Description

Technical Field

[0001] This invention belongs to the field of optical imaging equipment technology, and specifically relates to a direct-acting piezoelectric pressure-type gimbal. Background Technology

[0002] With the development of technology, many electronic devices today (such as smartphones or digital cameras) have the function of taking pictures or recording videos. The use of these electronic devices is becoming more and more common, and they are developing towards convenient and thinner designs to provide users with more choices.

[0003] Some electronic devices with photographic or video recording capabilities include a lens drive mechanism to move optical components such as a lens, thereby achieving autofocus and optical image stabilization (OIS). Light can pass through the optical components to form an image on the photosensitive element.

[0004] Existing lens drive devices typically include an OIS coil assembly to prevent lens shake, a magnet assembly, a zoom coil, and a carrier for mounting the lens. The OIS coil assembly usually has multiple OIS coils, and the magnet assembly has multiple magnets. Under the combined action of the OIS coils and their corresponding magnets, the carrier, along with the lens, moves along the X and Y axes. Under the combined action of the zoom coils and their corresponding magnets, the carrier, along with the lens, moves along the Z axis, thus achieving three-axis lens movement.

[0005] The driving method employs a combination of OIS coil and magnet groups, and an AF coil and magnet group. However, the generated magnetic field can interfere with other electronic components inside the phone. Furthermore, magnet groups typically have multiple magnets; if adjacent magnets are too close, their internal magnetic fields can interfere with each other, causing unexpected displacement or jitter, reducing the stability of autofocus control. Conversely, if adjacent magnets are too far apart, it hinders the miniaturization of electronic devices. Summary of the Invention

[0006] The present invention addresses the above-mentioned technical problems by providing a direct-acting piezoelectric pressure-type gimbal.

[0007] To address the aforementioned problems, according to one aspect of the present invention, a direct-acting piezoelectric gimbal is provided, comprising a housing, a base, a drive assembly, a frame, a motor carrier, and a built-in circuit. A hollow cavity is formed between the housing and the base. The motor carrier is disposed within the frame. The drive assembly and the frame are disposed within the hollow cavity. The drive assembly includes:

[0008] At least two sets of piezoelectric drive mechanisms are disposed on the base, located outside the frame and connected to the frame, and connected to the built-in circuit inside the base. When the at least two sets of piezoelectric drive mechanisms are energized, the frame and the motor carrier are driven to swing relative to the base in the X-axis or Y-axis direction.

[0009] This invention abandons the existing method of using OIS coil groups and magnet groups to drive the motor carrier. Instead, it adopts a piezoelectric drive mechanism. After the built-in circuit energizes the piezoelectric drive mechanism, it enables the frame and the motor carrier inside to swing. By swinging in different directions, it achieves anti-shake operation of the motor carrier in the X and Y axes. This drive method eliminates the need to consider the arrangement of magnets and magnetic field interference issues, and can be arranged in a miniaturized and lightweight manner according to the specifications of the motor carrier.

[0010] In addition, the present invention achieves a counter-pressure drive form by setting multiple piezoelectric drive mechanisms on the base. The multiple piezoelectric drive mechanisms can not only symmetrically squeeze the frame to perform reciprocating motion, but also limit and guide the frame and motor carrier, making the entire anti-shake operation process stable and reliable.

[0011] The piezoelectric drive mechanism consists of two sets, which are arranged opposite to each other on the outside of the frame.

[0012] The piezoelectric drive mechanism consists of three groups, with one group located on the perpendicular bisector of the line connecting the other two groups. The included angles between the three groups of piezoelectric drive mechanisms may be equal or unequal.

[0013] The piezoelectric drive mechanism consists of three or more groups, with several groups of the piezoelectric drive mechanism distributed around the outer periphery of the frame.

[0014] The piezoelectric drive mechanism includes:

[0015] A movable component, with springs connecting it to the frame on both sides, and wear-resistant parts provided on the outer side;

[0016] A piezoelectric mechanism includes a counterweight, a piezoelectric block, and a friction element. The counterweight is disposed on the base, and the piezoelectric block is disposed on the top of the counterweight. The piezoelectric block is connected to the built-in circuit, and the friction element is disposed on the top of the piezoelectric block. The friction element is in contact with the wear-resistant part.

[0017] When the piezoelectric block is energized, it deforms along the optical axis and pushes the friction element to move along the optical axis. The friction element and the wear-resistant element are connected by friction, which drives the movable element to move along the optical axis. The inner side of the movable element is squeezed by the friction. Under the action of the spring, the spring generates a reverse elastic force on the movable element, causing the movable element to press against the friction element, increasing the squeezing friction between the movable element and the friction element. When the piezoelectric mechanism moves, the squeezing friction guided by the friction element drives the movable element, the frame, and the motor carrier to move along the optical axis.

[0018] While one set of piezoelectric mechanisms moves upward along the optical axis, another set or more sets of piezoelectric mechanisms perform the opposite action, and under the action of the multiple sets of piezoelectric mechanisms, the frame swings.

[0019] The base is provided with a piezoelectric groove, and the counterweight is installed in the piezoelectric groove.

[0020] The frame has a piezoelectric mechanism mounting groove on its outer side, and the movable part is installed in the piezoelectric mechanism mounting groove. There is a clearance between the inner wall of the movable part and the inner wall of the piezoelectric mechanism mounting groove.

[0021] The springs on both sides of the movable component are either integral or separate structures;

[0022] The spring and the wear-resistant component are either integral or separate structures; or

[0023] The spring has a spring clearance through hole in the middle, and the wear-resistant part is located inside the spring clearance through hole.

[0024] A mounting base is provided on the base, and a position sensor is installed on the mounting base;

[0025] The frame is provided with a sensing magnet, which is arranged in correspondence with the position sensor;

[0026] The inductive magnet and the position sensor are both at least two in number and are arranged corresponding to the piezoelectric drive mechanism.

[0027] The motor carrier is an AF motor or a carrier used to mount an AF motor.

[0028] The bottom of the motor carrier is provided with a circuit board for supplying power to the AF motor, and the circuit board extends out of the base and the housing.

[0029] An FPC board clearance groove is provided on one side of the frame, an FPC board mounting groove is provided on the outer wall of the bottom end of the frame, and an FPC board limiting groove is provided on the base. The FPC board limiting groove is located outside the FPC board clearance groove.

[0030] The circuit board is an FPC board. After the FPC board extends out from the motor carrier, it passes through the FPC board clearance groove to the FPC board limiting groove. After being bent in the FPC board limiting groove, it passes through the FPC board mounting groove to the outside of the base.

[0031] Beneficial effects: The present invention has at least one or more of the following advantages:

[0032] 1. This invention employs multiple piezoelectric drive mechanisms to induce a swaying motion in the frame and motor carrier. The swaying motion in different directions achieves image stabilization along the X and Y axes of the motor carrier. Simultaneously, the AF motor's AF action enables lens zoom. Ultimately, this achieves OIS image stabilization and automatic zoom functionality. This invention eliminates the need to consider the placement of magnets and magnetic field interference issues, allowing for miniaturization and weight reduction based on the specifications of the motor carrier.

[0033] 2. Multiple piezoelectric drive mechanisms symmetrically or evenly distributed on the base work together to achieve multi-angle swinging motion of the frame and motor carrier. When the frame swings at multiple angles, the spring will twist due to the clearance design, while the moving parts will not twist in the direction of movement. This ensures that the contact area between the wear-resistant parts and the friction parts remains unchanged, thus ensuring that the friction effect between the friction parts and the moving parts does not change.

[0034] 3. The swaying amplitude of the frame can be monitored by using a position sensor in conjunction with a magnet. Attached Figure Description

[0043] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are only for illustrating the essential spirit of the technical solution of the present invention.

[0044] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0045] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0046] In the following description, in order to clearly demonstrate the structure and working method of the present invention, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0047] Reference Figures 1 to 8 This invention provides a direct-acting piezoelectric gimbal, comprising a housing 1, a base 2, a drive assembly, a frame 4, a motor carrier 5, and built-in circuitry. A hollow cavity exists between the housing 1 and the base 2, preferably formed by a snap-fit ​​connection. The motor carrier 5 is disposed within the frame 4. The drive assembly, frame 4, and motor carrier 5 are housed within the hollow cavity. A motor through-hole is axially connected along the vertical direction in the middle of the housing 1, base 2, drive assembly, frame 4, and motor carrier 5 to accommodate the motor.

[0048] The drive assembly includes at least two sets of piezoelectric drive mechanisms 3. Multiple sets of piezoelectric drive mechanisms 3 are mounted on the base 2 and located outside and connected to the frame 4. These multiple sets of piezoelectric drive mechanisms 3 mutually press and position the frame 4. The positions of the multiple sets of piezoelectric drive mechanisms 3 outside the frame 4 can be adjusted and set according to the number of piezoelectric drive mechanisms 3, as long as they can mutually press and position the frame 4 and drive it to swing. Each set of piezoelectric drive mechanisms 3 is connected to a built-in circuit within the base 2, which supplies power to the piezoelectric drive mechanism 3. When energized, the piezoelectric drive mechanism 3 can drive the frame 4 and its internal motor carrier 5 to move vertically. Through the movement of multiple sets of piezoelectric drive mechanisms 3 in different directions, the frame 4 and the motor carrier 5 can achieve a swinging motion relative to the base 2 in the X-axis or Y-axis direction. Here, the X-axis and Y-axis directions are perpendicular to the Z-axis (vertical direction).

[0049] This invention abandons the existing method of using OIS coil groups and magnet groups to drive the motor carrier 5. Instead, it adopts a piezoelectric drive mechanism 3. After the piezoelectric drive mechanism 3 is energized by the built-in circuit, it realizes the swinging motion of the frame 4 and the motor carrier 5 inside. The anti-shake operation of the motor carrier 5 in the X and Y axes is achieved by swinging motion in different directions. This drive method does not need to consider the arrangement of magnets and magnetic field interference problems, and can be miniaturized and lightweight according to the specifications of the motor carrier 5.

[0050] In addition, by setting multiple piezoelectric drive mechanisms 3 on the base 2, the present invention achieves a pressure-driven form. The multiple piezoelectric drive mechanisms 3 can not only symmetrically squeeze the positioning frame 4 to perform reciprocating motion, but also limit and guide the frame 4 and the motor carrier 5, making the entire anti-shake operation process stable and reliable.

[0051] Optionally, at least two sets of piezoelectric drive mechanisms 3 are distributed around the outer periphery of the frame 4. In some embodiments, multiple sets of piezoelectric drive mechanisms 3 are evenly distributed around the outer periphery of the frame 4.

[0052] Optionally, there are two sets of piezoelectric drive mechanisms 3, which are arranged opposite each other on the outside of the frame 4. For example, the two sets of piezoelectric drive mechanisms 3 are symmetrically arranged at the two end corners of the base 2, and the two sets of piezoelectric drive mechanisms 3 press against each other to position the frame 4.

[0053] Optional, refer to Figure 5 There are three sets of piezoelectric drive mechanisms 3, which are distributed on the outer periphery of the frame 4. The distribution strategy is as follows: one set of piezoelectric drive mechanisms 3 is located on the perpendicular bisector of the line connecting the other two sets of piezoelectric drive mechanisms 3. The included angles between the three sets of piezoelectric drive mechanisms 3 can be equal or unequal.

[0054] Optionally, there are three or more sets of piezoelectric drive mechanisms 3, with several sets of piezoelectric drive mechanisms 3 distributed around the outer periphery of the frame 4.

[0055] For example, if there are four sets of piezoelectric drive mechanisms 3, the four sets of piezoelectric drive mechanisms 3 are distributed around the perimeter of the frame 4. In this case, the outer wall of the frame 4 can be a quadrilateral or a multiple of four. If there are five sets of piezoelectric drive mechanisms 3, the five sets of piezoelectric drive mechanisms 3 can be distributed in a pentagonal pattern around the perimeter of the frame 4. In this case, the outer wall of the frame 4 can be an N-sided polygon or a multiple of N.

[0056] Optionally, multiple sets of piezoelectric drive mechanisms 3 adopt the same structure. Each set of piezoelectric drive mechanisms 3 includes a spring 31, a moving part 32, a wear-resistant part 33, and a piezoelectric mechanism including a counterweight 34, a piezoelectric block 35, and a friction part 36.

[0057] The two sides of the movable part 32 are connected to the frame 4 by springs 31, and a wear-resistant part 33 is provided on the outer side of the movable part 32. The counterweight 34 is provided on the base 2, and a piezoelectric block 35 is provided on the top of the counterweight 34. The piezoelectric block 35 is connected to the built-in circuit, and a friction element 36 is provided on the top of the piezoelectric block 35. The friction element 36 is in contact with the wear-resistant part 33.

[0058] After the piezoelectric block 35 is energized, it deforms in the vertical direction and pushes the friction element 36 to move in the vertical direction. The friction element 36 and the wear-resistant element 33 are connected by friction, which drives the movable element 32 to move in the vertical direction. The inner side of the movable element 32 is squeezed by friction. Under the action of the spring 31, the spring 31 generates a reverse elastic force on the movable element 32, causing the movable element 32 to be squeezed on the friction element 36, increasing the squeezing friction between the movable element 32 and the friction element 36. When the piezoelectric mechanism moves, the squeezing friction through the friction element 36 drives the movable element 32, the frame 4 and the motor carrier 5 to move in the vertical direction.

[0059] While one set of piezoelectric mechanisms is moving upwards, another set or more sets of piezoelectric mechanisms are moving in the opposite direction (downwards). Under the action of multiple sets of piezoelectric mechanisms, the frame 4 swings. By operating different piezoelectric mechanisms, the frame 4 can swing at multiple angles, thereby achieving anti-shake effects on the X and Y axes of the motor carrier 5.

[0060] Optionally, the outer side of the movable part 32 is provided with a V-groove, and the wear-resistant part 33 is a V-shaped part that fits into the V-groove. The wear-resistant part 33 is fitted and installed on the groove wall of the V-groove.

[0061] Optionally, the side of the friction element 36 that contacts the wear-resistant element 33 is an arc-shaped surface.

[0062] Optional, refer to Figures 2 to 4 The base 2 is provided with a piezoelectric groove 21, and the counterweight 34 is installed in the piezoelectric groove 21.

[0063] The number of piezoelectric grooves 21 is determined according to the number of piezoelectric drive mechanisms 3, with one piezoelectric groove 21 corresponding to one piezoelectric drive mechanism 3.

[0064] Optionally, the base 2 is provided with a mounting protrusion, and the mounting protrusion is provided with a piezoelectric groove 21.

[0065] Optional, refer to Figures 2 to 4 The frame 4 has a piezoelectric mechanism mounting groove 41 on its outer side. The movable part 32 is installed in the piezoelectric mechanism mounting groove 41. There is a clearance 6 between the inner wall of the movable part 32 and the inner wall of the piezoelectric mechanism mounting groove 41.

[0066] When the frame 4 swings at multiple angles, the spring 31 will twist due to the design of the clearance 6, while the moving part 32 will not twist in the direction of movement. This ensures that the contact area between the wear-resistant part 33 and the friction part 36 remains unchanged, thus ensuring that the friction effect between the friction part 36 and the moving part 32 does not change.

[0067] Optionally, the springs 31 on both sides of the movable part 32 can be an integral or separate structure.

[0068] like Figure 4 The spring 31 shown is a split structure, that is, the two sides of the movable part 32 are respectively connected to the inner frame 4 by two independent springs 31.

[0069] In some embodiments, two separate reeds 31 are connected to form an integral structure.

[0070] Optionally, the spring 31 and the wear-resistant part 33 can be integrated or separate structures.

[0071] In some embodiments, in the two springs 31 of the split structure, either spring 31 and its inner wear-resistant part 33 can be designed independently or integrally connected.

[0072] In some embodiments, the spring 31 with its integral structure and the wear-resistant part 33 on its inner side can be designed independently or can be designed to be connected as a whole.

[0073] Optionally, the spring 31 has a spring clearance through hole in the middle, and the wear-resistant part 33 is located inside the spring clearance through hole. The spring clearance through hole is designed so that the friction part 36 can pass through the spring clearance through hole and contact the wear-resistant part 33 inside it.

[0074] In some embodiments, refer to Figures 2 to 7The two spring sheets 31 of the split structure have a preset distance between them to form a through hole for the spring sheets to avoid each other.

[0075] Optionally, the single independent spring 31 includes two spring connectors and several bent spring wires, with the spring wires connected between the two spring connectors. One spring connector is connected to the frame 4, and the other spring connector is connected to the movable part 32, which is suspended in the piezoelectric mechanism mounting groove 41.

[0076] Optionally, both spring connectors are provided with spring connection holes, and the connection with the frame 4 or the movable part 32 is achieved through the spring connection holes and the matching fasteners.

[0077] Optional, refer to Figures 2 to 4 The base 2 is provided with a mounting base 22, and a position sensor 71 is mounted on the mounting base 22. A sensing magnet 72 is provided on the frame 4, and the sensing magnet 72 is set in correspondence with the position sensor 71 to monitor the sway amplitude of the frame 4.

[0078] There are at least two induction magnets 72 and position sensors 71, and they are arranged corresponding to the piezoelectric drive mechanism 3. That is, the number of mounting bases 22, the number of position sensors 71, and the number of induction magnets 72 are the same as the number of piezoelectric drive mechanisms 3.

[0079] Optionally, the mounting base 22 is located on the side of the corresponding set of piezoelectric drive mechanisms 3, and preferably the mounting base 22 is located on the side of the corresponding piezoelectric groove 21.

For example, one position sensor 71 is located on the perpendicular bisector of the line connecting the other two position sensors 71, and the included angles between the three position sensors can be equal or unequal.

[0081] Optionally, the mounting base 22 is provided with a sensor groove, and the position sensor 71 is installed in the sensor groove.

[0082] Optionally, the motor carrier 5 can be an AF motor itself, or it can be a carrier for mounting an AF motor. The zoom effect of the lens is achieved through the AF action of the AF motor.

[0083] Optionally, the bottom of the motor carrier 5 is provided with a circuit board 51 for powering the AF motor. The circuit board 51 extends out of the base 2 and the housing 1 to enable communication with external circuits.

[0084] Optional, refer to Figure 3 and Figure 4 An FPC board clearance groove 42 is provided on one side of frame 4. (See reference...) Figure 8An FPC board mounting groove 43 is provided on the outer wall of the bottom end of frame 4. (See reference...) Figures 2 to 6 The base 2 is provided with an FPC board limiting groove 23, which is located outside the FPC board clearance groove 42.

[0085] Reference Figures 3 to 7 The circuit board 51 is an FPC board. After the FPC board extends out from the motor carrier 5, it passes through the FPC board clearance groove 42 to the FPC board limiting groove 23. After bending in the FPC board limiting groove 23, it passes through the FPC board mounting groove 43 to the outside of the base 2.

[0086] Optionally, the FPC board mounting slot 43 can be a straight slot or a bent slot, and can be designed according to the specific structure of the frame 4, base 2, or shell 1. For example, Figure 8 As shown, the FPC board mounting slot 43 is a V-shaped bent slot.
