The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Embodiment 1,
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of electric door anti-jamming device is provided with torsion clutch between the headstock gear 8 of the dynamical system 1 of said electric door and said electric door.
Said torsion clutch comprises power input shaft 2, power output shaft 7, moment of torsion output slide block 6, spring 4, connects ball 5 and supporting seat 3;
Said power input shaft 2 one ends and said dynamical system 1 are in transmission connection;
Said power input shaft 2 is arranged with said supporting seat 3, spring 4, moment of torsion output slide block 6 and power output shaft 7 successively from said dynamical system 1 one side direction opposite sides; Said supporting seat 3 is fixedly connected on the said power input shaft 2, and said moment of torsion output slide block 6 is located on the said power input shaft 2 with power output shaft 7 slip caps;
Said moment of torsion output slide block 6 and said power input shaft 2 are provided with the helical groove of mutual coupling, are embedded with said connection ball 5 in the said helical groove;
Said moment of torsion output slide block 6 is equipped with projection 9 with the one side that power output shaft 7 is in contact with one another;
An end and the said headstock gear 8 away from said moment of torsion output slide block 6 of said power output shaft 7 are in transmission connection.
During inactive state; Moment of torsion output slide block 6 is under the effect of spring 4; Be on the moment of torsion output station, at this moment, connect steel ball 5 and be in bolt indentation near supporting seat 3 one sides; The projection 9 of moment of torsion output slide block 6 and power output shaft 7 intersects nested, and moment of torsion output this moment slide block 6 and power output shaft 7 are owing to the existence of projection 9 can be rotated together.
Operating principle is that when switch was closed in the electric door startup, dynamical system 1 drove power input shaft 2 and rotates, owing to connect the effect of steel ball 5 and spring 4; Moment of torsion output slide block 6 is followed rotation, and under the effect of projection 9, power output shaft 7 rotates and drive headstock gear 8 runnings, and electric door is closed; Finish up to closing closed procedure, if in closing closed procedure, meet with obstruction, reverse power output shaft 7 and the moment of torsion output slide block 6 of passing to of the resistance that electric door runs into is when resistance is enough big; Overcome the pressure of spring 4, force moment of torsion output slide block 6 and power output shaft 2 that relative motion takes place, under the effect that connects steel ball 5 and helical groove; Moment of torsion output slide block 6 connects steel ball 5 and finally is in helical groove near power output shaft 7 one sides, at this moment to supporting seat 3 one side shiftings; The projection 9 of moment of torsion output slide block 6 and power output shaft 7 breaks away from each other, the action of electric door phase down, and dynamical system 1 drive moment of torsion output slide block 6 is rotated further; When projection 9 turns to nested position, under the effect of spring 4, moment of torsion output slide block 6 is retracted original position; If this moment, obstacle was removed, then electric door continues to accomplish closing motion, if obstacle is not removed; Then the projection 9 of moment of torsion output slide block 6 and power output shaft 7 breaks away under the effect of resistance each other, goes round and begins again, and disappears up to resistance.
Embodiment 2,
All the other are identical with embodiment 1, and difference is that the contact surface between the said at closing time projection 9 of said electric door is processed with circular arc chamfering.Disengaging and the contract that can be beneficial between the projection 9 of moment of torsion output slide block 6 and power output shaft 7 are gone into, and reduce to impact and wear and tear.Be connected through bearing between said power output shaft 7 and the said power input shaft 2.The power of can reducing friction and wearing and tearing also can be fixed their mutual alignment.
All the other are identical with embodiment 1, and difference is that said electric door anti-jamming device also is provided with in order to detect the sensor of moment of torsion, moment of torsion output slide block 6 corners or moment of torsion output slide block 6 positions, and said sensor is electrically connected with said dynamical system.When meeting with obstruction, sensor detects correlated variables, and 1 counter-rotating of control dynamical system is opened electric door, is beneficial to remove obstruction.
Adopt the beneficial effect of present technique scheme to be: to be provided with torsion clutch between the dynamical system that is employed in said electric door and the headstock gear of said electric door, to make electric door when closing hindered lift-cabin door, the moment of torsion increase on the power transmission shaft; Torsion clutch is threaded off, and electric door is kept harmless chucking power, and motor can not burn by stall; Cooperate this moment the counter-rotating of control circuit control motor to open the door, this device is the mechanical type anti-jamming device, and is simple in structure; Cost is low, fault rate and safe and reliable.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
