[0039] like Figure 1-Figure 3As shown, in this embodiment, a smart bed includes a load-bearing frame 1, a lifting and translation mechanism 2, a back plate 3, a bed support plate 4 and a driving mechanism 5. The lifting and translation mechanism 2 is movably connected to the load-bearing frame 1, the back plate 3 is arranged on the lifting and translation mechanism 2, the bed support plate 4 is arranged on the load-bearing frame 1, the first end of the driving mechanism 5 is arranged on the load-bearing frame 1, and the second end of the driving mechanism 5 is connected to the back plate 3. Under the action of the driving mechanism 5, the lifting and translation mechanism 2 controls the back plate 3 to perform a curved motion relative to the load-bearing frame 1, so that the back plate 3 is in a supine state with an inclined arrangement relative to the bed support plate 4, and the end of the back plate 3 close to the bed support plate 4 gradually moves away from the bed support plate 4.

[0040] Specifically, the load-bearing frame 1 is placed on the floor of the bedroom, and the lifting and translation mechanism 2 includes a first connecting rod 21 and a second connecting rod 22, the length of the second connecting rod 22 is greater than or equal to the length of the first connecting rod 21, the first connecting rod 21 is arranged close to the bed support plate 4, and the two ends of the first connecting rod 21 are respectively rotatably connected to the load-bearing frame 1 and the end of the back plate 3 close to the bed support plate 4, and the second connecting rod 22 is arranged away from the bed support plate 4, and the two ends of the second connecting rod 22 are respectively rotatably connected to the end of the load-bearing frame 1 close to the wall and the middle of the back plate 3. From the foot of the bed to the head of the bed, the bed support plate 4 and the back plate 3 are arranged on the load-bearing frame 1 in sequence, and the back plate 3 is movably arranged on the lifting and translation mechanism 2 relative to the load-bearing frame 1 and is used to at least support the back, and the bed support plate 4 is fixed relative to the load-bearing frame 1 and is used to at least support the buttocks. The driving mechanism 5 is installed on the load-bearing frame 1 and is used to drive the back panel 3 to move. The driving source of the driving mechanism 5 is a push rod motor. The second end of the driving mechanism 5 is connected to the back panel 3 and is used to drive the back panel 3 to switch between a supine state and a lying flat state.

[0041] Furthermore, the lifting and translation mechanism 2 further includes an extension member 23, which is disposed at the leading end of the load-bearing frame 1, and the first end of the second connecting rod is rotatably connected to the extension member 23. Specifically, the extension member 23 is configured as a sheet metal member, which is fixedly mounted at the end of the load-bearing frame 1 close to the wall, and the extension member 23 is rotatably matched with one end of the second connecting rod through a pin shaft, serving as a support point of the second connecting rod during movement.

[0042] The specific working principle of the smart bed is as follows: in the lying state, the back plate 3 and the bed support plate 4 are at the same horizontal plane, and the back plate 3 is in a lying state at this time, which is convenient for people to lie flat and rest. When the person needs to lie half-lying on his back, under the driving action of the driving mechanism 5, the lifting and translation mechanism 2 moves to the right against the wall relative to the load-bearing frame 1 and gradually rises and moves in a curve, which plays the role of lifting the abdomen. At the same time, the lifting and translation mechanism 2 drives the back plate 3 to lift relative to the load-bearing frame 1 and gradually translates toward the wall and moves in a curve, so that the back plate 3 is in a supine state with an inclined setting relative to the bed support plate 4, and the end of the back plate 3 close to the bed support plate 4 gradually moves away from the bed support plate 4, which can reduce the abdominal pressure when the back is raised, so that the abdomen of the human body is relieved, the comfort of use is improved, and the soothing effect is good.

[0043] Further, continue to refer to Figure 1-Figure 3 The driving mechanism 5 includes a linear driver 51, a first end of the linear driver 51 is arranged on the load-bearing frame 1, and a second end of the linear driver 51 is movably connected to the back plate 3. The linear driver 51 can drive the back plate 3 to lie in a supine state with an inclined setting relative to the bed support plate 4, and the end of the back plate 3 close to the bed support plate 4 gradually moves away from the bed support plate 4. Specifically, when a person needs to lie in a semi-reclining supine state, under the driving action of the linear driver 51, the lifting and translation mechanism 2 moves to the right against the wall relative to the load-bearing frame 1 and gradually rises and moves in a curve, which plays a role in lifting the abdomen. At the same time, the lifting and translation mechanism 2 drives the back plate 3 to lift relative to the load-bearing frame 1 and gradually translates toward the wall and moves in a curve, so that the back plate 3 is in a supine state with an inclined setting relative to the bed support plate 4, and the end of the back plate 3 close to the bed support plate 4 gradually moves away from the bed support plate 4, reducing the abdominal pressure when the back is raised, so that the abdomen of the human body is relieved, improving the comfort of use, and the relief effect is good.

[0044] Further, continue to refer to Figure 1-Figure 3 The driving mechanism 5 further includes a mounting frame 52, which is disposed on the bottom surface of the back plate 3 facing the load-bearing frame 1, and the second end of the linear driver 51 is movably connected to the mounting frame 52. Specifically, the mounting frame 52 is provided with an anti-collision portion 521, which is used to avoid the linear driver 51 and prevent interference and collision with the linear driver 51.

[0045] In other embodiments, continue to refer to Figure 4The driving mechanism 5 includes a linear driver 51, a connecting frame 53 and a rotating member 54. The second end of the linear driver 51 is movably connected to the connecting frame 53. The connecting frame 53 is rotatably connected to the load-bearing frame 1 and the rotating member 54 respectively. The rotating member 54 rotatably supports the back plate 3. Specifically, the rotating member 54 is configured as a roller. The connecting frame 53 includes a connecting rod 531 and a cross bar 532. The middle part of the cross bar 532 is movably connected to the second end of the linear driver 51. The connecting rod 531 is connected to the end of the cross bar 532. The first end of the connecting rod 531 is rotatably connected to the load-bearing frame 1. The second end of the connecting rod 531 is rotatably connected to the rotating member 54. When a person needs to lie half-lying on his back, the linear driver 51 drives the cross bar 532. At the same time, the second end of the linear driver 51 rotates relative to the cross bar 532, and the cross bar 532 drives the connecting rod 531 to move. The connecting rod 531 drives the rotating part 54 to roll along a straight line on the back plate 3, thereby pushing the back plate 3 to rise and gradually translate toward the wall, reducing the abdominal pressure when the back is raised and improving the comfort of use.

[0046] Further, continue to refer to Figure 4 The connecting frame 53 further includes a reinforcing rod 533, a support 534 and a guide rail 55. The two ends of the reinforcing rod 533 are respectively fixedly connected to the connecting rod 531 and the cross bar 532, and the reinforcing rod 533, the connecting rod 531 and the cross bar 532 are arranged in a triangular structure. The support 534 is fixedly connected to the middle of the cross bar 532, and the support 534 is rotatably connected to the second end of the linear drive 51 through a rotating shaft. The guide rail 55 is extended and arranged on the bottom surface of the back plate 3 facing the load-bearing frame 1. The rotating member 54 is located in the guide rail 55 and can slide along the length direction of the guide rail 55. Specifically, the reinforcing rod 533 is used to enhance the structural strength between the connecting rod 531 and the cross rod 532 to avoid bending. In order to ensure that the rotating member 54 can roll in a straight line direction on the back panel 3, the cross rod 532 and the connecting rod 531 are pushed under the drive of the linear driver 51, thereby driving the rotating member 54 to slide in the guide rail 55 along the length direction of the guide rail 55. The back panel 3 can be lifted and gradually translated toward the wall, so that the back panel 3 is in a supine state with an inclined setting relative to the bed support plate 4.

[0047] Further, continue to refer to Figure 1-Figure 3 The smart bed also includes a pad 6, at least part of which is arranged in the area between the first end of the bed support plate 4 toward the back plate 3 and the second end of the back plate 3 toward the bed support plate 4, the upper surface of the pad 6 is lower than the lower surface of the bed support plate 4, and the upper surface of the pad 6 is lower than the second end of the back plate 3 toward the bed support plate 4.

[0048] Specifically, the pad 6 is fixed on the lower surface of the bed support plate 4 by bolts, and is extended toward the back plate 3 along the direction from the bed support plate 4 to the back plate 3, and the pad 6 is directly fitted with the bed support plate 4. When a gap is formed between the back plate 3 and the bed support plate 4, the pad 6 can be used to effectively support the mattress extending from the bed support plate 4 toward the back plate 3, thereby preventing the mattress from being embedded in the gap formed between the back plate 3 and the bed support plate 4.

[0049] Further, continue to refer to Figure 1-Figure 3 An avoidance groove 61 is provided at one end of the pad 6 close to the back plate 3, and the avoidance groove 61 corresponds to at least part of the lifting and translation mechanism 2. When the back plate 3 gradually approaches the bed support plate 4, the lifting and translation mechanism 2 moves toward the bed support plate 4, and the avoidance groove 61 is used to avoid the lifting and translation mechanism 2 to prevent interference and collision.

[0050] Further, continue to refer to Figure 1-Figure 3 , a sandwich plate 62 is sandwiched between the pad plate 6 and the bed support plate 4, so that the upper end surface of the pad plate 6 is lower than the lower surface of the bed support plate 4. Since the back plate 3 moves in a curve, if there is no sandwich plate 62, the front end of the back plate 3 will collide with the pad plate 6, so the sandwich plate 62 can reduce the height of the pad plate 6 to prevent the sandwich plate 62 from contacting the back plate 3. However, the height of the sandwich plate 62 cannot be too low, otherwise it cannot be used to support the mattress that falls into the gap when the back plate 3 is raised and a gap is exposed between the back plate 3 and the bed support plate 4.
