Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

Referring to fig. 1 and fig. 2, in the technical solution provided in the embodiment of the present invention, the mobile terminal includes a housing 10, a power source 20, a deformation component 30, an elastic component 40, and an optical assembly 50. The shell 10 is provided with an opening, the power supply 20, the deformation component 30, the elastic component 40 and the optical assembly 50 are all accommodated in the shell 10, the elastic component 40 is attached to one side of the deformation component 30, and the optical assembly 50 is abutted against one side of the elastic component 40, which is opposite to the deformation component 30; the shape-changing component 30 is connected to the power source 20, and the shape-changing component 30 is deformed in the power-on state, so that the elastic component 40 generates mechanical vibration to drive the optical assembly 50 to at least partially extend out of the opening or retract into the housing 10.

It is understood that the deformation member 30 is deformed when it is energized; as an optional implementation manner, the deformation component 30 may be a piezoelectric ceramic, the upper and lower surfaces of the piezoelectric ceramic have electrodes, and the piezoelectric ceramic also has a polarization direction; when an electric field in the same direction as the polarization direction is applied to the piezoelectric ceramic, the polarization strength is increased, and the piezoelectric ceramic is subjected to extension deformation; when an electric field opposite to the polarization direction is applied to the piezoelectric ceramic, the polarization strength is reduced, and the piezoelectric ceramic is shortened and deformed.

The power supply in the embodiment of the present invention is not only a battery for supplying power to the deformation component, but also may include a power manager, or a general name that a motherboard and the like are connected to the battery, where the motherboard may carry various electronic components of the mobile terminal, such as various circuit modules, wires, and a battery, and a specific circuit connection relationship and a signal transmission principle of the motherboard may refer to the existing scheme, which is not described herein again. For example, bear the weight of camera circuit module on the mainboard, and then just also can come the output of control voltage signal to the deformation part according to the signal of camera circuit module to make the deformation part take place to deform.

Wherein, the deformation component 30 generates a first deformation in a first power-on state, so that the elastic component 40 generates a first mechanical vibration to drive the optical component 50 to at least partially protrude out of the opening; the deformation component 30 generates a second deformation in the second energized state, so that the elastic component 40 generates a second mechanical vibration to drive the optical assembly 50 to retract into the housing 10.

The optical assembly 50 may be a device including a camera, a flash, a photosensitive sensor, an infrared sensor, etc. which needs to collect light.

As a preferred implementation of the present embodiment, the optical assembly 50 includes at least a camera 60. For example, when the optical assembly 50 is accommodated in the housing 10, if the mobile terminal receives an input operation of popping up the camera triggered by a user, such as an input operation of starting a self-timer, the mobile terminal controls the power supply to energize the deformation component 30, so that the deformation component 30 is in a first energized state, the deformation component 30 generates a first deformation in the first energized state, so that the elastic component 40 generates a first mechanical vibration, and then the optical assembly 50 is driven to move to make the camera 60 extend out of the opening and expose outside the housing 10, so as to facilitate the user to realize self-timer. It should be noted that, after the optical assembly 50 moves to the position where the camera is exposed outside the housing 10, the power supply may stop supplying power to the deformation component 30, and the deformation component 30 stops deforming, so that the elastic component 40 stops vibrating, and the optical assembly 50 is not driven forward continuously, so as to ensure smooth shooting.

When the camera on the optical assembly 50 is exposed outside the housing 10, if the mobile terminal receives an input operation triggered by a user to finish shooting, the mobile terminal controls the power supply to energize the deformation component 30, so that the deformation component 30 is in a second energized state, and the deformation component 30 generates a second deformation in the second energized state, so that the elastic component 40 generates a second mechanical vibration, and then the optical assembly 50 is driven to move, so that the camera 60 retracts into the housing 10 from the opening.

Like this, be in different on-state through control deformation part 30, just also can control optical assembly 50's direction of motion pertinence ground, and then just also make optical assembly 50 can move when needs use outside the casing 10 and realize functions such as daylighting, shooting, just also need not just also to set up the light trap on mobile terminal's display screen, optical assembly 50 can not occupy the display area of display screen on the mobile terminal, the screen that has improved mobile terminal accounts for the ratio, more is favorable to mobile terminal to comprehensive screen development.

The first and second energized states may be voltages applied to the piezoelectric ceramic, and the piezoelectric ceramic may be alternately deformed due to expansion and contraction caused by the energization of the piezoelectric ceramic. The deformation component 30 comprises N deformation units, and each deformation unit is connected with the power supply 20; in a first energized state, and in a second energized state: the voltage polarities of any two adjacent deformation units in the same time unit are opposite, and the voltage polarities of the same deformation unit in any two adjacent time units are opposite; the voltage polarity of each deformation unit in the initial time unit in the first electrifying state is opposite to the voltage polarity of each deformation unit in the initial time unit in the second electrifying state; the arbitrary shape change unit is in an extended state at a first polarity voltage and in a shortened state at a second polarity voltage, and the first polarity voltage and the second polarity voltage have opposite polarities.

As a specific implementation, referring to fig. 3, it is assumed that the deformation member 30 (piezoelectric ceramic) includes 4 deformation units: a first deformation unit 31, a second deformation unit 32, a third deformation unit 33 and a fourth deformation unit 34. In the first power-on state, the first deformation unit 31 is a forward voltage signal in the initial unit time, the second deformation unit 32 is a reverse voltage signal in the initial unit time, the third deformation unit 33 is a forward voltage signal in the initial unit time, the fourth deformation unit 34 is a reverse voltage signal in the initial unit time, and the deformation states of the four deformation units in the initial unit time are respectively elongation, shortening, elongation and shortening; if the first energization state is an ac voltage, then the first deformation unit 31 is a reverse voltage signal in the second unit time, the second deformation unit 32 is a forward voltage signal in the second unit time, the third deformation unit 33 is a reverse voltage signal in the second unit time, the fourth deformation unit 34 is a forward voltage signal in the second unit time, and the deformation states of the four deformation units in the second unit time are respectively shortening, lengthening, shortening, and lengthening; and each deformation unit deforms according to the rule in the preset unit time. The above is the first deformation of the piezoelectric ceramic generated in the first energization state. Therefore, the deformation units of the piezoelectric ceramic alternately extend and shorten deformation in unit time, and any one deformation unit alternately extends and shortens deformation in a preset period of unit time.

According to the rule, the deformation unit of the piezoelectric ceramic can alternately generate periodical extension and shortening deformation according to the change of the voltage signal in the first electrified state. In the embodiment of the present invention, the elastic component 40 and the deformation component 30 may be bonded, referring to fig. 4, the deformation of the piezoelectric ceramic will make the elastic component 40 bonded on one side generate the first mechanical vibration with waveform, and the elastic component 40 will not move relative to the piezoelectric ceramic; the vibration of the elastic member 40, i.e., the ultrasonic vibration that can make any point of the optical component 50 attached to one side of the elastic member 40 follow the elliptical trajectory in fig. 4, causes the optical component 50 to move along the first propagation direction of the vibration wave formed by the first vibration, i.e., the moving direction of the optical component 50 moving out of the opening, through the friction action between the elastic member 40 and the optical component 50.

Based on the deformation law of above-mentioned piezoceramics under first circular telegram state, the deformation state that the deformation unit of piezoceramics takes place is relevant in the initial unit interval for the first propagation direction of the vibration wave that elastic component 40's first vibration formed, and the deformation state of deformation unit in initial unit interval is decided by the applied voltage direction, and then can know, through controlling voltage signal, just also can control optical assembly 50's direction of motion, with the deformation state through to piezoceramics controls, so that elastic component 40 produces first vibration, and then drive optical assembly 50 drives camera 60 and moves to exposing outside the opening.

Referring to fig. 2, in the second power-on state, the first deformation unit 31 is a reverse voltage signal in the initial unit time, the second deformation unit 32 is a forward voltage signal in the initial unit time, the third deformation unit 33 is a reverse voltage signal in the initial unit time, and the fourth deformation unit 34 is a forward voltage signal in the initial unit time, and the deformation states of the four deformation units in the initial unit time are respectively shortened, lengthened, shortened and lengthened; if the first energization state is an ac voltage, the first deformation element 31 is a forward voltage signal in the second unit time, the second deformation element 32 is a reverse voltage signal in the second unit time, the third deformation element 33 is a forward voltage signal in the second unit time, the fourth deformation element 34 is a reverse voltage signal in the second unit time, and the deformation states of the four deformation elements in the second unit time are respectively elongation, contraction, elongation, and contraction. The above is the second deformation of the piezoelectric ceramic generated in the second energized state. Therefore, the deformation units of the piezoelectric ceramic alternately extend and shorten deformation in unit time, and any one deformation unit alternately extends and shortens deformation in a plurality of unit time periods.

According to the rule, the deformation unit of the piezoelectric ceramic can alternately generate periodic extension and shortening deformation according to the change of the voltage signal in the second electrifying state; the deformation of the piezoelectric ceramic can make the elastic component 40 adhered to one side generate second vibration in a waveform, and also can make any point of the optical component 50 adhered to one side of the elastic component 40 generate ultrasonic vibration according to an elliptical track, and this vibration passes through the friction action between the elastic component 40 and the optical component 50, so that the optical component 50 can move along a second propagation direction of a vibration wave formed by the second vibration, and this second propagation direction is also the movement direction in which the optical component 50 drives the camera 60 to move towards the inside of the housing 10.

Based on the above deformation rule of the piezoelectric ceramic in the second energized state, the second propagation direction of the vibration wave formed by the second vibration of the elastic component 40 is related to the deformation state of the deformation unit of the piezoelectric ceramic in the initial unit time, and the deformation state of the deformation unit in the initial unit time of the second energized state is opposite to the deformation state in the initial unit time of the first energized state, so that in the second energized state, the second propagation direction of the vibration wave formed by the second vibration of the elastic component 40 is opposite to the first propagation direction, and further the elastic component 40 can drive the movement direction of the optical component 50 to be consistent with the second propagation direction, so as to drive the camera 60 to move to be accommodated in the housing 10.

In the embodiment of the present invention, the optical assembly 50 includes a base 52 and a connecting member 51 disposed on one side of the base 52, the camera 60 is disposed on the base 52, one side of the connecting member 51 facing away from the base 52 abuts against one side of the elastic member 40 facing away from the deformation member 30, and a friction coefficient between the connecting member 51 and the elastic member 40 is greater than a friction coefficient between the base 52 and the connecting member 51. The connecting member 51 may be bonded to the base 52, and when the elastic member 40 generates the first vibration or the second vibration, based on a larger friction coefficient between the elastic member 40 and the connecting member 51, a larger friction force may be generated, and the elastic member 40 may drive the connecting member 51 to move, so as to drive the base 52 and the connecting member 51 bonded to one side of the connecting member 51 to move simultaneously, so as to drive the camera 60 to move to be exposed outside the housing 10 or accommodated in the housing 10.

As a specific implementation manner, the connecting member 51 is made of nano carbon. It can be understood that the surface and interface characteristics of the connecting member 51 made of the nanocarbon material are more excellent, so that the side, where the connecting member 51 is attached to the elastic member 40, has a higher friction coefficient, and further, the elastic member 40 can have a higher friction force when vibrating, and thus, the elastic member 40 can have a higher driving force for the connecting member 51 and the base 52 bonded to the connecting member 51.

Optionally, the camera 60 is a front-facing camera 60, that is, when the camera 60 moves to be exposed outside the housing 10, the camera 60 is used for acquiring an image of the display screen side of the mobile terminal, and when the image of the display screen side does not need to be acquired, the camera 60 is accommodated in the housing 10. Therefore, the camera 60 does not need to occupy the display area of the display screen on the mobile terminal, the screen occupation ratio of the mobile terminal is improved, and the mobile terminal is more favorable for the development of the comprehensive screen.

It should be noted that, the camera 60 may also be connected with a driving mechanism, the driving mechanism is connected with the power supply 20, and the driving mechanism can drive the camera 60 to rotate so as to acquire images at different angles. The driving mechanism may be a motor, and the camera 60 is driven to rotate forward or backward by the forward rotation and backward rotation of the motor.

According to the technical scheme provided by the embodiment of the invention, the deformation component 30 can deform under the condition of electrification, so that the elastic component 40 generates vibration, and further the vibration of the elastic component 40 can drive the optical assembly 50 to move and expose outside the shell 10 or move and be accommodated in the shell 10. Like this, also make optical assembly 50 can move outside casing 10 when needs use and realize functions such as daylighting, shooting, also just also need not to set up the light trap just, optical assembly 50 can not occupy the display area of display screen on the mobile terminal, has improved mobile terminal's screen and has occupied than, more is favorable to mobile terminal to the development of full screen.

As an optional implementation manner, the deformation component may be piezoelectric ceramic, electrodes are disposed on the upper and lower surfaces of the piezoelectric ceramic, and the piezoelectric ceramic also has a polarization direction; when an electric field in the same direction as the polarization direction is applied to the piezoelectric ceramic, the polarization strength is increased, and the piezoelectric ceramic generates sound and is elongated and deformed; when an electric field opposite to the polarization direction is applied to the piezoelectric ceramic, the polarization intensity is reduced, and the piezoelectric ceramic sounds and shortens deformation.
