Description

Technical Field

[0001] This utility model relates to the field of bed frame device technology, and in particular to a single-motor back-leg linkage electric bed frame. Background Technology

[0002] With social development, technological progress, and improved living standards, people's demand for a high-quality life is increasing. Electric beds, which were originally only used in the medical industry, are now entering people's daily lives.

[0003] Currently, electric beds are generally expensive, with a plethora of functions and varying quality. The high prices deter consumers, making it difficult to find cost-effective products and creating financial strain. The cluttered and redundant functions can be overwhelming and confusing for older consumers. The wide variety of bed models also makes it difficult for consumers to choose the right one for their needs.

[0004] People often feel tired when reading or watching TV in bed for extended periods. To address this, we designed a single-motor back-leg linkage electric bed frame that allows both the back and legs to be raised. Raising the back makes reading, watching TV, and browsing videos in bed more convenient, while raising the legs promotes blood circulation, reduces fatigue, and helps prevent illness.

[0049] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0050] Example 1:

[0051] The main structure of the bed frame is as follows Figure 1 , Figure 4 , Figure 5 As shown: The upper bed frame assembly 2 consists of a bed frame horizontal tube 20, a left side tube assembly 21, a middle pull tube 22, a right side tube assembly 23, and a middle connecting tube 24.

[0052] The lower bed frame assembly 3 consists of the lower bed frame horizontal tube assembly, the lower bed frame left side tube assembly 31, the lower bed frame middle pull tube assembly 32, the lower bed frame right side tube assembly 33, and the lower bed frame middle connecting tube 34.

[0053] The strut assembly 8 includes a leg plate strut fixing member 80 and a leg plate strut 81. The lower bed frame assembly 3 is mounted on the leg plate strut fixing member 80, the leg plate strut fixing member 80 is mounted on the leg plate strut 81, and the leg plate strut 81 is mounted on the bed leg assembly 9.

[0054] Key reference Figure 8 The upper bed frame side tube assembly 21 consists of a side tube 211, a side tube support 212, a first pull tube connector 213, a rotating shaft sleeve support tube 214, a plastic rotating shaft sleeve 215, and an intermediate tube connector 216.

[0055] Key reference Figure 8 and Figure 9The intermediate pull tube assembly 22 consists of an intermediate pull tube 221, a pull tube support 222, a second pull tube connector 223, a lifting frame clamp 224, and a clamp fixing component 225. The left side tube assembly 21 and the right side tube assembly 23 are fixed to the bed frame horizontal tube 20 with screws via the first pull tube connector 213. The intermediate pull tube assembly 22 is fixed to the bed frame horizontal tube 20 with screws via the second pull tube connector 223. The back lifting frame assembly 4 is installed on the plastic swivel sleeves 215 of the left side tube assembly 21 and the right side tube assembly 23 and passes through the lifting frame clamp 224 of the intermediate pull tube 22. The lifting frame clamp 224 is concentric with the plastic swivel sleeve 215, and the clamp fixing component 225 secures the lifting frame clamp 224.

[0056] Key reference Figure 2 , Figure 3 , Figure 6 and Figure 7 The backrest lifting frame assembly 4 can rotate freely. The backrest motor assembly 7 is installed between the backrest motor starting fixing point 71 and the backrest motor and backrest lifting frame pivot point 72. The operation process is as follows: the backrest motor 70 pushes the backrest lifting motor fixing part 41 and drives the backrest lifting frame round tube 40 to rotate, with the rotation center located on the plastic rotating shaft sleeve 215. As the backrest lifting frame round tube 40 rotates, the backrest lifting frame swing arm 42 located on the backrest lifting frame is driven to rotate. At this time, the backrest lifting frame roller 44 on the backrest lifting frame swing arm 42 rolls on the backrest plate 11, thereby making the backrest plate 11 form a certain angle with the upper buttock plate 12, and the backrest plate 11 is raised. The structure of the lower bed frame assembly 3 is similar to that of the upper bed frame assembly 2, and the structure of the leg lifting frame assembly 5 is similar to that of the backrest lifting frame assembly 4, and will not be described again.

[0057] The linkage tube assembly 6 is installed between the pivot point 61 on the back of the linkage tube and the pivot point 62 on the leg of the linkage tube, linking the back lifting frame assembly 4 and the leg lifting frame assembly 5. Figure 2 Using the view as a reference direction, the operation process is as follows: The back lifting frame assembly 4 rotates clockwise at the center of the plastic pivot 215, causing the back pivot point 61 of the linkage tube to rotate clockwise. The back pivot point 61 of the linkage tube, through the linkage tube 60, pulls the leg pivot point 62 of the linkage tube to rotate counterclockwise. The leg pivot point 62 of the linkage tube is located at the end of the leg linkage tube fixing part 52, which is welded and fixed to the round tube 50 of the leg lifting frame. Because the leg pivot point 62 of the linkage tube rotates counterclockwise, the round tube 50 also rotates counterclockwise, with the center of rotation located on the plastic pivot sleeve 215 of the left side tube assembly 31 of the lower bed frame.

[0058] When the back motor starts moving at 70, Figure 2With the view as a reference direction, the backrest plate 11 forms an angle with the upper buttock plate 12 due to the clockwise rotation of the backrest lifting frame assembly 4. The linkage pipe 60 connects the backrest lifting frame assembly 4 and the leg lifting frame assembly 5, causing the leg lifting frame 5 to rotate counterclockwise. The thigh plate 14 forms an angle with the lower buttock plate 13 due to the counterclockwise rotation of the leg lifting frame. The calf plate 15, supported by the support rod assembly 8, will not collide with the lower bed frame 3.

[0059] During operation, the backrest motor 70 exerts opposing forces on the upper bed frame cross tube assembly 20 and the backrest lifting frame assembly 4. However, the two are connected by the upper bed frame intermediate pull tube 22, which converts the thrust of the backrest motor 70 on the backrest lifting frame assembly 4 into a pulling force. This structure effectively improves bed frame strength, increases material utilization, and simplifies the bed frame structure. The lifting frame clamp 224 in the upper bed frame intermediate pull tube 22 structure and the plastic pivot sleeve 215 in the side tube assembly 21 structure are made of a self-lubricating and wear-resistant plastic, ensuring that the backrest lifting frame assembly 4 rotates within them without generating noise.

[0060] Furthermore, all components in both the upper bed frame assembly 2 and the lower bed frame assembly 3 are secured with screws and are entirely detachable, rather than welded. This detachable structure avoids pipe deformation and precision errors caused by welding. It also makes the parts more versatile, reduces storage space, and facilitates future maintenance.

[0061] This single-motor, leg-linked electric bed frame was developed based on market feedback. While ensuring full functionality, structural strength, load capacity, and lifespan, we simplified the bed frame structure as much as possible, reduced manufacturing costs, and improved user experience. Compared to other single-motor electric beds, this one boasts superior load capacity, simple structure, and easy maintenance, offering users a completely new experience.

[0062] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
