Description
Technical field
This utility model relates to the electric care bed of service robot technical field, specifically, is a kind of electric care bed armrest system that the automatic lifting function is arranged that is used for.
Background technology
Electric care bed be a kind of self-care ability that can improve bed old man or patient, alleviate nursing staff's working strength, reduce the service robot of kinsfolk's trouble and worry.Nursing bed generally all is provided with handrail, and it plays the certain protection effect to the old man or the patient of bed.At present the handrail of nursing bed has mechanical buckle-type, mechanical hand type, the lifting of nursing bed handrail all needs the nursing staff to carry out usually, and its shortcoming is, do not have auto-lock function, and user oneself can not be controlled automatically.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, be a kind of armrest system that can electronic control lifting of electric care bed configuration, even the nursing staff does not exist, patient also can be from the lifting of line operate handrail, make electric care bed use more convenient, hommization more.
For achieving the above object, the technical scheme taked of this utility model is:
A kind of electric care bed automatic armrest system, contain side plate handrail, support, upper and lower strut, it is characterized in that, armrest system is made of end support, connecting rod on side plate handrail, the inner big support of side plate, last end link, lower link, the side plate, and the electric structure part is made of motor side link, electronic side plate motor head and electronic side plate motor; The inner big support of side plate handrail and side plate is fixed, the upper end of last end link and following end link is hinged with the inner big support of side plate respectively, the lower end of last end link and following end link respectively with side plate on end support hinged, the inner of end support is fixed on the lathe bed framework on the side plate; The protruding end of following end link is connected with the upper end of connecting rod, the lower end of connecting rod is connected with the upper end of motor side link, the lower end of motor side link is fixed on the lathe bed framework, the front end of the centre of motor side link and electronic side plate motor head is hinged, the rear end of electronic side plate motor head is connecting electronic side plate motor, formed a linear push rod, electronic side plate motor is fixed on the lathe bed framework by the lathe bed contiguous block; Electronic side plate motor is controlled by control knob.
Optionally, described automatic armrest system can be in an electric care bed side setting.
Optionally, described automatic armrest system can be provided with in electric care bed both sides.
Control principle of the present utility model is:
Formed an eight-linkage mechanism that is hinged by side plate handrail, last end link, following end link, connecting rod, motor side link, electronic side plate motor head, electronic side plate motor, lathe bed framework, promoted by electronic side plate motor.Wherein, form a four-bar mechanism with unique degree of freedom by side plate handrail, last end link, lower link, side plate upper end support, motor side link, electronic side plate motor head, electronic side plate motor, lathe bed framework are formed a crank rocker mechanism; When the linear push rod of electronic side plate motor head and electronic side plate motor formation extended, the motor side link was counterclockwise rotatablely moving, and gave thrust that makes progress of end link down by connecting rod, and the side plate handrail that drives in the four-bar mechanism upwards boosts; Otherwise, when linear push rod shortens, the side plate handrail is descended; Therefore, as long as control the automatic lifting that just can realize the side plate handrail that turns to of electronic side plate motor.
The good effect of a kind of electric care bed automatic armrest system of this utility model is:
(1) utilizes combining of mechanical linkage structure and linear push rod, realized the automatic armrest system that matches with electric care bed function can being arranged on electric care bed one or both sides with steady elevating movement;
(2) change the deficiency that has now on the electric care bed handrail design, improved the practicality of nursing bed, made bed person control ability and increase, also can obtain better protection;
(3) replaced servomotor with linear push rod, used plane hinge mechanism, and drive mechanism, side plate handrail adopt metal material manufacturing, hinged selection standard spare screw bolt and nut, reduce production cost, helped electric care bed popularization and industrialization production.
