For example, the biaxial hinge is initially implemented with only single-axis rotation, and only switches to biaxial simultaneous movement after a certain angle.

However, the current biaxial hinges still have the following technical problems when in use:

Although the dual-axis hinge has two axes, it still maintains a switching rotation mode when rotating, that is, it is still composed of multiple sections of single-axis rotation states to form a 360-degree rotation. There is still no technical content to change the rotation form of the hinge, and it is unable to meet special needs.

Therefore, a biaxial hinge with a uniaxial implementation mode is proposed to solve the above-mentioned problems.

Example

Please refer to Figures 1-9, the utility model provides a technical solution:

A double-axis hinge with a single-axis implementation mode includes a double-axis hinge body, the double-axis hinge body includes a base 21, a first axis 22 and a second axis 23 are inserted and arranged inside the base 21, and the first axis 22 and the second axis 23 are parallel; a transmission member 24 is arranged inside the base 21, a switching member 25 is arranged on the outside of the first axis 22 at the left end of the base 21, a connecting member 26 is arranged on the outside of the first axis 22 at the left end of the switching member 25, the switching member 25 is a tubular structure, and the switching member 25 is restricted to move between the connecting member 26 and the base 21, a first torque generating group 27 is arranged on the right end of the first axis 22 and the second axis 23, and a first torque generating group 27 is arranged on the left end of the first axis 22 The second torque generating group 28, the switching member 25 is used not only for switching the state of the double-axis hinge, but also for driving the first axis 22 to rotate. The switching member 25 is not fixed on the first axis 22, and the switching member 25 can move appropriately along the first axis 22. The switching member 25 is limited to move between the connecting member 26 and the base 21. The connecting member 26 is provided with an external component (not shown in the figure). Although the connecting member 26 and the switching member 25 are installed on the first axis 22, there is no direct transmission relationship between the connecting member 26 and the first axis 22. That is to say, when the connecting member 26 rotates, the first axis 22 assembled with the connecting member 26 may not rotate at the same time;

A third concave-convex portion 211 is formed on the left side wall of the base 21 at the left end of the first shaft 22. A guiding inclined surface 212 is formed on the upper end of the third concave-convex portion 211. A groove bottom surface 213 is formed on one end of the guiding inclined surface 212. A stop surface 214 is formed on one end of the groove bottom surface 213.

A non-circular section 221 is formed at the left end of the first shaft 22 , a first threaded section 222 is formed at the right end of the outer wall of the first shaft 22 , and a second threaded section 232 is formed at the outer wall of the second shaft 23 ;

A left first concave-convex portion 251 is formed on the left side wall of the switching member 25, a right first concave-convex portion 252 is formed on the right side wall of the switching member 25, and a non-circular hole 253 is formed inside the switching member 25;

The connecting member 26 includes a first plate member 262 and a second plate member 263 . The side wall of the connecting member 26 is provided with a second concave-convex portion 261 . The left side wall of the connecting member 26 is provided with a driving portion 264 . The right side wall of the second plate member 263 is provided with a mounting portion 265 . The driving portion 264 cooperates with the mounting portion 265 .

The outer wall of the non-circular segment 221 is slidably connected to the inner wall of the non-circular hole 253 .

The right ends of the first shaft 22 and the second shaft 23 are plugged into the left side wall of the first torque generating group 27 , and the second torque generating group 28 is plugged into the left end of the first shaft 22 .

The transmission member 24 is meshed with the first thread segment 222 and the second thread segment 232 respectively.

The side wall of the second plate 263 is provided with symmetrical mounting holes.

The switching member 25 has a left first concave-convex portion 251 and a right first concave-convex portion 252 at both ends facing the connecting member 26 and the base 21 respectively. The connecting member 26 has a second concave-convex portion 261 facing the switching member 25 and cooperating with the left first concave-convex portion 251. The base 21 has a third concave-convex portion 211 facing the switching member 25 and cooperating with the right first concave-convex portion 252. Please refer to FIG. 3 for combination. The switching member 25 has only the following two states according to the rotation angle of the biaxial hinge: the switching member The left first concave-convex portion 251 of the switching member 25 is engaged with the right second concave-convex portion 261; the right first concave-convex portion 252 of the switching member 25 is engaged with the third concave-convex portion 211. Based on the above two states, the double-axis hinge has a single-axis implementation mode that only allows the connecting member 26 to rotate relative to the first axis 22 when the right first concave-convex portion 252 is engaged with the third concave-convex portion 211, and a double-axis implementation mode that allows the first axis 22 and the second axis 23 to move simultaneously when the left first concave-convex portion 251 is engaged with the right second concave-convex portion 261. Furthermore, if the second concave-convex portion 261 and the third concave-convex portion 251 are observed from one end of the first shaft 22 and the second shaft 23, it can be found that the second concave-convex portion 261 and the third concave-convex portion 211 do not overlap, so that the second concave-convex portion 261 and the third concave-convex portion 211 are engaged with the left first concave-convex portion 251 and the right first concave-convex portion 252 at different time points (i.e., at different opening angles of the biaxial hinge);

The biaxial hinge can be opened 360 degrees. For specific explanation, this article will start with Figure 4 as the initial state (i.e., the 0-degree state). When the biaxial hinge is in the 0-degree state, the right first concave-convex portion 252 of the switching member 25 is engaged with the third concave-convex portion 211, and the biaxial hinge is in the single-axis implementation mode. At this stage, the connecting member 26 is driven by the external structure to rotate, and the rotation of the connecting member 26 at this stage will not drive the first shaft 22. Specifically, the first shaft 22 is restricted by the switching member 25 at this stage and cannot rotate, and the restriction of the switching member 25 is formed by the engagement of the right first concave-convex portion 252 with the third concave-convex portion 211. As mentioned above, when the connecting member 26 continues to rotate to 120 degrees (i.e., FIG. 5), the second concavoconvex portion 261 enters a position that can engage with the left first concavoconvex portion 251 of the switching member 25 as the connecting member 26 rotates. At this time, the user's force applied to the double-axis hinge will cause one of the first and second axes 22 and 23 that is not provided with the switching member 25 to rotate, and the first and second axes 22 and 23 will move simultaneously at this point. When the first and second axes 22 and 23 move simultaneously, the switching member 25 is affected and displaced on the first axis 22, and changes its state, turning to the engagement of the left first concavoconvex portion 251 and the second concavoconvex portion 261, as shown in FIG. 6 and FIG. 7. Further, at this point in time, the switching member 25 can link the connecting member 26 due to the engagement of the left first concavoconvex portion 251 and the second concavoconvex portion 261, so that the connecting member 26 rotates accordingly. After the biaxial hinge is opened 120 degrees, the biaxial implementation mode is maintained until a 360-degree rotation is completed (see Figures 8 and 9). The closing of the biaxial hinge is the reverse implementation as mentioned above, which will not be described in detail here.

The second shaft 23 has a non-circular segment 221 assembled with the switching member 25, and the switching member 25 has a non-circular hole 253 corresponding to the non-circular segment 221. The non-circular hole 253 is a part of the space formed by the tubular structure of the switching member 25. Furthermore, the first shaft 22 can cut the plane to realize the non-circular segment 221, and the shape of the non-circular segment 221 can correspond to the shape of the non-circular hole 253.

The biaxial hinge has two first torque generating groups 27 respectively arranged on the first axis 22 and the second axis 23, and a second torque generating group 28 arranged on the first axis 22. The composition of the first torque generating group 27 and the second torque generating group 28 can be implemented by selecting corresponding structures according to the implementation requirements, and the present invention is not limited thereto. Furthermore, when the biaxial hinge is in the single-axis implementation mode, the left first concave-convex portion 251 of the switching member 25 abuts against the surface of the connecting member 26, so that the second torque generating group 28 presses the connecting member 26, generating the torque required for the connecting member 26 to rotate in this mode.

The second concavo-convex part 261 and the third concavo-convex part 211 respectively have one of the following: at least two protrusions and at least two grooves. The left first concavo-convex part 251 and the right first concavo-convex part 252 respectively have at least two protrusions, and the second concavo-convex part 261 and the third concavo-convex part 211 respectively have at least two grooves. Each of the at least two grooves has a guiding inclined surface 212, one of which is connected to the groove bottom surface 213 of the guiding inclined surface 212, and the other is connected to the stop surface 214 of the groove bottom surface 213. The shape of the at least two protrusions can correspond to the at least two grooves, and the positions of the two stop surfaces 214 of the at least two grooves need to be set according to the opening rotation direction of the first shaft 22. More specifically, when the first shaft 22 rotates in the opening rotation direction, the contact order of the two protrusions and the two grooves is the guiding inclined surface 212, the groove bottom surface 213, and finally the stop surface 214. When the two protrusions touch the stop surface 214 of the two grooves, the aforementioned engagement is completed. When the first shaft 22 rotates in the closing direction, the two protrusions contact the stop surface 214 , the groove bottom surface 213 , and the guiding inclined surface 212 in sequence.

The transmission member 24 is a helical gear, and the first shaft 22 and the second shaft 23 have a first thread segment 222 and a second thread segment 232 that cooperate with the transmission member 24 .

The connecting member 26 includes a first plate 262 and a second plate 263. One of the first plate 262 and the second plate 263 facing the switching member 25 is formed with a second concave-convex portion 261. The second concave-convex portion 261 formed on the first plate 262 and the second plate 263 is used to drive the driving portion 264 adjacent to the first plate 262 and the second plate 263. The first plate 262 and the second plate 263 have a mounting portion 265 assembled with the driving portion 264. The driving portion 264 can be a latch, and the mounting portion 265 can be a through hole provided with the latch.
