Description

Technical Field

[0001] This utility model relates to a massage sofa bed with a reclining linkage mechanism. Background Technology

[0002] Massage sofa beds are multifunctional furniture that combines the functions of a sofa and a bed, and also have massage and relaxation therapy effects. Traditional sofa beds with massage functions usually switch between sitting, semi-reclining and flat reclining modes through manual or multi-motor drive to meet the needs of users in different scenarios such as reading, watching movies or sleeping.

[0003] However, existing multifunctional sofas still have some shortcomings when changing modes. First, the interoperability between components in some products is poor, requiring users to adjust the backrest angle and leg rest height separately, making the operation cumbersome and inconsistent. Second, many automated massage sofa beds require multiple power sources to achieve complex movements, which not only increases the complexity of the mechanical structure and production costs but also raises the difficulty of later maintenance. In addition, during the unfolding process, the seat frame cannot move forward synchronously, resulting in a large gap between the backrest and the wall when the backrest folds back, wasting indoor space. Utility Model Content

[0004] In order to overcome the defects of the prior art, the present invention provides a massage sofa bed with a reclining linkage mechanism, which drives the sliding frame to move through a single drive mechanism, and uses a linkage assembly pivotally connected between the base, backrest frame and leg support frame to realize the synchronous linkage of the sliding frame moving forward, the backrest flipping and the leg support lifting.

[0005] This utility model discloses a massage sofa bed with a reclining linkage mechanism, comprising a base and a sliding frame connected to the base and capable of sliding back and forth relative to the base. The sliding frame includes a support frame, a seat frame, a backrest frame, and a leg support. The support frame and the base are slidably connected, and the seat frame is fixedly mounted on the support frame. The leg support and the backrest frame are rotatably connected to the front and rear ends of the seat frame, respectively. A linkage assembly is provided between the leg support, the backrest frame, and the base. The linkage assembly includes two first linkages pivotally connected between the two sides of the leg support and the two sides of the backrest frame, and two second linkages pivotally connected between the two sides of the backrest frame and the two sides of the base. A driving mechanism is provided between the seat frame and the base. The driving mechanism is used to drive the sliding frame to slide back and forth relative to the base. When the sliding frame slides forward and backward relative to the base, it can be linked by the second linkages to flip the backrest frame backward and forward accordingly. When the backrest frame flips backward and forward, it can be linked by the first linkages to flip the leg support frame upward and downward.

[0006] The drive mechanism of this utility model drives the sliding frame to slide back and forth relative to the base, while linking the backrest frame and leg support frame to rotate through the linkage assembly. This simplifies the internal structure of the product, reduces production costs, and the sliding frame can offset the rear space required for the backrest frame to rotate backward while moving forward, thus achieving a smaller wall clearance distance and improving the utilization rate of indoor space.

[0007] Furthermore, the drive mechanism is located inside the support frame. The drive mechanism is a flat-push electric actuator. The flat-push electric actuator includes a main unit located at the rear end, a guide rail connected to the front end of the main unit, and a slider movably mounted on the guide rail. The rear end of the flat-push electric actuator is located at the inner rear end of the support frame, and a connecting seat that cooperates with and is fixed to the slider is provided at the inner front end of the base.

[0008] Based on the above solution, the thrust of the flat-push electric linear actuator can be accurately and smoothly converted into the displacement of the sliding frame relative to the base, resulting in better transmission efficiency. Since the main unit and guide rail of the flat-push electric linear actuator are all set inside the support frame, they move synchronously with the sliding frame during operation, making the structure more compact and facilitating a smaller distance from the wall.

[0009] Furthermore, a control box is provided at the inner rear end of the support frame.

[0010] In the above solution, the control box, the main unit of the flat-push electric actuator, and the guide rail are all integrated into the support frame, which helps to reduce the wiring distance and avoid the pulling and wear of the cables during the movement.

[0011] Furthermore, the front two sides of the support frame are provided with first pulleys that contact the ground, the rear two sides of the support frame are provided with second pulleys, and the two sides of the base are respectively provided with sliding grooves that cooperate with the second pulleys to guide the movement.

[0012] In the above scheme, the frictional resistance with the ground is reduced by the first pulley at the front end, and the limiting and guiding of the second pulley at the rear end and the slide groove are coordinated to ensure that the sliding frame is subjected to balanced and smooth force during the displacement process, prevent the mechanism from swaying or jamming, and improve the support effect of the sliding frame.

[0013] Furthermore, the first connecting rod is disposed on the inner side of the support frame, and the lower end of the backrest frame is swayably disposed on the inner side of the support frame, with the rear end of the first connecting rod connected to the lower end of the backrest frame.

[0014] In the above scheme, a four-bar linkage mechanism can be formed between the backrest frame, the first link, the seat frame, and the leg support, and the flipping motion of the backrest frame is linked to the leg support to achieve the flipping.

[0015] Furthermore, the front end of the support frame is provided with a first baffle, and the first baffle has a first through groove for the first connecting rod to move.

[0016] In the above solution, the first baffle can serve as a shield, preventing foreign objects from entering the inside of the support frame, protecting the internal components, and improving the aesthetics when lying down.

[0017] Furthermore, the second connecting rod is connected between the rear side of the backrest frame and the rear end of the base. The upper end of the base is provided with a second baffle. The second baffle has a U-shaped structure, which includes a main body covering the rear end of the base and two extensions located on both sides of the upper end of the base. The main body is located behind the backrest frame, and the extensions are located on both sides of the seat frame. The main body of the second baffle is provided with a second through groove for the second connecting rod to move.

[0018] In the above solution, the second baffle can serve as a shield, preventing foreign objects from entering the inner side of the base through the gap between the base and the backrest frame when in a lying position, thus protecting the internal components and improving the aesthetics when lying down.

[0025] The structure of the massage sofa bed with reclining linkage mechanism in this embodiment of the utility model is as follows: Figure 1-6As shown, the device includes a base 1 and a sliding frame connected to the base 1 and slidable back and forth relative to the base 1. The sliding frame includes a support frame 21, a seat frame 22, a backrest frame 23, and a leg rest 24. The support frame 21 and the base 1 are slidably connected. The seat frame 22 is fixedly mounted on the support frame 21. The seat frame 22 is provided with an elastic support strip made of bent elastic metal wire to support the user's buttocks and improve comfort when sitting or lying down. The leg rest 24 and the backrest frame 23 are rotatably connected to the seat frame 22. The leg support 24 at the front and rear ends is used to support and lift the user's lower legs. The backrest 23 is equipped with guide rails along which the robotic arm can move to massage the user's lower back and other areas. A linkage assembly is provided between the leg support 24, the backrest 23, and the base 1. This linkage assembly includes two first linkages 31 pivotally connected between the two sides of the leg support 24 and the two sides of the backrest 23, and two second linkages 31 pivotally connected between the two sides of the backrest 23 and the two sides of the base 1. 2. The two first connecting rods 31 and the two second connecting rods 32 are symmetrically arranged. A driving mechanism is provided between the seat frame 22 and the base 1. The driving mechanism is used to drive the sliding frame to slide back and forth relative to the base 1. When the sliding frame slides forward and backward relative to the base 1, it can be linked by the second connecting rod 32 to flip the backrest frame 23 backward and forward respectively. When the backrest frame 23 flips backward and forward, it can be linked by the first connecting rod 31 to flip the leg support 24 upward and downward. That is, when the driving mechanism drives the sliding frame to slide forward relative to the base 1, since one end of the second connecting rod 32 is restricted, the other end of the second connecting rod 32 will pull the backrest frame 23 to flip backward. When the backrest frame 23 flips backward, it will drive the leg support 24 to flip upward through the first connecting rod 31, and the massage sofa bed will switch from sofa mode to bed mode, so that the user can lie down and rest. When the driving mechanism drives the sliding frame to slide backward, it will drive the backrest frame 23 to flip forward and drive the leg support 24 to flip downward, so that the massage sofa bed will switch from bed mode to sofa mode.

[0026] The drive mechanism of this utility model drives the sliding frame to slide back and forth relative to the base 1, while linking the backrest frame 23 and leg support frame 24 to rotate through the linkage assembly. This simplifies the internal structure of the product and reduces production costs. While the sliding frame moves forward, it can offset the rear space required for the backrest frame 23 to rotate backward, achieving a smaller distance from the wall. The massage sofa bed can be placed close to the wall, improving the utilization rate of indoor space.

[0027] The drive mechanism is located inside the support frame 21. The drive mechanism is a flat-push electric actuator 4. The flat-push electric actuator 4 includes a main unit 41 located at the rear end, a guide rail 42 connected to the front end of the main unit 41, and a slider 43 movably mounted on the guide rail 42. The flat-push electric actuator 4 is a mature product on the market, and its working principle is a known technology. The rear end of the flat-push electric actuator 4 is located at the inner rear end of the support frame 21, and a connecting seat 11 is provided at the inner front end of the base 1 to cooperate with and fix the slider 43.

[0028] When the flat-push electric actuator 4 is working, it can drive the slider 43 to move back and forth along the guide rail 42. The thrust of the flat-push electric actuator 4 can be accurately and smoothly converted into the displacement of the sliding frame relative to the base 1, which has better transmission efficiency. Since the main unit 41, guide rail 42 and other components of the flat-push electric actuator 4 are all set in the support frame 21, they move synchronously with the sliding frame when working, making the structure more compact and conducive to achieving a smaller distance from the wall.

[0029] The control box 5 is located at the inner rear end of the support frame 21. The control box 5, the main unit 41 of the flat-push electric push rod 4, the guide rail 42, etc. are all integrated into the support frame 21. This helps to reduce the wiring distance, including the wiring distance between the main unit 41 and the massage mechanism on the other sliding frame and the control box 5, and avoids pulling and wear on the cables during the movement.

[0030] The support frame 21 has first pulleys 61 on both sides of its front end that are in contact with the ground, and second pulleys 62 on both sides of its rear end. The base 1 has corresponding grooves 63 on both sides that cooperate with the second pulleys 62 to guide the movement.

[0031] The first pulley 61 and the second pulley 62 can reduce the frictional resistance when in contact with the ground and the base 1 groove 63, ensure that the sliding frame is subjected to balanced and smooth force during displacement, prevent the mechanism from swaying or jamming, and improve the support effect on the sliding frame.

[0032] The first link 31 is disposed inside the support frame 21, and the lower end of the backrest frame 23 is swayably disposed inside the support frame 21. The rear end of the first link 31 is connected to the lower end of the backrest frame 23, forming a four-bar linkage between the backrest frame 23, the first link 31, the seat frame 22, and the leg support 24. The leg support 24 is flipped by the flipping motion of the backrest frame 23.

[0033] The front end of the support frame 21 is provided with a first baffle 71. The first baffle 71 has a first through groove 711 for the first connecting rod 31 to move. The first baffle 71 can block foreign objects from entering the inside of the support frame 21, protect the internal components of the support frame 21, and improve the aesthetics when lying down.

[0034] The second connecting rod 32 is connected between the rear side of the backrest frame 23 and the rear end of the base 1. The upper end of the base 1 is provided with a second baffle 72. The second baffle 72 has a U-shaped structure, which includes a main body covering the rear end of the base 1 and two extensions located on both sides of the upper end of the base 1. The main body is located behind the backrest frame 23, and the extensions are located on both sides of the seat frame 22. The main body of the second baffle 72 is provided with a second through groove 721 for the second connecting rod 32 to move. The second baffle 72 can play a blocking role. When lying down, it can prevent foreign objects from entering the inner side of the base 1 through the gap between the base 1 and the backrest frame 23, thus protecting the internal components and improving the aesthetics when lying down.

[0035] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
