The hinge structure includes a first pivoting member, a second pivoting member, and a third pivoting member. The first pivoting member has a first fixing portion fixed to the first body and a first winding portion extending from the first fixing portion. The second pivoting member has a second fixing portion fixed to the first body and a second winding portion extending from the second fixing portion. The third pivoting member is disposed on the second body and has a shaft. The first winding portion and the second winding portion respectively wind around the shaft. The first fixing portion and the second fixing portion are located at opposite sides of the shaft. An electronic device is also provided. ## Claims ### Claim 1 A hinge structure suited for connecting between a first body and a second body so that the first body and the second body can rotate in relative to each other, the hinge structure comprising: a first pivoting member having a first fixing portion and a first winding portion extending from the first fixing portion, the first fixing portion fixed on the first body; a second pivoting member having a second fixing portion and a second winding portion extending from the second fixing portion, the second fixing portion fixed on the first body; and a third pivoting member disposed on the second body, the third pivoting member having a shaft, wherein the first winding portion and the second winding portion respectively wind around the shaft, and the first fixing portion and the second fixing portion are located at two opposite sides of the shaft. ### Claim 2 (depends on 1) The hinge structure as recited in claim 1, wherein the first winding portion has a first gap, the second winding portion has a second gap, and the first gap and the second gap are located at the two opposite sides of the shaft. ### Claim 3 (depends on 1) The hinge structure as recited in claim 1, wherein a direction of the first winding portion winding around the shaft is the same as a direction of the second winding portion winding around the shaft. ### Claim 4 (depends on 1) The hinge structure as recited in claim 1, wherein a direction of the first winding portion winding around the shaft is opposite to a direction of the second winding portion winding around the shaft. ### Claim 5 (depends on 1) The hinge structure as recited in claim 1, wherein the first pivoting member or the second pivoting member further comprising at least one third winding portion adjacent to the first winding portion or the second winding portion, and a direction of the third winding portions winding around the shaft is the same as or different from that of the first winding portion of the second winding portion. ### Claim 6 (depends on 1) The hinge structure as recited in claim 1, wherein the third pivoting member further comprises a third fixing portion fixed on the second body and connected to an end of the shaft, and the shaft is pivoted at a side edge of the third fixing portion. ### Claim 7 (depends on 6) The hinge structure as recited in claim 6, wherein the third fixing portion and the first fixing portion or the second fixing portion are located at a same side of the shaft. ### Claim 8 An electronic device comprising: a first body; a second body; a hinge structure connected between the first body and the second body, the hinge structure comprising: a first pivoting member having a first fixing portion and a first winding portion extending from the first fixing portion, the first fixing portion fixed on the first body; a second pivoting member having a second fixing portion and a second winding portion extending from the second fixing portion, the second fixing portion fixed on the first body; and a third pivoting member disposed on the second body, the third pivoting member having a shaft, wherein the first winding portion and the second winding portion respectively wind around the shaft, and the first fixing portion and the second fixing portion are located at two opposite sides of the shaft. ### Claim 9 (depends on 8) The electronic device as recited in claim 8, wherein the second body comprises: a main body; and a side arm having a first end and a second end, the second end pivoted to the main body, the third pivoting member disposed at the second end. ### Claim 10 (depends on 9) The electronic device as recited in claim 9, wherein the third pivoting member further comprises a third fixing portion fixed on the second end of the side arm, the shaft extends from the second end towards the first body, and the third fixing portion and the first fixing portion or the second fixing portion are located on a same side of the shaft. ### Claim 11 (depends on 8) The electronic device as recited in claim 8, wherein the first winding portion has a first gap, the second winding portion has a second gap, and the first gap and the second gap are located at the two opposite side of the shaft. ### Claim 12 (depends on 8) The electronic device as recited in claim 8, wherein a direction of the first winding portion winding around the shaft is the same as a direction of the second winding portion winding around the shaft. ### Claim 13 (depends on 8) The electronic device as recited in claim 8, wherein a direction of the first winding portion winding around the shaft is opposite from a direction of the second winding portion winding around the shaft. ### Claim 14 (depends on 8) The electronic device as recited in claim 8, wherein the first pivoting member or the second pivoting member further comprises at least one third winding portion adjacent to the first winding portion or the second winding portion, and a direction of the third winding portions winding around the shaft is the same or different from that of the first winding portion or the second winding portion.
