Referring to fig. 4, the functional assembly 200 includes a functional device 230, and the functional device 230 may include a camera module, and may further include one or more of an earphone module, a fingerprint module, an LED flash, a photosensor, a receiver, a microphone, and the like.

Fig. 4 and fig. 7 are schematic structural diagrams of a functional element 200 provided in an embodiment of the present application in two different states of extending out of the receiving cavity and retracting into the receiving cavity. Fig. 5 is a partially enlarged schematic view of fig. 4. Fig. 8 is a partially enlarged schematic view of fig. 7. Fig. 6 is a partial cross-sectional schematic view of fig. 4. Fig. 9 is a partial cross-sectional schematic view of fig. 7.

Referring to fig. 1, fig. 4 and fig. 7, the functional element 200 is applied to the electronic device 100, and the functional element 200 includes a base 210, and the base 210 has a receiving cavity 211. The functional assembly 200 includes a sliding seat 221, a functional device 230, and a driving mechanism 220. The driving mechanism 220 is disposed in the receiving cavity 211. The functional device 230 is disposed on the sliding seat 221. The sliding seat 221 is slidably connected to the base 210, so that the functional device 230 can be retracted into the receiving cavity 211 or at least partially extended out of the receiving cavity 211.

Referring to fig. 4 to 9, the driving mechanism 220 includes a driving member 222, a transmission member 223, a link chain 224', and an elastic member 225. The driving member 222 is fixed relative to the base 210 in the direction in which the sliding seat 221 moves. The transmission member 223 is connected between the driving member 222 and the sliding seat 221. The link chain 224' includes a plurality of links 224, the plurality of links 224 are sequentially sleeved on the transmission member 223 along the axial direction, adjacent links 224 are connected end to end, and the transmission member 223 is connected with the plurality of links 224 in a sliding manner.

Referring to fig. 7 to 9, the driving member 222 is used for pulling the transmission member 223. It can be understood that, before the driving member 222 pulls the transmission member 223, the distance between the driving member 222 and the sliding seat 221 is less than the sum of the total lengths of the plurality of connecting rods 224, and at this time, the plurality of connecting rods 224 extend in at least two different directions, i.e., the plurality of connecting rods 224 may be arranged at an angle.

Referring to fig. 7 to 9, when the driving element 222 pulls the transmission element 223, the transmission element 223 is tightened, the transmission element 223 pulls the plurality of connecting rods 224 under the pulling action of the driving element 222, and the plurality of connecting rods 224 approach each other under the pulling action of the transmission element 223 until they abut against each other to form a connecting rod chain 224'. The two ends of the link chain 224' respectively abut against the driving member 222 and the sliding seat 221. Since the plurality of connecting rods 224 are arranged at an included angle, that is, the extending direction of the connecting rod chain 224 'extends in a bending manner, the distance between the driving member 222 and the sliding seat 221 is smaller than the length of the connecting rod chain 224' in the direction in which the driving member 222 points to the sliding seat 221.

As the driving element 222 continues to pull the driving element 223, the pulling force of the driving element 223 drives the link chain 224 'to extend along the length in the direction in which the driving element 222 points to the sliding seat 221, i.e., the link chain 224' is in a straight state. The state of the link chain 224' being straightened may be a state in which the plurality of links 224 all extend in the same direction, or an included angle may be formed between the plurality of links 224, and the included angle may range from 120 ° to 180 °. Since the driving member 222 is fixed relative to the base 210 in the moving direction of the sliding seat 221, the link chain 224' pushes the sliding seat 221 to move and push the functional device 230 out of the receiving cavity 211.

Referring to fig. 4 to 6, after the driving element 222 releases the driving element 223, the driving element 223 is no longer pulled by the driving element 222, the driving element 223 is changed from a tight state to a loose state, and the driving element 223 no longer applies a pulling force to the connecting rod 224. The link chain is loosened, and the link chain 224' becomes a plurality of loose links 224, at which time the plurality of loose links 224 no longer abut against the sliding seat 221.

An elastic member 225 is disposed between the base 210 and the sliding seat 221. When the driving member 222 pulls the transmission member 223, the elastic member 225 is deformed because the pushing force of the link chain 224' to the sliding seat 221 is greater than the force of the elastic member 225. When the driving element 222 releases the transmission element 223, the plurality of connecting rods 224 are in a loose state, the connecting rods 224 no longer generate an urging force on the sliding seat 221, the elastic element 225 recovers, and the sliding seat 221 carries the functional device 230 to retract into the receiving cavity 211 under the recovering force of the elastic element 225.

When the functional device 230 is not needed, the functional device 230 can be hidden inside the base 210, and when the functional device 230 is needed, the functional device 230 can be extended out of the base 210 for use, so that the use diversification of the electronic device is realized, and the user experience is improved.

Optionally, the driving member 223 is a flexible rope, belt, chain, strip, rod, etc.

In one possible embodiment, the material of the connecting rod 224 may be an elastic material, such as rubber, elastic plastic, silicone, etc.

When the functional device 230 moves out of the receiving cavity 211, when the electronic device 100 falls or the sliding seat 221 is subjected to an impact force along the sliding direction of the sliding seat 221, since the sliding seat 221 is connected to the driving element 222 on the base 210 through the transmission element 223 and the connecting rod 224, the impact force is transmitted to the base 210 through the transmission element 223 and the connecting rod 224, and when the connecting rod 224 is subjected to an impact force along the moving direction of the sliding seat 221, since the material of the connecting rod 224 is an elastic material, the connecting rod 224 can elastically contract, so as to counteract a part of the impact force, so as to reduce the influence of the external impact force on the sliding seat 221, thereby greatly reducing the risk of damage to the functional device 230. The sliding seat 221 and the base 210 are connected movably, but not connected by being embedded or engaged with each other. When the electronic device 100 falls or the functional device 230 is impacted, the elastic link 224 can counteract the impact force, and the functional device 230 is greatly protected, so that the reliability and the service life of the electronic device 100 are increased.

Referring to fig. 1 to fig. 3, the electronic device 100 further includes a display screen 240, and the display screen 240 covers the base 210. The display screen 240 is stacked with the receiving cavity 211. 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. In addition, the display screen 240 and the functional device 230 are stacked, so that the processing such as hollowing or punching of the display screen 240 can be reduced, and the processing procedures of the display screen 240 are reduced, thereby improving the screen occupation ratio of the electronic device 100, facilitating the operation and improving the user experience.

In some possible embodiments, referring to fig. 2 and 3, the base 210 includes a bottom plate 213 and a side plate 212 extending along a circumference of the bottom plate 213. The extending direction of the side plate 212 intersects with the plane of the bottom plate 213. The display screen 240 faces the bottom plate 213, and the display screen 240 and the base 210 form an accommodating space for accommodating the battery 243 and the main board 244.

In other embodiments, the electronic device 100 may include a plurality of display screens, and may further include another display screen opposite to the display screen 240, in addition to the display screen 240 shown in fig. 2 and 3, so as to form a double-sided screen structure. That is, the bottom plate 213 and the side plate 212 may be covered with a display screen, and the electronic device 100 may be a double-sided display screen, a full-sided display screen, a flexible display screen, a foldable display screen, or the like.

In one embodiment, referring to fig. 2 to 6 and fig. 10, the side plate 212 is provided with a receiving opening 217 communicating with the receiving cavity 211. The sliding seat 221 is slidably retractable in the receiving cavity 211 through the receiving opening 217, so that the functional device 230 can at least partially extend out of or retract into the receiving cavity 211.

In this embodiment, the shape of the sliding seat 221 is matched with the shape of the receiving opening 217, so that the sliding seat 221 can penetrate through the receiving opening 217 and cannot swing in the receiving opening 217, thereby improving the stability of the sliding seat 221 sliding out of the receiving cavity 211.

In another embodiment, the receiving hole 217 may be formed in the bottom plate 213. The shape and number of the receiving openings 217 are not limited in the present application.

In an alternative embodiment, referring to fig. 4-7, the bottom plate 213 has a sliding slot 214. The slide groove 214 extends in a sliding direction parallel to the functional device 230. The sliding seat 221 is slidably connected to the sliding groove 214 of the bottom plate 213 and moves along the sliding groove 214. The sliding groove 214 is used for providing a direction for the sliding seat 221 to move towards or away from the receiving opening 217. Meanwhile, the sliding groove 214 may further limit the degree of freedom of the sliding seat 221, so that the sliding seat 221 can only slide in a direction toward the receiving opening 217, and therefore, when the electronic device 100 is impacted, the sliding groove 214 may prevent the orientation of the sliding seat 221 from changing, so that the sliding seat 221 cannot be aligned with the receiving opening 217, or the sliding seat 221 cannot be prevented from moving out of the receiving opening 217.

In one possible embodiment, referring to fig. 4-9, the driving member 222 includes a motor 2221 and a rotating rod 2222. The motor 2221 is fixed to the base 210, and the rotating rod 2222 is fixed to the base 210 in the moving direction of the sliding seat 221. The transmission member 223 is connected to the rotating rod 2222, and the rotating rod 2222 is connected to the motor 2221. The motor 2221 is configured to drive the rotating rod 2222 to rotate around the central axis of the rotating rod 2222, so as to pull or release the transmission member 223.

In one possible implementation, referring to fig. 4 and 7, the functional component 200 further includes a controller 250. The controller 250 is electrically connected to the motor 2221.

Specifically, referring to fig. 4 to 6, when the motor 2221 drives the rotating rod 2222 to rotate around the first direction (clockwise or counterclockwise) under the action of the controller 250, the transmission member 223 is gradually wound around the rotating rod 2222 under the pulling force of the rotating rod 2222, the length of the transmission member 223 between the driving member 222 and the sliding seat 221 is reduced, so that the transmission member 223 pulls the plurality of connecting rods 224, and the plurality of connecting rods 224 abut against each other under the action of the transmission member 223 to form a connecting rod chain 224'. The two ends of the link chain 224' respectively abut against the driving member 222 and the sliding seat 221. Under the continuous pulling action of the rotating rod 2222, the length of the transmission member 223 between the driving member 222 and the sliding seat 221 is further reduced, so that the link chain 224' in the bent state is gradually straightened. During the process of straightening the link chain 224 ', since the distance between the driving element 222 and the sliding seat 221 is smaller than the length of the link chain 224' in the straightened state, the link chain 224 'will generate a pushing force on the driving element 222 and the sliding seat 221, and since the driving element 222 is fixed relative to the base 210, the link chain 224' will push the sliding seat 221 to slide in the sliding slot, so as to extend the functional device 230 on the sliding seat 221 out of the receiving cavity 211, so that the functional device 230 can be used by the user.

Referring to fig. 7 to 9, after the use of the functional device 230 is finished, when the motor 2221 drives the rotating rod 2222 to rotate around the second direction (counterclockwise or clockwise) under the action of the controller 250, the rotating rod 2222 releases the transmission member 223, the transmission member 223 is changed from a tightened state to a loosened state, the transmission member 223 no longer generates an acting force on the connecting rods 224, the connecting rod chain 224' is changed into a plurality of loose connecting rods 224, the sliding seat 221 loses the pushing force of the connecting rods 224, and moves under the action of the restoring force of the elastic member 225, so that the functional device 230 retracts into the accommodating cavity 211, the functional device 230 is prevented from being damaged, and dust and moisture are reduced from entering the functional device 230.

It is to be understood that the first direction may be a clockwise or counterclockwise direction, the first direction being opposite to the second direction.

In other embodiments, the rotating rod 2222 may also be arranged perpendicular to the bottom plate 212.

In one possible embodiment, referring to fig. 6 and 9, the functional assembly 200 includes a first blocking member 2223 located between the driving member 222 and the link chain 224. The first blocking member 2223 is fixed on the base 210. The first blocking member 2223 may be a sleeve 2223 sleeved on the rotating rod 2222. Wherein the rotating rod 2222 rotates within the sleeve 2223. The first blocking member 2223 may also be a plate member disposed between the driving member 222 and the link chain 224. The first blocking part 2223 is provided with a first through hole 2224, and the transmission part 223 penetrates through the first through hole 2224 and is connected to the rotating rod 2222.

Further, the size of the first through hole 2224 is smaller than the radial size of the link chain 224'. When the driving element 222 pulls the transmission element 223, one end of the link chain 224' abuts against the opening of the first through hole 2224.

Alternatively, the first blocking member 2223 is used to allow the transmission member 223 to pass through, but prevent the connecting rod 224 from passing through, so the first blocking member 2223 can be replaced by a baffle fixed on the base 210.

In one possible embodiment, referring to fig. 6 and 9, the sliding seat 221 has a second blocking member 2211. The second blocking member 2211 is disposed on a side of the sliding seat 221 close to the driving member 222. The second blocking member 2211 is provided with a second through hole 2212, and the transmission member 223 passes through the second through hole 2212 and is connected to the sliding seat 221.

Further, the size of the second through hole 2212 is smaller than the radial size of the link chain 224 ', and when the driving element 222 pulls the transmission element 223, one end of the link chain 224' abuts against the opening of the second through hole 2212.

The second blocking member 2211 functions similarly to the first blocking member 2223 to allow the transmission member 223 to pass through, but prevent the connection rod 224 from passing through. It can be understood that when the functional device 230 is disposed in the receiving cavity 211, the distance between the second blocking member 2211 and the first blocking member 2223 is less than the sum of the lengths of the plurality of connecting rods 224, so that when the transmission member 223 is pulled, the plurality of connecting rods 224 form a connecting rod chain 224 ', and two ends of the connecting rod chain 224' abut against the second blocking member 2211 and the first blocking member 2223. As the link chain 224 'is straightened, the link chain 224' pushes the second blocking member 2211 of the sliding seat 221, and the sliding seat 221 slides along the sliding slot.

First embodiment

Referring to fig. 10, end surfaces of the two opposite ends of the connecting rod 224 are arc end surfaces 2244.

In this embodiment, referring to fig. 6 and 9, when the plurality of connecting rods 224 abut against each other in different directions, the plurality of connecting rods 224 rotate to extend in the same direction along with the further pulling action of the transmission member 223. Because the end surfaces of the two opposite ends of the connecting rods 224 are arc end surfaces, the plurality of the abutting connecting rods 224 can be prevented from being blocked in the rotating process, so that the plurality of the abutting connecting rods 224 can rotate smoothly.

Further, when the link 224 abuts against the first blocking member 2223 and the second blocking member 2211, the arc end surface of the link 224 may partially pass through the first through hole 2224 and the second through hole 2212, so that one end of the link 224 is engaged with the first blocking member 2223 and the other end of the link 224 is engaged with the second blocking member 2211, and the plurality of links 224 may smoothly extend in the direction of the second through hole 2212 along the first through hole 2224 during the further pulling of the driver 223. Optionally, the first through-hole 2224 may be aligned with the second through-hole 2212.

Second embodiment

Fig. 11 is a schematic structural diagram of a connecting rod according to a second embodiment of the present application. Fig. 12 and 13 are schematic structural views of a link chain according to a second embodiment of the present application. Referring to fig. 11, an end surface of at least one end of the connecting rod 224 is a combining surface 2241. The combined surface 2241 comprises a plane 2242 and an arc surface 2243 which are connected. Referring to fig. 12 and 13, the link chain 224' includes a first link 224a, a second link 224b and an intermediate link 224c disposed between the first link 224a and the second link 224 b. The intermediate link 224c may be plural. The combined surface of the first link 224a abuts against the combined surface of the intermediate link 224 c.

Further, referring to fig. 12, both ends of the first link 224a and the second link 224b are respectively an arc surface 2244 and the combination surface 2241. The arc surface 2244 is used for abutting against the second blocking part or the first blocking part 2223. Two opposite ends of the middle connecting rod 224c are respectively the two combination surfaces 2241 and 2241' that are inverted from each other.
