Embodiments of the invention

[0021] In order to more clearly understand the technical features, objects and effects of the present invention, the embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0022] As shown in FIG. 1 and 2, a support device according to an embodiment of the present invention is configured to carry a flexible screen (not shown), including but not limited to a bendable support frame 10, a positioning elastic piece 20, and two positioning positions. Agency 30.

[0023] The support frame 10 is elongated and can be bent from a flat shape into a curved shape so as to be worn on the wrist of the user. The curved shape means that both ends of the support frame 10 and the intermediate portion of the support frame 10 are not located. On the same level. Each positioning elastic piece 20 is disposed on one side of the supporting frame 10 in the bending direction of the supporting frame 10, that is, the side of the supporting frame 10 on which the positioning elastic piece 20 is disposed is opposite to the flexible screen. In the present embodiment, the flexible screen supporting device includes two positioning elastic pieces 20, and each positioning elastic piece 20 is disposed on a lower surface of the supporting frame 10 in a bending direction. A flexible screen is disposed on the upper surface of the support frame 10. Each positioning mechanism 30 is disposed on one end portion 100 of the support frame 10 and abuts against the positioning elastic piece 20 for state locking of the support frame 10. That is, the positioning structure 30 can lock the support frame 10 in a certain curved or horizontal state.

[0024] wherein the positioning elastic piece 20 extends along the length direction of the supporting frame 10, and the two end portions 200 of the positioning elastic piece 20 are respectively extended toward the two end portions 100 of the supporting frame 10. Each end portion 100 of the support frame 10 is provided with at least one positioning site 120; the positioning mechanism 30 cooperates with the end portion 200 of the positioning elastic piece 20, and the end portion 200 of the positioning elastic piece 20 is bent or restored in the supporting frame 10 along the supporting frame. The end 100 of 10 is moved to the positioning site to lock the current state of the support frame 10.
