In one example, the driving subunit may include: a rectifying and filtering circuit connected to the power module, a Micro Controller Unit (MCU) circuit and an Insulated Gate Bipolar Transistor (IGBT) driving circuit for adjusting the driving current, and a sampling circuit connected to the second magnet. The above structure of the second magnet and the driving subunit is only for clearly explaining the structure of the electromagnetic driving unit in the embodiment of the present invention, and the embodiment of the present invention is not limited thereto.
It should be noted that, as illustrated in the examples shown in fig. 3 and fig. 4, the first magnet may be embedded in the movable frame, and the second magnet may be embedded in the fixed frame, so that when the second magnet drives the first magnet to move, the structure of the first magnet or the second magnet does not hinder the movement of the movable frame.
It should be noted that, for the plurality of electromagnetic driving units, one driving subunit may be respectively provided for each electromagnetic driving unit, so as to individually drive the plurality of second magnets in the electromagnetic driving unit; one driving subunit may be provided for the plurality of electromagnetic driving units, and the driving subunits respectively drive the second magnets in the plurality of electromagnetic driving units, which is not limited in this embodiment of the present invention. The driving subunit may be independently disposed, or may be integrated into a corresponding module of the terminal, for example, a power module or a processor, which is not limited in this embodiment of the present invention.
In the embodiment of the present invention, the plurality of electromagnetic driving units and the plurality of magnetic units are arranged correspondingly, that is, an electromagnetic driving unit is correspondingly arranged at a position where each magnetic unit is indicated, and the electromagnetic driving unit is used for driving the magnetic unit to move in the first direction. In order to realize that the second magnet drives the first magnet to move towards the first direction, the movable mechanism can be driven to rotate towards the second direction, the second magnet in the electromagnetic driving unit can be arranged at the non-axial position of the first magnet in the corresponding magnetic unit, namely, the second magnet and the first magnet can be opposite to each other in any radial direction of the first magnet, and further, when the second magnet generates magnetism, the first magnet can be driven to radially generate relative movement relative to the second magnet. When the electromagnetic driving unit has a plurality of second magnets, the plurality of second magnets can be distributed on different radial corresponding directions of the first magnet, so as to respectively drive the first magnet to generate relative motion in the corresponding radial direction from different positions. The actual moving direction of the first magnet, i.e. the first direction in the embodiment of the present invention, should be a direction obtained by vector-synthesizing the directions in which the plurality of second magnets drive the first magnet to generate the relative movement.
In an alternative embodiment, the electromagnetic driving unit 1062 includes a plurality of second magnets 10624, and the plurality of second magnets 10624 are symmetrically disposed with respect to the first magnet 1042.
In an example, the electromagnetic driving unit includes four second magnets, the four second magnets are distributed at 90 ° with respect to each other, fig. 7 is a schematic position diagram (one) of the first magnet and the second magnet provided according to the embodiment of the present invention, fig. 8 is a schematic position diagram (two) of the first magnet and the second magnet provided according to the embodiment of the present invention, as shown in fig. 7 and 8, the electromagnetic driving unit includes four second magnets, which are respectively the second magnet 21, the second magnet 22, the second magnet 23, and the second magnet 24, the second magnet 21, the second magnet 22, the second magnet 23, and the second magnet 24 are sequentially disposed at four orientations, i.e., upper, left, lower, and right, of the first magnet 20, and the four second magnets are rotationally symmetric with respect to the first magnet.
As shown in fig. 7, when the first driving signal indicates that the first magnet 20 needs to move upward, the second magnet 21 and the second magnet 23 are controlled to be in a closed circuit, and the second magnet 22 and the second magnet 24 are kept in an open circuit, so that the second magnet 21 generates magnetic force attracting to the first magnet 20 and magnetic force repelling to the first magnet 20 and the second magnet 23. In this case, the second magnet 21 can attract the first magnet 20, and the second magnet 23 can repel the first magnet 20, so that the first magnet 20 moves upward under the combined action of the second magnet 21 and the second magnet 23. Similarly, when the first driving signal indicates that the first magnet 20 needs to move leftward, the second magnet 21 and the second magnet 23 are controlled to remain open, and the second magnet 22 and the second magnet 24 form a path, so that the second magnet 22 generates attractive magnetic force with the first magnet 20 and repulsive magnetic force between the second magnet 24 and the first magnet 20. In this case, the second magnet 22 can attract the first magnet 20, and the second magnet 24 can repel the first magnet 20, so that the first magnet 20 moves leftwards under the combined action of the second magnet 22 and the second magnet 24.
It should be noted that, in the above example, the cooperative movement of the two second magnets can significantly improve the driving force of the second magnets to the first magnet, or the movement of the first magnet can be controlled by only one second magnet, for example, the second magnet 21 is separately powered to generate attractive magnetism with the first magnet 20, so as to move the first magnet upwards.
In the above example, in the case that the first driving signal indicates that the first magnet 20 moves to the upper left direction, the second magnet 21 and the second magnet 22 are controlled to form a passage and respectively generate magnetism attracting the first magnet 20; the first magnet 20 can move upward and leftward according to a vector composition under the condition of being respectively subjected to upward and leftward attractive forces. In the above situation, the second magnet 23 and the second magnet 24 can generate the repulsive magnetic force with the first magnet 20, respectively, to improve the motion strength. Therefore, the first magnet can move to different directions through the combined action of the plurality of second magnets. It should be noted that, in the above example, the number of the second magnets is only to illustrate the relative position relationship and the control manner of the second magnets in the electromagnetic driving unit and the first magnets in the magnetic unit more clearly, and the number of the second magnets is not limited in the embodiment of the present invention, and a person skilled in the art may use more second magnets, for example, 8 second magnets distributed at 45 ° to each other, to implement more precise control of the movement direction of the first magnets, or use fewer second magnets, for example, 3 second magnets distributed at 120 ° to each other, to implement control of hardware cost and structural space according to actual working conditions.
In another example, the electromagnetic driving unit may include two second magnets disposed at 180 ° from each other, which are respectively disposed in an upper and lower direction, or a left and right direction of the first magnet. Therefore, the electromagnetic driving unit can drive the first magnet to move in the opposite direction of the second magnet only through the two second magnets. In the above example, two magnetic units are disposed at a certain position of the movable mechanism, and correspond to a set of the electromagnetic driving units, respectively, wherein two second magnets in one set of the electromagnetic driving units are respectively located at the upper and lower positions of the first magnet in the corresponding magnetic unit, and two second magnets in the other set of the electromagnetic driving units are respectively located at the left and right positions of the first magnet in the corresponding magnetic unit; therefore, the two groups of electromagnetic driving units can respectively control the movement of the first magnets in the corresponding magnetic units in the corresponding directions, so that the movable mechanism can move in a matching way through the two magnetic units, and further can generate movement control in the up-down, left-right and other directions at the position. The electromagnetic driving units in this example are configured such that each group of electromagnetic driving units only needs to control the motion parameters in two directions, thereby effectively simplifying the calculation load of the driving subunit in determining the driving current.
The connection and disconnection of the second magnet in the electromagnetic driving unit and the power supply signal provided by the power supply module to the second magnet are realized by the driving subunit according to a first driving signal, and the first driving signal is generated in advance by the processor. The generation of the first driving signal is described below by way of an alternative embodiment:
in an optional embodiment, the processing unit 102 is configured to obtain shake information of the camera module, and generate a first driving signal according to the shake information; the shake information is used for indicating the shake state generated by the camera module.
In an example, the shake information may be obtained by detecting a shake state of the camera module or the terminal by a sensor mounted on the terminal itself, such as an angle sensor or a gyroscope. In another example, the shake information may also be obtained by acquiring a currently shot image through the camera module, and analyzing the image to determine a shake state of the camera module. In an optional embodiment, after acquiring the jitter information, the processing unit performs the following operations:
acquiring a plurality of jitter sub-information according to the jitter information; the plurality of jitter sub-information are used for indicating jitter components of the jitter information in different directions;
generating a first driving sub-signal according to the dithering sub-information, wherein the first driving sub-signal is used for indicating a rotation component opposite to the dithering component indicated by the dithering sub-information; the first drive signal is composed of a plurality of first drive sub-signals.
It should be noted that, for the shake information, the shake information may be decomposed into shake sub information in different directions, in an example, fig. 9 is a schematic diagram of shake coordinates of the image capturing module according to an embodiment of the present invention, and as shown in fig. 9, the directions may be directions of an X axis, a Y axis, and a Z axis in a three-dimensional coordinate system established with the image capturing module as a center, and the shake sub information indicates a deflection angle of the image capturing module occurring on the X axis, the Y axis, and the Z axis during the shake occurrence process, that is, a shake component in the embodiment of the present invention. By the above example, after determining the shake components of the camera module on the X axis, the Y axis, and the Z axis, the camera module is rotated in opposite phases on the X axis, the Y axis, and the Z axis relative to the shake components, so that the shake can be eliminated; therefore, a first driving sub-signal for instructing the image pickup module to perform corresponding rotation in the corresponding direction can be generated, and the rotation component instructed by the first driving sub-signal is the same as and opposite to the shake component in the direction. As shown in fig. 9, the first driving sub-signals corresponding to the X-axis, the Y-axis, and the Z-axis may respectively indicate that the camera module needs to rotate on the X-axis, the Y-axis, and the Z-axis by R1, R2, and R3.
After the processing unit generates the first driving signal comprising the plurality of first driving sub-signals, the first driving signal can be sent to each electromagnetic driving unit, so that each electromagnetic driving unit obtains the first driving sub-signal in the direction of the electromagnetic driving sub-unit, and drives the corresponding magnetic unit to move towards the first direction according to the rotation component indicated by the first driving sub-signal. Therefore, the magnetic unit can be driven to move towards the first direction through the electromagnetic driving unit, and the movable mechanism and the camera module are driven to rotate accordingly. As shown in fig. 9, four magnetic units, M1, M2, M3 and M4, are disposed in the movable mechanism; the magnetic units M1, M2, M3, and M4 are driven by the corresponding electromagnetic driving units to move in respective first directions, so as to drive the movable mechanism and the camera module to rotate R1, R2, and R3 in the X axis, Y axis, and Z axis, thereby counteracting the shake generated during the shooting process.
In an optional embodiment, for the above situation, the movable mechanism 104 is further provided with a first angle sensor 1044, and the first angle sensor 1044 is configured to acquire the angle of rotation of the movable mechanism 104 to generate angle information, and send the angle information to the processing unit 102, so as to instruct the processing unit 102 to generate the second driving signal according to the angle information.
It should be noted that the first angle sensor may be disposed on the movable mechanism, so as to detect an actual rotation angle of the movable mechanism, so as to generate angle information. The processing unit can determine whether the actual rotating angle of the movable mechanism reaches the required rotating angle or not according to the angle information, and the processing unit can generate a second driving signal according to the difference value between the angles when the actual rotating angle of the movable mechanism does not reach the required rotating angle so as to drive the movable mechanism to continue to rotate until the movable mechanism completely rotates to the required angle and can eliminate the shake of the camera module. To illustrate with the example shown in fig. 4, the first angle sensor may be disposed at the bottom of the movable frame.
It should be noted that, in the case that an elastic connection mechanism is provided in the fixing mechanism, such as a spring, the movable mechanism is also under the elastic action of the elastic connection mechanism during the movement process, that is, the movable mechanism is driven to rotate by the magnetic action of the second magnet under the first magnet on the one hand, and is restrained by the elastic connection mechanism on the other hand, so that the larger the movement amplitude of the movable mechanism is, the larger the restraining force of the elastic connection mechanism on the movable mechanism is, and the electromagnetic acting force of the second magnet on the first magnet and the traction force of the elastic connection mechanism are indicated to be balanced with each other.
According to the camera anti-shake device in the embodiment of the invention, the plurality of electromagnetic driving units in the fixed mechanism can generate magnetic action on the plurality of magnetic units in the movable mechanism according to the first driving signal, so that the magnetic units are driven to move towards the first direction; in the process of moving the magnetic units, the movable mechanism can be driven to move integrally together with the camera module arranged on the movable mechanism to the second direction, so that the shake of the camera module in the process of video shooting can be counteracted. Therefore, the camera shooting anti-shake device in the embodiment of the invention can solve the problem that shake cannot be effectively prevented in the video shooting process of the terminal in the related technology, so that when the terminal shoots a video, especially when a user moves to shoot the video, or the terminal is carried on an unmanned aerial vehicle holder to shoot and other multi-shake shooting scenes, a camera shooting module can effectively prevent shake, and further a stable video shooting effect is realized.
On the other hand, because the camera shooting anti-shake device in the embodiment of the invention is driven by electromagnetism, the camera shooting anti-shake device does not need to be provided with a motor and other equipment, and the occupied space of the camera shooting anti-shake device is obviously reduced compared with the related technology, so that the camera shooting anti-shake device in the embodiment of the invention can be installed in a terminal, especially in a mobile terminal with a more compact internal space.
