Description

Technical Field

[0001] This application relates to the field of laser TV technology, and in particular to control pan-tilt units and laser TVs. Background Technology

[0002] Regarding existing laser TVs, due to the actual usage scenarios of users and the levelness of the wall or mounting surface / desktop, the image projected by the laser host may not completely fill the screen or the image on the screen may not be a regular rectangle, resulting in an irregular shape for the entire image.

[0003] To address this issue, most existing laser projectors require adjusting various casters at the bottom of the projector during installation or use to adjust the image. The principle behind adjusting these casters is to directly change the height difference of the four sides and four corners of the projected image by adjusting the overall height difference of the laser projector. Combined with manually rotating the laser projector, this two-step process alters the shape of the image or the position of its four sides / corners, thus creating a regular rectangular image.

[0004] However, the above adjustments usually require manual adjustments by installers or users, making the entire debugging process difficult and failing to provide users with a good user experience. Utility Model Content

[0005] Therefore, it is necessary to provide a controllable PTZ and laser TV to address the aforementioned technical issues.

[0006] This application provides a control gimbal, the control gimbal comprising:

[0007] A telescopic mechanism includes a fixed body, a moving body, and a telescopic drive assembly. The moving body is movably mounted on the fixed body, and the telescopic drive assembly is mounted on the fixed body. The telescopic drive assembly is drivenly connected to the moving body and is used to drive the moving body to reciprocate relative to the fixed body along a telescopic trajectory.

[0008] A rotating mechanism is directly or indirectly assembled to the moving body; the rotating mechanism includes a rotating motor and a rotating worm gear, the rotating worm gear includes a rotating worm component and a rotating worm wheel component, the rotating motor is drivenly connected to the rotating worm component, and the rotating worm component is drivenly engaged with the rotating worm wheel component to drive the rotating worm wheel component to rotate along a fixed axis of rotation;

[0009] A pitch mechanism, which is directly or indirectly mounted on the rotating worm gear, includes at least two lifting components, and several of the lifting components are configured to directly or indirectly connect to the target body for adjusting the pitch angle of the plane in which the target body is located.

[0010] In the above embodiments, the laser TV of this application, by integrating a control pan-tilt unit, can solve the problem of irregular image projection caused by the levelness of the wall or mounting surface during the installation and use of existing laser TVs. Unlike traditional laser TVs that require manual adjustment of casters to adjust the image, the laser TV of this application can achieve automatic and precise adjustment through the control pan-tilt unit.

[0011] When the laser TV is working, the telescopic mechanism of the control pan-tilt unit can adjust the front and back position of the laser TV to achieve fine-tuning of the projection distance; the rotation mechanism can drive the laser TV to rotate around the rotation axis to achieve horizontal angle adjustment; the pitch mechanism changes the projection angle of the laser TV by controlling the height of the lifting components to achieve precise pitch adjustment.

[0012] This design allows the laser TV to automatically adjust the projection angle and position according to the actual installation environment, ensuring that the projected image appears as a regular rectangle on the screen, eliminating the need for manual adjustment of the casters and greatly improving the user experience. At the same time, the precise control mechanism of the pan-tilt unit ensures the accuracy and stability of the laser TV's image adjustment, avoiding the inaccuracies that can occur with traditional manual adjustments.

[0013] In one embodiment, the fixed body and the moving body are configured as a shell structure; and / or,

[0014] The telescopic drive assembly includes a telescopic motor, a telescopic lead screw, and a telescopic slide rail. The moving body is movably mounted to the fixed body via the telescopic slide rail. The telescopic motor is mounted to the fixed body and is driven by the moving body via the telescopic lead screw; and / or...

[0015] The fixed body has a first space with an opening inside, and the moving body has a second space with an opening inside. The first space and the second space are combined between the fixed body and the moving body to form a storage space, and the telescopic drive assembly is assembled in the storage space.

[0016] In the above embodiments, the fixed body and the moving body can be configured as a shell structure. The fixed body has a first space with an opening inside, and the moving body has a second space with an opening inside. The first and second spaces, combined between the fixed body and the moving body, form a storage space, in which the telescopic drive assembly is assembled. The storage space can not only be used to install the telescopic drive assembly but also to house other functional components such as circuit boards and batteries, achieving a compact and integrated structure. The inner wall of the storage space can be designed with a heat dissipation structure to effectively reduce the heat generated by the internal components during operation and extend the equipment's service life.

[0017] In one embodiment, the telescopic slide includes a telescopic track component and a telescopic bearing component, which are respectively assembled to the fixed body and the moving body; wherein, the telescopic track component has a telescopic track groove, and the telescopic track groove has a first track auxiliary groove and a second track auxiliary groove with opposite and symmetrical openings; the number of telescopic bearing components is configured to be several, with several telescopic bearing components rollingly assembled in the telescopic track groove of the telescopic track component, some of the telescopic bearing components rollingly assembled in the first track auxiliary groove and tangent to the bottom wall of the first track auxiliary groove, and another portion of the telescopic bearing components rollingly assembled in the second track auxiliary groove and tangent to the bottom wall of the second track auxiliary groove; and / or,

[0018] The telescopic mechanism includes a floating component, and the telescopic lead screw is driven to the moving body through the floating component.

[0019] In the above embodiments, based on the assembly design of the two telescopic bearing components with the first track groove and the second track groove respectively, the load-bearing function and the guiding function can be realized.

[0020] In one embodiment, a portion of the telescopic bearing located in the first track groove is in clearance fit with the groove sidewall of the first track groove, and a portion of the telescopic bearing located in the second track groove is in clearance fit with the groove sidewall of the second track groove.

[0021] In the above embodiments, the clearance fit can constrain the telescopic bearing to move along the telescopic track groove, the first track auxiliary groove and the second track auxiliary groove, and also prevent lateral movement when under load.

[0022] In one embodiment, the rotating mechanism includes a rotating base, which is mounted to the moving body via a rotating substrate, and the rotating worm gear is rotatably mounted on the rotating base along a fixed axis; a limiting component is provided between the rotating worm gear and the rotating base to limit the rotating worm gear to rotate only along the rotation axis relative to the fixed axis of the rotating base, and to prohibit the rotating worm gear from moving radially and axially along the rotation axis.

[0023] In the above embodiments, the limiting component effectively prevents radial and axial movement of the rotating worm gear during operation, ensuring the motion accuracy of the rotating mechanism.

[0024] In one embodiment, the limiting assembly includes a first limiting component and a second limiting component. The rotating base has a seat cavity inside, and the first and second limiting components are assembled in the seat cavity. The first limiting component is radially limited between the rotating base and the rotating worm gear component, thereby restricting the radial movement of the rotating worm gear component relative to the rotating base. The second limiting component is axially limited between the rotating base and the rotating worm gear component, thereby restricting the axial movement of the rotating worm gear component relative to the rotating base; and / or,

[0025] The rotating mechanism includes a transmission assembly, and the rotating motor is connected to the rotating worm gear through the transmission assembly.

[0026] In the above embodiments, due to the limiting effect of the first limiting component and the second limiting component, the rotating worm gear component can only rotate within the rotating base and will not undergo radial or axial displacement, thereby ensuring the stability and accuracy of the rotating mechanism.

[0027] In one embodiment, the first limiting component is configured as a first annular limiting bearing, and the second limiting component is configured as a second annular limiting bearing. The interior of the rotating base has at least a first limiting step and a second limiting step. The first limiting bearing is mounted on the first limiting step, and the inner wall of the first limiting bearing radially limits and abuts against the rotating worm gear component. The outer wall of the first limiting bearing radially limits and abuts against the rotating base, thereby preventing the rotating worm gear component from moving radially relative to the rotating base. The second limiting bearing is mounted on the second limiting step, and the inner wall of the second limiting bearing is radially rotatably mounted against the rotating worm gear component. The outer wall of the second limiting bearing radially rotatably mounts against the rotating base, thereby preventing the rotating worm gear component from moving axially relative to the rotating base.

[0028] In one embodiment, the pitch mechanism includes three lifting components configured to directly or indirectly connect to three different positions of the target body for adjusting the pitch angle of the plane in which the target body is located; or,

[0029] The pitch mechanism includes two lifting components and one omnidirectional rotating component. The two lifting components and one omnidirectional rotating component are configured to directly or indirectly connect to three different positions of the target body for adjusting the pitch angle of the plane in which the target body is located.

[0030] In the above embodiments, when the pitch mechanism performs pitch adjustment, the core is to utilize the geometric characteristics of "three-point plane" and the optical principle of "projection angle correction". At the same time, it can be combined with real-time feedback control to accurately adjust the body attitude to eliminate image distortion.

[0031] In one embodiment, the lifting assembly includes a pitch base, a pitch motor, and a pitch worm gear. The pitch base is mounted on the rotating worm gear via a pitch base plate. The pitch worm gear includes a pitch worm gear component and a pitch worm component. The pitch motor is drivenly connected to the pitch worm gear component, and the pitch worm gear component and the pitch worm component are drivenly engaged to drive the pitch worm component to reciprocate along the lifting trajectory, directly or indirectly adjusting the linear lifting of a position of the target body.

[0032] The lifting assembly further includes a limit detection assembly, which includes a detection base, a pitch screw, a gear set, and a sensor. The pitch screw includes a pitch rod and a pitch nut. The pitch rod is rotatably mounted on the detection base and is connected to the pitch worm gear via the gear set. The detection base has a detection space. The pitch nut is movably mounted on the pitch screw and located in the detection space. The sensor is disposed on the pitch nut and is used to move synchronously with the pitch nut in the detection space.

[0033] In this embodiment, the design of the limit detection component enables the lifting component to precisely control the lifting height of the target object, preventing overtravel and avoiding mechanical damage. Simultaneously, through real-time feedback from the sensors, the system can achieve closed-loop control, improving positioning accuracy and motion stability.

[0067] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0068] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as a limitation of this application.

[0069] Furthermore, where the terms "first" and "second" appear, these terms are 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0070] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0071] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0072] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0073] See Figures 1 to 16 As shown, this application provides a laser TV, which includes a control pan-tilt unit for controlling projection devices such as a laser host 100. Figure 19 and Figure 20 As shown, the laser host 100 is mounted on a control pan-tilt unit. This control pan-tilt unit integrates a three-degree-of-freedom adjustment mechanism for extension, rotation, and height pitch, thereby flexibly controlling the orientation and position of the laser host 100 in three-dimensional space. Moreover, the entire process can be automated and electronically controlled, simulating and completely replacing the manual adjustment of the laser host 100's front-back, left-right, height difference, and angle. This achieves fully automatic control, reduces installation time, and simplifies the user experience. The projected image can be adjusted automatically or remotely, achieving the effect of "one-click adjustment" or "fully automatic fine adjustment," effectively solving the problem of irregular projected images.

[0074] Therefore, the laser TV with the aforementioned control PTZ provided in this application can solve user operation pain points through fully automatic mode, and can also achieve visual adjustment of the screen through manual control of the remote control, retaining flexibility, and ultimately achieving a "precise, efficient, and intelligent" screen adjustment experience. It can achieve "intelligent correction" through multi-dimensional collaborative operation. Compared with single-dimensional adjustment, this collaborative mechanism of "extension + rotation + tilt" can cope with more complex usage scenarios (such as the laser host 100 being accidentally bumped and causing multi-angle displacement, uneven screen installation, etc.). Through the processor's overall calculation and the precise cooperation of each module, the "cross-interference" of mechanical actions is transformed into "complementary correction", ultimately achieving fast and accurate screen adaptation. This reflects the core logic of "multi-variable collaborative optimization" in automatic control, and greatly improves the ease of use and technological feel of the laser host 100.

[0075] Regarding the aforementioned control gimbal, please refer to... Figures 1 to 18 As shown, the control gimbal may include at least a telescopic mechanism 1000, a rotation mechanism 2000, and a pitch mechanism 3000. (See reference...) Figures 1 to 8 As shown, the telescopic mechanism 1000 has a telescopic function, which can control the reciprocating movement of the laser host 100 along a preset telescopic trajectory. Specifically, it mainly moves the laser host 100 along the front-back and left-right directions to correct overall image offset. For example, see... Figure 17 As shown, positional offset is divided into front and back (affecting screen size) and left and right (affecting horizontal position).

[0076] See Figures 1 to 3 As shown, in one embodiment, the telescopic mechanism 1000 may include a fixed body 1100, a moving body 1200, and a telescopic drive assembly 1300. The moving body 1200 is movably mounted on the fixed body 1100, and the telescopic drive assembly 1300 is mounted on the fixed body 1100. The telescopic drive assembly 1300 is drivenly connected to the moving body 1200 and is used to drive the moving body 1200 to reciprocate relative to the fixed body 1100 along the telescopic trajectory.

[0077] Therefore, when moving back and forth along the telescopic trajectory, the distance between the laser host 100 and the screen can be detected by the laser rangefinder sensor according to the projection ratio (e.g., a 100-inch screen requires the host to be 2.5m away from the screen), and adjusted to the standard value, thus solving the problem of the screen being too large or too small. Similarly, the horizontal position can be adjusted by moving left and right along the telescopic trajectory.

[0078] See Figures 9 to 13 As shown, the rotating mechanism 2000 has a rotation function, capable of controlling the laser host 100 to rotate on a preset rotation axis, thereby rotating left and right. The rotating mechanism 2000 can be directly or indirectly mounted on the moving body 1200. In one embodiment, see [reference needed]. Figures 9 to 11 As shown, the rotating mechanism 2000 includes a rotating motor 2100 and a rotating worm gear. The rotating worm gear includes a rotating worm component 2200 and a rotating worm wheel component 2300. The rotating motor 2100 is driven and connected to the rotating worm component 2200, and the rotating worm component 2200 is driven and engaged with the rotating worm wheel component 2300 to drive the rotating worm wheel component 2300 to rotate along the rotation axis.

[0079] See Figure 18 As shown, for example, rotating the laser host 100 around a rotation axis (such as the Z-axis) can be used to solve the problem of screen rotation tilt. The rotation angle of the projected image is consistent with the rotation angle of the laser host 100 (because the projection direction is fixed), therefore: if the image rotates clockwise by θ°, the host needs to rotate counterclockwise by θ°. The rotation mechanism 2000 can be adjusted with a precision of ±0.1° via a stepper motor to ensure that the edge of the image is parallel to the edge of the screen.

[0080] The rotary motor 2100 can be a high-precision stepper motor or servo motor, offering high positioning accuracy and stability. The output shaft of the rotary motor 2100 can be connected to the rotary worm gear 2200 via a coupling or gear transmission, transmitting the motor's rotational power to the rotary worm gear 2200. The rotary worm gear 2200 is made of cemented carbide, possessing high hardness and wear resistance. Both ends of the rotary worm gear 2200 can be optionally supported on the bracket of the rotating mechanism 2000 via bearings, ensuring stable rotation. The helical teeth of the rotary worm gear 2200 match the tooth profile of the rotary worm wheel 2300, achieving efficient and smooth power transmission.

[0081] The rotating worm gear component 2300 can also be made of high-strength alloy material, possessing sufficient strength and rigidity. Alternatively, the rotating worm gear component 2300 can be supported on the bracket of the rotating mechanism 2000 via bearings, enabling it to rotate along a fixed axis. The center of the rotating worm gear component 2300 may have a connecting structure for mounting the pitch mechanism 3000, allowing the pitch mechanism 3000 to be directly or indirectly mounted on the rotating worm gear component 2300.

[0082] After the rotary motor 2100 starts, it drives the rotating worm gear 2200 to rotate via a coupling or gear transmission. When the rotating worm gear 2200 rotates, it meshes with the rotating worm wheel 2300, driving the worm wheel 2300 to rotate along the rotation axis. The rotating worm wheel 2300 drives the pitch mechanism 3000 mounted on it to rotate together, thus realizing the rotation function of the gimbal structure. The rotating worm gear transmission has a self-locking property, which can maintain the rotational position unchanged when no power is applied, improving the stability and safety of the gimbal structure.

[0083] See Figures 14 to 16As shown, the pitch mechanism 3000 has a height pitch control function. The pitch mechanism 3000 can be directly or indirectly mounted on the rotating worm gear component 2300. The pitch mechanism 3000 includes at least two lifting components 3100. Several lifting components 3100 are configured to directly or indirectly connect to the target body for adjusting the pitch angle of the plane where the target body is located. The lifting components 3100 can be selected from electric push rods, hydraulic cylinders, or pneumatic cylinders with linear motion functions, capable of generating linear motion to transmit this linear motion to the target body, thereby adjusting the target body's pitch angle.

[0084] When the pitch mechanism 3000 performs pitch adjustment, the core is to utilize the geometric characteristics of "three-point plane fixation" and the optical principle of "projection angle correction". At the same time, it can be combined with real-time feedback control to precisely adjust the body attitude to eliminate image distortion.

[0085] For example, in one embodiment, the pitch mechanism 3000 may include three lifting components 3100 configured to directly or indirectly connect three different positions of the target body for adjusting the pitch angle of the plane on which the target body is located. Alternatively, the pitch mechanism 3000 may include two lifting components 3100 and a universal joint component configured to directly or indirectly connect three different positions of the target body for adjusting the pitch angle of the plane on which the target body is located.

[0086] In one embodiment, when the pitch mechanism 3000 includes three lifting components 3100, the three lifting components 3100 can be arranged in a triangle, providing stable support and precise pitch angle control. The three lifting components 3100 are fixedly mounted on the rotating worm gear component 2300 and connected to the target body. By controlling the extension and retraction lengths of the three lifting components 3100, the pitch angle of the target body in different directions can be adjusted.

[0087] Therefore, the telescopic mechanism 1000 can first adjust the position of the moving body 1200 relative to the fixed body 1100 to achieve the telescopic function of the gimbal structure; then, the rotating mechanism 2000 drives the rotating worm gear 2300 to rotate along the rotation axis, causing the pitch mechanism 3000 and the target body to rotate together, thus achieving the rotation function of the gimbal structure; finally, the pitch angle of the plane where the target body is located can be adjusted by several lifting components 3100 in the pitch mechanism 3000, thus achieving the pitch function of the gimbal structure. Through the combination of telescopic, rotating, and pitching movements, the gimbal structure can achieve precise positioning and attitude adjustment of the target body in space.

[0088] See Figure 1 and Figure 2As shown, in one embodiment, when the pitch mechanism 3000 includes two lifting components 3100 and a universal rotating component, the two lifting components 3100 and the universal rotating component are configured to directly or indirectly connect three different positions of the target body for adjusting the pitch angle of the plane where the target body is located.

[0089] The two lifting components 3100 can be respectively installed at two different positions on the bottom of the target body, for example, at diagonal positions on the bottom of the target body. The universal joint can be installed at a third position on the bottom of the target body, which is not collinear with the positions of the two lifting components 3100, forming a triangular support structure. The universal joint may include a universal joint and a support base. The universal joint has two mutually perpendicular rotation axes, allowing the target body to rotate in multiple directions at this connection point. The support base is fixed to the bottom base to support the universal joint and maintain its stability.

[0090] When the two lifting components 3100 simultaneously raise or lower the target body to the same height, the target body will perform a pure pitch motion. When the two lifting components 3100 change at different speeds or different heights, the target body will simultaneously produce pitch and roll motions. The omnidirectional rotating component provides a fixed fulcrum, ensuring that the target body's motion revolves around this point.

[0091] By controlling the height changes of the two lifting components 3100, the pitch angle of the plane containing the target object can be precisely adjusted. For example, when it is necessary to increase the pitch angle, the height of both lifting components 3100 can be raised simultaneously. When it is necessary to decrease the pitch angle, the height of both lifting components 3100 can be lowered simultaneously. When it is necessary to adjust the lateral angle, the height of one lifting component 3100 can be made higher than that of the other.

[0092] During operation, the control system calculates the required height of the two lifting components 3100 based on the desired pitch angle, then controls their respective drive motors to operate at the corresponding speeds, moving the lifting rods to the calculated positions via the transmission mechanism. Simultaneously, the omnidirectional rotating component automatically adjusts its rotation angle according to the target object's movement, ensuring smooth angle adjustments.

[0093] This pitch mechanism 3000 features a simple design and precise control, enabling multi-angle adjustment of the target plane. By employing a combination of two lifting components 3100 and one universal rotation component, the number of lifting components 3100 is reduced, lowering structural complexity and cost, while maintaining the functionality and accuracy of pitch angle adjustment.

[0094] The 3000 pitch mechanism can be widely used in equipment requiring precise angle adjustment, such as optical instruments, antennas, and solar panels. This structure enables precise positioning and angle adjustment of the target, improving the equipment's efficiency and accuracy.

[0095] In one embodiment, the fixed body 1100 can be made of metal, possessing sufficient rigidity and strength to stably support the entire control gimbal structure. The fixed body 1100 has mounting positions for the telescopic drive assembly 1300, providing a stable foundation support for the entire control gimbal structure. The moving body 1200 can be made of lightweight, high-strength materials, reducing overall weight while ensuring sufficient rigidity. The moving body 1200 may also have a connection interface for mounting the rotating mechanism 2000, allowing the rotating mechanism 2000 to be directly or indirectly mounted on the moving body 1200.

[0096] See Figure 2 As shown, in one embodiment, the fixed body 1100 and the moving body 1200 can be configured as a housing structure. The fixed body 1100 has a first space with an opening inside, and the moving body 1200 has a second space with an opening inside. The first and second spaces combine between the fixed body 1100 and the moving body 1200 to form a storage space, in which the telescopic drive assembly 1300 is assembled. The storage space can not only be used to install the telescopic drive assembly 1300, but also to house other functional components such as circuit boards and batteries, achieving a compact and integrated structure. The inner wall of the storage space can be designed with a heat dissipation structure to effectively reduce the heat generated by the internal components during operation and extend the service life of the equipment.

[0097] See Figures 3 to 6 As shown, the telescopic drive assembly 1300 includes a telescopic motor 1310, a telescopic lead screw 1320, and a telescopic slide rail 1330. The moving body 1200 is movably mounted to the fixed body 1100 via the telescopic slide rail 1330. The telescopic motor 1310 is mounted to the fixed body 1100. The telescopic motor 1310 is connected to the moving body 1200 via the telescopic lead screw 1320. The telescopic lead screw 1320 can convert rotational motion into linear motion, driving the moving body 1200 to move along the telescopic trajectory.

[0098] In addition, the telescopic drive assembly 1300 can also adopt a structure such as an electric actuator. The fixed end of the electric actuator is connected to the fixed body 1100, and the movable end is connected to the moving body 1200. The telescopic movement of the electric actuator drives the moving body 1200 to reciprocate relative to the fixed body 1100. The electric actuator has the characteristics of compact structure, fast response speed, and high control precision, and can realize precise telescopic control of the gimbal structure. Those skilled in the art can design according to actual needs, and no limitation is made here.

[0099] See Figure 7 and Figure 8 As shown, in one embodiment, the telescopic slide 1330 includes a telescopic track component 1331 and a telescopic bearing component 1332, which are respectively assembled on the fixed body 1100 and the moving body 1200. The telescopic track component 1331 has a telescopic track groove 1333, and the telescopic track groove 1333 has a first track auxiliary groove 1334 and a second track auxiliary groove 1335 with opposite and symmetrical openings. The number of telescopic bearing components 1332 is configured to be several, and several telescopic bearing components 1332 are rolled in the telescopic track groove 1333 of the telescopic track component 1331. Some of the telescopic bearing components 1332 are rolled in the first track auxiliary groove 1334 and are tangent to the bottom wall of the first track auxiliary groove 1334, and other telescopic bearing components 1332 are rolled in the second track auxiliary groove 1335 and are tangent to the bottom wall of the second track auxiliary groove 1335.

[0100] Therefore, based on the assembly design of the two telescopic bearing components 1332 with the first track groove 1334 and the second track groove 1335 respectively, both load-bearing and guiding functions can be achieved. Specifically, the two openings of the first track groove 1334 and the second track groove 1335 within the telescopic track groove 1333 are vertically opposite each other in the direction of gravity and form a symmetrical arrangement. Thus, one portion of the telescopic bearing component 1332 can be rolled within the upper first track groove 1334 and tangent to the bottom wall of the groove, providing a load in the direction of gravity through line contact rolling friction during movement. The other portion of the telescopic bearing component 1332 can be rolled within the lower first track groove 1334 and tangent to the bottom wall of the groove, providing a load in the direction of gravity through line contact rolling friction during movement.

[0101] These two telescopic bearing components 1332, together with the first track groove 1334 and the second track groove 1335, can form a set. In the two parts that cooperate with the first track groove 1334 and the second track groove 1335, each part can be provided with one or more telescopic bearing components 1332.

[0102] In one embodiment, a portion of the telescopic bearing 1332 located in the first track groove 1334 is clearance-fitted with the groove sidewall of the first track groove 1334, and a portion of the telescopic bearing 1332 located in the second track groove 1335 is clearance-fitted with the groove sidewall of the second track groove 1335. Therefore, the clearance fit can constrain the telescopic bearing 1332 to move along the telescopic track groove 1333, the first track groove 1334 and the second track groove 1335, and also prevent lateral movement during load movement.

[0103] This clearance fit design allows the telescopic bearing component 1332 to have a certain amount of room to move within the first track groove 1334, enabling slight lateral adjustments while maintaining stable support, thus accommodating minor deviations that may occur during track operation. The clearance fit design also effectively reduces friction, lowers running resistance, and extends service life.

[0104] Similarly, the telescopic bearing 1332 located in the second track groove 1335 also uses a clearance fit with the groove sidewall of the second track groove 1335. This fit ensures that the telescopic bearing 1332 also has adequate room for movement within the second track groove 1335, enabling it to adjust its position during track operation and adapt to dynamic changes in the track.

[0105] This configuration allows the telescopic bearing 1332 to roll stably within the telescopic track groove 1333, reducing friction and improving motion accuracy. Different telescopic bearings 1332 are designed to be tangent to the bottom walls of the first track groove 1334 and the second track groove 1335, ensuring that the telescopic bearing 1332 will not wobble or shift during movement, thus guaranteeing the smoothness and precision of the motion.

[0106] The telescopic mechanism 1000 includes a floating component. The telescopic lead screw 1320 is driven and connected to the moving body 1200 through the floating component. The floating component acts as a buffer and adjuster between the telescopic lead screw 1320 and the moving body 1200, compensating for installation errors and minor deviations during movement, ensuring smooth and stable movement. Therefore, the design of the floating component allows the telescopic lead screw 1320 to adapt to minor deviations in the moving body 1200 during movement, avoiding jamming or damage caused by rigid connections. When the telescopic lead screw 1320 rotates, the floating component converts the rotational motion into linear motion of the moving body 1200, realizing the telescopic function.

[0107] For example, the floating component can be composed of studs, springs, nuts, etc. The main function of the spring is to compensate for machining and assembly errors and prevent the mechanism from jamming. When the moving body 1200 extends forward relative to the fixed body 1100, the telescopic screw 1320 pushes the floating component, thereby causing the moving body 1200 to extend. When the moving body 1200 retracts relative to the fixed body 1100, the telescopic screw 1320 pushes the floating component, the spring on the stud is compressed, and the spring force causes the moving body 1200 to retract. The designed spring force is greater than the lateral thrust of the load mechanism between the moving body 1200 and the fixed body 1100.

[0108] See Figures 9 to 13 As shown, in one embodiment, the rotating mechanism 2000 includes a rotating base 2400, which is mounted to the moving body 1200 via a rotating base plate 2500. A rotating worm gear component 2300 is rotatably mounted on the rotating base 2400 along a fixed axis. A limiting component 2600 is provided between the rotating worm gear component 2300 and the rotating base 2400 to limit the rotating worm gear component 2300 to rotate only along the rotation axis relative to the fixed axis of the rotating base 2400, prohibiting the rotating worm gear component 2300 from moving radially or axially along the rotation axis. Through the action of the limiting component 2600, radial and axial movement of the rotating worm gear component 2300 that may occur during operation can be effectively prevented, ensuring the motion accuracy of the rotating mechanism 2000.

[0109] See Figure 12 and Figure 8 As shown, in one embodiment, the limiting component 2600 includes a first limiting component 2610 and a second limiting component 2620. The interior of the rotating base 2400 has a seat cavity 2410. The first limiting component 2610 and the second limiting component 2620 are assembled in the seat cavity 2410. The first limiting component 2610 is radially limited between the rotating base 2400 and the rotating worm gear component 2300 to restrict the movement of the rotating worm gear component 2300 relative to the rotating base 2400 in the radial direction. The second limiting component 2620 is axially limited between the rotating base 2400 and the rotating worm gear component 2300 to restrict the movement of the rotating worm gear component 2300 relative to the rotating base 2400 in the axial direction. Therefore, after the rotary motor 2100 is started, due to the limiting effect of the first limiting component 2610 and the second limiting component 2620, the rotary worm gear component 2300 can only rotate within the rotary base 2400, and will not undergo radial and axial displacement, thereby ensuring the stability and accuracy of the rotary mechanism 2000.

[0110] See Figure 13As shown, in one embodiment, the first limiting member 2610 is configured as an annular first limiting bearing, and the second limiting member 2620 is configured as an annular second limiting bearing. The interior of the rotating base 2400 has at least a first limiting step 2420 and a second limiting step 2430. The first limiting bearing is mounted on the first limiting step 2420, and the inner wall of the first limiting bearing radially limits and abuts against the rotating worm gear 2300. The outer wall of the first limiting bearing radially limits and abuts against the rotating base 2400, thereby preventing the rotating worm gear 2300 from moving radially relative to the rotating base 2400. The second limiting bearing is mounted on the second limiting step 2430, and the inner wall of the second limiting bearing is radially rotatably mounted against the rotating worm gear 2300. The outer wall of the second limiting bearing radially rotatably mounts against the rotating base 2400, thereby preventing the rotating worm gear 2300 from moving axially relative to the rotating base 2400.

[0111] The first limiting bearing is mounted on the first limiting step 2420 of the rotating base 2400. The inner wall of the first limiting bearing radially limits and abuts against the rotating worm gear component 2300, while its outer wall radially limits and abuts against the rotating base 2400. This configuration effectively prevents the rotating worm gear component 2300 from moving radially relative to the rotating base 2400. Through this limiting method, the radial position of the rotating worm gear component 2300 is fixed, ensuring it maintains a stable central position during rotation and avoiding problems such as unstable operation or poor meshing caused by radial movement.

[0112] Meanwhile, the second limiting bearing is mounted on the second limiting step 2430 of the rotating base 2400. The inner wall of the second limiting bearing is radially rotatably assembled with the rotating worm gear component 2300, while its outer wall is radially rotatably assembled with the rotating base 2400. This configuration allows the second limiting bearing to effectively prevent the rotating worm gear component 2300 from moving axially relative to the rotating base 2400. Through this limiting method, the axial position of the rotating worm gear component 2300 is fixed, preventing axial movement during operation, ensuring the normal meshing relationship between the rotating worm gear component 2300 and other transmission components, and improving the stability and reliability of the entire transmission system.

[0113] The first and second limiting bearings form limiting contacts with the rotating worm gear component 2300 and the rotating base 2400 through their respective inner and outer side walls, thereby effectively limiting the rotating worm gear component 2300 in both radial and axial directions. This bidirectional limiting design ensures the positional accuracy of the rotating worm gear component 2300 during operation, reduces mechanical backlash, and improves transmission accuracy.

[0114] In practical applications, the first and second limit bearings can be standard rolling or sliding bearings, with the appropriate bearing type selected based on specific load conditions and working environment. These bearings not only serve a limiting function but also reduce the frictional resistance between the rotating worm gear 2300 and the rotating base 2400, improving transmission efficiency and extending the equipment's service life.

[0115] When the rotating worm gear component 2300 is in operation, the first and second limit bearings work together to form a stable support system, enabling the rotating worm gear component 2300 to rotate smoothly at the predetermined position while effectively preventing positional deviation caused by external impacts or load changes. This limit bearing structure design not only simplifies the assembly process but also improves the rigidity and stability of the entire mechanism, making it particularly suitable for mechanical equipment requiring high-precision transmission.

[0116] Through the design of the aforementioned limiting component 2600, the rotating worm gear 2300 can operate stably within the rotating base 2400, effectively avoiding transmission errors and mechanical wear caused by displacement, and improving the working accuracy and service life of the entire rotating mechanism 2000. At the same time, the limiting component 2600 has a simple structure, is easy to install, has low maintenance costs, and is highly practical.

[0117] In one embodiment, the rotating mechanism 2000 includes a transmission assembly 2700, through which the rotary motor 2100 is connected to the rotary worm gear 2200. The transmission assembly 2700 may include a gear and shaft engagement, or a pulley and belt engagement, which is not limited herein. When the rotary motor 2100 operates, its power is transmitted to the rotary worm gear 2200 via the transmission assembly 2700, driving the rotary worm gear 2200 to rotate, which in turn drives the rotary worm wheel 2300 to rotate.

[0118] See Figures 14 to 16 As shown, in one embodiment, the lifting assembly 3100 includes a pitch base 3110, a pitch motor 3120, and a pitch worm gear. The pitch base 3110 is mounted on the rotating worm gear component 2300 via a pitch base plate. The pitch worm gear includes a pitch worm gear component 3130 and a pitch worm component 3140. The pitch motor 3120 is driven to connect with the pitch worm gear component 3130, and the pitch worm gear component 3130 is driven to mesh with the pitch worm component 3140 to drive the pitch worm component 3140 to reciprocate along the lifting trajectory, directly or indirectly adjusting the linear lifting of a position of the target body.

[0119] The lifting assembly 3100 also includes a limit detection assembly 3200. The limit detection assembly 3200 includes a detection base 3210, a pitch screw, a gear set 3240, and a sensor 3250. The pitch screw includes a pitch rod 3220 and a pitch nut 3230. The pitch rod 3220 is rotatably mounted on the detection base 3210 and is connected to the pitch worm gear 3140 via the gear set 3240. The detection base 3210 has a detection space. The pitch nut 3230 is movably mounted on the pitch rod 3220 and located in the detection space. The sensor 3250 is disposed on the pitch nut 3230 and is used to move synchronously with the pitch nut 3230 in the detection space.

[0120] The pitch base 3110 is mounted on the rotating worm gear component 2300 via a pitch base plate, forming a stable foundation support. The pitch worm gear consists of two parts: a pitch worm gear component 3130 and a pitch worm component 3140, which transmit power through meshing. The pitch motor 3120 is driven and connected to the pitch worm gear component 3130. When the pitch motor 3120 starts, it drives the pitch worm gear component 3130 to rotate. The pitch worm gear component 3130 and the pitch worm component 3140 are driven and meshed. Through this meshing relationship, the rotational motion of the pitch worm gear component 3130 is converted into the linear motion of the pitch worm component 3140, thereby enabling the pitch worm component 3140 to reciprocate along a preset lifting trajectory.

[0121] The reciprocating motion of the pitch worm gear 3140 directly or indirectly drives the target body to adjust its position, realizing the linear lifting and lowering function of the target body. This structural design utilizes the self-locking characteristic of worm gear transmission to ensure that the target body can remain in its current position without slipping when the power supply is stopped, thus improving the safety and stability of the system.

[0122] The lifting assembly 3100 is also equipped with a limit detection assembly 3200 for monitoring and controlling position information during the lifting process. The limit detection assembly 3200 includes a detection base 3210, a pitch screw, a gear set 3240, and a sensor 3250. The detection base 3210 has an internal detection space to provide a location for the installation and movement of the detection element. The pitch screw consists of a pitch rod 3220 and a pitch nut 3230, with the pitch rod 3220 rotatably mounted on the detection base 3210 and connected to the pitch worm gear 3140 via the gear set 3240. When the pitch worm gear 3140 moves, it drives the pitch rod 3220 to rotate via the gear set 3240.

[0123] The pitch nut 3230 is movably mounted on the pitch screw 3220 and located in the detection space of the detection base 3210. As the pitch screw 3220 rotates, the pitch nut 3230 moves axially within the detection space. A sensor 3250 is mounted on the pitch nut 3230 and moves synchronously with it in the detection space. Through the movement of the sensor 3250, the system can monitor the position of the pitch nut 3230 in real time, thereby indirectly obtaining the current position information of the target object.

[0124] The gear set 3240 plays a crucial transmission role in the limit detection assembly 3200. It precisely transmits the motion of the pitch worm gear 3140 to the pitch screw 3220, ensuring that the rotational speed of the pitch screw 3220 maintains a certain proportional relationship with the motion speed of the pitch worm gear 3140. This transmission method not only improves the accuracy of position detection but also enhances the reliability of the entire system.

[0125] The sensor 3250 can take various forms, such as a proximity switch, photoelectric sensor, or Hall sensor. When the pitch nut 3230 moves to the preset position, the sensor 3250 will trigger a signal to notify the control system that the target body has reached the specific position. The control system can then make corresponding control decisions, such as stopping the motor or changing the direction of movement.

[0126] The design of this limit detection component 3200 enables the lifting component 3100 to precisely control the lifting height of the target object, preventing overtravel and avoiding mechanical damage. Simultaneously, through real-time feedback from the sensor component 3250, the system can achieve closed-loop control, improving positioning accuracy and motion stability.

[0127] The entire lifting assembly 3100 features a compact design, high transmission efficiency, and excellent self-locking performance and position control capabilities. Through the coordinated operation of the pitch motor 3120, pitch worm gear, and limit detection assembly 3200, precise lifting control of the target object can be achieved, meeting various precision positioning requirements.

[0128] The laser TV of this application, through its integrated control pan-tilt unit, can solve the problem of irregular image projection caused by the levelness of the wall or mounting surface during the installation and use of existing laser TVs. Unlike traditional laser TVs that require manual adjustment of casters to adjust the image, the laser TV of this application can achieve automatic and precise adjustment through the control pan-tilt unit.

[0129] When the laser TV is working, the telescopic mechanism 1000 of the control pan-tilt unit can adjust the front and rear position of the laser TV to achieve fine adjustment of the projection distance; the rotation mechanism 2000 can drive the laser TV to rotate around the rotation axis to achieve horizontal angle adjustment; the pitch mechanism 3000 changes the projection angle of the laser TV by controlling the height of the lifting component 3100 to achieve precise pitch adjustment.

[0130] This design allows the laser TV to automatically adjust the projection angle and position according to the actual installation environment, ensuring that the projected image appears as a regular rectangle on the screen, eliminating the need for manual adjustment of the casters and greatly improving the user experience. At the same time, the precise control mechanism of the pan-tilt unit ensures the accuracy and stability of the laser TV's image adjustment, avoiding the inaccuracies that can occur with traditional manual adjustments.

[0131] In practical applications, users only need to operate the laser TV's control pan-tilt unit via the control panel or remote control to achieve automatic image adjustment, eliminating the need for cumbersome manual operation and greatly simplifying the installation and use of laser TVs.

[0132] In summary, based on the aforementioned control of the gimbal, the laser TV's laser host 100 can significantly improve adjustment efficiency and accuracy compared to existing manual adjustments. For example, in fully automatic mode, calibration can be completed in approximately 30 seconds (manual adjustment takes 5-10 minutes, or even longer), and the adjustment accuracy of the mechanism can reach 0.1mm / 0.1°, far exceeding manual operation (±1cm / ±1°). Moreover, the control of the gimbal is suitable for a wider range of scenarios, such as uneven ground, screen misalignment, and accidental contact with the device, without requiring manual intervention. Through functions such as "contactless adjustment," "intelligent memory," and "real-time feedback," the user experience can be effectively improved, highlighting the product's intelligent attributes.

[0133] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0134] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
