Description
Technical field
This programme is related to a kind of chair more particularly to a kind of multifunctional chair and gear switching device.
Background technique
There are many kinds of standing chairs in the prior art, such as a kind of lower limb rehabilitation training based on more position electric wheel-chair vehicles
System has a wheelchair frame, is installed with standing mechanism, the mechanism that lies low, lower limb training mechanism, wheelchair frame above wheelchair frame
Install traveling mechanism below, standing mechanism and lower limb training mechanism respectively with wheelchair frame rotation connection, the mechanism that lies low and stand
It is rotatablely connected between mechanism, stands, lies low for patient's realization, the active training under sitting posture, passive exercise, weight-losing peace
Weighing apparatus is trained, and wheel-chair control and virtual reality training mechanism, wheel-chair control and virtual reality instruction are also installed above wheelchair frame
Practice mechanism and control connection standing mechanism, the mechanism that lies low, lower limb training mechanism, traveling mechanism respectively, realizes traveling and based on virtual
The sitting posture of reality, the multi-pose leg training stood, lain low.The disadvantages of this solution is that multiple motors is needed to respectively drive standing machine
Structure, the mechanism that lies low, lower limb training mechanism, traveling mechanism, it is unrelated to cause structure multiple due to each inter-agency independent arrangement
Miscellaneous, equipment is heavy, high failure rate, is unsuitable for energy conservation and light-weighted requirement.
Utility model content
In view of the shortcomings of the prior art, proposing a kind of multifunctional chair, it has is pushed away this programme by gear switching device change
The thrust point of bar motor makes chair realize that standing, lift leg, lie down three kinds the characteristics of converting posture.
The technical measures that this programme is taken are: a kind of multifunctional chair, it includes seat base and is set to seat base
On leg grillage backboard is fixedly installed on four-bar mechanism it is characterized in that being provided with four-bar mechanism in seat base
And seat plate, four-bar mechanism and leg grillage is coaxial is hinged in seat base, push-rod electric machine is fixed between seat plate and leg grillage,
It is fixedly installed between relevant switching device realization four-bar mechanism and seat base and leg grillage and selects in four-bar mechanism lower end
Selecting property ground associated connection.
It is driven by push-rod electric machine, rises four-bar mechanism backboard, seat plate inclination, chair is made to become standing from standing and sitting gesture
Standing position state；And the locking that can be changed between four-bar mechanism and seat base and leg grillage by association switching device closes
In the case that system, makes the thrust point of push-rod electric machine change, and push-rod electric machine drives the principle of four-bar mechanism constant,
Realize that leg plate when sitting posture lifts and put down function respectively, i.e. lift leg posture；Leg plate when lying low lifts, backboard hypsokinesis, that is, lies
Prone position state.Leg plate is motionless when standing, and backboard rises and seat plate slopes up to uprightly, i.e. midstance.
The specific feature of this programme in addition, four-bar mechanism by stull, double leval jib lower brace, double leval jib back on double leval jib
Vertical pole, double leval jib leg vertical pole composition；One end of stull is hinged on the top of double leval jib leg vertical pole and double leval jib；Double leval jib back
The other end of stull is hinged on the lower part of portion's vertical pole and double leval jib；Under one end of double leval jib lower brace and double leval jib back vertical pole
End is hinged；The other end of double leval jib lower brace and double leval jib leg vertical pole top are hinged.Four-bar mechanism includes being set to seat
Two groups of two sides of base portion and the consistent left and right of structure.
Stull is end on double leval jib is the U-lag that Open Side Down, is provided with and forward extends out in the upper end of seat base
Vertical pole connector, double leval jib leg vertical pole, vertical pole connector and leg grillage are sequentially coaxially fixed on the U of stull front end on double leval jib
In shape slot.
Being associated with switching device includes the gear cross bar hinged with double leval jib leg vertical pole, is fixedly installed in gear crossbar end
There is gear switch handle, fix on gear cross bar there are two link after preceding link and two, preceding link and rear link are located at shelves
Position cross bar front and rear sides are symmetrical；It is fixedly installed on leg grillage and is only linked up with the preceding monolock of two preceding link cooperations,
