[0050] The patent website publication number CN106547065B discloses a movable lens adjustment mechanism, which uses a four-link flexible hinge transmission to fix the lens group on three evenly distributed flexible blocks, and drives the hinges on the flexible blocks to move through a motor to achieve the adjustment of the lens DzRxRy degrees of freedom. However, there are the following problems:

[0051] 1. The motor drive shaft and the flexible lever on the flexible block are in point contact, and there is wear during the movement, which reduces the transmission accuracy;

[0052] 2. The motor drive shaft and the flexible block are not fixedly connected, resulting in a low mechanism modality, poor stability of the lens, and a long movement time, which is not suitable for movable lenses with high dynamic response requirements.

[0053] After extensive and in-depth experiments, the inventor has designed a driving structure, a lens multi-directional adjustment device and a lens unidirectional adjustment device.

[0054] More specifically, the solution adopted by the present invention includes: by providing a locking portion at the end of the driving rod, the contact area with the driven part can be ensured, and the locking portion is pressed tightly against the driven part by a locking assembly to ensure the connection effect between the driving rod and the driven part and the high dynamic responsiveness of the driving mechanism. The pressing member can be pushed from the first position to the second position by a push rod, so that the pressing member is separated from the locking portion, and the disassembly operation of the driving part is more convenient.

[0055] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0056] like Figure 1-Figure 11 As shown, a driving structure includes:

[0057] A driving part 10, the driving part 10 comprises a driving member 11 and a driving rod 12, the driving rod 12 is mounted on the driving member 11, the driving member 11 is used to drive the driving rod 12 to move along the axial direction of the driving member 11, and a locking portion 14 is provided at one end of the driving rod 12 away from the driving member 11;

[0058] A driven member 3011, the driving rod 12 is in contact with the driven member 3011, and the driving rod 12 drives the driven member 3011 to move;

[0059] A locking assembly, the locking assembly comprising a holding member 21, a hinge and an elastic member 24, the holding member 21 being connected to the driven member 3011 via the hinge, the holding member 21 being rotatable from a first position to a second position relative to the driven member 3011, the two ends of the elastic member 24 being respectively connected to the driven member 3011 and the holding member 21, the elastic member 24 always pushes the holding member 21 to move from the second position to the first position, when the holding member 21 is in the first position, the holding member 21 presses the stopper 14 tightly against the driven member 3011, when the holding member 21 is in the second position, the holding member 21 is separated from the stopper 14;

[0060] The housing 50, the driven member 3011 is arranged inside the housing 50, and the driving member 11 is arranged outside the housing 50;

[0061] A push rod 40 passes through the housing 50 , and the push rod 40 can push the pressing member 21 from the first position to the second position.

[0062] When the drive structure needs to be installed: the push rod 40 is moved toward the inside of the shell 50, the push rod 40 presses the holding member 21 to rotate around the hinge from the first position to the second position, the drive part 10 is rotated a certain angle and then inserted into the shell 50, the drive rod 12 and the stopper 14 pass through the shell 50, the drive member 11 contacts the outer wall of the shell 50, and then the drive part 10 is rotated to the working state, the drive part 10 is fixed to the shell 50 by screws, and the push rod 40 is moved toward the outside of the shell 50, so that the push rod 40 is separated from the holding member 21, and under the action of the elastic member 24, the holding member 21 moves from the second position to the first position, at which time the holding member 21 presses the stopper 14 tightly against the driven member 3011, thereby realizing the connection between the drive rod 12 and the driven member 3011;

[0063] When the driving structure needs to be disassembled: move the push rod 40 toward the inside of the housing 50, the push rod 40 presses the holding part 21 to rotate around the hinge from the first position to the second position, the holding part 21 is separated from the locking part 14, loosen the screws fixing the driving part 10, rotate the driving part 10 by a certain angle, so that the locking part 14 avoids the holding part 21, and the driving part 10 can be taken out.

[0064] By providing a locking portion 14 at the end of the driving rod 12, the contact area with the driven part 3011 can be ensured. The locking portion 14 is pressed tightly against the driven part 3011 through the locking assembly to ensure the connection effect between the driving rod 12 and the driven part 3011 and the high dynamic responsiveness of the driving mechanism. The push rod 40 can push the holding member 21 from the first position to the second position, so that the holding member 21 is separated from the locking portion 14, and the disassembly operation of the driving part 10 is relatively convenient.

[0065] It should be noted that the push rod 40 may be a jackscrew, and the jackscrew is threadedly connected to the housing 50 .

[0066] It should be further explained that the locking portion 14 can be directly fixedly connected to the driving rod 12 (such as welding), and the locking portion 14 can also be detachably fixedly connected to the driving rod 12 (such as threaded connection).

[0067] It should also be noted that the elastic member 24 may be a spring or other elastic objects.

[0068] like Figure 1-Figure 11As shown, in some embodiments, the driving rod 12 is provided with a first groove 12a and a second groove 12b, and the first groove 12a and the second groove 12b are used to absorb the crosstalk force received by the driving rod 12 when the driving member 11 moves axially. When the driven member 3011 moves axially along the driving member 11, a movement crosstalk displacement in other directions will generally be generated. Since the driving rod 12 is fixed to the driven member 3011, the driving member 11 will be subjected to a crosstalk force perpendicular to the movement direction of the driving member 11, thereby reducing the performance of the driving member 11 and affecting its life. Therefore, the first groove 12a and the second groove 12b are provided on the driving rod 12 to absorb the crosstalk position and protect the driving member 11.

[0069] like Figure 1-Figure 11 As shown, in some embodiments, the holding member 21 includes a connecting plate 21a, a hinge ear 21b and a pressure block 21c, the connecting plate 21a is connected to the hinge through the hinge ear 21b, and the pressure block 21c is fixedly connected to the connecting plate 21a. When the holding member 21 is in the first position, the pressure block 21c presses the stopping portion 14 tightly against the driven member 3011. When the holding member 21 is in the second position, the pressure block 21c is separated from the stopping portion 14, the first side of the connecting plate 21a is connected to the elastic member 24, and the pressure block 21c is arranged on the second side of the connecting plate 21a. When the push rod 40 presses the first side of the connecting plate 21a, the connecting plate 21a rotates around the hinge ear 21b, and the pressure block 21c rotates with the connecting plate 21a, so that the position of the pressure block 21c can be adjusted so that the pressure block 21c is in contact with or separated from the stopping portion 14.

[0070] It should be noted that the pressing block 21c can be a small protruding block, and it is only necessary to ensure that when the holding member 21 is in the first position, the pressing block 21c can press the locking portion 14 tightly against the driven member 3011.

[0071] like Figure 1-Figure 11 As shown, in some embodiments, the locking portion 14 includes a plate body, and the plate body is installed on the driving rod 12. The plate body is provided with a notch, and the pressure block 21c can pass through the notch. By setting the locking portion 14 as a plate body, the contact area between the locking portion 14 and the driven member 3011 can be guaranteed. At the same time, by providing a notch on the plate body, the pressure block 21c can pass through the notch, which facilitates the installation and disassembly operations of the driving member 11.

[0072] like Figure 1-Figure 11As shown, in some embodiments, the hinged member includes a pin 22 and a first nut 23, the pin 22 passes through the hinged ear 21b and is rotatably connected to the driven member 3011, and the first nut 23 cooperates with the pin 22. By using the pin 22 to pass through the hinged ear 21b and the driven member 3011, and by cooperating with the nut and the pin 22, the connection between the holding member 21 and the driven member 3011 is completed, so that the holding member 21 can rotate relative to the driven member 3011, thereby allowing the holding member 21 to move between the first position and the second position.

[0073] like Figure 1-Figure 11 As shown, in some embodiments, the driving member 11 includes an electric push rod 40, and the output end of the electric push rod 40 passes through the housing 50 and is connected to the driving rod 12 through the second nut 13. By using the electric push rod 40 as the driving member 11, the convenience of driving is ensured.

[0074] like Figure 1-Figure 16 As shown, based on the same inventive concept, an embodiment of the present specification provides a multi-directional adjustment device for a lens, comprising a first lens 121, a plurality of groups of flexible block assemblies 130 and a driving structure as described in any one of the above, wherein the driven member 3011 comprises a first lens seat 120, the housing 50 comprises a first lens barrel 50a, the first lens 121 is mounted on the first lens seat 120, the flexible block assembly 130 is mounted on the first lens seat 120, the locking portion 14 is pressed tightly against the flexible block assembly 130 through the locking assembly, and the driving rod 12 drives the flexible block assembly 130 to move in the Z direction when moving axially, and the plurality of groups of flexible block assemblies 130 in the Z direction movement combination realize the movement of the first lens 121 in three degrees of freedom in the X direction, the Y direction and the Z direction.

[0075] The driving member 11 is driven to move axially by the driving member 11, and the locking portion 14 moves together with the driving member 11. Since the locking portion 14 is pressed against the flexible block assembly 130 by the locking assembly, the axial movement of the locking portion 14 drives the flexible block assembly 130 to move in the Z direction. The combination of the Z-direction movement of multiple flexible block assemblies 130 can realize the movement of the first lens 121 in three degrees of freedom: Dz, Rx, and Ry.

[0076] like Figure 1-Figure 16As shown, in some embodiments, the flexible block assembly 130 includes a flexible block 131, and the flexible block 131 is provided with four groups of grooves to form a four-bar structure. The four groups of links include a first link 1311, a second link 1312, a third link 1313, and a fourth link 1314. The first link 1311 is connected to the third link 1313 and the second link 1312 through a second hinge 131b and a third hinge 131c, respectively. The fourth link 1314 is connected to the third link 1313 and the first link 1311 through a first hinge 131a and a fourth hinge 131d, respectively. The locking portion 14 is in contact with the second connecting rod 1312, and a support block 1315 is provided on the fourth connecting rod 1314. The support block 1315 is connected to the fourth connecting rod 1314 through the fifth hinge 131e. When the driving rod 12 moves axially, it is converted into a rotational movement of the second connecting rod 1312 around the third hinge 131c, thereby driving the fourth connecting rod 1314 to move in the Z direction, and the support block 1315 moves with the fourth connecting rod 1314. Through the combined movement of the three evenly distributed support blocks 1315, the movement of the lens in the DzRxRy direction is realized.

[0077] It should be noted that in order to avoid the problem of the mechanism getting stuck due to inconsistent movement of the three flexible blocks 131, a fifth hinge 131e is set on the flexible block 131 and between the support block 1315. The fifth hinge 131e is used to absorb the stress caused by the inconsistent movement of the flexible block 131, thereby avoiding the mechanism getting stuck.

[0078] It should also be noted that, due to the fixed connection between the driving rod 12 and the flexible fastener, the modal of the movable mechanism is greatly improved, which can reach more than 200 Hz, thereby improving the stability of the mechanism and achieving the high dynamic stability requirements for adjusting the optical element.

[0079] like Figure 1-Figure 16 As shown, in some embodiments, the adjustment device also includes a centering spring 200, and the centering spring 200 includes an inner pressure ring 210 and an outer pressure ring 220. The inner pressure ring 210 is installed on the first lens seat 120, and the outer pressure ring 220 is installed on the lens barrel. The inner ring of the centering spring 200 is fixed to the first lens seat 120 by the inner pressure ring 210, and the outer ring of the centering spring 200 is fixed to the first lens barrel 50a by the outer pressure ring 220. The centering spring 200 can realize the centering of the first lens 121 to ensure that the center position of the first lens 121 remains unchanged during the movement of the first lens 121.

[0080] like Figure 1-Figure 11 and Figure 17-Figure 19As shown, based on the same inventive concept, an embodiment of the present specification provides a one-way adjustment device for a lens, comprising a second lens 300, a guide rail 320 and a driving structure as described in any one of the above items, wherein the driven member 3011 comprises a second lens seat 310, the housing 50 comprises a second lens barrel 330, the second lens 300 is mounted on the second lens seat 310, the guide rail 320 is arranged in the first lens barrel 50a, and the second lens seat 310 is mounted on the guide rail 320, and when the driving rod 12 moves axially, it drives the second lens seat 310 to slide along the guide rail 320, and the second lens 300 moves with the second lens seat 310 to adjust the second lens 300 in the X direction, and the second lens 300 is driven by the driving unit 10 to realize the movement of the second lens 300 in the X direction, and due to the fixed connection between the driving rod 12 and the second lens seat 310, the mode of the motion mechanism is greatly improved, and the high dynamic stability requirement of the optical element adjustment is realized.

[0081] The same or similar parts of the various embodiments in this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the method embodiment described later, since it corresponds to the system, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiment.

[0082] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
