Description

Technical Field

[0001] The present invention relates to the technical field of telescopes, and specifically to an anti-shake structure of a telescope and its control method. Background Art

[0002] A telescope is an optical instrument that collects and focuses light through a combination of lenses or mirrors, making distant objects appear closer, larger, or clearer. When holding a telescope by hand, the shaking of the hand will affect the observation effect. An anti-shake structure can compensate for this shaking, making hand-held observation more stable and comfortable, so an anti-shake structure of a telescope will be used.

[0003] The anti-shake structure of a telescope refers to a special mechanical or electronic system added to the telescope to reduce or eliminate the shaking of the telescope caused by hand tremors or other external factors. In the existing telescope technology, the anti-shake effect of the telescope is not good, and it is easy to cause image blurring due to shaking during use. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an anti-shake structure of a telescope and its control method, which solves the problems of poor anti-shake effect and troublesome adjustment during the use of the telescope.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: An anti-shake structure of a telescope includes a second frame and a first frame. Inside both the second frame and the first frame, a driving motor is fixedly connected. The output end of the driving motor is fixedly provided with a magnet. An outer wall of the magnet is provided with a prism group or a focusing lens group. The outer wall of the magnet is arranged on the outer wall of the first frame. Inside the prism group or the focusing lens group, a bearing is rotatably connected. An outer wall of the bearing is fixedly connected inside the second frame. The inside of the first frame is rotatably connected to the outer wall of the bearing. An outer wall of the prism group or the focusing lens group is fixedly connected with a prism seat or a focusing lens seat. The outer wall of the prism seat or the focusing lens seat is arranged inside the second frame. A connecting cross beam is fixedly connected between the prism seats or the focusing lens seats.

[0006] Preferably, the driving motor is installed inside the first frame and the driving motor is installed inside the second frame.

[0007] Preferably, a gyroscope and an angular velocity sensor are arranged on an outer wall of the prism group or the focusing lens group, and the gyroscope and the angular velocity sensor are used to collect shaking signals on the X-axis and the Y-axis.

[0008] Preferably, an outer wall of the gyroscope and the angular velocity sensor is electrically connected to a motor control board, and the inside of the motor control board is electrically connected to an outer wall of the driving motor.

[0009] Preferably, the outer wall of the motor control board is installed inside the second frame, and the motor control board is connected to the gyroscope and the angular velocity sensor by wiring, so that the entire circuit part is dispersed.

[0010] Preferably, the driving motor and the magnet are magnetically connected to adsorb the prism group or the focusing lens group, thereby driving the prism group or the focusing lens group to rotate.

[0011] Preferably, the driving motor pushes a group of prism groups or focusing lens groups to rotate, thereby driving the second group of prism groups or focusing lens groups to rotate. The first frame is pushed to rotate in the Y-axis direction by the driving motor, driving the rotation of the two prism seats or focusing lens seats in the Y-axis direction, so that the X-axis direction and the Y-axis direction can work independently.

[0012] Preferably, the prism seat or the focusing lens seat is installed inside the first frame, and the prism seats or the focusing lens seats are rigidly connected by the parallelogram principle.

[0013] Preferably, the prism group or the focusing lens group is supported and fixed by bearings to ensure synchronous movement in the X-axis direction inside the first frame.

[0014] A control method for the anti-shake structure of a telescope, used for the anti-shake structure of a telescope, the method comprising the following steps: S1. Power on and calibrate the zero position; S2. The gyroscope and the angular velocity sensor collect jitter signals, and the jitter signals include direction and angular acceleration; S3. The MCU compares the zero position with the newly collected signal according to a preset threshold, and after processing and calculation, sends a motion execution signal to the driving motor: S3.1 If it exceeds the set threshold, return to S1 again; S3.2 Execute downward within the set threshold range; S4. The driving motor executes the motion instruction to drive the component to move; S5. The gyroscope and the angular velocity sensor collect signals in real time, and return to the calibrated zero position until the moving component is detected, and send an instruction; S6. The driving motor parks and returns to S2 again.

[0015] Working principle: When the telescope module is jittered during use, gyroscopes and acceleration sensors on the prism base or the focusing lens base collect jitter signals on the X-axis and Y-axis. The gyroscopes are connected to the single-chip microcomputer processor circuit board, the single-chip microcomputer circuit board is connected to the motor control board, and the motor control board is connected to two driving motors. The gyroscopes and acceleration sensors transmit the real-time jitter signals to the single-chip microcomputer for processing. After calculation, the single-chip microcomputer outputs control signals to the motor control board, and the motor control board controls the movement of the driving motors. When the driving motors drive the prism group or the focusing lens back to the calibrated position before jitter, the gyroscopes will collect signals and return to the original position, and the entire system recalibrates the initial position. The gyroscopes and acceleration sensors collect the direction, angle, and acceleration of the jitter signals, and the single-chip microcomputer calculates the numerical value of the motor compensation according to the data. Through the control of this closed-loop system, the movement of the telescope module is corrected in real time, ensuring that it still has good anti-shake function under intense movement conditions; Through the linkage drive adopted in the structure, this anti-shake module can be used not only in the prism anti-shake system, including roof prisms, Abbe prisms, and Porro prisms, but also in the focusing lens anti-shake system. It can be achieved simply by replacing the prism base or the focusing lens base, achieving a modular product design, facilitating the use in different aspects, and also providing convenience for the diversified customized production of products.

[0016] The present invention provides an anti-shake structure of a telescope and its control method. It has the following beneficial effects: 1. By applying the characteristic that the two sides of a parallelogram always remain parallel, the present invention enables the two prism bases or focusing lens bases to accurately ensure that the optical axes of the two prism groups or focusing lens groups are always parallel. The optical axis of a single prism group or focusing lens group can be adjusted separately, achieving the effect of ensuring consistent displacement correction of the two prism groups or focusing lens groups, with stronger stability. The structure is simple, making the optical axis calibration easier.

[0017] 2. Through the linkage drive, the present invention can be used not only in the prism anti-shake system but also in the focusing lens anti-shake system. It can be achieved simply by replacing the prism base or the focusing lens base, achieving a modular product design, facilitating the use in different aspects, and providing convenience for the diversified customized production of products.

Through the driving effect of the driving motor 1, the magnet 5 can be driven to rotate. The magnet 5 in the X-axis direction and the magnet 5 in the Y-axis direction respectively play a role in fixing the prism group or the focusing lens group 4 and the first frame 3, and can respectively drive the prism group or the focusing lens group 4 and the first frame 3 to rotate.
