Referring to fig. 4, in the present embodiment, the locking assembly 57 includes a mounting member 571, a locking member 573, and a deformation driving member 575.

A mounting member 571 is connected to the bracket 52 and fixed to the bottom wall 121 of the housing 10, and the mounting member 571 is used for mounting the locking member 573 and for guiding the moving direction of the locking member 573. In the present embodiment, the mounting member 571 is a substantially guide rail structure, which is substantially perpendicular to the moving direction of the camera module 30. The mounting member 571 includes a first sidewall 5711 and a second sidewall 5713 disposed opposite to each other, wherein an accommodating space 5715 is formed between the first sidewall 5711 and the second sidewall 5713, and the accommodating space 5715 is used for accommodating the locking member 573. Further, the mounting member 571 further includes an end wall 5717, and the end wall 5717 is connected between the first side wall 5711 and the second side wall 5713 and is located on a side of the accommodating space 5715 away from the bracket 52. The end wall 5717 is provided with a containing hole 5719, and the containing hole 5719 penetrates through the end wall 5717 and is communicated with the containing space 5715. The receiving hole 5719 serves to reserve a sufficient space for the movement of the locking member 573.

The locking member 573 is slidably received in the receiving space 5715, and the mounting member 571 is used to limit the moving direction of the locking member 573. In the present embodiment, the locking member 573 is a substantially rod-shaped structure, which is substantially perpendicular to the moving direction of the camera module 30, and is movably inserted through the mounting member 517. One end of the locking member 573 extends toward the camera module 30 and is movably held by the camera module 30.

Specifically, the locking piece 573 includes a connecting portion 5731 and a catch 5733. The connection portion 5731 is movably disposed in the receiving space 5715 and the receiving hole 5719 and is used for connecting the deformation driving member 575.

The catch 5733 is connected to an end of the connecting portion 5731 near the camera module 30, and the catch 5733 is used for catching the camera module 30. Correspondingly, the bracket 52 is provided with a limit slot 5201 (for example, the fixing frame 521 is provided with a limit slot 5201, see fig. 3), the holding member 32 of the camera module 30 is provided with a engaging portion 3213, the engaging portion 3213 is provided on one side of the holding member 32 facing the limit slot 5201, and the engaging portion 5733 is movably disposed through the limit slot 5201 and is engaged with the engaging portion 3213 to limit the camera module 30 in the housing 10. When the catch 5733 is disengaged from the catch 3213, the camera module 30 is driven by the driving assembly 54 to protrude out of the housing 10. Further, a side of the catch 5733 toward the through hole 1231 is provided with a guide bevel 5735, and the guide bevel 5735 exhibits a chamfered structure so that the catch 5733 is easily snap-fitted with the catch 3213.

Further, the locking piece 573 further includes a spacer 5737 connected to the connecting portion 5731. In the present embodiment, the spacer 5737 is formed substantially in a flange shape, and is provided at a substantially middle position of the connecting portion 5731.

The deformation driving member 575 is connected to the connection portion 5731 and is located on a side of the spacing portion 5737 facing the camera module 30.

In the embodiment shown in fig. 4, the deformation driving member 575 is an elastic member, and one end of the deformation driving member 575 is connected to the spacing portion 5737 and the other end is connected to the fixing member 521 of the bracket 52. The deformable drive member 575 is made of a Shape Memory material, such as Shape Memory Polymers (SMP) or Shape Memory Alloys (SMA). The shape memory polymer is also called shape memory polymer, and refers to a polymer material which can restore the initial shape of a product with the initial shape through the stimulation of external conditions (such as heat, electricity, light, chemical induction and the like) after the initial condition is changed and the product is fixed under certain conditions. Shape Memory alloys are materials composed of two or more metal elements that have a Shape Memory Effect (SME) through thermoelastic and martensitic transformation and inversion thereof.

The deformation driving member 575 may be driven by any one of optical driving deformation, thermal driving deformation, electrical driving deformation, and magnetic driving deformation. Further, in the present embodiment, the deformation driving member 575 is a spring made of a shape memory alloy, which is deformed by an electric drive. The deformation driving member 575 is electrically connected to an internal circuit of the electronic device 100, and electric energy is converted into heat energy due to a thermal effect of the current, and the temperature of the deformation driving member 575 can be controlled by controlling the magnitude of the current flowing through the deformation driving member 575, so as to induce a shape memory effect of the deformation driving member 575 and control a deformation amount (such as an elongation or a shortening) of the deformation driving member 575, so that the deformation driving member 575 can push the locking member 573 to be away from the camera module 30, or pull the locking member 573 to be close to the camera module 30 and to be clamped with the camera module 30.

In this embodiment, the deformation driving member 575 is a coil spring, which is sleeved on the locking member 573. It is understood that in other embodiments, the deformable actuation member 575 may be other resilient structures, such as a spring, a resilient sleeve, etc. Alternatively, the deformation driving member 575 is not limited to the elastic body, for example, the deformation driving member 575 may be a bar-shaped structure, a sheet-shaped structure, a plate-shaped structure, a cylinder-shaped structure, or even a block-shaped structure made of a shape memory material, so that the deformation driving member 575 can deform at a predetermined temperature, or/and provide a pushing force to the locking member 573 away from the camera module 30 when the temperature of the locking member 573 rises, so as to release the locking member 573 from the clamping state of the camera module 30.

It is understood that, in some embodiments, the deformation driving member 575 may directly abut against the spacing portion 5737 or/and the fixing member 521, and after the camera module 30 is ejected by the deformation driving member 575, the current flowing through the deformation driving member 575 may be timely reduced or interrupted, the temperature of the deformation driving member 575 is reduced, so that the deformation driving member 575 is restored to the initial state without pulling the locking member 573 to reset, and at this time, the locking assembly 57 may include a reset elastic member 577, and the reset elastic member 577 pushes the locking member 5733 to approach the camera module 30 and to be clamped with the camera module 30.

The return spring 577 may be provided on the connecting portion 5731 on a side of the spacer portion 5737 facing away from the deformation driving member 575. In the present embodiment, the elastic return member 577 is a coil spring, which is sleeved on the connecting portion 5731 and elastically pressed between the spacing portion 5737 and the end wall 5717. The return spring 577 is used to provide a pushing force to the locking member 573 toward the camera module 30, so that the locking member 573 is caught by the camera module 30. In the present embodiment, the elastic return element 577 is a coil spring, and it is understood that in other embodiments, the elastic return element 577 may also be other elastic structures, such as a spring sheet, an elastic sleeve, and so on.

Further, in the normal temperature state, the locking member 573 is held by the camera module 30, and the urging force of the return elastic member 577 against the spacing portion 5737 is equal to the urging force of the deformation driving member 575 against the spacing portion 5737. When the deformation driving member 575 is powered on, the temperature thereof rises, and the deformation driving member 575 extends, so that the pushing force thereof on the spacing portion 573 increases, so that the locking member 573 gradually moves away from the camera module 30, and finally disengages from the camera module 30, so that the camera module 30 is pushed by the driving assembly 54 to extend out of the housing 10.

Further, in some embodiments, the drive mechanism 50 may further include a temperature sensor 59, the temperature sensor 59 being disposed adjacent to the deformation drive member 575 and configured to detect a temperature of the deformation drive member 575. In the present embodiment, the temperature sensor 59 is connected to the deformation driving member 575 so as to detect the temperature of the deformation driving member 575 more accurately. When the temperature sensor 59 detects that the temperature of the deformation driving member 575 reaches a preset temperature, the control center of the electronic device 100 controls the current flowing through the deformation driving member 575 to be reduced or powered off, thereby controlling the deformation of the deformation driving member 575. It is understood that in other embodiments, the temperature sensor 59 can be coupled to the mounting member 571 and positioned adjacent the deformation actuator 575.

Referring to fig. 5, it is to be understood that, in some embodiments, the return elastic member 577 may be omitted and the deformation driving member 575 may be disposed between the locking member 573 and the fixing member 521 and connected to the spacing portion 5737 of the locking member 573. When the deformation driving member 575 is powered on, the temperature thereof rises, the deformation driving member 575 extends and pushes the locking member 573 to move away from the camera module 30, and the locking member 573 is finally disengaged from the camera module 30, so that the camera module 30 is pushed by the driving member 54 to extend out of the housing 10. When the camera module 30 is ejected, the current of the deformation driving member 575 is cut off, and the deformation driving member 575 recovers the deformation (shortens), and pulls the locking member 573 toward the fixing member 521. In this case, the deformation driving member 575 may be used as a return spring of the locking member 573, and the structure of the locking assembly 57 can be simplified.

Referring to fig. 6, in other embodiments, the deformation driving member 575 may be magnetically driven to deform, and may include magnetically conductive particles, such as magnetically conductive metal particles, or magnetic nanoparticles. In some embodiments, the deformation driving member 575 may be made of a shape memory polymer containing magnetic nanoparticles or a shape memory alloy.

Further, the locking assembly 57 further includes a field coil 579 (shown in cross-section), the field coil 579 being disposed around the outer periphery of the mounting member 571 and corresponding to the installation position of the deformation actuating member 575. In this embodiment, the installation part 571 serves as an iron core for bearing the excitation coil 579, the installation part 571 and the excitation coil 579 together form an electromagnet mechanism, the excitation coil 579 generates a high-frequency alternating magnetic field by controlling the current of the excitation coil 579, so that the movement direction of the magnetic particles in the deformation driving member 575 is induced to generate high-frequency change, and the magnetic field energy is converted into heat energy by the friction force generated between the magnetic particles of the deformation driving member 575 and the base material of the deformation driving member 575, so that the deformation driving member 575 is deformed. In this embodiment, when the camera module 30 is accommodated in the housing 10, the deformation driving member 575 is at a normal temperature, and when the camera module 30 needs to be extended out of the housing 10, the deformation driving member 575 is induced by the magnetic field of the excitation coil 579 to generate tensile deformation by controlling the current of the excitation coil 579, and the deformation driving member 575 provides a pushing force to the locking member 573, which is away from the camera module 30, so that the locking member 573 is disengaged from the camera module 30 and the camera module 30 is extended out of the housing under the pushing of the driving assembly 54.

It is understood that in other embodiments, the locking assembly 57 can be provided with an electromagnet to generate the magnetic field, and the electromagnet can be provided adjacent to the deformation driving member 575, for example, the electromagnet can be provided above, below, or around the deformation driving member 575, or around the mounting member 571, so that the deformation driving member 575 can be located in the magnetic field generated by the electromagnet.

For another example, referring to fig. 7, in some embodiments, the locking assembly 57 further includes an electromagnet 60, in which case, the elastic restoring member 577 can be omitted, and the deformation driving member 575 is disposed on a side of the spacing portion 5737 facing away from the camera module 30, and the deformation driving member 575 is connected between the spacing portion 5737 and the end wall 5717 of the mounting member 571. The electromagnet 60 is disposed at an end of the mounting member 571 away from the camera module 30, the electromagnet 60 includes an iron core 62 and a coil 64 wound around the iron core 62, and the coil 64 is electrically connected to an internal circuit of the electronic device 100. By controlling the magnitude and direction of the current flowing through coil 64, the direction of the magnetic field generated by electromagnet 60 can be controlled. In this embodiment, when the camera module 30 is accommodated in the housing 10, the deformation driving member 575 is at a normal temperature, and when the camera module 30 needs to be extended out of the housing 10, the deformation driving member 575 generates compression deformation under the induction of the magnetic field of the coil 64 by controlling the current of the coil 64, and the deformation driving member 575 provides a pulling force far away from the camera module 30 to the locking member 573, so that the locking member 573 is disengaged from the camera module 30, and the camera module 30 is extended out of the housing under the pushing of the driving component 54. When the current of the coil 64 is cut off after the camera module 30 is ejected, the deformation driving member 575 is deformed (extended) and pushes the locking member 573 toward the fixing member 521. In this case, the deformation driving member 575 may be used as a return spring of the locking member 573, and the structure of the locking assembly 57 can be simplified.

Compared with the prior art, the retractable structure of the camera module 30 of the electronic device 100 allows the camera module 30 to be extended when the camera module 30 is used, and allows the camera module 30 to be retracted into the housing 10 when the camera module 30 is not used, so that holes for accommodating or exposing the camera module 30 can be prevented from being formed in the front surface or/and the back surface of the housing 10 of the electronic device 100, and the electronic device 100 is more attractive while the housing 10 maintains good appearance integrity. In addition, the camera module 30 can be extended and retracted relative to the housing 10 instead of being directly disposed on the front surface of the housing 10, which is beneficial to vacating more installation space for the display screen 101, so that the electronic device 100 has a higher screen occupation ratio on the premise of unchanging the external size, which is beneficial to realizing full screen display of the electronic device 100. Further, the deformation driving member 575 is designed as a shape memory deformation member, and the deformation is controlled by controlling the temperature of the deformation driving member 575, so as to control the clamping state of the locking member 573 and the camera module 30, so as to allow the driving component 54 to push the camera module 30 out of the housing 10, thereby simplifying the structure of the driving mechanism 50, effectively improving the compactness of the spatial layout of the components, and reducing the spatial layout of the pop-up camera module 30.

Further, in some embodiments, the camera module 30 may include any one or more of a front camera, a rear camera, or a flash. Further, in some embodiments, other functional components may be disposed on the camera module 30, for example, any one or more of the receiver assembly, the sensor assembly, and the flashlight assembly may be disposed on the camera module 30, and in this case, the holder 32, the lens assembly 34 and any one or more of the receiver assembly, the sensor assembly, and the flashlight assembly form a functional module, and the functional module is driven by the driving mechanism 50 to extend out of the housing 19. In other words, the functional module may include any one or more functional components such as a front camera, a rear camera, a flash, a receiver, and a sensor, and the functional module is extended out of the housing 19 by the driving mechanism 50, and is retracted into the housing 10 when the functional module is not needed, so that a hole for accommodating or exposing the functional module can be avoided being formed in the front surface or/and the back surface of the housing 10 of the electronic device 100, and the electronic device 100 is more beautiful while the housing 10 maintains good appearance integrity.
