Description

Technical Field

[0001] This invention relates to the field of camera equipment technology, and in particular to a miniature image stabilization gimbal. Background Technology

[0002] In recent years, small mobile devices with fixed-focus wide-angle (over 80-degree field of view) shooting capabilities have become increasingly popular, and their applications are constantly expanding, including smart glasses, tablet computers, and drones. When taking photos and videos, these devices are susceptible to external vibrations that can cause blurring or shakiness, affecting the quality of the images and videos. This problem is exacerbated by more intense vibrations or in low light conditions.

[0003] To address these issues, numerous image stabilization technologies have emerged on the market, with miniature gimbal stabilization proving particularly effective. Miniature gimbal stabilization works by moving the entire camera module, including the lenses and image sensor, to achieve image stabilization. Typically, actuator components, such as shape memory alloy wires, are directly added to the side of the camera module. These wires retract when energized, causing the camera module to move.

[0004] Therefore, the existing structure of miniature image stabilization gimbals requires that the manufacturing and installation of these gimbals be done on the side. Side mounting necessitates machining each actuator component on the camera module on its side, which is slow, has low precision, and is difficult to control. Consequently, the production speed of existing miniature image stabilization gimbals is slow, and the low precision affects their stabilization performance, making them unsuitable for use. Summary of the Invention

The second plate is located on the side of the first plate and fixedly disposed on the base, with one end connected to the base and the other end bent to form a second wire clamp. The first shape memory alloy wire connects the first wire clamp and the second wire clamp. When the first shape memory alloy wire is energized, it contracts to drive the rotating frame to rotate the camera module relative to the base.

[0035] The following is for reference. Figures 1 to 8 To describe the miniature image stabilization gimbal according to embodiments of the present invention.

[0036] According to an embodiment of the present invention, a miniature image stabilization gimbal includes a base 100, a camera module 200, a rotating frame 300, a first plate 320, a second plate 110, and a first shape memory alloy wire 410. The camera module 200 is used to capture images. The rotating frame 300 is connected to the camera module 200, and a first rotating part 310 is provided on the rotating frame 300. The first rotating part 310 is rotatably connected to the base 100. The first plate 320 is disposed on the first rotating part 310. One end of the 20 is connected to the first rotating part 310, and the other end is bent to form the first wire clamp 321; the second plate 110 is located on the side of the first plate 320 and is fixedly mounted on the base 100. One end of the second plate 110 is connected to the base 100, and the other end is bent to form the second wire clamp 111; the first memory alloy wire 410 connects the first wire clamp 321 and the second wire clamp 111. When the first memory alloy wire 410 is energized, it contracts and drives the rotating frame 300 to rotate the camera module 200 relative to the base 100.

[0037] For example Figure 2 , Figure 4 and Figure 5As shown, the camera module 200 is connected to the rotating frame 300. The rotating frame 300 is rotatably connected to the base 100 via a first rotating part 310. A first plate 320 is disposed on the first rotating part 310, with one end connected to the first rotating part 310 and the other end bent to form a first wire clamp 321. A second plate 110 is disposed on the side of the first plate 320. It can be disposed on only one side of the first plate 320 or on both sides of the first plate 320. The second plate 110 is fixedly disposed on the base 100, with one end connected to the base 100 and the other end bent to form a second wire clamp 111. A first shape memory alloy wire 410 connects the first wire clamp 321 and the second wire clamp 111. Because the second wire clamp 111 is fixedly mounted on the base 100, its position remains relatively stationary. The first wire clamp 321 is mounted on the first rotating part 310. When the first shape memory alloy wire 410 is energized and retracts, the first shape memory alloy wire 410 pulls the first rotating part 310 to rotate through the first wire clamp 321. The rotation of the first rotating part 310 causes the rotating frame 300 to rotate relative to the base 100. The camera module 200 is connected to the rotating frame 300, and thus rotates relative to the base 100 along with the rotating frame 300.

[0038] The connection point between the first shape memory alloy wire 410 and the first clamp 321 can be in the middle, meaning both ends of the first shape memory alloy wire 410 are connected to the second clamp 111, and the middle is connected to the second clamp 111. With this configuration, when the camera module 200 needs to rotate relative to the base 100, voltage can be applied to the first clamp 321 and the second clamp 111 located on one side of the first clamp 321, while no voltage or an opposite voltage is applied to the other side of the second clamp 111. This energizes and contracts the first shape memory alloy wire 410, driving the rotating frame 300 to rotate relative to the base 100. Alternatively, the first shape memory alloy wire 410 can be connected at one end to the first clamp 321 and at the other end to the second clamp 111. By using multiple first shape memory alloy wires 410, the first shape memory alloy wires 410 can drive the rotating frame 300 to rotate relative to the base 100 in two directions.

[0039] When the first shape memory alloy wire 410 is energized and retracts, the camera module 200 rotates relative to the base 100, thereby achieving lens stabilization. Simultaneously, a first plate 320 is mounted on the first rotating part 310, and a second plate 110 is mounted on the second rotating part 610. One end of each plate is bent to form a first clamp 321 and a second clamp 111, which clamp the first shape memory alloy wire 410. During the installation of the miniature image stabilization gimbal, the first shape memory alloy wire 410 can be first fixed to the first clamp 321 and the second clamp 111, and then the first plate 320 and the second plate 110 can be installed vertically on the top or bottom wall of the base 100 and the rotating frame 300. It's important to understand that the first plate 320 and the second plate 110 can be manufactured as a single piece, allowing all the first plates 320 and 110 on each side to be placed in place at once. Then, the entire first plate 320 and second plate 110 are cut into their original forms. This design allows for the installation of all components of the miniature image stabilization gimbal in a straight-up-down manner, eliminating the need for separate installation on each side of the camera module 200, thus accelerating installation speed and improving accuracy.

[0040] In some specific embodiments of the present invention, a first ball bearing 510 is further included. A first arc-shaped notch 311 adapted to the first ball bearing 510 is provided on the first rotating part 310, and a first groove 120 adapted to the first ball bearing 510 is provided on the base 100. The first arc-shaped notch 311 and the first groove 120 surround the first ball bearing 510, and the rotating frame 300 is rotatably connected to the base 100 through the first ball bearing 510.

[0041] For example Figure 4 , Figure 5 and Figure 7 As shown, the miniature image stabilization gimbal also includes a first ball bearing 510. The first rotating part 310 has a first arc-shaped notch 311 adapted to the first ball bearing 510, and the base 100 has a first groove 120 adapted to the first ball bearing 510. The first arc-shaped notch 311 and the first groove 120 surround the first ball bearing 510, so that the rotating frame 300 is rotatably connected to the base 100 through the first ball bearing 510.

[0042] The first arc-shaped notch 311 and the first groove 120 enclose the first ball bearing 510. When the first shape memory alloy wire 410 drives the rotating frame 300 to rotate, the first rotating part 310 rotates relative to the base 100 through the first ball bearing 510, thereby adjusting the position of the camera module 200 to achieve image stabilization. This design also facilitates the installation of the miniature image stabilization gimbal. The first groove 120 and the first arc-shaped notch 311 on the base 100 and the first rotating part 310 facilitate operation and the installation of the first ball bearing 510. Furthermore, a baffle 700 can be provided at the top of the first arc-shaped notch 311 and the first groove 120 to prevent the first ball bearing 510 from sliding out of the first groove 120 and the first arc-shaped notch 311.

[0043] In some specific embodiments of the present invention, a first plate 320 is provided on both the top and bottom walls of the first rotating part 310.

[0044] For example Figure 3 and Figure 5 As shown, a first plate 320 is provided on both the top and bottom walls of the first rotating part 310. A second plate 110 is provided on both sides of the first plate 320. Two second plates 110 are provided on the same side of the base 100. One end of the two second plates 110 is overlapped and fixedly connected to the base 100, while the other ends are folded upwards to form a second wire clamp 111 and downwards respectively. Two first shape memory alloy wires 410 are provided. One first shape memory alloy wire 410 is connected to the first wire clamp 321 and the second wire clamp 111 located above the first rotating part 310, and the other wire is connected to the first wire clamp 321 and the second wire clamp 111 located below the first rotating part 310. When the camera module 200 needs to rotate relative to the base 100 to achieve image stabilization, the first shape memory alloy wire 410 located on the upper left or right side of the first rotating part 310 is energized and retracts, cooperating with the energized and retracted first shape memory alloy wire 410 located on the opposite side below the first rotating part 310. The resulting torque drives the rotating frame 300 to rotate relative to the base 100, thereby achieving the image stabilization effect. This configuration allows the first shape memory alloy wire 410 to more easily drive the rotating frame 300 to rotate relative to the base 100.

[0045] In some specific embodiments of the present invention, a support frame 600 is also included. The support frame 600 is connected to the camera module 200 and is rotatably connected to the rotating frame 300. The camera module 200 is rotatably connected to the rotating frame 300 through the support frame 600.

[0046] For example Figure 2 and Figure 4As shown, the miniature image stabilization gimbal also includes a support frame 600, which is connected to the camera module 200 and rotatably connected to a rotating frame 300. The camera module 200 is rotatably connected to the rotating frame 300 via the support frame 600. By setting the support frame 600 rotatably connected to the rotating frame 300, the camera module 200 can rotate relative to the rotating frame 300, and the rotating frame 300 can rotate relative to the base 100. When the rotation axis of the support frame 600 relative to the rotating frame 300 does not coincide with the rotation axis of the rotating frame 300 relative to the base 100, the camera module 200 can rotate in more directions. Furthermore, when the rotation axis of the support frame 600 relative to the rotating frame 300 and the rotation axis of the rotating frame 300 relative to the base 100 are perpendicular to each other, it is even more beneficial for the camera module 200 to rotate in multiple directions relative to the base 100.

[0047] In some specific embodiments of the present invention, a third plate 620, a fourth plate 330, and a second shape memory alloy wire 420 are also included. A second rotating part 610 is provided on the support frame 600 and is rotatably connected to the rotating frame 300. The third plate 620 is disposed on the second rotating part 610, with one end connected to the second rotating part 610 and the other end bent to form a third wire clamp 621. The fourth plate 330 is located on the side of the third plate 620 and is fixedly disposed on the rotating frame 300, with one end connected to the rotating frame 300 and the other end bent to form a fourth wire clamp 331. The second shape memory alloy wire 420 connects the third wire clamp 621 and the fourth wire clamp 331. When the second shape memory alloy wire 420 is energized, it contracts and drives the support frame 600 to rotate the camera module 200 relative to the rotating frame 300.

[0048] For example Figure 2 , Figure 3 and Figure 5As shown, the miniature image stabilization gimbal also includes a third plate 620, a fourth plate 330, and a second shape memory alloy wire 420. A second rotating part 610 is provided on the support frame 600, and the support frame 600 is connected to the rotating frame 300 through the second rotating part 610. The third plate 620 is disposed on the second rotating part 610, with one end connected to the second rotating part 610 and the other end bent to form a third wire clamp 621. The fourth plate 330 is located on the side of the third plate 620, and can be disposed on both sides of the third plate 620 or only on one side. One end of the fourth plate 330 is connected to the rotating frame 300, and the other end is bent to form a fourth wire clamp 331. The second shape memory alloy wire 420 connects to the third wire clamp 621 and the fourth wire clamp 331. The second shape memory alloy wire 420 is configured in the same way as the first shape memory alloy wire 410. When the second shape memory alloy wire 420 is energized and retracts, it drives the support frame 600 to rotate relative to the rotating frame 300, thereby causing the camera module 200 to rotate relative to the rotating frame 300. The third plate 620, the fourth plate 330, and the second shape memory alloy wire 420 are located on the side adjacent to the first plate 320, the second plate 110, and the first shape memory alloy wire 410, facilitating control of the direction of rotation of the support frame 600 relative to the rotating frame 300. Simultaneously, the arrangement of the third plate 620, the fourth plate 330, the third wire clamp 621, and the fourth wire clamp 331 also facilitates the installation and assembly of the miniature image stabilization gimbal. It is easy to understand that the first plate 320, the second plate 110, the third plate 620, and the fourth plate 330 can be directly molded from a single plate. During installation, the entire plate is installed on the top or bottom wall of the base and support frame, and then the entire plate is cut into the first plate 320, the second plate 110, the third plate 620, and the fourth plate 330. This installation method allows for the simultaneous processing of all actuator assemblies located on the four sides of the camera module 200, with high processing speed and high precision.

[0049] In some specific embodiments of the present invention, the miniature anti-shake gimbal further includes a second ball bearing 520, a second arc-shaped notch 611 adapted to the second ball bearing 520 is provided on the second rotating part 610, and a second groove 341 adapted to the second ball bearing 520 is provided on the rotating frame 300; the second arc-shaped notch 611 and the second groove 341 surround the second ball bearing 520, and the support frame 600 is rotatably connected to the rotating frame 300 through the second ball bearing 520.

[0050] For example Figure 4 , Figure 6 and Figure 8As shown, the second rotating part 610 has a second arc-shaped notch 611 that matches the second ball 520, and the rotating frame 300 has a second groove 341 that matches the second ball 520. The second arc-shaped notch 611 and the second groove 341 surround the second ball 520. The support frame 600 is rotatably connected to the rotating frame 300 through the second ball 520.

[0051] The second arc-shaped notch 611 and the second groove 341 enclose the second ball bearing 520. When the second shape memory alloy wire 420 drives the support frame 600 to rotate relative to the rotating frame 300, the second rotating part 610 rotates relative to the rotating frame 300 via the second ball bearing 520, thereby adjusting the position of the camera module 200 to achieve image stabilization. This design also facilitates the installation of the miniature image stabilization gimbal. The second groove 341 and the second arc-shaped notch 611 on the rotating frame 300 and the second rotating part 610 facilitate operation and the installation of the second ball bearing 520. Furthermore, a baffle 700 can be provided at the top of the second arc-shaped notch 611 and the second groove 341 to prevent the second ball bearing 520 from slipping out of the second groove 341 and the second arc-shaped notch 611.

[0052] In some specific embodiments of the present invention, a protrusion 340 is provided on the rotating frame 300, the position of the protrusion 340 corresponds to the position of the second rotating part 610, and the second groove 341 is provided on the protrusion 340.

[0053] For example Figure 6 and Figure 8 As shown, a protrusion 340 is provided on the rotating frame 300, and the position of the protrusion 340 corresponds to the position of the second rotating part 610. The second groove 341 is provided on the protrusion 340. This arrangement makes the placement of the second groove 341 more convenient. The protrusion 340 protrudes outward from the rotating frame 300, so that the second groove 341 has sufficient space to accommodate the second ball 520, allowing the second ball 520 to be more stably placed within the second groove 341.

[0054] In some specific embodiments of the present invention, the base 100 is provided with a clearance groove or clearance opening 130, the position of the clearance groove or clearance opening 130 corresponds to the position of the protrusion 340, and the protrusion 340 is located in the clearance groove or clearance opening 130.

[0055] For example Figure 2 and Figure 3As shown, the base 100 is provided with a clearance groove, the position of which corresponds to the position of the protrusion 340, allowing the protrusion 340 to be positioned within the clearance groove. The clearance opening 130 or clearance groove allows the protrusion 340 to move within the clearance opening 130 or clearance groove when the rotating frame 300 rotates relative to the support frame 600. The clearance opening 130 or clearance groove saves space in the miniature image stabilization gimbal, facilitating its miniaturization.

[0056] In some specific embodiments of the present invention, a third plate 620 is provided on both the top and bottom walls of the second rotating part 610.

[0057] For example Figure 3 and Figure 5 As shown, third plates 620 are provided on both the top and bottom walls of the second rotating part 610, allowing second shape memory alloy wires 420 to be positioned above and below the second rotating part 610. These second shape memory alloy wires 420 can be energized and contracted to generate a resultant torque that drives the support frame 600, causing the camera module 200 to rotate relative to the rotating frame 300. For example, energizing and contracting the second shape memory alloy wire 420 located on the upper right side and the lower left side of the second rotating part 610 can drive the support frame 600 to rotate clockwise relative to the rotating frame 300. Conversely, energizing and contracting the second shape memory alloy wire 420 located on the upper left side and the lower right side of the second rotating part 610 can drive the support frame 600 to rotate counterclockwise relative to the rotating frame 300.

[0058] In some specific embodiments of the present invention, a fourth plate 330 is provided on both the top and bottom walls of the rotating frame 300.

[0059] For example Figure 2 and Figure 5 As shown, a fourth plate 330 is provided on both the top and bottom walls of the rotating frame 300, and the fourth plate 330 is provided on both sides of the third plate 620.

[0060] The fourth plate 330 is disposed on the top and bottom walls of the rotating frame 300, with one end connected to the rotating frame 300 and the other end bent to form the fourth wire clamp 331. The third plate 620 is disposed on the top and bottom walls of the second rotating part 610, and the fourth plate 330 is disposed on the top and bottom of both sides of the third plate 620, so that two second shape memory alloy wires 420 can be disposed, one located above the second rotating part 610 and connected to the third wire clamp 621 and the fourth wire clamp 331 located above the rotating frame 300, and the other located below the second rotating part 610 and connected to the third wire clamp 621 and the fourth wire clamp 331 located below the rotating frame 300.

[0061] The following is for reference. Figures 1 to 8 A miniature image stabilization gimbal according to an embodiment of the present invention is described in detail with reference to a specific and complete example. It is to be understood that the following description is merely illustrative and not intended to limit the specific scope of the invention.

[0062] For example Figure 1 and Figure 2 As shown, the housing 800 of the miniature image stabilization gimbal has a base 100, a rotating frame 300, a support frame 600 and a camera module 200 inside. The camera module 200 is used to capture images. The support frame 600 is connected to the camera module 200, the support frame 600 is rotatably connected to the rotating frame 300, and the rotating frame 300 is rotatably connected to the base 100.

[0063] A first rotating part 310 is provided on the rotating frame 300, and the first rotating part 310 is rotatably connected to the base 100. A first plate 320 is provided on the top and bottom walls of the first rotating part 310, one end of the first plate 320 is connected to the first rotating part 310, and the other end is bent to form a first wire clamp 321. A second plate 110 is located on both sides of the first plate 320 and is fixedly provided on the base 100, one end of the second plate 110 is connected to the base 100, and the other end is bent to form a second wire clamp 111. A first arc-shaped notch 311 adapted to the first ball 510 is provided on the first rotating part 310, and a first groove 120 adapted to the first ball 510 is provided on the base 100. The first arc-shaped notch 311 and the first groove 120 surround the first ball 510, so that the rotating frame 300 is rotatably connected to the base 100 through the first ball 510, for example... Figure 5 and Figure 7 As shown, the first arc-shaped notch 311 and the first groove 120 enclose the first ball bearing 510. When the first shape memory alloy wire 410 drives the rotating frame 300 to rotate, the first rotating part 310 rotates relative to the base 100 through the first ball bearing 510. The first shape memory alloy wire 410 is connected to the first wire clamp 321 and the second wire clamp 111. When the first shape memory alloy wire 410 is energized and retracts, it drives the rotating frame 300 to rotate relative to the base 100.

[0064] The support frame 600 is connected to the camera module 200 and rotatably connected to the rotating frame 300. The camera module 200 is rotatably connected to the rotating frame 300 via the support frame 600. For example... Figure 4 , Figure 6 and Figure 8As shown, the second rotating part 610 has a second arc-shaped notch 611 adapted to the second ball 520, and the rotating frame 300 has a second groove 341 adapted to the second ball 520. The second arc-shaped notch 611 and the second groove 341 surround the second ball 520. The support frame 600 is rotatably connected to the rotating frame 300 through the second ball 520. The top of the first ball 510 and the second ball 520 are both provided with baffles 700 to prevent the first ball 510 and the second ball 520 from sliding out.

[0065] The second rotating part 610 has a third plate 620 on its top and bottom walls, and a fourth plate 330 on its top and bottom walls. One end of the fourth plate 330 is connected to the rotating frame 300, and the other end is bent to form a fourth wire clamp 331. A second shape memory alloy wire 420 connects the third wire clamp 621 and the fourth wire clamp 331. When the second shape memory alloy wire 420 is energized, it contracts, which can drive the support frame 600 to rotate relative to the rotating frame 300.

[0066] The rotating frame 300 is provided with a protrusion 340, the position of which corresponds to the position of the second rotating part 610, and a second groove 341 is provided on the protrusion 340. The base 100 is provided with a clearance groove, the position of which corresponds to the position of the protrusion 340, so that the protrusion 340 can be placed in the clearance groove.

[0067] This configuration allows the second shape memory alloy wire 420 to drive the support frame 600 to rotate relative to the rotating frame 300, and the first shape memory alloy wire 410 to drive the rotating frame 300 to rotate relative to the base 100, enabling the miniature image stabilization gimbal to provide good image stabilization for the camera module 200. Simultaneously, the arrangement of the first plate 320, the second plate 110, the third plate 620, and the fourth plate 330 allows for vertical installation of the miniature image stabilization gimbal, facilitating faster and more precise installation and enabling more accurate adjustment of the camera module 200.
