Stablize, gear wheel 8 is connected by terminal pad 9 with wheelchair upper frame, and user is sitting on wheelchair, and gear wheel 8, which goes out, to be born to come from
The larger pressure on wheelchair top reuses bearing bracket stand 37 outside two bearings and is reinforced, avoid gear wheel 8 during rotation because
Stress is excessive and shifts, and guarantees stability of the wheelchair in rotary course.
In use, user controls first motor 12 by control button when wheelchair is when needing and bed body is to access digit
It starts turning, first motor 12 drives pinion gear 11 to rotate, and pinion gear 11 drives gear wheel 8 to rotate, gear wheel 8 and upper frame segment
Frame is held together by terminal pad 9 through being bolted, and the rotation of gear wheel 8 drives entire frame rotation, when rotation position makes
When nylon switch block 27 and short swing rod belt wheel microswitch 26 are collided, the rotation of first motor 12 stops, at this time the gear wheel 8 of wheelchair and
Upper frame just has rotated 90 °, and frame position is parallel with fixed bed body portion, it can be achieved that docking on wheelchair at this time.
After rotation terminates, the second motor 22 starts to rotate, and by positive coupling 28, shaft 23 is driven to rotate, turned
Axis 23 drives the eccentric wheel 19 in loose slot 18 to rotate, and the rotation of eccentric wheel 19 drives movable block 15 to slidably reciprocate, when upper frame
After being rotated by 90 °, the second motor 22 is rotated by eccentric wheel 19, and distal end of the eccentric wheel 19 apart from shaft 23 follows rotation gradually to big
8 direction of gear is close, and movable block 15 slides under the elastic force effect of compressed spring 17 to 8 direction of gear wheel, when eccentric wheel 19
Distal end turn to gear wheel 8 apart from it is nearest when, the travel switch block 24 that shaft 23 drives also touches microswitch 25, second
Motor 22 stops operating, and the convex block 16 of 15 end of movable block also just reaches in the tooth socket of gear wheel 8, and gear wheel 8 is blocked, living
Motion block 15 remains stress under the elastic force effect of compressed spring 17, and the convex block 16 of end can be pushed against canine tooth always
In the tooth socket of wheel 8, it will not arbitrarily generate and move forward and backward, the rotation of gear wheel 8 is locked, prevent the top of gear wheel 8 and wheelchair
Frame rotates, and realizes the function of the rotational positioning of wheelchair；
When frame needs to rotate again, the second motor 22 is continued to rotate, by 19 Compressive activities block 15 of eccentric wheel in work
It is slided in dynamic slot 18 far from gear wheel 8, squeezes compressed spring 17, the convex block 16 of 15 end of movable block is from the tooth socket of gear wheel 8
It is detached from, first motor 12 continues to rotate, and gear wheel 8 is driven to rotate, and the rotation of wheelchair upper frame is realized, when eccentric wheel 19 rotates
Travel switch block 24 is driven to continue to rotate to the microswitch 25 of the other side by shaft 23, the second motor 22 stops turning
Dynamic, after gear wheel 8 is rotated by 90 °, the nylon switch block 27 of bottom touches another short swing rod belt wheel microswitch 26 again
Afterwards, first motor 12 stops operating, and the rotation of the second motor 22 repeats above-mentioned movement again, is clamped the convex block 16 of movable block 15
Into the tooth socket of gear wheel 8, locked positioning is carried out to gear wheel 8, realizes the automatic rotational positioning of wheelchair, user moves in bed
Leave body when, the traveling wheel of wheelchair will not rotate, guarantee wheelchair and bed body stability and safety, be conducive to product
Popularization and use.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
It protects in range.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
