Electronic touch panel for swimming timing

Abstract

The invention provides an electronic touch panel for swimming timing. The electronic touch panel comprises a touch panel body, wherein a signal receiver is arranged in the touch panel body; the touchpanel body comprises a first waterproof layer and a second waterproof layer, and a 2-20nm air separation layer is arranged between the first waterproof layer and the second waterproof layer; a carbonnanotube fabric layer is arranged at the inner side of the first waterproof layer, and is weaved by a sensing yarn; the sensing yarn comprises a core yarn and two coating yarns, one coating yarn is spirally wound on the core yarn to form a yarn, and the other coating yarn and the previous coating yarn are spirally wound on the yarn to form the sensing yarn in the opposite direction; the first waterproof layer and the second waterproof layer are made of flexible waterproof material. A textile strain sensor adopts the testing principle that a conductive textile product is deformed along with theslight movement, the resistance or the capacitance is also changed along with the deformation, and the different states of a human body are sensitively reflected according to the change of the resistance or the capacitance; when the touch panel is applied, the change of water flow can be well detected; when a sportsman touches the touch panel, more sensitive response can be performed so as to obtain timing.

Description

technical field [0001] The invention belongs to the field of sporting goods, in particular to an electronic touch panel for swimming timing. Background technique [0002] Our country started relatively late in water sports electronic timing. Most of the large-scale competitions are imported foreign products, but the price of foreign products is too high. Although their product performance has tended to be perfect, the expensive price and technical blockade have prevented them from being widely used. Most of the domestic ones are still in the stage of single manual timing and table, which cannot be applied to the rapid development of domestic water sports. When the athlete is training by himself, if no one presses the watch on the side, he will not know his training situation every time. Therefore, a touch panel device that the athlete can trigger by himself is needed to record his own results. [0003] At present, the most critical thing in the electronic system of swimming...

AI Technical Summary

Problems solved by technology

[0004] As a key component of the automatic timing system for swimming competitions, the design requirements of the touchpad are quite high. It needs to be unresponsive to huge waves, but it can detect slight point touches.

However, most of the current touchpads cannot meet this precision requirement.

Although some touch panels can meet this requirement, they have complex structures, high costs, difficult maintenance, and poor reliability.

[0005] The electronic touch panel for domestic swimming competitions is not mature enough due to the technology, and the market response is not very good

The main reason is that the thrust trigger pressure is unstable, some are higher than the specified value and some are less than the specified value

The second is limited by the material technology, the thickness of the touchpad is about 10mm, and there are more than 10mm thickness

Domestic swimming electronic touch panels are mainly affected by the fact that the materials required for making touch panels do not meet the technical requirements, and there is a certain gap between them and foreign products.
