In addition, when the movable arm is separated from the protruding part, the rotating member is no longer restricted so that the torsion spring can drive the rotating shaft to return.

The detailed description and technical content of this new model are described as follows in conjunction with the drawings:

Please refer to Fig. 1 to Fig. 8, the present invention provides a kind of uniaxial hinge 10, comprises two mounting parts 11, a rotating shaft 13, a rotating member 15 and a torsion spring 17, and these two mounting parts 11 provide an external structure respectively (in the figure (not shown) assembly, and the external structure can be two parts of a portable electronic device, such as the host and the screen, and the two installation parts 11 can be relatively opened or closed after being operated. The two mounting parts 11 are respectively formed with a shaft joint hole 111, and the two shaft joint holes 111 provide the rotating shaft 13 to pass through the two mounting parts 11, so that the rotating shaft 13 has a rotation in situ when the two mounting parts 11 are opened. One of the two shaft connection holes 111 allows the shaft 13 to axially displace relative to the two installation components 11 , so that the shaft 13 has an axial displacement stroke 132 .

Further, one of the two mounting parts 11 forms a protruding part 113, the rotating part 15 is arranged on the rotating shaft 13 and is located on the side where the two mounting parts 11 are provided with the protruding part 113, and the rotating part 15 has a The movable arm 151 protruding in the direction of the protruding part 113, the rotating member 15 rotates with the rotating shaft 13 and drives the movable arm 151 to displace relative to the protruding part 113, the protruding part 113 is located within the movable range of the movable arm 151, the movable The arm 151 can only pivot in one direction relative to the protrusion 113 when in contact with the protrusion 113 , as indicated by reference numeral 152 . In addition, the torsion spring 17 is sleeved on the rotating shaft 13 and its two ends are respectively fixed to the rotating member 15 and one of the two mounting parts 11. The torsion spring 17 is deformed with the rotation of the rotating member 15, thereby storing elastic force. Once the torsion spring 17 can release the elastic force, it drives the rotating member 15 to return. In one embodiment, the torsion spring 17 has a first fixed end 171 fixed on the rotating member 15 , and a second fixed end 172 fixed on one of the two mounting parts 11 . In another embodiment, the protruding portion 113 of the two mounting components 11 is provided with a slot 114 , and the slot 114 provides the second fixed end 172 of the torsion spring 17 to be disposed.

Referring again to Fig. 3 to Fig. 8, the implementation of the uniaxial hinge 10 will now be described. The uniaxial hinge 10 has an open state when the rotating shaft 13 performs the rotation stroke 131 during implementation, and when the rotating shaft 13 A restricted state after reverse rotation, and a closed state when the rotating shaft 13 travels the axial displacement stroke 132 . Assume that initially, the two mounting parts 11 are not relatively open, as shown in FIG. 3 . Once the two mounting parts 11 are opened relative to each other, the rotating shaft 13 is affected by the two mounting parts 11 to perform the rotation stroke 131, so that the single-axis hinge 10 enters the opened state. In the open state, the rotating member 15 drives the movable arm 151 , so that the movable arm 151 contacts the protruding portion 113 and pivots relative to the protruding portion 113 in one direction. Thereafter, the movable arm 151 will continue to rotate relative to the protruding portion 113 , and when the movable arm 151 is no longer in contact with the protruding portion 113 , the movable arm 151 will return to the state when it is no longer pivoted. Moreover, when in the open state, the torsion spring 17 is deformed by the rotating member 15 and stores elastic force.

When the two mounting parts 11 no longer receive external force, the torsion spring 17 releases part of the elastic force, so that the rotating shaft 13 rotates opposite to the rotation stroke 131 (as shown by the symbol 130), and the single-axis hinge 10 enters the restricted state. In the restricted state, since the movable arm 151 cannot pivot relative to the protruding portion 113 , the movable arm 151 abuts against the protruding portion 113 and restricts the rotating shaft 13 from continuing to rotate in reverse. Once the rotating shaft 13 is axially pushed to perform the axial displacement stroke 132, the single-axis hinge 10 enters the closed state. In the closed state, the rotating shaft 13 pushes the rotating member 15, so that the movable arm 151 is separated from the protruding portion 113. At this moment, the movable arm 151 and the rotating member 15 are no longer restricted, so that the torsion spring 17 can Release the elastic force and drive the rotating shaft 13 to return.

It can be seen from the foregoing that the rotation of the rotating shaft 13 is restricted through the arrangement of the movable arm 151 in the present invention, thereby producing a positioning effect on the two mounting components 11 . In addition, when the movable arm 151 disengages from the protruding portion 113 , the rotating member 15 is no longer restricted so that the torsion spring 17 can drive the rotating shaft 13 to return.

The first fixed end 171 of the torsion spring 17 is assembled between the hole 154 and the second pivot hole 155 , so that the movable arm 151 can pivot relative to the rotating member 15 . In addition, in order to restrict the movable arm 151 from pivoting in one direction, in one embodiment, the rotating member 15 has a pivot slot 157 and a limiting block 158, the pivot slot 157 provides the movable arm 151 to set, To allow the movable arm 151 to pivot therein, the restricting block 158 is disposed on the movable arm 151 and is located at one side of the movable arm 151 , and the restricting block 158 restricts the movable arm 151 to only pivot in one direction. In addition, in order to assist the movable arm 151 to pivot relative to the protruding portion 113, in one embodiment, the movable arm 151 has a plurality of guide slopes 159, and these guide slopes 159 are set in succession and are located away from the movable arm 151. The limit block 158 side. Also, the present invention is to assist the movable arm 151 against the protruding portion 113, the movable arm 151 has a limiting plane 160, the limiting plane 160 is located on one side of the movable arm 151 and can contact the protruding portion 113, the limiting The plane 160 connects one of the guiding slopes 159 and makes the movable arm 151 limited by the protruding portion 113 .

In addition, please refer to FIGS. 2 to 8 again. In one embodiment, the rotating shaft 13 has an operating portion 133 that protrudes from the two mounting parts 11. The operating portion 133 provides user operation. After the operating portion 133 is operated, it will make The rotating shaft 13 travels the axial displacement stroke 132 . Also, the present invention is to make the rotating shaft 13 push the rotating member 15. In one embodiment, the rotating shaft 13 is formed by at least two mutually socketed shaft parts 134, and one of the two shaft parts 134 is provided with the operating shaft at one end. part 133, and the other end is provided with a push surface 135 to the rotating part 15, the pushing surface 135 contacts the rotating part 15 after the operating part 133 is operated, and then makes the movable arm 151 move away from the protruding part 113 direction displacement.

Bearing in mind, the present invention is to make the rotating shaft 13 return. In one embodiment, the rotating shaft 13 forms a protrusion 136. The single-axis hinge 10 has a sleeve 18 and a compression spring 19. The sleeve 18 is sleeved on the rotating shaft. 13 and located on one side of the rotating member 15, the compression spring 19 is sleeved on the rotating shaft 13 and faces the sleeve 18, the two ends of the compression spring 19 respectively contact the sleeve 18 and the protrusion 136, the compression spring 19 against the protrusion 136, and accept the pressure from the sleeve 18, once released, the compression spring 19 releases the elastic force and pushes the sleeve 18, so that the rotating member 15 can be installed toward the two The direction of component 11 is reset.
