AI Technical Summary
Existing massage movements mostly use one or two pairs of rotating massage heads, which cannot achieve multi-head percussion massage. Moreover, percussion massage is mainly driven by eccentricity on handheld devices, making it difficult to achieve efficient percussion action in multi-head massage devices.
A multi-head percussion massage movement is designed. The inclined turntable is driven by a speed chain. The reciprocating motion of the massage heads is achieved by the cooperation of the piston rod and the 匚-shaped clamp, forming a multi-head percussion action. The motor drives the inclined turntable to rotate through the speed chain, and the undulation of the piston rod on the edge of the inclined turntable drives the massage heads to produce a percussion effect.
The alternating undulating and tapping motions of the massage heads in a multi-head massage device are realized, which enriches the massage experience and improves the massage efficiency and effect.

[0025] Refer to Figures 1 to 6, The multi-head percussion massage mechanism includes a housing 1, a motor 2, a speed-changing chain 3 and a massage head 4; the housing 1 includes an upper cover 11 and a lower shell 12; the motor 2 and the speed-changing chain 3 installed in the housing 1 are in a transmission relationship; at least one pair of speed-changing chains 3 are provided, symmetrically separated on both sides of the output shaft of the motor 2. For example, in this instance, a worm 21 is machined on the output shaft of the motor, and is transmitted to the respective speed-changing chains 3 through the worm wheels 22 symmetrically distributed on both sides of the large worm 21; output shafts 31 are provided on the same-speed gears 32 of the two speed-changing chains, and an inclined turntable 5 is locked on the output shaft 31. A piston rod 6 is provided outside the inclined turntable 5. One end of the piston rod 6 passes through the upper cover 11 of the housing and a massage head 4 is fixed at the end. The other end is movably sleeved in a sliding sleeve 13 formed at the bottom of the lower shell 12 of the housing, and maintains parallel to the output shaft 31, and under the drive of the inclined turntable 5, it reciprocates up and down relative to the housing 1, driving the massage head 4 to perform a percussion action on the human body. In addition, the cross-section of the piston rod 61 is selected to be non-circular, and the sliding sleeve 13 on the upper cover 11 and the lower shell corresponds to it, which can prevent the piston rod 61 from rotating.
[0026] Such as Figure 4 , The inclined turntable 5 includes a disc body 51, a disc cover 52 and an annular body 53; an L-shaped annular groove 511 capable of accommodating the annular body is formed on the outer edge of the disc body 51, and the annular body 53 is placed in the L-shaped annular groove 511 and is constrained by the disc cover 52 locked on the end face of the disc body 51, so that the annular body 53 does not rotate with the disc body 51 and is used to drive the C-shaped clamp 61. Therefore, the annular body 53 can be selected as a thrust bearing or nylon, and the upper and lower end face edges in contact with the C-shaped clamp 61 are designed as semi-circular edges. The inclined turntable is sleeved on the output shaft 31 through the disc body 51 and is constrained on the output shaft 31 by a snap ring 33 to achieve synchronous rotation.
[0027] Such as Figure 4 , Figure 5 And Figure 6 , A C-shaped clamp 61 is provided on the piston rod 6, and the C-shaped clamp 61 is clamped on the edge of the inclined turntable 5. The up and down deflection of the edge of the inclined turntable 5 can drive the C-shaped clamp 61 and the piston rod 6 to reciprocate up and down.
[0028] More specifically, the C-shaped clamp 61 is formed with two clamping feet 611, and the opposite surfaces of the two clamping feet 611 are both arc surfaces 612, and are clamped on the two surfaces of the annular body 53 of the inclined turntable by the two arc surfaces 612 to reduce the contact resistance; the C-shaped clamp 61 is formed with a pipe clamp 613 on the side away from the two clamping feet 611, and the pipe clamp 613 is sleeved on the piston rod 6 and is positioned by bolts or rivets.
[0029] In this example, a motor 2 with two output shafts is used, with two speed chains 3 symmetrically mounted on each shaft. Each speed chain 3 has only one piston rod 6 located outside the inclined turntable 5, forming a four-massage head 4 configuration. Depending on the position of the piston rod 6 on the inclined turntable 5, the four massage heads can be combined to move up and down synchronously, or in a pair-up, pair-down configuration as shown. Furthermore, the massage heads 4 can be spherical or flat, expanding the massage range.
[0030] Similarly, a single-shaft motor can be used, with two to four piston rods 6 evenly spaced along the edge of the tilting turntable 5. This creates a repetitive, flowing motion pattern, producing a diverse massage experience. Alternatively, the motor 2 can be an ultra-thin outer rotor motor, with a small gear fixed to the motor shaft and connected to two speed chains. This creates an ultra-thin, multi-head massage movement suitable for various massage devices.
[0031] In addition, the speed chain 3 mentioned above can be a single gear 32 as shown in the figure, or it can be a multi-stage gear transmission chain, depending on the motor speed and the designed knocking frequency; the motor output shaft can be reversing and changing speed through a worm gear, or a gear can be directly fixed on the output shaft and gear meshing transmission can be adopted.
