity provided by the butterfly shim 61 helps to adjust the magnitude of the damping force and prevents the adjustment member 50 from becoming loose.

[0077] Understandably, the gimbal adjustment can also be done without the butterfly shim 61, and the appropriate friction between the spherical convex surface 31 and the spherical concave surface 11 can be achieved directly by using the adjustment component 50.

[0078] In some specific embodiments of this application, see [reference]. Figure 2 , Figure 7 and Figure 13 The base 10 includes a gimbal base 12, a second damping element 13, and a third damping element 14. A rotating shaft 20 is fixed to the gimbal base 12, and the second damping element 13 is sleeved on the rotating shaft 20. The third damping element 14 is fixedly connected to the gimbal base 12. The third damping element 14 has a through hole 141, and the second damping element 13 is inserted into the through hole 141. One of the sides of the second damping element 13 facing away from the gimbal base 12 and the side of the first damping element 30 facing the gimbal base 12 has a spherical concave surface 11, and the other has a spherical convex surface 31.

[0079] The rotating shaft 20 is fixed to the gimbal base 12 by screws or is an integral part of the gimbal base 12. In some optional embodiments, the rotating shaft 20 and the gimbal base 12 are an integral part. Specifically, the rotating shaft 20 protrudes from one side of the gimbal base 12. In still other optional embodiments, the rotating shaft 20 is fixed to the gimbal base 12 by fasteners such as rivets or screws. Optionally, the gimbal base 12 has a stepped hole at its center, and the rotating shaft 20 is inserted into the stepped hole. The rotating shaft 20 has a stepped surface, and the stepped surface of the stepped hole abuts against the stepped surface. Thus, the stepped hole provides positioning for the installation of the rotating shaft 20.

[0080] Optionally, the third damping element 14 is fixed to the gimbal base 12 by a third fastener 93. The third fastener 93 is a screw or a rivet. See reference. Figure 2 , Figure 7 and Figure 13 The gimbal base 12 has a third mounting hole 121, through which a third fastener 93 passes and connects to a third damping component 14. Multiple third mounting holes 121 are provided. (See reference...) Figure 2 There are four third mounting holes 121, and correspondingly, four third fasteners 93 are provided, which are evenly distributed circumferentially around the axis of the rotation shaft 20. (See reference...) Figure 7 and Figure 13 There are two third mounting holes 121, and correspondingly, there are two second fasteners 92. Of course, the number of third mounting holes 121 can also be three, five, six, etc.

[0081] Optionally, the gimbal base 12 is a circular plate. Alternatively, the gimbal base 12 can also be square, polygonal, etc. After the third damping member 14 is fixed to the gimbal base 12, one end of the through hole 141 is blocked by the gimbal base 12, thus forming a receiving groove. The second damping member 13 is inserted into the receiving groove, and the circumferential outer wall of the second damping member 13 is in contact with the hole wall of the through hole 141. The lower surface of the second damping member 13 is flat, and the upper surface is a spherical convex surface 31 or a spherical concave surface 11. The flat side of the second damping member 13 is in contact with the upper surface of the gimbal base 12.

[0082] It should be noted that, for reference Figure 2 , Figure 7 and Figure 13 The second damping element 13 has a second shaft hole 132, through which the rotating shaft 20 passes. The diameter of the second shaft hole 132 is smaller than that of the first shaft hole 32, but both are larger than the shaft diameter of the rotating shaft 20. When adjusting the friction between the spherical convex surface 31 and the spherical concave surface 11, the damping force between the second damping element 13 and the third damping element 14 will also change. Specifically, when the adjusting element 50 is tightened, the damping force between the spherical concave surface 11 and the spherical convex surface 31 increases, and the second damping element 13 is pressed down, increasing the damping force between the second damping element 13 and the third damping element 14. When the adjusting element 50 is loosened, the damping force between the spherical concave surface 11 and the spherical convex surface 31 decreases, and the degree of pressing down of the second damping element 13 decreases, decreasing the damping force between the second damping element 13 and the third damping element 14. Therefore, by adjusting the adjusting member 50, the damping force between the first damping member 30 and the second damping member 13, as well as the damping force between the second damping member 13 and the third damping member 14, can be adjusted.

[0083] The adjustable gimbal provided in this application embodiment includes a base 10 comprising a gimbal base 12, a second damping element 13, and a third damping element 14, which simplifies the structure of each component and facilitates processing and manufacturing.

[0084] In some alternative embodiments, see Figure 2 , Figure 7 and Figure 13 The through hole 141 is circular, and the outer wall of the second damping member 13 is columnar. When the second damping member 13 is inserted into the through hole 141, there is surface contact between the second damping member 13 and the first damping member 30. In some optional embodiments, the through hole 141 is tapered, and the side of the second damping member 13 facing away from the first damping member 30 has a tapered surface adapted to the tapered hole. The larger end of the tapered hole faces upward, facilitating the insertion of the second damping member 13 into the through hole 141. When the second damping member 13 is inserted into the through hole 141, there is surface contact between the second damping member 13 and the first damping member 30. In some optional embodiments, the through hole 141 is tapered, and the side of the second damping member 13 facing away from the first damping member 30 is columnar. When the second damping member 13 is inserted into the through hole 141, there is line contact between the second damping member 13 and the first damping member 30. Compared to line contact, surface contact can increase the contact area between the third damping element 14 and the second damping element 13, thereby increasing damping and improving the stability of the gimbal.

[0085] In some specific embodiments, see Figure 6 and Figure 12 The pan-tilt head adjustment also includes a locking handle 70. For example... Figure 7 and Figure 13 As shown, the wall of the through hole 141 has an opening 142, and the locking handle 70 is rotatably mounted on the third damping member 14. When the locking handle 70 is rotated to the locked position, the opening 142 has a first opening degree; when the locking handle 70 is rotated to the non-locked position, the opening 142 has a second opening degree, and the first opening degree is smaller than the second opening degree.

[0086] like Figure 7 and Figure 13As shown, the third damping element 14 is C-shaped and has an opening 142. Rotating the locking handle 70 adjusts the opening of the opening 142. When the locking handle 70 is rotated to the locked position, the opening of the opening 142 is smaller than in the unlocked position, causing the third damping element 14 and the second damping element 13 to grip more tightly, resulting in greater friction between them. Simultaneously, under the gripping force of the third damping element 14, the upper surface of the second damping element 13 presses more firmly against the lower surface of the first damping element 30, meaning greater friction between the spherical concave surface 11 and the spherical convex surface 31, thereby increasing the damping between the second damping element 13 and the first damping element 30. When the locking handle 70 is rotated to the unlocked position, the opening of the opening 142 is larger, and the damping force between the third damping element 14 and the second damping element 13 is controlled by the adjusting element 50 to prevent the opening 142 from gripping too tightly and affecting the adjustment of the gimbal position.

[0087] When in use, after the position of the main unit 100 is adjusted, manually move the locking handle 70 to switch the locking handle 70 to the locked state. At this time, the pan-tilt head will provide a greater damping force than when adjusting the position, so that the pan-tilt head can be more stably kept in the current position, thereby locking the position of the main unit 100. This can prevent the main unit 100 from shifting due to accidental touching, cleaning, moving the main unit 100 away and then resetting it.

[0088] The adjustable gimbal provided in this embodiment has an opening 142 in the through hole 141. When in use, after the position of the main unit 100 is adjusted, the locking handle 70 is moved by hand to the locking position to lock the position after final adjustment. In addition to stabilizing the position of the gimbal by the damping force between the damping components, the position of the gimbal can also be stabilized by locking the opening 142 of the locking handle 70, which more effectively prevents the main unit 100 from shifting due to external force.

[0089] In some specific embodiments of this application, the outer wall of the locking handle 70 near the third damping member 14 is cam-shaped.

[0090] Specifically, the third damping element 14 has two lugs 143, which are located on opposite sides of the opening 142. A locking pin 71 passes through the two lugs 143, and a fixing pin 72 is inserted into the tail of the locking pin 71. The locking handle 70 is mounted on the locking pin 71. The extension direction of the fixing pin 72 is perpendicular to the extension direction of the locking pin 71. As the locking handle 70 rotates, different positions of the outer wall of the locking handle 70 contact the lugs 143. When the locking handle 70 is in the locked position, the highest point of the locking handle 70 abuts against the lugs 143; when the locking handle 70 is in the locked position, the non-highest points of the locking handle 70 abut against the lugs 143 or have a gap with the lugs 143.

[0091] The end of the locking pin 71 is U-shaped, and the tail of the locking pin 71 is accommodated in the U-shaped groove.

[0092] See Figure 10 When the locking handle 70 is rotated to the locked position, the highest point of the locking handle 70 abuts against the lug 143, pulling the locking pin 71, causing the two lugs 143 to move closer to each other, and the opening 142 to contract. That is, the opening 142 of the third damping member 14 changes from the second opening to the first opening, thereby pressing the second damping member 13 to contract and move upward synchronously, increasing the friction between the mating surfaces of the second damping member 13 and the first damping member 30, and further locking the position after the final adjustment.

[0093] See Figure 11 When the locking handle 70 is rotated to the non-locking position, the highest point of the cam moves away from the lug 143, thereby reducing the constraint force between the two lugs 143. The opening 142 opens, that is, the opening 142 increases from the first opening degree to the second opening degree. The gimbal only has the damping force after the adjusting part 50 is turned. At this time, the pitch and rotation angles can be freely adjusted, and the gimbal position can be initially fixed by the damping force after adjustment.

[0094] In some alternative embodiments, see Figure 7 and Figure 13 The gimbal base 12 has a clearance hole 122, and a portion of the locking handle 70 is housed within the clearance hole 122.

[0095] The clearance hole 122 can be either a through hole 141 or a blind hole. (See reference...) Figure 8 and Figure 14 There is a gap between the fixing plate 40 and the gimbal base 12. The end of the locking handle 70 has a certain thickness. In order to avoid interference between the locking handle 70 and the fixing plate 40, a clearance hole 122 is provided on the gimbal base 12. The bottom of the locking handle 70 is accommodated in the clearance hole 122, which makes it convenient for the user to operate the locking handle 70.

[0096] In some specific embodiments of this application, the gimbal base 12 is recessed. See also... Figure 13 , Figure 14 and Figure 15 The gimbal base 12 has a recessed center and a higher outer edge than the center. The outer edge covers the structural components between the gimbal base 12 and the fixing plate 40, improving the aesthetic appearance.

[0097] In some embodiments, the first damping member 30 is a member of uniform thickness. The adjusting gimbal also includes a damping adjustment member 80, which is fixedly connected to the first damping member 30. The damping adjustment member 80 has a planar area on the side facing the fixed plate 40, through which the rotation shaft 20 passes.

[0098] It should be noted that there is a gap between the top surface of the damping adjustment component 80 and the bottom surface of the fixing plate 40, which provides space for the adjustment bolt to be installed.

[0099] Specifically, when the side of the first damping member 30 facing the second damping member 13 is a spherical convex surface 31, and the side of the first damping member 30 facing the fixed plate 40 is a concave surface, if the adjusting member 50 is directly installed in the concave surface, the adjusting member 50 and the first damping member 30 will have line contact, resulting in poor force transmission. Therefore, a damping adjustment member 80 is added inside the first damping member 30. The adjusting member 50, the butterfly-shaped washer 61, and the damping washer 62 are positioned corresponding to the planar area to facilitate force transmission. Optionally, the damping adjustment member 80 has a structure with one side flat and the other side convex, with the convex side of the damping adjustment member 80 fitting against the concave surface of the first damping member 30. When the side of the first damping member 30 facing the second damping member 13 is a spherical concave surface 11, and the side of the first damping member 30 facing the fixed plate 40 is a convex surface. At this time, the damping adjustment component 80 has a structure with one side flat and the other side concave. The flat side of the damping adjustment component 80 faces the fixing plate 40, and the concave side is in contact with the first damping component 30.

[0100] In some embodiments, the first damping member 30 is a non-uniform thickness member. Specifically, the first damping member 30 has a groove on the side facing the fixing plate 40, and the bottom of the groove is a flat surface, which provides sinking space for the installation of the adjusting bolt.

[0101] See Figure 16 and Figure 17 This application also provides a display device component, which includes a host 100 and an adjustment pan-tilt unit as described above, wherein the host 100 is fixedly connected to the fixing plate 40.

[0102] The host device 100 can be a laser host device 100 or a projector, or other electronic device. Taking a laser TV as an example, the host device 100 adjusts the tilt and rotation angles by adjusting the pan and tilt mechanism. Figure 18 As shown, ensure that the image is displayed clearly.

[0103] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
