1. Technical Field
The present disclosure related to support mechanisms and, particularly, to a support mechanism for supporting an electronic device.
2. Description of Related Art
Many hand-held electronic devices, such as mobile phones or tablet computers, are now commonly used and supported by some included mechanism in an upright position on a support surface. However, many support mechanisms are not adjustable and so may not provide the best viewing angle in various circumstances for different users.
Therefore, there is room for improvement in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

The adjusting assembly 27 includes a sliding member 270 and a driving member 272. The sliding member 270 includes two paralleled extendable legs 2701 corresponding to the two first slots 232, a connection post 2703 for connecting the two extendable legs 2701 to the adjusting assembly 27, and a toothed post 2705 connected to the connection post 2703 and corresponding to the third slot 234. The extendable legs 2701, the connection post 2703, and the post 2705 are coplanar. The toothed post 2705 defines a toothed surface 2707. Each extendable leg 2701 is capable of sliding in a corresponding one of the first slots 232 to partly extend out of the second support member 23. The connection post 2703 is capable of sliding in the second slot 233. The toothed post 2705 is capable of sliding in the third slot 234. The width of the connection post 2703 is less than that of the second sliding slot 233, such that the extendable legs 2701 can slide in the corresponding slots 232 to extend through the sidewall 231 to extend out of the second support member 23 when the toothed post 2705 is driven to slide in the third sliding slot 234. As a result, the length of the part of each extendable leg 2701 extending out of the second support member 23 is adjustable.
The driving member 272 includes a knob 2721, a gear member 2723 corresponding to the toothed post 2705, and a connection shaft 2722 for connecting the knob 2721 to the gear member 2723. The gear member 2723 meshes with the toothed post 2705 to drive the toothed post 2705 to slide along the third sliding slot 234 when the knob 2721 is rotated.
The restricting member 29 is fixed to the second support member 27 to restrict the adjusting assembly 27 from moving away from the second support member 23. The restricting member 29 is substantially rectangular and includes an engaging surface 290 corresponding to the assembly surface 230 of the second support member 23. The engaging surface 290 defines a receiving slot 292 for rotatably receiving the shaft 2722 and the gear member 2723.
In assembly, the protrusions 218 are received in the corresponding opening 212 by shafts 214 being received in the corresponding blind hole 219, thus the base 215 is pivotably connected to the main body 210. The sliding member 270 is mounted to the second support member 23 with the extendable leg 2701, the connection post 2703, and the toothed post 2705 being respectively received in the first sliding slot 232, the second sliding slot 233, and the third slot 234. The driving member 272 is connected to the sliding member 270 with the gear member 2723 meshing with the toothed surface 2707. The restricting member 29 is mounted to the second support member 23 with the engaging surface 290 abutting the assembly surface 230 and the receiving slot 292 receiving the gear member 2723 and the connection shaft 2722 therein.
To use the electronic device 1, the electronic device 1 can be located on the base 215 and received in the clearance defined between the contacting surface 211 and the block 217. In this state, the electronic device 1 can be adjustably standing upright on a horizontal surface to offer a good viewing angle to the user, and the extendable legs 2701 are completely received in the corresponding first slots 232.
When the viewing angle of the electronic device 1 needs to be adjusted, the knob 2721 is rotated in a first direction or in a second direction reverse to the first direction, and each extendable leg 2701 is driven to slide out of or slide into the second support member 23. As a result, the length of the part of each extendable leg 2701 extending out of the second support member 23 is changeable, the distance between the side wall 231 and a support surface is also changed, and the electronic device 1 can be viewed from different angles. When the connection post 2703 slides in the second sliding slot 233 to abut a slot wall (not labeled) which partially surrounds the second sliding slot 233 and is adjacent to the sidewall 231, the extendable legs 2701 are restricted from further sliding relative to the second support member 23, and the viewing angle of the electronic device 1 is thereby set.
It is to be understood, however, that even though information and the advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the present embodiments, the disclosure is illustrative only; and that changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
