Different torques are generated depending on the corresponding portions of the convex member 50 and the concave member 40. [Selection diagram] Fig. 2

Description

  The present invention particularly relates to a hinge that is mounted between a base and a cover of a portable device and rotates the cover relative to the base.

  As shown in Patent Document 1, a hinge used in a conventional portable electronic device is one in which a cover is pulled up by a convex member 50 and a concave member 40, and the convex member 50 is provided at an opposite position. The concave member 40 has a pair of convex portions, and the concave and convex surface of the concave member 40 is formed on the surface, so that the convex portion of the convex member 50 rotates while contacting the concave and convex surface of the concave member 40. In some cases, a different torque is generated. This is in the field of hinges in which a structure that is raised and lowered on the surface of the concave member 40 is designed, and different torques are generated when a pair of convex portions of the convex member 50 rotate while contacting the concave member 40. For example, Patent Document 2 has a structure like this technique.

  In addition, another conventional technique related to a hinge is often made up of two sets of concave and convex positioning members (having two concave members 40 and two convex members 50). In this case, for example, Patent Document 3 and As shown in Patent Document 4, there is no problem even if the torque change is increased by the two sets of concave / convex positioning members, and two or more portable electronic devices are provided depending on the fitting angle of the two sets of concave / convex positioning members. The positioning angle can be maintained. For example, one set of uneven positioning members is effective when the cover is mounted on the base, and the other set of uneven positioning members is effective when the cover is lifted by 30 ° from the base.

A recess 45, a pair of second positioning recesses 46 that are provided in the second side surface 43 and formed at opposite positions, and a pair of second positioning recesses 46 that are provided in the second side surface 43 and provided at opposite positions, respectively. A pair of first positioning protrusions 47 is provided.

  Further, the first positioning convex portion 47 is located between the first positioning concave portion 45 and the second positioning concave portion 46, and inclined surfaces are formed on both side edges, respectively, and the center on the first side surface 42 is further formed. A first axis 451, a second axis 461, and a third axis 471 passing through the hole 41 at different angles are defined, and the first axis 451 is the center of the pair of first positioning recesses 45. The second axis 461 passes through the center of the one-to-second positioning recess 46, and the third axis 471 corresponds to the pair of first positioning projections 47. It passes through the center of Each first positioning recess 45 preferably occupies a 20 ° arcuate portion on the circumference of the recess member 40.

As described above, the noise canceling member 57 has a notch 571 and the noise canceling member 57 is manufactured by a press molding technique, and thus has high accuracy. Further, since the conventional concave member 40 and the convex member 50 are generally manufactured by MIM means, the accuracy of the center hole 51 may be low. Therefore, in the process of rotating the hinge, the concave member 40 and the convex member 50 with low accuracy are good and there is noise with the pivot 20. If there is a noise removing member 57 with high accuracy, it is firmly combined with the rod body 21 and engaged with the engaging protrusion 56 by the notch 571 to prevent noise generation.

  As shown in FIG. 8, the portable device according to the present invention has a cover 90, a base 91, and at least one of the above-described hinges. In this embodiment, the portable device is provided between the cover 90 and the base 91. In addition, hinges are installed on both sides of the cover 90 and the base 91, respectively. Further, the hinges 11 are fixed to the base 91 with the fixed wings 11 of the fixed seat 10 and the rotating seat 30 is fixed to the cover 90. The rotary seat 30 rotates the pivot 20 and the convex member 50 with respect to the concave member 40.

In the present invention, the height of the positioning convex portion and the depth of the positioning concave portion are provided with symbols, and the height from the second side surface 43 of the concave portion 40 to the first positioning convex portion 47 is defined as H. _1, and the height of the height from the first side 52 of the projecting member 50 until the second positioning projection 54 which projects and H _2, to the third positioning projection 55 which projects from the first side surface 52 of the projecting member 50 was a _{H 3,} the depth of the first positioning recess 45 and D _1, the depth of the second positioning recess 46 with a _{D 2, they, H 2> H 3, H} 2> H 1, H 1 + H ₃ > H ₂ . Further, when the second positioning convex portion 54 is engaged so as to correspond to the first positioning concave portion 45, the height of the portion where the second positioning convex portion 54 is fitted into the first positioning concave portion 45 is L, D ₁ ≧ L and D ₂ ≧ L− (H ₂ −H ₃ ).

As shown in FIGS. 9 to 12, when the cover 90 is folded on the base 91, the second positioning convex portion 54 of the convex member 50 is engaged with the first positioning concave portion 45 of the concave member 40 (see FIG. 11). At this time, the third positioning convex portion 55 of the convex member 50 accommodates the second positioning concave portion 46 of the concave member 40 (as shown in FIG. 12), and D ₂ ≧ L− (H ₂ −H ₃ ) described above. Therefore, the numerical value at which the height of the second positioning convex portion 54 inserted into the first positioning concave portion 45 reduces the difference between the second positioning convex portion 54 and the third positioning convex portion 55 is the second positioning convex portion 54. Since the depth of the second positioning recess 46 is smaller than the depth of the recess 46, it is possible to fit the entire third positioning projection 55, and the second positioning projection 54 is engaged with the first positioning recess 45. You can also. When the cover 90 starts to be pulled up, a first peak torque is generated and the second positioning convex portion 54 can be separated from the first positioning concave portion 45.

As shown in FIGS. 9 and 13 to 15, if the cover 90 is continuously lifted, the second positioning convex portion 54 of the convex member 50 slides on the second side surface 43 of the concave member 40. The generated general torque is generated, and at this time, the relationship of H ₂ > H ₃ is established, that is, the height of the second positioning convex portion 54 is higher than that of the third positioning convex portion 55, so that the third positioning convex portion Even if 55 is separated from the second side surface 43 of the recess member 40, it is not engaged with the second positioning recess 46.

As shown in FIGS. 9 and 16 to 18, when the cover 90 continues to be pulled up and reaches a position of 45 ° from the base 91, the third positioning convex portion 55 of the convex member 50 is just the first positioning convex portion of the concave member 40. Since the convex member 50 is pressed and separated from the concave member 40 due to the contact with the portion 47, a second peak torque is generated. At this time, the relationship of H ₁ + H ₃ > H ₂ is established. Since the total height of the first positioning convex portion 47 and the third positioning convex portion 55 is higher than that of the first positioning concave portion 45, the second positioning convex portion 54 is separated from the second side surface 43 of the concave portion 40. However, no general torque is generated. In this embodiment, the second peak torque may be smaller than the first peak torque, but this is not a condition limited by the present invention. The torque can also be changed, and the first peak torque may be smaller than the second peak torque.

  As shown in FIGS. 9 and 19 to 21, when the cover 90 is continuously lifted and reaches a position exceeding 45 ° from the base 91, the third positioning convex portion 55 is separated from the first positioning convex portion 47 and is second. Since peak torque is not generated and the second positioning convex portion 54 is restored to the second side surface 43 of the concave member 40, a general torque may be provided.

  Since the present invention has the above-described configuration, a set of concave members and convex members generate different torques due to changes in corresponding portions between the positioning convex portions and the positioning concave portions, and the positioning convex portions rotate to be different. Even if torque is generated, the operation is smoothly performed so as not to affect each of them, and the installation location of the concave and convex positioning members may be replaced, and even in that case, the function of the hinge is not affected. So that the operation is performed normally.
