Description
Technical Field
[0001] This utility model relates to the field of lifting bed technology, specifically to an integrated modular intelligent lifting bed. Background Technology
[0002] In modern society, sleep quality has a crucial impact on people's health and quality of life. Problems such as light sleep, sleep interruption, and insomnia not only reduce people's quality of life, but may also indirectly lead to chronic diseases such as depression and hypertension, and increase medical expenses. With the increasing popularity of smart homes, people's need to improve sleep quality is becoming more and more urgent.
[0003] However, existing smart lift-up beds have many problems that urgently need to be solved. In terms of space occupation, their structural design occupies a large amount of space under the bed, which makes it extremely inconvenient for users to clean under the bed, making it difficult to thoroughly clean dust and debris, affecting the cleanliness of the bedroom environment. At the same time, the large space occupation also makes the bed extremely inconvenient to transport, increasing transportation costs and difficulties, which is not conducive to the circulation and popularization of the product. Moreover, this structure also makes the maintenance and disassembly of the core lifting mechanism difficult. Once a malfunction occurs, maintenance personnel need to spend a lot of time and energy to operate, which not only affects the normal use of the user, but also increases maintenance costs. In terms of compatibility, existing smart beds also perform poorly. Their basic bed frame facilities and intelligent lifting structure are tied together and cannot be separated. Users cannot customize the bed frame themselves and can only choose to purchase and install the entire bed. This not only limits users' choices and fails to meet their personalized needs for bed frame style, materials, etc., but also makes the overall implementation cost too high, increasing the economic burden on users. Moreover, the tied structure further exacerbates the inconvenience of transportation, which is not conducive to the promotion and application of the product. In conclusion, current smart beds on the market have significant shortcomings in terms of space utilization, compatibility, transportation, and maintenance, and cannot adequately meet users' actual needs. Developing a better smart bed-related device is of great practical significance. Utility Model Content
[0004] In order to solve the problems existing in the prior art, this utility model provides an integrated modular intelligent lifting bed, which solves the problems of existing lifting beds having a large space occupied under the bed, difficult transportation, difficult maintenance and disassembly, and poor compatibility of integrated design.
[0005] To solve the above problems, the technical solution of this utility model is as follows: An integrated modular intelligent lifting bed includes a bed frame, with fixed support beams at both ends inside the bed frame, and bed board support beams on both sides of the fixed support beams. A drive device is provided between the two fixed support beams. The two ends of the drive device are fixed to the fixed support beams through back connecting beams and leg connecting beams. The back connecting beams and leg connecting beams are connected to the fixed support beams through mounting seats. The two ends of the drive device are also rotatably connected to a back rotating device and a leg rotating device. Several bed boards are connected to the upper ends of the drive device, leg rotating device, and back rotating device. The device also includes a controller.
[0006] Furthermore, the bed board includes a backrest board, a lumbar board, a legboard, and a footboard that are hinged together, with the lumbar board fixedly connected to the drive device.
[0007] Furthermore, the drive device includes a drive fixing housing connected to the back connecting beam and the leg connecting beam, and the leg drive assembly and the back drive assembly are symmetrically arranged inside the drive fixing housing.
[0008] Furthermore, the back drive assembly includes a drive motor with its output end located inside the drive housing, a lead screw connected to the worm gear at the output end of the drive motor via a connecting assembly, a back slider and a stroke block fixed on both sides of the lead screw, a slide rail slidably connected to the stroke block inside the drive housing, and a limit block on one side of the stroke block.
[0009] Furthermore, the connecting assembly includes a cover shell that covers the output end of the drive motor and is fixedly disposed inside the drive housing. A transmission component that is rotatably connected to the lead screw is provided inside the cover shell. Limiting rings are fixed at both ends of the transmission component. A transmission gear that meshes with the worm gear at the output end of the drive motor is fixed between the two limiting rings. A limiting groove that matches the limiting rings is provided inside the cover shell.
[0010] Furthermore, a left limit switch and a right limit switch are provided at both ends of the slide rail, and the travel block contacts the two limit switches when it slides.
[0011] Furthermore, the leg drive assembly and the back drive assembly have the same structure and are arranged symmetrically.
[0012] Furthermore, the back rotation device includes a back rotation hook hinged to the drive fixed shell. One end of the back rotation hook is fixedly connected to a back rotation rod, and the end of the back rotation rod is rotatably connected to a back connecting rod. Both ends of the back connecting rod are provided with pulleys that contact the back bed board. At the end of the back connecting beam, there is a hook body rotation block that allows the hook body of the back rotation hook to pass through and restricts the sliding trajectory of the back rotation hook.
[0013] Furthermore, the leg rotation device includes a leg rotation hook hinged to the drive fixed shell. One end of the leg rotation hook is fixedly connected to a leg rotation rod. Two foot fixing seats are provided at the bottom of the foot bed board. The end of the leg rotation rod is rotatably connected to a leg connecting rod. The leg connecting rod is rotatably connected to the foot fixing seats.

Users can adapt the mounting base according to the existing bed frame size and complete the intelligent upgrade without replacing the whole bed, which reduces the cost of use and expands the scope of application.
[0016] The symmetrical drive structure ensures stable operation. The drive unit features symmetrically arranged leg drive assemblies and back drive assemblies, which are identical in structure and independently controlled. They can drive the leg and back bed boards to rise and fall separately. Through lead screw transmission and slider linkage, combined with limit switches, the lifting angle is precisely controlled, ensuring smooth operation and accurate positioning of the bed board, thus improving user safety and comfort.
[0017] With optimized space utilization and convenient installation and maintenance, the drive unit is integrated between two fixed support beams, resulting in a compact overall structure that reduces the space occupied under the bed and facilitates cleaning and daily maintenance. The use of lightweight structures such as pulleys and connecting rods reduces the drive load and simplifies the assembly process. During maintenance, corresponding modules can be disassembled individually without disassembling the entire bed.
[0018] With multi-angle adjustment to adapt to diverse needs, the backrest and legrests can be independently raised and lowered via a rotating mechanism to meet the posture requirements of users in different scenarios such as lying down, reading, and watching movies. The controller can integrate extended functions such as sleep monitoring to achieve intelligent adjustment, build a "sleep-health" linkage system, and enhance the user experience.

Detailed Implementation
[0021] I. Overall structural composition, such as Figure 1-6 As shown.
[0022] like Figure 1-3 As shown, this integrated modular intelligent lifting bed mainly includes a bed frame 1, a backrest connecting beam 4, a leg connecting beam 5, a drive unit 7, a rotating device 9, a bed board 6, and a controller. The specific structure of each part is as follows: Inside the bed frame 1, fixed support beams 2 are provided at both ends. Bed board support beams 3 are provided on both sides of the fixed support beams 2. Support plates can be added to the bottom of the drive device 7, back connecting beam 4, and leg connecting beam 5 to enhance stability. Bed board support beams 3 are vertically connected to both sides of the fixed support beams 2 to assist in supporting the bed board 6. The fixed support beams 2 and the bed board support beams 3 are fixed by bolts or mortise and tenon structures to form a stable rectangular frame.
[0023] like Figure 4 , 5 As shown, the drive unit 7 is located between the two fixed support beams 2 and is the core component for realizing the lifting and lowering of the bed board 6. Specifically, it includes: Drive fixing shell 701: can be made of high-strength plastic or metal, hollow inside to accommodate drive components, with a U-shaped cross section, and both ends are connected to the fixed support beam 2 through the back connecting beam 4 and the leg connecting beam 5. The ends of the connecting beam are bolted to the fixed support beam 2 through the mounting seat 8. The size of the mounting seat 8 can be customized according to the width of the bed frame crossbeam. Leg drive assembly and back drive assembly: symmetrically arranged in the drive fixing housing 701, the two have completely identical structures, and respectively control the raising and lowering of the leg bed board 603 and the back bed board 601.
[0024] like Figure 1 , 4 The rotating device 9 includes a back rotating device and a leg rotating device, used to transmit the power of the drive device 7 to the bed board 6 to achieve angle adjustment. like Figure 2 , 4 As shown, the back rotation device consists of a back rotation hook 901, a back rotation rod 902, a back connecting rod 903, and a pulley 904. like Figure 3 , 4 As shown, the leg rotation device consists of a leg rotation hook 1001, a leg rotation rod 1002, a leg connecting rod 1003, and a foot fixing seat 1004.
[0025] like Figure 2 , 3 As shown, the bed board 6 consists of a backrest board 601, a lumbar board 602, a legrest board 603, and a footrest board 604. The bed boards 6 are connected by hinges and can rotate relative to each other. The lumbar board 602 can be fixed to the drive fixing shell 701 by bolts and fixing plate 12, serving as the fixing reference for the entire bed board 6.
[0026] The controller can be placed near the bedside for easy user operation. It is electrically connected to the drive motor 702 and limit switch of the drive device 7 via wires to control the start and stop of the bed board 6 lifting and the angle adjustment. It supports basic button control or can be upgraded to intelligent control (such as Bluetooth remote control and sleep monitoring linkage).
[0027] II. Details and Assembly of Core Components Drive assembly (taking the rear drive assembly as an example) Drive motor 702: The output end is provided with a worm gear 703, which is fixed in the cover shell 704 inside the drive fixing shell 701; Connection component: A transmission component 705 is provided inside the housing 704. Limiting rings 706 are provided at both ends of the transmission component 705. A transmission gear 707 that meshes with the motor worm gear 703 is fixed between the two limiting rings 706. A limiting groove 708 that matches the limiting rings 706 is provided inside the housing 704. Lead screw 709: It is coaxially connected to the transmission component 705. As the transmission component 705 rotates, the lead screw 709 slides left and right. Back slider 710 and stroke block 711: fixed on both sides of lead screw 709, and move axially with lead screw 709; drive fixed housing 701 is provided with slide rail 712 matching stroke block 711, and slide rail 712 is provided with left stroke switch 713 and right stroke switch 714 at both ends (used to control motor start and stop and limit lifting range), limit block 715 prevents stroke block 711 from slipping; Assembly relationship: After the drive motor 702 starts, the worm gear 703 drives the transmission gear 707 to rotate, the transmission component 705 drives the lead screw 709 to rotate, and then drives the back slider 710 and the stroke block 711 to slide along the slide rail 712.
[0028] Rotary device assembly like Figure 4 , 5 As shown in Figure 6, one end of the back rotating hook 901 is fixedly connected to the back rotating rod 902, and the end of the back rotating rod 902 is rotatably connected to the back connecting rod 903. Both ends of the back connecting rod 903 are provided with pulleys 904 that contact the back bed board 601. The pulleys 904 contact the bottom of the back bed board 601 (to reduce friction when the bed board is raised and lowered). At the end of the back connecting beam 4, there is a hook body rotating block 11 that allows the hook body of the back rotating hook 901 to pass through and restricts the sliding trajectory of the back rotating hook 901.
[0029] The assembly structure of the leg rotation device is basically the same, the difference lies in the connection method with the footrest 604.

Work Process 601 Liftable Backrest like Figure 1 , 2 As shown in Figures 5 and 6, when the drive motor 702 of the back drive assembly is started, the worm gear 703 drives the transmission gear 707 to rotate, the transmission component 705 drives the lead screw 709 to move to the left, the back slider 710 slides to the left, the back slider 710 pushes the back rotating hook 901 to slide along the hook body rotating block 11, the back rotating rod 902 is lifted with the back rotating hook 901, and through the back connecting rod 903 drives the pulley 904 to lift the back bed board 601, realizing the back rise; when the travel block 711 slides along the slide rail 712 to touch the left travel switch 713, the drive motor 702 stops running, and the back bed board 601 maintains the current angle; When the reverse start drive motor 702 is activated, the back slider 710 moves in the reverse direction, the back rotating hook 901 is reset, the back bed board 601 descends, and when the travel block 711 touches the right travel switch 714, the drive motor 702 stops and the back bed board 602 is reset.
[0031] like Figure 3As shown, the legrest 603 and footrest 604 are raised and lowered in a similar manner to the backrest, except that the footrest 604 is hinged to the legrest 603, and the legrest 603 is hinged to the lumbar support 602. When the footrest 1004 is pulled, the footrest 604 and the legrest 603 are raised synchronously around the lumbar support 602, thus raising the legs.
[0032] Controller Function Implementation Basic functions: The back and leg drive motors can be independently controlled to rotate forward and backward via the controller buttons, enabling multi-angle adjustment of the bed board (such as fixing any angle within the range of 0°-45°). Functional block 13 can be expanded to include: after upgrading the controller, sleep monitoring sensors (such as pressure sensors and heart rate sensors) can be connected to automatically adjust the bed board angle according to the user's sleeping posture; in the case of a double bed, the two bed boards can be independently controlled through dual controllers.
[0033] IV. Applicable Scenarios and Advantages This integrated modular smart lift bed is suitable for home bedrooms, nursing homes, hospital care, and other scenarios. Its advantages are: The modular design separates the drive unit 7 from the bed frame 1, allowing users to directly upgrade their existing bed without replacing the entire bed.
