Description

Technical Field

[0001] The utility model relates to the technical field of image anti-shake, in particular to an anti-shake component and a telescope. Background Art

[0002] When using a telescope or a laser rangefinder with a telescope function by hand, even the slightest shake of the hand can cause severe shaking of the field of view, making it difficult to observe detailed targets or to accurately measure distances.

[0003] In order to solve the jitter problem of telescopes and laser rangefinders, some anti-shake mechanisms and products based on the lens shift principle have appeared on the market. For example, the patent technology with application number CN202222666386.2 discloses an image stabilization structure for laser rangefinders. This technology solves the hand-held jitter problem of laser rangefinder telescopes by setting a lens shift assembly in the rangefinder and controlling the movement of the image stabilization lens in the lens shift assembly. However, the coils, position sensors and other electronic components in the lens shift assembly of this technology are all set on a movable seat. When the movable seat moves, it is easy to affect the signal transmission of each electronic component, thereby affecting the stability of the entire image stabilization structure. In addition, the lens shift assembly of this technology requires the coils, position sensors and other electronic components to be controlled by an external independently set circuit board (controller). This means that the coils, position sensors and other electronic components must be connected to the circuit board through flexible cables, which invisibly increases the complexity and cost of processing and reduces the integration and stability of the components.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Example 1

[0035] like Figure 1-3 As shown, this embodiment discloses an anti-shake assembly, which includes: a circuit board 5, a movable mounting plate 6, a lens 7, two driving magnets 13, two sensing magnets 18, two driving coils 19, two Hall elements 23 and a gyroscope 21.

[0036] The circuit board 5 has an escape opening 11; the circuit board 5 and the movable mounting plate 6 are connected by at least two tension springs 15. The tension springs 15 can be set as two or four. In this embodiment, two tension springs 15 are set symmetrically with the escape opening 11 as the center. In the specific configuration, the circuit board 5 and the movable mounting plate 6 are both provided with tension spring hanging beams 9, and the ends of the tension spring 15 are respectively connected to the tension spring hanging beams 9 on the circuit board 5 and the movable mounting plate 6. Figure 1 As shown, since the tension spring 15 can swing, the movable mounting plate 6 can move relative to the circuit board 5.

[0037] In addition, if Figure 2 As shown, the movable mounting plate 6 is provided with a lens mounting opening 14 corresponding to the avoidance opening 11 , and the lens 7 is fixedly mounted in the lens mounting opening 14 , so that when the movable mounting plate 6 moves, the lens 7 can be driven to move.

[0038] The two driving magnets 13 are orthogonally distributed on the side of the movable mounting plate 6 facing the circuit board 5, and the two sensing magnets 18 are also orthogonally distributed on the side of the movable mounting plate 6 facing the circuit board 5. Correspondingly, the two driving coils 19 are arranged on the side of the circuit board 5 facing the movable mounting plate 6, and the positions of the two driving coils 19 correspond one-to-one to the positions of the two driving magnets 13. The two Hall elements 23 are also arranged on the side of the circuit board 5 facing the movable mounting plate 6, and the positions of the two Hall elements 23 correspond one-to-one to the positions of the two sensing magnets 18. The gyroscope 21 is also arranged on the circuit board 5. The two driving coils 19, the two Hall elements 23 and the gyroscope 21 are all electrically connected to the circuit board 5, and the two Hall elements 23 can be SS49E Hall elements.

[0039] Through the above structure, one driving coil 19 and its corresponding driving magnet 13 form a driving structure in one direction, such as a left-right driving structure, which can drive the movable mounting plate 6 to move in the left-right direction. Another driving coil 19 and its corresponding driving magnet 13 form a driving structure in another direction, such as a top-bottom driving structure, which can drive the movable mounting plate 6 to move in the top-bottom direction. The two Hall elements 23 are respectively used to detect the movement information of the two sensing magnets 18. When the movable mounting plate 6 moves, the two sensing magnets 18 thereon also move accordingly. The two Hall elements 23 can detect the movement information of the movable mounting plate 6 in the left-right direction and the top-bottom direction, thereby obtaining the movement information of the lens 7.

[0040] The circuit board 5 is provided with a corresponding control circuit and a single chip microcomputer 22 , so that the circuit board 5 can obtain the detection information of the Hall element 23 and the gyroscope 21 , and control the operation of the driving coil 19 through the obtained information, thereby controlling the movement of the movable mounting plate 6 .

[0041] This embodiment integrates the circuit board 5 into the assembly and uses it as a fixed mounting plate. This fully utilizes the characteristics of the circuit board, resulting in a higher level of integration and a more compact structure for the anti-shake assembly. Furthermore, this embodiment mounts electronic components such as the drive coil 19, Hall effect element 23, and gyroscope 21 directly on the circuit board 5, optimizing the structural layout and eliminating the need for cables to lead the electronic components out and connect them to the circuit board 5. This reduces manufacturing complexity and cost, while improving operational stability.

[0042] In order to make the movable mounting plate 6 move more smoothly, as Figure 2 、 3As shown, at least three mounting plate ball seats 12 are evenly arranged on the movable mounting plate 6, and a corresponding circuit board ball seat 20 is provided on the circuit board 5, whose number and position correspond one-to-one to the mounting plate ball seat 12, and a ball 17 is provided between each mounting plate ball seat 12 and the circuit board ball seat 20.

[0043] Specifically, both mounting plate ball seat 12 and circuit board ball seat 20 are provided with ball mounting grooves. The diameter of the ball mounting grooves is greater than the diameter of ball 17, allowing ball 17 to roll within the grooves. Furthermore, the diameter of ball 17 is greater than the combined depth of the ball mounting grooves on mounting plate ball seat 12 and circuit board ball seat 20. Furthermore, the combined height of mounting plate ball seat 12 and circuit board ball seat 20 is greater than the length of tension spring 15 in its natural state. Thus, through the above-described structure, circuit board 5 and movable mounting plate 6 can be isolated by ball 17, while tension spring 15 prevents them from separating. The rolling characteristics of ball 17 enable better movement of movable mounting plate 6.

[0044] In addition, if Figure 2 、 3 As shown, the circuit board 5 is provided with a limit hole 8, and the number of the limit holes 8 can be set to two, and the two limit holes 8 are symmetrically distributed with the avoidance opening 11 as the center. Accordingly, the movable mounting plate 6 is provided with two limit screw seats 16 corresponding to the limit holes 8. During installation, the screw rod of the limit screw 10 is passed through the limit hole 8 and screwed into the limit screw seat 16. The screw cap of the limit screw 10 does not contact the surface of the circuit board 5, as shown in FIG. Figure 1 In the specific configuration, the limiting hole 8 and the screw of the limiting screw 10 are clearance-fitted, i.e., the diameter of the limiting hole 8 is larger than the diameter of the screw of the limiting screw 10, so that the movable mounting plate 6 can move within a certain range. In this embodiment, the limiting screw 10 cooperates with the limiting hole 8 to limit the range of motion of the movable mounting plate 6, preventing the movable mounting plate 6 from affecting the normal operation of the anti-shake assembly due to excessive range of motion.

[0045] Example 2

[0046] This embodiment discloses a telescope equipped with the anti-shake assembly 2 described in Example 1. Specifically, the anti-shake assembly 2 is disposed inside the housing of the telescope, and the circuit board 5 of the anti-shake assembly 2 is fixed to the housing, so that the entire anti-shake assembly 2 is fixed inside the housing, while the movable mounting plate 6 is movable relative to the circuit board 5. Furthermore, the lens 7 of the anti-shake assembly 2 forms an optical path together with the objective lens 1, the erecting prism 3, and the eyepiece 4 of the telescope. That is, the objective lens 1, the anti-shake assembly 2, the erecting prism 3, and the eyepiece 4 are arranged in sequence inside the telescope, as shown in FIG. Figure 4 shown.

[0047] When the laser rangefinder vibrates, the gyroscope 21 detects this vibration, and the circuit board uses this information to determine the target amount of movement for the lens 7. Simultaneously, the Hall effect element detects the translational data of the movable mounting plate 6, i.e., the movement data of the lens 7. The circuit board 5 uses this data as feedback to execute a feedback control algorithm to determine the drive amount of the drive magnet. The drive coil then drives the corresponding drive magnet to translate, thereby moving the lens, offsetting the field of view shake caused by the vibration, and achieving image stabilization.

[0048] The telescope in this embodiment may be a monocular, binoculars, or a rangefinder telescope. When the telescope is a binocular, both lens barrels of the binocular can be installed with the anti-shake assembly 2 in the above embodiment.

[0049] The anti-shake component 2 of the present invention can also be applied to camera lenses.
