Description

Hub and electronic device using it

This creation relates to a hinge device and an electronic device using it, and in particular to a hinge device having a torsion generating member using a friction plate and an electronic device using it.

An existing electronic device includes two bodies and a hinge device, wherein the hinge device includes a rotating shaft and a support frame pivotally connected to the rotating shaft. The pivot is connected to one body and the support frame is connected to the other body, the hinge device provides two bodies that can be relatively expanded and closed. This electronic device is, for example, a notebook computer. One of the two bodies (also called the upper body) is provided with a screen, and the other body (also called the lower body) is provided with components such as a motherboard, a keyboard, and a hard disk. In order to generate torsion so that the two bodies can be freely stagnated at a preset angle or position when they are expanded and closed, the hinge must be provided with a torsion generating element.

An existing torsion generating member includes a friction plate, an elastic piece, a concave cam and a nut sleeved on a rotating shaft, wherein the concave cam is connected to a supporting frame. This torsion generator uses the stack of shrapnel to generate axial thrust, pushes the friction plate to cause friction to generate torque, and uses the locking degree of the nut to adjust the torque. In addition, it also uses the matching between the concave cams to make the hub automatically close (auto lock) function. The so-called auto-closing function means that when the angle between the two bodies of the electronic device is closed to a specific angle (for example, 30 degrees), the torque will decrease, allowing the upper body to fall freely onto the lower body.

However, the torsion generating member is limited by the structure, for example, the concave cam must be connected to the support frame, so that the space where the friction plates can be sleeved is limited, and more friction plates cannot be sleeved, and therefore, greater torque cannot be generated. If the torsion generating member wants to generate more torsion, it can only increase the size of the friction plate, but this will increase the size of the hub and is not suitable for thinner and thinner electronic devices.

The purpose of this creation is to propose a hub device and an electronic device using it. The friction plate in the torsion generating member uses a new design. The number of friction plates can be increased as needed to generate greater torque. In addition, the concave cam is designed to be connected to the adjacent The friction plate makes the space where the friction plate can be sleeved is not limited, and more friction plates can be sleeved to generate greater torque.

The second friction member is sleeved and clamped to the rotating shaft, and the second friction member has a second stop part; the second stop part cooperates with the first stop part to restrict the second friction part relative to the first friction part The rotatable angle of, thereby limiting the rotatable angle of the shaft relative to the support frame.

In an embodiment of the present creation, when the number of friction components is multiple, the first friction component also has a third butting portion, and the third butting portion and the second butting portion are matched to make the friction components of two adjacent friction components The two first friction members are connected to each other.
