In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0054] Please refer to Figures 1 to 13 It should be noted that the diagrams provided in this embodiment only illustrate the basic concept of the utility model in a schematic manner, and only show the components related to the utility model in the drawings, not the number, shape and size of the components when actually implemented. The actual implementation of each component type, quantity and proportion can be arbitrarily changed, and the component layout type can be more complex.

[0055] In the following description, "transverse" means the width direction (left-right direction) of the bed, and "longitudinal" means the length direction of the bed.

[0056] The first aspect of the utility model provides an electric bed frame, as shown in Figure 1 and Figure 2 The electric bed frame includes a bed frame body 10, the bed frame body 10 includes a front bed frame 101, a rear bed frame 102 and a driving device, and the front bed frame 101 and the rear bed frame 102 are hinged, specifically, the front bed frame 101 includes a back support 1011 and a hip front support 1012 hinged to each other, and the rear bed frame 102 includes a hip rear support 1021 and a leg support 1022 hinged to each other, wherein the hip front support 1011 is arranged adjacent to the hip rear support 1021;The driving device includes a first driver 131 and a second driver 132, the first driver 131 is used to drive the back support 1011 to overturn relative to the hip front support 1012, and the second driver 132 is used to drive the leg support 1022 to overturn relative to the hip rear support 1021.

[0057] The beneficial effects of this electric bed frame are as follows: Since the electric bed frame is composed of a front bed frame 101 and a rear bed frame 102 that can be hinged together, during transportation, if... Figure 10 As shown, the front bed frame 101 and rear bed frame 102 of this electric bed frame can be folded together for packaging and transportation, which greatly reduces the overall volume of the electric bed frame, making it easier to pack, stack, and transport. Furthermore, when the front bed frame 101 and rear bed frame 102 are folded, their top surfaces face outwards, protecting the electrical control components such as the drive unit installed on the bottom surface within the internal space formed by the folding of the front and rear bed frames. This prevents the electrical control components from being damaged during transportation. Therefore, this foldable electric bed frame effectively solves the pain points of electric beds in terms of transportation.

[0058] Furthermore, such as Figures 2 to 4 As shown, in this embodiment, the front bed frame 101 further includes a first transverse support seat 111, which is fixedly disposed transversely at the bottom of the hip front support 1012. The rear bed frame 102 further includes a second transverse support seat 112, which is fixedly disposed transversely at the bottom of the hip rear support 1021. The hinge between the front bed frame 101 and the rear bed frame 102 is achieved through the hinge between the first transverse support seat 111 and the second transverse support seat 112. Preferably, multiple support legs 12 are fixedly disposed at the bottom of both the back support 1011 and the leg support 1022. It can be understood that when the front bed frame 101 and the rear bed frame 102 are in a flat state, the lower end of the support leg 12 is at the same level as the bottom surface of the first transverse support seat and the second transverse support seat. In this way, the first transverse support seat 111, the second transverse support seat 112, and the support legs 12 can achieve horizontal support for the bed frame.

[0059] Furthermore, in order to improve the support strength and placement stability of the electric bed frame, as a preferred embodiment, such as... Figure 2As shown, the bed frame body 10 further comprises a longitudinal horizontal base 14 fixedly arranged at the bottom of the first and second transverse support seats 111 and 112, and extending along the length direction of the bed frame body 10, i.e. one end of the longitudinal horizontal base 14 extends below the back support 1011 and the other end of the longitudinal horizontal base 14 extends below the leg support 1022. When the front and rear bed frames 101 and 102 are in the flat state, the lower ends of the plurality of support legs 12 can be supported on the longitudinal horizontal base 14. By arranging the longitudinal horizontal base 14, firstly, the support strength of the bed frame can be further enhanced, and secondly, since the longitudinal horizontal base 14 is fixedly arranged at the bottom of the first and second transverse support seats 111 and 112 and extends to below the back support 1011 and the leg support 1022 at both ends, the longitudinal horizontal base 14 can limit the relative rotation of the front and rear bed frames when the electric bed frame is in use, thereby improving the stability of the electric bed frame in normal use. It can be understood that when packaging and transporting, the longitudinal horizontal base 14 needs to be disassembled from the first and second transverse support seats 111 and 112, and then packaged together with the folded bed frame or packaged separately for transportation.

[0060] As shown in the drawings, Figure 2 In the present embodiment, the longitudinal horizontal base 14 is fixedly connected to the first and second transverse support seats 111 and 112 by screws. In the present embodiment, the longitudinal horizontal base 14 comprises two longitudinally spaced horizontal beams 141, and a transverse horizontal beam 142 is connected between the front and rear ends of the two longitudinal horizontal beams 141, so that the longitudinal horizontal base 14 has a rectangular frame structure, so that the contact area of the longitudinal horizontal base 14 with the ground is larger and the stability of the support is stronger. Preferably, as shown in the drawings, Figure 2 In the present embodiment, the longitudinal horizontal base 14 is provided with two longitudinal horizontal bases 14 arranged in the width direction of the bed frame body 10. Specifically, in the present embodiment, the longitudinal horizontal base 14 is made of steel pipe by welding, which has high strength.

[0061] In order to further enhance the stability of the bed frame body 10 in normal use, preferably, as shown in the drawings, Figure 3As shown in the embodiment, the bottom of the hip front support 1012 and the hip rear support 1021 is detachably connected with a locking piece 15, one end of the locking piece 15 is connected with the hip front support 1012 through a screw, and the other end of the locking piece 15 is connected with the hip rear support 1021 through a screw. Through the arrangement of the locking piece 15, when the electric bed frame is normally used, the locking piece 15 can further limit the relative rotation of the front bed frame 101 and the rear bed frame 102. Of course, it can be understood that when packaging and transporting, the locking piece 15 also needs to be detached from the hip front support 1012 and the hip rear support 1021, and then the locking piece 15 and the folded bed frame are packaged together or separately packaged and transported.

[0062] Further, as shown in the embodiment, Figure 4 In the embodiment, the first transverse support seat 111 includes two spaced apart cross beams 1111, and a plurality of longitudinal beams 1112 are fixedly connected between the two cross beams 1111, and the hip front support 1012 is welded and fixed on the plurality of longitudinal beams 1112. The structure of the second transverse support seat 112 is the same as that of the first transverse support seat 111, and therefore will not be described here.

[0063] As shown in the embodiment, Figures 4 to 6 In the embodiment, a first connecting piece 1110 is fixedly arranged on the first transverse support seat 111, and a second connecting piece 1120 is fixedly arranged on the second transverse support seat 112, the first connecting piece 1110 is provided with a first connecting hole, the second connecting piece 1120 is provided with a second connecting hole, and a hinge rod 16 is arranged in the first connecting hole and the second connecting hole. Specifically, the hinge rod 16 includes a bolt 161, the first end of the bolt 161 is provided with a bolt head 1611, the second end of the bolt 161 is provided with a threaded section, the bolt 161 is arranged in the first connecting hole and the second connecting hole, the second end of the bolt 161 is arranged out of the first connecting hole and the second connecting hole, and a nut 162 is arranged on the threaded section of the second end of the bolt 161. Through this structure design, when the front bed frame 101 and the rear bed frame 102 need to be folded and packaged for transportation, the nut 162 is loosened, so that the first connecting piece 1110 and the second connecting piece 1120 can be rotated around the bolt 161, and then the front bed frame 101 or the rear bed frame 102 can be turned over for folding; when it is not necessary for the front bed frame 101 and the rear bed frame 102 to rotate relatively, i.e. when it is normally used, the nut 162 can be tightened to relatively lock the first connecting piece 1110 and the second connecting piece 1120, so as to further enhance the stability of the electric bed frame when it is normally used.

[0064] Further, in order to make the electric bed frame better adapt to human characteristics and improve the comfort of the electric bed frame when it is used, preferably, Figure 8 and Figure 9As shown, in the embodiment, the leg support 1022 comprises a thigh support 1022a and a calf support 1022b, specifically, the thigh support 1022a of the leg support 1022 is hingedly connected with the rear hip support 1021, the calf support 1022b is also hingedly connected with the thigh support 1022a, and the calf support 1022b is further hingedly connected with one end of a linkage rod 17, the other end of the linkage rod 17 is hingedly connected with the second horizontal support 112, correspondingly, the second driver 132 is connected between the thigh support 1022a and the rear hip support 1021, for driving the thigh support 1022a to flip relative to the rear hip support 1021. Through the structure design, when the second driver 132 drives the thigh support 1022a to flip relative to the rear hip support 1021, the calf support 1022b will rotate relative to the thigh support 1022a, for example, when the second driver 132 drives the thigh support 1022a to flip upward relative to the rear hip support 1021 from the horizontal state, since the calf support 1022b is hingedly connected with the thigh support 1022a, and the calf support 1022b is hingedly connected with the second horizontal support 112 through the linkage rod 17, the calf support 1022b will change the inclination angle relative to the thigh support 1022a correspondingly, and keep the state close to horizontal. Thus, the human joint characteristics can be better adapted, and the user experience can be greatly improved.

Specifically, the first end of the first driver 131 is hingedly connected with the first horizontal support 111 through the first hinge bracket 1311, and the first end of the second driver 132 is hingedly connected with the second horizontal support 112 through the second hinge bracket 1321.

[0066] Further, as shown in Figure 2 and Figure 3As shown, in this embodiment, a controller 100 is fixedly installed at the bottom of the bed frame body 10, and the first driver 131 and the second driver 132 are both electrically connected to the controller 100. With this structural design, the user can send control signals to the controller 100 via a remote control, thereby allowing the controller 100 to individually control the first driver 131 to drive the back support 1011 to flip, or individually control the second driver 132 to drive the thigh support 1022a to flip, or simultaneously control the first driver 131 and the second driver 132 to simultaneously drive the back support 101 and the thigh support 1022a to flip together. The operation is simple and convenient, optimizing the user experience.

[0067] Furthermore, such as Figure 7 As shown, in this embodiment, a plurality of first hinge pieces 1011a are fixedly provided on the back support 1011, and a plurality of second hinge pieces 1012a are fixedly provided on the front hip support 1012. The first hinge pieces 1011a and the second hinge pieces 1012a are hinged together by a hinge shaft 18. Preferably, in order to avoid noise and improve user experience when the back support 1011 is flipped, a bushing 181 is fitted on the hinge shaft 18 in this embodiment, and the bushing 181 is made of plastic. Preferably, the bushing 181 is made of nylon, which has strong wear resistance and a long service life.

[0068] The hinged connection between the hip support 1021 and the thigh support 1022a, and the hinged connection between the thigh support 1022a and the calf support 1022b, are similar to... Figure 7 The hinge method shown is the same, so it will not be described again here.
