Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of massage chairs, in particular to a core flexible massage swing arm mechanism. Background Art
[0002] The existing massage chair is equipped with a movement for massaging human shoulders. The movement is designed with a swing arm mechanism to enable the movement to complete the kneading activity of the human shoulders. However, the existing swing arm mechanism can only enable the movement to move in a fixed position and cannot be adaptively moved according to the body shape of the experiencer. As a result, experiencers of different body shapes have different opinions when the movement is kneaded, and even have a poor experience when kneading the shoulders. Therefore, it is necessary to design and invent a massage swing arm mechanism that can detect the position of the human shoulder and adaptively move to complete the kneading action.

[0033] Reference Figure 1 , Figure 2 , Figure 4 A movement flexible massage swing arm mechanism includes a main frame 1 and a driving arm 2, one end of the driving arm 2 is movably connected to the main frame 1, and the other end is provided with a lower massage piece 3. Specifically, one end of the lower massage piece 3 is rotatably provided on the driving arm 2, and an upper massage piece 4 is rotatably provided in the middle, wherein the connection between the lower massage piece 3 and the driving arm 2 is called a first joint, and the connection between the upper massage piece 4 and the lower massage piece 3 is called a second joint, and the upper massage piece 4 and the lower massage piece 3 are adapted to the back curve of the human body through the cooperation of the first joint and the second joint.
[0034] Reference Figure 1-Figure 4 Specifically, the driving arm 2 is equipped with an elastic member that enables the upper massage piece 4 and the lower massage piece 3 to open and close, and is also provided with a limiting mechanism for limiting the opening and closing range of the upper massage piece 4 and the lower massage piece 3. In a specific embodiment, a grating sensor 13 is provided in the limiting mechanism, and the grating sensor 13 is connected to the main frame 1 through an electrical signal. When the main frame 1 moves to the shoulder of the human body, the elastic member is tightened to make the upper massage piece 4 and the lower massage piece 3 perform a closing action. When the upper massage piece 4 and the lower massage piece 3 are in a closed state, the upper massage piece 4 can be sensed by the grating sensor 13. At this time, the instruction can be conveyed to the main frame 1 through an electrical signal, so that the main frame 1 stays at the shoulder of the human body and drives the upper massage piece 4 and the lower massage piece 3 to perform a shoulder scraping action.
[0035] Reference Figure 1In a specific embodiment, the elastic member is a tension spring 5 , one end of the tension spring 5 is connected to the upper swing arm 401 , and the other end is connected to the lower swing arm 301 .
[0036] Reference Figure 2 and Figure 3 Specifically, the limiting mechanism includes an upper fixing plate 6 abutting against the upper massage piece 4 and a lower fixing plate 7 abutting against the lower massage piece 3, and also includes a sleeve 8 penetrating the upper fixing plate 6 and the lower fixing plate 7, and is equipped with two fixed end covers 9 embedded with the sleeves 8 on both sides. In this way, the upper fixing plate 6 and the lower fixing plate 7 clamp the upper massage piece 4 and the lower massage piece 3 from both sides, and the upper massage piece 4 and the lower massage piece 3 are opened and closed with the sleeves 8 as the fulcrum, and can only be opened and closed within the range limited by the upper fixing plate 6 and the lower fixing plate 7. When the upper massage piece 4 and the lower massage piece 3 are in the maximum opening and closing state, the tension spring 5 only needs to be stretched by a small part, so as to avoid the tension spring 5 being in an over-stretched state for a long time, thereby extending its service life.
[0037] Reference Figure 2-Figure 4 Specifically, the grating sensor 13 is installed on the upper fixed plate 6. Under such a configuration, when the upper massage piece 4 and the lower massage piece 3 are in an open or closed state, the grating sensor 13 can sense the light source. At this time, the grating sensor 13 is in an inactive state. When the upper massage piece 4 and the lower massage piece 3 are in a closed state, the light source of the grating sensor 13 is blocked by the upper massage piece 4, thereby changing to an activated state and conveying the shoulder scraping instruction through a point signal.
[0038] Reference Figure 3 The upper massage part 4 includes an upper swing arm 401 and an upper massage wheel 402, and the lower massage part 3 includes a lower swing arm 301 and a lower massage wheel 302. One end of the lower swing arm 301 is rotatably connected to the driving arm 2, and the upper swing arm 401 is rotatably connected to the middle part of the lower swing arm 301. The upper fixed plate 6 is installed on one side of the upper swing arm 401, and the lower fixed plate 7 is installed on one side of the lower swing arm 301, so that the shaft sleeve 8 is sequentially penetrated through the upper fixed plate 6, the upper swing arm 401, the lower swing arm 301, and the lower fixed plate 7, and then locked by the fixed end cover 9 to prevent the upper fixed plate 6 and the lower fixed plate 7 from detaching, and the upper massage wheel 402 and the lower massage wheel 302 are pressed against the human body to perform massage movement.
[0039] Reference Figure 6 and Figure 7 The main frame 1 is provided with a driving shaft 10 for making the driving arm 2 perform a kneading action, and the driving shaft 10 is provided with a width adjusting member for adjusting the width between the two driving arms 2. In this arrangement, when the driving shaft 10 performs a kneading action with a 3D effect, the width between the two driving arms 2 is controlled by the width adjusting member, so that the upper massage member 4 and the lower massage member 3 perform a lateral movement on the shoulder of the human body.
[0040] Reference Figure 6-Figure 8Specifically, the width adjustment member includes a width adjustment plate 11 fixed to the main frame 1 and an induction magnet 12 fixedly connected to the drive shaft 10. A plurality of induction gears are arranged in the width adjustment plate 11, which are used to cooperate with the induction magnet 12 to control the movement of the drive shaft 10 through electrical signals. Specifically, the induction gears are divided into five gears: narrow, narrow middle, middle, wide middle, and wide. When the drive shaft 10 moves, the induction magnet 12 rotates accordingly. When the induction magnet 12 rotates to the corresponding position, it senses the position of the corresponding gear on the width adjustment plate 11, and then conveys the command to the motor controlling the movement of the drive shaft 10 in the main frame 1 through electrical signals, so that the drive arm 2 can stay at a position that adapts to the width.
[0041] Reference Figure 1 and Figure 5 In a specific embodiment, an air bag is provided in the main frame 1 to push out the upper swing arm 401 and the lower swing arm 301. When the grating sensor 13 is activated, the instruction is also transmitted to the motor controlling the air bag through an electrical signal, so that the upper massage part 4 and the lower massage part 3 can fit the shoulders of the human body to adapt to people with thick shoulders.
