The camera module 100 and the electronic device 200 provided in the embodiment of the present application are described below with reference to fig. 1 to 12.
As shown in fig. 1, the camera module provided in the embodiment of the present application can be applied to an electronic device. The electronic device can be a mobile phone, a tablet computer, an intelligent bracelet and the like.
In this embodiment, the camera module includes: the liquid lens system 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 fig. 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, under the condition that the rotating structure 11 rotates, the second end of the connecting rod 13 moves in the direction of the optical axis of the liquid lens 2 in the shell 3, and presses the liquid lens 2 during the moving process to adjust the focal length of the liquid lens 2.
In the embodiment of the present application, the specific structural relationship between the liquid lens 2 and the housing 3 includes, but is not limited to, the following manners: the liquid lens 2 can be arranged in a cavity formed by the shell 3; alternatively, 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; alternatively, the liquid lens 2 is disposed at one end of the housing 3.
It can be understood 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 in the rotating process, and in the moving 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 in the reciprocating process, the liquid lens 2 can be extruded to deform (i.e. the focal length of the liquid lens 2 changes) through transmission. The deformation degree that the liquid lens 2 of extrusion produced is different for the difference of drive power size, and then, exerts different drive power through applying rotating-structure 11, changes the focus of above-mentioned camera module (different drive power corresponds the focus that liquid lens 2 is different promptly).
That is to say, when the camera module is used for photographing or shooting a 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 reciprocating motion process, and after the shape is changed, the focus position of the liquid lens 2 moves, so that the focusing of the camera can be realized.
Exemplarily, the rotating structure 11 may be directly connected with the housing 3 through a sliding structure or a rolling structure; alternatively, the rotary structure 11 is connected to the housing 3 via a mounting portion (e.g., a bracket) on which the rotary structure 11 can rotate. Rotating-structure 11 can also be connected with casing 3 through other connection structure, as long as can realize rotating-structure 11 and at the pivoted in-process, drive connecting rod 13 motion to the second end of connecting rod 13 can be in casing 3 along the optical axis direction of liquid lens 2 do reciprocating motion can, rotating-structure 11 and casing 3's concrete connection structure can be selected according to actual need, and this application embodiment does not limit to this.
It can be understood that the first end of the connecting rod 13 can be rotatably connected to the rotating structure 11, so that when the rotating structure 11 rotates, the angle of the included angle between the connecting rod 13 and the rotating structure 11 changes, 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 is close to or away from the liquid lens 2 along the optical axis direction of the liquid lens 2, and in the process that the second end of the connecting rod 13 is close to or away from the liquid lens 2, the connecting rod 13 presses the liquid lens 2 through transmission in the process of being close to the liquid lens 2, 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.
For example, as shown in fig. 1 and 2, the rotating structure 11 may be disposed at one end (e.g., upper end) of the housing 3, and the liquid lens 2 may be disposed at the other end of the housing 3 (e.g., inner wall of the housing 3 is close to lower end of the housing 3); a first end of the link 13 (e.g., an upper end of the link 13) is rotatably connected to the rotating structure 11, and a second end (e.g., a lower end of the link 13) is drivingly connected to the liquid lens 2. Therefore, when the rotating structure 11 rotates, the connecting rod 13 can be switched between a vertical state and an inclined state, and in the switching process, the connecting rod 13 extrudes the liquid lens 2 through transmission 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 tubular, 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 that this application embodiment provided, including casing, liquid camera lens, rotating-structure and connecting rod. The liquid lens sets up in above-mentioned casing, and revolution mechanic is connected with the casing, and the first end and the revolution mechanic of connecting rod are connected, and the second end is connected with the transmission of liquid lens, because receive drive power pivoted circumstances at revolution mechanic, the second end of connecting rod can be followed liquid lens's optical axis direction up reciprocating motion in the casing to at the focus of reciprocating motion in-process adjustment liquid lens. This application embodiment can drive the shift position of connecting rod second end through drive power control rotating structure, through shift position's difference, the connecting rod passes through the difference that transmission extrusion liquid camera lens produced deformation degree in the physical structure, and then realize zooming (being focus position's removal) of camera module, thus, the inside electrolyte of the liquid camera lens of this application embodiment, as long as optical index such as luminousness and refracting index satisfy the requirement can, can not influence the imaging quality because of the electric properties such as the conductivity of the inside electrolyte of liquid camera lens and circular telegram deformation, the selection scope of the inside electrolyte of liquid camera lens has been enlarged.
Optionally, in this embodiment of the 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 thin design of the camera module is taken into consideration, 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., to provide driving force to the rotating structure 11).
For example, the driving unit may be an electric driving unit, or a mechanical driving unit, or a manual driving unit, or other possible driving units, which is not limited in the embodiments of the present application, and the embodiments of the present application are only exemplified by the driving unit in an electric manner.
Optionally, in this application embodiment, above-mentioned camera module still includes the extruded article, and extruded article 12 sets up in the casing, and extruded article 12 is connected with the second end of connecting rod 13, and connecting rod 13 drives extruded article 12 and removes, and extruded article 12 extrudes liquid camera lens to the focus of adjustment liquid camera lens. That is, the second end of the connecting rod 13 can drive the extrusion component 12 to extrude the liquid lens 2 to change the focal length.
It is understood that an extrusion 12 may be located between the connecting rod 13 and the liquid lens 2, the extrusion 12 being used to extrude 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 piece 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 in the reciprocating process, the extrusion piece 12 can extrude the liquid lens 2 to deform. The difference of driving power size, the deformation degree that extruded article 121 extrusion liquid lens 2 produced is different, and then, changes the focus of above-mentioned camera module (the different focus that drives power corresponding liquid lens 2 of difference promptly).
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 will move.
Illustratively, the rotational connection between the second end of link 13 and extrusion 12 may be: the rotation connection in a hinge mode, or the rotation connection in a clamping mode, or other possible rotation connection modes, which are not limited in the embodiments of the present application.
Illustratively, as shown in fig. 2 and 3, the rotary 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, and a second end of the link 13 is rotatably connected to an upper end of the pressing member 12, a lower end of the pressing member 12 facing the liquid lens 2. Therefore, when the rotating structure 11 rotates, the connecting rod 13 can drive the extrusion part 12 to move upwards or downwards (namely, to be close to or far away from the liquid lens 2), in the downward movement process of the extrusion part 12, the extrusion part 12 is close to the liquid lens 2 and can be in contact with the liquid lens 2, along with the continuous rotation of the rotating structure 11, the extrusion part 12 can continue to extrude the liquid lens 2, and the focus of the liquid lens 2 can move.
Illustratively, and referring to fig. 1 and 2, as shown in fig. 4 and 5, the rotary structure 11 is provided on the housing 3, and the upper end of the pressing member 12 is rotatably connected to the rotary structure 11 by a link 13.
When the camera module provided by the embodiment of the application is used for shooting, when the driving unit drives the rotating structure 11 to rotate towards a first direction (for example, clockwise direction), the extrusion piece 12 can move downwards (namely, close to the liquid lens 2), when the driving unit rotates to the first state, referring to fig. 4, the connecting rod 13 is perpendicular to the extrusion piece 12 (namely, 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 maximum, the extrusion piece 12 can extrude the liquid lens 2 to the maximum extent, and the liquid lens 2 generates the maximum deformation in this state.
If the camera module needs to be zoomed, the focus 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 (for example, counterclockwise) opposite to the first direction, the extrusion piece 12 moves upwards (i.e., away from the liquid lens 2), when the rotating structure 11 drives the extrusion piece 12 to move upwards to the second state through the connecting rod 13, referring to fig. 5, the included angle between the connecting rod 13 and the extrusion piece 12 is an acute angle (i.e., the connecting rod 13 is in an inclined state, and the connecting rod 13 and the extrusion piece 12 are in a non-perpendicular relationship), and the distance between the extrusion piece 12 and the rotating structure 11 decreases. 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 the maximum pressing force of the pressing member 12 on the liquid lens 2 (i.e. the maximum deformation of the liquid lens 2) can be controlled by controlling the length of the connecting rod 13. Furthermore, on the premise of ensuring the normal zooming of the liquid lens 2, according to the difference of the maximum extrusion force that the different liquid lenses 2 can bear, the connecting rods 13 with different lengths can be arranged for the different liquid lenses 2, and then the extrusion force that the liquid lens 2 can bear is controlled within a controllable range, so that the service life of the liquid lens 2 can be prolonged under the condition of meeting the shooting requirement.
Illustratively, the number of the links 13 may be at least two, and the links 13 may be uniformly arranged (for example, uniformly arranged along the circumference), so that the driving force can be uniformly provided to the extrusion member 12 in the circumferential direction through the links 13, and the extrusion force can be uniformly applied to the liquid lens 2 in the circumferential direction through the extrusion member 12. Specifically, referring to fig. 2 and 6, there are two connecting rods 13, and the two connecting rods 13 are uniformly arranged along the circumference of the extrusion 12.
Illustratively, the above-described extrusion 12 may be ring-shaped, such as circular ring-shaped, or square ring-shaped; alternatively, the above-described pressing member 12 may include a plurality of pressing pieces, which may be uniformly arranged along the circumference. The liquid lens may protrude from the inner circle of the annular extrusion member during the movement of the extrusion member 12 described above.
Illustratively, the outline shape of the extrusion 12 may coincide with the outline 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 present embodiment, extrusion 12 is annular and extrusion 12 is slidably attached to the inner wall of housing 3.
Illustratively, the sliding connection between the extrusion 12 and the inner side wall of the housing 3 may include, but is not limited to, the following connections: the extrusion piece 12 is connected with the inner wall (i.e. inner side wall) of the shell 3 in a sliding way through a sliding groove, and the extrusion piece 12 is connected with the inner side wall of the shell 3 in a sliding way through a sliding rail.
Through several kinds of sliding connection modes, in the extrusion piece 12 slip in-process, extrusion piece 12 can move along the direction of sliding tray or slide rail to make extrusion piece 12 can extrude liquid lens 2 and produce different deformations in the motion process, realize the focusing to liquid lens 2.
Optionally, in this embodiment of the application, the camera module further includes a first limiting groove 4 and a boss 5 adapted to the first limiting groove 4.
Wherein, the sliding connection between the extrusion part 12 and the inner side wall of the shell 3 can be realized through the matching between the first limit groove 4 and the boss 5.
The present embodiment will explain the sliding connection between the pressing member 12 and the housing 3 by the following two examples.
In one example, as shown in fig. 10 and 11, the first limiting groove 4 may be provided on the inner wall of the housing 3, the first limiting groove 4 extends in the optical axis direction of the liquid lens, the boss 5 may be provided on the outer periphery of the pressing member 12, and the boss 5 may be caught in the first limiting groove 4, so that the boss 5 reciprocates (e.g., moves upward or downward) in the first limiting groove 4 as the pressing member 12 approaches or moves away from the 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 outer periphery of the extrusion member 12, the boss 5 is disposed on the inner wall of the housing 3, the boss extends in 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 reciprocates (e.g., moves upward or downward) in the first limiting groove 4 as the extrusion member 12 approaches or moves away from the liquid lens 2.
These two kinds of examples, through the cooperation between first spacing groove 4 and the boss 5, can be close to or keep away from liquid lens 2 at extruded piece 12 in-process, realize the limiting displacement to extruded piece 12, guarantee extruded piece 12 promptly and be close to or keep away from liquid lens 2 in the fixed direction, guaranteed the reliability and the stability of the camera module that this application embodiment provided.
It can be understood that, in order to further ensure the reliability and stability of the camera module provided in the embodiment of the present application, the number of the first limiting grooves 4 may be at least two, and the first limiting grooves 4 may be uniformly arranged (for example, uniformly arranged along the circumference). Specifically, referring to fig. 10, there are 4 first limiting grooves 4, and the 4 first limiting grooves 4 are uniformly arranged along the inner wall of the housing 3.
It is to be understood that, in the case where the above-mentioned pressing member 12 includes a plurality of pressing pieces, each of the pressing pieces is slidably connected to the above-mentioned housing 3, and a link 13 is connected to each of the pressing pieces.

In the embodiment of the present application, the driving unit may drive the rotating member 111 to rotate, and in the case that the rotating member 111 rotates, the second end of the connecting rod 13 moves in the optical axis direction of the liquid lens 2 in the housing 3, that is, the rotating member 111 drives the extrusion member 12 to approach or separate from the liquid lens 2 in the housing 3 through the connecting rod 13.
For example, the rotating component 111 may be a gear or other structural component capable of rotating under the driving force, and the embodiment of the present application is not limited thereto.
Illustratively, the rolling member 112 may be a rolling ball, and a rolling groove 31 adapted to the rolling ball may be provided on the housing 3, so that the rotating member 111 can realize a rolling connection between the rotating member 111 and the housing 3 by the cooperation between the rolling ball and the rolling groove 31.
The rolling element 112 may also be a roller, and a sliding rail adapted to the roller may be disposed on the housing 3, so that the rotating element 111 may realize a rolling connection between the rotating element 111 and the housing 3 through cooperation between the roller and the sliding rail.
Specifically, the present embodiment will explain the rolling connection manner between the rolling member 112 and the housing 3 by the following two examples.
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) away from the liquid lens 2, and a ball 112 is connected to the rotation member 111, wherein at least a portion of the ball 112 is located in the rolling groove 31. Thus, when the driving unit drives the rotation member 111 to rotate, the rolling balls 112 roll in the rolling grooves 31.
In another example, a slide rail is disposed at the upper end of the housing 3, the liquid lens 2 is adjacent to the 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.
For example, the sliding member 113 may be a sliding block, the sliding block may be spherical or other shapes that facilitate sliding, and a sliding groove 32 adapted to the sliding block may be provided on the housing 3. Wherein at least a portion of the slider is positioned within the chute 32. Thus, the rotating member 111 can realize the sliding connection between the rotating member 111 and the housing 3 by the cooperation between the slider and the sliding groove 32.
Specifically, in one example, as shown in fig. 3, 4, and 8, the slide groove 32 is provided at the upper end of the housing 3, the liquid lens 2 is close to the lower end of the housing 3, and the slider 113 is connected to the rotation member 111 (see fig. 4). Wherein at least a part of the sliding member 113 is located in the sliding slot 32, when the driving unit drives the rotating member 111 to rotate, the sliding member 113 can slide along the sliding slot 32, thereby achieving the sliding connection between the rotating member 111 and the housing 3.
In the above examples, the rotation element 111 can be limited during rotation by the cooperation between the rolling ball 112 and the rolling groove 31, or the cooperation between the roller and the sliding rail, or the cooperation between the sliding block and the sliding groove 32, so as to ensure the stability of the rotation element 111 during rotation, for example, the rotation element 111 can rotate around a fixed center.
It is understood that, in the above examples, the rolling member 112 (or the sliding member 113) may be connected to the inner sidewall of the rotating member 111 through a connecting member, or connected to one end (e.g., the lower end) of the rotating member 111.
It is understood that, in order to further ensure the stability of the rotating member 111 during the rotation process, the number of the rolling grooves 31 (or the sliding rails, or the sliding grooves 32) is at least two, and the rolling grooves 31 (or the sliding rails, or the sliding grooves 32) may be uniformly arranged along the circumference. Specifically, referring to fig. 2, two rolling grooves 31 are uniformly formed in 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 pressing forces of the pressing member 12 on the liquid lens 2 can be controlled. Different length's roll groove 31 (or slide rail, or spout 32), it can the pivoted angle different to rotate piece 111, and then, it is different that it drives the degree that extruded article 12 extrudes liquid camera lens 2 through connecting rod 13 to rotate piece 111 (the extruded article 12 can be applyed the extrusion force difference for liquid camera lens 2 promptly, or liquid camera lens 2 produces the degree of deformation different), therefore, equally, to different liquid camera lens 2, can set up the sliding tray 31 (or the slide rail of different length, or spout 32), and then, the extrusion force control that can accept liquid camera lens 2 is in controllable range, can be under the demand that satisfies the shooting, prolong liquid camera lens 2's life.
It should be noted that, the specific connection structure between the pressing member 12 and the inner wall of the housing 3 may refer to the sliding connection manner or the rolling connection manner between the rotating member 111 and the housing 3, and for avoiding repetition, the detailed description is omitted here.
