Referring to fig. 1, 4 to 6, fig. 4 and 6 are schematic structural views of a functional element 200 provided in an embodiment of the present application in two different states of extending out of a receiving cavity and retracting into the receiving cavity. Fig. 5 is a partially enlarged schematic view of fig. 4. The functional assembly 200 is applied to the mobile terminal 100, and the functional assembly 200 includes a functional device 230, a housing 210, and a driving mechanism 220 disposed in the housing 210. The housing 210 has a receiving cavity 211. The functional device 230 may be retracted into the receiving cavity 211 or at least partially extended out of the receiving cavity 211.

Referring to fig. 5 and 6, the driving mechanism 220 includes a sliding seat 221, a telescopic member 222, and a driving member 226. The driver 226 includes a first driver 223 and a second driver 224. The functional device 230 is accommodated in the sliding seat 221, and the sliding seat 221 moves to make the functional device 230 slide in the accommodating cavity 211 in a telescopic manner. The telescopic member 222 includes first and

second struts

2221 and 2222 which are staggered and a rotation shaft 2223 which hinges the first and

second struts

2221 and 2222. The first strut 2221 includes a first end 2224 and a second end 2225, and the second strut 2222 includes a third end 2226 and a fourth end 2227. The first end 2224 and the third end 2226 are rotatably coupled to the driver 226. Specifically, the first end 2224 and the third end 2226 are respectively rotatably connected to the first driving member 223 and the second driving member 224. The second end 2225 and the fourth end 2227 are slidably connected to the sliding seat 221.

The first driving member 223 and the second driving member 224 move toward or away from each other to drive the first end 2224 and the third end 2226 to move toward or away from each other, when the first end 2224 and the third end 2227 move toward or away from each other, the first support bar 2221 and the second support bar 2222 rotate around the rotating shaft 2223, the second end 2225 moves away from or toward the third end 2226, the fourth end 2227 moves away from or toward the first end 2224, and the fourth end 2227 moves toward or away from the second end 2225, so as to drive the sliding seat 221 to move, and extend or retract the functional device 230 into or out of the housing 210.

In this embodiment, referring to fig. 5 and fig. 6, the first driving element 223 and the second driving element 224 are close to each other from their initial positions (see fig. 5), so as to drive the first end 2224 and the third end 2227 to be close to each other, so that the telescopic element 222 is in a folded state, the length of the telescopic element 222 in the sliding direction along the sliding seat 221 is increased, and the telescopic element 222 pushes the sliding seat 221 to move in a direction away from the first driving element 223 and the second driving element 224, so as to drive the functional device 230 to extend out of the housing 210; the first driving member 223 and the second driving member 224 are controlled to return to their initial positions, that is, the first driving member 223 and the second driving member 224 move away from each other to move the first end 2224 and the third end 2227 away from each other, so that the telescopic member 222 is in the expanded state, the length of the telescopic member 222 in the sliding direction along the sliding seat 221 decreases, and the telescopic member 222 pulls the sliding seat 221 to move towards the direction of the first driving member 223 and the second driving member 224, so as to drive the functional device 230 to retract into the housing 210.

By arranging the sliding seat 221, the telescopic member 222, the first driving member 223 and the second driving member 224 in the housing 210, the functional device 230 is accommodated in the sliding seat 221, the first driving member 223 and the second driving member 224 drive the first end 2224 and the third end 2227 of the telescopic member 222 to approach or separate from each other, so that the telescopic member 222 is in a folded state or an unfolded state, so that the length of the telescopic member 222 in the sliding direction of the sliding seat 221 is increased or decreased, and the telescopic member 222 drives the sliding seat 221 to move towards or away from the direction in which the first driving member 223 and the second driving member 224 are located, so as to drive the functional device 230 to extend out of or retract into the housing 210. When the functional device 230 is not needed to be used, the functional device 230 can be hidden inside the housing 210, and when the functional device 230 is needed to be used, the functional device 230 can be extended out of the housing 210 for use, so that the use diversification of the mobile terminal is realized, and the user experience is improved.

In this embodiment, the sliding seat 221 is connected to the housing 210 through the telescopic member 222, the first driving member 223 and the second driving member 224, and since the telescopic member 222 can be elastically telescopic, the connection between the sliding seat 221 and the housing 210 is an elastic contact connection, rather than a connection that is embedded or engaged with each other. When the mobile terminal 100 falls or the sliding seat 221 is subjected to an impact force along the sliding direction of the sliding seat 221, the sliding seat 221 is subjected to a transient large impact force, and the impact force is transmitted to the housing 210 through the telescopic member 222, the first driving member 223 and the second driving member 224, and the telescopic member 222 is deformed after the impact force, on one hand, the deformation of the telescopic member 222 can offset a part of the impact force, so as to reduce the influence of an external impact force on the sliding seat 221, thereby greatly reducing the risk of damage to the functional device 230; on the other hand, the deformation of the telescopic member 222 can make the sliding seat 221 retract into the housing 210, thereby preventing the functional device 230 from being exposed outside the housing 210 and damaged by collision. Therefore, the sliding seat 221 and the housing 210 are connected by the telescopic member 222, so that when the mobile terminal 100 falls or the functional device 230 is impacted, the impact force can be counteracted, and the functional device 230 is greatly protected, thereby increasing the reliability and the service life of the mobile terminal 100.

Referring to fig. 1 to fig. 3, the mobile terminal 100 further includes a display screen 240, and the display screen 240 covers the housing 210. The display screen 240 is stacked with the receiving cavity 211. The display screen 240 includes a display area 241 to implement a display function of the mobile terminal 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 mobile terminal 100, facilitating the operation and improving the user experience.

When the functional device 230 needs to be used, the driving mechanism 220 drives the functional device 230 to extend out of the housing 210 from the side surface of the mobile terminal 100 for use, so that the use diversification of the mobile terminal 100 is realized, and the user experience is improved. After the use of the functional device 230 is finished, the driving mechanism 220 retracts the functional device 230 into the housing 210 from the side of the mobile terminal 100, thereby protecting the functional device 230 from impact damage or moisture and dust.

In some possible embodiments, referring to fig. 2 and 3, the housing 210 of the functional assembly 200 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 housing 210 form an accommodating space for accommodating the battery 243 and the main board 244.

Further, referring to fig. 3, the housing 210 includes a top plate 214 disposed opposite to the bottom plate 213. The display screen 240 is mounted on the top plate 214. The top plate 214, the bottom plate 213, and the side plates 212 form a receiving cavity 211, and the driving mechanism 220 and the functional device 230 are received in the receiving cavity 211. Alternatively, the top plate 214 may be fixed to the main plate 244, or the top plate 214 may be the main plate 244.

In other embodiments, the mobile terminal 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 mobile terminal 100 may be a double-sided display screen, a full-sided display screen structure, a flexible display screen, a foldable display screen, or the like.

In one embodiment, referring to fig. 2 to 6, the side plate 212 is provided with a through hole 217 facing the sliding seat 221, and the sliding seat 221 is slidably and telescopically inserted into 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 this embodiment, the shapes of the sliding seat 221 and the through hole 217 are matched, so that the sliding seat 221 can penetrate through the through hole 217 and cannot swing in the through hole 217, thereby improving the stability of the sliding seat 221 sliding out of the accommodating cavity 211.

In other embodiments, the through hole 217 may be further disposed on the bottom plate 213. The shape and number of the through holes 217 are not limited in the present application.

Referring to fig. 7 to 10, the number of the first supporting bar 2221 and the second supporting bar 2222 may be multiple. For example,

first struts

2221a and 2221b,

second struts

2222a and 2222 b. The adjacent

first struts

2221a and 2221b are hinged end to end, and the adjacent

second struts

2222a and 2222b are hinged end to end. The plurality of first struts and the plurality of second struts are hinged to each other in a one-to-one correspondence manner, that is, the first struts 2221a are hinged to the second struts 2222a, and the first struts 2221b are hinged to the second struts 2222 b. The first driving member 223 and the second driving member 224 drive the first supporting rod 2221a and the second supporting rod 2222a to rotate, and the first supporting rod 2221a and the second supporting rod 2222a drive the first supporting rod 2221b and the second supporting rod 2222b to rotate, so that the length of the telescopic rod 222 in the direction along the sliding direction of the sliding seat 221 is extended, so that the telescopic rod 222 pushes the sliding seat 221 out of the housing 210. The increase in the number of the first supporting bars 2221 and the second supporting bars 2222 can increase the length of the telescopic bar 222 in the sliding direction along the sliding seat 221, so that the first driving member 223 and the second driving member 224 move a smaller distance, and the telescopic bar 222 increases a larger length in the sliding direction along the sliding seat 221, so that the pushing stroke of the sliding seat 221 is increased.

In an alternative embodiment, referring to fig. 5 and fig. 6, a guide groove 2132 is disposed on the bottom plate 213, and the guide groove 2132 is disposed between the first plate 215 and the second plate 216 and extends along a direction perpendicular to the moving direction of the sliding seat 221. The first driving member 223 and the second driving member 224 are slidably connected to the guide groove 2132, and the first driving member 223 and the second driving member 224 are not movable in the sliding direction of the sliding seat 221. Under the action of the controller 250, the first driving member 223 and the second driving member 224 approach each other along the guide groove 2132 from both ends of the guide groove 2132. Under the action of the controller 250, the first driving member 223 and the second driving member 224 move away from each other along the guide groove 2132 until the first driving member 223 and the second driving member 224 reach both ends of the guide groove 2132.

In some possible embodiments, referring to fig. 8 and 10, the housing includes a first plate 215 and a second plate 216 disposed opposite to each other. The first plate 215 and the second plate 216 are perpendicular to the bottom plate 213, and the direction of the first plate 215 pointing to the second plate 216 is perpendicular to the sliding direction of the sliding seat 221. The first driving member 223 is opposite to the first plate 215, and the second driving member 224 is opposite to the second plate 216. A first elastic member 227 is disposed between the first driving member 223 and the first plate 215, and a second elastic member 228 is disposed between the second driving member 224 and the second plate 216. When the first driving element 223 and the second driving element 224 approach each other, the first elastic element 227 and the second elastic element 228 are in a stretched state, so that when the first driving element 223 and the second driving element 224 are no longer subjected to a force of approaching each other, the first driving element 223 and the second driving element 224 can return to an initial position under the elastic force of the first elastic element 227 and the second elastic element 228, so that the telescopic element 222 changes from a collapsed state to an expanded state.

In some possible embodiments, referring to fig. 4, the functional components include a controller 250. The first driving member 223 is a permanent magnet, and the second driving member 224 is an electromagnetic coil. The controller 250 is electrically connected to the second driver 224. The controller 250 provides a first electrical signal to the second driving member 224. after the second driving member 224 receives the first electrical signal, the second driving member 224 may be magnetically different from the first driving member 223. A magnetic attraction force is generated between the first driving member 223 and the second driving member 224. The magnetic attraction force is larger than the elastic forces of the first elastic member 227 and the second elastic member 228, so that the second driving member 224 is close to the first driving member 223, and the telescopic member 222 is in a folded state to push the sliding seat 221 to slide out of the housing 210. The controller 250 stops providing the second driving member 224 or provides the second driving member 224 with a second electrical signal, and the second driving member 224 may be the same as the first driving member 223 or no magnetic force. The second driving member 224 and the first driving member 223 are no longer magnetically attracted or become magnetically repulsive. Under the elastic force of the first elastic member 227 and the second elastic member 228, the first driving member 223 and the second driving member 224 move away from each other to return the first driving member 223 and the second driving member 224 to the initial positions.

When the functional device 230 extends out of the housing 210, if the functional device 230 receives an impact force towards the housing 210, the impact force needs to overcome the magnetic attraction between the first driving member 223 and the second driving member 224 to restore the extensible member 222 to the open state, so that the magnetic attraction between the first driving member 223 and the second driving member 224 buffers the functional device 230, and the functional device 230 is prevented from being damaged due to rigid impact. Of course, in other embodiments, the first driving member 223 may be an electromagnetic coil, and the second driving member 224 may be a permanent magnet.

In some possible embodiments, referring to fig. 4 to 6, a sliding slot is formed at one end of the sliding seat 221 near the driving member 226. The extending direction of the sliding groove is perpendicular to the moving direction of the sliding seat 221. The slide slots include a first slide slot 260a and a second slide slot 260b arranged in a common line, the second end 2225 is slidably connected to the first slide slot 260a, and the fourth end 2227 is slidably connected to the second slide slot 260 b.

In some possible embodiments, referring to fig. 4 to 6, the first sliding groove 260a includes a first position-limiting end 261 and a second position-limiting end 262, which are oppositely disposed. The second sliding groove 260b includes a third position-limiting end 263 and a fourth position-limiting end 264, which are oppositely disposed. The second position-limiting end 262 is close to the third position-limiting end 263. When the second end 2225 and the fourth end 2227 are abutted to the first position-limiting end 261 and the fourth position-limiting end 264, the functional device 230 retracts into the housing 210, and the first position-limiting end 261 and the fourth position-limiting end 264 are used for limiting the position of the sliding seat 221 retracting into the housing 210. When the first end 2224 and the third end 2226 are abutted against the second position-limiting end 262 and the third position-limiting end 263, the functional device 230 extends out of the second position-limiting end 262 and the third position-limiting end 263 of the housing 210 to limit the position of the sliding seat 221 extending out of the housing 210.

In an alternative embodiment, referring to fig. 4 and 5, the bottom plate 213 is provided with guide rails 2131. The guide rail 2131 extends in a direction parallel to the sliding direction of the functional device 230. The sliding seat 221 is slidably connected to the guide rail 2131 and moves along the guide rail 2131. The guide rail 2131 is used for providing a direction for the sliding seat 221 to move towards or away from the through hole 217. Meanwhile, the guide rail 2131 can also ensure the placing direction of the sliding seat 221, so that the situation that the placing direction of the sliding seat 221 changes when the mobile terminal 100 is impacted, and therefore the sliding seat 221 cannot be aligned with the through hole 217, or the sliding seat 221 is prevented from being removed from the through hole 217, so that the guide rail 2131 can drive the sliding seat 221 to be smoothly removed from the through hole 217, and the removal resistance is reduced.

In some possible embodiments, referring to fig. 5, 6 and 11, the sliding seat 221 includes a receiving slot 225 for receiving the functional device 230, and further includes a blocking plate 2213 disposed in the receiving slot 225 and away from the driving member 226. When the functional device 230 retracts into the receiving cavity 211, the baffle 2213 covers the through hole 217 to limit the sliding seat 221 from continuing to retract into the receiving cavity 211.

In some possible embodiments, referring to fig. 11, the sliding seat 221 further includes a cover plate 2215 covering the receiving slot 225. The cover 2215 is provided with a signal penetration portion 2216, and the signal penetration portion 2216 is used for transmitting or receiving a signal through the functional device 230 when the functional device 230 extends out of the accommodating cavity 211.

Referring to fig. 12 in conjunction with fig. 1 to 11, the present application further provides a control method of a mobile terminal, where the control method of the mobile terminal is applied to the mobile terminal 100. The control method of the mobile terminal includes the following steps.

Step 101, the mobile terminal 100 receives an extension signal, and the mobile terminal 100 controls the first driving element 223 and the second driving element 224 to approach each other according to the extension signal, so as to drive the first end 2224 and the third end 2227 of the telescopic element 222 to approach each other, so as to drive the first support bar 2221 and the second support bar 2222 to rotate around the rotating shaft 2223, the second end 2225 is far away from the third end 2226, the fourth end 2227 is far away from the first end 2224, and the fourth end 2227 is close to the second end 2225, so that the telescopic element 222 is in a folded state, and the length of the telescopic element 222 in the sliding direction along the sliding seat 221 is increased, so that the telescopic element 222 drives the sliding seat 221 to slide to an extended state relative to the housing 210.

Step 102, the mobile terminal 100 receives a contraction signal, and the mobile terminal 100 controls the first driving element 223 and the second driving element 224 to move away from each other according to the contraction signal, so as to drive the first end 2224 and the third end 2227 of the telescopic element 222 to move away from each other, so as to drive the first support bar 2221 and the second support bar 2222 to rotate around the rotating shaft 2223, the second end 2225 is close to the third end 2226, the fourth end 2227 is close to the first end 2224, the fourth end 2227 is far from the second end 2225, and the protruding end 2223 is driven to move, so that the telescopic element 222 is in an expanded state, and the length of the telescopic element 222 in the sliding direction of the sliding seat 221 is reduced, so as to drive the sliding seat 221 to be contracted to a retracted state relative to the housing 210.

It can be understood that the mobile terminal 100 receives an extension signal or a retraction signal through a touch display, a receiver, a light sensing element, a flash, and the like, and controls the first driving member 223 and the second driving member 224 through the controller 250.

When the mobile terminal 100 falls, the mobile terminal 100 detects that an impact force applied to the sliding seat 221 in a sliding direction along the sliding seat 221 is greater than a preset value, the mobile terminal 100 may send a retraction signal to the controller 250, and the controller 250 receives the retraction signal and controls the first driving member 223 and the second driving member 224 to move away from each other according to the retraction signal. The first driving member 223 and the second driving member 224 drive the first end 2224 and the third end 2227 of the telescopic member 222 to be away from each other, so as to drive the first supporting rod 2221 and the second supporting rod 2222 to rotate around the rotating shaft 2223, and drive the protruding end 2223 to move, so that the telescopic member 222 is in an expanded state, and the length of the telescopic member 222 in the sliding direction along the sliding seat 221 is reduced, so as to drive the sliding seat 221 to be retracted to a retracted state relative to the housing 210.

According to the functional module, the mobile terminal and the control method thereof, the driving mechanism 220 and the functional device 230 are arranged in the shell 210, the driving mechanism 220 comprises the first driving piece 223, the second driving piece 224, the telescopic piece 222 and the sliding seat 221 for accommodating the functional device 230, the telescopic piece 222 is driven to open or close through the first driving piece 223 and the second driving piece 224, and the length of the telescopic piece 222 in the sliding direction of the sliding seat 221 is changed to drive the sliding seat 221 to extend out of or retract into the shell 210. When the functional device 230 is not needed, the functional device 230 is hidden inside the housing 210. When the functional device 230 needs to be used, the functional device 230 is driven to extend out of the housing 210 for use. Therefore, the functional device 230 does not occupy the position on the display screen 110 in the mobile terminal 100, thereby improving the screen occupation ratio of the mobile terminal 100, facilitating the operation and improving the user experience.

In addition, the sliding seat 221 is connected to the housing 210 through the telescopic member 222, so that when the mobile terminal 100 falls or the functional device 230 is impacted, an impact force can be counteracted, and the functional device 230 can be greatly protected, thereby increasing the reliability and the service life of the mobile terminal 100.
