Description

M442683 V. New description: [New technical field] [0001] This creation relates to a multi-directional rotary hinge, especially a light and thin multi-directional rotary hinge. [Previous Technology] [0002] A clamshell electronic device (such as a notebook computer, mobile multimedia, etc.) is provided with a hinge device in the display and keyboard module of the electronic device, and provides a display device when the keyboard module is opened. Torque needed. However, the demand for clamshell electronic devices is no longer just that the electronic device can be opened and closed to reduce the storage volume. Some studies have shown that in addition to the hope that the clamshell electronic device can be opened and closed, it is more desirable for the electronic device. The display can be rotated at an appropriate angle relative to the keyboard module.

[0003] Therefore, a multi-directional rotating hinge is available, and its structure is disclosed in the Patent No. M382700 and M366283 of the Republic of China. The hinge is formed by a rotating base that can be rotated relative to an assembled plate and two separate extensions. The arm on the rotating base rotates the display of the electronic device relative to the keyboard module. However, the rotary base of the rotary hinge and the arm thereof are integrally formed by die-casting, and in order to perform die-casting smoothly, a base material of a rotary seat is generally selected to have a relatively rigid material such as zinc. However, in practice, the rotating base and its arm bear the weight of the display, so that the frictional force of the rotating seat relative to the assembly plate is increased, so that the softer material is easy to wear and is not suitable for long-term use. Therefore, the multi-directional rotating hinge now has a friction plate between the rotating base and the assembled plate, and the friction plate is used to slow the wear of the rotating seat, but the setting of the friction plate causes the overall thickness of the hinge to increase, and It is not conducive to the thinning of the clamshell electronic device 1012048791-0 page 3 / 19 pages M442683. [0004] In order to solve the above problem of easy wear, a relatively rigid material is used as a substrate to manufacture the rotating base. In addition to the fact that the rotary seat cannot be processed by die casting technology, the design of the die casting is limited in thickness. If direct milling machine processing produces considerable waste in manufacturing, it creates a cost burden. [New content]

[0005] The main purpose of this creation is to overcome the problem that the multi-directional rotating hinge needs to use the friction plate to reduce the wear of the rotating seat, but the overall thickness is increased. Another object of the present invention is to provide a hinge structure that can reduce manufacturing waste.

In order to achieve the above object, the present invention provides a thinned multi-directional rotary hinge comprising an assembly plate, a rotating base having a rotational stroke relative to the assembled plate, and a carrying arm disposed on the rotating base. The assembly board includes a through hole and at least one limiting portion, and the rotating base includes a through portion penetrating the through hole, and a contact relationship with the limiting portion in the rotating stroke to form a limit relationship a protruding portion and a bridge portion disposed on the other side of the through portion, wherein the carrying arm includes an assembly portion coupled to the bridge portion for mounting the carrying arm on the rotating seat, and at least one disposed on the carrying portion The pivoting structure at the end of the arm. In an embodiment, the thinned multi-directional rotary hinge further includes a positioning piece disposed on the other side of the assembly board where the rotating seat is disposed to position the rotating seat on the assembly board. And further, the assembled board may include 101204879, 0, 4th, 19th, M442683, a positioning chute opposite to the other side of the rotating base, and the positioning piece may include a rotation against the positioning chute. Positioning convex part subject to transient limit. In one embodiment, the thinned multi-directional rotary hinge further includes a positioning piece disposed on the other side of the assembly board where the rotating seat is disposed to position the rotating seat on the assembly board. Furthermore, the rotating base may include a through hole communicating with the through portion and the bridge portion, and the positioning piece may include a through hole communicating with the through hole. In addition, the carrying arm may include a through hole communicating with the through hole. [0010] In an embodiment, the rotating seat is composed of a group consisting of iron, iron alloy, steel, steel alloy and plastic steel. One made. [0011] In one embodiment, the carrier arm is made of one of a group consisting of iron, iron alloy, steel, steel alloy, and plastic steel.

[0012] In summary, the rotating seat of the thinned multi-directional rotary hinge and the carrying arm are divided into two components, so that the rotating seat and the carrying arm can be made of a material with a relatively rigid rigidity, compared with With the conventional rotary hinge, the creation of the friction plate can be omitted, and the overall thickness of the thin multi-directional rotary hinge can be thinned, which contributes to the thinning of the clamshell electronic device. In addition, the rotating seat made of a hard and rigid material can overcome the problem that the rotating seat is made of zinc material, which causes the rotating seat to be easily worn. [Embodiment] [0013] The detailed description and technical content of the present invention will now be described with reference to the following figures: [0014] Please refer to FIG. 1 to FIG. 3, which are respectively for creating a thinned multi-directional rotary hinge 1012151# No. Delete 1 Page 5 / Total 19 Page 1012048791-0 M442683
