The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1; The utility model electric open-door mechanism comprises linkage 100, drive unit 200 and goes up door-plate 400, following door-plate 500; Drive unit 200 is fixed in the lampblack absorber body 2 through connecting plate 600, and drive unit 200 drive link mechanisms 100 make linkage 100 motions.Linkage 100 comprises connecting rod 110 and lower link 120, and last connecting rod 110 comprises driving lever 111 and go up follower lever 112 that lower link 120 includes down driving lever 121 and reaches follower lever 122 down.The output shaft 201 of the head end of last driving lever 111 and drive unit 200 is fixing, and the head end of tail end and last follower lever 112 articulates, and the tail end of last follower lever 112 is connected with last door-plate 400; The output shaft 201 of the head end of following driving lever 121 and drive unit 200 is fixing, and tail end articulates with the head end of following follower lever 122, and the tail end of following follower lever 122 is connected with following door-plate 500.
With reference to Fig. 1 and Fig. 2, the motion process of above-mentioned electric open-door mechanism is following:
(1) the last driving lever 111 of last connecting rod 110 is pressed the orbiting motion of the first circular arc A under the driving of the output shaft 201 of drive unit 200.The bottom of the tail end of last follower lever 112 and last door-plate 400 articulates, and top edge of door-plate 400 and lampblack absorber body 2 articulate on this.When 400 motions of last door-plate, be the center of circle with its pivoting point 401 with lampblack absorber body 2, under the effect of last follower lever 112, press the orbiting motion of the second circular arc B.
(2) simultaneously, the following driving lever 121 of lower link 120 is pressed the orbiting motion of three-arc C under the driving of the output shaft 201 of drive unit 200.The tail end of following follower lever 122 articulates with the top of following door-plate 500, and the lower limb of following door-plate 500 and lampblack absorber body 2 articulate.During door-plate 500 motion instantly, be the center of circle, under the effect of follower lever 122 down, press the orbiting motion of the 4th circular arc D with its pivoting point 501 with lampblack absorber body 2.
When drive unit 200 work and drive go up driving lever 111 and down driving lever 121 when the direction of arrow is rotated; Last driving lever 111 and down driving lever 121 be the center through output shaft 201, drive respectively and go up follower lever 112 and the orbiting motion of the follower lever 122 edge first circular arc A and three-arc C down; Last door-plate 400 is the orbiting motion that the center of circle produces the second circular arc B with the pivoting point 401 of itself and lampblack absorber body 2 under the drive of last follower lever 112; Following door-plate 500 is the orbiting motion that the center of circle produces the 4th circular arc D with the pivoting point 501 of itself and lampblack absorber body 2 under the drive of following follower lever 122.Thereby can drive door-plate 400, play door-plate 500 to go up and down simultaneously.By on can know that the utility model electric open-door mechanism range of operation is less, can seal better.
With reference to Fig. 3; Last door-plate 400 and lampblack absorber body 2 pivoting points 401 and down the pivot joint method of door-plate 500 and lampblack absorber body 2 pivoting points 501 be that axle articulates with draw-in groove, the example that is connected to of above door-plate 400 and lampblack absorber body 2, last door-plate 400 is provided with a 401a; Lampblack absorber body 2 is provided with draw-in groove 401b; Certainly, also can on the lampblack absorber body 2 axle be set on the plate 400 draw-in groove being set to the doorstep.The internal diameter of this draw-in groove 401b is adaptive with the external diameter of axle 401a, so that go up the dismounting of door-plate 400 and following door-plate 500; And the width at the edge of draw-in groove 401b is slightly littler than the external diameter of axle 401a, makes an axle 401a can be stuck in the draw-in groove 401b and difficult drop-off.In one embodiment, this draw-in groove 401b can be Ω shape or other shape.
Above-mentioned electric open-door mechanism also can be provided with pad, and this pad can be at least a with in the lower gasket: metal sliding shim, oil-containing pad or plastic cement pad, and be positioned at and respectively articulate the position, for example go up the pivot joint position of driving lever 111 and last follower lever 112 etc.Above-mentioned pad has self-lubricating property, with the friction process of other parts in, can separate out lubricator, for example graphite, lubricating oil or plastic cement particle etc.
Above-mentioned drive unit 200 is a reducing motor, is provided with motor and the deceleration device that links to each other with motor output shaft 201.This deceleration device is a reduction gear box, is provided with train of reduction gears in it.This output shaft 201 is stretched out by the two ends of reduction gear box, and it is fixedly connected with last driving lever 111 and following driving lever 121 respectively.Reduction gear box is through output shaft 201 power outputs, and output shaft 201 can drive driving lever 111 and descend driving lever 121 to rotate together when motor is worked.The selection mode of motor has multiple, can select dissimilar motors according to different application scenarios, for example, and synchronous motor, stepper motor etc.
The utility model has reduced the range of movement of electric open-door mechanism through drive unit 200 being fixed in lampblack absorber 2 body interior, has practiced thrift material, has reduced manufacturing cost; Make lampblack absorber body 2 can isolate better or the sealing electric door-opening mechanism.
