Description

Technical Field:

[0001] The utility model belongs to the technical field of massage equipment, and particularly relates to a multi-head massage component and a neck massage movement including the multi-head massage component. Background Art:

[0002] In existing massage devices, the massage components are all designed in a paired and symmetrical manner. Driven by the output shaft of the power mechanism, a pair of massage components rotate or swing synchronously in the clockwise and counterclockwise directions respectively to achieve a kneading action. The single or multiple massage heads configured in the massage components are also rigidly positioned. Even if the massage heads can rotate themselves to overcome the resistance when contacting the human body, when a pair of massage heads pinch and knead, there is a lack of elastic deformation margin, and the clamping force is large. Especially when pinching and kneading parts such as the neck and legs of a person with a larger body shape, the clamping force is often too large, resulting in discomfort or even pain, and on the contrary, there is a lack of strength. Taking the mainstream neck massage movement on the market as an example,

[0006] The thin sheet connecting the two support shafts on the swing arm forms a C-shaped structure. The two ends of the C-shaped structure are connected to the support shafts, and the middle is an elastic deformation section. The length of this elastic deformation section is between 10 mm and 25 mm, the thickness is between 2 mm and 4 mm, and the height is between 10 mm and 20 mm.

[0034] Refer to Figures 1 to 4, The multi - head massage component includes a massage head 1 and a swing arm 2. One end of the swing arm 2 is provided with two support shafts 21 for supporting the massage head 1, and the other end is provided with a shaft handle 22 that can be driven by an output shaft. The swing arm 2 is integrally formed of plastic. Between at least two support shafts 21, there is a thin sheet 23 with elastic deformation connecting them. The included angle between the thin sheet 23 and the force - applying direction of the massage head 1 is between 45 degrees and 90 degrees. That is, when working, the reaction force received by the massage head 1 can cause the thin sheet 23 to deform, and the massage head 1 does not act on the human body rigidly, which can be compatible with a relatively wide clamping range and achieve the function of self - adaptation.

[0035] Further, the thin sheet 23 connecting the two support shafts on the swing arm 2 has a C - shaped structure. The two ends of the C - shaped structure are connected to the support shafts 21, and the middle is an elastic deformation section 231. The length L of this elastic deformation section is between 10 mm and 25 mm, the thickness T is between 2 mm and 4 mm, and the height H is between 10 mm and 20 mm. Considering both the strength of support and the deformation ability, a thin sheet with a certain thickness is adopted, such as Figure 3 and Figure 4 .

[0036] Such as Figure 2 and Figure 4 , the two support shafts 21 face in opposite directions. Taking the horizontal state of the swing arm 2 as a reference, one is an upward support shaft 211 and the other is a downward support shaft 212. The included angle X between them is between 150 degrees and 180 degrees, and the included angle Y between the upward support shaft 211 and the swing arm 2 is between 80 degrees and 120 degrees. The massage head on the upward support shaft 211 can target the Fengchi acupoint, and the massage head on the downward support shaft 212 can correspond to the trapezius muscle. In order to expand the massage range of the trapezius muscle, a third support shaft 24 is also integrally connected to the elastic deformation section 231 of the C - shaped structure of the thin sheet 23. The third support shaft 24 faces close to the downward support shaft 212 and slopes outward. A massage head 1 is also sleeved on the third support shaft 24, which can be regarded as parallel to the massage head on the downward support shaft 212. The third support shaft 24 is also connected to the thin sheet 23 by a long thin arm and can also have a certain deformation ability. Also, due to the addition of the third support shaft 24, it may affect the deformation ability of the thin sheet 23. For this reason, a notch 232 is formed at the position of the elastic deformation section 231 corresponding to the third support shaft as compensation. In addition, since the third support shaft 24 is close to the downward support shaft 212, the upward support shaft 211 has a greater deformation amount to reduce the pressure on the Fengchi acupoint.

[0037] Further, according to different driving methods of the supporting massage movement mechanism, the shaft handle 22 on the swing arm 2 has the following two structures corresponding to the direction of the output shaft:

[0038] One, the output shaft is roughly parallel to the swing arm 2, such as Figure 5 and Figure 6The shaft handle 22 is integrally formed with a limit arm 25 for restricting rotation on one side of the C-shaped structure opening corresponding to the thin sheet 23. In this example, the output shaft is a shaft protrusion 63, which is not coaxial with the output shaft 61 of the gearbox.

[0039] 2. The output shaft is roughly perpendicular to the swing arm 2, such as Figure 7 and Figure 8 The shaft handle 22 is integrally formed with a stop pin 26 for restricting rotation on the side away from the support shaft. In this example, the output shaft is the eccentric section 611 of the output shaft.

[0040] According to the multi-head massage assembly provided above, there are two existing mainstream driving modes, and there are the following two specific embodiments.

[0041] Embodiment 1:

[0043] In order to prevent the massage component from rotating and only making reciprocating and oscillating motion, the limit pin 26 at the end of the limit arm 25 connected to the shaft handle 22 is inserted into the guide groove 41 of the upper cover of the shell 4. The guide groove 41 is parallel to the line connecting the two output shafts 61. Thus, a pair of massage components can produce reciprocating motion far and near, realizing the pinching and kneading action.

[0044] Furthermore, a synchronously rotating eccentric wheel 64 is provided at the lower end of the shaft disc 62 or the inclined shaft disc, and a traction rod 7 is sleeved by means of the eccentric wheel 64. The other end of the traction rod 7 is hinged to the middle part of a finger pressing arm 71. One end of the finger pressing arm 71 is movably hinged to the housing of the gearbox 6, and the other end is provided with a finger pressing head 72. The finger pressing head 72 can form light and heavy finger pressing actions independently, and can also form another set of far and near pinching and kneading actions with the massage head on the downward support shaft 212 or the massage head on the third support shaft 24.

[0045] Embodiment 2:

[0046] Reference Figure 7 and Figure 8, The neck massage mechanism has the same components as the previous example, except that there is an output shaft 61 on the transmission 6, which is nearly perpendicular to the swing arm 2 in the multi-head massage component; the output shaft 61 extends correspondingly to both sides of the transmission, and the two ends of the output shaft 61 are used to drive the multi-head massage component; wherein, both ends of the output shaft 61 have inclined heart sections 611, and the shaft handle 22 in the multi-head massage component is sleeved on the inclined heart sections 611, and the shaft handle 22 is driven by the inclined heart sections 611 to swing reciprocally; the limit pin 26 connected to the shaft handle is inserted into the guide groove 41 of the bottom shell of the housing, and the guide groove 41 is parallel to the output shaft 61, so that a pair of massage components can realize reciprocating changes in distance, and the pinching and kneading actions can be realized.

[0047] Furthermore, two eccentric wheels 64 are locked on the inner side of the inclined heart section 611 of the output shaft. A traction rod 7 is sleeved by means of the eccentric wheels 64. The other end of the traction rod 7 is hinged to a finger pressure arm 71. One end of the finger pressure arm 71 is movably hinged to the housing of the transmission 6, and the other end is provided with a finger pressure head 72.
