[0026] The present application is further described in detail below in conjunction with the accompanying drawings. When it is necessary to point out here, the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Combination Figure 1-3 As shown, a pressure sensing massage device comprises a base 12, a bracket, and a control device 7, a monitoring device, a driving device and a massage device mounted on the bracket;

[0028] Among them, the driving device includes a motor 2, a slide 3 and a linear guide 8. The mounting platform 9 on the right side of the slide 3 is fixedly connected to the permanent magnet 4. The permanent magnet 4 is fixedly connected to the massage device below through a spring 10 to solve the nonlinear problem of the repulsive force of the permanent magnet and realize the regulation of the massage intensity; the massage device is composed of a spherical capsule 6 and a permanent magnet 35 embedded in the capsule. The slide 3 can drive the upper permanent magnet 4 to move up and down, and use the principle of mutual repulsion of like magnetic poles to change the deformation degree of the spherical capsule 6 to realize the regulation of the massage intensity; the monitoring device is a TMR sensor 11, which is fixed to the upper surface of the second bracket 5 and connected to the control device 7, and is used to monitor the changes in the magnetic field around the spherical capsule 6 to realize the monitoring of the massage intensity.

[0029] Preferably, in the present invention, the spherical capsule 6 is fixedly connected to the second bracket 5 and has a three-layer capsule structure, the inner layer is a rigid layer 601, the middle layer is a flexible layer 602, and the outer layer is an elastic layer 603. The permanent magnet 35 inside the capsule is fixedly maintained with the N pole facing upward. The rigid layer 601 of the spherical capsule is made of carbon fiber composite material, the flexible layer 602 is made of polyurethane, and the elastic layer 603 is made of silicone. That is, the rigid layer 601 of the inner layer serves as a stable support for the entire capsule structure, can conduct the repulsive force of the permanent magnet, and reduce the loss of force during the transmission process. When the repulsive force transmitted from the rigid layer acts on the flexible layer 602, the flexible layer 602 undergoes moderate deformation and preliminarily amplifies the force. Finally, the elastic layer 603 of the outer layer produces a large elastic deformation, which further significantly amplifies the repulsive force and achieves high-efficiency output.

[0030] Preferably, the control device 7 in the present invention includes a control panel, a single chip microcomputer arranged in the control panel, and an information processing module for analyzing and processing the data of the TMR sensor 11.

[0031] Preferably, the device for driving the upper permanent magnet 4 in the present invention is an electric push rod, which includes a motor 2, a slide 3 and a linear guide 8. The top of the motor 2 is fixedly connected to the first bracket 1, the slide 3 and the linear guide 8 are slidably connected and the initial position is at the top of the linear guide, which is convenient for adjusting the massage intensity. The right side of the slide 3 is fixedly connected to the mounting table 9, and the bottom of the mounting table 9 is fixedly connected to the permanent magnet 4, and the permanent magnet 4 is fixed with the N pole facing downward.

[0032] When the whole device is in use, the whole device is started through the control panel, and the single chip microcomputer drives the slide table 3 to adjust the position accurately through the electric push rod according to the preset program. As the permanent magnet 4 gradually moves downward, the distance between it and the permanent magnet 35 inside the capsule below is continuously reduced. According to the principle that the same magnetic poles repel each other, as the distance between the two approaches, the repulsive force will increase accordingly;

[0033] At the same time, this magnetic field change will be captured by the TMR sensor 11 in real time and converted into a corresponding resistance value change. After the TMR sensor converts the magnetic field change into a resistance value change, it amplifies and filters the weak electrical signal through its own signal conditioning circuit, and then converts the analog signal into a digital signal through analog-to-digital conversion. The data is transmitted to the control device 7 in the form of an electrical signal through the built-in SPI communication interface;

[0034] After receiving the electrical signal transmitted by the TMR sensor 11, the control device 7 first analyzes and calculates it, and accurately determines the current massage intensity according to the preset corresponding relationship model between pressure, magnetic field strength, and electrical signal amplitude;

[0035] If it is detected that the massage force is too small and has not reached the set target value, the single chip will send a driving instruction to the electric push rod to drive the upper permanent magnet 4 to move further downward, thereby gradually reducing the distance between the two permanent magnets, increasing the repulsive force, and further causing the spherical capsule 6 to deform, ultimately increasing the massage force;

[0036] If the pressure is too great and exceeds the set threshold, the single chip microcomputer reversely drives the electric push rod to move a certain distance upward, increasing the distance between the permanent magnets, weakening the repulsive force, and appropriately reducing the deformation degree of the spherical capsule 6, thereby reducing the massage intensity.

[0037] Preferably, in the present invention, the second bracket 5 is fixedly connected to the first bracket 1, and the first bracket 1 is connected to the base 12 by a fixing screw. In addition, in order to prevent displacement during massage, a limb pad 13 is provided under the massage device, which can be used to place the upper limbs.

[0038] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
