The bottom of the sliding seat 20 is fixedly provided with two sliding blocks 22, and the two sliding blocks 22 slide separately Installed on the guide rail 21.

[0035] Such as Figure 2~7 As shown, the bottom of the sliding seat 20 is provided with a second groove 24, the bottom of the second groove 24 is fixedly provided with a nut 25, the nut 25 is threaded with a threaded rod 26, and the upper end of the threaded rod 26 penetrates The bottom of the second groove 24 extends into the inner cavity of the sliding seat 20, the top of the threaded rod 26 is fixedly provided with a mounting plate 27, the mounting plate 27 is located directly below the groove body 23, and the top of the mounting plate 27 is fixedly provided with The functional device 28 that can penetrate the trough 23, the functional device 28 is any one of a camera module, an iris recognition module, a face recognition module, a fingerprint recognition module, a flash, a photosensitive sensor, a receiver, and a microphone, The lower end of the threaded rod 26 extends into the second groove 24, and the bottom of the threaded rod 26 is fixedly provided with a knob 29, and the threaded rod 26 can move up or down linearly by turning the knob 29 forward and backward.

[0036] The working process of the present invention is as follows:

[0037] When the user wants to use the functional device 28 in the functional assembly 5 in the mobile terminal, the user turns the square head 9 back with his finger, so that the square head 9 rotates around the axis of the drive shaft from back to front. Direction as Figure 4 As shown by the middle arrow, the square head 9 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the cam 11 to rotate around the axis of the drive shaft. The rotation direction of the cam 11 is as follows figure 2 As shown by the middle arrow, the cam 11 drives the pin A12 and pulls the upper leg 16 of the torsion spring 6 to rotate. The torsion spring 6 is twisted and deformed. At the same time, the pin A12 drives the first link 13 to rotate, and the first link 13 drives the second link via the pin B14. The rod 15 rotates, and the second connecting rod 15 transmits the torque to the pin C31. The pin C31 drives the sliding seat 20 to move linearly to the right along the guide rail 21, and then the sliding seat 20 passes through the guide groove 4 and extends to the cavity 3 Externally, the extension of functional components is realized. When the iron block 18 rotates to touch the magnet 19 Figure 8 As shown, the square head 9 can no longer be rotated, and the functional assembly 5 no longer protrudes as Picture 9 As shown, at this time, the user can use the functional device, which realizes providing the user with a diverse experience. When the functional assembly 5 is to be retracted, the square head 9 can be reversely rotated to separate the iron block 18 from the magnet 19, and then the square head 9 is loosened. At this time, the cam 11 moves around the drive shaft under the restoring force of the torsion spring 6 The axis is reversed. The cam 11 drives the first link 13 to reverse, the first link 13 drives the second link 15 to reverse, and the second link 15 drives the sliding seat 20 along the guide rail 21 through the guide groove 4 and enters Into the cavity 3, thereby realizing the retracting of the functional components such as figure 2 Shown.

[0038] When the functional assembly 5 extends outward, the iron block 18 is adsorbed on the iron magnet 19, so that the sliding seat 20 can no longer move, so there is no need for the user to hold the square head 9 again, thus ensuring that the user has an idle hand to operate the display screen Or functional device 28, the mobile terminal not only facilitates user operations, but also improves the diversity of user experience. In addition, the mobile terminal also replaces the original use of bending springs to achieve the extension or retraction of the functional components, but uses the method of rotating the square head 9 to achieve the extension or retraction of the functional components, without damaging parts. This greatly extends the service life of the mobile terminal.

[0039] When the functional device 28 needs to be repaired, the worker only needs to extend the functional component 5 to the outside of the cavity 3, and then turn the knob 29. The knob 29 drives the threaded rod 26 to rotate, and the threaded rod 26 moves upward in a straight line, and then the functional device 28 passes upward through the trough body 23 and extends to the outside of the sliding seat 20 as Picture 10 As shown, at this time, the maintenance personnel can repair the functional device 28 externally. Compared with the traditional maintenance inside the sliding seat, the operation space during maintenance is increased, which not only facilitates the maintenance personnel to repair the functional device, but also shortens Maintenance time improves maintenance efficiency.
