Therefore, the following detailed implementation manners and the accompanying drawings are only illustrative descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0019] Embodiment 1: The device mainly includes a mattress 1, a bottom plate 2, a mounting plate 10, a second rotating column 12, a first limiting sliding plate 13, a first fixing plate 14, a second fixing plate 24, a threaded rod 25, and a first motor 26.

[0020] Focus on referring to Figure 1 , Figure 2 , Figure 3, the mattress 1 has a certain softness like the existing sofa cushions. Iron plates are provided on both the front and back sides of its two sides, so as to facilitate the limited rotation of the first rotating column 4 thereon. This technology is obvious in this field and will not be elaborated. A plurality of mattresses 1 are arranged in parallel from left to right. First rotating columns 4 are fixedly connected to both the front and back sides of the two sides of the plurality of mattresses 1. Two first rotating columns 4 on the right side of the left mattress 1 and two first rotating columns 4 on the left side of the right mattress 1 are respectively jointly and rotationally connected with a first connecting plate 5 in a limited manner, so that two adjacent mattresses 1 are hinged together.

[0021] Key reference Figure 3 and Figure 8 , a plurality of telescopic columns 6 are fixedly connected to the bottom of each mattress 1. The plurality of telescopic columns 6 are evenly distributed at the bottom of the mattress 1. The bottom of the telescopic column 6 is slidably connected to the first sliding sleeve 7 in a limited manner. A second elastic member 35 is fixedly connected between the inner bottom of the first sliding sleeve 7 and the bottom of the telescopic column 6.

[0022] Key reference Figure 3 , the bottoms of the plurality of first sliding sleeves 7 are fixedly connected together with a mounting plate 10.

[0023] Key reference Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 , both sides of the top of the threaded rod 25 are fixedly connected with fourth limiting sliding plates 23. The tops of the two fourth limiting sliding plates 23 are fixedly connected together with a second fixing plate 24. Both sides of the top of the second fixing plate 24 are fixedly connected with fifth connecting plates 18. The tops of the two fifth connecting plates 18 are fixedly connected together with a first fixing plate 14. The threaded rod 25 is rotationally connected between the second fixing plate 24 and the first fixing plate 14 in a limited manner. A third limiting sliding plate 19 is threadedly connected to the outer wall of the threaded rod 25. Both sides of the top of the third limiting sliding plate 19 are fixedly connected with first limiting sliding plates 13. The two first limiting sliding plates 13 are slidably connected to the first fixing plate 14 in an up-and-down limiting manner. The two first limiting sliding plates 13 are jointly and rotationally connected with a second rotating column 12. Both sides of the second rotating column 12 are fixedly connected with second connecting plates 11. The tops of the two second connecting plates 11 are fixedly connected together with a mounting plate 10.

[0024] Key reference Figure 4 , a first motor 26 is fixedly installed at the bottom of the second fixing plate 24. The power output end of the first motor 26 is connected to the threaded rod 25.

[0025] It should be noted that the threaded rod 25 has a relatively long distance. Only the threaded rod 25 is shown in the figure. The relatively long threaded rod 25 can enable the mattress 1 to rise to a relatively high distance, so as to adjust the inclination of the mattress 1, so that the bed composed of a plurality of mattresses 1 can be deformed into a large-scale backrest and a large-scale leg lift.

[0026] Key reference Figure 1 On the top of the bottom plate 2, an auxiliary limiting sliding groove 3 is formed, and the fourth limiting sliding plate 23 is connected to the inside of the auxiliary limiting sliding groove 3 in a left - right limiting sliding manner.

[0027] It should be noted that the fourth limiting sliding plate 23 at the bottom of the middle mattress 1 is fixedly installed in the auxiliary limiting sliding groove 3.

[0028] When the first limiting sliding plate 13 and the second rotating column 12 move upward, at this time, the mattress 1 tilts upward or downward. At this time, the fourth limiting sliding plate 23 is driven to move left and right passively, so that the bed formed by multiple mattresses 1 can lift the head, lift the back or lift the legs, thereby changing the form of the bed body composed of multiple mattresses 1.

[0029] The device is also provided with a controller and a storage battery. A control button is arranged on the controller, and the controller is electrically connected to the second motor 27.

[0030] Embodiment 2: On the basis of Embodiment 1, a technical means is added to enable the fourth limiting sliding plate 23 to slide smoothly.

[0031] Key reference Figure 4 On both sides of the two sixth connecting plates 22, first elastic members 21 are fixedly connected. On the side of the two first elastic members 21 away from the two sixth connecting plates 22, second limiting sliding plates 20 are fixedly connected. The two second limiting sliding plates 20 are connected to the inside of the auxiliary limiting sliding groove 3 in a limiting sliding manner.

[0032] Other structures are the same as those in Embodiment 1.

[0033] Embodiment 3: On the basis of Embodiment 1, a technical means is added to adjust the softness and hardness of the mattress 1.

[0034] Key reference Figure 3 、 Figure 4 On both sides of the bottom of the mattress 1, first matching L - shaped hook plates 8 are fixedly connected. A sliding sleeve plate 9 is sleeved on the outer walls of multiple first sliding sleeves 7. The sliding sleeve plate 9 can slide up and down on the outer walls of the multiple first sliding sleeves 7. On the top of both sides of the sliding sleeve plate 9, second matching L - shaped hook plates 29 are fixedly connected. Under the action of the second elastic member 35, the horizontal plate of the second matching L - shaped hook plate 29 presses on the horizontal plate of the first matching L - shaped hook plate 8.

[0035] Key reference Figure 4 On the mounting plate 10, two notches 28 are formed. The bottom of the sliding sleeve plate 9 is fixedly connected with two third connecting plates 15. The two third connecting plates 15 penetrate through the two notches 28, and the bottoms of the two third connecting plates 15 are fixedly connected with a fourth connecting plate 16 together.

[0036] Key reference Figure 7, a limiting circular sleeve 30 is rotationally connected to the outer wall of the second rotating column 12 in a limiting manner. A plurality of seventh connecting plates 32 are fixedly connected to the outer wall of the limiting circular sleeve 30. One side of each of the plurality of seventh connecting plates 32 away from the limiting circular sleeve 30 is hinged with a hinged rod 17, and one side of each of the plurality of hinged rods 17 away from the seventh connecting plate 32 is hinged to the fourth connecting plate 16.

[0037] Key reference Figure 6 , a third rotating column 33 is rotationally connected between the two first limiting sliding plates 13 in a limiting manner. A second gear 34 is fixedly connected to the outer wall of the third rotating column 33. A first gear 31 is fixedly connected to the outer wall of the limiting circular sleeve 30. The first gear 31 and the second gear 34 are meshed with each other. A second motor 27 is fixedly installed on the first limiting sliding plate 13, and the power output end of the second motor 27 is connected to the third rotating column 33.

[0038] It should be noted that when the second motor 27 loses power, the third rotating column 33 can rotate freely.

[0039] Compared with the traditional hydraulic cylinder that directly installs a driving sliding sleeve plate 9 on the second connecting plate 11 to move up and down, this device reduces the fatigue of the second connecting plate 11 and the loss of the hydraulic cylinder, and improves the service life of the device. That is, the hydraulic oil in the swinging hydraulic cylinder sloshes, and the working service life is reduced. And if a hydraulic cylinder is installed, it can only be installed on the mattress 1, increasing the fatigue of the mattress 1, making the angle adjustment of the mattress 1 not so safe and stable.

[0040] Other structures are the same as those in the second embodiment.

[0041] In this embodiment, when it is necessary to raise the head, the back, and the legs, the first motor 26 is started at this time to raise the corresponding mattress 1. At this time, under the action of the first rotating column 4 and the first connecting plate 5, there is a certain inclination angle between two adjacent mattresses 1. It should be noted that at this time, the fourth limiting sliding plate 23 will only move horizontally left and right, and the wires on the first motor 26 and the second motor 27 will not have large movements. At this time, it can be ensured that the wires on the first motor 26 and the second motor 27 can operate relatively safely and stably.

[0042] When it is necessary to raise the back and legs significantly, the corresponding mattress 1 is raised to a higher position at this time, and at this time, the fourth limiting sliding plate 23 will be moved to the required position passively, so as to stably support the mattress 1.

[0043] For different people, mattresses 1 with different softness and hardness are required. At this time, the second motor 27 is started to make the third rotating column 33 and the second gear 34 rotate. The second gear 34 and the first gear 31 are meshed with each other to make the limiting circular sleeve 30 rotate. Under the action of the seventh connecting plate 32 and the hinged rod 17, the fourth connecting plate 16 is raised to lowered, thereby changing the initial compression degree of the second elastic member 35, making it suitable for a variety of people.

[0044] A person lies on multiple mattresses 1, and different parts of the human body lie on different positions of the mattress 1. At this time, the mattress 1 is adaptively adjusted under the action of the second elastic member 35, so that the person lies relatively comfortably on the multiple mattresses 1.

[0045] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
