[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] This utility model discloses a combined concave swing seat mechanism based on a slide rail, including a base 1, a seat 2 that can slide back and forth relative to the base 1, and a first electric actuator 3 for driving the seat 2 to slide back and forth. The seat 2 includes a backrest 21 and a backrest 22 that can rotate and recline relative to the backrest 21. The backrest 22 can be driven by the electric actuator. The specific installation method is common knowledge to those skilled in the art. In this utility model embodiment, the base 1 is provided with a sliding frame 4 that guides and slides in the front-back direction. At least two first hinge shafts 5 are provided on the left and right sides of the sliding frame 4. Each first hinge shaft 5 is provided with a swing arm 6 that can swing relative to the sliding frame 4. The backrest 21 is located outside the swing arm 6. The swing arm 6 includes a hinge end 61 that is hinged to the first hinge shaft 5 and a driving end 62 for driving the swing arm 6 to rotate along the hinge end 61. The backrest 21 located outside the swing arm 6 is hinged to the driving end 62. The seat frame 21 is suspended on the sliding frame 4. The sliding frame 4 is also equipped with a swing arm drive assembly 7 for driving the swing arm 6 to swing relative to each other on the drive end. The first electric actuator 3 is hinged on the base 1, and the output end of the first electric actuator 3 acts on the sliding frame 4. In use, the first electric actuator 3 can drive the sliding frame 4 to slide back and forth, which can drive the seat frame 21 to slide back and forth. At the same time, when the swing arm drive assembly 7 drives the swing arm 6 to swing, since the seat frame 21 is suspended on the sliding frame 4, it can drive the seat frame 21 to swing relative to each other, so that it has an electric swing function, improves the product configuration function, meets more consumer needs, and is suitable for more types of foot baths and places of use. In addition, this method can move the center of the swing of the seat frame 21 upward, so that it makes a pendulum-like motion, which is called a concave pendulum motion. The swing of this method is more stable, and the motion gives people a hypnotic feeling, promotes rest and relaxation, and can relieve anxiety and tension.

[0023] The sliding seat frame 21 is provided with a fixing lug 8 extending to the sliding frame 4. A positioning pin 9 passes through the fixing lug 8 and the sliding frame 4, and the positioning pin 9 is detachably connected to the fixing lug 8. Since the seat frame 21 is suspended on the sliding frame 4, it is easily damaged during transportation, which may lead to malfunction. The positioning pin 9 is used for positioning and fixing to prevent the seat frame 21 from swaying and to make it more stable during transportation. The positioning pin 9 can be removed when assembling after transportation.

[0024] At least two support rods 10 are provided on the left and right sides of the bottom of the seat frame 21. The two support rods 10 are connected by a connecting rod 20. The connecting rod 20 is provided with a second hinge shaft 30 at the bottom of each swing arm 6. The connecting rod is suspended on the swing arm 6 through the second hinge shaft 30, so that the seat 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 rigidity and facilitate the hinged cooperation with the swing arm 6, so that it can drive multiple swing arms to swing at the same time with better stability.

[0025] The swing arm drive assembly 7 includes a drive motor 71 fixed on the sliding frame 4, a rotating shaft 72 rotatably mounted on the sliding frame 4, an eccentric block 73 rotating synchronously with the rotating shaft 72, and a pull rod 74 linked with the eccentric block 73. The rotating shaft 72 is horizontally mounted on the sliding frame 4 and fitted with a worm gear 40. The output shaft of the drive motor 71 is equipped with a worm 50 linked with the worm gear 40. The worm gear and worm can increase torque, making it easier to drive the seat frame 21 to swing. There are two sets of eccentric blocks 73 arranged opposite each other. One set is located on the left side of the rotating shaft 72 and linked with the left swing arm 6 via the pull rod 74. The other set of eccentric blocks 73 is located on the right side of the rotating shaft 72 and linked with the right swing arm 6 via the pull rod 74. By reversing the direction of the worm gear and worm, the eccentric blocks 73 on both sides can be rotated simultaneously, so that the swing arm 6 can be driven to swing simultaneously via the pull rod 74, which can increase the synchronization rate and improve stability.

[0026] The base 1 is provided with a guide rail 60 arranged in the front-to-back direction. The sliding frame 4 is provided with a guide block 70 located at the guide rail 60. A ball bearing is also provided between the guide rail 60 and the guide block 70. The sliding frame 4 can be driven to slide stably by the cooperation of the guide rail 60 and the guide block 70 to prevent it from deviating to the left or right.

[0027] The seat frame 21 is provided with armrests 80 on its left and right sides. The armrests 80 are provided with tables 90 that can be flipped open and flipped closed. The tables 90 can be used to place some small items and can be stored by flipping. When not in use, they will not obstruct pedestrians.

[0028] The backrest 22 is also provided with a walking guide rail 100, and a massage mechanism 200 is provided on the walking guide rail 100. The armrest 80 is also provided with a first control switch for controlling the operation of the massage mechanism 200. The specific installation method of the walking guide rail 100 and the massage mechanism 200 is common knowledge to those skilled in the art, and will not be described in detail here. The massage mechanism 200 can increase the massage function of the back and waist.

[0029] The seat frame 21 is also equipped with a heating pad and a vibration massage mechanism (the vibration massage mechanism can be realized by a vibration motor, not shown in the figure). The armrest frame 80 is also equipped with a second control switch for controlling the operation of the heating pad and the vibration massage mechanism. The first control switch and the second control switch can be micro switches, touch switches, or of course, can be controlled by a mobile phone via Bluetooth or other modules.
