Description

Technical Field

[0001] This utility model belongs to the field of massage equipment technology, and specifically relates to a massage mechanism, particularly a solution that can generate undulations under the drive of an offset shaft. Background Technology

[0002] Existing massage mechanisms all utilize electric motors for power, which, after being reduced in speed by a gearbox, drive the massage components to achieve a massage effect on the human body. The massage components have two types of movements: rotation and offset. Alternatively, a traction arm can drive another set of massage components to reciprocate, achieving a wider range of massage needs. However, the traction massage components can only reciprocate on a single plane, lacking variation in pressure. Furthermore, a single mold can only produce one specification of equipment.

[0003] The object of this invention is to find a more reasonable technical solution. Summary of the Invention

[0004] The purpose of this invention is to design a massage mechanism that uses an inclined plane to force the massage components to produce changes in pressure; a secondary purpose is that the massage mechanism can change product specifications by rotating the bearing block during assembly.

[0005] The technical solution of this utility model is implemented as follows: A massage mechanism includes a motor and a gearbox. After the motor is speed-changed by a gear chain in the gearbox, the vertical output shaft drives a first massage component and a second massage component respectively. The second massage component is characterized in that it is driven to reciprocate by an offset shaft segment linked to the output shaft. It includes a transmission ring and a traction arm hinged thereto. A finger pressure head is provided at the distal end of the traction arm. The transmission ring is movably sleeved on the offset shaft segment. The traction arm is constrained to reciprocate by a pin set on the gearbox. A mutually cooperating anti-slip inclined surface is also provided between the bottom surface of the traction arm and the pin or the gearbox. The anti-slip inclined surface causes the traction arm to perform overlapping undulating movements when moving near and far.

[0006] The pin fixed to the gearbox passes through the long groove on the traction arm, and the spring force of the spring always keeps the contact ramp of the traction arm in contact with the pin or the gearbox.

[0007] The spring acting on the traction arm has the following two assembly structures: 1. A spring is sleeved on the upper end of the pin shaft, and the lower end of the spring abuts against the traction arm with the aid of a lubricating pad; 2. A torsion spring is sleeved on the hinge shaft between the traction arm and the transmission ring, with one end of the torsion spring abutting against the transmission ring and the other end abutting against the traction arm.

[0008] The abutting inclined surface is provided on the bottom surface of the traction arm, or on the gearbox, or on the contact section between the pin and the traction arm.

[0009] The contact portion between the traction arm and the gearbox or pin shaft is provided with a matching contact slope.

[0010] The first massage component has two types: 1. A rotary massage disc, locked on the output shaft; the surface of the massage disc is provided with a massage head, and the bottom surface has an offset shaft section for driving the second massage component; 2. An oscillating massage disc, having a central hole and a massage head and a limiting arm protruding from the central hole, which is movably sleeved on the inclined shaft section of an inclined turntable on the output shaft via the central hole, the bottom surface of which has an offset shaft section for driving the second massage component; the limiting arm is constrained on the gearbox.

[0011] In a preferred embodiment, the last gear of the gear chain in the gearbox has a fixed output shaft. The output shaft is mounted in the gearbox's adapter slots on both sides of the last gear via shaft seat blocks. The shaft seat blocks are rotated 180 degrees and mounted in the adapter slots, which changes the position of the output shaft without altering the gear chain meshing relationship.

[0012] The gearbox includes an upper cover and a lower housing. The inner surfaces of the upper cover and the lower housing are formed with fitting grooves for mounting shaft seats. The upper cover has two shaft holes or an arc-shaped slot corresponding to the position through which the output shaft passes, and also has a through hole for fixing the pin.

[0013] The perforation on the top cover is an oblique elongated hole.

[0014] This invention features a unique design, ingenious structure, and reciprocating motion with overlapping undulations. By altering the motion plane of the traction arm through the contact with the inclined plane, the acupressure head generates undulations, simulating changes in the pressure applied by the acupressure. Furthermore, the output shaft is mounted on the gearbox via a shaft seat block. By rotating the shaft seat block 180 degrees, the position of the output shaft can be changed. One set of molds can assemble two specifications of massage cores, increasing the range of options. Attached Figure Description

[0027] Reference Figure 1 , Figure 2 and Figure 3 The massage mechanism includes a motor 1 and a gearbox 2. The motor 1, after being geared by a gear chain 3 in the gearbox 2, drives a first massage component 4 and a second massage component 5 via a vertical output shaft 31. The second massage component 5 is driven to reciprocate by an offset shaft segment 42 linked to the output shaft 31. The first massage component 4 has two types:

[0028] 1. A rotating massage disc is locked onto the output shaft; the surface of the massage disc is provided with a massage head 41, and the bottom surface has an offset shaft section 42 for driving the second massage component 5; the offset shaft section 42 is directly formed on the bottom surface of the first massage component 4, saving the assembly process.

[0029] 2. An oscillating massage disc has a central hole, a massage head 41 protruding from the central hole, and a limiting arm. It is movably mounted on an inclined shaft section of an inclined turntable on the output shaft via the central hole. The bottom surface of the inclined turntable has an offset shaft section 42 for driving the second massage component 5. The limiting arm is constrained on the gearbox 2 to prevent it from rotating with the inclined turntable.

[0030] The structures of the two first massage components 4 described above are both existing common structures. The only difference is that this design cleverly utilizes the bottom surface of the massage disc to form an offset shaft segment 42, which is linked with the output shaft 31 to drive the second massage component 5.

[0031] The second massage component 5 includes a transmission sleeve 51 and a traction arm 52 hinged thereto. An acupressure head 521 is provided at the distal end of the traction arm 52. The transmission sleeve 51 is movably fitted onto the offset shaft section 42. The traction arm 52 is constrained by the pin 6 and can only follow the reciprocating swing. The pin 6 is set on the gearbox 2 as a swing limit fulcrum. Between the bottom surface of the traction arm 52 and the pin 6 or the gearbox 2, there is also a mutually cooperating anti-collision inclined surface 522. The anti-collision inclined surface 522 is used to make the traction arm 52 move in a superimposed undulating motion when it moves near and far.

[0032] More specifically, the location of the abutting ramp 522 is relatively flexible. It can be located on the bottom surface of the traction arm 52, on the gearbox 2, or on the pin 6, that is, on the contact section between the pin and the traction arm 52, supported on the bottom surface of the traction arm. Alternatively, the contact portion between the traction arm 52 and the gearbox 2 or the pin 6 is provided with a mating abutting ramp 522. In other words, the abutting ramp 522 can be provided on one or both sides of the mating surface. Figure 2 and Figure 3 In this example, both the traction arm 52 and the pin 6 are provided with matching abutting slopes 522.

[0033] The pin 6, fixed to the gearbox 2, passes through the long slot 523 on the traction arm, and the spring force of the spring 61 keeps the contact ramp 522 of the traction arm in contact with the pin 6 or the gearbox 2. Conversely, if the contact ramp 522 is located on one side of the pin 6 or the gearbox 2, the spring force keeps the bottom surface of the traction arm 52 in contact with the contact ramp 522. This makes the undulation feedback more sensitive.

[0034] The spring 61 acting on the traction arm 52 has the following two assembly structures: First, the upper end of the pin 6 is fitted with the spring 61, and the lower end of the spring 61 abuts against the traction arm 52 with the help of the lubricating pad 62; the lubricating pad 62 reduces friction and does not hinder the movement of the traction arm.

[0035] 2. A torsion spring is fitted on the hinge shaft 53 of the traction arm 52 and the transmission sleeve 51. One end of the torsion spring abuts against the transmission sleeve 51 and the other end abuts against the traction arm 52.

[0036] The following section provides further explanation of the gearbox structure.

[0037] The gearbox 2 contains a gear chain 3. The final gear of the gear chain fixes the output shaft 31. The output shaft 31 is mounted in the adapter slot 23 of the gearbox on both sides of the final gear via shaft seat blocks 32. The shaft seat blocks 32 are rotated 180 degrees and mounted in the adapter slots 23. This allows the position of the output shaft 31 to be changed without altering the meshing relationship of the gear chain 3. In dual-output-shaft or multi-output-shaft massage mechanisms, changing the position of the output shaft 31 is equivalent to changing the specifications of the massage mechanism. More specifically, the gearbox 2 includes an upper cover 21 and a lower housing 22. The inner surfaces of the upper cover 21 and the lower housing 22 are formed with adapter grooves 23 for mounting shaft seats. The upper cover 21 has two shaft holes 211 or an arc-shaped slot corresponding to the position through which the output shaft 31 passes, to accommodate the changing position of the output shaft 31. It also has a through hole 212 for fixing the pin 6. The through hole 212 is an oblique elongated hole. The position of the pin 6 can be adjusted by using the through hole 212 to correspond to the output shaft, so as to adjust to the optimal massage trajectory of the second massage component 5.
