[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used to distinguish the description and should not be construed as indicating or implying relative importance.

[0021] Example: like Figure 1-4As shown, this embodiment proposes a bed with adjustable backrest angle in sections, including a bed body 1. A support frame 2 is horizontally fixedly connected to the inner surface of the bed body 1. A controller 3 is installed on the inner surface of the bed body 1. A first bed board frame 4 is fixedly connected to the upper surface of the support frame 2. A mattress 5 is provided on the upper surface of the first bed board frame 4. Two symmetrically arranged second bed board frames 6 are hinged to the front end of the first bed board frame 4 through four hinges. A third bed board frame 7 is hinged to the rear end of the first bed board frame 4 through two hinges. A fourth bed board frame 8 is hinged to the rear end of the third bed board frame 7 through two hinges. Two first U-shaped frames 9 are symmetrically arranged on the inner side of the bed body 1. A first servo motor 10 is fixedly installed on one side surface of the first U-shaped frame 9. A first connecting shaft 11 is fixedly connected to the output end of the first servo motor 10. A first V-shaped plate 12 is fixedly sleeved and connected on the first connecting shaft 11. A first mounting block 13 is fixedly installed on the lower surface of the second bed board frame 6. The ends of the two first V-shaped plates 12 away from the first connecting shaft 11 are respectively hinged to the two first mounting blocks 13. Users connect to controller 3 via Bluetooth through a corresponding APP on their mobile phones. Controller 3 has a built-in voice recognition chip and control chip. When the user issues a voice command, the voice recognition chip receives and parses the command, and transmits the command signal to the control chip. The control chip sends a control signal to the first servo motor 10 or the second servo motor 15 according to the command type. When one of the first servo motors 10 is running, it drives the corresponding first connecting shaft 11 and the first V-shaped plate 12 to rotate. With the help of the corresponding first mounting block 13, a single second bed frame 6 can rotate, thereby adjusting the angle of the single second bed frame 6. When the single second bed frame 6 is tilted, the corresponding part of the mattress 5 will also tilt. Similarly, when the two first servo motors 10 are running synchronously, the angles of the two second bed frames 6 can be adjusted synchronously, causing the corresponding front part of the mattress 5 to rotate and rise. This allows for independent automatic adjustment or synchronous adjustment of the two second bed frames 6, meeting the user's angle adjustment needs in different scenarios and improving the flexibility and comfort of the bed.

[0022] When a person is sleeping at night, the controller 3 will activate the anti-snoring mode. When snoring is detected, it will control the corresponding first servo motor 10 to run, causing part of the mattress 5 to slowly rise 15°, which can effectively alleviate the person's snoring at night.

[0023] like Figure 3As shown, a second U-shaped frame 14 is fixedly connected to the lower surface of the support frame 2. A second servo motor 15 is fixedly connected to one side surface of the second U-shaped frame 14. A second connecting shaft 16 is fixedly connected to the output end of the second servo motor 15. A second V-shaped plate 17 is fixedly sleeved on the second connecting shaft 16. A second mounting block 18 is fixedly connected to the middle of the rear end of the lower surface of the second bed board frame 6. The end of the second V-shaped plate 17 away from the second connecting shaft 16 is hinged to the second mounting block 18. The first servo motor 10 and the second servo motor 15 are both electrically connected to the controller 3. When the second servo motor 15 runs, it drives the second connecting shaft 16 and the second V-shaped plate 17 to rotate. In conjunction with the second mounting block 18, the third bed frame 7 rotates. At this time, the third bed frame 7 and the fourth bed frame 8 appear as an inverted V shape when viewed from the side, thereby adjusting the mattress 5 to the corresponding shape. At this time, the bed is in zero-gravity mode. When a person lies on the mattress 5, it can effectively help the person fall asleep quickly and reduce the time to fall asleep. (The controller 3 controls the first servo motor 10 and the second servo motor 15 using existing mature intelligent control technology. This application has not improved the control method, so the specific control principle will not be described in detail here.)

[0024] like Figure 1 As shown, a headboard 19 with a soft padding is installed at the front end of the bed frame 1. Two support legs are fixedly connected to the bottom of the headboard 19 and the lower surface of the bed frame 1. The four support legs enable the bed frame 1 and the headboard 19 to be a certain distance from the ground.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the second bed frame 6, the third bed frame 7 and the fourth bed frame 8 are all attached to the lower surface of the mattress 5. The mattress 5 is Y-shaped. The two first U-shaped frames 9 are fixedly connected to the support frame 2. The first bed frame 4 is located inside the bed body 1. The second bed frame 6 is located between the first bed frame 4 and the headboard 19.

[0026] like Figure 3 As shown, the end of the first connecting shaft 11 away from the first servo motor 10 is rotatably connected to the first U-shaped frame 9 through the first bearing, and the end of the second connecting shaft 16 away from the second servo motor 15 is rotatably connected to the second U-shaped frame 14 through the second bearing. The first bearing ensures the stability of the first connecting shaft 11 when rotating, and the second bearing ensures the stability of the second connecting shaft 16 when rotating.

[0027] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
