Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a relative motion support steel structure with lifting and rotation functions. Background Technology

[0002] The calf unit in a massage chair typically includes motorized rollers or airbags that simulate kneading, tapping, and squeezing motions from a human hand. These units automatically wrap around the user's calf to accommodate different leg shapes. The motorized rollers move along the contours of the calf, providing acupressure and massage effects, while the airbags inflate and deflate to simulate compression massage, promoting blood circulation and relieving muscle fatigue. Some high-end massage chairs may also include a heat therapy function to further enhance the relaxation effect.

[0003] Most massage chairs have a leg massage mechanism that can lift and massage the legs, allowing users to lie down for a massage. However, because the legs are embedded in the leg massage mechanism, it is difficult to get up, making these massage chairs unsuitable for the elderly, pregnant women, children, or people with arm injuries.

[0004] In order to control the calf massage mechanism and the foot massage mechanism to avoid each other, a support is needed for control. In the existing technology, the foot massage mechanism is directly moved to both sides to expose the middle part, so as to make it easier for the user to stand up. However, the middle position is limited after the mechanism is moved, and people are prone to tripping when standing, so there are still limitations. Summary of the Invention

[0005] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a relative motion support steel structure with lifting and rotation functions. It uses a driving component to drive the tilting frame to translate, lift and rotate, thereby releasing the space on one side in front of the lower leg frame. The released space is relatively large, which makes it easier for people to get up.

[0006] This utility model discloses a steel structure for a relative motion support with lifting and rotation functions, including a lower leg frame. The lower leg frame is characterized by a tilting frame and a tilting drive assembly for rotating the tilting frame to one side. The tilting drive assembly includes a guide shaft horizontally mounted on the lower leg frame, a bushing sliding on the guide shaft, a tie rod oscillating on the lower leg frame, a gear disk driving the tie rod to rotate, a rack driving the gear disk to rotate and rise, and a telescopic drive component driving the rack to extend and retract. The gear disk is suspended on and meshes with the rack. A hinge shaft is provided on one side of the lower leg frame. The gear disk is rotatably mounted on the hinge shaft and can slide axially relative to the hinge shaft. One end of the pull rod is mounted on the gear disk and rotates synchronously with it, while the other end is hinged to the tilting frame. The rack includes a first straight section, an inclined connecting section, and a second straight section. The gear disk can rise to the second straight section or fall to the first straight section via the inclined connecting section. The guide shaft includes a first guide section, an inclined guide section, and a second guide section. The bushing can rise to the second guide section or fall to the first guide section via the inclined guide section. The bottom of the bushing is provided with a mounting shaft. The tilting frame is hung on the mounting shaft and can rotate relative to the mounting shaft.

[0007] A further feature of this invention is that the gear disk includes a limiting plate and a gear disk. Two limiting plates are arranged at intervals along the vertical direction. A rack is inserted between the two limiting plates and meshes with the gear disk. The top limiting plate abuts against the top of the rack.

[0008] A further feature of this invention is that the pull rod is shaped like a figure 7 and is formed by two base rods and one drive rod. The two base rods are spaced apart in the vertical direction to form a clearance space. Two limiting plates are located within the clearance space, and each limiting plate is provided with an assembly groove corresponding to the position of the base rod. An opening is provided on one side of the assembly groove, and the base rod is located inside the assembly groove and extends out of the assembly groove from the opening on one side.

[0009] A further feature of this invention is that the bushing is also provided with a suspension roller, the suspension roller is rotatably mounted on the bushing, and the bushing is suspended on the guide shaft via the suspension roller.

[0010] Using the above technical solution, when in use, it is assembled onto a massage chair. The calf massage mechanism and foot massage mechanism are set on the flip frame. After the massage is finished, the telescopic drive extends, thereby driving the rack to extend. Because the rack meshes with the gear plate, it can drive the gear plate to rotate, thereby driving the pull rod to rotate relative to it. Because the flip frame is hung on the mounting shaft, and because of the guiding cooperation of the bushing and the guide shaft, the flip frame can simultaneously perform two actions: sliding and rotating. When the inclined connecting section of the rack meshes with the gear plate, the bushing is located at the inclined guide section position, and both rise at the same time, so that the flip frame can be raised normally without obstruction. This achieves movement in three directions: translation, flipping, and lifting, freeing up some space on the front side of the calf frame. The freed-up space is relatively large, making it easier for the elderly and pregnant women to stand, and also preventing tripping. It is more practical. Furthermore, using a single drive component to drive the flip frame to lift and simultaneously slide and rotate to one side has multiple benefits, simplifies the corresponding structure, and reduces drive costs.

[0021] This invention discloses a gear shaft driven roller type calf side-rotation clearance mechanism with lifting function, including a calf frame 1 for installation on a massage chair or massage sofa. In an embodiment of this invention, the calf frame 1 is provided with a flip frame 2 and a clearance drive assembly for driving the flip frame 2 to rotate to one side. The clearance drive assembly includes a guide shaft 3 horizontally arranged on the calf frame 1, a bushing 4 sliding on the guide shaft 3, a pull rod 5 swinging on the calf frame 1, a gear disk 7 driving the pull rod 5 to rotate, a rack 8 driving the gear disk 7 to rotate and rise, and a telescopic drive component 9 driving the rack 8 to extend and retract (the telescopic drive component 9 is preferably a cylinder, but can also be an electric cylinder or a telescopic motor). The gear disk 7 is suspended on and meshes with the rack 8. A hinge shaft 10 is provided on one side of the leg frame 1, and the gear disk 7 is rotatably sleeved on the hinge shaft 10 and can slide axially relative to the hinge shaft 10. One end of the pull rod 5 is provided on the gear disk 7 and rotates synchronously with it, and the other end is hinged on the tilting frame 2. The rack 8 includes a first straight section 81, an inclined connecting section 82 and a second straight section 83. The gear disk 7 can rise to the second straight section 83 or fall to the first straight section 81 via the inclined connecting section 82. The guide shaft 3 includes a first guide section 31, an inclined guide section 32 and a second guide section 33. The bushing 4 can rise to the second guide section 33 or fall to the first guide section 31 via the inclined guide section 32. The bottom of the bushing 4 is provided with a mounting shaft 20. The tilting frame 2 is hung on the mounting shaft 20 and can rotate relative to the mounting shaft 20.

[0022] Using the above technical solution, when in use, it is assembled onto a massage chair, and the calf massage mechanism and foot massage mechanism are placed on the flip frame 2 to provide massage for the user. After the massage is completed, the telescopic drive component 9 extends, thereby driving the rack 8 to extend. Since the rack 8 meshes with the gear disk 7, it can drive the gear disk 7 to rotate, thereby driving the pull rod 5 to rotate relative to it. Because the flip frame 2 is hung on the mounting shaft 20, and because of the guiding cooperation of the bushing 4 and the guide shaft 3, the flip frame 2 can simultaneously perform two actions: sliding and rotating. When the inclined connecting section 82 of the rack 8 engages with the gear disk 7... During engagement, the bushing 4 is located at the inclined guide section 32. Both rise simultaneously due to the inclined slope, allowing the tilting frame 2 to be raised normally without obstruction. This enables movement in three directions: translation, tilting, and lifting. It also releases some space in front of the lower leg frame 1, providing a relatively large space that makes it easier for the elderly and pregnant women to stand and prevents them from tripping. This enhances its practicality. Furthermore, a single drive unit can lift the tilting frame 2 and simultaneously slide and rotate it to one side, achieving multiple benefits in one go. This simplifies the corresponding structure and reduces drive costs.

[0023] The gear disk 7 includes a limiting plate 71 and a gear disk 72. Two limiting plates 71 are arranged at intervals along the vertical direction. The rack 8 is inserted between the two limiting plates 71 and meshes with the gear disk 72. The top limiting plate 71 abuts against the top of the rack 8. The two limiting plates 71 can prevent the rack 8 from dislodging and facilitate the rack 8 to drive the gear disk 7 to rise and fall as a whole, making the rack 8 more stable when it is engaged with the gear disk 72.

[0024] The pull rod 5 is shaped like a figure 7 and is formed by two base rods 51 and one drive rod 52. The two base rods 51 are spaced apart vertically to form a clearance space. Two limiting plates 71 are partially located within the clearance space, and each limiting plate 71 has an assembly groove 711 corresponding to the position of the base rod 51. An opening 712 is opened on one side of the assembly groove 711. The base rod is located in the assembly groove 711 and extends from the opening 712 on one side to the outside of the assembly groove 711. Using two base rods 51 can increase the rigidity of the structure and provide clearance space through the spacing. Its structural layout is reasonable. The figure 7-shaped pull rod 5 can pull the tilting frame 2 to slide when it rotates. Since the tilting frame 2 slides on the guide shaft 3 through the bushing, further pulling can drive the tilting frame 2 to rotate, realizing a clearance action. The structure is simple and the layout is relatively reasonable. Of course, a cylinder or electric cylinder can also be used to drive the figure 7-shaped pull rod 5 to rotate.

[0025] The bushing 4 is also provided with a suspension roller 30. The suspension roller 30 is rotatably mounted on the bushing 4, and the bushing 4 is hung on the guide shaft 3 via the suspension roller 30. This can reduce the friction when the bushing 4 slides and facilitate the bushing 4 to rise through the inclined guide section 32.
