Please refer to Fig. 1 to Fig. 6, damping due to rotation hinge of the present invention it includes: a shell 1 is both ends open or open at one end
Staving, be equipped with inside the shell 1 directly to multiple limit grooves 10；One rotation cam 2, is set to inside the shell 1, one end
Equipped with one first cam end 21；One torque spring 3 is set in the shell 1；One sealed base 4 is fixed in the shell 1；One
Axle center 5 is sealed, is fixed in the shell 1；One damping cam 6, be equipped with outside the damping cam 6 directly to multiple limit raised lines
60, it can cooperate with the limit groove 10 of the shell 1, be merely able to axial linear motion, one to limit the damping cam 6
End is equipped with one second cam end 61 and abuts first cam end 21 of the rotation cam 2, and the other end is equipped with and the torque spring 3
One first bearing surface 62 abutted is pushed when being rotated by the rotation cam 2 with the interference engagement of first cam end 21
Form axial linear motion；
And 61 side of the second cam end is equipped with circular hole 610 in one first, and enters the sealing for 610 groups of circular hole in first in this
Axle center 5 forms one first oil storage room 7；First bearing surface, 62 side is equipped with one second circular hole 620, this in second circular hole group enter this
Sealed base 4 forms one second oil storage room 8, and the resistance of a limitation flow is equipped between first oil storage room 7 and second oil storage room 8
Buddhist nun hole 9 after so that the damping cam 6 is generated round-trip axial linear movement by the torque spring 3 of arranging in pairs or groups, that is, is formed complete
Oil pressure damping mechanism.
From the above, which is connected on first bearing surface 62, and the other end is connected to the sealed base
On 4, which is pushed by the compressed spring force of torque spring 3, the damping cam 6 is enable to generate straight line fortune
Dynamic thrust generates the torque other than damping force whereby.
Referring to Fig. 2, wherein the shell 1 interior can be equipped with internal screw thread 11 and one end is equipped with a torque and adjusts pedestal 12, it should
12 periphery of torque adjustment pedestal has external screw thread 120 and one end is connected to the sealed base 4, adjusts pedestal using the torque is adjusted
12 lock the mode of stroke, control the relative position of the sealed base 4, adjust the compression travel and bullet of the torque spring 3 whereby
Spring force, and control the torque of damping due to rotation hinge.
Fig. 3 to Fig. 6 is please referred to, one embodiment of the invention is disclosed, wherein is equipped with a valve inside first circular hole 610
Piece fixing seat 611, the valve block fixing seat 611 are equipped with an overflow step 612, set between the valve block fixing seat 611 and the damping cam 6
There is a valve block 613, the valve block 613 is pushed by damping oil flowing, and the damping hole 9 and the overflow step 612 is cooperated to make this
Valve block 613 can control the gap of the damping hole 9 of the damping cam 6 when axial straight line back and forth movement, whereby control damping
Oil is at different operation direction toward the flowing velocity of another oil storage room.
From the above, a damping spring 63 is equipped in the damping cam 6, which is equipped with one second and supports
Junction 631a is connected in the valve block fixing seat 611, and the other end is equipped with a third bearing surface 632a and is connected to the sealing axle center 5
On, which is pushed by the compressed spring force of damping spring 63, the valve block fixing seat 611 is made to follow this
It damps the linear motion of cam 6 and moves, limit the scope of activities of the valve block 613 whereby；When have external force be greater than power of the invention
When square, damping cam 6 will form the axial linear movement for being pushed to 3 direction of torque spring, because the position of sealed base 4 is solid
It is fixed, therefore damp cam 6 and will push damping oil and flow to first oil storage room 7 by the damping hole 9 from second oil storage room 8, and hinder
Buddhist nun's oil also pushes valve block 613 far from damping hole 9 simultaneously, and damping oil is allowed to flow to the resistance of first oil storage room 7 from second oil storage room 8
Power is greatly decreased and generates small damping force；Conversely, damping cam 6 can be by torque when external force disappears or external force is less than the present invention
Spring 3 is pushed away toward the movement of rotation 2 direction of cam, and because the position in sealing axle center 5 is the axial movement meeting fixed, therefore damp cam 6
It pushes damping oil to be back to second oil storage room 8 by damping hole 9 from first oil storage room 7, while pushing valve block 611 to keep off together
Firmly damping hole 9, the resistance for causing damping oil to flow to second oil storage room 8 from first oil storage room 7 is very big and generates big damping
Power forms the effect slowly automatically turned on.
Fig. 7 to Figure 10 is please referred to, another embodiment of the present invention is disclosed, a valve block is equipped with inside second circular hole 620
Fixing seat 611, the valve block fixing seat 611 are equipped with an overflow step 612, are equipped between the valve block fixing seat 611 and the damping cam 6
One valve block 613 pushes the valve block 613 by damping oil flowing, and the damping hole 9 and the overflow step 612 is cooperated to make the valve
Piece 613 can control the gap of the damping hole 9 of the damping cam 6 when axial straight line back and forth movement, control damping oil whereby
At different operation direction toward the flowing velocity of another oil storage room.
From the above, a damping spring 63 is equipped in the damping cam 6, which is equipped with one second and supports
Junction 631b is connected in the valve block fixing seat 611, and the other end is equipped with a third bearing surface 632b and is connected to the sealed base 4
On, which is pushed by the compressed spring force of damping spring 63, the damping cam 6 is enable to generate straight line fortune
Dynamic thrust generates the torque other than damping force whereby；When there is external force to be greater than torque of the invention, the present invention can turn external force
Become the axial linear movement for pushing damping cam 6 toward 3 direction of torque spring, at this point, because the position of sealed base 4 is fixed, therefore
The axial linear movement of damping cam 6 can push damping oil to flow to first storage by damping hole 9 by second oil storage room 8 simultaneously
Grease chamber 7, and damping oil also can push simultaneously valve block 613 to block damping hole 9, cause damping oil should from second oil storage room 8 flow direction
The resistance of first oil storage room 7 is very big and generates damping force, reaches the function of slowly closing；And torque spring 3 is also because of decrement
Increase and increase spring force, damping cam 6 i.e. because spring force increase, cause push rotation cam 2 turning moment also with
Increase, the slave object closing velocity for installing equipment of the invention is also made also to increase and slow down with torque of the invention；Conversely, working as external force
It disappears or when less than torque of the invention, which can be pushed by the spring of torque spring 3 toward rotation cam 2, and because close
The axial movement that the position in envelope axle center 3 is fixed, therefore damps cam 6 can push damping oil from first oil storage room 7 by hindering simultaneously
Buddhist nun hole 9 is back to second oil storage room 8, and pushes valve block 613 far from damping hole 9 together, makes damping oil from first oil storage room 7
The resistance for flowing to second oil storage room 8 is greatly decreased and generates small damping force, makes damping force of present invention when opening from object remote
It is low compared with when closing from object.
The above is merely a preferred embodiment of the present invention, cannot be to limit the scope of the invention, all abilities
Field technique personnel the variation and improvement that can obviously make, all should be regarded as falling into substantive content of the invention.
