Description

Technical Field

[0001] This application belongs to the technical field of terminals, and particularly relates to a camera module and an electronic device. Background Art

[0002] Generally, an image stabilization device can be set in an electronic device, and the lens of the electronic device is set on the image stabilization device. In this way, when the lens shakes, the image stabilization device can drive the lens to move a distance equal to the shake displacement in the direction opposite to the shake direction in a plane perpendicular to the optical axis of the lens according to the shake direction and shake displacement amount of the shake, so as to compensate for the offset generated by the lens shake. Therefore, it is possible to avoid the situation that the lens of the electronic device shakes due to the user's hand shaking during the process of using the electronic device to take pictures, and thus improve the shooting effect.

[0003] However, since there may be a situation where the shake direction of the lens of the electronic device does not lie in a plane perpendicular to the optical axis of the lens, this may cause the electronic device to be unable to compensate for the offset generated by the lens shake. Therefore, the anti-shake effect of the lens of the electronic device is poor. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a camera module and an electronic device, which can solve the problem of poor anti-shake effect of the lens of the electronic device.

[0005] In a first aspect, the embodiments of this application provide a camera module, which includes: a module body; a first carrier disposed in the module body, and a first part carrier and a second part carrier of the first carrier are connected to the module body, and a lens component is disposed on the first carrier; wherein, the first part carrier and the second part carrier can move relative to the module body; when the first part carrier moves relative to the module body, the first carrier rotates around a first axis; when the second part carrier moves relative to the module body, the first carrier rotates around a second axis; there is an included angle between the first axis and the second axis.

[0006] In a second aspect, the embodiments of this application provide an electronic device, which includes: the camera module as described in the first aspect.

[0007] In an embodiment of the present application, the camera module may include a module body and a first carrier disposed in the module body, where a first part carrier and a second part carrier of the first carrier are connected to the module body; wherein, a lens component is disposed on the first carrier, and the first part carrier and the second part carrier can move relative to the module body; when the first part carrier moves relative to the module body, the first carrier rotates around a first axis; when the second part carrier moves relative to the module body, the first carrier rotates around a second axis; there is an included angle between the first axis and the second axis. Since when the first part carrier moves relative to the module body, the first carrier can rotate around the first axis, and when the second part carrier moves relative to the module body, the first carrier rotates around the second axis, therefore, when the lens component shakes, the lens component can be rotated in one direction by the movement of the first part carrier relative to the module body, and / or the lens component can be rotated in another direction by the movement of the second part carrier relative to the module body, that is, the lens component can rotate in different directions, rather than only moving in a direction parallel to the optical axis of the lens component, so that the offset generated by the shake of the lens component in a plane not perpendicular to the lens optical axis can be compensated, and thus the anti-shake effect of the lens component can be improved.

[0008] In an embodiment of the present application, the electronic device includes the camera module in the above embodiment. Since when the first part carrier of the first carrier of the camera module moves relative to the module body of the camera module, the first carrier can rotate around a first axis, and when the second part carrier of the first carrier moves relative to the module body, the first carrier rotates around a second axis, therefore, when the lens component shakes, the lens component can be rotated in one direction by the movement of the first part carrier relative to the module body, and / or the lens component can be rotated in another direction by the movement of the second part carrier relative to the module body, that is, the lens component can rotate in different directions, rather than only moving in a direction parallel to the optical axis of the lens component, so that the offset generated by the shake of the lens component in a plane not perpendicular to the lens optical axis can be compensated, and thus the anti-shake effect of the lens component of the electronic device can be improved.

Detailed implementation manner

[0028] The following will clearly describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0030] In the description of the embodiments of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0031] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0032] The following will combine the accompanying drawings and, through specific embodiments and their application scenarios, elaborate in detail on the camera module and the electronic device provided by the embodiments of the present application.

[0033] In the related art, an image stabilization device can be provided in an electronic device, and the lens of the electronic device can be disposed on the image stabilization device. For example, as Figure 1 shown, the image stabilization device may include carrier 1 and carrier 2. A lens 3 is disposed on carrier 1, and carrier 1 is disposed on carrier 2, and carrier 1 can move in a direction perpendicular to the optical axis, and carrier 2 can move in another direction perpendicular to the optical axis. In this way, when the lens 3 shakes, the image stabilization device can control carrier 1 to move in a direction perpendicular to the optical axis of the lens and / or control carrier 2 to move in another direction perpendicular to the optical axis of the lens according to the shaking direction and the shaking displacement amount of the shake, so as to control the lens 3 to move in a plane perpendicular to the optical axis of the lens in a direction opposite to the shaking direction by a distance equal to the shaking displacement amount, so as to compensate for the offset amount generated by the lens shake, thereby avoiding the situation that the lens of the electronic device shakes due to the user's hand shake during the process of the user using the electronic device to take pictures, and further improving the shooting effect.

[0034] However, since there may be a situation where the shaking direction of the lens 3 of the electronic device does not lie in a plane perpendicular to the optical axis of the lens, this may cause the electronic device to be unable to compensate for the offset amount generated by the lens shake, and thus the anti-shake effect of the lens of the electronic device is poor.

[0035] To solve the problems existing in the related art, Figure 2 shows a schematic structural diagram of the camera module provided by the embodiments of the present application. As Figure 2 shown, the camera module provided by the embodiments of the present application may include: a module body 10; a first carrier 11, disposed in the module body 10, and a first part carrier 111 and a second part carrier 112 of the first carrier 11 are connected to the module body 10, and a lens component 12 is disposed on the first carrier 11.

[0036] In some embodiments of the present application, the above-mentioned module body 10 is used to protect other components of the camera module from external force damage.

[0037] In some embodiments of the present application, the interior of the above-mentioned module body 10 may include a cavity, so that other components of the camera module can be arranged in the cavity.

[0038] In some embodiments of the present application, the above-mentioned first carrier 11 is used to carry the lens component 12, and the shape of the first carrier 11 can be any one of the following: circular, oval, polygonal, irregular shape, etc.

[0039] In some embodiments of the present application, in combination Figure 2 , such as Figure 3 shown, a first accommodation cavity 113 is opened on the above-mentioned first carrier 11, and at least a part of the above-mentioned lens component ( Figure 3 not shown in the figure) is located in the first accommodation cavity 113, so that the lens component can be fixed to the first carrier 11.

[0040] In the embodiments of the present application, in combination Figure 2 and Figure 3 , the above-mentioned first part carrier 111 and the second part carrier 112 can move relative to the module body 10. When the first part carrier 111 moves relative to the module body 10, the first carrier 11 rotates around the first axis 13; when the second part carrier 112 moves relative to the module body 10, the first carrier 11 rotates around the second axis 14; there is an included angle between the first axis 13 and the second axis 14.

[0041] In some embodiments of the present application, the above-mentioned first part carrier 111 may be a part carrier on an edge line of the first carrier 11, and the above-mentioned second part carrier 112 may be a part carrier on another edge line of the first carrier 11. Or, the above-mentioned first part carrier 111 may be a part carrier at a corner of the first carrier 11, and the above-mentioned second part carrier 112 may be a part carrier at another corner of the first carrier 11.

[0042] It can be understood that the above-mentioned first part carrier 111 and the second part carrier 112 are different parts of the first carrier 11.

[0043] In some embodiments of the present application, the number of the above-mentioned first part carriers 111 may be at least one, and the number of the second part carriers may be at least one.

[0044] In some embodiments of the present application, the first part carrier 111 may be slidably connected to the inner side wall of the module body 10, and the second part carrier 112 may be slidably connected to the inner side wall of the module body 10.

[0045] In some embodiments of the present application, the first axis 13 may be perpendicular to the optical axis of the lens component 12, and the second axis 14 may be perpendicular to the optical axis of the lens component 12.

[0046] In some embodiments of the present application, the included angle between the first axis 13 and the second axis 14 may be 90°. It can be understood that the first axis 13 may be perpendicular to the second axis 14.

[0047] In some examples, in combination with Figure 2 and Figure 3 , as Figure 4 shown, the following are further provided in the module body 10: a first track 101, the first part of the carrier 111 is located in the first track 101 and can slide in the first track 101 in a direction perpendicular to the first axis 13; a second track 102, the second part of the carrier 112 is located in the second track 102 and can slide in the second track 102 in a direction perpendicular to the second axis 14; wherein, the first track 101 is parallel to the second track 102.

[0048] In some embodiments of the present application, the first track 101 is provided on the inner side wall of the module body 10, and the second track 102 is provided on the inner side wall of the module body 10. Alternatively, the first track 101 may be provided on other carriers within the module body 10 (such as the second carrier in the following embodiments), and the second track 102 may be provided on other carriers within the module body 10 (such as the second carrier in the following embodiments).

[0049] In some embodiments of the present application, the first track 101 may extend along the connection line direction between the lens component 12 and the bottom of the module body 10 (that is, along the direction of the optical axis of the lens component 12). It can be understood that the first part of the carrier 111 can rotate in the direction towards the lens component 12 or in the direction towards the bottom of the module body 10.

[0050] In some embodiments of the present application, the shape of the first track 101 may be arc-shaped. It can be understood that the depth of the first track 101 is arc-shaped in the connection line direction between the lens component 12 and the bottom of the module body 10, so that the first part of the carrier 111 can slide in the first track 101.

[0051] In some embodiments of the present application, the second track 102 may extend along the connection line direction between the lens component 12 and the bottom of the module body 10 (that is, along the direction of the optical axis of the lens component 12). It can be understood that the second part of the carrier 112 can rotate in the direction towards the lens component 12 or in the direction towards the bottom of the module body 10.

[0052] In some embodiments of the present application, the shape of the above-mentioned second track 102 can be arc-shaped. It can be understood that in the connection direction of the bottom of the lens component 12 and the module body 10, the depth of the second track 102 is arc-shaped, so that the second part carrier 112 can slide in the first track 102.

[0053] Thus, it can be seen that since the first track and the second track parallel to each other can be arranged in the module body, the first part carrier can move relative to the module body by sliding in the first track, and the second part carrier can move relative to the module body by sliding in the second track. Therefore, the frictional force of the first part carrier moving relative to the module body can be reduced, and the frictional force of the second part carrier moving relative to the module body can be reduced; thus, the frictional force of the first carrier rotating around the first axis and / or the second axis can be reduced.

[0054] In some embodiments of the present application, in combination with Figure 4 , as Figure 5 shown, the number of the above-mentioned first part carriers 111 is two, and the two first part carriers 111 are symmetrically distributed on both sides of the first axis 13; the number of the above-mentioned first tracks ( Figure 5 not shown in the figure) is two, and the two first tracks are symmetrically distributed on both sides of the first axis 13; wherein, each first part carrier 111 is located in a different first track.

[0055] Thus, it can be seen that since the number of the first part carriers is two, and the two first part carriers are symmetrically distributed on both sides of the first axis, when the two first part carriers move relative to the module body, the first carrier can stably rotate around the first axis; and, since each first part carrier is located in a different first track, each first part carrier can move relative to the module body by sliding in the first track. Therefore, the frictional force of moving relative to the module body can be reduced; thus, while improving the stability of the movement of the first carrier, the frictional force of the first carrier rotating around the first axis and / or the second axis can be reduced.

[0056] In some embodiments of the present application, in combination with Figure 5 , the number of the above-mentioned second part carriers 112 is two, and the two second part carriers 112 are symmetrically distributed on both sides of the second axis 14; the number of the above-mentioned second tracks ( Figure 5 not shown in the figure) is two, and the two second tracks are symmetrically distributed on both sides of the second axis 14; wherein, each second part carrier 112 is located in a different second track.

[0057] It can be seen that since the number of the second part carriers is two and the two second part carriers are symmetrically distributed on both sides of the second axis, when the two second part carriers move relative to the module body, the first carrier can rotate stably around the second axis; and, since each second part carrier is located in a different second track, each second part carrier can move relative to the module body by sliding in the second track, so that the friction force during the movement relative to the module body can be reduced; thus, while improving the movement stability of the first carrier, the friction force when the first carrier rotates around the first axis and / or the second axis can be reduced.

[0058] In some embodiments of the present application, in combination with Figure 4 , such as Figure 6 shown, a first rolling member 103 is provided between the inner wall of the first track 101 and the first part carrier 111; a second rolling member 104 is provided between the inner wall of the second track 102 and the second part carrier 112.

[0059] In some embodiments of the present application, the above-mentioned first rolling member 103 can be any one of the following: ball, pulley, etc., and the number of the first rolling members 103 can be at least one.

[0060] In some embodiments of the present application, the above-mentioned second rolling member 104 can be any one of the following: ball, pulley, etc., and the number of the second rolling members 104 can be at least one.

[0061] It can be seen that since a first rolling member is provided between the inner wall of the first track and the first part carrier, when the first part carrier slides in the first track, the friction force between the first part carrier and the inner wall of the first track can be rolling friction instead of sliding friction, so that the friction force between the first part carrier and the inner wall of the first track can be reduced; and, since a second rolling member is provided between the inner wall of the second track and the second part carrier, when the second part carrier slides in the second track, the friction force between the second part carrier and the inner wall of the second track can be rolling friction instead of sliding friction, so that the friction force between the second part carrier and the inner wall of the second track can be reduced; thus, the friction force when the first carrier rotates around the first axis and / or the second axis can be reduced.

[0062] Next, taking a possible structure in the embodiments of the present application as an example, the specific process of the first carrier 11 rotating around the first axis 13 and the second axis 14 will be exemplified.

[0063] In one example, such as Figure 7 shown, the first part carrier 111 can move in the direction towards the bottom of the module body 10 (i.e., Figure 7in the downward direction) slide, the second part of the carrier 112 can slide in the direction towards the lens component 12 (i.e., Figure 7 in the upward direction) slide, that is to say, the first carrier 11 slides along Figure 7 in the counterclockwise direction. Or, the first part of the carrier 111 can slide in the direction towards the lens component 12 (i.e., Figure 7 in the upward direction) slide, the second part of the carrier 112 can slide in the direction towards the bottom of the module body 10 (i.e., Figure 7 in the downward direction) slide, that is to say, the first carrier 11 slides along Figure 7 in the clockwise direction.

[0064] Taking that the first part of the carrier 111 can slide in the direction towards the bottom of the module body 10 (i.e., Figure 7 in the downward direction) slide, the second part of the carrier 112 can slide in the direction towards the lens component 12 (i.e., Figure 7 in the upward direction) slide as an example, at this time the first carrier 11 rotates along both the first axis and the second axis at the same time, that is to say, the first carrier 11 rotates Figure 7 in the counterclockwise direction, and the position of the first carrier 11 after rotation is as shown in Figure 8 .

[0065] It should be noted that the first carrier 11 may also rotate only around the first axis 13 or the second axis 14, Figure 7 and Figure 8 shows the first carrier 11 rotating around the first axis 13 and the second axis 14 for illustration.

[0066] It can be understood that since the first carrier 11 can rotate around the first axis 13 and / or the second axis 14, therefore, it can be regarded that the first carrier 11 can rotate around the intersection point of the first axis 13 and the second axis 14, and this intersection point can be the center point of the first carrier 11.

[0067] As can be seen from the above, in the embodiment of the present application, when under an external force, for example, under the action of gravity or the driving force of other components of the camera module, when the first part of the first carrier 11, i.e., the carrier 111, rotates around the first axis 13, the first carrier 11 can rotate around the first axis 13, so that the lens component 12 can rotate around the first axis 13; when the second part of the first carrier 11, i.e., the carrier 112, rotates around the second axis 14, the first carrier 11 can rotate around the second axis 14, so that the lens component 12 can rotate around the second axis 14; that is to say, the lens component 12 can rotate in different directions, rather than, as in the related art, only being able to move in a plane perpendicular to the optical axis of the lens component 12. Therefore, when the jitter direction of the lens component 12 does not lie in the plane perpendicular to the optical axis of the lens component 12, the offset caused by the jitter of the lens component 12 can still be compensated.

[0068] The embodiment of the present application provides a camera module, which may include a module body and a first carrier disposed in the module body, wherein the first part and the second part of the carrier are connected to the module body; wherein, a lens component is disposed on the first carrier, and the first part and the second part of the carrier can move relative to the module body; when the first part of the carrier moves relative to the module body, the first carrier rotates around the first axis; when the second part of the carrier moves relative to the module body, the first carrier rotates around the second axis; there is an included angle between the first axis and the second axis. Since when the first part of the carrier moves relative to the module body, the first carrier can rotate around the first axis, and when the second part of the carrier moves relative to the module body, the first carrier rotates around the second axis, therefore, when the lens component jitters, the lens component can be rotated in one direction by the relative movement of the first part of the carrier relative to the module body, and / or the lens component can be rotated in another direction by the relative movement of the second part of the carrier relative to the module body, that is, the lens component can rotate in different directions, rather than only moving in a direction parallel to the optical axis of the lens component, so that the offset caused by the jitter of the lens component when it does not occur in the plane perpendicular to the optical axis of the lens can be compensated, and thus the anti-shake effect of the lens component can be improved.

[0069] Moreover, since in the embodiment of the present application, only one carrier (i.e., the first carrier) is used to carry the lens component, the offset caused by the jitter of the lens component when it does not occur in the plane perpendicular to the optical axis of the lens can be compensated, without the need to use multiple carriers to carry the lens component as in the related art. Therefore, the gravity of the carrier carrying the lens component can be reduced, and thus the resistance to the rotation of the first carrier can be reduced.

[0070] Of course, in order to drive the rotation of the first carrier 11 more precisely, a driving component (such as the coil and magnetic component in the following embodiments) can also be provided in the camera module to determine the rotation of the first carrier 11 according to the offset of the lens component 12. The following will give examples for illustration.

[0071] In some embodiments of the present application, in combination with Figure 2 , as Figure 9 shown, the above camera module may further include: a first magnetic component 15 disposed on the first partial carrier 111; a first coil 16 disposed in the module body 10; wherein, when the first coil 16 is energized, a first magnetic force between the first coil 16 and the first magnetic component 15 drives the first partial carrier 111 to move relative to the module body 10.

[0072] In some embodiments of the present application, the above first magnetic component 15 may be any one of the following: a magnet, a magnetic stone, a coil, etc. The first magnetic component 15 may be disposed on the surface of the first partial carrier 111 close to the lens component 12 or on the surface away from the lens component 12.

[0073] In some embodiments of the present application, the above first coil 16 may be disposed on the inner side wall of the module body 10, and the first coil 16 may be opposite to the first magnetic component 15. Herein, the first coil 16 being opposite to the first magnetic component 15 can be understood as: the projection of the first magnetic component 15 on the inner side wall of the module body 10 where the first coil 16 is disposed at least partially overlaps with the first magnetic component 15.

[0074] In some embodiments of the present application, when the first coil 16 is energized, a first magnetic force (such as magnetic attraction or magnetic repulsion) may be generated between the first coil 16 and the first magnetic component 15, and the first magnetic force may be a Lorentz force, so that the first partial carrier 111 can be driven to move relative to the module body 10 through the first magnetic force.

[0075] Thus, it can be seen that since a first magnetic component and a first coil can be provided in the camera module, when it is necessary to drive the rotation of the first carrier, the rotation of the first carrier can be accurately controlled by energizing the first coil. Therefore, the effect of compensating the lens component can be improved, and thus, the anti-shake effect of the lens component can be improved.

[0076] In some embodiments of the present application, in combination with Figure 9 , as Figure 10 shown, the number of the above first partial carriers 111 is two, and the two first partial carriers 111 are symmetrically distributed on both sides of the first axis 13; the number of the above first magnetic components 15 is two, and the above first coil ( Figure 10The number of them (not shown in the figure) is two. Each first magnetic member 15 is located on a different first part carrier 111. When at least two first coils are energized, the first magnetic force between each first coil and a first magnetic member 15 drives a first part carrier 111 to move relative to the module body 10.

[0077] In some embodiments of the present application, the magnetic field directions of the at least two first magnetic members 15 may be the same or different.

[0078] In some embodiments of the present application, at least two first coils 16 may be disposed on different inner sidewalls of the module body 10, and each first coil 16 is respectively opposite to a first magnetic member 15. The at least two first coils 16 may be energized with current in the same direction or in different directions. Herein, each first coil 16 being opposite to a first magnetic member 15 can be understood as: the projection of a first magnetic member 15 on the inner sidewall of the module body 10 where a first coil 16 is disposed at least partially overlaps with the first magnetic member 15.

[0079] In some examples, when the magnetic field directions of the at least two first magnetic members 15 are the same, a first direction of current may be passed through one first coil 16 and a second direction of current may be passed through the other first coil 16. In this way, the first magnetic force (such as magnetic attraction or magnetic repulsion) generated by one first magnetic member 15 is opposite to the first magnetic force (such as magnetic repulsion or magnetic attraction) that the other first magnetic member 15 can generate, so that the first carrier 11 can rotate around the first axis 13. Herein, the first direction and the second direction are opposite.

[0080] In other examples, when the magnetic field directions of the at least two first magnetic members 15 are opposite, a first direction (or a second direction) of current may be passed through the two first coils 16. In this way, the first magnetic force (such as magnetic attraction) generated by one first magnetic member 15 is opposite to the first magnetic force (such as magnetic repulsion) that the other first magnetic member 15 can generate, so that the first carrier 11 can rotate around the first axis 13.

[0081] It can be seen that since a first magnetic member can be respectively disposed on each first part carrier, when the first coil is energized, the first coil can stably drive the two first part carriers to slide. Therefore, the first carrier can be stably rotated around the first axis and / or the second axis.

[0082] In some embodiments of the present application, in combination with Figure 9, the camera module provided by the embodiment of the present application may further include: a second magnetic member 17 disposed on the second part of the carrier 112; a second coil 18 disposed in the module body 10; wherein, when the second coil 18 is energized, the second magnetic force between the second coil 18 and the second magnetic member 17 drives the second part of the carrier 112 to move relative to the module body 10.

[0083] In some embodiments of the present application, the second magnetic member 17 may be any one of the following: a magnet, a magnetic stone, a coil, etc. The second magnetic member 17 may be disposed on the surface of the second part of the carrier 112 close to the lens component 12 or on the surface away from the lens component 12.

[0084] In some embodiments of the present application, the second coil 18 may be disposed on the inner wall of the module body 10, and the second coil 18 may be opposite to the second magnetic member 17. Wherein, the second coil 18 being opposite to the second magnetic member 17 may be understood as: the projection of the second magnetic member 17 on the inner side wall of the module body 10 where the second coil 18 is disposed at least partially overlaps with the second magnetic member 17.

[0085] In some embodiments of the present application, when the second coil 18 is energized, a second magnetic force (such as magnetic attraction or magnetic repulsion) may be generated between the second coil 18 and the second magnetic member 17. The second magnetic force may be a Lorentz force, so that the second part of the carrier 112 can be driven to move relative to the module body 10 through the second magnetic force.

[0086] It can be seen that since a second magnetic member and a second coil can be provided in the camera module, when it is necessary to drive the first carrier to rotate, the first carrier can be accurately controlled to rotate by energizing the second coil. Therefore, the effect of compensating the lens component can be improved, and thus the anti-shake effect of the lens component can be improved.

[0087] In some embodiments of the present application, in combination with Figure 10 , the number of the second parts of the carrier 112 is two, and the two second parts of the carrier 112 are symmetrically distributed on both sides of the second axis 14; the number of the second magnetic members 17 is two, and the number of the second coils ( Figure 10 not shown in the figure) is two; wherein, each second magnetic member 17 is located on a different second part of the carrier 112. When at least two second coils are energized, the second magnetic force between each second coil and a second magnetic member 17 drives a second part of the carrier 112 to move relative to the module body 10.

[0088] In some embodiments of the present application, the magnetic field directions of the at least two second magnetic members 17 may be the same or different.

[0089] In some embodiments of the present application, at least two second coils 18 may be disposed on different inner sidewalls of the module body 10, and each second coil 18 is respectively opposite to a second magnetic member 17. The at least two second coils 18 may conduct currents in the same direction or in different directions. Herein, each second coil 18 being opposite to a second magnetic member 17 may be understood as: the projection of a second magnetic member 17 on the inner sidewall of the module body 10 where a second coil 18 is disposed at least partially overlaps with the second magnetic member 17.

[0090] In some examples, when the magnetic field directions of at least two second magnetic members 17 are the same, a current in a third direction may be conducted to one second coil 18, and a current in a fourth direction may be conducted to another second coil 18. In this way, the second magnetic force (such as magnetic attraction or magnetic repulsion) generated by one second magnetic member 17 is opposite to the second magnetic force (such as magnetic repulsion or magnetic attraction) that another second magnetic member 17 can generate, so that the first carrier 11 can rotate around the second axis 14. Herein, the third direction and the fourth direction are opposite.

[0091] In other examples, when the magnetic field directions of at least two second magnetic members 17 are opposite, a current in a third direction (or a fourth direction) may be conducted to the two second coils 18. In this way, the second magnetic force (such as magnetic attraction) generated by one second magnetic member 17 is opposite to the second magnetic force (such as magnetic repulsion) that another second magnetic member 17 can generate, so that the first carrier 11 can rotate around the second axis 14.

[0092] Thus, it can be seen that since a second magnetic member can be respectively disposed on each second partial carrier, when the second coil is energized, the second coil can stably drive the two second partial carriers to slide. Therefore, the first carrier can be stably rotated around the first axis and / or the second axis.

[0093] In some embodiments of the present application, as Figure 11As shown, a first detection component 21 and a second detection component 22 are further provided in the module body 10. The first detection component 21 is used to detect the first magnetic flux change parameter corresponding to the first magnetic component 15, and the second detection component 22 is used to detect the second magnetic flux change parameter corresponding to the second magnetic component 17. Thus, when the camera module is disposed in an electronic device, in the case where the lens component 12 shakes, the first detection component 21 and / or the second detection component 22 can respectively detect the first magnetic flux change parameter and / or the second magnetic flux change parameter. In this way, the electronic device can accurately determine the first offset amount of the lens component 12 rotating around the first axis 13 and / or the second offset amount of the lens component 12 rotating around the second axis 14 according to the first magnetic flux change parameter and / or the second magnetic flux change parameter, and energize the first coil 16 and / or the second coil 18 according to the first offset amount and / or the second offset amount, so as to drive the first part carrier 111 to move a third offset amount in a direction opposite to the first offset amount and / or drive the second part carrier 112 to move a fourth offset amount in a direction opposite to the second offset amount, thereby compensating for the offset amount generated by the lens component 12 shaking when not in a plane perpendicular to the lens optical axis.

[0094] In some examples, the above-mentioned first detection component 21 and second detection component 22 may both be Hall sensors. Of course, the first detection component 21 and the second detection component 22 may also be other sensors, and the embodiments of the present application do not limit this.

[0095] In some examples, at least one correspondence is stored in the electronic device, and this correspondence is the correspondence between the magnetic flux change parameter and the offset amount. Thus, the electronic device can determine the first offset amount corresponding to the first magnetic flux change parameter according to at least one correspondence, and determine the offset amount with the same offset value and the opposite direction as the first offset amount as the third offset amount; moreover, the electronic device can determine the second offset amount corresponding to the second magnetic flux change parameter according to at least one correspondence, and determine the offset amount with the same offset value and the opposite direction as the second offset amount as the fourth offset amount.

[0096] In some examples, the electronic device can energize the first coil 16 with a current of a corresponding direction and magnitude according to the direction and offset value of the third offset amount, so as to drive the first part carrier 111 to move a third offset amount in a direction opposite to the first offset amount; moreover, the electronic device can energize the second coil 18 with a current of a corresponding direction and magnitude according to the direction and offset value of the fourth offset amount, so as to drive the second part carrier 112 to move a fourth offset amount in a direction opposite to the second offset amount.

[0097] It can be seen that since the first detection component and the second detection component can be provided in the module body, when the lens component shakes, the first offset amount of the lens component shaking can be accurately determined through the magnetic flux change parameter detected by the first detection component, and / or, the second offset amount of the lens component shaking can be accurately determined through the magnetic flux change parameter detected by the first detection component; in this way, the movement of the first part of the carrier can be controlled by energizing the first coil to compensate for the first offset amount; and / or, the movement of the first part of the carrier can be controlled by energizing the second coil to compensate for the second offset amount; therefore, the offset amount generated by the lens component shaking when not in the plane perpendicular to the optical axis of the lens can be accurately compensated.

[0098] In some embodiments of the present application, in combination with Figure 2 , as Figure 12 shown, the above-mentioned module body 10 includes: a module housing 19; a second carrier 20, the first part of the carrier 111 and the second part of the carrier 112 are connected to the second carrier 20 and can move relative to the second carrier 20, and the second carrier 20 is also connected to the module housing 19; wherein, the second carrier 20 can move relative to the module housing 19 along the direction of the optical axis of the lens component 12.

[0099] It can be understood that the above-mentioned module housing 19 encloses the internal cavity of the module body 10, that is to say, other components of the camera module are arranged in the module housing 19.

[0100] In some embodiments of the present application, the above-mentioned second carrier 20 is used to carry the first carrier 11, and the second carrier 20 can be slidably connected to the inner side wall of the module housing 19.

[0101] In some examples, as Figure 13 shown, a second accommodation cavity 201 is provided and opened on the second carrier 20, and the second accommodation cavity 201 is used to accommodate the first carrier 11. The above-mentioned first track 101 and second track 102 can be arranged on the second carrier 20. For example, the first track 101 and the second track 102 can be arranged on non-adjacent parts of the inner side wall of the second carrier 20. Among them, in Figure 13 the second track 102 can be arranged at the A part (i.e., the A part in Figure 13 ) of the inner side wall of the second carrier 20. The view of the first carrier 11 located in the second accommodation cavity 201 is as Figure 14 shown. It can be understood that from the perspective of Figure 14 , the second carrier 20 is located below the first carrier 11.

[0102] Among them, Figure 15 shows an enlarged schematic view of the A part in Figure 13 , as Figure 15As shown, the shape of the second track 102 can be arc-shaped. The depth of the second track 102 is arc-shaped in the direction of the connection line between the bottom of the lens component 12 and the module body 10.

[0103] In some examples, in combination with Figure 12 , a third track 23 is provided on the inner side wall of the module housing 19. The third track 23 extends along the optical axis direction of the lens component 12, and at least part of the second carrier 20 is located within the third track 23 and can slide within the third track 23. Thus, the second carrier 20 can move relative to the module housing 19 along the optical axis direction of the lens component 12. Among them, the above-mentioned third track 23 can be a linear track. A third rolling member 24 is provided between the inner wall of the third track 23 and the second carrier 20.

[0104] It can be understood that the third rolling member 24 can be arranged within the third track 23.

[0105] Here, the third rolling member 24 can be any one of the following: ball, pulley, etc. The number of the first rolling members 103 can be at least one.

[0106] Thus, it can be known that since a third rolling member is provided between the inner wall of the third track and the second carrier, when the second carrier slides within the third track, the friction force between the second carrier and the inner wall of the third track can be rolling friction force instead of sliding friction force. Therefore, the friction force between the second carrier and the inner wall of the third track can be reduced to reduce the resistance of the second carrier to move relative to the module housing along the optical axis direction of the lens component.

[0107] In some examples, in combination with Figure 12 , the above camera module can further include: a third magnetic member 25, arranged on the second carrier 20; a third coil 26, arranged on the module housing 19; among them, when the second coil 26 is energized, the third magnetic force between the third coil 26 and the third magnetic member 25 drives the second carrier 20 to move relative to the module housing 19 along the optical axis direction of the lens component 12.

[0108] Among them, the above-mentioned third magnetic member 25 can be any one of the following: magnet, magnetic stone, coil, etc. The third magnetic member 25 can be arranged on the surface of the second carrier 20 close to the lens component 12 or on the surface away from the lens component 12.

[0109] Among them, the above-mentioned third coil 26 can be arranged on the inner side wall of the module housing 19, and the third coil 26 can be opposite to the third magnetic member 25. The fact that the third coil 26 is opposite to the third magnetic member 25 can be understood as: the projection of the third magnetic member 25 on the inner side wall of the module housing 19 where the third coil 26 is arranged overlaps at least partially with the third magnetic member 25.

[0110] Among them, when the third coil 26 is energized, a third magnetic force (such as magnetic attraction or magnetic repulsion) can be generated between the third coil 26 and the third magnetic member 25. The third magnetic force can be a Lorentz force, so that the second carrier 20 can be driven to move relative to the module housing 19 by the third magnetic force.

[0111] As can be seen, since the module body can include a second carrier, and the second carrier can move relative to the module housing along the optical axis direction of the lens component, the focal length of the lens component can be accurately controlled by controlling the movement of the second carrier along the optical axis direction. Therefore, the zoom operation can be accurately achieved.

[0112] Figure 16 The structural schematic diagram of the electronic device provided by the embodiment of the present application is shown. As Figure 16 shown, the electronic device 30 provided by the embodiment of the present application may include: the camera module 31 in the above embodiment.

[0113] In some embodiments of the present application, the above electronic device 30 may be any one of the following: a mobile phone, a personal computer PC, a personal game console, a drone, etc. Of course, the electronic device may also be other devices, and the embodiments of the present application do not limit this.

[0114] The embodiment of the present application provides an electronic device, which includes the camera module in the above embodiment. Since when the first part of the first carrier of the camera module moves relative to the module body of the camera module, the first carrier can rotate around the first axis, and when the second part of the first carrier moves relative to the module body, the first carrier rotates around the second axis. Therefore, when the lens component shakes, the lens component can be rotated in one direction by the movement of the first part of the carrier relative to the module body, and / or the lens component can be rotated in another direction by the movement of the second part of the carrier relative to the module body, that is, the lens component can rotate in different directions, rather than only move in the direction parallel to the optical axis of the lens component. Thus, the offset generated by the shake of the lens component not in the plane perpendicular to the lens optical axis can be compensated, and further the anti-shake effect of the lens component of the electronic device can be improved.
