Description

BACKGROUND

1. Technical Field

The present disclosure relates to hinge assemblies.

2. Description of Related Art

A conventional hinge assembly usually includes a first connecting member and a second connecting member. The engagement between the first connecting member and the second connecting member is usually a threaded engagement. In assembling such hinge assembly, it is often not an easy task to cause the first connecting member to be engaged with the second connecting member via the threaded engagement.

DETAILED DESCRIPTION

Referring to FIG. 1, an electronic device 100 with a hinge assembly 10 is illustrated. The electronic device 100 can be a notebook computer, or a desk lamp, etc. In the embodiment, the electronic device 100 is a desk lamp. The electronic device 100 includes the hinge assembly 10, a lamp 12, and a stand 14. The hinge assembly 10 is configured for connecting the lamp 12 to the stand 14.

Referring also to FIGS. 2-3, the hinge assembly 10 includes a first connecting member 20, a second connecting member 30, a first fixing member 40, and a second fixing member 50.

The first connecting member 20 includes a first connecting portion 22 and a first fixing portion 24. The first connecting portion 22 is connected to the lamp 12. The first fixing portion 24 defines a first shaft hole 240. The first fixing member 40 can extend through the first shaft hole 240.

The second connecting member 30 includes a second connecting portion 32 and a second fixing portion 34. The second connecting portion 32 is connected to the stand 14. The second fixing portion 34 defines a second shaft hole 340. The second fixing member 50 can extend through the second shaft hole 340.

The first fixing member 40 includes a first fixing shaft 42, a first head portion 43, and a first magnet 44. The diameter of the first fixing shaft 42 is less than that of the first shaft hole 240 and the second shaft hole 340, thus the first fixing shaft 42 can extend through the first shaft hole 240 and be received in the second shaft hole 340. The first head portion 43 is secured to one end of the first fixing shaft 42. The diameter of the first head portion 43 is greater than that of the first shaft hole 240, thus the first head portion 43 cannot pass through the first shaft hole 240. The first magnet portion 44 is attached to another opposite end of the first fixing shaft 42 using adhesive material. The south pole of the first magnet 44 is attached to the opposite end of the first fixing shaft 42. In the embodiment, the first magnet 44 is a permanent magnet.

The second fixing member 50 includes a second fixing shaft 52, a second head portion 53, and a second magnet 54. The diameter of the second fixing shaft 52 is slightly less than that of the second shaft hole 340 and the first shaft hole 240, thus the second fixing shaft 42 can pass through the second shaft hole 340 and the first shaft hole. The second fixing shaft 52 defines a first through hole 520 extending along the axis of the second fixing shaft 52. The diameter of the first through hole 520 is larger than that of the first fixing shaft 42, thus the first fixing shaft 42 can be received in the first through hole 520. The second head portion 53 is secured to one end of the second fixing shaft 52. The diameter of the second head portion 53 is greater than that of the second shaft hole 340, thus the second head portion 44 cannot extend or pass through the second shaft hole 340. The second magnet 54 is attached to another opposite end of the second fixing shaft 52 using adhesive material. The south pole of the second magnet 54 is attached to the opposite end of the second connecting member 30. The second magnet 54 defines a second through hole 540. The diameter of the second through hole 540 is equal to that of the first through hole 520, thus the first fixing shaft 42 can pass through the second through hole 540. The second magnet 54 is a permanent magnet.

FIG. 4 is employed to illustrate the procedure of assembling the hinge assembly 10. The procedure includes the following steps: inserting the first fixing member 40 into the first connecting member 20; inserting the second fixing member 50 into the second connecting member 30; and inserting the first fixing member 40 into the second fixing member 30. During the process of inserting the first fixing member 40 into the second fixing member 30, the first fixing member 40 is repelled by a first magnetic force between the first magnet 44 and the second magnet 54 to block the insertion of the first fixing member 40 because the first magnet 44 and the second magnet 44 are oriented with their north poles toward each other. After inserting the first fixing member 40 into the second fixing member 30 by overcoming the first magnetic force, the first fixing member 40 is pulled by a second magnetic force to stop the first fixing member from sliding out from the second fixing member 50 because when the first magnet 44 passes together with the first fixing member 40, the south poles of the first magnet 44 and the second magnet 54 repel each other and force the first fixing member 40 to engage with the second fixing member 50. Therefore, the first fixing member 40 engages with the second fixing member 50 under the second magnetic force between the first magnet 44 and the second magnet 54. Therefore engagement of the parts of the present hinge 10 relatively easy.

Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
