[0026] Embodiments

[0027] As shown in Figure 1 The embodiment discloses a kind of anti-shaking device of binocular telescope, it includes fixed circuit board 1, movable piece 16 being connected in the fixed circuit board 1 can be translated, gyroscope 5 is arranged on the fixed circuit board 1, lens assembly is arranged on fixed circuit board 1 and movable piece 16, first drive assembly and second drive assembly are respectively arranged on fixed circuit board 1 and movable piece 16 and left-right symmetry, third drive assembly is arranged on fixed circuit board 1 and movable piece 16 and with the line of first drive assembly and second drive assembly Orthogonal distribution, first detection component and second detection component are respectively arranged on fixed circuit board 1 and movable piece 16 and left-right symmetry, third detection component is arranged on fixed circuit board 1 and movable piece 16 and with the line of first detection component and second detection component Orthogonal distribution.Gyroscope 5 and fixed circuit board 1 are electrically connected.

[0028] Through the above structure, first drive assembly and second drive assembly can drive movable piece 16 both ends relative fixed circuit board 1 in up-down direction Synchronous translation, third drive assembly can drive movable piece 16 relative fixed circuit board 1 in left-right direction translation.

[0029] Specifically, the fixed circuit board 1 is connected with the movable element 16 through the connecting element 15. When arranged, a plurality of hanging ears 18 are arranged on the fixed circuit board 1 and the movable element 16 respectively, and the two ends of the connecting element 15 are connected with the hanging ears 18 on the fixed circuit board 1 and the movable element 16 respectively. The plurality of connecting elements 15 can be uniformly distributed to enable the fixed circuit board 1 and the movable element 16 to be stably connected. In the embodiment, the connecting element 15 is implemented by a spring.

[0030] In order to enable the movable element 16 to smoothly realize translation, a plurality of ball grooves 10 are arranged on the movable element 16 or the fixed circuit board 1, and a ball 9 is arranged in each ball groove 10; the ball 9 is at least partially protruded from the ball groove 10 to enable the movable element 16 and the fixed circuit board 1 to be separated by the ball 9. The ball 9 can rotate in the ball groove 10, and since the connecting element 15 connects the movable element 16 and the fixed circuit board 1 together, the ball 9 will not fall out of the ball groove 10, and can also reduce the friction between the movable element 16 and the fixed circuit board 1, so that the movable element 16 can smoothly translate.

[0031] In order to further limit the translation of the movable element 16 and prevent the movable element 16 from being separated from the fixed circuit board 1, a limiting hole 3 is arranged on the fixed circuit board 1, and a mounting seat 12 is arranged on the movable element 16. When arranged, the connecting end of a bolt 4 is connected with the mounting seat 12 after passing through the limiting hole 3, and the bolt 4 is gap-fitted with the limiting hole 3. When the movable element 16 translates, the bolt 4 moves in the limiting hole 3, and when the translation amount of the movable element 16 is too large, the bolt 4 abuts against the limiting hole 3, thereby limiting the movement of the movable element 16.

[0032] Specifically, the size of the nut of the bolt 4 is greater than the hole diameter of the limiting hole 3, so that the movable element 16 and the fixed circuit board 1 can be prevented from being separated.

[0034] As shown in the figure, Figure 1 In the embodiment, the first driving assembly includes a first driving magnetic steel 7 arranged on the movable element 16 and a first driving coil arranged on the fixed circuit board 1 and opposite to the first driving magnetic steel 7. The second driving assembly includes a second driving magnetic steel 13 arranged on the movable element 16 and a second driving coil arranged on the fixed circuit board 1 and opposite to the second driving magnetic steel 13. The third driving assembly includes a third driving magnetic steel 11 arranged on the movable element 16 and a third driving coil arranged on the fixed circuit board 1 and opposite to the third driving magnetic steel 11.

[0035] In addition, the first detection component includes a first sensing magnet 6 disposed on the movable part 16 and a first Hall element disposed on the fixed circuit board 1 and opposite to the first sensing magnet 6; the second detection component includes a second sensing magnet 17 disposed on the movable part 16 and a second Hall element disposed on the fixed circuit board 1 and opposite to the second sensing magnet 17; the third detection component includes a third sensing magnet 8 disposed on the movable part 16 and a third Hall element disposed on the fixed circuit board 1 and opposite to the third sensing magnet 8.

[0036] The first drive coil, the second drive coil, the third drive coil, the first Hall element, the second Hall element, and the third Hall element are all electrically connected to the fixed circuit board 1. The first Hall element, the second Hall element, and the third Hall element are used to detect the movement information of the first sensing magnet 6, the second sensing magnet 17, and the third sensing magnet 8, respectively. When the movable part 16 moves, the first sensing magnet 6, the second sensing magnet 17, and the third sensing magnet 8 on it also move accordingly. The first Hall element, the second Hall element, and the third Hall element can detect the movement information of the movable part 16 in the left-right direction and the up-down direction, thereby obtaining the movement information of the lens 14. The fixed circuit board 1 is provided with a corresponding control circuit, so the fixed circuit board 1 can obtain the detection information of the three Hall elements and the gyroscope 5, and use the obtained information to control the first drive coil, the second drive coil, and the third drive coil to conduct electricity. The first drive coil, the second drive coil, and the third drive coil respectively drive the corresponding first drive magnet 7, the second drive magnet 13, and the third drive magnet 11, thereby controlling the movement of the movable part 16. Both the sensing magnet and the driving magnet are magnetized in the horizontal direction.

[0037] The image stabilization device in this embodiment can be installed between the objective lens 19 and the eyepiece 20 of the binoculars, such as... Figure 2 As shown in the diagram. During installation, the fixed circuit board 1 is fixedly installed inside the binocular telescope housing, while the movable component 16 can translate relative to the fixed circuit board 1. When the binocular telescope shakes, the gyroscope 5 detects the shaking information, and the fixed circuit board 1 determines the target amount by which the lens 14 needs to move based on this information. Simultaneously, the first Hall element, the second Hall element, and the third Hall element detect the translation data of the movable component 16, i.e., the movement data of the lens 7. The fixed circuit board 1 uses this data as feedback to perform a feedback control algorithm to obtain the driving amount of the three driving magnets. This, in turn, drives the corresponding driving magnets to translate via three driving coils, causing the movable component 16 to translate left and right or up and down, thus moving the lens 14. This counteracts the field-of-view shaking caused by the shaking of the binocular telescope, achieving image stabilization.

[0038] The embodiment directly takes the circuit board as the mounting main body of the electronic device, fully utilizes the characteristics of the circuit board, and makes the anti-shake assembly have higher integration and more compact structure; meanwhile, the utility model discloses directly install electronic components such as driving coil, hall element and gyroscope on the circuit board, optimizes the structure layout, and the structure is simpler.
