[0044] In one embodiment of the present invention, the driving unit includes a stator component 101 and a mover assembly 102 .

[0045] Specifically, the stator component 101 includes a drive circuit 1012, and the drive circuit 1012 is fixed in the housing 1011. The drive circuit 1012 can be fixed to the inner top surface of the housing 1011, or the drive circuit 1012 can also be fixed to the upper side wall of the housing 1011.

[0047] Please refer to Figure 1 and Figure 2In one embodiment of the present invention, the movable subassembly 102 includes an X-direction moving unit 1021 , an X-direction spring piece 1022 , a Y-direction moving unit 1023 and a Y-direction spring piece 1024 .

[0048] Among them, the X-direction moving unit 1021 and the Y-direction moving unit 1023 are connected to the driving circuit 1012, and the driving circuit 1012 can drive the X-direction moving unit 1021 and the Y-direction moving unit 1023 to move in the X-direction and the Y-direction respectively; that is, the driving circuit 1012 can drive the X-direction moving unit 1021 to move in the positive direction of the X-direction or the negative direction of the X-direction, and the driving circuit 1012 can also drive the Y-direction moving unit 1023 to move in the positive direction of the Y-direction or the negative direction of the Y-direction.

[0049] Further, the X-direction spring piece 1022 is connected to the housing 1011 and the X-direction moving unit 1021, respectively, and the X-direction spring piece 1022 can reset the position of the X-direction moving unit 1021; the Y-direction spring piece 1024 is connected to the housing 1011 and the Y-direction moving unit 1023, respectively, and the Y-direction spring piece 1024 can reset the position of the Y-direction moving unit 1023. In this embodiment, the X-direction spring piece 1022 and the Y-direction spring piece 1024 are arranged perpendicular to each other, so that not only the X-direction spring piece 1022 and the Y-direction spring piece 1024 are convenient for elastic reset, the reset directionality and position accuracy are better, and the mutual interference is reduced, but also the X-direction spring piece 1022 and the Y-direction spring piece 1024 are convenient for reducing the interference with the layout of other parts in the housing 1011, improving the space utilization rate, and reducing the volume of the driving module 10.

[0050] In one embodiment of the present invention, the driving circuit 1012 includes a circuit board 10121, an X-direction coil 10122 and a Y-direction coil 10123, wherein the X-direction coil 10122 is wound on two opposite sides of the circuit board 10121 in the X direction, and the Y-direction coil 10123 is wound on two opposite sides of the circuit board 10121 in the Y direction. It should be noted that the circuit board 10121 may be an image sensor circuit board, and the circuit board 10121 has an avoidance groove inside for avoiding parts (such as a lens assembly) installed on a focus motor, and a winding plate structure is provided outside the circuit board 10121 to facilitate the winding of the X-direction coil 10122 and the Y-direction coil 10123.

[0051] Furthermore, a driving power supply is provided on the circuit board 10121, and the driving power supply can supply power to the X-direction coil 10122 and the Y-direction coil 10123, and a signal terminal is provided on the circuit board 10121, and the signal terminal can receive a feedback signal from the image sensor. Then, after the feedback signal is processed and calculated, the circuit board 10121 supplies power to the X-direction coil 10122 and / or the Y-direction coil 10123, drives the X-direction moving unit 1021 and the Y-direction moving unit 1023 to move along the X-direction and / or Y-direction, and realizes an automatic anti-shake function.

[0052] It should be noted that in this embodiment, the number of the X-direction coils 10122 and the number of the Y-direction coils 10123 are both two or more. That is, the number of the X-direction coils 10122 can be two, four, six or more, and the number of the Y-direction coils 10123 can be two, four, six or more.

[0053] In one embodiment of the present invention, the X-direction moving unit 1021 includes an X-direction bracket 10211 and an X-direction magnet 10212. The X-direction magnet 10212 is disposed on two opposite sides of the X-direction bracket 10211 in the X-direction, and the X-direction magnet 10212 cooperates with the X-direction coil 10122. Figure 4 , Figure 4 10211 is a schematic diagram of the structure of the X-axis bracket of the driving module of the present invention. The main body of the X-axis bracket 10211 needs to be provided with a hole for avoiding the focus motor. Therefore, the X-axis bracket 10211 can be in a continuous square frame, circular ring, elliptical ring or other shape. Figure 4 As shown, the main body of the X-direction bracket 10211 in this embodiment is in a continuous square frame shape, and the X-direction magnet 10212 is installed on the square frame at two opposite sides in the X direction. When the X-direction coil 10122 is energized, the X-direction magnet 10212 generates a Lorentz force to push the X-direction bracket 10211 to move along the X direction.

[0054] In one embodiment of the present invention, the Y-direction moving unit 1023 includes a Y-direction bracket 10231 and a Y-direction magnet 10232. The Y-direction magnet 10232 is disposed on two opposite sides of the Y-direction bracket 10231 in the Y direction, and the Y-direction magnet 10232 cooperates with the Y-direction coil 10123. Figure 6 , Figure 6 1 is a schematic diagram of the structure of the Y-axis bracket of the driving module of the present invention. The Y-axis bracket 10231 is similar to the X-axis bracket 10211. The main body of the Y-axis bracket 10231 can be in a continuous square frame, circular, elliptical or other shape. Figure 5As shown, the main body of the Y-direction bracket 10231 in this embodiment is in the form of a continuous square frame, and the Y-direction magnet 10232 is installed on the square frame on opposite sides of the Y direction. When the Y-direction coil 10123 is energized, the Y-direction magnet 10232 will generate a Lorentz force to push the Y-direction bracket 10231 to move along the Y direction.

[0055] It should be noted that the upper and lower positions of the X-direction bracket 10211 and the Y-direction bracket 10231 in the present invention are adjustable in the housing 1011. That is to say, the X-direction bracket 10211 can be arranged above the Y-direction bracket 10231, and the X-direction bracket 10211 can also be arranged below the Y-direction bracket 10231. In addition, in order to ensure that all X-direction magnets 10212 and all Y-direction magnets 10232 are in the same plane, it is convenient to control the gap between the X-direction magnet 10212 and the X-direction coil 10122, and between the Y-direction magnet 10232 and the Y-direction coil 10123, ensure the installation accuracy and anti-shake stroke accuracy, and reduce the difficulty of processing and installation, the bracket located above can be provided with an avoidance groove to avoid the magnet installation groove on the bracket below. For example, two avoidance grooves 10234 are provided in the X direction on the upper Y-direction bracket 10231, and a portion of the lower X-direction bracket 10211 can extend into the avoidance grooves 10234, so that all X-direction magnets 10212 and all Y-direction magnets 10232 are in the same plane.

[0056] See also Figure 5 , Figure 5 It is a schematic diagram of the structure of the X-direction spring piece of the driving module of the present invention. In one embodiment of the present invention, the X-direction spring piece 1022 includes a first middle connecting section 10221, a first elastic arm 10222 and two first end connecting sections 10223, the two first end connecting sections 10223 are located on both sides of the first middle connecting section 10221, and the two first end connecting sections 10223 are connected to both sides of the first middle connecting section 10221 through the first elastic arm 10222, wherein the two first end connecting sections 10223 are connected to the inner side wall of the housing 1011, and the first middle connecting section 10221 is connected to the X-direction bracket 10211. In this embodiment, when the X-direction coil 10122 is energized, under the action of the Lorentz force, the X-direction bracket 10211 moves along the X-direction. At this time, the first intermediate connecting section 10221 will move synchronously with the X-direction bracket 10211, while the first end connecting section 10223 remains fixed to the outer shell 1011, and the first elastic arm 10222 is deformed; and when the X-direction coil 10122 is de-energized, the first elastic arm 10222 returns to its original shape under the action of its own elastic force, thereby driving the X-direction bracket 10211 to return to its original position.

[0057] See also Figure 7 , Figure 7 1 is a schematic diagram of the structure of the Y-direction spring piece of the driving module of the present invention. In one embodiment of the present invention, the Y-direction spring piece 1024 includes a second middle connecting section 10241, a second elastic arm 10242 and two second end connecting sections 10243, the two second end connecting sections 10243 are located on both sides of the second middle connecting section 10241, and are connected to both sides of the second middle connecting section 10243 through the second elastic arm 10242, wherein the two second end connecting sections 10243 are connected to the inner side wall of the housing 1011, and the second middle connecting section 10241 is connected to the Y-direction bracket 10231. In this embodiment, when the Y-direction coil 10123 is energized, under the action of the Lorentz force, the Y-direction bracket 10231 moves along the Y-direction. At this time, the second intermediate connecting section 10241 will move synchronously with the Y-direction bracket 10231, while the second end connecting section 10243 remains fixed to the outer shell 1011, and the second elastic arm 10242 is deformed; and when the Y-direction coil 10123 is de-energized, the second elastic arm 10242 returns to its original shape under the action of its own elastic force, driving the Y-direction bracket 10231 back to its original position.

[0058] In one embodiment of the present invention, the first end connecting section 10223 and the second end connecting section 10243 have tooth structures 1025. Specifically, the tooth structures 1025 can be composed of staggered grooves 10251 and block-shaped protrusions 10252. Such a configuration can increase the contact area between the first end connecting section 10223 and the inner side wall of the shell 1011, and between the second end connecting section 10243 and the inner side wall of the shell 1011, thereby improving the connection strength between the first end connecting section 10223 and the shell 1011, and between the second end connecting section 10243 and the shell 1011. In other embodiments of the present invention, the first end connecting section 10223 and the second end connecting section 10243 can also be directly provided with structures such as reinforcing ribs and connecting plates to increase the contact area with the shell 1011.

[0059] In one embodiment of the present invention, the first elastic arm 10222 and the second elastic arm 10242 are made of spring wire, and their shapes are both "J"-shaped. In this way, not only is the structure simple, the production and processing are convenient, but also there is a certain elastic restoring force in the X direction and the Y direction. Take the first elastic arm 10222 as an example: when the X-direction bracket 10211 and the Y-direction bracket 10231 are equipped with parts (such as: image sensor) at the same time, after the Y-direction coil 10123 is energized, the Y-direction bracket 10231 will move along the Y direction with the image sensor, and the image sensor will drive the X-direction bracket 10211 to move along the Y direction. At this time, the first elastic arm 10222 can make the first middle connecting section 10221 and the two first end connecting sections 10223 stretch and separate along the Y direction, so as to realize the movement of the X-direction bracket 10211 along the Y direction, and will not affect the movement of the X-direction bracket 10211 along the X direction.

[0060] Optionally, in order to avoid the twisting deformation of the first elastic arm 10222 and the second elastic arm 10242 in the unstressed state, which may affect the elastic restoring force, the first middle connecting section 10221, the first elastic arm 10222 and the two first end connecting sections 10223 are located on the same plane; the second middle connecting section 10241, the second elastic arm 10242 and the two second end connecting sections 10243 are located on the same plane.

[0061] In one embodiment of the present invention, a first protrusion 10213 is provided on the outer side of the X-direction bracket 10211, and a first groove 10224 is provided on the X-direction spring piece 1022, and the first groove 10224 cooperates with the first protrusion 10213; a second protrusion 10233 is provided on the outer side of the Y-direction bracket 10231, and a second groove 10244 is provided on the Y-direction spring piece 1024, and the second groove 10244 cooperates with the second protrusion 10233. In this embodiment, the number of the first protrusion 10124 and the second protrusion 10233 can be one or more. Specifically, the left and right side walls of the first groove portion 10224 can contact the left and right side walls of the first protrusion 10125, and the left and right side walls of the second groove portion 10244 can contact the left and right side walls of the second protrusion 10233. In this way, when the X-axis bracket 10211 and the Y-axis bracket 10231 move, the firmness of the connection between the X-axis spring piece 1022 and the X-axis bracket 10211, and between the Y-axis spring piece 1024 and the Y-axis bracket 10231 can be maintained.
