Description

Technical Field

[0001] This invention relates to the field of electric bed technology, and in particular to a folding electric bed with synchronous control of lifting and lowering by left and right motors. Background Technology

[0002] The most common type of electric bed on the market is the one with both backrest and legrest lifting functions. These electric beds are usually driven by a push rod for the backrest and a push rod for the legs. These push rods are often installed at the center of the entire bed frame axis. For some large bed frames, when one side is lying down and the other side is not, the bed board will not be able to lift and lower in sync. Moreover, when the bed frame is heavily loaded, the individual push rod will be subjected to a lot of force, which will affect the service life of the entire bed. Summary of the Invention

[0003] The purpose of this invention is to provide a folding electric bed with synchronously controlled lifting by left and right motors, in order to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a folding electric bed with synchronous lifting and lowering control by left and right motors, including a front frame, a rear frame hinged to the front frame, a buttocks board fixedly connected to the front frame and the rear frame, a lumbar board hinged to one side of the buttocks board, a back board hinged to one side of the lumbar board, a leg board hinged to the other side of the buttocks board, a footboard hinged to the other side of the leg board, a backrest push rod hinged to the front frame, a backrest bracket hinged to the output end of the backrest push rod, and both ends of the backrest bracket hinged to the front frame, a leg push rod hinged to the rear frame, a legrest bracket hinged to the output end of the leg push rod, and the legrest bracket fixedly connected to the legboard.

[0005] As a further technical solution of the present invention, the buttocks bed board includes a front board and a rear board, and the front board is fixedly connected to the front frame, the rear board is fixedly connected to the rear frame, a fourth hinge plate is fixedly connected to the front board, a third hinge plate is hinged to the fourth hinge plate, and the third hinge plate is fixedly connected to the lumbar bed board.

[0006] As a further technical solution of the present invention, a fifth hinge plate is fixedly connected to the rear plate, a sixth hinge plate is hinged to the fifth hinge plate, and the sixth hinge plate is fixedly connected to the leg bed board.

[0007] As a further technical solution of the present invention, a second hinge plate is fixedly connected to the lumbar bed board, and a first hinge plate and a ninth hinge plate are hinged to the second hinge plate. The first hinge plate is fixedly connected to the back bed board, and the ninth hinge plate is hinged to the back support.

[0008] As a further technical solution of the present invention, a seventh hinge plate is fixedly connected to the leg bed board, an eighth hinge plate is hinged to the seventh hinge plate, and the eighth hinge plate is fixedly connected to the foot bed board.

[0009] As a further technical solution of the present invention, the two ends of the back support are fixedly connected to a fixing frame, one end of the fixing frame is hinged to the front frame, and the other end of the fixing frame is rotatably connected to a roller.

[0010] As a further technical solution of the present invention, a first Hall sensor is fixedly connected to the back push rod, and a second Hall sensor is fixedly connected to the leg push rod.

[0011] As a further technical solution of the present invention, a support rod is hinged to the rear frame, and the other end of the support rod is hinged to the footboard.

[0012] As a further technical solution of the present invention, a foot baffle is fixedly connected to the footboard.

[0013] As a further technical solution of the present invention, both the front frame and the rear frame are fixedly connected with support legs.

[0014] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention designs a folding electric bed with synchronously controlled lifting by left and right motors. The bed board is subdivided into five areas: back, waist, hips, legs, and feet. These areas are connected by hinges. This design allows the bed board to better conform to the human body curve during lifting, conforming to ergonomic principles. In particular, the introduction of the lumbar bed board allows it to rotate synchronously when the back is raised, effectively reducing the pressure caused by mattress bending and providing a more comfortable user experience. Addressing the stability issues of single-push-rod drives in existing technologies, this invention employs a synchronous drive method with dual motors for the back and legs, which not only increases the thrust but also makes the bed frame more stable. The lifting and lowering are smoother, and the load on the bed frame is effectively distributed, reducing the force on individual push rods and thus significantly improving the overall lifespan of the bed. Hall sensors are integrated into the electronic control system to monitor the operating status of the push rods on both sides in real time. When the system detects a discrepancy in the operating distance of the two push rods, it will immediately stop the bed frame's movement, effectively avoiding the risk of bed frame damage caused by left and right asynchrony, and greatly improving the safety and reliability of the bed frame. At the same time, the bed frame adopts a folding packaging method, which greatly reduces the transportation volume and lowers transportation costs while maintaining the integrity of the bed frame structure. The folded bed frame is also lighter and easier for users to move and install, improving the practicality and convenience of the product. Attached Figure Description

It also provides some support for the user's feet, especially when the bed is tilted, reducing the feeling of the feet being suspended and increasing overall comfort. Support legs 1 are fixedly connected to both the front frame 2 and the rear frame 3.

[0025] Working principle: The main body of this invention consists of support legs 1, a front frame 2, a rear frame 3, a backrest board 4, a lumbar support board 5, a hip support board 6, a leg support board 7, and a foot support board 8. The hip support board 6 comprises a front board 61 and a rear board 62. The front board 61 is fixed to the front frame 2, and the rear board 62 is fixed to the rear frame 3. The lumbar support board 5 and the front board 61 are connected by a third hinge plate 12 and a fourth hinge plate 13. The backrest board 4 and the lumbar support board 5 are connected by a first hinge plate 10 and a second hinge plate 11. The leg support board 7 and the foot support board 8 are connected by a support leg 1, a front frame 2, a rear frame 3, a backrest board 4, a lumbar support board 5, a hip support board 6, a leg support board 7, and a foot support board 8. The bed board 62 is connected by the fifth hinge plate 14 and the sixth hinge plate 15. The leg bed board 7 and the foot bed board 8 are connected by the seventh hinge plate 16 and the eighth hinge plate 17. These structures together form the main structure of the folding electric bed. The backrest bed board 4 is equipped with two backrest push rods 18. When the backrest bed board 4 is raised or lowered, the two backrest push rods 18 move synchronously to push the fixing frame 22. The leg bed board 7 is equipped with two leg push rods 24. When the leg bed board 7 is raised or lowered, the two leg push rods 24 move synchronously to push the leg support 26. During use, the two… The symmetrically arranged backrest push rods 18 push the backrest support 20. The backrest support 20 rotates through the hinge point of the fixing frame 22 on the front frame 2 and pushes the backrest bed board 4 to unfold through the rollers 23. At the same time, the hinge position of the backrest bed board 4 and the lumbar bed board 5 is lifted by the ninth hinge plate 21, thereby lifting the lumbar bed board 5. The leg push rods 24 push the leg support 26 to lift the leg bed board 7. Meanwhile, the foot bed board 8 is supported by the support link 27. During use, the first Hall sensor 19 and the second Hall sensor 25 monitor the operation respectively. The operation status of the back push rods 18 and the leg push rods 24 on both sides is monitored in real time by Hall sensors built into the push rod motors. The control box keeps the operation status of the two push rods in the same position consistent. When the system detects that the movement distance of the push rods on both sides is asynchronous, it will immediately stop the movement of the bed frame, effectively avoiding the risk of bed frame damage caused by the asynchrony between the left and right sides. When folding and storing, the front frame 2 and the rear frame 3 are folded and stored with all the bed boards unfolded horizontally.
