Description

Hinge structure and its portable device

【Technical field】

The utility model relates to a hinge structure and a portable device thereof, in particular to a hinge structure for use with a cable and a portable device thereof.

【Background technique】

Hinges are mainly installed between two objects so that the two objects can pivot at a certain angle (pivotal rotation), so they are usually used in portable electronic devices such as notebook computers, mobile phones, and electronic dictionaries. That is to say, these portable electronic devices are consumer electronic products respectively having a main body and a cover. The upper cover with the screen is connected to the hinge of the main body, so that the upper cover can be opened or closed relative to the main body.

In the conventional technology, the upper cover and the electronic device of the main body are only connected by a hinge, and the wire must be connected from the main board of the main body to the screen of the upper cover through the hinge, so that the signal can be transmitted to the screen. However, as the size of electronic devices continues to be thinner and lighter, how to prevent electronic circuits from being hindered by hinges and affect the wiring pattern and aesthetics is testing the design capabilities of the industry. Also, because the development trend of electronic products is towards lightness, thinness and shortness, it is quite difficult to design the serial connection of the electronic circuit between the upper cover and the main body. That is to say, when the overall structure of electronic devices is getting smaller, the hinge structure is also shrinking, so how to lay out the wire path to prevent the electronic circuit from being wound on the hinge, or to avoid damage to the circuit or improper operation of the hinge, etc. These problems are testing the wisdom of relevant industry players.

The known technology, such as US Publication No. 2011/0242756 "Computer with Hollow Hinge", discloses a design in which electronic wires pass through the hinge. For example, the hollow pivot of US Publication No. 2011/0242756 includes a fixed bracket, a grabbing portion, a friction portion and a pivoting bracket. The grasping part is formed integrally with the fixed seat with several positioning holes formed at the other end, so that the fixed support has better rigidity. The friction part is rotatably sheathed on the grabbing part to form a torsion force. A pivoting support frame forming a plurality of positioning holes extends on one side of the friction part for fixing with the upper cover (not shown) of the electronic product. The fixed seat is fixedly connected with the body (not shown in the figure) of the electronic product. In addition, a pivot hole is formed in the grabbing portion for passing one or more electronic wires (not shown).

However, in the actual assembly process, the electronic wire (cable) must be passed through the hollow pivot first, and then the connector (not shown) and the electronic wire are welded. Due to the hinge passing through the wire, in addition to the inconvenience caused in the process of welding the connector, it also makes the welding automation difficult and increases the man-hours and other costs. In view of this, the utility model artificially solves the problem that the conventional hinges and electronic wires are designed by different manufacturers and is difficult to assemble, and specially designs an integrated design scheme to facilitate the miniaturization and light weight of portable electronic products direction development.
