  • the cam assembly 160 does not generally urge the first or second frame assemblies 108 or 110 to move relative to each other.
  • any additional movement of the first frame assembly 108 away from the second frame assembly 110 when the hinge assembly 102 is in the intermediate position will move the cam assembly 160 away from the neutral, tipping point and generally automatically open the hinge assembly 102. More particularly, the first and second cam members 164 and 166 move past the rounded ends 174b and 176b of the body's cam portions 174 and 176 to second angled surfaces 174c and 176c of the cam portions 174 and 176 such that the body 162 no longer uniformly opposes the compression forces in the spring members 178 and 180.
  • any movement of the first frame assembly 108 toward the second frame assembly 110 when the hinge assembly 102 is in the intermediate position will move the cam assembly 160 away from the neutral, tipping point and generally automatically close the hinge assembly 102.
  • the first and second cam members 164 and 166 move away from the rounded ends 174b and 176b of the body's cam portions 174 and 176 and back toward the first angled surfaces 174a and 176a of the cam portions 174 and 176 such that the body 162 no longer uniformly opposes the compression forces in the spring members 178 and 180.
  • This allows the compressed spring members 178 and 180 to expand and push the cam members 164 and 166 generally along the first angled surfaces 174a and 176a. And in turn, this operates to automatically rotate the first frame assembly 108 back toward the second frame assembly 110 (without the user exerting any further force) and move the hinge assembly 102 back to its closed position (FIG. 10).
  • the stopping spring 182 engages a drive link 130 of the second drive assembly 126 and stops further relative rotation of the frame assemblies 108 and 110.
  • the stopping spring 182 can be configured to stop relative rotation of the frame assemblies 108 and 110 at a predetermined rotational angle 192 (e.g., open angle, etc.) (FIG. 11).
  • the stopping spring 182 is configured to stop relative rotation of the first and second frame assemblies 108 and 110 at a rotational angle 192 of about 160 degrees. It should be appreciated that the stopping spring 182 could be configured to stop relative rotation of the first and second frame assemblies 108 and 110 at rotational angles other than 160 degrees within the scope of the present disclosure.
  • the illustrated hinge assembly 102 is further hingedly moveable to the extended position (FIG. 14).
  • the stopping spring 182 is resiliently deformed (e.g., the head 186 of the stopping spring 182 is resiliently bent, moved, etc. relative to the base 184) by the drive link 130 of the second drive assembly 126 (allowing the further relative rotational movement of the frame assemblies 108 and 110).
  • This further relative rotational movement of the frame assemblies 108 and 110 can continue until the first and second moving shafts 138 and 146 engage end portions of their respective arcuate grooves 156 and 158. In the illustrated embodiment, for example, this relative rotational movement may continue until the first and second frame assemblies 108 and 110 reach a rotational angle of about 180 degrees.
  • the user can, for example, rotate the first frame assembly 108 toward the second frame assembly 110. This operation is substantially similar to the operation for opening the hinge assembly 102 previously described, and will therefore not be further described.
  • a hinge assembly generally includes two hinge frames coupled to a main body and a folder. Each hinge frame includes circular arc slits at both side ends.
  • the hinge assembly also generally includes two fixed shafts whose ends are both rotatably coupled to the hinge frames, two moving shafts whose ends are both movably coupled in the slits of the hinge frames, and a center shaft as a rotational shaft of the fixed shafts and the moving shafts.
  • the hinge assembly further generally includes a first drive link including a plurality of segments, one end of each of the segments being rotatably coupled to one of the fixed shafts, the other end of each of the segments being rotatably coupled to one of the moving shafts, and a middle point being rotatably coupled to the center shaft; and a second drive link including a plurality of segments which is generally symmetric to the segments of the first drive link, wherein one end of each of the segments is rotatably coupled to another one of the fixed shafts, the other end of each of the segments being rotatably coupled to another one of the moving shafts, and a middle point being rotatably coupled to the center shaft.
  • the hinge assembly also includes a cam body coupled to the center shaft.
  • the cam body includes a cam profile with upper and lower points of inflection around the center shaft. Hinge cams contact the cam profile of the cam body.
  • the hinge assembly also includes cam springs (e.g., bias springs, etc.). One end of each of the cam springs is fixed to the hinge frames and the other end is fixed to the hinge cams. Stop springs are included for stopping the hinge frames when the hinge frames have been opened to a predetermined open condition.
  • Each drive link includes three via holes.
  • the center shaft is inserted into the via holes at the middle points of the drive links.
  • Each of the segments of the first drive link and each of the segments of the second drive link are disposed alternately along the center shaft.
  • the moving shaft and the fixed shaft are inserted into the first and second drive links, respectively.
  • the fixed shaft may be positioned more inward than the moving shaft.
  • the moving shafts are inserted into the circular arc slits of the hinge frames.
  • the hinge assembly can be moved to an intermediate position (e.g., as described above in connection with FIG. 7, etc.) in which the hinge cams are positioned at corresponding points of inflection. If the hinge cams are positioned below the points of inflection, then the hinge frames will tend to be closed by an elastic force of the cam springs. If the hinge cams are positioned above the points of inflection, then the hinge frames will tend to be opened by an elastic force of the cam springs.
  • the stop springs stop the rotation of the hinge frames at a predetermined open condition (e.g., at 160 degrees opened condition, etc.).
  • the stop springs are mounted to the hinge frames. Two stop springs may be included in the example hinge assembly. Each stop spring contacts one of the drive links at the predetermined opened condition. When the hinge frames are opened at 160 degrees, the stop springs and the drive links contact each other. Then, the opening operation may stop.
  • the stop springs will be deformed for further opening of the hinge frames. If each of the moving shafts has been moved to the end of the slit, then the moving shafts cannot move any more. Thus, the opening operation may stop (e.g., at 180 degrees opened condition, etc.). If the user removes the applied force, then the hinge frames can come back to 160 degrees opened condition by the elastic force of the stop spring.

Abstract

L'invention concerne un ensemble d'articulation comprenant généralement un premier ensemble châssis configuré pour être accouplé au premier corps du dispositif de communication portable, et un deuxième ensemble châssis configuré pour être accouplé au deuxième corps du dispositif de communication portable. L'ensemble d'articulation donné à titre d'exemple comprend également généralement un premier ensemble d'entraînement, et un deuxième ensemble d'entraînement. Un arbre central accouple le premier ensemble d'entraînement au deuxième ensemble d'entraînement de sorte que le premier ensemble d'entraînement est en mesure de pivoter autour de l'arbre central par rapport au deuxième ensemble d'entraînement. De plus, le premier et le deuxième ensembles d'entraînement supportent le mouvement articulé du premier ensemble châssis par rapport au deuxième ensemble châssis entre au moins une position fermée et une position ouverte.
