Embodiment
Embodiment one：
The present invention provides a kind of chair, as shown in figure 1, including cushion 1, backrest 2, handrail 3, support 4 and roller 5, cushion 1
It is located on support 4, backrest 2 is connected to the rear side of cushion 1, the top of backrest 2 is located at the left and right of cushion 1 provided with headrest 21, handrail 3
Both sides, roller 5 is arranged on the bottom of support 4, and support 4, which is provided with, is used for the electromagnetic brake that roller 5 brakes, and support 4 is provided with interior
Power supply 9, brake switch circuit and brake control circuit are put, built-in power 9 is electrically connected by brake switch circuit and electromagnetic brake
Connect, brake control circuit includes control chip 8, the capacitance touch key 6 being located on handrail 3, first pressure sensor 71, is located at
Second pressure sensor 72 and the 3rd pressure sensor 73 that is located on cushion 1 on headrest 21, built-in power 9 are control core
Piece 8 is powered, and control chip 8 is electrically connected with brake switch circuit, capacitance touch key 6, first pressure sensor 71, second pressure
The pressure sensor 73 of sensor 72 and the 3rd is electrically connected with control chip 8 respectively, and control chip 8 passes through capacitance touch key 6
Whether electric capacity changes and whether first pressure sensor 71, the pressure sensor 73 of second pressure sensor 72 and the 3rd detect pressure
Power controls whether electromagnetic brake works.
User is detected using three pressure sensors using the pressure for producing chair different parts during chair to judge
The action of user is intended to, can realize in theory 2 × 2 × 2 amount to that 8 kinds of actions are intended to be handled differently, user can be used
Action during chair is intended to be finely divided, and to control the brake Background control of roller 5, then coordinates the touch action of user to make electric capacity
The capacitance variations of formula membrane keyboard 6 realize the subjective brake control of user, simultaneously because controlling electromagnetic system using built-in power
Dynamic device, therefore electromagnetic brake response is timely, be swift in motion, and greatly improves the comfortableness that user uses chair, more hommization.
Built-in power can use battery, and such as lithium battery etc. is provided with for filling that built-in power charges on support 4
Electrical interface 91, it would however also be possible to employ wireless charging mode is charged.Built-in power can also use dry cell.Brake switch circuit
It can be realized using electronic switches such as triode, FET or controllable silicons.Control chip 8 is according to capacitance touch key 6
Capacitance variations and first pressure sensor 71, the low and high level signal of the pressure sensor 73 of second pressure sensor 72 and the 3rd come
Judge the action of user, determine whether to send switching signal to make brake switch circuit turn-on.General, capacitance touch
The capacitance variations of key 6 then send high level signal, first pressure sensor 71, the and of second pressure sensor 72 to control chip 8
3rd pressure sensor 73 detects and also sends high level signal to control chip 8 respectively after pressure, is otherwise low level signal.
And specific to control chip 8 control electromagnetic brake whether work can according to user using action during chair come
It is determined that, the mode of operation that whether default control electromagnetic brake works in control chip 8 is as follows：
First, user typically directly grips on backrest 2, is not sitting on chair, therefore, now when standing promotion chair
First pressure sensor 71 is not detected by pressure and second pressure sensor 72 is not detected by pressure, the control brake of control chip 8
On-off circuit disconnects electromagnetic brake, is easy to user to promote chair, and chair is in non-braking state, need not now judge electricity
Whether the electric capacity of appearance formula membrane keyboard 6 changes, whether the 3rd pressure sensor 73 detects pressure.
2nd, when user is wanted into seat, handrail 3 typically all can be with the hands buttressed, now first pressure sensor 71 is detected
Pressure, second pressure sensor 72 are not detected by pressure and the 3rd pressure sensor 73 is not detected by pressure, and control chip 8 is controlled
Brake switch circuit turns on electromagnetic brake, and chair is in braking state, it is to avoid user enters leg when sitting and encounter chair to cause chair
Son, which is slipped out of the hand, runs away and sits sky.
3rd, user normally falls after seat, and in seat state is normally fallen, second pressure sensor 72 will detect pressure, this
As long as when capacitance touch key 6 electric capacity is unchanged, the 3rd pressure sensor 73 is not detected by pressure, just explanation user normally makes
Normal office work is sat in chair, both hands avoid chair from being run away when user adjusts normal sitting position all on the table, now, control
The control brake switch circuit of chip 8 turns on electromagnetic brake, and chair is in braking state.
4th, user be sitting in chair want shift position when, typically can all hold handrail 3, therefore pass through capacitance touch key 6
Electric capacity is detected to change, at the same first pressure sensor 71 detect pressure, second pressure sensor 72 detect pressure and
3rd pressure sensor 73 is not detected by pressure, and the control brake switch circuit of control chip 8 disconnects electromagnetic brake, at chair
In non-braking state, user is facilitated to be sitting in shift position on chair.Due to requiring that user holds handrail 3, while body can not be in
Body relaxation state, can just be seated mobile chair, therefore can cultivate the good habit that user security uses chair.
5th, user wants to loosen and had a rest, naturally will using headrest 21, while both feet landing chair can be produced to
Thrust afterwards, now second pressure sensor 72 detects pressure and the 3rd pressure sensor 73 detects pressure, without
Whether the electric capacity for judging capacitance touch key 6 is changed, whether first pressure sensor 71 detects pressure, and control chip 8 is controlled
Brake switch circuit processed turns on electromagnetic brake, and chair is in braking state, it is to avoid chair moving influence user rests.
In addition to above-mentioned five kinds of patterns, user, can be basic herein using other actions also occur during chair
It is upper rationally to be expanded.In order to avoid user misoperation, capacitance touch key 6 is arranged on the lower surface of handrail, and leans on relatively
Before.
In the present embodiment, electromagnetic brake is electromagnetic power brake, as shown in Fig. 2 electromagnetic power brake includes
Housing 101, housing 101 is connected with support 4, is provided with magnetic chamber 102 in housing 101, and the periphery of magnetic chamber 102 is around being equipped with excitation coil
103, excitation coil 103 is electrically connected with brake switch circuit, and roller 5 includes 101 turns of wheel shaft 51 and wheel body 52, wheel shaft 51 and housing
