The screw 21 rotates in the reverse direction in the preset direction, the worm wheel 22 slides from the second end 212 to the first end 211 relative to the base 10, and the worm wheel 22 drives the sliding member 31 to contract relative to the base 10. The worm wheel 22 includes a screw-coupling end 221 and a click end 222 disposed opposite to the screw-coupling end 221. The engaging end 222 is located on one side of the screw 21.

In this embodiment, the elastic clip 23 applies an elastic clamping force to the hook 311, so that the elastic clip 23 is firmly connected to the hook 311, the turbine 22 drives the sliding module 20 to stretch and contract relative to the base 10, and the resistance received by the elastic clip 23 is smaller than the elastic clamping force applied to the hook 311, so that the turbine 22 can drive the sliding member 31 and the at least one functional device 32 to stretch and contract relative to the base 10. When the sliding module 20 is subjected to falling impact, impact or extrusion impact acting force which is greater than the elastic clamping force of the elastic buckle 23 on the hook 311, the elastic buckle 23 is separated from the hook 311, so that the sliding module 30 is disconnected from the driving mechanism 20, and the driving mechanism 20 and the sliding module 30 cannot be damaged due to rigid impact.

In this embodiment, the sliding member 31 includes a first sliding end 312 and a second sliding end 313 opposite to the first sliding end 312. The first sliding end 312 slides in the receiving cavity 11. The first sliding end 312 slides to the telescopic hole 12, and the second sliding end 313 slides out of the accommodating cavity 11 to drive the at least one functional device 32 to extend out relative to the base 10. The first sliding end 312 slides to a position far away from the telescopic hole 12, and the second sliding end 313 slides into the accommodating cavity 11 to drive the at least one functional device 32 to contract relative to the base 10.

The accommodating groove 313 accommodates the at least one functional device 32.

In the present embodiment, the hook 311 is disposed on the side of the slider 31 facing the screw 21. The hook 311 is partially overlapped with the elastic catch 23 in the sliding direction of the slider 31. The hook 311 is dislocated with the sliding member 31 relative to the elastic buckle 23, so that the hook 311 is separated from the elastic buckle 23, when the sliding member 31 is disconnected from the turbine 22, if the sliding member 31 is in an extended state relative to the base 10, and the second sliding end 313 of the sliding member 31 is subjected to a falling acting force, an impact acting force or an extrusion acting force, the sliding member 31 can be retracted relative to the base 10 to be contracted, the sliding member 31 and the at least one functional device 32 cannot be damaged by impact, the screw rod 21 and the turbine 22 cannot be damaged by impact, and the safety of the functional device 100 is ensured. When the hook 311 slides to a position facing the elastic buckle 23 along with the sliding member 31, the hook 311 engages with the elastic buckle 23, the worm wheel 22 and the sliding member 31 return to the original position, and the driving mechanism 20 can drive the sliding module 30 to extend and retract relative to the base 10.

In this embodiment, the at least one functional device 32 may be any one or more combinations of functional devices such as a camera module, an iris recognition module, a face recognition module, a flash lamp, a microphone, a receiver, a photoreceptor, a fingerprint module, and a key.

The at least one functional device 32 is hidden from view by the base 10 such that the user cannot view the at least one functional device 32, resulting in a compact appearance of the functional assembly 100. When the at least one functional device 32 slides along with the sliding member 31 to a state where the at least one functional device extends out of the base 10, the at least one functional device 32 is arranged side by side with the base 10, so that a user can use the functional assembly 100 conveniently, and the operation experience is improved.

Further, referring to fig. 6 and 7, the base 10 is provided with a first guide groove 13, the screw rod 21 is located in the first guide groove 13, the worm wheel 22 is slidably connected to the first guide groove 13, and the elastic buckle 23 is located outside the first guide groove 13.

In the present embodiment, the first guide groove 13 slidably guides the worm wheel 22, and prevents the worm wheel 22 from rotating with the screw 21, so that the worm wheel 22 can transmit a sliding torque to the slider 31. The first guide groove 13 is opened at the bottom of the accommodating cavity 11. The first guide groove 13 is located between the two ribs at the bottom of the accommodating cavity 11. The first guide groove 13 extends to the inner side wall of the accommodating cavity 11. The outer side wall of the bottom of the screw-threaded end 221 of the worm wheel 22 is in clearance fit with the inner side wall of the guide groove 13. The engaging end 222 is located outside the first guiding groove 13 to facilitate the engagement of the elastic buckle 23 with the hook 311. The first guide groove 13 has an opening facing the same direction as the housing chamber 11 to facilitate the installation of the worm wheel 22 into the first guide groove 13. The base 10 is provided with a first limiting block 14 at a position where the first guide groove 13 is far away from the telescopic hole 12, and the first limiting block 14 limits the turbine 22, so that the turbine 22 is prevented from being separated from the screw rod 21. When the sliding member 31 drives the at least one functional device 32 to retract to the base 10, the turbine 22 abuts against the first limiting block 14, so as to prevent the sliding member 21 from further sliding relative to the base 10, so as to stabilize the structure of the functional assembly 100.

Further, referring to fig. 8 and 9, the base 10 is provided with a second guide slot 15 parallel to the first guide slot 13, the sliding member 21 is slidably connected to the second guide slot 15, and the portion of the sliding member 31 exposed out of the second guide slot 15 is provided with the hook 311.

In the present embodiment, the second guide groove 15 is spaced apart from the first guide groove 13. The second guide groove 15 slidably guides the slider 31 so as to prevent the slider 31 from being displaced in the housing chamber 11 after being disconnected from the turbine 22. The second guide groove 15 is opened at the bottom of the accommodating cavity 11. The second guide slot 15 is located between two ribs at the bottom of the accommodating cavity 11. The second guide groove 15 extends to the telescopic hole 12. The bottom outer side wall of the sliding member 31 is in clearance fit with the inner side wall of the second guide groove 15. The second guide groove 15 has an opening facing the receiving cavity 11 to facilitate the fitting of the slider 31 into the second guide groove 15. The base 10 is provided with a second limiting block 16 at a position where the second guide groove 15 is far away from the telescopic hole 12, and the second limiting block 16 limits the sliding part 31, so that the sliding part 31 is prevented from being separated from the screw rod 21. When the sliding member 31 drives the at least one functional device 32 to retract to the base 10, the sliding member 31 abuts against the second limiting block 16, so as to prevent the sliding member 31 from further sliding relative to the base 10, and thus the structural stability of the functional assembly 100 is improved.

Further, referring to fig. 10 to 14, the elastic buckle 23 includes a first elastic sheet 231 and a second elastic sheet 232 fixed to the turbine 22, the first elastic sheet 231 and the second elastic sheet 232 are oppositely disposed in a direction parallel to the screw rod 21, the hook 311 is clamped between the first elastic sheet 231 and the second elastic sheet 232, and the hook 311 is engaged with the elastic buckle 23.

In this embodiment, the first elastic piece 231 and the second elastic piece 232 are both fixed to the engaging end 222 and extend in a direction substantially perpendicular to the lead screw 21. A gap exists between the first elastic sheet 231 and the second elastic sheet 232. The first elastic piece 231 is close to the telescopic hole 12 relative to the second elastic piece 232. The first elastic sheet 231 and the second elastic sheet 232 clamp the hook 311, the elastic buckle 23 is engaged with the hook 311, and the turbine 22 is connected with the sliding member 31 through the elastic buckle 23. As shown in the figure, when the screw rod 21 drives the worm wheel 22 to slide from the position close to the second end 212 to the position close to the first end 211 relative to the base 10, the first elastic piece 231 deforms towards the position away from the second elastic piece 232 so as to provide the hook 311 with an elastic force for sliding away from the telescopic hole 12, and the worm wheel 22 drives the sliding member 31 to contract relative to the base 10. When the screw rod 21 drives the worm wheel 22 to slide from the position close to the first end 211 to the position close to the second end 212 relative to the base 10, the second elastic piece 232 deforms to provide an elastic force for the hook 311 to slide towards the telescopic hole 12, and the worm wheel 22 drives the sliding piece 31 to extend out relative to the base 10. When the impact acting force of the sliding member 31 is greater than the elastic acting force of the second elastic sheet 232 on the hook 311, the second elastic sheet 232 is further deformed, so that the hook 311 is dislocated relative to the second elastic sheet 232, and the hook 311 is separated from the second elastic sheet 232 along with the impact acting force of the sliding member 31, that is, the sliding member 31 is separated from the turbine 22, thereby preventing the sliding module 30 and the driving mechanism 20 from being damaged by the rigid impact acting force. When the sliding member 31 retracts to a state of contracting relative to the base 10, the screw rod 21 drives the turbine 22 to slide towards the direction close to the sliding member 31, and under the interference force of the second limiting block 16 to the sliding member 31, the second elastic sheet 23 contacts the hook 311 and deforms towards the direction close to the first elastic sheet 231, so that the hook 311 slides into the space between the first elastic sheet 231 and the second elastic sheet 232 again, the elastic buckle 23 is engaged with the hook 311 again, and the screw rod 21 can drive the sliding member 31 to extend and contract relative to the base 10 again.

Further, referring to fig. 15, a first protrusion 233 facing the second elastic piece 232 is disposed at an end of the first elastic piece 231 away from the turbine 22, a second protrusion 234 facing the first elastic piece 231 is disposed at an end of the second elastic piece 232 away from the turbine 22, and the hook 311 has a first groove 313 and a second groove 314 respectively matching with the first protrusion 233 and the second protrusion 234.

In this embodiment, the first bump 233 and the second bump 234 are both hemispherical. The first groove 313 and the second groove 314 are both hemispherical grooves. When the hook 311 slides into the space between the first elastic sheet 231 and the second elastic sheet 232, the arc surfaces of the first protruding block 232 and the second protruding block 234 reduce the resistance to the hook 311, so that the hook 311 and the elastic buckle 23 can be conveniently jointed. The first protrusion 232 is matched with the first groove 313, and the second protrusion 234 is matched with the second groove 314, so that the structure of the hook 311, the first elastic piece 231 and the second elastic piece 232 is stable. The sliding damping force of the first protrusion 232 and the second protrusion 233 to the hook 311 is reduced, so that the hook 311 is conveniently separated from the elastic buckle 23 when the slider 31 receives an impact force.

Further, referring to fig. 16, the sliding member 311 is provided with a plurality of side-by-side hooks 311 in a direction parallel to the screw rod 21. The plurality of hooks 311 are arranged at equal intervals. When the sliding member 31 is acted by an impact force, the elastic buckle 23 is separated from one of the hooks 311 and can be engaged with the other hook 311, so that the sliding member 311 does not rigidly impact the base 10 under the impact force, and the sliding member 31 is buffered. The plurality of hooks 311 are distributed at a plurality of different positions of the sliding member 31, so that the sliding stroke of the sliding member 31 can be changed, and the telescopic position of the sliding member 31 relative to the base 10 can be adjusted.

Further, referring to fig. 17, the driving mechanism 20 further includes a motor 24 fixed to the base 10, and the motor 24 drives the screw rod 21 to rotate.

In this embodiment, the motor 24 is fixed to the bottom of the accommodating chamber 11. The motor 24 can drive the screw rod 21 to rotate in a preset direction, and can also drive the screw rod 21 to rotate in the reverse direction of the preset direction, so that the turbine 22 can be driven to drive the sliding part 31 to extend relative to the base 10, and the turbine 22 can be driven to drive the sliding part 31 to retract relative to the base 10. The motor 24 is fixed to the base 10, so that the driving mechanism 20 is structurally stable.

The housing cavity 11 is used for fixing an electronic device, which can be a battery, a mainboard, a central controller and the like. The display screen 40 covers the containing cavity 11. The at least one function device 32 may slide with the slider 31 to a state of being stacked or spread with the display screen 40. It can be understood that the at least one functional device 32 slides to the position overlapping with the display screen 40 along with the sliding member 31, the sliding member 31 is accommodated between the display screen 40 and the base 10, and the functional device 32 is covered by the display screen 40, so that the electronic device 100 is convenient for a user to carry, the display area and the screen area of the display screen 40 are improved, and the user experience is increased. The functional device 32 slides with the sliding member 31 to a position where the functional device is unfolded relative to the display screen 40, and the functional device 32 is exposed from one side of the display screen 40, so that a corresponding function is realized. The electronic device 200 may be a mobile phone, a tablet computer, a notebook computer, etc.

In this embodiment, the display screen 40 is a full screen. The display screen 40 has a rectangular plate shape. The display 40 has a first short side 41 and a second short side 42 arranged opposite to the first short side 41, and two oppositely arranged long sides 43 connected between the first short side 41 and the second short side 42. The first short side 41 is close to the slide 31. The display screen 40 is provided with an extremely narrow non-display area 44 near the first short side 41 and near the second short side 42, the non-display area 44 forms a narrow side of the display screen 40, and the non-display area 44 is only used for providing a driving cable for the display screen 40 so as to realize the display of the display screen 40. The display 40 also has a display area 45 connected to the non-display area 44. When the sliding member 31 slides the at least one functional device 32 into a position stacked with respect to the display screen 40, the display area 45 partially or completely covers the at least one functional device 32, so as to increase the occupation ratio of the display area 45 in the display screen 40. The Display 40 may be a Liquid Crystal Display (LCD) or an Organic Light-Emitting Display (OLED).

Referring to fig. 20, the present application further provides a control method of an electronic device, which is applied to the electronic device 200. The control method of the electronic device comprises the following steps:

101: the electronic device 100 receives the extension signal, and the electronic device 100 controls the driving mechanism 20 to drive the lead screw 21 to rotate along a first preset direction according to the extension signal, so as to drive the turbine 22 to slide along the first sliding direction relative to the base 10, and drive the sliding member 31 to extend relative to the base 10 by engaging the elastic buckle 23 with the hook 311.

In this embodiment, in step 101, after receiving the extension signal, the electronic device 100 detects whether an elastic threshold of the elastic buckle 23 meets a preset value.

If yes, the driving mechanism 20 drives the screw rod 21 to rotate along a first predetermined direction, so as to drive the turbine 22 to slide along a first sliding direction relative to the base 10, and drive the sliding member 31 to extend out relative to the base 10 by engaging the elastic buckle 23 with the hook 311.

If not, the electronic device 200 controls the driving mechanism 20 to drive the screw rod 21 to rotate in the first preset direction in the opposite direction, so as to drive the turbine 22 to slide in the first sliding direction in the opposite direction relative to the base 10.

It can be understood that the threshold value of the elastic force of the elastic buckle 23 is the magnitude of the elastic force of the elastic buckle 23. The magnitude of the elastic force of the elastic buckle 23 is detected by a pressure sensor. The preset value of the elasticity of the elastic buckle 23 is the magnitude of the elastic acting force applied to the hook 311 after the elastic buckle 23 is jointed with the hook 311. After the elastic buckle 23 is connected with the hook 311, the elastic buckle 23 deforms and applies an elastic acting force to the hook 311, so that the elastic acting force of the elastic buckle 23 meets a preset value.
