Exemplary, a lens control method for an electronic device to implement an auto-focus function includes:

s01: the processor responds to the automatic focusing instruction and sends a shot object acquisition signal to the camera module.

S02: the image pickup module is used for responding to the image pickup object obtaining signal, obtaining the image pickup object information and sending the image pickup object information to the processor.

S03: the processor determines the focusing position of the lens according to the shot object information, forms an automatic focusing driving signal capable of driving the lens to move to the focusing position, and sends the automatic focusing driving signal to a driving chip of the image pickup module.

S04: the driving chip of the camera module provides a first current for a focusing coil of the camera module according to the automatic focusing driving signal.

S05: the focusing coil which is electrified with the first current controls the movable part to drive the lens to move to the focusing position along the direction parallel to the optical axis. S06: the actual position of the movable part is obtained by the hall assembly and sent to the processor.

S07: the processor compares the actual position with the focusing position and judges whether the actual position and the focusing position are coincident, namely whether the lens moves to the preset focusing position.

Specifically, if the actual position coincides with the focusing position, indicating that the lens has moved to the preset focusing position at this time, ending the automatic focusing; if the actual position is not overlapped with the focusing position, the lens is not moved to the preset focusing position, an automatic focusing driving signal capable of driving the lens to move to the preset focusing position is formed according to the actual position of the movable part, and the automatic focusing driving signal is sent to a driving chip of the camera module. Steps S04 to S07 are executed again, and the process is repeated until the actual position coincides with the focusing position, that is, the lens moves to the preset focusing position, and the auto-focusing process is ended.

Exemplary, the lens control method for the electronic device to realize the super-stable video recording function comprises the following steps:

s11: the processor responds to the super-stable video recording instruction and sends a super-stable driving signal to the driving chip of the camera module.

S12: the driving chip supplies a second current to the focusing coil, and the focusing coil which is supplied with the second current drives the movable part to move to the bottom position. And then the driving chip supplies a third current to the focusing coil, and the focusing coil which is supplied with the third current controls the movable part to be kept at the bottom position.

S13: the energized focusing coil and auxiliary coil drive the movable part to move to the bottom position and keep the movable part at the bottom position.

In another possible implementation, the fixed portion includes a magnetic circuit assembly, and the movable portion includes a focusing coil and an auxiliary coil, the focusing coil and the auxiliary coil being in a magnetic field of the magnetic circuit assembly.

The control movable part drives the lens to move along the optical axis direction, comprising: providing a first current for the focusing coil so that the movable part drives the lens to move to a focusing position; controlling the movable part to move to the bottom position comprises providing a second current for the focusing coil and/or providing a third current for the auxiliary coil so as to enable the movable part to move to the bottom position; the control movable part is kept at the bottom position, and comprises: a fourth current is provided to the focusing coil and/or a fifth current is provided to the auxiliary coil to maintain the movable portion in the bottom position.

In the implementation mode, when the camera shooting module is in an automatic focusing working mode, the movable part can move along the optical axis direction under the action of the ampere force of the focusing coil and drive the lens to move to the focusing position, so that the electronic equipment realizes an automatic focusing function. When the camera module is in the super-stable working mode, the movable part is kept at the bottom position under the combined action of ampere force of the focusing coil and the auxiliary coil, and can provide larger pressing force for the movable part, so that the electronic equipment can realize the super-stable video recording function even in an unstable shooting environment, and a clear shooting effect is obtained.

For example, the method for controlling the lens of the electronic device to implement the auto-focusing function may refer to steps S01 to S07 described above.

S12: the driving chip of the camera module supplies current to the focusing coil and the auxiliary coil according to the super stable driving signal.

Specifically, in step S12, the driving chip supplies the second current to the focusing coil, supplies the third current to the auxiliary coil, and the focusing coil to which the second current is applied and the auxiliary coil to which the third current is applied drive the movable portion to move to the bottom position. And then the driving chip supplies a fourth current to the focusing coil, supplies a fifth current to the auxiliary coil, and controls the movable part to be kept at the bottom position by the focusing coil which is supplied with the fourth current and the auxiliary coil which is supplied with the fifth current.

In this implementation, the second current may have the same magnitude as the third current, the fourth current may have the same magnitude as the fifth current, and the second current may be greater than the fourth current. The focusing coil which is supplied with the fourth current is used for controlling the movable part to be kept at the bottom position, the power consumption can be reduced by using smaller current, the heating value of the coil is reduced, and the influence of the heating value on the lens is reduced. In other implementations, the second current and the fourth current may be the same magnitude.

In other implementations, the magnitudes of the second current and the third current may be different. For example, the second current is larger than the third current, and the focusing coil which is fed with the second current is used as a main driving component to drive the movable part to move to the bottom position. In other implementations, the speed of movement of the movable portion may be controlled by adjusting the magnitude of the third current.

In other implementations, the magnitudes of the fourth current and the fifth current may be different. For example, when the electronic device detects a severe shake, the fifth current is increased so that the movable portion is stabilized in the bottom position. In other implementations, the fifth current may also be a transient pulsed current.

In other implementations, the driving chip may only supply the second current and the fourth current to the focusing coil, and the movable portion is driven by the focusing coil to move toward and remain in the bottom position.

In still another possible implementation, the fixed portion includes a magnetic circuit assembly and an auxiliary coil, and the movable portion includes a focusing coil and an auxiliary magnetic circuit assembly, the focusing coil being in a magnetic field of the magnetic circuit assembly, and the auxiliary coil being in a magnetic field of the auxiliary magnetic circuit assembly.

In the implementation mode, when the camera module is in an automatic focusing working mode, under the action of the magnification force of the focusing coil, the movable part can move along the optical axis direction and drive the lens to move to the focusing position, so that the electronic equipment realizes the automatic focusing function. When the camera module is in the super-stable working mode, the movable part is kept at the bottom position under the combined action of ampere force of the focusing coil and the auxiliary coil. The electronic equipment can provide larger pressing force for the movable part, so that the electronic equipment can realize a super-stable video recording function even in an unstable shooting environment, and a clear shooting effect is obtained.

In one possible implementation manner, the camera module further includes a reed assembly, where the reed assembly connects the fixed portion and the movable portion, and the reed assembly is configured to stabilize the movable portion in the bottom position when the camera module is not energized. The reed assembly can also illustratively employ a conductive material to provide a current path for a coil mounted on the lens holder.

For example, when the camera module is not electrified, the elastic force generated by deformation of the reed assembly can provide pre-pressure to stabilize the movable part of the focusing motor at the bottom position. In an unstable shooting environment, the pre-pressure provided by the reed assembly is beneficial to enabling the lens to overcome inertia and keep at a far focus position, so that a clear shooting effect is obtained. In other implementations, the reed assembly may not deform and provide pre-compression, i.e., contact between the lens holder and the mount when the movable portion of the focus motor is in the bottom position, but no interaction force is generated.

In a possible implementation manner, the camera module further comprises an anti-shake motor, the anti-shake motor comprises an anti-shake fixing part and an anti-shake movable part, the focusing motor is arranged on the anti-shake movable part, and the anti-shake movable part can move or rotate relative to the anti-shake fixing part;

the lens control method further comprises the following steps: the camera shooting module responds to the automatic anti-shake driving signal and controls the anti-shake movable part to drive the lens to move or rotate relative to the anti-shake fixed part.

The middle part of the base 13 is provided with a through hole which penetrates the base 13 in a direction parallel to the optical axis 10. The filter 16 covers the through-hole. By way of example, the filter 16 may be Blue Glass (BG) for filtering infrared rays.

In some embodiments, please refer to fig. 2 and 3, wherein the camera module 1 further includes a driving chip (not shown), and the driving chip is configured to receive the driving signal from the processor 7 and convert the driving signal into a current for driving the focusing motor 12, and the focusing motor 12 drives the lens 11 to move under the driving of the current.

In the present application, the electronic device 100 has a plurality of photographing modes, such as a photographing mode, a recording mode, a super-stable recording mode, and the like. For easy understanding, the following embodiments of the present application will specifically describe embodiments of the two shooting functions on the electronic device 100 with reference to the drawings and application scenarios.

Fig. 4 is a schematic diagram of a graphical user interface (graphical userinterface, GUI) displayed by the display screen 2 when the electronic device 100 is in the unlock mode. The graphical user interface is the main interface of the electronic device 100, which is displayed on the display screen 2. In the present embodiment, the orientation in the graphical user interface near the earpiece 5 is defined as "up" and the orientation away from the earpiece 5 is defined as "down". It will be appreciated that references to "upper", "lower", etc. in this application are directional descriptions with reference to the attached drawings, and do not indicate or imply that the devices or elements being referred to must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the application.

The main interface displays icons of a plurality of third party applications (apps), such as a WeChat icon 302, a QQ icon 303, a settings icon 304, a camera icon 305, and a gallery icon 306. It will be appreciated that the host interface may also include icons for other and further applications, as this application is not strictly limited. In other embodiments, the camera icon 305 may also be displayed in the lock interface of the display screen 2 in the lock mode of the electronic device 100, which is not strictly limited in this application.

Fig. 5 is a schematic diagram of a graphical user interface in some embodiments when electronic device 100 is in a photographing mode. When the electronic device 100 detects a user's operation to click on the camera icon 305 shown in fig. 4, a camera application is started, displaying a graphical user interface as shown in fig. 5.

The graphical user interface of the camera application may include a viewfinder 307, an album icon 316, a capture control 317, and a camera rotation control 318. Wherein the preview image acquired by the camera module 1 is displayed in real time in the viewfinder 307. For example, an optical signal reflected by the subject enters the image capturing module 1 from the lens 11, passes through the optical filter 16, and is received by the photosensitive element 15. The photosensitive element 15 converts the optical signal into an electrical signal, and then transfers the electrical signal to the image signal processor. The image signal processor converts the electric signal output by the image pickup module 1 into a digital image signal, and forms preview image data after performing related processing on the digital image signal. The display screen 2 displays the preview image in real time in the viewfinder 307.

Illustratively, a schematic frame 308 of an autofocus area may be provided in the viewfinder 307. When the electronic apparatus 100 detects an operation of clicking a certain position of the viewfinder 307 in the screen 2 by the user, the clicked position corresponds to the indication of the schematic frame 308, and the electronic apparatus 100 performs automatic focusing with the position of the subject in the schematic frame 308 as the focus.

The shooting control 317 is used for shooting a photo or recording a video, and when the electronic device 100 detects that the user clicks the shooting control 317, the electronic device 100 executes a photo shooting program or a video recording program, and shoots or records the photo or the video recorded by the camera module 1, and stores the shot photo or the video recorded.

The album icon 316 is used to quickly enter the album, and when the electronic device 100 detects a user's click on the album icon 316, the saved photos and/or videos are presented on the display 2. The camera rotation control 318 is used to implement switching between the front camera and the rear camera.

Illustratively, a functional control for adjusting the image effect, such as a flash control 321, may be further provided above the viewfinder 307. In other embodiments, the effect function control may further include other function controls, such as an exposure time extension control, which is not limited in this embodiment of the present application.

Illustratively, a functional control for setting a shooting mode may be further provided below the viewfinder 307, for example: portrait mode control 311, video mode control 312, photo mode control 313, super stable video mode control 314, and more mode control 315. For example, after the electronic device 100 detects the operation of clicking the camera icon 305 in fig. 4, the camera module 1 and the display screen 2 are started to display the graphical user interface of the camera application, and at this time, the electronic device 100 defaults to the photographing mode. In other embodiments, the electronic device 100 may be in other modes by default, such as a video recording mode, which is not limited in the embodiments of the present application.

Illustratively, as shown in FIG. 5, when the electronic device 100 is in the photographing mode, the photographing mode control 313 is located above the photographing control 317 in the graphical user interface. It can be appreciated that when the electronic device 100 switches to other functional modes, the functional controls in the above modes correspondingly move to above the photographing control 317. In other embodiments, the photographing mode control 313 may also be differentiated from other functional controls by presenting different display states, so as to play a role in prompting the photographing mode corresponding to the interface where the user is located. For example, the color of the photographing mode control 313 is different from that of other functional controls, or the photographing mode control 313 is provided with a hatched area as shown in fig. 5, etc., which is not limited in the embodiment of the present application as long as it can be distinguished.

For example, referring to fig. 6, fig. 6 is a schematic diagram of a graphical user interface in some embodiments when the electronic device 100 is in a video recording mode. A portion of the graphical user interface shown in fig. 6 may be provided as described with respect to fig. 5, and may include, for example, a view box 307 and a capture control 317. The functional controls of shooting modes such as a video mode control 312, a super stable video mode control 314 and the like can be arranged below the view finder 307. An illustration frame 308 of an autofocus area may be provided in the viewfinder 307. A record duration icon 318 may also be displayed in the viewfinder 307, the record duration icon 318 being used to display the duration of the recorded video. Illustratively, when the electronic device 100 is in the video mode, the video mode control 312 is positioned above the capture control 317 in the graphical user interface.

For example, referring to fig. 7, fig. 7 is a schematic diagram of a graphical user interface of the electronic device 100 in a super stable video recording mode in some embodiments. A portion of the graphical user interface shown in fig. 7 may be provided as described with respect to fig. 5, and may include, for example, a view box 307 and a capture control 317. A functional control of a shooting mode such as a super-stable video mode control 314 may be provided below the view finder 307. A record duration icon 318 may also be displayed in the viewfinder 307, the record duration icon 318 being used to display the duration of the recorded video. Illustratively, when the electronic device 100 is in the super-stable video mode, the super-stable video mode control 314 is positioned above the capture control 317 in the graphical user interface.

Referring to fig. 8, fig. 8 is a schematic diagram of a graphical user interface of the electronic device 100 in a video recording mode in other embodiments. The graphical user interface of this embodiment is largely identical to that of the embodiment shown in fig. 6, and the main difference between them is that: in this embodiment, when the electronic device 100 is in the recording mode, the effect function control above the viewfinder 307 further includes a super stable recording control 322. When the electronic device 100 detects that the user clicks the super-stable video control 322, the electronic device 100 changes from the video mode to the super-stable video mode, and the schematic box 308 of the auto-focus area is no longer presented in the viewfinder 307.

In this embodiment, the electronic device 100 has an auto-focus function and a super-stable video recording function. The camera module 1 of the electronic device 100 has an auto-focus operation mode and a super-stable operation mode, wherein the auto-focus operation mode is used for supporting an auto-focus function of the electronic device 100, and the super-stable operation mode is used for supporting a super-stable video recording function of the electronic device 100. Referring to fig. 9, fig. 9 is a flowchart illustrating a method for implementing two photographing functions by the electronic device 100.

For example, the electronic device 100 may enter a photographing mode in response to a photographing instruction, activate the camera module 1, and send an autofocus driving signal to the camera module 1. For example, the electronic device 100 may also enter a video mode in response to a video command, activate the camera module 1, and send an autofocus driving signal to the camera module 1. The camera module 1 enters an auto-focus operation mode in response to the auto-focus driving signal, so as to support the electronic device 100 to implement an auto-focus function.

Among them, photographing instructions have various implementations. For example, the photographing instruction may be an operation of clicking the camera icon 305 of the graphical user interface in fig. 4 by the user detected by the electronic device 100 when the camera module 1 is not activated. The photographing instruction may also be an operation of clicking the photographing mode control 313 in the graphical user interface of the above mode by the user detected by the electronic device 100 when the photographing module 1 is in the start state and the electronic device 100 is in the non-photographing mode (for example, the video recording mode shown in fig. 6). In other embodiments, the photographing instruction may also be an operation detected by the electronic device 100 that the user clicks an icon or a control of the non-camera icon 305, for example, the user clicks a face identity information identification control in a graphical user interface of a payment device, the user clicks a video chat control in a graphical user interface of a WeChat, or the like. It will be appreciated that the photographing instruction may also be other operations of the user detected by the electronic device 100, such as voice control, mechanical key pressing action, etc., which are not limited in this embodiment of the present application.

Likewise, various implementations of the video command are possible, such as a video icon being triggered, an application calling, voice control, etc. The related description of the video recording instruction can refer to the photographing instruction, and will not be repeated here.

For example, as shown in fig. 9, when the camera module 1 is in the activated state, the electronic device 100 may further enter the super-stable video mode in response to the super-stable video command, and send a super-stable driving signal to the camera module 1. The camera module 1 enters a super-stable working mode in response to the super-stable driving signal, so as to support the electronic device 100 to realize a super-stable video recording function.

The super stable video command may have various embodiments. In some embodiments, the super-stable video recording instruction may be an operation of clicking the super-stable video recording mode control 314 in the graphical user interface of the above mode when the camera module 1 is in the start state and the electronic device 100 is in the non-super-stable video recording mode (such as the photographing mode shown in fig. 5 or the video recording mode shown in fig. 6).

For example, when the electronic device 100 is in the recording mode, the super-stable recording mode may be entered in response to the super-stable recording command, and a super-stable driving signal may be sent to the camera module 1. The camera module 1 enters a super-stable working mode in response to the super-stable driving signal to support the electronic device 100 to realize the super-stable video recording function.

The super-stable video recording command may be an operation of the super-stable video recording mode control 322 in a graphical user interface (as shown in fig. 8) of the video recording mode that is clicked by the user detected by the electronic device 100 when the electronic device 100 is in the video recording mode.

In the present application, the focusing motor 12 of the camera module 1 can support the camera module 1 to realize an auto-focusing operation mode and a super-stable operation mode. The specific structure of the focus motor 12 is described below with reference to the drawings. The present application describes the focusing motor 12 as a voice coil motor, but is not to be construed as limiting the embodiments of the present application.

By way of example, the magnetic circuit assembly 124 may be comprised of two magnets. In other embodiments, the magnetic circuit assembly 124 may be composed of one magnet, or may be composed of more than three magnets, which is not limited in this embodiment.

As shown in fig. 12, the movable unit 1202 includes a lens holder 127, a focusing coil 1261, and an auxiliary coil 1262. The movable part 1202 may include two sets of coils, each set including one focusing coil 1261 and one auxiliary coil 1262. The two sets of coils may be disposed on two opposite sides of the lens mount 127 in a central symmetrical manner to provide balanced support for the lens mount 127. It will be appreciated that the two sets of coils may be disposed on the outside of the lens holder 127 in other manners, such as mirror symmetry, as the embodiments of the present application are not limited in this respect.

Illustratively, as shown in FIG. 12, focus motor 12 further includes a reed assembly 125 and a Hall assembly 128.

In other embodiments, reed assembly 125 can also include one or more than three numbers of reeds, as this application is not strictly limited.

The hall assembly 128 is mounted between the fixed portion 1201 and the movable portion 1202. The hall module 128 is used for obtaining the actual position of the movable portion 1202, and the electronic device 100 can adjust the driving signal according to the actual position fed back by the camera module 1, so as to improve the accuracy of auto-focusing of the camera module 1.

Referring to fig. 13, fig. 13 is a schematic view of the structure of the support 122 shown in fig. 12. Wherein the support 122 may comprise a square bottom plate 1220 and four struts 1221. Four struts 1221 are fixed to four corners of the bottom plate 1220, respectively. The bottom plate 1220 and the four struts 1221 may be integrally formed.

Illustratively, as shown in fig. 13, a through hole 1270 penetrating the bottom plate 1220 in the optical axis direction is provided in the middle of the bottom plate 1220. Four support portions 1226 are provided around the through hole 1270 at intervals. Four support portions 1226 are located between the four posts and the through hole 1270.

Referring to fig. 14, fig. 14 is a schematic view of the structure of lower reed 1252 shown in fig. 12. Illustratively, lower reed 1252 can comprise two parts, which can be of symmetrical construction. One of the parts of lower reed 1252 can include a semicircular spring 1255 and two cantilevers 132, and the two cantilevers 132 are fixedly connected to different positions of the spring 1255, respectively. The single cantilever 132 may include a spring leg 1253 and a bending member 1254, the bending member 1254 being connected between the spring 1255 and the spring leg 1253. In other embodiments, lower reed 1252 can be integrally formed, for example, lower reed 1252 can include a circular ring-shaped spring plate and four cantilevers 132, wherein four cantilevers 132 are located around the spring plate in a dispersed manner, and one end of each cantilever 132 is fixedly connected to the spring plate. The specific structure of lower reed 1252 is not strictly limited in this embodiment.

For example, referring to FIG. 15, FIG. 15 is a schematic diagram of an assembled structure of mount 122 of FIG. 13 and lower reed 1252 of FIG. 14 in some embodiments. The side of the leg 1221 of the support 122 facing the through hole 1270 is provided with a receiving groove 1223. The sidewall of the receiving groove 1223 may be a cambered surface. Spring plate leg 1253 of lower spring plate 1252 is placed in accommodation groove 1223.

In other embodiments, the side wall of the receiving groove 1223 may also include a plurality of planes connected in sequence, which is not strictly limited in the embodiments of the present application. At this time, the shape of the spring pin 1253 can be adaptively changed according to the shape of the sidewall, so that the outer contour of the spring pin fits the sidewall of the accommodating groove 1223.

Illustratively, the strut 1221 is provided with a boss 1225 near the bottom of the base plate 1220. The boss 1225 has a limiting surface facing the accommodating groove 1223, and the spring pin 1253 may be fixed to the boss 1225 by being fixed to the limiting surface. Illustratively, the boss 1225 may be coupled to the base plate 1220 to increase the strength of the coupling of the strut 1221 to the base plate 1220. It is understood that the spring pin 1253 may be fixedly connected to the side wall of the accommodating groove 1223. In other embodiments, the strut 1221 may not have the boss 1225, and the spring pin 1253 is fixedly connected to the sidewall of the accommodating groove 1223. The specific connection structure between the spring pin 1253 and the base 122 is not strictly limited in the embodiment of the present application.

Referring to fig. 16, fig. 16 is a schematic view illustrating another view angle of the lens holder 127 shown in fig. 12. The view angle of the lens holder 127 shown in fig. 16 is inverted with respect to the view angle of fig. 12. The middle part of the lens bracket 127 is provided with a through hole 1270, and the through hole 1270 penetrates through the lens bracket 127 along the direction parallel to the optical axis 10. The lens holder 127 includes a first surface 1273 and four first protrusions 1271 secured to the first surface 1273. Four first protrusions 1271 are disposed around the through hole 1270 at intervals from each other. Two supporting pieces (1272 and 1275) are arranged on the side wall of the lens bracket 127, which faces away from the through hole 1270 in a staggered manner.

For example, referring to fig. 17, fig. 17 is a schematic diagram of an assembled structure of lens holder 127 of fig. 16 and lower reed 1252 of fig. 14 in some embodiments. The semicircular elastic piece 1255 of the lower reed 1252 is fixedly connected with the first surface 1273 of the lens holder 127, and is located inside the four first protrusions 1271 on the first surface 1273. Cantilever 132 of lower reed 1252 is interleaved with first boss 1271.

Referring to fig. 18, fig. 18 is a schematic diagram showing the structure of upper reed 1251 shown in fig. 12. Wherein upper reed 1251 comprises two semicircular ring shaped spring plates 1258.

Referring to fig. 19, fig. 19 is a schematic structural diagram of the lens holder 127 shown in fig. 12. Wherein, the lens holder 127 further comprises a second surface 1274, and the second surface 1274 is disposed opposite to the first surface 1273. Eight second protrusions 1275 are provided on the second surface 1274 at intervals along the edge of the second surface 1274. In other embodiments, other numbers of second protrusions 1275 may be provided on the second surface 1274, which is not strictly limited in the embodiments of the present application.

For example, referring to fig. 20, fig. 20 is a schematic diagram showing the assembled structure of lens holder 127 of fig. 19, lower reed 1252 of fig. 14, and upper reed 1251 of fig. 18 in some embodiments. Spring 1258 of upper reed 1251 is fixedly coupled to second surface 1274 of lens mount 127. Cantilever 131 of upper reed 1251 is arranged to be centrally symmetric around through hole 1270. Spring 1258 of upper reed 1251 is positioned inside eight second protrusions 1275 on second surface 1274, and protrusion 1259 of the end of spring 1258 is positioned between adjacent two second protrusions 1275. Second boss 1275 serves to define the mounting position of upper reed 1251, to improve the mounting accuracy and to reduce the mounting difficulty.

Illustratively, the upper reed 1251 and the lower reed 1252 each comprise two semicircular elastic pieces with the same shape, and each elastic piece is fixedly connected with two symmetrically arranged cantilevers, so that the elastic forces of the reeds along the direction of the cantilevers are the same, and the inclination and shaking of the lens support 127 fixedly connected to the reeds are avoided, and the shooting quality is influenced.

For example, referring to fig. 13 and 21, fig. 21 is a schematic diagram illustrating an assembled structure of the structure shown in fig. 20 and the support 122 shown in fig. 13 in some embodiments. The support 1221 of the support 122 has a recess 1222 facing away from the top of the base plate 1220, and the spring legs 1256 of the upper spring 1251 have mounting holes 1250. Illustratively, upper reed 1251 can be fixedly attached to column 1221 by screws passing through mounting holes 1250 and securing in recesses 1222. In other embodiments, upper reed 1251 can be fixedly attached to strut 1221 by riveting, bonding, welding, or the like, as embodiments of the present application are not limited in this regard. The shape of the spring plate leg 1256 of the upper spring plate 1251 can be the same as the top surface of the support 1221 facing away from the bottom plate 1220, so that the spring plate leg 1256 is completely attached to the top surface of the support 1221, and is firmly connected, and is not easy to separate when being subjected to a large tensile force.

For example, referring to fig. 16 and 21 together, the second surface 1274 of the lens holder 127 is disposed opposite to the bottom plate 1220 of the support 122, and the first surface 1273 is disposed opposite to the bottom plate 1220 of the support 122. Referring to fig. 21 and 22 together, fig. 22 is a schematic view of the structure of fig. 21 taken along the line D-D. Wherein the first boss 1271 of the lens holder 127 abuts the support 1226 on the bottom plate 1220 of the mount 122. The four first protrusions 1271 abut against the four supporting portions in a one-to-one correspondence. For example, the four first protruding portions 1271 and the four supporting portions are all distributed around the through hole 1270 in a central symmetry manner, so that the support 122 can provide a balanced supporting force for the lens support 127, and the lens support 127 can be more stably supported on the support 122 without shaking, so that an image with higher quality can be obtained. In other embodiments, other numbers of first protrusions 1271 and other numbers of supports 1226 may also be provided; the number of the first protrusions 1271 and the supporting portions 1226 may also be different, and the embodiment of the present application is not limited thereto, as long as the base 122 can provide support to the lens holder 127.

For example, referring to fig. 23, fig. 23 is a schematic diagram of a portion of the structure of the focus motor 12 shown in fig. 10. The focusing coil 1261 and the auxiliary coil 1262 can be sleeved on the supporting pieces (1272 and 1275) of the lens bracket 127 so as to be fixed on the lens bracket 127. For example, the coil may be wound around the lens holder 127 in the optical axis direction. At this time, the focusing coils 1261 and the auxiliary coils 1262 may be arranged up and down along the direction parallel to the optical axis 10, or may be stacked along the direction perpendicular to the optical axis 10, which is not strictly limited in the embodiment of the present application.

For example, referring to fig. 23 and 24, fig. 24 is a schematic view of the structure of fig. 23 taken along line C-C. The focusing coil 1261 and the auxiliary coil 1262 can be stacked, which is favorable for avoiding the inclination angle of the lens support 127 relative to the plane perpendicular to the optical axis 10, so that the lens support 127 shakes to influence the quality of the shooting picture. Therefore, the moving speed of the lens support 127 can be controlled by flexibly designing the current flowing into the focusing coil 1261 and the auxiliary coil 1262, so that the lens support is suitable for more application scenes. In other embodiments, the focusing coil 1261 and the auxiliary coil 1262 may be disposed in a staggered manner, for example, respectively sleeved on the support 1272 and the support 1275, which is not limited in the embodiment of the present application. In other embodiments, other numbers of support members, such as one or more than three, may be provided on the lens holder 127, which are not limited in this embodiment, so long as the coil is supported.

For example, the two sets of coils on both sides of the lens holder 127 may be arranged in the same manner, i.e. the focusing coils 1261 and the auxiliary coils 1262 in each set of coils are stacked or staggered. In other embodiments, the two sets of coils may be arranged differently, i.e. one set of coils has the focusing coil 1261 and the auxiliary coil 1262 stacked, and the other set of coils has the focusing coil 1261 and the auxiliary coil 1262 staggered, which is not limited in this embodiment.

For example, referring to fig. 23 and 25, fig. 25 is a schematic view of the structure shown in fig. 23 taken along line B-B. The hall assembly 128 includes a hall magnet 1281 and a hall coil 1282. Hall magnet 1281 is mounted on lens holder 127, hall coil 1282 is mounted on circuit board 123, and hall magnet 1281 and hall coil 1282 are disposed opposite to each other. In other embodiments, the hall magnet 1281 and the hall coil 1282 may be offset, so long as the hall coil 1282 is located in the magnetic field of the hall magnet 1281.

The hall assembly 128 is used for detecting the actual position of the lens holder 127 and feeding back, so that the focusing accuracy of the camera module 1 is improved. In other embodiments, the hall assembly 128 may not be provided, and embodiments of the present application are not strictly limited thereto.

Illustratively, the hall magnet 1281 may be mounted within the mounting slot 1276 of the lens mount 127 to reduce the occupation of the internal space of the motor 12, making the internal structure of the motor 12 more compact, thereby reducing the overall volume of the motor 12. In other embodiments, the hall magnet 1281 may be fixed on the outer side of the lens holder 127, which is not limited in this embodiment.

For example, referring to fig. 9 and 26 together, fig. 26 is a schematic view of the structure of fig. 10 taken along line A-A. Fig. 26 is a schematic structural view of the movable portion 1202 of the focus motor 12 in the bottom position. The lens 11 is mounted in the middle of the lens holder 127 of the movable part 1202. When the movable portion 1202 of the focus motor 12 is lowered to the bottom position, that is, when the movable portion 1202 is lowered to the allowable lowest position, the movable portion 1202 abuts against the fixed portion 1201. At this time, the first protrusion 1271 of the lens holder 127 abuts against the supporting portion 1226 of the base 122, and the lens 11 is in its telephoto position. The "far focus position" is a focus position when the lens 11 photographs an object located at infinity. The distance between the object and the lens 11 is greater than ten meters, and the object can be considered to be located at an infinite distance. When the lens 11 is at the "focusing position", an imaging surface formed by converging the object to be photographed through the lens 11 is located on the photosensitive surface of the photosensitive element 15.

Illustratively, reed assembly 125 connects stationary portion 1201 with movable portion 1202. The reed assembly 125 is used to stabilize the movable portion 1202 in the bottom position when the camera module 1 is not energized. In some embodiments, upper reed 1251 and lower reed 1252 are configured to provide an elastic force under which movable portion 1202 approaches or stabilizes in the bottom position. Illustratively, when camera module 1 is not energized, the elastic force generated by deformation of upper reed 1251 and lower reed 1252 can provide a pre-compression force to stabilize movable portion 1202 of focus motor 12 in the bottom position. Specifically, under the action of the pre-pressure force, there is an interaction force between the first convex portion 1271 of the lens holder 127 and the support portion 1226 of the mount 122. That is, support 1226 receives the pressure of first boss 1271, so that mount 122 is stabilized on lens holder 127 by the pre-pressure of upper reed 1251 and lower reed 1252.

In other embodiments, when camera module 1 is not energized, one of upper reed 1251 or lower reed 1252 can deform to create an elastic force, thereby providing a pre-pressure to stabilize movable portion 1202 of focus motor 12 in the bottom position. The other of upper reed 1251 or lower reed 1252 may not be deformed, and the embodiment of the present application is not limited thereto.

In addition, in an unstable environment, the elastic force generated by the deformation of upper reed 1251 and lower reed 1252 is beneficial to make lens 11 overcome inertia and keep in its far focus position, and obtain a clear shooting effect. Illustratively, when camera module 1 is energized, movable portion 1202 moves away from the bottom position, upper reed 1251 and lower reed 1252 deform to generate an elastic force that is used to return movable portion 1202 to the initial position to approach the bottom position.

In other embodiments, when the movable portion 1202 of the focusing motor 12 is in the bottom position, the first protrusion 1271 of the lens holder 127 and the supporting portion 1226 of the support 122 may also contact each other, but no interaction force is generated, which is not strictly limited in the embodiments of the present application.

For example, referring to fig. 11 and 26 together, upper reed 1251 and lower reed 1252 have one end connected to mount 122 of fixed portion 1201 and the other end connected to lens mount 127 of movable portion 1202, and function to carry movable portion 1202. In addition, the elastic force generated by upper reed 1251 and lower reed 1252 can buffer the movement of movable portion 1202, balance the moment, and improve the stability of lens 11. In some embodiments, upper reed 1251 and/or lower reed 1252 can employ a conductive material to provide a current path for a coil mounted on lens mount 127.

Illustratively, the magnetic circuit assembly 124 is fixed inside the housing 121 and disposed opposite the focusing coil 1261 and the auxiliary coil 1262. It will be appreciated that under the influence of the magnetic field of the magnetic circuit assembly, an ampere force is generated in the energized coil which moves it, the magnitude and direction of the ampere force being related to the magnitude and direction of the applied current. Therefore, in the present embodiment, after the focusing coil 1261 and the auxiliary coil 1262 are energized, an ampere force is generated to move the lens holder 127 in the direction parallel to the optical axis 10, and the lens holder 127 drives the lens 11 to move under the ampere force. In other embodiments, the magnetic circuit assembly 124 and the coil may be offset, so long as the coil is within the magnetic field of the magnetic circuit assembly 124.

The lens 11 is attached to the movable portion 1202, and the movable portion 1202 is movable relative to the fixed portion 1201 in a direction parallel to the optical axis 10 of the lens 10. The movable portion 1202 can be moved to the bottom position by the driving of the focusing coil 1261 and held at the bottom position. When the movable portion 1202 is held at the bottom position, the movable portion 1202 and the lens 11 are held stable with respect to the fixed portion 1201, and the lens 11 is at the telephoto position.

Illustratively, the movable portion 1202 includes a lens mount 127, a focusing coil 1261, and a secondary magnetic circuit assembly 1263. Wherein, the outside of the lens support 127 facing away from the through hole 1270 may be provided with a mounting groove, and the auxiliary magnetic circuit assembly 1263 is mounted in the mounting groove. The fixing portion 1201 includes an auxiliary coil 1262 and a support 122, and the auxiliary coil 1262 is mounted on the bottom plate 1220 of the support 122 and is disposed opposite the auxiliary magnetic circuit assembly 1263. It is understood that the mounting positions of the auxiliary magnetic circuit assembly 1263 and the auxiliary coil 1262 may be interchanged, i.e., the auxiliary coil 1262 is mounted outside the lens holder 127, and the auxiliary magnetic circuit assembly 1263 is mounted on the bottom plate 1220. In other embodiments, secondary magnetic circuit assembly 1263 and secondary coil 1262 may be offset so long as secondary coil 1262 is within the magnetic field of secondary magnetic circuit assembly 1263.

In addition, the secondary magnetic circuit assembly 1263 includes two magnets and is centrally symmetrically distributed about the through hole 1270. In this embodiment, the two auxiliary coils 1262 are distributed in a central symmetry manner, and the two magnets are distributed in a central symmetry manner, and the auxiliary coils 1262 are arranged opposite to the magnets, so that the energized auxiliary coils 1262 can provide balanced ampere force, the lens support 127 stably moves under the action of the ampere force, and the shake of the lens 11 mounted on the lens support 127 is reduced, so that the photographing quality is improved. In other embodiments, secondary magnetic circuit assembly 1263 may also include one or more than three numbers of magnets, as embodiments of the present application are not strictly limited thereto.

The auxiliary coil 1262 may be directly fixed to the bottom plate 1220, or may be indirectly fixed to the bottom plate 1220 through an intermediate medium. Illustratively, the circuit board 123 is positioned between the mount 122 and the lens mount 127 and is secured to a bottom plate 1220 of the mount 122. The auxiliary coil 1262 is fixed to the circuit board 123. The circuit board 123 includes a plurality of pins 1230 for making electrical connection with the exterior of the focus motor 12.

The body member 1231 is provided at its central portion with a through-hole 1270 penetrating the body member 1231 in a direction parallel to the optical axis 10. The body member 1231 is further provided with four fitting holes 1233 penetrating the body member 1231 in a direction parallel to the optical axis 10, the fitting holes 1233 being spaced around the through-hole 1270. The connector 1232 includes a plurality of pins 1230 disposed opposite the movable portion 1202. The auxiliary coil 1262 is mounted on the body member 1231 of the circuit board 123.

For example, referring to fig. 31, fig. 31 is a schematic diagram illustrating an assembled structure of the support 122 shown in fig. 29 and the circuit board 123 shown in fig. 30 in some embodiments. The mounting hole 1233 of the main body 1231 of the circuit board 123 is configured to avoid the supporting portion 1226 of the bottom plate 1220, so that the main body 1231 can be attached to the bottom plate 1220. The four legs of the support 122 are each provided with a baffle 1227 adjacent the bottom of the base plate 1220 for defining the mounting position of the body member 1231 to improve the assembly accuracy.

The present application also provides yet another embodiment of the focus motor 12. Referring to fig. 32, fig. 32 is an internal schematic view of the focusing motor 12 shown in fig. 3 in a third embodiment. The third embodiment may include most of the features of the first embodiment, and a brief description of the third implementation is provided below, and most of the content of the third implementation that is the same as that of the first implementation is not repeated.

The focus motor 12 includes a fixed portion 1201 and a movable portion 1202, the movable portion 1202 being located inside the fixed portion 1201. The lens 11 is attached to the movable portion 1202, and the movable portion 1202 is movable relative to the fixed portion 1201 in a direction parallel to the optical axis 10 of the lens 10. The movable portion 1202 can be moved to the bottom position and held in the bottom position by the driving of the focusing coil 1261. When the movable portion 1202 is held at the bottom position, the movable portion 1202 and the lens 11 are held stable with respect to the fixed portion 1201, and the lens 11 is at the telephoto position.

The stationary part 1201 includes a housing 121, a magnetic circuit assembly 124, a support 122, and a circuit board 123. The movable portion 1202 includes a lens holder 127 and a focusing coil 1261.

Wherein the focus motor 12 includes a focus coil 1261, and the function of the focus motor 12 is realized by the focus coil 1261. The main difference between this embodiment and the first embodiment is that the focus motor 12 is not provided with an auxiliary coil.

The application also provides a lens control method for realizing the automatic focusing function and the super-stable video recording function of the electronic device 100. The lens control method may be used for the electronic apparatus 100 including the focus motor 12, and the focus motor 12 may have a structure of any one of the three embodiments provided in the present application.

Exemplary, the lens control method includes: the camera module 1 responds to the automatic focusing driving signal and controls the movable part 1202 to drive the lens 11 to move along the direction parallel to the optical axis 10.

In the present embodiment, the lens control method enables the image capturing module 1 to control the lens 11 to move to its focusing position along the optical axis direction, so that the electronic device 100 achieves normal auto-focusing. In addition, the lens control method can enable the camera module 1 to control the movable part 1202 to sink to the bottom position and keep at the bottom position, so that the movable part 1202 keeps static relative to the fixed part 1201, and the lens 11 can overcome inertia to be stabilized at the far focus position, thereby realizing the ultra-stable effect similar to the fixed Jiao Mada, and therefore, the electronic device 100 in the ultra-stable video recording mode can have high-quality shooting effect even in an unstable shooting environment.

The method for implementing the automatic focusing working mode and the method for implementing the super-stable working mode of the camera module 1 can be various, and the specific method is designed according to the specific structure of the camera module 1.

Specifically, the process of controlling the movable part 1202 to move the lens 11 along the optical axis 10 by the camera module 1 includes: a first current is provided to the focusing coil 1261, so that the movable portion 1202 drives the lens 11 to move to the focusing position. The process of controlling the movable part 1202 to move to the bottom position by the camera module 1 includes: providing a second current to the focus coil 1261 and/or providing a third current to the auxiliary coil 1262 to move the movable portion 1202 to the bottom position; the process of controlling the movable portion 1202 to be held in the bottom position by the camera module 1 includes: a fourth current is provided to the focus coil 1261 and/or a fifth current is provided to the auxiliary coil 1262 to maintain the movable portion 1202 in the bottom position.

Illustratively, the reed assembly 125 of the camera module 1 can also be used to stabilize the movable portion 1202 in the bottom position when the camera module 1 is not energized. In this embodiment, when the camera module 1 is powered on, the reed assembly 125 provides a pre-pressure, and the movable portion 1202 is kept at the bottom position under the combined action of the pre-pressure of the reed assembly 125, the ampere force of the focusing coil 1261 and the auxiliary coil 1262.

The present application also provides another image capturing module 1 (see the second embodiment shown in fig. 27 to 31), which includes a fixed portion 1201 and a movable portion 1202. The stationary part 1201 includes the magnetic circuit assembly 124 and the auxiliary coil 1262, and the movable part 1202 includes the focusing coil 1261 and the auxiliary magnetic circuit assembly 1263.

The stationary part 1201 includes the magnetic circuit assembly 124 and the movable part 1202 includes the focusing coil 1261. Focusing coil 1261 is in the magnetic field of magnetic circuit assembly 124.

Specifically, the process of controlling the movable part 1202 to move the lens 11 along the optical axis 10 by the camera module 1 includes: a first current is provided to the focusing coil 1261, so that the movable portion 1202 drives the lens 11 to move to the focusing position.

It will be appreciated that the reed assembly 125 may not provide pre-compression, i.e., the movable portion 1202 may remain in the bottom position under the ampere force of the focusing coil 1261 when the camera module 1 is in the super-stable mode of operation.

In addition, in the present embodiment, the camera module 1 drives the movable portion 1202 to move through the focusing coil 1261, so that the electronic device 100 can realize the auto-focusing function and the super-stable video recording function, and compared with the first two embodiments, the auxiliary coil 1262 and other structures are omitted, the driving signal is simplified, and the power consumption and the heat productivity are reduced.

Specific processes for implementing the auto-focus function and the super-stable video recording function of the electronic device 100 are described below by way of example. The electronic device 100 may have a plurality of methods for implementing an auto-focusing function and a super-stabilizing function, and the specific method may be designed according to the specific structure of the camera module 1.

For example, referring to fig. 33, fig. 33 is a flowchart illustrating a lens control method for implementing an auto-focus function of the electronic device 100. The camera module of the electronic device 100 may adopt the structure of the first embodiment shown in fig. 10 to 26, the second embodiment shown in fig. 27 to 31, and the third embodiment shown in fig. 32, and the camera module further includes a driving chip electrically connected to the focusing coil 1261.

The lens control method for the electronic device 100 to realize the auto-focusing function includes:

s01: the processor 7 transmits a subject acquisition signal to the image capturing module 1 in response to the autofocus instruction.

S02: the image pickup module 1 acquires subject information in response to a subject acquisition signal, and sends the subject information to the processor 7.

S03: the processor 7 determines the focus position of the lens 11 from the subject information, forms an autofocus drive signal capable of driving the lens 11 to move to the focus position, and sends the autofocus drive signal to the drive chip of the image pickup module 1.

S04: the driving chip of the camera module 1 provides a first current to the focusing coil 1261 of the camera module 1 according to the auto-focusing driving signal.

S05: the focusing coil 1261 to which the first current is applied controls the movable portion 1202 to move the lens 11 to the focusing position along the direction parallel to the optical axis 10.

Specifically, the focusing coil 1261, to which the first current is applied, can move in a direction parallel to the optical axis 10 against the elastic force of the reed assembly 125 under the action of the ampere force, and drive the movable part 1202 of the focusing motor 12 to move. The lens 11 mounted on the movable portion 1202 also moves in a direction parallel to the optical axis 10 and moves to the in-focus position by the action of ampere force generated by the first current. The magnitude and direction of the first current can control the magnitude and direction of the ampere force, and thus control the parameters such as the displacement and speed of the movement of the movable portion 1202.

S06: the actual position of the movable portion 1202 is obtained by the hall assembly 128 and sent to the processor 7.

S07: the processor 7 compares the actual position with the focus position and determines whether the two coincide, i.e. whether the lens 11 is moved to the preset focus position.

Specifically, if the actual position coincides with the focusing position, which means that the lens 11 has moved to the preset focusing position, the automatic focusing is ended; if the actual position and the focus position do not coincide, indicating that the lens 11 is not moved to the preset focus position, an autofocus drive signal capable of driving the lens 11 to move to the preset focus position is formed according to the actual position of the movable portion 1202, and the autofocus drive signal is sent to the drive chip of the image capturing module 1. Steps S04 to S07 are executed again, and the auto-focusing process is ended until the actual position coincides with the focusing position, that is, the lens 11 moves to the preset focusing position.

Referring to fig. 34, fig. 34 is a flowchart illustrating a lens control method for implementing the super-stable video recording function of the electronic device 100. The camera module of the electronic device 100 may adopt the structure of the first embodiment shown in fig. 10 to 26 and the second embodiment shown in fig. 27 to 31.

The lens control method for the electronic device 100 to realize the super stable video recording function comprises the following steps:

s11: the processor 7 responds to the super-stable video recording instruction and sends a super-stable driving signal to the driving chip of the camera module 1.

S12: the driving chip of the camera module 1 supplies current to the focusing coil 1261 and the auxiliary coil 1262 according to the super stable driving signal.

S13: the energized focusing coil 1261 and auxiliary coil 1262 drive the movable portion 1202 to move to the bottom position and remain in the bottom position.

Specifically, in step S12, the driving chip supplies the second current to the focusing coil 1261, supplies the third current to the auxiliary coil 1262, and the focusing coil 1261 to which the second current is supplied and the auxiliary coil 1262 to which the third current is supplied drive the movable portion 1202 to move to the bottom position. The driving chip then supplies a fourth current to the focusing coil 1261, supplies a fifth current to the auxiliary coil 1262, and the focusing coil 1261 to which the fourth current is supplied and the auxiliary coil 1262 to which the fifth current is supplied control the movable portion 1202 to be kept in the bottom position.

The second current and the third current may have the same magnitude, the fourth current and the fifth current may have the same magnitude, and the second current may be greater than the fourth current. The focusing coil 1261 to which the fourth current is applied is used to control the movable portion 1202 to be kept at the bottom position, and the use of a smaller current can reduce power consumption, reduce the coil heating value, and reduce the influence of the heating value on the lens of the lens 11. In other embodiments, the second current and the fourth current may be the same in magnitude, which is not limited by the embodiments of the present application.

In other embodiments, the second current and the third current may be different in magnitude. For example, the second current is larger than the third current, and the focusing coil 1261 to which the second current is applied serves as a main driving member to move the movable portion 1202 to the bottom position. In other embodiments, the moving speed of the movable portion 1202 may be controlled by adjusting the magnitude of the third current, which is not strictly limited in the embodiments of the present application.

In other embodiments, the fourth current and the fifth current may be different in magnitude. For example, when the electronic apparatus 100 detects a severe shake, the fifth current is increased so that the movable portion 1202 is stabilized in the bottom position. In other embodiments, the fifth current may also be a transient pulse current, which is not strictly limited in the embodiments of the present application.

In other embodiments, the driving chip may only supply the second current and the fourth current to the focusing coil 1261, and the movable portion 1202 is driven by the focusing coil 1261 to move toward and remain in the bottom position.

In other embodiments, the camera module of the electronic device 100 may also adopt the structure of the third embodiment shown in fig. 32. The lens control method for the electronic device 100 to implement the super-stable video recording function corresponding to the image capturing module of the third embodiment can refer to the foregoing embodiments, and the main difference between the two is in step S12, in this embodiment, step S12 may be: the driving chip supplies a second current to the focusing coil 1261, and the focusing coil 1261 which is supplied with the second current drives the movable part 1202 to move to the bottom position. The driving chip then supplies a third current to the focusing coil 1261, and the focusing coil 1261 to which the third current is supplied controls the movable portion 1202 to remain in the bottom position.

In some embodiments of the present application, the camera module 1 may further have an optical anti-shake operation mode, and the electronic device 100 may further implement an optical anti-shake function. Wherein, camera module 1 can also include anti-shake motor. The anti-shake motor is used to drive the lens 11 to move in a direction perpendicular to the optical axis 10 or to rotate obliquely with respect to the optical axis 10.
