Abstract

A hinge module for an electronic device includes a main body and an upper cover. The hinge module includes a biaxial hinge and a pad. The biaxial hinge includes a first rotary shaft, a second rotary shaft and a connecting member. One end of the first rotary shaft is fixed to the main body, and another end of the first rotary shaft being pivotally connected with the connecting member. One end of the second rotary shaft is fixed to the upper cover, and another end of the second rotary shaft is pivotally connected with the connecting member. The pad is disposed at the connecting member of the biaxial hinge. When the upper cover rotates with respect to the main body, the connecting member and the pad rotates using the first rotary shaft as a rotation axis.

Claims

1. A hinge module for an electronic device, the electronic device comprising a main body and an upper cover, the hinge module comprising:

a biaxial hinge comprising a first rotary shaft, a second rotary shaft and a connecting member, one end of the first rotary shaft being fixed to the main body, another end of the first rotary shaft being pivotally connected with the connecting member, one end of the second rotary shaft being fixed to the upper cover, another end of the second rotary shaft being pivotally connected with the connecting member; and

a pad disposed at the connecting member of the biaxial hinge, when the upper cover rotates with respect to the main body, the connecting member and the pad rotates using the first rotary shaft as a rotation axis.

2. The hinge module according to claim 1, wherein the connecting member comprises a housing, and the pad is disposed at the housing of the connecting member.

3. The hinge module according to claim 2, wherein the pad covers one side of the housing corresponding to the first rotary shaft.

4. The hinge module according to claim 2, wherein the housing and the pad are integrally formed, and material of the housing and the pad comprise rubber or plastic.

5. The hinge module according to claim 2, wherein the connecting member has a threaded hole, the housing has a through hole, when the housing is disposed around the biaxial hinge, a screw passes the through hole of the housing and is locked at the threaded hole of the connecting member.

6. The hinge module of claim 1, wherein the pad has a U-shape cross section and covers a portion of the first rotary shaft.

7. An electronic device, comprising:

a main body;

an upper cover; and

a hinge module, the hinge module comprising;

a biaxial hinge comprising a first rotary shaft, a second rotary shaft and a connecting member, one end of the first rotary shaft being fixed to the main body, another end of the first rotary shaft being pivotally connected with the connecting member, one end of the second rotary shaft being fixed to the upper cover, another end of the second rotary shaft being pivotally connected with the connecting member; and

a pad disposed at the connecting member of the biaxial hinge, when the upper cover rotates with respect to the main body, the connecting member and the pad rotates using the first rotary shaft as a rotation axis.

8. The electronic device according to claim 7, wherein the connecting member comprises a housing, and the pad is disposed at the housing of the connecting member.

9. The electronic device according to claim 8, wherein the pad covers one side of the housing corresponding to the first rotary shaft.

10. The electronic device according to claim 8, wherein the housing and the pad are integrally formed, and material of the housing and the pad comprise rubber or plastic.

11. The electronic device according to claim 8, wherein the connecting member has a threaded hole, the housing has a through hole, when the housing is disposed around the biaxial hinge, a screw passes the through hole of the housing and is locked at the threaded hole of the connecting member.
