[0003]

[0001] The present invention relates to the technical field of optical image stabilization technology, and is particularly suitable for devices that require synchronous anti-vibration of two optical paths such as binoculars. Specifically, the present invention relates to a binocular anti-vibration component prism that realizes the synchronous movement of a dual prism by a parallel link mechanism and performs parallel driving by adopting a split-axis control strategy.

Background Art

[0002] In modern precision optical devices, especially in high-precision devices such as telescopes, anti-vibration technology is an important means to improve the stability and accuracy of observations. With the development of science and technology, the research and application of anti-vibration systems have been gradually deepening. However, at present, most of the conventional anti-vibration technologies still have some deficiencies, especially in terms of anti-vibration effect, hardware complexity, and system stability.

[0003] In conventional anti-vibration telescopes, a method of directly fixing a complex gyroscope sensor to a prism or a lens is generally adopted. This method not only requires connecting a plurality of circuit boards, increasing the complexity of the system, but also affects the reliability and stability of the system to a certain extent. And the transmission algorithm of conventional anti-vibration telescopes usually depends on the screw fixation method to ensure transmission accuracy. However, with this method, it is difficult to improve the transmission accuracy and simplify the assembly process at the same time.

[0004] In addition, many of the control methods for the rotation axis by conventional anti-vibration systems depend on complex feedback algorithms, and it is often necessary to control the inner shaft and the outer shaft separately, which not only increases the complexity of the system, but may also affect the synchronism and accuracy in actual use.

[0005] [[ID=​ [Overview of the project]

[0006] In view of this, the present invention aims to provide a parallel-driven binocular image-stabilized component prism that effectively simplifies the hardware configuration, improves transmission accuracy, simplifies the control scheme, and enables more accurate vibration isolation control. Through its innovative transmission algorithm, simplified control scheme, and optimized bearing assembly method, this invention overcomes the limitations of conventional vibration isolation technology, has prospects for a wide range of applications, and is particularly suitable for precision optical instruments.

[0009] In a further embodiment of the present invention, the rotation axis bearings of the left prism shell and the right prism shell are arranged in two rows, one above the other, to eliminate the oscillation error in the front-to-back direction of the prism shell, and the bearings at both ends of the connecting rod are arranged in a left-to-right configuration to reduce the rotation radius of the azimuth axis.

[0010] In a further aspect of the present invention, the inner shaft sensing magnet is located in only one prism shell and transmits its movement to the other prism shell via a connecting rod for synchronization, thereby achieving synchronized detection of dual prism angles.

[0011] In a further aspect of the present invention, a sub-axis control strategy is employed for the azimuth axis and pitch axis of the binocular image-stabilizing component prism, with feedforward-feedback composite control being employed for the azimuth axis and differential feedback tracking control being employed for the pitch axis.

[0012] In a further aspect of this invention, the hinge bearing between the rotating frame and the outer frame is a central shaft sleeve insertion type structure, which replaces fixing by tightening screws.

[0014] In a further aspect of the present invention, the binocular image-stabilizing component prism includes the following segmental control strategy.

[0015] Directional axis control: The displacement target is generated by feedforward calculation using the angular velocity of the azimuth axis detected by the gyroscope sensor.

[0016] The actual angle of the prism shell detected by the inner shaft hole element is used as a feedback amount, and the inner shaft drive coil is driven by a closed-loop control algorithm.

[0018] The actual angular velocity of the pitch axis detected by the gyroscope sensor is used as feedback, and the out-shaft drive coil is driven by a tracking control algorithm.

[0019] In a further aspect of this invention, the feedforward calculation of the azimuth axis employs an angular velocity integration algorithm and converts the output of the gyroscope sensor into a displacement compensation amount.

[0020] The differential calculation of the pitch axis employs an angle difference algorithm to convert the output of the Hall element into an angular velocity command.

[0021] In a further aspect of this invention, the data from the gyroscope sensor is used simultaneously for feedforward of the azimuth axis and feedback of the pitch axis, thereby realizing multi-use of a single sensor. [Effects of the Invention]

[0022] Compared to conventional technology, the parallel-driven binocular image-stabilizing component prism proposed in this invention has the following beneficial effects.

[0023] 1. The present invention adopts a parallel link mechanism to achieve accurate synchronous movement of the left and right prisms. This structure eliminates the angular distortion caused by the play of the prism bearings in the conventional anti-vibration system, avoids the mismatch of the binocular image fields, thereby greatly improving the synchronization, ensuring the image stability for the binoculars to maintain coincidence at different angles, and greatly improving the synchronization accuracy of the dual prisms.

[0024] 2. The present invention adopts a split-axis control strategy, that is, the azimuth axis and the pitch axis are independently controlled respectively. The azimuth axis realizes accurate angle compensation by means of a composite control algorithm of feedforward and feedback, and the pitch axis adopts a differential and feedback control method to achieve accurate tracking. Such decoupling control significantly reduces the mutual interference and error between the two-axis control, makes the anti-vibration effect more stable and the response faster, and reduces the error caused by the coupling of control by the decoupling control of the azimuth axis and the pitch axis.

[0025] 3. By designing the prism shell bearings arranged in two upper and lower rows and the connecting rod bearings arranged on the left and right, the angular distortion caused by the play of the bearings, mechanical transmission error, and eccentricity is effectively reduced. Such a design not only improves the transmission accuracy of the components, but also eliminates the sway error of the prism in the conventional design, guarantees the stability of the anti-vibration effect. Also, by fixing the sensing magnet on the prism shell and providing the driving magnet in the connecting rod, the detection error caused by the play of the connecting rod bearing is effectively avoided. By optimizing the relative position of the Hall element and the driving coil, it enables the sensing system to accurately feedback the angle information in real time, thereby improving the response speed and stability of the anti-vibration system.

[0026] 4. By integrating all elements such as sensors, drive coils, control chips, etc. onto a single integrated circuit board, this invention not only reduces the complexity of wiring, but also eliminates the risks of cable interference and loosening in the conventional design, improving the reliability of the system. The integrated design of the integrated circuit board reduces the connections between multiple circuit boards, further improving the compactness and anti-vibration effect of the product. By adopting the feedforward-feedback composite control strategy and the differential control strategy, this invention has excellent dynamic response performance in two-axis control. Especially during high-speed movement or in a rapidly changing environment, it can quickly capture angle changes and perform accurate compensation, avoiding the image distortion and instability of the conventional anti-vibration system caused by response delay.

[0027] 5. This invention adopts a highly integrated design, reducing the use of a large number of individual components in the conventional anti-vibration system. Through the optimization of the magnet layout and the simplification of the wiring structure, the hardware cost is reduced by about 30%. At the same time, due to the modularization of system components and the integration of circuits, the assembly efficiency is improved by about 50%, making the production process simpler and having higher operability. Here, the installation method of the upper and lower bearings of the prism shell and the side placement of the sensing magnet eliminates the front-back swing error caused by the play of the connecting rod bearing, improving the angle detection accuracy of the azimuth axis. By installing the sensing magnet only on a single prism shell and transmitting the movement through a rigid connecting rod, the calibration error of the dual sensors is avoided and the angular synchronization deviation is reduced. Also, by integrating the gyroscope sensor, drive coil, and Hall element onto a single integrated circuit board, the fixed cable between the gyroscope and the prism in the conventional scheme is eliminated, reducing the circuit interface and the failure rate. The replacement of the middle-axis sleeve insertion type bearing with a screw tightening structure reduces the coaxiality error of the bearing and improves the assembly efficiency.

[0028] 6. This invention adopts a left and right bearing layout for the connecting rod, thereby reducing the rotation radius of the azimuth axis and decreasing the axial space utilization of the component, making it suitable for compact binocular equipment. Furthermore, by employing feedforward and feedback composite control, it avoids zero gyroscope drift by generating the target angular velocity using Hall's angular derivative, and improves anti-interference by correcting frame vibrations in real time through gyroscope feedback. By using gyroscope data synchronously with the feedforward of the azimuth axis and the feedback of the pitch axis, the hardware cost of the gyroscope can be reduced by one unit, and power consumption can be lowered. The dual prisms deflect in absolute synchronization due to the constraint of the connecting rod, reducing the parallel shift error of the field of view, thus completely eliminating the misalignment of the binocular field of view. The central axis sleeve-inserted bearing improves vibration resistance, and there is no performance attenuation in random vibrations of 5 to 500 Hz. The binocular image stabilization component of this invention can be applied not only to binoculars but also to a wide range of optical equipment such as drones and cameras. Its high stability and highly precise vibration isolation effect enable it to maintain good operating performance in all harsh environments, thereby significantly improving the reliability and service life of the equipment.

[0035] The following clearly and completely describes the technical solutions in the embodiments of this application with reference to the drawings of the embodiments of this application, and it is clear that the embodiments described are only a selection of embodiments of this application, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of this application, without any creative work, are all within the scope of protection of this application.

[0036] The flowcharts shown are illustrative only and do not need to include all content and operations / procedures, nor do they need to be performed in the order they are described. For example, certain operations / procedures can be broken down, combined, or partially combined, so the actual order in which they are performed may vary depending on the actual situation.

[0037] Hereinafter, several embodiments of this application will be described in detail with reference to the drawings. Where there is no conflict, the embodiments and features described below can be combined with each other.

[0038] This invention proposes a parallel-driven binocular image-stabilizing component prism that not only enables flexible switching between dual sensors but also intelligently senses changes in the operating environment (e.g., desktop material, color) and configuration settings (e.g., LOD settings), and uses a dynamic data compensation algorithm to eliminate the influence of these changes on the cursor's movement trajectory, ensuring that the user obtains a consistent and predictable operating feel.

[0039] Referring to Figures 1 to 6, an embodiment of the present invention is: The left prism shell 1 and the right prism shell 2 are symmetrically arranged and mounted within the rotating frame 3 via a rotating shaft bearing 4, A bridging-type connecting rod 5 is connected to the left prism shell 1 and the right prism shell 2 via bearings at both ends, and drives the two prism shells to rotate synchronously around their respective axes of rotation, thereby realizing movement of the azimuth axis. The left and right side walls are hinged to the outer frame 7 via side bearings 6, and the rotating frame 3 enables rotation of the pitch axis, A fixedly mounted rotating frame 3 is an integrated circuit board 8 which integrates an inner shaft drive coil 9, an out shaft drive coil 10, an inner shaft Hall element 11, an out shaft Hall element 12, and a gyroscope sensor 13. An inner shaft drive magnet 14 is provided in the center of the connecting rod 5 and corresponds to the inner shaft drive coil 9 on the integrated circuit board 8, An inner shaft sensing magnet 15 is provided on the side wall of the left prism shell 1 or the right prism shell 2, and corresponds to the inner shaft hole element 11. The present invention provides a parallel-drive type binocular image-stabilizing component prism comprising an out-shaft magnet 16 provided on an external frame 7, which corresponds to an out-shaft drive coil 10 and an out-shaft Hall element 12.

[0040] In this invention, the left prism shell 1 and the right prism shell 2 achieve rotation of the azimuth axis by pushing and pulling with a connecting rod 5, resulting in a small rotation radius, good optical effect, simplicity, and high reliability. The inner shaft drive coil 9, outer shaft drive coil 10, inner shaft Hall element 11, outer shaft Hall element 12, and gyroscope sensor 13 are arranged on a main control integrated circuit board 8 fixed to the rotating frame 3. The inner rotation axis utilizes a feedforward servo of gyroscope data, and the outer rotation axis utilizes feedback control using gyroscope data, thereby achieving dual-axis drive and vibration damping control. This simplifies the sensor configuration, avoids the connection of multiple circuit boards, simplifies the hardware, and increases reliability. The rotation structure adopts a method of providing a central shaft inside and an outer shaft sleeve, improving transmission accuracy and reducing assembly complexity compared to conventional screw fixing methods. By integrating all elements such as sensors, drive coils, and control chips onto a single integrated circuit board 8, not only is the complexity of wiring reduced, but the risk of cable interference and loosening in conventional designs is eliminated, improving system reliability. The integrated design of the integrated circuit board 8 reduces the number of connections between multiple circuit boards, further improving the compactness and vibration isolation effect of the product. By adopting a feedforward-feedback combined control strategy and a differential control strategy, this invention has excellent dynamic response performance in two-axis control. In particular, during high-speed motion or in rapidly changing environments, it can quickly capture angular changes and provide accurate compensation, avoiding image distortion and instability caused by response delays in conventional vibration isolation systems.

[0041] In this embodiment, the rotation axis bearings 4 of the left prism shell 1 and the right prism shell 2 are arranged in a two-row, vertical configuration to eliminate oscillation errors in the front-to-back direction of the prism shells, and the bearings at both ends of the connecting rod 5 are arranged in a left-to-right configuration to reduce the rotation radius of the azimuth axis. Of these, the hinge bearing between the rotating frame 3 and the outer frame 7 is a central shaft sleeve insertion type structure, replacing fixing by tightening screws. By designing the prism shell bearings in a two-row, vertical configuration and the connecting rod 5 bearings in a left-to-right configuration, bearing play, mechanical transmission errors, and angular distortion caused by eccentricity are effectively reduced. Such a design not only improves the transmission accuracy of the components but also eliminates prism oscillation errors in conventional designs, ensuring the stability of the vibration damping effect. Furthermore, by fixing the sensing magnet to the prism shell and providing the drive magnet inside the connecting rod 5, detection errors caused by bearing play in the connecting rod 5 are effectively avoided. By optimizing the relative position of the Hall element and the drive coil, the sensing system can accurately feed back angular information in real time, thereby improving the response speed and stability of the vibration isolation system.

[0042] Of these, the inner shaft sensing magnet 15 is positioned only on a single prism shell and transmits its movement to the other prism shell via a connecting rod 5 for synchronization, thereby achieving synchronized detection of dual prism angles. This invention achieves precise synchronized movement of the left and right prisms by employing a parallel link mechanism. This structure eliminates angular distortion caused by play in the prism bearings in conventional vibration isolation systems, avoids discrepancies in the field of view of the binocular images, thereby greatly improving synchronization, ensuring image stability so that the binoculars remain aligned at different angles, and greatly improving the synchronization accuracy of the dual prisms.

[0043] In this embodiment, a sub-axis control strategy is employed for the azimuth axis and pitch axis of the binocular image-stabilizing component prism, with a feedforward-feedback composite control being employed for the azimuth axis and a differential feedback tracking control being employed for the pitch axis. This invention employs a sub-axis control strategy, meaning that the azimuth axis and pitch axis are controlled independently. Accurate angle compensation is achieved for the azimuth axis by a feedforward and feedback composite control algorithm, and accurate tracking is achieved for the pitch axis by employing a differential and feedback control method. Such decoupling control significantly reduces mutual interference and errors between the two axes, making the image stabilization effect more stable and the response faster, and the decoupling control of the azimuth axis and pitch axis reduces errors caused by control coupling.

[0044] In this embodiment, the binocular image-stabilizing component prism is provided in the optical path between the objective lens and the eyepiece lens of the binoculars, and the binoculars further comprises a focus unit and a housing, the housing of which is provided with a battery compartment and a switch for supplying power to the integrated circuit board 8.

[0045] In this embodiment, referring to Figures 1 to 7, the binocular image stabilization component prism includes the following segmental control strategy.

[0046] Directional axis control: The displacement target is generated by feedforward calculation using the angular velocity of the azimuth axis detected by the gyroscope sensor.

[0047] The actual angle of the prism shell detected by the inner shaft hole element 11 is used as a feedback amount, and the inner shaft drive coil 9 is driven by a closed-loop control algorithm.

[0048] Pitch axis control: The angle of the rotating frame 3 detected by the out-shaft Hall element 12 is used to generate a target angular velocity quantity through differential calculation.

[0049] The actual angular velocity of the pitch axis detected by the gyroscope sensor is used as feedback, and the out-shaft drive coil 10 is driven by a tracking control algorithm.

[0050] In this embodiment, the feedforward calculation of the azimuth axis employs an angular velocity integration algorithm to convert the output of the gyroscope sensor into a displacement compensation amount.

[0051] The differential calculation of the pitch axis employs an angle difference algorithm to convert the output of the Hall element into an angular velocity command.

[0052] In this embodiment, the data from the gyroscope sensor is used simultaneously for feedforward of the azimuth axis and feedback of the pitch axis, realizing multi-use of a single sensor.

[0053] This invention employs a highly integrated design, reducing the use of numerous individual components found in conventional vibration isolation systems. Optimization of magnet layout and simplification of wiring structure reduce hardware costs by approximately 30%. Simultaneously, modularization of system components and integration of circuits improves assembly efficiency by approximately 50%, thus simplifying the production process and providing greater operability. The installation method of lateral placement of the upper and lower bearings of the prism shell and the sensing magnet eliminates forward and backward oscillation errors caused by play in the connecting rod 5 bearing, improving the accuracy of angle detection on the azimuth axis. By installing the sensing magnet on only a single prism shell and transmitting the movement via the rigid connecting rod 5, calibration errors of dual sensors are avoided, and angular synchronization errors are reduced. Furthermore, by integrating the gyroscope sensor, drive coil, and Hall element onto a single integrated circuit board 8, the fixed cable between the gyroscope and prism in the conventional scheme is eliminated, reducing the circuit interface and lowering the failure rate. The replacement of the central shaft sleeve-inserted bearing with a screw-tightened structure reduces the coaxiality error of the bearing and improves assembly efficiency.

[0054] This invention employs a left-right bearing layout for the connecting rod 5, thereby reducing the rotation radius of the azimuth axis and decreasing the axial space utilization of the component, making it suitable for compact binocular equipment. Furthermore, it employs feedforward-feedback composite control, avoiding zero gyroscope drift by generating the target angular velocity using Hall's angular derivative, and improving anti-interference by correcting frame vibrations in real time through gyroscope feedback. By using gyroscope data synchronously with the feedforward of the azimuth axis and the feedback of the pitch axis, the hardware cost of the gyroscope can be reduced by one unit, and power consumption can be lowered. The dual prisms deflect in absolute synchronization due to the constraint of the connecting rod 5, reducing the parallel shift error of the field of view, thus completely eliminating the misalignment of the binocular field of view. The central axis sleeve-inserted bearing improves vibration resistance, and there is no performance attenuation in random vibrations of 5 to 500 Hz. The binocular image stabilization component of this invention is not only applicable to binoculars but can also be widely applied to various optical instruments such as drones and cameras. Its high stability and highly precise vibration isolation effect enable it to maintain good operating performance in all harsh environments, thereby significantly improving the reliability and service life of the equipment.
