As shown in fig. 1, the electronic device 100 may include a housing 10, a camera module 20, and a display screen 30. The display screen 30 is disposed on the housing 10, and can be used for displaying a picture, and the camera module 20 can be disposed on the housing 10 and can receive light emitted from an external environment to capture the picture.

The camera module 20 may include a base 21, a lens 22, a carrying assembly 23, a first driving assembly 24, a photosensitive element 25 and an anti-shake module 26. The base 21 is provided with an installation space 211, the bearing assembly 23 and the first driving assembly 24 are arranged in the installation space 211 of the base 21, the lens 22 is arranged on the bearing assembly 23, and the bearing assembly 23 is driven by the first driving assembly 24 to move along a direction perpendicular to an optical axis of the lens 22, so that the lens 22 can be driven to move to realize an anti-shake function of the lens 22 of the camera module 20. The light sensing element 25 is disposed at one side of the anti-shake module 26 and is disposed opposite to the lens 22 in a direction parallel to the optical axis of the lens 22, and the light sensing element 25 can convert the acquired optical signal into an electrical signal. The anti-shake module 26 is connected to the photosensitive element 25, and the anti-shake module 26 is used for driving the photosensitive element 25 to move in a plane perpendicular to the optical axis of the lens 22, so as to realize the anti-shake function of the photosensitive element 25 of the camera module 20. In this way, the dual anti-shake of the photosensitive element 25 and the lens 22 is realized by providing the anti-shake module 26 and the first driving component 24. In this embodiment, the camera module 20 may be used to implement functions of the electronic device 100, such as photographing, recording, unlocking by face recognition, and code scanning payment. In addition, the camera module 20 may be a rear-view camera or a front-view camera, which is not limited in this embodiment.

Specifically, the lens 22 may be made of glass or plastic. The lens 22 is mainly used to change the propagation path of light and focus the light. Lens 22 may include multiple sets of lenses that collimate and filter light; so that the lens layers filter stray light (e.g., infrared light) when the light passes through the lens 22, so as to increase the imaging effect of the camera module 20. The photosensitive element 25 may be an image sensor such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). The photosensitive element 25 can be disposed opposite to the lens 22 in an optical axis direction of the camera module 20 (i.e., the optical axis direction of the lens 22), and is mainly used for receiving light collected by the lens 22 and converting an optical signal into an electrical signal, so as to meet an imaging requirement of the camera module 20. The anti-shake module 26 and the first driving assembly 24 are mainly used to improve the imaging effect of the camera module 20 caused by the shake of the user during the use process, so that the imaging effect of the photosensitive element 25 can meet the use requirements of the user.

Based on the optical anti-shake technology, a sensor such as a gyroscope or an accelerometer of the electronic device 100 (or the camera module 20) may detect shake of the lens 22 to generate a shake signal, and transmit the shake signal to a processing chip of the electronic device 100 and/or the camera module 20, the processing chip of the electronic device 100 and/or the camera module 20 may calculate a displacement amount that the anti-shake module 26 and the first driving component 24 need to compensate, so that the first driving component 24 may compensate the lens 22 according to a shake direction of the lens 22 and the displacement amount thereof, and the anti-shake module 26 may compensate the photosensitive element 25 according to a shake direction of the photosensitive element 25 and the displacement amount thereof, thereby improving an imaging effect of the camera module 20 caused by shake of a user during use.

It should be noted that, in the related art, some mobile terminals employ dual driving mechanisms to respectively control the movement of the lens and the photosensitive chip, so as to achieve the anti-shake of the lens and the anti-shake of the photosensitive chip. The dual-drive mechanism is usually disposed in the base, and when the dual-drive mechanism works, the dual-drive mechanism is easy to interfere with each other.

Based on this, please refer to fig. 5 in combination with fig. 3, and fig. 5 is a schematic structural diagram of the base, the anti-shake module and the photosensitive element in fig. 3. The camera module 20 provided in the embodiment of the present application, the bearing assembly 23 and the first driving assembly 24 for anti-shake of the lens 22 are disposed in the installation space 211 of the base 21, and the anti-shake module 26 for anti-shake of the photosensitive element 25 is disposed outside the installation space 211 of the base 21, that is, the bearing assembly 23 and the first driving assembly 24 are located in different spaces from the anti-shake module 26, and a relatively independent movement space is provided therebetween, so that the first driving assembly 24, the bearing assembly 23, and the anti-shake module 26 do not intersect or overlap in the movement process, thereby avoiding interference between some elements in the camera module 20, such as avoiding interference between the anti-shake module 26, the first driving assembly 24, and the bearing assembly 23. When the anti-shake module 26 drives the photosensitive element 25 to move, the photosensitive element 25 does not interfere with the first driving assembly 24 or the carrying assembly 23.

It should be further noted that, in the related art, because the dual-driving mechanism is usually disposed in the base, in order to solve the interference problem, the size of the base is usually required to be increased to have a larger accommodating space for the dual-driving mechanism to move under the condition of mutual noninterference, and the size of the camera module mainly depends on the size of the base, so that the size of the camera module is increased.

The camera module 20 provided in the embodiment of the present application, through setting the anti-shake module 26 outside the installation space 211 of the base 21, so that the interference between the anti-shake module 26 and the components in the base 21 can be avoided, such as the interference between the anti-shake module 26 and the first driving component 24 and the bearing component 23 in the base 21 is avoided, and it is not necessary to increase the size of the base 21 specially in order to prevent the interference between the anti-shake module 26 and other components in the base 21, so that the overall size of the base 21 can be made smaller, and the miniaturized design of the camera module 20 is realized. Moreover, the independent design of the anti-shake module 26 facilitates the independent model selection and the independent assembly of the anti-shake module 26, and the practicability is higher.

It is understood that the anti-shake module 26 is disposed outside the installation space 211, and may be connected to the base 21 or other components of the camera module 20. Referring to fig. 6 and 7 in combination with fig. 5, fig. 6 is a schematic structural diagram of the anti-shake module and the photosensitive element in fig. 5, and fig. 7 is a schematic structural diagram of the anti-shake module in fig. 6. The anti-shake module 26 may include an upper bracket 261, a lower bracket 262 and a driving member 263, where the upper bracket 261 is connected to the base 21, and is connected to the base 21 through the upper bracket 261 to implement the anti-shake module 26 being disposed outside the installation space 211 of the base 21. The lower frame 262 is located on one side of the upper frame 261 facing the photosensitive element 25, the photosensitive element 25 is fixedly disposed on the lower frame 262, and the driving member 263 connects the upper frame 261 and the lower frame 262, so that the driving member 263 can drive the lower frame 262 to move in the direction perpendicular to the optical axis of the lens 22 relative to the upper frame 261, and further drive the photosensitive element 25 to move in the direction perpendicular to the optical axis of the lens 22, so as to compensate the shake of the photosensitive element 25 in the direction perpendicular to the optical axis of the lens 22, and thus to prevent the shake of the photosensitive element 25.

It is to be understood that, in order not to obstruct the light from being incident on the photosensitive element 25, the upper support 261 and the lower support 262 are each provided with a light-transmitting hole for the light to be incident on the photosensitive element 25, and the light signal obtained is converted into an electrical signal by the photosensitive element 25.

It should be noted that, in the related art, when the anti-shake module for driving the photosensitive element to move drives the photosensitive element to move, a part of the photosensitive element can extend into the light hole of the anti-shake module, and the light hole is easily interfered with the hole wall of the light hole in the anti-shake module.

Based on this, in the camera module 20 that this application embodiment provided, photosensitive element 25 can include fixed plate 251 and the photosensitive chip 252 that is used for converting light signal into the signal of telecommunication, photosensitive chip 252 sets up in fixed plate 251, fixed plate 251 is fixed in the one side that deviates from upper bracket 261 in lower carriage 262, thus, in the in-process that lower carriage 262 removed, photosensitive element 25 then can not take place to interfere with upper bracket 261, this application is through the position that sets up of design photosensitive chip 252, thereby need not to increase the volume of upper bracket 261 and can avoid photosensitive chip 252 and upper bracket 261 to take place to interfere, so, compare in correlation technique, the volume of the anti-shake module 26 of this application can design littleer, realize camera module 20's miniaturized design.

It can also be understood that the photosensitive element thus configured will not interfere with the bearing assembly 23 or the first driving assembly 24 in the base when driven to move by the anti-shake module 26.

It is understood that the lower holder 262 may be movable with respect to the upper holder 261, and in order to facilitate the movement of the lower holder 262, the upper holder 261 and the lower holder 262 may be spaced apart in the optical axis direction of the lens 22, and in order to maintain the relative position of the upper holder 261 and the lower holder 262, the anti-shake module 26 further includes a connection spring (not shown) connected between the upper holder 261 and the lower holder 262, and it is understood that the connection spring has a certain flexibility so as not to hinder the movement of the lower holder 262 with respect to the upper holder 261.

It will also be appreciated that the directions of movement associated therewith with respect to the camera module 20 generally include an X-direction, a Y-direction and a Z-direction, wherein the Z-direction is the direction of the optical axis of the lens 22, and the X-direction and the Y-direction are perpendicular to each other and to the Z-direction.

Referring to fig. 8 and 9 in combination with fig. 7, fig. 8 is an exploded view of the anti-shake module shown in fig. 7, and fig. 9 is a schematic structural view of the driving member and the upper bracket in fig. 8, it can be understood that fig. 9 only illustrates a relative position relationship between the driving member and the upper bracket. The driving member 263 for driving the lower frame 262 to move may include a deformation portion 2631, the deformation portion 2631 connects the upper frame 261 and the lower frame 262, and the deformation portion 2631 may be deformed to drive the lower frame 262 to move relative to the upper frame 261 in a direction perpendicular to the optical axis of the lens 22, so as to drive the photosensitive element 25 to move in a direction perpendicular to the optical axis of the lens 22 (including an X direction and/or a Y direction), so as to achieve an optical anti-shake function of the photosensitive element 25. Illustratively, one end of the deformation part 2631 is connected to the upper bracket 261, the other end of the deformation part 2631 is connected to the lower bracket 262, and the deformation part 2631 is deformable in the power-on state to move the lower bracket 262 relative to the upper bracket 261 in a direction perpendicular to the optical axis of the lens 22. The deformation portion 2631 may be made of Shape Memory Alloy (SMA), and the Shape Memory alloy may heat and deform the SMA in a power-on state, and the length of the deformation portion 2631 may change during deformation, so as to drive the lower bracket 262 connected thereto to move, thereby implementing the anti-shake function of the photosensitive element 25. For example, the conductive pins 2621 may be disposed on the lower holder 262, and the conductive pins 2621 are electrically connected to the deformation portion 2631. Accordingly, a current can be conducted to the deformation portion 2631 through the conductive pin 2621 to deform the deformation portion 2631, so as to control the movement of the lower frame 262, and thus the movement of the photosensitive element 25.

For example, the driving parts 263 may be disposed in a plurality of, such as four, wherein two driving parts 263 are disposed oppositely in a first direction and are substantially symmetrical with respect to the lens 22, another two driving parts 263 are disposed oppositely in a second direction and are substantially symmetrical with respect to the lens 22, the first direction is perpendicular to the second direction and are both perpendicular to the optical axis direction of the lens 22, such as the first direction is the X direction, the second direction is the Y direction, and the four driving parts 263 surround and form a similar square shape. In this manner, movement of the lower bracket 262 may be accomplished by the cooperation of the four driving members 263.

Referring to fig. 2 and fig. 3, in order to control the operation of the driving member 263, the camera module 20 may further include a circuit board 27, where the circuit board 27 is disposed on a side of the photosensitive element 25 away from the lower frame 262, such as the fixing plate 251 fixed in the photosensitive element 25 by the circuit board 27. The circuit board 27 may be connected to an external device, such as a main processor of the electronic device 100. It is understood that the photosensitive chip 252 of the photosensitive element 25 is electrically connected to the circuit board 27, and the conductive pins 2621 of the lower frame 262 are electrically connected to the circuit board 27. When the lower frame 262 needs to be driven to move, the driving element 263 can be powered through the circuit board 27, the length of the deformation portion 2631 of the driving element 263 changes, so as to drive the lower frame 262 connected with the driving element to move, and when the lower frame 262 moves relative to the upper frame 261, the circuit board 27 and the photosensitive element 25 move together.

In order to enable the lower frame 262 to move more accurately, the camera module 20 may further include a hall sensor 28, the hall sensor 28 is disposed on the circuit board 27, the base 21 is provided with a supporting leg 212 disposed opposite to the hall sensor 28, the supporting leg 212 is provided with a magnet, the magnet is disposed opposite to the hall sensor 28, so that when the circuit board 27 moves along with the lower frame 262, the relative position between the hall sensor 28 and the magnet also changes, and thus the magnetic flux received by the hall sensor 28 also changes correspondingly and outputs a corresponding signal, so that the main processor of the electronic device 100 can accurately calculate the displacement of the lower frame 262 according to the signal output by the hall sensor 28, thereby accurately controlling the movement of the lower frame 262 and improving the anti-shake precision of the photosensitive element 25.

Illustratively, the base 21 is substantially a square body structure, the number of the supporting legs 212 may be four, and four supporting legs 212 are respectively and correspondingly disposed at four corners of the base 21, it can be understood that the number of the hall sensors 28 is also four, and one hall sensor 28 is disposed opposite to one supporting leg 212.

In order to more clearly describe the structure of the upper and

lower supporters

261 and 262, the detailed structure of the upper and

lower supporters

261 and 262 will be further described with reference to the accompanying drawings.

Referring to fig. 5 and fig. 6, the upper bracket 261 of the anti-shake module 26 is connected to the base 21, so as to fix the anti-shake module 26 to the base 21. It is understood that the base 21 includes a connection bottom surface 213 disposed opposite to the upper support 261, the connection bottom surface 213 is provided with a protrusion 214 protruding toward the upper support 261, and the upper support 261 is connected to the upper support 261 through the connection bottom surface 213 and the protrusion 214 to realize the fixing of the upper support 261 to the base 21.

The upper bracket 261 may include a connection body 2611, the connection body 2611 includes a first portion 26111, a connection portion 26112 and a second portion 26113, the first portion 26111 has a first connection surface disposed opposite to the bottom surface of the protrusion 214, and the first connection surface is connected to the bottom surface of the protrusion 214, for example, the first connection surface may be fixedly connected to the bottom surface of the protrusion 214 by glue.

The connecting portion 26112 is connected to an edge of the first portion 26111 and is bent toward a direction close to the base 21, the second portion 26113 is connected to the connecting portion 26112, the second portion 26113 has a second connecting surface opposite to the connecting bottom surface 213 of the base 21, and the second connecting surface is connected to the connecting bottom surface 213 of the base 21, for example, the second connecting surface and the connecting bottom surface 213 of the base 21 may be fixedly connected by glue.

In this way, the connecting body 2611 of the upper bracket 261 forms a structure that is recessed downward along the optical axis direction of the lens 22, the first portion 26111 of the connecting body 2611 is farther away from the base 21 relative to the second portion 26113 of the connecting body 2611, and the lower bracket 262 is located on the side of the upper bracket 261 facing the photosensitive element 25, that is, the lower bracket 262 is located below the first portion 26111 in the optical axis direction of the lens 22, which enables the lower bracket 262 to be farther away from the components in the mounting space 211 of the base 21, thereby further avoiding the interference between the lower bracket 262 and the base 21 or the components in the base 21 during the movement process.

It should be noted that all directional indications (such as up, down, left, right, front, and back) in the embodiments of the present application are only used for explaining the relative positional relationship between the components, the movement situation, and the like in a specific posture, and if the specific posture is changed, the directional indication is changed accordingly.

The upper bracket 261 may be made of metal, and the recess structure of the connection body 2611 may be formed by stamping.

It should be noted that, the anti-shake module 26 usually needs to be limited in the moving process, and in the related art, the wall of the base is usually used as a limiting structure to limit the anti-shake module, that is, when the anti-shake module collides with the wall of the base, the wall of the base limits the position, and when the number of times the anti-shake module collides with the wall of the base is large, the base is easily damaged.

Based on this, referring to fig. 7 and fig. 8 in combination with fig. 5, the upper bracket 261 may further include a first limiting portion 2612, the first limiting portion 2612 is connected to the connecting body 2611, a free end of the first limiting portion 2612 is bent toward a direction away from the base 21, and the first limiting portion 2612 is used for limiting the lower bracket 262. It can be understood that when the lower bracket 262 moves to abut against the first retaining portion 2612, the lower bracket 262 is retained by the first retaining portion 2612. By providing the first stopper 2612 on the upper bracket 261, the lower bracket 262 can be stopped and the lower bracket 262 can be prevented from hitting the base 21.

The first limiting portion 2612 may be made of a metal material, so that the first limiting portion 2612 can be effectively prevented from being damaged by the lower bracket 262 to generate debris, and the debris is prevented from affecting the normal operation of other components of the camera module 20, such as when the debris is scattered to the photosensitive element 25, the finally imaged image has a shadow, which affects the quality of the generated image.

It can be understood that two first limiting portions may be disposed in the first direction (or the X direction), two first limiting portions are disposed at an interval, the lower frame 262 may move between the two first limiting portions in the first direction, and when the lower frame 262 moves to abut against the first limiting portions in the first direction, the lower frame 262 may be limited by the first limiting portions in the first direction. For convenience of understanding, the two first limiting portions spaced apart from each other along the first direction are named as a first sub-limiting portion 2612a and a second sub-limiting portion 2612b, the lower bracket 262 can move between the first sub-limiting portion 2612a and the second sub-limiting portion 2612b, and the lower bracket 262 can be limited when moving to abut against the first sub-limiting portion 2612a or the second sub-limiting portion 2612 b.

Of course, two first limiting portions may also be disposed in the second direction (or the Y direction), the two first limiting portions are disposed at an interval, the lower bracket 262 may move between the two first limiting portions in the second direction, and when the lower bracket 262 moves to abut against the first limiting portions in the second direction, the lower bracket 262 may be limited by the first limiting portions in the second direction.
