However, due to the limitation of the front and back sliding guide rails, the seat frame of the foot bath massage chair does not have a swinging function. Summary of the Invention

[0003] Objective of the present invention: In order to overcome the defects of the prior art, the present invention provides a combined convex swing seat frame mechanism based on a slide rail. On the basis of the existing front and back sliding and raising and reclining back functions, an electric swinging function technology is upgraded and added to improve the product configuration function, meet more consumer needs, and adapt to more types of foot bath basins and usage places.

[0004] The present invention discloses a combined convex swing seat frame mechanism based on a slide rail, which includes a base, a seat that can slide back and forth relative to the base, and an electric push rod for driving the seat to slide back and forth. The seat includes a sitting and backrest frame and a backrest frame that can rotate and recline relative to the sitting and backrest frame. A sliding frame that guides and slides in the front and back directions is provided on the base. The characteristics are as follows: At least two hinge shafts are provided on both the left and right sides of the sliding frame, and swing arms that can swing relative to the sliding frame are provided on each hinge shaft. Each swing arm is sequentially provided with a movable end, a hinge end, and a driving end from top to bottom. The hinge end is hinged on the hinge shaft to form a seesaw structure. The movable end is hinged and supported on the sitting and backrest frame. A swing arm driving component for driving the driving end to swing is also provided on the sliding frame.

[0005] Adopting the above technical solution, during use, the electric push rod can drive the entire sliding frame to slide back and forth, and the backrest frame can be driven by a separate electric push rod. The specific installation method belongs to conventional technical means. At this time, the sitting and backrest frame can be driven to slide back and forth simultaneously through connections such as hinge shafts and swing arms. And when the swing arm driving component drives the driving end to swing, the movable end will swing relatively. Because the movable end is hinged and supported on the sitting and backrest frame, the entire sitting and backrest frame will be suspended and swing along an arc trajectory, that is, perform a convex swing. This action gives the user a feeling of a roller coaster, making people excited and happy, and has a certain effect of tense contraction on the muscles. Therefore, it helps the peristalsis and digestion of the stomach and intestines. On the basis of the existing foot bath chair technology of front and back movement and raising and reclining the back, a swinging function is added to improve the product configuration function, meet more consumer needs, and adapt to more types of foot bath basins and usage places.

[0022] The present invention discloses a combined convex swing seat frame mechanism based on a slide rail, which includes a base 1, a seat 2 that can slide back and forth relative to the base 1, and an electric push rod 3 for driving the seat 2 to slide back and forth. The seat 2 includes a seat and backrest frame 21 and a backrest frame 22 that can rotate and recline relative to the seat and backrest frame 21. The reclining of the backrest frame 22 belongs to conventional technical means and is not the main inventive point of this application. Specifically, it can be driven by hinges and electric push rods, and will not be introduced in detail herein. A sliding frame 4 is provided on the base 1 and is guided to slide back and forth in the front-rear direction. In the embodiment of the present invention, at least two hinge shafts 5 are provided on both the left and right sides of the sliding frame 4. The provision of multiple hinge shafts 5 makes it more stable during use and will not shake. A swing arm 6 that can swing relative to the sliding frame 4 is provided on each hinge shaft 5. An active end 61, a hinge end 62, and a driving end 63 are sequentially provided on each swing arm 6 from top to bottom. The hinge end 62 is hinged on the hinge shaft 5 to form a seesaw structure. The active end 61 is hinged and supported on the seat and backrest frame 21, enabling the entire seat and backrest frame to float. A swing arm driving assembly 7 for driving the driving end 63 to swing is further provided on the sliding frame 4.

[0023] With the above technical solution, during use, the electric push rod 3 can drive the entire sliding frame 4 to slide back and forth. At this time, the seat and backrest frame 21 can be driven to slide back and forth simultaneously through connections such as the hinge shaft 5 and the swing arm 6. And when the swing arm driving assembly 7 drives the driving end 63 to swing, the active end 61 will swing relatively. Since the active end 61 is hinged and supported on the seat and backrest frame 21, the entire seat and backrest frame 21 will be suspended and swing along an arc trajectory, that is, perform a convex swing. This action gives the user a feeling of a roller coaster, making people excited and happy, and has a certain effect of tense contraction on the muscles. Therefore, it helps with gastrointestinal peristalsis and digestion. On the basis of the existing foot bath chair technology with front-back movement and backrest lifting and reclining, a swinging function is added to improve the product configuration function, meet more consumer needs, and adapt to more types of foot bath basins and usage places.

[0024] A fixed ear 8 extending to the position of the sliding frame 4 is provided on the seat and backrest frame 21. A positioning pin 9 is passed through between the fixed ear 8 and the sliding frame 4, and the positioning pin 9 is detachably connected to the fixed ear 8. Because the seat and backrest frame 21 and the sliding frame 4 are layered, they are easily damaged during handling. By positioning with the positioning pin 9 passing through the fixed ear 8 and the sliding frame 4, it can be more stable during handling and prevent affecting the swing later. After handling, the positioning pin 9 can be pulled out.

[0025] The swing arm driving assembly 7 includes a driving motor 71 fixed on the sliding frame 4, a rotating shaft 72 rotatably arranged on the sliding frame 4, an eccentric block 73 synchronously rotating with the rotating shaft 72, and a pull rod 74 linked and cooperated with the eccentric block 73. The rotating shaft 72 is horizontally arranged on the sliding frame 4 and is sleeved with a worm gear 10. A worm 20 linked and cooperated with the worm gear 10 is arranged on the output shaft of the driving motor 71. There are two groups of eccentric blocks 73 arranged oppositely. One group is arranged on the left side of the rotating shaft 72 and is linked and cooperated with the left swing arm 6 through the pull rod 74. The other group of the eccentric block 73 is arranged on the right side of the rotating shaft 72 and is linked and cooperated with the right swing arm 6 through the pull rod 74. During use, the driving motor 71 works to drive the worm 20 to rotate, and at the same time drives the worm gear 10 to rotate, so that the rotating shaft 72 rotates. The rotating shaft 72 can drive the eccentric blocks 73 on both sides to rotate to achieve eccentric motion, and the driving end 63 can be driven to swing through the pull rod 74, so that the movable end 61 can be driven to swing, thereby driving the seat-back frame 21 to swing. Moreover, one driving motor 71 can drive the swing arms 6 on both sides to swing, and its synchronization rate is relatively high and the stability is good.

[0026] A guide rail 30 arranged in the front-back direction is provided on the base 1. A guide block 40 is arranged on the sliding frame 4 at the position of the guide rail 30. Moreover, balls (not shown in the figure) are provided between the guide rail 30 and the guide block 40, so that the sliding frame 4 can be guided and slid, and the friction resistance can be reduced through the balls, making it more convenient during driving.

[0027] The driving ends of the swing arms 6 on the same side are connected through a connecting rod 50 to form a linkage structure. One end of the pull rod 74 cooperating with the swing arm 6 is hinged on the connecting rod 50. The connecting rod 50 can drive the swing arms 6 on the same side to move simultaneously, and its synchronization rate is high and the stability is good.

[0028] Armrest frames 60 are rotatably arranged on the left and right sides of the seat-back frame 21. A table board 70 that can be relatively turned out and turned in is arranged on the armrest frames 60. The rotation of the armrest frames 60 is convenient for the user to get up or sit down. Moreover, personal items can be placed through the table board 70, and when not in use, the table board 70 is turned over and stored without hindering pedestrians from walking.
