detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the scope of protection of the present utility model.

As shown in Figures 1-5, the present invention provides a chair-changing electric bed, which includes:

Bed frame 1;

The bed board group 2 is slidably arranged on the bed frame 1, and the bed board group 2 includes at least two hingedly connected bed boards;

The extension end of the electric telescopic rod 3 is hinged on the outermost bed board on one side of the bed board group 2, and the fixed end of the electric telescopic rod 3 is hinged on any bed board except the outermost bed board mentioned above;

The guide part 4 is fixedly arranged on the side of the bed frame 1 at the output end of the electric telescopic rod 3. The guide part 4 is assembled to allow the extension end of the electric telescopic rod 3 to move up and down inside, and the extension end rises to the highest point When the bed board set 2 is in a straight state, when the extended end is lowered to the lowest point, the bed board connected with the extended end swings downwardly at an angle of less than 90°;

When the electric telescopic rod 3 is retracted, its extended end will move downward in the guide 4 and drive the outermost bed board to swing downward. The rod 3 continues to retract, and the extended end is located at a fixed position. The fixed end will drive the bed plate group 2 to move towards the extended end on the bed frame 1. At this time, the outermost bed plate continues to swing downwards and is connected to the The end connecting the other sideboard on the outermost sideboard to the outermost sideboard will lift upwards and gradually tilt up. At this time, after the human body sits on the electric bed that turns into a chair, it will sit on the raised floorboard. The center of gravity of the human body will shift backwards, which can prevent the human body from slipping off the bed. The electric bed after changing the chair will support the human body more stably.

In one embodiment, the bed board set 2 includes two hingedly connected bed boards, and the extended end and the fixed end of the electric telescopic rod 3 are respectively hinged on the two bed boards. After the two bed boards are assembled so that the extended ends are lowered, the fixed ends correspond to The hinged end of the bed board and the other bed board will tilt upwards.

In one embodiment, the bed board includes a plurality of bed boards that are hingedly connected in sequence, and a bed board is spaced between the bed board hinged at the fixed end of the electric telescopic rod 3 and the bed board hinged at its extension end. The connection between the bed board corresponding to the output end and the other bed board has an upward lifting process.

The guide 4 is a longitudinally distributed guide rail 41. The guide rail 41 has a "U"-shaped guide groove 42. Both sides of the guide rail 41 are provided with limit grooves 43 communicating with the guide groove 42. The extension end of the electric telescopic rod 3 is located at In the guide groove 42, there are limit rods 44 extending into the limit groove 43 on both sides. When the electric telescopic rod 3 expands, the telescopic end will drive the limit rod 44 to move down in the limit groove 43, and the electric telescopic rod The extended end of the rod 3 will move downward synchronously. At the same time, the outermost bedboard will swing downward following the extended end. When the limit rod 44 moves to the bottom of the guide groove, the downward swing angle of the outermost bedboard is less than In the 90° state, at this time, the outermost bedboard has space to continue swinging. As the electric telescopic rod 3 continues to shrink, the extended end cannot continue to move. At this time, it will drive the fixed end to move, and then drive the bedboard group to extend in 2 directions. Moving in the direction of the exit, the bed board connected to the outermost bed board will tilt upwards, thereby realizing the technical effect of the solution and solving the technical problem.

It also includes an auxiliary bed frame 5. The auxiliary bed frame 5 is slidably arranged on the main bed frame 1, and the bed plate group 2 is arranged on the auxiliary bed frame 5. Specifically, wheel grooves are provided on both sides of the main bed frame 1, and the wheel grooves are arranged Rollable rollers are installed on the side of the auxiliary bed frame 5 so that the auxiliary bed frame 5 can be translated under the action of the electric telescopic rod 3.

The bed board set 2 includes sequentially hinged bed board one 21, bed board two 22, bed board three 23, bed board four 24, bed board five 25 and bed board six 26. The protruding end is connected to the bed board two 22, and the fixed end is connected to the bed board four 24. When bed board one 21 and bed board two 22 swing down to a vertical state, the connecting end of bed board three 23 and bed board two 22 will tilt upwards. It should be noted that in order to improve the practicality of the electric bed after changing into a chair, it is also possible Set up an electric telescopic rod 3, and assemble it so that after the extension end is extended, the bed plate 23 can be turned upwards. After the electric vehicle is changed into a chair, the bed plate 23 can form a backrest. In order to further improve the practicality, the bed plate 1 Between 21 and bed board two 22, bed board six 26 and bed board five 25 can be detachably connected, and make the overall length of bed board one 21, bed board two 22, bed board three 23, bed board four 24 and bed board five 25 and the length of the bed frame 1 is matched to make the bed board one 21 and the bed board six 26 in a straight state, the overall length of the bed board group 2 is greater than the length of the bed frame 1, so that the electric bed has a longer bed surface, and the detachable bed board 21 and After the bed board 26 is removed, the bed surface is restored to the same length as the bed frame 1, and the length of the bed surface can be expanded according to needs. Among them, the two sides of the bed board 24 are detachably installed with handrails 6 through bolts.
