The plurality of sidewalls 183 are of a high friction coefficient and are capable of maintaining the edges of the electronic device 200 in the latching chamber 185. In the embodiment, the positing sleeve 18 is made of silica gel.
The sealing cover 19 is received in the locking hole 1331 and abuts against the second resisting portion 1335 to seal the locking hole 1331. In the embodiment, the sealing cover 19 is circular and made of silica gel.
In assembling, the positioning sleeve 18 is received in the latching groove 1151 with the latching chamber 185 toward outside. The plurality of anti-skid members 17 are received in the arcuate grooves 119, 1313 with the frictional surface 171 deviating from the arcuate grooves 119, 1313.
Referring to FIG. 7, the resisting plate 16 is sleeved on the locking portion 117 via the center hole 161. A force is applied to bend the plurality of claws 1175 to gather inwardly, and the locking portion 117 extends into the locking hole 1331 of the support member 13. Releasing the plurality of claws 1175 until the plurality of claws 1175 reach the first resisting portion 1333, thus the plurality of claws 1175 return back and resist the first resisting portion 1333 to prevent the locking portion 117 from detaching from the locking hole 1331. The pivotal member 15 extends into the locking hole 1331 and the receiving hole 1171, the engaging portion 151 engages in the locking portion 117. The driving groove 1531 of the adjusting portion 153 is driven by a tool (not shown), the pivotal member 15 is rotated, then the engaging portion 151 resists the plurality of claws 1175 to bend toward and block the first resisting portion 1333 tightly. The locking portion 117 outwardly extrudes from the sidewalls of the engaging portion 151 to adjust the friction force between the locking portion 117 and the inner sidewalls of the locking hole 1331. The sealing cover 19 is received in the locking hole 1331 and abuts against the second resisting portion 1335 to seal the locking hole 1331. Both of the two support assemblies 10 are assembled in the same way, thus completing the assembly of the support mechanism 100.
When in use, the two support assemblies 10 are symmetrically aligned, the support member 13 is parallel to and positioned on a desk with the plurality of anti-skid members 17. The adjustable member 11 is rotated relative to the support member 13 to a predetermined angle, and opposite edges of the electronic device 200 are received in the latching chambers 185 of the two support assemblies 10, thus the electronic device 200 is maintained in the positioning sleeve 18 via the plurality of sidewalls 183. Referring to FIG. 5, the support mechanism 100 is shown in a first support state. In this state, the support end 113 is away from the desk and the electronic device 200 is substantially perpendicular to the desk.
Referring to FIG. 6, the support mechanism 100 is shown in a second support state. In this state, the electronic device 200 is maintained in the positioning sleeve 18 via the plurality of sidewalls 183, the resisting end 131 of the support member 13 and the support end 113 of the adjustable member 11 abut against the desk to maintain the support mechanism 100. The connecting end 133 of the support member 13 and the joint end 111 of the adjustable member 11 are away from the desk.
In both support states, the display angle of the electronic device 200 can be adjusted by rotating the adjustable member 11 relative to the support member 13. The friction force between the locking member 117 and the inner sidewall of the locking hole 1331 can be adjusted by rotating the pivotal member 15.
Referring to FIGS. 1 through 6, to fold the support mechanism 100, the two support assemblies 10 are pulled away from each other to release the electronic device 200. The adjustable member 11 is rotated relative to the support member 13 until on a plane with the support member 13. The protrusion 137 of one of the two support assemblies 10 is received in the latching chamber 185 of another of the two support assemblies 10, thus the two support assemblies 10 are on the same plane. The support mechanism 100 is then folded for carrying.
The support mechanism 100 can be easily folded and is convenient to carry. The support mechanism 100 includes only two adjustable members 11 and two support members 13, thus the structure and manufacturing of the support mechanism 100 is very simple. When the adjustable member 11 and the support member 13 are worn, and the friction between the locking hole 1331 and the locking portion 117 is decreased. By driving the adjusting portion 153 of the pivotal member 15 to rotate between the locking hole 1331 and the locking portion 117 the friction can be increased. Thus, the support mechanism 100 can have relatively long service life. Moreover, the position sleeve 18 and the plurality of anti-skid members 17 are made of silica gel, it results in a soft feel in the hand and the support mechanism 100 can be located on surfaces which are slightly irregular and even tilted. The sealing covers 19 seal the locking holes 1331 to prevent the pivotal members 15 from being corroded.
The plurality of anti-skid members 17 may be formed in the arcuate grooves 119, 1313 by injection molding. The positioning sleeve 18 may be omitted and the adjustable member 11 includes a plurality of claws made of sticky material on the side wall of the latching groove 1151.
Finally, while various embodiments have been described and illustrated, the disclosure is not to be construed as being restricted thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
