Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a combined convex swing seat mechanism based on a slide rail. Background Technology

[0002] Most foot massage chairs on the market currently consist of a fixed frame and a movable frame, connected by a slide rail and driven by an electric cylinder to move the chair forward and backward. The backrest is mounted on the two pivots on the movable frame, with the lower ear seat connected to the electric cylinder. The electric cylinder drives the backrest to raise or lower. However, due to the limitations of the slide rail, the foot massage chair frame does not have a rocking function. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a combined convex swing seat mechanism based on a slide rail. On the basis of the existing front and back sliding and lifting back functions, it upgrades and adds electric swing function technology to improve the product configuration functions, meet more consumer needs, and adapt to more types of foot baths and places of use.

[0004] This utility model discloses a combined convex swing seat mechanism based on a slide rail, including a base, a seat that can slide back and forth relative to the base, and an electric actuator for driving the seat to slide back and forth. The seat includes a backrest and a backrest that can rotate and recline relative to the backrest. The base is provided with a sliding frame that guides and slides in the front-back direction. The sliding frame is characterized in that: at least two hinge shafts are provided on both the left and right sides of the sliding frame, and each hinge shaft is provided with a swing arm that can swing relative to the sliding frame. Each swing arm is provided with a movable end, a hinge end, and a driving end from top to bottom. The hinge end is hinged to the hinge shaft to form a rocker structure, and the movable end is hinged and supported on the backrest. The sliding frame is also provided with a swing arm driving assembly for driving the driving end to swing.

[0005] Using the above technical solution, the sliding frame can be moved back and forth by an electric actuator, while the backrest can be moved by a separate electric actuator. The installation method is conventional. The seat and backrest can be moved back and forth simultaneously by connecting the hinge shaft and swing arm. When the swing arm drive assembly drives the drive end to swing, the movable end will swing relative to it. Because the movable end is hinged and supported on the seat and backrest, the entire seat and backrest will be suspended in the air, causing it to swing along an arc trajectory, i.e., to sway. This action gives the user a roller coaster feeling, making people excited and joyful, and has a certain tension and contraction effect on the muscles, thus helping to promote gastrointestinal motility and digestion. Adding a swing function to the existing foot bath chair technology that allows for back and forth movement and lifting / lowering the backrest improves the product's configuration and functions, meets more consumer needs, and is suitable for more types of foot baths and usage locations.

[0006] A further feature of this invention is that the seat frame is provided with a fixing ear extending to the sliding frame position, and a positioning pin is provided between the fixing ear and the sliding frame, and the positioning pin is detachably connected to the fixing ear.

[0007] By adopting the above technical solution, since the seat and sliding frames are layered and easily damaged during transportation, positioning pins are used to pass through the fixing ears and sliding frames for positioning, which can make the transportation more stable and prevent swaying later. After transportation is completed, the positioning pins can be pulled out.

[0008] A further feature of this invention is as follows: the swing arm drive assembly includes a drive motor fixed on the sliding frame, a rotating shaft rotatably mounted on the sliding frame, an eccentric block rotating synchronously with the rotating shaft, and a pull rod that is linked with the eccentric block. The rotating shaft is horizontally mounted on the sliding frame and fitted with a worm gear. The output shaft of the drive motor is provided with a worm gear that is linked with the worm gear. Two sets of eccentric blocks are arranged opposite each other. One set is located on the left side of the rotating shaft and is linked with the left swing arm via the pull rod. The other set of eccentric blocks is located on the right side of the rotating shaft and is linked with the right swing arm via the pull rod.

[0009] Using the above technical solution, when in use, the drive motor can drive the worm gear to rotate, which in turn drives the worm wheel to rotate, causing the rotating shaft to rotate. The rotating shaft can drive the eccentric blocks on both sides to rotate, achieving eccentric motion. The pull rod can drive the drive end to swing, which in turn drives the movable end to swing, thereby causing the seat frame to sway. Furthermore, a single drive motor can drive the swing arms on both sides to swing, resulting in a high synchronization rate and good stability.

[0010] A further feature of this invention is that the base is provided with a guide rail arranged in the front-to-back direction, the sliding frame is provided with a guide block located at the guide rail position, and a ball bearing is provided between the guide rail and the guide block.

[0011] By adopting the above technical solution, the sliding frame can be guided and slid, and the ball bearings can reduce frictional resistance, making it more convenient to drive.

[0012] A further feature of this invention is that the driving ends of the swing arms on the same side are connected by a connecting rod to form a linkage structure, and the end of the pull rod that cooperates with the swing arm is hinged to the connecting rod.

[0013] Using the above technical solution, the connecting rod can drive the swing arm on the same side to move simultaneously, with high synchronization rate and good stability.

[0014] A further feature of this invention is that armrests are rotatably mounted on the left and right sides of the seat frame, and tabletops that can be flipped open and folded up are mounted on the armrests.

[0015] Using the above technical solution, the rotation of the handrail makes it easy for users to get up or sit down, and personal belongings can be placed on the table. When not in use, the table can be flipped up for storage without obstructing pedestrians.

[0016] A further feature of this invention is that the backrest frame is also provided with a walking guide rail, on which a massage mechanism is mounted, and the armrest frame is also provided with a first control switch for controlling the operation of the massage mechanism.

[0017] Using the above technical solution, the walking guide rail facilitates the movement of the massage mechanism, and the massage mechanism enables the massage function. The first control switch facilitates the control of the massage mechanism's operation.

[0018] Further features of this invention: The seat frame is also equipped with a heating pad and a vibration massage mechanism, and the armrest frame is also equipped with a second control switch for controlling the operation of the heating pad and the vibration massage mechanism.

[0019] By adopting the above technical solution, the therapeutic effects of vibration massage and hot compress can be increased, and the second control switch is placed on the armrest frame, making it more convenient to control. Attached Figure Description

[0026] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0027] 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.

[0028] This utility model discloses a combined convex 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 an 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 reclining of the backrest 22 is a conventional technical means and not the main utility model point of this application. Specifically, it can be driven by a hinge and an electric actuator, which will not be described in detail here. The base 1 is provided with a sliding frame 4 that guides and slides in the front and back direction. In the embodiments of this utility model... The sliding frame 4 is provided with at least two hinge shafts 5 on both the left and right sides. The multiple hinge shafts 5 make it more stable during use and prevent it from shaking. Each hinge shaft 5 is provided with a swing arm 6 that can swing relative to the sliding frame 4. Each swing arm 6 is provided with a movable end 61, a hinge end 62 and a drive end 63 from top to bottom. The hinge end 62 is hinged to the hinge shaft 5 to form a rocker structure. The movable end 61 is hinged to and supported on the seat frame 21, so that the entire seat frame can float. The sliding frame 4 is also provided with a swing arm drive assembly 7 for driving the drive end 63 to swing.

[0029] Using the above technical solution, during use, the electric push rod 3 can drive the sliding frame 4 to slide back and forth as a whole. At this time, the seat and backrest frame 21 can be driven to slide back and forth simultaneously through the hinge shaft 5, swing arm 6, etc. When the swing arm drive assembly 7 drives the drive end 63 to swing, the movable end 61 will swing relative to it. Because the movable end 61 is hinged and supported on the seat and backrest frame 21, it will suspend the entire seat and backrest frame 21 in the air and make it swing along an arc trajectory, that is, perform a convex swing. This action gives the user a roller coaster feeling, making people excited and joyful, and has a certain tension and contraction effect on the muscles. Therefore, it helps the stomach and intestines to move and digest. On the existing foot bath chair technology with back and forth movement and lifting and tilting back, the addition of the swing function improves the product configuration function, meets more consumer needs, and is suitable for more types of foot bath basins and places of use.

[0030] The seat frame 21 is provided with a fixed lug 8 extending to the sliding frame 4. A positioning pin 9 passes through the fixed lug 8 and the sliding frame 4, and the positioning pin 9 is detachably connected to the fixed lug 8. Because the seat frame 21 and the sliding frame 4 are layered, they are easily damaged during transportation. By positioning the fixed lug 8 and the sliding frame 4 through the positioning pin 9, the stability during transportation can be improved, preventing swaying in the later stages. After transportation, the positioning pin 9 can be pulled out.

[0031] 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 10. The output shaft of the drive motor 71 is provided with a worm 20 linked with the worm gear 10. Two sets of eccentric blocks 73 are 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 left side of the rotating shaft 72. The right side of shaft 72 is linked to the right swing arm 6 via tie rod 74. In use, the drive motor 71 drives the worm gear 20 to rotate, which in turn drives the worm wheel 10 to rotate, causing the rotating shaft 72 to rotate. The rotating shaft 72 can drive the eccentric blocks 73 on both sides to rotate, achieving eccentric motion. The tie rod 74 can drive the drive end 63 to swing, which in turn drives the movable end 61 to swing, thereby causing the seat frame 21 to swing. Furthermore, the drive motor 71 can drive the swing arms 6 on both sides to swing, resulting in a high synchronization rate and good stability.

[0032] The base 1 is provided with a guide rail 30 arranged in the front-to-back direction. The sliding frame 4 is provided with a guide block 40 located at the guide rail 30. A ball bearing (not shown in the figure) is also provided between the guide rail 30 and the guide block 40, so that the sliding frame 4 can be guided and slid. The ball bearing can reduce frictional resistance and make it more convenient to drive.

[0033] The drive end of the swing arm 6 on the same side is connected by the connecting rod 50 to form a linkage structure. The end of the pull rod 74 that cooperates with the swing arm 6 is hinged on the connecting rod 50. The connecting rod 50 can drive the swing arm 6 on the same side to move simultaneously, with high synchronization rate and good stability.

[0034] The seat frame 21 is provided with armrests 60 on its left and right sides. The armrests 60 are provided with tables 70 that can be flipped open and folded up. The rotation of the armrests 60 makes it easy for users to get up or sit down. Personal items can be placed on the tables 70. When not in use, the tables 70 can be flipped up and stored without obstructing pedestrians.

[0035] The backrest 22 is also provided with a walking guide rail 80, on which a massage mechanism 90 is provided. The armrest 60 is also provided with a first control switch for controlling the operation of the massage mechanism 90. The walking guide rail 80 facilitates the movement of the massage mechanism 90, and the massage mechanism 90 enables the massage function.
