Description

Technical Field

[0001] This utility model relates to the technical field of massage components, and in particular to a massage mechanism. Background Technology

[0002] The massage mechanism is a crucial component of a massage chair, primarily designed to massage areas such as the neck, shoulders, waist, hips, and legs. Because the human body is curved, the massage mechanism needs to be adjustable in multiple dimensions to meet the varying intensity and amplitude of massage needs for different body parts.

[0003] Existing massage mechanisms include a frame, a running mechanism that drives the frame, and a massage mechanism mounted on the frame. The massage mechanism includes horn-shaped rocker arms and massage rollers at both ends of the rocker arms. Because the rocker arms are integrally formed or fixedly connected, the angle of the two horns of the rocker arms is fixed. Therefore, it is impossible to adjust the angle of the rocker arms according to the height and body size of the human body. As a result, the massage components at both ends of the rocker arms cannot fit the human body well, resulting in a relatively poor massage effect. Utility Model Content

[0004] The purpose of this utility model is to provide a massage mechanism in which the mounting base for installing the second massage component is configured to be rotatably connected to the connecting bracket, and a second tension spring is connected between the connecting bracket and the corresponding mounting base, so that the angle between the first massage component and the second massage component can be adaptively adjusted according to the user's body size.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a massage mechanism, including a frame, a running mechanism for driving the frame to run, and a massage mechanism disposed on the frame. The massage mechanism includes a drive shaft, two rocker arm assemblies disposed at both ends of the drive shaft, and a first drive device for driving the drive shaft to run. The rocker arm assembly includes a swing arm fitted on the end of the drive shaft and a connecting bracket rotatably connected to the other end of the swing arm. The connecting bracket has a first mounting arm and a second mounting arm.

A first tension spring is connected between the swing arm and the corresponding connecting bracket, and a second tension spring is connected between the connecting bracket and the corresponding mounting seat.

[0006] Furthermore, the connecting bracket has a hanging ear A in the middle area, the mounting base has a hanging ear B, the first end of the second tension spring is connected to the hanging ear A, and the second end of the second tension spring is connected to the hanging ear B.

[0007] Furthermore, the middle area of ​​the swing arm is provided with a hanging ear C, the connecting bracket is provided with a hanging ear D, the first end of the first tension spring is connected to the hanging ear C, and the second end of the first tension spring is connected to the hanging ear D.

[0008] Furthermore, the mounting base is rotatably mounted on the second mounting arm of the connecting bracket via pin a. The mounting base is capable of reciprocating between directions approaching and moving away from the first mounting arm. The mounting base has an accommodating space, and the second massage component is fixedly mounted within the accommodating space.

[0009] Furthermore, the second massage component is an audio vibration massager.

[0010] Furthermore, the swing arm includes a swing arm A and a swing arm B that are detachably and fixedly connected as one unit. A rotation space is formed at one end of the swing arm A and the swing arm B adjacent to the connecting bracket. The connecting bracket part extends into the rotation space and is rotatably set in the rotation space through the pin b.

[0011] Furthermore, the first massage component is a massage wheel rotatably mounted on the first mounting arm, and massage protrusions are provided on the peripheral wall of the massage wheel.

[0012] Furthermore, the first driving device includes a first driving motor and a reduction mechanism, wherein the first driving motor is connected to the drive shaft via the reduction mechanism.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, a massage mechanism includes a frame 10, a running mechanism 20 that drives the frame 10 to run, and a massage mechanism 30 disposed on the frame 10. The massage mechanism is installed on, but is not limited to, a massage chair. The frame 10 runs along a set running trajectory through the running mechanism 20 and performs human body massage on the user through the massage mechanism 30.

[0024] The massage mechanism 30 includes a drive shaft 31, two rocker arm assemblies 32 disposed at both ends of the drive shaft 31, and a first drive device 33 that drives the drive shaft 31 to rotate. Specifically, output sections are respectively provided at both ends of the drive shaft 31, and rocker arm assemblies 32 are provided on each output section. When the first drive device 33 drives the drive shaft 31 to rotate, the drive shaft 31 synchronously drives the rocker arm assemblies 32 at both ends to perform rocker arm movements, i.e., oscillating movements. The rocker arm assembly 32 includes a rocker arm 321 fitted onto the end of the drive shaft 31 and a connecting bracket 322 rotatably connected to the other end of the rocker arm 321. The connecting bracket 322 has a first mounting arm 3221 and a second mounting arm 3222. A first massage component 323 is mounted on the first mounting arm 3221, and a mounting seat 324 is rotatably connected to the second mounting arm 3222. A second massage component 325 is provided on the mounting seat 324. A first tension spring 326 is connected between the rocker arm 321 and the corresponding connecting bracket 322, and a second tension spring 327 is connected between the connecting bracket 322 and the corresponding mounting seat 324.

[0025] The massage mechanism of this invention features a mounting base 324 for mounting the second massage component 325, which is rotatably connected to a connecting bracket 322. A second tension spring 327 connects the connecting bracket 322 and the corresponding mounting base 324, allowing the angle between the first massage component 323 and the second massage component 325 to adaptively adjust according to the user's body size. In other words, the second massage component 325 can adaptively adjust the angle of the mounting base 324 relative to the connecting bracket 322 according to different pressures applied, thus ensuring that both the first and second massage components 323 and 325 can better conform to the human body to enhance the massage effect. In addition, the connecting bracket 322 is rotatably connected to the swing arm 321, and a first tension spring 326 connects the connecting bracket 322 and the swing arm 321, allowing the first and second massage components 323 and 325 on the connecting bracket 322 to synchronously and adaptively adjust their positions relative to the swing arm 321. This allows the first and second massage components 323 and 325 to better conform to the human body, increasing user comfort.

[0026] In some embodiments, the connecting bracket 322 is provided with a hanging ear A3223 in the middle region, and the mounting base 324 is provided with a hanging ear B3241. The first end of the second tension spring 327 is connected to the hanging ear A3223, and the second end of the second tension spring 327 is connected to the hanging ear B3241. This arrangement facilitates the installation of the second tension spring 327 on the connecting bracket 322 and the mounting base 324.

[0027] In some embodiments, the middle region of the swing arm 321 is provided with a hanging ear C3211, the connecting bracket 322 is provided with a hanging ear D3224, the first end of the first tension spring 326 is connected to the hanging ear C3211, and the second end of the first tension spring 326 is connected to the hanging ear D3224. This arrangement facilitates the installation of the first tension spring 326 on the connecting bracket 322 and the swing arm 321.

[0028] In some embodiments, the mounting base 324 is rotatably mounted on the second mounting arm 3222 of the connecting bracket 322 via a pin a3242. The mounting base 324 is capable of reciprocating between directions approaching and moving away from the first mounting arm 3221. The mounting base 324 has an accommodating space, and the second massage component 325 is fixedly mounted in the accommodating space. Specifically, the connecting bracket 322 is a sheet-like structure, and the accommodating space is slightly wider than the thickness of the connecting bracket 322, so that the mounting base 324 can rotate about the pin a3242 as the axis of rotation.

[0029] In some embodiments, the second massage component 325 is an audio vibration massager. For example, an audio vibration massager can be found in Chinese Patent CN221181016U, which discloses a voice coil vibration massager. Of course, the second massage component 325 may include, but is not limited to, an audio vibration massager, or other massage components, such as a massage roller.

[0030] In some embodiments, the swing arm 321 includes a swing arm A and a swing arm B that are detachably and fixedly connected as one unit. A rotation space is formed at one end of the swing arm A and the swing arm B adjacent to the connecting bracket 322. The connecting bracket 322 extends into the rotation space and is rotatably disposed in the rotation space by means of a pin b3212, so that the connecting bracket 322 is disposed between the swing arm A and the swing arm B and the connecting bracket 322 can rotate about the pin b3212 as the rotation axis, so that the connecting bracket 322 can rotate relative to the swing arm 321.

[0031] In some embodiments, the first massage component 323 is a massage wheel rotatably mounted on the first mounting arm 3221, and the massage wheel has massage protrusions on its peripheral wall.

[0032] In some embodiments, the first drive device 33 includes a first drive motor 331 and a reduction mechanism 332. The first drive motor 331 is connected to the drive shaft 31 via the reduction mechanism 332. The reduction mechanism 332 can be a belt drive. The output end of the first drive motor 331 is a pinion. The reduction mechanism 332 includes a gearbox, a drive shaft disposed in the gearbox, and a large gear disposed on the drive shaft. The pinion and the large gear are connected by a drive belt. The drive shaft is connected to the drive shaft 31. The transmission connection between the drive shaft and the drive shaft 31 can be a worm gear transmission.

[0033] In some embodiments, eccentric shafts 311 are respectively provided at both ends of the drive shaft 31, and the swing arms 321 on both sides are mounted on the corresponding eccentric shafts 311 by bearings, so that the swing arms 321 on both sides are eccentrically positioned at both ends of the drive shaft 31. Specifically, the output parts at both ends of the drive shaft 31 are the eccentric shafts 311. The eccentric shafts 311 are eccentrically positioned at both ends of the drive shaft 31 and are integrally formed with the drive shaft 31. The central axis of the eccentric shaft 311 is inclined to the central axis of the drive shaft 31, so that the eccentric shaft 311 is eccentrically positioned at both ends of the drive shaft 31. When the drive shaft 31 rotates, the eccentric shafts 311 can drive the swing arms 321 to perform corresponding swinging movements.

[0034] In some embodiments, the operating mechanism 20 includes a walking shaft 21 disposed at both ends of the frame 10 and a second driving device 22 that drives one of the walking shafts 21 to rotate. The second driving device 22 includes a second driving motor and a transmission mechanism, and the second driving transmission is connected to the walking shaft 21 through the transmission mechanism.
