Description

Technical Field

[0001] The utility model relates to the technical field of massagers, and particularly relates to an improvement of a motion mechanism of a massager. Background Art

[0002] A massager is a new generation of health care equipment developed based on physics, bionics, bioelectrics, traditional Chinese medicine and years of clinical practice. The massager can relax muscles, soothe nerves, promote blood circulation, strengthen cell metabolism, enhance skin elasticity, relieve fatigue, significantly reduce various chronic pains, acute pains and muscle soreness, relax the body, relieve stress and reduce skin wrinkles.

[0003] Chinese invention patent CN201710180709.8 discloses a percussion massager, which includes an electric reciprocating device with a reciprocating rod extending therefrom and a massage head detachably provided on the reciprocating rod and capable of generating a rebound when contacting muscles. A locking structure with a locking opening at the front end is fixedly provided at the outer end of the reciprocating rod, and a connecting structure inserted into the locking opening is fixedly provided on the massage head. Although this solution can achieve the massage effect by hitting the human body with the massage head, its percussion massage method is single, and it can only perform one-way telescopic strikes for massage and decompression. The contact area between the massage head and the user's skin is limited, and the percussion massage effect is poor. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a motion mechanism of a high-frequency percussion massager for the defects and deficiencies of the prior art. The moving range of its striking part is large, which can better contact with the user's skin and bring an excellent massage and relaxation experience to the user.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: It includes a motor, an eccentric shaft and a striking part. A first bearing is embedded in the center of the striking part. One end of the eccentric shaft is connected to the output end of the motor, and the other end of the eccentric shaft is sleeved in the first bearing. A counterweight is sleeved on the eccentric shaft. A housing is provided outside the motor.

[0006] Further, a flexible anti-rotation part is provided inside the housing. The flexible anti-rotation part includes a fixed block, a flexible anti-rotation column and a flexible limiting part. The fixed block is installed on the inner surface of the housing, and the flexible anti-rotation column and the flexible limiting part are installed on the fixed block. A limiting groove is opened at the bottom of the striking part, and the upper end of the flexible anti-rotation column is arranged in the limiting groove. The eccentric shaft drives the first bearing to rotate, and then drives the striking part to rotate at a high speed and perform a circular motion with a certain radius around the axis of the motor. The upper part of the flexible limiting column is arranged in the limiting groove opened at the bottom of the striking part, which restricts the high-speed rotation of the striking part and makes the striking part present a motion mode of performing a circular motion around the axis of the motor without self-rotation.

[0007] Furthermore, the counterweight is of a semi-circular structure, and the eccentric shaft passes through the center of the counterweight. When the motor drives the eccentric shaft to rotate, the counterweight sleeved on the eccentric shaft rotates with the eccentric shaft. When the semi-circular counterweight rotates, the overall center of gravity shifts outward, thereby driving the eccentric shaft to perform a circular motion with a certain radius around the axis of the motor.

[0008] Furthermore, a second bearing is sleeved on the eccentric shaft, and the second bearing and the flexible limiting part are located on the same horizontal plane. A second bearing is sleeved on the eccentric shaft. When the eccentric shaft performs a circular motion, the elastic limiting part and the second bearing cooperate with each other to limit the motion radius of the eccentric shaft, preventing damage to the motor caused by excessive torque due to too large a motion radius of the eccentric shaft, and protecting the durability and stability of the overall structure.

[0009] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: The motor, the eccentric shaft, the striking part and the flexible anti-rotation part cooperate with each other to make the striking part perform a circular motion of high-speed revolution without self-rotation, so as to achieve the effect of striking and massaging the human body. The circular vibration striking and massaging method has a larger massage range, is applicable to more massage scenarios and body parts, has high safety, and brings a better massage and relaxation experience to people.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] Refer to Figure 1 and Figure 2As shown in the figure, the technical solution adopted in this specific embodiment is as follows: A motion mechanism of a high-frequency percussion massager, which is composed of a motor 1, an eccentric shaft 2, a bearing, a flexible anti-rotation part 5 and a percussion part 3. A first bearing 31 is embedded in the center of the percussion part 3. One end of the eccentric shaft 2 is connected to the output end of the motor 1, and the other end of the eccentric shaft 2 is sleeved in the first bearing 31. The motor 1 drives the percussion part 3 to rotate at a high speed. A counterweight 21 is sleeved on the eccentric shaft 2. In this embodiment, a semi-circular counterweight is selected. The eccentric shaft 2 passes through the center of the counterweight 21. The motor 1 drives the eccentric shaft 2 to rotate, and the counterweight 21 sleeved on the eccentric shaft 2 rotates with the eccentric shaft 2. The semi-circular counterweight 21 makes the overall center of gravity of the eccentric shaft 2 shift outward, and then the eccentric shaft 2 drives the percussion part 3 to perform a circular motion with a certain radius around the axis of the motor 1. A housing 4 is arranged outside the motor 1 to protect the overall mechanism, block external dust, and prevent external factors from having a certain impact on the mechanism. Three flexible anti-rotation parts 5 are arranged inside the housing 4. The flexible anti-rotation part 5 is composed of a fixed block 51, a flexible anti-rotation column 52 and a flexible limiting part 53. The fixed block 51 is fixedly installed on the inner surface of the housing 4, and the flexible anti-rotation column 52 and the flexible limiting part 53 are installed on the fixed block 51. Three limiting grooves 32 are opened at the bottom of the percussion part 3. The positions of the limiting grooves 32 correspond to the positions of the flexible anti-rotation columns 52. The upper ends of the flexible anti-rotation columns 52 are arranged in the limiting grooves 32. The space in the limiting grooves 32 is slightly larger than the flexible anti-rotation columns 52. When the percussion part 3 rotates at a high speed, the upper ends of the flexible anti-rotation columns 52 are placed in the limiting grooves 32 to limit the rotation of the percussion part 3. At the same time, when the percussion part 3 performs a circular motion around the axis of the motor 1, the flexible anti-rotation columns 52 move in the limiting grooves 32, which will not affect the circular motion of the percussion part 3. The flexible anti-rotation part 5 of the present utility model selects a silicone flexible material. When restricting the rotation of the percussion part 3, the flexible material can buffer the percussion part 3 and then restrict the rotation of the percussion part 3, avoiding damage to the mechanism caused by forcibly restricting the rotation of the percussion part 3. When restricting the circular motion of the percussion part 3, the flexible anti-rotation columns 52 move in the limiting grooves 32 and deform slightly according to the circular motion of the percussion part 3. While not affecting the circular motion of the percussion part 3 around the axis of the motor, it restricts the high-speed rotation of the percussion part 3 itself, enabling the mechanism to operate normally. A second bearing 22 is sleeved outside the eccentric shaft 2. The second bearing 22 and the flexible limiting part 53 are located on the same horizontal plane. The flexible limiting part 53 of the present utility model adopts an arc-shaped structure, which is better adapted to the second bearing 22. The eccentric shaft 2 is sleeved with the second bearing 22. When the eccentric shaft 2 performs a circular motion, the elastic limiting part 53 and the second bearing 22 cooperate with each other to limit the motion radius of the eccentric shaft 2, preventing damage to the motor 1 caused by excessive torque due to too large a motion radius of the eccentric shaft 2, and protecting the durability and stability of the overall structure.

[0015] Working principle of the utility model: The motor 1 is connected to the eccentric shaft 2 to transmit power to the striking part 3 with the first bearing 31 embedded in the center, causing the striking part 3 to rotate at high speed and simultaneously move in a circular motion around the motor shaft. Under the stopping rotation action of the flexible stopping rotation column 52, the striking part 3 makes a circular motion of high-speed revolution without self-rotation, thereby achieving the effect of striking and massaging the human body.

[0016] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the utility model shall be covered within the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
