[0002] In the prior art, the 3D adjustment mechanism of the massage movement mostly adopts a drive motor and a worm gear transmission mechanism, and the 3D adjustment mechanism also rotates around a single shaft. Since the motor has a certain inertia, the adjustment position of the massage component is not accurate enough. At the same time, since the worm gear transmission mechanism is rigid and the force cannot be adjusted, the massage component is not flexible enough, which affects the massage function and the massage experience is poor. Summary of the invention

[0003] In view of the shortcomings of the prior art mentioned above, the technical problem to be solved by the present invention is to provide a massage movement with posture adjustment function, which can adjust the massage position and massage intensity of the user according to the body shape of different users, better fit the body curve of the user, and improve the massage comfort.

[0004] In order to solve the above technical problems, the present invention provides a massage movement with posture adjustment function, comprising:

[0005] frame;

[0006] A crank, wherein two ends of the crank in the extending direction are respectively a first end and a second end, and the first end of the crank is hinged to the frame;

[0007] A slide bar, two ends of which in the extending direction of the slide bar are respectively a first end and a second end, and the first end of the slide bar is hinged to the frame;

[0008] A massage base plate for mounting the massage assembly, one side of the massage base plate being hinged to the second end of the crank, and the other side of the massage base plate being opposite to the second end of the crank and being provided with a slider that slidably cooperates with the slider rod;

[0010] Preferably, the massage movement also includes a limiting mechanism for limiting the movement range of the massage substrate, the limiting mechanism includes a first lower limiting structure, a second lower limiting structure and an upper limiting structure, the first lower limiting structure is arranged on the side of the frame facing the massage substrate, the second lower limiting structure is arranged on the side of the massage substrate facing the frame, and the upper limiting structure is arranged at the second end of the sliding rod.

[0011] Preferably, the first lower limit structure includes a limit frame and a first limit block, the first limit block is mounted on the frame through the limit frame and abuts and cooperates with the side of the massage base close to the crank; the second lower limit structure includes a second limit block, the second limit block is arranged on the side of the massage base away from the crank and abuts and cooperates with the frame.

[0012] Preferably, the upper limit structure comprises a limit protrusion protruding from the outer peripheral wall of the sliding rod.

[0013] Preferably, the massage movement also includes a reset mechanism, which is respectively connected to the frame and the massage base plate.

[0014] Preferably, the reset mechanism comprises a tension spring, and two ends of the tension spring in the tension direction are respectively connected to the frame and the massage base plate.

[0015] Preferably, the control system also includes a controller, an inflator, an air pressure sensor and a pressure maintaining valve. The air pressure sensor is communicatively connected to the controller and is used to detect the air pressure in the regulating airbag. The pressure maintaining valve is used to maintain the air pressure in the regulating airbag. The inflator is communicatively connected to the controller and is connected to the regulating airbag through an air pipe.

[0016] Preferably, the first end of the sliding rod is connected to the frame via a joint structure, which includes a sleeve, a rotating shaft and a connecting screw. The sleeve is fixed to the frame, the rotating shaft rotates in the sleeve, and the connecting screw passes vertically through the rotating shaft and is coaxially threaded with the sliding rod.

[0017] Preferably, the frame comprises an open case shell and a support seat, wherein the support seat is arranged on the inner side wall of the open case shell and is hinged to the first end of the crank.

[0019] As described above, the massage movement with posture adjustment function of the present invention has the following beneficial effects: In the present invention, the crank, massage base plate, slide bar and slider together constitute a crank slider mechanism, and the regulating airbag of the control system serves as the power source of the crank slider mechanism. In this way, the massage base plate is equivalent to the connecting rod in the crank slider mechanism, so that the motion trajectory of the massage base plate conforms to the motion law of the crank slider mechanism, rather than a simple rotational motion. Since the massage component is installed on the massage base plate, the massage component moves with the massage base plate, ensuring that the massage part of the massage component is more in line with the user's body curve. When the massage component needs to adjust the posture relative to the user, the control system inflates the regulating airbag to expand the regulating airbag, and the massage base plate moves along the preset motion trajectory under the push of the regulating airbag. When the massage component moves to a suitable position to fit the user's body and perform massage, the human body generates a reaction force on the massage component, and this reaction force is balanced with the pushing force provided by the regulating airbag due to inflation. In addition, the control system controls the inflation and deflation of the airbag and the pressure holding time. The air pressure in the airbag can be detected and adjusted, so that the position and strength of the massage component relative to the user can be adjusted according to the body shape of the different users, better fitting the user's body curve and improving the comfort of the massage.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0054] like Figures 1 to 7 As shown, the present invention provides a massage movement with posture adjustment function, comprising:

[0055] Rack 1;

[0056] A crank 2, wherein two ends of the crank 2 in the extending direction are respectively a first end and a second end, and the first end of the crank 2 is hinged to the frame 1;

[0057] A slide bar 3, wherein two ends of the slide bar 3 in the extending direction are respectively a first end and a second end, and the first end of the slide bar 3 is hinged to the frame 1;

[0058] A massage base plate 4 for mounting the massage assembly 5, one side of the massage base plate 4 being hinged to the second end of the crank 2, and the other side opposite to the massage base plate 4 being provided with a slider 6 slidably matched with the slider 3;

[0059] The regulating system 7 includes an expandable and contractible regulating airbag 71 , and the regulating airbag 71 is arranged between the frame 1 and the massage base plate 4 .

[0060] In the present invention, the connection between the first end of the crank 2 and the frame 1 constitutes a first rotation pair, the connection between the second end of the crank 2 and the massage base plate 4 constitutes a second rotation pair, the matching part between the slide bar 3 and the slider 6 constitutes a moving pair, and the connection between the first end of the slide bar 3 and the frame 1 constitutes a third rotation pair, so that the crank 2, the massage base plate 4, the slide bar 3, and the slider 6 together constitute a crank slider mechanism, and the regulating airbag 71 of the control system 7 serves as the power source of the crank slider mechanism. In this way, the massage base plate 4 is equivalent to the connecting rod in the crank slider mechanism, so that the movement trajectory of the massage base plate 4 conforms to the movement law of the crank slider mechanism, rather than a simple rotational movement. Since the massage component 5 is installed on the massage base plate 4, the massage component 5 moves with the massage base plate 4, ensuring that the massage part of the massage component 5 is more in line with the user's body curve. When it is necessary to adjust the position of the massage component 5 relative to the user, the control system 7 inflates the regulating airbag 71 to expand the regulating airbag 71, and the massage base plate 4 moves along the preset movement trajectory under the push of the regulating airbag 71. When the massage component 5 moves to a suitable position to fit the user's body and perform massage, the body generates a reaction force on the massage component 5, and this reaction force is balanced with the pushing force F provided by the inflation of the regulating airbag 71. In addition, the control system 7 controls the inflation and deflation of the regulating airbag 71 and the pressure holding time, and the air pressure in the regulating airbag 71 can be detected and adjusted, so that the position and strength of the massage component 5 relative to the user can be adjusted according to the body shape of different users, so as to better fit the user's body curve and improve the massage comfort.

[0061] like Figure 5 As shown, the regulating airbag 71 has a multi-layer structure. When the regulating airbag 71 is expanded, it can meet the requirements of the pushing stroke of the massage base plate 4.

[0062] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, the massage movement also includes a limit mechanism 8 for limiting the motion range of the massage substrate 4, the limit mechanism 8 includes a first lower limit structure 81, a second lower limit structure 82 and an upper limit structure 83, the first lower limit structure 81 is arranged on the side of the frame 1 facing the massage substrate 4, the second lower limit structure 82 is arranged on the side of the massage substrate 4 facing the frame 1, and the upper limit structure 83 is arranged at the second end of the slide bar 3. The first lower limit structure 81 and the second lower limit structure 82 jointly limit the limit position of the massage substrate 4 close to the frame 1.

[0063] Furthermore, the above-mentioned first lower limit structure 81 includes a limit frame 811 and a first limit block 812. The first limit block 812 is mounted on the frame 1 through the limit frame 811 and abuts against the side of the massage base 4 close to the crank 2; the above-mentioned second lower limit structure 82 includes a second limit block 821. The second limit block 821 is arranged on the side of the massage base 4 away from the crank 2 and abuts against the frame 1.

[0064] like Figure 6 As shown, the upper limit structure 83 includes a limit protrusion 831 protruding from the outer peripheral wall of the slide rod 3. The limit protrusion 831 can prevent the slider 6 from slipping off the second end of the slide rod 3.

[0065] The massage movement further comprises a reset mechanism 9, which is respectively connected to the frame 1 and the massage base plate 4. When the regulating airbag 71 is in a non-inflated state or contracted, the reset mechanism 9 resets the massage base plate 4 to a limit position close to the frame 1.

[0066] Furthermore, the above-mentioned reset mechanism 9 includes a tension spring 91, and both ends of the tension spring 91 in the tension direction are respectively connected to the frame 1 and the massage base plate 4.

[0067] The control system 7 also includes a controller, an inflator (such as an air pump), an air pressure sensor and a pressure-maintaining valve. The air pressure sensor is connected to the controller for communication and is used to detect the air pressure in the regulating airbag 71. The pressure-maintaining valve is used to maintain the air pressure in the regulating airbag 71. The inflator is connected to the controller for communication and is connected to the regulating airbag 71 through an air pipe. The pushing force of the regulating airbag 71 on the massage substrate 4 is proportional to the air pressure inside it, so sufficient and appropriate pushing force can be ensured by adjusting the air pressure in the airbag 71. The air pressure sensor feeds back the measured air pressure to the controller to control the inflation time of the inflator and the air pressure holding time of the pressure-maintaining valve, so that the massage component 5 installed on the massage substrate 4 can adjust the position and strength relative to the user more accurately, thereby ensuring that the massage component 5 can fit different human body curves and provide a more comfortable massage strength acting on the human body.

[0068] like Figure 3 As shown, in order to facilitate the connection between the above-mentioned frame 1 and the sliding rod 3, the first end of the above-mentioned sliding rod 3 and the frame 1 are connected via a joint structure 31, and the joint structure 31 includes a sleeve 311, a rotating shaft 312 and a connecting screw 313. The sleeve 311 is fixed to the frame 1, and the rotating shaft 312 rotates in the sleeve 311. The connecting screw 313 vertically passes through the rotating shaft 312 and is coaxially threadedly connected to the sliding rod 3.

[0069] like Figure 2 As shown, the frame 1 comprises an open case 11 and a support base 12 . The support base 12 is disposed on the inner side wall of the open case 11 and is hinged to the first end of the crank 2 .

[0070] In order to improve the movement stability of the massage base plate 4 , the slider 6 is annular, and the slider 6 is embedded in the massage base plate 4 and sleeved on the slide rod 3 .

[0071] In summary, the massage core with posture adjustment function of the present invention can adjust the massage position and massage intensity of the user according to the body shape of different users, better fit the body curve of the user, and improve the massage comfort. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
