Description

Technical Field

[0001] The invention relates to the technical field of massage chairs, and in particular to a gear shaft-driven roller-type calf side-rotation-displacing mechanism with a lifting function. 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 a calf side rotation mechanism, which uses a flip frame to install a foot massage mechanism and a calf massage mechanism, and drives the foot massage mechanism and the calf massage mechanism to avoid by sliding and flipping. The calf massage mechanism and the foot massage mechanism are relatively heavy, and long-term suspension may easily cause deformation of the load-bearing position of the flip frame, so it is necessary to set a supporting roller at the bottom of the flip frame to prevent the load-bearing position of the flip frame from deforming and increase the service life. However, it uses supporting rollers for support, which will cause obstacles when rotating. Summary of the invention

[0005] Purpose of the invention: In order to overcome the defects of the prior art, the present invention provides a gear shaft driven roller calf side rotation and giving way mechanism with a lifting function, which releases the space on one side by rotating and giving way. The released space is relatively large, so that the elderly and pregnant women can stand more conveniently, and can also prevent tripping, which is more practical. A driving member can drive the flip frame to lift and slide and rotate to one side at the same time, which has the effect of killing two birds with one stone, simplifies the corresponding structure, and reduces the driving cost.

[0006] The present invention discloses a gear shaft rotation drive roller type calf side rotation yielding mechanism with a lifting function, which includes a base, a seat back frame and a calf frame. A foot massage mechanism and a calf massage mechanism are arranged on the calf frame. It is characterized in that: a flipping frame is arranged 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. A support wheel is arranged at the bottom of the flipping frame. The yielding drive assembly includes a guide shaft horizontally arranged on the calf frame, a sleeve slidably guided on the guide shaft, a pull rod swingably arranged on the calf frame, a gear disk for driving the pull rod to rotate, a rack for driving the gear disk to rotate and rise, and a telescopic drive member for driving the rack to extend and retract. The gear disk is suspended on the rack and meshes with it. A hinge shaft is arranged on one side of the calf frame, and the gear disk is rotatably sleeved on the hinge shaft and can axially slide relative to the hinge shaft. One end of the pull rod is arranged on the gear disk and rotates synchronously with it, and the other end is hingedly arranged on the flipping 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 through the inclined connecting section. The guide shaft includes a first guiding section, an inclined guiding section and a second guiding section. The sleeve can rise to the second guiding section or fall to the first guiding section through the inclined guiding section. An installation shaft is arranged at the bottom of the sleeve, and the flipping frame is hung on the installation shaft and can rotate relative to the installation shaft.

[0007] A further setting of the present invention: The gear disk includes a limiting plate and a tooth disk. Two limiting plates are arranged at intervals in the vertical direction. The rack is inserted between the two limiting plates and meshes with the tooth disk, and the top limiting plate abuts against the top of the rack.

[0008] 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.

[0009] A further setting of the present invention: The pull rod is integrally arranged in a shape of '7', 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. Part of the two limiting plates is located in the avoidance space, and an assembly groove is arranged at the position corresponding to the bottom rod on each limiting plate. An opening is arranged on one side of the assembly groove, and part of the bottom rod is located in the assembly groove and extends out of the assembly groove from one side opening.

[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 at positions corresponding to the guide rails. The guide rollers are rotatably arranged in the guide rails.

[0011] A further setting of the present invention: At least two groups of support wheels are provided and are rotatably arranged on the bracket.

[0012] Further setting of the present invention: A suspension roller is further provided on the bushing. The suspension roller is rotatably arranged on the bushing, and the bushing is hung on the guide shaft through the suspension roller.

[0013] The beneficial effects of the present invention are as follows: During use, it is assembled onto the massage chair. The calf massage mechanism and the foot massage mechanism can massage the user. After the massage is completed, the telescopic driving member extends, thereby driving the rack to extend. Since the rack meshes with the gear disk, the gear disk can be driven to rotate, thereby driving the relative rotation of the pull rod. Since the flipping frame is hung on the mounting shaft, and due to the guiding cooperation between the bushing and the guide shaft, the flipping frame can perform two actions simultaneously, namely sliding and rotational turning. When the inclined connecting section of the rack meshes with the gear disk, the bushing is located at the inclined guiding section, and both of them rise simultaneously, so that the flipping frame can be lifted normally without being hindered. Thus, the movement in three directions, namely translation, flipping, and lifting, can be achieved, releasing a relatively large part of the space in front of the calf rack. The released space is relatively large, enabling the elderly and pregnant women to stand more conveniently and preventing tripping. The practicality is stronger. Moreover, one driving member can drive the flipping frame to lift and simultaneously slide and turn to one side, achieving multiple effects with one action, simplifying the corresponding structure and reducing the driving cost.

Detailed Description of the Invention

[0015] The following further details the specific implementation manners of the present invention in conjunction with the 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. It 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 to the present invention.

[0016] The present invention discloses a gear shaft rotary drive roller type calf side rotation yielding mechanism with a lifting function, which includes a base 1, a seat-back frame 2 and a calf frame 3. A foot massage mechanism 4 and a calf massage mechanism 5 are arranged on the calf frame 3. In the embodiment of the present invention, a flipping frame 6 and a yielding drive assembly for driving the flipping frame 6 to rotate and yield to one side are provided on the calf frame 3. The foot massage mechanism 4 and the calf massage mechanism 5 are both fixedly arranged on the flipping frame 6. 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 55 can use air bags or rollers for massage, which specifically belongs to the prior art and will not be introduced in detail herein. A support wheel 8 is arranged at the bottom of the flipping frame 6. The yielding drive assembly includes a guiding shaft 71 horizontally arranged on the calf frame 3, a shaft sleeve 72 slidably guided on the guiding shaft 71, a pull rod 73 swingably arranged on the calf frame 3, a gear disk 74 for driving the pull rod 73 to rotate, a rack 75 for driving the gear disk 74 to rotate and rise, and a telescopic drive member 76 for driving the rack 75 to expand and contract (the telescopic drive member 76 is most preferably a cylinder, and of course, it can also be an electric cylinder or a telescopic motor). The gear disk 74 is suspended on the rack 75 and meshes with it. A hinge shaft 9 is arranged on one side of the calf frame 3, and the gear disk 74 is rotatably sleeved on the hinge shaft 9 and can axially slide relative to the hinge shaft 9. One end of the pull rod 73 is arranged on the gear disk 74 and rotates synchronously with it, and the other end is hinged to the flipping frame 6. The rack 75 includes a first straight section 751, an inclined connecting section 752 and a second straight section 753. The gear disk 74 can rise to the second straight section 753 or descend to the first straight section 751 through the inclined connecting section 752. The guiding shaft 71 includes a first guiding section 711, an inclined guiding section 712 and a second guiding section 713. The shaft sleeve 72 can rise to the second guiding section 713 or descend to the first guiding section 711 through the inclined guiding section 712. An installation shaft 10 is arranged at the bottom of the shaft sleeve 72, and the flipping frame 6 is hung on the installation shaft 10 and can rotate relative to the installation shaft 10.

[0017] With the above technical solution, during use, it is assembled onto a massage chair. The calf massage mechanism 5 and the foot massage mechanism 4 can massage the user. After the massage is completed, the telescopic driving member 76 extends, thereby driving the rack 75 to extend. Since the rack 75 meshes with the gear disk 74, the gear disk 74 can be driven to rotate, thereby driving the pull rod 73 to rotate relatively. Since the flip frame 6 is hung on the mounting shaft 10, and due to the guiding cooperation between the bushing 72 and the guiding shaft 71, the flip frame 6 can perform two actions of sliding and rotational rotation simultaneously. When the inclined connecting section 752 of the rack 75 meshes with the gear disk 74, the bushing 72 is located at the inclined guiding section 712 position, and both of them rise along the inclined slope simultaneously, so that the flip frame 6 can be lifted normally without being hindered, and the movement in three directions of translation, flipping, and lifting can be achieved, releasing a relatively large part of the space in front of the calf rest 3. The released space is relatively large, enabling the elderly and pregnant women to stand more conveniently and preventing tripping, with stronger practicability. Moreover, using one driving member can drive the flip frame 6 to lift and simultaneously slide and rotate to one side, achieving multiple benefits, simplifying the corresponding structure, and reducing the driving cost.

[0018] The gear disk 74 includes a limiting plate 741 and a tooth disk 742. Two limiting plates 741 are arranged at intervals in the vertical direction. The rack 75 is inserted between the two limiting plates 741 and meshes with the tooth disk 742, and the upper limiting plate 741 abuts against the top of the rack 75. The two limiting plates 741 can play a role in preventing the rack 75 from coming off, and facilitate the overall lifting of the gear disk 74 by the rack 75, making the cooperation between the rack 75 and the tooth disk 742 more stable.

[0019] The flip 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 20 for driving the movement of the bracket 62 (the bracket driving assembly 20 is most preferably a motor and a screw rod, which is easy to control during tendon pulling and has higher safety). 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, thereby achieving the effect of tendon pulling.

[0020] The pull rod 73 is integrally arranged in a shape of "7", and is formed by two bottom rods 731 and one driving rod 732. The two bottom rods 731 are arranged at intervals in the vertical direction to form an avoidance space. Part of the two limit plates 741 is located in the avoidance space, and an assembly groove 30 is provided at the position corresponding to the bottom rod 731 on each limit plate 741. An opening 40 is provided on one side of the assembly groove 30. The bottom rod is partially located in the assembly groove 30 and extends from the opening 40 on one side to the outside of the assembly groove 30. 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. Using the "7"-shaped pull rod 73 can drag the turning frame 6 to slide when it rotates. Since the turning frame 6 slides along the guide shaft 71 through the bushing for guiding, at this time, further dragging can drive the turning frame 6 to rotate, realizing an avoidance action. The structure is simple and the layout is relatively reasonable. Of course, it can also be that a cylinder or an electric cylinder is used to drive the "7"-shaped pull rod 73 to rotate.

[0021] Guide rails are provided on opposite sides of the main frame 61, and guide rollers are provided on the bracket 62 at positions corresponding to the guide rails. The guide rollers are rotatably arranged in the guide rails, which can reduce the friction when the bracket 62 slides and can play a role in guiding and sliding.

[0022] At least two groups of support wheels 8 are provided and are rotatably arranged on the bracket 62. The rotation of the support wheels 8 can reduce the friction during handling, thereby improving the convenience of handling.

[0023] A suspension roller 721 is further provided on the bushing 72. The suspension roller 721 is rotatably arranged on the bushing 72, and the bushing 72 is hung on the guide shaft 71 through the suspension roller 721, which can reduce the friction when the bushing 72 slides and is convenient for the bushing 72 to rise along the inclined guiding section 712.
