Specific embodiment
The present invention is described in further detail below in conjunction with attached drawing embodiment.
As shown in Fig. 1~Figure 12, the transmission mechanism of the door device in the present embodiment, for connecting door body to drive door body
Carry out opening and closing movement.The transmission mechanism of the door device includes pedestal 1, linear motor stator electric 2, the first lead 3, two second
Lead 7, linear motor guide rail 5, sliding block 4, plate body 6.
Pedestal 1 in the present embodiment is the frame-shaped pedestal 1 with top plate, front side board, back side panel, left plate and right plate.
Linear motor stator electric 2 is then horizontally arranged at the top position of 1 back side panel of pedestal in left-right direction.
The left and right ends of pedestal 1 are connected separately with the second lead 7, second lead 7 be fixedly connected on front side board and
Between back side panel, be slidably connected a link block 8 on each second lead 7, which can be relative to the second lead 7
It is moved forward and backward, the both ends of the first lead 3 are then separately fixed on the link block 8, so that the first lead 3 can
Back-and-forth motion is done relative to pedestal 1.In use, door body can be slidably connected at by taking door frame on first lead 3,
First lead 3 is used as the load-bearing part of door body.
Sliding block 4 includes matrix 41, linear motor coil 42, slide 43, guide pad 44, third lead 46 and directive wheel
45.Wherein linear motor coil 42 is fixedly connected on matrix 41, which is located at the top position in 41 rear portion of matrix
It puts and is extend into linear motor stator electric 2 with that can coordinate, thus with 2 cooperating of linear motor stator electric.Straight line in the present embodiment
Motor stator 2 and linear motor coil 42 collectively form a linear motor, operation principle compared with linear motor work
Principle.Linear motor coil 42 generates transverse-electromagnetic thrust after being powered between linear motor stator electric 2, so as to push linear motor
Coil 42 is moved left and right relative to linear motor stator electric 2, and then is moved left and right with 4 entirety of movable slider.
Linear motor guide rail 5 is connected to the top position of front side wall of pedestal 1, and slide 43 is then connected to the forepart of matrix 41
Top position, and slide 43 can be embedded in linear motor guide rail 5, and so during slip moves left and right, this is straight
Line motor slide rails 5 with the movement for being combined into sliding block 4 with slide 43 then by providing guiding, also as linear motor coil 42
Movement provides guiding.
Third lead 46 is fixedly connected on the lower section of the matrix 41 of sliding block 4 and sets along the longitudinal direction, guide pad 44
It is then slidably socketed on the third lead 46, while there are one the logical pilot holes set in left-right direction for tool on the guide pad 44
441, which is also slidably socketed on the first lead 3 by the pilot hole 441 with relative to the first lead 3 or so
It is mobile, and then the door body being connected on the first lead 3 is pushed to carry out side-to-side movement, to realize the opening and closing movement of door body.
Directive wheel 45 is fixedly connected on the lower section of guide pad 44.Plate body 6 is connected to the position of the back side panel of pedestal 1 on the lower.
The raceway 61 of 45 movement locus of restricted guidance wheel is provided on the upper surface of plate body 6, which is embedded in the raceway 61
And it can roll and move relative to the raceway 61.
Different according to the door body that the transmission mechanism of the door device is applied, the track of raceway 61 can be set can also be corresponding
Change.Such as when using in the translating door system for only needing door body one direction opening and closing left and right, which can lead with first
It is arranged in parallel to column 3, i.e., is through to the other end from one end of plate body 6.
When using in sliding plug door system, then raceway 61 is set as：From one end of plate body 6 edge and the first lead 3
Parallel direction extends and is bent backward in the other end of plate body 6, i.e., forms a recurvate arc in the other end of plate body 6
Track.The transmission mechanism of door device in the present embodiment then uses the program.
It can directly use, be applied in double-door system when the transmission mechanism use of the door device is in single opening door system
The length of the transmission mechanism that two groups of door devices can be symmetrical arranged when middle or the transmission mechanism for lengthening door device, together
When sliding block 4 and plate body 6 be set as symmetrical two groups.
As is illustrated by figs. 11 and 12, the transmission mechanism of the door device applies the course of work in sliding plug door system such as
Under：
When carry out stopping sliding door closing motion when, linear motor coil 42 is powered, so with movable slider 4 slide 43 limit
The lower phase stopping sliding door closing direction linear movement of system, correspondingly, the guide pad 44 on sliding block 4 pushes what is connected on the first lead 3
Stopping sliding door door body moves along a straight line to carry out closing motion to closing direction.At this point, directive wheel 45 is also in the raceway 61 of plate body 6
Straight line portion moves.
It, then can be in raceway when directive wheel 45 moves to the arch section of raceway 61 with the continuous movement of directive wheel 45
It is moved backward under 61 restriction effect, and then directive wheel 45 can drive guide pad 44 relative to matrix 41 on third lead 46
It slides backward.Guide pad 44 can pull the first lead 3 to be moved backward on the second lead 7 relative to pedestal 1 simultaneously,
Under the drive of one lead 3, the door body of stopping sliding door also can backward be moved relative to pedestal 1, so as to which the closure for completing stopping sliding door is moved
Make.
When the opening action for carrying out stopping sliding door, then entire action process is opposite with the above process.
