[0002] Lower limb massagers are a common feature in massage chairs, primarily designed to massage the user's feet, though some models massage both the feet and legs. For example, Chinese patent document CN222195483U describes a lower limb massager, see attached document. Figure 5 The instruction manual

[16] states that "the swing plate 22 swings up and down around the pivot 3 with the pivot 3 as the center of rotation." Its function is to move the user's feet on the swing plate, stretch the calf muscles, and provide foot massage. The swing plate in the above solution swings the user's feet synchronously, which cannot imitate the alternating swinging motion of the human body when walking. Traditional lower limb massagers cannot meet the user's need for massage that simulates alternating steps, resulting in a poor massage experience. Utility Model Content

[0003] The purpose of this invention is to provide a lower limb massager that uses independently controlled footrests to meet the user's needs for synchronous and staggered foot swings, thereby enhancing the massage experience.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example 1, a lower limb massager, referring to Figure 1 and Figure 2 It includes a leg 21, which includes a crossbar 211, and a first vertical bar is welded and fixed on both sides of the crossbar 211.

[0019] A support seat 212 extending outward is fixed to the side of the crossbar 211. The support seat 212 is a triangular metal frame and is welded to the crossbar 211. There are four support bases 212, and two support bases 212 form a group; The main body of the footboard 22 is a rectangular frame structure. The footboard 22 is located between a set of support seats 212, and the two ends of the footboard 22 are connected to the corresponding support seats 212 through pivots, which allows the footboard 22 to swing vertically.

[0020] The two footboards 22 correspond to two sets of support seats 212 respectively, so the two footboards 22 can swing independently.

[0021] Two electric telescopic rod assemblies 3 are installed on the tripod 21. The two electric telescopic rod assemblies 3 are symmetrically arranged on the tripod 21 to improve the stability of the tripod 21. Each of the two electric telescopic pole assemblies 3 drives the footboard frame 22 to swing, and the specific connection structure is as follows: Reference Figures 1-3 The electric telescopic pole assembly 3 includes a pole base 31 and a pole body 32; The pole seat 31 is hinged to the leg 21, and a threaded sleeve 33 is installed inside the pole seat 31. The threaded sleeve 33 rotates within the pole seat 31. The housings of the rod base 31 and the swing motor 34 are fixed, and the fixing method can be screw fixing; The output shaft of the swing motor 34 is a worm, and the outer ring of the threaded sleeve 33 is a worm wheel. The worm and worm wheel are connected to each other, so the swing motor 34 drives the threaded sleeve 33 to rotate. The inner ring of the threaded sleeve 33 is connected to the rod body 32, which is a lead screw. The threaded sleeve 33 and the lead screw are threadedly connected. One end of the rod 32 is hinged to the footboard 22, so the footboard 22 can swing up and down, and the rod 32 cannot rotate around itself. Therefore, the swing motor 34 drives the threaded sleeve 33 to rotate in both directions. When the threaded sleeve 33 rotates, the lead screw can extend and retract along the threaded sleeve 33. The extending and retracting lead screw drives the foot plate 22 to swing up and down.

[0022] The swing motor 34 can be a servo motor.

[0023] The other end of the rod 32 is screwed into a limiting nut 36. When the end of the rod 32 approaches the rod seat 31, the limiting nut 36 will block the rod seat 31, thus preventing the rod 32 from slipping off the rod seat 31.

[0024] The two swing motors 34 are located above the crossbar 211 and on one side of the footboard 22. This arrangement can reduce the interference of the swing motors 34 on the swing of the footboard 22.

[0025] Working principle: The two footrests 22 are controlled by two swing motors 34 with independent switches. Users can place the two footrests 22 in staggered positions to start staggered swing massage; users can also place the footrests 22 at the same angle to start synchronized foot swing massage; or a control chip can be used to set the starting position of the footrests 22, which can be the synchronized position of the two footrests 22 or the staggered position of the footrests 22.

[0026] Footrest 22 has the following structure for better massage, see reference. Figure 4 ,

[0027] The footrest 22 is rotatably connected to a first massage roller 41 and a second massage roller 42. The first massage roller 41 and the second massage roller 42 are connected to the footrest 22 through bearing seats. The first massage roller 41 and the second massage roller 42 can rotate to provide foot massage to the user.

[0028] Massage blocks are provided on the outer walls of massage roller 41 and massage roller 42.

[0029] The axes of massage roller 41 and massage roller 42 are arranged in parallel.

[0030] Both massage roller 41 and massage roller 42 are equipped with pulleys at their ends. Both massage roller 41 and massage roller 42 are equipped with a linkage belt 43, which links the two pulleys, so massage roller 41 and massage roller 42 can rotate synchronously.

[0031] The footrest 22 is equipped with a massage motor 44 that drives the first massage roller 41 to rotate.

[0032] The housing of the massage motor 44 is fixed to the footplate 22 by screws.

[0033] The footrest 22 has a rectangular frame structure. The massage motor 44 is located below the footrest 22 and is located on one side of the first massage roller 41 and the second massage roller 42. This orientation design reduces the rotational interference of the massage motor 44 on the first massage roller 41 and the second massage roller 42.

[0034] Reference Figures 5-6 The output shaft of the massage motor 44 and the shaft of the first massage roller 41 are also linked by a worm gear 35.

[0035] Reference Figure 4 It includes a fixed frame 1, which is a metal pole frame structure, and the two first vertical rods of the foot plate frame 22 are connected to the fixed frame 1.

[0036] Example 2, a lower limb massager, differs from Example 1 in that, referring to... Figures 7-9 The tripod 21 slides on the fixed frame 1; The inner side of the fixed frame 1 is provided with two inner slide rails, and the two first vertical rods of the foot 21 are provided with pulleys. These pulleys slide on the two inner slide rails, allowing the foot 21 to slide up and down along the fixed frame 1. A first vertical electric push rod 5 is hinged between the fixed frame 1 and the foot 21. The telescopic end of the first vertical electric push rod 5 is hinged to the connecting rod above the fixed frame 1, and the lower telescopic end of the first vertical electric push rod 5 is hinged to the foot 21.

[0037] Therefore, by controlling the extension and retraction of the first vertical electric push rod 5, the leg 21 can be controlled to slide up and down relative to the fixed frame 1.

[0038] The fixed frame 1 also has a sliding leg frame 71, and the leg frame 71 is fixed with a leg massage component 72 by screws. The leg massage component 72 can squeeze and massage the user's calves. This massage structure is a conventional technology in leg massage, and this embodiment will not provide further technical explanation.

[0039] A second vertical electric push rod 6 is hinged between the fixed frame 1 and the leg frame 71; the upper end of the second vertical electric push rod 6 is hinged to the rod body 32 of the leg frame 71, and the lower end of the second vertical electric push rod 6 is hinged to the middle rod body 32 of the fixed frame 1.

[0040] Therefore, by controlling the extension and retraction of the second vertical electric push rod 6, the leg frame 71 can be controlled to slide up and down relative to the fixed frame 1.

[0041] The mounting bracket 1 can be installed on the chair frame of the massage chair with screws.

[0042] Reference Figure 3The front end of the lead screw is fixed with a front retaining ring 8. The front retaining ring 8 and the limit nut 36 cooperate to control the front and rear extension of the lead screw through the mechanical partition rod seat 31. This design is to prevent the foot plate 22 from swinging too much when the swing motor 34 goes out of control, thus improving the safety performance of the user's foot massage.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
