[0002] Myoelectricity bracelet is a wearable device based on bioelectric signal (myoelectricity signal, EMG) detection technology. Myoelectricity signal is the electrical activity produced by the nervous system when giving instructions during muscle contraction and relaxation of the human body, and these signals are detected on the skin surface through electrode sensors. Myoelectricity bracelet can reflect the state of user's muscle activity by collecting and analyzing these signals, and is used for identifying gestures, controlling electronic devices, motion monitoring and rehabilitation training and other application scenarios.

[0003] Traditional myoelectricity signal detection equipment is usually large in size and complex in device, and is commonly used in medical environment for disease diagnosis, rehabilitation treatment and the like. With the development of electronic technology, sensor technology, microprocessor and wireless communication technology, myoelectricity signal detection equipment gradually develops towards miniaturization, portability and low power consumption. Myoelectricity bracelet as an innovative wearable device can be conveniently used in daily life, breaking the limitations of traditional equipment.

[0004] The existing myoelectricity bracelet uses a bracelet structure with attached electrode sheet and close to the human body to collect bioelectric signals of the human body, and the electrode sheet for collecting myoelectricity and the soft circuit for transmitting signals are generally subjected to encapsulation treatment at the same time during assembly, and are processed into a bracelet worn on the human body. The traditional design is prone to cause the electrode sheet to be not flat enough after encapsulation, affecting the myoelectricity collection efficiency. SUMMARY

[0005] The utility model provides a screw electrode myoelectricity bracelet aiming at the above problems, and the design concept lies in that the screw is used as the electrode sheet and is threadedly connected with the internal soft circuit, so that the position of the electrode sheet is fixed and can be performed after the encapsulation step, the assembly is convenient, and the wearing is flat.

[0006] A screw electrode myoelectric bracelet comprises a plastic shell 1 composed of a plastic upper shell 11 and a plastic lower shell 12, a large circuit board 74 loaded in the cavity formed between the plastic upper shell 11 and the plastic lower shell 12, a first circuit board 71 connected to the left side of the plastic shell 1 through wires 8, a second circuit board 72 and a third circuit board 73 connected to the right side of the plastic shell 1 through wires 8 in sequence, and a glue coating module 3 wrapped outside the collection circuit.

[0007] More specifically, a magnetic female socket 2 is arranged at the joint of the plastic upper shell 11 and the plastic lower shell 12.

[0008] During assembly, the large circuit board 74 loaded in the plastic shell 1 is connected to the first circuit board 71, the second circuit board 72 and the third circuit board 73 through wires 8, respectively; the wires 8, the first circuit board 71, the second circuit board 72 and the third circuit board 73 are glued by an external worker; finally, the screw electrode sheet 6 is screwed into the nut 9 on the first circuit board 71, the second circuit board 72 and the third circuit board 73 to complete the processing.

[0009] The technical effect of the screw electrode myoelectric bracelet is that the screw electrode sheet for collecting myoelectric signals can be installed on the myoelectric bracelet through threads after the glue coating of the collection circuit in the myoelectric bracelet is completed, so that the screw electrode sheet is prevented from being unevenly installed; the collection circuit after glue coating is greatly bent and stretched, and is suitable for arms with different arm circumferences; the magnetic female socket can be matched with a magnetic male charger for rapid charging.
