Description

Technical Field

[0001] The utility model relates to the technical field of hospital bed turning, in particular to an automatic turning mechanism of an electric hospital bed. Background Art

[0002] Hospital beds generally refer to nursing beds. Designed based on the patient's treatment needs and bedridden lifestyle, they allow family members to accompany the patient. Equipped with multiple nursing functions and operating buttons, they are insulated and safe, and can also be used in conjunction with treatment or rehabilitation equipment. These beds facilitate both medical observation and inspection, as well as family members' use. Automatic turning mechanisms are often used to turn paralyzed or incapable patients.

[0003] After searching the Chinese patent "An Assisted Turning Bed", the announcement number is "CN219983255U". This patent drives the first screw to disengage from the inside of the rotating plate, which can then rotate the rotating plate to lower the arc rod, thereby making it easier for patients to get in and out of bed. The two second screws are driven by two driving motors to rotate, and the rotation of the second screws drives the U-shaped plate to move. The movement of the U-shaped plate drives one end of the connecting piece to move, which can automatically lift one end of the rotating plate, thereby facilitating the turning of the patient. However, when the device turns the patient over, there is a certain friction between the patient and the turning plate. It is difficult for the patient to move on the bed after turning over, and it is inconvenient to move and adjust the position of the patient after turning over, which reduces the effectiveness of the device.

[0004] Therefore, an automatic turning mechanism for an electric hospital bed is proposed to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] When implementing: Figure 1-4 As shown, an automatic turning mechanism of an electric bed is provided, comprising a support frame 1, two first bed boards 2 being hingedly connected in the middle of the inner wall of the support frame 1, and second bed boards 3 being hingedly connected on both sides of the inner wall of the support frame 1; an adjustment mechanism 4 for facilitating rapid adjustment of the patient's position after turning over is arranged on the inner walls of the first bed board 2 and the second bed board 3; wherein the adjustment mechanism 4 comprises several rotating rods 401 evenly distributed and rotatably connected to the inner wall of the first bed board 2, the outer wall of the rotating rod 401 is transmission-connected to a first transmission belt 402, and protective components 411 are provided on both sides of the support frame 1.

[0023] like Figure 2 and Figure 3 As shown, the adjustment mechanism 4 also includes two transmission rods 403 rotatably connected to the inner wall of the second bed board 3, and a second transmission belt 404 is connected between the two transmission rods 403. A motor 405 is fixedly installed on the inner wall of the second bed board 3, and the output shaft at one end of the motor 405 is fixedly connected to one end of one of the transmission rods 403. The outer wall of the second transmission belt 404 is fixedly connected to a protective belt 406, and the outer wall of the protective belt 406 is provided with a number of evenly distributed limiting grooves 407. The inner wall of the second transmission belt 404 is provided with a number of evenly distributed support rods 408, and the support rods 408 are rotatably connected to the inner wall of the second bed board 3. Both ends of the inner wall of the support frame 1 are hinged with a first electric push rod 409, and one end of the first electric push rod 409 is hinged to the bottom end of the first bed board 2. Two second electric push rods 410 are hinged on both sides of the wall, and one end of the second electric push rod 410 is hinged to the bottom end of the second bed board 3. When adjusting the position after turning over, the motor 405 drives the second transmission belt 404 and the protective belt 406 to rotate through one of the transmission rods 403 and the other transmission rod 403 to move and adjust the patient on the second bed board 3. The limiting groove 407 on the protective belt 406 can create friction between the patient and the protective belt 406, making it convenient to move it. When the second transmission belt 404 moves, several support rods 408 are used to increase the bearing capacity of the second transmission belt 404. The rotating rod 401 cooperates with the first transmission belt 402 to enable the first bed board 2 to move the patient's position, which is convenient for moving and adjusting the patient's position after turning over.

[0024] like Figure 4As shown, the protection assembly 411 includes protection blocks 4111 arranged on both sides of the top of the support frame 1, and two third electric push rods 4112 are fixedly installed on the inner wall of the protection block 4111, and one end of the third electric push rod 4112 is fixedly connected to the protection plate 4113. A placement groove 4114 is provided on both sides of the support frame 1, and the inner wall of the placement groove 4114 is hinged with several evenly distributed connecting rods 4115, and one end of the connecting rod 4115 is hinged to the protection block 4111. When the patient is turned over, one end of the third electric push rod 4112 in the protection block 4111 extends to one side to drive the protection plate 4113 to move to one side, supporting the patient's body when turning over. The flexibility of the protection plate 4113 itself can prevent injury to the patient. The connecting rod 4115 is hinged to the protection block 4111 and the placement groove 4114 at both ends and rotates to one end to store the protection block 4111, which can improve the safety of the bed and improve the turning effect of the bed.

[0025] When the utility model is in use, the protective blocks 4111 on both sides of the support frame 1 are pulled to drive the connecting rod 4115 to open from the placement slot 4114 to protect the patient. The second electric push rod 410 is driven by the controller. One end of the second electric push rod 410 extends to one side and cooperates with the bottom end of the second bed board 3 to drive one end thereof to rotate and tilt upward to turn the patient over. The third electric push rod 4112 is driven by the controller to drive one end of the protective plate 4113 to extend to one side to support the patient's body during the turning process. After the turning is completed, the third electric push rod 411 2 drives the protective plate 4113 back to its original position, and the controller drives one of the transmission rods 403 to rotate. One of the transmission rods 403 and the other transmission rod 403 drive the protective belt 406 on the outer wall of the second transmission belt 404 to rotate, thereby moving the patient on the second bed board 3. The multiple rotating rods 401 in the first bed board 2 cooperate with the first transmission belt 402 to rotate, thereby adjusting the position of the patient.
