Massage mechanism 2 as shown in Figure 6, motor D ₁Be installed on the chair back, drive small belt pulley 50, big belt pulley 58 rotations, big belt pulley is installed on the chair back with axle 59 and bearing 60, fix a cam 57 on the big belt pulley 58, make roller 53 and cover 56 reciprocating during its rotation, bearing pin 54 is fixed on the cover 56, ship and resell on another market and 55 pass plate 52 and plate is pressed on the bearing pin 54, so the contact on the plate carries out upper and lower motion and finishes massaging action.

Fig. 7, Fig. 8 show the structure of side shield, several long louvered boards 61 are put as taking mutually as the blind window, its end penetrates in the hole of support 62 and makes it can not deviate from the hole with fan-shaped part, but can be relative to rotating mutually, the support 62 at two ends needs in the relative both sides of louvered board 61, and this model 61 can be stacked fully mutually.

Fig. 9 is the structure chart of side door switching mechanism 7, motor D ₃Be installed in the supporting of being fixed in framework 22, and by 78 rotations of small belt pulley 63 drive big belt pulleys, leading screw 76 usefulness bearings 77 are contained on the support 28 and are affixed with big belt pulley, leading screw rotating band movable slider 71 moves along feed rod 65, and to make guide rod 67 be that rotate at the center with bearing pin 66, guide rod 67, side door 68 is all affixed with bearing pin 66, so when the slide block side-to-side movement, side door is opened or closed, and bar 69 1 ends are fixed on the seat 84, and the other end and pressure pin 73 are hinged, axle 74 on the other end of pressure pin is held closet 75, bar 70 1 ends and side door are fixed, and an end of the other end and bar 72 is hinged, and the other end of bar 72 is articulated in the appropriate location of bar 73, when side door is opened, bar 70 motions, and bar 72 is put the closet pull-up to the position in side door hole, as shown in figure 10.Figure 10 king-rod 69 all is the upright position basically with bar 73.

Figure 11, the 12nd, the chair back play Electrical Discharge Machine D ₂The energy-conservation mechanism of starting, belt pulley 79 skies be enclosed within on the motor shaft, one side of belt pulley has two centrosymmetric relatively boss 82, cover 83 is fixed with motor shaft, also has one 80 on the external diameter of the end face that contacts with belt pulley of cover, and the distance of boss 82 and 80 pairs of motor center of boss equates.The outer spring 81 in addition of cover, it is rolled by spring steel wire and about 4.5 circles of curl, its internal diameter needs greater than the external diameter of cover and is enclosed within outside the cover, two ends are stretched out and are made a straightway, and this two straightway is abutted against mutually with boss 82 respectively, fix at the mid point of spring steel wire and cover 83, like this, make between two boss 80, to make starting that the idle running of quarter turn be arranged, reach the purpose that reduces starting current in the position of electric motor starting front boss 80.

Figure 13 is the electric control schematic diagram, wherein K ₁Be light switch, K ₂Be side door switch, K ₃Be that the chair back keeps flat, K ₄Be that the corner back of the body is holded up K ₃, K ₄Be to connect pin, K ₅Be the massage switch, K ₆～K ₉Be limit switch, side door opens and closes and the chair back rises and puts totally 4, as 64 among Fig. 9, is placed on the two ends of the stroke of slide block 71, makes it outage in time and stops the running of side door switching.

So multifunction nursing chair of the present utility model can be transformed into bed, the chair back also can stop at any suitable angle, to satisfy patient's requirement, can finish massage work, carry out the nursery work of defecation, food boxes can also be arranged, get food easily, towel bracket can be taken and put towel, and clipboard can be write and be read, also can hang mosquito net, becomes a kind of multi-functional nursing chair, certainly, these functions can be selected.
