Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and more specifically, to an airbag seat adjustment mechanism with movable and tuckable functions. Background Technology

[0002] Massage sofas typically have grooves in the backrest to accommodate the massage mechanism. However, when a person sits on the sofa, the backrest sags, compromising the sofa's comfort. To improve both comfort and massage functionality, a support mechanism is needed to support the body when not massaging, enhancing the sofa's seating comfort. This mechanism needs to be concealed during massage operations. Utility Model Content

[0003] This invention overcomes the shortcomings of the prior art and proposes an airbag seat cushion adjustment mechanism with movable and retractable functions. Its structure is reasonably designed. By setting a support plate and a swing rod, the support plate and airbag can adjust and support the human body. Furthermore, the swing rod can drive the support plate to move into the curved part of the guide rail and hide it, thereby improving the seating feel and comfort of the sofa while also realizing the massage function.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An airbag seat adjustment mechanism with movable and retractable functions includes a guide rail with a straight section and a curved section, a slide groove on the guide rail extending from the straight section to the curved section, a drive assembly, a swing arm, and at least one support plate disposed in the slide groove. An airbag is disposed on the support plate. The swing arm includes a guide end and a hinge end. The guide end is rotatably connected to a drive shaft, which is driven by the drive assembly and moves along the straight section. The hinge end is rotatably connected to the support plate. The support plate and the airbag can be driven by the swing arm and slide along the slide groove to the curved section for concealment, or the support plate and the airbag can slide along the slide groove and move out from the curved section to support the human body. A guide hole is provided on the straight section, and the drive shaft is located in the guide hole and moves along the guide hole.

[0005] By adopting the above technical solution, the slide groove is used to guide the support plate, and the guide hole can be set on the straight section. Since the swing rod itself has a certain length, when the drive shaft is driven to move along the guide hole, the guide end of the swing rod is rotatably mounted on the drive shaft. Specifically, a bushing is fixed on the drive shaft, and the swing rod rotates and is sleeved on the bushing. The hinge end of the swing rod is rotatably mounted on the support plate. The swing rod can convert the linear motion of the drive shaft into curved motion, allowing the support plate to move along the slide groove on the curved section. Thus, by setting the swing rod, the support plate can move along the slide groove. When the support plate moves onto the slide groove of the curved section, it achieves the purpose of being hidden. When the support plate moves out of the curved section, specifically, it can move to the straight section or the connection between the straight and curved sections, thereby supporting the lower back. This achieves an effect that neither affects the massage nor the comfort. The airbags provide more comfortable support for the lower back. The airbags can be inflated and deflated to adjust their strength to suit the individual's needs. Furthermore, the airbags can be configured to inflate and deflate at a higher frequency to provide a massage effect. Specifically, when the support plate moves to the curved section for concealment, the airbags deflate for better hiding. Alternatively, the airbags can inflate when moving to the curved section, allowing them to adjust the seat cushion.

[0006] Preferably, there are multiple support plates, and the multiple support plates are hinged together.

[0007] By adopting the above technical solution, the arrangement of multiple support plates provides better support for the human body and makes it easier to install larger inflatable airbags. Considering that the support plates need to bend and move, the multiple support plates are hinged together, allowing each support plate to bend at a certain angle, thus ensuring that all support plates can enter or exit the bending section.

[0008] Preferably, the support plate includes a connecting seat near one end of the slide groove, a guide post extending into the slide groove is provided on the connecting seat, and a receiving groove for accommodating the swing arm is formed on the connecting seat, with the hinged end hinged in the receiving groove.

[0009] By adopting the above technical solution, the connecting seat can be integrally injection molded with the support plate, or it can be a sheet metal part and fixedly connected to the support plate, as long as the connecting seat can meet the requirement of having a certain strength.

[0010] Preferably, the drive assembly includes a synchronous belt structure, wherein the conveyor belt of the synchronous belt structure is arranged parallel to the guide hole.

[0011] By adopting the above technical solution, a synchronous belt structure is used for transmission. The structure design is simple, the transmission is smooth, and the transmission belt is set parallel to the guide hole to ensure that the transmission shaft moves smoothly and accurately in the guide hole and prevent friction between the transmission shaft and the guide hole due to incorrect transmission direction.

[0012] Preferably, the conveyor belt is provided with a fixed seat, which is fixedly connected to the drive shaft, and also includes a limiting component for limiting the movement distance of the fixed seat. The limiting component includes a magnet disposed on the fixed seat and a Hall sensor disposed on the guide rail.

[0013] By adopting the above technical solution, the fixed seat is fixedly installed on the transmission belt. As the transmission belt moves, the transmission shaft is fixed to the fixed seat, thereby driving the transmission shaft to move along the guide hole. The limiting component limits the movement stroke of the fixed seat to prevent the transmission shaft from moving excessively and causing collisions. Therefore, the position of the limiting component and the length of the guide hole need to be reasonably set to ensure that the support plate can be smoothly hidden and moved to provide support. Specifically, the limiting component adopts a scheme using magnets and Hall sensors. Of course, a direct contact limiting scheme, such as a limiting block scheme with a buffer pad, is also possible.

[0014] Preferably, the drive assembly further includes a drive unit and a drive shaft that drives the synchronous belt structure transmission, the drive shaft being driven by the drive unit.

[0015] By adopting the above technical solution, two synchronous belt structures are set to adapt to two guide rails. The two synchronous belt structures are connected by a drive shaft. The synchronous belt can be moved by driving the shaft to rotate through the drive unit. Specifically, the drive unit can adopt a geared motor and pulley scheme. Of course, other existing mature technologies that can realize forward and reverse rotation of the drive shaft can also be used. Attached Figure Description

In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] like Figure 1-13 As shown, an airbag seat adjustment mechanism with movable and retractable functions includes a guide rail 2 having a straight section 22 and a curved section 23. The guide rail 2 is provided with a slide groove 24 extending from the straight section 22 to the curved section 23. It also includes a drive assembly 4, a swing rod 5, and at least one support plate 6 disposed in the slide groove 24. An airbag 8 is disposed on the support plate 6. The swing rod 5 includes a guide end 51 and a hinge end 52. The guide end 51 is rotatably connected to a drive shaft 7. The drive shaft 7 is driven by the drive assembly 4 and moves along the straight section 22. The hinge end 52 is rotatably connected to the support plate 6. The support plate 6 and the airbag 8 can be driven by the swing rod 5 and slide along the slide groove 24 to the curved section 23 for concealment, or the support plate 6 and the airbag 8 can slide along the slide groove 24 and move out from the curved section 23 to support the human body. A guide hole 25 is provided on the straight section 22. The drive shaft 7 is located in the guide hole 25 and moves along the guide hole 25.

[0023] By adopting the above technical solution, the slide groove 24 is used to guide the support plate 6, and the guide hole 25 can be specifically set on the straight section 22. Since the rocker arm 5 itself has a certain length, when the transmission shaft 7 is driven to move along the guide hole 25, the guide end 51 of the rocker arm 5 is rotatably set on the transmission shaft 7. Specifically, a bushing is fixed on the transmission shaft 7, and the guide end 51 of the rocker arm 5 is rotatably sleeved on the bushing, while the hinge end 52 of the rocker arm 5 is rotatably set on the support plate 6. Through the rocker arm 5, the linear motion of the transmission shaft 7 can be converted into curved motion, so that the support plate 6 can move along the slide groove 24 on the curved section 23. In this way, by setting the rocker arm 5, the support plate 6 can move along the slide groove 24. When the support plate 6 moves to the slide groove 24 of the curved section 23, it will achieve the purpose of being hidden. When the support plate 6 moves out of the curved section 23, specifically, the support plate 6 can move onto the straight section 22, or to the connection point between the straight section 22 and the curved section 23, thereby supporting the lower back. This achieves an effect that neither affects the massage nor the comfort. The airbag 8 provides more comfortable support for the lower back. The airbag 8 can be inflated and deflated to adjust its strength to suit the body. Furthermore, the airbag 8 can be set to inflate and deflate at a higher frequency to provide a massage effect. Specifically, when the support plate 6 moves to the curved section for concealment, the airbag 8 deflates for better concealment. Alternatively, the airbag 8 can inflate when moving to the curved section, allowing it to adjust the seat cushion.

[0024] Furthermore, multiple support plates 6 are provided, and these support plates 6 are hinged together. The arrangement of multiple support plates 6 provides better support for the human body and makes it easier to install larger inflatable airbags 8. Considering that the support plates 6 need to bend and move, the multiple support plates 6 are hinged together, so that each support plate 6 can bend at a certain angle, thereby ensuring that multiple support plates 6 can enter or move out of the bending section 23.

[0025] Furthermore, the support plate 6 includes a connecting seat 61 near one end of the slide groove 24. The connecting seat 61 has a guide post 62 extending into the slide groove 24, and a receiving groove 63 is formed on the connecting seat 61 for accommodating the rocker arm 5. The hinged end 52 is hinged in the receiving groove 63. The connecting seat 61 can be integrally injection molded with the support plate 6, or it can be a sheet metal part fixedly connected to the support plate 6, as long as the connecting seat 61 has sufficient strength.

[0026] The drive assembly 4 includes a synchronous belt structure 41, with the transmission belt 42 of the synchronous belt structure 41 arranged parallel to the guide hole 25. Using the synchronous belt structure 41 for transmission results in a simple design, smooth transmission, and the parallel arrangement of the transmission belt with the guide hole 25 ensures the smooth and accurate movement of the drive shaft 7 within the guide hole 25, preventing friction between the drive shaft 7 and the guide hole 25 due to incorrect transmission direction.

[0027] Additionally, a fixed seat 43 is provided on the conveyor belt 42, which is fixedly connected to the drive shaft 7. A limiting component 9 is also included to restrict the movement distance of the fixed seat 43. The limiting component 9 includes a magnet 91 mounted on the fixed seat 43 and a Hall sensor 92 mounted on the guide rail 2. The fixed seat 43 is fixedly installed on the drive belt. As the drive belt moves, the drive shaft 7 is fixed to the fixed seat 43, thereby driving the drive shaft 7 to move along the guide hole 25. The limiting component 9 limits the movement of the fixed seat 43 to prevent the drive shaft 7 from moving excessively and causing a collision. Therefore, the position of the limiting component 9 and the length of the guide hole 25 need to be reasonably set to ensure that the support plate 6 can be smoothly hidden and moved to provide support. Specifically, the limiting component 9 uses a magnet 91 and a Hall sensor 92. Of course, a direct contact limiting solution, such as a limiting block with a buffer pad, can also be used.

[0028] Furthermore, the drive assembly 4 also includes a drive unit 44 and a drive shaft 45 that drives the synchronous belt structure 41. The drive shaft 45 is driven by the drive unit 44. Two synchronous belt structures 41 are provided to accommodate two guide rails 2. The two synchronous belt structures 41 are connected by the drive shaft 45. The synchronous belt can be moved by rotating the drive shaft 45 driven by the drive unit 44. Specifically, the drive unit 44 can adopt a geared motor and pulley scheme, or other existing mature technologies that can realize the forward and reverse rotation of the drive shaft 45 can be used.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
