Description

Technical Field:

[0001] The present invention belongs to the technical field of massage devices, and particularly relates to a massage mechanism, which particularly has kneading and acupressure massage functions and is suitable for being matched with a massage chair. Background Art:

[0002] The massage functions of existing massage chairs are generally divided into two categories. One is that it can move along a track to achieve large-range walking massage, and only one 3D manipulator needs to be configured; the other is fixed type, where massage mechanisms are distributed on both the back and the buttocks for fixed-point massage, mostly low-price products. The former has a strong sense of experience and can simulate the massage function of human hands. Currently, two massage rollers are provided on each of a pair of massage arms of the 3D manipulator, and the actions of the two massage rollers are the same, lacking variation, which is also a shortcoming of such a massage mechanism.

[0003] Taking the patent No. 201580001298.0, named massage device as an example, and many subsequent similar patents, all disclose a combination of two pairs of massage components to form more diverse massage techniques. The general structure includes a driving part, a rotating shaft, a conversion part, a first massage component, and a second massage component; the conversion part is an eccentric boss part and an inclined boss part, both of which are locked on the rotating shaft and are respectively used to drive the first massage component and the second component to generate a movement of approaching or separating. Due to the driving of the eccentric boss part and the inclined boss part, the actions of the first massage component and the second massage component are different, giving an inspiration of variation.

[0004] How to provide a technical solution with diverse massage techniques has thus become the object of research of the present invention. Summary of the Invention:

[0005] The purpose of the present invention is to design a massage mechanism with a combination of the yawing kneading movement of the first massage component and the undulating acupressure movement of the second massage component; the secondary purpose is that the second massage component also has a superimposed tapping action.

[0006] The technical solution of the present invention is realized as follows: A massage mechanism includes a first motor, a gearbox, a first massage component, and a second massage component. The first motor drives the first massage component and the second massage component to act after passing through the gearbox; two gear chains are symmetrically arranged in the gearbox, and the two gear chains are respectively meshed with a worm on the output shaft of the first motor through a worm gear; an eccentric shaft is fixed on the end gear shaft of the gear chain; it is characterized in that: the first massage component is locked at the end of a shaft section on the gearbox, and a swing arm is fixed in the middle of this shaft section. One end of the swing arm is linked with the eccentric shaft, and the other end is used to drive a slider to reciprocate; the massage arm of the second massage component can be swingably positioned on a horizontal shaft, and this massage arm is linked with the slider, and the reciprocating slider drives the second massage component to swing up and down.

[0007] Both ends of the horizontal shaft are processed with eccentric sections, and the massage arms in the second massage component are positioned on the eccentric sections; the horizontal shaft is in transmission connection with a second motor fixed on the gearbox.

[0008] Both ends of the swing arm are provided with pin shafts. One pin shaft is linked with the eccentric shaft through a first connecting rod, and the other pin shaft is inserted into the slot of the slider; the slider is linked with the massage arm of the second massage component through a second connecting rod.

[0009] The first massage component and the second massage component are located in the upper space of the gearbox. The eccentric shaft, the slider, the first connecting rod and the second connecting rod are all arranged below the gearbox. In the middle of the outer side of the bottom of the gearbox, there is a longitudinal convex rail, and the longitudinal convex rail is perpendicular to the long axis of the slot on the slider; the surface of the slider abuts against the longitudinal convex rail, restricting the slider to only move longitudinally back and forth.

[0010] The first massage component has two massage rollers, and the two massage rollers are correspondingly positioned at the ends of two sheet metal parts. The two sheet metal parts are locked on the same plastic part seat, and the plastic part seat is locked at the upper end of the shaft section and driven by the shaft section to swing left and right reciprocally; the second massage component has a massage roller, and the massage roller is positioned at the end of the massage arm. The massage arm passes through the reserved hole of the gearbox, and the lower end is connected with the second connecting rod, driving the second massage component to swing up and down around the horizontal shaft.

[0011] The present invention has the characteristics of unique concept, reasonable structure and reliable linkage; especially on the basis of the linkage, a certain degree of freedom is given to the second massage component so as to realize single or superimposed percussion actions under the drive of the second motor.

[0028] Refer to Figures 1 to 5 , the massage movement mechanism includes a first motor 1, a transmission 2, a first massage component 3 and a second massage component 4; two gear chains 21 are symmetrically arranged in the transmission 2, and the two gear chains 21 are respectively meshed with the worm 11 on the output shaft of the first motor through the worm gears 22; a fixed eccentric shaft 23 is provided on the final stage gear shaft in the gear chain 21, and the first massage component 3 and the second massage component 4 are driven by the eccentric shaft 23 to move, as Figure 3 .

[0029] Such as Figure 4 and Figure 5 , the first massage component 3 is locked at the end of a shaft section 5 of the transmission, and the shaft section 5 is fixed in the middle of a swing arm 6. One end of the swing arm 6 is linked with the eccentric shaft 23, and the other end is used to drive a slide block 7 to reciprocate; more specifically, the first massage component 3 has two massage rollers 31, and the two massage rollers 31 are correspondingly positioned at the ends of two sheet metal parts 32. The two sheet metal parts 32 are locked on the same plastic part seat 33, and the plastic part seat 33 is locked at the upper end of the shaft section 5 and is driven by the shaft section 5 to swing left and right. Between the massage rollers 31 of a pair of first massage components 3, a kneading action can be generated.

[0030] The massage arm 41 of the second massage component 4 can be swingably positioned on a cross shaft 42, and the massage arm 41 is linked with the slide block 7. The reciprocating slide block 7 drives the second massage component 4 to swing up and down. That is, the slide block 7 and the massage arm 41 of the second massage component 4 are connected through a second connecting rod 43 to form a traction type linkage.

[0031] More specifically, the second massage component 4 has a massage roller 31 that is the same as the first massage component. The massage roller 31 is positioned at the end of a massage arm 41. The massage arm 41 passes through the reserved hole 24 of the gearbox, and the lower end is connected to the second connecting rod 43, driving the second massage component to swing up and down around the horizontal axis 42.

[0032] Furthermore, a pin 61 is provided at both ends of the swing arm 6, one pin 61 is linked to the eccentric shaft 23 through the first connecting rod 62, and the other pin is inserted into the notch 71 of the slider. The eccentric shaft 23 can be directly formed on the final gear. In this embodiment, a plastic block 231 is locked on the final gear shaft, and an eccentric shaft is formed at the eccentric position of the plastic block. The final gear shaft drives the eccentric shaft 23 to rotate, and the swing arm 6 is pulled to swing through the first connecting rod 62. The swing of the swing arm 6 drives the shaft section 5 and the first massage component 3 to swing, and the two swing arms 6 jointly drive the slider 7 to reciprocate, and the second massage component 4 is driven to swing up and down with the help of the slider 7 and the second connecting rod 43.

[0033] The first massage component 3 and the second massage component 4 are located in the upper space of the gearbox 2. The eccentric shaft 23, the slider 7, the first connecting rod 62 and the second connecting rod 43 are all arranged below the gearbox 2. A longitudinal convex rail 25 is arranged in the middle of the outer side of the bottom of the gearbox 2. The longitudinal convex rail 25 is perpendicular to the long axis of the notch 71 on the slider 7. The surface of the slider 7 abuts against the longitudinal convex rail 25, restricting the slider 7 to only make longitudinal reciprocating motion. The shaft section 5 passes through the gearbox 2 in parallel with the eccentric shaft 23, and can be rotatably positioned on the gearbox through two bearings. The first massage component 3 is locked at the upper surface end of the gearbox, and the inherent swing arm 6 is locked at the bottom end. With the design of the through-type shaft section 5, the upper surface of the gearbox 2 is simple, and the bottom surface provides installation space for the linkage structure.

[0034] Furthermore, eccentric sections 421 are processed at both ends of the horizontal shaft 42, and the massage arm 41 in the second massage component is positioned on the eccentric sections 421; the horizontal shaft 42 is connected to the second motor 8 fixed on the gearbox 2, and more specifically, the output shaft of the second motor 8 and the horizontal shaft 42 are driven by a belt to achieve a first-stage speed change. The second motor 8 drives the horizontal shaft 42 to rotate, and the eccentric section 421 drives the second massage component 4 to shake at a high frequency to achieve the effect of tapping and beating. The eccentricity of the eccentric section 421 determines the magnitude of the tapping amplitude of the second massage component 4. Since both ends of the second connecting rod 43 have degrees of freedom, the massage arm 41 is allowed to shake up and down.

[0035] The second massage component 4 is additionally provided with a tapping action when driven by the second motor 8. It can work independently or cooperate with the first motor 1, so that the second massage component 4 is superimposed with the amplitude of the eccentric section 421 on the original fluctuation range, which greatly increases the massage amplitude, and each fluctuation contains multiple high-frequency tapping actions, which not only enriches the massage technique, but also greatly improves the vibration feeling.
