Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and more specifically, to a grooved support plate airbag lumbar support mechanism. Background Technology

[0002] In daily life, for people who sit or stand for long periods, such as drivers, office workers, assembly line workers, and sales staff, their lower back and neck muscles are often deformed or develop lumbar muscle strain due to prolonged pressure in one direction. While massage chairs are becoming increasingly popular, they typically incorporate a massage mechanism to provide a massage function. However, the high manufacturing cost of these massage mechanisms makes them difficult to implement for the average person. Lumbar support airbags, on the other hand, provide inflatable support and are relatively inexpensive to produce. Therefore, they offer the option of providing necessary support for the body, such as the lower back and neck, when resting or sitting at work, making them a key focus of our design considerations. Utility Model Content

[0003] This utility model overcomes the shortcomings of the prior art and proposes a sliding support plate airbag lumbar support mechanism. Its structure is reasonably designed. By setting an airbag lumbar support on the support plate, the airbag lumbar support can be hidden or slid to the corresponding position of the waist, back or neck of the human body. At this time, the airbag lumbar support is inflated in an adjustable manner to achieve more comfortable support for the human body, as well as to adjust the restoration and correction of the curvature of the lumbar spine, and reduce lumbar pressure, and other health-beneficial effects.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A sliding support plate airbag lumbar support mechanism includes a frame, a guide rail on the frame, and a sliding groove on the guide rail. The sliding groove includes a straight section and a curved section connected to each other. The guide rail is provided with guide holes that are layered with the sliding groove and parallel to the straight section. The mechanism also includes a drive assembly, a rocker arm, a support plate in the sliding groove, and an airbag lumbar support fixed to the support plate. The rocker arm includes a guide end and a hinge end. The guide end is rotatably connected to a transmission shaft located in the guide hole. The transmission shaft is driven by the drive assembly and moves along the guide hole. The hinge end is rotatably connected to the support plate. The support plate and the airbag lumbar support are driven by the rocker arm and slide along the sliding groove.

[0005] By adopting the above technical solution, and by setting the slide rail with straight and curved sections, and by setting the swing arm, when the swing arm is driven by the drive shaft, the drive shaft moves along the guide hole. The swing arm can rotate the linear motion into curved motion, allowing the support plate and the airbag lumbar support to slide along the straight and curved sections of the slide rail. Furthermore, when the airbag lumbar support slides to the curved section, it is deflated, thus achieving better concealment. When the airbag lumbar support slides from the curved section to the straight section, it can slide to the corresponding position of the waist, back, or neck. At this time, the airbag lumbar support is adjusted to inflate, achieving a more comfortable support for the human body. This effectively alleviates fatigue and physical injury caused by long-term labor.

[0006] Preferably, a bushing is fixedly mounted on the drive shaft. The bushing has a fitting part, a protrusion located between the fitting part and the drive shaft and protruding from the end face of the fitting part, and a stepped surface located on one side of the fitting part. The guide end is rotatably fitted onto the fitting part and abuts against the stepped surface. A limiting sleeve is provided on the drive shaft and abuts against the protrusion. The rocker arm is located between the limiting sleeve and the stepped surface. The limiting sleeve is a nut with internal threads. An external thread is provided on the drive shaft corresponding to the position of the limiting sleeve. The limiting sleeve is threadedly connected to the drive shaft.

[0007] By adopting the above technical solution, the protrusion can slightly protrude from the end face of the sleeve, mainly abutting against the limiting sleeve. This not only avoids affecting the rotational fit between the guide end and the bushing, but also limits the large displacement of the rocker arm in the axial direction of the transmission shaft. Specifically, by using a nut for the limiting sleeve, the tightness of the pressure on the protrusion can be adjusted, thereby ensuring that the rocker arm can rotate smoothly relative to the bushing.

[0008] Preferably, there are multiple support plates, which are hinged together. Each support plate includes a connecting seat near one end of the slide groove. The connecting seat is provided with a guide post extending into the slide groove. The connecting seat has a receiving groove for accommodating the swing arm, and the hinged end is hinged in the receiving groove.

[0009] By adopting the above technical solution, the multiple support plates provide better support for the human body and make it easier to install larger airbag lumbar supports. Considering the need for the support plates 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. The connecting seat can be integrally injection molded with the support plate, or it can be a sheet metal part fixedly connected to the support plate, as long as the connecting seat has sufficient strength.

[0010] Preferably, the drive assembly includes a synchronous belt structure, a drive shaft for driving the synchronous belt structure, and a drive unit for driving the drive shaft, 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 is simple in design, the transmission is smooth, and the transmission belt is parallel to the guide hole, ensuring smooth and accurate movement of the transmission shaft within the guide hole and preventing friction between the transmission shaft and the guide hole due to incorrect transmission direction. The synchronous belt structure has two guide rails adapted to both sides of the frame. The two synchronous belt structures are connected by a drive shaft. The synchronous belt movement is achieved by rotating the drive shaft through a drive unit. Specifically, the drive unit can be a geared motor and pulley system, or other existing mature technologies capable of achieving forward and reverse rotation of the drive shaft can be used.

[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 provided on the fixed seat and a Hall sensor provided on the frame or 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. Specifically, the limiting component adopts a scheme using magnets and Hall sensors. Of course, a direct contact limiting scheme can also be used, such as a limiting block scheme with a buffer pad, etc. 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.

[0019] 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.

[0020] like Figure 1-14 As shown, a sliding support plate airbag lumbar support mechanism includes a frame 1, a guide rail 2 on the frame 1, and a sliding groove 24 on the guide rail 2. The sliding groove 24 includes a straight section 22 and a curved section 23 connected to each other. The guide rail 2 is provided with guide holes 25 that are arranged in layers with the sliding groove 24 and are parallel to the straight section 22. The mechanism also includes a drive assembly 4, a swing rod 5, a support plate 6 in the sliding groove 24, and an airbag lumbar support 8 fixed 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 transmission shaft 7 located in the guide hole 25. The transmission shaft 7 is driven by the drive assembly 4 and moves along the guide hole 25. The hinge end 52 is rotatably connected to the support plate 6. The support plate 6 and the airbag lumbar support 8 are driven by the swing rod 5 and slide along the sliding groove 24.

[0021] By adopting the above technical solution, the slide 24 is configured with a straight section 22 and a curved section 23, and a swing rod 5 is provided. When the swing rod 5 is driven by the drive shaft 7, the drive shaft 7 moves along the guide hole 25. The swing rod 5 can rotate the linear motion into a curved motion, allowing the support plate 6 and the airbag lumbar support 8 to slide along the straight and curved sections 23 of the slide 24. Furthermore, when the airbag lumbar support 8 slides to the curved section 23, it is deflated, thus achieving better concealment of the airbag lumbar support 8. When the airbag lumbar support 8 slides from the curved section 23 to the straight section 22, it can slide to the corresponding position of the waist, back, or neck. At this time, the airbag lumbar support 8 is adjusted to inflate, achieving more comfortable support for the human body. This can effectively alleviate fatigue and physical injury caused by long-term labor.

[0022] The transmission shaft 7 is fixedly fitted with a bushing 3. The bushing 3 has a fitting part 31, a protrusion 32 located between the fitting part 31 and the transmission shaft 7 and protruding from the end face of the fitting part 31, and a stepped surface 33 on one side of the fitting part 31. The guide end 51 is rotatably fitted onto the fitting part 31 and abuts against the stepped surface 33. The transmission shaft 7 is provided with a limiting sleeve 34 that abuts against the protrusion 32. The rocker arm 5 is located between the limiting sleeve 34 and the stepped surface 33. The limiting sleeve 34 is a nut with internal threads. The transmission shaft 7 has external threads corresponding to the position of the limiting sleeve 34. The limiting sleeve 34 is threadedly connected to the transmission shaft 7. The protrusion 32 can slightly protrude from the end face of the fitting part 31, mainly abutting against the limiting sleeve 34. While not affecting the rotational fit between the guide end 51 and the bushing 3, it can also limit the rocker arm 5 from having a large displacement in the axial direction of the transmission shaft 7. Specifically, by using a nut for the limiting sleeve 34, the tightness of the pressure against the protrusion 32 can be adjusted, thereby ensuring that the rocker arm 5 can rotate smoothly relative to the bushing 3.

[0023] Furthermore, multiple support plates 6 are provided, and the multiple support plates 6 are hinged together. Each support plate 6 includes a connecting seat 61 near one end of the slide groove 24. The connecting seat 61 is provided with a guide post 62 extending into the slide groove 24. The connecting seat 61 has a receiving groove 63 for accommodating the swing arm 5, and the hinged end 52 is hinged in the receiving groove 63. The arrangement of multiple support plates 6 provides better support for the human body and makes it easier to install a larger airbag lumbar support 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. The connecting seat 61 can be integrally injection molded with the support plate 6, or it can be a sheet metal part and fixedly connected to the support plate 6, as long as the connecting seat 61 can meet the requirements of having a certain strength.

[0024] Furthermore, the drive assembly 4 includes a synchronous belt structure 41, a drive shaft 45 driving the synchronous belt structure 41, and a drive unit 44 driving the drive shaft 45. The transmission belt 42 of the synchronous belt structure 41 is 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 smooth and accurate movement of the transmission shaft 7 within the guide hole 25, preventing friction between the transmission shaft 7 and the guide hole 25 due to incorrect transmission direction. The synchronous belt structure 41 has two guide rails 2 adapted to the sides of the frame 1. The two synchronous belt structures 41 are connected by the drive shaft 45. The synchronous belt movement is achieved by rotating the drive shaft 45 driven by the drive unit 44. Specifically, the drive unit 44 can employ a geared motor and pulleys, or other existing mature technologies capable of achieving forward and reverse rotation of the drive shaft 45.

[0025] 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 frame 1 or 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. 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.

[0026] 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.
