Connect first rotating shaft, described first rotating shaft is rotatably arranged on described pedestal, described first rotating shaft drive connection first nut;
Described push rod includes the first screw mandrel, and described first screw mandrel is connected with described first nut thread.
Described transmission component also includes the second rotating shaft, and described second axis of rotation is arranged on described pedestal, and described second
It is connected by the first synchronous belt transfer assembly between rotating shaft and described first rotating shaft, and, connect in described second rotating shaft
There is the second nut;
Described push rod also includes the second screw mandrel, and described second wire rod thread connects described second nut.
Described transmission component also includes the 3rd rotating shaft, and described 3rd axis of rotation is arranged on described pedestal, and the described 3rd
It is connected by the second synchronous belt drive assembly between rotating shaft and described second rotating shaft, described 3rd rotating shaft is connected with the 3rd
Nut;
Described push rod also includes the 3rd screw mandrel, and described 3rd wire rod thread connects described 3rd nut.
More multigroup rotating shaft, nut and screw mandrel can also be arranged as required to.
The other end of described push rod is connected on panel beating, side plate described in described panel beating drive connection.
Described pedestal is body structure, and described driving means and described transmission component are arranged in described pedestal.
It is additionally provided with the limit assembly for controlling described side plate displacement between described pedestal and described side plate.
Described limit assembly includes the limit switch for controlling described driving means being arranged on described pedestal, and sets
Put the position sensor for detecting corresponding side plate displacement on described side plate.
Compared with prior art, the seat of adjustable-width provided by the present invention, can be between the amount of automatically adjusting side plate
Relative distance, thus being adapted to the user of different building shape, obtains more preferable massage effect and more comfortable ride experience.
Structure provided by the present invention is particularly suitable for application to use on massage armchair.
Brief description

Specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, the seat of this adjustable-width includes:
Base 1, takes for user, is conventional structure.
Side plate 2, has two pieces, is separately positioned on the both sides of base 1, for installing other related components, and can be used as helping
Handss use.
Governor motion, has two sets, is separately positioned between base 1 and corresponding side plate 2, for change side plate and base 1 it
Between distance thus changing the relative distance between biside plate so that the user of different building shape take more comfortable.
Governor motion includes:Driving means 3, transmission component 4 and push rod.Wherein driving means 3 and transmission component 4 are arranged on
In the pedestal 11 of body structure, pedestal 11 is fixed on base 1.
Push rod is made up of three the first screw mandrels 51 be arrangeding in parallel, the second screw mandrel 52 and the 3rd screw mandrel 53;Three screw mandrels
Outer end is fixed on T-shaped panel beating 21, and T-shaped panel beating 21 is fixed on side plate 2.
Driving means 3 in the present embodiment are endless screw electric motor, install on the base 11.
Transmission component 4 includes the first helical gear 41 being meshed with endless screw electric motor, the first first turn of helical gear drive connection
Axle 42, first rotating shaft 42 is rotatably arranged on pedestal 11, first rotating shaft 42 drive connection the first nut 43;First nut 43 screw thread
It is connected on the first screw mandrel 51.
First rotating shaft 42 passes through the first synchronous belt transfer assembly 61 drive connection the second rotating shaft 44;Second rotating shaft 44 rotates
Setting on the base 11, and, is connected with the second nut 45 in the second rotating shaft 44;Threaded second nut of second screw mandrel 52
45.
The second synchronous belt drive assembly 62 drive connection the 3rd rotating shaft 46 is passed through in second rotating shaft 44, and the 3rd rotating shaft 46 rotates
Setting on the base 11, the 3rd rotating shaft 46 is connected with the 3rd nut 47;Threaded 3rd nut 47 of 3rd screw mandrel 53.
Limit assembly, including the limit switch 81 being correspondingly arranged on the base 11 and the position sensing being arranged on side plate 2
Device 82.
It is additionally provided with pedestal 11 and open for the belt pulley adjusting the belt tightness degree in the first synchronous belt drive assembly 61
Tight device 9.Pulley tensioner 9 can as needed select of the prior art any one.
The seat operation principle of this adjustable-width is described as follows:
When needing to adjust the distance between biside plate, start turbo-dynamo work, drive first rotating shaft to rotate, first turn
While axle rotates in the presence of first, second timing belt pulley, second, third rotating shaft synchronous axial system, three screw mandrels are each
The synchronizing moving under the driving of corresponding nut, drives T-shaped panel beating to drive side plate to move;Arrive when position sensor detects side plate
Reach setting gear when, limit switch close turbo-dynamo;The distance between biside plate is adjusted to the position of setting.
