It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 6, an embodiment of the present application discloses an electronic device, which includes a base 100, a first driving mechanism 200, a second driving mechanism 300, and a lens 400.

The base 100, the first driving mechanism 200, the second driving mechanism 300, and the lens 400 are main components of the camera module. The first driving mechanism 200 and the second driving mechanism 300 are both used for driving the lens 400, so as to make the lens 400 perform different motions, and the lens 400 according to the embodiment of the present application is a lens having a zoom function, such as an AF or OIS lens. Specifically, the first driving mechanism 200 is disposed on the base 100, the lens 400 is disposed on the first driving mechanism 200, and the first driving mechanism 200 can drive the lens 400 to move between a first position and a second position along the optical axis direction of the lens 400, so as to implement the zooming function.

The optical axis direction of the lens 400 is also the axial direction of the lens 400. In the case of the first position, the distance of the lens 400 from the base 100 is a first distance. In the case of the second position, the distance of the lens 400 from the base 100 is a second distance. The second distance is less than the first distance. That is, the lens 400 is in a short focus state with the first position, and the lens 400 is in a long focus state with the second position. In this application embodiment, under the condition that camera lens 400 is in the short focal state, the focus is first focus, under the condition that camera lens 400 is in the long focal state, the focus is the second focus, and first focus is less than the second focus, and this application embodiment does not restrict the specific numerical value of first focus and second focus.

The second driving mechanism 300 is connected to the lens 400, thereby enabling the lens 400 to rotate. When the lens 400 is in the second position, in which the lens 400 is in the telephoto state, the second driving mechanism 300 drives the lens 400 to be rotatable around the optical axis between the first angle and the second angle.

The camera module disclosed in the embodiment of the present application may further include a first limiting portion 1100 and a second limiting portion 1000. The first position-limiting portion 1100 moves relative to the lens 400, and the second position-limiting portion 1000 is fixed relative to the lens 400. When the lens 400 is at the first angle, the first position-limiting portion 1100 and the second position-limiting portion 1000 are in position-limiting engagement in the direction of the lens 400, and the second position-limiting portion 1000 cannot move in the direction of the lens 400, and since the second position-limiting portion 1000 and the lens 400 are relatively fixed, the lens 400 cannot move in the direction of the lens 400, in this case, the lens 400 cannot move in the direction of decreasing focal length, and the lens 400 is a fixed-focus lens.

In the case where the lens 400 is at the second angle, the first stopper 1100 and the second stopper 1000 are engaged in a retreating manner, and in this case, the first stopper 1100 releases the stopper of the second stopper 1000 in the direction of the lens 400, so that the second stopper 1000 can move together with the lens 400 in the direction of the lens 400, and in this case, the lens 400 can move in the direction in which the focal length becomes smaller, thereby achieving zooming. In this case, the first driving mechanism 200 may drive the lens 400 to move to the first position, thereby switching to the short focus state.

The camera module disclosed in the embodiment of the application can be assembled in the electronic equipment, and particularly can be arranged below a display screen 900 of the electronic equipment, and the display screen 900 is provided with a light-transmitting area opposite to the lens 400 of the camera module, so that the lens 400 can view a view. The first driving mechanism 200 drives the lens 400 to move to the second position far from the display screen 900, and the second driving mechanism 300 can rotate the lens 400 located at the second position to the first angle, so that the lens 400 can form a fixed focus lens through the limit fit between the first limit portion 1100 and the second limit portion 1000, that is, the lens 400 is kept at the second position far from the display screen 900. Of course, in the process of zooming, the second driving mechanism 300 drives the lens 400 to rotate to the second angle, so that the limit fit between the first limit portion 1100 and the second limit portion 1000 can be released, in this case, the lens 400 is converted into a zoom lens, and can be switched between the first position and the second position.

Since the lens 400 can be restricted from moving to the first position in the second position, the distance between the lens 400 and the display screen 900 in the second position is designed to be a safety gap. Under the condition that electronic equipment takes place to fall or collide with, first actuating mechanism 200 and second actuating mechanism 300 drive camera lens 400 are in the second position to rotate to first angle, thereby avoid the damage of module of making a video recording to display screen 900.

The camera module disclosed in the embodiment of the application improves the structure of the camera module in the related art, so that the lens 400 can be switched between the first position and the second position, and under the condition that the lens 400 is at the second position and the first angle, the distance between the lens 400 and the display screen 900 of the electronic device is large and can be limited, and therefore the distance between the lens 400 and the display screen 900 at the second position can be designed into a safety gap. When the lens 400 is located at the second position, the lens 400 can rotate to the first angle and is limited by the cooperation between the first limiting portion 1100 and the second limiting portion 1000, so that the lens 400 cannot move towards the direction close to the display screen 900, and the lens 400 can be prevented from damaging the display screen 900.

Compared with the prior art that the gap between the lens 400 and the display screen 900 needs to be designed as the safety gap when the lens is in the short focus state, the embodiment of the present application undoubtedly enables the gap between the camera module and the display screen 900 when the camera module is in the long focus state to be designed as the safety gap, so that the camera module is closer to the display screen 900, and in the case that the shooting angle of view of the camera module is set, because the camera module is closer to the display screen 900, the size of the light-transmitting area formed on the display screen 900 is smaller, so that the screen occupation ratio of the electronic device can be increased, and simultaneously the appearance performance of the electronic device can be improved, so that the user experience of the electronic device can be improved, and the product competitiveness of the electronic device can be increased, in addition, the embodiment of the present application adopts the zoom lens, so that the zoom lens can be changed into the fixed focus lens under the condition of the safety gap under the dangerous conditions such as the falling process and the like, the lens is fixed, so that the lens is prevented from damaging the display screen, and the safety performance of the electronic equipment can be improved.

In the embodiment of the present application, the first driving mechanism 200 may drive the lens 400 to move between the first position and the second position in the optical axis direction of the lens 400. Similarly, the first driving mechanism 200 may be of various types, and the first driving mechanism 200 may be a currently-used focus mechanism-voice coil motor. Of course, the first driving mechanism 200 may also be a telescopic mechanism (e.g., a hydraulic telescopic mechanism or a pneumatic telescopic mechanism), and the telescopic mechanism may be connected to the lens 400 to drive the lens 400 to move.

Of course, the telescopic mechanism may be separated from or rotationally engaged with the lens 400 at the second position, so that the second driving mechanism 300 can drive the lens 400 to rotate, i.e. the driving of the second driving mechanism 300 to rotate the lens 400 is not affected. For example, the telescopic mechanism may be provided with an electromagnetic structure, and the electromagnetic structure generates magnetism in a power-on state to further adsorb the lens 400, so as to realize power connection between the telescopic mechanism and the lens 400, and when the electromagnetic structure is powered off, the magnetism disappears, and the telescopic mechanism is separated from the electromagnetic structure, so as to avoid influencing subsequent rotation of the lens 400.

As described above, the second driving mechanism 300 is used to drive the lens 400 to rotate between the first angle and the second angle around the optical axis. The second driving mechanism 300 may be of various types, for example, the second driving mechanism 300 may include a micro driving motor and a gear transmission mechanism, specifically, a gear ring may be disposed on the periphery of the lens 400, and the driving motor may be connected to the gear ring through the gear transmission mechanism, so that the driving motor drives the gear ring to drive the lens 400 to rotate through the gear transmission mechanism. Of course, the length of the meshing teeth of the ring gear may be designed to be long, so that the ring gear can be always kept in a state of meshing with the gear transmission mechanism during the movement of the lens 400 in the optical axis direction. Of course, the gear transmission mechanism may be provided with a clutch device, and the engagement and disengagement between the gear transmission mechanism and the ring gear are mediated by the clutch device, so that after the gear transmission mechanism is disengaged from the ring gear, the movement of the lens 400 in the optical axis direction is not interfered by the second driving mechanism 300.

Of course, the second driving mechanism 300 may be of other types, for example, in an alternative, the second driving mechanism 300 may include a stator coil 310 and a rotor coil 320, the rotor coil 320 is connected to the lens 400, the stator coil 310 is connected to the base 100, and the lens 400 may rotate between the first angle and the second angle with the rotor coil 320 when the stator coil 310 and the rotor coil 320 are energized. That is, the rotor coil 320 can rotate in the magnetic field generated by the stator coil 310 after being energized, and further drives the lens 400 to rotate together, and finally, the lens 400 is driven to rotate. In this case, the magnetic field force between the rotor coil 320 and the stator coil 310 is a driving force, and the magnetic field force is a non-contact force, so that abrasion caused by direct contact between the second driving mechanism 300 and the lens 400 can be reduced. Meanwhile, the coverage area of the magnetic field generated by the stator coil 310 after being electrified is large, which is beneficial to realizing the stress when the rotor coil 320 is electrified, so the driving matching between the stator coil 310 and the rotor coil 320 has low requirement on the assembly precision, and is beneficial to the assembly of the second driving mechanism 300.

Specifically, the end of the base 100 facing the lens 400 may be provided with a recess 130, and the stator coil 310 may be disposed in the recess 130, so as to fix the stator coil 310 on the base 100. Under this condition, base 100 can open up special space and hold stator coil 310, and then realizes stator coil 310 and install, is favorable to improving the compactness of assembly, is favorable to reducing the complete machine size of camera module group simultaneously.

In a further embodiment, the rotor coil 320 and the stator coil 310 may be disposed opposite to each other. This arrangement is more advantageous in applying a magnetic force to the rotor coil 320, and further, in improving the driving efficiency.

As described above, in a specific driving process, the stator coil 310 drives the rotor coil 320 to rotate, that is, the rotor coil 320 is forced to move in the magnetic field formed by the stator coil 310, and in order to more efficiently apply the driving force to the rotor coil 320, the rotor coil 320 may be covered on the stator coil 310, in which case, the area of the rotor coil 320 in the magnetic field is larger, which is more beneficial to enable the rotor coil 320 to cover a region with larger magnetic field strength, so that the rotor coil 320 is subjected to larger magnetic field force, and thus the driving performance is improved.

In the embodiment of the present application, the first driving mechanism 200 may have a plurality of structures, and in an alternative scheme, the first driving mechanism 200 may include a driving mechanism housing 210 and a holder 220, the holder 220 is fixedly connected to the lens 400, the holder 220 and the driving mechanism housing 210 are movably engaged in the optical axis direction of the lens 400, and in a case that the first driving mechanism 200 is a voice coil motor, when the first driving mechanism 200 works, the holder 220 is driven to drive the lens 400 to move between the first position and the second position.

Specifically, the holder 220 may be provided with a second limiting portion 1000, the driving mechanism housing 210 may be provided with a first limiting portion 1100, the second driving mechanism 300 may drive the holder 220 to drive the lens 400 to rotate, and the second limiting portion 1000 may rotate along with the holder 220. In this case, the engagement between the first position-limiting portion 1100 and the second position-limiting portion 1000 can limit the holder 220 from being held at the second position, and finally limit the lens 400 to be a fixed focus lens. This structure can avoid the second position-limiting portion 1000 being disposed on the lens 400, and further can avoid the adverse effect on the lens 400 caused by the design of the second position-limiting portion 1000.

In a further technical solution, the outer edge of the end of the base 100 may be provided with a sinking platform 110, the sinking platform 110 may be used for carrying other components, and the driving mechanism housing 210 may be sleeved on the end of the base 100 and supported on the sinking platform 110. In this case, since the height of the sinking platform 110 is lower than the height of the other regions of the end of the base 100, sinking of the driving mechanism housing 210 is facilitated, thereby facilitating reduction of the stacking height of the camera module.

In the embodiment of the present application, the first position-limiting portion 1100 and the second position-limiting portion 1000 may have various structures. In an alternative scheme, the first limiting portion 1100 may be at least two first limiting protrusions disposed on an inner wall of the driving mechanism housing 210, the at least two first limiting protrusions are disposed at intervals around the lens 400, the second limiting portion 1000 is at least two second limiting protrusions disposed on the holder 220, and the at least two second limiting protrusions are disposed at intervals around the lens 400. At least two first spacing archs and two at least second spacing archs set up around camera lens 400 interval, consequently are in the second position and are in under the condition of first angle at camera lens 400, and two at least first spacing archs and two at least second spacing protruding equal spacing cooperation can implement spacingly to camera lens 400 more balancedly undoubtedly, are favorable to making spacing cooperation more stable.

In a further technical solution, under the condition that the lens 400 is at the second angle, the first limiting protrusion and the second limiting protrusion are in guiding fit in the extending direction of the optical axis, and at this time, the first limiting portion 1100 can also play a guiding role, so that the stability of the lens 400 moving between the first position and the second position is improved.
