Massage head connecting structure of a massage machine

Abstract

This utility model discloses a massage head connection structure for a massage mechanism, including a connector, a linkage mechanism, and a massage head. One end of the connector is connected to the eccentric wheel of the massage mechanism, and the other end is connected to one end of the linkage mechanism. The other end of the linkage mechanism forms a first branch and a second branch. The first branch is connected to the massage head, and the second branch is hinged to the housing of the massage mechanism. A limiting groove is provided on the side of the housing corresponding to the linkage mechanism to restrict the up-and-down movement of the linkage mechanism. During operation, the rotation of the eccentric wheel drives the connector to move, which is transmitted through the linkage mechanism. The second branch of the linkage mechanism is constrained by the limiting groove of the housing and the hinge point, converting the rotational motion of the eccentric wheel into the up-and-down movement of the massage head. This, combined with the neck massage head on the massage mechanism, achieves kneading massage. This utility model uses a linkage mechanism to achieve efficient and reliable motion conversion, with a compact structure, reliable operation, and low vibration and noise.

Description

Technical Field

[0001] This utility model relates to the technical field of massagers, and in particular to a massage head connection structure for a massage mechanism. Background Technology

[0002] Existing shoulder and neck massage mechanisms use an output motor to drive a gear set, which in turn drives the main shaft of the mechanism. Eccentric wheel assemblies are symmetrically mounted at both ends of the main shaft, with a shoulder massage component and a neck massage component mounted on each eccentric wheel assembly. Through the action of the main shaft and the eccentric wheels, the shoulder and neck massage components on both sides of the main shaft perform a massage, achieving a kneading massage effect on the shoulders and neck. This type of shoulder and neck massage mechanism is bulky, and the motion conversion mechanism of the shoulder massage head is not reliable enough, easily generating vibration and noise.

[0003] In view of this, this utility model addresses the numerous shortcomings and inconveniences caused by the imperfect design of the shoulder massage head motion conversion mechanism in existing shoulder and neck massagers. Through in-depth design and active research and development, this utility model was created. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a solution.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A massage head connection structure for a massage mechanism, characterized in that it comprises:

[0007] The connector has one end connected to the eccentric wheel of the massage mechanism and the other end connected to one end of the linkage mechanism;

[0008] A linkage mechanism, one end of which is connected to a connector, and the other end forms a first branch and a second branch. The first branch is connected to the massage head, and the second branch is hinged to the housing of the massage mechanism.

[0009] The massage mechanism housing has a limiting groove on the side corresponding to the linkage mechanism to restrict the up and down movement of the linkage mechanism.

[0010] Furthermore, the connector is a hollow collar with an extension arm at one end, which is sleeved on the eccentric wheel, and the connecting arm is connected to the linkage mechanism.

[0011] Furthermore, the linkage mechanism includes:

[0012] The first link has one end hinged to the extension arm of the connector;

[0013] The second link has one end hinged to the other end of the first link;

[0014] The third link has its middle part hinged to the other end of the second link, with one end forming the first branch and the other end forming the second branch.

[0015] Furthermore, the first branch and the second branch are arranged alternately, one above the other.

[0016] Furthermore, the first branch of the linkage mechanism is inserted into the massage head, and the first branch is fixed to the massage head by at least one fixing pin.

[0017] Furthermore, the third link of the linkage mechanism is a Z-shaped structure with a right angle or an obtuse angle, and the first branch of the third link and the second branch form an arc transition connection.

[0018] With the above structure, the massage head connection structure of the massage mechanism of this utility model achieves efficient and reliable motion conversion through a linkage mechanism. The rotational motion of the massage mechanism is converted into the up-and-down movement of the massage head through the ingenious linkage mechanism. The structure is simple and reliable. The cooperation between the limiting groove and the hinge point ensures the accuracy of the motion conversion process of the linkage mechanism. The linkage transmission method has a compact structure, which reduces the installation space requirement of the massage head and is suitable for miniaturized massage mechanisms. In addition, the linkage transmission method provides smooth movement and reduces vibration and noise. Attached Figure Description

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] like Figures 1 to 4 As shown, this utility model discloses a massage head connection structure 10 for a massage mechanism, including a connector 1, a linkage mechanism 2, and a massage head 3. One end of the connector 1 is connected to the eccentric wheel 20 of the massage mechanism, and the other end of the connector 1 is connected to one end of the linkage mechanism 2. The other end of the linkage mechanism 2 forms a first branch 21 and a second branch 22. The first branch 21 is connected to the massage head 3, and the second branch 22 is hinged to the housing 30 of the massage mechanism. A limiting groove 301 is provided on the side of the housing 30 corresponding to the linkage mechanism 2 to limit the up and down movement of the linkage mechanism 2.

[0031] During operation, the eccentric wheel 20 rotates, driving the connecting piece 1 to move. Through the transmission of the linkage mechanism 2, the second branch 22 of the linkage mechanism 2 is constrained by the limiting groove 301 of the housing 30 and the hinge point, converting the rotational motion of the eccentric wheel 20 into the up-and-down movement of the first branch 21. The first branch 21 drives the massage head 3 to realize the up-and-down massage action of the massage head 3. In conjunction with the neck massage head set on the massage mechanism, a kneading massage is realized. When the massage head 3 moves up, it works with the neck massage head to clamp the shoulders and neck. When the massage head 3 moves down, the shoulders and neck relax, realizing a massage effect that simulates the kneading of a human hand.

[0032] This utility model uses a linkage mechanism 2 to achieve efficient and reliable motion conversion. The ingenious linkage mechanism 2 converts the rotational motion of the massage core into the up-and-down movement of the massage head, resulting in a simple and reliable structure. The cooperation between the limiting groove and the hinge point ensures the accuracy of the motion conversion process of the linkage mechanism 2. The linkage transmission method results in a compact structure, which reduces the installation space requirement of the massage head 3, making it suitable for miniaturized massage cores. Furthermore, the linkage transmission method ensures smooth movement and reduces vibration and noise.

[0033] The connector 1 is a hollow collar 12 with an extension arm 11 at one end. The hollow collar 12 is sleeved on the eccentric wheel 20. The eccentric rotation of the eccentric wheel 20 drives the hollow collar 12 to move back and forth.

[0034] The linkage mechanism 2 includes a first link 23, a second link 24, and a third link 25. One end of the first link 23 is hinged to the extension arm 11 of the connector 1, and the other end of the first link 23 is hinged to one end of the second link 24. The middle part of the third link 25 is hinged to the other end of the second link 24. One end of the third link 25 forms the first branch 21, and the other end of the third link 25 forms the second branch 22. The first branch 21 and the second branch 22 are arranged alternately.

[0035] The first link 23 is hinged to the second link 24 and the connecting member 1. The second link 24 is hinged to the middle of the third link 25. The second branch 22 of the third link 25 is constrained by the hinge point of the housing 30 and the limiting groove 301 limits the entire linkage mechanism 2. This allows the forward and backward movement of the connecting member 1 to be converted into the up and down movement of the third link 25, thus realizing the up and down movement of the massage head 3. This utility model converts the rotational motion of the eccentric wheel 20 into the up and down swinging motion of the massage head 3 through the linkage mechanism 2, which, in conjunction with the neck massage head, achieves the clamping or relaxing of the shoulders and neck.

[0036] The first branch 21 of the linkage mechanism 2 is inserted into the massage head 3, and the first branch 21 is fixed to the massage head 3 by at least one fixing pin.

[0037] The third link 25 of the linkage mechanism 2 has a right-angled or obtuse-angled Z-shaped structure. The first branch 21 and the second branch 22 of the third link 25 form an arc transition, which facilitates the connection and operation of the second link 24 and the third link 25.

[0038] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
