[0039] The folding device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] Reference Figure 1-Figure 5 As shown, the folding device 100 according to the embodiment of the present invention may include: a connecting seat 10 and an adjusting component 20 .

[0041] Specifically, a gear portion 11 is provided on the connecting seat 10, and the adjustment assembly 20 includes a cover assembly 21 and a moving member 22. The cover assembly 21 is rotatably connected to the connecting seat 10 via a rotating shaft 30, so that the cover assembly 21 can be rotated for folding adjustment, making the folding process smooth.

[0042] The moving member 22 is movably disposed in the cover assembly 21. The moving member 22 has a length direction (eg Figure 4 A limit gear 221 is provided at one end of the gear portion 11 (in the front-to-back direction shown in FIG), and the gear portion 11 is disposed in the cover assembly 21. The gear portion 11 can mesh with the limit gear 221, and the limit gear 221 is disposed in the length direction of the gear portion 11 (for example, Figure 4 Thus, when the gear portion 11 is meshed with the limit gear 221, the rotation position of the adjustment assembly 20 can be limited, thereby limiting the different gears of the folding device 100. The meshing of the limit gear 221 with the gear portion 11 at different positions can achieve multi-gear adjustment of the folding device 100, meet the different gear adjustment requirements, and facilitate accurate control of the folding position.

For example, the cover assembly 21 can be rotated upward or downward to adjust the folding angle of the cover assembly 21; when the limit gear 221 is meshed with the gear portion 11, the position of the cover assembly 21 can be locked to fix the angle.

[0044] Therefore, when the cover body assembly 21 rotates, the interference between the limit gear 221 and the gear part 11 can be avoided by moving the movable part 22, so that adjustment is convenient, and the rotation angle of the cover body assembly 21 can be adjusted at any time without folding to the uppermost gear and then adjusting the gear from the beginning, that is, it can be unlocked and readjusted at any gear, which is conducive to improving the user experience.

[0045] In some embodiments, Figure 4 and Figure 5 As shown, one end of the moving member 22 in the length direction is provided with a first connection hole 224 and extends into the limiting gear 221.

The fastener passes through the first opening 225 and is connected to the first connection hole 224, which can realize the connection between the moving member 22 and the limiting gear 221, ensure reliable connection, and facilitate disassembly. For example, the first connection hole 224 is an M6 threaded hole, and the fastener is a screw.

For example, the second connection hole 111 is an M6 threaded hole.

[0047] In some embodiments, Figure 3 and Figure 4 As shown, the second opening 13 is along the length direction of the connecting seat 10 (for example Figure 4 The second connecting holes 111 are arranged in a one-to-one correspondence with the second openings 13, and multiple fasteners can be respectively passed through the second openings 13 to be connected with the second connecting holes 111, so that the connecting seat 10 and the gear part 11 can be connected at multiple different positions to ensure reliable connection.

[0048] In the embodiment of the present invention, the number of the second openings 13 can be flexibly set according to actual conditions. For example, the second openings 13 can be Figure 3 Two are shown, but three, four, five, six or more may also be provided, all of which are within the protection scope of the present invention.

The rotating section 231 is rotatably connected to the cover body assembly 21, so that the button 23 can be connected to the cover body assembly 21. One end of the connecting section 232 is connected to the rotating section 231, and the other end of the connecting section 232 is passed through the moving part 22, so that the button 23 can be connected to the moving section.
