[0024] As Figure 1-2As shown in the figure, the flipping mechanism 10 on the keyboard is arranged between two adjacent and independent housings 20 on the keyboard. Each housing 20 is provided with one or more circuit boards and button assemblies; the flipping mechanism 10 includes a hinged first rotating member 11 and a second rotating member 12. The first rotating member 11 and the second rotating member 12 are both provided with a limiting structure that can limit the relative rotation angle between the two. The first rotating member 11 and the second rotating member 12 both include an integrally formed positioning portion 1 and a rotating portion 2. The two matching positioning portions 1 are arranged coaxially along the axis and are both sleeved on a rotating shaft 13. Each positioning portion 1 extends to one radial side of a rotating portion 2 and can be fixed to the inner wall of a housing 20 through a locking member.

[0025] In the present utility model, by arranging the hinged first rotating member 11 and the second rotating member 12 between two independent housings 20 of the keyboard and respectively providing a limiting structure thereon, the relative flipping of the two housings 20 within a certain angle range can be realized, so as to drive the button assemblies on the two housings 20 to flip and fold synchronously relative to each other, thereby achieving the purpose of shortening the length of the keyboard to facilitate storage and carrying.

[0026] As Figure 1 shown, in an embodiment of the present utility model, a second rotating member 2 / first rotating member 11 is provided on one or both axial sides of each first rotating member 11 / second rotating member 12. The two adjacent first rotating members 11 and second rotating members 12 are both coaxially sleeved on a rotating shaft 13; in another embodiment of the present utility model, one or more positioning portions 1 are provided on one side of each rotating portion 2, and several positioning portions are arranged along the axis of the rotating portion; in still another embodiment of the present utility model, more than one clamping portion 3 is further provided on one side of the first rotating member 11 or the second rotating member 12. Each clamping portion 3 extends to the inside of a housing 20 and can clamp a circuit board.

[0027] As Figure 2 shown, in an embodiment of the present utility model, the positioning portion 1 of the first rotating member 11 or the second rotating member 12 is integrally formed with a housing 20.

[0028] In application, according to the length, thickness at the joint of the two housings 20 and the specific structure of the housing 20, the matching number of the first rotating member 11 and the second rotating member 12 in the flipping mechanism 10 and the number and structure of the positioning portions 1 and the clamping portions 3 thereon can be reasonably set to ensure that the circuit board inside the housing 20 always maintains a stable state during the flipping process of the housing 20.

[0029] As Figure 1-2 shown, in the above embodiment, the limiting structure includes cut grooves 4 provided at the opposite end portions of two adjacent rotating portions 2. Each cut groove 4 extends along the axis of a rotating portion 2, and each rotating portion 2 is embedded in the cut groove 4 of another adjacent rotating portion 2.

[0030] During the rotation process, the rotating parts 2 of the first rotating member 11 and the second rotating member 12 rotate relative to each other. The protrusions formed by one cut groove 4 on the rotating part 2 are blocked by another cut groove 4, so as to achieve the purpose of restricting the relative rotation angle between the two. The structure is simple and convenient for production and processing. In application, a buckle and a positioning structure can also be arranged on the rotating shaft 13 and the two rotating members to further restrict the smooth relative rotation between the two. This structure has many applications in the hinge assembly and belongs to the common knowledge of those in the pump field, so the structure will not be described in detail here.

[0031] As Figure 3-4 shown, in an application embodiment of the above embodiment, a foldable keyboard is disclosed. The keyboard is provided with two or more independent housings 20. Each housing 20 is provided with one or more circuit boards and button assemblies. One or more of the flipping mechanisms 10 in any of the above embodiments are provided between two adjacent housings 20.

[0032] To ensure that the keyboard maintains its normal use function, as Figure 1-4 shown, a through groove 6 for avoiding the FPC 5 and extending axially is further provided on the rotating part 2 of the first rotating member 11 or the second rotating member 12. An FPC 5 can pass through the through groove 6 and connect the circuit boards in two adjacent housings 20.

[0033] The FPC is a flexible circuit board, which has good flexibility itself. The normal relative flipping of the two housings 20 will not damage it, and it can connect the circuits in the two housings 20 to ensure that the keyboard can be used normally.

[0034] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
