Description

Technical Field

[0001] This utility model belongs to the technical field of lifting bases, and in particular relates to a lifting base with an X-bracing structure. Background Technology

[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] In daily use, the lifting function of electric beds is a very practical feature for many elderly people, especially those who need regular care, as it makes getting in and out of bed easier and more convenient.

[0004] The existing swing arm lifting base has displacement in the vertical direction as well as in the front-back direction when it is raised. This structure is not suitable for situations with bed rails or small room spaces, which will cause inconvenience to users and is not conducive to sales. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of existing lifting bases with swing arm structures. When raised, in addition to displacement in the vertical direction, there is also displacement in the front and back direction. This structure is not suitable for situations with bed rails or small room spaces, which will cause inconvenience to users and is not conducive to sales. Therefore, an X-bracing structure lifting base is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An X-bracing structure lifting base includes a fixed base, an active lifting frame, a driven lifting frame, a lifting motor, and an electric bed frame; the fixed base is hinged to the active lifting frame and the driven lifting frame respectively;

[0008] The active lifting frame includes an active swing arm tube, which includes a first roller assembly; the driven lifting frame includes a driven swing arm tube, which includes a second roller assembly; the active and driven swing arm tubes are respectively hinged to a bed frame connecting tube; the bed frame connecting tube and the active and driven swing arm tubes respectively form an X-brace.

[0009] A synchronization tube is installed between the active lifting frame and the driven lifting frame, and a roller is installed at one end of the bed frame connecting tube. The roller is in rolling connection with the fixed base.

[0010] One end of the lifting motor is connected to the fixed base, and the other end is connected to the active lifting frame.

[0011] Preferably, the active swing arm tube is provided with a first round hole, and the fixed base and the active lifting frame are hinged by inserting bolts into the first round hole.

[0012] Preferably, the driven swing arm tube is provided with a second round hole, and the fixed base and the driven lifting frame are hinged by inserting bolts into the second round hole.

[0013] Preferably, a bed frame connector is provided at the end of the bed frame connecting tube away from the roller, and the bed frame connector is fixedly connected to the electric bed frame.

[0014] Preferably, a motor mounting tube is installed on the fixed base, and the lifting motor is connected to the motor mounting tube.

[0015] Preferably, the X-bracing is provided in 4 sets.

[0016] Preferably, each X-bracing forms 2 support points at the top, and the 4 sets of X-bracing form a total of 8 support points.

[0017] Preferably, the fixed base is provided with a groove for the roller to roll horizontally.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The working principle of this utility model's X-bracing structure lifting base is as follows: The lifting motor drives the active lifting frame to move, and the active swing arm tube rotates around the first circular hole, driving the bed frame connecting tube to move. The roller at one end of the bed frame connecting tube moves horizontally along the slide groove on the fixed base, while the bed frame connecting piece at the other end moves vertically. Similarly, the driven lifting frame, driven by the synchronous tube, has its driven swing arm tube rotate around the second circular hole, driving the bed frame connecting tube to move. The bed frame connecting piece is fixedly connected to the electric bed frame, and the first roller group and the second roller group roll at the bottom of the electric bed frame, pushing the electric bed frame to move vertically.

[0020] This invention, based on an X-bracing structure, develops and designs a lifting base adapted for electric beds. During movement, it only shifts vertically, making it suitable for various usage scenarios. Furthermore, the X-bracing structure is stable and not easily deformed under load. With eight support points for electric beds, it is more stable than a swing arm structure. This vertically lifting base is compatible with various types of electric beds, meeting diverse usage needs. Simultaneously, this invention features a simplified structure, reducing the thickness of the lifting base and decreasing the packaging volume and weight of the electric bed, facilitating transportation and handling.

[0046] In a further preferred embodiment, the driven swing arm tube 31 is provided with a second round hole 32, and the fixed base 1 and the driven lifting frame 3 are hinged by inserting bolts into the second round hole 32.

[0047] In a further preferred embodiment, a bed frame connector 52 is provided at the end of the bed frame connecting tube 5 away from the roller 51, and the bed frame connector 52 is fixedly connected to the electric bed frame 7.

[0048] In a further preferred embodiment, a motor mounting horizontal tube 11 is installed on the fixed base 1, and the lifting motor 4 is connected to the motor mounting horizontal tube 11.

[0049] Further preferred, the X-bracing is provided in 4 sets.

[0050] In a further optimized configuration, each X-bracing forms two support points at its top, and the four sets of X-bracing form a total of eight support points.

[0051] More preferably, the fixed base 1 is provided with a groove 12 for the roller 51 to roll horizontally.

[0052] Please refer to the reference. Figure 6 The working principle of the X-bracing structure lifting base of this utility model is as follows: the lifting motor 4 drives the active lifting frame 2 to move, the active swing arm tube 21 rotates around the first circular hole 22, driving the bed frame connecting tube 5 to move. The roller 51 at one end of the bed frame connecting tube 5 moves horizontally along the sliding groove 12 on the fixed base 1, and the bed frame connecting piece 52 at the other end moves vertically. Similarly, the driven lifting frame 3, driven by the synchronous tube 6, has the driven swing arm tube 31 rotate around the second circular hole 32, driving the bed frame connecting tube 5 to move. The bed frame connecting piece 52 is fixedly connected to the electric bed frame 7, and the first roller group 211 and the second roller group 311 roll at the bottom of the electric bed frame 7, pushing the electric bed frame 7 to move vertically.

[0053] The lifting motor 4 starts, driving the active lifting frame 2 to move. The active lifting frame 2 drives the active swing arm tube 21 to rotate around the first circular hole 22. At the same time, the active lifting frame 2 also drives the bed frame connecting tube 5 to move. The movement of the bed frame connecting tube 5 drives the roller 51 at one end to move horizontally along the slide groove 12 on the fixed base 1. At the same time, the bed frame connecting piece 52 at the other end of the bed frame connecting tube 5 moves vertically. Similarly, the driven lifting frame 3 moves under the drive of the synchronous tube 6. The driven lifting frame 3 drives the driven swing arm tube 31 to rotate around the second circular hole 32. At the same time, the driven lifting frame 3 also drives the bed frame connecting tube 5 to move. The bed frame connecting piece 52 is fixedly connected to the electric bed frame 7. The first roller group 211 and the second roller group 311 roll at the bottom of the electric bed frame 7, pushing the electric bed frame 7 to move vertically.

[0054] While ensuring the load-bearing capacity of the lifting base, this invention minimizes the initial height of the lifting base while increasing its height adjustment range. The highest and lowest lifting states are referenced... Figure 7 and Figure 8 This makes the technology of this utility model more widely applicable and adaptable to more application scenarios. At the same time, the X-bracing structure is stable and not easily deformed under load. The four sets of X-bracing structures provide eight support points for the electric bed frame 7, and the force on each support point is balanced. The load on the lifting base can be evenly distributed to each point, which greatly improves the stability of the electric bed frame 7.

[0055] Research revealed a strong demand for height-adjustable electric beds during production and sales. However, current electric beds with height-adjustable functions are primarily designed for medical and nursing use, unsuitable for home use. The research also found that existing swing-arm type height-adjustable bases, due to horizontal displacement, have poor compatibility with existing home furniture frames. Through continuous experimentation, this utility model was designed with an X-bracing structure, enabling vertical height adjustment. This design is compatible with various types of electric beds and meets diverse usage scenarios. Furthermore, the structure is simplified, the thickness of the height-adjustable base is reduced, decreasing the packaging volume and weight of the electric bed, facilitating transportation and handling.
