Abstract
Description
Technical Field
[0001] This application relates to the technical field of electric beds, and particularly to an electric bed frame. Background Art
[0002] An electric bed (mainly the electric bed frame part) adjusts the angle of the bed body through a driving device to meet the needs of the human body in different postures. Such an electric bed usually includes a frame body and a bed board installed on the frame body. Through the driving device, the positions of multiple components on the bed board can be adjusted to achieve the change of the bed body angle.
[0003] Chinese Invention Publication Specification CN220529648 discloses an electric bed. For example, the bed board part that supports the human head and back of such an electric bed is integrally designed. When sitting, due to the body leaning back, the neck needs to exert additional force to tilt the head forward in order to view books or electronic devices in the hand. Maintaining this posture for a long time will cause neck soreness and there is no effective support from the electric bed. Summary of the Invention
[0004] This application provides an electric bed frame, and the electric bed frame according to this application can overcome at least one or more problems existing in the prior art.
[0005] An electric bed frame includes a bed board assembly, a main frame, a first telescopic assembly, and a second telescopic assembly. Among them, the bed board assembly is successively hinged by a first frame body, a second frame body, a third frame body, a fourth frame body, and a fifth frame body end to end. The bottom of the third frame body is fixedly connected to the middle part of the main frame. The first telescopic assembly and the second telescopic assembly are adjustable in length on their telescopic axes. Two ends of the first telescopic assembly are respectively rotatably connected to the first frame body and the main frame; two ends of the second telescopic assembly are respectively rotatably connected to the fourth frame body and the main frame.
[0006] For the electric bed frame provided by the embodiment of this application, when the first telescopic assembly starts to extend, the first frame body will be lifted upward, the outer end will be upturned, and the inner end will be pressed down. The second frame body is hinged to the first frame body, and the angle between the originally parallel first frame body and the second frame body will become an obtuse angle. When the first telescopic assembly pushes the first frame body to a predetermined height, the inclination angle of the first frame body relative to the horizontal plane will be greater than the inclination angle of the second frame body relative to the horizontal plane. The human head leans on the inclined first frame body, and the back leans on the second frame body. The angles of the two are set non-conventionally parallel, thereby providing more comfortable head support.
[0007] In a possible implementation manner, the first telescopic assembly includes a first hinge seat, a second hinge seat, and a first electric push rod; the second telescopic assembly includes a third hinge seat, a fourth hinge seat, and a second electric push rod;
[0008] The first hinge base is fixedly connected to the back of the first frame body, and the second hinge base is fixedly connected to the first cross beam of the main frame; the piston end and the support end of the first electric push rod are respectively connected to the first hinge base and the second hinge base in a hinged manner;
[0009] The third hinge base is fixedly connected to the back of the fourth frame body, and the fourth hinge base is fixedly connected to the second cross beam of the main frame; the piston end and the support end of the second electric push rod are respectively connected to the third hinge base and the fourth hinge base in a hinged manner.
[0010] In a possible implementation manner, the first cross beam is located below the second frame body; the second cross beam is located below the third frame body.
[0011] In a possible implementation manner, the outer end of the fifth frame body is connected to the main frame through a connecting rod.
[0012] In a possible implementation manner, support bodies are provided on the first frame body, the second frame body, the third frame body, the fourth frame body and the fifth frame body. The support bodies are elastic fabrics, and the extending direction of the support bodies is perpendicular to the connection direction of the bed board assembly.
[0013] In a possible implementation manner, a plurality of main bed legs are provided on the bottom surface of the main frame, and a plurality of auxiliary bed legs are provided on the bottom surface of the third frame body. The bottom surfaces of the main bed legs and the auxiliary bed legs are flush.
[0014] In a possible implementation manner, when the first telescopic assembly and the second telescopic assembly are in a contracted state, the first frame body, the second frame body, the fourth frame body and the fifth frame body all rest on the main frame.
[0015] In a possible implementation manner, when the first telescopic assembly extends and lifts the first frame body, an obtuse angle is formed between the first frame body and the second frame body, and the inclination angle of the first frame body relative to the horizontal plane is greater than the inclination angle of the second frame body relative to the horizontal plane.
[0016] In a possible implementation manner, when the second telescopic rod extends and lifts the fourth frame body, the fifth frame body tilts towards the outer end side due to the constraint of the hinged connecting rod.
[0017] It should be noted that, on the premise that the above various possible implementation manners do not conflict with each other, they can all be combined. Description of the Drawings

[0027] It should be understood that in all the drawings, the same reference numerals represent the same elements. In the drawings, for clarity, the dimensions of some features may be deformed. The terms used in the specification are only for describing specific embodiments and are not intended to limit the present application. All terms used in the specification (including technical terms and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined.

[0028] On the one hand, an embodiment of the present application provides an electric bed frame. Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2The structure of the electric bed frame is shown from different perspectives, including a bed board assembly 10, a main frame 20, a first telescopic assembly 30, and a second telescopic assembly 40. Among them, the bed board assembly 10 is successively hinged end to end by a first frame body 11, a second frame body 12, a third frame body 13, a fourth frame body 14, and a fifth frame body 15. In a traditional electric bed frame body, the first frame body 11 and the second frame body 12 are rigidly connected as a whole. In this application, the bottom of the third frame body 13 is fixedly connected to the middle part of the main frame 20. The first telescopic assembly 30 and the second telescopic assembly 40 are adjustable in length along their telescopic axes. Two ends of the first telescopic assembly 30 are respectively rotatably connected to the first frame body 11 and the main frame 20; two ends of the second telescopic assembly 40 are respectively rotatably connected to the fourth frame body 14 and the main frame 20.
[0029] Please refer to Figure 5 and Figure 6 , Figure 5 and Figure 6 respectively show the structures of the bed board assembly 10 and the main frame 20. Among them, support bodies 16 are provided on the first frame body 11, the second frame body 12, the third frame body 13, the fourth frame body 14, and the fifth frame body 15. The support bodies 16 are made of elastic fabrics, such as elastic mesh fabrics, spandex fabrics, elastic knitted fabrics, etc.; the extending direction of the support bodies 16 is perpendicular to the connecting direction of the bed board assembly 10.
[0030] The first telescopic assembly 30 includes a first hinge seat 31, a second hinge seat 32, and a first electric push rod 33;
[0031] The second telescopic assembly 40 includes a third hinge seat 41, a fourth hinge seat 42, and a second electric push rod 43;
[0032] The first hinge seat 31 is fixedly connected to the back of the first frame body 11, and the second hinge seat 32 is fixedly connected to the first cross beam 22 of the main frame 20; the piston end and the support end of the first electric push rod 33 are respectively connected to the first hinge seat 31 and the second hinge seat 32 in a hinged manner. Preferably, the first cross beam 22 is located below the second frame body 12.
[0033] The third hinge seat 41 is fixedly connected to the back of the fourth frame body 14, and the fourth hinge seat 42 is fixedly connected to the second cross beam 23 of the main frame 20; the piston end and the support end of the second electric push rod 43 are respectively connected to the third hinge seat 41 and the fourth hinge seat 42 in a hinged manner. Preferably, the second cross beam 23 is located below the third frame body 13.
[0034] The outer end of the fifth frame body 15 is connected to the main frame 20 through a connecting rod 24.
[0035] Guardrails 50 for fixing the mattress are assembled on the outer end faces of the first frame body 11 and the outer end of the fifth frame body 15.
[0036] Please refer to Figure 3 andFigure 4 , Figure 3 and Figure 4 show a usage state of the electric bed frame of the present application from different perspectives. A plurality of main bed legs 21 are provided on the bottom surface of the main frame 20, and a plurality of auxiliary bed legs 17 are provided on the bottom surface of the third frame body 13. The bottom surfaces of the main bed legs 21 and the auxiliary bed legs 17 are flush.
[0037] When the first telescopic assembly 30 and the second telescopic assembly 40 are in a contracted state, the first frame body 11, the second frame body 12, the fourth frame body 14, and the fifth frame body 15 all rest on the main frame 20.
[0038] When the first telescopic assembly 30 starts to extend, the first frame body 11 will be lifted upward, with the outer end tilted upward and the inner end pressed downward. Since the first frame body 11 and the second frame body 12 are connected by a hinge, the angle between the originally parallel first frame body 11 and the second frame body 12 will become an obtuse angle. When the first telescopic assembly 30 pushes the first frame body 11 to a predetermined height, the inclination angle of the first frame body 11 relative to the horizontal plane will be greater than the inclination angle of the second frame body 12 relative to the horizontal plane. At this time, the head of the human body leans on the inclined first frame body 11, and the back leans on the second frame body 12. The angles of the two are set non-traditionally parallel, thus providing more comfortable head support.
[0039] When the second telescopic assembly 40 starts to extend, the side of the fourth frame body 14 close to the fifth frame body 15 will tilt upward. Since the outer end of the fifth frame body 15 is restricted by the hinged connecting rod 24, the fifth frame body 15 is inclined, and its outer end is relatively lower. In this way, the thighs of the human body will lean on the fourth frame body 14, and the calves will lean on the inclined fifth frame body 15, thus providing more comfortable support.
[0040] There is a mattress between the human body and the electric bed, and the mattress changes with the change of the electric bed frame.
[0041] Although the exemplary embodiments of the present application have been described, those skilled in the art should understand that various changes and alterations can be made to the exemplary embodiments of the present application without departing from the spirit and scope of the present application in essence. Therefore, all changes and alterations are included within the protection scope of the present application defined by the claims. The present application is defined by the appended claims, and equivalents of these claims are also included.
