A kind of seat of adjustable-width
Technical field
The present invention relates to seats, refer specifically to a kind of seat of adjustable-width.
Background technique
Massage armchair can simulate manpower and massage region, alleviate the fatigue of people.Massage armchair generally includes
The two sides of pedestal, pedestal are equipped with handrail.Width between existing two handrail of massage armchair be it is fixed, be not adjustable;To figure
Different people's massage effects is different, and to thinner user, the width of pedestal is wide between both side plate, and massage effect is poor;And it is right
It is obvious that sense is squeezed when more fat user, seating, or even can not be sat into.
Similarly there is the above problem in some individual seats.
Summary of the invention
The technical problem to be solved by the present invention is to the statuses for the prior art to provide a kind of seat of adjustable-width, with
The crowd for being adapted to different building shape uses, to guarantee the comfort taken.
The technical scheme of the invention to solve the technical problem is: the seat of the adjustable-width, including pedestal and
The side plate of pedestal two sides is set;It is characterized in that being equipped between the pedestal and the side plate can change between both side plate relatively
The regulating mechanism of distance.
The regulating mechanism includes the driving device of setting on the base, and the driving device connects on the base,
The driving device connects one end of push rod by transmission component, and the other end of the push rod connects the side plate.
It is preferred that the driving device is endless screw electric motor;
The transmission component includes the first helical gear being meshed with the endless screw electric motor, and the first helical teeth wheel drive connects
First rotating shaft is connect, the first rotating shaft is rotatably arranged on the pedestal, and the first rotating shaft is drivingly connected the first nut;
The push rod includes the first screw rod, and first screw rod is connect with first nut thread.
The transmission component further includes the second shaft, and second shaft is rotatably arranged on the pedestal, and described second
It is connected between shaft and the first rotating shaft by the first synchronous belt drive component, also, is connected in second shaft
There is the second nut;
The push rod further includes the second screw rod, and second wire rod thread connects second nut.
The transmission component further includes third shaft, and the third shaft is rotatably arranged on the pedestal, the third
It is connected between shaft and second shaft by the second synchronous belt drive component, is connected with third in the third shaft
Nut;
The push rod further includes third screw rod, and the third wire rod thread connects the third nut.
More multiple groups shaft, nut and screw rod can also be set as needed.
The other end of the push rod is connected on metal plate, and the metal plate is drivingly connected the side plate.
The pedestal is body structure, and the driving device and the transmission component are arranged in the pedestal.
The limit assembly for controlling the side plate displacement is additionally provided between the pedestal and the side plate.
The limit assembly includes being arranged on the pedestal to be used to control the limit switch of the driving device, and set
Set the position sensor being displaced for detecting corresponding side plate on the side plate.
Compared with prior art, the seat of adjustable-width provided by the present invention, can be between the amount of automatic adjustment side plate
Relative distance obtains better massage effect and more comfortable ride experience to be adapted to the user of different building shape.
Structure provided by the present invention is particularly suitable for application to use on massage armchair.
Detailed description of the invention
Fig. 1 is assembling structure of embodiment of the present invention stereoscopic schematic diagram;
Fig. 2 is the stereoscopic schematic diagram of driving device and transmission component assembling structure in the embodiment of the present invention;

Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown in Figure 1 to Figure 3, the seat of the adjustable-width includes:
Pedestal 1 is taken for user, is conventional structure.
Side plate 2 has two pieces, is separately positioned on the two sides of pedestal 1, for installing other related components, and can be used as and helps
Hand uses.
Regulating mechanism has two sets, is separately positioned between pedestal 1 and corresponding side plate 2, for changing side plate and pedestal 1 it
Between distance to change relative distance between both side plate so that the user of different building shape take it is more comfortable.
Regulating mechanism includes: driving device 3, transmission component 4 and push rod.Wherein driving device 3 and the setting of transmission component 4 exist
In the pedestal 11 of body structure, pedestal 11 is fixed on pedestal 1.
Push rod is made of three first screw rod 51, the second screw rod 52 and third screw rods 53 disposed in parallel;Three screw rods
Outer end is fixed on T shape metal plate 21, and T shape metal plate 21 is fixed on side plate 2.
Driving device 3 in the present embodiment is endless screw electric motor, and installation is on the base 11.
Transmission component 4 includes the first helical gear 41 being meshed with endless screw electric motor, and the first helical gear is drivingly connected first turn
Axis 42, first rotating shaft 42 are rotatably arranged on pedestal 11, and first rotating shaft 42 is drivingly connected the first nut 43;First nut, 43 screw thread
It is connected on the first screw rod 51.
First rotating shaft 42 is drivingly connected the second shaft 44 by the first synchronous belt drive component 61;The rotation of second shaft 44
Setting on the base 11, also, is connected with the second nut 45 in the second shaft 44;Second screw rod 52 is threadedly coupled the second nut
45。
Second shaft 44 is drivingly connected third shaft 46 by the second synchronous belt drive component 62, and third shaft 46 rotates
Setting on the base 11, is connected with third nut 47 in third shaft 46;Third screw rod 53 is threadedly coupled third nut 47.
Limit assembly, including the position sensing for being correspondingly arranged limit switch 81 on the base 11 and being arranged on side plate 2
Device 82.
The belt pulley for adjusting the belt tightness degree in the first synchronous belt drive component 61 is additionally provided on pedestal 11
Tight device 9.Pulley tensioner 9 can select as needed it is in the prior art any one.
The seat working principle of the adjustable-width is described as follows:
When needing to adjust the distance between both side plate, starting turbo-dynamo work, driving first rotating shaft rotation, first turn
While axis rotates under the action of the first, second timing belt pulley, second, third shaft is rotated synchronously, and three screw rods are each
From synchronizing moving under the driving of corresponding nut, T shape metal plate is driven to drive side plate mobile;When position sensor detects that side plate arrives
Up to setting gear when, limit switch close turbo-dynamo;The distance between both side plate is adjusted to the position of setting.
