It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0015] The present invention discloses a combined concave 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 a first electric push rod 3 for driving the seat 2 to slide back and forth. The seat 2 includes a sitting and reclining frame 21 and a backrest frame 22 that can rotate and recline relative to the sitting and reclining frame 21. The backrest frame 22 can be driven by an electric push rod, and the specific installation method belongs to the common knowledge of those skilled in the art. In the embodiment of the present invention, a sliding frame 4 is provided on the base 1 and is guided to slide back and forth in the front-rear direction. At least two first hinge shafts 5 are provided on both the left and right sides of the sliding frame 4, and swing arms 6 that can swing relative to the sliding frame 4 are provided on each first hinge shaft 5. Part of the sitting and reclining frame 21 is located outside the swing arms 6. The swing arms 6 include a hinge end 61 hinged to the first hinge shaft 5 and a driving end 62 for driving the swing arms 6 to rotate along the hinge end 61. The sitting and reclining frame 21 located outside the swing arms 6 is hinged to the driving end 62 so that the sitting and reclining frame 21 is suspended on the sliding frame 4. A swing arm driving assembly 7 for acting on the driving end to drive the swing arms 6 to swing relative to each other is also provided on the sliding frame 4. The first electric push rod 3 is hinged to the base 1, and the output end of the first electric push rod 3 acts on the sliding frame 4. When in use, the first electric push rod 3 can drive the sliding frame 4 to slide back and forth, thereby driving the sitting and reclining frame 21 to slide back and forth. At the same time, when the swing arm driving assembly 7 drives the swing arms 6 to swing, since the sitting and reclining frame 21 is suspended on the sliding frame 4, the sitting and reclining frame 21 can be driven to swing relative to each other, enabling it to have an electric swing function, improving the product configuration function, meeting more consumer needs, adapting to more types of foot baths and usage places, and this method can move the center of the circle of the swing of the sitting and reclining frame 21 upward to make it perform a movement similar to a pendulum, that is, a concave swing action. This way of swinging is more stable, and the movement gives people a hypnotic feeling, promoting rest and relaxation, and can relieve anxiety and tension.

[0016] A fixing ear 8 extending to the position of the sliding frame 4 is provided on the sliding seat frame 21. A positioning pin 9 is inserted between the fixing ear 8 and the sliding frame 4, and the positioning pin 9 is detachably connected to the fixing ear 8. Since the seat-back frame 21 is suspended on the sliding frame 4, it is easily damaged during transportation, resulting in abnormal functions. By using the positioning pin 9 for positioning and fixing, the seat-back frame 21 can be prevented from swaying, making it more stable during transportation. The positioning pin 9 can be removed when assembling after transportation is completed.

[0017] At least two support rods 10 are provided on both the left and right sides of the bottom of the seat-back frame 21. The two support rods 10 are connected by a connecting rod 20, and a second hinge shaft 30 is provided at the bottom position of each swing arm 6 where the connecting rod 20 is located. The connecting rod is suspended on the swing arm 6 through the second hinge shaft 30, so that the seat-back frame 21 is suspended on the sliding frame 4 through the swing arm 6. Connecting the two support rods 10 through the connecting rod 20 can increase the structural stiffness, and at the same time, it is also convenient for hinged cooperation with the swing arm 6, enabling it to drive multiple swing arms to swing simultaneously with better stability.

[0018] The swing arm drive assembly 7 includes a drive motor 71 fixed on the sliding frame 4, a rotating shaft 72 rotatably provided 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 40. A worm 50 linked and cooperated with the worm gear 40 is provided on the output shaft of the drive motor 71. The cooperation of the worm and worm gear can increase the torque, making it convenient to drive the seat-back frame 21 to swing. Two groups of the eccentric blocks 73 are oppositely arranged. 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 blocks 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. By reversing the worm and worm gear, the eccentric blocks 73 on both sides can be driven to rotate simultaneously, and then the swing arms 6 can be driven to swing through the pull rods 74 at the same time, which can increase the synchronization rate and has better stability.

[0019] A guide rail 60 arranged in the front-back direction is provided on the base 1. A guide block 70 is provided on the sliding frame 4 at the position of the guide rail 60, and balls are also provided between the guide rail 60 and the guide block 70. Through the cooperation of the guide rail 60 and the guide block 70, the sliding frame 4 can be driven to slide stably, preventing it from shifting left and right.

[0020] Armrest frames 80 are rotatably provided on both the left and right sides of the seat-back frame 21.
