Description

Technical Field

[0001] This utility model relates to the field of electric bed frame technology, and in particular to an electric bed frame. Background Technology

[0002] Bed frames, as common furniture for placing mattresses, have traditionally had relatively simple functions and lacked height adjustment features. As users' demands for the bed experience continue to increase, adjustable bed frames with segmented height adjustment have emerged, aiming to allow users to flexibly adjust the bed height according to their own needs.

[0003] To further enhance bed frame comfort, numerous bed frame products with lifting functions have emerged on the market. For example, Chinese Utility Model Patent Publication No. CN212307360U discloses a lifting structure for a lifting bed frame. This structure mainly includes an outer frame, a front lifting frame, and a rear lifting frame. The front lifting frame is installed at the front end of the outer frame, and its rear end is rotatably connected to the outer frame. The outer frame is equipped with a first electric push rod for lifting the front end of the front lifting frame. The rear lifting frame is installed at the rear end of the outer frame and consists of a front frame body and a rear frame body. The rear end of the front frame body is rotatably connected to the front end of the rear frame body, and the front end of the front frame body is rotatably connected to the outer frame. A second electric push rod is provided on the outer frame, and its push rod is connected to the rear end of the rear frame body. The segmented lifting of the bed frame is achieved through the two electric push rods.

[0004] While the existing electric bed frames described above can raise and lower the back and leg support frames via actuators, they present several problems in practical use. For example, when the bed frame is in a flat position, unevenness may exist between the support frames, reducing user comfort and potentially affecting the structural stability of the bed frame. Furthermore, after prolonged use, wear and tear between components in existing electric bed frames can lead to a decrease in the flatness and stability of the bed frame. Therefore, there is a need for an electric bed frame that can effectively solve these problems. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides an electric bed frame.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] An electric bed frame includes a central support frame, on which a back support frame and a leg support frame are respectively hinged at two opposite ends, and a fixing component is provided below the central support frame;

[0008] One end of the fixing member is hinged to the back support frame via a first driver and drives the back support frame to rise and fall; the other end of the fixing member is hinged to the leg support frame via a second driver and drives the leg support frame to rise and fall.

[0009] A horizontal limiting component is fixedly connected below the central support. When the bed frame is laid flat, the central support, the back support frame, and the leg support frame are connected in a straight line and overlap the upper side of the horizontal limiting component. The horizontal limiting component limits the lower side of the central support, the back support frame, and the leg support frame to ensure that the three components are coplanar and level.

[0010] Preferably, the horizontal limiting component includes a limiting rod, which is fixedly connected to the lower side of the central support.

[0013] Preferably, the leg support frame includes an active frame and a passive frame, the central support is hinged to the active frame and drives the active frame to rise and fall through the second driver, and the active frame is hinged to the passive frame and drives the passive frame to rise and fall.

[0014] The second support member includes a first tube leg located below the active frame and a second tube leg located below the passive frame. When the bed frame is laid flat, the lower surfaces of the first tube leg and the second tube leg are in contact with the upper surface of the limiting rod to form a contact support.

Detailed Implementation

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] like Figures 1 to 5 As shown, an electric bed frame includes a central support 1, with a back support frame 2 and a leg support frame 3 respectively hinged to the central support 1 on two opposite sides, and a fixing component 4 is provided below the central support 1.

[0034] One end of the fixed component 4 is hinged to the back support frame 2 via the first driver 5 and drives the back support frame 2 to rise and fall. The other end of the fixed component 4 is hinged to the leg support frame 3 via the second driver 6 and drives the leg support frame 3 to rise and fall.

[0035] A horizontal limiting component 7 is fixedly connected below the central support 1. When the bed frame is laid flat, the central support 1, the back support frame 2, and the leg support frame 3 are connected in a straight line and overlap the upper side of the horizontal limiting component 7. The horizontal limiting component 7 limits the lower side of the central support 1, the back support frame 2, and the leg support frame 3 to ensure that the three are coplanar and level.

[0036] Specifically, the horizontal limiting component 7 includes a limiting rod 701, which is fixedly connected to the lower side of the central support 1. When the bed frame is laid flat, the limiting rod 701 is arranged in parallel below the central support 1, the back support frame 2, and the leg support frame 3 to form contact support and limit the movement of the three components.

[0037] Furthermore, the limiting rod 701 is connected to the lower side of the central support 1 through the support frame 702, which serves to provide overall support. The back support frame 2 is provided with a first support member 8, and the leg support frame 3 is provided with a second support member 9. The first support member 8 and the second support member 9 correspond to the positions of the support frame 702.

[0038] When the bed frame is laid flat, the central support 1, back support frame 2, and leg support frame 3 are connected in a straight line and placed on the upper side of the support frame 702 and the limiting rod 701. The lower surfaces of the first support member 8 and the second support member 9 are in contact with the upper surface of the limiting rod 701 to form a contact support, so that the back support frame 2 and the leg support frame 3 can be well supported, ensuring that all parts of the bed frame are coplanar and level when laid flat, thereby improving the user's comfort and the stability of the bed frame.

[0039] The materials used for the support components can be varied. In addition to metal, wear-resistant and shock-absorbing engineering plastics (such as polyoxymethylene and nylon) can also be used to manufacture the support components. At the same time, special treatments can be applied to the surface of the support components, such as adding a rubber pad or covering them with microporous foam materials. This not only improves the contact stability with the limit rod and reduces wear, but also provides a certain degree of cushioning, reducing the vibration that the user may feel during the movement of the bed frame and improving the user experience.

[0040] Furthermore, the shape of the support components can be optimized according to actual needs. It can be designed not only as a columnar structure but also as an arc-shaped structure, increasing the contact area with the limiting rod and making the distribution more even, further improving support stability. Additionally, a cavity structure can be incorporated within the support components, filled with elastic materials (such as spring steel sheets, memory foam, etc.). When the bed frame is subjected to external impact or user activity, the elastic material can absorb some of the energy, playing a role in shock absorption and protecting the bed frame structure, thus extending the bed frame's lifespan.

[0041] Furthermore, the leg support frame 3 includes an active frame 301 and a passive frame 302. The central support 1 is hinged to the active frame 301 and drives the active frame 301 to rise and fall through the second driver 6. The active frame 301 is hinged to the passive frame 302 and drives the passive frame 302 to rise and fall.

[0042] The second support member 9 includes a first leg 901 located below the active frame 301 and a second leg 902 located below the passive frame 302. When the bed frame is laid flat, the lower surfaces of the first leg 901 and the second leg 902 are in contact with the upper surface of the limiting rod 701 to form a contact support. This split design makes the movement of the leg support frame 3 more flexible, better adaptable to the needs of different users, and improves the overall stability of the bed frame.

[0043] The passive frame 302 is also provided with a connecting component 10 connected to the support frame 702 below, and the movement of the passive frame 302 is limited by the connecting component 10.

[0044] The connecting assembly 10 includes a first connector 1001 fixedly disposed below the passive frame 302. The first connector 1001 is hinged to a rotating support arm 1002. One end of the rotating support arm 1002 is hinged to the first connector 1001, and the other end is hinged to the passive frame 302. When the second lifting bracket 601 is raised or lowered, the rotating support arm 1002 plays a supporting and traction role during the raising and lowering of the passive frame 302, preventing the passive frame 302 from swinging randomly and improving the stability and service life of the bed frame.

[0045] Furthermore, the first actuator 5 includes a first electric push rod 501, one end of which is pivotally connected to the fixed member 4 and the other end is pivotally connected to the lower side of the back support frame 2. The first electric push rod 501 extends and pushes the back support frame 2 to rotate relative to the central bracket 1.

[0046] The second actuator 6 includes a second electric push rod 601. One end of the second electric push rod 601 is pivotally connected to the fixed member 4, and the other end is pivotally connected to the lower side of the active frame 301. The second actuator 6 extends and pushes the active frame 301 to rotate relative to the central support 1.

[0047] Its fixing component 4 includes a connecting rod 401 and clamping plates 402 symmetrically arranged at both ends of the connecting rod 401. The clamping plates 402 at both ends of the connecting rod 401 are respectively connected to the base of the first electric push rod 501 and the second electric push rod 601. This symmetrical structure can evenly distribute the force of the first electric push rod 501 and the second electric push rod 601 during the extension process on the connecting rod 401. The clamping plates 402 at both ends counteract the force of the connecting rod 401 to maintain the overall stability of the bed frame.

[0048] Furthermore, the limiting rod 701 is provided with a connecting hole 11, through which the limiting rod 701 can be installed with a wooden board or bed board, which can be easily installed on different types of bed frames, improving versatility and applicability.

[0049] Furthermore, the back support frame 2 and the leg support frame 3 are provided with a clearance structure 12 for the first drive 5 and the second drive 6 motors and push rods to pass through. The clearance structure 12 provides sufficient space for the motors of the drive to prevent the motors from colliding or interfering with the support frame during the movement of the bed frame, thereby ensuring the normal operation of the drive and the stable operation of the bed frame.

[0050] In addition, the recessed structure 12 can also provide installation space for other devices. For example, a massage device can be embedded in the recessed structure 12 to further enhance functions such as massage and vibration. The massage head can be driven by a motor to perform massages of different intensities and modes, helping to relieve muscle fatigue and promote blood circulation. A heating function can also be added to provide users with a warm and comfortable experience in cold weather. The heating element can be made of carbon fiber heating pads, evenly distributed within the support frame of the bed frame, and the heating temperature can be adjusted by a controller.

[0051] like Figure 6 As shown, multiple horizontal limiting components 7 can be installed on the lower side of the central support 1, so that the horizontal limiting components 7 can be used not only on single beds but also on double beds, improving the versatility and applicability of the bed frame and meeting the needs of different users.

[0052] This utility model provides an electric bed frame. A horizontal limiting component 7 provides a reference plane when the bed frame is laid flat, ensuring that the central support 1, back support frame 2, and leg support frame 3 are connected in a straight line, are coplanar, and are level. This allows each support frame to accurately return to its initial position, ensuring a consistent starting point for each lifting and lowering operation. It also ensures a tight fit between all parts of the bed frame, preventing discomfort caused by unevenness between components and improving sleep quality. Simultaneously, it prevents the support frames from exceeding their design range during movement, avoiding damage due to excessive movement, extending the service life of each component, and reducing maintenance costs.

[0053] During long-term use, the horizontal limiting component 7 can reduce wear between components and extend the service life of the bed frame. It can effectively prevent structural instability caused by loose or deformed components.

[0054] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
