Description

      The present invention relates to a hinge and an electronic device including the hinge, and more particularly to a hinge provided between a cover and a base of the electronic device and having a shaft that slides while the cover is rotating.

8 and 9, conventional electronic devices such as mobile phones and notebook computers have bases 90 and 90A, covers 92 and 92A, conventional hinges 91 and 91A, and lids 93 and 93A. The conventional hinges 91 and 91A are provided between the bases 90 and 90A and the covers 92 and 92A so that the covers 92 and 92A can be rotated with respect to the bases 90 and 90A. The lids 93 and 93A are attached to the bases 90 and 90A and cover the conventional hinges 91 and 91A to decorate the conventional electronic apparatus.

  When the covers 92 and 92A rotate with respect to the bases 90 and 90A, the lids 93 and 93A come into contact with the ends of the covers 92 and 92A to prevent the covers 92 and 92A from rotating. In order to eliminate the contact between the covers 92 and 92A and the lids 93 and 93A, there are the following two conventional methods.

  FIG. 8 shows one conventional electronic device. The end of the lid 93 close to the cover 92 has an inclined surface 94. Since the cover 92 rotates along the inclined surface 94, the lid 93 does not prevent the cover 92 from rotating. However, the inclined surface 94 impairs the overall appearance of the conventional electronic device.

  FIG. 9 shows another conventional electronic device. A gap is formed between the cover 92A and the lid 93A. Accordingly, the cover 92A is far from the lid 93A when it rotates. However, this gap not only impairs the appearance of the conventional electronic device, but also increases the size of the conventional electronic device.

  Therefore, the above conventional method for eliminating the contact between the cover 92, 92A and the lid 93, 93A impairs the appearance of the conventional electronic device and increases the size of the conventional electronic device. Deteriorating the appearance of a conventional electronic device and increasing the size of the conventional electronic device will counter market demands.

  In order to overcome these drawbacks, the present invention provides a hinge and an electronic device including the hinge that can alleviate or eliminate the above-mentioned problems.

A main object of the present invention is to provide a hinge and an electronic device including the hinge that can lift the cover as desired.

  Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The hinge of the present invention is provided between the cover and the base of the electronic device. This lid covers the hinge and is securely attached to the base. The hinge has an arcuate curved surface and a rotation axis. When the cover is rotated at an angle, the cover is selectively moved away from the lid when the rotating shaft comes into contact with the arched curved surface and lifts the cover. Therefore, the shape of the electronic device is not damaged, and the cover does not interfere with the lid.

The hinge of the present invention and the electronic device including the hinge smoothly lift up the cover when the cover is rotated at an angle. Therefore, the shape of the electronic device does not impair the appearance, and the cover does not interfere with the lid. Furthermore, the above-described electronic device can be made into a small and compact size, and the cover can be smoothly rotated to have a very beautiful shape.

3 to 5, the electronic apparatus according to the present invention includes a cover 40, a base 50, the above-described hinge and lid 60. The cover 40 is pivotally attached to the second tilt bracket 32. The attachment end 222 of the rotating shaft 22 is securely connected to the cover 40 or the rotating bracket 33 is securely attached to the cover 40. The first and second tilt brackets 31 and 32 are securely attached to the base 50. The lid 60 covers the hinge as described above and is securely attached to the base 50.

In FIGS. 6 a to 7 c, the cover 40 is pivotally attached to the base 50. The cover 40 is pivotally attached to the first and second tilt brackets 31 and 32 while holding the rotating shaft 22 and the central frame 11. When the tip 221 of the rotating shaft 22 contacts the arch-shaped curved surface 34, the rotating shaft 22 slides in the direction B as shown in FIGS. 6b and 7b to lift up the cover 40. Since the cover 40 is separated from the lid 60, the cover 40 does not interfere with the lid 60 even if it is rotated.

When the rotating shaft 22 slides in the B direction, the pin 24 slides in the groove 211. The pin 24 presses the pressing washer 224 to press the elastic member 23. When the cover 40 is continuously rotated, the tip 221 of the rotating shaft 22 is separated from the arch surface 34, and the force pushing the rotating shaft 22 slides in the B direction and is separated. The elastic member 23 presses the pressing washer 224 and presses the pin 24 to slide. The pin 24 slides the rotary shaft 22 by pushing it to the original position. Therefore, the cover 40 returns to the original position.

The hinge and electronic device described above have the following advantages. When the cover 40 rotates at an angle, the hinge lifts the cover 40 up smoothly. Therefore, the shape of the electronic device does not impair the appearance, and the cover 40 does not interfere with the lid 60. Furthermore, the above-described electronic device can be made small, and the cover 40 can be smoothly rotated to have a very beautiful shape.

Even if many features and advantages of the present invention are described as described above, the configurations and features of the present invention are merely examples, and the present invention is not limited to these examples. In particular, changes in shape, size, arrangement, and the like of components of the present invention are not sufficient in the detailed description, and the terms expressed in the claims should be interpreted according to a broad general meaning.
