Abstract

Disclosed is an inertial percussion massager, including a percussion body provided with a free end and a drive end, a drive assembly, a drive strategy assembly, and a percussive massage portion arranged at the free end and configured to act on a target massage area in an impact manner to produce a percussive massage effect. The drive end is connected to the drive assembly. The drive strategy assembly is configured to control a motion strategy of the drive assembly and drive the free end of the percussion body to move at a frequency f. The frequency f is not less than 10 Hz. An inertia-based impact mechanism enables generation of a peak impact force stronger than that from traditional non-inertial percussion or pure vibration massage and facilitates more effective energy transfer even under same driving power, by optimizing mass distribution of the percussion body and/or increasing motion velocity.

Claims (55)

1. An inertial percussion massager, comprising:

a percussion body provided with a free end and a drive end;

a drive assembly;

a drive strategy assembly;

a percussive massage portion arranged at the free end and configured to act on a target massage area in an impact manner to produce a percussive massage effect;

the drive end is connected to the drive assembly;

the drive strategy assembly is configured to control a motion strategy of the drive assembly and drive the free end of the percussion body to move at a frequency f;

the frequency f is not less than 10 Hz and a support assembly; the support assembly partially encloses the percussion body to form an adaptively matched chamber based on a motion trajectory M of the percussion body; and the chamber comprises: a first opening; and wherein an opening face of the first opening intersects with the motion trajectory M of the percussion body; a second opening, being arranged opposite to the first opening; and an opening face of the second opening intersects with the motion trajectory M of the percussion body.

2. The inertial percussion massager according to claim 1 , wherein

the percussive massage portion is of a block structure or a layered structure; and

an average density ρ2 of the percussive massage portion is greater than an average density ρ0 of the percussion body.

3. The inertial percussion massager according to claim 1 , wherein

an orientation of an opening face of the first opening is consistent with the motion trajectory M of the percussion body.

4. The inertial percussion massager according to claim 1 , wherein

a general orientation P2 of the opening face of the second opening is consistent with the motion trajectory M of the percussion body.

5. The inertial percussion massager according to claim 1 , comprising:

an energy-storing elastic portion;

the energy-storing elastic portion is arranged at any position of a transmission path from the free end of the percussion body to the drive assembly; and

when the free end of the percussion body is obstructed by the opening face, elastic potential energy is accumulated during elastic deformation.

6. The inertial percussion massager according to claim 1 , wherein

a length L of the percussion body is not less than 2 cm; and

the length L is a maximum external dimension of the percussion body.

7. The inertial percussion massager according to claim 1 , wherein

the frequency f is 30-80 Hz.

8. The inertial percussion massager according to claim 1 , wherein

the frequency f is 40-60 Hz.

9. The inertial percussion massager according to claim 6 , wherein

a length L of the percussion body is 3-8 cm.

10. The inertial percussion massager according to claim 1 , wherein

an average density ρ1 of the free end of the percussion body is greater than an average density ρ0 of the percussion body.

11. The inertial percussion massager according to claim 1 , wherein

the support assembly comprises:

a first support arm, being located around a circumferential side of the percussion body.

12. The inertial percussion massager according to claim 11 , wherein

the support assembly comprises:

a second support arm, being arranged opposite to the first support arm; and

the percussion body is located between the first support arm and the second support arm.

13. The inertial percussion massager according to claim 12 , wherein

a shape of the first support arm comprises but is not limited to any one or a combination of more of a straight plate shape, an arc-shaped plate shape, a wavy plate shape, and a tapered cross-section plate shape; and

a shape of the second support arm comprises but is not limited to any one or a combination of more of a straight plate shape, an arc-shaped plate shape, a wavy plate shape, and a tapered cross-section plate shape.

14. The inertial percussion massager according to claim 1 , wherein

the support assembly comprises:

a third opening; and

an orientation P3 of an opening face of the third opening is consistent with an axial direction of the inertial percussion massager.

15. The inertial percussion massager according to claim 1 , wherein

a shape of the chamber comprises but is not limited to any one or a combination of more of a circular shape, an elliptical shape, a rectangular shape, a water drop shape, a leaf shape, and a biomimetic profile formed by composite curves.

16. The inertial percussion massager according to claim 1 , wherein

a shape of the percussion body comprises but is not limited to any one or a combination of a spherical shape, a cylindrical shape, an ellipsoidal shape, a polygonal prism shape, a wavy shape, a flattened elliptical shape, and a dumbbell shape.

17. The inertial percussion massager according to claim 1 , wherein

a shape of the inertial percussion massager is any one or a combination of more of a rod shape, a spherical shape, and a quasi-spherical shape.

18. The inertial percussion massager according to claim 17 , wherein

the inertial percussion massager comprises:

a secondary massage arm;

the percussion body is connected to the secondary massage arm to massage an in-vitro target massage area; and

the support assembly is connected to the secondary massage arm.
