Abstract

A hinge module includes a housing and at least one carrying assembly. The housing includes two accommodation spaces. The at least one carrying assembly is disposed at the housing and includes a torque element, two rotation shafts and two brackets. The torque element is disposed in one of the accommodation spaces. The two rotation shafts pass through the torque element. The two brackets are respectively connected to the two rotation shafts and located outside the housing. Each bracket is adapted to rotate along with the corresponding rotation shaft and rotate relative to the torque element.

Claims

1. A hinge module, comprising:

a housing, having two accommodation spaces; and

at least one carrying assembly, disposed at the housing and the at least one carry assembly comprising;

a torque element, disposed in one of the accommodation spaces;

two rotation shafts, passing through the torque element; and

two brackets, respectively connected to the two rotation shafts and located outside the housing,

wherein each of the brackets is adapted to rotate along with the corresponding rotation shaft and rotates relative to the torque element.

2. The hinge module as claimed in claim 1, wherein the number of the at least one carrying assembly is two, and the two carrying assemblies are respectively disposed in the two accommodation spaces of the housing.

3. The hinge module as claimed in claim 1, wherein an engagement bevel surface is formed in each of the accommodation spaces, and the at least one carrying assembly and the corresponding engagement bevel surface tightly fit with each other.

4. The hinge module as claimed in claim 1, wherein a fixing structure is formed in each of the accommodation spaces, and the at least one carrying assembly and the corresponding fixing structure tightly fit with each other.

5. The hinge module as claimed in claim 1, further comprising a positioning pillar, disposed in the housing, and two end portions of the positioning pillar respectively extending into the two accommodation spaces.

6. The hinge module as claimed in claim 5, wherein the at least one carrying assembly comprises a positioning plate sleeved on the two rotation shafts and accommodating one of the end portions of the positioning pillar.

7. The hinge module as claimed in claim 1, wherein the at least one carrying assembly comprises a position-limiting plate sleeved on the two rotation shafts and having a first stopper and a second stopper, each of the rotation shafts has a bump, when the two brackets are closed relative to each other, the two bumps respectively abut against the first stopper and the second stopper, and when the two brackets are expanded relative to each other, the two bumps respectively depart away from the first stopper and the second stopper.

8. The hinge module as claimed in claim 1, wherein two openings of the two accommodation spaces are respectively formed at two opposite sides of the housing.

9. An electronic apparatus, comprising:

two bodies; and

two hinge modules, disposed between the two bodies, and each of the hinge modules comprising;

a housing, having two accommodation spaces; and

at least one carrying assembly, disposed at the housing and the at least one carry assembly comprising;

a torque element, disposed in one of the accommodation spaces;

two rotation shafts, passing through the torque element; and

two brackets, respectively connected to the two rotation shafts and located outside the housing, wherein the two bodies are respectively connected to the two brackets,

wherein each of the brackets is adapted to rotate along with the corresponding rotation shaft and rotate relative to the torque element to drive the two bodies to expand or close relative to each other.

10. The electronic device as claimed in claim 9, wherein the number of the at least one carrying assembly is two, and the two carrying assemblies are respectively disposed in the two accommodation spaces of each of the housings.

11. The electronic device as claimed in claim 10, further comprising a bus cable, disposed in the two bodies and located between the two hinge modules.

12. The electronic device as claimed in claim 9, wherein the number of the at least one carrying assembly of one of the hinge modules is two, and the two carrying assemblies are respectively disposed in the two accommodation spaces of the housing, wherein the number of the at least one carrying assembly of the other one of the hinge modules is one, and the carrying assembly is disposed in one of the accommodation spaces of the housing.

13. The electronic device as claimed in claim 12, further comprising a cable, disposed in the two bodies and located adjacent to the other one of the two hinge modules, and the cable being partially disposed in the other one of the accommodation spaces of the housing.

14. The electronic device as claimed in claim 9, wherein an engagement bevel surface is formed in each of the accommodation spaces, and an interference portion of the at least one carrying assembly and the corresponding engagement bevel surface tightly fitting with each other.

15. The electronic device as claimed in claim 9, wherein a fixing structure is formed in each of the accommodation spaces, and an interference portion of the at least one carrying assembly and the corresponding fixing structure tightly fitting with each other.

16. The electronic device as claimed in claim 9, further comprising two positioning pillars, respectively disposed in the two housings, and two end portions of each of the positioning pillars respectively extending into the corresponding two accommodation spaces.

17. The electronic device as claimed in claim 16, wherein the at least one carrying assembly comprises a positioning plate sleeved on the two rotation shafts and accommodating one of the end portions of the positioning pillars.

18. The electronic device as claimed in claim 9, wherein the at least one carrying assembly comprises a positioning plate sleeved on the two rotation shafts and having a first stopper and a second stopper, each of the rotation shafts has a bump, when the two brackets are closed relative to each other, the two bumps respectively abut against the first stopper and the second stopper, and when the two brackets are expanded relative to each other, the two bumps respectively depart away from the first stopper and the second stopper.
