For example, when the function module 120 is a battery, the power of the function module 120 can be transmitted to the electronic device. When the function module 120 is a sensing component, the signal sensed by the function module 120 can be transmitted to the electronic device for discriminating by electronic components (not shown) in the electronic device.

4 is a cross-sectional view of the wearable functional component of FIG. 1 taken along line I-I. Figure 5 is a schematic illustration of the flexible printed circuit board and sleeve of Figure 3 in an unfolded state. Fig. 6 is a schematic view showing the flexible printed circuit board and the sleeve of Fig. 3 in a bent state. Referring to FIG. 4, FIG. 5 and FIG. 6, when the body 110 rotates around the rotating shaft 140 and assumes an unfolded state or a bent state (as shown in FIGS. 1 and 2), the rotating shaft 140 slides relative to the sleeve 130. Inside the opening 132, the sleeve 130 supports the flexible printed circuit board 150.

In detail, after the rotating shaft 140 passes through the opening portion 132 of the sleeve 130, since the space formed by the opening portion 132 of the sleeve 130 allows the rotating shaft 140 to slide relative to the sleeve 130, when the body 110 is centered on the rotating shaft 140, When rotated, the flexible printed circuit board 150, which is slidable by the sleeve 130 and located at the pivotal connection of the body 110, can be effectively supported by the sleeve 130. Thereby, the flexible printed circuit board 150 can be continuously bent to cause fatigue damage, thereby causing a risk of breakage of a line (not shown) on the flexible printed circuit board 150, and the power or signal of the function module 120 is caused. Cannot be transferred to an electronic device. Accordingly, the flexible printed circuit board 150 has a better life and ensures the reliability of the wearable functional component 100.

Referring to FIG. 3 and FIG. 4, the flexible printed circuit board 150 of the present embodiment. The plurality of line portions 152, the plurality of first electrode portions 154, the plurality of second electrode portions 156, and the bent portion 158 are included. The line portion 152 has a plate shape and is provided with a line (not shown) on the surface 152a thereof, and the functional module 120 bears against the surface 152a of the line portion 152. Each of the first electrode portions 154 and each of the second electrode portions 156 is a strip-like structure extending from the line portion 152 , and the strip structures are electrically connected to the functional module 120 . Each of the bent portions 158 connects the two adjacent line portions 152 and covers the corresponding sleeve 130. Further, after the first electrode portions 154 and the second electrode portions 156 abut against the two electrodes (not shown) of the corresponding functional module 120, the first electrode portion 154 and the second electrode portions 156 are connected by the line of the line portion 152 and span the bend.

Referring to FIG. 3, FIG. 5 and FIG. 6, the top portion 158a of the bent portion 158 of the present embodiment has a spacing G1 between the surface 152a of the line portion 152, and the spacing G1 is floated to the sleeve relative to the bent portion 158. The curvature of the protrusion naturally formed on the circumference of the barrel 130 can change the curvature of the protrusion of the bent portion 158 via the movement of the rotating shaft 140 at the opening portion 132. In other words, when the body 110 transitions from the unfolded state to the bent state (please refer to FIGS. 1 and 2), the pitch G1 increases. Therefore, it is ensured that the flexible printed circuit board 150 is indeed supported when the sleeve 130 slides. Further, when the sleeve 130 is in the unfolded state or the bent state, each of the bent portions 158 is closely attached to the corresponding sleeve 130. Thereby, the sleeve 130 is not reliably supported by the flexible printed circuit board 150 due to manufacturing tolerances or assembly tolerances, and the degree of freedom of the body 110 can be increased.

Further, the opening portion 132 of the sleeve 130 of the present embodiment has an elliptical shape. Therefore, when the body 110 is rotated, the sleeve 130 is slidable along the first axis A1 (for example, in the up/down directions of FIGS. 5 and 6). According to this, the sleeve 130 rotates when the body 110 rotates There may be an adjustment margin in the axial direction.

Fig. 7 is a schematic view showing another embodiment of the flexible printed circuit board and the sleeve of Fig. 4 in an unfolded state. In the present embodiment, the opening portion 132a of the sleeve 130a is cam-shaped. Therefore, when the body 110 rotates, the sleeve 130a can slide along the first axis A1 (for example, the up/down direction of FIG. 7), and can also follow the second axis A2 (for example, the left/right direction of FIG. 7). )slide. Accordingly, the sleeve 130a can have an adjustment margin in both axial directions when the body 110 is rotated. However, the novel creation does not limit the shape of the opening, and the user can adjust the appropriate shape according to the actual product requirements.

Referring to FIG. 1 and FIG. 3 , in the embodiment, the wearable functional component 100 further includes a plurality of plate bodies 160 , wherein the plate body 160 is made of a waterproof material, and the functional module 120 is located between the body 110 and the plate body 160 . between. This configuration allows the wearable functional component 100 to have a waterproof function.

In summary, the sleeve of the present invention has an opening portion and is slidable relative to the sleeve when the shaft rotates. Thus, as the body rotates, the sleeve can slide and support the flexible printed circuit board. Thereby, the risk of the fatigue bending of the flexible printed circuit board and the breakage of the line on the flexible printed circuit board can be reduced, and the power or signal of the function module cannot be transmitted to the electronic device. Accordingly, the flexible printed circuit board has a better service life and ensures the reliability of the wearable functional component. Further, when the opening portion has an elliptical shape or a cam shape, the sleeve may have an axial or two axial adjustment margin. In addition, when the wearable functional component has a waterproof panel, the wearable functional component is waterproof.

Although the novel creation has been disclosed above by way of example, it is not intended to limit This new type of creation, any person with ordinary knowledge in the technical field, can make some changes and refinements without departing from the spirit and scope of this new creation. Therefore, the scope of protection of this new creation should be attached to the scope of patent application. The definition is final.
