Abstract
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 planar rotation function. 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 existing technologies, foot massage mechanisms are moved directly to the sides to expose the middle part, making it easier for people to stand. However, the middle part is limited after the mechanism is moved, which still has 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 planar rotation function. By using a side sliding and rotating method, the space on one side of the lower leg support can be released, which solves the problem of narrow space and makes it more convenient for users to stand.
[0006] This utility model discloses a relative motion support steel structure with planar rotation function, including a lower leg frame. The lower leg frame is characterized by having a flipping frame and a rotation drive assembly for driving the flipping frame to rotate to one side. The rotation drive assembly includes a guide member that slides laterally on the lower leg frame, a tie rod that swings on the lower leg frame, and a tie rod drive member that drives the tie rod to swing. One end of the tie rod is linked to the tie rod drive member, and the other end is hinged to the flipping frame. The flipping frame is connected to the guide member and can rotate relative to the lower leg frame.
[0007] A further feature of this invention is that the pull rod is arranged in a figure-7 shape, and the pull rod drive component is a drive motor that is vertically mounted on one side of the lower leg frame. One end of the pull rod is fixed to the output shaft of the drive motor, and the other end is hinged to the tilting frame.
[0008] A further feature of this invention is as follows: a first hinge shaft is provided on one side of the lower leg frame, and one end of the pull rod that cooperates with the lower leg frame is hinged to the first hinge shaft. The pull rod is generally arranged in a figure-7 shape 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. A second hinge shaft parallel to the first hinge shaft is provided in the clearance space. The pull rod drive component is a cylinder, and the output shaft of the cylinder is hinged to the second hinge shaft. The lower leg frame is also provided with a third hinge shaft parallel to the second hinge shaft, and the tail of the pull rod drive component is hinged to the third hinge shaft.
[0009] Further features of this invention: the guide component is a guide sleeve, a guide rod is horizontally provided on the lower leg frame, the guide sleeve slides on the guide rod, an installation shaft is provided at the bottom of the guide component, the flipping frame is hung on the installation shaft and can rotate relative to the installation shaft. Of course, the guide component can also be a guide shaft, a long slot is horizontally provided on the lower leg frame, the guide shaft slides in the long slot and is suspended on the lower leg frame.
[0010] A further feature of this invention is that the tilting frame includes a main frame, a support that can extend or retract relative to the main frame, and a support drive assembly that drives the support to move.
[0011] The specific beneficial effects of this utility model are as follows: When in use, it is assembled onto a massage chair, and the calf massage mechanism and foot massage mechanism can provide massage to the user. After the massage is completed, the pull rod drive component works, causing the pull rod to rotate along the first hinge axis. At the same time, because the pull rod is hinged to the flip frame, the rotation will pull the flip frame. Since the flip frame is hung on the mounting shaft and guided by the guide component to slide on the calf frame, the flip frame can simultaneously perform two actions of sliding and rotating, thereby releasing the space on the front side of the calf frame, making it easier for the elderly and pregnant women to stand, and also preventing tripping, thus enhancing its practicality.

[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 relative motion support steel structure with planar rotation function, including a lower leg frame 1. In an embodiment of this utility model, the lower leg frame 1 is provided with a flipping frame 2 and a rotation drive assembly for driving the flipping frame 2 to rotate to one side. The rotation drive assembly includes a guide member that slides laterally on the lower leg frame 1, a tie rod 3 that swings on the lower leg frame 1, and a tie rod drive member that drives the tie rod 3 to swing. One end of the tie rod is linked with the tie rod drive member, and the other end is hinged to the flipping frame 2. The flipping frame 2 is connected to the guide member and slides synchronously with it, and the flipping frame 2 can rotate relative to the lower leg frame 1.
[0023] Using the above technical solution, when in use, it is assembled onto a massage chair. The calf massage mechanism and foot massage mechanism can provide massage to the user. After the massage is completed, the pull rod drive works, causing the pull rod 3 to rotate relative to the user. At the same time, because the pull rod 3 is hinged to the flip frame 2, the rotation will pull the flip frame 2. Since the flip frame 2 is connected to the guide, the guide slides on the calf frame 1. And because the flip frame 2 can rotate relative to the calf frame 1, the flip frame 2 can simultaneously perform two actions: sliding and rotating. This releases the space in front of the calf frame 1, making it easier for the elderly and pregnant women to stand up, and also preventing them from tripping. This makes it more practical.
[0024] The pull rod 3 is arranged in a figure-7 shape. The pull rod drive component is a drive motor 4 that is vertically mounted on one side of the lower leg frame 1. One end of the pull rod 3 is fixed to the output shaft of the drive motor 4, and the other end is hinged to the tilting frame 2. The figure-7 shaped pull rod 3 can pull the tilting frame 2 to slide when it rotates. Since the tilting frame 2 is guided to slide on the lower leg frame 1 by the guide component, further pulling can drive the tilting frame 2 to rotate, thus achieving an avoidance action. The structure is simple and the layout is relatively reasonable.
[0025] A first hinge shaft 5 is provided on one side of the lower leg frame 1. The end of the pull rod that cooperates with the lower leg frame 1 is hinged to the first hinge shaft 5. The pull rod 3 is generally arranged in a "7" shape and is formed by two base rods 6 and one drive rod 7. The two base rods 6 are arranged at intervals in the vertical direction to form a clearance space. A second hinge shaft 8 parallel to the first hinge shaft 5 is provided in the clearance space. The pull rod drive component is a cylinder 9. The output shaft of the cylinder 9 is hinged to the second hinge shaft 8. The lower leg frame 1 is also provided with a third hinge shaft parallel to the second hinge shaft 8. The tail of the pull rod drive component is hinged to the third hinge shaft. Because of the direct push method of the cylinder, the pull rod 3 needs to be provided with clearance space for its rotation clearance. Using two base rods 6 can not only increase the rigidity of the structure, but also provide clearance space by interval. Its structural layout is reasonable. Furthermore, the first hinge shaft 4, the second hinge shaft 8 and the third hinge shaft are parallel, which can drive the tilting frame 2 to translate and tilt more stably.
[0026] The guide component is a guide sleeve 10. A guide rod 20 is horizontally provided on the lower leg frame 1. The guide sleeve 10 slides on the guide rod 20. An installation shaft 101 is provided at the bottom of the guide component. The flipping frame 2 is hung on the installation shaft 101 and can rotate relative to the installation shaft 101. Of course, the guide component can also be a guide shaft 30. A long slot 40 is horizontally provided on the lower leg frame 1. The guide shaft 30 slides in the long slot 40 and is suspended on the lower leg frame 1. The side sliding of the flipping frame 2 can be achieved through the cooperation of the guide sleeve 10 and the guide rod 20. At the same time, the flipping frame 2 can rotate relative to the installation shaft 101, thus achieving flipping. The same applies to the guide shaft 30 and the long slot 40.
[0027] The flip frame 2 includes a main frame 21, a support 22 that can extend or retract relative to the main frame 21, and a support drive assembly 50 that drives the support 22 to move. The position of the support 22 can be adjusted, thereby adjusting the overall length of the flip frame 2. When it is assembled onto a massage chair and the foot massage mechanism is placed on the support 22, it can also achieve the effect of tendon pulling. The support drive assembly 50 is preferably composed of a motor and a screw. The specific installation method is a conventional technical means, and will not be described in detail in this article.
