Problems solved by technology

[0002] At present, the sickbeds used in hospitals have single functions and can only be used for patients to rest in bed. Although more advanced sickbeds also have backrest lifting mechanisms, the handwheels are set at the feet of the sickbed. To make the patient sit up, the nursing staff must walk to the sickbed. When the patient sits up, the nursing staff cannot touch the patient, and the patient has no sense of security. At the same time, the existing lifting mechanism has a complex structure, the length of the screw rod is too large, and the cost is high. This structure cannot be used on the sleeper beds used in long-distance buses, and the use is greatly restricted

example 1

[0013] Example 1: The electric rotating device of the backrest of the bed of the present invention comprises a bed frame 1, a back frame 2 and an electric pusher, the right end of the backrest frame 2 is rotatably fixed on the bed frame 1 by a rotating pin 11, and the electric pusher Composed of motor 10, transmission wheel 9, transmission shaft 8, movable nut seat 7, bevel gear nut 6, bevel gear 5 and screw mandrel 4, transmission wheel 9 and bevel gear 5 are all installed on transmission shaft 8, transmission shaft 8 can be It is rotatably fixed on the bed frame 1; the center of the bevel gear nut 6 is provided with an internal thread, and its lower end is provided with a shaft shoulder, which is installed on the bearing seat 72 through the bearing 71, and the bevel gear nut 6 is rotatable relative to the bearing seat 72 , the bearing seat 72 is reversibly fixed on the support plate 75 by two screws 73 and the fixed ring 74, the support plate 75 is fixed on the bed core frame...

example 2

[0014] Example 2: Similar to the structure of Example 1, the difference is that the bevel gear 5 is directly installed on the main shaft of the motor 10, and the motor 10 is fixed on the bed frame 1, and the transmission shaft 8 is omitted in this example.

Abstract

An electric back rest driver of bed is composed of a bed frame, a back rest frame with a right end fixed to the said bed frame in a turnable mode, and an electric drive unit arranged between said bed frame and back rest frame and consisting of self-locking leading screw-nut mechanism, motor, and bevel gears.

Description

Technical field: [0001] The invention relates to a bed. Background technique: [0002] At present, the sickbeds used in hospitals have single functions and can only be used for patients to rest in bed. Although more advanced sickbeds also have backrest lifting mechanisms, the handwheels are set at the feet of the sickbed. To make the patient sit up, the nursing staff must walk to the sickbed. When the patient sits up, the nursing staff cannot touch the patient, and the patient has no sense of security. At the same time, the existing lifting mechanism has a complex structure, the length of the screw rod is too large, and the cost is high. This structure can not be used on the used sleeper bed on the long-distance bus, and the use is greatly restricted. Invention content: [0003] The purpose of the present invention is to provide an electric rotating device for the backrest of a bed. [0004] The electric rotating device for the backrest of the bed according to the presen...
