Referring to fig. 1 to 6, the present invention provides a nursing bed with an electric armrest, comprising: a foldable bed 1, a base 2 and a handrail assembly 3; the foldable bed 1 comprises a leg 11, a basin bottom 12 and a backrest 13, wherein the basin bottom 12 is hinged between the leg 11 and the backrest 13,

The base 2 comprises a base 21, a first driving piece 22 and a second driving piece 23, wherein two ends of the first driving piece 22 are respectively hinged to the leg placing portion 11 and the base 21 of the foldable bed 1, two ends of the second driving piece 23 are respectively hinged to the backrest portion 13 and the base 21 of the foldable bed 1, the first driving piece 22 can drive the leg placing portion 11 to move so as to keep the leg placing portion 11 and the basin bottom 12 in a horizontal or inclined state, and the second driving piece 23 can drive the backrest portion 13 to move so as to keep the backrest portion 13 and the basin bottom 12 in a horizontal or inclined state;

the armrest assembly 3 includes a third drive 31, an invert arm 32, and an armrest 33; the turnover arm 32 is mounted on the base 21 and connected to the armrest 33, and the third driving member 31 is hinged to the base 21 and the turnover arm 32.

Thus, when the third driving member 31 extends out and drives the armrest 33 to turn upwards through the turning arm 32, the armrest 33 stands on the side of the nursing bed along with the turning upwards movement, so that the patient is prevented from sliding off the foldable bed body 1; on the contrary, when the third driving member 31 is retracted, the arm rest 33 is driven to turn down by the turning arm 32, and the arm rest 33 is turned down accordingly, the arm rest 33 can be automatically driven to turn down by the third driving member 31, so that the arm rest is located below the foldable bed body, the bed width is reduced, and the original manual operation mode is replaced, so that the use is convenient.

When the leg placing part 11, the basin bottom 12 and the backrest part 13 are all kept in a horizontal state, the patient can conveniently lie on the foldable bed body 1 for recuperation, and when the leg placing part 11 and the basin bottom 12 are kept in an inclined state and the backrest part 13 and the basin bottom 12 are kept in an inclined state, the patient can conveniently sit on the foldable bed body 1 for recuperation, and the patient can be conveniently recuperated without the assistance of special nursing staff.

In a preferred embodiment, the armrest assembly 3 further includes a fixing frame 34 and a connecting rod 35, the turnover arm 32 includes a mounting plate 321 and a turnover plate 322 hinged to the mounting plate 321, the fixing frame 34 is mounted on the base 21, the mounting plate 321 is fixedly connected to the fixing frame 34, one end of the turnover plate 322 is fixedly connected to the armrest 32, the connecting rod 35 is connected to the turnover plate 322, and two ends of the third driving member 31 are respectively hinged to the fixing frame 34 and the connecting rod 35. It should be noted that, in this embodiment, the number of the armrests 33, the third driving members 31, and the connecting rods 35 is two, the number of the overturning arms 32 is plural, the third driving members 31 are simultaneously hinged to the plurality of overturning arms 32 through the connecting rods 35, the first driving members 22, the second driving members 23, and the third driving members 31 are all electric cylinders, the first driving members 22, the second driving members 23, and the third driving members 31 are all electrically connected with a controller (e.g., an industrial personal computer), the controller can be arranged at one side of the foldable bed body 1, and the industrial personal computer sends out an operation command to adjust the telescopic state of the first driving members 22, the second driving members 23, and the third driving members 31.

Thus, when the third driving member 31 extends, the third driving member 31 extends to drive the armrest 33 to move upwards in a turnover manner through the turnover arm 32, so that the armrest 33 is erected on one side of the foldable bed 1, and the patient is prevented from sliding off the foldable bed 1; on the contrary, when the third driving member 31 is retracted, the third driving member 31 drives the armrest 33 to turn downward through the turning arm 32, so that the armrest 33 is drooped and perpendicular to the foldable bed body 1, and the patient can conveniently get out of the bed. In use, the handrail 33 can be adjusted by the third driving member 31 according to actual requirements.

In a preferred embodiment, the connection between the turning piece 322 and the armrest 33 is provided with a fixing block 36, and the fixing block 36 increases the strength between the turning piece 322 and the armrest 33, so as to avoid the problem that the armrest 33 is easy to loosen after long-term use.

In a preferred embodiment, the foldable bed 1 further comprises a foot rest 5, the foot rest 5 being hinged to the leg rest 11 and located at an end remote from the basin bottom 12, the foot rest 5 being able to be kept horizontal or inclined with respect to the leg rest 11. Thus, when the patient is sitting, the foot pad part 5 and the leg placing part 11 are kept in an inclined state, and the patient can place the feet on the foot pad part 5, thereby increasing the comfort of the patient.

In a preferred embodiment, the seat 21 is provided with a headboard 211 and a baffle 212 at both ends of the foldable bed 1, respectively, and the headboard 211 is located outside the backrest 13 when the backrest 13 is maintained in a horizontal state. Therefore, the foot part of the patient can be prevented from being injured by other objects and the head part of the patient can be prevented from being injured by other objects, and the protection function can be achieved.

In a preferred embodiment, the base 21 is provided with a telescopic moving member 213 (e.g., a ball screw) and a head mount 214, and the head mount 214 is connected between the headboard 211 and the telescopic moving member 214 and is located on the base 21. When the backrest 13 falls down to be kept in a horizontal state, the telescopic moving member 214 is extended to move the headboard 211 away from the backrest 13 so as to fall down the backrest 13, the backrest 13 is prevented from being impacted on the headboard 211, and then the telescopic moving member 214 is retracted to move the headboard 211 in a direction approaching the backrest 13, so that the headboard 211 is abutted on the backrest 13.

In a preferred embodiment, the electric folding care bed further comprises a differential wheel set 6 and a universal wheel 7, wherein the differential wheel set 6 is mounted on the base 21 and located at the rear end of the base 21, and the universal wheel 7 is mounted on the base 21 and located at the front end of the base 21. The number of differential wheel sets 6 and universal wheels 7 is two. When the differential wheel set 6 is started, the electric folding nursing bed can be pushed to move.

When the foldable bed is used, the first driving piece 22 drives the leg placing part 11 to move so that the leg placing part 11 and the basin bottom 12 are kept in a horizontal state, and the second driving piece 23 drives the backrest part 13 and the basin bottom 12 to be kept in a horizontal state, so that a patient can conveniently lie on the foldable bed body 1 for recuperation. When the first driving part 22 drives the leg 11 to move so that the leg 11 and the basin bottom 12 are kept in an inclined state, and the second driving part 23 drives the backrest 13 and the basin bottom 12 to be kept in an inclined state, and when the backrest 13 and the basin bottom 12 are kept in an inclined state, a patient can conveniently sit on the foldable bed body 1 for recuperation, and a special nursing staff is not needed any more to assist the patient to complete the movement from the lying posture to the sitting posture, so that the multifunctional nursing bed is very convenient to be applied to patient nursing.
