The back bed board is connected and can raises and set level with bolt 15 between the buttocks bed board framework by its framework, realizes bed person's sitting posture, lying posture or sleeping position.
In down podical plate 6 be active, can move, drain to make things convenient for bed person.
Referring to accompanying drawing 2.An electric care bed lateral blocked frame 12, head board 13, tailstock plate 14, bottom bedstead 16, middle level bedstead 17, the top layer bedstead 18 of comprising that this utility model relates to; Bed lateral blocked frame 12 has four, respectively is provided with two in the both sides of nursing bed, and bed lateral blocked frame 12 is by can individually holding up or put down with being connected of top layer bedstead 18.
Linear push rod 21, linkage are arranged under the combination type bed board, between middle level bedstead 17 and the top layer bedstead 18.
Referring to accompanying drawing 3～5.This utility model is provided with two linear push rods, two cover linkages and two rollover rotating shafts between middle level bedstead 17 and top layer bedstead 18.
Linear push rod 21 is made up of 24V voltage motor, worm and worm gear and trapezoidal screw mechanism, drives the right side and the left side bed board moves by linkage, for rollover of the present utility model mechanism provides linear reciprocating power; During energising, linear push rod 21 promotes linkage rotates a side plate, and linear push rod 21 stops during outage, and each connecting rod of the linkage that is driven does not have relative motion, all remains static.Two linear push rods of the present utility model, a wide-angle rollover of promoting mainly right dorsal plate 1 and right buttocks side plate 4, a wide-angle rollover of promoting mainly left dorsal plate 3 and left buttocks side plate 7.
Linkage comprises: side link I 22 (seeing accompanying drawing 8), connecting rod I 23 (seeing accompanying drawing 7), side link II 24 (seeing accompanying drawing 6), connecting rod II 25 (seeing accompanying drawing 9), side link III26 (seeing accompanying drawing 11), side link IV 27 (seeing accompanying drawing 12), connecting rod III 28 (seeing accompanying drawing 10), relate to middle level bedstead 17 and top layer bedstead 18 (mainly being as rack section), side link wherein is the revolving member that has an end to be connected with middle level bedstead 17 or top layer bedstead 18.
The rollover rotating shaft is arranged on backboard, podical plate and the middle backboard of homonymy, the hinged place of middle buttocks plate framework, a right side that is arranged on nursing bed, and another is arranged on the left side of nursing bed.
One end of linear push rod 21 is fixed on the middle level bedstead 17, the other end is connected with side link I 22, side link I 22 is connected with side link II 24 by connecting rod I 23, the promotion of linear push rod 21 makes the rollover rotating shaft (not shown) motion of side link II 24 around this side, crank throw by this side makes the backboard of this side become the wide-angle rollover together with podical plate with the rollover rotating shaft, and the amplitude of rollover can reach 85 °; Meanwhile, side link I 22 is connected with side link III 26 by connecting rod II 25, side link III 26 connects side link IV 27 by connecting rod III 28 again, and the promotion of linear push rod 21 makes the rollover rotating shaft (not shown) motion of side link IV 27 around opposite side; Crank throw by this side makes the backboard of this side become the low-angle rollover together with podical plate with the rollover rotating shaft, and the amplitude of rollover can reach 15 °; The large and small angle rollover here is synchronous interaction.
Because described left and right side backboard and left and right buttocks side plate all are relatively independent bed board modules, this utility model has adopted the crank throw structure, its holder lining is at left dorsal plate 3 and left buttocks side plate 7, or under the framework of right dorsal plate 1 and right buttocks side plate 4, make it when the rollover motion, to be integral and synchronously lift or put down.
Linkage of the present utility model is that the input of single action power---a linear push rod promotes, and the rollover rotating shaft of twin shaft---both sides is exported synchronously, has realized upwards turning on one's side synchronously or putting down of left and right sides bed board.Right side bed board corner was greater than the left side corner when turned in the left side, and left side bed board corner was greater than the right side corner when turned on the right side; The side bed board that corner is bigger during rollover plays the upset human body, and the less side bed board of corner guarantees to move outside mattress and human body are; The position that both sides synergy movement is simultaneously guaranteed bed person to turn on one's side steadily, safely hope accomplished.
Drive mechanism of the present utility model, frame, bed board frame adopt metal material and/or composite manufacturing, the hinged standard component such as screw bolt and nut of selecting for use, and technology is easy, is beneficial to the popularization and the large-scale production of product.
