Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.

The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

The term "V-like" as used herein, broadly refers to a geometric shape having two symmetrical and inclined surfaces, and the geometric shape has only one centerline, and the centerline is typically at a location where the two inclined surfaces directly intersect or extend to intersect. Thus, a "V-like" shape may be understood to be a standard V-shape geometry, or other similar geometries, such as isosceles trapezoids, W-shapes, etc., that are similar to or derived from a V-shape, or geometries that are modified based on a V-shape geometry or other similar geometries, such as a concave recess or a structural protrusion formed along the centerline of a V-shaped member.

Currently, most of the optical adjustment frames in the prior art implement the translational motion of the optical element based on a cylindrical guide rail pair or a rectangular guide rail pair. The cylindrical guide rail pair has two degrees of freedom of linear motion and rotational motion, and when only one degree of freedom of linear motion is needed, the rotational degree of freedom is often restricted or limited, for example, a key groove is formed on the circumferential surface of the cylindrical guide rail or a plane is processed, or at least two cylindrical guide rails which are distributed in parallel are adopted; therefore, the structure complexity of the optical adjusting frame is increased, and the difficulty of accurate adjustment is increased due to large adjustment tolerance. Although the rectangular guide rail pair has a simple structure, wide guide rail surfaces and high bearing capacity, the existence of the plurality of guide rail surfaces enables the optical element to easily generate deflection angles due to deflection in the process of carrying out translation by the rectangular guide rail pair, thereby causing serious influence on the adjustment precision of the optical adjustment frame.

The optical adjusting frame provided by the application realizes the adjustment and control of the translation action of the optical element mainly based on the V-shaped guide rail pair, the V-shaped guide rail pair mainly comprises a V-shaped sliding groove and a V-shaped sliding block, and particularly has the structural characteristic that the V-shaped sliding block can only move relative to the V-shaped sliding groove along the central line of the V-shaped sliding groove by utilizing the matching relation between the V-shaped sliding groove and the V-shaped sliding block, can ensure that the optical element can always translate along the preset direction or track (namely, the extending direction of the central line of the V-shaped sliding chute or the extending direction of the central line of the V-shaped sliding block) under the action of the V-shaped guide rail pair without generating position deviation in other directions, thereby creating favorable conditions for improving the adjustment precision of the optical adjusting frame on the position or the orientation of the optical element; meanwhile, based on the shape matching relationship between the V-shaped sliding groove and the V-shaped sliding block, the adjusting tolerance of the optical adjusting frame can be effectively reduced, the adjusting difficulty of the position or the direction of the optical element can be reduced, and the adjusting accuracy can be improved. In addition, the characteristics that the V-shaped guide rail pair can automatically compensate and does not generate structural clearance under the action of vertical load are utilized, and the guiding precision of the optical adjusting frame to the optical element can be ensured, so that the optical element can be positioned at the optimal position or direction for realizing the functions of the optical system.

For clearly and clearly describing the structural layout and the functional coordination relationship among the components, please refer to fig. 1, fig. 6 and fig. 7, the present application defines a first direction, a second direction and a third direction, the first direction, the second direction and the third direction form a rectangular spatial coordinate system in a certain spatial environment, when the optical adjusting frame is located in the spatial environment, the defined directions can be used to distinguish the relationship of the position, the orientation, the motion and the like among the described objects, for example, when the first direction is an up-down direction, and the second direction is a left-right direction, the third direction is a front-back direction; meanwhile, the fourth direction is also defined in the present application, and may be any direction different from the first direction, the second direction, and the third direction, or may be one of the first direction, the second direction, and the third direction, so as to further express relationships such as positions, orientations, and motions between the described objects by using the fourth direction.

In one embodiment, referring to fig. 1 to 4 and fig. 6 and 7, the adjusting portion 10 includes a first adjusting member 11 and a second adjusting member 12; wherein, the first adjusting member 11 is used as a connecting carrier between the supporting portion 20 and the adjusting portion 10, and is provided with a first sliding slot a1 which is distributed in a straight line along the first direction and is similar to a V shape; accordingly, the supporting portion 20 is provided with a V-like first sliding block a2 extending linearly along the first direction, the V-like first sliding block a2 matches the V-like first sliding slot a1 in terms of cross-sectional shape, cross-sectional dimension, etc., and the V-like first sliding block a2 is embedded in the V-like first sliding slot a1 to establish a linear sliding connection relationship between the first adjusting member 11 and the supporting portion 20, or both, so that the supporting portion 20 can drive the optical element a to move or stay to a predetermined position along the first direction by driving the supporting portion 20 to perform a translational motion relative to the first adjusting member 11, thereby realizing a function of adjusting the position or orientation of the optical element a in one dimension. The second adjusting member 12 is used as a carrier for assembling the whole optical adjusting frame with other associated mechanisms, so as to fixedly mount the whole optical adjusting frame at a predetermined position associated with the optical system, such as locking on a carrying device of the optical system; the second adjusting piece 12 is provided with a V-like second sliding chute b1 which is linearly distributed along the second direction; accordingly, the first adjusting member 11 is provided with a V-like second sliding block b2 extending linearly along the second direction, the V-like second sliding block b2 matches the V-like second sliding slot b1 in terms of cross-sectional shape, cross-sectional size, etc., and the V-like second sliding block b2 is embedded in the V-like second sliding slot b1 to establish a linear sliding connection between the first adjusting member 11 and the second adjusting member 12, or by the cooperation of the two, so that the first adjusting member 11 (together with the support portion 20 and the optical element a) can be moved or stopped to a certain preset position along the second direction by driving the first adjusting member 11 to perform a translational motion relative to the second adjusting member 12, thereby realizing a function of adjusting the position or orientation of the optical element a in another dimension.

In another embodiment, the positions of the V-like first sliding groove a1 and the V-like first sliding block a2, the V-like second sliding groove b1 and the V-like second sliding block b2 can be exchanged; taking the V-like first slide groove a1 and the V-like first slide block a2 as examples, the V-like first slide groove a1 may be disposed on the supporting portion 20, and the V-like first slide block a2 may be disposed on the first adjusting member 11. In other embodiments, the second adjusting member 12 may be omitted, and the optical element a may be provided with a condition for changing the position or the orientation in only one dimension, specifically, the "V" -like first sliding groove a1 and the "V" -like first sliding block a2 may be distributed along the first direction or the second direction by selecting the arrangement direction of the first adjusting member 11, so as to finally change the position or the orientation of the optical element a along the first direction or the second direction, thereby enabling the optical adjustment frame to be applied to a scene requiring a single number of dimensions for the translational movement of the optical element a.

On one hand, based on the structure matching relationship between the V-like sliding groove and the V-like sliding block, because the V-like sliding groove is provided with two symmetrical and crossed inclined planes (the plane where the central line or the central line is located is the boundary line or the boundary plane of the two inclined planes), when the V-like sliding block is embedded into the V-like sliding groove, the two inclined planes can respectively form the restriction and the limitation on the V-like sliding block from the two symmetrical sides of the V-like sliding block, so that the V-like sliding block and the related parts thereof cannot deflect towards the two sides and can only move along the extending direction of the central line of the V-like sliding groove; therefore, when the part associated with the V-shaped sliding groove and the part associated with the V-shaped sliding block move relatively, the part only has the characteristic of one translational motion degree of freedom or translational motion in one dimension, so that the adjustment tolerance is effectively reduced, a condition is created for the accurate adjustment of the position or the orientation of the optical element A, the guiding precision of the optical adjustment frame is higher, and especially when the V-shaped sliding groove and the V-shaped sliding block are subjected to loads perpendicular to the V-shaped sliding groove and the V-shaped sliding block simultaneously (for example, when the parts associated with the V-shaped sliding groove and the V-shaped sliding block are locked in position), the automatic compensation of the gap between the V-shaped sliding groove and the V-shaped sliding block can be realized, so that the structural gap between the V-shaped sliding groove and the V-shaped sliding block is eliminated; compared with the existing optical adjusting frame, the structure is more compact and the guiding precision is higher. On the other hand, by using the matching relationship among the first adjusting member 11, the second adjusting member 12 and the supporting portion 20, the translational adjustment of the optical element a in multiple dimensions can be realized, and conditions are created for finally enabling the optical element a to be in an optimal position or orientation in the optical system or the optical path.

In one embodiment, the relative position between the first adjusting member 11 and the supporting portion 20 is fixed by a first locking member 30, and the first locking member 30 is a fitting having a threaded connection structure, such as a screw, a bolt, or other hardware fitting; for example, referring to fig. 1 to 5, the V-like first sliding groove a1 is disposed on the first adjusting member 11, and the V-like first sliding block a2 is disposed on the supporting portion 20, the V-like first sliding groove a1 is provided with a first limiting hole c1 distributed through the first adjusting member 11 along the third direction, a center line of the first limiting hole c1 is perpendicular to a center line of the V-like first sliding groove a1 (i.e., the first limiting hole c1 penetrates through the first adjusting member 11 via the center line of the V-like first sliding groove a 1), and the first limiting hole c1 is in a strip-shaped through hole structure in the first direction to adapt to the sliding stroke of the V-like first sliding block a2 in the first direction; the V-like first sliding block a2 is provided with first locking holes c2 for matching with the first limiting holes c1, the number of the first locking holes c2 is two or more, the first locking holes c2 are arranged on the V-like first sliding block a2 at intervals along a first direction, and the central line of the first locking holes a2 is vertically intersected with the central line of the V-like first sliding chute a1 at the same time (namely, the extending direction of the first locking holes a2 is a third direction); thus, after the first locking member 30 penetrates through the first limiting hole c1, one end of the first locking member 30 adjacent to the supporting portion 20 is screwed into the first locking hole c2, and one end of the first locking member away from the supporting portion 20 abuts against the first adjusting member 11, so that the first adjusting member 11 and the supporting portion 20 can be locked and fixed by screwing the first locking member 30, and the V-like first sliding block a2 is stably embedded in a certain preset position of the V-like first sliding slot a 1; after the locking relationship is released, the first limiting hole c1 is in the form of a strip-shaped through hole, and the supporting portion 20 can drive the optical element a to move to any position along the first direction under the matching of the V-like first sliding groove a1 and the V-like first sliding block a2, so as to adjust the position or orientation of the optical element a.

In another embodiment, the positions of the first limiting hole c1 and the first locking hole c2 can be changed, namely: a first locking hole c2 is provided in a member (e.g., the first adjusting piece 11) associated with the V-like first slide groove a1, and a first stopper hole c1 is provided in a member (e.g., the support portion 20) associated with the V-like first slide block a 2. In other embodiments, the relative position between the first adjusting member 11 and the supporting portion 20 may be fixed in other manners, so as to omit the first limiting hole c1 and the first locking hole c2, for example, a pressing piece is disposed at the side edge of the opening of the V-like first sliding groove a1, and the pressing piece is used to press the V-like first sliding block a2 against a predetermined position of the V-like first sliding groove a 1.

In the embodiment of the adjusting portion 10 having the second adjusting member 12, referring to fig. 1 to 5, the relative position between the first adjusting member 11 and the second adjusting member 12 is fixed, and the fixing manner between the first adjusting member 11 and the supporting portion 20 can also be referred to, for example, in the case that the "V" -like second sliding slot b1 is disposed on the second adjusting member 12, and the "V" -like second sliding block b2 is disposed on the first adjusting member 11, the first adjusting member 11 can be provided with the second limiting hole d1, the second limiting hole d1 penetrates the "V" -like second sliding block b2 along the first direction, and is in the structure of a strip-shaped through hole in the second direction, the second adjusting member 12 is provided with a plurality of second locking holes d2 which are arranged at intervals along the second direction and are distributed along the first direction to penetrate the "V" -like second sliding slot b1, so as to utilize the second limiting hole d1, the second locking holes d2 to cooperate with the second locking member 40 such as screws and screws, the locking and fixing of the relative position between the first adjusting piece 11 and the second adjusting piece 12 are realized; as for the specific locking principle, the position adjusting manner, and other fixing manners, the foregoing are already mentioned, and therefore, the detailed description thereof is omitted here.

In one embodiment, referring to fig. 7 in combination with fig. 1 to 6, the adjusting portion 10 further includes a third adjusting member 13, and the third adjusting member 13 is used as a carrier for assembling the whole optical adjusting frame and other associated mechanisms instead of the second adjusting member 12; the structure matching relationship between the third adjusting piece 13 and the second adjusting piece 12 can be selectively set by referring to the first adjusting piece 11 and the second adjusting piece 12 or the first adjusting piece 11 and the supporting part 20; such as: a third sliding groove e1 similar to a V shape and a corresponding third locking hole f2 extending along the third direction are arranged on the third adjusting piece 13, and a third sliding block e2 similar to the V-shaped third sliding groove e1 and a third limiting hole f1 matched with the third locking hole f3 are arranged on the second adjusting piece 12; therefore, the dimension of translational adjustment of the optical element A can be further increased through the additional third adjusting piece 13, so that the position or the orientation of the optical element A in the first direction, the second direction and the third direction can be adjusted with certain travel.

In one embodiment, referring to fig. 1 and 7, the supporting portion 20 is mainly composed of a supporting member 21, a supporting member 22 and a fixing member 23; the carrier 21 is mainly used for mounting and fixing the optical element a, for example, an arc-shaped notch g may be provided on the carrier 21, and the edge portion of the optical element a is fixed in the arc-shaped notch g by gluing, crimping, clamping and the like by using the shape matching relationship between the arc-shaped notch g and the optical element a such as an optical lens, so as to avoid interference to the main body portion of the optical element a to the maximum extent; the supporting member 22 is mainly used for structural engagement with the first adjusting member 11, so that the whole supporting portion 20 can perform translational sliding motion along a first direction relative to the first adjusting member 11 by driving the supporting member 22, for example, a V-like first sliding block a2 can be arranged on the supporting member 22; the fixing member 23 is mainly used for establishing a structural connection relationship and/or a motion relationship between the supporting member 21 and the supporting member 22, specifically, the fixing member 23 may be a rod-like structure such as a screw, so that a first end and a second end that are oppositely distributed may be formed along the extending direction thereof, one of the supporting member 21 and the supporting member 22 is fixedly connected to the first end of the fixing member 23, and the other one of the supporting member 21 and the supporting member 22 is rotatably connected to the second end of the fixing member 23, so that the supporting member 21 can drive the optical element a to rotate relative to the supporting member 22 around the extending direction of the fixing member 23, so as to impart a rotational degree of freedom to the optical element a, thereby being capable of adapting to the requirement of the optical system itself on the position or orientation of the optical element a, and realizing the adjustment of the parameter of the optical element a, such as the deflection angle. The extending direction of the fixing member 23 may be a first direction, a second direction, a third direction or any other direction; in this embodiment, the extending direction of the fixing member 23 is a third direction, and the fixing member 23 is rotatably connected to the carrier 21 in a threaded manner; in this way, by adjusting the length of the fixing member 23 extending into the supporting member 21, not only the rotation angle of the supporting member 21 can be adjusted and determined, but also the linear motion adjustment can be performed on the supporting member 21 and the optical element a carried by the supporting member 21 along the third direction, so as to achieve the effect similar to the translational motion that can be generated by the third adjusting member 13 and the second adjusting member 12 in the optical adjustment frame.
