Description

Technical Field

[0001] The invention relates to the technical field of massage chairs, and in particular to a motor torque driven sliding shaft type calf lateral 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 motor torque driven sliding shaft calf side rotation and giving way mechanism, which uses a rotating and giving way method to release the space on one side, so that the elderly and pregnant women can stand more conveniently, and can also prevent tripping, and is more practical.

[0006] The present invention discloses a motor torque-driven sliding shaft type calf side-rotation yielding mechanism, which includes a base, a seat-back frame that can lie down relative to the base, and a calf frame that can be flipped and lifted relative to the seat-back frame. A foot massage mechanism and a calf massage mechanism are provided on the calf frame. The characteristic lies in that: a flipping frame is provided on the calf frame, and a yielding drive assembly for driving the flipping frame to rotate and yield to one side is provided. The foot massage mechanism and the calf massage mechanism are both fixedly arranged on the flipping frame. The yielding drive assembly includes a guiding groove horizontally arranged on the calf frame, a guiding shaft arranged on the flipping frame and guiding and sliding circumferentially in the guiding groove, a pull rod arranged on the calf frame for pulling the flipping frame to slide and rotate, and a pull rod drive member for driving the pull rod to rotate. When the pull rod drive member drives the pull rod to rotate, the pull rod can drive the flipping frame to slide and rotate along the guiding groove.

[0007] A further setting of the present invention: The pull rod is arranged in a shape of '7'. The pull rod drive member is a driving motor vertically installed on one side of the calf frame. One end of the pull rod is fixed to the output shaft of the driving motor, and the other end is hingedly arranged on the flipping frame.

[0008] A further setting of the present invention: Universal rollers in contact with the ground are provided at the bottom of the flipping frame, and the bottom of the universal rollers exceeds the bottom of the foot massage mechanism.

[0009] A further setting of the present invention: The flipping frame includes a main frame, a bracket that can extend or retract relative to the main frame, and a bracket drive assembly for driving the movement of the bracket. The foot massage mechanism and the calf massage mechanism are arranged on the bracket.

[0010] A further setting of the present invention: Guide rails are arranged on opposite sides of the main frame, and guide rollers are arranged on the bracket corresponding to the positions of the guide rails. The guide rollers are rollingly arranged in the guide rails.

[0011] Adopting the above technical solution, during use, a drive assembly is arranged on the base, which can drive the calf frame to lift or lower, and can also drive the seat-back frame to lie down relatively. After the massage is completed, the calf frame is put down relatively. At this time, the pull rod drive member can drive the pull rod to rotate. Because the flipping frame is guided and slides in the guiding groove through the guiding shaft, it will drive the flipping frame to slide to one side. Because the rotational torque can drive the flipping frame to rotate relatively, the foot massage mechanism and the calf massage mechanism can be driven to one side, which can reserve enough space for the user to stand up. At the same time, adopting this drive method will not affect the expansion and contraction of the foot massage mechanism, enabling the mechanism to achieve more massage functions, with higher practicability. Moreover, when the flipping frame rotates and yields, it vacates the space on one side, and the flipping frame is not located in the middle, which is more convenient for the user to get up compared to reserving a part of the space in the middle.

[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 relationships indicated by the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are 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 thus should not be construed as a limitation to the present invention.

[0014] The present invention discloses a motor torque-driven sliding shaft type calf side-rotation yielding mechanism, which includes a base 1, a seat-back frame 2 that can lie down relative to the base 1, and a calf frame 3 that can be turned up and lifted relative to the seat-back frame 2. A foot massage mechanism 4 and a calf massage mechanism 5 are provided on the calf frame 3. 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 inventive point of the present invention, so it will not be introduced in detail herein. The calf massage mechanism 5 can use an airbag or a roller for massage, which specifically belongs to the prior art and will not be introduced in detail herein. In the embodiment of the present invention, a turning frame 6 is provided on the calf frame 3, and a yielding drive assembly for driving the turning frame 6 to rotate and yield to one side. The foot massage mechanism 4 and the calf massage mechanism 5 are both fixedly arranged on the turning frame 6. The yielding drive assembly includes a guiding groove 71 horizontally arranged on the calf frame 3, a guiding shaft 72 arranged on the turning frame 6 and guiding and sliding circumferentially in the guiding groove 71, a pull rod 73 arranged on the calf frame 3 for pulling the turning frame 6 to slide and rotate, and a pull rod drive member 74 for driving the pull rod 73 to rotate. When the pull rod drive member 74 drives the pull rod 73 to rotate, the pull rod 73 can drive the turning frame 6 to slide and rotate along the guiding groove 71.

[0015] With the above technical solution, during use, a drive assembly is arranged on the base 1 (the most preferred drive assembly is an electric push rod, and the specific installation method belongs to the common knowledge of those skilled in the art), which can drive the calf frame 3 to lift or lower, and can also drive the seat-back frame 2 to lie down relatively. After the massage is completed, the calf frame 3 is put down relatively. At this time, the pull rod drive member 74 can drive the pull rod 73 to rotate. Since the turning frame 6 is guided and slides in the guiding groove 71 through the guiding shaft 72, it will drive the turning frame 6 to slide to one side. Because the rotational torque can drive the turning frame 6 to rotate relatively, the foot massage mechanism 4 and the calf massage mechanism 5 can be driven to one side, leaving enough space for the user to stand up. At the same time, using this drive method will not affect the telescoping of the foot massage mechanism 4, enabling the mechanism to achieve more massage functions and higher practicability. Moreover, when the turning frame 6 rotates and yields, it vacates the space on one side, and the turning frame 6 is not located in the middle. Compared with reserving a part of the space in the middle, it is more convenient for the user to get up. Most preferably, a limit plate can also be provided at the top of the guiding shaft to support on the outer edge of the guiding groove to prevent the turning frame 6 from falling. In addition, an avoidance hole is provided on the calf frame 3. When the top support rod of the turning frame 6 is too protruding, there will be some obstacles during its rotation and yielding, and it can be successfully avoided through the avoidance hole. Of course, it can also be to use a mounting frame to translate the turning frame 6 outward by a certain space to reserve the yielding space, or to shorten the length of the top support rod of the turning frame 6 to avoid touching the calf frame 3 during yielding.

[0016] The pull rod 73 is arranged in a shape of "7". The pull rod driving member 74 is a driving motor vertically installed on one side of the calf support 3. One end of the pull rod 73 is fixed to the output shaft of the driving motor, and the other end is hinged to the flipping frame 6. The "7"-shaped pull rod 73 can pull the flipping frame 6 to slide when rotating. Since the flipping frame 6 is guided and slides in the guide groove 71 through the guide shaft 72, at this time, further pulling can drive the flipping frame 6 to rotate, realizing an avoidance action. The structure is simple and the layout is relatively reasonable. Of course, it can also be a cylinder or an electric cylinder driving the "7"-shaped pull rod 73 to rotate.

[0017] Universal rollers 8 in contact with the ground are provided at the bottom of the flipping frame 6. The bottom of the universal rollers 8 extends beyond the bottom of the foot massage mechanism. The universal rollers 8 can play a supporting role, prevent deformation at the joint of the pull rod 73 and the guide shaft 72, and can reduce the friction during its flipping, reducing energy loss.

[0018] 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 9 for driving the movement of the bracket 62 (the bracket driving assembly 9 is most preferably a motor and a screw rod, which is easy to control and has higher safety during tendon pulling). 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 extend and retract with the bracket 62, thus achieving the effect of tendon pulling.

[0019] Guide rails 10 are provided on opposite sides of the main frame 61. Guide rollers 20 are provided on the bracket 62 corresponding to the positions of the guide rails 10. The guide rollers 20 are rollingly arranged in the guide rails 10, which can reduce the friction when the bracket 62 slides and can play a role in guiding and sliding.
