[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0054] On the one hand, as shown in Figures 1-3 this embodiment provides a mobile terminal, which includes: a battery module 1, a power supply circuit 2, a charging circuit 3, and at least one motor element 4.

[0055] The battery module 1 is electrically connected to at least one motor element 4 through the power supply circuit 2 and the charging circuit 3.

[0057] In the power consumption mode, the power supply circuit 2 is turned on, the charging circuit 3 is turned off, the battery module 1 supplies electrical energy to at least one motor element 4, and at least one motor element 4 outputs mechanical energy.

[0058] In the charging mode, the charging circuit 3 is turned on, the power supply circuit 2 is turned off, and at least one motor element 4 converts mechanical energy into electrical energy and inputs the electrical energy into the battery module 1.

[0059] The mobile terminal of this embodiment includes a battery module 1, a power supply circuit 2, a charging circuit 3, and at least one motor element 4. The battery module 1 is electrically connected to the motor element 4 through the power supply circuit 2 and the charging circuit 3. In the power consumption mode, the power supply circuit 2 is turned on, the charging circuit 3 is turned off, the battery module 1 supplies power to the motor element 4, and the motor element 4 converts electrical energy into mechanical energy to perform the target function of the mobile terminal. In the charging mode, the charging circuit 3 is turned on, the power supply circuit 2 is turned off, the motor element 4 converts mechanical energy into electrical energy to charge the battery module 1, thus different from the disadvantages of only being able to be charged by an external power source in the related art. It is possible to charge the battery module 1 by doing work on the motor element 4, improving the battery life of the mobile terminal.

[0060] In some possible implementation manners, the battery module 1 includes but is not limited to lithium batteries, nickel-metal hydride batteries, etc., and has controllable discharge and charging capabilities.

[0061] As shown in Figure 3 and Figure 4 in some embodiments, the mobile terminal includes a camera module 5, and at least one motor element 4 is located inside the camera module 5.

[0062] In the power-on mode, at least one motor element 4 is configured to utilize mechanical energy to implement the focusing function and / or anti-shake function of the camera module 5.

[0063] The camera module 5 is a key functional component in a mobile terminal for taking still pictures or short videos, enabling the mobile terminal to have richer multimedia functions. Auto Focus (AF) is an important function of the camera module 5. By adjusting the distance between the lens and the photosensitive element and the focal length of the camera module 5, the blurring and spotting phenomena of the picture can be eliminated, and the picture can be made clear and bright. The realization of the auto-focus function mainly depends on the internal motor element 4. Anti-shake, also known as OIS optical anti-shake, works on the principle that when the body vibrates, it controls the lens in the camera module 5 to float, compensating for a certain displacement of the body vibration, thereby preventing the optical path from shaking and achieving optical anti-shake. The realization of the anti-shake function also mainly depends on the internal motor element 4.

[0064] As the functional requirements of the camera module 5 continue to increase, the size and stacking space of the camera module 5 continue to increase, and the size, number of coil turns, moving part mass, etc. of the motor element 4 used in the camera module 5 all continue to increase. This enables the motor element 4 in the camera module 5 to have sufficient moving space and kinetic energy to participate in the electromagnetic conversion of mechanical energy and electrical energy, so that the motor element 4 in the camera module 5 can convert the electrical energy in the battery module 1 into mechanical energy in the power-on mode to implement the focusing function and / or anti-shake function of the camera module 5. In the charging mode, it can convert the mechanical energy of the moving part in the camera module 5 into electrical energy to charge the battery module 1, thereby improving the battery life of the mobile terminal.

[0065] In some embodiments, the mobile terminal includes a vibration generating module, and at least one motor element 4 is located within the vibration generating module; in the power-on mode, at least one motor element 4 is configured to utilize mechanical energy to implement the vibration function of the vibration generating module.

[0066] In the mobile terminal, the vibration generating module can provide a vibration feeling for the mobile terminal, which is used for message reminders, incoming call reminders, as well as button feedback, game vibration feedback, and so on. The vibration generating module can utilize the motor element 4 to achieve the conversion between electrical energy and mechanical energy, and can also achieve the conversion between mechanical energy and electrical energy.

[0067] Combined Figure 2 As shown, in some embodiments, the power supply circuit 2 includes a driving unit 21. The first input terminal 211 of the driving unit 21 is electrically connected to the battery module 1, and the first output terminal 212 of the driving unit 21 is electrically connected to at least one motor element 4.

[0068] Among them, the driving unit 21 can also be a motor driver, also known as a motor controller or an inverter, which is used to control the operation of the motor element 4. Its working principle is basically to convert the input DC electrical energy into controllable AC electrical energy to drive the motor to rotate. The main functions are as follows: power supply, input the current output by the battery module 1 into the motor element 4 to enable it to drive the motor element 4 to operate; signal reception, receive signal input from a control signal source, such as a main board, etc.; signal processing, process and convert the received signals to meet the working requirements of the motor element 4, such as speed, acceleration, etc.; feedback control, by measuring the output position signal, send the feedback signal back to the driving unit 21 to achieve closed-loop control and adjustment, so that the motor element 4 can achieve more precise movement.

[0069] The charging circuit 3 includes a rectifying unit 31 (rectifier) and a voltage conversion unit 32. The second input terminal 311 of the rectifying unit 31 is electrically connected to at least one motor element 4, the second output terminal 312 of the rectifying unit 31 is electrically connected to the third input terminal 321 of the voltage conversion unit 32, and the third output terminal 322 of the voltage conversion unit 32 is electrically connected to the battery module 1.

[0070] Among them, the rectifier unit is a device that converts alternating current into direct current, which can convert the alternating current (AC) generated by the motor element 4 into direct current (DC), and then supply it to the voltage conversion unit 32. The rectifying unit 31 can be made of vacuum tubes, ignitrons, solid-state silicon semiconductor diodes, mercury arcs, etc.

[0071] Exemplarily, the voltage conversion unit 32 is a DC-to-DC converter, or simply called a DC-DC converter, which can be a circuit structure that can convert the direct current generated by the motor element 4 into direct current with different voltages to meet the charging level of the battery module 1.

[0073] Using the first switching element 22, the on / off of the power supply circuit 2 can be controlled to realize the switching between the power consumption mode and the charging mode of the mobile terminal. When the first switching element 22 is closed, the power supply circuit 2 is turned on, and the mobile terminal operates in the power consumption mode. The electric energy in the battery module 1 is input into the motor element 4 through the driving unit 21, and the motor element 4 converts the electric energy into mechanical energy to achieve the target functions of the electronic device (such as camera focusing, camera anti-shake, vibration, etc.). When the first switching element 22 is opened, the power supply circuit 2 is disconnected, and at this time, it may be in the charging mode.

[0074] Exemplarily, the first switching element 22 is located between the driving unit 21 and the battery module 1; alternatively, the first switching element 22 is located between the driving unit 21 and the motor element 4. Optionally, the first switching element 22 is located between the driving unit 21 and the battery module 1, which is beneficial to avoid interference caused by the driving unit 21 in the charging mode. Another exemplarily, the first switching element 22 is integrated into the driving unit 21, and while the driving unit 21 realizes its own functions, it controls the on and off of the power supply circuit 2.

[0075] Combined with Figure 2 As shown, in some embodiments, the charging circuit 3 further includes at least one second switching element 33; at least one second switching element 33 is located between the rectifying unit 31 and at least one motor element 4, and / or at least one second switching element 33 is located between the voltage conversion unit 32 and the battery module 1.

[0076] Using the second switching element 33, the on / off of the charging circuit 3 can be controlled to realize the switching between the power consumption mode and the charging mode of the mobile terminal. When the second switching element 33 is closed, the charging circuit 3 is turned on, and the mobile terminal operates in the charging mode. The motor element 4 has mechanical energy under the action of an external force, and converts the mechanical energy into electric energy through electromagnetic induction. The electric energy is processed by the rectifying unit 31 and the voltage conversion unit 32 and then input into the battery module 1.

[0077] Exemplarily, the second switching element 33 is located between the voltage conversion unit 32 and the battery module 1; alternatively, the second switching element 33 is located between the rectifying unit 31 and the motor element 4. Optionally, the second switching element 33 is located between the voltage conversion unit 32 and the battery module 1, which is beneficial to avoid interference caused by the voltage conversion unit 32 and the rectifying unit 31 in the power consumption mode.

[0078] Combined with Figure 2 、 3 and Figure 4 As shown, in some embodiments, the motor element 4 includes an induction coil 41 and an induction magnet 42; the induction coil 41 and the induction magnet 42 are arranged to move relative to each other, one of the induction coil 41 and the induction magnet 42 is fixed in position, and the induction coil 41 is electrically connected to the power supply circuit 2 and the charging circuit 3 respectively.

[0079] With the above arrangement, in the power consumption mode, the power supply circuit 2 is turned on, the induction coil 41 is energized, the induction coil 41 generates an electromagnetic field, and the electromagnetic field interacts with the magnetic field of the induction magnet 42 to drive the induction coil 41 or the induction magnet 42 to move, thereby realizing the conversion of electrical energy into mechanical energy. In the charging mode, the charging circuit 3 is turned on. Under the action of an external force, the induction coil 41 or the induction magnet 42 obtains mechanical energy, the induction coil 41 cuts the magnetic induction line, and an induced current is generated therein. After being processed by the rectification unit 31 and the voltage conversion unit 32, the induced current meets the charging level of the battery module 1, realizing the charging of the battery module 1.

[0080] Exemplarily, the induction coil 41 is connected to the moving part in the motor element 4, and the induction magnet 42 is connected to the fixed part in the motor element 4. When the moving part moves under the action of an external force, it drives the induction coil 41 to move, realizing the conversion of mechanical energy and electrical energy.

[0081] Combined with Figure 3 、 4 As shown, in some embodiments, at least one motor element 4 is located in the camera module 5; the camera module 5 includes a lens assembly 51 and a support assembly 52 arranged movably; one of the induction coil 41 and the induction magnet 42 is located on the lens assembly 51, and the other of the induction coil 41 and the induction magnet 42 is located on the support assembly 52.

[0082] In this embodiment, the induction coil 41 and the induction magnet 42 of the motor element 4 are respectively arranged on the lens assembly 51 and the support assembly 52 of the camera module 5. In the power consumption mode, the motor element 4 can drive the lens assembly 51 to move relative to the support assembly 52 to realize the focusing or anti-shake of the camera module 5. In the charging mode, the lens module can drive the induction coil 41 of the motor element 4 to cut the magnetic induction line of the induction magnet 42 to realize the charging of the battery module 1.

[0083] Exemplarily, the induction coil 41 is located on the lens assembly 51, and the induction magnet 42 is located on the support assembly 52; or, the induction coil 41 is located on the support assembly 52, and the induction magnet 42 is located on the lens assembly 51.

[0084] Combined with Figure 3 、 4 As shown, in some embodiments, the support assembly 52 is provided with a receiving cavity 521, the lens assembly 51 is located in the receiving cavity 521, and the lens assembly 51 moves along the axis of the receiving cavity 521; the induction magnet 42 is located on the inner side surface of the receiving cavity 521, and the induction coil 41 is located on the outer side surface of the lens assembly 51. Among them, Figure 3 shows the state where the lens assembly 51 drives the induction coil 41 to move upward along the axis, Figure 4shows the state in which the lens assembly 51 drives the induction coil 41 to move axially downward. The lens assembly 51 can drive the induction coil 41 to reciprocate between Figure 3 and Figure 4 two states.

[0085] With the above arrangement, in the power consumption mode, the motor element 4 can drive the lens assembly 51 to move relative to the support assembly 52, realizing the focusing or anti-shake of the camera module 5. In the charging mode, the lens module can drive the induction coil 41 of the motor element 4 to cut the magnetic induction lines of the induction magnet 42, realizing the charging of the battery module 1.

[0086] With the continuous improvement of the performance requirements of the camera module 5, the size and mass of the lens assembly 51 are getting larger and larger, and the kinetic energy generated by the lens assembly 51 is also getting larger and larger. That is, the mechanical energy generated by the lens assembly 51 driving the induction coil 41 is increasing. In the charging mode, the mechanical energy can be converted into electrical energy to charge the battery module 1, thereby improving the battery life of the mobile terminal.

[0087] Combined with Figure 5 shown, in some embodiments, the mobile terminal further includes a terminal body 6, and the axis of the accommodation cavity 521 is parallel to the thickness direction of the terminal body 6; when the terminal body 6 reciprocates along the thickness direction, the lens assembly 51 drives the induction coil 41 to move relative to the induction magnet 42, and at least one motor element 4 converts the mechanical energy of the lens assembly 51 and the induction coil 41 into electrical energy and inputs the electrical energy into the battery module 1.

[0088] By arranging the moving directions of the lens assembly 51 and the support assembly 52 in the camera module 5 parallel to the thickness direction of the terminal body 6, when the terminal body 6 reciprocates along the thickness direction (such as manual shaking), the lens assembly 51 moves axially under its own inertia or relative to the support assembly 52, thereby driving the induction coil 41 to cut the magnetic induction lines of the induction magnet 42 to generate an induced current, realizing the charging of the battery module 1.

The photosensitive element is coaxially arranged with the lens assembly 51 and is located on the light-emitting side of the lens assembly 51, capable of receiving the light input by the lens assembly 51 to achieve photosensitive imaging. The connection circuit board 54 is connected to the photosensitive element, and a plurality of plated circuits are provided on the connection circuit board 54, where at least one plated circuit forms part of the power supply circuit 2 and at least one plated circuit forms part of the charging circuit 3.
