Piezoelectric sensing device for boxing training sandbag

Abstract

The invention discloses a piezoelectric sensing device for a boxing training sandbag. The device comprises an upper cover, a sensor body and a sandbag terminal, a mounting column is placed in the cavity; one end of the driven block away from the mounting column is fixedly connected with a spring; the mounting column pushes the driven block to move towards the positioning column; the driven block drives the spring and a push block to move towards the positioning column; the spring is in contracted state, one end of the push block is fixedly mounted at one end of the spring; the other end is matched with the clamping groove; the push block is inserted into the clamping groove; and is convenient for fixing positioning column, the outer shell is fixedly connected with the damp-proof shell; a data acquisition module can receive the information of the sandbag; a data calibration module can calibrate the data, the amplifier can amplify the information and process the data through the centralprocessing module and the data analysis module, the wireless starting module can store the information in the data storage module, and finally the information can be displayed through the display screen, so that the use effect is good.

Description

technical field [0001] The invention relates to the technical field of piezoelectric sensing devices, in particular to a piezoelectric sensing device for boxing training sandbags. Background technique [0002] The piezoelectric sensing device is a sensor based on the piezoelectric effect, which is a self-generating and electromechanical conversion sensor. Its sensitive element is made of piezoelectric material, and the surface of the piezoelectric material generates charges after being stressed. After the charge is amplified by the charge amplifier and the measurement circuit and the impedance is transformed, it becomes an electrical output proportional to the external force received. The piezoelectric sensor device is used to measure force and non-electric physical quantities that can be converted into electricity. Its advantages are wide frequency, High sensitivity, high signal-to-noise ratio, simple structure, reliable operation and light weight, etc. The disadvantage is ...
