Description

Technical Field

[0001] The invention relates to the technical field of massage chairs, and in particular to a cylinder thrust driven sliding sleeve type calf side rotation giving way mechanism. Background Art

[0002] The calf units in massage chairs usually include electric rollers or air bags, which can simulate the kneading, tapping and squeezing of the calf by human hands. These units can automatically wrap the user's calf according to the user's calf size to adapt to different leg shapes. The electric roller moves along the contour of the calf to provide acupressure and massage effects, while the air bag simulates squeezing massage by inflating and deflating, promoting blood circulation in the legs and relieving muscle fatigue. Some advanced massage chairs may also include a heat compress function to further enhance the relaxation effect.

[0003] The calf massage mechanism of most massage chairs has the function of lifting and massaging, so that the user can lie down for massage. However, when using it, the calf is embedded in the calf massage mechanism, which makes it difficult to stand up. In particular, this type of massage chair cannot be used by the elderly, pregnant women, children or people with arm injuries.

[0004] In the prior art, there is an invention patent application in China, with the patent number: 202411838501.7, and the patent name is: Calf unit translational seat-taking control method and mechanism, which uses the calf unit translation method to perform an avoidance, so that a standing space is generated in the middle of the calf frame, thereby overcoming the problem of calf embedding, but: because the overall width of the calf frame itself is limited, if the translation method is used, the space in the middle will be limited, it is not easy to stand, and the space is relatively compact when standing, which is easy to trip the elderly or pregnant women. Summary of the invention

[0005] Purpose of the invention: In order to overcome the defects of the prior art, the present invention provides a cylinder thrust-driven sliding sleeve calf side rotation and giving way mechanism, which adopts the cylinder force pushing method to drive the flip frame to slide and rotate, thereby releasing the space on the front side of the calf frame, allowing the elderly and pregnant women to stand more conveniently, and can also prevent tripping, and is more practical.

[0006] The present invention discloses a cylinder thrust driven sliding sleeve type calf side rotation and yielding mechanism, comprising a base, a seat frame and a calf frame, wherein the calf frame is provided with a foot massage mechanism and a calf massage mechanism, and is characterized in that: the calf frame is provided with a turning frame and a rotation and yielding driving component for driving the turning frame to rotate to one side, the foot massage mechanism and the calf massage mechanism are both fixedly arranged on the turning frame, the rotation and yielding driving component comprises a guide shaft horizontally arranged on the calf frame, a shaft sleeve sliding on the guide shaft, a pull rod swingably arranged on the calf frame and a telescopic driving member capable of relatively telescopically driving the pull rod to swing, a first hinge shaft is arranged on one side of the turning frame on the calf frame, one end of the pull rod is hingedly arranged on the first hinge shaft, and the other end is hingedly arranged on the turning frame, a mounting shaft is arranged at the bottom of the shaft sleeve, the turning frame is hung on the mounting shaft and can rotate relative to the mounting shaft.

[0007] A further configuration of the present invention: the pull rod is arranged in a 7-shape as a whole, and is formed by two bottom rods and a driving rod, the two bottom rods are arranged at intervals in the vertical direction to form an avoidance space, a second hinge axis parallel to the first hinge axis is arranged in the avoidance space, the output shaft of the telescopic driving member is hinged on the second hinge axis, the calf frame is also provided with a third hinge axis parallel to the second hinge axis, and the tail of the telescopic driving member is hinged on the third hinge axis.

[0008] The present invention is further configured as follows: the flip frame comprises a main frame, a bracket that can be extended or retracted relative to the main frame, and a bracket driving assembly that drives the bracket to move; the foot massage mechanism and the calf massage mechanism are arranged on the bracket.

[0009] A further configuration of the present invention is that the base is also provided with a seat frame driving component for driving the seat frame to lie down relative to the base and a calf frame driving component for driving the calf frame to lift, and a support wheel is provided at the bottom of the bracket.

[0010] A further configuration of the present invention is that the support wheels are provided with at least two groups, the bracket is further provided with a fourth hinge shaft, the fourth hinge shaft is provided in parallel with the guide shaft, and the support wheels are rotatably sleeved on the fourth hinge shaft.

[0011] The beneficial effects of the present invention are as follows: when in use, it is assembled on the massage chair, and the calf massage mechanism and the foot massage mechanism can massage the user. When the massage is completed, the telescopic driving member is extended to make the pull rod rotate around the first hinge axis. At the same time, because the pull rod is hinged to the flip frame, the flip frame will be pulled when it rotates. Because the flip frame is hung on the mounting shaft, and because of the guiding cooperation between the bushing and the guide shaft, the flip frame can slide and rotate at the same time, thereby releasing the space on the front side of the calf frame, allowing the elderly and pregnant women to stand more conveniently, and also preventing tripping, so it is more practical, and adopts the direct push mode of the telescopic driving member, which can exert better force and is more stable and convenient to control.

Detailed Description of the Preferred Embodiments

[0013] The following further describes the detailed embodiments of the present invention with reference to the accompanying drawings: In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and 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 of the present invention.

[0014] The present invention discloses a cylinder thrust driven sliding sleeve type calf side rotation and giving way mechanism, comprising a base 1, a seat frame 2 and a calf frame 3, wherein the calf frame 3 is provided with a foot massage mechanism 4 and a calf massage mechanism 5, the foot massage mechanism 4 can massage the foot and can also clamp the foot, the specific structure belongs to the prior art, and is not the main invention point of the present invention, and will not be introduced in detail in this article, the calf massage mechanism 5 can be massaged by an air bag or a roller, which belongs to the prior art, and will not be introduced in detail in this article, in the implementation case of the present invention, the calf frame 3 is provided with a flip frame 6 and a rotary mechanism for driving the flip frame 6 to rotate to one side to give way The driving assembly, the foot massage mechanism 4 and the calf massage mechanism 5 are all fixedly arranged on the turning frame 6. The driving assembly includes a guide shaft 71 horizontally arranged on the calf frame 3, a sleeve 72 slidingly guided on the guide shaft 71, a pull rod 73 swingably arranged on the calf frame 3, and a telescopic driving member 74 that can relatively telescope and drive the pull rod 73 to swing. A first hinge shaft 8 is arranged on the calf frame 3 at one side of the turning frame 6. One end of the pull rod 73 is hingedly arranged on the first hinge shaft 8, and the other end is hingedly arranged on the turning frame 6. A mounting shaft 721 is arranged at the bottom of the sleeve 72. The turning frame 6 is hung on the mounting shaft 721 and can rotate relative to the mounting shaft 721.

[0015] The above technical solution is adopted and assembled on the massage chair when in use. The calf massage mechanism 5 and the foot massage mechanism 4 can massage the user. When the massage is completed, the telescopic drive member 74 is extended (the telescopic drive member 74 is most preferably a cylinder, but it can also be a telescopic motor or electric cylinder), so that the pull rod 73 rotates along the first hinge axis 8. At the same time, because the pull rod 73 is hinged to the flip frame 6, the flip frame 6 will be pulled when it rotates. Because the flip frame 6 is hung on the mounting shaft 721, and because of the guiding cooperation between the shaft sleeve 72 and the guide shaft 71, the flip frame 6 can slide and rotate at the same time, thereby releasing the space on the front side of the calf frame 3, allowing the elderly and pregnant women to stand more conveniently, and also preventing tripping, which is more practical. In addition, the telescopic drive member 74 is directly pushed, which has better force and is more stable and convenient to control.

[0016] The pull rod 73 is integrally arranged in a "7" shape and is formed by two bottom rods 731 and a driving rod 732. The two bottom rods 731 are arranged at intervals in the vertical direction to form an avoidance space 9. A second hinge shaft 10 parallel to the first hinge shaft 8 is arranged at the avoidance space 9. The output shaft of the telescopic driving member 74 is hinged to the second hinge shaft 10. A third hinge shaft 20 parallel to the second hinge shaft 10 is also arranged on the calf support 3. The tail of the telescopic driving member 74 is hinged to the third hinge shaft 20. Because of the direct pushing mode of the telescopic driving member 74, the pull rod 73 needs to be provided with an avoidance space 9 for it to rotate and avoid. Using two bottom rods 731 can not only increase the stiffness of the structure but also provide an avoidance space by means of intervals. Its structural layout is reasonable, and the first hinge shaft 8, the second hinge shaft 10, and the third hinge shaft 20 are parallel, which can drive the translation and flipping of the flipping frame 6 more stably.

[0017] The flipping frame 6 includes a main frame 61, a bracket 62 that can extend or retract relative to the main frame 61, and a bracket driving assembly 30 for driving the movement of the bracket 62 (the bracket driving assembly 30 is most preferably a motor and a screw rod. Of course, it can also be driven by an electric cylinder or a cylinder). The foot massage mechanism 4 and the calf massage mechanism 5 are arranged on the bracket 62. With this driving method, the foot massage mechanism 4 can also stretch and contract with the bracket, so as to achieve the effect of tendon pulling.

[0018] The base 1 is also provided with a seat-back frame driving member 40 for driving the seat-back frame 2 to recline relative to the base 1 and a calf support driving member 50 for driving the calf support 3 to lift (the seat-back frame driving member 40 and the calf support driving member 50 are most preferably electric push rods. The specific installation method belongs to conventional technical means and will not be introduced in detail in this article). A support wheel 60 is arranged at the bottom of the bracket 62, so that the seat-back frame 2 can recline relative to it, and the calf support 3 can lift relative to it. And setting the support wheel 60 at the bottom of the bracket 62 can usually play a supporting role for the flipping frame 6. When the flipping frame 6 needs to avoid, the calf support driving member 50 can first drive the calf support 3 to lift, so that the support wheel 60 is separated from the ground, which can play a role in reducing friction and prevent damage to the ground and the support wheel 60.

[0019] At least two groups of the support wheels 60 are provided. A fourth hinge shaft 70 is also arranged on the bracket 62. The fourth hinge shaft 70 is arranged parallel to the guide shaft 71. The support wheel 60 is rotatably sleeved on the fourth hinge shaft 70. Multiple groups of support wheels 60 can play a better supporting role, and the support wheel 60 is rotatably arranged on the fourth hinge shaft 70, which is convenient for its later handling and transportation.
