[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] 1. The utility model is a back-supporting device with a pressure sensor, comprising a middle strap, a left shoulder strap and a right shoulder strap. The middle strap is provided with a middle-upper pressure sensor and a middle-lower pressure sensor. The two ends of the middle strap are respectively connected to the two ends of the left shoulder strap and the right shoulder strap. The left shoulder strap is provided with a left pressure sensor, and the right shoulder strap is provided with a right pressure sensor. Polarization motors are provided next to the sensors. When in use, when the user wears the utility model, the middle-upper pressure sensor is located at the upper part of the thoracic vertebra of the user's back, the middle-lower pressure sensor is located at the lower part of the thoracic vertebra of the user's back, and the left The pressure sensor is located at the top of the user's left shoulder, and the right pressure sensor is located at the top of the user's right shoulder; when the user has a physiological hunchback posture, the values ​​of the pressure data of the middle upper pressure sensor and the middle lower pressure sensor will differ greatly, and the corresponding polarization motor will vibrate to prompt the user to actively change to an upright posture; when the user has a physiological scoliosis posture, the values ​​of the pressure data of the left pressure sensor and the right pressure sensor will differ too much, and the corresponding polarization motor will vibrate to prompt the user to actively change to a neutral spine posture. The advantages of the utility model also include:

[0025] First point: the upper middle pressure sensor will collect pressure data from the upper part of the thoracic spine of the user's back, and the lower middle pressure sensor will collect pressure data from the lower part of the thoracic spine of the user's back. When the user has a physiological hunchback posture, the data values ​​collected by the two sensors will differ greatly, so the polarization motor will vibrate to remind the user to change to an upright posture; the left pressure sensor will collect pressure data from the top of the user's left shoulder, and the right pressure sensor will collect pressure data from the user's right shoulder. When the user has a physiological scoliosis, the data values ​​collected by the two sensors will differ greatly, so the polarization motor will vibrate to remind the user to keep the spine in a straight posture;

[0026] Second point: The utility model will continuously monitor the user's posture. When the user has a physiological hunchback or scoliosis, the polarization motor will actively vibrate to prompt the user to change his posture, thus forming a long-term and continuous monitoring and notification for the user, and generating communication with the user, so the prevention effect is better;

[0027] Third point: The utility model determines physiological kyphosis or scoliosis by judging the numerical difference between two pressure sensors, which is based on the body shape of each user, rather than using standardized data for judgment in general. Therefore, the utility model has good applicability to people of different body shapes;

[0028] Fourth point: Because the utility model is based on the numerical difference of each user, when the user grows from a child to a teenager or an adult, the utility model can still be used, so the utility model has a better continuous application effect;

[0029] Therefore, the utility model has good preventive effect and is suitable for a wide range of people.

[0030] 2. In the utility model, in a back-to-back device with a pressure sensor, the upper middle pressure sensor, the lower middle pressure sensor, the left pressure sensor and the right pressure sensor have the same structure. The upper middle pressure sensor includes a top cover, a circuit board and a base. One side of the circuit board is provided with a sensing crystal, a binding wire and a sensing solder joint, and is covered with a storage cover. The other side of the circuit board is provided with an analog-to-digital converter and a controller. The two sides of the circuit board are covered with a filling silicone, a top cover and a base. The bottom of the filling silicone is higher than the highest point of the binding wire. When the utility model is applied, when the utility model fits the back and shoulders of the user, the four top covers will receive pressure, and the pressure will then be sequentially input into the analog-to-digital converter through the sensing crystal, the binding wire and the sensing solder joint to become a digital signal, and then the digital signal is processed by the main controller to obtain pressure data; the filling silicone is used to transmit pressure, and it does not directly contact the binding wire, so the binding wire will not be broken by the filling silicone, so the service life of the pressure sensor is longer, and the service life of the utility model is longer. Therefore, the service life of the utility model is longer.

[0031] 3. In the utility model of a back-carrying device with a pressure sensor, the left shoulder strap is connected to the left sliding strap, the right shoulder strap is connected to the right sliding strap, and a fixing strap is also provided at the bottom of the middle strap. The left sliding strap and the right sliding strap are fixed to the left shoulder strap and the right shoulder strap in sequence after passing through the fixing strap. When the user wears the utility model and feels that it does not fit well, the left sliding strap and the right sliding strap can be removed from the left shoulder strap and the right shoulder strap, and then the left sliding strap and the right sliding strap are slid to adjust to a suitable length and then glued to the left shoulder strap and the right shoulder strap. Therefore, the utility model can be fine-tuned according to the user's body shape to improve the user's wearing comfort; the utility model also provides different sizes of code numbers, that is, different lengths of the middle strap, the left shoulder strap and the right shoulder strap. Therefore, the comfort of the utility model is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

Then the deformed top cover 4 is pressed on the top filling silicone 46, and the top filling silicone 46 is deformed again. Therefore, one end of the top filling silicone 46 located in the storage cover 45 is deformed, and then the end of the top filling silicone 46 located in the storage cover 45 produces an extrusion effect on the air or non-volatile protective liquid 55 located in the storage cover 45. The air or non-volatile protective liquid 55 is then pressed on the sensing crystal 5, and a Wheatstone bridge 56 is engraved in the sensing crystal 5. Then the Wheatstone bridge 56 converts the pressure into voltage data; the greater the pressure on the Wheatstone bridge 56, the greater the voltage data it outputs; the voltage data is then transmitted to the sensing solder joint 51 through the binding wire 52, and then the sensing solder joint 51 transmits the voltage data to the analog-to-digital converter 53, and the analog-to-digital converter 53 converts the voltage data It is a digital signal, which is then transmitted to the main controller 54, and the main controller 54 converts the digital signal into pressure data for output; the non-volatile protective liquid 55 covers the binding wire 52, so the top filling silicone 46 will not directly contact the binding wire 52, so the top filling silicone 46 will not break the binding wire 52, so the binding wire 52 can be used for a long time; the non-volatile protective liquid 55 has a low Eng viscosity and good fluidity, so when the non-volatile protective liquid 55 is subjected to the pressure of the top filling silicone 46, the pressure inside it is relatively gentle, so it will not cause the binding wire 52 to break; the number of sensing solder joints 51 is five, so other circuits can be connected later as needed; each sensing solder joint 51 is connected to two binding wires 52, when one binding wire 52 is broken, the other binding wire 52 can play the same data transmission role, so the service life of the utility model can also be extended.
