[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 This utility model discloses an electric bed frame, which includes a base frame 1, a movable frame 2, a fixed rod 3, a movable rod 4, and a drive mechanism 5. The movable frame 2 is used to place a movable bed board 6 and drive the movable bed board 6 to move synchronously. The movable frame 2 is rotatably connected to the base frame 1. Both ends of the fixed rod 3 are respectively sleeved on the base frame 1. Both ends of the movable rod 4 are respectively sleeved on the movable frame 2. One end of the drive mechanism 5 is connected to the fixed rod 3, and the other end is connected to the movable rod 4. The drive mechanism 5 is used to drive the movable rod 4 to move relative to the fixed rod 3 so that the movable frame 2 rotates relative to the base frame 1. When the drive mechanism 5 is working, it can drive the movable rod 4 to move relative to the fixed rod 3. Since the movable rod 4 is connected to the movable frame 2 and the fixed rod 3 is connected to the base frame 1, the movement of the movable rod 4 relative to the fixed rod 3 will drive the movable frame 2 to rotate relative to the base frame 1, thereby realizing the posture adjustment of the electric bed frame, such as raising the back or knees at a certain angle to meet the user's needs for a comfortable semi-reclining or semi-sitting posture.

[0023] The electric bed frame disclosed in this embodiment, during installation, has its two ends of the fixed rod 3 fitted onto the corresponding positions of the base frame 1. This fitting method ensures the fixed rod 3 is accurately positioned on the base frame 1, improving the accuracy of the installation position and simplifying the installation process. Similarly, the two ends of the movable rod 4 are designed with fitting structures that adapt to the movable frame 2. During installation, the two ends of the movable rod 4 are fitted onto the corresponding positions of the movable frame 2, allowing the movable rod 4 to be accurately installed on the movable frame 2. Thus, by using a fitting method to install the fixed rod 3 and movable rod 4 onto the base frame 1 and movable frame 2 respectively, this fitting installation method simplifies the assembly process, reduces assembly difficulty, and effectively improves the accuracy of the installation positions of the fixed rod 3 and movable rod 4. This, in turn, improves the assembly accuracy of the drive mechanism 5, ensuring the electric bed frame can accurately adjust its posture and enhancing the user experience.

[0024] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, the movable frame 2 includes two opposing first rods 21, which are used to connect the headboard 61. One end of each of the two first rods 21 is hinged to the base frame 1. The movable rod 4 includes a first movable rod 41, with a first connecting sleeve 413 at each end of the first movable rod 41. The first connecting sleeve 413 is provided with a first connecting groove 414, and the two first connecting sleeves 413 are fitted onto the two first rods 21 one-to-one through the first connecting groove 414. The fixed rod 3 includes a first fixed rod 31, with both ends of the first fixed rod 31 fitted onto the base frame 1. The driving mechanism 5 includes a first driving mechanism 51, with one end of the first driving mechanism 51 connected to the first fixed rod 31 and the other end of the first driving mechanism 51 connected to the first movable rod 41. Thus, by using the installation method of fitting the first connecting sleeve 413 onto the first rod 21, the relative position of the first movable rod 41 and the first rod 21 can be determined more accurately. During the installation process, the size of the first connecting groove 414 is adapted to the first rod 21, which can effectively reduce the positional offset of the components caused by installation errors, simplify the assembly process, and ensure that the connection between the first movable rod 41 and the first rod 21 is stable and the position is accurate, thereby providing a guarantee for the stable operation of the subsequent drive mechanism 5.

[0025] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, a first fixing sleeve 313 is provided at each end of the first fixing rod 31, and the first fixing sleeve 313 is provided with a first fixing groove 314. The two first fixing sleeves 313 are respectively sleeved on the base frame 1 through the first fixing groove 314. Thus, firstly, the installation method of fitting the first fixing sleeve 313 onto the base frame 1 is simple and convenient. During assembly, simply align the first fixing groove 314 of the first fixing sleeve 313 with the corresponding part of the base frame 1 and gently slip it on to complete the connection between the first fixing rod 31 and the base frame 1. No complicated alignment and tightening steps are required, which greatly shortens the assembly time, improves production efficiency, and reduces labor costs. Secondly, the size and shape of the first fixing groove 314 are precisely designed to match the corresponding part of the base frame 1, enabling the first fixing rod 31 to be accurately positioned in the predetermined position on the base frame 1 during installation. This precise installation method effectively avoids the positional deviation of the first fixing rod 31 caused by installation errors, ensuring that the relative position between the first fixing rod 31 and the base frame 1 is accurate, providing a reliable foundation for the subsequent installation and operation of other components such as the drive mechanism 5.

[0026] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, a first mounting block 411 is provided on the first movable rod 41, and a first mounting groove 412 is provided on the first mounting block 411; a second mounting block 311 is provided on the first fixed rod 31, and a second mounting groove 312 is provided on the second mounting block 311; the first driving mechanism 51 includes a first driving member 511 and a first transmission member 512 that are slidably connected to each other; one of the first driving member 511 and the first transmission member 512 is hinged to the first mounting groove 412, and the other is hinged to the second mounting groove 312. This configuration has the following advantages: Firstly, the first movable rod 41 is provided with a first mounting block 411 with a first mounting groove 412, and the first fixed rod 31 is provided with a second mounting block 311 with a second mounting groove 312, providing a precise positioning structure for the installation of the first drive mechanism 51. The first drive member 511 and the first transmission member 512 are respectively hinged to the first mounting groove 412 and the second mounting groove 312. This hinged mounting groove method can ensure that the connection position between the first drive mechanism 51 and the first movable rod 41 and the first fixed rod 31 is accurate, reducing the problem of unstable operation or uneven force of the drive mechanism 5 due to installation deviation, improving the accuracy and reliability of the entire electric bed frame posture adjustment. In addition, the design of the mounting groove makes the connection of the hinge part more stable, which can effectively withstand the various forces and torques generated by the first drive mechanism 51 during operation, avoiding the loosening or falling off of the connection part, and extending the service life of the electric bed frame. Secondly, the first drive mechanism 51 adopts a structure in which a first drive member 511 and a first transmission member 512 are slidably connected to each other. The first transmission member 512 is slidably disposed on the first drive member 511, and the two are respectively hinged to the first mounting groove 412 and the second mounting groove 312. This design allows the first drive mechanism 51 to adjust its motion state more flexibly when driving the first movable rod 41 to move relative to the first fixed rod 31. When the first drive member 511 is working, the first transmission member 512 can slide inside it, thereby realizing a smooth transition of relative motion between the first movable rod 41 and the first fixed rod 31, reducing impact and vibration during the movement process, and improving the stability and comfort of the electric bed frame posture adjustment. The sliding connection method also allows the output force and movement speed of the first drive mechanism 51 to be adjusted according to actual needs, so that the electric bed frame can adapt to different usage scenarios and user needs. For example, when adjusting the angle of the headboard 61, a slow and smooth adjustment can be achieved, avoiding discomfort to the user due to excessively rapid adjustment. Thirdly, the first drive mechanism 51 is installed through the mounting slots on the first mounting block 411 and the second mounting block 311, which simplifies the assembly process. During assembly, the first drive component 511 and the first transmission component 512 are simply hinged to their respective mounting slots to complete the installation, eliminating the need for complex alignment and fastening operations, thus improving assembly efficiency and reducing labor costs. When the first drive mechanism 51 needs maintenance or replacement, this installation method also makes disassembly more convenient. Simply disconnect the hinged connection to remove the first drive mechanism 51 from the first movable rod 41 and the first fixed rod 31, facilitating its inspection, repair, or replacement, thereby improving the maintainability of the electric bed frame.

[0027] like Figure 5 and Figure 6 As shown, in one embodiment, the first connecting sleeve 413 is provided with a first fastening hole 415, the first rod 21 is provided with a second fastening hole 211, and the electric bed frame also includes a first fastener 8, which is connected to the first fastening hole 415 and the second fastening hole 211. Thus, the first connecting sleeve 413 is provided with a first fastening hole 415, and the first rod 21 is provided with a second fastening hole 211. The two fastening holes are connected by a first fastener 8, which further strengthens the connection between the first connecting sleeve 413 and the first rod 21 on the basis of the original sleeve connection. Although the sleeve connection can provide a certain positioning and initial fixation, the electric bed frame may be subjected to various external forces during long-term use, such as vibration and tension generated by the user turning over or adjusting posture. The presence of the first fastener 8 can effectively resist these external forces, prevent loosening or relative displacement between the first connecting sleeve 413 and the first rod 21, and ensure that the first movable rod 41 and the first rod 21 always maintain a stable and reliable connection, thereby ensuring the stability of the entire electric bed frame structure. Moreover, this dual connection method greatly improves the strength and reliability of the connection, reduces the risk of electric bed frame failure due to loose connection, and extends the service life of the electric bed frame.

[0028] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, the movable frame 2 includes two opposing second rods 22, which are used to connect the leg bed board 63. One end of each of the two second rods 22 is hinged to the base frame 1. The movable rod 4 includes a second movable rod 42, and a second connecting sleeve 423 is provided at each end of the second movable rod 42. The second connecting sleeve 423 is provided with a second connecting groove 424, and the two second connecting sleeves 423 are fitted onto the two second rods 22 one by one through the second connecting groove 424. The fixed rod 3 includes a second fixed rod 32, and both ends of the second fixed rod 32 are fitted onto the base frame 1. The driving mechanism 5 includes a second driving mechanism 52, one end of the second driving mechanism 52 is connected to the second fixed rod 32, and the other end of the second driving mechanism 52 is connected to the second movable rod 42. Thus, firstly, the installation method of fitting the second connecting sleeve 423 onto the second rod 22 and the second fixing rod 32 onto the base frame 1 greatly simplifies the assembly process. During assembly, only the second connecting sleeve 423 needs to be fitted onto the second rod 22 and the second fixing rod 32 onto the base frame 1 to complete the initial installation, reducing the skill requirements for assembly personnel and facilitating the large-scale production of the electric bed frame. Secondly, the second connecting sleeve 423 is connected to the second rod 22 through the second connecting groove 424. This connection method ensures that the installation position between the second movable rod 42 and the second rod 22 is accurate. The size and shape of the second connecting groove 424 are carefully designed to fit tightly with the second rod 22, reducing errors during installation and ensuring the accurate installation of the second movable rod 42. The lever 42 can stably run along the predetermined trajectory during the movement; thirdly, due to the precision of the installation position between the second movable lever 42 and the second rod 22, and between the second fixed lever 32 and the base frame 1, the second drive mechanism 52 can more efficiently exert its driving function after being connected to the second fixed lever 32 and the second movable lever 42. When the second drive mechanism 52 drives the second movable lever 42 to move relative to the second fixed lever 32, it can do so with predetermined force and speed, reducing energy loss and unnecessary vibration, improving the working efficiency of the drive mechanism 5. Furthermore, the accurate installation position and stable connection relationship also make the second drive mechanism 52 less affected by interference during operation, extending the service life of the drive mechanism 5 and reducing the failure rate of the electric bed frame.

[0029] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, a second fixing sleeve 323 is provided at each end of the second fixing rod 32. The second fixing sleeve 323 is provided with a second fixing groove 324, and the two second fixing sleeves 323 are respectively fitted onto the base frame 1 through the second fixing grooves 324. Thus, during assembly, the second fixing sleeves 323 with second fixing grooves 324 at both ends of the second fixing rod 32 only need to be aligned with the corresponding parts of the base frame 1 by the second fixing grooves 324 of the second fixing sleeves 323, and then gently fitted to complete the connection between the second fixing rod 32 and the base frame 1. There is no need for complicated alignment and fastening steps, which greatly shortens the assembly time, improves production efficiency, and reduces labor costs. Furthermore, the connection between the second fixing sleeve and the base frame 1 through the second fixing grooves 324 enables precise positioning and installation. The size and shape of the second fixing grooves 324 are precisely designed to match the corresponding parts of the base frame 1. During the installation process, the second fixing rod 32 can be quickly and accurately positioned in the predetermined position on the base frame 1, avoiding the positional deviation of the second fixing rod 32 due to installation errors.

[0030] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, the second movable rod 42 is provided with a third mounting block 421, and the third mounting block 421 is provided with a third mounting groove 422; the second fixed rod 32 is provided with a fourth mounting block 321, and the fourth mounting block 321 is provided with a fourth mounting groove 322; the second driving mechanism 52 includes a second driving member 521 and a second transmission member 522 that are slidably connected to each other; one of the second driving member 521 and the second transmission member 522 is hinged to the second mounting groove 312, and the other is hinged to the fourth mounting groove 322. This configuration offers several advantages. First, by providing a third mounting block 421 and a third mounting slot 422 on the second movable rod 42, and a fourth mounting block 321 and a fourth mounting slot 322 on the second fixed rod 32, a reasonable and compact spatial layout is provided for the installation of the second drive mechanism 52. This design fully utilizes the structural characteristics of the second movable rod 42 and the second fixed rod 32, cleverly integrating the second drive mechanism 52 inside the electric bed frame, avoiding excessive external space occupation, and making the overall structure of the electric bed frame more compact and aesthetically pleasing. Simultaneously, the reasonable structural layout also helps reduce interference between components, ensuring that the second drive mechanism 52 can smoothly extend and retract during operation, thereby improving the working efficiency and reliability of the electric bed frame. Secondly, the third mounting slot 422 and the fourth mounting slot 322 provide a stable mounting position for the hinge of the second drive component 521 and the second transmission component 522. The design of the mounting slots can precisely limit the position and range of motion of the hinge point, preventing the second drive mechanism 52 from shaking or shifting during operation, and ensuring the stability of the connection between the second drive mechanism 52 and the second movable rod 42 and the second fixed rod 32. At the same time, the stable mounting connection helps to reduce noise and vibration caused by loose or shaking components, improves the smoothness and quietness of the electric bed frame operation, and provides users with a more comfortable operating environment. In addition, the stable connection can also reduce wear between components and extend the service life of the electric bed frame. Thirdly, the second drive mechanism 52 consists of a second drive member 521 and a second transmission member 522 that are slidably connected to each other. Both are hinged to the third mounting slot 422 of the second movable rod 42 and the fourth mounting slot 322 of the second fixed rod 32, respectively. This design allows the second drive mechanism 52 to flexibly extend and retract according to the adjustment requirements of the leg bed 63. When it is necessary to adjust the angle of the leg bed 63, the second drive member 521 and the second transmission member 522 slide relative to each other, and push or pull the second movable rod 42 through the hinge point, thereby driving the second rod 22 connected to the second movable rod 42 to rotate around the base frame 1, so as to achieve precise adjustment of the angle of the leg bed 63. Whether it is a small angle adjustment or a large change in posture, it can be accurately achieved through the flexible movement of the second drive mechanism 52, meeting the diverse needs of users for leg support in different usage scenarios.

[0031] like Figure 5and Figure 6 As shown, in one embodiment, the second connecting sleeve 423 is provided with a third fastening hole 425, the second rod 22 is provided with a fourth fastening hole 221, and the electric bed frame also includes a second fastener 9, which is connected to the third fastening hole 425 and the fourth fastening hole 221. Thus, the second connecting sleeve 423 and the second rod 22 are initially connected by a sleeve, but relying solely on this method may lead to loosening during long-term use due to the various forces (such as pressure, tension, and torsional forces) generated by frequent user activities (like turning over or sitting up) on the electric bed frame. By providing the third fastening hole 425 and the fourth fastening hole 221, and using the second fastener 9 for connection, the connection between the two is further strengthened on the basis of the sleeve. This dual connection method greatly improves the strength and reliability of the connection, effectively preventing relative displacement or separation between the second connecting sleeve 423 and the second rod 22 under force, ensuring that the relevant components remain stably connected during the posture adjustment of the electric bed frame, guaranteeing user safety during use, and reducing the risk of accidents caused by loose connections.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the movable frame 2 includes two opposing third rods 23 and two opposing fourth rods 24. The third rods 23 are used to connect the footrest 64, and one end of each of the two third rods 23 is hinged to one of the two second rods 22. One end of each of the two fourth rods 24 is hinged to the base frame 1, and the other end of each of the two fourth rods 24 is hinged to the side of each of the two third rods 23 away from the second rods 22. With this configuration, firstly, this structure allows the footrest 64 to move in tandem with the legrest 63 during adjustment, and it can also adjust its own angle. When the legrest 63 moves under the action of the second drive mechanism 52, the second rods 22 drive the third rods 23 to move. Simultaneously, the fourth rods 24 provide support and guidance between the base frame 1 and the third rods 23, enabling the footrest 64 to adjust according to a predetermined trajectory and angle, achieving multi-dimensional coordinated movement, meeting the diverse needs of users for foot support, and improving user comfort. Secondly, the two opposing third rods 23 and fourth rods 24 together form the support structure of the footboard 64, increasing the stability and load-bearing capacity of the structure. The hinged connection between the third rod 23 and the second rod 22, and between the fourth rod 24 and the base frame 1 and the third rod 23, allows the entire structure to distribute stress evenly when under load, avoiding structural damage caused by local stress concentration. This stable structure can withstand various forces applied by the user on the footboard 64, such as the pressure generated by turning over or sitting up, ensuring that the footboard 64 remains stable during long-term use without shaking or deformation, thus improving the safety and reliability of the electric bed frame.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the base frame 1 includes an upper frame 11 and a lower frame 12 connected vertically. A first rod 21 and a second rod 22 are respectively hinged to both ends of the upper frame 11. The two ends of a first fixing rod 31 are respectively sleeved on the lower frame 12, and the two ends of a second fixing rod 32 are respectively sleeved on the upper frame 11. Thus, the base frame 1 is composed of the upper frame 11 and the lower frame 12 connected vertically, and this layered structure makes the layout of the entire electric bed frame more reasonable. The first rod 21 and the second rod 22 are respectively hinged to both ends of the upper frame 11, providing stable support and rotation points for the movement of the movable frame 2. The two ends of the first fixing rod 31 are sleeved on the lower frame 12, and the two ends of the second fixing rod 32 are sleeved on the upper frame 11. Through the connection between the upper and lower frames 12 and different rods, an interconnected and stable support system is formed. This structure effectively disperses various forces experienced by the electric bed frame during use, such as the user's body weight and impact forces generated during activity, reducing localized stress concentration and thus enhancing the overall stability of the bed frame. It also reduces the risk of shaking or damage caused by structural instability, providing users with a safer and more comfortable experience.
