[0024] In some embodiments, see Figures 1 to 4 A first supporting longitudinal plate 11 and a second supporting longitudinal plate 12 are respectively provided at the front and rear ends of the lower end surface of the bed board 1. The turning area is located on the side close to the first supporting longitudinal plate 11. In actual application, the first supporting longitudinal plate 11 and the second supporting longitudinal plate 12 are bolted and fixed to the bed board 1. The first supporting longitudinal plate 11 and the second supporting longitudinal plate 12 are used to support the bed board 1 on the ground. In order to ensure the strength of the overall structure, a connecting beam 13 is provided between the first supporting longitudinal plate 11 and the second supporting longitudinal plate 12. In this embodiment, the number of the connecting beams 13 is two, and the two connecting beams 13 are symmetrically arranged on the left and right.

[0025] In some embodiments, see Figures 1 to 4, a mounting hole 101 is provided on the above-mentioned turning area. In this embodiment, the mounting hole 101 is a rectangular hole that passes through the bed board 1 from top to bottom. A turning plate 3 is provided in the mounting hole 101. The end of the turning plate 3 close to the second supporting longitudinal plate 12 is hinged to the bed board 1, and the end of the turning plate 3 close to the first supporting longitudinal plate 11 is hinged to the first longitudinal plate through a telescopic component. In this embodiment, the telescopic component is an electric telescopic rod 14, and the rotating shaft 4 is arranged on the turning plate 3. The rotating shaft 4 is connected to the driving end of the first servo motor 5 through a telescopic universal coupling 42. Through the above arrangement, when the elderly need to sit up from the bed board 1 to rest, the electric telescopic rod 14 can be extended by operating the electric telescopic rod 14 to drive the turning plate 3 to rotate upward, so that the elderly can sit up from the bed board 1 with the help of the thrust of the turning plate 3. In this embodiment, through the connection of the telescopic universal coupling 42, the rotating shaft 4 can still maintain a reliable connection with the driving end of the first servo motor 5 when rotating with the turning plate 3.

[0026] For details, please refer to Figures 2 to 4 There is a passing gap between the left and right edges of the flip plate 3 and the side walls of the mounting hole 101, and first mounting plates 41 are relatively arranged at the front and rear ends of the left and right sides of the lower end surface of the flip plate 3. The rotating shaft 4 is rotatably connected between the two first mounting plates 41, and the end of the rolling curtain 2 passes through the passing gap and is wound around the rotating shaft 4. The first servo motor 5 is installed on the side of the lower end surface of the bed board 1 close to the second supporting longitudinal plate 12. One end of the rotating shaft 4 close to the second supporting longitudinal plate 12 passes through the first mounting plate 41 on the same side, and is connected to the driving end of the first servo motor 5 through a telescopic universal coupling 42.

[0027] In some embodiments, see Figures 2 to 4 The left and right ends of the flip plate 3 are rotatably connected with guide rollers 34 respectively. In application, the rolling curtain 2 passes around the guide rollers 34 and then passes through the gap to be wound on the rotating shaft 4. A positioning groove 31 is provided in the middle of the flip plate 3. The positioning groove 31 is a through groove that penetrates the upper end surface of the flip plate 3 in the left and right directions. The rolling curtain 2 is laid in the positioning groove 31. The positioning groove 31 can limit the forward and backward movement of the rolling curtain 2. In addition, the depth of the positioning groove 31 is equivalent to the thickness of the rolling curtain 2. In this way, after the rolling curtain 2 is laid in the positioning groove 31, its upper end surface can be flush with the upper end surface of the flip plate 3, thereby improving the comfort of the elderly when lying down.

[0028] In some embodiments, see Figure 2 and Figure 5 A protrusion 32 is protruded outward on the left and right sides of one end of the flip plate 3 close to the first supporting longitudinal plate 11, and a groove 102 is provided on the side wall of the mounting hole 101 corresponding to the protrusion 32. The groove 102 penetrates the side wall of the mounting hole 101 upward. When the flip plate 3 is in a horizontal state, the protrusion 32 abuts against the bottom of the groove 102 to limit the flip plate 3 from rotating downward.

[0029] In some embodiments, see Figures 2 to 6 A first moving part that moves in the left-right direction is provided below the flip plate 3, and a lifting assembly is connected to the first moving part. A avoidance hole 33 for the moving end of the lifting assembly to pass through is provided on the flip plate 3 corresponding to the moving path of the first moving part. The moving end of the lifting assembly rises to lift the rolling curtain 2 to form an obstacle 9 on the flip plate 3. In this embodiment, there are two first moving parts, and the two first moving parts are relatively arranged on the left and right sides of the flip plate 3.

[0030] Specifically, second mounting plates 37 are relatively arranged on the left and right sides of the lower end surface of the flip plate 3, a first guide rail 36 is arranged between the two second mounting plates 37, and a first action component is slidably connected to the first guide rail 36. The first action component includes a sliding block 6 and a second servo motor 61. The sliding block 6 is penetrated through the first guide rail 36 and is slidably connected to the first guide rail 36. In the present embodiment, the first guide rail 36 is an inverted T-shaped beam connected to the two second mounting plates 37. A sliding groove matching the inverted T-shaped beam is provided on the sliding block 6. With the help of the sliding groove, the sliding block 6 can be slidably penetrated through the first guide rail 36. A rack is provided on the first guide rail 36 along its length. The second servo motor 61 is fixed on the sliding block 6. A driving gear 62 is provided at the driving end of the second servo motor 61. The driving gear 62 is meshed with the rack. The second servo motor 61 is used to drive the sliding block 6 to slide on the first guide rail 36.

[0031] In this embodiment, the lifting assembly includes a lifting motor 7, the fixed end of the lifting motor 7 is connected to the sliding block 6, the lifting end of the lifting motor 7 is connected to a support bracket 71, and a support roller 72 is rotatably connected to the support bracket 71. In this embodiment, the length direction of the support roller 72 is consistent with the front and rear reverse direction of the bed board 1, and the rotation direction of the support roller 72 is consistent with the moving direction of the rolling curtain 2. In application, the support roller 72 is used to contact the rolling curtain 2. In order to improve the supporting strength of the first guide rail 36, a connecting block 35 is provided in the middle of the lower end surface of the flip plate 3, and the middle part of the first guide rail 36 is penetrated on the connecting block 35, and two sliding blocks 6 are respectively located on the left and right sides of the connecting block 35.

[0032] In practical applications, the device provided by the present invention has two practical operation modes. For the first practical operation mode, please refer to Figure 7When the human body 8 lies in the turning area to rest, the caregiver can control the two second servo motors 61 to move the sliding block 6, so that the two lifting motors 7 are respectively located at the left and right edges of the turning plate 3, and then start the two lifting motors 7 respectively to make the support roller 72 rise upward, and push the rolling curtain 2 upward to form an obstacle part 9. It should be understood that while the support roller 72 pushes the rolling curtain 2 upward, the first servo motor 5 located on the same side will rotate at the same time, releasing the rolling curtain 2 wound on the reel to compensate for the increased length of the rolling curtain 2 when the support roller 72 pushes the rolling curtain 2. After the two obstacle parts 9 are formed, the resting human body 8 is located between the two obstacle parts 9, and the two obstacle parts 9 hinder the left and right movement range of the human body 8, thereby preventing the elderly from falling out of bed.

[0033] For the second practical method, see Figure 8 When the elderly are turning over, the caregiver can also control the two second servo motors 61 to move the sliding blocks 6, so that the two lifting motors 7 move to the left and right sides of the human body 8 respectively, and then start the lifting motors 7. When the human body 8 needs to turn over to the left, the lifting motor 7 on the right side of the human body 8 is raised to a higher height, and the lifting motor 7 on the left side of the human body 8 is raised to a lower height. In this way, a high obstacle part 9 and a low obstacle part 9 can be obtained. At this time, the first servo motor 5 is started again to move the roller blind 2 to the right. The human body 8 moves to the right with the roller blind 2 and is hindered by the high obstacle part 9 on the right side, and will turn over to the left. At this time, the low obstacle part 9 on the left side of the human body 8 can form an obstacle to the body of the human body 8 to prevent the human body 8 from turning over excessively. After the turning over is completed, the first servo motor 5 can be stopped.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
