In addition, please refer to FIG. 5A and FIG. 7A at the same time. In this embodiment, the electronic device 100 further includes a plurality of second elastic members 160 . Each second elastic member 160 has an opposite first connecting end 161 and a second connecting end 162, and the second elastic member 160 is an arc-shaped linear spring. The first connection end 161 and the second connection end 162 are connected to the first housing 110 and the second housing 120 respectively, and the second connection end 162 is adapted to follow the second housing 120 along the first direction D1 (ie, along the Z axis direction), while the first connecting end 161 is fixed to the first housing 110 without moving.

As shown in FIG. 5A, in this embodiment, when the second housing 120 is still in the folded state M1 (FIG. 5A), the second connecting end 162 has its elastic force downward on the first side S1. At this time, the second elastic force is downward. The member 160 will resist the upward pulling force of the second housing 120 (that is, the force toward the second side S2) to prevent the second housing 120 from being accidentally triggered due to external force in the folded state M1, causing the second housing 120 to 120 cannot move to the second side S2 at will.

During the transition from the folded state M1 (FIG. 5A) to the unfolded state M2 (FIG. 7A), when the second connecting end 162 follows the second housing 120 in the first direction D1 (ie, the Z-axis direction and toward the second side When moving in the direction of arrow S2), the distance between the second connecting end 162 and the first connecting end 161 is shortened, thereby compressing the elastic force of the second elastic member 160. Once the second connecting end 162 moves beyond the first connecting end 161, the compressed second elastic member 160 instantly releases its elastic force to urge the second connecting end 162 to move to the second side S2, whereby the second connecting end 162 moves to the second side S2. The connecting end 162 drives the second housing 120 to move to the second side S2 to assist the second housing 120 to continue moving to the second side S2.

On the contrary, as shown in FIG. 7A , in this embodiment, when the second housing 120 in the unfolded state M2 is stationary, the second connecting end 162 has its elastic force upward on the second side S2. At this time, the second elastic member 160 will resist The downward pushing force of the second housing 120 (i.e., the force toward the first side S1) prevents the second housing 120 from being accidentally triggered due to external force in the unfolded state M2, and prevents the second housing 120 from being arbitrarily pushed toward the first side due to gravity. Side S1 moves. In other words, the upward elastic force of the second elastic member 160 assists in supporting the overall weight of the second housing 120 .

During the transition from the unfolded state M2 (FIG. 7A) to the folded state M1 (FIG. 5A), when the second connecting end 162 follows the second housing 120 in the first direction D1 (ie, the Z-axis direction and toward the first side When moving in the direction of arrow S1), the distance between the second connecting end 162 and the first connecting end 161 is shortened, thereby compressing the elastic force of the second elastic member 160. Once the second connecting end 162 moves beyond the first connecting end 161, the compressed second elastic member 160 instantly releases its elastic force to urge the second connecting end 162 to move to the first side S1, whereby the second connecting end 162 moves to the first side S1. The end 162 drives the second housing 120 to move to the first side S1 to assist the second housing 120 to continue moving to the first side S1.

To sum up, in the electronic device of the present invention, by adjusting the movement of the second housing relative to the first housing to switch between the folded state and the unfolded state, a flexible screen can be selected for the electronic device according to needs. display range. Moreover, when the second housing moves to the unfolded state relative to the first housing and the support housing is exposed, the connecting rod assembly can be configured to be affected by the movement of the second housing relative to the first housing. Driven, the support housing moves relative to the first housing along the second direction to be coplanar with the second housing, so as to contact and support the flexible screen together with the second housing to prevent the flexible screen from being in the display range Wrinkles or dents are partially produced in the middle, thereby smoothing the transition process between the folded state and the unfolded state of the electronic device and improving the user's experience.

Although the present invention has been disclosed above through embodiments, they are not intended to limit the present invention. Anyone with ordinary knowledge in the technical field may make some modifications 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 appended patent application scope.
