Referring to fig. 1, a functional device 100 according to an embodiment of the present disclosure is shown. The functional component 100 can be applied to an electronic device 200. The electronic device 200 according to the embodiment of the present application may be any device having communication and storage functions, for example: the system comprises intelligent equipment with a network function, such as a tablet Computer, a mobile phone, an electronic reader, a remote controller, a Personal Computer (PC), a notebook Computer, vehicle-mounted equipment, a network television, wearable equipment and the like.

Referring to fig. 2 to 5, the functional assembly 100 includes a base 1, a sliding seat 2, a sleeve assembly 3, a piston 4, a driving member 5 and a pulling member 6. The sliding seat 2 is telescopically and slidably connected to the base 1. The sliding seat 2 is provided with a camera module 21. The camera module 21 moves along with the sliding seat 2. The sleeve assembly 3 is located within the base 1. The sleeve assembly 3 internally forms a transmission chamber 30. The sleeve assembly 3 is provided with a bypass 31. The branch 31 communicates the transmission chamber 30 with the outside of the sleeve assembly 3. The branch 31 is provided with a valve 32, and the valve 32 is used for conducting or cutting off the branch 31. One end of the sleeve component 3 is sealed and fixedly connected with the sliding seat 2. The piston 4 is slidably and sealingly connected to the other end of the sleeve assembly 3. The driving piece 5 is fixed in the base 1. The pulling member 6 is connected between the piston 4 and the base 1.

When the driving piece 5 drives the piston 4 to slide towards the direction close to the sliding seat 2, the valve 32 cuts off the branch 31, the sleeve component 3 is unfolded to push the sliding seat 2, and the camera module 21 extends out of the base 1. When the driving piece 5 drives the piston 4 to slide in the direction away from the sliding seat 2, the piston 4 is pulled by the pulling piece 6 to pull the sliding seat 2, the sleeve component 3 contracts, and the camera module 21 retracts into the base 1. When the sliding seat 2 receives an external force towards the inside of the base 1, the valve 32 conducts the branch 31, and the sleeve component 3 contracts, so that the sliding seat 2 carries the camera module 21 to retract into the base 1.

In this embodiment, when the valve 32 cuts off the branch 31, the transmission cavity 30 is hermetically disposed, so that when the driving element 5 drives the piston 4 to slide in a direction approaching the sliding seat 2, the piston 4 presses the gas in the transmission cavity 30, and the pressure of the gas in the transmission cavity 30 is greater than the sliding resistance between the sliding seat 2 and the base 1, so that the sleeve assembly 3 can be unfolded by the gas in the transmission cavity 30 and the sliding seat 2 can be pushed, so that the sliding seat 2 carries the camera module 21 to extend out of the base 1 (as shown in fig. 4). When the piston 4 slides away from the sliding seat 2, the piston 4 can pull the sliding seat 2 through the pulling member 6, and the sleeve assembly 3 contracts, so that the sliding seat 2 carries the camera module 21 to retract into the base 1 (as shown in fig. 3). Because the camera module 21 can retract into the base 1 when not in use, so as to reduce the use volume of the electronic device 200 using the functional component 100, the electronic device 200 is convenient for a user to carry, and the camera module 21 can extend out of the base 1 when working, so as to interact with the user, so that the functional component 100 improves the user experience.

Because the valve 32 conducts the branch 31 when the sliding seat 2 receives an external force toward the inside of the base 1, the branch 31 communicates the transmission cavity 30 and the outside of the sleeve component 3, the air in the transmission cavity 30 can flow out through the branch 31, and the sleeve component 3 can be retracted under the external force, so that the sliding seat 2 carries the camera module 21 to retract into the base 1, when the sliding seat 2 extends out of the base 1, if a user presses the sliding seat 2 or the sliding seat 2 is impacted toward the base 1, the sliding seat 2 is close to the piston 4, the sleeve component 3 retracts, and the sliding seat 2 can carry the camera module 21 to retract into the base 1 (as shown in fig. 5), thereby preventing the camera module 21 from being damaged due to rigid impact or manual pressing by the user, the functional assembly 100 and the electronic device 200 have high reliability and more diversified use environments.

When the piston 4 slides away from the sliding seat 2, the valve 32 can be in a closed state to block the branch 31 or in an open state to conduct the branch 31, because the volume of the transmission chamber 30 hardly changes.

It is understood that in other embodiments, the camera module 21 may be replaced by other functional devices, including but not limited to any one or more combinations of iris recognition module, face recognition module, flash, microphone, receiver, photoreceptor, fingerprint module, and keys. The piston 4 is connected with the sleeve component 3 in a sliding and sealing mode, that is, air in the transmission cavity 30 cannot leak out of a gap between the piston 4 and the sleeve component 3, so that the air tightness of the transmission cavity 30 is high.

Wherein the valve 32 is a two-way valve. The transmission chamber 30 can be supplied with air or discharged with air through the branch 31 and the valve 32. The valve 32 may be a solenoid valve, or a differential pressure regulating valve. When the valve 32 is a differential pressure regulating valve, the valve 32 is automatically opened after the differential pressure on the two sides of the valve 32 reaches a threshold value. The threshold value may be empirically calculated such that the valve 32 remains closed during normal operation of the functional assembly 100 and the valve 32 opens to allow deflation when the functional assembly 100 is in a hand-pressed or dropped state.

Wherein the driving member 5 comprises a motor and a transmission member (not shown in the figure). The transmission member is connected between the motor and the piston 4. The transmission piece is used for converting the rotation action of the motor into the sliding action of the piston 4, so that the driving piece 5 can drive the piston 4 to slide. There are various implementations of the transmission member, including but not limited to gear and rack engagement, lead screw and slider engagement, and the like.

The end of the branch 31 remote from the transmission chamber 30 may be provided with various structures, so that the gas in the transmission chamber 30 can flow to or from another chamber through the branch 31. For example:

in one embodiment, referring to fig. 2 to 5, the functional assembly 100 further includes an air bag 71, and the air bag 71 is fixed on a side of the branch 31 away from the transmission cavity 30. The airbag 71 forms inside it a further chamber connected to the branch 31, which is different from the transmission chamber 30. When the valve 32 conducts the branch 31, the air bag 71 is communicated with the transmission cavity 30. When a user presses the sliding seat 2 or the sliding seat 2 is impacted by the base 1, the gas in the transmission cavity 30 enters the gas bag 71 through the branch 31, so that the sleeve component 3 can be quickly contracted, the sliding seat 2 carries the camera module 21 to be retracted into the base 1, and the damage of the camera module 21 caused by rigid impact or manual pressing by the user is avoided.

The air bag 71 is made of elastic materials, so that the volume of the air bag 71 can be increased when the air bag is inflated, and the volume of the air bag 71 can be reduced when the air bag is not inflated.

In another embodiment, referring to fig. 6 and 7, the functional assembly 100 further includes a dust screen 72. The dust screen 72 is disposed on the branch 31. At this time, the base 1 is internally formed with another chamber different from the transmission chamber 30 connected to the branch 31. When the valve 32 opens the branch 31, the transmission cavity 30 discharges or admits air through the dust screen 72. When a user presses the sliding seat 2 or the sliding seat 2 is pressed towards the base 1, the gas in the transmission cavity 30 enters the base 1 through the branch 31 and the dustproof net 72, so that the sleeve component 3 can be quickly contracted, the sliding seat 2 carries the camera module 21 to be retracted into the base 1, and the camera module 21 is prevented from being damaged due to rigid impact or manual pressing of the user.

The dust screen 72 can isolate dust and the like when the gas inside the base 1 enters the transmission cavity 30, so as to keep the cleanliness of the gas in the transmission cavity 30, so that the telescopic action of the sleeve assembly 3 is smooth, and the service life of the sleeve assembly 3 is long.

As shown in fig. 6, the valve 32 is disposed on a side of the branch 31 away from the transmission cavity 30, and the dust-proof net 72 covers the vent 321 of the valve 32 away from the branch 31. Alternatively, as shown in fig. 7, the valve 32 is disposed in the middle of the branch 31, and the dust screen 72 covers the port 311 of the branch 31 far from the transmission chamber 30. At this time, the dustproof effect of the dustproof net 72 is better, and dust can be prevented from entering the valve 32, so that the service life of the valve 32 is prolonged.

It can be understood that, in the present embodiment, the interior of the base 1 is directly utilized as another chamber connected to the branch 31, which is different from the transmission chamber 30, so that there is no need to provide another structure capable of forming a chamber, and thus the cost and the occupied space of the functional assembly 100 can be saved.

In another embodiment, referring to fig. 8 to 11, the functional module 100 further includes a breathable waterproof film 73. The air-permeable waterproof film 73 is permeable to air and moisture and dust. The base 1 is provided with a through hole 10, and the through hole 10 is communicated with the inside of the base 1 and the outside of the base 1. The air-permeable waterproof film 73 covers the through hole 10. The port 311 of the branch 31 far away from the transmission cavity 30 is opposite to the air-permeable waterproof membrane 73. When the valve 32 is used for conducting the branch 31, the transmission cavity 30 is used for air outlet or air inlet through the air-permeable waterproof membrane 73. When the user presses the sliding seat 2 or the sliding seat 2 is pressed towards the base 1, when the base 1 is impacted, the gas in the transmission cavity 30 flows to the outside of the base 1 through the branch 31 and the breathable waterproof membrane 73, so that the sleeve component 3 can be quickly contracted, the sliding seat 2 carries the camera module 21 to be retracted into the base 1, and the damage of the camera module 21 caused by rigid impact or manual pressing of the user is avoided.

The functional assembly 100 further includes a metal mesh 74, and the metal mesh 74 is received in the through hole 10 and covers the air-permeable waterproof membrane 73. The metal mesh 74 and the air-permeable waterproof film 73 are stacked, and the metal mesh 74 can protect the air-permeable waterproof film 73. The metal mesh 74 may be recessed into an accommodating space, and the air-permeable waterproof film 73 is disposed in the accommodating space. The metal mesh 74 covers the side of the air-permeable and waterproof membrane 73 remote from the branch 31.

As shown in fig. 9 and 10, the valve 32 is disposed on a side of the branch 31 away from the transmission cavity 30, the valve 32 is at least partially accommodated in the through hole 10, and the air-permeable waterproof membrane 73 covers an air vent of the valve 32 away from the branch 31. Alternatively, as shown in fig. 11 and 12, the valve 32 is disposed in the middle of the branch 31, the end portion of the branch 31 away from the transmission cavity 30 is accommodated in the through hole 10, and the air-permeable waterproof membrane 73 covers the port of the branch 31 away from the transmission cavity 30. The valve 32 or the branch 31 is partially accommodated in the through hole 10, can directly abut against the breathable waterproof membrane 73, is accurately positioned and reliably connected with each other, and the transmission cavity 30 can smoothly discharge air or intake air through the breathable waterproof membrane 73.

Of course, in other embodiments, the end of the branch 31 away from the transmission chamber 30 may be directly open to the inside of the base 1 without providing other components. In this case, the valve 32 may be disposed at an end of the branch 31 away from the transmission chamber 30, or at a middle portion of the branch 31.

In one embodiment, referring to fig. 2 and 3, the sleeve assembly 3 further includes a first sleeve 33 and a second sleeve 34. The first sleeve 33 is fixed in the base 1. The branch 31 is fixedly connected with the first sleeve 33. The branch 31 communicates with the inner cavity 330 of the first sleeve 33 towards the port 312 of the first sleeve 33. The head end 341 of the second sleeve 34 is telescopically sealed inside the first sleeve 33. The second sleeve 34 is slidably inserted into the first sleeve 33. The inner cavity 340 of the second sleeve 34 communicates with the inner cavity 330 of the first sleeve 33 to form the transmission cavity 30. The branch 31 connects the transmission chamber 30. The tail end 342 of the second sleeve 34 is sealed and fixed to the sliding seat 2. The piston 4 is slidably connected to the second sleeve 34 and seals the transmission chamber 30.

It can be understood that the head end 341 of the second sleeve 34 is sealingly sleeved on the first sleeve 33, which means that air in the transmission cavity 30 cannot leak out from a gap between the head end 341 of the second sleeve 34 and the first sleeve 33, so that the transmission cavity 30 has high air tightness.

The cross-sectional shapes of the first sleeve 33 and the second sleeve 34 may be various, such as square, circle, oval, triangle, etc., which is not limited in this application.

In one embodiment, referring to fig. 3 and 6, an end of the pulling element 6 away from the piston 4 is connected to a head end 341 (shown in fig. 3) of the second sleeve 34 or a tail end 342 (shown in fig. 6) of the second sleeve 34. The pulling element 6 is connected to the sliding seat 2 via the second sleeve 34, so that the length of the pulling element 6 can be shortened. The first end 341 of the second sleeve 34 is connected to the pulling element 6 for illustration. The drawing piece 6 is accommodated in the transmission cavity 30, so that the air tightness of the transmission cavity 30 can be prevented from being damaged.

The pulling element 6 can be bent, so that the sliding seat 2 can be bent and folded when being retracted into the base 1 by an external force, and the second sleeve 34 can be smoothly retracted into the first sleeve 33. The pulling element 6 can be free or very little deformed when subjected to tensile forces.

For example, the pulling member 6 is a strip formed by twisting two or more strands of fibers or wires. Including but not limited to cotton, hemp, palm, and the like. Alternatively, the pulling element 6 may be a chain comprising a plurality of links linked in sequence, wherein the plurality of links are movable relative to each other.

The number of the drawing pieces 6 is multiple, and the drawing pieces 6 are arranged at intervals. The plurality of pulling members 6 are uniformly arranged along the circumferential direction of the inner cavity 340 of the second sleeve 34, so that the piston 4 pulls the second sleeve 34 and the sliding seat 2 more stably.

In one embodiment, referring to fig. 3, a gap 332 is formed between an outer sidewall 343 of the second sleeve 34 and an inner sidewall 331 of the first sleeve 33, so that the sliding resistance of the second sleeve 34 relative to the first sleeve 33 is small, and the extending and retracting actions of the second sleeve 34 relative to the first sleeve 33 are smoother and have less power consumption. The sealing element 8 is sleeved outside the head end 341 of the second sleeve 34. The seal 8 abuts against the inner side wall 331 of the first sleeve 33. The seal 8 is in interference fit with the inner side wall 331 of the first sleeve 33. The seal 8 seals between the outer side of the head end 341 of the second sleeve 34 and the inner side wall 331 of the first sleeve 33, thereby achieving a sealed connection between the second sleeve 34 and the first sleeve 33. The seal 8 moves with the second sleeve 34.

Wherein, the sealing element 8 and the second sleeve 34 are integrally formed, so as to increase the connection firmness therebetween and reduce the production cost. Alternatively, the seal 8 snaps or screws into the second sleeve 34. The seal 8 is annular.

In one embodiment, referring to fig. 3 and 12, the first sleeve 33 is provided with a guiding element 9 inside. The guide 9 is fixed to the first sleeve 33. The guide 9 abuts against the second sleeve 34. The second sleeve 34 is slidable relative to the guide 9. The guide 9 is used to prevent the second sleeve 34 from shaking when being expanded or contracted relative to the first sleeve 33, so that the sliding of the sliding seat 2 is more stable.

Wherein the guide 9 is arranged at the end of the first sleeve 33 facing the sliding seat 2, so that the arrangement of the guide 9 does not affect the movement of the sealing element 8, resulting in a high reliability of the functional assembly 100.

Wherein the guide 9 is ring-shaped. The guide 9 is provided with a plurality of hollow-out areas 91, and the plurality of hollow-out areas 91 penetrate through the guide 9 along the axial direction of the first sleeve 33. At this time, the air on the two opposite sides of the guide 9 can pass through the plurality of hollow areas 91 and be conducted with each other, so as to prevent the gap from forming a closed space to hinder the movement of the second sleeve 34, and thus the reliability of the functional assembly 100 is high. The plurality of hollow-out areas 91 are uniformly arranged along the circumferential direction of the first sleeve 33.

In one embodiment, referring to fig. 3 and 13, the first sleeve 33 is a steel tube and the second sleeve 34 is a flexible tube. Since the second sleeve 34 is a flexible tube, the second sleeve 34 can be deformed during the movement relative to the first sleeve 33, and therefore the first sleeve 33 can include a curved section, thereby making the arrangement between the various components of the functional assembly 100 more compact. For example, as shown in fig. 13, the first sleeve 33 has an L-shape. Of course, in other embodiments, the first sleeve 33 may have a U-shape or other shapes.

Wherein the hose is bendable so as to be able to follow the shape of the first sleeve 33 when moved. The hose can be free or minimally deformed when subjected to tensile forces, so that the sliding seat 2 can be pulled. Wherein the hose can be one or more of stainless steel hose, metal hose, corrugated hose, rubber hose, plastic hose. Of course, in other embodiments, the second casing may be a steel pipe.

In one embodiment, referring to fig. 2, 3, 14 and 15, the base 1 includes a bottom plate 11 and a frame 12 connected to a periphery of the bottom plate 11. The frame 12 is provided with a telescopic opening 121. The expansion port 121 communicates between the inside of the base 1 and the outside of the base 1. The sliding seat 2 is slidably connected to the frame 12 through the expansion port 121, so that the camera module 21 extends out of or retracts into the base 1 through the expansion port 121. The bottom plate 11 may be a rear cover or a middle partition plate of the electronic device 200. The frame 12 may be a peripheral frame of the electronic device 200.

In the present embodiment, the bezel 12 covers and hides the sliding seat 2, so as to improve the appearance and safety of the functional assembly 100. Because the expansion port 121 is disposed on the frame 12, the camera module 21 extends and contracts at the side of the base 1, that is, the camera module 21 extends and contracts at the side of the electronic device 200, and the camera module 21 does not occupy the front space of the electronic device 200, so as to avoid the limitation on the screen occupation ratio of the electronic device 200.

The first sleeve 33 and the driving member 5 are fixed on the bottom plate 11. The bottom plate 11 carries the slide shoe 2.

Wherein, the outer peripheral side wall of the sliding seat 2 is in clearance fit with the inner peripheral side wall of the expansion port 121.
