Description

foldable electronic device

This case is about an electronic device, and especially a foldable electronic device.

Flip laptops provide the ability to flip the screen at a large angle relative to the host, making the screen closer to the user. Flip laptops are often equipped with touch screens. When the user performs touch operations, the external force may be too heavy. As a result, the touch screen is tilted and difficult to use. The reason is that in the existing flip-type notebook computer, the torque module is only used to fix the unfolding angle between the touch screen and the host, and its torque is not enough to withstand the external force exerted by the user.

This application provides a foldable electronic device, in which the damping module and the pivot module are fitted with each other, so as to limit the rotation of the pivot module, provide a supporting external force when performing a touch operation on the second body, and also separate the damping module. With the pivot mod, let the pivot mod return to free rotation.

The foldable electronic device in this case includes a first body, a second body, A pivot module, a sliding seat and a damping module. The pivot module is pivotally connected to the first body and the second body. The sliding seat is movably arranged in the first body and has a first end portion protruding outside the first body. The damping module is arranged on the sliding seat and has a second end. When the first end is moved toward the pivot module by an external force, the sliding seat drives the second end of the damping module to engage with the pivot module. When the first end is subjected to an external force and moves toward the pivot module When moving in the direction of the sliding seat, the second end of the damping module is driven by the sliding seat to be separated from the pivot module.

Based on the above, in the foldable electronic device of this application, the first body and the second body are adapted to be relatively unfolded and switched to the locking mode. In the locking mode, the damping module is fitted into the pivot module to restrict the pivot module Do not rotate relative to the first body, and then lock the second body at a specific angle. When the user performs a touch operation on the second body, the damping module provides a supporting external force to prevent the second body from driving the pivot module to produce deflection. shift.

Further, the damping module and the pivot module can also be separated from each other, so that the damping module can release the restriction on the pivot module, and switch to the unlocking mode, so that the pivot module and the second body can resume free rotation, then The foldable electronic device in this case has the functions of angle locking and free rotation, which is beneficial to expand the use range of the foldable electronic device.

Specifically, when the first body 110a and the second body 120a are relatively unfolded by 0 to 315 degrees, the pivot module 130a generates a first stage of torsional force.

Referring to FIGS. 4B and 4D, when the first body 110a and the second body 120a are relatively unfolded by a second angle A2 (315 to 360 degrees) greater than the first angle A1, the stopper 136a pushes the cam 134a relative to the first rotating shaft 132a slides and compresses the return elastic member 135a. Specifically, when the first body 110a and the second body 120a are relatively unfolded by 315-360 degrees, the restoring elastic member 135a applies elastic force to the cam 134a, so that the cam 134a rubs against the stop portion 136a to generate a second stage of torsion.

Therefore, when the foldable electronic device 100A is unfolded to 315-360 degrees, it has a first stage of torsion force and a second stage of torsion force and is suitable for touch operation.

To sum up, in the foldable electronic device of this case, the first body and the second body are adapted to be relatively unfolded and switched to the locking mode. In the locking mode, the damping module is fitted into the pivot module to restrict the pivot. The module must not rotate relative to the first body, thereby locking the second body at a specific angle. When the user performs a touch operation on the second body, the damping module provides a supporting external force to prevent the second body from driving the pivot module produce an offset.

The damping module and the pivot module can also be separated from each other, so that the damping module is released from the restriction on the pivot module, and switched to unlock mode, so that the pivot module and the second body can resume free rotation, allowing the user to apply external force By adjusting the included angle of the second body relative to the first body, the foldable electronic device of the present application has the functions of angle locking and free rotation, which is beneficial to expand the use range of the foldable electronic device.
