Concrete, as shown in Figure 2, in embodiment provided by the invention, have employed outer gearing intermittent gearing mechanism, wherein, the first driving shaft 1 is coaxially provided with the first driving gear 11; Second driving shaft 2 is coaxially provided with the second driving gear 21; STATEMENT OF FEDERALLY SPONSORED comprises: the first equipment gear 3 and second equipment gear 4 that can be meshed with it; It should be noted that, in the present embodiment, the first driving gear 11, second driving gear 21, first equipment gear 3 and the second equipment gear 4 are the partial gear of outer gearing, and fix its axle center by axle center locating piece; In other embodiments, also can adopt internal messing intermittent gearing mechanism, or other be rotationally connected mode, the engagement system namely between gear is not limited only to this.
Further, first driving gear 11 can be meshed with the first equipment gear 3 to make both link, and the first driving gear 11 can depart from the first equipment gear 3 and engages to make both single actions, second driving gear 21 can be meshed with the second equipment gear 4 to make both link, second driving gear 21 can depart from the second equipment gear 4 and engages to make both single actions, thus make the first driving gear 11 and the second driving gear 21 realize single action in a certain state, link in a certain state, and then make the first driving shaft 1 and the second driving shaft 2 single action or interlock.
As shown in Figure 2, in embodiment provided by the invention, the axis of the first driving gear 11, first equipment gear 3, second equipment gear 4, second driving gear 21 is parallel mutually and be positioned at same plane; Certainly, in other embodiments, the position of the first driving gear 11, first equipment gear 3, second equipment gear 4, second driving gear 21 can adjust accordingly according to different demand.
In addition, first driving gear 11 has the first cam and stops arc 111, first equipment gear 3 has and to stop the first recessed only arc 31 of taking turns that arc 111 matches with the first cam and independently can turn an angle relative to the first equipment gear 3 to make the first driving gear 11, and make the first equipment gear 3 in this several angle of the independent rotation of the first driving gear 11 not by with then be remain static.First equipment gear 3 also has the second recessed wheel and stops arc 32, second equipment gear 4 has recessedly with second takes turns the second cam that only arc 32 matches and stops arc 41, to make the second equipment gear 4 independently can turn an angle relative to the first equipment gear 3, and make the first equipment gear 3 in independent this several angle rotated of the second equipment gear 4 not by with then be remain static.Second driving gear 21 have to stop with the second cam that arc 41 matches the 3rd recessedly take turns only arc 211, to make the second equipment gear 4 independently can turn an angle relative to the second driving gear 21, and make the second driving gear 21 in this several angle of the relatively independent rotation of the second equipment gear 4 not by with then be remain static.
Below list the rotation order of the first driving shaft 1 and the one of the second driving shaft 2 in rotation process " single action-interlock-single action ";
Concrete, the 360 degree of rotations of batch-type rotary axis mechanism energy, when angle between two hinge body of electronic equipment is for 0 shown in Fig. 6 degree, first driving shaft 1 and the state residing for the second driving shaft 2 are original state (state shown in Fig. 7), angle between two hinge body turns in the process of the first angle value (state shown in Fig. 9) by 0 degree, first cam of the first driving gear 11 stops arc 111 and matches with the first recessed only arc 31 of taking turns of the first equipment gear 3, first equipment gear 3 is meshed with the second equipment gear 4, second cam of the second equipment gear 4 stops arc 41 and matches with the 3rd recessed only arc 211 of taking turns of the second driving gear 21, first driving gear 11 can not drive the second driving gear 21 to rotate by when rotating in 0 degree to the first angular range, first driving gear 11 single action,
Angle between two hinge body is rotated further in the process of the second angle value (state shown in Figure 13) by the first angle value, and the first driving gear 11 is meshed with the first equipment gear 3; And driven together with the second driving gear 21 by the first equipment gear 3 and the second equipment gear 4 and rotate, thus realize the interlock of the first driving gear 11 and the second driving gear 21;
Angle between two hinge body is rotated further in the process of 360 degree by the second angle value, as shown in figure 15, first driving gear 11 is still meshed with the first equipment gear 3, second of first equipment gear 3 is recessedly taken turns only arc 32 and the second cam of the second equipment gear 4 to stop arc 41 relative, second equipment gear 4 is meshed with the second driving gear 21, second driving gear 21 can not drive the first driving gear 1 to rotate when angle is turned to rotated in the angular range of 360 degree by the second angle value, the second driving gear 21 single action.
Because the first driving gear 11 is fixed on the first driving shaft 1, second driving gear 21 is fixed on the second driving shaft 2, therefore, the first driving shaft 1 is identical with the rotation relation between the first driving gear 11 and the second driving gear 21 with the rotation relation of the second driving shaft 2.Certainly, the interlock in rotation process between the first driving shaft 1 from the second driving shaft 2 and single action order and angle can adjust accordingly according to different demand.
Structurally more optimize for making batch-type rotary axis mechanism of the present invention, as shown in Figure 2, axle center locating piece comprises the first location piece 51 and the second location piece 52, first driving shaft 1 and the second driving shaft 2 are all arranged on the first location piece 51 and the second location piece 52, and the first driving gear 11 and the second driving gear 21 are all between the first location piece 51 and the second location piece 52; First equipment gear 3 and the second equipment gear 4 are rotationally connected with between the first location piece 51 and the second location piece 52 respectively.Further, in order to improve the Security of each gear when engaging each other and working life, all adopting the intermittent gear of outer gearing formula cylinder in the present embodiment, and adding the transverse tooth thickness of each intermittent type gear.
In addition, in order to ensure the first driving shaft 1 and the second driving shaft 2 turn to arbitrarily angled after can keep its attitude, have employed in the present embodiment in two prongs 61 that one end that fork-shaped torque stand 6, first driving shaft 1 and the second driving shaft 2 do not connect hinge body is arranged in fork-shaped torque stand 6 respectively with provide in the rotation process of the first driving shaft 1 and the second driving shaft 2 one with the resistance of direction of rotation; Because resistance is by the first driving shaft 1 and frictional force when relatively rotating between the second driving shaft 2 and the prong 61 of fork-shaped torque stand 6, and the size of frictional force is determined by the friction factor of two rubbing surfaces and pressure, in order to regulate the size of resistance according to different demand, add adjusting bolt 732 in the present embodiment, change the first driving shaft 1 and the pressure size between the second driving shaft 2 and prong 61 by adjusting bolt 732.
