Detailed Description

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, a device configured to receive/transmit communication signals via a wireline connection and/or via a wireless communication network, such as a cellular network, a wireless local area network, or the like. Examples of mobile terminals include, but are not limited to, cellular telephones and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. The mobile phone is the electronic equipment provided with the cellular communication module.

Through long-term researches of the inventor, some mobile phones adopt only one spring plate type driving motor or only one ball type driving motor to realize displacement in the horizontal direction and the vertical direction simultaneously, and the spring plate type driving motor or the ball type driving motor is easy to damage when the displacement in two different directions is realized simultaneously.

In order to solve the technical problem, the embodiment of the application provides a novel anti-shake mechanism, a camera shooting module and electronic equipment. The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an electronic device provided in an embodiment of the present application, and fig. 2 is a schematic structural diagram of a camera module in the electronic device shown in fig. 1. The electronic device 1000 provided in the embodiment of the present application may be a portable device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device, and the following description will take the mobile phone as an example. As shown in fig. 1, the electronic device 1000 may include a housing 200, a camera module 400, and a display screen 600. The display screen 600 is disposed on the housing 200, and can be used for displaying a picture, and the camera module 400 can be disposed in the housing 200 and can receive light incident from the external environment to capture the picture.

The housing 200 may include a middle frame and a rear case, the display screen 600 may be covered on one surface of the middle frame, and the rear case is covered on the other surface of the middle frame. For example, the display 600 and the rear case may be covered on the opposite sides of the middle frame by bonding, welding, fastening, or the like. The camera module 400 may be disposed between the display screen 600 and the rear case, and may receive light incident from the external environment.

The rear case may be a battery cover of the electronic device 1000, and may be made of glass, metal, hard plastic, or other electrochromic materials. The rear case has a certain structural strength, and is mainly used for protecting the electronic device 1000. Correspondingly, the middle frame can also be made of glass, metal, hard plastic and the like. The middle frame also has a certain structural strength, and is mainly used for supporting and fixing the camera module 400 and other functional devices installed between the middle frame and the rear shell. Such as a battery, motherboard, antenna, etc. Further, since the middle frame and the rear shell are generally directly exposed to the external environment, the materials of the middle frame and the rear shell may preferably have a certain performance of wear resistance, corrosion resistance, scratch resistance, and the like, or the outer surfaces of the middle frame and the rear shell (that is, the outer surface of the electronic device 1000) are coated with a layer of functional material for wear resistance, corrosion resistance, scratch resistance.

The display screen 600 may include a display module, a circuit for performing a touch operation in response to the display module, and the like. The display screen 600 may be a screen using an OLED (Organic Light-Emitting Diode) or an LCD (Liquid Crystal Display ). The display screen 600 may be a flat screen, a hyperboloid screen, or a quadric screen in appearance, which is not limited in this embodiment. It should be noted that, for the mobile phone, the flat screen refers to that the display screen 600 is disposed in a flat shape as a whole; the hyperboloid screen is that the left and right edge areas of the display screen 600 are arranged in a curved shape, and other areas are still arranged in a flat plate shape, so that the black edge of the display screen 600 can be reduced, the visible area of the display screen 600 can be increased, and the appearance aesthetic feeling and the holding hand feeling of the electronic device 1000 can be increased; the four curved surface screen is that the upper, lower, left and right edge areas of the display screen 600 are all curved, and other areas are still flat, so that the black edge of the display screen 600 can be further reduced, the visible area of the display screen 600 can be increased, and the aesthetic feeling and the holding hand feel of the electronic device 1000 can be further increased.

In this embodiment, the camera module 400 may be used to implement functions of photographing, video recording, face recognition unlocking, code scanning payment, etc. of the electronic device 1000. Note that, the camera module 400 may be a rear camera as shown in the drawings, or may be a front camera, which is not limited in this embodiment. The structure of the camera module 400 is specifically described below with reference to the drawings.

As shown in fig. 2, the camera module 400 may include a housing 410, a first anti-shake mechanism 420, a lens 440, an image sensor 460, and a second anti-shake mechanism 480. Wherein, the first anti-shake mechanism 420, the lens 440, the image sensor 460, and the second anti-shake mechanism 480 are all disposed within the housing 410. The lens 440 is connected to the first anti-shake mechanism 420, and the first anti-shake mechanism 420 drives the lens 440 to move, so as to implement the lens anti-shake function of the camera module 400. The image sensor 460 is disposed opposite the lens in a direction parallel to the optical axis of the lens, and the image sensor 460 is connected to the second anti-shake mechanism 480. The second anti-shake mechanism 480 is disposed opposite to the first anti-shake mechanism 420 in a direction parallel to the optical axis of the lens 440, and the second anti-shake mechanism 480 is connected to the image sensor 460, where the second anti-shake mechanism 480 is used to drive the image sensor 460 to move in a direction perpendicular to the optical axis of the lens 440 or rotate around the optical axis of the lens 440, so as to implement an anti-shake function of the image sensor 460 of the camera module 400.

Specifically, the lens 440 may be made of glass or plastic. The lens 440 is mainly used to change the propagation path of light and focus the light. Lens 440 may include multiple sets of lenses that correct the filtered light for each other; when light passes through the lens 440, the multiple lens groups filter stray light (e.g. infrared light) layer by layer, so as to increase the imaging effect of the camera module 400. The image sensor 460 may be an image sensor such as a CCD (Charge Coupled Device ) or an image sensor such as a CMOS (Complementary Metal Oxide Semiconductor ). The image sensor 460 may be disposed opposite to the lens 440 in the optical axis direction of the camera module 400 (i.e. the optical axis direction of the lens 440, as shown by the dashed line in fig. 2), and is mainly configured to receive light collected by the lens 440 and convert the light signal into an electrical signal, so as to facilitate the implementation of the imaging requirement of the camera module 400.

It can be appreciated that the first anti-shake mechanism 420 and the second anti-shake mechanism 480 are mainly used for improving the imaging effect of the camera module 400 caused by shake of the user during the use process, so that the imaging effect of the image sensor 460 can meet the use requirement of the user. The camera module 400 of the embodiment of the application not only can realize the anti-shake of the lens 440, but also can realize the anti-shake of the image sensor 460, namely the camera module 400 of the embodiment of the application has a double anti-shake function.

In the related art, only a single anti-shake function such as camera anti-shake or image sensor anti-shake can be generally realized, however, the single anti-shake structure such as camera anti-shake or image sensor anti-shake is limited by the structural space limitation of the electronic device, and only a small-angle (such as within 1 ° or within 1.5 °) optical anti-shake function can be realized. The camera module 400 of this application embodiment can realize camera lens 440 anti-shake and image sensor 460 anti-shake simultaneously, and integrated camera lens 440 anti-shake function and image sensor 460 anti-shake function can realize the optics anti-shake of bigger angle for the correlation technique, effectively promotes the optics anti-shake effect of camera module 400.

Based on the optical anti-shake technology, the sensor such as a gyroscope or an accelerometer of the electronic device 1000 (or the camera module 400) may detect shake of the lens 440 to generate a shake signal, and transmit the shake signal to the electronic device 1000 and/or a processing chip of the camera module 400, where the electronic device 1000 and/or the processing chip of the camera module 400 may calculate a displacement amount that needs to be compensated by the first anti-shake mechanism 420, so that the first anti-shake mechanism 420 may compensate the lens 440 according to a shake direction of the lens 440 and a displacement amount thereof, thereby improving an imaging effect generated by shake of the camera module 400 generated during use of a user.

The specific structure of the first anti-shake mechanism 420 and its cooperation with other structural components of the camera module 400 are described in detail below.

Referring to fig. 3 to 4, fig. 3 is a schematic structural diagram of an anti-shake mechanism in the camera module shown in fig. 2, and fig. 4 is an exploded structural diagram of the anti-shake mechanism shown in fig. 2. The first anti-shake mechanism 420 may include a carrier assembly 421, a first driving assembly 422, and a second driving assembly 423. The bearing assembly 421 is used for bearing the lens 440, the first driving assembly 422 and the second driving assembly 423 are both disposed on the bearing assembly 421, and the first driving assembly 422 and the second driving assembly 423 are two driving assemblies with different structures. The first driving component 422 can drive the bearing component 421 to move along the direction parallel to the optical axis of the lens 440, and when the bearing component 421 moves along the direction parallel to the optical axis of the lens 440, the bearing component 421 can drive the lens 440 to move along the direction parallel to the optical axis of the lens 440 together so as to compensate the shake of the lens 440 along the direction parallel to the optical axis of the lens 440. The second driving component 423 can drive the bearing component 421 to move along the direction perpendicular to the optical axis of the lens 440, and when the bearing component 421 moves along the direction perpendicular to the optical axis of the lens 440, the bearing component 421 can drive the lens 440 to move along the direction perpendicular to the optical axis of the lens 440 together so as to compensate the shake of the lens 440 along the direction perpendicular to the optical axis of the lens 440.

Compared with the prior art that only one spring sheet type driving motor or one ball type driving motor is adopted to simultaneously realize displacement in the horizontal direction and the vertical direction, the driving assembly with two different structures is adopted to drive the bearing assembly in two different directions, so that the situation that part of components of the driving assembly are damaged due to the fact that the same driving assembly simultaneously realizes displacement in two different directions can be prevented, the anti-shake reliability of the first anti-shake mechanism 420 is improved, and the overall performance of the first anti-shake mechanism 420 is improved.

In addition, long-term researches of the inventor find that the spring sheet type driving motors of some mobile phones usually use a spring sheet structure and a hanging ring line structure to realize the displacement of the driving motors in the horizontal direction and the vertical direction so as to drive the displacement of the lens in the horizontal direction and the vertical direction, however, the problem that the spring sheet structure and/or the hanging ring line are broken easily occurs in the process of realizing the displacement in the horizontal direction; some ball-type driving motors of mobile phones generally adopt a plurality of balls to realize the displacement of the driving motor in the horizontal direction and the vertical direction so as to drive the displacement of the lens in the horizontal direction and the vertical direction, however, in the process of realizing the displacement in the vertical direction, the balls can mutually collide, so that a plurality of balls easily generate pits to cause the problem of unsmooth rolling.

Based on this, the first driving assembly 422 of the embodiment of the present application includes an elastic structure 4221, where the elastic structure 4221 is configured such that the elastic force can move the bearing assembly 421 in a direction parallel to the optical axis of the lens 440; the second driving assembly 423 includes a rolling structure 4231, and the rolling structure 4231 is configured to enable the bearing assembly 421 to move in a direction perpendicular to the optical axis of the lens 440 based on a rolling operation of the rolling structure 4231.

It can be appreciated that the first driving assembly 422 in the embodiment of the present application realizes the up-and-down movement of the bearing assembly 421 through the elastic structure 4221, and the second driving assembly 423 realizes the left-and-right movement of the bearing assembly 421 through the rolling structure 4231, so that, with respect to the related art, the problem that the elastic structure 4221 is easily broken due to being pulled in two mutually perpendicular directions, such as up-and-down movement and left-and-right movement, can be avoided, and the problem that the rolling structure 4231 is easily concave in the up-and-down movement process to cause unsmooth rolling can be avoided.

It should be noted that all directional indicators (such as up, down, left, right, front, and rear) in the embodiments of the present application are merely used to explain the relative positional relationship between the components, the movement situation, and the like in a certain specific posture, and if the specific posture is changed, the directional indicators are correspondingly changed.

As shown in fig. 4 and 5, fig. 5 is a schematic view of a first part of the anti-shake mechanism shown in fig. 3, where the carrier assembly 421 may include a first carrier 4211, a second carrier 4212, and a guide 4213, and the second carrier 4212 and the guide 4213 are disposed on the first carrier 4211. The first carrier 4211 may be a regular shape, for example, the first carrier 4211 may be a rectangular frame structure, which may have a first side 42111, a second side 42112, a third side 42113 and a fourth side 42114 connected in sequence, the first side 42111 and the third side 42113 being disposed opposite each other, and the second side 42112 being disposed opposite the fourth side 42114. The first carrier 4211 is further provided with a receiving space 42115, and the receiving space 42115 is defined by a first side 42111, a second side 42112, a third side 42113, and a fourth side 42114, which can receive a part of the devices of the first anti-shake mechanism 420. Of course, the first carrier 4211 may also be rounded rectangular or irregularly shaped.

The second carrier 4212 may be accommodated in the accommodating space 42115, and the second carrier 4212 may also be moved in the accommodating space 42115. The lens 440 may be disposed on the second carrier 4212, and the lens 440 may be driven to move when the second carrier 4212 moves. The second carrier 4212 may also be a rectangular frame structure, and may include a first support portion 42121, a second support portion 42122, a third support portion 42123, and a fourth support portion 42124 connected to each other, the first support portion 42121 and the third support portion 42123 being disposed opposite each other, and the second support portion 42122 being disposed opposite the fourth support portion 42124. The second carrier 4212 may be provided with a through hole 42125, and the lens 440 may be disposed through the through hole 42125 and fixed with a wall of the through hole 42125.

When the second carrier 4212 is received in the receiving space 42115, the first supporting portion 42121 is disposed opposite to the first side 42111, the second supporting portion 42122 is disposed opposite to the second side 42112, the third supporting portion 42123 is disposed opposite to the third side 42113, and the fourth supporting portion 42124 is disposed opposite to the fourth side 42114.

The guide 4213 is disposed on a portion of the first carrier 4211 in a stacked manner in a direction parallel to the optical axis of the lens 440 such that a portion of the first carrier 4211 is exposed outside the guide 4213. For example, the guide 4213 may comprise first and

second sides

42131, 42132 interconnected, which are generally "L" shaped in configuration. The first side 42131 can be layered on the first side 42111 and the second side 42132 can be layered on the second side 42112 such that the third side 42113 and the fourth side 42114 are exposed outside the guide 4213 or the third side 42113 and the fourth side 42114 are not layered with a portion of the guide 4213. Compared to the guide member 4213 with a rectangular structure in the related art, the guide member 4213 of the present embodiment may reduce the volume of the guide member 4213, thereby reducing the space occupation of the guide member 4213 on the first anti-shake mechanism 420, and facilitating the miniaturization of the first anti-shake mechanism 420.

As shown in fig. 4, the first anti-shake mechanism 420 may further include a magnetic assembly 424, and the magnetic assembly 424 may be a permanent magnet or an electromagnet, which may generate a magnetic field. Wherein the magnetic assembly 424 may be disposed on the carrier assembly 421, and the magnetic assembly 424 may include a plurality of magnetic members, each of which may include two magnets of opposite magnetic properties.

The first driving component 422 is located in the magnetic field generated by the magnetic component 424, and the first driving component 422 can drive the bearing component 421 to move along the direction parallel to the optical axis of the lens 440 under the action of the magnetic component 424. For example, the first driving component 422 may further include a first conductive member 4222, where the first conductive member 4222 is disposed opposite to the magnetic component 424 in a direction perpendicular to the optical axis of the lens 440, based on the fleming's left hand rule, a magnetic field may be generated after the first conductive member 4222 is energized, the magnetic field generated by the first conductive member 4222 may interact with the magnetic field of the magnetic component 424 to generate a first acting force (or magnetic acting force) perpendicular to the optical axis of the lens 440, the elastic structure 4221 may generate an elastic acting force perpendicular to the lens 440, and the first acting force and the elastic acting force act on the bearing component 421 at the same time, and the bearing component 421 may be driven by the first acting force and the elastic acting force to move up and down, so as to drive the lens 440 to move up and down, so as to implement auto-focusing of the lens 440 and/or compensate for shake of the lens 440 in the vertical direction.

For example, referring to fig. 4 and 5, the first driving assembly 422 may include two first conductive members 4222, where the two first conductive members 4222 are disposed on two sides of the second carrier 4212 in a direction perpendicular to the optical axis of the lens 440, for example, one first conductive member 4222 may be disposed on the first supporting portion 42121, and the other first conductive member 4222 may be disposed on the third supporting portion 42123. The structures of the two first conductive members 4222 may be the same, for example, the two first conductive members 4222 may be annular structures as shown in fig. 5, the first supporting portion 42121 and the third supporting portion 42123 may be provided with a limiting structure, one first conductive member 4222 may be clamped on the limiting structure of the first supporting portion 42121, and the other first conductive member 4222 may be clamped on the limiting structure of the third supporting portion 42123. Of course, the two first conductive members 4222 may have a single rod structure or a double rod structure. In some embodiments, the two first conductive members 4222 may also be different in structure, for example, one first conductive member 4222 may be a ring structure, the other first conductive member 4222 may be a single-rod structure or a double-rod structure, etc.

The magnetic assembly 424 may include a first magnetic member 4241, a second magnetic member 4242, and a third magnetic member 4243, and the first magnetic member 4241, the second magnetic member 4242, and the third magnetic member 4243 may be disposed on the first carrier 4211.

For example, referring to fig. 6 to 8, fig. 6 is a schematic structural diagram of a first carrier in the anti-shake mechanism shown in fig. 4, fig. 7 is a schematic structural diagram of a second part of the anti-shake mechanism shown in fig. 3, and fig. 8 is a schematic structural diagram of a third part of the anti-shake mechanism shown in fig. 3. The first carrier 4211 is provided with a first receiving groove 42116a, a second receiving groove 42116b, and a third receiving groove 42116c, the first receiving groove 42116a being provided on the first side 42111, the second receiving groove 42116b being provided on the third side 42113, and the third receiving groove 42116c being provided on the fourth side 42114. The first magnetic member 4241 is disposed in the first receiving groove 42116a and is disposed opposite to one first conductive member 4222 in a direction perpendicular to an optical axis of the lens 440 such that one first conductive member 4222 is located within a magnetic field generated by the first magnetic member 4241, and one first conductive member 4222 may generate a magnetic field when energized and interact with the magnetic field generated by the first magnetic member 4241 and generate a pushing force to the second carrier 4212.

Wherein the first magnetic member 4241 may comprise a first magnet 42411 and a second magnet 42412, the magnetic properties of the first magnet 42411 being opposite to the magnetic properties of the second magnet 42412, such as the first magnet 42411 may be a south pole and the second magnet 42412 may be a north pole; or the first magnet 42411 may be a north pole and the second magnet 42412 may be a south pole. And the first magnet 42411 and the second magnet 42412 are stacked in a direction parallel to the optical axis of the lens. A portion of one first conductive member 4222 is disposed opposite to the first magnet 42411, and a portion of one first conductive member 4222 is disposed opposite to the second magnet 42412. Taking the first conductive member 4222 as an example of a ring structure, the first conductive member 4222 may include a first portion and a second portion disposed along a direction perpendicular to an optical axis of the lens 440, the first portion being disposed opposite to the first magnet 42411, and a third portion and a fourth portion disposed along a direction parallel to the optical axis of the lens 440, the second portion being disposed opposite to the second magnet 42412.

The second magnetic member 4242 is disposed in the second receiving groove 42116b, and is disposed opposite to the other first conductive member 4222 in a direction perpendicular to the optical axis of the lens 440. So that the other first conductive member 4222 is located in the magnetic field generated by the second magnetic member 4242, the other first conductive member 4222 can generate a magnetic field when energized, interact with the magnetic field generated by the second magnetic member 4242, and generate a pushing force on the second carrier 4212, and the second carrier 4212 moves up and down relative to the first carrier 4211 under the pushing force exerted by the two second conductive members and the elastic force generated by the elastic structure.
