Detailed Description

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is an assembled view of the electronic device of the present invention, fig. 2 is an exploded view of fig. 1, and fig. 3 is a partial perspective view of fig. 1. Please refer to fig. 1, fig. 2 and fig. 3.

The electronic device 100 includes a first body 110, a second body 120, and a hinge 130. The first body 110 is, for example, a display screen, and the first body 110 has a first pivot portion 112. The second body 120 is, for example, a bracket, and the second body 120 has a second pivot portion 122. In the embodiment, the first pivoting portions 112 are provided as a pair, and the second pivoting portion 122 is located between the pair of first pivoting portions 112.

The hinge 130 is connected between the first body 110 and the second body 120 such that the first body 110 can rotate relative to the second body 120 through the hinge 130.

Specifically, the hinge 130 includes a rotating shaft 131, an adjustment knob 132, a permanent magnet chuck 133, a magnetic conductor clutch 134, and a return spring 135. The shaft 131 passes through the second pivot portion 122, and two ends 131a and 131b of the shaft 131 are sleeved in the first pivot portion 112, so that the first body 110 can rotate relative to the second body 120 with the shaft 131 as a rotation axis. The electronic device 100 further includes a plurality of screws 140 and a pair of protective covers 150, wherein the screws 140 are used to lock the ends 131a and 131b of the shaft 131 to the first pivot portion 112, and the protective covers 150 are covered on the first pivot portion 112 to shield the ends 131a and 131b of the shaft 131.

The adjustment knob 132 is rotatably disposed on the second body 120.

The permanent magnetic chuck 133 is disposed in the second body 120, wherein the permanent magnetic chuck 133 includes a first permanent magnet 1331 (shown in fig. 4A), a second permanent magnet 1332 (shown in fig. 4A) and a yoke 1333 (shown in fig. 4A). The yoke 1333 is located between the first permanent magnet 1331 and the second permanent magnet 1332. The first permanent magnet 1331 and the second permanent magnet 1332 have an N pole and an S pole, respectively, wherein the N pole and the S pole of the second permanent magnet 1332 are fixed.

The first portion 132a (shown in fig. 4A) of the adjustment knob 132 penetrates the second body 120 and the first permanent magnet 1331 is disposed around the first portion 132a, and the adjustment knob 132 rotates to drive the first permanent magnet 1331 to rotate to change the state of the magnetic loop of the permanent magnet chuck 133. Specifically, when the adjustment knob 132 rotates, the positions of the N pole and the S pole of the first permanent magnet 1331 are changed, so that the magnetic fields generated by the N pole and the S pole of the second permanent magnet 1332 are also changed, resulting in different states of the magnetic loop. This will be described in detail later.

The magnetic conductor clutch 134 penetrates through the rotating shaft 131, is located between the first pivoting portion 112 and the second pivoting portion 122, and has different distances from the permanent magnetic chuck 133 under the influence of the state of the magnetic loop.

The return spring 135 is disposed between the second pivot portion 122 and the magnetic conductor clutch 134 for providing an elastic restoring force to the magnetic conductor clutch 134.

The hinge 130 further includes a shaft snap ring 136, a snap ring 137, and a friction plate 138.

The shaft snap ring 136 is sleeved on the rotating shaft 131 and is arranged between the permanent magnetic chuck 133 and the return spring 135. The shaft snap ring 136 is used to fix the rotation shaft 131 to the second body 120.

The spring retainer ring 137 is sleeved on the rotating shaft 131 and is arranged between the permanent magnetic chuck 133 and the return spring 135. More specifically, the spring retainer 137 is located between the shaft retainer ring 136 and the return spring 135. The spring retainer 137 is configured to abut against the return spring 135 to confine the return spring 135 between the magnetic conductor clutch 134 and the spring retainer 137. This is because the diameter of the rotating shaft 131 is smaller than the spring diameter of the return spring 135, so that the return spring 135 can be biased against an unexpected structure by the end (not shown) of the permanent magnetic chuck 133 against the return spring 135 without the spring retainer 137.

A friction plate 138 is disposed on the surface 133a of the permanent magnet chuck 133 facing the magnetic conductor clutch 134. The friction plate 138 is used to prevent the magnetic conductor clutch 134 and the permanent magnetic chuck 133 from rubbing against each other and being damaged due to the relative rotation between the first body 110 and the second body 120 when the magnetic conductor clutch 134 is attracted by the permanent magnetic chuck 133.

In addition, the second body 120 of the present embodiment further has three indication patterns 120a, 120B, and 120C (shown in fig. 5A, 5B, and 5C, respectively), but not limited thereto. When the adjusting knob 132 points at one of the three indicating

patterns

120a, 120b, 120c, the user can clearly know the locking state between the first body 110 and the second body 120 through the indicating

pattern

120a, 120b, or 120c pointed by the adjusting knob 132.

Fig. 4A to 4C are schematic diagrams of the permanent magnetic chuck in different magnetic loop states. Fig. 5A to 5C are the magnetic conductor clutch and the permanent magnetic chuck in the attraction state corresponding to fig. 4A to 4C. Fig. 6A to 6C are rotatable states of the first body relative to the second body corresponding to fig. 5A to 5C.

Please refer to fig. 4A, fig. 5A and fig. 6A simultaneously. When the adjusting knob 132 is rotated to point the adjusting knob 132 to the unlocking indication pattern 120a, the S pole of the first permanent magnet 1331 and the N pole of the second permanent magnet 1332 are located at the same side, and the N pole of the first permanent magnet 1331 and the S pole of the second permanent magnet 1332 are located at the other side. At this time, the permanent magnetic chuck 133 is in a closed magnetic loop state and does not generate a magnetic force to the magnetic conductor clutch 134. The magnetic conductor clutch 134 is disengaged from the permanent magnet chuck 133 by the elastic restoring force provided by a return spring 135 (shown in fig. 2). At this time, the first body 110 can be largely rotated with respect to the second body 120 by using the rotation shaft 131 (shown in fig. 2) as a rotation axis.

Please refer to fig. 4B, fig. 5B and fig. 6B simultaneously. When the adjusting knob 132 is rotated to make the adjusting knob 132 point to the half-locked indication pattern 120b, the first permanent magnet 1331 is driven by the adjusting knob 132 to make the magnetic pole (S pole or N pole) thereof relatively close to and located between the N pole and S pole of the second permanent magnet 1332, and at this time, the permanent magnet chuck 133 is in a half-closed magnetic loop state. The magnetic force provided by the permanent magnet chuck 133 attracts the magnetic conductor clutch 134 toward the permanent magnet chuck 133 and against the friction plate 138 (shown in fig. 2), but the permanent magnet chuck 133 does not completely grip the magnetic conductor clutch 134 tightly. Therefore, the first body 110 can be rotated by a fine adjustment of the rotation angle with respect to the second body 120 by using the rotation shaft 131 (shown in fig. 2) as the rotation axis, but the first body 110 cannot be adjusted by a large angle with respect to the second body 120 due to the attraction between the magnetic conductor clutch 134 and the permanent magnetic chuck 133. When the permanent magnet chucks 133 are in a semi-closed magnetic loop state, the magnetic attraction force provided by the permanent magnet chucks 133 to the magnetic conductor clutch 134 is greater than the elastic restoring force provided by the return spring 135 (shown in fig. 2).

Please refer to fig. 4C, fig. 5C and fig. 6C simultaneously. When the adjusting knob 132 is rotated to point the adjusting knob 132 to the locked indication pattern 120c, the S pole of the first permanent magnet 1331 and the S pole of the second permanent magnet 1332 are located at the same side, and the N pole of the first permanent magnet 1331 and the N pole of the second permanent magnet 1332 are located at the other side. At this time, the permanent magnetic chuck 133 is in an open magnetic loop state. The magnetic force provided by the permanent magnet chuck 133 causes the magnetic conductor clutch 134 to be drawn tightly against the friction plate 138 (shown in FIG. 2). At this time, since the magnetic force provided by the permanent magnetic chuck 133 is large, the first body 110 cannot rotate with respect to the second body 120 by an angle with the rotation shaft 131 (shown in fig. 2) as the rotation axis. As such, the first body 110 is maintained at a fixed angle with the second body 120.

Therefore, by simply moving and rotating the adjusting knob, the position of the magnetic pole of the first permanent magnet in the permanent magnet chuck can be changed, and the state of a magnetic loop formed by the interaction of the first permanent magnet and the second permanent magnet is further changed, so that the adsorption degree (namely the tightness degree of the hinge) between the magnetic conductor clutch and the permanent magnet chuck is changed.

In addition, the hinge can have a fully relaxed state and a fully locked state.

The difference between the torque provided by the hinge in the fully released state and the fully locked state is large, and is completely different from the difference between the forces in the locked state and the released state of the conventional hinge control structure.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
