Friction shaft hinge of the present utility model is particularly suited for the supporting structure being applied to the digital product such as panel computer and large scale mobile phone, provides enough large support force.
For the mobile electronic product terminal of application above-mentioned linking type friction shaft hinge, its main body and Gai Ke are connected with moving runner 92 with shell 8 respectively, or the main body of mobile electronic product terminal is connected with moving runner 92 with shell 8 respectively with support.
1. the utility model in an initial condition, and moving runner 91 and the second axle 2, second cam and the second axle 2 are all coordinated by flat position, welds between the two pieces coordinated after assembling, and in movement process, these three components can be considered one; Retainer ring 93 is assembled by the projection of both sides and shell 7, retainer ring 93 and shell 7 geo-stationary in movement process; Intermediate cam 4 and the 3rd axle 3 are coordinated by flat position, and intermediate cam 4 can only along the axially lower slider of the 3rd axle 3.Intermediate cam 4 is subject to the power of the axis of the spring 7 that conjunction 5 transmits.In this case, intermediate cam 4 compresses the second cam inner ring camming surface and also namely controls cooperating structure 61, and moving runner 92 is subject to the torsion of torsion spring 91 simultaneously.Under the acting in conjunction of each power, each parts remain static.
2. automatically open (the first work mated condition): by moulded rod 8, intermediate cam 4 pushes away downwards by depression bar 8 vertically, until intermediate cam 4 gear teeth are separated with control cooperating structure 61 gear teeth, moving runner 92, second cam 6 and the second axle 2 rotate Y ° to the position of presetting under the effect of torsion spring torsion, now torsion spring 91 pretightening force discharges completely, and intermediate cam 4 upwards pushes away by spring vertically, conjunction 4 and control cooperating structure 61 gear teeth meshing.Regulated by parameter, hinge (mobile electronic product terminal) can be opened to the most frequently used angle of terminal client by moulded rod.
3. Free-stop angle free adjustment (the second work mated condition): the second axle 2 in linking type friction shaft hinge is connected by flat position with the second cam 6.After second cam 6 and conjunction 4 engage, rotary motion wheel 92, power just can pass through the second axle 2, second cam 6 and intermediate cam 4, is passed to the first axle 1; First axle 1 coordinates with friction sleeve 10, just has frictional force and produce when relatively rotating between two pieces; When moving runner 92 rotates within the scope of Z ° ~ X °, all have the feel of freely stopping function (Free Stop).
4, closing process:
Drive wheel convolution to (the second work mated condition) during Y °, then continues to rotate the ending phase (the first work mated condition) by entering closing process.Because intermediate cam 4 does not turn, second cam 6 is turning, and when moving runner 92 circles round extremely close to (the second work mated condition) during Y °, the second cam 6 starts to drive intermediate cam 4 axially to retreat, second cam 6 and conjunction 4 are thrown off gradually, enter the first work mated condition.
Continue rotary motion wheel, now friction sleeve is inoperative, and torsion spring is in accumulation of energy, and the ending phase of closing process only need overcome the reaction force of torsion spring, until to close stance (the first work mated condition).
