A calf fascia tapping massage structure

Abstract

This utility model relates to the field of massage device technology, specifically disclosing a calf fascia tapping massage structure. Addressing the technical shortcomings of existing massage devices, such as insufficient depth of action, significant vibration transmission, and limited contact point distribution, this structure uses a drive motor to rotate an eccentric wheel, which in turn drives a rigidly connected drive arm in a high-frequency linear reciprocating motion perpendicular to the front of the housing. The massage execution unit achieves precise fascia tapping through massage balls extending to the outside of the housing. A vibration buffer component is nested within the drive arm's movement path, using a guide channel to absorb lateral vibrations. This structure breaks through the limitations of traditional rotary massage trajectories, converting mechanical energy into vertical impact force, significantly improving the efficiency of deep tissue stimulation. Simultaneously, the rigid-flexible coupling buffer design suppresses vibration transmission, ensuring the stability and comfort of the massage action.

Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and in particular to a calf fascia tapping massage structure. Background Technology

[0002] Currently, calf massage devices generally employ three technical approaches: roller translation massage, multi-directional kneading massage, and airbag compression massage. Roller massage mechanisms relax muscles by rotating rollers along the leg surface, but their linear motion trajectory makes it difficult to generate impact force perpendicular to the body surface, resulting in low efficiency in stimulating deep fascia tissues. Kneading massage mechanisms use a biomimetic clamping structure to simulate human hand kneading movements, but the swing amplitude of the robotic arm is limited, failing to generate high-frequency vibration waves. Airbag massage mechanisms rely on intermittent pressure changes, which can improve superficial blood circulation, but lack the mechanical impact force generated by a rigid transmission structure, limiting their effectiveness in improving muscle fibrosis.

[0003] Existing technologies have the following common defects: Limited power transmission method: The traditional rotary motor combined with crank connecting rod drive mode has a motion trajectory that is mostly arc-shaped, making it difficult to generate a straight reciprocating impact motion perpendicular to the body surface, resulting in mechanical energy not being effectively converted into the vertical vibration energy required by the fascia layer; Insufficient vibration suppression: When the drive mechanism is rigidly connected to the massage execution unit, the lateral vibration generated by the high-speed rotation of the eccentric wheel is directly transmitted to the outer shell, which not only generates operating noise, but also causes the massage contact point trajectory to deviate, reducing the massage accuracy. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a calf fascia tapping massage structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a calf fascia tapping massage structure, comprising: a housing having an internal installation space; a drive motor fixedly disposed inside the housing; an eccentric transmission assembly including an eccentric wheel connected to the output shaft of the drive motor; a reciprocating motion mechanism including a drive arm fixedly connected to the surface of the eccentric wheel, the drive arm reciprocating linearly in a direction perpendicular to the front of the housing under the rotational drive of the eccentric wheel; a massage execution unit including a massage ball disposed at the front end of the drive arm and extending to the outside of the housing; and a vibration buffer assembly sleeved on the movement path of the drive arm, the interior of which is provided with a guide channel for the drive arm to pass through.

[0006] The present invention is further configured such that: the drive motor is a dual-axis output type motor, and each of its two output shafts is connected to an eccentric wheel; the drive arm is provided in two sets, which are respectively connected to the two eccentric wheels.

[0007] The present invention is further configured such that: the vibration buffer assembly includes: a fixed base, a positioning groove installed on the inner wall of the housing via a connector; an elastic buffer, covering the outer periphery of the fixed base; the guide channel passes through the fixed base and the elastic buffer, and the drive arm passes through the guide channel of the fixed base and the elastic buffer in sequence.

[0008] The present invention is further configured such that: the fixed base is provided with mounting holes, and a screw is passed through the mounting holes to achieve a fixed connection with the housing.

[0009] The present invention is further configured to include a massage head mounting base, which is fixedly mounted on the front end of the drive arm, and the mounting base extends at least two branch rods, with the massage ball mounted at the end of each branch rod.

[0010] The present invention is further configured such that: multiple massage head mounting seats are spaced apart along the length of the drive arm.

[0011] The present invention is further configured such that: a bearing is provided between the drive arm and the eccentric wheel, the inner ring of the bearing is fixed to the surface of the eccentric wheel, and the outer ring is connected to the drive arm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When this structure is in operation, the drive motor drives the eccentric wheel to rotate. Through the rigid connection between the eccentric wheel and the drive arm, the rotational motion is converted into the reciprocating motion of the drive arm along a straight line perpendicular to the front of the housing, which drives the massage ball to generate high-frequency mechanical impact. When the drive motor works in high-frequency mode, the guide channel axially constrains the linear motion of the drive arm, avoiding energy loss caused by lateral swing; the elastic buffer generates deformation damping during the high-speed reciprocating process of the drive arm, absorbing lateral vibration energy.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] like Figure 1-3 As shown, this utility model discloses a calf fascia tapping massage structure, which includes: a housing 1 with an internal installation space; a drive motor 2 fixedly disposed inside the housing 1; an eccentric transmission assembly including an eccentric wheel 3 connected to the output shaft 21 of the drive motor 2; a reciprocating motion mechanism including a drive arm 4 fixedly connected to the surface of the eccentric wheel 3, the drive arm 4 performing linear reciprocating motion (i.e., vertical direction) in a direction perpendicular to the front of the housing 1 under the rotational drive of the eccentric wheel 3; a massage execution unit including a massage ball 5 disposed at the front end of the drive arm 4 and extending to the outside of the housing 1; and a vibration buffer assembly 6 sleeved on the movement path of the drive arm 4, the interior of which is provided with a guide channel 63 for the drive arm 4 to pass through.

[0019] When this structure is in operation, the drive motor 2 drives the eccentric wheel 3 to rotate. Through the rigid connection between the eccentric wheel 3 and the drive arm 4, the rotational motion is converted into the linear reciprocating motion of the drive arm 4 along a straight line perpendicular to the front of the housing 1, which drives the massage ball 5 to generate high-frequency mechanical impact. When the drive motor 2 is working in high-frequency mode, the guide channel 63 axially constrains the linear motion of the drive arm 4 to avoid energy loss caused by lateral swinging; the elastic buffer 62 generates deformation damping during the high-speed reciprocating process of the drive arm 4 to absorb lateral vibration energy.

[0020] The drive motor 2 is a dual-shaft output type motor, with each of its two output shafts 21 connected to an eccentric wheel 3; the drive arm 4 is provided in two sets, which are respectively connected to the two eccentric wheels 3.

[0021] The vibration buffer assembly 6 includes: a fixed base 61, which is installed in the positioning groove 11 on the inner wall of the housing 1 via a connector; an elastic buffer 62, which covers the outer periphery of the fixed base 61; the guide channel 63 passes through the fixed base 61 and the elastic buffer 62, and the drive arm 4 passes through the guide channel 63 of the fixed base 61 and the elastic buffer 62 in sequence. In this embodiment, the elastic buffer 62 is a shock-absorbing rubber ring or a silicone ring.

[0022] The fixed base 61 is provided with mounting holes 64, and a fixed connection with the housing 1 is achieved by passing screws through the mounting holes 64.

[0023] It also includes a massage head mounting base 7, which is fixedly mounted on the front end of the drive arm 4. The mounting base extends at least two branch rods, and the massage ball 5 is mounted at the end of each branch rod. Multiple massage head mounting bases 7 are spaced apart along the length of the drive arm 4.

[0024] A bearing 8 is provided between the drive arm 4 and the eccentric wheel 3. The inner ring of the bearing 8 is fixed to the surface of the eccentric wheel 3, and the outer ring is connected to the drive arm 4.

[0025] Assembly process: First, fix the drive motor 2 to the housing 1. At this time, the output shaft 21 is located on the drive motor 2. Then, install the eccentric wheel 3 on the output shaft 21. Next, install the drive arm 4 with the bearing 8 embedded on the eccentric wheel 3. Next, put the elastic buffer 62 on the fixed base 61 and then lock it to the housing 1 with screws. Then, pass the drive arm 4 through the guide channel 63 of the elastic buffer 62 to complete the installation of the vibration buffer assembly 6 and the drive arm 4. Finally, lock the massage head mounting seat 7 to the drive arm 4 with screws and then insert the massage ball 5 into the massage head mounting seat 7 to complete the entire installation.

[0026] Working process: In operation, the drive motor 2 drives the eccentric wheel 3 to rotate eccentrically, and the rotational motion is converted into linear reciprocating motion of the drive arm 4 perpendicular to the front of the housing 1 through the bearing 8. The vibration buffer assembly 6 absorbs the lateral vibration generated by the movement of the drive arm 4 through the deformation damping of the elastic buffer 62, while the guide channel 63 constrains the movement trajectory of the drive arm 4. The massage ball 5 moves synchronously with the drive arm 4, generating high-frequency mechanical impact on the human fascia layer.
