A hinge module connected between a first body and a second body of an electronic device is provided. The hinge module includes a hinge connecting the first and the second bodies, a linking rod, and a sleeve pivoted to the second body. The linking rod has a first end connected to the first body and a second end slidably coupled into the sleeve. When the first and the second bodies are rotated by the hinge module, the first body drives the linking rod such that the second end slides in the sleeve and drives the sleeve to rotate relative to the second body. Inner wall of the sleeve has at least one interfering section. When the second end moves onto the interfering section, the linking rod is interfered to the sleeve, such that the first body is supported by the hinge module and opened relative to the second body. |

1. A hinge module, connected between a first body and a second body of an electronic device, the first body and the second body relatively rotating via the hinge module to be folded or unfolded with each other, and a surface of the second body facing the first body in a folded state, the hinge module comprising:
a hinge connecting the first body and the second body;
a linkage assembly having a first linking rod and a second linking rod, wherein the first linking rod has a first end and a second end, the first end is connected to the second linking rod, and the second linking rod is connected to the first body with an end opposite to the first linking rod;a sleeve pivoted to the second body, the second end of the first linking rod slidably coupled into the sleeve, and the first linking rod and the sleeve being inclined to and submerged under the surface of the second body in the folded state; andan elastic member connected between the sleeve and the first linking rod,wherein the first linking rod and the sleeve are driven by the first body, such that the first linking rod and the sleeve move to and are horizontal to the surface of the second body when the electronic device is transformed from the folded state to a first unfolded state, and the elastic member is deformed by the sliding motion of the first linking rod relative to the sleeve,wherein the first linking rod and the sleeve are driven by the first body, such that the first linking rod and the sleeve protrude to and are inclined to the surface of the second body when the electronic device is transformed from the first unfolded state to a second unfolded state by a restoring force of the deformed elastic member,wherein a first angle is included between the first body and the second body when the electronic device is in the first unfolded state, a second angle is included between the first body and the second body when the electronic device is in the second unfolded state, and the second angle is greater than the first angle,wherein an inner wall of the sleeve has at least one interfering section, and the first body drives the first linking rod to move and interfere with the interfering section when the electronic device is in the second unfolded state, such that the first body is supported by the hinge module,wherein the inner wall of the sleeve has a sliding section located between a bottom wall and the interfering section, an inner diameter of the sleeve located at the sliding section is greater than an inner diameter of the sleeve located at the interfering section, and the first linking rod has a stopping portion located at the second end wherein the stopping portion is slidably coupled to the sliding section,wherein an outer diameter of the stopping portion is greater than the inner diameter of the sleeve located at the interfering section so as to restrict the stopping portion to slide in the sliding section. |
