Detailed Description

Reference is made to the accompanying drawings. The utility model provides a rotating shaft hinge with a two-section torque mechanism, which comprises a shaft 1, a first connecting structure 3, a second connecting structure 4 and a reed pipe; the first connecting structure 3 and the second connecting structure 4 are used for connecting the hinge to an applied electronic device, and are respectively connected to two coaxial components capable of rotating relatively on the electronic device. The shaft 1 is fixedly connected with a first connecting structure 3, the reed pipe is fixedly connected with a second connecting structure 4,

the shaft 1 is inserted through the reed pipe and is clamped by the reed pipe; the reed pipe comprises a first reed pipe 21 and a second reed pipe 22, and a cam block 5 is arranged in the second reed pipe 22; the inner wall of the second reed pipe 22 is provided with an axial groove 221. The cam block 5 is in the form of a key which is snap-fitted in the axial groove 221. As shown, the first spring tube 21 is on the inside in the axial direction and the second spring tube 22 is on the outside closer to the end of the shaft 1, facilitating the installation of the cam block 5.

The torque (marked by the first torque) provided by the first reed pipe 21 and the shaft section clamped by the first reed pipe is smaller than the torque required for stopping rotation at any time and positioning the current rotation angle at any time, and the torque range can be selected to be matched with the torque range opened by one hand, so that the rotation screen can be opened to the use angle by one hand when the screen is used.

The surface of the shaft section 12 clamped by the second reed pipe is provided with a cam surface which comprises a cam surface 121 corresponding to the using angle and a small-diameter section 122 at one end corresponding to the non-using angle. The cooperation between the cam surface and the cam block 5 provides a torque (when the shaft rotates to the arc surface 121 to cooperate with the cam block, see fig. 5, indicated as a second torque) within a corresponding use angle range, and the first torque is superimposed to be equal to or greater than a torque required to stop rotating at any time and position a current rotation angle at any time, and if the screen employs a touch screen, the superimposed torque of the second torque and the first torque is equal to or greater than a superimposed torque required to stop rotating at any time, position a current rotation angle at any time, and resist a touch pressure. The second torque is generally much higher than the first torque in the same angular range. The cam surface 121 may be an arc surface to output a constant second torque to the rotation shaft hinge, and the cam surface 121 may be a non-arc surface to output a variable torque.

In the remaining angular range, the torque provided by the cooperation between the cam surface and the cam block 5 (when the shaft is in the small diameter section 122 to cooperate with the cam block, see fig. 4, indicated by the third torque) and the first torque are superimposed to be less than the torque required to stop rotation at any time, to locate the current angle of rotation at any time, and may be selected to be in a torque range matching the one-handed opening.

When the requirement of the customer for the second section torque is changed, only the cam block needs to be replaced, and when the definition range of the using angle is changed, the circle center angle range of the cam surface 121 only needs to be properly adjusted, so that the cost is saved, and the convenience is realized.

In order to improve the compatibility for different requirements, the third torque is preferably much smaller than the first torque in the same angular range, or even zero, at rotational angles outside the angular range of use.

The range of the using angle is the range of the angle from the opening of the screen of the notebook computer to the visual angle of the notebook computer, and the using angle is generally 90-135 degrees.

In the description of the present invention, the directions or positional relationships indicated are the directions or positional relationships shown on the drawings, and are only for convenience of description and simplification of description, and it is not intended to indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus should not be construed as limiting the present invention.

The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art is in the field of the present invention, and all the changes or modifications are covered in the protection scope of the present invention.
