FIG. 9B is an enlarged schematic view of a partial combination of the support member and the flexible protective member in FIG. 9A from other viewing angles. Please refer to FIGS. 9A and 9B , different from the foldable electronic device 100 shown in FIG. 2B and the support 140 shown in FIG. 3A , in the foldable electronic device 100A of this embodiment, the first back of the first body 110 a is The side 111 is provided with at least one ball 115, and the support 140a has at least one guide groove 143 facing the first back side 111 of the first body 110a. The balls 115 are slidably arranged in the guide grooves 143 to improve the support The sliding smoothness and stability of the member 140a.

For example, the number of the balls 115 may be multiple, wherein the multiple balls 115 are roughly divided into two rows and symmetrically distributed on the first body 110a. Correspondingly, the number of the guide grooves 143 can be two, and they are symmetrically distributed on the support member 140a.

To sum up, in the foldable electronic device of the present invention, the flexible protective member covers the first back side of the first body and the second back side of the second body, so that it can prevent foreign objects or external forces from affecting the first body and the second body. Damage is caused to the surface of the second body. On the other hand, the flexible guard covers the hinge and the gap between the first body and the second body, so it can prevent the intrusion of foreign objects and maintain the integrity of the appearance. Further, the flexible guard can slide moderately according to the rotation direction and rotation angle of the first body and the second body, and the two positioning fasteners corresponding to the hinges press against the flexible guard. Based on the above design, the flexible guard will not hinder the rotation of the first body and the second body, so the foldable electronic device has excellent smoothness of operation. In addition, the flexible guard will not be pushed up by the first body and the second body when rotating, so that the appearance flatness can be maintained.

Although the present invention has been disclosed above by the embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The protection scope of the present invention shall be determined by the scope of the appended patent application.
