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.

Referring to fig. 1, 4 to 6, fig. 4 and 6 are schematic structural views of a functional assembly provided in an embodiment of the present application in two different states of extending out of a housing and retracting into the housing. 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 is slidably retractable in the receiving cavity 211.

Referring to fig. 5 to 9, the functional assembly 200 further includes a sliding seat 221, the functional device 230 is accommodated in the sliding seat 221, and the sliding seat 221 moves to enable the functional device 230 to be retracted into the accommodating cavity 211 or at least partially extend out of the accommodating cavity 211. The driving mechanism 220 includes a first roller 222, a second roller 223 and a driving member 224 (see fig. 7 and 8). Referring to fig. 9, the sliding seat 221 has a receiving groove 225, and the receiving groove 225 is used for receiving the functional device 230. The sliding seat 221 includes a first side wall 2211 and a second side wall 2212 opposite to each other, and the first side wall 2211 and the second side wall 2212 are parallel to the telescopic direction of the sliding seat 221. Referring to fig. 5 and 6, the first roller 222 and the second roller 223 abut against the first side wall 2211 and the second side wall 2212, respectively. The driving element 224 is configured to drive the first roller 222 and the second roller 223 to roll, and the rolling processes of the first roller 222 and the second roller 223 generate rolling friction forces on the first side wall 2211 and the second side wall 2212, respectively, and the rolling friction forces drive the sliding seat 221 to move relative to the first roller 222 and the second roller 223, so that the sliding seat 221 extends out of or retracts into the accommodating cavity 211, and the sliding seat 221 drives the functional device 230 to extend out of or retract into the accommodating cavity 211, thereby realizing diversification of use of the mobile terminal 100 and improving user experience.

By arranging the driving mechanism 220, the functional device 230 and the sliding seat 221 in the housing 210, the functional device 230 is slidably and telescopically inserted into the accommodating cavity 211 of the housing 210, the sliding seat 221 accommodates the functional device 230, the first roller 222 and the second roller 223 of the driving mechanism 220 abut against two opposite side walls of the sliding seat 221, the driving member 224 of the driving mechanism 220 drives the first roller 222 and the second roller 223 to roll, so as to generate a rolling friction force, and the rolling friction force drives the functional device 230 to extend out of or retract into the accommodating cavity 211. When the functional device 230 is not needed to be used, the driving mechanism 220 hides the functional device 230 inside the housing 210, and when the functional device 230 is needed to be used, the driving mechanism 220 drives the functional device 230 to extend out of the housing 210 for use, so that the use diversification of the mobile terminal 100 is realized, and the user experience is improved.

In this embodiment, a pair of rollers is disposed on two opposite sides of the sliding seat 221. The driving member 224 drives a pair of rollers to rotate synchronously, so that rolling friction forces in the same direction are generated on both sides of the sliding seat 221, and the rolling friction forces act on both sides of the sliding seat 221 to push the sliding seat 221 to move smoothly. In other embodiments, the number of the rollers may also be two pairs, three pairs, five pairs, and so on.

Optionally, the first roller 222 and the second roller 223 may have the same size and shape, so that the first roller 222 and the second roller 223 generate rolling friction forces with the same direction and the same size on two sides of the sliding seat, and thus the thrust forces of the first roller 222 and the second roller 223 on two sides of the sliding seat 221 are the same.

In this embodiment, referring to fig. 7 and 8, the sliding seat 221 is sandwiched between the first roller 222 and the second roller 223, and the sliding seat 221 may be in a state of being slightly pressed by the first roller 222 and the second roller 223, so as to prevent the first roller 222 and the second roller 223 from idling and being unable to transmit the driving force of the driving member 224 to the sliding seat 221.

In this embodiment, the sliding seat 221 and the housing 210 are connected through the first roller 222 and the second roller 223, and the connection manner between the pair of side walls of the sliding seat 221 and the first roller 222 and the second roller 223 is a surface-to-surface contact connection, rather than a connection manner of mutual embedding or mutual engagement. When the mobile terminal 100 falls or the sliding seat 221 is impacted along the sliding direction of the sliding seat 221, the sliding seat 221 may be impacted by a larger impact force at the moment, and when the impact force is greater than the maximum static friction force between the first roller 222, the second roller 223 and the sliding seat 221, the first roller 222, the second roller 223 and the sliding seat 221 may move relatively, and on one hand, the process of the relative movement may counteract part of the impact force to reduce the impact force from the 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 process of the relative movement 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 roller, 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 and covers the accommodating 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. The functional device 230 does not occupy the position on the display screen 240 in the mobile terminal 100, so that the processing procedures of hollowing or punching the display screen 240 and the display screen 240 are reduced, and the functional device 230 does not occupy the position on the display area 241 in the mobile terminal 100, so that the screen occupation ratio of the mobile terminal 100 is improved, the operation is convenient, and the user experience is improved.

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.

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 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 231 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. When the functional device 230 is retracted into the receiving cavity 211, the display area 241 of the display screen 240 partially or completely covers the functional device 230.

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.

In other embodiments, the first and second belts 2242 and 2246 may be replaced with a driving rope, a driving chain, a gear, or the like.

Referring to fig. 10, with reference to fig. 1 to fig. 9, the present application further provides a method for controlling a mobile terminal, which is used for the mobile terminal 100, and the method for controlling the mobile terminal includes:

step 101, the mobile terminal 100 receives a stretching signal, and the mobile terminal 100 controls the first scroll wheel 222 and the second scroll wheel 223 to respectively roll along a first direction and a second direction according to the stretching signal, wherein the first direction is a clockwise direction or a counterclockwise direction, and the second direction is opposite to the first direction. The first roller 222 and the second roller 223 generate friction acting forces pointing to the outside of the housing on the two opposite sides of the sliding seat 221 during rolling, and the friction acting forces drive the sliding seat 231 to move, so that the functional device 230 slides to an extended state relative to the housing 210.

Step 102, the mobile terminal 100 receives a contraction signal, the mobile terminal 100 controls the first roller 222 and the second roller 223 to roll along the second direction and the first direction respectively according to the contraction signal, the first roller 222 and the second roller 223 generate friction acting force pointing to the inside of the housing 210 to the two opposite sides of the sliding seat 221 in the rolling process, and the friction acting force drives the sliding seat 231 to move, so that the functional device 230 contracts to a retracted state relative to the housing 210.

It is understood that the mobile terminal 100 receives the extension signal or the contraction signal through a touch display, a receiver, a light sensing element, a flash, and the like, and controls the 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 along the sliding seat 221 is greater than a preset value, the mobile terminal 100 may send a contraction signal to the controller 250, the controller 250 receives the contraction signal, and controls the first roller 222 and the second roller 223 to roll along the second direction and the first direction respectively according to the contraction signal, and the first roller 222 and the second roller 223 generate friction acting forces pointing into the housing 210 to opposite sides of the sliding seat 221 during the rolling process, and the friction acting forces drive the sliding seat 231 to move, so that the functional device 230 contracts to a retracted state relative to the housing 210.

By arranging the driving mechanism 220, the functional device 230 and the sliding seat 221 in the housing 210, the driving mechanism 220 includes a first roller 222, a second roller 223 and a driving member 224, the driving member 224 drives the first roller 221 and the second roller 223 to roll, and the first roller 221 and the second roller 223 generate a friction force with the sliding seat 221 during the rolling process, and the friction force drives the sliding seat 221 to extend out of or retract into the housing 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 first roller 222 and the second roller 223, 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 can be greatly protected, thereby increasing the reliability and the service life of the mobile terminal 100.
