Correspondingly, the housing 11 is also provided with a light transmission part 113, which can be provided as a light transmission hole or a cover structure made of plastic, glass or the like that can transmit light.

[0052] With reference to FIGS. 3 and 4, in an embodiment of the present application, the camera module 20 includes the optical component 21 and the driving motor 30; the optical component 21 includes the lens assembly 211 and the image sensor 212 arranged oppositely, one of the lens assembly 211 and the image sensor 212 is carried on the first plate segment 321, and the other of the lens assembly 211 and the image sensor 212 is fixed oppositely to the seat plate 310; for example, the lens assembly 211 is carried on the first plate segment 321, and the image sensor 212 is fixed oppositely to the seat plate 310. The image sensor 212 can be directly fixed to the seat plate 310, or the image sensor 212 can be indirectly fixed to the seat plate 310 through other structures. The lens assembly 211 can include a lens, and the lens assembly 211 has an optical axis O.

[0054] The optical axis O of the lens assembly 211 can be arranged perpendicular to the back cover 112 in FIG. 1, which can be understood as that the optical axis O is arranged along the thickness direction of the electronic device 10; of course, the camera module 20 can also form a periscopic lens by adding a reflecting prism, and the optical axis O of the lens assembly 211 can be correspondingly arranged parallel to the back cover 112 in FIG. 1, which is not limited in the present embodiment.

[0055] When the electronic device 10 is provided with a lens assembly 211 with a large aperture and a large quality, with reference to FIG. 3, the diameter D of the lens assembly 211 is usually large, and the weight of the lens assembly 211 is also increased. Therefore, with reference to FIG. 4, when the lens assembly 211 needs to be moved in a first direction (for example, the X-axis direction in the figure), the lens assembly 211 sometimes moves in a second direction (for example, the Y-axis direction in the figure) which is perpendicular to the first direction and parallel to the plate surface of the second plate segment 322, resulting in that the efficiency of the shake compensation of the lens assembly 211 is low, and even the shake compensation of the lens assembly 211 is not in place, thereby causing imaging blur.

The carrier plate 320 can be understood as a plate member for supporting the optical components 21, for example, a plate member for supporting the above-mentioned lens assembly 211. In some embodiments, the projection of the carrier plate 320 in the thickness direction can be set as a rectangle or a rectangle with rounded corners, thereby facilitating the reduction of the overall width of the carrier plate 320 and the driving motor 30, and improving the applicability of the driving motor 30 to narrow spaces.

Of course, the driving motor 30 can also not include the above-mentioned AF focusing assembly, which is not limited in this embodiment.

[0059] Referring to FIG. 5, the seat plate 310 can be provided with a second through structure 311, which is arranged opposite to the first through structure 324, thereby facilitating the light passing through the lens assembly 211 to reach the image sensor 212.

In addition, the retaining ring 361 can be provided as a cylindrical shape, an elliptical cylindrical shape, a square cylindrical shape or the like, which is not limited in this embodiment.

[0061] Of course, in other alternative embodiments, the carrier plate 320 and the seat plate 310 can also be connected and relatively movable through a sliding shaft, a suspension wire, a guide rail or the like structure.

[0063] Similarly, when the carrier plate 320 and the lens assembly 211 on the carrier plate 320 need to move along the Y-axis direction in the drawing, the component of the driving force of the first driving assembly 330 in the X-axis direction and the component of the driving force of the second driving assembly 340 in the X-axis direction can be opposite in direction and equal in size, and the component of the driving force of the first driving assembly 330 in the Y-axis direction and the component of the driving force of the second driving assembly 340 in the Y-axis direction can be the same in direction and form a resultant force. Further, the first driving assembly 330 and the second driving assembly 340 can be configured to simultaneously move the driving force towards or away from the first plate segment 321, for example, the driving force F1 of the first driving assembly 330 in FIG. 4 is towards the first plate segment 321, and the driving force F2 of the second driving assembly 340 is also towards the first plate segment 321.

[0064] It can be understood that in this embodiment, in two directions perpendicular to each other and parallel to the plate surface of the second plate segment, for example, in the X-axis direction and the Y-axis direction in FIG. 4, the first driving assembly 330 and the second driving assembly 340 can provide opposite components in a first direction, for example, in the X-axis direction in FIG. 4, and the same components in a second direction, for example, in the Y-axis direction in FIG. 4, so as to inhibit the movement of the carrier plate 320 and the corresponding optical component 21 in the first direction, for example, in the X-axis direction in FIG. 4, and drive the movement of the carrier plate 320 and the corresponding optical component 21 in the second direction, for example, in the Y-axis direction in FIG. 4, which is beneficial to improve the efficiency of the dithering compensation. In addition, the carrier plate 320 comprises the first plate segment 321 and the second plate segment 322 arranged in sequence in the first direction X, and the first driving assembly 330 and the second driving assembly 340 are respectively mounted on the second plate segment 322, which is beneficial to reduce the average width of the carrier plate 320 and improve the space utilization of the driving motor 30 in the second direction Y of the carrier plate 320. It can be understood that the driving motor 30 in this embodiment can be suitable for a relatively narrow space. The carrier plate 320 is mounted with the optical component 21, the first driving assembly 330 and the second driving assembly 340, and the driving motor 30 is relatively flat as a whole.

[0065] Further, the driving force direction of the first driving assembly 330 and the driving force direction of the second driving assembly 340 can be set to be symmetrical about the first direction X of the carrier plate 320, so as to facilitate the carrier plate 320 to be restrained from moving in the first direction and driven to move in the second direction under the condition that the first driving assembly 330 and the second driving assembly 340 provide driving forces of the same size, and facilitate the control signal of the driving motor 30 to be simplified. In some embodiments, the included angle between the driving force direction of the first driving assembly 330 and the first direction X of the carrier plate 320 can be set to be greater than 0 degrees and less than 90 degrees, for example, 30 degrees, 45 degrees, 60 degrees, etc. The included angle between the driving force direction of the second driving assembly 340 and the first direction X of the carrier plate 320 can be set to be greater than 0 degrees and less than 90 degrees, for example, 30 degrees, 45 degrees, 60 degrees, etc. Further, the included angle between the driving force direction of the first driving assembly 330 and the driving force direction of the second driving assembly 340 can be set to be greater than or equal to 30 degrees and less than or equal to 90 degrees, for example, 30 degrees, 60 degrees, 90 degrees, etc.

For example, the first magnet 331 is mounted on the second plate segment 322, and the first coil 332 is fixed relative to the seat plate 310. In some embodiments, the first magnet 331 can be mounted on the second plate segment 322 by adhesion or the like, and the first magnet 331 can be embedded on the second plate segment 322 to improve the connection stability of the first magnet 331, for example, the first magnet 331 can be embedded on the second plate segment 322 by encapsulation process.

In some embodiments, the included angle between the length direction of the first straight segment 333 and the first direction X is set to be an acute angle, which can be understood as the included angle between the length direction of the first straight segment 333 and the first direction X is less than 90 degrees, so as to facilitate the first coil 332 to be closer to the first direction X as a whole, and facilitate the average width of the second plate segment 322 and the carrier plate 320 to be reduced.

[0068] In some embodiments, referring to FIGS. 4 and 5, the second driving assembly 340 includes a second magnet 341 and a second coil 342, one of the second magnet 341 and the second coil 342 is mounted on the second plate segment 322, and the other of the second magnet 341 and the second coil 342 is fixed opposite to the seat plate 310. For example, the second magnet 341 is mounted on the second plate segment 322, and the second coil 342 is fixed opposite to the seat plate 310; wherein the second magnet 341 can be mounted on the second plate segment 322 by bonding or the like, and the second magnet 341 can also be embedded on the second plate segment 322 to improve the connection stability of the second magnet 341, for example, the second magnet 341 can be embedded on the second plate segment 322 by a gluing process. Of course, the second coil 342 can also be mounted on the second plate segment 322, and the second magnet 341 is fixed opposite to the seat plate 310, which is not limited in the present embodiment. In addition, the second coil 342 can include at least one segment of second straight segments 343, the length direction of the second straight segments 343 is parallel to the plate surface of the second plate segment 322, and the length direction of the second straight segments 343 has an angle with the first direction X and the second direction Y, respectively; the length direction of the second straight segments 343 has an angle with the length direction of the first straight segments 333 (the angle can refer to the angle B in FIG. 4), for example, the length direction of the second straight segments 343 has an angle with the X-axis direction and the Y-axis direction in the figure, respectively, so as to facilitate the second coil 342 to provide driving force having an angle with the first direction X and the second direction Y, respectively, through the second straight segments 343. In some embodiments, the angle between the length direction of the second straight segments 343 and the first direction X is an acute angle, which can be understood as the angle between the length direction of the second straight segments 343 and the first direction X is less than 90 degrees, so as to facilitate the second coil 342 to be closer to the first direction X as a whole, and to facilitate reducing the average width of the second plate segment 322 and the carrier plate 320.

[0069] In some embodiments, referring to FIGS. 5 and 6, the second coil 342 can include two second straight sections 343 and two second arc sections 344, the first second straight section 343, the first second arc section 344, the second second straight section 343 and the second second arc section 344 are connected in sequence, so that the second driving assembly 340 provides greater driving force through the two second straight sections 343. It can be understood that the second arc section 344 can also be arranged parallel to the plate surface of the second plate section 322, so that the entire second coil 342 is parallel to the plate surface of the second plate section 322, so that the driving motor 30 is more compact in structure.

[0070] Referring to FIGS. 5 and 8, the magnetization direction of the second magnet 341 can be arranged perpendicular to the second plate section 322; specifically, the second driving assembly 340 can be provided with two second magnets 341, and the two second magnets 341 are arranged one-to-one corresponding to the two second straight sections 343. Among them, one second magnet 341 can be arranged with N pole facing the corresponding second straight section 343, and the other second magnet 341 can be arranged with S pole facing the corresponding second straight section 343, so that according to the left-hand rule of the force of the current-carrying wire in the magnetic field, the two second straight sections 343 belonging to the second coil 342 can provide driving force in the same direction, thereby facilitating the second coil 342 to provide greater acting force to the outside. It can be understood that the first driving assembly 330 can adopt a similar magnetic pole layout, which will not be described here in this embodiment.

[0071] In some embodiments, the driving part for providing driving force in the driving motor 30 can be composed of the above-mentioned first driving assembly 330 and the above-mentioned second driving assembly 340, and it can be understood that the driving part in the driving motor 30 can be arranged to include only the above-mentioned first driving assembly 330 and the above-mentioned second driving assembly 340.

[0072] The cross section of the lens assembly 211 is generally close to a circle, and the space utilization of the area near the lens assembly 211 in the related art is low. Referring to FIGS. 5 and 6, in some embodiments, the first flat section 333 and the second flat section 343 surround an included angle region 345 with an included angle less than 180 degrees, and the opening of the included angle region 345 is arranged to face the first plate section 321. The included angle region 345 surrounded by the first flat section 333 and the second flat section 343 can be understood as a C-shaped space, and the included angle of the included angle region 345 can be understood as the included angle B between the length direction of the second flat section 343 and the length direction of the first flat section 333, so that the included angle region 345 is more consistent in shape with the outer circumferential surface of the lens assembly 211, so that the first flat section 333 and the second flat section 343 can be assembled closer to the lens assembly 211, thereby improving the space utilization of the driving motor 30 and improving the structural compactness of the driving motor 30. In some embodiments, the angle B surrounded by the first flat section 333 and the second flat section 343 is less than 180 degrees, thereby facilitating the overall closer of the first coil 332 and the second coil 342, and facilitating the reduction of the average width of the second plate section 322 and the carrier plate 320. It can be understood that the angle B between the length direction of the second flat section 343 and the length direction of the first flat section 333 can be further greater than 0 degrees and less than or equal to 90 degrees, or even greater than 0 degrees and less than 90 degrees, thereby further reducing the average width of the second plate section 322 and the carrier plate 320.

[0073] In some embodiments, referring to FIG. 4, the driving force F1 of the first driving assembly 330 and the driving force F2 of the second driving assembly 340 form a driving intersection point P when projected in a direction perpendicular to the carrier plate 320, for example, a partial structure diagram in the upward direction as shown in FIG. 4. The projection of the central axis of the first through structure 324 is arranged to be spaced apart from the driving intersection point P in the first direction X, for example, to form a spacing L in FIG. 4. In this embodiment, when the electronic device 10 is provided with a large-aperture, high-quality lens assembly 211 with better optical performance, the weight of the lens assembly 211 is comparable to the overall weight of the two driving assemblies, i.e., the first driving assembly 330 and the second driving assembly 340. Therefore, after the first through structure 324 is loaded with the lens assembly 211, the overall center of gravity of the lens assembly 211, the first driving assembly 330 and the second driving assembly 340 becomes closer to the driving intersection point P, thereby facilitating the reduction of the length of the deflection arm of the first driving assembly 330 and the second driving assembly 340 on the carrier plate 320, facilitating the reduction of the risk of rotation of the lens assembly 211, facilitating the improvement of the efficiency of the shake compensation, and facilitating the improvement of the imaging clarity. It can be understood that the optical axis O is a projection point after being projected in a direction perpendicular to the carrier plate 320.

[0074] In some embodiments, the driving motor 30 comprises a moving assembly, the moving assembly comprising the above-mentioned carrier plate 320 and a fixed component fixed on the carrier plate 320, the fixed component may, for example, comprise the above-mentioned first magnet 331 and the second magnet 341. The moving assembly may be understood as an assembly that can move relative to the seat plate 310. The driving motor 30 is configured to project in a direction perpendicular to the carrier plate 320, and the distance between the above-mentioned driving intersection P and the center of gravity of the moving assembly is less than or equal to a preset distance; wherein the preset distance may be set to be less than or equal to 5 millimeters. For example, the distance between the above-mentioned driving intersection P and the center of gravity of the moving assembly may be set to be equal to zero, which may be understood as that the above-mentioned driving intersection P coincides with the center of gravity of the moving assembly.

[0075] In this embodiment, the distance between the above-mentioned driving intersection P and the center of gravity of the moving assembly is less than or equal to the preset distance, which is beneficial to further reduce the length of the deflection arm of the first driving assembly 330 and the second driving assembly 340 on the carrier plate 320, and is beneficial to further reduce the risk of rotation of the lens assembly 211, and is beneficial to further improve the imaging clarity.

[0076] Specifically, referring to FIG. 5, the second plate segment 322 can be provided with a counterweight 350; along the first direction X, the counterweight 350 is arranged on the side of the first driving assembly 330 away from the first plate segment 321, for example, the counterweight 350 is arranged on the right side in FIG. 5. Wherein, under the premise that the distance between the above-mentioned driving intersection P and the center of gravity of the moving assembly is less than or equal to the preset distance, the weight and the specific fixing position of the counterweight 350 can be determined, so as to conveniently and quickly make the distance between the above-mentioned driving intersection P and the center of gravity of the moving assembly less than or equal to the preset distance, thereby facilitating the design and manufacturing difficulty of the driving motor 30. Wherein, the counterweight 350 can be arranged on the second plate segment 322 by clamping, bonding or the like.

For example, the abutting plate 362 can be made of LCP plastic material (LCP, Liquid Crystal Polymer) or 316 stainless steel or other metals, the carrier plate 320 can be made of plastic material with relatively low hardness, and the ball 360 can be made of ceramic material or metal.

[0079] In some embodiments, along the first direction X, for example, along the X-axis direction in FIG. 6 or FIG. 8, at least part of the ball 360 is arranged on the side of the first driving assembly 330 away from the first plate segment 321, for example, part of the ball 360 is arranged on the right side in the figure; Correspondingly, the corresponding retainer ring 361 and abutting plate 362 of the ball 360 are also arranged on the side of the first driving assembly 330 away from the first plate segment 321, for example, are arranged on the right side in the figure, thereby facilitating reducing the distance between the driving intersection P of the driving force and the center of gravity of the moving assembly including the carrier plate 320, facilitating further reducing the risk of rotation of the lens assembly 211, and facilitating further improving the imaging clarity.

The first magnetic sensing element 374 can be arranged as a Hall element, a TMR element (Tunnel Magnet Resistance), etc., and the second magnetic sensing element 376 can be arranged as a Hall element, a TMR element (Tunnel Magnet Resistance), etc., and the above-mentioned first magnet 331, second magnet 341, third magnet 373 and fourth magnet 375 can be respectively arranged as a magnetic stone and a magnet.

[0081] In this embodiment, the driving motor 30 can realize position feedback of the jitter compensation through the to-be-detected structure 371 and the detection component 372, thereby facilitating to improve the accuracy of the jitter compensation. In addition, the to-be-detected structure 371 or the detection component 372 is arranged in the first direction X of the carrier plate 320, which is conducive to reducing the space occupation in the second direction Y of the carrier plate 320, and facilitating to improve the space utilization of the driving motor 30 in the second direction Y of the carrier plate 320.

[0085] In some embodiments, with reference to FIG. 6, relative to the first magnet 331 and the second magnet 341 which need to form driving force, since the third magnet 373 and the fourth magnet 375 have smaller volumes, the third magnet 373 and the fourth magnet 375 can be arranged along the second direction Y, for example, arranged along the Y-axis direction in FIG. 6, thereby improving the space utilization of the driving motor 30.
