[0014] The present invention provides a balance detection device for a self-balancing school bag, which has the following beneficial effects: (1) In the present invention, when the backpack body is placed on top of the long board, the backpack body will deform and tilt in the direction away from the rubber column under the action of its own gravity. When the backpack body tilts, it will pull the rubber column to move. The movement of the rubber column will pull the tension detection module. The tension generated by the tilt of the backpack body can be detected by the tension detection module. At the same time, it can be detected that the backpack is tilted and cannot maintain balance. When the tilt angle of the backpack is too large, the tension gradually increases. The detection module will control the motor to start working, and the transmission rod will drive the long board to rotate upward to prevent the backpack body from tilting too much and separating from the long board, affecting the balance detection of the backpack body. When the vibration module is started, the vibration module will drive the horizontal board to shake up and down.

[0015] (2) In the present invention, the horizontal plate drives the backpack body to shake up and down, and the shaking of the backpack body drives the slider to slide up and down. When the slider moves up and down, it drives the dynamic detection module to simulate the balance state of the backpack body under the motion state of the human body, so that the amplitude of the up and down shaking of the backpack body under the motion state of the human body can be detected. When the wax block moves forward, the wax block will contact the spring three. At this time, the wax block will rub the slider to reduce the friction force when the slider moves, so as to avoid excessive friction that affects the accuracy of the detection.

[0016] (3) In the present invention, when the shoulder strap rotates around the winding roller, the shoulder strap outside the storage box will become shorter. When the shoulder strap becomes shorter, the changes in the data of the dynamic detection module and the tension detection module under different lengths of the shoulder strap can be tested, thereby improving the adaptability of the device. When the waist belt is extended to the right, the left half of the waist belt will tighten the backpack body. When the left half of the waist belt tightens the backpack body, the backpack body in different states can be tested for balance. BRIEF DESCRIPTION OF THE DRAWINGS
