Description

Technical Field

[0001] This utility model relates to the field of electric bed technology, specifically to a lifting structure for a double-headed, single-tailed electric bed. Background Technology

[0002] To improve comfort while lying in bed, an adjustable electric bed has appeared on the market.

[0003] Referring to the electric bed disclosed in application number 202322007092.3, an electric bed includes a bed frame with a plurality of support plates mounted on the frame. Adjacent support plates are hinged together. The bed frame has multiple flip-up mechanisms. The support plates include a back support plate, a hip support plate, a first leg support plate, and a second leg support plate. Both the back support plate and the first leg support plate are connected to a flip-up mechanism. A connecting rod is provided between the second leg support plate and the bed frame, with both ends of the connecting rod hinged to the second leg support plate and the bed frame, respectively. This technical solution enables the flipping up of the back support plate and the first leg support plate, meeting different user needs.

[0004] However, this technical solution typically uses a flip-up mechanism to adjust the back support panel as a whole. When the electric bed is used in a double-person scenario, if one person needs to adjust the angle of the back support panel (such as getting up or lying down), the flip-up mechanism will cause the entire back support panel to rotate synchronously. This will cause the other person to be lifted up even if they only want to stay in a flat resting position, which will seriously affect the other person's resting experience and cannot meet the needs of two people to adjust independently. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a lifting structure for a double-headed, single-tailed electric bed.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A double-headed single-tailed electric bed lifting structure includes two side beams distributed on the left and right, and a front base frame, a fixed frame, and a rear base frame arranged from front to back between the two side beams. The left and right ends of the front base frame, the fixed frame, and the rear base frame are respectively connected to the two side beams and combined to form a bed frame. A reinforcing frame located between the front base frame and the fixed frame is connected between the two side beams, and a reinforcing beam located below the fixed frame is connected between the reinforcing frame and the rear base frame. The reinforcing frame and the front base frame are connected by two mounting beams arranged from left to right between the two side beams. The mounting beam on the left side forms a left drive space with the side beam on the left side, and the mounting beam on the right side forms a right drive space with the side beam on the right side. Both the left drive space and the right drive space are equipped with a forward tilting mechanism.

[0007] In this utility model, the front tilting mechanism includes a front drive frame and a front electric drive cylinder. The two ends of the front drive frame are respectively hinged to the mounting beam and the side beam. The front drive frame is provided with two front drive arms, and each front drive arm of the front drive frame is provided with a front drive roller. The fixed end of the front electric drive cylinder is hinged to the front hinge seat of the front base frame, and the telescopic end is hinged to the front drive seat of the front drive frame.

[0008] In this utility model, the two side beams are connected by a rear-flipping mechanism located between the fixed frame and the rear base frame.

[0009] In this utility model, the rear tilting mechanism includes a rear drive frame, a rear electric drive cylinder, and a follower rod. The two ends of the rear drive frame are respectively hinged to two side beams. The rear drive frame is provided with two rear drive arms, and each of the rear drive arms of the rear drive frame is provided with a rear drive roller. The fixed end of the rear electric drive cylinder is hinged to the rear hinge seat of the rear base frame, and the telescopic end is hinged to the rear drive seat of the rear drive frame. One end of the follower rod is hinged to the side beam, and the other end is hinged to the rear connecting seat.

[0010] In this utility model, the front base frame includes a front base beam and two front side seats fixed on the upper part of the front base beam, each front side seat being connected to a side beam; the upper end of the front side seat is provided with a front adapter groove, and the side beam is embedded into the front adapter groove and fixedly connected to the front side seat.

[0011] In this utility model, the reinforcing frame includes a reinforcing bottom beam and two reinforcing side seats and two reinforcing middle seats fixed on the upper part of the reinforcing bottom beam. Each reinforcing side seat is connected to a side beam, and the reinforcing beam is connected to the reinforcing bottom beam. The front base frame also includes two front middle seats fixed on the upper part of the front bottom beam. The front and rear corresponding reinforcing middle seats and front middle seats are connected to a mounting beam.

[0012] In this utility model, the upper ends of the reinforced middle seat and the front middle seat are provided with mounting grooves, the front and rear ends of the mounting grooves are mounting openings for the mounting beam to pass through, and the bottom surface of the mounting groove is a mounting plane that supports the mounting beam.

[0013] In this utility model, the rear base frame includes a rear base beam and two rear side seats fixed on the upper part of the rear base beam. Each rear side seat is connected to a side beam. The reinforcing beam is connected to the rear base beam. The upper end of the rear side seat is provided with a rear adapter groove. The side beam is embedded into the rear adapter groove and fixedly connected to the rear side seat.

[0014] In this invention, the bottoms of the front bottom beam, rear bottom beam, and reinforcing bottom beam are flush or nearly flush, and / or the lower ends of the front and rear base frames are equipped with at least two support feet.

[0015] In this utility model, end sleeves are welded and fixed at both ends of the reinforcing beam. The end sleeves are provided with end slots. The reinforcing bottom beam of the reinforcing frame passes through the end slot of the end sleeve located at the front end from left to right and is fixedly connected to the end sleeve. The rear bottom beam of the rear base frame passes through the end slot of the end sleeve located at the rear end from left to right and is fixedly connected to the end sleeve.

[0016] The beneficial effects of this utility model are as follows: This utility model is equipped with two forward-flipping mechanisms. One mechanism drives the back support plate corresponding to the left drive space, and the other drives the back support plate corresponding to the right drive space. This allows each back support plate to be driven independently by its corresponding forward-flipping mechanism, enabling independent adjustment of the two back support plates. When the electric bed is used in a double-person scenario, users can flexibly adjust their respective back support angles according to their needs. This avoids the interference caused to the other user by the overall back support plate flipping during single-person adjustment in existing technologies. It effectively improves the independence and comfort of double-person use and meets the needs of independent adjustment in double-person scenarios. Furthermore, the side beams, front base frame, fixed frame, rear base frame, reinforcing frame, reinforcing beam, and mounting beam are all connected by bolts, achieving full disassembly of the main components. This reduces the product's packaging volume, facilitates logistics and transportation, and makes parts replacement convenient, providing convenience for after-sales service.
