[0024] The following will describe in detail some embodiments of the present disclosure with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0025] As Figures 1 to 3As shown in the figure, the mobile terminal 100 according to an embodiment of the present disclosure includes a terminal body 1, a functional component 20, and a driving device 30. The driving device 30 cooperates with the functional component 20 to control the functional component 20 to protrude from the terminal body 1 or be received in the terminal body 1.

[0026] That is to say, the functional component 20 of the present disclosure can be controllably moved within the terminal body 1. When the functional component 20 is not needed, the driving device 30 is used to control the functional component 20 to be received in the terminal body 1, and at this time, the functional component 20 is hidden within the terminal body 1. When the functional component 20 needs to be used, the driving device 30 is used to control the functional component 20 to protrude from the terminal body 1 for the user to use the functional component 20. The functional component 20 of the present disclosure is a front camera module. By changing the camera conventionally disposed on the front of the display screen to be controllably moved in and out from the side of the terminal body 1, the requirement of a high screen-to-body ratio can be met, and thus the design of a full-screen can be further realized.

[0027] The terminal body 1 includes a middle frame housing 11, and a processor and a position detection module located within the middle frame housing 11. Among them, the processor is configured to: confirm the position of the functional component 20 according to the feedback information of the position detection module. In this embodiment, the position detection device is used to detect the functional component 20, specifically obtain different position information of the functional component 20, and the position information at least includes the position information of the functional component 20 protruding from the middle frame housing 11 or being received in the middle frame housing 11; then the position information (i.e., the feedback information) is sent to the processor, so that the position information of the functional component 20 can be confirmed. It should be noted that the protrusion from the middle frame housing 11 or the terminal body 1 as described in the present disclosure means that the functional component 20 protrudes to the maximum extent for the user to use.

[0028] The functional component 20 of the present disclosure includes a camera module. The camera module includes a module body 22, at least one camera 21 disposed on the module body 22, and a flexible circuit board 23 extending from the module body 22. In this embodiment, two cameras 21 are provided on the module body 22 to enhance the shooting effect. In addition, sensors and / or photosensitive elements, etc. may also be provided on the module body 22. The flexible circuit board 23 is electrically connected to a control circuit board 13 within the middle frame housing 11 to enable the camera 21 to be communicatively connected to the control circuit board 13. Among them, the flexible circuit board 23 has a certain movable length to meet the movement of the functional component 20.

[0029] In another embodiment, the functional component 20 may further include a card tray mechanism for assembling a SIM card (Subscriber Identification Module) or a memory card, etc. The card tray of the card tray mechanism is cooperated with the driving device 30 of the present disclosure, so that the card tray can be intelligently controlled to pop out from the side of the terminal body or automatically retract. The specific structural features of the driving device 30 are as shown in the above embodiments and will not be described herein again.

[0030] Among them, in the description and illustration of the present disclosure, the functional component 20 takes the camera module as an example for specific introduction. The camera module pops out from the side of the terminal body 1 and is hidden in the terminal body 1 in the non-working state, which will not affect the appearance of the mobile terminal 100, completely avoids and does not occupy the space of the display screen in the display module, so as to achieve the full-screen display effect.

[0031] The middle frame housing 11 may include a frame and a bottom case. The bottom case may be integrally formed with the frame or assembled to the frame in a detachable manner. The entrance of the receiving groove 12 is provided on the frame. The functional component 20 can be moved out from the frame or flush with the frame after being retracted. A control circuit board 13 is provided in the terminal body 1. The functional component 20 and the driving device 30 are respectively communicatively connected to the control circuit board 13. A processor (not shown) and a plurality of functional devices are provided on the control circuit board 13. Among them, the processor is used to control the rotation of the driving member 31 according to the received control signal, so as to control the movement of the functional component 20 through the driving device 30, that is, to drive the functional component 20 to protrude from the terminal body 1 or be received in the terminal body 1. The control signal may be a touch signal of a user touching the camera or video function module on the mobile phone or an associated APP.

[0032] Specifically, the position detection module includes a first detection module 41 for detecting the state that the functional component 20 protrudes from the middle frame housing 11 and a second detection module 42 for detecting the state that the functional component 20 is received in the middle frame housing 11. In the present disclosure, the first detection module 41 and the second detection module 42 are cooperated to respectively detect different positions of the functional component 20, so that the use state of the functional component 20 can be confirmed.

[0033] Further, the driving device 30 of the present disclosure includes a driving member 31, a transmission mechanism 32 cooperating with the driving member 31, and a connecting member 33 respectively connected to the functional component 20 and the transmission component 323. Among them, through the cooperation of the driving member 31 and the transmission mechanism 32, the connecting member 33 is controlled to move, so as to control the functional component 20 to protrude from the middle frame housing or be received in the middle frame housing, that is, to control the functional component 20 to protrude from the middle frame housing 11 or be received in the middle frame housing 11.

[0034] Among them, the driving member 31 of the present disclosure is a stepper motor. Since the resistance that the functional component 20 needs to overcome during the starting motion is greater than that during the smooth motion, the control method is optimized, and the driving member 31 adopts a segmented control. In one example, the stepper motor starts at a driving frequency of 800 pps, obtains a pushing force of about 390 gf, can cope with the starting resistance in most cases, and drives the motor to move 60 steps; then switches to a driving frequency of 1600 pps as a transition, and drives the motor to move 160 steps; finally, moves smoothly at a frequency of 2400 pps, and drives the motor to move 2400 steps. Overall, the motion time is 1.175 s. In this way, the precise control of the functional component 20 can be satisfied, and the functional component 20 can be quickly protruded or retracted.

[0035] The transmission mechanism 32 of the present disclosure includes a base 324, a lead screw 321 connected to the base 324, and a transmission component 323 connected to the driving member 31 and the lead screw 321. Among them, one end of the connecting member 33 is connected to the functional component 20, and the other end of the connecting member 33 is assembled on the lead screw 321. The connecting member 33 can be driven by the lead screw 321 to move axially along the lead screw 321. Specifically, the driving member 31 drives the lead screw 321 to rotate through the transmission component 323, and then the connecting member 33 moves axially on the lead screw 321 by the rotation of the lead screw 321, so as to control the functional component 20 to protrude out of the middle frame housing 11 or be received in the middle frame housing 11. In one embodiment, the transmission component 323 is a combination of gears or a combination of a transmission belt and a transmission wheel. In this embodiment, a gear combination is selected between the driving member 31 and the lead screw 321. In order to protect the gear combination, a gear box is further provided between the driving member 31 and the lead screw 321, and the driving force of the driving member 31 is transmitted to the lead screw 321 through the cooperation of multiple gears, so that the lead screw 321 rotates.

[0036] Furthermore, the transmission mechanism 32 further includes a guide rail 322 arranged parallel to the lead screw 321. The connecting member 33 further includes a connecting portion (not shown) slidably connected to the guide rail 322. The connecting portion is sleeved or partially sleeved on the guide rail 322 and can slide along the guide rail 322. Among them, the base 324 has a U-shaped structure, the lead screw 321 can be rotatably connected to two opposite side walls of the base 324, and the guide rail 322 is fixed on the two opposite side walls. In this embodiment, the lead screw 321 and the connecting member 33 are cooperated to enable the lead screw 321 to provide operating power for the connecting member 33, and the sliding of the second connecting portion and the guide rail 322 can increase the stability of the connection between the connecting member 33 and the transmission mechanism 32, and also increase the sliding stability of the connecting member 33.

[0037] Such as Figures 1 to 3As shown, in one embodiment, the first detection module 41 and the second detection module 42 determine the position of the functional component 20 by detecting the moving position of the connecting member 33. Among them, the first detection module 41 and the second detection module 42 are respectively arranged at both ends of the base 324. Specifically, when the connecting member 33 moves to the detection position where the first detection module 41 is located, at this time the connecting member 33 blocks the detection path of the first detection module 41, and the first detection module 41 can detect the connecting member 33, so as to determine the position where the functional component 20 is located, and send the signal to the processor; when the connecting member 33 moves to the detection position where the second detection module 42 is located, at this time the connecting member 33 blocks the detection path of the second detection module 42, and the second detection module 42 can detect the connecting member 33, so as to determine the position where the functional component 20 is located, and send the signal to the processor. In this embodiment, the first detection module 41 and the second detection module 42 are one of a distance sensor, an infrared sensor, an acoustic wave sensor, etc.

[0038] Of course, the first detection module 41 and the second detection module 42 are not limited to being installed at both ends of the base 324 and are not limited to detecting the connecting member 33. The first detection module 41 and the second detection module 42 can also be installed at any position on the movement path of the functional component 20 and cooperate with any structural member on the functional component 20 for detection.

[0039] The following takes the first detection module 41 and the second detection module 42 selecting infrared sensors as an example for description. When the connecting member 33 moves to block the first detection module 41 or the second detection module 42, a light interruption signal will be generated and sent to the processor, and then the processor will take corresponding actions. Specifically, when the second detection module 42 at the starting position is in the blocked state and the first detection module 41 at the ending position is in the open state, the functional component 20 is in the retracted state, that is, the functional component 20 is housed in the middle frame housing. At this time, if the user needs to use the front camera function, the processor will drive the stepping motor to perform the extension action. When the second detection module 42 at the starting position is in the open state and the first detection module 41 at the ending position is in the blocked state, the functional component 20 is in the state of protruding for use. At this time, if the software recognizes that the user has finished using the front camera function or the user actively retracts the functional component 20, the processor will drive the stepping motor to reverse and perform the retraction action.

[0040] Such as Figure 1 、 Figure 2 and Figure 4As shown, in another embodiment, an induction module 24 cooperating with the first detection module 41 and the second detection module 42 is provided on the functional component 20. Among them, when the processor receives the induction signal between the first detection module 41 and the induction module 24, it is determined that the functional component 20 is in a state of protruding from the middle frame housing 11; when the processor receives the induction signal between the second detection module 42 and the induction module, it is determined that the functional component 20 is in a state of being received in the middle frame housing 11. Optionally, the first detection module 41 and the second detection module 42 are electronic compasses provided beside the functional component 20, and the induction module is a magnet; among them, the processor determines the position of the functional component 20 according to the detected magnetic force strength.

[0041] In this embodiment, the magnet is fixed on the functional component 20, and then two electronic compasses are connected to the control circuit board 13. The two electronic compasses can be electrically connected to the control circuit board 13 through surface mount technology, and then the magnetic force curve of the magnet is detected. According to the detected magnetic force strength, the peak value is taken as the detection point to output an electrical signal to the processor, so that the processor performs corresponding operations.

[0042] Furthermore, the processor of the present disclosure is further configured to: if no feedback information is received within a preset time, it is determined that the transmission mechanism 32 is in a stuck state. Usually, the functional component 20 is in a state of protruding from the middle frame housing 11 or being received in the middle frame housing 11, and there is also a rated movement time during the state switching process between the two. In this embodiment, by monitoring the state switching time of the functional component 20 by the processor, the operation stability of the functional component 20 is ensured. When a stuck problem occurs, the processor can also control the alarm device to give an alarm to remind the user to repair it in time.

[0043] The mobile terminal 100 further includes a display module 10 assembled on the front of the terminal body 1. The display module 10 generally includes a backlight module, a display panel, and a touch panel. Preferably, the display module 10 includes a full-screen, that is, the display module 10 is set as a full-screen. In this embodiment, function modules such as the camera 21, sensors (one or more of various types of sensors, such as: infrared sensors, light sensors, distance sensors, etc.), and photosensitive elements provided on the front of the display screen are no longer provided on the display module 10, so that the display module 10 can achieve a high screen-to-body ratio or a full-screen for the display screen. Among them, function modules such as sensors and photosensitive elements can be provided on the frame of the terminal body 1.

[0044] Among them, a receiving groove 12 adapted to the functional component 20 is provided at the top end of the terminal body 1. The functional component 20 is movably received in the receiving groove 12, and the position of the receiving groove 12 can correspond to any position at the top end of the terminal body 1. Of course, the receiving groove 12 is not limited to being provided at the top end of the terminal body 1, and can also be provided on other sides of the terminal body 1, that is, the functional component 20 can also be moved out from both side surfaces of the middle frame housing 11 or from the bottom end of the middle frame housing 11. According to the user's usage habit, the present disclosure preferably moves out from the top end of the terminal body 1.

[0045] In this embodiment, when the functional component 20 is received in the receiving groove 12, the upper surface of the functional component 20 is flush with the top surface of the terminal body 1. In this way, when the functional component 20 is received in the receiving groove 12, the upper surface of the functional component 20 constitutes a part of the terminal body 1, thus not affecting the appearance of the mobile terminal 100.

[0046] The mobile terminal 100 in the present disclosure can be an electronic device such as a mobile phone, a tablet computer, a handheld computer, a personal digital assistant (Personal Digital Assistant, abbreviated as: PDA), etc. In the present disclosure, the mobile terminal 100 is specifically described by taking a mobile phone as an example. Among them, it should be noted that the top end of the terminal body 1 is the upper end part of the mobile phone when holding the mobile phone according to the user's usage habit.

[0047] In one embodiment, the mobile terminal 100 further includes a flash lamp (not shown), and the flash lamp is provided on the module body 22. When the mobile terminal 100 needs to use the front camera function, the flash lamp can assist the camera 21 with lighting, thereby improving the experience of self-taking pictures or video calls.

[0048] The mobile terminal of the present disclosure movably arranges the functional component in the terminal body. By protruding the functional component of the camera module from the terminal body, the camera can be moved to the front of the terminal body to make up for the lack of a front camera. When the front camera function (such as self-taking pictures or video calls) is not needed, the functional component is completely received in the terminal body, and the camera can be hidden in the terminal body. The present disclosure designs a position detection module that cooperates with the functional component to achieve closed-loop control of the protruding movement of the functional component, making the control scheme more simplified and capable of coping with more complex usage scenarios.
