The invention relates to an electronic device, and in particular, to an electronic device with a support mechanism to adjust a body without a hinge.
In a liquid crystal display, a screen angle is typically adjusted by a hinge. Since the hinge is manufactured by a specialized factory to obtain a required torque, mass production is difficult, thus increasing cost.
An electronic device with a support mechanism to adjust a body without a hinge is provided. An exemplary embodiment of an electronic device comprises a body, a rotatable member, a support, a friction member, and a base. The rotatable member is disposed on the body. The support is combined with the rotatable member. The rotatable member rotates with respect to the support. The friction member is combined with the rotatable member, and comprises a first circular arc surface. The base is combined with the friction member, and comprises a second circular arc surface corresponding to the first circular arc surface. The support is disposed on the base. The first circular arc surface slidably abuts the second circular arc surface. The body is kept at a predetermined position by friction generated by the first circular arc surface abutting the second circular arc surface.
The electronic device further comprises a combining member, a pad, and a rotary shaft. The combining member combines the base and the friction member so that the first circular arc surface closely abuts the second circular arc surface. The combining member is a screw passing through the base to be combined with the friction member. The base comprises a slot in which the screw is moveable. The pad is located between the combining member and the base. The rotary shaft combines the support and the rotatable member. The rotatable member comprises a first through hole. The support comprises a second through hole corresponding to the first through hole. The rotary shaft passes through the first and second through holes.
Moreover, the rotatable member comprises a hollow portion. The friction member comprises a protrusion inserted into the hollow portion to combine the rotatable member and the friction member.
The rotatable member and the body may be integrally formed into a single piece. The support and the base may also be integrally formed into a single piece. The friction member may comprise polycarbonate resin, polyethylene resin, or poly acetal resin.
Note that the electronic device may be a display, and the body may be a screen.
A support mechanism for supporting an object is provided. An exemplary embodiment of a support mechanism comprises a rotatable member, a support, a friction member, and a base. The rotatable member is disposed on the object. The support is combined with the rotatable member. The rotatable member rotates with respect to the support. The friction member is combined with the rotatable member, and comprises a first circular arc surface. The base is combined with the friction member, and comprises a second circular arc surface corresponding to the first circular arc surface. The support is disposed on the base. The first circular arc surface slidably abuts the second circular arc surface. The object is kept at a predetermined position by friction generated by the first circular arc surface abutting the second circular arc surface.

a-3b depict an embodiment of an electronic device 1 comprising a body 10, a rotatable member 20, a support 30, a friction member 40, a base 50, a combining member 60, and a rotary shaft 80. The rotatable member 20, the support 30, the friction member 40, the base 50, the combining member 60, and the rotary shaft 80 substantially constitute an embodiment of a support mechanism. While the electronic device 1 and the body 10 are a display and a screen respectively in

The base 50 serves as a bottom of the entire electronic device 1, and comprises a second circular arc surface 51, corresponding to the first circular arc surface 41, to provide a contact area for the friction member 40. The base 50 further comprises a slot 52 for restraining the inclined angle of the body 10 during the rotation of the rotatable member 20 to adjust the body 10 within a predetermined range.
The combining member 60 may be a screw passing through the slot 52 of the base 50 to be combined with the friction member 40, as shown in
The rotary shaft 80 serves as an axis during rotation of the body 10. Referring to
As previously described, since the first circular arc surface 41 closely abuts the second circular arc surface 51, the friction is generated between the base 50 and the friction member 40. Thus, the body 10 may be rotated with respect to the support 30 via the rotatable member 40 by the friction between the base 50 and the friction member 40.

As previously described, an embodiment of the electronic device comprises the friction member and corresponding members to provide the friction replacing the torque of the conventional hinge. Thus, assembly may be easier, and cost may be decreased. Furthermore, when a force exceeding the friction is applied on the body, the body may be easily adjusted to the predetermined angle.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
