[0063] 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.

[0064] 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.

[0065] 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.

[0066] In the following description, in order to clearly demonstrate the structure and working method of this utility model, 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.

[0067] Example 1:

[0068] Reference Figures 1 to 7 This embodiment provides an interlaced horizontal moving platform that can move in both the X-axis and Y-axis directions. When the interlaced horizontal moving platform is used in a lens driving device, the component to be moved is a carrier. As a carrier moving structure, the interlaced horizontal moving platform can realize the OIS image stabilization operation of the lens mounted on the carrier.

[0069] The staggered horizontal moving platform of this embodiment includes a base 10, a carrier 20, a movable frame 30, and a drive mechanism. The movable frame includes an X-axis movable frame 31 and a Y-axis movable frame 32, and the drive mechanism includes an X-axis drive mechanism 41 and a Y-axis drive mechanism 42.

[0070] Reference Figure 4 The bottom of the carrier 20 is provided with an X-axis contact slope 210 and a Y-axis contact slope 220. The number of X-axis contact slopes 210 and Y-axis contact slopes 220 can be set to one or more according to the actual situation. For example, two X-axis contact slopes 210 and two Y-axis contact slopes 220 are set, and the four contact slopes are distributed around the bottom of the carrier 20.

[0071] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7The X-axis movable frame 31 is provided with a Y-axis guide ramp 310, and the Y-axis movable frame 32 is provided with an X-axis guide ramp 320. When the carrier 20 is placed on the X-axis movable frame 31 and the Y-axis movable frame 32, the X-axis contact ramp 210 is placed on the X-axis guide ramp 320 and contacts the X-axis guide ramp 320. The Y-axis contact ramp 220 is placed on the Y-axis guide ramp 310 and contacts the Y-axis guide ramp 310. Through the contact between the guide ramp and the contact ramp, the carrier 20 will not rotate when moving in the X-axis and Y-axis directions, ensuring the accuracy of its movement.

[0072] In this embodiment, the number of X-axis contact slope 210, Y-axis contact slope 220, X-axis guide slope 320, and Y-axis guide slope 310 is not limited, and one or more can be set according to the actual situation.

[0073] Reference Figure 5 The X-axis movable frame 31 and the Y-axis movable frame 32 are staggered and stacked (also known as staggered arrangement). By staggering the X-axis movable frame 31 and the Y-axis movable frame 32, the Y-axis guide slope 310 inside the X-axis movable frame 31 and the X-axis guide slope 320 inside the Y-axis movable frame 32 are fully exposed to the bottom end of the carrier 20 and are in complete contact with the Y-axis contact slope 220 and the X-axis contact slope 210 at the bottom end of the carrier 20, so that the carrier 20 can be stably placed on the X-axis movable frame 31 and the Y-axis movable frame 32.

[0074] In this embodiment, the X-axis movable frame 31 and the Y-axis movable frame 32 can be frame-shaped structures or open frame structures. This embodiment does not limit the staggered stacking style between the X-axis movable frame 31 and the Y-axis movable frame 32; the staggered stacking in this embodiment includes, but is not limited to, the following: Figure 5-1 The six styles shown in (a) to (f) are as follows. After the X-axis movable frame 31 and the Y-axis movable frame 32 are staggered and stacked, they can form a frame-like structure that is approximately enclosed or partially enclosed. Of course, other structures are also possible, as long as the staggered stacking of the two can expose all the guide slopes so that the contact slopes on the carrier 20 can be placed, contacted, and can slide relative to each other on the corresponding guide slopes.

[0075] When the X-axis drive mechanism 41 moves the X-axis movable frame 31 relative to the base 10 in the X-axis direction, it in turn moves the carrier 20 along the X-axis guide slope 320 in the X-axis direction. Similarly, when the Y-axis drive mechanism 42 moves the Y-axis movable frame 32 relative to the base 10 in the Y-axis direction, it in turn moves the carrier 20 along the Y-axis guide slope 310 in the Y-axis direction. Through the drive of the X-axis drive mechanism 41 and the Y-axis drive mechanism 42, OIS image stabilization of the lens mounted on the carrier 20 is achieved.

[0076] In one embodiment, the length direction of the X-axis contact slope 210 and the length direction of the X-axis guide slope 320 are both X-axis directions, and the length direction of the Y-axis contact slope 220 and the length direction of the Y-axis guide slope 310 are both Y-axis directions.

[0077] In one embodiment, the X-axis guide ramp 320 and the Y-axis guide ramp 310 have the same structure, but their positions and length directions are different.

[0078] The X-axis guide ramp 320 and the Y-axis guide ramp 310 are at the same height relative to the base 10, so that after they support and contact the carrier 20, the carrier 20 can be placed horizontally.

[0079] In one embodiment, one of the X-axis movable frame 31 and the Y-axis movable frame 32 is provided with an installation step and the other is placed inside the installation step.

[0080] Reference Figure 6 An installation step 321 is provided on the Y-axis movable frame 32, and the X-axis movable frame 31 is disposed within the installation step 321 to reduce the height difference between the guide ramps on the X-axis movable frame 31 and the Y-axis movable frame 32. In this case, the Y-axis movable frame 32 can be a frame structure or an open frame structure, and the X-axis movable frame 31 is preferably an open frame structure, so that the X-axis movable frame 31 is better disposed within the installation step 321.

[0081] In one embodiment, in order to ensure stable contact between the contact slope at the bottom of the carrier 20 and the guide slope on the movable frame, the staggered horizontal moving platform further includes a pressing structure for pressing the carrier 20 onto the X-axis movable frame 31 and the Y-axis movable frame 32.

[0082] Reference Figure 1 and Figure 2 In this embodiment, the clamping structure adopts a spring sheet structure, specifically:

[0083] The clamping structure uses a first spring 51, which is connected to the carrier 20 and the base 10 respectively. The first spring 51 presses the carrier 20 onto the X-axis movable frame 31 and the Y-axis movable frame 32 and achieves the reset effect after movement in the X-axis and Y-axis directions.

[0084] The first spring 51 preferably adopts an L-shaped structure. The first spring 51 is horizontally arranged, and its two ends have carrier connecting parts that connect to the top surface of the carrier 20. The corner of the first spring 51 has a base connecting part that connects to the top surface of the base 10. The two carrier connecting parts are respectively connected to the base connecting parts by elastic spring wires.

[0085] In one embodiment, the movable frame is made of plastic, that is, the X-axis movable frame 31 and the Y-axis movable frame 32 are made of plastic, and the Y-axis guide ramp 310 and the X-axis guide ramp 320 are plastic ramps.

[0086] Of course, the movable frame can also be made of metal parts. That is to say, if the X-axis movable frame 31 and the Y-axis movable frame 32 are made of metal parts, then the Y-axis guide slope 310 and the X-axis guide slope 320 are metal slopes.

[0087] In one embodiment, the staggered horizontal moving platform further includes a friction reduction structure, which is used to reduce the frictional force between the X-axis contact inclined surface 210 and the X-axis guide inclined surface 320 during relative movement, and the friction reduction structure is also used to reduce the frictional force between the Y-axis contact inclined surface 220 and the Y-axis guide inclined surface 310 during relative movement.

[0088] In one embodiment, the X-axis drive mechanism 41 and the Y-axis drive mechanism 42 are respectively employed as one of a piezoelectric mechanism, an electromagnetic drive mechanism, and a shape memory alloy drive mechanism. The X-axis drive mechanism 41 and the Y-axis drive mechanism 42 may also employ other drive mechanisms found in the prior art.

[0089] Both the X-axis drive mechanism 41 and the Y-axis drive mechanism 42 preferably employ piezoelectric mechanisms.

[0090] In one embodiment, the piezoelectric mechanism used in the X-axis drive mechanism 41 and the Y-axis drive mechanism 42 is a first piezoelectric mechanism.

[0091] Taking the X-axis drive mechanism 41 as an example, refer to Figure 7 The first piezoelectric mechanism includes a first piezoelectric block 411, a first friction rod 412, a sleeve 413, and a mounting component 414. One end of the first piezoelectric block 411 is fixed to the base 10 or a fixing component via a first counterweight plate 415, and the other end of the first piezoelectric block 411 is fixedly connected to the first friction rod 412. At this time, the length direction and movement direction of the first friction rod 412 are both in the X-axis direction. The first friction rod 412 is fitted with a sleeve 413. Since the sleeve 413 is elastic, it is tightly attached to the outside of the first friction rod 412, so that the sleeve 413 can move along with the first friction rod 412. The sleeve 413 is engaged with the mounting component 414 provided on the outer wall of the X-axis movable frame 31. After the first piezoelectric block 411 is energized, the first friction rod 412, the sleeve 413, and the mounting component 414 drive the X-axis movable frame 31 to move in the X-axis direction.

[0092] In this embodiment, the fixing component can be another component in the lens driving device. This component is used to install the first piezoelectric block 411 or the first counterweight plate 415. The X-axis movable frame 31 and the Y-axis movable frame 31 can move relative to this component in the X-axis direction and in the Y-axis direction.

[0093] In one embodiment, reference is made to Figure 2 , Figure 3 and Figure 5 The staggered horizontal moving platform also includes a frame 60, which is located outside the X-axis movable frame 31 and the Y-axis movable frame 32. At this time, the frame 60 acts as a fixed component, and the X-axis drive mechanism 41 and the Y-axis drive mechanism 42 are respectively installed on the frame 60. The frame 60 is connected to the X-axis movable frame 31 and the Y-axis movable frame 32 through the X-axis drive mechanism 41 and the Y-axis drive mechanism 42, so that when the frame 60 moves in the Z-axis direction, the X-axis movable frame 31, the Y-axis movable frame 32 and the carrier 20 on them move in the Z-axis direction.

[0094] The drive mechanism includes a Z-axis drive mechanism 43, which drives the frame 60, the X-axis movable frame 31, the Y-axis movable frame 32, and the carrier 20 to move relative to the base 10 in the Z-axis direction, thereby realizing the zoom operation of the lens mounted on the carrier 20.

[0095] In one embodiment, reference is made to Figure 1 and Figure 2 A second spring 52 is installed between the frame 60 and the base 10.

[0096] The second spring 52 connects the frame 60 and the base 10 respectively. The setting of the second spring 52 enables the frame 60 to have a stable reset effect after moving in the Z-axis direction.

[0097] The second spring 52 preferably adopts an L-shaped structure. The second spring 52 is horizontally arranged, and its two ends have frame connecting parts that connect to the top surface of the frame 60. The corner of the second spring 52 has a base connecting part that connects to the top surface of the base 10. The two frame connecting parts are respectively connected to the base connecting parts by elastic spring wires.

[0098] In one embodiment, the Z-axis drive mechanism 43 employs one of a piezoelectric mechanism, an electromagnetic drive mechanism, and a shape memory alloy drive mechanism. The Z-axis drive mechanism 43 may also employ other drive mechanisms already known in the art.

[0099] The Z-axis drive mechanism 43 preferably adopts a piezoelectric mechanism.

[0100] In one embodiment, the Z-axis drive mechanism 43 employs a second piezoelectric mechanism, as shown in the reference. Figures 1 to 3The second piezoelectric mechanism includes a second piezoelectric block 431, a second friction rod 432, and an elastic plate 433. The bottom end of the second piezoelectric block 431 is fixed to the base 10 or fixed to the base 10 via a second counterweight plate 434. The top end of the second piezoelectric block 431 is fixedly connected to the second friction rod 432. At this time, the length direction and movement direction of the second friction rod 432 are both in the Z-axis direction. The two ends of the elastic plate 433 are fixedly connected to the side wall of the frame 60 respectively. The second friction rod 432 is located between the elastic plate 433 and the side wall of the frame 60. The elasticity of the elastic plate 433 squeezes the second friction rod 432 into the V-groove of the side wall of the frame 60. After the second piezoelectric block 431 is energized, the second friction rod 432 drives the frame 60, the X-axis movable frame 31, the Y-axis movable frame 32, and the carrier 20 to move relative to the base 10 in the Z-axis direction.

[0101] In a specific implementation, preferably, the base 10 is provided with a piezoelectric block clearance hole 11, and the bottom end of the second piezoelectric block 431 passes through the piezoelectric block clearance hole 11 and is fixedly connected to the base 10, or the bottom end of the second piezoelectric block 431 passes through the piezoelectric block clearance hole 11 and is fixedly connected to the counterweight plate 434 fixed on the base 10.

[0102] In one embodiment, the staggered horizontal moving platform further includes a housing 70, which is detachably connected to the base 10 to form a hollow cavity. The carrier 20, the movable frame, and the drive mechanism are all disposed within the hollow cavity.

[0103] The outer shell 70 and the base 10 are preferably connected by a snap-fit ​​connection.

[0104] Example 2:

[0105] Reference Figures 8 to 10 This embodiment provides an interleaved horizontal moving platform. Compared with Embodiment 1, the interleaved horizontal moving platform adopts the following design to reduce friction structure. The remaining structures are the same as those provided in Embodiment 1, and will not be described again here.

[0106] In this embodiment, in order to reduce the friction between the contact ramp and the guide ramp during relative movement, a ball bearing structure is adopted to reduce the friction, specifically:

[0107] Ball grooves are provided on the X-axis contact slope 210, X-axis guide slope 320, Y-axis contact slope 220, and Y-axis guide slope 310 respectively. The ball grooves between the X-axis contact slope 210 and the X-axis guide slope 320 are arranged opposite each other and are equipped with balls. The ball grooves between the Y-axis contact slope 220 and the Y-axis guide slope 310 are arranged opposite each other and are equipped with balls. The friction is reduced by the rolling cooperation of the balls in the ball grooves. The number of ball grooves and balls is not limited, and the number of balls in a single ball groove is also not limited.

[0108] Taking the X-axis contact inclined surface 210 and the X-axis guide inclined surface 320 as examples, refer to Figures 8 to 10 Two X-axis contact ramps 210 are provided at the bottom of the carrier 20. Each X-axis contact ramp 210 is provided with a first ball groove 212. Two X-axis guide ramps 320 are provided on the Y-axis movable frame 32. Each X-axis guide ramp 320 is provided with a second ball groove 322. Each first ball groove 212 and a corresponding second ball groove 322 are arranged opposite to each other to form an X-axis ball groove. Each ball 81 is located in the X-axis ball groove formed by the opposite arrangement of the first ball groove 212 and the second ball groove 322. The friction between the X-axis contact ramp and the X-axis guide ramp during relative movement is reduced by the rolling of the ball 81 in the X-axis ball groove.

[0109] Example 3:

[0110] Reference Figure 11 and Figure 12 This embodiment provides an interleaved horizontal moving platform. Compared with Embodiment 1, the interleaved horizontal moving platform adopts the following design to reduce friction structure. The remaining structures are the same as those provided in Embodiment 1, and will not be described again here.

[0111] In this embodiment, in order to reduce the frictional force between the contact inclined surface and the guide inclined surface during relative movement, the friction reduction structure adopts an embedded part structure, specifically:

[0112] The X-axis movable frame 31 contains an X-axis movable frame built-in metal 82, which protrudes from the Y-axis guide ramp 310. The Y-axis movable frame 32 contains a Y-axis movable frame built-in metal 83, which protrudes from the X-axis guide ramp 320. The number of X-axis movable frame built-in metal 82 and Y-axis movable frame built-in metal 83 can be determined according to the number of Y-axis guide ramps 310 and X-axis guide ramps 320, ensuring that one guide ramp corresponds to one or more movable frame built-in metals. Figure 11 and Figure 12 As shown, it has two Y-axis guide ramps 310 and two X-axis guide ramps 320. The metal 82 inside the two X-axis movable frames is exposed on the corresponding Y-axis guide ramps 310, and the metal 83 inside the two Y-axis movable frames is exposed on the corresponding X-axis guide ramps 320.

[0113] The carrier 20 contains a built-in carrier metal 84. At least two protruding plates 841 are provided at the bottom of the built-in carrier metal 84. These protruding plates 841 extend from the X-axis contact slope 210 and the Y-axis contact slope 220, respectively. That is, one or more protruding plates 841 extend from the X-axis contact slope 210, and another or more protruding plates 841 extend from the Y-axis contact slope 220. Each protruding plate 841 contacts and can slide relative to the corresponding X-axis movable frame built-in metal 82 or Y-axis movable frame built-in metal 83. The number of protruding plates 841 can be determined according to the number of movable frame built-in metals, ensuring that each movable frame built-in metal corresponds to one or more protruding plates 841. Figure 12 As shown, four protruding plates 841 are provided at the bottom of the carrier built-in metal 84. The four protruding plates 841 contact the corresponding X-axis movable frame built-in metal 82 and Y-axis movable frame built-in metal 83 respectively and can slide relative to each other.

[0114] Since the protruding plate 841 has a smaller contact surface compared to the contact slope, the design of the protruding plate 841 and the built-in metal of the movable frame reduces the friction when the carrier 20 moves and enhances the structural strength of the carrier 20 and the movable frame.

[0115] In one embodiment, both the X-axis movable frame built-in metal 82 and the Y-axis movable frame built-in metal 83 have inclined surfaces. The inclined surface of the X-axis movable frame built-in metal 82 has the same inclination direction and angle as the inclined surface on the Y-axis guide inclined surface 310, so that the inclined surface of the X-axis movable frame built-in metal 82 fits against and is exposed on the inclined surface on the Y-axis guide inclined surface 310. Similarly, the inclined surface of the Y-axis movable frame built-in metal 83 has the same inclination direction and angle as the inclined surface on the X-axis guide inclined surface 320, so that the inclined surface of the Y-axis movable frame built-in metal 83 fits against and is exposed on the inclined surface on the X-axis guide inclined surface 320.

Compared with Embodiment 1, the interlaced horizontal moving platform adopts a different pressing structure, while the rest of the structure is the same as the embodiments provided in Embodiment 1, and will not be described again here.

[0118] In this embodiment, in order to ensure stable contact between the contact slope at the bottom of the carrier 20 and the guide slope on the movable frame, the clamping structure adopts a magnetic attraction structure, specifically:

[0119] The pressing structure includes one or more magnetic components and magnets. One of the magnetic components and magnets is located at the bottom of the carrier 20, and the other is located at the bottom of at least one of the X-axis movable frame 31 and the Y-axis movable frame 32 or the top of the base 10. Each magnetic component and its corresponding magnet are arranged opposite to each other and attract each other. The carrier 20 is pressed onto the X-axis movable frame 31 and the Y-axis movable frame 32 by the attraction force of the magnetic components and magnets.

[0120] The number of magnetic components and magnets can be set according to actual needs, and therefore is not limited. For example, refer to... Figures 13 to 16 Three magnetic components 53 are respectively installed in three magnetic component mounting slots 531 at the bottom of the carrier 20, and three magnets 54 are respectively installed in three magnet mounting slots 541. One magnet mounting slot 541 is located at the bottom of the X-axis movable frame 31, and two magnet mounting slots 541 are located at the bottom of the Y-axis movable frame 32.

The carrier from Embodiment 1 is replaced with a substrate, and an image sensor is mounted on the substrate. The X-axis and Y-axis drive mechanisms directly control the X-axis and Y-axis movable frames, which in turn drive the substrate and the image sensor to move in the X-axis and Y-axis directions, respectively, thus forming a chip anti-shake structure. This chip anti-shake structure can be applied to a chip anti-shake motor structure, achieving the motor's OIS anti-shake effect through the movement and anti-shake action of the image sensor.
