[0030] 300 - electric push rod DETAILED DESCRIPTION

[0031] Referring to Figures 1 to 6 , the lower limb massager comprises a leg massaging assembly 100 and a foot massaging assembly 200, and an electric push rod 300 is used to drive the foot massaging assembly 200 to make extension and retraction relative to the foot massaging assembly 200, so as to adapt to users with different leg lengths. This is also a common practice in the prior art.

[0032] The foot massaging assembly 200 comprises a massaging base 1, two separate foot chambers 2 and a driving mechanism 4 for driving the foot chambers to swing left and right, wherein:

[0033] Massage base 1 includes cover 11, massage side motor 12, massage side gearbox 13 and massage head 14; massage side motor 12 and massage side gearbox 13 are locked inside cover 11, massage side gearbox 13 is symmetrically distributed with two or more output shafts 15 corresponding to the position of the two foot compartments 2, in this example, two output shafts are arranged on one side, or three output shafts can be arranged on each side, forming massage of three areas of the sole, arch and heel. The massage head 14 is locked at the end of the output shaft 15 passing through the cover, and the massage head 15 is a massage turntable with massage points on the surface.

[0034] The foot compartment 2 is boat-shaped, has a cavity 21 for inserting feet, and a through hole 22 is formed in the bottom; air bags are arranged on both sides of the cavity 21, which can not only massage the feet tightly, but also hold and force the left and right to swing, improving the efficiency of exercise; the two foot compartments 2 are symmetrically distributed and are positioned above the massage base 1 by the front and rear guide shafts 3. More specifically, the guide shaft 3 for positioning the foot compartment is a coaxial shaft segment arranged at the front and rear ends of the bottom of the foot compartment 2 and supported by the shaft seat 16 locked on the massage base, and the through hole 22 is formed in the position between the two shaft segments of the bottom of the foot compartment 2. The through hole 22 corresponds to the number and position of the massage head 14 and is arranged in a front and rear linear shape. The shaft segment type guide shaft 3 is used for support, avoiding the middle part of the foot compartment 2, allowing the massage head 14 to intervene in the through hole 22 and protrude into the cavity 21 of the foot compartment, realizing the massage of the sole.

[0035] The biggest feature of this structure is that the massage head 14 is on one side of the massage base 1, in a non-contact relationship with the foot compartment 2, and does not participate in the swing movement of the foot compartment, but is exactly on the central axis of the swing of the foot compartment 2. The swing amplitude here is small, and the influence on the sole massage is small. From another angle, the change in the angle of the sole following the swing of the foot compartment 2 also changes the contact angle with the massage head 14, and the massage force also changes with the swing, which is an effect that traditional static foot compartments do not have.

[0036] Referring to Figure 5 and 6 , the drive mechanism 4 is arranged on one side of the massage base 1 corresponding to the position between the two foot compartments 2, and includes a swing side motor 41, a swing side gearbox 42, an eccentric wheel 43 and a traction arm 44; two eccentric wheels 44 are locked on the output shaft 45 of the swing side gearbox 42, and a sleeve 46 is slidably arranged outside the eccentric wheel 44; one end of the traction arm 44 is connected with the sleeve 46, and the other end is connected with the bottom of one side of the foot compartment 2, and the foot compartment is driven by the swing side motor 41 to make reciprocating swing movement around the guide shaft 3; in order to reduce friction, a bearing can be arranged between the sleeve 46 and the eccentric wheel 44. The output shaft 45 of the swing side gearbox and the guide shaft 3 have two setting schemes of vertical or parallel:

[0037] I. The out shaft 45 of the swing side gearbox is perpendicular to the guide shaft 3, one end of the traction arm 44 is positioned with the sleeve ring 46, and the other end is connected to the foot bin 2 through the cross shaft rod 47. The cross shaft rod 47 is a light shaft rod, one end of which has a vertical shaft hole 471. The light shaft rod is parallel to the guide shaft 3 and is rotatably positioned on the L-shaped shaft seat 23 at the bottom of the foot bin. The end of the traction arm 44 is positioned on the vertical shaft hole 471 to adapt to the change of the angle. In this example, the layout is symmetrical, the two out shafts 45 of the swing side gearbox are symmetrically distributed, and the traction arm 44 acts on the corresponding position of the foot bin 2. Figure 6 .

[0038] II. The out shaft 45 of the swing side gearbox is parallel to the guide shaft 3, the traction arm 44 is directly fixed on the sleeve ring 46, and the other end is connected to the foot bin 2 through the light shaft rod. The light shaft rod is parallel to the out shaft 45 and is rotatably positioned on the L-shaped shaft seat 23 at the bottom of the foot bin. This example is simpler, but the out shaft 45 is a front-to-back structure, and the two traction arms 44 are connected to the corresponding foot bins 2 in front and back. In addition, according to the layout inside the massage base 1, the swing side gearbox 42 can select a single out shaft 45 or use a double out shaft.

[0039] The two eccentric wheels 43 fixed on the out shaft 45 of the swing side gearbox are 180 degrees out of phase, and the two foot bins 2 are synchronously swung left and right. This is for the scheme of connecting the traction arm 44 to the adjacent side of the two foot bins 2. If the traction arm 44 is connected to the same side of the two foot bins 2, the two eccentric wheels 43 are in phase. In addition, if the distance between the two foot bins 2 is designed to be large enough, the two foot bins can also be designed to swing inward and outward synchronously. At this time, only a 180-degree mechanical delay is needed between the eccentric wheel and the out shaft 45, that is, the shaft hole of the eccentric wheel 45 is provided with a semicircular groove, and the out shaft 45 is provided with a key corresponding to the semicircular groove. By using the forward and reverse rotation of the out shaft 45, the two eccentric wheels 45 can rotate in phase or with a phase difference of 180 degrees. This is also a conventional technology.
