[0002] As living standards improve, electric beds are gradually entering ordinary households, replacing traditional flat beds. The backrest and legrest lift functions of electric beds are relatively practical, especially when reading or watching TV. Electric beds can adjust the angle to adapt to the most suitable posture for the human body, increasing comfort and relieving fatigue.

[0003] Most electric beds on the market now have their motors installed at the head and tail. When the back and leg panels are raised, the motor and the mechanical structure that houses it are exposed, which affects the aesthetics to some extent. At the same time, the motor is installed at the head, which is close to the user's head, making the motor noise more noticeable and creating a poor user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing electric bed frame motor and motor mounting structure are exposed, which affects the aesthetics, and the motor is mounted at the head, which makes the noise of the motor operation affect the user.

[0010] Furthermore, the intermediate horizontal tube connector is connected to the intermediate horizontal tube.

[0011] Furthermore, the head and tail horizontal tube connectors are connected.

[0012] Furthermore, the lifting clamp is made of plastic with lubricating properties.

[0013] Furthermore, the bed frame assembly includes a backrest assembly and a leg assembly.

[0014] Furthermore, the leg assembly is equipped with a leg support rod and a fixing seat.

[0015] Compared with the prior art, this utility model has the following advantages:

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1-7 The electric bed frame provided by this utility model comprises a bed frame assembly 3 consisting of a central horizontal tube 31, two side tubes 32, head and tail horizontal tubes 33, and a central pull tube 34. A plastic swivel sleeve 321 is fixedly installed on the side tubes 32. The lifting assembly 4 at the back is installed on the plastic swivel sleeve 321 and can rotate freely. The central pull tube 34 connects the lifting assembly 4 at the back, the central horizontal tube 31, and the head and tail horizontal tubes 33. One end of the motor 5 is installed on the lifting assembly 4, and the other end is installed on the central horizontal tube 31. A folding lug 312 is provided on the central horizontal tube 31 of the bed frame, and the upper and lower bed frame assemblies 3 are hinged through the folding lug 312. The operation process is as follows: under the push of the motor 5, the lifting assembly 4 rotates around the plastic swivel sleeve 321. When the swing arm 41 rotates, the roller 42 rolls on the back of the bed board, driving the back of the bed board to rise and fall.

[0030] The structure and movement of the legs are the same as those of the back, and are also adjusted by the lifting component 4. The leg component is equipped with a leg support rod 361 and a fixed seat 362. The leg support rod 361 supports the legs, and the fixed seat 362 fixes the legs to a certain extent, so that the legs are in a relatively comfortable state throughout the entire transformation process.

[0031] When the motor 5 moves, it will simultaneously generate thrust in opposite directions on the lifting assembly 4 and the head and tail horizontal tubes 33, and at the same time, it will exert a pulling force on the middle pull tube 34. This structure, which converts thrust into pulling force, greatly improves the utilization rate of material mechanical properties. While ensuring the strength of the bed frame, it reduces the demand for bed frame materials and lowers the cost of the bed frame.

[0032] The middle pull tube 34 has three slots. The middle slot is equipped with a lifting clamp 341, which is connected to the lifting assembly 4. The lifting frame can rotate freely inside the lifting clamp 341. The middle horizontal tube connector 342 and the head and tail horizontal tube connector 343 are welded to the slots at both ends, respectively. The middle horizontal tube connector 342 is connected to the middle horizontal tube 31, and the head and tail horizontal tube connector 343 is fixedly connected to the head and tail horizontal tube 33.

[0033] In this structure, the lifting clamp 341 uses a plastic with self-lubricating properties. This material ensures that the rotation of the lifting assembly 4 in the lifting clamp 341 is always smooth and without noise. Similarly, the plastic swivel sleeve 321 installed on the side tube 32 uses the same material to prevent the lifting assembly 4 from generating noise during rotation.

[0034] The electric bed frame provided by this utility model features a motor mounted at the hip area, with vertical support tubes ensuring structural strength and load-bearing capacity, while maintaining a simple and aesthetically pleasing design. Positioning the motor at the hip area reduces the impact of motor noise on the user, providing a better user experience. Furthermore, the electric bed frame employs a foldable structure and is assembled using bolts and nuts, reducing welding processes, increasing the utilization rate of plastic powder, and minimizing storage space.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
