Referring to fig. 1 to 4, the electronic device 100 may be any device having a functional element 200, such as: the mobile phone comprises intelligent equipment such as a mobile phone, a television, a tablet computer, a camera, a personal computer, a notebook computer, vehicle-mounted equipment, wearable equipment and the like. The functional component 200 is applied to the electronic device 100. The functional assembly 200 includes a base 210, a driving mechanism 220, a sliding seat 221, and a functional device 230. The base 210 has a receiving cavity 211. The functional device 230 is disposed on the sliding seat 221. The driving mechanism 220 is disposed in the receiving cavity 211. The driving mechanism 220 is used for driving the sliding seat 221 to slide. The sliding seat 221 is slidably connected to the base 210 to extend and retract the functional device 230 into the receiving cavity 211.

Referring to fig. 1 and 2, the sliding seat 221 at least accommodates a functional device 230. A plurality of functional devices 230, 230 'may be disposed in the sliding seat 221, wherein the plurality of functional devices 230, 230' may be the same or different. The functional device 230 may include one or more of a camera module, an earpiece module, a fingerprint module, an LED flash, a photosensor, a receiver, a microphone, and the like. The functional device 230' may include one or more of a camera module, an earpiece module, a fingerprint module, an LED flash, a photosensor, a receiver, a microphone, and the like. For example, the sliding seat 221 may be provided with a set of dual camera modules, a set of camera module and flash module, a set of camera module, flash module and receiver module, and so on. When the sliding seat 221 slides on the base 210, the functional device 230, 230' at least partially extends or retracts into the receiving cavity 211 along with the sliding of the sliding seat 221.

Referring to fig. 3 and 4, the base 210 includes a bottom plate 213 and a side plate 212 extending along a circumferential direction of the bottom plate 213. The extending direction of the side plate 212 intersects with the plane of the bottom plate 213. The bottom plate 213 and the side plate 212 enclose a receiving cavity 211.

Referring to fig. 3 to 8, the side plate 212 is provided with a through hole 217 communicating with the accommodating cavity 211. The sliding seat 221 is slidably retractable in the receiving cavity 211 through the through hole 217, so that the functional device 230 can at least partially extend out of or retract into the receiving cavity 211. In other embodiments, the through hole 217 may be disposed on the bottom plate 213.

In this embodiment, the sliding seat 221 is a square frame, and the through hole 217 is substantially rectangular. The shape of the through hole 217 is matched with that of the sliding seat 221, so that the sliding seat 221 can penetrate through the through hole 217 and cannot swing in the through hole 217, and the stability of the sliding seat 221 sliding out of the accommodating cavity 211 is improved. In other embodiments, the shape of the through hole 217 may also be circular, oval, triangular, irregular, etc. In this embodiment, the number of the through holes 217 is 1. In other embodiments, the number of the through holes 217 may be 2, 4, etc.

Referring to fig. 5 to 8, the driving mechanism 220 includes a tube 310, a driving member 320, a first piston 330 and a second piston 340. The first piston 330 and the second piston 340 are slidably coupled to an inner wall of the pipe 310. The first piston 330, the second piston 340 and the inner wall of the duct 310 form a sealed air chamber 350. The second piston 340 is connected to the functional device 230. The duct 310 is fixed to the base plate 213. The pipe 310 is hollow and cylindrical, and opposite ends of the pipe 310 are open. The first piston 330 and the second piston 340 are sealed at opposite ends of the duct 310, respectively, to form a sealed air chamber 350. It will be appreciated that the air pressure within the sealed air chamber 350 is balanced with the air pressure of the outside. When the first piston 330 moves towards the second piston 340, the second piston 340 will move back to the first piston 330 under the thrust of the gas in the gas chamber 350, so that the gas pressure in the sealed gas chamber 350 is balanced with the external gas pressure. When the first piston 330 moves away from the second piston 340, the second piston 340 moves toward the first piston 330 under the thrust of the external gas, so that the gas pressure in the sealed gas chamber 350 is balanced with the external gas pressure. The first piston 330 and the second piston 340 slide with respect to the inner wall of the duct 310, corresponding to the sealed air chamber 350 moving within the duct 310.

When the user needs to use the functional device 230, the driving member 320 drives the first piston 330 to move towards the second piston 340, and the second piston 340 drives the functional device 230 to extend out of the base 210 for use under the thrust of the gas in the gas chamber 350; when the user does not need to use the functional device 230, the driving member 320 drives the first piston 330 to move back to the second piston 340, and the second piston 340 drives the functional device 230 to retract into the base 210 under the thrust of the external gas, so that the use diversification of the electronic device 100 is realized, and the user experience is improved.

In this embodiment, the extending direction of the duct 310 is parallel to the sliding direction of the functional device 230. In other embodiments, the extending direction of the duct 310 may also intersect with the sliding direction of the functional device 230. In this embodiment, the functional device 230 is located between the duct 310 and the side plate of the base 210. In other embodiments, the functional device 230 may also be stacked with the duct 310 in a direction perpendicular to the sliding direction of the functional device 230.

Alternatively, the material of the first piston 330 and the second piston 340 may be an elastic material, such as rubber, elastic plastic, etc. Alternatively, the inner wall of the pipe 310 may be a polished surface to reduce sliding friction between the first and

second pistons

330 and 340 and the inner wall of the pipe 310.

In one embodiment, referring to fig. 5 to 8, the pipe 310 includes a first pipe 311 and a second pipe 312 connected to each other. The first tube 311 has the first inner cavity 313 therein, the second tube 312 has the second inner cavity 314 therein, and the first inner cavity 313 and the second inner cavity 314 are communicated. The first piston 330 is slidably connected to a sidewall of the first inner chamber 313, and the second piston 340 is slidably connected to a sidewall of the second inner chamber 314. The first inner cavity 313 and the second inner cavity 314 extend in the same direction. In other embodiments, the extending directions of the first inner cavity 313 and the second inner cavity 314 may also intersect.

In this embodiment, the cross-section of the first inner cavity 313 and the second inner cavity 314 is substantially square, and the first piston 330 and the second piston 340 are also substantially square, so that the first piston 330 and the second piston 340 can be prevented from rotating during the sliding process of the first inner cavity 313 and the second inner cavity 314, so that the first piston 330 and the second piston 340 can move along a straight line, and the functional device 230 can be driven to move along a straight line. In other embodiments, the cross-section of the first and

second lumens

313, 314 may be circular, elliptical, triangular, or other irregular shapes.

In this embodiment, the first duct 311 and the second duct 312 are long strips with different sizes, and the long strips of the first duct 311 and the second duct 312 can be attached to the bottom plate 213, so as to increase the stability between the duct 310 and the bottom plate 213. In addition, when the base 210 has a substantially square shape, the first and second

elongated conduits

311 and 312 are advantageous for arrangement in the base 210 and formation of a stacked structure with other devices.

Further, referring to fig. 6 and 8, in a direction perpendicular to the extending direction of the pipe 310, the area of the cross section of the first inner cavity 313 is larger than that of the cross section of the second inner cavity 314. Since the cross-sectional area of the first inner cavity 313 is larger than the cross-sectional area of the second inner cavity 314, the first piston 330 only needs to move a smaller distance in the first inner cavity 313 to move the second piston 340 a larger distance in the second inner cavity 314, so as to push the functional device 230 out of the receiving cavity. Therefore, the length of the first inner cavity 313 can be shortened by setting the area of the cross section of the first inner cavity 313 larger than the area of the cross section of the second inner cavity 314, and the shorter first inner cavity 313 is arranged in the limited space in the electronic device 100, so that the layout in the electronic device 100 can be more flexible, and the space utilization rate of the electronic device 100 can be improved.

Optionally, the ratio of the area of the cross section of the first inner cavity 313 to the area of the cross section of the second inner cavity 314 may be 2:1 to 5: 1. The proportional range can satisfy that the first piston 330 moves a small distance, i.e. the functional device 230 can be pushed out of the receiving cavity, and the cross-sectional area of the first inner cavity 313 is not too large, which results in the pipeline 310 occupying too much vertical space in the electronic device 100.

In one embodiment, referring to fig. 6 and 8, the tube 310 has a blocking wall 315 therein facing the first piston 330. The second inner cavity 314 communicates with the first inner cavity 313 through the blocking wall 315. When the user desires to use the function device 230, the driver 320 drives the first piston 330 towards the second piston 340. After the functional device 230 is fully extended out of the receiving cavity, the first piston 330 is up to abut against the blocking wall 315. The retaining wall 315 is configured to limit the movement distance of the first piston 330 toward the second piston 340, so as to prevent the functional device 230 from excessively protruding out of the receiving cavity.

By setting the cross-sectional area of the first inner cavity 313 and the cross-sectional area of the second inner cavity 314, a sidewall of the first inner cavity 313 can be used as the blocking wall 315 without additionally providing the blocking wall 315.

Further, referring to fig. 6 and 8, a first stopper 316 is disposed on a sidewall of the first inner cavity 313. The first stopper 316 is close to the opening at one end of the pipe 310, i.e. the first stopper 316 is far away from the second inner cavity 314. When the user does not need to use the function device 230, the driver 320 drives the first piston 330 back towards the second piston 340. When the functional device 230 is fully retracted into the receiving cavity, the first piston 330 abuts against the first stopper 316. The first limiting block 316 is configured to limit a moving distance of the first piston 330 away from the second piston 340, so as to prevent the first piston 330 from sliding out of the first inner cavity 313, and to prevent the functional device 230 from excessively retracting into the accommodating cavity.

It will be appreciated that the first piston 330 is driven by the driving member 320 to reciprocate between the first stopper 316 and the blocking wall 315.

Optionally, the number of the first limit blocks 316 may be multiple, and the multiple first limit blocks 316 are circumferentially disposed on the sidewall of the first inner cavity 313.

In an embodiment, referring to fig. 6 and 8, a second stopper 317 is disposed on a sidewall of the second inner cavity 314. The second stopper 317 is close to the opening at the other end of the pipeline 310, that is, the second stopper 317 is far away from the first inner cavity 313. When the functional device 230 extends out of the receiving cavity, the second piston 340 abuts against the second stopper 317. The second stopper 317 is configured to limit a moving distance of the second piston 340 away from the first piston 330, so as to prevent the second piston 340 from sliding out of the second inner cavity 314.

In other embodiments, referring to fig. 6 and 8, a third limiting block 318 may be further disposed on a sidewall of the second inner cavity 314, and the third limiting block 318 is disposed at a position of the second inner cavity 314 close to the first inner cavity 313. The third stopper 318 is configured to limit the distance the second piston 340 moves toward the first piston 330, so as to prevent the second piston 340 from sliding out of the second inner cavity 314 and into the first inner cavity 313.

In one embodiment, referring to fig. 5 to 8, the first piston 330 is a permanent magnet, and the driving member 320 is an electromagnetic coil. The solenoid is fixed to the base 210. The functional assembly 200 includes a controller 250. The controller 250 is electrically connected to the solenoid. The controller 250 is configured to control a current direction of the electromagnetic coil, so that the electromagnetic coil and the permanent magnet attract or repel each other to drive the permanent magnet to move toward or away from the second piston 340. Since the cross-sectional area of the first inner cavity 313 is larger than the cross-sectional area of the second inner cavity 314, the permanent magnet only needs to move a small distance in the first inner cavity 313 under the magnetic action of the electromagnetic coil, so that the second piston 340 can move a large distance in the second inner cavity 314. After the permanent magnet is far away from the electromagnetic coil, the permanent magnet cannot be separated from the magnetic action range of the electromagnetic coil due to the small moving distance of the permanent magnet, and can be close to the electromagnetic coil under the magnetic attraction of the electromagnetic coil.

In other embodiments, the first piston 330 is an electromagnetic coil and the driver 320 is a permanent magnet.

In other embodiments, the driver 320 may be a motor and a push rod connected to the first piston 330. The extending direction of the push rod is along the sliding direction of the functional device 230, and the motor drives the push rod to extend and retract so as to push the first piston 330 to move towards or away from the second piston 340.

The second piston 340 is connected to the functional device 230, which may be directly connected or indirectly connected through an intermediary, for example, the second piston 340 is directly connected to the functional device 230, or connected through a transmission such as a rope, chain, rod, etc.; the connection may also be a contactless connection, for example by magnetic force.

In one embodiment, referring to fig. 5-8, since the second piston 340 is disposed in the second inner cavity 314, the functional device 230 may be connected to the second piston 340 through a connecting rod 401. One end of the connecting rod 401 extends into the second inner cavity 314 and is connected to the second piston 340, and the other end of the connecting rod 401 is connected to the function device 230. The connecting rod 401 pushes or pulls the functional device 230 out of or into the receiving cavity 211 by the second piston 340.

In this embodiment, the extending direction of the connecting rod 401 may be parallel to the sliding direction of the functional device 230, and the functional device 230 may be disposed between the duct 310 and the side plate. In other embodiments, the functional device 230 may be disposed on one side of the pipe 310, and the functional device 230 may be disposed side by side with the second pipe 312.

In another embodiment, referring to fig. 9 and 13, the functional element 200 includes a first magnet 402. The first magnet 402 may be provided on the functional device 230. The second piston 340 is provided with a second magnet 403. The first magnet 402 and the second magnet 403 are permanent magnets that are magnetically attracted. The second piston 340 moves the second magnet 403. The first magnet 402 is magnetically attracted to the second magnet 403. The first magnet 402 is attached to the outer wall of the pipe 310 under the magnetic attraction of the second magnet 403, and carries the functional device 230 to extend out of or retract into the receiving cavity 211. The first magnet 402 may be disposed between the functional device 230 and the second conduit 312. In other embodiments, the first magnet 402 may be disposed at the trailing end of the functional device 230.

In this embodiment, the functional device 230 and the second piston 340 are connected by magnetic force, not by direct contact or snap connection. When the electronic device 100 falls or the functional device 230 receives an impact force in the sliding direction of the functional device 230, the functional device 230 receives a momentarily large impact force. During the transmission of the impact force to the base 210 through the functional device 230, the functional device 230 slides relative to the pipe 310 due to the magnetic connection between the functional device 230 and the second piston 340. The sliding of the functional device 230 can counteract part of the impact force to reduce the influence of the external impact force on the functional device 230, thereby greatly reducing the risk of damage to the functional device 230; the sliding of the functional device 230 can also retract the functional device 230 into the base 210, thereby preventing the functional device 230 from being exposed outside the base 210 and damaged by collision. Therefore, when the electronic device 100 falls or the functional device 230 is impacted, the functional device 230 can be offset by the magnetic connection between the functional device 230 and the base 210, so that a rigid collision is avoided, the functional device 230 is greatly protected, and the reliability and the service life of the electronic device 100 are increased.

Alternatively, the second piston 340 may be a magnet block, a composite block containing a magnetic material and an elastic material, or a mixed block in which the magnet block is disposed inside and the elastic material is disposed on the outer peripheral side wall.

Optionally, the wall thickness of the second tube 312 is less than 2mm to prevent too little magnetism between the first magnet 402 and the second magnet 403.

In this embodiment, referring to fig. 10, since the functional device 230 is connected to the second piston 340 by magnetic force, the second pipe 312 and the functional device 230 may be arranged side by side along the first direction (y direction). The first direction (y direction) is perpendicular to the sliding direction (x direction) of the camera module. The cross-sectional area of the second conduit 312 is smaller than the cross-sectional area of the first conduit 311. The second pipe 312 and the first pipe 311 form an L-shaped space, and the functional device 230 may be disposed in the L-shaped space, such that the functional device 230 is disposed side by side with the first pipe 311 in the x direction and is disposed side by side with the second pipe 312 in the first direction (y direction). In other embodiments, the first direction may intersect with but not perpendicular to the sliding direction of the functional device 230. The second duct 312 and the functional device 230 may be stacked or disposed side by side or staggered between the first duct 311 and the side plate to reduce the size of the second duct 312 and the functional device 230 in the sliding direction of the functional device 230.

In an embodiment, referring to fig. 10, in the sliding direction along the functional device 230, a portion of the outer peripheral sidewall of the second pipe 312 away from the functional device 230 is smoothly connected to the outer peripheral sidewall of the first pipe 311. That is, the second duct 312 is provided at the edge of the first duct 311. The space on one side of the second conduit 312 may be used to position the functional device 230 or other components.

In an embodiment, referring to fig. 10 and 11, a sliding groove 319 is further disposed on a peripheral side wall of the second pipeline 312. The sliding slot 319 extends in a direction parallel to the sliding direction of the functional device 230. The functional device 230 is slidably connected to the inner wall of the sliding slot 319. The sliding slot 319 is used to provide a direction for the functional device 230 to move toward or away from the through hole 217. Meanwhile, the sliding slot 319 can ensure the placing direction of the functional device 230, so that the situation that the placing direction of the functional device 230 is changed when the electronic device 100 is impacted, the functional device 230 cannot be aligned with the through hole 217, or the functional device 230 is prevented from being moved out of the through hole 217, therefore, the sliding slot 319 can drive the functional device 230 to be smoothly moved out of the through hole 217, and the moving resistance is reduced.

Referring to fig. 1 to 4, the electronic device 100 further includes a display screen 240, and the display screen 240 covers the base 210. The display screen 240 faces the bottom plate 213 and is stacked with the accommodating cavity 211. The display screen 240 and the base 210 form a receiving space for receiving a battery 243 and a main board 244. The display screen 240 includes a display area 241 to implement the display function of the electronic device 100. When the functional device 230 is retracted into the receiving cavity 211, the display area 241 partially or completely covers the functional device 230. Since the functional device 230 does not need to occupy the position of the display area 241, the display area 241 may have as large an area as possible, thereby increasing the screen occupation ratio of the display screen 240 and realizing that the display area 241 occupies the entire display screen 240.
