Hinge mechanism

The present invention relates to a mechanical component, and more particularly to a hinge mechanism.

A hinge mechanism is a mechanical bearing that is disposed between two elements and allows one of the elements to be rotatable relative to the other of the elements. Referring to FIGS. 1 and 2, a plurality of hinges 2 are attached to the back of the tablet 1 , and the hinge mechanism 2 is connected to a support plate 3 . The support plate 3 can be pivoted relative to the tablet 1 by the hinge mechanism 2 . To support the tablet 1 and tilt it to the table.

Referring to Figures 3 and 4, the hinge mechanism 2 includes a shaft 21 and a sleeve 22 disposed on the shaft 21 and in an interference fit therewith. The shaft 21 is formed with a projection 211 and the sleeve 22 is formed with a stopper 221 . The shaft 21 is pivotable relative to the sleeve 22 over an angular range, and a frictional force is generated between the shaft 21 and the sleeve 22 so that the shaft 21 can be within the angular range. Position at any angle. In addition, by blocking the protrusion 211 of the shaft 21 by the stopping portion 221 of the sleeve 22, the pivoting angle of the shaft 21 can be prevented from exceeding the angle range.

However, when the shaft 21 blocked by the stopping portion 221 continues to be applied with a force to pivot it, the sleeve 22 may be broken and disengaged to cause the shaft 21 and the sleeve 22 to be The frictional force is lowered, which in turn causes the positioning function of the shaft 21 within the angular range to fail. For this reason, most of the thickness of the sleeve 22 is increased to strengthen the structural strength of the hinge mechanism 2, but this method makes the space occupied by the hinge mechanism 2 too large, which is not in line with the current demand for light and thin electronic products. There is still room for improvement.

Therefore, it is an object of the present invention to provide a hinge mechanism capable of avoiding a decrease in torque due to excessive force.

Therefore, in some embodiments, the hinge mechanism of the present invention is adapted to rotate a first plate body and a second plate body. The hinge mechanism includes a shaft and a sleeve disposed on the shaft. The shaft includes a first connecting arm portion for connecting the first plate body, a rod body connecting the first connecting arm portion, and a first body disposed on the rod body adjacent to the first connecting arm portion Bump. The rod body has a front section connecting the first connecting arm portion, a rear section opposite to the front section, and a middle section between the front section and the rear section, the A bump is disposed on the front section of the rod. The sleeve includes a tube body disposed on the shaft of the shaft, and a second connecting arm portion connecting one side of the tube body and adapted to connect the second plate body. The tube body has a stopping portion adjacent to the first connecting arm portion, an interference portion extending from the stopping portion toward the first connecting arm portion, and two disposed on the blocking portion and adjacent to the tube body The first blocking portion of the opening. A first gap is formed between the stop segment and the front portion of the shaft, and the interference segment is in interference fit with the middle portion of the shaft. The shaft of the shaft is rotatable about its own axis to rotate the first plate relative to the second plate, and the first protrusion of the shaft is driven at the first blocking portion of the tube Move between.

In some embodiments, the tube body of the sleeve further has an auxiliary section extending from the interference section away from the first connecting arm portion, and the auxiliary section forms a rear section with the rear section of the rod body. There is a second gap.

In some embodiments, the shaft further includes a second protrusion disposed on the rear section of the rod body, the tube body of the sleeve further having two disposed on the auxiliary section and adjacent to the tube body a second blocking portion of the opening, the second projection being driven to rotate between the second blocking portions of the tubular body when the shaft of the shaft is rotated.

The present invention has at least the following effects: since the stop segment of the tubular body and the front segment of the shaft do not contact each other, the tubular body is opened when the first projection abuts against one of the first blocking portions At the same time, the change in the torsion between the interference segment of the tubular body and the middle portion of the shaft is not caused. Compared with the thickness of the conventional thickened sleeve to strengthen the structural strength of the hinge mechanism, the structure is more simplified and conforms to the current demand for light and thin electronic products.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 5 and 6, a first embodiment of the hinge mechanism of the present invention is adapted to support a support plate for supporting a tablet computer (the tablet computer and the support plate are not shown in the drawings). The computer turns. The hinge mechanism includes a shaft 4 and a sleeve 5 disposed on the shaft 4. The shaft 4 includes a first connecting arm portion 41 connected to the supporting plate, a rod body 42 connecting the first connecting arm portion 41, and a rod body 42 disposed adjacent to the first connecting arm portion 41. The first bump 43. The rod body 42 has a front section 421 connecting the first connecting arm portion 41, a rear section 422 opposite to the front section 421, and a portion between the front section 421 and the rear section 422. Medium section 423. In other words, the other end of the shaft 4 from the first connecting arm portion 41 to the shaft 4 is the front portion 421, the middle portion 423, and the rear portion 422, respectively, and the first The bump 43 is provided in the front section 421 of the rod 42.

Continuing to refer to Figures 5 and 6, the sleeve 5 includes a tubular body 51 disposed on the shaft 42 of the shaft 4, and a side connecting the side of the tubular body 51 and connecting the back of the tablet. The second connecting arm portion 52. The tube body 51 has a blocking portion 511 adjacent to the first connecting arm portion 41, an interference portion 512 extending from the stopping portion 511 away from the first connecting arm portion 41, and an interference segment 512. The auxiliary section 513 extends away from the first connecting arm portion 41. That is, the tubular body 51 from the end adjacent to the first connecting arm portion 41 to the other end of the tubular body 51 is the stopping segment 511, the interference segment 512, and the auxiliary segment 513, respectively. The tubular body 51 also has two first blocking portions 514 disposed in the stop segment 511 and formed in the opening of the stop segment 511.

Referring to FIGS. 7-10, the interference section 512 of the tubular body 51 is in interference fit with the middle section 423 of the shaft 4, but the stop section 511 and the auxiliary section 513 and the rod of the shaft 4 A first gap 515 and a second gap 516 are formed between the bodies 42 (see FIGS. 8 and 10), that is, the blocking section 511 and the auxiliary section 513 are not in contact with the shaft of the shaft 4. 42. The shaft 42 of the shaft 4 is rotatable about its own axis, thereby enabling the support plate to rotate relative to the tablet. In addition, when the shaft 4 rotates, the first protrusion 43 of the shaft 4 is moved between the first blocking portions 514 of the tube body 51 (see FIGS. 7, 9). In other words, the rotation of the shaft 4 can only be rotated within a certain range of angles because the first protrusion 43 is blocked by the first blocking portions 514, so that the support plate can only be in the specific angle range. The inside rotates relative to the tablet. Furthermore, by the torsion generated between the middle section 423 of the rod 42 and the interference section 512 of the tube 51, the support plate can be positioned by the influence of friction force, so that the support plate will The tablet stands on the desktop.

It should be particularly noted that if the first protrusion 43 of the shaft 4 is blocked against one of the first blocking portions 514 of the tube 51, if the support plate is improperly operated by the user Sustained under pressure, the first projection 43 of the shaft 4 will open the stop section 511 of the tubular body 51. However, since the stop section 511 does not contact the front section 421 of the rod body 42, the interference section 512 of the tube body 51 and the rod body 42 are not ignited even if the tube body 51 is opened. The torque between the middle sections 423 changes, and the positioning function of the support plate can be maintained. Compared with the previous practice of thickening the thickness of the sleeve to strengthen the structural strength of the hinge mechanism, the structure is more simplified and conforms to the current demand for light and thin electronic products.

Referring to FIG. 11, which is a second embodiment of the hinge mechanism of the present invention, the second embodiment is substantially the same as the first embodiment, and the difference is that the tube body 51 of the second embodiment further has two The auxiliary section 513 is formed in a second blocking portion 517 of the opening of the auxiliary section 513 (only one of which is shown in FIG. 11). In addition, the shaft 4 of the second embodiment further includes a second protrusion 44 disposed on the rear section 422 of the rod body 42 and fixed to the rod body 42 by screwing. The second protrusion 44 is driven between the rods 42 of the shaft 4 to move between the second blocking portions 517 of the tube 51, and functions similarly to the first portion of the shaft 4 The relationship between the bumps 43 and the first blocking portions 514 of the tubular body 51. The function of providing these components is to share the force that the interference segment 512 is abutted by the shaft 4. If the first bump 43 supports the stop segment 511 of the tubular body 51, the auxiliary segment 513 can serve as the auxiliary segment 513. A second mechanism that blocks the rotation of the shaft 4. Moreover, the auxiliary section 513 does not contact the rear section 422 of the rod body 42, so that the interference section 512 of the tube body 51 and the rod body 42 are not ignited even if the tube body 51 is opened. The torque between sections 423 varies.

In summary, the hinge mechanism of the present invention does not cause the interference of the tube 51 even if the tube 51 is disengaged because the stop portion 511 does not contact the front portion 421 of the rod 42. The torque between the segment 512 and the middle section 423 of the rod 42 varies to maintain the positioning function of the support plate. Compared with the previous practice of thickening the thickness of the sleeve to strengthen the structural strength of the hinge mechanism, the structure is more simplified and conforms to the current demand for light and thin electronic products, so the purpose of the present invention can be achieved. In addition, the second bump 44 and the auxiliary segment function to share the force that the interference segment 512 is abutted by the shaft 4, in case the first bump 43 supports the stop segment 511 of the tubular body 51. The auxiliary section 513 can serve as a second mechanism for blocking the rotation of the shaft 4.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
