Description

Technical Field

[0001] This utility model relates to an electric bed, and more specifically to a detachable electric bed. Background Technology

[0002] With the improvement of people's living standards, electric beds have become widely used. A typical electric bed structure includes a reversible bed board, a bed frame, and a drive motor, especially a push-rod motor. The bed board consists of multiple hinged panels. The drive motor is hinged to the bed frame, and by extending or retracting the motor's drive rod, it raises or lowers the bed board. Furthermore, multiple motors can be used to independently raise or lower the head, hips, or feet of the bed board, meeting the needs of changing positions while lying in bed.

[0003] In the existing technology, the bed frame of an electric bed is generally a one-piece structure, with the various components of the bed frame fixed together by welding, and the bed frame cannot be disassembled. Although this type of bed frame structure has good stability, it is very inconvenient to transport. Due to the large size of the bed frame, the inability to disassemble it results in the bed frame occupying a lot of space, increasing transportation costs. In addition, when the user's room door is small, the bed frame may not be able to fit into the room or may be difficult to fit in. Therefore, the one-piece bed frame has many inconveniences in use.

[0004] While some electric bed frames are detachable, the disassembled parts are still quite long, making them inconvenient to store or move. Fully detachable bed frames, on the other hand, have scattered parts, and the overall disassembly and assembly structure, including the bed frame and bed board, is complex, causing significant inconvenience. Furthermore, some existing electric beds have footrests installed on the footboard at the rear or headboard at the front, serving as supports or stops. However, these footrests are usually fixed to the footboard, making them difficult to disassemble and hindering the bed frame's storage. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable electric bed, which can be easily disassembled and assembled, and the disassembled electric bed can be easily packaged, handled and transported.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A detachable electric bed includes a bed frame mounted on a bed frame, the bed frame being divided into a left bed frame and a right bed frame. The left bed frame includes a hinged first bed frame and a second bed frame, and the right bed frame includes a sequentially hinged third bed frame, a fourth bed frame, and a fifth bed frame. The bed frame includes a left bed frame and a right bed frame, with the left and right bed frames mounted on the left and right bed frames respectively. The left and right bed frames each include two horizontal bars and two vertical bars forming a rectangular frame. The vertical bars on the inner side of the left and right bed frames are detachably connected, or the inner ends of the horizontal bars on the same side of the left and right bed frames are detachably connected. The bottom of the first and fourth bed frames are respectively equipped with driving devices, each driving device including an electric push rod installed inside the bed frame and a tilting support assembly installed below the bed frame. Each driving device drives the first and fourth bed frames to tilt and lift or flatten.

[0008] Furthermore, the outer sides of the second and third bed frames are hinged ends, and the inner sides of the second and third bed frames are mounted on and detachably connected to the inner longitudinal bars of the left and right bed frames.

[0009] Furthermore, the bottom surfaces of the left and right bed frames form a flat plane.

[0010] Furthermore, the bottom surfaces of the left and right bed frames are detachably connected to bed legs.

[0011] Furthermore, the bed legs include detachably connected upper and lower bed legs, with the upper end of the upper bed leg detachably connected to the bottom surfaces of the left and right bed frames.

[0012] Furthermore, the first, second, third, fourth, and fifth bed frames are either bed boards or bed frames. The bed frame includes a rectangular outer frame with supporting mesh strips connected to its upper plane, and multiple inner support rods connected to the outer frame.

[0013] Furthermore, the inner end of the fifth bed is hinged to the fourth bed, and at least one bed tail frame is detachably connected to the outer end of the fifth bed. The bed tail frame is movably inserted into a positioning hole on the fifth bed and is limited in position during use.

[0014] Furthermore, the end frame of the bed includes vertical poles extending downward from both ends of the horizontal poles. The bottom of the vertical poles extends towards the fourth bed body and has a bottom pole that can fit against the upper surface of the fifth bed body. The free end of the bottom pole extends downward to a post. The outer end of the fifth bed body has a positioning hole corresponding to each post. A positioning buckle is inserted into the positioning hole. After the post is inserted into the positioning buckle, the positioning buckle is limited on the positioning hole, and the post is limited in the direction of the support surface of the fifth bed body.

[0015] Furthermore, the flip support assembly includes a support rod connected to each end of a flip rod. The lower end of the support rod is pivotally connected to the inner side of the crossbar of the left and right bed frames. The upper end of the support rod is connected to a rotatable roller. The two ends of the electric push rod are pivotally connected to a first motor bracket and a second motor bracket, respectively. The first motor bracket is fixed in the flip rod, and the second motor bracket is fixed on the outer longitudinal bar of the left and right bed frames.

[0016] Furthermore, the first and fourth bed frames stand upright towards the center of the bed frame, and the driving devices corresponding to the first and fourth bed frames are in opposite directions; the fifth bed frame tilts up when the fourth bed frame stands up, and at least one support arm is provided on the inner side of the right bed frame, which supports the fifth bed frame when the fourth bed frame drives the fifth bed frame to tilt up.

[0017] With the above structure, the electric bed of this utility model has the following advantages:

[0018] (1) The bed body and bed frame of the electric bed can be separated into two parts, and the bed legs can also be disassembled, which can reduce the space occupied and the packaging volume, making it easier to move and store;

[0019] (2) The bed frame can be laid flat (on the ground) or the bed legs can be optionally assembled, and the height of the bed legs can be changed according to the usage requirements;

[0020] (3) The bed end frame on the bed frame is also detachable and can be disassembled and assembled according to usage needs. It can also be convenient to store the bed frame after disassembly.

[0021] (4) The electric bed is easy to use. The electric push rod drives the flipping rod to rotate, which in turn drives the support rod to lift the bed board or flatten it. It occupies a small volume and is easy to operate. The two ends of the electric push rod are hinged to the first motor bracket and the second motor bracket. The first motor bracket and the second motor bracket also have reinforcing plates on the outside, which makes the pushing and rotating process more stable and extends the service life.

[0040] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0041] Combination Figures 1 to 7As shown in the illustration, this is one embodiment of the present invention. The present invention discloses a detachable electric bed, comprising a bed frame with a bed body mounted on it. In this invention, the bed body is divided into a detachable left bed body a and a right bed body b, allowing the left bed body a and right bed body b to be disassembled into two parts, reducing space occupation and facilitating transport and storage. The left bed body a includes a hinged first bed body 11 and a second bed body 12, and the right bed body b includes a sequentially hinged third bed body 13, a fourth bed body 14, and a fifth bed body 15. The bed frame includes a detachable left bed frame (c) and a right bed frame (d). Left bed body (a) and right bed body (b) are respectively mounted on left bed frame (c) and right bed frame (d). Left bed frame (c) and right bed frame (d) each include two horizontal bars (21) and two vertical bars (22) forming a rectangular frame. The inner vertical bars (22) of left bed frame (c) and right bed frame (d) are detachably connected, or the inner ends of the horizontal bars (21) on the same side of left bed frame (c) and right bed frame (d) are detachably connected. This allows left bed frame (c) and right bed frame (d) to be disassembled into two parts, reducing space occupation and facilitating transportation and storage. In this example, the inner ends of the horizontal bars (21) on the same side of left bed frame (c) and right bed frame (d) are detachably connected. Figure 4 As shown, a first connecting piece 23 can be provided extending from the inner end of the crossbar 21 towards the inner side of the bed body. When the inner ends of the two crossbars 21 on the same side are joined together, the corresponding two first connecting pieces 23 can abut against each other. Each first connecting piece 23 has a screw hole. After a bolt 24 is passed through the screw holes on both first connecting pieces 23 simultaneously, and then locked with a nut, the two crossbars 21 can be detachably connected in the middle of the bed frame. Of course, holes (screw holes) can also be directly drilled on the sides of the two longitudinal bars 22, and then bolts and nuts can be passed through the corresponding holes (screw holes) on the two longitudinal bars 22 to achieve a detachable connection. Furthermore, the two longitudinal bars 22 can also be connected by at least one connecting rod (the connecting rod is located at the bottom between the two longitudinal bars, and the two ends of the longitudinal bars are detachably connected to the connecting rod by bolts and nuts).

[0042] In this embodiment, the outer edges of the second bed body 12 and the third bed body 13 are hinged ends. The inner edges of the second bed body 12 and the third bed body 13 are mounted on the inner longitudinal rods 22 of the left bed frame c and the right bed frame d, specifically the inner edges 121 and 131 of the second bed body in this embodiment. Furthermore, the inner edges of the second bed body 12 and the third bed body 13 can be mounted on and detachably connected to the inner longitudinal rods 22 of the left bed frame c and the right bed frame d, allowing the bed body to be fixed to the bed frame and preventing detachment. In this embodiment, screw holes (not shown in the figure) can be provided on the bottom surface of the inner edges 121 and 131 of the second bed body, and corresponding screw holes are also provided in the inner longitudinal rods 22 of the left bed frame c and the right bed frame d. Bolts are then passed from bottom to top through the screw holes in the longitudinal rods and then through the screw holes on the inner edges of the second bed body 12 and the third bed body 13 for screw-on fixation. In this embodiment, the inner longitudinal bars 22 of the left bed frame c and the right bed frame d are mounted above the two crossbars 21. Therefore, multiple support blocks 25 for the left bed body a and the right bed body b can be protruded on the crossbars 21 and the outer longitudinal bars 22. Furthermore, support plates 26 can be welded to the crossbars 21. The support plates 26 are provided with connecting holes. The second bed body 12 and the third bed body 13 can be provided with support plate connecting holes 17. The second bed body 12 and the third bed body 13 can be fixed to the support plates 26 by adding bolts, making the bed body more firmly fixed.

[0043] The first bed frame 11 can serve as a backrest, the fourth bed frame 14 as a leg support, and the fifth bed frame 15 as a foot support. The second and third bed frames 12 and 13, located in the middle of the bed, can serve as lumbar supports. The first, second, third, fourth, and fifth bed frames 11 and 15 can each be either bed boards or bed frames. In this embodiment, all are bed frames. Each bed frame includes a supporting mesh connected to the upper plane of a rectangular outer frame. The mesh support reduces the bed's weight, and the mesh structure, relative to the bed board, allows for clearance from the driving components (electric push rods and motors) below, reducing the overall height of the bed frame. Multiple inner support rods 16 are also connected within the outer frame. These inner support rods can be formed in an H-shape within the bed frame, making the bed frame more stable. The inner support rods 16 can be supported on the crossbars 21 and the protruding support blocks 25 on the outer longitudinal bars 22. Furthermore, a tubular groove segment 18 can be formed in the frame members or inner support rods of the bed frame corresponding to some of the bed bodies (in this example, the tubular groove segment 18 is provided on the frame members of the fourth bed body 14 and the fifth bed body 15), and reinforced with sheet metal. The groove formed on the bottom surface of the tubular groove segment 18 provides clearance for the electric push rod 41. By forming a certain clearance space, the electric push rod 41 can achieve extension and retraction more smoothly, and the cooperation structure between it and the bed body is more compact.

[0044] To enable the sections of the bed board that support the head, back, and legs of the human body to be raised and lowered, the bottom of the first bed frame 11 and the fourth bed frame 14 are respectively equipped with driving devices. The driving devices include an electric push rod 41 installed inside the bed frame and a tilting support assembly installed under the bed frame. Each driving device drives the first bed frame 11 and the fourth bed frame 14 to tilt and raise or lower. The tilting support assembly includes a support rod 32 connected to each end of a tilting rod 31. The support rods 32 at both ends of the tilting rod 31 are symmetrical. The lower ends of the support rods 32 are pivotally connected to both sides of the bed frame, so that the lower ends of the support rods 32 are pivotally connected to the inner side of the crossbar 21 of the left bed frame c and the right bed frame d. Rotatable rollers 33 are connected to the upper ends of the support rods 32. The two ends of the electric push rod 41 are pivotally connected to the first motor bracket 42 and the second motor bracket 43, respectively. The first motor bracket 42 is fixed in the flip rod 31, and the second motor bracket 43 is fixed to the rod of the bed frame. In this embodiment, the second motor bracket 43 is fixed to the longitudinal rod 22 located on the outer side of the left bed frame c and the right bed frame d. The electric push rod 41 pushes the first motor bracket 42 to drive the flip rod 31 to rotate. The flip rod 31 drives the support rod 32 to rotate to lift the first bed body 11 and the fourth bed body 14, which are then tilted for support or lowered to be flat. The rollers 33 on the support rod 32 support the bottom surfaces of the first bed body 11 and the fourth bed body 14, and can slide on the bottom surfaces of the first bed body 11 (which serves as the backrest) and the fourth bed body 14 (which serves as the legrest) during lifting and lowering. To facilitate the sliding of the roller 33, the bottom surfaces of the first bed 11 and the fourth bed 14 are also provided with strip-shaped slide rails 34 corresponding to the moving trajectory of the roller 33, allowing the roller 33 to roll along the slide rails 34. In this embodiment, the slide rails 34 are mounted on the inner support rods 16 of the bed frame where the first bed 11 and the fourth bed 14 are located. The slide rails can form U-shaped grooves to prevent the roller 33 from shifting and to increase strength to prevent the slide rails 34 from bending and deforming.

[0045] Furthermore, in this invention, the first motor bracket 42 and the second motor bracket 43 respectively extend reinforcing plates that can be fixed to the flip rod 31 and the bed frame rod (outer longitudinal rod 22). In this embodiment, the first motor bracket 42 includes side first connecting pieces 422 extending on both sides of a first connecting groove block 421 located in the middle, so that the portion of the first connecting groove block 421 that contacts the flip rod 31 and the first side connecting pieces 422 can be connected or welded to the flip rod 31; the second motor bracket 43 includes second side connecting pieces 432 extending on both sides of a second connecting groove block 431, so that the portion of the first connecting groove block 431 that contacts the longitudinal rod 22 and the second side connecting pieces 432 can be connected or welded to the outer longitudinal rod 22 in the left bed frame c and the right bed frame d. The two first side connecting pieces 422 form the reinforcing plates of the first motor bracket 42, and the two second side connecting pieces 432 form the reinforcing plates of the second motor bracket 43. By adding a reinforcing plate to the first or second motor bracket, the connection area is increased and the rigidity is improved. This disperses the force on both ends of the electric push rod at the connection point on the first motor bracket 42 or the second motor bracket 43, so that the force on the electric push rod 41 is not too concentrated, thus better protecting the electric push rod and the motor, and making the movement process more stable.

[0046] Combination Figure 2 , Figure 4 As shown, in the drive device where the first bed 11 is located, the middle part of the support rod 32 protrudes towards the bottom surface of the first bed 11 to form a bend, and the middle part of the support rod 32 protrudes towards the bottom surface of the back plate at an obtuse angle. A roller 33 is connected to the upper end of the support rod 32, and an auxiliary roller 35 with the same structure as the roller 33 is connected to the protruding part of the middle part of the support rod 32. The auxiliary roller 35 can overcome the resistance of the first bed 11 when it is flipped (especially when it is flipped to a certain angle). The auxiliary roller 35 is first attached to the first bed 11 to lift it smoothly. Then, after it is pushed up to a certain height, the roller 33 is switched to be attached to the bottom surface of the back plate. Since the distance between the auxiliary roller 35 and the rotating shaft (the pivot point at the bottom of the support rod 32) is smaller than that of the roller 33, the torque of the auxiliary roller 35 is smaller (according to the torque formula M=F*L), which saves more effort and makes it easier to lift, thereby ensuring the smoothness and stability of the first bed 11 during the lifting process.

[0047] like Figure 3 , Figure 4As shown, the fifth bed frame 15 tilts up when the fourth bed frame 14 is raised. At least one support arm 36 is provided on the inner side of the bed frame, supporting the fifth bed frame 15 (foot bed frame) when the fourth bed frame 14 (leg bed frame) tilts it up. In this embodiment, a support arm 36 is connected to each side of the bottom of the fifth bed frame 15, and the two support arms 36 are symmetrical. The two ends of the support arms 36 are pivotally connected to the bottom surface of the fifth bed frame 15 and the inner side of the crossbar 11 in the bed frame, respectively. In this embodiment, the upper end of the support arm 36 is pivotally connected to the bottom surface of the fifth bed frame 15 (pivotibly connected to the side wall of an inner support rod in the fifth bed frame 15). When the right bed frame b separates from the right bed frame d, the upper end of the support arm 36 is disconnected from the fifth bed frame 15. In addition, during bed board adjustment, for example when it is necessary to lift the back and leg sections of the bed, the first bed 11 and the fourth bed 14 stand up towards the center of the bed frame, and the drive devices corresponding to the first bed 11 and the fourth bed 14 are in opposite directions.

[0048] The bottom surfaces of the left bed frame c and the right bed frame d can be made to form a plane, that is, in the frame formed by the combination of the horizontal bar 21 and the vertical bar 22, the bottom surface forms a supporting plane, which allows the bed frame to be placed directly on a flat surface (such as the ground) without the bed legs, making it more convenient to use.

[0049] The bottom surfaces of the left bed frame c and the right bed frame d can be detachably connected to bed legs 5. Bed legs 5 can be connected to the sides and center of the bed frame respectively. In this embodiment, the bed legs 5 consist of an upper bed leg 51 and a lower bed leg 52 that are detachably connected and assembled vertically. The upper end of the upper bed leg 51 is detachably connected to the bottom surfaces of the left bed frame c and the right bed frame d. The upper bed leg 51 and the lower bed leg 52 can be connected by threads. A first screw section 521 is provided at the top of the lower bed leg 52, which can be screwed into the threaded hole at the bottom of the upper bed leg (not shown in the figure), thereby allowing the height of the bed legs 5 to be adjusted according to usage requirements. A second screw section 511 is provided at the top of the upper bed leg 51, which can be screwed into the threaded hole at the bottom surface of the left bed frame c and the right bed frame d, realizing the detachable connection of the bed legs. In this embodiment, a screw hole can be provided on the bottom surface of the first connecting piece 23 at the inner end of the crossbar 21 in the middle of the bed frame. The second screw section 511 on the upper bed leg 51 can be threaded into the first connecting piece 23, thereby connecting the bed leg 5 to the middle of the bed frame. For the sides or other positions of the bed frame, screw holes can be provided on the bottom surface of the crossbar 21 in the left bed frame c or the bottom surface of the longitudinal bar 22 located on the outer side, for the bed leg 5 to be screwed on.

[0050] The inner end of the fifth bed body 15 is hinged to the fourth bed body 14. Furthermore, at least one bed end frame 6 is detachably connected to the outer end of the fifth bed body 15 as a bed end stop. The bed end frame 6 is movably inserted into the positioning hole 151 on the fifth bed body 15 and is limited in use. Depending on the length of the bed end frame 6, one, two, or more bed end frames 6 can be provided at the outer end of the fifth bed body 15. The bed end frame 6 may include vertical poles 62 extending downward from both ends of a horizontal bar 61. The bottom of the vertical pole 62 extends towards the fourth bed body 14 and has a bottom pole 63 that can fit against the upper surface of the fifth bed body 15. The horizontal bar 61 and the vertical pole 62 form a U-shaped frame that supports the outer side of the fifth bed body 15. The free end of the bottom pole 63 extends downward to a post 64. The outer end of the fifth bed body 15 has a positioning hole 151 corresponding to each post. A positioning buckle 65 is inserted into the positioning hole 151. After the post 64 is inserted into the positioning buckle 65, the positioning buckle 65 is limited to the positioning hole 151, and the post 64 is limited in the direction of the support surface of the fifth bed body 15. The bottom of the insertion post 64 can be cone-shaped. The positioning buckle 65 includes a cap 651 and insertion feet. The positioning buckle 65 has a through hole 650 in the middle for the insertion post 64 to be inserted vertically. The insertion feet can form two cantilevered half-insertion feet 652. The cap 651 is limited at the top of the positioning hole 151. There is an opening and closing gap between the two half-insertion feet 652, and a stop hook block 653 extends outward from the bottom of the half-insertion feet. The through hole 650 can be made larger at the top and smaller at the bottom (for example, the diameter of the upper part is slightly larger than that of the insertion post 64, and the diameter of the lower part is slightly smaller than that of the insertion post 64), so that when the insertion post 64 is inserted into the through hole 650, the positioning buckle 65 can be gradually opened and pre-tightened to prevent loosening. When the insertion post 64 is inserted into the positioning buckle 65, the two half-insertion feet 652 are opened, and the insertion post 64 can be clamped in the positioning buckle 65. The stop hook block 653 can limit and stop at the bottom of the positioning hole 151. When the footboard 6 is in use, the horizontal bar 61 is subjected to a horizontal outward pushing force. At this time, the insert 64 is inserted into the positioning buckle 65, which can limit the footboard 6 and prevent it from being pushed over or easily lifted during use. When the electric bed frame is disassembled, the insert 64 can be pulled out from the positioning buckle 65 by applying upward force, so that the footboard 6 can be installed or removed according to usage needs, which is flexible and easy to store when the bed frame is disassembled.

[0051] When using the bed frame of this utility model, the bed body can be disassembled into two parts: the left bed body and the right bed body. The bed frame can also be disassembled into two parts: the left bed frame and the right bed frame. The bed legs can also be disassembled and the height can be adjusted according to usage needs. The bed tail frame on the bed body is also detachable. With simple operation (disconnecting some threaded connections and the connection between bolts and nuts), the electric bed can be disassembled into a smaller volume. It is also easy to assemble, thereby reducing the space occupied and packaging volume, and making it easy to transport and store.

[0052] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
