The working principle of the wire take-up module is as follows: the base plate 4 is fixed in the first body 1, and is stationary relative to the first body 1, and whether the first body 1 and the second body 2 are in a closed state (as shown in fig. 5 and 6) or an open state (as shown in fig. 3 and 4), the elastic element 7 applies an acting force to the moving frame 8 away from the second body 2, the moving frame 8 moves relative to the base plate 4 in a direction away from the second body 2 under the acting force of the elastic element 7, and since the protection element 3 is connected to the moving frame 8, the protection element 3 is disposed on the flexible circuit board 5, and therefore, the moving frame 8 drives the flexible circuit board 5 to tighten in the direction away from the second body 2 through the protection element 3. This receipts line module makes flexible line way board 5 be in tensile tightening state all the time to when electronic equipment closed, flexible line way board 5 can not appear the fold at the rotation junction, reduces to expose, when electronic equipment overturns and opens, flexible line way board 5 is owing to stretch tightening, consequently, has avoided piling up the friction at the rotation junction.

In the present embodiment, the movable frame 8 and the bottom plate 4 are slidably connected, and thus the movable connection between the movable frame 8 and the bottom plate 4 is simple in structure. Of course, the movable frame 8 and the bottom plate 4 can be connected in a rolling way through rollers.

As optimizing, in this embodiment, receive line module still includes slide rail 6, and slide rail 6 is fixed in bottom plate 4 or removes frame 8, removes between frame 8 and the bottom plate 4 through slide rail 6 sliding connection. As shown in fig. 2, the slide rail 6 is fixed to the bottom plate 4, the slide rail 6 is stationary relative to the bottom plate 4, the guiding direction of the slide rail 6 is parallel to the winding direction of the flexible circuit board 5, the moving frame 8 is in sliding fit with the slide rail 6, and the moving frame 8 moves on the slide rail 6. Or the sliding rail 6 is fixed on the moving frame 8, the sliding rail 6 and the moving frame 8 are relatively fixed, the sliding rail 6 is in sliding fit with the bottom plate 4, and the moving frame 8 and the sliding rail 6 slide relative to the bottom plate 4 as a whole. As long as relative sliding between the moving frame 8 and the base plate 4 can be achieved.

Further, both sides of the movable frame 8 are slidably connected with the bottom plate 4 through the slide rails 6. So set up, make and slide more steadily between removal frame 8 and the bottom plate 4. Of course, the moving frame 8 can also be slidably connected with the bottom plate 4 through one or more sliding rails 6, and when one sliding rail 6 is provided, the sliding rail 6 is disposed at the centrosymmetric position of the moving frame 8 and the bottom plate 4, so as to ensure the moving stability of the moving frame 8.

As shown in fig. 2 to 6, in the present embodiment, the elastic member 7 includes at least two torsion springs, two ends of each torsion spring are respectively connected to the bottom plate 4 and the moving frame 8, and two ends of each torsion spring are arranged in a splayed shape. The torsion spring is characterized in that: the larger the angle of the two ends of the torsion spring which are opened outwards is, the larger the torsion force generated by the torsion spring is, and conversely, the smaller the torsion force is, namely, the torsion spring is a tensile torsion spring. Specifically, the bottom plate 4 and the movable frame 8 are both provided with positioning columns, wherein the positioning columns on the bottom plate 4 are arranged on one side away from the second body 2, the positioning columns on the movable frame 8 are arranged on one side close to the second body 2, and as shown in fig. 5 and 6, two ends of the torsion spring are respectively in limiting sleeve joint on the positioning columns.
