The electronic device 1000 may include a camera mechanism 100, a display screen 200, and a housing 300. The display screen 200 and the housing 300 are connected and enclosed to form an accommodating space 1001. The accommodating space 1001 may be used to provide structural members such as the camera mechanism 100, a motherboard, and a battery, so that the electronic device 1000 can implement corresponding functions. The display screen 200, the camera mechanism 100 and other structural components can be respectively electrically connected with a main board, a battery and the like through a Flexible Printed Circuit (FPC), so that they can obtain the power supply of the battery, and can execute corresponding instructions under the control of the main board. Based on this, the camera mechanism 100 may be located at one side of the display screen 200 and configured to collect light outside the electronic device 1000 (hereinafter, referred to as external light).

It should be noted that: taking the electronic device 1000 such as a mobile phone as an example, the camera mechanism 100 can be used for realizing front-facing camera shooting of the electronic device 1000, and can also be used for realizing rear-facing camera shooting of the electronic device 1000. That is, the camera mechanism 100 may be a front-mount type or a rear-mount type. The front camera shooting can be performed by the camera mechanism 100 receiving light near the display screen 200 for imaging, and the rear camera shooting can be performed by the camera mechanism 100 receiving light far away from the display screen 200 for imaging.

The display screen 200 may be used to provide an image display function for the electronic device 1000, and when the user uses a shooting function of the electronic device 1000, the display screen 200 may present an imaging picture of the camera mechanism 100 for the user to observe and operate. The display screen 200 may include a transparent cover plate, a touch panel, and a display panel, which are sequentially stacked. The surface of the transparent cover plate can have the characteristics of flatness and smoothness, so that a user can conveniently perform touch operation such as clicking, sliding and pressing. The transparent cover plate may be made of rigid material such as glass, or may be made of flexible material such as Polyimide (PI) and Colorless Polyimide (CPI). The touch panel is disposed between the transparent cover plate and the display panel, and is configured to respond to a touch operation of a user, convert the touch operation into an electrical signal, and transmit the electrical signal to the processor of the electronic device 1000, so that the electronic device 1000 can make a corresponding response to the touch operation of the user. The display panel is mainly used for displaying pictures and can be used as an interactive interface to instruct a user to perform the touch operation on the transparent cover plate. The Display panel may employ an OLED (Organic Light-Emitting Diode) or an LCD (Liquid Crystal Display) to implement the image Display function of the electronic device 1000.

The accommodating space 1001 may be used to mount electronic devices such as an optical sensor, so as to achieve functions such as fingerprint unlocking, automatic screen turning off, brightness self-adjustment, and the like. The accommodating space 1001 may also be used to mount electronic devices such as a microphone, a speaker, a flash, a circuit board, and a battery, so as to implement functions such as voice communication, audio playing, and illumination.

It can be understood that: all directional indications (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly.

Referring to fig. 2, fig. 2 is an exploded view of a camera mechanism in an electronic device in the related art. The camera mechanism 100 is accommodated in the accommodating space 1001 and can collect light outside the accommodating space 1001. The camera mechanism 100 may include a base 10, a camera module 20, and a drive assembly 90. The base 10 may be used to fixedly mount the camera mechanism 100 in the accommodating space 1001, and the base 10 may be provided with an accommodating groove 101. The camera module 20 can be accommodated in the accommodating groove 101, and the driving assembly 90 is supported on the camera module 20. In an embodiment, the driving element 90 can be disposed around the outer periphery of the camera module 20 and can be used to drive the camera module 20 to move. The driving assembly 90 may be a structural member driven by electromagnetic force, piezoelectric ceramic, memory alloy, or electrostatic force, for example, the driving assembly 90 may be a structural member of a voice coil motor driven by electromagnetic force.

It should be noted that: the driving component 90 in the present application may enable the camera mechanism 100 to implement one or a combination of Auto Focus (AF), Optical Image Stabilization (OIS), and other functions. Based on the optical anti-shake technology, the gyroscope of the electronic device 1000 (or the camera mechanism 100) detects a slight shake of the lens group 21, and the gyroscope further transmits a shake signal to the microprocessor to calculate a displacement amount that the driving element 90 needs to compensate, so that the driving element 90 compensates the lens group 21 according to the shake direction and the displacement amount of the camera module 20, thereby improving unstable imaging of the camera mechanism 100 caused by shake of a user during use.

Applicants have discovered in their research that a drive assembly 90, such as a voice coil motor, is typically implemented by translating the camera module 20 in order to achieve optical anti-shake. However, during the translation of the camera module 20, the optical axes of the lens group 21 and the image sensor 222 may change, thereby affecting the quality of the captured image. In addition, the lens group 21 can change the angle of view in the process of moving horizontally and preventing shake, so that the four corners of the image can shake obviously in the process of shooting the image, and the imaging effect is poor.

Based on this, the applicant has proposed a camera mechanism 100 through many experiments, so as to better avoid the above technical problems in the process of implementing the anti-shake of the lens group 21.

Specifically, the base 10 is accommodated and fixedly installed in the accommodating space 1001, that is, the base 10 can be fixedly connected to the display screen 200 and/or the housing 300 by means of screwing, inserting, snapping, welding, bonding, and the like, so that the camera mechanism 100 is fixedly connected to the display screen 200 and/or the housing 300.

Optionally, a light hole 110 is disposed on the substrate 11, so that the light passing through the lens set 21 can pass through the light hole 110 of the substrate 11.

Referring to fig. 3 and 4, the camera module 20 may include not only the lens set 21, but also the photosensitive module 22. In this embodiment, the lens set 21 in the camera module 20 can be suspended in the accommodating groove 101, and the photosensitive module 22 is fixedly connected to the base 10, so that the lens set 21 can rotate relative to the base 10 and the photosensitive module 22 to implement the OIS function of the camera mechanism 100.

Specifically, the filter 221 may be disposed between the lens group 21 and the image sensor 222, and the filter 221 is mainly used for filtering infrared light to increase the imaging effect of the camera mechanism 100. The image sensor 222 can be mainly used for receiving light from the lens group 21 and converting the light signal into an electrical signal, so as to meet the imaging requirement of the camera mechanism 100. That is, the image sensor 222 may be configured to convert an optical signal collected by the lens group 21 into an electrical signal. Wherein, the external light can sequentially pass through the lens set 21 and the filter 221 to act on the image sensor 222.

It is understood that since the wiring board 223 is fixedly connected to the substrate 11 and the image sensor 222 is fixed on the wiring board 223, the image sensor 222 is stationary relative to the base 10. Since the optical filter 221 and the image sensor 222 are stationary relative to the base 10, the rotation of the lens set 21 relative to the base 10 can be regarded as the rotation of the lens set 21 relative to the photosensitive module 22, so that when the OIS function of the camera mechanism 100 is performed, the optical axis between the lens set 21 and the image sensor 222 can be prevented from changing or slightly changing, and meanwhile, the angle of view can be prevented from changing or slightly changing, thereby improving the imaging effect.

It is understood that the anti-shake assembly 40 and the magnetic member 32 are provided on one of the base 10 and the lens group 21, and the magnet 31 is provided on the other of the base 10 and the lens group 21. In other words, the anti-shake assembly 40 is located on the base 10 or the lens group 21 where the magnetic member 32 is located.

The magnet 31 may be a permanent magnet (having a magnetic field), and the magnetic member 32 may be a structural member including a ferromagnetic material such as iron, nickel, or cobalt. The magnetic field of the magnet 31 can act on the magnetic member 32 to generate an attraction force or a repulsion force acting on the magnetic member 32, so that the lens group 21 can be suspended in the accommodating groove 101. Of course, in some embodiments, the magnet 31 may be a coil and/or the magnetic member 32 may be a coil that, when energized, may generate a magnetic field, thereby generating an attractive or repulsive force between the magnet 31 and the magnetic member 32.

Referring to fig. 7 and 8 in combination: the number of the magnets 31, the magnetic members 32, and the coils is not limited to the above-mentioned number, and may be other numbers. For example, the magnets 31 may be provided in three numbers, and the three magnets 31 are uniformly distributed on the base 10 and are symmetrical with respect to the optical axis of the lens group 21. In addition, the magnets 31 may be disposed in one-to-one correspondence with the magnetic members 32, and/or the magnets 31 may be disposed in one-to-one correspondence with the coils, i.e., the number of the magnetic members 32 and the coils is not limited to be the same or not.

It should be noted that the terms "first", "second" and "third" in the embodiments of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

In one embodiment, the magnets 31 and the magnetic members 32 are disposed in a one-to-one correspondence, and the magnets 31 and the magnetic members 32 are disposed at intervals, at this time, the magnetic force between the magnets 31 and the magnetic members 32 acts on the lens group 21, and the lens group 21 is suspended in the accommodating groove 101 of the base 10.

In one embodiment, the magnets 31 may be disposed in one-to-one correspondence with the magnetic members 32, a portion of the corresponding magnetic members 32 is in contact with the magnets 31, and another portion of the corresponding magnetic members 32 is spaced apart from the magnets 31. The first magnetic force and the second magnetic force are not necessarily the same in magnitude, subject to certain differences in the structure itself and assembly tolerances. When the first magnetic force and the second magnetic force are different in magnitude, the magnetic member 32 on one side is attracted to the corresponding magnet 31, and the magnetic member 32 on the other side is spaced from the corresponding magnet 31. And so on, in other embodiments, the magnetic member 32, which may be one side or adjacent sides, may be attracted to the corresponding magnet 31, and the magnetic members 32 on the remaining sides may be spaced from the corresponding magnet 31. At this time, the lens set 21 can be suspended in the receiving cavity 101.

It can be understood that, based on the ball structure of the magnetic member 32 and the arc/spherical structure of the mounting surface 201, the attracting contact between the magnetic member 32 and the magnet 31 is substantially in a point-contact state, i.e., the contact surface between the base 10 and the lens group 21 is extremely small, so as to greatly reduce the friction force when the lens group 21 rotates relative to the base 10, and ensure that the OIS function is well performed.

Referring to fig. 4 and 5, the anti-shake assembly 40 may further include a plurality of anti-shake sensors 42, and the anti-shake sensors 42 are respectively disposed adjacent to the anti-shake coils 41 in a one-to-one correspondence manner. Each anti-shake sensor 42 is disposed on the base 10 or the lens group 21 where the anti-shake coil 41 is located, and is configured to measure the magnetic field strength and the magnetic field direction of the magnet 31 corresponding to the anti-shake coil 41, and further determine the position and the deflection angle of the optical axis of the lens group 21 relative to the base 10, so as to facilitate the camera mechanism 100 to accurately control the angle and the position of the lens group 21 in the accommodating groove 101, and further accurately adjust the position and the angle of the lens group 21 in the accommodating groove 101, thereby implementing the anti-shake function of the camera mechanism 100.

Alternatively, the anti-shake assembly 40 cooperates with the magnet 31 to apply a force to the lens group 21 in the direction of the optical axis of the lens group 21, and the force can drive the lens group 21 to rotate relative to the base 10, so that the optical axis between the lens group 21 and the image sensor 222 can always be kept consistent, thereby implementing the OIS function of the camera mechanism 100.

The camera mechanism 100 provided by the embodiment of the present application, the magnetic member 32 and the magnet 31 are arranged to cooperate with each other to suspend the lens set 21 in the accommodating groove 101, and the magnet 31 and the anti-shake assembly 40 are arranged to cooperate with each other to drive the lens set 21 to rotate relative to the base 10, so that when the OIS function of the camera mechanism 100 is executed, the optical axis between the lens set 21 and the image sensor 222 can be prevented from changing or slightly changing, and meanwhile, the view angle can be prevented from changing or slightly changing, thereby improving the imaging effect.
