[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The core of the present invention is to provide a pressure measuring instrument for collecting pressure of a massager, which can be applicable to collecting pressure of a massager and can meet the requirements of measurement accuracy.

[0036] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Specifically, please refer to Figure 1-Figure 6 The present invention provides a pressure measuring instrument for collecting pressure of a massager, comprising: a pressure module, a fixing module and a control module.

[0038] Among them, the pressure module includes a movable support plate 204, a strain gauge, a strain gauge mounting plate 203 and a pressure plate 201. The movable support plate 204 is used to be close to the part of the human body to be tested. The strain gauge is arranged on the strain gauge mounting plate 203 and is used to generate deformation when the strain gauge mounting plate 203 is under pressure. The bottom of the strain gauge mounting plate 203 is hinged to the movable support plate 204 through at least two hinge components. The upper surface of the pressure plate 201 is used to be close to the massage part of the massager, and the lower surface of the pressure plate 201 is connected to the strain gauge mounting plate 203 through a ball joint.

[0039] The fixing module is connected to the movable support plate 204 and is used to fix the pressure module on the human body. The fixing module can set the pressure module on various parts of the human body such as arms, legs, waist, etc. Specifically, the fixing module can be fixed to the position to be tested according to the massage position required by the massager.

[0040] The control module is connected to the strain gauge and is used to convert the resistance change of the strain gauge into the pressure value of the measuring point. The control module can convert the resistance value of the strain gauge into the pressure value.

[0041] It should be noted that the strain gauge is a component composed of sensitive grids and other components used to measure strain. The working principle of the resistance strain gauge is based on the strain effect, that is, when the conductor or semiconductor material is mechanically deformed under the action of external forces, the resistance value of the strain gauge changes accordingly. This phenomenon is called "strain effect".

[0042] Compared with strain gauges, when thin film pressure sensors are subjected to pressure, the high conductive material layer and the pressure sensitive material layer are bonded together, the resistance changes, and the accuracy is poor. Therefore, they are only used to provide pressure changes and are not suitable for precise measurement.

[0043] In addition, the movable support plate 204 is close to the skin, the pressure plate 201 is close to the massage airbag of the massager, and the strain gauge is attached to the strain gauge mounting plate 203. The movable support plate and the strain gauge mounting plate 203 are connected in a hinged manner. This structure is well adapted to the measurement of different thicknesses of the human body, such as the arms, calves, thighs, and back. The pressure plate 201 is connected in a ball joint manner and can withstand pressure from all directions. In this way, the thickness can be made as thin as possible, which will not affect the normal operation of the massager, nor make the wearer feel uncomfortable, and can also adapt to various parts of the human body and accurately measure the massage pressure. When the strain gauge mounting plate 203 is under pressure, the strain gauge deforms and outputs the pressure value.

[0044] The pressure measuring instrument for collecting pressure of a massager provided by the present invention comprises a pressure module, a fixing module and a control module. The pressure module mainly comprises a three-layer structure consisting of a movable support plate 204, a strain gauge mounting plate 203 and a pressure plate 201. The movable support plate 204 is close to the human body, the strain gauge mounting plate 203 is hinged with the movable support plate 204, a strain gauge is mounted on the strain gauge mounting plate 203, and the pressure plate 201 is connected to the strain gauge mounting plate 203 through a ball joint. The pressure module is worn on the human body through the fixing module, the massager is covered on the pressure module and massages and presses the pressure plate 201, the pressure plate 201 transmits the pressure to the strain gauge mounting plate 203, the strain gauge mounting plate 203 drives the strain gauge to deform, and the control module is connected to the strain gauge to convert the resistance change of the strain gauge into the pressure value of the measuring point.

[0045] The pressure measuring instrument set up as above has a simple structure and a thin thickness, and can be applied to the pressure collection of massage instruments. At the same time, the three-layer structure of the pressure module is used to deform the strain gauge to measure the pressure, which can meet the requirements of measurement accuracy.

[0046] In a specific embodiment, the fixing module includes a housing 202 and a strap 3 .

[0047] The shell 202 has a hollow cavity for installing the pressure module. The shell 202 has a avoidance opening at the top of the hollow cavity for exposing the upper surface of the pressure plate 201. The movable support plate 204 is connected to the bottom of the hollow cavity of the shell 202. The strap 3 is connected to the shell 202 for being worn on the human body.

[0048] The function of the strap 3 is to fix the pressure gauge to the upper limbs, lower limbs, trunk and other human body positions. After wearing the pressure gauge, you can wear the massager.

[0049] The strain gauge is arranged on the strain gauge mounting plate 203, and a shell 202 is arranged outside the pressure module, which is convenient for cleaning and disinfection and for transmitting pressure. The strap 3 can also be adapted to measure human body parts of different thicknesses for easy fixation.

[0050] The housing 202 may be a silicone housing 202, or a housing 202 made of materials such as rubber or plastic.

[0051] The binding belt 3 can be a detachable binding belt 3. The two end edges of the binding belt 3 can be connected by a buckle assembly, or bonded by a nylon patch, or tied and connected.

[0052] The pressure plate 201 may be in the shape of a disc, or any other shape, as long as it can fit with the massage head of the massager and transmit the massage pressure downward.

[0053] In order to prevent the massager from affecting the operation of the control module when wrapping the pressure module, the control module can be connected to the strain gauge via the control line 101, that is, the control module is led away from the pressure module and the massager.

[0054] In addition, the outer side of the control module may be covered with a control box 1. The control box 1 may be a silicone box, or a box made of rubber, plastic or other materials, which may be selected according to actual conditions and will not be described in detail here.

[0055] Of course, the control module can also be arranged on a side of the fixed module away from the massage head of the massager to prevent misoperation during the measurement process.

[0056] The solution also includes a display terminal, and the control module is also connected to the display terminal for displaying the pressure value. The display terminal can be a mobile terminal such as a mobile phone, a tablet, a computer, etc., and can also be set on the pressure gauge to directly read it during the measurement process.

[0057] If the display terminal is a mobile terminal, the display terminal and the control module can be connected via Bluetooth. The display terminal is also used to generate a massage pressure curve.

[0058] Specifically, Figure 7As shown, the display terminal is connected to the main control board of the control module, and the main control board is connected to the strain gauge. After the massager is working, press the switch of the control box 1 and connect the mobile phone Bluetooth, the massage pressure can be displayed on the mobile phone APP, the massage pressure curve can be generated and saved, and the last pressure curve can be compared. You can also connect the computer with a wire to see the pressure curve on the computer.

[0059] In order to improve the measurement accuracy, the movable support plate 204 includes a plurality of support plate units arranged at intervals, and each support plate unit has at least one hinge assembly hinged to the strain gauge mounting plate 203. The hinge assembly is a hinge seat 2031.

[0060] Furthermore, the ball joint includes a ball joint bearing and a ball joint bearing seat that cooperate with each other, and one of the lower surface of the pressure plate 201 and the upper surface of the strain gauge mounting plate 203 is provided with a ball joint bearing, and the other is provided with a ball joint bearing seat. When the lower surface of the pressure plate 201 is provided with a ball joint bearing, the pressure plate 201 and the ball joint bearing are connected by a connecting column, and the ball joint bearing and the connecting column can form an integrally formed ball joint column 2011.

[0061] The hinged structure and the movable ball head joint structure make the pressure meter small in size and very thin in thickness. It is suitable for different parts of the human body and can collect pressures in different directions of the massager. It has relatively high accuracy and good repeatability. It is suitable for measuring the pressure value of the massager and provides a new method for measuring the pressure of the massager.

[0062] like Figure 3-Figure 5 As shown, the ball joint bearing is spherical, and the ball joint bearing seat is a ball socket wrapped in the spherical ball joint bearing. One end of the connecting column is connected to the ball joint bearing, and the other end is connected to the pressure plate 201. When the pressure plate 201 is subjected to the massage pressure of the massager, it drives the ball joint bearing to rotate in all directions relative to the ball joint bearing seat. The ball joint can transmit torque and has a simple structure.

[0063] Its working principle is:

[0064] The pressure plate 201 is close to the airbag of the massager, and the movable support plate is close to the skin. When the massager is working and the airbag is inflated, the pressure plate 201 is squeezed and acts on the strain gauge installation plate 203 through the ball head connecting column 2011. The strain gauge installation plate 203 and the strain gauge attached to it are deformed. After being collected by the main control board of the control module, a pressure value is output every second. It can be transmitted to the mobile phone wirelessly via Bluetooth, or it can be connected to the computer via wire, which is convenient for subsequent data processing and image generation.

[0065] The pressure measuring instrument for collecting pressure of a massager provided by the present invention is small in size, easy to wear, has high repetitive accuracy, is very low in cost, is not limited by time and space, and can flexibly measure the pressure value of a wearable massager. It effectively solves the problems of large volume of pressure sensors and inaccurate pressure values ​​of thin film pressure sensors in the prior art, and can be conveniently worn on the upper limbs, lower limbs, trunk, etc. of the human body to measure the massage pressure of an airbag massager or a mechanical massager.
