[0037] Embodiment 1

[0038] As Figure 3 , 4As shown, the embodiment discloses a lens anti-shake assembly, which comprises a limiting cover and a lens anti-shake structure 40 installed in the limiting cover.

[0039] The limiting cover comprises a bottom cover 20 and an end cover 10 connected to the bottom cover 20, and the bottom cover 20 and the end cover 10 are both provided with through holes corresponding to the positions of the anti-shake lenses 47 in the lens anti-shake structure 40, so that the bottom cover 20 and the end cover 10 will not block the anti-shake lenses 47 of the lens anti-shake structure 40.

[0040] Specifically, the bottom cover 20 is circumferentially provided with a plurality of support columns 21, and the end cover 10 is installed on the support columns 21 by screws, so that the end cover 10 can be connected to the bottom cover 20 through the support columns 21, and the lens anti-shake structure 40 is installed in an installation area jointly enclosed by all the support columns 21, as shown. Figure 1 In this way, the entire lens anti-shake structure 40 is protected inside the limiting cover.

[0041] In addition, the end surface of the bottom cover 20 is provided with a protrusion 22 which can be clamped in a clamping groove in the telescope shell, so that the lens anti-shake structure 40 can be stably installed in the telescope, and the anti-shake precision is ensured.

[0042] As shown, Figure 4 The lens anti-shake structure 40 comprises a main control circuit board 45 and a motion assembly 41. The motion assembly 41 is installed with anti-shake lenses 47, and the main control circuit board 45 is provided with through holes corresponding to the anti-shake lenses 47. During installation, the main control circuit board 45 is fixedly installed in the bottom cover 20, and the motion assembly 41 is connected to the bottom cover 20 through a plurality of tension springs 30. Specifically, a plurality of tension spring avoiding grooves can be formed on the main control circuit board 45, one end of the tension spring 30 is connected to the bottom cover 20, and the other end is connected to the motion assembly 41 after passing through the tension spring avoiding groove. Through the support of the tension spring 30, the motion assembly 41 is separated from the main control circuit board 45, and due to the flexible characteristics of the tension spring 30, the motion assembly 41 can move relative to the main control circuit board 45 under external force.

[0043] The motion assembly 41 takes a movable mounting plate as a carrier, which is provided with two orthogonally distributed driving magnetic steels 42 and two orthogonally distributed sensing magnetic steels 46. The main control circuit board 45 is provided with a gyroscope 48, two driving coils 49 and two Hall sensors 44. The positions of the two driving coils 49 correspond to the two driving magnetic steels 42 one by one, so as to drive the motion assembly 41 to move up and down and left and right relative to the main control circuit board 45. The positions of the two Hall sensors 44 correspond to the two sensing magnetic steels 46 one by one.

[0044] By the above structure, one drive coil 49 and its opposite drive magnetic steel 42 form a drive structure in one direction, such as a drive structure in the left-right direction, which can drive the movement assembly 41 to move in the left-right direction. Another drive coil 49 and its opposite drive magnetic steel 42 form a drive structure in another direction, such as a drive structure in the up-down direction, which can drive the movement assembly 41 to move in the up-down direction. Two Hall sensors 44 are respectively used to detect the movement information of the two sensing magnetic steels 46, when the movement assembly 41 moves, the two sensing magnetic steels 46 on it also move, and the two Hall sensors 44 respectively detect the movement information of the movement assembly 41 in the left-right direction and the up-down direction, and then obtain the movement information of the anti-shake lens 47.

[0045] The main control circuit board 45 can obtain the detection information of the Hall sensor 44 and the gyroscope 48, and control the work of the two drive coils 49 through the obtained information, and then control the movement of the movement assembly 41.

[0046] In addition, at least three balls 43 are installed on the movement assembly 41, and the balls 43 at least partially protrude from the movement assembly 41, so that the movement assembly 41 is isolated from the main control circuit board 45 through the balls 43. The rolling characteristics of the balls 43 can make the movement assembly 41 move more smoothly.

[0047] The lens anti-shake assembly of the embodiment sets the lens anti-shake structure 40 in the limiting cover, and the movement assembly 41 is limited and protected by the support column 21 of the limiting cover. Compared with the limiting method of using limiting screws in the traditional way, the movement assembly will not be deformed, and the optical performance is guaranteed.

[0048] Embodiment 2

[0049] As shown in Figure 5 The embodiment discloses an anti-shake telescope, which comprises a telescope shell 60, an objective lens 70 installed in the telescope shell 60, a lens anti-shake assembly 50 in the embodiment 1, a prism 110, an ocular lens 120, a telescope circuit board 90 and a battery 130. Among them, the objective lens 70, the lens anti-shake assembly 50, the prism 110 and the ocular lens 120 are distributed in sequence from the front end to the rear end of the telescope, so that the objective lens 70, the anti-shake lens 47 of the lens anti-shake assembly 50, the prism 110 and the ocular lens 120 together form an optical path. The main control circuit board 45 of the lens anti-shake assembly 50 and the battery 130 are electrically connected with the telescope circuit board 90.

[0050] In particular, the battery 130 can be a rechargeable battery, and the telescope circuit board 90 is provided with a charging connector 80 extending to the outside of the telescope housing 60 to facilitate charging of the battery. Of course, the battery 130 can also be a replaceable cylindrical battery, in which case the charging connector 80 can be omitted. In addition, the telescope circuit board 90 is also provided with a switch 100 extending to the outside of the telescope housing 60 to facilitate control of the entire device.

[0051] The telescope housing 60 is provided with a clamping groove, and when installed, the protrusion 22 on the lens anti-shake assembly 50 is clamped into the clamping groove, so that the lens anti-shake assembly 50 can be better fixed in the telescope housing 60, preventing the lens anti-shake assembly 50 from being tilted and ensuring the anti-shake precision of the anti-shake telescope.

[0052] Since the lens anti-shake structure 40 is protected in the limiting cover, when the lens anti-shake assembly 50 is installed from the front end of the telescope housing 60, the installation tool can be clamped on the limiting cover, avoiding direct clamping of the tool on the moving assembly 41 and causing damage to the anti-shake lens 47 on the moving assembly 41.

[0053] During use of the anti-shake telescope, when shaking occurs, the gyroscope 48 detects the shaking information, and the main control circuit board 45 obtains the target amount of movement of the anti-shake lens 47 according to the shaking information. At the same time, the Hall sensor detects the translation data of the moving assembly 41, i.e. the movement data of the anti-shake lens 47, and the main control circuit board 45 obtains the driving amount of the two driving magnetic steels 42 through feedback control algorithm with the data as feedback, and then drives the corresponding driving magnetic steel 42 to translate through the two driving coils 49, so as to move the anti-shake lens 47, offset the shaking caused by the field of view shaking, and realize the image stabilization function. In particular, the anti-shake telescope can be a Paul prism type or a roof prism type telescope.

[0054] It should be noted that all the features disclosed in the specification, or the steps in all the methods or processes disclosed, can be combined in any manner, except for the mutually exclusive features and / or steps.

[0055] In addition, the above specific embodiments are exemplary, and those skilled in the art can think of various solutions under the inspiration of the disclosure of the present application, and these solutions also belong to the disclosed scope of the present application and fall within the protection scope of the present application. Those skilled in the art should understand that the specification and drawings of the present application are illustrative and do not constitute a limitation on the claims.
