As shown in Fig. 7, Fig. 8, Fig. 9, the middle and lower part of cam shaft 24 of the present invention is equipped with cam 2411, lower cam set 242,
Lower cam set 242 is equipped with lower cam set ramp 2421 and lower cam set plate rail 2422, and cam 2411 will cover ramp in lower cam
2421 and lower cam set plate rail 2422 on move；
State 1：When hinge is closed（Not loaded on door）When, cam 2411 is in the bottom of lower cam set ramp 2421.
State 2：By hinge it is mounted on a door after, under shutdown state, cam 2411 be in lower cam set ramp 2421 in
Between position on the lower side, spring 261 is in by compress energy storage state, is relative to 241 rotation angle α of cam shaft group during state 1
（0 °~30 °）.
State 3：When door is opened into 90 ° ± 20 °, cam 2411 is rotated up and is arrived at along lower cam set ramp 2421
Lower cam covers plate rail 2422, makes 242 continuation slide downward certain distance of lower cam set and makes 261 compress energy storage of spring, relative to
241 rotation angle β of cam shaft group is 90 ° ± 20 ° during state 2, is relative to 242 slide downward distance a of cam sleeve during state 1
4mm~7mm (i.e. spring is 4mm~7mm by reduction length a).
State 4：When door is opened into 180 °, cam 2411 continues to rotate along lower cam set plate rail 2422, and cam 242 is not
It slides still further below, spring 261 keeps compressive state, is 180 o relative to 241 rotation angle γ of cam shaft group during state 2, complete
180 ° of standard-sized sheet door state corotating.
In conclusion when cam shaft group 241 rotates to 90 °~180 °（I.e. open angle is 90 °~180 °）, cam
2411 contact with cam sleeve plate rail 2422, therefore can hover any position in this range inside door.
State 5：When door is closed to 90 °, cam 2411 rotates along lower cam set plate rail 2422 and arrives at lower cam set
2421 top of ramp, when door is not acted on by other external force in addition to hinge, energy will be discharged by remain the spring 261 of compression
Amount generates a upward dynamic lower cam set 242 of pushing and moves upwards, and it is downward that cam 2411 will cover ramp 2421 along lower cam
It slides, cam shaft group 241 is made to cover 242 with lower cam and generates relative motion.Due to cam sleeve 242 relative to determine hinge 25 can only
It does and is axially moved up and down, cam shaft group 241 will be made along the direction for closing door（Or the negative direction to open the door）Rotation, dynamic circuit connector hinge
12 drive doors are automatically closed, and spring 261 also keeps certain compressive state, continues downward cam sleeve 242 and applies upward power, makes
Door is closed tight.It therefore can be with automatic door-closing in the range of realizing open angle less than 70 °~90 °.
In addition, door is divided into left and right opening door mode, Fig. 6, Fig. 7 are left and right Liang Zhong cam shafts mechanisms, direction of rotation phase
Instead, be respectively used to it is left inside open and have external-open, open and opened on four kinds of door-opening modes with left outside in the right side, as Fig. 6 uses are opened in the right side（It is or left
External-open）On hinge, Fig. 7 uses are opened left inside（Or right external-open）On hinge.
