Description
Technical field
A kind of controlling organization for electronic equipment support foot rest is the utility model is related to, it is more particularly to a kind of to determine angle certainly
The support frame moved and withdrawn.
Background technology
Tablet personal computer or intelligent mobile phone etc mobile electronic equipment generally have to use by both hands grip, hold very much
Sense of fatigue is also easy to produce, if place it in position on above-knee or table, the phenomenon generation for rocking sliding is also often had, to making
The operation of user causes to perplex.Solves this problem, most common mode is that support feet is installed on mobile electronic equipment
Frame so that such mobile device is to support into certain angle is erected using foot stool, turns into more convenient stabilization and labour-saving manipulation
State.
The existing support leg frame structure being used in electronic equipment is mostly that support frame one end positions with electronic equipment pivot joint,
The other end is then movable force side, and whole foot stool can develop the back side for being received in electronic equipment when not in use, when in use, with foot stool
Pivot joint positioning end is opened into a variety of support angles for action axle center.
But existing such support foot rest located at mobile electronic equipment is when not in use, is that electronics is close proximity in a manner of developing
The back side of equipment, gap between the two is very small, under the more thick situation of user's finger, by support foot rest never
When being opened to using prelocalization state up to the support angle position of a setting of opening, it is operationally very troublesome and inconvenient；
Conversely, withdrawal positioning of such support foot rest after different support angle uses are opened to is also very bothersome.
