The camera module 100 and the electronic device 200 according to the embodiments of the present application are described below with reference to fig. 1 to 12.
As shown in fig. 1, the camera module provided by the embodiment of the application can be applied to electronic equipment. The electronic device can be a mobile phone, a tablet personal computer, a smart bracelet and the like.
In an embodiment of the present application, the camera module includes: the lens comprises a shell 3, a liquid lens 2, a rotating structure 11 and a connecting rod 13.
In the embodiment of the present application, as shown in fig. 1 and 2, the liquid lens 2 is disposed in the housing 3; the rotating structure 11 is connected with the shell 3; the first end of the connecting rod 13 is connected with the rotating structure 11, and the second end is in transmission connection with the liquid lens 2. Wherein, in the case that the rotating structure 11 rotates, the second end of the connecting rod 13 moves in the optical axis direction of the liquid lens 2 in the housing 3, and presses the liquid lens 2 during the movement to adjust the focal length of the liquid lens 2.
In the embodiment of the present application, the specific positional structural relationship between the liquid lens 2 and the housing 3 includes, but is not limited to, the following ways: the liquid lens 2 may be disposed in a cavity formed by the housing 3; or the liquid lens 2 may be connected to the inner wall of the housing 3, for example, to the middle of the inner wall of the housing 3 or to the inner wall of the housing 3 near the end of the housing 3; or the liquid lens 2 is provided at one end of the housing 3.
It will be appreciated that when the rotating structure 11 is under the action of the driving force, the rotating structure 11 can drive the connecting rod 13 to move through the first end of the connecting rod 13 during the rotation process, and during the movement process of the connecting rod 13, the second end of the connecting rod 13 reciprocates (i.e. reciprocates) in the housing 3 along the optical axis direction of the liquid lens 2, and during the reciprocation process, the liquid lens 2 can be extruded to deform (i.e. the focal length of the liquid lens 2 changes) through the transmission. The degree of deformation generated by squeezing the liquid lens 2 is different due to the different driving forces, and then the focal length of the camera module is changed by applying different driving forces to the rotating structure 11 (i.e. different driving forces correspond to different focuses of the liquid lens 2).
That is, when the camera module is used for photographing or shooting video, the second end of the driving connecting rod 13 is applied to the rotating structure 11 to reciprocate along the optical axis direction of the liquid lens 2, the liquid lens 2 is extruded to deform through transmission in the reciprocation process, and after the shape is changed, the focal position of the liquid lens 2 moves, so that focusing of the camera can be realized.
Illustratively, the rotating structure 11 may be directly connected to the housing 3 by a sliding structure or a rolling structure; or the rotating structure 11 is connected to the housing 3 by means of a mounting portion (e.g. a bracket) on which the rotating structure 11 can rotate. The rotating structure 11 may be connected to the housing 3 through other connection structures, so long as the rotating structure 11 can drive the connecting rod 13 to move in the rotating process, and the second end of the connecting rod 13 can reciprocate in the housing 3 along the optical axis direction of the liquid lens 2, and the specific connection structure between the rotating structure 11 and the housing 3 may be selected according to practical requirements, which is not limited in the embodiment of the present application.
It will be appreciated that the first end of the connecting rod 13 may be rotatably connected to the rotating structure 11, so that, when the rotating structure 11 rotates, the angle between the connecting rod 13 and the rotating structure 11 may change, for example, the connecting rod 13 changes from vertical to inclined, so that, when the rotating structure 11 rotates, the second end of the connecting rod 13 approaches or departs from the liquid lens 2 along the optical axis direction of the liquid lens 2, and during the process of approaching or departs from the liquid lens 2, the connecting rod 13 presses the liquid lens 2 through transmission, and as the rotating structure 11 continues to rotate, the connecting rod 13 continues to press the liquid lens 2 through transmission, and the focus of the liquid lens 2 moves.
Illustratively, as shown in fig. 1 and 2, the rotating structure 11 may be disposed at one end (e.g., an upper end) of the housing 3, and the liquid lens 2 may be disposed at the other end (e.g., an inner wall of the housing 3 is close to a lower end of the housing 3) of the housing 3; the first end of the connecting rod 13 (for example, the upper end of the connecting rod 13) is rotatably connected with the rotating structure 11, and the second end (for example, the lower end of the connecting rod 13) is in transmission connection with the liquid lens 2. Therefore, when the rotating structure 11 rotates, the connecting rod 13 can be switched between the vertical state and the inclined state, and in the switching process, the connecting rod 13 is transmitted to press the liquid lens 2 to deform, so that the focal length of the liquid lens 2 is changed.
In the embodiment of the present application, the housing 3 may be tubular, for example, circular, and the shape of the housing 3 may be changed according to different situations, which is not limited in the embodiment of the present application.
The camera module provided by the embodiment of the application comprises a shell, a liquid lens, a rotating structure and a connecting rod. The liquid lens is arranged in the shell, the rotating structure is connected with the shell, the first end of the connecting rod is connected with the rotating structure, and the second end of the connecting rod is in transmission connection with the liquid lens. According to the embodiment of the application, the driving force is used for controlling the rotating structure to drive the moving position of the second end of the connecting rod, and the connecting rod is used for extruding the liquid lens to generate different deformation degrees on the physical structure through transmission through different moving positions, so that zooming (namely movement of the focal point position) of the camera module is realized.
Optionally, in an embodiment of the present application, the camera module further includes a driving unit, and the driving unit may be connected to the rotating structure 11 and configured to provide a driving force to the rotating structure 11.
In the embodiment of the present application, the driving unit may be mounted on the housing 3, and if the design of the camera module is considered to be thin, the driving unit may not be mounted on the housing 3, and only needs to be connected to the rotating structure 11 to drive the rotating structure 11 to rotate (i.e. only needs to provide driving force for the rotating structure 11).
The drive unit may be an electric drive unit, or a mechanical drive unit, or a manual drive unit, or other possible drive units, for example, and embodiments of the present application are not limited thereto, but are illustrated only by way of example as electrically driven units.
Optionally, in the embodiment of the present application, the camera module further includes an extrusion member, the extrusion member 12 is disposed in the housing, the extrusion member 12 is connected to the second end of the connecting rod 13, the connecting rod 13 drives the extrusion member 12 to move, and the extrusion member 12 extrudes the liquid lens to adjust the focal length of the liquid lens. That is, the second end of the connecting rod 13 can drive the extrusion 12 to extrude the liquid lens 2 through transmission to change the focal length.
It will be appreciated that the extrusion 12 may be located between the connecting rod 13 and the liquid lens 2, the extrusion 12 being adapted to compress the liquid lens 2 for deformation.
Specifically, when the rotating structure 11 is under the action of the driving force, the rotating structure 11 can drive the extrusion member 12 to reciprocate in the housing 3 along the optical axis direction of the liquid lens 2 through the connecting rod 13 in the rotating process, and the extrusion member 12 can extrude the liquid lens 2 to deform in the reciprocating process. The degree of deformation of the extrusion 121 extruded by the liquid lens 2 is different according to the magnitude of the driving force, and then the focal length of the camera module is changed (i.e. different driving forces correspond to different focuses of the liquid lens 2).
That is, by applying a driving force to the rotating structure 11, the rotating structure 11 rotates, and the pressing member 12 is driven by the connecting rod 13 to press the liquid lens 2 to deform, and after the shape is changed, the focal position of the liquid lens 2 moves.
Illustratively, the rotational connection between the second end of the connecting rod 13 and the extrusion 12 may be: the hinge-type rotational connection, or the snap-in-place rotational connection, or other possible rotational connection, embodiments of the present application are not limited in this regard.
Illustratively, as shown in fig. 2 and 3, a rotating structure 11 is provided at an upper end of the housing 3, the liquid lens 2 is provided on an inner wall of the housing 3 near a lower end of the housing 3, a second end of a link 13 is rotatably connected to an upper end of the pressing member 12, and a lower end of the pressing member 12 faces the liquid lens 2. Therefore, when the rotating structure 11 rotates, the pressing piece 12 can be driven to move upwards or downwards (namely, to move close to or away from the liquid lens 2) through the connecting rod 13, and in the process of downward movement of the pressing piece 12, the pressing piece 12 is close to the liquid lens 2 and can be in contact with the liquid lens 2, and along with continuous rotation of the rotating structure 11, the pressing piece 12 can continuously press the liquid lens 2, and the focus of the liquid lens 2 can move.
For example, as shown in fig. 4 and 5, referring to fig. 1 and 2, a rotating structure 11 is provided on the housing 3, and an upper end of the pressing member 12 is rotatably connected to the rotating structure 11 through a link 13.
When the camera module provided by the embodiment of the application is used for shooting, the driving unit drives the rotating structure 11 to rotate in a first direction (for example, clockwise), the extrusion piece 12 moves downwards (i.e., approaches the liquid lens 2), and when the camera module rotates to a first state, the connecting rod 13 is perpendicular to the extrusion piece 12 (i.e., the connecting rod 13 is in a vertical state, and an included angle between the connecting rod 13 and the extrusion piece 12 is a right angle), at this time, the distance between the extrusion piece 12 and the rotating structure 11 is the largest, the extrusion piece 12 can extrude the liquid lens 2 to the greatest extent, and the deformation of the liquid lens 2 is the largest in this state.
If the camera module needs to be zoomed, the focal position of the liquid lens 2 is adjusted to move in the opposite direction, the driving unit drives the rotating structure 11 to rotate in a second direction (e.g. counterclockwise direction) opposite to the first direction, the pressing member 12 moves upward (i.e. away from the liquid lens 2), when the rotating structure 11 drives the pressing member 12 to move upward to the second state through the connecting rod 13, referring to fig. 5, the included angle between the connecting rod 13 and the pressing member 12 is an acute angle (i.e. the connecting rod 13 is in an inclined state, and the connecting rod 13 and the pressing member 12 are in a non-perpendicular relationship), and the distance between the pressing member 12 and the rotating structure 11 is reduced. Therefore, the focal position of the liquid lens 2 can be conveniently adjusted, and the zooming of the camera module is further realized.
It should be noted that, by controlling the length of the connecting rod 13, the maximum pressing force of the pressing member 12 on the liquid lens 2 (i.e., the maximum deformation of the liquid lens 2) may be controlled. Furthermore, under the premise of ensuring normal zooming of the liquid lens 2, according to the difference of the maximum extrusion force which can be borne by different liquid lenses 2, connecting rods 13 with different lengths can be arranged for different liquid lenses 2, and then the extrusion force which can be borne by the liquid lenses 2 is controlled in a controllable range, so that the service life of the liquid lenses 2 can be prolonged under the condition of meeting shooting requirements.
For example, the number of the links 13 may be at least two, and the links 13 may be uniformly arranged (for example, circumferentially uniformly arranged), so that a driving force can be uniformly provided to the pressing member 12 in the circumferential direction by the links 13, and a pressing force can be uniformly applied to the liquid lens 2 in the circumferential direction by the pressing member 12. Specifically, referring to fig. 2 and 6, there are two links 13, and the two links 13 are uniformly arranged along the circumference of the pressing member 12.
Illustratively, the extrusion 12 may be annular, such as annular, or square annular; alternatively, the extrusion 12 may include a plurality of extrusion sheets, which may be uniformly circumferentially disposed. The liquid lens may protrude from the inner circumference of the annular pressing member during the movement of the pressing member 12.
Illustratively, the contour shape of the extrusion 12 may coincide with the contour shape of the liquid lens 2, and the center of the orthographic projection of the extrusion 12 coincides with the center of the orthographic projection of the liquid lens 2.
Alternatively, in the embodiment of the present application, the pressing member 12 has a ring shape, and the pressing member 12 is slidably connected to the inner wall of the housing 3.
Illustratively, the sliding connection between the extrusion 12 and the inside wall of the housing 3 may include, but is not limited to, the following: the extrusion 12 is slidably connected with the inner wall (i.e., the inner side wall) of the housing 3 through a sliding groove, and the extrusion 12 is slidably connected with the inner side wall of the housing 3 through a sliding rail.
Through the above-mentioned several sliding connection modes, in the extrusion 12 sliding process, extrusion 12 can be along the direction motion of sliding tray or slide rail to make extrusion 12 can extrude liquid lens 2 and produce different deformation in the motion process, realize focusing to liquid lens 2.

In another example, the positions of the first limiting groove 4 and the boss 5 may be interchanged, that is, the first limiting groove 4 is disposed on the periphery of the pressing member 12, the boss 5 is disposed on the inner wall of the housing 3, and the boss extends along the optical axis direction of the liquid lens, and likewise, the boss 5 is snapped into the first limiting groove 4, so that the boss 5 will reciprocate (e.g., move upward or downward) in the first limiting groove 4 as the pressing member 12 approaches or moves away from the liquid lens 2.
In the two examples, through the cooperation between the first limit groove 4 and the boss 5, the limit effect on the extrusion piece 12 can be realized in the process that the extrusion piece 12 is close to or far away from the liquid lens 2, namely, the extrusion piece 12 is ensured to be close to or far away from the liquid lens 2 in the fixed direction, and the reliability and the stability of the camera module provided by the embodiment of the application are ensured.

Specifically, the embodiment of the present application will be described by way of the following two examples of the rolling connection between the rolling member 112 and the housing 3.
In one example, as shown in fig. 2, 7 and 9, a rolling groove 31 is provided at an end of the housing 3 (e.g., an upper end of the housing 3) remote from the liquid lens 2, and a rolling ball 112 is connected to the rotation member 111, wherein at least a portion of the rolling ball 112 is located within the rolling groove 31. In this manner, when the driving unit drives the rotation member 111 to rotate, the rolling ball 112 rolls in the rolling groove 31.
In another example, a slide rail is disposed at an upper end of the housing 3, the liquid lens 2 is close to a lower end of the housing 3, and a roller is connected to the rotating member 111, wherein the roller is disposed on the slide rail. Thus, when the driving unit drives the rotating member 111 to rotate, the roller rolls along the sliding rail.
Illustratively, the sliding member 113 may be a sliding block, the sliding block may be spherical or other shapes convenient for sliding, and a sliding slot 32 adapted to the sliding block may be provided on the housing 3. Wherein at least part of the slider is located within the chute 32. Thus, the rotation piece 111 can realize the sliding connection between the rotation piece 111 and the housing 3 by the cooperation between the slider and the slide groove 32.
Specifically, in one example, as shown in fig. 3, 4 and 8, a slide groove 32 is provided at the upper end of the housing 3, the liquid lens 2 is near the lower end of the housing 3, and a slider 113 is connected to the rotation member 111 (see fig. 4). Wherein at least part of the sliding member 113 is located in the sliding groove 32, and when the driving unit drives the rotating member 111 to rotate, the sliding member 113 can slide along the sliding groove 32, so that sliding connection between the rotating member 111 and the housing 3 is realized.
In the above examples, the limit function of the rotation member 111 during rotation may be achieved by the engagement between the rolling ball 112 and the rolling groove 31, or the engagement between the roller and the slide rail, or the engagement between the slide block and the slide groove 32, so as to ensure the stability of the rotation member 111 during rotation, for example, the rotation member 111 may rotate around a fixed center.
It will be appreciated that in the above examples, the rolling member 112 (or the sliding member 113) may be coupled to the inner sidewall of the rotating member 111 by a coupling member, or coupled to one end (e.g., a lower end) of the rotating member 111.
It will be appreciated that, in order to further secure the stability of the rotating member 111 during rotation, at least two of the above-described rolling grooves 31 (or sliding rails, or sliding grooves 32) are provided, and that these rolling grooves 31 (or sliding rails, or sliding grooves 32) may be uniformly disposed along the circumference. Specifically, referring to fig. 2, two rolling grooves 31 are uniformly provided on the circular tube-shaped housing 3.
It should be noted that, by providing rolling grooves 31 (or sliding rails, or sliding grooves 32) with different lengths, different maximum extrusion forces of the extrusion 12 on the liquid lens 2 can be achieved. The rolling grooves 31 (or sliding rails, or sliding grooves 32) with different lengths are formed, the rotating piece 111 can rotate at different angles, and then, the rotating piece 111 drives the extrusion piece 12 to extrude the liquid lens 2 through the connecting rod 13 to different degrees (namely, extrusion forces which can be applied to the liquid lens 2 by the extrusion piece 12 are different, or the liquid lens 2 deforms to different degrees), so that the sliding grooves 31 (or sliding rails, or sliding grooves 32) with different lengths can be formed for different liquid lenses 2, and further, extrusion forces which can be accepted by the liquid lens 2 are controlled in a controllable range, and the service life of the liquid lens 2 can be prolonged under the condition of meeting shooting requirements.
It should be noted that, for the specific connection structure between the extrusion 12 and the inner wall of the housing 3, reference may also be made to the sliding connection manner or the rolling connection manner between the rotating member 111 and the housing 3, so that the description thereof will not be repeated here.
