Detailed implementation manners
[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] Please refer to Figures 1-9 , the present invention provides a technical solution: an electric hospital bed backboard structure with a lifting function, including a first support backboard 1. In this case, the keel connecting plate 2 is installed inside the first support backboard 1. In this case, the flipping part 3 is installed on one side of the keel connecting plate 2 for automatically positioning the patient's back. In this case, the fitting part 4 is installed on the keel connecting plate 2 for adjusting the angle of the patient's head. In this case, the adjusting part 5 is installed on the keel connecting plate 2 for adjusting the patient's nursing posture. In this case, the limiting part 6 is installed on the flipping part 3 for limiting the patient's waist.
[0036] In this embodiment, in order to further automatically position the patient's back and facilitate nursing, the flipping part 3 in this case includes a flipping plate 31. A hinge groove 32 is opened on the flipping plate 31. A first hinge plate 33 is hinged to the inner wall of the hinge groove 32. The bottom end of the first hinge plate 33 is hinged to a second hinge plate 34. The bottom end of the second hinge plate 34 is hinged to a hinge sliding seat 35. The bottom of the first support backboard 1 is fixedly connected with a limit sliding plate 36. The outer wall of the hinge sliding seat 35 is slidably connected to the limit sliding plate 36.
[0037] In order to further adjust the comfortable angle of the patient's head, the fitting part 4 in this case includes a headrest plate 41.

The top of the headrest plate 41 is fixedly connected with a headrest soft pad 45. After the headrest plate 41 is automatically adjusted, the headrest soft pad 45 supports the patient's head.
[0038] In order to further limit and support the patient's waist and abdomen, the limiting part 6 in this case includes a receiving slide groove 61. The receiving slide groove 61 is an arc-shaped structure. The receiving slide groove 61 is opened on the side wall of the flip plate 31. The inner wall of the receiving slide groove 61 is slidably connected to the limiting clamp 63. The limiting clamp 63 is an arc-shaped structure matching the receiving slide groove 61, so that the limiting clamp 63 can slide in a curve in the receiving slide groove 61. A spring 62 is elastically connected between the inner wall of the receiving slide groove 61 and the limiting clamp 63. The end of the limiting clamp 63 away from the spring 62 abuts against the inner wall of the ear end of the supporting back plate 1. After adjustment by the flip plate 31, the spring 62 elastically pushes the limiting clamp 63 to limit and support the patient's waist and abdomen.
[0039] It is worth noting that in order to further correct the patient's back posture, the adjustment part 5 of this case includes a connecting back plate 51, a motor 52 is fixedly connected to the connecting back plate 51, a rotating shaft 53 is fixedly connected to the output end of the motor 52, a gear 1 54 is fixedly connected to the outer wall of the rotating shaft 53, a gear 2 55 is meshingly connected to the outer wall of the gear 1 54, the diameters of the gear 1 54 and the gear 2 55 are the same, a rotating rod 56 is fixedly connected to the inner wall of the gear 2 55, and both ends of the rotating rod 56 are rotatably connected to the connecting back plate 51, and the supporting back plate 1 is a U-shaped structure. The two ear ends of 1 are fixedly sleeved on the outer wall of the rotating rod 56, the adjusting part 5 also includes a gear three 57, the diameter of the gear three 57 is larger than the gear one 54, the gear three 57 is fixedly connected to the outer wall of the rotating shaft 53, the outer wall of the gear three 57 is meshedly connected with a gear four 58, the diameter of the gear four 58 is smaller than the gear one 54, one end of the keel connecting plate 2 is fixedly connected with a connecting block one 59, the gear four 58 is fixedly connected to the outer wall of the connecting block one 59, the gear four 58 is movably sleeved on the outer wall of the rotating rod 56, and the axis of the gear four 58 is aligned with the center of the circle of the gear two 55.
[0040] It is worth mentioning that in order to distinguish it from traditional electric beds, special structural improvements are made to the existing lifting backboard. In this case, the outer wall of the connecting backboard 51 is fixedly connected to a supporting backboard 7, and the outer wall of the supporting backboard 7 is hinged with a leg support plate. The outer wall of the keel connecting plate 2 is fixedly connected to a connecting block 8, and the headrest plate 41 is hinged to the connecting block 8. Both sides of the keel connecting plate 2 are fixedly connected with connecting rods 9. There are two flipping parts 3, and the other flipping part 3 is symmetrically arranged on the other side of the keel connecting plate 2. The two flipping plates 31 are respectively rotatably sleeved on the outer walls of the two connecting rods 9, and two supporting base plates 10 are symmetrically installed between the two ear ends of the supporting backboard 1. The tops of the two supporting base plates 10 are fixedly connected with support strips, and the support strips on each supporting base plate 10 are respectively fitted with the two sides of the bottom of the flip plate 31 on the same side.
[0041] Working principle: The device in this case is arranged on the existing hospital bed board. The connecting backboard 51 and the supporting backboard two 7 are both installed on the existing hospital bed frame. The limiting slide plate 36 abuts against the top of the existing hospital bed board. When nursing a patient, by starting the motor 52, the output end of the motor 52 drives the rotating shaft 53 to rotate, causing the meshing-connected gear one 54 and gear two 55 to rotate. Thus, the supporting backboard one 1 is driven to flip and lift through the rotating rod 56, and the patient can be adjusted to the specified nursing angle. While the rotating shaft 53 is rotating, the gear three 57 drives the meshing-connected gear four 58 to rotate, and the keel connecting plate 2 can be flipped and adjusted through the connecting block one 59. At this time, the flipping angle of the keel connecting plate 2 is greater than that of the supporting backboard one 1. When the keel connecting plate 2 flips, under the hinged action of both ends of the hinge plate three 43 with the hinge fixed seat one 42 and the hinge fixed seat two 44 respectively, the hinge plate three 43 pulls the headrest plate 41 to flip around the connecting block two 8 as the axis until the angle between the hinge plate three 43 and the headrest plate 41 is 180 degrees, and the included angle between the headrest plate 41 and the keel connecting plate 2 is 90 degrees, thereby providing a comfortable reclining angle for the patient's head, helping to prevent neck discomfort caused by improper head postures when the patient sits or lies down, and improving the comfort and quality of life of the patient during bed rest. When the motor 52 rotates in reverse, the keel connecting plate 2 resets to the inner wall of the supporting backboard one 1. The supporting bottom plate 10 can stably support both ends of the flipping plate 31, making the two side flipping plates 31 and the keel connecting plate 2 in a horizontal posture, precisely adjusting the patient's backrest posture, keeping the spine on the normal physiological curve, and avoiding spinal deformation caused by long-term incorrect lying postures.
[0042] When the keel connecting plate 2 flips, since the deflection angle of the keel connecting plate 2 is greater than that of the supporting backboard one 1, the two side flipping plates 31 on the keel connecting plate 2 will move away from the supporting backboard one 1. At this time, the hinge sliding seat 35 will slide along the top of the limiting slide plate 36, prompting the hinge plate two 34 to pull the hinge plate one 33 and simultaneously pulling the flipping plate 31 to flip around the connecting rod 9 as the axis, so that a V-shaped structure is formed between the two side flipping plates 31 and the keel connecting plate 2, automatically limiting the patient's back, avoiding various postures that are not conducive to nursing during patient care, and facilitating the nursing operation of medical staff on the patient. When the flipping plate 31 flips out of the inner wall of the supporting backboard one 1, the spring 62 elastically pushes out the limiting clamp block 63. At this time, the limiting clamp block 63 slides to the patient's waist and abdomen position in an arc trajectory, and the two limiting clamp blocks 63 further limit both sides of the patient's waist and abdomen, thereby further correcting the patient's reclining posture, reducing the workload of manually adjusting the patient's posture, improving the nursing efficiency, and ensuring the stability of the patient during nursing.
