The transmission means commonly used in the prior art may be applied to the second transmission mechanism, such as one or more of gear engagement, friction transmission, belt transmission and chain transmission. It will be appreciated that when only one of the above described transmission schemes is employed, the driving of the driven member 323 by the driving member 322 may be accomplished by only one stage of transmission. The primary transmission structure is simple, has high reliability and occupies less space inside the housing 10. When two or more of the above-described transmission modes are adopted, the transmission cooperation of the two or more is two-stage or multi-stage transmission. The two-stage or multi-stage transmission can realize a larger transmission ratio adjustment, so that the rotation control of the camera 20 by the second driving motor 321 is more accurate. In this embodiment, the driving member 322 and the driven member 323 adopt gear transmission, that is, the rotating motor drives the gear output through the output shaft, and the gear is meshed with the gear arranged on the rotating portion 35, so as to drive the rotating portion 35 by the second driving motor 321.

when the driving assembly 30 is in the initial state (refer to fig. 1), the rotating portion 35 and the camera 20 are both accommodated in the housing 10. When the driving assembly 30 is started, the first driving motor 311 drives the sliding block 313 to move along the three directions 001 through the first transmission mechanism, the sliding block 313 drives the connecting seat 33 to move towards the outside of the housing 10 along the third direction 001 synchronously, and then the rotating portion 35 is driven to carry the camera 20 to move towards the outside of the housing 10 together. When the slider 313 moves to the maximum displacement, the camera 20 is fully extended out of the housing 10 (refer to fig. 3). The shooting direction of the camera 20 at this time coincides with the lens orientation when the camera 20 is housed in the housing 10. It is understood that when the mobile terminal includes a display screen, if the lens of the camera 20 accommodated in the housing 10 is directed to face the display screen, the camera 20 shows a front camera function after being extended out of the housing 10. If the lens of the camera 20 accommodated in the housing 10 faces away from the display screen, the camera 20 extends out of the housing 10 to perform a rear camera function. The camera 20 exhibiting the front camera function may drive the camera 20 to rotate by a second driving motor 321 in the driving assembly 30 if it is required to photograph toward the rear of the mobile terminal, or the camera 20 exhibiting the rear camera function may drive the camera 20 to rotate by an angle of 180 degrees if it is required to photograph toward the front of the mobile terminal (refer to fig. 4).

in practical implementation, the fixing bracket 21 may be set to be symmetrical in front and back, and the user may change the initial lens orientation of the camera 20 in front and back according to his or her needs. For example, when the user uses the rear camera 20 function more often, the camera 20 may be adjusted to be photographed right behind the mobile terminal by rotating the driving part 32, and then the camera 20 may be retracted. At this time, the lens of the camera 20 when it is accommodated in the housing 10 faces away from the display screen, and when the camera 20 is pushed out again, the user can directly use the camera 20 in the rear camera function to perform shooting without performing the rotation function. On the contrary, if the user frequently uses the self-timer, the camera 20 can be adjusted to be right opposite to the front of the mobile terminal for shooting by the rotary driving part 32, and then the camera 20 can be retracted. When the camera 20 is pushed out again, the lens of the camera 20 faces the display screen, and the self-photographing function can be completed quickly. In this case, the second position may be the position shown in fig. 3 or 4, that is, a position protruding out of the housing 10 and rotated by 0 ° or 180 ° with respect to the housing 10 (with reference to 0 ° with the camera 20 facing the display screen).

it can be understood that after the driving assembly 30 is equipped, the mobile terminal can simultaneously save a front camera and a rear camera, and only the driving assembly 30 can meet two shooting requirements. The mobile terminal saves cost, obtains larger internal space, is beneficial to arrangement of other components, and reduces the appearance volume.

in addition to switching the camera head 20 between the rear camera function and the front camera function, the driving assembly 30 can also be used to realize the camera head 20 to rotate by other fixed angles and different angles, such as ± 90 ° or random angles following the face of a person (see fig. 5 or fig. 6).

the detecting component 50 is used for detecting data representing the position state of the camera 20, wherein the position state includes a moving position and/or a rotating angle, wherein the moving position refers to a position that can move in a linear direction, such as a first position, a second position or any position between the first position and the second position. As an embodiment, the detecting assembly 50 includes at least one magnetic field sensor and at least one magnet, the at least one magnet is directly or indirectly fixed on the camera 20, the at least one magnetic field sensor is fixed and contained in the housing 10, the magnetic field sensor is a sensor made according to a hall effect, and can be used for detecting a magnetic field strength, and during a process that the at least one magnet moves along with the camera 20, the mobile terminal can represent a position state of the camera 20 according to the magnetic field strength detected by the magnetic field sensor.

In the present embodiment, referring to fig. 2 and fig. 3, the detecting assembly 50 includes a first magnetic field sensor 51, a first magnet 521 and a second magnet 522, that is, 1 magnetic field sensor and 2 magnets, the camera 20 is fixed on the fixing bracket 21, the bottom middle portion of the fixing bracket 21 is fixedly connected to the rotating portion 35, the fixing bracket 21 is provided with fixing grooves 23 on two sides of the rotating portion 35, the first magnet 521 and the second magnet 522 are respectively fixed in the corresponding fixing grooves 23, the first magnet 521 and the second magnet 522 are, for example, magnets, and the first magnetic field sensor 51 is disposed on the circuit board 60 in the housing 10. When the camera 20 moves and rotates, the first magnetic field sensor 51 may generate corresponding detection data according to the magnetic field strength of the first magnet 521 and the second magnet 522 at the first magnetic field sensor 51, and when the positions of the first magnet 521 and the second magnet 522 are changed, the detection data of the first magnetic field sensor 51 may also be changed accordingly, so that the position state of the camera 20 may be monitored.

In practical implementation, as shown in fig. 7, when the rotation angle of the camera 20 is 0 °, the first magnet 521 is aligned with the first magnetic field sensor 51 and the first magnetic pole faces the first magnetic field sensor 51, and when the rotation angle of the camera 20 is 180 °, the second magnet 522 is aligned with the first magnetic field sensor 51 and the second magnetic pole faces the first magnetic field sensor 51, the first magnetic pole and the second magnetic pole are magnetic poles in different directions, that is, when the first magnetic pole is S-pole (south pole), the second magnetic pole is N-pole (north pole), and conversely, when the first magnetic pole is N-pole, the second magnetic pole is S-pole, so that the rotation angle and the direction of the camera 20 can be distinguished according to the detection data of the first magnetic field sensor 51, and accurate position control of the camera 20 is realized. It can be understood that the detection accuracy can be improved by reasonably configuring the number and positions of the magnetic field sensors and the magnets, and when the configurations shown in fig. 2 and 7 are adopted, the cost of the configuration can be reduced while the detection accuracy is ensured.

fig. 8 is a schematic diagram illustrating connection of the magnetic field sensor and the main control chip according to the first embodiment. As shown in fig. 8, the first magnetic field sensor 51 is a packaged chip manufactured according to the hall effect, and is connected to the main control chip 70 through an I2C bus, so that the detected data can be sent to the main control chip 70 through an I2C bus, where SCL \ SDA is a signal line of an I2C bus, SDA is a bidirectional data line, and SCL is a clock line SCL, when SCL is high, SDA jumps from high level to low level to start data transmission, when SCL is high, SDA jumps from low level to high level to end data transmission, the main control chip 70 sends a signal to the first magnetic field sensor 51 and waits for the first magnetic field sensor 51 to send an acknowledgement signal, after the main control chip 70 receives the acknowledgement signal, the main control chip 70 makes a determination on whether to continue to transmit the signal according to an actual situation, and if the acknowledgement signal is not received, it is determined that the first magnetic field sensor 51 has a fault. The other interfaces in fig. 8 are connected by a general connection, which is known to those skilled in the art and will not be described herein.

the main control chip 70 is further connected to the first driving motor 311 and the second driving motor 321 in the driving assembly 30 directly or indirectly, and after receiving the inspection data of the first magnetic field sensor 51 through the I2C bus, the main control chip 70 determines whether the current position state of the camera 20 matches the target control position according to the detection data, and further sends a corresponding control signal to the first driving motor 311 or the second driving motor 321, so as to drive the camera 20 to the target control position.

It can be understood, when the first driving motor 311 of direct control, the second driving motor 321 carries out the rotation of certain angle and drives camera 20, because the precision, reasons such as external force, make first driving motor 311 very easily, second driving motor 321 produces drive angle, the deviation of distance, and then probably lead to camera 20 can't withdraw in the casing 10 or can't accurately aim at the problem of shooing the target, and after using the inspection subassembly of this application, can be according to the accurate control of detected data and revise first driving motor 311, the drive angle of second driving motor 321, the distance, thereby realize corresponding function smoothly, fine reinforcing user experience, stop the phenomenon of breaking down in the operation process, promote product intellectuality and science and technology and feel.

In actual implementation, when controlling the camera 20 to rotate to the second position, the preset angle value can be superimposed on the calculated angle for control, so as to ensure that the camera 20 is accurately stopped at the second position, and the camera 20 can be smoothly pulled back into the housing 10.

Third embodiment fig. 14 is a flowchart illustrating a control method of a mobile terminal according to a third embodiment. As shown in fig. 14, the method for controlling a mobile terminal according to this embodiment includes:

step 110, when a control signal of the camera is received, acquiring a target control position of the camera;

Step 120, judging whether the position state of the camera accords with the target control position according to the detection data of the detection assembly, wherein the position state comprises a moving position and/or a rotating angle;

And step 130, driving the camera according to the judgment result.

In step 110, the control signal of the camera 20 is triggered by a user operating on the mobile terminal, for example, performing a touch operation or pressing a physical key on the display screen, and in order to implement control of different functions of the camera 20, the control signals may be of various types, including starting the camera, closing the camera, rotating the camera, shooting, and recognizing shooting, where the shooting is performed at a current angle, and the recognizing shooting is performed such that the camera 20 is just shooting a shooting target. The mobile terminal generates different types of control signals according to the triggering operation of the camera 20 on the user, wherein when the camera 20 is in the first position shown in fig. 1, the mobile terminal generates a control signal for starting the camera 20, and when the camera 20 is in the second position shown in fig. 3 and 4 or any rotation angle shown in fig. 5 and 6, the mobile terminal can generate control signals for closing the camera, rotating the camera, shooting and recognizing shooting, which is specifically determined according to the operation of the user.

the different types of control signals correspond to different target control positions, when the control signals are signals for starting the camera, the second position is obtained as the target control position, when the control signals are signals for closing the camera, the first position is obtained as the target control position, when the control signals are rotation signals, the preset rotation angle corresponding to the control signals is obtained as the target control position, for example, 180 degrees, when the control signals are shooting signals, the current angle is obtained as the target control position, and when the control signals are recognition shooting, the angle enabling the camera 20 to be over against the shooting target is obtained as the target control position.

When the detecting component 50 is used to detect the magnetic field variation generated by the at least one magnet moving with the camera 20, the step 120 determines whether the position state of the camera matches the target control position according to the detection data of the detecting component, including:

Acquiring the magnetic field intensity detected by the detection assembly and a preset magnetic field intensity corresponding to the target control position;

Comparing the magnetic field intensity with a preset magnetic field intensity;

if the comparison is consistent, the position state of the camera is consistent with the target control position;

And if the comparison is inconsistent, the position state of the camera does not accord with the target control position.

Alternatively, when the detecting component 50 is used to detect the magnetic field variation generated by the at least one magnet moving with the camera 20, the step 120 of determining whether the position state of the camera matches the target control position according to the detection data of the detecting component includes:

Acquiring the position state of the camera according to the magnetic field intensity detected by the detection assembly;

Comparing the position state of the camera with a target control position;

If the comparison is consistent, the position state of the camera is consistent with the target control position;

and if the comparison is inconsistent, the position state of the camera does not accord with the target control position.

through the two manners, the mobile terminal can determine whether the camera 20 is currently located at the target control position, and then execute corresponding control operation.

In step 130, driving the camera according to the determination result, including:

If the position state of the camera does not accord with the target control position, determining a driving direction according to the position state of the camera and the target control position;

and controlling a driving component for driving the camera to drive the camera in the driving direction, and returning to the step of judging whether the position state of the camera conforms to the target control position according to the detection data of the detection component.

if the position state of the camera 20 does not match the target control position, the camera 20 is continuously driven until the camera 20 reaches the target control position. Specifically, the driving direction is determined according to the position state of the camera 20 and the target control position, for example, when the current position state of the camera 20 is the first position and the target control position is the second position, the driving direction is the third direction 001, when the current position state of the camera 20 is the second position and the target control position is the first position, the driving direction is the fourth direction 002, and when the current position state of the camera 20 is a rotation angle and the target control position is the second position, the driving direction is counterclockwise rotation or clockwise rotation. Then, the driving assembly 30 for driving the camera 20 is controlled to drive the camera 20 in a corresponding driving direction, for example, when the driving direction is the third direction 001 or the fourth direction 002, the first driving motor 311 is controlled to rotate in the corresponding direction, and when the driving direction is counterclockwise rotation or clockwise rotation, the second driving motor 321 is controlled to rotate in the corresponding direction, so that the camera 20 moves towards the target control position. In the process of driving the camera 20, whether the position state of the camera 20 is consistent with the target control position or not is judged in real time, and if not, the steps are continuously executed to enable the camera 20 to gradually approach the target control position. In actual implementation, the driving stroke of the driving assembly 30 may be calculated according to the driving direction, and when the driving assembly 30 reaches the driving stroke, the position state of the camera 20 is determined whether to match the target control position, and if not, the above steps are continuously executed to gradually approach the camera 20 to the target control position.

When the positional state of the camera 20 coincides with the target control position, the driving assembly 30 for driving the camera 20 is controlled to stop driving the camera 20. At this time, the camera 20 is precisely driven to the target control position, and since the driving group is controlled to drive the camera 20 according to the detection data of the detection assembly 50, the deviation of the driving angle and distance generated by the first driving motor 311 and the second driving motor 321 due to precision, external force and the like can be avoided, and the problem that the camera 20 cannot be retracted into the housing 10 or cannot be accurately aligned with the shooting target can be further solved.

Fourth embodiment

fig. 15 is a flowchart illustrating a control method of a mobile terminal according to a fourth embodiment. As shown in fig. 15, when the target control position is the first position, the method for controlling the mobile terminal includes:

step 210, acquiring a first position as a target control position;

Step 220, judging whether the position state of the camera is consistent with the first position; if not, go to step 230; otherwise, go to step 270;

step 230, acquiring the position state of the camera, and if the position state of the camera is a rotation angle, executing step 240; if the position status of the camera is the second position, step 250;

Step 240, taking the direction of rotating the camera from the rotation angle to the second position as the driving direction, and executing step 260;

Step 250, taking the direction of moving the camera from the second position to the first position as the driving direction, and executing step 260;

step 260, controlling a driving assembly for driving the camera to drive the camera in a driving direction, and executing step 220;

and step 270, controlling a driving component for driving the camera to stop driving the camera.

wherein, when the control signal is to close the camera, the first position is obtained as the target control position to recover the camera 20. And driving the camera 20 to recover in different routes according to the current position state of the camera 20.

When the position state of the camera 20 is the second position, please refer to fig. 3 or fig. 4, a direction that can move the camera 20 from the second position to the first position is taken as a driving direction, that is, a fourth direction 002 is taken as a driving direction, then, the first driving motor 311 is controlled to drive the lead screw 312 to pull the slider 313 back to the initial position along the fourth direction 002, and further, the camera 20 fixed on the rotating portion 35 is pulled back to the first position through the connecting seat 33, in this process, the second driving motor 321, the driving member 322 and the driven member 323 do not work, and the camera 20 is recovered into the housing 10 with the current shooting angle maintained. In the working process of the first driving motor 311, the first magnetic field sensor 51 detects the magnetic field strength, compares the detected magnetic field strength with the preset magnetic field strength corresponding to the first position, and when the detected magnetic field strength is the same as the preset magnetic field strength corresponding to the first position, the first driving motor 311 is controlled to stop working, and the camera 20 is driven to the first position and accommodated in the housing 10. To this end, the control process of recovering the camera 20 from the second position into the housing 10 is completed. It will be appreciated that the control process for pushing the camera head 20 out of the first position to the second position is similar, except that the output direction of the first drive motor 311 is reversed.

Referring to fig. 5 and 6, when the position state of the camera 20 is the first rotation position, a direction in which the camera 20 can be rotated from the rotation angle to the second position is first used as the driving direction, when the second position is the position shown in fig. 3, the clockwise rotation is used as the driving direction, and when the second position is the position shown in fig. 4, the counterclockwise rotation is used as the driving direction. Then, the second driving motor 321 is controlled to drive the driving member 322 to rotate, and further the driven member 323 drives the rotating portion 35 to rotate in the corresponding direction, so as to rotate the camera 20 fixed on the rotating portion 35 to the second position, in this process, the first driving motor 311, the lead screw 312, and the slider 313 do not operate, and the camera 20 does not perform linear movement. In the working process of the second driving motor 321, the magnetic field intensity is detected through the first magnetic field sensor 51, the detected magnetic field intensity is compared with the preset magnetic field intensity corresponding to the second position, when the detected magnetic field intensity is the same as the preset magnetic field intensity corresponding to the second position, the second driving motor 321 is controlled to stop working, and the camera 20 is driven to the second position. After the camera 20 is driven to the second position, the position state of the camera 20 is the second position and still does not match the first position, and at this time, the camera recovery process corresponding to fig. 3 or fig. 4 is executed, that is, the first driving motor 311 is controlled to drive the screw 312 to pull the slider 313 back to the initial position along the fourth direction 002, and then the camera 20 fixed on the rotating portion 35 is pulled back to the first position through the connecting seat 33, when the detected magnetic field strength is the same as the preset magnetic field strength corresponding to the first position, the first driving motor 311 is controlled to stop working, and the camera 20 is driven to the first position and is accommodated in the housing 10. At this point, the control process of recovering the camera 20 into the housing 10 from a certain rotation angle is completed. It can be understood that, in contrast to the control process of driving the camera 20 to a certain rotation angle from the first position, the camera 20 is started to drive the camera 20 to the second position, and then the camera 20 is driven to rotate to a certain angle.

In an embodiment, when the limiting structure 80 shown in the second embodiment is disposed in the mobile terminal, the step 260 of controlling the driving assembly for driving the camera to drive the camera in the driving direction may include:

If the driving direction is a direction for rotating the camera from a rotation angle to a second position, calculating a first rotation angle according to the rotation angle, the driving direction and a corresponding preset rotation angle;

superposing a preset angle value on the first rotation angle to obtain a second rotation angle;

and controlling a driving assembly for driving the camera to drive the camera in the driving direction according to the second rotation angle.

the first rotation angle is a rotation angle at which the camera 20 just rotates to the second position, the preset angle value is, for example, 5 °, and the two are overlapped to obtain the second rotation angle, so that when the camera 20 rotates to the second position, the motor in the rotation driving portion 32 continues to drive, and the camera 20 is enabled to accurately stop at the second position.

The embodiment can realize that the camera 20 is directly recovered from the second position or directly recovered from a rotation angle, and the user only needs to click to close the camera 20 to realize the automatic recovery of the camera 20, and the operation is simple.

fifth embodiment

fig. 16 is a flowchart illustrating a control method of a mobile terminal according to a fifth embodiment. As shown in fig. 16, when the control signal of the camera is the recognition photographing signal, the control method of the mobile terminal includes:

step 310, when the control signal of the camera is the recognition shooting signal, recognizing the shooting target through the camera;

step 320, taking the angle of the camera facing the shooting target as a target control position of the camera according to the recognition result;

step 330, judging whether the position state of the camera accords with the target control position according to the detection data of the detection assembly;

And step 340, driving the camera according to the judgment result.

The user can select the shooting target by clicking the scene in the view-finding frame so as to trigger and identify the shooting signal. Or triggering and identifying the shooting signal through preset operation, and identifying and selecting the shooting target in the view-finding frame according to preset priority through program control built in the mobile terminal. In general, the recognized shooting targets may be marked with frame lines in the finder frame.

the mobile terminal determines a target control position according to the relative position between the shooting target and the current shooting direction of the camera 20, and drives the camera 20 to rotate according to the target control position to obtain the shooting angle facing the shooting target, and the control process of step 330 and step 340 please refer to the related description of the embodiment of fig. 14, which is not repeated herein.

The embodiment is convenient for users to obtain a better shooting angle without adjusting the shooting posture. In the daily use process, due to the position relation between the shooting target and the user, the user can often adopt an unconventional shooting posture to obtain a better framing effect. Or, when the user is in a prone position, a sitting position, or the like, and is not convenient to move the body to adjust the shooting posture, a certain bad experience is also caused to shooting. Further, the action of pressing the shutter by the user in the case of an abnormal shooting posture is also laborious, which is likely to cause shaking of the mobile terminal and affect the imaging quality. According to the mobile terminal control method, the shooting target is identified, and the rotation angle of the camera 20 is adjusted through the driving assembly 30, so that the effect of directly facing the shooting target is achieved, better imaging quality can be obtained, and shooting experience of a user is improved.

when the shooting target is a moving target, step 320 uses the angle at which the camera is facing the shooting target as the target control position of the camera according to the recognition result, including:

If the shooting target is a moving target, calculating the angle of the camera facing the shooting target in real time according to the recognition result;

And updating the target control position of the camera according to the calculation result.

specifically, after the mobile terminal completes the recognition of the photographic target, if the photographic target keeps moving relative to the mobile terminal, the angle of the photographic target relative to the camera 20 is always in a changed state. In order to obtain a better shooting effect, the mobile terminal may drive the camera 20 to rotate through the second driving motor 321, so as to maintain the tracking alignment state of the camera 20 on the moving object. As can be appreciated, it is difficult for the mobile terminal to obtain a high-quality imaging effect for a moving photographic target. On one hand, the moving shooting target is relatively difficult to focus, and on the other hand, the shooting angle of the moving shooting target is difficult to obtain. Users often move mobile terminals to capture moving targets, and it is more difficult for the moving mobile terminals to achieve accurate focusing on the targets, thereby affecting the quality of the shooting. The mobile terminal control method of the embodiment can solve the problem of the shooting angle of the shooting target by rotating the camera 20 to keep tracking the moving shooting target. Meanwhile, the mobile terminal can keep a stable state, and a better focusing effect is obtained.

an embodiment, after the mobile terminal identifies the shooting target through the camera 20, further includes:

and if the shooting target is recognized to be the face, controlling the shooting mode to be switched to the beauty mode.

specifically, if the mobile terminal recognizes that the shooting target is a human face through the camera 20, the mobile terminal automatically switches the current shooting mode to the beauty mode. The front camera 20 of the mobile terminal is usually used for self-timer shooting, so that the front camera 20 is automatically switched to the beauty mode when being turned on. The user can obtain better self-timer effect through the beauty mode.
