The double-shaft hinge comprises a first shaft 1 and a second shaft 2 which are arranged in parallel, wherein the first shaft 1 is provided with a first torque mechanism, the second shaft 2 is provided with a second torque mechanism, and a synchronous reverse rotation connecting mechanism is connected between the first shaft 1 and the second shaft 2, so that the first shaft 1 and the second shaft 2 synchronously and reversely rotate.
The first torque mechanism and the second torque mechanism both adopt cam control structures. The first torque mechanism comprises a movable cam 11 and a static cam 12 which are sleeved on the first shaft 1 and are matched with each other, the movable cam 11 and the static cam 12 are pressed by a plurality of disc spring pieces 13 sleeved on the first shaft, the movable cam 11 can slide relative to the first shaft 1 but cannot rotate relative to the first shaft 1, the first shaft 1 can rotate relative to the static cam 12, the disc spring pieces 13 are pre-compressed through a nut 14 and a gasket, and the nut 14 is in threaded connection with the end part of the first shaft 1. The second torque mechanism comprises a movable cam 21 and a static cam 22 which are sleeved on the second shaft 2 and are matched with each other, the movable cam 21 and the static cam 22 are pressed by a plurality of disc-shaped spring pieces 23 sleeved on the second shaft, the movable cam 21 can slide relative to the second shaft 2 but cannot rotate relative to the second shaft 2, the second shaft 2 can rotate relative to the static cam 22, the plurality of disc-shaped spring pieces 23 are pre-compressed through a nut 24 and a gasket, and the nut 24 is in threaded connection with the end part of the second shaft 2.
When the mobile electronic terminal is in the use angle range, the sum of the output torque of the second torque mechanism and the output torque of the first torque mechanism satisfies the torque required for stopping rotating and positioning the current rotation angle at any time, that is, after the screen (touch screen) is opened to a normal use angle, for example, when the screen (touch screen) is close to 110 ° (that is, when the first shaft 1 and the second shaft 2 both rotate close to 55 °), the screen is close to fully opened (in this embodiment, the mobile electronic terminal opens the notebook computer for 360 ° full angle, and when the first shaft 1 and the second shaft 2 both rotate for 170 °), in the angle range, the screen can be rotated to any angle, and the current angle can be maintained by means of the superposition of the output torques of the first torque mechanism and the second torque mechanism, even during touch operation.
