[0002] The existing calf massage products only have conventional massage functions such as foot bottom rubbing, leg muscle massage, etc., which cannot meet the experience of consumers and attract the attention of consumers. The ankle joint rotation massage of the ankle can improve local blood circulation, relieve fatigue, improve joint flexibility, and assist in relieving sports injuries and chronic pain. Therefore, adding ankle massage function to the existing product function can make the product more competitive. However, adding ankle massage function to the push massage mechanism is limited by space and cannot realize rotation ankle massage. SUMMARY

[0023] In order to make the technical solutions and characteristics of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and specific examples, and it should be understood that these examples are only used to illustrate the present application and not used to limit the scope of the present application, and after reading the present application, those skilled in the art can make various equivalent modifications of the present application, which all fall within the scope defined by the claims of the present application.

[0024] REFERENCE Figures 1-6 The present embodiment provides a foot swinging mechanism for swinging the user's foot along a predetermined trajectory, which comprises: a foot swinging mechanism 1, a walking support 2, the foot swinging mechanism 1 is installed on the walking support 2, and the walking support 2 is arranged on a massage chair frame (not shown in the figure) in an up-and-down sliding manner, so that the walking support 2 can drive the foot swinging mechanism 1 to slide up and down on the massage chair frame.

[0025] The foot swinging mechanism 1 in the present embodiment further comprises: a driving member 11, a transmission member 12, a swinging shaft 13, an eccentric swinging arm 14, a swinging support 15 for supporting the user's foot, a universal ball head 16, a universal shaft 17, and a fixed support 18; the swinging support 15 comprises a first end 155, a second end 156, and a clearance opening 151 arranged between the first end 155 and the second end 156. In order to further increase the function of the leg massage mechanism, a foot bottom massage member 3 is arranged on the swinging support 15, the foot bottom massage member 3 is fixed on the second end 156 and is swung by the second end 156, and massages the foot bottom during the swinging process. The foot bottom massage member 3 comprises a driving motor and two rotating massage heads 32 driven by the driving motor.

[0026] The driving member 11 drives the swing shaft 13 to rotate around its own axis through the transmission member 12. The eccentric swing arm 14 is eccentrically connected to the swing shaft 13. The eccentric swing arm 14 is further provided with a ball socket 144 connected to a universal ball head 16. The universal ball head 16 is fixedly provided with a connecting rod 161 on the side away from the eccentric swing arm 14. The end of the connecting rod 161 is fixedly connected to the first end 155 of the swing bracket 15. It can be understood that the eccentric swing arm 14 does not necessarily need to drive the first end 155 to swing through the universal ball head 16. It can drive the first end 155 and the second end 156 to swing through other structures, such as an inclined hole matched with the connecting rod 161 of the first end 155.

[0027] The universal shaft 17 includes a horizontal shaft 171 and a vertical shaft 172. The fixed bracket 18 is fixed on the walking bracket 2. The vertical shaft 172 is hingedly connected to the fixed bracket 18 in the vertical direction. The fixed bracket 18 includes a connecting plate 181 provided on both sides of the universal shaft 17 along the vertical direction. The connecting plate 181 is provided with a mounting hole. The vertical shaft 172 of the universal shaft 17 is hingedly connected to the mounting hole.

[0028] It further includes a horizontal shaft sleeve 152 matched with the horizontal shaft 171 of the universal shaft 17, a horizontal mounting seat 153, and a groove 154 provided on both sides of the accommodation opening 151. The accommodation opening 151 of the swing bracket 15 is hingedly connected to the horizontal shaft 171 through the groove 154, the horizontal shaft sleeve 152, and the horizontal mounting seat 153, so that the middle part of the swing bracket is hingedly connected to the horizontal shaft 171.

[0029] When the swing shaft 13 rotates, the swing bracket 15 is driven by the eccentric swing arm 14 and the universal ball head 16 to swing around the universal shaft 17 as a fulcrum.

[0030] In operation, the transmission member 12 drives the swing shaft 13 to rotate, which in turn drives the eccentric swing arm 14 to rotate through the swing shaft 13, so that the universal ball head 16 moves in a circular motion with the eccentric swing arm 14. Since the vertical shaft 172 of the universal shaft 17 is hingedly connected to the fixed bracket 18, and the horizontal shaft 171 is hingedly connected to the middle part of the swing bracket, the universal ball head 16 drives the first end 155 of the swing bracket 15 to swing in a horn shape around the universal shaft 17 as a fulcrum through the connecting rod 161. Based on the lever effect, the second end 156 of the swing bracket 15 also swings in a horn shape around the universal shaft 17 as a fulcrum. In this way, the rotation massage of the ankle position is realized, and the foot swing mechanism 1 performs ankle rotation massage within a reasonable range. When the foot swing mechanism 1 is installed on the leg massage mechanism, ankle massage can be performed during the movement of the lower leg bracket, and the left and right leg foot swing mechanisms 1 can be normally used without interference.

[0031] To realize the eccentric swing arm 14 can be connected to the swing shaft 13 and the universal ball head 16, the eccentric swing arm 14 includes eccentric swing arm body 141 and universal ball head cover plate 142; the eccentric swing arm body 141 is provided with the first shaft hole 143 matched with the eccentric swing shaft 13; the universal ball head cover plate 142 is arranged above the eccentric swing arm body 141, and the universal ball head cover plate 142 and the eccentric swing arm body 141 are spliced into the ball socket 144. Because the eccentric swing arm 14 and the swing shaft 13 are eccentrically matched, the ball head connected to the eccentric swing arm 14 will make a circular motion with the eccentric swing arm 14.

[0032] To realize the transmission of the driving member 11 to the swing shaft 13, the transmission member 12 includes a first pulley 121, a second pulley 122, a worm gear 123 and a worm 124; and the driving member 11 is a motor; the first pulley 121 and the second pulley 122 are fixedly connected with the output shaft of the motor and the worm 124 respectively, and the first pulley 121 and the second pulley 122 are connected by a belt transmission; the rotational speed of the worm 124 can be adjusted by adjusting the speed reduction ratio of the first pulley 121 and the second pulley 122. The worm gear 123 and the worm 124 are reversely matched to convert the rotation of the worm 124 around its own axis into the rotation of the worm gear 123 around its own axis; the second shaft hole 125 for mounting the swing shaft 13 is arranged at the axis of the worm gear 123. In this way, the worm gear 123 rotates with the swing shaft 13 coaxial therewith.

[0033] Finally, when the leg massage mechanism performs leg massage, the upper calf and the lower calf will move relatively in the height direction, which will cause the distance between the lower calves on the left and right sides to change, and further cause the foot swing mechanism 1 on the left and right sides to interfere when performing horn-shaped rotary motion. Although the structure of the foot swing mechanism 1 is optimized in the embodiment to ensure that the foot swing mechanism 1 performs ankle joint rotation massage within a reasonable range, interference cannot be completely avoided. Therefore, in the embodiment, the swing shaft 13 is provided with a code disc 19, and the code disc 19 cooperates with a counting clamp 191 to control the movement position of the lower calf by software, thereby avoiding collision and interference of the foot swing mechanism 1 of the left and right calves when moving.

[0034] The above is only one specific embodiment of the present application, but the design concept of the present application is not limited thereto, and any non-essential modification of the present application using this concept shall be deemed as an infringement of the protection scope of the present application.
