The following is a detailed description of the implementation details of the mobile terminal 100 provided in the embodiments of the present invention, and the following is only provided for the convenience of understanding and is not necessary for implementing the present invention.

In this embodiment, as shown in fig. 4, the rotating shaft 21 includes: a columnar case 211 extending in the direction of the long side of the mobile phone body 1; the bearing 212 penetrates through the cylindrical shell 211 and is abutted to the mobile phone body 1, two ends of the bearing 212 protrude out of the cylindrical shell 211, the number of the rotating rods 22 is two, the rotating rods are respectively in transmission connection with two ends of the bearing 212, and the driving device 4 is in transmission connection with the bearing 212; and a damper spring 213 disposed between the bearing 212 and the cylindrical housing 211. It can be understood that, because the rotating shaft 21 is disposed in the groove 20, and the rotating shaft 21 rotates ceaselessly when the rotating bin 23 moves, so that friction occurs between the rotating shaft 21 and the groove, the casing of the rotating shaft 21 is designed into a cylindrical shape, so that the friction between the rotating shaft 21 and the groove 20 is rolling friction, thereby effectively avoiding the abrasion between the groove 20 and the rotating shaft 21, and avoiding the situation that the rotating bin 23 cannot normally move to a target position due to the overlarge friction force between the rotating shaft 21 and the groove 20.

A stopper portion 214 that extends toward the bearing 212 and abuts against the bearing 212 is provided on the inner wall of the cylindrical housing 211. The limiting part 214 is arranged to stably fix the bearing 212 in the cylindrical housing 211, so that the situation that the bearing 212 does not drive the cylindrical housing 211 to synchronously rotate when rotating due to unstable fixation between the bearing 212 and the cylindrical housing 211 is avoided, and the reliability of the mobile terminal 100 is improved. It should be noted that the limiting portion 214 in the present embodiment is disposed at the center of the cylindrical housing 211, so that the bearing 212 is uniformly stressed during the rotation process.

Specifically, the damping springs 213 are provided in plural numbers, and the plural damping springs 213 are provided on both sides of the stopper portion 214 in the axial direction of the bearing 212. It can be understood that the deformation direction of the damping spring 213 in this embodiment is the radial direction of the bearing 212, and the vibration generated by the rotating shaft 21 during the rotation process is effectively reduced by arranging the damping spring 213 on both sides of the bearing 212.

Preferably, the damping springs 213 on both sides of the limiting portion 214 are equal in number, and the damping springs 213 on the same side of the limiting portion 214 are uniformly arranged at equal intervals in the axial direction of the bearing 212. Preferably, the damping spring 213 is a coil spring, and an included angle between two adjacent coil springs located on the same side of the limiting portion 214 in the axial direction is 90 °. That is, four coil springs are provided on each side of the stopper portion.

In the present embodiment, the gear set 43 includes a first gear 431 fixedly connected to the first guide rod 42, a bevel gear 432 drivingly connected to the first gear 431, and a second gear 433 drivingly connected to the bevel gear 432, and the second gear 433 is fixedly connected to the second guide rod 44. When the rotating device 2 needs to rotate, the motor 41 located in the vertical direction (i.e. the long side direction of the mobile phone body 1) rotates to rotate the first guide rod 42 which is in transmission connection with the motor and also located in the vertical direction, the first guide rod 42 drives the first gear 431 in transmission connection with the first guide rod to rotate, the first gear 431 drives the bevel gear 432 to rotate and changes the transmission direction by 90 degrees through the bevel gear 432, so that the bevel gear 432 drives the second guide rod 44 located in the horizontal direction (i.e. the short side direction of the mobile phone body 1) to rotate, and then the bearing 212 is driven to rotate, thereby rotating the rotating shaft 21.

It should be noted that the back of the mobile phone body 1 is fixedly provided with a first rear camera (not shown), one side of the rotary bin 23 adjacent to the front is provided with the front device 3, and one side of the rotary bin 23 adjacent to the back 10 is provided with a second rear camera (not shown). When the rotary bin 23 is in a hidden state, the mobile phone with two cameras is used, and after the rotary bin 23 is opened, the function of shooting a three-dimensional video is increased due to the fact that the linear distance between the two rear cameras is increased. It is understood that the front device 3 faces the front side of the handset body 1 and the rear camera faces the rear side 10, regardless of whether the rotary bin 23 is received in the recess 20.

As shown in fig. 7, the mobile terminal further includes a signal cable (not shown) and a power supply (not shown), the motor connection system is disposed in the left space of the whole machine (back), and the signal cable and the power supply pass through the rotating rod 22 through the right guide rod (i.e., the rotating rod 22 on the right side), so as to connect the inside of the whole machine with the rotating cabin of the whole machine.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
