Support assembly and digital photo frame using the same
A support assembly for a digital photo frame is provided. The support assembly comprises a base member, a pivot member, a support arm, a positioning structure, and a an elastic member. The base member comprises two side walls spaced from each other. The support arm comprises a connection end disposed between the two side walls and is rotatably attached to the base member via the pivot member. The connection end comprises a first surface and a second surface opposite to each other. The pivot member is attached across the two side walls. The positioning structure is disposed on the first surface and the side wall opposite the first surface and comprises a projection portion and at least two concave portions. The projection portion is capable of being received in the at least two concave portions, the two concave portions intersect to form an edge.
1. A support assembly for a digital photo frame, comprising:
a base member comprising two side walls spaced from each other;
a pivot member attached across the two side walls to the base member;
a support arm comprising a connection end disposed between the two side walls and rotatably attached to the base member via the pivot member, wherein the connection end comprises a first surface and a second surface opposite to each other;
a positioning structure disposed on the first surface and the side wall opposite the first surface, comprising a projection portion and at least two concave portions, wherein the projection portion is capable of being received in the at least two concave portions, the two concave portions intersect to form an edge; and
an elastic member retained by the pivot member and the second surface of the support arm, wherein the elastic member provides a spring force to urge the connection end of the support arm toward the side wall opposite the first surface;
wherein the projection portion is positioned on the side wall that is opposite the first surface, and the at least two concave portions are positioned on the first surface, the projection portion includes an upper cylindrical surface, a first lower inclined surface, and a second lower inclined surface, each of the at least two concave portions includes a cylindrical side surface, a first inclined surface, and a second inclined surface.
2. The support assembly according to claim 1 , wherein the elastic member is a coil spring.
3. The support assembly according to claim 2 , wherein the coil spring is placed onto the pivot member.
4. The support assembly according to claim 1 , wherein the base member is mounded on a back portion of the digital photo frame.
