DETAILED DESCRIPTION

[0052] The exemplary embodiments will be described in detail herein below with reference to the drawings. The following description relates to the drawings, in which like reference numerals refer to like elements or to similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] The technical solutions provided by the various embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0054] Figure 1 is a structural schematic of a camera module according to an exemplary embodiment Figure 1 As shown in Figure 1 The camera module 10 can include:

[0055] a base 11;

[0056] a cover 12 movably connected to the base 11 and forming a containing space with the base 11;

[0057] an anti-shake assembly 13 located in the containing space and capable of providing anti-shake processing for the camera module 10;

[0058] a sliding assembly 14 connected between the base 11 and the cover 12 and arranged to be spaced apart from the anti-shake assembly 13, and capable of causing the cover 12 to move relative to the base 11 in a first direction F1 and / or a second direction F2 by the force generated by the anti-shake assembly 13;

[0059] wherein the first direction F1 intersects the second direction F2.

[0060] In the embodiments of the present disclosure, the above-mentioned camera module can be applied to an anti-shake scene, for example, can be applied to a scene with shooting range adjustment such as object tracking.

[0061] The base can be a carrier that carries the cover shell, the anti-shake assembly, the sliding assembly, and the like.

[0062] It should be noted that the cover shell and the base can be connected in various ways to enclose the above-mentioned accommodation space, and the embodiments of the present disclosure are not limited thereto. For example, the cover shell can be connected and fixed to the base by screwing, inserting, buckling, welding, bonding, or the like.

[0063] Here, the anti-shake assembly can be a component that implements the anti-shake function of the camera module; for example, the anti-shake assembly can include an OIS coil and an OIS magnetic piece, and the like.

[0064] In the embodiments of the present disclosure, the sliding assembly can be a component that provides a moving space for the cover shell. For example, the sliding assembly can include a sliding groove and a sliding piece that can slide in the sliding groove, or the sliding groove can slide on the sliding piece; or the sliding assembly can further include a sliding rail and a protrusion that is connected to the sliding rail, and the protrusion can slide in the sliding rail.

[0065] Here, the cover shell and the base can be connected by the sliding assembly described above; the first direction and the second direction can intersect.

[0066] It should be noted that the intersection of the first direction and the second direction can be understood as the first direction and the second direction being perpendicular to each other, or the included angle between the first direction and the second direction being an acute angle, i.e., 0 to 90 degrees.

[0067] In some embodiments, the first direction and the second direction can both be directions parallel to the base, and the first direction and the second direction are perpendicular to each other; for example, the first direction can be an X-axis direction parallel to the base, and the second direction can be a Y-axis direction parallel to the base.

[0068] It should be noted that the sliding assembly can be located in the accommodation space enclosed by the cover shell and the base, or can be located at the gap between the cover shell and the base, and the embodiments of the present disclosure are not limited thereto.

[0069] It can be understood that when the above-mentioned camera module is applied to an anti-shake scene, the camera module can generate an acting force through the anti-shake assembly and the sliding assembly connected between the cover shell and the base, so that the cover shell can move relative to the base in the first direction and / or the second direction, such as the X-axis and Y-axis directions, so that the position of the lens in the camera module can be different, thereby realizing the anti-shake function of the camera module.

[0070] In some embodiments, the above-mentioned camera module may also include a focusing component for realizing the focusing function, and both the anti-shake component and the focusing component may be located in the accommodating space; the focusing component may move in a focusing direction perpendicular to the base, such as in the Z-axis direction, so that the position of the lens in the camera module may be different, thereby realizing the automatic focusing function of the camera module.

[0071] It should be noted that the structures implementing the autofocus and image stabilization functions in the aforementioned camera module may include, but are not limited to, electromagnetic structures or piezoelectric drive structures, and are not limited in the present embodiment. For example, the interaction force generated between the OIS coil and the OIS magnetic component in the image stabilization assembly can be used to drive the cover to move relative to the base to achieve the image stabilization function; alternatively, the inverse piezoelectric effect of the piezoelectric drive structure can be used to drive the focus assembly to move to achieve the autofocus function, and so on.

[0072] In some embodiments, as Figure 1 and Figure 2 As shown, the cover 12 and the base 11 each have a through hole 100 that is aligned with each other; the camera module 10 may further include:

[0073] The lens is mounted at the through hole 100 and exposed through the through hole 100 to collect external ambient light.

[0074] In this way, the lens can be installed through the through holes on the cover shell and the base to fix the position of the lens, thereby better realizing the anti-shake function of the camera module.

[0075] Here, the above lens (in Figure 1 and Figure 2 The sliding assembly (not shown) can be composed of several lenses to collect ambient light. The sliding assembly can also have a through hole aligned with the cover and the base. The lens can be exposed through the through hole in the base, the through hole in the sliding assembly, and the through hole in the cover to collect ambient light.

[0076] It can be understood that the shape of the through hole can match the shape of the lens, so that the lens can be exposed through the through hole, thereby collecting external ambient light and transmitting the ambient light to the image sensor for imaging.

[0077] In the embodiment of the present disclosure, the lens may partially protrude from the through hole in the direction toward the object being photographed by the camera module; alternatively, the lens may be completely located within the accommodation space enclosed by the cover shell and the base.

[0078] It should be noted that the specific shape of the housing formed by the cover and the base can be set according to actual application conditions and is not limited by the embodiments of the present disclosure. For example, the housing can be a rectangular parallelepiped with a through hole, or the housing can also be a cube with a through hole, etc.

[0079] Currently, as shown in Figure 3a , four suspension wires 21 can be used in a traditional camera module to support an automatic focus (AF) motor 22, which can drive the entire lens carrier to move in the X and Y axis directions parallel to the base to achieve the function of anti-shake through electromagnetic driving; however, the suspension wire used in this OIS structure has small load capacity and is prone to tilting, resulting in poor reliability of the OIS structure.

[0080] As shown in Figure 3b , a double-layer ball 23 structure can also be used in a traditional camera module, and the balls in each layer move in the X or Y axis direction in one direction to achieve the anti-shake function of the traditional camera module. However, the height space occupied by the double-layer ball design in this OIS structure is large, and the structure of the double-layer ball is complex and has low production efficiency.

[0081] Therefore, based on this, the embodiments of the present disclosure provide a camera module, which comprises: a base; a cover shell movably connected to the base and surrounding the base to form an accommodation space; an anti-shake assembly located in the accommodation space and capable of providing anti-shake processing for the camera module; a sliding assembly connected between the base and the cover shell and spaced apart from the anti-shake assembly, and capable of moving the cover shell relative to the base in a first direction and / or a second direction through the force generated by the anti-shake assembly; wherein the first direction intersects the second direction.

[0082] That is, the embodiments of the present disclosure can move the cover shell relative to the base in the first direction and / or the second direction through the sliding assembly arranged between the base and the cover shell and the force generated by the anti-shake assembly arranged apart from the sliding assembly. In this way, on the one hand, the embodiments of the present disclosure are different from the suspension line design in the related art, and can achieve anti-shake of the lens in the camera module in the first direction and / or the second direction through the sliding assembly and the anti-shake assembly, so that the lens in the camera module is less likely to tilt, thereby improving the reliability of the camera module; on the other hand, unlike the double-layer ball design in the related art, the structure of the sliding assembly in the camera module of the embodiments of the present disclosure is simplified, and the assembly and other process procedures are simple, which can effectively improve the production efficiency of the camera module and reduce the production cost.

[0083] Figure 4 is a structural schematic diagram of a camera module according to an exemplary embodiment. As shown in Figure 1 and Figure 4 , the sliding assembly 14 in the camera module provided by the embodiments of the present disclosure can comprise:

[0084] a first sliding groove 141 located on the surface of the base 11 facing the cover shell 12 and arranged in the first direction F1;

[0085] The second sliding groove 142 is located on the side of the cover shell 12 facing the base 11 and is arranged along the second direction F2.

[0086] The sliding member 143 is slidingly connected between the first sliding groove 141 and the second sliding groove 142 and partially located in the first sliding groove 141 and the second sliding groove 142.

[0087] When the sliding member 143 slides in the first sliding groove 141, the cover shell 12 and the sliding member 143 can move relative to the base 11 in the first direction F1.

[0088] When the second sliding groove 142 slides on the sliding member 143, the cover shell 12 can move relative to the base 11 in the second direction F2.

[0089] In this way, the first sliding groove can be arranged on the surface of the base facing the cover shell, the second sliding groove can be arranged on the side of the cover shell facing the base, and the sliding member can be arranged slidingly connected between the first sliding groove and the second sliding groove. By matching the sliding member with the first sliding groove and the second sliding groove, the cover shell can move relative to the base in the first direction and / or the second direction, so that the camera module can realize the anti-shake function, the height of the sliding assembly between the cover shell and the base can be reduced, the structure of the sliding assembly and the assembly process can be simplified, the production efficiency of the camera module can be effectively improved, and the production cost can be reduced.

[0090] In the embodiments of the present disclosure, the first sliding groove can be a component for the sliding member to slide in the first direction, and the second sliding groove can be a component for the sliding member to slide in the second direction. The opening direction of the first sliding groove is opposite to the opening direction of the second sliding groove, so that the sliding member can slide in the first sliding groove and the second sliding groove can slide on the sliding member.

[0091] Here, the first sliding groove can be arranged at the side edge of the base, and the second sliding groove can be arranged at the edge of the cover shell close to the base, so that the sliding assembly arranged in the camera module does not affect the light collection of the lens.

[0092] It can be understood that the first sliding groove and the base can be integrally formed, or fixedly connected by welding or screwing; the second sliding groove and the cover shell can also be integrally formed, or fixedly connected by welding or screwing.

[0093] It should be noted that the cross-sectional shape of the first sliding groove perpendicular to the first direction can be U-shaped or V-shaped, and the cross-sectional shape of the second sliding groove perpendicular to the second direction can also be U-shaped or V-shaped; in addition, the specific number of the first sliding groove and the second sliding groove can be set according to the actual application scene, and the embodiments of the present disclosure are not limited.

[0094] In the embodiment of the present disclosure, the sliding member may be a component that can slide in the first sliding groove and the second sliding groove; for example, the sliding member may include but is not limited to a sliding shaft.

[0095] It should be noted that the specific shape of the sliding part can be set according to the actual application scenario, and the embodiment of the present disclosure does not limit it.

[0096] In some embodiments, the shape of the sliding member may be a U-shaped shape; for example, the shape of the sliding member may be a square, a square with rounded corners, a rectangle, a rectangle with rounded corners, or the like.

[0097] Here, the sliding part can be integrally formed during the production process, or can be formed by welding multiple sliding shafts, etc., and the embodiments of the present disclosure do not limit this.

[0098] It can be understood that when the force generated by the anti-shake component causes part of the sliding member to slide in the first sliding groove, the cover shell and the sliding member can move in the first direction relative to the base; when the force generated by the anti-shake component causes the second sliding groove to slide on the sliding member, the cover shell fixedly connected to the second sliding groove can move in the second direction relative to the base.

[0099] In some embodiments, as Figure 4 As shown, the first direction F1 and the second direction F2 are perpendicular to each other; the sliding member 143 includes a first sliding shaft 144, a second sliding shaft 145, a third sliding shaft 146 and a fourth sliding shaft 147 connected in sequence; the first sliding shaft 144 and the third sliding shaft 146 are parallel to each other, the second sliding shaft 145 and the fourth sliding shaft 147 are parallel to each other, and the first sliding shaft 144 and the second sliding shaft 145 are perpendicular to each other;

[0100] The first sliding shaft 144 and the third sliding shaft 146 are both partially located in the first sliding groove 141 , and the second sliding shaft 145 and the fourth sliding shaft 147 are both partially located in the second sliding groove 142 .

[0101] In this way, the first sliding shaft and the third sliding shaft of the sliding member can be partially set in the first sliding groove, and the second sliding shaft and the fourth sliding shaft of the sliding member can be partially set in the second sliding groove, so that when the first sliding shaft and the third sliding shaft slide in the first sliding groove, the cover shell and the sliding member can better move in the first direction relative to the base, and when the second sliding groove slides on the second sliding shaft and the fourth sliding shaft, the cover shell can better move in the second direction relative to the base, thereby improving the reliability of the camera module while simplifying the structure of the sliding assembly in the camera module, and better reducing the height of the sliding assembly between the cover shell and the base, so as to effectively improve the production efficiency of the camera module and reduce production costs.

[0102] In the embodiments of the present disclosure, when the sliding member is in a square or rectangular shape, the sliding member can comprise a first sliding shaft, a second sliding shaft, a third sliding shaft and a fourth sliding shaft connected in sequence, and the first sliding shaft and the third sliding shaft are parallel to each other, the second sliding shaft and the fourth sliding shaft are parallel to each other, and the first sliding shaft and the second sliding shaft are perpendicular to each other; since the first sliding groove is arranged in the first direction and the second sliding groove is arranged in the second direction, the cover shell and the sliding member can be moved relative to the base in the first direction through the cooperation of the first sliding shaft, the third sliding shaft and the first sliding groove, and the cover shell can be moved relative to the base in the second direction through the cooperation of the second sliding shaft, the fourth sliding shaft and the second sliding groove.

[0103] Here, the first sliding groove can be arranged opposite to the first sliding shaft and the third sliding shaft of the sliding member, so that the first sliding shaft and the third sliding shaft can slide in the first sliding groove, and therefore the number of first sliding grooves can be at least two. For example, when the first sliding groove is two, the first sliding shaft can be partially located in one first sliding groove, and the third sliding shaft can be partially located in the other first sliding groove; when the first sliding groove is three, the first sliding shaft can be partially located in two first sliding grooves arranged opposite to the first sliding shaft, and the third sliding shaft can be partially located in the other first sliding groove, and so on.

[0104] Similarly, the second sliding groove can be arranged opposite to the second sliding shaft and the fourth sliding shaft of the sliding member, so that the second sliding groove can slide on the second sliding shaft and the fourth sliding shaft, and therefore the number of second sliding grooves can also be at least two. For example, when the second sliding groove is two, the second sliding shaft can be partially located in one second sliding groove, and the fourth sliding shaft can be partially located in the other second sliding groove; when the second sliding groove is three, the second sliding shaft can be partially located in two second sliding grooves arranged opposite to the second sliding shaft, and the fourth sliding shaft can be partially located in the other second sliding groove, and so on.

[0105] In some embodiments, as shown in Figure 1 and Figure 4 The above anti-shake assembly 13 comprises:

[0106] a first coil 131 located on the surface of the base 11 facing the cover shell 12;

[0107] a first magnetic member 132 located on the side wall of the accommodating space close to the base 11 and arranged opposite to the first coil 131;

[0108] When the first coil 131 is energized, a first acting force is generated between the first coil 131 and the first magnetic member 132 to drive the cover shell 12 and the sliding member 143 to move relative to the base 11; the direction of the first acting force is the same as the first direction F1.

[0109] In this way, the first magnetic part can be set corresponding to the first coil to utilize the first force generated between the energized first coil and the first magnetic part to drive the cover shell and the sliding part to move relative to the base, thereby realizing the anti-shake function of the camera module in the first direction.

[0110] In the disclosed embodiment, the first coil may be a coil that implements an image stabilization function for the camera module; for example, the first coil may be an OIS coil. The first magnetic member may be a permanent magnet, for example, a first image stabilization magnet (i.e., an OIS magnet). The direction of the first force may be the same as the first direction, for example, the direction of the first force may also be the X-axis direction.

[0111] Here, the first coil can generate a magnetic field when energized, ie, when current flows through it; the Lorentz force generated between the energized first coil and the first magnetic member such as a magnet can be used to drive the cover to move relative to the base.

[0112] It should be noted that the specific dimensions of the first coil and the first magnetic member can be set according to actual application conditions and are not limited in the present embodiment. For example, the dimensions of the first magnetic member can be the same as the dimensions of the first coil; or the dimensions of the first magnetic member can be different from the dimensions of the first coil; and so on.

[0113] It can be understood that when the camera module needs to be anti-shake processed, the first coil can be controlled to be in an energized state so that a first force is generated between the first coil and the first magnetic part, thereby driving the cover shell and the sliding part to move relative to the base, thereby achieving anti-shake processing of the camera module lens in the first direction.

[0114] In some embodiments, as Figure 1 and Figure 4 As shown, the anti-shake component 13 further includes:

[0115] The second coil 133 is located on the surface of the base 11 facing the cover 12 and is spaced apart from the first coil 131;

[0116] The second magnetic member 134 is located on the side wall of the accommodating space close to the base 11 and is disposed corresponding to the second coil 133;

[0117] When the second coil 133 is energized, a second force is generated between the second coil 133 and the second magnetic member 134 to drive the cover 12 to move relative to the base 11 ; the direction of the second force is the same as the second direction F2 .

[0118] In this way, the second magnetic member can be arranged corresponding to the second coil, so that the second force generated between the second coil in the powered state and the second magnetic member can be used to drive the cover shell to move relative to the base, thereby achieving the anti-shake function of the camera module in the second direction.

[0119] In the embodiments of the present disclosure, the second coil can also be a coil for achieving the anti-shake function of the camera module; for example, the second coil can also be an OIS coil. The second magnetic member can also be a permanent magnet, for example, a second anti-shake magnet (i.e., an OIS magnet). The direction of the second force can be the same as the first direction; for example, the direction of the second force can be the Y-axis direction, which is perpendicular to the direction of the first force.

[0120] It should be noted that the specific sizes of the second coil and the second magnetic member can be set according to actual application conditions, as long as the size of the second magnetic member is the same as the size of the first magnetic member, and the embodiments of the present disclosure are not limited. For example, the size of the second magnetic member can be the same as the size of the second coil; or the size of the second magnetic member can be different from the size of the second coil; and the like.

[0121] It can be understood that when the camera module needs to be processed for anti-shake, the second coil can be controlled to be in the powered state, so that the second force is generated between the second coil and the second magnetic member, thereby driving the cover shell to move relative to the base, and achieving the anti-shake processing of the lens of the camera module in the second direction.

[0122] In some embodiments, as shown in Figure 4 The first coil 131 and the second coil 133 each include at least two; the two adjacent sides of the base 11 are connected to form an included angle 111;

[0123] The at least two first coils 131 are arranged at the opposite included angles 111 of the base 11, and the at least two second coils 133 are arranged at the opposite included angles 111 of the base 11 different from the first coils 131.

[0124] In this way, the at least two first coils can be arranged at the opposite included angles of the base, and the at least two second coils can be arranged at the opposite included angles of the base different from the first coils, so that the accommodation space of the camera module can be better arranged, and the movement of the cover shell relative to the base can be more conveniently achieved by the sliding assembly.

[0125] In the embodiments of the present disclosure, the included angle can be any angle formed by the two adjacent sides of the base; for example, the angle of the included angle can be less than 90 degrees, equal to 90 degrees, or greater than 90 degrees and less than 180 degrees, etc.

[0126] It should be noted that the number of the above-mentioned angles can be determined according to the specific shape of the base in actual application; and the number of first coils and second coils can be set according to the number of the angles, which is not limited in the embodiment of the present disclosure.

[0127] Here, the first coil and the second coil can be respectively arranged at different angles of the base, and the first coil and the second coil are alternately arranged at the angles of the base, which can better generate a force between the first magnetic part and the second magnetic part, so that the cover shell can move relative to the base.

[0128] It should be noted that the specific number of the first coil and the second coil can be set according to actual application conditions, as long as the number of the first coil and the second coil is greater than or equal to two, and the embodiment of the present disclosure does not impose any restrictions.

[0129] For example, when the base is a rectangular parallelepiped with a through hole, the base can have four angles, that is, two sets of relative angles; correspondingly, the number of first coils and second coils can be two each, and the two first coils can be respectively arranged at one set of relative angles of the base, and the two second coils can be respectively arranged at another set of relative angles of the base.

[0130] like Figure 5a and 5b As shown, Figure 5a Shows a top view from the slide toward the base, Figure 5b A bottom view from the slider toward the cover is shown. Two first coils 131 are disposed at a set of relative angles on the base 11. The first coils 131 are disposed opposite the first magnetic member 132. The first coils 131 and the first magnetic member 132 can be located within the area enclosed by the slider 143. When the first coils 131 are energized, a first force between the first coils 131 and the first magnetic member 132 drives the cover 12 and the slider 143 to move in a first direction F1 relative to the base 11. Two second coils 133 are disposed at another set of relative angles on the base 11. The second coils 133 are disposed opposite the second magnetic member 134. The second coils 133 and the second magnetic member 134 can also be located within the area enclosed by the slider 143. When the second coils 133 are energized, a second force between the second coils 133 and the second magnetic member 134 drives the cover 12 to move in a second direction F2 relative to the base 11.

[0131] In some embodiments, as Figure 4 As shown, the camera module 10 further includes:

[0132] The magnetic attraction member 15 is arranged between the first coil 131 and the base 11 and between the second coil 133 and the base 11, and is used to relatively fix the base 11 and the cover 12 by the magnetic force between the first magnetic member 131 and the magnetic attraction member 15 and the magnetic force between the second magnetic member 133 and the magnetic attraction member 15.

[0133] In this way, the magnetic attraction member 15 is arranged between the first coil 131 and the base 11 and between the second coil 133 and the base 11, and is used to relatively fix the base 11 and the cover 12 by the magnetic force between the first magnetic member 131 and the magnetic attraction member 15 and the magnetic force between the second magnetic member 133 and the magnetic attraction member 15. In addition, the magnetic attraction member 15 can also enhance the magnetic field strength generated by the first coil 131 and the second coil 133 when the first coil 131 and the second coil 133 are powered on, so as to enhance the magnetic force between the first magnetic member 131 and the magnetic attraction member 15 and the magnetic force between the second magnetic member 133 and the magnetic attraction member 15.

[0134] In the embodiment of the present disclosure, the magnetic attraction member 15 can be a magnet that has an attractive force with the first magnetic member 131 and the second magnetic member 133. For example, the magnetic attraction member 15 can be a magnetic attraction piece made of a permanent magnet. In this embodiment, the magnetic pole of the first magnetic member 131 facing the base 11 can be opposite to the magnetic pole of the magnetic attraction member 15 facing the first magnetic member 131, and the magnetic pole of the second magnetic member 133 facing the base 11 can also be opposite to the magnetic pole of the magnetic attraction member 15 facing the second magnetic member 133.

[0135] Here, when the first coil 131 and the second coil 133 are not powered on by the camera module, that is, the cover 12 does not move relative to the base 11, the base 11 and the cover 12 can be relatively fixed by the magnetic force between the magnetic attraction member 15 and the first magnetic member 131 and the magnetic force between the magnetic attraction member 15 and the second magnetic member 133, so as to ensure the stability of the camera module.

[0136] When the first coil 131 and the second coil 133 are powered on by the camera module to drive the cover 12 to move relative to the base 11, the magnetic attraction member 15 can enhance the magnetic field strength generated by the first coil 131 and the second coil 133 when the first coil 131 and the second coil 133 are powered on. At this time, the magnetic attraction member 15 and the first magnetic member 131 and the magnetic attraction member 15 and the second magnetic member 133 can be controlled not to generate magnetic force, or the magnetic force generated between the magnetic attraction member 15 and the first magnetic member 131 and the magnetic attraction member 15 and the second magnetic member 133 is small, so as not to affect the movement of the cover 12 relative to the base 11.

[0137] In some embodiments, the camera module described above can further include a flexible circuit board connected to the first coil 131 and the second coil 133, and a control driving member connected to the flexible circuit board, which can be used to control the power-on and power-off of the first coil 131 and the second coil 133.

The FPC has the characteristics of high wiring density, light weight, thin thickness, and good bending property.

[0139] The control driving member can be a component for controlling the first coil and the second coil to be powered on or powered off. The control driving member can be disposed on the flexible circuit board and connected to the first coil and the second coil.

[0140] It can be understood that, after the control driving member controls the first coil and / or the second coil to be powered on at the current moment, the Lorentz force is generated between the first coil and the first magnetic member, and / or between the second coil and the second magnetic member, to drive the cover shell to move relative to the base.

[0141] Here, the control driving member can control the first coil and the second coil to be in the powered-on state or the powered-off state at the same time; or the control driving member can also control the first coil to be in the powered-on state and the second coil to be in the powered-off state, and the like, which is not limited in the embodiments of the present disclosure.
