[0042] Embodiment 1

[0043] Please refer to Figures 1 to 6, an embodiment of the present utility model provides an electric bed frame 100, including: a back bed board 1, a waist bed board 2, a leg bed board 3, a back support frame 4, a waist support frame 5, and a leg support frame 6. The back bed board 1, the waist bed board 2, and the leg bed board 3 are sequentially arranged separately. That is, there is no connection between the back bed board 1, the waist bed board 2, and the leg bed board 3. The back bed board 1, the waist bed board 2, and the leg bed board 3 are preferably made of materials with a certain support strength to facilitate placing a mattress 200 thereon. The back support frame 4 is rotatably connected to the back bed board 1 through a first linear motor 7 and is used to push the back bed board 1 to lift and swing. The waist support frame 5 is connected to the waist bed board 2 and is used to support the waist bed board 2; the leg support frame 6 is connected to the leg bed board 3 and is used to support the leg bed board 3. During the back lifting process, the first linear motor 7 pushes the back bed board 1 to lift. Since the first linear motor 7 is rotatably connected to the back bed board 1, and the back bed board 1 is under the heavy pressure of the mattress, the side close to the waist bed board 2 will swing downward. The back lowering process is the opposite and will not be elaborated here.

[0044] Since the back support frame 4 of the electric bed frame 100 is directly rotatably connected to the back bed board 1 through the first linear motor 7, the waist support frame 5 is connected to the waist bed board 2, and the leg support frame 6 is connected to the leg bed board 3; the manufacturing and assembly of the back bed board 1 frame, the waist bed board 2 frame, and the leg bed board 3 frame, as well as the hinge structure, are omitted. Therefore, it has the advantages of relatively few components, relatively simple structure, and low assembly difficulty.

[0045] Optionally, please refer to Figure 3 , Figure 4 and Figure 6, in this embodiment, the back support frame 4 includes a first bottom frame 41 and a first support vertical pipe 42 vertically disposed on the first bottom frame 41. Specifically, the first bottom frame 41 is an I-shaped steel frame structure. Of course, in some other embodiments, the first bottom frame 41 can also be a frame structure as long as it can stably contact the ground and support the bed board and the mattress 200. The first support vertical pipe 42 can be fixed to the first bottom frame 41 by fasteners (not shown in the figure) or welding. The first linear motor 7 is rotatably connected to the bottom of the back bed board 1, and the output end of the first linear motor 7 is disposed in the first support vertical pipe 42 so as to be movable up and down; thus, the lifting or lowering of the back bed board 1 can be realized by the approaching or separating movement of the first linear motor 7 relative to the first support vertical pipe 42. Specifically, the output end of the first linear motor 7 is a lead screw pair, and the lead screw pair includes a lead screw 71 and a nut 72 that are threadedly connected to each other. The lead screw 71 of the lead screw pair is coaxially connected to the output shaft of the first linear motor 7 (not shown in the figure), and the nut 72 of the lead screw pair is fixedly installed in the inner pipe of the first support vertical pipe 42. Thus, when the first linear motor 7 rotates forward or backward, the lead screw 71 can move upward or downward relative to the nut 72, that is, the lead screw 71 can move upward or downward relative to the first support vertical pipe 42, so that the main body of the first linear motor 7 moves up and down relative to the first support vertical pipe 42. Optionally, in order to improve the stability of the electric bed frame 100, in this embodiment, the back support frame 4 is rotatably connected to the back bed board 1 by two first linear motors spaced apart in the width direction of the mattress 200. That is, two first support vertical pipes 42 are spaced apart in the width direction of the mattress 200 on the first bottom frame 41, and each first support vertical pipe 42 is rotatably connected to the back bed board 1 by a first linear motor 7.

[0046] To prevent the back bed board 1 of the electric bed 1000 with the electric bed frame 100 from flipping towards the waist bed board 2 under the action of gravity in the back-lifting posture. Optionally, at the extreme lifting position, the first linear motor 7 restricts the downward swing of the back bed board 1 through an angle limiting structure. To achieve the rotational limit connection between the first linear motor 7 and the back bed board 1, specifically, in this embodiment, a first shaft seat 73 including a first shaft hole c is configured on the main body of the first linear motor 7, and a first rotating shaft 11 matching the first shaft hole c is configured at the bottom of the back bed board 1; the angle limiting structure includes a first angle limiting convex block 731 axially arranged along the inner circumference of the first shaft hole c, and a first angle limiting sector groove a located on the first rotating shaft 11 and cooperating with the first angle limiting convex block 731. In this way, when reaching the extreme position, the first angle limiting convex block 731 in the first shaft seat 73 can limit the continuous rotation of the first rotating shaft 11. Of course, in some other embodiments, the positions of the first rotating shaft 11 and the first shaft seat 73 can also be swapped, that is, the first rotating shaft 11 is configured on the main body of the first linear motor 7, and the first shaft seat 73 is correspondingly configured at the bottom of the back bed board 1, which is not specifically limited here.

[0047] To make the posture adjustment process of the electric bed 1000 smoother, usually the lifting and swinging of the back bed board 1 do not change rapidly, which will give the user an experience of slow response. For this reason, please refer to Figure 3 , in this embodiment, the waist support frame 5 includes a second bottom frame 51, a second support vertical pipe 52 and a second linear motor 8; the second support vertical pipe 52 is vertically arranged on the second bottom frame 51, the second linear motor 8 is fixedly connected to the waist bed board 2, and its output end is movably arranged up and down in the second support vertical pipe 52. Specifically, the structure of the waist support frame 5 is similar to that of the back support frame 4, the only difference being that the second linear motor 8 and the waist bed board 2 are fixedly assembled, so there is no rotational limit structure, so it will not be elaborated here. In this way, while the back bed board 1 is lifted, the second linear motor 8 can lower the waist and hip bed board to enable the user to experience a faster response speed.

[0048] To improve the user experience, please refer to Figure 3, optionally, in this embodiment, the electric bed frame 100 is further provided with a leg lifting function. Specifically, the leg bed board 3 includes a thigh bed board 31 and a calf bed board 32, and the thigh bed board 31 and the calf bed board 32 are hinged to each other. The leg support frame 6 includes a third bottom frame 61, a third support vertical pipe 62, a third linear motor 9, and a bent pull rod 63. The third support vertical pipe 62 is vertically disposed on the third bottom frame 61. The third linear motor 9 is rotatably connected to the bottom of the thigh bed board 31, and its output end is vertically movably disposed within the third support vertical pipe 62. One end of the bent pull rod 63 is hinged to the end of the calf bed board 32 away from the thigh bed board 31, and the other end is hinged to the third bottom frame 61. Specifically, the structure and connection manner of the leg support frame 6 to the bottom of the thigh bed board 31 are similar to those of the back support frame 4 to the back bed board 1, the difference being that the leg support frame 6 further supports the calf bed board 32 through the bent pull rod 63. Thus, when the third linear motor 9 pushes the thigh bed board 31 to lift or lower, the calf bed board 32 can be synchronously driven to lift or lower.

[0049] To achieve the rotational limit connection between the third linear motor 9 and the thigh bed board 31, optionally, please refer to Figure 5 , in this embodiment, a second shaft seat 91 including a second shaft hole d is disposed on the main body of the third linear motor 9, and a second rotating shaft 311 matching the second shaft hole d is disposed at the bottom of the thigh bed board 31; a second angular limit convex block 911 is axially disposed along the inner circumference of the second shaft hole d, and the second rotating shaft 311 has a second angular limit sector groove b cooperating with the second angular limit convex block 911. Since the angular limit structure of the third linear motor 9 and the thigh bed board 31 is the same as that of the first linear motor 7 and the back bed board 1, it will not be elaborated here.

[0050] To make the overall electric bed frame 100 more firm and prevent displacement between the back support frame 4, the waist support frame 5, and the leg support frame 6, optionally, please refer to Figure 3 , in this embodiment, the back support frame 4, the waist support frame 5, and the leg support frame 6 are connected by a connecting rod 10. Specifically, the connecting rod 10 is threadedly fixed to the first support vertical pipe 42 of the back support frame 4, the second support vertical pipe 52 of the waist support frame 5, and the third support vertical pipe 62 of the leg support frame 6 respectively through fasteners.

[0051] Another aspect of the embodiment of the present invention provides an electric bed 1000, including the electric bed frame 100 as described above and a mattress 200 placed on the back bed board 1, the waist bed board 2, and the leg bed board 3. Since the electric bed 1000 has all the structures and connection relationships of the electric bed frame 100, therefore, it has all the advantages of the electric bed frame 100, which will not be elaborated here.

[0052] Embodiment Two

[0053] This embodiment is basically the same as the first embodiment, except for the connection manners of the first linear motor (not shown in the figure), the back support frame (not shown in the figure), and the back bed board (not shown in the figure). In this embodiment, the main body of the first linear motor is fixed on the first support vertical pipe of the back support frame. The cross-section of the inner pipe of the first support vertical pipe matches the outer shape cross-section of the nut of the lead screw pair of the first linear motor. A first connecting vertical rod is fixedly connected to the nut. The first connecting vertical rod can move up and down within the first support vertical pipe along with the up and down movement of the nut. One end of the first connecting vertical rod away from the nut is rotatably connected to the back bed board. In this way, the movement of the output end of the first linear motor relative to the first support vertical pipe to approach or move away can also be achieved, thereby driving the lifting or lowering of the back bed board.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
