Description

Technical Field

[0001] This invention relates to the field of electric bed technology, specifically a multi-section electric bed. Background Technology

[0002] Most electric beds currently on the market only have back and leg lift functions. These beds typically divide the bed board into simple back, hip, and leg areas, with few segments and a lack of ergonomic design features, making it difficult to conform to the human body's curves, as shown in patent CN221931662U. Some electric beds, while adding head and lumbar lift functions, have the lumbar lift fixed in the hip area, only allowing vertical movement without angle adjustment; furthermore, each area relies on electric push rods, simply adding functions to a regular electric bed, also lacking ergonomic design. The added steel frame structure and motor further increase costs, as seen in patent CN202820452U. This situation makes it difficult for existing electric beds to balance comfort and economy, failing to meet users' dual needs for ergonomic fit and cost control. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-segment electric bed to solve the problems mentioned in the background art, such as the electric bed board having few segments, poor ergonomic fit, limited head and waist adjustment functions, and high cost.

[0012] Compared with the prior art, the beneficial effects of the present invention are: With independent linkage adjustment of multiple bed board sections for the head, back, waist, legs, and feet, the electric bed can fully conform to the physiological curvature of the human head, back, waist, legs, and feet, forming all-round ergonomic support from head to toe. This solves the problems of existing electric beds having few sections and poor fit, greatly improving the comfort when lying down, and is especially suitable for users who are bedridden for a long time or have high requirements for sleep comfort. By replacing some mechanical structures and electric push rods with self-locking gas springs and self-locking hinges, the head and waist lifting drive structure is simplified, reducing the use of complex iron frames and motors. This achieves flexible adjustment of the head and waist areas while avoiding cost spikes caused by adding new functions. Under the premise of ensuring multi-stage ergonomic adjustment functions, the manufacturing cost of the electric bed is effectively reduced, and the product's market competitiveness is enhanced.

[0016] Please see Figure 1-8 This invention provides a multi-section electric bed, comprising a headboard 1, a backboard 2, a lumbar board 3, a hipboard assembly, a thighboard 6, a calfboard 7, and a footboard 8, which are sequentially hinged together by a bed board connector 22. The hipboard assembly includes a hipboard first 4 and a hipboard second 5 fixedly connected. The headboard 1 has a headboard tail seat 12 at its bottom, and the backboard 2 has a backboard tail seat 13 at its bottom. The headboard 12 is connected to the headboard via the headboard tail seat 14. One end of the push rod 20 is hinged, and the backrest bed board tail seat 13 is hinged to the other end of the head push rod 20 through the backrest bed board tail seat hinge 15. The bottom of the backrest bed board 2 is provided with a roller bracket 18 and a roller bracket hinge 23. The roller bracket 18 is hinged to one end of the back push rod 19, and the other end of the back push rod 19 is hinged to the bed frame. The bottom of the lumbar bed board 3 is provided with a lumbar push rod 16 and a lumbar lifting mechanism. The bottom of the thigh bed board 6 is fixed with a leg frame 9, and the leg frame 9 is connected to one end of the foot push rod 21. The footrest 21 is hinged to the bed frame at one end. Specifically, the headboard 1 and backboard 2 are connected by the headboard tail seat 12, backboard tail seat 13, headrest 20, headboard tail seat hinge 14, and backboard tail seat hinge 15 to achieve head area angle adjustment. The backboard 2 is connected to the backrest push rod 19 via roller bracket 18 to achieve backrest height and angle adjustment. When the roller bracket 18 rotates, it drives the roller support... The hinge 23 lifts the connecting piece (22) between the backrest and lumbar bed board, thereby raising the lumbar bed board 3. The lumbar lifting mechanism is driven by the lumbar push rod 16 or the self-locking gas spring 25, enabling flexible adjustment of the lumbar region. The thigh, calf, and foot bed boards are linked with the foot push rod 21 through the leg frame 9, calf connecting rod 10, thigh connecting rod 11, and foot push rod 21, completing multi-segment angle adjustments for the legs and feet. All bed boards are hinged together through the bed board connecting piece 22 to form a multi-segment linkage structure. This allows multiple bed boards to be adjusted independently and in linkage, making the electric bed fully conform to the human body curve, meeting ergonomic requirements, while optimizing the drive structure layout and reducing costs while ensuring functionality.

[0017] The headboard tailstock 12 is fixed to the bottom end face of the headboard 1, and the backboard tailstock 13 is fixed to the bottom end face of the backboard 2. Both the headboard tailstock 14 and the backboard tailstock hinge 15 are pin-type hinge structures. Specifically, by fixing the headboard tailstock 12 and the backboard tailstock 13 to the bottom of their respective bed boards, and cooperating with the pin-type hinges 14 and 15, the head push rod 20 stably drives the connection between the headboard 1 and the backboard 2 to rotate during extension and retraction. This ensures structural stability and smooth rotation during head area adjustment, improving the accuracy and reliability of head adjustment. A self-locking hinge 24 can be used to directly connect the headboard 1 and the backboard 2 to raise the headboard.

[0018] The rollers on the roller bracket 18 are in complete contact with the bottom surface of the backrest bed board 2. The roller bracket hinge 23 is hinged to the roller bracket 18, and the other end of the roller bracket hinge 23 is hinged to the connecting piece 22 of the backrest bed board and the lumbar bed board. Specifically, the rollers 18 are in contact with the bottom of the backrest bed board 2, and the backrest push rod 19 extends and retracts to drive the roller bracket to rotate. The rollers 18 roll at the bottom of the backrest bed board 2 to lift the backrest bed board 2.

[0019] One end of the roller bracket hinge 23 is hinged to the roller bracket 28, with the hinge point located between the roller bracket and the push rod hinge point and the roller bracket and the frame hinge point. The other end is hinged to the connecting piece 22 of the backrest and lumbar bed board. When the roller bracket 18 rotates, it will drive the roller bracket hinge 23 and lift the connecting piece 22 of the backrest and lumbar bed board, thereby driving the lumbar bed board 3 to rise.

[0020] The two ends of the lumbar push rod 16 are hinged to the lumbar lifting mechanism, which is fixed on the lumbar bed board 2. Specifically, the movement of the lumbar lifting mechanism is controlled by the extension and retraction of the lumbar push rod 16 to realize the vertical lifting of a part of the lumbar bed board. The lumbar push rod 16 can be replaced with a self-locking gas spring 25.

[0021] The end of the thigh bed board 6 is hinged to the end of the lower leg bed board 7. One end of the lower leg connecting rod 10 is hinged to the bed frame, and the other end of the lower leg connecting rod 10 is hinged to the connector on the lower leg bed board 7. The end of the lower leg bed board 7 is hinged to the end of the foot bed board 8. One end of the thigh connecting rod 11 is hinged to the bed frame, and the other end of the thigh connecting rod 11 is hinged to the connector on the foot bed board 8. Specifically, the thigh bed board 6 and the lower leg bed board 7 are hinged to the lower leg connecting rod 10, and the lower leg bed board 7 and the foot bed board 8 are hinged to the thigh connecting rod 11. One end of the lower leg connecting rod 10 and the thigh connecting rod 11 is hinged to the side wall of the leg frame 9. When the leg frame 9 extends and retracts with the foot push rod 21, it drives the thigh, lower leg, and foot bed boards to adjust their angles in a coordinated manner.

[0022] The bed board connector 22 is a double-pin hinge structure. The bed board connector 22 corresponds to the connection end of the hinged front bed board 1 and the back bed board 2, the connection end of the back bed board 2 and the lumbar bed board 3, the connection end of the lumbar bed board 3 and the buttock bed board 4, the connection end of the buttock bed board 5 and the thigh bed board 6, the connection end of the thigh bed board 6 and the lower leg bed board 7, and the connection end of the lower leg bed board 7 and the foot bed board 8. Specifically, by using the double-pin hinge structure of the bed board connector 22, the connection ends of each bed board are connected, so that the adjacent bed boards are stably hinged and can rotate relative to each other.

[0023] A gas spring switch 17 is provided on the side of the self-locking gas spring 25. The gas spring switch 17 is sealed to the control end of the self-locking hinge 24 via a cable. Specifically, by sealing the gas spring switch 17 to the control end of the self-locking hinge 24 via a cable, operating the gas spring switch 17 can control the extension and retraction of the self-locking hinge 24, thereby adjusting the vertical lifting of the lumbar bed board 3 area.

[0024] The top surface of the leg frame 9 is completely fitted with the bottom end face of the thigh bed board 6 and fixed with bolts. The hinge position of the foot push rod 21 and the leg frame 9 is located in the vertical middle area of ​​the leg frame 9. Specifically: the top surface of the leg frame 9 is completely fitted with the bottom end face of the thigh bed board 6 and fixed with bolts. The foot push rod 21 is hinged in the vertical middle area of ​​the leg frame 9. When the foot push rod 21 extends or retracts, it drives the leg frame 9 and the connected thigh bed board 6 and other components to move together.

[0025] In this invention, in the head area: the headboard 1 and the backboard 2 are linked by the headboard tail seat 12, the backboard tail seat 13, the head push rod 20, the headboard tail seat 14 of the hinge, and the backboard tail seat hinge 15. The extension and retraction of the head push rod drives the headboard to rotate relative to the backboard, thereby adjusting the head angle. In the back area: the extension and retraction of the back push rod 19 drives the roller bracket 18 to rotate. The rollers on the roller bracket 18 roll at the bottom of the backboard 2, thereby raising the backboard and adjusting its angle. In the waist area: the extension and retraction of the waist push rod 16 controls the movement of the waist lifting mechanism, thereby achieving vertical lifting and lowering of the upper part of the waistboard 3. In the leg and foot area: the extension and retraction of the foot push rod 21 drives the leg frame 9 to move. Through the linkage of the calf connecting rod 10 and the thigh connecting rod 11, the thigh board 6, the calf board 7, and the foot board 8 are adjusted in sequence to fit the curve of the lower limbs. Each section of the bed board is stably hinged by a double-pin type bed board connector 22, ensuring structural reliability and motion synchronization during adjustment. This allows multiple bed boards to be adjusted independently and in conjunction, making the electric bed perfectly conform to the human body curve and meet ergonomic requirements. At the same time, the drive structure layout is optimized, and some mechanical structures and electric push rods are replaced by self-locking gas springs 25 and self-locking hinges 24, reducing costs while ensuring functionality.
