Referring to fig. 3, 4, 5 and 6, fig. 3 is a schematic perspective view of the lens lifting androtating device 1 shown in fig. 1 in a retracted state; fig. 4 is a schematic perspective view of the extended state of the lens barrel elevating androtating apparatus 1 shown in fig. 1; fig. 5 is a perspective view illustrating a right rotation state of the lens barrel elevating androtating apparatus 1 shown in fig. 1; fig. 6 is a schematic perspective view of the lens barrel elevating/rotating device 1 shown in fig. 1 in a left-rotated state. The following describes four different states of the lens raising/lowering/rotating device 1 and the change process between the states with reference to fig. 3, 4, 5 and 6. First, as shown in fig. 3, when the lens lifting/rotating device 1 is in the retracted state, theslider 34 is sleeved on one end of thefirst screw 33 adjacent to the drivingunit 21, the drivingunit 21 does not drive thefirst screw 33 to rotate, thesecond portion 342 of theslider 34 clamps theshaft sleeve 342b and makes the firstelastic element 312 in the extended state, so as to apply a pulling force to the supportingstructure 35, and meanwhile, thefirst portion 341 of theslider 34 is further connected to thelens module 10 through thesecond transmission assembly 32, so that the supportingstructure 35 and thelens module 10 above the supportingstructure 35 are in the retracted state of being retracted in the accommodating space of thehousing 41.

Further, when the lens lifting androtating device 1 is needed to be used and thelens module 10 is extended out of the accommodating space of thehousing 41, themotor 211 of the drivingunit 21 rotates and drives thefirst screw 33 to rotate, and under the condition that the position of thefirst screw 33 is not changed because thefirst screw 33 is connected with theslider 34 through the first threadedhole 341a, theslider 34 can move toward the side where thelens module 10 is located along thefirst screw 33, further, thesecond portion 342 of theslider 34 clamps theshaft sleeve 342b and gradually changes the firstelastic element 312 into a compressed state to push the supportingstructure 35 and thelens module 10 above the supporting structure, and meanwhile, thefirst portion 341 of theslider 34 also pushes thelens module 10 through thesecond transmission assembly 32, so that thelens module 10 is gradually extended out of the accommodating space of thehousing 41. As shown in fig. 4, when thelens assembly 11 of thelens module 10 completely extends out of the accommodating space, the two ends of the supportingstructure 35 also abut against thehousing 41, specifically, theelectromagnetic assembly 37 of the supportingstructure 35 and the magnetic steel inside thehousing 41 are attracted together to fix the position of the supportingstructure 35, so that thelens module 10 can maintain the extended state. When theelectromagnetic assembly 37 is an electromagnetic valve, the electromagnetic valve can be electrified through signal control, so that one end of the electromagnetic valve, which is in contact with the magnetic steel, generates magnetism which is attracted with the magnetic steel, and the magnetic steel and theelectromagnetic assembly 37 are attracted and fixed.

Further, on the basis of the extended state shown in fig. 4, when thelens module 10 needs to rotate in one direction (for example, to the right), the drivingunit 21 further drives thefirst screw 33 to rotate, so that the slidingblock 34 slides (for example, slides downwards) along thefirst screw 33, at this time, since the positions of the supportingstructure 35 and thetransmission shaft 311 connected to the supportingstructure 35 are fixed by the twomagnetic elements 37, the movement of the slidingblock 34 will drive thesecond screw 321 to rotate, and further drive thelens module 11 to rotate (for example, rotate towards the right) through thefirst gear 322 and thesecond gear 13, so as to realize the rotation of thelens module 11, and then thelens module 10 reaches the first rotation state shown in fig. 5, and when the proper shooting angle is reached, the drivingunit 21 can be controlled to stop rotating, so that thelens module 11 maintains the proper shooting angle for shooting.

Similarly, on the basis of the extended state shown in fig. 4 or fig. 5, when thelens module 10 needs to rotate in one direction (for example, on the left), the drivingunit 21 further drives thefirst screw 33 to rotate, so that the slidingblock 34 slides (for example, slides upwards) along thefirst screw 33, at this time, since the positions of the supportingstructure 35 and thetransmission shaft 311 connected to the supportingstructure 35 are fixed by the twomagnetic assemblies 37, the movement of the slidingblock 34 will drive thesecond screw 321 to rotate, and further drive thelens module 11 to rotate (for example, rotate towards the left) through thefirst gear 322 and thesecond gear 13, so as to realize the rotation of thelens module 11, and then thelens module 10 reaches the second rotation state shown in fig. 6, and when the proper shooting angle is reached, the drivingunit 21 can be controlled to stop rotating, so that thelens module 11 maintains the proper shooting angle for shooting.

Furthermore, when the lens module 10 is taken or the lens module 10 is not needed to be used and the lens module 10 outside the extended accommodating space needs to be retracted, the driving unit 21 further drives the first screw 33 to rotate, so that the slider 34 slides along the first screw 33, the lens assembly 11 of the lens module 10 shown in fig. 5 or 6 is firstly rotated to the extended state shown in fig. 4, then the electromagnetic valve is controlled by a signal to pass through a reverse current, the magnetic pole is reversed, the end of the electromagnetic valve contacting with the magnetic steel generates magnetism repulsive to the magnetic steel, so as to be separated from the magnetic steel, the magnetic steel and the electromagnetic assembly 37 are removed from magnetic attraction, the driving unit 21 further drives the first screw 33 to rotate, so that the slider 34 slides along the first screw 33, and the second portion 342 clamps the shaft sleeve 342b to drive the transmission shaft 311 to move downwards, thereby driving the supporting structure 35 and the lens module 10, and the lens module 10 is driven by the second transmission component 32 to move downwards, when the lens component 11 of the lens module 10 is completely retracted in the accommodating space as shown in fig. 3, the driving unit 21 stops driving the first screw 33 to rotate, thereby completing the retraction and hiding of the lens module 10.

The invention has the beneficial effects that:

Furthermore, the electromagnetic valve is used as a magnetic element, so that the control module and the like can conveniently carry out integral control and matching on the drivingmodule 21 and the magnetic element, and the reciprocating and rotating motion of thelens module 10 can be integrally controlled, and the electromagnetic valve is simple and convenient to control and has higher reliability.

Further, the twoelectromagnetic assemblies 37 at the two ends of the supportingstructure 35 are used, so that the effect of balance fixation can be achieved, the reciprocating motion of thelens module 10 can be effectively prevented, and the effects of uniform force and high reliability are achieved.

Further, thefirst screw 33, thetransmission shaft 311 and theslider 34 are used for driving thelens module 10 to reciprocate, and thefirst screw 33, theslider 34 and thesecond screw 321 are used for driving thelens module 10 to rotate, so that the overall structure is simple, the realization is convenient, and the practicability is high.

Further, thesecond transmission assembly 32 further uses thefirst gear 322 and thesecond gear 13 to perform further transmission control on the rotation movement, so as to reduce the structural change of thelens module 10 itself, and facilitate the routing arrangement in the extension shaft thereof.

Preferably, in this embodiment, the mobile terminal 4 is a smart phone, and it can be understood that the mobile terminal 4 may also be a tablet computer or other mobile terminals with a camera function. Specifically, the mobile terminal 4 includes ahousing 41 and a lens lifting androtating device 1 that can be accommodated in theaccommodating space 413 of thehousing 41 and can at least partially extend out of theaccommodating space 413. Thehousing 41 includes aframe 411, a cover plate 412 (such as a front cover plate and a back cover plate) covering theframe 411 and enclosing anaccommodation space 413 together, and the lens lifting androtating device 1 as described above disposed in theaccommodation space 413, wherein theframe 411 has a throughopening 43 penetrating therethrough, thelens module 10 is disposed opposite to the throughopening 43, thelens assembly 11 of thelens module 10 can be driven by the drivingmodule 20 and thetransmission module 30 to extend out of theaccommodation space 413 and retract into theaccommodation space 413 through the throughopening 43, and after thelens assembly 11 of thelens module 10 completely extends out of theaccommodation space 413, thelens assembly 11 of thelens module 10 can rotate relative to the supportingstructure 35 and thehousing 41 of the terminal 4, so as to enable thelens assembly 11 of thelens module 10 to rotate and extend.

Of course, besides the above implementation methods, a mechanical and/or other structure capable of implementing the telescopic rotation function may be selected, and the lens lifting androtating device 1 is not limited to the above structure, and may be adjusted according to actual structural requirements.

It can be understood that, as shown in fig. 3, when thelens module 10 is retracted into theaccommodating space 413, the top end of thelens module 10 and the throughhole 43 are located on the same plane, so that thelens module 10 forms a package for the throughhole 43 and is hidden in theaccommodating space 413, and the mobile terminal 4 has an integral whole structure and better appearance and aesthetic feeling.

The working principle of the mobile terminal according to the embodiment of the present invention is further described below with reference to fig. 3 to fig. 6: as shown in fig. 3, when thelens module 10 is in the retracted state without being pushed out of thehousing 41, themotor 211 in thedriving module 20 is not operated, thesecond portion 342 of theslider 34 holds thesleeve 342b and makes the firstelastic element 312 in the extended state, so as to apply a pulling force to the supportingstructure 35, and meanwhile, thefirst portion 341 of theslider 34 is further connected to thelens module 10 through thesecond transmission assembly 32, so that the supportingstructure 35 and thelens module 10 above the supportingstructure 35 are in the retracted state retracted in theaccommodating space 413 of the mobile terminal 4. When a user needs to use the lens lifting and rotating device 1 (such as a front camera) and needs to push thelens module 10 out of the housing, the mobile terminal 4 receives the control command and sends an execution command to themobile driving module 20, themotor 211 of the drivingunit 21 rotates, and drives thefirst screw 33 to rotate, since thefirst screw 33 is connected to the slidingblock 34 through the first threadedhole 341a, and the position of thefirst screw 33 is maintained, the slidingblock 34 can move along thefirst screw 33 to the side where thelens module 10 is located, and further, thesecond portion 342 of the slidingblock 34 holds thesleeve 342b and gradually changes the firstelastic element 312 into a compressed state to push the supportingstructure 35 and thelens module 10 above it, meanwhile, thefirst portion 341 of theslider 34 pushes thelens module 10 through thesecond transmission assembly 32, so that thelens module 10 gradually extends out of theaccommodating space 413 of thehousing 41 of the mobile terminal 4. As shown in fig. 4, when thelens assembly 11 of thelens module 10 completely extends out of theaccommodating space 413, thelens assembly 11 can be used as a front camera, and can further perform shooting, and meanwhile, both ends of the supportingstructure 35 also abut against thehousing 41 of the terminal 4, specifically, theelectromagnetic assembly 37 of the supportingstructure 34 is attracted to the magnetic steel inside thehousing 41, so as to fix the position of the supportingstructure 35, and thelens module 10 can also maintain the extended state. When theelectromagnetic assembly 37 is an electromagnetic valve, the electromagnetic valve can be electrified through signal control, so that one end of the electromagnetic valve, which is in contact with the magnetic steel, generates magnetism which is attracted with the magnetic steel, and the magnetic steel and theelectromagnetic assembly 37 are attracted and fixed.

Further, on the basis of the extended state shown in fig. 4, when thelens module 10 needs to rotate in one direction (for example, to the right), the drivingunit 21 further drives thefirst screw 33 to rotate, so that the slidingblock 34 slides (for example, slides downwards) along thefirst screw 33, at this time, since the positions of the supportingstructure 35 and thetransmission shaft 311 connected to the supportingstructure 35 are fixed by the two magnetic valves, the movement of the slidingblock 34 drives thesecond screw 321 to rotate, and further drives thelens module 11 to rotate (for example, to the right) through thefirst gear 322 and thesecond gear 13, so as to realize the rotation of thelens module 11, and further thelens module 10 reaches the first rotation state shown in fig. 5, and when the proper shooting angle is reached, the drivingunit 21 can be controlled to stop rotating, so that thelens module 11 maintains the proper shooting angle for shooting.

Similarly, on the basis of the extended state shown in fig. 4, when thelens module 10 needs to rotate in one direction (for example, on the left), the drivingunit 21 further drives thefirst screw 33 to rotate, so that theslider 34 slides (for example, upwards slides) along thefirst screw 33, at this time, since the positions of the supportingstructure 35 and thetransmission shaft 311 connected to the supportingstructure 35 are fixed by the two magnetic valves, the movement of theslider 34 will drive thesecond screw 321 to rotate, and further drive thelens module 11 to rotate (for example, rotate towards the left) through thefirst gear 322 and thesecond gear 13, so as to realize the rotation of thelens module 11, and further thelens module 10 reaches the second rotation state shown in fig. 6, and when the proper shooting angle is reached, the drivingunit 21 can be controlled to stop rotating, so that thelens module 11 maintains the proper shooting angle for shooting. Specifically, in the present embodiment, thelens assembly 11 of thelens module 10 can rotate by 180 degrees relative to the angle shown in fig. 4.

Furthermore, when the lens module 10 is taken or the lens module 10 is not needed to be used and the lens module 10 extending out of the accommodating space 413 needs to be retracted, the driving unit 21 further drives the first screw 33 to rotate, so that the slider 34 slides along the first screw 33, the lens assembly 11 of the lens module 10 shown in fig. 5 or fig. 6 is firstly rotated to the extending state shown in fig. 4, then the electromagnetic valve is controlled by a signal to pass through a reverse current, the magnetic pole is reversed, the end of the electromagnetic valve contacting with the magnetic steel generates magnetism repelling with the magnetic steel, so as to be separated from the magnetic steel, the magnetic steel and the electromagnetic assembly 37 are released from magnetic attraction, the driving unit 21 further drives the first screw 33 to rotate, so that the slider 34 slides along the first screw 33, and the shaft sleeve b is clamped by the second portion 342 to drive the transmission shaft 311 to move downwards, thereby driving the supporting structure 35 and the lens module 10, and the lens module 10 is driven by the second transmission assembly 32 to move downwards, when the lens assembly 11 of the lens module 10 is fully retracted in the accommodating space 413 as shown in fig. 3, the driving unit 21 stops driving the first screw 33 to rotate, thereby completing the retraction and hiding of the lens module 10.

In summary, when the user needs to use the lens lifting and rotating device 1, the motor 211 works to push the lens module 10 out of the housing, and after the lens module is pushed to a predetermined position, the solenoid valve is opened to fix the supporting structure 35, so that the user can normally use the shooting function (such as the front camera function) of the mobile terminal; further, when a user needs to rotate the shooting angle of the lens lifting and rotating device 1, the mobile terminal receives the control instruction and sends an execution instruction, the motor 211 further works to drive the whole lens module 10 to rotate (including left rotation and right rotation), and after the lens module is rotated to a proper angle, the motor 211 can be controlled to stop working, so that the lens module 10 stops moving, shooting can be performed at a proper angle at the moment, the use by the user is facilitated, and meanwhile, the experience effect is also improved; when the lens module 10 is not needed to be used, the motor 211 works, the lens module 10 is rotated to the extended state shown in fig. 4, the motor 211 further works, and the lens module 10 is accommodated in the housing 41, so that the lens module 10 is prevented from being damaged by external force factors, the reliability of the mobile terminal 4 is improved, and meanwhile, the appearance of the mobile terminal 4 is more attractive.

The mobile terminal 4 of the present invention has the following application scenarios: during normal shooting, themotor 211 drives thelens module 10 to move up to the shooting position; when the 360-degree panoramic shooting is performed, themotor 211 drives thelens module 10 to rotate, and the OIS camera can compensate the shake of the hand and thelens module 10 in the rotating process; when shooting in the front, themotor 211 drives thelens module 10 to rotate rapidly; when the moving object is dynamically focused and tracked, the two cameras can analyze the angles of the moving object and the cameras in real time, and themotor 211 acts to drive the cameras to rotate and compensate, so that the real-time focusing of the moving object is realized; shooting at any angle,control motor 211 is rotatory to specific angle, also can carry out the shooting of 360 arbitrary angles in the scope when just to the screen, does not need the human body to rotate, and is more convenient.

While the foregoing is directed to embodiments of the present invention, it will be understood by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
