Description

Two-axis synchronous double-pack pivot

technical field

The utility model relates to a double-shaft co-moving double-wrapped pivot device, which generates torsion when the main shaft rotates through a preset double-wrapped shaft sleeve, and a synchronous mechanism is set in the inner space of the double-wrapped shaft sleeve to generate the double-shaft Synchronized linkage.

Background technique

Existing electronic devices such as notebook computers are generally provided with a host system end and a liquid crystal display screen end that can be opened. When in use, the liquid crystal display screen of the upper cover can be opened with the rotation controller as the action axis for operation, or the two can be relatively closed in reverse when not in use. In order to conveniently open the upper cover of the display screen to a fixed angle and turn the entire notebook computer into a flat form, most of the existing notebook computers use a dual-axis co-moving torque pivot to position the opening angle and turn it over at a large angle. The main body of the fold.

In order to position the upper cover of the display screen after it is opened to a fixed point angle, a torsion mechanism must be installed on this type of dual-axis co-moving torque pivot, so that the upper cover can be positioned at the desired position with torque when the two axes are actuated. angle. The torsion mechanism is generally installed at one end of the two shafts, and the torsion mechanism is stressed by the rotation of the two shafts to produce the desired positioning capability. However, in addition to having more and more complicated components, such a conventional torsion mechanism also has relatively high assembly and operating costs.

At the same time, the structure of the existing two-axis pivot device mainly has a first rotating shaft that rotates together with the display screen of the upper cover, and a second rotating shaft that rotates together with the host system end. However, when the existing two-axis pivots are opened at a relatively large angle, or when the display end and the system end are folded over 360° to overlap each other, one of the axes is usually rotated to a specific angle first, and then Switching to another axis of rotation, the synchronous turning mechanism of the entire display end and the system end is quite complicated, and the turning action of the display end and the system end is slow and not smooth.

And in this kind of double-axis pivoting device, it is necessary to carry out the rotation action conversion between the two axes, which usually involves the installation of a complicated rotation transformation mechanism between the two axes, because the two-axis rotation controller has many components and requires Installed in a narrow and limited space, the use of a complicated rotation transformation mechanism will not be conducive to the thinning of the entire electronic device.
