Description

  The present invention relates to a hinge, and more particularly, to a hinge having simplified components disposed between a cover and a base of an electronic device.

  An electric device such as a notebook computer or a mobile phone includes a cover, a base, and a hinge. The conventional hinge connects the cover to the base along the horizontal axis and the longitudinal axis so that the cover can be rotated with respect to the base. In order to prevent the electronic device from being damaged when the cover is rotated with respect to the base, in the conventional hinge mechanism, spacers having structures corresponding to each other are provided in order to provide a positioning function and a limiting function. We use a lot.

However, each such corresponding spacer needs to rotate with respect to each other to provide positioning and limiting functions, and when the corresponding spacers rotate relative to each other, the spacers rub against each other and It will be worn out. Therefore, such a conventional spacer is easily damaged.
In order to prevent or mitigate these disadvantages, the present invention provides a hinge with reduced wear.

Rotate with respect to. Still referring to FIG. 10, if it is desired to rotate the cover 50 relative to the base 60, the cover 50 causes the fastening bracket 46 to rotate relative to the central bracket 10.

  3, 4, 8, and 9 show a state where the cover 50 is opened and closed with respect to the base 60. The first arm 12 rotates with respect to the inclined shaft 21.

  Since the fixed positioning spacer 22 is mounted on the inclined shaft 21, the first arm 12 rotates with respect to the fixed positioning spacer 22. When the at least one positioning detent 126 of the first arm 12 engages with the at least one positioning protrusion 222, the cover 50 is positioned with respect to the base 60.

The limiting projection 124 of the first arm 12 abuts on the limiting projection 214 of the inclined shaft 21 and limits the rotation angle of the cover 50.
When the first arm 12 rotates with respect to the inclined shaft 21, the limiting head 213 of the inclined shaft 21 rubs the inner annular recess 122 and the inclined surface 123 of the first arm 12. Since the strength of the material increases when pressed, the inner annular recess 122 and the inclined surface 123 of the first arm 12 increase the strength of the first arm 12 and wear against the limiting head 213 of the inclined shaft 21. cut back. On the same principle, the outer annular recess 125 reduces wear on the outer surface of the first arm 12.

  3, 4, 8, and 10 to 12, the cover 50 is shown rotated with respect to the base 60. The tightening bracket 46 rotates the central shaft 41 with respect to the central bracket 10.

  Since the rotational positioning spacer 43 is firmly mounted on the central shaft 41, the rotational positioning spacer 43 can rotate with respect to the main arm 11 of the central bracket 10. When the at least one positioning protrusion 431 of the rotational positioning spacer 43 engages with the at least one positioning detent 113 of the main arm 11, the cover 50 is positioned with respect to the base 60.

  Since the rotation limiting spacer 45 is mounted on the central shaft 41, the rotation limiting spacer 45 rotates with respect to the fixed limiting spacer 44 and the main arm 11. Limiting projections 451 and 452 of the rotation limiting spacer 45 abut against the limiting projections 114, 441 and 441 ′ of the main arm 11 and the fixed limiting spacer 44 to limit the rotation angle of the cover 50.

  When the rotation positioning spacer 43 rotates with respect to the main arm 11, the inner surface of the main arm 11 is rubbed, but the annular recess 115 of the main arm 11 reduces the wear of the main arm 11.

  When the flat side portion 413 of the limiting head 411 of the central shaft 41 is aligned with the positioning head 212 of the inclined shaft 21, the positioning protrusion 216 is disengaged from the engagement of the annular slot 414 in the limiting head 411 of the central shaft 41. The limiting head 411 can rotate with respect to the positioning head 212 of the inclined shaft 21. Therefore, the central shaft 41 can be rotated with respect to the inclined shaft 21.

  When the limiting side 412 of the limiting head 411 of the central shaft 41 is aligned with the positioning head 212 of the inclined shaft 21, the positioning protrusion 216 engages with the annular slot 414 of the limiting head 411 of the central shaft 41, and the inclined shaft 21 is No rotation with respect to 41. Accordingly, even when the cover 50 is rotated and opened with respect to the base 60, the cover 50 is not inadvertently closed, so that unnecessary damage can be prevented.
