As shown in fig. 1 and 2, the pressure type rotating shaft includes a rotating shaft base 1 and a fixed shaft 2, the fixed shaft 2 is mounted on the rotating shaft base 1; the rotating shaft base 1 is provided with a mounting hole 11; one end of the fixed shaft 2 passes through the mounting hole 11, and the other end is engaged with the mounting hole 11.

After the rotating assembly 3 rotates a predetermined first angle relative to the rotating shaft base 1, the limiting member 4 is pressed by the rotating assembly 3 and abuts against the elastic member 5. The first angle refers to a demarcation angle at which the user enters a stage of adjusting the pitch angle of the electronic device after rotating the initial angle.

Specifically, when a user rotates the electronic device, the rotating assembly 3 is driven to rotate relative to the fixed shaft 2, and after the rotating assembly 3 rotates by a first angle, the limiting member 4 is extruded by the rotating assembly 3 to abut against the elastic member 5, so that the elastic member 5 is compressed; furthermore, one end of the elastic element 5 is fixed on the fixed shaft 2, and the elastic element 5 applies pressure to the limiting element 4, so that the friction force between the limiting element 4 and the rotating assembly 3 is increased, and the torque force of the pressure type rotating shaft is increased; when the user rotates electronic equipment, the pressure type rotating shaft improves the torque required by rotation by increasing pressure, the effect of changing hand feeling in the rotating process is realized, and the use experience of the user is improved. Illustratively, for a notebook computer flip scene, a user can initially unscrew the screen with small force, then the torsion of the pressure type rotating shaft is increased, the rotating angle of the screen can be better self-maintained, the shaking of the screen is effectively reduced, the user can conveniently adjust the pitch angle of the screen, and the user experience in the process of opening and closing the notebook computer is optimized.

In a specific implementation manner, as shown in fig. 2 to 4, a first pressing protrusion 311 with an opening 312 is protruded from one side of the rotating assembly 3 facing the limiting member 4; the position of the limiting member 4 corresponding to the opening 312 is protruded with a second extrusion protrusion 41. The first pressing protrusion 311 is protruded on a wall surface of the engaging block 31 facing the limiting member 4.

Illustratively, the second pressing protrusion 41 is received in the opening 312 when the electronic device is not rotated; after the rotating assembly 3 rotates a predetermined first angle relative to the rotating shaft base 1, the first extruding protrusion 311 abuts against the second extruding protrusion 41 to extrude the limiting member 4 toward the direction close to the elastic member 5, so as to finally improve the friction between the limiting member 4 and the rotating assembly 3, thereby improving the torque of the pressure type rotating shaft.

Further, a plurality of grooves are formed on the wall surface of the first extrusion protrusion 311 facing the limiting member 4 and the wall surface of the second extrusion protrusion 41 facing the rotating assembly 3. The second pressing protrusion 41 can slide out of the opening 312 onto the first pressing protrusion 311.

The rotating assembly 3 further comprises a transmission shaft 33; one end of the transmission shaft 33 is fixedly connected with the movable end of the reset component 7, and the other end of the transmission shaft 33 is fixedly connected with the rotating block 32.

Specifically, the reset assembly 7 includes a mounting seat 71 provided on the rotating shaft seat 1; an electromagnetic clutch and a driving motor are installed in the mount 71.

One end of the electromagnetic clutch is fixedly connected with a rotor of the driving motor, and the other end of the electromagnetic clutch is fixedly connected with the transmission shaft 33. The function of the pressure type rotating shaft is expanded, and the torque of the pressure type rotating shaft can be conveniently adjusted by the electronic equipment; for example, when the pressure type rotating shaft normally operates, the electromagnetic clutch is not electrified; when the pressure type rotating shaft needs to be reset, the electromagnetic clutch is electrified, so that the rotating block 32 is fixedly connected with the rotor of the driving motor, and then the driving motor drives the rotating block 32 to rotate, so that the rotating block 32 is reset.

In particular, the elastic member 5 is a spring washer. It should be added that the elastic member 5 may also be a component with elasticity, such as a sheet spring, a pressure spring, or the like.

Further, the pressure type rotating shaft further comprises a locking member 8 for preventing the elastic member 5 from slipping out of the fixed shaft 2; the locking piece 8 is fixedly connected with the fixed shaft 2.
