In detail, the aforementioned connecting mechanism 30 includes a connecting piece 31 and a fixing piece 32. One end E1 of the connecting piece 31 is fixed to the first back surface 102 of the first display module 10, and the other end E2 has a spherical structure 311. The connecting piece 31 can be used as a universal joint. The second display module 20 has a accommodating portion 21, which includes a flexible or elastic material and has a hollow structure, and is formed on the second back surface 202 of the second display module 20. The aforementioned spherical structure 311 is snapped and accommodated in the accommodating portion 21, and through the fixing member 32, the spherical structure 311 can be fixed to the accommodating portion 21, as shown in FIG. 3. In this way, the second display module 20 can be firmly connected to the first display module 10.

Specifically, as shown in FIG. 2, the fixing member 32 can be used as a fixing ring, which has a substantially circular slot 321, and the spherical structure 311 of the connecting member 31 can be inserted into the slot 321. The fixing member 32 also has a first threaded structure T1, and the outer or outer edge of the receiving portion 21 has a second threaded structure T2, which are matched with each other. Referring to Figures 4A and 4B, the spherical structure 311 of the connecting member 31 is arranged in the accommodating portion 21, and the first threaded structure T1 of the fixing member 32 and the second threaded structure T2 of the accommodating portion 21 are locked and combined to make The second display module 20 is firmly locked on the connecting mechanism 30.

In more detail, referring to the cross-sectional schematic diagrams of the connecting member 31 and the second display module 20 in FIGS. 4A and 4B, the spherical structure 311 of the connecting member 31 passes through the fixing member 32 and is partially disposed in the receiving portion 21 for use The fixing member 32 can be rotated in the rotation direction R1 as shown in FIG. 3 to rotate relative to the receiving portion 21 to move/rotate the fixing member 32 from a loosening position X0 (first position; Fig. 4A) to a Fixing position X1 (the second position; Fig. 4B), at this time, a first inclined surface S1 of the inner edge of the fixing member 32 abuts against and presses the outer or outer edge of the receiving portion 21 in the direction of the central axis O of the fixing member 32 A second inclined surface S2 deforms and shrinks the inner diameter of the opening of the receiving portion 21 so that the inner edge of the opening abuts and tightly buckles the spherical structure 311. In this way, through the combination of the first and second thread structures T1 and T2 and the first inclined surface S1 abuts against the second inclined surface S2, both the second display module 20 and the first display module 10 will be firmly fixed, so that the display The device is locked.

When the user wants to adjust the angle or position of the second display module 20 relative to the first display module 10, the fixing member 32 can be rotated in a rotation direction R2 (refer to FIG. 3) opposite to the rotation direction R1, so that The fixing member 32 is separated from the fixing position X1. At this time, the connecting member 31 is no longer tightly fixed with the receiving portion 21, and the second inclined surface S2 is no longer pressed by the first inclined surface S1 in the direction of the central axis O at the fixing position X1, and As a result, the accommodating portion 21 no longer fastens the spherical structure 311 tightly, and the user can rotate the second display module 20 at this time. In other words, when the spherical structure 311 is located in the accommodating portion 21, and the fixing member 32 is not in the fixed position X1, the fixing member 32 is tied between the loosening position X0 or the loosening position X0 to the fixing position X1, and the display device 1 appears at this time In the half-locked state, the second display module 20 can rotate or move relative to the first display module 10. In addition, referring to FIG. 3, the outer edge of the fixing member 32 has a tapered tip 323, which can increase the convenience of holding and provide the user with more convenient rotation of the fixing member 32.

It is worth noting that the fixing member 32 also includes a clamping portion 322, as shown in FIG. 4A, the clamping portion 322 clamps the spherical structure 311 of the connecting member 31, wherein the clamping portion 322 to the fixing member 32 The shortest distance of the central axis O is smaller than the shortest distance from the first threaded structure T1 of the fixing member 32 to the central axis O, which can ensure that the fixing member 32 firmly clamps the spherical structure 311 at the fixed position X1.

Figure 5 shows a schematic cross-sectional view of the connecting mechanism 30. In this embodiment, the connecting member 31 and the fixing member 32 of the connecting mechanism 30, and the receiving portion 21 of the second display module 20 all have a hollow structure, so that a circuit module W (or wires, signal wires) can be connected to the first display module 10 from the second display module 20 through the accommodating portion 21, the fixing member 32 and the connecting member 31. In this way, the circuit module W is embedded Being not exposed in the second display module 20, the connecting mechanism 30, and the first display module 10 not only improves the appearance of the display device 1, but also avoids the situation that the wiring is arranged around the device and the user needs to arrange the wiring. Improve the convenience of use.

Figures 6 and 7 show schematic diagrams of the second display module 20 being rotatable relative to the first display module 10. Figure 6 shows that the second display module 20 can be rotated up and down (rotating around the Y axis). The figure shows that the second display module 20 can rotate left and right (rotate around the Z axis). Of course, the second display module 20 rotates on the aforementioned single axis, by means of the spherical structure 311 of the connecting member 31, the second The display module 20 can be rotated in a full-circumferential direction. When the fixing member 32 leaves the fixed position X1 on the receiving portion 21 (for example, moves to the release position X0), the second display module 20 can rotate relative to the first display module 10 by applying a force, wherein It is worth mentioning that at this time, the user can change the ease of rotation of the second display module 20 relative to the first display module 10 by adjusting the tightness of the fixing member 32 to the receiving portion 21. For example, when the fixing member 32 is on the receiving portion 21 and is close to the end of the fixed position X1, the second display module 20 is tighter than when it is close to the end of the release position X0. The group 10 rotates, that is, a greater force must be applied to be able to rotate the second display module 20. Conversely, when the fixing member 32 is closer to the release position X0, the user is more likely to rotate the second display module 20. By rotating the fixing member 32 by the user, the degree of tightness of the second display module 20 relative to the first display module 10 can be adjusted.
