Description

Technical Field

[0001] The present application relates to the field of optical imaging technology, and in particular to a camera module and electronic equipment. Background Art

[0002] At present, when an electronic device takes a photo, both autofocus and auto-anti-shake are realized by a camera module arranged in the electronic device. Specifically, the camera module can realize the autofocus function through a magnetic member for realizing the autofocus function, and realize the auto-anti-shake function through a magnetic member for realizing the auto-anti-shake function.

[0003] However, there is a serious magnetic interference problem between the magnetic field generated by the magnetic component used to achieve the focusing function and the magnetic field generated by the magnetic component used to achieve the anti-shake function, which seriously affects the performance of the camera module and further affects the performance of the entire electronic device. Summary of the invention

[0004] The present application discloses a camera module and an electronic device, which can avoid the problem of magnetic interference between the magnetic field generated by a magnetic component for realizing a focusing function and the magnetic field generated by a magnetic component for realizing an anti-shake function.

[0005] In order to achieve the above objectives, on the one hand, the present application discloses a camera module, comprising:

[0006] Base;

[0007] A liquid lens connected to the base;

[0008] A magnetic member, wherein the magnetic member is fixedly arranged relative to the base and is used to generate a magnetic field;

[0009] An anti-shake component, the anti-shake component is connected to the liquid lens, the anti-shake component comprises an anti-shake coil, and the anti-shake coil is located in the magnetic field;

[0010] A focusing assembly, the focusing assembly is connected to the liquid lens, the focusing assembly comprises a focusing coil, and the focusing coil is located in the magnetic field;

[0011] Under the action of the magnetic field, the anti-shake coil can drive the anti-shake component to move away from the initial position so as to deform the liquid lens for anti-shake. Under the action of the magnetic field, the focusing coil can drive the focusing component to move away from the initial position so as to deform the liquid lens for focusing.

[0012] Since the anti-shake coil and the focus coil are both located in the magnetic field generated by the magnetic part, and the anti-shake coil and the focus coil can be subjected to the Ampere force respectively under the action of the magnetic field, the camera module can realize the anti-shake function and the focus function. In layman's terms, the anti-shake coil and the focus coil can realize the anti-shake function and the focus function of the camera module through the magnetic field generated by the common magnetic part. In this way, there is no need to separately set up magnetic parts for realizing the anti-shake function and the magnetic parts for realizing the focus function in order to realize the anti-shake function and the focus function. Therefore, on the one hand, the problem of magnetic interference between the magnetic parts for realizing the anti-shake function and the magnetic parts for realizing the focus function can be avoided, so that the performance of the camera module is better. On the other hand, the entire camera module can also be made compact.

[0013] Optionally, the liquid lens has an optical axis, the anti-shake component is located on a side of the magnetic component away from the optical axis, and the focusing component is located on a side of the magnetic component close to the optical axis.

[0014] Because under normal circumstances, in order to realize the anti-shake function and the focus function respectively, the movement amplitude of the anti-shake component is larger than the movement amplitude of the focus component. Therefore, by locating the anti-shake component on the side of the magnetic component away from the optical axis, and locating the focus component on the side of the magnetic component close to the optical axis, that is, by locating the anti-shake component on the outside of the focus component, a larger space can be provided for the movement of the anti-shake component, and the structural design is more reasonable.

[0015] Optionally, there are multiple magnetic members, and the multiple magnetic members are arranged around the optical axis;

[0016] There are multiple anti-shake coils, and the multiple anti-shake coils are arranged in a one-to-one correspondence with the multiple magnetic members;

[0017] There are multiple focusing coils, and the multiple focusing coils are arranged in a one-to-one correspondence with the multiple magnetic members.

[0018] By increasing the number of magnetic parts and arranging the multiple magnetic parts around the optical axis, when multiple anti-shake coils are arranged one-to-one with multiple magnetic parts, and multiple focus coils are arranged one-to-one with multiple magnetic parts, on the one hand, the force conditions of the anti-shake assembly and the focus assembly can be made more uniform, and on the other hand, the magnetic field passing through the magnetic parts can provide a greater Ampere force to the anti-shake coil and the focus coil respectively.

[0019] Optionally, the anti-shake component includes a first sensing driving chip, the first sensing driving chip is electrically connected to the anti-shake coil, the first sensing driving chip is used to be electrically connected to a control module, the first sensing driving chip is used to detect changes in the magnetic field at the anti-shake coil, and the control module is used to control the magnitude, direction and on-off of the current in the anti-shake coil through the first sensing driving chip based on the changes in the magnetic field at the anti-shake coil;

[0020] The focusing component includes a second sensing driver chip, the second sensing driver chip is electrically connected to the focusing coil, the second sensing driver chip is used to be electrically connected to the control module, the second sensing driver chip is used to detect changes in the magnetic field at the focusing coil, and the control module is used to control the size, direction and on-off of the current in the focusing coil through the second sensing driver chip based on the changes in the magnetic field at the focusing coil.

[0021] On the one hand, the first sensing driver chip can detect changes in the magnetic field at the anti-shake coil. On the other hand, the control module can also control the size, direction and on-off of the current in the anti-shake coil through the first sensing driver chip. That is, the first sensing driver chip integrates multiple functions in one, and the first sensing driver chip is equivalent to the integration of multiple chips. Based on this, when the anti-shake component includes the first sensing driver chip, since the first sensing driver chip has fewer pins than multiple chips, the number of lines electrically connected to the control module can be reduced, thereby making the circuit wiring of the entire camera module more concise.

[0022] Optionally, the anti-shake component includes a first sensing chip and a first driving chip, both of which are used to be electrically connected to the control module, the first sensing chip is used to detect changes in the magnetic field at the anti-shake coil, and the control module is used to control the magnitude, direction and on-off of the current in the anti-shake coil through the first driving chip based on the changes in the magnetic field at the anti-shake coil.

[0023] The first sensing chip and the first driving chip are equivalent to the first sensing driving chip in the above-mentioned embodiment. The function of detecting the change of the magnetic field at the anti-shake coil is realized by the first sensing chip, and the function of controlling the size, direction and on-off of the current in the anti-shake coil is realized by the first driving chip. That is, the function of detecting the change of the magnetic field at the anti-shake coil and the function of controlling the size, direction and on-off of the current in the anti-shake coil are realized by different chips. In this way, each chip has its own independent function and the structure is simple.

[0024] Optionally, the focusing component includes a second sensing chip and a second driving chip, the second sensing chip is arranged on the focusing component, and the second driving chip is arranged on the base, the second sensing chip and the second driving chip are both used to be electrically connected to the control module, the second sensing chip is used to detect changes in the magnetic field at the focusing coil, and the control module is used to control the magnitude, direction and on-off of the current in the focusing coil through the second driving chip based on the changes in the magnetic field at the focusing coil.

[0025] The second sensing chip and the second driving chip are equivalent to the second sensing driving chip in the above embodiment. The function of detecting changes in the magnetic field of the focusing coil is realized by the second sensing chip, and the function of controlling the size, direction and on-off of the current in the focusing coil is realized by the second driving chip. That is, the function of detecting changes in the magnetic field at the focusing coil and the function of controlling the size, direction and on-off of the current in the focusing coil are realized by different chips. In this way, each chip has its own independent function and the structure is simple.

[0026] Optionally, the liquid lens comprises:

[0027] A supporting sheet connected to the base;

[0028] A liquid anti-shake lens and a liquid focus lens, wherein the liquid anti-shake lens and the liquid focus lens are respectively arranged on two sides of the supporting sheet;

[0029] The anti-shake component is connected to the liquid anti-shake lens, and the focusing component is connected to the liquid focusing lens. The control module is used to control the anti-shake component to move away from an initial position based on a change in the magnetic field at the anti-shake coil so that the inclination angle of the liquid anti-shake lens changes for anti-shake performance. The control module is also used to control the focusing component to move away from an initial position based on a change in the magnetic field at the focusing coil so that the curvature of the liquid focusing lens changes for focusing.

[0030] Since the anti-shake function can be achieved by changing the tilt angle of the liquid anti-shake lens of the liquid lens, and the focus function can be achieved by changing the curvature of the liquid focus lens of the liquid lens. In layman's terms, the liquid lens has two independent components, which are used to enable the camera module to achieve the anti-shake function and the focus function respectively. In this way, it is possible to avoid the situation where the anti-shake function and the focus function are realized by the same component and the interference between the functions occurs.

[0031] Optionally, the magnetic component is fixed on the base via a magnetic component bracket.

[0032] By fixing the magnetic component on the base through a magnetic component bracket, it is possible to avoid directly fixing the magnetic component on the base. In this way, the magnetic component bracket can protect the magnetic component to a certain extent, thereby extending the service life of the magnetic component.

[0033] Optionally, the camera module also includes an elastic component, which is respectively connected to the anti-shake component, the magnetic component bracket and the focusing component, and the elastic component is used to restore the anti-shake component and the focusing component to an initial position. The first sensing drive chip and the second sensing drive chip are both electrically connected to the control module through the elastic component.

[0034] Since the camera module also includes an elastic component, which is respectively connected to the anti-shake component, the magnetic bracket and the focus component, the elastic component can be used to restore the anti-shake component and the focus component to their initial positions, so that the camera module can be prepared to implement the anti-shake function and the focus function next time. In addition, since the first sensing driver chip and the second sensing driver chip are both electrically connected to the control module through the elastic component, that is, the elastic component can be used as a wire between the first sensing driver chip and the control module, and between the second sensing driver chip and the control module. The elastic component integrates multiple functions and has multiple uses. On the one hand, it can make the camera module more compact, and on the other hand, it can also make the circuit wiring of the camera module more concise.

[0035] Optionally, the elastic component includes a first elastic element and a second elastic element, the first elastic element is respectively connected to a side of the anti-shake component away from the base, a side of the magnetic component bracket away from the base, and a side of the focusing component away from the base, and the second elastic element is respectively connected to a side of the anti-shake component close to the base, a side of the magnetic component bracket close to the base, and a side of the focusing component close to the base.

[0036] When the elastic component includes a first elastic element and a second elastic element, and the first elastic element is respectively connected to a side of the anti-shake component away from the base, a side of the magnetic component bracket away from the base, and a side of the focus component away from the base, and the second elastic element is respectively connected to a side of the anti-shake component close to the base, a side of the magnetic component bracket close to the base, and a side of the focus component close to the base, the side of the focus component away from the base and the side close to the base can be respectively connected to the first elastic element and the second elastic element, so that the focus component can move more smoothly when it moves relative to the base. In addition, the side of the anti-shake component away from the base and the side close to the base can be respectively connected to the first elastic element and the second elastic element, so that the anti-shake component can move more smoothly when it moves relative to the base.

[0037] Optionally, the first elastic element includes a first fixing portion, and a first elastic arm, a second elastic arm and a third elastic arm arranged on the first fixing portion, the first fixing portion is arranged on a surface of the magnetic member bracket away from the base, an end of the first elastic arm away from the first fixing portion and an end of the third elastic arm away from the first fixing portion are both connected to the anti-shake assembly, and an end of the second elastic arm away from the first fixing portion is connected to the focusing assembly;

[0038] The second elastic element comprises a second fixing portion, a fourth elastic arm, a fifth elastic arm and a sixth elastic arm, the second fixing portion is arranged on a surface of the magnetic member bracket close to the base, an end of the fourth elastic arm away from the second fixing portion and an end of the sixth elastic arm away from the second fixing portion are both connected to the anti-shake assembly, and an end of the fifth elastic arm away from the second fixing portion is connected to the focusing assembly;

[0039] The first sensing driving chip is electrically connected to the control module through the first elastic arm, the third elastic arm, the fourth elastic arm and the sixth elastic arm, and the second sensing driving chip is electrically connected to the control module through the second elastic arm and / or the fifth elastic arm.

[0040] The first sensing drive chip is electrically connected to the control module through the first elastic arm, the third elastic arm, the fourth elastic arm and the sixth elastic arm, and the second sensing drive chip is electrically connected to the control module through the second elastic arm. That is to say, in addition to the function of restoring the anti-shake component to the initial position, the first elastic arm, the third elastic arm, the fourth elastic arm and the sixth elastic arm also serve as the wire between the first sensing drive chip and the control module. One thing has multiple uses. On the one hand, it can make the entire camera module compact, and on the other hand, it can make the circuit wiring of the camera module more concise. Similarly, in addition to the function of restoring the focus component to the initial position, the second elastic arm also serves as the wire between the second sensing drive chip and the control module. One thing has multiple uses. On the one hand, it can make the entire camera module compact, and on the other hand, it can also make the circuit wiring of the camera module more concise.

[0041] Optionally, the first elastic arm and the third elastic arm are arranged in a mirror image relative to the midline of the first fixing portion, and the fourth elastic arm and the sixth elastic arm are arranged in a mirror image relative to the midline of the second fixing portion.

[0042] When the anti-shake component moves away from the initial position, the first elastic arm and the third elastic arm can apply approximately the same elastic force to the anti-shake component, and the fourth elastic arm and the sixth elastic arm can apply approximately the same elastic force to the anti-shake component, so that the elastic force received by the anti-shake component when it moves away from the initial position can be relatively uniform, and the anti-shake component can run relatively smoothly when it moves away from the initial position.

[0043] Optionally, the length of the first elastic arm is greater than the length of the second elastic arm, and the length of the fourth elastic arm is greater than the length of the fifth elastic arm.

[0044] By making the length of the first elastic arm greater than that of the second elastic arm, and the length of the fourth elastic arm greater than that of the fifth elastic arm, the first elastic arm and the fourth elastic arm can have better deformation capabilities than the second elastic arm and the fifth elastic arm, thereby enabling the camera module to well implement anti-shake and focus functions.

[0045] Optionally, the first elastic arm, the second elastic arm, the third elastic arm, the fourth elastic arm, the fifth elastic arm and the sixth elastic arm are all formed by coiling a metal sheet.

[0046] By making the first elastic arm, the second elastic arm, the third elastic arm, the fourth elastic arm, the fifth elastic arm and the sixth elastic arm all coiled by metal sheets, on the one hand, the first elastic arm, the second elastic arm, the third elastic arm, the fourth elastic arm, the fifth elastic arm and the sixth elastic arm can all be conductive, which can simplify the circuit layout of the entire camera module. On the other hand, the first elastic arm, the second elastic arm, the third elastic arm, the fourth elastic arm, the fifth elastic arm and the sixth elastic arm can all provide elastic force, so that the anti-shake component and the focus component return to the initial position.

[0047] Optionally, a first conductive member and a second conductive member are embedded in the magnetic member bracket, the first end of the first conductive member is electrically connected to the first fixed portion, and the second end of the first conductive member is used to be electrically connected to the control module, the first end of the second conductive member is electrically connected to the second fixed portion, and the second end of the second conductive member is used to be electrically connected to the control module.

[0048] Since the first conductive member and the second conductive member are both embedded in the magnetic member bracket, on the one hand, the magnetic member bracket can protect the first conductive member and the second conductive member, thereby extending the service life of the first conductive member and the second conductive member. On the other hand, leakage of electricity at the first conductive member and the second conductive member can be avoided, thereby making the circuit of the entire camera module safer.

[0049] Optionally, the first end of the first conductive member is exposed outside the magnetic member bracket, a first through hole is provided at a position of the first fixing portion corresponding to the first end of the first conductive member, and the first end of the first conductive member is inserted into the first through hole, the first end of the second conductive member is exposed outside the magnetic member bracket, a second through hole is provided at a position of the second fixing portion corresponding to the first end of the second conductive member, and the first end of the second conductive member is inserted into the second through hole.

[0050] By setting a first through hole at a position of the first fixing portion corresponding to the first end of the first conductive member, and inserting the first end of the first conductive member into the first through hole, on the one hand, electrical connection can be achieved between the first conductive member and the first elastic element, and on the other hand, a pre-positioning relationship can be formed between the first through hole and the first end of the first conductive member, thereby simplifying the work of installing the first fixing portion on the magnetic member bracket.

[0051] By setting a second through hole at a position of the second fixing portion corresponding to the first end of the second conductive member, and inserting the first end of the second conductive member into the second through hole, on the one hand, electrical connection can be achieved between the second conductive member and the second elastic element, and on the other hand, a pre-positioning relationship can be formed between the second through hole and the first end of the second conductive member, thereby simplifying the work of installing the second fixing portion on the magnetic member bracket.

[0052] Optionally, the second end of the first conductive member is exposed outside the magnetic member bracket, and a third conductive member is embedded in the base at a position corresponding to the second end of the first conductive member, one end of the third conductive member is electrically connected to the second end of the first conductive member, and the other end is used for electrical connection to the control module;

[0053] The second end of the second conductive member is exposed outside the magnetic member bracket, and a fourth conductive member is buried at a position on the base corresponding to the second end of the second conductive member. One end of the fourth conductive member is electrically connected to the second end of the second conductive member, and the other end is used for electrical connection to the control module.

[0054] By burying the third conductive member and the fourth conductive member in the base, the base can protect the third conductive member and the fourth conductive member to a certain extent, so that, on the one hand, the service life of the third conductive member and the fourth conductive member can be extended. On the other hand, leakage of the third conductive member and the fourth conductive member can be avoided, making the circuit of the entire camera module safer.

[0055] Optionally, a support block protrudes from the base, and the second end of the first conductive member and the second end of the second conductive member are both mounted on the support block.

[0056] By placing the second end of the first conductive member and the second end of the second conductive member on the support block, the support block can support the second end of the first conductive member and the second end of the second conductive member, thereby avoiding the second end of the first conductive member and the second end of the second conductive member from collapsing or deforming. On the one hand, the service life of the first conductive member and the second conductive member can be extended. On the other hand, the possibility of contact between the second end of the first conductive member and the second end of the second conductive member due to deformation of the second end of the first conductive member and the second conductive member can be reduced or avoided, thereby reducing the possibility of short circuit between the first conductive member and the second conductive member.

[0057] Optionally, an isolation wall is disposed on the support block, and the isolation wall is located between the second end of the first conductive member and the second end of the second conductive member.

[0058] The isolation wall can separate the second end of the first conductive member and the second end of the second conductive member on different sides of the isolation wall, so that the second end of the first conductive member and the second end of the second conductive member can be prevented from contacting each other, thereby better preventing a short circuit between the first conductive member and the second conductive member.

[0059] Optionally, the second end of the first conductive member is located on a side of the third conductive member away from the isolation wall, and the second end of the second conductive member is located on a side of the fourth conductive member away from the isolation wall.

[0060] By locating the second end of the first conductive member on the side of the third conductive member away from the isolation wall, and locating the second end of the second conductive member on the side of the fourth conductive member away from the isolation wall, the third conductive member, the isolation wall and the fourth conductive member can be arranged between the second end of the first conductive member and the second end of the second conductive member, so that the second end of the first conductive member and the second end of the second conductive member can be separated as much as possible, thereby better avoiding a short circuit between the first conductive member and the second conductive member.

[0061] Optionally, the support block is a right-angled triangular protrusion, and the camera module also includes a shell, the shell cover is arranged on the base, and the two surfaces where the two right-angled sides of the protrusion are located are respectively against two adjacent inner walls of the shell.

[0062] By making the outer shell cover arranged on the base, the outer shell can protect the camera module, so that the entire camera module can be more durable. By making the support block a right-angled triangular convex block, and the two faces where the two right-angled sides of the convex block are respectively against the two adjacent inner walls of the outer shell, the convex block can play a role in pre-positioning between the outer shell and the base, so that when the outer shell is installed on the base, the installation position is more accurate.

[0063] On the other hand, the present application discloses an electronic device, which includes the camera module described in any one of the above aspects.

[0064] Since the camera module in the embodiment of the present application can avoid the problem of magnetic interference between the magnetic parts used to realize the anti-shake function and the magnetic parts used to realize the focus function, the performance of the camera module is better, and the entire camera module can be made compact. Therefore, when an electronic device includes a camera module, the performance of the electronic device can be better, and the space occupied by the camera module in the electronic device can be reduced, so that the arrangement space of other electronic components in the electronic device is more abundant.

[0065] Compared with the prior art, the beneficial effects of this application are:

[0066] Since the anti-shake coil and the focus coil are both located in the magnetic field generated by the magnetic part, and the anti-shake coil and the focus coil can be subjected to the Ampere force respectively under the action of the magnetic field, the camera module can realize the anti-shake function and the focus function. In layman's terms, the anti-shake coil and the focus coil can realize the anti-shake function and the focus function of the camera module through the magnetic field generated by the common magnetic part. In this way, there is no need to separately set up magnetic parts for realizing the anti-shake function and the magnetic parts for realizing the focus function in order to realize the anti-shake function and the focus function. Therefore, on the one hand, the problem of magnetic interference between the magnetic parts for realizing the anti-shake function and the magnetic parts for realizing the focus function can be avoided, so that the performance of the camera module is better. On the other hand, the entire camera module can also be made compact. BRIEF DESCRIPTION OF THE DRAWINGS

Under the action of the magnetic field, the anti-shake coil 41 can drive the anti-shake component 4 to move away from the initial position, so that the liquid lens 2 is deformed for anti-shake, and the focusing coil 51 can drive the focusing component 5 to move away from the initial position under the action of the magnetic field, so that the liquid lens 2 is deformed for focusing.

[0100] In the embodiment of the present application, since the magnetic member 3 is fixedly arranged relative to the base 1, the anti-shake coil 41 included in the anti-shake assembly 4 is located in the magnetic field generated by the magnetic member 3. Therefore, under the action of the magnetic field, according to the left-hand rule, the anti-shake coil 41 will be subjected to the Ampere force. After the anti-shake coil 41 is subjected to the Ampere force, the anti-shake coil 41 can move, and then the entire anti-shake assembly 4 can be driven to move away from the initial position. Since the anti-shake assembly 4 is connected to the liquid lens 2 and the liquid lens 2 is connected to the base 1, when the anti-shake assembly 4 moves away from the initial position, the liquid lens 2 can be deformed. After the liquid lens 2 is deformed, the camera module can achieve the anti-shake function.

[0101] Since the focusing coil 51 included in the focusing assembly 5 is also located in the magnetic field generated by the magnetic part 3, under the action of the magnetic field, according to the left-hand rule, the focusing coil 51 will be subjected to the Ampere force. After the focusing coil 51 is subjected to the Ampere force, the focusing coil 51 can move, and then the entire focusing assembly 5 can be driven to move away from the initial position. Since the focusing assembly 5 is connected to the liquid lens 2 and the liquid lens 2 is connected to the base 1, when the focusing assembly 5 moves away from the initial position, the liquid lens 2 can be deformed. After the liquid lens 2 is deformed, the camera module can realize the focusing function.

[0102] Among them, since the anti-shake coil 41 and the focus coil 51 are both located in the magnetic field generated by the magnetic part 3, and the anti-shake coil 41 and the focus coil 51 can be subjected to the Ampere force respectively under the action of the magnetic field, the camera module can realize the anti-shake function and the focus function. In layman's terms, the anti-shake coil 41 and the focus coil 51 can realize the anti-shake function and the focus function of the camera module through the magnetic field generated by the common magnetic part 3. In this way, there is no need to separately set up the magnetic part 3 for realizing the anti-shake function and the magnetic part 3 for realizing the focus function in order to realize the anti-shake function and the focus function. Therefore, on the one hand, the problem of magnetic interference between the magnetic part 3 for realizing the anti-shake function and the magnetic part 3 for realizing the focus function can be avoided, so that the performance of the camera module is better, and on the other hand, the entire camera module can also be made compact.

[0103] In addition, since the camera module can realize the anti-shake function and the focusing function by deforming the liquid lens 2, that is, the liquid lens 2 integrates multiple functions, the volume of the camera module can be further reduced.

[0104] It should be noted that the magnetic component 3 can be any component that can generate a magnetic field, such as a magnet or a magnet, and the embodiment of the present application does not limit the magnetic component 3. The anti-shake component 4 and the focus component 5 can be connected to the liquid lens 2 by gluing, or by other methods, and the embodiment of the present application does not limit this.

[0105] In addition, the liquid lens 2 can be connected to the base 1 in a variety of ways, as long as the liquid lens 2 and the base 1 can be connected, and the present application embodiment does not limit this. In one possible implementation, for example, see Figure 1 The liquid lens 2 can be connected to the base 1 through the lens bracket 9.

[0106] In some embodiments, see Figure 3The liquid lens 2 has an optical axis Z, the anti-shake component 4 is located on the side of the magnetic component 3 away from the optical axis Z, and the focusing component 5 is located on the side of the magnetic component 3 close to the optical axis Z. In general, in order to realize the anti-shake function and the focusing function respectively, the movement amplitude of the anti-shake component 4 is larger than the movement amplitude of the focusing component 5. Therefore, by making the anti-shake component 4 located on the side of the magnetic component 3 away from the optical axis Z, and the focusing component 5 located on the side of the magnetic component 3 close to the optical axis Z, that is, by making the anti-shake component 4 located outside the focusing component 5, a larger space can be provided for the movement of the anti-shake component 4, and the structural design is more reasonable.

[0107] Of course, in other embodiments, the anti-shake component 4 may also be located on the side of the magnetic component 3 close to the optical axis Z, and the focusing component 5 may also be located on the side of the magnetic component 3 away from the optical axis Z. It only needs to be able to cause the liquid lens 2 to deform and enable the camera module to achieve the anti-shake function and the focusing function. The embodiments of the present application are not limited to this.

[0108] In order to make the force of the anti-shake component 4 and the focus component 5 more uniform, and to make the magnetic field passing through the magnetic component 3 provide a larger Ampere force to the anti-shake coil 41 and the focus coil 51 respectively, further, in some embodiments, see Figure 3 , the number of magnetic members 3 is multiple ( Figure 3 The number of magnetic parts is 4), and multiple magnetic parts 3 are arranged around the optical axis Z. The number of anti-shake coils 41 is multiple, and the multiple anti-shake coils 41 are arranged in a one-to-one correspondence with the multiple magnetic parts 3. The number of focusing coils 51 is multiple, and the multiple focusing coils 51 are arranged in a one-to-one correspondence with the multiple magnetic parts 3. By making the number of magnetic parts 3 multiple, and making the multiple magnetic parts 3 arranged around the optical axis Z, in this way, when the multiple anti-shake coils 41 are arranged in a one-to-one correspondence with the multiple magnetic parts 3, and the multiple focusing coils 51 are arranged in a one-to-one correspondence with the multiple magnetic parts 3, on the one hand, the force conditions of the anti-shake component 4 and the focusing component 5 can be made more uniform, and on the other hand, the magnetic field through the magnetic part 3 can also provide a greater Ampere force to the anti-shake coil 41 and the focusing coil 51 respectively.

[0109] It should be noted that the number of magnetic parts 3 can be any possible number such as 4, 5 or 6, and the embodiment of the present application does not limit this. Similarly, the number of anti-shake coils 41 and focus coils 51 can also be any possible number such as 4, 5 or 6, and the embodiment of the present application does not limit this.

[0110] In some embodiments, see Figure 4 The anti-shake component 4 includes a first sensing driving chip 42, which is electrically connected to the anti-shake coil 41. The first sensing driving chip 42 is used to communicate with the control module ( Figure 4The first sensing driver chip 42 is electrically connected to the anti-shake coil 41 (not shown), and is used to detect changes in the magnetic field at the anti-shake coil 41. The control module is used to control the size, direction and on-off of the current in the anti-shake coil 41 through the first sensing driver chip 42 based on the changes in the magnetic field at the anti-shake coil 41.

[0111] In this embodiment, when anti-shake is performed, first, the change of the magnetic field at the anti-shake coil 41 can be detected by the first sensing driver chip 42. After the first sensing driver chip 42 detects the change of the magnetic field at the anti-shake coil 41, since the first sensing driver chip 42 is electrically connected to the control module, the control module can obtain the change of the magnetic field at the anti-shake coil 41. After the control module obtains the change of the magnetic field at the anti-shake coil 41, the control module can obtain the position of the anti-shake coil 41 relative to the magnetic part 3 according to the change of the magnetic field at the anti-shake coil 41 (the greater the intensity of the magnetic field at the anti-shake coil 41, the closer the distance between the anti-shake coil 41 and the magnetic part 3, and the smaller the intensity of the magnetic field at the anti-shake coil 41, the farther the distance between the anti-shake coil 41 and the magnetic part 3).

[0112] After the control module obtains the position of the anti-shake coil 41 relative to the magnetic part 3, since the first sensing drive chip 42 is also electrically connected to the anti-shake coil 41, the control module can control the size, direction and on-off of the current in the anti-shake coil 41 through the first sensing drive chip 42 according to the target position of the anti-shake coil 41 required to achieve anti-shake, and then change the position of the anti-shake coil 41 relative to the magnetic part 3 until the anti-shake coil 41 reaches the target position. After the anti-shake coil 41 reaches the target position, the anti-shake function can be achieved.

[0113] Among them, it can be known from the above description that, on the one hand, the first sensing driver chip 42 can detect the change of the magnetic field at the anti-shake coil 41, and on the other hand, the control module can also control the magnitude, direction and on-off of the current in the anti-shake coil 41 through the first sensing driver chip 42. That is, in addition to the function of detecting the change of the magnetic field at the anti-shake coil, the first sensing driver chip 42 can also realize the function of controlling the magnitude, direction and on-off of the current in the anti-shake coil. In other words, the first sensing driver chip 42 integrates multiple functions in one, and the first sensing driver chip 42 is equivalent to the integration of multiple chips. Based on this, when the anti-shake component 4 includes the first sensing driver chip 42, since the first sensing driver chip 42 has a smaller number of pins than multiple chips, the number of lines electrically connected to the control module can be reduced, and the circuit wiring of the entire camera module can be made more concise.

[0114] For example, in some embodiments, see Figure 5, the first sensing driver chip 42 may include a VSS pin 421, a VDD pin 422, an SDA pin 423, an SC1 pin 424, an OUT1 pin 425, and an OUT2 pin 426, wherein the OUT1 pin 425 and the OUT2 pin 426 may be electrically connected to the anti-shake coil 41, and all or part of the VSS pin 421, the VDD pin 422, the SDA pin 423, and the SC1 pin 424 may be used to be electrically connected to the control module. When the first sensing driver chip 42 integrates multiple functions, it is obvious that the number of pins in the entire anti-shake component 4 can be greatly reduced, thereby making the circuit wiring of the entire camera module more concise.

[0115] For example, assuming that the first sensing driver chip 42 is equivalent to the A chip and the B chip, the first sensing driver chip 42, the A chip and the B chip all have 6 pins, when the anti-shake component 4 includes the first sensing driver chip 42, the anti-shake component 4 has only 6 pins, and when the anti-shake component 4 includes the A chip and the B chip, the anti-shake component 4 will have 12 pins. Obviously, when the anti-shake component 4 includes the first sensing driver chip 42, the number of lines electrically connected to the control module can be reduced, thereby making the circuit wiring of the entire camera module more concise.

[0116] It should be noted that the above-mentioned control module refers to an electronic component that can be used to control the camera module for anti-shake and focus. In a possible embodiment, the control module may refer to a CPU (Central Processing Unit), etc. The embodiment of the present application does not limit the control module.

[0117] In addition, the purpose of changing the size, direction and on-off of the current in the anti-shake coil 41 is to change the size and direction of the Ampere force applied to the anti-shake coil 41. When the size and direction of the Ampere force applied to the anti-shake coil 41 change, the position of the anti-shake coil 41 relative to the magnetic part 3 can be changed, and then the liquid lens 2 can be deformed, thereby realizing the anti-shake function.

[0118] Specifically, according to F=ILB, where F refers to the Ampere force, I refers to the current, L refers to the length of the conductor in the magnetic field, and B refers to the strength of the magnetic field, it can be seen that the Ampere force is directly proportional to the current. Therefore, by changing the magnitude, direction, and on-off of the current in the anti-shake coil 41, the magnitude and direction of the Ampere force on the anti-shake coil 41 can be changed.

[0119] In other embodiments, the anti-shake component includes a first sensing chip and a first driving chip, both of which are used to be electrically connected to the control module. The first sensing chip is used to detect changes in the magnetic field at the anti-shake coil, and the control module is used to control the size, direction and on-off of the current in the anti-shake coil through the first driving chip based on the changes in the magnetic field at the anti-shake coil.

[0120] In this embodiment, the first sensing chip and the first driving chip are equivalent to the first sensing driving chip 42 in the above embodiment. The function of detecting the change of the magnetic field at the anti-shake coil is realized by the first sensing chip, and the function of controlling the size, direction and on-off of the current in the anti-shake coil is realized by the first driving chip. That is, the function of detecting the change of the magnetic field at the anti-shake coil and the function of controlling the size, direction and on-off of the current in the anti-shake coil are realized by different chips. In this way, each chip has its own independent function and the structure is simple.

[0121] Among them, the first sensing chip can be a Hall element or any component that can detect the change of the magnetic field at the anti-shake coil, and the embodiment of the present application is not limited to this.

[0122] In some embodiments, see Figure 6 The focusing assembly 5 includes a second sensing driving chip 52, which is electrically connected to the focusing coil 51. The second sensing driving chip 52 is used to be electrically connected to the control module. The second sensing driving chip 52 is used to detect changes in the magnetic field at the focusing coil 51. The control module is used to control the size, direction and on-off of the current in the focusing coil 51 through the second sensing driving chip 52 based on the changes in the magnetic field at the focusing coil 51.

[0123] In this embodiment, when focusing is performed, first, the change of the magnetic field at the focus coil 51 can be detected by the second sensing driver chip 52. After the second sensing driver chip 52 detects the change of the magnetic field at the focus coil 51, since the second sensing driver chip 52 is electrically connected to the control module, the control module can obtain the change of the magnetic field at the focus coil 51. After the control module obtains the change of the magnetic field at the focus coil 51, the control module can obtain the position of the focus coil 51 relative to the magnetic part 3 according to the change of the magnetic field at the focus coil 51.

[0124] After the control module obtains the position of the focus coil 51 relative to the magnetic part 3, since the second sensing drive chip 52 is also electrically connected to the focus coil 51, the control module can control the size, direction and on-off of the current in the focus coil 51 through the second sensing drive chip 52 according to the target position of the focus coil 51 required to complete the focusing, thereby changing the position of the focus coil 51 relative to the magnetic part 3 until the focus coil 51 reaches the target position. After the focus coil 51 reaches the target position, the focusing function can be realized.

[0125] It can be seen from the above description that, on the one hand, the second sensing driver chip 52 can detect the change of the magnetic field at the focus coil 51, and on the other hand, the control module can also control the magnitude, direction and on-off of the current in the focus coil 51 through the second sensing driver chip 52. That is, the second sensing driver chip 52 integrates multiple functions. Based on this, when the focus assembly 5 includes the second sensing driver chip 52, the number of lines electrically connected to the control module can be reduced, thereby making the circuit wiring of the entire camera module more concise.

[0126] In other embodiments, the focusing component 5 may include a second sensing chip and a second driving chip, both of which are used to be electrically connected to the control module, the second sensing chip is used to detect changes in the magnetic field at the focusing coil 51, and the control module is used to control the size, direction and on-off of the current in the focusing coil 51 through the second driving chip based on the changes in the magnetic field at the focusing coil 51.

[0127] In this embodiment, the second sensing chip and the second driving chip are equivalent to the second sensing driving chip 52 in the above embodiment. The function of detecting the change of the magnetic field of the focusing coil 51 is realized by the second sensing chip, and the function of controlling the size, direction and on-off of the current in the focusing coil 51 is realized by the second driving chip. That is, the function of detecting the change of the magnetic field at the focusing coil 51 and the function of controlling the size, direction and on-off of the current in the focusing coil 51 are realized by different chips. In this way, each chip has its own independent function and the structure is simple.

[0128] In some embodiments, see Figure 2 and Figure 3The liquid lens 2 includes: a supporting sheet 21, a liquid anti-shake lens 22 and a liquid focus lens 23. The supporting sheet 21 is connected to the base 1. The liquid anti-shake lens 22 and the liquid focus lens 23 are respectively arranged on both sides of the supporting sheet 21. The anti-shake component 4 is connected to the liquid anti-shake lens 22, and the focusing component 5 is connected to the liquid focus lens 23. The control module is used to control the anti-shake component 4 to move away from the initial position based on the change of the magnetic field at the anti-shake coil 41, so that the inclination angle of the liquid anti-shake lens 22 changes, and anti-shake is performed. The control module is also used to control the focus component 5 to move away from the initial position based on the change of the magnetic field at the focus coil 51, so that the curvature of the liquid focus lens 23 changes, and focusing is performed.

[0129] In this embodiment, when anti-shake is performed, first, the control module can control the anti-shake component 4 to move away from the initial position based on the change of the magnetic field at the anti-shake coil 41 of the anti-shake component 4. Since the anti-shake component 4 is connected to the liquid anti-shake lens 22, and since the supporting plate 21 is connected to the base 1, the liquid anti-shake lens 22 is arranged on one side of the supporting plate 21. Therefore, when the anti-shake component 4 moves away from the initial position, the inclination angle of the liquid anti-shake lens 22 can be changed, so that the anti-shake function can be achieved.

[0130] When focusing, first, the control module can control the focus component 5 to move away from the initial position based on the change of the magnetic field at the focus coil 51 of the focus component 5. Since the focus component 5 is connected to the liquid focus lens 23, and since the supporting plate 21 is connected to the base 1, the liquid focus lens 23 is arranged on the other side of the supporting plate 21. Therefore, when the focus component 5 moves away from the initial position, the curvature of the liquid focus lens 23 can be changed, so that the focusing function can be achieved.

[0131] Among them, the anti-shake function can be realized by changing the tilt angle of the liquid anti-shake lens 22 of the liquid lens 2, and the focusing function can be realized by changing the curvature of the liquid focusing lens 23 of the liquid lens 2. In layman's terms, the liquid lens 2 has two independent components, which are used to respectively enable the camera module to realize the anti-shake function and the focusing function. In this way, it is possible to avoid the situation where the anti-shake function and the focusing function are realized by the same component and the interference between the functions occurs.

[0132] It should be noted that the liquid anti-shake lens 22 and the liquid focus lens 23 can be respectively set on both sides of the supporting sheet 21 by gluing, or can be set on both sides of the supporting sheet 21 by other methods, and the embodiment of the present application is not limited to this.

[0133] In some embodiments, see Figure 3, the magnetic member 3 is fixedly arranged on the base 1 through the magnetic member bracket 6. By making the magnetic member 3 fixedly arranged on the base 1 through the magnetic member bracket 6, it is possible to avoid the situation where the magnetic member 3 is directly fixedly arranged on the base 1. In this way, the magnetic member bracket 6 can protect the magnetic member 3 to a certain extent, thereby extending the service life of the magnetic member 3.

[0134] The material of the magnetic bracket 6 may be plastic, rubber, etc., and the embodiment of the present application does not limit the material of the magnetic bracket 6.

[0135] In some embodiments, see Figure 7 The camera module also includes an elastic component 7, which is respectively connected to the anti-shake component 4, the magnetic bracket 6 and the focus component 5. The elastic component 7 is used to restore the anti-shake component 4 and the focus component 5 to their initial positions. The first sensing driver chip 42 and the second sensing driver chip 52 are both electrically connected to the control module through the elastic component 7.

[0136] After the camera module completes the anti-shake function and the focus function, since the camera module also includes an elastic component 7, and the elastic component 7 is respectively connected to the anti-shake component 4, the magnetic bracket 6 and the focus component 5, the elastic component 7 can restore the anti-shake component 4 and the focus component 5 to their initial positions, so that the camera module can be prepared to realize the anti-shake function and the focus function next time. In addition, since the first sensing driver chip 42 and the second sensing driver chip 52 are both electrically connected to the control module through the elastic component 7, that is, the elastic component 7 can be used as a wire between the first sensing driver chip 42 and the control module, and between the second sensing driver chip 52 and the control module. The elastic component 7 integrates multiple functions and has multiple uses. On the one hand, it can make the camera module more compact, and on the other hand, it can also make the circuit wiring of the camera module more concise.

[0137] In some embodiments, see Figure 7 The elastic component 7 includes a first elastic element 71 and a second elastic element 72. The first elastic element 71 is respectively connected to a side of the anti-shake component 4 away from the base 1, a side of the magnetic bracket 6 away from the base 1, and a side of the focusing component 5 away from the base 1. The second elastic element 72 is respectively connected to a side of the anti-shake component 4 close to the base 1, a side of the magnetic bracket 6 close to the base 1, and a side of the focusing component 5 close to the base 1.

[0138] When the elastic component 7 includes a first elastic element 71 and a second elastic element 72, and the first elastic element 71 is respectively connected to a side of the anti-shake component 4 away from the base 1, a side of the magnetic bracket 6 away from the base 1, and a side of the focus component 5 away from the base 1, and the second elastic element 72 is respectively connected to a side of the anti-shake component 4 close to the base 1, a side of the magnetic bracket 6 close to the base 1, and a side of the focus component 5 close to the base 1, the side of the focus component 5 away from the base 1 and the side close to the base 1 can be respectively connected to the first elastic element 71 and the second elastic element 72, so that the focus component 5 can move more smoothly when it moves relative to the base 1. In addition, the side of the anti-shake component 4 away from the base 1 and the side close to the base 1 can be respectively connected to the first elastic element 71 and the second elastic element 72, so that the anti-shake component 4 can move more smoothly when it moves relative to the base 1.

[0139] The first elastic element 71 and the second elastic element 72 may both be metal springs, or any other possible elastic elements. The embodiment of the present application does not limit the first elastic element 71 and the second elastic element 72 .

[0140] In some embodiments, see Figure 7 The first elastic element 71 includes a first fixed portion 711, and a first elastic arm 712, a second elastic arm 713 and a third elastic arm 714 arranged on the first fixed portion 711. The first fixed portion 711 is arranged on a surface of the magnetic bracket 6 away from the base 1. One end of the first elastic arm 712 away from the first fixed portion 711 and one end of the third elastic arm 714 away from the first fixed portion 711 are both connected to the anti-shake component 4, and one end of the second elastic arm 713 away from the first fixed portion 711 is connected to the focusing component 5.

[0141] See also Figure 8 The second elastic element 72 includes a second fixing portion 721, a fourth elastic arm 722, a fifth elastic arm 723 and a sixth elastic arm 724. The second fixing portion 721 is disposed on a surface of the magnetic member bracket 6 close to the base 1. The end of the fourth elastic arm 722 away from the second fixing portion 721 and the end of the sixth elastic arm 724 away from the second fixing portion 721 are both connected to the anti-shake assembly 4. The end of the fifth elastic arm 723 away from the second fixing portion 721 is connected to the focus assembly 5. The first sensing driver chip 42 is electrically connected to the control module through the first elastic arm 712, the third elastic arm 714, the fourth elastic arm 722 and the sixth elastic arm 724. The second sensing driver chip 52 is electrically connected to the control module through the second elastic arm 713.

[0142] In this embodiment, since the first fixing portion 711 is arranged on the side of the magnetic member bracket 6 away from the base 1, the first elastic arm 712 and the third elastic arm 714 are both fixed on the first fixing portion 711 and the end of the first elastic arm 712 away from the first fixing portion 711 and the end of the third elastic arm 714 away from the first fixing portion 711 are both connected to the anti-shake component 4, and since the second fixing portion 721 is arranged on the side of the magnetic member bracket 6 close to the base 1, the end of the fourth elastic arm 722 away from the second fixing portion 721 and the end of the sixth elastic arm 724 away from the second fixing portion 721 are both connected to the anti-shake component 4. Therefore, when anti-shake is performed, as the anti-shake component 4 leaves the initial position and starts to move, the first elastic arm 712, the third elastic arm 714, the fourth elastic arm 722 and the sixth elastic arm 724 can all be deformed following the movement of the anti-shake component 4, and can restore the anti-shake component 4 to its initial position after the anti-shake function is completed, so that preparations can be made for the camera module to implement the anti-shake function next time.

[0143] Since the second elastic arm 713 is fixed on the first fixed part 711, and the end of the second elastic arm 713 away from the first fixed part 711 is connected to the focus assembly 5, and since the fifth elastic arm 723 is fixed on the second fixed part 721, and the end of the fifth elastic arm 723 away from the second fixed part 721 is connected to the focus assembly 5, therefore, when focusing, as the focus assembly 5 leaves the initial position and starts to move, the second elastic arm 713 and the fifth elastic arm 723 can both be deformed following the movement of the focus assembly 5, and can restore the focus assembly 5 to its initial position after the focus function is completed, so that preparations can be made for the camera module to implement the focus function next time.

[0144] In addition, the first sensing driver chip 42 is electrically connected to the control module through the first elastic arm 712, the third elastic arm 714, the fourth elastic arm 722 and the sixth elastic arm 724, and the second sensing driver chip 52 is electrically connected to the control module through the second elastic arm 713. That is to say, the first elastic arm 712, the third elastic arm 714, the fourth elastic arm 722 and the sixth elastic arm 724 can not only restore the anti-shake component 4 to the initial position, but also serve as the wire between the first sensing driver chip 42 and the control module. One object has multiple uses. On the one hand, it can make the entire camera module compact, and on the other hand, it can make the circuit wiring of the camera module more concise. Similarly, the second elastic arm 713 can not only restore the focus component 5 to the initial position, but also serve as the wire between the second sensing driver chip 52 and the control module. One object has multiple uses. On the one hand, it can make the entire camera module compact, and on the other hand, it can also make the circuit wiring of the camera module more concise.

[0145] Of course, in other embodiments, the second sensing driver chip 52 can also be electrically connected to the control module through the fifth elastic arm 723, or the second sensing driver chip 52 is electrically connected to the control module through the second elastic arm 713 and the fifth elastic arm 723 at the same time. The circuit can be flexibly arranged as needed, and the embodiments of the present application are not limited to this.

[0146] In order to make the anti-shake assembly 4 move more smoothly when it leaves the initial position, in some embodiments, see Figure 7 and Figure 8 , the first elastic arm 712 and the third elastic arm 714 are mirror images relative to the midline M1 of the first fixing portion 711, and the fourth elastic arm 722 and the sixth elastic arm 724 are mirror images relative to the midline M2 of the second fixing portion 721. In this way, when the anti-shake component 4 moves away from the initial position, the first elastic arm 712 and the third elastic arm 714 can apply substantially the same elastic force to the anti-shake component 4, and the fourth elastic arm 722 and the sixth elastic arm 724 can apply substantially the same elastic force to the anti-shake component 4, so that when the anti-shake component 4 moves away from the initial position, the elastic force received is relatively uniform, and thus when the anti-shake component 4 moves away from the initial position, the operation is relatively stable.

[0147] Based on the above description, it can be known that the first elastic arm 712 and the fourth elastic arm 722 are mainly used for the camera module to deform with the movement of the anti-shake component 4 when the camera module is anti-shake, and the second elastic arm 713 and the fifth elastic arm 723 are mainly used for the camera module to deform with the movement of the focus component 5 when the camera module is focusing. It can be understood that the movement amplitude of the anti-shake component 4 is larger than that of the focus component 5. Therefore, see Figure 7 and Figure 8 By making the length of the first elastic arm 712 greater than the length of the second elastic arm 713, and the length of the fourth elastic arm 722 greater than the length of the fifth elastic arm 723, the first elastic arm 712 and the fourth elastic arm 722 can have better deformation capabilities than the second elastic arm 713 and the fifth elastic arm 723, so that the camera module can well realize the anti-shake function and the focusing function.

[0148] The length of the first elastic arm 712 being greater than the length of the second elastic arm 713 means that the maximum deformable amount of the first elastic arm 712 is greater than the maximum deformable amount of the second elastic arm 713. The maximum deformable amount refers to the difference between the length of the elastic arm after deformation and the length before deformation.

[0149] In addition, the fact that the length of the fourth elastic arm 722 is greater than the length of the fifth elastic arm 723 has the same meaning as the fact that the length of the first elastic arm 712 is greater than the length of the second elastic arm 713 , which will not be described in detail herein.

[0150] In some embodiments, the first elastic arm 712, the second elastic arm 713, the third elastic arm 714, the fourth elastic arm 722, the fifth elastic arm 723 and the sixth elastic arm 724 are all formed by coiling a metal sheet. By making the first elastic arm 712, the second elastic arm 713, the third elastic arm 714, the fourth elastic arm 722, the fifth elastic arm 723 and the sixth elastic arm 724 all coiled by a metal sheet, on the one hand, the first elastic arm 712, the second elastic arm 713, the third elastic arm 714, the fourth elastic arm 722, the fifth elastic arm 723 and the sixth elastic arm 724 can all be conductive, which can simplify the circuit layout of the entire camera module. On the other hand, the first elastic arm 712, the second elastic arm 713, the third elastic arm 714, the fourth elastic arm 722, the fifth elastic arm 723 and the sixth elastic arm 724 can all provide elastic force to restore the anti-shake component 4 and the focus component 5 to their initial positions.

[0151] Of course, the first elastic arm 712 , the second elastic arm 713 , the third elastic arm 714 , the fourth elastic arm 722 , the fifth elastic arm 723 and the sixth elastic arm 724 may also be manufactured by other methods, which is not limited in the embodiment of the present application.

[0152] In some embodiments, see Figure 7 and Fig. 9 A first conductive member 61 and a second conductive member 62 are embedded in the magnetic member bracket 6. The first end of the first conductive member 61 is electrically connected to the first fixed portion 711, and the second end of the first conductive member 61 is used to be electrically connected to the control module. The first end of the second conductive member 62 is electrically connected to the second fixed portion 721, and the second end of the second conductive member 62 is used to be electrically connected to the control module.

[0153] By burying the first conductive member 61 in the magnetic member bracket 6, and making the first end of the first conductive member 61 electrically connected to the first fixed portion 711, and the second end of the first conductive member 61 electrically connected to the control module, the entire first elastic element 71 can be electrically connected to the control module, and then the purpose of electrically connecting the first sensing drive chip 42 and the second sensing drive chip 52 to the control module through the first elastic element 71 can be achieved. Similarly, by burying the second conductive member 62 in the magnetic member bracket 6, and making the first end of the second conductive member 62 electrically connected to the second fixed portion 721, and the second end of the second conductive member 62 electrically connected to the control module, the entire second elastic element 72 can be electrically connected to the control module, and then the purpose of electrically connecting the first sensing drive chip 42 and the second sensing drive chip 52 to the control module through the second elastic element 72 can be achieved.

[0154] Among them, since the first conductive member 61 and the second conductive member 62 are both embedded in the magnetic member bracket 6, on the one hand, the magnetic member bracket 6 can protect the first conductive member 61 and the second conductive member 62, so that the service life of the first conductive member 61 and the second conductive member 62 is longer. On the other hand, it can also avoid leakage at the first conductive member 61 and the second conductive member 62, making the circuit of the entire camera module safer.

[0155] Further, in some embodiments, see Figure 7 and Figure 8 The first end of the first conductive component 61 is exposed outside the magnetic component bracket 6, the first fixing portion 711 is provided with a first through hole 7111 at a position corresponding to the first end of the first conductive component 61, and the first end of the first conductive component 61 is inserted into the first through hole 7111, the first end of the second conductive component 62 is exposed outside the magnetic component bracket 6, the second fixing portion 721 is provided with a second through hole 7211 at a position corresponding to the first end of the second conductive component 62, and the first end of the second conductive component 62 is inserted into the second through hole 7211.

[0156] By setting a first through hole 7111 at a position of the first fixing portion 711 corresponding to the first end of the first conductive component 61, and inserting the first end of the first conductive component 61 into the first through hole 7111, on the one hand, electrical connection can be achieved between the first conductive component 61 and the first elastic element 71, and on the other hand, a pre-positioning relationship can be formed between the first through hole 7111 and the first end of the first conductive component 61, thereby simplifying the work of installing the first fixing portion 711 on the magnetic component bracket 6.

[0157] Similarly, by setting a second through hole 7211 at a position of the second fixing portion 721 corresponding to the first end of the second conductive member 62, and inserting the first end of the second conductive member 62 into the second through hole 7211, on the one hand, an electrical connection can be achieved between the second conductive member 62 and the second elastic element 72, and on the other hand, a pre-positioning relationship can be formed between the second through hole 7211 and the first end of the second conductive member 62, thereby simplifying the work of installing the second fixing portion 721 on the magnetic member bracket 6.

[0158] It should be noted that the shapes of the first through hole 7111 and the second through hole 7211 can be circular or rectangular, etc., and this embodiment of the present application is not limited to this.

[0159] In some embodiments, see Figure 7, the second end of the first conductive member 61 is exposed outside the magnetic member bracket 6, and a third conductive member 11 is buried at a position corresponding to the second end of the first conductive member 61 on the base 1, one end of the third conductive member 11 is electrically connected to the second end of the first conductive member 61, and the other end is used for electrical connection with the control module. The second end of the second conductive member 62 is exposed outside the magnetic member bracket 6, and a fourth conductive member 12 is buried at a position corresponding to the second end of the second conductive member 62 on the base 1, one end of the fourth conductive member 12 is electrically connected to the second end of the second conductive member 62, and the other end is used for electrical connection with the control module.

[0160] By making the second end of the first conductive member 61 exposed outside the magnetic member bracket 6, and burying the third conductive member 11 at a position on the base 1 corresponding to the second end of the first conductive member 61, the first conductive member 61 can be electrically connected to the third conductive member 11. Since the third conductive member 11 is electrically connected to the control module, after the first conductive member 61 and the third conductive member 11 are electrically connected, the first conductive member 61 can be electrically connected to the control module, and then the first elastic element 71 can be electrically connected to the control module.

[0161] By making the second end of the second conductive member 62 exposed outside the magnetic member bracket 6, and burying the fourth conductive member 12 at a position on the base 1 corresponding to the second end of the second conductive member 62, the second conductive member 62 can be electrically connected to the fourth conductive member 12. Since the fourth conductive member 12 is electrically connected to the control module, after the second conductive member 62 is electrically connected to the fourth conductive member 12, the second conductive member 62 can be electrically connected to the control module, and then the second elastic element 72 can be electrically connected to the control module.

[0162] By burying the third conductive member 11 and the fourth conductive member 12 in the base 1, the base 1 can protect the third conductive member 11 and the fourth conductive member 12 to a certain extent, so that, on the one hand, the service life of the third conductive member 11 and the fourth conductive member 12 can be extended. On the other hand, leakage of the third conductive member 11 and the fourth conductive member 12 can be avoided, making the circuit of the entire camera module safer.

[0163] In some embodiments, see Figure 7 A support block 13 protrudes from the base 1 , and the second end of the first conductive member 61 and the second end of the second conductive member 62 are both mounted on the support block 13 .

[0164] By placing the second end of the first conductive member 61 and the second end of the second conductive member 62 on the support block 13, the support block 13 can support the second end of the first conductive member 61 and the second end of the second conductive member 62, thereby preventing the second end of the first conductive member 61 and the second end of the second conductive member 62 from collapsing or deforming. On the one hand, the service life of the first conductive member 61 and the second conductive member 62 can be extended. On the other hand, the possibility of contact between the second end of the first conductive member 61 and the second end of the second conductive member 62 due to deformation thereof can be reduced or avoided, thereby reducing the possibility of short circuit between the first conductive member 61 and the second conductive member 62.

[0165] In order to better avoid the short circuit between the first conductive member 61 and the second conductive member 62, further, in some embodiments, see Figure 7 , an isolation wall 131 is provided on the support block 13, and the isolation wall 131 is located between the second end of the first conductive member 61 and the second end of the second conductive member 62. In this way, the isolation wall 131 can separate the second end of the first conductive member 61 and the second end of the second conductive member 62 on different sides of the isolation wall 131. In this way, the second end of the first conductive member 61 and the second end of the second conductive member 62 can be prevented from contacting each other, thereby better preventing the first conductive member 61 and the second conductive member 62 from short-circuiting.

[0166] In order to better avoid the short circuit between the first conductive member 61 and the second conductive member 62, further, in some embodiments, see Figure 7 , the second end of the first conductive member 61 is located on the side of the third conductive member 11 away from the isolation wall 131, and the second end of the second conductive member 62 is located on the side of the fourth conductive member 12 away from the isolation wall 131. By making the second end of the first conductive member 61 located on the side of the third conductive member 11 away from the isolation wall 131, and the second end of the second conductive member 62 located on the side of the fourth conductive member 12 away from the isolation wall 131, the third conductive member 11, the isolation wall 131 and the fourth conductive member 12 can be arranged between the second end of the first conductive member 61 and the second end of the second conductive member 62, so that the second end of the first conductive member 61 and the second end of the second conductive member 62 can be separated as much as possible, so that the short circuit between the first conductive member 61 and the second conductive member 62 can be better avoided.

[0167] In some embodiments, see Fig.10 and Fig.11The support block 13 is a right-angled triangular convex block. The camera module also includes a shell 8, which is covered on the base 1, and the two faces where the two right-angled sides of the convex block are located are respectively against the two adjacent inner walls of the shell 8.

[0168] When the camera module also includes a housing 8, the housing 8 can protect the camera module by covering the base 1, thereby making the entire camera module more durable. By making the support block 13 a right-angled triangular convex block, and the two faces where the two right-angled sides of the convex block are located respectively abutting against the two adjacent inner walls of the housing 8, the convex block can play a role in pre-positioning the housing 8 and the base 1, so that when the housing 8 is installed on the base 1, the installation position is more accurate.

[0169] In summary, in the embodiment of the present application, since the anti-shake coil 41 and the focus coil 51 are both located in the magnetic field generated by the magnetic part 3, and the anti-shake coil 41 and the focus coil 51 can be subjected to the Ampere force respectively under the action of the magnetic field, the camera module can realize the anti-shake function and the focus function. In layman's terms, the anti-shake coil 41 and the focus coil 51 can realize the anti-shake function and the focus function of the camera module through the magnetic field generated by the common magnetic part 3. In this way, there is no need to separately set up the magnetic part 3 for realizing the anti-shake function and the magnetic part 3 for realizing the focus function in order to realize the anti-shake function and the focus function. Therefore, on the one hand, the problem of magnetic interference between the magnetic part 3 for realizing the anti-shake function and the magnetic part 3 for realizing the focus function can be avoided, so that the performance of the camera module is better, and on the other hand, the entire camera module can also be made compact.

[0170] In addition, since the camera module can realize the anti-shake function and the focusing function by deforming the liquid lens 2, that is, the liquid lens 2 integrates multiple functions, thereby further reducing the volume of the camera module.

[0171] Fig.12 is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application. Fig.12 , the electronic device includes a camera module 100.

[0172] Among them, the camera module 100 can have the same structure as any camera module 100 in the above-mentioned embodiments, and can bring the same or similar beneficial effects, and the embodiments of the present application will not be repeated here.

[0173] In the embodiment of the present application, the camera module 100 in the embodiment of the present application can avoid the problem of magnetic interference between the magnetic member 3 for realizing the anti-shake function and the magnetic member 3 for realizing the focus function, so that the performance of the camera module is better, and on the other hand, the entire camera module can be made compact. Therefore, when an electronic device includes the camera module 100, the performance of the electronic device can be better, and the space occupied by the camera module 100 in the electronic device can be reduced, so that the arrangement space of other electronic components in the electronic device is more abundant.
