[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Specific embodiments

[0044] The present invention will be further described below through specific embodiments.

[0045] In the present invention, for terms such as "first", "second", "third", etc., they are only used to distinguish similar objects and do not have to be used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. In the description, the orientation or positional relationship indicated by "upper", "lower", "left", "right", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and does not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present invention. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] In addition, in the description of this application, unless otherwise specified, "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0047] See Figures 1 to 11, A foot massage device, including a first frame body 10, a power component 20, a foot massager 30, a swing component 40, etc. A bottom plate 11 is provided on the first frame body 10 to support components such as the power component 20 and the foot massager 30. The power component 20 is installed on the bottom plate 11 of the first frame body 10. The power component 20 is used to drive the swing component 40 to move, and it is provided with a rotatable driving part 21 for outputting circumferential rotation. The foot massager 30 is located above the first frame body 10 and is provided with a receiving groove 31 to accommodate the foot. A massage component, such as a massage roller, etc., is also provided inside the bottom wall of the receiving groove 31 to perform a massage action. Of course, since the purpose of the design of the foot massager 30 is to drive the user's foot to swing in the front-back direction and the left-right direction, and this kind of swing itself is a kind of massage, so, other massage mechanisms may not be provided on this foot massager 30. The swing component 40 is connected between the power component 20 and the foot massager 30 for transmission and driving the foot massager 30 to swing.

[0048] In this embodiment, the swing component 40 includes a swing frame 41, a bracket 44 and a transmission mechanism 50. The swing frame 41 is a frame structure that is vertically penetrated, and its main body can be square, circular or other polygons, etc. The bracket 44 is fixed on the bottom plate 11. The middle part of the swing frame 41 is hinged to the bracket 44, so that the left and right sides of the swing frame 41 can swing up and down. The swing frame 41 is provided with a connecting shaft 43. The foot massager 30 is hinged to the connecting shaft 43, so that the foot massager 30 can rotate relative to the swing frame 41, and further the foot massager 30 can swing up and down in the front-back direction. Also, because the left and right sides of the swing frame 41 can swing up and down, so, the swing frame 41 can drive the foot massager 30 to also swing up and down in the left-right direction. Among them, the left-right direction means that when the user's foot is placed in the receiving groove 31, the side where the user's left hand is located is the left side, the side where the user's right hand is located is the right side, and the side where the user's front is located is the front side.

[0049] Specifically, in order to better install the swing frame 41, the swing component 40 is provided with two connecting plates 45. The two connecting plates 45 extend in the height direction and are arranged parallel and spaced on the front and rear sides of the bracket 44. The swing frame 41 is located between the two connecting plates 45. The front side and the rear side of the swing frame 41 are respectively rotatably connected to the two connecting plates 45 of the bracket 44, so that the left and right sides of the swing frame 41 can swing up and down. The connecting shaft 43 penetrates between the left side and the right side of the swing frame 41, and bearings are also sleeved at the ends of the connecting shaft 43 for rotatable connection with the swing frame 41. The connecting shaft 43 also penetrates through the left and right sides of the foot massager 30.

[0050] In order to drive the foot massager 30 to swing back and forth and left and right, a connecting seat 32 is provided on one side of the foot massager 30 close to the swing assembly 40. The connecting seat 32 protrudes outward from the bottom surface of the foot massager 30 for the connecting shaft 43 to pass through. The swing frame 41 is arranged outside the connecting seat 32, and there is a gap between the two.

[0051] The input end of the transmission mechanism 50 is in transmission cooperation with the driving part 21, and the driving part 21 drives the transmission mechanism 50 to act through its circumferential movement.

[0052] Please refer to Figure 6 , the transmission mechanism 50 includes a first rotating shaft 51, a first transmission wheel 52 and a rotating plate 53. The first rotating shaft 51 extends in the height direction and is rotatable relative to the first frame body 10. Specifically, the bottom end of the first rotating shaft 51 is hinged to the bracket 44. The first transmission wheel 52 is fixedly connected to the first rotating shaft 51 and is driven to rotate by the driving part 21, so that the first transmission wheel 52 can drive the first rotating shaft 51 to rotate. The rotating plate 53 is vertically connected to the top end of the first rotating shaft 51 close to the swing frame 41. A sleeve 54 is fixed on the top end of the first rotating shaft 51. The sleeve 54 is used to support the rotating plate 53. The sleeve 54 plays a role in connecting the first rotating shaft 51 and the rotating plate 53. The sleeve 54 and the rotating plate 53 adopt a split structure for easy manufacturing. When the first rotating shaft 51 rotates, when the first rotating shaft 51 drives the rotating plate 53 to rotate, the rotating plate 53 is provided with transmission surfaces 53a with different heights.

[0053] Please refer to Figure 5 and Figure 11 , the transmission surface 53a includes a first surface 53b with a lower height in the up-and-down direction and a second surface 53c with a higher height. The first surface 53b and the second surface 53c are respectively located on both sides in the radial direction of the first rotating shaft 51. The bottom end of the connecting seat 32 is also an undulating structure 33 with different heights. The transmission surface 53a of the rotating plate 53 faces the undulating structure 33 at the bottom end of the connecting seat 32. Specifically, the front side of the bottom end of the connecting seat 32 is higher, and the rear side is lower than the front side; the left side and the right side are lower than the front side, and the left side and the right side are higher than the rear side, and the left side and the right side have the same height. In the figure, the undulating structure 33 is similar to an inclined plane. The undulating structure 33 is not limited to this, and the height of different sides of the bottom end of the connecting seat 32 can also be adjusted according to the actual situation.

[0054] During operation, when the front side of the bottom end of the connecting seat 32 abuts against the second surface 53c, the front side of the foot massager 30 tilts upward. When the rear side of the bottom end of the connecting seat 32 abuts against the second surface 53c, the rear side of the foot massager 30 tilts upward; when the left side of the bottom end of the connecting seat 32 abuts against the second surface 53c, the left side of the foot massager 30 tilts upward, and when the right side of the bottom end of the connecting seat 32 abuts against the second surface 53c, the right side of the foot massager 30 tilts upward. The same applies to other situations. When the rotating plate 53 rotates, since the first surface 53b and the second surface 53c also rotate, it drives the left and right sides of the foot massager 30 to swing reciprocally up and down and the front and rear sides to swing reciprocally up and down.

[0055] The power assembly 20 includes a housing 22, a drive motor 23, and a gear set 24. The housing 22 is fixed to the first frame 10 and can be divided into an upper housing 22a and a lower housing 22b. The upper housing 22a and the lower housing 22b are fixedly assembled to form an accommodation space. The drive motor 23 is installed in the accommodation space inside the housing 22 and is provided with a drive shaft 26. The drive shaft 26 is a worm. The input gear 25 of the gear set 24 is in transmission cooperation with the drive shaft 26, that is, the input gear 25 meshes with the worm. A small gear 27 is also connected to the rotating shaft of the input gear 25. The output gear of the gear set 24 meshes with the small gear 27 and serves as the drive part 21. The output gear meshes and drives with the first transmission wheel 52 of the transmission mechanism 50.

[0056] The foot massage device of this embodiment includes two foot massagers 30 which are distributed left and right on the first frame 10. Correspondingly, it includes two swing assemblies 40 which are respectively connected to the two foot massagers 30 one by one; the power assembly 20 is provided with two drive shafts 26 and two gear sets 24. The drive shaft 26 drives the corresponding gear set 24 to act so that the drive part 21 drives the corresponding foot massager 30 to swing reciprocally up and down. The specific working principle is as follows:

[0057] When the power assembly 20 operates, the drive motor 23 drives the gear set 24 to rotate. The two drive parts 21 respectively drive the first transmission wheels 52 of the two swing assemblies 40 to rotate. The first transmission wheel 52 drives the rotating plate 53 to rotate. During the rotation of the rotating plate 53, since the first surface 53b and the second surface 53c also rotate circumferentially, the position on the connecting seat 32 that contacts the first surface 53b drives the foot massager 30 to swing downward, and the position on the connecting seat 32 that contacts the second surface 53c drives the foot massager 30 to swing upward. With the rotation of the first surface 53b and the second surface 53c, the effect of the left and right sides of the foot massager 30 swinging reciprocally up and down and the front and rear sides swinging reciprocally up and down is achieved, so that the user's ankles can be fully stretched and stretched, thereby quickly relieving the soreness and fatigue of the feet.

[0058] Based on this, see Figures 12 - 18, this embodiment also provides a massage chair, which includes a seat body 60 and a leg massage device 70. The seat body 60 is the main structure of the massage chair, and it may include a seat frame 61, a backrest frame 62, etc. Necessary components such as massage components are respectively arranged on the seat frame 61 and the backrest frame 62. The leg massage device 70 is rotatably connected to the seat body 60, that is, the leg massage device 70 can rotate upward or downward relative to the seat body 60.

[0059] The leg massage device 70 includes a calf massage component and the above-mentioned foot massage device. Among them, the calf massage device includes a second frame body 71 and a calf massager 72. A round shaft 63 is arranged at the front end of the backrest frame 62 of the seat body 60, and the second frame body 71 is rotatably connected to the round shaft 63. The calf massager 72 is installed on the second frame body 71. The calf massager 72 is provided with an empty slot 73 for placing the calf, and the empty slot 73 communicates with the accommodation slot 31 of the foot massager 30. The number of calf massagers 72 corresponds to the number and position of the foot massagers 30.

[0060] The first frame body 10 of the foot massage device is slidably connected to the second frame body 71, that is, the distance between the foot massager 30 and the calf massager 72 can be adjusted to realize the adjustment of the overall size of the leg massager to meet the needs of different users. Specifically, guide rails 12 are respectively arranged on the left and right sides of the first frame body 10, and the guide rails 12 extend in the height direction. A screw rod 14 is arranged at the rear side of the first frame body 10. A plurality of rollers 75 are respectively arranged on the left and right sides of the second frame body 71 at intervals in the height direction, and a nut 74 is arranged at the rear side of the second frame body 71. The nut 74 is in threaded cooperation with the screw rod 14. The guide rails 12 on the first frame body 10 are slidably matched with the corresponding rollers 75 on the second frame body 71. By driving the screw rod 14 to rotate, the first frame body 10 is driven to slide relative to the second frame body 71 to realize the adjustment of the distance between the foot massager 30 and the calf massager 72.

[0061] The above is only the specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto.
